In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0052] The following is combined Figures 1-3 This invention describes a pallet cleaning system. The pallet cleaning system includes: a conveying device, a pallet cleaning device 100, a pallet surface detection device, and a controller.

[0053] like Figure 1As shown, the conveying device is equipped with multiple cleaning stations 200 for cleaning pallets, used to transport pallets between the multiple cleaning stations 200; a pallet cleaning device 100 is set on the corresponding cleaning station 200 for cleaning and defrosting the pallets; a pallet surface detection device is set on the corresponding cleaning station 200 for monitoring the pallet surface; a controller is electrically connected to the conveying device and the pallet cleaning device 100 respectively, and signal-connected to the pallet surface detection device, used to determine the frost condition and / or dryness condition of the pallet surface according to the pallet surface condition, and control the working status of the conveying device and the pallet cleaning device 100 according to the frost condition and / or dryness condition of the pallet surface.

[0054] Specifically, the conveying device can be a belt conveyor, which is used to transport pallets across multiple cleaning stations 200. During the conveying process, the pallet cleaning device 100 cleans and defrosts the pallets. A pallet surface detection device is installed at each cleaning station 200 of the conveying device to detect the surface condition of the pallets. A vision sensor can be used to take pictures of the pallet surface and transmit the pictures back to the controller. The controller uses the pallet pictures to determine the degree of frost and / or dryness of the surface, thereby controlling the working status of the conveying device and the pallet cleaning device 100 accordingly.

[0055] In this embodiment, the controller can store photos of clean trays. The tray photos obtained through the tray surface detection device are compared with these clean tray photos to determine the surface frost condition and / or dryness. It is understood that if there is frost on the tray surface, there will be a color difference between the photograph and the clean tray photo; this color difference can be used to determine the frost condition. Similarly, if there are water stains on the tray surface, there will be a difference in reflectivity between the photograph and the clean tray photo; this reflectivity can be used to determine the dryness. Of course, other factors related to the tray surface can also be used to determine the surface frost condition and / or dryness.

[0056] In addition to controlling the operating status of the pallet cleaning device 100 based on the frost and / or dryness of the pallet, the controller can also control the travel speed of the conveyor based on the frost and / or dryness of the pallet. Specifically, when the pallet is covered with thick frost, the movement speed of the pallet at the station of the pallet cleaning device 100 can be reduced to ensure thorough defrosting; conversely, the movement speed of the pallet at the station of the pallet cleaning device 100 can be increased. When the pallet has a lot of water stains, its drying time can be extended, i.e., the movement speed of the conveyor at the drying station (described in detail in the following embodiments) can be reduced; conversely, the drying time can be reduced, i.e., the movement speed of the conveyor at the drying station (described in detail in the following embodiments) can be increased. Of course, to ensure complete defrosting, the pallet cleaning device 100 can be installed at multiple cleaning stations 200.

[0057] This invention provides a pallet cleaning system, comprising: a conveying device, a pallet cleaning device 100, a pallet surface detection device, and a controller. The conveying device is used to convey pallets, the pallet cleaning device 100 is used to clean and defrost the pallets, the pallet surface detection device is used to monitor the pallet surface, and the controller is used to determine the frost condition and / or dryness condition of the pallet surface based on the surface condition, and to control the working state of the conveying device and the pallet cleaning device 100 based on the frost condition and / or dryness condition of the pallet surface. This pallet cleaning system can adjust the working state of the conveying device and the pallet cleaning device 100 according to the pallet surface condition, thereby ensuring complete pallet defrosting and improving production efficiency.

[0058] In one embodiment of the present invention, the pallet cleaning device 100 includes: a liquid storage device 2, a spraying device 3, and an air jetting device 4. The spraying device 3 is connected to the liquid storage device 2 and is used to spray the surface of the pallet; it is also used to air-dry the pallet surface after spraying. In this embodiment, the liquid storage device 2 stores liquid for cleaning the pallet, which can be a cleaning solution or clean water; different types of liquid can be selected according to the pallet cleaning standards. The spraying device 3 is connected to the liquid storage device 2 and sprays the liquid from the liquid storage device 2 to clean the surface of the pallet, thus defrosting the pallet. After spraying, the pallet needs to be dried using the air jetting device 4, completing the cleaning and defrosting operation. The spraying device 3 and the air jetting device 4 can be set at different cleaning stations 200, that is, the spraying device 3 and the air jetting device 4 are independently set; however, the spraying device 3 should be set at the station before the air jetting device 4, so that the pallet is first sprayed for defrosting and then air-dried.

[0059] In one embodiment of the present invention, multiple pallet surface detection devices are provided; the cleaning station 200 includes a defrosting station and a drying station arranged sequentially along the conveying direction of the conveying device. The pallet surface detection device, liquid storage device 2, and spray device 3 are located at the defrosting station; the pallet surface detection device and air spray device 4 are located at the drying station. In this embodiment, the conveying device has a defrosting station and a drying station arranged sequentially along the conveying direction. Each station can have one or more, depending on the defrosting requirements of the pallet. Each station has a different function: the defrosting station is used to defrost the pallet by spraying with the spray device 3; the drying station is used to thoroughly dry the pallet by spraying with the air spray device 4, thereby ensuring that there are no water stains on the pallet surface.

[0060] In one embodiment of the present invention, the pallet cleaning device 100 further includes: a support 1, a liquid storage device 2, a spray device 3, and an air jet device 4, all mounted on the support 1. In this embodiment, the support 1 serves as the supporting and mounting component of the entire device. The liquid storage device 2, the spray device 3, and the air jet device 4 are all mounted on the support 1. Through the integrated assembly of the support 1, it forms an independent device with pallet defrosting function. It can also be placed on an assembly line and used in conjunction with the product assembly line, eliminating the need to stop the machine to remove the pallets for individual cleaning, thereby improving product production efficiency. Of course, the pallet cleaning device 100 can also be correspondingly set at the defrosting station and the drying station, simply by controlling the corresponding device to start via a controller, mainly controlling the working status of the spray device 3 and the air jet device 4.

[0061] In one embodiment of the invention, the spraying device 3 includes a roller 31 and a first nozzle 32. The roller 31 is rotatably mounted on a support 1; the first nozzle 32 is mounted on the roller 31, and multiple first nozzles 32 are arranged along the axial and circumferential directions of the roller 31. Specifically, the roller 31 has multiple through holes along its axial and circumferential directions, and the first nozzles 32 are correspondingly installed on the through holes. The through holes allow communication between the roller 31 and the first nozzles 32. Liquid from the water storage device enters the interior of the roller 31, passes through the through holes, and is finally sprayed onto the tray surface through the first nozzles 32. In this embodiment, the spraying device 3 consists of a roller 31 and multiple first nozzles 32. The first nozzles 32 are mounted on the roller 31 and rotate synchronously with the roller 31, providing a 360° circumferential spraying effect, thereby defrosting the tray from multiple angles and positions, improving the defrosting effect. Furthermore, the first nozzles 32 are evenly arranged along the axial and circumferential directions of the roller 31, achieving uniform spraying and further improving the defrosting effect.

[0062] It should be understood that the first nozzle 32 in the above embodiment can spray the cleaning liquid at a certain pressure or in the form of a spray, which can further improve the defrosting effect. A high-pressure pump can be equipped on the spray device 3.

[0063] In one embodiment of the present invention, the support 1 includes a portal frame 11, with rollers 31 rotatably mounted on the portal frame 11, and multiple rollers 31 arranged sequentially through the portal frame 11 to form a portal structure. In this embodiment, the structural design of the portal frame 11 for mounting the rollers 31 determines the arrangement of the rollers 31. Multiple rollers 31 arranged to form a portal structure allow it to cross the conveyor line used for transporting pallets, thus matching the conveyor line. Specifically, the pallet passes under the portal structure formed by the rollers 31, and water is sprayed onto the pallet through multiple first nozzles 32 on the rollers 31 for defrosting. Preferably, as... Figure 2 and Figure 3As shown, three rollers 31 are provided, one on the left, one on the right and one on the top of the gantry frame 11, forming a gantry structure arrangement, which enables multi-directional and multi-angle spray defrosting of the pallet surface.

[0064] In one embodiment of the present invention, the support 1 further includes a connecting frame 12, which is connected to the portal frame 11. The connecting frame 12 has a first water channel 121 and a second water channel 122 inside. One end of the first water channel 121 is connected to the roller 31, and the other end is connected to the liquid storage device 2, for conveying the cleaning fluid in the liquid storage device 2 to the inside of the roller 31. One end of the second water channel 122 is connected to the roller 31, and the other end of the first water channel 121 is connected to the liquid storage device 2 via a water pump, for recovering the circulating water inside the roller 31. In this embodiment, the support 1 further includes a connecting frame 12, which has a first water channel 121 inside. The first water channel 121 connects the liquid storage device 2 and the roller 31, thereby conveying cleaning fluid into the inside of the roller 31 so that the cleaning fluid can be sprayed out using the first nozzle 32 to defrost the tray. Since roller 31 sprays the tray using the first nozzle 32, residual water may remain inside roller 31 during the spraying process. This residual water is then collected and stored in a water storage device via the second water passage 122, driven by a pump, thus collecting and circulating water and preventing waste. It should be understood that the water pump is restarted after the spraying device 3 has finished spraying to collect the residual water. Specifically, as... Figure 3 As shown ( Figure 3 (The middle arrow indicates the direction of the cleaning fluid flow). The first water path 121 is connected to the top of the roller 31, and the cleaning fluid is transported from top to bottom in the roller 31 and sprayed. The second water path 122 is connected to the bottom of the roller 31, and the cleaning fluid collected at the bottom of the roller 31 is recovered and returned to the liquid storage device 2.

[0065] It should be understood that the portal frame 11 in the above embodiments can also be replaced with an arched frame or the like, depending on the actual situation.

[0066] In one embodiment of the present invention, the tray cleaning device 100 further includes a heating device disposed between the first water channel 121 and the liquid storage device 2, for heating the cleaning liquid, and the heated cleaning liquid is more conducive to tray defrosting.

[0067] In one embodiment of the present invention, the jetting device 4 includes an air passage 41 and second nozzles 42. Multiple second nozzles 42 are sequentially arranged along the extension direction of the air passage 41 and are connected to the air passage 41 for jet drying of the tray surface after spraying. In this embodiment, the jetting device 4 consists of an air passage 41 and multiple second nozzles 42, which are arranged along the extension direction of the air passage 41 to dry the tray from multiple directions and angles. It is understood that the air inlet of the air passage 41 is connected to a blower / high-pressure pump, which blows air into the air passage 41 and sprays it out through the second nozzles 42 to dry the tray surface.

[0068] In one embodiment of the present invention, the air passage 41 is a gate-shaped air passage or an arch-shaped air passage. In this embodiment, the air passage 41 is formed into a gate-shaped air passage 41 or an arch-shaped air passage 41 according to its extension direction. Through the structural design of the air passage 41, it can cross the assembly line used for conveying pallets, thereby matching the assembly line for use.

[0069] In one embodiment of the present invention, the pallet cleaning device 100 further includes a moving device 5, which is mounted on the support 1. Preferably, the moving device 5 is in the form of rollers, with four rollers disposed at the bottom of the support 1. The rollers facilitate the movement of the pallet cleaning device 100 on the assembly line, thereby defrosting the corresponding pallets.

[0070] The present invention also provides a control method for a pallet cleaning system. The control method for the pallet cleaning system includes the following steps:

[0071] S1. Obtain information about the surface of the tray to determine the condition of the frost and / or dryness of the tray surface;

[0072] S2. Control the working status of the conveying device and the pallet cleaning device 100 according to the frost and / or dryness of the pallet surface.

[0073] Specifically, step S2 involves controlling the spraying state of the pallet cleaning device 100 and the conveying state of the conveying device according to the frost condition on the pallet surface, and / or controlling the air jet state of the pallet cleaning device 100 and the conveying state of the conveying device according to the dryness condition of the pallet surface.

[0074] Specifically, the control method of the pallet cleaning system provided in this embodiment is a control method of the controller in the pallet cleaning system. It receives image information of the pallet surface collected by the pallet surface detection device. The controller determines the frost condition and / or dryness condition of the pallet surface according to the pallet surface condition, and controls the spraying state and / or air jet state and conveying state of the pallet cleaning device 100 according to the frost condition and / or dryness condition of the pallet surface, thereby ensuring complete pallet defrosting.

[0075] The present invention provides a control method for a pallet cleaning system, which determines the frost condition and / or dryness condition of the pallet surface based on the pallet surface condition, and controls the working status of the conveying device and the pallet cleaning device based on the frost condition and / or dryness condition of the pallet surface, thereby achieving complete pallet defrosting and improving production efficiency.

[0076] In one embodiment of the present invention, the operation of the conveying device and the pallet cleaning device 100 in step S2 is controlled according to the frost condition and / or dryness condition of the pallet surface. Specifically, this includes controlling the number of sprays, spraying order, spraying frequency, spraying intensity, spraying water volume and spraying temperature of the multiple pallet cleaning devices 100 along the pallet conveying direction according to the frost condition of the pallet surface. Specifically, there are multiple defrosting stations, each equipped with a corresponding spray device 3. Depending on the frost condition on the tray surface, each spray device 3 can be opened, or the spray devices 3 can be opened at intervals. Since multiple rollers 31 and multiple first nozzles 32 are provided, the corresponding rollers 31 and first nozzles 32 can be controlled to spray in sequence. The top can be sprayed first, followed by the left and right sides, to improve defrosting efficiency. The starting frequency, spray intensity, spray water volume, and spray temperature of the spray device 3 can also be controlled according to the frost condition on the tray surface. If the frost is thick, the starting frequency, spray pressure, spray water volume, and spray temperature will be increased. Conversely, if the frost is thin, the starting frequency will be reduced and the spray pressure, spray water volume, and spray temperature will be increased accordingly.

[0077] In one embodiment of the present invention, the operation of the conveying device and the pallet cleaning device 100 in step S2 is controlled according to the frost and / or dryness of the pallet surface. Specifically, this includes controlling the number, sequence, frequency, and pressure of air jets from multiple pallet cleaning devices 100 along the pallet conveying direction based on the dryness of the pallet surface. Specifically, there are multiple drying stations, each equipped with a corresponding air jet device 4. Depending on the dryness of the pallet surface, each air jet device 4 can be opened, or opened at intervals. Since multiple second nozzles 42 are provided, the corresponding second nozzles 42 can be controlled to spray air sequentially, such as first spraying the top, then the left and right sides, to improve drying efficiency. The air jet frequency and pressure can also be controlled according to the dryness of the pallet surface. If there is more water, the air jet frequency and pressure are increased; conversely, if there is less water, the air jet frequency and pressure are decreased accordingly.
