Description

Technical Field

[0001] This utility model relates to the field of glove production, and in particular to a glove flipping and waste removal mechanism. Background Technology

[0002] Gloves are a widely used type of work protection product. They are generally produced by knitting gloves using glove knitting machines. After the gloves are produced by the glove knitting machine, they undergo subsequent processes, such as identifying defective gloves using automatic visual recognition equipment, bundling gloves using automatic glove bundling and packaging equipment, and turning gloves over using automatic glove turning equipment.

[0003] A hand mold is used during the glove flipping process. The glove is placed over the flipping hand mold, and then flipped onto the material handling hand mold using a flipping lever or frame. Because the glove is a flexible structure, there are instances where the glove cannot be correctly fitted onto the flipping hand mold; in such cases, the glove must be removed to prevent interference with subsequent glove flipping. Additionally, gloves with tears or other defects must also be removed. Utility Model Content

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] This utility model provides a glove turning and waste removal mechanism, which can be applied to a standalone glove turning device or to a fully automatic glove turning and bundling device that integrates a glove turning device. Figure 1-8 As shown, the device includes a flipped hand mold 1 and a scraper 2 for removing waste. The flipped hand mold 1 is equipped with a camera that detects whether the gloves on the flipped hand mold 1 need to be removed, and the camera is connected to a data processing device. The scraper 2 is connected to a drive mechanism that drives the scraper 2 to move in a direction perpendicular to the plane where the flipped hand mold 1 is located and in the direction of the fingers of the flipped hand mold 1.

[0027] The camera includes a first set of camera units 3, which are positioned diagonally above the flipped hand mold 1. The field of view of the first set of camera units 3 covers the fingertips of the glove on the flipped hand mold 1 and at least a portion of the upper surface of the glove.

[0028] This invention uses a camera to capture images of a glove placed on a flipped hand mold, and then processes the images using data processing equipment to determine whether the glove is correctly placed on the mold and whether it has any defects such as damage. If the glove is detected as not correctly placed on the mold or has defects such as damage, it needs to be removed.

[0029] Data processing equipment can make judgments using various image processing methods in the existing technology. Image detection methods can be various methods disclosed in the existing technology, such as methods based on neural networks.

[0030] Research has shown that when the glove is correctly fitted onto the flipped hand mold, the five fingers of the glove fit over the five fingers of the flipped hand mold, and the glove extends all the way to the flipped hand mold, meaning the ends of the five fingers of the flipped hand mold and the ends of the five fingers of the glove fit tightly together. Even through the glove, the shape and outline of the end faces of the five fingers of the flipped hand mold can be clearly seen, such as... Figure 1-3As shown in the image. Therefore, the image of the fingertips can be used to detect whether the glove is correctly fitted onto the flipped hand mold.

[0031] Furthermore, the gloves turned over by the glove turning machine are gloves knitted by a glove knitting machine. When knitting gloves, the final take-up point is at the fingertips. Therefore, if defect 2 exists in the knitted glove, it will manifest at the fingertips. For example, if the take-up is unsuccessful, there will be holes or tears at the fingertips (e.g.,...). Figure 2 , 3 As shown), for example, when there is a broken or missing thread, there will be a missing thread at the tip of the finger (e.g. Figure 1 (The second finger from the left is missing a thread). Therefore, the presence of defects in the glove can also be detected through images of the fingertips.

[0032] Based on this, the present invention tilts the first camera unit 3 of the camera to capture images of the fingertips of the glove on the flipped hand mold 1 (including at least a portion of the upper surface image), and uses the images to determine whether the glove is correctly placed on the flipped hand mold and whether the glove has any defects.

[0033] The above judgment can be made using a convolutional neural network (CNN). After training the CNN with a large number of samples, it can be used to judge new input images. The CNN can not only determine whether gloves need to be removed, but also determine the type of gloves, such as whether they are not correctly fitted onto the flipped hand mold or have defects. The structure, training method, and detection method of the CNN are conventional techniques disclosed in the prior art, and will not be elaborated upon in this invention.

[0034] In use, this invention uses a first set of camera units to detect the gloves on the flipped hand mold. If the gloves are not correctly fitted onto the flipped hand mold or are damaged, they need to be removed. At this time, the drive mechanism controls the waste removal scraper 2 to move towards the flipped hand mold 1 along a plane perpendicular to it. Once in position, the drive mechanism controls the waste removal scraper 2 to move relative to the fingers of the flipped hand mold 1, scraping the gloves off the mold.

[0035] This invention enables automated removal of waste from gloves on a flipped hand mold, improving the automation of the glove flipping process, reducing manual intervention, and increasing production efficiency. Furthermore, its structure is simple and easy to operate. In addition, this invention uses a tilted first set of camera units to capture images of the fingertips of the glove on the flipped hand mold, and uses these images to determine whether the glove needs waste removal, demonstrating high accuracy.

[0036] This utility model provides a waste removal receiving device 4 below the flipped hand mold 1, and a removal device for removing gloves from the waste removal receiving device 4.

[0037] The removal device includes an air inlet 5, which is connected to an air source. Alternatively, the removal device can also be a scraper, conveyor belt, or other similar mechanism.

[0038] The waste removal receiving device 4 has a waste removal outlet 6 on one side, and the air blowing hole 5 is located on at least one side of the waste removal receiving device 4 other than the waste removal outlet 6.

[0039] For example, it can be set on the opposite side of the waste removal outlet 6 to blow the gloves out of the waste removal outlet 6. It can also be set on the adjacent side of the waste removal outlet 6 to blow air from multiple directions to ensure that the gloves are blown out of the waste removal outlet 6.

[0040] Specifically, the waste removal receiving device 4 includes a receiving plate 7, one side of the receiving plate 7 is a waste removal outlet 6, and the side of the receiving plate 7 other than the waste removal outlet 6 is provided with a blocking structure 8, and the air blowing hole 5 is provided on at least one side of the blocking structure 8.

[0041] The blocking structure is used to prevent gloves from falling into the machine from other sides of the receiving plate 7. The blocking structure can be a set baffle or other structures of the machine that act as blocking structures.

[0042] This utility model does not limit the specific structural form of the waste removal scraper 2. Several examples are given below:

[0043] Example 1:

[0044] like Figure 8 As shown, the scraper 2 has a flat plate structure on the side near the flipped hand mold 1. It scrapes the glove off by relying on the flat surface of the plate structure to contact the flipped hand mold.

[0045] Furthermore, soft materials such as rubber or silicone can be applied to the edges of the flat structure to reduce mechanical noise and improve scraping performance. Materials with self-lubricating properties, such as polytetrafluoroethylene (PTFE), can also be used to enhance lubrication of the contact surfaces.

[0046] Example 2:

[0047] like Figure 6 As shown, the scraper 2 has a finger-operated paddle 9 on the side near the flipped hand mold 1. The finger-operated paddle 9 is used to insert between the fingers of the flipped hand mold 1 to ensure reliable scraping of the glove. In this example, the finger-operated paddle 9 is a flat, block-shaped structure.

[0048] Example 3:

[0049] like Figure 7As shown, this example is similar to Example 2, except that the end of the finger-grip block 9 has a hook structure 10 that bends towards the fingertips of the flipped hand mold 1. When scraping the glove, the hook structure 10 hooks onto the base of the glove to prevent slippage and further ensure the scraping effect. The angle of the hook structure 10 can be set according to the actual situation to ensure both the scraping effect and that the scraped glove can easily fall onto the waste receiving device 4, preventing the hook structure 10 from getting stuck on the glove and making it difficult to fall.

[0050] The driving mechanism includes a first driving unit 11 that drives the waste removal scraper 2 to move perpendicular to the plane of the flipping hand mold 1, and a second driving unit (not shown in the figure) that drives the waste removal scraper 2 to move along the finger direction of the flipping hand mold 1.

[0051] As an improvement of this utility model embodiment, the aforementioned camera further includes a second set of camera units 12 and / or a third set of camera units 13. The second set of camera units 12 and the third set of camera units 13 are located above and below the flipped hand mold 1, respectively. The field of view of the second set of camera units 12 and the third set of camera units 13 covers the upper and lower surfaces of the glove covered on the flipped hand mold 1.

[0052] Images from the second set of camera units 12 and the third set of camera units 13 supplement those from the first set of camera units, detecting the complete upper and lower surfaces of the glove to achieve comprehensive detection.

[0053] The above embodiments of this utility model can be applied to a single-station glove turning machine, such as... Figure 8 As shown, it can also be applied to multi-station glove turning machines, such as... Figure 5 As shown.

[0054] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
