Description

GERMAN

In the previous, automatic foundry assembly line systems the production of the molds, the weighting and pouring, and also the knocking out and the return transport of the empty boxes takes place to the molding machines automatically. This ensures that the number of people required to operate one such plant required labor is significantly reduced.

So far, however, the replacement of the model plates has not been taken into account in such systems. It is So still necessary to this day, for this, not least made more difficult by the weight of the model plates and therefore a particularly time-consuming additional work step, not at all for the other work to keep the required manpower available especially when there is only a small amount due to manufacturing Frequent plate changes are required due to the number of pieces. The well-known automatic systems therefore only work economically when producing large quantities, because here the replacement the loss of work due to the model plates is within acceptable limits.

The invention overcomes this deficiency by means of a device for exchanging model plates within automatically operating foundry assembly line systems, which with the help of a program control the Replacing the plates automatically regardless of the number of pieces to be produced.

To solve this problem, a device is proposed in which the new is that between a program-controlled model plate store and an automatic molding machine one of a zero position by program control both in the direction of the model plate store and of the molding machine automatically movable carriage with mounting devices that can be swiveled by 180 ° by means of a rotary drive for two or more model plates is provided, which the plates from the molding machine or removes the model plate store or places it on these devices. After another Proposal, the model plate store can advantageously be designed as a paternoster.

The arrangement of a paternoster is already known in double-shaft drying ovens, and it is Also no longer new to use automatically movable trolleys for moving goods. It is it is still common to use such wagons even in connection with a paternoster, but all have these facilities have nothing in common with the invention, since their subject matter, namely the creation a program-controlled model plate store in connection with a program-controlled relocating device between the molding machine and the plate store, cannot be taken.

Gerhard Wendt, Hemmingen-Westerfeld near Hanover, has been named as the inventor

The invention is explained in more detail using the schematic drawing.

Between a trained as a paternoster, pro

ag gram-controlled model plate storage 1 and one automatic molding machine 2, a carriage 3 is arranged, which by a rotary drive 4 by 180 ° pivotable, by means of devices 5 and 5 'can be raised and lowered receiving devices 6 and 6' for has the model plates 7 and also by program control from a shown zero position can be moved automatically in the direction of the pattern plate paternoster 1 or the molding machine 2, as well is controllable with regard to the stroke iind rotary movements.

This device works as follows: In the zero position, the still empty carriage 3 is located between the paternoster 1, which carries the model plates 7 on swings, and the molding machine 2. The model plate paternoster 1 is, controlled by the preselected program, in the position that the inclusion of the preselected model plate by the receiving device 6 of the carriage 3, z. B. from the swing D of the paternoster 1 allows.

The carriage 3 then leads to the right into the model plate paternoster 1, picks up the model plate 7 by means of the receiving device 6, lifts it off the swing D with the aid of the device 5 and moves the model plate 7 back to the zero position, whereupon the paternoster 1 is moved back into the position that is required to deposit the model plate 7 currently on the molding machine 2.

S »527/406

In the exemplary embodiment, the paternoster 1 moves until its swing L assumes the previous position of swing D.

Is the number of pieces previously dialed into the program control by the automatic molding machine 2 finished, the finished molding box is moved out of the machine, a new empty box by the empty box swivel table 8 but not yet retracted. So it is * both the Forming machine 2 and the way for the carriage 3 free, SO 'that this as soon as the automatic control of the overall system the termination of the just mentioned. Indicates operations, from the zero position to moved to the left of the molding machine 2 and according to the type already described by means of the Devices 6 'and 5' can accommodate the model plate 7 located in the molding machine 2. Afterward the carriage 3 moves back to the zero position, where the lifting and receiving devices 5, 6 and 5 ', 6' can be pivoted through 180 ° in order to then immediately back to the left of the molding machine 2 approach and the plate 7 previously removed from the model plate paternoster 1 by means of the devices 6 and 5 to be placed on the molding machine table. The carriage 3 then moves back into the Reset to zero.

The automatic molding machine 2 is now put into operation again after a new empty crate has been brought in by the empty crate swivel table 8. While the molding machine 2 is already working again, the model plate 7 previously exchanged from the machine 2 can be placed in the associated swing L by moving the carriage 3 up to the model plate paternoster 1 with the aid of the devices 6 'and 5'. The carriage 3 then moves back to the zero position, and the model plate paternoster 1 is moved into the new position which enables a new model plate preselected by the program to be picked up. The working cycle described above then begins anew.
