TECHNICAL FIELD
[0001] The present application relates to the technical field of glove production equipment, in particular to a glove edge pressing and wrist turning device. BACKGROUND
[0002] In the glove production process, the gloves after dipping and forming need to be processed by turning the wrist opening to facilitate subsequent demolding, packaging and other processes. The invention patent with publication number CN222062422U discloses a glove wrist turning device, which includes a glove conveying mechanism, a opening supporting assembly and a turning assembly. The glove conveying mechanism can convey the gloves to the vicinity of the opening supporting assembly; the opening supporting assembly includes two pairs of opening supporting claws which can be inserted into the wrist opening of the gloves to open the wrist opening; the turning assembly includes a pair of openable and closable clamping plates which can squeeze the gloves conveyed between the clamping plates; the opening supporting claws and the clamping plates can move relatively to turn the wrist opening of the gloves outward. The scheme has the following shortcomings: firstly, the opening supporting claws need to be precisely inserted into the wrist opening, which requires high positioning accuracy and may cause insertion failure at high speed production. Since the opening supporting claws must be aligned with the wrist opening and inserted into it, the position and posture of the wrist opening are strictly required, and slight deviation or deformation of the wrist opening may cause insertion failure, affecting the continuity and stability of the equipment operation. Secondly, the timing sequence of the opening supporting claws and the clamping plates requires strict coordination, the process steps are complex, and the wrist turning efficiency is low. The scheme needs to complete multiple steps such as insertion of the opening supporting claws, opening of the opening supporting claws, closing and squeezing of the clamping plates, relative movement of the clamping plates and the opening supporting claws, etc., which requires high timing sequence accuracy between steps, is complicated, has a long single wrist turning period, and limits the overall production efficiency. Thirdly, the position of the opening supporting claws clamped in the wrist opening is difficult to accurately control, resulting in different wrist turning sizes each time and poor wrist turning accuracy. The clamping depth and circumferential position of the opening supporting claws in the wrist opening are difficult to keep consistent, making the edges of the turned wrist opening uneven and the turning width uneven, which affects the product appearance quality and the consistency of the subsequent packaging process. Fourthly, during the process of inserting the opening supporting claws into the wrist opening and opening outward, the opening supporting claws directly contact and apply tension to the inner surface of the gloves, which may scratch or wear the inner surface of the gloves, and even cause the gloves to be torn, resulting in product scrap and reducing the product yield. Therefore, there is an urgent need for a wrist turning device with a more reasonable structure, higher wrist turning efficiency and accuracy, and less damage to the gloves. SUMMARY
[0003] The purpose of the present application is to overcome the above-mentioned deficiencies in the prior art and provide a glove edge pressing and wrist turning device which opens the wrist opening by limiting and opening the wrist opening with the pressing plate and the conveying member, and turns the wrist by the clamping plate passing through the channel, with compact structure, high wrist turning efficiency and accuracy.
[0004] The technical scheme adopted by the present application to solve its technical problems is as follows: The glove edge-pressing and wrist-turning device comprises a conveying mechanism, an edge-pressing mechanism and a wrist-turning mechanism. The conveying mechanism comprises two sets of conveying members and two sets of mounting plates, the two sets of conveying members are respectively mounted on the two sets of mounting plates, and a channel for passing gloves is formed between the two sets of conveying members. The edge-pressing mechanism comprises two sets of relatively movable pressing plates, the two sets of pressing plates are respectively mounted on two corresponding sets of mounting plates, the pressing plates can be moved towards the channel to approach the conveying members, so that the rib of the glove wrist opening is limited between the end of the pressing plate and the outside of the corresponding conveying member, and the wrist opening is opened by the relative movement of the two sets of pressing plates. The wrist-turning mechanism comprises a pair of openable and closable clamping plates, the clamping plates are arranged to be liftable and initially located below the channel, for clamping the glove after the wrist opening is opened, and moving upwards to pass through the channel between the two sets of conveying members, so that the wrist opening is folded outward.
[0005] The rib is limited and the wrist opening is opened by the cooperation of the pressing plate and the conveying member on the outside, instead of the structure of the opening jaw which needs to be accurately inserted, without the need for accurate alignment, the structure is simpler, and the action is more reliable. The clamping plate passes through the channel between the conveying members to complete the wrist turning, the action path is direct, and the wrist turning precision is high.
[0006] As a preferred, the end of the pressing plate is provided with a pressing head bent towards the channel. The bent pressing head can more accurately press the rib area, improving the limiting effect.
[0007] As a preferred, the conveying member is an elastic belt with a circular cross section. The elastic belt with a circular cross section can provide sufficient friction force to clamp the glove wrist opening, avoid damage to the glove, and make the conveying process more stable and reliable. At the same time, the elastic deformation ability of the elastic belt can provide space for the clamping plate to pass through the channel.
[0008] As a preferred, the two sets of mounting plates are relatively movable, at least one of the two sets of mounting plates is provided with a first driving assembly for driving the corresponding mounting plate to move, and the mounting plate moves to drive the conveying member and the pressing plate to move together to open the wrist opening. By integrating the conveying member and the pressing plate with the mounting plate, the synchronous movement of the two is realized, ensuring the consistency and stability of the opening action.
[0009] As a preferred, the first driving assembly is an eccentric wheel, a gas cylinder or a lead screw. The appropriate driving mode can be selected according to the actual working condition, and the adaptability is strong.
[0010] Preferably, both sets of mounting plates are equipped with sliding plates, which are movable relative to each other. At least one set of sliding plates is equipped with a sixth drive assembly to drive its movement. The pressure plate is mounted on the sliding plate, and its pressure head can extend into the wrist opening of the glove. When the two sets of sliding plates move relative to each other, the pressure head of the pressure plate opens the wrist opening of the glove and simultaneously pulls the conveyor to elastically deform, increasing the width of the channel for the clamp to pass through. By using the sliding plate to drive the pressure head to extend into the wrist opening and utilizing the elastic deformation of the conveyor to increase the channel width, more space is provided for the clamp to pass through, reducing the accuracy requirements of the initial spacing of the conveyor and making it more adaptable.
[0011] Preferably, the sixth drive component is an eccentric wheel, a cylinder, or a lead screw. A suitable drive method can be selected according to the actual working conditions, offering strong adaptability.
[0012] Preferably, the pressure plate is rotatably mounted on the mounting plate. The pressure plate is fed and withdrawn via rotation, resulting in a simple structure, flexible operation, and minimal space occupation.
[0013] Preferably, the mounting plate is also provided with a protective cover, which is located above the pressure plate, and the side of the protective cover near the channel has a downward sloping surface. The protective cover can shield the pressure plate mechanism to prevent foreign objects from entering, and the sloping surface at the bottom of the glove during discharge also serves to guide and support it.

DETAILED DESCRIPTION
[0016] The technical solutions of the present application will be further described below with specific examples and in conjunction with the drawings. Example 1
[0017] As shown in a glove edge pressing and wrist turning device, comprising a conveying mechanism, an edge pressing mechanism, a wrist turning mechanism and a discharging mechanism. Figures 1 to 7
[0018] The conveying mechanism is mounted on the rack 15 and comprises two groups of conveying members 1 rotating along the glove conveying direction (Y direction) and two groups of mounting plates 2. Each group of conveying members 1 is arranged around at least two pulleys 14, wherein the driving pulley is driven to rotate by a motor, and two groups of motors drive two groups of conveying members 1 to synchronously drive or differentially drive. The two groups of conveying members 1 form a channel 12 for the gloves 13 to pass through, and when conveying, the two groups of conveying members 1 clamp the wrist opening of the gloves 13, so that the gloves 13 naturally droop, and when the two groups of motors drive the two groups of conveying members 1 to differentially rotate, the posture of the gloves can be adjusted. The conveying member 1 is preferably an elastic belt with a circular cross section, which can provide sufficient friction force to reliably clamp the wrist opening of the gloves, and its elasticity can also avoid clamping damage to the gloves. The pressing plate 3 is used to cooperate with the conveying member 1 from the outside of the wrist opening to limit the position, without the need to insert any part into the inside of the wrist opening to complete the opening of the wrist opening, which fundamentally avoids the problem of discontinuous operation and poor stability of the equipment caused by the insertion of the opening support claw not being in place, and has stronger fault tolerance for the position and posture of the wrist opening, thereby improving the operation reliability of the equipment.
[0019] The mounting plate 2 is slidingly arranged on the rack 15 and is configured on a conventional guide rail assembly (not shown in the figure), and the mounting plate 2 can move close to or away from each other along the glove wrist opening opening direction (X direction) under the driving of the first driving assembly 7. The first driving assembly 7 can be an eccentric mechanism, a pneumatic cylinder or a lead screw mechanism, etc., which can realize linear reciprocating motion.
[0020] The edge pressing mechanism comprises two sets of pressing plates 3, which are respectively installed on two sets of corresponding mounting plates 2. Specifically, each set of pressing plate 3 is rotatably arranged on the corresponding mounting plate 2 through a rotating shaft, and the pressing plate 3 is located on the inner side of the conveying member 1, i.e. the inner side of the channel 12; in addition, the pressing plate 3 can also be slidingly arranged on the mounting plate 2, and the sliding arrangement adopts a conventional structure, but the structure of the sliding arrangement is more complex than that of the rotating arrangement, and the stroke is also large, so the rotating arrangement of the pressing plate 3 is preferred in the embodiment. The pressing plate 3 can be flipped to the direction of the channel 12 under the driving of the second driving assembly 8, so as to limit the rib of the wrist opening of the glove 13 to the end of the pressing plate 3 and the outer side of the corresponding conveying member 1, so that the rib is kept fixed during the subsequent wrist flipping process, and the wrist opening is prevented from being lifted by the clamping plate. The second driving assembly 8 can be a cylinder, a motor or a cam mechanism, etc., which can drive the pressing plate 3 to rotate around the rotating shaft. In order to achieve more accurate limiting effect, the end of the pressing plate 3 is provided with a pressing head 31 bent to the direction of the channel 12, and the surface of the pressing head 31 is made of soft material such as rubber or coated with a soft material layer, so as to increase the friction and prevent damage to the glove.
[0021] When the pressing plate 3 limits the rib of the wrist opening on the conveying member 1, the first driving assembly 7 pulls the two sets of mounting plates 2 to move away from each other along the X direction, driving the conveying member 1 and the pressing plate 3 to move away from each other, so as to open the wrist opening along the X direction. As known by those skilled in the art, the first driving assembly 7 can also pull one set of mounting plates 2 to move away from each other along the X direction, as long as the two sets of mounting plates 2 can move relative to each other to achieve the purpose. If so, the corresponding mounting plate 2 can also be arranged to move on one side; but if the wrist opening is opened on both sides, it has better protection for the wrist opening, and generally two sets of mounting plates 2 are used to move relative to each other. It should be noted that whether the conveying member 1 starts to be synchronous transmission or differential transmission, the conveying member 1 needs to stop transmission when the glove is sent to the wrist opening opening station. Unlike the complex steps of the comparative document, the embodiment only needs two main actions of flipping and limiting of the pressing plate 3 and moving away of the mounting plate 2 to complete the opening of the wrist opening, the process steps are greatly simplified, the timing cooperation difficulty between the actions is reduced, and the wrist flipping cycle is significantly shortened, thereby significantly improving the wrist flipping efficiency.
[0022] The mounting plate 2 is also provided with a protective cover 4 located above the pressing plate 3, which can shield the pressing plate 3 and its driving mechanism to prevent foreign matter from falling in. The side of the protective cover 4 close to the channel 12 is provided with an inclined surface 41 inclined downward, which can hold the lower part of the glove 13 during the discharging process, so that the clamping jaw 6 forms a dragging action on the glove 13, which is beneficial to the forward placement of the glove.
[0023] The wrist turning mechanism comprises a pair of clamping plates 5 which can be opened and closed along the X direction, and the clamping plates 5 are arranged to be lifted along the vertical direction (Z direction) and initially positioned below the passage 12. Specifically, the two clamping plates 5 are installed on the third driving assembly 9 and driven by the third driving assembly 9 to realize the opening and closing along the X direction to realize the clamping action. The third driving assembly 9 can be an opening and closing cylinder, two groups of independently configured cylinders, or a screw rod mechanism with opposite screw directions, etc. In this embodiment, the opening and closing clamping plates 5 are also two clamping plates which are relatively rotated. This clamping plate structure can be two clamping plates which are simultaneously relatively rotated, or one moving plate and one static plate, as long as the gloves can be clamped. This structure belongs to the prior art and will not be described in detail. The third driving assembly 9 is installed on the fourth driving assembly 10 and driven by the fourth driving assembly 10 to realize the lifting motion along the Z direction. The fourth driving assembly 10 can be a linear module, a motor belt combination, a cylinder guide rod combination, a motor screw rod combination, or a gear and rack combination which can realize the linear lifting motion.
[0024] After the edge pressing mechanism and the conveying mechanism cooperate to open the wrist opening of the glove 13, the clamping plate 5 acts to clamp the glove, and then, under the action of the fourth driving assembly 10, the clamping plate 5 moves upward along the vertical direction and passes through the passage 12 between the two groups of conveying members 1. Since the rib of the wrist opening is limited and fixed by the pressing plate 3 and the conveying member 1, the upward movement of the clamping plate 5 forces the wrist opening to be folded outward relative to the glove body, completing the wrist turning action. After the clamping plate 5 moves upward to the position, the wrist turning process is completed. The so-called limited and fixed refers to that after the pressing plate 3 acts and cooperates with the conveying member 1, the gap between the pressing plate 3 and the conveying member 1 is smaller than the thickness of the rib of the wrist opening, so that the rib of the wrist opening is located outside the conveying member 1, i.e. outside the passage 12, and will not slide out of the gap. During the entire wrist turning process, the pressing plate 3 always maintains the limited state of the rib of the wrist opening, ensuring the consistency of the wrist turning size. By limiting the rib of the wrist opening from the end of the pressing plate 3 and the outside of the conveying member 1 together, the limiting position is determined by the geometric relationship between the pressing plate 3 and the conveying member 1, and the limiting position height is consistent each time, ensuring that the edge of the folded wrist opening is neat and the width of the folded edge is uniform, and the wrist turning precision is significantly improved, which is conducive to the standardized operation of the subsequent packaging process. In addition, compared with the supporting jaw in the prior art which is inserted into the inside of the wrist opening and expanded outward, the supporting jaw directly contacts the inner surface of the glove and exerts the supporting tension, which is easy to scratch or wear the inner surface of the glove, and even to break the wrist opening. The pressing plate 3 of the present embodiment always acts on the rib of the wrist opening and cooperates with the conveying member 1 to limit and open from the outside, without contacting the inner surface of the glove, which fundamentally eliminates the scratching and wearing of the inner surface of the glove, and will not break the wrist opening, effectively improving the product yield.
[0025] The discharge mechanism includes a gripper 6 and a fifth drive assembly 11 that drives the gripper 6 to move up and down in the Z direction and translate in the X direction. After the wrist is flipped, the gripper 6 first clamps the glove 13 with the wrist opening flipped under the drive of the fifth drive assembly 11. Then, the clamping plate 5 opens under the drive of the third drive assembly 9 and descends and resets along the Z direction under the drive of the fourth drive assembly 10. The pressure plate 3 flips and resets under the drive of the second drive assembly 8. Next, the gripper 6 pulls the glove 13 away from the channel 12 along the X direction under the drive of the fifth drive assembly 11. Finally, the two sets of mounting plates 2 move towards each other and resets along the X direction under the drive of the first drive assembly 7, completing the discharge. The function of the fifth drive assembly 11 is divided into two parts: Z-axis lifting and X-axis translation. The lifting part can adopt a structure such as a cylinder, a gear and rack combination, or a gear and screw combination; the translation part can adopt a structure similar to the fourth drive assembly 10, such as a linear module, a motor belt combination, a cylinder guide rod combination, a motor and screw combination, or a gear and rack combination. Example 2
[0026] like Figure 8 and Figure 9 As shown, the difference between this embodiment and embodiment 1 lies in the installation method of the pressure plate 3 and the cooperation method between the pressure plate 3 and the conveyor 1.
[0027] At least one set of sliding plates 16 is provided on each of the two sets of mounting plates 2. The sliding plates 16 can move relative to each other in the X direction. The sliding plates 16 are equipped with a sixth drive assembly 17 to drive their movement, and are also equipped with a conventional guide rail structure. As described in Embodiment 1 above, unidirectional movement of the pressure plate 3 is also allowed. However, for the sake of structural symmetry, it is generally set to move in both directions. The pressure plate 3 is rotatably mounted on the sliding plate 16. When the pressure plate 3 flips in the direction of the channel 12, the pressure head 31 can extend into the wrist opening of the glove 13. Specifically, after the glove 13 is conveyed to the wrist-flipping station in the channel 12, the second drive assembly 8 drives the pressure plate 3 to move, so that the pressure head 31 extends into the wrist opening from the inside. Although the pressure head 31 extends partially, the stable opening is mainly achieved by external limiting structure, which is different from the traditional structure that relies entirely on internal support to open. Subsequently, the sixth drive assembly 17 drives the slide plate 16 to move relative to it in the X direction. The pressure head 31 of the pressure plate 3 opens the wrist opening from inside. At the same time, the movement of the slide plate 16 causes the transmission component 1 to elastically deform through the pressure head 31, thereby increasing the width of the channel 12 and providing more space for the clamping plate 5 to pass through the channel 12. The sixth drive assembly 17 can be an eccentric wheel mechanism, cylinder, or lead screw mechanism, or other device capable of linear reciprocating motion.
[0028] It needs to be particularly pointed out that the pressure head 31 in the embodiment partially extends into the inside of the glove wrist opening, but its working mode and effect are essentially different from those of the support opening claw in the comparative document: 1. The surface of the pressure head 31 is made of soft material such as rubber or is coated with a soft material layer, and when it contacts the inner surface of the glove, it is flexible contact and will not cause scratches; 2. After the pressure head 31 extends into the wrist opening, it is not forced to open the wrist opening by expanding outward, but translates as a whole with the sliding plate 16, and the main action between the pressure head 31 and the inner surface of the glove is static friction, and there is almost no relative sliding, so it will not cause wear to the inner surface of the glove; 3. The role of the pressure head 31 is to assist positioning and drive the elastic deformation of the conveying member 1, and the main driving force for opening the wrist opening comes from the translational movement of the sliding plate 16, rather than the radial support and expansion of the pressure head 31 inside the wrist opening. The force borne by the wrist opening rib is mainly borne by the outside of the conveying member 1 and the pressing plate 3, and the inside of the wrist opening will not bear concentrated support force, so the situation of supporting and breaking the wrist opening will not occur. In addition, it needs to be pointed out that since the pressure head 31 only partially extends into the wrist opening, it avoids the damage to the glove caused by the traditional support opening claw due to excessive insertion or support expansion, and at the same time of realizing reliable opening of the wrist opening, effectively protects the integrity of the inner surface of the glove and the strength of the wrist opening.
[0029] Similarly, as in Embodiment 1, when the glove is sent to the wrist opening opening station, the conveying member 1 needs to stop transmission.
[0030] The conveying member 1 adopts an elastic belt with a circular cross section, which has the characteristic that the cross-sectional shape can change after being stressed. When the mounting plate 2 moves away, the conveying member 1 is stretched outward, and the width of the channel 12 increases, which facilitates the smooth passage of the glove 13 from the channel 12 after the clamping plate 5 clamps the glove 13, avoiding interference between the clamping plate 5 and the conveying member 1.
[0031] It is worth noting that in the embodiment, when installing the mounting plate 2, the distance between the two groups of mounting plates 2 needs to be set larger, at least not to interfere with the lifting of the clamping plate 5.
