Definitions

  • the conveying devices arranged in the outlet of extrusion presses have the task the extruded strands in the pressing direction, i.e. Discharge direction along and then convey them in their entire length or in sections transversely to the Give strands or strand sections time to cool and if necessary a stretching bench and facilities for other post-treatment, for Allocate to commercial lengths and stackers. It is too ensure that the strand ends under slight tension, so that the strand is straight is kept stretched, which is why the longitudinal conveyor in the outlet at a conveying speed is operated, which is slightly larger than the pressing speed. This initially eliminates the need for special pull-out devices consisting of a carriage that can be moved along the outlet with grippers for the strand. Of the The structural effort of these pull-out devices cannot be compensated for by a less expensive training of the longitudinal conveyor, but it results in Need to coordinate longitudinal conveyor and pull-out device.
  • Plate conveyors (DE-B2 13 00 898, DE-C2 25 56 894) are used as longitudinal conveyors, Beam straps (DE-C2 39 36 177) or belt straps used when the material to be pressed to protect the surface, do not push it sideways onto the cross conveyor, but instead to be removed, require a corresponding design by Belt deflections on the model of US Pat. No. 1,980,261, but preferably in the Form that individual belts one behind the other in a the distance of the cross conveyor appropriate length (DE-C2 39 36 177) can be used.
  • the object of the invention is to simplify the construction with appropriate Achieve cost reduction and increased service life of the longitudinal conveyor belts.
  • This problem is solved in that the longitudinal conveyor than by two Toothed drum guided toothed belts are formed, which - as with belt straps known - on the outside with a heat-resistant, the surface of the pressed material gentle fiber fleece pad and between the toothed drums by Slideways are supported.
  • the positive connection between the toothed drums and Toothed belt results in a slip-free regardless of the tension of the toothed belt Power transmission for which only one drive, namely the one pulling the upper run Dental drum is sufficient.
  • the second toothed drum, which is not driven, is only for Setting the center distance of the toothed drums, but not for the tension of the Timing belt adjustable.
  • the timing belts are covered by steel strands or Glass fiber strands of great length constancy and highly resilient.
  • Fig. 1 The entire system shown in Fig. 1 consists of an extrusion press 1 in the Spout a longitudinal conveyor 2 is arranged in the conveyor elements of a cross conveyor 3 intervene.
  • the cross conveyor 3 takes over from the longitudinal conveyor 2 from the Extruder 1 pulled strands or sections of these strands through vertical relative movement of the longitudinal conveyor 2 and cross conveyor 3. During the The strands or rod sections find sufficient time at the transverse conveying cooling already beginning on the longitudinal conveyor 2.
  • Integrated in the Cross conveyor 3 is a stretching bench 4 for stretching according to the embodiment of the strands or strand sections. From the cross conveyor 3, the strands or strand sections to another longitudinal conveyor 5, which they in Groups collected a saw or scissors 5 fed the strands in Distributes trading lengths and feeds a stacking device 7.
  • the longitudinal conveyor 2 consists of a plurality cooperating single conveyor 12, each of which has a length that fills the gap closes between two adjacent conveyor elements 13 to the cross conveyor 3.
  • everyone Single conveyor 12 consists of a frame 14 in which two toothed drums 15 and 16 are mounted, of which the toothed drum 15 via a bevel gear drive 17, 18th is driven by a shaft 19 while the toothed drum 16 is at a distance from it Toothed drum 15 is adjustable.
  • the shafts 19 mounted in the frame 14 are interconnected by couplings 20 and by one, not shown Motor driven.
  • a toothed belt 21 is guided around the toothed drums 15/16 of each frame 14, which is driven by the toothed drum 15.
  • the toothed belt 21 consists of abrasion-resistant plastic, for example polyurethane and is reinforced with tensile strands 22 made of steel strands or fiberglass strands that the Give timing belt 21 a large length constancy.
  • the outside or top is the Toothed belt 21 is provided with a non-woven pad 23, which is made of heat-resistant Fiber material. for example M-aramid fibers (heat resistance up to 550 ° C) exists and is glued to the toothed belt 21.
  • the non-woven pad 23 protects the toothed belt 21 from excessive heating and the surface of the material to be pressed from damage.
  • the side walls of the frame 14 carry slideways 24 of which the upper dreams the toothed belt 21 are supported between en toothed drums 15 and 16.
  • the abrasion-resistant toothed belts 21 slide on the slideways 24.
  • the conveyor elements 13 of the cross conveyor 3 protrude between the individual conveyors 12, so that by vertical relative movement between the conveyor elements 13 and to the individual conveyors 12, the strands that have run onto the individual conveyors 12 or Strand sections from the conveyor elements 13 for transverse transport on the Cross conveyor 3 can be taken over.
  • On the foundation 27 are Columns 28 attached to the or the base frame 25 in the vertical direction lead flexibly.
  • a base frame 25 is supported by toggle levers 29, whose one lever part 29a is variable in length for aligning the base frame 25 and for setting the formed by the upper edges of the toothed belt 21 Conveying plane of the longitudinal conveyor 2 to the conveying plane of the conveying elements 13 of the Cross conveyor 3.
  • the other lever part 29b is connected to a lever 30.
  • Die Levers 30 are connected to one another via a linkage 31 and via a further linkage 32 connected to an eccentric 33 of a drive 34. By moving the Linkage 31 in the direction of arrow 5 lowers the base frame 25 so that it on the toothed belt 21 strands or strand sections of the Conveying elements 13 are taken over and transversely conveyed.
