The rubber material can also be changed to suit oil resistance, cold resistance, heat resistance, etc., ensuring durability. [Case Overview] ■ Issues before implementation: Supply became unstable due to wear of the guide and bowl. ■ Effects of implementation: Most aging deterioration can be addressed with just the replacement of rubber. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where the introduction of the vibration parts feeder "FR Series" has reduced chocolate stops during AI and image recognition. Although a combination of robots and image recognition vision systems was implemented, challenges arose such as difficulty in recognition due to the overlapping of workpieces and the inability to grasp workpieces close to the walls of boxes, leading to frequent chocolate stops. With the introduction of this product, it became possible to supply workpieces in bulk using either a person or a hopper on the parts feeder, effectively spreading out the overlaps. Since there are no obstacles during picking, this resulted in the ability to operate stably for long periods. [Case Overview] ■ Challenges before introduction: Unstable image recognition due to overlapping workpieces ■ Effects of introduction: Increased stability by spreading out workpieces to avoid overlaps *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where the introduction of the vibrating parts feeder "FR Series" has made it possible to accommodate multiple varieties.
