Description

Technical Field

[0001] This invention relates to the field of elastic band processing technology, specifically to a multi-process integrated processing equipment for elastic band processing and its usage method. Background Technology

[0002] Elastic bands, as a type of elastic strip textile material, are widely used in clothing, underwear, bags, medical protective gear, and sports equipment to achieve functions such as cuffing, tightening, and comfortable fit. In the finished product processing of elastic bands, multiple process steps are usually required, such as feeding, fixed-length cutting (including end welding and sealing), sewing and connecting, and blanking, to process the continuous strip material into a loop-shaped finished product with a specific length and sewing structure. At present, the above processes are generally completed separately by single-function, modular equipment. That is, the semi-finished products from the previous process are transferred to the next machine for further processing by manual or semi-automatic means, forming a discrete production mode.

[0003] However, existing modular processing methods suffer from significant efficiency and quality issues in practical production applications. Firstly, the lack of automated coordination between individual machines necessitates frequent manual loading, positioning, and transfer operations, resulting in poor production continuity, high labor costs, and high labor intensity, making it difficult to meet the demands of large-scale continuous production. Secondly, traditional fixed-length cutting often employs mechanical cold or hot cutting methods, which easily produce burrs, loose lines, or weak edge sealing. Furthermore, cutting accuracy is greatly affected by manual operation, making consistency difficult to guarantee. Simultaneously, the lack of precise synchronous control between feeding and cutting actions further complicates matters. Elastic bands are prone to wrinkling and twisting during transport, and are susceptible to secondary deformation due to material stress and hardness. This can lead to stretching deformation or cutting position deviation. More importantly, existing equipment generally lacks online quality inspection methods, making it impossible to identify logos and detect defects in real time. This results in defective products (such as misaligned logos or poor printing) flowing into subsequent sewing processes, causing ineffective sewing and material waste, and a high defect rate. Therefore, this paper proposes a multi-process integrated processing equipment for elastic bands and its usage method to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-process integrated processing equipment for elastic band processing and its usage method, so as to solve the problems of poor process connection, low degree of automation, poor cutting accuracy and high defect rate caused by the inability to identify and remove waste online in existing elastic band processing equipment.

A drive cylinder is rotatably connected between the adapter head and the rear adapter seat. A feeding swing rod passing through the cover four is fixedly connected in the rod hole of the adapter head. The feeding swing rod is located on the lower side of the outward push part.

[0013] A preferred method of use includes the following steps: S1. Start-up and parameter setting: First, the elastic band is wound around the upper side of the anti-folding mechanism's belt-tapping wheel and between the upper and lower conveyor belts of the upper and lower conveyor sections. Then, the band is passed through the upper and lower conveyor sections and manually pulled through the guide roller group and the belt loop of the guide frame. Next, it passes through the guide roller frame of the transfer section and enters the upper guide. Then, it passes through the upper guide to the processing position of the ultrasonic cutter. Finally, the front end of the band is wound back to the waste discharge port of the lower guide and placed between the drive belt assembly and the pressure belt assembly. Then, the cutting length, sewing stitch length, heating temperature, and visual inspection parameters are input through the machine operation screen, vision operation screen, and sewing machine operation screen, respectively. The standard logo image is captured by the industrial camera of the vision camera mechanism to establish a recognition template. S2. Anti-crease and heated conveying: After starting the equipment, the motor of the drive unit starts running. Through the transmission of the synchronous pulley and synchronous belt, it drives the belt shaft and mating teeth on the left side of the lower conveyor to rotate, thereby starting the lower conveyor belt to run. At the same time, the motor drives the belt tapping wheel to rotate continuously. While pulling the belt body to the left, the tapping wheel uses the blades on its wheel to periodically strike the surface of the belt body, effectively preventing the belt body from wrinkling or creases during the conveying process. As the belt body enters the inner side of the second cover, the electric push rod begins to extend. Its lower end pushes the upper conveyor section downwards until the upper conveyor section moves to a position close to the lower conveyor section. At this time, the upper conveyor section... The mating teeth at the front end of the left belt shaft mesh with the mating teeth at the front end of the left belt shaft of the lower conveyor section. The rotational power of the lower conveyor section is transmitted to the upper conveyor section through the meshing teeth, driving the upper conveyor section to operate synchronously. This causes the conveyor belts of the upper and lower conveyor sections to run synchronously in opposite directions, clamping and conveying the belt body in the middle. During this process, the heating components installed inside the conveyor belt are activated synchronously. The heating plate heats the conveyor belt, and the heat is conducted to the belt body through the conveyor belt, achieving contact heating and softening of the belt body, reducing its stress and hardness, avoiding secondary deformation during the conveying process, and ensuring that the belt body is conveyed to the subsequent station to the left in a flat and soft state. S3. Visual Recognition and Synchronous Cutting: After passing through the conveyor section, the belt body enters the upper guide rail via the guide roller group, guide frame, and the steering transmission of the guide roller frame. The belt is continuously conveyed forward in the upper guide rail by the pusher assembly. When the belt body moves to the underside of the visual camera mechanism, the linear module two drives the mounting frame to move back and forth according to a preset program, adjusting the industrial camera to the optimal shooting position. Simultaneously, the supplementary lighting is turned on to provide uniform illumination. The industrial camera captures the logo on the belt surface in high definition and transmits the image data to the control system for verification against the preset recognition template. The visual inspection determines that the product is qualified. The pusher assembly continues to push the belt to the set length. Then the lower drive assembly starts and folds the belt down, so that the belt forms a folded ring structure and is sent to the cutting blade and ultrasonic head blade of the processing department. At this time, the telescopic cylinder drives the cutting blade to move backward through the connecting folding plate and the guide plate. At the same time, the ultrasonic transducer drives the ultrasonic head blade to generate high-frequency vibration. The cutting blade and the ultrasonic head blade work together to complete the fixed-length cutting of the folded belt and use ultrasonic energy to melt and solidify the cut edge to automatically seal the edge, thereby forming a fixed-length ring elastic band finished product. S4. Waste Discharge Processing: If visual inspection determines that the logo on the surface of the belt is misaligned, blurry, or poorly printed, the control system determines that the belt segment is a defective product. The belt drive assembly drives the defective belt segment to the lower guide, where it works in conjunction with the belt pressing assembly to clamp and position the waste belt and transport it downstream. Finally, the waste belt is discharged from the waste discharge port of the lower guide. After waste discharge is completed, the equipment automatically resets and enters the next working cycle. S5. Feeding and Sewing: For the qualified belt body that has been formed into a fixed-length ring structure through the aforementioned cutting process, the base of the linear module's first drive feeding mechanism moves to the left to the lower side of the processing section. At this time, the electrically controlled clamps at the front and rear positions on the left side of the base clamp and fix the two sides of the fixed-length ring elastic belt. Subsequently, the drive assembly on the left side starts and drives the electrically controlled clamps at the front and rear positions on that side to move backward along the guide rail, unfolding the ring elastic belt. Immediately afterwards, the linear module's first drive feeding mechanism continues to move to the left to the sewing machine on the left side. At the sewing station, the unfolded loop elastic band is placed on the sewing area of ​​the left sewing machine. The left sewing machine then starts and sews the molten section of the loop elastic band according to the preset stitch length parameters to strengthen the connection and form a loop-shaped finished elastic band. At the same time, the linear module drive base moves to the right and resets, transporting the next fixed-length loop elastic band synchronously processed by the ultrasonic cutter to the right sewing machine for sewing. This allows both sewing machines to simultaneously complete the double-sided stitching connection of the loop elastic band. S6. Automatic material collection: After the double-sided stitching is completed, the middle pusher and side pusher of the outer pusher unit work together to push the finished elastic band loop outward from the sewing area of ​​the sewing machine. The finished product falls and fits precisely on the outside of the material feeding swing arm of the material collection mechanism. Then, the drive cylinder is controlled to extend, and the drive adapter swings forward around the front adapter seat. The adapter drives the material feeding swing arm to swing forward synchronously, so that the position of the material feeding swing arm and the tape feeding mechanism are staggered to avoid the tape feeding mechanism that will approach the sewing machine later. After the tape feeding mechanism moves away from the sewing machine, the drive cylinder is controlled to retract in the opposite direction, driving the adapter and the material feeding swing arm to swing backward and reset, so that the material feeding swing arm returns to the initial receiving position, ready to receive the next finished product. S7. Continuous production: Under the unified control of the PLC control system, the equipment repeatedly executes steps S2 to S6, continuously performing the fully automated operation of anti-folding conveying, heating and softening, visual recognition detection, ultrasonic fixed-length cutting and forming, double-sided sewing reinforcement and automatic material collection, realizing the continuous and automated production of elastic band loop products until all processing tasks are completed or the operator issues a stop command through the machine operation screen.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, through the configuration of a feeding module, a transfer unit, a vision camera mechanism, an ultrasonic cutter holder, a belt feeding mechanism, a sewing machine, an outward pushing unit, and a receiving mechanism, the anti-wrinkle mechanism of the feeding module can flatten and shape the belt and prevent wrinkles during the initial conveying stage. The conveying unit of the feeding module can heat and soften the shaped belt and stabilize its conveying, reducing its stress and hardness, avoiding secondary deformation during conveying, and ensuring that the belt is conveyed to the subsequent workstation in a flat and soft state. Simultaneously, the vision camera mechanism can perform real-time identification and detection of the logo on the belt surface before cutting. Combined with the transfer unit and the ultrasonic cutter holder, this achieves… The current system automatically separates qualified products into fixed-length cuts and unqualified products, and the feeding mechanism can simultaneously send the formed ring-shaped belts to the sewing machines on both sides for synchronous sewing. Finally, the receiving mechanism automatically collects the finished products. This integrated processing equipment for elastic bands can perform anti-friction shaping, heating and softening, online logo recognition and automatic waste removal, ultrasonic fixed-length cutting and double-sided sewing in a continuous, automated and efficient manner. It solves the problems of poor process connection, low automation, poor cutting accuracy and high defect rate caused by the inability to identify and remove waste online, which are present in the existing separate processing equipment for elastic bands.

[0019] Workflow: The operating steps of the multi-process integrated processing equipment for elastic band processing are as follows: Start-up and parameter setting: First, the elastic band is wound around the upper side of the anti-bending mechanism 23's belt-tapping wheel 233 between the upper and lower conveyor belts 274 of the upper and lower conveyor sections 27. Then, the band is passed through the upper and lower conveyor sections 27, and manually pulled through the guide roller group 292 and the belt loop of the guide frame 293. Next, it passes through the guide roller frame 35 of the transfer section 3 and enters the upper guide channel 33. It then passes through the upper guide channel 33 to the processing position of the ultrasonic cutter holder 5. Finally, the front end of the band is wound back to the waste discharge port of the lower guide channel 34 and... It is located between the drive belt assembly 37 and the pressure belt assembly 38; then, the cutting length, sewing stitch length, heating temperature and visual inspection parameters are input through the machine operation screen 10, vision operation screen 14 and the operation screen on the sewing machine 7 respectively, and the standard logo image is captured by the industrial camera 44 of the vision camera assembly 4 to establish a recognition template; anti-please and heated conveying, after the equipment is started, the motor of the drive unit 24 starts to run, and through the transmission of the synchronous pulley and the synchronous belt, it drives the belt shaft 272 and the mating teeth 273 on the left side of the lower conveyor unit 27 to rotate, thereby making the lower conveyor belt 274 start to run; at the same time, the motor 232 The drive pulley 233 rotates continuously. While pulling the belt body to the left, the pulley 233 periodically strikes the surface of the belt body using blades on its wheel body, effectively preventing wrinkles or folds in the belt body during conveying. As the belt body enters the inner side of the housing 22, the electric push rod 26 begins to extend, and its lower end pushes the upper conveying section 27 downward until the upper conveying section 27 moves down to a position close to the lower conveying section 27. At this time, the mating teeth 273 at the front end of the left side shaft 272 of the upper conveying section 27 mesh with the mating teeth 273 at the front end of the left side shaft 272 of the lower conveying section 27. The rotational force is transmitted to the upper conveying section 27 through the meshing teeth 273, driving the upper conveying section 27 to operate synchronously, thereby making the conveyor belts 274 of the upper and lower conveying sections 27 run synchronously in opposite directions, clamping and conveying the belt body in the middle; during this process, the heating component 28 installed inside the conveyor belt 274 is started synchronously, the heating plate heats the conveyor belt 274, and the heat is conducted to the belt body through the conveyor belt 274, realizing contact heating and softening of the belt body, reducing its stress and hardness, avoiding secondary deformation during the conveying process, and ensuring that the belt body is conveyed to the subsequent station to the left in a flat and soft state;Visual recognition and synchronous cutting: After passing through the conveyor section 27, the belt portion is guided by the guide roller group 292, the guide belt frame 293, and the guide roller frame 35, and then enters the upper guide 33. The pusher assembly 51 drives the belt to continuously move forward in the upper guide 33. When the belt moves to the lower side of the visual camera mechanism 4, the linear module 41 drives the mounting frame 42 to move back and forth according to the preset program, adjusting the industrial camera 44 to the optimal shooting position. The supplementary light 43 is turned on simultaneously to provide uniform illumination. The industrial camera 44 takes a high-definition picture of the logo on the surface of the belt and transmits the image data to the control system for real-time comparison and analysis with the preset recognition template. If the visual inspection determines that it is a qualified product, the pusher assembly... Part 51 continues to push the belt body forward to the set length. Then, the lower drive assembly 52 starts and folds the belt body downward, forming a folded loop structure and sending it between the cutter 534 and the ultrasonic head cutter 536 in the processing section 53. At this time, the telescopic cylinder 531 drives the cutter 534 to move backward through the connecting folding plate 532 and the guide plate 533. At the same time, the ultrasonic transducer 535 drives the ultrasonic head cutter 536 to generate high-frequency vibration. The cutter 534 and the ultrasonic head cutter 536 cooperate to complete the fixed-length cutting of the folded belt body, and use ultrasonic energy to melt and solidify the cut edge for automatic sealing, thereby forming a fixed-length loop elastic band product. Waste disposal: If visual inspection determines that the logo on the surface of the belt body is misaligned, blurred, or printed... If defects such as poor brushing are found, the control system determines that the section of belt is defective. The drive assembly 37 drives the defective section of belt to the lower guide 34, where it works in conjunction with the pressing assembly 38 to clamp and position the waste belt and transport it downstream. Finally, the waste belt is discharged from the waste outlet of the lower guide 34. After waste discharge, the equipment automatically resets and enters the next work cycle. For feeding and sewing, for qualified belts that have formed a fixed-length ring structure after the aforementioned cutting process, the linear module 13 drives the base 61 of the feeding mechanism 6 to move to the left side of the processing section 53. At this time, the electrically controlled clamps 64 at the front and rear positions on the left side of the base 61 clamp and fix the two sides of the fixed-length ring elastic band. Then, the drive assembly 63 on the left side starts and drives the front side of the belt. The rear-positioned electronically controlled clamp 64 moves backward along the guide rail 62, unfolding the loop elastic band. Immediately afterwards, the linear module 13 drives the feeding mechanism 6 to continue moving to the left to the sewing station of the left sewing machine 7, placing the unfolded loop elastic band onto the sewing area of ​​the left sewing machine 7. Then, the left sewing machine 7 starts and sews and reinforces the molten section of the loop elastic band according to the preset stitch length parameters to improve the connection strength and form a loop-shaped finished product. At the same time, the linear module 13 drives the base 61 to move to the right and reset, transporting the next fixed-length loop elastic band synchronously processed by the ultrasonic cutter 5 to the right sewing machine 7 for sewing, so that both sewing machines 7 can simultaneously complete the double-sided stitching connection of the loop elastic band.After automatic material collection and double-sided sewing, the middle pusher 82 and side pusher 83 of the outward pusher 8 work together to push the sewn elastic band loop outward from the sewing area of ​​the sewing machine 7. The finished product falls and fits precisely on the outside of the material feeding swing arm 95 of the material collection mechanism 9. Then, the drive cylinder 94 is controlled to extend, and the drive adapter 93 swings forward around the front adapter seat 92. The adapter 93 drives the material feeding swing arm 95 to swing forward synchronously, so that the position of the material feeding swing arm 95 and the tape feeding mechanism 6 are staggered to avoid the tape feeding mechanism 6 that will subsequently approach the sewing machine 7. After the tape feeding mechanism 6 moves away from the sewing machine 7, then... The control cylinder 94 retracts in the reverse direction, causing the adapter 93 and the unloading swing arm 95 to swing backward and reset, returning the unloading swing arm 95 to its initial receiving position, ready to receive the next finished product. In continuous production, under the unified control of the PLC control system, the equipment repeatedly executes the above steps, continuously performing the fully automated process of anti-folding conveying, heating and softening, visual recognition detection, ultrasonic fixed-length cutting and forming, double-sided sewing reinforcement, and automatic material collection. This achieves continuous and automated production of elastic band loop products until all processing tasks are completed or the operator issues a stop command via the machine operation screen 10.

9. A method of use for a multi-process integrated processing equipment for elastic band processing as described in any one of claims 1 to 8, characterized in that, Includes the following steps: S1. Start-up and parameter setting: First, the elastic belt is wound around the upper side of the anti-bending mechanism (233) and onto the upper and lower conveyor belts (274) of the upper and lower conveyor sections (27). Then, the belt is passed through the upper and lower conveyor sections (27), and then manually pulled through the belt loops of the guide roller group (292) and the guide frame (293). Next, it passes through the guide roller frame (35) of the transfer section (3) and enters the upper guide track (33). The belt is passed to the processing position of the ultrasonic cutter holder (5), and finally the front end of the belt is wound back to the waste discharge port of the lower guide (34) and placed between the drive belt assembly (37) and the pressure belt assembly (38). Then, the cutting length, sewing stitch length, heating temperature and visual inspection parameters are input through the machine operation screen (10), vision operation screen (14) and the operation screen on the sewing machine (7), and the standard logo image is captured by the industrial camera (44) of the vision camera mechanism (4) to establish the recognition template. S2. Anti-folding and heated conveying: After the equipment is started, the motor of the drive unit (24) starts to run. Through the transmission of the synchronous pulley and the synchronous belt, it drives the belt shaft (272) and the mating teeth (273) on the left side of the lower conveyor unit (27) to rotate, thereby causing the lower conveyor belt (274) to start running. At the same time, the motor one (232) drives the belt tapping wheel (233) to rotate continuously. While pulling the belt body to the left, the belt tapping wheel (233) uses the blades on its wheel body to periodically hit the surface of the belt body, effectively preventing the belt body from wrinkling or folding during the conveying process. As the belt body enters the inner side of the cover two (22), the electric push rod (26) begins to extend. Its lower end pushes the upper conveyor unit (27) to move downward as a whole until the upper conveyor unit (27) moves down to a position close to the lower conveyor unit (27). At this time, the belt on the left side of the upper conveyor unit (27) starts to move downward. The mating teeth (273) at the front end of the shaft (272) mesh with the mating teeth (273) at the front end of the shaft (272) on the left side of the lower conveyor (27). The rotational force of the lower conveyor (27) is transmitted to the upper conveyor (27) through the meshing teeth (273), driving the upper conveyor (27) to run synchronously. This causes the conveyor belts (274) of the upper and lower conveyor sections (27) to run synchronously in opposite directions, forming a clamping and conveying of the belt body in the middle. During this process, the heating components (28) installed inside the conveyor belt (274) are started synchronously. The heating plate heats the conveyor belt (274), and the heat is conducted to the belt body through the conveyor belt (274), achieving contact heating and softening of the belt body, reducing its stress and hardness, avoiding secondary deformation during the conveying process, and ensuring that the belt body is conveyed to the subsequent work station to the left in a flat and soft state. S3. Visual recognition and synchronous cutting: After passing through the conveyor section (27), the belt body enters the upper guide rail (33) after being guided by the guide roller group (292), the guide belt frame (293), and the guide roller frame (35). The belt body is continuously conveyed forward in the upper guide rail (33) by the pusher assembly (51). When the belt body moves forward to the lower side of the visual camera mechanism (4), the linear module two (41) drives the mounting frame (42) to move in the front and back direction according to the preset program, adjusts the industrial camera (44) to the best shooting position, and the supplementary light (43) is turned on at the same time to provide uniform illumination. The industrial camera (44) takes a high-definition picture of the logo on the surface of the belt body and transmits the image data to the control system for real-time comparison with the preset recognition template. Analysis; If the visual inspection determines that it is a qualified product, the pusher assembly (51) continues to push the belt body forward to the set length, and then the lower drive assembly (52) starts and folds the belt body down, so that the belt body forms a folded ring structure and is sent to the cutting blade (534) and ultrasonic head blade (536) of the processing part (53). At this time, the telescopic cylinder (531) drives the cutting blade (534) to move backward through the connecting folding plate (532) and the guide plate (533). At the same time, the ultrasonic transducer (535) drives the ultrasonic head blade (536) to generate high frequency vibration. The cutting blade (534) and the ultrasonic head blade (536) cooperate to complete the fixed length cutting of the folded belt body, and use ultrasonic energy to melt and solidify the cut edge to automatically seal the edge, thereby forming a fixed length ring elastic band finished product. S4. Waste discharge treatment: If visual inspection determines that the logo on the surface of the belt is misaligned, blurred or poorly printed, the control system determines that the belt segment is a defective product. The belt drive assembly (37) drives the defective belt segment to the lower guide (34), and cooperates with the belt pressing assembly (38) to clamp and position the waste belt and transport it downstream. Finally, the waste belt is discharged from the waste discharge port of the lower guide (34). After the waste discharge is completed, the equipment automatically resets and enters the next working cycle. S5. Feeding and sewing: For the qualified belt body that has formed a fixed-length ring structure after the aforementioned cutting process, the base (61) of the linear module one (13) drives the belt feeding mechanism (6) to move to the left side to the lower side of the processing section (53). At this time, the electric control clamps (64) at the front and rear positions on the left side of the base (61) clamp and fix the belt body on both sides of the fixed-length ring elastic band. Then, the drive assembly (63) on the left side starts and drives the electric control clamps (64) at the front and rear positions on that side to move backward along the guide rail (62) to unfold the ring elastic band. Immediately afterwards, the linear module one (13) drives the belt feeding mechanism (6) to continue to move to the left side. At the sewing station of the left sewing machine (7), the unfolded loop elastic band is placed in the sewing area of ​​the left sewing machine (7). Then the left sewing machine (7) starts and sewing reinforces the molten section of the loop elastic band according to the preset stitch length parameters to improve the connection strength and form a loop elastic band finished product. At the same time, the linear module 1 (13) drives the base (61) to move to the right and reset, and transports the next fixed-length loop elastic band processed by the ultrasonic cutter (5) to the right sewing machine (7) for sewing, so that the two sewing machines (7) can simultaneously complete the double-sided stitching connection of the loop elastic band. S6. Automatic material collection: After the double-sided stitching is completed, the middle pusher (82) and the side pusher (83) of the outer pusher (8) work together to push the finished elastic band loop outward from the sewing area of ​​the sewing machine (7). The finished product falls and fits precisely on the outside of the material collection mechanism (9)'s feeding swing rod (95). Then, the drive cylinder (94) is controlled to extend, and the drive adapter (93) swings forward around the front adapter seat (92). The adapter (93) carries... The material feeding lever (95) swings forward synchronously, so that the positions of the material feeding lever (95) and the tape feeding mechanism (6) are staggered to avoid the tape feeding mechanism (6) that is approaching the sewing machine (7) later; after the tape feeding mechanism (6) moves away from the sewing machine (7), the drive cylinder (94) is controlled to retract in the opposite direction, driving the adapter (93) and the material feeding lever (95) to swing backward and reset, so that the material feeding lever (95) returns to the initial receiving position, ready to receive the next finished product; S7. Continuous production: Under the unified control of the PLC control system, the equipment repeatedly executes steps S2 to S6, continuously carrying out the full-process automated operation of anti-folding conveying, heating and softening, visual recognition detection, ultrasonic fixed-length cutting and forming, double-sided sewing reinforcement and automatic material collection, so as to realize the continuous and automated production of elastic band ring-shaped finished products until all processing tasks are completed or the operator issues a stop command through the machine operation screen (10).
