Description

Technical Field

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

[0002] In the field of dipped glove production, the traditional glove molding process has long relied on manual operation. For example, glove molding mainly involves manually slipping un-dipped knitted gloves onto the mold before the dipping production line automatically puts the gloves on for dipping. The core operation still requires manual intervention in slipping the gloves on. This traditional "manual" method is inefficient, costly, and the high-load, continuous operation easily leads to excessive strain on workers' bodies. It not only fails to improve production efficiency but also hinders the reduction of labor costs. Furthermore, it cannot better guarantee the consistency and quality of glove molding, and manual operation is difficult to control, mainly in the following aspects:

[0003] 1. Low production efficiency: Manual mold setting relies on workers' hand operations, which is limited by the frequency of human body movements (usually only 8-12 mold setting times per minute), making it difficult to meet the capacity requirements of large-scale production. Moreover, the speed of manual mold setting varies, and product quality is affected by the worker's skill level and working condition, making it difficult to guarantee consistency.

[0004] 2. High labor costs: The production of dipped gloves is a labor-intensive industry. A production line requires 6-12 mold-making workers. With the rising labor costs year by year, the cost disadvantage of traditional processes is becoming more and more obvious, and there are also problems such as difficulty in recruiting workers and long training cycles.

[0005] 3. High labor intensity and safety hazards: Long-term repetitive bending and raising of arms can easily lead to occupational health problems such as lumbar muscle strain and frozen shoulder in workers.

[0006] 4. Insufficient level of intelligence: Existing processes cannot be integrated with the factory's intelligent management system, lacking functions such as real-time monitoring of production data, fault early warning, and energy consumption analysis, making it difficult to meet the digital needs of modern intelligent manufacturing.

[0007] To address this, our company has developed an automatic die-fitting device for glove production, but currently lacks a corresponding clamping mechanism. Utility Model Content

[0008] In order to solve the above problems, the purpose of this utility model is to provide a gripping mechanism for glove production.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows: a gripping mechanism for glove production, comprising a finger cylinder and a gripper structure whose lower end moves left and right. An intermediate gripper is fixed to the end of the finger cylinder between the gripper structures, so that the outer end of the intermediate gripper and each side gripper structure form a gripping structure respectively.

[0010] Furthermore, each side of the gripper structure has a long strip-shaped outer gripper fixed to its outer end, and the outer end of the middle gripper is provided with a long strip-shaped clamping bar that is symmetrical on the left and right. The long strip-shaped clamping bar is parallel to the outer gripper, and the long strip-shaped clamping bar on each side corresponds to the outer gripper on each side. The arrangement direction of the outer gripper and the long strip-shaped clamping bar is perpendicular to the movement direction of the gripper structure.

[0011] Furthermore, the fixed end of the intermediate chuck is provided with front and rear fixed strips respectively. The intermediate chuck is fixedly connected to the front and rear edges of the lower end of the finger cylinder through the fixed strips. The front and rear fixed strips are used for the movement of the gripper structure.

[0012] Furthermore, it also includes an elastic telescopic structure fixed to the upper end of the finger cylinder.

[0013] Furthermore, the elastic telescopic structure includes a clamping guide rod and a clamping telescopic spring sleeved on the clamping guide rod. The upper end of the clamping guide rod passes through the clamping lifting beam and is fixed with a limit post. The upper end of the clamping telescopic spring contacts the lower surface of the clamping lifting beam, and the lower end of the clamping telescopic spring is used to push the finger cylinder downward.

[0014] Furthermore, a C-shaped connecting seat is fixed to the upper end of the finger cylinder, and a vertical reinforcing rib is fixed to the middle part of the connecting seat. The lower end of the clamping guide rod is fixedly connected to the upper end of the connecting seat, and the lower end of the clamping telescopic spring is in close contact with the upper end of the connecting seat.

[0015] Furthermore, it also includes a clamping main frame, which consists of left and right parts. The horizontal moving frame is supported at both ends by slide rails on the top of the left and right parts of the clamping main frame. Each side of the clamping main frame is also provided with a clamping horizontal moving rack parallel to the slide rail. The moving frame is provided with a drive device for driving the moving frame to move horizontally along the clamping horizontal moving rack. The vertical part of the moving frame is provided with a clamping lifting frame that can be raised and lowered by vertical slide rails. Vertical lifting clamping racks are provided on both sides of the vertical part of the moving frame. The clamping lifting frame is also provided with a drive device for driving the clamping lifting frame to be raised and lowered along the lifting clamping rack. The clamping lifting beam is horizontally fixed to one side of the clamping lifting frame.

[0016] Furthermore, the driving device of the mobile walking frame includes a walking frame drive shaft and a walking frame drive motor. The two ends of the walking frame drive shaft pass through the plate-like structures at both ends of the same side of the mobile walking frame and are fixed with walking frame drive gears. The walking frame drive gears at each end mesh with the clamping horizontal moving racks at each end. The walking frame drive motor is fixed at the plate-like structure at one end of the mobile walking frame and is connected to the walking frame drive shaft through gears.

[0017] Furthermore, the driving device for the clamping lifting frame includes a clamping frame drive shaft and a clamping frame drive motor. The two ends of the clamping frame drive shaft pass through the plate-like structures at both ends of the clamping lifting frame on the same side and are fixed with clamping frame drive gears. The clamping frame drive gears at each end mesh with the lifting clamping racks at each end. The clamping frame drive motor is fixed at the plate-like structure at one end of the clamping lifting frame and is connected to the clamping frame drive shaft through gears.

[0018] Furthermore, there are multiple finger cylinders arranged in sequence below the clamping lifting beam. Each finger cylinder is equipped with two clamping guide rods, and each clamping guide rod is equipped with a clamping telescopic spring.

[0019] With the above settings, when this utility model is in operation, the walking frame drive motor rotates, driving the entire moving walking frame to move upwards above the alternating feeding structure (mechanism). Then, the clamping frame drive motor drives the clamping lifting frame to move downwards, causing each finger cylinder to descend to correspond to each stack of gloves on the alternating feeding structure (mechanism), and the finger cylinders clamp. Additionally, photoelectric switches can be used, such as a photoelectric switch at the glove placement area of ​​the alternating feeding structure (mechanism), or a photoelectric switch light at the lower end of each finger cylinder. The purpose is to sense that as the stacked gloves decrease in thickness, the clamping lifting frame moves downwards accordingly. After the outer clamp and long strip clamp the gloves, the clamping frame drive motor reverses direction. The rotation causes the gripping lifting frame to move upwards. Then, the walking frame drive motor rotates in the opposite direction, moving the entire walking frame away from the alternating feeding structure (mechanism) and above the dynamic sorting mechanism. The gripping frame drive motor then rotates forward again, causing the gripping lifting frame to move downwards, so that each finger cylinder gripping the glove points downwards until it contacts the glove placement area of ​​the dynamic sorting mechanism. At this point, the finger cylinders are controlled to release the outer gripper and the long strip gripper, allowing the glove to be placed on the glove placement area of ​​the dynamic sorting mechanism. Then, the gripping frame drive motor and the walking frame drive motor work in sequence to return to the alternating feeding structure (mechanism), and the above actions are repeated continuously to grip and feed gloves.

[0020] The outer end of the middle clamp at the lower end of each finger cylinder of this invention forms a clamping structure with the side gripper structures, thereby achieving double clamping of the uppermost glove at each part. This not only results in a larger clamping area and a more secure clamping, but also improves the success rate of clamping. In addition, the elastic telescopic structure fixed at the upper end of the finger cylinder also plays a good role in pressing and contacting, allowing the outer clamp and the long strip clamp to better contact the glove, thereby further improving the success rate of grasping. It is also convenient to cooperate with alternating feeding mechanisms, dynamic sorting mechanisms, etc. to realize the automated glove covering.

[0021] The outer end of the middle clamp and the side gripper structures of this utility model form a special pneumatic gripper with a gripping structure. This structure facilitates the integration of pressure sensors and can automatically adjust the gripping force according to the glove thickness (1-5mm) and material (polyester, yarn / cotton). Moreover, this gripper structure solves the problem of grippers easily tearing knitted gloves. The gripping success rate is ≥99.5%, and it is compatible with all sizes of gloves from 5 to 12 without the need for manual clamp replacement. Attached Figure Description

[0027] like Figure 1-4 As shown, a gripping mechanism for glove production includes a finger cylinder 201 and a gripper structure 202 that moves left and right at the lower end of the finger cylinder 201. The finger cylinder 201, i.e., the pneumatic finger, mainly has a Y-shaped gripper or a flat gripper, preferably a flat gripper type finger cylinder 201. An intermediate clamp 204 is fixed to the end of the finger cylinder 201 between the gripper structures 202, so that the outer end of the intermediate clamp 204 forms a clamping structure with each side gripper structure 202 respectively.

[0028] To further improve the clamping effect, increase the clamping area, and effectively improve the success rate of clamping, each side of the gripper structure 202 has a long strip-shaped outer gripper 203 fixed to its outer end. The outer end of the middle gripper 204 is provided with symmetrical long strip-shaped clamping bars 205. The long strip-shaped clamping bars 205 are parallel to the outer grippers 203, and each side of the long strip-shaped clamping bars 205 corresponds to the outer grippers 203 on each side. The arrangement direction of the outer grippers 203 and the long strip-shaped clamping bars 205 is perpendicular to the moving direction of the gripper structure 202. The fixed end of the middle gripper 204 is provided with front and rear fixed bars 206. The middle gripper 204 is fixedly connected to the front and rear edges of the lower end of the finger cylinder 201 through the fixed bars 206. The front and rear fixed bars 206 are used for the movement of the gripper structure 202.

[0029] To facilitate the fixing of multiple finger cylinders 201 and to ensure better contact between the finger cylinders 201 and the glove when moving downwards, an elastic telescopic structure is also included at the upper end of the finger cylinders 201. This elastic telescopic structure includes a gripping guide rod 207 and a gripping telescopic spring 208 sleeved on the gripping guide rod 207. The upper end of the gripping guide rod 207 passes through the gripping lifting beam 209 and is fixed with a limit post 210. The upper end of the gripping telescopic spring 208 contacts the lower surface of the gripping lifting beam 209, and the lower end of the gripping telescopic spring 208 is used to push the finger cylinders downwards. Cylinder 201, finger cylinder 201 has a C-shaped connecting seat 211 fixed at its upper end. A vertical reinforcing rib is fixed in the middle of the connecting seat 211. The lower end of the clamping guide rod 207 is fixedly connected to the upper end of the connecting seat 211. The lower end of the clamping telescopic spring 208 is in close contact with the upper end of the connecting seat 211. There are multiple finger cylinders 201 arranged in sequence below the clamping lifting beam 209. Each finger cylinder 201 is provided with two clamping guide rods 207. Each clamping guide rod 207 is provided with a clamping telescopic spring 208.

[0030] To facilitate the movement of this row of finger cylinders 201 back and forth and up and down, thereby delivering the glove to the next workstation after gripping it, a gripping main frame 212 is also included. The gripping main frame 212 consists of left and right parts. The horizontal moving frame 213 is supported at both ends by slide rails on the top of the left and right parts of the gripping main frame 212. Each side of the gripping main frame 212 is also provided with a gripping horizontal moving rack 222 parallel to the slide rail. The moving frame 213 is provided with a mechanism for driving the moving frame 212. 13 A drive device that moves horizontally along the gripping horizontal moving rack 222. The vertical part of the moving frame 213 is provided with a gripping lifting frame 214 that moves up and down via a vertical slide rail. Vertical lifting gripping racks 215 are provided on both sides of the vertical part of the moving frame 213. The gripping lifting frame 214 is also provided with a drive device for driving the gripping lifting frame 214 to move up and down along the lifting gripping rack 215. The gripping lifting beam 209 is horizontally fixed on one side of the gripping lifting frame 214.

[0031] Specifically, the driving device of the mobile walking frame 213 includes a walking frame drive shaft 216 and a walking frame drive motor 217. The two ends of the walking frame drive shaft 216 pass through the plate-like structures at both ends of the same side of the mobile walking frame 213 and are fixed with walking frame drive gears 218. The walking frame drive gears 218 at each end mesh with the clamping horizontal moving racks 222 at each end. The walking frame drive motor 217 is fixed at the plate-like structure at one end of the mobile walking frame 213 and is connected to the walking frame drive shaft 216 through gears.

[0032] The driving device for the clamping lifting frame 214 includes a clamping frame drive shaft 219 and a clamping frame drive motor 220. The two ends of the clamping frame drive shaft 219 pass through the plate-like structures at both ends of the clamping lifting frame 214 on the same side and are fixed with clamping frame drive gears 221. The clamping frame drive gears 221 at each end mesh with the lifting clamping racks 215 at each end. The clamping frame drive motor 220 is fixed at the plate-like structure at one end of the clamping lifting frame 214 and is connected to the clamping frame drive shaft 219 through gears.

[0033] Working principle of this utility model: This utility model is part of an automatic glove-making device, and is installed on the top of an automatic glove-making device, above an alternating feeding structure. When the gloves on the alternating feeding structure (mechanism) are picked up and fed to the dynamic sorting mechanism, the specific working process is as follows:

[0034] The walking frame drive motor 217 rotates, driving the entire moving walking frame 213 to move upwards towards the alternating feeding structure (mechanism). Then, the clamping frame drive motor 220 drives the clamping lifting frame 214 downwards, causing each finger cylinder 201 to descend to correspond to each stack of gloves on the alternating feeding structure (mechanism). The finger cylinders 201 clamp the gloves, and because the outer end of the middle clamp 204 at the lower end of each finger cylinder 201 forms a clamping structure with the side clamping claw structures 202, double clamping can be achieved on the top layer of gloves in each area. This not only increases the clamping area and strengthens the clamping, but also improves the success rate of clamping. Additionally, photoelectric switches can be used, such as those on the glove placement area of ​​the alternating feeding structure (mechanism), or photoelectric switches with lights at the lower end of each finger cylinder 201. The purpose is to sense as the thickness of the stacked gloves decreases, and the clamping lifting frame 214 moves downwards accordingly. Furthermore, the elastic telescopic structure fixed at the upper end of the finger cylinders 201 also provides excellent clamping. The contact action allows the outer gripper 203 and the long strip gripper 205 to better contact the glove, thereby further improving the success rate of gripping. After the outer gripper 203 and the long strip gripper 205 grip the glove, the gripping frame drive motor 220 rotates in the reverse direction, driving the gripping lifting frame 214 to move upward. Then the walking frame drive motor 217 rotates in the reverse direction, driving the entire moving walking frame 213 away from the alternating feeding structure (mechanism) and moving above the dynamic sorting mechanism. The gripping frame drive motor 220 rotates forward again, driving the gripping lifting frame 214 to move downward, so that each finger cylinder 201 that grips the glove moves downward until it contacts the part of the dynamic sorting mechanism where the glove is placed. At this time, the finger cylinder 201 is controlled to release the outer gripper 203 and the long strip gripper 205, and the glove is placed on the part of the dynamic sorting mechanism where the glove is placed. Then, the gripping frame drive motor 220 and the walking frame drive motor 217 work in sequence to return to the alternating feeding structure (mechanism), and the above actions are repeated continuously to grip and feed the glove.

[0035] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
