4Equipment description
This chapter describes the system description of the Pallet dispenser PD1.
Please read this carefully to get a clear picture of what the software function block supports.
4.1 Basic operation of Pallet dispenser PD1
The design purpose of the pallet dispenser is too stack or de-stack pallets coming from or going to
other equipment parts of the system.
The pallet dispenser has two different configurations
1. Stacking pallets in depot (pallets coming from other equipment)
2. De-stacking pallets from depot (pallets going to other equipment)
CAUTION
Do not exceed total weight and height of stacked pallets on the pallet
dispenser, it will result in serious damage to the equipment and/or create an
unsafe situation. See specification sheet for maximum load and pallet height.
4.2 Equipment parts Pallet dispenser PD1
A. Pallet forks
B. Cylinder for closing/opening pallet forks
C. Cylinder for up-/downwards movement
D. Frame palletdispenser

4.3 Sensors Pallet dispenser PD1
B1 Upper position
B2 Middle position single pallet
B3 Bottom position
B5 Forks in pallet stack
B7 Pallet present under pallet dispenser
B8 Pallet dispenser depot status
B10 Middle position double pallet
B13 Forks out pallet stack
Y4 Valve upwards movement
Y12 Valve downwards movement
Y6 Valve close forks (move forks in pallet stack)
Y14 Valve open forks (move forks out of pallet stack)
Note
Dependent on the configuration depot status sensor B8 needs to be in the
correct position.
