Description

27369 ⁴ 61

The invention relates to a transportable storage device for transporting workpieces between mobile stacking magazines and or between processing machines according to patent no. , (Patent application P 2546 389.2-22).

The main patent has a device for transporting disc-shaped workpieces with a central bore to Object. Here, the workpieces are lined up on a magazine rod and by resilient pawls on the lower End of the magazine rod held, which is part of an overhead conveyor.

It is the object of the present invention, the device according to the main patent on the one hand for wave-shaped To make workpieces usable and on the other hand the capacity for disc-shaped workpieces is essential to increase.

A portable memory according to the main claim is used to solve this problem.

Compared to the main patent, the proposed memory offers the possibility of disc-shaped workpieces with a central bore to also accommodate shaft-shaped workpieces. In addition, the carousel-shaped storage system offers the advantage of that the capacity for disc-shaped workpieces is significantly increased.

6 shows a plan view of a receiving plate for wave-shaped workpieces;

7 shows a plan view of a receiving plate for disc-shaped workpieces.

In Fig. 1, a memory 1 with two receiving platforms 1a is on the magazine rod 2a of an overhead conveyor 2 shown for wave-shaped workpieces W. The memory 1 is by pawls 11 at the lower end of the magazine rod 2a held. These pawls 11 engage in recesses 12 of the Connection flange 1b of the memory 1, as shown in FIGS. 2 and 3 show. In this way, the memory is against twisting secured. The lifting table 6 of the lifting and positioning device 4 is driven by the lifting cylinder 5 by means of pressure medium, the is supplied via one of the pressure medium connections 13, raised. To pivot the lifting table 6, the pressure cylinder 8 operated with pressure medium is provided. In the lifting table 6 fixing pins 7 are attached, which when put on of the lifting table on the connection flange 1b or the receiving platform 1a of the memory 1 secure an exact angular position of the memory. In addition, these fixing pins 7 serve as Driver for the memory 1 when swiveling the lifting table by means of the swivel motor 8. To when swiveling the memory To achieve an angularly accurate position, the lifting and positioning device 4 has an index pin 10, which by a pressure cylinder 9 is pressed into corresponding conical bores 10a (see FIG. 4).

Instead of wave-shaped workpieces W can also be disc-shaped Workpieces S taken from a memory 16 be, which in this case has a plurality of receiving platforms 17, such as. B. Fig. 5 shows. This memory has the advantage over the bar magazine that it can hold disc-shaped workpieces S.

To accommodate different workpieces W or S, the recesses in the receiving platforms 1a or 17 appropriately sized fittings 3 and 18 are used.

The workflow with the portable storage is as follows:

A storage device 1 or 16 filled with workpieces W or S becomes the lifting and positioning device with the overhead conveyor 2 4 transported. There the respective mounting platform 1a or 17 is raised to the desired height, the pawls 11 coming outside the recesses 12 and the fixing pins 7 attached to the lifting table 6 ensure an angularly accurate fixing of the memory. Thereon the workpiece to be processed W or S is removed from a known handling machine and taken from the processing machine supplied or brought back to the memory after processing. The memory is now 1 or 16 swiveled by means of the swivel motor 8 by the angle that

the individual, circularly arranged workpieces W and S occupy each other to the next workpiece by means of the Feed handling machines to the processing machine and from there back to storage 1 or 16.

In this way, all of the workpieces W and S arranged on the receiving platform 1a and 17 are processed are supplied, with the index pin 10 each after the swivel motor 8 is switched off in order to maintain the swivel angle precisely is pressed by the pressure cylinder 9 into a conical bore 10a to the lifting table 6 or the memory in the desired Bring an exact angular position.

If the memory 1 or 16 has several receiving platforms 1a or 17, as shown in FIGS. 1 and 5, the Memory 1 or 16 raised by the lifting cylinder 5 to the respective heights. When all workpieces have been processed, the Storage by means of the overhead conveyor 2 of a next station for further processing or another means of transport are fed.
