Technical Field

[0002] Currently, general automatic injectable medicine dispensing machines usually use multi-axis manipulators to grab, and cooperate with conveyor belts and chutes for transmission. There are disadvantages such as small medicine storage capacity, low medicine dispensing efficiency, inability to directly connect the medicine output to a liquid preparation machine, or low connection efficiency with a liquid preparation machine. Therefore, the automation process of hospital liquid preparation stops at partial achievements, and a large amount of manual intervention is still required for liquid preparation work, reducing the value and significance of automated work.

Detailed implementation manners

[0087] The present invention will be further described in detail below with reference to the accompanying drawings.

[0088] Embodiment 1:

[0089] As Figure 1 shown, an intelligent pharmacy medicine dispensing machine includes a tray 1, a vertical sorting mechanism 2 and an output mechanism 3.

[0090] As Figure 1 shown, the tray 1 is arranged in a honeycomb shape and has storage and sorting functions for storing and horizontally sorting single vial injection drugs. The tray 1 is distributed in a single row and multiple layers or multiple rows and multiple layers. At the same time, the tray 1 can also be symmetrically distributed in two groups and used in combination.

[0091] As Figure 1 shown, the vertical sorting mechanism 2 is located at the front end of the tray 1. When two trays 1 are used symmetrically, the vertical sorting mechanism 2 is located between the two trays 1 for vertically transporting and sorting the single vial injection drugs output from the tray 1.

[0092] As Figure 1 shown, the output mechanism 3 is located below the vertical sorting mechanism 2. The output mechanism 3 can be applied to two or more groups of trays 1 at the same time. That is to say, one output mechanism 3 can meet the transmission of single-dose injectable drugs output by multiple output vertical sorting mechanisms 2.

[0093] When dispensing injectable drugs, first place drugs of different varieties and quantities into the tray 1 according to requirements, and use the tray 1 to sort and transmit single-dose injectable drugs. Subsequently, use the vertical sorting mechanism 2 to transmit the drugs sent out by the tray 1 to the output mechanism 3, and ensure that each drug is assigned to a designated position in the output mechanism; finally, use the output mechanism 3 to perform the final transmission of the sorted drugs, which are manually transferred to the manual liquid preparation table and semi-automatic liquid preparation machine, or directly transmitted to the automatic liquid preparation machine.

[0094] As Figure 2 、 Figure 3 、 Figure 4 shown, the tray 1 includes a medicine cabin 11, an engine cabin 12 and a sorting component 13. Among them, the medicine cabin 11 is located at the front end of the tray 1, the engine cabin 12 is located at the rear end of the tray 1, and the sorting component 13 is located at the foremost end of the medicine cabin 11.

[0095] As Figure 2 、 Figure 3 、 Figure 4 shown, a plurality of flexible conveyor belts 111, a plurality of transverse partitions 112 and a plurality of longitudinal partitions 113 are arranged in the medicine cabin 11. Among them, the plurality of flexible conveyor belts 111 move from the rear to the front. The flexible conveyor belt 111 can be a chain or a synchronous belt. The plurality of flexible conveyor belts 111 are arranged side by side and move synchronously. The engine cabin 12 is internally provided with a driving source, which is a combination of a motor and a pulley. The pulley is respectively connected to the motor and the flexible conveyor belt 111 and is used to control the operation of the flexible conveyor belt 111.

[0096] As Figure 2 、 Figure 3 、 Figure 4 shown, the transverse partition 112 is arranged in an L shape, and the bottom surface is connected to the flexible conveyor belt 111. Among them, the vertical surfaces of the plurality of transverse partitions 112 are vertically fixed at intervals along the moving direction of the flexible conveyor belt 111. The longitudinal partition 113 is arranged in a straight plate shape, and the vertical surfaces of the longitudinal partition 113 are parallelly fixed at intervals along the moving direction of the flexible conveyor belt 111.

[0097] As Figure 2 、 Figure 3 、 Figure 4As shown, since the horizontal partition 112 and the vertical partition 113 are perpendicular to each other, a plurality of movable honeycomb-shaped medicine storage spaces are formed between the plurality of horizontal partitions 112 and the plurality of vertical partitions 113. Each medicine storage space stores a bottle of medicine. Therefore, when the plurality of flexible conveyor belts 111 work synchronously, the medicine storage spaces formed between the bottom surface and the vertical surface of the horizontal partition 112 and the vertical partition 113 work from back to front, and control the whole row of medicines to move forward, realizing the synchronous transportation of each row of single-category medicines.

[0098] As Figure 2 , Figure 3 , Figure 4 As shown, the sorting component 13 includes an arc track 131, an annular flexible traction belt 132 and a plurality of drive plates 133. The arc track 131 includes an arc bottom surface 134 and side vertical plates 135 located on both sides of the arc bottom surface 134. The starting end of the arc bottom surface 134 is connected to the bottom surface of the L-shaped horizontal partition 112, and the ending end of the arc bottom surface 134 is connected to the starting end of the vertical sorting mechanism 2. The distance between a pair of side vertical plates 135 is greater than the outer wall diameter of the medicine. At the same time, the starting end of the side vertical plate 135 is connected to the ending end of the outermost longitudinal partition, and the ending end of the side vertical plate 135 is connected to the starting end of the vertical sorting mechanism 2.

[0099] As Figure 2 , Figure 3 , Figure 4 As shown, the annular flexible traction belt 132 is arranged horizontally in a ring shape. A part of the annular flexible traction belt 132 is embedded in the arc bottom surface 134, and another part is embedded in the interval between the two adjacent L-shaped horizontal partitions 112 at the front end.

[0100] As Figure 2 , Figure 3 , Figure 4 As shown, the plurality of drive plates 133 are arranged vertically on the annular flexible traction belt 132, and are evenly distributed along the circumferential direction of the annular flexible traction belt 132, and have the same interval as the two adjacent vertical partitions 113, so as to stably slide in the arc track 131 and in the interval between the two adjacent L-shaped horizontal partitions 112 at the front end.

[0101] Therefore, when the tray 1 transports the medicine, the plurality of flexible conveyor belts 111 work synchronously and drive the horizontal partition 112 to move forward synchronously. At this time, the annular flexible traction belt 132 and the drive plates 133 are in a static state. Therefore, the frontmost horizontal partition 112 can pass through the gap between the drive plates 133 under the annular flexible traction belt 132.

[0102] When the required drugs are transported to the terminal position of the tray 1, the driving plate 133 is exactly located between a pair of lateral partitions 112 at the final end. An independent space for storing each bottle of drugs is formed between the adjacent driving plate 133 and the two lateral partitions 112 at the final end, and the drugs are located within this space.

[0103] At this time, the flexible conveyor belt 111 stops working. When the annular flexible traction belt 132 drives the driving plate 133 to work, the driving plate 133 pushes the drugs to move horizontally, causing the drugs to slide onto the arc bottom surface 134 of the arc track 131. Under the limiting action of the side vertical plate 135, the stable advancement of the drugs is ensured. When the drugs move to the terminal position of the arc track 131, the drugs automatically enter the starting end of the vertical sorting mechanism 2, thus realizing the horizontal sorting and transportation of single-category drugs.

[0104] As Figure 5 shown, the vertical sorting mechanism 2 includes an input sorting device 21, a vertical transmission device 22, and an output sorting device 23. The vertical transmission device 22 includes a platform and a plurality of short tubes, where the plurality of short tubes are arranged vertically and concentric in the vertical plane for connecting the input sorting devices 21 of the upper and lower layers.

[0105] As Figure 5 、 Figure 6 shown, the input sorting device 21 includes a receiving tube 211, a connecting tube 212, and a moving mechanism 213. The receiving tube 211 is a short tube with both ends permeable, capable of sliding on the surface of the platform of the vertical transmission device 22. And when sliding on the platform surface, because both ends of the receiving tube 211 are permeable, the drugs carried are sliding on the platform surface, realizing the temporary storage and transportation of the drugs. The upper end of the receiving tube 211 is provided with a flared shape that is circular or square to ensure that the drugs can accurately and stably fall into the receiving tube 211.

[0106] As Figure 5 、 Figure 6 shown, the connecting tube 212 is vertically fixed beside the receiving tube 211. And when two groups of trays 1 are used simultaneously, only one connecting tube 212 needs to be set, and the connecting tube 212 is located between a pair of receiving tubes 211. The connecting tube 212 can connect the short tubes of the upper and lower layers of the vertical transmission device 22 in the vertical direction for forming a vertically connected vertical transmission channel.

[0107] When the receiving tube 211 moves to below the terminal of the arc track 131 or below the terminal of the tray 1, the drugs will automatically fall into the receiving tube 211. When the receiving tube 211 slides in the reverse direction, the lower end of the receiving tube 211 will be docked with the upper end of the short tube of the lower-layer vertical transmission device 22. At this time, the drugs in the receiving tube 211 slide downward, and under the cooperative action of the lower-layer connecting tube 212, they fall into the vertical transmission channel and slide within the vertical transmission channel.

[0108] As Figure 5 、 Figure 6 shown, the moving mechanism 213 is a motor and a slide rail, wherein the storage tube 211 and the connecting tube 212 work synchronously with the slide rail in the moving mechanism 213 to control the storage tube 211 and the connecting tube 212 to slide horizontally and control the medicine to fall into the vertical transmission channel.

[0109] As Figure 5 、 Figure 6 、 Figure 7 shown, the output sorting device 23 includes an output tube 231, a first bottom valve 232 and a first sliding mechanism 233. The output tube 231 is a tube body with both ends transparent. The first bottom valve 232 is arranged in a plate shape at the lower end of the output tube 231. The first bottom valve 232 is rotatably or slidably connected to the lower end of the output tube 231 to control the opening and closing of the lower end of the output tube 231.

[0110] As Figure 5 、 Figure 6 、 Figure 7 shown, the first sliding mechanism 233 is composed of a motor and a slide rail. The slide rail can be a single slide rail. In this case, the motor is a single motor for controlling the linear movement of the storage tube 211. The slide rail can be two mutually perpendicular slide rails. In this case, the motor is a double motor and separately controls the sliding of each slide rail to control the movement of the output tube 231 in a two-dimensional plane.

[0111] As Figure 5 、 Figure 6 、 Figure 7 shown, a buffer plate 24 with a switching function is arranged between the short tube at the lowermost layer of the vertical transmission device 22 and the output tube 231, which can continue to receive the medicine output by the tray 1 during the movement of the output tube 231, and can significantly improve the transmission and sorting efficiency.

[0112] When the medicine slides down along the short tube on the lowermost layer of the vertical transmission device 22, the buffer plate 24 is in a closed state. At this time, the buffer plate 24 pre-buffers the medicine and reduces the falling speed of the medicine. The first sliding mechanism 233 is used to control the sliding of the conveying tube in the linear direction or the two-dimensional plane. When the upper end of the output tube 231 is docked with the lowermost end of the lowermost short tube, the buffer plate 24 is opened. At this time, the medicine slides into the output tube 231 and falls onto the first bottom valve 232 below the output tube 231.

[0113] Then, the first sliding mechanism 233 is used to control the sliding of the conveying tube in the linear direction or the two-dimensional plane. The lower end of the output tube 231 is docked with the output mechanism 3, and the first bottom valve 232 is opened, and the medicine falls into the output mechanism 3, thereby completing the sorting and transportation of the medicine in the vertical direction.

[0114] As Figure 1 、Figure 8 As shown, the output mechanism 3 includes a horizontal chain 31, a conveying plate 32, a pair of clamping rods 33, a number of rollers 34, a pair of incoming chains 35, a pair of outgoing chains 36, and a lifting plate 37.

[0115] As Figure 1 , Figure 8 shown, the horizontal chain 31 is horizontally arranged as a whole, and its length direction is perpendicular to the length direction of the tray 1, and is used to support the prescription box. The conveying plates 32 are arranged at intervals on the horizontal chain 31, and two adjacent conveying plates 32 are used to clamp the prescription box and control the horizontal transmission of the prescription box.

[0116] As Figure 8 shown, a pair of clamping rods 33 are horizontally distributed on both sides of the prescription box, and a number of rollers 34 are rotatably connected at intervals to the inner sides of the clamping rods 33 and are used to abut against the side walls of the prescription box to realize guiding and limiting during the transportation of the prescription box and ensure the stable transmission of the prescription box.

[0117] As Figure 8 shown, a pair of incoming chains 35 and a pair of outgoing chains 36 are respectively arranged above the starting end position and the ending end position of the horizontal chain 31 vertically, and the space between the pair of incoming chains 35 and the pair of outgoing chains 36 is used for the prescription box to pass through. The lifting plates 37 are arranged at intervals and horizontally on the incoming chains 35 and the outgoing chains 36 and are used to hook the upper edge position of the prescription box.

[0118] When the output mechanism 3 works, place the prescription box between the pair of incoming chains 35, so that the lifting plates 37 on the incoming chains 35 hook the upper edge position of the prescription box tightly, and then use the incoming chains 35 to gradually transport the prescription box to the horizontal chain 31 and let it fall between two adjacent conveying plates 32 on the horizontal chain 31. At this time, the prescription box disengages from the lifting plates 37 on the incoming chains 35.

[0119] With the operation of the horizontal chain 31, the latter of two adjacent conveying plates 32 leaves the arc section of the sprocket, and the distance between the two adjacent conveying plates 32 becomes smaller, thereby clamping the prescription box tightly, so that the prescription box can obtain a more accurate positioning in the traveling direction. The two conveying plates 32 push the prescription box to move, so that the prescription box enters between a pair of clamping rods 33. Restricted by the guide wheels of the clamping rods 33, the spatial position of the prescription box in the direction perpendicular to the traveling direction is also restricted. The combined action of the conveying plates 32 and the clamping rods 33 enables the prescription box to be accurately positioned and docked with the vertical transmission device 22 during the medicine output stage and smoothly receive the medicine from the vertical transmission device 22.

[0120] The horizontal chain 31 transports the prescription boxes through multiple output tube 231 workstations in sequence. When reaching a certain output tube 231 workstation, the horizontal chain 31 stops working. The output tube 231, driven by the first sliding mechanism 233, aligns with the predetermined space of the prescription box, and the first bottom valve 232 of the output tube 231 opens, and the medicine sliding out of the tube falls into the prescription box. Operating in this way successively, after completing the transmission task of the current output tube 231, the prescription box is transferred to the next output tube 231 workstation.

[0121] When the collection of the medicine is completed, the horizontal chain 31 continues to work and drives the prescription box to move synchronously. When reaching the termination end position, the horizontal chain 31 pauses. At this time, the upper edge of the prescription box is exactly at the position where it can be docked with the lifting plate 37 on the outgoing chain 36. Subsequently, the outgoing chain 36 works, and the prescription box is lifted by using the lifting plate 37 to realize the vertical transmission of the output end of the prescription box, and the medicine is transmitted to the designated position for receiving.

[0122] As Figure 1 、 Figure 9 As shown, a buffer mechanism 4 is provided between the vertical sorting mechanism 2 and the output mechanism 3. The buffer mechanism 4 includes a single-layer or multi-layer storage box 41 and a third bottom valve 42. A plurality of channels for storing single vial injection medicines are provided through the storage box 41, and the number, size and layout of the channels correspond to the prescription box. The third bottom valve 42 can be a rod-shaped, strip-shaped or plate-shaped rigid object, which is slidably or rotatably connected to the lower part of the storage box and is used to block the medicine and control the downward transmission of the medicine in the storage box 41 to the next level.

[0123] When the medicine is output at the termination end of the vertical sorting mechanism 2, the medicine will fall into the channels in the uppermost storage box 41 to realize the temporary storage of the medicine. When the lower storage box 41 is idle, the third bottom valve 42 of the upper layer opens, and the medicine is transmitted to the lower storage box 41 along the trend, realizing the sequential downward transmission of the whole batch of medicines together. Since each prescription is different, the trays 1, the vertical sorting mechanism 2 and the output mechanism 3 are sometimes idle and sometimes busy. The multi-layer storage box 41 can temporarily store the medicine to make full use of the idle time period. Transmitting the medicine from the storage box 41 to the prescription box in batches can greatly shorten the standby time of the prescription box. These two means enable the whole mechanism to obtain higher transmission and sorting efficiency.

[0124] Embodiment 2:

[0125] As Figure 10 、 Figure 11 As shown, an intelligent pharmacy medicine dispensing machine, which is different from that in Embodiment 1 in that: the output mechanism 3 includes a transmission chain 38. The transmission chain 38 is composed of inner links and outer links and is horizontally arranged as a whole. The inner link of the transmission chain 38 is a hollow tube with an open upper end to receive the medicine into it.

[0126] When the output mechanism 3 works, it controls the transfer chain 38 to move in the horizontal direction. When the inner link on the transfer chain 38 moves below the output tube 231, the transfer chain 38 stops working. At this time, the medicine that slides out of the output tube 231 can fall into the inner link, realizing the storage of the medicine. After the medicine collection is completed, the transfer chain 38 continues to work and drives the medicine to move synchronously. Subsequently, the transfer chain 38 transports the medicine to a designated position at the rear for receiving.

[0127] As Figure 10 , Figure 11 , Figure 12 shown, a buffer mechanism 4 is provided between the vertical sorting mechanism 2 and the output mechanism 3. The buffer mechanism 4 includes a storage tube group 43 composed of a single layer or multiple layers of multiple short tubes and a fourth bottom valve 44. The pipe diameters of the multiple short tubes correspond to the pipe diameter of the inner link of the transfer chain 38, and the intervals of the multiple short tubes correspond to the pitch of the transfer chain 38. The fourth bottom valve 44 can be a rod-shaped, strip-shaped or plate-shaped rigid object, which is slidably or rotatably connected below the storage tube group 43 for blocking the medicine and controlling the downward transfer of the medicine in the storage tube group 43 to the next level.

[0128] When the medicine is output at the termination end of the vertical sorting mechanism 2, the medicine will fall into the uppermost storage tube group 43, realizing the temporary storage of the medicine. When the lower storage tube group 43 is idle, the fourth bottom valve 44 on the upper layer opens, and the medicine is smoothly transferred into the lower storage tube group 43, realizing the sequential downward transfer of the whole batch of medicine together. Transferring the whole batch of medicine from the storage tube group 43 downward to the transfer chain 38 can significantly shorten the standby time of the transfer chain 38, thereby enabling the entire mechanism to obtain higher transfer and sorting efficiency.

[0129] Embodiment 3:

[0130] As Figure 13 , Figure 14 , Figure 15 shown, a difference between an intelligent pharmacy medicine dispensing machine and that of Embodiment 1 is that: a plurality of flexible conveyor belts 111 are located between two adjacent longitudinal partitions 113 and rotate independently. A plurality of transverse partitions 112 are vertically and fixedly connected to the flexible conveyor belts 111 at intervals, and a medicine storage space that can move with the flexible conveyor belts 111 is formed between the surfaces of the flexible conveyor belts 111, the transverse partitions 112 and the longitudinal partitions 113.

[0131] As Figure 13 , Figure 14 , Figure 15 shown, when the transverse partition 112 moves to the termination end position of the tray 1, the transverse partition 112 and the longitudinal partition 113 form an inclined downward sliding channel for the medicine to slide at the front end of the flexible conveyor belt 111, and at this time, the transverse partition 112 serves as the slide plate of the sliding channel.

[0132] Therefore, when transporting drugs, since the flexible conveyor belts 111 work independently, each flexible conveyor belt 111 can carry one type of drug. That is to say, the entire tray 1 can achieve synchronous and individual transportation requirements for multiple categories, meeting different prescription needs.

[0133] Therefore, when the flexible conveyor belt 111 works, it will drive the transverse partition 112 to move synchronously. When the transverse partition 112 moves to the end position of the tray 1, the root to the tip of the transverse partition 112 is inclined. At this time, the drugs can slide downward along the surface of the transverse partition 112, thus realizing the automatic sorting of drugs.

[0134] Such as Figure 15 、 Figure 16 shown, the receiving tube 211 is a short tube with a longitudinal notch on its side wall. The receiving tube 211 moves to the end of the downward-sliding channel formed by the transverse partition 112 and the longitudinal partition 113 at the front end of the flexible conveyor belt 111, and the notch of the receiving tube 211 is aligned with the downward-sliding channel, so that the drugs sliding down can be received.

[0135] Such as Figure 15 、 Figure 16 shown, the lower end of the receiving tube 211 is docked with the short tube of the vertical transmission device 22. The position and quantity of the short tubes of the vertical transmission device 22 are configured according to the position and quantity of the downward-sliding channels of the tray 1. The short tubes of the vertical transmission device 22 are used to connect the receiving tubes 211 and the connecting tubes 212 of the upper and lower layers, ensuring that the drugs can fall into the vertical transmission channel for transmission.

[0136] Embodiment 4:

[0137] Such as Figure 13 、 Figure 17 shown, an intelligent pharmacy drug dispensing machine, different from that in Embodiment 1 in that: the output sorting device 23 includes a flexible pipe 234, a second bottom valve 235 and a second sliding mechanism 236. The upper end of the flexible pipe 234 is flared and fixedly connected below the lower outlet positions of all the short tubes of the vertical transmission device 22, ensuring that the drugs falling from any short tube can smoothly enter the flexible pipe 234.

[0138] Such as Figure 17 shown, the second bottom valve 235 is plate-shaped and arranged at the lower end of the output pipe 231. The second bottom valve 235 is rotatably or slidably connected to the lower end of the flexible pipe 234 to control the opening and closing of the lower end of the flexible pipe 234. The second sliding mechanism 236 is composed of a motor and a slide rail. The slide rail is a single slide rail, and the motor is a single motor, used to control the linear movement of the lower end of the flexible pipe 234.

[0139] ​When the medicine slides down along the short pipe on the lowermost vertical transmission device 22, the medicine first passes through the buffer plate 24 with a switching function, and then enters the flexible pipe 234 and slides down along the flexible pipe 234.

[0140] Finally, the second sliding mechanism 236 is used to control the linear sliding of the flexible pipe 234 to adjust the position of the lower end of the flexible pipe 234, so as to deliver the medicine to the buffer mechanism 4 as required, completing the sorting and transportation of the medicine in the vertical direction.

[0141] Embodiment 5:

[0142] A medicine dispensing method for an intelligent pharmacy includes the following steps:

[0143] S1, medicine storage and horizontal sorting: Use a honeycomb-shaped tray 1 with storage and power sorting functions distributed in a single column and multiple layers or multiple columns and multiple layers, and cooperate with a fixed longitudinal partition 113 and a movable transverse partition 112 to form a movable honeycomb-shaped medicine storage space to complete the horizontal sorting output of individual medicine bottles;

[0144] S2, medicine vertical sorting: Use the receiving pipe 211 of the input sorting device 21 to receive the medicine from the tray 1 and place it into the vertical transmission device 22 for gravity transmission downward to reach the output sorting device 23. The output pipe 231 or the flexible pipe 234 of the output sorting device 23 carries the transmitted medicine and distributes it to the output mechanism 3;

[0145] S3, output of prescription boxes for sorted medicines: Use a horizontal chain 31 to support the prescription boxes, and use multiple vertically separated medicine storage spaces on the prescription boxes to give the medicines separate and specific storage spaces. And the prescription boxes pass through the output sorting devices 23 for multiple medicine vertical sortings in sequence to achieve the separate storage and sorting of each medicine;

[0146] S4, output of medicines by the chain after sorting: Use a transmission chain 38 to support the medicines, and use the upper open inner joints of the transmission chain 38 to receive the medicines into it. Each medicine is given a separate and specific storage space to achieve the separate storage and sorting of each medicine.

[0147] The specific embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
