Definitions

  • the invention relates to an unwinding device for wires of coils in the cable industry, consisting of coil holders, the tubular mandrel is penetrated by a shaft which carries at its free end a motor-driven throwing disc, each of which is arranged under a funnel through which the wire is withdrawn via idlers attached to a gallows.
  • Such an unwinding device has become known from DE-AS-1 063 235.
  • two coil holders and two funnels are provided.
  • the two funnels are connected by a narrow slot.
  • the start of the wire of one coil is inserted into this narrow slot and connected to the end of the wire of the other coil. If one spool is now unwound, in this construction the wire jumps through the slot from one funnel into the other funnel and now unwinds the wire from the second spool.
  • the spreading disc serves to facilitate the removal of the wires over the front of the coil.
  • the disadvantage of this known unwinding device is that a worker must always be available to remove the empty bobbin immediately after unwinding the one bobbin and replace it with a full one. Then the worker usually has considerable time to wait for the other spool to unwind.
  • DE-AS-1 063 235 points out that not only two coils can be unwound, but that three or even more cycles running one after the other are possible, however, they do not specify tools for this. If the work equipment used for the layered unwinding of two coils is used, then the device becomes complex due to the need to provide additional funnels and to assign an electric motor to each coil holder. Such a device would also be uncomfortable to use. Since considerable space on the loading parts is required for loading the coil holders with the new coils, this space would have to be kept free around the entire device. These are major disadvantages.
  • the invention avoids these disadvantages. It is the object of the invention to design an unwinding device for a large number of coils to be unwound cyclically one after the other with little effort so that a worker only has to come once for a longer period, often an entire working shift, to pass the empty bobbins through full bobbins to replace.
  • the invention is that a plurality of coil holders are arranged on the edge of a turntable, that outside the turntable in the circumferential area, two drive motors are provided with friction rollers for attacking a friction roller arranged on the spreading disc shaft and that the turntable with one in certain positions according to the is fixed by the arrangement of the coil holder given division holding locking device.
  • the turntable is rotated by a pitch given by the distance between two spool holders, the unwinding process being continued without interruption. Because for the wire to be unwound, there is only a shift from one half of the funnel to the other half of the funnel and the throwing disks are constantly rotated by the two motors via the friction roller drive. Only when an empty bobbin is moved away from the funnel by rotating the turntable, i.e. comes to stand outside the funnel, does the spreading disc come to rest because it is no longer driven by a motor.
  • the throwing disc of the next following spool is already driven by the second motor, so that when the unwinding process changes from the empty bobbin to the full spool, the throwing disc assigned to it already rotates at full speed.
  • a turn of the turntable to be able to automatically carry out the division given by the distance between two coil holders, it is expedient if a sensor which detects the presence of the wire and which is part of the control of a pivoting device acting on the rotary table is arranged between two coil holders.
  • the funnel has a single elongated opening, covers two throwing discs and a device is provided which raises the funnel during the pivoting of the turntable. Therefore, in the unwinding process according to the invention, the funnel is expediently axially displaceable and can be arranged in two positions.
  • each bobbin holder is pivotable about an inclined axis and can be locked in two positions, one position in which the mandrel carrying the bobbin points radially outwards and another in which the mandrel points obliquely upwards into the funnel on the extension of the axis of the turntable.
  • the opening of the funnel facing the turntable is oval or as an elongated hole between two semicircles with straight or slightly outwardly curved edge lines between the semicircles.
  • Such a funnel is much easier to produce than funnels whose opening has a constriction in the middle.
  • a series of coil holders 2 are arranged on the turntable 1.
  • Fig. 1 only two coil holders are shown to make the drawing understandable.
  • Fig. 2 it can be seen that one coil holder is arranged next to the other.
  • Each coil holder has a swivel joint 3, with which the mandrel, as can be seen on the left in FIG. 1, can be adjusted on the one hand into a radial position for attaching the coil 4 and on the other hand in a direction pointing obliquely upward towards the extension of the axis 5 of the rotary table.
  • a throwing disc 6 is arranged in front of the end face of the coil 4 and is driven by a friction disc 7 which is arranged on the same shaft as the throwing disc 6.
  • This wave passes through the mandrel on which the coil 4 is inserted.
  • the friction disks 7 are driven by friction disks 8 from motors 9.
  • Two motors 9 of this type are provided which are in constant operation and whose friction disk 8 is pressed against the friction disk 7 by spring pressure. These motors 9 are located in the area of the funnel 10, which is arranged on a column 11 about which the turntable 1 rotates. Rotary table 1 and column 11 thus perform a rotary movement relative to one another.
  • the funnel 10 is provided with a displacement device with which it can be set in a higher and a lower position. It assumes the higher position when the turntable is rotated. It takes the lower position when the turntable 1 is fixed.
  • the lower funnel edge covers the throwing disc 6 of the spool to be unwound.
  • the core 13 is drawn off through this funnel 10.
  • the sliding roller 14 on the gallows 15 gives the wire 13 such a direction that it runs through the extension of the axis 5 of the turntable and is guided here in the extension of this axis.
  • a sensor 16 in which the end part of the wire of the previously arranged coil connected to the beginning part of the wire of the new coil is inserted.
  • an impulse is emitted which is not in the Drawing shown device for the gradual movement of the turntable in action.
  • This device rotates the turntable in each case by a division given by the spacing of the coil holder.
  • the turntable 1 In order to be able to load the coil holders from one point, it is expedient if the turntable 1, the motors 9 and the rod 11 holding the funnel 10 are arranged on a further turntable 17. The gallows 15, however, are not arranged on this rotary table 17. This rotary table 17 ensures that all coil holders 3 can be loaded from the same point on the circumference without interrupting the unwinding process.
