[0024] Optionally, the rotating assembly includes a circular ring, a bent channel, and an electric telescopic rod.

[0025] The circular ring is arranged in the connection cavity through a rotating shaft. The bent channel is arranged in the circular ring at a ninety-degree angle. The bent part of the bent channel corresponds to the center of the circle of the circular ring. There are two groups of electric telescopic rods, which are symmetrically arranged on the inner side wall of the circular ring.

[0026] The two groups of electric telescopic rods are arranged corresponding to the bent channel.

[0036] The output end of the medicine delivery bottle is arranged towards the pressing body, and the plunger is arranged on the bottle body; one end of the needle tube is arranged on the plunger, and the other end penetrates through the pressing body and is arranged in the middle of the detecting cavity.

[0042] Through the above technical solutions, the liquid medicine is transported into the pressing rod through the conveying pipeline and flows into the bottle body.

[0048] Through the above technical solutions, one electronic device is used, and the telescopic rod that can move flexibly is selected for the rest, thereby reducing the cost of the instrument, and the telescopic member can more stably control the pressing rod to move linearly up and down.

[0049] The present invention provides an automatic medicine filling device for vials, which has the following beneficial effects:

[0050] 1. Through the connection setting of the medicine filling structure, the conveyor belt, and the output belt, the vials are transported into the medicine filling structure. Without stopping the transportation and conveying, the vials can be in a static state during the medicine filling to complete the medicine filling effect, thereby increasing the stability of the vials during the medicine filling.

[0051] 2. Through the cooperation setting between the rotating assembly and the pressing and detecting assembly, the vials can be successively shunted and driven to rotate during the transportation of the vials, so as to drive the vials to rotate to be directly below the pressing and detecting assembly. The pressing bottle presses down close to the inlet of the vial, and the pressing and detecting assembly detects whether the bottle mouth position of the vial can receive the liquid medicine. According to the detection situation, the control valve works to transport the liquid medicine into the vial.

[0052] 3. Through the coordinated setting of the medicine delivery structure, medicine liquid is delivered into the vial. According to the signal detected by the pressing detection component, the signal is transmitted to the corresponding control valve, causing the control valve to open and work for quantitative liquid delivery into the vial body. Subsequently, when the pressing rod is moved, the liquid in the vial body is delivered into the vial. In the vial body where the signal detected by the pressing detection component is not received, the control valve remains in the closed state all the time. Therefore, the medicine liquid will not be delivered into the corresponding vial, effectively reducing the problem of medicine liquid loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific embodiments.

[0062] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "lateral", "longitudinal", "end", "edge", "side wall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0063] The present application proposes an automatic drug filling device for vials, specifically as follows:

[0064] The structure mainly consists of three parts: a conveyor belt 1, an output belt 2, and a drug filling structure 3;

[0065] Reference can be made to Figure 1 , the conveyor belt 1 is used to convey vials into the drug filling structure 3; the output belt 2 is used to output the vials that have been conveyed with drugs in the drug filling structure 3; both the conveyor belt 1 and the output belt 2 are electrically transmitted. The vials are placed on the conveyor belt 1 and conveyed to the drug filling structure 3. After the vials complete the work of receiving the liquid medicine in the drug filling structure 3, they are conveyed from the drug filling structure 3 to the output belt 2.

[0066] Reference can be made to Figure 1 , protective channels 8 are provided on the upper sides of both the conveyor belt 1 and the output belt 2. The protective channels 8 are formed on both side ends of the conveyor belt 1 and the output belt 2 to form a shielding effect, effectively preventing the vials from tipping over; the width formed by the protective channels 8 is adapted to the width of one vial. The width of the conveyor belt 1 can only carry one vial, so when conveying the vials into the drug filling structure 3, the situation of the vials being disorderly can be reduced; among them, the height of the protective channels 8 is the same as the height of the vials.

[0067] Reference can be made to Figure 1 , the drug filling structure 3 is used to quantitatively convey liquid medicine to the vials; the drug filling structure 3 includes a connection cavity 31, a driving component 4, a rotating component 5, a pressing and detecting component 6, and a drug conveying structure 7;

[0068] Reference can be made to Figure 1 , openings 9 are provided on both sides of the connection cavity 31 corresponding to the conveyor belt 1 and the output belt 2. The openings 9 are adapted to the vials, and the vials enter the interior of the connection cavity 31 through the openings;

[0069] Further, the outer periphery of the opening 9 is connected to the protective path 8, and the inner side of the protective path 8 is flush with the inner edge of the opening 9, so that the width of the opening 9 is the same as the width formed by the protective path 8, and only a single vial is supported to be conveyed into the connection cavity 31 each time.

[0070] Reference can be made to Figure 2 , after the vial enters the connection cavity 31 through the conveyor belt 1, it contacts the rotating assembly 5; the rotating assembly 5 includes a circular ring 51, a bending path 52, and an electric telescopic rod 53;

[0071] The circular ring 51 is arranged in the connection cavity 31 through a rotating shaft, and the outer ring of the circular ring 51 is tightly connected to the inner side wall of the connection cavity 31. The circular ring 51 located in the connection cavity 31 can be rotated by the driving assembly 4, so as to drive the bending path 52 arranged on the circular ring 51 to make the same rotational movement;

[0072] Since the output belt 2 and the conveyor belt 1 are symmetrically arranged, the connection angle formed between the two is 180 degrees; in order to facilitate the bending path 52 during rotation, the two fork channels presented by the bending path 52 can contact the matching opening 9 and the pressing detection assembly 6 at the same time, so the bending path 52 is arranged in the circular ring 51 at 90 degrees; when the bending path 52 moves in the connection cavity 31, the two fork channels of the bending path 52 can match two working positions and move simultaneously.

[0073] Reference can be made to Figure 3 , further illustrate the bending path 52. The bending part of the bending path 52 corresponds to the center of the circle of the circular ring 51, and the bending path 52 is arranged in the circular ring 51 in a 90-degree bending form; there are two places where the bending path 52 is connected to the edge end of the circular ring 51, and after the two are connected to the circular ring 51, the connection part is an inlet; except for the two inlets formed by the bending path 52, no other inlets and outlets are opened at the remaining positions of the circular ring 51. Therefore, when the circular ring 51 rotates and the opening 9 is not connected to the inlet, the vial cannot enter the connection cavity 31 through the opening 9.

[0074] Reference can be made to Figure 3 , when the inlet formed by the bending path 52 corresponds to the opening 9, the conveyor belt 1 pushes the vial into the bending path 52. Since the width of the bending path 52 is the same as that of the opening 9, when the vial is conveyed into the bending path 52, it is relatively neat;

[0075] Reference can be made to Figure 4 , the vial will be pushed by the conveyor belt 1 towards the direction of the limiting plate 521 during transportation. When the vial contacts the limiting plate 521 during movement, a chip sensor 522 is arranged in the limiting plate 521 to generate a signal; the signal of the chip sensor 522 is transmitted to the driving motor 41, so that the driving motor 41 drives the driving shaft 42 to rotate, and drives the entire rotating assembly 5 connected to the driving shaft 42.

[0076] For reference Figure 5 When the driving motor 41 drives the rotating assembly 5 to move, the vials are sequentially displaced under the pressing and detecting assembly 6. The pressing body 61 in the pressing and detecting assembly 6 presses down through a small telescopic rod. When the pressing body 61 presses down, the detecting cavity 63 detects whether the top position of the vial is at the center of the detecting cavity 63.

[0077] For reference Figure 6 The detecting cavity 63 is a hollow cylindrical shape that gradually increases from the pressing direction of the pressing body 61. Its internal structure is substantially the same as that of the existing inductor, and is used to sense the circular state of the top of the vial.

[0078] For reference Figure 7 When the detecting cavity 63 senses that there is a vial in the cavity, it transmits a signal to the pressure relief valve 722 and the control valve 731; the pressure relief valve 722 opens, and the pressure in the medicine delivery bottle 71 is discharged from the pressure discharge pipe 721. During the pressure discharge process, the control valve 731 starts to work, so that the delivery pipeline 732 delivers medicine into the medicine delivery bottle 71.

[0079] Further explanation, under the control of the control valve 731 for specific medicine delivery, it needs to be connected to an external main control system, so that the main control system controls the medicine delivery volume of the control valve 731.

[0080] For reference Figures 6 - 7 When the amount of medicine flowing into the medicine delivery bottle 71 through the delivery pipeline 732 reaches the set input value, the main control system closes the control valve 731, so that the delivery pipeline 732 stops the medicine delivery work, and at the same time the pressure relief valve 722 closes.

[0081] When the detecting cavity 63 does not sense that there is a vial in the cavity, it does not send a signal to the corresponding pressure relief valve 722 and control valve 731. Therefore, the pressure relief and medicine delivery work will not start. At this time, the corresponding group of medicine delivery bottles 71 is empty.

[0082] For reference Figures 6 - 7 The medicine delivery bottle 71 is similar in structure to most existing syringes. It is composed of a bottle body 711, a plunger 712 and a needle tube 713. The plunger 712 is connected to the output end of the bottle body 711, and the needle tube 713 is connected to the plunger 712. The plunger 712 can block the liquid in the bottle body 711 from being delivered into the needle tube 713.

[0083] For reference Figure 7, when it is necessary to transport the liquid medicine in the bottle body 711 near the vial, the lifting member 74 is used to control the pressing rod 72 to move downward to push the liquid medicine in the bottle body 711; the liquid medicine flows out of the needle tube 713 with the push and enters the vial. When it is sensed that the top of the vial is not in the detected appearance and direction position, and there is no liquid medicine in the corresponding bottle body 711, the liquid medicine will not flow downward, thereby reducing the waste of liquid medicine.

[0084] for reference Figure 7 , the lifting rod 742 is arranged at the central position of the two bottle bodies 711, and the lifting rod 742 is an electric device; when the lifting rod 742 drives the bottle body 711 to lift and lower, the pressing rod 72 inserted in the bottle bodies 711 on both sides is connected through the top plate 741. In the structural design, only one lifting rod 742 is connected to the top plate 741, and the middle parts of the connections of the other bottle bodies 711 are provided with telescopic members 743 to form a stable connection relationship with the corresponding top plate 741, so as to promote the pressing rod 72 to stably move up and down.

[0085] can be composed of Figure 7 It can be seen that the telescopic member 743 is composed of two rods connected together, which is a common existing socket telescopic structure. Through the movement of the lifting rod 742, the two rods of the telescopic member 743 move linearly relative to each other.

[0086] for reference Figure 7 , a clamping block 611 is provided at the upper end position of the pressing body 61. The clamping block 611 is adapted to the clamping seat 612 provided on the connecting cavity 31. The clamping seat 612 limits the clamping block 611 to limit the position distance of the downward movement of the pressing body 61, reducing the problem of excessive downward pressing amplitude, so as to reduce the deviation situation; at the same time, a balance plate 613 is provided at the lower side end of the pressing body 61, which can make the pressing body 61 more stably connected and arranged on the upper side of the bending path 52.

[0087] for reference Figure 7 , a fixing plate 614 is provided on the pressing body 61. When the fixing plate 614 moves downward with the pressing body 61, it will be inserted into the bearing frame 615, thereby preventing misalignment.

[0088] for reference Figure 7 , the bending path 52 can drive two groups of vials to move along with the driving assembly 4. The number of vials in each group is the same as the number of medicine delivery bottles 71 provided on the pressing and detecting assembly 6. A delivery member 73 is provided on each of the multiple groups of medicine delivery bottles 71 for draining the liquid in the bottle;

[0089] for reference Figure 7, there are also multiple groups of conveying pipelines 732 connected to the medicine infusion bottle 71. To facilitate the subsequent tidiness of the conveying pipelines 732, multiple connected conveying pipelines 732 are connected together in a single pipeline and passed through the protection cavity 10, and then exit from the other end of the protection cavity 10; the protection cavity 10 serves as a fixed fulcrum for the multiple conveying pipelines 732, making it look more concise.

[0090] For reference Figure 1 , one end of the conveying pipeline 732 that exits the protection cavity 10 is fixedly arranged on the fixed shaft 11, and the liquid medicine storage tube is connected to the conveying pipeline 732 on the fixed shaft 11 through a pipeline to convey the liquid medicine into the device.

[0091] For reference Figures 2 - 3 , after the vial in the bending path 52 is input with liquid medicine, it rotates again to correspond to the opening 9 on one side of the output belt 2, and then the electric telescopic rod 53 on the same side is driven to work, pushing the vial to move onto the output belt 2. Among them, the arc-shaped plate 531 arranged on one side of the electric telescopic rod 53 is made of anti-slip material, making it more stable when pushing the vial; thus repeating the process of automatic medicine loading.

[0092] Further, the specific rotation work of the circular ring 51 is described. The two branch channels formed by bending the bending path 52 are sensed by the chip sensor 522 to send signals to the driving motor 41 for the vial to rotate and move, and the moving distance range is 90 degrees. Under the limited movement of 90 degrees, the vial in the bending path 52 will be located below the pressing and detecting component 6; because there are two branch channels in the bending path 52 and the other branch channel moves the same as the front branch channel, when one end of a bending path 52 is connected to the opening 9 at the output belt 2.

[0093] During all the above power-on periods, debugging can be carried out through a general system, and the movement process between each device can be determined according to precise time control; it can also be controlled by setting multiple groups of sensors for signal transmission; since the switch is a common means during system control, this application will not elaborate too much.

[0094] In the present invention, the working steps of the device are as follows:

[0095] 1. First, place the vial on the conveyor belt 1 and convey it into the medicine loading structure 3. The vial enters the bending path 52 in the connection cavity 31 through the opening 9. When the vial touches the limit plate 521, the chip sensor 522 sends a signal to the driving motor 41, and the driving motor 41 drives the bending path 52 to rotate, so that one end of the bending path 52 is located below the pressing and detecting component 6, and the other end is displaced with the rotation to the opening 9 on the conveyor belt 1. Along with the conveyance of the conveyor belt 1, the vial is conveyed into the bending path 52 again;

[0096] 2. Secondly, the pressing detection component 6 starts to work when the driving motor 41 stops driving. It achieves the effect of pressing down through the small telescopic rod, so that the detection cavity 63 under the pressing body 61 moves downward to detect whether the circular structure at the top of the vial can be detected, and transmits the detection information to the control valve 731 and the pressure relief valve 722;

[0097] 3. Then, when no signal is received, the control valve 731 does not start to work; when a signal is received, the control valve 731 and the pressure relief valve 722 start to work and deliver the liquid medicine into the bottle body 711. After the liquid medicine delivery stops, the lifting member 74 controls the pressing rod 72 to perform the pressing and lifting work to deliver the liquid medicine from the bottle body 711 into the vial;

[0098] 4. Finally, the process of delivering the liquid medicine has been debugged multiple times to control the time range to be less than the time for delivering the vial into the bending channel 52. Therefore, when the vial contacts the chip sensor 522 and causes the bending channel 52 to rotate again, the vial that needs to receive the liquid medicine has completed the receiving work, and again according to the rotation, the opening 9 on the side of the output belt 2 of the bending channel 52 carrying the medicine-bearing vial is located. The electric telescopic rod 53 starts and pushes the vial to exit from the opening 9 of the output belt 2 and is located on the output belt 2; the pushing time of the electric telescopic rod 53 is greater than the time for receiving the liquid medicine. After multiple tests, the time is controlled so that the vial will complete the liquid medicine receiving work before the electric telescopic rod 53 resets; when the electric telescopic rod 53 resets, the driving motor 41 rotates again, and each driving operation of the driving motor 41 is 90 degrees; thus, the above steps are repeated multiple times to form the liquid medicine delivery process of the vial.

[0099] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope claimed by the present invention. The scope claimed by the present invention is defined by the appended claims and their equivalents.
