DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt feeding / feeding apparatus, and more particularly, to a belt set obtained by cutting a belt sleeve and attaching the belt group to a belt installation portion attached to a ring-shaped rotating body, and then setting the rotating body to a belt set. From the position to the belt feeding position, the belt group attached to the belt setting part is moved in parallel by a predetermined pitch, sent out to the belt standby position, and the belt is pinched by the picking part of the conveying part and moved in the multi-axial direction. The present invention relates to a belt supply feeding device having the same.

2. Description of the Related Art Heretofore, when a transmission belt is attached to or removed from a driving pulley to which a fixed transmission belt is fixed and a movable tension pulley, an operator manually performs these belts manually. However, recently, the length of a low-edge V-belt cut into a V-shape from a belt sleeve is inspected, and if the measured value is within the allowable range, the side of the belt is polished with a grinder to correct the length and finish the finished product. As the machine and the belt winding machine have been automated, the attachment of the power transmission belt to the pulley has been improved in various ways.

[0003] For example, as disclosed in Japanese Patent Publication No. 1-24303, a driving pulley and a tension pulley are mounted on a fixed shaft and a moving shaft, respectively, and a belt is formed by hanging a belt over these pulleys. In the apparatus, when attaching a belt to a pulley, a plurality of (four) bar hangers are fixed to a vertically rotatable support, and the hanger to which the belt group is attached is turned to move to a belt feeding position. Then, the belt group was fed at a constant pitch and moved to the standby position at the front end. When all the belts disappeared, the belt installation section was turned by 90 ° and the belt was fed by the same operation.

[0004]

However, in the conventional belt feeding / feeding device, a plurality of bar hangers are mounted concentrically and horizontally on columns arranged vertically, so that the entire device becomes large and a large space is secured. Need to
For this reason, if the length of the hanger is shortened, the belts attached to the adjacent hangers come into contact with each other and interfere with each other, so that the belt may ride on another belt, and the belt may not be properly arranged. Further, since the protruded hanger is turned, this turning area is extremely dangerous to the operator.

An object of the present invention is to improve such a problem, and an object of the present invention is to provide a belt feeding / feeding apparatus in which the entire apparatus is reduced in size and safety is ensured.

A belt setting unit for attaching the group, a belt feeding mechanism for moving the belt group attached to the belt setting unit in parallel by a predetermined pitch and sending the belt group to a belt standby position, and a conveying unit for moving a knob for holding the belt in a multiaxial direction. , A belt supply and feeding device. In this device, since the rotating body is arranged to pivot on the vertical plane by a predetermined angle about the support shaft, the entire device can be downsized and safety can be ensured.

According to a second aspect of the present invention, there is provided a belt feeding / feeding device in which a hanger of a belt installation portion is provided with a semi-ring shaped stopper at a rear end thereof for preventing reverse movement of the belt group. Is provided, the belt group can be accurately arranged from the set position to the feeding position, and the belt group can be moved in parallel by a predetermined pitch and sent out to the belt standby position.

In the invention according to claim 3 of the present application, the belt standby position provided at the tip of the hanger of the belt installation portion is a pair of a continuous arrangement of an inclined surface, a concave belt storage portion, and a stopper protruding upward. This is a belt feeding and feeding device in which plate-like members are arranged in parallel at intervals, and can be stably installed without dropping the belt, and can securely grip and pick up the belt.

In the invention according to claim 4 of the present application, the push plate having the vertical moving means by which the belt feeding mechanism can approach the belt setting portion, and the belt is moved by moving the push plate along the longitudinal direction of the belt setting portion. The belt feeding and feeding device includes a horizontal moving means for feeding a group at a predetermined pitch.

[0010] In the invention according to claim 5 of the present application, the transport section comprises a knob section for holding the belt and moving means for transporting the knob section in three axial directions.
