Abstract: 763,621. Sheet delivery apparatus. IGRANIG ELECTRIC CO., Ltd. Jan. 1, 1954 [Jan. 2, 1953], No. 33/54. Class 100(1). [Also in Group XL(b)] In a device for counting, stacking in bundles and delivering bundles of flat articles which are conveyed to selected receivers movable from article receiving to article delivery position, selecting means controlled by the counter are provided for causing one receiver to move to delivery position while the other receiver is receiving articles. Sheet conveyer mechanism sheet stiffening arrangemets:-As shown magazines 12 are conveyed by a conveyer 14 towards a vane 52 which serves to direct the magazines from a conveyer 20 between conveyers 42 and 60 or to allow them to continue along the conveyer 20 and between rollers 24 and 36 to a receiver 37. Magazines diverted by the vane 52 are carried by conveyer 42 to further rollers 48 and 36 and deposited in a receiver 54. The conveyers are driven by a motor 86 and transmission indicated at 88, 90 and 92. The shafts 26 and 50 carrying the rollers 24 and 48 are each provided with a roller 28, of greater diameter than the rollers 24, 48 cooperating with a roller 34, of less diameter than the rollers 36, so that the magazines are given a bowed configuration to stiffen during delivery to the receivers 37, 54. Receivers:-The receivers 54 each comprise a back 100 and sides 102 to which are connected supports 96 running between rollers 98 and co-operating with cam operated levers 116, 118 by which the receivers may be raised and lowered. The bottom of the receivers comprise slats 104, 106 having downwardly sloped leading portions 108 to accommodate the thicker folded edges of the magazines. The receivers are open at the front, fixed guard plate 109 having extension 110 serving to retain the magazines in the receivers where they are in the part not shown in Fig. 1. The guard plates are made in two sections. adjustable to accommodate magazines of different width and are mounted on a framework by fastening means 112. When a receiver is lowered by means of the supports 96 and levers 116, 118, the belts of a delivery conveyer 132 engage the magazines between the slats 104, 106 and remove them from the receiver. The conveyer 132 is driven from the motor 86 by a transmission link 142. Delivery in counted batches:-As the magazine 12 passes along the conveyer 14 the spaces therebetween are detected by a photoclay P and co-operating light source Lt. After a predetermined count has been made a relay V is operated to raise the vane 52 so that the magazines are then delivered to the receiver 37. At this time a batch counter BC controlled by the counting mechanism P, Lt, causes operation of a clutch solenoid MB which in turn operates a cam 124 to lower the receiver 54. and deliver the magazine to the conveyer 132: The cam 124 makes a complete rotation, thus raising the receiver, the clutch soleoil MB then being rendered in operation by the action of a limit switch MB1. After a predetermined number of magazines has been delivered to the receiver 37 the photoclay P causes de-energization of the relay V to lower the vane 52 so that magazines are delivered to the receiver 54 while the receiver 37 is lowered to deliver magazines to the delivery conveyer 132. An electric control circuit. (Fig. 9, not shown) is provided for controlling the operation of the receiver raising and lowering devices and the movement of the vane 52, and for synchronizing those operations.
