Subsequent operators can then conveniently retrieve the cashmere products from the buffer zone to the working area without waiting, greatly saving time. Furthermore, the PLC controller performs a count every time the pusher plate component moves, thus allowing for the evaluation of each operator's work efficiency without requiring manual scanning and counting by the operator.

Description

Technical Field

[0001] This application relates to the field of cashmere product manufacturing technology, specifically to a manual quality inspection station for cashmere products. Background Technology

[0002] Due to the high value and special nature of cashmere products, machines cannot accurately sort them 100% (due to the presence of coarse wool or impurities). Therefore, manual quality inspection is irreplaceable in the short term. Manual quality inspection mainly checks for holes, missed stitches, horizontal stripes (machine sensors are not sensitive to light-colored cashmere), and the feel of the fabric (such as whether it meets the "smooth" standard). In addition, the manual inspection station also undertakes the task of trimming excess threads.

[0003] In existing technologies, such as the wool sweater quality inspection platform disclosed in patent number CN202321646549.9, the problem of mixed inspection and uninspected cashmere sweaters during the quality inspection process is avoided by setting up a first conveyor belt and a second conveyor belt, and the problem of recording the number of quality inspectors by setting up a barcode scanner is also avoided. However, the efficiency of this device is low in actual use. For example, the operator needs to frequently get up to pick up the uninspected cashmere sweaters on the upper conveyor belt, and sometimes the operator on the back workbench has to wait a long time for the uninspected cashmere sweaters to be conveyed by the conveyor belt because the operator at the front workbench has to pick up the uninspected cashmere sweaters on the conveyor belt. There are also problems such as the extra time occupied by the barcode scanner scanning process. Further optimization is needed. Utility Model Content

[0004] In view of the above problems, this application provides a manual quality inspection station for cashmere products, which can facilitate manual quality inspection of cashmere products and further improve efficiency, eliminating the need for operators to manually scan and count.

[0005] According to one aspect of the embodiments of this application, a manual quality inspection station for cashmere products is provided. The manual quality inspection station for cashmere products includes a PLC controller and a first belt conveyor and a second belt conveyor symmetrically arranged. A third belt conveyor is disposed on top of the second belt conveyor. Multiple operating tables are disposed between the first and second belt conveyors, and the multiple operating tables are sequentially spaced along the axial direction of the first and second belt conveyors. The top end face of each operating table, from the first belt conveyor to the second belt conveyor, is sequentially divided into a buffer zone and a working zone. The buffer zone is connected to a support of the first belt conveyor via a ramp. Multiple push plate components, each corresponding to one of the operating tables, are disposed on the side of the first belt conveyor away from the operating tables. An infrared sensor is disposed on one side of each push plate component. A pressure sensor is disposed on the top end face of the buffer zone. The pressure sensor, the infrared sensor, and the push plate components are all electrically connected to the PLC controller.

[0006] In some embodiments, a first vertical plate is provided on both sides of the buffer zone at the top of the operating table, and the two first vertical plates expand outward from the end near the first belt conveyor to form a trumpet shape.

[0007] In some embodiments, a second vertical plate is provided on one side of the first belt conveyor between two adjacent first vertical plates on different operating platforms, and the ends of the first vertical plate and the second vertical plate are smoothly connected.

[0008] In some embodiments, the push plate component includes a triangular support frame disposed on the side of the first belt conveyor away from the operating table, and at least one cylinder assembly is disposed on the triangular support frame, the free end of the cylinder assembly facing the operating table and connected to a movable plate.

[0009] In some embodiments, the first belt conveyor and the second belt conveyor have opposite conveying directions.

[0010] In some embodiments, a desk lamp component and a negative pressure absorption table are provided on the operating table in the work area. The negative pressure absorption table includes a negative pressure hopper formed on the operating table. A grid is provided on the top of the negative pressure hopper. The top end face of the grid is flush with the top end face of the work area. The bottom ends of multiple negative pressure hoppers are connected to a negative pressure pipe.

[0011] The beneficial effects of this application are as follows: In this embodiment, by setting up a first belt conveyor, a second belt conveyor, and a third belt conveyor, as well as an operating table, the first belt conveyor is used to transport cashmere products to be inspected. After quality inspection is completed at the operating table, the operator can place the sorted cashmere products onto the second or third belt conveyor respectively. Those that cannot be quickly repaired are placed on the third belt conveyor. Since cashmere products that cannot be quickly repaired only account for a small portion, the operator does not need to get up frequently. In this application, a buffer zone and a work area are also set up. The push plate component and infrared sensor work together so that during the operation, when the operator is inspecting the cashmere products to be inspected in the work area, the push plate component can automatically push the cashmere products to be inspected on the first belt conveyor to the buffer zone. Subsequently, the operator can conveniently take the cashmere products to be inspected in the buffer zone to the work area without waiting, which greatly saves time. Moreover, the PLC controller can count once for each action of the push plate component, so that the work efficiency of each operator can be evaluated without the need for the operator to manually scan and count.

The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and the foregoing description of the accompanying drawings are intended to cover non-exclusive inclusion.

[0016] For details, please refer to Figures 1 to 2 , Figure 1 This is a schematic diagram of the overall structure of the manual quality inspection station for cashmere products provided in an embodiment of this application. Figure 2This is a schematic diagram of the overall cross-sectional structure of the equipment provided in this application embodiment. The cashmere product manual quality inspection station 100 includes a PLC controller and symmetrically arranged first conveyor belt 110 and second conveyor belt 120. The first conveyor belt 110 is used to transport cashmere products to be inspected to various operating tables 140. Cashmere products include cashmere sweaters, cashmere blankets, etc. The second conveyor belt 120 is used to transport cashmere products that have completed quality inspection to the outside of the equipment. The feeding of the first conveyor belt 110 can be done manually by the operator or automatically by the machine gripper. During the feeding process, the cashmere products are placed in wooden frames or plastic baskets. It should be noted that there should be a certain gap between the two feeding processes. A third conveyor belt 130 is provided on the top of the second conveyor belt 120. The third conveyor belt 130 is used to transfer cashmere products that cannot be repaired. Multiple operating platforms 140 are arranged between the first conveyor belt 110 and the second conveyor belt 120. These platforms are spaced apart sequentially along the axial direction of the first and second conveyor belts 110 and 120. Each platform 140 is equipped with an operator. After completing quality inspection, the operator places the cashmere products on the second conveyor belt 120. If the cashmere products have irreparable defects such as holes, they can be placed on the third conveyor belt 130. The top surface of the operating platform 140, from the first conveyor belt 110 to the second conveyor belt 120, consists of a buffer zone 141 and a working area 142. The buffer zone 141 is connected to the support of the first conveyor belt 110 via a ramp 143. The cashmere products to be inspected on the first conveyor belt 110 are conveyed to the buffer zone 141 via a pusher plate component 150. After the operator completes quality inspection and classification of the cashmere products in the working area 142, they retrieve the cashmere products to be inspected from the buffer zone 141 for further quality inspection. On the side of the first conveyor belt 110 away from the operating table 140, multiple pusher components 150, each corresponding to the operating table 140, are provided. The pusher components 150 are used to push cashmere products on the first conveyor belt 110 to a buffer zone 141 for temporary storage. An infrared sensor 160 is provided on one side of each pusher component 150 to detect whether any cashmere products to be inspected are passing through. A pressure sensor 141a is provided on the top surface of the buffer zone 141 to detect the pressure on its top, further determining whether any cashmere products to be inspected are present in the top buffer zone 141. The pressure sensor 141a, the infrared sensor 160, and the pusher components 150 are all electrically connected to a PLC controller.

[0017] In this embodiment of the application, during the operation, there are two cashmere products to be inspected on each operating table 140 at the same time, one located in the buffer zone 141 and the other in the work area 142. After the operator completes the quality inspection of the cashmere products to be inspected in the work area 142, the cashmere products can be placed on the second conveyor belt 120 or the third conveyor belt 130 according to their quality. Then, the cashmere products to be inspected in the left buffer zone 141 are taken out. At this time, the pressure sensor 141a of the left buffer zone 141 detects the pressure change and feeds it back to the PLC controller in the form of an electrical signal. When the infrared sensor 160 corresponding to the operating table 140 on the first conveyor belt 110 detects that a cashmere product to be inspected has passed by, the PLC controller sends a command to the push plate component 150. The push plate component 150 pushes the cashmere products to be inspected on the first conveyor belt 110 into the buffer zone 141. The PLC controller can have a built-in counting module, which counts once every time it controls the push plate component 150 to move, thereby calculating the number of quality inspections by the operators at each workstation.

[0018] As can be seen from the above, in this embodiment, by setting up a first conveyor belt 110, a second conveyor belt 120, and a third conveyor belt 130, as well as an operating table 140, the first conveyor belt 110 is used to transport cashmere products to be inspected. After quality inspection is completed at the operating table 140, the operator can place the sorted cashmere products onto the second conveyor belt 120 or the third conveyor belt 130 respectively. Those that cannot be quickly repaired are placed on the third conveyor belt 130. Since the cashmere products that cannot be quickly repaired only account for a small portion, the operator does not need to get up frequently. In this application, a buffer zone 141 and a work area 142 are also set up. The push plate component 150 and the infrared sensor 160 work together to allow the push plate component 150 to automatically push the cashmere products to be inspected on the first conveyor belt 110 to the buffer zone 141 when the operator is inspecting the cashmere products to be inspected in the work area 142. The operator can then conveniently take the cashmere products to be inspected from the buffer zone 141 to the work area 142 without waiting, which greatly saves time. In addition, the PLC controller can count once for each action of the push plate component 150, so that the work efficiency of each operator can be evaluated without the need for the operator to manually scan and count.

[0019] In some embodiments, first vertical plates 141b are respectively provided on both sides of the buffer zone 141 at the top of the operating table 140. The two first vertical plates 141b expand outward from the end near the first belt conveyor 110, forming a trumpet shape. In this embodiment, through the above arrangement, the two first vertical plates 141b form a trumpet-shaped opening, which facilitates the guidance of the cashmere products to be tested. This ensures that even if the opening of the push plate component 150 has errors, the cashmere products to be tested can still be accurately conveyed to the buffer zone 141, and prevents the cashmere products to be tested from sliding down the top sides of the operating table 140.

[0020] In some embodiments, a second vertical plate 111 is provided between two adjacent first vertical plates 141b on different operating tables 140 on one side of the first conveyor belt 110, and the ends of the first vertical plates 141b and the second vertical plate 111 are smoothly connected. In this embodiment, the second vertical plate 111 is provided to prevent the cashmere products to be tested from slipping down the side of the first conveyor belt 110.

[0021] In some embodiments, the pusher component 150 includes a triangular support frame 151 disposed on the side of the first conveyor belt 110 away from the operating table. At least one cylinder assembly 152 is disposed on the triangular support frame 151, with the free end of the cylinder assembly 152 facing the operating table 140 and connected to a movable plate 153. This application embodiment illustrates a specific arrangement of the pusher component 150. During operation, the cylinder extends, driving the movable plate 153 forward. Further, the movable plate 153 pushes the wooden frame containing the cashmere product to be tested, causing it to fall into the buffer zone 141.

[0022] In some embodiments, the first conveyor belt 110 and the second conveyor belt 120 convey in opposite directions. In this embodiment, the above arrangement prevents the mixing of cashmere products to be inspected and those already inspected.

[0023] In some embodiments, a desk lamp component 142a and a negative pressure absorption platform are provided on the work area 142 of the worktable 140. The negative pressure absorption platform includes a negative pressure hopper 142b formed on the worktable, and a grid mesh 142c is provided on the top of the negative pressure hopper 142b. The top end face of the grid mesh 142c is flush with the top end face of the work area 142. The bottom ends of multiple negative pressure hoppers 142b are connected to a negative pressure pipe 142d. In this embodiment, the operator can cut off excess threads from cashmere products at the worktable 140 and feed them into the grid mesh 142c. Under the action of the negative pressure pipe 142d, the threads will be absorbed and collected.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
