Bag-emptying machine – with pneumatic transport and screw compactor

Our fully automatic bag-emptying machine can empty granulate filled bags of 25Kg. Pallets are placed at the side of the infeed conveyor with a forklift truck. After placing the pallet on the infeed conveyor, the conveyor will transport the pallet to the lift, the lift will transport the pallet upwards to a shuttle with integrated grippers. The integrated grippers will grab a layer of 5 bags of the pallet and ride this to the emptying process. Here the shuttle will drive the bags over rotating blades and a unique shaker system. This unique shaker system will ensure that the bags will be emptied for 99.98%. the product will be collected in the product hopper.

Normally we equip the main control cabinet with an HMI. In this case the main control cabinet is mounted in a space were there is no overview over the machine.

Because operators like to have a complete overview of the machine, we have equipped this machine with a control cabinet at the front.

With the HMI that is mounted inside this control cabinet you have complete control and overview of the emptying process.

The capacity of these machines is between 10 and 30 tons per hour. This depends on the configuration of the machine and the product.

Pallet stacker

After emptying the whole pallet, the empty pallet will be fed out to the pallet stacker. Here the pallet will be stacked to a maximum of 15 pallets or a certain value. When this setpoint is reached the stacker will put the pallet stack on the conveyor where it can be picked up with a forklift.

Pneumatic transport to silo’s

After the product has fallen into the product hopper the product will be evenly dosed into the pneumatic transport piping using a rotary valve.

In the blower piping we integrated a 3-way valve to transport the granulate to two different silo groups.

Screw compacter

After emptying the shuttle will release the empty bags into a bag hopper.

This bag hopper is connected to a screw compactor. This will cause the empty bags to fall onto a short screw that is located inside a tube. The screw forces the bags through the tube into an endless bag that is clamped around the end of this tube with a special band. The pressure of the screw eventually compresses the bags about two thirds. When the compactor is full a limit switch is reached.

Capacity: 100 – 200 Bags
Power: 3 kW

Every machine configuration is possible

Our machines can be configured or adapted completely according to the wishes or specifications of the customer, please contact us for the possibilities.
