Definitions

  • the invention relates to a baling press for compressing loose waste material into a bale strapped with at least one wire loop according to the preamble of patent claim 1.
  • balers are well known.
  • a baling press with a vertically movable ram is known, through which such waste material is compacted and pressed into a bale strapped with a wire loop.
  • the ram therefore moves in the vertical direction within the bale chamber and acts on the waste material that is filled into the bale chamber from the outside until the waste material has been pressed to the desired size of the bale.
  • the problem with all baling presses is to transfer the waste material into the baling chamber as quickly and easily as possible.
  • the waste material to be compressed which occurs, for example, in grocery stores in the form of cartons, packaging paper or foil, is first collected in mobile containers, trolleys or the like.
  • the container volume is filled with the waste material to be baled, the respective operator moves the container to the baling press.
  • the container is to be connected to a lifting and tipping device, for example from the EP 20 175 714.3 has become known.
  • the container or waste container is therefore lifted off the ground by the lifting and tipping device and is moved in the direction of a filling opening which opens into the press chamber and is pivoted about the horizontal axis.
  • the open end of the container first comes in the direction of the filling opening and points to the ground, as a result of which the prevailing gravity acts on the waste material, so that it falls out of the container through the entry opening into the compaction chamber.
  • the container must then be lowered and decoupled from the lifting and tipping device so that another container can be connected to it.
  • the press ram is actuated and exerts a pressing force on the waste material that has been filled in, whereby it is compacted and, when the predetermined volume is reached, pressed to the desired size of the bale.
  • a pressing force On the waste material that has been filled in, whereby it is compacted and, when the predetermined volume is reached, pressed to the desired size of the bale.
  • Often several containers with their respective contents have to be pushed onto the baler and emptied in order to bring the desired volume of waste material into the baling chamber.
  • Such work processes are time-consuming and therefore undesirable, particularly with regard to reducing personnel costs, or such activities by operating personnel should be carried out in as time-saving a manner as possible.
  • the baling chamber has to be permanently closed after filling with waste material, there are undesirable work breaks for the respective operating personnel, because the operating personnel usually waits until the pressing process is completed in order to then couple a container with waste material to the baling press again.
  • the EP 2 537 668 B1 to remove a lifting and tipping unit, which is arranged on a narrow side of the baler housing for receiving a container or the like.
  • the lifting and tipping unit has a U-shaped mounting bracket, into which the respective container can be inserted for coupling to the lifting and tipping unit.
  • the lifting and tipping unit then lifts the container about a pivot axis in the direction of the filling opening, so that the waste material collected loosely in the container falls through the filling opening into the baling chamber of the baler housing due to the prevailing gravity.
  • the container or a collection truck is to be pushed into the U-shaped bracket of the lifting and tipping unit in the side area of the baling press housing and pulled out in the opposite direction.
  • the assembly or its orientation specifies the insertion and removal direction of the respective container. Should further stocks be parked in the area of the baler housing, access to the brackets of the lifting and tipping unit aligned in this way could be blocked or blocked, so that the containers can only be pushed into the bracket of the lifting and tipping unit after this area has been cleared.
  • the lifting and tipping unit must be moved through an angle of at least 120° around the axis of oscillation, since the container must first be transferred from the coupling position with the lifting and tipping unit to an outfeed position. To do this, the container must be raised above the baler housing and at the same time pivoted in such a way that the open end face of the container is aligned in the direction of the filling opening or in the direction of the direction of gravity.
  • balers are also made EP 3 199 331 A1 known. It describes how the compacted waste material is strapped with a wire loop, resulting in a compressed bale.
  • the wire loop namely runs parallel to the pressing direction, as a result of which the compacted waste material, after the bale has been strapped with at least one wire loop, is prevented from being able to fall apart when the bale escapes from the pressing chamber of the baling press to the outside.
  • the wire loop serves as a kind of packaging for the compacted waste material, so that the three-dimensional inner contour of the press room defines the outer contour of the strapped bale. Due to the compaction force prevailing between the compressed waste materials, they exert an inward-outward pressure on the respective wire loops, which oppose such an action of force and are consequently permanently under tension.
  • the wire loop inserted into the press chamber releases it in the entry area of the press ram and also rests completely against the three inner walls of the press chamber in order to ensure that the waste material pressed into the press chamber is completely surrounded by the wire loop.
  • the side wall opposite the ram and designed as a door initially serves as an opposite view for the pressing force applied by the ram and acting on the waste material. Therefore, if parts of the wire loop run inside the press chamber, the waste material would be pressed between the wire loop and the counter stop, for example, and this waste material could not be encompassed or encompassed by the wire loop.
  • the positioning processes of the wire loop within the baling chamber delay the movement of the baler, because every time a Once the strapped bale has been transported out of the baling chamber, a wire loop must be positioned in the baling chamber by machine or manually before the next baling process. This delays the pressing process.
  • the filling processes for the waste material can only be started when the wire loop in the pressing chamber is aligned according to the specifications.
  • the tying device has two drive units that are operated or arranged mechanically and spatially separately from one another, that the wire is pushed by the first drive unit through a guide channel worked into the side wall and through a guide channel worked into the ram, that the second drive unit pushes a second wire is pulled to the end position of the first wire and runs adjacent to it, that the two free ends of the wires are connected to one another by means of a knot by the tying device to form an open wire loop, that inside the pressing chamber there is at least one mint holder receiving the wire loop is provided in such a way that the wire loop running inside the pressing chamber is moved in the direction of a side wall designed as a door opposite the pressing ram, and the wire loop runs parallel to the side walls, that after the end of the compression process, the first free end of the open wire loop is guided through the press ram to the second free end of the open wire loop by means of the first drive unit, and that the two free ends of the open wire loop are connected by means of a knot and from the respective roll of
  • the filling of the baling chamber with waste material and the alignment of the wire loop inside the baling chamber can therefore take place at the same time, which means that the working frequency of the baling press can be clocked faster.
  • the wire loop is tied together, the wire for the next pressing process is already inserted into the pressing chamber in order to form the next wire loop.
  • the work steps for strapping the compacted bale can be combined to save time, because on the one hand the wire loop inserted into the baling chamber is closed by means of the chain link and knotted and cut off in the twisting and cutting device and on the other hand a new wire can be fed through the side walls of the bale Baler housing are pushed to form the wire loop for the subsequent pressing process.
  • the wire loop must first be positioned on the counter-stop or the door.
  • two pivoting arms are provided, which are pivoted inside the baler housing, the respective free end of which receives the wire loop in the upper and lower section and the pivoting arms are rotated by approx door is shifted.
  • the wire loop then runs along the inner walls of the press chamber, which means that the waste material and the press ram can move freely inside the press chamber. As soon as the wire loop is positioned inside the baling chamber, the baling process can begin with the filling of waste material into the baling chamber.
  • a baling press 1 is shown by which a large number of loose waste material 2, for example cardboard, paper, plastic bags, wooden crates or the like, which are removed from food shops as packaging before the food is sold, into a bale 40 strapped with a wire loop 39 Accordingly, the loose waste material 2 is compressed by the baling press 1, so that air pockets in the interstices of the waste material 2 or between them are pressed out during the pressing process. Waste material 2 compressed in this way can namely be stored and transported more optimally, since this volume is considerably reduced.
  • loose waste material 2 for example cardboard, paper, plastic bags, wooden crates or the like
  • the baling press 1 For compacting the waste material 2, the baling press 1 consists of a baling press housing 3 with six mutually perpendicular side walls 4, 5, 6, 7, 8 and 9. The lower horizontal side wall 9 is placed on a base 10. Accordingly, the six side walls 4 , 5 , 6 , 7 , 8 , 9 enclose a cuboid pressing chamber 14 . At least one press ram 11 is supported on one of the side walls 7 on the outside or inside, which plunger dips completely or at least for the most part into the press chamber 14 and exerts a compacting force on the waste material 2 filled in it. The press ram 11 is therefore axially movable and its direction of movement is identified as the pressing direction with the reference number 12 . The baling press 1 accordingly has a horizontal pressing direction 12 .
  • a filling opening 13 is first worked into the side wall 4 and can be closed by means of a pressing flap 45 .
  • the compression flap 45 is fastened to the outside of the side wall 4 via a pressure piston 46, so that the compression plate 45 already exerts a pre-insurance force on the waste material 2 introduced into the compression chamber 14, in particular if the waste material 2 is jammed in the area of the filling opening 13 .
  • the pressing chamber 14 When the pressing flap 45 is closed, the pressing chamber 14 is completely encapsulated and essentially has a cuboid inner contour.
  • the pressing ram 11 is activated so that the waste material 2 filled into the pressing chamber 14 is initially pressed in the direction of the side wall 8 designed as a door.
  • the closed one Door 8 therefore forms a counter stop for the pressing force of the ram 11; consequently, the waste material 2 is compacted or compressed between the side wall 8 and the ram 11 .
  • the ram or rams 11 can be attached completely inside the baler housing 3 or partially on the outside.
  • a lifting and tilting unit 17 is provided which is rotatably articulated on the end face of the baler housing 3 .
  • the carriage 16 can be coupled in a known manner to the lifting and tipping unit 17 and is then lifted and pivoted about an axis of rotation running perpendicularly to the pressing direction 12, as a result of which the open end face of the carriage 16 is aligned in the direction of the filling opening 13 and this in the carriage 16 Due to the prevailing gravity, the waste material 2 that is filled in falls into the pressing chamber 14 through the filling opening 13.
  • a wire roll 20 is first provided on the outside of the side wall 4 and a wire roll 19 is provided on the outside of the side wall 9 . Both wire rolls 19, 20 are therefore spatially separated from one another and are actuated mechanically differently. Both wire rolls 19, 20 provide a first and second wire 22, 23, through which the wire loop 39 is formed as described in more detail below.
  • a binding device 21 is available, to which two drive units 24, 25 are initially assigned.
  • the first wire 24 is taken up by the wire roll 19 by means of a link chain 27 as part of the first drive unit 24 and is threaded through a guide groove or guide channel 30 incorporated into the side wall 9 .
  • the link chain 27 accordingly pushes the wire 22 from the wire roll 19 through the guide channel 30 of the side wall 9.
  • the link chain 27 is in a guide tube 26 movably mounted; the contour or course of the guide tube 26 accordingly specifies the direction of movement of the link chain 27 .

  • a twisting and cutting device 38 is provided on the outside of the side wall 4, which in figure 2 is shown.
  • the first wire 22 is first threaded through the link chain 27 and connected there in a known manner to the second wire 23, which has been unwound from the second wire roll 20, by means of a knot 31, as a result of which an open wire loop 32 is formed , which is connected to both wire rolls 19 and 20.
  • Pressure pistons 46 are provided in the twisting and cutting device 38, through which the linear movements can be exerted on rollers or knives 44 in order to move or cut the wires 22, 23.
  • knots 31 or 35 are formed, through which the wire loop 32 is formed, namely when the two wires 22, 23 are connected to one another, and on the other hand the free ends of the wire loop 32 can be connected by means of the knot 35 and thus the wire loop 32 can be closed.
  • the motor 28 drives the link chain 27 in the opposite direction, so that it is pushed out of the guide channel 29 of the ram 11 or the guide channel 30 of the side walls 4 and 9 . Since the link chain 27 is still connected to the first wire 22, this runs inside the pressing chamber 14.
  • the guide channel 29 of the press ram 11 is open in the direction of the side wall 8 serving as a door, so that when the press ram 11 is pulled back the first wire 22 of the wire loop 32 emerges from the ram 11.
