Description

The invention relates to a placement device for coil creels, with at least one assembly device, the full bobbins of a spool supply on horizontal Transport mandrels are taken over by an endless conveyor are vertically adjustable all around, and with a coil carriage, the between the placement device and the The creel is movable and the horizontal carriage arbor has that with the creel of the creel in one Transfer position of the bobbin wagon and from one Spine carriers are held with a limited vertical Adjustability is provided.

A placement device with the aforementioned features is known from EP-A-0 467 101. If the placement device the transport mandrels are operated by the endless conveyor, with which they are securely connected in order to lower idler wheel of this endless conveyor moves around. Because it there are very large coil lengths, the transport mandrels must accordingly To be long. On the other hand, the transport mandrels have no ground contact when rotating the lower deflection wheel. That cannot be ruled out if the lowest position a transport mandrel of the endless conveyor comparatively close to the ground must be arranged because the coil mandrel to be fitted of the creel is arranged near the ground. It is now conceivable for the assembly device in detail Form so that the bottom has a slot for the mandrel pass has that folding mandrels are used, which at Circulation around the deflection wheel can be created, or the placement device to raise if necessary. All of the above Possibilities are obviously technically complex and unsatisfactory. The placement device seems to make the most sense to equip so that even their longest transport mandrel the floor when rotating around the lower deflection wheel can't touch. In this case, however, it is necessary any height differences between the lowest position a transport mandrel of the placement device and to compensate for the lowest position of a spool of the creel.

From the aforementioned EP-A-0 467 101 is a coil carriage known to take slip patterns on the creel is provided with a mandrel support that is vertical can be adjusted. The mandrel carrier is an endless one Chain pair designed with mandrel holding plates. With a special control can be achieved that every horizontal Car mandrel in alignment with a coil mandrel of the creel can be arranged. It is assumed that each horizontal mandrel runs around a lower idler wheel can without hitting the ground. This coil carriage is re its mechanical training and control of the drive positioning the horizontal carriage arbors obviously expensive.

From DE-A-42 13 049 is a device with the input known features known. The limited vertical Adjustability is matched to the fact that gate mandrels are adjacent Gate frame by half a mandrel pitch in height are offset from one another. As a result, it is not possible a coil on a gate mandrel other than the predetermined to hand over. As a result, the applicability of the device for different sampling of coil gates limited by the coil carriage.

From DE-A-35 38 838 is an assembly device known with a placement device that a coil carriage supplied with full bobbins of a bobbin supply, whereby the bobbin wagon is provided with an endless conveyor which moves around half a feed step can be moved to intermediate positions to reach, on which there are crevices, that to a horizontally adjacent gate mandrel by half vertical pitch length are offset in height. As a result of Endless conveyor of the bobbin wagon is its construction very complex.

The invention is therefore based on the object of an assembly device with the characteristics mentioned above to improve the height difference between a lowest Transport mandrel and a lowermost coil mandrel with the help of a simple bobbin carriage and beyond the assembly of the creel is carried out more flexibly can be.

This object is achieved in that the vertical Adjustability of the mandrel carrier is practically the same as the vertical one Distance between two mandrels is that the mandrel carrier in a supporting frame of the bobbin carriage vertically sliding back and forth is guided, and that a piston-cylinder drive is present, the one hand on the support frame of the bobbin and on the other hand is supported on the mandrel carrier.

It is important for the invention that the vertically limited adjustment of the mandrel carrier is sufficient to with such a trained coil carriage different Floor clearances of a transport mandrel of the placement device and to be able to compensate for a spool of the creel, while achieving a structurally simple training becomes. The constructively simple design of the bobbin wagon is due to the fact that only a comparatively small Vertical adjustment is required, which is expensive Drive and a correspondingly complex drive control do not need. Ultimately, it is for solving the technical problem of concern, the limited vertical To make mobility in the area of the bobbin carriage instead in the area of the placement device, which is a comparatively has complicated structure and where lifting in the area this placement device when using a bobbin wagon, where the ground clearance of the wagon arbor to the ground clearance the coil mandrel of the creel is adapted, should happen every time a mandrel rotates below.

The assembly device so that the mandrel carrier practically the vertical distance between two mandrels is vertically adjustable, means one slightly larger adjustment path of the mandrel carrier than only for the Height compensation between the transport mandrel closest to the ground Assembly device and the coil mandrel closest to the ground Coil gate. However, this is achieved in that the assembly of the creel can be performed more flexibly.

The placement device is designed so that the Mandrel carrier in a support frame of the bobbin carriage vertically is guided back and forth. All parts of the mandrel carrier are consequently only in two, opposite to each other Directions are moving and accordingly simple can be the structural design. Such shift guides are durable and require little maintenance.

There is a piston-cylinder drive available on the one hand on the support frame of the bobbin carriage and on the other hand supported on the mandrel carrier, usual stroke paths of the mandrel carrier be mastered. Such piston-cylinder drives are robust and not very expensive, even if they are larger Have to move loads.

It is particularly advantageous for the placement device to be designed so that the mandrel carrier has vertical rails, which is vertically displaceable between rollers of the supporting frame are led. With these proven constructive means the formation of the mandrel carrier advantageous to the essentially vertical extension of the coil carriage frame adapted.

It is advantageous to design the placement device in such a way that that the vertically limited adjustability during the travel of the bobbin wagon from the loading device to the transfer position in front of the creel or back automatically is feasible. As a result, the workflow not delayed by movements of the mandrel carrier.

The assembly device is designed that the winder mandrels of the coil wagon row and row on a linkage formed as a parallel to the creel Mandrel carriers are attached. Such a mandrel carrier allows to use a larger number of wagons, so that only comparatively few trips of the bobbin wagon between the creel and the loading device Need to become. The boom is horizontal or vertical arranged. In particular, the mandrel carrier can be designed in this way that he is one side of a rotating frame of the creel can fully populate. That simplifies the Clarity of the processes during the operation of the creel and its refitting.

The assembly device is particularly advantageous further developed in that the supporting frame of the Coil carriage is designed as a bogie that with a Chassis is movable. As a result, the support frame and thus the mandrel carrier rotates relative to the chassis become. This means a significant increase in the number of possible uses of the bobbin in cooperation with the positioning of the placement device relative to Creel. In particular, the assembly device positioned on opposite sides of the bobbin become. As a result, it is possible to use the placement device the given spatial conditions of the whole Adapt winding system better accordingly.

A placement device with a coil carriage, the Support frame is designed as a bogie can advantageously be further developed in that the mandrel carrier wagons pointing in opposite directions having. The bobbin wagon can then double the amount Coils are loaded, so that the time required to move of the bobbin wagon between its loading position and the transfer positions in front of the creel reduced accordingly.

It is possible to design the placement device in such a way that that the placement device is a ground-level centering device has different floor locks is to be engaged. As a result, it is possible that universal usability of the placement device optimal to use by simply switching between different Working positions can be moved. At rail-bound process, for example, between two gate sides are moved, e.g. alternately the To be able to equip coil carriages on both sides of the gate. At suitable equipment with steerable and lockable castors it is possible to use them advantageously between freely selectable Use locations, e.g. between locations on different coil gates. It is then necessary the assembly device with couplings for the energy supply equip.

A further development of the invention consists in the placement device to train so that the placement device on the warping machine side of the creel and on the the side facing away from the bobbin with a bogie provided coil carriage is arranged. As a result of the warmer side Arrangement of the placement device is possible that the workplace of this placement device and the warping machine are adjacent to each other. Consequently can be used with the assembly device if there is no need to work on the warping machine. The work on the warping machine is increasingly reduced, however, because the Number of thread breaks always decreases. It follows from this a significant improvement in production with the overall system in that the same person both warps and equips can.

The coil gate 10 shown in FIGS. 2, 3 consists a plurality of rotating frames 17, each about an axis of rotation 26 can be rotated. Each rotating frame 17 carries on both Sides of several mandrels arranged horizontally in a row 19, cf. Fig.2 and several vertically arranged in a row Gate arbors 19, cf. Fig. 3. There are several rotating frames each assigned to a gate side 27 or 28 and have one Distance from each other caused by the thread take-off is, if the threads of several are pointing towards each other Gate mandrels 19 of the gate sides 27, 28 attached coils 12 between the gate sides of a winding machine be, for example from a warping machine. The pins 19 pointing away from one another of the two gate sides 27, 28 can be freed from unwound bobbin tubes and with full Spools of thread are loaded. After loading and the Unwinding the threads from the adjacent spools of the two frame sides 27, 28 can rotate the rotating frame 17 and the gate mandrels 19, which are then on the outside, can be re-equipped.

The gate mandrels 19 are equipped by means of coil carriages 15. Each gate side 27, 28 is a coil carriage 15 assigned. Each coil carriage can be moved on a rail 29 and secured against tipping over with a guide rail 30, by a support frame 20 of the bobbin carriage 15 over Guide rollers 31 supported on the guide rail 30. Everyone Coil wagon 15 has a mandrel carrier 18 for wagons 16 for Picking up full spools of thread 12.

Each bobbin wagon 15 is with full bobbins 12 in one Area to be populated by a coil transfer position removed between coil carriage 15 and creel 10 have to be. Accordingly, the coil carriage 15 according to FIG. 2, for example in the rear, opposite the winding machine for the threads Coil gate area 33 arranged. Here is a placement device 11 with which the coil carriage 15 can be loaded with full bobbins 12. The placement device 11 can between the assembly positions the coil carriage 15 behind the gate end in the direction of Double arrow 34 can be moved. In Fig.2 it is the right one Coil carriage 15 adjacent assembly position of the assembly device 11 shown with solid lines, while the one adjacent to the left coil carriage 15 Position of the loading device 11 shown in dashed lines has been. In Figure 1, the representation is reversed, the placement device So 11 became the right coil carriage 15 assigned dashed position accordingly the arrow 34 in the left assembly position in front of the left Move coil carriage 15.

The placement device 11 has a variety of Transport thorns 13 with the full bobbins 12 of one Person 35 can be equipped. The coils 12 are on the the transport mandrels 13 turned away from the bobbin carriage 15, see. also Fig. 5, bottom arrow. After that, the Transport mandrels 13 according to the circular arrow 35 in Fig.1 overhead to the side of the pick-and-place device adjacent to the bobbin carriage 15 11 funded. An endless conveyor is used for this 14, which consists essentially of two deflection wheels 36 and link chains or a carrier belt 37 guided above it, on which the mandrels 13 with suitable stiffeners or brackets are attached. As a result, the full bobbins 12 according to Fig. 1,4 and 5 easily overhead be moved. The endless conveyor 14 is controlled manually or computer controlled. It is designed so that the longest transport mandrel 13 caused by long coils without problems passed vertically under the lower deflection wheel 36 can be made without using the floor or a frame part near the floor of the support frame 20 to come into contact. It is there is sufficient distance x2.

For pushing full spools of thread 12 from the pick and place device 11 on a coil carriage 15 or the wagon arbor 16 can the assembly device 11 with Pushing devices are provided, as in the EP 0 467 101 A1 are described in detail. Significant is that the mandrels 13 when pushing the full spools of thread 12 are aligned with the wagon pins 16 so that push-free pushing is achieved. The lowest wagons 16 must therefore have the distance x1 from the ground, that is the lowest possible ground clearance of a transport mandrel 13 corresponds if this is in a horizontal arrangement in a transfer position, that is in the area of a transfer device or at least in a position in which one full spool 12 as intended by the pick and place device 11 can be passed to the coil carriage 15.

On the other hand, the lowest possible ground clearance is x1 a horizontal transport mandrel 13 because of the long Mandrels 13 required clearance x2 generally higher, than the ground clearance x3 of a lowermost gate mandrel 19, cf. Fig. 3. In order to be able to compensate for this, the coil carriage is 15 provided with a mandrel carrier 18 which delimits vertically is adjustable. 1 shows the mandrel carrier 18 vertically adjusted above and Fig. 3 shows it adjusted vertically downwards. For this purpose, the mandrel carrier 18 with vertical rails 21 provided, the support frame 20 or its longitudinal extent are parallel. The support frame 20 has attached to it Rollers 22 which are arranged in pairs. Between two Roller 22 is one of the rails 21 vertically and against the side Tilted with one degree of freedom. The back and forth The mandrel carrier 18 is produced by a piston-cylinder drive 23 concerned, the below the mandrel carrier 18th is arranged. This drive 23 is supported with its cylinder on the support frame 20 and with its piston rod on the mandrel carrier 18 onwards. The support is articulated to the extent necessary. The weight of the mandrel carrier 18 moves the drive 23 to its rest position when it is not under pressure. This rest position corresponds to the height of the wagon arbor 16 the ground clearance x3 of the lowest gate mandrels 19. Only in the case of assembly, i.e. when the coil carriage 15 is to be populated by the placement device 11 the carriage arbors 16 are raised by the mandrel carrier 18 so that the drive 23 is only to be acted upon. As a result of this Short time of loading the coil carriage is the energy expenditure for the drive 23 low.

From Fig.4.5 it can be seen that the assembly device 11 has an endless conveyor 14, the transport mandrels 13 are arranged in a row. In comparison, they are Wagendorne 16 this version of the coil carriage 15 in series and arranged in rows. The mandrel carrier 18 is accordingly a linkage consisting of several lines arranged one above the other Dornstangen 45, on which the Wagendorne 16 in rows are attached one above the other. Such a mandrel carrier 18 can with appropriate guidance in the support frame 20 from one Piston-cylinder drive 23 are applied. It is but possible to do this even when using a bogie integrate. In Fig.4.5 was a piston-cylinder drive 23 of the mandrel carrier 18 not shown. The design of the bobbin carriage 15 in terms of the number and arrangement of its Wagendorne 16 is on the rotating frame 17 of the creel 10th matched so that a rotating frame 17 completely or in each case one side of a rotating frame from a load of a bobbin wagon 15 can be equipped.

For all coil carriages 15 it applies that they are designed in this way can be that their wagons 16 about the vertical distance 25 of two mandrels 19 are correspondingly adjustable. This adjustability can be used for special assembly tasks be used, e.g. to influence assembly patterns or to fit gates with vertically offset division.

4, a coil carriage 15 with a specially designed Support frame 20 shown. This support frame 20 is designed as a bogie and from a chassis 24 supported. The chassis 24 has a support plate 39, which has a central warehouse 40 in its center, which is located on a Transverse axis 41 rests, at the ends of rollers 42 for supporting the Frame 20 are attached against tilting. On both sides of the Central warehouse 40 becomes the support frame 20 with further support devices 43 provided it in the horizontal hold. The axis of rotation of the support frame is supported by a bearing pin 44 determines who engages in the chassis 24.

The coil carriage 15 of Fig.4.5 has the special feature that Wagendorne 16 on both sides of the mandrel carrier 18th available. They are cursed and opposed to each other Orientation oriented. As a result, the coil carriage 15 can be assembled on both sides, which is why after the assembly one side rotated by 180 ° due to its bogie and can then be re-populated. With such a Coil wagons can therefore be assembled by the placement device 11 two rotating frames 17 each half equipped be without the coil carriage 15 to do so from a Transfer position in the area of the creel to an assembly device 11 and back after assembly should be followed. In addition, the coil carriage offers but also the possibility of variable placement device 11 to use. You could namely in Fig.2 on the other Side of the rail 29 may be arranged. From there equipped wagon mandrels 16 can be turned by turning the support frame 20 are directed towards the spool 19. Such Arrangement is particularly advantageous when the warmer side is populated. A bogie of the bobbin carriage 15 is then absolutely necessary, but not a two-sided arrangement from Wagendornen 16.
