Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb processing technology, and in particular to an equal-volume dispensing device for the production of Chinese medicinal herb processing. Background Technology

[0002] Traditional Chinese medicinal herbs (TCM) processed pieces are TCM herbs that have undergone processing according to TCM theories and methods, and can be directly used in TCM clinical practice. TCM processed pieces include some sliced ​​herbs processed at their place of origin, raw herbs, and processed pieces. TCM processed pieces are important raw materials for TCM preparations. Their production process involves multiple steps such as cleaning, cutting, and processing, ultimately producing standardized processed pieces. For ease of storage, transportation, and subsequent formulation, TCM processed pieces need to be packaged by fixed weight. Traditional packaging methods rely heavily on manual weighing and filling, which is inefficient and susceptible to human error, leading to inconsistent packaging accuracy and failing to meet the large-scale requirements of modern TCM production.

[0003] Currently, there are some automated dispensing devices on the market, such as vibrating feeder dispensing machines or screw conveyor dispensing equipment. However, these devices generally have the following problems: 1) Dispensing accuracy is greatly affected by the flowability of materials, especially for sliced ​​or unevenly sized Chinese medicinal materials, which are prone to jamming or accumulation; 2) It is difficult to achieve independent control of each dispensing unit when dispensing at multiple stations, resulting in low dispensing efficiency; 3) There is a lack of dynamic weight feedback mechanism, which makes it impossible to adjust the dispensing speed in real time, affecting the consistency of dispensing.

Detailed Implementation

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0026] In one embodiment, such as Figures 1-3 As shown, an equal-volume dispensing device for the production of Chinese medicinal herbs includes a preparation cylinder 100, a control panel 400, and multiple dispensing guide mechanisms 200 circumferentially distributed on the outer side of the preparation cylinder 100. Each dispensing guide mechanism 200 is provided with a support portion 300, which serves as a support to support the dispensing guide mechanism 200 and the preparation cylinder 100. The bottom of the support portion 300 has a support platform for carrying dispensing bottles, and the support platform has a weighing pan 310 for detecting the weight borne by the surface of the support platform. Multiple dispensing ports 120 are opened on the side wall of the preparation cylinder 100 near the bottom. The dispensing guide mechanism 200 includes a conveying assembly 600 and a dropping cylinder assembly 700. One end of the conveying assembly 600 is fixedly connected to the circumferential side wall of the preparation cylinder 100, and the conveying assembly 600 passes through one of the... The dispensing port 120 is connected to the interior of the preparation cylinder 100. The dispensing cylinder assembly 700 is located at the end of the conveying assembly 600 away from the preparation cylinder 100. The dispensing cylinder assembly 700 includes a dispensing cylinder 710 and a cover plate unit located at the bottom opening of the dispensing cylinder 710. The end of the conveying assembly 600 away from the preparation cylinder 100 extends into the dispensing cylinder 710 and is used to convey the Chinese medicinal herbs in the preparation cylinder 100 into the dispensing cylinder 710. The lower port of the dispensing cylinder 710 faces the dispensing bottle weighing pan 310. The cover plate unit can be rotated to open and close and senses the weight of the Chinese medicinal herbs on its surface. The control panel 400 is located on the side of the preparation cylinder 100. The conveying assembly 600, the cover plate unit, and the dispensing bottle weighing pan 310 in each dispensing guide mechanism 200 are all connected to the control panel 400 via data communication.

[0027] In this embodiment of the invention, the target weight of the cover plate unit in each dispensing and guiding mechanism 200 is set via the control panel 400. When the cover plate unit senses that the weight of the Chinese medicinal herbs inside the preparation cylinder 100 has reached the target weight, the cover plate unit opens by rotation. Before dispensing, the Chinese medicinal herbs to be dispensed are placed in the preparation cylinder 100, and dispensing bottles are placed on the dispensing bottle weighing pan 310. The control panel 400 sets the target weight of the cover plate unit separately according to the size of the dispensing bottle on each dispensing bottle weighing pan 310. The control panel 400 also sets the target weight of the cover plate unit separately according to the target weight. The weight control corresponds to the conveying speed of the feeding assembly 600 for transporting Chinese medicinal herbs. During the packaging process, the Chinese medicinal herbs in the preparation cylinder 100 enter the corresponding feeding assembly 600 near the end of the preparation cylinder 100 through the dispensing port 120. The feeding assembly 600 operates under the activation of the control panel 400, conveying the Chinese medicinal herbs into the discharge cylinder 710. The Chinese medicinal herbs in the discharge cylinder 710 fall onto the cover unit, which senses the weight of the Chinese medicinal herbs. When the weight of the Chinese medicinal herbs reaches the set target weight, the feeding assembly stops the flow. The control panel 400 receives the signal and controls the cover unit to rotate and open, and the conveying assembly 600 to stop conveying the Chinese medicinal herbs. The Chinese medicinal herbs fall from the bottom of the discharge cylinder 710 and completely into the dispensing bottles on the dispensing bottle weighing pan 310. The cover unit rotates and seals the discharge port of the discharge cylinder 710. The dispensing bottle weighing pan 310 can sense the weight change on the surface of the support platform. When the weight change of the Chinese medicinal herbs in the dispensing bottle is the same as the target weight, it indicates that the dispensing bottle has reached the dispensing weight. After dispensing, a robotic arm or other equipment is used to transfer the dispensing bottle to the next container. The dispensing bottles filled with Chinese medicinal herbs are removed from the carrier platform, and the empty dispensing bottles are placed on the carrier platform. The entire dispensing process is simple and highly efficient due to its automation. The control panel 400 also controls the speed at which the corresponding conveyor assembly 600 transports the Chinese medicinal herbs according to the target weight. When the target weight is large, the conveyor assembly 600 increases the speed of transporting the Chinese medicinal herbs, and when the target weight is small, the conveyor assembly 600 decreases the speed of transporting the Chinese medicinal herbs. This allows for control over the time of each dispensing operation, facilitating the use of a robotic arm to uniformly replace the dispensing bottles and further improving dispensing efficiency.

[0028] The control panel 400 includes a signal receiving module, a weighing setting module, a central processing unit, and an output execution module. The signal receiving module receives electrical signals transmitted after receiving the weight borne by the dispensing bottle weighing pan 310 and the cover unit. The weighing setting module sets the target weight borne by the cover unit. The central processing unit executes an algorithm and outputs adjustment commands based on the electrical signals received by the signal receiving module. The output execution module sends action commands to the conveyor assembly 600 and the cover unit.

[0029] In one embodiment, such as Figures 1-4As shown, the conveying assembly 600 includes a conveying channel 610, a conveying drive unit 630, and two conveying units 620. One end of the conveying channel 610 is fixedly connected to the outer wall of the material preparation cylinder 100 and communicates with one of the distributing ports 120. The other end of the conveying channel 610 extends into the material discharge cylinder 710. The two conveying units 620 are arranged opposite each other inside the conveying channel 610 along its length. The conveying drive unit 630 is located at one end of the conveying channel 610 and connected to the two conveying units 620. The conveying drive unit 630 is also electrically connected to the control panel 400, which can control the working state of the conveying drive unit 630. In this embodiment of the invention, the conveying drive unit... Under the control of the control panel 400, 630 drives two conveying units 620 to work. The two conveying units 620 convey the Chinese medicinal materials at the end of the material conveying channel 610 connected to the preparation cylinder 100 at a uniform speed to the discharge cylinder 710 through the gap between the two. Since the conveying units 620 convey the Chinese medicinal materials at a uniform speed, the weight of the Chinese medicinal materials in the discharge cylinder 710 per unit time is clear. Therefore, the dispensing time can be clearly defined, which facilitates the work of the robot arm to pick up and put down the dispensing bottles, and makes the whole dispensing work orderly. Among them, the outer wall of the discharge cylinder 710 is provided with a clearance opening 720 near the top. The end of the material conveying channel 610 away from the preparation cylinder 100 extends into the discharge cylinder 710 through the clearance opening 720.

[0030] In one embodiment, such as Figures 1-5As shown, the conveying unit 620 includes two pulley shafts 621 and two pulley sections 623. The two pulley shafts 621 are rotatably disposed inside the material conveying channel 610 and are respectively located at both ends. The two pulley sections 623 are respectively disposed on the pulley shafts 621. A blocking belt 622 surrounds the outer side of the two pulley sections 623. The outer surface of the blocking belt 622 has a plurality of equally spaced deflector sections 624. The plurality of deflector sections 624 in the two conveying units 620 correspond one-to-one and are located in the two conveying units 620. The ends of a pair of opposing paddle plates 624 between two sets of 20 abut each other; a conveying cavity 625 for accommodating Chinese medicinal herbs is formed between two adjacent sets of paddle plates 624; one of the pulley shafts 621 in each conveying unit 620 is connected to the conveying drive unit 630; in this embodiment of the invention, the conveying drive unit 630 drives the conveying channels 610 in the two conveying units 620 to rotate synchronously in opposite directions, and the conveying channels 610 drive the blocking belt 622 to circulate between the two pulleys via the pulley portion 623. The two paddle plates 624 in the same group move towards the discharge cylinder 710 when they are between the two pulley shafts 621. The Chinese medicinal materials in the preparation cylinder 100 are gathered at the front end of the conveying channel 610 through the dispensing port 120. The paddle plate 624 moves with the blocking belt 622. When the paddle plate 624 moves to the front end of the conveying channel 610, it gradually abuts against the other paddle plate 624 in the same group. The paddle plate 624 will also be in the middle of the front end of the conveying channel 610. The medicinal herbs are pushed towards the discharge cylinder 710. The medicinal herbs move within the conveying cavity 625 formed by two adjacent sets of pusher plates 624. The two pusher plates 624 in the same set separate at the ends of the conveying channel 610 that extend into the discharge cylinder 710, and push the medicinal herbs into the discharge cylinder 710 to realize the conveying of medicinal herbs. The amount of medicinal herbs in each conveying cavity 625 is equal. Therefore, the conveying amount of medicinal herbs per unit time can be controlled by controlling the rotation speed of the pulley shaft 621.

[0031] In one embodiment, such as Figures 1-5As shown, in each conveying unit 620, the top of a pulley shaft 621 extends to the upper surface of the conveying channel 610 and is provided with a worm gear portion 626. The conveying drive unit 630 includes a main shaft portion 631, a conveying motor 632, and two worm gear portions 633. The main shaft portion 631 is rotatably mounted on the upper surface of the conveying channel 610, and the conveying motor 632 is connected to one end of the main shaft portion 631. The two worm gear portions 633 are both provided on the main shaft portion 631 and are respectively connected to the two worm gear portions 626. The two worm gears 633 mesh with each other, and their rotation directions are opposite. In this embodiment of the invention, the feeding motor 632 is controlled by the control panel 400 to drive the main shaft 631 to rotate. The rotating main shaft 631 causes the pulley shaft 621 to rotate through the cooperation of the worm gears 633 and the main shaft 631. Since the two worm gears 633 rotate in opposite directions, the two pulley shafts 621 rotate synchronously in opposite directions, so that the two paddle plates 624 in the same group paddle the Chinese medicinal materials slices towards the feed cylinder 710.

[0032] In one embodiment, such as Figures 2-5 As shown, the cover plate unit includes a weighing cover plate part 730 and an electrically controlled cylinder part 740. The weighing cover plate part 730 is located at the discharge port of the discharge cylinder 710. A rotating support arm 712 is fixed to the bottom surface of the weighing cover plate part 730. One end of the rotating support arm 712 away from the weighing cover plate part 730 is hinged to a hinge seat part 711 located on the outer wall of the discharge cylinder 710. The electrically controlled cylinder part 740 is located on the support frame part 300, and one end of it is hinged to a push-pull slide 750. The push-pull slide 750 The slide rail 731 located on the lower end face of the weighing cover plate 730 is slidably engaged with it. In this embodiment of the invention, the electrically controlled cylinder 740 extends and retracts under the control of the control panel 400. Through its extension and retraction, it acts on the push-pull slide 750 to push and pull the weighing cover plate 730. The weighing cover plate 730 rotates around the hinge seat 711 to open and close the discharge port. A weighing sensor array is embedded inside the weighing cover plate 730 to accurately sense the weight of the Chinese medicinal materials in the discharge cylinder 710.

[0033] In one embodiment, such as Figures 2-5 As shown, the discharge port at the bottom of the discharge cylinder 710 is angled, and the weighing cover plate 730 has a buffer pad 760 on the end face facing the discharge port. In this embodiment of the invention, the buffer pad 760 can buffer the impact of the falling Chinese medicinal herbs, and the angled discharge port can play a guiding role. After the discharge port is opened, the weighing cover plate 730 can guide the Chinese medicinal herbs to fall into the dispensing bottle and ensure that the Chinese medicinal herbs in the discharge cylinder 710 are completely discharged. The gravity sensed by the weighing sensor array on the weighing cover plate 730 is perpendicular to the weighing cover plate 730. The actual weight of the Chinese medicinal herbs is vertically downward. According to the tilt angle of the discharge port, the two have a corresponding conversion relationship. ⊥ =W*cosθ,W ⊥The apparent weight detected by the sensor is the pressure component perpendicular to the weighing cover plate 730, θ is the tilt angle of the weighing cover plate 730, and W is the actual weight of the Chinese medicinal herb slices.

[0034] In one embodiment, such as Figure 1 and Figure 6 As shown, a conical discharge assembly 500 is provided inside the material preparation cylinder 100. The conical discharge assembly 500 includes a discharge shaft 510, a feeding cone 520, a discharge motor 530, and a lower turntable 540. The lower turntable 540 is rotatably mounted on the bottom wall inside the material preparation cylinder 100. The bottom edge of the distributing port 120 is flush with the upper surface of the lower turntable 540. The feeding cone 520 is mounted on the lower turntable 540, and its diameter gradually increases from top to bottom. The discharge shaft 510 is located at the center of the material preparation cylinder 100, and its top is rotatably connected to a cylinder mouth support 110 located at the top opening of the material preparation cylinder 100. The bottom is fixedly connected to the feeding cone 520, and the output end of the discharge motor 530 is connected to the top of the discharge shaft 510. In this embodiment of the invention, the feeding cone 520 can guide the Chinese medicinal materials in the preparation cylinder 100 to the periphery of the preparation cylinder 100, so that the Chinese medicinal materials can enter the conveying assembly 600 through the distributing port 120. The discharge motor 530 can act on the feeding cone 520 and the lower turntable 540 through the discharge shaft 510 to make them rotate. The rotating feeding cone 520 and the lower turntable 540 can move the Chinese medicinal materials in the corner of the preparation cylinder 100 to the distributing port 120, so as to facilitate complete discharge.

[0035] The above embodiment provides an equal-volume dispensing device for the production of prepared slices of traditional Chinese medicine, the working principle of which is as follows:

[0036] 1. System initialization and parameter settings

[0037] Preparation stage: Pour the Chinese medicinal herbs to be packaged into the preparation cylinder 100, and place empty packaging bottles on the support platform of each packaging guide mechanism 200.

[0038] Target weight setting: Through the weighing setting module of the control panel 400, set the target weight (i.e. the amount of a single serving of herbal slices) for each cover unit according to the capacity of the dispensing bottle.

[0039] Material conveying speed matching: The control panel 400 automatically adjusts the conveying speed of the corresponding conveyor component 600 according to the target weight (increase the speed when the target weight is large, and decrease it when the target weight is small) to ensure that the dispensing time of each dispensing guide mechanism 200 is synchronized, which facilitates the robot to replace the dispensing bottles in a unified manner.

[0040] 2. Medicinal slices conveying and dynamic weighing

[0041] Cone discharge: The discharge motor 530 drives the discharge shaft 510 to rotate the feeding cone 520 and the lower turntable 540, which pushes the slices in the preparation cylinder 100 evenly to the distribution port 120 on the periphery.

[0042] Feeding: The feeding motor 632 drives two sets of feeding units 620 to rotate synchronously in opposite directions through the main shaft 631 and the worm gear 633. The feeding plate 624 forms a conveying cavity 625, which feeds the medicinal slices from the dispensing port 120 into the dropping cylinder 710. The uniformly rotating feeding plate 624 ensures that the weight of the medicinal slices conveyed per unit time is constant (e.g., conveying 10 grams per second), which is convenient for time control.

[0043] Weighing on the cover: After the medicinal slices fall into the feeding cylinder 710, they accumulate on the weighing cover 730. The built-in weighing sensor array detects the weight in real time and feeds the data back to the control panel 400.

[0044] 3. Precise dispensing and material feeding control

[0045] Weight target determination: When the cover unit detects that the weight of the medicinal slices has reached the target value, the control panel 400 issues a command:

[0046] Stop feeding: Pedal motor 632 pauses, terminating the feeding of medicinal slices.

[0047] Opening the lid: The electrically controlled cylinder 740 pushes the slide block 750, causing the weighing lid 730 to rotate around the hinge 711 and open, allowing the medicinal slices to slide into the dispensing bottle through the angled discharge port. The buffer pad 760 reduces impact and ensures that the medicinal slices are completely discharged.

[0048] Dispensing verification: The dispensing bottle weighing pan 310 monitors the weight of the medicinal slices inside the bottle in real time. If it matches the target weight, the dispensing is complete; if the deviation is too large, the system will issue an alarm.

[0049] 4. Cyclic Operations and Automated Management

[0050] Reset and Next Round of Packaging: The cover unit closes, the conveyor assembly 600 restarts, and the next batch of conveying begins. The robotic arm removes full bottles and replaces empty bottles, and the platform weight is reset to zero before starting a new round of packaging.

[0051] Abnormal Handling: If the dispensing bottle weighing pan 310 detects an abnormal weight (such as the bottle not being placed upright), the control panel 400 will pause the corresponding workstation and prompt for manual intervention.
