DEVICE FOR DELIVERY OF SHIPS RELEASED FROM COMPRESSED CHIPBOARDS

The invention relates to a device for reloading pallets released from pressed particle boards in a synchronous motion, from a conveyor guided through a single-layer press to a forming belt conveyor continuously circulating the pallets. using a conveyor belt.

CH patent publication 380 781 discloses such a device, which, however, is very cost-effective with respect to the movable platforms, since three Puri stusal bases have to be moved in each case from a conveyor which is moved continuously through the press. In addition, this inevitably results in long transport routes, which inevitably leads to downtime.

DE-A-16 53 319 also discloses a device 20 in which, in order to reduce the stroke time, the flexible substrates are conveyed through a hot press and then, after the finished chipboard has been separated from the flexible substrates, the flexible substrates are stored in a warehouse below the press and placed on the conveyor. . Also shown here is a rotary conveyor which conveys the shaped pallets released from the incorrectly applied step webs to the distribution conveyor in priority. Here, too, there are long transport routes that lead to lost time.

Starting from the prior art mentioned above, it is an object of the invention to further develop this known device so that the number of pressing trays conveyed simultaneously from a synchronous conveyor can be reduced and the downtime can be shortened. This object is solved according to the invention by means of the features set out in the claims. By arranging two grippers on each side at a distance equal to half the conveyor path of the synchronously conveyor according to the invention, it is obtained that during each standstill of this conveyor the gripper of the forming conveyor belt 10 released from the coated flexible substrate behind the end strip, which results in a compact structure of the entire conveying device which, in addition to this, does not require any additional auxiliary conveyors and which, when the press is a hot press, does not require any storage below the hot press.

The accompanying drawing illustrates the invention in more detail. In the drawing:

Fig. 1 shows a schematic side view of a synchronously moving conveyor and a forming belt conveyor when handing over a flexible substrate, and Fig. 2 is a top view of the device shown in Fig. 1.

According to Fig. 1, a forming belt conveyor 1a equipped with grippers 2 attached to a chain conveyor 4 to each left and right of the flexible substrate 3 an end strip 8, behind which the grippers 2 of the forming belt conveyor 1 or the grippers 10 of the synchronously moving conveyor 7 can grip. During transport, the speed of the synchronous conveyor 1 is higher than that of the continuously moving forming belt conveyor 1. Accordingly, the grippers 10 of the synchronous moving conveyor 7 reach the grips 2 of the forming belt conveyor 1 at the delivery point 6 and at the same time pull the inside the press 11 shown schematically in the end strip 8. When the chip web 5 to be pressed has stopped, the single-layer press 11 is closed, while the synchronously moving conveyor 7 5 remains standing. Due to the procedure whereby the chip web 5 is pulled on the flexible substrate 3 by means of this end strip 8 inside the single-layer press, the flexible substrate provided with the chipboard is pulled out of the single-layer press. The chipboard pressed behind the pivot wheel 10 of the synchronously moving conveyor 7 is separated from the flexible base 3, while the flexible base 3 with its end strips 8 moves in the direction of the form belt conveyor 1.

If the four strokes of extending the conveying a imellä 7 in this case is two gripper 10 and if the mutual distance 15 is half as large as the pace for the passing of the conveyor 7 of the total transport length, the grippers 10 will exactly after half revolution of the stand, and during the pause that occurs in the compression stroke because, fas the conveyor belt conveyor 1 may grip the end strip of the flexible substrate 3 released from the rear by the return run of the forming belt conveyor 1 and transport the substrate back to the forming station 1e not shown for re-loading with chip material by the blowing or throwing rotation method.

Figure 2 shows a top view of the delivery between the forming belt conveyor 25 and the synchronously moving conveyor 7.

First, the grippers 2 of the forming belt conveyor 1 lead the end strip 8 to the delivery point 6. A pair of grippers of the synchronously moving conveyor 7 are brought to this position through the pivot point 14 at a higher speed against the end strip 8. The end strip 8, with a flexible base 3 not shown, which is loaded 1 in the step web 11a 5, is now pulled inside the single-layer press 11 shown in broken lines, while the grips 2 of the forming belt conveyor 1 exit through the second turning point 15 and are brought back Ic. Before this, however, these take over the flexible substrate 3 released from the chipboard, after the grippers 10 of the synchronously moving conveyor 7 have carried it around the swivel wheel 12, and transport it back to the forming station.
