ABSTRACT:
A capping machine in which open containers are successively brought to a capping station where a respective container is held against rotation to permit closing of the open container by rotating movement of a cap fed from a reservoir to a pick-up station; a head frame assembly of the machine includes a spindle assembly carrying a chuck at the lower spindle end and drivingly connected by way of an adjustable clutch and by way of a positive drive connection with a driving motor; additionally, the spindle assembly includes a double-acting pneumatic cylinder to cause reciprocation of the spindle in its axial direction; the various components of the head frame assembly are balanced about a pivot shaft on which they are mounted for pivot movement in unison so that the actuating force for pivoting the head frame assembly can be kept relatively small; in operation, the head frame assembly is pivoted from a capping position where the chuck is in alignment with the open end of the container, into a pick-up position where a plunger transfers the end cap in the chute to the chuck while the chuck and spindle asembly are in a retracted position. The head frame assembly is thereupon pivoted back into the capping position and the cap is secured onto the open neck of the container as the chuck is displaced by the pneumatic cylinder into the extended position.
