6.4.10 Lid closing station
This station consists of crimping tools (Part. 1,
Fig. 6.13) mounted on the structure and
controlled by pneumatic actuators (Part. 2, Fig.
6.13).
The downward movement induced by the
pneumatic actuators (Part. 2, Fig. 6.13) brings
the crimping tools (Part. 1, Fig. 6.13) into contact
with the cones and lids, allowing the lids to be
fixed in position. The process is activated by pressing the button
(Fig. 6.2) and adjusted by means of cams
through the operator interface, with the appro-
priate inputs in the electronic programmer.
The position of each crimping tool is adjusted
independently of the others by adjusting the nut
and lock nut anchoring it to the stem of the
cylinder.
6.4.9 Lid feed station
This station consists of lid magazines (Part. 1,
Fig. 6.12) mounted on a support fixed to the
structure and a mobile cross-member (Part. 2,
Fig. 6.12), controlled by a pneumatic actuator
(Part. 3, Fig. 6.12), which moves the lid pick-up
suction cups.
During its upward travel, the suction cup support
(Part. 4, Fig. 6.12) is rotated 180° by a rotary
actuator (Part. 5, Fig. 6.12) which brings the
suction cups into contact with the lids stacked in
the magazines (Part. 1, Fig. 6.12). When the suction cups make contact with the
lids, a vacuum is generated allowing the lids to
be picked up.
During the downward movement, the suction cup
support (Part. 4, Fig. 6.12) is rotated 180° to
position the lids over the cones. The vacuum
switches off and the lids are released.
The station is activated by pressing the button
(Fig. 6.2). The vacuum control and the
rotation of the cylinder are adjusted by means of
the associated cams.
