Definitions

  • the invention relates to a winding device for wire, in particular for drawn automatic welding wire with more than two coils arranged side by side on a drive shaft and with a wire guide device which can be displaced parallel to the coil axis and through which the wire to be wound can be moved back and forth in the area of a coil and then by one Coil is moved to the neighboring coil, a measuring device for the amount of wire to be wound is provided in order to reduce the coil drive when the desired amount is reached and to start a servomotor for the step feed of the guide device.
  • a winding device As the last station of a wire drawing system, the continuously drawn wire running directly from the last drawing drum into the winding device.
  • Small coils such as sales coils, are provided as wire coils, each of which can only take up a small amount of the drawn material, but have the advantage over large machine coils, which can hold between 300 and 100 kg, that you can do your own rewinding from the machine large coils to sales coils saved.
  • wire or sales spool At high processing speeds or with a low capacity of a wire or sales spool, it is fully wound in a few minutes and must then be replaced immediately with an empty one in a winding device of the known type with only two coaxially arranged wire spools.
  • This disadvantage also occurs when rewinding the wire from large machine spools to sales spools. It is therefore necessary to use your own operator when winding smaller spools, such as sales spools. Although this can basically operate several winding machines, operating multiple machines requires very quick work, since the storage capacity of the last drawing drum is limited and it can happen that two or more bobbins become full at the same time.
  • an automatic winding device which has the features mentioned above, but in which a measuring and programming device which is completely different from the subject of the application is used and the back and forth movement of the thread guide is realized via couplings whose heavy parts are driven in opposite directions.
  • the measuring device does not measure the length of the thread directly but the number of control commands for the clutches that act on an electronic control unit.
  • the object of the invention is to trigger a length measuring device designed as a measuring roller, both a reduction in the spool speed and the control of the servomotor in a suitable time slot sequence in a simple manner.
  • a measuring roller driven by the wire is used as the measuring device, which acts on two different meter counters that can be preset on different wire quantities, the first of which causes the coil speed to be reduced and the second one to control the servomotor.
  • the speed of the shaft pivoted into the winding position can be automatically reduced, whereupon the servomotor, likewise automatically, initiates a feed step of the guide device and then the speed of the shaft is increased again to the original speed.
  • the purpose of this is to prevent the formation of loops or loops of the wire conveyed to the winding device at high speed when the winding sidewalls jump over when the guide device is fed from an already full to an empty wire spool.
  • the extent of the speed reduction of the shaft is primarily dependent on the wire material, the wire diameter and the drawing speed of the wire.
  • a proximity switch and sheet metal disks cooperating therewith, each inserted between adjacent wire coils, are provided.
  • the sheet metal disks are provided in a manner known per se with driver lugs for securely catching and holding the wire when it is being passed onto the spool core of an adjacent empty spool.
  • a preferred embodiment of the winding device according to the invention is characterized in that two drive shafts are provided which are arranged eccentrically with one end on a disc rotatable about a horizontal axis and with cantilever at its other end and that the freely cantilevered end of the shaft brought into the winding position in each case can be supported by means of a quill which can be cantilevered with the cantilevered end of the shaft.
  • FIG. 1 shows a plan view of the winding device
  • FIG. 2 shows a side view with a pulling station arranged in front of the winding device
  • FIG. 3 shows a detail of FIG. 1 on an enlarged scale
  • Fig. 4 also shows a sheet metal disc arranged between the coils on a larger scale.
  • a vertically arranged disc 3 is rotatably mounted about a horizontal axis 4, a motor 5 serving for rotation.
  • a motor 5 serving for rotation.
  • two diametrically opposed shafts 7, 8, which are arranged at a distance 6 from an axis 4 of the disk, are rotatably mounted on the disk.
  • These shafts serve to receive wire spools 9 made of plastic.
  • the wire spools are arranged on each of the shafts 7, 8 in a rotationally fixed but axially displaceable manner. The ends 10 of the two shafts 7, 8 project freely.
  • a column 12 carrying an axially displaceable quill 11 is arranged on the machine frame 2.
  • the sleeve 11 can be brought into engagement with the freely projecting end 10 of each of the shafts 7, 8 by means of a compressed air drive 13.
  • This one shaft which is designated by 7 in FIG. 1, is connected at its other end 14 by means of a coupling 15 to a shaft rotary drive 16, i. H. connectable to a pulley 18 driven by an electric motor 17.
  • a shaft rotary drive 16 i. H. connectable to a pulley 18 driven by an electric motor 17.
  • a spindle 20 Arranged approximately parallel to the shaft 7 brought into the winding position is a spindle 20 which can be rotated by a servomotor 19 and which serves for the gradual displacement of a guide device - which is designated overall by 21 - for the wire 22.
  • the guide device comprises a primary slide 23 which is mounted on guides 24. On the primary slide 23, a tension nut 25, which is penetrated by the spindle, is also arranged. Further guides 26 for a secondary slide 27 are arranged on the primary slide 23 and extend parallel to the guides 24 of the primary slide 23.
  • the secondary carriage 27 has projecting arms 28 which carry a wire guide wheel and two roller-shaped wire guide finders 30, between which the wire 22 to be wound comes to rest.
  • the wire guide fingers 30 lie directly in front of the coils 9 of the shaft 7 pivoted into the winding position.
  • the secondary slide 27 can be set into an oscillating movement by means of a hydraulic cylinder 31, the stroke of the oscillating movement corresponding approximately to the length 32 of a wire coil 9.
  • the wire guide roller 29 drives via a belt drive 33 two meter counters 34, 35, one of which 34 is coupled with a speed control device (not shown) for the shaft rotary drive 16 and the other 35 is coupled to the servomotor 19 for advancing the guide device 21 via electrical contactors, whereby the contactors function when values that can be preset on the meter counters are reached.
  • a cantilever arm 36 is attached to the primary slide 23 and extends close to the wire spools 9 of the shaft 7 pivoted in the winding position, at the end of which a proximity switch 37 responsive to metal is mounted.
  • the winding device is arranged directly after the last drawing station 38 of the production system.
  • the wire 22 is fed via a drawing drum 40 to a non-driven storage drum 41, which can be braked by means of a shoe brake 42.
  • the wire 22 runs from the storage drum 41 via the wire guide roller 29 and the wire guide fingers 30 to the shaft 7 pivoted in the winding position.
  • the wire 22 lies over the edges of the disks 45 delimiting the wire spools and is caught by one of the driver lugs 46, which are provided on each sheet metal disk 43 and which protrude radially beyond the edges 44 of the wire reel disks 45, and from slipping prevented.
  • the counters of the meter counters 34, 35 are automatically reset to zero and the speed of the shaft 7 is automatically increased again to the maximum achievable.
  • the storage drum 41 is braked by the shoe brake 42 during the speed reduction of the shaft 7 in order to keep the wire 22 in tension.
  • the drawing process continues at an undiminished speed.
  • the wire is therefore stored on the storage drum 41.
  • Contact fingers 47 which sense the amount of wire stored on the storage drum due to the height 48 of the wire turns wound on the storage drum due to the height 48 of the wire turns on the storage drum 41, control the maximum winding speed.
  • the winding device is stopped, the wire 22 is pinched off and the disk 3 is pivoted through 180 degrees after the sleeve 11 has been withdrawn and the clutch 15 released, so that in the meantime the empty wire spools 9 provided shaft 8 reaches the winding position.
  • the guide device 21 has been moved back into the starting position (near the disk 3)
  • the wire is fastened again to the first wire spool 9, the sleeve 11 is brought into engagement with the shaft 8 and the clutch 15 is engaged.
  • the drawing process also continues at an undiminished speed; the wire is taken up by the storage drum 41.
  • More than two shafts can be provided and the shafts can also be arranged on swivel arms instead of on the disk 3; the waves can also be pivoted about a vertical axis.
  • the sleeve 11 at the freely projecting end of the shaft pivoted into the winding position is not absolutely necessary; it can be omitted in the case of particularly small wire coils 9.
  • the winding device can be operated by the wire puller, who primarily only has to carry out monitoring work on the wire drawing system. His work on the winding device essentially involves placing empty bobbins, removing and possibly packing the full bobbins and placing them on a pallet. The time intervals after which this work is to be carried out depend primarily (in addition to the drawing speed) on the number of wire spools 9 arranged on the shafts 7, 8, that is to say on the length of the shafts 7, 8. For winding automatic welding wire it has proven advantageous in practice to dimension the length of the shafts so that each shaft can hold about eight to twelve sales wire spools.
  • the advantages of the winding device are particularly effective in direct winding away from the wire production system.
  • the winding device can also be used for rewinding, since there are advantages due to the longer operating cycle times, particularly when operating multiple machines.
