Title:
TAKE-UP DEVICE FOR WIRE PULL CONVEYOR
Document Type and Number:
Japanese Patent JP2950471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To hold required tension constant regardless of the state of load so as to stably convey the load without causing over-flexure or applying over- tension.
SOLUTION: This wire pull conveyor is so constituted that a conveyor body 4 with a wire rope fitted to both side end parts of a conveyor belt is endlessly stretched over a driving pulley 3 provided at a head part, and a driven pulley provided at a tail part and that a plurality of intermediate supports 5 for supporting the conveyor body 4 are provided between the driving pulley 3 of the head part and the driven pulley of the tail part. In this case, the head part provided with the driving pulley 3 is provided with a take-up pulley 7 and a turn-around pulley 8, and the return path side of the conveyor body 4 is stretched over the take-up pulley 7 and the turn-around pulley 8. A load cell 14 for detecting the tension of the conveyor body 4, and a hydraulic jack 13 expanded/contracted on the basis of the detected value of the load cell 14 to move the take-up pulley 7, are provided to automatically move the take-up pulley 7 so as to make the tension of the conveyor body 4 constant.
