Definitions

  • the present invention relates to a baling press with a press housing surrounding a press chamber, a press plate which can be moved in the press housing and which can be driven by hydraulic cylinders.
  • the invention also relates to a method for operating the baler.
  • U.S. 2013/0270730 A1 there is known a compression molding apparatus for melting a resin material, in which fibers are supplied to the molten resin, and then resin and fibers are pressed into a mold.
  • the compression molding apparatus includes lower and upper molds and at least three compression hydraulic cylinders attached to the upper and lower molds. Position sensors are provided to detect the distance between the upper and lower moulds. And according to their information the Compression hydraulic cylinders can be controlled individually.
  • the compression molding device is neither intended nor suitable for compressing material in the form of balls.
  • U.S. 5,868,067 A a baler for compacting fibers and other compactable materials such as refuse is known.
  • the baler consists of a primary hydraulic cylinder and a faster-acting secondary hydraulic cylinder, both of which are attached to a press plate designed to compact the material.
  • the second compression means works faster than the first compression means and exerts a tamping movement on the material to be pressed, which has been pre-compacted by the first compression means.
  • Both compression means have a common hydraulic system and a solenoid valve. Hydraulic oil is supplied to the two hydraulic cylinders and the ramming strokes are activated by means of a control provided for this purpose.
  • the disadvantage of this system is that although two cylinder pairs with a total of four cylinders are provided, the two secondary cylinders only serve to increase the lifting speed in the unloaded state.
  • the material compression is carried out exclusively with the primary cylinders.
  • a device for compensating tilting moments on a ram of a press comprises at least one pair of identical hydraulic cylinders, the pistons of which are each connected to the ram.
  • the hydraulic cylinders are synchronous cylinders (also called synchronous cylinders), which have a piston rod on both sides of the piston surface.
  • the volume of the inflowing and outflowing hydraulic oil is therefore always the same.
  • the cylinder therefore moves in and out at the same speed.
  • the chamber of each hydraulic cylinder arranged above the piston is connected to the chamber of the respective other hydraulic cylinder of the pair arranged below the piston via a respective connecting line.
  • a baler with two double-acting hydraulic cylinders is known.
  • the hydraulic cylinders are connected to each other via a bridge construction and two pressure plates attached to it.
  • two electrical switches are provided which are activated by a pin whenever the bridge structure connecting the hydraulic cylinders is moved from its normally horizontal position position in an inclined position.
  • the disadvantage of the control is that the cylinders can only be controlled roughly and fine control is not possible.
  • a press for wool with a frame and a press plate that can be moved into a press chamber is known.
  • wool holding elements are provided in the form of pins engaging laterally in the pressed bale, which are inserted into the wool ball from the sides after compaction and before the pressing plate is moved upwards.
  • the pins that engage laterally in the pressing chamber thus serve as hold-down devices for the material to be compacted and prevent it from expanding when the pressing plate returns.
  • U.S. 3,851,577 A discloses a baling press for compressing waste, for example cardboard boxes, with a compression chamber and a hydraulic cylinder mounted on a compression plate above the compression chamber. To reduce the overall height of the baler for shipping, the cylinder can be lowered down into the housing. However, the conversion is time-consuming and expensive.
  • a further disadvantage of a system with a hydraulic cylinder arranged above the bale chamber is the high overall height associated therewith. Baling presses with such a structure are therefore unsuitable for rooms with a low overall height.
  • U1 is a baler for compacting loose material such as cardboard boxes known.
  • Such baling presses are used in supermarkets, among other things, to compress the cardboard boxes, cardboard and other wrappings of sales goods that are placed loosely on sales shelves or removed from them, in order to minimize the resulting volume of residues to be disposed of.
  • the pressed cardboard boxes or the like can also be strapped with wires or plastic straps directly in a press shaft of a press housing.
  • a press plate is moved downwards with two hydraulic cylinders arranged on top of the press shaft. This requires a large overall height of the baler.
  • the arrangement of the hydraulic cylinders above a press housing requires a large room height in order to be able to set up the baler in a building protected from the weather.
  • the document DE 10 2005 037 147 A1 shows a baler with a press housing, which surrounds a bale chamber, with a power drive consisting of four hydraulic cylinders, a press plate can be moved in the press chamber.
  • Two hydraulic cylinders each work together as a master-slave cylinder pair.
  • the hydraulic cylinders can also be arranged on the side of the press housing in order to reduce the overall height of the baling press.
  • the operation of a baler with master-slave hydraulic cylinders requires considerable technical effort, in particular special and therefore expensive hydraulic cylinders.
  • the U.S. 10,471,673 B2 discloses a baling press with a press shield that can be moved in a press housing and is driven by hydraulic cylinders.
  • the hydraulic cylinders arranged in the press housing act in groups on an additional intermediate plate and the press shield.
  • the DE 10 2005 037 147 A1 discloses a baling press according to the preamble of claim 1 with a press plate which can be moved in a press housing and which is driven by hydraulic cylinders.
  • the hydraulic cylinders are arranged in pairs on two opposite sides outside of a bale chamber (2).
  • the hydraulic cylinders are controlled according to the master-slave principle.
  • the DE 10 2013 014 discloses a baling press with a press shield that can be moved in a press housing and is driven by hydraulic cylinders. Three hydraulic cylinders are arranged linearly in a row. In this case, only one hydraulic cylinder can drive the pressing plate against a pressing direction.
  • the object of the present invention is therefore to specify a baling press that has a low overall height and a simplified structural design. Furthermore, a corresponding method for operating such a baling press is to be specified.
  • the core idea of the invention is that in a baling press which, as explained above, has a press housing with a pressing chamber, a pressing plate and hydraulic cylinders for driving it, a total of four hydraulic cylinders are provided are arranged in pairs on one side of the press plate, the hydraulic cylinders of each pair of cylinders being press pressure-dependent in each case selectively individually or jointly controllable by means of a control device.
  • a pressure cylinder is understood to mean a cylinder in which hydraulic oil is applied to the piston surface during the pressing process.
  • a pull cylinder is understood to mean a cylinder in which hydraulic oil is applied to the piston ring surface during the pressing process.
  • a baler with pull cylinders has the advantage that the hydraulic cylinders do not protrude beyond the bale chamber or the press plate.
  • the pull cylinder baler can therefore have a higher and therefore larger baling chamber than a pressure cylinder baler.
  • the baling press according to the invention with traction cylinders is therefore particularly well suited for rooms with a low overall height.
  • the hydraulic cylinders acting on the press shield are preferably designed in such a way that, when the press shield is moved to its uppermost position, they practically do not protrude upwards over the press shield.
  • the hydraulic cylinders are arranged in pairs on the left and right opposite one another on two sides of the usually rectangular press plate.
  • a lower transverse yoke is preferably provided, to which the cylinders are attached.
  • the control device is designed to apply hydraulic oil to the various hydraulic cylinders of the baling press in the desired manner, i.e. to lower the press plate to compress material to be pressed, such as cardboard boxes or the like, and to also raise the hydraulic cylinders in the opposite direction in a targeted manner of the press shield.
  • the control device is designed in such a way that either only one or both hydraulic cylinders of each cylinder pair, which are arranged adjacent on one side of the press plate, are controlled. This offers the advantage that when the baling chamber of the baling press is almost empty or only easy-to-compact material is filled in, only one hydraulic cylinder on each side of the pressing plate is activated.
  • the piston rod of the cylinder that is not activated in each case is taken along by the cylinder that is activated in each case next to it.
  • the two hydraulic cylinders arranged on one side of the press plate are mechanically coupled to one another, so that moving the piston rod of one controlled hydraulic cylinder up or down also moves the piston rod of the other cylinder.
  • the hydraulic control device is preferably an electronic unit, such as a PLC control.
  • a further advantage of the invention is that the lateral arrangement of the hydraulic cylinders means that the baling press can also be set up in rooms with low ceilings and can also be transported through low doors or gates.
  • the hydraulic cylinders can be activated in such a way that if initially only one cylinder is activated on each side, this occurs crosswise, for example the left rear and right front cylinders or alternatively the left front and right rear cylinders. In this way, a more even application of force to the press plate by the hydraulic cylinder can be achieved in order to prevent the press plate from tilting.
  • a hydraulic main switching valve and a hydraulic pressure switching valve are provided for the actuation of the hydraulic cylinders, which can be controlled by the hydraulic control unit.
  • the direction of movement of the hydraulic cylinders is basically determined by the main switching valve, i.e. raising or lowering of the press plate, depending on the direction in which the hydraulic cylinders are loaded with hydraulic oil.
  • the pressure switching valve also regulates whether only one hydraulic cylinder or both hydraulic cylinders of the cylinder pair are pressurized with hydraulic oil on each side.
  • the hydraulic cylinders are preferably each connected to one another with an upper transverse yoke and/or a lower yoke. These yokes are then each arranged above or below the press housing. In order to allow mobility of the hydraulic cylinders relative to these yokes, spherical bearings and shafts can be provided at the connection points of cylinders and yokes.
  • a guide is preferably provided in the press housing for the movable press plate.
  • triangular, prismatic guide rails can be arranged on the pressing plate in cross-section, which interact with corresponding guide profiles on the inner surfaces of the pressing chamber. This counteracts tilting of the pressing plate when pressing material to be pressed.
  • the pressing plate can tilt due to different resistances of the material to be pressed, ie tilts towards its own principal plane.
  • the invention proposes that the pressing plate be assigned a position sensor which detects an inclined position of the pressing plate and from which position signals can be transmitted to the hydraulic control unit. In this way, the control device and the position sensor can be used to determine if the press plate is in an inclined position that exceeds a predefinable limit value.
  • the control device can then control the hydraulic cylinders in such a way that the tilting is compensated, i.e., for example, hydraulic oil is applied to only one hydraulic cylinder on a leading side of the pressure plate and hydraulic oil is applied to both hydraulic cylinders on the opposite, lagging side of the pressure plate in order to move the pressure plate level again.
  • the hydraulic cylinders of each pair of cylinders are selectively activated individually or together depending on the pressing pressure. This means that either only one or both of the two hydraulic cylinders, which are arranged on one side of the press plate and are mechanically coupled to one another, are controlled to raise and lower the press plate.
  • the power requirement is low, only one hydraulic cylinder of each pair of cylinders is charged with hydraulic oil in order to quickly move the press plate down or raise it again, and when there is a high power requirement, i.e. when compressing the material to be pressed, both hydraulic cylinders of each pair of cylinders are then charged with hydraulic oil.
  • FIG 1 shows a baler 1 with a press housing 3, for example made of steel, and a press chamber 2, whose chamber door 9 forming a front side of the press housing 3 is open here.
  • the chamber door 9 is provided with a filling opening 10 in its upper part. With the chamber door 9 closed, parts to be pressed, such as cardboard boxes, cardboard, packaging or empty plastic beverage bottles, which are found in supermarkets, for example, can be filled into the pressing chamber 2 through the filling opening 10 .
  • the material to be pressed is then moved and compacted in direction R1 by a pressing plate 4, which is shown here in a raised, upper position, preferably strapped with wire or plastic straps and then removed as a pressed bale with the chamber door 9 open.
  • a pressing plate 4 which is shown here in a raised, upper position, preferably strapped with wire or plastic straps and then removed as a pressed bale with the chamber door 9 open.
  • the pressing plate 4 is moved by means of four hydraulic cylinders 5, 6, 7, 8 arranged in pairs on the side of the press housing 3, with in figure 1 only the two hydraulic cylinders 5, 6 are fully visible.
  • the two further hydraulic cylinders 7, 8 are arranged on the side of the press housing 3 facing away from the viewer and are largely covered.
  • the Hydraulic cylinders 5, 6, 7, 8 each have a piston 23 and a piston rod 22.
  • the pistons 23 each have a piston surface 25 on one side and a piston ring surface 24 surrounding the piston rod 22 on the other side. Because the hydraulic cylinders 5, 6, 7, 8 are arranged laterally on the press housing 3, the height of the baler 1 is advantageously low.
  • the overall height is also particularly low due to the fact that the hydraulic cylinders 5, 6, 7, 8 are designed as pulling cylinders, which are acted upon with hydraulic fluid on their piston ring surface 24 during their movement in the pressing direction R1.
  • the side edges of the pressing plate 4 are connected here to four vertical, prismatic guide rails 13 which project upwards beyond the pressing plate 4 and which interact with corresponding guide profiles 14 on the two lateral inner surfaces of the press housing 3 .
  • the two hydraulic cylinders 5, 6 on one side and the two further hydraulic cylinders 7, 8 on the other side are at the top by means of an upper transverse yoke 11 and at the bottom by means of a lower yoke 17 running parallel to the upper transverse yoke below the baling chamber 2 within each cylinder pair and cylinder pair connected to form a pair of cylinders.
  • the upper transverse yoke 11 is connected to the upper side of the press plate 4 .
  • the baler 1 is shown in plan view.
  • the four hydraulic cylinders 5 , 6 , 7 , 8 here engage laterally in pairs opposite one another via the upper transverse yoke 11 on the pressing plate 4 .
  • the hydraulic cylinders 5, 6 on one side and the hydraulic cylinders 7, 8 on the other side are connected to one another by means of the upper transverse yoke 11.
  • a mechanical coupling of the hydraulic cylinders 5, 6, 7, 8 is achieved by the transverse yoke 11.
  • the press shield 4 has four vertical, prismatic guide rails 13 on its lateral edges, which interact with the corresponding guide profiles 14 on the inner surface of the press housing 3 .
  • These guide rails 13 and guide profiles 14 counteract a tilting of the pressing plate 4, since when the pressing plate 4 tilts on the leading side, there is increased frictional resistance of the guide rails 13 there in the guiding profile 14, so that the pressing plate 4 is braked on this side and quasi automatically aligns horizontally again.
  • the four hydraulic cylinders 5 , 6 , 7 , 8 are each connected to the upper transverse yoke 11 via a pivot bearing 16 .
  • FIG 3 is the baler 1 in a perspective view obliquely from the front with an opposite of figure 1 changed viewing direction shown.
  • the press shield 4 of the baler 1 is in the raised position here.
  • two hydraulic cylinders 5, 6 or 7, 8 arranged on one side of the press plate 4 are mechanically coupled to one another. This coupling takes place via the joint bearings 16 which act on the upper transverse yoke 11 here.
  • the guide rails 13 on the edge of the press plate 4 are also connected to one another here parallel to the transverse yoke 11 , which serves to increase the mechanical stability of the press plate 4 .
  • FIG 4 are two adjacent hydraulic cylinders 5, 6 of the in figure 1 visible pair of cylinders shown in a side view, which are connected to each other here via the upper transverse yoke 11 and the lower yoke 17.
  • the joint bearings 16 are used for the articulated connection of these components to one another.
  • the outer piston rod ends of the cylinders 5, 6 with the upper transverse yoke 11 are at the top by means of the joint bearings 16 there and the cylinder housings of the cylinders 5, 6 with the joint bearings 16 there with the lower yoke 17 are at the bottom tied together.
  • figure 5 1 is a hydraulic circuit diagram of the hydraulic system of the baler together with some other parts of the baler to illustrate the hydraulic components and the hydraulic connections of the various components of the baler 1 shown in solid lines.
  • the cuts AA and BB are each laterally in figure 5 shown schematically.
  • a total of four hydraulic cylinders 5, 6, 7, 8 act on the press shield 4 of the baler 1 via the upper transverse yoke 11 in order to move it downwards with the press shield 4 in the pressing direction R1 or to raise it in the opposite direction to the pressing direction R1.
  • the control device 12 in turn is connected via a control line to a main switching valve 19 and can control the hydraulic cylinders 5, 6, 7, 8 via this.
  • the hydraulic system also includes a pressure changeover valve 20, which is connected upstream of the main switching valve 19 and switches depending on the hydraulic pressure
  • the pressure switchover valve 20 is activated in such a way that the other two hydraulic cylinders 6, 7 are also activated and charged with pressurized hydraulic oil, in order then to work with all four hydraulic cylinders 5, 6, 7, 8 to produce a higher, almost twice the pressing force of the pressing plate 4.
  • the control device 12 activates two hydraulic cylinders crosswise, i.e. only the hydraulic cylinders 5, 8 or the hydraulic cylinders 6, 7, for example located in the baling chamber, the other two hydraulic cylinders 6, 7 and 5, 8 are also activated on both sides. This means that a hydraulic oil pump then supplies the hydraulic oil to all four hydraulic cylinders 5, 6, 7, 8.
  • the hydraulic cylinders 5, 6, 7, 8 can be controlled accordingly by the control device 12 and the main switching valve 19 in order to compensate for this tilting .
  • a directional switching valve 21 is used to switch the direction of movement of the hydraulic cylinders 5, 6, 7, 8 and thus the pressing plate 4.
  • a typical baler 1 operating cycle is as follows: Initially, the baler 1 is in a filling state, with the hydraulic cylinders 5, 6, 7, 8 in the raised position, ie in the position they are in when the pressing plate 4 is in its uppermost position for the purpose of filling the baling chamber 2 located.
  • Parts of the material to be pressed are filled manually or mechanically through the opened chamber door 9 into the pressing chamber 2 until a predeterminable fill level is reached, and the chamber door 9 is closed.
  • the hydraulic cylinders 5, 8 or 6, 7 are filled with hydraulic oil by the pump P in the annular space of the cylinders to compress the material to be pressed, which is located below the pressing plate 4.
  • the pump P in the annular space of the cylinders to compress the material to be pressed, which is located below the pressing plate 4.
  • the cylinders 5, 6 and 7, 8 of a pair of cylinders are each mechanically connected to one another. So if the piston rod of one cylinder 5, 8 moves down in the pressing direction R1, then the piston rod of the other cylinder 6, 7 also moves down in the pressing direction R1 - by mechanical power transmission via the mechanical connection.
  • the entrained hydraulic cylinders 6, 7 are filled with hydraulic oil from a hydraulic oil tank of the hydraulic system without pressure via a tank line with a check valve arranged therein due to the resulting vacuum in the replenishment process.
  • the cylinders 5, 8 to be filled with hydraulic oil when the power requirement is low and the pressing pressures are low are arranged crosswise, ie the cylinder 5 is hydraulically connected to the cylinder 8.
  • the cylinders 5, 8 are under pressure in the operating state in which the pressure switching valve 20 has not yet switched over to the filling of all cylinders 5, 6, 7, 8 standing hydraulic oil.
  • the pressing plate 4 moves down relatively quickly in the vast majority of the pressing cycle, without building up much pressure.
  • the pressure for pressing the material to be pressed is only required in the lower part, approximately the lower third to fifth, of the pressing chamber 2 when the pressing chamber 2 is already reasonably full.
  • the hydraulic oil flow is then released not only into the hydraulic cylinders 5 and 8 via the pressure switching valve 20, but also the respective adjacent hydraulic cylinders 6 and 7 are supplied with pressurized hydraulic oil.
  • the pressing plate 4 is already in the lower part of the pressing chamber 2.
  • the cylinder pairs 5, 6 and 7, 8 on each side of the pressing plate 4 are connected via the transverse yoke 11, which is located above the pressing plate 4, connected to each other.
  • the guide rails 13 are located on the pressing shield 4 and work together with the compatible, pronounced guide profiles 14 in the side walls of the pressing chamber 2 . If now z. If, for example, a different pressure builds up under the right-hand part of the pressing plate 4 than under the left-hand part, then the pressing plate 4 is pulled at an angle because the cylinders 5, 6 or 7, 8 on one side receive less oil than the cylinders 7, 8 or 5, 6 the other side.
  • the control device 12 Direction switching valve 21 of the hydraulic system is set to return and the pressing plate 4 moves back to its upper starting position. At the latest at the end of the retraction, the pressing plate 4 aligns itself horizontally again by running against an upper stop, after which it can then be moved back down from there for a new pressing step.
  • the press plate 4 At the end of the last pressing step, i. H., when a pressed bale has been pressed, the press plate 4 is in its lower position. In this position of the press shield 4, the press bale can be tied in a manner known per se. From this position, after switching over the direction switching valve 21, the pressing plate 4 is moved back upwards again. In this case, too, only two cylinders 5, 8 are acted upon by hydraulic oil in the return, so that due to the small volume of hydraulic oil required for this, the pressing plate 4 can be returned relatively quickly in the upward direction.
  • the twin cylinder 6, 7 connected to the cylinder 5, 8 that is acted upon in each case is not moved upwards by the pressurized hydraulic oil flowing into its pressure chamber, but is carried along by the respective adjacent hydraulic cylinder 5, 8 due to the mechanical connection and due to the force transmission taking place via it.
  • the hydraulic oil released in the annular space of the hydraulic cylinders 6, 7 runs into the pressureless hydraulic oil tank.
  • the hydraulic cylinders 6, 7 are only connected to the hydraulic oil tank on their bottom side via pure leakage oil lines and can also draw air when the cylinders 5, 8 are extended.
  • the piston space of the entrained hydraulic cylinders 6, 7 therefore never needs to be charged with pressurized hydraulic oil.
  • the chamber door 9 can be opened and the pressed and tied bale can be removed from the pressing chamber 2.
