The installation comprises a bunker 1 which is supplied with aggregates by some kind of feeding device such as a conveyor belt, a conveyor, an endless chain, etc. This bunker releases the material, which consists for example of concrete, to a slide 2 which has the shape of a box, the capacity of which is at least equal to that of the mold or molds it is intended to supply. The device has two pouring stations and k , which are arranged on both sides of the bunker 1, the bottom part of ^{which is provided with a metering device l r} in order to deliver the required amount of material to the box 2.

Each casting station has a casting mold 5 in a known manner which rests with its lower part on a plate 6. It also has a compressor 7 which is arranged to be movable in a vertical plane. The dimensions of the plate 8 of this compressor are necessarily smaller than that of the mold 5, so that the plate 8 into the interior the box of the casting mold can penetrate in order to compact the concrete that passes through the slide valve 2 in this Casting mold will be introduced.

In addition, the support 11 of the plate 6 forming the bottom of the casting mold, the mold or casting table, has a vibrating device 12, which sets the whole thing in vibration and complements the solidifying effect of the compressor 7 .

The device also has a feed device in a known manner for the plates ό, which consists of two plate magazines 9 and 10, in which the plates are stacked and each of which has a drive device Inform of a piston drive 91 or 101, which, during operation, grips the lowermost plate 61 of the stack of plates contained in each plate magazine and places them under brings the mold 5 so as to form the bottom of the mold.

The two casting stations 3 and k are arranged symmetrically on both sides of the bunker 1. From its filling position, in which it stands below the bunker 1, the distributor slide 2 experiences an alternating translation movement up to the distributor position, in which it releases the material contained in it into any of the molds of the two casting stations 3 and h . During its translation movement, the distributor slide 2 is controlled by a double-acting piston drive or by a mechanical rack and pinion control, the two directions of which are used in order to avoid dead times in this way.

According to the invention, the supply of disks ό takes place from the disk magazines 9 and 10, which are symmetrical with respect to the transverse axis Y-Y 'of the machine, as can be seen from Figs. In this way, the supply takes place parallel to the longitudinal axis X-X ', thanks to the piston drives 91 and or other means which are arranged at the magazines 9 and 10, respectively.

After removal from the mold, the cast products are placed on the plates by a central conveyor 13 transported away, which is aligned with the axis Y - Y «L. An ejector 15 in the form of a piston

drive, which is arranged at each casting station 3 or 4 moves the platen and molded products from position 62, for example to position 63 · In a modified embodiment the movement from position 62 to position 63 can be accomplished by another plate 6l, which is pushed under the casting mold by the piston drive 101. The transport device then takes care of it 13 for the removal of the cast products on the plates to the subsequent work station. The plate in position 63 can be moved in various ways, for example by means of a piston drive or a roller table.

The material fed to the bunker 1 is metered by the metering device 1 ', which is provided at the lower end of the bunker, and discharged into the distributor slide 2, which is arranged opposite the bottom of this bunker. As soon as the distributor slide 2 is filled, it is set in motion by the drive device 14, for example in the direction of the casting station 3. As soon as the distributor slide arrives at this casting station, the material it contains is introduced into the casting mold 5 by means of a vibrating device as is commonly used. The distributor slide 2 is then returned to its starting position, the filling position, and again receives a metered amount of material. During this, the compactor 7 is brought into its compacting position, controlled by a drive device, in order to compact the concrete previously introduced into the casting mold 5 of the casting station 3. During this time the concrete-filled manifold slide 2 is moved to the pouring station h in order to dispense its contents into the casting mold 5 of this pouring station, whereupon the box is again fetched to its place under

Au 9881/0732

to take the bunker 1 again *. During this time has the plate feeder alternately supplies the casting stations 3 and 4 with plates thanks to the drive devices 91 and 101, the cast plates coming from the plate magazines 9 and 10 one after the other Allocate casting stations, where they work in antiphase.

As soon as a component that has been compacted by the compressor 7 and vibrated by the vibrating device 12 provided in the mold or casting table 11 and is thus finished, the compressor 7 and the casting mold 5 are started up so that the component after molding on the Base plate 6 rests.

From Fig. 3 a conveyor system can be seen, which is intended to transport the products from the first work station, the casting station, to a second station, which is a drying or setting oven, and finally to a third station, in which the various products or precast concrete blocks are sorted.

This conveyor system 4 fits into a production line which has a manufacturing or casting station 1 _r, a drying station 2 and a sorting and storage station for the finished blocks.

The products leaving the casting station 1 are arranged on flat plates as described above. They are brought to the conveyor system with the help of a 4ll belt conveyor. The plates that follow one another on this conveyor carry various products made by the casting plant 1, which in turn may have one or more casting stations with different mold patterns

can be provided. Whatever the case, they will One after the other on the plates one after the other. In contrast, it is for reasons of economy advantageous to treat the products in the binding chamber 2 in stack form. Any stack of plates is introduced into the interior of the chamber behind the previous one. This way, the exit der.Pertigungsstation 1 existing sequence of the different Keep products inside the successive stacks in the same compartment.

The conveying cycle effected by the conveyor system 4 has two sections: The first section consists of to capture the products leaving the manufacturing station 1 and transfer them to one of the drying or setting chambers to bring workstation 2. The second Section consists in capturing the finished products in another chamber of the drying station 2 and they to the third work station, the sorting and Storage station to bring.

For the implementation of the first section of the Conveyor cycle required parts include a 'connecting conveyor, which extends from the manufacturing station 1 to a plate elevator 4l, one with several forks provided carriage 43 'which grasps the stacks of panels on the elevator 41 and moves them along a railroad or Track 431 transferred to a transfer platform 44, which runs on a track 44l, which ie right angle is aligned with track 431. This transfer table 44 ensures the lateral offset from the axis of the elevator 4l to the axis of one of the chambers, for example the chamber 21, the workstation 2 out.

The system parts that execute the second section of the conveying cycle include the tracks for the circulation of the

409881/0792

Carriage and the transfer table as well as a plate elevator 42 stacking the plates.

The conveyor system works as follows: The plates that leave the work station 1 and carry the same parts or different parts in a predetermined order are brought to the elevator 4l by means of the endless conveyor 4ll. The elevator 4l causes the plates to be stacked, for example η plates on top of one another. The multiple fork carriage 43, which has at least η forks one above the other, grips the slabs inside the elevator, moving on the track 431 ^ When the plates have been picked up by the multiple fork carriage, it moves backwards and moves onto the sliding platform 44, which opens up track 44l runs y which is lower than track 431 at point A. The transfer table then moves sideways and brings the carriage 43 into alignment with the chamber that is currently being filled, for example that of the drying or setting chamber 21. The The carriage 43 leaves the transfer table 44 and moves on on a track 4.33. Inside the chamber 21, it places the entirety of the n 'plates on lugs, one on top of the other, which are provided for this purpose the transfer table 44 back in position B. The loading cycle or the first section of the conveying cycle is thus ended e then moves to one of the other chambers, for example to chamber 23, it being assumed that chamber 23 is a chamber in which the drying or setting of the products has ended. The transfer table therefore moves into position C, in which it is aligned with the longitudinal axis of the chamber 23. The carriage 43 drives on a track 435 into the chamber 23 and detects one

4Ü9881 / 07 9 2

Stack of η-plates and then returns to the transfer table 44 back, which moves up to position D and stands still there, in which it is with the axis of the elevator 42 aligns. The ¥ agen 43 moves forward as a carrier of the plates on a track 432 and sets its Stacks of η plates carrying the dry products are removed in elevator 42. This one stacking the plates Elevator 42 then places each plate one after the other on a transport roller table 421. The panels are then transferred to the third workstation 3. This station 3 has a device 31, which on the one hand serves to recondition the plates and, on the other hand, the plates with the aid of a conveyor 311 returns to the first work station, during which the finished products are carried by a second conveyor conveyed to a further device 32 within the station 3 that sorts the various blocks to deliver them to the warehouse.

From Fig. 4, a part of the device can be seen in a perspective view, namely the manufacturing station 1, the connecting conveyor 4ll between the manufacturing station 1 and the conveyor system 4, the elevator 4l, the elevator 42, the car 43 and the tracks 431,432 and 441.

The panels brought in by the conveyor 44l are successively placed on eight superposed levels E 1 to E 8 raised. In FIG. 4 it can be seen, moreover, that the lifting of the plates has not yet ended is, insofar as the stack inside the elevator 4l only contains the plates E 3 to E 8, while the plates E and E 2 are still on the way on the endless conveyor 4ll. The vague 43 'on the one with the axis of the elevator 41 line 431 is running, approaches this elevator,

4U9881 / 0792

around the plate stack E 1 to E 8 by means of its forks F 1 up to F 8.

In the same Fig. 42 of the elevator is being loaded with a stack of plates E ¹ I to E'8 carrying the dried products. This elevator distributes just these plates to the continuous conveyor, which is arranged in the background, but cannot be seen in the figure.

In Fig. 5, the multiple fork carriage 43 can be seen, the carries a stack of plates E 1 to E 8. The carriage 43 leaves just the track 431 and drives on the transfer platform 44, which runs on track 44l, which is aligned at right angles to track 431. In this figure you can see that the transfer table 44 with space to the track 431 has a piece of track on which the carriage 43 Takes place to perform a sliding movement from one workstation to another.

In Fig. 6, a stack of plates can be seen in the interior a drying or setting chamber. In this figure, the plates E 1 to E 6 are in a chamber that is being loaded, which is why they are carrying fresh produce. The panels are on the side Detached cleats T 1 to T 6, which are firmly connected to the masonry of the drying chamber. The tram 43 runs on track 433, which is in the longitudinal axis of the chamber is relocated.
