Definitions

  • the present invention relates to a laying device according to the preamble of claim 1.
  • Such a laying device is known from DE-A 3 422 352.
  • the endless raw rubber sheet coming from a rubber cooling system is continuously or intermittently fed into the guiding device of the laying device via a conveyor device, gripped by the laying rollers and deposited on a pallet or the like by their horizontal back and forth method .
  • the raw rubber sheet As it passes through the rubber cooling system, the raw rubber sheet is cut into longitudinal strips except for a small, perforation-like layer, the width of which corresponds to the requirements of further processing.
  • the production process is hampered by the fact that stacking with the same cut edges has so far not been possible by the known laying device, so that a smooth and uninterrupted removal of the strip webs to be separated from one another after palletizing is not possible.
  • the guiding device of the known laying device serves only as an insertion aid and guiding the continuous web of material, the guiding rollers arranged transversely to the laying rollers preventing the web of material from sliding out of the guiding device laterally.
  • the material web can move back and forth within the distance between the guide rollers, so that the material web strips placed one above the other lie off-center according to their width tolerances.
  • the present invention is therefore based on the object of designing a laying device of the generic type in such a way that the material web is cut-edge-straight or centered on the pallet with the simplest design means and its subsequent removal for further processing is thus trouble-free and therefore more cost-effective.
  • This construction ensures that the center line of the web to be transported by the laying rollers is the same. Since the cutting process of the cut strips is also aligned with the middle of the web by a cutting unit in the upstream rubber cooling system, exact palletizing along the cutting edges is guaranteed.
  • the construction according to the invention offers further advantages. On the one hand, it is extremely inexpensive to manufacture, and on the other hand, its operational reliability is very high, since the central position control of the material web is carried out exclusively by mechanical parts, which in particular under the aspect of the extremely harsh operating conditions that prevail when processing rubber webs, a trouble-free operation enable.
  • the basic arrangement of the laying device shown in the figures consists of a frame 1, which is fixed with its rear vertical bar 3 to a rubber cooling system, not shown, a horizontal laying frame 10, which is guided at one end in the bars 3 and by means of a pressure cylinder 2 is adjustable in height.
  • a carriage 20 provided with castors 21 can be moved horizontally back and forth in the laying frame 10.
  • two articulated arms 31 are each pivotally fixed at one end, while their other ends are arranged on the opposite rotatable laying rollers 30, which form an active gap and can be driven.
  • At least a pair of the articulated arms 31 are connected to one another by a pressure cylinder 32, so that the laying rollers 30 change their distance from one another when the pressure cylinder 32 is actuated.
  • a centering device is provided above the laying rollers 30, with which the material web, in the present exemplary embodiment the rubber web 5, can be guided in a constant manner in its central course.
  • the centering device consists of two opposing guide rollers 40 arranged transversely to the laying rollers 30, which in the position of use are pressed onto the side edges of the rubber sheet 5 with the same pressure.
  • Each guide roller 40 is fixed to a roller carriage 43, the rollers 44 of which are guided in a holding frame 42 and which can be moved transversely to the running direction of the rubber sheet 5.
  • the holding frame 42 is fastened in the area between the laying rollers 30 and the carriage 20, so that the back and forth movement of the carriage 20 and the laying rollers 30 is also carried out by the holding frame 42.
  • the force for pressing the guide rollers 40 against the rubber web 5 is generated by a pressure cylinder 41, preferably a pneumatic cylinder, the cylinder of which is fixedly connected to the carriage 20 via a flange 46 and the piston of which is connected via a bracket 45 to a roller carriage 43.
  • a chain tensioner 50 is also arranged on the bracket 45, as is a driver 47 which is connected to the other roller carriage 43.
  • two deflection wheels 49 which are designed as chain wheels in the present exemplary embodiment, are fixed on the holding frame 42.
  • a chain 48 is guided over the deflection wheels 49 facing away from the piston of the pressure cylinder 41, one end of which is connected to the driver 47 and the other end of which is connected to the chain tensioner 50, which is fixed to the plate 45.
  • a chain 51 which is connected on the one hand to the chain tensioner 50, which is connected to the driver 47, and on the other hand is fastened to the plate 45, is guided over the opposite deflection wheels 49.
  • the lifting movements of the printing cylinder can be coupled to one another, for example, with the position of the laying rollers 30. Thereafter, when the laying rollers 30 are in a spread position, in which the rubber sheet 5 is inserted, the pressure cylinder 41 is switched so that the piston of the pressure cylinder 41 reaches an extended end position. As a result, the roller carriage 43 coupled directly to the piston also becomes an outermost position shifted, as the opposite roller carriage 43 by the chain hoist exerted, which is transmitted to the chain 48 by the chain tensioner 50 connected to the link 45.
  • the pressure cylinder 41 is provided with a quick exhaust valve which is effective when moving apart, so that the two roller carriages 43 are moved apart correspondingly quickly.
  • a stop for the guide rollers 40 when they move towards the rubber sheet 5 is formed by their respective side edges.
  • the guide rollers 40 are pressed onto the side edges at a relatively low pressure, for example 0.8 bar, in order to prevent the side edges from buckling.
  • the rubber sheet 5 is pressed into a position by the rotatably mounted return roller 40 associated with the changed run or the changed contour of the side edge, in cooperation with the opposite guide roller 40, which position corresponds exactly to the predetermined center course.
