Definitions

  • the invention relates to a pellet press, according to the preamble of claim 1, as used for example for animal feed and other materials to be pressed.
  • the invention has for its object to provide a pellet press in which the Preeformen can be changed quickly, safely and with little effort. According to the invention, this is achieved by the characterizing features of claim 1.
  • a clamp fit with or without a form fit can be realized particularly easily, with sufficient force transmission between the mold carrier and the form being ensured even under the unfavorable conditions described above (temperature and dimension differences, flexing of the form and vibrations).
  • the shape is provided on at least one of its end faces with at least one undercut opening into which a rotatable locking element engages in such a way that it has a gripping surface in a position rotated by a predetermined angular amount If the undercut of the opening is detected, there is also a simple, perfect fit between the mold and the mold carrier, with dimensional changes being easily compensated for.
  • the locking elements also serve as aids when mounting the mold on the mold carrier.
  • the mold can be fastened to the mold carrier by a simple rotary movement, for example by the drive motor for the mold, the thread simultaneously serving as a retraction device for the mold against the mold carrier and centering backs up.
  • the axially and / or radially fluid-actuated locking members are arranged so as to act in a distributed manner on the circumference of the mold, which results in the required centering.
  • At least one pressure accumulator can be provided in the fluid line for the locking members, whereby an advantageous pressurization is achieved even when there is no connection to the pressure generator, e.g. a hydraulic pump or a compressor, so that a fluid supply through the rotating mold carrier is not necessary during the operation of the pellet press.
  • the pressure generator e.g. a hydraulic pump or a compressor
  • the holding device is assigned at least one fluidic actuating device with a piston-cylinder unit, by means of which a separate plunger with piston, which is arranged in a hydraulic cylinder, can be actuated, and / or it is in one Actuating direction of the fluid-actuated locking element in the other direction is acted upon by at least one, in particular mechanical spring device, for example by disc springs, preferably in the direction of the holding position.
  • a separate plunger with piston which is arranged in a hydraulic cylinder
  • the holding device is assigned at least one fluidic actuating device with a piston-cylinder unit, by means of which a separate plunger with piston, which is arranged in a hydraulic cylinder, can be actuated, and / or it is in one Actuating direction of the fluid-actuated locking element in the other direction is acted upon by at least one, in particular mechanical spring device, for example by disc springs, preferably in the direction of the holding position.
  • The, in particular mechanical, spring device also ensures the function of the pellet press
  • the outer rotational surface of the mold is designed as a cone which can be inserted into a counter cone of the mold carrier which forms the inner rotational surface, possibly as a separate ring in this.
  • the respective radially actuatable locking element is expediently designed as a membrane that can be pressed against the external rotation surface of the mold.
  • the rotatable locking member can be used to easily center the mold on the mold carrier.
  • the mold With a relative rotation of the threaded parts from 15 ° to 100 °, the mold can be mounted particularly easily and quickly on the mold carrier.
  • the thread If the thread is designed as a conical thread, the thread itself can already serve as an essentially conical fitting surface, with particularly high forces being able to be transmitted.
  • Such threads are for example Prospection and production lines in use in the petroleum industry.
  • the arrangement of the threaded segments arranged at a distance from one another makes it possible to measure their spacing in such a way that the threaded segments of the other part of the mold carrier or of the mold can be inserted axially and then rotated. With a connection of this type, particularly high forces can be transmitted between the mold and the mold carrier, a positive connection being able to be achieved by a small angular rotation.
  • the threaded ring is detachably connected to the mold or the mold carrier, the parts subject to wear can be exchanged in a simple manner. If the working direction of rotation of the mold carrier is selected in the sense of screwing in the thread, a particularly trouble-free connection between the mold and the mold carrier is possible, since loosening of the mold during its rotation is impossible.
  • a pellet press 1 In a pellet press 1 (FIG. 1), material to be processed is fed via a hopper 2 to a metering device 3, which feeds a predetermined amount of this material to a mixer 4, to which steam is simultaneously fed via a steam line 5 (FIG. 9).
  • the material mixed in this way then enters a kinked channel 6, which feeds it to a mold cover 7, from where it enters the interior of a mold 9 via scraper blades 8 and is pressed there by means of press rollers 9a through the radial bores 9b of this die.
  • the mold 9 is held in a conventional embodiment with the aid of a ring 11 fastened to a rotatable mold carrier 10 and a clamping ring 13 which can be pulled by bolts 12 in a conical seat of the ring 11.
  • the mold carrier 10 is turned by hand to insert the levers into existing holes 14 to tighten the bolts 12, which holes are accessible via a side door 15a (FIG. 9).
  • V-belt drive shown here by way of example, any other type of drive could of course also be selected.
  • the invention is based on the object of simplifying and improving the arrangement in area A of FIG. 1.
  • a plurality of cup-like centering parts 18 are provided on the press mold 9, or instead of several such cups, a U-shaped rail 18 (see FIG. 7), as can be seen in FIG. 2, is e.g. attached to form 9 by welding.
  • the mold carrier 10 has an annular recess 19 with an insert part 20 which has a similar recess 21, the rail 18 being insertable into the recess 21.
  • the rail 18 has elongated holes 22 aligned in the circumferential direction, some of which are distributed over the circumference of the rail 18.
  • the elongated holes 22 are designed such that an elongated head 23 of a bolt 24 can enter these elongated holes 22.
  • This bolt 24 is shown in section in FIG. 7. Its exact design can be seen in FIG. 6.
  • the bolt 24 has an approximately helical groove 25 with such a pitch that this "thread" is in any case not self-locking.
  • the bolt 24 is or the like by disc springs. 27 (based on Fig. 2) against the right side.
  • 26 engages a fastened to the mold carrier 10, for example a bearing sleeve 28 'penetrating, projection or pin 28.
  • a displacement of the bolt 24 in the axial direction must therefore inevitably involve a 90 ° rotation of the bolt.
  • a piston-cylinder unit 29, 30 is arranged behind the bolt 24, the piston 30 of which carries a stamp 31 at its left end. If pressure medium is now applied to the piston 30 via a line 32, this overcomes the force of the springs 27 and pushes the pin 24 to the left.
  • the bolt 24 is rotated by 90 ° due to the threaded groove 25 so that its elongated head 23 is aligned with the elongated hole 22 (FIG. 7). In this position, the mold 9 can be pulled off the bolts 24 or a new mold can be put on. As soon as a new press mold is attached, the piston 30 is relieved, whereupon the bolt 24 moves to the right under the load on the plate springs 27 (with reference to FIG.
  • the screw bolts 35 can be omitted if a recess 121 with an inclined surface 133 lying on a somewhat smaller diameter is provided, which cooperates with a corresponding inclined surface 36 of the compression mold 9.
  • the springs 27 must be designed such that the mold 9 is frictionally clamped on the inclined surface 133, a positive connection being obtained via the bolts 24 and the U-rail 18.
  • FIGS. 4 and 5 show an embodiment variant in which, instead of the bolts 35 in FIG. 2, there is a clamp fastening with the aid of a pressure medium, the compression mold 9 being pulled into the Mold carrier 10 is carried out in the same manner as in FIGS. 2 and 3.
  • At least one printing unit 37 is provided on the back of the mold carrier 10 or (in the case of several) distributed over its circumference.
  • Each of the pressure units 37 has a piston 38, the piston rod 39 of which protrudes outwards at the rear and can be actuated in an arbitrary manner, not shown, via an annular plate 40 connected to these piston rods 39.
  • the ring plate 40 could be moved to the left or right by means of screws (based on FIG. 4).
  • the piston rod 39 could also be replaced by a screw and actuated, for example, in the manner described later with reference to FIG. 16A.
  • A, preferably hydraulic, pressure medium is accommodated in a line system 41 on the left side of the piston 38.
  • This line system 41 opens out on the side of the mold 9 into a space 42 which is separated by a e.g. made of sheet metal, membrane 43 is completed. Therefore, if the piston 38 is moved to the left with reference to FIG. 4, the diaphragm 43 expands and presses against the U-shaped rail 18 on the one hand and against an annular shoulder 44 of the press mold 9 on the other hand.
  • the press mold expediently has a corresponding one Indentation (not shown) into which the membrane (or a piston) can penetrate.
  • FIG. 5 While a certain mechanical work for adjusting the ring plate 40 is still necessary in the embodiment according to FIG. 4, this work can be further simplified by the embodiment according to FIG. 5.
  • similar units 137 are provided, which, however, have the function of a pressure accumulator or buffer.
  • a line 45 can be supplied from a pressure medium supply 46 with the aid of a pump 47, which pump via a check valve 48 in the unit 137 and the pipe system 41 promotes. If, on the other hand, the membrane 43 is to be relieved, only one valve 49 in a branch line 50 needs to be opened, whereupon the pressure medium flows back into the reservoir 46.
  • the piston 138 of the unit 137 is expediently loaded by a spring 51 (it can also be a gas spring) which compensates for any pressure peaks that may occur.
  • a spring 51 it can also be a gas spring
  • pressure sensors can be connected which, for example, trigger an alarm when the value falls below a target value.
  • the bolt 24, which acts as a locking element which can be actuated in the axial direction can be modified in various ways.
  • he himself can carry the pin 28, while the groove 25, 26 in the (in the illustration of FIGS. 2 and 3 carrying the pin 28) bearing sleeve 28 'is incorporated.
  • the bolt 24 is formed in two parts, the front part 23a of reduced diameter being the piston rod of a piston which can be displaced in a cylinder 24 and acted upon fluidically.
  • the piston rod 23a can carry a guide projection corresponding to the pin 28 and can be rotated by a groove 25, 26 formed in the cylinder 24, so that no further unit 29, 30 is then required.
  • connection for the line system 45 to 50 on the pressure unit 37 or 137 may have an additional valve (not shown) in order to be able to close off the respective unit after supplying it with pressure medium, but the valves 48, 49 can also be directly on the pressure unit unit 37 and 137, respectively, so that there is a coupling connection for lines 45 and 50.
  • the check valve 48 could be provided on the pressure unit 137 and this a coupling for the optional connection of a, for example branched connection of a, for example branched, pressure line point in which the valve 49 and (for example in a parallel branch) the pump 47 are provided.
  • the mold 9 similar to the embodiment according to FIG. 3, has an inclined surface 36.
  • this inclined surface 36 on the side of the mold carrier 10 is opposite an inclined surface 133 on an insert part 120.
  • the mold carrier 10 itself could have the inclined surface 133, but the use of an insert part 120 is preferable because it is easier to replace in the event of wear and tear.
  • the insert 120 is screwed onto the mold carrier 10 with the aid of screw bolts 135. It should be noted here that these bolts 135 do not normally need to be loosened when the shape is changed.
  • the insert part 120 is also characterized in that it is equipped with a, preferably multi-start, thread 52.
  • the mold 9 carries a threaded ring 54 which is screwed onto it with the aid of screws 53.
  • the mold 9 is equipped with corresponding screw holes 55 on both end faces.
  • the press mold When changing the shape, the press mold only needs to be screwed into the thread 52 with its threaded ring 54, the inclined surfaces 36, 133 ensuring a tight fit.
  • the threaded ring 54 could possibly itself be part of the compression mold 9.
  • the two threads 52, 54 are designed to be self-locking. It should also be mentioned that the screw holes 55 are arranged approximately in the middle of the thickness of the die 9, since the stresses are lowest there during operation. In addition, the symmetrical design with screw holes 55 on both ends of the mold 9 also has the advantage that on the Ge facing away from the mold carrier 10 a reinforcement ring, which is usually attached to the front, can be screwed into the same screw holes 55.
  • the thread is expediently designed such that it is rotated in the normal direction of rotation of the mold carrier 10 in the sense of being screwed in, it may tighten too much during operation, so that the loosening of this threaded connection can be difficult.
  • Various designs for facilitating rotary fastening via threads or for loosening them with the aid of servo-actuating devices will now be discussed with reference to FIGS. 9 to 16A, i.e. So devices that allow twisting of the threaded parts to be achieved with minimal effort, even if they are seized.
  • the V-belt wheel 17 already mentioned has two conical coupling recesses 56, 57 in its interior, each of which has a coupling cone 58 or 59 opposite it. While the cone 58 is axially displaceable and rotatably connected to the motor shaft 60 of the drive motor 16, the cone 59 sits on an output shaft 61 of a reduction gear 62, which receives its drive from an auxiliary motor 63. The cone 59 is also connected to the output shaft 61 in a rotationally locking but axially displaceable manner.
  • Both cones 58, 59 are adjustable by a common actuating device 64, so that only one of the two cones 58, 59 can be coupled to the V-belt wheel 17.
  • two moving coil magnets 65, 66 can serve as the adjustment drive.
  • the reduction gear 62 With the help of the reduction gear 62, a strong reduction by at least one order of magnitude, preferably at least two, can be achieved, the speed ratio being at for example, can be around 1: 200. It would be conceivable to achieve such a speed difference with purely electrical means, for example by using additional windings, by a DC motor with appropriate control for at least two speeds or the like.
  • the interposition of a reduction gear 62 is the structurally simpler way. It would be possible per se to design the reduction gear 62 in such a way that it can optionally be driven by the drive motor motor 16, so that the auxiliary motor 63 is saved. However, this would require greater gear expenditure than could be saved, which is why the auxiliary motor 63 is preferred.
  • the thread 52, 54 (FIG. 8) is now preferably designed such that a rotation between 15 ° and 100 ° is sufficient to tighten the mold 9 on its mold carrier 10. Therefore, if the auxiliary motor 63 is switched on in order to rotate the mold carrier 10 at reduced speed, it is advantageous if an automatic shutdown takes place as soon as the mold 9 is fastened to the mold carrier 10. In the circuit according to FIG. 9, this is solved in different ways.
  • One possibility is to provide a light source 67 for illuminating the outer circumference of the mold carrier 10.
  • the arrangement is such that the light beam strikes the area in which the holes 14 are provided, which then simultaneously serve as markings. It goes without saying that any other marking can of course also be provided. If the light beam now falls on the outer circumference of the mold carrier 10, it is reflected against a photocell 68. On the other hand, if there is a hole 14, there will be no reflection. This means that the output signal of the photocell 68 is interrupted at each hole 14.
  • a pulley 69 is pivotally mounted about an axis 70 and, for mounting the press mold 9, supports the same on a hook 71 at the correct height.
  • the mold carrier 10 is now set such that the light beam from the light source 67 is directed straight toward a hole 14, the auxiliary motor 63 cannot be excited even when a selector switch 72 is moved from the position shown in broken lines to the position shown in full lines is set.
  • This selector switch 72 is in the circuit of a pulse shaper stage 73 to which a feed stage 74 is connected.
  • the auxiliary motor 63 is not only supplied with current via the feed stage 74, but the direction of rotation can also be selected with the aid of a switch 75.
  • the line coming from the pulse shaping stage 73 forms the control line for the feed stage 74.
  • the reversing device 74 can also be purely mechanical, i.e. be designed as a reverse gear.
  • a switch S1 As a result of which the photocell 68 is bridged until it again receives reflected light from the outer surface of the mold carrier 10.
  • the time constant of the pulse shaper 73 is dimensioned accordingly.
  • the moving coil magnets 65, 66 are excited to such an extent that the coupling cone 59 enters the coupling recesses 57 the clutch cone 58 disengages.
  • An interrupter 76 may be provided so that the magnet 65 cannot be energized by mistake. This interrupter 76 is parallel to a control line for controlling a stage 174 similar to the feed stage 74 for the drive motor 16.
  • the selector switch 72 can also be connected to a terminal 77, which is located at the output of a counter Z.
  • the control is time-dependent, i.e. as soon as the counter Z has received a predetermined number of pulses from a pulse generator 78, a switch-off signal occurs via the pulse shaping stage 73.
  • the operation of the auxiliary motor 63 is either interrupted if a positioning error occurs, or if the mold 9 is screwed tightly to the mold carrier 10, in which case the mold 9 is also located gives a torque.
  • the selector switch 72 must be set to the terminal 82, which is decoupled from the terminal 81 via a valve circuit (diode D), so that the photocell at the terminal 81 is ineffective. Since the terminal 82 is controlled via a gate circuit 83, the auxiliary motor 63 can only run if the photocell 68 emits a signal and the strain gauge 79 remains fault-free.
  • a simplified circuit could also be designed such that the auxiliary motor 63 is only switched on and off manually by means of the pushbutton switch S1. In this case, the further parts 67 to 73 of the circuit shown in FIG. 9 are unnecessary.
  • the circuit is designed, it is preferable to provide a corresponding device Z, 68 or 79 by which the end of the screwing process is indicated. It goes without saying that the direction of rotation of the auxiliary motor 63 is reversed by switching the lever 75, so that in this way the mold 9 can also be released from the mold carrier 10 with the aid of the motor force.
  • FIGS. 10 to 12 come into question.
  • an insert ring 220 which supports the inclined surface 133, but a threaded ring 152 separate from this insert ring 220 is arranged.
  • the threaded ring 152 has on its outside a toothed ring, into which a pinion 84 engages and can be driven by means of a socket wrench to release the threaded connection on the back of the mold carrier 10.
  • the solution according to FIG. 11 is similar, but the threaded ring 252 has on its outside a worm toothing in which a worm 85 engages approximately tangentially and has a connection for a socket wrench 10 on the outside of the mold carrier 10.
  • FIG. 12 is even simpler, in which an external threaded ring 352 has a notch recess 86 on its radially outer side.
  • a screw bolt 87 which is inserted approximately tangentially on the outer circumference of the mold carrier 10 and protrudes into this notch recess, the threaded ring 352 being rotated counterclockwise when it rotates within a recess 88. In this way, an excessively tight thread can be easily loosened.
  • FIG. 13 shows a pellet press in a view from the front, wherein the mold carrier 10 has threaded segments 89 located at an angular distance from one another.
  • the mold 9, on the other hand, preferably has an uninterrupted threaded ring, although the reverse arrangement (mold with thread segments and mold carrier with full thread) or an arrangement in which the mold 9 also has thread segments would also be conceivable, so that the mold is not screwed into the mold carrier must, but only inserted with offset thread segments and then rotated approximately by the radian measure of the thread segments.
  • Such closures are known, for example, from artillery and have proven themselves there in view of their particularly high robustness and durability. In any case, temperature and vibration loads also occur with artillery breeches.
  • the compression mold 9 has a threaded ring 54 which is expediently connected to the same via screws 53, although it could also be designed in one piece.
  • the mold carrier 10 has, for example, a ring 90 which is provided with the threaded segments 89 inserted in the recesses. If necessary, the ring 90 can also be made in several parts be formed, both in the circumferential direction - with non-threaded sections 90b being provided between the threaded segments 89 - and in the axial direction, with an outer part 90a having a conical fitting surface which cooperates with the conical fitting surface of the die 9. Therefore, the sections 90b can be fastened with separate screws 98 (FIG. 14), the thread segments 89 (FIG. 15) with screws 91, as will be explained below.
  • FIG. 15 shows the section through a section of the multi-part threaded ring 90 with a threaded segment 89, the threaded segment 89 being held in place by means of screw bolts 91, a sleeve 91a and disk springs 93.
  • the plate springs permit an elastic displacement of the threaded segment 89 parallel to the axis of the mold carrier 10 if they are either fluidically loaded by means of a cylinder-piston unit 95 (FIG. 16) with the aid of a pusher 94 or by means of a rotary spindle 96 which will be described in detail later (Fig. 16A).
  • the plate springs 93 do not necessarily have to be arranged on the outside of the mold carrier 10, as shown in FIG. 15, but can also be arranged in the mold carrier 10 according to FIG. 15a and provide a direct cushioning of the threaded segment 89, but act in the case 15 shows the springs 93 in the sense of positioning against the cylinder-piston unit 95, in the case of FIG. 15A in the sense of loosening.
  • the cylinder-piston unit 95 shown in FIG. 16 and arranged between two plate spring assemblies 93 according to FIG. 13 is expediently of a similar design, as illustrated in FIG. 5. Above all, it will expediently not be constantly connected to a pressure source, but will only be connected to such a pressure source when the mold carrier 10 is at a standstill to release the mold 9.
  • the threaded segment 89 is moved via pushers 94 in a manner similar to that according to FIG. 16.
  • a single rotary spindle 56 shown or a cylinder-piston unit 95 can suffice.
  • a plurality of rotating spindles 96 are distributed over the circumference of the mold carrier 10, these can be actuated jointly by a chain 97 and chain wheels 99.
  • a plurality of cylinder-piston units 95 can also be connected to one another via fluid lines.
  • the axially elastic fastening of the thread or the thread segments 89 to the mold carrier 10 can also be realized without the devices 95 or 96, in which case the pusher 94 is closed, for example, by hand, for example by means of a corresponding tool is actuated (see FIG. 15A).
  • the pusher 94 is closed, for example, by hand, for example by means of a corresponding tool is actuated (see FIG. 15A).
  • an analogous effect could be achieved by an elastic fastening of the threaded ring 54 to the die 9, but the elastic displacement in the axial direction will usually be more difficult to achieve there, which is why the elastic fastening of the thread on the support side alone is preferred.
