[0036] In order to better illustrate the purpose, technical solutions and advantages of the present invention, further description is given below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to illustrate the technical effects of the present invention, rather than to limit the protection scope of the present invention.

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

[0038] like Figure 2As shown, the automatic feeding and loading mechanism 3 for empty medicine cups is used to realize the automatic transfer and automatic loading of empty medicine cups. It includes a set of interlocking transfer windows 302, a set of stepping mechanisms 304, and a set of automatic loading mechanisms 301 for empty medicine cups. The stepping mechanism 304 is arranged in the interlocking transfer window 302. The interlocking transfer window 302 is composed of a set of sliding doors 303 installed on the opposite sides and a protective steel barrel 305. When the interlocking transfer window 302 is working, only one side door is opened and closed. Its purpose is to completely isolate the manual operation area from the production work area, and play a role of explosion-proof and sympathetic explosion prevention. The stepping mechanism 304 includes a set of temporary storage platforms and step feeding claws, which can realize the temporary storage of multiple medicine cups. When the first medicine cup is finished grabbing, with the help of the joint action of the lifting cylinder and the lateral movement cylinder, the step feeding claws are used to transport the multiple medicine cups behind in sequence, completing the sequential loading and automatic synchronous transportation of the empty medicine cups.

[0039] The automatic empty medicine cup feeding mechanism 301 utilizes the synergistic effect of multiple groups of cylinders to achieve bidirectional transmission of medicine cups in the production work area through grabbing, lifting and rotating operations.

[0040] like Figure 3 As shown, the large medicine cup automatic feeding and receiving mechanism 1 is used to realize the functions of automatic feeding, automatic pouring, automatic residual medicine collection and automatic receiving of the large medicine cup, and comprises a set of interlocking transfer windows 101 and a set of large medicine cup feeding mechanism 102. The interlocking transfer window 101 is provided with a medicine cup placement platform; the large medicine cup loading mechanism 102 comprises a feeding cylinder 105, a rotating cylinder 104, and an extending cylinder 103. When the feeding cylinder 105 is lifted and the extending cylinder 103 is extended, the medicine in the large medicine cup is poured into the rotating large medicine barrel 414 to realize the medicine pouring function; when the feeding cylinder 105 falls back and the extending cylinder 103 is extended, the large medicine cup is located directly below the transition funnel 413, and the medicine in the rotating large medicine barrel 411 is recovered into the large medicine cup by means of the medicine mixing and metering medicine dispensing main mechanism 403 to realize the residual medicine collection function; at the same time, the extending cylinder 103 is retracted, the rotating cylinder 104 is returned to the normal position, and the large medicine cup is sent to the interlocking transfer window 101 to realize the medicine cup collecting function.

[0041] like Figure 4 , Figure 5As shown, the medicine mixing and metering dispensing mechanism 2 includes a medicine mixing and metering dispensing main mechanism 403, which includes a workbench 404, a transmission module 402, a dispensing mechanism bracket 419, and a rotating large medicine barrel 411. The transmission module 402 is arranged at the lower end of the workbench 404 and on one side of the workbench 404 to prevent medicine powder from scattering on the transmission module during the dispensing process; a medicine cup placement tray 401 is arranged on the sliding end of the transmission module 402. The medicine dispensing mechanism bracket 419 and the rotating medicine barrel 411 are both arranged at the upper end of the workbench 404, and one end of the rotating medicine barrel 411 is connected to the rotating shaft 415; the rotating shaft 415 is connected to the self-rotating motor 418 through a coupling; the self-rotating motor 418 and the rotating shaft 415 are both fixedly connected to the "X"-shaped bracket 417; the "X"-shaped bracket 417 is connected to the medicine dispensing mechanism bracket 419 through two connecting shafts on the left and right sides; on one side of the medicine dispensing mechanism bracket 419, one end of the connecting shaft is connected to the revolving motor 412 through a coupling. The rotation of the self-rotating motor 418 can drive the rotating medicine barrel 411 to rotate, so as to achieve the mixing of the medicine in the rotating medicine barrel 411.

[0042] The main mechanism 403 for mixing and dosing medicines is provided with a transition funnel 409 at the lower end of the rotating large medicine barrel 411, which is connected to the medicine dispensing mechanism bracket 419 through a funnel fixing frame 410, and a funnel adjustment base 408 is provided between the transition funnel 409 and the funnel fixing frame 410; the middle part of the funnel adjustment base 408 is conical and hollow, which is used to hold the transition funnel 409, and the bottom of the funnel adjustment base 408 is connected to the funnel fixing frame 410 in a buckled structure; the transition funnel 409 adopts an elliptical structural design, with a large upper end and a small bottom, and a retaining edge is provided at the upper end of the transition funnel 409, and a dust cover 407 is provided at its bottom. In this way, the blocked funnel adjustment base 408 and the transition funnel 409 can be quickly replaced to meet the use functions of various products.

[0043] The main mechanism 403 for mixing and dosing medicines is provided with a weighing unit at the lower end of the transition funnel 409, including a high-precision weighing sensor 405, one end of which is connected to a weighing lifting cylinder 414 through a connecting plate, and the weighing lifting cylinder 414 has an adjustable stroke; at the weighing end of the high-precision weighing sensor 405, a weighing tray 406 is provided, and its structure is hollow in the middle of the bottom, and two groups of L-shaped claws of different lengths are provided around it, and multiple groups of detachable limit pins are provided on the outer edge of the claws, which can accommodate medicine cups of different structures and shapes. The hollow bottom part of the weighing tray 406 can be used to place a small round medicine cup, and at the upper end of the L-shaped claw, a small medicine cup of an irregular shape can be placed by adjusting the position and number of the limit pins. During 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 used are lifted to the same height.

[0044] like Figure 5 As shown, the medicine mixing and dosing main mechanism 403 uses a high-precision weighing sensor 405 as the weighing unit, which has high sensitivity. Therefore, a sensor bottom plate 421 is provided at the bottom of the weighing sensor 405, and an upper sheath 420 is provided at the upper end of the weighing sensor to ensure that the high-precision weighing sensor 405 does not fail even when deformed by external force; at the same time, it can prevent the high-precision weighing sensor 405 from being damaged by human beings during maintenance.

[0045] like Figure 6 As shown, the medicine mixing and dosing main mechanism 403 is convenient for the quick removal of the rotating large medicine barrel 411. The end of the rotating shaft 415 connected to the rotating large medicine barrel 411 is a hollow disc-shaped structure, and an arc groove 424 is symmetrically opened at one end of the disc. The other end of the disc of the rotating shaft 415 is provided with two threaded holes for installing a quick-release pin 416; and a limit pin 423 is provided on the disc. A step shaft is provided at the bottom of the rotating large medicine barrel 411, and a fan-shaped baffle 422 is symmetrically provided at the end of the step shaft, and a plug hole is symmetrically provided on the fan-shaped baffle 422. During use, first insert the fan-shaped baffle 422 of the bottom step shaft of the rotating large medicine barrel 411 into the arc groove 424 of the rotating shaft 415 disc, then rotate the rotating large medicine barrel 411, and use the limit pin 423 to ensure that the rotating large medicine barrel 411 rotates into place. At this time, the socket on the fan-shaped baffle 422 is completely aligned with the quick-release pin 416. The quick-release pin 416 is manually opened and quickly inserted into the socket to complete the fixation of the rotating large medicine barrel 411.

[0046] The main mechanism 403 for mixing and dosing medicines, and the left and right sides of the front end of the medicine cup placement tray 401 are provided with two groups of grooves with different structural shapes, which can hold small medicine cups of different shapes for medicine distribution. At the same time, a cross-shaped long hole is provided in the middle of each groove. The cross-shaped long hole can cooperate with the weighing tray 406. When starting to work, the medicine cup placement tray 401 comes to the bottom of the transition funnel 409 through the transmission module 402, and the weighing lifting cylinder 414 drives the weighing tray 406 to rise. The L-shaped drag claw of the weighing tray 406 can pass through the cross-shaped long hole to lift the medicine cup in the medicine cup placement tray 401 to the bottom of the transition funnel 409 for medicine distribution; after the medicine distribution is completed, the weighing tray 406 places the medicine cup in the medicine cup placement tray 401 again.

[0047] like Figure 5 As shown, the medicine mixing and quantitative dispensing main mechanism 403, in order to ensure quantitative dispensing of medicines, includes two steps of rough dispensing and fine dispensing. When the transmission module 402 drives the medicine cup to the dispensing station, the weighing and lifting cylinder 414 drives the weighing sensor 405 to lift up, and transfers the medicine cup from the medicine cup placement tray 401 of the transmission module 402 to the weighing tray 406 on the weighing sensor 405, until the weighing and lifting cylinder 414 lifts the medicine cup to the lower edge of the transition funnel 409, and the weighing sensor 405 performs the peeling operation. Then, while the rotating medicine barrel 411 rotates, the revolving motor 412 drives the rotating medicine barrel 411 to pour the medicine at a relatively fast speed until the weighing reading of the weighing sensor 405 is close to the set value. This process is the rough separation stage; then the revolving motor 412 stops rotating, and only the rotating motor 418 rotates at a slow and uniform speed, while the medicine in the rotating medicine barrel 411 continues to rotate and mix, and with the help of inertia and rotational friction, the medicine powder on the edge of the rotating medicine barrel 411 is sent into the medicine cup. When the weighing reading of the weighing sensor 405 differs from the set value by less than 1g, the rotating motor 418 stops rotating to ensure that the residual medicine in the air enters the medicine cup, thereby completing the medicine separation operation. This process is the fine separation stage.

[0048] The present invention provides a rotary medicine mixing and dosing machine, which comprises the following steps:

[0049] 1) Set the selected medicine cup and the amount of medicine to be dispensed through the touch screen;

[0050] 2) The large medicine cup loading and receiving mechanism 1 grabs the large medicine cup in the interlocking transfer window 101 to the top of the medicine mixing and metering medicine dispensing main mechanism 403, adds the medicine into the rotating large medicine barrel 411, and completes the medicine pouring;

[0051] 3) The rotating motor 418 of the medicine mixing and metering main mechanism 403 drives the rotating large medicine barrel 411 to rotate to mix the medicine;

[0052] 4) The empty medicine cup automatic feeding and loading mechanism 3 uses the empty medicine cup automatic loading mechanism 301 to grab the empty medicine cup in the interlocking transfer window 302 to the corresponding station of the medicine cup placement tray 401 of the transmission module 402;

[0053] 5) The transmission module 402 delivers the empty medicine cup to the main mechanism 403 for mixing and dispensing medicine, and the weighing and lifting cylinder 414 drives the weighing sensor 405 to lift the medicine cup 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 delivers the medicine cup to the loading position again, and the empty medicine cup automatic loading mechanism 301 delivers the medicine cup on the transmission module 402 to the transfer window 302; manual workers can directly collect the medicine cup outside the workshop according to production needs.

[0055] 7) After the production is finished, the large medicine cup feeding mechanism 104 drives the large medicine cup to the lower end of the transition funnel 409, recovers all the remaining medicine in the rotating large medicine barrel 411 into the large medicine cup, and returns the large medicine cup with the remaining medicine collected to the transfer window 101.
