Description

  The present invention relates to an article cleaning apparatus for cleaning articles such as pallets, article transport containers such as containers, machine parts and instruments used to hold and transport various articles.

  Article transport containers called pallets, containers, and the like need to be washed at a predetermined frequency in order to clean physical distribution, demand for hygiene and environmental considerations, and the like. However, since pallets, containers, and the like have a size of about several tens of cm to 1 m in length and width, a dedicated cleaning device is required to wash them in large quantities. Patent Document 1 and Patent Document 2 disclose dedicated apparatuses for cleaning the article transport containers called pallets and containers.

  That is, a cleaning chamber provided with an open / close door, a support frame rotatably provided in the cleaning chamber, and a cleaning liquid (cleaning liquid, rinsing liquid) from the outside of the support frame toward the support frame Nozzle mechanism. The support frame is formed in a substantially rectangular basket shape in which a plurality of rod-like members are arranged vertically and horizontally. The article transport container is accommodated in the support frame and cleaned. That is, since the support frame is formed by arranging the rod-shaped members vertically and horizontally, when the cleaning liquid is ejected from the nozzle mechanism, the cleaning liquid is supplied into the support frame from the gap between the rod-shaped members. Thus, the article transport container accommodated in the support frame is cleaned.

Japanese Utility Model Publication No. 56-44888 Japanese Patent No. 5437749

In Patent Document 1 and Patent Document 2, a cleaning liquid is ejected from a plurality of nozzles fixed above a support frame to a container to be cleaned contained in the rotating support frame. Further, a cleaning liquid is ejected from a plurality of nozzles fixed below the support frame to the container to be cleaned in the support frame.
However, since the cleaning liquid is ejected from a plurality of nozzles, it is not clear which part of the container to be cleaned is ejected. Further, since the container to be cleaned may be unevenly distributed and housed in a part of the support frame, the cleaning liquid may be sprayed to a place where the container to be cleaned is not present. That is, the cleaning liquid has been jetted wastefully. In addition, since there are a plurality of nozzles, it is necessary to eject a large amount of cleaning liquid. Therefore, the capacity of the pump for supplying the cleaning liquid is increased.

  This invention is made | formed in view of the above, and makes it a subject to provide the washing | cleaning apparatus for articles | goods which enables it to wash | clean efficiently even if there are few nozzles for injection. In addition, an object of the present invention is to provide an article cleaning apparatus capable of changing the spray range of the cleaning liquid in accordance with the arrangement state of the articles.

  In order to solve the above-described problems, an article cleaning apparatus according to the present invention is provided in a cleaning chamber so as to be rotatable substantially horizontally, and supports a support frame body that can support the article, and an article supported by the support frame body. A cleaning mechanism for supplying the liquid, wherein the cleaning mechanism is disposed above the support frame and is used for cleaning from above to below the support frame. The upper nozzle is provided with an upper nozzle that ejects the liquid, and the upper nozzle is provided on an upper arm that rotates substantially horizontally, and a liquid supply pipe system that supplies the cleaning liquid to the upper nozzle is provided. A lower arm disposed below the support frame and ejecting a cleaning liquid from below to above the support frame, wherein the lower nozzle rotates substantially horizontally And the lower node Characterized in that it comprises at least one of the lower cleaning mechanism liquid supply pipe system for supplying the liquid for the cleaning Le is provided.

The upper arm or the lower arm is provided so that the upper nozzle or the lower nozzle rotates along an arc extending from an arbitrary position on the outer periphery of the support frame to the vicinity of the rotation center. preferable.
It is preferable that both the upper cleaning mechanism and the lower cleaning mechanism are provided.

  It is preferable that the upper arm of the upper cleaning mechanism and the lower arm of the lower cleaning mechanism are provided so as to be integrally rotatable.

  It is preferable that at least one of the upper arm and the lower arm is provided to be extendable.

  One upper nozzle or lower nozzle may be provided on the upper arm or the lower arm.

  The liquid supply pipe system of the upper cleaning mechanism or the liquid supply pipe system of the lower cleaning mechanism includes a cleaning liquid supply pipe system and a rinsing liquid supply pipe system, respectively. It is preferable to have an upper nozzle or a lower nozzle.

  It is preferable to further include a side cleaning mechanism that is disposed on the side of the support frame and ejects liquid from the side to the support frame.

  According to the present invention, the support frame that supports the article is rotated, and the cleaning mechanism jets the cleaning liquid onto the article in the support frame to perform cleaning. The upper arm in the upper support mechanism rotates approximately horizontally above the support frame that rotates approximately horizontally. The lower arm in the lower support mechanism also rotates substantially horizontally below the support frame that rotates approximately horizontally. The present invention has at least one, preferably both, of the upper support mechanism or the lower support mechanism, and the cleaning liquid is supplied from the upper nozzle provided on the upper arm or the lower nozzle provided on the lower arm to the support frame. It is injected toward the body article. Since the support frame rotates approximately horizontally, if the upper nozzle or the lower nozzle rotates approximately horizontally above or below, the support frame is preferably supported from an arbitrary position on the outer periphery (the outermost edge during rotation) of the support frame. When rotating along an arc extending to the vicinity of the center of rotation of the frame, the cleaning liquid can be uniformly sprayed from above or below toward the article accommodated in the support frame to be cleaned.

  For this reason, the number of nozzles required for even cleaning is less than in the prior art. At least, it is provided so as to rotate along an arc extending from an arbitrary position on the outer periphery (the outermost edge at the time of rotation) of the article itself accommodated in the support frame to the vicinity of the rotation center of the article. If this is the case, the minimum number of nozzles required to uniformly inject liquid upward or downward with respect to the article is one for both the upper and lower nozzles. When it is provided so as to rotate along an arc extending from an arbitrary position on the outer periphery (outermost edge during rotation) of the support frame larger than the size of the accommodated article to the vicinity of the rotation center, Regardless of the size, if one nozzle is provided, the liquid can be uniformly sprayed above or below the article to be accommodated. As a result, it is possible to inject at a predetermined momentum even at a low water pressure. As a result, the pump capacity for supplying the cleaning liquid can be reduced, which contributes to energy saving.

  In addition, when the upper arm or the lower arm is provided to be extendable and retractable, the cleaning liquid ejection range can be more appropriately adjusted according to the size and shape of the article, the installation position in the support frame, and the like.

  In addition, by adding a side cleaning mechanism, a cleaning liquid can be ejected from the side of the article, and the cleaning efficiency is further improved.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. As shown in FIG. 1, the article cleaning apparatus 1 of this embodiment includes a cleaning chamber 10, a support frame 20, an upper cleaning mechanism 30 and a lower cleaning mechanism 40 that constitute a cleaning mechanism unit. The

  The cleaning chamber 10 is for cleaning articles 70 such as pallets, containers, etc., such as article transport containers, machine parts and instruments, with a cleaning liquid 60 (cleaning liquid, rinsing liquid, etc.), and has a box shape. Is formed. In the cleaning chamber 10, an opening / closing door 11 for taking in and out the article 70 is provided so as to be movable up and down.

  The support frame body 20 is a frame body on which the article 70 can be placed and supported, and is provided rotatably inside the cleaning chamber 10. The support frame 20 is formed by, for example, forming a plurality of stainless steel solid rods or hollow pipes in a lattice-like cage shape, and ejecting a cleaning liquid 60 on which an article 70 is placed. At this time, the cleaning liquid 60 is configured to be applied to the article 70. In addition, it does not form with a rod or a pipe, but can also form using a net | network. Further, as shown in FIG. 2, the support frame 20 has a substantially rectangular shape in plan view, and the corner portion 22 has a smooth R shape with no corners.

  The support frame 20 is detachably attached to the tip of the rotating shaft 12 provided vertically from the bottom of the cleaning chamber 10. For example, a pin hole 23 is provided at the center of the bottom portion of the support frame 20, and the fixing pin 24 is inserted into the pin hole 23 and the pin mounting hole 13 at the tip of the rotary shaft 12, thereby screwing It can be fixed with. The rotating shaft 12 is configured to be rotationally driven by a rotational driving device such as a motor (not shown) provided at an appropriate position such as the lower side outside the cleaning chamber 10 at the lower end side.

  Further, in order to stabilize the mounting state of the support frame body 20 with respect to the rotating shaft 12, for example, a plurality of receiving members extending radially around the front end portion of the rotating shaft 12 and the front end sides of the plurality of receiving members are provided. A support frame body receiving member 14 composed of a connecting member connected in a ring shape is provided, and a plurality of free casters 15 can be provided on the lower surface of the support frame body receiving member 14 so as to be able to travel on the bottom surface of the cleaning chamber 10. When the support frame body receiving member 14 is rotated by the rotating shaft 12, the free caster 15 rolls annularly along the bottom surface of the cleaning chamber 10, so that the support frame body receiving member 14 and the support frame body 20 supported thereby. Can rotate stably.

  The support frame 20 can be taken out of the cleaning chamber 10 by being configured to be removable with respect to the rotating shaft 12 that rotatably supports the support frame 20. Thereby, when dirt adheres to the support frame body 20 itself, the support frame body 20 can be taken out and easily cleaned. Moreover, since it becomes easy to clean the stain | pollution | contamination adhering to the side wall surface of the cleaning chamber 10 after taking out the support frame 20 from the cleaning chamber 10, it can contribute to keeping cleaning apparatus itself cleaner.

  The cleaning mechanism unit is for cleaning the article 70 supported by the support frame 20 by spraying the cleaning liquid 60, and includes an upper cleaning mechanism 30, a lower cleaning mechanism 40, and a side cleaning mechanism 50.

  As shown in FIGS. 1 and 3, the upper cleaning mechanism 30 includes upper nozzles 31 and 32 and upper arms 33b and 34b. The upper nozzles 31 and 32 eject the cleaning liquid 60 from above the support frame 20 toward the article 70.

  In the present embodiment, the two vertical pipe portions 33 a and 34 a rising vertically are supported by the rotation support portion 38, extend from the upper portion in a substantially horizontal direction, and are positioned above the support frame body 20 so as to be positioned above the support frame body 20. , 34b are provided. In the present embodiment, one vertical pipe portion 33a, one upper arm 33b, and one upper nozzle 31 are formed of a substantially L-shaped integral pipe, and the other vertical pipe portion 34a, the other upper arm 34b, and the other upper nozzle 31 are formed. The upper nozzle 32 is also formed from a substantially L-shaped integral pipe. Then, by supplying the cleaning liquid 61 to one vertical pipe portion 33a, the one vertical pipe portion 33a, the one upper arm 33, and the one upper nozzle 31 constitute a cleaning liquid supply pipe system, By supplying the rinsing liquid to the vertical pipe section 34a, the other vertical pipe section 34a, the other upper arm 34b, and the other upper nozzle 32 constitute a rinsing liquid supply pipe system.

  Since the vertical pipe portions 33a and 34a are supported so as to be horizontally rotatable by the rotation support portion 38 provided at an appropriate position such as the lower outside of the cleaning chamber 10 as described above, the upper arms 33b and 34b The vertical pipe portions 33a and 34a are pivoted substantially horizontally above the support frame body 20.

  The upper cleaning mechanism 30 is not limited to the above structure. For example, in the example shown in FIG. 1 and FIG. 3, each vertical pipe portion 33a, 34a, each upper arm 33b, 34b, and each upper nozzle 31, 32 are each composed of a single substantially L-shaped pipe, A cleaning liquid 60 such as a cleaning liquid 61 or a rinsing liquid 62 is directly passed through the inside. However, as shown in FIG. 5 (A), as the upper arm 35 and the vertical pipe portion (not shown), a thick pipe-like one is prepared, and the liquid 60 is not directly passed therethrough. An upper cleaning liquid supply pipe 36 and an upper rinsing liquid supply pipe 37 made of a flexible tube are arranged, and the two upper nozzles 31 and 32 are connected to the upper cleaning liquid supply pipe 36 and the upper rinsing liquid supply pipe 37 through the support plate 35a. Connect to the tip of the. Then, the rear ends of the upper cleaning liquid supply pipe 36 and the upper rinsing liquid supply pipe 37 are connected to the cleaning liquid tank 63 and the rinsing liquid tank 64, respectively, so that the upper cleaning liquid supply pipe 36 and the upper nozzle 31 connected to the tip of the upper cleaning liquid supply pipe 36 A supply pipe system is configured, and the upper rinse liquid supply pipe 37 and the upper nozzle 32 connected to the tip of the upper rinse liquid supply pipe 37 constitute a rinse liquid supply pipe system.

  In FIG. 5B, the upper arm 35 is formed from a thin pipe or a solid rod-like member, and a support plate 35a is provided at the tip thereof, and the two upper nozzles 31 and 32 are supported on the support plate 35a. An upper cleaning liquid supply pipe 36 and an upper rinsing liquid supply pipe 37 made of a flexible tube or the like similar to FIG. In the case of FIG. 5B, the vertical pipe portion only needs to be able to support the upper arm 35, and may be formed from a thin pipe or a solid rod-shaped member.

  That is, in FIGS. 1 and 3, the upper arms 33 b and 34 b and the vertical pipe portions 33 a and 34 a function not only as members that support the upper nozzles 31 and 32 but also as a cleaning liquid supply pipe system or a rinsing liquid supply pipe system. 5 (A) and 5 (B) support the upper cleaning liquid supply pipe 36 and the upper rinsing liquid supply pipe 37 constituting the cleaning liquid supply pipe system or the rinsing liquid supply pipe system. The upper arm 35 and the vertical pipe part are used as members, and upper nozzles 31 and 32 to which the upper cleaning liquid supply pipe 36 and the upper rinse liquid supply pipe 37 are connected are provided at the tip of the upper arm 35. In any case, the upper arms 33b, 34b, and 35 need only be able to rotate substantially horizontally with the upper nozzles 31 and 32 positioned above the support frame 20, and the configuration is limited to these examples. It is not something.

  As shown in FIGS. 1 and 4, the lower cleaning mechanism 40 includes lower arms 43 and 44 that extend substantially horizontally from the vicinity of the lower portions of the vertical pipe portions 33 a and 34 a in the upper cleaning mechanism 30. The lower arms 43 and 44 are formed of pipes, and lower nozzles 41 and 42 are provided upward at respective tips. The lower arms 43 and 44 are formed of pipes, and are branched from the vertical pipe portions 33a and 34a of the upper cleaning mechanism 30 that are also formed of pipes. In this embodiment, one of the lower arms 43 and the lower nozzle 41 is branched. Constitutes a cleaning liquid supply pipe system, and the other lower arm 44 and lower nozzle 42 constitute a rinse liquid supply pipe system.

  The structures of the lower arms 43 and 44 and the lower nozzles 41 and 42 have a function of passing a liquid while supporting a support plate (not shown) at the tip as in the case of the upper cleaning mechanism 30. A lower arm (not shown) is provided, and the lower nozzles 41 and 42 are supported upward by the support plate. The lower nozzles 41 and 42 are made of a flexible tube or the like, and are provided in the cleaning liquid tank 63 and the rinsing liquid tank 64. A lower cleaning liquid supply pipe (not shown) to which the rear end is connected and a front end of a lower rinsing liquid supply pipe (not shown) may be connected. That is, the configuration in which the upper nozzles 31 and 32 are supported by using the upper arm 35 and the support plate 35a shown in FIGS. 5A and 5B can be configured to be vertically inverted in the drawing.

  Since the lower arms 43 and 44 are branched from the vertical pipe portions 33a and 34a of the upper cleaning mechanism 30 as described above in FIGS. 1 and 3, the vertical pipe portions 33a and 34a are rotated by the rotation support portion 38. As a result, it is rotated around the vertical pipe portions 33a and 34a, which are the base end portions, below the support frame 20. Of course, this is merely an example, and a vertical pipe portion (not shown) separate from the vertical pipe portions 33a and 34a of the upper cleaning mechanism 30 is installed on the rotation support portion 38, and extends substantially horizontally from the vertical pipe portion. Lower arms 43 and 44 may be provided. In that case, the rotation timing of the upper arms 33b and 34b and the rotation timing of the lower arms 43 and 44 may be synchronized, or can be controlled separately at appropriate timing without being synchronized. .

  The upper arms 33b and 34b and the lower arms 43 and 44 support the support frame 20 from above or below the support frame 20 when the support frame 20 rotates substantially horizontally, and when the support frame 20 rotates substantially horizontally above or below the support frame 20. The cleaning liquid can be uniformly supplied to the frame body 20. In this case, as shown in FIG. 2, from the arbitrary position on the outer periphery (the outermost edge at the time of rotation) of the support frame 20, in order to prevent a portion where the cleaning liquid does not hit the support frame 20. The lengths of the upper arms 33b and 34b and the lower arms 43 and 44 are preferably set so as to rotate along an arc extending to the center of rotation of the support frame 20. In addition, when the article to be cleaned is a fixed type and the installation location in the support frame 20 is constant, the support frame 20 from any position on the outer periphery (the outermost edge during rotation) of the article. What is necessary is just to be able to rotate along the circular arc until it reaches the rotation center.

  Further, the lengths of the upper arms 33b and 34b and the lower arms 43 and 44 can be adjusted in accordance with the size of the support frame 20 and the size and shape of the articles accommodated in the support frame 20, as shown in FIG. As shown, the upper arm 300 or the lower arm 400 can be extended and contracted, such as a double-pipe type, so that the radius of rotation can be adjusted.

  In addition, although both the above-mentioned upper support mechanism 30 or lower support mechanism 40 is provided in this embodiment, it can also be set as the structure which provided any at least one. Also, either the upper arm 33b, 34b or the lower arm 43, 44 can be rotated substantially horizontally as described above, and the other can be fixed. However, it goes without saying that both of them are preferably rotatable.

  According to the present embodiment, as described above, the upper arms 33b and 34b or the lower arms 43 and 44 are rotated, so that even if the number of nozzles is small, each arm 33b is minimized as in the present embodiment. , 34b, 43, 44, even if there is only one nozzle 31, 32, 41, 42, the cleaning liquid is uniformly sprayed from above or below toward the articles contained in the support frame. Can be washed. That is, since the number of nozzles required for uniform cleaning can be smaller than in the past (the minimum number of nozzles required is one as in the present embodiment for both the upper nozzle and the lower nozzle), even if the water pressure is low, it is predetermined. Therefore, the pump capacity for supplying the cleaning liquid can be small, and the operation cost can be reduced. Further, when the upper arms 33b and 34b or the lower arms 43 and 44 are rotated, the liquid hits all the parts of the article, so that there is no cleaning leakage. Furthermore, since the number of nozzles ejected by the liquid is small, it is possible to easily grasp the position of the article hit by the liquid, and it is possible to visually confirm that the cleaning is reliably performed at this point. This also leads to a sense of security, and even if there is a part that is insufficiently cleaned, it is possible to visually check and clean the predetermined part.

  The present embodiment includes the upper cleaning mechanism 30 and the lower cleaning mechanism 40 described above as the cleaning mechanism, but preferably includes a side cleaning mechanism 50 in addition to these. Since the side cleaning mechanism 50 is provided, the side of the article can be cleaned at the same time. The side cleaning mechanism 50 only needs to perform such a function. For example, a fixed type can be applied, but in order to minimize unevenness in cleaning the article, the side cleaning mechanism 50 is shown in FIGS. Thus, it is preferable that the side nozzle mechanism 51 supported by the side support mechanism 55 is a swing type.

  The side nozzle mechanism 51 is provided with, for example, two or more nozzle pipes 53, 53,... In order to inject the cleaning liquid 60 from the side surface of the support frame 20 toward the article 70. A plurality of side injection nozzles 52, 52,... Are arranged in each nozzle pipe 53, 53,. The cleaning liquid 61 is supplied to at least one nozzle pipe 53, and the rinsing liquid 62 is supplied to at least one other nozzle pipe 53.

  The side support mechanism 55 elastically biases and supports the side nozzle mechanism 51 in a direction that always approaches the periphery of the support frame 20. In other words, the side support mechanism 55 includes a side support arm 56 and a guide roller 57 as shown in FIGS.

  The side support arm 56 rotates around the base end portion 56a. The guide roller 57 is pivotally supported at the tip of the side support arm 56, can contact the periphery of the support frame 20, and rotates as the support frame 20 rotates. In addition, for example, a tension coil spring 58 is provided as an elastic member that urges the guide roller 57 in a direction that always approaches the periphery of the support frame 20. The side nozzle mechanism 51 is configured to be pivotally supported at the distal end portion of the side support arm 56.

  More specifically, in FIG. 7, a shaft 56 b extending in the vertical direction is integrally connected to a distal end portion of a side support arm 56 having two arm members arranged vertically, and the shaft 56 b A guide roller support member 56c having a U-shaped cross-section that is pivotally supported on the top and bottom is disposed vertically. Two guide rollers 57 are rotatably provided on the upper and lower guide roller support members 56c. The upper and lower guide rollers 57 are provided at positions that always contact the outside of the support frame 20.

  Between the upper and lower guide roller support members 56c, at least two nozzle pipes 53 constituting the side nozzle mechanism 51 are arranged in parallel so as to extend vertically. Among them, some of the nozzle pipes 53 are connected to a cleaning liquid tank 63 (cleaning liquid storage section) to eject the cleaning liquid 61, and the other nozzle pipes 53 are connected to a rinsing liquid tank 64 (rinsing liquid storage section) to rinse. The liquid 62 can be ejected. Each nozzle pipe 53 has a plurality of side injection nozzles 52, 52,... In FIG.

  Further, the side support arm 56 is extended from a hook 59 or the like provided at a location located outside the rotation trajectory of the support frame 20 by a tension coil spring 58 (elastic member). Each of the upper and lower guide rollers 57 provided in the section is urged in a direction that always contacts the outside of the support frame 20. Other methods for biasing the side support arms 56 are not limited to this.

  As shown in FIG. 1, a cleaning liquid tank 63 (cleaning liquid storage section) for storing the cleaning liquid 61 and a rinsing liquid tank 64 (rinsing liquid storage for storing the rinsing liquid 62) are disposed at appropriate positions such as outside the cleaning chamber 10. Part). The cleaning liquid 61 in the cleaning liquid tank 63 is supplied to the upper cleaning mechanism 30, the lower cleaning mechanism 40, and the side cleaning mechanism 50 by the cleaning liquid supply pump 65, and the rinsing liquid 62 in the rinsing liquid tank 64 is supplied to the upper part by the rinsing liquid supply pump 66. It is supplied to the cleaning mechanism 30, the lower cleaning mechanism 40, and the side cleaning mechanism 50.

  The side nozzle mechanism 51 is configured to be urged by the side support mechanism 55 in a direction in which the side nozzle mechanism 51 always approaches the periphery of the support frame 20. As a result, the side injection nozzle 52 is always in contact with the periphery of the support frame 20, and the separation distance between both faces the vicinity of each corner portion 22 even when facing the vicinity of each side portion 21. It will be almost the same. For this reason, the cleaning pressure of the cleaning liquid 60 is substantially the same without depending on the rotational position of the support frame 20, and cleaning unevenness is reduced.

  Further, by adopting a configuration in which the side nozzle mechanism 51 is pivotally supported at the tip of the side support arm 56, when the side support arm 56 is elastically biased and pressed against the support frame 20, the side portion The spray nozzle 52 always faces the outer periphery of the support frame 20 regardless of the rotation angle of the support frame 20. Therefore, even when two articles 70 are stored vertically in a back-to-back manner, there is no blind spot where the cleaning liquid 60 does not hit. For example, as shown in FIG. 2, in the state where the side spray nozzle 52 faces the vicinity of the side portion 21 of the support frame 20, the cleaning liquid 60 sprayed from the side spray nozzle 52 is that of the article 70. Injected at the closest distance to the inside. As shown in FIGS. 8A and 8B, in the state in which the side spray nozzle 52 is positioned near the corner portion 22 of the support frame 20, the cleaning liquid 60 sprayed from the side spray nozzle 52 is as follows. There is no blind spot with respect to the inner corner of the article 70. As described above, by adopting a configuration in which the side nozzle mechanism 51 is pivotally supported at the distal end portion of the side support arm 56, the cleaning unevenness can be further reduced.

  If the extendable upper and lower arms 300 and 400 as shown in FIG. 6 are employed, they are appropriately extended and retracted as shown by solid lines and two-dot chain lines in FIGS. 8A and 8B. Thus, the cleaning range can be adjusted, and the supply range of the cleaning liquid supplied from above or below can be adjusted in accordance with the shape of the article to be cleaned, etc., and cleaning unevenness can be further reduced.

  In the above description, two upper nozzles 31 and 32 and two lower nozzles 41 and 42 are provided to constitute a cleaning liquid supply pipe system and a rinsing liquid supply pipe system, respectively. The pipe system can be a plurality of systems both in the upper part and in the lower part. In addition, each of the upper nozzle and the lower nozzle is set to one, that is, only one liquid supply pipe system for supplying the cleaning liquid is supplied, and the cleaning liquid is supplied first through the liquid supply pipe system, and then rinsed. It is also possible to supply liquid. In the above description, in FIGS. 2 and 8, an article transport container such as a substantially box-like pallet is shown as an article to be cleaned. The present invention is suitable as an apparatus for cleaning without any problems.
