Abstract
A modular conveyor particularly adapted for food processing installations including a plurality of pedestals arranged along a single line and removably connected to a plurality of aligned beams and laterally-spaced side rails to support a plurality of belt-supporting rollers. The conveyor can be adjusted to a cleaning position where the conveyor belt is opened for interior cleaning while still permitting the belt to be driven by its usual driving mechanism.
Claims4
A conveyor comprising
- a. a frame,
- b. a drive roller mounted at one end of the frame,
- c. a driven roller mounted at the other end of the frame movable toward the drive roller,
- d. a belt entrained over said rollers for conveying material,
- e. incremental adjusting means for moving the driven roller toward the drive roller by an incremental distance to shorten the length of the belt path by a predetermined distance, and
- f. a plurality of support rollers supporting the top course of the belt, and elevational adjusting means for moving at least one of said support rollers to an elevated position increasing the length of the belt path by a distance equal to said predetermined distance and for lifting the belt clear of said non-elevated support rollers while maintaining it in driving contact with said drive and driven rollers whereby easy access for cleaning is thereby provided, the elevational adjusting means for said one support roller including a pair of arms connected at one end to said roller and pivotally connected at the other end to said frame for pivotal motion in the direction of travel of the upper belt course and through an angle between 90 degrees and 135 degrees whereby the pressure exerted by the belt retains said one support roller in its elevated position.
