Description

Technical Field

[0001] This invention belongs to the field of preparation of hazardous agents for pyrotechnics, and specifically relates to a rotary agent mixing and dispensing machine. Background Technology

[0002] Pyrotechnics are a general term for disposable components and devices that, upon being stimulated by external stimuli, ignite gunpowder, detonate explosives, or perform mechanical work. The composite agent coating a pyrotechnic plays a crucial role in ensuring its reliable explosion or combustion.

[0003] Because the agents used in pyrotechnics are detonators or igniters, their high energy and high sensitivity make their preparation process extremely risky. Currently, the preparation of pyrotechnic agents in China requires manual removal of large quantities of agents from a dedicated temporary storage room and manual transfer to the production area. In addition, the agents need to be divided into smaller quantities according to process requirements in an explosion-proof room with certain explosion-proof capabilities and then manually transferred to the assembly station for assembly.

[0004] This operating method currently has the following problems:

[0005] 1) Frequent manual entry and exit from the explosion-proof room is required, the production process is outdated, and the labor intensity is high;

[0006] 2) Each loading process is manually controlled, resulting in low product quality.

[0007] 3) The process of dispensing medicine involves direct contact between humans and large quantities of medicine, posing an extremely high safety risk;

[0008] Therefore, there is a need to design a rotary drug mixing and dispensing machine. Except for manual handling of the drug cups, all other processes are continuous and automated, eliminating direct contact between humans and large quantities of hazardous dry drugs. Furthermore, certain technological means ensure accurate and controllable drug loading, solving the problems of high labor intensity, high labor costs, uncontrollable product quality, and low inherent safety of current manual labor. Moreover, the machine is multi-functional and suitable for dispensing and adding various types of drugs and different types of drug cups. Summary of the Invention

[0009] The purpose of this invention is to provide a rotary pharmaceutical mixing and dispensing machine to solve the problems of high labor intensity, high labor costs, uncontrollable product quality, and low inherent safety in current manual labor.

[0010] This invention is achieved through the following technical solutions;

[0012] The automatic feeding mechanism for empty medicine cups includes an interlocked transfer window and an automatic feeding mechanism for empty medicine cups. The interlocked transfer window consists of a set of sliding doors installed on opposite sides and a protective steel barrel. During operation, only one side door is opened and closed. The automatic feeding mechanism for empty medicine cups includes multiple sets of cylinders that can work together to perform gripping, lifting, and rotating operations.

[0013] The automatic feeding and receiving mechanism for large medicine cups includes an interlocked transfer window and a large medicine cup feeding mechanism. The interlocked transfer window is equipped with a medicine cup placement platform. The large medicine cup feeding mechanism includes a feeding cylinder, a rotary cylinder, and an extension cylinder.

[0014] The drug mixing and dispensing mechanism includes a workbench, a transmission module, a dispensing mechanism support, and a rotating large medicine barrel. The transmission module is located on one side of the workbench below the workbench surface. A medicine cup placement tray is provided on the sliding end of the transmission module. The dispensing mechanism support and the rotating large medicine barrel are both located on the upper end of the workbench surface. One end of the rotating large medicine barrel is connected to a rotating shaft. The rotating shaft is connected to a self-rotating motor via a coupling. The self-rotating motor and the rotating shaft are both fixed to a U-shaped support. The U-shaped support is connected to the dispensing mechanism support via two connecting shafts on its left and right sides. On one side of the dispensing mechanism support, one end of the connecting shaft is connected to a planetary motor via a coupling.

[0015] The drug mixing and dispensing mechanism has a transition funnel at the lower end of the rotating large drug cylinder, which is connected to the dispensing mechanism support via a funnel fixing frame. A funnel adjusting base is provided between the transition funnel and the funnel fixing frame. The funnel adjusting base has a conical hollow center for holding the transition funnel. The bottom of the funnel adjusting base is connected to the funnel fixing frame by a snap-fit ​​structure. The transition funnel has an elliptical structure, which is larger at the top and smaller at the bottom. A baffle is provided at the top of the transition funnel, and a dust cover is provided at the bottom.

[0016] The drug mixing and dispensing mechanism has a weighing sensor at the lower end of the transition funnel. One end of the sensor is connected to a weighing lifting cylinder via a connecting plate. The stroke of the weighing lifting cylinder is adjustable. At the weighing end of the weighing sensor, there is a weighing tray with a hollow bottom center. Two sets of L-shaped claws of different lengths are provided around the tray, and multiple sets of detachable limiting pins are provided on the outer edge of the claws.

[0017] The drug mixing and dispensing mechanism uses a high-precision weighing sensor as the weighing unit. A sensor base plate is provided at the bottom of the weighing sensor, and an upper protective sleeve is provided at the top of the weighing sensor.

[0018] The rotating shaft of the drug mixing and dispensing mechanism is connected to a large rotating medicine tank at one end, which is a hollow disc-shaped structure. A symmetrical arc-shaped groove is provided at one end of the disc. The other end of the rotating disc is provided with two threaded holes for installing quick-release pins. A limit pin is also provided on the disc. The bottom of the large rotating medicine tank is provided with an arc-stepped shaft, and a fan-shaped baffle is symmetrically provided at the end of the stepped shaft to cooperate with the arc-shaped groove of the rotating shaft. The baffle is symmetrically provided with insertion holes that cooperate with the two threaded holes of the rotating disc.

[0019] The drug mixing and dispensing mechanism has two sets of grooves with different structural shapes on the left and right sides of the front end of the medicine cup placement tray, and a cross-shaped elongated hole is provided in the middle of each groove.

[0020] The present invention provides a rotary pharmaceutical mixing and dispensing method, comprising the following steps:

[0021] 1) Set the selected dispensing cup and the amount of medicine to be dispensed via the touchscreen;

[0022] 2) The large medicine cup feeding mechanism grabs the large medicine cup in the transfer window and places it above the medicine mixing and dispensing mechanism, adding the medicine into the rotating large medicine tank to complete the dispensing process;

[0023] 3) The rotating motor of the drug mixing and dispensing mechanism drives the large medicine tank to rotate, thereby mixing the drugs;

[0024] 4) The automatic empty medicine cup feeding mechanism uses an automatic empty medicine cup feeding mechanism to grab the empty medicine cups in the transfer window and place them on the corresponding workstation of the medicine cup placement tray of the transfer module;

[0025] 5) The transfer module delivers the empty medicine cup to the drug mixing and dispensing mechanism station. The lifting cylinder drives the weighing sensor to pull the medicine cup on the module tray up to the lower end of the transition funnel for quantitative dispensing. After dispensing, the specific weighing value is fed back to the PLC.

[0026] 6) The transfer module sends the medicine cup to the loading position again, and the empty medicine cup automatic feeding mechanism sends the medicine cup on the transfer module to the transfer window; at this time, the operator can collect it directly outside the workshop according to production needs.

[0027] 7) After production is completed, the large medicine cup feeding mechanism drives the large medicine cup to the lower end of the transition funnel, collects all the remaining medicine in the rotating large medicine barrel into the large medicine cup, and sends the large medicine cup with the remaining medicine collected back to the transfer window.

[0036] To better illustrate the objectives, technical solutions, and advantages of the present invention, further explanation is provided below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of the technical effects of the present invention and are not intended to limit the scope of protection of the present invention.

[0037] like Figure 1 As shown, a rotary medicine mixing and dispensing machine of the present invention includes a large medicine cup automatic feeding and receiving mechanism 1, an empty medicine cup automatic feeding and receiving mechanism 3, and a medicine mixing and dispensing mechanism 2.

[0038] like Figure 2As shown, the automatic empty cartridge cup feeding mechanism 3 is used to realize the automatic transfer and feeding of empty cartridge cups. It includes an interlocked transfer window 302, a stepping mechanism 304, and an automatic empty cartridge cup feeding mechanism 301. The stepping mechanism 304 is set inside the interlocked transfer window 302. The interlocked transfer window 302 consists of a set of sliding doors 303 installed on opposite sides and a protective steel barrel 305. When the interlocked transfer window 302 is working, only one side door is opened and closed, which is to completely isolate the manual operation area from the production work area, and play a role in explosion protection and sympathetic explosion prevention. The stepping mechanism 304 includes a temporary storage platform and a stepping feeding claw, which can realize the temporary storage of multiple cartridge cups. After the first cartridge cup is picked up, with the help of the combined action of the lifting cylinder and the lateral movement cylinder, the stepping feeding claw transports the subsequent multiple cartridge cups forward in sequence, completing the sequential feeding and automatic synchronous conveying of empty cartridge cups.

[0039] The automatic empty medicine cup feeding mechanism 301 utilizes the coordinated action of multiple sets of cylinders to achieve bidirectional transmission of medicine cups within the production work area through gripping, lifting, and rotating operations.

[0040] like Figure 3 As shown, the automatic feeding and receiving mechanism 1 for large medicine cups is used to realize the functions of automatic feeding, automatic medicine pouring, automatic collection of residual medicine, and automatic receiving of large medicine cups. It includes an interlocking transfer window 101 and a large medicine cup feeding mechanism 102. The interlocked transfer window 101 is equipped with a medicine cup placement platform; the large medicine cup feeding mechanism 102 includes a feeding cylinder, a rotary cylinder, and an extension cylinder 103. When the feeding cylinder rises and the extension cylinder 103 extends, the medicine in the large medicine cup is poured into the rotating large medicine tank 414, realizing the medicine pouring function; when the feeding cylinder falls back and the extension cylinder 103 extends, the large medicine cup is located directly below the transition funnel 413. With the help of the medicine mixing and dispensing main mechanism 403, the medicine in the rotating large medicine tank 411 is recovered into the large medicine cup, realizing the residual medicine collection function; at the same time, the extension cylinder 103 retracts and the rotary cylinder returns to the center, sending the large medicine cup to the interlocked transfer window 101, realizing the medicine cup receiving function.

[0041] like Figure 4 , Figure 5As shown, the drug mixing and dispensing mechanism 2 includes a main drug mixing and dispensing mechanism 403, which includes a workbench 404, a transmission module 402, a dispensing mechanism support 419, and a rotating large medicine tank 411. The transmission module 402 is located at the lower end of the workbench 404 and on one side of the workbench 404 to prevent the medicine powder from falling onto the transmission module during the dispensing process. A medicine cup placement tray 401 is provided on the sliding end of the transmission module 402. The dispensing mechanism support 419 and the rotating large medicine tank 411 are both located on the upper end of the workbench 404. One end of the rotating large medicine tank 411 is connected to a rotating shaft 415. The rotating shaft 415 is connected to a self-rotating motor 418 via a coupling. The self-rotating motor 418 and the rotating shaft 415 are both fixedly connected to a U-shaped support 417. The U-shaped support 417 is connected to the dispensing mechanism support 419 via two connecting shafts on its left and right sides. On one side of the dispensing mechanism support 419, one end of the connecting shaft is connected to a revolution motor 412 via a coupling. The rotation of the self-rotating motor 418 can drive the rotating large medicine tank 411 to rotate, thereby achieving the mixing of the medicines inside the rotating large medicine tank 411.

[0042] The main dispensing and dosage-setting mechanism 403 for drug mixing includes a transition funnel 409 at the lower end of the rotating large medicine cylinder 411. This transition funnel 409 is connected to the dispensing mechanism support 419 via a funnel fixing frame 410. A funnel adjusting base 408 is positioned between the transition funnel 409 and the funnel fixing frame 410. The funnel adjusting base 408 has a conical hollow center to hold the transition funnel 409. The bottom of the funnel adjusting base 408 is connected to the funnel fixing frame 410 via a snap-fit ​​structure. The transition funnel 409 has an elliptical structure, wider at the top and narrower at the bottom. A retaining rim is provided at the top of the transition funnel 409, and a dust cover 407 is provided at its bottom. This design allows for quick replacement of different funnel adjusting bases 408 and transition funnels 409, meeting the needs of various product applications.

[0043] The main dispensing and dosage-setting mechanism 403 for drug mixing includes a weighing unit at the lower end of the transition funnel 409. This unit includes a high-precision weighing sensor 405, one end of which is connected to a weighing lifting cylinder 414 via a connecting plate. The stroke of the weighing lifting cylinder 414 is adjustable. At the weighing end of the high-precision weighing sensor 405, a weighing tray 406 is provided. This tray has a hollow bottom center and two sets of L-shaped claws of varying lengths around its perimeter. Multiple sets of detachable limiting pins are located on the outer edges of the claws, allowing for the placement of dispensing cups of different shapes and structures. The hollow bottom of the weighing tray 406 can hold small round cups, while irregularly shaped cups can be placed at the upper end of the L-shaped claws by adjusting the position and number of limiting pins. During the operation, the placement position of the medicine cup on the weighing tray 406 can be selected according to the shape of the medicine cup used. For small medicine cups with height differences, the cylinder stroke of the weighing lifting cylinder 414 can be adjusted to ensure that the medicine cups are lifted to the same height.

[0044] like Figure 5 As shown, the main dispensing mechanism 403 for mixing and dispensing the medicine uses a high-precision weighing sensor 405 as its weighing unit, which is highly sensitive. Therefore, a sensor base plate 421 is provided at the bottom of the weighing sensor 405, and an upper protective sleeve 420 is provided at the top of the weighing sensor to ensure that the high-precision weighing sensor 405 will not fail even when it is deformed by external force; at the same time, it can prevent human damage to the high-precision weighing sensor 405 during maintenance.

[0045] like Figure 6 As shown, the main dispensing mechanism 403 for mixing and dispensing the medicine has a hollow disc-shaped structure at one end of the rotating shaft 415 connected to the rotating medicine tank 411, which facilitates quick disassembly of the large medicine tank 411. A symmetrical arc-shaped groove 424 is provided at one end of the disc, and two threaded holes are provided at the other end of the disc for installing quick-release pins 416. A limit pin 423 is also provided on the disc. A stepped shaft is provided at the bottom of the rotating medicine tank 411, and symmetrical fan-shaped baffles 422 are provided at the ends of the stepped shaft. The fan-shaped baffles 422 have symmetrically provided insertion holes. During use, first insert the fan-shaped baffle 422 of the bottom stepped shaft of the rotating large medicine barrel 411 into the arc-shaped groove 424 of the disc of the rotating shaft 415. Then rotate the rotating large medicine barrel 411. With the help of the limiting pin 423, ensure that the rotating large medicine barrel 411 rotates into place. At this time, the insertion hole on the fan-shaped baffle 422 is completely aligned with the quick release pin 416. Manually open the quick release pin 416 and quickly insert it into the insertion hole to complete the fixation of the rotating large medicine barrel 411.

[0046] The main dispensing mechanism 403 for mixing and dispensing the medicine has two sets of grooves with different structural shapes on the left and right sides of the front end of the medicine cup placement tray 401, which can hold small medicine cups of different shapes. Each groove also has a cross-shaped elongated hole in the center. The cross-shaped elongated hole can cooperate with the weighing tray 406. At the start of operation, the medicine cup placement tray 401 is brought to the underside of the transition funnel 409 via the transfer module 402. The weighing lifting cylinder 414 lifts the weighing tray 406, and the L-shaped drag claws of the weighing tray 406 can lift the medicine cups in the medicine cup placement tray 401 through the cross-shaped elongated hole to the underside of the transition funnel 409 for dispensing. After dispensing, the weighing tray 406 places the medicine cups back into the medicine cup placement tray 401.

[0047] like Figure 5 As shown, the main dispensing mechanism 403 for mixing and dispensing the medicine includes two steps: coarse dispensing and fine dispensing, in order to ensure quantitative dispensing of the medicine. When the transfer module 402 brings the medicine cup to the dispensing station, the weighing lifting cylinder 414 lifts the weighing sensor 405, transferring the medicine cup from the medicine cup placement tray 401 of the transfer module 402 to the weighing tray 406 of the weighing sensor 405, until the weighing lifting cylinder 414 lifts the medicine cup to the lower edge of the transition funnel 409, at which point the weighing sensor 405 performs a tare operation. Next, while the rotating medicine barrel 411 rotates on its own axis, the orbital motor 412 drives the rotating medicine barrel 411 to start pouring medicine at a relatively fast speed until the weighing sensor 405 weighs close to the set value. This process is the coarse separation stage. Then, the orbital motor 412 stops rotating, and only the self-rotating motor 418 rotates at a slow and uniform speed. While continuing to rotate and mix the medicine in the rotating medicine barrel 411, the powder on the edge of the rotating medicine barrel 411 is sent into the medicine cup by means of inertia and rotational friction. When the weighing sensor 405 weighs less than 1g away from the set value, the self-rotating motor 418 stops rotating, ensuring that the residual medicine in the air enters the medicine cup, thus completing the medicine distribution operation. This process is the fine separation stage.

[0048] The present invention provides a rotary pharmaceutical mixing and dispensing machine, comprising the following steps:

[0049] 1) Set the selected dispensing cup and the amount of medicine to be dispensed via the touchscreen;

[0050] 2) The large medicine cup feeding and receiving mechanism 1 grabs the large medicine cup in the interlocked transfer window 101 and places it above the main body mechanism 403 for mixing and dispensing medicine, and adds the medicine into the rotating large medicine tank 411 to complete the medicine pouring;

[0051] 3) The self-rotating motor 418 of the main mechanism 403 for mixing and dispensing medicine drives the rotating large medicine barrel 411 to rotate, thereby mixing the medicine.

[0052] 4) The empty medicine cup automatic feeding mechanism 301 uses the empty medicine cup automatic feeding mechanism 301 to grab the empty medicine cup in the interlock transfer window 302 and place it on the corresponding station of the medicine cup placement tray 401 of the transfer module 402.

[0053] 5) The transmission module 402 sends the empty medicine cup to the main body mechanism 403 for mixing and dispensing medicine. The weighing lifting cylinder 414 drives the weighing sensor 405 to lift the medicine cup placed on the tray 401 to the lower end of the transition funnel 409 for quantitative dispensing. After the dispensing is completed, the weighing sensor 405 feeds back the specific weighing value to the PLC.

[0054] 6) The transmission module 402 sends the medicine cup to the feeding position again, and the empty medicine cup automatic feeding mechanism 301 sends the medicine cup on the transmission module 402 to the transfer window 302; at this time, the manual can collect it directly outside the workshop according to production needs.

[0055] 7) After production is completed, the large medicine cup feeding mechanism drives the large medicine cup to the lower end of the transition funnel 409, and collects all the remaining medicine in the rotating large medicine barrel 411 into the large medicine cup, and sends the large medicine cup with the remaining medicine collected back to the transfer window 101.
