Description

Technical Field

[0001] This utility model relates to the field of glove production, and in particular to an automatic glove turning machine. 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] During the glove flipping process, the gloves are first placed on the flipping mold, and then flipped onto the material handling mold using a flipping rod or flipping frame. Finally, the gloves are removed from the material handling mold, stacked, and then conveyed to the elastic banding mechanism for glove stacking and bundling.

[0004] Because the gloves are flexible, they may not fit correctly onto the flipping mold, requiring removal to prevent interference with subsequent glove flipping. Current technology typically involves manual removal, which is not only inefficient and lacks automation but also poses safety hazards. Utility Model Content

[0046] 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.

[0047] This utility model embodiment provides an automatic glove turning machine, such as... Figure 1-13 As shown, it includes a glove opening mechanism 100, a flipping mechanism 200, a feeding mechanism 300, and a bundling mechanism 400.

[0048] The glove-opening mechanism 100 is used to open the glove's base and fit it onto the flipping mechanism 200. The flipping mechanism 200 flips the glove onto the unloading mechanism 300, which unloads the flipped gloves into a stack. The bundling mechanism 400 bundles the stacked gloves. In some embodiments, a glove-feeding mechanism is provided before the glove-opening mechanism 100 to feed the gloves and open the glove's base, allowing the glove-opening mechanism 100 to extend into the glove's base and open it. The glove-feeding mechanism is a common structure in the prior art and will not be described in detail in this invention.

[0049] The flipping mechanism 200 includes a horizontally arranged flipping hand mold 1 and an openable waste removal gripper 2. The flipping hand mold 1 is equipped with a glove detector 3 to detect whether the gloves on the flipping hand mold 1 need to be removed. The flipping hand mold 1 is provided with a raised structure 4.

[0050] The waste removal gripper 2 cooperates with the protruding structure 4. The waste removal gripper 2 is connected to a waste removal drive mechanism that controls the waste removal gripper 2 to move closer to or away from the protruding structure 4. The waste removal gripper 2 is also connected to a gripper drive mechanism 5 that controls the opening and closing of the waste removal gripper 2.

[0051] In use, the glove opening mechanism 100 opens the glove at the base and places it onto the flipped hand mold 1. The protruding structure 4 causes the glove on the flipped hand mold 1 to protrude at that position. A glove detector checks the glove on the flipped hand mold. If the glove is not properly fitted onto the flipped hand mold 1, or if the glove is damaged, it needs to be removed. At this time, the waste removal drive mechanism controls the waste removal gripper 2 to move to the protruding structure 4. Controlled by the gripper drive mechanism 5, the waste removal gripper 2 grasps the protruding glove at the protruding structure 4 and then leaves the flipped hand mold 1, thus removing waste during glove flipping.

[0052] This invention enables automatic waste removal during glove turning, improves the automation process of glove turning, reduces manual intervention, increases production efficiency, and has a simple structure and is easy to operate.

[0053] The aforementioned glove detector can be a photoelectric sensor or a camera. When it is a photoelectric sensor, the detection position of the photoelectric sensor is aligned with the position of the heel of the glove on the flipped hand mold 1.

[0054] Once the glove is correctly placed on the flipped hand mold, the position of the glove's base is fixed. Therefore, the position of the glove's base can be detected by a photoelectric sensor. When a glove is detected at that position, it is considered that the glove is correctly placed on the flipped hand mold.

[0055] When a camera is used, it is connected to a data processing device. The camera captures images of the gloves, and image detection methods are used to accurately determine whether the gloves are correctly fitted onto the flipped hand mold, and to detect defects such as tears. The image detection method can be any method disclosed in existing technology, such as methods based on neural networks.

[0056] In one example, the flipped hand mold 1 includes a finger portion 6 and a palm portion 7. The raised structure 4 can be set on one of the five fingers of the finger portion 6 or on the palm portion 7.

[0057] Preferably, the protrusion 4 can be placed on the middle finger, which is located at the front center of the palm portion 7.

[0058] As an improvement to this embodiment of the present invention, the aforementioned glove opening mechanism 100 includes two glove opening plates 8. Each glove opening plate 8 is connected to an opening drive mechanism that controls the opening and closing of the two glove opening plates 8. The two glove opening plates 8 are used to open the glove after it is inserted into the base of the glove, allowing it to be fitted onto the flipping hand mold 1. The opening drive mechanism is not shown in the figure and can be any existing power mechanism capable of performing this function, such as a hydraulic cylinder, pneumatic cylinder, or motor.

[0059] Each glove opening plate 8 has a fixed glove clamping plate 9 on its outer side. When the glove opening plate 8 is opened, it cooperates with the glove pressing plate 9 to clamp the glove and prevent the glove from coming loose when it is put on the flipped hand mold 1.

[0060] The aforementioned glove support plate 8 and waste removal gripper 2 are disposed on the substrate 10. The waste removal driving mechanism includes a first driving unit 11 that drives the substrate 10 to move in a direction perpendicular to the plane where the flipped hand mold 1 is located, and a second driving unit that drives the waste removal gripper 2 to move in the direction where the fingers of the flipped hand mold 1 are located.

[0061] The second drive unit also serves as the overall moving mechanism for the glove support plate 8, used to slip the glove onto the flipping hand mold 1. The second drive unit is not shown in the figure and can be any existing power mechanism capable of performing this function, such as a hydraulic cylinder, pneumatic cylinder, or motor. The first drive unit 11 and the gripper drive mechanism 5 are preferably pneumatic cylinders, but other power mechanisms are also possible.

[0062] To facilitate gripping by the waste removal claws, the side of the protruding structure 4 away from the flipping hand mold 1 is a plate-shaped structure 13, which is gripped by the waste removal claws 2. The side of the protruding structure 4 connected to the flipping hand mold 1 has an arc-shaped transition structure 14, which serves as a transition and facilitates gripping by the waste removal claws 2.

[0063] The aforementioned waste removal gripper 2 can be perpendicular to the plane where the flipping hand mold 1 is located, or it can be parallel to the plane where the flipping hand mold 1 is located.

[0064] The five fingers of the flipped hand mold 1 are hollow, with a retractable guide core 12 inside each hollow finger. The guide core 12 is connected to a guide core extension / retraction drive mechanism 15. The front end of the guide core has a transition structure to facilitate the glove's fingers being slipped onto the fingers of the flipped hand mold 1. The guide core 12 is retractable; when the glove is slipped onto the flipped hand mold, the guide core 12 extends forward over the fingers of the flipped hand mold 1; when the glove is slipped on and the hand mold is flipped, the guide core 12 retracts into the fingers of the flipped hand mold 1. The guide core extension / retraction drive mechanism 15 is preferably a cylinder, but other power mechanisms are also possible. The guide core is made of polytetrafluoroethylene (PTFE), which has good self-lubricating properties.

[0065] As another improvement to this embodiment, the aforementioned feeding mechanism 300 is located below the flipping mechanism 200, and the flipping hand mold 1 is connected to a flipping hand mold driving mechanism 16 that controls the movement of the flipping hand mold 1 along a plane perpendicular to the flipping hand mold 1. When the gloves are correctly fitted onto the flipping hand mold 1, the flipping hand mold driving mechanism 16 moves it downwards to the feeding mechanism 300, cooperating with the feeding mechanism 300 to flip the hand mold. The flipping hand mold driving mechanism 16 is preferably a motor and its auxiliary structures (lead screw, etc.), but other power mechanisms are also possible.

[0066] The unloading mechanism includes a horizontally arranged material-picking hand mold 21, which is connected to a material-picking hand mold driving mechanism 22 that drives the material-picking hand mold 21 to move along the direction of the fingers of the material-picking hand mold 21.

[0067] The material handling hand mold drive mechanism 22 can be any drive component in the prior art that can realize the above-mentioned movement function. For example, it can be a drive method of motor and synchronous belt, or a drive method of cylinder, hydraulic cylinder, etc.

[0068] The material handling hand mold 21 is provided with an upper pressure plate 23 and a lower support plate 24 above and below, respectively. The upper pressure plate 23 and the lower support plate 24 are respectively connected to an upper pressure plate lifting mechanism 25 and a lower support plate lifting mechanism 26, which control the upper pressure plate 23 and the lower support plate 24 to move vertically.

[0069] The flipping hand mold 1 is equipped with a flipping spatula 17, which is located on the other side of the flipping hand mold 1 with the protruding structure 4. The front end of the flipping spatula 17 is inclined toward the flipping hand mold 1. The flipping spatula 17 is connected to a flipping drive mechanism 18 that controls the movement of the flipping spatula 17 along the direction of the fingers of the flipping hand mold 1. The flipping drive mechanism 18 is preferably a motor and its auxiliary structure (synchronous belt, etc.), but it can also be other power mechanisms.

[0070] In operation, the material-picking hand mold 21 moves towards the flipping hand mold 1 under the drive of the material-picking hand mold drive mechanism 22. The fingers of the material-picking hand mold 21 are inserted into the fingers of the flipping hand mold 1. The flipping shovel plate 17 moves towards the material-picking hand mold, inserts into the base of the glove, and continues to move, flipping the glove on the flipping hand mold 1 onto the material-picking hand mold 21. Then, the material-picking hand mold 21 moves away from the flipping hand mold. When the material-picking hand mold 21 moves between the upper pressure plate 23 and the lower support plate 24, the material-picking hand mold 21 temporarily stops. The upper pressure plate 23 and the lower support plate 24 move downward and upward respectively, clamping the upper and lower surfaces of the glove on the material-picking hand mold 21. Then, the material-picking hand mold 21 continues to move, and the glove is removed from the material-picking hand mold under the friction of the upper pressure plate 23 and the lower support plate 24, completing one glove unloading process.

[0071] Repeat the above steps to prepare the next glove. The newly prepared glove will be placed on top of the existing glove stack. Once the stack contains the set number of gloves, the stack will be flipped over.

[0072] In the process of removing gloves from the material handling mold and stacking them, the existing technology is prone to changes in the posture of the gloves, which can cause the stack of gloves to deviate from its proper position and adversely affect the subsequent bundling of the gloves, leading to bundling failure.

[0073] To solve the above problems, this utility model provides a glove stack sorting mechanism 27 in the space between the bottom of the material handling hand mold 21 and the top of the lower support plate 24. The glove stack sorting mechanism 27 includes two sorting clamps 28 arranged symmetrically. The sorting clamps 28 are connected to a clamp opening and closing mechanism 29 that controls the opening and closing of the two sorting clamps 28. The glove stack sorting mechanism 27 is connected to a sorting drive mechanism that controls the glove stack sorting mechanism 27 to move closer to or away from the glove stack.

[0074] Once the number of gloves in the glove stack on the current support plate 24 reaches the set number, the glove stack sorting mechanism 27 moves closer to the glove stack and sorts the glove stack's posture through two sorting clamps 28.

[0075] This invention uses a glove stack sorting mechanism to sort the flipped glove stacks, correct the posture deviation of the glove stacks, facilitate the subsequent bundling of the glove stacks, avoid bundling failures, and improve the efficiency of automated production.

[0076] Each of the aforementioned sorting clamps 28 is connected to a clamp shaft 30. Both the sorting clamps 28 and the clamp shaft 30 are vertically arranged. The clamp opening and closing mechanism 29 is connected to the clamp shaft 30 to control the opening and closing of the sorting clamps 28.

[0077] The two clamping plates 30 can be hinged together by a symmetrical linkage mechanism 31. The clamping plate opening and closing mechanism 29 is a linear power element, such as a cylinder. The center of the linkage mechanism 31 is connected to the linear power element, so that one linear power element can control the opening and closing of the two clamping plates 28 at the same time.

[0078] The material picking hand mold 21 can be set on the first set of horizontal slide rails 34, and the glove stacking mechanism 27 is set on the second set of slide rails 35 parallel to the first set of slide rails 34. The material picking hand mold 21 and the glove stacking mechanism 27 move along the first set of slide rails 33 and the second set of slide rails 34 respectively.

[0079] The aforementioned upper pressure plate 23 and lower support plate 24 can also be mounted on corresponding slide rails, and move vertically along the corresponding slide rails under the control of the upper pressure plate lifting mechanism 25 and the lower support plate lifting mechanism 26. The upper pressure plate lifting mechanism 25 and the lower support plate lifting mechanism 26 can be various power mechanisms such as motors and cylinders.

[0080] The aforementioned sorting drive mechanism and flipping drive mechanism 18 are the same drive mechanism. The glove stack sorting mechanism 27 also includes a first linkage mechanism 19 that connects or disconnects the glove stack sorting mechanism 27 and the flipping shovel plate 17.

[0081] The first linkage mechanism 19 includes a vertically arranged linkage rod 191, which is connected to a linkage rod drive mechanism 20 that controls the vertical movement of the linkage rod 191. The flipping shovel plate 17 is provided with a first linkage hole 192 that cooperates with the linkage rod 191.

[0082] During the normal glove flipping process, the linkage 191 descends, disengaging the glove stack sorting mechanism 7 from the flipping shovel 17. The flipping shovel 17, driven by the flipping drive mechanism 18, then flips the gloves. When the set number of flipped gloves is reached, the linkage 191 rises and inserts into the first linkage hole 192 of the flipping shovel 17. The flipping drive mechanism 18 then drives the flipping shovel 17 and the glove stack sorting mechanism 7 together to sort the gloves. At this point, glove flipping is paused; although the flipping shovel 17 moves, it does not flip the gloves.

[0083] This invention enables a single drive mechanism to control two parts: the flipping drive mechanism 18 controls both the movement of the flipping shovel plate 17 and the movement of the glove stacking mechanism 7, thereby reducing the number of power mechanisms and shrinking the size of the equipment.

[0084] The bundling mechanism 400 is located on one side of the unloading mechanism 300. The bundling mechanism 400 includes two horizontally arranged and parallel rubber band feeding shafts 41. The two rubber band feeding shafts 41 are provided with threads with the same direction of rotation and pitch. The two rubber band feeding shafts 41 are connected to a rotary drive mechanism 55, and the rotation direction and speed of the two rubber band feeding shafts are the same.

[0085] Around the rubber band feeding shaft 41, there is a rubber band opening mechanism 42 for opening the rubber bands on the rubber band feeding shaft 41 and a rubber band pusher plate 43 for pushing the rubber bands on the rubber band opening mechanism 42 onto the glove stack. The rubber band opening mechanism 42 is connected to an opening moving mechanism that controls the rubber band opening mechanism 42 to move closer to or away from the glove stack. The rubber band pusher plate 43 is connected to a pusher moving mechanism 44 that controls the rubber band pusher plate 43 to move closer to or away from the glove stack.

[0086] A conveyor belt 500 is provided on the other side of the feeding mechanism 300 opposite to the bundling mechanism 400.

[0087] In use, a rubber band is put onto the two rubber band feeding shafts 41 at once. Since the threads of the two rubber band feeding shafts 41 have the same direction and pitch, and the rotation direction and speed of the two rubber band feeding shafts 41 are the same, during the rotation of the two rubber band feeding shafts 41, each rubber band 45 will gradually enter into each thread under the action of the threads. Each rubber band 45 is spaced apart in the threads and is transmitted forward along the threads in sequence.

[0088] Then, the elastic band opening mechanism 42 opens the spaced individual elastic bands on the two elastic band feeding shafts 41, and moves them to the glove stack under the action of the opening moving mechanism, so that the elastic bands are located around the glove stack. Finally, under the action of the push plate moving mechanism 44, the elastic band push plate 43 pushes the opened elastic bands 46 onto the stack of gloves, realizing the glove bundling.

[0089] Finally, the glove stacking mechanism 27 holds the bundled gloves and transports them onto the conveyor belt 500, where they are carried away.

[0090] After a rubber band is put on the rubber band feeding shaft 41, it can be used for a relatively long time. When the rubber bands on the rubber band feeding shaft 41 are about to be used up, another rubber band can be put on the whole shaft.

[0091] This invention achieves automatic feeding of rubber bands through a rubber band feeding pivot, automating the stacking and bundling of gloves and improving production efficiency.

[0092] As an example, the rubber band support mechanism 42 includes four rubber band hooks 47 symmetrically arranged around the rubber band feeding shaft 41. Each rubber band hook 47 is connected to a hook drive mechanism 48. Under the control of the four hook drive mechanisms 48, the four rubber band hooks 47 either converge towards the center or expand outwards. When converging towards the center, the four rubber band hooks 47 converge into the rubber band on the rubber band feeding shaft 41; when expanding outwards, the four rubber band hooks 47 expand the rubber band on the rubber band feeding shaft 41.

[0093] The aforementioned rubber band support hooks 47 and support hook driving mechanisms 48 are mounted on the base plate 49 of the support mechanism. The four support hook driving mechanisms 48 can be cylinders, which are mounted at the four corners of the rubber band support mechanism 42. The direction of action of each support hook driving mechanism 48 is inclined, so that the stretched rubber band is rectangular.

[0094] The support opening moving mechanism is connected to the support opening mechanism base plate 49, driving the support opening mechanism base plate 49 to move closer to or further away from the glove stack.

[0095] For example, the support mechanism base plate 49 is directly or indirectly disposed on the horizontal guide shaft 56. The support movement mechanism controls the support mechanism base plate 49 to move along the guide shaft. The support movement mechanism is not shown in the figure and can be various forms of power elements in the prior art such as cylinders and motors.

[0096] To prevent spatial conflicts between the support mechanism base plate 49 and the rubber band feeding shaft 41, a clearance window 50 is provided on the support mechanism base plate 49 for the rubber band feeding shaft 41 to pass through. When the support mechanism base plate 49 moves to the glove stack position, the glove stack is located inside the clearance window 50.

[0097] The aforementioned push plate moving mechanism 44 is disposed on the support mechanism base plate 49. The rubber band push plate 43 is connected to the push plate moving mechanism 44, and the push plate moving mechanism 44 and the rubber band push plate 43 move together with the support mechanism base plate 49. The rubber band push plate 43 is located between the support mechanism base plate 49 and the extended rubber band 46, so that the extended rubber band 46 can be retracted onto the glove stack.

[0098] To prevent the rubber bands 45 on the rubber band feeding shaft 41 from falling off the end, a rubber band limiting end plate 51 is provided at the end of the rubber band feeding shaft 41. The rubber band limiting end plate 51 can be circular or other shapes.

[0099] A telescopic tongue 32 may be provided below the aforementioned lower support plate 24. The telescopic tongue 32 is located near the root of the glove stack. The telescopic tongue 32 is connected to a tongue drive mechanism 33 that controls the extension or retraction of the telescopic tongue 32 to the lower support plate 24.

[0100] The gloves are stacked on the lower support plate 24, with the base of the gloves extending beyond the edge of the lower support plate 24. This is to facilitate subsequent bundling. At this time, the telescopic tongue 32 is extended to support the base of the gloves stack. After the gloves are bundled, the telescopic tongue 32 needs to be retracted into the lower support plate 24.

[0101] In this utility model, the support opening moving mechanism and the material picking hand mold driving mechanism 22 can be the same driving mechanism. The rubber band support opening mechanism 42 also includes a second linkage mechanism 52 that connects or disconnects the rubber band support opening mechanism 42 and the material picking hand mold 21.

[0102] The second linkage mechanism 52 includes a vertically arranged linkage column 53, which is connected to a linkage column drive mechanism 54 that controls the vertical movement of the linkage column 53. The material handling hand mold 21 is provided with a second linkage hole 55 that cooperates with the linkage column 53.

[0103] This invention enables a single drive mechanism to control two parts, reducing the number of power mechanisms and shrinking the size of the equipment.

[0104] 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.
