[0033] The embodiment of the present invention discloses a logistics cargo box disinfection device, which is mainly used for disinfecting cargo boxes, such as foam boxes.

[0034] like Figure 1 and 2As shown, a logistics cargo box disinfection device in this embodiment includes a cabinet 100 and a conveying cylinder 110 rotatably arranged on the cabinet 100. Conveying components for conveying the cargo box 101 are relatively arranged in the conveying cylinder 110. One of the two conveying components is a feeding conveying component 120a, and the other is a discharging conveying component 120b. In actual use, the cabinet 100 is used to support the conveying cylinder 110, so that the conveying components in the conveying cylinder 110 can cooperate with an existing conveying mechanism (such as a conveyor belt or roller line) to achieve the completion of the disinfection operation of the cargo box 101 during the transportation process;

[0035] Among them, a bottom spray disinfection component for disinfecting the bottom of the cargo box 101 is provided in the conveying cylinder 110 and located between the two conveying components, and a side spray disinfection component for disinfecting the sides of the cargo box 101 is provided in the conveying cylinder 110 and located at the feed conveying component 120a;

[0036] In this embodiment, the conveying surfaces of the feed conveyor assembly 120a and the discharge conveyor assembly 120b are flush, and one end of each extends out of the corresponding end of the conveying cylinder 110 to cooperate with the existing conveying mechanism. With this structure, the feed conveyor assembly 120a can better convey the cargo box 101 to be sterilized into the conveying cylinder 110, and the discharge conveyor assembly 120b can output the sterilized cargo box 101 from the conveying cylinder 110;

[0037] Among them, the structures of the feed conveying assembly 120a and the discharge conveying assembly 120b both include relatively arranged mounting plates 241, and the mounting plates 241 are fixedly connected to the side walls of the conveying cylinder 110 by bolts. Rotatable rollers 242 are arranged between the corresponding mounting plates 241 and at both ends, and a conveyor belt 243 is sleeved between the rollers 242.

[0038] In this embodiment, a transfer assembly is provided within the conveying cylinder 110 and above the conveying assembly. The transfer assembly is used to transfer the cargo box 101 on the feed conveying assembly 120a to the discharge conveying assembly 120b. A laser length measuring instrument 130 is provided on the conveying cylinder 110 and at the input end of the feed conveying assembly 120a for detecting the length of the cargo box 101.

[0039] It also includes a controller, which is used to receive the detection signal of the laser length measuring instrument 130 and control the transfer component to transfer the cargo box 101.

[0040] In this embodiment, by means of the transfer assembly and the rotation arrangement of the coordinated conveying cylinder 110, in actual use, the transfer assembly is initially located above the feed conveying assembly 120a. When the feed conveying assembly 120a conveys the cargo box 101 to the position directly below the transfer assembly, the conveying cylinder 110 rotates 180° to enable the cargo box 101 conveyed on the feed conveying assembly 120a to be moved to the transfer assembly. When the transfer assembly moves to the position directly below the discharge conveying assembly 120b, the conveying cylinder 110 rotates and resets, moving the cargo box 101 on the transfer assembly to the discharge conveying assembly 120b, thereby realizing the transfer of the cargo box 101.

[0041] In this embodiment, the bottom spray disinfection assembly is installed between the feed conveying assembly 120a and the discharge conveying assembly 120b, so that when the transfer assembly is transferring the cargo box 101, the bottom spray disinfection assembly can spray disinfectant on the bottom side of the cargo box 101, thereby disinfecting the bottom side of the cargo box 101;

[0042] The side spray disinfection assembly is installed on the feed conveyor assembly 120a and is located in front of the initial position of the transfer assembly. Even before the feed conveyor assembly 120a transports the cargo box 101 to the position directly below the transfer assembly, the side spray disinfection assembly can spray disinfectant on the sides of the cargo box 101, thereby disinfecting the sides of the cargo box 101.

[0043] In actual use, the bottom spray disinfection assembly of this embodiment includes a first nozzle 200 whose two ends are fixedly connected to the inner wall of the conveying cylinder 110. A plurality of first nozzles 201 are evenly distributed along the axial direction of the first nozzle 200. The first nozzle 200 is used to store disinfectant, and the first nozzle 201 is used to spray the disinfectant onto the bottom side of the cargo box 101; the side spray disinfection assembly includes a second nozzle 210 arranged along the circumference of the conveying cylinder 110 and in an arc shape. The second nozzle 210 is fixedly connected to the inner wall of the conveying cylinder 110 through a connecting rod. A plurality of second nozzles 211 are evenly distributed along the circumference of the second nozzle 210. The second nozzle 210 is used to store disinfectant, and the second nozzle 211 is used to spray the disinfectant onto the side of the cargo box 101.

[0044] In this embodiment, in order to better disinfect all six surfaces of the cargo box 101, end-spray disinfection assemblies (not shown in the figure) are installed at both ends of the transfer assembly for spraying disinfectant on the front and rear ends of the cargo box 101. The end-spray disinfection assembly includes a spray pipe and a third nozzle provided on the spray pipe.

[0045] Combine Figure 7 As shown, in this embodiment, a guide assembly for guiding the cargo box 101 is provided in the conveying cylinder 110 and located at the side spray disinfection assembly.

[0046] The guide assembly includes a guide plate 711 located above and opposite to the feed conveying assembly 120 a , and a third cylinder 710 for driving the guide plate 711 to move relative to each other is provided in the conveying cylinder 110 .

[0047] In this embodiment, the laser length measuring instrument 130 is capable of detecting the width and height of the cargo box 101 entering the feed conveying assembly 120a. During actual installation, it is fixedly installed at the corresponding end of the conveying cylinder 110 through the mounting plate 721. During actual use, the laser length measuring instrument 130 is located directly above the center position of the feed conveying assembly 120a. The laser length measuring instrument 130 is connected to the controller, and the third cylinder 710 is connected to the controller. The controller controls the third cylinder 710 to drive the guide plate 711 to move relative to each other according to the width of the cargo box 101 detected by the laser length measuring instrument 130, so that the guide plates 711 on both sides of the feed conveying assembly 120a move to both sides of the cargo box 101, which are used to guide and limit the cargo box 101, thereby avoiding the displacement of the cargo box 101 during the rotation of the conveying cylinder 110, and ensuring that the cargo box 101 is transferred to the transfer assembly.

[0048] Combine Figure 3-5 As shown, in this embodiment, the transfer assembly includes a transfer block 220 that is axially along the conveying cylinder 110 and can move along the conveying direction of the conveying assembly. The transfer block 220 extends outward from the side surface close to the inner wall of the conveying cylinder 110 to form a mounting portion 311. Clamp mounting grooves 312 are provided on both sides of the transfer block 220 along the axial direction thereof. Clamps 320 close to each other are installed in the clamp mounting grooves 312 through torsion springs. A driving groove 313 is provided in the transfer block 220 and is located between the clamp mounting grooves 312. A driving member for driving the two clamps 320 away from each other is provided in the driving groove 313.

[0049] A conveying member 230 that can be raised and lowered and is used to transport the cargo box 101 is provided on the transfer block 220 and located between the two clamping plates 320 .

[0050] In actual use of this embodiment, the transfer assembly is initially located above the guide assembly, so that the rotation of the conveying cylinder 110 can better move the cargo box 101 onto the conveying member 230. The splints 320 are arranged so that the splints 320 can rotate to both sides of the cargo box 101, so that the cargo box 101 is limited, so that the rotation of the conveying cylinder 110 can better move the cargo box 101 onto the conveying member 230. At the same time, the splints 320 can also limit the cargo box 101 during the process of the transfer assembly transferring the cargo box 101, so as to prevent the cargo box 101 from falling off the conveying member 230.

[0051] Among them, the conveying member 230 is used to carry the cargo box 101. The conveying member 230 includes a U-shaped conveying plate 370. A rotatable conveying roller 371 is provided between the conveying plates 370. The transfer block 220 is provided with a second cylinder 380 for driving the conveying plate 370 to rise and fall; wherein the conveying roller 371 abuts against and supports the cargo box 101, and the second cylinder 380 is connected to the controller. The controller controls the second cylinder 380 to drive the conveying plate 370 to rise and fall according to the height of the cargo box 101. Preferably, when the conveying member 230 carries the cargo box 101, there is a height difference between the bottom surface of the cargo box 101 and the conveying surfaces of the two conveying components, thereby facilitating the bottom spray disinfection component to disinfect the bottom surface of the cargo box 101;

[0052] During actual use, the transfer component is arranged directly above the center position of the two conveying components. The setting of the guide component is utilized to better ensure that the cargo box 101 is located at the center position of the feed conveying component 120a, so that it can better cooperate with the transfer component under the rotation of the conveying cylinder 110.

[0053] Combine Figure 6 As shown, in this embodiment, the driving member includes a screw rod 330 rotatably arranged in the driving groove 313 and a rotating rod 340 rotatably arranged on both sides of the screw rod 330, the rotating rod 340 is provided with a first bevel gear 611 and a winding wheel 612, the corresponding splint 320 on the mounting portion 311 is provided with a guide roller 350, the winding wheel 612 is provided with a traction rope 360 ​​connected to the corresponding splint 320 through the corresponding guide roller 350, a rotatable rotating shaft 620 is provided between the screw rods 330, and a second bevel gear 621 matching the corresponding first bevel gear 611 is provided at both ends of the rotating shaft 620, and a gear 622 is provided on the rotating shaft 620; a movable plate 630 is threadedly provided on the screw rod 330, and a tooth groove 631 matching the gear 622 is provided on the movable plate 630.

[0054] In actual use, the drive slot 313 is provided with openings on both sides, so that the traction rope 360 ​​can extend from the drive slot 313 to connect with the clamping plate 320. The guide roller 350, the winding wheel 612, and the traction rope 360 ​​are arranged so as to cooperate with the torsion spring. The winding of the traction rope 360 ​​can preferably drive the clamping plate 320 to clamp the cargo box 101.

[0055] In order to better achieve the cooperation between the splint 320 and the side wall of the cargo box 101, a clamping wheel 321 is provided at the outermost end of the splint 320 to abut against the corresponding side wall of the cargo box 101, wherein the rotation direction of the clamping wheel 321 is consistent with the movement direction of the cargo box 101 onto the conveying member 230. With this structure, the conveying cylinder 110 can be rotated to better achieve the transfer of the cargo box 101 to the conveying member 230.

[0056] The rotating shaft 620 is rotatably mounted in the driving groove 313 through the bearing seat. The first bevel gear 611, the second bevel gear 621 and the rotating rod 340 are arranged so that the rotating shaft 620 rotates to drive the first bevel gear 611 to rotate, and then drives the second bevel gear 621 to rotate and drives the rotating rod 340 to rotate, thereby realizing the rotation of the winding wheel 612 to retract and release the traction rope 360. The screw rod 330, the movable plate 630, the tooth groove 631 and the gear 622 are arranged so that the rotation of the screw rod 330 can drive the movable plate 630 to move, and then drives the gear 622 to rotate, thereby realizing the rotation of the rotating shaft 620.

[0057] In this embodiment, a first motor 401 for driving the screw rod 330 to rotate is provided on the end face of the transfer block 220.

[0058] In this embodiment, the first motor 401 is connected to the controller, and the controller controls the first motor 401 to start according to the width of the cargo box detected by the laser length measuring instrument 130, so that the splint 320 automatically adjusts to the two sides of the cargo box 101 to limit it.

[0059] In this embodiment, a slide groove with a T-shaped cross-section is provided on the side wall of the conveying cylinder 110 along its axial direction (not shown in the figure), and a slider (not shown in the figure) sliding in the slide groove is provided on the transfer block 220; a first cylinder 140 for driving the transfer block 220 to move back and forth is provided at the end of the conveying cylinder 110 corresponding to the discharge conveying component 120b.

[0060] Through this embodiment, through the coordinated setting of the slide groove and the slider, it is possible to better realize the axial movement of the transfer block 220 along the conveying cylinder 110, wherein the first cylinder 140 is connected to the controller, and the controller controls the first cylinder 140 to drive the transfer block 220 to move, thereby realizing the transfer of the cargo box 101 by the transfer assembly; wherein the first cylinder 140 is fixedly installed at the corresponding end of the conveying cylinder 110 through the mounting plate 721.

[0061] This embodiment also provides another driving structure for driving the transfer block 220 to move, which includes a second screw rod arranged between the mounting plates 721 at both ends of the conveying cylinder 110. The transfer block 220 is provided with a threaded hole 511 for the second screw rod to thread through. The mounting plate 721 is provided with a second motor for driving the second screw rod to rotate. The second motor is connected to the controller, and the controller controls the second motor to drive the transfer block 220 to move, thereby realizing the transfer of the cargo box 101 by the transfer component.

[0062] In this embodiment, the outer cover of the conveying cylinder 110 is provided with a relative second gear 111, and the cabinet 100 is provided with a rotating base 102 located on both sides of the conveying cylinder 110. The rotating base 102 is provided with a rotatable third gear 103 that cooperates with the corresponding second gear 111. The cabinet 100 is provided with a dual-axis motor 104 for driving the third gear 103 located on the same side of the conveying cylinder 110 to rotate.

[0063] In this embodiment, the dual-axis motor 104 is connected to the controller, and the controller controls the dual-axis motor 104 to drive the third gear 103 to rotate, thereby driving the second gear 111 to rotate synchronously, thereby realizing the reciprocating rotation of the conveying cylinder 110 above the cabinet 100;

[0064] During actual use, a proximity sensor connected to the controller is provided on the inner wall of the conveying cylinder 110, and the proximity sensor is arranged above the feed conveying assembly 120a, so that when the proximity sensor detects the cargo box 101, the feed conveying assembly 120a stops conveying, and the controller controls the dual-axis motor 104 to rotate the conveying cylinder 110 180°, thereby moving the cargo box 101 on the feed conveying assembly 120a to the transfer assembly, and then, the controller controls the first cylinder 140 or the second motor to drive the transfer assembly to move to the bottom of the discharge conveying assembly 120b. At this time, the controller controls the dual-axis motor 104 to rotate the conveying cylinder 110 180° in the opposite direction to reset it, and move the cargo box 101 on the transfer assembly to the discharge conveying assembly 120b, thereby completing the output of the sterilized cargo box 101.

[0065] Working principle: The cargo box 101 is transported to the conveying drum 110 by the feed conveying assembly 120a at intervals. When it enters the conveying drum 110, the laser length measuring instrument 130 detects the width of the cargo box 101 and sends a signal to the controller. The controller controls the third cylinder 710 according to the width signal to move the guide plate 711 to the corresponding position on one side of the feed conveying assembly 120a, and controls the first motor 401 to drive the splint 320 to move to the corresponding position and controls the second cylinder 380 to drive the conveying member 230 to adjust to the appropriate position. During this process, the feed conveying assembly 120a continues to transport the cargo box 101, and the side spray disinfection assembly disinfects the side of the cargo box 101. When the proximity sensor detects the cargo box 101, it is moved in. The material conveying component 120a stops conveying. At this time, the controller controls the dual-axis motor 4 to rotate the conveying cylinder 110 180°, thereby moving the cargo box 101 on the feed conveying component 120a to the transfer component. Then, the controller controls the first cylinder 140 or the second motor to drive the transfer component to move to the bottom of the discharge conveying component 120b. During this process, the bottom spray disinfection component and the end spray disinfection component disinfect the bottom and end surfaces of the cargo box 101. At this time, the controller controls the dual-axis motor 104 to rotate the conveying cylinder 110 180° in the opposite direction to reset it, and move the cargo box 101 on the transfer component to the discharge conveying component 120b, thereby completing the output of the disinfected cargo box 101, so that the outside of the cargo box is fully disinfected.

[0066] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
