Abstract
An apparatus for closing a container includes closer stations. Each closer station has a closer tool, a coupling element, and a driver. The coupling element, with height-control, is positively guided to rotate about a machine axis thereof. Additionally, the coupling element, by way of the driver, drives the closer tool in a required vertical motion.
Claims20
An apparatus for closing a container, said apparatus comprising a plurality of closer stations that are arranged around a periphery of a rotor that rotates about a machine axis, each of said closer stations comprising a rotary drive for generating a torque, a closer tool comprising a shaft, wherein said shaft comprises a vertically-fixed upper-shaft portion and a vertically-movable lower-shaft portion, wherein said vertically-fixed upper-shaft portion contacts said rotary drive, thus forming a connection, wherein, as a result of said connection, which is a connection between said rotary drive and said vertically-fixed upper-shaft portion, said rotary drive causes said closer tool to rotate with said rotary drive, wherein, as a result of said connection between said rotary drive and said vertically-fixed upper-shaft portion, said rotary drive causes said vertically-movable lower-shaft portion to rotate with said rotary drive, a driver for causing said closer tool to engage in guided vertical motion via said vertically-fixed upper-shaft portion, said driver comprising a connection arm and a guide sleeve coupled to said connection arm, said guide sleeve comprising a bearing at a foot end of said guide sleeve, wherein said driver further comprises a plurality of linear bars extending along said guide sleeve, each of said linear bars comprising a head end connected to a foot portion of said upper-shaft portion and being configured to be displaced in an axial direction relative to said upper-shaft portion towards or away from said rotary drive, said linear bars being configured to be driven to rotate and to thereby transmit said torque to said closer tool, and a coupling element that provides positively guided height-control for raising and lowering said driver, said coupling element being configured to drive said closer tool in said guided vertical motion by way of said driver, thereby causing a change in a spacing between said closer tool and said container, said change in a spacing occurring concurrently with transmission of said torque to said closer tool.
