Patent ID: 6852008

Claim:
A method for discharging works from a centerless grinder, wherein said works are through-fed to said centerless grinder, processed with grinding therein, aligned axially along a horizontal direction on a guide plate disposed at a discharging side of said centerless grinder, and pushed from a front end of said guide plate by means of a thrust force provided during the grinding, whereby said works are caused to fall, by means of their own weight onto a discharge chute disposed therebelow which comprises: (a) pressing downward vertically on an upper end of the circumferential surface of a preceding work of said works being pushed from said guide plate by means of a roller energized with a spring, and (b) causing said preceding work that has been completely pushed from said guide plate to fall, while bringing the front end of said preceding work that has been completely pushed from said guide plate into contact with a contact surface of a stopper that hangs in front of said front end of said guide plate, swingable in the direction of said works being pushed out, wherein said stopper is arranged to have the contact surface positioned in the same vertical plane as the front surface of the preceding work that has been completely pushed from said guide plate through an arm extending in the vertical direction from the contact surface to be swingably pivoted on the upper end of a bracket, whereby said stopper makes no swinging motion in the case where only said preceding work has been completely pushed from said front end of said guide plate, and said stopper makes a swinging motion in the case where one following work of said works, that is immediately following said preceding work is pushed from said front end of said guide plate together with said preceding work so that said following work is prevented from being pushed out together with said preceding work by a horizontal component force caused by said swinging motion.
