Abstract
A colored resin molder having a cylindrical input member, a resin material supply mechanism for storing a molding resin material having thermoplastic properties and supplying the stored resin material through the input member, a coloring agent supply device having a nozzle discharge end disposed in the input member for supplying a liquid coloring agent, a feeding mechanism for feeding the resin material from the resin material supply mechanism while mixing the coloring agent with the resin material for resin molding, a sensor device for detecting the status of the feeding by the feeding mechanism, and a control unit for controlling the operation of the coloring agent supply device according to the result of the detection by the sensor device.
Claims4
A colored resin molder comprising:
- an input member;
- material resin supply means for storing a resin material having thermoplastic properties and supplying the stored resin material through said input member;
- coloring agent supply means having a nozzle discharge end disposed in said input member for supplying a liquid coloring agent;
- feeding means for feeding the resin material from said resin material supply means while mixing the coloring agent with the resin material for resin molding;
- sensor means for detecting the status of feeding by said feeding means;
- and
- control means for controlling the operation of said coloring agent supply means according to the result of detection by said sensor means by providing a suction force to said nozzle discharge end of said coloring agent supply means when said sensor means detects a stationary state of said feeding means.
