[0002] This application claims priority to Chinese patent application No. 202210566857.4, filed on May 24, 2022. The full text of the aforementioned patent application is incorporated herein by reference and forms part of this specification. Technical Field

[0003] This invention relates to the field of container manufacturing technology, specifically to a container assembly line cleaning system and cleaning method. Background Technology

[0004] Currently, the entire container manufacturing industry basically handles the iron / wood shavings generated after drilling containers by manually entering the container and using an air compressor or other handheld device to generate compressed gas to blow the iron / wood shavings out of the container. This method of handling iron / wood shavings causes dust to fly inside and outside the container, resulting in a very poor working environment in the vicinity. It is not only environmentally unfriendly and inefficient, but also makes it easy for operators and workers in the surrounding work areas to inhale dust.

[0005] Furthermore, patent publication number CN213968153U discloses a drilling debris collection system for containers, including a mobile cleaning device. This device comprises a main body, a cleaning brush, a dust cover, a suction assembly, a collection box, and rollers. The mobile cleaning device moves across the container floor to clean drilling debris (mainly iron and wood shavings), replacing manual cleaning of the debris generated after drilling, reducing environmental pollution, and avoiding harm to the health of operators. However, after collecting a certain amount of drilling debris, the mobile cleaning device needs to travel to a designated location for centralized disposal, wasting a significant amount of time, and it cannot separate and recycle the iron and wood shavings within the drilling debris. Summary of the Invention

[0006] To overcome the problems in existing container drilling debris cleaning and collection systems, where mobile cleaning devices need to travel to a designated location for centralized disposal after collecting a certain amount of drilling debris, which wastes a lot of time and makes it impossible to separate and recycle iron and wood shavings from the drilling debris, this invention provides a container assembly line cleaning system and cleaning method.

[0014] Furthermore, the left and right sides of the trolley body are provided with box-entry guide roller assemblies.

[0015] Furthermore, an anti-collision spring bar is provided on the front side of the vehicle body.

[0016] Furthermore, a sensor for sensing the end of the container is provided on the front side of the trolley body, and the sensor is covered by a protective cover, with an opening on the front side of the protective cover for the sensor to sense.

[0017] Furthermore, the ash collection hopper assembly includes an ash collection hopper, the bottom of which is provided with a sliding ash discharge opening and closing plate, and the rear side of the ash collection hopper is provided with an ash discharge telescopic cylinder. The telescopic rod of the ash discharge telescopic cylinder is connected to the ash discharge opening and closing plate, thereby driving the ash discharge opening and closing plate to slide back and forth.

[0018] According to the present invention described above, a spiral lifting conveyor bucket is provided at the rear bottom of the trolley parking platform, the feed end of the iron / wood shaving spiral elevator extends into the spiral lifting conveyor bucket, and the discharge end of the iron / wood shaving spiral elevator is located above the feed end of the iron / wood shaving separator.

[0019] On the other hand, the present invention provides a container assembly line cleaning method, applied to the above-mentioned container assembly line cleaning system, comprising:

[0020] Step S1: The cleaning cart is parked on the cart parking platform to wait for the container to arrive;

[0021] Step S2: The container is moved to a designated position in front of the trolley parking platform;

[0022] Step S3: The cleaning trolley enters the container along the trolley parking platform to clean and collect the iron and wood shavings inside the container;

[0023] Step S4: After cleaning is completed, the cleaning trolley returns to the designated position of the trolley parking platform and releases the collected iron and wood shavings into the spiral lifting conveyor bucket at the bottom rear of the trolley parking platform, and then waits for the next container to be cleaned.

[0024] Step S5: When the spiral conveyor bucket is full of iron shavings and wood shavings, the iron shavings / wood shavings spiral elevator lifts the iron shavings and wood shavings in the spiral conveyor bucket into the iron shavings / wood shavings separator;

[0025] Step S6: The iron shavings / wood shavings separator separates the iron shavings and wood shavings, and loads them into different woven bags in two directions.

[0026] According to the present invention based on the above scheme, step S3 specifically includes:

[0027] Step S31: The sweeping trolley starts the front and rear disc brush assemblies and enters the container along the trolley parking platform;

[0028] Step S32: The front disc brush assembly and the rear disc brush assembly sweep the iron shavings and wood shavings to the herringbone roller brush assembly of the sweeping trolley, and as the sweeping trolley moves forward, they are swept into the dust collection hopper assembly of the sweeping trolley.

[0029] Step S33: When the cleaning trolley reaches the end of the container, it lowers the suction / rake / blow assembly in front and repeatedly moves backward and forward a distance to clean up the iron and wood shavings in the blind spot at the front.

[0030] Step S34: The cleaning trolley exits the container, and during the retreat, the suction / rake / blow assembly cleans up the remaining iron and wood shavings by rake and suction.

[0031] According to the above-described solution, the beneficial effects of this invention are as follows:

[0032] 1. The container assembly line cleaning system provided by the present invention can be connected to the container assembly line to realize the automated cleaning of iron and wood shavings generated after drilling the container.

[0055] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0056] It should be noted that the terms "set," "connect," "fix," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components, unless otherwise explicitly defined. The terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," and "outer" indicate the orientation or position based on the orientation or position shown in the accompanying drawings, and are only for ease of description and should not be construed as limiting the technical solution.

[0057] Please see Figure 1 This embodiment provides a container assembly line cleaning system, including a cleaning trolley 1, a trolley parking platform 2, a metal / wood shavings screw conveyor 3, and a metal / wood shavings separator 4. The trolley parking platform 2 is located at the rear of the container assembly line and connects to it. The cleaning trolley 1 is parked on the trolley parking platform 2 and can enter the container 7 along the platform to clean and collect metal and wood shavings inside. The metal / wood shavings screw conveyor 3 is located between the trolley parking platform 2 and the metal / wood shavings separator 4, lifting the collected metal and wood shavings into the separator 4. A metal shavings woven bag 5 is provided on the metal shavings outlet side of the separator 4, and a wood shavings woven bag 6 is provided on the wood shavings outlet side. After separating the metal and wood shavings, the separator 4 loads the metal shavings into the metal shavings woven bag 5 and the wood shavings into the wood shavings woven bag 6.

[0058] Please see Figure 2 , Figure 3In this embodiment, the sweeping trolley 1 includes a trolley body 101. From front to back, the bottom of the trolley body 101 is sequentially equipped with a suction / rake / blow assembly 102, a front disc brush assembly 103, a rear disc brush assembly 104, a herringbone roller brush assembly 105, and a dust collection hopper assembly 106. The front disc brush assembly 103 includes two front disc brushes 1031 respectively positioned on the left and right sides in front of the herringbone roller brush assembly 105. The rear disc brush assembly 104 includes rear disc brushes 1041 positioned on the left and right sides in front of the front disc brush assembly 103. The suction / rake / blow assembly 102, front disc brush assembly 103, rear disc brush assembly 104, and herringbone roller brush assembly 105 form an inverted triangular area 107. The suction / rake / blow assembly 102 is connected to the trolley body 101 via a suction / rake / blow assembly retraction cylinder 108. As the sweeper 1 enters the container 7, the front disc brush assembly 103, the rear disc brush assembly 104, and the herringbone roller brush assembly 105 are activated. The front disc brush assembly 103 and the rear disc brush assembly 104 sweep the iron and wood shavings to the herringbone roller brush assembly 105, and as the sweeper 1 moves forward, they are rolled into the dust collection hopper assembly 106 of the sweeper 1.

[0059] The suction / rake / blow assembly 102 is mainly used to clean the blind spots and extreme ends of the container 7, removing iron filings and wood shavings. Before the cleaning trolley 1 reaches the end of the container 7, the suction / rake / blow assembly 102 is in a raised state. When the cleaning trolley 1 reaches the end of the container 7, since the inverted triangular area 107 is a cleaning blind spot, the suction / rake / blow assembly 102 needs to be lowered by the suction / rake / blow assembly retraction cylinder 108, and then it moves back about 2 meters to rake the iron filings and wood shavings in the cleaning blind spot to about 2 meters inside the container 7. At this time, the cleaning trolley 1 continues to move forward and throws the rake iron filings and wood shavings into the dust collection hopper assembly 106 through the front disc brush assembly 103, the rear disc brush assembly 104 and the herringbone roller brush assembly 105.

[0060] Please see Figures 4 to 6 The suction / rake / blow assembly 102 includes a blowing pipe 1021, a suction pipe 1022, and a rake assembly arranged sequentially from front to back. The top of the blowing pipe 1021 is provided with several evenly distributed compressed air inlets 10211, and the bottom of the blowing pipe 1021 is provided with a row of blowing holes 10212 (such as 200 0.8 mm blowing holes 10212). After compressed air is introduced into the compressed air inlets 10211, it is blown out through the row of blowing holes 10212 at the bottom to form a blowing air knife, thereby blowing out iron pins and wood shavings in the blind area and extreme end of the box. The top of the suction pipe 1022 is provided with several suction inlets 10221, and the bottom of the suction pipe 1022 is provided with a suction port 10222. The suction inlets 10221 are connected to the dust suction fan of the sweeping cart 1. After the dust suction fan is started, the small particles that have not been raken clean are sucked up through the suction port 10222.

[0061] Please see Figures 4 to 6In a real-time example, the shaving assembly includes two rows of spaced-apart shaving brushes 1023. The two rows of shaving brushes 1023 are fixed to the suction pipe 1022 via a connecting frame 10231. The two rows of shaving brushes 1023 are mainly used to rake iron filings and wood shavings in the end blind area to the area that can be cleaned by the front disc brush assembly 103, the rear disc brush assembly 104, and the herringbone roller brush assembly 105. When the cleaning trolley 1 exits the container 7, it can also rake a very small amount of iron filings and wood shavings that have not been cleaned to the outside of the container 7.

[0062] Please see Figure 7 In another real-time example, the ash-removing assembly includes an ash-removing roller brush 1024. The brush bristles of the ash-removing roller brush 1024 are evenly arranged in a herringbone spiral. The ash-removing roller brush 1024 is driven by a motor, chain, or sprocket. This application is not limited in this respect; it is sufficient to achieve the goal of driving the ash-removing roller brush 1024 to rotate. Bearing seats 10241 are provided on the left and right sides of the ash-removing roller brush 1024, which enable the ash-removing roller brush 1024 to be installed behind the ash-suction pipe 1022.

[0063] Please see Figures 2 to 6 In this embodiment, the fixed end of the suction / rake / blow assembly retractable cylinder 108 is hinged to the trolley body 101, and the telescopic end of the suction / rake / blow assembly retractable cylinder 108 is hinged to the middle of the suction / rake / blow assembly 102. Hinged brackets 109 are provided on both the left and right sides of the suction / rake / blow assembly 102. The hinged brackets 109 include a first hinge bar 1091 and a second hinge bar 1092. One end of the first hinge bar 1091 is fixed to the suction / rake / blow assembly 102, and the other end of the first hinge bar 1091 is hinged to one end of the second hinge bar 1092. The other end of the second hinge bar 1092 is fixed to the trolley body 101. With the above configuration, the suction / rake / blow assembly retraction cylinder 108 can make an arc motion when lowering the suction / rake / blow assembly 102. When the suction / rake / blow assembly 102 makes an arc motion, it can blow the iron pins and wood shavings in the blind zone and extreme end of the box backward, and the structure is stable.

[0064] Please see Figure 2 , Figure 3 , Figure 8In this embodiment, the left and right sides of the trolley body 101 are provided with inlet guide roller assemblies 110. A row of guide rollers 1101 is provided on the outer side of the inlet guide roller assembly 110. Guide roller telescopic cylinders 1102 are provided at both ends of the inner side of the inlet guide roller assembly 110. The guide roller telescopic cylinders 1102 are fixed to the trolley body 101. The telescopic end of the guide roller telescopic cylinder 1102 is fixed to the inlet guide roller assembly 110. The distance between the inlet guide roller assemblies 110 on the left and right sides of the trolley body 101 can be adjusted by the guide roller telescopic cylinders 1102 so that the distance between the inlet guide roller assemblies 110 on both sides matches the width of the container 7. Thus, the cleaning trolley 1 can be guided into the container 7 by the inlet guide roller assemblies 110 on both sides.

[0065] Please see Figure 2 , Figure 3 , Figure 8 In this embodiment, a collision-resistant elastic bar 111 is provided on the front side of the trolley body 101 to protect the suction / rake / blow assembly 102 and prevent the suction / rake / blow assembly 102 from colliding with the container wall of the container 7 when the cleaning trolley 1 reaches the end of the container 7.

[0066] Please see Figure 2 In this embodiment, a sensor is provided on the front side of the trolley body 101. The sensor is used to sense whether the cleaning trolley 1 has reached the end of the container 7. At the same time, there is an outer cover 7 for the sensor. The front side of the protective cover 112 is provided with an opening for the sensor to sense. The protective cover 112 serves to protect the sensor.

[0067] Please see Figures 9 to 11 In this embodiment, the ash hopper assembly 106 includes an ash hopper 1061. A sliding ash discharge opening and closing plate 1062 is provided at the bottom of the ash hopper 1061. An ash discharge telescopic cylinder 1063 is provided at the rear side of the ash hopper 1061. The telescopic rod of the ash discharge telescopic cylinder 1063 is connected to the ash discharge opening and closing plate 1062 via a connector 1064, thereby driving the ash discharge opening and closing plate 1062 to slide back and forth. When the ash discharge telescopic cylinder 1063 extends, it is in the open ash discharge state; when the ash discharge telescopic cylinder 1063 retracts, it is in the closed ash discharge state. The aforementioned ash hopper assembly 106 has a simple and stable structure, realizing the automated removal of iron and wood shavings from the ash hopper 1061.

[0068] In this embodiment, a spiral conveyor bucket is provided at the rear bottom of the trolley parking platform 2. This bucket collects the iron and wood shavings unloaded from the cleaning trolley 1. The feed end of the iron / wood shaving spiral elevator 3 extends into the bucket, and the discharge end is located above the feed end of the iron / wood shaving separator 4. When the bucket is full of iron and wood shavings, the spiral elevator 3 lifts them into the separator 4 using a spiral upward motion. Since the iron / wood shaving spiral elevator 3 and the separator 4 are existing technologies, their specific structures are not described in detail here.

[0069] Please see Figure 12 , Figure 13 In this embodiment, the trolley parking platform 2 includes a trolley parking plate 201 for parking the trolley 1, pulleys 202 located at the four corners of the bottom of the trolley parking plate 201, and a linear guide rail 203 that restricts the sliding direction of the pulleys 202. The trolley parking plate 201 can move linearly along the linear guide rail 203 via the four pulleys 202, thereby facilitating the adjustment of the distance between the trolley parking plate 201 and the container 7. At the same time, the rear end of the trolley parking plate 201 is provided with an ash unloading notch 2011 for the trolley 1 to unload ash, and the spiral lifting conveyor bucket is placed directly below the ash unloading notch 2011.

[0070] On the other hand, the present invention provides a container assembly line cleaning method, applied to the above-mentioned container assembly line cleaning system, comprising the following steps:

[0071] 1) The cleaning cart 1 is parked on the cart parking platform 2 to wait for the container 7 to arrive.

[0072] 2) Container 7 is moved to the designated position in front of the car parking platform 2.

[0073] 3) The sweeping trolley 1 starts the front disc brush assembly 103 and the rear disc brush assembly 104, and enters the container 7 along the trolley parking platform 2; the front disc brush assembly 103 and the rear disc brush assembly 104 sweep the iron and wood shavings to the herringbone roller brush assembly 105 of the sweeping trolley 1, and as the sweeping trolley 1 moves forward, they are roller brushed into the dust collection hopper assembly 106 at the rear.

[0074] 4) When the cleaning trolley 1 reaches the end of container 7, the suction / rake / blow assembly 102 is lowered and moved back about 2 meters by the suction / rake / blow assembly retraction cylinder 108, and the iron and wood shavings in the blind spot at the front are rake to about 2 meters inside container 7 (at this time, the dust blowing air knife of the suction / rake / blow assembly 102 blows the iron and wood shavings in the corner of the end to a certain distance behind).

[0075] 5) The sweeping trolley 1 moves forward about 2 meters and throws the scraped iron and wood shavings into the dust collection hopper 106 through the front disc brush assembly 103, the rear disc brush assembly 104 and the herringbone roller brush assembly 105.

[0076] 6) After the cleaning trolley 1 exits the container 7, the residual iron and wood shavings are cleaned by the suction / rake / blow assembly 102 during the retreat.

[0077] 7) After cleaning is completed, the cleaning trolley 1 returns to the designated position of the trolley parking platform 2 and releases the collected iron and wood shavings into the spiral lifting conveyor bucket at the bottom of the rear side of the trolley parking platform 2, and then waits for the next container 7 to be cleaned.

[0078] 8) When the spiral conveyor bucket is full of iron shavings and wood shavings, the iron shavings / wood shavings spiral conveyor 3 lifts the iron shavings and wood shavings in the spiral conveyor bucket into the iron shavings / wood shavings separator 4.

[0079] 9) The iron shavings / wood shavings separator 4 separates the iron shavings and wood shavings and loads them into different woven bags in two directions, that is, the iron shavings are loaded into the iron shavings woven bag 5 and the wood shavings are loaded into the wood shavings woven bag 6.

[0080] 10) Repeat the cleaning process for the next time.

[0081] Using the above-mentioned cleaning method, automated docking with the container production line can be achieved, ensuring that the cleaning trolley 1 cleans up the iron and wood shavings inside the container 7, and the efficiency is high, which can meet the current production rhythm of the container 7 factory.
