ABSTRACT:
An automatic apparatus for supplying flattened cardboard boxes or work units to an automatic packing machine. The apparatus comprises a first belt conveyor on which the work units are placed groupwise in a standing posture closely in contact with each other, a second belt conveyor onto which the work units on the first are transferred while maintaining them upright, a holding bracket slippingly disposed on the first belt conveyor, and retaining means provided at the juncture of the first and second belt conveyors. The holding bracket is adapted to be borne by friction so as to hold and push the work units upright in close contact and to slip on the first conveyor belt owing to the reaction from the work. The retaining means comprises two holding pins which are kept retracted under the belts until the work has been completely transferred onto the second belt conveyor and then project above the belt conveyor so as to hold the work units from the rear to prevent them from falling backward.
