[0019] The present invention has the following beneficial effects:

[0020] 1.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] See also Figure 1-Figure 6 As shown, the present invention is a modular cleaning device for logistics transportation, comprising a portal frame 1, at least two suspension cylinders 2 are vertically fixed on the crossbeam of the portal frame 1, and a cleaning box 3 is installed on the lower end surface of the piston rod of the suspension cylinder 2, and cleaning nozzles 4 are swingably installed at the four corners of the cleaning box 3, and the left and right side walls of the cleaning box 3 are provided with a clamping rotating mechanism 5, and the clamping rotating mechanism 5 is used to clamp the transported items into the cleaning box 3, and the bottom of the cleaning box 3 is provided with a sealing collection mechanism 7, and the sealing collection mechanism 7 is used to seal the bottom of the cleaning box 3 and collect the waste water generated after cleaning;

[0034] In the scheme designed by the present invention, therefore, the present invention vertically slides and sets the cleaning box 3 in the portal frame 1, first fixes the portal frame 1 on the shunt line of the logistics conveyor line through the mounting holes opened in the vertical plates on both sides, and suspends the cleaning box 3 above the conveyor line. When the conveyor line conveys the transported items, the camera assembly in front of the portal frame 1 will shoot the transported items. When it is found that there are adhesions or impurities on the surface of the photographed items, the conveyor line will shunt the transported items to the bottom of the portal frame 1, and the pistons of the two suspension cylinders 2 are controlled at this time. The rod is extended to drive the cleaning box 3 to descend and cover the transported objects to be cleaned, and then the clamping rotating mechanism 5 is controlled to work, so that it clamps and fixes the transported objects to be cleaned in the cleaning box 3, and then the clamped transported objects are driven upward inside the cleaning box 3, and then the piston rod of the suspension cylinder 2 is controlled to contract, so that it drives the cleaning box 3 to move upward to a certain height, and then the sealing and collecting mechanism 7 is operated to seal the bottom of the cleaning box 3, and then the cleaning equipment is controlled to work, so that it injects cleaning liquid into the swinging cleaning nozzle 4, and the cleaning liquid at the four corners is The washing nozzle 4 will focus on flushing the surface of the transported items. At the same time, the clamping and rotating mechanism 5 can drive the transported items to rotate in the cleaning box 3, which can speed up the cleaning effect of the transported items. The cleaned waste water will fall into the sealing collection mechanism 7 for collection and treatment to prevent it from dripping onto the conveying line below. When the transported items are cleaned, the cleaning box 3 can be controlled to be connected to the drying component to dry the cleaned transported items. When the transported items are cleaned, the sealing and collecting mechanism 7 is opened first, and the collected waste water will not drip automatically. Then the cleaning box 3 is controlled to descend so that the lower opening of the cleaning box 3 fits onto the conveying line. Then the transported items clamped by the clamping and rotating mechanism 5 are controlled to descend in the cleaning box 3 so that the cleaned transported items fall and contact the conveying line, and then the transported items are released from the clamping. The cleaning box 3 rises under the contraction of the suspension cylinder 2, which makes it easier for the conveying line to continue to quickly transport the cleaned transported items, and will not affect the normal transport of the subsequent transported items by the conveying line, and can improve the rapid cleaning effect of the transported items to be cleaned.

[0035] As an embodiment of the present invention, the clamping and rotating mechanism 5 includes a main wheel shaft 51, a driving gear 52, a clamping cylinder 53, a rotating sleeve 54, a driven gear 55, a clamping plate 56 and a sliding limit assembly 6. The main wheel shaft 51 is rotatably mounted on the left and right side walls of the cleaning box 3, and the driving gear 52 is fixed on the outer side of the main wheel shaft 51 extending out of the cleaning box 3. The clamping cylinder 53 is horizontally rotatably mounted on the left and right side walls of the cleaning box 3 through the rotating sleeve 54, and The piston rod of the clamping cylinder 53 extends into the cleaning box 3. The clamping cylinder 53 is located below the main wheel shaft 51. A driven gear 55 is fixed to the cylinder body of the clamping cylinder 53, and the driven gear 55 is slidably engaged with the driving gear 52. A clamping plate 56 is installed on the end face of the piston rod of the clamping cylinder 53. A sliding limit assembly 6 is arranged above the clamping cylinder 53, and the sliding limit assembly 6 is used to drive the clamping plate 56 to slide up and down in the cleaning box 3.

[0036] When the cleaning object is in the lowered cleaning box 3, the piston rod of the clamping cylinder 53 is first controlled to retract, so that the clamping plate 56 is attached to the wall of the cleaning box 3, and then the sliding limit assembly 6 is controlled to work, so that it drives the clamping plate 56 to move down to the two side walls of the transported object, and then the piston rod of the clamping cylinder 53 is controlled to extend, so that it drives the clamping plate 56 to clamp and fix to the two sides of the transported object, and then the sliding limit assembly 6 is controlled to work, so that it drives the clamped transported object to move upward in the cleaning box 3, so that the bottom of the transported object is separated from the conveyor line, and when the clamping cylinder 53 moves upward, the driven gear 55 is meshed with the driving gear 52, and then the sealing and collecting mechanism 7 is operated to seal the bottom of the cleaning box 3, and then the servo motor fixed to the inner wall of the cleaning box 3 is controlled to work, so that it drives the driving gear 52 and the driven gear 55 to work through the main wheel shaft 51, and then the symmetrical clamping plate 56 is moved. 56 will drive the clamped transported items to rotate in the cleaning box 3, so that the swinging cleaning nozzle 4 can fully clean the clamped and rotating transported items. When the transported items are cleaned and dried, the sealing collection mechanism 7 is opened first, and then the sliding limit assembly 6 is controlled to work, so that it drives the clamping cylinder 53 and the clamped transported items to slide downward in the cleaning box 3, and the driven gear 55 will be disengaged from the driving gear 52, so that the transported items will extend out of the cleaning box 3, and then the cleaning box 3 is controlled to descend, so that the cleaned transported items fall onto the conveyor line, and then the piston rod of the symmetrical clamping cylinder 53 is contracted, so that it drives the clamping plate 56 to disengage from the clamping of the transported items, and then the cleaning box 3 rises, so that the conveyor line continues to transport and process the cleaned transported items, and because the clamping plate 56 drops to the lowest position in the cleaning box 3, it is convenient for the cleaning box 3 to descend again to clamp the next transported item to be cleaned.

[0037] As an embodiment of the present invention, the sliding limit assembly 6 includes a guide slider 61, a connecting block 62, a limit block 63, a sliding cylinder 64 and a mounting plate 65. The left and right side walls of the cleaning box 3 are vertically provided with a sliding guide groove 31, and the sliding guide groove 31 is located below the main wheel shaft 51. The guide slider 61 is slidably arranged in the sliding guide groove 31, and the clamping cylinder 53 is rotatably installed in the guide slider 61 through the rotating sleeve 54. The rear end of the cylinder body of the clamping cylinder 53 extends to the door On the vertical plate of the frame 1, the rotating sleeve 54 on the cylinder body of the clamping cylinder 53 is connected with a connecting block 62, and the vertical plates on both sides of the door frame 1 are vertically provided with a limiting guide groove 10, and the clamping cylinder 53 is rotatably installed in the limiting guide groove 10 through the limiting block 63 and the rotating sleeve 54, and the upper end surface of the connecting block 62 is connected to the piston rod of the vertically arranged sliding cylinder 64, and the left and right side walls of the cleaning box 3 are horizontally fixed with a mounting plate 65, and the mounting plate 65 is connected to the cylinder body of the vertical sliding cylinder 64;

[0038] In the scheme designed by the present invention, when it is necessary to lift the clamped transported items upward, it is necessary to control the piston rod of the sliding cylinder 64 to contract, so that it drives the cylinder body of the clamping cylinder 53 to slide upward through the connecting block 62, and at this time the guide slide block 61 will slide upward in the sliding guide groove 31, and at the same time the limit block 63 at the tail of the clamping cylinder 53 will slide downward in the limit guide groove 10, and then the cooperation of the limit block 63 and the guide slide block 61 can limit the clamping cylinder 53 to prevent it from swinging, and when the driven gear 55 on the clamping cylinder 53 is meshed with the driving gear 52, the sliding cylinder 64 is not working at this time, so that it is convenient for the clamping cylinder 53 to drive the transported items clamped and fixed by the clamping plate 56 to rotate and clean in the cleaning box 3. The guide slider 61, the connecting block 62 and the limit slider are all rotatably connected to the cylinder body of the clamping cylinder 53 through the rotating sleeve 54, so that they will not affect the normal operation of the clamping cylinder 53; and the piston rod of the sliding cylinder 64 is extended, and the clamping cylinder 53 can be driven to slide downward through the connecting block 62, so as to facilitate the clamped transport items to fall onto the conveyor line; at the same time, the extension amount of the piston rod of the sliding cylinder 64 can be controlled according to the height of the transport items to be cleaned, so that the clamping plate 56 can clamp to different positions of the transport items to be cleaned, and will not affect the meshing of the driven gear 55 and the driving gear 52, and will not cause the transport items to be unable to fully enter the cleaning box 3, and will not affect the normal sealing processing of the cleaning box 3 by the sealing collection mechanism 7.

[0039] As an embodiment of the present invention, the clamping disk 56 is an annular corrugated bag 561, and the inner ring surface of the annular corrugated bag 561 is fixed to the piston rod end face of the clamping cylinder 53 through a circular ring disk 562, and the inner side surface of the annular corrugated bag 561 is connected to an air pipe; in the scheme designed by the present invention, the control system can control the air pump to introduce gas into the air pipe according to the size of the transported items to be cleaned, so that the gas enters the annular corrugated bag 561, and then the annular corrugated bag 561 will expand and become larger on the outer ring surface of the circular ring disk 562, thereby increasing the diameter of the clamping disk 56, thereby facilitating the clamping and fixing of larger transported items, and the gas in the annular corrugated bag 561 is extracted to shrink the annular corrugated bag 561, thereby facilitating the clamping and fixing of small transported items.

[0040] As an embodiment of the present invention, the sealing collection mechanism 7 includes a sealing plate 71, a double-rotation screw 72, an L-shaped slider 73 and a sealing stopper 74. The front and rear sides of the bottom of the cleaning box 3 are provided with flush grooves 32, and the sealing plates 71 are slidably arranged in the symmetrical flush grooves 32. The left and right inner walls of the cleaning box 3 are horizontally provided with sliding guide grooves 33, and the double-rotation screw 72 is rotatably arranged in the sliding guide grooves 33. The double-rotation screw 72 is symmetrically mounted with an L-shaped slider 73 through two screw nut pairs. The lower surface of the vertical block of the L-shaped slider 73 is connected to the innermost upper surface of the sealing plate 71. The outer end surface of the sealing plate 71 is fixed with a sealing stopper 74, and the thickness of the sealing stopper 74 is greater than the thickness of the sealing plate 71.

[0041] In the scheme designed by the present invention, when the transported articles to be cleaned are clamped and transferred to the inside of the cleaning box 3, and the bottom of the cleaning box 3 needs to be sealed, the servo motor fixed on the front side or the rear side of the cleaning box 3 is controlled to work, so that it drives the two double-rotation screws 72 to rotate synchronously, and then drives the symmetrical sealing slide plates 71 to slide synchronously to the bottom of the cleaning box 3 for sealing through the L-shaped slider 73. The symmetrical L-shaped slider 73 is fixed to the upper end surface of the sealing slide plate 71, so that it can both suspend and fix the sealing slide plate 71 and drive the sealing slide plate 71 to slide horizontally in the flush groove 32. At the same time, the bottom end surface of the sealing slide plate 71 is flush with the bottom of the cleaning box 3, so that it will not interfere with the normal descent of the cleaning box 3 to fit onto the conveyor line; and the two double-rotation screws 72 rotate in opposite directions, which can drive the L-shaped slider 73 The sealing plate 71 slides in the sliding guide groove 33 toward the front and rear walls of the cleaning box 3, thereby facilitating the opening of the sealing plate 71, so that the transported items after cleaning in the cleaning box 3 can fall and be placed on the conveyor line for normal transportation. The design of the sealing baffle 74 can seal the gap between the sealing plate 71 and the front and rear side walls of the cleaning box 3 after the sealing plate 71 is sealed to the bottom of the cleaning box 3, so as to prevent the cleaning waste water from flowing out of the cleaning box 3. The left and right side walls of the sealing plate 71 are in sliding contact with the inner wall of the cleaning box 3 through elastic silicone, so that it can achieve the effect of contact sealing. The L-shaped slider 73 can also limit the sealing plate 71 that slides outward, preventing the sealing plate 71 from completely extending from the flush groove 32, which would cause the sealing plate 71 to be unable to seal the bottom of the cleaning box 3 again.

[0042] As an embodiment of the present invention, a water accumulation chamber 711 is provided inside the sealing slide plate 71, and a filter mesh hole 712 is provided on the upper chamber wall of the water accumulation chamber 711, and the bottom thereof is designed as a slope surface, a collecting chamber 741 is provided on the sealing baffle 74, and the collecting chamber 741 is connected to the water accumulation chamber 711, and a sewage pipe 75 is connected to the left end surface of the sealing baffle 74, and a suction hose 76 is connected to the sewage pipe 75;

[0043] In the scheme designed by the present invention, when the clean waste water falls on the sealing plate 71, the filter mesh holes 712 opened on the sealing plate 71 will intercept the falling large pieces or pieces of debris, and the cleaned waste water will directly fall into the water accumulation chamber 711 through the filter mesh holes 712, and then flow into the collection chamber 741 through the slope surface, and then be sucked out through the suction hose 76 connected to the sewage pipe 75, so as to prevent the cleaned waste water from accumulating on the sealing plate 71, which will not only increase the weight borne by the sealing plate 71, but also cause part of the waste water to drip from the cleaning box 3, and enable the sealing plate 71 to not only seal the bottom of the cleaning box 3, but also enable the sealing plate 71 to act as a collecting filter box, so that it can filter and intercept the mixed debris in the cleaned waste water, and then directly collect and discharge the waste water, and the suction hose 76 will slide synchronously with the sealing plate 71, and will not interfere with the normal sliding of the sealing plate 71.

[0044] As an embodiment of the present invention, the sealing slide plate 71 is located at the upper surface of the end of the cleaning box 3 and is provided with a collecting groove 713 horizontally on the left and right sides, and a dirt baffle plate 77 is vertically installed on the rear groove wall of the collecting groove 713, and a discharge inclined hole is provided between the collecting groove 713 and the water accumulation chamber 711; in the scheme designed by the present invention, when the sealing slide plate 71 slides open, the upper surface of the sealing slide plate 71 will fit the groove wall of the flush groove 32 and move outward, and then the groove wall of the flush groove 32 will intercept the filtered residual debris on the sealing slide plate 71, so that the debris will not follow the sealing slide plate 71 to slide out of the cleaning box 3, and when the collecting groove 713 opened on the sealing slide plate 71 When it is close to the flush groove 32, the debris accumulated and intercepted on the sealing slide 71 will enter the collecting groove 713 for collection. At the same time, the dirt baffle 77 can block the debris entering the collecting groove 713 to prevent the sealing slide 71 from sliding to the extreme position. The debris gathered on the sealing slide 71 falls onto the conveyor line, which will affect the clean transportation effect of the conveyor line on the transported items. At the same time, it is difficult to collect and process the debris filtered and intercepted by the sealing slide 71. When wastewater enters the collecting groove 713, the wastewater will enter the water accumulation chamber 711 through the discharge inclined hole, so that a large amount of wastewater will not accumulate in the collecting groove 713, which will affect the collection of debris.

[0045] As an embodiment of the present invention, the bottom of the collecting tank 713 is through-opened, and a sealing door 78 is rotatably installed at the bottom of the collecting tank 713, and a buckle block 8 is fixed below the left and right side walls of the cleaning box 3, and a collecting box 9 is detachably installed at the bottom of the cleaning box 3, and elastic buckle strips 91 are fixed to the left and right end surfaces of the collecting box 9, and the elastic buckle strips 91 are buckled on the buckle block 8 through the buckle holes provided;

[0046] In the scheme designed by the present invention, when a certain amount of debris is collected in the collecting trough 713, the processing personnel will raise the cleaning box 3 to the highest position, then put the collecting box 9 under the cleaning box 3, and correspond to the sealing door 78 rotatably installed at the bottom of the collecting trough 713, and then snap the elastic snap-fitting strips 91 at the left and right ends of the collecting box 9 to the snap-fitting block 8 through the snap-fitting holes, so as to facilitate the installation of the collecting box 9 to the bottom of the cleaning box 3, and then rotate to open the sealing door 78, so that the debris collected in the collecting trough 713 can fall into the collecting box 9, so as to facilitate the rapid discharge and collection of the debris collected in the collecting trough 713, and then rotate the sealing door 78 to seal the bottom of the collecting trough 713, and snap the elastic snap-fitting strips 91 at the two end surfaces of the collecting box 9 from the snap-fitting blocks. 8, so that it is convenient to remove the collection box 9 from the cleaning box 3, so that it will not affect the cleaning box 3 from descending and fitting onto the conveyor line. The present invention can install the snap-fit ​​block 8 to the middle position of the left and right side walls of the cleaning box 3, and make the box opening of the collection box 9 larger than the width of the two collection grooves 713, so that after the symmetrical sealing slide plate 71 is slid and sealed to the bottom of the cleaning box 3, the two sealing doors 78 can be opened, so that the debris collected in the collection grooves 713 opened on the two sealing slide plates 71 can fall into the same collection box 9 for collection. At this time, the cleaning nozzle 4 sprays the cleaning solution to rinse the collection groove 713, preventing the intercepted and filtered debris from adhering to the groove wall of the collection groove 713, thereby affecting the collection effect of the collection groove 713 on the filtered debris again.

[0047] The present invention provides a cleaning method for the modular logistics transportation cleaning device, the method comprising the following steps:

[0048] S1: When the conveyor line is transporting the transported items, the camera assembly in front of the gantry 1 will take pictures of the transported items. If adhesion or impurities are found on the surface of the photographed items, the conveyor line will divert the transported items to the bottom of the gantry 1;

[0049] S2: The suspension cylinder 2 drives the cleaning box 3 to descend to the conveyor line and covers the transported items to be cleaned;

[0050] S3: The clamping and rotating mechanism 5 and the sliding and limiting assembly 6 work to clamp the transported items entering the cleaning box 3 and move them into the cleaning box 3, and then control the piston rod of the suspension cylinder 2 to contract, so that it drives the cleaning box 3 to move upward;

[0051] S4: the sealing collection mechanism 7 works to seal the bottom of the cleaning box 3, and then controls the multiple swinging cleaning nozzles 4 to spray the cleaning solution until the clamped transported items are cleaned by the cleaning equipment;

[0052] S5: Then the sealing collection mechanism 7 is opened from the bottom of the cleaning box 3, and the piston rod of the suspension cylinder 2 is extended to make the cleaning box 3 fall to the surface of the conveyor line. The sliding limit assembly 6 and the clamping rotation mechanism 5 work to put the cleaned transported items onto the conveyor line, and then the suspension cylinder 2 drives the cleaning box 3 to move upward, so that the conveyor line continues to transport the cleaned transported items.
