Definitions

  • the invention relates to a press emptying device, consisting of a vertically movable press emptying basket with chain conveyor device and a plurality of supports arranged on the long sides of the press emptying basket with a slot area for press supports for a multi-day press, a discharge device arranged in the slot area for particle boards passed in succession from the press emptying basket.
  • Press emptying devices are arranged behind multi-daylight presses in order to enable the multi-daylight press to be emptied as quickly as possible after completion of the pressing process and to carry out further conveying of finished pressed chipboard in continuous operation regardless of this.
  • the finished pressed chipboard including its documents from the press are stored in a press emptying basket and then fed from this to a separation station arranged behind the press emptying basket, in which a separation between the pressed particle board and documents takes place, with flexible documents the flexible documents after the separation are fed back by a downward conveyor to a return conveyor which returns the documents freed from the chipboard to the pouring station (DE-A-16 53 319)
  • the invention has for its object to use a press emptying basket at the same time as a separating device for separating finished pressed chipboard, its flexible documents and as a downward conveyor for the empty flexible documents to be removed.
  • a cage which is open in a vertical direction is provided, and that for each chipboard and each associated press pad there is an associated chain conveyor pair which uses a roller conveyor for removing chipboard and for storing the flexible press pads peeled off the chipboard in the middle there is also an open auxiliary deck, and that a return device is arranged below the cage for the return of peeled flexible press documents.
  • This inventive solution completely avoids additional separation, a downward conveyance and a conveyance to the return conveyor for flexible documents, as the state of the art absolutely had to have; a peeling process, which simultaneously leads to a return process, is thus achieved within the press emptying device.
  • the cage is U-shaped and open at the bottom. This configuration enables the removal of the removal conveyor directly on the foundation, and the U-shaped cage can be moved past this conveyor.
  • a drum-like cladding be provided in the region of the deflection of the chain conveyor. This cladding is used in particular to cleanly guide the flexible base to be peeled off.
  • guides are arranged in the region of the deflection of the chain conveyor. As a result of the arrangement of guides, the documents are deflected securely without the free end of the documents causing the chipboard to be removed from being destroyed in the event of a rush.
  • At least the lowest pair of chain conveyors be provided with an auxiliary deck in the area of its returning dreams.
  • the arrangement of an auxiliary deck has the considerable influence that the headers of the flexible documents can be taken over by the removal device in a well-positioned position.
  • pinch rollers with a roller conveyor are arranged behind the separation point. Thanks to the use of the pinch rollers rotating at an adjustable speed, the finished pressed chipboard can be transported continuously despite the discontinuous unloading and cutting.
  • a press emptying device consisting of a press emptying basket 1, in which chain conveyor pairs 3, 4, 5 are arranged, and in which a discharge device 6 is provided, is located between a schematically illustrated three-day press 2 and a roller conveyor 8 with at least one pinch roller pair 9.
  • the press emptying basket 1 also has a feed device 10, which is only shown in FIG to bring the finished pressed chipboard 11, including flexible documents 12, into the area of influence of the chain conveyor pairs 3, 4 and 5.
  • the chain conveyor pairs 3, 4 and 5 have drivers 13, with which they can grip behind headers 14 of the flexible documents 12.
  • all flexible documents 12 provided with particle boards 11 are simultaneously moved onto the chain conveyor pairs 3, 4, 5.
  • all pairs of chain conveyors, which are to be regarded as tiers of the press emptying basket 1 at the same time are covered with flexible documents 12 which carry the chipboard 11, a peeling process and the simultaneous return process of the flexible documents 12 are then carried out, as shown in FIG. 1 b.
  • the chain conveyor pair 5 which, together with decks 21 as supports for the flexible documents provided with chipboard 11, forms the bottom floor of the press emptying basket 1 is set in motion by a motor, not shown.
  • the headers 14 of the flexible documents 12 are guided from the drivers 13 arranged on the chain conveyor pair 5 to the drive sprockets 24.
  • the area between the chain conveyor 5 arranged on the left and the right side of the press emptying basket 1 is provided with a drum-like cladding 25, which on the one hand protects the connecting and drive shaft of the drive sprockets 24, and on the other hand serves as a sliding support for the flexible support 12 .
  • chipboard 11 and flexible base 12 are thus necessarily separated from one another, as shown in FIG. 1b.
  • the chipboard 11 is taken over by squeeze rollers 9 and fed to a roller conveyor 8 for further processing, the flexible base 12 is moved with the returning strands 27 of the chain conveyor pair 5 onto an auxiliary deck 15 and deposited there; then the drive motor of the chain conveyor pair 5 is braked.
  • the press emptying basket 1 is lowered by one level, so that the chain conveyor pair 4 now empties and separates the next floor from the chipboard 11 and the flexible base 12, as described above for the bottom floor.
  • the pair of chain conveyors 5 with their decks 21 themselves can serve as an auxiliary deck for the intermediate storage of the peeled flexible base 12.
  • FIG. 1 c illustrates how the flexible documents 12 are transported back after the press emptying basket 1 has been emptied.
  • the bottom floor has come into the effective area of the removal device 6 with the flexible base 12 resting on the auxiliary deck 15.
  • the discharge device 6 is driven by a drive motor, not shown, in the direction of the arrow and thus takes over the flexible documents 12, which are initially behind with their head strips 14 by the drivers 13 of the chain conveyors 3, 4 and 5.
  • the removal device 6 transfers the flexible base 12 to another return conveyor belt, from which the flexible base is brought to a pouring station, not shown, for re-loading with new chip material.
  • a cross-section along line AA is represented by the Pressenentleerkorb 1, in which the Pressenentleerkorb 1 is shown as shaped U-downwardly open cage 25 in which the chain conveyor pairs 3, 4, 5, the three storey represent available are and where the returning dreams 27 of auxiliary decks 15 are undercut.
  • the discharge device 6, which is arranged on a base 17, which is. : supported on a foundation 18, shown.
  • the removal device 6 can move up in a slot 19 relative to the downward moving press emptying basket and convey the individual flexible documents 12 away.
  • the removal device 6 is expediently designed as a belt conveyor.
  • removal of the flexible documents 12 by the removal device can already begin when the first flexible base lies on the auxiliary deck 15.
  • the removal does not take place here, as shown in FIG. 1, when all floors have been emptied, but only shifted by one cycle with respect to the separation. The time saved is obvious.
  • the end 20 of a flexible base 12 shown in dashed lines in FIG. 1 c is intended to illustrate the prevention of this end from flipping up by the guide 16 which is arranged above each pair of chain conveyors.
  • decks 21 are provided which, like the auxiliary decks 15, protrude inward only over a certain width of the press emptying basket 1, so that the slot 19 is clearly created, in which a relative movement between the removal device 6 and the press emptying basket can take place .
  • the chain conveyor pairs 3, 4 and 5 are arranged outside the decks 21 and auxiliary decks 15. It can be clearly seen from FIG. 1 d that the discharge device 6 ends with a deflection 23 before the deflections of the chain conveyor pairs 3, 4 and 5, since the shafts are driven over the full width of the press emptying basket for driving these chain conveyor pairs.
