Definitions

  • the invention relates to a machine for producing welded wire grids from perpendicular and intersecting longitudinal and transverse wires with a multi-point welding device and with a device for moving the wire grid step by step according to the cross-wire distance by means of the longitudinal wires between them clamping, rotating in opposite directions, corresponding to the cross-wire distance intermittently drivable transport rollers.
  • a device according to the preamble of the claim is described in US-PS 36 51 834.
  • transport rollers are provided, which are designed as pull rollers and must therefore be arranged on the side of the machine on which the fabricated network, consisting of longitudinal wires and cross wires, leaves the welding device.
  • This inevitably means that the transport rollers have to roll over the cross bars and are moved up and down by the cross bars, so that the transport rollers "plan" over the cross wires.
  • the transport rollers are not only difficult to control with regard to their drive, but vibrations and different forces occur here in such a way that an exact advance of the grid is no longer possible, in particular different cross-wire diameters, which can be caused for manufacturing reasons, further increase this difficulty .
  • the transport rollers in the known device are cyclically moved via a coupling device, but it is not clear from this prior, in which form the rolls account for the different heights' distinction bill.
  • the invention has for its object to improve the generic machine in such a way that the transport rollers are easier to arrange and at the same time the supply of the longitudinal wires can be controlled more reliably with respect to the supply increment.
  • This object on which the invention is based is achieved in that the transport rollers, viewed in the direction of advance of the longitudinal wires, are arranged in front of the welding device.
  • the drive, the storage and the control of the drive steps are simple to design, since the transport rollers only have to be adjusted to the diameter of the longitudinal wires and are not subject to any vibrations and transverse movements, so that a step-over can be created which is beyond the usual Micro-processor controlled, simple design.
  • the measuring devices controlling the longitudinal feed are also easy to design, since no transverse movements are carried out by the transport rollers.
  • the invention is also based on the object of the interacting transport members To improve that a better contact force is achieved for the line wire, different parts of the grid can be taken into account more easily, without it being necessary to make major mechanical changes to the machine.
  • a pressure roller which is individually arranged on a swivel lever, the other end of which can be pressurized, for example, by means of a pneumatic arrangement.
  • This pressure roller can be easily lifted and lifted, the pressure can be adjusted as required for each pressure roller, so that, for example, different wire thicknesses can be taken into account across the width of the grid, and the pressure roller can be easily adjusted transversely to the longitudinal wire direction in cooperation with the drive roller. in order to be able to take different grid divisions into account.
  • Fig. 1 denotes a multi-point welding device known per se.
  • the longitudinal wires bear the reference symbol 2, while the transverse wires bear the reference symbol 3 and are placed on the longitudinal wires in the area of the welding device 1 and are welded to them here.
  • the longitudinal wires 2 are advanced over two longitudinal wires between jammed transport rollers 4 and 5, which are driven step by step via a drive 6, the drive being adjustable as required via corresponding program circuits. In this way, the most varied grid spacings can be set and varied as desired without mechanical changes.
  • the transport rollers 4 and 5 can be adjusted to adapt the clamping gap to the different wire thicknesses of the longitudinal wires 2, so that the different wire thicknesses can be taken into account.
  • 1 designates a welding device which is of a known type and ensures that the longitudinal wires 2 supplied to the welding device are welded with cross wires 3 placed on them, the supply of the cross wires not being shown in the drawing for reasons of clarity is.
  • the longitudinal wires are fed via so-called longitudinal wire guide nozzles 14 and 15 and via a feed device which is arranged in the feed direction of the longitudinal wires in front of the welding device.
  • This feed device consists of a drive roller 16 and a pressure roller 17, the drive rollers all moving together in a fixed position on a drive roller 18 are ordered. This ensures uniform drive of all rollers 16 by a single drive.
  • the drive with a clutch for the drive shaft 18 is shown at 19.
  • the pressure roller 17 is individually suspended for itself and is not driven, but is designed as a free-running roller.
  • the suspension takes place via a swivel lever 110, which ends, for example, in the area of the pressure roller in a fork piece 111.
  • the pivot lever 110 is pivotally mounted at 112, while a control device 114, which is formed, for example, by a pneumatic cylinder, acts on the end of the pivot lever 110 facing away from the pressure roller 17.
  • any desired contact pressure of the contact roller 17 can be set and the contact roller can be lifted off the line wire, whereby the design of the actuating device 114 as pneumatic cylinder achieves a spring effect, so that the contact roller can yield, for example, thickenings in the line wire without difficulty.
  • Each pressure roller 17 is equipped with a guide groove 115, which is chosen so large that, for example, two longitudinal wires can also be accommodated in it, so that the usual feeding of two closely lying longitudinal wires in the edge region of the grid is also ensured by a single pressure roller .
  • the training according to the invention has the further advantage; that, for example, if stronger longitudinal wires are provided in the middle of the wire mesh than in the edge area, these can be guided properly by the pressure roller in cooperation with the drive roller 16 without having to change the dimensions machine is required.
  • a gear connection between the drive of the drive shaft 18 and a gripper device 117 is shown at 116, this gear connection being able to take place via a gear chain.
  • the gripper device itself is shown as a rotating gripper chain which is equipped with a driver clamp 118.
  • the driver clamp is clamped to the welded wire mesh behind the welding device 1 and now ensures the remaining advance of the wire mesh, so that the remaining lengths of the line wires, which of the actual feeder can no longer be fed, can be welded properly at the same cross-wire spacing.
  • the drive 19 with a switching clutch for the drive shaft 18 is preferably carried out via an electrohydraulic rotary amplifier, the device for carrying out the step switching as electronic components being generally known today.
