1,268,676. Endless conveyer transfer mechanisms. STA-HI CORP. 16 July, 1969 [26 July, 1968], No. 35750/69. Heading B8A. An outfeed conveyer mechanism 10 for receiving and conveying units such as stacks of publications (not shown) from a preceding conveyer mechanism 12, comprising a main frame 36, carrying a conveying device 28 defining a longitudinal, generally horizontal unit receiving surface forming a unit receiving station, pusher means mounted adjacent to the unit receiving surface and movable in at least one longitudinal direction, longitudinally across the receiving surface for moving units in said at least one longitudinal direction generally horizontally from the unit receiving station, which units are received from the preceding conveyer mechanism 12, and driving means 42 operably connected to said conveying device for intermittently moving at least the pusher means in the at least one longitudinal direction. As shown, the conveyer mechanism 10 is part of the stacking device described in Specification 1,203,829. The conveyer 28 comprises an endless belt 38 which is associated with an endless conveyer chain 46 carrying three pushers 48. The drive to the belt 38 and pushers 48 is from a continuously running motor 66 to two vertical shafts 42. Each of the latter drives through a clutch 62 to drive shafts at respective separate ends of the conveyer. One of the shafts 42 (on the power side of its associated clutch 62) has an electrically operated brake 68. The latter is controlled by a switch 76 (Fig. 1) and Fig. 5 (not shown) operated by a cam 72 which is driven by a chain 70 coupled to the associated shaft 42. Operation.-As each stack is deposited on the conveyer 28, the brake 68 is released and the appropriate clutch 66 is engaged (according to which direction of transfer is intended). Two of the pushers 48 are initially positioned with one on either side of the delivered stack (as shown in Fig. 3). The chain 70, cam 72, and switch 76, cause re-actuation of the brake 68 to bring the pushers 48 back into the positions shown in Fig. 3. Selection of the direction of delivery of the conveyer 28 and pushers 48, may be determined by manually operated switch means or automatically, e.g. by electronic computer, or punched tape, control. The selection may alternatively be arranged to provide delivery in alternate directions. |
