This device is a fully automated welding distortion correction system developed for construction machinery parts manufacturers. It automates the entire process from bulk picking for parts supply, robot welding, cooling transport, distortion correction, to palletizing. Compared to traditional manual distortion correction, it reduces the work time per process, achieving both uniform quality of heavy machinery parts and labor savings simultaneously. It can be optimized for each company's line configuration with full-order and semi-order support. We can flexibly accommodate requests for automation of only certain processes or phased implementation. *For more details, please feel free to contact us.

This is a modular unit that allows outsourcing of only the protective film application process for line builders and SIers. It adopts a double-sided simultaneous application structure compatible with 2m x 3m sheets, avoiding the risks associated with developing from scratch in-house. Since it can be easily integrated into the latter part of existing transport lines, it also reduces the risk of delays in the overall equipment delivery schedule. This enables us to address projects that were previously lost due to insufficient equipment capacity, while shortening in-house development time and increasing deployment speed. *For more details, please feel free to contact us.

This device is a semi-custom dual-sided simultaneous protective film application system that accommodates various types of sheet materials. It was developed in response to requests from a punching metal manufacturer and has been implemented in multiple construction material manufacturers (steel and resin-based). It can be retrofitted into existing conveyor lines as part of the laser processing → inspection → film application process. By applying film to both sides simultaneously, it achieves processing times that are less than half of the traditional single-sided application done twice. Changing the width and length of materials can be completed without tools, and it flexibly accommodates design integration with previous processes (inspection) and subsequent processes (palletizing). By eliminating the risks of uneven manual application and scratches, it significantly reduces the burden on operators, contributing to improved line operating rates and stable quality maintenance. *For more details, please feel free to contact us.

We will introduce the differences between the "R2 feeder with front-back and orientation alignment function" and the previous FR feeders, as well as a comparison with current solutions. This product can align front-back and orientation using the feeder alone. It is proposed as an alternative to needs that were thought to be difficult to address with only 3D robot vision for bulk picking. In the case of the solution currently under development, automation is possible with just our feeder plus a single-action actuator and the necessary number of axes. 【Differences from previous FR feeders】 ■ Previously: To align the orientation and front-back, it was necessary to use separate laser scanners or cameras for detection and additional mechanisms for alignment. ■ This time: It is possible to align front-back and orientation using the feeder alone. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of the vibration parts feeder 'FR Series' that we handle. When the bowl parts feeder operates for a long time, it gradually becomes difficult to maintain a stable supply due to wear, and even after consulting with the manufacturer, the repair costs became high. Our product can be addressed with just a replacement of the rubber in case of hardening, making it a low-cost solution. 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 vibration parts feeder "FR Series" improved the working environment with lower noise compared to conventional parts feeders. Various efforts to reduce noise, such as urethane coating for bowl parts feeders and the introduction of non-vibrating parts feeders, did not yield sufficient results. With the introduction of our product, objects are transported using a special rubber with numerous protrusions, which absorbs shocks. This significantly reduces noise because there is no collision or friction between the bowl part of the parts feeder and the transported items. [Case Overview] ■ Challenges before introduction: Tried various options like non-vibrating parts feeders, but noise was still a concern. ■ Effects of introduction: Achieved zero noise between the structure and transported items with specially shaped transport 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 made it possible to reduce defects in powder metallurgy and aluminum parts. Before the introduction, cracks and chips occurred in the powder metallurgy parts before sintering due to impacts from drops during poka-yoke, which lowered the yield. After the introduction, by transporting objects with a special rubber that has a large number of protrusions, the impacts were absorbed. This made it possible to minimize cracks and chips and supply the parts effectively. [Case Overview] ■ Challenges before introduction: A bowl parts feeder caused a large number of cracks and chips. ■ Effects of introduction: A significant reduction in defect rates with a specially shaped transport rubber. *For more details, please download the PDF or feel free to contact us.
