Definitions

  • the invention relates to a baler for compacting loose waste material into a bale strapped with at least one wire loop according to the preamble of claim 1.
  • baling presses are well known.
  • a baling press with a vertically movable press ram is known, through which such waste material is compacted and pressed into a bale strapped with a wire loop.
  • the press ram therefore moves in a vertical direction within the pressing space and acts on the waste material filled into the pressing space from the outside, until the waste material is pressed into the desired bale size.
  • the problem with all baling presses is to transfer the waste material into the pressing room as quickly and easily as possible.
  • the waste material to be pressed which occurs in grocery stores in the form of boxes, packaging paper or foil, is first collected in mobile containers, carts or the like.
  • the container volume is filled with the waste material to be pressed, the respective operating personnel moves the container to the baler.
  • the container must be connected to a lifting and tilting device, for example from the EP 20 175 714.3 has become known.
  • the lifting and tilting device means that the container or waste container is lifted off the ground and moved in the direction of a filling opening opening into the pressing chamber and pivoted about the horizontal axis.
  • the open end face of the container first reaches the filling opening and points towards the ground, whereby the prevailing gravity acts on the waste material so that it falls out of the container through the entry opening into the pressing room.
  • 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 As soon as a certain amount of volume has been filled into the pressing space, the press ram must be activated and exerts a pressing force on the filled waste material, whereby it is compacted and pressed into the desired size of the bale when the specified volume amount is reached. Often several containers with their respective contents have to be pushed onto the baler and emptied in order to introduce the desired volume of waste material into the baling room. 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 as time-saving as possible. However, since the pressing room has to be permanently closed after filling with waste material, undesirable work breaks arise for the respective operating personnel, because the operating personnel usually wait until the pressing process is completed in order to then re-coup a container with waste material to the baler.
  • the EP 2 537 668 B1 to remove a lifting-tilting unit, which is arranged on a narrow side of the baler housing to accommodate a container or the like.
  • the lifting-tilting unit has a U-shaped receiving bracket into which the respective container is to be inserted for coupling to the lifting-tilting unit.
  • the lifting-tilting 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 pressing space of the baler housing due to the prevailing gravity.
  • the container or a collection truck must be inserted into the U-shaped bracket of the lifting and tilting unit in the side area of the baler housing and pulled out in the opposite direction.
  • the assembly or its orientation dictates the insertion and exit direction of the respective container. If additional stocks are stored in the area of the baler housing, access to the brackets of the lifting-tilting unit aligned in this way could be blocked or blocked, so that the containers can only be pushed into the bracket of the lifting-tilting unit after this area has been cleared.
  • the lifting-tilting unit must be moved by an angle of at least 120° around the oscillation axis, since the container must first be transferred from the coupling position with the lifting-tilting unit into an execution 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 gravity.
  • balers are also made EP 3 199 331 A1 known. It describes how the compacted waste material is strapped using a wire loop, so that a compressed bale is created.
  • the wire loop runs parallel to the pressing direction, which prevents the compacted waste material from falling apart after the bale has been strapped with at least one wire loop when the bale is released from the pressing space of the baler into the open air.
  • the wire loop therefore serves as a kind of packaging for the compacted waste material, so that the three-dimensional inner contour of the Press room specifies the outer contour of the strapped bale. Due to the compaction force prevailing between the compressed waste materials, they exert pressure from the inside out on the respective wire loops, which oppose such a force and are therefore permanently under tension.
  • the wire loop inserted into the press chamber releases it in the entry area of the press ram and, on the other hand, lies 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 press ram and designed as a door initially serves as a counter view for the pressing force applied by the press ram and acting on the waste material. Therefore, if parts of the wire loop run within the press space, then the waste material would be pressed, for example, between the wire loop and the counter-stop and this waste material could not be included or encompassed by the wire loop.
  • the positioning processes of the wire loop within the baling space delay the movement of the baler, because every time a Once the fully strapped bale has been transported from the pressing room, a wire loop must be positioned in the pressing room by machine or manually before the next pressing process. This delays the pressing process.
  • the filling processes for the waste material can only be started when the wire loop in the pressing room is aligned according to the specifications.
  • 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 baler can be clocked more quickly.
  • the wire loop is tied together, the wire for the the next pressing process is introduced into the pressing room to form the next wire loop.
  • the work steps for strapping the compacted bale can be combined in a time-saving manner, because on the one hand the wire loop introduced into the pressing room 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 inserted through the side walls of the bale at the same time Baler housing can be pushed to form the wire loop for the subsequent pressing process.
  • the wire loop is initially positioned on the counter-stop or the door.
  • the press ram or an ejector piston mounted axially movably on it is used to hold the wire loop, whereby the wire loop, which is open on one side, is aligned in the pressing space when the strapped bale is pushed out and consequently, after the press ram has been retracted into its starting position, immediately with the pressing process can be started by filling in loose waste material.
  • the two wires forming the wire loop can be introduced into the pressing chamber both manually and mechanically and connected to one another by a knot. It is only necessary to pull one of the two wires to the other wire mechanically or manually through the pressing chamber and/or the pressing ram and to knot the two free ends of the wires together. This measure initially creates a wire loop that is open on one side, which is moved by the press ram or its ejection piston in the direction of the door and the wires wound on the wire rolls are pulled off or extended.
  • FIG 1 a baling press 1 is shown, through which a large number of loose waste material 2, for example cardboard boxes, paper, plastic bags, wooden boxes or the like, which are removed from grocery stores as packaging before the food is sold, into a bale 40 strapped with a wire loop 39
  • the loose waste material 2 is therefore compressed by the baler 1, so that air pockets are squeezed out in the spaces between the waste material 2 or between them during the pressing process. Waste material 2 compressed in this way can be stored and transported more optimally since this volume is significantly reduced.
  • the baler 1 To compress the waste material 2, the baler 1 consists of a baler 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. The six side walls 5, 6, 7, 8, 9 therefore enclose a cuboid pressing chamber 14. On one of the side walls 7, at least one press ram 11 is supported on the outside or inside, which is completely or at least largely immersed in the press space 14 and exerts a compacting force on the waste material 2 filled therein. The press stamp 11 is therefore axially movable and its direction of movement is identified as the pressing direction with the reference number 12. The baler 1 therefore has a horizontal pressing direction 12.
  • a filling opening 13 is first incorporated into the side wall 4, which can be closed by means of a pressing flap 45.
  • the press flap 45 is attached to the outside of the side wall 4 via a pressure piston 46, so that the press plate 45 already exerts a pre-insurance force on the waste material 2 filled into the press chamber 14, especially if waste material 2 should be clamped in the area of the filling opening 13 .
  • the press space 14 is completely encapsulated and essentially has a cuboid inner contour.
  • the press ram 11 is activated so that the waste material 2 filled into the press chamber 14 is initially pressed in the direction of the side wall 8 designed as a door.
  • the closed door 8 therefore forms a counter-stop for the pressing force of the press ram 11; Consequently, the waste material 2 is compacted or compressed between the side wall 8 and the press ram 11.
  • the press ram or presses 11 can be mounted completely inside the baler housing 3 or partially on the outside.
  • a lifting-tilting unit 17 which is rotatably articulated on the front side of the baler housing 3 is provided.
  • the carriage 16 can be coupled in a known manner to the lifting-tilting unit 17 and is then lifted and pivoted about an axis of rotation running perpendicular 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 into the carriage 16 Filled waste material 2 falls into the pressing chamber 14 through the filling opening 13 due to the prevailing gravity.
  • a wire roll 20 is initially 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 mechanically operated differently. Both wire rolls 19, 20 provide a first and second wire 22, 23, through which the wire loop 39 is created, as described in more detail below.
  • the movement or unwinding of the wires 22, 23 is carried out manually or mechanically.
  • the first wire 22 is picked up by the wire roll 19 by means of a conveyor device 21 and threaded through a guide groove or guide channel 30 incorporated into the side wall 9.
  • the conveyor device 21 accordingly pulls the wire 22 from the wire roll 19 through the guide channel 30 of the side wall 9 and brings the wire 22 to the outside of the side wall 4, i.e. into the area of the second wire 23.
  • a guide channel 30 is also incorporated into the side wall 4, through which the wire 22 is pushed.
  • a twisting and cutting device (not shown) can be provided on the outside of the side wall 4.
  • the first wire 22 is first threaded manually and connected there in a known manner to the second wire 23, which is unrolled from the second wire roll 20, by means of a knot 31, whereby a wire loop 32 that is open on one side is created, which with two wire rolls 19 and 20 are connected.
  • the wires 22, 23 can be cut manually.
  • the pressing process starts by activating the press ram 11 and the loose waste material 2 is removed according to Figure 4 compacted into the bale 40.
  • the wires 22, 23 can either be unwound manually from the respective wire rolls 19, 20 and inserted into the pressing chamber 14 and knotted together or - as in the Figures 1 to 4
  • a conveyor device 21 which is moved back and forth by means of a motor 28.
  • the conveying device 21 consists of a type of needle with a gripping mechanism, through which the wire 22 is picked up outside the side wall 9 and is pulled through the pressing space 14 parallel to the press ram 11 in the direction of the side wall 4 and through it to the outside.
  • the press stamp 11 is shown in an enlarged view.
  • an ejection piston 36 is supported on this in an axially movable manner. Since the ejection piston 36 is arranged telescopically on the press ram 11, an extremely space-saving one is created Arrangement with simultaneous enlargement or extension of the ejection path for the strapped bale 40.
  • a guide channel 37 is provided for each of the wire loops 32 both in the press ram 11 and in the ejection piston 36, which has a contour that is as homogeneous or rounded as possible.
  • Press ram 11 and ejection piston 36 shown can accommodate a total of four wire loops 32 running parallel to one another and move them in such a way that when positioning the respective wire loop 32, bending or cutting off due to sharp edges on the ejection piston 36 are avoided.
  • magnets 41 are provided in this area. This is particularly out Figure 3 refer to.
  • the magnets 41 attract the wire loops 32 made of metal so that they remain in the aligned position during the filling and pressing process.
