Problems solved by technology

[0009] However, in the above-mentioned method, the equipment for two-color molding is required, the mold mechanism is complicated due to the secondary molding, and the productivity is poor, and the resin forming the shaft portion has adhesiveness with the elastic body. There are many problems such as mold processing and molding are difficult due to the uneven shape of the resin, and the current situation is that there is no cost reduction even if there is no manual assembly process

Embodiment Construction

[0059] The conveying roller transported by the present invention is characterized in that the conveying roller is configured at least by a resin shaft portion and a elastomeric portion conveying the conveyed substance, and the shaft portion is melt engaged in the elastomeric portion. This feature is a common or corresponding technical feature in the following embodiments.

[0060] As an embodiment of the present invention, the elastomeric portion contains a thermoplastic elastomer from the viewpoint of reflecting the effects of the present invention, which is preferred from the viewpoint of shaping the elastomeric portion by injection molding.

[0061] Further, from the viewpoint of integrally forming the shaft portion and the axis elastomeric portion, it is preferable that the resin material containing the shaft portion and a resin of a thermoplastic elastomer containing the elastomeric portion The absolute value of the value of the solubility parameter of the material is within ...

Abstract

The present invention addresses the problem of providing: a low-cost and high-precision resin conveyance roller that does not require manual assembly of an elastic member; and a method for manufacturing the same. The conveying roller is used for conveying an object to be conveyed, and is characterized in that the conveying roller is composed of at least a shaft part made of resin and an elastic body part for conveying the object to be conveyed, and the shaft part and the elastic body part are fused and bonded.

Description

FIELD [0001] The present invention relates to a conveying roller and a manufacturing method, and more particularly, relates to transporting the elastomeric member does not need to manually assemble and inexpensive and highly accurate resin by a roll and a manufacturing method. Background technique [0002] Rollers for conveying paper for laser printers, multifunction machine, etc., and become elastic body for holding the paper, the roller portion of the paper out, driving transfer structure of the gear unit and the rotation shaft are combined, multiple number of parts, assembling man-hour consumption also becomes a factor of cost increase. [0003] figure 1 It is a schematic view of a conventional conveyor has a shaft portion made of a metal with a roller. [0004] Conveying roller 1 made of a metal with a metal shaft portion (also referred to as a shaft) 2, out of the roller unit 3, the tubular portion of the elastic member 4, a gear unit 5 constituting the elastic body 4 of of...
