Definitions

  • the present invention relates to a channel baling press with the features of the preamble of claim 1.
  • Baling presses are generally used for compacting loose materials to be shaped into an advantageous shape for transportation and storage purposes.
  • Various types of presses are known for the production of cuboid bales, namely box presses (English: two ram baler), in which a first press ram compresses the material into a press box and a second ram causes the pressed bale to be ejected into a binding device .
  • the other type is that of a channel baler (English: single ram baler), in which a press ram presses the material to be pressed from a feed area into a bale channel. In this bale channel, the material to be pressed is compacted against bales that are already there.
  • bale channel The friction of the existing bales in the bale channel creates the counter pressure required for compaction.
  • the bales are delivered in the same direction in which the baling process takes place.
  • the bale is tied when a predetermined length of the bale has been reached in the pressing direction.
  • the material or compacted material to be compacted can vary greatly, ranging from lightweight, easy-to-compact materials such as recycled plastic waste and cardboard to difficult-to-compact materials such as old tires or scrap metal. There are the The degree of compaction and the tendency to re-expand the material vary greatly.
  • the positioning of the compacted material in a formed bale can also vary. Materials that interlock with each other during the pressing process can form a very well-defined bale. Materials with round cross-sections that are difficult to compact tend to form unstable bales. For the latter reason, a so-called vertical tie-off is advantageous in channel baling presses, in which a number of parallel ties are created across the front end face in the pressing direction, the upper and lower long sides and the rear end face. This binding prevents material from falling out on the lower long side when the bale is lifted and moved.
  • the terms "vertical” and “horizontal” in this context are not understood in a narrow sense, for example to mean a direction parallel to the gravity vector or orthogonal to the gravity vector. Rather, the directions referred to as vertical and horizontal are essentially to be understood in this sense, with the horizontal direction approximately corresponding to the course of the pressing direction, i.e. depending on the design and installation of the channel baling press also an angle of a few degrees, for example 2° to 10° inclination angle the horizontal can have.
  • the vertical direction is also to be understood as having a tolerance range of a few degrees, for example 2° to 10° angle of inclination relative to the vertical.
  • a vertical binding creates a loop of bandaging material around the bale, which runs in a vertical plane, the vertical plane being essentially spanned by the vertical direction and the pressing direction.
  • the horizontal binding is accordingly created in a horizontal plane that is spanned by the pressing direction and a horizontal oriented transversely to the pressing direction.
  • both bandaging devices each comprising a connecting device for connecting ends of the bandaging material, in particular in the form of twisting devices
  • the first bandaging device has a first, vertically oriented cross-connector for the bandaging material, in particular in the form of a pulling device
  • the second bandaging device has a second, horizontally oriented transverse conveyor for bandaging material, also preferably in the form of a pulling device
  • the second bandaging device has automatic holding means and separating means that work as a function of a control for holding and separating the bandaging material, this can Bandaging material of the horizontal binding is separated depending on a control, kept ready and reconnected if necessary.
  • the process can be done automatically and therefore quickly and safely.
  • the cross connectors are preferably designed to have multiple tracks, in particular with three to five tracks.
  • the bandaging material can be separated in spatial proximity to the holding means and kept there ready for the next horizontal strapping.
  • the resulting amount of bandaging material to be discarded is thereby reduced.
  • Guide means in particular deflection rollers, are provided on the same side of the bale channel in order to guide the respective strand of bandaging material so that it can be grasped by the pulling device and pulled transversely to the pressing direction along the back of the finished bale across the press channel.
  • the guide means can be moved essentially parallel to the pressing direction, i.e. parallel or at an acute angle.
  • the guide means can also be arranged to be pivotable about an approximately vertical axis, so that the guide means can be moved between a first and a second position.
  • the first and second positions are at a distance from one another in the conveying direction. It is irrelevant whether the positions are at a distance from one another across the conveying direction.
  • the guide means can influence the strand guidance, for example in such a way that the strand comes into the effective area of the holding and separating means or is guided out of it.
  • the automatic holding means and/or the automatic separating means can be moved substantially parallel to the pressing direction, i.e. parallel or at an acute angle. Then the strand of the bandaging material held in the holding means and/or the intended separation point in the area of the bandaging device can, for example, be of one Rest position can be moved into an operating position and back, for example in order to specifically feed the bandaging material to the pulling device.
  • a particularly effective holding means which also withstands high tensile forces acting on the bandaging material, has a separate, in particular concave, abutment for each track and a matching, in particular wedge-shaped, clamping member. These are preferably hydraulically actuated.
  • a holding means is provided for each track of the bandaging material and all holding means can be controlled and driven together, in particular synchronously.
  • the channel baling press has a separate separating means for shearing off the bandaging material for each track, and these can also preferably be controlled and driven together, in particular synchronously. This makes the separation process particularly quick and reliable.
  • the holding means does not work against the abutment, but rather deforms the bandaging material by pushing a region of the bandaging material into the abutment without strictly clamping it between the clamping member and the abutment. In bandaging material such as steel wire, this deformation creates enough friction to generate sufficient holding force.
  • the holding means and the separating means are driven by a common, in particular hydraulic, actuator. This simplifies control, especially when all holding means and all separating means are driven together.
  • the bandaging material is, for example, in the form of a steel wire, which is kept in a left and a right strand for each track in relation to the pressing direction and is drawn off from a supply spool for this purpose.
  • a drilling device is provided on the side of the channel bale press opposite the holding means, in particular a drilling device with two driven drilling grippers or drilling hooks, namely one closer to the press ram in the pressing direction upstream drill hook and a drill hook closer to the bale exit and downstream in the pressing direction for each track of the horizontal bandaging device.
  • the drill hooks of the second, horizontal bandaging device can be driven separately, preferably all upstream drill hooks together and/or synchronously, and all downstream drill hooks also together and/or synchronously.
  • a second separating device can be arranged between an upstream twist hook and a downstream twist hook.
  • the Figure 1 shows part of a channel baling press in a top view.
  • the illustration is a schematic sectional view in a longitudinal section parallel to a pressing direction P.
  • the drawing plane is a horizontal plane of the device, which is spanned by the pressing direction P and a transverse direction Q oriented at right angles to the pressing direction P.
  • the channel baling press has an input area 1, not shown, into which material to be pressed is to be entered loosely.
  • a Hydraulic unit 2 is provided to move a press ram 3 from the input area 1 into a bale channel 4 and thereby compress the material to be pressed there. Several working strokes of the press ram 3 produce a bale 5.
  • a bandaging device Seen in the pressing direction P, a bandaging device with several components is provided in a downstream area of the bale channel 4, approximately where the working stroke of the hydraulic unit 2 ends, which are essentially known from the prior art.
  • the bandaging device specifically comprises a left supply spool 10 in this illustration and a right supply spool 11.
  • the two supply spools 10 and 11 hold a bandaging material in the form of a quasi-endless steel wire for strapping the bales produced.
  • a left strand 12 of the bandaging material runs from the supply spool 10 through a left guide means 13, which is formed by two deflection rollers and guides the wire to a wire entry, not shown, in the bale channel 4.
  • a right strand 14 runs from the supply spool 11 to a right guide means 15, which also has two deflection rollers and leads the wire to a right wire entry of the bale channel.
  • a connecting device 17 is arranged in the area of the guide means 13 and 15, which in this case is designed as a twisting device due to the use of steel wire. This device is described in more detail below. What is important here is that the connecting device 17 includes a first twist hook 18 and a second twist hook 19, each of which can be driven separately.
  • the first twist hook 18 is driven by a first drive 20 to rotate about a horizontal axis of rotation which is oriented parallel to the transverse direction Q.
  • the second drill hook 19 is driven by a second drive 21 about a corresponding parallel axis of rotation. Both drives 20, 21 are controlled by a control 22, which is only shown schematically.
  • the connecting device 17 further comprises a drawing needle 23, which is operated by a drive 24 in parallel to the control 20 Transverse direction Q can be moved.
  • the design of the drawing needle 23 is known from the prior art.
  • the guide means 15 is arranged on an actuator 25, which is set up to move the guide means 15 parallel to the pressing direction P not far from the control 20.
  • the actuator 25 can in particular be driven hydraulically.
  • the right strand 14 of the bandaging material runs between the guide means 15 and the bale channel 4 via a combined holding and separating means 26, which is not shown in more detail here.
  • the combined holding and separating means 26 is also hydraulically actuated and has a concave, fixed abutment and a movable, matching wedge-shaped clamping element, between which the bandaging material can be clamped and held.
  • a release agent in the form of a shearing device is also provided.
  • a first bale 5 is completely produced and compacted.
  • the pressing pressure with which the bale 5 was compacted is maintained by the hydraulic unit and the press ram 3 in order to prevent the bale 5 from expanding back as long as it is not yet strapped or bandaged.
  • the bale 5 automatically took bandaging material with it, namely removed from the left supply spool 3 and the right supply spool 11.
  • the strand 12 rests on the left side of the bale 5 in the pressing direction P.
  • the strand 14 rests on the side leading in the pressing direction P and on the right side of the bale 5.
  • a twist 28 which was previously generated by the connecting device 17, the two strands 12 and 14 are connected to one another in a tension-resistant manner.
  • the Figure 2 shows that based on the operating state in Figure 1 the drawing needle 23 and in the drive 24 are moved in the transverse direction into the bale channel 4, more precisely into a horizontal groove 29 of the press ram 3.
  • the Figure 3 shows how the drawing needle 23 has moved to its right end position.
  • One end 30 of the drawing needle 23 has been moved between the right guide means 15 and the combined holding and separating means 26 and under the strand 14 located there into an extreme right position (relative to the pressing direction P).
  • the end 30 of the drawing needle 23 has a head, which is not shown in detail here.
  • the head essentially comprises a catching element in the manner of a barb and a roller over which the strand 14 can roll.
  • the channel baling press illustrated here is intended to provide the option of choosing whether the bale produced should be tied horizontally or not, and to automatically carry out the necessary steps for this. It should also be mentioned that a conventional vertical tying, which is not shown in the figures, is present in this channel baling press and that it is always active.
  • the bales produced are either strapped vertically and horizontally, as with the bale 5 shown here, or only strapped vertically when the horizontal strapping is switched off.
  • the Figure 6 now shows the process step that is carried out if the next, not yet produced bale is to be produced without horizontal bandaging.
  • this step only the downstream twisting hook 19 has been driven and has grasped and twisted the strands 12 and 14 extending from the bale downstream of the pulling needle 23, so that the bale 5 is completely wrapped around with a second twist 28 'and secured against re-expansion.
  • a separating device assigned to the connecting device 17 then severed the two strands 12 and 14, so that the bale 5 is free of the virtually endless strands 12 and 14 and can be dispensed.
  • the actuator 25 is controlled in order to move the guide means 15 parallel to the pressing direction P into a downstream end position. This movement causes the free end of the right strand 14 to be pulled out of the upstream twist hook 18. It lies loosely in the groove 29 of the press ram 3.
  • the strand 14 is also brought closer to the combined holding and separating means 26.
  • the holding and separating means 26 is now closed by vertically advancing the clamping element, not shown, whereby the strand 14 is clamped and held.
  • the free end of the strand 14 lying in the groove 29 is separated from the associated separating device close to the holding means 26 and is present as a section 31. This section 31 is discarded in the further process in which it is processed in the subsequently produced bale.
  • the Figure 9 shows the tying device of the channel baling press in the same condition as that Figure 8 .
  • another bale 35 has been produced in the bale channel 4. Since the left strand 12 and the right strand 14 are currently not connected to each other, none of the strands 12, 14 were taken along by the bale 35.
  • the bale 35 is not strapped horizontally, but only vertically.
  • the discarded section 31 lies at the front in front of the bale 35 and is strapped together with the bale 35 by the vertical bandaging.
  • the channel baling press is now prepared for the horizontal strapping of the next bale.
  • the Figure 12 shows how the drawing needle 23 grasps the right strand 14 with its head 30 and takes it into the groove 29 in the backward movement.
  • the strand 14 is pulled off the right supply spool 11.
  • the free end remains fixed in the combined holding and separating means 26.
  • Figure 14 shows that this created a twist 36, which firmly connects the left strand 12 and the right strand 14 train.
  • the piece of the right strand 14 located between the pulling needle 23 and the combined holding and separating means 26 is then separated from the separating device of the connecting device 17, the clamping device is released and the separated wire is now present as a section 37 in the groove 29. This section 37 is again rejected.
  • the Figure 15 finally shows how a third bale 45 was produced, through which the non-horizontally strapped bale 35 was transported further in the pressing direction in the bale channel 4.
  • the third bale 45 in the sequence shown has in turn taken along the two strands 12 and 14 connected to one another in the twist 36.
  • the channel baler is now in the condition of Figure 1 .
  • the bale can now be strapped completely horizontally.
  • the control 22 can also make this decision itself, for example by comparing predetermined parameters of the bales 5, 35 and 45 produced depending on target values.
  • the pulling needle starts from Figure 15 the right strand 14 and the left strand 12 between the two twist hooks 18 and 19 (as in Fig. 2 to 5 shown). Then the twist hooks 18 and 19 are controlled simultaneously, so that two twists are created, between which the strands 12 and 14 are then separated. Then one twist remains with the bale 45 and closes its horizontal bandaging, while the next twist is taken from the leading side of the bale that is still to be produced and becomes the starting point for the next horizontal strapping.
  • bale following the bale 45 is not to be strapped, then the procedural steps are as described above using the Figures 2 to 15 carried out as described.
