DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a compacting press for compacting paper material and, more particularly, a compacting press for office use having a small footprint and large storage capacity.
DESCRIPTION OF THE PRIOR ART
Compacting presses in the form of briquette presses are known from DE-PS 3 333 766 and DE-A 3 083 839. A precompression piston is here disposed ahead of a press ram movable horizontally to and fro. The precompaction chamber, into which the precompaction piston extends, is fed by a feeder mechanism, e.g., a feeder auger. The horizontal press ram compacts the material which has thus been slightly precompactcd into a following molding die of disc form, with a plurality of molding chambers. The rear end wall of the rotatable molding die is closed off by a fixed back-plate as a counter-pressure plate against which the horizontal press ram compacts the pressing material. In this known apparatus a briquette compacted in a preceding press operation is ejected from the disc-shaped molding die and then taken off by a stacking device, for example to a conveyor belt.
On account of the horizontally arranged press ram, the known compacting press has a large footprint, which is of little importance in industrial use for compacting leaves or wood waste. For use as a compacting pressure for scrap paper or waste paper in a domestic or office environment however, the footprint plays an important role, as does the ability to provide space-saving interim storage of a large number of pressed parts.
A compacting press of the kind defined is known from US-PS 3 651 755 an in similar form from U.S. Pat. No. 3,563,164. Furthermore, a compacting press is described in WO 93/19930 which does not have any collecting container for interim storage of the pressed parts. In addition, a household press for cans or bottles is known from DE-U 76 36 727, which however only effects destruction of the bottles or cans by means of a piston falling under its own weight but does not provide any permanent forming and compaction. All these apparatuses however have a larger demand on footprint or a space-hungry construction in comparison with the possible interim storage capacity.
Furthermore, presses have been disclosed in the further development of paper shredders or so-called file destroyers, which pass the paper through cutting rollers and then pass it without compaction into a bag, these presses compacting the strips of paper after the chopping in a horizontal extrusion press and eject them sideways into a container. Although further compaction of the strips of paper is thus achieved, a significant footprint is needed, since as well as the press apparatus approximately 1.5 m long, a container is set up with a capacity of around half a cubic meter, so that the container does not have to be emptied too often.
SUMMARY OF THE INVENTION
Accordingly, the invention is based on the object of providing a compacting press which has a small footprint and thus facilitates the most compact dimensions with a high pressing density.
In one embodiment, the present invention provides a compacting press for compacting material, especially scrap and waste paper, comprising, a frame having a footprint, a feed chute mounted on the frame for receiving material to be pressed, a molding chamber mounted on the frame, and a feed device horizontally arranged on the frame for transferring the material from the feed chute to the molding chamber. A press ram arranged along a vertical axis compacts the material in the molding chamber. A container disposed within the footprint of the frame and below the molding chamber receives the pressed material, and a closure slider arranged between the molding chamber and the container is reciprocal between a first position closing the molding chamber from the container and a second position opening the molding chamber to the container.
By arranging the press ram in the vertical direction above a pressed part container for interim storage of the shaped pressed parts, a small footprint is obtained, whic
