445,824. Manufacturing paper containers. JAGENBERG-WERKE AKT.-GES., 107, Himmelgeisterstrasse, D³sseldorf, Germany. Nov. 19, 1935, No. 32024. Convention date, Nov. 20, 1934. [Class 18] Paper containers with a glued longitudinal seam and enlarged at the top, made, e.g. from blanks m, Fig. 1, and ends b on rotating formers d, are kept nested in a magazine T which applies pressure to the seam N, Fig. 5, until the glued joint is consolidated, after which the container is withdrawn for further treatment. The containers may be blown into a pipe r by compressed air and removed by grippers which deposit them in cells z of a chain k. The pile S of containers resting on a plate e, Figs. 3 and 5, is gripped by strips 13 with rubber coatings g carried by a fixed support 8, Fig. 5, a spring-actuated lever 10 hinged to the support 8 and controlled by a roller 12 on a lever 6, Fig. 2. mounted on a shaft 1, also carrying a presser strip 13. A cam 5 on a shaft 4 actuates a lever 2 on shaft 1 to control lever 6 to grip and release the containers. The containers are kept from falling out by a stop 16 carried on one arm of a lever 15 the other arm of which carries a roller 17 actuated by a cam 18 on shaft 4. Gripping the containers. A further cam on shaft 4 controls an oscillating arm 20, Fig. 2, by a connecting rod 22, a lever 23, and a roller 24. The spring gripper 21 is carried by arm 20 and is opened by moving a lever 25 by cams 26b, 26a on a lever 27 pivoted on a shaft 14 and controlled by a cam 29 on shaft 4 which contacts a roller 28. The gripper is closed when released from can 26a by a spring (not shown). The timing is such that stop 16 moves aside in time to allow gripper 21 to grip the lowermost container, the penultimate container being gripped by the pressers 13. When the gripper has withdrawn, carrying the container, stop 16 moves upward and lever 6 is actuated to release the pressers 13 so that the pile slides down to the stop, the pressers then again coming into action. The gripper conveys the container to a cell z of a chain k, and is opened by cam 26b and thereafter swings back through the next vacant cell of the chain. Meanwhile cams 26a, 26b move down so that the gripper is opened by cam 26a preparatory to the next cycle. Adjusting the length of the stack. If the stack becomes so short that the time the container is in it is inadequate for the consolidating of the glued seam, a feeler F, Fig. 7, no longer contacts a container and moves to actuate a ratchet 32 by a lever 30 and spring 31, so that a rod 33 on lever 27 is inhibited from movement by the ratchet 32 and the movement of the gripper is stopped until accumulation of containers in the stack releases feeler F and the ratchet 32 is withdrawn by spring 31. |
