In particular, in the production process of some powder materials, dust is easily generated during material transportation and material filling, which is harmful to the human body and has low production efficiency. This traditional manual packaging method can no longer meet the requirements of production companies. With the development of domestic automated packaging technology, these chemical production companies have gradually begun to use semi-automatic or even fully automatic packaging machines and packaging production lines to replace manual packaging. Automated packaging equipment can be used to achieve a series of workstations such as material weighing, filling, sealing, and post-process palletizing. Among the packaging equipment for powder materials, some flexible packaging bag filling and sealing equipment has achieved a high degree of automation, such as flexible bag packaging machines. In the entire packaging production process, the flexible bag packaging machine basically realizes a fully automatic packaging process, with almost no human intervention, which greatly improves production efficiency, reduces labor costs, and reduces the risk of operating errors and cross-contamination of packaging products.

It is precisely because of these risks that the current situation of difficulty in hiring and recruiting for production enterprises has also been caused. Therefore, it is urgent to develop a set of fully automatic material conveying systems suitable for old workshops for automated packaging production enterprises to solve the material conveying system in workshops with smaller spaces.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] (Example 1)

[0037] like Figures 1 to 5The fully automatic material conveying system shown comprises a mobile silo 1, a soft bag packaging machine 2, an elevator 3, a first conveyor 4, a fixed silo 5, a bin opening mechanism 6 and a second conveyor 7, wherein two elevators 3 are provided and are respectively located on both sides of the soft bag packaging machine 2, and two second conveyors 7 are also provided and are respectively located in the two elevators 3, and the lifting and lowering movement is realized under the action of the elevators 3. A platform fixedly mounted on the soft bag packaging machine 2 is provided between the two elevators 3, and the first conveyor 4, the fixed silo 5 and the bin opening mechanism 6 are all fixedly mounted on the platform, wherein the fixed silo 5 is located below the first conveyor 4 and the discharge port is directly opposite to the feed port of the soft bag packaging machine 2, and the two ends of the first conveyor 4 extend to the two elevators 3 respectively and are connected to the second conveyor 7 after the rise, and the bin opening mechanism 6 is provided on the side of the first conveyor 4. When the mobile silo 1 is loaded with materials, it is placed on one of the second conveyors 7 by a forklift, and after following the elevator 3 to rise, it docks with the first conveyor 4, and then moves horizontally under the action of the first conveyor 4. A liftable material guide assembly 8 is inserted on the top of the fixed silo 5, and a material valve 9 is provided at the discharge port of the mobile silo 1. When the mobile silo 1 moves to the top of the fixed silo 5, the upper end of the material guide assembly 8 faces the discharge port of the mobile silo 5 and is lifted and lowered to dock with the material valve 9. At this time, the opening mechanism 6 is actuated and opens the material valve 9, and the material automatically enters the fixed silo 5 and finally enters the soft bag packaging machine 2 for automatic packaging. When all the materials fall into the fixed silo 5, the mobile silo 5 continues to move to the second conveyor 7 on the other side under the action of the first conveyor 4, and falls under the action of the lifting elevator 3. After being transferred by the forklift, it continues to circulate and circulate, thereby realizing automatic transportation of materials in the narrow and confined space of the old factory building. The overall volume is small, and the space occupied is small, which is suitable for the confined space of the old factory building. The material valve 9 at the discharge port of the mobile silo 1 is opened by the opening mechanism 6, and the material is introduced into the fixed silo 5 by the material guide component 8 to realize the caching of the material, and finally enters the soft bag packaging machine 2 for automatic packaging, which reduces the time of the soft bag packaging machine stopping to wait for manual material transportation, improves production efficiency, and meets the large-scale production needs of the enterprise.

[0038] Specifically, the first conveyor 4 and the second conveyor 7 are both provided with a limit assembly, which includes a limit portion 10 which is respectively arranged around the designated position of the mobile silo 1 and can be raised and lowered, wherein the designated position is the middle of the second conveyor 7 and the first conveyor 4 is located directly above the fixed silo 5. The limit portion 10 adopts a blocking cylinder, so that the mobile silo 1 is lowered in a translational manner and rises when it reaches the designated position, which is used to limit the stop position of the mobile silo 1, thereby ensuring that the mobile silo 1 can stay at the position stably and accurately.

[0039] A mounting plate 11 is horizontally mounted on the top of the fixed silo 5, and an adjusting screw 12 is connected around the bottom of the mounting plate 11 and between the fixed silo 5 and the mounting plate 11 is adjustable along the longitudinal direction through the adjusting screw 12, which is convenient for installation and debugging. Lifting cylinders 13 are fixed symmetrically on both sides of the mounting plate 11, and the piston rods of the lifting cylinders 13 are vertically arranged upward and fixedly connected to the lifting plate 14. The material guide assembly 8 includes an interface flange 8-1 and a material guide pipe 8-2 which are sequentially connected from top to bottom, wherein the interface flange 8-1 is fixedly mounted on the lifting plate 14, and the diameter of the upper port is larger than the diameter of the lower port, so that the materials can be collected and fall into the fixed silo. The material guide pipe 8-2 passes through the mounting plate 11 and is inserted into the fixed silo 5. When the mobile silo 1 is translated into place, the material guide assembly 8 rises and docks with the material valve 9.

[0040] The material valve 9 is a hand wheel clamp type butterfly valve, and the opening mechanism 6 includes a support seat 6-1, an opening cylinder 6-2, a guide rod 6-3, a sliding plate 6-4, an opening motor 6-5 and an opening turntable 6-6. The support seat 6-1 is fixedly mounted on the platform, the opening cylinder 6-2 is fixedly mounted on the top of the support seat 6-1, two guide rods 6-3 are provided and symmetrically arranged on both sides of the opening cylinder 6-2, and the sliding plate 6-4 is connected between the two guide rods 6-3 and fixedly connected to the piston rod end of the opening cylinder to achieve telescopic movement. The opening motor 6-5 is fixedly mounted on the sliding plate 6-4 and moves synchronously with the sliding plate 6-4. The opening turntable 6-6 is coaxially fixedly connected to the output end of the opening motor 6-5 to achieve rotational movement. When the material guide assembly 8 is docked with the material valve 9, the opening turntable 6-6 extends into the handwheel of the handwheel clamp-type butterfly valve, and the material valve 9 is automatically opened and closed through rotational movement, thereby realizing automatic transfer of materials in the mobile silo 1 to the fixed silo 5, and then entering the soft bag packaging machine 6 for automatic packaging.

[0041] In order to avoid material residue, the present embodiment is provided with a pressure plate seat 15 fixedly mounted on the sliding plate 6-4 on the side of the bin opening motor 6-5, and a vibration pressure plate 16 is provided on the top of the pressure plate seat 15. At the same time, an air hammer 17 is fixedly mounted on the side wall of the fixed silo 5 to ensure the rapid and effective flow of materials. In order to improve the vibration effect, the vibration pressure plate 16 of the present embodiment is floatingly mounted on the pressure plate seat 15 through a connecting rod with a spring, thereby ensuring that it fits the side of the mobile silo 1, increasing the vibration contact area, and thus improving the vibration effect.

[0042] In order to realize fully automatic material conveying, in this embodiment, an induction cylinder 18 is fixedly installed on the side of the mounting plate 11. The piston rod of the induction cylinder 18 is vertically arranged upward and an induction plate 19 is fixedly installed at the end. A proximity switch 20 is adjustably installed on the induction plate 19 through an arc groove and a bolt. The material valve 9 is provided with an induction head 21 adapted to the proximity switch 20, so as to automatically detect the opening and closing of the material valve 9 of the mobile silo 1. A material level detection device is fixedly installed on the side wall of the fixed silo 5. The material level detection device includes a full material detection mechanism 22 and a lack of material detection mechanism 23 respectively close to the top and bottom of the fixed silo 5, so as to automatically monitor the material level in the fixed silo 5, so as to realize automatic control of the timing of opening and closing the material valve 9.

[0043] During the production process, the fixed silo 5 detects that the material is running out through its own material level detection device. The operator in the production workshop uses a forklift to transport the mobile silo 1 filled with materials into the elevator 3 and places it on the second conveyor 7 in the elevator. The second conveyor 7 uses its own transmission mechanism to adjust the mobile silo 1 to a specified safe position on the conveyor and ensure that it does not move.

[0044] The lifting elevator 3 starts to rise and slowly lifts the mobile silo 1 to the platform. When it reaches the designated position, the elevator stops and the second conveyor 7 drives the mobile silo 1 to move horizontally to the first conveyor 4 through its own transmission mechanism. After completion, the lifting elevator 3 starts to descend and drives the second conveyor 7 to the ground to receive the next mobile silo 1.

[0045] The first conveyor 4 is connected to the mobile silo 1 and stops at the designated position through its own transmission structure. This position is where the material valve 9 at the outlet of the mobile silo 1 and the material guide assembly 8 at the top of the fixed silo 5 are concentrically docked. At this time, the material guide assembly 8 moves up and is pressed against the flange at the valve port of the material valve 9 to ensure accurate docking without gaps.

[0046] After the docking is completed, the material valve 9 on the mobile silo 1 is opened by the silo opening mechanism 6, the silo door is opened, and the materials flow smoothly into the fixed silo 5. When there is no material, the material valve 9 of the mobile silo 1 closes the silo door. The first conveyor 4 drives the mobile silo 1 that has been emptied of materials to move to the second conveyor 7 on the other side, and after completion, it is ready to receive the next mobile silo 1.

[0047] The second conveyor 7 on the other side is connected to the mobile silo 1. The conveyor adjusts the mobile silo 1 to the designated safe position on the conveyor through its own transmission mechanism and ensures that it does not move. Driven by the elevator 3 on the other side, it descends to the ground, and the forklift forks out the mobile silo 1 to wait for the next work instruction, completing a work cycle.

[0048] In this embodiment, lifting elevators are arranged on both sides of the soft bag packaging machine to lift and lower the mobile silo placed on the first conveyor, and a second conveyor for docking with the two first conveyors is arranged on the top of the soft bag packaging machine, thereby realizing automatic transportation of materials in the narrow and confined space of the old factory building. The overall volume is small, and the space occupied is small, which is suitable for the confined space of the old factory building. The valve at the discharge port of the mobile silo is opened by the silo opening mechanism, and the material is guided into the fixed silo by the material guide component to realize material caching, and finally enter the soft bag packaging machine for automatic packaging, which reduces the time of the soft bag packaging machine stopping to wait for manual material transportation, improves production efficiency, and meets the large-scale production needs of the enterprise.
