Environmentally friendly brushless products contribute to reducing CO2 emissions by improving energy efficiency.
The adoption of a high-efficiency brushless motor eliminates the need for brush replacement, resulting in a simple design and greatly improved durability. The motor generates little heat even during continuous operation for long periods of time, and always provides stable torque accuracy. Additionally, no carbon particles are emitted, the work environment is kept clean, and electronic components are not adversely affected. Additionally, low noise and vibration minimize noise and radio interference during work. Brushless screwdrivers help improve the quality of screw tightening and support environmentally friendly manufacturing.

It reduces waste and waste due to poor screw tightening and promotes circular economy.
Conventional screw tightening work often relies on the experience and intuition of the operator to determine whether the screw has been tightened correctly, and quality has been influenced by the skill of the individual. The skilled driver automatically counts the number of rotational pulses of the motor and detects screw tightening errors with high precision in real time. Additionally, by changing settings and outputting tightening data from a PC or PLC, you can streamline management, ensure traceability, and support safe and secure screw tightening work.

Fujifilm Manufacturing Ebina Office
Fujifilm Business Innovation is a leading company in multifunction devices and printers. Of Fujifilm Manufacturing’s four domestic factories responsible for this production function, the Ebina Plant assembles final products for printers for commercial printing. Achieve high-skill production by proactively implementing production innovation activities based on IPW. The know-how cultivated here has been standardized as a production platform. In particular, the large-scale products in the commercial printing field handled by the Ebina Office are production goods that are directly connected to customers’ businesses, unlike printers used in general offices, so they are manufactured to a high standard under strict quality control. We are promoting.

The number of screws tightened per day is over 100,000. For Fujifilm Manufacturing’s Ebina Plant, which produces high-speed,
high-performance printers for commercial printing, screw tightening is a fundamental manufacturing process that is incorporated into all processes. Because a single missing or loose screw can lead to product defects, a strict control system for fastening is essential. The Ebina Plant, which has been developing production innovation activities based on Fujifilm’s Innovative Production Way (IPW), has introduced Hios’ built-in screw counter pulse system with the aim of further improving quality and high efficiency. ‘s digital driver “Skilled Worker BLG-BC2”. It called for fundamental reforms at manufacturing sites.

The Ebina Plant’s production method is what is called “one piece flow.” This is a method in which machines of different types and destinations are mixed together on one line, and after workers complete assembly work in their own process, they are transferred one by one to the next process. It starts out as just a skeleton, but as it moves down the line, units and modules made on sub-lines are attached to it, and in the end it becomes a finished product. Workers assigned to each process and sub-line perform assembly work without waste, but Toshihiro Furuta, manufacturing manager, says, “Safety and quality come first.Standardize work and prevent stockouts and different items.” We are carrying out various activities such as efforts to improve safety, but our top priority is ensuring safety and reducing the burden on workers.This will not only improve quality, but also improve productivity.” The key is to create products that both eliminate defects and reduce the burden on workers.
In production innovation activities based on IPW at the Ebina Works, the screw tightening work area is also an important target for improvement. This is because “we spend a lot of time tightening screws,” said Furuta, manufacturing manager. Many of our staff members are female, and the work they do to tighten screws hundreds of times a day has caused some cases of tendonitis, so the adoption of electric screwdrivers was becoming inevitable. About three years ago, we decided on the “Skilled Driver”, which weighs only 425 grams, which is significantly lighter than other companies’ products. The grip was also attractive because it was slim and didn’t take up much space, and its diameter was ergonomically calculated to fit easily in a woman’s hand.

The biggest deciding factors were the screw counter function that counts the number of screws tightened, the pass/fail judgment function that detects screw tightening errors with high precision, and the new function that can output tightening data externally. Yoshihiko Yamada, who oversees the manufacturing technology group, says, “To tell you the truth, in the past, there were people who counted the number of screws needed for each process, and then distributed them to each process. The number of people was controlled,” he said. With the introduction of the “Skilled Driver”, it has become possible to input the number of fasteners required for each model into the driver, which has led to “not only a reduction in management man-hours, but also the establishment of a guarantee on the number of fasteners that does not rely on humans. It also has the advantage of improving quality by being able to detect defects such as slanting and diagonal tightening,” says Mr. Yamada.
Skilled workers are able to reduce the burden on workers and ensure stable screw tightening quality. For example, loss caused by poor screw tightening. It’s not just the screws themselves that are discarded. This may lead to damage to product components and even loss of the product itself. In other words, “skilled drivers” are also tools that can contribute to an environmentally friendly society. HIOS’s screw fastening system, which uses a brushless motor to save energy and emit no carbon, has been awarded the “Digital Driver” screw fastening system, which will be recognized in 2022 as an award for products and services that incorporate outstanding environmental considerations. Received the Encouragement Award from the EcoPro Awards.
On the other hand, the ability to change settings from outside is also great,” says Katsutoshi Sakai of the Manufacturing Technology Group, who is involved in selecting jigs and equipment for on-site
improvements. Another appeal of “Skilled Worker” is that it has a rich lineup of peripheral equipment to support it. By linking with the optional “BLG-IF2″, up to four patterns of screw tightening number, rotation pulse number, etc. can be stored, and functions useful for production innovation are provided, such as externally switching pattern settings. Particularly on the Ebina line, where there are a mix of models with different numbers of fasteners and rotational pulses depending on the destination, Mr. Sakai says, “It saves the trouble of switching between screwdrivers, which reduces the burden on workers and line supervisors.” It can be said that “skilled drivers” have brought about fundamental reforms in manufacturing sites.

Currently, a total of 230 “skilled drivers” are working at the Ebina Plant. The majority of screw tightening work is performed by “skilled workers.” The use of a brushless motor has resulted in a “longer lifespan and less frequent breakdowns,” and because it is lightweight and compact, there have been no cases of tendonitis when tightening screws. Furthermore, since the screwdriver itself takes the place of the operator and determines whether the screws have been tightened correctly, the operator can naturally master the correct fastening work “without even thinking about it,” which “makes it easier to train new employees.” Hios’ ability to respond to customers cannot be overlooked. For example, in order to avoid the risk of the
screwdriver’s power cord getting caught on the foot of a worker when tightening screws while moving, the company has shown a flexible response to customers, such as providing a custom-made lightweight curl cord, but IPW production The Ebina Office, which is involved in innovative activities, has high requirements. “Our products are production goods that support our customers’ businesses, so if a quality problem occurs, it will directly affect our customers’ production activities,” said Furuta.
Ebina Office aims to further improve quality. Hios strives to meet the diverse needs of individual companies. It is likely that the two companies will continue to work together to develop further production innovation initiatives.
