The invention is based on the object of creating a garbage compactor that runs smoothly, flawlessly and virtually Wear-free operation of the well-known garbage compactor guaranteed.

In the case of a garbage compactor of the type mentioned at the outset, this task is thereby resolved in that on opposite longitudinal sides of the compression channel longitudinal slots for the compression piston

are provided on attached pulling arms, / which attack the pull cables that on the inside of the baling channel at a distance to the wall a cover plate covering the slot surface is connected to the duct wall, which from one end into a, protruding parallel to the curve axis running channel-shaped section of the piston from a double-walled area of the piston is formed, wherein the pull arm is attached to the outer wall of the double-armed portion.

In order to keep the baling channel completely free of the output means, the pull ropes attack the pulling arms of the plunger, which in Longitudinal slots are guided in the longitudinal side wall of the press channel. The invention now ensures that garbage is not falls from the press channel through the longitudinal slots to the outside, which cause contamination of the surroundings of the compactor would and, under certain circumstances, also impair the flawless, smooth running of the pulling arms, or even to a jamming of the tension arms in the longitudinal slot would result. The cover plate prevents material from escaping through the Ylong slot. Nevertheless, the Preßkoiben is flawless in the baling channel led, with only a g, pinger air gap between

7501090 03.0E76

J-f A—

There is plunger and channel wall.

The cover plate can either be above or below the Be connected to the longitudinal slot with the Preßkanalwand. It is particularly advantageous to attach it above the Longitudinal slot, since in the other case the gap formed between the cover plate and the duct wall is open upwards, so that Material of small particle size could nevertheless get to the outside to a small extent.

There are various options for attaching the cover plate. An advantageous embodiment of the invention provides in this context that the cover plate is attached to a horizontal guide plate fastened in the longitudinal slot is attached, which is an upper running surface for the pull arm. Instead of cover plate and guide plate from separate To manufacture parts that are then welded together, there is also the advantageous option of integrating them to shape from sheet metal.

A further embodiment of the invention provides for the pulling arms to be guided horizontally both above and below before that in the area of the lower edge of the longitudinal slot a horizontal lower guide plate is attached, the one represents the lower running surface for the pull arm. If the plunger is provided with further guide means through which it is im The compression channel is guided, the guide plates only serve to prevent the compression piston from twisting or tilting.

7501090 O3.0R76

to act.

Since the entire pressing forces are to be transmitted to the plunger via the tension arms, it must be sufficiently rigid for a Attachment of the tension arms on the plunger care must be taken. In this context, a further embodiment of the Invention before that on the outer wall of the double-walled portion of the plunger two parallel, horizontal, spaced support plates are attached, which are guided at a small distance from the guide plates, and that the Pull arms are attached to the support plates. The support plates ensure that between these and the guide plates The smoothest possible run is guaranteed in every position of the plunger. In addition, the support plates secure a rigid attachment of the tension arms on the plunger, since the main torque developed by the tensile forces around a Axis arises that is perpendicular to the plane of the support plates.

Again, the plunger can be designed in any suitable manner. Another embodiment of the To this end, the invention provides that the piston is a hollow body and, in turn, is continuous in the area of the longitudinal slots Has LLngsöffnungen, in which the double-walled, the channel section forming part is inserted, preferably by welding, the outer wall of the double-walled portion preferably made of stronger material than the rest of the piston. It has been found that despite the substantial to be transmitted pressing forces is sufficient, the plunger

7501090 03.oa76

to be designed as a hollow body, as it is made sufficiently rigid can be. As a result, the plunger is not unnecessarily heavy and requires a relatively small amount of material for its Manufacturing. Reinforcing the outer wall of the double-walled section primarily favors a stiff one Attachment of the pulling arms.

A further advantageous embodiment of the invention provides that the tension arms below the through the longitudinal axis extending horizontal plane are attached to the piston. This ensures that the on the face of the Counterforces acting on the plunger have no or only a very small moment about the axis formed by the pulling arms to develop. Such a moment would cause the piston to tilt, which increases the friction of the piston in the channel and can even cause the piston to jam.

The compression channel and the compression piston can be designed in any suitable manner. In this context one sees Another embodiment of the invention that the compression channel and the plunger have a circular cross-section. Through the circular cross-section results in optimal rigidity for the piston and the channel, which is particularly important for the piston is advantageous if it is designed as a hollow body. Basic component for the baling channel and plunger is a pipe of relatively large cross-section.

In a further embodiment of the invention it is provided that the plunger is flattened on the top. It leaves not always avoid that relatively solid objects are in the gap between the plunger and the baling channel wall pinch, so that extraordinarily high forces have to be used to actuate the plunger. By the flattening the plunger, a free space is created in the parts of bulky objects or other relatively stiff parts can evade and thus not particularly impair the stroke of the piston. Because the plunger is double-acting, there is no risk of accumulated material in the space above the flat remains there.

A garbage compactor must of course be of large volume, which is appropriate The diameter of the baling channel and plunger is conditional. The large dimensions and those that arise for this reason large moments on the plunger require satisfactory guidance of the plunger in the baling channel, which is undesirable Friction, inhibition of the piston and also the sticking of garbage in the area of the guide excludes as far as possible. In this context, another embodiment of the invention provides that rollers are attached to the plunger, which roll on the inner wall of the baling channel. With the help of the rollers, the plunger is properly guided without There is a risk that the plunger can jam in the guide due to tilting, tilting, twisting, etc., as is the case with others Management means would be the case. In addition, the inven-

7501090 03.oa76

proper management of extremely little effort, since no precautions have to be taken on the baling channel itself and also the constructive measures on the plunger itself keep within limits. In addition, the guide according to the invention ensures that there is no inhibition of the plunger by the penetration of garbage parts.

This ensures that not even the smallest portion of the garbage to be pressed, but in particular also dust, is removed can emerge the longitudinal slots in the baling channel, provides a further development of the basic idea of the invention that Above the lower guide plate at a distance from a sliding plate is arranged and that between the sliding and guide plate a flexible, preferably elastomeric sealing collar is attached, the free edge of which is attached to the outside the outer wall of the double-walled section of the Preßkolbans and / or rests against the free edge of the cover plate. in the In the area not covered by the piston, the sealing sleeve lies against the free edge of the cover plate and thus closes completely the gap between the cover plate and the baling channel wall. The sealing collar is located in the area covered by the plunger on the plunger. A suitable deflection device, for example a deflector plate, ensures that during the process of the plunger, the flexible sealing collar is deflected in a suitable manner.

7501090 03.oa76

The plunger is driven, as already stated above, with the aid of traction ropes. In this context Another embodiment of the invention provides that a pull arm approximately in the longitudinal center of the plunger on each side is attached, on which two pulleys are rotatably mounted that each pulley pair is assigned a cable drum, the can be driven synchronously by a drive motor that a first cable from the first cable drum via a first lower Deflection pulley at one end of the press channel, a rope pulley of the plunger, a first upper deflection pulley above the first lower pulley, cross pulley to the other side of the press channel, a second upper pulley, a role of the Pull roller pair on the other side of the plunger and a second lower deflection roller under the second upper deflection roller is deflected to the second cable drum, and that a second cable from the first cable drum to the other end of the baling channel guided and deflected in a corresponding manner connected to the second cable drum. With the help of such a The Proßkolben is guided by rope guidance, i.e. the forces that can be applied to the pulling arms by the drive motor are always there evenly distributed, regardless of the pressure forces acting on the end wall of the plunger. This in turn will ensures precise guidance of the plunger in the baling channel.

Another embodiment of the invention provides that the length of the plunger is dimensioned so that it is in the dead center position extends at least as far as the outlet opening, but preferably protrudes somewhat beyond the outlet opening. Since the

7501090 03.0676

Ends of the baling channel attached pulleys should not be arranged beyond the end if possible, because as a result, the loading of a vehicle or a container with compressed waste packages is made more difficult, the plunger must have a minimum length have when he is to push a press package from the press channel into the container in the dead center position. In the dead center position, the plunger preferably protrudes something out of the outlet opening so that the plunger pushes the pack into the container or onto the vehicle can push that loose material at the end of the press pack still falls into the container and not to the outside, if it is removed from the outlet port.

A preferred embodiment of the invention is intended below are described in more detail with reference to drawings.

7501090 06/03/76

As can be seen from FIGS. 3, 6 and 7, the plunger 15 has an elongated, continuous one on opposite sides Opening which is delimited by the edges 18, 19. In this opening 20 a double-walled section is through Fastened weld, which consists of an inner wall part 21 and a stronger outer wall part 22. The inner wall part 21 is welded to the upper edge 18 of the opening 20 via a transverse plate 23. The outer wall part 22 is with the welded lower edge 19 of the piston 15, via a radial, veuältnisstens strong support plate 24, with the the lower edge of the inner wall part 21 is also welded to abutment. With the outer wall part 22 are two spaced, parallel, horizontal support plates 25, 26 welded together, which are used for fastening a bearing journal 27 serve. The bearing pin 27 has corresponding flats 28, with which the support plates 25 and 26 are welded. About it In addition, the bearing pin 27 is welded directly to the outer wall part 22. As can be seen from FIG. 3, the bearing pin is used for the rotatable mounting of rope pulleys 29, 30, 31, 32.

The compression channel 14 is provided with longitudinal slots on opposite sides 33, 34 (Fig. 2), through which the bearing pins 27 are guided to the outside. As in particular from FIG. 6 in more detail to see, extend over the width and the length of the longitudinal slots 33, 34 cover plates 35, which are spaced from the Inner wall of the press channel are attached to this. It is attached by welding to a horizontal one Guide plate 36, which in turn with the free edge 37 in the

7501090 03.0676

Longitudinal slot 33 or 34 is welded. The guide plate 36 is flanged at 38 on the outer edge. A gusset plate 39 ensures that the guide plate 36 is rigidly attached the channel wall of the press channel 14.

A lower guide plate 41 is welded to the lower edge 40 of the elongated slot, the same at 42 on the outside is flanged. A gusset plate 43 ensures that the guide plate 41, flange 42 and press channel 14 are firmly connected. Fig. 6 makes it clear that through the wall parts 21 and 22 a channel extending in the longitudinal direction of the plunger 15 is formed through which the slot cover 35 is guided. In the area of the press channel 14 outside the press piston 15 the slot 33 or 34 is closed by the cover plate 35 except for a small, downward-facing gap. This prevents material from penetrating from the inside of the press channel 14 to the outside. In the area of the plunger 15, the cover 35 is received by the channel-shaped section.

Fig. 7 shows an additional sealing option in which a sealing collar 44 is used, which consists of a leaf spring Part and a sealing part 45 attached to it at the free end. The sealing collar 44 is on one Side between an inverted U-shaped profile 46 which is welded to the guide plate 41 and an angle profile 47 clamped. U-profile 46 and angle profile 47 also extend over the entire length like the sealing collar 44

7501090 03.06176

Length of the longitudinal slots 33, 34. Outside the plunger, the sealing collar 44 can relax somewhat and the Sealing section 45 rests against the lower free edge of the cover plate 35 and prevents any leakage Material, thus also dust, from the press channel 14. In the area of the press barrel 15, however, the sealing collar 44 bent more downwards, which is shown by dash-dotted lines. The sealing collar is in this position 44 against the outer wall portion 22. A suitable deflector, such as a deflector, provides for the fact that when the plunger is moved I * the sealing collar 44 is deflected downward in a suitable manner.

In the longitudinal center plane of the plunger 15 are lying on the underside two rollers 48, 49 arranged at a distance from one another. The rollers 48, 49 are in roller box 5G, which are fixed in the hollow plunger 15, rotatably mounted and roll on the inner wall of the press channel 14. Similarly, sand on both sides of the plunger 15 further rollers 51, 52 are provided. The running and guide rollers 48 to 52 enable precise, low-friction and Perfect guidance of the plunger 15 in the baling channel 14.

At the top, the plunger 15 has a flat 53, which creates a space between the plunger 15 and the bale channel is formed.

Fig. 9 shows a longitudinal section through the plunger 15, the inside with stiffening, unspecified elements

is equipped. The end faces of the piston 15 are closed off by reinforced plates 54, 55. At the top in the In the area of the flat 43, the piston 15 is equipped with a coverable one-man hole.

The bearing journals 27 are attached to the piston 15 below the longitudinal axis of the latter and, as already mentioned above, are mounted on the piston 15. two pulleys 29, 30 or 31, 32. The pulleys up to 32 are made by two ropes, each with rope drums 56, 57 are connected, which in turn are driven synchronously by a common drive motor 58 (Fig. 3). A first rope 59 is connected to the rope drum 57 and is driven over a first lower deflection pulley 60, the rope pulley 30, a first upper deflecting roller 61, a first transverse deflecting roller 62, a second transverse deflecting roller 63 (FIG. 8), a second upper one Deflection pulley 64, the rope pulley 32, a second, lower second, arranged below the second upper deflection pulley 64 Deflection roller to the cable drum 56 (Fig. 3) deflected. In the same way, but in the opposite direction, a Second rope 65 deflected from the rope drum 57 to the rope drum 56. The arrangement of the pulleys and the guide the ropes 59 and 65 ensures that the plunger is moved completely evenly, without tilting, twisting or tilting etc., regardless of the pressing forces acting on its end face.

The ends of the press channel 14 are vertically displaceable Saving shields 66 blocked, the sides in double-T-shaped

- 15 -

7501090 O3.oa76

Support profiles 67, 68 are performed. Guide rollers 69, 70 ensure easy opening and closing of the shield 66. The guide is shown in greater detail in FIGS. 5a and 5b. They show a section through the support 67. The guide rollers 69, 70 ensure that the shield 66 is precisely positioned adjustable in a single vertical plane.

The shield 66 is adjusted by a drive device 72 which is arranged on a console 71 on the support 68. Details of the drive are also not discussed here.

In operation, a waste compactor is between the corresponding end face of the piston 15 and the corresponding shut-off shield formed, which with the shield open with the help of the plunger in a provided or flanged Container or a provided vehicle can be pushed. For this purpose, the plunger 15 is in its length dimensioned so that it protrudes somewhat in its dead center position over the level of the shut-off shield, so that the press package is inserted far enough so that loose material falling at the rear end does not fall on the floor. Operational ensures the cable guide described for a proper displacement of the plunger 15 in the baling channel 14, regardless of the attacking press forces. The flat 53 enables bulky parts to be avoided, which reduces the drive effort considerably reduces.
