Description

The present invention relates to a lifting device for a handling and / or palletizing, with a lifting column, which has a vertical guide for a motor on a column side via a rolling bearing vertically movable lifting.

In the area of beverage production or filling and packaging technology, beverage containers are combined into containers consisting of several combined beverage containers, and these containers are subsequently assembled into palletisable bundle layers and stacked in layers on pallets. For this purpose, the containers or containers go through different conveyor stations. In order to stack or palletize these full length package layers, there are a variety of devices commonly known as palletizers. Such palletizers usually consist of a hoist and a handling device arranged thereon, such as a lifting device. a loading station, Beladegreifer, loading plate, Jalousiegreiferkopf or the like. In conventional palletizing the hoists consist of at least one Hubwerksäule, which may be formed by a tubular or shaft-shaped column and arranged on one side of vertical guides. Within the tubular or shaft-shaped column, the cavity provides sufficient space for a counterweight, which stands by means of a belt and a driven pulley in conjunction with the on one side of the hoist on the guides vertically movably mounted loading station or handling device. In these devices are fast strokes within a defined range of motion in the foreground, which should run as accurately as possible and trouble-free. The vertically moving hoists are usually operated by electric motor and are usually roller bearings in the interest of a smooth vertical mobility.

Similar to the palletizing device just described, it is, for example, also in a so-called intermediate layer inserter. An intermediate layer inserter is used to place an intermediate layer between the individual stacked package layers, which is usually formed by a flat blank made of cardboard. This is done in an alternating manner, so that after each layer of containers an intermediate layer can be placed. This liner insert is almost identical to the basic structure as the palletizer described above. However, instead of a loading plate or loading station, a gripping arm or a similar handling device is mounted, which has arranged at one end suitable gripping means for receiving or gripping of intermediate layers. If we speak of the same construction, this refers to the basic structure, but not the other construction details, which of course may differ in the dimensions of each other. Most of the liner insert has the same components as tubular or shaft-shaped column, guides, counterweight, welded or bolted base plate, motor drive, belt or timing belt, connecting lines (pneumatic, electric) and a handling device. Both devices also require smooth running and over the longest possible service life trouble-free rolling bearings or Wälzpaarungen for the vertical mobility of the lifting or handling and / or Palettiereinrichtungen.

These Wälzpaarungen showed in the past practice sometimes problems, because on the one hand very accurately installed and must be adjusted with relatively high effort. Nevertheless, often occur in storage disorders, which can lead to high maintenance.

A primary object of the present invention is thus to provide a lifting device, e.g. for a palletizing and / or Zwischenlageneinlegevorrichtung or for partially or fully automatic packing and / or sorting machines to provide that includes a Hubwerksäule with vertically movable lifting carriage, which is as simple and stable as possible, easily moving and possible Robust and trouble-free working vertical suspension and guide is connected to the lifting column.

This object is achieved with the subject matter of independent claim 1. Features of advantageous developments of the invention can be found in the dependent claims. Thus, in order to achieve the object, the invention proposes a lifting device with the features of claim 1 for a handling and / or palletizing device or the like, which in particular may be part of a packaging line. The lifting device according to the invention comprises as an essential support element a Hubwerksäule which has a vertical guide for a motor on a column side via a roller bearing with at least three rolling elements vertically movable lifting a handling, conveying, stacking and / or gripping element, in particular for handling Articles, piece goods, containers o. The like. Wears. The rolling elements are each formed by rollers which are rotatably mounted on the vertically movable lifting carriage about horizontal axes. The rollers roll with their respective peripheral sides on guide rails, which are anchored to the Hubwerksäule and along at least one column side in the vertical direction extend. According to the invention, the rollers each have profilings on their outer peripheries that correspond to the cross-sectional contours of the guide rails. In addition, the lifting slide is kinematically determined by the rolling bearing in its suspension. Both the rollers which form the rolling elements and the guide rails on which the rollers roll, are preferably made of metal, in particular of steel, so that a stable and low-wear rolling and friction pairing results which the desired operating characteristics for trouble-free Continuous operation supplies.

It should be noted that the present invention will be described below by way of example by a palletizer. However, this is not meant to be limiting in any way that the invention can only refer to a palletizer. The invention is equally applicable to any apparatus which has the same or approximately the same basic structure as a palletizer described below. Thus, the invention can also be applied to an intermediate layer inserter which has the same basic structures or components.

The lifting device according to the invention with the supporting Hubwerksäule may comprise a rolling bearing with at least four respective rolling elements formed by rollers and preferably at least two guide rails, wherein each two rolling elements cooperate with a guide rail for forming a Wälzpaarung. In order to safely carry the lifting and to be able to lead vertically, two roles of rolling bearings are usefully mounted rotatably on a common horizontal height level on the lifting carriage. In addition, it is useful for a loadable with high loads suspension and guidance of the lifting, if the at least one upper roller is supported with respect to the lifting back of one of the at least two guide rails. In addition, it is useful if the at least one lower roller is supported on one of the at least two guide rails in front of the lifting carriage.

Since normally at least two rollers are used for the upper guide and two other rollers for the lower guide, it makes sense if the two at a common first height level and horizontally spaced lower rollers with respect to the lifting on the front of the two supporting parallel in vertically oriented guide rails, and wherein the two are supported at a common second height level, which is located above the first height level with the lower rollers, and horizontally spaced upper rollers with respect to the lifting back of the two guide rails , By this back and front guides of the respective pairs of rollers optimal load support of the load bearing with high lifting capacity is ensured. At the same time, the rollers, in conjunction with the guide rails, ensure a wear-resistant and load-bearing rolling bearing of the vertically adjustable lifting carriage, so that the above-mentioned aim of the invention can thus be implemented in an optimum manner.

The guide rails can in particular be formed in each case by steel strips with a rectangular cross-section, which are also preferably anchored flat and / or a plurality of fixing points on the lifting column, so that they are subject to any elastic deformation, even when subjected to high load lifting.

According to a preferred embodiment of the lifting device or the lifting column, the rollers which form the rolling elements may each have outer running surfaces with a V-shaped notched cross-section. These notches in the outer running surface of the rollers can be formed in particular by 90 ° notches in cross section, which allow an approximately positive rolling of the rollers on the correspondingly contoured guide rails. Thus, each roll with its V-shaped notched cross section preferably roll on one of the outer edges of the rectangular guide rails. Since the guide rails preferably have edges with a 90 ° cross section, where the corresponding notched rollers can sit there and roll off, whereby not only a longitudinal guide for the roles, but equally a transverse guide is given, which forces the rollers in an exact vertical path and which is able to absorb relatively high lateral forces, which may occur, for example, by an uneven or changing load of the lifting or in particular by a transversely projecting lifting. Since the lifting slide may, depending on the structural design, have a transverse traverse with a relatively wide boom area, uneven transverse forces can act on the rolling bearing of the lifting carriage, which can be accommodated in an ideal manner by the roller design, which is adapted to the contouring of the guide rails.

Some of the rollers may have lubrication to increase long-term stability and reduce wear on the pair of gears. Preferably, at least the upper rollers with a permanent or loss lubrication assigned a friction-reducing lubricant, so that the lower rollers can be supplied by distributed lubricant. Such lubrication of Wälzpaarungen is useful in many materials used, especially in the preferably used steel pairings of roles and the guide rails.

In addition to the above-mentioned variant of the profiling of the rollers with their V-shaped notched outer running surfaces, an alternative variant can also provide a kinematic reversal of the contours of the rollers and the rails or their profiles. Thus, for example, according to an alternative embodiment variant of the lifting device or the lifting column, the rollers which form the rolling elements each have outer running surfaces with a roof-shaped profiled cross-section. These roof-shaped or triangular formations in the outer running surfaces of the rollers can be formed in particular by 90 ° elevations or 90 ° -points in cross-section, which allow an approximately positive rolling of the rollers on the correspondingly contoured guide rails. Thus, each roll with its V-shaped cross section preferably roll on a correspondingly shaped groove or vertically extending notch of the guide rails. Since the guide rails also preferably have notches or longitudinal grooves with a triangular 90 ° cross section, the correspondingly shaped rollers can be picked up there and guided there exactly guided, whereby not only a longitudinal guide for the roles, but equally a transverse guide is given, which the rollers in an exact vertical path forces and which is able to absorb relatively high lateral forces, for example. By uneven or changing load of the lifting or in particular by a transverse projecting lifting can occur. Thus, uneven lateral forces can be accommodated by the role design, which is the contouring of the guide rails, even in this alternative embodiment of the rolling bearing in an ideal manner.

Also, mixed variants are conceivable in which, for example, the upper (or lower rollers) have the above-mentioned V-shaped notches, while the lower rollers (or the upper) rollers may have the triangular or roof-shaped notches described in the alternative embodiment wherein the upper and lower rollers each have to roll on different areas of the guide rails assigned to them, wherein these different areas each have the mating surfaces or counter contours corresponding to the rollers.

It should be noted at this point that the present invention in addition to the lifting device described above in various embodiments also includes a Hubwerksäule with it vertically guided and motorized lifting, in which the vertically movable lifting a roller bearing with at least three rolling elements formed by rolling on Guide rails held and guided. This lifting column is in particular part of a lifting device according to one of the embodiments described above.

For identical or equivalent elements of the invention, identical reference numerals are used. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are only examples of how the lifting device according to the invention can be configured and do not represent a final limitation.

The 1 to 6 show in various schematic detail views of an embodiment of a lifting device according to the invention 10 , which may be in particular part of a packaging line not shown here in detail. Within this packaging line, the lifting device 10 be arranged as part of a handling and / or palletizing. The essential Task of this lifting device 10 exists in the context of such a packaging line in lifting, receiving and / or discontinuation of piece goods, in particular stackable layers of piece goods, or in the handling of liners or the like flat objects that can be placed, for example. Between stacked piece goods. The only partially shown lifting device 10 includes as an essential support element a Hubwerksäule 12 holding a vertical guide 14 for a motor on a column side 16 via a roller bearing 18 with at least three rolling elements 20 vertically movable lifting carriage 22 which can carry a handling, conveying, stacking and / or gripping element, in particular for handling articles, piece goods, containers or the like. In the illustrated embodiment of the 1 to 3 . 5 and 6 is at the vertical in the direction of the arrow 24 adjustable lifting carriage 22 one horizontally from the front pillar side 16 cantilevered handling element 26 anchored, for example, by a Jalousiegreiferkopf, a vertically adjustable Überubfläche o. The like. May be formed. The handling element 26 can optionally also be formed by a suitable gripping device for receiving and handling of flat intermediate layers or other elements.

The rolling elements 20 that the lifting slide 22 in vertical direction in the direction of the arrow 24 adjustable way with the lifting column 12 connect, are each by roles 28 formed on the vertically movable lifting 22 around horizontal axes 30 are rotatably mounted. As in particular the detailed view of the 1 recognize, are the roles 28 on the lifting carriage 22 rotatably mounted, wherein the axes of rotation 30 are aligned horizontally so that the rollers 28 each within vertical planes (not shown) rotate.

The four roles 28 roll with their respective peripheral sides on two guide rails 32 from the lifting column 12 are anchored and along the front column side 16 extend in the vertical direction. The two guide rails 32 are located on the lateral vertical edges of the front column side 16 so every guide rail 32 as sliding guide for every two rolls 28 can serve. As the detailed plan view of the 4 with the rolling bearing 18 and a rolling element exemplified 20 clearly indicates the roles 28 at their outer peripheries 34 each profiling 36 on, with the rectangular cross-sectional contours 38 the guide rails 32 correspond. The 4 also allows the special design of the outer treads 34 the roles 28 recognize, which provides a V-shaped notched cross-section in the illustrated embodiment. These notches 40 in the outer tread 34 the roles 28 have according to the embodiment shown a flank angle of about 90 °, so that in connection with the rectangular cross-sections 38 the guide rails 32 an approximately positive rolling of the rollers 28 on the correspondingly contoured guide rails 32 is guaranteed. Thus, every role rolls 28 with its V-shaped notched cross-section 40 exactly on one of the outer edges 42 the rectangular guide rail 32 from. As well as the guide rails 32 each edges 42 With a 90 ° angle, there can be the corresponding notched rollers 28 each sit and roll, making not only a longitudinal guide for the roles 28 but equally a lateral guidance is given which the roles 28 forces into an exact vertical path and which is able to absorb relatively high lateral forces, for example, by an uneven or changing load on the lifting 22 or in particular by a transversely projecting handling device 26 on the lifting carriage 22 (see. 1 and 3 ) can occur. Because of the lifting carriage 22 Depending on the structural design may have a cross-beam with relatively wide boom area, can on the rolling bearing 18 of the lifting carriage 22 uneven lateral forces act by the role design, the contouring of the guide rails 32 adapted, can be recorded in an ideal way.

As the detail view of the 4 can recognize the vertical outer edges 42 the guide rails 32 each have a chamfer, in particular with a corresponding basic contour of the V-shaped notched cross-section 40 the roller tread 34 can correspond, which can be easier to realize production technology than an exactly V-shaped contour of the roller tread 34 with a pointed notch bottom. Both the roles 28 which the rolling elements 20 form, as well as the guide rails 32 on which the roles 28 roll and together with them the rolling bearing 18 are preferably made of metal, in particular made of steel, so that there is a stable and low-wear rolling and friction pairing, which can provide the desired operating characteristics for trouble-free continuous operation. The guide rails 32 In addition, they can preferably be flat and / or have a multiplicity of fixing points or screw connections 52 on the lifting column 12 be anchored (cf 6 ), so that they are as possible no elastic deformations subject, even when subjected to high load Hubschlitten 22 ,

As the schematic and perspective detail views of 2 and 3 clearly indicate, is the lifting 22 through the rolling bearing 18 in its suspension and vertical guidance 14 as well as the vertical mobility in stroke direction 24 determined kinematic and clearly defined. The lifting device exemplified 10 with the supporting lifting column 12 includes a rolling bearing 18 with a total of four each by rollers 28 formed rolling elements 20 and two vertically extending, parallel to the front pillar side 16 (not recognizable in the 2 and 3 ) arranged guide rails 32 , wherein in each case two rolling elements 20 or roles 28 with one of the two guide rails 32 cooperate to form the respective Wälzpaarung. To the lifting carriage 22 To be able to carry safely and lead vertically, there are two roles 28 the rolling bearing 18 on a common horizontal height level 44 respectively. 46 on the lifting carriage 22 rotatably mounted. This first height level 44 the two lower rollers 28 and the second height level 46 the two upper rollers 28 the rolling bearing 18 are in the 1 and 2 each indicated by broken lines, each on a level with the axes of rotation 30 the roles 28 lie.

The perspective view of the 2 leaves from the lifting column 12 only the right side surface 48 recognize while the front pillar side 16 at which the lifting carriage 22 in the vertical direction of movement 24 is raised and lowered, is covered. However, as this view reveals very well, the upper rollers are based 28 of the upper second height level 46 in relation to the lifting carriage 22 at the back of the respective guide rails 32 what, for the high loads can be acted upon suspension and guidance of the lifting 22 makes sense while the two lower rollers 28 of the lower first height level 44 in relation to the lifting carriage 22 front on the two guide rails 32 support. That is, each of the four roles 28 the rolling bearing 18 runs on its own outer edges 42 the with rectangular cross-section 38 equipped guide rails 32 (cf 4 ). From each of the two guide rails 32 Thus, only the two serve with respect to the front column side 16 outer edges 42 as running surfaces for the rollers rolling on it 28 while the respective inner edges 42 not used as running or supporting surfaces or edges.

By the arrangement of the rollers 28 on the lifting carriage 22 with respect to the adjacent vertical edges 42 every guide rail 32 are their axes of rotation 30 exactly at right angles 50 oriented to one another, it being noted, however, that the top view of 5 in which this angle 50 indicated, not the vertical distance between the height levels 44 and 46 in which the respective axes 30 lie, recognize. This top view of the vertical guide 14 of the lifting carriage 22 allows particularly well the backlash-free and for high vertical and transverse loads of all conceivable directions suitable suspension of the lifting 22 detect. Because two roles 28 for the upper guide and two other rollers 28 When used for the lower guide, it makes sense to place the two at a common first height level 44 and horizontally spaced lower rollers 28 in relation to the lifting carriage 22 front on the edges 42 the two parallel in vertical alignment guide rails 32 support, and when the two at the common second height level 46 , above the first height level 44 with the lower rollers 28 is arranged, and horizontally spaced upper rollers 28 in relation to the lifting carriage 22 on the back of the two guide rails 32 support. Through these back and front guides of the respective pairs of rollers is an optimal load support of the load bearing with high loads lift 22 guaranteed. At the same time, the roles take care 28 in connection with the guide rails 32 for a wear-resistant and load-bearing rolling bearing 18 of the vertically adjustable lifting carriage 22 ,

Optionally, the roles can 28 have a lubrication to increase the long-term stability and reduce the wear of Wälzpaarungen. Preferably, at least the upper rollers 28 a permanent or loss lubrication 54 associated with a friction-reducing lubricant, so that the lower rollers 28 can be supplied by distributed lubricant. Such lubrication of Wälzpaarungen is useful in many materials used, especially in the preferably used steel pairings of roles 28 and the guide rails 32 , Such loss lubrication 54 the upper rollers 28 is in the 1 to 3 indicated schematically. This is located above the rollers 28 a small lubricant reservoir that by regular lubricant delivery, eg. By a drop oiler, one on the roll 28 resting sponge o. The like., For the desired lubrication of the role 28 can provide. The vertical movements 24 of the lifting carriage 22 with the associated rotation of the rollers 28 around their respective axes of rotation 30 then provide the desired distribution of lubricant over the roller tread 34 on the roles 28 bearing edges 42 the guide rails 32 , In the embodiment shown, only the two upper rollers 28 with such loss lubrication 54 equipped, while it can be assumed that the lower rollers 28 as well as the edges carrying them 42 the guide rails by the continuous vertical movements 24 of the lifting carriage 22 and the resulting distribution of the lubricant over the entire length of the guide rails 32 be taken care of. Possibly. and if necessary, the two lower rollers 28 each with separate loss lubrication 54 and associated lubricant reservoirs.

Another optional equipment element is a safety device 56 through which the vertical movement 24 of the lifting carriage 22 together with the handling element anchored thereto and projecting forward 26 can be blocked if necessary. This safety device 56 is in the representation of 2 recognizable. It comprises one side of the lifting column 12 anchored perforated rail 58 with regularly spaced recesses 60 , in which a motorally movable in the horizontal direction bolt 62 can retract, whose drive on a side boom plate 64 or retaining plate of the lifting carriage 22 is fixed. When the bolt is activated 62 that is in one of the recesses 60 engages, is a load-related vertical lowering of the lifting 22 and the handling element 26 and any load thereon. Such an undesirable lowering could, for example, in case of failure of the motorized vertical drive for the lifting 22 or, for example. In case of failure of a train producing belt or a chain done, but what by the securing device 56 can be reliably prevented. The perforated rail 58 with the recesses 60 is also in the presentation of 6 recognizable.

Especially the 3 . 5 and 6 also let one on the lifting 22 in the horizontal direction and transverse to the lifting and lowering direction 24 of the lifting carriage 22 in the direction of the arrow 66 movable crossbeam 68 recognize that on the lifting carriage 22 via another roller guide 70 , The movements in the horizontal direction transverse to the vertical longitudinal direction of the column axis of the lifting column 12 allowed. The roller guide 70 includes at least one horizontal cross rail 72 at the upper edge of the lifting carriage 22 , on the at least two roles 74 the role leadership 70 the crossbeam 68 are guided. These roles 74 can reasonably be designed and dimensioned as well as the roles 28 the vertical guide 14 , ie with a V-shaped notch of the tread etc. (cf. 5 ). The arrangement of the crossbeam 68 , her flexibility 66 in the horizontal direction and the wide projection of the handling device 26 makes plausible the special loads and the possibly strongly changing load directions, which on the vertical guidance 14 on the lifting column 12 can work, so the special advantages of this vertical guide 14 according to the embodiment shown with the four rollers 28 the rolling bearing 20 and the roles 28 supporting and leading rails 32 could be clarified.

Only in 6 are lower support rollers 76 the role leadership 70 the crossbeam 68 recognizable, on a lifting carriage 22 arranged horizontally oriented guide rail with vertical tread 78 roll off. The two lower support rollers 76 thus have vertically aligned axes of rotation. Depending on the width of the crossbeam 68 It may be useful to have several such support rollers 76 or pairs of support rollers 76 provide, which are preferably arranged at a sufficient horizontal distance from each other. Like the 3 . 5 and 6 clarify, the upper rollers need 74 the role leadership 70 the crossbeam 68 hold and guide in multiple load directions while the lower support rollers 76 only on the treads 78 support, since the load direction does not change here.

In addition to the variant of the profiling of the rollers explained in detail above 28 with their V-shaped notched outer treads 34 an alternative variant can also be a kinematic reversal of the contours of the rollers 28 and the rails 32 or provide their profiles. Thus, for example, according to an alternative, but not shown embodiment variant of the lifting device 10 or the lifting column 12 the roles 28 which the rolling elements 20 form, respectively outer treads 34 having a roof-shaped profiled cross-section. These roof-shaped or triangular formations in the outer treads 34 the roles 28 can be formed in particular by 90 ° elevations or 90 ° peaks in cross section, which an approximately positive rolling of the rollers 28 on the correspondingly contoured guide rails 32 allow. So every role 28 with its V-shaped cross-section preferably on a correspondingly shaped groove or vertically extending notch of the guide rails 32 roll off. As well as the guide rails 32 preferably have indentations or longitudinal grooves with a triangular 90 ° cross-section, there can be the correspondingly shaped roles 28 each be recorded and roll it out exactly guided, creating not only a longitudinal guide for the roles 28 but equally a lateral guidance is given which the roles 28 forces into an exact vertical path and which is able to absorb relatively high lateral forces, for example, by an uneven or changing load on the lifting 22 or in particular by a transversely displaceable and possibly projecting cross-beam 68 on the lifting carriage 22 can occur. Thus, uneven lateral forces through the role design, the contouring of the guide rails 32 is adapted, even in this alternative embodiment of the rolling bearing 18 be recorded in an ideal way. In addition, mixed variants are possible in which, for example, the upper (or lower) roles 28 have the above-mentioned V-shaped notches, while the lower rollers 28 (or the upper rollers) may have the triangular or roof-shaped notches described in the alternative embodiment variant, wherein the upper and lower rollers 28 each on different areas of their associated guide rails 32 have to roll off, these different areas each with the roles 28 have corresponding mating surfaces or mating contours.

It should be noted that the present invention has been described above by way of example with reference to a palletizer. However, this is not meant to be limiting in any way that the invention can only refer to a palletizer. The invention is equally applicable to any apparatus which has the same or approximately the same basic construction as a previously described palletizer. Thus, the invention is also transferable to a liner insert o. The like. Handling device, which may have the same basic structures or components.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.
