Embodiment Construction

[0015] Figure 1 illustrates a conveyor 10 embodying features of the present invention that includes a conveyor belt 12, such as a modular roller overhead conveyor belt. The conveyor belt shown is a modular conveyor belt made up of belt modules 14 arranged in a series of rows 16 . The rows are connected together by hinge pins 17 at hinge joints 18 which allow the belt to articulate about drive and tension sprockets 20 on each end of the conveyor. The belt forms an endless loop that moves about a drive shaft 22 and an idler shaft 24 . The shaft is supported at its ends in bearing housings 26 mounted on the conveyor frame (not shown for clarity). A motor 28 is connected to the drive shaft 22 to drive the belt. As the output shaft 30 of the motor rotates as indicated by arrow 32 , the belt advances in a belt travel direction 34 .

[0016] A portion of the belt loop (in particular the upper, article conveying portion 36 in FIG. 1 ) is supported on a conveying path 38 ( FIG. 2 )....

Abstract

A conveyor (10) using a roller belt (12) with rollers (42) arranged to rotate on oblique axes (44) to urge articles toward a side guide (54) . The conveyor includes an oblique-roller belt (12) supported on a carryway (38) . Rollers (42) extend above an outer conveying surface of the belt without contacting the carryway. Each roller rotates on an axis (44) oblique to the direction of belt travel and interesects the side guide (54) downstream of the roller. A retractable stop (60) is movable to and from a blocking position along the carryway. In the blocking position, the stop blocks the conveyed articles from advancing in the direction of belt travel . The rollers underlying the blocked articles rotate as the belt runs by contact with the articles. The rotating rollers provide a force to the blocked articles directed toward the side guide (54) to push the articles against the side guide or other articles as they accumulate upstream of the stop .

Description

Background technique [0001] The present invention relates to power driven conveyors, and more particularly to a conveyor that accumulates and moves items across the conveyor using a conveyor belt with obliquely oriented rollers. [0002] Many material handling applications require the accumulation and alignment of conveyed items into single rows or groups for subsequent processing or inspection purposes. One method of arranging items in a single file against one side of a conveyor is to use a conveyor belt that has rollers with protrusions that protrude beyond the top and bottom surfaces of the belt. As the belt advances in the direction of belt travel, the rollers rotate on bearing surfaces below the belt bottom surface. The drum is arranged to rotate about an axis oblique to the direction of movement of the belt. Rotation of the drum on its inclined axis provides a lateral force component that directs the items conveyed on top of the drum toward the side with side guides. ...
