Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polymerization belt conveyor in which an object to be conveyed is sandwiched between two superimposed belts and conveyed from below to above or vice versa. The present invention relates to an edge roller mounting structure that can easily perform an operation of adjusting an edge roller that comes into contact with a surface.

[0002]

2. Description of the Related Art A conveyed object having various properties, such as a lump of ore or limestone, a granular material such as beans, a powder of sugar or flour, etc., is sandwiched between two belts to move up and down. A so-called polymerization belt conveyor for conveying in a direction is known. In this polymerization belt conveyor, a large tension is applied to two belts as compared with a normal belt conveyor, and the conveyed objects are held by a force of the belts trying to adhere to each other.

[0003] Carrier rollers are disposed in each of the horizontal transport sections arranged vertically and in a loop transport section connecting each horizontal transport section and the vertical transport section, and one roller or two superposed belts are arranged by the rollers. I support. Further, a plurality of edge rollers are arranged in the vertical transport section, and the rollers are supported by contacting the non-transport surface on both ends in the width direction of the two superposed belts.

The edge rollers are staggered with respect to the non-conveying surfaces of the belts so that the paths of the conveying surfaces of the two belts (surfaces that oppose each other and sandwich the conveyed object) in the vertical conveying section are straight. And are in contact with each other. For this reason, when the abrasion of the belt grows, the edge roller is separated from the belt, and sufficient support cannot be realized. In this case, an adjustment is made so that each edge roller comes into contact with the non-conveying surface of the belt.

The number of the edge rollers is large (approximately 240 when the height of the vertical portion is 15 m), and there is a problem that it takes time to adjust these edge rollers so as to contact the belt. To solve this problem, a technique disclosed in Japanese Utility Model Laid-Open No. 5-42967 has been proposed. In this technique, a pair of parallel frames to which rollers are attached are provided, and the frames are moved relative to each other in opposite directions so that the rollers contact the belt simultaneously.

[0006]

However, in the above technique, when a new belt is used, each roller abuts on the belt at substantially equal intervals in the belt transport direction.
If an attempt is made to adjust in the event of wear, a problem arises in that the roller spacing along the transport direction of the belt varies. And if the belt is not evenly supported,
This poses a problem that the transferred object may leak from a portion where the two belts overlap.

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the time required for adjusting an edge roller against a belt, and to maintain an interval between rollers even when the adjustment is caused by abrasion of the belt. It is to provide a structure.

[0008]

In order to solve the above-mentioned problems, a typical edge roller mounting structure of a polymerization belt conveyor according to the present invention includes a lower horizontal portion (lower horizontal transport portion) and a vertical portion (vertical transport portion). An overlapping horizontal belt (upper horizontal transporting section) having two upper belts stretched over the respective transporting sections and transporting the transported object in the vertical direction. A pair of long plates are arranged to face each other along the transport direction on both sides in the width direction of the overlapped belts, and can be rotated by a center pin at least at three opposing positions of each long plate. The two link plates connected to the long plate are rotatably mounted on the long plate, and the center pin is rotatably mounted on the apparatus frame at two of the three positions. In some places, the center pin is attached to an adjusting member provided on the apparatus frame, and furthermore, abuts against the non-conveying surface of each belt at the widthwise ends of the two belts transferred to the long plate. It is configured by attaching a plurality of edge rollers.

In the edge roller mounting structure, the two link plates mounted on the long plate are rotatably mounted on the fixed fulcrum of the apparatus frame, and the other one is provided on the apparatus frame. Since it is attached to the adjusting member, by operating the adjusting member, the pair of long plates can be moved only in a direction away from or approaching each other without causing relative movement in the longitudinal direction.

Therefore, the edge rollers attached to the pair of long plates in a staggered manner can be separated and approached without changing the pitch, and the edge rollers at the widthwise ends of the two superposed belts can be separated. The non-transport surface (the back surface of the transport surface) can be uniformly contacted.
