TECHNICAL FIELD
[0001] The utility model relates to the field of medical apparatus and instruments, and particularly relates to an automatic medicine dispensing system. BACKGROUND
[0002] Traditional Chinese medicine dispensing systems mostly adopt a mode of combining manual sorting with semi-automatic equipment, which has a significant efficiency bottleneck. The existing system architecture usually relies on a vibration discharge mechanism to perform a discharge action, and cooperates with a conveyor belt to complete medicine transfer, and its operation process needs to sequentially complete multiple serial links such as prescription receiving, medicine positioning, vibration discharge, and weighing calibration. Especially when facing the demand of concurrent processing of multiple prescriptions, since the conveyor belt can only sequentially transport medicines to complete prescription dispensing, some prescription dispensing falls behind, thereby affecting the dispensing efficiency of the whole system, and the overall throughput of the system is difficult to break through the single-thread operation mode.
[0003] For the above problems, no effective solution has been proposed so far. SUMMARY
[0004] The utility model embodiment provides a kind of automatic medicine dispensing system of medicine, to at least solve the technical problem of low work efficiency of medicine dispensing system in prior art.

In all examples shown and discussed herein, any specific values are to be interpreted as merely illustrative and not limiting. Other examples of the example embodiments can have different values. It is noted that like numbers and letters refer to like elements throughout the several views of the drawings and, as such, no further discussion with regard thereto is deemed necessary.
[0072] The present application provides an automatic medicine dispensing system, as shown in Figure 1 The system includes a medicine access cabinet 10, a dispensing robot 12, and a control system 14.
[0073] The medicine access cabinet will be described in detail below.
[0074] The existing medicine access cabinet is composed of multiple dispensing units installed obliquely, each dispensing unit is provided with a medicine adding port at the rear and a medicine dropping port at the lower front, multiple dispensing units share one medicine dropping channel, and the medicine dropping channel is uniformly conveyed to a medicine receiving frame through a conveying line or other equipment below. Since multiple dispensing units share one medicine dropping channel in the existing design, once there is residual medicine in the channel, it is easy to cause cross contamination between different dispensing prescriptions, thereby causing medical safety hazards.
[0075] The present application provides a medicine access cabinet, as shown in Figures 2 to 4 The medicine access cabinet includes a main frame 101 and multiple dispensing units 102.
[0076] The main frame 101 is hollow inside and includes an upper part and a lower part. The upper part is used to install and fix the dispensing units 102. The dispensing units 102 are distributed in multiple layers from top to bottom in the upper part, with each layer consisting of two rows facing each other and multiple columns from left to right. The lower part is located below the upper part and is fixedly connected to it, providing a passage for the dispensing trolley to travel. The dispensing trolley is used to receive the medicine output from the dispensing channel 105 of the corresponding dispensing unit 102. The lower part is provided with at least one dispensing port enclosure structure 104 to enclose the dispensing port of part or all of the dispensing channels 105 of the dispensing units 102. At least one side wall of each dispensing port enclosure structure 104 is provided with a dust removal pipe 103 for cleaning dust from the medicine falling from the dispensing port in the corresponding dispensing port enclosure structure 104.
[0077] The dispensing unit in the medicinal herb storage cabinet will be described in detail below. The dispensing unit includes a dispensing machine and a dispensing channel.
[0078] Existing discharge methods for material discharge machines include staggered tooth and brush discharge, vibration discharge, and single screw discharge. These methods generally suffer from problems such as material jamming, poor accuracy, low efficiency, and high cost. For example, when the external screw rotates, it needs to have a certain gap with the hopper wall, which leads to a significant risk of material jamming at the outlet.
[0079] To address the aforementioned problems, this utility model provides a discharge machine, such as... Figures 5 to 19 As shown, the feeding mechanism (e.g., screw) of this discharge machine does not have blades on the screw between its front end and the drum, or there is an axial gap between the front end of the screw and the drum. Thus, there is no rigid structure between the front end of the screw and the drum, forming a buffer zone, and the material in the screw pushes the material at the front end into the drum. Furthermore, the helical blades inside the drum are integral with the drum, without gaps. This structure solves the problem of material jamming in existing discharge machines.
[0080] like Figure 5 As shown, the discharging machine mainly includes a primary hopper 201, a dispensing mechanism 202, a weighing component 203, an isolation component 204, and a secondary hopper 205. The dispensing mechanism 202 includes a pushing mechanism and a roller. The discharging machine uses a screw or other pushing mechanism to transport materials, such as medicinal herbs, into the inside of the roller, and the rotation of the roller achieves quantitative output of the material. When the material accuracy requirement is not high, direct roller discharging can be performed; when the accuracy requirement is high, it can be used in conjunction with the weighing hopper of the weighing component 203 to achieve precise quantitative discharging.
[0081] Primary silo 201 Figure 6The main purpose of the shown is to store or buffer materials, in addition, also play a conveying material screw support the weight of the material, so that the majority of the weight of the material on the side wall of the first bin. The screw is directly above the direction of rotation of the screw is also covered by the first bin, so you can reduce the resistance of the material to the screw, improve the discharge accuracy, so as to reduce the driving force of the screw. For low density of light material, not too much support for the material, then you can use no need to cover the screw bin, such as Figure 7 The two structures have no obvious use limit, according to different working conditions, requirements, etc. can be used. Through the above structure, the existing regulating unit can solve the problem of card material, poor precision, low efficiency and high cost. The bin can be a whole bin, or two separate bins, for example, in addition to the first bin, also can include two bin 205, two bin 205 is to facilitate the material or facilitate automatic feeding.
[0082] The regulating mechanism includes a push mechanism and a drum, the push mechanism can be a screw, of course, can also be other push structure, the drum is the spiral blade and the outer wall of the drum together. The shape of the drum can be cylindrical, conical, or other as long as the output material of the middle of the shape. The drum can be placed horizontally with the screw, can also change the way, for example, inclined or vertical placement, or the drum into a drum bin integral manner.
[0083] To solve the problem of card material, poor precision, low efficiency and high cost, according to different materials, the drum and screw can adopt different forms, for example, the present application provides the following four structures.
[0084] Form one: hard screw and drum combination, the two are split structure, with different speed.
[0085] For example, Figure 8As shown, the hard screw 2022 is driven by the screw driving motor 2021 to deliver the material to the mouth position of the roller 2023 (i.e. the roller feeding position). At the mouth position, the front end of the hard screw 2022 is not connected with the roller, and the material at the mouth position is delivered to the inside of the roller in the form of material pushing. The roller driving motor 2024 drives the roller 2023 through the driving gear 2025, and the rotation of the roller 2023 quantitatively outputs the material. In this embodiment, the hard screw and the roller are driven asynchronously by two motors, so that the rotation speeds of the two are different. In other embodiments, one motor can be used to achieve power transmission and speed difference between the roller and the screw through different reduction arms. For some materials that may accumulate at the mouth of the roller, the roller is driven asynchronously with the screw, so that the rotation speed of the roller is greater than that of the screw. In this way, the material can be quickly delivered, thereby reducing the accumulation of the material. Of course, in other embodiments, the same motor can be used for synchronous driving, so that the rotation speeds of the two are the same.
[0086] Form two: soft screw combined with roller, which are separate structures and have different rotation speeds.
[0087] Considering that some materials may be stuck between the hard screw and the bin, the hard screw is replaced by a soft screw in this embodiment, as shown in Figure 9 The soft screw 2026 includes a screw and a flexible blade 2027 spirally arranged on the screw. When encountering material jam, the flexible blade 2027 will automatically deform to automatically remove the jam fault, so that it can continue to rotate. The driving form in this embodiment can be the same as that in form one, which will not be described here.
[0088] Form three: hard screw and roller are integrally formed and have the same rotation speed.
[0089] As shown in Figure 10 The blade of the hard screw or other means is connected with the inside of the roller to form a hard screw-roller integrated structure 2028 as a regulating mechanism. Under the action of the screw driving motor 2021, it rotates at a constant speed. This kind of hard screw-roller integrated structure 2028 only needs one driving force, the driving structure is simple, the integrated design and installation are more convenient, and the cost is reduced.
[0090] Form four: soft screw and roller are integrally formed and have the same rotation speed.
[0091] As shown in Figure 11As shown, the pushing mechanism is composed of a screw roller integration 2029 and a flexible blade 2027, wherein the screw roller integration 2029 is a screw roller and a roller fixed together through a fixing member. When the flexible blade 2027 encounters materials with blockage, the soft blade will be forced to deform, avoiding the materials from being stuck, and improving the stability of the device.
[0092] In the embodiment of the present application, the roller and the screw are combined to discharge materials, the screw conveys materials, and the roller quantitatively discharges materials, thereby solving the problem of material blockage. In other embodiments, in addition to the screw mode, the material conveying of the pushing mechanism can also be in other forms such as vibration and silo inclination, as long as the materials are conveyed into the roller, the purpose of discharging can be achieved.
[0093] As shown in the figure, Figure 12 The weighing assembly includes a weighing hopper 2033 and a weighing sensor 2035, wherein the side bottom of the weighing hopper 2033 is provided with a discharge plate 2034, which is rotatably connected with the body of the weighing hopper 2033 through a rotating shaft 2032. The weighing assembly is used in cooperation with the quantitative discharge under the condition that the material precision and efficiency are required to be high. When the discharge precision requirement is low, the screw roller quantitative discharge can be directly used without setting the weighing assembly. The use of the weighing assembly can improve the dispensing efficiency. When the instruction is received, the materials can be first conveyed into the weighing hopper, thereby saving the discharging time.
[0094] The materials are output from the screw and the roller into the weighing hopper 2033, the weight is accurately controlled by the weighing sensor 2035, and the weight is fed back to the control system in real time. When the real-time weight reaches the required weight of the prescription, the discharge plate 2034 is driven to rotate along the rotating shaft 2032 under the driving of the discharge plate motor 2031 (controlled by the control system), an opening is formed between the discharge plate 2034 and the body of the weighing hopper 2033, and the materials can fall into the medicine frame of the dispensing trolley below through the opening.
[0095] The dispensing unit in the embodiment of the present application further includes an isolation assembly 204, as shown in the figure, Figures 13 to 17As shown, the isolation assembly 204 can adopt various structures. In order to smoothly convey the material from the screw into the roller, so that the material is continuously and uniformly discharged, ensuring the accuracy, the embodiment of the application sets an isolation assembly 204 above the screw, i.e. in the first bin, which divides the first bin into upper and lower layers. The setting of the isolation assembly can reduce the resistance of the material to the screw on the one hand, and on the other hand, since the material will form a bridge in the first bin, the isolation assembly can destroy the bridge, so that the material falls uniformly on the screw below. Considering the actual effect and cost reasons, different materials need different types of isolation assemblies 204, and the power source can be a separate power drive, or a power drive can be used on the discharge machine through a transmission structure. In addition, the rotation mode of the isolation assembly 204 can also be relative to the inside rotation, relative to the outside rotation, or swing within a certain preset angle according to different materials. In this way, the orderly conveying of the material can be realized.
[0096] Mode one: as shown in Figure 13 and 14 , the isolation assembly 204 is installed on the first bin 201, the drive motor 2041 drives the isolation assembly mesh gear 2042 to rotate, the isolation shaft 2043 is installed with the isolation plate 2044, under the drive of the drive motor 2041, the two isolation shafts move in opposite directions, conveying the material falling on the isolation assembly 204 to the screw below, the rotation speed of the isolation assembly 204 is proportional to the material output by the screw below.
[0097] Mode two: as shown in Figure 15 , the isolation assembly 204 is installed in the width direction of the first bin 201, the drive motor 2041 drives the isolation assembly mesh gear 2042 to rotate, the blocking shaft 2045 is installed with the bridge breaking rod 2046, the blocking shaft 2045 rotates under the drive of the drive motor 2041, since the blocking shaft 2045 is installed just above the screw, it plays a supporting role to the material, thereby reducing the pressure of the material to the screw. The material will form a bridge during free falling, after the bridge is formed, the material cannot fall, and by rotating the isolation assembly 204, the bridge can be broken, so that the material falls.
[0098] Mode three: as shown in Figure 16As shown, the isolation assembly is installed in the length direction of the first material bin 201, and a blocking long shaft 2047 is directly driven by a driving motor 2041, and a bridge breaking rod 2046 is installed on the blocking long shaft 2047. The blocking long shaft 2047 rotates under the driving of the driving motor 2041, and is just installed above the screw rod to support the material and reduce the pressure of the material on the screw rod. The material will bridge in the process of free falling, and the material cannot fall after the bridge is formed. The rotation of the isolation assembly 204 can break the bridge to make the material fall. In this embodiment, the blocking long shaft 2047 is installed in the length direction of the first material bin, which is relatively installed in the width direction of the first material bin, and has the advantages of convenient power installation and space saving.
[0099] Mode four: as shown in Figure 17 and 18 shown, the isolation assembly is an arc-shaped isolation plate 2048, and a gap or a through hole is formed between the edge of the arc-shaped isolation plate 2048 and the side wall of the first material bin 201. The arc-shaped isolation plate 2048 is installed above the screw rod. This isolation mode is mainly used for materials with good flowability. The material flows along the arc surface to the screw rod below, and the isolation plate supports the weight of the material at the same time to reduce the resistance of the material to the screw rod.
[0100] In some embodiments, the dispensing unit can also include a second material bin 205 as shown in Figure 19 . The second material bin 205 is used to supplement the material of the first material bin 201 online and / or supplement the material in the off-peak period. If there is no second material bin 205, directly supplementing the material of the first material bin 201 when the system is working will spill out of the first material bin 201 or cause cross contamination. However, through the online automatic feeding of the second material bin 205, the above pollution problem can be solved and the operation is convenient. In addition, the number of second material bins is often more, and in the off-peak period, the standby second material bin is filled with material, and when needed, the empty second material bin is taken down, and the second material bin filled with material is installed, which also has the beneficial effect of online feeding.
[0101] Specifically, the second material bin 205 is composed of a bin body 2051, a bin bottom plate 2052 and a bin rotating shaft 2053. The bin bottom plate 2052 is installed at the bottom of the bin body 2051 to block the bin body 2051, so that the material in the bin body 2051 will not leak out. When the bin body 2051 has no material, the second material bin 205 is placed above the first material bin 201, the bin bottom plate 2052 is pulled out, and after being pulled out, the bin bottom plate 2052 rotates around the bin rotating shaft 2053 and is buckled. After the bin bottom plate 2052 is pulled out, an opening is formed at the bottom of the bin body 2051, and the material falls from the second material bin 205 into the first material bin 201 below to realize feeding. This feeding method is simple and easy to operate, and the material will not be scattered outside to cause cross contamination during the feeding process.
