We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 47>. Bobin certainly rolls. When placed horizontally on a sloped surface, it indeed rolls down to the lower side. However, in reality, if it rolls down a mountain path, it would come into contact with uneven ground, stones, etc., and the wire itself would likely become very damaged due to dents, scratches, and wear.

The product that has been judged as "non-conforming" by the Quality Assurance Department and has "deviated from the regular route" cannot be shipped from the factory as a "first-class product" for valid reasons. The reason Bobin-kun is classified as a "non-conforming product" is that "there is no product label attached."

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 52>. Recycling as scrap. Reborn as metal raw material. This can be considered the most standard destination. The collected scrap varies and is not limited to just bars and wire scrap. Offcuts and defective products from various processing factories, including sheet materials, strip (thin plate) materials, flat steel, pipes, and metal shavings, are gathered and re-melted. The rule is to identify and collect the steel types as accurately as possible by each type.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 57>. The tapered bobbin is a bobbin used for floor placement. The tapered bobbin allows you to pull the wire upwards without rotating the bobbin itself, keeping it on the floor. In the case of floor placement, since the wire is pulled upwards, it is easily affected by wire memory. If the diameter of the wire memory is small, it can easily create points on the wire that resemble knots (kinks). Therefore, when pulling the wire, we apply resistance using whiskers to prevent this from happening.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakae, <Episode 62>. While automation can be implemented for tasks like the automatic attachment and detachment of bobbins, as well as rewinding and splitting, I believe it is very difficult to achieve full automation and unmanned operation for all processes. To automate and operate without human intervention, robots would need to perform these tasks. However, depending on the nature of the work, some processes may require a very high capital investment if done by humans.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakae, <Episode 71>. At Sakae Nobu, we are engaged in "manufacturing" with the factory operating at night, but the amount of work and the number of employees involved are significantly lower compared to the daytime. Therefore, if you walk around the factory, you will find only a few people working. Only a part of the manufacturing department's drawing section and the annealing (heat treatment) section are operational, while the shipping inspection section, die section, delivery section, quality assurance room, sales department, purchasing department, accounting department, etc., are all on break.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobuaki Sakai, <Episode 72>. "We are the 2S Patrol Team" At Sakai Nobuaki, we regularly inspect the 2S conditions within the factory across departments and sections, providing feedback and improvement recommendations. Excuses may arise from each area, but 2S activities are necessary for the comfortable operation of the company. While we aim to establish daily 2S practices, the work is done within a limited timeframe, and there are moments when things appear chaotic.

Since only those items are there, there is no chance of mistakenly taking something out, and there is no need to search around for necessary items. The "products" have labels attached, making it clear what they are. If this is not done, you will be strictly reprimanded by the "2S Patrol Team," just like Bobin-kun, who is wandering around the factory.
