Definitions

  • the invention relates to a baling press for compacting cardboard, leaves, grass or other dispensable waste materials according to the preamble of patent claim 1 and to a method for controlling such a baling press according to the preamble of patent claim 13.
  • the DE 10 2009 053 134 A1 a horizontally operated baler with an ejection piston.
  • the container press housing essentially consists of five side walls that are firmly connected to one another and a floor that rests on the ground, which together enclose a cuboid press chamber.
  • a filling opening is worked into the side wall opposite the bottom, through which the loose or isolated waste material can be transferred or filled into the pressing chamber from a collection container.
  • the waste material is collected in a mobile container and once the container is filled with sufficient waste material, it is moved to the baler to be emptied.
  • a lifting and tipping unit is attached to the front or side of the baler housing, which can be coupled to the respective container.
  • the container must be inserted into the lifting and tipping unit manually.
  • Such a lifting and tipping unit articulated on a baler is the EP 2 537 688 B1 refer to.
  • This lifting and tipping unit is provided on the front side of the baler housing and has a U-shaped bracket to accommodate the respective containers up. Due to the orientation of the bracket, the container can be moved in or out of the mounting bracket transversely or perpendicularly to the pressing direction.
  • a press ram In the pressing chamber of these two baling presses described, a press ram is used, which is fastened to a side wall projecting perpendicularly from the ground and is consequently supported on this. The free end of the ram plunges into the pressing chamber and moves horizontally, i.e. parallel to the ground, resulting in the horizontal pressing direction.
  • the press ram is to be moved axially so that it exerts a predetermined pressing force on the waste material that has been filled in, as a result of which it is compacted. As many air pockets as possible should be squeezed out of the waste material by the pressing process.
  • a wire is inserted into the baling chamber and wrapped around the compacted waste material. The free ends of the inserted wire, which protrude towards each other, are then knotted so that the compacted waste material is strapped and the bale can be removed for transport from the baling chamber.
  • the bale is usually removed by an ejection piston arranged on the press ram, through which the bale is pushed out of the baling chamber through the open door.
  • Garbage trucks have been in use for decades to empty roadside containers filled with waste material.
  • Garbage trucks of this type usually have a receiving and compacting chamber into which the emptied waste material is poured by a lifting and tipping unit attached to the garbage truck. Inside the press chamber, a bale is formed from the waste material that has been filled in and pressed there.
  • baling presses have a considerable longitudinal extent, since the press ram and the ejection piston are arranged in a row, i.e. one behind the other, and the complete ones are between the side wall supporting the press ram and the press ram To arrange drive units for the movements of the ram, which consequently run inside the baler housing.
  • the lifting and tipping unit for moving the containers filled with waste material must be attached to the front of the baler housing, which further increases the length of the baler, since the U-shaped bracket for receiving the containers has a predetermined width to accommodate the To grasp containers in the longitudinal direction of the baler.
  • baling presses often have a length of 6 m and a width of 2 m, so that the required floor space is around 12 m 2 .
  • access must be kept clear in order to couple the containers to the lifting and tipping unit or to remove them.
  • balers are mostly to be set up in storage areas of grocery stores where the available space is limited and is also required for other activities, such as storing and unpacking groceries, or other components required for the operation of the grocery store, the requirement arises that the required space is required , in particular to limit the footprint and access to the baler as much as possible and to locate it in an area that is often against a wall of the warehouse.
  • baling press of the type mentioned at the outset in such a way that, while maintaining the required pressing force and the volume of waste material to be compacted, the length of the baling press must be as small as possible in order to keep the footprint of the baling press as small as possible or this to build compact.
  • the press ram has a press plate that is axially movably mounted in the press chamber and at least one press cylinder, and that the respective press cylinder is arranged on an outside of one of the side walls or on the outside of the base and is coupled to the press plate by means of a connecting element, so that such horizontally operated balers retain their previous technical advantages, but the footprint, in particular the linear expansion of the baler with lifting and tilting Unit builds significantly shorter, since the arrangements of the required parts and components is made from the longitudinal orientation in the width and a spatial overlap of these components is created.
  • the swung-out flaps initially bridge the gap between the press plate and the bale and can exert an ejection force on the bale, which pushes it out of the baling chamber into the open, since the length of the swung-out flaps in roughly equal to the length of the bale.
  • the arrangement of an ejector piston can be completely dispensed with and the required or desired compact construction results from the direct contact of the pivoted-in flaps on the pressing plate.
  • the press cylinder Due to the external arrangement of the press cylinder as part of the press ram, it is advantageously ensured that the length of the baler is reduced, because the parts, media and components required for driving and filling the press cylinder can be arranged, for example, between the underside of the floor of the baler housing and the ground and the spatial series connection of press cylinder and press plate is cancelled.
  • the press plate can namely directly on the rear side wall of the baler housing be arranged in their starting position and thus release the filling opening in the spatially overlying side wall.
  • the volume of the baling chamber is thus maintained in comparison with known balers so that a given sufficient volume of waste material can be compacted to produce a bale having a given size and volume.
  • the press cylinders are positioned on the side of the baler housing, so that the containers filled with waste material can be moved up to the rear of the baler housing and the lifting and tipping unit is mounted directly on the baler housing.
  • the lifting and tipping unit protrudes slightly beyond the rear area of the baling press housing, so that this assembly measure achieves a further reduction in the length of the baling press.
  • the connecting elements arranged between the press plate and the respective press cylinders have an S- or Z-shaped cross section, the free ends of the press cylinder protrude significantly beyond the starting position on the press plate, so that a spatial overlapping of the movement of the press plate and the Press cylinder is created. Such an expansion of the installation space in width reduces the linear expansion of the baling press according to the invention.
  • the press plate and compaction cylinders exert a further compressive force on the compacted waste material until at least one loop of wire encircles the thus compacted waste material. Thereafter, the press plate can be withdrawn from the bale thus strapped without the waste material falling apart or the size of the bale being changed and at the same time the flaps attached to the surface facing the bale can be swung out, thereby bridging the gap between the press plate and the bale is.
  • the container or waste container can be locked with a coupling part of the lifting and tipping unit for emptying and the coupling part is lifted by a pressure piston assigned to the lifting unit and due to further mechanical measures, the coupling part moves along a circular path by almost 180° in the direction of the Filling hole machined into the baler body. Accordingly, the container is raised and at the same time pivoted in the direction of the filling opening, so that the waste material collected in the container falls out of it into the filling opening due to the prevailing gravity.
  • the horizontally movable press cylinder is to be actuated to compress the waste material filled into the press chamber, which advantageously increases the distance between the side wall and the press plate at the same time.
  • the positions or operating states can be queried or recorded by means of sensors that are arranged on the press ram, the pressure piston or press cylinder and the existing doors. This serves as a safety measure to avoid accidents or damage and at the same time such generated switching signals ensure the control of the baler in a fully automatic process.
  • baling press 1 through which loose waste material, for example in the form of cardboard, paper or other compressible components, is pressed into a cuboid bale which is strapped with two wire loops in order to prevent the individual components of the bale from falling apart.
  • the baler 1 consists of a baler housing 2, which is formed by five side walls 3, 4, 5, 6 and 7.
  • the baler housing 2 also has a base 8 placed on a base 9 , so that the five side walls 3 , 4 , 5 , 6 and 7 and the base 8 form a cuboid press chamber 10 .
  • a filling opening 12 through which the waste material 20 can be filled through the filling opening 12 into the pressing chamber 10 , is provided opposite the bottom 8 and opening into the pressing chamber 10 .
  • the waste material 20 is usually collected in a mobile container 14 in a warehouse and as soon as the volume of the container 14 is filled with a sufficient quantity of waste material 20, the container 14 on the baler 1 should be able to be emptied in order to collect the waste material 20 in a to press a wire loop 41 strapped bale 40.
  • a press ram 11 is provided, which consists of two press cylinders 22 and 23 and a press plate 21 which is drivingly coupled to the two press cylinders 22, 23 and is mounted axially movable within the press chamber 10.
  • the two press cylinders 22 and 23 are attached to the outside of the respective side wall 5 or 6 and partially protrude beyond the rear area of the baler 1 formed by the side wall 3 .
  • the protruding press cylinders 22, 23 arranged on the baler housing 2 in this way there is a free space that is dimensioned slightly larger than the width of the baler housing 2, so that the container 14 can be retracted or pushed in between the press cylinders 22, 23.
  • a lifting and tipping unit 13 which consists essentially of a pressure piston 15 and a support plate 16, which is designed as a coupling part for the container 14 and is used for receiving and coupling the container 14, the container 14 from a coupling position along a Be pivoted in a circular path in the direction of the filling opening 12, so that when the end position is reached, the waste material 20 filled in the container 14 is poured through the filling opening 12 into the pressing chamber 10 due to the prevailing gravity.
  • This arrangement of press cylinders 22, 23 and the lift and tilt unit 13 reduces the length of the baler 1, because the press cylinders 22, 23 run partially to the side next to the lift and tilt unit 13.
  • FIG. 2a two positions of the press cylinders 22 and 23 can be seen.
  • the upper position of the press cylinder 23 should represent the initial position of the press plate 21 in relation to the spatial arrangement within the press chamber 10 and the lower position of the press cylinder 22 should represent the maximum possible axial movement of the press plate 21 .
  • the connecting element 24 between the press plate 21 and the two press cylinders 22 and 23 is designed such that a free end of the connecting element 24 is connected to the free end of the respective press cylinder 22 or 23 and the opposite free end of the connecting element 24 is connected to the press plate 21.
  • the respective connecting element 24 has an S or Z-shape in cross section, which enables a spatial arrangement for the pressing plate 21 that is spatially in front of the free ends of the pressing cylinders 22, 23 in relation to the pressing direction.
  • the press cylinders 22, 23 are therefore arranged laterally next to the press plate.
  • the press cylinders 22 and 23 are arranged on the outside on the side wall 5 or 6, so that the length of the baler housing 2 is considerably reduced compared to the known baler housings, since all the installation space for accommodating the press cylinders 22 and 23 within the baler housing 2 is eliminated.
  • a storage tank 35 for receiving a medium is arranged on the underside of the floor 8 , which accordingly runs between the floor 8 and the subsoil 9 .
  • the operating position of the press cylinders 22, 23 can be regulated by means of lines 17 shown schematically and a control unit 33, and the medium can be filled from the storage tank 35 into a corresponding volume range of the press cylinders 22, 23, so that the press cylinders 22, 23 move back and forth axially, whereby the actuation of the pressing plate 21 can be regulated by means of the control unit 33 as a function of the desired position in relation to the waste material 20 introduced into the pressing chamber 10 .
  • FIG 4 the initial situation for filling the pressing chamber 10 is shown.
  • the filling opening 12 is released. This can be closed by means of a door 28 which is pivotably mounted on the side wall 4.
  • a pressure piston 32 is provided between the door 28 and the side wall 4, through which the door 28 can be opened or closed by the control unit 33.
  • the side wall 7 there is an opening 36 which is closed by a further door 37 or, as explained in more detail below, is released in order to remove the bale 40 from the baling chamber 10 .
  • the lifting and tipping unit 13 is in the starting position, so that the support plate 16 is aligned vertically in order to be able to couple the container 14 .

The door 28 can then be opened to pour further waste material 20 into the baling chamber 10 . The operation of the door 28 can be repeated many times.
  • the pressing plate 21 could already exert a pressing force on the waste material 20 filled into the pressing chamber 10 in order to compress the waste material 20 and move it out of the area of the filling opening 12 .
  • the door 37 on the side wall 7 is closed and acts as a stop for the pressing force of the pressing plate 21.
