Description

The present invention relates to an automatic steel plate cleaning system, an automatic steel plate cleaning device, and an automatic steel plate cleaning method which efficiently remove dirt and other adhering matter from the surface of steel plates used at construction sites in a dry manner without using water, allowing the cleaned steel plates to be reused, and which achieves space savings in terms of the arrangement and operation of the equipment.

At construction sites, etc., bad weather can cause the ground to become loose, making it difficult for vehicles to move.

Therefore, in order to facilitate the movement of dump trucks and other vehicles entering and leaving construction sites, it has traditionally been necessary to lay steel plates on the ground to facilitate passage, while keeping the vehicle paths free of soil and sand to reduce the amount of soil that adheres to the vehicles.

In addition, laying steel plates on the ground is widely used at construction sites to prevent sand adhering to vehicles from being carried onto public roads, and to protect the environment by preventing road pollution in the vicinity of the construction site.

The steel plates laid on the ground at a construction site are generally called steel plates (hereafter simply referred to as "steel plates").

Once construction is complete, the steel plates are collected and, after maintenance, are reused at other construction sites.

Steel plates recovered in this way often still have sand, mortar, etc. from the construction site that they were used at before they were recovered still attached to them, so they need to be cleaned before they can be reused.

To give an overview of conventional steel plate cleaning methods, the following methods 1. to 4. are used.

1. Use a scraper (spatula) to manually scrape off dirt from one side of the steel plate.
2. High-pressure water is sprayed from a nozzle onto the steel plate, blowing away any dirt or debris that may have adhered to it.
3. Use the above 1 and 2 together to wash off sand and other debris.
4. Use an automatic washer to wash off sand and other debris.

However, when cleaning steel plates using the above methods 1 to 4, the following problems arise:

In the case of 1. above, after one side of the steel plate is completed, it is necessary to turn it over.
b. If there are welding marks or other marks, it may damage the scraper.
c) Dirt around the wound is difficult to remove.
d) Removing dirt by hand takes a lot of time.

In the case of 2. above, when cleaning with high-pressure water, the power of the high-pressure water can be fully utilized only when the nozzle is focused on one point, and in order to clean a large area at once, it is necessary to use multiple nozzles spaced closely together or to spray while moving the nozzle.
b. When targeting a large area, multiple high-pressure pumps and nozzles are required, making the equipment expensive.
c. As in the case of 1. above, after one side is completed, it is necessary to turn it over.
d) Even if multiple high pressure pumps and nozzles are used, stubborn dirt does not necessarily come off.
e. Depending on the type of contamination, such as oil or freezing, high-temperature water may be required, so equipment to obtain high-temperature water is required.
f) When cleaning a steel plate in a horizontal position, the deposits remain on the steel plate, making it difficult to determine whether or not it has been cleaned.
In the case of a small number of nozzles, it takes time to remove the dirt, depending on the nozzle movement speed. Also, if the nozzle movement speed is too fast, the dirt is difficult to remove.
h After high-pressure cleaning, the polluted water needs to be purified.

In the case of 3. above, if there are even small snags such as welding marks on the steel plate to be cleaned, it is necessary to check in advance whether such marks exist or not.
b) Since this is done manually, hitting the marks can cause extreme fatigue and damage to the scraper.
c) If there are traces of welding, mortar, etc., it will be necessary to carefully scrape off the traces both before and after the traces several times with a spatula.
d After one side is finished, it is necessary to turn it over and clean the other side.
e) After cleaning, the polluted water needs to be purified.

In the case of 4. above, a) the steel plate is set in the cleaning machine and moved forward to be cleaned, but since it is cleaned in a horizontal position, the condition of the backside cannot be confirmed.
b. The product must be turned over to check the cleaning condition of the back side.
c) If the cleaning is not sufficient, it will be necessary to run the item through the cleaning machine again from the beginning or clean it by hand using a brush or similar.
d) The installation of the cleaning machine requires a large area three times the length of the steel plate.
e. Large amounts of water are required, and the polluted water will need to be treated for purification.

Next, we will provide an overview of prior technical documents 1 to 4.

Patent Document 1 discloses an iron plate cleaning device that includes a conveying roller device, a waiting station provided adjacent to the conveying start position of the conveying roller device, a receiving station provided adjacent to the conveying end position of the conveying roller device, a first moving means that adsorbs the iron plate surfaces one by one of the iron plate sheets that have been conveyed and stacked on the waiting station and moves them to the conveying start position of the conveying roller device and places them there, a cleaning machine that is positioned across the middle of the conveying direction of the conveying roller device and sprays cleaning liquid water simultaneously onto the front and back sides of the conveyed iron plate to remove dirt from the iron plate surface, and a second moving means that adsorbs the iron plate sheet that has been conveyed to the conveying end position of the conveying roller device after cleaning by the cleaning machine and places it on the receiving station.

However, the iron plate cleaning device of Patent Document 1 has a cleaning machine that sprays cleaning water simultaneously onto both sides of the horizontal iron plate to remove dirt from the surface of the iron plate, and like the above-mentioned case of 4., it has the problem that it is not possible to check the condition of the back side, a large amount of water is required, and purification treatment of polluted water is also required.

Patent Document 2 discloses an iron plate washing device that includes an iron plate feeding station that feeds in an iron plate placed on a frame, a pre-washing section that removes some of the soil from the fed iron plate, a washing station that washes the pre-washed iron plate, an iron plate removal station for removing the washed iron plate, a water tank that receives washing water, and a submersible pump section that draws up water from the water tank and sends the washing water to the washing station as high-pressure washing water.

However, in the case of the iron plate washing device of Patent Document 2, because a scraper is used for preliminary washing and washing water is used in the washing station, similar to the case of 1.4. described above, scratches on the scraper become an issue, and furthermore, a large amount of water is required, and post-treatment of polluted water is also required.

Patent document 3 discloses a steel plate cleaning device having a mounting frame on which a steel plate is placed, an upper pipe installed above the mounting frame and having a plurality of nozzles along the long side of the steel plate for spraying cleaning water toward the mounting frame, a lower pipe installed below the mounting frame and having a plurality of nozzles along the long side of the steel plate for spraying cleaning water toward the mounting frame, a control unit that controls the supply of cleaning water to the upper pipe and the lower pipe, and a pump unit that pressure-feeds cleaning water to the upper pipe and the lower pipe.

However, the steel plate cleaning device in Patent Document 3 employs a configuration in which cleaning water is sprayed from both above and below the mounting frame on which the steel plate is placed, and as in the case of 4. described above, this poses the problem of requiring a large amount of water and the need for post-treatment of the polluted water.

Patent document 4 discloses a steel plate cleaning device that includes a steel plate placement section having a placement surface on which multiple steel plates are placed, a cleaning nozzle that is placed above the steel plate placement section and sprays cleaning water in a direction along a first direction of the placement surface of the steel plate placement section and toward the placement surface, a cleaning nozzle horizontal section that moves the cleaning nozzle in a second direction intersecting with the direction along the first direction of the placement surface of the steel plate placement section, a cleaning nozzle vertical section that moves the cleaning nozzle along the first direction of the placement surface of the steel plate placement section, and a control unit that controls the operation of the cleaning nozzle vertical section and the cleaning nozzle horizontal section, and the control unit controls the operation of the cleaning nozzle vertical section and the cleaning nozzle horizontal section so as to repeat a horizontal movement that moves the cleaning nozzle along the second direction by the cleaning nozzle horizontal section, and a vertical movement that moves the cleaning nozzle along the first direction of the placement surface by the cleaning nozzle vertical section by a distance shorter than the length of the placement surface of the steel plate placement section in the first direction of the placement surface.

However, the cleaning device in Patent Document 4 is a water injection type in which cleaning water is sprayed from a cleaning nozzle onto one side of the steel plate, so as in the case of 2. above, it is necessary to turn the steel plate over after one side is cleaned, and as in the case of 4. above, it requires a large amount of water and also requires post-treatment of the polluted water, which is problematic.

The following describes in detail the automatic steel plate cleaning system, automatic steel plate cleaning device, and automatic steel plate cleaning method according to an embodiment of the present invention with reference to the drawings.

First, the automatic steel plate cleaning system 1 according to this embodiment will be described with reference to Figures 1 to 15 and Figures 38 to 47.

As shown in Figures 1 to 15, 44 and 45, the automatic steel plate cleaning system 1 of this embodiment has an automatic transport unit 3 consisting of a roller-driven configuration that transports steel plates 2 to be cleaned generated at construction sites, etc., and cleaned steel plates 2 in a planar manner and transports them out.

The automatic steel plate cleaning system 1 in this embodiment further includes an automatic steel plate cleaning device (cleaning machine ) 11 which uses a group of brushes to scrape and wipe off any adhering matter on the steel plate 2 in an upright (vertical) state and is arranged at the end of the automatic conveying unit 3 having a roller-driven configuration, and an automatic steel plate input unit (input machine) 4 which inputs the steel plate 2 to be cleaned, which is conveyed in a flat state by the automatic conveying unit 3, in an upright state into the automatic steel plate cleaning device 11, and returns the cleaned steel plate 2 which is pulled out in an upright state from the automatic steel plate cleaning device to a flat state and places it on the conveying surface of the automatic conveying unit 3.

As an example of transportation, for example, an automatic transport unit 3 having a roller-driven configuration has a number of transport rollers 5 arranged in a flat row on a transport roller support base 6, and is configured to drive the number of transport rollers 5 in forward and reverse rotation by a drive source not shown, and a steel plate transport line is formed on the upper surface of the number of transport rollers 5. The steel plate transport line is used to supply steel plates 2 to the automatic steel plate cleaning device 11, and the cleaned (washed) steel plates 2 are removed from the automatic steel plate cleaning device 11 and transported out.

Note that the illustrated example of the automatic transport unit 3 may or may not be a roller-driven type.

As shown in FIG. 44, the automatic steel plate feeder unit (feeder) 4 is equipped with a hydraulic cylinder 7 arranged on the installation surface near the automatic steel plate cleaning device 11, an extendable hydraulic jack 8 with one end supported by the hydraulic cylinder 7 and the other end facing the underside of the steel plate 2 transported by the steel plate transport line, and a steel plate erection assistance mechanism 9 arranged on the hydraulic cylinder 7. The hydraulic cylinder 7 moves the hydraulic jack 8 toward the automatic steel plate cleaning device 11, the steel plate erection assistance mechanism 9 assists in erecting the steel plate 2, and the hydraulic jack 2 extends, displacing the steel plate 2 from a horizontal state to an erect state, and feeding the steel plate 2 into the automatic steel plate cleaning device 11 in an erect state.

When the cleaned (washed) steel plate 2 is removed from the automatic steel plate cleaning device 11 by a steel plate delivery device (delivery machine) (not shown), the automatic steel plate feeder unit (feeder) 4 performs the reverse operation to that described above, returning the cleaned (washed) steel plate 2 from an upright position to a horizontal position and placing it on the steel plate conveying line of the automatic conveying unit 3.

According to the automatic steel plate cleaning system 1 of this embodiment, the uncleaned steel plate 2 is sent upright to the automatic steel plate cleaning device 11 by the automatic steel plate feeder unit 4, and cleaning is performed using a group of multiple brushes, the cleaned steel plate 2 is removed, and the cleaned steel plate 2 is transported to a stockyard (stock area) using the automatic transport unit 3, all of which are automated as shown in Figure 1.

A typical automated steel plate cleaning process involves inserting the object, moving it in a straight line over the cleaning machine, and after cleaning, stacking it or transporting it to a stock area using a transport machine.

For this reason, a cleaning space of at least three times the length of the steel plate is required.

In contrast, the automatic steel plate cleaning system 1 of this embodiment has the advantage that, if there is a space the length of the steel plate 2 that has already been cleaned using the configuration of this embodiment described above, it is possible to perform dry cleaning without using cleaning water, thereby saving space and eliminating the need for post-treatment of the cleaning water.

Next, the automatic steel plate cleaning system 1 according to this embodiment will be described in more detail with reference to Figures 1 to 15.

As shown in Figs. 2 to 4, the automatic steel plate cleaning system 1 according to this embodiment comprises a steel plate fixing frame 12 that is generally rectangular in shape and has a lower frame 12A protruding forward on the lower side, a pair of parallel rails 13 for moving the automatic steel plate cleaning device 11 that are laid along the length of the lower frame 12A, a pair of left and right holding units 14 that are incorporated into the left and right end sides of the lower frame 12A, for example, eight lift-up units 15 that are incorporated at predetermined intervals on the bottom of the lower frame 12A and arranged in a row, and a pair of lift-up units 15 that are respectively arranged at predetermined intervals on the upper part of the steel plate fixing frame 12. The apparatus includes an automatic steel plate cleaning unit 17 which is arranged on the lower frame 12A of the steel plate fixing frame 12 and on the right end side in FIG. 2 and which constitutes an automatic steel plate cleaning device 11 which moves while being guided by the pair of rails 13 and cleans (washes) the steel plate 2 fixed and held by the steel plate fixing frame 12 , an operation box 101 for an operator O which is arranged on the right end side of the steel plate fixing frame 12 in FIG. 2, and an electric control panel 19 which is assembled on the back side of the steel plate fixing frame 12 as shown in FIG. 3.

Next, we will explain each element that constitutes the automatic steel plate cleaning system 1 according to the present embodiment.

First, the left and right holding units 14 for the right end side of the steel plate 2 will be described in detail with reference to Figures 5 to 7.

The left and right holding units 14 are configured such that the holding lever 22 is rotatably supported at approximately the middle by a holding frame portion 21 fixedly arranged on the lower frame 12A of the steel plate fixing frame 12, and the holding lever 22 is displaced between the inclined position and the vertical position shown in FIG. 5 by an actuator 23 also fixedly arranged on the lower frame 12A of the steel plate fixing frame 12 and arranged in the vicinity of the holding frame portion 21, so that the right end surface of the steel plate 2 is fixedly held in place by the holding lever 22 in the vertical position.

In this case, the holding force can be, for example, 500 kgf.

The left and right holding units 14 for the left end side of the steel plate 2 use the above-mentioned configuration in a reversed left-right arrangement.

Next, with reference to Figures 8 to 11, we will explain the lift-up units 15, which are arranged in a row of, for example, eight units, and are installed at a predetermined interval on the bottom side of the lower frame 12A.

As shown in Figures 8 and 9, each lift-up unit 15 has a lower fixed plate 25 supported in a horizontal position by four support pillars 24 erected from the lower frame 12A to form a lower fixed frame portion 25A, two vertical guide rods 26 penetrating both sides of this lower fixed frame portion 25A so as to be movable vertically up and down, an actuator 27 is further incorporated so as to penetrate the center of the lower fixed plate 25, and a lift-up body 30 is arranged to be movable vertically up and down, which is integrated with an upper displacement plate 28 and a lift-up piece 29 that is V-shaped in side view and held by a support 29a arranged on the upper displacement plate 28 at the upper end of the actuator 27.

The upper ends of the two vertical guide rods 26 are connected to the underside of the upper displacement plate 28.

Furthermore, to protect the elements below the upper displacement plate 28 of the lift-up unit 15, a dust cover 31 is provided to prevent dirt from falling from the steel plate 2.

The lift-up piece 29 rises due to the lifting force of the actuator 27, so that the steel plate 2 (the lower end side of the steel plate 2) is lifted upward, as shown in Figures 10 and 11.

The lifting force in this case can be, for example, 470 kgf.

Next, with reference to Figures 2 to 4 and Figures 12 to 15, we will explain the upper holding units 16, which are arranged in a row of, for example, four units, and which are assembled at predetermined intervals on the upper part of the steel plate fixing frame 12 in the automatic steel plate cleaning system 1 according to this embodiment so that their positions can be adjusted.

The lower wire brush 51B of the lower wire brush unit 47B is swung along the lower surface (front and back) of the steel plate 2 by the swing motor 49 via the brush swing support 50 to scrape off any deposits adhering to these surfaces, and the actuator 53 of the pressure contact force adjustment mechanism 55 is configured to adjust the pressing force of the lower wire brush 51B of the lower wire brush unit 47B against the surface of the steel plate 2 via the first arm 50b and swing arm 50a.

The oscillation stroke of the oscillation motor 49 is ±20 mm, the oscillation frequency is 2.5 times/second, the oscillation force is 60 kgf, and the pressing force by the pressure contact force adjustment mechanism 55 is approximately 78 kgf.

These numerical examples also apply to the upper wire brush unit 47A and the middle wire brush unit 47C.

Next, the finishing brush unit (wiping brush unit) 48 and the finishing brush unit support part 71 will be described with reference to Figures 28 to 30.

The finishing brush unit 48 is arranged to sandwich both sides of the steel plate 2 with respect to the surface (front and back) of the steel plate 2, and functions to contact both sides of the steel plate 2 at a rear position (rear position in the traveling direction) relative to the upper wire brush unit 47A, etc., and wipe off any remaining deposits scraped off by the upper wire brush unit 47A, etc.

As shown in Figures 28 and 29, the finishing brush unit 48 is configured to support the finishing brush 75 by disposing a finishing brush support part 71 on the automatic cleaning device main body 41 side.

The finishing brush support part 71 is constructed by placing a base plate 76 on the side of the automatic cleaning device main body 41, erecting a pair of support posts 77 at a specified interval from both corners of the base plate 76, and fixing an upper plate 78 to each protruding end of the pair of support posts 77.

Furthermore, a finishing brush support plate 79 is arranged parallel to the side of the upper plate 78, and a pair of guide rods 80 are arranged at the outer positions of the pair of support posts 77, penetrating the upper plate 78 and with one protruding end fixed to one surface of the brush support plate 79. Also, an actuator 81 is arranged at the center of the upper plate 78, spanning this upper plate 78 and the brush support plate 79.

The finishing brush 75 is attached to the brush support plate 79, and the brush pieces 75a of the finishing brush 75 are brought into contact with the surface of the steel plate 2, so that the finishing brush 75 wipes off any remaining deposits that have been scraped off by the upper wire brush unit 47A, etc., as the automatic cleaning device main body 41 moves forward.

The actuator 81 can be operated to adjust the pressing force of the brush piece 75a of the finishing brush 75 against the surface of the steel plate 2 via the brush support plate 79. In this case, the pressing force of the brush piece 75a against the surface of the steel plate 2 can be set to approximately 75 kgf.

As shown in FIG. 30, the finishing brush unit support part 71 has an actuator 72 attached facing downward to the upper side of the automatic cleaning device main body 41, and the actuator 72 allows the support piece 73 that suspends and supports the finishing brush unit 48 to be adjusted up and down.

In other words, the finishing brush unit support portion 71 is configured to move the finishing brush unit 48 along each surface of the steel plate 2 in conjunction with the movement of the automatic cleaning device main body 41.

Next, we will discuss the specific configuration of the upper wire brush 51A of the upper wire brush unit 47A with reference to Figures 31 to 33.

As shown in Figures 31 to 33, this upper wire brush 51A is equipped with a brush section 82 in which a number of brush pieces (wire material) 83 are bundled and arranged in a straight line, and a mounting plate 84 in the shape of a square frame for holding the brush section 82 and allowing it to be set in the upper wire brush unit 47A, and which has a number of mounting holes 85 arranged in a row on its side.

The following are examples of the material, wire diameter, etc. of the brush piece (wire) 83:

The brush pieces (wire material) 83 are made of materials such as piano wire, steel, or stainless steel for springs.

The wire diameter of the brush piece (wire) 83 is approximately 0.3 mm to 0.7 mm.

Furthermore, an example of the length of the brush piece (wire material) 83 is about 30 to 40 mm.

The lower wire brush 51B has the same configuration as the upper wire brush 51A.

The same applies to the intermediate wire brush 51C of the intermediate wire brush unit 47C.

Next, the specific configuration of the finishing brush 75 of the finishing brush unit 48 will be described with reference to Figures 34 and 35.

As shown in Figures 34 and 35, the finishing brush 75 comprises a brush section 87 in which a number of brush pieces (e.g., made of synthetic resin material) 86 are bundled in a straight line and arranged in a row, and a mounting plate 90 that integrates a rectangular frame section 88 and a protrusion 89 to hold the brush section 87 and enable it to be set in the finishing brush unit 48.

The protruding piece 89 also has a number of mounting holes 91 arranged in a row.

The following are examples of the material, wire diameter, etc. of the brush pieces 86 of the finishing brush unit 48.

The brush pieces 86 of the finishing brush unit 48 are made of flexible synthetic resin, such as nylon brush pieces.

The wire diameter of the brush pieces 86 of the finishing brush unit 48 is approximately 0.3 to 1.0 mm.

Furthermore, the length (hair length) of the brush pieces 86 can be about 30 to 40 mm, similar to the length of the brush pieces 83, or can be slightly longer (like a cleaning broom).

Next, with reference to FIG. 36, we will explain the arrangement and behavior of each wire brush (upper wire brush 51A, lower wire brush 51B, and middle wire brush 51C) and the finishing brush 75 for each surface of the steel plate 2 in this embodiment.

In this embodiment, the upper wire brush 51A and the lower wire brush 51B are pressed against the upper and lower sides of each surface of the steel plate 2 in a vertically separated arrangement, and the middle wire brush 51C is pressed at a position intermediate the upper wire brush 51A and the lower wire brush 51B, and at the forward side in the direction of travel, and each is swung to scrape off deposits on each surface of the steel plate 2.

The finishing brush 75 is pressed against each surface of the steel plate 2 at a position rearward of the upper wire brush 51A and the lower wire brush 51B so as to be perpendicular to the direction of travel, and wipes off any remaining deposits scraped off by the wire brushes.

Figure 37 shows the arrangement of wire brush groups for a flat steel plate 2 in this embodiment, and Figure 38 shows the arrangement of wire brush groups for a curved steel plate 2 in this embodiment.

In the case of a flat steel plate 2, as shown in FIG. 37, the brush parts of the upper wire brush 51A, the lower wire brush 51B, and the middle wire brush 51C are pressed flush against each surface of the steel plate 2, and a scraping operation is performed by these.

The brush portion 85 of the finishing brush 75 is also pressed against each surface of the steel plate 2 to wipe off the dirt.

For curved steel plate 2, as shown in FIG. 38, the brush parts of the upper wire brush 51A, the lower wire brush 51B, and the middle wire brush 51C are pressed against the curved surfaces of the steel plate 2, and a scraping operation is performed using these.

The brush portion 85 of the finishing brush 75 is pressed against the curved surface of the steel plate 2 to wipe it off.

Next, the operation box 101 constituting the automatic steel plate cleaning system 1 according to this embodiment will be described with reference to Figures 39 to 41.

The operation box 101 is fixedly disposed on the right end side of the steel plate fixing frame 12 in FIG. 2, and is used by an operator O to perform various operations using a touch panel. The operation box 101 has a rectangular box-shaped main body 102.

The operation box body 102 incorporates a power button switch 103, an emergency stop button switch 104, a touch panel 105, and a lamp unit 106 for issuing operation signals and warnings.

The touch panel 105 is also configured to display mode buttons for automatic and manual operation based on the operating program, a reset button, and the like.

Next, the human intrusion detection unit 111 in the automatic steel plate cleaning system 1 according to this embodiment will be described with reference to Figures 42 and 43.

The human intrusion detection unit 111 detects whether or not an intruder O1 has entered the area of the steel plate fixing frame 12 or the automatic steel plate cleaning device 11 in the automatic steel plate cleaning system 1 according to this embodiment.

That is, detection posts 112, 113 are erected in opposing positions at both corners of the area of the steel plate fixing frame 12 and the automatic steel plate cleaning device 11, and two systems, for example infrared light emitting detection light emitting units 114 are arranged on the detection post 112, and two systems, for example infrared light emitting detection light receiving units 115 are arranged on the detection post 113, and it is configured to detect whether an intruder O1 has entered based on whether the light between the detection light emitting units 114 and the detection light receiving units 115 is blocked.

Figure 44 shows the operation of the automatic steel plate inserting unit 4 inserting the steel plate 2 into the automatic steel plate cleaning device 11 in an upright position.

The configuration of the automatic steel plate inserting unit 4 is as described above.

Next, the control system of the automatic steel plate cleaning system 1 according to this embodiment will be described with reference to FIG. 45.

The automatic steel plate cleaning system 1 according to this embodiment includes a program memory 121 that stores the operation program of the automatic steel plate cleaning system 1, and a control unit 122 that operates according to the operation program. The control unit 122 is configured to execute operation control of the automatic transport unit 3, the automatic steel plate inserting unit 4, the automatic steel plate cleaning device 11, the operation box 101, and the personal intrusion detection unit 111.

Next, the overall operational flow of the automatic steel plate cleaning system 1 according to this embodiment will be described with reference to FIG. 46.

In the automatic steel plate cleaning system 1 according to this embodiment, first, the operator O operates the power button switch 103 on the operation box main body 102 to turn on the power. If the automatic steel plate cleaning system 1 itself is ready to operate, it moves on to the next step. If it is not ready to operate, each element returns to its origin and waits for operation to be completed.

Next, if the operation preparation is complete, the operating program determines whether or not the automatic mode is selected, and if so, the steel plate 2 is set in the automatic steel plate inserting unit (insertion machine) 4.

Also, if the device is not in automatic mode, it will wait for the automatic push button switch to be turned on.

Next, it is determined whether the steel plate 2 has been set in the inserting machine, and if the steel plate has been set, the start button is turned on by the operation of operator O. If the steel plate has not been set, the machine waits for the steel plate to be set.

After the start button is turned on, the steel plate position is corrected as necessary.

Next, it is determined whether or not there is a steel plate 2 inside the cleaning machine. If there is no steel plate 2 inside the cleaning machine, the loading machine stands up and starts loading the steel plate 2 into the cleaning machine.

Also, if there is a steel plate 2 inside the cleaning machine, the process returns to the step of determining whether or not there is a steel plate 2 inside the cleaning machine.

After the steel plate 2 is inserted into the cleaning machine, the steel plate 2 is placed in the cleaning machine and clamped to a fixed state.

In other words, it determines whether the clamping of the steel plate 2 inside the cleaner is OK or not, and if the clamping is OK, it releases the steel plate 2 and then retreats.

If the clamp is not OK, a retry process is performed and the process returns to determining whether the clamp is OK or not.

After this, the cleaning machine starts cleaning (washing) the steel plate 2 held within the steel plate fixing frame.

That is, the wire brush unit 47 and the finishing brush unit 48 that make up the cleaning machine clean both sides of the steel plate 2, and when they reach the cleaning feed end of the steel plate 2, each element of the cleaning machine returns to its initial position.

Next, the removal machine (not shown) moves forward and clamps the cleaned steel plate 2.

Next, it is determined whether the clamping of the steel plate 2 by the removal machine is OK or not, and if the clamping is OK, the clamp of the steel plate 2 within the steel plate fixing frame is released.

If the clamping is not OK, a retry process is performed and the process returns to determining whether the clamping of steel plate 2 is OK or not.

Next, the removal machine retreats and moves on to processing the next workpiece, the steel plate 2, which has already been cleaned.

In other words, when processing the next workpiece, the cleaner returns after the removal machine has completed retreating, and after completing the return, it goes into a standby state waiting for the next workpiece, after which it transitions to the process of determining whether the steel plate has been set as described above.

On the other hand, when processing the steel plate 2 that has been cleaned, after the removal machine has completed retreating, the supply machine moves horizontally, and after the horizontal movement of the supply machine is completed, it is determined whether the primary waiting position for the cleaned steel plate 2 is vacant. If the primary waiting position is vacant, the dispensing process of the cleaned steel plate 2 is executed, and after the dispensing process is completed, the removal process of the cleaned steel plate 2 is executed, and upon removal being completed, the process returns to the step of determining whether the primary waiting position is vacant.

If the primary waiting position for the cleaned steel plate 2 is not empty in the above-mentioned process, the cleaned steel plate 2 will be placed in a waiting state for removal.

The removal of the above-mentioned cleaned steel plate 2 corresponds to the circled number 3 in the operation flow diagram 47 regarding the transfer process of the cleaned steel plate to the stockyard, which will be described later.

Next, with reference to Figure 47, we will explain the operation flow for the process of transferring cleaned steel plate 2 to the stockyard, although this will be partially overlapped.

When the operator O operates the power button switch 103 on the operation box body 102 to turn on the power, if the automatic steel plate cleaning system 1 itself is ready to operate, it moves on to the next step, but if it is not, each element returns to its origin and waits for operation preparation to be completed.

Next, if preparations for operation are complete, the operating program determines whether or not the automatic mode is selected, and if so, the system determines whether or not the cleaner is waiting to remove the steel plate 2, and if so, the steel plate 2 is removed from the cleaner (circled number 3 in Figure 47).

When the cleaned steel plate 2 is removed from the cleaning machine, the cleaned steel plate 2 is transferred to the stockyard, the transfer is completed, and the process returns to the step of determining whether the cleaning machine has removed the steel plate 2 and is waiting.

On the other hand, if the cleaning machine is not waiting to remove the steel plate 2, the system 1 further determines whether the cleaning machine is waiting to set the steel plate, and if so, transfers the uncleaned steel plate 2 to the stockyard, then removes the uncleaned steel plate 2 and transfers it to the input machine, and after the transfer is complete, the system returns to the step of determining whether the steel plate 2 is waiting to be removed.

Then, it is determined whether the cleaning machine is waiting for the steel plate to be set, and if it is not, it returns to the step of determining whether the steel plate 2 is waiting to be removed.

Next, we will provide a general explanation of the automatic steel plate cleaning device 11 in this embodiment.

The automatic steel plate cleaning device 11 of this embodiment is configured to scrape off dirt by swinging the upper wire brush 51A of the upper wire brush unit 47A, the lower wire brush 51B of the lower wire brush unit 47B, and the middle wire brush 51C of the middle wire brush unit 47C, and to wipe off dirt by moving the finishing brush 75 of the finishing brush unit 48 left and right, which allows for space saving overall.

In addition, since the brush groups are not rotated to remove dirt, damage to each brush group is kept to a minimum.

Furthermore, the pressing force of each brush group against the steel plate 2 can be adjusted depending on the degree of dirt on the steel plate 2.

Furthermore, each brush group is configured to be able to move back and forth along the surface of the steel plate 2, so when the surface of the steel plate 2 is particularly dirty, the speed of each brush group can be changed according to the situation and they can be moved back and forth multiple times.

The automatic steel plate cleaning device 11 according to this embodiment cleans the steel plate 2 in an upright position (vertical or nearly vertical), so the condition of the front and back sides of the steel plate 2 can be checked at a glance, and there is also the advantage that no polluted water is generated because no water is used.

Furthermore, the soil and sand scraped off the surface of the steel plate 2 can be automatically transported to the outside using a comparer or the like.

Next, relevant matters regarding the automatic steel plate cleaning system 1, automatic steel plate cleaning device 11, and automatic steel plate cleaning method of this embodiment will be added.

In the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, the steel plate 2 is fixed vertically or diagonally, and the brush group is moved to simultaneously clean both the front and back sides in a dry manner without using water.

The automatic steel plate cleaning device 11 may be operated while spraying water.

In this embodiment, the scraping brushes of the brush group are oscillated and the wiping brush is moved linearly, but they may also be moved only in the vertical direction or only in the horizontal direction (left and right).

The scraping brush group does not necessarily have to be made of metal, and a composite material including the above materials can be used.

The wiping brush can also be made of a composite material that includes the above materials.

Furthermore, the scraping brush group may be divided into any number of configurations other than those already described.

In the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, when changing (replacing) the wire diameter and bristle length of the brushes in each brush group, it is possible to find the optimum product by replacing with various brushes depending on the degree of dirt on the steel plate 2.

In other words, we conduct repeated experiments to verify the results and operate the actual product.

Please note that the stiffness of the brush varies greatly depending on the wire diameter and bristle length.

In addition, with regard to the cleaning (washing) time of the steel plate 2 in the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, it should be noted that this time varies depending on the degree of dirt on the steel plate 2 by changing the conditions such as the moving speed, oscillating speed, pressing force, and number of reciprocating movements of the brush group.

The automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment are dry types that do not use water, and can operate even when the steel plate contains a lot of moisture. However, it should be noted that cleaning of the brush group may be necessary if there is too much clayey soil attached to the brush group.
