その他のコスト増を避けることができない。If a conveyor belt such as a timing belt, ■ belt, or flat belt does not have a profile on its conveyor surface (the side that does not come into contact with the driving and driven pulleys), the conveyed object will slide on this surface, resulting in inaccurate Transport cannot be performed. On the other hand, in the case of a belt with a profile, accurate conveyance is ensured by the action of the profile, but
Not only does this profile not have the versatility to adapt to all shapes and sizes of objects to be conveyed, but the profile must be molded integrally with the belt body, making it possible to avoid increased mold costs and other costs. Can not.

提供される。In the conveyor belt according to the present invention, by providing a polyurethane rubber layer having a lower hardness than the polyurethane rubber forming the belt body on the conveying surface side of the polyurethane rubber belt, manufacturing costs can be reduced, and the shape and size of the conveyed object can be reduced. Provided is a belt that ensures accurate conveyance without being restricted by.

にするためである。The polyurethane rubber layer, which has a lower hardness than the polyurethane rubber that forms the belt main body, is a coating with a J Engineering SA hardness of about 40 to 80 on the conveying surface of a polyurethane rubber belt manufactured by injection molding, extrusion molding, casting, etc. A solution of dimethylformamide, methyl ethyl ketone, or a mixed solvent thereof (concentration of about 5 to 25%) for the polyurethane to be formed is applied with a brush, knife, spatula, etc., and this is applied with a hot plaster at a temperature of about 100 to 150°C for about 50 minutes. It is formed by drying for about 15 minutes or about 5 to 30 minutes in an electric furnace at a temperature of about 100 to 120°C. Note that the JISA hardness is limited to a range of 40 to 80, which is lower than the urethane hardness (approximately 80 to 95) used for ordinary belts and higher than the lowest urethane hardness (approximately 40). This is to do so.

の接着強度がそこに得られている。This polyurethane rubber layer has a thickness of about 0.001 to 1 mm, and generally about 6 to 100 mm, depending on the width of the belt.
They are provided intermittently with a width of approximately 1 to 15 m in length. This intermittent interval is about 5 baskets for small intervals, while for large intervals it is about 600 to 1000 belt lengths.
There may be one location per a, and it is selected as appropriate depending on the purpose of use. The polyurethane rubber layer provided in this way can be easily formed on-site to match the shape and size of the conveyed object, and moreover, the polyurethane rubber layer made of the same material as the belt body is applied there as a solution. The polyurethane rubber layer is firmly adhered to the Hubbert body by the action of the solvent. That is, when this type of coating is formed using an adhesive, the adhesive strength is about 10 or less, but in the case of the present invention, the adhesive strength is about 30 or more. It has been obtained.

という効果を奏する。The conveyance belt according to the present invention is provided with a polyurethane rubber layer having a lower hardness than the polyurethane rubber forming the belt body on the conveyance surface side, so that the conveyed object may not be conveyed on the conveyor belt or the conveyance may be uneven. This has the effect of always ensuring accurate conveyance conditions, without causing the conveyed objects to slip, collide with each other, and cause damage.
