Definitions

  • the invention relates to an unwinder for bend-sensitive profile material, in particular metal wire, which is drawn off with a low tensile force by a machine processing the material.
  • this unwinding device is to be used for metal wire with a round or polygonal profile, which is machined in the processing machine and cut to short lengths, for example for the production of sockets, contact pins and the like.
  • Such an unwinder consists of a reel with the profile material, which is rotatably arranged with a horizontally arranged axis of rotation at a greater distance, at least ten reel diameters, from the processing machine.
  • the profile material runs off the reel and is gradually stretched by the train.
  • the processing machine exerts a certain tensile force on the profile material, but this is not sufficient to turn the heavy reel.
  • One is therefore forced to make the reel its own electromo assign toric drive.
  • the running speed of the profile material from the reel must then be adapted exactly to the feeding speed of the processing machine. This adjustment is only possible with relatively complicated controllers. Nevertheless, in practice it is inevitable that the running speed of the profile material from the reel is subject to short-term fluctuations, which act as corresponding fluctuations in the tensile stress in the profile material. This not only disrupts the uniform processing of the profile material in the subsequent machine, but it can also result in kinks due to irregular stretching of the profile material.
  • the invention has for its object to further develop an unwinding device of the aforementioned type so that the transport of the profile material takes place at a constant speed and the tensile force exerted by the processing machine is not subject to fluctuations.
  • the swivel arm and the deflection roller are very easy to form.
  • the swivel bearing for the swivel arm can also be designed to be practically frictionless. It is consequently only a very low tension in the profile material required for lifting the deflection roller with swivel arm, against the gravity acting on these parts, which can be applied without difficulty by the usual processing machines.
  • the deflection roller with its swivel arm slowly and evenly swung upwards, releasing the required length of the profile material when the reel is at a standstill.
  • the responsive limit switch switches on the drive for the reel.
  • This drive is of course dimensioned so that there is a greater peripheral speed on the reel than the retraction speed required by the processing machine.
  • the material is ultimately fed to the processing machine via a loop of variable length.
  • the reel can be stored in different ways. However, storage by two support rollers is preferably provided, which are spaced apart and are mounted parallel to each other with horizontally arranged central axes in a base plate.
  • the one of the two support rollers is preferably driven and transmits the drive movement or the driving torque to the circumference of the reel.
  • the swivel arm carrying the deflection roller is preferably pivotally mounted in the base plate, on the side of the base plate facing away from the processing machine.
  • the limit switch can be arranged at any point so that it is operated either by the swivel arm or by the guide roller. In this case, you generally need a two-part limit switch, i.e. a switch in the upper and one in the lower limit position.
  • a single limit switch with two limit positions is arranged in the swivel bearing of the swivel arm.
  • the effective diameter of the deflection roller be between half and one and a half times the diameter of the reel.
  • the reel 1 rests on two support rollers 2 and 3, which, as indicated in the drawing, are arranged and mounted above a base plate 4.
  • One of the two support rollers can be driven by an electric motor (not shown).
  • a pivot arm 7 is pivotally mounted at 8 and carries a deflecting roller 6 at its other end in a freely rotatable manner.
  • the profile material 5 runs from the reel 1 below and is looped back over the circumference of the deflection roller 6 and in the direction of arrow 9 to the processing machine (not shown).
  • the pivot arm 7, which is pivotably mounted in the bearing 8 and carries the deflection roller 6, can be pivoted upwards or downwards in the direction of the arrow 10. The distance of the axis of rotation of the deflection roller 6 from the reel and above all from the processing machine (not shown) is reduced, so that the loop in the profile material becomes shorter overall.
  • the upper limit position of the swivel arm 7 - and the deflection roller 6 - are shown in broken lines in FIG. 1 and in solid lines in FIG. 2, while in FIG. 2 the lower limit positions 6, 7 of the parts mentioned are shown in broken lines.
  • the profile material 5 is guided in a gentle, elongated arc from the reel to the deflection roller and from there again to the left, in the direction of arrow 9, without abrupt changes in the curvature.
  • the limit switch (not shown) arranged in the pivot bearing 8 of the pivot arm 7 switches the drive for the reel on in the upper limit position shown in FIG. 2 and off again in the lower limit position.
