Are you still carrying or already automating? - Palletizing robots at HAKRO

Palletizing system from ro-ber at our customer HAKRO

Our customer HAKRO, a leading supplier of corporate fashion for work, leisure and sport, increasingly relies on automated and digitized processes in its sustainability strategy. Digital and automated? Of course SuPCIS-L8 and SuPCIS-MFC (Material Flow Controller) should not be missing! Together with a new complete palletizing system, we help HAKRO to achieve its goals in logistics: to support the employees in their daily work in logistics and to relieve them physically. How does this look like in practice?

The palletizing system consists of a container and pallet conveyor system including control technology from GEBHARDT and palletizing robots from ro-ber.

After the delivered boxes have been unloaded from the truck and placed on the container conveyor, they pass several detection points with scanners and sensors. These record various information about the boxes. Each scanner reads the label on the box (the so-called loading aids label), which uniquely identifies the box and its contents. With the help of the sensors, a contour check is carried out, whereby the length, width and height and from these the volume of the respective box is determined. In addition, a scale is integrated into the tote conveyor system to determine the weight of a box.

The control system of the tote conveyor system transmits the recorded data to the AMS, which uses this data to decide whether the respective box can be automatically palletized by the palletizing robot and must be moved into the palletizing system or whether the box is manually palletized and thus discharged to the manual palletizing station. The transport order is issued by the MFC to the control system of the container conveyor system. If, for example, the contours of the box are out of tolerance or the loading aids label could not be detected, the box must not run over the palletizing system.

In the palletizing system, the boxes are moved to transfer stitches, from where they are picked up by the robot and transported to the respective target pallet. The boxes are usually formed in pairs, since the palletizing robot can transport two boxes at the same time. Single runs are only performed if no other box with the same sorting criteria is detected on the tote conveyor line in the specified time period or if it is a no-read box. In such a case, the loading aids label could not be read by the scanner at the beginning, so that the information about the box and the article it contains is missing.

As soon as the box or pair of boxes has arrived at the transfer point of the tote conveyor system, SuPCIS-L8 instructs the palletizing robot to transport the boxes to the target pallet determined by the avalanche beacon. If the pallet is full, the avalanche transceiver or the MFC requests the pallet conveyor system to automatically remove the pallet. After the full pallet has been removed, a new pallet is automatically fed from the pallet stack.

 

With the introduction of the palletizing robots, the employees save a lot of muscle power and, above all, kilometers per day.
