Description

The present invention relates to a coil transfer device according to the preamble of claim 1.

Such a coil transfer device is e.g. Subject of DE 42 14 229 A1 (= Bag 1919).

The object of the present invention is to further develop the coil transfer device mentioned in such a way that greater flexibility with high functional reliability is ensured with an even more simplified construction.

This object is achieved by the invention in the said coil transfer device by means of the features of the characterizing part of claim 1.

The advantage of the invention is that the number of parts which are necessarily movable for pulling or pushing off the coils is kept extremely low, which on the one hand can reduce the technical outlay and on the other hand ensures a high level of functional reliability.

This advantage is achieved in that, according to the invention, a single gripper is provided, which, however, has a dual function.

The fulfillment of the double function is made possible by the fact that the gripper can only be swiveled into the coil front area, if necessary, and that the gripper can otherwise be swiveled out of the coil front area, e.g. to be able to be moved from the push-off position to the open position.

The invention thus provides a push-off and pull-up device which can be moved to any necessary position with respect to the coil transfer device by means of the linear driving device, and which there by a simple pivoting movement into the end face area of the coil for its actual function, pushing or pulling up coils can be activated. As a result, coils can in particular also be pushed off a coil mandrel in a defined sequence.

The development of the invention according to claim 2 can be used both for loading a coil intermediate storage and for unloading, the development according to claim 3 allowing the use of the coil transfer device in a space-saving coil intermediate storage.

The development according to claim 4 offers the advantage that the coil transfer device has two operating sides. For example, you can operate a coil intermediate storage on one of the operating sides or a trolley or doffer on the other operating side, where that The full bobbins are taken over in order to transfer them to the intermediate bobbin immediately after removal from the trolley or doffer.

The development according to claim 5 allows that one and the same coil transfer device pushes or winds up the full coils of several coil mandrels at the same time, so that the coil throughput per unit of time is increased. This is made possible in particular because the spool pushing and pulling device is independent of the spindles and not in the free cross section of the spool sleeves to be moved.

The development according to claim 6 is advantageous since in this case the synchronous pivoting movement of the gripping elements solely by the corresponding geometric arrangement of the gripping elements, e.g. is achieved by a V-shaped, preferably rectangular fork.

The development according to claim 7 offers the advantage of a space-saving use within a creel with a plurality of horizontally and vertically arranged in rows or columns spindles.

The further training according to claim 8 receives special attention. In this case, it is advantageous to arrange the travel axis of the driving device substantially in a normal plane to the connecting line between two spindles and the gripping elements to be diametrically opposite to the travel axis. In a special case, the free end of the driving device is T-shaped.

The invention is explained in more detail below on the basis of exemplary embodiments.

Unless otherwise stated below, the description that now follows always applies to all figures.

In particular, FIG. 1 shows a bobbin reloading device 1 with a bobbin pusher and bobbin winder 2, which can be brought into a push-off position 4 or a winder position 5 by means of a linear driving device 3 and activated there in each case.

The linear driving device is aligned parallel to the longitudinal axis of the coil and is movable along this parallel on an associated driving axis.

The spool pusher and spool puller 2 consists of a single gripper 6, which is used both for pushing off and for pulling up spools 20, the gripper on the driving device 3 in push-off position 4 or pull-up position 5 being pivotable into the spool end region 7 and the gripper on End of the deportation route or winding path can be pivoted out of the coil face region 7.

The swiveling movement 7a takes place as a rotary movement about the driving axis of the linear driving device 3, specifically by rotating the linear driving device 3 together with the gripper 6 located at its free end.

As can be seen, the coil reloading device 1 accommodates a large number of coils 20 of the same type, which each sit on a coil mandrel 13 with a small distance between the mutually facing coil end faces 7.

The push-off position 4 is now the position into which the gripper 6 has to be moved in order to completely engage the coils 20 seated on the spool mandrel 13 as soon as the pushing off of the coils 20 from the spool mandrel 13 is desired or necessary.

In this push-off position 4, the gripper 6 is now pivoted behind the coil face region 7 of the innermost coil 20 in such a way that when the driving device 3 moves in the direction of the free end of the coil mandrel 13, the coils 20 located thereon are completely pushed off.

The spool winding position 5, on the other hand, is the position in which the linear driving device 3 is in the dashed position. In this fully extended position, the gripper 6 is able to reach behind a corresponding package of coils, which is, for example, attached to the mandrel 19 of a doffer or a trolley 21 and to take it over the mandrel 13.

For this purpose, a coil mandrel 13 of the coil transfer device 1 is brought into alignment with a supporting mandrel 19 of the doffing device or the trolley 21. Then the driving device 3 moves the gripper 6 to the intended coil end face region 7. Next, the gripper 6 swivels behind the approached coil end face 7, after which the driving device 3 is then drawn in in the direction of the coil transfer device 1. The gripper 6 engaging behind the coil end face 7 takes the coil package located on the support mandrel 19 with it and pushes it completely from the support mandrel 19 onto the coil mandrel 13 into the position shown.

In the embodiment shown, the coil transfer device 1 is attached to a chassis 8, which can be moved as an operating device along a coil intermediate storage 9. As can be seen, the transfer area from the trolley 21 to the coil transfer device 1 is on one side of the chassis 8, while the intermediate storage 9 is arranged on the other side of the chassis.

In order to be able to transfer the full bobbins 20 received by the trolley 21 to the intermediate storage 9, the bobbin transfer device 1 can be moved in height by means of an elevator 10 and the bobbin transfer device 1 is furthermore mounted on a platform 11 which is about a vertical axis 12 of the Elevator 10 is rotatable.

In the present exemplary embodiment, the platform 11 can be rotated by at least 180 degrees, specifically along the direction of rotation 12a. Preferably, the ends of the possibility of movement of the platform 11 in the direction of rotation 12a are each perpendicular to the travel path of the chassis 8, as a result of which the full bobbins 20 are transferred from the trolley 21 to the bobbin winder 13 or from the bobbin 21 essentially without tilting Spool mandrels 13 on the bearing mandrels 9a of the intermediate storage 9 can take place.

It should be expressly said that the coil transfer device can only be provided with an elevator 10, or in a further development with the elevator 10 and the rotatable one
Platform 11 or in a special embodiment only with the rotatable platform 11.

The elevator 10 serves to position the winding mandrels 13 along the upward movement 10a or downward movement 10b after the take-over of the full bobbins from the trolley 21 in such a way that the winding mandrels 13 lie at one level with the bearing mandrels 9a of the intermediate storage 9 to be loaded.

As soon as the coil mandrel 13 and the bearing mandrel 9a are positioned in alignment, the full coils 20 can now be transferred from the coil mandrels 13 to the bearing mandrels 9a.

In addition, it can be provided to design the platform 11 in two parts, one platform part being rotatably seated on the elevator 10, and the other platform part being displaceably guided in the longitudinal direction of the winding mandrels 13 on the rotatably mounted platform part. This possibility of movement is represented by reference number 22. This measure creates a narrow walkable aisle between the coil intermediate storage 9 and the chassis 8.

It is a special development of the invention that the coil transfer device 1 has several coil mandrels 13 and that the gripper 6 consists of several gripping elements 6.1, 6.2, which can be pivoted synchronously and in the same direction with respect to the spool 13. It is then advisable to provide a uniform horizontal distance, also called division, for the support mandrels 19, for the coil mandrels 13 and for the bearing mandrels 9a, in order to be able to operate trolleys 21 and intermediate storage facilities 9 without delay and immediately without a transfer station.

In the present case, two spools 13 are mounted horizontally next to one another on the spool transfer device 1, with such a distance that a space 16 remains between the attached full spools 20 (cf. FIG. 2).

As shown in FIG. 2, a V-shaped gripper 6 now engages with one of the gripping elements 6.2 in the space 16 between the coil mandrels 13, while the other gripping element 6.1 lies outside the coil mandrels. In this position, the driving device can be moved into the push-off position 4 or the open position without touching a coil end region 7.

As further shown in FIG. 3, the driving device 3 can run essentially between the spool 13 and parallel to it, preferably in a normal plane to the connecting line of the longitudinal axes of the spool 13. In this case, it is proposed to relate the gripping elements (6.1, 6.2). the driving device 3 to be arranged diametrically to each other.

The arrangements are such that both the first gripping element 6.1 and the second gripping element 6.2 are pivoted synchronously during a swiveling movement, for example in the direction 7a, and in the same way immerses behind the respectively assigned coil end face regions 7 of both coil mandrels 13 in order to either pull them open or the deportation to accomplish the full coils 20 on both coil ends 13 or from both coil spindles 13 at the same time.

For this purpose it is recommended according to Fig. 2, to arrange the linear driving device 3 with the spool 13 so that the longitudinal axes of the spool 13 or the direction of movement of the driving device 3 are in the corners of a triangle, or gem. Fig. 3 that the driving device 3 runs in a normal plane to the connecting line of the spool 13, preferably the gripping elements 6.1, 6.2 sit wing-like on the head of the driving device 3 and form the shape of a T with this.

In the present embodiment according to Fig. 2 is due to the symmetrical arrangement of the triangle isosceles triangle, the distances between the driving device 3 and the two spool 13 are identical.

1 that the undercarriage 8 is guided between a single-track lower travel path 17 and an upper travel path 18 lying vertically above it. This increases the positioning accuracy and prevents the chassis from swinging when loading and unloading.

In the present case, the upper route 18 is exactly aligned with the lower route 17. However, this need not necessarily be the case. Furthermore, the upper track 18 is also designed as a single-track track; however, this means that the invention is not restricted to this design. It is essential, however, that the chassis 8 is guided in single track near the ground, since the invention has recognized that the width of the chassis 8 can remain very narrow in this way.

For this reason, the available space for an intermediate storage 9 can be used optimally. Any tilting moments that act on the chassis 8 are easily absorbed by the laterally fixed clamping of the chassis 8 between the lower travel path 17 and the upper travel path 18.
