JAT type air jet loom
The JAT710 air-jet loom is a new type of air-jet loom developed by Toyota Automatic Loom Co., Ltd. on the basis of the JAT610. Compared with the JAT610, it has many new features, including many advanced electronic control technologies, and the air consumption is reduced by 20%. %, the high speed can reach 1250r/min, and the vibration is reduced by 30%.
Suitable weaving varieties include ultra-wide decorative fabrics, elastic fabrics, airbags, seersucker, woven selvage and other fabrics.
Main structure Through three-dimensional station design and computer analysis, the optimization of the frame structure including the beam connection and the lightweight and moderate balance of the beat-up mechanism have been achieved.
Opening mechanism The negative cam opening uses computer analysis to achieve an ideal cam curve. To accommodate wide and heavy fabrics, there are also actively cam openings.
Crank openings: Simple crank openings with no angle of repose and multi-link crank openings suitable for high-density staple fiber fabrics are available.
Electronic shedding Each heald frame is driven individually by an independent servo motor. Through the multi-function operating panel, not only the opening form, but also the rest angle and closing time of each heald frame can be freely set.
Electronic dobby opening By simple operation on the multi-function operating panel, the dobby pattern, warp direction and weft direction can be set separately (standard). It can also be edited and saved by computer.
Electronic jacquard opening can weave high value-added fabrics such as interior decoration products and towels.
Automatic weft control device The new AFC automatically controls the spray characteristics of the trumpet-shaped serial nozzle that matches the arrival time of the weft yarn, so the yarn unwinding tension of the weft feeder changes accordingly, achieving stable weft insertion.
New ATC automatically controls the action time of the electromagnetic needle, ABS, and solenoid valve corresponding to the arrival time of the weft yarn. By adding a new real-time action mode, the weft flight changes can be responded to in an instant.
APCICS and other functions can input the fabric structure and rotation speed into the multi-function operating panel, and the computer automatically sets the arrival time and pressure of the weft yarn, and automatically controls the air pressure corresponding to the weft yarn flight state during operation.
The main nozzle is equipped with an air clamp (AGS) suitable for stretchable weft yarns such as elastic yarns.
Conical auxiliary nozzle The nozzle hole of the auxiliary nozzle has a conical angle, which prevents the diffusion of air and achieves stable weft insertion under low air consumption conditions.
Trumpet-shaped tandem nozzle The inside of the tandem nozzle is arranged into a trumpet shape to achieve high-propulsion weft insertion under low pressure.
Drafting nozzle Gives the weft yarn a draft at the right end to reduce the air consumption of the auxiliary nozzle. In addition, it also has an effect on the weft yarn relaxation phenomenon that occurs when weaving filament fabrics.
New solenoid valve We have successfully developed a new high-performance solenoid valve that is small, highly sensitive, avoids unnecessary consumption of air, and corresponds to the short distance of the auxiliary nozzle.
The auxiliary air tank is directly connected to the auxiliary air valve, without air loss from piping.
Electronic weft feeder The new electromagnetic needle corresponding to high speed not only improves the reliability of high-speed operation, but also can place a circle of weft yarn, improving operability.
The rotation rate of each electronic weft feeder corresponding to the speed control can be set independently. Due to the small rotation change, weft yarn breakage is prevented. In addition, when used in combination with the forced yarn feeder (OP), even multi-color fabrics with complex patterns can be stably inserted.
Anti-parking stall system The main control CPU with improved functions controls various devices such as let-off and take-up to prevent parking stalls.
Active stabilizing device is suitable for high-density and thick fabrics, and can be used for a wide range of fabrics. In addition, the high-speed tracking performance is also particularly excellent.
The negative stabilizing device is designed for thin fabrics such as filament and glass fiber weft.
Dual warp beams Both the upper and lower warp beams are equipped with independent servo motors, which can weave fabrics with different warp types.
The double warp beams are equipped with independent servo motors on the left and right sides to ensure uniform quality of wide fabrics.
Electronically controlled take-up device The weft density setting can be completed by inputting only through the multi-function operation panel (no need to change the gear type).
Others, the change of weft density during operation can also be set (the weft density type can be changed during weaving).
Air Clamp (AGS) Since the stretchable weft yarn is clamped in the main nozzle, it prevents the elastic yarn from leaving the main nozzle and the surface of the core yarn from being damaged.
Forced yarn feeding and weft feeder prevents poor yarn placement of weft yarns with long hairiness such as wool yarns and laminated yarns, or multi-color fabrics with complex structures.
Special weft insertion device for different types of yarns According to the weft insertion method, the pressure of the main nozzle for each weft insertion can be set independently.�, In addition, the pressure of the original auxiliary nozzle can be switched between high and low pressure. Therefore, the air pressure can be set according to the corresponding yarn type, and weaving fabrics that originally belonged to the field of rapier looms (the difference in weft yarn characteristics can be as large as 12 times).
The left and right standing electronic twisted edge device (ESM) is free to set the closed mouth angle due to the driver of the left and right independent electric motors. Therefore, the processing and operating operation of the weaving of the weft yarn have also been improved. In addition, the oil bath of the drive gear further improves the reliability of high-speed running components.
Stand-alone inverter Just input the required speed on the multi-function operation panel to change the speed.
Weft yarn automatic processing device (TAPO) When the weft yarn is inserted incorrectly, the faulty yarn will be automatically removed first, and then the loom will restart (with length measuring roller). The speed variable motor can change the speed of taking out the wrong weft.
The terry raising device adopts a cloth movement method that synchronizes the temple support and cloth fell plate with the terry raising, eliminating the phenomenon of cloth scratches.
Electronic terry device You can simply input the length of terry from the multi-function operating panel. The servo motor can continuously change the long and short loops and the length of the loops. Pitches 3 to 7 can be freely replaced.
Torque rod return (used for weaving pattern substrates) adopts low inertia torque to improve the follow-up of the let-off and ensure high-speed operation.
Fully automatic unified refueling device According to the periodic input instructions on the multi-function operating panel, the appropriate amount of refueling can be automatically performed, and the cumulative refueling amount can be confirmed, saving the time of manual refueling.
The weft automatic processing device (TAPO-E) is an automatic processing device researched and developed for weft yarns such as glass fibers and long fibers that are not easily broken.
Automatic Yarn End Processing Device (ABC) When replacing the weft yarn package, the automatic yarn end processing device will automatically push out the tail yarn of the yarn package being used and steadily transfer it to the next full yarn package. Therefore, time for exchanging empty bobbins is saved.
Multi-section beat-up ensures sufficient weft insertion time and achieves high-speed and stable weft insertion.
In addition to the left and right sides, the weaving selvage device is also equipped with scissors in the middle, which not only increases the added value of the fabric, but also allows the production of double-width fabrics.
IT functions TMS Toyota monitoring system and TTCS Toyota network and computer system.
Electromagnetic scissors The cutting time of the scissors can be adjusted through the multi-function operating panel.
The new ABS adds a weft yarn recovery function to the original braking function. This device can set the braking force through the multi-function operating panel according to the type of weft yarn. The action time is automatically controlled according to the flying state of the weft yarn, which plays its due role in preventing weft yarn breakage and saving energy consumption. In addition, gas threaded brakes improve operability.
Control system In order to target the future development of the weaving factory, the machine is fully equipped with new electronic control technologies such as a new color multi-function operation panel and a new high-speed CPU that can cope with Internet technology that greatly improves communication functions. Through the main control computer (32-bit/133MHz CPU), the operating console, weft feeder, hemming device, shedding, let-off and winding are controlled.
