Automatic Pallet Inverter/Exchanger

pallet-exchanger-blueprint

This machine is a dual clamping 180 degree pallet inverter/exchanger and is designed for use in conjunction with a counterbalanced forklift for loading and unloading.
It is used where:
1) A load has to have the pallet swapped – for example when a wooden pallet is swapped for a plastic pallet, or when a Pool pallet needs to be swapped for an in-house pallet.
2) A load needs to be inverted
3) A load has a damaged item near the bottom, which must be removed or swapped.

HOW IT WORKS
The machine has a hydraulic power pack activating cylinders which open and close the platens and cause the mechanism to rotate. The automatic functions are controlled by a PLC and various sensors to determine the sequence of activities. All functions can be manually performed from the touch screen on the control box when the unit is in manual mode.

SEQUENCE

1) SWAPPING PALLETS IF PRODUCT ORIENTATION UNIMPORTANT
The loaded pallet has the replacement pallet placed upside down on top. It is then placed with a forklift on the machine’s platen as close to the rear and side panels as possible. The forklift should reverse out of the machine zone and the operator then activates the cycle. The PLC will then take over and start to clamp the load between its platens – when load sensors are activated the clamps will stop and the turntable will begin to rotate. When the load is inverted 180 degrees, the clamps will automatically open allowing the operator to remove the load. The product is now sitting upside down on the new pallet. The old pallet can be removed.
The machine turntable can be left in this position in readiness for the next task.

2) SWAPPING PALLETS IF PRODUCT ORIENTATION MUST BE MAINTAINED
The loaded pallet is placed with a forklift on the machine’s lower platen. The cycle is activated. When the load is inverted 180 degrees, the clamps will automatically open allowing the operator to remove the old pallet and replace it with a new pallet (positioning it upside down)
The cycle is again activated, which again rotates the load back to its original position. The load is now supported by the new pallet, and is sitting right way up.

CONTROLS

The external control panel is located on a pedestal and can be positioned in any convenient location near the machine. It has a HMI screen (touch screen) and an Emergency Stop button. All machine functions are operated from the Touch Screen.
