Definitions

  • the invention relates to a baling press for compacting loose waste material, which is set up on a base, according to the preamble of patent claim 1.
  • baling presses have been used for decades in grocery stores, for example, in order to compact packaging materials for food, since the storage and transport of the packaging materials that are no longer required is otherwise extremely voluminous. For storage as well as for transport purposes, however, it is absolutely necessary to compact this packaging material into a bale with as few air pockets as possible, which is usually strapped by at least one wire loop, in order to prevent the waste material from falling apart after the pressing process and removal of the bale strapped in this way impede.
  • These baling presses are known as so-called counter-stop baling presses in a wide variety of structural configurations, namely as so-called horizontal, vertical or inclined baling presses.
  • the orientation of the baling press refers to the movement of the press ram, which is mounted inside the baling press housing so that it can move axially, and which accordingly runs either horizontally, vertically or at an angle.
  • a baler in horizontal design can be removed from the EP 2 537 668 B1 .
  • a boxing carriage filled with the loose waste material to the baler, this to a provided on the outside of the baler housing and pivotable coupled lifting / tipping device, whereby the boxing carriage is raised with the waste material from the ground and moved about a pivot axis in the direction of a machined in one of the side walls of the baler housing filling opening. Due to the pivoting movement of the boxing carriage, which is generated by the corresponding arrangement and structural design of the lifting/tipping device, the open side of the boxing carriage is aligned with the filling opening and points in the direction of the ground.
  • the waste material collected in the boxing carriage then falls through the filling opening into the baling chamber of the baling press.
  • the pressing process begins with the press ram, which accordingly exerts a pressing force on the waste material, so that the waste material is compacted into a bale.
  • the loose waste material is compacted into the bale and strapped with a wire loop, the bale can be pulled out of the baling chamber or pushed out by ejector pistons known in the art.
  • a disadvantage of the previously known baling presses has been found to be that the process of filling the loose waste material into the baling chamber of the baling press has to take place at a different time than the actual pressing process, because the pressing chamber is completely closed during the pressing process, so that the filling opening of a filling of the pressing chamber with waste material is in the way.
  • the boxing trolley filled with waste material must be lifted off the ground and moved in the direction of the filling opening.
  • additional structural measures such as the provision of a correspondingly suitable lifting/tilting device that accommodates the boxing carriage and its corresponding actuation for lifting and pivoting.
  • the hopper in the baling presses that have become known is located at a great distance from the ground. This is due to the fact that, particularly in the case of vertically aligned balers Drive for the respective ram is provided above the press room. Immediately adjacent to the drive is the filling opening in one of the side walls, and this is followed by the pressing chamber inside the baling press housing. Even with horizontally operated baling presses, the filling opening is located above the pressing chamber so that the waste material can be filled directly into it.
  • An energetically particularly favorable filling of the pressing chamber takes place in that a conveyor belt is provided in front of the conveyor device, through which the waste material is transported to the conveyor device and then from it into the guide channel.
  • the conveyor belt is set up on the ground so that the loose waste material requires little energy to move it from the ground to the filling opening in the side wall.
  • a vertically operated baler 1 formed of a baler housing 3 is shown.
  • the press housing 3 consists of six side walls 4, 5, 6, 7, 8, 9, which are perpendicular to one another, so that the interior of the baler housing 3 consequently has a cuboid contour.
  • a filling opening 13 is provided in the side wall 4, which is aligned perpendicularly to a base 10.
  • the filling opening 13 is positioned in such a way that a pressing chamber 14 runs below it inside the baler housing 3 and above the filling opening 13 a drive 15 for the axial actuation of a press ram 11 can be installed.
  • the ram 11 can be moved like a stroke by the drive 15; the press ram 11 is mounted in the bale press housing 3 so that it can move axially.
  • Loose waste material 2 can be filled in through the filling opening 13 and, due to the prevailing force of gravity, falls into the pressing chamber 14 provided below the filling opening 13 .
  • the side wall 9 serves as a base and consequently as a counter-stop for the loose waste material 2, which is compacted between the side wall 9 and the ram 11.
  • the other side walls 4, 5, 6 and 7 act as a support for the loose waste material, so that after the end of the pressing process a cuboid bale is formed in the pressing chamber 14.
  • These are known vertically operated baling presses 1. It is easily conceivable to provide the pressing direction of the press ram 11 in a horizontal or inclined direction or to selectively press through the loose waste material from a press channel.
  • the filling chute 13 runs above the base 10 and the loose waste material 2 can thus be transported or moved to the filling opening 13 .
  • the loose waste material 2 which accumulates, for example, in grocery stores in the form of packaging of all kinds, is collected in a boxing trolley 29, which has an upwardly open side 29' through which the waste material 2 can be filled.
  • the boxing carriage 29 is filled with uncompacted loose waste material 2 , it is to be moved to the baling press 1 in order for the baling press 1 to compact the collected waste material 2 .
  • the pressing chamber 14 is usually filled by providing a lifting/tipping device 28 on one of the outsides of the baler housing 3, to which the respective boxing carriage 29 can be coupled. As soon as the boxing carriage 29 is locked with the lifting/tipping device 28, the boxing carriage 29 and consequently the waste material 2 can be raised and moved and pivoted in the direction of the filling opening 13, so that when the filling position is reached the loose waste material 2 can be removed from the boxing carriage 29 falls through the filling opening 13 into the pressing chamber 14.
  • the waste material 2 retains its original shape and size, so that the baling chamber 14 is already filled after just a few filling processes, and consequently the press ram 11 must be actuated in order to pre-compact the voluminous waste material 2 in order to be able to add further waste material 2 to form a correspondingly voluminous bale .
  • the guide channel 21 has a first open end 22 which is arranged in alignment with the filling opening 13 and opens into it.
  • the second open end 23 of the guide channel 21 faces the ground 10 .
  • a conveying device 24 in the form of a conveying shaft which is set in rotation in a controlled manner by a drive 25 .
  • a feed chute 27 is arranged in front of the conveyor device 24, on the outside of which the lifting/tipping device 28 is attached and by means of which the respective boxing carriage 29 is raised and pivoted in such a way that the loose waste material 2 is pushed out of the boxing carriage 29 falls into the hopper 27.
  • the cross section of the feed chute 17 can be reduced or enlarged so that the size or the Volume of the waste material 2 has to have a predetermined size or volume in order to get in the direction of the conveyor 24 at all.
  • the volume of the waste material 2 already present in the hopper 27 can be reduced by means of the pressure pistons 17 or the pressure plates 18 .
  • the waste material 2 reaches the lower area through the rotating conveying device 24, on which a plurality of conveying blades 26 are attached, which act directly on the waste material 2 and consequently convey it out of the hopper 27 into the guide channel 21 through the second open end 23 of the guide channel 21, i.e. in the area of the subsurface 10. Due to the permanently following waste material 2 and the rotation of the conveyor shaft 24, the following waste material 2 pushes the waste material 2 already present in the guide channel 21 against the direction of gravity to the filling opening 13.
  • a flap 16 is pivotally mounted, which is controlled by the drive 15 and transferred to the open or closed position.
  • the flap 16 is open and consequently the filling opening 13 is released, and during the pressing process by the press ram 11 the flap 16 is closed and the filling opening 13 is blocked.
  • the cross-sectional area of the guide channel 21 has a tapering contour, starting from the first open end 22 with a significantly larger cross-sectional area in the direction of the second open one End 23 with a much smaller sized cross-sectional area. Due to the rotation of the conveyor device 24 and the selected inner contour of the guide channel 21, a pre-compression of the waste material 2 present there takes place immediately after the conveyor device 24, so that the volume of the waste material 2 filled into the baling chamber 14 is significantly smaller than in previously known baling presses, since the Waste material 2 is already pre-compacted in the guide channel 21 and by the conveyor 24 .
  • the increasing inner cross-sectional area of the guide channel 21 allows the volume of the pre-compacted waste material 2 to expand, so that it can be transported in the most energy-saving manner possible and without jamming.
  • FIG 2 shows the control of the drives 12, 15 and 25 for the components controlling the filling and pressing process. This takes place via a schematically illustrated control device 35, which is connected to the drives 12, 15, 25 via electrical lines 36.
  • the respective operating states of the drives 12, 15, 25 and/or positions of the movable press ram 11 and the flaps 16 are via sensors recorded and therefore the pressing process is started or stopped or the filling process is regulated accordingly. Regardless of the pressing of the waste material 2, this can still be inserted through the hopper 27 into the guide channel 21, because even with a closed flap 16, both the hopper 27 and the guide channel 21 loose as well record pre-compacted waste material 2 in a certain volume range and already transport it in the direction of the filling opening 13 .
  • FIG 3a is an enlarged view of the conveyor 24 can be seen, which is formed from a conveyor shaft.
  • a plurality of conveying blades 26 are attached, formed or provided on the lateral surface 24' of the conveyor shaft 24, which protrude essentially radially from the lateral surface 24' and act directly on the loose waste material 2 in order to move it.
  • the conveyor device 24 is driven by the electric motor 25.
  • a filling of the baler housing 14 can be seen without a lifting/tipping device and, in addition, the waste material 2 should be conveyed from the subsoil 10 exclusively by the conveying device 24 through the guide channel 21 into the baling chamber 14.
  • a conveyor belt 31 is arranged on the base 10, by which the heaped waste material 2 is moved in the direction of the conveyor 24.
  • a knife shaft 32 can be provided between the conveyor device 24 and the conveyor belt 31, which is set in rotation. Accordingly, as soon as the loose waste material 2 reaches the cutter shaft 32 from the conveyor belt, the waste material 2 is cut up by the cutter shaft 32 and consequently comminuted. These already shredded parts of the waste material 2 are picked up by the conveyor 24 and pushed through the second open end 23 into the guide channel 21 . Contrary to the prevailing force of gravity, the conveying device 24 conveys the waste material 2 that has already been filled or pressed into the guide channel 21 by pushing further quantities of waste material 2 in the direction of the first open end 22 and consequently through the filling opening 13 into the baling chamber 14 of the baling press 1.
  • a ramp 33 is provided in front of the conveyor belt 31, over which the respective boxing carriage 29 can be driven manually or by means of independent drives, so that the boxing carriage 29 with the waste material 2 filled in it is positioned above the conveyor belt 31 is.
  • the bottom 30 of the boxing carriage 29 is movably held in the frame of the boxing carriage 29, so that the bottom 30 can either be closed or opened.
  • the waste material 2 falls through the released opening in the direction of the ramp 33, in which a passage opening 34 running flush with the conveyor belt 31 runs above it, due to the prevailing gravity. Consequently, the waste material 2 falls through the opening released from the floor 30 through the passage opening 34 incorporated in the ramp 33 onto the conveyor belt 31 and, due to the linear movement of the conveyor belt 31, first reaches the cutter shaft 32 and then the conveyor device 24.
