The Hoyer Dino C multiple row pick-up system
may be used with a wide range of products
(products on stick handles, ball cones, wafer cups
and products without sticks).
The Hoyer Dino C pick-up machine is composed
of the following main components:
Product pick-up unit with a series of
interchangeable grippers (Pos. 1, Fig. 3.1).
Product transport with interchangeable rollers
(Pos. 2, Fig. 3.1).
3.1 Description of the machine
Chocolate coating tank for products on sticks and
ball cones (Pos. 3, Fig. 3.1).
Set of tanks for coating products on sticks with fruit
juice.
Set of interchangeable grippers (Pos. 4, Fig. 3.1)
for releasing products on sticks and ball cones onto
a belt synchronised by a Hoyer Charta single row
wrapping unit.
Smooth belt for conveying products without sticks
(Pos. 5, Fig. 3.1).
Electrical cabinet (Pos. 6, Fig. 3.1).
Pneumatic cabinet (Pos. 7, Fig. 3.1).
Operator interface panel (Pos. 8, Fig. 3.1).
Fig. 3.1
The pick-up unit, which is constructed with a
rotating arm (Pos. 9, Fig. 3.1) holding the grippers,
picks up hardened products from the worktable at
the tunnel exit.
The grippers are opened and closed to pick up
products by pneumatic cylinders integrated and
controlled in parallel by a single pneumatic valve
located inside the pneumatic cabinet. Movement
is synchronised by an encoder under the worktable
and the PLC programmer located inside the
electrical cabinet, which interfaces with the main
tunnel programme.
3.2 Operation
Before the grippers close, the arm follows the
movement of the products onto the trays (Pos. 10,
Fig. 3.1).
Once the products have been gripped, a hammer
positioned underneath the trays detaches the
products from the trays.
The set of products that has been picked up is
positioned on the rollers as the arm rotates (Pos. 9,
Fig. 3.1).
The rotation of the arm and its movement following
the products to be picked up are controlled by two
servomotors ((Pos. 11, Fig. 3.1) to ensure
