Description

Technical Field

[0001] The utility model belongs to the technical field of medicine production and processing equipment, and particularly relates to automatic metering and filling equipment for medicine particles. Background Art

[0002] Pharmaceutical granule filling machines are commonly used automated packaging equipment in pharmaceutical companies, primarily used to fill various types of granular pharmaceuticals. Filling requires ensuring the same quantity of granules in each bottle. Currently, granular pharmaceutical metering and filling equipment primarily utilizes two metering principles: volumetric measurement and gravimetric measurement. Volumetric measurement utilizes the air release and fluidity of pharmaceutical granules for measurement. These are categorized into fixed-volume and variable-volume methods. Fixed-volume volumetric measurement measures pharmaceutical granules within a set volume range, while variable-volume volumetric measurement adjusts the metering volume and feeding time to meet specific requirements for both metering and packaging. Gravimetric measurement uses load cells to measure the weight of pharmaceutical granules. These methods include single-scale and dual-scale methods. Single-scale measurement uses a single electronic scale to load the material, while dual-scale measurement utilizes two electronic scales: one weighing scale measures the weight of the incoming pharmaceutical granules and the other weighs the packaging bag, minimizing errors.

[0003] However, whether it is volume measurement or weight measurement, it is defined by default that the weight or volume of each medicine is the same, and the purpose is to ensure that the number of medicine particles filled in each bottle is the same; however, for some granular medicines made of extracts, the water contained inside may continue to dissipate during the filling process, resulting in a decrease in the volume and weight of the granular medicines; in addition, for capsule-type medicines, there may be weight errors when filling the capsules with drug powder; so when the above situation exists, measuring by weight or volume may result in an increase or decrease in the number of filled medicine particles compared to the standard number.

[0062] An automatic metering and filling device for pharmaceutical granules, comprising: a storage box 11, a hopper 8, a fixed number of medicine taking plates 7, a negative pressure component and a moving component;

[0063] like Figure 1As shown, the moving assembly includes: an electric-controlled lifting rod 2, an electric-controlled rotating shaft 4 and a cross-bracing rod 5; the electric-controlled rotating shaft 4 is provided at the upper end of the lifting rod of the electric-controlled lifting rod 2, and one end of the cross-bracing rod 5 is horizontally connected to the electric-controlled rotating shaft 4; the above-mentioned electric-controlled lifting rod 2 can adopt a hydraulic lifting column, which is an existing product; the electric-controlled rotating shaft 4 is also an existing product; it belongs to the existing technology that can be mastered by those skilled in the art, and its detailed structure and working principle are not repeated here;

[0064] A medicine taking plate mounting sleeve 6 is provided near the other end of the cross brace 5 and below the cross brace 5, and a fixed number of medicine taking plates 7 are detachably mounted on the medicine taking plate mounting sleeve 6;

[0065] like Figure 3 As shown, the structure of the above-mentioned fixed number medicine taking plate 7 is as follows: the fixed number medicine taking plate 7 is hollow inside to form a suction space 702; a plurality of medicine suction holes 701 are opened on the lower bottom surface of the fixed number medicine taking plate 7; the medicine suction holes 701 are connected to the suction space 702; the number of medicine suction holes 701 is equal to the number of granular medicines to be filled, and the aperture of the medicine suction holes 701 is smaller than the aperture of the granular medicines to be filled, that is, the granular medicines will only be adsorbed on the medicine suction holes 701 and will not pass through the medicine suction holes 701 and be sucked into the suction space 702; according to the number of granular medicines filled each time, the number of medicine suction holes 701 corresponding to the number of medicine suction holes 701 is opened, and the fixed number medicine taking plate 7 with the corresponding number of medicine suction holes 701 is replaced before filling;

[0066] A mounting tube 703 is centrally provided on the upper surface of the fixed number medicine taking plate 7. The mounting tube 703 and the above-mentioned medicine taking plate mounting sleeve 6 are both hollow structures. The mounting tube 703 is detachably mounted in the medicine taking plate mounting sleeve 6. The interiors of the two are in communication, so that the detachable installation of the fixed number medicine taking plate 7 can be achieved. Figure 3 As shown, a threaded structure is provided on the outer wall of the mounting tube 703, and a corresponding threaded structure is also provided on the inner wall of the medicine dispensing plate mounting sleeve 6; the mounting tube 703 and the medicine dispensing plate mounting sleeve 6 are detachably connected by threaded engagement.

[0067] like Figure 1 As shown, a negative pressure assembly is provided above the cross brace 5, and the negative pressure assembly includes: a negative pressure pump 10 and a negative pressure suction pipe 9;

[0068] The suction port of the negative pressure pump 10 is connected to one end of a negative pressure suction pipe 9. The other end of the negative pressure suction pipe 9 passes through the cross brace 5 and is connected to the upper end of the medicine dispensing plate mounting sleeve 6. The negative pressure suction pipe 9 is a serpentine tube with a bending and telescopic structure to cooperate with the rotation and lifting movement of the cross brace 5.

[0069] like Figure 1As shown, a storage box 11 is provided on the left side of the fixed number medicine dispensing plate 7, and the processed granular medicine to be filled is placed in the storage box 11; a hopper 8 is provided directly below the fixed number medicine dispensing plate 7, with a large opening at the upper end and a narrow opening at the lower end discharge port, which facilitates the collection of the input medicine and the filling into the material bottle 3; as a preferred embodiment, a detachable injection nozzle 801 is provided on the discharge port below the hopper 8, and the inner and outer diameters of the injection nozzle 801 gradually decrease from the upper end opening to the lower end opening; the overall structure is funnel-shaped. The lower end of the injection nozzle 801 can be extended into the material bottle mouth, making the filling more accurate.

[0070] A conveying mechanism 1 is provided directly below the hopper 8. The empty material bottles 3 are conveyed on the conveying mechanism 1 toward the hopper 8. The conveying mechanism 1 includes: a transmission shaft 101 and a conveyor belt 102.

[0071] A plurality of transmission shafts 101 are provided on the conveying plane; a transmission motor is provided on at least one transmission shaft 101 at both ends of the conveyor belt 102; the transmission motor is used to provide a power source for transmission; a conveyor belt 102 is provided on the plurality of transmission shafts 101, and the transmission motor drives the transmission shaft 101 to rotate, thereby driving the conveyor belt 102 for transmission;

[0072] At least one set of support bases 103 is set between the upper and lower conveyor belts 102, and the upper and lower surfaces of the support bases 103 are respectively in contact with the upper and lower conveyor belts 102; a set of support bases 103 is set at the position opposite to the hopper 8.

[0073] The transmission motor for driving the transmission shaft 101 is communicatively connected to the PLC. The empty material bottles 3 to be filled are placed on the conveyor belt 102 and conveyed toward the hopper 8. When an empty material bottle 3 is conveyed to the bottom of the hopper 8, the PLC controls the conveyor belt 102 to pause conveying. When the filling is completed, the PLC controls the conveyor belt 102 to continue conveying.

[0074] The working process of drug infusion is as follows:

[0075] The electric-controlled rotating shaft 4 drives the fixed number medicine-taking plate 7 to rotate to the top of the storage box 11, and then the electric-controlled lifting rod 2 drives the fixed number medicine-taking plate 7 to descend into the storage box 11; the negative pressure pump 10 starts to suck the air in the fixed number medicine-taking plate 7, so that a negative pressure is formed inside the fixed number medicine-taking plate 7, and the granular medicine is sucked to the lower bottom surface of the fixed number medicine-taking plate 7, and only the medicine-sucking holes 701 will produce a negative pressure attraction effect on the granular medicine. Then, how many medicine-sucking holes 701 are opened on the bottom surface of the fixed number medicine-taking plate 7, how many medicines will be adsorbed, and this number is The amount of medicine that needs to be metered and infused; after the medicine is firmly adsorbed, the electric-controlled rotating shaft 4 rotates in the opposite direction, driving the fixed-number medicine-taking plate 7 to rotate synchronously. When it rotates to just above the hopper 8, the negative pressure pump 10 is powered off; the negative pressure suction effect disappears, and at this time, the medicine on the bottom of the fixed-number medicine-taking plate 7 will all fall into the hopper 8 and be poured into the material bottle 3 just below from the discharge port of the hopper 8; the filled material bottle 3 is conveyed forward, and an empty material bottle 3 at the back is about to fill its place; in this process, the fixed-number medicine-taking plate 7 will repeat the work of taking medicine again.

[0076] Example 2

[0077] Based on Example 1, in Example 1, the mounting tube 703 above the fixed number medicine dispensing plate 7 is detachably connected to the medicine dispensing plate mounting sleeve 6 by threaded fitting, thereby realizing the detachable installation of the fixed number medicine dispensing plate 7; however, the threaded fitting connection method is more troublesome during installation or disassembly, and requires repeated screwing; and if the threaded fitting is not in place, deflection may occur.

[0078] like Figure 4 As shown, in this embodiment, two elastic nail grooves 7032 are symmetrically provided on the side wall of the mounting tube 703; elastic staples 7034 are movably provided in the two elastic nail grooves 7032; an elastic member 7033 is provided between the tail end of the elastic staple 7034 and the elastic nail groove 7032, wherein the elastic member 7033 can be a spring; elastic nail through holes are symmetrically provided on the side wall of the medicine dispensing plate mounting sleeve 6; the mounting tube 703 is installed in the medicine dispensing plate mounting sleeve 6, and the elastic staples 7034 are automatically engaged in the elastic nail through holes, thereby connecting and fixing the mounting tube 703 to the medicine dispensing plate mounting sleeve 6. When the two need to be disassembled, it is only necessary to press the elastic staple 7034 to retract the elastic staple 7034 from the elastic nail channel into the elastic nail groove 7032, and then the mounting tube 703 can be pulled out from the medicine dispensing plate mounting sleeve 6 to complete the disassembly.

[0079] Example 3

[0080] Based on Example 1, in Example 1, the fixed number medicine taking plate 7 adsorbs the medicine particles from the storage box 11 on the medicine suction holes 701 through negative pressure adsorption, and then transfers them to the hopper 8; however, during the medicine taking process, it may happen that one or several of the medicine suction holes 701 do not adsorb the granular medicine; at this time, if it continues to be transferred to the hopper 8, the amount of medicine finally poured into the material bottle 3 will be inaccurate.

[0081] like Figure 1 and Figure 7 As shown, in this embodiment, a visual inspection platform 12 is provided between the storage box 11 and the hopper 8, and at the rear side of the mobile component; an image capture camera 1201 is provided in the center of the upper surface of the visual inspection platform 12; and the image capture camera 1201 is communicatively connected to the PLC. When the fixed number of medicine dispensing plate 7 absorbs the medicine and transfers it to the hopper 8, it will pass directly above the visual inspection platform 12. At this time, the image capture camera 1201 collects the image of the bottom surface of the fixed number of medicine dispensing plate 7 and feeds the image information into the PLC. The PLC recognizes and processes the image information to determine whether all the medicine particles are adsorbed on the medicine suction holes 701, or whether there is leakage; if there is leakage, the PLC will drive the mobile component of the fixed number of medicine dispensing plate 7 to return to the storage box 11 to re-dispense the medicine until the amount of medicine taken meets the requirements.

[0082] Example 4

[0083] Based on Example 1, in Example 1, by taking out medicine in fixed quantities, each material bottle 3 is filled with the same number of medicines;

[0084] In order to further verify the quantity of the medicine, this embodiment is based on the direct measurement of the quantity of the granular medicine in Example 1, and also retains the function of using weight to verify;

[0085] like Figure 6 As shown, the filling position is set directly opposite the hopper 8. A pressure sensor 13, a patch pressure sensor, is installed on the upper surface of the support base 103 provided at the filling position. The pressure sensor 13 contacts the upper conveyor belt 102. After the material is transported to the filling position and filling is completed, the pressure sensor 13 is subjected to the combined pressure of the material bottle 3 and the drug. The collected pressure signal is fed into the PLC, which processes the pressure signal into weight information and eliminates the weight of the empty material bottle to obtain the weight of the filled drug. If the weight differs significantly from the set threshold, the PLC issues a prompt message at the terminal, prompting the staff to conduct a comprehensive inspection of the equipment and check for any faults.
