Description

Technical Field

[0001] The utility model relates to the field of operation and transportation, further to the field of sorting, in particular to the field of sorting according to the characteristics of objects, and more particularly to a clothing sorting system. Background Art

[0002] At present, automatic code scanning and sorting systems have become popular in the logistics industry. Automatic code scanning replaces manual scanning, and automatic sorting replaces manual sorting, which improves the efficiency of sorting and shipping. The clothing industry has also begun to introduce automatic code scanning and sorting systems to improve the sorting and shipping efficiency of clothing products. However, some processes in the clothing production process, such as needle detection, cannot be well compatible with them.

[0003] With the improvement of modern industrial level and the continuous pursuit of production efficiency in the garment industry, industrial sewing machines can now achieve ultra-high-speed sewing of more than 7,000 rpm. A small sewing error can cause a broken needle, which may be mixed into clothing and flow into the market, causing not only consumer injuries and huge compensation claims, but also brand reputation damage. Therefore, at present, high-quality brands cannot accept the entry of metal foreign bodies such as broken needles into the market.

[0004] In the garment manufacturing industry, to prevent the contamination of metal foreign objects such as broken needles and screws, a needle detection process is added before sorting. This process uses a needle detector to inspect each item for needles and identify any metallic foreign objects. However, this process is manually performed. Upon detecting a garment containing a metallic foreign object (such as a broken needle), the needle detector typically automatically stops and issues an alarm, or the conveyor belt rotates and ejects the item, awaiting manual inspection and removal. Existing automatic barcode scanning and sorting systems are incompatible with the needle detection process, resulting in low production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a clothing sorting system, which aims to solve the technical problem that the automatic code scanning sorting system in the prior art is difficult to be compatible with the needle detection process in the clothing production industry.

[0006] The utility model provides a clothing sorting system, comprising a needle detection unit, an image recognition unit and a sorting unit; the needle detection unit comprises a needle detection channel and a first conveyor belt, the first conveyor belt passes through the needle detection channel, and magnetic probes are respectively provided on the upper and lower sides of the needle detection channel; the image recognition unit comprises an image recognition channel and a second conveyor belt, the second conveyor belt passes through the image recognition channel, and an image recognition device is provided above the image recognition channel, including a camera; the sorting unit comprises a sorting table, a sorting device is provided on the sorting table, and one or more sorting grids and one or more rejecting grids are provided on the edge of the sorting table; the outlet of the first conveyor belt is close to the inlet of the second conveyor belt, and the outlet of the second conveyor belt is close to the inlet of the sorting table.

[0007] Furthermore, the first conveyor belt and the second conveyor belt are belt conveyor belts, and the sorting device is a pendulum wheel sorting device.

[0008] Furthermore, the sorting opening and the rejecting opening are downward slopes.

DETAILED DESCRIPTION

[0020] The following examples will further illustrate the present invention, but are not intended to limit the present invention. Example

[0021] like Figure 1 As shown, the system is composed of a needle detection unit 1, an image recognition unit 2 and a sorting unit 3. The needle detection unit 1, the image recognition unit 2 and the sorting unit 3 are respectively equipped with separate control devices (not shown in the figure), and these control devices are interconnected through signal lines to achieve information transmission and interaction.

[0022] The needle detection unit 1 includes a needle detection channel 101 and a first conveyor belt 4. The first conveyor belt 4 passes through the needle detection channel 101. The first conveyor belt 4 is a belt conveyor belt. Magnetic probes are respectively installed on the upper and lower sides of the needle detection channel 101. When the goods pass through the needle detection channel 101 through the first conveyor belt 4, the principle of feedback generated when metal cuts the magnetic lines of force is used to identify unqualified goods with metal foreign matter.

[0023] At the same time, the controller of the needle detection unit 1 counts the number of unqualified products and transmits the information of the unqualified products to the controller of the image recognition unit 2 .

[0024] The image recognition unit 2 includes an image recognition channel 201 and a second conveyor belt 5. The second conveyor belt 5 is also a belt conveyor belt. The entrance of the second conveyor belt 5 is connected with the exit of the first conveyor belt 4 to receive the goods transmitted by the first conveyor belt 4; the second conveyor belt 5 passes through the image recognition channel 201. An image recognition device is arranged above the image recognition channel 201. A structure similar to a gantry can be set up to install the image recognition device above the second conveyor belt 5, so that the image recognition device can collect images of the goods. The shooting range of the image recognition device can just cover the width of the image recognition channel 201.

[0025] The image recognition device can capture images through a combination of one or more devices such as a camera, a laser scanner, an RFID reader, etc., and can adapt to cargo information on various carriers, such as one-dimensional barcodes, two-dimensional codes, text, RFID chips, etc.; the camera can not only recognize one-dimensional barcodes and two-dimensional codes, but also recognize text cargo information through OCR character recognition technology, thereby further expanding the recognition range.

[0026] The image recognition unit 2 can identify information content including but not limited to product number, size, color, batch, operator, etc.; a display screen 202 is provided on the image recognition unit 2, and the signal receiving end of the display screen 202 is electrically connected to the signal output end of the control device of the image recognition unit 2. According to the unqualified product information transmitted from the control device of the needle detection unit 1 and combined with the goods information recognized by the image recognition unit 2, the control device of the image recognition unit 2 can respectively bind qualified products and unqualified products with their corresponding identification information, and display the identification information in the form of a list on the display screen 202 after performing list statistics, thereby intuitively displaying the relevant information of qualified products and unqualified products, and then quickly locating the problem equipment, and carrying out repairs and tracing in time to avoid the increase of unqualified products; the control device of the image recognition unit 2 transmits the identification information and unqualified product information to the control device of the sorting unit 3.

[0027] The sorting unit 3 includes a sorting table 303, on the surface of which a pendulum-type sorting device is installed. The entrance of the sorting table 303 is closely connected to the exit of the second conveyor belt, and receives goods from the second conveyor belt 5. Two sorting grids 301 and a rejection grid 302 are set at the edge of the sorting table 303. The pendulum-type sorting device is composed of a plurality of pendulum units. The pendulum units on the sorting device 6 through which the goods pass rotate under the control of a control device, thereby adjusting the conveying direction of the guide wheels on the pendulum units. According to preset sorting rules, the goods are selectively sorted into the sorting grid 301 or the rejection grid 302 by the rolling of the guide wheels, where qualified products are sorted into the sorting grid 301 and unqualified products are sorted into the rejection grid 302. The exits of all grids are provided with transfer boxes or transfer carts for loading goods. The sorting grid 301 and the rejection grid 302 are both downwardly sloped to facilitate the sliding of goods into the transfer boxes or transfer carts.

[0028] In this embodiment, the sorting rules of the two sorting grids 301 are two different colors, or different batches, different sizes, or different colors. The number of sorting grids 301 can also be more than two, and can be added according to different rules; but there must be more than one rejection grid 302 for sorting unqualified products.

[0029] The control device of the sorting unit 3 also optimizes the sorting grid 301 corresponding to the flow direction of goods by statistically analyzing high-frequency flow data, adjusts the operating speed in real time, and dynamically adjusts the sorting strategy by using a learning algorithm, thereby continuously improving the sorting efficiency.

[0030] like Figure 2 As shown, the working method of the clothing sorting system in this embodiment is as follows:

[0031] Step 1: Place the goods at the entrance of the first conveyor belt 4. The goods pass through the needle detection channel 101 of the needle detection unit 1 to detect metal foreign matter in the goods. If there is metal foreign matter in the goods, the goods are judged as unqualified and counted. At the same time, the relevant data is transmitted to the image recognition unit 2; then proceed to step 2;

[0032] Step 2: The goods are transferred from the first conveyor belt 4 to the second conveyor belt 5 and enter the image recognition unit 2. The image recognition device in the image recognition channel 201 recognizes and records the identification information on the goods. Combined with the defective product information transmitted from the control device of the needle detection unit 1, the qualified and defective products are respectively bound to their corresponding identification information, and the identification information is displayed on the display screen 202 in the form of a list after statistics. Goods with unrecognizable information or incorrect identification information are also determined to be defective and the defective products are counted. The image recognition unit 2 transmits the identification information and defective product information to the sorting unit 3. When the goods are defective, the process proceeds to step 3; when the goods are qualified, the process proceeds to step 4.

[0033] Step 3: The goods are transferred to the sorting device 6 via the second conveyor belt 5 and enter the sorting unit 3. Combining the identification information and the defective product information transmitted by the image recognition unit 2, the defective products are conveyed to the rejection opening 302 to complete the sorting.

[0034] Step 4: The goods are transferred to the sorting device 6 via the second conveyor belt 5 and enter the sorting unit 3. According to the identification information transmitted by the image recognition unit 2 and the sorting rules preset by the sorting unit 3, qualified goods are sorted into the sorting grid 301 corresponding to the rules, completing the sorting. Example

[0035] This embodiment is a preferred solution of embodiment one, and the rejection grid 302 includes a first rejection grid 302 and a second rejection grid 302. Unqualified products with metal foreign matter are sorted to the first rejection grid 302; unqualified products with unrecognizable information or incorrect identification information are sorted to the second rejection grid 302 to prevent unqualified products with metal foreign matter from mixing with normal goods and flowing out. Example

[0036] This embodiment is a preferred solution of embodiment one. The sorting grid 301 and the rejection grid 302 are provided with full box sensors and counting sensors; the counting sensors can record the number of goods passing through the grid, and transmit the information to the control device of the image recognition unit 2, which is then transmitted to the display screen 202 of the image recognition unit 2 via the control device of the image recognition unit 2 for display; the full box sensor senses the goods that cannot slide out of the grid when the circulation box or circulation vehicle is full, and issues an alarm to avoid accumulation of goods in the grid.
