Abstract

This invention proposes a direct-drive beat-up mechanism, a loom, and a loom control system. The direct-drive beat-up mechanism includes a reed assembly and a drive module. The drive module includes at least one linear motor, which provides the primary power source for the linear reciprocating motion of the reed assembly. Each linear motor includes a stator and a mover, with the mover slidingly engaged with the stator. The end of the mover is connected to the reed assembly. This invention directly connects the mover to the reed assembly, eliminating intermediate transmission mechanisms, reducing power loss, and facilitating better control of the beat-up motion by the loom control system. It also reduces system vibration and noise. By decoupling the traditionally strongly coupled beat-up motion with the spindle motion, the complexity of the system structure is reduced, the load on the spindle is lessened, and higher loom speeds are possible, leading to more efficient and convenient production, wider adaptability to different fabric types, and improved fabric quality.

Description

Technical Field

[0001] This invention relates to the field of textile weaving technology, and in particular to a direct-drive beat-up mechanism, a loom, and a loom control system. Background Technology

[0002] Currently, traditional looms mainly consist of five mechanisms: shedding mechanism, direct-drive beat-up mechanism, warp feed mechanism, crimping mechanism, and water jet mechanism. Among them, the direct-drive beat-up mechanism is mainly used to push the weft yarn introduced into the shed by the weft insertion mechanism toward the weft hole, thereby forming a stable fabric.

[0003] The power source for the direct-drive beat-up mechanism of traditional looms can only come from the main shaft. The main shaft motion is converted into reciprocating oscillation through mechanisms such as crankshaft connecting rod and conjugate cam. The operation state of the direct-drive beat-up mechanism can only be achieved by adjusting the operation state of the main shaft. However, the motion transmission between them is nonlinear and strongly coupled. Therefore, the direct-drive beat-up mechanism of traditional looms has many drawbacks in terms of application, such as high variety adaptability, unstable weaving, high noise, and is not conducive to high-speed loom operation. It also has high limitations in terms of process adjustment of fabric quality. Summary of the Invention

[0004] The main objective of this invention is to provide a direct-drive weft insertion mechanism that decouples the weft insertion motion from the spindle motion, directly drives the reed assembly to achieve parallel weft insertion, thereby solving at least some of the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention provides a direct-drive beat-up mechanism comprising:

[0006] Steel reed components; and

[0007] The drive module includes at least one linear motor, which provides the active power source for the reed assembly to perform linear reciprocating motion; wherein each linear motor includes a linear motor stator and a linear motor mover, the linear motor mover is slidably engaged with the linear motor stator, and the end of the linear motor mover is connected to the reed assembly.

[0008] In one embodiment, the drive module further includes a first connector for connecting the linear motor stator and the loom frame.

[0009] In one embodiment, the first connecting seat and the linear motor stator are an integral structure.

[0010] In one embodiment, the plane on which the first connecting seat is located is parallel to the center plane of the linear motor actuator.

[0011] In one embodiment, the distance between the linear motor and the reed assembly is less than a preset threshold.

[0012] In one embodiment, the linear motor actuator is integrated into the reed assembly.

[0013] In one embodiment, the direct-drive beating mechanism further includes a second connecting seat for connecting the reed assembly and the linear motor mover;

[0014] The first end of the linear motor mover is connected to the second connecting seat, and the second end of the linear motor mover is in sliding engagement with the linear motor stator.

[0015] In one embodiment, the linear motor stator is disposed on at least one side of the reed assembly, the linear motor mover moves horizontally, and the second connecting seat includes a connecting portion and a fixing portion connected together. The connecting portion is connected to the linear motor mover, and the fixing portion is connected to the reed assembly.

[0016] In one embodiment, the direct-drive beating mechanism is provided with a plurality of linear motors, and the plurality of linear motor actuators are connected to the reed assembly through at least one second connecting seat, and the at least one second connecting seat is provided with a plurality of fixing parts;

[0017] Wherein, at least a portion of the fixing part is provided on both sides of the adapter part, and / or at least a portion of the fixing part is provided on the surface of the adapter part away from the linear motor actuator.

[0018] In one embodiment, the adapter is an integral structure, and the fixing part is disposed on the adapter and connected to the reed assembly;

[0019] And / or, the second connector is an integral structure;

[0020] And / or, the fixing part is provided with reinforcing ribs.

[0021] In one embodiment, the linear motor includes: a cylindrical linear motor, a flat linear motor, or a U-shaped linear motor.

[0022] The present invention also proposes a loom, the loom comprising a frame and a direct drive beat-up mechanism as described in any of the above claims, wherein the stator of the linear motor in the direct drive beat-up mechanism is fixedly connected to the frame.

[0023] The present invention also proposes a loom control system, which is applied to the loom described in the preceding claim, characterized in that the loom control system comprises:

[0024] The interaction module is equipped with a human-computer interaction interface;

[0025] The detection module is communicatively connected to the interaction module, and the detection module is equipped with a sensor, which is located on the loom.

[0026] The main control module is communicatively connected to the interaction module and the detection module; and

[0027] A drive control module is electrically connected to the drive module and communicatively connected to the main control module and the detection module.

[0028] This application uses a linear motor as the main power source for the linear reciprocating motion of the reed assembly. Its advantages lie in replacing the complex weft-beating mechanism with a direct-drive linear motor, resulting in a simpler structure and greater suitability for high-speed loom operation. Furthermore, the force-displacement and current characteristics of a linear motor are almost linear, allowing for more linear and flexible control of the reed assembly to achieve the weft-beating motion. This application directly connects the linear motor mover to the reed assembly, eliminating intermediate transmission mechanisms and directly driving the reed in linear reciprocating motion. This reduces power loss and facilitates better control of the weft-beating motion by the loom control system, thereby achieving efficient digital and electronic loom control and significantly reducing system vibration and noise.

[0029] In this way, the traditional weft-beating motion, which is strongly coupled with the main shaft motion, is decoupled, simplifying the structure and greatly reducing the complexity of system integration. This also reduces the load on the main shaft, which is beneficial for high-speed looms. Furthermore, this setup eliminates the need to replace the direct-drive weft-beating mechanism or adjust the main shaft; simply adjusting the parameters of the linear motor allows for convenient control of the weft-beating stroke and force to adapt to different fabric types, making production more efficient and convenient. Therefore, the direct-drive weft-beating mechanism proposed in this application can adapt to various air-jet and water-jet looms with traditional asynchronous main shaft drives and direct-drive main shaft drives, as well as rapier looms, truly achieving wider product adaptability. It can also compensate for some of the start-up defects of the loom, greatly improving fabric quality. Attached Figure Description

[0039] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0043] like Figure 1As shown, traditional looms currently mainly include a shedding mechanism, a beat-up mechanism, a warp feed mechanism 230, a winding mechanism 270, and a water-jetting mechanism. The warp feed mechanism 230 drives the warp beam to release the warp yarns, and the winding mechanism 270 winds the woven fabric onto the winding beam. The heald frame 240 moves in layers, allowing the warp yarns passing through the center eye of the healds to form a shed, ensuring that the weft insertion mechanism 250 can smoothly pass the ejected weft yarns through the shed. The beat-up mechanism beats the weft yarns onto the fabric surface to form the weave. All these mechanisms work together in a specific sequence within a certain angle range of the main shaft 210, following the rotation cycle of the main shaft 210, to complete the weaving operation.

[0044] The main function of the beat-up mechanism is to push the weft yarn introduced into the shed by the weft insertion mechanism 250 towards the weft insertion point, thereby forming a stable fabric. Traditional loom beat-up mechanisms are mainly divided into four-bar beat-up mechanisms, six-bar beat-up mechanisms, and conjugate cam beat-up mechanisms. For example... Figure 1 The diagram shows a traditional four-bar linkage beat-up mechanism for a loom. Its primary power source can only come from the main shaft 210. A crankshaft four-bar linkage converts the continuous rotation of the main shaft 210 into the reciprocating oscillation of the beat-up mechanism. In other words, the strong coupling design between the traditional beat-up mechanism and the main shaft 210 necessitates that the periodic motion of the main shaft 210 be converted into the periodic reciprocating motion of the reed assembly 50 via a mechanical transmission mechanism such as a crankshaft linkage or conjugate cam mechanism.

[0045] Therefore, traditional weft insertion mechanisms on looms have the following shortcomings in application:

[0046] (1) High variety adaptability. For a loom 200 that has been installed and debugged, the size of the weft insertion mechanism and the weft insertion swing angle stroke are fixed. The weft insertion motion state is strongly coupled with the motion of the main shaft 210. One weft insertion mechanism can only adapt to a specific range of fabric varieties, and it is difficult to adapt to the variety by adjusting the weft insertion mechanism. This limits the variety adaptability of a single loom 200.

[0047] (2) It has high limitations in process adjustment and fabric quality adjustment. Common problems of fabric defects during operation are related to the weft force output state of the weft-beating mechanism. The operating state of the traditional weft-beating mechanism can only be achieved by adjusting the operating state of the main shaft 210210. The debugging is difficult and inefficient. It is complicated by many factors and is not conducive to operation.

[0048] (3) The periodic oscillation of the weft insertion mechanism causes obvious periodic fluctuations in the movement of the main shaft 210, which brings many adverse effects to stable weaving;

[0049] (4) The periodic reciprocating oscillation characteristics of the weft striking mechanism, due to the dead point effect of the crankshaft connecting rod, when the reed is at the front and rear dead points, it has a large acceleration, which introduces a large horizontal vibration impact to the 200 frame of the loom, which has a large impact on the structural reliability, especially the life of the main shaft 210, and is not conducive to the high speed of the 200 loom.

[0050] (5) The periodic reciprocating motion of the weft insertion mechanism is the main component of the equivalent load fluctuation, resulting in serious vibration and noise problems for the whole machine.

[0051] In view of this, in order to decouple the weft insertion motion from the main shaft 210 motion and directly drive the reed assembly 50 to perform parallel weft insertion, the present invention provides a direct drive weft insertion mechanism 100.

[0052] Reference Figures 1 to 6 In some embodiments of the present invention, the direct-drive weft insertion mechanism 100 may include a reed assembly 50 and a drive module. The drive module may include at least one linear motor 10, which provides a power source for the reed assembly 50 to perform linear reciprocating motion. Each linear motor 10 may include a linear motor stator 11 and a linear motor mover 13, which slides with the linear motor stator 11. The end of the linear motor mover 13 is connected to the reed assembly 50.

[0053] In one embodiment, the direct-drive weft insertion mechanism 100 proposed in this application drives the reed assembly 50 to achieve parallel weft insertion via a drive module independent of the main shaft 210. Specifically, the loom 200 is provided with a frame, and all mechanisms of the loom 200 are mounted on the frame, with each mechanism working together to achieve the weaving operation. In this embodiment, the drive module can also be mounted on the frame. The drive module includes at least one linear motor 10, and mainly drives the reed assembly 50 to perform linear reciprocating motion through a linear motor mover 13 that is movably coupled with the linear motor stator 11. Understandably, the direction of motion of the linear motor mover 13 is consistent with the direction of the warp threads, so that the reed assembly 50 can continuously push the weft threads led out by the weft insertion mechanism 250 into the weft inlet.

[0054] Optionally, refer to Figure 3 and Figure 4The linear motor mover 13 is a rod-like structure, and a linear channel 11a is provided through the linear motor stator 11. The linear motor mover 13 is movably disposed within the linear channel 11a and reciprocates relative to the linear motor stator 11 along the linear channel 11a. In this embodiment, the outer contour of the linear motor stator 11 is generally block-shaped or cylindrical, and it is fixedly connected to the frame. The linear channel 11a is a hollow passage, and the wire windings inside the linear motor stator 11 surround the linear motor mover 13. Depending on the actual weft insertion stroke, the linear channel 11a can pass through the linear motor stator 11 along the direction of the warp threads so that the linear motor mover 13 can pass through the linear motor stator 11, resulting in a longer weft insertion stroke; or, the linear channel 11a can be disposed within the linear motor stator 11, and the length of the linear motor stator 11 can be adjusted to suit the weft insertion stroke. When alternating current is applied to the windings inside the stator 11 of the linear motor, a traveling wave magnetic field is generated within the linear channel 11a. The mover 13 of the linear motor, under the influence of this traveling wave magnetic field, will induce an electromotive force and generate a current. This current interacts with the magnetic field to produce an electromagnetic thrust. With the stator 11 of the linear motor fixed, the mover 13 of the linear motor will move relative to the stator 11 along the linear channel 11a.

[0055] Of course, in other embodiments of this application, the linear motor 10 may also adopt a flat plate type, U-shaped type, or other configuration forms, which will not be limited here.

[0056] In one embodiment, the drive module may use a linear motor 10 as the sole power source; in another embodiment, the drive module may use a linear motor 10 as the main power source and a drive method including but not limited to ball screws as an auxiliary power source, with the main power source and the auxiliary power source working together to drive the reed assembly 50 in linear reciprocating motion.

[0057] Specifically, based on the above-mentioned form of using a ball screw as an auxiliary power source, the drive module may also include a rotary motor, a ball screw shaft, and a ball screw nut. The ball screw shaft is connected to the output end of the rotary motor, the ball screw nut is connected to the ball screw shaft, and the reed assembly 50 is connected to the ball screw nut. The rotary motor drives the ball screw shaft to rotate, so that the ball screw nut drives the reed assembly 50 to move along the axial direction of the ball screw shaft.

[0058] Understandably, the primary power source and the secondary power source can be synchronized.

[0059] This application uses a linear motor 10 as the main power source for the linear reciprocating motion of the reed assembly 50. Its advantages lie in replacing the complex weft-beating mechanism with a direct-drive linear motor 10, resulting in a simpler structure and facilitating higher speeds for the loom 200. Furthermore, the force-displacement and current characteristics of the linear motor 10 are almost linear, allowing for more linear and flexible control of the reed assembly 50 to achieve the weft-beating motion. This application directly connects the linear motor mover 13 to the reed assembly 50, eliminating intermediate transmission mechanisms and directly driving the reed in linear reciprocating motion. This reduces power loss and is more conducive to the control of the weft-beating motion by the loom 200 control system, thereby achieving efficient digital and electronic control of the loom 200 and significantly reducing system vibration and noise.

[0060] In this way, the weft insertion motion, which is traditionally strongly coupled with the main shaft 210, is decoupled, simplifying the structure and greatly reducing the complexity of system integration. This also reduces the load on the main shaft 210, which is beneficial for the high-speed operation of the loom 200. Furthermore, this setup eliminates the need to replace the direct-drive weft insertion mechanism 100 or adjust the main shaft 210; the parameters of the linear motor 10 can be directly adjusted to easily control the weft insertion stroke and force to adapt to different fabric types, making production more efficient and convenient. Therefore, the direct-drive weft insertion mechanism 100 proposed in this application can adapt to various air-jet and water-jet looms 200 with traditional asynchronous main shaft 210 transmission, direct-drive main shaft 210 transmission, and rapier looms 200, truly achieving wider product adaptability and compensating to some extent for start-up defects in the loom 200, greatly improving fabric quality.

[0061] In one embodiment, the drive module may further include a first connecting seat 30, which is used to connect the linear motor stator 11 and the frame of the loom 200. In this embodiment, the linear motor stator 11 is connected to the frame of the loom 200 through the first connecting seat 30 to ensure the stability of the drive module and improve the weft insertion accuracy.

[0062] In one embodiment, the first connecting seat 30 and the linear motor stator 11 are integrally formed. (Refer to...) Figure 4 In this embodiment, the linear motor stator 11 and the linear motor mover 13 are slidably coupled. The linear motor stator 11 extends or bends around its periphery to form a first connecting seat 30. The first connecting seat 30 is fixedly connected to the frame of the loom 200. By integrally molding the linear motor stator 11 and the first connecting seat 30, the integrity and stability of the drive module are improved, and it is also convenient to disassemble and assemble.

[0063] Of course, in other embodiments of this application, the linear motor stator 11 can be directly integrated onto the loom 200 frame. That is, the linear motor stator 11 is provided on the frame parts of the loom 200 during production. The form of the linear motor stator 11 depends on the actual needs. During the assembly of the loom 200, since the linear motor stator 11 is integrated on the loom 200 frame, it is only necessary to mate the linear motor mover 13 with the linear motor stator 11 for installation, without the need for the first connecting seat 30. This can further improve the integration and integrity of the loom 200, making the connection between the direct drive beat-up mechanism 100 and the loom 200 frame tighter and the operation more stable.

[0064] In one embodiment, the plane where the first connecting seat 30 is located is parallel to the center plane of the linear motor mover 13. That is, in this embodiment, the plane in which the direction of motion of the linear motor mover 13 is located is parallel to the plane where the first connecting seat 30 is located, so that when the first connecting seat 30 is horizontally set on the loom 200 frame, the linear motor mover 13 performs horizontal linear reciprocating motion, thereby driving the reed assembly 50 to perform horizontal linear reciprocating motion, and also making the force state of the drive module simpler and more stable during operation.

[0065] In one embodiment, the distance between the linear motor 10 and the reed assembly 50 can be less than a preset threshold. In this embodiment, the distance between the linear motor 10 and the reed assembly 50 can be the straight-line distance between the end of the linear motor mover 13 connected to the reed assembly 50 and the force-bearing point of the reed assembly 50, or it can be the straight-line distance between the geometric center point of the linear motor 10 and the geometric center point of the reed assembly 50. The specific distance can be determined according to the actual situation, and this embodiment does not limit it.

[0066] In this embodiment, the preset threshold can be a value greater than 0, such as 3 mm, 1 cm, 10 cm, 24 cm, 1 m, etc. In some embodiments, the preset threshold can be determined based on the straight-line distance between the power source and the force-bearing point of the reed assembly 50 in the beat-up mechanism of a traditional loom. The preset threshold can be much smaller than the straight-line distance between the power source and the force-bearing point of the reed assembly 50 in the beat-up mechanism of a traditional loom. It is understood that the preset threshold is used to characterize the high integration between the linear motor 10 and the reed assembly 50, and the specific value can be determined according to actual needs. This embodiment does not limit this.

[0067] Traditional looms 200 use a main shaft 210 to drive the beat-up mechanism, corresponding to the linear distance between the main shaft 210 and the force-bearing point of the reed assembly 50. However, traditional looms 200s often use linkages or other transmission structures to transmit power layer by layer between the power source and the reed assembly 50, resulting in significant power loss and complex motion. In this embodiment, the linear motor mover 13 is connected to the reed assembly 50, reducing the distance between them, simplifying the structure, making power transmission more direct, reducing power loss, and achieving higher integration and driving efficiency.

[0068] Specifically, in one embodiment, the linear motor mover 13 can be directly integrated into the reed assembly 50. In this embodiment, the reed assembly 50 and the linear motor stator 11 can be an integral structure. The linear motor mover 13 is already provided in the reed assembly 50 during production. When assembling the loom 200, it is only necessary to mate the linear motor mover 13 on the reed assembly 50 with the linear motor stator 11 for installation. This can further improve the integration and overall integrity of the loom 200, making the connection between the direct drive beat-up mechanism 100 and the loom 200 frame tighter and the operation more stable.

[0069] Optionally, the reed assembly 50 may include a reed mesh and a frame structure disposed around the reed mesh. The periphery of the frame is provided with plate-shaped, rod-shaped or other structures to serve as the linear motor mover 13 and to cooperate with the corresponding linear motor stator 11.

[0070] Taking the weft insertion direction as the horizontal direction as an example, the linear motor mover 13 can extend in the horizontal direction, and the linear motor stator 11 is located on one side of the reed assembly 50; or, the linear motor mover 13 can extend in the vertical direction, and the linear motor stator 11 is located above or below the reed assembly 50.

[0071] It is understood that in other embodiments, the magnetic component may be attached to the frame structure as the linear motor mover 13; or the linear motor mover 13 may be configured in other possible ways, which may be determined according to the actual situation, and this specification does not limit this.

[0072] In another embodiment, the direct drive weft insertion mechanism 100 may further include a second connecting seat 40, which is used to connect the reed assembly 50 and the linear motor mover 13; the first end of the linear motor mover 13 is connected to the second connecting seat 40, and the second end of the linear motor mover 13 is slidably engaged with the linear motor stator 11.

[0073] Reference Figures 3 to 5In this embodiment, a second connecting seat 40 can be provided between the linear motor mover 13 and the reed assembly 50. The second connecting seat 40 serves as a transition, allowing for better fixed connection between the linear motor mover 13 and the reed assembly 50 when they are separately installed, increasing the contact area with the reed assembly 50, and further improving stability and reliability. It should be noted that the second connecting seat 40 is relatively small. For example, considering overall strength, the thickness of the second connecting seat 40 can be 2 cm, and its height can be comparable to the width of the reed assembly. Here, the thickness refers to the distance between the surface of the second connecting seat 40 facing the reed assembly 50 and the surface facing the linear motor 10. Understandably, this thickness is used as a preset threshold. Since there is no intermediate transmission mechanism such as a connecting rod, this value is much smaller than the straight-line distance between the power source and the force-bearing point of the reed assembly 50 in the beat-up mechanism of a traditional loom. The method of connecting the linear motor mover 13 and the reed assembly 50 using the second connecting seat 40 has a higher degree of integration and less power transmission loss compared to the method of connecting the linear motor mover 13 and the reed assembly 50 using a linkage mechanism or other similar methods.

[0074] Understandably, in this embodiment, the linear motor mover 13 is integrated on the reed assembly 50. Theoretically, the straight-line distance between the end of the linear motor mover 13 connected to the reed assembly 50 and the force-bearing point of the reed assembly 50 is zero, resulting in low power transmission loss and high efficiency.

[0075] Reference Figure 3 and Figure 5 In one embodiment, the linear motor stator 11 is disposed on at least one side of the reed assembly 50, the linear motor mover 13 moves horizontally, and the second connecting seat 40 includes a transition part 41 and a fixing part 43. The transition part 41 is connected to the linear motor mover 13, and the fixing part 43 is connected to the reed assembly 50.

[0076] In some embodiments, the direct drive weft insertion mechanism 100 is provided with a linear motor 10. The linear motor stator 11 can be located on any side around the reed assembly 50 and serves as the main power source for driving the reed assembly 50. The adapter 41 is used to connect the linear motor mover 13, and the fixing part 43 is connected to the reed assembly 50 to increase the contact area and improve stability.

[0077] In some other embodiments, the direct-drive weft insertion mechanism 100 is provided with a plurality of linear motors 10, and a plurality of linear motor movers 13 are connected to the reed assembly 50 through at least one second connecting seat 40. The at least one second connecting seat 40 is provided with a plurality of fixing portions 43. At least some of the fixing portions 43 are provided on both sides of the adapter portion 41, and / or at least some of the fixing portions 43 are provided on the surface of the adapter portion 41 opposite to the linear motor movers 13.

[0078] In one embodiment, multiple linear motors 10 can be spaced apart along the length of the reed assembly 50, or they can be arranged symmetrically or asymmetrically above, below, and on the left and right sides of the reed assembly 50. The specific arrangement can be determined according to the actual situation, and this embodiment does not limit this.

[0079] Reference Figure 3 Optionally, the direct drive beat-up mechanism 100 may be equipped with two sets of linear motors 10, which are symmetrically arranged at both ends of the reed assembly 50, making the movement of the reed assembly 50 more stable and precise, and more conducive to the control of the beat-up movement and the high speed of the loom 200.

[0080] Of course, the configuration of the direct drive beat-up mechanism 100 is not limited to this. Depending on the actual loom 200, a single linear motor 10 or more linear motors 10 may be set, provided that the concept of this application is realized. No further limitations are made here.

[0081] Reference Figure 3 and Figure 4 In one embodiment, the reed assembly moves horizontally, the linear motor stator 11 can be arranged on both sides of the reed assembly 50 along the direction of movement, the linear motor mover 13 is arranged horizontally, and the second connecting seat 40 includes a connecting part 41 and a fixing part 43. The connecting part 41 is connected to the linear motor mover 13, and the fixing part 43 is arranged on opposite sides of the connecting part 41 and connected to the reed assembly 50.

[0082] In another embodiment, reference is made to Figure 5 The linear motor 10 is located above and / or below the reed assembly 50. The linear motor mover 13 moves horizontally. The second connecting seat 40 includes a connecting part 41 and a fixing part 43. The connecting part 41 is connected to the linear motor mover 13. The fixing part 43 is located on the surface of the connecting part 41 away from the linear motor mover 13. The fixing part 43 is connected to the reed assembly 50.

[0083] Optionally, when multiple linear motors 10 are provided, the adapter 41 can be integrated, with multiple fixing parts 43 provided on the adapter 41 and connected to the reed assembly 50, further improving the overall integrity and structural stability. Alternatively, multiple adapter parts 41 can be separately provided for each of the multiple linear motors 10, making disassembly and assembly convenient.

[0084] In this embodiment, the adapter 41 is a single plate or block arranged along the length of the reed assembly 50, and the fixing part 43 is arranged in an "L" shape, with one end connected to the adapter 41 and the other end connected to the reed assembly 50. Furthermore, to improve strength, the fixing part 43 may be formed with reinforcing ribs.

[0085] In this embodiment, a flat linear motor 10 is preferred.

[0086] Of course, in the horizontal and vertical push-type linear motor 10 structures shown in the above two embodiments, the thickness of the second connecting seat 40, the form and extension direction of the fixing part 43, the connection method, etc., can be adjusted according to the actual situation, and the embodiments in this specification do not limit this.

[0087] Furthermore, the arrangement of the linear motor 10 is not limited to the two embodiments described above, and can be combined and implemented within a reasonable range, without further limitation.

[0088] Understandably, in the two embodiments described above, the straight-line distance between the end of the linear motor mover 13 connected to the reed assembly 50 and the force-bearing point of the reed assembly 50 is the thickness of the second connecting seat 40. This thickness is also much smaller than the length of the connecting rod structure of a traditional loom. Therefore, relatively speaking, the solution in this embodiment also has higher efficiency and lower power loss.

[0089] Understandably, in one embodiment, the second connecting seat 40 is an integral structure, the adapter 41 has a threaded hole on the surface facing the linear motor 10, the linear motor mover 13 can be threadedly connected to the second connecting seat 40, and the fixing part 43 can be bolted to the reed assembly 50, which has a large contact area, making the connection between the reed assembly 50 and the linear motor mover 13 more stable and the overall structure more reliable.

[0090] In one embodiment, the linear motor 10 is a cylindrical linear motor 10, a flat linear motor 10, or a U-shaped linear motor 10.

[0091] The cylindrical linear motor 10 has been described in detail in the foregoing embodiments and will not be repeated here.

[0092] Specifically, for the flat linear motor 10, the linear motor stator 11 is provided with a linear channel 11a, and the linear motor mover 13 reciprocates relative to the linear motor stator 11 along the linear channel 11a. Optionally, the linear motor 10 is a single-sided flat type, that is, the linear motor stator 11 is located on one side of the linear motor mover 13; or, the linear motor 10 can be a double-sided flat type, with the linear motor stators 11 located on both sides of the linear motor mover 13 sandwiching to form the linear channel 11a.

[0093] Alternatively, the linear motor stator 11 can be arranged in a U-shape, with the two U-shaped clamps forming a linear channel 11a, in which the linear motor mover 13 reciprocates.

[0094] Of course, the linear motor 10 can also be implemented in other reasonable ways, which will not be listed here.

[0095] The present invention also proposes a loom 200. In one embodiment, the loom 200 may include a frame and a direct-drive beat-up mechanism 100. The specific structure of the direct-drive beat-up mechanism 100 is as described in the above embodiments, and the linear motor stator 11 in the direct-drive beat-up mechanism 100 is fixedly connected to the frame. Since the loom 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0096] The present invention further proposes a control system for a loom 200. The control system for the loom 200 is applied to the loom 200 described in the previous embodiment. The control system for the loom 200 may include an interaction module, a detection module, a main control module, and a drive control module. The interaction module is provided with a human-machine interface. The detection module is communicatively connected to the interaction module and is provided with a sensor. The sensor is located on the loom 200. The main control module is communicatively connected to the interaction module and the detection module. The drive control module is electrically connected to the drive module and is communicatively connected to the main control module and the detection module.

[0097] In one embodiment, the human-machine interface can be a touchscreen display screen, and the status parameters obtained by the detection module can be displayed on the display screen in real time so that the operator can understand the status information of the loom 200. Furthermore, the interaction module and the main control module can communicate via wired or wireless means. The main control module has preset models or control instructions, process parameters, etc., for controlling the operation of various mechanisms of the loom 200. Under the premise that the control system of the loom 200 is highly digitalized and electronic, the operator can input or change instructions or parameters through the interaction interface to adjust the process.

[0098] Optionally, operators can input the required weft insertion stroke parameters and weft insertion force parameters to the main control module through the interactive interface according to different process requirements. The main control module can then adjust and calculate accordingly and send control commands to the weft insertion mechanism control module, thereby conveniently realizing the control of the weft insertion movement.

[0099] The detection module is mainly used to monitor the operating status of the loom 200. Corresponding to the loom 200, the detection module includes a spindle 210 detection module, a direct drive weft insertion mechanism 100 detection module, a weft insertion mechanism 250 detection module, a warp feeding mechanism 230 detection module, and a winding mechanism 270 detection module.

[0100] Optionally, when the direct drive weft insertion mechanism 100 is driven by a linear motor 10, the detection module of the direct drive weft insertion mechanism 100 can be equipped with an encoder of the linear motor 10 connected to the linear motor 10 module, so as to compile the speed, displacement and other parameter signals of the weft insertion movement of the reed assembly 50 into communication signals and send them to the main control module to realize the status monitoring of the weft insertion movement.

[0101] Optionally, the sensors may also include speed sensors, displacement sensors, angle sensors, etc., located in other mechanisms of the loom 200.

[0102] Of course, the detection module is not limited to the form of sensors, but also includes devices such as detection circuits used to monitor electrical signals. Generally speaking, the detection module is mainly used for real-time monitoring of the operating status of the loom 200 system, including the motion status of the main shaft 210, such as the angle, speed, current, and voltage of the main shaft 210; the operating status of the direct-drive weft insertion mechanism 100, such as the displacement, speed, acceleration, voltage, and current of each direct-drive weft insertion mechanism 100; the operating status of the weft insertion mechanism 250, such as the water pressure, water volume, actuator voltage, and current of the water jet loom 200; and the warp feed / curling operation status, such as the warp feed / curling rate and yarn tension. This enables real-time monitoring of the overall status of the loom 200 and generates status parameters which are sent to the main control module for processing.

[0103] The main control module includes a main control chip for processing data parameters and issuing control commands. Control commands can be sent to the drive control module wirelessly or via wired connection. Various control commands are used for system timing-related control, fabric process control, and fabric forming quality control. In this embodiment, the drive control module includes a drive board equipped with control circuitry. Optionally, the drive control module includes a main shaft 210 control module, a weft insertion mechanism 250 control module, a warp feeding mechanism 230 control module, a crimping mechanism 270 control module, and a beat-up mechanism control module, corresponding to each mechanism of the loom 200.

[0104] The weft insertion mechanism control module is electrically connected to the drive module. This means the loom 200 control system no longer adjusts the movement of the weft insertion mechanism through the main shaft 210, but directly controls the movement of the reed assembly 50 through the drive module. This improves system efficiency and facilitates the control and adjustment of weft insertion force and stroke. Furthermore, by flexibly adjusting the weft insertion force and the distance between the weft insertion point and the reed assembly 50, it can theoretically adapt to all fabric types, eliminate fabric defects, and significantly improve fabric quality.

[0105] When the direct drive weft insertion mechanism 100 adopts a linear motor 10, a mathematical model can be established in the main control module to accurately control the direct drive weft insertion mechanism 100, realize force-displacement hybrid control and running curve planning control, thereby achieving linear control of weft insertion stroke and weft insertion force.

[0106] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
