1428172 Roller conveyers SHUTTLEWORTH Inc 9 March 1973 [9 March 1972] 11512/73 Heading B8A Conveyer rollers used in a case packer 30 are mounted for rotation on driven shafts, the rollers being loosely received on the shafts. Articles are normally propelled by the rollers but if an article is braked the rollers supporting the article are also braked but the respective shafts may continue to rotate. A roller conveyer 33 comprises two groups, the rollers of group 33B rotating at a speed less than those of group 33A. Each roller 50 or 51 is mounted on a shaft 52 and may comprise a rubber outer sleeve secured on an inner sleeve of nylon. A stainless steel cover may surround the sleeve 53. Each shaft 52 in the group 33A is driven by a belt 60 engaging a shaft 59 and by belt gearing 62-66 driven by a motor 67. A shaft 68 drives the roller shafts of the group 33B but, by belt gearing 70-72, is driven at a lower speed than that of the shaft 59. To prevent permanent deformation of the shafts 52 when large loads are carried on the rollers 50, 51 bars 176 support individual rollers when the shafts are pressed downwardly. Channels for the articles are formed by guides 43 adjustably supported on transverse members 45. The packer 30 also includes a roller section 35 movable to position 35<SP>1</SP>, a vacuum head 34 and a box conveyer 32. The drive to rollers 80 of the section 35, which are similar to the rollers 50, 51 has a tubular member 86 which telescopes over the shaft 68, to provide the drive whatever the position of section 35. In operation, articles such as bottles travelling in the direction 36, accumulate between the guides 43 and, having passed on to the roller section 35, a batch is lifted therefrom by the vacuum head 34, the section 35 is moved to position 35<SP>1</SP> and the articles are lowered into a box positioned by the conveyer 32.
