The invention relates to a press line for the production of chipboard, in the circuit moving shims are covered with the chip cake, for storage in a press loading device migrate and are fed to the press via this, then via a press emptying device get back into the conveyor circuit, 'to after separation from the finished pressed chipboard and cooling again with a new chip cake to be occupied.

In press lines for pre-pressing plate-shaped Goods on production sheets run sheets, more or less automatically in a cycle, whereby the individual processing stations are passed through. So z. B. the sheets are covered with the chip cake, then migrate to a press feeder to the Speicherang and after filling the press loading device, which is about corresponds in time to the completion of a pressing, pushed the press by an insert arm hi, zo from which the shims with the finished chipboard are pulled out at the same time. the In turn, sheets in the press emptying device move if the chipboard is not made by hand are removed, in a separation station arranged afterwards, then pass through a cooling device empty or are placed in trolleys, where they remain for cooling, and then to the starting point return to the cycle. In automatic press lines, the sheets are after the separation of the compacts on a conveyor track located next to the press line in the opposite direction Direction returned again, are at the end of this conveyor track by lateral conveyance again placed on the conveyor belt, in order to then start the cycle all over again.

These known press lines have the disadvantage of a relatively large space requirement, the practically about twice the area of the normal requirement for the train from the station to the Separating station, with sufficient space to be provided between the rear and return conveyor tracks to carry out repairs or monitoring corridors to execute.

It is an object of the invention to reduce the required space to about half and Simultaneously to simplify the separation process and the necessary device significantly, so that in addition to the space saving, which is particularly important when installing in existing buildings, too a significant cost reduction in the creation of a press line for the production of chipboard

such press lines is possible. In addition, the monitorability of the press line should also be compared to be simplified to previously common press lines.

These goals are achieved when according to the invention the cooling device is located below the press or between its frame stands and if in the same room immediately above the cooling direction in a third level of action one Device for separating the chipboard from those still in the emptying device hot shims is arranged. In this arrangement, the return path can be both advantageous lie in the level of the occupancy path, as well as in other cases are passed under it, in order to be transported to the same level at the end by a lifting device.

In the first case there is a cycle of the sheets in the area between loading, press, emptying, Cooling and recovery up to the loading area, while the sheet metal is under the loading device performs a humming-and-fro movement. In the second case the result is a continuous one Circuit, in the loading device, press, emptying device, cooling station, return line, Lifting device and loading station are included.

The loading and unloading devices are expediently designed in the new press line so that that their individual floors lie close together in the lowered position, while they are in the raised position State at a distance of one level of the press. The one among these Devices guided through the return path can provide enough support in the area around the metal sheets To give the devices, it is best to have three courses.
