Description

The invention relates to a transport attachment, a traction means, a plate conveyor and a method for conveying conveyed along a plate conveyor.

Plate conveyors are used to transport conveyed on a transport surface, which is provided by a plurality of transport plates. The transport plates can be driven by means of cables and / or by means of at least one chain. When guiding the driven traction means such as steel cables and / or conveyor chains arise in particular in the cornering problems with the power dissipation of the forces occurring here. One of the forces involved is a necking force that can be described using the Euler-Eytelwein formula. In contrast to this constricting force, the driven conveyor chain and / or the driven steel cable should be supported as smoothly as possible in the direction of the center of the curve.

From the post-published document DE 10 2017 004 820 B3 a plate conveyor with transport attachments is known, which are fastened via connecting means to a driven traction means of the plate conveyor. In this case, a damping means can be arranged on a transport surface of the transport attachments.

The document US 5 042 648 A relates to a plate conveyor with sickle-shaped transport plates for conveying conveyed on a transport surface of the plate conveyor. The transport plates are connected via connecting means with a driven pull chain.

In the operation of a plate conveyor, there may be a considerable amount of noise, especially at idle and / or a change in direction of the traction device. Here, the transport plates can beat against lateral guides and / or against each other and / or rub, thereby causing a noise occurs.

The invention has for its object to provide a simplified plate conveyor, in particular, the noise pollution is reduced in the simplest possible way.

This object is solved by the subject matters of the independent claims. Preferred embodiments are the subject matters of the dependent claims.

One aspect relates to a transport attachment for a plate conveyor for conveying conveyed with a transport plate for conveying the conveyed on a transport surface of the transport plate. The transport attachment has a connecting device with a fastening means for fastening the transport attachment to a driven pulling means of the plate conveyor. Furthermore, the transport cap on at least one damping means which penetrates the transport plate from the transport surface to an underside of the transport plate, in particular completely penetrates.

The transport cap is designed and intended to be attached as part of the plate conveyor to the driven traction means of the plate conveyor. The transport attachment may e.g. be placed as an attachment and / or carriage on the driven traction means of the plate conveyor.

The driven traction means is preferably designed as a driven conveyor chain. In general, instead of the conveyor chain, another traction means may also be used, e.g. a steel cable, a rubber block chain, etc. The transport attachment can be fastened particularly securely on a conveyor chain, in particular at least in a form-fitting manner.

The transport attachment may be attached to the driven traction means such that the transport plate is at least partially disposed above and / or above the driven traction means substantially such that the transport surface faces upward in a substantially vertical direction. Here, the transport surface may be arranged in a substantially horizontal plane. This means that a normal to the transport surface can be oriented substantially vertically. When conveyed along a slope, slight deviations from the horizontal or vertical may occur, e.g. in the single-digit or two-digit degree range less than about 45 °, in particular less than about 25 °. However, in an operating position, the transport surface should always be oriented such that the normal points essentially vertically upwards onto the transport surface.

On the driven traction means of the plate conveyor, a plurality of identical transport attachments can be arranged. These plurality of transport essays can be arranged one behind the other on the driven traction means, in particular be placed on this. Here, the transport surfaces of the transport essays are arranged so that together they form a substantially continuous, movable conveyor surface on which the conveyed goods can be conveyed along the plate conveyor.

The transport plate may be lath-shaped and / or in the operating position substantially transversely to the conveying direction of the plate conveyor Be arranged above the driven traction means.

By means of the connecting device of the transport attachment to the driven traction means can be fastened. In this case, the connecting device can be arranged in particular on and / or under the transport plate. In particular, the connecting device may be arranged substantially centrally below the transport plate.

The connecting device and the transport plate are components of the transport attachment. The transport attachment may have additional components, which will be discussed below with reference to the embodiments. The connecting device has the at least one fastening means, with which the transport attachment can be attached to the driven traction means. The attachment can be done, for example, positive and / or non-positive. The fastening can take place, for example, by means of a screw connection, by means of a plug connection and / or by means of a clamping connection. In particular, the fastening means may comprise a clip means and / or latching means and / or a clamping means for receiving e.g. releasable Clips- and / or latching and / or clamping connection with the traction means. Thus, the transport attachment may e.g. be clipped on the traction means.

The connecting device can be designed such that the transport attachment can be detached from the traction means. Here, the connecting device is designed to provide a detachable connection. This makes it possible to solve in case of damage to the transport attachment only the damaged transport attachment of the traction means and / or replaced by an undamaged transport attachment.

Preferably, the attachment to the traction means is at least form-fitting, so that the fastening means is in engagement with the driven traction means. In this case, the fastening means may be formed so that it is provided and designed specifically for a predetermined type and / or shape of the conveyor chain. A positive fastening allows safe tracking of individual transport attachments.

The at least one damping means of the transport attachment can e.g. be formed as an elastomer and / or as a rubber coating and penetrates the transport plate substantially completely through the thickness or thickness of the transport plate through from top to bottom. With the strength of the transport plate in this case the direction of the narrowest extent in about vertical direction is meant (in the operating position of the transport plate). The damping means may e.g. have a modulus of elasticity of at most about 1 GPa, preferably at most about 100 MPa, more preferably at most about 30 MPa.

Due to the complete penetration of the transport plate, the damping means is particularly stable connected to the transport plate. This applies in particular if a region of the damping means is formed both on the transport surface and on the underside of the transport plate, which in each case has a greater extent than a connecting region of the damping means arranged between the transport surface and the underside. Such a connection region may be substantially formed as a channel, e.g. as a damping channel and / or as a buffer channel through which the damping means from the transport surface to the bottom (and / or vice versa) is injected through the transport plate. Thus, the damping means is inseparable (except by destruction) connected to the transport plate, which increases the resilience of the damping means.

The underside of the transport plate is in this case arranged on one of the transport surface opposite side of the transport plate. The bottom shows in a substantially vertical direction down. In this case, the underside can be arranged in a substantially horizontal plane. This means that a normal can be oriented substantially vertically on the underside. When conveyed along a slope, slight deviations from the horizontal or vertical may occur, e.g. in the single-digit or two-digit degree range less than about 45 °, in particular less than about 25 °. However, the bottom should always be oriented in an operating position so that the normal points downwards on the underside substantially vertically.

In the operating position of the transport plate a conveyed material can be conveyed on the transport surface of the transport plate, so that it can be conveyed e.g. solely due to gravity remains on the transport surface, without slipping from the transport plate.

When returning the transport attachments (and thus also the transport plates), the transport surface and / or the bottom can be aligned differently. Thus, the transport surface may be outside the operating position e.g. point down or point to the side. This is especially true in an endless circulating traction means.

The transport surface and the underside form the two largest surfaces of the transport plate.

The damping means can perform a plurality of functions. Thus, the damping means may be formed at an example exposed position of the transport attachment, which may encounter during operation of the plate conveyor, for example, to other transport attachments or guides. Thus, the impact is against the damping means, which reduces an ensuing noise. The damping means can thus be designed and provided as a noise damping means.

The damping means may also be formed on the transport surface of the transport plate as a static friction increasing means for conveyed along the plate conveyor conveyed. Therefore, conveyed articles deposited on the cushioning means are less likely to slip, particularly when conveyed along a slope, when the direction changes and / or when the (for example) abrupt (positive and / or negative) acceleration of the plate conveyor.

Thus, a solution is provided by which a damping means can fulfill several functions and at the same time is attached particularly stably to the transport attachment.

The transport attachment preferably has a plurality of such damping means, e.g. at least on each wing of the transport essay one.

According to one embodiment, the damping means has at least one adhesion region for the conveyed material conveyed along the plate conveyor, which protrudes at least partially from the transport surface. In this case, the adhesion region can protrude out of the transport surface by at least approximately 0.1 mm, specifically in a substantially vertical upward direction (in the operating position of the transport plate). The adhesive area allows secure storage of the conveyed on the transport surface. The damping means (and thus also the adhesion region) has a higher coefficient of friction than the remaining part of the transport plate, which is e.g. may be formed of a stiffer material and substantially allow the dimensional stability of the transport plate.

According to one embodiment, the damping means has at least one damping region, which protrudes at least partially from the underside of the transport plate. In this case, the damping region can protrude from the underside at least approximately 0.1 mm, specifically in a substantially vertical, downward-pointing direction (in the operating position of the transport plate). The damping area allows movement damping, especially when beat other components of the plate conveyor to the underside of the transport plate. As a result, a noise load can be reduced by the plate conveyor. The damping region has a higher modulus of elasticity than the rest of the transport plate, which substantially allows the dimensional stability of the transport plate.

In a development, the adhesive region is connected to the damping region through the transport plate along at least one damping channel. The damping channel may be formed as a connection area between the adhesion area and the damping area. The damping channel allows casting of the damping means both on the transport surface and on the underside of the transport plate in one piece.

In a further development of the damping region is formed as a survey on the underside of the transport plate, which in overlap with a countersinking surface of a transport plate in the conveying direction subsequent or preceding, identical transport attachment of the plate conveyor can be brought. Here, the transport plate on both a lowering surface and a survey. Countersink surface and elevation are designed such that, in successive transport plates in the conveying direction, the countersinking surface of a first transport plate is arranged below the elevation of a second transport plate. In other words, successive transport plates overlap each other such that (in the operating position), the lowering surface of the first transport plate is arranged below the elevation of the second transport plate. In another embodiment, the countersink surface of the second transport plate may be arranged below the elevation of the first transport plate. In the operating position, there is an overlap of two successive transport plates in an approximately vertical direction. Especially at such an overlap can be present by hitting a noise pollution, especially when the overlapping transport plates just do not transport conveyed, so are unloaded. The same can be done at idle, e.g. when the transport plates are returned (and are no longer in operating position). This arrangement of the damping means is a particularly efficient noise reduction.

Here, the transport plate may be formed in the conveying direction so step-like that a rear plate end of the transport plate overlaps at least partially with a front plate end of a transport plate downstream in the conveying direction, identical transport attachment. Likewise, the front plate end of the transport plate at least partially with a rear plate end of a transport plate in the conveying direction preceding, identical transport attachment overlap. The terms "rear" and "front" refer here to the conveying direction of the plate conveyor. The step-like overlap allows avoidance and / or reduction of gaps between the transport plates of the transport essays. In this embodiment, the transport plate is not formed exclusively with a smooth surface, but has at least one step and thus a recess and / or lowered counter surface, which a projection and / or a plateau of a preceding or subsequent transport attachment - viewed in a vertical direction - can overlap. In this case, for example, at least 25%, preferably at least 35%, of the transport plate may be formed as a vertically lowered sinking surface. This lowered part of the transport plate can be arranged in the operating position at least partially under a collection surface (as a transport surface) of a transport plate of a preceding or following in the conveying direction, identical transport attachment.

In addition, e.g. at least 25%, preferably at least 35%, of the transport plate be formed as a vertically elevated elevation surface. This elevated part of the transport plate can be arranged in the operating position at least partially over a countersinking surface of a transport plate of a conveying direction preceding or following, structurally identical transport attachment. The elevated part of the transport plate may be referred to as a survey of the transport plate and / or provide the transport surface on which the conveyed is promoted.

In a further development, at least one damping area is formed on a right-hand side of the transport plate laterally with respect to the conveying direction of the plate conveyor and at least one damping area on a laterally left-hand wing of the transport plate relative to the conveying direction of the plate conveyor. In this case, the transport plate on two wings, namely a right wing and a left wing. The two wings can be of different widths (in the conveying direction). In a middle region between the two wings, the connecting device may be formed. By providing at least one damping region per wing, a particularly efficient noise reduction can take place.

In a further development, at least one damping region arranged approximately centrally is formed on a lateral wing of the transport plate which is lateral in relation to the conveying direction of the plate conveyor, and at least one damping region arranged laterally approximately at the end is formed. In particular, at least one central and end-side damping region can be formed on both wings. Here, "approximately centrally arranged damping area" means that this damping area is arranged approximately at the lateral center of the respective wing, thus e.g. between about 30% and 70%, preferably between about 40% to about 60%, of the lateral length of the respective wing as measured from the center or midregion of the transport plate. Furthermore, "laterally approximately end-mounted damping region" means that this damping region is arranged at approximately the lateral end of the respective wing, namely at the wing tip. This may mean that the attenuation range is e.g. in the last lateral third, preferably in the last lateral fifth of the lateral length of the respective wing. This arrangement of the damping means is an efficient noise reduction.

According to one embodiment, the damping means has a buffer region which protrudes at least partially out of the underside approximately parallel to the conveying direction. The buffer area may protrude from the underside, at least in some areas at least approximately 0.1 mm, preferably at least approximately 0.2 mm, in a direction which is essentially parallel to the conveying direction of the plate conveyor (in the operating position of the transport plate). The buffer area allows buffering and / or damping of movement of other components of the plate conveyor relative to the transport cap, which strike the transport cap in or against the conveying direction. As a result, a noise load can be reduced by the plate conveyor. The buffer region has a higher modulus of elasticity than the remainder of the transport plate, which essentially allows the dimensional stability of the transport plate.

In one development, the adhesive region (or one of the adhesive regions) is connected to the buffer region through the transport plate along a buffer channel. The buffer channel may be formed as a connection area between the adhesion area and the buffer area. The buffer channel allows pouring of the damping means from the transport surface to the bottom of the transport plate in one piece.

In a further development, the buffer area is formed on the underside of the transport plate, that it is supported (in the operating state of the transport plate) at least partially in or against the conveying direction on a downstream or upstream, transportable attachment of the plate conveyor. In other words, the buffer area is formed at a position on the underside of the transport plate, which may strike in or against the conveying direction against an adjacent transport attachment. As a result, the noise can be reduced.

In a development, the at least one buffer area is formed on a supporting space for a carrying roller of the transporting attachment. The support station may be formed on the underside of the transport plate. At the support point, a carrying roller of the transport attachment can be attached and / or be. At the support point, the transport plate may have a substantially vertical stop surface, which may lead to a noise pollution. Therefore, the positioning of the buffer area at the support point can reduce the noise particularly efficiently.

In one development, the support station, on which the at least one buffer area is formed, is arranged laterally on the underside of the transport plate with respect to the conveying direction of the plate conveyor. In other words, in this case the buffer area is arranged adjacent to that carrying roller which is arranged at the lateral end of the transport plate. At the end, the risk of a stop to another component of the plate conveyor and thus the risk of noise is highest, especially in a curve guide. Preferably, in each case at least one buffer area is arranged on both lateral end rollers, more precisely on the two laterally arranged support locations.

In one embodiment, the damping means is formed as an elastomer and / or as a rubber coating. This allows both efficient damping and efficient increase of static friction.

In one embodiment, the transport cap has a plurality of damping means. All damping means of the transport attachment penetrate the transport plate from the transport surface to an underside of the transport plate completely. Thus, all damping means of the transport attachment to the advantages described above. In this case, each damping means may have at least one adhesion region which is formed on the transport surface, and at least one damping region and / or buffer region, which is formed on the underside of the transport plate.

One aspect relates to a traction means for a plate conveyor with a plurality of attached to the traction means transport attachments according to the preceding aspect. The transport essays can be uniformly spaced from each other along the entire traction means attached to the traction means. Furthermore, the transport attachments can all be fastened in the same orientation on the traction means, that is, e.g. such that the transport surfaces of the transport attachments form a substantially continuous conveying surface. In particular, the transport attachments may overlap at least partially. The traction means can be self-contained, e.g. be formed circular. The traction means may be formed in particular as a driven conveyor chain. In this case, for example, a transport attachment may be formed on each individual, on every second, or on every third chain link of the conveyor chain. Preferably, a transport attachment is attached to each individual chain link.

In general, the plate conveyor may include at least one change of direction of the conveying direction, e.g. at least one curve with a change of direction by at least 90 °. Along such a curve with a predetermined radius of curvature, the successive transport plates overlap substantially without gaps. This means that no one person's finger fits between the individual transport plates.

One aspect relates to a plate conveyor with a traction means according to the aspect described above. The plate conveyor has a drive such as e.g. a motor which drives the traction means along a predetermined Zugweges and / or conveying path. On the driven traction means, the plurality of transport attachments is attached and is driven together with the traction means to move along the predetermined Zugweges and / or conveying path.

In one embodiment, the traction means is guided by the plate conveyor along a helical curve. Here, the plate conveyor at least at one position has a helical curve, i. a curve with a slope. At this helical curve or helical curve conveyed goods can be transported on the conveying surface, which is formed by the transport surfaces of the transport essays, along the helical curve upwards and / or downwards. In particular, the items to be conveyed can be transported upwards at one position via a helical curve path and / or downwards again at another position of the plate conveyor, in particular along a second helical curve path of the same or another plate conveyor.

In one embodiment of the plate conveyor, the plate conveyor has a plurality of support rollers arranged on the helical curve path of the plate conveyor for supporting the lateral support surfaces of the transport attachments guided and / or driven along the helical curve path. These lateral support rollers are designed as Kurvenabstützrollen which are stationary fixed to and / or arranged on the conveyor track of the plate conveyor. In other words, these support rollers are not promoted and / or driven together with the traction means. The Kurvenabstützrollen serve for Recording the cornering forces by rolling on lateral support surfaces of the transport attachments conveyed along the helical curve path. Here, the lateral support rollers may be arranged substantially centrally along the path, in particular a piece offset to the center of the curve and / or helical axis from the center of the conveyor track, so that the lateral support surfaces of the transport attachments are guided along the support rollers.

In the rectilinear sections and in particular along the return paths of the traction means of the plate conveyor can be formed without support rollers.

1A shows a side view of a first plate conveyor 100 for conveying conveyed material along a helical curve path 103 , The first plate conveyor 100 is in the 1A . 1B . 1C and 1D not completely, but only partially shown. In particular, a traction means and transport plates of the first plate conveyor 100 only partially shown. Much of the helical curve 103 is rather shown without transport plates, without conveyor chain and also without lateral support rollers.

The first plate conveyor 100 has a pedestal 110 on, for supporting on a bottom of the plate conveyor 100 is trained.

1B shows the first plate conveyor 100 in a perspective view. In 1B are only schematically some transport essays 1 shown, each of which has a transport plate. The transport attachments 1 can be designed as a carriage and on a (not in 1 shown) conveyor chain as a traction means of the plate conveyor 100 attached, for example, be placed on the conveyor chain.

The plate conveyor 100 has a lower tail 105 and an upper tail 107 on. The lower tail 105 is with the upper tail 107 over a helical curve 103 connected. The helical curve 103 leads helically from the lower tail 105 around a spiral column 101 around along a helical conveying path to the upper tail 107 ,

In the illustrated embodiment of the plate conveyor 100 revolves the helical curve 103 the spiral column 101 a total of five times. In other embodiments, the helical curve may 103 more or less than five orbits around the helical column 101 include. In one embodiment, the helical curve 103 the spiral column 101 also partially like eg half circle. At the upper end of the track 107 is a substantially vertically sloping return surface 112 back to the bottom of the track 105 educated.

The plate conveyor 100 For example, it may be formed as a helical lift on which conveyed material from the lower tail 105 along the Wendelkurvenbahn 103 to the upper end of the track 107 can be promoted. The plate conveyor 100 can also be operated in the opposite direction, ie for conveying along the helical curve 103 from top to bottom.

Not in the 1A and 1B shown is a driven conveyor chain of the plate conveyor 100 , on and on the transporting attachments 1 are attached. The conveyor chain is provided as a circulating traction means and is from the lower tail 105 along the Wendelkurvenbahn 103 to the upper end of the track 107 guided and driven. The return of the self-contained conveyor chain takes place from the upper tail 105 along the return surface 112 steeply down and from a lower end of the return surface 112 on an underside of the plate conveyor 100 along back to the lower end of the track 105 , A drive of the conveyor chain can, advantageously at a lower or upper portion of the plate conveyor 100 be educated. For example, an upper and / or lower deflection roller of the plate conveyor 100 be designed driven, for example as a driven roller. These pulleys are in the 1A and 1B covered by the transport plates and therefore not shown. A lower pulley 160 is eg in 1D shown, which may be formed as a driven roller. The drive may be at least partially designed as a drive arranged outside a deflection roller, such as, for example, as a geared motor, or as at least one deflection roller with an internal motor, which may for example be designed as a drum motor.

On the shown plate conveyor 100 can conveyed along the helical curve 103 be conveyed in a vertical upward direction and / or in a vertical downward direction.

Along the Wendelkurvenbahn 103 orbits the helical conveying path and / or web surface of the plate conveyor 100 one in the 1A and 1B marked helix axis W of the plate conveyor 100 , which approximately with a cylinder axis of the helical column 101 coincides. The helix axis W represents in a view from above a curve center around which the conveyor chain and thus also the transport attachments 1 be guided.

1C shows in a view from above the plate conveyor 100 , Also in 1C are only a few of the transport essays 1 shown with the transport plates, namely those at the upper tail 107 and at the bottom end of the track 105 , Along the Wendelkurvenbahn 103 are the transport towers 1 not shown with the transport plates but omitted in the illustration. Along the Wendelkurvenbahn 103 Screw holes are designed for attaching static, lateral support rollers.

1D shows in a perspective view of the lower tail 105 of the plate conveyor 100 without conveyor chain and without transport attachments 1 , In the illustrated section of the conveyor track are two rails on a track surface 125 of the plate conveyor 100 arranged and trained. The rail closer to the helical axis W is arranged, is as an inside chain guide 122 educated. The other rail, which is further spaced from the helical axis W is arranged, is as an outside chain guide 121 educated.

Along the straight section of the conveyor track shown, the conveyor chain between the two chain guides designed as rails 121 and 122 guided. In curves, in particular along the helical curve 103 In order to reduce the friction and to absorb the constricting forces, the conveyor chain is not guided in such rails, but on the inner side of the conveyor chain arranged lateral support rollers 130 ,

In 1D is only one of the lateral support rollers 130 in extension of the inside chain guide 122 shown. The axis of rotation of the lateral support rollers 130 is essentially perpendicular to the web surface 125 educated. Thus, the axes of rotation of the lateral support rollers are arranged substantially parallel to a vertical direction, more precisely around the slope of the web surface 125 offset to the vertical direction.

The lateral support surfaces of the transport attachments attached to the conveyor chain 1 lie on the lateral support rollers 130 and are guided past them on the curve outside. The statically fixed lateral support rollers 130 can here to accommodate the cornering forces on lateral support surfaces of the transport attachments 1 roll.

The lateral support rollers 130 can be designed as horizontal ball bearings, which absorb the constricting forces and remove them rolling. As a result, negative influences of the resulting forces and be removed on the components of the plate conveyor 100 and 200 reduced.

At one (eg curve outside) lateral side cheek of the web surface 125 is an elongated side guide 120 For example, designed as a rail under which the transport essays 1 be passed. Through this side guide 120 can be a lifting of the transport attachments 1 prevented and / or reduced. On a (bend inside) opposite side, in the 1 D hidden perspective is also possible, such a side guide 120 be arranged. The side guides 120 can along the entire track area 125 as protection against interference between the lateral side cheek and the transport attachments 1 and / or be designed as lift-off protection. The side guides 120 For example, they may be formed as a hollow profile. On the side guides 120 is the lateral width of the conveyor track above the track surface 125 so far reduced that the lateral, so for example the inside and outside, plate ends of the transport essays 1 below the side guides 120 are arranged.

2A shows in a view from above a second plate conveyor 200 with a conveying surface 140 which is formed and / or guided along a right-hand curve. The second plate conveyor 200 This is not complete, but only partially shown. In 2A shown are a plurality of transport towers 1 , which on a driven conveyor chain 150 are attached as traction means. Every transport attachment 1 has a transport plate with a transport surface 10 on. The transport surface 10 all transport attachments 1 together form the conveyor surface 140 , Here are the transport surfaces 10 the forwardly driven transport attachments 1 arranged substantially in the same plane, with successive transport surfaces 10 partially overlap. The transport surfaces 10 those transport attachments 1 which are being returned and may therefore be overhead (not in 2A shown), can be different than in the plane of the conveying surface 140 be arranged.

In the in 2A Shown embodiment, the conveyor chain 150 initially driven along a rectilinear portion of the conveyor track, whereupon the conveyor chain 150 is guided along a curve which is formed in the embodiment as a right-hand curve and in the course of which the conveying direction changes approximately by 180 °. In the illustrated embodiment of the plate conveyor 200 the conveyance of conveyed goods takes place essentially in the same plane, namely a substantially horizontal plane, that of the transport surfaces oriented in the forward direction 10 is spanned. The promotion in a horizontal plane takes place in a similar way as the promotion along the helical curve 103 in the 1A to 1D shown first plate conveyor 100 ,

Every transport attachment 1 provides a transport surface 10 ready, which is in a direction substantially transversely (ie laterally) extended to the conveying direction larger than in the conveying direction. The conveying direction of a plate conveyor corresponds to the course and the drive direction of the driven conveyor chain 150 , The conveyor chain 150 as well as the transport attachments 1 are moving components of the plate conveyor 200 ie they become relative to statically fixed components of the plate conveyor 200 driven and / or moved. To the statically fixed components of the plate conveyor 200 include the lateral support rollers 130 which are arranged along the curve and around the conveyor chain 150 is guided. The lateral support rollers 130 are arranged so that their axis of rotation is arranged substantially in the vertical direction. The lateral support rollers 130 serve together with lateral support surfaces of the transport attachments 1 for receiving and / or for rolling the cornering forces when cornering the driven conveyor chain 150 must be included.

Lateral to the conveying direction are the transport surfaces 10 so far about the conveyor chain 150 about that by the lateral width of the transport surfaces 10 a web width B the conveyor track is defined. The web width B depends on the lateral extent of the transport plates 50 (cf., for example, for this 4 ) of the transport attachments 1 , Along the plate conveyor 100 and 200 have all transport attachments used 1 each have the same lateral extent, which of the respective web width B equivalent.

In curve guide along the plate conveyor 100 and or 200 become the transport plates 50 on one inside of the curve over and crammed together, while they are fanned out on a curve outside. Here are the transport plates 50 so formed and / or along the conveyor chain 150 arranged that they themselves in the curve guide (eg in view from above) a substantially gap-free conveying surface 140 form.

2 B shows in a view from below the second plate conveyor 200 , The lateral support rollers 130 who are at an in 2 B not shown web surface 125 are fastened, are formed only along the curve guide, but not along the straight-line routes of the conveyor track of the plate conveyor 200 , As a result, compared to conventional plate conveyors, the number of required support rollers can be reduced.

In the illustrated embodiment of the second plate conveyor 200 are the lateral support rollers 130 arranged along a semicircular circumference, so that a curve guide results in a direction change of the conveying direction of about 180 °. The transport plates 50 the transport attachments 1 have a bottom 20 on which in 2 B is shown. On the bottom 20 each transport tower 1 are in the illustrated embodiment a total of six laterally spaced support locations 31 formed, on which carrying rollers 30 can be arranged. In the embodiment shown are on each bottom 20 each transport tower 1 exactly two idlers 30 arranged, and in each case a support roller on each wing 30 , This means that both on a curve-inside wing in each case a carrying role 30 is arranged as well as on a curve outside wing in each case a supporting role 30 , Each wing has adjacent to a central region of the transport plate 50 and / or the conveyor chain 150 a support place 31 for a narrow track width, at a lateral end of the plate a support place 31 for a wide track width and in between a support station 31 for a middle track width. At each of these support places 31 can be a carrier role 30 be arranged and / or be.

The carrying role 30 can, for example, at the middle support place 31 be formed of the respective wing, or on one of the laterally arranged outside support sites 31 of the respective wing. The arrangement of the idlers 30 under the wings, for example, for the entire plate conveyor 200 be the same, from transport plate 50 to transport plate 50 vary, or at least partially vary. In the embodiment shown are different Abstützplätze 31 with a carrying role 30 occupied.

In other embodiments, for example, two support rollers 30 be provided per wing or three idlers 30 per wing, so that, for example, plate conveyors can be realized in which each transport attachment 1 with a total of six carrying rollers 30 is provided. This can be useful if a high delivery load is expected. The attachment of several idlers 30 can also allow for a relatively wide web width B can be realized.

One with a " A "Featured neckline at the bottom of the plate conveyor 200 is shown enlarged below.

2C shows the section A at the bottom of the plate conveyor 200 in an enlarged view. Shown is a section with several consecutive chain links of the conveyor chain 150 in connecting devices 40 inserted and attached to it. The connecting devices 40 are at the bottom of the transport towers 1 trained and installed. Every transport attachment 1 has in the illustrated embodiment exactly such a connection device 40 on, on at least one chain link of the conveyor chain 150 is attached. Here are the connecting devices 40 a greater lateral extent than the chain links of the conveyor chain 150 ,

In the context of the invention, the extent transverse and / or perpendicular to the conveying direction is always referred to as lateral extent, ie a direction perpendicular to the driven guiding direction of the driven conveyor chain 150 , At the same time, the lateral direction is a substantially horizontal direction.

Each of the connecting devices 40 has at least a curve inside a lateral support surface 41 on. The lateral support surfaces 41 the transport attachments 1 together form a rolling surface for the statically fixed lateral support rollers 130 ready. As in 2C shown, roll the static lateral support rollers 130 not directly on the conveyor chain 150 and thus do not wear out the conveyor chain directly 150 , Rather wear when then the lateral support surfaces 41 which is easier than the conveyor chain 150 interchangeable, eg by acceptance and / or replacement of the transport attachment 1 , Replacing the transport attachment 1 is also easier than replacing one or more chain links of the conveyor chain 150 because when replacing one of the transport attachments 1 the conveyor chain 150 does not have to be opened.

In curve guide, the lateral support surfaces 41 one under the transport plate 50 arranged, contiguous, after the curve inside plate end directed rolling surface ready. At the lateral support surfaces 41 , in particular at the ends of the support surface 41 in and against the conveying direction, projections and / or recesses may be formed, resulting in a partial overlap of adjacent lateral support surfaces 41 to lead. This is below in particular in connection with the 6A to 6E described in more detail.

The lateral support surfaces 41 adjacent connecting devices 40 can be so close together along the conveyor chain 150 be arranged that they touch and / or overlap at least in curve guide on the inside of the curve. As a result, at least in curve guide the curve center or the helical axis W facing, contiguous rolling surface for the statically fixed lateral support rollers 130 provided, which is formed substantially gap-free.

This rolling surface, that of the lateral support surfaces 41 the individual transport attachments 1 is provided, is formed substantially along the conveying direction - but slightly offset to the curve center - and along a vertical direction.

Also in 2C shown are some of the free support areas 31 as well as a occupied support place 31 on which a carrying role 30 is arranged.

3 shows in a perspective view parts of the second plate conveyor 200 , The 3 shows a similar section as for example 2A , only in a perspective view. At one end of the rectilinear course of the plate conveyor 200 is shown as the transport attachments 1 be folded down to return the conveyor chain 150 below the conveying surface 140 , As in the 2A and 2 B are also in 3 Railway boundaries, side guides and / or web surfaces, etc. not shown. These elements of the second plate conveyor 200 may be similar or identical to those of the 1 A to 1D shown first plate conveyor 100 be educated.

4 shows a perspective view of a section of the second plate conveyor 200 without driven conveyor chain 150 but with some elements of the track surface 125 , above which the driven conveyor chain 150 to be led. This is especially a part of the track area 125 shown, which is arranged in a substantially horizontal plane. The railway area 125 is essentially parallel to the conveying surface 140 arranged below this and formed approximately the same size. The railway area 125 defines the conveyor of the plate conveyor 100 or. 200 and can be used to unroll and support the idlers 30 serve on the bottom 20 the transport attachments 1 are arranged and the weight of the transport essays 1 , the floating conveyor chain 150 and / or the subsidized goods carry.

Approximately in the middle under a transport plate 50 the transport attachments 1 is the connection device 40 shown which the lateral support surface 41 has as a rolling surface for the lateral support rollers 130 , The lateral support rollers 130 can on and / or on the track area 125 be attached, for example by means of a screw and / or welded joint.

The conveyor chain 150 is in 4 not shown, which is a view of an internal cavity in the connecting device 40 allows. This cavity can act as a traction mechanism for the conveyor chain 150 be educated. Inside the connection device 40 is at least one fastener 42 provided, which may be formed, for example, as a clip for clipping to the conveyor chain 150 , in particular to a chain link of the conveyor chain 150 , A clip connection allows a simple to produce and easy to be solved positive connection of the transport attachment 1 with the conveyor chain 150 , Instead of a conveyor chain 150 For example, another drawing medium such as a steel cord and / or a rubber block chain may be used.

The center axis of the conveyor chain 150 can be located lower in the operating position than the center of the statically fixed lateral support rollers 130 , As a result, a tilting moment and thus a contact pressure of the transport attachments 1 including traction means in the direction of the web surface 125 be generated and thus unintentional lifting the transport attachments 1 be prevented.

The transport surfaces 10 are in operating position below the side guides 120 arranged, which is a lifting of the transport essays 1 from the railway area 125 under the action of a one-sided external force, for example, by a one-sided on the transport surface 10 prevent and / or reduce the position of conveyed material or foreign objects. The transport surfaces 10 are in operating position so below the side guides 120 arranged and / or spaced from that without the action of a one-sided external force on the transport surface 10 the side guides 120 essentially not be touched to minimize friction, wear and noise. Thus, they contribute to the floating guidance of the conveyor chain 150 at. The railway area 125 , the side guides 120 and the lateral support rollers 130 provide statically fixed elements of the plate conveyor 100 or. 200 represents.

5A shows a view from above on the transport plate 50 one of the transport attachments 1 according to an embodiment. The top view provides a view of the transport surface 10 the transport plate 50 , The transport surface 10 is aligned in the operating position so that it points away from the traction means.

The transport plate 50 has a plurality of damping means 500 on which the transport plate 50 completely off the transport surface 10 to the bottom 20 penetrate. At the transport surface 10 protrude areas of the damping means 500 as detention areas 510 from the transport surface 10 out. These adhesive areas 510 Prevent and / or reduce slippage of conveyed goods on the transport plates 50 , This can in particular in a promotion along a slope (such as in the first plate conveyor 100 ) be advantageous. The detention areas 510 can eg as elastomeric elements and / or rubbers 51 be educated. In the embodiment shown is a plurality of damping means 500 per transport plate 50 provided, in particular four damping means 500 each with a detention area 510 , which has an elongated formation in lateral extension transversely to the conveying direction.

The damping means 500 can be designed as a sprue. The damping means 500 can by means of a two-component injection molding process in the transport surface 10 be introduced.

At a front in the conveying direction plate end 54 the transport plate 50 is the transport plate 50 formed lowered over a step. This will be at the front plate end 54 a lower step as a sinking surface 56 provided. The sinking area 56 is opposite a rear plate end 55 formed lowered and can under a similar transport plate 50 a preceding transport direction in the conveying direction 1 intervention. This will cause an overlap of successive transport plates 50 allowing, in turn, a substantially gap-free conveying surface 140 is possible.

At the rear end seen in the conveying direction 55 is an upper level as an elevation 57 trained (cf. 5D) , under which in operating position the sinker 56 the transport plate 50 a subsequent transport attachment 1 can be arranged. The assessment 57 forms a part of the conveying surface of the plate conveyor 100 . 200 out.

The transport plate 50 is formed asymmetrically at least in top and bottom view. Although the upper stage of the transport plate 50 which the transport surface 10 training (ie the survey 57 ), be formed substantially symmetrically, for example in the form of an arrowhead (as in 5A shown).

However, at least the sinking 56 be formed asymmetrically.

The transport plate 50 points at a laterally inside plate end 52 a smaller width in the conveying direction than at a laterally outside plate end 53 , This creates an asymmetrical design of the transport plate 50 , The inside plate end 52 is lateral to a central region of the transport plate 50 spaced and in the curve guide of the plate conveyor 100 or. 200 the curve center or the helix axis W facing. The outside plate end 53 is also lateral to the central region of the transport plate 50 spaced and is in curve guide from the center of the curve or the helical axis W away.

Due to the reduced width of the transport plate 50 at the inside of the curve 52 can be consecutive transport plates 50 easier nested one above the other, as for example on the inside of the curve in 3 and 2A is shown. At the outer end of the plate 53 has the transport plate 50 a greater width, which prevents the formation of gaps even on the outside of the curve, cf. to that too 3 and 2A ,

In the illustrated embodiment, the entire outside of the curve wing of the transport plate 50 a substantially constant width, from a central region of the transport plate 50 to the outer end of the plate 53 , On the curve inside wing of the transport plate 50 takes the width in the conveying direction of the inside plate end 52 up to the middle area of the transport plate 50 essentially steadily too. This asymmetric design, in particular the sinker 56 allows a particularly efficient and gap-free curve guidance.

5B shows in a side view opposite to the conveying direction, the transport plate 50 , The detention areas 510 the damping means 500 protrude slightly over the transport surface 10 out, which can reduce slipping of conveyed goods. Overall, the transport plate 50 essentially formed as a flat plate whose thickness is significantly lower, for example at least 80%, preferably at least 90% less than their lateral width and / or their width is formed in the conveying direction.

5C shows a view from below of the transport plate 50 , Shown in particular is the bottom 20 the transport plate 50 with a plurality of support stations 31 (here, for example, six pieces), to each of which a carrying role 30 can be arranged. Both on the inside wing and on the outside wing of the transport plate 50 For example, there are three support places each 31 educated. In the middle of the bottom 20 the transport plate 50 is a substantially rectangular central area 58 formed, on which the connecting device 40 can be attached. The middle area 58 divides the transport plate 50 essentially in the middle of two wings. The middle area 58 can thereby mark the beginning of the inside wing, which extends to the inside plate end 52 extends, as well as the beginning of the outside plate wing, which extends to the outside plate end 53 extends.

5C further shows a plurality of attenuation regions 520 in the embodiment shown, for example, three attenuation ranges 520 per wing of the transport plate 50 So, for example, a total of six attenuation ranges 520 , Each of the damping areas 520 sticks out at the bottom 20 from the transport plate 50 out. Each of the attenuation ranges 520 in the in 5C view formed from below as an approximately circular area. Each damping area 520 forms a kind of "damping mushroom", from which a part of the "mushroom hat" down from the transport plate 50 protrudes.

All attenuation ranges 520 are at the survey 57 the step-shaped transport plate 50 trained (cf. 5D) So, from the elevated level, stand down from the transport plate 50 out. In addition, all attenuation ranges are here 520 at positions at the bottom 20 the transport plate 50 formed between the support areas 31 the idlers 30 and either the front or back plate end 54 . 55 are arranged - in the embodiment shown, the rear plate end 55 ,

On each wing of the transport plate 50 are each two of the attenuation ranges 520 as centrally arranged damping areas 521 trained and a damping area 520 as end-mounted damping area 522 , Here is the end-mounted damping area 522 arranged near the respective end of the wing, so near the inside or outside plate end 52 . 53 , More precisely, the end-mounted damping region 522 in the lateral direction between the respective laterally outermost supporting place 31 and the respective lateral plate end 52 . 53 arranged.

The two centrally located damping areas 521 are arranged approximately in the middle of the wing, that is approximately in the middle between the center of the transport plate 50 (where also the middle area 58 is arranged) and the respective lateral plate end 52 . 53 , In the illustrated embodiment with the three support stations 31 are the two centrally located damping areas 521 adjacent to each middle support place 31 the respective wing of the transport plate 50 arranged.

The damping ranges 520 show off the bottom 20 out down, taking about 0.1mm from the bottom 20 stand out. The damping ranges 520 serve for damping, in particular for noise reduction during operation of the plate conveyor 100 and 200 , Here, the attenuation ranges 520 Bumps between the transport plate 50 and one under the survey 57 engaging, subsequent transport plate 50 of the plate conveyor 100 . 200 cushion, in particular shocks in an approximately vertical direction. A substantially identical, subsequent transport plate 50 can with her sinking 56 under the survey 57 the preceding transport plate 50 intervention. Here are the damping ranges 520 the preceding transport plate 50 in approximately vertical direction between the (lowered) transport surface 10 the following transport plate 50 and the raised bottom 20 the preceding transport plate 50 arranged.

The damping ranges 520 are integrally formed of the same elastic material as the damping means 500 , So for example made of an elastomer and / or rubber. This allows the damping areas 520 a damping in the vertical direction.

5C also shows two buffer areas 530 , each of which has a buffer area 530 on each of the two wings of the transport plate 50 is arranged. At each wing is the buffer area 530 at that support place 31 arranged, which is either closest to the front plate end 54 or closest to the back of the plate 55 is arranged, depending on which end of the plate 54 . 55 the assessment 57 is trained. In the illustrated embodiment, the survey 57 at the rear end of the plate 55 formed, which is why the buffer area 530 at the support place 31 is arranged, which closest to the rear plate end 55 is arranged.

At each wing is the buffer area 530 at the laterally outermost supporting place 31 arranged, so the support point 31 which closest to the respective lateral plate end 52 or 53 is arranged.

From the support place 31 off is the buffer area 530 the plate end (in or against the guide direction) facing, under which the adjacent transport plate 50 the respective transport plate 50 engages below. In the embodiment shown, the buffer area 530 so at the support area 31 arranged that he is against the guiding direction to the rear plate end 55 has. Specifically, a normal points to the buffer area 530 to the rear end of the plate 55 ,

The buffer area 530 is essentially flat at the stage of the transport plate 50 trained, so at the transition from the survey 57 to the sinking area 56 , The buffer area 530 protrudes in a substantially horizontal direction from the bottom 20 the transport plate 50 out, in the embodiment shown opposite to the guide direction to the rear plate end 55 out. The buffer area 530 forms a buffer zone in or against the guide direction, ie approximately parallel to the direction of traction, here the conveyor chain 150 , That's why the in 5C shown buffer areas 530 shown in the view shown from below only as narrow slits.

The buffer areas 530 show off the bottom 20 out to the rear, taking about 0.1mm to about 0.2mm from the bottom 20 towards the rear end of the plate 55 stand out. The buffer areas 530 also serve for damping, in particular for noise reduction during operation of the plate conveyor 100 and 200 , Here, the buffer areas 530 Bumps between the transport plate 50 and one under the survey 57 engaging subsequent transport plate 50 of the plate conveyor 100 . 200 cushion, in particular impacts in an approximately horizontal direction parallel to the conveying direction. A substantially identical, subsequent transport plate 50 can with her sinking 56 under the survey 57 the preceding transport plate 50 intervention. Here, the following transport plate 50 the previous transport plate 50 to the rearmost support places 31 Under attack and at this rearmost support areas 31 butt (in the embodiment shown, the two laterally outermost support sites 31 ). Here are the buffer areas 530 the preceding transport plate 50 approximately in the horizontal direction between the two transport plates 50 arranged.

The buffer areas 530 are integrally formed of the same elastic material as the damping means 500 , This allows the buffer areas 530 a damping in the horizontal direction (approximately parallel to the conveying direction).

In 5C five different lines are marked with the letters AA, BB, CC, DD and EE. Cross sections along these five lines are in the 5F to 5J shown.

5D shows in a side view in this view almost (mirrored) Z-shaped transport plate 50 , It is at the front plate end 54 the sinking area 56 shown as lower step, which is below the elevation 57 as upper step on rear plate end 55 one at the front of the conveyor chain 150 arranged structurally identical transport attachment 1 can be introduced. As a result, a (vertical) overlap of the transport plates 50 be enabled. The stepped formation in the side view of the transport plate 50 is in 5D shown. Only in the middle range 58 the stepped design can either be omitted entirely or shortened. At this middle area 58 becomes the conveyor chain 150 attached, so here is a nearly constant distance between successive transport plates 50 can be fixed. At the rear end of the plate 55 is the elevation 57 beveled so formed that the (vertical) thickness of the transport plate 50 decreases towards the back.

5E shows the transport plate 50 in a view in the conveying direction, ie "from behind". It is in 5E shown how the damping areas 520 down from the bottom 20 the transport plate 50 stand out, especially from the survey 57 the transport plate 50 ,

In 5E are still the abutment areas 31 shown as well as the buffer areas 530 , whose rectangular surface in this view points to the rear and thus out of the plane of the drawing.

5F shows in a sectional view along in 5C marked line AA the transport plate 50 a transport attachment 1 of the plate conveyor 100 ; 200 , In the view shown is the transport surface 10 shown above while the bottom 20 shown below. The cross section goes through the survey 57 the transport plate 50 at a position where a damping means 500 is trained. The damping agent 500 forms at the transport surface 10 the (laterally) elongated adhesive area 510 off and at the bottom 20 the damping area 520 , The damping agent 500 is formed in one piece. Here is the detention area 510 with the damping area 520 via at least one connecting channel 540 connected. The cross section AA even goes through two connection channels 540 , The connection channels 540 penetrate the transport plate 50 , more precisely, the survey 57 the transport plate 50 , in a vertical direction. The (horizontal) extension of the connection channels 540 is much smaller than the (horizontal) extent of the damping range 520 and especially the detention area 510 ,

Specifically, the largest (horizontal) extent of the connection channels 540 no more than 20% of the largest (horizontal) extension of the attenuation range 520 , preferably at most 10%.

Each damping area 520 can with at least one adhesive area 510 via a plurality of connecting channels 540 be connected, for example, over two, three, four or more such connection channels 540 , The connection channels 540 allow all elements and / or components of the damping means 500 Made in one piece. In the illustrated embodiment, the two centrally located damping regions 521 via connection channels 540 with different adhesive areas 510 connected.

5F shows a section through the maximum lateral extent of the damping region 520 , as a cross section through the center of the damping region 520 ,

The 5F and 5G each show a cross section along the in 5C marked lines CC and DD through the damping means 500 the transport plate 50 at (in the conveying direction) outer positions of the damping region 520 , This shows 5G a cross section at a rather rear position through the damping area 520 , while 5H a cross-section at a more forward position through the damping area 520 shows. It is especially in 5G the (inverse) "mushroom" shape of the damping area 520 shown.

In each of the in the 5G and 5H shown cross sections is each a connecting channel 540 shown, which by the transport plate 50 goes through and the elements of the damping means 500 combines.

In the illustrated embodiment, the end-mounted damping region 521 integral with the same damping means 500 formed, with the one of the centrally located damping areas 521 is integrally formed. This is the (eg in the 5A and 5B shown) laterally outer damping means 500 ,

The other one (in 5H shown) centrally arranged damping region 521 is integral with the laterally inner damping means 500 educated.

This applies to each of the two wings of the transport plate 50 ,

51 shows in a sectional view along in 5C marked line B - B a buffer area 530 the transport plate 50 , The cross section goes through the survey 57 the transport plate 50 at a position where one of the damping means 500 is trained. The damping agent 500 forms at the transport surface 10 the (laterally) elongated adhesive area 510 off and at the bottom 20 the buffer area 530 , The damping agent 500 is formed in one piece. Here is the detention area 510 with the buffer area 530 via at least one buffer channel 545 connected. The at least one buffer channel 545 penetrates the transport plate 50 , more precisely, the survey 57 the transport plate 50 , in a vertical direction. The (horizontal) extent of the buffer channel 545 is much smaller than the (horizontal) extent of the buffer area 530 and especially the detention area 510 , Specifically, the largest (horizontal) extent of the buffer channel 545 no more than 20% of the largest (horizontal) extent of the buffer area 530 , preferably at most 10%.

Each buffer area 530 can with at least one adhesive area 510 via a plurality of buffer channels 545 be connected, for example, two, three, four or more such buffer channels 545 , The buffer channels 545 allow it, all elements of the damping means 500 Made in one piece.

In the embodiment shown, the buffer area 530 integral with the same damping means 500 designed, with the end of the arranged damping area 521 and one of the centrally located damping regions 521 are integrally formed. This is the (eg in the 5A and 5B shown) laterally outer damping means 500 ,

5J shows in a sectional view along in 5C marked line EE a damping means 500 the transport plate 50 , Here, the laterally inner damping means 500 shown the middle area 58 partially overlapped, on which the connecting device 40 can be attached.

As in 5J shown penetrates the damping means 500 the transport plate 50 at the position of the central area 58 Not. In 5J is just a depression 501 of the damping agent 500 shown which the compound of the damping agent 500 with the transport plate 50 strengthened.

The compound of damping agents 500 with the transport plate 50 is (except due to the depression 501 ) Also because of this stable, since all adhesive areas 510 from the transport surface 10 through the transport plate 50 through with a damping element at the bottom 20 the transport plate 50 are connected, so with at least one damping range 520 and possibly a buffer area 530 ,

This applies to both wings of the transport plate 50 ,

6A to 6E show the connection device 40 of the transport attachment 1 according to the embodiment in different representations. 6A shows a view against the conveying direction of the connecting device 40 . 6B a cut along in 6A drawn plane B - B . 6C a side view, 6D a view from below and 6E a view from above of the connecting device 40 ,

The connection device 40 has a Zugmittelaufnahme 48 on, which is designed as a recess and for receiving the conveyor chain 150 is provided. The Zugmittelaufnahme 48 is elongated in the conveying direction. The connection device 40 may be substantially clamp-shaped and / or C-shaped around the Zugmittelaufnahme 48 be educated. At lateral, the Zugmittelaufnahme 48 facing inner sides of the connecting device 40 are fasteners 42 formed, in the at least one chain link of the conveyor chain 150 at least partially clipped.

Alternatively, another attachment with the conveyor chain 150 be provided. However, the attachment is preferably at least form-fitting, to no slippage between the driven conveyor chain 150 and the transport attachments 1 permit. On lateral outer surfaces of the connecting device 40 are the lateral support surfaces 41 trained (see, for example 6A) , Above and below the lateral support surfaces 41 is each an upper projection 46 as well as a lower lead 45 educated. These projections can with the lateral support rollers 130 and or the chain guides 121 . 122 so cooperate that a guide of the transport attachments 1 and thus the conveyor chain 150 is provided in the vertical direction and / or lifting the transport essays 1 and thus the conveyor chain 150 is limited.

Through the lower projection 45 below the lateral support surface 41 a lift-off protection is provided, in addition to the side guides 120 A particularly efficient lift-off protection for the transport attachments 1 can allow.

As in particular in 6C shown has the lateral support surface 41 at a front surface end seen in the conveying direction 43 a projection on and at a rear end seen in the conveying direction 44 a recess. The rounded projection on the front surface end 43 is essentially complementary to the rounded recess at the rear surface end 44 designed so that successive connecting devices 40 can overlap each other at the front and rear surface ends.

This overlap of the lateral support surfaces 41 is for example also in 2C shown in which the connecting devices 40 are shown in a horizontal section.

6D shows that the connecting device 40 four fasteners 42 each of which has two laterally opposite to the Zugmittelaufnahme 48 are formed. In each case two opposite fastening means 42 a pin and / or bolt of a chain link can be clipped. Thus, in the connecting device 40 two transverse pins or transverse pins of the conveyor chain 150 be completely absorbed and attached, which belong for example to a single chain link.

This can be any fastener 42 have at least one substantially circular recess with a pointing away from the Zugmittelaufnahme lateral depth, see. this also the sectional view of 6B , The inner diameter of the circular recesses may be on the outer diameter of the transverse pins of the conveyor chain 150 be adapted, so for example complementary to it (with or without game) be formed. The fasteners 42 may have a vertically elongate body, of which the transport plate 50 facing (ie upper in operating position) end is rigid and their transport plate 50 remote (ie in the operating position lower) end is formed resilient in the lateral direction.

The fasteners 42 can be used to engage the conveyor chain 150 be educated. For this, the conveyor chain 150 have extended bolts that are lateral to the conveyor chain 150 protrude. In this case, for example, the bolts can protrude beyond the respective chain link by at least 10% of the lateral extent of the conveyor chain. As a result, a particularly favorable latching and / or fastening to the fastening means 42 allows.

6E shows a view from above of the connecting device 40 , Here protrude the front surface ends 43 over the rest of the connection device 40 in the conveying direction. On the surface of the connecting device 40 is a plurality of attachment points 47 trained, for example, four attachment points 47 , At the attachment points 47 can the connection device 40 with the transport plate 50 be connected, in particular with the central area 58 the transport plate 50 , The connection device 40 can with its surface at the bottom 20 the transport plate 50 be attached and / or be, in particular welded to it, so that there is a cohesive connection, which is insoluble without destruction.

As a conveyor chain 150 In particular, a side arc chain can be used, for example with extended (transverse) bolts. The extended bolts can be attached to the connector 40 simplify. A side arc chain allows bending and thus a simplified curve guide without or with reduced risk of blockage of the chain.

The connection device 40 and / or the carrying rollers 30 can, for example, by means of ultrasonic welding to the transport plate 50 be attached. This provides a particularly easy-to-implement and a particularly stable material-strength connection type.
