Description

TECHNICAL FIELD The present invention relates to a technique for manufacturing a decorative part by attaching a decorative sheet to the surface of a long metal base material, and more particularly to a technique for automatically cleaning the surface of the base material as a pretreatment for attaching the decorative sheet. be. The outer surface of the metal substrate has, for example, a box-shaped cross section.

Conventionally, in the process of attaching a decorative sheet to the surface of a long metal base material, we searched for publications relating to the process of automatically cleaning the surface of the base material as a pretreatment for the process of applying the decorative sheet, but could not find any.

On the other hand, although it is not a manufacturing technique for decorative parts, there is a method described in Patent Document 1 as an invention relating to cleaning of a metal plate being transported. Patent Literature 1 describes that one or both of alkali cleaning and pickling are performed on a conveyed cold-rolled steel sheet.

JP 2006-348377 A

However, in the cleaning method as described in Patent Document 1, after the steel plate is immersed in the solution, it is necessary to perform a treatment such as draining and drying, so there is a problem that the equipment becomes large-scale. It is difficult to apply it as a cleaning as a pre-treatment just before sticking.

Further, even if the metal plate is manufactured by performing the cleaning method as described in Patent Document 1, when the metal plate is subsequently processed to manufacture a metal base material, cutting oil may be applied to the surface of the base material. Oil such as adheres. In addition, sebum or the like may adhere to the surface of the base material when it is transferred to equipment for attaching the decorative sheet to the base material. Furthermore, dust may adhere to the substrate surface when the substrate is moved or stored. If the decorative sheet is attached while cutting oil or the like is attached, it may cause an attachment failure.

For this reason, conventionally, just before attaching the decorative sheet to the surface of the metal base material, the surface of the received base material is cleaned by hand-wiping with a waste cloth to which acetone is added. Then, the washed base material is put into a decorative sheet applying device (wrapping machine) to apply the sheet.
However, manual cleaning has the problem that it takes time and effort.

The present invention has been made in view of the above points, and an object of the present invention is to automate the cleaning of the base material surface as a pretreatment for attaching a decorative sheet with a simple configuration.

In order to solve the problem, one aspect of the present invention provides a cosmetic product manufacturing apparatus for manufacturing a cosmetic component formed by attaching a decorative sheet to a surface of a long metal base material, wherein before attaching the decorative sheet and a cleaning device for cleaning the surface of the metallic base material, the cleaning device comprising: a conveying device for conveying the metallic base material; and a cleaning liquid supply device for supplying cleaning liquid to the sliding contact surface of the wiping tool.

Another aspect of the present invention is a surface treatment method for cleaning the surface of a long metal substrate, wherein a wiping tool supplied with a cleaning liquid is rubbed on the surface of the metal substrate being transported. The surface of the metal substrate is cleaned by bringing it into contact with the metal substrate, and the wiping tool comprises a rotating roller, and the axis of the rotating roller is tilted from a direction orthogonal to the conveying direction of the metal substrate. and suppressing axial rotation of the rotating roller.

ADVANTAGE OF THE INVENTION According to the aspect of this invention, it becomes possible to automatically wash the surface of the base material immediately before attaching the decorative sheet with a simple device configuration.

Next, embodiments based on the present invention will be described with reference to the drawings.
The present embodiment relates to a cosmetic product manufacturing apparatus for manufacturing cosmetic parts.
For example, as shown in FIG. 1, the decorative component 1 is configured by attaching a decorative sheet 3 to the surface of a long metallic substrate 2 .

(composition)
<Cosmetic part 1>
Although FIG. 1 illustrates the case where the outer surface of the base material 2 has a rectangular cross section (box shape), the shape of the base material 2 is not limited to this. The base material may be configured in other shapes, such as the base material being composed of a face plate and ribs provided on the back surface of the face plate. Also, the base material 2 is made of, for example, aluminum or an aluminum alloy.

1 exemplifies the case where the decorative sheet 3 is attached to the entire surface of the substrate 2; It may be attached only to a part of the surface of the material 2 .

<Cosmetics manufacturing equipment>
As shown in FIG. 2, the cosmetic product manufacturing apparatus of this embodiment is arranged in the order of a table 10, an input booth 20, a washing booth 30, and a wrapping machine 40 from the upstream side. Then, the base material 2 is subjected to each treatment while being continuously conveyed along the pass line P in the order of the table 10, the input booth 20, the cleaning booth 30, and the lapping machine 40. As shown in FIG.
In addition, the base material 2 is arranged and conveyed along the pass line P in the longitudinal direction.

<Table 10>
The table 10 is a table on which the substrates 2 are sequentially placed. For example, an operator sequentially places a plurality of substrates 2 placed on other tables onto the table 10. . This remounting work may be performed by a robot arm. Although there is a risk that fingerprints or the like may adhere to the base material 2 during this operation, there is no problem because the base material 2 is washed in the washing booth 30 immediately before the decorative sheet 3 is affixed.

The table 10 is composed of a table roller on which a plurality of rolls 10a are arranged along the pass line P (conveyance direction), and the base material 2 can be guided in the direction of the pass line P by the table roller. .

<Input booth 20>
A feed roller 22 is arranged to feed the substrate 2 conveyed from the washing booth 30 toward the washing booth 30 . The feed roller 22 has, for example, a roller that contacts the bottom surface of the base material 2, a roller that contacts the top surface of the base material 2, and a contact roller that contacts the side surface of the base material 2. It is possible to send it straight along the pass line P toward the washing booth 30. - 特許庁The feed roller 22 constitutes a conveying device.

<Washing Booth 30>
The cleaning booth 30 is composed of a small room surrounded by a transparent acrylic plate or the like, which is opened at an entrance and an exit for conveying the substrate.
An exhaust duct 37 is provided in the cleaning booth 30, and gas in the cleaning booth 30 is forcibly exhausted to the outside by an exhaust device (not shown). As a result, the cleaning liquid 34 is prevented from adhering to, or being sucked from, surrounding workers, devices, and the like.

Inside the cleaning booth 30 are a wiping tool that slides on at least the surface 2a of the substrate 2 on which the decorative sheet 3 is attached, and a cleaning liquid supply device 33 that supplies a cleaning liquid 34 to the sliding contact surface of the wiping tool. have

<wiping tool>
The wiping tool of this embodiment is composed of a rotating roller 32, as shown in FIG.
The rotating roller 32 has a shaft member 32b and a cylindrical roller body 32a arranged around the shaft member 32b.

The rotating roller 32 may be, for example, a general-purpose paint roller. In this case, procurement of the rotating roller 32 is easy. It is preferable that the peripheral surface of the rotating roller 32, which is the sliding contact surface, has a high water retention capacity for the cleaning liquid 34. As shown in FIG. For this reason, the material of the roller main body 32a constituting the peripheral surface of the rotating roller 32 is preferably a bristle material (raised synthetic resin, etc.) rather than rubber or sponge having low water retention.

As the material of the rotating roller 32, acrylic fiber, polyester fiber, or nylon fiber can be used, but polyester fiber, which has excellent strength, abrasion resistance, and durability, is preferable. As the structure of the rotating roller 32, high pile or woven fabric can be used, but woven fabric is preferable because it has excellent finish, low solvent scattering property, and is resistant to wear and tension.

In addition, the rotating roller 32 of this embodiment is a non-driven rotating roller 32 .
Moreover, it has the movable device 35 which moves the shaft member 32b.

The movable device 35 has an advance/retreat function that allows the rotating roller 32 to advance and retract toward the surface 2 a of the substrate 2 , and a turning function that rotates the shaft of the rotating roller 32 along the surface 2 a of the substrate 2 . have. As for the configuration of the movable device 35, a known drive mechanism may be adopted.

Then, according to the shape and cross-sectional dimensions of the base material 2 , the advancing/retreating function is driven so that the rotating roller 32 can be reliably brought into contact with the surface 2 a of the base material 2 . Also, the turning function enables adjustment of the direction of the axis of the rotating roller 32 with respect to the conveying direction. The movable device 35 constitutes a changing mechanism that changes the inclination of the axis of the rotating roller 32 with respect to the conveying direction of the base material 2 .
The movable device 35 is configured to be automatically driven by a command from the control unit or to be driven by a command from an operator.

Then, as shown by the solid line in FIG. 3 , the axis of the rotating roller 32 is arranged at an angle θ from the direction orthogonal to the conveying direction (pass line P) of the metal base material 2 . To suppress axial rotation of a rotating roller 32 accompanying transportation.

The angle θ is, for example, in the range of 30 degrees to 90 degrees. This angle θ may be set from an angle range in which the axial rotation of the roller body 32a of the rotating roller 32 is suppressed based on the width of the surface 2a of the base material 2 and the pressing force of the rotating roller 32 against the base material 2. .

By making the rotating roller 32 non-rotating, even if the rotating roller 32 is used, the wiping performance more than required can be exhibited.

However, periodically or irregularly, the rotating roller 32 is temporarily displaced in the direction in which the angle θ of the rotating roller 32 decreases, which is the position indicated by the dashed line in FIG. Temporary rotational displacement of 32a is preferred. Accordingly, local contamination and local deterioration of the rotating roller 32 can be suppressed by changing the wiping surface regularly or irregularly. For example, it is preferable to rotationally displace the rotating roller 32 at the seam between the substrates 2 being transported. In this case, it becomes difficult to transfer the contamination of the previous base material 2 to the next base material 2 .

Here, in the present embodiment, the inclination of the shaft of the rotating roller 32 is changed to temporarily rotate and displace the rotating roller 32, but the changing mechanism may not necessarily be provided.
For example, if a gap is provided between the substrates 2 that are continuously fed, even if the axis of the rotating roller 32 is tilted, the substrate 2 currently being washed is relatively rotated from the tail end. When the roller 32 leaves, the pressing force of the rotating roller 32 on the surface 2a of the base material 2 is released, and further, when the rotating roller 32 comes into contact with the leading end of the next base material 2, the conveyance of the base material 2 is interrupted. Accordingly, the roller main body 32a of the rotating roller 32 is automatically rotationally displaced.

Here, it is preferable to provide another rotating roller 50 after the rotating roller 32 for cleaning. Moreover, the structure which wipes the same surface 2a of the base material 2 with several rotating rollers 32 may be sufficient. Another rotating roller 50 has the effect of absorbing the cleaning liquid 34 in the event that the cleaning liquid 34 adheres excessively to the surface 2 a of the substrate 2 . Further, another rotating roller 50 is effective as a dirt check function of the cleaning rotating roller 32 during long-lot production. That is, if the cleaning by the cleaning rotating roller 32 becomes insufficient, dirt adheres to another rotating roller 50, and it is necessary to replace the cleaning rotating roller 32 or change the surface to be rotated and wiped. can be determined. This other rotating roller 50 is a preliminary roller and also has a role of a checker against contamination of the rotating roller 32 for cleaning. The inclination of the axis of the separate rotating roller 50 need not match the inclination of the axis of the cleaning rotating roller 32 .

<Cleaning liquid supply device 33>
As shown in FIG. 2, the cleaning liquid supply device 33 of this embodiment is configured to supply the cleaning liquid 34 to the sliding contact surface of the rotating roller 32 by adding the cleaning liquid 34 to the roller main body 32a of the rotating roller 32. ing.
In FIG. 2, reference numeral 33b denotes a tank containing the cleaning liquid 34, and reference numeral 33c denotes a pump for intermittently or continuously pumping the cleaning liquid 34 toward the nozzle 33a.

The cleaning liquid 34 may be an organic solvent such as acetone, methyl ethyl ketone, toluene, dichloromethane, ethyl acetate, methyl cellosolve, or a commercially available metal cleaning agent.

[Modification]
(1) A wiping tool other than the rotating roller 32 may be used. For example, as shown in FIG. 4, the wiping tool 36 may be a pad main body 36a whose sliding contact surface is made of a bristle material (raised synthetic resin or the like). Reference numeral 36b is a rigid body portion that supports the pad main body 36a.

(2) Further, the supply of the cleaning liquid 34 to the sliding contact surface is not limited to the case where the cleaning liquid 34 is directly supplied to the parts forming the sliding contact surface. For example, as shown in FIG. 4, the cleaning liquid 34 may be supplied to the sliding surface of the wiping tool by spraying the cleaning liquid 34 onto the surface 2a of the substrate 2 at the upstream position of the wiping tool.

<Lapping machine 40>
The substrate 2 conveyed by the feed rollers 22 of the input booth 20 is washed in the washing booth 30 and then continuously sent to the wrapping machine 40, where the surface 2a of the substrate 2 is decorated. A sheet 3 is applied.
That is, in the present embodiment, the surface 2a of the base material 2 is cleaned immediately before the decorative sheet 3 is attached to the surface 2a of the base material 2 .

The wrapping machine 40 has a configuration as shown in FIG. 5, for example.
A lapping machine 40 shown in FIG. 5 has guide rollers 41 for guiding the substrate 2 sent from the washing booth 30 and pinch rollers 43 for pressing and attaching the decorative sheet 3 to the substrate 2 . That is, as shown in FIG. 5, the adhesive 42 is continuously applied to the surface of the rewound decorative sheet 3, and the adhesive 42 is applied to the decorative sheet 3 after drying the adhesive 42 in a drying oven. , is continuously supplied toward the surface 2a of the base, and the decorative sheet 3 is continuously adhered to the base by the pinch rollers 43. As shown in FIG.

FIG. 5 illustrates a case where the decorative sheet 3 is attached to the upper surface and then folded at both widthwise positions by the pinch rollers 43 so that the decorative sheet 3 is continuously attached to the side surface of the base material 2 . ing.

(Other operations)
In this embodiment, the input substrate 2 is conveyed along the pass line P by the feed rollers 22 of the input booth 20, and the cleaning booth 30 just before the decorative sheet 3 is attached to the surface 2a of the substrate 2. Inside, the surface 2a of the base material 2 is automatically cleaned, and then the decorative sheet 3 is attached to the surface 2a of the base material 2. As shown in FIG.
As a result, it is possible to automatically clean the base material surface 2a immediately before the decorative sheet 3 is attached, with a simple device configuration.

Further, when the rotating roller 32 is used as the wiping tool, local contamination and local deterioration of the wiping tool can be suppressed by rotating and displacing the rotating roller 32 appropriately. As a result, it is possible to set a longer maintenance interval for the wiping tool.

Also, by performing the cleaning in the cleaning booth 30, the vapor of the cleaning liquid 34 is prevented from scattering, and the need to wear a protective mask is eliminated.
