Definitions

  • the innovation relates to a vibrating piston press with an arc-shaped press channel, in which a press piston arranged to oscillate about an axis is moved back and forth by means of a hydraulic piston-cylinder unit, the piston rod of which is articulated on the press piston, while the cylinder of which is pivotally mounted on the press channel.
  • a hydraulically driven press piston can be pivoted about a vertical axis.
  • the material should be fed in by hand from above.
  • the piston-cylinder unit is articulated on the press channel and the press piston in such a way that the effective lever arm length between the piston pin and the piston oscillation axis remains essentially unchanged during the press stroke. Because of this design, only relatively low compression densities can be achieved with a given power requirement.
  • the cylinder arrangement requires a relatively large dimensioning of the baling chamber housing. It is also disadvantageous that the feed is to be carried out directly into the baling channel by hand, which entails the risk of accidents, allows only low throughputs and no longer meets today's comfort requirements.
  • a mechanically driven vibrating piston press provided with a positive feed device is known from DE-OS 39 19 434.
  • the disadvantage here is above all the relatively high construction costs, in particular in the case of the main transmission, when the press channel cross sections are approximately 1 square meter, as has been required recently.
  • the innovation is based on the task of developing a vibrating piston press in such a way that, with a compact design of the press, also large-volume cardboard boxes and others Bulky goods with better use of power than before processed quickly.
  • the piston rod is subjected to tension during the press stroke movements of the press piston and in its extended position includes an acute angle with the connecting line between the press piston pivot axis and the pin.
  • the plunger moves slowly into the end position and can exert high pressing forces despite the relatively low drive power, while the plunger moves faster on its return stroke and thereby releases the filling opening longer, so that even larger cardboard boxes can be processed safely.
  • the design as a traction piston results in a very space-saving design of the vibrating piston press.
  • a preferred embodiment of the invention is that the piston-cylinder unit is double-acting and that for the return stroke of the plunger, both cylinder spaces are acted upon by a common oil line.
  • the return stroke speed of the plunger can be increased despite the low oil flow, so that the filler opening is open for loading as long as possible.
  • a favorable construction is achieved in that both cylinder spaces are connected to one another via a connecting line, and in that a controllable shut-off valve is arranged in the connecting line, which interrupts the circulation connection between the two cylinder spaces during the application of the cylinder chamber on the piston rod side.
  • the further embodiment provides that the plunger can be swiveled about a horizontal axis located below the press channel and interacts with a feed device which, in time relation to the plunger, conveys the material supplied via a feed table through a filling opening into the press channel. This results in a compact size of the press, which can be transported to the installation site in the existing elevators of the department stores without major disassembly.
  • a baling chamber housing 1 is built on support feet 2 and has a rectilinear baling channel section 3 and an arch-shaped baling channel section 4, in which a baling piston 6, which is mounted to oscillate about a horizontal axis 5, moves back and forth between an upper position 7 drawn in solid lines, and one lower position, drawn in dash-dot lines 8.
  • the upper wall 9 of the press channel section 4 has a filling opening 10, which is preceded by a feed space 11.
  • the plunger 6 completely releases the filling opening 10 in its lower position 8.
  • the feed space 11 is formed by a feed table 12 which extends between two side walls 13 and opens into the press channel section 4 at a distance above the lower position 8 of the plunger 6.
  • a conveyor belt 15 rotating uniformly in the direction of arrow 14 is arranged in the feed table 12.
  • the transition from Conveyor belt 15 to the filling opening 10 is carried out by a roller and a fixed platform 16, which ends shortly before the movement path of the plunger 6 with a bend and forms the lower edge of the filling opening 10.
  • a feed device 18 is arranged above the filling opening 10 and is driven in a temporal relationship to the plunger 6.
  • the plunger 6 is driven by two piston-cylinder units 19; one is arranged outside the side wall 13.
  • a piston rod 20 is in each case pivotally mounted on a bolt 22 which is welded to the side of the plunger 6 and which extends outwards through an elongated slot 21 in the side wall 13, while the cylinder 23 is mounted on a cross member fastened to the compression channel 3 by means of a pin 24.
  • the arrangement is designed so that the piston rod 20 is retracted into the cylinder 23 in the upper position 7 drawn in solid lines of the plunger 6 and in the lower position 8 of the plunger 6 with a connecting line 25 between axis 5 and pin 22 an acute angle X includes.
  • the piston-cylinder unit 19 is double-acting and has an oil line 26 for acting on the piston rod-side cylinder space 27 (piston ring surface) and a second oil line 28 for acting on the piston-side cylinder space 29, which may serve as a return oil line. Both oil lines 26, 28 can also be coupled by a common oil line 30, which is shown in dashed lines, and pressurized oil can be applied at the same time. As a result, the oil from the cylinder chamber 27 on the piston rod side flows into the cylinder chamber 29 on the piston side, as a result of which the piston rod 20 retracts quickly despite the relatively small amount of oil flow.
  • a hydraulic unit 32 is arranged below the feed table 12.
  • the operating principle of the vibrating piston press is as follows: The plunger 6 is in the lower position 8, the piston rod 20 is extended. The conveyor belt 15 and the feed device 18 move in the direction of the arrows 14, 31 and push the cardboard waste to be pressed through the filling opening 10 into the press channel 3. After a predetermined number of strokes of the feed device 18, the oil line 26 is pressurized with oil. The plunger 6 moves from its lower position 8 to the upper position 7, oil flows from the cylinder chamber 29 into the oil line 28, which now serves as a return oil line.
  • the plunger 6 Due to the angular assignment of the plunger pivot axis 5 and the articulation point 22 of the piston rod 20, the plunger 6 initially moves quickly with small forces, whereas where high press forces are required, the plunger 6 moves at low speed with the maximum effective lever arm length (upper press position 7). After reaching the upper position 7 of the plunger 6, the oil line 30 is supplied with pressurized oil, so that both cylinder spaces 27, 29 are acted upon and the plunger 6 is quickly returned to its lower position 8. A new filling cycle begins. When the bale length is reached, the bale is tied in a manner known per se.
