Definitions

• the invention relates to a compacting press according to the preamble features of patent claim 1.
• Compacting presses designed as briquetting presses are known from DE-PS 33 33 766 and DE-A-30 38 839.
• a pre-compressor piston is connected upstream of a horizontally movable plunger.
• Pre-compression chamber into which the pre-compression piston is immersed, is fed by a feed device, e.g. B. fed a feed screw.
• the horizontal press ram compresses the slightly precompacted material in a downstream, disk-shaped molding tool that has several molding chambers.
• the rear end of the rotatable mold is closed off as a counter pressure plate by a fixed end plate against which the horizontal ram compresses the material to be pressed.
• a briquette pressed in a previous pressing process is ejected from the disk-shaped molding tool and then removed by a stacking device, for example a conveyor belt.
• the known compacting press Due to the horizontally arranged ram, the known compacting press has a large footprint, which is of secondary importance in industrial use for compacting leaves or wood waste.
• the footprint plays a primary role, as does the possibility of temporarily storing a large number of compacts in a space-saving manner.
• a generic compacting press is known from US Pat. No. 3,651,755 and in a similar form from US Pat. No. 3,563,164.
• WO 93/19930 also describes a compacting press which, however, has no collecting container for the intermediate storage of the compacts.
• DE-U-76 36 727 a household press for cans or bottles is also known, but only a destruction the bottles or cans by means of a piston falling under its own weight, but does not cause permanent deformation and compression.
• all of these devices have a large space requirement or space-consuming construction in comparison to the possible intermediate storage capacity.
• presses which, after being shredded, compress the paper strips in a horizontal extruder and eject them laterally into a container.
• a considerable footprint is required, because in addition to the approx. 1.5 m long pressing device, a container with about half a cubic meter of capacity is set up so that the container does not have to be emptied too often.
• the object of the invention is to create a compacting press which has a small footprint and thus enables the most compact possible dimensions with a high compression density.
• the press ram By arranging the press ram in the vertical direction over a compact container for the intermediate storage of the shaped compacts, a small footprint is achieved, which is essentially determined only by the base area of the container for the intermediate storage of the compacts.
• the compact container takes up about a third of the overall height of the compacting press, so that there is a capacity of about half a cubic meter.
• the compacting press is still easy to transport due to its compact design.
• the desired high pressing density is achieved in that the molding chamber is closed in the pressing position by a closure slide which can be displaced in the horizontal direction. At the Pushing the compact thus compacted in the molding chamber through the press die itself does not require a separate ejection device, so that the construction effort for the compact compacting press remains low.
• the closure slide has on its underside one or more drivers which, when the compact container is filling, laterally convey the compact away and thus achieve complete filling of the compact container.
• the compact collecting container is designed as a rolling container with a capacity of up to approximately half a cubic meter, so that emptying only rarely takes place due to the high compression density and the complete filling of the container. This creates an overall compacting press that is particularly suitable for applications in offices as a replacement for document shredders or shredders, whereby several conventional cutting rollers can also be expediently provided in the area of the feed chute or the feed device.
• the lateral inlet opening to the molding chamber is designed asymmetrically or eccentrically with respect to the press ram axis, so that a torque is exerted on the press ram during the press movement about the upright axis of the press ram, so that the latter rotates and thus the cutting edge on the bottom of the press ram wears evenly.
• This achieves a particularly long service life of the cutting edge on the lower edge of the ram for shearing off the material to be pressed during the transition from the lateral inlet opening to the molding chamber itself.
• Figure 1 is a perspective view of a compacting press.
• Fig. 2 is a front view of the compacting press partially in
• Fig. 3 is a plan view in section along the line
• FIG. 4 shows a side view of the compacting press according to the
• a compacting press 1 is shown schematically in a perspective view, the paper to be pressed, for example from old files, being filled essentially from above into a feed shaft 2.
• conventional cutting rollers 25 of a shredder can also be provided (see FIG. 2), so that the paper to be pressed is cut into strips.
• a feed device 3 is provided in a horizontal orientation, for example a screw conveyor or a feed helix, which conveys the paper material through a lateral inlet opening 7 into a molding chamber 6, above which a press ram 4 that goes up and down in the molding chamber 6 and a press cylinder 5 is arranged, which are shown in more detail in Fig. 2.
• the press ram 4 After feeding the paper material through the lateral inlet 7, the press ram 4 is lowered several times by acting on the press cylinder 5, the paper material being compressed.
• a lower outlet opening 8 of the mold chamber 6 is closed by a slide slide 9 which can be displaced in the horizontal direction.
• the closure slide 9 is guided in a built-in slide guide 10 (cf. also FIG. 4) and is driven back and forth in the horizontal direction by a slide drive 11, preferably also with a hydraulic cylinder. The drive takes place after reaching a certain pressing volume.
• the closure slide 9 has a slide opening 12 which has a cross section of the Mold chamber 6 has a corresponding diameter or slightly larger.
• the slide opening 12 coincides with the outlet opening 8 of the for chamber, so that a compact 21 pressed in each case in the molding chamber 6 is ejected through the downwardly moving ram 4 and down into a compact container 20 can fall.
• the uppermost compacts 21 are conveyed away to the side by each return stroke of the closing slide 9 and one or more drivers 13 arranged on its underside, so that a complete filling of the compact container 20 is achieved.
• the slide unit is mounted on a slide frame 14, which is preferably flanged to the housing of the molding chamber 6, in order to achieve reliable support of the forces when the slide slide 9 is moved.
• This slide frame 14 is arranged essentially below the area of the feed device 3, the bottom of which at the same time forms a cover for the slide frame 14 and can additionally stiffen it.
• the feed device 3 is driven by a drive motor 15, which is also laterally attached to the slide frame 14 and is designed in an appropriate embodiment as an electric motor, which, if necessary, for. B. is switched on at a certain level in the feed chute 2.
• the press cylinder 5 or the press ram 4 is in this case operated by a hydraulic pump 17 which is driven by a drive motor 16.
• the drive motor 16 and the hydraulic pump 17, which is preferably designed as an internal gear pump, are preferably surrounded by a sound insulation capsule, so that the compacting press 1 operates with little noise. This also contributes if the press cylinder 5 has a pressure booster 18 connected to the hydraulic pump 17 and laterally connected for a small overall height at its upper end, so that low connected loads are required.
• the activation of the known pressure intensifier 18 and the Slider drive 11 is carried out by a displacement transducer 19, which is preferably arranged in the center of the press cylinder 5 and detects the depth of the plunger 4 that can be reached in each case.
• FIG. 2 shows a front view in partial sectional view of the compacting press 1, the corresponding components described in connection with FIG. 1 being provided with the same reference numerals.
• This shows in particular the compact design of the press, in particular the small space requirement for a compact container 20 which has a relatively large holding capacity for the compacts 21.
• the compact container 20 can be pulled out on the front of the compacting press 1 facing the viewer (arrow D in FIG. 3), a lower frame part 30 being open towards the front, so that the compact container 20 is opened after pivoting doors are opened 23 according to arrow C in Fig. 3 in the manner of a roll container after complete filling can be easily removed from the press unit and emptied.
• the lower frame part 30 is preferably constructed from square tubes, which also serve as an oil reservoir for the hydraulic oil.
• the block-shaped housing 31 for the molding chamber 6 is formed, in which the lateral inlet 7, the lower outlet 8 and the slide guide 10 are incorporated (cf. FIG. 4).
• This block-shaped housing 31 is also flanged to the side of the slide frame 14 and vertical tie rods 32 are fastened on the upper side by means of fastening bores 33 to support the press cylinder 5.
• FIG. 3 shows the top view along the section line AA in FIG. 2.
• the solid design of the housing 31 for the molding chamber 6 and the slide unit connected to it laterally with the slide frame 14, the slider drive 11 mounted thereon and the closure slider 9 actuated therefrom with the slider opening 12 are shown.
• the slide valve 9 is in the closed position for the molding chamber 6. After the material to be pressed is filled through the lateral inlet opening 7, the press ram 4 moves down into the molding chamber 6 and thus compresses the material to be pressed, in particular the waste paper.
• the depth of immersion in the mold chamber 6 that can be achieved by the press ram 4 becomes ever smaller, which is determined, for example, by the displacement transducer 19, but can also be determined by pressure sensors or external displacement measuring systems.
• the slide drive 11 is actuated, the slide opening 12 being displaced to the left in accordance with FIG. 2, so that it corresponds to the lower outlet opening 8 arrives.
• the compact 21 formed in the molding chamber 6 is thus pushed down out of the molding chamber 6.
• the subsequent return stroke of the slide valve 9 when the mold chamber 6 is re-closed at the same time, the compact, which may still be located in the left region of the compact container 20, is pushed sideways to the right, so that the compact container 20 can be completely filled.
• the associated side view of the housing 31 for the molding chamber 6 is shown.
• the guidance of the closure slide 9 in the slide guide 10 and the relatively simple construction can be seen.
• the driver 13 which projects downward into the compact container 20 and is arranged on the underside of the closure slide 9, is shown, which serves for the lateral transport away and thus the most complete filling of the compact container 20.
• the asymmetrically designed lateral inlet opening 7 through which the feed device 3 conveys the material to be pressed, in particular the waste paper, into the molding chamber 6.
• this rotary bearing 4b can also be dispensed with, since the plunger assigned to the plunger 4 can rotate in the press cylinder 5 anyway. It should be noted that this type with a gradual rotation of the ram is of special, independent importance due to the asymmetrical design of the inlet opening and can therefore also be used on other compacting presses.
• the two side plates are securely fastened to form the slide frame 14, which are flanged to the housing 31 of the molding chamber 6, which is designed as a block, with several screws (cf. also Fig. 2 along the section line BB) and thus result in a particularly stable design, especially since the other load parts, namely the tie rods 32 and slide guide 10 are attached or formed thereon.
• the inlet opening 7, which is asymmetrical with respect to the central axis of the molding chamber 6, is through the one in the lower right Area opposite the circular shape radially expanded outer shape cam-shaped, other shapes are also possible, for. B. an off-center offset or an elliptical shape of the inlet opening 7th
