Description

Technical Field

[0001] This utility model relates to the field of ammunition production equipment technology, specifically to an automated production line for rapid and accurate weighing and dispensing of ammunition. Background Technology

[0002] Currently, some munitions have high requirements for the amount of propellant they contain. Therefore, manual weighing is required in the propellant distribution process before filling to control the accuracy of the amount of propellant. Specifically, a copper spoon is used to scoop the propellant from the propellant tray, and the process amount is weighed one by one using an explosion-proof electronic scale. Propellant that meets the requirements is poured into the corresponding loading box for subsequent filling processes, while propellant that does not meet the requirements is poured back into the propellant tray and scooped again. The accuracy of manual weighing varies greatly depending on the skill level of the personnel, the consistency of the weight of the propellant is poor, and the efficiency is low, which cannot meet the current equipment quality level and equipment supply capabilities.

Detailed Implementation

[0017] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example 1

[0018] like Figure 1 and Figure 2 As shown, Figure 1 This is a structural view of the automated production line for rapid and accurate weighing and dispensing of medicines. Figure 2 This is a structural layout diagram of the frame.

[0019] The automated production line for rapid and accurate weighing and dispensing of medicines according to this utility model includes a medicine cup feeding unit 1, a medicine loading bin 2, a volume-fixing coarse dispensing unit 3, a precision replenishment unit 4, and a weighing unit 5. The medicine cup feeding unit 1, the medicine loading bin 2, the volume-fixing coarse dispensing unit 3, the precision replenishment unit 4, and the weighing unit 5 are all fixedly mounted on a frame 6 to achieve relative positional stability. The medicine loading bin 2, the volume-fixing coarse dispensing unit 3, the precision replenishment unit 4, the weighing unit 5, and the medicine cup feeding unit 1... The system is arranged from top to bottom. The dispensing robot 7 pours medicine powder into the medicine hopper 2, and then replenishes medicine powder to both the volume-fixing coarse distribution section 3 and the precision medicine replenishment section 4 through the medicine hopper 2. The initial volume-fixing medicine replenishment of the volume-fixing coarse distribution section 3 and the vibration-based fine medicine replenishment of the precision medicine replenishment section 4 replenish the medicine powder to the weighing section 5 respectively. After weighing and quantifying the medicine powder in the weighing section 5, the medicine powder is filled into the medicine cup located on the medicine cup feeding section 1, thereby achieving precise quantification of medicine powder in the medicine cup.

[0020] This invention, by setting up the volume-fixing coarse distribution section 3, the precision replenishment section 4, and the weighing section 5, designs the powder feeding process in the dispensing process into two stages: rapid feeding and precise feeding. First, the volume-fixing coarse distribution section 3 uses initial weighing to control the feeding amount to quickly reach about 95% of the target amount of medicine. Then, the precision replenishment section 4 performs subsequent precise feeding to keep the weighing within the error range, thereby achieving rapid and accurate weighing and greatly improving the dispensing efficiency and the accuracy of the dispensing weight. Example 2

[0021] like Figure 3 and Figure 4 As shown, Figure 3 This is a three-dimensional structural view of the coarse volume division; Figure 4 This is a schematic diagram of the internal structure of the fixed-volume coarse section.

[0022] The volumetric coarse dispensing section 3 includes an upper plate 31, a lower plate 32, a dispensing plate 33, a coarse dispensing mounting frame 34, and a replenishing cylinder 35. The upper plate 31, the lower plate 32, and the replenishing cylinder 35 are fixedly mounted on the coarse dispensing mounting frame 34, which is connected to the frame 6. The dispensing plate 33 is disposed between the upper plate 31 and the lower plate 32, and the telescopic rod of the replenishing cylinder 35 is fixedly connected to the dispensing plate 33. The upper plate 31, the lower plate 32, and the dispensing plate 33 are all arranged in parallel, and the upper surface of the dispensing plate 33 is attached to the bottom surface of the upper plate 31. The lower surface of the metering plate 33 is attached to the top surface of the lower plate 32. The metering plate 33 is provided with a metering hole 38, which is vertically through. The upper plate 31 is provided with a feeding hole 39, and the lower plate 32 is provided with a leakage hole 40. The drug replenishing cylinder 35 drives the metering plate 33 to move linearly back and forth between the upper plate 31 and the lower plate 32, so that the metering hole 38 is connected to the feeding hole 39 and the leakage hole 40 respectively. The feeding hole 39 is connected to the drug loading bin 2, and the leakage hole 40 is connected to the weighing part 5.

[0023] Preferably, the distance between the feeding hole 39 and the leakage hole 40 is greater than the diameter of the metering hole 38, so as to avoid the feeding hole 39 and the leakage hole 40 being connected to the metering hole 38 at the same time, thus ensuring the accuracy of volume determination.

[0024] The powder enters the replenishment hole from the feeding hopper 2. When the metering hole 38 moves to connect with the replenishment hole 39, the bottom of the metering hole 38 is closed by the action of the lower plate 32, and only the upper end of the metering hole 38 is open. The powder can smoothly enter the metering hole 38 through the replenishment hole 39 and accumulate. After a certain period of time, it moves through the metering hole 38 to the discharge hole 40. During this process, the top of the metering hole 38 is closed by the action of the upper plate 31, so that the metering hole 38 forms a constant-volume sealed space. In this space, the weight of the powder is kept within a certain range. When it moves to connect with the discharge hole 40, the top of the metering hole 38 is closed by the action of the upper plate 31, and only the lower end of the metering hole 38 is open. The powder in the metering hole 38 can smoothly flow into the discharge hole 40 under its own weight and then into the weighing part 5.

[0025] Preferably, the top of the upper plate 31 is provided with a connecting block 36, and a replenishing chamber is provided inside the connecting block 36. The replenishing chamber is configured with a funnel-shaped structure. The replenishing chamber and the replenishing hole are coaxially arranged. The medicine loading bin 2 is fixedly connected to the upper plate 31 through the connecting block 36. The cross-sectional diameter of the replenishing chamber decreases from top to bottom, thereby facilitating the replenishment of medicine powder from the medicine loading bin 2 to the replenishing hole.

[0026] Generally, the bottom of the lower plate 32 is provided with a material leakage pipe 37. The material leakage chamber in the material leakage pipe 37 is coaxially arranged with the material leakage hole 40. The material leakage pipe 37 is arranged between the lower plate 32 and the weighing part 5 to avoid airflow and other factors affecting the directional flow of the powder from the material leakage hole 40 to the weighing part 5. Example 3

[0027] like Figure 5 and Figure 6 As shown, Figure 5 This is a three-dimensional structural view of the precision medicine replenishment unit; Figure 6 This is a front view of the structure of the precision medicine replenishment unit.

[0028] The precision medicine replenishment unit 4 includes a medicine storage chamber 41, a vibration frame 42, and a medicine delivery trough 43. The medicine storage chamber 41 is fixedly mounted on the vibration frame 42. The vibration frame 42 is connected to the frame 6 via a column 45. A vibrating medicine delivery cylinder 44 is mounted on the vibration frame 42. One end of the medicine delivery trough 43 is connected to the medicine storage chamber 41, and the other end is located corresponding to the weighing unit 5. The upper end of the medicine storage chamber 41 is open to communicate with the medicine loading chamber 2. The vibrating medicine delivery cylinder 44 drives the vibration frame 42 to vibrate so that the medicine powder in the medicine storage chamber 41 flows slowly to the weighing unit 5 via the medicine delivery trough 43.

[0029] Specifically, the medicine delivery trough 43 includes a bottom plate and two limiting side plates. The bottom plate and the limiting side plates extend in a straight line in the same direction. The bottom plate is V-shaped, and the two limiting side plates are symmetrically arranged at both ends of the bottom plate. The V-shaped bottom plate can control the flow of medicine powder from the end of the medicine delivery trough 43 to the weighing part 5 in a directional small flow rate. The limiting side plates prevent the medicine powder from shaking and escaping due to vibration.

[0030] Preferably, a feeding port is provided at the connection between the medicine storage chamber 41 and the medicine delivery trough 43. A detachable insert plate 46 is provided on the feeding port. By adjusting the position of the insert plate 46 or by using insert plates 46 of different sizes, the opening size of the feeding port can be adjusted, thereby controlling the flow rate of medicine powder flowing into the medicine delivery trough 43.

[0031] The vibrating frame 42 includes an upper support 421, a lower support 422, and an elastic connecting plate 423. The upper support 421 is fixedly installed at the bottom of the medicine storage chamber 41, and the lower support 422 is fixedly connected to the column 45. A vibration gap is provided between the upper support 421 and the lower support 422. The upper support 421 and the lower support 422 are elastically connected through the elastic connecting plate 423. The vibrating medicine delivery cylinder 44 is fixedly installed on the lower support 422. The vibration of the vibrating medicine delivery cylinder 44 vibrates the lower support 422 and transmits the vibration to the upper support 421 through the elastic connecting plate 423. At the same time, the vibration gap also facilitates the small-angle tilting of the upper support 421, so that the medicine delivery trough 43 and the medicine storage chamber 41 are tilted towards the weighing part 5 with a gradually decreasing overall height, thereby realizing the slow movement of the medicine powder to the weighing part 5 under vibration. Example 4

[0032] like Figure 7 and Figure 8 As shown, Figure 7 This is a three-dimensional structural view of the weighing unit in its tilted state; Figure 8 This is a top view of the structure of the weighing unit in its tilted state.

[0033] The weighing unit 5 includes a weighing box 51, a weighing frame 52, a weighing sensor 53, a medicine funnel 54, and a rotary cylinder 55. The weighing sensor 53 is supported and connected to the weighing box 51 below it via the weighing frame 52. The weighing sensor 53 monitors the weight of the powder in the weighing box 51 in real time. The volume-fixing coarse distribution section 3 and the precise replenishment section 4 are both set corresponding to the weighing box 51 to replenish the powder in the weighing box 51. The rotary cylinder 55 drives the weighing box 51 to rotate. The top opening of the medicine funnel 54 is located on one side of the weighing box 51. When the powder in the weighing box 51 reaches a suitable weight, the rotary cylinder 55 rotates the weighing box 51, pouring the powder into the medicine funnel 54, which then fills the medicine cup located below the medicine funnel 54 through the filling port at the bottom of the medicine funnel 54.

[0034] Specifically, the weighing frame 52 is configured as a U-shaped plate, and both ends of the weighing frame 52 are provided with upward-facing connecting grooves. The two ends of the medicine weighing box 51 are respectively provided with a first connecting shaft 511 and a second connecting shaft 512. The first connecting shaft 511 and the second connecting shaft 512 are coaxially arranged, and the first connecting shaft 511 and the second connecting shaft 512 are respectively arranged in the two connecting grooves, thereby ensuring that the medicine weighing box 51 can rotate freely around the axis of the first connecting shaft 511 and the second connecting shaft 512. At the same time, the weighing frame 52 and the medicine weighing box 51 can move up and down to a certain extent when the weight of the medicine weighing box 51 changes, ensuring the effective transmission of the weight of the medicine weighing box 51 to the weighing sensor 53.

[0035] Generally, a rotating shaft 513 is vertically arranged at the end of the second connecting shaft 512, and a rotating groove 551 is provided on the rotating rod of the rotating cylinder 55. The rotating groove 551 is perpendicular to the rotating rod of the rotating cylinder 55 and passes through it. The rotating shaft 513 is arranged in the rotating groove 551. When the weighing box 51 is in the weighing state, both the rotating shaft 513 and the rotating groove 551 are vertically arranged. The rotating shaft 513 can move freely vertically in the rotating groove 551. The rotating groove 551 has no support contact with the rotating shaft 513, thereby avoiding the influence of the rotating cylinder 55 on the weighing sensor 53. When the weighing box 51 is tilted, the rotating groove 551 rotates, driving the rotating shaft 513 to rotate, thereby realizing the operation of pouring medicine from the weighing box 51 to the medicine funnel 54.

[0036] Preferably, the weighing unit 5 further includes an adjusting guide rail 56, an adjusting cylinder 57, and a packing plate 58. The adjusting guide rail 56 and the adjusting cylinder 57 are both fixedly mounted on the packing plate 58. The adjusting cylinder 57 drives the adjusting slide on the adjusting guide rail 56 to move linearly. The weighing box 51, the weighing frame 52, the weighing sensor 53, the medicine funnel 54, and the rotary cylinder 55 are all mounted on the adjusting slide. The packing plate 58 is provided with a dispensing hole and a discarding hole. The packing port at the bottom of the medicine funnel 54 is respectively positioned corresponding to the dispensing hole and the discarding hole under the action of the adjusting cylinder 57.

[0037] The frame 6 is also equipped with a residual medicine collection bin 8. The bottom of the discard hole is connected to the residual medicine collection bin 8 through a residual medicine pipe. The bottom of the dispensing hole is equipped with a dispensing pipe, which is located directly above the medicine cup feeding part 1. The medicine cup feeding part 1 is generally configured as a conventional fixed-point conveyor structure such as a belt conveyor or chain conveyor.

[0038] When the weighing sensor 53 detects that the powder in the weighing box 51 is within the normal error range, the adjusting cylinder 57 moves the adjusting slide to align the filling port at the bottom of the hopper 54 with the dispensing hole. Then, the rotating cylinder 55 tilts the weighing box 51 to pour out the powder, thus filling the medicine cup on the medicine cup feeding section 1 with the appropriate weight of powder through the hopper 54. When the weighing sensor 53 detects that the powder in the weighing box 51 is overweight, the adjusting cylinder 57 moves the adjusting slide to align the filling port at the bottom of the hopper 54 with the discard hole. Then, the rotating cylinder 55 tilts the weighing box 51 to pour out the powder, thus pouring the unqualified powder into the residual medicine collection bin 8 for retention. If the weighing sensor 53 detects that the powder in the weighing box 51 is underweight, the powder can still be replenished through the precision replenishment section 4.

[0039] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
