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 …
