Abstract

1,027,034. Packaging machines. MEAD CORPORATION. Jan. 28, 1963, No. 3410/63. Heading B8C. A machine for packing cans in cases comprises a feed conveyer 15 acting in conjunction with pressure rollers 30<SP>1</SP>-30<SP>4</SP> to advance the four rows of cans on to side rails where each batch of cans is arrested by its appropriate stop 42. When the correct number of cans is in position in each lane, separating fingers 60, 66 are raised to separate the cans X (Fig. 1) from the batch, so that the platform 144 connected to the chain 130 can first raise the cans and then advance them to beyond the stop 42 where they are again deposited on the side rails. The platform 144 is maintained in the horizontal position by the parallel links 160, 161 pivoted to the member 164 which slides longitudinally of the machine in guides 168, 168<SP>1</SP>. Also connected to the chain 130 is an upper-tier carrier 244 mounted on pillars 243 from the pusher member 242, 248. In Fig. 1 this carrier has deposited the cans W on the upper rails 40<SP>2</SP> and is descending to pick up the batch of cans following the cans X. When the carrier 244 is carrying the cans W into position the pusher member 248 engages the previously positioned upper and lower tiers of cans into the open end of the case 170. When the case is full, the platform 172 is pivoted downwardly about its pivot 175 to the position shown in Fig. 1 ready for unloading. The drive to the chain 130 is not made until all the lanes have got the correct number of cans to engage the respective stops 42 and a case 170 is in position to receive the cans.
