Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting machines, in particular to a cloth rolling machine and a circular knitting machine with online cloth inspection capabilities. Background Art

[0002] Fabric surface inspection is an important part of fabric quality control. Traditional fabric inspection uses manual inspection, which is not only time-consuming and labor-intensive, but also has high rates of missed detection and false detection. In recent years, with the rapid development of industrial automation and digital image processing technology, automated inspection through automated image processing has gradually replaced traditional manual inspection. For example, the Chinese patented fabric inspection machine with application publication number CN113495077A realizes automated inspection through camera elements. However, the existing fabric inspection machine is an independent device that unrolls the rolled fabric for inspection and then rewinds it. This inspection requires the addition of an independent inspection process and also requires steps such as fabric roll handling, which is less efficient. In order to improve inspection efficiency, how to achieve online inspection is the problem to be solved in this case. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a cloth rolling machine and a circular knitting machine with online cloth inspection.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: A cloth rolling machine with online cloth inspection comprises: a sliding assembly, a backlight assembly, a camera assembly, and a driving mechanism;

[0005] The sliding assembly includes a track, a movable vehicle, and a transmission belt assembly. The movable vehicle is movably arranged on the track. The transmission belt assembly is arranged on one side of the track. The transmission belt assembly is connected to the movable vehicle and is used to drive the movable vehicle to move along the length of the track. The sliding assembly is provided with two groups. The tracks of the two groups of sliding assemblies are arranged in parallel and spaced apart. There is a gap between the two groups of tracks to accommodate the passage of fabric.

[0006] The backlight assembly and the camera assembly are respectively installed on the movable vehicles of the two sets of sliding assemblies, and the backlight assembly and the camera assembly are arranged opposite to each other, and the fabric passes through the space between the backlight assembly and the camera assembly;

[0007] The driving mechanism includes a motor and a synchronous shaft. The synchronous shaft connects the two sets of transmission belt assemblies. The motor drives the two sets of transmission belt assemblies to move synchronously through the synchronous shaft.

[0008] Furthermore, the backlight assembly includes a flat-panel light-distributing lamp, and the camera assembly includes a light shield and a camera. The light shield forms a cylindrical shield surrounding all sides, and an opening is provided at one end of the light shield facing the flat-panel light-distributing lamp. The camera is provided at the other end of the light shield and faces the direction of the opening.

[0009] Furthermore, it also includes guide rollers, which are provided in two groups. The two groups of guide rollers are respectively provided on both sides of the sliding component. The portion of the cloth passing through the two groups of guide rollers is conveyed at an angle parallel to the flat plate even light lamp.

[0010] Furthermore, the camera assembly also includes a fill light, which is arranged next to the camera and irradiates toward the opening of the light shield.

[0011] Furthermore, the track is a square rail with a rectangular cross-section, and the movable vehicle includes a support block and a plurality of roller assemblies. The roller assemblies are mounted on the support block, and the roller assemblies are distributed on four sides of the track to form a clamping positioning.

[0012] Furthermore, the roller assembly includes an eccentric roller assembly, which includes a first shaft segment, a second shaft segment, and a bearing. The axes of the first shaft segment and the second shaft segment are parallel and offset. The first shaft segment is installed on the support block, and the bearing is installed on the second shaft segment. The bearing position is adjusted by rotating the axis angle of the first shaft segment and positioning it.

[0013] Furthermore, the roller assembly also includes a centered roller assembly. The centered roller assembly is arranged on one side of the two opposite sides of the track, and the eccentric roller assembly is arranged on the other side. The centered roller assembly and the eccentric roller assembly form a clamp for the track.

[0014] Furthermore, the driving mechanism further includes an encoder, which is connected to the synchronization shaft and obtains the rotation data of the synchronization shaft through the encoder.

[0015] Furthermore, it also includes a host, which is connected to the encoder, motor, backlight assembly, and camera assembly.

[0016] A circular knitting machine comprises the above-mentioned cloth winding machine with online cloth inspection function.

[0017] From the above description of the present invention, it can be seen that compared with the prior art, the cloth rolling machine and circular knitting machine with online cloth inspection provided by the present invention have the following advantages:

[0018] 1. This application realizes online detection of fabric by setting a camera inside the fabric winding machine to shoot the fabric. The relatively independent fabric inspection equipment does not require fabric handling and repeated unwinding and rewinding steps, which greatly improves production efficiency.

[0019] 2. This application adopts a design in which the backlight assembly and the camera assembly are opposite to each other, and a motor is used to synchronously drive the two groups of movable vehicles to move synchronously. Therefore, during the movement, the relative position of the backlight assembly and the camera assembly does not change, ensuring the uniformity of the light source during the shooting process, and thus ensuring the accuracy of the detection.

[0020] 3. The light shield forms a ring-shaped shield to block the influence of external side light. At the same time, the flat-panel even-lighting lamp forms a uniform luminous surface. Therefore, the fabric image captured by the camera is backlit by the flat-panel even-lighting lamp with uniform light, and the image consistency is good, which further ensures the detection accuracy.

[0021] 4. Set up the encoder to record the location information of the captured image and provide positioning data for subsequent defect location elimination. BRIEF DESCRIPTION OF THE DRAWINGS

The roller assembly 122 is installed on the support block 121, and each roller assembly 122 is distributed on the four sides of the track 11 to form a clamping positioning. The roller assembly 122 includes an eccentric roller assembly 1221 and a centered roller assembly 1222. The eccentric roller assembly 1221 includes a first shaft segment 12211, a second shaft segment 12212, and a bearing 12213. The axes of the first and second shaft segments 12211 and 12212 are parallel and offset. The first shaft segment 12211 is mounted on the support block 121, and the bearing 12213 is mounted on the second shaft segment 12212. The position of the bearing 12213 can be adjusted by rotating the axis angle of the first shaft segment 12211 and positioning it. The centered roller assembly 1222 is installed on one side of the opposite sides of the track 11, and the eccentric roller assembly 1221 is installed on the other side. The centered roller assembly 1222 and the eccentric roller assembly 1221 form a clamping force on the track 11.

[0032] The backlight assembly 2 and camera assembly 3 are mounted on the movable carriages 12 of the two sets of sliding assemblies 1, respectively. The backlight assembly 2 and camera assembly 3 are positioned opposite each other, and the fabric passes between them. The backlight assembly 2 includes a flat-panel light-distributing lamp 21, and the camera assembly 3 includes a light shield 31, a camera 32, and a fill light 33. The light shield 31 forms a cylindrical shield that surrounds the entire periphery. The end of the light shield 31 facing the flat-panel light-distributing lamp 21 has an opening 311. The camera 32 is located at the other end of the light shield 31 and faces the opening 311. The fill light 33 is located next to the camera 32 and shines light toward the opening 311 of the light shield 31. Two sets of guide rollers 5 are provided, one on each side of the sliding assembly 1. The portion of the fabric passing through the two sets of guide rollers 5 is conveyed at an angle parallel to the flat-panel light-distributing lamp 21.

[0033] The driving mechanism 4 includes a motor 41, a synchronous shaft 42, and an encoder 43. The synchronous shaft 42 connects the two sets of transmission belt assemblies 13. The motor 41 is preferably a servo motor. The motor 41 drives the two sets of transmission belt assemblies 13 to move synchronously through the synchronous shaft 42. The encoder 43 is connected to the synchronous shaft 42, and the rotation data of the synchronous shaft 42 is obtained through the encoder 43.

[0037] The fabric woven by the circular knitting machine is transported through the guide roller 5 and passes between the two sets of tracks 11. The motor 41 of the drive mechanism 4 drives the two sets of transmission belt assemblies 13 to move back and forth through the synchronous shaft 42, thereby driving the backlight assembly 2 and the camera assembly 3 to move back and forth along the width direction of the fabric. The camera assembly 3 takes pictures of the fabric during the movement and sends the captured images to the host for processing to realize online fabric detection. The reciprocating movement of the camera assembly 3, combined with the conveying action of the fabric itself, can realize comprehensive detection of fabric production.

[0038] A motor 41 is used to synchronously drive the two sets of movable vehicles 12. Therefore, during the movement, the relative position of the backlight assembly 2 and the camera assembly 3 does not change, ensuring the uniformity of the light source during the shooting process, thereby ensuring the accuracy of detection. The light shield 31 of the camera assembly 3 forms an annular shield to block the influence of external side light. At the same time, the flat-panel light-distributing lamp 21 forms a uniform luminous surface. Therefore, the fabric image captured by the camera 32 is backlit by the uniform flat-panel light-distributing lamp 21, and the image consistency is good, further ensuring the accuracy of detection. An encoder 43 is provided to record the position information of the captured image, providing positioning data for subsequent defect location elimination.
