The dispensing system has a simple structure, and through the cooperation of the dispensing part and the receiving part, the materials stored in different storage containers can be discharged into the packaging container in turn to realize dispensing, and the weighing sensor can be used to weigh the storage container to accurately obtain the weight of the materials in the storage container. The weight of the storage container is measured before and after dispensing, and the weight difference is compared to determine whether there is a missing dispensing condition. The materials are quantitatively discharged into each packaging container, and when the dispensing is accurate (i.e. no missing materials, and each packaging container is accurately dispensed), the weight difference of the storage container before and after dispensing is a certain value. As long as the weight difference of the storage container is less than a preset value, it can be determined that there is a missing dispensing condition, and the packaging container can be checked in time to supplement the missing materials.

[0011] Further, at least two groups of the receiving parts are provided, and different receiving parts are arranged to be matched with the material dispensing part to dispense materials in turn, wherein when one receiving part is matched with the material dispensing part to dispense materials, the other receiving part can be arranged to perform the placing operation of the packaging container, the sealing operation of the packaging container and the taking-out operation of the packaging container, that is, the process of placing a new packaging container on the receiving part and the process of sealing and taking out the packaging container containing materials can be performed simultaneously with the process of dispensing materials from the material dispensing part into the packaging container on the receiving part, so that the operation efficiency can be greatly improved, the idle waiting time of each device can be reduced, and the material dispensing efficiency can be improved.

[0012] Further, the receiving parts are switched in position by the moving mechanism to be matched with the material dispensing part in turn, so that the structure is simple and easy to implement, the receiving parts are switched between the material dispensing position and the bag placing / taking-out position by the moving mechanism, and the operation efficiency is improved.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The dispensing system for ingredients disclosed in the embodiments of the present application has simple structure, is easy to implement, has good stability and high reliability in dispensing and releasing, can conveniently judge whether there is a missing release condition, and can flexibly adjust the dispensing mode according to needs.

[0029] As Figures 1 to 3As shown, a dispensing system for a dispensing machine, comprising a dispensing part 1 and a receiving part 2, the dispensing part 1 is provided with a plurality of storage containers 11, the lower part of the storage containers 11 is provided with a dispensing mechanism 12 for dispensing medicine, the dispensing part 1 is also provided with a weighing sensor 13 for weighing the storage containers 11, the receiving part 2 is provided with a plurality of stations 21, each station 21 is respectively provided with a container site 211 for placing a packaging container, the dispensing part 1 and the receiving part 2 are relatively movable, so that each station 21 of the receiving part 2 is alternately aligned with each storage container 11 of the dispensing part 1 to dispense medicine into the packaging container. The dispensing system of the embodiment uses the weighing sensor 13 to weigh the storage containers 11 before and after dispensing medicine, to determine whether there is a situation of missing dispensing medicine, when the dispensing of medicine is accurate, the weight loss value of the storage container will be consistent with the preset value, and when there is missing dispensing of medicine, the weight loss value of the storage container will be less than the preset value, so that the existence of missing dispensing of medicine can be accurately determined, the packaging container can be checked in time, the missing medicine can be supplemented, and the safety and reliability of medication can be ensured.

[0030] The dispensing and dispensing unit 1 is equipped with several storage containers 11, each of which can store different types of medicines. When a station 21 is aligned with a storage container 11, the medicine in the storage container 11 is fed into the packaging container in the station 21 through the feeding mechanism 12. Then, the dispensing and dispensing unit 1 and the receiving unit 2 move relative to each other, so that the alignment relationship between the station 21 and the storage container 11 changes to achieve alternating alignment. That is, the storage container 11 is aligned with another different station 21, so that the medicine in the storage container 11 is fed into the packaging container in the other station 21 through the feeding mechanism 12. More specifically, at the beginning of the dispensing process, storage container 11 is positioned opposite station 21, storage container 11 is positioned opposite station 21, and so on. The first medicine in storage container 11 is fed into the packaging container in station 21 via the feeding mechanism 12, and the second medicine in storage container 11 is fed into the packaging container in station 21 via the feeding mechanism 12. After the first dispensing, each packaging container contains only one medicine. Then, the dispensing and receiving department 1 and the receiving department... 2. The relative movement of the two changes the alignment between workstation 21 and storage container 11, so that storage container 11 is aligned with workstation 21, storage container 21 is aligned with workstation 3, and so on. Medicine No. 1 in storage container 11 is fed into the packaging container in workstation 21 via feeding mechanism 12, and medicine No. 2 in storage container 11 is fed into the packaging container in workstation 3 via feeding mechanism 12. After the second dispensing, each packaging container contains two medicines. This process repeats, allowing each workstation 21 of receiving unit 2 to be aligned with each storage container 11 of dispensing and dispensing unit 1 in turn. In other words, the relative movement of dispensing and dispensing unit 1 and receiving unit 2 allows each workstation 21 to be aligned sequentially with all storage containers 11, so that the packaging container at each workstation 21 sequentially receives the medicine fed from each storage container 11 until the required medicine is dispensed.

[0031] The relative movement of the dispensing and mixing unit 1 and the receiving unit 2 can be either that the dispensing and mixing unit 1 is active while the receiving unit 2 is stationary, or that the dispensing and mixing unit 1 is stationary while the receiving unit 2 is active. In this embodiment, the dispensing and mixing unit 1 is stationary while the receiving unit 2 is active, so that each station 21 of the receiving unit 2 and each storage container 11 of the dispensing and mixing unit 1 are alternately aligned. More specifically, the storage containers 11 are arranged circumferentially on the dispensing and mixing unit 1, and the weighing sensor 13 is located at the center of the circle where the storage containers 11 are distributed. The structure is simple, compact, easy to implement, and low in cost. Before and after dispensing the medicine, the storage containers 11 are placed on the weighing sensor 13 for weighing and measurement, and the weight change is recorded. Then, the weight change is used to determine whether there is any missed dispensing of medicine. Alternatively, each storage container 11 on the dispensing and mixing unit 1 can be weighed in real time by a weighing sensor 13 to obtain the weight of each storage container 11 in real time, thereby determining whether there is any missed dispensing of medicine. In this embodiment, the workstations 21 are arranged circumferentially on the receiving unit 2. When dispensing medicine, at least some of the workstations 21 on the receiving unit 2 are aligned with a storage container 11 at the same time to dispense medicine simultaneously. That is, at a certain moment when dispensing medicine, at least one storage container 11 is aligned with one workstation 21, and another storage container 11 is aligned with another workstation 21, thereby realizing many-to-many medicine dispensing, that is, multiple medicines are simultaneously dispensed into the packaging containers of different workstations 21, effectively improving the dispensing efficiency. Then, the receiving unit 2 rotates relative to the dispensing and mixing unit 1, so that the alignment relationship between the workstations 21 and the storage containers 11 is switched, and finally the multiple medicines are dispensed into the respective packaging containers. Preferably, the number and distribution of storage containers 11 on the dispensing and dispensing section 1 are the same as the number and distribution of workstations 21 on the receiving section 2. When dispensing medicine, the workstations 21 and storage containers 11 are aligned one-to-one. That is, the circumferential radius of the distribution of storage containers 11 is the same as the circumferential radius of the distribution of workstations 21, and the circumferential spacing of storage containers 11 is the same as the circumferential spacing of workstations 21. Thus, when dispensing medicine, each storage container 11 has a corresponding workstation 21. In each round of medication dispensing, the medication in each storage container 11 can be placed into the packaging container of the corresponding workstation 21. Assuming the number of storage containers is N, where N≥1, the number of workstations 21 is also N, allowing for the simultaneous dispensing of N medications. Neither storage container nor workstation 21 is idle, thus improving operational efficiency. The receiving unit 2 rotates N times relative to the dispensing and adjusting unit 1, enabling each workstation 21 to take turns aligning with each storage container 11, thereby dispensing all N medications into the packaging container of each workstation 21, effectively improving medication dispensing efficiency.Of course, the number of storage containers 11 on the dispensing and dispensing section 1 can be different from the number of workstations 21 on the receiving section 2. The number of storage containers 11 on the dispensing and dispensing section 1 can be greater than the number of workstations 21 on the receiving section 2, or the number of storage containers 11 on the dispensing and dispensing section 1 can be less than the number of workstations 21 on the receiving section 2. In either case, the relative movement between the dispensing and dispensing section 1 and the receiving section 2 can be used to make each workstation 21 of the receiving section 2 and each storage container 11 of the dispensing and dispensing section 1 take turns to be aligned, and finally complete the dispensing of all medicines according to the demand.

[0032] In this embodiment, when dispensing medicine, the receiving unit 2 moves to be located directly below the medicine dispensing unit, and the center of the distribution of storage containers 11 coincides with the center of the distribution of workstations 21. Thus, when dispensing medicine, the medicine in each storage container falls vertically into the packaging container below after passing through the feeding mechanism 12. The dispensing and distribution is convenient and highly reliable. The receiving unit 2 only needs to rotate relative to the dispensing and dispensing unit 1 to make each workstation 21 align with each storage container in turn, thereby efficiently dispensing all the medicines into each packaging container.

[0033] Furthermore, such as Figures 5 to 7As shown, the feeding mechanism 12 includes several feeding channels 121, and each station 21 of the receiving unit 2 includes several container positions 211. Each container position 21 of the receiving unit 21 corresponds one-to-one with a feeding channel 121, so that multiple packaging containers can be placed on each station 21 at the same time. Thus, each storage container 11 can be dispensed into multiple packaging containers on the corresponding station 21 at one time through the feeding mechanism 12, thereby improving dispensing efficiency and increasing the amount of medicine dispensed at one time. More preferably, the feeding channels 121 can be selectively opened and closed, that is, the opening and closing status of each feeding channel 121 can be selectively controlled. Specifically, each feeding channel 121 can be equipped with a valve to flexibly and independently control the opening and closing of each feeding channel 121, or a portion of the feeding channels 121 can be opened and closed together. Thus, the feeding mechanism 12 can have a variety of different feeding methods to flexibly meet different feeding needs. When all feeding channels 121 are open, medication can be dispensed to all packaging containers at workstation 21. When only a portion of the feeding channels 121 are open, medication is dispensed to only a portion of the packaging containers at workstation 21. This provides good flexibility and adjustability, flexibly meeting the medication needs of different prescriptions. For example, if a prescription contains N doses of medication (N≥2), and only L doses contain a specific ingredient (L<N), then the medication can be selectively dispensed to only a portion of the packaging containers by controlling the opening and closing of the feeding channels 121. Alternatively, some workstations 21 in the receiving section 2 can have only a portion of the container positions 211 filled with packaging containers, enabling different medication dispensing schemes for odd and even days. For example, odd-numbered days may have more doses (three or four doses), while even-numbered days may have fewer doses (two or one dose). By adjusting each feeding mechanism 12, medication can be flexibly dispensed to the corresponding number of packaging containers at each workstation 21. In this embodiment, the feeding mechanism 12 has four feeding channels 121, and each station 21 has four corresponding container positions 211, such as... Figure 5 As shown, the feeding channels 121 of the feeding mechanism 12 can be fully opened, forming a four-to-four dispensing mode to simultaneously dispense medicine to all packaging containers on all container positions 211 of each station 21; as Figure 6 As shown, the feeding channel 121 of the feeding mechanism 12 can also be opened only in two places, thus forming a two-to-two drug dispensing mode, where the drug is dispensed to the packaging containers on the two container positions 211 of the workstation 21 at the same time.

[0034] Specifically, such as Figure 7As shown, the feeding mechanism 12 includes a first feeding component 122 and a volumetric layer 123. The first feeding component 122 is provided with a plurality of first feeding holes 1211. In this embodiment, there are specifically four first feeding holes 1211. The first feeding holes 1211 are distributed circumferentially on the first feeding component 122. The volumetric layer 123 is rotatably disposed relative to the first feeding component 122, that is, the volumetric layer 123 can rotate relative to the first feeding component 122. The volumetric layer 123 is provided with four volumetric holes 1212 with preset volumes. The volumetric holes 1212 are distributed circumferentially on the volumetric layer 123, and the volumetric holes 1212 have the same volume. The feeding channel 121 is mainly formed by the cooperation of the first feeding holes 1211 and the volumetric holes 1212. The structure is configured such that when the volume holes 1212 are connected to the storage container 11, each volume hole 1212 stores a predetermined volume of medicine. The volume layer 123 has a first preset position and a second preset position. When the volume layer 123 rotates relative to the first feeding member 122 to the first preset position, each volume hole 1212 is connected to the corresponding first feeding hole 1211, so that the medicine in each volume hole 1212 is discharged through the corresponding first feeding hole 1211. When the volume layer 123 rotates to the second preset position, the connection between each volume hole 1212 and the corresponding first feeding hole 1211 is disconnected. At this time, the volume holes 1212 and the first feeding holes 1211 are not connected, and the entire feeding mechanism is in a non-feeding state. When the volume layer 123 is in the first preset position, the multiple first feeding holes 1211 are arranged one-to-one with the multiple volume holes 1212, and feeding is performed respectively.

[0035] Furthermore, the feeding mechanism 12 also includes a stop 124, which is rotatably configured relative to the first feeding member 122. When the stop 124 rotates to a certain position, it can block a portion of the first feeding holes 1211 on the first feeding member 122, preventing the blocked first feeding holes 1211 from feeding, while the unblocked first feeding holes 1211 feed normally. In other words, the stop 124 selectively controls the opening and closing of the feeding channel 121 as needed, allowing the feeding mechanism 12 to feed the same number of medicines as the volume holes 1212 or less than the number of medicines in the volume holes 1212, making the application more flexible and convenient. Specifically, the stop 124 is a rotating end cap with four circumferentially distributed discharge holes. The stop 124 rotates and switches between a third preset position and a fourth preset position. When the baffle 124 rotates to the third preset position, the four discharge holes on the baffle 124 correspond one-to-one with the first discharge holes 1211 on the first discharge component 122 and are connected to each other, so that all four discharge channels 121 are open and each discharge channel 121 can discharge normally, thus forming a four-to-four dispensing mode. When the baffle 124 rotates to the fourth preset position, only two discharge holes of the baffle 124 correspond to and are connected to the first discharge holes 1211 on the first discharge component 122, and the other two first discharge holes 1211 on the first discharge component 122 are blocked and closed, so only two discharge channels 121 can discharge normally, thus forming a two-to-two dispensing mode.

[0036] Furthermore, the feeding mechanism 12 also includes a second feeding component 125. The second feeding component 125 is disposed on the side of the volume layer 123 away from the first feeding component 122, and is also used to connect with the storage container 11. Specifically, the second feeding component 125 is provided with a threaded opening for threaded connection with the opening of the storage container 11, realizing a detachable connection between the feeding mechanism 12 and the storage container 11. The second feeding component 125 is provided with four second feeding holes 1213. When the second feeding component 125 is connected to the storage container 11, the second feeding holes 1213 are in a state of communication with the interior of the storage container 11. The four second feeding holes 1213 are distributed circumferentially on the second feeding component 125, and the four second feeding holes 1213 are arranged one-to-one with the four volume holes 1212. Moreover, the volume layer 123 is rotatably disposed relative to the second feeding component 125. This means that the volume layer 123 can rotate relative to the second feeding component 125. The volume layer 123 has a fifth preset position and a sixth preset position. When the volume layer 123 rotates to the fifth preset position, each second feeding hole 1213 is connected to the corresponding volume hole 1212 for feeding. When the volume layer 123 rotates to the sixth preset position, the second feeding hole 1213 is not connected to the corresponding volume hole 1212. Furthermore, while the volume layer 123 rotates to the sixth preset position to connect the second feeding hole 1213 with the volume hole 1212, the feeding hole 431 is not connected to the first feeding hole 1211. This avoids the situation where the second feeding hole 1213, the volume hole 1212, and the first feeding hole 1211 are connected at the same time, thus preventing the medicine in the storage container 11 from being fed in a quantitative manner and improving the accuracy and reliability of medicine dispensing.

[0037] The feeding mechanism 12 also includes a dispersing component, which is a rotating impeller 126. The impeller 126 is located on the side of the volume layer 123 away from the first feeding component 122, that is, the impeller 126 is located on the inlet side of the feeding channel 121. After absorbing moisture, the medicine is prone to clumping. The clumped medicine becomes larger in volume, making it difficult to pass through the second feeding hole 1213, the volume hole 1212 and the first feeding hole 1211. This seriously affects the reliability of medicine dispensing and makes it easier for medicine to be missed. Therefore, the rotating impeller 126 is used to stir and disperse the medicine, so that the clumped medicine is separated and restored to a normal state, which facilitates smooth medicine dispensing.

[0038] In this embodiment, the dispensing and adjusting unit 1 is in a stationary position while the receiving unit 2 rotates, so that each station 21 of the receiving unit 2 is alternately aligned with each storage container 11 of the dispensing and adjusting unit 1. Specifically, as shown... Figure 4As shown, the receiving unit 2 includes a large turntable 22 and a small turntable 212. Several small turntables 212 for forming workstations 21 are arranged on the large turntable 22 along its rotational circumference. The small turntables 212 are rotatably mounted on the large turntable 22 and have several container positions 211 for placing packaging containers arranged along their own rotational circumference. The large turntable 22 rotates as a whole under the drive of the drive mechanism, thereby causing the small turntables 212 forming the workstations 21 to revolve around the large turntable 22. Furthermore, the small turntables 212 forming the workstations 21 can also rotate on the large turntable 22, thereby enabling the rotation and switching of the positions of each container position 211 on the small turntable 212. During medication dispensing, the large turntable 22 rotates as a whole under the drive mechanism, that is, the receiving unit 2 rotates relative to the dispensing and mixing unit 1, so that each station 21 of the receiving unit 2 is aligned with each storage container 11 of the dispensing and mixing unit 1. Then, each storage container 11 puts medicine into the packaging container on all or more container positions 211 of the corresponding station 21 through the feeding mechanism 12. Then the large turntable 22 rotates again to change the alignment relationship between the station 21 of the receiving unit 2 and the storage container 11 of the dispensing and mixing unit 1. Each storage container 11 puts medicine into the packaging container on all or more container positions 211 of the corresponding station 21 through the feeding mechanism 12 again. This cycle continues until each packaging container is filled with the required type and quantity of medicine. When placing the packaging containers, the large turntable 22 first rotates to position a small turntable 212 at the loading position. Then, the small turntable 212 in the loading position rotates, causing the container positions 211 to rotate to the loading position in turn. The packaging containers are then placed in the container positions 211 in the loading position. After the required number of packaging containers are placed on a small turntable 212, the large turntable 22 starts to rotate again to rotate the next small turntable 212 to the loading position. This process is repeated to ensure that the required number of packaging containers are placed on each small turntable 212. Similarly, this also facilitates sealing and removing the packaging containers after the medicine is dispensed.

[0039] The basic workflow of the dispensing machine includes placing the packaging container into the container position of station 21, dispensing the medicine from the storage container into the packaging container, sealing the packaged bag after dispensing, and removing it. When only a single receiving unit 2 is set up, the waiting time of each component is long, thus affecting the overall dispensing efficiency. For example, when the packaging container is placed into the container position 211 of station 21 of receiving unit 2, the dispensing and mixing unit 1 is in a waiting, non-working state. However, when the process of dispensing the medicine from the storage container into the packaging container is carried out, the process of placing the packaging container into the container position of station 21 also requires waiting. The long waiting idle time of each component of the dispensing machine results in low overall dispensing efficiency. Therefore, in this embodiment, the receiving unit 2 is provided in two sets. Different receiving units 2 take turns cooperating with the dispensing and distributing unit 1 to dispense medicines. Thus, when the dispensing and distributing unit 1 cooperates with the first set of receiving units 2 to dispense medicines, the second set of receiving units 2 can perform the process of placing the packaging container in the container position of the workstation 21 and sealing and removing the packaged container after medicine dispensing. Then, the first set of receiving units 2 and the second set of receiving units 2 take turns, and the dispensing and distributing unit 1 cooperates with the second set of receiving units 2 to dispense medicines. The first set of receiving units 2 can perform the process of placing the packaging container in the container position of the workstation 21 and sealing and removing the packaged container after medicine dispensing. This greatly improves work efficiency, reduces the idle waiting time of each device, and improves medicine dispensing efficiency.

[0040] In this embodiment, both sets of receiving units 2 are located in the area below the dispensing and mixing unit 1. The two sets of receiving units 2 are driven by a moving mechanism to switch positions and alternately cooperate with the dispensing and mixing unit 1. Specifically, the moving mechanism is a horizontal linear moving mechanism. The receiving units 2 are moved laterally by the moving mechanism to switch positions. When the receiving unit 2 is moved to the dispensing and mixing position directly below the dispensing and mixing unit 1, the receiving unit 2 cooperates with the dispensing and mixing unit to dispense the medicine. After the receiving unit 2 moves away from directly below the dispensing and mixing unit 1, it is moved to the bag-removing position. When the receiving unit 2 is in the bag-removing position, the process of placing the packaging container in the container position of the workstation 21 and sealing and removing the dispensed packaging bag can be performed. Alternatively, the moving mechanism can also adopt other structural forms, such as a rotating mechanism. Rotation can also achieve the switching between the dispensing and mixing positions of the two sets of receiving units 2, resulting in a simple structure that is easy to implement.

[0041] When dispensing medicine using the above-mentioned ingredient dispensing system, the dispensing prescription is input into the dispensing system. The storage containers 11 of the relevant medicines in the prescription are placed on the weighing sensors 13 for weighing measurement. The weighing data is entered into the dispensing system for storage. Then, the dispensing personnel place the weighed storage containers 11 in the corresponding positions on the dispensing and dispensing unit 1. After all the storage containers 11 are weighed and placed in place, the medicine dispensing starts. Each work station 21 is aligned with a storage container 11 respectively. By controlling the blanking mechanism 12, the medicines in each storage container 11 are respectively released into the packaging containers at the corresponding work stations 21. Then, the large turntable 22 of the receiving unit 2 rotates, causing the alignment status between the work stations 21 and the storage containers 11 to change alternately. Finally, the medicines in all the storage containers 11 are all dispensed into each packaging container. Finally, the storage containers 11 after the medicine dispensing is completed are placed on the weighing sensors 13 for weighing measurement. The dispensing system will compare the weighing data of the storage containers 11 before and after the medicine dispensing to determine whether there is any missed dispensing. When the number of medicine flavors in the prescription exceeds the number of storage containers 11 on the dispensing and dispensing unit 1, multiple rounds of medicine dispensing are carried out. For example, if the number of storage containers 11 is N and the number of medicine flavors is L, where N < L < 2N, then the first round of medicine dispensing for N flavors of medicine is carried out first, and then the second round of medicine dispensing for the remaining L - N flavors of medicine is carried out. When it is necessary to dispense medicine only to a part of the packaging containers on the work stations 21, the blanking mechanism 12 is adjusted to selectively open and close the blanking channels 121 to release the medicine into a part of the corresponding packaging containers.
