The invention relates generically to a plant for production of chipboard and the like made of wood-based material pressed material mats with scattering station, multi-level plate press, loading frame, emptying frame and device for the circulation of screen supports, wherein the screen supports with the pressed material mats in the multi-level plate press insertable and the finished-pressed chipboard or the like. In the working direction of the system behind the emptying rack from the sieve pads can be removed with the aid of a separating device, the device for the circulation guide also being a sieve support return device which leads to a sieve support insertion device and wherein furthermore the device for circulating the sieve supports transport chains having. - In the context of the invention, the words in front of and behind relate to the direction of work or direction of movement of the device for the circulation of the sieve supports. In such a system, the screen support introduction device can be installed in front of the spreading station be arranged. However, it can also be arranged behind the spreading station if special spreading belts and, if necessary, accelerating belts are used, which the wood-based material pressed mats onto the sieve pads to hand over.

In known generic systems (DE-OS 16 53 319, DE-OS 30 07 731) the sieve support return device is as it were in a basement, the one under the multi-daylight platen press with loading frame and emptying frame as well as the downstream and upstream Aggregates is arranged. In addition, a sieve support memory is required, which stores the individual sieve supports and from which the Screening pads in accordance with the overall operating speed of the system, taking into account the number of floors of the multi-daylight plate press are removable.

In addition, one knows (in practice) systems for the production of chipboard and the like Sieve pads but rather work with pressure plates, the pressure plates also circulating. The press plates are on Longitudinal conveyors and cross conveyors with transfer devices for the transfer from the cross conveyors to the longitudinal conveyors and vice versa, promoted. These known measures have so far contributed nothing to the further development of the generic systems, especially since sieve pads not easily promoted with such conveying devices and transfer devices, in particular because of the transverse conveying can be.

The invention is based on the object of a generic system to train further that a basement of the multi-level plate press with loading frame and emptying frame as well as the upstream and downstream units are no longer required and a sieve support memory can be dispensed with.

To solve this problem, the invention teaches that the device for the circulation of the sieve supports behind the separating device has a sieve support stacking device with which several sieve supports are stackable to form a screen support package, that between the return device and the screen support insertion device a screen support unstacking device is arranged and that the sieve pads from the sieve pad unstacking device individually into the sieve pad insertion device are insertable. According to a preferred embodiment of the invention, the sieve support stacking device is for receiving of all screen supports of a loading of the multi-daylight plate press set up.

The advantages achieved are to be seen in the fact that in an inventive System a sieve support stacking device is no longer required. It is true that the sieve pads still have to be stacked, but this is done through the formation of the -: i »colored documents packages, which are not in turn in a sieve documents memory to rest, but to be encouraged. The sieve support packets also have sufficient rigidity to be able to use To be promoted cross conveyors, so that a basement in the sense of the introductory remarks is no longer necessary. A preferred one Embodiment of the invention is characterized in this context that the device for the circulation guide in the area In front of the loading frame and behind the emptying frame, especially in the area of the return device, a slide line for the screen supports as well as having transport chains running along the edge of the sliding road and that, moreover, for the transfer to these conveyor units Cross conveyors are provided. Appropriately, all elements of the circulation guide are in one plane. Of particular advantage is the fact that in the system according to the invention it is possible to work consistently with known units, like these from systems :: belong to the state of the art for a circulation of Siebunlerlagen are set up, these may be known in systems with press plates in circulation. In any case, the details are required so far not the further description. Since "according to the invention, the basement described at the beginning is no longer required, allowed It is the invention to convert systems that work with press plates and circulation guide for the press plates to a system that has a device is provided for the circulation of sieve pads. In such systems, shorter cycle times are generally possible.
