Description

Technical Field

[0001] The present invention relates to the technical field of circular looms, and particularly to a support and fixing device and method for an image acquisition device used in a circular loom. Background Art

[0002] The weaving process of a circular loom is to interweave flat filaments vertically and horizontally to form cloth. There are many yarn spindles on the warp beam of the circular loom. According to the width of the woven cloth and the width of the flat filaments, a specified number of warp yarns within a specified range are used. Before the warp yarns enter the circular loom, the warp yarns are crossed and opened by the heddle frame of the warp yarns. During the automatic warp feeding process by the warp feeding mechanism, the weft yarns move in a circular motion through the crossed openings by the weft shuttles to weave into tubular cloth.

[0003] During the operation of the circular loom, it is necessary to observe the defects of the produced cloth, including situations such as wire drawing, uneven knitting, and oil stains. Due to the limitations of the circular loom structure, it is impossible to detect the defects of the woven cloth through the tube wall during the textile stage, and the woven cloth can only be detected during the cloth winding stage, and it is impossible to complete the full - range detection of all positions of the cloth. At the same time, during the high - speed textile process, it is impossible to collect images of the cloth in the textile process in real time, resulting in the problems that the machine cannot be repaired in time and the manufacturing cost of defective products is relatively high.

[0004] Therefore, it is necessary to provide a support and fixing device that can enable the image acquisition device to monitor the produced cloth in real time, facilitate the installation and disassembly of the image acquisition device, and effectively ensure the safety and stability of the operation of the circular loom to solve the above - mentioned technical problems. Summary of the Invention

[0005] To solve the above - mentioned technical problems, the present invention provides a support and fixing device for an image acquisition device used in a circular loom, which solves the technical problems in the prior art that the woven cloth is detected during the cloth winding stage, the full - range detection of all positions of the cloth cannot be completed, and during the high - speed textile process, it is impossible to collect images of the cloth in the textile process in real time, and the machine cannot be repaired in time.

[0006] The technical effects of the present invention are achieved as follows:

[0007] A support and fixing device for an image acquisition device used in a circular loom, comprising:

[0008] A C - shaped suspension member, which is detachably suspended on the support beam of the circular loom;

[0009] A longitudinal beam and a transverse beam, wherein one end of the longitudinal beam is fixedly connected to the transverse beam, and the other end is fixedly connected to the C-shaped suspension member, the longitudinal beam extending in a direction parallel to the main axis of the circular loom, the transverse beam is located in a horizontal direction, and the extending direction of the transverse beam is perpendicular to the main axis of the circular loom, and the end of the transverse beam away from the longitudinal beam is used for mounting a fixed image acquisition device;

[0010] A support column is fixedly connected between the longitudinal beam and the transverse beam, the axial direction of the support column being parallel to the main shaft of the circular loom, and the height of the support column matching the height of the needle holes of the circular loom. The image acquisition device is fixed between the main shaft and the knitting cylinder of the circular loom by a support and fixing device, enabling the image acquisition device to capture images of the cloth rotating around the main shaft in real time, allowing the machine to be repaired promptly based on cloth defects, effectively reducing the production cost of defective products. The image acquisition device is installed using the inherent support beam of the circular loom, making it easy to assemble and disassemble the image acquisition device, reducing assembly costs, and effectively improving the safety and stability of the circular loom's operation without changing the original structural design of the circular loom.

[0011] Furthermore, the support column is a cylindrical structure so that the air blown out of the air blow pipe of the circular loom can bypass the support column and blow to the corresponding needle hole. By arranging the cylindrical support column at the needle hole position, the air blown out of the air blow hole of the air blowing device rotating around the main shaft can bypass the support column and blow to the corresponding needle hole of the circular loom, effectively ensuring the needle hole cleaning effect.

[0012] Furthermore, a screw hole is provided on the lower end surface of the C-shaped hanging member, and the C-shaped hanging member is installed and fixed on the support beam by passing a bolt through the screw hole.

[0013] Furthermore, a vertically downward hanging portion is fixedly provided on the side end of the lower end surface of the C-shaped hanging member, and the hanging portion is fixedly connected to the longitudinal beam.

[0014] Furthermore, it also includes a camera fixing bracket, which is fixedly connected to the bottom of the end of the crossbeam away from the longitudinal beam. The extension direction of the camera fixing bracket is parallel to the main axis of the circular loom and perpendicular to the shooting direction of the camera of the image acquisition device.

[0015] Furthermore, it also includes a light source fixing bracket, which is arranged on the side of the camera fixing bracket away from the main shaft of the circular loom, and the irradiation direction of the light source of the image acquisition device fixedly connected to the light source fixing bracket is in the same direction as the shooting direction of the camera.

[0016] Furthermore, the light source fixing bracket is movable along the extension direction of the beam to adjust the distance between the light source and the camera.

[0017] In addition, a support and fixation method for an image acquisition device for a circular loom is provided. The method is implemented based on the above-mentioned support and fixation device for the image acquisition device for a circular loom, and includes:

[0018] Suspend the C-shaped suspension member on the support beam of the circular loom, and lock and fix the C-shaped suspension member with bolts;

[0019] Fix the longitudinal beam in a vertical state on the suspension part below the C-shaped suspension member, and make the longitudinal beam parallel to the main shaft of the circular loom;

[0020] Fix the cross beam and the longitudinal beam in a connected manner, and make the extending direction of the cross beam align with the main shaft of the circular loom;

[0021] Fix the camera fixing bracket with a camera installed thereon on the cross beam;

[0022] After fixing the light source fixing bracket with a light source installed thereon on the cross beam, adjust the distance between the light source fixing bracket and the camera fixing bracket according to a preset distance, and then fix it at the corresponding position on the cross beam, and make the camera shooting direction and the light source irradiation direction both pass through the main shaft of the circular loom.

[0023] Further, fixing the cross beam and the longitudinal beam in a connected manner, and making the extending direction of the cross beam align with the main shaft of the circular loom includes:

[0024] Fix one end of the support column on the longitudinal beam and keep the support column in a vertical state, so that the gas blown out by the blow pipe located at the center position of the circular loom can bypass the support column and blow towards the corresponding pinhole position;

[0025] Fix the cross beam and the other end of the support column in a connected manner, and make the extending direction of the fixed cross beam align with the main shaft of the circular loom.

[0026] Further, before fixing the camera fixing bracket with a camera installed thereon on the cross beam, it includes:

[0027] Align the extending direction of the camera fixing bracket with the center position of the camera and keep it perpendicular to the camera shooting direction to complete the fixed connection with the camera;

[0028] Align the extending direction of the light source fixing bracket with the center position of the light source and keep it perpendicular to the light source irradiation direction to complete the fixed connection with the light source.

[0029] As described above, the present invention has the following beneficial effects:

[0030] 1) Fix the image acquisition device between the main shaft and the knitting cylinder of the circular loom through the support and fixing device, so that the image acquisition device can collect the cloth images rotating around the main shaft in real time, repair the machine in a timely manner for cloth defects, and effectively reduce the production cost of defective products.

[0031] 2) Utilize the inherent support beam of the circular loom to complete the installation of the image acquisition device, realizing the easy assembly and disassembly of the image acquisition device, reducing the assembly cost. At the same time, without changing the original structural design of the circular loom, the safety and stability of the circular loom operation are effectively improved.

[0032] 3) By setting a support column with a cylindrical structure at the position of the needle hole, the air flow blown out from the air holes of the blowing device rotating around the main shaft can bypass the support column and blow to the corresponding needle holes of the circular loom, effectively ensuring the cleaning effect of the needle holes.

[0045] Embodiment 1:

[0046] As Figures 1-5 shown, the embodiment of this specification provides a support and fixing device for an image acquisition device used in a circular loom, which is used to fix the image acquisition device on the circular loom so that the image acquisition device can perform real-time detection on the cloth produced during the weaving process of the circular loom, including:

[0047] A C-shaped suspension member 1, which is detachably suspended on the support beam 2 of the circular loom;

[0048] A longitudinal beam 3 and a cross beam 4, one end of the longitudinal beam 3 is used for fixedly connecting with the cross beam 4, and the other end is fixedly connected with the C-shaped suspension member 1. The extending direction of the longitudinal beam 3 is parallel to the main shaft 5 of the circular loom. The cross beam 4 is in the horizontal direction, and the extending direction of the cross beam 4 is perpendicular to the main shaft 5 of the circular loom. The end of the cross beam 4 far from the longitudinal beam 3 is used for installing and fixing the image acquisition device;

[0049] A support column 6, which is fixedly connected between the longitudinal beam 3 and the cross beam 4. The axial direction of the support column 6 is parallel to the main shaft 5 of the circular loom, and the height where the support column 6 is located matches the height of the pinhole of the circular loom. Among them, the image acquisition device includes a camera and a light source.

[0050] In this embodiment, the original structure of the circular loom is provided with a plurality of support beams 2 for fixing yarns, which are located in the horizontal direction. The positions of the support beams 2 are fixedly arranged above the main shaft 5. The plurality of support beams 2 are symmetrically distributed with the extending direction of the main shaft 5 as the axis, and the intersection points of the axes of all the support beams 2 are located on the axis of the main shaft 5.

[0051] The weaving principle of the circular loom is as follows: during the weaving process, the cloth rotates along the main shaft 5, and the woven cloth is collected in the collection bag below the circular loom from top to bottom. The image acquisition device needs to irradiate the cloth radially outward corresponding to the main shaft to perform image acquisition to ensure that all positions of the cloth pass through the acquisition area of the image acquisition device.

[0052] It should be noted that in the traditional structure of the circular loom, there is a fixed support column 14 between the main shaft 5 and the air chamber 17. The line of the fixed support column 14 and the axis of the main shaft 5 are on the same straight line, and the transmission rod is arranged parallel to the fixed support column 14.

[0053] The main shaft 5 is in transmission connection with the air chamber 17 through the transmission rod, so that during the rotation of the main shaft 5, the air chamber 17 and the air blowing pipe 7 on the air chamber 17 can be driven to rotate synchronously with the main shaft 5 through the transmission rod for cleaning the needles of the circular loom.

[0054] One bearing 18 is provided at each of the top and bottom ends of the air chamber 17. The support shaft 20 passing through the inside of the air chamber 17 is installed between the two bearings 18 of the air chamber 17. One end of the support rod 19 passes through the bearing 18 at the top end of the air chamber 17 and is connected to the bottom of the support rod 19 above the air chamber 17 by screws. The top of the support rod 19 is fixedly connected to the central position where the plurality of support beams 2 intersect and are connected through a nut 16. The axis of the support rod 19 and the axis of the main shaft 5 are on the same straight line.

[0055] The other end of the support rod 19 passes through the bearing 18 at the bottom end of the air chamber 17 and is connected to the fixed support column 14 by screws.

[0056] The two bearings 18 provided on the air chamber 17 are used to ensure that when the air chamber 17 and the air blowing pipe 7 rotate, the support rod 19 above the air chamber 17 and the fixed support column 14 below do not rotate with the air chamber 17 and remain stationary.

[0057] In order to complete the detection of the cloth during the weaving process, the image acquisition device needs to be fixed inside the cylindrical cloth, and the shooting direction of its camera is located in the radial direction corresponding to the axis of the main shaft 5. Therefore, in the prior art, the image acquisition device is fixed on the fixed support column 14 by setting a fixing frame 15 in the radial direction of the fixed support column 14, so that the image acquisition device is fixed relative to the rotating cloth and does not move, and the cloth image in the shooting area is collected in real time during the rotation of the cloth to complete the cloth detection process.

[0058] However, since the drive rod of the circular loom rotates around the main shaft 5, it will interfere with the fixed frame 15 and the image acquisition device. Therefore, with this fixing method, it is necessary to change the drive mode of the drive rod of the traditional circular loom, that is, to add gear drive, so that the drive rod becomes the auxiliary shaft 10 (only rotates by itself, does not rotate around the main shaft 5), as Figure 6 and Figure 7 shown.

[0059] The circular loom obtained after the change includes a main shaft 5, an auxiliary shaft 10, an upper drive gear 11, a lower drive gear 12 and components such as bearings located on the base. The bearings drive the main shaft 5 to rotate around its axis through the lower drive gear 12, the auxiliary shaft 10 and the upper drive gear 11 to realize the operation of the circular loom.

[0060] However, the shape of the lower part of the cloth near the winding bracket of the winding mechanism is rectangular, so that the cloth corresponding to the image acquisition area in the radial direction of the circular loom cannot maintain a regular arc state, and the acquired image is inaccurate or unclear, resulting in inaccurate cloth detection. Therefore, in order to make the cloth in the image acquisition area maintain a regular shape, it is necessary to set up a cloth support ring 13 in a certain area corresponding to the height where the image acquisition device is located. Since the image acquisition device is fixed on the fixed support column 14, therefore, the cloth support ring 13 needs to be fixed on the fixed support column 14 as well.

[0061] The cloth support ring 13 fixed on the fixed support column 14 will be subject to the rotational friction force of the cloth, and will continuously apply a rotational torque to the support shaft 20 and the support rod 19 through the fixed support column 14, resulting in the loosening of the nut 16 for fixing the support rod 19 at the central position where the support beams 2 intersect and connect, so that the fixed support shaft 20 and the support rod 19 are driven by the cloth support ring 13 to rotate, affecting the operation safety and stability of the circular loom. At the same time, the cost of changing the transmission structure is relatively high, and the installation and removal processes of the image acquisition device and the cloth support ring 13 are complex.

[0062] Therefore, in order to fix the image acquisition device inside the circular loom and effectively acquire the images of the cloth rotating along the extension direction of the main shaft, and at the same time effectively improve the safety and stability performance of the circular loom operation, the present application designs a support fixing device, which adopts a connection method from top to bottom and from outside to inside, and fixes the image acquisition device between the main shaft and the knitting cylinder of the circular loom through the support fixing device with a segmented fixing structure, so that the image acquisition device can take pictures of the cloth from inside to outside, effectively ensuring the image acquisition effect to realize the all-round detection of each position of the cloth.

[0063] Moreover, without changing the existing structure of the circular loom, the structure of the support and fixing device is ensured to be simple and easy to assemble. The segmented fixing structure facilitates the processing of local parts, reduces the manufacturing cost and the installation and disassembly time. It has strong versatility and can be widely applied to different types of circular looms.

[0064] Specifically, the function of the longitudinal beam 3 is to extend the installation position downward. At the same time, a cross beam 4 is provided, which can extend the fixing positions of the camera and the light source in the direction towards the central area of the circular loom, aiming to ensure an effective distance between the camera, the light source and the cloth. While ensuring that the shooting area is large enough, it can also ensure the quality of the collected cloth images, avoiding the phenomenon that the image acquisition device is too close to the cloth and unable to collect the overall information of the cloth, resulting in missed image acquisition.

[0065] Preferably, the support column 6 is of a cylindrical structure so that the gas blown out by the air blowing pipe 7 of the circular loom can bypass the support column 6 and blow towards the corresponding needle holes to blow off the dust at the needle hole positions.

[0066] The installation position of the cross beam 4 is used to enable the image acquisition device to collect an image area that at least covers the current cloth weaving position corresponding to the needles of the circular loom. Therefore, in the support and fixing device that uses the support column 6 to complete the fixed connection between the cross beam 4 and the longitudinal beam 3, after being installed and fixed on the support beam 2 of the circular loom, the support column 6 is located between the needle holes of the needles and the air blowing device, affecting the air flow blown out by the air blowing device to reach the corresponding needle holes.

[0067] Therefore, by providing a support column 6 with a cylindrical structure at the needle hole position, the air flow blown out from the air blowing holes of the air blowing device rotating around the main shaft 5 can bypass the support column 6 and blow to the corresponding needle holes of the circular loom, effectively ensuring the cleaning effect of the needle holes.

[0068] Preferably, the lower end surface of the C-shaped suspension member 1 is provided with a threaded hole, and the C-shaped suspension member 1 is installed and fixed on the support beam 2 by a bolt passing through the threaded hole.

[0069] Specifically, the C-shaped suspension member is a component that directly contacts the circular loom. The opening position of the C-shaped suspension member is located on its side, and the C-shaped suspension member can be directly hung on the support of the circular loom from the opening position, which is convenient for disassembly and assembly.

[0070] In this embodiment, the bolt used for the C-shaped suspension member 1 is a manual locking bolt, aiming to be able to manually fix the hung bracket fixing device without the need to use tools for locking.

[0071] Preferably, a vertically downward hanging portion 101 is fixedly provided at the side end of the lower end surface of the C-shaped suspension member 1, so as to facilitate the longitudinal beam 3 to complete the fixed connection with the C-shaped suspension member 1 in the vertical direction through the hanging portion 101.

[0072] Preferably, it further includes a camera fixing bracket 8. The camera fixing bracket 8 is fixedly connected to the lower part of one end of the cross beam 4 away from the longitudinal beam 3. The extending direction of the camera fixing bracket 8 is parallel to the main shaft 5 of the circular loom and perpendicular to the shooting direction of the image acquisition device.

[0073] Preferably, it further includes a light source fixing bracket 9. The light source fixing bracket 9 is arranged on one side of the camera fixing bracket 8 away from the main shaft 5 of the circular loom. The irradiation direction of the light source of the image acquisition device fixedly connected to the light source fixing bracket 9 and the shooting direction of the camera are in the same direction.

[0074] Preferably, the light source fixing bracket 9 is movable along the extending direction of the cross beam 4 to adjust the distance between the light source and the camera.

[0075] In this embodiment, the light source fixing bracket 9 is fixed in the slot of the cross beam 4 by bolts. The slot has a certain length in the extending direction of the cross beam 4, so that by changing the fixing position of the light source fixing bracket 9 on the cross beam 4, the distance between the light source and the camera can be adjusted to ensure a proper relative position between the light source and the camera.

[0076] The embodiment of this specification provides a support and fixing method for an image acquisition device used in a circular loom. The method is implemented based on the support and fixing device for the image acquisition device used in the circular loom in Embodiment 1, and includes:

[0077] Suspending the C-shaped hanging member 1 on the support beam 2 of the circular loom and locking and fixing the C-shaped hanging member 1 by bolts;

[0082] In a specific implementation manner, fixing the cross beam 4 to the longitudinal beam 3 and making the extending direction of the cross beam 4 align with the main shaft 5 of the circular loom includes:

[0083] Fix one end of the support column 6 on the longitudinal beam 3 and keep the support column 6 in a vertical state, so that the gas blown out by the blow pipe 7 at the central position of the circular loom can bypass the support column 6 and blow towards the corresponding pinhole position;

[0084] Fix the cross beam 4 to the other end of the support column 6, and align the extending direction of the fixed cross beam 4 with the main shaft 5 of the circular loom.

[0085] In a specific embodiment, fix the camera fixing bracket 8 equipped with a camera on the cross beam 4, which includes:

[0086] Align the extending direction of the camera fixing bracket 8 with the center position of the camera and keep it perpendicular to the camera shooting direction to complete the fixed connection with the camera;

[0087] Align the extending direction of the light source fixing bracket 9 with the center position of the light source and keep it perpendicular to the light source irradiation direction to complete the fixed connection with the light source.

[0090] Without conflict, the above embodiments and the features in the embodiments in this article can be combined with each other.
