Definitions

  • a transfer mechanism for transferring signatures from a gatherer to a binder with the transfer mechanism including a transfer conveyor driven in synchronism with the gatherer conveyor and the binder infeed conveyor until the gatherer stops whereupon the transfer conveyor is driven by the binder until the transfer conveyor is clear of signatures.
  • the transfer conveyor automatically stops and is locked in proper timed relationship with the stopped gatherer conveyor While the binder continues operating at a constant speed whereby restarting of the gatherer enables the gatherer to come up to binder speed and be synchronized with the binder before any signatures are conveyed to the binder.
  • This invention relates to a system for transferring articles from one station to another and, more particularly, to a transfer conveyor arrangement for transferring signatures from a gatherer to a binder.
  • Present day binder equipment contemplates a gatherer which feeds signatures to a signature conveying chain which, in turn, feeds thesignatures to an in-feed conveyor chain of a binder where the binding operations are performed.
  • the gatherer conveyor chain is driven by the gatherer and the binder in-feed conveyor chain is driven by the binder.
  • This equipment is designed to operate at cycles or more per minute for high speed production.
  • :It is a further object of this invention to provide a transfer conveyor system which cooperates with a gatherer and a binder to enable the gatherer to be brought up to speed and synchronized with the binder without decreasing the speed of the binder.
  • a further object of the invention is to provide a transfer conveyor which is driven in synchronism with a gath- ICC erer and a binder and which is operative upon stoppage of the gatherer to continue to feed books to the binder until the conveyor is cleared and. is then automatically stopped in the proper timed relationship to the gatherer.
  • a gatherer and a gatherer conveyor chain driven by a gatherer motor and a binder and an in-feed conveyor chain driven by a binder motor A transfer conveyor chain is positioned between the gatherer conveyor chain and the in-feed conveyor chain with the transfer conveyor chain being adapted to be driven by iboth the gatherer and binder when the two machines are operating in synchronism but, in the event of a gatherer stoppage, to be driven by the binder until the transfer conveyor chain is cleared of books. Thereafter, the transfer conveyor chain is automatically stopped while the binder continues operating at a constant speed.
  • a timing motor is then actuated to drive the transfer conveyor chain to a position where it is in proper timed relationship with the stopped gatherer conveyor chain.
  • the gatherer may then be restarted with the gatherer conveyor chain and the transfer conveyor chain driven in synchronism by the gatherer drive motor.
  • the gatherer and the transfer conveyor chain are reconnected to the binder for synchronous operation.
  • the length of the transfer conveyor chain is such that the gatherer achieves synchronous speed with the binder before any signatures are delivered to the in-feed conveyor of the binder.
  • FIG. 1 is a schematic top plan view illustration of the gatherer conveyor, the transfer conveyor and the infeed conveyor contemplated by this invention
  • iFIG. 2 is a schematic side elevation view of the conveyor system of FIG. 1;
  • FIG. 3 is a schematic lay out of a suitable drive train for the transfer conveyor system of FIGS. 1 and 2;
  • FIG. 4 illustrates in enlarged detail the encircled portion of FIG. 3
  • FIG. 5 is a schematic circuit diagram showing a suitable control circuit which may be used with the invention.
  • FIG. 1 there i's illustrated a gathererbinder combination in which a gatherer is indicated at 10 and a binder at 12 with the transfer conveyor mechanism which is the subject of this invention schematically illustrated at 14.
  • the gatherer 10 may be of any conventional construction, as shown for example in U.S. Pat. 3,311,368, and includes a main drive shaft 16 and a gatherer conveyor chain 18 having upstanding conveyor pins 20 'spaced along the length thereof. The spacing between each pin 2l) corresponds to one cycle of the gathe-rer 10.
  • the binder 12 may also be of a conventional construction and reference may be had to U.S. Pat. Nos. 3,258,798 and 3,319,499 for a disclosure of such binders.
  • the binder 12 includes an irl-feed conveyor chain 22 which is driven by the binder and which includes ⁇ upstanding conveyor pins 24.
  • a transfer conveyor chain 14 which is positioned between the gatherer conveyor chain 18 and the in-feed conveyor chain 22 to transfer signatures from the gatherer chain to the in-feed conveyor chain.
  • the conveyor mechanism comprises an endless conveyor chain 26 having upstanding conveyor pins 2S. The spacing between the pins 28 correspond to the spacing of the pins 20 and 24.
  • the transfer conveyor chain 26 is inverted with respect to the conveyor chains 18, 22 and is offset in the manner illustrated in FIG. 2.
  • the operation of the transfer conveyor chain 26 is synchronized to coincide with the operation of the two conveyor chains 18, 22. In this manner, a signature is moved in the direction of arrow 30 (FIG.
  • the drive system for the transfer conveyor mechanism is illustrated.
  • the main drive shaft 16 is adapted to be coupled through a gatherer-binder clutch 40 to the binder power shaft 42.
  • Engagement of the clutch 40 locks both the gatherer and binder into one synchronously operating system with the gatherer motor receiving its speed control signals by suitable tachometer generators and control equipment. Since the details of clutch 40 form no portion of this invention, they have been omitted; however, the clutch is commercially available on gatherer-binder equipment supplied by Harris-Intertype Corporation, Easton, Pennsylvania.
  • the drive 'system further includes a gatherer transfer drive shaft 44 connected by a chain drive 46 to the gatherer drive shaft 16 and a binder transfer drive shaft 48 connected by a chain drive 50 to the binder power shaft 42.
  • a shaft 52 coaxial with the shafts 44, 48 is adapted to be selectively connected by a gatherer clutch 54 and a binder clutch 56 to the shafts 44, 48.
  • a gear 58 connected to shaft 52 is adapted to mesh with a gear 60 which is supported on a transfer conveyor drive shaft 62.
  • the shaft 62 has a bevel gear 64 at one end thereof in meshing engagement with a gear 66 by which drive is supplied to the transfer conveyor chain 26.
  • the gear 58 also meshes with a gear 68 supported on a shaft 70 and which is selectively connected by a timing clutch 72 to a low speed gear head motor 74 for a purpose hereinafter described.
  • the transfer conveyor 26 After the transfer conveyor 26 has delivered the last of its signatures to the in-feed conveyor 22, the absence of any further signatures on the transfer conveyor 26 is detected by any suitable means, such as a series of photoelectric sensors 77, which generate a signal to open switch SW2 and disengage clutch 56 thereby interrupting all drive to the transfer conveyor chain 26.
  • any suitable means such as a series of photoelectric sensors 77, which generate a signal to open switch SW2 and disengage clutch 56 thereby interrupting all drive to the transfer conveyor chain 26.
  • a conventional speed-sensitive switch 76 is connected to the transfer conveyor drive shaft 62. This switch, which is normally open, closes when rotation of shaft 62 stops to produce a signal which engages clutch 72 and actuates motor 74 to drive the transfer conveyor chain 26 to a position where it is in time with the gatherer chain 18.
  • the proper positioning of the transfer chain with respect to the gatherer chain is signaled by a limit switch arrangement which includes a limit switch 78 and a limit switch cam 80.
  • the limit switch cam 80 is rotatably supported on the shaft 62 and includes a gear 82 which meshes with a pinion 84 on a cam drive shaft 86.
  • the shaft 86 is drivingly connected by a drive chain 88 with the gatherer conveyor shaft 44.
  • cam 80 is rotated in synchronism.
  • cam 80 also stops rotating.
  • the cam 80 has a peripheral surface which is concentric to the shaft 62 with the exception of a single high point or lobe which may be considered to correspond to the position of one of the pins 20 on the conveyor chain 18. The circumferential distance around the cam would correspond to the spacing between adjacent pins of the conveyor chain 18.
  • the rotational position of the high point on the cam 80 is indicative of the position of one of the pins 20.
  • the limit switch 78 is con nected for rotation to shaft 62 so that when the gatherer conveyor chain 18 is stopped and, hence, cam 80 stops rotating, the limit switch 78 will rotate relative to the cam 80.
  • the gatherer binder clutch 40 remains disengaged, clutch 54 has been engaged, and clutches 56 and 72 are disengaged.
  • both the gatherer conveyor chain 18 and the transfer conveyor chain 26 will operate as one unit with the transfer conveyor chain 26 being immediately available to receive signatures from the gatherer conveyor chain 18. It is an important aspect of this invention that, by reason of the clutches 40 and 56 being disengaged, the gatherer 10 may be brought up to a speed synchronous with the speed of the binder 12 without the necessity for slowing down the binder.
  • the transfer conveyor chain 26 is of such a length that suicient cycles of the gatherer 10 are available to permit the gatherer 10 and, hence, the conveyor chains 18, 26, to achieve a speed synchronous with that of the binder 12 and the in-feed conveyor chain 22 before any signatures are delivered to the in-feed conveyor.
  • the invention is particularly adapted for use in a system wherein two gatherers are feeding signatures in alternation to a single binder.
  • a transfer conveyor system of the type shown in FIGS. l and 2 would be associated with each gatherer with the two transfer conveyors cooperating with the in-feed conveyor of the binder.
  • the binder and the in-feed conveyor would operate at twice the speed of the gatherers and their associated transfer conveyors such that the in-feed conveyor would receive signatures alternately from one transfer conveyor and then the other.
  • the binder could operate at, for example, 200 books per minute while the two gatherers are each operating at 100 books per minute.
  • each transfer conveyor system would be provided with a drive and synchronizing system of the type shown in FIGS. 3 and 4.
  • a separate gatherer-binder clutch 40 would be provided for each gatherer with the conventional gear box associated with the binder providing the means to enable the binder t operate at twice the speed of the gatherer while permitting clutch 40 to interconnect each gatherer shaft with the binder shaft when the system is operating as a synchronous unit.
  • the transfer conveyor system associated with that gatherer will continue to feed signatures to the binder in alternation with the transfer conveyor of the other gatherer until it is cleared. Thereafter, the transfer conveyor for the shut-down gatherer will be stopped and re-timed with its gatherer in precisely the manner above-described. At the same time, the other gatherer will continue to deliver signatures via its transfer conveyor to the binder with both the gatherer and binder continuing to operate synchronously at speeds of 100 and 200" books per minute, respectively. Of course, with the one gatherer shut down, the binder receives only onehalf as many signatures as with both gatherers operating.
  • a system for processing articles including a first unit for delivering the articles and motor means for driving said first unit, a second unit yfor receivin the articles and motor means for driving said second unit independently of said first unit, first conveyor means for feeding the articles from said first unit toward said second unit and second conveyor means for receiving said articles and feeding the articles into said second unit, means for accumulating articles delivered by said first conveyor means and feeding the accumulated articles in timed relation to said second conveyor means and drive means for actuating said accumulating means, said drive means including means for driving said accumulating means Iby said first motor means and means for driving said accumulating means by said second motor means whereby said accumulating means may be selectively driven by either of said motor means.
