Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, and more specifically, to an automatic cleaning system for a storage-type feeder. Furthermore, this invention also relates to a method of using the aforementioned automatic cleaning system for a storage-type feeder. Background Technology

[0002] The sealing strips on the material feeding cart and storage bin of the silo-type feeder equipment leave material residue after passing through. According to production process requirements, to ensure batch weight integrity and processing accuracy, operators are required to promptly clean the remaining material in the material channel after each batch of production. To ensure continuous material conveying, operators need to monitor the remaining material in the storage bin and clean it promptly. Currently, the existing cleaning method involves operators manually sweeping with brooms, requiring quick movements to ensure timely removal of the swept material. Delayed cleaning affects the continuity of material conveying and batch weight accuracy. Furthermore, the operation requires operators to climb, which is inconvenient due to limited space and poses safety hazards such as the risk of falling debris.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] The core of this invention is to provide an automatic cleaning system for a storage-type feeder, which automatically cleans the area to be cleaned, replacing the high-risk and high-intensity manual cleaning work, and greatly improving safety and convenience.

[0061] Another object of the present invention is to provide a method of use for the above-described automatic cleaning system for a storage-type feeder.

[0062] Please refer to Figure 2An automatic cleaning system for a silo-type feeder is disclosed. The silo-type feeder includes a frame 3, a storage bin 1 mounted on the frame 3, a spreading trolley 2 located above the storage bin 1 and moving along the length of the storage bin 1, and a hoist 4 located on one side of the storage bin 1. The automatic cleaning system includes an air supply module 5, an air distribution module 6, and a control module 7. The air supply module 5 is used to provide high-pressure gas. The air distribution module 6 includes a main air path 61, at least three branch paths 62, and several nozzles 63. The air inlet of the main air path 61 is connected to the air supply module 5. The system is connected, with the air inlet of at least three branch lines 62 connected to the main air line 61, and each branch line 62 extending and fixed to different areas to be cleaned by the storage-type feeder. Several nozzles 63 are installed on the corresponding branch lines 62. When high-pressure gas is introduced into the branch lines 62 where the nozzles 63 are located, the nozzles 63 spray airflow into the corresponding areas to be cleaned to remove material residue. The control module 7 includes several control units 701, which are installed on the corresponding main air line 61 and branch lines 62 to control the on / off state of the air lines.

[0063] It should be noted that in this embodiment of the invention, the length direction of the storage bin 1 refers to the direction of material movement. Both the storage bin 1 and the spreading cart 2 are equipped with conveyor belts for conveying materials to the elevator 4. The reciprocating movement direction of the spreading cart 2 is consistent with the feeding direction of the conveyor belt.

[0064] It should be noted that, in this embodiment of the invention, the gas supply module 5 includes a gas supply pipeline, a gas supply valve, a gas supply flow meter, and a gas storage tank. The gas storage tank is connected to the gas supply pipeline. The gas supply valve and the gas supply flow meter are both installed on the gas supply pipeline and are used to monitor the flow rate of the high-pressure gas and control the on / off state of the high-pressure gas. The gas supply pipeline is connected to the main gas line 61 through a quick connector.

[0065] In one embodiment, the air supply module 5 further includes at least two filters, namely a first filter and a second filter, which are installed on an integrated base plate along with the air supply pipeline. The air first passes through the first filter to remove liquid water and solid particles with a diameter greater than 40 micrometers from the compressed air; then it passes through the second filter to further remove fine particles with a diameter greater than 5 micrometers and oil mist. This multi-stage treatment ensures that the compressed air entering the feeder is highly clean and has stable pressure, thus guaranteeing the long-term stability and reliability of the entire automatic cleaning system.

[0066] In addition, in some embodiments of the present invention, several nozzles 63 are duckbill-shaped nozzles, and in some embodiments, the duckbill-shaped nozzles have a motion function. Specifically, they also include a control component, the duckbill-shaped nozzles are connected to the control component, and the control component is used to control the duckbill-shaped nozzles to rotate in at least one direction.

[0067] In one embodiment, the main air passage 61, at least three branch passages 62 and several nozzles 63 are connected by quick-connect couplings to facilitate maintenance or replacement.

[0068] In a specific embodiment of the present invention, high-pressure gas is supplied to the entire system through the gas supply module 5. The gas distribution module 6 includes a main gas path 61, at least three branch paths 62, and several nozzles 63. The inlet end of the main gas path 61 is connected to the gas supply module 5, and the inlet ends of the at least three branch paths 62 are all connected to the main gas path 61 and are respectively extended and fixed to different areas to be cleaned by the storage-type feeder. Several nozzles 63 are respectively installed on the corresponding branch paths 62. When high-pressure gas is introduced into the branch path 62 where several nozzles 63 are located, several nozzles 63 direct the gas towards the main gas path 61. Airflow is sprayed onto the corresponding area to be cleaned to remove material residue. The control module 7 includes several control units 701, which are respectively installed in the corresponding main air passage 61 and branch passage 62 to control the on / off of the air passage. By integrating the feeder body structure with this cleaning system, an online automatic cleaning function is realized, which fundamentally replaces the high-risk and high-intensity manual cleaning operation. The cleaning function can be started at any time to clean the equipment without the need for operators to enter the dangerous area for manual cleaning, which greatly improves safety and convenience.

[0069] Please refer to Figure 2 In some embodiments, the control module 7 further includes several flow regulating valves 702, which are connected in series in the air path where several nozzles 63 are located, for manually or electrically regulating the flow rate of high-pressure gas flowing through the nozzles 63. In other words, the flow regulating valves 702 can be installed in the air path to control the amount of gas ejected from the nozzles 63, thereby controlling the cleaning intensity.

[0070] In one embodiment, the flow regulating valve 702 can also be directly installed at the position of the nozzle 63. Specifically, an air passage is provided between the nozzle 63 and the air passage, and the flow regulating valve 702 is connected in series with the corresponding air passage, so that each nozzle 63 can be adjusted individually.

[0071] In one embodiment, a needle valve-type throttle valve can be used as the flow regulating valve 702. This valve has an adjustment knob; rotating the knob changes the valve core opening, thereby steplessly adjusting the gas flow rate. During installation, the inlet end of the throttle valve is first connected to the vent pipe, and the outlet end is then connected to the nozzle 63, thus achieving personalized fine-tuning of the airflow impact force for each nozzle 63. For example, for lighter tobacco, a smaller flow rate can be adjusted to avoid blowing it away; for clumped materials, a larger flow rate can be adjusted to enhance the cleaning force. This precise control avoids material breakage or dust dispersion caused by excessive airflow, and also prevents incomplete cleaning due to insufficient airflow.

[0072] Please refer to Figure 2 In some embodiments, the control module 7 further includes a controller, and several control units 701 are all electrically controlled valves and are all electrically connected to the controller, used to automatically control the on / off state of the main air passage 61 and the branch passage 62 according to the received production status signal. Several flow regulating valves 702 are all electric flow regulating valves 702 and are all electrically connected to the controller.

[0073] In the above embodiment, the controller has a built-in PLC program to individually control each controller and flow regulating valve 702, achieving precise and independent control of the cleaning area (material carrier 2, both sides of the storage tank, and the rear of the storage tank). This not only allows for flexible arrangement of the cleaning sequence according to process requirements (such as cleaning the rear first, then the sides and material carrier 2), but also enables the activation of only the necessary branch circuits 62 when cleaning is required for non-all areas (such as local cleaning in manual mode), significantly saving compressed air energy consumption.

[0074] Both the material spreading vehicle 2 and the storage box 1 are equipped with conveyor belts. In order to prevent materials from falling outside the conveyor belt during conveying, baffles or curtains are installed on both sides of the conveyor belt to block the materials. However, during the material conveying or spreading process, materials inevitably fall outside the baffles or curtains, resulting in material residue.

[0075] Please refer to Figure 6 In some embodiments, at least three branches 62 include a material paving vehicle cleaning branch 621, which is mounted on the frame 3 and extends above the material paving vehicle 2. The material paving vehicle cleaning branch 621 is provided with at least two nozzles 63 arranged at a preset interval for removing material residue in the side guard strip area on both sides of the material paving vehicle 2.

[0076] In the above embodiment, after the cleaning branch 621 of the paving vehicle is separated from the main air passage 61, it is fixed to the upper edge of the frame 3 or the paving vehicle 2 by means of arrangement, and the nozzle 63 is pointed to the side guard belt area on both sides of the conveyor belt of the paving vehicle 2 below, so as to remove the material residue in the side guard belt area on both sides of the paving vehicle 2.

[0077] In one embodiment, multiple nozzles 63 may be provided in the cleaning branch 621 of the material spreading vehicle, or the cleaning branch 621 of the material spreading vehicle may also include multiple branch pipes arranged perpendicular to the moving direction of the material spreading vehicle 2. Each branch pipe is provided with several nozzles 63. If each branch pipe is connected to the cleaning branch 621 of the material spreading vehicle, several sets of nozzles 63 are evenly distributed in the length direction of the material spreading vehicle 2, which is beneficial to improving the cleaning effect of material residue.

[0078] Please refer to Figure 4In some embodiments, at least three branches 62 further include a first cleaning branch 622 for the storage bin. The first cleaning branch 622 for the storage bin includes at least two parallel internal cleaning branches 6222 arranged along the moving direction of the material spreading vehicle 2 and at least one fixed branch 6221. The air inlets of the at least two internal cleaning branches 6222 are connected to the fixed branch 6221. The air outlets of the at least two internal cleaning branches 6222 extend to the top of the storage bin 1. Each of the at least two internal cleaning branches 6222 is provided with at least two nozzles 63 arranged at a preset interval for removing material residue in the internal area of ​​the storage bin 1.

[0079] In one embodiment, at least two internal cleaning branches 6222 are fixed to the bottom of the material spreading vehicle 2 so that they can move along the length of the storage box 1 with the material spreading vehicle 2. That is, the internal cleaning branches 6222 can move with the material spreading vehicle 2 to clean the entire interior of the storage box 1.

[0080] Please refer to Figure 5 In some embodiments, at least three branches 62 further include at least one second cleaning branch 623 for the storage bin. The second cleaning branch 623 for the storage bin is fixed to the frame 3. The second cleaning branch 623 for the storage bin is arranged perpendicularly to the internal cleaning branch 6222 and extends to the side of the storage bin 1 away from the elevator 4. At least one second cleaning branch 623 for the storage bin is provided with at least two nozzles 63 arranged at a preset interval for removing material residue in the tail area of ​​the storage bin 1.

[0081] By meticulously zoning the areas most prone to material residue, such as the sides and rear of the storage bins, thorough cleaning is ensured. Airflow covers the entire material path, allowing residual material to be systematically removed zone by zone. This reliably guarantees the integrity and weight accuracy of each batch of material, meeting the requirements of refined production management.

[0082] Please refer to Figure 4 In some embodiments, the air distribution module 6 further includes at least one flexible air path 64, with a first quick connector and a second quick connector at each end of the flexible air path 64. The first quick connector is connected to the internal cleaning branch 6222 fixed to the material spreading vehicle 2, and the second quick connector is connected to the fixed branch 6221 fixed to the frame 3.

[0083] In the above embodiments, the high-pressure hose connected by quick-connect fittings constitutes a reliable and durable flexible connection solution. It perfectly adapts to the pulling and bending caused by the reciprocating motion of the material laying vehicle 2, effectively preventing the pipeline from breaking or leaking due to rigid connection. The quick-connect fitting design makes installation and future maintenance (such as hose replacement) extremely simple, without the need for special tools, greatly reducing maintenance difficulty and time cost.

[0084] In one embodiment, the flexible air passage 64 uses a braided high-pressure hose as a flexible pressure-resistant tube.

[0085] In one embodiment, the air distribution module 6 further includes several adjusting components, the number of which is the same as the number of nozzles 63. These adjusting components are used to adjust and lock the airflow direction of the corresponding nozzles 63 within at least one plane. Specifically, the adjusting components may be ball-joint type universal bases. These bases include a fixed seat with internal threads for connecting the cleaning branch 62, a ball-end rod with one end being a ball head that engages with a ball cup in the fixed seat, and the other end having external threads for screwing into the tail interface of the nozzle 63, and a locking nut for adjusting the tightness of the connection between the ball cup and the ball head. After loosening the locking nut, the ball-end rod, along with the nozzle 63 body, can be manually deflected at a certain angle in any direction. Once adjusted to the correct position, the locking nut can be tightened to secure it.

[0086] The ball joint type universal base provides the nozzle 63 with flexible multi-directional angle adjustment capability, which allows the installer to finely adjust the spray angle of the nozzle 63 on site according to the actual residual part of the material (such as the corner of the edge band, the seam), to ensure that the high-speed airflow can act on the residual material most effectively, eliminate cleaning dead corners, and improve the reliability and consistency of cleaning effect.

[0087] A method of use for the above-mentioned automatic cleaning system for a storage-type feeder includes:

[0088] The feeding status of the feeder and the material level in the storage bin 1 are monitored in real time. When the material level in the storage bin 1 drops to a preset value, a tail material cleaning signal is issued. Specifically, a sensor can be installed in the storage bin 1 to detect the remaining material level in the storage bin 1.

[0089] In response to the tail material cleaning signal, the controller controls the control unit 701 located in the second cleaning branch 623 of the storage bin to open for a preset time to remove the material residue at the tail of the storage bin 1. The opening time of the control unit 701 located in the second cleaning branch 623 of the storage bin is 2-4 seconds.

[0090] When it is detected that there is no material in the storage bin 1, the material spreading vehicle 2 moves to the side of the elevator 4 and sends out a cleaning signal for the material spreading vehicle 2 and a cleaning signal for the inside of the storage bin 1.

[0091] In response to the cleaning signal of the material spreading vehicle 2 and the cleaning signal inside the storage box 1, the controller controls the control unit 701 located in the cleaning branch 621 of the material spreading vehicle and the first cleaning branch 622 of the storage box to open, so as to remove material residues in the areas on both sides of the material spreading vehicle 2 and the area inside the storage box 1.

[0092] When the material paving trolley 2 moves to the extreme position near the elevator 4, the controller controls the control unit 701 located in the material paving trolley cleaning branch 621 and the first cleaning branch 622 of the storage box to shut down;

[0093] The material spreading vehicle 2 returns to its initial position, awaiting the next production batch.

[0094] The automatic cleaning system of the storage-type feeder in the above embodiments has at least two modes: an automatic cleaning mode in which the control unit 701 automatically controls the cleaning process based on pre-programmed logic and external signals; and a manual trigger mode in which the control unit 701 responds to a single trigger command from the user and executes a complete preset cleaning process.

[0095] In one embodiment, all piping is laid using the existing steel frame (frame 3) of the feeder as support and secured with standard pipe clamps. Nozzles 63 are directly welded to non-moving or material-prone areas such as the wall panels, bottom beams, or inner walls of the storage bins of the material spreading cart 2. This integrated installation method minimizes the impact on the existing equipment structure and space, maintaining the overall aesthetics and compactness of the equipment. Utilizing the existing frame and cable trays eliminates the need for additional complex mounting brackets or wiring paths, significantly reducing the system's additional costs and installation complexity. This allows the cleaning system to be easily added as a high-efficiency, economical standard module to existing or under-construction feeders of the same type.

[0096] In other words, the key point of this invention is that: high-pressure gas is provided to the entire system through the gas supply module 5, and multiple gas paths are connected to the gas supply module 5. Several nozzles 63 are installed on the gas paths and are respectively extended and fixed to different areas to be cleaned of the storage-type feeder. When high-pressure gas is introduced into the branch 62 where several nozzles 63 are located, several nozzles 63 spray airflow into the corresponding areas to be cleaned to remove material residues. The control module 7 is used to control the on and off of the gas paths. By integrating the feeder body structure with this cleaning system, an online automatic cleaning function is realized, which fundamentally replaces the high-risk and high-intensity manual cleaning operation. Moreover, the cleaning function can be activated at any time to clean the equipment without the need for operators to enter dangerous areas for manual cleaning, which greatly improves safety and convenience.

[0097] In addition to the automatic cleaning system for the storage-type feeder disclosed in the above embodiments, the present invention also provides a method for using the above-mentioned automatic cleaning system for the storage-type feeder. For the structure of other parts of the method, please refer to the prior art, and it will not be described again here.

The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of this invention.
