4.4.2 Stacking
For stacking empty pallets, the pallet stack (at least one empty pallet) must always remain
resting on the pallet conveyor underneath the machine. This means the stack of empty pallets
is not suspended for a long period in the lifting forks (A) of the machine, thus reducing the risk
of a stack tipping over or pallets falling. Start position is step 1 (see list below).
Note
When multiple stackers share one pallet conveyor, it is advised to lift and lower
all de-stackers at the same time. In that way the pallet stacks will be resting on
the pallet conveyor most of the time.
1.
In the starting position, the vertical carrier is at the bottom position and the lifting forks are
extended into the stack, awaiting the signal that a new pallet is to be added to the stack.
2. When a pallet needs to be added to the stack, the main lifting cylinder (C) lifts up the
vertical carrier (D) to the top position, lifting the stack.
3. The new pallet can now be positioned underneath the stack.
4. The vertical carrier lowers the stack of pallets to the middle position and onto the single
pallet on the pallet conveyor.
5. The fork cylinder (B) moves the horizontal carrier (E) and retracts the forks of the stack.
6. The vertical carrier lowers to the bottom position.
7. The forks extend into the stack.
Sensor B7 detects whether there’s a pallet present so the stack above can be
lowered. Make sure that the arriving pallet ends up in the centre of the machine and
as close as possible to the back restraint.
Sensor B8 detects if the machine stack is too high. If so, the stack of pallets first
needs to be removed from the machine.
Sensors B3 on the lifting cylinder ensures that the carrier is in its bottom position to
grab the pallet.
WARNING
Danger of stack or pallets falling. When sensors are not properly
aligned or not functioning properly, it will result in serious damage to
the machine and/or create an unsafe situation.
WARNING
Danger of stack or pallets falling. Do not exceed total weight
and height of stacked pallets on the machine, it will result in
serious damage to the machine and/or create an unsafe
situation. See specification sheet for maximum load and pallet
height.
