Abstract: 1,138,902. Sheet delivering apparatus. CROWN ZELLERBACH CORP. 31 Aug., 1966 [11 Oct., 1965], No. 38937/66. Heading B6H. Paper bags 28, Fig. 2, produced in a bag making machine are delivered from the machine by a roller 29 and formed into batches 30a ... 30d, the batches being advanced to a rotating device 26 which displaces the batches through 90 degrees in alternate direction to form the batches into a stack 27 in which the edge-on stacked batches are staggered alternately. Paper bags 28 disposed about the periphery of roller 29 are stripped from the roller by stationary strippers 33a protruding into grooves on the periphery on the roller and the stripped bags are deposited successively on a table formed by a pair of spaced bars 84a, whereby the bags are formed into batches of fifty by interposition of fingers 92a, Fig. 4, mounted on pivotal support 95, which is oscillated upwardly by a rod 98 to displace the fingers 92a upwardly, the fingers 92a being also displaced away from the roller 29 by links 90a which are articulated to levers 76a oscillated by a push rod 82. Push rods 98 and 82 are actuated by cams on a drive shaft. Simultaneously with the displacement of the fingers 92a lugs 67a on an endless chain 37a are erected by cams 69a rocked clockwise by rods 73a articulated to levers 76a which are pivoted by cam controlled rods 82. The erected lugs 67a are guided with the chains 37a along arcuate guides 68a parallel to bars 35a along which the batched bags are advanced to the rotating device 26. Batches of bags 30 are delivered successively against pivotal constraining fingers 113, Fig. 5, mounted on a pin 114 and the batches at the delivery end of the chain conveyer are transferred to the rotating device 26 by a transfer platform 120a mounted on bracket 121a which is attached to a collar 122a for slidable movement along a rod 123a oscillated in a quasi-elliptical path by a cam operated crank 125a from a lower phantom indicated position through position 120a<SP>1</SP> to 120a<SP>11</SP>. Transfer of batches is assisted by a pair of spaced fingers 140, Fig. 2 attached to an oscillating, cam operated arm 135. Batches 30 are alternately received by pairs of rotary blades 142a, 143a and 142b, 143b actuated with a phase displacement of 180 degrees by quadrants 147a, 154a which are rocked by a shaft 149 to rotate the batches 30 through 90 degrees in alternate directions. Prior to rotation, however, the movable blade 143a which is mounted on a splined shaft 157a is displaced into engagement with the batch by a cam actuated lever 161a. The turned batches 30 are deposited by the blades 142a, 143a or 142b, 143b, Fig. 12, on a table comprising spaced upstanding bars 192b, 194b and spaced horizontal bars 182b mounted on a carriage mounted for vertical and horizontal sliding movement on uprights 151b, 152b (Fig. 10), and horizontal bars 186b, respectively. Batches 30 deposited by the blades on the table are first lowered downwardly under cam control and then leftwardly from position 194b indicated in solid lines to a stacking position 194b indicated in phantom lines, whereupon the upstanding bars 194b are lowered by a connecting rod 200b and the batches displaced on to a stacking table 228b by vertically reciprocated arms 2156, 216b which are first raised from below the level of table 182b and then lowered again between successive reciprocative movements of the uprights 194b, which are of sufficient width to grip the preceding batches 30 prior to lowering of the arms 215b, 216b (Fig. 15). Batches disposed between the arms 215b and 216b are jigged laterally by jigging plates 229b, Fig. 16, attached to levers 231b which are oscillated by vertical spindles 232b through links 241, 242 243 the latter of which is provided with a cam follower 256 co-acting with cam 246 and vertically by underlying jigging plates 248b mounted pivotally on links 249b which intermediate their lengths are articulated to rods 253 articulated to bellcramks which co-act through cam followers 245 with a cam 247. Batches 30 may then be associated into packs of bags e.g. containing 10 batches of alternately disposed batches. Reference has been directed by the Comptroller to Specification 1,032,425.
