Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a surface processing machine for polishing the surface of a product or forming a straight streak on the surface.

[Prior art and its problems]

For household appliances, a decorative plate made of aluminum and the like may be used.However, when linear streaks are formed on such a decorative plate made of aluminum, it has a luster like stainless steel. A so-called hairline process has been performed in which an endless paper band is run, and the paper band is pressed against a product to form lines on the product surface.

By the way, if the width of the paper band is narrower than the width of the product, lines are formed only in a part of the product. Therefore, the width of the paper band is generally formed wider than the width of the product. However, if the width of the paper band is wider than that of the product, streaks will be formed only in a part of the width direction of the paper band, and only the part used for the paper band will be worn away. Then, there was a problem that the life of the paper band becomes short.

[Purpose of device]

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a surface processing machine in which the entire area in the width direction of a surface processed belt such as a paper band is used almost uniformly.

[Outline of the Invention] In order to achieve the above-mentioned object, the present invention provides a surface processing band that moves in the horizontal direction to process the upper surface of a product, and a moving direction of the surface processing band while pressing the upper surface of the surface processing band. It is characterized in that a pressing pad that reciprocates in one direction and a product mounting table that vibrates in a horizontal direction orthogonal to the moving direction of the surface processing band only when the pressing pad moves forward are arranged.

According to the present invention having such a configuration, the pressing pad is moved horizontally in the horizontal direction and the pressing pad is reciprocated in the traveling direction of the surface processing band so as to be pressed against the product. By vibrating the mounting table in the direction orthogonal to the movement direction of the surface processing band, it is possible to perform a predetermined surface processing on the product using almost the entire width direction of the surface processing band and meander on the surface of the product. It is possible to form a linear streak, and then to easily form a linear streak.

Has been done. Then, the vehicle is driven through the rotation of one pulley 32 driven by a motor (not shown).

The linear motor 5 and the motor for traveling the paper band 10 and the cylinder devices 14, 18 and 26 are controlled by a sequencer (not shown) and driven. Of these, the stroke of the first cylinder device 14 is controlled by the sensors S1 and S2 attached to both ends of the cylinder 15, and the product A is vibrated in the width direction of the paper band 10. In order to let

First, the linear motor 5 is driven to adjust the height of the movable bed 7 so as to match the thickness of the product A. Then, a product having a width narrower than the width of the paper band 10 is placed on the product placing table 17 mounted on the movable plate 12, and a foot switch (not shown) is pressed to drive the first cylinder device 14 by the sequencer. Then, the piston rod 16 in which the sensor S1 is turned on in FIG. 4 is pulled backward as shown by the arrow A, and the movable plate 12 supporting the product mounting table 17 is moved to the guide rail 9 on the movable bed 7. , Rearward along 9
The upper product A is positioned below the paper band 10 and the piston rod 28. The first cylinder device 14 is
When the product A on the product mounting table 17 is positioned below the paper band 10 and the piston rod 28, it is stopped by the sensor S2. Then, the third cylinder device 26 is driven by the sequencer to turn on the sensor S4, and the cylinder 27 is turned on by the arrow B.
As shown by, the piston rod 28 is turned on and the sensor S5 is turned on.
Until the end of the product A in the traveling direction of the paper strap 10 is pressed through the paper strap 10. After that, the sequencer drives the first cylinder device 14 so that the sensor S3 and the sensor S2 are alternately turned on to move the movable plate 12 together with the product mounting table 17 and the product A as shown by arrows C and D. While vibrating in the width direction, the second cylinder device 18 is driven until the sensor S8 is turned on as indicated by the arrow E, and the pressure pad that is in pressure contact with the product A on the product mounting table 17 via the paper band 10 is pressed. 29 is moved to the left in FIG. 1 as a forward movement, and the paper band 10 is driven by driving a motor (not shown). Then, the product A on the product mounting table 17
A hairline process is performed on the surface of the paper sheet to form a serpentine line using the entire area of the paper band 10 in the width direction.

Then, when the sensor S8 of the second cylinder device 18 is turned on,
The pressing pad 29 is moved rightward in FIG. 1 as a forward movement until the sensor S6 is turned on as shown by an arrow F, and the surface of the product A on the product mounting table 17 is moved by the running paper band 10. The hairline is processed again. When the pressing pad 29 is returned, the first cylinder device 14 is not driven by the sequencer, and the hairline processing for forming the linear streaks on the product A is performed. Then, when the sensor S6 is turned on, first, the third cylinder device 26 is driven until the sensor S4 is turned on as shown by an arrow G to separate the pressing pad 29 upward, and then the first cylinder device 26 is activated.
14 is driven until the sensor S1 is turned on as indicated by an arrow H, the processed product A is removed from the product mounting table 17, and the next product A is mounted on the product mounting table 17.

According to such an embodiment, since the product A is vibrated in the width direction of the paper band 10 by the first cylinder device 14 on the outward path of the pressing pad 29, the hairline processing is performed.
The entire width direction of 10 can be subjected to hairline processing, and the paper band 10 can be used evenly in the width direction to prolong the life of the paper band 10. Further, without using a large pad that covers the entire area of the product A at a time, a small pressing pad 29 is moved by the second cylinder device 18 and is partially pressed against the surface of the product A via the paper band 10. Since the hairline processing is performed in this manner, the frictional resistance between the paper band 10 and the pressing pad 29 is kept small, and the hairline processing can be stably performed without stopping the paper band 10 by the frictional resistance. Therefore, hairline processing can be reliably performed even if the product A becomes large. Furthermore, in the outward path of the pressing pad 29, since the lines are formed in a meandering shape in advance and the lines are formed in a straight line, compared with the case where lines are formed on the surface of the product A in which no lines are formed at all. It is easy to form straight lines.

The surface processing of the product A is not limited to the paper band 10, and various processing can be applied as long as it is a band-shaped material.

[Effect of device]

As described above, according to the present invention, since the surface processing is performed while vibrating the product in the width direction of the surface processing band in the outward path of the pressing pad, the entire width direction of the surface processing band can be used for the surface processing. By using the surface-treated zone uniformly in the width direction, the life of the surface-treated zone can be extended. Also, without using a large pad that covers the entire area of the product at once, the surface is processed by partially pressing the surface of the product through the surface processing band while reciprocating a small pressure pad. The friction resistance between the processing zone and the pressing pad is kept small, and the surface processing zone can be stably processed without being stopped by the friction resistance. Therefore, even if the size of the product is increased, the surface processing can be reliably performed.

In addition, since the lines are formed in a meandering shape on the outward path in advance and the lines are formed linearly on the return path, a straight line is formed as compared with forming a line on the surface of the product in which no lines are formed at all. It is possible to obtain a practical effect that it is easy to form streaks.
