Definitions

  • the invention relates to a press for compacting material, in particular waste, by means of a stamp or a press plate which is displaceable in a chamber and is driven by at least one cylinder-piston unit which lies to the side of the chamber and in the starting position, in that the material has not yet been compacted, retracted and extended in the end position in which the material is maximally compressed.
  • Document DE-U-8709274 describes a construction which has a hydraulic drive consisting of two servo devices arranged laterally next to the press housing in the upper region thereof, each in the form of an axis parallel to the latter, inserted in a cylinder and loaded on both sides by pressure medium, the piston of which Piston rods are operatively connected to the compression plate via an angle lever.
  • a hydraulic drive consisting of two servo devices arranged laterally next to the press housing in the upper region thereof, each in the form of an axis parallel to the latter, inserted in a cylinder and loaded on both sides by pressure medium, the piston of which Piston rods are operatively connected to the compression plate via an angle lever.
  • the object of the invention is to improve a press of the type mentioned in such a way that it has a large stamp travel or a large chamber volume with a small external dimension and a high safety against tipping of the stamp despite maximum pressure with a simple construction.
  • stamp or a stamp carrier is not attached to a piston rod, but to the cylinder itself, specifically at the end of the cylinder at which the piston rod emerges.
  • the cylinder is parallel and to the side of the path on which the stamp moves.
  • Such a construction means that the cylinder-piston units are not or not substantially in the direction of the ram path beyond the press in the retracted state, so that the external dimensions of the press are neither in the retracted nor in the extended position are much larger than the chamber volume.
  • one cylinder end is at the level of the stamp position in which the stamp is in an initial position and the other cylinder end is at the level of the stamp position in which the stamp is in its end position.
  • the stamp has a cross member which is attached to the cylinder-piston units, in particular to the cylinders, and carries at least one cylinder-piston unit, to which the stamp press surface is attached and can be moved further into the compression chamber.
  • This additional cylinder-piston unit an even stronger compression of the material can be achieved.
  • the greatest advantage of all embodiments is that the piston side is always pressurized to generate the pressing force, which is opposite the piston rod attachment, so that the cylinder-piston units can apply a maximum pressure during material compression. The return stroke without the pressing process then takes place with the lower pressure on the ring side of the cylinder.
  • each cylinder has a guide on its outside.
  • the guide of the cylinder can be formed by a tube which coaxially surrounds the cylinder and into which the cylinder is most extended in its final pressing position.
  • the guide tube can also extend approximately over the height of the machine and have a slot in its upper half for the fastening part of the stamp.
  • the in the Cylinder-piston leading pressure lines run through the interior of the piston rod.
  • the pressure lines can be bores in the piston rod.
  • the pressure lines can also be hose or pipe lines inside the piston rod.
  • a particularly tip-proof design is created when a cross element is fastened to the cylinder-piston unit, in particular to the cylinder, at each end of which a fastening element is fastened, which is connected to the stamp or the press plate, each fastening element in a separate slot in the chamber wall slides.
  • the height of the cylinder-piston units is adjustable and preferably the punch (press plate) is attached to the cylinder at a distance from the upper end of the cylinder.
  • the piston rods which are elongated upwards to lift the cylinder-piston unit, can have threads, in particular sawtooth threads, on each of which a wheel with an internal thread is screwed, all wheels being driven synchronously, in particular by a chain.
  • the press has a cuboid chamber 1, in which a horizontal punch or a press plate 2 can be moved up and down vertically, the horizontal cross section of which corresponds to the inner cross section of the chamber 1.
  • a cylinder-piston unit 3, each having a cylinder 4, a piston 5 and a piston rod 6, are vertically fastened on sides opposite one another outside the chamber 1.
  • the end 6a of the piston rod 6 emerging from the cylinder is fastened to a horizontal cross member 7 which is fastened to the bottom or the top of the chamber 1.
  • the piston rods 6 with the piston 5 are thus immovably attached to the side of the chamber 1 and at Applying a pressure medium, in particular a hydraulic fluid on the piston side opposite the piston rod 6, both cylinders 4 move downwards. In doing so, they take the stamp 2 with them, which is attached to the cylinders 4 at the cylinder ends on opposite sides, at which the piston rods 6 exit.
  • This further cylinder-piston unit 9 can also be arranged on the opposite side of the chamber 1, as shown in FIG. 3. Then the material located between the two pistons 2, 2 a is compressed from two sides.
  • the press according to FIG. 2 is arranged lying horizontally, the chamber 1 having a door 12 on the side opposite the stamp, which is firmly closed during the pressing process and can then be opened in order to take out the compacted material to be able to.
  • a door is arranged in two parts in the presses of FIGS. 1 and 2 on the front of the chamber 1.
  • Each cylinder can have a guide on its outer edge.
  • the guidance of the cylinder is in this case formed by a tube which coaxially surrounds the cylinder and into which the cylinder is most extended in its final pressing position.
  • the guide tube extends approximately over the height of the machine and has a slot in its upper half for the fastening part of the stamp.
  • the pressure lines leading into the cylinder-piston unit run through the interior of the piston rod.
  • the pressure lines can be bores in the piston rod.
  • the pressure lines can also be hose or pipe lines inside the piston rod.
  • a cylinder-piston unit 3 is arranged only on an outside of the chamber 1.
  • a cross element 13 is fastened to the cylinder-piston unit, in particular to the cylinder 4, which projects on both sides of the cylinder 4 and on each end of which a profile-shaped fastening element is fastened.
  • the two fastening elements each protrude through a slot 15 through the chamber wall 19 and are fastened to the punch 2 or to the press plate.
  • a roller 14, which runs in the respective slot 15, can be mounted on each fastening element.
  • each slot is preferably reinforced on the outside by U-shaped profiles 18 on which the roller runs.
  • the two fastening elements 12 form together with the stamp or the Press plate 2 is a U-shaped, rigid element.
  • a hydraulic line lies in the hollow piston rod 6, and the space, in particular with an annular cross section, between the outside of the hydraulic line and the inside of the piston rod inner wall is used as a further hydraulic line.
  • FIG. 6 shows elongated piston rods 6 with a sawtooth external thread and two chain wheels 20 mounted on the housing or machine frame, which can be rotated simultaneously with the aid of a chain 21.
  • the press plate 2 is attached somewhat lower to the cylinder 4 in order to be able to press smaller bales. If the entire unit is raised above the sprockets, bales as large as shown in FIG. 1 can then be produced (pressed), with full use of the maximum chamber height.
