ABSTRACT:
An apparatus and method for automatically placing large plastic lids onto containers. Lids 24 are dispensed individually from magazine 11 onto slide 33. Each dispensed lid is individually retained at the bottom of the slide 33 for pickup by a container 41. The lid is urged onto the container by a pivoted roller 47 and further leveled by a roller 58 which is extended twice by a pneumatic piston to first contact a leading edge of the lid and to secondly contact a trailing edge of the lid. Thereafter a pneumatically operated lid securement means 61 comprising a convex plate 70' burps the air from beneath the lid and fully seats the lid on the container. The apparatus has various sensing means for sensing the depletion of lids from magazine 11, for sensing that a lid has been dispensed onto slide 33 and for sensing a container at the capping station. The sensing means control the various operations of the machine in proper sequence.
