Abstract
Abstract Stow roller train for storing and conveying piece goods or cargo without stowing pressure, with rotatably mounted article-bearing rollers which are selectively drivingly coupled by intermediate rollers, with a constantly rotating traction means supported by supporting rollers. The intermediate rollers are adjustably coupled in groups. Each group of intermediate rollers is connected by means of a linkage with a feeler or probe engageable by the cargo and is thereby moved between a driving and an idling position. Respectively one intermediate roller and one supporting roller are mounted to a pivotably disposed lever. The bearing of the intermediate roller is axially fixed and radially movable with respect to the rotational axis of the intermediate roller. The supporting roller is positioned on said lever such that it automatically and simultaneously presses the traction means against the intermediate roller when said intermediate roller is being moved by the linkage toward the driving position thereof.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
229 words
A stow roller train comprising: a plurality of conveying roller sets spaced from one another in a conveying direction for sequentially conveyingly engaging articles to be conveyed, a continuously movable traction means extending adjacent said plurality of conveying roller sets, each of said conveying roller sets including an articlecarrying roller and an intermediate roller at one side of said traction means and a support roller at the other side of said traction means, article position detecting means for detecting the position of an article on said article-carrying rollers, linkage means connected to said detecting means and to respective ones of said intermediate rollers for automatically effecting movement of said intermediate rollers between driving positons with the respective intermediate roller drivingly connecting the traction means with the respective associated article-carrying roller of the same conveying roller set and idling positions with the respective intermediate roller out of driving connection with the traction means and the respective associated article-carrying roller of the same conveying roller set in dependence on the position of said article, and supporting roller mounting means interconnecting a supporting roller and intermediate roller of a given conveying set such that movement of said intermediate roller from an idling to a driving position thereof automatically results in movement of said supporting roller against the traction means to thereby press the traction means in a direction toward the intermediate roller.
Claim 2
Dependent Claim
229 words
A stow roller train comprising: a plurality of conveying roller sets spaced from one another in a conveying direction for sequentially conveyingly engaging articles to be conveyed, a continuously movable traction means extending adjacent said plurality of conveying roller sets, each of said conveying roller sets including an articlecarrying roller and an intermediate roller at one side of said traction means and a support roller at the other side of said traction means, article position detecting means for detecting the position of an article on said article-carrying rollers, linkage means connected to said detecting means and to respective ones of said intermediate rollers for automatically effecting movement of said intermediate rollers between driving positons with the respective intermediate roller drivingly connecting the traction means with the respective associated article-carrying roller of the same conveying roller set and idling positions with the respective intermediate roller out of driving connection with the traction means and the respective associated article-carrying roller of the same conveying roller set in dependence on the position of said article, and supporting roller mounting means interconnecting a supporting roller and intermediate roller of a given conveying set such that movement of said intermediate roller from an idling to a driving position thereof automatically results in movement of said supporting roller against the traction means to thereby press the traction means in a direction toward the intermediate roller.
Claim 3
Dependent Claim
70 words
A stow roller train according to claim 1, wherein said supporting roller mounting means for each conveying-roller set includes a lever and means for rotatably supporting both the intermediate roller and the support roller for a respective conveyor set on said lever, and wherein said lever is mounted for pivotal movement about a pivot axis spaced from the respective rotational axes of said support roller and intermediate roller supported thereon.
Claim 4
Dependent Claim
75 words
A stow roller train according to claim 2, wherein the means for rotatably supporting the intermediate roller at said lever includes means for preventing movement of said intermediate roller in the direction of its rotational axis and means permitting relative movement of said intermediate roller and lever in a radial direction with respect to said rotational axis so that said intermediate roller can adjust radially to driving conditions with a given position of said lever.
Claim 5
Dependent Claim
79 words
A stow roller train according to claim 1, wherein, for each conveying roller set, said supporting roller is positioned with respect to said article-carrying roller and Intermediate roller such that said movement of said supporting roller against the traction means effects a reduction in the distance between engagement points of the intermediate roller at the traction means and the article-carrying roller, whereby the tendency of said intermediate roller to jam between said traction means and article-carrying roller is reduced.
Claim 6
Dependent Claim
80 words
A stow roller train according to claim 3, wherein for each conveying roller set, said supporting roller is positioned with respect to said article carrying roller and intermediate roller such that said movement of said supporting roller against the traction means effects a reduction in the distance between engagement points of the intermediate roller at the traction means and the article-carrying roller, whereby the tendency of said intermediate roller to jam between said traction means and article-carrying roller is reduced.
Claim 7
Dependent Claim
65 words
A stow roller train according to claim 19, wherein said linkage means and detecting means include a common linkage and detector for a plurality of said conveying roller sets with several such common linkages and detectors being provided for respective separate groupings of said conveying roller sets and being operable separately from one another to control the respective conveying roller sets of the respective groupings.
