Paper feeding apparatus

Abstract

Abstract PURPOSE: To feed thick paper without injury such as corrugated cardboard which is strong in the longitudinal direction and weak in the direction of thickness by constituting the apparatus so that external force is applied in the longitudinal direction of the original paper and not applied in the direction of thickness, in feeding paper. CONSTITUTION: When this paper feeding apparatus is started, a crank plate 24 is turned one time, and a kicker 5 reciprocates one time, and hangs the lowermost layer original paper 30' and pushes-out onto a front multi-opening belt 11 from under a gate 1. When the original paper 30' is pushed-out by a fixed length, a suction box 17 is allowed to communicate to a vacuum pump 31, and the belt 11 adsorbs original paper 30'. The advance speed of the kicker 5 and the circumferential speed of the belt 11 at this time are equal, and the kicker 5 is in deceleration range, so orginal paper 30' shifts onto the belt 11. The belt 11 pulls-out original paper 30' from original paper heaped-up layer through adsorption, and when the rear end of the original paper 30' reaches on the suction box 17, a valve 27 is switched, and suction stops, but the paper is conveyed as it is, for obstacle for transfer does not exist.
