Abstract
Abstract Two parallel lines 13, 14 of six-packs 10 are continuously delivered to a stop device 38 and starting conveyor 19 disposed above a stationary platform 24 by a belt conveyor 15. The stop device and starting conveyor carry downwardly depending pins 39, 40; 22, 23 that are synchronously driven both transverse to and in the transport direction. These pins separate the six-packs into groups 18 of two and accelerate them to an intermediate conveyor 20 running at the same speed and comprising endless chains 30 mounting transverse bars 29 that pass through opening slots 26, 28 at the beginning and end of the conveyor 20 and engage the six-pack groups at their rear ends. The groups converge along the conveyor 20, at the end of which they are engaged by an end conveyor 21 in the form of a slide member 31 coupled to a pantograph linkage and driven by a chain drive 33. The slide member has front and rear arms 41, 32 that engage the converged six-pack groups 18 and accelerate them onto a partially folded carton blank 11, where they are halted in a properly registered position by a yieldable end stop member 36. The loaded blank is then removed transverse to the feed direction for further wrapping, and a fresh blank is fed into the loading station. The spaced separation of the groups and their accelerated movement by the end conveyor allows time for the removal and replacement of the carton blanks, and the return of the slide member to engage a fresh group of six-packs.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
304 words
An apparatus for forming and conveying packs of articles, particularly bottles and cans, to a packing container, comprising: (a) a feed conveyor (15) for continuously supplying article packs (10) to an input end of a transport path of the apparatus in two distinct lines (13,14), (b) means including a stopping device (38) and a beginning conveyor (19) disposed in the transport path following the feed conveyor for receiving the article packs, separating them into plural pack groups (18), and delivering the groups to an input end of an intermediate conveyor (20) disposed in the transport path following said means, said beginning conveyor (19) accelerating the groups (18) to the speed of said intermediate conveyor (20), (c) an end conveyor (21) disposed in the transport path following the intermediate conveyor for receiving the pack groups therefrom and transporting them to a final stop position at a packing station, said end conveyor comprising: (1) a movable slide member (31) disposed above the transport path, (2) means for lowering the slide member, (3) a pusher plate (32) depending downwardly from the slide member for engaging the rear ends of pack groups upon the lowering of the slide member, (4) a counterstop (41) spaced from the pusher plate and depending downwardly from the slide member for engaging the front ends of pack groups, (5) means for driving the slide member at a higher horizontal conveying speed than the intermediate conveyor to thereby accelerate pack groups engaged by the slide member away from those behind to provide sufficient handling time at the stop position before the next pack groups arrive, and (d) a yieldable end stop (36) for determining the stopping position of the pack groups, said end stop being operable to move toward the approaching groups and then be driven back with the groups to said stopping position.
Claim 2
Independent Claim
304 words
An apparatus for forming and conveying packs of articles, particularly bottles and cans, to a packing container, comprising: (a) a feed conveyor (15) for continuously supplying article packs (10) to an input end of a transport path of the apparatus in two distinct lines (13,14), (b) means including a stopping device (38) and a beginning conveyor (19) disposed in the transport path following the feed conveyor for receiving the article packs, separating them into plural pack groups (18), and delivering the groups to an input end of an intermediate conveyor (20) disposed in the transport path following said means, said beginning conveyor (19) accelerating the groups (18) to the speed of said intermediate conveyor (20), (c) an end conveyor (21) disposed in the transport path following the intermediate conveyor for receiving the pack groups therefrom and transporting them to a final stop position at a packing station, said end conveyor comprising: (1) a movable slide member (31) disposed above the transport path, (2) means for lowering the slide member, (3) a pusher plate (32) depending downwardly from the slide member for engaging the rear ends of pack groups upon the lowering of the slide member, (4) a counterstop (41) spaced from the pusher plate and depending downwardly from the slide member for engaging the front ends of pack groups, (5) means for driving the slide member at a higher horizontal conveying speed than the intermediate conveyor to thereby accelerate pack groups engaged by the slide member away from those behind to provide sufficient handling time at the stop position before the next pack groups arrive, and (d) a yieldable end stop (36) for determining the stopping position of the pack groups, said end stop being operable to move toward the approaching groups and then be driven back with the groups to said stopping position.
Claim 3
Dependent Claim
55 words
An apparatus according to claim 1, wherein the intermediate conveyor comprises a plurality of push rods (29) arranged transversely between parallel endless chains (30), and the end conveyor is disposed above the intermediate conveyor such that the slide member can be lowered into an end area of the intermediate conveyor to engage pack groups thereon.
Claim 4
Dependent Claim
