Simple Structure

The simple and rigid structural design concept of the RX240NEW has been applied to this compact yarn spinning system.

Suction Ducts (48 spindles per section)Placing the suction ducts on the upper part of the roller stands results in a simplified design and shortened piping route.

Condensing UnitsFor easier handling, each 4-spindle condensing unit can be con-veniently detached and disassembled without using special tools.

Delivery RollersThe rollers are driven by a geared front-bottom roller and mainte-nance-free carrier gear, resulting in a simpler structure.

From the Designer

When developing this compact yarn spinning system, we had to keep in mind not only how to improve yarn quality but also how to increase operability and make maintenance easier. We gave the condensing unit an easy-to-handle, 4-spindle integrated structure so that it could be readily detached from the main unit and easily disassembled and reassembled during maintenance. We also designed it so that it could be fitted onto the currently available RX240NEW, turning it into a compact yarn spinning frame simply by adding and exchanging some parts. We’ll con-tinue our commitment to developing better products by listening closely to customer requests.

A Message From the Service Department Mitsuhiro Iwasaki, Service Department Manager

First of all, thank you very much for your continued patronage of Toyota textile machinery. It is much appreciated.Maintenance is an important aspect of ensuring consistent quality and long-term reliability. Here, we would like to bring to your attention a few important maintenance items identified by our service technicians in the course of after-sales service. While these items are extremely basic, if neglected, they could become the source of serious problems.

Air Jet Looms1. Proper preparation of the installation location and correct

equipment set-up are the two most important factors in ensuring the safe long-term use of looms with consistently high performance. Follow the instruction manual carefully, especially in regard to foundation work for the floor, electrical grounding connections, and the air supply system.

2. To ensure the reliability of components and maintain excellent fabric quality, be sure to lubricate the beating section and the let-off on a regular basis.

3. To achieve stable weft insertion, we encourage you to periodically clean the reed. Allowing oil solutions or sizing materials to build up in the reed dents will severely degrade the consistency of weft insertions.

Water Jet Looms1. Shedding connecting rods in the crank

shedding mechanism should be lubricated each time the loom’s beams become empty (every 10 days). This section is subject to a great deal of water influx, and regular lubrication is important to maintain adequate levels of grease on friction surfaces.

2. It is important to check carefully for overstretched motor drive belts. Press on the belt to check whether the belt bows adequately. Overstretching will not only reduce the service life of the belts, but also shorten the service life of motor bearings.

Spinning Machinery1. It is important that foundations be designed and built

to provide adequate floor loading capacity. This is critically important in maintaining a flat floor surface over the long term. Also, because even a tiny eccentricity in rollers will have an impact on yarn quality, it is important to check the levelness of the machinery itself.

2. To maintain consistent yarn quality, the recommended change interval for spindle oil is 4,000 hours.

3. To bring the spinning machinery to a smooth stop, it is important to adjust the main brake gap. Be sure to make checking the gap a regular maintenance item.

A Look at Toyota's Global Service Centers

Part 7: ChinaShanghai Service Center

Wujiang OfficeSheng Xi He Qiao Dong, Nan Huan Road, ShengZhen Town, Wujiang City, Jiangshu Sheng, ChinaTel: +86-512-63569608Fax: +86-512-63563517

Toyota has established 11 service centers aroundthe world to supply spare parts and provide after-sales service, and is developing a system torespond more quickly to customer needs. In thissection of each issue, we will introduce one ofthese service centers. This issue, we take a look atthe Shanghai Service Center’s Wujiang Office.

The Wujiang Office of the Shanghai Service Center was established in June 2002 in the cityof Wujiang in Jiangsu Province. This makes it the third service base in China afterShanghai and Shaoxing. The Shanghai Service Center, with its easily accessible andconvenient location, is in charge of such matters as installation supervision, after-salesservice and parts sales across the country. The Wujiang Office, on the other hand, isaiming to be a service center close to the local area. It’s located in an area where many ofour customers have their mills so they can easily visit our office.

Presently, Wujiang is aiming to be one of China’s biggest textile industry centers,producing high value-added fabrics. Many companies are reinforcing their plants andequipment and pushing forward with technical innovation, and Toyota’s air jet looms are atwork at many of these mills. We expect to sell more air jet looms, water jet looms andpreparatory machines, making the role of the Wujiang Office more important.

The Wujiang Office currently has 5 full-time employees with help from some ofthe staff of the Shanghai Service Center. Together they promptly handle customer enquiriesand offer full service including giving advice on installing textile machinery and after-salesservice for Wujiang and the surrounding areas.

Wujiang Office, Shanghai Service Center

Everyday is a Challenge!Installation and After-SalesService EngineerWang Shu Sheng

I joined the Shanghai ServiceCenter four years ago and havesince installed mainly air jet loomsacross the country and providedafter-sales service. I came to theWujiang Office upon its establish-ment. I still have a lot to learn compared to my Japanesecolleagues, but four years of experience has given meconfidence in my skills. Once a month, the Japaneseengineers in Shanghai hold a technical training meeting, and Itake the opportunity to raise my skills by asking questionswhenever I attend these meetings and whenever I accompanyJapanese engineers on visits to customers’ mills. I am wellaware that improving our skills leads to higher customersatisfaction and will continue my efforts.

Service ManagerSun Xiao

After graduating from textile college,I worked as a designer at a textilemachinery manufacturer. I joinedToyota’s Shanghai Service Center in1999. Currently, as manager of theShanghai Service Center, I am alsoresponsible for the Shaoxing and Wujiang Offices.

It’s been challenging to keep up with the advances intechnology. This year in particular, a few thousand air jet loomswere installed in the Wujiang area, making our jobs morechallenging.

The service center’s main responsibilities are loominstallation and adjustment, after-sales service, spare partssupply and repair. In the future, we hope to expand ourbusiness range to include technical training for our customers.

Thai Rung Textile Co., Ltd.

Thai Rung Textile Co., Ltd. (TRT), the core of the TTIGroup, is located near Bangkok. Based on the slogan“Achieve world standard and maintain it,” the companyhas purchased Toyota machines every year for the pastseveral years. TRT currently has 38,000 spindles ofToyota ring spinning frames, led by the 21,600 spindles

TRT’s Motto

Achieve World Standard and Maintain ItGive us your thoughts on Toyota machinery.We first started using Toyota RY4 ring spinning frames in1985. The next year, we beganusing FL16 roving frames, and in1995 we purchased some RX220ring spinning frames. All of thesemachines are still in fine condi-tion and operating today.Although we had some othercompanies’ machines, wedecided to replace them withToyota machines. In 2001, wesimultaneously installed 21,600spindles of RX240NEW ringspinning frames along with FL100roving frames, DX7A drawingframes, and VC5 combers so we could spin polyester andcotton blended yarns. With an average machine speed of20,000 rpm, high yarn quality and productivity, ease ofmaintenance, and durability of parts, we are very satisfied. Inshort, choosing Toyota machines was the right decision.

How has Toyota’s after-sales service been?So far, we are satisfied with Toyota machines and after-salesservice. In fact, we are very pleased with the way Toyota haspromptly dealt with all matters, no matter how small, duringeverything from machine installation to start of operation.

of RX240NEWs that it installed in 2001. These machinesspin T/C Ne45 yarn at an average machine speed of 20,000rpm, among the fastest speeds in the world.

We spoke with the company’s managing directorMr. Mongkol Mangkornkanok about how Toyota helps hisbusiness.

Do you have any requests for Toyota?Electricity costs are continuing to increase. Because the cost ofelectricity accounts for 35% of spinning yarn, we would like tosee Toyota put more effort into developing machines thatconsume less power. Also, because we must meet customerneeds for varying yarn counts, we would like to see Toyotadevelop a system for fast and easy ring changes on any kind ofring spinning frame.
