The nip roll 15a is a roll that grips the wiping member 23 with a force equal to or greater than the torque of the first torque motor 11b.
Specifically, this gripping force is generated by the second roll 15ab, which is the other roll of the nip roll 15a, the spring member 15ac tensioning the second roll 15ab, and the first roll 15aa. There is.

Further, when the geared motor 15b wants to drive the drive roll 15, that is, when the first roll 15aa is rotated, the wiping member 23 is moved to the take-up roll 17 side with a force equal to or greater than the torque of the first torque motor 11b. It is a motor to transfer.
The first roll 15aa is preferably provided with a member having excellent frictional properties on its surface in order to stably perform the gripping operation and the transfer operation of the wiping member 23. The first and second rolls 15aa and 15ab and the spring member 15ac constituting the nip roll 15a are selected from known ones.
Further, it is preferable that the geared motor 15b be driven by a predetermined signal sent from a control means such as a sequencer or a computer to these motors in a wired or wireless manner.
This is because the wiping member can be transferred unattended and stably for a long time.
Such control means may be built in the wiping device, or may be provided on a moving means for mounting the wiping device, for example, on the robot side.
A specific example of the DC type geared motor 15b can be selected from, for example, the geared motor VG series (trade name) manufactured by Oriental Motor, although not limited thereto.

4. Take-up Roll The take-up roll 17 is a member for taking up the wiping member 23 transferred by the drive roll 15. The winding roll 17 of this embodiment is preferably a member including a bobbin-shaped roll portion 17a and a second torque motor 17b.
The second torque motor 17b is connected to the shaft of the bobbin-shaped roll portion 17a, has a torque equal to or greater than the torque that can wind the wiping member 23 fed from the drive roll 15, and has a torque adjusting means (not shown). ) Is provided.
It is preferable to use a bobbin-shaped roll portion because it is easy to prevent the tape-shaped wiping member 23 from meandering. The bobbin-shaped roll portion 17a is preferably made of a lightweight material such as resin or aluminum. However, it is preferable to select the material according to the usage environment of the wiping device.
The reason for this is that the wiping device itself can be made lighter in weight, the load on the moving device such as the robot can be reduced, and the operating speed of the operating arm of the robot can be easily increased.
The bobbin-shaped roll portion 17a is a member that can be attached to and detached from the wiping device 10, and after winding the wiping member 23 used for the wiping operation, a new empty bobbin-shaped roll portion 17a is formed. It can be exchanged for 17a.

This is because the wiping member can be transferred unattended and stably for a long time.
Such control means may be built in the wiping device, or may be provided on a moving means for mounting the wiping device, for example, on the robot side.
A specific example of the second torque motor 17b is not limited to this, but can be selected from the torque motor TM series (trade name) manufactured by Oriental Motor, for example.

5. Roll Loading Unit Next, an embodiment of the roll loading unit 19 will be described.
The roll mounting portion 19 is a member in which the unwinding roll 11, the driving roll 15, and the winding roll 17 are arranged. Further, the roll mounting portion 19 is provided with a proper number of columnar guide members 22 in appropriate places as guide members 22 for guiding the conveyance of the wiping member 23.

The material of the roll mounting portion 19 is made of a lightweight material, for example, a frame made of an aluminum material, a titanium material, a ceramic material, a resin material (including a glass fiber reinforced resin or a carbon fiber reinforced resin), or the like. good.
Among these materials, the aluminum material is particularly preferable because it has advantages that it is easy to process, the price is low, and a predetermined strength can be obtained.
However, it is also preferable to select a material having excellent chemical resistance and corrosion resistance, for example, a stainless material, depending on the usage environment of the wiping device.
The total length L0 (see FIG. 3) of the wiping device 10 is, for example, 350 to 600 mm, and the dimensions of the roll mounting portion 19 are such that the length L1 (see FIG. 3) is 250 to 500 mm and the width W1 is It is 50 to 150 mm.

Next, the positional relationship among the unwinding roll 11, the driving roll 15, and the winding roll 17 provided in the roll mounting portion 19 will be described.
In the wiping device 10, the unwinding roll 11, the driving roll 15, and the winding roll 17 are linearly arranged on the roll mounting portion 19.
That is, as shown in FIG. 4, the distance between the virtual straight line M and each of the center points P1, P2, P3 in the width direction (see FIG. 4) of the unwinding roll 11, the driving roll 15, and the winding roll 17 is , The width of each of the unwinding roll, the driving roll, and the winding roll, that is, within a distance of half or less of its own width Wa, Wb, Wc (see FIG. 4), the unwinding roll, the driving roll, and the winding roll. Is preferably arranged.
The reason for this is that if the width of the roll mounting portion 19 is restricted in the width direction with the upper limit of half of the width of the roller itself, the influence of the roll mounting portion 19 expanding in the width direction on the wiping operation can be suppressed.
The distance between each of P1, P2, and P3 and the virtual straight line M is more preferably, for example, one fourth or less, and most preferably all of them are located on the virtual straight line M.

Furthermore, the wiping head 13 is also preferably arranged linearly with respect to the unwinding roll 11, the driving roll 15, and the winding roll 17.
That is, as shown in FIG. 4, the distance between the center point P4 of the wiping head 13 in the width direction W and the imaginary straight line M is within the width of the wiping head, that is, half or less of the width Wd of itself. The wiping head is preferably arranged so that
The reason for this is that it is possible to further prevent the unwinding roll, the driving roll, and the winding roll from interfering with the wiping operation of the object to be wiped.
Further, the distance between P4 and the virtual straight line M is more preferably equal to or less than ¼, and most preferably located on the virtual straight line M.

With such an arrangement relationship, the width W1 of the roll mounting portion 19 becomes the minimum necessary size, and thus the risk of the roll mounting portion 19 coming into contact with the wiping target 25 can be reduced as compared with the conventional case.
That is, even if the wiping target 25 has various forms such as a small size and a complicated shape, a desired wiping operation can be performed without the roll mounting portion 19 coming into contact with the wiping target 25.
Therefore, it is possible to realize a wiping device having high applicability to various types of wiping objects.

6. Arm Unit Next, the configuration of the arm unit 21 will be described.
The arm portion 21 is a member protruding from the roll mounting portion 19 to the outside. Further, a wiping member 23 is suspended from the roll mounting portion 19 via the arm portion 21 to the wiping head 13.
Further, in order to stably transfer the wiping member 23 in the arm portion 21, the wiping member is conveyed to the arm portion 21 on the primary side path and the secondary side path of the wiping member 23, respectively. There is provided at least one guide member 22 for guiding the.

More specifically, the arm portion 21 is provided with three guide members 22 on each of the primary side path and the secondary side path of the wiping member 23, and the wiping member 23 is provided on these guide members. Is properly suspended.
Of course, the number and arrangement of the guide members 22 can be set to a suitable number according to various uses, but for example, it is preferably in the range of 4 to 50, and preferably 6 to 20.
These guide members 22 can be formed of, for example, columnar or columnar members.

Further, the material of the arm portion 21 is preferably a frame made of a lightweight material, such as aluminum, titanium, or resin, similar to the roll mounting portion 19.
Aluminum is particularly preferable because it has advantages such as easy processing, low cost, and a predetermined strength.
However, it is also preferable to select a material having excellent chemical resistance, for example, stainless steel, depending on the usage environment of the wiping device.

Regarding the dimension of the arm portion 21, it is usually preferable that the width W2 (see FIG. 3) is 10 to 40 mm and the length L2 (see FIG. 3) is 50 to 150 mm.
However, the length L1 is preferably a dimension including a portion near the boundary between the arm portion 21 and the roll mounting portion 19 where the reinforcing member 27 (see FIG. 1) having a triangular shape in plan view is provided.
Since the reinforcing member 27 is designed so that it does not substantially affect the object to be wiped 25, there is no problem even if the reinforcing member 27 is included in the dimension L1.
The weight of the wiping device 10 is 3 to 10 kg. It can be understood that the wiping device 10 is a small and lightweight device.
In addition, it is preferable that the ratio L2/W2 between the length L2 and the width W2 of the arm portion 21 is usually a value within the range of 1.25 to 15.

Here, when the arm portion 21 is elongated, the length L1 (see FIG. 3) of the arm portion 21 is preferably twice the width W2 of the arm portion 21 or more, and more preferably 3 times or more. good.
The reason for this is that if L1/W2 is set to such a ratio, the wiping head 13 is arranged so as to be separated from the roll mounting portion 19 by the dimension L1.
Moreover, the influence of the width of the arm portion 21 itself can be reduced, and the risk that the roll mounting portion 19 comes into contact with the wiping target 25 can be reduced as compared with the conventional case.
That is, even if the wiping target 25 has a small size or a complicated shape, the desired wiping operation can be performed without the roll mounting portion 19 coming into contact with the wiping target 25.

The width and length of the arm portion 21 and the ratio of the width to the length can be arbitrarily designed according to the application of the wiping device.
In the case of this embodiment, the arm portion 21 has a width W2 (see FIG. 3) narrower than the width W1 (see FIG. 3) of the roll mounting portion 19 and is a long and linear frame.
The wiping head 13 is provided at the tip of the arm portion 21. The arm portion 21 is not limited to the linear shape and can be changed according to the design.
For example, the arm portion 21 may be an arm portion that is linearly extended from the roll mounting portion 19 and then bent, that is, an L-shaped arm portion. Anything is fine.

7. Wiping member The wiping member is a tape shape having a predetermined width (for example, 2 to 70 mm) and a predetermined thickness (for example, 0.1 to 20 mm), and is in the form of an unwinding roll to be wiped. It is sufficient that a predetermined contaminant is absorbed and wiped off when it is brought into contact with a predetermined portion of the object, and further, a configuration in the form of a take-up roll in a state where the contaminant is absorbed.
Therefore, the wiping member is typically a non-woven fabric made of a polyolefin resin (including an oriacrylic resin), a polyamide resin, a polyester resin, or the like as a raw material.
However, a tape-shaped wiping member made of polyurethane sponge, microfiber, or the like may be used depending on the application because it has good absorbability or wiping property for predetermined contaminants.

Further, in the case of non-woven fabrics, there are many types due to the difference in the manufacturing method.
For example, the melt blown method, in which the resin is melted and jetted from around the spinning nozzle, the fibers are thinned and accumulated into a sheet, and the continuous long fibers obtained by melting and spinning the raw resin are directly accumulated. Spunbonding method of forming fleece by heating, fleece mixed with low-melting-point heat-sealing fibers is thermocompression bonded between hot rolls. Alternatively, a thermal bond method of applying hot air to bond the fibers to each other may be used.
In addition, the fleece is sprayed with a binder solution and dried to bond the fibers in a bulky state by the chemical bond method. The fleece is repeatedly stabbed with a needle (needle) that moves up and down at a high speed, and a barb is engraved on the needle. Needle punching method to entangle fibers, entanglement water flow method to inject high-pressure water stream into a column in a fleece to entangle fibers, short fibers are formed in a certain direction by a machine called card or air flow called air lay Any method such as a dry method may be used.

In the case of a non-woven fabric, if it is excessively stretched by application of a slight force, it may be difficult to transfer it smoothly by a driving roll, while if it is not stretched at all, the absorption of a predetermined contaminant becomes excessive. It may decrease.

Therefore, as an example, in the thickness of 0.1 to 20 mm and the width of 2 to 70 mm, the elongation percentage of the non-woven fabric measured according to JIS L1913:2010 is set to a value within the range of 1 to 400%. Is preferable, the value within the range of 10 to 150% is more preferable, and the value within the range of 20 to 100% is further preferable.

Further, similarly as an example, it is preferable to set the breaking elongation of the nonwoven fabric measured in accordance with JIS L1913:2010 to a value within a range of 1 to 50 kN/m, and a value within a range of 2 to 30 kN/m. Is more preferable, and a value within the range of 5 to 20 kN/m is further preferable.

8. Wiping Head The wiping head 13 is a member for bringing the wiping member 23 into contact with a predetermined portion of the object to be wiped 25 to wipe off a predetermined contaminant. The wiping head 13 is rotatably supported by the main body of the wiping device 10. In this embodiment, the wiping head 13 is provided at the tip of the arm portion 21.
In the case of the wiping device 10 of the first embodiment, the wiping head 13 includes a bearing member 13a and a columnar member 13b connected to the bearing member 13a.
The columnar member 13b is a columnar member. The wiping member 23 is suspended on the columnar member 13b.
Therefore, the contact surface of the wiping member 23 with respect to the wiping member 24 is a curved surface, and the contact of the wiping head 13 with the wiping target 25 is in a line contact state.
Further, since the columnar member 13b is rotatable, when the take-up roll 17 operates, the wiping member 23 smoothly transfers the portion of the wiping head 13 to the wiping member 23.

In the wiping device 10 of this embodiment, the holding angle of the wiping member 23 in the wiping head 13 is 150 degrees or more, and more preferably 180 degrees or more.
Here, the holding angle is the angle α shown in FIG. That is, it is the spread angle of the portion where the wiping member 23 is in contact with the wiping head 13.
The state of the angle α in FIG. 5A is an example in which the holding angle exceeds 180 degrees.
When the holding angle is increased, the portions of the wiping member 23 other than the tip end portion of the wiping head are not arranged side by side along the work, but rather are distant vertically from the object to be wiped 25 to the roll mounting portion 19 side. become.
Therefore, the portion of the wiping member 23 other than the tip portion of the wiping head does not interfere with the wiping operation.
