JP-A-1-115465 JP-A-1-202558

However, when the object to be cleaned is large or has a complicated structure, it is difficult to automate the cleaning work. In other words, it may be difficult to automate the cleaning work because the transport mechanism for the object to be cleaned becomes large-scaled or interference occurs between the object to be cleaned and the nonwoven fabric.

In such a case, an operator has to manually perform the cleaning work. However, volatile cleaning agents are generally harmful to the human body, and workers wear masks to perform cleaning work. Therefore, it is necessary to give sufficient consideration to ensuring safety.

(Structure and function of cleaning equipment)
FIG. 1 is a side view of a cleaning device according to an embodiment of the present invention, and FIG. 2 is a front view of the cleaning device shown in FIG. In FIG. 2, illustration of an object to be cleaned is omitted.

The cleaning device 1 is a device that automatically cleans an object O to be cleaned using a cleaning agent. Specifically, the cleaning device 1 has a function of automatically applying a cleaning agent to the object O and wiping off the cleaning agent applied to the object O. As shown in FIG. A cleaning method for cleaning the object O by applying and wiping off a cleaning agent is also called a double-wipe cleaning method.

Double-wipe cleaning is often performed for the purpose of dissolving and removing dirt containing oil components before painting. For this reason, cleaning agents are sometimes referred to as solvents. The primary cleaning agents used in double wipe cleaning include methyl ethyl ketone (MEK), methyl propyl ketone (MPK), methyl alcohol, ethyl alcohol and acetone. Examples of the material of the object O to be cleaned include not only metals such as aluminum and iron, but also glass fiber reinforced plastics (GFRP) and carbon fiber reinforced plastics (CFRP). and resins such as plastics.

FIG. 3 is a perspective view showing a structural example of the object O to be cleaned shown in FIG.

As illustrated in FIG. 3, the surface of a plate-like object O to which two elongated structures O1 are attached can be cleaned by the cleaning device 1. FIG. Each elongated structure O1 has a planar web and a flange whose width changes in the longitudinal direction, and has an I-shaped cross section. A structure having such a structure includes an aircraft structure in which reinforcing members such as ribs, spars, or stringers are attached to panels. Of course, the cleaning device 1 can clean a flat surface of the object O without unevenness or a curved surface of the object O with a small curvature.

The cleaning apparatus 1 can be configured by attaching a cleaning agent tank 3, a gantry 4 and a head 5 to a housing 2 as shown in FIGS. A first nonwoven cotton 6 and a second nonwoven cotton 7 are attached to the head 5 . The first non-woven cotton 6 is a non-woven fabric for applying a cleaning agent to the object O to be cleaned. On the other hand, the second non-woven cotton 7 is a non-woven fabric for wiping off the cleaning agent applied to the object O to be cleaned. The non-woven fabric is a sheet-shaped fabric in which fibers are intertwined without being woven, and the non-woven cotton is a non-woven fabric made of cotton.

FIG. 4 is a perspective view showing a detailed structural example of the housing 2 and the gantry 4 shown in FIG.

The housing 2 is a container for fixing the gantry 4 and the object O to be cleaned. The housing 2 can be, for example, a frame structure. In the example shown in FIG. 1, the housing 2 is provided with a frame 2A for fixing the object O to be cleaned.

The cleaning agent tank 3 is a tank for storing and supplying a cleaning agent. Therefore, the detergent tank 3 is connected with a supply pipe 3A for supplying the detergent to the first non-woven cotton 6 . Since the surface tension of the first non-woven cotton 6 is large, the cleaning agent is easily impregnated into the first non-woven cotton 6 simply by dropping the cleaning agent onto the first non-woven cotton 6 from the supply pipe 3A. be able to.

The gantry 4 is a support mechanism that supports the head 5 to which the first nonwoven cotton 6 and the second nonwoven cotton 7 are attached. The gantry 4 functions as a moving mechanism for moving the head 5 on which the first nonwoven cotton 6 and the second nonwoven cotton 7 are attached, relative to the object O. As shown in FIG. In the example shown in FIGS. 1 and 4, the gantry 4 is provided with a moving mechanism 4A for moving the head 5 in the vertical direction. The vertical direction from top to bottom is the feeding direction F of the head 5 on which the first non-woven cotton 6 and the second non-woven cotton 7 are attached.

When the feeding direction F of the head 5 is only the vertical direction, the moving mechanism 4A, for example, as shown in FIG. It can be simply configured by a ball screw 4C that moves in parallel, a motor 4D that rotates the ball screw 4C, and a linear guide 4E that guides the mounting plate 4B. Of course, instead of the ball screw 4C, a rack and pinion or a cylinder mechanism may be used to linearly translate the mounting plate 4B.

When the range of the surface to be cleaned of the object O to be cleaned is so wide that it cannot be covered only by moving the first non-woven cotton 6 and the second non-woven cotton 7 in the vertical direction, the first non-woven cotton 6 and the second non-woven cotton 7 If the distance between the second nonwoven cotton 7 and the cleaning surface of the object O varies, the gantry 4 can also be provided with a movement mechanism for moving the head 5 in the horizontal direction. That is, a moving mechanism for moving the head 5 in the horizontal direction perpendicular to the cleaning surface of the object O to be cleaned, and a mechanism for moving the head 5 in the horizontal direction parallel to the cleaning surface of the object O to be cleaned. can also be provided in the gantry 4.

However, if the object O is washed downward from above, the object O can be washed while the adherents and solid adherents separated by the cleaning agent are dropped downward. Therefore, if the gantry 4 has a single-axis structure that moves the head 5 only in the vertical direction as illustrated in FIGS. The structure of the gantry 4 can be dramatically simplified. As a result, the cost effectiveness of the cleaning apparatus 1 that does not involve processing the object O can be improved.

Further, the housing 2 may be provided with a moving mechanism for moving the object O to be cleaned. That is, the cleaning apparatus 1 is provided with a moving mechanism for moving at least one of the head 5 and the object O like the moving mechanism 4A, and the head 5 to which the first nonwoven cotton 6 and the second nonwoven cotton 7 are attached is moved to the object. It can be moved relative to O. Even in that case, reduction in the number of drive shafts leads to simplification of the structure of the cleaning device 1 .

However, as shown in the figure, the object O to be cleaned is fixed to the housing 2, and the head 5 on which the first non-woven cotton 6 and the second non-woven cotton 7 are attached is moved by the moving mechanism 4A. With this configuration, a moving mechanism for moving the object O to be cleaned becomes unnecessary. In particular, since the head 5 to which the first non-woven cotton 6 and the second non-woven cotton 7 are attached can be easily reduced in weight, the rigidity required for the moving mechanism 4A for moving the head 5 is In many cases, the rigidity is smaller than the rigidity required for the movement mechanism for moving the object O. Therefore, if the object O to be cleaned is fixed to the housing 2 and the head 5 is moved by the moving mechanism 4A, the structure of the cleaning device 1 can be simplified. This effect is particularly remarkable when the object O to be cleaned is large or the weight of the object O to be cleaned is large.

It is preferable that the relative feed speed between the head 5 and the object O is as high as possible from the viewpoint of improving the cleaning efficiency. In addition, when the first non-woven cotton 6 applies a volatile cleaning agent to the location to be cleaned of the object O, the cleaning agent applied to the location to be cleaned evaporates. It is essential to determine the relative feed speed between the head 5 and the object O such that the cleaning agent previously applied to the location to be cleaned is wiped off by the second nonwoven cotton 7. .

When the cleaning agent has volatility, the appropriate relative feeding speed between the head 5 and the object O depends on the application position of the cleaning agent by the first non-woven cotton 6 and the cleaning agent application position by the second non-woven cotton 7. In addition to the dominant conditions such as the distance from the wiping position, the amount of cleaning agent impregnated in the first non-woven cotton 6, the type of cleaning agent and the material of the object O, cleaning such as temperature, humidity and atmospheric pressure. It is believed that it will also change depending on various conditions, including atmospheric conditions. Therefore, an appropriate relative feed speed between the head 5 and the object O can be determined by a test that simulates actual cleaning conditions. A small amount of the cleaning agent impregnated in the first non-woven cotton 6 leads to a reduction in consumables, so it is preferable to use a small amount.

The head 5 functions as a holding mechanism that holds the first non-woven cotton 6 and the second non-woven cotton 7 at regular intervals. Since the first non-woven cotton 6 is a non-woven cotton for applying a cleaning agent to the surface of the object O to be cleaned, the feeding direction of the head 5 relative to the second non-woven cotton 7 F is held on the destination side. Conversely, since the second non-woven cotton 7 is a non-woven cotton for wiping off the cleaning agent applied to the surface of the object O, the head 5 is It is held on the sending side in the sending direction F.

Therefore, as illustrated in FIGS. 1 and 2, when the feeding direction F of the head 5 on which the first nonwoven cotton 6 and the second nonwoven cotton 7 are attached is vertically downward, the first The nonwoven cotton 6 is arranged below the second nonwoven cotton 7 , while the second nonwoven cotton 7 is arranged above the first nonwoven cotton 6 .

The distance between the first nonwoven cotton 6 and the second nonwoven cotton 7 is such that the cleaning agent applied to the surface of the object O by the first nonwoven cotton 6 reaches the second nonwoven before evaporation. It is determined according to the relative feed speed between the head 5 and the object O so that the cotton 7 can be wiped off.

The material of the head 5 is preferably a material that does not damage the object O to be cleaned and is not corroded by the cleaning agent even if it collides with the object O to be cleaned. Therefore, the head 5 can be made of a resin such as polyacetal, which has a lower hardness and corrosion resistance than the object O, for example.

The head 5 can also be configured to rotatably hold the first nonwoven cotton 6 and the second nonwoven cotton 7 around the first roller 8 and the second roller 9, respectively. . That is, the first nonwoven cotton 6 and the second nonwoven cotton 7 can be wound around a cylindrical or columnar first roller 8 and a second roller 9, respectively, attached to the head 5. As shown in FIG.

The directions of the rotation axes of the first roller 8 and the second roller 9 are determined by the direction in which the first non-woven cotton 6 and the second non-woven cotton 7 are pressed against the object O, and the direction in which the movement mechanism 4A is driven. A direction perpendicular to both the directions in which the first nonwoven 6 and the second nonwoven 7 move relative to the object O during washing of the object O is suitable.

That is, by setting the rotation axes of the first roller 8 and the second roller 9 in directions perpendicular to both the pressing direction P and the feeding direction F, the first nonwoven cotton 6 and the second nonwoven cotton When the nonwoven cotton 7 of is moved in the feeding direction F while being pressed against the surface of the object O in the pressing direction P, between the first nonwoven cotton 6 and the second nonwoven cotton 7 and the object O The first roller 8 and the second roller 9 can be rotated without being powered by frictional force. Then, while rotating the first roller 8 and the second roller 9, the application of the cleaning agent with the first non-woven cotton 6 and the wiping off of the cleaning agent with the second non-woven cotton 7 are continuously performed. be able to.

The first roller 8 and the second roller 9 can be attached to the head 5 in any manner. For example, each rotating shaft of the first roller 8 and the second roller 9 can be connected to a frame fixed to the head 5 with fasteners such as screws.

In the example shown in FIG. 2, a plurality of first rollers 8 each having a first nonwoven cotton 6 wound thereon are arranged in a row in the horizontal direction. Similarly, second rollers 9, each wrapped with a second nonwoven cotton 7, are arranged horizontally in a row. By arranging the plurality of first non-woven cottons 6 and the plurality of second non-woven cottons 7 according to the size of the object O to be cleaned in this way, the first non-woven cottons 6 and the second non-woven cottons 7 can be arranged. Even if the object O has a wider width than the standard width of the non-woven cotton 7, the cleaning area can be cleaned by moving the first non-woven cotton 6 and the second non-woven cotton 7 only in one axial direction. can be covered.

Also, if a plurality of first non-woven cottons 6 and a plurality of second non-woven cottons 7 are spaced apart, the object O to which the elongated structure O1 as illustrated in FIG. Also, the first non-woven cotton 6 and the second non-woven cotton 7 can be moved in the feed direction F without interfering with the elongated structure O1. Furthermore, the first non-woven cotton 6 and the second non-woven cotton 6 and the second non-woven cotton are placed in appropriate positions and directions so that the cleaning agent can be applied and wiped off on the outer and inner surfaces of the elongated structure O1. 7 can also be placed. In that case, the shape and structure of the head 5 are determined so that the first non-woven cotton 6 and the second non-woven cotton 7 can be arranged at positions where they can be brought into contact with the surface of the elongated structure O1. do it.

A brush 10 is preferably provided between the first non-woven cotton 6 and the second non-woven cotton 7 and the first roller 8 and the second roller 9 . In other words, the first nonwoven cotton 6 and the second nonwoven cotton 7 can be wound onto a brush 10 attached to the first roller 8 and the second roller 9 respectively.

FIG. 5 shows an example in which the first nonwoven cotton 6 and the second nonwoven cotton 7 shown in FIG. It is a cross-sectional view.

As shown in FIG. 5, a first non-woven cotton 6 and a second non-woven cotton 7 are wound around a first roller 8 and a second roller 9 having brushes 10, respectively, so as to remove the cleaning agent. A coating pad 20 and a wiping pad 21 may be configured.

Then, it becomes possible to press the first non-woven cotton 6 and the second non-woven cotton 7 against the surface of the object O to be cleaned while the brush 10 is bent. As a result, even if there is a relative positioning error between the head 5 and the object O, the elasticity of the brush 10 can absorb the positioning error. Further, even when the surface of the object O to be cleaned is curved or uneven, the elasticity of the brush 10 enables double-wipe cleaning.

As a specific example, a first non-woven cotton 6 and a second non-woven cotton 7 are wound around a first roller 8 and a second roller 9 implanted with a brush 10 having a hair length of 10 mm or more, and the brush 10 is wound. When the first non-woven cotton 6 and the second non-woven cotton 7 are pressed against the surface of the object O to be cleaned while being bent by about 5 mm, the elasticity of the brush 10 absorbs the positioning error of ±5 mm. be able to. In addition, it is possible to perform double-wipe cleaning of a curved surface that curves within a range of ±5 mm or a surface that has irregularities.

As the material of the brush 10, it is appropriate to use a material such as a resin that can maintain its restoring force even when it is bent for a certain period of time while being soaked in a cleaning agent.

Furthermore, the first non-woven cotton 6 and the second non-woven cotton 7 are slid in the direction in which the first non-woven cotton 6 and the second non-woven cotton 7 are pressed against the object O, that is, the pressing direction P. It can be attached to the head 5 whenever possible. Then, not only the elasticity of the brush 10 but also the sliding of the first non-woven cotton 6 and the second non-woven cotton 7 can cancel the relative positioning error between the head 5 and the object O. . Alternatively, when the surface of the object O is not flat, it is possible to finely adjust the distance between the surface of the object O and the first nonwoven cotton 6 and the second nonwoven cotton 7 . Therefore, it is possible to reduce the positioning accuracy and the number of drive shafts required for the moving mechanism provided in the gantry 4 . As a result, the cost of the gantry 4 can be reduced.

Moreover, excessive deformation of the brush 10 due to an excessively small distance between the head 5 and the object O can be avoided. That is, the distance between the head 5 and the object O can be made to follow the position of the object O so that the amount of deformation of the brush 10 is always within a certain range. Therefore, it is possible to reduce consumption of the brush 10 and increase its life.

In addition, the direction perpendicular to both the pressing direction P and the feeding direction F of the first nonwoven cotton 6 and the second nonwoven cotton 7 against the object O, that is, the first nonwoven cotton 6 and the second nonwoven cotton 7 The first non-woven cotton 6 and the second non-woven cotton 7 are slidable also in the direction parallel to the rotation axis of the first roller 8 and the second roller 9 around which the non-woven cotton 7 is wound. may

In that case, it is also possible to slide the first non-woven cotton 6 and the second non-woven cotton 7 along the outline of the object O to be cleaned. That is, it is possible to clean the surface of the plate-like object O while sliding the first non-woven cotton 6 and the second non-woven cotton 7 along the outline of the object O to be cleaned. As a specific example, as illustrated in FIG. , it is possible to perform double-wipe cleaning while sliding the first non-woven cotton 6 and the second non-woven cotton 7 along the web surface forming the contour of the elongated structure O1. Become.

Alternatively, the positions of the first non-woven cotton 6 and the second non-woven cotton 7 in the direction parallel to the rotation axes of the first roller 8 and the second roller 9 can be fine-tuned before the start of double-wipe cleaning. so as to fix the position of the first nonwoven cotton 6 and the second nonwoven cotton 7 in the direction parallel to the axis of rotation of the first roller 8 and the second roller 9 during double wipe cleaning. can be

In that case, the relative positioning error between the head 5 and the object O in the direction parallel to the rotation axes of the first roller 8 and the second roller 9 can be cancelled. Also, it is possible to double-wipe clean objects O having different shapes within a range where the first non-woven cotton 6 and the second non-woven cotton 7 can be slid. Therefore, even if a minor design change is made to the object O to be cleaned, the first non-woven cotton 6 and the second non-woven cotton 7 can be transferred to the first roller 8 and the second roller 9. Double-wipe cleaning can be performed simply by sliding in a direction parallel to the rotation axis.

The slide function in the pressing direction P of the first non-woven cotton 6 and the second non-woven cotton 7 against the object O is also made slidable for fine adjustment before the start of the double-wipe cleaning, and during the double-wipe cleaning. may be fixed.

FIG. 6 is a front view showing a specific structural example of the head 5 having a structure for slidably attaching the first non-woven cotton 6 and the second non-woven cotton 7 shown in FIG. 1, and FIG. 6 is a top view of the head 5 shown in FIG. 6, and FIG. 8 is a side view of the head 5 shown in FIG.

As illustrated in FIGS. 6 to 8, by connecting the parts constituting the head 5 with long holes 30A and 30B and bolts 31A and 31B inserted into the long holes 30A and 30B, the first non-uniformity is achieved. The woven cotton 6 and the second non-woven cotton 7 can be slidably held.

In the examples shown in FIGS. 6 to 8, the elongated holes 30A in which the length in the pressing direction P of the first non-woven cotton 6 and the second non-woven cotton 7 against the object O is long, and the first non-woven cotton A direction perpendicular to both the pressing direction P of the woven cotton 6 and the second non-woven cotton 7 against the object O and the feeding direction F of the first non-woven cotton 6 and the second non-woven cotton 7, that is, the second Elongated holes 30B, which are elongated in the direction parallel to the rotation shafts of the first roller 8 and the second roller 9, are formed in a plurality of parts such as L-shaped angles constituting the head 5, respectively. By inserting bolts 31A and 31B into the long holes 30A and 30B, the parts of the head 5 and the parts of the head 5 and the mounting plate 4B of the moving mechanism 4A for mounting the head 5 can be connected. . In other words, holes for inserting bolts 31A and 31B for connecting parts of the head 5 are long holes 30A and 30B.

Therefore, the head 5 is configured to hold the first nonwoven cotton 6 and the second nonwoven cotton 7 slidably in the pressing direction P. As shown in FIG. That is, the cleaning agent application pad 20 and the wiping pad 21, which are configured by winding the first non-woven cotton 6 and the second non-woven cotton 7 around the first roller 8 and the second roller 9, respectively, It can be slid in the pressing direction P of the application pad 20 and the wiping pad 21 .

In addition, the head 5 is configured to hold the first nonwoven cotton 6 and the second nonwoven cotton 7 slidably in directions perpendicular to both the pressing direction P and the feeding direction F. ing. That is, a cleaning agent application pad 20 and a wiping pad 21 configured by winding a first nonwoven cotton 6 and a second nonwoven cotton 7 around a first roller 8 and a second roller 9, respectively, It can be slid in a direction parallel to the rotation axes of the first roller 8 and the second roller 9 .

For example, the bolts 31A and 31B inserted into the long holes 30A and 30B may be provided with collars having a diameter that fits the long holes 30A and 30B, or the bolts 31A and 31B inserted into the long holes 30A and 30B may be attached to the bolts 31A and 31B. , the first non-woven cotton 6 and the second non-woven cotton 7 can be slid during double-wipe cleaning by using pin bolts having a diameter that fits the long holes 30A and 30B. On the other hand, when fixing during double-wipe cleaning, the bolts 31A and 31B inserted into the long holes 30A and 30B can be configured by bolts such as simple hexagonal bolts without a positioning function, and can be fixed with nuts. .

As illustrated in FIG. 3, a plate-like object O to which a long structure O1 having a flange and a web is attached is to be cleaned, and the web surface of the long structure O1 is the coating pad 20 and the wiping surface. In the case of being parallel to the feed direction F of the pad 21, the pressing direction P of the application pad 20 and the wiping pad 21 allows the application pad 20 and the wiping pad 21 to slide during double-wipe cleaning, while the first In the direction parallel to the rotation axis of the roller 8 and the second roller 9, fixing the application pad 20 and the wiping pad 21 so as not to slide during double-wipe cleaning is important for the web surface of the elongated structure O1. This is preferable from the viewpoint of enabling double-wipe cleaning to every corner including the corner formed at the connecting portion with the plate-like object O.

Further, when a plate-like object O to which a long structure O1 having a flange and a web is attached as illustrated in FIG. 3 is to be cleaned, as illustrated in FIGS. The shape and structure of the head 5 can be determined so that the head 5, the application pad 20 and the wiping pad 21 do not interfere with the elongated structure O1 even when the pad 20 and the wiping pad 21 are relatively moved in the feed direction F. necessary. In the examples shown in FIGS. 6 to 8, the cross section of the elongated structure O1 is adjusted so that the head 5 does not collide with the elongated structure O1 even when the application pad 20 and the wiping pad 21 are relatively moved in the feed direction F. The head 5 is divided according to the shape of , and a gap is formed.

(Washing method using a washing device)
Next, a cleaning method for obtaining the object O after cleaning by double-wiping cleaning the object O before cleaning using the cleaning apparatus 1 will be described.

When cleaning the object O before cleaning using the cleaning apparatus 1 illustrated in FIG. is placed vertically above. On the other hand, an object O to be cleaned is fixed to the housing 2 with a frame 2A.

Then, the detergent is supplied from the detergent tank 3 to the first non-woven cotton 6 of the application pad 20 through the supply pipe 3A. That is, the first non-woven cotton 6 is impregnated with a detergent. Thereby, the double-wipe cleaning of the object O to be cleaned can be started.

When starting double-wipe cleaning, the moving mechanism 4A is driven. In other words, the application pad 20 and the wiping pad 21 are moved downward from the initial upper position by driving the moving mechanism 4A. Therefore, the application pad 20 and the wiping pad 21 are pressed against the surface of the object O in the pressing direction P, and the frictional force between the first nonwoven cotton 6 and the second nonwoven cotton 7 and the surface of the object O causes the first roller 8 and the second roller 9 to rotate. As a result, the first non-woven cotton 6 and the second non-woven cotton 7 wound around the first roller 8 and the second roller 9 rotate along the surface of the object O in the feed direction F. Moving.

Since the first non-woven cotton 6 is impregnated with the cleaning agent, the surface of the object O against which the first non-woven cotton 6 is pressed is coated with the cleaning agent. As a result, dirt is released from the portion of the surface of the object O to which the cleaning agent is applied.

On the other hand, the second non-woven cotton 7, which is pressed against the surface of the object O after the first non-woven cotton 6 is pressed, is pressed against the surface of the object O in a sufficiently dried state. Therefore, along with the cleaning agent applied to the surface of the object O, the dirt released by the cleaning agent is wiped off by the second non-woven cotton 7 .

Then, the application pad 20 and the wiping pad 21 are moved downward by driving the moving mechanism 4A, and when the wiping pad 21 passes the area of the object O to be cleaned, the double wipe cleaning of the object O is completed. That is, by double-wiping the object O before cleaning, the object O after cleaning can be obtained.

For example, as illustrated in FIG. 3, when the object O to be cleaned is a plate-like object O to which a long structure O1 is attached, a plurality of first nonwoven cottons 6 and second The non-woven cotton 7 can be used to double-wipe clean the surface of the plate-like object O from both sides of the elongated structure O1.

(effect)
The cleaning apparatus 1 and the cleaning method described above automate the double-wipe cleaning in which the cleaning agent is applied and wiped off. Therefore, according to the cleaning device 1 and the cleaning method, the labor required for double-wipe cleaning can be dramatically reduced. Also, even if the volatile cleaning agent is harmful to the operator, the operator can be isolated from the vapor of the cleaning agent, so double-wipe cleaning can be performed safely. In addition, since the time difference between the application of the cleaning agent and the wiping off can be controlled, the operator's experience-based skill is not required. As a result, quality can be stabilized.
