Title:
DRIVE CONTROLLER IN ACCUMULATION CONVEYOR
Document Type and Number:
Japanese Patent JP3460057
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a drive controller capable of simplifying a control mechanism for a conveying roller which forms a conveying passage.
SOLUTION: At the bottom part of a retaining frame 1 which is rotatably supported by a support shaft 17 in a vertical direction, has at its top part a control member 18 interposed between a pair of adjacent conveying rollers and has therein a drive leap 2 rotated by a drive source, an operation part 34 having a cap 32 swelled by pressurized air is provided. At swelling of the cap 32, the retaining frame 1 is lifted, and the drive leap 2 is brought into pressure contact with a pair of adjacent conveying rollers. At disappearance of the swelling of the cap 32, the retaining frame 1 is rotated downward by its self weight, and with an inclination produced by this downward rotation, a side edge of the control member 18 is brought into pressure contact with one of the conveying rollers, whereby the rotation is controlled.
