Definitions

  • a processing line receives strip material continuously from an accumulator which, in turn, receives and stores a quantity of material from an input supply coil mounted on an uncoiling apparatus.
  • a sens ing device associated with the uncoiler, monitors the amount of strip remaining on the input coil and when a predetermined amount of strip remains on the coil, the input to the accumulator stops and the accumulator empties to the process line.
  • the amount of strip remaining on the coil is preferably an amount equal to the capacity of the accumulator or the capacity plus the amount of strip which would be used by the process line during the time in which the accumulator is subsequently filled.
  • the accumulator 30 shown is generally of the type depicted in detail in US. Pat. No. 3,506,210, to which reference is made for whatever details might be necessary to fully understand the operation thereof; however, the invention described herein is capable of operation with any type of accumulating device, many of which are well known in the art.
  • a plurality of drive wheels 3 when activated, pull the strip S from the uncoiler and into the accumulator.
  • the strip is transferred past guide and support rolls 32, which may also be driven or which may, in fact, be driven instead of wheels 31, to form an outer loop of strip material defined by a plurality of outer basket rolls 33.
  • the material travels around the outer basket rolls 33 and forms a free loop 34 as it is turned toward a series of rolls 35 which together form an inner basket loop of strip material.
  • the strip on the inside of the inner loop defined by rolls 35 is transferred around a take-out arbor 36 and guided by rolls 37 to the processing line.
  • the automatic operation of the accumulator is primarily accomplished by the controlled activation and deactivation of the drive wheels 31 by a control device, indicated generally by the numeral 40, which includes a stand 41 that pivotally carries a control arm 42. Stand 41 also provides a means to mount a limit switch control box 43 which, as will hereinafter become evident, monitors the position of the arm 42. While limit switches have been schematically shown herein as part of the controlling device, it is evident that any type of device which would send an electrical or other signal to a control panel (not shown) to operate the motor which drives wheels 31 would be satisfactory.
  • the accumulator 30 With arm 42 in the solid line A position in the drawing, the accumulator 30 is deactivated and receiving no strip S, This would occur primarily at times when coils are being changed With a fresh coil 13 placed on uncoiler 10, arm 42 is pivoted to the chain line B position in the drawing with roller 44 on the end of arm 42 riding on the strip material in the coil, In this position, the accumulator 30 can be activated to store the strip S therein. In a typical situation, the accumulator will fill at a rate of, for example, 800 feet per minute with typical process lines requiring 200 feet per minute. In such cases. after slightly over a minute of operation, if accumulator 30 has a capacity of, for example, 600 feet of material.
  • a limit switch in box 43 stops drive wheels 31 and permits the accumulator 30 to substantially empty to the process line.
  • position C should be selected so that the feed to accumulator 30 is deactivated when a volume of strip S substantially equal to the capacity of the accumulator remains on coil 13, or preferably when a volume of strip S equal to the accumulator capacity plus an amount equal to the strip which will be used by the process line during the filling of the accumulator remains on coil 13. Even 5 more specifically.
  • position C may be based on a full accumulation of material of the heaviest gauge contemplated for use which, of course, would be less material (in length) than that of lighter gauges which could be stored.
  • a full accumulation of material of the heaviest gauge contemplated for use which, of course, would be less material (in length) than that of lighter gauges which could be stored.
  • position C would be set at a point when approximately 800 feet of strip remained on coil 13.
  • limit switch 39 or other control senses the absence of strip material and starts the accumulator again which runs until arm position D occurs which trips another limit switch in box 43 to stop the accumulator momentarily
  • the accumulator is substantially filled to capacity.
  • the last 800 feet of coil have been run into the accumulator (with 200 feet having been used by the process line) between the time represented by arm positions C and D.
  • a method according to claim 1 comprising the additional step of, after the second stoppage of the feed moving the end of the strip material at a slow speed to position the same for attachment to the strip material from the new coil.
  • said sensing means including means to render said accumulator inoperative.
