Machine for feeding waterproof seal members for electric wires, method for fitting waterproof seal members over electric wires and apparatus for processing electric wires

摘要

A waterproof seal feeding machine (100, 200, 300, 400, 500) is provided to feed waterproof cylindrical seal members (2) to a predetermined fitting position (P) defined on an axis line (L) of an electric wire (W) to fit the seal members (2) onto outer peripheries of end portions of the electric wire (W). The waterproof seal feeding machine includes a holder pair (41U, 41L; 71U, 71L) which open and close at the fitting position. The waterproof seal feeding machine further includes a seal cavity defining member (40, 70) which receives the seal member (2) in a seal cavity (41b) at the fitting position (P) when the holder pair (41U, 41L; 71U, 71L) are moved toward each other to a closed state, a passage forming member (20, 60, 90, 110) which forms a feeding passage (22, 62, 92, 111) to feed the seal member (2) into the seal cavity (41b) with such a posture as to receive the electric wire (W) by the compressed air, a locking mechanism (38, 87) which reciprocatably brings the seal member (2) to a locked state in cooperation with the holder pair (41U, 41L; 71U, 71L) of the seal cavity defining member (40, 70) and releases the locked state after insertion of the electric wire (W), and a control unit (600) which controls the overall operation of these elements.
