Definitions

  • the invention relates to a device for releasable non-positive coupling of a spool, sleeve, disc, roller, wheel or the like. To a shaft, in particular of winding machines.
  • a disadvantage of the pneumatic clamping device is that it is both very expensive to manufacture and very susceptible to continuous operation.
  • the use of only friction-enhancing agents does not result in a secure, non-positive connection.
  • the object of the invention is to provide a solution with which, while maintaining the advantages of known clamping devices an inexpensive way to create a permanent solution, especially for winding machines.
  • the shaft is hollow at least in some areas and at least one clamping piece which can be moved out of the shaft cavity via the outer shaft contour is provided.
  • Such a device according to the invention can be used both in generally used winding machines and for winding machines with automatic bobbin changing as well as in other machines in which bobbins, sleeves, disks, rollers, wheels or the like are to be picked up and taken along by a rotatable shaft .
  • the change can take place while the shaft is rotating. It is not necessary to stop the shaft or the entire machine.
  • the shaft is hollow in some areas and has at least one clamping piece which can be moved out of the shaft cavity via the outer shaft contour.
  • the invention provides that the shaft has a bolt which can be moved in the longitudinal direction of the shaft and is tensioned against a force. This has the advantage that a tension between the shaft and the coil can be produced by the tension.
  • the bolt has a link surface on its side contacting the clamping piece; The same applies in the embodiment for the clamping piece itself. This has the further advantage of simple, secure clamping between the shaft and the coil.
  • the pin is designed as a pneumatic piston.
  • the bolt is clamped against an air pressure cushion in the correspondingly sealed shaft.
  • Such an air pressure cushion is easily adjustable and offers the advantage of a gentle release.
  • the surface area of the clamping piece in contact with the coil or the like has a friction-increasing surface, which leads to an improved non-positive coupling of the shaft and the coil element with a simultaneous friction-increasing surface of the coil bore.
  • the clamping force formed against the bolt can be changed, for which purpose the invention provides adjusting elements for changing the spring force, the air pressure, etc.
  • the tip of the clamping piece has a chamfer engaging in the outer shaft contour and / or that the clamping piece has effective locking lugs in the shaft cavity.
  • the chamfer makes it easier to lower the clamping piece when the bolt is pressed in.
  • the locking lugs have the effect that the clamping piece cannot fall out of the partially hollow shaft even if no coil element or the like is pushed on.
  • the device generally designated 1 has an at least partially hollow shaft 2, in the shaft cavity of which a bolt 3 which is movable in the longitudinal direction of the shaft is provided.
  • the bolt 3 is tensioned against a spring 4 inside the shaft. By pressure from the outside of the shaft onto the free end 3a of the bolt 3, the latter can be moved in the direction Y against the spring 4 up to a stop 6.
  • the bolt 3 has a groove 5 with a link surface 7, in which a clamping piece 9 lies with a corresponding mirror-inverted link surface 8. This surface 11 is flush with the outer shaft contour 10 of the shaft 2 when the bolt 3 is pressed against the spring 4 and moved in the Y direction.
  • the bolt 3 is pressed in the direction Y against the spring 4 into the shaft 2, the clamping piece 9 sinks over the against each other movable backdrop surfaces 7 and 8 until its surface 11 is again flush with the outer contour 10 of the shaft.
  • the coil element 12 or the like can be withdrawn from the shaft 2 and exchanged for another coil element 12 or the like.
  • the clamping piece 9 In order to prevent the clamping piece 9 from slipping out of the shaft cavity, the clamping piece 9 has locking lugs 13. To facilitate the sinking of the clamping piece 9 when the bolt 3 is pressed in, the clamping piece 9 is chamfered at the tip 14, so that the chamfer 14 engages in the outer shaft contour 10 of the shaft 2.
  • the clamping piece can be formed from metal or a highly slidable plastic and the like. More.
