Application of Delta Automation Products on Spinning Machines
1 Introduction
The spinning process is the last step of yarn forming. The roving is further drawn 30 to 50 times and twisted, and spun into a spun yarn having a certain number and conforming to relevant quality standards for use in twisting, weaving or knitting. The spinning frame has low speed operation, high speed operation, blowing and suction, and doffing. The doffing is divided into automatic doffing and midway doffing (pause work), and automatic doffing is divided into long doffing and regular doffing. The automatic doffing method, the doffing time and the length can be set and can be maintained after power down. The production scale of the textile mill is expressed by the total number of spindles of the spinning frame; the yarn yield is the basis for determining the number of each process; the quality level of the yarn, the consumption of raw materials and other indicators, labor productivity, etc. are the embodiment of the technical and management level. Therefore, the spinning process plays an important role in the textile mill. Due to the low precision, poor safety and high failure rate of traditional electrical control equipment, it has gradually been replaced by modern automatic control equipment. Nowadays, the automation control of spinning frame equipment is getting higher and higher. It will be applied to different kinds of industrial automation products according to different equipments, such as: man-machine interface, PLC, frequency converter, servo system, encoder, temperature control instrument, etc. . Customers can often choose the appropriate equipment to build the control system according to the different control objects.
Delta Electromechanical has been able to provide customers with a series of products such as PLC controller, temperature controller, counter, man-machine interface, variable frequency drive, servo drive and numerical control system, which can provide customers with perfect and reliable mechatronic solutions. This paper is based on Delta's automation products to achieve effective control of the ring spinning machine, which is worthy of reference and promotion.

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: <16 ㎡; Daily operating time: >2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
