6.3.4 Granule station
6.3.5 Lid feed station
This station consists of lid magazines (Pos. 1, Fig.
6.15) mounted on a support fixed to the structure
and a cross-member mounted on the up/down slide
(Pos. 2, Fig. 6.15) which moves the lid pick-up
suction cups.
During its upward travel, the suction cup support
(Pos. 3, Fig. 6.15) is rotated 180º by a rotary
actuator (Pos. 4, Fig. 6.15) which brings the suction
cups into contact with the lids stacked in the
magazines (Pos. 1, Fig. 6.15). When the suction cups make contact with the lids, a
vacuum is generated, allowing the lids to be picked
up.
During downward movement, the suction cup
support (Pos. 3, Fig. 6.15) is rotated 180º to
position the lids over the cups. The vacuum switches
off and the lids are released.
The station is activated using the “lids” switch (Pos.
17, Fig. 6.11). The vacuum control and rotation of
the cylinder are adjusted by means of the associated
cams.

This device, which is mounted on the structure, is
used to spread nut granules, chocolate flakes or
similar on the product. The unit consists of a hopper
(Pos. 1, Fig. 6.14) connected to distribution
channels (Pos. 2, Fig. 6.14) along which the
product flows due to the effect of the vibration
induced by a vibrator.
The quantity of product to feed is controlled by
adjusting the start and duration of the dose on the
timer housed in the control panel.
The quantity of granules can also be balanced as
follows:
-
slacken screws (Pos. 3, Fig. 6.14) using the
wrench and move the adjustable baffles (Pos.
4, Fig. 6.14), lifting them to increase granule
feed or lowering it to reduce feed.
When finished, tighten the screws with the
wrench.
- rotate the pressure regulator (Pos. 5, Fig. 6.14)
clockwise to increase the working pressure of
the vibrator in proportion to the quantity of
granules fed, and anticlockwise to reduce it.
Adjust the position of the vibrator by varying its
inclination with respect to the granule transfer
channels.
The station is activated with the “granule” switch
(Pos. 16, Fig. 6.20).
