Abstract
An endless conveyor system includes movable lift rails for supporting the conveyed articles on either side of an endless conveying member. The lift rails are defined by end-to-end sections with adjacent ends of adjacent sections simultaneously movable between a lowered position wherein the articles may be engaged by the conveying member and a raised position wherein the articles are lifted above and out of engagement with the conveying members for interrupting the advancement of the articles with zero back-pressure.
Claims15
A zero back-pressure conveyor system of the type having a movable member for advancing articles;
- and a lift rail adjacent to the movable member for supporting the articles, the lift rail further comprising:
- a. a first section having opposite ends;
- b. a second section adjacent to the first section and in longitudinal alignment therewith, having opposite ends, wherein one end of the first section is adjacent to and in alignment with the one end of the second section;
- c. a coupler connecting the adjacent ends of the first and second sections for defining linked ends, the coupler be pivotally mounted on one of said ends and fixedly secured to the other of said ends;
- and
- d. an actuator connected to one of said sections adjacent to said linked ends and adapted for raising and lowering the linked ends relative to the movable member.
A zero back-pressure conveyor system of the type having a endless element mounted on a support frame and movable for advancing articles in a desired direction along a path, and a lift rail along a side of the movable element for supporting the articles, the lift rail comprising a plurality of end-to-end sections having opposite ends, with adjacent ends of the end-to-end sections placed in juxtaposition with one another, the system further comprising:
- a. an actuator mechanism attached to said adjacent ends for simultaneously raising and lowering said adjacent ends of said adjacent end-to-end sections for lowering and raising said adjacent ends relative to said endless member.
