It is generalized to provide a V-shaped groove for guiding. In the guide-equipped conveyor belt, a guide member separately formed on the back surface of a belt body formed in a long flat plate shape is bonded in a later step. The present invention provides a method (manufacturing method) of attaching a guide member (a V guide, a tag bar, a horizontal bar, etc.) to a belt body molded into a long plate and a sticking device (manufacturing) suitably used for the method. Device). As shown in FIG. 3, a V-guide 19 is attached to the inner surface side of the belt main body 1 and a pulley (not shown) is fitted to the V-guide 19, as shown in FIG. Run without meandering. The tag bar 25 is a protrusion attached continuously or intermittently in the length direction near the side end of the outer peripheral surface (conveying surface) of the belt main body 1, and the conveyed object is the side end of the conveying belt. Prevent from falling from the part. Furthermore, in order to be able to convey a conveyed article at a steep inclination, it can also be used when attaching a horizontal rail in the width direction of the conveying surface of the belt body (not shown).

っている。2. Description of the Related Art A conventional method for manufacturing a transport belt with a guide includes processing in a factory and processing in a site where the transport belt is used. The length of the conveyor belt is individually designed for each conveyor, so even if the guide is pasted to a predetermined length in the factory and then carried in, it can be corrected at the site of use according to the length of the conveyor. Required, and a final finish in the joint processing part is required.
Therefore, the guide attaching work at the site of use is an indispensable work.

樹脂である場合に好ましく利用される。[0003] In a method of sticking in a factory, for example, a belt body is placed on a lower welder head of a high-frequency welder, a guide member is placed at a predetermined position on an upper surface (belt drive surface), and a guide member is placed thereon. An upper welder head having a groove shape corresponding to the shape (V guide shape) is pressed to operate the welder to weld them together. The belt body and the guide member are bonded at a predetermined length while being sent at the same pitch. It is preferably used when the materials of the belt body and the guide member are similar thermoplastic resins.

る。However, when a high-frequency welder or hot jet machine is used in the above factory, the guide can be continuously attached to a large number of belts, so that efficiency and quality can be stabilized. However, the size of the apparatus is large and it is difficult to carry each conveyor to the site where it is used, and it is also difficult to secure the place at many sites. The length of the conveyor and the position where the guide is attached vary depending on the design of each model, and there are many site-specific problems, requiring on-site rework. If a high-frequency welder is used in the field, a large amount of power is required and there is a problem that radio interference occurs.

A manufacturing method by on-site construction, in which a guide member separately molded with an adhesive which is a thermosetting elastic body is attached to a position where the guide member of the belt body molded in advance is attached, and
The guide member is fitted into the groove mold and clamped in a mold that can be heated to 0 to 150 ° C. and has a groove mold corresponding to the shape of the guide member, and is heated while being pressed by a simple press. By curing the adhesive, the V guide and the like are adhered to the belt main body.

It is formed in a flat strip shape by covering with soft vinyl chloride). The guide member is attached to a position of the belt body where the guide member is to be attached (the driving surface in the case of the V guide) by an adhesive which is a thermosetting elastic body. Since the bonding is performed by using an adhesive that is a thermosetting elastic body, the heating temperature can be set lower than that of the vulcanized bonding, so that the heat capacity required for bonding can be reduced. Since it is an elastic body, it can expand and contract in accordance with the bending of the running belt, and the guide member does not peel off.

着することもできる。A guide member separately molded is attached to the mounting position, and the guide member and the groove mold correspond to a mold that can be heated to 50 to 150 ° C. and has a groove mold corresponding to the shape of the guide member. Then, it is heated while pressurized by a simple press. By pressing and holding the V guide and the belt body with a mold, a thermosetting adhesive is cured and bonded while preventing displacement due to softening during heating. This temperature range can be designed by selecting an adhesive, but if it is designed to have a curing temperature of less than 50 ° C., there will be a problem of curing at room temperature in summer or the like. If the temperature is designed to exceed 150 ° C., the heat capacity required to heat the mold is too large, making it difficult to secure a heat source at the installation site. There is a problem in that the contacted portion is melted and damaged. By providing a mold having a groove shape corresponding to the shape of the guide member, the guide member can be uniformly pressed and the adhesive force can be stabilized. The V guide may be temporarily bonded to the belt main body in advance, or the V guide may be inserted into a groove of a mold, an adhesive may be applied to the upper surface thereof, and the belt main body may be placed and temporarily bonded.

To be pinched. The upper heating plate and the lower heating plate are each provided with a heating means so that the mold can be heated to a predetermined temperature (50 to 150 ° C.). The upper heat insulating material and the lower heat insulating material prevent the heat generated in the hot plate from escaping to the frame side, and prevent the upper plate and the lower airbag base from being thermally distorted. The upper plate can be moved up and down by a frame (swan neck, gate type, etc.), keeping the upper mold at a predetermined height, raising the lower mold with an air bag described later, and holding the conveyor belt between them to add Pressure is possible. The airbag base guides the lower mold, the lower heating plate, and the lower heat insulating material to be moved up and down by the airbag mounted inside and below. As the pressurizing means, a compressor, a pressurizing means such as an oil pump can also be used, for example, a high-pressure air can be guided from a pressurized air cylinder or the like to inflate the airbag,
The feature is that a pressurized air source can be easily obtained at the installation site.

ことにより特に優れた性能の搬送ベルトが得られる。When comparing the above-described embodiment with the comparative example, the durability (flexural fatigue) of comparative example D is only 200.
Cracking and rising at the V-guide portion occured after bending 10,000 times, making it unusable. However, in Examples A, B and C, only Example C cracked after 10 million bending without abnormality after 6 million bending. . In the peeling test, only Example A had a slightly poor peeling state (weak adhesive strength), but did not rise (peel) even after bending 10 million times (in Comparative Example D, it rose after bending 2 million times). Occurred). As described above, the conventional bonding method by on-site construction (Comparative Example D) bends 2 million times and cannot be used, but according to the bonding method of the present invention, it can be used up to 10 million times. In addition, a conveyance belt having particularly excellent performance can be obtained by applying the conditions of Example B.

現場に据え付けて接着作業を行うには不適当である。Although the performance of the conveyor belt obtained by Comparative Example E is excellent, it is an apparatus which is installed and processed at a specific place in a factory, and usually requires a pressurizing means such as a hydraulic machine to be large-sized. It is an unsuitable device to be installed on a narrow site where a conveyor belt is mounted to perform the bonding operation.

易にする。According to the manufacturing method of the first aspect, by using the adhesive which is a thermosetting elastic body, the curing temperature and time can be designed, and the pressing force required at the time of bonding is fixed at the bonding position. It is sufficient, and it becomes possible to cure and bond at low temperature and low pressure. As a result, the pressurizing means (such as a press) can be made small and lightweight, and the joining work at the construction site is facilitated.
