Definitions

  • the invention relates to a device for continuously withdrawing wire via a rotatable deflecting element, preferably a deflecting roller or deflecting roller, preferably each of one of at least two unwinding cells from a wire ring, which preferably rests on a holding mandrel or a holding plate.
  • a rotatable deflecting element preferably a deflecting roller or deflecting roller, preferably each of one of at least two unwinding cells from a wire ring, which preferably rests on a holding mandrel or a holding plate.
  • Such a device is used in particular in wire works in which wire e.g. Structural steel mats and the like can be manufactured continuously and in particular fully automatically.
  • the wires are usually first fed to a drawing machine after they have been pulled off, and then guided to the drain banks of the lattice welding systems.
  • a deflecting element preferably serves as an auxiliary element, a deflecting roller or deflecting roller, via or from which the wire is drawn off from said wire rings.
  • the operating personnel must therefore always provide a further reserve wire ring in addition to the wire ring that is currently in the unwinding process.
  • the operating personnel also has to weld the end of the wire ring currently in the unwinding process to the beginning of the following wire ring, so that when the first wire ring is exhausted, wire is pulled off the second wire ring without interruption.
  • the wire puller runs the risk that the wire end of the first wire ring located in the trigger will be torn from him; in this case, the wire puller can also be injured by the pulled wire end, which may quickly turn around.
  • the welding creates a free-hanging wire connection, i.e. a loop or loop, which can not only swing out uncontrollably when quickly removed, but possibly the operator, i.e. the operator Grasp the puller and pull it up
  • the two wire rings are each housed in separate or several unwinding cells, so that the operator is provided with a certain amount of security against wire wires which are being folded over; the unwinding cells are usually designed as one-sided open cages into which the wire rings are to be placed.
  • the prior art also suffers from sensitive interruptions in the further processing operation in every small or large incident, especially since a new beginning of the wire often has to be pulled over the take-off roller or take-off roller again.
  • the invention is therefore based on the object of providing a device for continuously withdrawing the type mentioned at the outset, which avoids accidents for the operating personnel and permits uninterrupted removal of the wire.
  • the wire ring rests on at least one weight-sensitive switch which interrupts further removal when the weight falls below a certain value corresponding to the wire ring residue and in that a switch is arranged outside the at least two unwinding cells, by means of which the further removal of the wire ring residue is arranged can be left switched on.
  • this device is further characterized in that the switch is a hand switch.
  • a further preferred embodiment is further characterized in that a clamp holder is arranged between the at least two unwinding cells for receiving or guiding the beginning of the wire ring of the other unwinding cell welded together with the end of the wire ring of the one unwinding cell.
  • the further pulling off would be switched off by the weight-sensitive switch on which the remainder of the wire ring still rests.
  • the operating personnel go outside the at least two unwinding cells and actuate a switch, preferably a manual switch, by which the further removal of the wire is then left switched on.
  • the wire is then continuously withdrawn from the second cell, that is to say the reserve cell in which the second wire ring is located, without any interruption in the removal process.
  • a clamp holder is arranged between the at least two unwinding cells for receiving and guiding the beginning of the wire ring of the second unwinding cell welded together with the end of the wire ring remainder of the one unwinding cell.
  • the welded wires can be inserted into this clamp holder, so that there is no longer a freely movable wire connection section, so no loop remains between the remainder of the wire ring and the second start of the reserve wire ring. This also avoids the risk of accidents because the wire puller no longer has to hold the area of the welding point by hand, ie the wire puller does not have to be at the danger point.
  • the unwinding cells are identified by the reference numerals 2 and 2 '. They are separated from one another by partitions 3, 3 'and 3 ". Above the unwinding cells 2 and 2' there is the take-off roller or take-off roller 4 rotating in the direction of rotation 5. Via this take-off element 4, the beginning 10 of the wire ring located in the unwinding cell 2 is located deducted.
  • the wire rings are located in the unwinding cells 2 and 2 'on spikes or reels 1 known per se.
  • the wire ring in the unwinding cell 2 is reduced to the wire ring residue 8.
  • This wire ring residue 8 rests on bearing tongues 12, as did the much heavier entire wire ring previously.
  • These bearing tongues 12 are pivotable in bearings 13 essentially perpendicular to gravity and thus also to the bearing plate 22.
  • the bearings 13 are arranged on the bearing plate 22 for this purpose.
  • the pivoting movement is effected by adjustable tension springs 15 which, on the one hand, engage at the ends of the tongue levers 14 under the bearing plate 22 behind the bearings 13 and, on the other hand, on the bearing plate 22 itself.
  • the tongue levers 14 are thus pressed against a touch switch 16. If the weight of the coil remainder 8 becomes too small, the bearing tongues 12 can be moved vertically and thus raised by the bearing plate 22 against the weight of the coil remainder 8. As a result, the tongue levers 14 are pressed against the touch switches 16; this has the consequence that the further pulling would be interrupted if the switch was not actuated, which is preferably a manual switch continuous switch.
  • the end 11 of the wire ring remainder 8 is in the meantime already arranged with the beginning 10 'of the following wire ring 9 in the unwinding cell 2', welded by means of a welded joint 17. In the situation shown, the wire puller therefore only has to go to the manual switch 6 on the partition 3 outside the unwinding cell 2 and to actuate the same.
  • the removal process continues via the weld connection 17 to the start of the wire ring 10 'of the following wire ring without interruption, so that the wire ring 9 is then removed from the unwinding cell 2' in the following.
  • the unwinding cell 2 is now free, so that a new wire ring can be inserted into it. Its beginning can then be welded to the end 11 'of the wire ring 9 in the unwinding cell 2' in the known manner. It can be seen that the wire ring 9 in the unwinding cell 2 'presses the bearing tongues 12 by virtue of its weight against the bearing plate 22, so that the tongue levers 14 are lifted off the touch switches 16. The touch switches 16 are therefore not actuated, so that the pulling off is not interrupted either.
  • FIG. 2 shows a particularly suitable embodiment for a clamp holder 18 for realizing the subject matter of the second patent claim.
  • This clamp holder 18 is resiliently attached to the wall strut 21 of the partition 3.
  • the clamp holder 18 is essentially formed from an elastic sheet metal strip, but that at its free end is bent into an angled clamping tongue 20, the tip of which protrudes up to the wall strut 21, so that a slot 19 is formed between the remaining sheet metal strip and the wall strut 21 . In this area, the sheet metal strip is bent away from the wall strut 21 in order to keep the slot 19 clear.
  • the start of the wire ring 10 ′ can be pressed into the slot 19 between the clamping tongue 20 and the wall strut 21, since the clamping tongue 20 can be resiliently pushed away from the wall strut 21.
  • the wire ring start 10 ' is then held in the slot 19.
  • the clamping tongue 20 can be resiliently pushed away from the coil start 10' by the wall strut 21, so that the wire results beginning of the ring 10 'can escape from the slot 19.
  • the wire ring or rings can rest on circular plates or ring-shaped plates or other analog elements which cooperate with the weight-sensitive switch.
