摘要:
Apparatus is disclosed for removing a coating from synthetic resin products, such as an automobile bumper, to obtain improved coating removal rate and improved productivity. A resin material (Wb) having a coating (Wc) applied thereto is rolled between a resin-side roll (11) and a coating-side roll (12) which rotate at different peripheral speeds. A shear stress is applied to the interface between the resin material (Wb) and the coating (Wc), thereby removing the coating from the resin material. Pressing means (41) press the coating-side roll (12) towards the resin-side roll (11) with a predetermined force. The resin-side roll (11) and the coating-side roll (12) apply a normally fixed shear stress between the resin material (Wb) and the coating (Wc), ensuring stable coating removal and improved productivity.

A safety device is provided for a film removing and peeling apparatus, which rolls a coated resin member between a pair of rolls (11,12) facing each other and rotating at different peripheral rotating speeds and which applies a shearing stress between the resin material and a film to peel the film from the resin material. The safely device includes: a flat plate (21) to which a resin material is fed, the flat plate being provided so as to extend in a substantially horizontal direction at a height substantially corresponding to a gap between the rolls, and the flat plate having a front edge (21a) located so as to be close to the rolls; a pushing plate (23) for pushing the flat plate to squeeze the resin material into the gap between the rolls; and an air cylinder (22) for moving the pushing plate in a forward direction to cause the pushing plate to push the flat plate.

A coated film is peeled and removed from a resin product by rollers. Each roller has a different rotational speed and applies a shear slipping stress between the coated film and the resin material to peel the coated film from the resin material. The apparatus includes cooling means for cooling one of the rollers by feeding coolant through a passage formed in the roller so as to reduce adhering the coated film to the roller surface.

A coated film peeling/removing apparatus for a coated resin product includes a protruded portion shearing device for shearing and removing a protruded portion of the coated resin product, an end part treating device for rolling a coated resin product so as to modify the sectional contour such that the coated film side becomes a short side relative to the resin raw material side, and upper and lower surface coated film peeling devices for peeling and removing the coated film from the resin product by applying a shear slipping stress between the resin product and the coated film.

摘要:
A film peeling and removing apparatus is provided for peeling or removing a film from a resin material of a coated resin member of a coated resin product. The film peeling apparatus includes a resin-material-side roll, a film-side roll and a third roll. The film-side roll rotates at a higher peripheral speed than that of the resin-material-side roll. The film-side roll is associated with the resin-material-side roll for rolling the coated resin member therebetween while applying a shearing stress between the film and the resin material so as to peel the film from the resin material. Then, the resin material is fed between the resin-material-side roll and the third roll while being curved along the roll surface of the resin-material-roll. The third roll is associated with the resin-material-side roll for rolling the fed resin material therebetween while applying a shearing stress between a residual film and the resin material so as to peel the residual film from the resin material.
