Definitions

  • the invention relates to a positioning device for bundles to be placed on a reel drum, in particular made of metal strip, consisting of a lifting carriage for the coil and a measuring device for detecting the position of the inner coil diameter, the measured values of which are a control device for height adjustment and for moving the lifting carriage relative to the reel drum recycled.
  • the cause of such a collision can be that when the position of the inner diameter is detected indirectly via the outer diameter, the inner diameter is eccentric to the outer diameter. If the inside diameter is recorded directly at diametrically opposite points, collisions can occur because the inside diameter is oval-shaped and / or the inside winding protrudes laterally inwards with the beginning of the strip and / or the inside diameter is offset eccentrically to the side.
  • a further error when attaching the collar can be that the beginning of the band or the band tongue does not get into the recess provided for this on the reel. When the reel spreader is spread, this means that the bundle sits eccentrically on the reel drum, which can lead to fluctuations in tape tension when the bundle runs out of the reel drum.
  • the invention has for its object to provide a positioning device for bundles to be placed on a reel drum, which ensures trouble-free placement of the bundles on the reel drum.
  • the measuring device has a 360 o be measured, the inner contour of the Federal sensing measuring head and the control device from a comparison of said contour with corresponding values for the coiling drum actuators for the height adjustment of the lifting carriage and / or the lateral displacement of the bundle on the pallet truck and / or the relative rotation between the collar and the reel drum.
  • the inside diameter of the collar is measured over the entire circumference, so that it can be determined by comparison with the corresponding values for the reel drum whether there is sufficient play between the inside diameter of the collar and the reel drum over the entire circumference for trouble-free attachment exists or not.
  • the collar can be positioned using the various positioning movements so that the overlaps are eliminated.
  • the correction can be carried out with one or more adjustment processes.
  • the measuring head is adjustable in the direction of the collar axis to detect the position of the collar on the pallet truck the control device determines the travel of the lifting truck as a function of these measured values.
  • the measuring head can be set up to detect the end face of the collar and can be adjusted radially to the collar. A possible axial offset of the collar can be determined from the distance values found in this way and taken into account when determining the travel path.
  • a lifting carriage 3 In order to push a collar 1 onto a reel drum 2, a lifting carriage 3 is provided, which can be moved on rails between a receiving position shown on the right in FIG. 1 and a transfer position shown on the left in FIG. 1.
  • the pallet truck 3 is with a height and side-adjustable, trough-shaped support element 5, on which the collar 1 rests during the process.
  • rollers 6, 7 arranged parallel to one another on both sides are provided as support and centering elements for the collar 1. With the support element 5 lowered, it is possible to rotate the collar 1 with these rollers 6, 7.
  • a carriage 9 can be moved on a rail 8 by means of a drive 10.
  • the carriage 9 carries, on an arm 11, a measuring device 13 with a rotating measuring head 13.
  • the measuring head 13 comprises a distance sensor 13a.
  • the measuring head 13 can be moved into the inner opening of the collar 1 by means of the driven slide 9.
  • the inner contour of the collar 1 can then be detected by means of the measuring head 13.
  • An inwardly projecting band tongue 14 is also detected.
  • FIG. 3 shows the diagram of the inner contour recorded in this way.
  • the diagram shows that the band tongue 14 is at about 300 o . Since the diagram provides a constant value, the figure is centered on the measuring head and circular.
  • This measurement result is delivered to the control device, which compares it with the position of the reel drum 2. Since the central opening of the collar 1 is already centered, only height positioning and possibly a twisting of the collar with regard to a recess on the circumference of the reel drum 2 are considered for the band tongue 14.
  • Figures 4 and 5 differs from that of Figures 1 and 2 only in that the collar 1 'has a smaller outer diameter.
  • the result is that the inner diameter of the collar 1 'is eccentric with respect to the fixed measuring head 12. This is also expressed in the diagram in FIG. 6.
  • the eccentricity can be determined by comparing the values 0 o / 360 o and 180 o , so that, depending on this eccentricity, the lifting truck 3 can be raised until the central opening is eccentric. If the measurement were repeated, the diagram in FIG. 3 would be measured.
  • FIGS. 7 to 11 show that the measuring device 12 can be adjusted in height with the measuring head 13 and moved axially over the collar 1. 7, the measuring head 13 is moved axially.
  • a distance meter integrated in the drive 10 delivers corresponding measured values to the control device.
  • the travel path begins from the initial position shown in FIG. 7.
  • a first signal is delivered when the distance sensor 13a strikes the front edge of the bundle 1, that is the position in FIG. 8.
  • the path covered so far is recorded because it provides information about the position of the bundle 1 on the pallet truck 3.
  • a second signal is provided when the distance sensor 13a leaves the rear edge of the collar 1.
  • the value between these two signals is the fret width b.
  • the control device can determine the travel path of the bundle 1 placed in any axial position on the lifting truck 3, so that the bundle is plugged onto the reel drum 2 in a specific desired axial position.
  • the measuring head 12 After the axial position of the collar 1 on the pallet truck 3 and the width of the collar 1 have been detected, the measuring head 12 is moved into the position for detecting the inner contour of the collar 1, as shown in FIG. The previously recorded measured values are used for this positioning. Since the measuring head 13 has the distance sensor 13a, it also detects the distance h 1 from the apex of the federal government 1. Taking into account its known distance h 1 from the supporting element 5, the distance h m can be determined in the measuring device in order to move the measuring head 13 to the central position , as shown in Figure 11. This position corresponds to that in Figure 1.
  • the measuring head 13, as shown in FIGS. 12 to 14, can be equipped with a further distance sensor 13b arranged on the end face.
  • the end face of the collar 1 can be detected with this distance sensor 13b.
  • This measurement is used to record any axial displacements of the individual layers of the federal government 1, but it can also be used to record the top and bottom vertices of the inner opening.
  • the detection of a possible layer shift is important in connection with the detection of the width b. If the outer layers are axially offset from one another, the distance sensor 13a which detects the width does not determine the actual width, but rather a larger width. This incorrect measurement result can be corrected by detecting the end face, so that, as a result, the collar 1 can be positioned axially correctly on the reel drum 2.
  • the position value h m for the measuring head 13 for detecting the inner contour can also be determined, so that the measuring device detects a diagram corresponding to FIG. 15 for a circular, non-offset contour.
