< p > all along, the doffing mode of spinning roving machine has been repeatedly bent down to remove the full yarn and put it on the carriage.

If the roving machine is 120 spindles, it will be repeated 120 times. The action of 132 spindles will be repeated 132 times, then the air tube will be inserted into the equipment, and the labor intensity can be seen.

Therefore, roving truck has a very high probability of lumbar muscle strain.

< /p >

< p > CMT1800 thickness combined with intelligent full-automatic roving frame system is the representative of CNC generation spinning equipment.

To the set length, the Xialong stiffener automatically drops to the doffing position. After the doffing is ready, the reducer drives the Xialong ribs to move out to the front positioning switch position and the doffing rack starts to drop. The doffing rack falls down to fill the yarn, and the doffing frame rises until it is separated from the lower spindle bar. Then, the half spindle distance is turned to realize the alignment of the air pipe by means of the steel belt rotary device inside the doffer. Immediately after the doffing frame is lowered, the empty bobbin is released on the wooden pipe wheel; the doffing frame rises, and when the doffer rises to a certain height, the Xialong rib plate moves back to the rear positioning switch position, and the Xialong rib plate rises to the initial spinning position for a new round of spinning. The automatic doffing roving machine in the system can automatically realize the following action process under automatic mode: when spinning

< /p >

< p > the doffing parking action can be completed in 2 minutes at the fastest time, and the longest complex species will take only 3 minutes.

And other similar equipment, even in the experimental plant to complete the above action, also need more than 10 minutes, only this one can make spinning efficiency increased by more than 10%.

In addition, because of the concept of independent design of doffing mechanism, the maintenance and repair of the automatic doffing mechanism does not affect normal spinning, that is to say, the spinning process can be used to maintain the automatic doffing mechanism, reduce the stopping time of maintenance and improve the spinning efficiency.

< /p >

< p > doffing, ditches, ATC exchange success rate is the most important index to measure the performance of the automatic doffing roving machine.

After nearly ten years of groping and experimentation, the success rate of set universal equipment has reached nearly 100%, which has solved a series of problems and has made many invention patents.

An employee can operate more than 4 roving frames, and no matter whether the operator is tall or not, no need to bend over the yarn or yarn to solve the problem of roving workers prone to lumbar muscle strain.

< /p >

< p > in the traditional production mode, the roving is manually placed on the trolley after being doffed, and is pushed from the yarn carrier to the spinning process, which is used for the spinning of the spinning frame. However, < a href= "http://www.91se91.com/news/index_c.asp" > roving < /a > often causes fiber damage during the pportation process, thus affecting the spinning quality.

In the system, the yarn exchange manipulator can realize the automatic exchange of full tube roving and empty bobbin, and the air pipe enters the doffing frame to prepare for the next round spinning, and the full yarn is directly pported to the air solid yarn storage by the coarse and fine joint system.

< /p >

< p > < strong > "one key operation" brings convenience > /strong > /p >

< p > coarse and fine combined system makes the management of complex spinning process simple and easy to operate.

The "one button operation" can achieve automatic spinning and automatic conveying of roving according to the set process requirements.

< /p >

< p > spinning Rover only needs to press the yarn button, the system will be set according to the program process, and the bobbin with tail yarn will be automatically conveyed to the tail scavenging machine for cleaning, and the corresponding roving will be sent to the spinning frame.

Cleaning the tube and conveying the yarn can be carried out at the same time, which improves the production efficiency.

According to the actual production situation, the truck can press the chain moving button of the spinning machine freely to control the stopping position of the conveying chain and facilitate the yarn replacement.

< /p >

< p > coarse and fine combination system realizes multiple yarn library collective network control, uses modular program control, adopts PLC, fieldbus technology and networking communication system to monitor the supply and demand of roving in real time.

The application of the Internet of things technology to achieve full integration of logistics and information flow between the processes meets the informatization requirements of textile enterprises.

It can realize the intelligent connection of all roving machines, spinning frames and all the equipment of thickness and thickness, and collect, analyze and process all kinds of real-time information.

Issue instructions according to the production process and production management requirements to ensure the automatic operation of the whole system.

The system is equipped with standard network interface and can realize remote monitoring function.

Through the network communication system, the supply and demand situation of roving can be monitored in real time, and the yarn roving of roving to spinning can be omitted, which has changed the traditional management mode in the past, greatly reduced the labor cost and management cost.

< /p >

< p > Top any where network software is used for remote monitoring.

Through the data acquisition of each equipment, the field data of the whole system's operation and production status are pmitted to the monitoring computer to monitor the operation of all the automatic doffing roving machines and the coarse and fine equipment. The real-time monitoring and production process variety allocation are realized. The production status is recorded and counted, unified shift time control, unified management of production processes, automatic printing of reports, data exchange with enterprise ERP, equipment maintenance hints and so on.

< /p >

< p > the use of technology such as Internet of things, information flow technology, man-machine conversation technology has changed the form of production of enterprises, and realized the automation and intellectualization of spinning.

The soft touch human-machine interface is used to realize parameter setting, fault detection and operation monitoring. The operation is simple and the information and digitalization of control are realized.

The replacement of varieties is simple and clear. When changing new varieties, the whole system will run accurately by simply spinning varieties and spinning demand varieties through touch screens.

According to the set requirements, the conveying system conveyed the corresponding varieties from the intelligent yarn library.

< /p >

< p > each batch of a href= "http://www.91se91.com/news/index_c.asp" > roving machine < /a > roving is allocated to the specific track of the roving storage storehouse in the air.

The track code corresponds to the variety, and receives the approval and control of the control center. The whole thickness and joint system is controlled reasonably through the control center.

First, through software control, each conveyer chain control center is allocated a variety. Two, according to the color recognition function of the bobbin, the roving of each species is allocated to a kind of bobbin color. The color of the bobbin detected by the color sensor is determined, or the roving varieties are allocated and identified by RFID RFID technology.

< p > online automatic cleaning machine for tail yarn can carry out automatic cleaning of 8 ends at the same time. After cleaning the residual yarn, it can continue to be used. The special yarn remover has been cancelled, and the production efficiency has been greatly improved, and there is no waste of yarn.

At the same time, the system is also equipped with an automatic identification and screening system of bobbins, which is used to detect the bobbins which can not be cleaned up by human factors and can be identified according to the color of bobbins. The unqualified bobbins are filtered out by mechanical hands, and the qualified bobbins are exchanged from the spare yarn storehouse to ensure that the qualified rate of the bobbin is 100%.

In addition, the design concept of conveying chain cleaning, automatic cleaning of yarn library, conveying chain maintenance station solves the problem of cleaning and maintenance of chain and yarn library.
