The present invention relates to a wheel conveyor constructed by installing a wheel assembly, which includes wheels and support plates arranged on both sides and rotatably supporting axles of the wheels, in a groove of a frame material, the wheel conveyor being easily disassembled and cleaned, provided with a damping function, and also provided with a dust-trapping function. Wheels have axle pins, and support plates are provided with pin holes. A wheel assembly is constructed by inserting the axle pins into the pin holes to be rotatably supported. The cross-sectional shape of a frame material is formed such that first groove-like portions formed integrally with lip portions support the support plates to be movable in the longitudinal direction. Bottom groove-like portions formed integrally with a bottom wall are formed to splay more than the edges of the lip portions. The two groove-like portions are integrally jointed to each other through a joint portion. The support plates of a plurality of the wheel assemblies are inserted along the first groove-like portions of the frame material, and a plurality of the wheels are arranged in line.

Wheel conveyor

A gravity wheel conveyor or roller conveyor is provided capable of braking for moderating and reducing the transfer speed of a relatively lightweight object being transported by using brake wheels or brake rollers, or of brake control for stopping the object being transported at a target position. In the wheel or roller conveyor that is constructed by arranging a plurality of freely rotatable wheelsor rollersin the transporting direction of an object, which transports an object being transportedby its gravitational operation, one or more selected wheelsor rollersare constructed as brake wheelsor brake rollerseach having an outer circumferential surface onto which a brake materialorthat is soft and high in its rebound resilience is fixed so as to protrude to form a diameter larger than the outer circumferential surface of each of the wheels or rollers.

In order to utilize separately steel pipe and coating resin as recycling resources, resin-coated steel pipe, which is produced by adhering a thermo-plastic coating resin on the surface of steel pipe with an adhesive, is heated by high-frequency induction heating to at least the melting temperature of the coating resin, and the coating resin is scraped off while the inner layer thereof is in a melted condition and the outer layer is in a softened condition. Coating resin and steel pipe can be recovered without the composition thereof being damaged. The scraping of coating resin is complete and efficient and requires only minimal energy since it occurs when the inner layer of the coating resin is in a melted condition and the outer layer is in a softened condition.
