Description

[Technical field]

[0001] The present invention relates to Construction sites This method efficiently removes dirt and sand from the surface of steel plates used in the dry process without using water. The cleaned steel plates are reused, and space savings have been achieved for the layout and operation of the equipment. The present invention relates to an automatic steel plate cleaning system, an automatic steel plate cleaning device, and an automatic steel plate cleaning method. [Background technology]

[0002] At construction sites, etc., the ground may become loose due to weather conditions, making it difficult for vehicles to move.

[0003] Therefore, in the past, in order to facilitate the movement of vehicles such as dump trucks entering and leaving construction sites, steel plates have been laid on the ground to facilitate passage, and there has been a demand for keeping the vehicle paths free of soil and sand to reduce the amount of soil adhering to the vehicles.

[0004] 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 also to protect the environment by preventing road pollution in the vicinity of the construction site.

[0005] Steel plates laid on the ground at a construction site are generally called steel plates (hereinafter simply referred to as "steel plates").

[0006] Once construction is completed, the steel plates are collected and, after maintenance, are reused at other construction sites.

[0007] Steel plates recovered in this manner often still have sand, mortar, etc., remaining on them from the construction site prior to recovery, and therefore require cleaning before they can be reused.

[0008] To give an overview of conventional steel plate cleaning means, the following means 1. to 4. are adopted.

[0009] 1. Dirt is manually scraped off from one side of the steel plate using a scraper (spatula). 2. High-pressure water is sprayed from a nozzle onto the steel plate, blowing away any dirt or deposits. 3. Use steps 1 and 2 above together to wash off sand and other debris. 4. Use an automatic washer to wash off sand and other debris.

[0010] However, the above-mentioned steel plate cleaning methods 1 to 4 involve the following problems.

[0011] In the case of 1 above a After one side of the steel plate is completed, it must be turned over. b) If there are welding marks or other defects, they may damage the scraper. c Dirt around the wound is difficult to remove. d Removing dirt manually takes a lot of time.

[0012] In the case of 2 above When cleaning with high-pressure water, the power of the high-pressure water can only be exerted when the nozzle is concentrated at one point. 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 1 above, after one side is completed, it is necessary to flip 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 it has been cleaned or not. g In the case of a small number of nozzles, it takes time to remove dirt, depending on the nozzle movement speed. Also, if the nozzle movement speed is too fast, dirt is difficult to remove. h After high-pressure cleaning, the polluted water needs to be purified.

[0013] In the case of 3 above a) 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 must be turned over and the other side cleaned. e) After cleaning, the polluted water will need to be purified.

[0014] In the case of 4 above a The steel plate is set in the cleaning machine and moved forward to be cleaned, but because it is cleaned in a horizontal position, the condition of the back side cannot be confirmed. b Must be turned over to view backside cleaning. c) If cleaning is not sufficient, the item must be put through the cleaning machine again from the beginning or cleaned 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.

[0015] Next, prior art documents 1 to 4 will be outlined.

[0016] Patent document 1 discloses an iron plate cleaning device that includes a transport roller device, a waiting station located adjacent to the transport start position of the transport roller device, a receiving station located adjacent to the transport end position of the transport roller device, a first moving means that adsorbs each of the iron plate sheets that have been transported and stacked flat on the waiting station onto the surface of the iron plate and moves it to the transport start position of the transport roller device and places it there, a cleaning machine that is positioned across the middle of the transport direction of the transport roller device and sprays cleaning water simultaneously onto the front and back sides of the transported iron plate to remove dirt from the surface of the iron plate, and a second moving means that adsorbs the iron plate that has been cleaned by the cleaning machine and transported to the transport end position of the transport roller device and places it on the receiving station.

[0017] However, the iron plate cleaning device of Patent Document 1 is configured with a cleaning machine that sprays cleaning water simultaneously onto the front and back sides of the horizontal iron plate to remove dirt from the surface of the iron plate. As with the case of 4. mentioned above, this 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.

[0018] Patent document 2 discloses an iron plate cleaning device comprising an iron plate feeding station for feeding an iron plate placed on a frame, a pre-cleaning section for removing some of the soil from the fed iron plate, a cleaning station for cleaning the pre-cleaned iron plate, an iron plate removal station for removing the cleaned iron plate, a water tank for receiving cleaning water, and a submersible pump section for pumping up water from the water tank and sending the cleaning water to the cleaning station as high-pressure cleaning water.

[0019] However, in the case of the iron plate washing device of Patent Document 2, a scraper is used for preliminary washing, and washing water is used in the washing station. As a result, 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.

[0020] Patent document 3 discloses a steel plate cleaning device having a mounting frame on which a steel plate is placed, an upper piping 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 piping 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 piping and lower piping, and a pump unit that pressure-feeds cleaning water to the upper piping and lower piping.

[0021] However, the steel plate cleaning device of 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, which, as in the case of 4. described above, requires a large amount of water and also entails the problem of the need for post-treatment of the polluted water.

[0022] Patent Document 4 discloses a steel plate cleaning device comprising: a steel plate positioning section having a placement surface on which a plurality of steel plates are placed; a cleaning nozzle arranged above the steel plate positioning section for spraying cleaning water in a direction along a first direction of the placement surface of the steel plate positioning section and in a direction toward the placement surface; a cleaning nozzle traversing section for moving the cleaning nozzle in a second direction intersecting the direction along the first direction of the placement surface of the steel plate positioning section; a cleaning nozzle vertical section for moving the cleaning nozzle along the first direction of the placement surface of the steel plate positioning section; and a control unit for controlling operation of the cleaning nozzle vertical section and the cleaning nozzle traversing section, wherein the control unit controls operation of the cleaning nozzle vertical section and the cleaning nozzle traversing section so as to repeat a traversal movement in which the cleaning nozzle traversing section moves the cleaning nozzle along the second direction, and a vertical movement in which the cleaning nozzle vertical section moves the cleaning nozzle along the first direction of the placement surface by a distance shorter than the length of the placement surface of the steel plate positioning section in the first direction of the placement surface.

[0023] However, the cleaning equipment of Patent Document 4 is of a water injection type in which cleaning water is sprayed from a cleaning nozzle onto one side of the steel plate, and therefore, as in the case of 2. described above, it is necessary to turn the steel plate over after one side has been cleaned. Furthermore, as in the case of 4. described above, it requires a large amount of water and also requires post-treatment of the polluted water. This is problematic.

EXAMPLES

[0039] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic steel plate cleaning system, an automatic steel plate cleaning device, and an automatic steel plate cleaning method according to embodiments of the present invention will be described in detail below with reference to the drawings.

[0040] First, an automatic steel plate cleaning system 1 according to this embodiment will be described with reference to FIGS. 1 to 15 and 38 to 47. FIG.

[0041] As shown in Figs. 1 to 15, 44 and 45, the automatic steel plate cleaning system 1 according to this embodiment performs flat feeding and removal of steel plates 2 to be cleaned generated at construction sites and the like. Roller drive configuration The automatic transport unit 3 comprises:

[0042] The automatic steel plate cleaning system 1 according to the present embodiment further comprises the steps of: Roller drive configurationThe automatic steel plate cleaning device (cleaning machine) 11 is arranged at the end of the automatic transport unit 3 consisting of a brush and a plate feeder unit (feeder) 4 which feeds the steel plate 2 to be cleaned, which is transported in a flat state by the automatic transport 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 transport surface of the automatic transport unit 3.

[0043] As an example of transportation, Roller drive configuration The automatic conveying unit 3 consisting of the above is configured such that a large number of conveying rollers 5 are arranged in a flat row on a conveying roller support base 6, and the large number of conveying rollers 5 are driven to rotate in forward and reverse directions by a driving source not shown, and a steel plate conveying line is formed on the upper surface of the large number of conveying rollers 5. The steel plate conveying 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.

[0044] It should be noted that the illustrated example of the automatic transport unit 3 may or may not be of a roller drive type.

[0045] As shown in Figure 44, the automatic steel plate feeding unit (feeding machine) 4 comprises a hydraulic cylinder 7 arranged on an 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 conveying line, and a steel plate standing assist mechanism 9 arranged on the hydraulic cylinder 7, and is configured so that the steel plate 2 is displaced from a horizontal state to an upright state by the movement of the hydraulic jack 8 toward the automatic steel plate cleaning device 11 by the hydraulic cylinder 7, the standing assist action of the steel plate 2 by the steel plate standing assist mechanism 9, and the extension action of the hydraulic jack 2, so that the steel plate 2 is fed into the automatic steel plate cleaning device 11 in an upright state.

[0046] In addition, when the cleaned (washed) steel plate 2 is removed and transported from the automatic steel plate cleaning device 11 by a steel plate delivery device (delivery machine) (not shown), the automatic steel plate feeding unit (feeding machine) 4 performs the reverse operation to that described above, returning the cleaned (washed) steel plate 2 from an upright state to a horizontal state and placing it on the steel plate conveying line of the automatic conveying unit 3.

[0047] In the automatic steel plate cleaning system 1 according to this embodiment, an uncleaned steel plate 2 is fed in an upright state by an automatic steel plate feeding unit 4 to an automatic steel plate cleaning device 11, where it is cleaned by 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 FIG.

[0048] A typical automatic steel plate cleaning process involves inserting the object into the cleaning machine, moving it in a straight line over the cleaning machine, and then after cleaning, stacking it or transporting it to a stock area by a transport machine.

[0049] For this reason, a cleaning space that is at least three times the length of the steel plate is required.

[0050] In contrast, according to the automatic steel plate cleaning system 1 of this embodiment, if there is a space the length of the steel plate 2 that has already been cleaned by the configuration of this embodiment described above, cleaning can be performed in a dry manner without using cleaning water, which has the advantages of saving space and not requiring post-treatment of the cleaning water.

[0144] Next, the overall operation flow of the steel plate automatic cleaning system 1 according to this embodiment will be described with reference to FIG.

[0145] In the automatic steel plate cleaning system 1 of this embodiment, first, an operator O operates the power button switch 103 of 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, but if it is not ready to operate, each element returns to its origin and waits for operation preparation to be completed.

[0146] Next, if the operation preparation is complete, the operation program judges whether or not the automatic mode is selected. If the automatic mode is selected, the steel plate 2 is set in the automatic steel plate inserting unit (inserting unit) 4.

[0147] If the automatic mode is not selected, the automatic push button switch is turned on.

[0148] Next, it is determined whether or not the setting of the steel plates 2 in the inserting machine has been completed, and if the setting of the steel plates has been completed, the start button is turned on by the operation of the operator O. If the setting of the steel plates has not been completed, the process waits for the steel plates to be set.

[0149] After the start button is turned on, the steel plate position is corrected as necessary.

[0150] 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 inserting machine performs an upright operation and inserts the steel plate 2 into the cleaning machine by the inserting machine.

[0151] Also, if the steel plate 2 is present inside the cleaning machine, the process returns to the step of determining whether or not the steel plate 2 is present inside the cleaning machine.

[0152] After the operation of inserting the steel plate 2 into the cleaning machine has been performed, the steel plate 2 is placed in the cleaning machine and clamped to be in a fixed state.

[0153] That is, it is determined whether or not the clamping of the steel plate 2 inside the cleaner is OK, and if the clamping is OK, the steel plate 2 is released and then the cleaner moves backward.

[0154] If the clamp is not OK, a retry process is executed, and the process returns to the determination of whether the clamp is OK or not.

[0155] Thereafter, the cleaning (washing) by the cleaning machine of the steel plate 2 held within the steel plate fixing frame is started.

[0156] That is, both sides of the steel plate 2 are cleaned by the operation of the wire brush unit 47 and the finishing brush unit 48 that constitute the cleaning machine, and when the cleaning feed end of the steel plate 2 is reached, each element of the cleaning machine returns to its initial position.

[0157] Next, an extractor (not shown) moves forward and clamps the cleaned steel plate 2 .

[0158] Next, it is determined whether or not the clamping of the steel plate 2 by the take-out machine is OK, and if the clamping is OK, the clamp of the steel plate 2 within the steel plate fixing frame is released.

[0159] If the clamping is not OK, a retry process is executed, and the process returns to the determination of whether the clamping of the steel plate 2 is OK or not.

[0160] Next, the removal machine retreats and moves on to processing the next workpiece, the steel plate 2 which has already been cleaned.

[0161] That is, in processing the next workpiece, after the removal machine has completed retreating, the cleaner returns, and after completing the return, the machine goes into a standby state waiting for the next workpiece, after which the process proceeds to the previously described process of determining whether or not the steel plate has been set.

[0162] On the other hand, in processing the steel plate 2 which 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 or not 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 or not the primary waiting position is vacant.

[0163] If the primary standby position for the cleaned steel plate 2 is not vacant in the above-mentioned process, the cleaning process is stopped and the cleaned steel plate 2 is placed in standby state for removal.

[0164] The above-mentioned removal of the cleaned steel plate 2 corresponds to the circled number 3 in the operation flow diagram 47 relating to the transfer process of the cleaned steel plate to a stockyard, which will be described later.

[0165] Next, with reference to FIG. 47, although there is some overlap, an operational flow regarding the transfer process of the cleaned steel plate 2 to the stockyard will be described.

[0166] When the operator O operates the power button switch 103 of 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, but if it is not ready to operate, each element returns to its origin and waits for operation preparation to be completed.

[0167] Next, if the operation preparation is complete, the operating program determines whether or not the automatic mode is selected, and if the automatic mode is selected, the system determines whether or not the cleaning machine is waiting to remove the steel plate 2, and if it is waiting to remove the steel plate 2, the steel plate 2 is removed from the cleaning machine (circled number 3 in Figure 47).

[0168] When the cleaned steel plate 2 is removed from the cleaning machine, the cleaned steel plate 2 is transferred to a stockyard, the transfer is completed, and the process returns to the step of checking whether the cleaning machine has removed the steel plate 2 and is on standby.

[0169] On the other hand, if the cleaning machine is not waiting to remove the steel plate 2, the system 1 further judges whether or not the cleaning machine is waiting to set a steel plate. If the cleaning machine is waiting to set a steel plate, the uncleaned steel plate 2 is transferred to a stockyard, and then the uncleaned steel plate 2 is removed and transferred to the input machine. After the transfer is completed, the system returns to the step of determining whether or not the cleaning machine is waiting to remove the steel plate 2.

[0170] Then, it is judged whether or not the cleaning machine is waiting for the steel plate to be set, and if the cleaning machine is not waiting for the steel plate to be set, the process returns to the step of judging whether or not the cleaning machine is waiting for the steel plate 2 to be removed.

[0171] Next, the automatic steel plate cleaning device 11 according to this embodiment will be generally described.

[0172] According to the automatic steel plate cleaning device 11 of this embodiment, scraping is performed 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 wiping is performed by moving the finishing brush 75 of the finishing brush unit 48 left and right, so that overall space can be saved.

[0173] Furthermore, since the brush groups are not rotated to remove dirt, damage to each brush group is kept to a minimum.

[0174] 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.

[0175] Furthermore, since each brush group is configured to be able to move back and forth along the surface of the steel plate 2, when the surface of the steel plate 2 is particularly dirty, the brush groups can be moved back and forth multiple times while changing the speed according to the situation.

[0176] According to the automatic steel plate cleaning device 11 of this embodiment, the steel plate 2 is cleaned in an upright state (vertical or approximately vertical state), so that the condition of the front and back sides of the steel plate 2 can be confirmed at a glance, and there is also the advantage that no polluted water is generated because no water is used.

[0177] Furthermore, the soil and sand scraped off the surface of the steel plate 2 can be automatically transported to the outside using a conveyor or the like.

[0178] Next, relevant matters regarding the automatic steel plate cleaning system 1, the automatic steel plate cleaning device 11, and the automatic steel plate cleaning method of this embodiment will be described.

[0179] In the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, the steel plate 2 is fixed in place vertically or obliquely, and the brush group is moved to simultaneously clean both the front and back sides in a dry manner without using water.

[0180] The automatic steel plate cleaning device 11 may be operated while spraying water.

[0181] In this embodiment, of the brush group, the scraping brush group is oscillated and the wiping brush is moved linearly, but they may be moved only in the vertical direction or only in the horizontal direction (left and right direction), respectively.

[0182] Moreover, the scraping brush group does not necessarily have to be made of metal, and a composite material including the above-mentioned materials may be used.

[0183] The wiping brush may also be made of a composite material including the above-mentioned materials.

[0184] Furthermore, the scraping brush group may be divided into any number of parts other than those already described.

[0185] In the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, when the wire diameter and bristle length of the brushes of each brush group are changed (replaced), various brushes can be replaced depending on the degree of dirt on the steel plate 2 to find the optimum one.

[0186] In other words, experiments are repeated to verify the system and to confirm its operation using actual equipment.

[0187] It should be noted that the stiffness of the brush varies greatly depending on the wire diameter and bristle length.

[0188] 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 the time varies depending on the degree of dirt on the steel plate 2 by changing conditions such as the moving speed, oscillating speed, pressing force, and number of reciprocating movements of the brush group.

[0189] The automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment are of a dry type that does 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 too much clayey soil is attached to the brush group.

[0190] In the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment, it is also possible to operate the device while spraying water directly onto the entire surface of the brush group using a nozzle.

[0191] In addition, the automatic steel plate cleaning device 11 and the automatic steel plate cleaning method of this embodiment are basically designed for indoor use, but by changing the specifications, such as by using stainless steel for some of the components or adding a cover material, they can be designed for outdoor use and can be installed at outdoor construction sites, etc.

[0192] In addition, the automatic steel plate cleaning system, the automatic steel plate cleaning device, and the automatic steel plate cleaning method according to the present invention can also be configured to install a conveyor or the like that can automatically transport the soil and sand scraped off the steel plate to an appropriate position. [Industrial Applicability]

[0193] The automatic steel plate cleaning device of the present invention is applicable to steel plates with attached matter generated at construction sites, etc., and can also be widely and suitably used for steel plates with attached matter used at construction sites for buildings and houses, etc. [Explanation of symbols]
