[0024] Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings. The embodiments described below are merely examples of specific ways to carry out the present invention and are not intended to limit the scope of the invention. Furthermore, in order to facilitate understanding of the explanation, the same reference numerals are used for identical components in each drawing whenever possible, and redundant explanations may be omitted.

[0025] <One Embodiment> [Configuration of the cleaning device] Figure 1 is an external perspective view showing an overview of a cleaning device 100 according to one embodiment of the present invention, and Figure 2 is a side cross-sectional view illustrating how a rubber mat M is cleaned by the cleaning device 100 according to one embodiment of the present invention. The objects to be cleaned by the cleaning device 100 are, for example, steel plates and rubber mats, but here, as an example, a rubber mat M will be used as the object to be cleaned.

[0026] In Figure 1, the cleaning device 100 comprises a mounting section 110, a cleaning section 120, a transport section 130, an auxiliary roller 140, a water tank section 150, a base 160, and control means (not shown).

[0027] The mounting section 110 is configured to accommodate the rubber mat M to be washed, and for example, it is opened on one side so that the rubber mat M can be loaded in from there. Specifically, the rubber mat M is loaded into the mounting section 110 by using a forklift to load it in from one side.

[0028] Furthermore, the mounting section 110 may be equipped with auxiliary rollers 140 for transporting the rubber mat M placed on the mounting section 110 to the washing section 120. The auxiliary rollers 140 do not need to be equipped with a drive source such as a motor, as described later in the transport section (transport roller) 130, and are rollers that assist in the transport of the rubber mat M by rotating in the transport direction of the rubber mat M placed on the auxiliary rollers 140.

[0029] In this embodiment, a base 160 is placed on the mounting section 110, and the rubber mat M is indirectly placed on the mounting section 110 via the base 160. Furthermore, if the base 160 is also placed on an auxiliary roller 140, the auxiliary roller 140 rotates in the transport direction of the base 160, thereby functioning as a roller to assist in the transport of the base 160 and the rubber mat M placed on it.

[0030] The cleaning unit 120 cleans the rubber mat M, which is placed on the mounting unit 110 via the base 160, while moving the rubber mat M. For example, as shown in Figure 2, the cleaning unit 120 cleans the rubber mat M using cleaning water while the rubber mat M, which is placed on the base 160, moves through the area of ​​the cleaning unit 120 by the transport unit (transport roller) 130.

[0031] For example, the cleaning unit 120 includes a plurality of spray units 121 that spray cleaning water from above and below a rubber mat M placed on a base 160 moved by a transport unit (transport roller) 130 within the area of ​​the cleaning unit 120. Furthermore, a pump (not shown) and piping are provided to supply cleaning water to the spray units 121. The cleaning water, pumped up by the pump, is supplied via the piping to the spray units 121 located above and below the base 160 (with the rubber mat M placed on it) as it moves by the transport unit (transport roller) 130. As a result, the rubber mat M placed on the base 160 is cleaned by the spray of cleaning water on its upper and lower surfaces as it moves within the area of ​​the cleaning unit 120.

[0032] The transport unit 130 transports the rubber mat M placed on the mounting unit 110 via the base 160, and typically also moves the rubber mat M (base 160) within the area of ​​the washing unit 120. For example, the transport unit 130 consists of a plurality of transport rollers 130 arranged substantially parallel to each other between the mounting unit 110 and the washing unit 120, and includes a motor to drive the plurality of transport rollers 130.

[0033] A motor drives multiple transport rollers 130 to rotate, transporting the base 160 with the rubber mat M on it from the mounting section 110 to the cleaning section 120. Similarly, multiple transport rollers 130 are also configured in the area of ​​the cleaning section 120, and by rotating these, the base 160 is moved within the area of ​​the cleaning section 120 with the rubber mat M on it, while the rubber mat M is cleaned by the cleaning section 120.

[0034] Multiple transport rollers 130 transport the base 160 with the rubber mat M placed on it to the washing section 120, and further move the base 160 with the rubber mat M placed on it within the area of ​​the washing section 120. Alternatively, the base 160 may be moved back and forth within the area of ​​the washing section 120, and then moved back to the mounting section 110 with the rubber mat M placed on it.

[0035] Furthermore, although the mounting section 110 and the transport section 130 are described separately in this embodiment, the mounting section 110 may also have the function of a transport section 130 capable of transporting the base 160 (including the state in which the rubber mat M is placed) that is placed on the mounting section 110, or the transport section 130 may function as a mounting section 110 on which the base 160 (including the state in which the rubber mat M is placed) can be placed, while also being configured to move the base 160 (including the state in which the rubber mat M is placed). In other words, the mounting section 110 and the transport section 130 may be configured to combine or include each other's functions.

[0036] The water tank section 150 is configured to receive and store from below the cleaning water sprayed toward the rubber mat M by the cleaning section 120, the cleaning water reflected by the rubber mat M, and the foreign matter (dirt) removed from the rubber mat M. Furthermore, the cleaning water stored in the water tank section 150 may be drained as wastewater, or purified (filtered) by removing foreign matter (dirt) and reused as cleaning water. When reused as cleaning water (circulated), the cleaning water stored in the water tank section 150 should be purified, and the purified cleaning water should be supplied to the spray section 121 of the cleaning section 120 using a pump and piping. Foreign matter (dirt) accumulated in the water tank section 150 may be discharged from the cleaning device 100 by a sludge discharge device located at the bottom of the water tank section 150.

[0037] The control means controls the operation of the cleaning unit 120 and the conveying unit 130 described above. For example, the control means controls the start, end (stop), rotation speed and rotation direction of the multiple conveying rollers 130 (motors). The control means also controls which of the spray units 121 in the cleaning unit 120 sprays the cleaning water, the start and end (stop) of the spray unit 121, and the amount and pressure of the sprayed cleaning water.

[0038] Typically, the control means controls the operation of the transport roller 130 (motor) to move the base 160 (including the state on which the rubber mat M is placed) placed on the mounting section 110 to the cleaning section 120, and while the transport roller 130 moves the base 160 (including the state on which the rubber mat M is placed) through the area of ​​the cleaning section 120, the control means controls the operation of the spray section 121 of the cleaning section 120 to clean the rubber mat M placed on the base 160 with cleaning water.

[0039] In this manner, the rubber mat M placed on the base 160 is cleaned by the cleaning device 100.

[0040] [Base configuration] Next, we will explain the configuration of the base 160 in detail. Figure 3 is a schematic diagram showing the state in which the base 160 is placed on the mounting section 110. As shown in Figure 3, the base 160 includes a first member 161, a second member 162, a connecting member 163, and an auxiliary member 164.

[0041] The first member 161 is configured to align with a plurality of transport rollers 132An to 132En (n:1 to 5 in the example shown in Figure 3, and also collectively referred to as "transport rollers 132" hereafter) which are arranged in the direction of movement of the base 160. For example, the transport section 130 has a plurality of rotating shafts 131A to 131E (hereinafter collectively referred to as "rotating shafts 131") which are arranged substantially parallel to each other between the mounting section 110 and the washing section 120, and a plurality of transport rollers 132An to 132En at predetermined intervals on each rotating shaft 131A to 131E. The plurality of transport rollers 132An to 132En are arranged in the direction from the mounting section 110 to the washing section 120 (the direction of movement of the base 160).

[0042] Specifically, the first member 161 of the base 160 is configured to align with the conveyor rollers 132A2 to 132E2 (which are arranged in the direction of movement of the base 160) that are positioned approximately perpendicularly from the mounting section 110 toward the washing section 120, among the conveyor rollers 132An to 132En arranged on the rotation axes 131A to 131E. In Figure 3, the first member 161 of the base 160 is shown resting on the conveyor rollers 132D2 and 132E2 on the mounting section 110 side.

[0043] The second member 162 is substantially parallel to the first member 161 and is configured to align with a plurality of transport rollers 132A4 to 132E4 that are different from the plurality of transport rollers 132A2 to 132E2 that the first member 161 aligns with. Specifically, the second member 162 is formed to face the first member 161, and is configured to align with the transport rollers 132A4 to 132E4, which are among the transport rollers 132An to 132En arranged on the rotation axis 131A to 131E and are arranged substantially perpendicular to the transport rollers 132A4 to 132E4 from the mounting section 110 toward the washing section 120. In Figure 3, the second member 162 of the base 160 is shown resting on the transport rollers 132D4 and 132E4 on the mounting section 110 side.

[0044] The connecting member 163 connects the first member 161 and the second member 162, thereby ensuring the strength of the base 160 while allowing the first member 161 and the second member 162 on the base 160 to move stably along the conveyor rollers 132A2~132E2 and 132A4~132E4.

[0045] Furthermore, the connecting member 163 is preferably configured on the other side (the side with the washing section 120) of the washing device 100, which is opposite to the side with the rubber mat M being brought in, in order to create a space on the side with the washing device 100 that the rubber mat M is brought in (the side with the washing section 120 of the mounting section 110).

[0046] The auxiliary member 164 is formed to extend from the connecting member 163 to the area of ​​the washing device 100 into which the rubber mat M is brought. For example, the auxiliary member 164 is formed approximately in the center between the first member 161 and the second member 162, and approximately parallel to the first member 161 and the second member 162. This makes it difficult for the rubber mat M to be distorted, bent, or folded between the first member 161 and the second member 162 when the rubber mat M is placed on the base 160, allowing it to be placed on the base 160 in a stable state.

[0047] Furthermore, the auxiliary member 164, like the first member 161 and the second member 162, is configured to follow the transport rollers 132A3 to 132C3, which are among the transport rollers 132An to 132En arranged on the rotating shafts 131A to 131E and are positioned substantially perpendicular to the direction from the mounting section 110 towards the washing section 120. This allows the base 160 to move more smoothly.

[0048] Furthermore, as described above, in the base 160, a connecting member 163 is configured on the other side (the side with the washing section 120) to create a space on the side into which the rubber mat M of the washing device 100 is brought. Therefore, the auxiliary member 164 is connected to the connecting member 163 at one end (the base end). In other words, the tip end of the auxiliary member 164 is a free end, and it is necessary to ensure strength at the connection point on the base end.

[0049] Therefore, as shown in Figure 3, the auxiliary member 164 is formed to be shorter than the first member 161 and the second member 162, thereby creating a space on one side of the base 160 while reducing the load on the tip end.

[0050] Figure 4 is a schematic diagram showing the state in which the rubber mat M is placed on the base 160. As shown in Figure 4, the rubber mat M is placed on the base 160 which is placed on the mounting section 110.

[0051] Although the rubber mat M is more prone to deformation, distortion, bending, and creasing than iron or steel plates, it is supported by the first member 161, the second member 162, the connecting member 163, and the auxiliary member 164 when placed on the base 160. It can be said that the rubber mat M is stably placed on the mounting section 110 via the base 160.

[0052] In this state, by driving the transport unit 130 (rotating shafts 131A to 131E and transport rollers 132An to 132En), the base 160 moves toward the washing unit 120 and within the area of ​​the washing unit 120 with the rubber mat M placed on it. At that time, the rubber mat M placed on the moving base 160 is washed by spraying washing water toward its upper and lower surfaces. However, because it is supported and stably placed on the base 160, it is less likely to deform, warp, bend, or fold, and the risk of it falling or getting caught between the transport unit 130 (rotating shafts 131A to 131E) is reduced. As a result, the rubber mat M can be properly washed.

[0053] Figure 5 is a schematic diagram showing how a rubber mat M is placed on a base 160 positioned on the mounting section 110 by a forklift F. As shown in Figure 5, the base 160 positioned on the mounting section 110 is configured such that a space is formed between the first member 161 and the second member 162 on the side of the mounting section 110 in the washing device 100 into which the object to be washed is brought. Furthermore, the auxiliary member 164 is also formed to be shorter than the first member 161 and the second member 162, approximately in the center between the first member 161 and the second member 162.

[0054] This prevents the forks of the forklift F from interfering with the base 160 (first member 161, second member 162, and auxiliary member 164) when attempting to place the rubber mat M onto the base 160, allowing the rubber mat M to be placed smoothly onto the base 160.

[0055] As described above, according to the cleaning device 100 of one embodiment of the present invention, the base 160 placed on the mounting section 110 comprises a first member 161 configured to align with a plurality of transport rollers 132A2 to 132E2, and a second member 162 configured to align with a plurality of transport rollers 132A4 to 132E4. Therefore, regardless of the material or size of the object to be cleaned, for example, even a rubber mat M can be placed on the base 160, and the base 160 (with the rubber mat M placed on it) can be moved through the area of ​​the cleaning section 120 by the transport section 130, allowing for smooth movement and proper cleaning.

[0056] In this embodiment, only one auxiliary member 164 was formed approximately in the center between the first member 161 and the second member 162. However, this is not limited to this configuration. For example, depending on the arrangement of the conveyor rollers 132 and the number and shape of the forks of the forklift F, auxiliary members 164 may be formed in locations other than the center, or multiple auxiliary members may be formed.

[0057] [First application example of the base configuration] Figure 6A is a plan view showing a base 260 as a first application example used in a cleaning device 100 according to one embodiment of the present invention, and Figure 6B is a front view showing cleaning water being sprayed with a rubber mat M placed on the base 260. As shown in Figure 6A, the base 260 includes a first member 261, a second member 262, a connecting member 263, and an auxiliary member 264.

[0058] The first member 261, the second member 262, the connecting member 263, and the auxiliary member 264 correspond to the first member 161, the second member 162, the connecting member 163, and the auxiliary member 164 of the base 160 described in Figures 3 to 5, respectively, but differ in that the first member 261, the second member 262, and the auxiliary member 264 have multiple protrusions T formed on them.

[0059] The projection T is formed on the surface of the base 260 on which the object to be cleaned is placed, and as shown in Figure 6B, it reduces the contact area with the object to be cleaned (in this case, the rubber mat M) placed on the base 260. This reduces the area on the underside of the object to be cleaned that is blocked by the base 260 from the cleaning water sprayed from the spray unit 121, and the underside of the object to be cleaned can be properly cleaned.

[0060] The projections T were provided in multiples on the first member 261, the second member 262, and the auxiliary member 264, but are not limited to this. Any configuration that reduces the contact area with the object to be cleaned placed on the base 260 may be used. For example, the mounting surface of the base 260 on which the object to be cleaned is placed may be tapered, and projections may be formed in the shapes of the first member 261, the second member 262, and the auxiliary member 264 themselves.

[0061] Furthermore, at least a portion of the base 260 may be made of mesh, perforated metal, or the like. When cleaning an object placed on the base 260 by spraying cleaning water onto it, the portion of the cleaning water sprayed from the underside of the object that is being cleaned that is obstructed by the base 260 is reduced, allowing the object to be cleaned more effectively.

[0062] [Second application example of the base configuration] Figure 7A is a perspective view from the bottom side showing a base 360 ​​as a second application example used in a cleaning device 100 according to one embodiment of the present invention, and Figure 7B is a front view showing cleaning water being sprayed with a rubber mat M placed on the base 360. As shown in Figure 7A, the base 360 ​​includes a first member 361, a second member 362, a connecting member 363, and an auxiliary member 364.

[0063] The first member 361, the second member 362, the connecting member 363, and the auxiliary member 364 correspond to the first member 161, the second member 162, the connecting member 163, and the auxiliary member 164 of the base 160 described in Figures 3 to 5, respectively. The first member 361 and the second member 362 have guide grooves formed in the direction of movement of the base 360. As shown in Figure 7B, these guide grooves are configured to clamp the conveyor roller 130 from both sides so as to cover it from above, and to fit into the conveyor roller 132. As a result, when the base 360 ​​moves between the placement section 110 and the washing section 120, and within the area of ​​the washing section 120, with the rubber mat M, which is the object to be washed, placed on it, it can move smoothly along the conveyor roller 130 in the appropriate direction of movement while preventing it from falling off the conveyor roller 130.

[0064] In this example, guide grooves are formed on both the first member 361 and the second member 362. However, if smooth movement is possible while preventing the members from falling off the transport roller 130, then a configuration in which guide grooves are formed on only one of them is also acceptable.

[0065] The connecting member 363 has an adjustment means that allows the length of the connecting member 363 to be adjusted. Specifically, the connecting member 363 is provided with a sliding mechanism so that it can be extended and retracted, and the distance between the first member 361 and the second member 362 can be adjusted. As a result, the distance between the first member 361 and the second member 362 can be adjusted according to the spacing (width direction) at which the conveyor rollers 132 are arranged, so that the first member 361 and the second member 362 can be appropriately positioned along the conveyor rollers 132.

[0066] Furthermore, the size of the base 360 ​​can be adjusted according to the size of the object to be cleaned placed on the base 360.

[0067] In addition, while Figures 6A, 6B, 7A, and 7B illustrate application examples of the configuration of the base used in the cleaning device 100 according to one embodiment of the present invention, the bases 260 and 360 do not necessarily have to be implemented in the manner shown in the figures. For example, some or all of the configuration of base 260 or 360 may be applied to base 160, or some or all of the configurations of both may be applied to each.

[0068] Furthermore, although the object to be cleaned by the cleaning device 100 was described as a rubber mat M in one embodiment of the present invention, the object to be cleaned is not limited to this, and may be, for example, a resin (plastic) plate, a steel plate or sheet metal, or any other plate-shaped object of various sizes and shapes.

[0069] Lightweight or soft objects to be cleaned are supported and stably placed on the base 160, allowing them to be smoothly transported through the area of ​​the cleaning unit 120 even when cleaning water is sprayed in the cleaning unit 120. As a result, objects made of materials other than steel, such as rubber or resin (plastic), can be properly cleaned.

[0070] Furthermore, small or narrow objects to be cleaned, such as those that would get stuck between the rotating shafts 131A to 131E or fall through the system, or those that would not fit on the multiple transport rollers 132An to 132En, can be smoothly transported by being placed on the base 160. As a result, even small or narrow objects to be cleaned can be properly cleaned.
