[0039] Reference Figures 1 to 3The limiting device according to a first aspect of the present invention includes a limiting component 100, a clamping component 200, and a moving component 300. The limiting component 100 is used to limit the medicine pack in the vertical direction, the clamping component 200 is used to limit the medicine pack in the horizontal direction, and the moving component 300 is used to drive the medicine pack to move from the feeding position to below the needle of the sewing machine. The limiting component 100 pre-positions the medicine pack, ensuring convenient installation; the clamping component 200 clamps the medicine pack in the horizontal direction, ensuring stability and improving safety during sewing; and the moving component 300 drives the medicine pack to move, increasing automation in the sewing process, reducing labor costs, and improving processing efficiency.

[0040] In an embodiment of the present invention, the limiting component 100 includes a first limiting plate 110, a second limiting plate 120, and a stacked piece 130. The first limiting plate 110 and the second limiting plate 120 are spaced apart in a vertical direction, and the stacked piece 130 is installed between the first limiting plate 110 and the second limiting plate 120. The stacked piece 130 is provided with a limiting groove 131 for inserting a medicine pack. The first limiting plate 110, the second limiting plate 120, and the stacked piece 130 are detachably connected by fasteners. Specifically, refer to... Figure 2 As shown, the second limiting plate 120 is located below the first limiting plate 110. The fastener is preferably a bolt. The stacked plate 130 is provided with multiple through holes penetrating the stacked plate 130. The first limiting plate 110 and the second limiting plate 120 are also provided with through holes for bolts to pass through at the positions of the through holes on the stacked plate 130. The bolts pass through the first limiting plate 110, the stacked plate 130 and the second limiting plate 120 in sequence to lock the three together.

[0041] Furthermore, refer to Figure 2 As shown, multiple stacked pieces 130 are provided, and multiple stacked pieces 130 are stacked between the first limiting plate 110 and the second limiting plate 120. The thickness of the stacked pieces 130 is relatively small. By increasing or decreasing the thickness of the stacked pieces 130, medicine packs of different sizes and thicknesses can be used, thereby improving the applicability of the limiting device in this embodiment. The shape of the limiting groove 131 of the medicine pack is set according to the shape of the medicine pack, and is not specifically limited in this embodiment.

[0042] In an embodiment of the present invention, the clamping assembly 200 is mounted on the first limiting plate 110; the clamping assembly 200 includes a first clamping structure 210 and a second clamping structure 220, which are disposed on opposite sides of the limiting groove 131. The first clamping structure 210 and the second clamping structure 220 can slide towards each other to clamp the medicine pack located in the limiting groove 131. Specifically, refer to... Figure 2As shown, when the medicine package is being loaded and unloaded, the first clamping structure 210 and the second clamping structure 220 move in opposite directions to facilitate the loading and unloading of the medicine package. The loading and unloading of the medicine package can be done manually or mechanically. After the medicine package is placed into the limiting groove 131 of the stack 130, the first clamping structure 210 and the second clamping structure 220 move towards each other to clamp the medicine package located in the limiting groove 131.

[0043] In an embodiment of the present invention, the first clamping structure 210 includes a first horizontal telescopic structure 211, a first mounting piece 212, and a first clamping member 213. The first clamping member 213 is adjustablely mounted on the first mounting piece 212, and the first mounting piece 212 is adjustablely mounted on the first horizontal telescopic structure 211. The first clamping member 213 is provided with a first clamping groove 214 for clamping a medicine pack, and the second clamping member 223 is provided with a second clamping groove 224 for clamping a medicine pack. Specifically, refer to... Figure 2 As shown, the shapes of the first clamping groove 214 and the second clamping groove 224 conform to the shape of the medicine pack; the first clamping member 213 can slide horizontally and be fixed relative to the first mounting plate 212, and the first clamping member 213 is connected to the first mounting plate 212 by fasteners such as bolts; similarly, the first mounting plate 212 can be raised and lowered vertically relative to the first horizontal telescopic structure 211 and fixed, and the movable end of the first mounting plate 212 and the first horizontal telescopic structure 211 are connected by fasteners such as bolts; the first horizontal telescopic structure 211 can be a telescopic cylinder 332, a telescopic hydraulic cylinder, a telescopic motor, or other equipment; by adjusting the first clamping member 213 horizontally relative to the first mounting plate 212 and the first mounting plate 212 vertically relative to the first horizontal telescopic structure 211, it can be used for more types of medicine packs. Since the size difference between different medicine packs is relatively small, by adjusting the first clamping member 213 and the first mounting plate 212, the clamping position of the medicine pack can be precisely controlled, ensuring the stability of the medicine pack after clamping.

[0044] Similarly, refer to Figure 2 As shown, the first clamping structure 210 is basically the same as the second clamping structure 220. The second clamping structure 220 includes a second horizontal telescopic structure 221, a second mounting piece 222, and a second clamping member 223. The second clamping member 223 is adjustablely mounted on the second mounting piece 222, and the second mounting piece 222 is adjustablely mounted on the movable end of the second horizontal telescopic structure 221.

[0045] The limiting device in this embodiment of the invention also includes a moving component 300. A first limiting plate 110 is mounted on the moving component 300, and the moving component 300 is used to drive the first limiting plate 110 to move in the horizontal and vertical directions. It is conceivable that different types of medicine packs can also be adapted by changing the parameters of the moving component 300, but the adjustment purposes of the two are different. Since the size difference between different medicine packs is relatively small, adapting different types of medicine packs by using the moving component 300 is more complicated in terms of parameter setting and difficult to achieve precise control. Therefore, the moving component 300 is more for ensuring that the filling port of the medicine pack is accurately positioned under the needle of the sewing machine. The adjustment of the first clamping member 213 and the first mounting piece 212 is used to more precisely control the clamping of the medicine pack.

[0046] In an embodiment of the present invention, the moving component 300 includes a first driving structure 310, a second driving structure 320, and a third driving structure 330. The second driving structure 320 is mounted on the first driving structure 310, the third driving structure 330 is mounted on the second driving structure 320, and the first limiting plate 110 is mounted on the third driving structure 330. The first driving structure 310, the second driving structure 320, and the third driving structure 330 are used to drive the first limiting plate 110 to slide horizontally. The directions in which the first driving structure 310 and the second driving structure 320 drive the first limiting plate 110 to slide horizontally are perpendicular, and the directions in which the second driving structure 320 and the third driving structure 330 drive the first limiting plate 110 to slide horizontally are the same. The first driving structure 310 and the second driving structure 320 are used to drive the first limiting plate 110 to move to a set position, and the third driving structure 330 is used to drive the medicine pack on the first limiting plate 110 to move below the needle of the sewing machine.

[0047] In an embodiment of the present invention, reference is made to Figure 3 As shown, the first drive structure 310 includes a first slide rail 311 and a first slide block 312 slidably mounted on the first slide rail 311. The first slide block 312 is connected to a first power structure 313 that drives it to slide along the first slide rail 311. The second drive structure 320 includes a base 321, which is mounted on the first slide block 312. Specifically, the first drive structure 310 includes a drive wheel, a driven wheel, and a conveyor belt. The conveyor belt is sleeved on the drive wheel and the driven wheel. The first power structure 313 is connected to the drive wheel. There are two first slide rails 311, which are respectively located on both sides of the width direction of the conveyor belt. The two ends of the base 321 of the first sliding structure are respectively connected to the two first slide blocks 312 in the length direction. The middle part of the base 321 is connected to the conveyor belt through a connector. The horizontal movement of the conveyor belt can drive the base 321 to slide along the first slide rail 311.

[0048] Furthermore, the base 321 is provided with a second slide rail 322, on which a second slide block 323 is slidably mounted. The second slide block 323 is connected to a second power structure 324 that drives it to slide along the second slide rail 322. A third drive structure 330 is mounted on the second slide block 323, and the length extension direction of the first slide rail 311 is perpendicular to the length extension direction of the second slide rail 322. Specifically, the second power structure 324 is mounted at one end of the length direction of the second slide rail 322, and the second slide block 323 is connected to the output end of the second power structure 324. The second power structure 324 is used to drive the second slide block 323 to slide along the second slide rail 322.

[0049] In an embodiment of the present invention, the third driving structure 330 includes a telescopic cylinder 332, the movable end of which is connected to a vertical plate 331. A first limiting plate 110 is adjustablely mounted on the vertical plate 331. The limiting device also includes a platform 400, which has a positioning pin 410 protruding from its surface. The telescopic cylinder 332 of the third driving structure 330 drives the vertical plate 331 to move horizontally, thereby moving the first limiting plate 110 so that the filling port of the medicine bag falls onto the positioning pin 410. (Refer to...) Figure 3 As shown, to accommodate the size of the sewing machine, the telescopic cylinder 332 of the third drive structure 330 is not linearly positioned, but rather inclined; similarly, refer to... Figure 4 As shown, the vertical height of the moving component 300 is also limited by the height of the sewing machine. (Refer to...) Figure 1 As shown, the filling port of the medicine bag is located in the middle of the thickness direction of the medicine bag. Therefore, when sewing the medicine bag, it cannot be placed directly on the horizontal platform plate 400. Instead, a positioning pin 410 protruding from the platform plate 400 is needed to support the edge of the medicine bag to be sewn, so as to ensure the stability of the medicine bag sewing. The positioning pin 410 is preferably vertically adjustable to accommodate medicine bags of different sizes and models.

[0050] In an embodiment of the present invention, the limiting device further includes a housing 500, which covers the outer periphery of the first driving structure 310 and the second driving structure 320; the platform 400 is connected to the housing 500. Specifically, refer to... Figure 1As shown, the outer casing 500 is provided with a slide groove 510, the length extension direction of which is the same as the length extension direction of the first slide rail 311; a cover plate 520 is slidably installed in the slide groove 510, and the cover plate 520 is connected to the third drive structure 330; there are two cover plates 520, which are respectively arranged on both sides of the width direction of the third drive structure 330. When the first drive structure 310 drives the third drive structure 330 to slide, it will drive the two cover plates 520 to slide synchronously. A channel is left between the two cover plates 520 for the third drive structure 330 to slide, so as to avoid obstructing the sliding of the second drive structure 320 driving the third drive structure 330. The cover plate 520 can better protect the first drive structure 310 and the second drive structure 320, reduce the entry of debris and dust into the first drive structure 310 or the second drive structure 320 during the processing, thereby extending the service life of the moving component 300.

[0051] Reference Figure 4 As shown, the medicine pack sewing device according to the second aspect of the present invention includes a sewing machine and the aforementioned limiting device. The limiting device is installed below the sewing machine. Since the medicine pack sewing device includes the aforementioned limiting device, it has at least all the beneficial effects of the limiting device, which will not be elaborated here.
