Description

Technical Field

[0001] This invention relates to the field of pharmaceutical packaging manufacturing technology, and in particular to a dispensing device, dispensing method, and pharmaceutical packaging filling equipment. Background Technology

[0002] Currently, the industry commonly uses manual filling for medicine packets, where weighed powder is manually poured into the packets. The powder weighing process varies, sometimes using automated weighing systems and sometimes manual weighing. This filling method has the following problems:

[0003] 1. The manual labor is intense and the filling efficiency is low;

[0004] 2. The precise amount of medicine filled into the medicine bag is difficult to control, resulting in a low yield rate;

[0005] 3. The dosage of the explosive was not verified, which affected the quality of the explosive package. In the event of a fire or explosion, it would directly endanger the personal safety of the workers. Summary of the Invention

[0006] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a dispensing device and dispensing method, which can improve the weighing accuracy of medicine powder, thereby improving the yield of medicine packets.

[0007] The present invention also proposes a medicine bag filling device including the above-mentioned batching device.

[0008] A dispensing apparatus according to a first aspect of the present invention includes:

[0009] A turntable is connected to a drive device that drives it to rotate around its own axis; a medicine cartridge is mounted on the turntable, and the rotation of the turntable can drive the medicine cartridge to rotate synchronously; the medicine cartridge has a volume cavity for containing medicine powder, and a sealing structure is connected to the bottom of the medicine cartridge, the sealing structure having a first position for sealing the bottom of the volume cavity and a second position for opening the bottom of the volume cavity;

[0010] The support includes a fixing plate, on which a coarse feeding structure and a fine feeding structure are mounted, both of which are used to add powder to the cartridge.

[0011] A weighing structure is mounted on the bracket;

[0012] The first top-opening structure is used to drive the sealing structure to switch from the first position to the second position so as to pour the medicine powder in the cartridge into the waste bin;

[0013] The second top-opening structure is used to drive the sealing structure to switch from the first position to the second position so as to pour the medicine powder in the medicine cartridge into the medicine bag;

[0014] Along the rotation direction of the turntable, the coarse feeding structure, the weighing structure, the fine feeding structure, the first top-opening structure, and the second top-opening structure are arranged sequentially.

[0015] The dispensing apparatus according to embodiments of the present invention has at least the following beneficial effects:

[0016] By setting up a coarse feeding structure and a fine feeding structure, with the fine feeding structure placed after the coarse feeding structure, the powder is precisely added to the medicine cartridge after the powder has been added by the coarse feeding structure, which can improve the accuracy of the medicine weighing. The weighing structure, the first top opening structure and the second top opening structure can remove the powder in the medicine cartridge that does not meet the set weight, thereby improving the yield of medicine packs.

[0017] According to some embodiments of the present invention, the coarse feeding structure includes a storage funnel, a quantitative adjustment structure, and a discharge pipe. The quantitative adjustment structure is disposed between the storage funnel and the discharge pipe, and the quantitative adjustment structure adjusts the set discharge amount of the coarse feeding structure.

[0018] According to some embodiments of the present invention, the amount of powder added to the cartridge by the coarse feeding structure and the fine feeding structure at one time is a set discharge amount, and the set discharge amount of the coarse feeding structure is greater than the set discharge amount of the fine feeding structure.

[0019] According to some embodiments of the present invention, the fine feeding structure is provided in multiple ways, and the set output amount of the multiple fine feeding structures decreases sequentially along the rotation direction of the turntable.

[0020] According to some embodiments of the present invention, the turntable is equipped with a plurality of cartridges, which are spaced apart around the circumference; the turntable rotates unidirectionally around its own axis.

[0021] According to a second aspect of the present invention, the dispensing method is applicable to the above-described dispensing apparatus; the weight of the powder to be poured into the medicine packet is defined as a set weight, the weight of the powder in the set output amount of the coarse feeding structure is a first weight, and the weight of the powder in the set output amount of the fine feeding structure is a second weight; since there are multiple fine feeding structures, there are multiple second weights;

[0022] The preparation steps are as follows:

[0023] The coarse feeding structure adds a first weight of medicinal powder into the cartridge.

[0024] The weighing structure weighs the first weight of the powder, and executes a corresponding configuration strategy according to the weighing structure to control the operation of the fine feeding structure, the first top opening structure, and the second top opening structure.

[0025] The configuration strategy is as follows:

[0026] If the first weight is greater than the set weight, the first opening structure is activated to pour the powder in the cartridge into the waste bin.

[0027] If the first weight is equal to the set weight, the second opening structure is activated to pour the powder in the medicine cartridge into the medicine bag;

[0028] If the first weight is less than the set weight, then the sum of the first weight and at least one second weight is calculated so that the sum of the first weight and at least one second weight is equal to the set weight.

[0029] According to some embodiments of the present invention, if the sum of the first weight and at least one of the second weights is greater than the set weight, the fine feeding structure does not operate, and the first opening structure operates to pour the powder in the cartridge into the waste bin.

[0030] If the sum of all the second weights plus the first weight is still less than the set weight, the fine feeding structure does not operate, and the first opening structure operates to pour the powder in the cartridge into the waste bin.

[0031] According to the ingredient dispensing method of the present invention, the appropriate weight of medicine powder can be weighed more accurately, and excess medicine powder can be avoided from being poured into the medicine packet, thereby effectively improving the accuracy of medicine powder weighing and thus improving the yield of medicine packets.

[0032] According to a third aspect of the present invention, a medicine bag filling device includes a conveyor belt, a feeding device, a filling device, a weighing device, a waste rejection device, and the above-mentioned batching device;

[0033] The conveyor belt is used to transport medicine packets. The filling device, the weighing device, and the rejection device are arranged sequentially along the conveying direction of the conveyor belt. The filling device is used to fill the medicine packets on the conveyor belt with medicine powder. The weighing device is used to weigh the medicine packets after filling with medicine powder. The rejection device rejects medicine packets that do not meet the set weight from the conveyor belt according to the weighing result of the weighing device.

[0034] The feeding device is used to supply medicine packets onto the conveyor belt, and the dispensing device is used to deliver a set weight of medicine powder to the filling device.

[0035] According to some embodiments of the present invention, the filling device includes a bag support structure and a funnel structure, wherein the bag support structure is disposed at the lower part of the funnel structure; the bag support structure is connected to a first lifting structure that drives its operation, and the funnel structure is connected to a second lifting structure that drives its operation.

[0036] According to some embodiments of the present invention, the medicine bag filling equipment further includes a sealing device, which is disposed behind the filling device along the conveying direction of the conveyor belt; the sealing device is used to seal the medicine bag.

[0037] The medicine bag filling equipment according to embodiments of the present invention can realize automated filling of medicine bags, improve filling efficiency, and reduce labor costs; by conveying medicine powder to the filling device through the above-mentioned batching device, the accuracy of medicine powder weight can be effectively improved, thereby improving the yield of medicine bags; by setting a weighing device to re-weigh the medicine bags and setting a rejection device to reject medicine bags that do not meet the weight requirements, the yield of medicine bags is further improved.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0059] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0060] Reference Figure 2 , Figure 3 As shown, the dispensing device 1000 of the first aspect embodiment of the present invention includes a turntable 1100 and a support 1200. A medicine cylinder 1110 for loading medicinal powder is mounted on the turntable 1100, and a feeding structure for adding medicinal powder into the medicine cylinder 1110 is mounted on the support 1200. Specifically, the turntable 1100 is connected to a drive device 1101 that drives it to rotate around its own axis. The drive device 1101 is preferably a motor and is mounted on the bottom of the turntable 1100. The rotation of the turntable 1100 drives the medicine cylinder 1110 to rotate synchronously. Multiple medicine cylinders 1110 are provided, and the multiple medicine cylinders 1110 are evenly spaced around the circumference of the turntable 1100. The cartridge 1110 is used to load the powder. The cartridge 1110 has a volume cavity for containing the powder. The bottom of the cartridge 1110 is connected to a sealing structure 1111. The sealing structure 1111 has a first position that seals the bottom of the volume cavity and a second position that opens the bottom of the volume cavity. When the sealing structure 1111 is in the first position, the powder inside the cartridge 1110 will not fall out. When the sealing structure 1111 is in the second position, the powder inside the cartridge 1110 will fall out of the cartridge 1110.

[0061] In an embodiment of the present invention, the bracket 1200 includes a fixing plate 1201, as shown in the figure. Figure 2As shown, the fixing plate 1201 is positioned above the turntable 1100. The fixing plate 1201 is stationary; therefore, the turntable 1100 rotates relative to the fixing plate 1201 when rotating around its own axis. The fixing plate 1201 is equipped with a coarse feeding structure 1210 and a fine feeding structure 1220. Both the coarse feeding structure 1210 and the fine feeding structure 1220 are used to add powder to the cartridge 1110. The coarse feeding structure 1210 adds more powder to the cartridge 1110, while the fine feeding structure 1220 adds less powder. The bracket 1200 is also equipped with a weighing structure 1230, a first top-opening structure, and a second top-opening structure 1240. The weighing structure 1230 is used to weigh the powder in the cartridge 1110. The first top-opening structure and the second top-opening structure 1240 are both used to drive the sealing structure 1111 to switch from the first position to the second position. That is, the first top-opening structure and the second top-opening structure 1240 are both used to make the powder in the cartridge 1110 fall out of the cartridge 1110. However, the difference is that the positions of the first top-opening structure and the second top-opening structure 1240 are different. Therefore, after the first top-opening structure drives the sealing structure 1111 to switch to the second position, the powder in the cartridge 1110 will fall into the waste bin. After the second top-opening structure 1240 drives the sealing structure 1111 to switch to the second position, the powder in the cartridge 1110 will eventually be poured into the medicine bag. Since the fixed plate 1201 is located above the turntable 1100, both the fine feeding structure 1220 and the coarse feeding structure 1210 are located above the cartridge 1110. Therefore, both the coarse feeding structure 1210 and the fine feeding structure 1220 can flow into the cartridge 1110 by the weight of the powder itself, without the need for other power equipment, thereby effectively reducing production costs.

[0062] In an embodiment of the present invention, reference is made to Figure 2 , Figure 3 As shown, the sealing structure 1111 in this embodiment is a sealing plate, with the middle part of the sealing plate hinged to the cartridge 1110. The first section of the sealing plate is used to seal the bottom of the cartridge 1110. The first opening structure and the second opening structure 1240 are both telescopic cylinders. The movable end of the first opening structure or the second opening structure 1240 extends out and abuts against the second end of the sealing plate and pushes the sealing plate to rotate around the hinge point with the cartridge 1110, thereby realizing the powder inside the cartridge 1110 falling out.

[0063] It is conceivable that the sealing structure 1111 is not limited to using a sealing plate, and the first top opening structure and the second top opening structure 1240 are not limited to using telescopic cylinders. Appropriate sealing structures 1111, first top opening structures, and second top opening structures 1240 can be selected according to the actual situation.

[0064] In an embodiment of the present invention, the coarse feeding structure 1210 includes a storage funnel 1211, a metering adjustment structure 1212, and a discharge pipe 1213. The metering adjustment structure 1212 is disposed between the storage funnel 1211 and the discharge pipe 1213, and the metering adjustment structure 1212 adjusts the set discharge amount of the coarse feeding structure 1210. Specifically, refer to... Figure 2 , Figure 4 As shown, the storage funnel 1211 is used to store the medicine powder, and the quantitative adjustment structure 1212 is used to control the amount of medicine powder flowing out of the storage funnel 1211 through the discharge pipe 1213 at one time. Since the amount of medicine powder that needs to be filled in different specifications of medicine packs is different, the quantitative adjustment structure 1212 can make the dispensing device 1000 of this embodiment applicable to medicine packs of various specifications. The quantitative adjustment structure 1212 can adopt various technical solutions, which are not limited in this embodiment.

[0065] Reference Figure 2 As shown, the fine feeding structure 1220 and the coarse feeding structure 1210 in this embodiment are basically the same, except that the amount of powder discharged by the fine feeding structure 1220 in a single flow is less than the amount of powder discharged by the coarse feeding structure 1210 in a single flow. That is, the set discharge amount of the coarse feeding structure 1210 is greater than the set discharge amount of the fine feeding structure 1220. The set discharge amount refers to the amount of powder added to the cartridge 1110 by the coarse feeding structure 1210 or the fine feeding structure 1220 in a single flow. The fine feeding structure 1220 and the coarse feeding structure 1210, which have basically the same structure, can effectively reduce manufacturing and maintenance costs.

[0066] In embodiments of the present invention, multiple fine feeding structures 1220 are provided. Along the rotation direction of the turntable 1100, the set output amount of the multiple fine feeding structures 1220 decreases sequentially. The set output amount of the multiple fine feeding structures 1220 can be set according to actual conditions. It should be understood that the turntable 1100 of the dispensing device 1000 in this embodiment rotates in one direction only, and the turntable 1100 rotates intermittently. After each unidirectional rotation, the turntable 1100 pauses for a set duration. For example, if eight cartridges 1110 are spaced apart on the turntable 1100 in this embodiment, the turntable 1100 rotates 45 degrees each time. The set duration of the pause can be set according to actual conditions, such as 2 seconds, 3 seconds, etc. Since the turntable 1100 rotates in one direction and the duration of each stop is equal, during one revolution of the turntable 1100, the coarse feeding structure 1210 and the fine feeding structure 1220 can only add powder to a single cartridge 1110 once. Therefore, in order to better calculate which fine feeding structure 1220 needs to be added to the cartridge 1110 after the powder is added by the coarse feeding structure 1210, and also to better understand the operating logic of this embodiment, the multiple fine feeding structures 1220 are set to be along the rotation direction of the turntable 1100, and the set output of the multiple fine feeding structures 1220 decreases sequentially. However, according to actual needs, the multiple fine feeding structures 1220 can also be set to be along the rotation direction of the turntable 1100, and the set output of the multiple fine feeding structures 1220 can increase sequentially, or can be set arbitrarily.

[0067] The reason for setting up the fine feeding structure 1220 and the coarse feeding structure 1210 is that the feeding error of the coarse feeding structure 1210 is greater than the error range of the required powder weight of the medicine bag. Therefore, it is necessary to set up the fine feeding structure 1220 to replenish the powder. For example, if a single medicine bag needs to be filled with 100 grams of powder with an error range of ±3%, and the set output of the coarse feeding structure 1210 is set to 100 grams, the coarse feeding structure 1210 has an error of ±5%. Therefore, using only the coarse feeding structure 1210 to fill the medicine bag will result in a low yield. However, by adding multiple fine feeding structures 1220 to replenish the powder, this problem can be effectively solved. For example, taking the case where a single medicine packet needs to be filled with 100 grams of powder, with an error range of plus or minus 3%, first set the output of the coarse feeding structure 1210 to 95 grams, and then, along the rotation direction of the turntable 1100, set the output of the fine feeding structure 1220 to 5 grams, 2 grams, etc. Although the fine feeding structure 1220 will also have errors, since the fine feeding structure 1220 itself adds a small amount of powder, the resulting error in grams is also small, thus effectively improving the yield of medicine packets.

[0068] In an embodiment of the present invention, along the rotation direction of the turntable 1100, the coarse feeding structure 1210, the weighing structure 1230, the fine feeding structure 1220, the first top-opening structure, and the second top-opening structure 1240 are arranged sequentially. Therefore, the feeding process of the batching device 1000 in this embodiment is as follows:

[0069] First, define the weight of the powder to be poured into the medicine bag as the set weight. The weight of the powder in the set output of the coarse feeding structure 1210 is the first weight, and the weight of the powder in the set output of the fine feeding structure 1220 is the second weight. Since there are multiple fine feeding structures 1220, there are multiple second weights. It should be noted that the set weight here is a range value.

[0070] The preparation steps are as follows:

[0071] 1. The coarse feeding structure 1210 adds the first weight of medicinal powder into the cartridge 1110;

[0072] 2. The weighing structure 1230 weighs the first weight of the powder. The weighing structure 1230 executes the corresponding configuration strategy to control the operation of the fine feeding structure 1220, the first top opening structure, and the second top opening structure 1240.

[0073] The configuration strategy is as follows:

[0074] If the first weight is greater than the set weight, the first opening structure will activate to pour the powder in the cartridge 1110 into the waste bin. Since the coarse feeding structure 1210 and the fine feeding structure 1220 can only add powder to the cartridge 1110, if the cartridge 1110 exceeds the set weight range after the powder is added by the coarse feeding structure 1210, then the powder in the cartridge 1110 cannot be added to the medicine bag and can only be poured into the waste bin for recycling.

[0075] If the first weight is equal to the set weight, the second opening structure 1240 will activate to pour the powder in the medicine cartridge 1110 into the medicine bag. As can be seen from the above, the set weight is a range value. The first weight will also vary due to the existence of error. However, if the first weight is already within the range of the set weight, there is no need to add powder again. The powder in the medicine cartridge 1110 can be directly added into the medicine bag.

[0076] If the sum of the first weight and at least one second weight is greater than the set weight, the fine feeding structure 1220 will not operate, and the first top opening structure will operate to pour the powder in the cartridge 1110 into the waste bin. It should be noted that this scheme is unlikely to exist in actual practice, but it needs to be preset in the program settings to ensure the stable operation of the configuration device.

[0077] If the sum of all the second weights plus the first weight is still less than the set weight, the fine feeding structure 1220 will not operate, and the first opening structure will operate to pour the powder in the cartridge 1110 into the waste bin. That is, if the coarse feeding structure 1210 adds too little powder to the cartridge 1110, even if each fine feeding structure 1220 adds powder to the cartridge 1110, it will not be possible to reach the set weight of powder in the cartridge 1110. Therefore, there is no need to add more powder to the cartridge 1110. Instead of adding powder, you can simply pour out the powder inside the medicine cylinder 1110. For example, the dispensing device 1000 in this embodiment has four fine feeding structures 1220. Since the medicine cylinder 1110 cannot reach the set weight even if the subsequent four fine feeding structures 1220 add powder to the medicine cylinder 1110 after the powder is added to the coarse feeding structure 1210, there is no need to add powder to the medicine cylinder 1110. Pouring out the powder directly can improve efficiency.

[0078] If the first weight is less than the set weight, the sum of the first weight and at least one second weight is calculated so that the sum of the first weight and at least one second weight equals the set weight. Specifically, when the first weight is less than the set weight, the control module calculates the weight of the powder that the dispensing device 1000 can add to the medicine bag under various schemes and selects the most suitable scheme. For example, this embodiment has four fine feeding structures 1220. For ease of understanding, they are defined here as the first fine feeding structure 1220, the second fine feeding structure 1220, the third fine feeding structure 1220, and the fourth fine feeding structure 1220. The set output amount of the powder in the first fine feeding structure 1220 is the second weight A, and the set output amount of the powder in the second fine feeding structure 1220 is the second weight A. The weight of the powder in the first feeding structure 1110 is the second weight (C) and the weight of the powder in the second feeding structure 1220 is the second weight (D). If the first weight plus the second weight (A) equals the set weight, then the powder in the cartridge 1110 only needs to be added under the first feeding structure 1220. If the sum of the first weight and the second weights (A and D) equals the set weight, then the powder in the cartridge 1110 needs to be added under both the first and fourth feeding structures 1220. If the first weight plus the second weight (A) equals the set weight, and the sum of the first weight and the second weights (B and C) also equals the set weight, then the option with fewer feeding steps is preferred, or either option can be randomly selected.

[0079] It should be noted that the single discharge volume of the coarse feeding structure 1210 will be adjusted according to the actual situation. When the system finds that the powder weighing results of multiple consecutive cartridges 1110 all need to be replenished through the same fine feeding structure 1220, for example, after four or five cartridges 1110 have added the first weight of powder through the coarse feeding structure 1210, the first weight A of powder needs to be added through the first fine feeding structure 1220 after weighing calculation, then the quantitative adjustment structure 1212 of the coarse feeding structure 1210 will be adjusted appropriately to increase the set discharge volume of the coarse feeding structure 1210; when the system finds that the first weight of multiple consecutive cartridges 1110 exceeds the set weight, the quantitative adjustment structure 1212 of the coarse feeding structure 1210 will be adjusted appropriately to reduce the set discharge volume of the coarse feeding structure 1210.

[0080] According to the first aspect of the present invention, the dispensing device 1000, by providing a coarse feeding structure 1210 and a fine feeding structure 1220, with the fine feeding structure 1220 disposed after the coarse feeding structure 1210, is used to accurately add medicine powder into the medicine cartridge 1110 after the medicine powder has been added by the coarse feeding structure 1210, thereby improving the accuracy of medicine weighing; by using the weighing structure 1230, the first top opening structure and the second top opening structure 1240, medicine powder in the medicine cartridge 1110 that does not conform to the set weight can be removed, thereby improving the yield of medicine packs; according to the second aspect of the present invention, the dispensing method can more accurately weigh the appropriate weight of medicine powder, and at the same time avoids pouring medicine powder exceeding the weight into the medicine pack, thereby effectively improving the accuracy of medicine powder weighing, and thus improving the yield of medicine packs.

[0081] Reference Figure 1 As shown, the medicine bag filling equipment of the third aspect embodiment of the present invention includes a conveyor belt 2000, a feeding device 3000, a filling device 4000, a weighing device 5000, a rejection device 6000, and the above-mentioned batching device 1000; the conveyor belt 2000 is used to transport medicine bags, and the filling device 4000, the weighing device 5000, and the rejection device 6000 are arranged sequentially along the conveying direction of the conveyor belt 2000. The filling device 4000 is used to fill the medicine bags on the conveyor belt 2000 with medicine powder, the weighing device 5000 is used to weigh the medicine bags after filling with medicine powder, and the rejection device 6000 rejects medicine bags that do not meet the set weight from the conveyor belt 2000 according to the weighing result of the weighing device 5000; the feeding device 3000 is used to supply medicine bags to the conveyor belt 2000, and the batching device 1000 is used to transport the set weight of medicine powder to the filling device 4000.

[0082] In an embodiment of the present invention, reference is made to Figure 1As shown, the medicine bag has a filling port for filling it with medicine powder. A limiting structure 2100 is provided on the conveyor belt 2000 to limit the position of the medicine bag, while also ensuring that the filling port is facing upwards. A weighing device 5000 is located below the conveyor belt 2000. The weighing device 5000 simultaneously weighs the limiting structure 2100 and the medicine bag. By presetting the weight of the limiting structure 2100, the weight of the medicine bag can be obtained.

[0083] In an embodiment of the present invention, reference is made to Figure 1 As shown, the feeding device 3000 includes a horizontal sliding structure, a vertical lifting structure, and grippers. The grippers are installed on the vertical lifting structure, which is installed on the horizontal sliding structure. The grippers are used to pick up medicine packets from the medicine packet storage and place them on the conveyor belt 2000. A waste bin is located at a corresponding position of the waste rejection structure. The waste rejection structure also includes a horizontal sliding structure, a vertical lifting structure, and a gripping device. The gripping device is installed on the vertical lifting structure, which is installed on the horizontal sliding structure. The gripping device is used to pick up medicine packets. The waste rejection structure is used to pick up medicine packets that do not meet the weight requirements from the conveyor belt 2000 and transfer them to the waste bin.

[0084] In an embodiment of the present invention, the filling device 4000 includes a bag-supporting structure 4100 and a funnel structure 4200. The bag-supporting structure 4100 is disposed at the lower part of the funnel structure 4200. The bag-supporting structure 4100 is connected to a first lifting structure 4120 that drives its operation, and the funnel structure 4200 is connected to a second lifting structure 4210 that drives its operation. Specifically, refer to... Figure 5 , Figure 6 As shown, the bag support structure 4100 is used to open the filling port of the medicine bag so that the bottom of the funnel structure 4200 is aligned with the filling port of the medicine bag to fill the medicine bag, thereby effectively preventing the medicine powder from scattering during filling and causing insufficient weight of medicine powder in the medicine bag.

[0085] Reference Figure 6 As shown, in an embodiment of the present invention, the bag-supporting structure 4100 includes two clamping rods 4110 that can slide horizontally relative to each other, and the ends of the clamping rods 4110 are provided with pins 4111. When the filling device 4000 fills the medicine bag, the two clamping rods 4110 first move towards each other to a position where they contact each other, then the pins 4111 of both clamping rods 4110 are inserted into the filling port of the medicine bag, and then the two clamping rods 4110 slide in opposite directions to drive the pins 4111 to open the filling port. The first lifting structure 4120 is used to drive the bag-supporting structure 4100 to lift and lower, and correspondingly, the second lifting structure 4210 is used to drive the funnel structure 4200 to lift and lower. The first lifting structure 4120 and the second lifting structure 4210 can adopt structures such as telescopic cylinders and telescopic hydraulic cylinders.

[0086] It should be noted that when the two clamping rods 4110 slide back to back to the end position, the distance between the two clamping rods 4110 should be greater than the diameter of the bottom of the funnel structure 4200, so as to ensure that the bottom of the funnel structure 4200 can be inserted into the medicine bag.

[0087] The filling process of the filling device 4000 is as follows:

[0088] 1. The first lifting structure 4120 drives the bag support structure 4100 to descend, and at the same time, the two clamping rods 4110 of the bag support structure 4100 move towards each other to the contact position.

[0089] 2. After the bag support structure 4100 descends to the set position, the two insert rods are inserted into the filling port of the medicine bag. At this time, the two clamping rods 4110 slide in opposite directions, driving the two inserting pins 4111 to move synchronously to open the filling port of the medicine bag.

[0090] 3. After the two clamping rods 4110 slide back to back to the end position, the second lifting structure 4210 drives the funnel structure 4200 to descend to the bottom of the funnel structure 4200 and insert it into the filling port of the medicine bag. Then the funnel structure 4200 pours medicine powder into the medicine bag.

[0091] 4. After the filling is completed, the second lifting structure 4210 drives the funnel structure 4200 to reset upwards, the first lifting structure 4120 drives the bag support structure 4100 to reset upwards, and the two clamping rods 4110 of the bag support structure 4100 move towards each other to reset.

[0092] In an embodiment of the present invention, reference is made to Figure 5 As shown, the filling device 4000 also includes a first mounting frame 4500 and a third lifting structure 4300. The third lifting structure 4300 is mounted on the first mounting frame 4500, and the first lifting structure 4120 and the second lifting structure 4210 are both mounted on the third lifting structure 4300. The third lifting structure 4300 includes a guide rod 4310, a lifting plate 4320, and a lead screw 4330. The guide rod 4310 is vertically arranged, and the lifting plate 4320 is movably and vertically mounted on the guide rod 4310. The lead screw 4330 passes through the lifting plate 4320 and is connected to the lifting plate 4320 in a transmission manner. One end of the lead screw 4330 is provided with a rotating handle 4331. Rotating the rotating handle 4331 can drive the lead screw 4330 to rotate around its own axis, thereby driving the lifting plate 4320 to slide and rise along the guide rod 4310. The mounting plate 4321 is mounted on the lifting plate 4320, and the first lifting structure 4120 and the second lifting structure 4210 are both mounted on the mounting plate 4321. Rotating the handle 4331 causes the lifting plate 4320 to rise and fall, which in turn causes the bag support structure 4100 and the funnel structure 4200 to rise and fall synchronously, thus adapting to the filling of medicine bags of different specifications.

[0093] In an embodiment of the present invention, the filling device 4000 further includes a fourth lifting structure 4410 and an intermediate funnel 4400. The fourth lifting structure 4410 is mounted on the mounting plate 4321, and the intermediate funnel 4400 is mounted on the fourth lifting structure 4410. The fourth lifting structure 4410 is used to drive the intermediate funnel 4400 to lift. The intermediate funnel 4400 is mounted above the funnel structure 4200 and is used to guide the powder in the cartridge 1110 into the funnel structure 4200. (See reference...) Figure 5 As shown, a notch is provided on the outer periphery of the intermediate funnel 4400. This notch is used to prevent obstruction when switching the sealing structure 1111 at the bottom of the cartridge 1110 between the first and second positions. Since the required height of the funnel structure 4200 may vary slightly for different sizes of medicine packs, for example, some medicine packs may require the funnel structure 4200 to descend further, which might cause the powder inside the cartridge 1110 to scatter onto the outer periphery of the funnel structure 4200; or some medicine packs may require the funnel structure 4200 to descend less, which might affect the switching of the sealing structure 1111 from the first to the second position, thus preventing some powder from completely falling out of the cartridge 1110. The intermediate funnel 4400 and the fourth lifting structure 4410 effectively avoid these problems.

[0094] In an embodiment of the present invention, the medicine bag filling equipment further includes a sealing device 7000, which is disposed behind the filling device 4000 along the conveying direction of the conveyor belt 2000; the sealing device 7000 is used to seal the medicine bag. Specifically, refer to... Figure 1 As shown, the sealing device 7000 is located on one side of the conveyor belt 2000. The sealing device 7000 is mainly used to seal the filling port of the medicine package, thereby ensuring that the powder inside the medicine package will not scatter during subsequent conveying. Along the conveying direction of the conveyor belt 2000, the sealing device 7000 is located behind the rejecting device 6000. That is, the medicine packages are filled first, then weighed, and after weighing, unqualified medicine packages are rejected. Only qualified medicine packages require the sealing device 7000 to seal the filling port.

[0095] In an embodiment of the present invention, reference is made to Figure 7 , Figure 8As shown, the sealing device 7000 includes a dispensing machine 7130 and a clamping structure 7140. The dispensing machine 7130 is used to dispense adhesive at the filling port of the medicine package, and the clamping structure 7140 is used to clamp the filling port of the medicine package to facilitate adhesive solidification and prevent adhesive from entering the medicine package. The clamping structure 7140 includes two opposing clamping arms that can slide relative to each other. The dispensing machine 7130 is positioned in the middle of the two clamping arms and is connected to a first driving member 7131 that drives its lifting and lowering. The clamping structure 7140 is connected to a second driving member 7141 that drives its lifting and lowering. During dispensing, the clamping structure 7140 first descends to clamp the filling port of the medicine package, and then the dispensing machine 7130 descends to dispense adhesive at the filling port of the medicine package.

[0096] In an embodiment of the present invention, reference is made to Figure 7 , Figure 8 As shown, the sealing device 7000 includes a second mounting bracket 7100, on which a first slide rail 7110 and a second slide rail 7120 are provided. The length extension direction of the first slide rail 7110 is perpendicular to the length extension direction of the second slide rail 7120, and the length extension directions of the first slide rail 7110 and the second slide rail 7120 are both horizontal. A first slide block 7111 is slidably mounted on the first slide rail 7110, and a second slide block 7121 is slidably mounted on the second slide rail 7120. The second slide rail 7120 is disposed on the first slide block 7111, and a first driving member 7131 is mounted on the second slide block 7121. A second driving member 7141 is mounted on the second mounting bracket 7100.

[0097] Reference Figure 7 , Figure 8As shown, the second mounting bracket 7100 is also equipped with a first motor 7112 and a second motor 7122. The output end of the first motor 7112 is connected to a first transmission rod 7113, which is connected to the first slide block 7111. The output end of the second motor 7122 is connected to a second transmission rod 7123, which is connected to the second slide block 7121. The first motor 7112 drives the first transmission rod 7113 to rotate, which can drive the first slide block 7111 to slide along the first slide rail 7110. The second motor 7122 drives the second transmission rod 7123 to rotate, which can drive the second slide block 7121 to slide along the second slide rail 7120. The length extension direction of the first slide rail 7110 is perpendicular to the conveying direction of the conveyor belt 2000, and the length extension direction of the second slide rail 7120 is parallel to the conveying direction of the conveyor belt 2000. Therefore, the first motor 7112 drives the first slide block 7111 to slide along the first slide rail 7110, which in turn causes the dispensing machine 7130 to move closer to or further away from the medicine bag. Meanwhile, the second motor 7122 drives the second slide block 7121 to slide along the second slide rail 7120, which in turn causes the dispensing machine 7130 to slide along the length direction of the filling port of the medicine bag. This ensures that dispensing can be applied to all positions at the filling port of the medicine bag, thereby improving the bonding effect on the medicine bag. Through the sliding of the first slide block 7111, the sliding of the second slide block 7121, and the action of the first driving member 7131, the dispensing machine 7130 of this embodiment can be used for medicine bags of various specifications.

[0098] It is conceivable that the first slide 7111 and the second slide 7121 can also be replaced by telescopic hydraulic cylinders or telescopic air cylinders. However, the solution of driving the slides to slide through a transmission rod can achieve more precise control over the sliding distance of the dispensing machine 7130 compared to the solution of telescopic hydraulic cylinders or telescopic air cylinders, thereby reducing glue leakage or misalignment and improving the dispensing effect.

[0099] In an embodiment of the present invention, the medicine bag filling equipment further includes a feeding device. Along the conveying direction of the conveyor belt 2000, the feeding device is located behind the sealing device 7000. The feeding device is used to grab the medicine bags on the conveyor belt 2000 and move them to the next station.

[0100] The medicine bag filling equipment according to embodiments of the present invention can realize automated filling of medicine bags, improve filling efficiency, and reduce labor costs. By feeding the medicine powder to the filling device 4000 through the above-mentioned dispensing device 1000, the accuracy of the medicine powder weight can be effectively improved, thereby improving the yield of medicine bags. By setting up a weighing device 5000 to re-weigh the medicine bags and setting up a rejection device 6000 to reject medicine bags that do not meet the weight requirements, the yield of medicine bags is further improved. At the same time, since the medicine bag filling equipment includes the above-mentioned dispensing device 1000, it has at least all the beneficial effects of the dispensing device 1000, which will not be elaborated here.
