Definitions

  • the invention relates to a press for briquetting granular material according to the preamble of claim 1.
  • Such presses are available on the market. They are primarily used to press chip-like waste, such as those generated when machining wood and plastics, or granulate or powder-like materials into compact briquettes that are easy to handle and can be stored in a space-saving manner.
  • a press according to the preamble of claim 1 is from U.S. 3,527,160 A known.
  • a cylinder base is attached to the end of a press cylinder via two pivotable arms arranged laterally on the latter.
  • the relative movement between the cylinder base and the press cylinder takes place in that a drum, which comprises a plurality of press cylinders distributed in the circumferential direction, is rotated over a stationary plate, which also represents the cylinder bases for the various press cylinders.
  • This arrangement takes up a relatively large amount of space. A lot of material has to be used to realize it, and the press is correspondingly heavy.
  • the present invention is intended to create a briquetting press of the type described at the outset which takes up less space, can be implemented using less material and has a simple and robust structure.
  • the cylinder base only needs to have a slightly larger transverse dimension than corresponds to the clear diameter of the press cylinder.
  • the cylinder base is thus a compact and lightweight component. Due to its relatively low mass, it can be quickly moved between a working position in which it closes the side of the press cylinder remote from the press piston into an ejection position in which the end of the press cylinder remote from the press piston is open.
  • a briquette can then be ejected from the press cylinder by advancing the press piston further.
  • This type of briquette production is less advantageous for some materials because the maximum pressure that is achieved during briquetting is relatively low.
  • the individual briquettes obtained by breaking off the briquette strand do not have exactly the same axial dimensions, and the fracture surfaces which form the end faces of the briquettes are irregularly shaped.
  • all the briquettes have exactly the same external geometry.
  • the briquettes can also be pressed with very high pressure, as the press ram works against the rigidly supported cylinder base.
  • the final pressing pressure can also be set simply via the drive which works on the press piston.
  • the cylinder base is arranged on the machine frame so that it can pivot about a pivot axis is advantageous in terms of enabling the cylinder base to absorb strong forces. Strong forces can be absorbed more easily by means of a pivot bearing than by means of a sliding guide, which, by the way, can also be used to move the cylinder base.
  • the part forming the cylinder base has a great length compared to the drive lever.
  • the angle lever which is formed by the cylinder base and the drive part, thus provides a movement transmission between the drive lever and the output lever. This means that the cylinder base can be pivoted between its two positions by small drive movements.
  • the finished briquettes are delivered in a predetermined orientation. This is advantageous if you want to stack the briquettes compactly after production.
  • the finished briquettes are moved towards the briquette discharge opening at an increasing transverse distance from the press cylinder axis. This is advantageous because a rear section of a briquette protruding into an extension of the press cylinder can also be used as a driver on which an axial feed force is exerted by a subsequent briquette, which is ultimately generated by the press piston.
  • the two guide plates for the cylinder base serve at the same time as a load-bearing bearing for a bearing journal which carries the cylinder base.
  • “granular material” should be understood to mean any material which consists of individual smaller pieces which can be moved relative to one another and which are separated from one another by larger gaps in bulk. Specifically, it can be a material that is obtained when sawing or milling a material such as wood, plastic or metal. However, it can also be a material in the form of chips, such as is obtained when planing wood or turning plastic or metal. After all, it can also be small, massive pieces that are left over from sawing work or are given away by shredders.
  • 10 denotes a press cylinder as a whole. This comprises a central cylinder section 12 which is lined with a hard, wear-resistant and smooth sleeve 14.
  • the sleeve 14 delimits a pressing chamber 16.
  • the cylinder end piece 18 has a flat end face on its side located on the left in the drawing. Its in the End face 22 located on the right in the drawing is partly cylindrical.
  • a cylinder base 24 is shown, which is arranged pivotably on an axis 26.
  • the latter is firmly attached at both ends to a machine frame 28, which is only indicated schematically.
  • the cylinder base 24, like the cylinder end piece 18, has a constant cross section in the direction perpendicular to the plane of the drawing. Its in Figure 1 End surface 30 on the left is partly cylindrical, the cylinder axis coinciding with the axis of axis 26.
  • the end surface 22 of the cylinder end piece 18 is complementary to the end surface 30 of the cylinder base 24; its axis also coincides with that of the axis 26.
  • a drive lever 32 is rotatably connected to the cylinder base 24. Its drive end, which is remote from the axis 26, is connected in an articulated manner to a piston rod 36 of a hydraulic working cylinder 38 via a pin 34. Its housing is supported in an articulated manner on the machine frame 28 by means of a pin 40.
  • the cylinder base 24 can be moved from the working position shown in the drawing into a clockwise release position in which the opening 20 is exposed.
  • a pressure piston 42 runs in the sleeve 14. This is placed on the end of a piston rod 44 which is part of a hydraulic working cylinder 46.
  • the press piston 42 By acting on the working cylinder 46, the press piston 42 can be moved from left to right in the drawing for pressing granular material. During this movement, granular material introduced into the press cylinder 10 is pressed against the cylinder base 24 which is in its working position.
  • the circumferential surface of the material is given a shape that is predetermined by the sleeve 14.
  • the end surfaces of the compressed material are given a geometry which corresponds to the geometry of the end surface 30 of the cylinder base 24 or the geometry of the front end surface of the plunger 42.
  • a feed unit designated as a whole by 48 is provided for feeding in granular material. This includes a feed cylinder 50, the axis of which is perpendicular to the axis of the press cylinder 10.
  • the feed cylinder 50 is inserted into the wall of the cylinder section 12 in a form-fitting manner with its end lying at the bottom in the drawing.
  • a feed piston 52 which is moved by a hydraulic working cylinder 54, can be displaced in the feed cylinder 50.
  • the plunger 52 has one in the drawing lower, front piston end piece 56, which has a cylindrical end surface 58.
  • the end surface 58 is a smooth continuation of the peripheral wall of the sleeve 14 and fits exactly into an opening 60 of the sleeve 14 provided for feeding material and an opening 62 of the peripheral wall that is aligned with the latter of the middle cylinder section 12.
  • an opening 64 is provided in the peripheral wall of the feed cylinder 50, which opening is connected to a feed channel 66 in which a feed screw 68 runs, which is rotated by a motor 70.
  • the feed piston 52 carries various axially spaced sealing rings 72 on its outer surface.
  • the working cylinder 46 working on the plunger 42 is arranged in a tubular protective housing 74, which consists of two screwed housing parts 76 and 78 and represents an extension of the press cylinder 10 and is rigidly connected to it.
  • a pressure supply unit for the working cylinder 38 is shown schematically at 80.
  • the pressure increase in the working space of the working cylinder 46 can also be monitored.
  • the pressurization of the working cylinder 46 is maintained for a predetermined period of time in order to stabilize the compression of the granular material in the press.
  • the two working spaces of the working cylinder 46 are relieved of pressure and connected to one another.
  • the press piston 42 thus no longer exerts any force on the briquette located in the press chamber 16.
  • the abutment surface between the end surface and the end surface 30 of the intermediate floor 24 is relieved of pressure, and the frictional engagement between the end of the briquette and the end surface of the intermediate floor is correspondingly reduced.
  • the intermediate floor 24 can now be pivoted with little force.
  • This pressure relief of the plunger 42 is maintained until the cylinder base 24 has reached its release position. This can be done either under time control or by monitoring the output signal of an end position sensor (not shown) which responds when the cylinder base 24 has reached its release position.
  • the pressure supply unit 76 again pressurizes the working cylinder 46 in the extension direction, so that the finished briquette is ejected from the press cylinder 10.
  • the pressure supply unit 76 then moves the working cylinder 46 back into its retracted rest position, which can be done again in a time-controlled manner or using an end position sensor.
  • the briquetting press described above works as follows: In the initial state shown in the drawing, by rotating the feed screw 68, granular material is conveyed from a storage container into the interior of the feed cylinder 50, where it falls down.
  • the feed screw 68 is stopped and, by applying pressure to the working cylinder 54, the feed piston 52 is advanced until the end surface 58 of the Piston component 56 represents a smooth, aligned addition to the circumferential surface of the sleeve 14. Reaching this end position can be ensured simply by appropriate stops which work together with the piston end piece 56 or the feed piston 52.
  • the feed piston 52 When the feed piston 52 is moved into the lower working position, the granular material which lies under the end face of the piston end piece 56 is already somewhat pre-compressed. A part of the granular material also escapes into the interior of the sleeve 14 in a lateral direction under the pressure exerted by the feed piston 52.
  • the press piston 42 After the feed piston 52 has reached its working position, the press piston 42 is moved from left to right in the drawing by applying pressure to the working cylinder 46. This movement takes place until the end face of the plunger 42 has reached a distance in front of the end face 30 of the cylinder base 24 which corresponds to the desired axial dimension of a briquette. With a view to resilience of the briquetted material after it has left the briquetting press, this desired dimension can be somewhat smaller than the dimension ultimately desired for the storage and transport of the briquettes.
  • the pressurization of the working cylinder 38 is temporarily removed in order to reduce the friction between the end face of the finished briquette on the right in the drawing and the end face 30 of the cylinder base 24.
  • the cylinder base 24 is now pivoted clockwise, whereby the opening 20 of the cylinder end piece 18 is now exposed.
  • the finished briquette is now ejected by the plunger 42.
  • the press piston 42, the feed piston 52 and the cylinder base 24 are then moved back into their starting positions shown in the drawing and the cycle described above for pressing a briquette starts again.
  • the briquetting press described above stands out in practice through good constancy of the dimensions of the briquettes produced.
  • the granular material can also be pressed into briquettes under very high pressure, since the open side of the press cylinder 12 is reliably closed by the cylinder base 24 during the pressing itself and can withstand high loads.
  • the briquetting press is also compact in most transverse directions. Only in the direction in which the feed unit 48 is attached does it have larger dimensions.
  • FIG. 14 is a perspective view of the end of a press such as that described above with reference to FIG Figure 1 was explained. Components that correspond to components already explained are again provided with the corresponding reference symbols and are not described again in detail below.
  • the press shown has a delivery unit, designated as a whole by 80, which is attached to an upstream, in Figure 2
  • the end located on the right takes over briquettes originating from the press cylinder 10 and leads them to a discharge opening 82 in a predetermined orientation. There they can be taken over by a handling device which stacks the individual briquettes in a transport container.
  • the delivery unit 80 comprises a delivery channel 84, which can be formed by a bent sheet metal part or can be located in a solid part, as shown.
  • the discharge channel 84 On the output side, the discharge channel 84 has folded flanges 86, with which it is connected to an identical cross-sectional contour having conveying pipe can be connected in that the individual briquettes are then conveyed to a packaging location under the action of gravity or compressed air or a mechanical drive.
  • braking rollers 88 are provided on both sides, which work together with two opposite main surfaces of a briquette 90, so that a briquette is only delivered when it experiences an ejecting force from behind.
  • Figure 3 shows a first possibility of how a finished briquette 90, which has been compressed between the end face of the plunger 16 and the cylinder base 24, is transferred into the discharge channel 84.
  • the cylinder base 24 is moved from the working position shown by solid lines by retracting the piston rod 36 into a rest position pivoted by 90 ° in the exemplary embodiment, which is shown in dashed lines in the drawing.
  • the press piston 16 can now push the finished briquette 90 into a transfer channel 92, which represents an extension of the press chamber 16 of the press cylinder 10.
  • the stroke of the plunger 16 is dimensioned such that at the end of the stroke the briquette 90 is moved into a transfer position shown in dashed lines, in which it lies above an opening 94 which is obtained by cutting through the delivery channel 84 with the transfer channel 92.
  • the opening 94 has at least the same axial dimension as a briquette 90.
  • the axial dimension of the opening 94 is approximately 10% greater than the length of a briquette 90.
  • the bearing journal 26 for the cylinder base 24 is oriented vertically, so that the cylinder base 24 is moved in a horizontal plane. It is guided between two guide plates 96, 98 in flat sliding contact, which in turn are screwed to the end of the cylinder end piece or the end of the press cylinder 10 via screws 100.
  • the guide plates 96, 98 each have transverse arms 100, 102 on the side facing the press cylinder 10, on which screws 104 engage, which run in the press cylinder 10 and the cylinder end piece 18, respectively.
  • the in Figure 2 Arms 102 on the right are so short that their end faces follow the side face of the press cylinder 16.
  • the delivery channel 84 now runs parallel at a distance from the channel of the press cylinder and the transfer channel 92.
  • the cylinder base 24 is now provided with a rectangular extension 118, which moves a briquette from the transfer channel 92 into the delivery channel 84 in a lateral direction.
  • the delivery channel 84 now contains a belt conveyor, denoted as a whole by 120, which is integrated into the outer side wall of the delivery channel 84.
  • this conveyor comprises a conveyor belt 124 that works frictionally with the briquettes and a pressure plate 128 which is prestressed by springs 126 in the direction of the briquettes behind the rear of the working section of the conveyor belt 124 the briquettes 90 in the delivery channel 84 are moved towards its delivery opening 82.
  • the operation of the belt conveyor 124 is electrically synchronized with the supply of a further briquette, in such a way that the section of the belt conveyor 124 located behind the transfer opening 94 is empty before a briquette is ejected.
  • the briquetting presses described above can be built from very simple and robust components.
  • the outside of the cylinder housing carries a mounting ring 130, which is provided with a stub shaft 40 on its upper side and on its lower side.
  • the two stub shafts are rotatably mounted in bearing openings of bearing brackets 132, which on the in Figure 5 front side surfaces of the guide plates 96, 98 are screwed.
