Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece dispensing technology, specifically to an automatic dispensing and weighing trolley for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) dispensing processes rely on manual identification of medicine cabinet locations, manual weighing, and dispensing. This is not only inefficient but also prone to inaccurate weights due to human error. Furthermore, pharmacists must frequently move between cabinets to retrieve medications, resulting in high labor intensity. In addition, manual recording and management of prescription information are susceptible to oversights, and the lack of standardized operating procedures and automated auxiliary equipment makes it difficult to meet the demands of large-scale, precise TCM dispensing. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing an automatic hopper and weighing trolley for Chinese herbal medicine slices, in order to overcome the defects of the prior art, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides an automatic hopper and weighing trolley for Chinese herbal medicine slices, including an AGV trolley. The AGV trolley is equipped with an outer box, and the outer box is equipped with a loose slice storage box. The upper side of the outer box is respectively provided with a window and several sub-baskets. A weighing pan structure is hinged and rotatably arranged at the window. The outer box is equipped with a flip drive component for driving the hinged rotation of the weighing pan structure.

[0006] When the tilting drive component drives the weighing pan structure to rotate hingedly, the weighing pan structure can rotate from a horizontal weighing state toward the outer box to an inclined state, so as to pour the material on the weighing pan structure into the bulk material storage box.

[0007] Preferably, the weighing pan structure includes a support plate, a pan body is disposed above the support plate, and a weighing sensor is disposed between the pan body and the support plate.

[0008] Preferably, the flipping drive assembly includes a hinge shaft, one side of the support plate is hinged to the outer housing via the hinge shaft, a belt linear module is provided in the outer housing, the lifting output end of the belt linear module is provided with a first hinge seat, a second hinge seat is provided on the support plate, and a connecting rod connects the first hinge seat and the second hinge seat to each other.

[0009] Preferably, the outer casing is provided with a bottom box for neatly storing the distributed baskets.

[0010] Preferably, a bracket is provided on the outer casing, the human-machine interface is set on the bracket, and a camera is also set on the bracket.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-6As shown, this utility model provides an automatic hopper-finding and weighing trolley for Chinese herbal medicine slices, including an AGV trolley 1 and a human-machine interface 7. The AGV trolley 1 serves as a mobile carrier, responsible for moving the entire device to the target hopper location according to system instructions. An outer casing 2 is mounted on the AGV trolley 1. The outer casing 2 contains a loose slice storage box 3 for storing Chinese herbal medicine slices that do not need to be separated. A window 202 is opened on one side of the upper part of the outer casing 2, serving as a channel for the weighing pan structure 4 to flip and pour materials, facilitating the introduction of materials into the loose slice storage box 3. Several separation baskets 5 are arranged on the other side of the upper part of the outer casing 2. The system includes a bottom box 501 for neatly storing the dispensing basket 5, allowing manual dispensing of medicines according to the principle of equal reduction; a weighing pan structure 4 is hinged and mounted at the window 202 to receive manually grasped Chinese herbal medicine pieces and facilitate weighing operations; a flipping drive assembly 12 is also provided on the outer casing 2, which drives the weighing pan structure 4 to rotate around the hinge axis, causing the weighing pan to flip from a horizontal weighing state to an inclined pouring state, completing the material transfer; the human-machine interface 7 is used to display prescription information, such as medicine name, weight, and dosage, facilitating viewing and related operations for operators.

[0030] When the flipping drive assembly 12 drives the weighing pan structure 4 to rotate hingedly, the weighing pan structure 4 can rotate from a horizontal weighing state toward the inner side of the outer box 2 to an inclined state, so as to pour the material on the weighing pan structure 4 into the bulk material storage box 3.

[0031] See instruction manual attached Figure 5 and Figure 6 As shown, the weighing pan structure 4 consists of a support plate 403, a pan body 401, and a weighing sensor 402. The support plate 403 serves as the basic load-bearing component, providing mounting support for the pan body 401 and the weighing sensor 402 above. The pan body 401 is directly used to place the manually grasped Chinese herbal medicine pieces. The weighing sensor 402 between the pan body 401 and the support plate 403 is responsible for detecting the weight of the Chinese herbal medicine pieces in the pan and feeding the weight data back to the human-machine interface 7 to determine whether the total weight of the single herb required by the prescription has been met, with an allowable error of ±2g.

[0032] The rotating drive assembly 12 that works in conjunction with it includes a hinge shaft 1205, a belt linear module 1201, a first hinge seat 1202, a connecting rod 1203, and a second hinge seat 1204. One side of the support plate 403 is hinged to the inside of the outer housing 2 through the hinge shaft 1205 to form a rotatable fulcrum. The belt linear module 1201 inside the outer housing 2 serves as a power source, and its lifting output end is connected to the first hinge seat 1202, which can drive the first hinge seat 1202 to move up and down. The second hinge seat 1204 on the support plate 403 is connected to the first hinge seat 1202 through the connecting rod 1203 to form a linkage structure. When materials need to be transferred, the belt linear module 1201 drives the first hinge seat 1202 to descend, and drives the second hinge seat 1204 through the connecting rod 1203, causing the support plate 403 to rotate around the hinge shaft 1205, thereby driving the entire weighing pan structure 4 to flip from the horizontal weighing state to the tilted state, and pouring the Chinese herbal medicine pieces in the pan into the loose pieces storage box 3 in the outer box 2 through the window 202.

[0033] A bracket 8 is installed on the outer casing 2, and a human-machine interface 7 is installed on the bracket 8. A camera 6 is also installed on the bracket 8. An access port is provided on the outer casing 2, and two cabinet doors 201 are provided at the access port.

[0034] The AGV also includes two first dot positioning lights 10 and two second dot positioning lights 11 distributed vertically. A bidirectional slide assembly 9 is provided between the first dot positioning lights 10 and the second dot positioning lights 11 for synchronously moving them in opposite directions. The bidirectional slide assembly 9 includes a slide bracket 901 mounted on the AGV 1. A pulley 904 is mounted on the top of the slide bracket 901, and a stepper motor 902 for driving the winding and unwinding of a synchronous belt 903 is mounted on the bottom of the slide bracket 901. A first slide 1001 and a second slide 1101 are slidably mounted on the slide bracket 901 in the vertical direction. One end of the synchronous belt 903 changes direction, passes around the pulley 904, and is fixedly connected to the second slide 1101. The first slide 1001 is mounted on the synchronous belt 903 opposite to the second slide 1101. A protective shell 906 for protecting the pulley 904 is bolted to the top of the slide bracket 901. Through the above-mentioned specific structural design, when the stepper motor 902 drives the synchronous belt 903 to operate, since the first slide 1001 and the second slide 1101 are respectively fixed on the opposite sections of the synchronous belt 903, the two will move synchronously in opposite directions along the slide bracket 901. That is, when the first slide moves up, the second slide moves down, and vice versa. This drives the first dot positioning light 10 and the second dot positioning light 11 to accurately adjust their positions, thereby achieving rapid positioning of medicine hoppers at different heights.

[0035] Working principle:

[0036] In use, the bidirectional slide assembly 9, driven by the stepper motor 902, moves the first dot positioning light 10 and the second dot positioning light 11 in opposite directions through the cooperation of the synchronous belt 903 and the pulley 904. This achieves precise positioning of the target location and assists the AGV trolley 1 in automatically finding the medicine drawer. The two first dot positioning lights 10, illuminating the left and right sides respectively, are responsible for positioning the medicine drawers in the upper part of the medicine cabinet, while the two second dot positioning lights 11, illuminating the left and right sides respectively, are responsible for positioning the medicine drawers in the lower part of the medicine cabinet. When the first dot positioning light 10 or the second dot positioning light 11 of the bidirectional slide assembly 9 is aligned with the center of the medicine drawer corresponding to the prescription, the dot positioning light automatically illuminates, visually reminding the pharmacist to open the corresponding medicine drawer, thus completing the automatic medicine drawer finding process.

[0037] The weighing pan structure 4 has a pan body 401 for placing Chinese herbal medicine slices. The weighing sensor 402 between the pan body 401 and the support plate 403 can detect the weight of the slices and feed the data back to the system.

[0038] When the weighed material needs to be poured into the bulk material storage box 3, the flipping drive assembly 12 starts to work. The belt linear module 1201 drives the first hinge seat 1202 to rise and fall. Through the linkage of the connecting rod 1203 and the second hinge seat 1204, the support plate 403 rotates around the hinge shaft 1205, causing the weighing pan structure 4 to flip from the horizontal weighing state to the tilted state, thereby pouring the material into the bulk material storage box 3 inside the outer box 2 through the window 202.

[0039] If dispensing is required, the medicines are manually placed into the dispensing basket 5 according to the principle of equal and decreasing quantity. The dispensing basket 5 is placed in the bottom box 501 on the upper surface of the outer box 2, which can make the dispensing basket 5 neatly stored and facilitate the dispensing of materials.

[0040] Operators can input operating commands and monitor equipment operation status through the human-machine interface 7 on the bracket 8. Simultaneously, the camera 6 can capture and monitor relevant operating processes or material conditions, ensuring the accuracy and reliability of the work.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
