Abstract

1336364 Roller conveyers GEC-ELLIOTT MECHANICAL HANDLING Ltd 26 Mav 1972 [27 May 1971] 17565/71 Heading B8A In an accumulating roller conveyer, an article-supporting roller R1 I is itself supported on pivotally mounted arms R1A of which the rearward portions are engageable with the leading portions of arms R3A supporting a roller R3. The other rollers are similarly arranged and supported. A drive belt B is supported on rollers SI, S2.... In Fig. 3, the roller R1 is depressed into engagement with the belt by an article A1 which is thus conveyed; an article A2 is similarly conveyed. If article A is halted by a stop ST, Fig. 4, article A2 is also halted since all rollers R4-R6 are raised clear of the belt due to the action of the arms R1A-R4A. In Fig. 6, a manually or otherwise operated stop device ST includes cam means 13 which also causes the roller R1 to be lifted clear of the belt B. In a further construction, Fig. 9, the belt is dispensed with and, under the weight of an article the rollers R1 ... are brought into engagement with friction-surfaced drive rollers 22. The article may be propelled directly by a belt (B) which runs between two series of rollers (R1), Fig. 12 (not shown), or there may be belts on either side of a central series of rollers, Fig. 13 (not shown). There may be three or more lines of rollers and driving means between the lines. Chains with friction upper surfaces may replace the belts.
