Vorrichtung zum Versiegeln von Behältern durch Anbringen einer Deckelfolie

摘要

The present invention relates to a machine for sealing containers by applying a covering film, which comprises a framework (1) for supporting a container sealing unit (2) which is located between a unit (3) for feeding the containers (41) to be sealed and a conveyor (4) for removing the sealed containers. There are also pusher arms (50) which are detachably associable with multiple containers to transfer them from the feeder unit (3) to the sealing unit (2) and from the sealing unit to the removal conveyor (4). The particularity of the invention resides in the fact that the feeder unit comprises an accumulation conveyor (70) which is located upstream of the sealing unit and downstream of at least one buffer conveyor (75,77) which is interposed between the accumulation conveyor (70) and an external feeder conveyor. There are also detectors (90-92) for measuring the distance and speed of the containers fed onto the buffer conveyor (75,77); these detectors (90-92) drive the motors (76,78) that actuate the buffer conveyor (75,77) in order to feed the containers (41) at a preset speed and in a preset position onto the accumulation conveyor (70).
