[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] like Figure 1-Figure 6As shown, an embodiment of the present application provides a turnover box cleaning device, which is used for cleaning turnover boxes in cigarette factories. During the production process of cigarette factories, tobacco leaves need to be processed through multiple processes, among which turnover boxes are used to transfer and convey tobacco leaves. The turnover boxes are relatively large in size, and are usually rectangular box-type structures with an opening on one side. One end of the opening of the turnover box is hinged on the equipment frame. During operation, the turnover box is driven by driving components such as hydraulic cylinders to repeatedly flip over to realize the dumping and conveying of tobacco leaves. When the turnover box is flipped to a state where the opening is tilted downward, the tobacco leaves are dumped into the downstream equipment. When the turnover box is flipped to a state where the opening is facing upward, the upstream tobacco leaves are transported into the turnover box. This operation is repeated. After the turnover box dumps the tobacco leaves inside, a certain amount of residual tobacco leaves will adhere to its bottom and four walls. If the residual tobacco leaves are not removed in time, leaves from different batches will be mixed, affecting the process quality, and the residual tobacco leaves are prone to mold if they are in the turnover box for a long time. Therefore, the operator is required to clean the inside of the turnover box regularly. Usually, the operator uses a brush and a water pipe to rinse the inside of the turnover box. However, since the installation position of the turnover box is relatively high, the price is relatively high, the operator needs to work at a height, and is limited by the interference of other equipment components. It is very inconvenient for the operator to clean the opening of the turnover box. There are also areas inside the turnover box that are not easy to reach. The cleaning is not thorough enough and the whole process is time-consuming. The turnover box cleaning device of the present application is intended to improve the convenience of cleaning the turnover box, and can complete the cleaning work of the turnover box 91 comprehensively and quickly.

[0028] The turnover box 91 cleaning device includes a first frame, a second frame 12 and a third frame 13. The first frame is arranged near the turnover box 91 of the cigarette factory building. For example, a conveyor belt 92 is arranged downstream of the turnover box 91 of the factory building. The first frame is preferably straddled above the conveyor belt 92 and one side of the first frame is adjacent to the turnover box 91. The second frame 12 is arranged on the first frame, and the second frame 12 can be adjusted along the first direction on the first frame. The third frame 13 is arranged on the second frame 12, and the third step can be adjusted along the second direction on the second frame 12. The robot arm 2 0, the robot arm 20 is arranged on the third frame 13, the robot arm 20 includes a plurality of arm segments connected to each other in sequence, the arm segment at the end of the robot arm 20 is provided with a nozzle assembly, the nozzle assembly is used to spray and clean the inside of the turnover box 91, the nozzle can be connected to a water supply pipeline or an air supply pipeline, and then the inside of the turnover box 91 can be flushed or sprayed to clean, the plurality of arm segments of the robot arm 20 are hinged together in sequence, and the adjacent arm segments can swing relative to each other, and the swing drive between the adjacent arm segments can be realized by a motor or a hydraulic cylinder, and the arm segment at the initial end of the robot arm 20 is arranged on the third frame 13. The arm section of the initial end of the robot arm 20 is rotatably arranged on the third frame 13, and the rotation of the arm section of the initial end of the robot arm 20 on the third frame 13 can be realized by a motor, so that the multi-segment robot arm 20 can conveniently and flexibly reach various spaces in various directions, and cooperate with the adjustment of the second frame 12 on the first frame, and cooperate with the adjustment of the third frame 13 on the second frame 12, so that the end of the robot arm 20 can conveniently and flexibly reach various spaces inside the turnover box 91, and then can conveniently clean the inside of the turnover box 91, greatly reducing The labor intensity is reduced, the cleaning is more comprehensive, and the time consumption of the cleaning process of the turnover box 91 can be effectively reduced. In this embodiment, when the turnover box 91 needs to be cleaned, the turnover box 91 is turned over to a posture with the opening tilted downward, and then the position of the second frame 12 on the first frame is adjusted, and the position of the third frame 13 on the second frame 12 is adjusted, and then the various arm segments of the robot arm 20 are adjusted, so that the end arm segment of the robot arm 20 brings the nozzle assembly into the internal space of the turnover box 91, and the position of the nozzle assembly is adjusted while cleaning to comprehensively clean the inside of the turnover box 91.

[0029] Preferably, the first direction is parallel to the flipping plane of the turnover box 91, and the second direction is perpendicular to the first direction. In this embodiment, when the turnover box 91 is flipped, the plane where the turnover box 91 flips and swings is taken as its flipping plane, the first direction is parallel to the flipping plane, and the second direction and the first direction are perpendicular to each other. More preferably, one of the first direction and the second direction can be a horizontal direction. Preferably, the first direction and the second direction are both horizontal directions. In this way, after the turnover box 91 is flipped to the point where the opening is tilted downward, when the second frame 12 is adjusted on the first frame, the second frame 12 is moved away from or close to the turnover box 91. When the third frame 13 is adjusted on the second frame 12, the lateral offset of the third frame 13 relative to the turnover box 91 is adjusted, so that the third frame 13 is more centered or more laterally offset relative to the turnover box 91. In this way, the position of the robotic arm 20 relative to the turnover box 91 can be flexibly adjusted. Combined with the swinging of multiple arm segments of the robotic arm 20, the nozzle assembly can be easily extended into the turnover box 91 and the interior of the turnover box 91 can be fully cleaned.

[0030] In one embodiment, the first frame includes two rails 110, and the rails 110 have an extended length. The length direction of the rails 110 extends along the first direction, and the two rails 110 are symmetrically arranged relative to the middle flip surface of the turnover box 91 in the second direction. The second frame 12 is arranged on the two rails 110. The definition of the middle flip surface of the turnover box 91 refers to the turnover box 91 being symmetrical relative to the middle flip surface, and the middle flip surface passes through the middle of the turnover box 91. The two rails 110 are symmetrically arranged relative to the middle flip surface, so that the second frame 12 can face the turnover box 91, which is more conducive to the alignment of the robot arm 20 and the turnover box 91. The second frame 12 spans the two rails 110 for reciprocating adjustment.

[0031] Preferably, the second frame 12 has an extended length along the second direction, and the two ends of the second frame 12 can be slidably set on the corresponding rails 110 along the first direction, and the third frame 13 can be slidably set on the second frame 12 along the second direction. One end of the second frame 12 can be slidably set on the rail 110 on one side, and the other end of the second frame 12 can be slidably set on the rail 110 on the other side. The third frame 13 can be slidably set on the second frame 12, and the two rails 110 can be set on the ground through supporting feet 111, so that the two rails 110 are respectively located on both sides along the upper side of the downstream conveyor belt 92 of the turnover box 91. In this way, the spatial layout is more reasonable, and it is also conducive to the internal intervention of the robot arm 20 and the turnover box 91.

[0032] A driving assembly for driving the second frame 12 to move and adjust along the first direction on the first frame is provided on the second frame 12, so as to facilitate the movement and adjustment of the second frame 12. In one embodiment, the driving assembly includes a driving wheel 31 and a driving device for driving the driving wheel 31 to rotate. The outer periphery of the driving wheel 31 is in contact with the track 110. When the driving wheel 31 rotates, the second frame 12 is driven to move and adjust along the first direction on the first frame. In this way, the position adjustment of the second frame 12 on the first frame is achieved in a wheel-like contact manner, and smooth stepless adjustment can be achieved. The adjustment is more stable and smooth. The driving device includes a driving motor 32 and a driving shaft 33. The driving motor 32 is arranged on the second frame 12, and the driving shaft 33 is rotatably arranged on the second frame 12, and the two ends of the driving shaft 33 are respectively connected to the driving wheel 31 and the driving motor 32.

[0033] In one example, the second frame 12 is a rectangular beam structure, the third frame 13 is arranged on the side of the second frame 12 facing the turnover box 91, a motor frame 34 is arranged on the side of the second frame 12 away from the turnover box 91, the drive motor 32 is installed on the motor frame 34, a mounting plate 121 is arranged at each end of the second frame 12, the mounting plate 121 is vertically connected to the second frame 12, one end of the second frame 12 is against the flat side of the mounting plate 121, and a slider is arranged on the other side of the mounting plate 121 122, the slider 122 can be slidably pressed against the top of the track 110, a convex strip 112 can be set on the track 110, and the convex strip 112 is set along the direction of the track 110, and a slide groove 1221 is set at the bottom of the slider 122, so that the slider can be adapted to the slide groove 1221, thereby improving the stability of the slider 122 when sliding, and improving the overall stability of the second frame 12, two drive shafts 33 are set, respectively used to cooperate with the tracks 110 on both sides, and one end of the drive shaft 33 is connected to the drive motor 32, The other end of the driving shaft 33 passes through the mounting plate 121, and a bearing can be arranged between the driving shaft 33 and the mounting plate 121 to facilitate the rotation of the driving shaft 33. The end of the driving shaft 33 extending out of the mounting plate 121 is used to install the driving wheel 31. A slideway 113 can be arranged on the side of the track 110, and the slideway 113 is arranged along the direction of the track 110. The bottom of the driving wheel 31 abuts against the top of the slideway 113, so that the driving wheel 31 can roll along the slideway 113. A rubber anti-skid layer is arranged on the periphery of the driving wheel 31. Driven by the motor 32, the driving wheel 31 rotates, and then friction is generated between the driving wheel 31 and the slide 113, so that the second frame 12 can be adjusted on the first frame. The setting of the driving shaft 33 and the driving wheel 31 is symmetrical with respect to the middle flip surface of the turnover box 91, so that the adjustment of the second frame 12 is smoother. The adjustment of the third frame 13 on the second frame 12 can adopt the same driving wheel 31 structure as mentioned above, or the ball screw structure can be used to drive the third frame 13 to move and adjust on the second frame 12.

[0034] In some embodiments, the nozzle assembly can be a spray head 40, such as Figure 4 , 5 As shown, the nozzle 40 is disposed on the arm section at the end of the mechanical arm 20. Preferably, the nozzle assembly includes a base 51. Figure 6 As shown, a nozzle body 52 is provided on the base 51, and an upstream port and a downstream port that are interconnected are provided on the nozzle body 52. ​​The upstream port is used to connect with a water supply pipe or an air supply pipe, so that the downstream port can blow air or spray water outward to clean the inside of the turnover box 91. In this embodiment, the base 51 can be connected to the end arm section of the robot arm 20, so as to drive the nozzle body 52 to various positions inside the turnover box 91, so that the downstream port of the nozzle body 52 sprays water or air toward the inside of the turnover box 91 to clean the inside of the turnover box 91. Preferably, there are multiple downstream ports on the nozzle body 52, and each downstream port is connected to a nozzle 53 respectively. The nozzle 53 can have the effect of extending the length, which is more convenient for cleaning the inside of the turnover box 91. The lengths of the various nozzles 53 are not the same. One end of the nozzle 53 is connected to the downstream port, and the end of the nozzle 53 is used to spray water or air outward. The lengths of the various nozzles 53 are different, and the end openings of the various nozzles 53 can also be set in different directions. The water or air spray is more comprehensive, thereby improving the comprehensiveness of the cleaning of the interior of the turnover box 91. More preferably, a camera 54 can also be set on the base 51, and the camera 54 is set close to the nozzle body 52. ​​The camera 54 can collect real-time video information inside the turnover box 91, which can be displayed through an external display for easy observation. In this embodiment, the end opening of a nozzle 53 on the nozzle body 52 can be facing the camera 54. When the air flow is blown for cleaning, tobacco debris on the outer surface of the camera 54 can be blown away to avoid obstruction.
