Warping: Warping is defined as the parallel winding of yarn from a cone or cheese package onto a warp beam. It is needed to confirm that the warp beam is made from good waro yarn otherwise weaving performance will be hampered. So it needs to require to provide a good warp beam. Faulty weavers beam is one of the causes of wastage in the weaving section.

Typically, looms use a shuttle to weave the weft thread through the shed of warp threads. However, the rapier isn`t that type of loom. It uses a rapier or small finger-like projections to carry the weft thread across the warp thread. There are two types of rapier looms. One is called a single rapier and the other is called a double rapier. In the single rapier loom, one rapier extending the length of the shed is used. In the double rapier, two rapiers exist. One rapier carries the weft thread halfway across, where it is met by the other rapier that takes it to the end.

rapier loom, a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by fingerlike carriers called rapiers. One type has a single long rapier that reaches across the loom`s width to carry the filling to the other side. Another type has two small rapiers, one on each side. One rapier carries the filling yarn halfway through the shed, where it is met by the other rapier, which carries the filling the rest of the way across the loom.

Numerical dynamic simulation test and key technology study for a type of rapier loom have been done by use of virtual prototype technology.Geometrical model was made by SolidWorks with assembly followed and interference checked.Physical virtual prototype was built under ADAMS Platform.An all round dynamic simulation test was carried out at different speeds and working conditions.Dynamic stress and optimization of parts at high speed were analyzed by collaborative simulation of ADAMS and ANSYS.This provides technical support for increasing speed and improving dynamic performances of the rapier loom and for developing new rapier loom products as well.

Introduction and daily maintenance and maintenance Since my country's accession to the WTO, the textile industry has ushered in a development climax. From the perspective of the fabric market, it is the domestic market and the international market. The requirements are getting higher and higher, and the variety of designs and colors are changing faster and faster, so that the loom has stronger adaptability to fabrics and higher production efficiency. At present, most of the rapier looms in our country are at the low and medium level, with a running speed of 300 40or/min or so. The performance of a loom is good or bad, and the level of mechanical parts and electrical control is an important indicator. The electrical system of the rapier loom is mainly composed of the control part and the detection part. At present, the domestic loom situation mainly reflects the following aspects. 1 control part The control part has two forms of single-chip control and PLC control. These two forms have their own characteristics. The control cost of the single-chip microcomputer is low and the production is easy. The disadvantage is that the stability, reliability and anti-interference ability are poor, the quality of electronic components cannot be guaranteed, and the maintenance cost of manufacturers and users is high. The biggest feature of PLC control system is high reliability and stability, strong anti-interference ability. Many of its functions are realized by software technology, which can reduce the use of peripheral hardware and reduce the probability of failure. Usually, PLCs have a normal operating life of 50,000 to 100,000 hours. At present, there is no suitable PLC product in China. The market is basically monopolized by foreign manufacturers, and the cost is higher than that of single-chip microcomputers. be high. However, considering its reliability and stability, PLC is selected. There are more and more manufacturers. 2. The detection part of the control system The detection element provides signals to control the loom, and the function of the detection element is very important. Proximity switches are often used as detection elements in looms. The reliability of proximity switches in long-term high-speed operation is an important issue. Occasionally a mistake will lead to defective fabrics. The solution to this problem is to use a rotary photoelectric encoder, which can quantify the mechanical position of the machine into an angle, and the PLC angle controls the loom. The rotary photoelectric encoder is an optoelectronic device with strong anti-interference ability, which can work in different environments and has a lifespan of more than 10 billion times. 3-function PLC is superior to single-chip control in terms of reliability and stability, and its achievable functions are also stronger than that of single-chip microcomputer. These functions are divided into basic functions Auxiliary functions, management functions. 3.1 Basic functions Basic functions include electronic color selection (8 colors, more than 3000 wefts); warp breaking, weft breaking, and heavy weft parking; automatic weft searching (6 kinds of weft finding programs); fault parking light alarm; position setting (normal Parking space, fault parking space, weft detection area setting). 3.2 Accessibility (1) Chinese display interface, intelligent man-machine dialogue, can display various parameters of the loom under different conditions. During normal operation, the current loom running angle, running speed, fabric serial number and fabric color number are displayed. When parking, the reason for parking and the current angle are displayed. (2) The fault self-diagnosis function is divided into two categories: soft and hard faults. Soft faults: warp breakage, weft breakage, heavy weft; hard faults: brake failure (causing inaccurate angles) dobby contact failure (causing the weft finding cannot be completed) clutch failure (causing the loom cannot be started). The above faults, in addition to the Chinese display on the interface, are also accompanied by light reports. (3) The system test function (non-running state) can detect jog, start, normal stop, forward and reverse weft searching, warp breakage, weft breakage, and heavy weft, which is convenient for loom inspection, maintenance and fault diagnosis. (4) Safety protection function. If the loom does not move within three minutes, the color selector will automatically power off. Press jog or start, and the color picker automatically restores power. The hardware design should have the effect of absorbing the arc (spark) generated by braking to eliminate the fire hazard. Power-off data protection in various operating states, and can continue to operate before power-off after power is restored. (5) Diversified color selection program settings. The color selection program of the PLC electronic control system can be set on a single set using the man-machine interface on the control cabinet. Complex programs or multiple loom program settings can be performed with a dedicated laptop computer (such as SEMENSMOBIC). Put the required program MOBIC in advance It can be compiled, stored and called directly when needed. Network PC is also available on-board. 3.3 Management functions (1) The system has built-in records of the output and production efficiency of each of the four shifts. The number of warp breaks, weft breaks, and rewefts can be queried at any time to call the set cloth length (such as 1km), and the output will stop when the set value is reached, and the length will be replaced. axis and reset to continue production. In the running state, it can be used for adding and subtracting weft to facilitate color matching. 3.4 Network management and control Using PP network, all looms can be networked, and a PC can monitor the entire production situation and read production data. At the same time, it can also transfer instructions down to modify the production process parameters. Hook up the INTERNET network, can carry on the long-distance diagnosis to the loom. 4 Comprehensive comparison Based on the analysis of the production status of domestic textile machinery factories, such as Jiangsu Gaochun, Zhejiang Titan, Shanxi Jingwei, Wuxi Longli, etc., except for Zhejiang Titan to absorb the original SM93 circuit board function and make a small change and integrate it into two large circuit boards, All other manufacturers use PLC as the core and use the rotary photoelectric encoder as the detection element as the main electronic control device, which not only simplifies the hardware design, reduces the failure points, but also improves the reliability and stability of the system. The system design is fully mature and represents the development direction of rapier looms. 5 Rapier Loom The development trend of electrical control investigates and analyzes the application manufacturers of jianji looms, and we find that: users require looms with high reliability and stability, and higher expectations for future looms, i.e. high speed The running speed of the rapier loom is more than 600r/min, giving full play to the advantages of the rapier loom. At present, such high-grade rapier looms have been successfully trial-produced in China. The running speed has been doubled, and the electrical control requirements are higher. It is equipped with electronic dobby, electronic let-off, and electronic coiling. The price is lower than imported air-jet looms. , the production capacity is close to the air-jet loom. Such high-grade rapier looms have become the latest development trend in the textile machinery industry. It is believed that in the near future, high-speed rapier looms will become strong competitors of air-jet looms in the domestic market. At present, there is still a big gap between the level of looms in our country and developed countries abroad. How to deal with the increasingly fierce international competition is the top priority of every manufacturer. With backward technology and no backward products, we will continue to carry out technological innovation to be invincible. place

1. The composition method is different: the large rapier adopts a separate reed seat, which is fast. Small rapiers use non-split reeds, which are slower. 2. The forming process is different: the small rapier is transformed from an old-fashioned shuttle loom, the structure is simple, and the fabric is also very simple. Large rapiers are mostly imitated foreign imported looms, which are suitable for different fabric varieties after their own improvement. 3. Different production efficiency: the output of small rapier fabric is not as much as that of big rapier, of course, the quality is not as good as that of big rapier, and the price is cheap. Large rapiers have high rotation speed and high output, but the price is relatively high.

1. When new jute rapier loom start running, should be check the gap between each gears and check the screw degree of tightness. 2. Refueling all the oil holes, bearings, let off and take up worm and gear (lubricating oil mixed with engine oil). Note: lubricating oil should be high-temperature lithium base oil. 3. Jute rpaier loom will be running 24 hours/day, at first month, refueling 8 hours/time, 3 times/day. One month later, refueling 12 hours/time and 2 times/day. 4. When finish first beam, should be refueling all bearing (lubricating oil). Refueling after one month and refueling 3months/time. 5. Check in time all the screw degree of tightness makes sure the machine running smoothly.

Rapier loom is the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation and high-efficiency production of shuttleless looms, its active weft insertion method has strong variety adaptability. It can adapt to the weft insertion of various yarns, and the rapier loom also has obvious advantages in multi-color weft weaving, and can produce yarn-dyed products with up to 16-color weft yarns. With shuttleless looms replacing shuttle looms, rapier looms will become the main production machine for woven fabrics.

Fabric distinction To judge whether the fabric is a sword-woven fabric or an air-jet fabric, it can be seen from the weave of the fabric edge: (1) Usually the polyester-cotton thread is rapier (overlock device), and the filament is air-jet weaving (planetary gear device). (2) Air-jet double-split fabric with thread on one side and filament on the other. (The middle is the locking device, and the two sides are equipped with planetary gears). (3) Rapier double-open fabric, both side yarns are polyester-cotton threads (both are overlock devices). Loom distinction Rapier looms: Use rigid or flexible rapier heads, belts to hold and guide the weft. In addition to being suitable for weaving plain and textured fabrics, rapier looms are characterized by easy color changing, suitable for multi-color weft fabrics, and are suitable for the production of yarn-dyed, double-layer fleece fabrics, terry fabrics and decorative fabrics. Air-jet loom: The weft yarn is pulled by the compressed air jet, and the weft yarn is taken through the shed. The biggest feature of air-jet looms is fast speed and high labor productivity. The advantages and disadvantages of grey cloth (1) The grey fabric produced by jet machine generally has many varieties of fine-count yarns and high grades of grades, mainly light and thin fabrics; rapier machines generally have many varieties of coarse-counted yarns with low grades of grades, mainly heavy fabrics. (2) From the point of view of equipment, jet and rapier are nothing more than weft insertion. (3) For grey fabrics of the same organization, the cost of raw materials is the same, and the weaving cost is lower. For example, for twill, the maximum speed of the jet can reach more than 800 rpm, the rapier is only about 180-200 rpm, and the jet-blocking personnel can watch 10-12 units per person. And up to 4-6 arrow shafts. The commonality and heterogeneity of fabrics Commonality: All are burrs and can be of the same specification. Heterosexual: On the premise of the same yarn count and specifications: The jet gram is slightly lighter. The flatness of air-jet flat grey cloth is better than that of rapier production. The shrinkage rate of air-jet loom fabrics will be larger accordingly. Air-jet yarn is better than rapier.

Rapier Looms are becoming more and more widespread in people's lives, and rapier looms are a type of shuttleless looms. Thanks to the good adaptability and low price of rapier accessories, it has always been in a leading position. It is widely used in yarn-dyed weaving, silk weaving, wool weaving and other industries, and is the most common loom. Next is how the rapier accessories work: 1. Working principle The weft selection signal device of the accessories of the rapier loom sends a command signal according to the weft color cycle designed by the process to complete the weft mixing work through the weft selection rod. The weft selection device technology relies on computer technology, uses computer to select weft, and controls the instruction through the computer, so as to improve the work efficiency of weft selection and improve the quality of spinning. 2. Classification of rapier looms Rapier looms are divided into single rapier looms and double rapier looms according to the number of rapiers. The single rapier guides the weft yarn from one side of the shed to the other, for retrofit narrow looms. Due to the simple structure of the single rapier loom accessories, they cannot be widely used, so they are rarely used. The double rapier is completed by the rapiers located on both sides of the shed, so that the door width of the loom can be increased, and it is often used. Rapier loom accessories are only one type of looms. For other looms, it is necessary to analyze the specific situation and use different processes to select different looms. Thereby improving production efficiency and improving economic benefits.
