Description

Technical Field

[0001] The invention belongs to the field of automation equipment, in particular to an automatic filling device for energetic solid granules. Background Art

[0002] Increasing the packing density of a type of energetic solid propellant has similar significance to using high-energy energetic propellant in increasing the initial velocity of artillery, but increasing the packing density of a type of energetic propellant is easier to operate and has lower costs. Therefore, increasing the power and initial velocity of barreled weapons by increasing the packing density of a type of energetic propellant is more operational.

[0003] Currently, the filling of energetic solid granules is mainly achieved by manual filling. The process is as follows: manually weighing an energetic solid granule according to the specified ratio in the weighing pharmacy and placing it in the relative hopper; manually transferring the weighed energetic solid granule to its filling room; manually placing other items that need to be placed in the medicine box in the medicine box; manually filling the energetic solid granule in the hopper into the medicine box through the funnel; manually shaking the energetic solid granule after filling is completed; manually installing the medicine shell cover; manually placing the packed medicine box on a tray to prepare for subsequent packaging.

[0004] Based on the above process, the current manual method of filling energetic solid pellets has the following disadvantages: 1. Manual operation is labor-intensive and dangerous, and the volatile gases emitted by the energetic solid pellets are harmful to the human body. 2. Manual hopper filling results in the energetic solid pellets having different and random postures within the pill box, resulting in uneven density and low accuracy. 3. Manual filling of energetic solid pellets involves numerous repetitive steps, making the process cumbersome and inefficient. Summary of the Invention

[0011] The filling mechanism is arranged on both sides of the linear vibration feeding mechanism and is used to fill the medicine pellets into the medicine pellet holes of the densely packed mold;

[0012] The track changing mechanism is arranged in front of the densely packed mold. By switching the position of the channel, vibration loading and cylinder push rod feeding are performed in different channels respectively, which is used to realize alternating filling of medicine particles and improve filling efficiency.

[0024] The terms used in the present invention are only for the purpose of illustrating the embodiments of the present invention and are not intended to limit the present invention. Figure 1-5 , some embodiments of the present invention are described in detail.

[0025] The automatic filling equipment for energetic solid medicine particles includes a medicine particle feeding mechanism 1, a mold transfer assembly 2, a close-packed mold 3, a frame 4, a profile cover 5, a dust collector 6, and an electrostatic detector 7. The medicine particle feeding mechanism 1 and the mold transfer assembly 2 are installed on the frame 4. The close-packed mold 3 is installed on the mold transfer assembly 2 to achieve horizontal and vertical movement. The profile cover 5 is used to isolate and protect important components, and at the same time prevent the dust from spreading during the vibration feeding process of the medicine particles. The dust collector 6 is used to remove the dust of the medicine particles in the profile cover 5 to reduce the impact of the medicine particle dust on the environment and the health of the operator. The electrostatic detector 7 is used to detect the static electricity generated by the friction of the medicine particles during the vibration feeding process. When the static electricity value reaches the warning value, it triggers an alarm and reminds that static electricity treatment needs to be carried out immediately. In addition, if Figure 1 As shown, in order to increase the filling amount and production capacity of medicine pellets, this set of equipment is designed with two sets of closely spaced molds 3, which are filled and loaded by the loading mechanism 1.

[0026] Since each set of closely packed molds 3 needs to be loaded with two specifications of granules, two sets of feeding mechanisms 1 and mold transfer components 2 are designed to accommodate the loading of granules of two specifications and realize directional and orderly transportation of granules. The two sets of feeding mechanisms and two sets of mold transfer components 2 are completely consistent in structure and function. The difference lies in the different sizes when adapting to granules of different specifications. Figure 2 As shown, the medicine pellet feeding mechanism 1 mainly includes a vibrating material tray 11 , a linear vibrating feeding mechanism 12 , a track changing mechanism 14 and a filling mechanism 13 .

[0027] The vibrating tray 11 is fixed to the table of the frame 4 and is used to hold energetic solid pellets and convey them to the linear vibrating feeder 12 through vibration. The linear vibrating feeder 12 uses high-frequency, micro-amplitude vibration to move the pellets in a specific direction. The vibration amplitude and frequency can be adjusted by adjusting the vibration device to adjust the conveying speed.

[0028] The linear vibration feeding mechanism 12 is connected to the vibration material tray 11 and the track changing mechanism 14. The linear vibration feeding mechanism 12 mainly includes a linear track 121, a linear vibrator 122, a vibrator mounting plate 123 and a mounting base 124.

[0029] The linear track 121 is fixed above the linear vibrator 122 and is used to transport energetic solid particles. The linear vibrator 122 is used to provide a power source for vibration. The mounting base 124 is fixed on the table of the frame 4. The vibrator mounting plate 123 is fixed on the mounting base 124. The linear vibrator 122 is mounted on the vibrator mounting plate 123.

[0030] The filling mechanism 13 mainly includes a cylinder bracket 131, a cylinder 132 is fixed on the cylinder bracket 131, and the cylinder bracket 131 is installed on the table of the frame 4. In each feeding mechanism 1, a set of filling mechanisms 13 are respectively set up on both sides A and B of the linear track 121 of the linear vibration feeding mechanism 12, which are used to fill the medicine particles into the medicine particle holes of the densely packed mold 3 through the telescopic movement of the cylinder 132.

[0031] The track-changing mechanism 14 primarily comprises a dual-channel platform 141, a photoelectric sensor 142, a slide cylinder 143, a baffle 144, and a cylinder support 145. The photoelectric sensor 142 detects the operating position of the cylinder 132. This means that the pellets can only be fully loaded into the densely packed mold 3 when the cylinder 132 reaches the designated position. The track-changing mechanism 14 switches the positions of channels A and B, performing vibration loading and cylinder push rod feeding in channels A and B, respectively, to achieve alternating loading of pellets and improve loading efficiency.

[0032] The cylinder bracket 145 is fixed on the table surface of the frame 4, the slide cylinder 143 is fixedly installed on the cylinder bracket 145, and the dual-channel platform 141 is fixedly connected to the slide mechanism of the slide cylinder 143, and then the movement of the dual-channel platform 141 is driven by the movement of the slide.

[0033] The blocking piece 144 is fixed on the cylinder bracket 145 and is in the same straight line as the linear track 121 in the linear vibration feeding mechanism 12, and is used to block the medicine pellets on the linear track 121 to prevent the medicine pellets from falling in the non-filling position.

[0034] The dual-channel platform 141 is equipped with two parallel linear channels, Channel A and Channel B. The dual-channel platform 141 is moved by retracting and extending the slide cylinder 142, thereby changing the channel aligned with the linear track 121. When the slide cylinder 142 is extended, Channel A in the dual-channel platform mates with the linear track 121 for loading. At this time, the cylinder 132 on the B side of the linear track 121 aligns with Channel B in the dual-channel platform. When Channel A in the dual-channel platform 141 is filled with pills, the slide cylinder 142 retracts, and the dual-channel platform 141 translates. At this time, the cylinder 132 on the A side of the linear track 121 aligns with the center of Channel A in the dual-channel platform 141. Simultaneously, Channel B in the dual-channel platform 141 mates with the linear track 121 of the linear vibrating feeder 12, allowing further loading to Channel B.

[0035] like Figure 4 As shown, the mold transfer assembly 2 includes a servo linear module 21 and an electric cylinder 22, a weighing sensor 23, and a close-packed mold mounting clamping mechanism 24. The servo linear module 21 is mounted on the table of the frame 4. The electric cylinder 22 is fixedly mounted on the slide of the servo linear module 21. The servo linear module 21 is used to achieve horizontal linear motion of the close-packed mold 3, thereby allowing the close-packed mold 3 to move horizontally between the two groups of medicine pellet feeding mechanisms 1; the electric cylinder 22 is used to achieve vertical linear motion of the close-packed mold 3. The bottom of the weighing sensor 23 is fixed to the slide of the electric cylinder 22, and the top of the weighing sensor 23 is fixed to the close-packed mold mounting clamping mechanism 24, which is used to measure the filling mass of the energetic solid medicine pellets in the close-packed mold 3. The close-packed mold mounting clamping mechanism 24 is used to install the close-packed mold 3.

[0036] The close-packed mold 3 is positioned by three positioning pins 26 in the close-packed mold mounting clamping mechanism 24 and fixed by two quick presses 25 .

[0037] The close-packed mold 3 contains two sizes of hexagonal holes for medicine particles. The large holes are evenly distributed on the outer circle, and the small holes are evenly distributed on the inner circle. These two sizes of holes need to be filled with medicine particles of matching sizes. The medicine particles are evenly filled into the close-packed mold 3.

[0038] The close-packed mold 3 uses hexagonal pellet holes to maximize the mold space utilization and increase the density of the charge.

[0039] The mold transfer assembly 2 moves the closely spaced molds 3 to align each charging hole with the corresponding charging channel to achieve automatic charging of the medicine pellets, and the visual inspection system 8 performs positioning and calibration to ensure filling accuracy.

[0040] When the densely packed mold 3 passes through the mold transfer mechanism 2 and a pill hole is transferred to a designated position, channel A in the dual-channel platform 141, the mold pill hole, and the cylinder 132 on the A side of the linear track 121 are aligned. The cylinder's push rod extends, and the pills are loaded into the pill hole of the densely packed mold 3. While the extended cylinder is loading pills into channel A, channel B is loading normally, and the two processes are carried out in parallel, reducing the waiting time for loading.

[0041] The profile cover 5 is arranged on the periphery of the mold transfer assembly 2, the densely packed mold 3, and the frame 4; the profile cover 5 includes a profile frame and a transparent plate. The profile frame is formed by fixedly connecting the profiles, and the transparent plate is fixed on the profile frame. The profile cover 5 is used to isolate and protect important components, and at the same time prevent dust from spreading during the vibration loading process of the medicine particles.

[0042] Dust collector 6 is an explosion-proof bag-type dust collector system consisting of a dust hood, an air duct system, and a dust collector. The dust hood captures dust-laden gases generated during the vibratory conveying of the medicine pellets, ensuring efficient dust capture. The air duct system transports the dust-laden gases to the dust collection equipment. The dust collector uses filter bags to intercept dust and then uses pulse jets or mechanical vibration to clean it. The entire dust collector is explosion-proof, with anti-static fiber used in the filter bags. The dust collector housing, ducting, and other metal components are fully grounded. The dust collection system's dust hood connects to the interior of the profile housing 5 and removes the medicine pellet dust within the housing, minimizing its impact on the environment and the health of operators.

[0043] The electrostatic detector 7 is an explosion-proof non-contact electrostatic detector. It is based on the principle of electrostatic induction. It senses the surface electric field of the medicine particle powder through an explosion-proof probe and converts it into a potential value. The electrostatic detector integrates an electrostatic potentiometer, a charge sensor and a data acquisition module to monitor the electrostatic parameters of objects on the production line in real time and trigger an alarm. The electrostatic detector 7 is installed inside the profile cover 5 and is used to detect the static electricity generated by friction during the vibration feeding process of the medicine particles. When the static electricity value reaches the warning value, an alarm is triggered to remind you that static electricity removal treatment is required immediately.

[0044] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
