Filling device and filling method

A baling press for fibrous material, the baling press comprising:

• a fiber feed;
• a pressing device comprising a press shaft;
• a filling device arranged between the fiber feed and the pressing device, wherein the filling device comprises:
• a collecting chamber for the fibrous material with a feed opening as well as with a discharge opening directed to the press shaft;
• and with
• an integrated precompacting device comprising a driven slide comprising an upright slide wall reverseably movable between the openings, the precompacting device being configured to collect the fibrous material in the collecting chamber and precompact the fibrous material in the collecting chamber with movement of the slide with a compaction stroke in one or more stages;
• and
• a controllable closure arranged at the discharge opening directed to the press shaft, wherein:
• the controllable closure closes the discharge opening during the compaction stroke of the slide;
• the collecting chamber is arranged horizontally or obliquely;
• the slide is arranged in the collecting chamber and reverseably moves along a chamber bottom between the openings;
• the precompacting device comprises an enlargement of the collecting chamber with a collection area and with a compaction area arranged downstream, which collection area and compaction area are arranged behind one another in a direction of feed of the slide;
• the collection area and the compaction area are arranged in a closable chamber housing of the collecting chamber;
• and
• the feed opening is arranged above or on the side of the chamber housing and the discharge opening is arranged at a front end of the chamber housing.

A filling method for fibrous material on a baling press by means of a filling device, which is arranged between a fiber feed and a pressing device comprising a press shaft, the method comprising the steps of:

• feeding the fibrous material through a feed opening into a collecting chamber of the filling device and discharging fibrous material through a discharge opening to the press shaft of the pressing device, wherein the fibrous material in the filling device is moved with a driven slide that comprises an upright slide wall and moves in a reversing manner between the openings;
• collecting the fibrous material in the collecting chamber by means of an integrated precompacting device of the filling device;
• and
• precompacting collected fibrous material in the collecting chamber with the moving slide in one or more stages, wherein the collecting chamber is provided with a controllable closure for the discharging of the precompacted fibrous material to the press shaft through the discharge opening, which is provided with the controllable closure, wherein:
• the controllable closure closes the discharge opening;
• the collecting chamber is arranged horizontally or obliquely;
• the slide is arranged in the collecting chamber and moves in a reversing manner along a chamber bottom between the openings during a compaction stroke of the slide;
• the precompacting device collects the fibrous material, which has been fed in a plurality of batches, and precompacts the fibrous material with a plurality of strokes of the slide in the collecting chamber;
• and
• the fibrous material is retained with a retaining device in the collecting chamber during the precompaction.

A filling device for fibrous material on a baling press, wherein the filling device is configured for an arrangement between a fiber feed and a press shaft of a pressing device of the baling press, the filling device comprising:

• a collecting chamber for the fibrous material with a feed opening as well as with a discharge opening directed to the press shaft;
• an integrated precompacting device comprising a driven slide comprising an upright slide wall revereably movable between the openings of the collecting chamber, the integrated precompacting device being configured to collect the fibrous material in the collecting chamber and precompact the fibrous material in the collecting chamber with movement of the slide with a compaction stroke in one or more stages;
• and
• a controllable closure arranged at the discharge opening to the press shaft, wherein:
• the controllable closure closes the discharge opening during the compaction stroke of the slide;
• the collecting chamber is arranged horizontally or obliquely;
• the slide is arranged in the collecting chamber and is revereably movable along a chamber bottom between the openings;
• the precompacting device comprises an enlargement of the collecting chamber with a collection area and with a compaction area arranged downstream, which collection area and compaction area are arranged behind one another in a direction of feed of the slide;
• the precompacting device comprises a retaining device for retaining the fibrous material, which retaining device is arranged between the collection area and the compaction area;
• and
• the retaining device comprises a plurality of retaining arms, which are movable and capable of dipping into the collecting chamber in a reversing manner, as well as a controllable drive.
