Description

  The present invention relates to a band discharging apparatus provided in a band cutting apparatus for automatically cutting a binding band obtained by winding a thin sheet into a coil (in the present specification and claims, simply "coil"). .

  In order to make it easy to handle thin plates, for example, thin steel plates in storage and transportation, the outer peripheral surface is wound and bound by a binding band in a state (form) in which a long sheet is wound in a coil shape.

  An apparatus for automatically cutting such a binding band is disclosed, for example, in Patent Document 1. Patent Document 1 describes a device configured to hold a binding band with a pair of claws, float the binding band from the surface (peripheral surface) of a coil, and cut by a cutting blade.

  In such an apparatus, for example, it is configured to wind up the cut binding band to create a spiral waste band, and discharge in a bowl shape for discharging the created waste band to the outside (collection container). A chute is provided. The discharge chute is inclined and configured such that the waste band rolls down the discharge chute and is discharged to the collection container. Among devices configured in this way (hereinafter referred to as "band cutting processing device"), for example, there are devices configured such that the entire device can be rotated or translated.

  For example, when one coil is bound by a plurality of binding bands, the entire device is translated along the winding axis (core axis) of the coil, and each binding band is cut in turn and wound up. Waste and discharge to the discharge chute. In this case, since the discharge chute also moves in parallel, in order to immediately discharge the waste band discharged to the discharge chute to the collection container, for example, it is conceivable to make the collection container longer. However, in general, the collection container is compacted to be able to temporarily hold a plurality of waste bands on the discharge chute, and the entire apparatus is moved so that the discharge end of the discharge chute is located above the collection container. Sometimes, it is configured to discharge multiple waste bands from the discharge chute into a collection container.

  Also, for example, as shown in FIG. 2, a band cutting process in which the coils C1 and C2 bundled by one bundling band are disposed to face each other and configured to be horizontally rotatable between the two coils C1 and C2 When the apparatus is disposed and one recovery container 100 is disposed, for example, when the band cutting processing apparatus performs processing for removing the binding band of the left and right coils C1 and C2, binding of the right or left coil is performed, for example. When the band is cut and wound up, the waste band can be temporarily held on the discharge chute, and the entire apparatus is rotated so that the discharge end of the discharge chute is located above the recovery container 100 The waste band is discharged from the discharge chute into the collection container 100.

  As described above, when the waste band is discharged to the scaly discharge chute, if the discharge end of the discharge chute is not positioned above the collection container, the waste band is immediately discharged from the discharge chute to the collection container. The waste band is configured to be temporarily held on the discharge chute because it can not be discharged. For example, a band stopper for stopping the waste band is provided in the middle of the discharge chute, and by operating this band stopper, the waste band can be stopped and temporarily held on the discharge chute. Any band stopper may be used as long as the waste band rolling down the discharge chute can be temporarily stopped. For example, the rod member is extended by the expansion and contraction operation of the pneumatic cylinder, and one side wall of the discharge chute is passed over the discharge chute. There are those that are configured to project and exit. In addition, as the band stopper, there is also one configured using a shutter or the like that can open and close the transfer path of the discharge chute.

JP, 2010-1061, A

  However, the waste band temporarily held (stopped) on the discharge chute by the band stopper as described above becomes, for example, in a stretched state between the side walls of both sides of the discharge chute, and even if the holding by the band stopper is released, It may not be discharged from the discharge chute. Furthermore, when a plurality of waste bands are temporarily held on the discharge chute, the plurality of waste bands may be intertwined, and even if the holding by the band stopper is released, the waste chute may not be discharged from the discharge chute.

  The present invention has been made to solve the above problems, and a band discharging device capable of reliably discharging after temporarily holding a binding band (waste band) which has been cut and wound spirally. The purpose is to provide.

  In order to achieve the above object, a band discharging device according to an aspect of the present invention cuts a binding band wound around an outer peripheral surface of a coil formed by winding a thin plate to bind the coil. A band discharging device provided in a band cutting apparatus for spirally winding the cut binding band to create a waste band, and temporarily holding the waste band and discharging the waste band to the outside; Is provided at one end, and the transfer means for transferring the waste band and discharging from the other end, and is provided rotatably on the other end side of the transfer means around a horizontal axis, from the other end of the transfer means Holding means for temporarily holding the waste band to be discharged on the inner bottom surface thereof, and the holding means for holding the waste band when the waste band is discharged to the outside And a rotating means for rotating around said horizontal axis so as to face downward.

  According to this configuration, the waste band transferred by the transfer means is temporarily held by the holding means, and when discharging the waste band to the outside, the holding means is rotated so that the inner bottom surface thereof is directed downward. Therefore, the waste band can be reliably discharged by the centrifugal force generated at that time.

  In addition, the transfer means may be configured as a chute-like chute inclined such that the other end is lower than the one end to which the waste band is supplied. Thereby, the transfer means can be easily configured.

  Further, the holding means is disposed on the other end side of the chute-like chute so that the other end is lower than one end closer to the chute-like chute, and the chute-like chute And a receiving plate provided to close the other end of the weir for receiving the waste band supplied from the chute-like chute.

Each of the grip blocks 31 and 32 is mounted movably in the horizontal direction (direction of arrows 15 and 16) using a linear guide or the like. Further, the two gripping blocks 31 and 32 are moved toward and away from each other by the expansion and contraction operation of the hydraulic cylinder 3A (see FIG. 6). Further, by the expansion and contraction operation of the pneumatic cylinder 3C (see FIG. 6), the lateral feeding operation (for example, the movement operation in the direction of the arrow 15 and the reverse direction thereof) of the two holding blocks 31 and 32 is performed.

  Here, for example, as shown in FIG. 1, the band cutting operation in the case of performing the process on the coil C1 will be described.

  First, the control device 8 tilts the swinging post 2 from the origin position toward the coil C1 centering on the pivot shaft 2a, and the holding and cutting device 3 disposed at the tip of the swinging post 2 is the outer periphery of the coil C1. Abut the surface. At this time, first, the control device 8 advances the retractable coil detection rod 10 and advances the hydraulic cylinder 2A so that the coil detection rod 10 contacts the coil C1 and the coil C1 is detected.

It is moved in the axial direction (moving in the direction indicated by the arrow 15 in FIG. 3A). During this movement, as shown in FIG. 3 (b), the binding band B is locked to the grip portion 32 a of the grip block 32.

  Next, the control device 8 performs an approaching operation of the two gripping blocks 31 and 32. In this approach operation, the control device 8 causes the hydraulic cylinder 3A to contract so that the gripping block 31 moves in the direction of the arrow 16 and the two gripping blocks 31 and 32 move as shown in FIG. 3C. The grip portion 31a of the grip block 31 gets under the binding band B locked by the grip portion 32a, and the binding band B is gripped between the pair of grip portions 31a and 32a.

  Next, the control device 8 causes the cutting blade 33 to swing around the shaft 33 a in the direction of the arrow 17 to cut the binding band B by causing the hydraulic cylinder 3 B to extend and contract. Even after this cutting, the control device 8 maintains the contracted state of the hydraulic cylinder 3A, thereby maintaining the state in which the one end of the binding band B is gripped by the pair of gripping portions 31a and 32a.

  Next, the control device 8 causes the hydraulic cylinder 2A to contract, thereby returning the swinging post 2 to the home position, and detaching the gripping and cutting device 3 from the outer peripheral surface of the coil C1.

  Thus, the band cutting operation is completed, and then the band winding operation is performed. The band winding operation will be described after the description of the lifting device 5 and the winding device 4.

At the end of the above-mentioned band cutting operation, the swinging post 2 is returned to the home position by swinging the swinging post 2 backward while holding the one end of the cut binding band B while the holding and cutting device 3 holds it.

  In the subsequent band winding operation, the control device 8 first retracts the binding band B cut by the push-up fittings 5a and 5b as shown in FIG. 4 by contracting the pneumatic cylinder 5A. Push up to the removal device 4 side. At this time, the binding band B is pressed against the take-up roller 4c. Thereafter, the pressure rollers 4a and 4b are inserted in front of the user from the back of the sheet of FIG. As a result, the binding band B is sandwiched between the winding roller 4c and the pressure rollers 4a and 4b. At this time, the pneumatic cylinder 9A is stopped in the rod contraction state, and the rocking chute 9 is in contact with the binding band B in a downward sloping state shown by a broken line in FIG. The push-up fittings 5a and 5b of the push-up device 5 are returned to their standby positions by the expansion operation of the pneumatic cylinder 5A.

  Thereafter, the gripping of the binding band B by the gripping and cutting device 3 is released, and the winding roller 4c is rotationally driven at a low speed so that the binding band B moves in the rewinding direction indicated by the arrow 13. When the tip end of the binding band B separates from the swinging chute 9, the rod of the pneumatic cylinder 9A is at the most retracted position, so when it is detected by the pneumatic cylinder 9A (with sensor), it is immediately wound up. The rotation of the roller 4c is reversed to drive at high speed. As a result, the binding band B moves in the winding direction indicated by the arrow 14 and is wound in a state in which the pressing rollers 4a and 4b are pressed against the winding roller 4c.
