Abstract
Abstract When piece goods are transported on continuous conveyors, it is often impossible to prevent some of the piece goods from having to be stopped momentarily when the conveyor continues the run. In order, very substantially, to prevent the resulting mechanical stresses on the piece goods, especially the frictional stresses, caused by the continuous conveyor which continues to run, the invention proposes a continuous conveyor of simple construction with only a single tension member (sheathed chain 10), on which freely rotatable pile-up rollers (12, 39) are arranged on both sides as a carrying member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A continuous carry-chain conveyor for transporting piece goods such as cigarette packs, said chain conveyor comprising freely rotatable pile-up rollers which are moved in the direction of conveyance, and upon which the piece goods rest, and, in situations of an accumulation of the piece goods, continuously move underneath the piece goods, in a rotating manner including: a sheathed chain, wherein the pile-up rollers are arranged on both sides of said sheathed chain, said sheathed chain having a plurality of links comprising inner and outer plates arranged sequentially and attached together by chain bolts which are arranged successively in equally laterally protruding pairs, characterized in that each of said pile-up rollers is arranged on a cantilever portion of a first chain bolt of one of said pairs of chain bolts; and further comprising an end plate arranged on the free cantilevered ends of said one pair of chain bolts, each end plate connecting the free cantilevered ends of said one of said pairs of chain bolts.
Claim 2
Dependent Claim
165 words
A continuous carry-chain conveyor for transporting piece goods such as cigarette packs, said chain conveyor comprising freely rotatable pile-up rollers which are moved in the direction of conveyance, and upon which the piece goods rest, and, in situations of an accumulation of the piece goods, continuously move underneath the piece goods, in a rotating manner including: a sheathed chain, wherein the pile-up rollers are arranged on both sides of said sheathed chain, said sheathed chain having a plurality of links comprising inner and outer plates arranged sequentially and attached together by chain bolts which are arranged successively in equally laterally protruding pairs, characterized in that each of said pile-up rollers is arranged on a cantilever portion of a first chain bolt of one of said pairs of chain bolts; and further comprising an end plate arranged on the free cantilevered ends of said one pair of chain bolts, each end plate connecting the free cantilevered ends of said one of said pairs of chain bolts.
Claim 3
Dependent Claim
39 words
The continuous conveyor according to claim 1, further comprising a spacer sleeve, projecting the length slightly beyond the length of the pile-up roller, and arranged on the second chain bolt of said one of said pairs of chain bolts.
Claim 4
Dependent Claim
22 words
The continuous conveyor according to claim 1, further comprising means for axially retaining the end plate of the pair of chain bolts.
Claim 5
Dependent Claim
25 words
The continuous conveyor of claim 3, wherein said means for axially retaining comprises a chain shackle located on the free ends of the chain bolts.
