[0002] In the garment manufacturing process, tubular fabrics, such as those for hems, need to be processed. When processing ribbed hems, stitches must be sewn parallel to the edges of the hems. Traditionally, this process relies on manual labor, which requires skilled operators to ensure quality and results in low production efficiency. Utility Model Content

[0003] Based on this, it is necessary to provide a tubular fabric sewing equipment to solve the problem that traditional ribbed shirt hem processing relies on manual labor and has low production efficiency.

[0005] The cloth driving device includes a first active rotating shaft and a second active rotating shaft that are arranged opposite to each other and spaced apart, wherein the first active rotating shaft and the second active rotating shaft are used to cooperate with each other to stretch the tubular cloth and drive the tubular cloth to rotate;

[0006] a supporting member, disposed between the first active rotating shaft and the second active rotating shaft, the supporting member being configured to be inserted into the expanded tubular fabric;

[0007] a sewing device, used for sewing the tubular fabric;

[0008] a cloth deviation detection device for detecting whether the tubular cloth deviates from a set position;

[0009] A correction device is arranged above the supporting member, and the correction device includes a swing mechanism and a cloth pressing passive rotating roller connected to the swing mechanism, the cloth pressing passive rotating roller is used to press on the tubular cloth on the supporting member, when the cloth deviation detection device detects that the tubular cloth deviates from the set position, the swing mechanism drives the cloth pressing passive rotating roller to swing to adjust the position of the tubular cloth until the tubular cloth is located at the set position.

[0010] In one embodiment, the first active rotation axis and the second active rotation axis are arranged in parallel.

[0011] In one embodiment, the distance between the first active rotation axis and the second active rotation axis is adjustable.

[0012] In one embodiment, the first active rotation axis and the second active rotation axis have the same height.

[0013] In one embodiment, the supporting member is a plate-shaped structure.

[0014] In one embodiment, the supporting member is arranged horizontally.

[0015] In one embodiment, the cloth deviation detection device includes a visual detection component, and the visual detection component is used to obtain an image of the tubular cloth.

[0016] In one embodiment, the distances between the cloth pressing passive rotating roller and the first active rotating shaft and the second active rotating shaft are the same.

[0017] In one embodiment, the correction device also includes a connecting assembly, which includes a connecting seat and a rotating shaft. The two ends of the cloth pressing passive rotating roller are respectively rotatably connected to the connecting seat, and the two ends of the rotating shaft are respectively connected to the swing mechanism and the connecting seat.

[0018] In one embodiment, the swing mechanism is a motor.

[0019] Compared with traditional technology, the above tubular fabric sewing equipment has the following advantages:

[0020] The aforementioned tubular fabric sewing equipment utilizes a first active rotating shaft and a second active rotating shaft to extend the tubular fabric. Rotation of the first and second active rotating shafts drives the tubular fabric to rotate. A sewing device sews the tubular fabric, creating stitches along the tubular fabric's edges as the tubular fabric rotates. Therefore, the aforementioned tubular fabric sewing equipment enables automated tubular fabric processing, reducing labor intensity and improving production efficiency.

[0021] If the tubular fabric deviates, the processed stitches will not be parallel to the edge of the tubular fabric, or even deviate from the tubular fabric. For this reason, the above-mentioned tubular fabric sewing equipment is also provided with a supporting member, a fabric deviation detection device and a deviation correction device to improve this problem. The fabric deviation detection device is used to detect whether the tubular fabric deviates from the set position. The cloth pressing passive rotating roller is pressed on the tubular fabric on the supporting member. When the tubular fabric rotates, it can drive the cloth pressing passive rotating roller to rotate around its roller axis. When the fabric deviation detection device detects that the tubular fabric deviates from the set position, the swing mechanism drives the cloth pressing passive rotating roller to swing to adjust the position of the tubular fabric until the tubular fabric is in the set position. In this way, it is ensured that the processed stitches are parallel to the edge of the tubular fabric, thereby improving production quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Please refer to Figure 1 and Figure 2 As shown, a tubular cloth sewing device 10 according to an embodiment includes a cloth driving device 100 , a supporting member 200 , a sewing device, a cloth deviation detecting device 400 , and a deviation correcting device 500 .

[0034] The cloth driving device 100 includes a first active rotating shaft 110 and a second active rotating shaft 120 that are opposite to and spaced apart from each other. The first active rotating shaft 110 and the second active rotating shaft 120 are used to cooperate with each other to stretch out the tubular cloth 20 and drive the tubular cloth 20 to rotate.

[0035] The supporting member 200 is disposed between the first active rotating shaft 110 and the second active rotating shaft 120. The supporting member 200 is used to be inserted into the expanded tubular fabric 20.

[0036] The sewing device is used to sew the tubular fabric 20 . Figure 1 FIG. 3 shows an exemplary position of the sewing needle 300 of the sewing device.

[0037] The cloth deviation detection device 400 is used to detect whether the tubular cloth 20 deviates from a set position.

[0038] The deviation-correcting device 500 is positioned above the support member 200. It includes a swing mechanism (not shown) and a passive cloth-pressing roller 510 connected to the swing mechanism. The passive cloth-pressing roller 510 is used to press against the tubular fabric 20 on the support member 200. When the fabric deviation detection device 400 detects that the tubular fabric 20 has deviated from its set position, the swing mechanism drives the passive cloth-pressing roller 510 to swing, adjusting the position of the tubular fabric 20 until it is in the set position.

[0039] The tubular fabric sewing device 10 utilizes the cooperation of the first and second active rotating shafts 110, 120 to stretch the tubular fabric 20. Rotation of the first and second active rotating shafts 110, 120 drives the tubular fabric 20 to rotate. A sewing device sews the tubular fabric 20, creating stitches along the edges of the tubular fabric 20 as the tubular fabric 20 rotates. Therefore, the tubular fabric sewing device 10 enables automated processing of the tubular fabric 20, reducing labor intensity and improving production efficiency.

[0040] The aforementioned tubular fabric sewing machine 10 is also equipped with a support member 200, a fabric deviation detection device 400, and a deviation correction device 500. The fabric deviation detection device 400 is used to detect whether the tubular fabric 20 has deviated from its set position. A cloth-pressing passive rotating roller 510 presses against the tubular fabric 20 on the support member 200. When the tubular fabric 20 rotates, it drives the cloth-pressing passive rotating roller 510 to rotate about its roller axis. When the fabric deviation detection device 400 detects that the tubular fabric 20 has deviated from its set position, a swing mechanism drives the cloth-pressing passive rotating roller 510 to swing to adjust the position of the tubular fabric 20 until it is in the set position. The swing direction of the cloth-pressing passive rotating roller 510 is opposite to the direction of deviation of the tubular fabric 20. The swing angle of the cloth-pressing passive rotating roller 510 matches the deviation angle of the tubular fabric 20, for example, 10°, to achieve deviation correction. Figure 3 This is a schematic diagram of the cloth pressing passive rotating roller swinging to one side. Figure 4 The schematic diagram of the passive rotating roller of the cloth pressing device swinging to the other side. In this way, the stitches processed are guaranteed to be parallel to the edge of the tubular cloth 20, thereby improving production quality.

[0041] The tubular fabric 20 may be, but is not limited to, a ribbed hem.

[0042] In one example, the first active rotating shaft 110 and the second active rotating shaft 120 are arranged in parallel. This allows for better rotation of the tubular fabric 20. Furthermore, in one example, when the tubular fabric 20 is in a set position, the cloth pressing passive rotating roller 510 is arranged parallel to the first active rotating shaft 110 and the second active rotating shaft 120.

[0043] In other examples, the first active rotating shaft 110 and the second active rotating shaft 120 may not be arranged in parallel to adapt to the shape of the tubular fabric 20 to be processed. For example, when the tubular fabric 20 is tapered, the first active rotating shaft 110 and the second active rotating shaft 120 may be arranged at an angle.

[0044] In one example, the distance between the first active rotating shaft 110 and the second active rotating shaft 120 is adjustable. Thus, by adjusting the distance between the first active rotating shaft 110 and the second active rotating shaft 120 , different sizes of the tubular fabric 20 can be accommodated.

[0045] In other examples, the distance between the first active rotation axis 110 and the second active rotation axis 120 may also be fixed.

[0046] In one example, the first active rotating shaft 110 and the second active rotating shaft 120 are at the same height, so that the tubular fabric 20 is in a horizontal state during processing, which is convenient for processing.

[0047] In other examples, the heights of the first active rotating shaft 110 and the second active rotating shaft 120 may also be different.

[0048] exist Figure 1 In the specific example shown, the supporting member 200 is a plate-shaped structure. Figure 1 In the specific example shown, the supporting member 200 is arranged horizontally.

[0049] In one example, there are at least two sewing devices, one for sewing two side edges of the tubular fabric 20 .

[0050] In one example, the cloth deviation detection device 400 includes a visual detection component 410, which is used to obtain an image of the tubular cloth 20. The visual detection component 410 is, for example, an industrial camera.

[0051] The cloth pressing passive rotating roller 510 is located between the first active rotating shaft 110 and the second active rotating shaft 120. In one example, the cloth pressing passive rotating roller 510 is equidistant from the first active rotating shaft 110 and the second active rotating shaft 120. This allows for better adjustment of the position of the tubular fabric 20.

[0052] In other examples, the distances between the cloth pressing passive rotating roller 510 and the first active rotating shaft 110 and the second active rotating shaft 120 may also be different.

[0053] In one example, the deviation-correcting device 500 further includes a connecting assembly 520 . The swing mechanism is connected to the cloth-pressing passive rotating roller 510 via the connecting assembly 520 .

[0054] In one example, the connecting assembly 520 includes a connecting seat 521 and a rotating shaft 522. Both ends of the cloth pressing passive rotating roller 510 are rotatably connected to the connecting seat 521. Both ends of the rotating shaft 522 are connected to the swing mechanism and the connecting seat 521 respectively.

[0055] In one example, the connecting base 521 includes a first connecting portion 5211, a second connecting portion 5212, and a third connecting portion 5213. The third connecting portion 5213 is a strip-shaped structure and is arranged parallel to the cloth-pressing passive rotating roller 510. The first connecting portion 5211 and the second connecting portion 5212 are respectively connected to the ends of the third connecting portion 5213. One end of the cloth-pressing passive rotating roller 510 is rotatably connected to the first connecting portion 5211. The other end of the cloth-pressing passive rotating roller 510 is rotatably connected to the second connecting portion 5212.

[0056] In one example, the rotating shaft 522 is connected to the middle position of the third connecting portion 5213 .

[0057] In one example, the oscillating mechanism is a motor.

[0058] It is understood that the operation of each component of the tubular fabric sewing apparatus 10 (including the fabric drive device 100, the support member 200, the sewing device, the fabric deviation detection device 400, and the deviation correction device 500) can be controlled by a controller commonly used in the art. The controller may be, for example, but not limited to, an industrial computer or a programmable logic controller (PLC).

[0059] The tubular fabric sewing device 10 utilizes the cooperation of the first and second active rotating shafts 110, 120 to stretch the tubular fabric 20. Rotation of the first and second active rotating shafts 110, 120 drives the tubular fabric 20 to rotate. A sewing device sews the tubular fabric 20, creating stitches along the edges of the tubular fabric 20 as the tubular fabric 20 rotates. Therefore, the tubular fabric sewing device 10 enables automated processing of the tubular fabric 20, reducing labor intensity and improving production efficiency.

[0060] The aforementioned tubular fabric sewing machine 10 is also equipped with a support member 200, a fabric deviation detection device 400, and a deviation correction device 500. The fabric deviation detection device 400 is used to detect whether the tubular fabric 20 has deviated from its set position. A passive cloth-pressing roller 510 presses against the tubular fabric 20 on the support member 200. As the tubular fabric 20 rotates, it drives the passive cloth-pressing roller 510 to rotate about its roller axis. When the fabric deviation detection device 400 detects that the tubular fabric 20 has deviated from its set position, an oscillating mechanism drives the passive cloth-pressing roller 510 to oscillate, adjusting the position of the tubular fabric 20 until it is in the set position. This ensures that the resulting stitches are parallel to the edge of the tubular fabric 20, improving production quality.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be based on the appended claims, and the specification may be used to interpret the content of the claims.
