Ring Spinning Frame

Taking energy efficiency and flexibility to new heights. Toyota’s RX Series of high-performance ring spinning frames—counting over 22 million spindles* in operation around the world—now enters a new generation. The all-new RX300 was developed in response to many customer requests for saving energy and spinning original yarn. The adoption of new high-efficiency motors and new pneumatic equipment ensures excellent energy-saving performance. The new long-frame design—which supports up to 1,824 spindles—employs Toyota’s proprietary technology to ensure high reliability and high performance, as...

Superior Economy Achieved with New Technologies Increased Energy Efficiency Comparison of Motor Efficiency In addition to the high-efficiency induction motors used in conventional models, the RX300 can be fitted with an optional super-energy-saving motor and a special inverter. These two options employ new technologies that enable energy-saving operation with even greater efficiency. Improved configuration of the pneumatic system and adoption of an inverter for the pneumatic motor ensures the ideal suction capacity that matches the number of spindles OPTION 2) Inverter control of the...

Ring Spinning Frame Highly Reliable Long-Frame Design Proprietary Technology Enables the Commercialization of 1,824-Spindle Machines Bottom Roller Split Drive For the RX300G GE gearing Draft motor Feedback correction Front roller rotation pulse Front roller rotation pulse Main motor The draft motor that shares part of the bottom-roller drive is driven by the vector control system, so there is little slip during rotation. And the main control CPU conducts feedback correction with the rotation pulses from the main motor and draft motor, so that the twists are uniform on all sections of the...

Positive Lifting Mechanism Displays Its Worth in Many Ways Servo Motor-Driven Positive Lifting Toyota’s Proprietary Positive Lifting Mechanism Instead of belts, the RX300 incorporates a screw shaft positive lifting mechanism. This eliminates disparity in the ring rail motion during long periods of continuous operation. The RX300’s smooth lifting motion also eliminates many of the problems associated with conventional lifting systems. Disruptions, such as stoppages that often occur during ring rail inversion and annoyances like chattering during descent, become things of the past. The...

Ring Spinning Frame Provides Outstanding Control and Operability Control System Using the Latest Electronics Technology High-Performance CPU Control High-precision control is achieved through a 32-bit CPU combined with our latest inverter and servo amplifier. A high level of dependability is assured for both spindle speed and servo-lifting control. Large Color Function Panel A 12-inch color function panel equipped with a Web browser improves interface ability. Connection to an internal or external network is possible for exchange of information or data. Function Panel Setting functions...

World’s Only Fully Change-Gearless Ring Spinning Frame (RX300E) The RX300E e-draft model is the world’s only ring spinning frame to eliminate all change gears. The twist and total draft gears need no replacing, and neither do the back draft gears. All spinning conditions, including settings for the servo motor-controlled ring rail lifting system, can be set on the function panel. Spinning condition settings Mid motor Back motor Back motor Front motor Fancy Yarn Spinning Device Many types of fancy yarns can be handled such as slub, multi-count, and multi-twist ones. High-response servo...

Ring Spinning Frame Toyota Original EST III Compact Yarn Spinning System with Perforated Apron Suction Key Features ■ Bottom delivery rollers allow positive drive of the perforated apron Cross-section of drafting part • Slip-free rotation increases service life of the perforated apron • Easy to maintain regardless of top roller diameter ■ Long perforated apron fitted with a tension device • Prevents accmulation of fly, and thus allows longer intervals between periodic maintenance ■ Condensing unit is easy to detach and disassemble • Periodic cleaning is possible in a short time • Easy to...

Toyota’s New Innovation—MOSAIC® Yarn Bottom roller speed The new MOSAIC® e-draft spinning device, which is capable of spinning injection slub yarn mixed with colored roving sliver, has the ability to produce yarns with a variety of fabric densities, yarn shapes, and slub size. This process is accomplished by combining different types of raw cotton and roving materials. Unlike conventional spinning technology that twists and drafts, this new technology “detaches and attaches” roving sliver. This concept is a totally new innovation that has never been introduced in the spinning industry. ●...
