Description

Technical Field

[0001] This utility model relates to a dispensing device, specifically, to an intelligent dispensing device for chemical reagent powder packets. Background Technology

[0002] In automated production processes, it is often necessary to handle and place various objects. For example, Patent Document 1 provides a vacuum pickup technology that utilizes the principle of negative pressure to grasp and transport objects by generating a vacuum, without direct contact with the object's surface, thus preventing damage. Vacuum pickup technology is widely used in fields such as electronic assembly, food processing, pharmaceutical packaging, and logistics handling. It can handle objects of various shapes and sizes, including fragile and sensitive materials.

[0003] In industries such as pharmaceuticals, food, and chemicals, monitoring product quality is crucial. High-precision weighing and inspection technology ensures that products meet stringent weight and quality standards during the production process. High-precision weighing and inspection typically employs advanced sensors and weighing equipment, such as electronic balances and weighing modules, combined with sophisticated software algorithms to achieve accurate measurement and control of product weight.

[0004] Patent Document 2 provides a chemical raw material output control device that directly feeds in lumps of chemical raw material, grinds it into powder, and then weighs and outputs it. However, the technical solution in Patent Document 2 can only process a limited variety of chemical raw materials, and requires grinding them into powder before outputting, resulting in low efficiency.

At the second position, the material package extraction mechanism is opposite to the clamping and rotating mechanism, which can receive the material package from the material package extraction mechanism.

[0021] Preferably, the size of the space formed by the plurality of baffles for storing the material package is adjustable.

[0022] Effects of the utility model

[0023] The dispensing device employing the technical solution of this application utilizes independently packaged material packets and multiple material packet storage mechanisms to accommodate various chemical reagents. It can prepare a variety of chemical reagents, and because the outlet is located in the upper storage mechanism, a baffle is not needed at the outlet, preventing material packets from getting stuck and difficult to remove, thus ensuring stable extraction of chemical reagents.

[0034] The following is a detailed description of the structure of this utility model based on the accompanying drawings. However, the following description is not intended to limit this utility model. Changes, substitutions, combinations, deletions, etc., can be made to the constituent elements of the technical solution without departing from the spirit of this application.

[0035] <Overall Structure of the Batching Device>

[0036] like Figure 1 As shown, the dispensing device of this application includes: a plurality of material package storage mechanisms 12a for storing material packages; a material package extraction mechanism 14a for selectively extracting desired material packages 38 from the plurality of material package storage mechanisms 12a; a first moving part 18a, which may include, for example, a guide rail and a drive motor 61, the guide rail guiding the material package extraction mechanism 14a to move, and the drive motor 61 providing driving force; and a clamping and rotating mechanism 15 for receiving material packages from the material package extraction mechanism 14a.

[0037] Material package 38 contains chemical reagents pre-ground into granules or powder, and multiple material package storage units 12a can store various types of material packages. Therefore, the material package extraction unit 14a can selectively extract material packages from the multiple material package storage units 12a according to the type of chemical reagent required. Furthermore, by using independent material packages to store chemical reagents and storing them separately in different material package storage units 12a, contamination between different types of chemical reagents can be avoided, and a predetermined amount of chemical reagent can be specified using the material packages.

[0038] like Figure 1 As shown, the dispensing device of this application also includes a dispensing plate 28 and a rotating plate 87. The dispensing plate 28 is located below the clamping and rotating mechanism 15. The rotating plate 87 is used to hold the reagent carrier container. The clamping and rotating mechanism 15 can pour the chemical reagents in the material package into the dispensing plate 28. The dispensing plate 28 guides the chemical reagents into the reagent carrier container held by the rotating plate 87, thereby completing the dispensing.

[0039] The batching device also has a worktable that provides stable support for the various batching mechanisms, ensuring stable support during the batching process. Furthermore, the batching device also has a controller that can control the various parts described later.

[0040] The following is a description of each part of the batching device.

[0041] <Material Package Storage Mechanism>

[0042] exist Figure 2 , Figure 3 The material package storage mechanism 12a of this application is shown in the figure. For example... Figure 2As shown, the material package storage mechanism 12a is used to store material packages 38. The material package storage mechanism 12a includes: a plurality of baffles 58a that surround (divide) a space for storing material packages, and an outlet 42a that is not blocked by the baffles above the space; a material package support 88a that supports the material package from below within the space; and a lifting mechanism 39 that enables the material package support 88a to move away from and towards the outlet 42a.

[0043] like Figure 2 As shown, multiple baffles 58a have a fixing part 70 integrally formed on their outer circumference, and the fixing part 70 is directly or indirectly fixed to the worktable (see reference). Figure 1 A rod 64 is installed through the fixed part 70. A material bag support part 88a is provided at the upper end of the rod 64. The material bag support part 88a is platform-shaped, thereby stably and reliably supporting the material bag. A movable part 65 is fixed at the lower end of the rod 64. Figure 3 As shown, the movable part 65 is threaded onto the threaded screw 67, the lower end of which is connected to the lifting mechanism 39. Driven by the lifting mechanism 39, the threaded screw 67 rotates, causing the movable part 65 to move up and down. As the movable part 65 moves up and down, the rod 64, along with the material bag support part 88a, moves up and down. This allows the material bag stored in the material bag storage mechanism 12a to be pushed upwards, facilitating the retrieval of the material bag by the material bag extraction mechanism 14a.

[0044] exist Figure 2 The design incorporates multiple baffles 58a arranged circumferentially with spacing between them. Compared to continuous circular baffles in the circumferential direction, this arrangement facilitates the cleaning and maintenance of the material package storage mechanism 12a. Furthermore, it allows operators to visually observe the material packages stored in the material package storage mechanism 12a through the gaps between the multiple baffles 58a, making it easier for users to identify the type of material package.

[0045] Preferably, the material package support 88a supports the material package horizontally, but it can also support it at an angle relative to the horizontal plane. In addition, the plurality of baffles 58a preferably extend vertically, and the material package support 88a moves vertically up and down. Of course, it is also possible that the plurality of baffles 58a extend at an angle, and the material package support 88a moves at an angle in the vertical direction.

[0046] <Material Package Extraction Mechanism>

[0047] exist Figure 4 The structure of the material package extraction mechanism 14a is shown in the figure. For example... Figure 4As shown, the material package extraction mechanism 14a includes: an extraction section 66a for extracting a material package 38 from an outlet section 42a; a cylinder 96a as a drive unit, which, with movement (extension and retraction) of the cylinder 96a, switches the extraction section 66a between a first state and a second state. In the first state, the extraction section 66a is positioned opposite the outlet section 42a to pick up the material package and extract the material package 38 from the outlet section 42a; in the second state, the extraction section 66a is in a state where it drives the material package away from the outlet section 42a; a connecting rod 94a to which the extraction section 66a is mounted, and the connecting rod 94a is connected to the cylinder 96a; and a fixing member 92a to which the connecting rod 94a is rotatably connected. A hydraulic cylinder may also be used instead of the cylinder 96a.

[0048] Specifically, such as Figure 4 As shown, one end of the connecting rod 94a is rotatably connected to the fixed member 92a, thereby allowing the connecting rod 94a to rotate about the point of connection with the fixed member 92a as a fulcrum. Figure 4 As indicated by the middle arrow, an extraction part 66a is installed at the other end of the connecting rod 94a. The piston rod 98a of the cylinder 96a is connected to the connecting rod 94a. As the cylinder 96a extends and retracts, the piston rod 98a is driven by the cylinder 96a to move, thereby causing the connecting rod 94a to rotate.

[0049] like Figure 4 As shown, the extraction section 66a has an extraction surface 71 that contacts the material package 38. In the first state, the extraction surface 71 is parallel to the plane containing the outlet section 42a, for example, in a horizontal state (here, the plane containing the outlet section 42a refers to the plane containing the material package 38 when it is stored in the material package storage mechanism 12a; for example, when the material package 38 is stored horizontally, even if the length of the baffle 58a is different, the plane containing the outlet section 42a is considered horizontal). In the second state, the extraction surface 71 is parallel to the inclined plane described later, for example, in a vertical state. The extraction section 66a can, for example, adsorb the material package using negative pressure. The term "parallel" here includes not only strictly parallel without intersecting surfaces, but also cases where it is close to parallel with a certain degree of error.

[0050] like Figure 4As indicated by the double-headed arrows, the extraction section 66a can swing with the rotation of the connecting rod 94a. That is, the extraction section 66a is configured to switch between a first state and a second state as the connecting rod 94a rotates. The first state is an inclined state (preferably a horizontal state) that matches the inclination of the material package support section 88a. In the first state, it is convenient for the extraction section 66a to extract the material package 38. The second state is an inclined state that matches the inclination of the clamping rotation mechanism 15 (the finger clamp). In the second inclined state, it is convenient for the extraction section 66a to transfer the material package 38 to the clamping rotation mechanism 15.

[0051] For example, when cylinder 96a extends piston rod 98a, connecting rod 94a rotates... Figure 4 The cylinder 96a rotates counterclockwise, causing the extraction section 66a to swing downwards until it is opposite (or parallel) to the outlet section 42a. Thus, the extraction section 66a receives the material package 38 from the outlet section 42a in a first state. When the cylinder 96a retracts the piston rod 98a, the connecting rod 94a rotates... Figure 4 When rotated clockwise, the extraction section 66a swings upward, achieving an angle of inclination (e.g., vertical) corresponding to the clamping rotation mechanism 15. Thus, the extraction section 66a enters its second state. Figure 4 The first and second states of the extraction unit 66a are shown in the diagram.

[0052] <Clamping and Rotating Mechanism>

[0053] exist Figure 5 The diagram shows a clamping and rotating mechanism 15 clamping a material package 38. (See attached diagram.) Figure 5 As shown, the clamping and rotating mechanism 15 has a clamping unit for receiving (clamping) a material package from the extraction section 66a. Figure 5 The diagram shows two clamping units, one including finger clips 151 and 152, and the other including finger clips 153 and 154. Finger clip 151 serves as the first finger clip, finger clip 152 as the second finger clip, finger clip 153 as the third finger clip, and finger clip 154 ​​as the fourth finger clip. It should be noted that the structure between finger clips 153 and 154 is the same as the structure between finger clips 151 and 152. Therefore, in the following description, there are instances where descriptions of finger clips 153 and 154 are omitted, but it is self-evident that the descriptions of finger clips 151 and 152 also apply to finger clips 153 and 154. Alternatively, only one clamping unit may be used.

[0054] The finger clip 152 can be configured to rotate relative to the finger clip 151, and the finger clip 154 ​​can be configured to rotate relative to the finger clip 153. Specifically, the finger clip 152 can rotate to approach or move away from the finger clip 151. When the finger clip 152 rotates to approach the finger clip 151, the material package 38 can be clamped by the finger clip 151 and the finger clip 152. When the finger clip 152 rotates to move away from the finger clip 151, the material package 38 can be released.

[0055] exist Figure 5 The diagram illustrates the structure when the material package 38 is held using the finger clips 151 and 152, and the structure when the material package 38 is released using the finger clips 153 and 154. When the finger clip 152 rotates close to the finger clip 151, the finger clip 152 can move while remaining parallel to the finger clip 151. That is, while keeping the finger clip 152 close to the finger clip 151, a misalignment occurs between the finger clips 152 and 151. Therefore, after the material package 38 is cut open using the cutting member 161, the finger clips 151 and 152 can be used to open the opening of the material package 38, facilitating the pouring out of the chemical reagents inside the material package 38.

[0056] Furthermore, the clamping unit composed of the finger clamps 151 and 152 can approach or move away from the clamping unit composed of the finger clamps 153 and 154. Thus, after the material package 38 is cut open by the cutting member 161, the relative movement between the two clamping units can be reliably used to open the opening of the material package 38, facilitating the pouring out of the chemical reagents in the material package 38.

[0057] like Figure 5 As shown, the clamping and rotating mechanism 15 has two rotation axes L1 and L2. Rotation axis L1 extends horizontally. When the clamping and rotating mechanism 15 rotates about rotation axis L1, it is equivalent to rotating the clamping units (clamps 151-154) in the vertical plane. Therefore, after the material package 38 is cut open using the cutting member 161, the material in the material package 38 can be emptied by rotating the clamping units (clamps 151-154) in the vertical plane. Rotation axis L2 extends vertically. When the clamping and rotating mechanism 15 rotates about rotation axis L2, it is equivalent to rotating the clamping units (clamps 151-154) in the horizontal plane. Therefore, the material package 38 can be rotated in the horizontal plane to the desired emptying position.

[0058] Furthermore, the rotation axis L1 may not extend strictly in the horizontal direction, but may be inclined relative to the horizontal direction. In this case, the clamping unit (clamps 151-154) rotates on the inclined surface that is inclined relative to the horizontal plane in a manner that allows the material package 38 to be inverted. After the material package 38 is cut open by the cutting member 161, the material in the material package 38 is poured out by rotating the clamping unit (clamps 151-154) on the inclined surface.

[0059] <Cutting Mechanism>

[0060] exist Figure 5 and Figure 7 The structure of the cutting mechanism 16a is shown in the figure, such as Figure 5 As shown, the cutting mechanism 16a has a cutting member 161, which is used to cut open the material package 38 held by the clamping and rotating mechanism 15 (clamping unit). After the material package 38 is cut open by the cutting member 161, the clamping unit (clamping 151 to 154) rotates in the vertical plane to pour out the material in the material package 38.

[0061] like Figure 7 As shown, the cutting mechanism 16a has a movable part 162 and a threaded screw 163. The cutting member 161 is fixed to the movable part 162, and the movable part 162 is threadedly connected to the threaded screw 163. By driving the threaded screw 163, the movable part 162 moves along the threaded screw 163, thereby driving the cutting member 161 to move.

[0062] The scissors used by the cutting component 161 can be pneumatic or electric. The cutting component 161 adjusts its cutting force and speed according to the material and size of the material package. The movement of the cutting component 161 is driven at different movement and cutting speeds depending on the material of the material package 38. The controller of the dispensing device ensures the accuracy and consistency of the cutting. Through the control of the controller, different types of material packages can be accurately and reliably cut, avoiding problems such as incomplete cutting and inaccurate dispensing due to inverted material packages.

[0063] The cutting mechanism 16a may also have a cover that can be removed during operation of the cutting mechanism 16a. After the material package 38 is cut, the cover is then used to cover the cutting blades of the cutting mechanism 16a again. This prevents material in the material package 38 from adhering to the cutting blades and inhibits contamination of the material by the cutting blades when cutting the material package.

[0064] <Drive mechanism>

[0065] A driving mechanism is used to move the material package extraction mechanism 14a so that the extraction unit 66a can be positioned corresponding to the material package storage mechanism 12a of the material package to be retrieved. The driving mechanism includes a first moving part 18a and a second moving part. The first moving part 18a is used to move the material package extraction mechanism 14a between a first position and a second position. At the first position, the material package extraction mechanism 14a can extract the material package from the corresponding material package storage mechanism 12a. At the second position, the material package extraction mechanism 14a is opposite to the clamping and rotating mechanism 15, which can receive the material package from the material package extraction mechanism 14a. The second moving part is used to drive the material package extraction mechanism 14a along a first direction (…). Figure 4 The first moving part 18a moves in a left-right direction, intersecting the direction of the line connecting the first and second positions. When both the first moving part 18a and the second moving part are simultaneously provided, and multiple material package storage mechanisms 12a are arranged in an array, the first moving part 18a and the second moving part can be utilized to allow the material package extraction mechanism 14a to move to a position corresponding to any one of the multiple material package storage mechanisms 12a. The drive mechanism may also have only the first moving part 18a.

[0066] When the material package extraction mechanism 14a is moved to the second position and the extraction part 66a is in the second state, the extraction part 66a is opposite to the clamping units 151 and 152 so that the clamping units 151 and 152 clamp the material package from the extraction part 66a.

[0067] In addition, such as Figure 1 and Figure 4 As shown, the first moving part 18a includes a guide rail and a drive motor 61. The guide rail guides the material package extraction mechanism 14a to move, and the drive motor 61 provides driving force for the movement of the material package extraction mechanism 14a. Figure 4 As shown, the second moving part includes: a slider 93 connected to a fixing member 92a, thereby fixing it to the material package extraction mechanism 14a; a track 91 on which the slider 93 can slide, and a driving member drives the slider 93 to slide, enabling the slider 93 to slide along... Figure 4 It slides left and right in the middle, and the track 91 extends along the first direction. Thus, when the material package storage mechanism 12a is arranged in an array (for example...), Figure 1The material package extraction mechanism 14a consists of two rows of material package storage mechanisms 12a. Based on the movement of the slider 93, the extraction part 66a of the material package extraction mechanism 14a can contact the multiple rows of material package storage mechanisms 12a. That is, the material package extraction mechanism 14a can move the extraction part 66a in directions relative to the material package storage mechanisms 12a, moving closer to or further away from them. Thus, the material package extraction mechanism 14a can handle multiple rows of material package storage mechanisms 12a. The drive member of the second moving part can be driven at any time as needed, as long as it does not interfere with other components. Furthermore, the track 91 is slidably connected to the guide rail. Here, slidable connection means that the track 91 can be guided by the guide rail to move between a first position and a second position, and / or the track can be guided by the track 91 to move along a first direction. The specific connection structure between the track 91 and the guide rail is not strictly limited, as long as it ensures that the material package extraction mechanism 14a can move in two intersecting directions within the plane.

[0068] The first moving part 18a moves, for example, through a transmission between a threaded screw and a gear, with the drive motor 61 providing power. The first and second positions of the material package extraction mechanism 14a are not strictly fixed. The first position is defined as the ability to accurately extract the material package 38 from the material package storage mechanism 12a, and the second position is defined as the ability to accurately receive the material package 38 from the clamping and rotating mechanism 15. For example, in the case of multiple material package storage mechanisms 12a, each material package storage mechanism 12a may have its own position for extracting the material package (the first position).

[0069] Preferably, after the extraction section 66a of the material package extraction mechanism 14a extracts the material package 38, the extraction section 66a first moves to the second state, and then the first moving section 18a moves it to the second position.

[0070] Based on the movement of the slider 93 of the material package extraction mechanism 14a and the movement guided by the first moving part 18a, the material package extraction mechanism 14a can handle multiple material package storage mechanisms 12a arranged in an array, and can further increase the number of material package storage mechanisms 12a and the types of material packages that can be stored. Of course, only one row of material package storage mechanisms 12a can be set. As long as there are multiple material package storage mechanisms 12a, different types of chemical reagent material packages can be used. In this case, only the first moving part 18a can be set without setting the slider 93 and the driving part for the material package extraction mechanism 14a.

[0071] <Distribution disk and rotating disk>

[0072] like Figures 6-8As shown, a rotatable distribution plate 28 is arranged below the clamping and rotating mechanism 15, and multiple hoppers 17 are provided on the distribution plate 28. The multiple hoppers 17 are used to collect materials (chemical reagents), and each hopper 17 corresponds to a different material. By assigning multiple hoppers 17 to different materials, only one type of material can be collected from each hopper 17, avoiding interference between different materials.

[0073] A rotatable rotating disk 87 and a weighing unit 30 are disposed below the dispensing disk 28 and on the side opposite to the clamping and rotating mechanism 15. The rotating disk 87 is capable of rotating in the horizontal plane. By positioning it in this way, the space below the dispensing disk 28 can be fully utilized without occupying additional space. The rotating disk 87 is used to hold the reagent carrier container 68.

[0074] like Figure 6 As shown, the rotating disk 87 is located below the distribution disk 28 and above the weighing unit 30. The rotating disk 87 and the distribution disk 28 overlap at least partially in the vertical direction, allowing the hopper 17 to guide material into the reagent carrier container 68 held on the rotating disk 87. The rotating disk 87 can support multiple reagent carrier containers in the circumferential direction. For example, multiple reagent carrier containers can be evenly distributed in the circumferential direction of the rotating disk 87. By rotating the rotating disk 87, one of the multiple reagent carrier containers supported on the rotating disk 87 can be positioned above the weighing unit 30 for weighing. Therefore, the rotating disk 87 can selectively position one of the multiple reagent carrier containers supported on the rotating disk 87 below the hopper 17 of the distribution disk 28 and above the weighing unit 30.

[0075] Specifically, such as Figure 6 , Figure 8 As shown, the rotating disk 87 includes an upper holding plate 291 and a lower holding plate 292. The upper holding plate 291 and the lower holding plate 292 are disc-shaped structures. The upper holding plate 291 and the lower holding plate 292 are connected by a drive and can rotate coaxially. The upper holding member 291 holds the side wall of the reagent carrying container 68. The upper holding plate 291 has a plurality of holding holes 2911 along its circumference for the reagent carrying container 68 to pass through. The lower holding member 292 holds the bottom wall of the reagent carrying container 68. The lower holding plate 292 has weighing holes 2921 along its circumference that correspond one-to-one with the holding holes 2911. The diameter (maximum radial length) of the weighing hole 2921 is smaller than the outer diameter (minimum outer radial length) of the reagent carrying container 68. The holding holes 2911 and the weighing holes 2921 constitute the holding member for holding the reagent carrying container 68. The rotating disk 87 can rotate so that any one of the weighing holes 2921 is located directly above the weighing unit 30.

[0076] The rotating disc 87 can hold multiple reagent carrier containers 68 that have been filled with other materials (materials for reacting with chemical reagents). By rotating, each container can be moved to a weighing station for weighing. For example, when the distribution disc 28 rotates to the weighing position (corresponding to the weighing unit 30), it can fill the corresponding reagent carrier container 68, weigh it, and then the rotating disc 87 can rotate again to move another reagent carrier container above the weighing station for feeding. Alternatively, it can be moved to the weighing position later, without feeding, thus improving efficiency and avoiding waiting for the reagent carrier containers to be moved to the weighing station. The rotation of the rotating disc 87 allows a reagent carrier container 68 to be positioned on the weighing unit 30, and the rotation of the distribution disc 28 allows a hopper 17 to be positioned above the reagent carrier container 68, guiding the material into the container. Of course, the material can also be poured in from a position other than the weighing unit 30 by rotating the rotating disk 87 and the dispensing disk 28 so that the specific reagent carrying container 68 is below and the specific hopper 17 is above. Thus, this series of operations can be completed efficiently when multiple materials are poured in and multiple reagent weights are measured, without waiting or idle workstations.

[0077] As described above, the reagent carrier container 68 placed on the rotating disk 87 can be added either at the weighing position or not at the weighing position. That is, the rotating disk 87 and the dispensing disk 28 overlap at least partially in the vertical direction, and the overlapping area includes both the weighing position and the non-weighing position.

[0078] like Figure 8 As shown, the weighing unit 30 is located below the lower holding plate 292. The outer diameter of the weighing unit 30 is smaller than that of the weighing hole 2921. Therefore, at least a portion of the weighing unit 30 can pass through the weighing hole 2921 and lift the reagent carrier container 68 to weigh the reagent carrier container 68. The lifting mechanism 69 can be used to drive the lifting and lowering of the weighing unit 30.

[0079] <Other Structures>

[0080] like Figure 5As shown, a waste collection device is provided below the position where the material package 38 is cut using the cutting member 161. This device collects the partial outer packaging of the cut material package and the outer packaging of the material package after the powder has been poured out. By placing the material pouring position and the material package cutting position at different locations, contamination of the ingredients by substances generated during the cutting process can be avoided. Alternatively, the clamping and rotating mechanism 15 can move horizontally instead of rotating. As long as the clamping and rotating mechanism 15 can deliver the clamped material package 38 above the desired location (all hoppers or a specific hopper), the movement method (rotation or translation) of the clamping and rotating mechanism 15 and the mechanism driving the movement of the clamping and rotating mechanism 15 are not limited.

[0081] Alternatively, the space for storing the material package 38, formed by multiple baffles 58a, can be adjusted in size. For example, the user can set different baffles as needed, such as setting baffles of different sizes onto the worktable in a removable or sliding manner. Thus, the baffles can be set as needed to accommodate material packages of different sizes.

[0082] Alternatively, hopper 17 may have an opening and closing device capable of sealing the outlet. With this configuration, material may not be poured into hopper 17 at the weighing position (the position corresponding to weighing unit 30), but rather into hopper 17 at other positions. At these other positions, the outlet of hopper 17 is sealed to prevent material leakage. When the distribution disc 28 rotates so that hopper 17 is above the weighing position, hopper 17 opens its outlet, allowing the material inside to leak out and enter the reagent carrier container 68 held on the rotating disc 87.

[0083] The dispensing device incorporates high-precision sensors or vision systems to ensure the correct position and orientation of the material package 38. The controller, based on feedback from the sensors or vision system, controls the extraction unit 66a, the first moving unit 18a, and the clamping rotation mechanism 15 to achieve precise dispensing.

[0084] The driving and control described above can all be performed through a controller.

[0085] <Workflow Based on the Batching Device>

[0086] The following is a brief description of the workflow of the batching device based on this application. However, the following process is only one example, and the workflow can be modified arbitrarily by utilizing the technical concept of this application, without contradicting the above description.

[0087] First, the first moving part 18a moves the material package extraction mechanism 14a to a first position. The extraction part 66a of the material package extraction mechanism 14a, driven by the cylinder 96a, enters a first state, thereby selectively extracting the required material package 38 from the multiple material package storage mechanisms 12a. After extraction is completed, the extraction part 66a, driven by the cylinder 96a, enters a second state.

[0088] Then, the first moving part 18a moves the material package extraction mechanism 14a to the second position, and the clamping and rotating mechanism 15 receives the material package 38 from the material package extraction mechanism 14a using its clamping unit (fingers 151-154), and cuts the material package 38 held by the fingers 151-154 using the cutting member 161. The clamping and rotating mechanism 15 rotates in the horizontal plane to above the weighing unit 30.

[0089] Then, the rotating disk 87 and the dispensing disk 28 are rotated as needed to ensure that the reagent carrying container 68 held by the rotating disk 87 is above the weighing unit 30, and the hopper 17 of the dispensing disk 28 is above the reagent carrying container 68. The "above" here can be directly above or approximately directly above, as long as the function can be achieved, there is no limitation.

[0090] Then, the finger clips 151-154 rotate in the vertical plane, the material package 38 is inverted, and a specific finger clip among the finger clips 151-154 moves to pry open the cut opening of the material package 38, so that the material (chemical reagent) in the material package 38 can be smoothly poured into the hopper 17 of the distribution plate 28. The hopper 17 gathers and guides the granular (even powder or block) material (chemical reagent) into the reagent carrier container 68 below. The weighing unit 30 accurately weighs the reagent carrier container 68 after the material has been added.

[0091] The above process completes the ingredient mixing. After mixing, the controller analyzes the weighing results, collects weighing data, and adjusts the dispensing amount to ensure that the quality of each dispensed powder meets requirements. After completing one batch of production, the system cleans and resets to prepare for the next batch.

[0092] <Effect>

[0093] The technical solution of this application can achieve the following effects.

[0094] The material package storage mechanism 12a of this application has an outlet 42a at the top, from which the material package retrieval mechanism 14a retrieves the material package 38. Compared with storage mechanisms with the outlet at the bottom, it is not necessary to install a baffle at the outlet to prevent the material package from falling off, thereby reliably retrieving the material package and suppressing the situation where the material package gets stuck at the outlet and is difficult to retrieve.

[0095] By using individually packaged material packets, various chemical reagents can be prepared and placed in different material packets, thus avoiding reactions between the chemical reagents. Furthermore, by placing various material packets in different material packet storage mechanisms 12a, the user only needs to extract the required chemical reagent from the specific material packet storage mechanism 14a. Therefore, this application can handle situations involving multiple chemical reagents.

[0096] Therefore, by adopting the structure of this application, chemical reagents (material packages) can be stably extracted for various chemical reagents. The material package extraction mechanism 14a is moved to a specific position (second position) by the first moving part 18a, and the extraction part 66a of the material package extraction mechanism 14a is rotated to a specific state (second state) by the cylinder 96a, thereby enabling the material package to be reliably output.

[0097] When introducing reagents into the container, multiple hoppers 17 are prepared so that each hopper 17 can only carry one type of chemical reagent, thus avoiding reactions between different chemical reagents.

[0098] Furthermore, since the quality of the chemical reagents in the material package can be predetermined, it is advantageous in ensuring the quality of the chemical reagents. Combined with a weighing unit, it is possible to further ensure that the quality of the chemical reagents during the dispensing process meets the standards. In addition, the precise cutting and powder-dispensing mechanism reduces powder waste and contamination, improves product purity and consistency, and reduces human error.

[0099] This invention's structure enables automated operation based on a controller, reducing manual labor and lowering labor costs. It also reduces waste of raw materials and product loss caused by improper operation.

[0100] Furthermore, some chemical reagents are harmful or pose safety risks. The automated structure of this invention can operate in a closed or isolated environment, reducing the health impact on operators and improving safety. Controller-based automated operation can also collect and record data in real time, helping to monitor the production process and quickly identify and resolve problems. Historical data analysis helps to continuously improve production processes, enhancing product quality and production efficiency. In short, the automated structure of this application not only improves production efficiency and product quality but also enhances operational safety and data management capabilities, while simultaneously helping to reduce costs and environmental impact, bringing comprehensive benefits to industries such as pharmaceuticals.
