Corrugated Cardboard Double Facer Stacker

Corrugated Cardboard Double Facer (Stacker)

Corrugated Board Prodution Line Dry End Series

NC servo double layer up & down stacker

General Introduction to Equipment

This corrugated cardboard double facer (stacker)machine is used for board arrangement, overlapping conveying, stacking and transverse discharge completed at late segment of production lines. It could be able to match with high and mid-speed corrugated paper production lines, realize automatic counting with computer and automatically separate stacks based on preset number of each stack and precisely change the order automatically.

Improved Code: I, generation I; Ⅱ, generation II and etc.

Functional Feature

The upper layer uses four-segment flat belt for board conveying and lower layer uses three segment flat belt for board conveying which are both controlled synchronously with production line speed and both could have its speeds automatically adjusted during stack change or order change to ensure smooth and reliable operation

Upper layer and lower layer are operated separately, so that two specifications of boards can be stacked at the same time.

The board feeding end of upper and lower layers uses four groups of carbon fiber paper pressing brush for paper pressing and adjusts the pressing based on length of boards. A pneumatic board supporting board and a pneumatic board pressing steel belt are arranged between the two rear conveying segments of the upper and lower layers, so as to automatically control the lifting, automatically and reliably separate boards while stacks and orders are changed.

The suspension basket stacking of upper layer and gantry type stacking of lower layer both are controlled by servo motor to ensure stable lifting.

The flat belt type stacking and transverse discharge functions used by upper and lower layers could ensure the boards are stably output when a preset number of stacking is reached.

The position of rear baffle could be automatically adjusted by AC servo motor to realize fast order change and effective output of boards.

The laser distance-measuring device could accurately measure stacking height.

With motorized trolley, the boards that transversely discharged are output quickly. In case of no motorized trolley, conveying and packing platform will be provided.

The paper conveying strap uses special tensioning device which could be adjusted easily and serve for long service life.

Operation monitoring of gantry type stacker's touch screen is achieved easily and visually.
