Description

Technical Field

[0001] This utility model relates to the field of glove production technology, specifically a glove sorting mechanism. Background Technology

[0002] Gloves are widely used in daily life and production, especially latex gloves and nitrile gloves. In the medical and health field, latex gloves are used as protective equipment for surgery, patient examination, dental treatment, intravenous infusion, etc. In the industrial manufacturing field, latex gloves are used to protect hands from chemicals, oil, and sharp parts. In the daily cleaning and sanitation field, latex gloves can effectively isolate the skin from the chemicals in cleaning agents. In the food processing field, latex gloves can prevent human hands from coming into contact with food and prevent food contamination.

[0003] In production practice, finished gloves are often stacked together and require manual counting and sorting to align the wrists and fingertips for easier packaging and cleaning. However, manual counting and sorting is inefficient and difficult to keep up with high-speed production lines (especially modern lines that produce hundreds of gloves per minute), becoming a bottleneck for increasing overall production capacity. Manual counting is also time-consuming, labor-intensive, and leads to rising labor costs. Furthermore, manual counting has a high error rate, is prone to fatigue errors, resulting in inaccurate quantities per pack / box, causing customer complaints and commercial disputes, and hindering refined factory management.

[0004] In existing technologies, some intelligent recognition algorithms are used for counting and sorting. However, given the characteristics of the glove material, which is not only soft and thin but also easy to fold and stick, if it cannot be laid flat on the conveyor belt manually, the gloves placed on the conveyor belt are prone to folding and forming irregular shapes. This results in low accuracy of visual inspection and deep learning recognition, which cannot meet the requirements. In addition, the cost of intelligent visual recognition and inspection equipment is high, which prevents large-scale market application. Utility Model Content

[0005] This utility model discloses a glove sorting mechanism, which solves the technical problems of high time-consuming, labor-intensive, and costly manual counting and sorting, and low accuracy and low cost of visual inspection and intelligent recognition in the prior art. It features a reasonable structure, high sorting efficiency and accuracy, and helps reduce costs. The technical solution adopted is as follows:

[0006] A glove sorting mechanism includes a sorting unit, a first drive unit, and a material handling assembly. The sorting unit can rotate around a central axis under the action of the first drive unit. When the sorting unit rotates through a set position, the movable end of the sorting unit can move up and down to pick up gloves. The sorting unit is designed such that the movable end of the sorting unit moves up and down at least twice in one stroke to pick up gloves.

[0007] The material handling assembly is designed to remove gloves picked up by the sorting unit and to ensure that the sorting unit picks up only a single glove.

[0008] Based on the above technical solution, the material handling component includes a material handling channel fixed above the material tray. The material handling channel is designed to be funnel-shaped and gradually narrows from the inlet side to the outlet side. When the sorting unit picks up multiple gloves and allows multiple gloves to pass through the material handling channel, the excess gloves are scraped off and a single glove is allowed to pass through.

[0009] Based on the above technical solution, the material handling channel has a U-shaped cross section that slopes upward from the inlet side to the outlet side, and is adapted to the movement trajectory of the end of the sorting unit.

[0010] Based on the above technical solution, the material handling channel extends along an arc and is adapted to the movement trajectory of the end of the sorting unit.

[0011] Based on the above technical solution, there are multiple material handling components, and the number of times the sorting unit picks up gloves by moving up and down is the same. The material handling components are arranged in front of the position where the sorting unit moves up and down. When the sorting unit picks up multiple gloves and allows multiple gloves to pass through the material handling channel, the material handling components can scrape off the excess gloves and allow a single glove to pass through.

[0012] Based on the above technical solution, the sorting unit includes a third drive unit and a movable end. The third drive unit is used to drive the movable end to move up and down. The movable end includes an air cylinder and an air passage pipe. The air cylinder includes a hollow cavity and has an air nozzle on the end face facing the glove. The air passage pipe is connected to the central control cavity and can form a negative pressure in the hollow cavity. When the sorting unit rotates past the material tray and the third drive unit drives the air cylinder downward to contact the glove, the air nozzle can pick up the glove.

[0013] Based on the above technical solution, the air nozzle is in the shape of an "I" and is made of an elastic material, such as rubber.

[0014] Based on the above technical solution, it also includes a material tray and a sorting tray. The material tray is used to hold gloves. There are multiple sorting units that are evenly arranged circumferentially on the sorting tray. The sorting tray is located above the material tray and can rotate relative to the material tray under the action of the first driving unit so that the moving end of the sorting unit can pick up the gloves in the material tray.

[0015] Based on the above technical solution, a second driving unit is also included. The sorting tray and the material tray are eccentrically arranged. The first driving unit drives the sorting tray to rotate in the forward direction, and the second driving unit drives the material tray to rotate in the reverse direction. The rotational angular velocity of the material tray is less than that of the sorting tray.

[0016] Based on the above technical solution, it also includes a fourth drive unit and a paddle plate. The end of the paddle plate is located near the material tray and can swing under the action of the fourth drive unit to move the gloves toward the sorting unit.

[0017] Beneficial effects

[0018] This invention features a rationally designed sorting unit that moves up and down to pick up gloves. The sorting unit performs at least two up-and-down movements per stroke to pick up gloves from the tray. This avoids the chance of the sorting unit "empty-sucking" in a single stroke, even when there are few gloves in the tray, thus improving production efficiency and reducing energy consumption. Simultaneously, it has high tolerance for the feeding frequency of the upstream glove conveying unit, ensuring continuous and stable sorting operations. Furthermore, the negative pressure method used at the moving end of the sorting unit to adsorb gloves minimizes damage and ensures a cleaner working process. Additionally, the air nozzle is made of elastic material, allowing for good contact with the flexible gloves, preventing wear and tear, and providing excellent negative pressure adsorption.

[0019] This invention also includes a material handling component, wherein the material handling channel is designed in a funnel shape, with its exit side allowing only one glove to pass through at a time. This allows excess gloves to be scraped off when the sorting unit moves up and down to pick up two or more gloves, facilitating the subsequent gripping unit to pick up and organize the gloves, thus promoting continuous and stable production. Furthermore, the material handling channel slopes upwards from the inlet to the outlet, matching the movement trajectory of the end of the sorting unit. This guides the gloves picked up by the sorting unit smoothly into the material handling channel, preventing them from getting caught and worn. Additionally, as the channel narrows during its advance, the gloves are brought together, facilitating the scraping off of excess gloves at the outlet side. This also helps to flatten the gloves to a certain extent, ensuring they remain spread out and non-sticky when dropped, facilitating subsequent production activities. Furthermore, the number of material handling channels is the same as the number of times the sorting unit moves up and down to pick up gloves, and the material handling channels are located in front of the position where the sorting unit moves up and down, so as to scrape off excess gloves after each time the sorting unit picks up gloves and allow a single glove to pass through. This ensures that the sorting unit always picks up a glove in one stroke, further ensuring production stability and continuity. The design is ingenious.

[0020] In this invention, the material tray and the sorting tray are eccentrically arranged and rotate in opposite directions. This allows the sorting unit to pick up the gloves in the material tray relatively evenly. Moreover, with the rotation speed difference between the material tray and the sorting tray set, it is beneficial to reduce the rotation speed of the sorting tray and avoid the gloves "drifting" during the sorting process, thus preventing them from disrupting the subsequent production rhythm.

[0032] like Figures 1-5 The glove sorting mechanism shown includes a sorting unit 5, a first drive unit 4, and a material handling assembly 6.

[0033] like Figure 3 As shown, the sorting unit 6 can rotate around a central axis under the action of the first drive unit 5, thus completing the picking and transfer of gloves.

[0034] Specifically, it also includes a frame 1, a material tray 2, a sorting tray 3, and a second drive unit 11;

[0035] In this embodiment, the frame 1 includes an aluminum profile frame structure, which is convenient for processing and manufacturing.

[0036] like Figure 3 As shown, the material tray 2 is rotatably mounted on the frame 1, and a thrust bearing is sleeved at its rotatable connection point for holding gloves, such as latex gloves, rubber gloves, etc.; the second drive unit 11 includes a second motor fixed on the frame 1 through a motor base, which can transmit rotational motion to the material tray 2, causing the material tray 2 to rotate.

[0037] like Figures 3-5As shown, the sorting tray 3 is positioned above the material tray 2, and is eccentrically positioned relative to the material tray 2. A central shaft is located at the center of the sorting tray 3, and the central shaft is rotatably connected to the frame 1. A bearing is fitted at the rotatable connection point. The first drive unit 4 includes a first motor fixed to the frame 1 via a motor mount. The first motor transmits rotational motion to the sorting tray 3. In this embodiment, the first drive unit 4 drives the sorting tray 3 to rotate in the forward direction, and the second drive unit drives the material tray 2 to rotate in the reverse direction. The rotational speed of the material tray 2 is less than that of the sorting tray 3, facilitating the uniform picking of gloves from the material tray 2. In other embodiments of this invention, a first conveying unit may also be provided. The first conveying unit is positioned above the material tray 2 to convey gloves into the material tray 2, thus replacing manual feeding.

[0038] like Figures 3-5 As shown, the sorting tray 3 includes several sorting units 5 arranged circumferentially. Each sorting unit 5 can move up and down to pick up gloves from the tray; in this embodiment, as... Figure 1 As shown, the sorting unit 5 includes a third drive unit 51 and a movable end. The third drive unit 51 is fixed on the sorting tray 3 and includes any one of a cylinder, hydraulic cylinder, or electric push rod. In this embodiment, the third drive unit 51 includes a cylinder. The cylinder body is detachably connected to the top surface of the sorting tray 3 downwards for easy replacement and maintenance. The movable end includes an air cylinder 52 and an air passage pipe. The piston rod of the cylinder passes through the sorting tray 3 and is connected to the air cylinder 52. The air cylinder 52 includes a hollow cavity and an air nozzle is provided on the bottom end face facing the material tray 2. The hollow cavity is connected to the air nozzle and the air passage pipe respectively. The bottom end face and the side face of the air cylinder 52 are smoothly transitioned to avoid sharp corners from damaging the gloves. In this embodiment, the air nozzle is made of rubber, which has good elasticity. On the one hand, it can buffer when in contact with the gloves, making flexible contact with the gloves, and on the other hand, it avoids rigid materials from damaging the gloves.

[0039] When the sorting unit 5 rotates to the set position above the material tray 2, the third drive unit 51 drives the air cylinder 52 downward to contact the gloves, and at the same time, a vacuum is drawn into the cavity of the air cylinder 52 through the external air passage to adsorb and pick up the gloves. The sorting unit 5 is designed to perform at least two up-and-down movements to pick up gloves in one stroke. In this embodiment, the sorting unit 5 performs two up-and-down movements to pick up gloves in one stroke. Thus, even if the gloves are not stacked evenly in the material tray 2 and there are cases where no gloves are picked up, the design of the sorting unit 5 performing multiple up-and-down movements in this application can greatly increase the probability that the sorting unit 5 will pick up at least one glove in one stroke.

[0040] The material handling component 6 is designed to reject gloves picked up by the sorting unit 5, ensuring that the sorting unit picks up only a single glove. In this embodiment, for example... Figure 2 As shown, the material handling assembly 6 includes a material handling channel fixed above the material tray 2. In this embodiment, the opening cross-section of the material handling channel is U-shaped, as shown below. Figures 3-5As shown, the feeding channel is designed to be funnel-shaped, gradually narrowing from the inlet to the outlet. When the sorting unit 5 picks up multiple gloves and allows them to pass through the feeding channel, the narrower outlet can scrape off excess gloves and allow a single glove to pass through. In addition, the feeding assembly is connected to the frame 1 and can swing up and down and left and right, making it adaptable and easy to assemble.

[0041] like Figure 2 and 3 As shown, the material handling channel slopes upwards from the inlet side to the outlet side, and is adapted to the movement trajectory of the end of the sorting unit 5. This allows the picking unit 5 to quickly move the gloves into the material handling channel after picking them up. In this embodiment, the bottom surface of the outlet side of the material handling channel extends outwards and is close to the inner bottom surface of the tray 2, so that the gloves can quickly enter the material handling channel after the sorting unit 5 picks them up. At the same time, the process of the sorting unit 5 carrying the gloves smoothly through the material handling channel can effectively straighten the gloves, reduce folding, and ensure that the gloves come out of the material handling channel with a roughly uniform shape.

[0042] In other embodiments of this application, the axis of the material handling channel may extend along an arc and be adapted to the movement trajectory of the end of the sorting unit to avoid the material handling channel scraping the surface of the glove.

[0043] In this embodiment, the sorting unit 5 is designed to pick up gloves from the tray 2 by at least two up-and-down movements. This greatly increases the probability that the sorting unit 5 will pick up gloves in one stroke. The number of material handling channels is the same as the number of up-and-down movements of the sorting unit 5, and the two material handling channels are located in front of the up-and-down displacement position of the sorting unit 5 in a one-to-one correspondence. This allows the sorting unit 5 to scrape off excess gloves after each glove is picked up and allows a single glove to pass through. In this way, it can also be ensured that the sorting unit 5 picks up at most one glove in one stroke. This is a clever design.

[0044] like Figures 3-5 As shown, it also includes a fourth drive unit 7 and a paddle plate 8. As shown in the figure, there are multiple paddle plates 8 arranged in a fan shape. The fourth drive unit 7 includes a fourth motor fixed on the frame 1. The fourth motor can transmit rotational motion to the head end of the paddle plate 8. The end of the paddle plate 8 is located near the material tray 2 and can swing under the action of the fourth motor to paddle the gloves to the sorting unit 5.

[0045] like Figure 3 As shown, it also includes a material support platform 9, which is located outside the material tray 2 and has a material drop opening 91. When the sorting unit 5 picks up the gloves and rotates them outside the material tray 2, the material support platform 9 can receive the gloves that fall in the event of a malfunction. The material support platform 9 is also fixed with a vertical plate to isolate the material drop opening 91 from the material tray 2, so as to prevent the gloves from falling into the gap in case of an accident, which helps to improve production safety.

[0046] In this embodiment, a clamping unit 10 is provided at a predetermined position below the material discharge port 91. The clamping unit 10 is a prior art technology, such as... Figure 4 As shown, the gripping unit 10 is used to grip the gloves and peel them off from the air nozzle of the sorting unit 5. In this embodiment, the vertical height of the gripping unit 10 is designed such that when the sorting unit 5 picks up the gloves at the wrist or fingertips, the gloves hang down to a lower position and can be gripped by the gripping unit. This ensures that the gripping unit 10 can lay the gloves flat after gripping them, which is convenient for subsequent production. When the sorting unit 5 picks up the gloves at the middle position, the gloves are roughly folded and hang down to a higher position. The gloves do not come into contact with the gripping unit 10, thus avoiding the situation where the gripping unit 10 cannot lay the gloves flat after gripping them.

[0047] Work process

[0048] First, under the action of the first drive unit 4 and the second drive unit 11, the sorting disk 3 rotates relative to the material disk 2, that is, the sorting disk 3 rotates in the forward direction and the material disk 2 rotates in the reverse direction at a smaller speed.

[0049] Subsequently, when the sorting unit 5 rotates above the material tray 2, the hollow cavity inside the air cylinder remains in a vacuum state. The sorting unit 5 moves downward for the first time and then upward to pick up the gloves in the material tray 2. A material handling channel is located in front of the position where the sorting unit 5 moves up and down for the first time. After that, regardless of whether the sorting unit 5 picks up gloves, picks up one or more gloves, the sorting unit 5 passes through the material handling channel. When picking up multiple gloves, the outlet of the material handling channel scrapes off the excess gloves and allows a single glove to pass through.

[0050] Afterwards, the sorting unit 5 moves downwards for the second time and then upwards to pick up the gloves from the tray 2 again. In this way, even if the sorting unit fails to pick up the gloves during its first up-and-down movement, it can pick up the gloves again, ensuring that the sorting unit picks up at least one glove in one stroke.

[0051] Subsequently, another material handling channel is located in front of the second vertical displacement position of sorting unit 5. When the gloves picked up by sorting unit 5 pass through the material handling channel, excess gloves can be scraped off at the outlet of the material handling channel, allowing a single glove to pass through. In addition, during the process of the gloves passing through the material handling channel, due to the funnel-shaped design of the material handling channel, the gloves can be straightened, reducing the occurrence of glove folds, and gloves that are glued to it can also be peeled off. Among them, an identification unit (not shown) is also provided on the outlet side of the material handling channel through which the gloves last pass. The identification unit includes a sensor for identifying whether the end of the sorting unit has picked up a glove, and can send a signal to the downstream gripping unit 10 that grips the glove. The sensor is existing technology and will not be described in detail.

[0052] Afterwards, the sorting unit 5 rotates the picked-up gloves outside the material tray 2 and completes the unloading. Specifically, when the sorting unit 5 rotates above the unloading port 91, the sensor sends a signal to the gripping unit 10, and the gripping unit 10 is activated. If the sorting unit 5 picks up the gloves at the wrist or fingertips, the gloves hang down to a lower position and can be gripped by the gripping unit 10. This ensures that the gripping unit 10 can lay the gloves flat after gripping them, which is convenient for subsequent production. However, if the sorting unit 5 picks up the gloves at the middle position, the gloves are roughly folded and hang down to a higher position. The gloves do not come into contact with the gripping unit 10, thus avoiding the situation where the gripping unit 10 cannot lay the gloves flat after gripping them.

[0053] Afterwards, the sorting unit 5 continues to rotate after passing through the discharge port 91. At this time, the vacuuming of the hollow cavity inside the air cylinder is stopped, so that the gloves that were not picked up by the clamping unit 10 fall into the material support table 9 or the material tray 2.

[0054] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
