It involves multiple fields, including mechanical design, automation control, textile engineering, etc. It requires precise design to ensure accurate grasping of gloves and perform rotation and sewing operations. This involves careful design of components such as robotic arms, jigs, and rotating devices to adapt to gloves of different materials and sizes. In the prior art, manual transplanting is generally used, but the efficiency of manual transplanting is low (single-shift production capacity < 8000 pieces), the positioning accuracy is poor (angle deviation > ±3°), and the glove breakage rate reaches 3.5%. Moreover, the traditional rotating mechanism is driven by a motor, increasing the cost by 20%, and the maintenance cycle is only 2000 hours.

[0007] A U-shaped groove is arranged on the linear bearing fixing seat, and the second guide rail passes through the U-shaped groove and is connected with the claw device.

[0008] The main transplanting device includes a transplanting motor, which is provided with a transplanting driving wheel. The transplanting driving wheel is connected with a transplanting driven wheel through a transplanting synchronous belt, and an upper sliding track one and a lower sliding track one are respectively arranged above and below the transplanting synchronous belt. The upper side and the lower side of the main sliding block are respectively sleeved on the upper sliding track one and the lower sliding track one, and the middle part of the main sliding block is fixed with the transplanting synchronous belt. The driven transplanting device includes an upper sliding track two and a lower sliding track two. The position of the upper sliding track two is on the same plane as the position of the upper sliding track one, and the position of the lower sliding track two is on the same plane as the position of the lower sliding track one.

[0013] The glove grasping and rotating sewing machine of the present invention has the following beneficial effects: 1. The glove transplanting mechanism in the present invention is a limit tray type transplanting system. It uses a high-precision linear guide rail as the movement track for transplanting to ensure the straightness and stability of the transplanting process. A limiting device is set, using limit switches and mechanical stoppers to accurately control the position of glove transplanting, making the limiting device highly reliable and accurate, ensuring that the position of each transplanting is consistent. The transplanting power uses a stepping motor, which is selected according to the production rhythm and accuracy requirements to ensure smooth movement. The rear end of the glove transplanting plate has an inclined surface design to prevent the gloves from curling.

[0014] 2. In the glove grasping mechanism of the present invention, a stainless steel spring is built into the air jaw finger part (i.e., on the second guide rail). The automatic compensation of the glove thickness change is achieved through the spring compression amount, and the spring pre-tightening force is adjustable to adapt to the grasping requirements of gloves of different materials.

[0015] 3. In the glove rotating mechanism of the present invention, precise gear transmission is adopted. Parameters such as the module and number of teeth of the gears need to be calculated and optimized to ensure that the rotation angle accuracy is 90° ± a certain error range (such as ±0.5°). The gear material should have high strength and wear resistance. Special jaws are designed for the upper clamping device and the lower jaw device to be able to reliably clamp the gloves and keep the gloves stable during rotation. In addition to the limiting function of the gear mechanism itself, an auxiliary limiting device is added to the limiting structure, using Hall induction and mechanical limit blocks (i.e., hard limit blocks) to further ensure the accuracy and repeatability of the rotation angle. Compared with the traditional motor drive (±1°), the accuracy is improved by 70%, meeting the requirements of the glove sewing process, the cost is reduced by 30%, and no encoder and servo motor are required.

[0016] 4. The glove transmission mechanism in the present invention adopts a two-stage precision transplanting system, namely the first-stage transmission, drive system (the stepping motor drives through a synchronous belt), and guide rail system: the linear guide rail is equipped with a Hall sensor, the last-stage transmission and mechanical air. The transmission beat is shortened by 40% compared with manual operation, the single-shift production capacity reaches 12,000 pieces, the straightness error of the guide rail is <0.03 mm / m, and the transmission error of the synchronous belt is <0.05 mm, greatly enhancing its stability.

[0017] 5. The glove feeding mechanism in the present invention is a gear-rack layered limit glove conveying mechanism, which adopts the meshing transmission of a gear and a rack plate, and is driven by a stepping motor. The transmission error is ≤0.05 mm, which is 83% higher than that of traditional chains / belts. The gear life exceeds 8,000 hours, and the maintenance cost is reduced by 75%. It accurately controls the displacement and speed of glove conveying, and closely adapts to the operation rhythm of the grasping and transplanting mechanism; the innovative layered glove limit box reduces the breakage rate from 3.5% to 1.4%. The gloves are fixed through multiple limit cavities to prevent conveying deviation and dumping, and the height of the limit cavity is adjustable to quickly adapt to gloves of different thicknesses; a Hall sensor is set to monitor the position of the glove limit box in real time, and the feedback signal is linked to the control system to achieve precise docking of the conveying and grasping and transplanting mechanisms, improving the collaborative efficiency of the production line. Traditional equipment needs to be customized and modified to adapt to different gloves; the height of the limit cavity in the present invention can be quickly adjusted by replacing the module, and the specification switching can be completed within 10 minutes. The applicable glove thickness range is expanded by 3 times, significantly improving the flexibility of the production line. BRIEF DESCRIPTION OF THE DRAWINGS

After the gloves manually stacked on the glove feeding mechanism are grasped by the glove grasping mechanism in the present invention, they are then transplanted to the glove rotating mechanism through the glove transplanting mechanism. After the gloves are spread and rotated by 90° through the glove rotating mechanism, they are sent to the glove placement table 3 of the edge sewing machine 2 through the glove transmission mechanism for edge sewing operation.

[0021] Further, the glove feeding mechanism 48 in the present invention includes a rack plate. A number of glove limiting boxes 49 are provided on the rack plate 48.

[0022] Further, the glove grasping mechanism in the present invention includes a grasping cylinder mounting plate 16 above the guide rail mounting plate 6. The grasping cylinder 5 is mounted on the grasping cylinder mounting plate 16. The grasping cylinder 5 is connected to the guide rail mounting plate 6. A linear bearing fixing seat 7 is provided below the guide rail mounting plate 6. A first guide rail 8 is provided between the guide rail mounting plate 6 and the linear bearing fixing seat 7. A second guide rail 9 is provided inside the first guide rail 8. There are 2 mutually parallel first guide rails 8, and the 2 first guide rails 8 are respectively located on both sides of the linear bearing fixing seat 7; there are 2 mutually parallel second guide rails 9, and the 2 second guide rails 9 are located inside the 2 first guide rails 8. 2 U-shaped grooves 14 are provided on the linear bearing fixing seat 7. The two second guide rails 9 respectively pass through the corresponding U-shaped grooves 14, and the ends of the two second guide rails 9 are both connected to the jaw device 10. The jaw device 10 is located below the linear bearing fixing seat 7.

[0023] The guide rail mounting plate 6 is driven by the grasping cylinder 5 to move up and down, so that the first guide rail 8 and the second guide rail 9 both achieve lifting through the linear bearing 11, thereby driving the jaw device 10 to move up and down, for grasping the stacked gloves in the glove feeding mechanism and feeding them into the glove transplanting mechanism.

[0024] Furthermore, floating joints 15 are provided on both sides of the output shaft of the grasping cylinder 5 here. A grasping limit block 12 is provided at the end of the first guide rail 8. The grasping limit block 12 is located on the linear bearing fixing seat 7. A spring 13 is sleeved outside the second guide rail 9. The spring 12 is located between the guide rail mounting plate 6 and the jaw device 10. The change in the glove thickness is automatically compensated by the compression amount of the spring 12, and the pre-tightening force of the spring 12 is adjustable to adapt to the grasping requirements of gloves of different materials. Compared with the traditional pneumatic pressure reducing valve and pressure sensor, the cost of a single device is reduced by 15%, and the service life reaches more than 100,000 times.

[0025] Further, the glove transplanting mechanism in the present invention includes an active transplanting device and a driven transplanting device. The active transplanting device includes a transplanting motor 20, the transplanting motor 20 is provided with a transplanting driving wheel 21, the transplanting driving wheel 21 is connected with a transplanting driven wheel 22 through a transplanting synchronous belt 23, and an upper sliding track one 24 and a lower sliding track one 25 are respectively arranged above and below the transplanting synchronous belt 23. The upper side and the lower side of the active sliding block 17 are respectively sleeved on the upper sliding track one 24 and the lower sliding track one 25, and the middle part of the active sliding block 17 is fixed to the transplanting synchronous belt 23. The driven transplanting device includes an upper sliding track two 26 and a lower sliding track two 27. The position of the upper sliding track two 26 is in the same plane as the position of the upper sliding track one 24, and both the upper sliding track one 24 and the upper sliding track two 26 pass through a linear bearing fixing seat 7. The position of the lower sliding track one 25 is in the same plane as the position of the lower sliding track two 27, and the upper side and the lower side of the driven sliding block 18 are respectively sleeved on the upper sliding track two 26 and the lower sliding track two 27. A glove transplanting plate 19 is arranged between the active sliding block 17 and the driven sliding block 18. Driven by the transplanting motor 20, the transplanting synchronous belt 23 is driven to move, so as to drive the glove transplanting plate 19 to move along the sliding track, and thus the glove in the clamping jaw device 10 is conveyed to the glove rotating mechanism.

[0026] Furthermore, at both ends of the upper sliding track one 24, the lower sliding track one 25, the upper sliding track two 26 and the lower sliding track two 27, transplanting limit blocks 28 are arranged. A transplanting Hall sensor 29 is arranged on one side of the transplanting driven wheel.

[0027] Further, the glove rotating mechanism in the present invention includes an upper clamping jaw device 30 and a lower clamping jaw device 31. The position of the lower clamping jaw device 31 matches that of the glove transplanting plate 19, so that the glove in the glove transplanting plate 19 just falls into the lower clamping jaw device 31. The upper clamping jaw device 30 is connected with an upper clamping jaw cylinder 32, the upper clamping jaw cylinder 32 is connected with a rotating gear 33, a rotating motor 34 is arranged on the back side of the rotating gear 33, the rotating motor 34 is connected with a driving gear 35, and the driving gear 35 meshes with the rotating gear 33. After the rotating motor 34 is started, the driving gear 35 rotates, so as to drive the rotating gear 33 to rotate. The upper clamping jaw device 30 can not only move up and down under the drive of the upper clamping jaw cylinder 32, but also rotate along with the rotating gear 33. The tooth part of the rotating gear 33 accounts for about one quarter of the rotating gear 33, so that the upper clamping jaw device just rotates 90°.

[0028] Furthermore, a rotary Hall sensor 36 is provided on the side of the rotary gear 33, and a hard limit member 38 and a hydraulic buffer 37 are provided on the upper jaw cylinder 32. The rotary Hall sensor 36 and the mechanical limit block (i.e., the hard limit block 38) are used to further ensure the accuracy and repeatability of the rotation angle. Compared with the traditional motor drive (±1°), the accuracy is improved by 70%, meeting the requirements of the glove sewing process, reducing the cost by 30%, and eliminating the need for an encoder and a servo motor.

[0029] Furthermore, the glove transmission mechanism in the present invention includes a transmission plate 39 inclinedly installed on the frame 1. A transmission motor 40 is provided on the side of the transmission plate 39. The output end of the transmission motor 40 is provided with a transmission driving wheel 41. The transmission driving wheel 41 is connected to a transmission driven wheel 43 through a transmission synchronous belt 42. A long slot 46 is provided on the transmission plate 39. A transmission connecting block 47 is provided at the bottom of the transmission jaw mounting seat 44. The transmission connecting block 47 passes through the long slot 46 and is fixed to the transmission synchronous belt 42. The transmission synchronous belt 42 fixes the transmission jaw mounting seat 44. The transmission jaw mounting seat 44 is installed with a transmission jaw device 45. The transmission jaw device 45 cooperates with the glove placement table 3 of the glove sewing machine 2 to transfer the glove rotated and expanded from the headgear rotating mechanism to the glove placement table 3, facilitating the edge sewing of the glove by the glove sewing machine 2.

[0030] The working process of the present invention is as follows: 1. Glove grasping: Through the telescopic movement of the grasping cylinder 5, the glove stacked on the glove limit box 49 is grasped by the jaw device 10 or other grasping components. The grasping position and force need to be precisely adjusted to ensure stable glove grasping without damaging the glove.

[0031] 2. Glove transplanting: The glove transplanting mechanism is activated to perform limit transplanting on the grasped glove. The transplanting mechanism uses a linear guide rail to transplant the glove from the glove machine position to the 90° rotating mechanism. During the transplanting process, the position accuracy of the glove on the transplanting path is ensured through the limit device.

[0032] 3. 90° rotation: After the glove reaches the 90° rotating mechanism, the clamping device of the glove rotating mechanism opens and clamps the glove. The glove rotating mechanism realizes 90° rotation through the setting of the tooth part of the driving gear 33, avoiding the accuracy and stability problems caused by using the rotary motor 34. The design of the tooth part of the driving gear 33 needs to ensure the accuracy and repeatability of the rotation angle. After the rotation is completed, the clamping device releases the glove.

[0033] 4. Glove transmission: The rail - type mechanical air gripper acts to clamp the rotated glove and transfer it to the designated position of the glove sewing machine 2. The mechanical air gripper moves along the rail, enabling precise positioning and transplanting to ensure that the glove is accurately placed on the sewing machine for subsequent processing.

[0034] In the present invention, the glove feeding mechanism uses the feeding motor 52 as a stepper motor. Taking the stepper motor as the power source, through the meshing transmission of the gear and the rack plate 48, it provides stable power for glove feeding, ensures that the conveying speed and displacement accuracy are controllable, and adapts to the rhythm of the glove grasping mechanism. Its transmission ratio designs the modulus and number of teeth of the gear and the rack according to the glove conveying beat, ensuring a smooth and impact-free conveying process. Moreover, the glove limiting box 49 adopts a layered structure, adapting to the stacked form of the boxed gloves. Each layer precisely limits the position of the gloves, preventing the gloves from shifting or toppling during the conveying process. The glove limiting box 49 cooperates with the feeding guide rail 50, and the movement direction is restricted by the guide rail, ensuring the position accuracy of the gloves on the conveying path and facilitating subsequent grasping and transplanting. The feeding guide rail 50 is a high-precision guide rail, providing support and guidance for the glove limiting box 49, reducing the movement friction, ensuring the straightness and stability of the conveying process, and reducing the wear of the mechanism.

[0035] In the glove grasping mechanism of the present invention, a suitable cylinder is selected, and the model and parameters of the cylinder, such as the cylinder diameter, stroke, etc., are determined according to the weight and size of the glove. The shape and size of the air claw of the claw device 10 need to match the outer shape of the glove to ensure the stability and reliability of grasping. A pressure regulating device is equipped, which can adjust the grasping pressure according to the material and thickness of the glove to avoid damaging the glove.

[0036] In the glove transplanting mechanism of the present invention, a high-precision linear guide rail is used as the movement track for transplanting, ensuring the straightness and stability of the transplanting process. Transplanting limit blocks 28 are set, and limit switches and mechanical stoppers are used to accurately control the position of glove transplanting. The transplanting limit blocks 28 have high reliability and accuracy, ensuring that the position of each transplanting is consistent. The transplanting motor 20 uses a stepper motor, which is selected according to the production beat and accuracy requirements to ensure smooth movement.

[0037] In the glove rotating mechanism of the present invention, precise gear transmission is adopted. Parameters such as the modulus and number of teeth of the gear need to be calculated and optimized to ensure that the rotation angle accuracy is 90° ± a certain error range (such as ±0.5°). The gear material should have high strength and wear resistance. Special claws are set on the upper clamping device 30 and the lower clamping device 31, which can reliably clamp the glove and keep the glove stable during the rotation process. In addition to the limiting function of the gear mechanism itself, an auxiliary limiting device is added, using a rotary Hall sensor 36 and a mechanical limit block (hard limit piece 38) to further ensure the accuracy and repeatability of the rotation angle.

[0038] In the glove transmission mechanism of the present invention, a high-precision guide rail is selected, and the model and specifications of the guide rail are determined according to the transmission distance and load requirements. The guide rail has good rigidity and straightness to ensure the smooth movement of the mechanical air gripper. The structure and grasping method of the transmission gripper 45 are adapted to the characteristics of the glove, and can accurately grasp the rotated glove. The opening and closing of the air gripper are controlled by a pneumatic system, and the grasping force can be adjusted. The transmission motor 40 is driven by a stepping motor and transmitted through the transmission synchronous belt 42 to achieve the precise movement of the mechanical air gripper on the guide rail. The sensor provides accurate position control and speed control to meet the high-precision requirements of glove transplantation.

[0039] The gripper device, the upper gripper device and the lower gripper device in the present invention are all needle-type gripper devices, and their specific structures and working methods are the same as those of the glove grasping device disclosed in the invention patent with the publication number of CN115924530A, and will not be elaborated here.

[0040] The above embodiments are only used to explain the inventive concept of the present invention, rather than limiting the protection scope of the rights of the present invention. Any non-substantive changes made to the present invention using this concept shall fall within the protection scope of the present invention.
