Description
The double-layer rapier loom features that two layers or two pairs of weft-inserting rapier are installed on the loom, a shedding mechanism is used to form two layers of shed, and a special reed in the shape of Bu is installed. By adopting the technical scheme of the invention, the double-layer rapier loom can be reformed by reforming the original loom or the old loom on the basis of the existing shuttle loom and the rapier loom, and a new double-layer rapier loom can be manufactured by the modified design on the basis of the manufacturing of the existing loom and is used for double-layer weaving. The double-layer weaving technology can be used for improving the efficiency or the yield of the original loom by one time on the basis of the original loom by all the old machines or the new machines manufactured according to the characteristics of the invention, thereby achieving the purpose of obtaining the multiple increase of the economic benefit under the conditions of not increasing the occupied area and the factory buildings, not increasing the operation and management personnel and only investing a small amount of reconstruction funds.
The textile industry and the textile technology are the scientific and technological fields with a long history, the textile technology has been developed rapidly and vigorously for many years, in order to improve the production efficiency of the loom, the method of improving the speed of the loom is mostly adopted, various countries develop high-speed looms by investing a large amount of funds, novel high-speed and high-efficiency looms continuously appear, the speed limit of the shuttle loom is broken, the speed of the loom reaches more than 400 r/min, the weft insertion rate reaches 1000 m/min, and the rapier loom, particularly the flexible rapier loom, has the characteristics of simple structure, small occupied area, suitability for multi-color weft changing, wide applicability, high production efficiency, convenience for old loom transformation of the shuttle loom and the like, so the rapier loom becomes a machine type with the fastest development and the widest application in the novel loom, and forms worldwide rapier heat tide at present. However, such excellent types have been limited to single-shed single-layer weaving, and although rigid rapier looms have been of the double-shed double-layer rapier type, they have been used only for warp-pile type fabrics with raised warp yarns, and for non-warp-pile type fabrics, rapier looms having the features of the present invention, particularly flexible rapier looms and jacquard looms, and their double-layer weaving techniques, have not been precedent in the past.
In the past, jacquard fabrics for weaving weft yarn color changing, such as jacquard blankets, sofa cloth, decorative cloth, bedspread cloth, curtain cloth, silk satin and the like, are woven by using a single-shed shuttle loom or a rapier loom to match with a jacquard mechanism, because the jacquard mechanism and a heavy hammer are healed back, the improvement of the speed of the loom is limited, the speed of the loom is slow, the efficiency is low, because of the numerous and complicated components (such as a card, a cylinder, a cross needle, a lifting knife, a vertical hook and the like) of the jacquard mechanism, the action is slow, faults such as unhooking, malfunction, bad parts and the like are easy to generate, a huge lifting heavy hammer under the action of gravity is influenced by the gravity acceleration, when the lifting hook is descended, the vertical hook cannot be separated along with the positive descending of the lifting knife, the swinging and impact of the heavy hammer are caused, the lifting of the harness wire and the warp yarn cannot be timely interfered, the problems of unclear opening and unstable running occur, and the like, so that the speed, this is limited by its own conditions, and it is difficult to increase efficiency by increasing vehicle speed alone. In recent years, advanced countries have found that jacquard fabrics are woven on a rigid double-layer rapier loom with a low vehicle speed, so that the weft insertion rate or efficiency is doubled.
The non-jacquard flexible rapier loom technology in foreign countries is developed rapidly, in order to develop a novel high-speed high-efficiency loom, each country has to invest a large amount of capital, Swiss salad 500 type, light research cost is 3500 more than ten thousand dollars, Belgian Bicarnot GTM type and Italy TP500 type vehicle speed reach 400 r/min, however, the advanced looms cannot be popularized and promoted in China in a short period, because the looms are expensive, one imported loom needs to spend tens of thousands of dollars for foreign exchange, namely the TP500 type produced in Shanghai, each selling price is 16-18 ten thousand yuan, which is difficult to purchase by general manufacturers, moreover, most looms are provided with high-speed electronic technology, the technical degree is high, the general spinning technology and yarn quality in China are not suitable for the high speed of more than 300 r/min, the technical levels and quality of operators and managers are difficult to adapt in a short period, and the current situation of equipment and technical conditions of the loom manufacturing industry in China, the key parts with high precision can not be manufactured widely, therefore, under the existing condition of China, only a small amount of most advanced looms can be manufactured, but a large amount of wide work can be put on the new machine of the car blocking speed and technology in manufacturing and the motor transformation of the existing equipment, and the double-layer rapier loom and the weaving technology with the characteristics of the invention are particularly suitable to be adopted. Moreover, in order to accelerate the construction of the fourteen generations, the textile production needs to be doubled at the end of the century, a great problem of equipment updating and transformation exists, and only a method for gradually solving the problem of partial updating and partial transformation is a shortcut for the technical progress of the textile industry by converting a shuttle loom into a rapier loom and a double-layer rapier loom.
The invention aims to adapt to the national conditions of China, introduce foreign equipment as little as possible, spend less money, have high efficiency, are fast and have strong adaptability, develop a middle-speed high-efficiency double-layer rapier loom and a double-layer weaving technology which are unique to the characteristics of China, increase the weft insertion rate and the yield by times, increase the economic benefit by times and exceed the international advanced level.
For example, taking the weaving of acrylic jacquard blanket as an example, no matter what type of flexible rapier loom is used at home or imported at present, the single-shuttle-mouth single-layer rapier weft insertion is carried out, the speed is 120-130 r/min, the weft insertion rate is about 260 m/min, if double-layer weaving is carried out, under the condition of unchanged original technical conditions, the weft insertion rate can reach about 520 m/min, if the scheme is adopted, spring heald is used for replacing heavy hammer heald back, or heald frame is used for weaving plain fabric or decorative fabric, the speed can be increased to more than 160-200 r/min, the weft insertion rate can reach more than 640-800 m/min, if the double-layer weaving technology is popularized to the fabric capable of being woven by high-speed loom, the speed is more than 250 r/min, the weft insertion rate is more than 1000 m/min, the application range is wider, only the raw material and yarn count of the single-layer rapier loom are required to be suitable for weaving, The rapier loom can be suitable for double-layer rapier looms, and has all the advantages of single-layer rapier looms, such as popularization in the whole country, saving of a large amount of foreign exchange and fund for the country, creation of huge economic benefits and wealth, and great significance for promoting the technical progress of the textile industry in China.
The invention is characterized in that the 'halter' shaped profiled reed is assembled, double-layer weaving of non-warp fluffed fabric can be carried out on any double-layer shuttle loom and rapier loom, or double-layer weaving of non-warp fluffed fabric can be carried out by changing single-layer shed into double-layer shed, changing single-layer shuttle into double-layer shuttle, or changing single-layer rapier into double-layer rapier on the basis of the existing single-layer shuttle loom and rapier loom, and the double-layer weaving of non-warp fluffed fabric can be carried out by twisting the limitation that the double-layer shuttle loom and rapier loom can only be used for warp fluffed fabric in the past, so that the double-layer weaving of warp fluffed fabric can be widely applied to any fabric, namely when the 'halter' shaped profiled reed is not assembled, double-layer weaving of warp fluffed fabric can be carried out, and when the 'halter' shaped profiled reed is assembled, double-layer.
For the convenience of implementation, the technical scheme of the invention is combined with the reconstruction of each part, and the flexible rapier jacquard loom is taken as an example and is described by the embodiment and the attached drawings.
The improvement and characteristic of the shedding mechanism are that the single shuttle mouth is changed into double shed, namely the mode of improving the heald and the lifting heald, the heald can adopt a special double-eye heald or a deviated eye heald, and two deviated eye healds replace one double-eye heald. The upper and lower heddle eyes of the double-eye heddle penetrate into the upper and lower layers of warp yarns respectively, the eccentric heddle is the warp yarn of which the upper and lower heddle eyes penetrate into the upper and lower layers respectively, the use amount of the heddle can be reduced by half by using the double-eye heddle, the distance between the two heddle eyes of the double-eye heddle is determined according to the opening height and is generally 5-10 mm larger than the opening height, so that the lower piece of warp yarn of an upper layer opening with large warp density and the upper piece of warp yarn of a lower layer opening keep a little distance, but for the warp yarn with small warp density such as a blanket fabric, the distance between the two heddle eyes can be smaller, namely about 80 mm. Therefore, the heddle eye distance of the double-eye heddle and the heddle eye distance of the eccentric heddle are serialized into 80 mm, 90 mm, 100 mm, 110 mm and the like so as to adapt to different shedding mechanisms. The double-eye harness and the harness of the embodiment are shown in figures 1 and 2, and the formation of the double shed is shown in figure 3.

The distance between the upper cloth fell and the lower cloth fell is about 3.5 mm, and the height of the upper cloth opening and the lower cloth opening in the reed part is about 55 mm when the bent shaft is in the back center.
The improved beating-up mechanism features that single-layer beating-up is changed into double-layer beating-up, and a shuttle moving plate is provided for the upper rapier, i.e. a profiled reed in the shape of Bu (a Chinese character) is used and the upper part of the reed seat is raised according to the height requirement of the reed.
In order to realize the weaving of the double-layer rapier, a condition must be created for the operation of the upper and lower double-layer rapier, particularly the upper rapier, the lower rapier operates by using a shuttle-moving plate on a sley as a bearing surface, the upper rapier also has the bearing surface, the bearing surface is provided by ground warps with very high tension on the double-layer rapier loom with fuzzed warps, and the upper rapier can stably pass through the upper rapier by the upper-layer open-ended lower warps with very high tension. The invention is characterized in that a reed in a shape of Bu' is assembled to provide a shuttle walking plate or a sword walking track for the smooth and firm upper sword running, thereby realizing double-layer weaving. The Bu-shaped profiled reed is shown in the attached drawing.
FIG. 4 is a schematic view of a Bu-shaped profiled reed.
FIG. 5 is a schematic view of a reed with a sword-moving rail.
FIG. 6 is a schematic view of the reed installation and beat-up positions of the "halter" type.
In figure 4, 1 is a straight reed, 2 is a "halter" reed, which is a special reed with a shuttle-moving plate bearing surface in the reed, 3 is a bearing surface, 4 is a reed, and 5 is a shuttle-moving plate. The manufacture of the reed in the shape of Bu is that the carbon structural steel is firstly rolled into straight reed blades 1 according to the size of the reed blades 1 (the length, width and thickness of the two reed blades are the same, the size is determined according to the size of the reed, the two reed blades in the embodiment are shown in figure 4), a pre-made stamping die is used for stamping a medium carbon structural steel plate (the thickness is 0.6-1.0 mm and is determined according to the reed number) into Bu-shaped reed blades 2, then the reed blades 1 and the reed blades 2 are matched according to the proportion of 5: 1, 8: 1 or 10: 1 according to the reed number requirement and are arranged in the length direction of the whole reed, all reed blade bearing surfaces are arranged in a straight line, then a blank body of the Bu-shaped reed is manufactured according to the conventional reed manufacturing method, then an organic glass or polyvinyl chloride thin plate with the same length as the reed and the same thickness of 3-4 mm or a thin steel plate or a thin plate with the thickness of 1-2 mm is welded on the bearing surface, the reed shuttle-moving plate has 94-98 deg. obtuse angle with reed surface, 94 deg. width of shuttle-moving plate, 60 mm distance between the shuttle-moving plate and the lower edge of reed dent, and reed number determined based on the fabric design.
For adapting to the high-speed flexible rapier loom, the high-speed flexible rapier loom is changed into double-layer weaving, for example, TP 300-500 type rapier loom, the original machine sley shuttle-moving plate is changed into a groove-shaped rapier track frame, one is about every 40 mm, therefore, when the single-layer rapier is changed into the double-layer rapier, a group of groove-shaped rapier track frames are additionally arranged on the upper shuttle-moving plate, one is about every 40 mm, as shown in figure 5, 1 is a thin steel plate shuttle-moving plate, 2 is a rapier-moving track frame welded on the shuttle-moving plate, and 3 is a rapier-moving groove, which is consistent with the rapier-moving grooves of the rapier-moving tracks on both sides of the upper shed.
The Bu-shaped profiled reed is suitable for any type of shuttle loom and rapier loom for double-shed double-layer weaving, is particularly suitable for flexible rapier loom and jacquard loom, and has no precedent in the past when the Bu-shaped profiled reed is adopted for double-layer weaving.
The use of a 'hal' shaped profiled reed is shown in the attached figure 6 when the reed is arranged on a sley, wherein 1 in the (A) is a sley seat foot, 2 is a reed cap, 3 is the reed, 4 is a lower shuttle plate, 5 is an upper shuttle plate, 6 is sley wood, the lower shuttle plate and the reed form an acute angle of about 88 degrees, the size of the acute angle is determined by the height of a position line of a lower warp, and the distance between the upper shuttle plate and the lower shuttle plate is about 55 mm. In the figure (B), 1 is a lower rapier-walking track frame, 2 is an upper rapier-walking track frame, and 3 is a rapier-walking groove.
The improvement and the characteristic of the weft insertion mechanism are that a single-layer rapier is changed into a double-layer rapier, and the weft insertion mechanism has the following forms:
a weft-inserting mode of double-layer flexible rapier is characterized by that it utilizes the rapier-conveying mechanism of original single-layer flexible rapier loom (including one modified from shuttle loom) and original rapier-conveying gear to drive upper and lower two flexible rapier which are overlapped, and two rapier still use original rapier box (shared), only the inner track of box is deepened, after the rapier is taken out of box, the rapier can be fed into its own track, the upper rapier can be fed into upper shed rapier-walking track, and the lower rapier still can be moved according to original lower rapier-walking track, so that it is a double-layer flexible rapier weft-inserting mechanism, and the tail ends of two flexible tapes are firmly fixed together by means of riveting method, when the rapier-conveying gear is used to drive upper rapier tape to synchronously run, and because the track after the upper rapier is taken out of box has upward bent portion, its length is determined by the condition of two rapier heads of weft-feeding and weft-connecting, the transmission mode needs to deepen the track in the sword box to accommodate the lower two sword belts, and the two sword belts can also have thick roots (bear power) and thin roots, or the lower roots are nylon belts and the upper roots are thin steel belts.

The transformation mode is wide in adaptability, is suitable for single-layer flexible rapier looms (such as single-layer rapier jacquard looms transformed from H213 type jacquard looms) transformed from original shuttle looms, is also suitable for single-layer flexible rapier looms (such as rapier looms of GN721, 722, LT102, AC2/S, SM92, TP 300-500 types and the like), has few transformation parts, small investment and easy implementation, is a better innovation mode for improving the efficiency of the existing single-layer flexible rapier looms, and is also a simple and convenient mode for transforming the shuttle looms.
The double-layer flexible steel belt rapier weft insertion mode is characterized in that two steel belts are fixed on a rapier conveying arm of an original single steel belt transmission mechanism and run simultaneously. In operation, the upper and lower belts enter and exit the upper and lower sheds with their own tracks, a feature of which is shown in fig. 10.
Fig. 10 is a schematic diagram of a double-layer steel belt transmission mode.
In the figure, 1 is a rapier conveying arm, 2 is an upper layer and a lower layer of two steel belts, 3 is an upper layer and a lower layer of two rapier heads, 4 is a steel belt guide wheel, 5 is a steel belt guide rotor, and 6 and 7 are upper layer and lower layer steel belt guides or tracks.
The transmission of the steel belt of the weft insertion mechanism is driven by the rotation of the rapier conveying arm, the rotating angle of the rapier conveying arm determines the moving distance of the rapier head, and the rotating angle cannot be larger than 2 pi. The weft insertion mechanism and the beating-up mechanism of the loom are separated, cam beating-up is used, the weft insertion mechanism does not move along with a sley, and the eccentric sliding block type steel belt loom and the RJZ-220 type steel belt loom belong to the category. The single-layer rapier of the loom is changed into a double-layer rapier very conveniently, is simple and feasible, has small investment, and only needs to add a track of an upper steel belt and an upper steel belt on the original basis, the added steel belt is fixedly connected with the original steel belt at one end of a rapier conveying arm, and the weft insertion rapier and the weft receiving rapier are the same in mechanism.
