Description

Technical Field

[0001] The present invention relates to the technical field of abdominal pad production equipment, and more particularly to an abdominal pad processing system. Background Art

[0002] During human surgery, medical personnel need to use abdominal pads to wipe the blood on the surgical incision and surgical instruments to facilitate the visualization of relevant parts of the human body and perform the surgery accurately. Therefore, the demand for this type of pads in hospitals is increasing year by year, and the efficiency of manufacturers needs to be improved along with the demand. At present, the production process of abdominal pads has been replaced by automated production. The automated production equipment must include a conveying mechanism, a folding mechanism, and a sewing mechanism.

[0003] At present, the abdominal pad fabric is sequentially cut, folded, loaded with label and sewn during the production process. However, there are two existing production methods. One is the traditional manual production, in which the abdominal pad fabric is folded in half, stacked, and then quantitatively cut through a size plate, and then the label is manually placed at the positioning point, and finally sewn. This method is prone to uneven stacking, resulting in skewed cutting edges, inconsistent cutting sizes of the middle and lower abdominal pad fabrics, inaccurate label placement, and low sewing efficiency; the other is automated production, in which the abdominal pad fabric is conveyed to the bottom of the cutting knife through a conveyor roller, and the length of the abdominal pad fabric conveyed is calculated by the number of rotations of the conveyor roller, or by a fixed position in front of the cutter. The position is determined to determine whether the length of the abdominal pad fabric meets the requirement, and then the cotton tape is conveyed horizontally by a conveyor belt, and then a shell conveyor line is added above the cotton tape, and a certain amount of the shell and a certain amount of the cotton tape are cut and welded by ultrasonic wave. After completion, the welded label tape is directly clamped by a robot and one side is aligned and placed on the abdominal pad fabric for sewing. Finally, the other side of the cotton tape is folded in half by a robot and sewn. After the folded edge is sewn, it is conveyed to the collection box by a conveyor belt. This production method is limited to quantitative cutting of a shorter length, and the folding efficiency is low due to folding in half after quantitative cutting, the production efficiency of the label tape and the sewing efficiency with the abdominal pad are low, and neat stacking cannot be achieved after sewing.

[0026] The beneficial effects of the present invention are as follows: 1. Through the cooperation between the upper folding plate and the folding plate, the upper folding plate first clamps and lifts the head end of the output fabric, and then the folding plate moves in the conveying direction of the output fabric so that the folding plate pushes the lifted output fabric to one side of the conveying direction, thereby folding the output fabric in half. Compared with the existing quantitative cutting mechanism, this method can arbitrarily select the required abdominal pad length according to needs, avoiding the problem that the required abdominal pad length is too long and the working platform is insufficient to meet the required length;

[0027] 2. Through the cooperation of the upper folding plate, the lower folding plate and the pressing sheet, the upper folding plate first clamps the head end of the output fabric, and the side edge of the head end of the output fabric can be folded through the first clamping groove. After the output fabric is lifted by the upper folding plate, the folding plate is quantitatively folded and cut. Then, the lower folding plate clamps the output fabric, and the side edge of the cut end of the output fabric can be folded through the second clamping groove. After the head end is folded, it is aligned and superimposed on the folded edge of the cut end. Compared with the existing folding mechanism, this method combines the folding edges together during the quantitative process, so that the coordination between the various mechanism components is higher, the volume of the equipment is reduced, the efficiency of quantitative folding, cutting and folding is improved, and the production efficiency of the abdominal pad is greatly improved;

[0028] 3. A shifting mechanism is provided on both sides of the pressing plate. The two corners of the folded edge are shifted inwards by the shifting pieces in the shifting mechanism. The purpose of this process is to prevent the corners from overflowing during the folding and sewing process, resulting in incomplete sewing of the corners or uneven side sewing, which ultimately reduces the production yield.

[0029] 4. The cotton tape enters the welding table from the top, and the rubber strip enters the welding table from the bottom. The rubber strip and the cotton tape are welded by ultrasonic welding. The cotton tape is fixed in the specified position by the cotton tape positioning component. Even after the cotton tape is cut, the cotton tape will not be pulled out of the cotton tape positioning component to prevent the cotton tape from being separated and unable to be subsequently transported. After the rubber strip is cut, the rubber strip is pressed into the corresponding groove of the welding table by the pressing block to prevent the rubber strip from being separated from the welding table and unable to be subsequently transported and welded.

[0030] 5. Through the cooperation of multiple components, the cotton tape can be folded in half in a fixed amount and then sewn with a fixed amount of rubber strips before being cut. The two free ends of the cotton tape, which has been welded, cut and folded in half, are then clamped by the tape picking and delivering component and transferred to the abdominal pad of the fixed-length folding device. The abdominal pad placement component clamps the abdominal pad to the clamping mechanism and transfers it to the sewing machine for sewing. This method allows the fixed amount of folding and welding of the tape to be carried out in the same continuous process, and the work efficiency is high. The loading process of the tape eliminates the need for the sewing mechanism to sew twice. The two free ends of the tape are aligned and placed on the folded edge of the abdominal pad during the transfer process, saving placement time and thus saving working time.

[0031] 6. Two sets of clamping arms move to the hemming processing device to clamp the belly pad after the hems are folded and the label tape is loaded, and then transfer it to the sewing platform for sewing. During the clamping process, the two sets of clamping arms always accurately and stably clamp the two hems of the belly pad, preventing the two hems from falling off or shifting during the transfer process, which would affect the subsequent sewing. In other words, the setting of two sets of clamping arms can improve the efficiency of belly pad transportation and increase the pass rate of belly pads;

[0032] 7. The sewn belly pad is pressed into the pressurized space between the two vertical plates by the transfer mechanism. The belly pad pressed into the pressurized space is prevented from falling off by the clamping of the two vertical plates. The belly pad is transferred to the material receiving door by the transfer mechanism. The material picking mechanism presses the belly pad downward to separate from the material receiving door. The material receiving door is opened by pressing, and the belly pads on the material receiving door fall down stably and neatly and are stacked in the collection box.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0054] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0055] The present invention designs this abdominal pad processing system, and the specific mechanism is as follows Figure 1-17As shown, it includes a fixed-length folding device 1, a label placement device 2 and a sewing device 3. The label placement device 2 and the sewing device 3 are respectively located on both sides of the discharge port of the fixed-length straight edge device. The fixed-length folding device 1 includes a fixed-length frame 101, and the fixed-length frame 101 includes a working platform, a cutting mechanism 103 and an abdominal pad material roll 102. The cutting mechanism 103 is located above the working platform and is used to cut the output fabric of the abdominal pad material roll 102. The label placement device 2 includes a placement frame, and the placement frame is provided with a welding table 251, a cotton tape roller 249, and an adhesive label roller 2 14. An ultrasonic welding mechanism 250 and a label placement mechanism 202. The cotton tape roller 249 is provided with a cotton tape roll, and the adhesive label roller 214 is provided with an adhesive label roll. The output cotton tape of the cotton tape roll and the output adhesive label of the adhesive label roll pass through the ultrasonic welding mechanism 250 at the same time. The ultrasonic welding mechanism 250 is used to ultrasonically weld the output cotton tape and the output adhesive label. The sewing equipment 3 includes a sewing machine frame 301. The sewing machine 302 is provided on the sewing machine frame 301. The sewing machine 302 is used to sew the abdominal pad after the label is loaded. The above is an indispensable mechanism in the currently available abdominal pad processing equipment.

[0056] There are two existing quantitative cutting and folding methods. One is traditional manual production, in which the abdominal pad fabric is folded and then quantitatively cut through a size plate. This quantitative cutting is prone to uneven superposition, resulting in skewed cutting edges, and inconsistent cutting sizes of the middle and lower abdominal pad fabrics. The other is automated production, in which the abdominal pad fabric is conveyed to the bottom of the cutting knife through a conveyor roller, and the length of the abdominal pad fabric conveyed is calculated by the number of rotations of the conveyor roller, or the length of the abdominal pad fabric is determined to meet the requirements by the positioning point in front of the cutting knife. The folding mechanism 112 of the abdominal pad fabric is relatively complex and needs to be realized through the linkage of multiple parts. This quantitative cutting is only suitable for cutting of shorter lengths, and the folding efficiency of this folding method is low, and automated and rapid production cannot be achieved. Therefore, in order to solve this problem, Figure 2 As shown, the fixed-length frame 101 also includes a folding mechanism and a folding mechanism 112. The folding mechanism includes a folding plate 110 and a first folding power source 111 (motor). The folding plate 110 is located on the upper surface of the working platform. Figure 3-6As shown, the folding mechanism 112 includes an upper folding plate 113, a lower folding plate 116, a pressing plate 118, a second folding power source 120 (cylinder), a third folding power source 121 (cylinder), a first rotary power source 122 (motor) and a second rotary power source 123 (motor). The upper folding plate 113 and the lower folding plate 116 are both located below one side of the working platform (this side is the side of the output fabric outlet, that is, the end of the working platform), and the upper folding plate 113 is located above the lower folding plate 116, the pressing plate 118 is located above the working platform, and the upper folding plate 113 and the lower folding plate 116 are respectively provided with a first slot 114 and a second slot 117. When the conveying fabric is transported to the top of the folding upper clamping plate 113, the second folding power source 120 drives the pressing plate 118 to move in the vertical direction so that the pressing plate 118 presses one side of the output fabric into the first slot 114 (at this time, one side of the output fabric is not aligned with the first slot 114, so the edge will form a fold after being inserted into the first slot 114 through the pressing plate 118). The third folding power source 121 drives the folding upper clamping plate 113 to move in the vertical direction so that the folding upper clamping plate 113 lifts one side of the clamped output fabric upward to the top of the working platform. The first rotary power drives the folding upper clamping plate 113 to rotate in the vertical direction so that the folding upper clamping plate 113 rotates one side of the clamped output fabric to be parallel to the working platform, and the first folding power source 111 drives the folding plate 110 to move in the horizontal direction so that the folding plate 110 pushes the lifted output fabric to one side, and the movement direction of the folding plate 110 is the same as the conveying direction of the output fabric (through the cooperation of the upper folding clamping plate 113 and the folding plate 110, the head end of the output fabric is first clamped and lifted by the upper folding clamping plate 113, and then the folding plate 110 moves in the conveying direction of the output fabric so that the folding plate 110 pushes the lifted output fabric to one side of the conveying direction, so that the output fabric can be folded in half. Compared with the existing quantitative cutting mechanism 103, this method can be arbitrarily selected according to needs Select the required abdominal pad length to avoid the problem that the required abdominal pad length is too long and the working platform is not sufficient to meet the required length). When the cutting mechanism 103 cuts the output fabric, the second translational power source 325 drives the pressing plate 118 to move in the vertical direction, so that the pressing plate 118 presses the side edge of the output fabric cut into the second slot 117. The second rotational power source 123 drives the lower folding clamping plate 116 to rotate in the vertical direction, so that the lower folding clamping plate 116 rotates the clamped side edge of the output fabric to be parallel to the working platform. The rotation direction of the upper folding clamping plate 113 is the same as that of the lower folding clamping plate 116, and both rotate toward the side of the abdominal pad fabric roll 102.Through the cooperation of the upper folding clamping plate 113, the lower folding clamping plate 116, and the pressing plate 118, the upper folding clamping plate 113 first clamps the head end of the output fabric, and the side edge of the head end of the output fabric can be folded through the first clamping groove. After the output fabric is lifted by the upper clamping plate, the folding plate 110 folds and cuts the output fabric in a predetermined amount. During the process of predetermined amount folding and lifting, it stops, and the middle of the output fabric is opened, allowing the pick-up and delivery hand to insert the label tape into the fold from one side. The output fabric is then clamped by the lower clamping plate, and the side edge of the cut end of the output fabric can be folded through the second clamping groove. After the head end is folded, it is aligned and superimposed on the folded edge of the cut end. Compared with the existing folding mechanism 112, this method combines the folding edges together during the predetermined amount process, making the coordination between the various mechanism components higher, reducing the volume of the equipment, and improving the efficiency of the predetermined amount folding, cutting, and folding work, thereby greatly improving the production efficiency of the abdominal pad.

[0057] Since the current abdominal pad fabric needs to place a label at a certain folded edge during the production process, the label is composed of a shell sheet and a surface tape superimposed on each other. The function of the label is to prevent the abdominal pad from being missed in the patient's body during surgery and causing secondary damage. There are two ways to produce and load the existing label, one is manual production, and the other is automatic production. The automatic production is to convey the cotton tape horizontally through a conveyor belt, and then add a shell sheet conveyor line above the cotton tape, cut a certain amount of shell sheet and a certain amount of cotton tape and weld them by ultrasonic welding. After completion, the welded label is directly clamped by a robot and one side is aligned and placed on the abdominal pad fabric for sewing. Finally, the other side of the cotton tape is folded in half by the robot and sewn. Although this method replaces manual work through automation, this kind of automated production is prone to slow label production efficiency, and its label loading efficiency is prone to low, and when the label is placed on the abdominal pad, it needs the cooperation of the sewing machine 302 mechanism, and sewing needs to be sewn twice, so the label production and loading are relatively time-consuming; so in order to solve this problem, Figure 9-14 As shown, the label placement mechanism 202 also includes a cotton ribbon pulling component 203, a cotton ribbon guiding component 206, a first cutting component 210, a second cutting component 213, a label picking and delivering component 216 and an abdominal pad placement component 226. The output cotton ribbon is located on one side of the welding table 251 and is transported in the vertical direction. One end of the output adhesive label is located on the welding table 251 and is transported in the horizontal direction (the output cotton ribbon is transported from top to bottom, the output adhesive label is transported from bottom to top and then transported horizontally to the welding table 251, and the output cotton ribbon is pushed into the welding table 251 through a guide push rod 207. Compared with the prior art, both of them directly enter the welding table 251 in the horizontal direction, and the purpose of folding the cotton ribbon in half before welding cannot be achieved). Figure 11As shown, the cotton tape pulling assembly 203 includes a positioning clamp 204 and a pulling power source 205 (cylinder). The positioning clamp 204 is located below the initial end of the output cotton tape. The label tape placement mechanism 202 also includes a cotton tape positioning assembly 240. The cotton tape positioning assembly 240 includes a cotton tape positioning seat 241, a guide plate 243, a baffle 245, a first guide column 246 and a second guide column 247. A conveying groove 244 is provided on one side of the cotton tape positioning seat 241. The guide plate 243 is tilted on the cotton tape positioning seat 241. A plurality of side-by-side limit buckles are provided on one side of the guide plate 243. The plurality of limit buckles are connected to the output The delivery trough 244 is on the opposite side, the baffle 245 is located on the cotton tape positioning seat 241 on one side of the delivery trough 244, the first guide column 246 is located below the baffle 245 and above the first cutting knife 211, the first cutting knife 211 is horizontally located between the first guide column 246 and the second guide column 247, the second guide column 247 is located below the first cutting knife 211, and a second telescopic cylinder 248 is further provided on one side of the second guide column 247 to drive the second guide column 247 to move on the horizontal plane. The output cotton tape passes through the limit buckle and the delivery trough 244 in sequence, and the output cotton tape is respectively wound around the first guide column 246 and the second guide column 247. 6 and the second guide column 247, the pulling power source 205 drives the positioning clamp 204 to move in the vertical direction, so that the initial end of the output cotton belt falls into or out of the positioning clamp 204, and the positioning clamp 204 is used to clamp or separate the initial end of the output cotton belt; the process is as follows: the output cotton belt enters the multiple limit buckles of the guide plate 243 from the top, and then enters the conveying trough 244, and is output from the bottom end of the conveying trough 244 to between the first guide column 246 and the second guide column 247, wherein it passes through the first cutting knife 211, and the pulling power source 205 drives the positioning clamp 204 to move upward to clamp the initial end of the output cotton belt. Pull it downwards. At this time, the output cotton tape is still being transported, and then it is folded in half under the action of the subsequent cotton tape guide assembly 206. When a certain requirement is met, the first cutting knife 211 cuts the output cotton tape, and the output cotton tape stops being transported at this time. After being cut, the upper head of the output cotton tape becomes the new starting end. The setting of the limit buckle, conveying groove 244, baffle 245, first guide column 246 and second guide column 247 has an additional guide limit effect compared to the existing direct transmission mechanism, and the first guide column 246 can move in the horizontal direction. Its purpose is to tighten or loosen the output cotton tape, which plays an auxiliary role in the subsequent quantitative folding.

[0058] like Figure 11As shown, the cotton tape guide assembly 206 includes a guide push rod 207, a first telescopic cylinder 208 and a guide power source 209 (cylinder). The guide push rod 207 is located on one side of the welding table 251. Since the cotton tape needs to be folded in half when sewing it to the abdominal pad, and the two free ends are sewing ends, in order to improve the production efficiency of the label tape, the cotton tape is quantitatively folded in half before the adhesive label is welded. The means is that the first telescopic cylinder 208 drives the guide push rod 207 to move on the horizontal plane, so that the guide push rod 207 is pushed to the side of the output cotton tape after the positioning clamp 204 pulls and positions it, and the guide power source 209 drives the guide push rod 207 to move on the horizontal plane, so that the guide push rod 207 is pressed against one side of the output cotton tape and pushes the output cotton tape toward the welding table 251. The effect is that the cotton tape can be folded to different lengths as required. Compared with the conveyor belt transmission quantitative cutting in the prior art, the quantitative length selectivity of the method in the present invention is higher.

[0059] like Figure 10 As shown, the first cutting assembly 210 includes a first cutting knife 211 and a first cutting power source 212. The first cutting knife 211 is located above one side of the welding table 251, and the output cotton strip is located within the blade of the first cutting knife 211. The first cutting power source 212 drives the first cutting knife 211 to move on a horizontal plane so that the first cutting knife 211 cuts the output cotton strip; Figure 11 As shown, the second cutting assembly 213 includes a second cutting knife and a second cutting power source. The second cutting knife is located on the side of the welding platform 251 in the pushing direction of the guide push rod 207. The folded output cotton strip after the glue label is superimposed and welded is located in the blade of the second cutting knife. The second cutting power source drives the second cutting knife to move in the vertical direction so that the second cutting knife cuts the folded output cotton strip after the glue label is superimposed and welded.

[0060] like Figure 14As shown, the label tape picking and delivering assembly 216 includes a picking and delivering hand, a first picking and delivering power source 218 (cylinder) and a second picking and delivering power source 225 (cylinder). The first picking and delivering power source 218 drives the picking and delivering hand to move on the horizontal plane so that the picking and delivering hand is aligned with the welded label tape (the picking and delivering slide rail 224 is horizontally laid on one side of the welding table 251 along the movement direction of the guide push rod 207, the slide 223 is slidably set on the picking and delivering slide rail 224, and the vertical slide 223 is set at one end of the slide 223, that is, the first picking and delivering power source 218 drives the slide 223 to move on the picking and delivering slide rail 224, that is, the vertical slide rail 217 moves in the horizontal direction, that is, the picking and delivering hand moves in the horizontal direction). The picking and delivering hand is used to clamp the welded label tape, and the second picking and delivering power source 225 drives the picking and delivering hand to move in the horizontal direction. The delivery hand moves in the vertical direction so that the picking-up hand can transfer the clamped label to the side of the discharge port of the fixed-length folding device 1 (that is, the picking-up hand moves on the vertical slide rail 217). The label picking-up assembly 216 also includes a picking-up slide rail 224, a slide 223 and a vertical slide rail 217. The picking-up slide rail 224 is horizontally laid on one side of the welding table 251 along the movement direction of the guide push rod 207. The slide 223 is slidably set on the picking-up slide rail 224. The vertical slide rail 217 is set at one end of the slide 223. The picking-up hand includes a support seat 219, an upper picking-up splint 220, a lower picking-up splint, a fourth telescopic cylinder and a fifth telescopic cylinder. The support seat 219 is slidably set on the vertical slide rail 217. The upper picking-up splint 220, the lower picking-up splint and the fifth telescopic cylinder are The cylinders are all located on the support seat 219. The fourth telescopic cylinder drives the support seat 219 to move in the horizontal direction so that the label tape clamped between the upper and lower splints 220 and the pick-up and delivery is transferred to the side of the folded abdominal pad of the fixed-length folding device 1. The fifth telescopic cylinder drives the upper and lower splints 220 to move in the vertical direction so that the upper and lower splints 220 are pressed down or separated from the pick-up and delivery lower splint. The upper and lower splints 220 and the lower splint are both provided with a first protrusion 221 and a second protrusion 222 on the same side (the first protrusion 221 and the second protrusion 222 are both strip-shaped, and both face the side of the folded label tape). The first protrusion 221 of the upper and lower splints 220 cooperates with the first protrusion 221 of the lower splint to clamp the upper and lower splints 220. The two protrusions 222 cooperate with the second protrusion 222 of the picking and delivering lower clamping plate to clamp the label. The process is as follows: after the label is folded, welded and cut, the cylinder drives the slide 223 to move on the picking and delivering slide rail 224, so that the first protrusion 221 and the second protrusion 222 of the picking and delivering hand clamp the two aligned free ends of the label. After clamping, the cylinder drives the slide 223 to move to one side so that the picking and delivering hand moves to one side of the working platform, and the cylinder drives the picking and delivering hand to move on the vertical slide rail 217. Compared with the picking and delivering hand in the prior art, the picking and delivering hand in the present invention can accurately clamp the two aligned free ends of the folded and welded label, and can stably transfer the folded part of the abdominal pad of the fixed-length folding device 1 after being clamped by the first protrusion 221 and the second protrusion 222.Avoid the two aligned free ends from being separated or shifted during the transfer process.

[0061] like Figure 14 As shown, the abdominal pad placement assembly 226 includes a placement hand 227, a first placement power source 231 and a second placement power source 232. The first placement power source 231 drives the placement hand 227 to move in the vertical direction so that the placement hand 227 and the fixed-length folding device 1 are on the same plane. The second placement power source 232 drives the placement hand 227 to move in the horizontal plane so that the placement hand 227 moves to the discharge port of the fixed-length folding device 1. The placement hand 227 is used to clamp the abdominal pad after the fixed-length folding device 1 is loaded with the label. The placement hand 227 includes an upper clamping strip 228, a lower clamping strip and a sixth clamping strip. The telescopic cylinder 230, the upper clamp 228 and the lower clamp are provided with a matching notch 229 on the same side (the upper clamp 228 and the lower clamp in the present invention are both strip-shaped), the sixth telescopic cylinder 230 drives the upper clamp 228 to move in the vertical direction so that the upper clamp 228 acts on the lower clamp, and the process is: when the abdominal pad label of the fixed-length folding device 1 is loaded and the folding is completed, the placement hand 227 is driven by the cylinder to the discharge port of the fixed-length folding device 1 to clamp the abdominal pad, and after clamping, it returns to its original position, and the clamping mechanism 304 of the sewing device 3 moves forward, and the clamping arm 306 on one side can be extended into the matching notch 229 to clamp the abdominal pad.

[0062] Since the current abdominal pad needs to be folded first, then labeled, and finally sewn during the production process, it is well known that a complete and qualified abdominal pad has two or more layers. It can be a single abdominal pad folded in half and then sewn, or multiple abdominal pads stacked and then sewn. There are two existing sewing methods. One is traditional manual production, in which the abdominal pad with folded edges and labeled is manually pushed into the sewing machine 302 for pedal sewing. This sewing method is prone to problems such as uneven sewing and low sewing efficiency. The other is automated production. During production, the belly pad with folded edges and labeled tape is transported to the bottom of the sewing machine 302 group by a transfer hand or a conveyor belt, and then the belly pad is pulled by a pulling hand on one side for trial sewing. After sewing, it is transported to a collection box by a conveyor belt. This sewing method is prone to position deviation during the transmission process, resulting in uneven subsequent sewing. Moreover, after sewing is completed, the belly pad cannot be neatly stacked by directly transporting it by the conveyor belt, resulting in the finished product being too large for subsequent manual picking up, and causing low production efficiency, and problems such as too high finished products. In order to solve this problem, Figure 15As shown, the sewing machine frame 301 also includes a clamping mechanism 304, a transfer mechanism 315 and a picking mechanism 322, and the transfer mechanism 315 is located between the clamping mechanism 304 and the picking mechanism 322 (the sewing machine frame 301 of the present invention has two groups, one group is used to carry the sewing machine 302 and the clamping mechanism 304, and the other group is used to carry the transfer mechanism 315 and the picking mechanism 322, and the two groups are arranged side by side). Figure 16 As shown, the clamping mechanism 304 includes a beam 305 and two groups of clamping arms 306. The beam 305 is horizontally located on the sewing platform 303. The two groups of clamping arms 306 are horizontally arranged on the same side of the beam 305, and the two groups of clamping arms 306 are perpendicular to the beam 305. A first translational power source 314 is also provided on one side of any group of clamping arms 306. The first translational power source 314 drives the group of clamping arms 306 to move on the horizontal plane so that the group of clamping arms 306 calibrates the corresponding folding edges of the abdominal pad on the folding processing device. A second translational power source 325 is provided on one side of the beam 305. The second translational power source 325 drives the beam 305 to move on the horizontal plane so that the two groups The clamping arms 306 move close to or away from the abdominal pad after the label tape is loaded and folded on the folding processing device. The two sets of clamping arms 306 are used to clamp the abdominal pad after the label tape is loaded and folded on the folding processing device; its beneficial effect is: the two sets of clamping arms 306 move to the side of the placement hand 227 to clamp the abdominal pad after the folding and label tape is loaded and transfer it to the sewing platform 303 for sewing. During the clamping process, the two sets of clamping arms 306 always clamp the two folded edges of the abdominal pad accurately and stably to avoid the two folded edges falling off or shifting during the transfer process, thereby affecting the subsequent sewing. That is, the setting of the two sets of clamping arms 306 can improve the transportation efficiency of the abdominal pad and improve the pass rate of the abdominal pad.

[0063] like Figure 17As shown, the transfer mechanism 315 includes a slide plate 316, an upper pressure plate 130 and two vertical plates 317. The upper pressure plate 130 and the two vertical plates 317 are all located at the bottom of the slide plate 316. The two vertical plates 317 are arranged horizontally with each other, and there is a pressurized space 326 between the two vertical plates 317 (the pressurized space 326 here refers to the distance between the two vertical plates 317). The upper pressure plate 130 is located directly above the pressurized space 326. The slide plate 316 is provided with a third translational force source 318. (motor) and the fourth translational power source 319 (cylinder), the third translational power source 318 drives the slide 316 to move in the horizontal direction so that the upper pressing plate 130 is located above the belly pad between the clamping arm 306 and the sewing platform 303, and the pressurized space 326 is located below the belly pad between the clamping arm 306 and the sewing platform 303 (in this solution, the transfer mechanism 315 also includes a horizontally laid conveyor belt located above the receiving door 327, and the slide 316 is connected to the conveyor belt , one end of the conveyor belt extends above the clamping mechanism 304, and the motor rotates to drive the conveyor belt to move, that is, the slide 316 follows the conveyor belt movement), and the fourth translational power source 319 drives the upper pressing plate 130 to move in the vertical direction, so that the upper pressing plate 130 presses the abdominal pad between the clamping arm 306 and the sewing platform 303 into the pressurized space 326; the upper pressing plate 130 is an inverted L-shape, and the upper pressing plate 130 includes a horizontal pressing portion 320 and a vertical insertion portion 321, and the vertical insertion portion 321 A limit plate 328 parallel to the horizontal pressing part 320 is provided on the inner side surface, and a sliding column 329 is provided between the limit plate 328 and the horizontal low-pressure part, and a buffer spring is provided on the sliding column 329 (the buffer spring plays a buffering role to prevent the upper pressure plate 130 from being hit by excessive force on the limit plate 328); a sixth translational motive force source (cylinder) is provided on any vertical plate 317, and the sixth translational motive force source drives any vertical plate 317 to move on the horizontal plane to increase the pressurized space 326.

[0064] like Figure 15As shown, the material picking mechanism 322 includes multiple groups of pressing rods 323, and a material receiving door 327 is provided on the base on one side of the sewing machine 302 (the material receiving door 327 in the present invention is two door panels hinged on the sewing machine frame 301 on the opposite sides, similar to an old-fashioned window), multiple groups of pressing rods 323 are symmetrically arranged on both sides of the movement track of the slide plate 316, and multiple groups of pressing rods 323 are all located above the material receiving door 327 (the distance between the two pressing rods 323 opposite to each other on both sides of the movement track of the slide plate 316 is greater than the width of the abdominal pad, so that the pressing rods 323 are not directly pressed on the abdominal pad when pressing), and corresponding pressing cylinders 324 are respectively provided on the multiple groups of pressing rods 323, which drive the pressing rods 323 to move. 23 moves in the vertical direction so that the pressing rod 323 presses the material receiving door 327 to open and the abdominal pad located above the material receiving door 327 falls down, which has the beneficial effect of: the abdominal pad after sewing is pressed into the pressurized space 326 between the two vertical plates 317 by the transfer mechanism 315, and the abdominal pad pressed into the pressurized space 326 is prevented from falling off by the clamping of the two vertical plates 317, and is transferred to the material receiving door 327 by the transfer mechanism 315, and the vertical plates 317 are pressed downward by the picking mechanism 322 to release the abdominal pad so that it falls off and is placed on the material receiving door 327, and the material receiving door 327 is opened by pressing, and the abdominal pads located on the material receiving door 327 fall down stably and neatly and are stacked in the collection box.

[0065] like Figure 6 As shown, two sets of shifting mechanisms 124 are provided on one side of the pressing plate 118, and the two sets of shifting mechanisms 124 include a shifting plate 125 and a shifting power source 128 (cylinder). Slides 119 are symmetrically provided on both sides of the pressing plate 118. The shifting plate 125 includes a connecting portion 126 and a shifting portion 127 protruding downward. The connecting portion 126 is connected to the shifting power source 128. The connecting portion 126 and the shifting portion 127 are symmetrically provided with an upper limit groove and a lower limit groove, and the upper limit groove and the lower limit groove are symmetrically provided. The openings of the limit slots are opposite, the pressing piece 118 at the upper end of the slide 119 is embedded in the upper limit slot, and the pressing piece 118 at the lower end of the slide 119 is embedded in the lower limit slot. The angle shifting power source 128 drives the connecting part 126 to move in the horizontal direction, so that the angle shifting part 127 shifts a corner of the folded output fabric into the middle of the output fabric. The purpose of this process is to prevent the corners from overflowing outward during the process of folding and sewing the fabric, resulting in inadequate sewing of the corners or uneven side sewing, which ultimately leads to a reduction in the production yield.

[0066] like Figure 12As shown, a pressing and aligning assembly is provided on one side of the welding platform 251, and the pressing and aligning assembly includes a U-shaped block 255, a pressing power source 258, a pressing block 253 and an alignment pressing block 254. A notch is provided on the upper surface of the welding platform 251, and the second cutting knife passes through the U-shaped notch 256 of the U-shaped block 255 and is located in the notch. The upper surface of the welding platform 251 is divided into a first platform and a second platform by the notch, and the ultrasonic welding mechanism 250 is located above the first platform. A first through-groove 257 and a second through-groove are respectively provided on the first platform and the second platform. The first through-groove 257, the notch and the second through-groove are all connected and constitute a conveying channel for the output cotton strip and the output adhesive label to pass through at the same time. One end of the pressing block 253 is located on the U-shaped block 255, and the other end is located on the first through-groove 257. One end of the alignment pressing block 254 is located on the U-shaped block 255, and the other end is located on the second through-groove. The pressing power source 258 drives the U-shaped block 255 to move in the vertical direction so that the pressing block 253 presses The output adhesive label in the first through slot 257 is released, and the alignment pressing block 254 presses or releases the output cotton tape and the output adhesive label in the second through slot. The process is as follows: when the guide push rod 207 pushes the cotton tape toward one side of the welding table 251, the pressing block 253 is located above the first through slot 257, and the alignment pressing block 254 is located above the second through slot. The folded cotton tape passes through the first through slot 257, the notch, the second cutting shear and the second through slot in sequence. Before pushing, the initial end of the adhesive label is pressed by the pressing block 253 in the first through slot 257. The purpose is to prevent the adhesive label from detaching after cutting. When the guide push rod 207 pushes, the adhesive label is transported a distance to the bottom of the ultrasonic welding head. The folded cotton tape is pushed under the ultrasonic welding head. The adhesive label is now at the bottom of the lower layer of the folded cotton tape. The ultrasonic welding head welds the adhesive label on the cotton label. After welding, it continues to push to reach a certain amount. At the same time, the adhesive label is also transported to a certain amount. The second cutting shear cuts the adhesive label and the folded cotton tape.

[0067] like Figure 13As shown, the label placement mechanism 202 also includes a label traction assembly 233. A horizontal traction slide 234 is provided on the base on one side of the welding table 251. The traction slide 234 is laid along the movement direction of the guide push rod 207. The label traction assembly 233 includes a traction slide 235, a traction clamp, a third telescopic cylinder 237 and a traction power source 236. The traction slide 235 is slidably set on the traction slide 234. The traction clamp and the third telescopic cylinder 237 are both located on the traction slide 235. The traction clamp includes an upper clamp 238 and a lower clamp 239. There is a clamping distance between the upper clamp 238 and the lower clamp 239. The third telescopic cylinder 237 drives the traction clamp to move in the horizontal direction. , so that the bottom edge of the folded output cotton tape falls into the clamping spacing, and the traction power source 236 drives the base to move on the horizontal plane, so that the traction chuck pushes the folded part of the output cotton tape to one side. The process is: when the guide push rod 207 is pushed a certain distance, the folded part of the cotton label has passed the upper chuck 238 and the lower chuck 239, and the cylinder drives the traction chuck to make the lower chuck 239 extend into the middle of the fold, and the upper chuck 238 is located above the folded cotton tape. At this time, the guide push rod 207 moves out of the cotton tape and moves to the initial position to prepare for the next movement. The cylinder drives the traction chuck to move to one side, and the cotton tape can continue to be pulled and pushed to a certain length depending on the clamping spacing. The purpose is to make the cotton tape reach a specified length.

[0068] like Figure 8 As shown, the cutting mechanism 103 includes a knife frame 104, an upper cutter 106, a lower cutter 107 and a cutting power source 108 (cylinder). The lower cutter 107 is located at the bottom of one side of the working platform. The cutting power source 108 drives the upper cutter 106 to move in the vertical direction, so that the upper cutter 106 presses the conveyed fabric downward onto the lower cutter 107 to cut it. The movement direction of the upper cutter 106 is perpendicular to the conveying direction of the output fabric and crosses it (when the upper cutter 106 moves downward to act on the lower cutter 107, the output fabric is cut, and the upper cutter 106 cuts on the width of the output fabric, and the direction of the output fabric when conveying is the length direction). A pressing mechanism is also provided on the knife frame 104, as shown in FIG. Figure 7As shown, the clamping mechanism includes a pressing frame 129, a pressing plate 130, a feed plate 131, a first pressing power source 132 (cylinder) and a second pressing power source 133 (cylinder). The pressing frame 129 is slidably connected between the two sides of the knife frame 104, the feed plate 131 is located on the knife frame 104, and the feed plate 131 is on the same plane as the working platform, and the pressing plate 130 is located on the knife frame 104 above the feed plate 131. The first pressing power source 132 drives the pressing frame 129 to move in the horizontal direction so that the feed plate 131 pushes the conveyed fabric to the side of the folding mechanism 112, and the second pressing power source 133 drives the pressing block to move in the vertical direction so that the pressing block presses on the conveyed fabric on the feed plate 131. When the upper cutter 106 needs to move downward to act on the lower cutter 107, the purpose is to cut the output fabric, so the pressing plate 130 is needed to press the output fabric on one side of the cutter to prevent wrinkles from occurring during the cutting process.

[0069] like Figure 8 As shown, a lifting plate 134 is provided on one side of the lower cutter 107, and a lifting power source 135 (cylinder) is provided on both sides of the bottom of the lifting plate 134. The lifting power source 135 drives the lifting plate 134 to move in the vertical direction so that the lifting plate 134 lifts the side of the output fabric to be cut. Since the upper cutter 106 moves downward and acts on the lower cutter 107, the edge of the output fabric is cut, and the cut edge of the output fabric is pressed downward by the upper cutter 106 to the side of the lower cutter 107, that is, below the working platform. Therefore, a parallel lifting plate 134 is provided on one side of the lower cutter 107. When cutting is required, the lifting plate 134 moves downward. When the cutting is completed, the lifting plate 134 is reset upward and the side of the abdominal pad to be cut is lifted upward to be parallel to the working platform for subsequent conveying and folding.

[0070] Working principle: First, the fixed-length folding is performed, and the abdominal pad fabric roll 102 outputs the fabric and enters the working platform. When the head edge of the output fabric is conveyed to the top of the folding edge clamp 113, the pressing plate 118 presses the head edge downward into the first slot 114. At this time, the head edge will form a folding edge, and then the folding edge clamp 113 will clamp the head edge of the output fabric and lift it, and then the folding plate 110 moves in the conveying direction of the output fabric so that the folding plate 110 pushes the lifted output fabric to one side of the conveying direction, so that the output fabric is quantitatively folded in half, and when the folding plate 110 is pushed a certain distance, it stops, and the pick-and-place hand in the label tape placement device 2 will move the label tape into the folded position, and then the folding plate 110 is reset, the pressing plate 130 presses the output fabric downward, and the lifting plate 134 moves The upper cutter 106 acts downward on the lower cutter 107 to cut the output fabric, the upper cutter 106 is reset, the lifting plate 134 moves upward to lift the cut edge upward, and the tail edge of the abdominal pad fabric on the cut front side is located above the lower folding clamping plate 116, and the pressing plate 118 presses the head edge into the second slot 117 downward. At this time, the tail edge will form a folded edge. When the head edge and the tail edge are folded, the upper folding clamping plate 113 will rotate a certain angle to make the head edge parallel to the working platform, and then the head edge and the tail edge will be released, aligned and stacked, and then transferred to the discharge port. Then the placement hand 227 in the label placement device 2 will move toward the discharge port of the fixed-length folding device 1, clamp the abdominal pad and reset it, and then it will be taken away by the clamping mechanism 304 in the sewing device 3;

[0071] At the same time, in the label tape making process of the label tape placement device 2, the output cotton tape enters the multiple limit buckles of the guide plate 243 from the top, and then enters the conveying trough 244, and is output from the bottom end of the conveying trough 244 to between the first guide column 246 and the second guide column 247, wherein it passes through the first cutting knife 211, and the pulling power source 205 drives the positioning clamping hand 204 to move upward to clamp the initial end of the output cotton tape and then pull it downward. At this time, the output cotton tape is still being conveyed, and then it is folded in half under the action of the subsequent cotton tape guide assembly 206. When a certain requirement is met, the first cutting knife 211 cuts the output cotton tape, and the output cotton tape stops being conveyed at this time. After cutting, the output cotton tape head above is the new initial end again, and the limit buckle, conveying trough 244, baffle 245, The arrangement of the first guide post 246 and the second guide post 247 has an additional guiding limit effect compared to the existing direct transmission mechanism, and the first guide post 246 can move in the horizontal direction. Its purpose is to compress or loosen the output cotton strip, and to assist in the subsequent quantitative folding. When the guide push rod 207 pushes the cotton strip to the side of the welding table 251, the pressing block 253 is located above the first through slot 257, and the alignment pressing block 254 is located above the second through slot. The folded cotton strip passes through the first through slot 257, the notch, the second cutting knife and the second through slot in sequence. Before pushing, the initial end of the adhesive label is pressed into the first through slot 257 by the pressing block 253. The purpose is to prevent the adhesive label from detaching after cutting. When the guide push rod 207 pushes , the glue label is transported a distance to the bottom of the ultrasonic welding head, and the cotton tape is folded in half and pushed under the ultrasonic welding head. The glue label is now located at the bottom of the lower layer of the folded cotton tape, and the ultrasonic welding head welds the glue label on the cotton label. After welding, it continues to push to reach a certain amount. At the same time, the glue label is also transported to a certain amount, and the second cutting shears cuts the glue label and the folded cotton tape. When the guide push rod 207 pushes a certain distance, the folded part of the cotton label has passed the upper clamp 238 and the lower clamp 239, and the cylinder drives the traction clamp to make the lower clamp 239 extend into the middle of the fold, and the upper clamp 238 is located above the folded cotton tape. At this time, the guide push rod 207 moves out of the cotton tape and moves to the initial position to prepare for the next movement. The cylinder drives the traction clamp to move to one side The pick-up and delivery hand 223 is moved to one side so that the pick-up and delivery hand moves to one side of the working platform, and the cylinder drives the pick-up and delivery hand to move on the vertical slide rail 217. The movement enables the pick-up and delivery hand to transfer the clamped label to the fixed-length folding device 1 for loading the label. Compared with the pick-up and delivery hand in the prior art, the pick-up and delivery hand in the present invention can accurately clamp the two aligned free ends of the folded and welded label.After being clamped by the first protrusion 221 and the second protrusion 222, the pad can be stably transferred to the folded abdominal pad to prevent the two aligned free ends from being separated or shifted in position during the transfer process. The placement hand 227 will move toward the discharge port of the fixed-length folding device 1, clamp the abdominal pad, and then reset it;

[0072] Sewing process: First, the crossbeam 305 is driven by the power source to align the clamping arm 306 on the side away from the transfer mechanism 315 with the folded edge of the abdominal pad on the placement hand 227. This folded edge is the edge where the label tape is placed. Then, the clamping arm 306 on the side close to the moving mechanism is adjusted to align with the other folded edge of the abdominal pad on the folding placement hand 227. This edge is the head end and the tail end of the abdominal pad that are folded together and then clamped by the fixed-length folding device 1. The clamping arm 306 on this side is driven by the power source to move on the crossbeam 305, and the distance between the two sets of clamping arms 306 is adjusted. Then, the crossbeam 305 is driven by the power source to move back and forth. , so that the two sets of clamping arms 306 move to the abdominal pad of the folding processing device, the upper surface of the sewing lower clamping plate 310 is located on the bottom surface of the abdominal pad, and the bottom surface of the sewing upper clamping plate 307 is located on the upper surface of the abdominal pad, and the cylinder drives the sewing upper clamping plate 307 to move downward to press the folded edge of the abdominal pad onto the sewing lower clamping plate 310, and then the crossbeam 305 moves back to its original position, and the two sets of clamping arms 306 clamp the abdominal pad to the sewing platform 303, and the sewing machine 302 first sews the center line of the abdominal pad. After the center line is sewn, the sewing machine 302 moves to one side or the clamping arm 306 moves to one side of the sewing platform 303 to make The sewing needle is aligned with the folded edge to sew. When the two folded edges are sewn, the transfer mechanism 315 moves to the side of the clamping mechanism 304 under the drive of the cylinder. At this time, the upper pressing plate 130 is higher than the clamping arm 306, and the two vertical plates 317 are lower than the clamping arm 306. Therefore, the upper pressing plate 130 and the two vertical plates 317 are moved between the sewing platform 303 and the clamping arm 306, and the upper pressing plate 130 moves downward. The limit plate 328 first presses against the upper surface of the outer vertical plate 317, and the cylinder continues to drive the upper pressing plate 130 downward. The horizontal pressing part 320 of the upper pressing plate 130 acts on the limit plate 328, and the vertical The straight insertion part 321 presses the abdominal pad into the pressurized space 326. At this time, the cylinder drives one vertical plate 317 to move toward the other vertical plate 317 to clamp the pressed abdominal pad. Then the upper pressure plate 130 moves up and resets. The cylinder drives the slide plate 316 to move above the material receiving door 327. The two vertical plates 317 pull the abdominal pad to above the material receiving door 327. The two vertical plates 317 are released, and the abdominal pad falls horizontally on the material receiving door 327. At this time, the pressing rod 323 presses downward to open the material receiving door 327. As the material receiving door 327 opens, the abdominal pad slides to the middle to the collection box in the sewing machine frame 301, achieving neat stacking.
