Description

Technical Field

[0001] This invention relates to the field of intelligent dispensing equipment technology, and more specifically to a bidirectional motion multi-layer stacked medicine container and a dispensing device using the medicine container. Background Technology

[0002] With the rapid popularization of smart healthcare, automated pharmacies and self-service drug vending equipment, automated drug storage and dispensing structures have been widely used in hospital pharmacies at all levels, community self-service medicine cabinets, smart drug vending machines and other scenarios. This has greatly replaced the traditional manual drug dispensing and retrieval mode, effectively improving drug dispensing efficiency, reducing human operation errors, and meeting the public's demand for 24-hour uninterrupted drug supply.

[0003] Currently, most mainstream automated drug storage systems on the market adopt single-layer flat, fixed multi-layer inclined drug storage tanks, or unidirectional push-stacking drug storage structures. These systems can store conventional drugs and dispense them automatically, but they are large in size and have low space utilization, movement flexibility, dispensing accuracy, and adaptability, making it difficult to meet the needs of modern drug dispensing that require convenience, high precision, and high efficiency. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bidirectional motion multi-layer stacked medicine container and a dispensing device using the medicine container, so as to solve the problems that conventional medicine storage and automatic dispensing equipment in the background art are large in size, and have low space utilization, movement flexibility, dispensing accuracy and adaptability, making it difficult to meet the needs of modern medicine dispensing that is convenient, high-precision and high-efficiency.

[0005] This invention provides the following technical solution: a bidirectional, multi-layered, stacked drug container, comprising: The medicine box has a three-sided opening structure, and the inside of the medicine box is provided with a buckle strip, which divides the medicine box into two symmetrical double-row sliding cavities; Two mobile medicine compartments are slidably installed in two double-row sliding cavities, and each mobile medicine compartment has multiple equally spaced placement cavities. Driven tooth groove, the driven tooth groove is opened on the side wall of the movable medicine compartment near the end of the medicine box; A stacking mechanism is provided on both sides of the medicine box for stacking multiple medicine boxes.

[0006] As a further embodiment of the present invention, the side of the mobile medicine compartment is provided with a guide groove, and the inner walls of both sides of the medicine box are provided with guide protrusions that cooperate with the guide groove.

[0007] As a further embodiment of the present invention, the fastener is an inverted trapezoidal structure, and the fastener is inserted into the side of the mobile medicine compartment.

[0008] As a further embodiment of the present invention, the double-row sliding cavity is a cavity formed between the trapezoidal buckle and the guide protrusion to prevent the movable medicine container from falling off.

[0009] As a further embodiment of the present invention, the opening of the placement cavity of the mobile medicine container faces the double-row sliding cavity, thereby closing the opening of the placement cavity.

[0010] As a further embodiment of the present invention, the stacking mechanism includes: At least two stacking slots are provided, each located on the side of the medicine box away from the movable medicine compartment, and the two stacking slots are diagonally distributed. At least two stacked protrusions are provided on the same side of the medicine box and the double-row sliding cavity, and the positions of the two stacked protrusions correspond to the positions of the two stacked slots.

[0011] A two-way moving, multi-layered stacked medicine dispenser dispensing device, comprising two sets of dispensing equipment located on opposite sides of the medicine box, for driving two movable medicine containers respectively. The dispensing equipment includes: The mounting shell is installed in the mounting grooves opened on both sides of the medicine box; The external drive gear is installed inside the mounting housing and meshes with the driven gear slot. A geared motor is installed inside a mounting housing, and one end of the geared motor's output shaft is fixed to the external drive gear. The position sensor and controller are both mounted inside the housing.

[0012] As a further embodiment of the present invention, the side of the mounting shell is provided with a detection through hole and a driving through hole. The detection through hole is used to avoid the position sensor, and the driving through hole is used to avoid the driving external tooth.

[0013] As a further embodiment of the present invention, the controller includes a control module and a wireless communication module, and the control module, the wireless communication module, the position sensor and the geared motor are electrically connected.

[0014] The technical effects and advantages of this invention are as follows: 1. The two mobile medicine compartments of the present invention can slide independently and bidirectionally within their respective double-row sliding cavities and are driven by two independent dispensing devices. This allows the target medicine compartment to be operated independently while the other medicine compartment remains stationary when taking medicines from different locations or of different types. This achieves parallel operation capability, is convenient to use, significantly improves dispensing efficiency, and completely avoids mutual interference and confusion between different medicines during the dispensing process.

[0015] 2. The mobile medicine dispenser of the present invention can also be selected as a single-row mobile medicine dispenser. The single-row mobile medicine dispenser and the double-row mobile medicine dispenser are used in the same way to adapt to different medicine dispensing scenarios.

[0016] 3. The present invention achieves stable and neat stacking of multiple medicine boxes through diagonally distributed stacking slots and stacking protrusions, which not only greatly saves vertical storage space and is suitable for large-scale drug management, but also ensures that the medicine boxes in each layer will not shift during stacking.

[0017] 4. The trapezoidal buckle and guide protrusion of the present invention together form a double-row sliding cavity, which forms a mechanical lock on the movable medicine container, ensuring that it will not fall off during repeated pulling and pushing, and that the running trajectory is stable. At the same time, the opening of the placement cavity faces the inner wall of the double-row sliding cavity, and naturally forms a seal after the medicine container is pushed in, effectively preventing the medicine from accidentally spilling during storage and transportation, and also playing a certain role in dust prevention.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1-7 The present invention provides a bidirectional motion multi-layer stacked medicine container, including a medicine box 1, two movable medicine containers 2 and a stacking mechanism; Specifically, the medicine box 1 has a three-sided opening structure. Inside the medicine box 1, there is a buckle 4. The buckle 4 divides the medicine box 1 into two symmetrical double-row sliding cavities 3. The buckle 4 has an inverted trapezoidal structure and is inserted into the side of the movable medicine compartment 2. The side of the movable medicine compartment 2 has a guide groove 203. Both inner walls of the medicine box 1 have guide protrusions 101 that cooperate with the guide grooves 203. The double-row sliding cavity 3 is a trapezoidal structure. The buckle 4 and the guide protrusions 101 form an anti-fall-off chamber for the movable medicine compartment 2. It is used to install the movable medicine compartment 2 and allow the movable medicine compartment 2 to move freely in the double-row sliding cavity 3. This ensures that the movable medicine compartment 2 will not fall off when it slides out or is pushed in along the double-row sliding cavity 3, thus ensuring structural stability. Therefore, the two mobile medicine containers 2 are slidably installed in the two double-row sliding cavities 3 respectively. Each of the two mobile medicine containers 2 has multiple equally spaced placement cavities 201. The placement cavities 201 are used to hold medicines. The opening of the placement cavity 201 of the mobile medicine container 2 faces the double-row sliding cavity 3, forming a closure of the opening of the placement cavity 201, thereby blocking and sealing the medicine placed in the placement cavity 201. The two movable medicine containers 2 can slide independently in both directions within their corresponding double-row sliding cavities 3; this is a double-row movable medicine container 2 (e.g., Figure 4 As shown, when medication needs to be retrieved from different locations in the medicine box 1, the target mobile medicine compartment 2 can be pulled out separately at the corresponding distance without interfering with the position of the other mobile medicine compartment 2.

[0028] In addition, a driven toothed groove 202 is provided on the side wall of the mobile medicine container 2 near the medicine box 1. The driven toothed groove 202 cooperates with the dispensing equipment to realize the driving of the mobile medicine container 2. To solve the problem of stacking multiple medicine boxes 1 without them shifting: The stacking mechanism includes at least two stacking slots 5 and stacking protrusions 6, with the two stacking protrusions 6 corresponding to the positions of the two stacking slots 5; Specifically, two stacking slots 5 are respectively opened on the side of the medicine box 1 away from the movable medicine compartment 2, and the two stacking slots 5 are diagonally distributed; two stacking protrusions 6 are respectively set on the same side of the medicine box 1 and the double-row sliding cavity 3. Therefore, when multiple medicine boxes 1 are stacked, they are respectively inserted into two stacking slots 5 by two stacking protrusions 6, thereby realizing the stacking and positioning of multiple medicine boxes 1.

[0029] Furthermore, a bidirectional, multi-layered, stacked drug dispensing device; It should be noted that there are two sets of dispensing equipment, which are respectively located on both sides of the medicine box 1 and are used to drive two mobile medicine chambers 2 respectively. The dispensing equipment includes a mounting shell 8, a drive gear 11, a reduction motor 13, a position sensor 10 and a controller 14. Specifically, the mounting shell 8 is installed in the mounting grooves 7 opened on both sides of the inner wall of the medicine box 1; The drive gear 11, the geared motor 13, the position sensor 10 and the controller 14 are all installed in the mounting housing 8. The drive gear 11 meshes with the driven gear groove 202. One end of the output shaft of the geared motor 13 is fixed to the drive gear 11. The geared motor 13 drives the drive gear 11 to rotate, so that the drive gear 11 drives the mobile medicine container 2 to move along the double-row sliding cavity 3 through the driven gear groove 202. It should be noted that the side of the mounting housing 8 is provided with a detection through hole 801 and a drive through hole 802. The detection through hole 801 is used to avoid the position sensor 10, and the drive through hole 802 is used to avoid the drive external tooth 11.

[0030] The controller 14 contains a control module and a wireless communication module, and the control module, wireless communication module, position sensor 10, and geared motor 13 are electrically connected. It should be noted that the control module (STM32F103 microcontroller), the wireless communication module (whose working principle is based on signal encoding modulation and demodulation, and completes electromagnetic wave conversion through radio frequency transceiver and antenna, supporting multiple communication standards such as Bluetooth, WiFi, LoRa, and NB-IoT), the position sensor 10, and the geared motor 13 are all existing technologies. For example, the position sensor 10 can be an optical linear position sensor (such as a grating ruler) based on optical interference or grating principles. The scale grating and the indicator grating are respectively installed on the mobile medicine container 2 and the mounting shell 8. When the scale grating and the indicator grating move relative to each other, they will generate alternating bright and dark moiré fringes. The number and direction of the fringe movement are detected by photoelectric elements, thereby outputting a digital pulse signal (incremental) or an absolute position code (absolute), realizing accurate measurement of the movement position of the mobile medicine container 2. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0031] Therefore, remote operation and control can be achieved through a host computer and a wireless communication module. The control module controls the start and stop of the reduction motor 13, while the position sensor 10 detects the position of the mobile medicine container 2 in real time and determines whether it has reached the designated position (the dispensing system process is as follows). Figure 7 (As shown).

[0032] When the position sensor 10 detects that the mobile medicine container 2 has reached the designated dispensing position, it will immediately send a position signal to the control module. The control module will then control the reduction motor 13 to stop running, so that the mobile medicine container 2 stops precisely at the corresponding position of the dispensing outlet, completing a single medicine delivery action. If different specifications of medicine need to be changed, the control module will control the geared motor 13 to start according to the instructions sent by the host computer, and drive the target mobile medicine bin 2 to move to the designated position; at the same time, the other mobile medicine bin 2 will remain stationary in its original position and will not interfere with the current medicine dispensing process. The design of the two sets of equipment operating independently not only improves the medicine dispensing efficiency, but also avoids confusion when different medicines are dispensed.

[0033] As a further implementation method: the mobile medicine storage unit 2 is a single-row type (e.g., Figure 6 As shown), a single-row sliding cavity 301 is formed between the two guide protrusions 101 of the medicine box 1 to limit the single-row movable medicine container 2, and only one dispensing device is needed; Specifically, the reduction motor 13 of the dispensing equipment drives the single-row mobile medicine bin 2 to move along the single-row sliding cavity 301 formed by two guide protrusions 101 to realize the dispensing action. The single-row mobile medicine bin 2 and the double-row mobile medicine bin 2 can be adapted to different dispensing scenarios.

[0034] The present invention is used in the following steps: S1: When loading medicine, medicine box 1 is placed facing upwards, that is, the placement cavity 201 of the mobile medicine compartment 2 faces upwards, and then the medicine is placed into the placement cavity 201 layer by layer; S2: When dispensing medicine, the medicine box 1 is inverted, that is, the placement cavity 201 of the mobile medicine container 2 faces downward. Then, remote operation and control are realized through the host computer and the wireless communication module. The control module controls the start and stop of the reduction motor 13. At the same time, the position sensor 10 detects the position of the mobile medicine container 2 in real time and drives the target mobile medicine container 2 to move to the designated position.

[0035] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change. The electronic components and modules used in this invention can all be commonly used parts on the market that can achieve the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs; The accompanying drawings of the embodiments disclosed in this invention only involve structures relevant to the embodiments disclosed in this invention. Other structures can be referred to with common designs. Unless otherwise specified, the same embodiment and different embodiments of this invention can be combined with each other.
