Definitions

  • the invention relates to a baling press according to the preamble of patent claim 1.
  • baler can be seen, through which a piece of goods filled in a baling chamber of the baler, in particular cardboard boxes, grass, earth or other objects, are compressed by means of a ram.
  • the ram is mounted in a housing of the baling press so that it can move axially and can thus be moved in the direction of the pressing chamber by means of hydraulic fluid.
  • the press plunger By immersing the press plunger into the press chamber, the objects placed there are compacted and pressed into a bale, which is tied together, for example by means of a wire loop strapped in the longitudinal direction of the housing, and can then be removed from the housing of the baler through a door opening.
  • baling presses have proven themselves in practice, but considerable hydraulic forces are required for the delivery of the press ram.
  • the length of the baling press has to be adapted to the spatial conditions of a customer and is therefore limited, so that the lifting distances of the press ram often cannot exceed a predetermined distance. From the aforementioned disclosure are therefore proposals for the arrangement of multiple press rams and their hydraulic circuits for their operation. In this case, several of these rams are arranged next to one another and are operated or controlled depending on the position of the respective ram.
  • the operating states of the press ram can be defined such that the filled material, in particular cardboard boxes, is displaced in the press chamber by means of the press ram.
  • An increased pressing force of the press ram is only required when enough objects have been compacted in the pressing chamber and the bale is to be formed.
  • baling press which has several press rams, which are operated by means of a control device depending on the position of the objects in the pressing chamber and depending on the number of these objects filled in, whereby on the one hand a rapid infeed movement for compacting the filled objects in the pressing chamber and on the other hand a pressing force can be built up by which the compacted objects are pressed together into a bale with the desired external dimensions.
  • this described baling press consists of several press rams in order to be able to generate the necessary compression force that acts on the objects to produce the bale.
  • the individual pressure chambers of the respective ram are filled with hydraulic fluid, causing time delays because the individual pressure chambers and the associated delivery of the ram require energy or force, the respective generation or transmission of which is time-consuming.
  • the ram consists of a tube which is supported on a support plate connected to the housing and in which a pressure piston with a T-shaped cross section is mounted so that it can move axially, from a carriage which is assigned to the open end of the pressure piston and which is fastened to the pressure piston, and consists of a stationary cylinder enclosing the pressure piston and the carriage, that the tube and the cylinder are attached to a support plate connected to the housing, that the support plate and the tube form or enclose a first pressure chamber, that the support plate, the outside of the tube , the first free surface of the carriage and the inside of the cylinder form or enclose a second pressure chamber, that the outside of the pressure piston, the second free surface of the carriage and the inside of the cylinder form or enclose a third pressure chamber, and that in each of the three pressure chambers an opening is incorporated, which with the hyd connected to the hydraulic circuit, on the one hand a fast infeed movement of the pressure piston is achieved in order to compress the filled objects
  • the second pressure chamber is filled with hydraulic fluid by means of a second pump, which creates an additional pressure force that acts on the freely accessible pressure chamber facing the second surface of the slide acts.
  • a third pressure chamber is provided, which runs between the outside of the pressure piston, the carriage and the inside of the cylinder. Hydraulic fluid is pressed into this third pressure chamber via a third opening, which fluid acts on the surfaces of the carriage facing the third pressure chamber and pushes this and consequently also the pressure piston back into the starting position. A squeezing force acts on the hydraulic fluid present in the first and second pressure chambers, as a result of which the hydraulic fluids are pushed back from the first and second pressure chambers into the reservoir.
  • baling press 1 Out of figure 1 a baling press 1 can be seen, through which objects 6 are pressed into a bale 9 .
  • the bale 9 is strapped with a wire loop 40, which is to be arranged or aligned in the longitudinal direction 3 of the baling press 1 in order to prevent the individual objects 6 from falling apart.
  • the baler 1 consists of a housing 2, through which a pressing chamber 4 is formed with five side walls. One of the side walls of the pressing chamber 4 is closed by means of a door 5 which can be opened in order to remove the bale 9 with the strapping 40 can.
  • the baling press 1 includes a funnel opening 7 through which the isolated objects 6, for example cardboard boxes or other waste products, can be thrown into the baling chamber 4.
  • the baling press 1 is assigned an axially movable press ram 8 which closes the last open side of the cuboid press chamber 4 and thus faces it.
  • the ram 8 By the linear movement of the ram 8 are the loose objects 6 present in the pressing chamber 4 are pressed in the direction of the door 5, which accordingly serves as a stop in the closed state.
  • the more individual objects 6 are present in the pressing chamber 4 the more densely they are compressed by the linear movement of the pressing ram 8 . Consequently, the pressing ram 8 has to continuously perform a rapid linear movement from the starting position to an end position in order to compact the objects 6 that have been filled in in a number of cycles.
  • a hydraulic circuit 11 which is operated or controlled by a control device 18 depending on the respective position of the ram 8 .
  • the ram 8 consists of a tube 21 which is attached to a support plate 25 connected to the housing 2 .
  • the tube 21 and the support plate 25 form a first pressure chamber R 1 which is connected to the hydraulic circuit 11 via an opening 15 .
  • a pressure piston 22 On the outside of the tube 21 there is a pressure piston 22 which is mounted so that it can move axially.
  • a carriage 23 At the second free end of the pressure piston 22, which is opposite the pressure surface A 1 , a carriage 23 is provided or attached thereto.
  • the carriage 23 has two exposed surfaces identified as print surfaces A 2 and A 3 .
  • the tube 21, the pressure piston 22 and the carriage 23 are arranged inside a cylinder 24.
  • the cylinder 24 is connected to the support plate 25 .
  • the diameter of the pressure piston 22 and the carriage 23 correspond approximately to the diameter of the cylinder 24.
  • the carriage 23, the cylinder 24 and the support frame 25 enclose a second pressure chamber R 2 in which an opening 16 is incorporated, whereby the pressure chamber R 2 is coupled to the hydraulic circuit 11.
  • the pressure piston 22, the carriage 23 and the cylinder 24 enclose a third pressure chamber R 3 .
  • a cover 26 is attached to the free end of the cylinder 24 facing the pressing chamber 4 .
  • An opening 17 is worked into the wall of the cylinder 24 in the area of the cover 26 , which opening thus opens into the third pressure chamber R 3 and which is connected to the hydraulic circuit 11 .
  • the support frame 25 is fastened to the housing 2 of the baling press 1 so that both the pipe 21 and the cylinder 24 are supported on the housing 2 in a position-oriented manner.
  • the hydraulic fluid 20 is sucked from the reservoir 10 into a pressure line 19, which is connected to the pump 31, since the pump 31 is switched on.
  • a first pumping and suction device 12 of the hydraulic circuit 11 has two branches, in each of which a control valve 35 is used.
  • the first control valve 35 relative to the pump inlet 31 is in the direction of the pump 31 is opened and the drain lines 19' branching off from it are closed.
  • the second control valve 35 is also switched accordingly by the control device 18, so that the hydraulic fluid 20 flows into the first pressure chamber R 1 at a predetermined pressure.
  • Both the pumps 31, 32 and 33 and the control valves 35 of each of the three pumping and suction devices 12, 13 and 14 are connected to the control device 18 by means of electrical lines 34 and can consequently be controlled or regulated accordingly by the latter. Due to the pressure prevailing in the first pressure chamber R 1 , the hydraulic fluid 20 flows into the pipe 21 and presses against the contact surface A 1 of the pressure piston 22 , as a result of which the latter is moved in the direction of the pressure chamber 4 .
  • the second pumping and suction device 13 is switched in such a way that the hydraulic fluid 20 is sucked from the reservoir 10 directly into the second pressure chamber R 2 .
  • the pressure line 19, in which the pump 32 is arranged, is closed by means of the two control valves 35.
  • the infeed movement of the pressure piston 22 and the carriage 23 attached to it creates a negative pressure in the second pressure chamber R 2 , which sucks the hydraulic fluid 20 out of the reservoir 10, since the discharge line 19' is opened or released by the control valves 35 is.
  • the third pumping and suction device 14 is fully open. This means that the pressure line 19, in which the pump 34 is installed, is closed by the control valves 35, so that the hydraulic fluid 20 is pressed out of the third pressure chamber R 3 through the discharge line 19' into the reservoir 10. This is because the second surface A 3 of the carriage 23 presses the hydraulic fluid 20 introduced into the third pressure chamber R 3 out of the latter when the pressure piston 22 and the carriage 23 are advanced.
  • a corresponding feed and return movement for the pressure piston 22 can be set.
  • the hydraulic fluid 20 is completely pressed out of the third pressure chamber R 3 and the cover 26 serves as a stop for the movements of the pressure piston 22 and the carriage 23.
  • the pressing force is therefore exerted both by that in the pressure chamber R 1 and by that in the pressure chamber R 2 prevailing pressure and the pressure areas A 1 and A 2 generated.
  • the last objects are thrown into the pressing chamber 4 so that the distance between the pressure piston 22 and the objects 6 already present is filled by them, whereby the pressing effect can be influenced.
  • the first and second pumping and suction devices 12 and 13 In order to move the pressure piston 22 back into its starting position, the first and second pumping and suction devices 12 and 13 must be opened and the third pumping and suction device 14 activated.
  • the pressure lines 19, in which the pumps 31 and 32 are installed are closed by the control valves 35 and the discharge lines 19', which run parallel thereto, are open. Consequently, the hydraulic fluid 20 present in the two pressure chambers R 1 and R 2 can flow into the reservoir 10 without resistance.
  • the third pump 33 is switched on and the control valves 35 of the third pumping and suction device 14 close the discharge line 19'. Consequently, the pump 33 presses the hydraulic fluid from the reservoir 10 into the third pressure chamber R 3 .
  • the pressure prevailing there and the surface A 3 of the carriage 23 facing the third pressure chamber R 3 result in a restoring force, whereby the carriage 23 and the pressure piston 22 attached thereto are moved back in the direction of the support plate 25, ie in its starting position.
