[0001] The invention belongs to the technical field of three-dimensional storage systems and relates to large-channel heavy-load cleaning equipment and an operation method. Background Art

[0002] In the three-dimensional storage system, old industrial parts are often returned to the three-dimensional warehouse for storage after being repaired. Dust and debris are often attached to the surface of the old parts. The existing method uses manual cleaning and then relies on manually controlled forklifts to transfer them to shelves for storage. As a result, the existing manual cleaning method has the problems of low efficiency and waste of water and human resources. Summary of the invention

[0003] The purpose of the present invention is to provide a large channel heavy-load cleaning device and an operation method to solve the problems of low efficiency and waste of human resources in existing manual cleaning methods.

[0004] In order to achieve the above-mentioned object, the basic scheme of the present invention is: a large channel heavy-load cleaning device, including a conveying roller, an inlet sensor, a spray unit, a first in-place detection sensor, a rotating device, a blowing unit, a second in-place detection sensor and an outlet sensor;

[0005] The inlet sensor is arranged at the inlet of the conveying roller, the spray unit is arranged on the peripheral side of the conveying roller and located at the rear side of the inlet sensor, and the output end of the inlet sensor is connected to the start end of the spray unit;

[0006] The first arrival detection sensor is arranged on the side of the conveying roller and at the rear side of the spray unit, and the first arrival detection sensor is used to detect whether the cleaned goods have reached the cleaning position;

[0007] The rotating device is arranged above the conveying roller, the edge of the rotating device is arranged downward and tilted outward, the conveying roller drives the cleaned goods to move onto the rotating device, the output end of the first in-place detection sensor is connected to the starting end of the rotating device and the stopping end of the conveying roller, and the starting end of the rotating device is connected to a timer;

[0008] The blowing unit is arranged at the rear side of the first in-place detection sensor and at the side of the conveying roller, the second in-place detection sensor is located at the rear side of the rotating device, and is used to detect whether the washed goods have reached the air-drying position, the output end of the timer is connected to the starting end of the conveying roller, the stopping end of the spray unit and the starting end of the second in-place detection sensor, and the output end of the second in-place detection sensor is connected to the starting end of the blowing unit;

[0009] The outlet sensor is arranged at the rear end of the conveying roller, and the output end of the outlet sensor is connected to the stop end of the blowing unit.

[0010] The working principle and beneficial effects of this basic solution are: this technical solution places the goods on the conveyor roller, and the forward conveying of the goods triggers the entrance sensor, and the entrance sensor triggers the spray unit to start working after signal processing, and the spray unit continuously sprays and cleans the goods moved to the corresponding position.

[0011] The continued movement of the goods will trigger the first arrival detection sensor. After the first arrival detection sensor detects that the goods are in place, it outputs a control signal to the stop end of the conveyor roller, and the conveyor roller stops running.

[0012] When the conveying roller stops working, the first in-position detection sensor outputs a control signal to the start end of the rotating device, starts the rotating device, controls the rotation of the goods so that the spray unit cleans the circumference of the goods. The rotation time is controlled by the timer, which indirectly meets the set number of rotations. When the rotation time is reached, the timer outputs a corresponding control signal to the start end of the conveying roller, the stop end of the spray unit and the start end of the second in-position detection sensor, then the spray unit is stopped, the conveying roller is started to run, and the goods continue to move forward to trigger the second in-position detection sensor.

[0013] After the second arrival detection sensor is triggered, it outputs a signal to the blowing unit. The blowing unit starts to run and continuously outputs high-pressure air for drying. The goods continue to move forward and trigger the exit sensor, and the blowing unit stops running.

[0014] Furthermore, it also includes an entrance weighing and conveying module and an appearance detection module;

[0015] The inlet weighing and conveying module is arranged at the head end of the conveying roller and is used to collect the weight of the cleaned goods;

[0016] The appearance detection module is arranged at the rear side of the entrance weighing and conveying module, and is used to collect the appearance image of the cleaned goods and compare it with the preset image to determine whether the cleaned goods meet the requirements. The starting end of the entrance sensor is connected to the output end of the appearance detection module.

[0017] The goods are placed on the entrance weighing and conveying module for weight detection and code scanning and recording. The conveying rollers pass the goods through the appearance detection module for appearance detection. If the appearance is unqualified, an alarm will be issued and the goods will be returned to the starting end for processing.

[0018] Furthermore, it also includes a water collection and recovery box, which is arranged below the conveying roller.

[0019] The cleaned sewage is collected in a water collection tank for recycling and filtration before reuse, thus saving water resources.

[0020] Furthermore, it also includes an outer shell, a part of the conveying roller, a spray unit, a first in-place detection sensor, a rotating device, a blowing unit, and a second in-place detection sensor are all placed in the outer shell.

[0021] The outer shell is provided to protect each device, and also to prevent sewage from splashing onto the outside of the outer shell during cleaning, thereby preventing environmental pollution.

[0022] Further, the spray unit includes a booster pump, a frame and a plurality of spray heads;

[0023] The booster pump is installed on the side of the conveying roller, the bottom of the frame is arranged on both sides of the conveying roller, and a frame hole is formed between the frame and the conveying roller for the cleaned goods to pass through;

[0024] The plurality of nozzles are arranged on the frame and face the conveying roller, and the booster pump is connected with the nozzles.

[0025] The spray unit has a simple structure and is easy to use.

[0026] The present invention also provides an operation method based on the large channel heavy-load cleaning equipment of the present invention, comprising the following steps:

[0027] Place the cleaned goods at the head end of the conveyor roller for weight detection and code scanning.

[0028] The conveyor roller drives the cleaned goods to move, collects the appearance image of the goods, and compares the image with the preset image. If the image does not match the preset image, the appearance of the cleaned goods is judged to be unqualified, an alarm signal is output and the image is returned to the starting end for processing;

[0029] If the image matches the preset image, the conveyor roller runs to convey the cleaned goods forward to trigger the entrance sensor, and the entrance sensor triggers the booster pump to start working after signal processing, and the spray unit continues to spray and clean the cleaned goods;

[0030] The cleaned goods continue to move forward and trigger the first arrival detection sensor. After the first arrival detection sensor detects that the cleaned goods have reached the cleaning position, that is, the cleaned goods are located on the rotating device, the conveying roller stops running;

[0031] The rotating device starts, driving the cleaned goods on the rotating device to rotate, and the spray unit can clean the whole body of the cleaned goods. After the rotating device rotates a set number of circles, it stops running, the booster pump also stops running, the conveying roller starts running, and the goods continue to move forward, triggering the second arrival detection sensor;

[0032] The blowing unit starts and continuously outputs high-pressure air to the cleaned goods on the conveyor roller for drying. The conveyor roller continues to run, and the cleaned goods continue to move forward to trigger the exit sensor, and the blowing unit stops running.

[0033] The method can achieve the steps of cleaning, drying, and conveying without manual labor, thereby reducing the cost of human resources and the cost of purchasing transfer machinery and improving production efficiency.

[0034] Furthermore, based on the appearance image of the cleaned goods, the surface contamination degree W is detected, which is:

[0035]

[0036] According to the surface contamination degree of the goods being cleaned, the spraying pressure P, spraying particle size D and spraying time T of the spray unit are controlled, specifically:

[0037] P(W)=P0(1+W γ1 ) -β1W

[0038] D(W)=D0(1+W γ2 )(1-e -β2W )

[0039]

[0040] Among them, P0 is the basic spraying pressure, D0 is the basic spraying intensity, T0 is the basic spraying time, W0 is the pollution level threshold (for example, 20%), γ1 and γ2 are exponential coefficients (between 1 and 3), which respectively express the influence of the pollution level on the pressure and particle size, and β1 and β2 are attenuation factors, which are between 0 and 1.

[0041] Adjust the spray pressure of the spray unit to optimize the cleaning effect.

[0042] Furthermore, the cleaned goods are cleaned in two stages, with water spraying evenly in the first stage;

[0043] The second stage: Divide the surface area of ​​the cleaned goods, check the pollution value of each surface area of ​​the cleaned goods, that is, the degree of surface pollution, and sort them from large to small, and mark the corresponding surface area ranked before the preset value as a heavily polluted area;

[0044] The spray unit is controlled to spray cleaning fluid and then water to the heavily polluted areas.

[0045] The cleaned goods are cleaned in two stages, and the heavily polluted areas are cleaned specifically to ensure the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
