AI Technical Summary
In existing technology, when the number of rubber band struts is inconsistent, the rubber bands cannot be properly fitted onto the stack of gloves, resulting in the failure of the glove stacking loop.
Touch sensors are used to detect whether the rubber band is fully supported on the four rubber band support rods. If it is not fully supported, the clamping process is stopped. Limit blocks and guide ramps control the separation of the rubber band from the support rods to ensure that the rubber band is properly clamped.
This improved the success rate of glove stacking and clamping, prevented clamping failure, and ensured the smooth progress of subsequent processes.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove production, and in particular to a device for securing elastic bands to stack gloves. 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] Chinese patent document CN221091370U discloses a longitudinally stacked glove elastic band binding device, which uses an elastic band support rod to open the elastic band and uses a limiting block on a limiting frame to separate the elastic band from the elastic band support rod, thus securing the elastic band to the stacked gloves.
[0004] The above solution has the following problems:
[0005] There are four rubber band support poles, but the rubber bands cannot always be correctly fitted onto all four poles. For example, there may be situations where the rubber bands are fitted onto three poles, two poles, or hanging on only one pole. In these cases, the rubber bands cannot be fitted onto the stack of gloves, causing the glove stacking to fail. Utility Model Content
[0006] To address the problems of existing technologies, this utility model provides a device for securing stacked gloves with elastic bands, which improves the success rate of securing stacked gloves with elastic bands.
[0007] The technical solution provided by this utility model is as follows:
[0008] A device for securing stacked gloves with elastic bands includes an elastic band support structure and a glove stack support platform for carrying stacked gloves. The elastic band support structure and the glove stack support platform have relative movement that moves closer to or further away from each other.
[0009] The elastic band support structure includes four elastic band support rods for receiving and expanding the elastic bands, with the four elastic band support rods facing one side of the glove stack support platform;
[0010] A first set of limiting blocks is provided between the elastic band support structure and the glove stack support platform. The first set of limiting blocks is used to make the elastic band separate from the elastic band support rod and tighten the stack of gloves after the stack of gloves is put into the open elastic band.
[0011] A touch sensor is provided between the first set of limiting blocks and the rubber band support structure to detect whether the rubber band is fully supported on the four rubber band support rods.
[0012] Furthermore, the touch sensor includes a touch spring for contacting the extended rubber band.
[0013] Furthermore, the number of touch sensors is at least two, and the at least two touch sensors are distributed at least at the positions of two opposite sides of the stretched rubber band to detect at least two opposite sides of the stretched rubber band.
[0014] Furthermore, there are four touch sensors, which are distributed at the four corners of the stretched rubber band.
[0015] Furthermore, a second set of limiting blocks is provided between the touch sensor and the rubber band support structure. The second set of limiting blocks is used to cause the rubber band to detach from the rubber band support rods and fall down when the touch sensor detects that the rubber band is not fully supported on the four rubber band support rods.
[0016] Furthermore, both the first set of limiting blocks and the second set of limiting blocks have guide slopes and limiting surfaces. The guide slopes are used to contact the elastic band and squeeze the elastic band inward so that the area of the elastic band gradually decreases.
[0017] The limiting surface is located on the side of the glove stack bearing platform relative to the guide slope. The limiting surface is used to block the rubber band, thereby detaching the rubber band from the rubber band support rod.
[0018] Furthermore, the number of the first set of limiting blocks and the second set of limiting blocks are both at least two, and at least two of the first set of limiting blocks / second set of limiting blocks are distributed at least at the positions of the two opposite sides of the stretched rubber band, blocking at least two opposite sides of the stretched rubber band.
[0019] Furthermore, there are four of each of the first and second groups of limiting blocks, and the four first / second group limiting blocks are distributed at the four corners of the stretched rubber band.
[0020] Furthermore, the limiting surfaces of the first set of limiting blocks and / or the second set of limiting blocks are provided with groove structures.
[0021] Furthermore, a mounting frame is provided between the elastic band support structure and the glove stack support platform, and the first set of limiting blocks, the touch sensor, and the second set of limiting blocks are mounted on the mounting frame.
[0022] Furthermore, the plane where the touch sensor is located is closer to the elastic band support structure than the plane where the first set of limiting blocks is located, and the plane where the second set of limiting blocks is located is closer to the elastic band support structure than the plane where the touch sensor is located.
[0023] Furthermore, the elastic band support structure remains fixed, the mounting bracket is installed on the glove stack support platform, and the mounting bracket and the glove stack support platform move relative to the elastic band support structure as a whole.
[0024] Alternatively, the mounting bracket and the glove stack support platform can be fixed in place, while the elastic band support structure can move relative to the glove stack support platform.
[0025] Furthermore, the glove stack carrying platform includes a carrying conveyor belt, which is connected to a conveyor belt translation mechanism that controls the carrying conveyor belt and the glove stack carrying platform to move closer to or further away from the elastic band support structure. The conveying direction of the carrying conveyor belt is perpendicular to the translation direction of the conveyor belt translation mechanism.
[0026] Furthermore, a glove base support plate is provided below the conveyor belt at the position of the elastic band on the stack of gloves. The glove base support plate is connected to a support plate telescopic device, which is used to control the glove base support plate to extend or retract from the side of the conveyor belt near the elastic band support structure.
[0027] Furthermore, a set of non-powered guide rollers is provided on the side of the conveyor belt near the elastic band support structure. The set of non-powered guide rollers are continuously distributed on the side of the conveyor belt near the elastic band support structure, except for the pallet telescopic device.
[0028] Furthermore, a power wheel is provided on the side of the conveyor belt near the rubber band support structure, and the power wheel is located before the first unpowered guide roller.
[0029] Furthermore, the rubber band support rod is provided with a protruding limiting ring, which is located between the end of the rubber band support rod and the stretched rubber band.
[0030] This utility model has the following beneficial effects:
[0031] This invention incorporates a touch sensor before the first set of limiting blocks and the elastic band support structure to detect whether the elastic band is fully supported on the four elastic band support rods. When the touch sensor detects that the elastic band is not fully supported on the four elastic band support rods, the clamping process is stopped to prevent clamping failure. This also prevents the stack of gloves from being disturbed, thus improving the success rate of clamping stacked gloves. Attached Figure Description

[0036] 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.
[0037] This utility model embodiment provides a device for securing stacked gloves with elastic bands, such as... Figure 1-4 As shown, the device includes an elastic band support structure 1 and a glove stack support platform 3 that carries stacks of gloves 2. The elastic band support structure 1 and the glove stack support platform 3 have relative movements that bring them closer together or further apart. This relative movement can be such that one of the elastic band support structure 1 and the glove stack support platform 3 remains stationary while the other moves, or both can move.
[0038] The elastic band support structure 1 includes four elastic band support rods 4 for receiving and expanding the elastic band 7. The four elastic band support rods 4 face one side of the glove stack support platform 3. The elastic band support rods 4 can be controlled by support rod telescopic cylinders 5, which are located at the telescopic ends of the cylinders 5, which are positioned at the four corners of the support rod mounting frame 6. Driven by the four support rod telescopic cylinders 5, the four elastic band support rods 4 either converge towards the center to receive the elastic band or expand outwards to expand the elastic band 7.
[0039] A first set of limiting blocks 8 is provided between the rubber band support structure 1 and the glove stack support platform 3. The first set of limiting blocks 8 is used to make the rubber band 7 separate from the rubber band support rod 4 and tighten the stack of gloves 2 after the root of the stack of gloves 2 is put into the open rubber band 7.
[0040] A touch sensor 9 is provided between the first set of limiting blocks 8 and the rubber band support structure 1 to detect whether the rubber band 7 is fully supported on the four rubber band support rods 4.
[0041] When the rubber band 7 is not fully supported on the four rubber band support rods 4, the rubber band cannot be put on the stack of gloves 2, resulting in the failure of the glove stacking. Even worse, the rubber band that is not fully supported on the four rubber band support rods 4 may touch the stack of gloves 2 (for example, when the rubber band 7 is put on three rubber band support rods 4), causing the position of the stack of gloves 2 to change, making it impossible to perform subsequent hooping.
[0042] To address the aforementioned issues, this invention incorporates a touch sensor 9 positioned before the first set of limiting blocks 8 and the elastic band support structure 1. This sensor detects whether the elastic band 7 is fully supported on the four elastic band support rods 4. Because the touch sensor 9 is closer to the elastic band support structure 1, when the elastic band is being fitted, it is detected by the touch sensor 9 before reaching the first set of limiting blocks 8. When the touch sensor 9 detects that the elastic band 7 is not fully supported on the four elastic band support rods 4, it stops moving towards the first set of limiting blocks 8, thus preventing fitting failure and avoiding triggering the stack of gloves, which could prevent subsequent fitting. This improves the success rate of fitting stacked gloves.
[0043] The first set of limiting blocks 8 has a guide ramp 12 and a limiting surface 13. The guide ramp 12 is used to contact the rubber band 7, squeezing the rubber band 7 inward so that the area of the rubber band 7 gradually decreases. Specifically, as the rubber band support structure 1 and the glove stack bearing platform 3 approach each other, the rubber band contacts the guide ramp 12. Under the action of the guide ramp 12, the rubber band 7 is elastically squeezed, causing the area of the rubber band to gradually decrease. After the rubber band separates from the first set of limiting blocks 8, the rubber band returns to its initial area of expansion.
[0044] The limiting surface 13 is located on the side of the glove stack support platform 3 relative to the guide slope 12. The limiting surface 13 is used to block the elastic band 7, thereby detaching the elastic band 7 from the elastic band support rod 4. Specifically, the limiting surface 13 can be a surface perpendicular to the elastic band support structure 1 or the glove stack support platform 3. As the elastic band support structure 1 and the glove stack support platform 3 move away from each other, the limiting surface 13 blocks the elastic band 7, detaching the elastic band 7 from the elastic band support rod 4. After detachment, the elastic band, under the action of elasticity, tightens the stack of gloves 2.
[0045] In one example, the touch sensor 9 includes a trigger spring 10 for contacting the extended rubber band. When the rubber band is fully extended, the extended rubber band contacts the trigger spring 10, triggering the touch sensor 9 and thus providing a judgment.
[0046] The number of touch sensors 9 is at least two, and the at least two touch sensors are distributed at least at the positions of the two opposite sides of the stretched rubber band 7 to detect at least the two opposite sides of the stretched rubber band 7.
[0047] When the glove is fully stretched, that is, stretched into a rectangle (or square), its two opposite sides are stretched open; conversely, when the glove is not fully stretched, that is, not stretched into a rectangle (or square), at least one of its two opposite sides is not stretched open. Therefore, the two opposite sides of the stretched elastic band 7 can be checked to determine whether the glove is fully stretched.
[0048] Therefore, at least two touch sensors 9 are required to detect the two opposite sides of the stretched rubber band 7. Of course, more touch sensors 9 can be set, either on other sides or on the opposite sides, thus using multiple touch sensors 9 to detect one side.
[0049] Specifically, there can be four touch sensors 9, distributed at the four corners of the extended elastic band 7. The four touch sensors 9 can detect each of the four sides of the extended elastic band 7. Alternatively, two touch sensors 9 can be placed on each of two opposite sides to detect those two opposite sides. Or, all four touch sensors 9 can detect three sides respectively.
[0050] As an improvement of this utility model embodiment, a second set of limiting blocks 11 is provided between the touch sensor 9 and the rubber band support structure 1. The second set of limiting blocks 11 is used to cause the rubber band 7 to detach from the rubber band support 4 and fall down when the touch sensor 9 detects that the rubber band 7 is not fully supported on the four rubber band support rods 4.
[0051] Similar to the first set of limiting blocks 8, the second set of limiting blocks 11 also has similar guide ramps 14 and limiting surfaces 15. When the touch sensor 9 detects that the elastic band 7 is not fully supported on the four elastic band support rods 4, the elastic band support structure 1 and the glove stack support platform 3 no longer approach each other, but move away from each other. Since the second set of limiting blocks 11 is closer to the elastic band support structure 1 than the touch sensor 9, the limiting surface 15 blocks the elastic band 7 during the moving away process, causing the elastic band 7 to detach from the elastic band support rods 4, and the detached elastic band falls down.
[0052] This utility model is provided with a second set of limiting blocks 11. When it is detected that the rubber band 7 is not fully supported on the four rubber band support rods 4, the second set of limiting blocks 11 will automatically remove the rubber band from the rubber band support rods 4, so as to facilitate the subsequent reception of new rubber bands by the rubber band support rods 4.
[0053] In this utility model, there are at least two first set of limiting blocks 8 and at least two second set of limiting blocks 11. At least two first set of limiting blocks 8 / second set of limiting blocks 11 are distributed at least at the positions of two opposite sides of the stretched rubber band 7, blocking at least two opposite sides of the stretched rubber band 7, thereby detaching the rubber band 7 from the rubber band support rod 4.
[0054] Specifically, the number of the first set of limiting blocks 8 and the second set of limiting blocks 11 can both be four, with the four first set of limiting blocks 8 / second set of limiting blocks 11 distributed at the four corners of the stretched rubber band 7.
[0055] The limiting surfaces 13 and 15 of the first set of limiting blocks 8 and / or the second set of limiting blocks 11 are provided with groove structures 16. The length direction of the groove structure 16 is consistent with the circumferential direction of the stretched rubber band 7. The groove structure 16 is used to provide a certain resistance when the limiting surfaces 13 and 15 block the rubber band 7, so as to prevent the blocking failure.
[0056] For ease of installation, a mounting frame 17 is provided between the first set of limit blocks 8, the touch sensor 9, the second set of limit blocks 11, the elastic band support structure 1, and the glove stack bearing platform 3. The first set of limit blocks 8, the touch sensor 9, and the second set of limit blocks 11 are mounted on the mounting frame 17.
[0057] Specifically, the first set of limiting blocks 8, the touch sensor 9, and the second set of limiting blocks 11 are each installed on a plane. The plane where the touch sensor 9 is located is closer to the elastic band support structure 1 than the plane where the first set of limiting blocks 8 is located, and the plane where the second set of limiting blocks 11 is located is closer to the elastic band support structure 1 than the plane where the touch sensor 9 is located.
[0058] In this utility model, the elastic band support structure 1 can be fixed, and the mounting frame 17 can be installed on the glove stack support platform 3. The mounting frame 17 and the glove stack support platform 3 can move relative to the elastic band support structure 1.
[0059] Alternatively, the mounting bracket 17 and the glove stack support platform 3 can be fixed, while the elastic band support structure 1 moves relative to the glove stack support platform 3.
[0060] In one example, the glove stack carrying platform 3 includes a carrying conveyor belt 18, and a mounting frame 17 is mounted on a support of the carrying conveyor belt 18. The carrying conveyor belt 18 is connected to a conveyor belt translation mechanism that controls the carrying conveyor belt 18 and the mounting frame 17 to move closer to or further away from the elastic band support structure 1. The conveying direction of the carrying conveyor belt 18 is perpendicular to the translation direction of the conveyor belt translation mechanism.
[0061] For example, the carrying conveyor belt 18 and the mounting frame 17 are mounted as a whole on the conveyor belt slide rail 19, and the conveyor belt translation mechanism controls the carrying conveyor belt 18 and the mounting frame 17 to translate as a whole along the conveyor belt slide rail 19.
[0062] Below the conveyor belt 18, at the position of the elastic band on the stack of gloves 2, there is a glove root support plate 20. The glove root support plate 20 is connected to a support plate telescopic device 21. The support plate telescopic device 21 is used to control the glove root support plate 20 to extend or retract from the side of the conveyor belt 18 near the elastic band support structure 1.
[0063] When the stack of gloves 2 is secured with elastic bands, the glove base support plate 20 extends to support the base of the stack of gloves 2. During the securing of the stack of gloves 2, the elastic bands secure the stack of gloves 2 together with the glove base support plate 20. Afterward, the glove base support plate 20 retracts and is pulled out from the stack of gloves 2 after securing.
[0064] This utility model does not limit the specific structural form of the conveyor belt translation mechanism and the pallet telescopic device 21. They can be various power components that can achieve linear displacement, such as cylinders, linear motors, and lead screw motors.
[0065] A set of non-powered guide rollers 22 is provided on the side of the conveyor belt 18 near the elastic band support structure 1. The set of non-powered guide rollers 22 is continuously distributed on the side of the conveyor belt 18 near the elastic band support structure 1, except for the pallet telescopic device 20. The non-powered guide rollers 22 are used to guide the stack of gloves 2 when the conveyor belt 18 is conveying them.
[0066] Stacks of gloves 2 are conveyed to the carrier conveyor belt 18 by various preceding mechanisms, such as conveyor belts. At the junction where stacks of gloves 2 move from the preceding mechanisms to the carrier conveyor belt 18, it is easy for the palm part of the stacks of gloves 2 to have been conveyed to the carrier conveyor belt 18, but the base part cannot be conveyed to the carrier conveyor belt 18. This causes the stacks of gloves 2 to fail to reach the carrier conveyor belt 18 smoothly, or causes the stacks of gloves 2 to be skewed, making it difficult to achieve subsequent clamping.
[0067] To solve the above problems, this utility model provides a power wheel 23 on the side of the conveyor belt 18 near the elastic band support structure 1, with the power wheel 23 located before the first unpowered guide roller 22. The power wheel applies power to the base of the stack of gloves 2, allowing the stack of gloves 2 to smoothly reach the conveyor belt 18.
[0068] Various structures that increase friction can be provided on the circumferential surface of the drive wheel 23, such as adding raised or recessed structures or textures, or adding materials with high friction such as rubber or silicone.
[0069] The power of the drive wheel 23 can come from the transmission power of the conveyor belt 18 itself, for example, the drive wheel 23 is connected to the drive motor of the conveyor belt.
[0070] When the guide slopes 12 and 14 of the first set of limiting blocks 8 and the second set of limiting blocks 11 press the elastic band 7 inward, the elastic band 7 is subjected to a force on the elastic band support structure 1, and the elastic band 7 tends to move along the elastic band support rod 4 towards the elastic band support structure 1. To this end, the present invention provides a protruding limiting ring 24 on the elastic band support rod 4. The limiting ring 24 is located between the end of the elastic band support rod 4 and the spread elastic band 7 to prevent the elastic band 7 from moving towards the elastic band support structure 1.
[0071] 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.
