Definitions

  • the invention relates to a feed device according to the preamble of claim 1.
  • Such feed devices are known for example from DE 32 00 840 C2, DE 34 13 786 C2 or AT-PS 335 262.
  • the pressure roller is pivotally mounted on a lever and is pivotably mounted from a rest position shown in dashed lines to a working position in contact with the longitudinal wire.
  • the pressure roller is intended to ensure that the line wire of the driven roller cannot deflect and is to ensure the transmission of the required driving forces in this way.
  • Knurled driven rollers are sometimes used in order to ensure that the line wire is acted upon securely, whereby the profiling of the driven rollers improves the transmission of force from the roller to the line wire with the same pressing force.
  • the invention has for its object to improve a generic feed device in such a way that even when using longitudinal wires with a very small diameter, a safe feed of the wires is effected and at the same time protection of the wire material is ensured.
  • the invention proposes not to use a single driven roller and a counter-pressure roller, but rather two driven rollers, between which the longitudinal wire is guided and conveyed.
  • the transmission of the feed force is therefore distributed from a single roller to two rollers, so that, with the same pressure force, a considerably improved traction or power transmission takes place.
  • the wire material is not curved even with a small diameter, so that the further handling of the longitudinal wire in the lattice welding machine is simplified and a flat design of the wire mesh produced is also ensured.
  • 1 denotes a longitudinal wire which is acted upon from below by a driven roller 2.
  • a second driven roller 3 is arranged above the longitudinal wire 1.
  • Counter rollers 15 ensure that the rollers 2 and 3 do not bend under the load.
  • the second driven roller 3 does not act directly on the line wire 1 but by means of a pressure roller 4.
  • the pressure roller 4 In the position shown in FIG. 1, the pressure roller 4 is in its working position in which it is driven on the one hand by the second driven roller 3 itself and on the other hand rests on the longitudinal wire 1 and thus also drives it.
  • the lower driven roller 2 is smooth and without knurling, so that even minimal wire cross-sections of the longitudinal wires cannot lead to damage or deformation of the longitudinal wires.
  • the pressure roller 4 is smooth and without profiling.
  • the pressure roller 4 is pivotally mounted on a boom 7 by means of a small swivel arm 5 about a hinge point 6.
  • the pressure roller 4 can swing freely around the hinge point 6.
  • the boom 7 is pivotally mounted at a pivot point 8 and is acted upon at its free, that is to say movable, end by a piston-cylinder arrangement 10 which can operate hydraulically or pneumatically and is supported on an arm 11 of the welding machine.
  • the pressure roller 4 can always assume a position in which it is in contact with both the second driven roller 3 and the longitudinal wire 1, even with progressive wear of this pressure roller or with a wide variety of line wire diameters.
  • the pressure roller 4 can be moved into its rest position by retracting the piston-cylinder assembly 10, so that the free end 9 of the Auslergers 7 is moved upwards in the drawing.
  • piston-cylinder arrangement 10 is wider than the permissible grid dimension of 25 mm, two engagement points 12 are provided for the piston-cylinder arrangement 10 at the free end 9 of each arm 7, with only one such arrangement on only one on each arm attacks the two intended points of attack 12.
  • piston-cylinder arrangements 10 can therefore each be arranged offset, as can be seen from both drawings, so as to enable the desired narrow grid dimension.
  • each arm 7 is provided with two bores 14, only one of which is used as a pivot point 8.
  • the choice of the bore 14 used in each case for the pivot point 8 depends on which of the two points of attack 12 is used for the attachment of the piston-cylinder arrangement 10.
  • the geometry of the cantilever 7 and the swivel arm 5 and their arrangement in relation to the second driven roller 3 ensures that the pressure roller rests on the roller 3 with more force than on the line wire 1, that is to say that the force vectors of the pressing force have a larger vector of the pressure roller 4 to the roller 3 as to the line wire 1. This ensures that the pressure roller 4 does not work as a pure pressure roller with the possible disadvantages mentioned, but always represents a drive roller for the longitudinal wire.
