The invention relates to a plant for the production of chipboard, which from a scattering station, a multi-stage press and a storage unit each with means for simultaneous loading and emptying consists of all levels of the press with or from the chips scattered on the loading plates.

The aim of the invention is to shorten the conveying paths, especially for the loading plates, the space required to keep it as small as possible for such a system and also to keep the workflow clearer than before, ultimately also to simplify the operation.

For this purpose, according to the invention, the spreading station with the associated conveyor passage is above the press arranged, the conveying direction being parallel to the direction of passage of the press.

For conveying the sprinkled loading plates downwards from the spreading station and for conveying them upwards the empty loading plates to the spreading station can otherwise only be used for loading or emptying the Press used lifting baskets are used. Special conveyors can also be provided.

An advantageous embodiment of the system according to the invention is that in front of the press a from the spreading station downwards, behind the press an upward conveyor to the spreading station, at the same time in on known way for loading or emptying the press usable double paternoster unit is arranged, wherein the removal of the Spangutpreßlinge from the feed plates in each case the path between the press and the spreading station from the upwardly conveying double paternoster plant he follows.

The use of double paternoster units as storage for loading and emptying a Multi-tier press with omission of the lifting baskets is known per se.

In the context of the invention, however, the double paternoster mechanisms still have a function, namely they are also the intermediate conveyor between the spreading station and their own storage part, or vice versa.

The path of the loaded and empty loading trays is therefore the shortest imaginable, their number the smallest possible.

It is useful if the conveyor line is between the place where the Spangutpreßlinge is removed is formed by the loading plates and the spreading station as a cooling zone for the loading plates.

Only a few empty feed plates need to be located in this zone, so that the distance of the conveyor aisle of the spreading station from the upper system for the production of chipboard

part of the press is kept quite small, so it can be easily placed on the press. By the weight of the spreading station is even the press supports, which are stressed by tensile forces during pressing relieved.

For the downward conveyance of the chip compacts removed from the loading plates, another may be used Double paternoster unit can be provided, which can also serve as a cooling store.

The workflow in the system according to the invention, which is illustrated in the drawing, when using double paternoster mechanisms the following is:

A feed plate is located on the conveyor aisle of the spreading station 9. This can be under the actual The spreader or these run back and forth over the feed plate.

When the spreading is complete, the feed plate in the double paternoster unit 1, at the same time an empty one The feed plate from the double paternoster unit 5 is pushed onto the conveyor aisle of the spreading station 9 or pulled.

The spreading feed plate moves step by step according to the spreading cycle below. If the storage part of the double paternoster unit 1 is filled, the loading arm 2 comes into operation and pushes all the sprinkled loading plates in the storage part into the open one Press 3.

When the pressing is complete, the emptying arm 4 pulls all of the loading plates with the chips from the reopened press 3 (which is loaded again at the same time from the other side) in the double paternoster unit 5, which gradually promotes the feed plates upwards.

During the pressing time, the spreading station 9 and the double paternoster units 1 and 5 work unchanged Further.

Somewhat above the top floor of the press 3, each chip compact is now

slidable sheet is pushed off or pulled off and arrives via an intermediate conveyor aisle 6, for example in a third double paternoster unit 7, which conveys the Spangutpreßlinge downwards. At the same time they can be cooled there.

The removal of the Spangutpreßlinge from the double paternoster plant 7 is arbitrary, so individually or in a stack.

After the chips have been removed, the now empty feed plates move on upwards, where they expediently pass through a cooling zone 8.

Once at the top, each feed plate is pushed onto the conveyor aisle of the spreading station 9.

Both double paternoster units and, if available, also the third double paternoster unit 7 preferably work synchronously.

The other possibilities, such as the use of lifting baskets instead of or in conjunction with double paternoster units or with other vertical or inclined conveyors inevitably from the new arrangement of the spreading station above the press. So you shouldn't further described.

Claims (4)

Patent claims: 1. Plant for the production of chipboard, which consists of a spreading station, a multi-stage press and each a memory with means for the simultaneous loading and emptying of all floors of the press with or from the chips scattered on loading trays, characterized in that that the spreading station (9) with the associated conveyor aisle is arranged above the press (3), the conveying direction being parallel to the direction of flow of the press. 2. Plant according to claim 1, characterized in that in front of the press (3) one of the Spreading station (9) downwards, behind the press an upward conveyor to the spreading station, at the same time in Double paternoster unit which can be used in a known manner for loading or emptying the press (1 or 5) is arranged, with the removal of the Spangutpreßlinge from the feed plates in each case on the way between the press and the spreading station from the upward conveying double paternoster plant can. 3. Plant according to claim 1 or 2, characterized in that the conveyor line between the location of the removal of the chip compacts from the loading plates and the spreading station (9) is designed as a cooling zone (8) for the feed plates. 4. Plant according to claim 1, 2 or 3, characterized in that for conveying down the Spangutpreßlinge removed from the loading plates another double paternoster plant (7) is provided, which can be designed as a cold store.
