[0002] After filling the medicine bag, the filling port needs to be sewn, but using an ordinary sewing machine to sew the filling port of the medicine bag will have the following problems:

[0003] 1. The remaining thread on the medicine bag after sewing is too long. Although ordinary sewing equipment can control the length of the thread at the end of the suture, it cannot control the length of the thread at the beginning. Therefore, it cannot meet the production requirements of the medicine bag. Secondary processing is often required to deal with the thread of the medicine bag, resulting in increased costs.

[0049] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0050] Reference Figures 1 to 6 The medicine bag suturing device of the embodiment of the present invention includes a sewing machine body 1000, a table 2000, a limiting device 3000 and a thread cutting device 4000. A machine needle 1100 is installed at the end of the sewing machine body 1000. The machine needle 1100 is a structure that almost every sewing machine body 1000 has, and is also the main structure for suturing medicine bags, which is not limited here; the sewing machine body 1000 can purchase existing sewing equipment, and the appropriate size and model can be purchased according to demand, which is not limited here.

[0051] Reference Figure 1 , Figure 2 As shown, the table 2000 is installed below the needle 1100; the table 2000 is provided with a positioning pin 2100 corresponding to the position of the needle 1100, and the positioning pin 2100 is movably installed on the table 2000; specifically, the filling port of the medicine bag is in the middle of the thickness direction of the medicine bag, so when the medicine bag is sutured, the medicine bag cannot be directly placed on the horizontal platform 2000, but a positioning pin 2100 protruding from the table 2000 is required to support the edge of the medicine bag to be sutured, so as to ensure the stability of the suture of the medicine bag. The positioning pin 2100 is preferably vertically movable to accommodate medicine bags of different sizes and models.

[0052] In the embodiments of the present invention, referring to Figure 1 As shown, the thread cutting device 4000 is installed on the table 2000 and is arranged on the periphery of the needle 1100; the thread cutting device 4000 includes a thread hooking assembly 4100 and a scissors assembly 4200, the table 2000 is provided with a first adjustment structure 2200 and a second adjustment structure 2300, the thread hooking assembly 4100 is connected to the first adjustment structure 2200 through a fastener, and the scissors assembly 4200 is connected to the second adjustment structure 2300 through a fastener, and the position of the thread hooking assembly 4100 can be adjusted by adjusting the connection position between the thread hooking assembly 4100 and the first adjustment structure 2200. Similarly, the position of the scissors assembly 4200 can be adjusted by adjusting the connection position between the scissors assembly 4200 and the second adjustment structure 2300, so that the action positions of the thread hooking assembly 4100 and the scissors assembly 4200 are more accurate, and the thread cutting device 4000 can also be made suitable for different types of medicine bags by adjusting the position. The first adjustment structure 2200 and the second adjustment structure 2300 can be manual adjustment structures or electric adjustment structures.

[0053] It should be understood that the hook thread assembly 4100 is used to hook the suture thread before suturing the medicine bag, and the scissor assembly 4200 is used to cut the suture thread between the hook thread assembly 4100 and the medicine bag; specifically, after the medicine bag is sewed using the conventional sewing machine body 1000, the sewing machine body 1000 will automatically cut the suture thread used to sew the medicine bag, and the length of the thread automatically cut by the sewing machine body 1000 is not long, which can meet the production requirements of the medicine bag, that is, after the medicine bag is sewed, the length of the thread remaining at the tail end of the suturing position of the medicine bag is usually able to meet the production requirements of the medicine bag; but currently the sewing machine body 1000 cannot control the length of the thread remaining at the head end of the suturing position after the medicine bag is sewed, so there will be a problem that some medicine bags do not meet the production requirements after suturing, and the medicine bags that do not meet the production requirements can either be discarded or need to be processed twice, which will greatly increase the production cost; in addition, since the medicine bag is filled with flammable materials, each additional processing level will increase the processing risk. In order to solve the above-mentioned technical problems and ensure that the length of the remaining thread at the beginning of the suture position after each suture is completed meets the production requirements of the medicine pack, the present application proposes a technical solution of arranging the thread hook assembly 4100 and the scissors assembly 4200 on the periphery of the needle 1100 of the sewing machine body 1000 to ensure that the remaining thread at the beginning of the suture position after each suture is completed meets the production requirements of the medicine pack.

[0054] Furthermore, the limiting device 3000 is arranged between the table 2000 and the sewing machine body 1000, and the limiting device 3000 is used to convey the medicine package to the bottom of the machine needle 1100; the limiting device 3000 includes a limiting component 3100, a clamping component 3200 and a moving component 3300, the limiting component 3100 is used to pre-position the medicine package, the clamping component 3200 is used to clamp the medicine package placed on the limiting component 3100, and the moving component 3300 is used to drive the clamping component 3200 and the limiting component 3100 to move. The medicine package suturing device of the embodiment of the present invention can reduce the shaking of the medicine package, ensure the stability of the medicine package, and thus reduce the suturing risk by setting the limiting device 3000 to fix the medicine package and drive the medicine package to move; by setting the thread cutting device 4000 to control the thread end of the medicine package at the suturing part, the production demand of the medicine package is met, the secondary processing cost is reduced, and the yield rate and processing efficiency are improved.

[0055] In an embodiment of the present invention, the thread hook assembly 4100 includes a first telescopic structure 4110, a hook piece 4120 and a suction structure 4130. The fixed end of the first telescopic structure 4110 is connected to the first adjustment structure 2200 via a fastener. The hook piece 4120 is installed at the movable end of the first telescopic structure 4110. The suction structure 4130 is installed below the hook piece 4120. The suction structure 4130 is connected to a vacuum device, and the suction structure 4130 is used to suck away the cut thread ends. The scissors assembly 4200 includes a second telescopic structure 4210 and a wire cutter 4220. The fixed end of the second telescopic structure 4210 is connected to the second adjustment structure 2300 via a fastener, and the wire cutter 4220 is installed at the movable end of the second telescopic structure 4210. For details, refer to Figure 2 As shown, the first telescopic structure 4110 is used to drive the hook piece 4120 to move toward the direction of the sewing machine body 1000 needle 1100, and the second telescopic structure 4210 is used to drive the thread cutter 4220 to move toward the direction of the sewing machine body 1000 needle 1100; the first telescopic structure 4110 and the second telescopic structure 4210 can be a telescopic cylinder 3332, a telescopic oil cylinder or an electric telescopic device. The vacuum device can be purchased according to actual needs. The vacuum device of suitable power and size is not limited here. The thread cutting device 4000 of the embodiment of the present invention hooks the thread through the hook piece 4120 of the hook assembly 4100, and then uses the thread cutter 4220 of the scissors assembly 4200 to cut the thread between the hook piece 4120 and the medicine bag, which can ensure that after the medicine bag is sutured, the length of the thread remaining at the head end of the suture position of the medicine bag meets the production requirements of the medicine bag, so that the medicine bag does not need to be processed twice, which greatly improves the production efficiency and reduces the production cost and risk.

[0056] In the embodiments of the present invention, referring to Figure 3 As shown, the end of the hook piece 4120 is arc-shaped; the hook piece 4120 is provided with a hook groove 4121, and the hook groove 4121 is arranged on one side of the width direction of the hook piece 4120. Specifically, the end of the hook piece 4120 is arranged in an arc shape so that when the hook piece 4120 moves toward the direction close to the wire, the wire can more easily enter the hook groove 4121 along the arc-shaped end surface. The hook groove 4121 is in a "7" shape, and the angle of the hook groove 4121 is preferably an acute angle, so that the wire is not easy to escape from the hook groove 4121 after the hook piece 4120 hooks the wire.

[0057] In the embodiment of the present invention, the suction structure 4130 is provided with a suction hole 4131, the first end of the suction hole 4131 is connected to the vacuum device, the second end of the suction hole 4131 is arranged on the side of the suction structure 4130 facing the hook 4120; the second end of the suction hole 4131 is arranged on the end of the suction structure 4130 away from the first telescopic structure 4110. Figure 4As shown, the suction hole 4131 is arranged inside the suction structure 4130, and the aperture of the second end of the suction hole 4131 is preferably smaller than the width of the hook piece 4120, and the aperture of the first end of the suction hole 4131 can be specifically set according to actual conditions. The second end of the suction hole 4131 is arranged on the side facing the hook piece 4120, which can ensure that after the line is hooked by the hook piece 4120, the line can more easily enter the suction hole 4131, and then after the line is cut, the line end can be sucked away by the suction hole 4131. The second end of the suction hole 4131 in the length direction is arranged to be closer to the hook groove 4121 of the hook piece 4120, so that the relative movement distance between the hook piece 4120 and the suction structure 4130 can be appropriately reduced, reducing the wear of both, and extending the service life of the device.

[0058] Furthermore, the suction structure 4130 is wedge-shaped, and the end of the suction structure 4130 is arc-shaped, thereby reducing interference with the wire and further increasing the probability of the wire being sucked into the suction hole 4131.

[0059] In the embodiment of the present invention, the hooking assembly 4100 further includes a bracket 4140 and a pressing sheet 4150. The fixed end of the first telescopic structure 4110 and the pressing sheet 4150 are both mounted on the bracket 4140. The hooking sheet 4120 is disposed between the pressing sheet 4150 and the suction structure 4130. Figure 3 , Figure 4 As shown, the pressing sheet 4150 is an elastic sheet. The purpose of setting the flattening is to tension the wire between the hook sheet 4120 and the medicine package, so as to facilitate the scissors assembly 4200 to cut the wire between the hook sheet 4120 and the medicine package, and also ensure that the wire cutter 4220 can cut the wire between the hook sheet 4120 and the medicine package each time. When the hook sheet 4120 hooks the wire into the hook groove 4121, the movable end of the first telescopic structure 4110 retracts to drive the hook sheet 4120 to move away from the medicine package, and the wire hooked by the hook groove 4121 of the hook sheet 4120 will be compressed between the pressing sheet 4150 and the hook sheet 4120. Since the hook sheet 4120 and the pressing sheet 4150 need to slide relative to each other, and the pressing sheet 4150 needs to apply pressure to the hook sheet 4120 to tension the wire between the hook sheet 4120 and the medicine package, the pressing sheet 4150 needs to be elastic; preferably, the pressing sheet 4150 is made of metal.

[0060] It can be imagined that the suction force applied by the suction structure 4130 to the thread end needs to be greater than the force of the pressing plate 4150 clamping the thread end onto the hook piece 4120. When the thread between the hook piece 4120 and the medicine package is cut, in order to ensure that the thread clamped between the hook piece 4120 and the pressing plate 4150 can be sucked away by the suction hole 4131, it is necessary to ensure that the suction force applied by the suction hole 4131 to the thread end is greater than the force of the pressing plate 4150 pressing the thread end onto the hook piece 4120. The specific force is not limited in this embodiment and can be set according to actual conditions.

[0061] It should be understood that during each suturing process of the medicine bag, the suction hole 4131 will inhale air twice. The first time is before the hook piece 4120 moves, the vacuum device moves to generate suction in the suction hole 4131, and the suction generated by the suction hole 4131 will attract the thread on the needle 1100 of the sewing machine body 1000 to the hook piece 4120, so that the hook piece 4120 can easily and accurately hook the thread into the hook groove 4121; the second time is before the scissor assembly 4200 moves, the vacuum device moves to generate suction in the suction hole 4131, so that after the thread cutter 4220 cuts the thread between the hook piece 4120 and the medicine bag, the suction hole 4131 can suck the thread end into the suction hole 4131. In summary, the suction hole 4131 plays the role of guiding the thread and collecting thread end garbage during the entire operation.

[0062] In an embodiment of the present invention, the limiting assembly 3100 includes a first limiting plate 3110, a second limiting plate 3120 and a laminate 3130. The first limiting plate 3110 and the second limiting plate 3120 are arranged at intervals in the vertical direction. The laminate 3130 is installed between the first limiting plate 3110 and the second limiting plate 3120. The laminate 3130 is provided with a limiting groove 3131 for the drug package to be inserted into; the first limiting plate 3110, the second limiting plate 3120, and the laminate 3130 are detachably connected by fasteners; specifically, refer to Figure 5 As shown, the second limit plate 3120 is arranged below the first limit plate 3110, and the fastener is preferably a bolt. The stack 3130 is provided with a plurality of through holes penetrating the stack 3130. The first limit plate 3110 and the second limit plate 3120 are also provided with through holes for the bolts to pass through at positions corresponding to the through holes on the stack 3130. The bolts pass through the first limit plate 3110, the stack 3130 and the second limit plate 3120 in sequence to lock the three.

[0063] Further, see Figure 5 As shown, a plurality of stacking sheets 3130 are provided, and the plurality of stacking sheets 3130 are stacked and arranged between the first limiting plate 3110 and the second limiting plate 3120; the thickness of the stacking sheets 3130 is relatively small, and by increasing or decreasing the thickness of the stacking sheets 3130, medicine packages of different sizes and thicknesses can be used, thereby improving the applicability of the limiting device 3000 of this embodiment; the shape of the limiting groove 3131 of the medicine package is set according to the shape of the medicine package, and is not specifically limited in this embodiment.

[0064] In the embodiment of the present invention, the clamping assembly 3200 is installed on the first limiting plate 3110; the clamping assembly 3200 includes a first clamping structure 3210 and a second clamping structure 3220, which are arranged on opposite sides of the limiting groove 3131, and the first clamping structure 3210 and the second clamping structure 3220 can slide toward each other to clamp the medicine package in the limiting groove 3131. For details, refer to Figure 5 As shown, when the medicine packages are being loaded and unloaded, the first clamping structure 3210 and the second clamping structure 3220 move in opposite directions to facilitate the loading and unloading of the medicine packages, which can be done manually or mechanically. After the medicine packages are loaded into the limiting groove 3131 of the stack 3130, the first clamping structure 3210 and the second clamping structure 3220 move toward each other to clamp the medicine packages in the limiting groove 3131.

[0065] In the embodiment of the present invention, the first clamping structure 3210 includes a first horizontal telescopic structure 3211, a first mounting plate 3212 and a first clamping member 3213, the first clamping member 3213 is adjustably mounted on the first mounting plate 3212, and the first mounting plate 3212 is adjustably mounted on the first horizontal telescopic structure 3211; the first clamping member 3213 is provided with a first clamping groove 3214 for clamping a medicine package, and the second clamping member 3223 is provided with a second clamping groove 3224 for clamping a medicine package. For details, refer to Figure 2 As shown, the shapes of the first clamping groove 3214 and the second clamping groove 3224 are consistent with the shape of the medicine package; the first clamping member 3213 can slide horizontally and be fixed relative to the first mounting plate 3212, and the first clamping member 3213 is connected to the first mounting plate 3212 by fasteners such as bolts; similarly, the first mounting plate 3212 can be vertically lifted and fixed relative to the first horizontal telescopic structure 3211, and the first mounting plate 3212 is connected to the movable end of the first horizontal telescopic structure 3211 by fasteners such as bolts; the first horizontal telescopic structure 3211 can be a telescopic cylinder 3332, a telescopic oil cylinder, a telescopic motor and other equipment; the first clamping member 3213 can be adjusted horizontally relative to the first mounting plate 3212, and the first mounting plate 3212 can be adjusted vertically relative to the first horizontal telescopic structure 3211, so that more types of medicine packages can be applied. Since the size variation between different medicine packages is relatively small, the clamping position of the medicine package can be accurately controlled by adjusting the first clamping member 3213 and the first mounting plate 3212 to ensure the stability of the medicine package after being clamped.

[0066] Similarly, refer to Figure 5As shown, the first clamping structure 3210 is basically the same as the first clamping structure 3210, and the second clamping structure 3220 includes a second horizontal telescopic structure 3221, a second mounting plate 3222 and a second clamping member 3223, the second clamping member 3223 is adjustably mounted on the second mounting plate 3222, and the second mounting plate 3222 is adjustably mounted on the movable end of the second horizontal telescopic structure 3221.

[0067] In the embodiment of the present invention, the first limit plate 3110 is installed on the moving assembly 3300, and the moving assembly 3300 is used to drive the first limit plate 3110 to move in the horizontal and vertical directions. It can be imagined that the adaptation of different types of medicine packages can also be achieved by changing the parameters of the moving assembly 3300, but there are differences in the adjustment purposes of the two. Since the size changes between different medicine packages are relatively small, the parameter setting of the moving assembly 3300 to adapt to different types of medicine packages is relatively complicated and difficult to achieve precise control. Therefore, the moving assembly 3300 is more to ensure that the filling port of the medicine package is accurately placed under the needle 1100 of the sewing machine body 1000, and the adjustment of the first clamping member 3213 and the first mounting plate 3212 is used to more accurately control the clamping of the medicine package.

The second drive structure 3320 and the third drive structure 3330 drive the first limit plate 3110 to slide horizontally in the same direction. The first drive structure 3310 and the second drive structure 3320 are used to drive the first limit plate 3110 to move to a set position, and the third drive structure 3330 is used to drive the medicine bag on the first limit plate 3110 to move to below the needle 1100 of the sewing machine body 1000.

[0069] In the embodiments of the present invention, referring to Figure 6As shown, the first driving structure 3310 includes a first slide rail 3311, on which a first slide seat 3312 is slidably installed, and the first slide seat 3312 is connected to a first power structure 3313 that drives it to slide along the first slide rail 3311; the second driving structure 3320 includes a base 3321, and the base 3321 is installed on the first slide seat 3312; specifically, the first driving structure 3310 includes a driving wheel, a driven wheel and a conveying belt, the conveying belt is sleeved on the driving wheel and the driven wheel, and the first power structure 3313 is connected to the driving wheel; there are two first slide rails 3311, and the two first slide rails 3311 are respectively arranged on both sides of the width direction of the conveying belt, and the two ends of the base 3321 of the first sliding structure in the length direction are respectively connected to the two first slide seats 3312, and the middle part of the base 3321 is connected to the conveying belt through a connecting piece, and the conveying belt can drive the base 3321 to slide along the first slide rail 3311 when it moves in the horizontal direction.

[0070] Furthermore, the base 3321 is provided with a second slide rail 3322, on which a second slide seat 3323 is slidably mounted, and the second slide seat 3323 is connected to a second power structure 3324 that drives it to slide along the second slide rail 3322; the third driving structure 3330 is mounted on the second slide seat 3323, and the length extension direction of the first slide rail 3311 is perpendicular to the length extension direction of the second slide rail 3322. Specifically, the second power structure 3324 is mounted on one end of the second slide rail 3322 in the length direction, and the second slide seat 3323 is connected to the output end of the second power structure 3324, and the second power structure 3324 is used to drive the second slide seat 3323 to slide along the second slide rail 3322.

[0071] In an embodiment of the present invention, the third driving structure 3330 includes a telescopic cylinder 3332, the movable end of the telescopic cylinder 3332 is connected to the vertical plate 3331, and the first limit plate 3110 is installed on the vertical plate 3331 in a manner that it can be raised and lowered. The limit device 3000 also includes a table 2000, and the table 2000 is provided with a positioning pin 2100 protruding from its surface. The telescopic cylinder 3332 of the third driving structure 3330 is used to drive the vertical plate 3331 to move in the horizontal direction, thereby driving the first limit plate 3110 to move, so that the filling port of the medicine package falls on the positioning pin 2100. Figure 6 As shown, in order to adapt to the size of the sewing machine body 1000, the telescopic cylinder 3332 of the third driving structure 3330 is not arranged in a straight line, but is arranged obliquely; similarly, referring to Figure 1 As shown, the height of the moving assembly 3300 in the vertical direction is also limited by the height direction of the sewing machine body 1000.

[0072] In the embodiment of the present invention, the limiting device 3000 further includes a housing 3400, which is disposed on the outer periphery of the first driving structure 3310 and the second driving structure 3320; the platform 2000 is connected to the housing 3400. Figure 1 As shown, the housing 3400 is provided with a slide groove 3410, and the length extension direction of the slide groove 3410 is the same as the length extension direction of the first slide rail 3311; a shield plate 3420 is slidably installed in the slide groove 3410, and the shield plate 3420 is connected to the third driving structure 3330; there are two shield plates 3420, and the two shield plates 3420 are respectively arranged on both sides of the width direction of the third driving structure 3330. The first driving structure 3310 drives the third driving structure 3330 to slide, which will drive the two shield plates 3420 to slide synchronously. A channel for the third driving structure 3330 to slide is reserved between the two shield plates 3420 to avoid obstruction to the second driving structure 3320 driving the third driving structure 3330 to slide. The shield plate 3420 can better protect the first driving structure 3310 and the second driving structure 3320, reduce the debris and dust in the processing process from entering the first driving structure 3310 or the second driving structure 3320, and thus extend the service life of the moving component 3300.

[0074] S1. The moving assembly 3300 moves to the loading position, the loading device places the medicine package in the limiting assembly 3100, and then the clamping assembly 3200 clamps the medicine package located in the limiting assembly 3100;

[0075] S2, the moving assembly 3300 moves from the loading position to the processing position to transport the medicine package to the bottom of the machine needle 1100;

[0076] S3, the thread hooking assembly 4100 moves once toward the direction close to the machine needle 1100 to hook the suture thread on the machine needle 1100; the thread hooking assembly 4100 moves once toward the direction of the machine needle 1100 means that the first telescopic structure 4110 drives the hook piece 4120 to complete an extension and retraction action, so that the end of the suture thread on the machine needle 1100 is clamped between the pressing piece 4150 and the hook piece 4120;

[0077] S4, the machine needle 1100 sews up the medicine bag;

[0078] S5.
