Description

[Technical Field]

[0001] The present invention relates to a floor board cleaning device and a floor board cleaning method. [Background technology]

[0002] Generally, there are floor plates used at construction sites, work sites, etc. Floor plates are, for example, steel floor plates, and are laid (temporarily) for purposes such as securing a route for carrying in materials, protecting the work floor and ground, and securing footing on soft ground.

[0003] Cleaning devices for cleaning such floor plates are known. For example, Patent Document 1 discloses a cleaning device for iron floor plates that safely and economically removes dirt from iron floor plates for temporary walkways, which are often used at construction sites, in preparation for reuse. Specifically, the cleaning device for iron floor plates disclosed in Patent Document 1 removes dirt from the surface of the iron plate by spraying cleaning liquid water using a washer while the iron floor plate is transported by a transport roller device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-80783 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the iron sheet cleaning device described in Patent Document 1, the iron sheet to be cleaned must be installed straight in the conveying direction. If it is installed at an angle, the iron sheet may protrude from the conveying path or get caught on the frame, and the cleaning water may not properly reach the edge of the iron sheet. As a result, the iron sheet cannot be properly cleaned.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and one of the objects of the present invention is to provide a floor board cleaning device and a floor board cleaning method that can properly clean floor boards even if the floor boards are installed at an angle to the transport path or if they become tilted during transport. [Means for solving the problem]

[0010] In the above aspect, the first time period may be a time period required for at least two or more points of the floor plate to come into contact with the guide portion after the floor plate passes through the predetermined passing position.

[0011] In the above aspect, the device may further include a contact detection means for detecting contact between the floor plate and the guide portion, and the control means may control the operation of the moving means so that the floor plate continues to move in the same direction for a second time after contact between the floor plate and the guide portion is detected by the contact detection means, and then moves back in the opposite direction.

[0012] In the above aspect, the device may further include a contact detection means for detecting contact between the floor plate and the guide portion, and the control means may control the operation of the moving means so that the floor plate continues to move in the same direction until the contact detection means detects at least two contacts between the floor plate and the guide portion, and then moves back in the opposite direction.

[0013] In the above aspect, the contact between the base plate and the guide portion may include indirect contact via a detection component.

[0014] In the above aspect, the apparatus may further include a placement guide portion disposed above the placement table on one side of the cleaning area in a direction substantially perpendicular to the first direction and the second direction.

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that each embodiment described below is merely a specific example for carrying out the present invention and is not intended to limit the scope of the present invention. Furthermore, to facilitate understanding of the description, the same components in each drawing will be designated by the same reference numerals wherever possible, and duplicate descriptions may be omitted.

[0020] First Embodiment [Configuration of floor cleaning equipment] FIG. 1 is a diagram showing how a floor board P to be cleaned is placed on a floor board cleaning apparatus 100 according to a first embodiment of the present invention using a forklift F, and FIG. 2 is a plan view showing an overview of the floor board cleaning apparatus 100 according to the first embodiment of the present invention.

[0021] Figure 1 shows a side cross-sectional view of the floor board cleaning device 100, which comprises a mounting platform 110, a moving means 120, a cleaning means 130, a guide section 140, a side wall section 150, a water tank section 160, and a control means (not shown).

[0022] The platform 110 is configured so that the floor plate P can be placed between one side having a carry-in section A1 into which the floor plate P can be carried in and the other side opposite the one side. Note that the carry-in section A1 is an opening that allows the floor plate P held by a forklift F to be carried in, for example, and it is sufficient that no members or the like that may obstruct the carry-in are placed above the platform 110 onto which the floor plate P is to be placed.

[0023] The moving means 120 has a transport mechanism disposed between one side and the other side, and the transport mechanism operates to move the floor plate P placed on the mounting table 110. For example, the transport mechanism is composed of a plurality of rollers, and the plurality of rollers are rotated by a motor or the like to transport the floor plate P placed on the mounting table 110 in a first direction or a second direction. More specifically, as shown in FIG. 2, the moving means 120 has a plurality of rotating shafts 121 arranged substantially parallel to each other so as to extend in a direction substantially perpendicular to the first direction and the second direction, and each rotating shaft 121 has a plurality of bearings arranged to support the rotating shaft 121. A plurality of rollers 122 are attached to each of the rotating shafts 121 at predetermined intervals, and as the plurality of rotating shafts 121 are rotated by the motor, the plurality of rollers 122 also rotate to transport the placed floor plate P.

[0024] Here, the first direction is a direction from one side to the other side, and the second direction is a direction opposite to the first direction, from the other side to the one side.

[0025] In this embodiment, the conveying mechanism in the moving means 120 is composed of multiple rotating shafts 121 and rollers 122, but is not limited to this and may be other configurations, such as a conveyor belt, as long as it is capable of conveying the floor plate P placed on the mounting table 110 in the first and second directions.

[0026] Furthermore, in this embodiment, the mounting table 110 and the moving means 120 are described separately, but the mounting table 110 may have the function of a moving means capable of moving the floor plate P placed on the mounting table 110, or the moving means 120 may function as a mounting table on which the floor plate P can be placed, while also moving the floor plate P. In other words, the mounting table 110 and the moving means 120 may be configured to have or include each other's functions.

[0027] The cleaning means 130 cleans the floor plate P with cleaning water while the floor plate P is being moved through the cleaning area A2 by the moving means 120. Here, the cleaning area A2 is an area located on the other side of the loading section A1, and is an area into which the cleaning means 130 releases cleaning water.

[0028] For example, the cleaning means 130 includes spray units that spray cleaning water from above and below the mounting table 110 in the cleaning area A2, and further includes a pump and piping that supply cleaning water to the spray units. Cleaning water pumped up by driving the pump is supplied to the spray units arranged above and below the mounting table 110 via the piping. As shown in FIG. 2, the cleaning means 130 includes piping 131 that extends in a direction approximately perpendicular to the first direction and the second direction, and multiple nozzles 132 are arranged on the piping 131. Then, cleaning water is sprayed from each nozzle 132 toward the upper surface and / or lower surface of the floor plate P moving in the cleaning area A2, thereby cleaning the floor plate P.

[0029] The cleaning means 130 may clean the upper and lower surfaces of the floor plate P by spraying cleaning water onto the upper and lower surfaces of the floor plate P from spray units (nozzles) arranged above and below the mounting table 110. Since the upper and lower surfaces of the floor plate P can be cleaned simultaneously, the cleaning time can be shortened.

[0030] Furthermore, when the floor plate P placed on the mounting table 110 moves back and forth between one side and the other, during the first round trip, cleaning water may be sprayed from a spray unit located above the mounting table 110 toward the upper surface of the floor plate P to clean the upper surface of the floor plate P, and during the second round trip, cleaning water may be sprayed from a spray unit located below the mounting table 110 toward the underside of the floor plate P to clean the underside of the floor plate P. Since the pressure at which the cleaning water is sprayed can be increased in each case, more powerful cleaning can be achieved. Similarly, the upper surface of the floor plate P may be cleaned on the outbound trip, and the underside of the floor plate P may be cleaned on the return trip.

[0031] The guide section 140 is disposed at the other end of the mounting table 110. The guide section 140 is disposed at the other end so as to come into contact with the base plate P moved in the first direction by the moving means 120, and for example, at least two guide sections 140 are disposed in a direction approximately perpendicular to the first direction, or one guide section 140 is formed so as to extend in a direction approximately perpendicular to the first direction. Here, as shown in FIG. 2, four guide sections 140 are disposed at the other end of the mounting table 110.

[0032] In other words, the guide part 140 is configured at the other end of the mounting table 110 in a direction approximately perpendicular to the first direction, and is configured to come into contact with at least two or more points of the floor plate P moved by the moving means 120. As a result, even if the floor plate P is tilted with respect to the first direction, the tilt is corrected.

[0033] The side wall 150 is formed at the other end of the mounting table 110, and prevents, for example, the cleaning water sprayed by the cleaning means 130 toward the floor plate P and the cleaning water reflected by the floor plate P from scattering. If the upper part of the side wall 150 is shaped so as to bend toward the cleaning means 130, scattering of the cleaning water can be more appropriately prevented. Furthermore, the side wall 150 may be formed to cover the area where the cleaning means 130 is arranged, the cleaning area A2, or the entire area on the other side thereof. This further appropriately prevents scattering of the cleaning water.

[0034] The water tank section 160 is configured to receive and store from below the cleaning water sprayed toward the floor plate P by the cleaning means 130, the cleaning water reflected by the floor plate P, and foreign matter (dirt) removed from the floor plate P. Furthermore, the cleaning water stored in the water tank section 160 may be discharged as wastewater or purified (filtered) by removing foreign matter (dirt) and reused as cleaning water. When reused (circulated) as cleaning water, the cleaning water stored in the water tank section 160 can be purified and the purified cleaning water can be supplied to the spray section of the cleaning means 130 using a pump and piping. Foreign matter (dirt) accumulated in the water tank section 160 can be discharged from the floor plate cleaning device 100 by a sludge removal device located at the bottom of the water tank section 160.

[0035] The control means controls the operations of the above-mentioned moving means 120 and cleaning means 130. For example, the control means controls the start and end (stop) of operation, the rotation speed and rotation direction, etc. of the conveying mechanism (roller) in the moving means 120. The control means also controls which of the spraying units in the cleaning means 130 will spray cleaning water, the start and end (stop) of operation of the spraying unit, and the amount and pressure of the sprayed cleaning water.

[0036] Typically, the control means controls the operation of the moving means 120 to move the floor plate P placed on the mounting table 110 in a first direction or a second direction, and controls the operation of the cleaning means 130 to clean the floor plate P with cleaning water while the floor plate P is moving through the cleaning area A2 by the moving means 120. Then, when the floor plate P placed on the mounting table 110 moves in the first direction so that at least a part of the floor plate P reaches the guide section 140, the control means controls the operation of the moving means 120 to move the floor plate P back in the second direction (opposite direction) after a predetermined time has elapsed since the floor plate P reached the guide section 140.

[0037] Specific examples of the moving means 120 and the cleaning means 130 whose operation is controlled by the control means will be described later.

[0038] [Plate transport control] Next, a detailed description will be given of how the floor plate P placed on the table 110 is moved in the first direction until it reaches the guide portion 140 and then returns to the second direction.

[0039] 3 is a diagram illustrating a state in which the floor plate P moves in a first direction and then returns to the second direction in the floor plate cleaning device 100 according to the first embodiment of the present invention. As shown in FIG. 3, the floor plate P moves in the first direction in an inclined state, and when it comes into contact with the guide part 140, the inclination is corrected and the floor plate P moves in the second direction.

[0040] Specifically, for example, it is assumed that the base plate P is placed on the table 110 in a state inclined with respect to the first direction (state (a)).

[0041] The floor plate P is moved in the first direction by the moving means 120 and passes through a predetermined passing position D1 between one side and the other side (state (b)). The floor plate cleaning device 100 is equipped with, for example, a proximity sensor (passing detection means) that detects that the floor plate P has passed through the predetermined passing position D1. Note that the proximity sensor can detect the approach of an object to be detected in a non-contact manner using electromagnetic induction or the like, but is not limited to this. For example, an infrared sensor or other optical sensor may be used to detect that the floor plate P has passed through the predetermined passing position D1.

[0042] Then, the control means receives from the passage detection means that the floor plate P has passed through the predetermined passage position D1, and then controls the operation of the moving means 120 so that the floor plate P continues to move in the first direction for a first time period (e.g., approximately 5 to 10 seconds) (state (b) to state (d)).

[0043] Here, the first time period is the time required for at least two points of the floor plate P to come into contact with the guide portion 140 after the floor plate P passes through the predetermined passing position D1. In other words, it is the time required for the floor plate P to move from the state (b) to the state (d).

[0044] Thereafter, the control means controls the operation of the moving means 120 so as to move the floor plate P back in the second direction (states (e) to (h)). In state (d), the inclination of the floor plate P has been corrected, so that the floor plate P can move in a substantially straight state in the second direction.

[0045] Furthermore, even if the floor plate P is repeatedly moved in the first direction and the second direction, the floor plate P can be moved in a substantially straight state in the first direction and the second direction.

[0046] Figure 4 is a diagram showing the operation control of the moving means 120 and the cleaning means 130 corresponding to the situation shown in Figure 3. As shown in Figure 4, the control means controls the moving means 120 to move the floor plate P in a first direction (period T1), and then controls the moving means 120 to move the floor plate P back in the second direction at time t2 (period T2). As explained in Figure 3, after the floor plate P passes through the predetermined passing position D1 (time t1), the moving means 120 is controlled so that the floor plate P continues to move in the first direction for a first time (t).

[0047] Furthermore, the control means controls the cleaning means 130 to spray cleaning water toward the floor plate P while the floor plate P is moving through the cleaning area A2, thereby cleaning the floor plate P. For example, the control means may operate the cleaning means 130 by detecting the start timing S when the floor plate P enters the cleaning area A2, and may stop the cleaning means 130 by detecting the end timing E when the floor plate P leaves the cleaning area A2. The start timing S and end timing E may be detected by various sensors, or may be calculated from the start time of the transport of the floor plate P or the start time of the return movement.

[0048] [How to clean floor boards] Next, a method for cleaning the floor plate P while moving it using the floor plate cleaning device 100 will be specifically described in detail.

[0049] 5 is a flowchart showing the processing flow of a floor board cleaning method M100 executed by the floor board cleaning apparatus 100 according to the first embodiment of the present invention. As shown in FIG. 5, the floor board cleaning method M100 includes steps S110 to S150, and each step is executed by a processor included in the floor board cleaning apparatus 100.

[0050] In step S110, the control means starts driving the moving means 120 so as to move the floor plate P placed on the mounting table 110 in the first direction, and then controls the moving means 120 to continue this movement (first movement step). As a specific example, the motor is driven to rotate the rotation shaft 121 (roller 122) in the first direction.

[0051] In step S120, the control means cleans the floor plate P with cleaning water while the floor plate P is moving through the cleaning area A2 in step S110 (first cleaning step). As a specific example, cleaning water is sprayed from a spraying unit (nozzle) toward the upper and / or lower surfaces of the floor plate P.

[0052] In step S130, the control means determines whether or not the floor plate P has reached the guide portion 140 (reach determination step). As a specific example, the control means detects that the floor plate P has passed a predetermined passing position D1 (time t1), and then determines that the floor plate P has reached the guide portion 140 after a first time t has elapsed. Here, the fact that the floor plate P has reached the guide portion 140 means that a predetermined time has elapsed since a part of the floor plate P abutted against the guide portion 140, and that at least two points of the floor plate P abut against the guide portion 140, causing the floor plate P to become approximately straight in the first direction (second direction).

[0053] In step S140, after it is determined that the floor plate P has reached the guide portion 140 ("Yes" in step S130), the control means starts driving the moving means 120 to move the floor plate P in the second direction, and then controls it to continue this (second moving step). As a specific example, the motor is driven to rotate the rotating shaft 121 (roller 122) in the second direction.

[0054] In step S150, the control means cleans the floor plate P with cleaning water while the floor plate P is moving through the cleaning area A2 in step S140 (second cleaning step). As a specific example, cleaning water is sprayed from a spraying unit (nozzle) toward the upper and / or lower surfaces of the floor plate P.

[0055] As described above, according to the floor board cleaning device 100 and floor board cleaning method M100 of the first embodiment of the present invention, the floor board P placed on the mounting table 110 is moved in the first direction and brought into contact with the guide portion 140, thereby making the floor board P approximately straight in the first direction and the second direction. As a result, even if the floor board P is placed at an angle with respect to the transport path (first direction and second direction) or if it becomes tilted during transport, the floor board P can be properly cleaned.

[0056] In this embodiment, a non-contact sensor such as a proximity sensor is used to detect that the floor plate P has passed through a predetermined passing position D1, and after a predetermined time has passed since that detection, it is determined that the floor plate P has become approximately straight in the first direction in the guide section 140.However, this is not limited to this, and for example, a contact sensor that detects contact with the guide section 140 may also be used.

[0057] 6 is a diagram schematically illustrating another manner in which the floor plate P moves in a first direction and then returns to the second direction in the floor plate cleaning device 100 according to the first embodiment of the present invention. As shown in FIG. 6, the floor plate P moves in the first direction in an inclined state, and when it comes into contact with the guide part 140, the inclination is corrected and the floor plate P moves in the second direction.

[0058] The floor board cleaning device 100 includes a contact sensor (contact detection means) such as a switch, and detects that the floor board P has contacted the guide portion 140 (contact position D2). The control means receives from the contact detection means that the floor board P has contacted the contact position D2, and then controls the operation of the moving means 120 so that the floor board P continues to move in the first direction for a second time period (for example, about 5 to 10 seconds) (state (c) and state (d)).

[0059] Here, the second time is the time required for at least two points of the floor plate P to abut against the guide portion 140 after the floor plate P contacts the predetermined contact position D2. In other words, it is the time required for the floor plate P to move from the state (c) to the state (d).

[0060] Thereafter, the control means controls the operation of the moving means 120 so as to move the floor plate P back in the second direction (states (e) to (h)). In state (d), the inclination of the floor plate P has been corrected, so that the floor plate P can move in a substantially straight state in the second direction.

[0061] The contact detection means may be configured to detect indirect contact between the floor plate P and the guide portion 140 via a detection component. For example, if the floor plate P is entirely or partially made of a non-metallic material such as plastic or rubber, the contact sensor may not be able to detect the contact even if that part directly contacts the guide portion 140. In that case, a metal detection component that contacts the floor plate P may be provided, and the detection component may contact the guide portion 140 in conjunction with contact between the floor plate P and the detection component.

[0062] Fig. 7 is a diagram showing the operation control of the moving means 120 and the cleaning means 130 corresponding to the state shown in Fig. 6. As shown in Fig. 7, the control means controls the moving means 120 to move the floor plate P in a first direction (period T1), and then controls the moving means 120 to move the floor plate P in a second direction at time t2 (period T2). As explained in Fig. 6, after the floor plate P contacts the contact position D2 (time t1'), the moving means 120 is controlled so that the floor plate P continues to move in the first direction for a second time t'.

[0063] As also explained in Figure 4, the control means controls the cleaning means 130 to spray cleaning water toward the floor plate P while the floor plate P is moving through the cleaning area A2, thereby cleaning the floor plate P.

[0064] Here, the control means controls the moving means 120 to move the floor plate P in the second direction at turning back time t2, which is the second time t' after the floor plate P comes into contact with contact position D2 (time t1'), but the control means may also control the moving means 120 to move the floor plate P in the second direction in response to the contact detection means detecting a second contact between the floor plate P and the guide section 140 (contact position D2). Specifically, the control means continues to move the floor plate P in the first direction from the time the contact detection means detects the first contact between the floor plate P and the guide section 140 (contact position D2) until the second contact is detected, and then, after the second contact is detected, the control means causes the floor plate P to move in the second direction.

[0065] Second Embodiment Next, in a second embodiment of the present invention, a guide portion is arranged in a different position instead of the guide portion 140 described in the first embodiment. In this embodiment, the description of matters common to the first embodiment of the present invention will be omitted or simplified, and differences will mainly be described.

[0066] FIG. 8 is a side cross-sectional view showing an overview of a floor board cleaning apparatus 200 according to a second embodiment of the present invention, and FIG. 9 is a plan view showing an overview of a floor board cleaning apparatus 200 according to the second embodiment of the present invention.

[0067] 8 and 9, in the floor plate cleaning device 200, the guide portion 240 is formed at one end of the mounting table 110. The guide portion 240 is arranged at one end so as to come into contact with the floor plate P moved in the second direction by the moving means 120, and for example, at least two guide portions 240 are arranged in a direction approximately perpendicular to the second direction, or one guide portion 240 is formed so as to extend in a direction approximately perpendicular to the second direction. Here, as shown in FIG. 9, two L-shaped guide portions 240 are arranged at one end of the mounting table 110.

[0068] In other words, the guide section 240 is configured at one end of the mounting table 110 in a direction approximately perpendicular to the second direction, and is configured to come into contact with at least two or more points of the floor plate P moved by the moving means 120. As a result, even if the floor plate P is tilted with respect to the second direction, the tilt is corrected.

[0069] 10 is a diagram schematically illustrating how a floor plate P moves in the second direction and then returns to the first direction in a floor plate cleaning device 200 according to a second embodiment of the present invention. As shown in FIG. 10, first, the floor plate P moves in the second direction in an inclined state, and then comes into contact with the guide portion 240, thereby correcting the inclination (state (a) to state (b)).

[0070] The control means may use the procedure described in the first embodiment of the present invention to realize that the floor plate P reaches the guide portion 240 and becomes substantially straight in the second direction. Specifically, the floor plate cleaning device 200 may be configured to include a passage detection means that detects that the floor plate P passes through a predetermined passage position between the position where the floor plate P is placed on the mounting table 110 and the guide portion 240, or a contact detection means that detects contact between the floor plate P and the guide portion 240.

[0071] Furthermore, the procedure of first moving the floor plate P in the second direction and bringing it into contact with the guide part 240 to make the floor plate P approximately straight in the second direction may be confirmed by an operator, since this is a preliminary position setting (tilt adjustment) performed when cleaning the floor plate P. In other words, the floor plate cleaning device 200 may be configured to have the operator confirm that the floor plate P has reached the guide part 240 and become approximately straight in the second direction by moving the floor plate P in the second direction, and to accept the confirmation result.

[0072] In this way, once the floor plate P is approximately straight in the second direction, the control means then controls the operation of the moving means 120 to move the floor plate P in the first direction (states (c) to (f)), and when it reaches the other end, to move the floor plate P back in the second direction (states (g) to (j)). Note that while the floor plate P is being moved by the moving means 120 through the cleaning area A2, the control means controls the cleaning means 130 to clean the floor plate P with cleaning water.

[0073] 11 is a flowchart showing the process flow of a floor board cleaning method M200 executed by a floor board cleaning apparatus 200 according to the second embodiment of the present invention. As shown in FIG. 11, the floor board cleaning method M200 includes steps S210 to S260, and each step is executed by a processor included in the floor board cleaning apparatus 200.

[0074] In step S210, the control means controls the operation of the moving means 120 so as to move the sole plate P placed on the table 110 in the second direction (pre-movement step).

[0075] In step S220, the control means determines whether or not the floor plate P has reached the guide portion 240 (reach determination step). Here, the fact that the floor plate P has reached the guide portion 240 means that at least two points of the floor plate P come into contact with the guide portion 240, causing the floor plate P to become substantially straight in the second direction (first direction).

[0076] In step S230, after determining that the floor plate P has reached the guide section 240 ("Yes" in step S220), the control means starts driving the moving means 120 to move the floor plate P in the first direction, and then controls it to continue doing so (first moving step).

[0077] In step S240, the control means cleans the floor plate P with cleaning water while the floor plate P is moving through the cleaning area A2 in step S230 (first cleaning step).

[0078] In step S250, the control means starts driving the moving means 120 to move the floor plate P in the second direction after the floor plate P reaches the other end, and then controls it to continue doing so (second moving step).

[0079] In step S260, the control means cleans the floor plate P with cleaning water while the floor plate P is moving through the cleaning area A2 in step S250 (second cleaning step).

[0080] As described above, according to the floor board cleaning device 200 and floor board cleaning method M200 according to the second embodiment of the present invention, the floor board P placed on the mounting table 110 is first moved in the second direction, and the floor board P is brought into contact with the guide portion 240, thereby making the floor board P approximately straight in advance in the first and second directions. As a result, even if the floor board P is placed at an angle with respect to the transport path (first and second directions) or if it becomes tilted during transport, when cleaning the floor board P, it can be moved in an approximately straight state in the first and second directions, and can be properly cleaned.

[0081] <Other> Fig. 12 is a diagram showing how a floor board P to be cleaned is placed on a floor board cleaning apparatus 300 according to another embodiment of the present invention using a forklift F. As shown in Fig. 12, the floor board cleaning apparatus 300 has a placement guide unit 340 added to it compared to the floor board cleaning apparatus 100 according to the first embodiment of the present invention.

[0082] The placement guide portion 340 is disposed above the placement table 110 on one side of the cleaning area A2. At least two placement guide portions 340 are disposed in a direction substantially perpendicular to the first and second directions, and for example, four placement guide portions 340 may be disposed in a direction substantially perpendicular to the first and second directions, like the guide portion 140 shown in Fig. 2. Alternatively, one placement guide portion 340 may be formed so as to extend in a direction substantially perpendicular to the first and second directions.

[0083] When using a forklift F to place the floor board P to be cleaned, the floor board P can be placed in a substantially straight state in the first and second directions by abutting the floor board P against the placement guide portion 340 and placing it directly on the placement table 110.

[0084] Fig. 13 is a plan view showing an overview of a floor board cleaning apparatus 400 according to another embodiment of the present invention. As shown in Fig. 13, compared to the floor board cleaning apparatus 100 according to the first embodiment of the present invention, the floor board cleaning apparatus 400 additionally includes an auxiliary guide unit 440. The auxiliary guide unit 440 is configured to be detachable, for example, by providing a guide mounting member on the mounting table 110.

[0085] Specifically, when the size of the floor board P to be cleaned in the width direction (approximately perpendicular to the first direction and the second direction) is small, it is advisable to arrange the auxiliary guide portion 440 using a guide mounting member. The floor board P placed on the mounting table 110 is transported from one side to the other by the moving means 120, and even when the floor board P is transported at an angle with respect to the first direction, the auxiliary guide portion 440 functions as a side wall and can appropriately guide the floor board P to the other side. Note that when the auxiliary guide portion 440 is made to function as a side wall, the interval at which the auxiliary guide portions 440 are arranged should be larger than the size of the floor board P in the width direction.

[0086] Furthermore, when the size of the floor board P to be cleaned in the length direction is small (when the sizes in the first and second directions when placed on the placing table 110 are small), it is advisable to arrange the auxiliary guide parts 440 using a guide attachment member. As a result, the floor board P placed on the placing table 110 is transported from one side to the other by the moving means 120, but the auxiliary guide parts 440 function as a turning position, and the floor board P can be turned back halfway and moved without being transported to the end on the other side. Note that when the auxiliary guide parts 440 are made to function as turning positions, the interval at which the auxiliary guide parts 440 are arranged should be smaller than the size of the floor board P in the width direction.

[0087] The above-described embodiments are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The elements of each embodiment, as well as their arrangement, materials, conditions, shapes, sizes, etc., are not limited to those illustrated and can be modified as appropriate. Furthermore, configurations shown in different embodiments can be partially substituted or combined with each other. [Explanation of symbols]
