[0001] This application relates to the field of fabric laying technology, and in particular to an edge-aligning method; it also relates to an edge-aligning device, system and computer-readable storage medium. Background Technology

[0002] A fabric spreading machine is a device that lays rolls of seamless fabric layer by layer onto a cutting table for cutting. To prevent fabric misalignment, the fabric is aligned and corrected during the spreading process. An alignment device is used to perform this alignment and correction. Current alignment devices utilize photoelectric sensors to identify the presence of fabric at the current position and determine the fabric edge position based on the signal output by the photoelectric sensors, then control an alignment motor to align the left and right edges. However, with the development of the garment industry, composite fabrics have emerged that require alignment of the inner fabric edges, but existing alignment devices can only align the outer fabric edges, not the inner ones. Therefore, providing an alignment solution that can align the inner fabric edges has become a technical problem urgently needing to be solved by those skilled in the art. Summary of the Invention

[0003] The purpose of this application is to provide an edge-aligning method that can align internal edges. Another purpose of this application is to provide an edge-aligning device, system, and computer-readable storage medium, all of which have the above-mentioned technical effects.

[0006] Analyze the image of the target area to identify the inner fabric.

[0007] Based on the recognition result, a first detection signal is output so that the opposite side circuit can control the opposite side motor to rotate forward or reverse according to the first detection signal.

[0009] Determine the R component, G component, and B component of the image;

[0010] Determine whether the R component, the G component, and the B component are within the corresponding threshold ranges;

[0011] If the R component, the G component, and the B component are all within their respective threshold ranges, then the inner edge fabric is identified.

[0012] Optionally, the step of outputting the first detection signal based on the recognition result includes:

[0013] Based on the recognition result, the first detection signal is output to the opposite edge switching circuit, so that the first detection signal is output to the opposite edge circuit through the opposite edge switching circuit; the opposite edge switching circuit is used to output the first detection signal or the second detection signal output by the photoelectric sensor to the opposite edge circuit; the photoelectric sensor is used to detect the position of the fabric or to detect whether there is fabric.

[0014] Optionally, the step of outputting the first detection signal based on the recognition result includes:

[0015] If the inner fabric is detected, the first detection signal output will be high.

[0016] If the inner fabric is not detected, the first detection signal output will be low.

[0017] Optional, also includes:

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0034] Figure 3 This is a schematic diagram of an opposite-side switching circuit provided in an embodiment of this application. Detailed Implementation

[0035] The core of this application is to provide an edge-aligning method that can align internal edges. Another core aspect of this application is to provide an edge-aligning device, system, and computer-readable storage medium, all of which have the aforementioned technical effects.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please refer to Figure 1 , Figure 1This is a flowchart illustrating an edge-matching method provided in an embodiment of this application. (Refer to...) Figure 1 As shown, the method includes:

[0038] S101: Acquire an image of the target area on the fabric spreading machine;

[0039] S102: Analyze the image of the target area and identify the inner edge fabric;

[0040] S103: Based on the recognition result, output the first detection signal so that the opposite side circuit can control the opposite side motor to rotate forward or reverse according to the first detection signal.

[0041] This embodiment acquires images of the target area on the fabric spreading machine, analyzes the images, and identifies the inner edge fabric. The aligning device outputs different first detection signals depending on whether it detects or does not detect the inner edge fabric. This allows the aligning circuit to control the aligning motor to rotate forward or backward, thereby moving the main unit to achieve aligning. The target area is the area captured by the aligning device, and the presence or absence of detected inner edge fabric in this area reflects the position of the inner edge. The aligning device can be a miniature camera. The miniature camera captures images by illuminating from the outside in. To enable the miniature camera to focus on a single point and capture images of solid-color fabric, it can be mounted close to the fabric.

[0042] In some embodiments, analyzing the image to identify the inner fabric includes:

[0043] Determine the R component, G component, and B component of the image;

[0044] Determine whether the R component, the G component, and the B component are within the corresponding threshold ranges;

[0045] If the R component, the G component, and the B component are all within their respective threshold ranges, then the fabric is an inner edge fabric.

[0046] Specifically, after imaging the edge device, a three-primary-color space represented by the RGB primary colors is obtained. After numerical conversion, the colors of the image are expressed in the three dimensions of R, G, and B, that is, the R component, G component, and B component are determined, with a range of 0~255. It is then determined whether each of the R, G, and B components is within its corresponding threshold range. If all three are within their respective threshold ranges, the fabric is considered inner edge fabric. If none of the three are within their respective threshold ranges, the fabric is not inner edge fabric.

[0047] In some embodiments, the step of outputting the first detection signal based on the recognition result includes:

[0048] If the inner fabric is detected, the first detection signal output will be high.

[0049] If the inner fabric is not detected, the first detection signal output will be low.

[0050] In addition, in some embodiments, outputting the first detection signal based on the recognition result includes:

[0051] Based on the recognition result, the first detection signal is output to the opposite edge switching circuit, so that the first detection signal is output to the opposite edge circuit through the opposite edge switching circuit; the opposite edge switching circuit is used to output the first detection signal or the second detection signal output by the photoelectric sensor to the opposite edge circuit; the photoelectric sensor is used to detect the position of the fabric or to detect whether there is fabric.

[0052] In this embodiment, the first detection signal output by the edge-aligning device is not directly output to the edge-aligning circuit, but rather to the edge-aligning switching circuit. The edge-aligning switching circuit also receives the second detection signal output by the photoelectric sensor. When performing inner edge alignment, the edge-aligning switching circuit outputs the first detection signal to the edge-aligning circuit. When performing ordinary edge alignment, the edge-aligning switching circuit outputs the second detection signal to the edge-aligning circuit, thus achieving compatibility between ordinary edge alignment based on photoelectric sensors and inner edge alignment based on miniature cameras.

[0053] The photoelectric sensor may include a first photoelectric sensor, a second photoelectric sensor, and a third photoelectric sensor. The first and second photoelectric sensors are used to detect the position of the fabric edge, while the third photoelectric sensor is used to detect whether there is fabric on the spreading machine. If the first photoelectric sensor detects fabric at its installation position, it outputs a high level; otherwise, it outputs a low level. If the second photoelectric sensor detects fabric at its installation position, it outputs a high level; otherwise, it outputs a low level. If the third photoelectric sensor detects fabric at its installation position, it outputs a high level; otherwise, it outputs a low level.

[0054] The function of the switching circuit is to selectively output the first detection signal and the second detection signal. It may include: a relay; the relay includes a first normally open contact, a second normally open contact, a first normally closed contact, and a second normally closed contact; the output terminal of the miniature camera can be connected to the first normally open contact and the second normally open contact respectively, the output terminal of the first photoelectric sensor can be connected to the first normally closed contact, and the output terminal of the second photoelectric sensor can be connected to the second normally closed contact.

[0055] When the relay coil is energized, the first normally open contact and the second normally open contact close, and the first normally closed contact and the second normally closed contact open, and the first detection signal output by the miniature camera is output to the opposite circuit; when the relay coil is de-energized, the first normally open contact and the second normally open contact open, and the first normally closed contact and the second normally closed contact close, and the second detection signal output by the first photoelectric sensor and the second photoelectric sensor is output to the opposite circuit.

[0056] The control logic of the opposite circuit can be referred to Table 1. In Table 1, PH3 represents the first photoelectric sensor, PH4 represents the second photoelectric sensor, PH5 represents the third photoelectric sensor, K11 represents the first normally open contact, and K12 represents the second normally open contact.

[0057] Table 1

[0058]

[0059] In Table 1, columns 2, 3, and 4 show 0 indicating no fabric was detected and 1 indicating fabric was detected. In column 5, 0 indicates no inner fabric was detected and 1 indicates inner fabric was detected.

[0060] When the first and second photoelectric sensors output a low level, and the third photoelectric sensor outputs a high level, it indicates that the fabric edge is positioned to the right. The opposite side circuit outputs a positive voltage to the opposite side motor, which then drives the upper host to move to the left. When the first photoelectric sensor outputs a low level, and the second and third photoelectric sensors output a high level, it indicates that the fabric edge is centered, and the upper host does not move. When the first, second, and third photoelectric sensors output a high level, it indicates that the fabric edge is positioned to the left. The opposite side circuit outputs a reverse voltage to the opposite side motor, which then drives the upper host to move to the right.

[0061] When the relay coil is energized, the signals output by the third photoelectric sensor and the miniature camera are sent to the opposite circuit, while the signals output by the first and second photoelectric sensors are not sent to the opposite circuit. At this time, the signals output by the third photoelectric sensor and the miniature camera control the voltage output to the opposite motor to be either a positive or reverse voltage.

[0062] When the third photoelectric sensor outputs a high level and the miniature camera outputs a low level, it indicates that the inner edge position is shifted to the right. The opposite side circuit outputs a positive voltage to the opposite side motor, which in turn drives the upper host to move to the left. When the third photoelectric sensor outputs a high level and the miniature camera outputs a high level, it indicates that the inner edge position is shifted to the left. The opposite side circuit outputs a reverse voltage to the opposite side motor, which in turn drives the upper host to move to the right.

[0063] When the third photoelectric sensor outputs a low level, the host computer does not operate regardless of whether the relay coil is energized or not, and regardless of whether the first photoelectric sensor, the second photoelectric sensor, and the miniature camera output a high level or a low level.

[0064] The relay coil can be powered either by pressing a physical button to turn on the power supply circuit, or by the controller outputting a level signal to power the relay coil.

[0065] In some embodiments, it also includes:

[0066] Record the R, G, and B components of multiple sets of images of the inner edge fabric;

[0067] Record the R, G, and B components of multiple sets of images of the outer fabric;

[0068] The threshold range is set based on the R, G, and B components of the images of the inner fabric in each group and the R, G, and B components of the images of the outer fabric in each group.

[0069] This embodiment records the R, G, and B components of multiple sets of images of inner edge fabric and multiple sets of images of outer edge fabric. Based on the recorded R components of the inner edge fabric images, an R component is set, and upper and lower thresholds are set for the R, G, and B components of the outer edge fabric images, resulting in multiple threshold ranges for the inner edge fabric. Each threshold range for the inner edge fabric includes the threshold range corresponding to the R component, the threshold range corresponding to the G component, and the threshold range corresponding to the B component. When identifying the inner edge fabric, it is determined whether the R, G, and B components of the image are within the corresponding threshold range of each inner edge fabric threshold range. When the R, G, and B components of the image are within the corresponding threshold range of any inner edge fabric threshold range, it indicates that inner edge fabric has been detected.

[0070] This embodiment can effectively handle situations where the fabric has patterns or multiple colors. When the inner edge fabric has patterns or multiple colors, the patterns or multiple colors of the inner edge can be grouped into one category, and each category has a set of inner edge fabric threshold ranges, thereby identifying the inner edge fabric and realizing the identification of multi-colored inner edge fabrics.

[0071] When the inner and outer colors of the composite fabric are significantly different, the method for identifying the inner fabric as described in the above embodiment can be used to distinguish between the inner and outer edges. When the inner and outer colors of the composite fabric are almost identical, the inner and outer edges can be distinguished by identifying factors such as the fabric's color, light reflection, material, and thickness.

[0072] In summary, the edge alignment method provided in this application can detect the inner edge fabric by acquiring and analyzing images. When the inner edge fabric is detected and when it is not detected, different first detection signals are output. Then, the edge alignment circuit controls the edge alignment motor to rotate forward or backward according to the first detection signal, thereby achieving alignment of the inner edge fabric.

[0077] In some embodiments, the processor 2 executes the computer program to specifically implement the following steps:

[0078] Determine the R component, G component, and B component of the image;

[0079] Determine whether the R component, the G component, and the B component are within the corresponding threshold ranges;

[0080] If the R component, the G component, and the B component are all within their respective threshold ranges, then the inner edge fabric is identified.

[0081] In some embodiments, the processor 2 executes the computer program to specifically implement the following steps:

[0082] Based on the recognition result, the first detection signal is output to the opposite edge switching circuit, so that the first detection signal is output to the opposite edge circuit through the opposite edge switching circuit; the opposite edge switching circuit is used to output the first detection signal or the second detection signal output by the photoelectric sensor to the opposite edge circuit; the photoelectric sensor is used to detect the position of the fabric or to detect whether there is fabric.

[0083] In some embodiments, the processor 2 executes the computer program to specifically implement the following steps:

[0084] If the inner fabric is detected, the first detection signal output will be high.

[0085] If the inner fabric is not detected, the first detection signal output will be low.

[0086] In some embodiments, the processor 2 executing the computer program further performs the following steps:

[0087] Record the R, G, and B components of multiple sets of images of the inner edge fabric;

[0088] Record the R, G, and B components of multiple sets of images of the outer fabric;

[0089] The threshold range is set based on the R, G, and B components of the images of the inner fabric in each group and the R, G, and B components of the images of the outer fabric in each group.

[0097] In some embodiments, the opposite-side device is installed on the dock of the fabric spreading machine. This prevents interference from the cutting blade's lifting and lowering during use, and also avoids interference during the fabric spreading process.

[0098] In some embodiments, the edge-matching system further includes an edge-matching switching circuit and photoelectric sensors. The photoelectric sensors include a first photoelectric sensor, a second photoelectric sensor, and a third photoelectric sensor. The first and second photoelectric sensors are used to detect the position of the fabric edge, and the third photoelectric sensor is used to detect whether there is fabric on the spreading machine. The first detection signal output by the miniature camera, the first photoelectric sensor, and the second photoelectric sensor are output to the edge-matching switching circuit, and the second detection signal output by the third photoelectric sensor is directly output to the edge-matching circuit.
