Stacking station for thermoformed products

The stacking area is a short conveyor belt and a larger storage belt behind it of approximately three meters in length (depending on the customer 's requirements). The operator can pick up the goods with a clearing button without affecting the current stack. For the start-up of the deep drawing machine, the transfer can be switched off so that the starting parts can fall onto a conveyor belt after ejection and can be discharged laterally. After the corresponding connection, the stacking unit accepts the articles.

Challenge
The format change at the stacking station must be kept to a minimum, the cost of format parts should not exceed a fixed budget. The stacking system must be mobile for the format change on the thermoforming machine.

Technical solution
The surface suction, removal and stacking suction devices were covered with pre-cut films according to the format. This means that there are a maximum of two foils per format, whereby many formats are almost identical to each other and therefore no format change has to take place at the stacking system. A quick-clamping device with centring facilitates the repeated docking of the stacking unit to the thermoforming machines after a format change.

• Extraction unit
• Stacker
• Transport system

• Reduced costs due to faster format changes due to the flexibility of the pick and stack grippers
