摘要

PURPOSE: A feeding trolley is provided to cope with mass production of various vehicle kinds by differently adjusting the width and distance between attachments according to the vehicle kind. CONSTITUTION: A feeding trolley constitutes plural attachments on a trolley frame(1) to feed vehicle bodies. The feeding trolley comprises front right and left attachment blocks(7,9) installed to the front right and left sides of the trolley frame in a state capable of moving in the transverse direction via guide rails(3,5); front attachment width-varying units varying the width between the front right and left attachment blocks by transmitting the rotational force of a first drive motor(15) to front screw bars(13) connected to the front right and left attachment blocks via screw nuts; auxiliary frames(29) installed to the right and left sides in the rear of the trolley frame; an auxiliary frame-moving unit moving the auxiliary frame in the front and rear direction by transmitting the rotational force of a second drive motor(37) to right and left screw bars(33,35) connected to the lower parts of the sides of the auxiliary frame via screw nuts; rear right and left attachment blocks(55,57) installed to the right and left sides of the auxiliary frames in a state capable of moving in the transverse direction via guide rails(51,53); and a rear attachment width-varying unit varying the width between the rear right and left attachment blocks by transmitting the rotational force of a third drive motor(63) to rear screw bars(61) connected to the rear right and left attachment blocks via screw nuts. Attachments(10) for supporting the lower part of a vehicle body are formed to the front right and left attachment blocks.
