WIM – Window Cut for Order Picking

WIM cuts or punches a window in boxes with disorganized contents—at a rate of up to 500 boxes per hour. This is about five times faster than manual processing. The packages can then be moved to the warehouse with the picking window already in place and are ready for order picking.

“There are really only positive effects: The new process saves employees’ energy, prevents cuts, and, last but not least, protects the contents of the boxes.” – Head of Logistics Planning and Control, E-commerce Client

The automatic package opener—WIM (Window Method)—is used when cartons need to be opened at the front, such as during manual order picking.

WIM cuts or perforates to the desired depth using our patented PAM special blade.

Occupational Safety

Unlike manual opening, WIM requires no downtime, nor does its speed decrease over time—and there are no absences due to strikes, illness, or vacation. Damage to the goods during opening is completely ruled out.

Procedure

Cartons are fed into the WIM one at a time. The carton is clamped and measured (LxWxH). The carton then tilts backward to reduce the pressure of the contents against the inner wall of the carton. In addition, the front of the carton is pulled outward by a vacuum suction cup to further relieve pressure on the inner wall.

Next, a predefined window is perforated or cut into the cardboard. The cutting depth can be preset via the control panel display.

After perforation, the window can be completely detached and removed at a later time without the need for tools. During cutting, the window is removed from the cardboard by the vacuum suction cup immediately after the cut.

In the next step, the cardboard box is returned to a horizontal position and moves out of the WIM system.

Package sizes

The standard WIM handles packages ranging in size from 200 x 200 x 200 mm to 600 x 600 x 400 mm – without prior sorting.

Integration

Thanks to its standardized roller conveyor, WIM can be easily integrated into existing conveyor lines equipped with depalletizers, defect detection systems, robots, etc. WIM is ideal for use in order picking and goods receiving.
