Definitions

  • the invention relates to a baling press, as is often used for compacting and pressing loose material, for example packaging films, cardboard boxes or plastic bottles intended for recycling, for example in the logistics sector and often also by supermarkets for their packaging materials.
  • the pressing direction is approximately parallel to the plane of the removal opening, the pressing direction is often vertical from top to bottom.
  • the removal door is usually arranged approximately vertically.
  • the present invention deals with box balers, in which there is a lockable removal door that must withstand the pressing pressure during pressing operation, and in particular their opening mechanism.
  • Swing doors have the advantage that when open they do not require any additional height, i.e. beyond the press box, but in order to be able to withstand the pressing pressure, when closed they require a stable and complex locking device, which is usually released manually before the door is opened must.
  • a sliding door has the advantage that it does not necessarily require such an additional locking mechanism as long as the guides of the sliding door are solid.
  • the disadvantage of the sliding door is that when open it requires additional space either in the height or in the width of the press box, and the shifting of the entire door weight to open usually requires a working cylinder such as a hydraulic cylinder, and not opened by hand can be.
  • This lifting movement is also necessary so that the grooves machined into the contact surface of the sliding door and the strapping wires of the fully strapped bales located therein can come out of these grooves when the door is opened.
  • a box baler which can be closed by a sliding door on the front side opposite the press ram.
  • a baler is also known in which a sliding door closing the press channel has surface areas that are inclined to the contact surface according to Figures 8 and 9, but it is clearly stated in column 7, line 31 that the sliding door 70 always maintains the same longitudinal position when it closes (in the transverse direction).
  • this task is solved in that the sliding door is moved between the open position and the closed position along door guides that run straight, at an acute angle to the opening plane of the removal opening, which is closed by the sliding door in the closed position .
  • this opening plane runs perpendicular to the direction of the pressing box, which is also the pressing direction when the pressing direction is directed towards the removal opening.
  • this angle is relatively small, i.e. less than 30°, better less than 20°, better less than 10° or even less than 5°, it is possible to design and arrange the cross-section of the threading grooves in the sliding door for the strapping element in such a way that that when the sliding door is opened, the in these Threading groove sections of the strapping element - a strapping band or strapping wire - can slide out of the opening of the cross section of the threading groove without the need for a first lifting movement of the sliding door essentially perpendicular to the plane of the removal opening.
  • the movement that the sliding door has to make when opening and closing is an exclusively straight movement, which greatly simplifies the construction:
  • the direction of action of the door drive - no matter what it is made of - can be arranged parallel to the guiding direction of the sliding door, i.e. its direction of movement when opening or closing.
  • a hydraulic cylinder In the case of a door drive, consisting of one or more working cylinders, usually hydraulic cylinders, such a hydraulic cylinder can be arranged on both sides of the press housing in a direction that corresponds to the guide direction in which the guides for the sliding door run, so that such a working cylinder can also be arranged Its two ends do not have to be attached in an articulated manner to the sliding door on the one hand and to the press housing on the other, but a rigid attachment is sufficient.
  • individual, small-area guide pins on the sliding door are not necessary in order to guide them in separate link guides and to realize the lifting movement, but rather the guide elements on the sliding door and/or the door guides can extend over a large part - at least 40%. better at least 60%, better at least 80%, better at least 90% - of the extension direction of the sliding door in the guide direction, for example forming a guide bar or a guide groove.
  • the door guides should be present over as large a proportion as possible of the extension of the sliding door in the guide direction and, in particular, be present continuously.
  • This guide element does not have to extend over the entire extent in the guide direction, but can consist of individual elements - although this is disadvantageous in terms of production technology - and could theoretically also consist of a large number of guide pins spaced slightly apart from one another, but the total area in which the guide elements are Sliding door rests against the door guides in the closed position, many times larger than when only two guide pins are installed on each side in a respective link guide.
  • the guide unit consisting of a guide element and door guide can itself absorb much higher loads across the door plane than just two relatively small guide pins, so that for reasons of stability alone, a sliding door designed in this way does not require an additional support device in the form of a locking device to absorb the pressing forces .
  • Securing the closed position can also be achieved in a simple manner by using the door drive, for example the hydraulic cylinder, to move the sliding door into the closed position, usually in the form of a stop in the door guides, and in this position the closing and/or or discharge line of the working cylinder is closed by a valve.
  • the tightness of the working cylinder is sufficient to prevent the sliding door from opening unintentionally, caused by the pressing forces, due to the angle mentioned at the beginning being as small as possible between the direction of movement of the door and the opening level of the removal opening on the press housing.
  • the guide unit formed from guide elements and door guides is designed to be self-locking, but at least designed in such a way that only a very small additional holding force, in particular of less than 50 N, in particular of less than 30 N, is required to hold the sliding door, especially at the maximum possible Keep the pressure of the press plate against the resulting bale in the closed position.
  • the locking mechanism can be opened before the sliding door starts moving.
  • the pressure on the sliding door should of course soon decrease with increasing movement out of the closed position, which is why the angle between the direction of movement of the sliding door and the opening plane of the removal opening should be at least 1 °, better at least 2°, better at least 3°.
  • a working cylinder is preferably arranged on both sides of the removal opening.
  • reaching the end position of the sliding door in the open position should also be detected, because only in response to this signal should the control cause the bale to be pushed out through the then open removal opening, which is usually done by the press plate itself or an ejector arranged in the press plate. Piston with a reduced end face takes place.
  • a position sensor for example a cable pull sensor or a contactless sensor, such as a magnetostrictive sensor, which is also good can be arranged protected inside the hydraulic cylinder.
  • pieces of the strapping element are usually cut to length Outside of the press box, threading grooves formed through corresponding openings and in the inner surfaces of the press box and the press plate are pushed around the bale, preferably in a horizontal plane, until the front end protrudes again through this opening in the wall of the press box, so that the two ends are connected to each other can be connected.
  • the upper groove flank can reach down at least to the free end of the lower groove flank, in particular partially or preferably completely covering it in the pressing direction.
  • the acute angle at which the groove flank adjacent to the press box lies to the opening plane is preferably equal to or greater than the acute angle between the sliding door and the upper groove flank.
  • the groove flank facing away from the press box also runs at an acute angle to the opening plane, which is preferably equal to or greater than the angle between the upper groove flank and the opening plane.
  • a box baler - especially if it is designed as described above - can be operated to open the sliding door in such a way that this sliding door is moved in an overall straight and not curved guide direction between the open position and the closed position.
  • the contact surface of the sliding door is always in a parallel position to the opening plane when opening or closing.
  • a locking device Even if a locking device is present, it can be designed in such a way that it does not have to be unlocked beforehand and in particular not manually before the opening movement of the sliding door is effected by means of the door drive, but rather by coupling the door drive with the locking device, in particular its unlocking element , this can be done automatically by the door drive together with the door opening.
  • FIGS. 1a - 3 show a box baler 1, as is known from the prior art.
  • Such a box baler 1 comprises a press box 50 running in the longitudinal direction 10, usually the horizontal direction, which is delimited by the left and right side walls 2a, 2b of the press housing 2 as well as the upper wall 2c and the lower wall 2d.
  • the pressing direction 10 ' is directed from right to left along the longitudinal direction 10, so that the left end of the press box 50 is open and can be closed by a sliding door 5 in this case, while the right end of the press box 50 is movable in the longitudinal direction 10 Press plate 3 is limited.
  • the rear, here right, end of the press housing 2 is closed by a permanently mounted rear wall between the side walls 2a, 2b and the upper wall 2c and lower wall 2d, on which the press cylinder 16 attached to the back of the press plate 3 is supported.
  • the loose material 99 enters the press box 50 through a transition opening 51 ', which is present approximately in the longitudinal direction 10 in the central region of the upper wall 2c, with a filling funnel 25 being placed on the transition opening 51 ', in the upper filling opening 51 of which the material 99 is placed is thrown in.
  • the filling opening 51 of the filling funnel 25 is usually larger than the transition opening 51 'from the filling funnel 25 through the top wall 2c into the press box 50, with the filling funnel 25 also serving as a storage space for materials 99 to be pressed.
  • the press plate 3 is moved back and forth and in particular moved forward in the pressing direction 10 'by means of a press cylinder 16 arranged behind the press plate 3 in the pressing direction 10', or several press cylinders 16 as in Figure 1b indicated, which are supported on the rear wall of the press housing 2.
  • press plate 3 is guided in the press box 50 by being attached to the front of a press carriage 15 in the pressing direction 10 ', which moves, for example, by means of rollers 17 on the lower wall 2d of the press housing 2.
  • a cover plate 15a extends backwards against the pressing direction 10 ', which, when viewed from above, extends from the filling funnel 25 into the press box 50 at least over the width of the transfer opening 51' - the length of which is dimensioned such that In the pressing position that is at the forefront in the pressing direction 10' and can be reached through the press plate 3, the underside of the transfer opening 51' is still closed by the filling funnel 25 in the press box 50 in order to prevent loose material 99 located in the filling funnel 25 from slipping into the area behind the pressing plate 3 impede.
  • the upper transverse edge of the press plate 3 is designed on its front surface as a knife edge 3a, which shears off material 99 located in the area of the transfer opening 51' compared to the one in Pressing direction 10 'front edge of the transfer opening 51', which can also be designed as a counter knife on its lower edge.
  • bale 100 When strapping the finished bale 100 in the closed press box 50, strapping wires cut to length are guided around the bale 100 in a horizontal plane in several, here four, levels one above the other, and their ends on both sides are connected to one another, so that a closed, relatively tight A strapping ring attached to the bale 100 is created.
  • the bale 100 expands slightly, which is initially only possible in the longitudinal direction 10 in the press box 50, whereby the closed strapping rings made of strapping material are tensioned.
  • the respective strapping wire 20 is guided around by the fact that several longitudinal grooves 21 which run at a distance from one another in the longitudinal direction 10 are incorporated into the inner surfaces of the side walls 2a, 2b of the press housing 2, and also at the same height - with the sliding door 5 in its closed state - threading grooves 12 horizontal, but running transversely to the longitudinal direction 10.
  • Analog threading grooves 12 are incorporated into the front surface 3a of the press plate 3 at the same height, i.e. also aligned with the ends of the longitudinal grooves 21.
  • the strapped bale 100 can be pushed out of the pressing box 50 through its removal opening 52, for example onto a pallet 18, and transported away with a forklift. since the strapping rings 20 placed around the bale 100 can move out of the grooves 12, 21.
  • the sliding door 5 performs a movement in the direction of movement 4 ', namely initially a lifting movement, in which the sliding door 5 is moved away from the removal opening 52 at a relatively large angle to the opening plane 52 ", but only over a relatively short distance Distance, and then moved up parallel to the opening plane 52" to release the removal opening 52.
  • the lifting movement serves to remove the remaining pressure still on the sliding door 5 from the sliding door 5 and, above all, to allow the strapping wires 20 lying in the threading grooves 12 of the sliding door 5 to slide out of them without any problems, so that the opening of the Groove cross section 13 of these threading grooves 12 can remain small.
  • the cross-sectional shape 13 of the threading grooves 12 is generally still rectangular with two horizontally extending, mutually parallel flanks.
  • the locking device must be unlocked manually before the sliding door 5 is raised, which may require a lot of effort given the pressing force on the sliding door 5.
  • the sliding door 5 is moved in height by means of a hydraulic cylinder 7 as a door drive 6 on each side of the sliding door 5, the lower end of which is connected to the press housing 2 and the upper end of which is connected to the upper end of the narrow outside of the sliding door 5 .
  • the hydraulic cylinder 7 is at a different angle to the pressing direction 10 ' viewed in the side view when the sliding door 5 is raised and open than in the closed position. Therefore, the hydraulic cylinder 7 must also be attached to the press housing 2 at its lower end so that it can pivot about an axis running in the horizontal transverse direction.
  • FIGS. 4a - 6b show the solution according to the invention, in which the direction of movement 4 'of the sliding door 5 when opening and closing is a consistently straight direction, with a relatively small, in any case acute, angle ⁇ between the direction of movement 4' and the opening plane 52 ", viewed in the Side view in the longitudinal direction 10 as in Figure 4a .
  • guide elements can be used that extend over a significantly larger guide area than the guide pins 23 in the prior art: So on both sides of the sliding door 5 - as best in Figure 4b to recognize - a guide bar 9 protrudes outwards, which, when viewed from the side, has two mutually parallel flanks, both of which extend in the direction of movement 4 'and are therefore straight.
  • the guide bar 9 can extend over the entire height of the sliding door 5 and, when the sliding door 5 is closed, even upwards beyond the upper end of the removal opening 52.
  • a strip-shaped door guide 4a to be arranged on the press housing 2 - viewed from the side outside the press box 50 when viewed from above - especially in the pressing direction 10 'behind the guide bar 9, which is also located outside the press box 50 when viewed from above and extends over the entire height of the press box 50 and even beyond.
  • a door guide 4b preferably also strip-shaped, on the side facing the pressing force, but this can only be present in the upper area, possibly only above the height of the press box 50 can or over the entire height if this door guide 4b is also located laterally outside of the press box 50 when viewed from above.
  • the sliding door 5 is actuated by hydraulic cylinders 7 that are essentially upright on the side outside of it - the upper fastening end of the hydraulic cylinder 7 also moves in the direction of movement 4 'and therefore only in a straight line and therefore no Pivoting of the hydraulic cylinder 7 about its lower end relative to the press housing 2 is required.
  • the bale 100 is created, the sliding door 5 is opened and the bale 100 is ejected analogously to a known box baler, as shown in Figures 5 and 6 presented and previously based on the Figures 1a - 3 described.
  • the strapping wires 20 can come out of the threading grooves 12 running in the transverse direction in the front surface 5a of the sliding door 5 and preferably no material from the press box 50 into these threading grooves 12 beforehand can penetrate, according to the invention the following design of the cross section 13 of the threading grooves 12 in the sliding door 5 is selected, as based on Figures 7a , 7b shown:
  • the cross section 13 of the threading groove 12 has the necessary groove opening 13a towards the pressing chamber 50 so that the strapping wire 20 lying in the cross section 13 can come out of the threading groove 12.
