Abstract
A centering unit for aligning at least two grouped vessels, a liftable and lowerable precentering mechanism as well as a liftable and lowerable final centering mechanism being provided so as to improve the alignment. According to a preferred embodiment, the precentering mechanism may include a plurality of subcentering mechanism so that vessels coming from different infeeds can be centered by mechanism a centering unit.
Claims19
A machine for treating at least two grouped vessels comprising a treatment station, at least one rotary plate for receiving thereon a plurality of vessels and at least one centering unit associated with a respective rotary plate for aligning at least two grouped vessels relative to one another, comprising a liftable and lowerable precentering means and a liftable and lowerable final centering means, the precentering means and the final centering means being implemented such that they can be lifted and lowered independently of one another and wherein the precentering means is implemented such that it can be lifted and lowered via a pneumatic control and wherein the total stroke of the precentering means comprises at least partially the stroke of the final centering means.
A method of aligning at least two grouped vessels, in a machine for treating vessels having a treatment station, at least one rotary plate for receiving thereon a plurality of vessels and at least one centering unit associated with a respective rotary plate for aligning at least two grouped vessels relative to one another, comprising a liftable and lowerable precentering means and a liftable and lowerable final centering means, the method comprising:
- a) precentering the grouped vessels with a liftable and lowerable precentering means, and
- b) final centering of the precentered vessels with a liftable and lowerable final centering means, wherein the precentering means and the final centering means are implemented such that they can be lifted and lowered independently of one another, the precentering means being lifted and lowered via a pneumatic control and wherein the total stroke of the precentering means comprises at least partially the stroke of the final centering means.
A machine for treating at least two grouped vessels comprising a treatment station, at least one rotary plate for receiving thereon a plurality of vessels and at least one centering unit associated with a respective rotary plate for aligning at least two grouped vessels relative to one another, comprising a liftable and lowerable precentering means and a liftable and lowerable final centering means, the precentering means and the final centering means being implemented such that they can be lifted and lowered independently of one another, and wherein the precentering means is implemented such that it can be lifted and lowered via a pneumatic control and wherein the final centering means is moved up and down along a control track.
