[Case Study] Chain Breakage of Conveying Conveyor

Frequent cutting troubles with the chains used in the conveyor for transportation. Here is an example of the introduction of a magnetic proximity switch!

At a wood processing manufacturer, there were frequent troubles with the conveyor for transporting "particle boards (3×6 feet × 80 sheets/1 lot)." There were requests such as, "The conveyor's top chain reaches its material lifespan at 1,650 rotations, so we want to replace it before then," and "We want a sensor that can reliably count so that we can ensure it is worn out by 1,650 rotations." Therefore, we installed the magnetic proximity switch "DW-350" made by Makome Research Institute under the conveyor and attached the magnetic body "SMG-100N" to the top chain. As a result of the improvement, by installing the "DW-350," we were able to manage the count of the top chain, transitioning from reactive maintenance to preventive maintenance. *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Case Summary (Partial)】 ■Trouble Case (Request) - The top chain's conveyor rotation speed reaches 1,650 RPM, which is the material's lifespan, so we want to replace it before that. - We want to shift from "reactive maintenance" to "preventive maintenance." - Since it is wood processing work, photoelectric sensors cannot be used due to dust impact. - We want a sensor that can reliably count to ensure wear is confirmed up to 1,650 RPM. ■Trouble Situation and Loss - Trouble frequency: 1 time/57,600 seconds (2 days of operation) - Trouble recovery time: 1,200 seconds/1 time - Loss: 18,500 yen/day, 37,000 yen/2 days ■Improvement Points and Expected Customer Effects - The DW-350 is a non-contact type that detects up to 40mm. - A magnetic body is installed upside down on the top chain, allowing for 2-channel output to reliably count the rotation speed. - The DW-350's magnetic detection element is equipped with a "saturable coil." ■Improvement Effects and Benefits - Trouble frequency: 0 times/28,800 seconds - Trouble recovery time: 0 seconds/1 time - Line downtime: 0 seconds - Loss: 0 yen/day *For more details, please refer to the PDF document or feel free to contact us.
