DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for retracting a conveyor belt or a pipe conveyor belt, and more particularly, to a method for rolling a conveyor belt or a conveyor belt into a hollow cylindrical shape by transporting the conveyor belt or a pipe conveyor belt with a holding roller. The present invention relates to a method for pulling in a conveyor belt or a pipe conveyor belt to be drawn into and laid on a frame composed of a support base.

[0002]

2. Description of the Related Art Conventionally, as a mechanism for transporting various conveyed goods in large quantities, transportation by a conveyor belt connecting endlessly between pulleys has been known. FIG. 4 (a) shows that the conveyor belt is successively drawn into and laid on a frame composed of a holding roller and a support table, and is replaced.
And (b). However, since the conveyor belt pull-in fitting protrudes from the surface of the conveyor belt in a convex shape, it is easily caught by the frame consisting of the holding roller and the support base, increasing the pull-in resistance of the conveyor belt and removing the paint when the pull-in fitting contacts the equipment. There were times. Therefore, repair work is indispensable after the completion of the replacement work, and the number of man-hours is increased. In addition, the frame made up of the holding roller and the support table is damaged, and the durability and the appearance are deteriorated.

[0003] On the other hand, there is known a pipe conveyor in which a conveyor belt is rolled into a pipe shape and transported to reduce scattering of powdery or granular materials to the outside. At the time of new installation or replacement of the pipe conveyor belt, at the time of repair, by successively pulling and laying the conveyor belt on holding rollers installed in a hollow circular shape,
The conveyor belt is rolled into a pipe shape. However, because the conveyor belt is drawn into a curved line while deforming it into a pipe shape, the ears and pull-in fittings of the conveyor belt are easily caught by holding rollers, etc., so that the pull-in resistance of the conveyor belt is increased or the equipment is peeled off. As a result, repair work is indispensable and the number of man-hours is increased. In addition, the frame made up of the holding roller and the support is damaged, and the durability and the appearance are deteriorated.

Therefore, as shown in Japanese Patent Application Laid-Open No. H5-4707, a method in which the retraction portion is restrained in a pipe shape by a restraining means such as a string or a polyethylene band for temporary fixing, and the inside of the holding roller 2 is sequentially drawn and laid by a wire. Is proposed,
The effect of reducing the retraction force to some extent was recognized. However, the conveyor belt is not familiar with the pipe shape, and the restraining means itself for temporary fixing is easily caught by holding rollers, etc., which increases the resistance of the conveyor belt to pull in and removes the painting of equipment, so repair work is required. Indispensable, the number of man-hours also increased, and furthermore, the frame composed of the holding roller and the support table was damaged, and this also became a cause of deterioration in durability and appearance.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. The present invention is directed to a conveyor belt or a pipe conveyor belt which is rolled into a hollow cylindrical shape and transported by holding rollers or supporting rollers. Concerning the method of pulling in a conveyor belt to be drawn into and laid on a frame consisting of a stand, while reducing the pull-in resistance of the conveyor belt or the pipe conveyor belt, the fittings of the conveyor belt or the pipe conveyor belt are caught by the frame consisting of the holding roller and the support base. Another object of the present invention is to provide a method for retracting a conveyor belt or a pipe conveyor belt, which reduces the possibility of peeling off the coating of the equipment.

[0006]

According to the present invention, there is provided a method for retracting a conveyor belt, wherein a metal fitting for retracting the conveyor belt is attached to the conveyor belt, and the conveyor belt is retracted and laid on a frame having holding rollers and a support base. Provided is a method for retracting a conveyor belt in which a retractable member is protected on at least one side by a flexible member.

Accordingly, even when the conveyor belt is pulled in with no restriction wire, at least the pulley side of the conveyor belt pull-in is protected by a member made of a flexible material. The possibility of direct contact with the frame consisting of the holding roller and the support base is reduced, the conveyor belt is hard to be caught, the pull-in resistance of the conveyor belt is reduced, and the paint on the equipment can be prevented from being peeled off.
Moreover, the durability and appearance of the frame and the holding roller can be improved.

According to another aspect of the present invention, a pipe conveyor belt is formed by rolling a conveyor belt into a pipe shape, forming a hollow cylindrical shape, attaching a metal fitting for pulling in the conveyor belt, and pulling it into a frame including a holding roller and a support base. A method of retracting a conveyor belt, wherein an outer surface of the retractable metal fitting is protected by a flexible member and inserted into the frame and the holding roller.

By doing so, when the conveyor belt is drawn into a curved line while being deformed into a pipe shape, the outer surface of the metal fitting for the pipe conveyor belt is protected by a member made of a flexible material. The danger of the metal fitting directly contacting the roller is reduced, and the durability and appearance can be improved. In addition, the frame and the holding roller are less likely to be caught, and the pull-in resistance of the conveyor belt can be reduced.

According to another aspect of the present invention, there is provided a method for retracting a conveyor belt or a pipe conveyor belt, wherein the flexible member for protecting the retractable metal fitting is made of a conveyor belt or a pipe conveyor belt. This not only enables the reuse of used conveyor belts or pipe conveyor belts that have only been conventionally discarded, but also reduces the consumption of the conveyor belt or pipe conveyor belt equipment itself, thereby maintaining good maintenance. Management becomes possible.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The retraction method for a conveyor belt or a pipe conveyor belt according to the present invention comprises a holding roller and a support table while protecting the surface of the retraction metal fitting for the conveyor belt or the pipe conveyor belt with a member made of a flexible material.

[0017]

[Table 1]

As a result, it has been confirmed that by employing the conveyor belt retracting method of the present invention, the number of repairs can be reduced by 85%, the necessity of the repair is reduced, and the work efficiency is remarkably improved. Was.

[0019]

According to the present invention, when the conveyor belt or the pipe conveyor belt is drawn into the frame composed of the holding roller and the support base and laid as described above, the surface of the pull-in fitting for the conveyor belt or the pipe conveyor belt is made of a flexible material. Since the member is inserted while being protected by such a member, the pull-in resistance of the conveyor belt or the pipe conveyor belt can be significantly reduced. In addition, the contact of the conveyor belt or pipe conveyor belt pull-in fittings reduces the likelihood of peeling off the coating on the frame and holding roller, further reducing damage to the frame and holding roller, reducing the need for repairs and significantly improving work efficiency. did.
