JPS6475322A - Cylinder feed-in device - Google Patents

Abstract

PURPOSE:To aim at preventing cans from being damaged, and at stabilizing the feed-in thereof, in a device for feeding empty cans or the like which are closely adjacent to each other and flows down, at predetermined pitches, by specifying the shape of a curve of the rear surface of a rotary conveyer connecting between the outside of a seat arc of the rotary conveyer and the inside of the adjacent arc thereof. CONSTITUTION:A circle 22 having a radius (d) equal to the radius of a cylinder is depicted about one of points by which a pitch circle 20 having a radius (a) is equally divided into a pocket number (n) of arcs, this point serving as the center point 21 of a seating arc 13 for each pocket. Further, a chute axis 25 is drawn having an angle psi to a straight line 24 connecting between the point 21 and the center point 23 of a pitch circle 20. Then, straight lines are drawn from points P1, P2,... at which straight lines equally dividing the pitch tau by a number (m) cross the pitch circle 20, and crossing points W1, W2,... between these lines and arcs passing through points s1, s2,... by which a part of the straight line 25 between the points 27, 21 is equally divided by (m). Further, an envelope line on the side where circles having the radius (d) and having the center points W1, W2,... cross the pitch circle 20, is used as a rear surface curve 14. With this arrangement, it is possible to prevent cans from being damaged.
