Definitions

  • the present invention relates to an automatic band changing device.
  • the invention finds a particularly advantageous application in the field of machining industries, such as punching or stamping, using metals delivered in the form of strips rolled up on a reel.
  • This change of reel can require a delay of a few minutes which, repeated several tens of times a day, results in a loss of production and relatively large turnover.
  • the aim of the present invention is to propose an automatic band changing device which would make it possible to avoid these too long interruptions of the machining proper and to increase the production and the yield of the installations accordingly.
  • the next strip is placed in masked time in the corresponding trainer and is ready to enter the orienter as soon as the latter has been tilted following the detection of the end of said previous strip.
  • the band change operation is therefore done automatically, with a minimum of manual intervention and practically without wasting time.
  • Figure 1a is a side view of an automatic coil change device according to the invention, to the receiving unit.
  • Figure 1b is a side view of a receiving unit of the automatic band changing device of Figure 1a.
  • Figures 2a and 2b are top views corresponding to Figures 1a and 1b respectively.
  • FIGS. 1a and 2a show, in side view and in plan view, an automatic band changing device intended to bring alternately a band A and a band B into a receiving unit from two reel tape unwinders, not shown in Figures 1a and 2a.
  • the two coils can be arranged either horizontally, their axes being coincident and vertical, with the bands A, B turning from the vertical position to the horizontal position, or vertically, their axes being parallel and horizontal. In both cases, an automatic adjustment of the alignment of the strips relative to the input of the device is provided.
  • this device comprises two motorized coaches 10a, 10b associated respectively with each unwinder, the function of which is to receive and drive the strip A or B coming from the corresponding unwinder to a tilting orienter 20 between two positions I, II associated respectively with each driver 10a, 10b, and intended to guide the corresponding strip A or B towards a reception unit which will be described in detail below.
  • two detectors 11a, 11b at the start of the strip are arranged at the output of the coaches 10a, 10b, which deliver a positive signal when the start of a strip appears at the output of the corresponding trainer.
  • an end-of-band detector 30, also of the photoelectric type, placed downstream of the orienter 20, provides a positive signal each time the end of a band appears at the output of said orienter.
  • the signal delivered by said end of band detector 30 is applied to tilting control means of the orienter 20, capable of bringing said orienter from one position I, II to the other when the end of band detector 30 provides a positive signal.
  • the signals delivered by the tape start detectors 11a, 11b and the tape end detector 30 are applied to means for controlling the coaches 10a, 10b so as to prohibit the operation of each coach when the detector 11a, 11b corresponding delivers a positive signal in the absence of a positive signal from the end of band detector 30.
  • these control means are also able to put said coaches 10a, 10b into operation when, following a positive signal delivered by the detector 11a, 11b at the start of the corresponding band, the detector 30 at the end of tape gives a positive signal.
  • control means of each driver 10a, 10b are capable of operating said driver step by step as long as the corresponding strip start detector 11a, 11b has not delivered a positive signal.
  • the orienter 20 being in position I, one introduces, in masked time, the strip B piecemeal in the trainer 10b, until the beginning of the strip B appears at the output of said trainer. At this time, the operation of the driver 10b is stopped since the detector 11b at the start of the strip provides a positive signal in the absence of a positive signal from the detector 30 at the end of the strip, the strip A being still present in the device.
  • Figures 1b and 2b show a tape receiving unit which can be seen that it comprises at its end two motorized drive rollers 101, 102 intended to hold and drive the current tape whose end has just been detected by the end of band detector 30, this so that it does not escape under the effect of its own weight without being retained. Said rollers 101, 102 also have the function of taking over the next strip after it has succeeded the previous strip in the receiving unit.
  • the reception unit can n ' be a guide unit comprising only the drive rollers 101, 102.
  • the invention then proposes as a reception unit a unit for guiding and welding a next band against the previous band.
  • the timing of the drive 10b of the next strip B, the timing of the rollers 101, 102 for driving the previous strip, as well as the cutting of the start of the next strip and the cutting of the end of the previous strip are controlled. by the end of band detector 30 since at this time the positions of the two bands A, B are known.
  • a photoelectric cell display device 70 coupled to the welding device 80, controls the timing of the drive rollers 101, 102 and of the driver 10b so as to attach and weld the start of the next strip B cut at the end of the previous strip A cut.
  • control means of the driver 10b of the next band B are able, as soon as the end of band detector 30 has delivered a positive signal, to drive said next band B at a catch-up speed greater than the driving speed of the previous strip A imposed by the drive rollers 101, 102.
  • said motorized drive rollers 101, 102 make it possible to accelerate the previous strips A and next B welded, this in order to reconstitute, for example, the safety loop at the entrance of a stamping machine in connection with a loop support table.
