Abstract
An electric capping machine for crimping the caps of containers, in which each cycle of operation takes place fully automatically, once initiated by the operator; in the course of each operation, a container-receiving member is automatically raised into engagement with a spring-loaded abutment roller of the crimping mechanism which, upon further upward movement, causes the crimping roller to be positively brought into engagement with the edge of the cap by the use of a quadrilateral linkage connection actuated by a cam follower; to increase the safety to the operating personnel, both hands must be placed in a predetermined position relative to the machine before the cycle of operation can be initiated.
Claims38
A capping machine for crimping the caps of containers, which is operable to carry out automatically one complete cycle of operation, once initiated by an operator, comprising housing means, container-receiving platform means, drive means including first means for rotating said platform means and second means for controllably raising and lowering said platform means in timed relation to the operating cycle, and a crimping mechanism above the platform means and operable to engage the cap of a container on the platform means when being raised and rotated by said drive means, including crimping roller means and mechanical means for positively controlling the movement of said crimping roller means toward and away from the edge of the cap in dependence on the raising and lowering movements of the container and cap on the platform means.
A capping machine for crimping the caps of containers comprising housing means, container-receiving platform means, drive means including first means for rotating said platform means and second means for controllably raising and lowering said platform means, and a crimping mechanism above the platform means and operable to engage the cap of a container on the platform means when being raised and rotated by said drive means,
- wherein the drive means includes drive shaft means, a platform shaft means operable to be raised and lowered and operatively connected with said platform means, further shaft means, cam means operatively connected with said further shaft means for rotation with said further shaft means and provided with cam surface means, a cam follower operatively connected with said platform shaft means and operable to engage said cam surface means, and means drivingly connecting said drive shaft means with said platform shaft means and with said further shaft means.
A capping machine for crimping the caps of containers comprising housing means, container-receiving platform means, drive means including first means for rotating said platform means and second means for controllably raising and lowering said platform means, and a crimping mechanism above the platform means and operable to engage the cap of a container on the platform means when being raised and rotated by said drive means,
- wherein the crimping mechanism includes a downwardly tapering camming surface means, an abutment member mounted on the shaft within said housing member and axially displaced with respect thereto, a crimping head base means fixedly connected with said shaft, a crimping roller means engageable with said caps, and linkage means operatively connecting said crimping roller means with said crimping head base means and including a cam follower member operable to engage the tapering camming surface means of said housing member during axial movement of the abutment member,
- wherein said linkage means includes two linkage members on each side of said crimping head base means, said linkage members being pivotally connected with said crimping head base means and with said crimping roller means.
