Definitions

  • the present invention relates to a device for controlling the feed of a feed apparatus intended for the gradual advancement of a band-shaped workpiece.
  • US Pat. No. 3,758,011 and US Pat. No. 3,784,075 each disclose a device for incrementally advancing a workpiece, in which there is a fixed relationship between the speed of the drive shaft and the phase of the oscillation. This ratio cannot be changed in the known devices, once it has been set, or only with great effort.
  • the invention seeks to remedy this.
  • the invention as characterized in the claim, achieves the object of providing a device for controlling the feed of a step-by-step feed apparatus, in which a number of control disks are arranged on a sliding sleeve, which is axially displaceable relative to the sleeve section, and a further control disk is present, which is fixedly connected to the sleeve portion.
  • Figure 1 shows an embodiment of a feed device in section.
  • FIG. 1 now shows a further embodiment of the device for switching or controlling the feed, which is generally the same as the embodiment according to FIG. 6 of the said application. Accordingly, the same reference numbers are used in the description of this embodiment and only the decisive structural differences are dealt with.
  • a sliding bushing 84 is again arranged in a rotationally fixed and axially displaceable manner.
  • This carries a number of control disks 101, 102 which correspond to the function according to the cam member 12 of FIG. 1 of the application description mentioned.
  • Another control disk 100 is fixedly connected to the bushing section 83 or is formed in one piece with the same.
  • These control discs 100, 101 and 102 control the movement of the rollers 110 and 111, which are connected via the arm 9 to the linkage for moving the rocker 4. It can be seen here that the roller 110 interacts exclusively with the control disk 100, whereas the roller 111 interacts with either the control disk 101 or the control disk 102 depending on the axial displacement position.
  • the spool 92 has a driver 93 which projects into a space between the control disks 101 and 102.
  • the sliding sleeve 84 can thus be moved back and forth on the sleeve section 83 by means of the control slide 92, and the one of the control disks 101, 102 on which the roller 111 has to rest is selected.
  • the sliding sleeve 84 also has tooth-shaped coupling elements 103 which can be brought into engagement with the tooth-shaped coupling elements 104 which are arranged on the drive shaft 11.
  • the drive shaft also has a recess 96 in the section forming the eccentric member, into which a locking member 97 which can be moved longitudinally in the housing 1 can be inserted.
  • the rocker is timed by two control disks, namely the control disks 100 and 101 or the control disks 100 and 102 by the roller 110 and 111 respectively resting thereon and correspondingly interacting components, the up and down movement of the feed roller 3.
  • the control disk 100 together with the roller 110 controls the phase of the intermediate ventilation of the holding ruler 46, during which a workpiece to be machined is not held and centered by a holding ruler but only by holding members on a tool that is machining the same.
  • the two control disks 101 and 102 which cooperate with the roller 111, determine the adjustable feed or the feed phase of the feed apparatus.
  • the epicyclic gearbox now behaves as in the corresponding position of the control slide 92, which is described with reference to FIG. 6 of the application description mentioned, with a 1: 1 transmission now taking place, that is to say that the upper feed roller 3 during 180 ° of the rotary movement of the drive shaft on the to be fed sheet metal band 43 rests. So there is again the direct drive transmission.
  • the phase position of the intermediate ventilation predetermined by the control disc 100 can be changed relative to the phase position of the feed phase determined by the control discs 101, 102.
  • the sliding sleeve 84 is shifted completely to the right, so that its coupling member or coupling members 103 mesh with the coupling members 104 of the drive shaft 11.
  • the locking member 97 By inserting the locking member 97 into the recess 96 of the drive shaft 11, the same is locked.
  • the bushing section 83 can now be rotated on the drive shaft 11.
  • the feed phase can be changed in an extremely simple manner relative to the phase of the intermediate ventilation of the feed device, so that the feed device can be used in a wide range for the most varied processing of a sheet metal strip, e.g. can be adjusted extremely easily and quickly in a punch press.
