[0008] The cleaning section has a cleaning chamber, which includes an openable and closable inlet end and an outlet end. The cleaning chamber is equipped with a cleaning unit that can clean in multiple directions. The top of the cleaning chamber is connected to a negative pressure dust collection device, and the bottom is connected to a discharge device.

[0009] The conveying section is provided through the inlet and outlet ends of the cleaning chamber to carry the object to be cleaned.

[0010] The cleaning chamber is provided with a rotating part at its outlet end. The rotating part can rotate the object to be cleaned from -90° to 90° so that the object can be rotated for cleaning.

[0011] The control unit is signal-connected to the cleaning unit and the conveying unit, and can control the conveying unit to reciprocate to perform the first cleaning. When the object to be cleaned triggers the transfer unit, the control unit can be reversed to perform the second cleaning.

[0012] The multi-directional cleaning includes cleaning from above, below, and sides. The first cleaning cannot clean both ends of the object to be cleaned. After the object is rotated by the repositioning part, both ends of the object can be cleaned laterally. The reverse direction refers to the direction from the outlet end to the inlet end, and conversely, the forward direction is the direction from the inlet end to the outlet end.

[0013] Furthermore, the transfer unit includes a blocking unit and a clamping unit. The blocking unit can block the forward movement of the object to be cleaned; the clamping unit includes an upper clamp and a lower clamp that can move towards or away from each other, and the upper and lower clamps can rotate synchronously under the control of the control unit. Thus, the clamping unit can clamp or release the object to be cleaned, and can also clamp and rotate the object to be cleaned to clean uncleaned surfaces.

[0014] Furthermore, the blocking unit and the clamping unit achieve their functions through the following structure:

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0046] Example 1

[0047] A fully automatic cleaning device includes a cleaning unit 1, a conveying unit, and a control unit, etc. Figure 1 As shown, the cleaning section 1 has a cleaning chamber, which includes an openable and closable inlet and outlet. The cleaning chamber contains a multi-directional cleaning unit. A negative pressure dust collection device is connected to the top of the cleaning chamber, and a discharge device is connected to the bottom. In this embodiment, the cleaning section 1 is mounted on a cleaning section bracket 4. For ease of disassembly and maintenance, the cleaning chamber includes an upper sealed chamber 9 and a lower sealed chamber 10, connected and fastened together by a connector 12. Figure 2 As shown.

[0048] In this embodiment, the inlet end and the outlet end are respectively provided with opening and closing devices. The opening and closing device at the inlet end is an inlet airtight movable door 15, and the opening and closing device at the outlet end is an outlet airtight movable door 16.

[0049] The negative pressure dust collection device is a negative pressure dust collector 14.

[0050] The discharge device includes a receiving hopper 11 and a discharge valve 13 located at the bottom of the cleaning chamber and arranged from top to bottom.

[0051] The cleaning chamber is further equipped with a rotating part located at the sealed movable door 16 at the outlet. The rotating part can rotate the object to be cleaned from -90° to 90°, so that the object can be cleaned by rotating the angle. In this embodiment, the object to be cleaned is a cargo pallet 6.

[0052] The conveying section is provided with an inlet sealed movable door 15 and an outlet sealed movable door 16 that pass through the cleaning chamber to carry and convey the pallet 6.

[0053] The control unit is signal-connected to the cleaning unit 1 and the conveying unit, and can control the conveying unit to reciprocate to perform the first cleaning. When the tray 6 triggers the transfer unit, it controls the conveying unit to run in reverse to perform the second cleaning. The reverse direction refers to the direction from the outlet sealed movable door 16 to the inlet sealed movable door 15, and vice versa. The forward direction is the direction from the inlet sealed movable door 15 to the outlet sealed movable door 16.

[0054] like Figure 3 As shown, the transfer unit includes a blocking unit and a clamping unit, wherein the blocking unit is a blocker 26. The blocker 26 can prevent the tray 6 from moving forward. The clamping unit includes an upper clamp 24 and a lower clamp 25 that can move in opposite directions or in reverse, and the upper clamp 24 and lower clamp 25 can rotate synchronously under the control of the control unit. Thus, the clamping unit can clamp or release the tray 6, and can also clamp the tray 6 and rotate it to clean uncleaned surfaces.

[0055] In this embodiment, as Figure 3 , 4 As shown in Figure 5, the blocker 26 and the clamping unit achieve their functions through the following structure:

[0056] The blocker 26 includes a first drive mechanism 32, a rotating arm 33 and a baffle 34 arranged in sequence. The first drive mechanism 32 can drive the rotating arm 33 to rotate, and the baffle 34 can block or allow the tray 6 to pass under the drive of the rotating arm 33.

[0057] The upper gripper 24 includes a second drive mechanism 29, a first telescopic arm 30, and a first clamping part 31 connected from top to bottom. The second drive mechanism 29 can drive the first telescopic arm 30 to extend, retract, and / or rotate, and drive the first clamping part 31 to move closer to or away from the tray 6. The lower gripper 25 has the same structure as the upper gripper 24, but faces the opposite direction.

[0058] like Figure 3 As shown, the cleaning unit includes several sets of cleaning rollers, which are distributed on the bearing surface of the conveying part and on the upper part and both sides of the cleaning cavity.

[0059] The cleaning unit also includes several sets of purge branch pipes 23 arranged in the cleaning chamber. The purge branch pipes 23 are connected to an external compressed air supply source through an automatic compressed air valve 22 provided on the wall of the cleaning chamber. The open ends of the purge branch pipes 23 all point to the tray 6.

[0060] The conveying section includes an infeed section 7, a cleaning section, and an outfeed section 8. Each of the infeed section 7, the cleaning section, and the outfeed section 8 has a plurality of conveying rollers 17 arranged along the length of the conveying section on its bearing surface. The cleaning section is located within the cleaning chamber, and the cleaning rollers on the conveying section are arranged between the conveying rollers 17 of the cleaning section. The rotational speed of the cleaning rollers on the conveying section is greater than the rotational speed of the conveying rollers 17.

[0061] In this embodiment, as Figure 3 As shown, the bearing surface of the sweeping section is a horizontal mounting bracket 18 located in the middle of the sweeping unit. An upper bracket 27 and a lower bracket 28 are respectively located on the upper and lower sides of the horizontal mounting bracket 18. The sweeping rollers are divided into an upper sweeping roller 19, a lower sweeping roller 20, and a side sweeping roller 21. The upper sweeping roller 19 is mounted on the upper bracket 27, the lower sweeping roller 20 is mounted on the horizontal mounting bracket 18, and the side sweeping roller 21 is mounted on both sides of the horizontal mounting bracket 18 along the positive direction. A stopper 26 and an upper clamp 24 are respectively mounted on the upper bracket 27 via a first drive mechanism 32 and a second drive mechanism 29, and a lower clamp 25 is mounted on the lower bracket 28.

[0062] The horizontal mounting bracket 18, upper bracket 27 and lower bracket 28 are all installed inside the cleaning chamber along the direction from the inlet airtight movable door 15 to the outlet airtight movable door 16.

[0063] like Figure 1 As shown, the feeding section 7 and the feeding section 8 are respectively connected to the disassembly section and the assembly section. In this embodiment, corresponding to the pallet 6, the disassembly section and the assembly section are the pallet unloading machine 2 and the pallet assembly machine 3, respectively. The pallet unloading machine 2 is located near the entrance sealed movable door 15 and is used to disassemble the pallet 6; the pallet assembly machine 3 is located near the exit sealed movable door 16 and is used to assemble the cleaned pallet 6 according to a predetermined procedure.

[0064] In this embodiment, the inlet airtight movable door 15 and the outlet airtight movable door 16 have the same structure. Taking the inlet airtight movable door 15 as an example, Figure 6 As shown, the entrance sealed movable door 15 includes a sealing guide groove 37 opened on the cleaning chamber, an entrance sealed movable gate 36, and a fourth actuator 35. The fourth actuator 35 can drive the entrance sealed movable gate 36 to open and close along the sealing guide groove 37. The fourth actuator 35 is signal-connected to the control unit and its opening and closing are controlled by the control unit.

[0065] To achieve full automation, such as Figure 1As shown, in this embodiment, an entry detection device 38 and an exit detection device 40 are respectively installed on the outside of the entrance airtight door 15 and the exit airtight door 16, and an entry completion detection device 39 and an exit completion detection device 41 are respectively installed on the inside of the entrance airtight door 15 and the exit airtight door 16. The entry detection device 38, entry completion detection device 39, exit detection device 40, and exit completion detection device 41 are all signal-connected to the control unit and controlled by it.

[0066] The control unit includes an electronic controller 5, which is signal-connected to components such as the first drive mechanism 32, the second drive mechanism 29, the fourth drive unit 35, the entry detection device 38, the entry completion detection device 39, the exit detection device 40, and the exit completion detection device 41, facilitating automatic control of the entire cleaning process. In this embodiment, the electronic controller 5 is located at the lower part of the support below the feed section 7.

[0067] A second aspect of the present invention discloses a method for fully automatic cleaning using the aforementioned device:

[0068] Several trays 6 to be cleaned are sent to the tray unpacking machine 2, which separates them into individual trays 6 to be cleaned. The feeding section 7 delivers the trays 6 to the vicinity of the entrance of the cleaning section 1. After the entry detection device 38 detects the tray 6, the fourth drive 35 in the entrance airtight movable door 15 drives the entrance airtight movable gate 36 to open along the sealing guide groove 37. After the entrance airtight movable gate 36 is in place, the conveying roller 17 drives the tray 6 into the cleaning space composed of the upper cleaning roller 19, the lower cleaning roller 20, the side cleaning roller 21, and the blowing branch pipe 23. After the entry completion detection device 39 detects that the tray 6 has completely entered the cleaning section 1, the fourth drive 35 drives the entrance airtight movable gate. After the sealing guide groove 37 is closed and the inlet sealing movable gate 36 is closed in place, the compressed air automatic valve 22 opens, and the upper sweeping wheel 19, lower sweeping wheel 20 and side sweeping roller 21 rotate at high speed. At the same time, the negative pressure dust collector 14 starts to work, and the conveying roller 17 rotates forward and reverses at timed intervals. The tray 6 moves back and forth repeatedly in the cleaning space under the drive of the conveying roller 17 to perform one cleaning cycle. After one cleaning cycle is over, the tray 6 moves forward and is blocked by the baffle 34 of the blocker 26. The second drive mechanism 29 of the upper clamp 24 and the lower clamp 25 drives the first telescopic arm 30 to extend, and the first clamping part 31 of the upper clamp 24 and the lower clamp 25 clamps the tray. 6. The first drive mechanism 32 in the stopper 26 drives the rotating arm 33 and the baffle 34 to rotate 90 degrees counterclockwise into position. Then, the upper clamp 24 and the lower clamp 25 clamp the tray 6 and rotate it horizontally by 90 degrees into position. The second drive mechanism 29 in the upper clamp 24 and the lower clamp 25 drives the first telescopic arm 30 to retract, and the tray 6 falls back onto the conveyor roller 17. The conveyor roller 17 rotates in the opposite direction to send the tray 6 into the cleaning space. The conveyor roller 17 rotates forward and reverses at timed intervals. Under the drive of the conveyor roller 17, the tray 6 moves back and forth repeatedly in the cleaning space to perform secondary cleaning. After the secondary cleaning time is up, the tray 6 moves forward to the cleaning section 1. Near the exit sealed movable door 16, after the exit detection device 40 detects the tray 6, the compressed air automatic valve 22 closes, the upper cleaning roller 19, the lower cleaning roller 20 and the side cleaning roller 21 stop rotating, the negative pressure dust collector 14 stops working, the exit sealed movable door 16 opens, and the tray 6 moves out of the cleaning section 1. After the exit detection device 41 detects that the tray 6 has been completely moved out of the cleaning section 1, the tray 6 is sent to the tray assembly machine 3 by the delivery section 8. During the cleaning process, fine dust is collected by the negative pressure dust collector 14, and large particles of dust fall into the receiving hopper 11. The material in the receiving hopper 11 is discharged in a timed manner by opening the discharge valve 13. Almost all cleaning processes are controlled by the electronic controller 5.

[0069] In this embodiment, both the pallet unpacking machine 2 and the pallet assembly machine 3 are existing technologies. In other embodiments, the pallet unpacking machine 2 and the pallet assembly machine 3 may not be used, and manual unpacking and assembly may be employed instead.
