Abstract
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.
Claims9
A system for recycling of a resin product coated with a film, comprising:
- shearing means for removing a protruding portion from said resin product by crushing said resin product between a first pair of rollers and for making a plurality of resin product strips;
- first transferring means for receiving said resin product strips and for flatting thereof including a first plurality of pairs of rollers rotated at first different speeds with respect to each other in order to flatten said resin product strip;
- edge forming means for making a trapezoid cross-sectional shape of said resin product strip including a second pair of rollers for producing a trapezoidal shaped resin product;
- second transferring means for receiving said trapezoidal shaped resin product strip including a second plurality of pairs of rollers;
- and
- film removing means for separating said film from said trapezoidal shaped resin product strip by giving a sheer stress therebetween including a third pair of rollers rotated at second different speeds with respect to each other.
A recycling method of a resin product coated with a film, comprising the steps of:
- removing a protruding portion from said resin product by crushing thereof between a first pair of rollers;
- flattening said resin product by moving said resin product through a first plurality of pairs of rollers rotated at first different speeds with respect to each other in order to flatten said resin product;
- making a trapezoidal cross-sectional shape of said resin product by passing said resin product through a second pair of rollers;
- transferring said resin product to a next step by moving said resin product through second plurality of pairs of rollers;
- and
- separating a film from said resin product by giving a sheer stress therebetween through a third pair of rollers rotated at second different speeds with respect to each other.
