Description

Technical Field

[0001] This utility model relates to the field of glove manufacturing, and in particular to a glove gripping device. 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] The gloves need to be grasped during the turning process. For example, when loading gloves, the gloves need to be grasped to a designated position, or when opening the gloves, the two surfaces at the base of the gloves need to be grasped and then the base of the gloves needs to be opened.

[0004] Existing technology typically uses a needle-punched suction cup to grasp gloves. The needle-punched suction cup grasps and releases the gloves by extending and retracting the hook. When the hook extends, it inserts into the glove to grasp it, and when the hook retracts, it releases the glove.

[0005] However, the needle suction cup has the following defects during use:

[0006] 1. The extension length of the hook on the needle suction cup is difficult to adjust. Different gloves have different thicknesses, requiring different extension lengths of the hook on the needle suction cup, which need to be adjusted according to the actual situation. However, due to the small thickness of the gloves, it is difficult to achieve fine adjustment of the hook extension length within a small range.

[0007] Especially when opening gloves, two needle-pricked suction cups are needed to grip both sides of the glove to open it. At this time, the requirements for the length of the hook extension are even more stringent. If the hook extension is too long, the hook of one needle-pricked suction cup will hook onto both surfaces of the glove, making it difficult to open the glove. If the hook extension is too short, it will be difficult to effectively grip the glove.

[0008] 2. Crochet hooks are relatively thin and prone to damage such as chipping, bending, and breakage during use. Once a crochet hook is damaged, the gloves being handled will be damaged by the hook (for example, the glove's thread will be broken). In glove turning equipment, the turning process is generally automated with little human intervention. If crochet hook damage is not detected in time, it will lead to the damage of a large number of gloves, resulting in huge economic losses. Utility Model Content

[0039] 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.

[0040] This utility model embodiment provides a glove gripping device, such as Figure 1-3 As shown, it includes at least one set of clamping plate assemblies 1, each set of clamping plate assemblies 1 includes two clamping plates 2 and 3, the two clamping plates of the same clamping plate assembly are arranged opposite to each other, the clamping plate assembly 1 is connected to a clamping plate opening and closing mechanism 4 that controls the clamping and opening of the two clamping plates 2 and 3 of the clamping plate assembly 1, and a toothed structure 5 is provided on the end of the clamping plates 2 and 3 near the glove.

[0041] This invention uses a clamp-type gripping device instead of the needle-prick suction cup of the prior art. In use, the clamp assembly 1 is pressed onto the glove surface, and the toothed structures 5 at the ends of the clamps 2 and 3 contact the glove surface and press downwards. Then, the two clamps 2 and 3 are controlled to close, clamping the glove surface between them, thus achieving the gripping of the glove.

[0042] This utility model's glove gripping device can be used independently to grip gloves, enabling glove loading and movement. Alternatively, two glove gripping devices can be used together with their clamping plates arranged opposite each other. In this case, the clamping plates of the two glove gripping devices need to be staggered. Figure 7 As shown, two glove gripping devices grip the two surfaces of the glove respectively, keeping them relatively far apart, thus spreading the glove open at the base.

[0043] This invention avoids the difficulty of adjusting needle-punched suction cups for gloves of different thicknesses. A single gripping device can accurately grasp gloves of varying thicknesses, and it also prevents damage to the gloves caused by the hooks of the needle-punched suction cup. It has the advantages of being easy to use, simple to maintain, and providing excellent gripping performance.

[0044] This utility model does not limit the specific structural form of the toothed structure 5, as long as it can enable the glove to grasp. For example, its cross-section can be triangular, trapezoidal, semi-circular, semi-elliptical, etc.

[0045] As an improvement of this utility model embodiment, a pressure-bearing surface 6 is provided between two adjacent sets of clamping plate assemblies, and / or on the outermost clamping plate assembly. The pressure-bearing surface 6 is located away from the end of the toothed structure 5 from the glove to be grasped, and there is a set height difference between the pressure-bearing surface 6 and the end of the toothed structure 5.

[0046] When two glove gripping devices are used together, the clamps 2 and 3 of one glove gripping device are used to press against the pressure-bearing surface 6 of the other glove gripping device. To prevent damage from direct contact between the pressure-bearing surface 6 and the clamps 2 and 3, the surface of the pressure-bearing surface 6 has a flexible cushioning structure 7. The flexible cushioning structure 7 can be various soft padding structures.

[0047] In this invention, the pressure-bearing surface can be set on the clamping plates 2 and 3 and move with the clamping plates, or it can be fixed and not move.

[0048] This utility model does not limit the specific structural form of the clamp opening and closing mechanism 4. In one example, it includes a power cylinder 8 capable of generating linear displacement, such as a pneumatic cylinder or a hydraulic cylinder. The piston rod 9 of the power cylinder 8 is connected to a linkage mechanism, which is used to convert the extension and retraction motion of the piston rod 9 into a translational motion perpendicular to the direction of the extension and retraction motion.

[0049] The number of linkage mechanisms can be two, with the two linkage mechanisms located on both sides of the piston rod 9 respectively. The two linkage mechanisms convert the extension and retraction motion of the piston rod 9 into a translational motion that is symmetrically located on both sides of the piston rod 9 and perpendicular to the direction of the extension and retraction motion.

[0050] Specifically, the linkage mechanism includes a transmission rod 10, a lever 11, and a slider 12. One end of the transmission rod 10 is hinged to the piston rod 9 through an elongated hole 13, and the other end of the transmission rod 10 and the lever 11 are fixed on a rotating shaft 14. The rotating shaft 14 is set in a fixed position and can rotate in the fixed position.

[0051] The slider 12 is set on the slider track 15, which is perpendicular to the direction of telescopic movement. The toggle block 11 is connected to the slider 12 and moves the slider 12 to slide along the slider track 15.

[0052] For example, a toggle slot 16 can be provided on the slider 12, and the end of the toggle block 11 extends into the toggle slot 16 to move the slider 12.

[0053] Thus, through the transmission of the transmission rod 10, the lever 11 and the slider 12, the extension and retraction motion of the piston rod 9 is converted into the translational motion of the slider 12 along the slider track 15.

[0054] Then, at least one clamping plate of each clamping plate assembly can be connected to the slider 12 to realize the translational movement of the clamping plate along the slider track 15 and control the opening and closing of the clamping plate.

[0055] Please note that the connection between the clamping plate and the slider 12 described in this utility model can mean either that the slider 12 and the connected clamping plate are separate structures connected together, or that the slider 12 and the connected clamping plate are integrally formed structures that move together.

[0056] This utility model does not limit the number of clamping plate assemblies; several specific examples are given below:

[0057] Example 1:

[0058] like Figure 1-3 As shown, the number of clamping plate assemblies 1 is one set; one clamping plate 2 or 3 of clamping plate assembly 1 is connected to a slider 12, and the opening and closing of clamping plate 2 or 3 is realized by controlling one clamping plate 2 or 3 through one slider 12.

[0059] Alternatively, the two clamping plates 2 and 3 of the clamping plate assembly 1 can be connected to two sliders 12 respectively, and the two clamping plates 2 and 3 can be controlled by the two sliders 12 to realize the opening and closing of the clamping plates.

[0060] In this example, the pressure-bearing surface 6 can be located on the outside of one or both clamps of the clamp assembly 1.

[0061] Example 2:

[0062] like Figure 4 , 5 As shown, there are two sets of clamping plate assemblies 1-1 and 1-2, and there is a set spacing between adjacent clamping plate assemblies 1-1 and 1-2.

[0063] Each of the inner clamping plates 2-2 and 3-2 of the two clamping plate assemblies 1-1 and 1-2 is connected to two sliders 12. The two sliders 12 control the two inner clamping plates 2-2 and 3-2 to open and close the clamping plates.

[0064] Alternatively, one clamping plate 2-1 and 3-1 on the outer side of each of the two clamping plate assemblies 1-1 and 1-2 can be connected to two sliders 12 respectively, and the two outer clamping plates 2-1 and 3-1 can be controlled by the two sliders 12 to realize the opening and closing of the clamping plates.

[0065] In this example, the pressure-bearing surface 6 can be located between the two sets of clamping plate assemblies 1-1 and 1-2, or it can be located on the outside of at least one set of clamping plate assemblies 1-1 and 1-2; or both.

[0066] Example 3:

[0067] like Figure 6As shown, there are three sets of clamping plate assemblies: 1-3, 1-4, and 1-5, with a set spacing between adjacent clamping plate assemblies. The two clamping plates 2-3 and 3-3 of the middle clamping plate assembly 1-3 are connected to two sliders 12 respectively. The two sliders 12 control the two clamping plates 2-3 and 3-3 to open and close the clamping plates of the middle clamping plate assembly 1-3.

[0068] Furthermore, the outer clamping plates 2-4 and 3-5 of the clamping plate assemblies 1-4 and 1-5 on the left and right sides are connected to the clamping plates 2-3 and 3-3 on the left and right sides of the clamping plate assembly 1-3 in the middle, respectively. That is, clamping plates 2-3 and 2-4 are connected together and move together through a slider 12; clamping plates 3-3 and 3-5 are connected together and move together through another slider 12.

[0069] In this example, the pressure-bearing surface 6 is located between the middle clamping plate assembly 1-3 and the left and right clamping plate assemblies 1-4 and 1-5.

[0070] 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.
