Abstract

<P>PROBLEM TO BE SOLVED: To solve such a problem of the conventional apparatus for applying and/or packing paint to/into a substrate that continuous work is hardly done and the thickness of a coating film is uneven. <P>SOLUTION: The substrate is conveyed horizontally or vertically. When the substrate is conveyed horizontally, the substrate is erected and then hung by a hanger. When the substrate is conveyed vertically, the substrate as it is is hung by the hanger. The hung substrate is lowered and then raised. Paint is applied to the substrate or packed into holes on the substrate by using a rotary coating roll while raising the substrate. The surplus paint on the substrate is scraped off by a squeegee to smooth the paint-applied/packed surface of the substrate. The contact surface of the squeegee is made wide so that the paint on the substrate can be smoothed uniformly. <P>COPYRIGHT: (C)2006,JPO&NCIPI

(2) Since the substrate is difficult to bend at the time of filling the coating material, the coating material can be applied to a uniform thickness and filled into the hole reliably, and the coating roll is hardly damaged.
(3) Since the substrate is suspended and transported, it can be taken over to another process while suspended, and the direction of the substrate can be changed more easily than when it is transported by a conveyor, making it easier to perform various operations continuously. , Work efficiency is improved.
(4) Since the substrate is suspended and transported, it is not necessary to install a transport conveyor, and work in the air can be performed. Therefore, the work and the installation place of the apparatus are reduced, and the space can be saved.

For this reason, a transport body such as a conveyor for transporting the substrate is not necessary, and coating and filling can be performed with a simple system.
(2) Since the rotary coating roll and the squeegee can reciprocate in the direction sandwiching the substrate and the direction away from the substrate, it is easy to adjust the position where the substrate passes between the rotary coating roll and between the squeegees, The substrate does not bend too much and the substrate is not curved. In addition, since the two pairs of spin coating rolls and the squeegee can be uniformly applied to the front and back surfaces of the substrate, a coating film having a uniform thickness can be formed on both surfaces of the substrate. In addition, when the substrate is fed between the rotation coating rolls, the end of the substrate does not hit the rotation coating roll and the rotation coating roll is not damaged, so that a coating film having a uniform thickness can be formed on the substrate. it can.

(6) The paint application or / and filling device for the substrate according to claim 9 is such that the transport body can transport the substrate in a vertical orientation with its front and back sides directed sideways. Since the substrate that has been transported by the transport body can be suspended as it is by a lifting tool, there is no need for a stand-up device in the case of a transport body that transports the substrate sideways, which simplifies the configuration of the device and reduces its size. There is also an effect that it is possible.
(7) According to the tenth aspect of the present invention, the apparatus for applying and / or filling the substrate with the coating material has the contact surface of the squeegee with the substrate having a flat surface.

The coating material can be applied to the upper end of the substrate with a rotary application roll. When the substrate is separated from the lifting tool, the substrate cannot be lifted by the lifting tool. However, since the substrate can be pushed up by the rotation of the rotary application roll, the upper part of the substrate is not transferred to the upper side of the rotary application roll.

In this way, as shown in FIG. 1, the step of correcting the substrate 1 in the vertical direction, or the operation step of rotating the lifting tool 4 by 90 ° in the horizontal direction after the vertical substrate is held and suspended by the lifting tool 4. Is unnecessary, and the work process can be omitted. When the substrate 1 is transported in the vertical direction, support members 30 for preventing the substrate 1 from falling down are disposed on both sides of the substrate 1. In this case, the support member 30 can be laid down. If the support member 30 is laid down, the support member 30 can be supported even if the arm 1 is extended forward by suspending the substrate 1 transported by the transport body 2 with the hanger 4. Therefore, the arm portion 14 can be extended forward and the substrate 1 can be moved (conveyed) to the next process. In this case, the hanger 4 is arranged on the front side of the carrier as shown in FIG. 5, the substrate 1 conveyed by the carrier 2 is hung by the hanger 4 as it is, and the arm portion 14 is extended forward. The substrate 1 can be transported in a direction perpendicular to the transport body 2.

(Embodiment 4)
As shown in FIG. 6, the transport body 2 in the present invention is capable of transporting the substrate 1 in a horizontal direction in which the front and back surfaces are up and down, and transports the side of the hanger transport body 5. Also good. In this case, the transfer body 2 is provided with a standing device (not shown) so that the transferred substrate 1 can stand upright. In this way, there is no need for a work process for rotating the suspension tool 90 by 90 ° in the horizontal direction after the vertically oriented substrate as shown in FIG. Can do. Further, in this case, the lifting tool 4 is disposed on the side of the transport body 2 as shown in FIG. 6, and the substrate 1 that is transported by the transport body 2 and is erected in the vertical direction by the standing device 4. And the arm part 14 is extended forward so that the substrate 1 can be transported in a direction orthogonal to the transport body 2.

(Embodiment 5)
In any of the illustrated embodiments, the suspended substrate is lowered and then lifted, and the paint is applied to the substrate or scraped off during the lifting. In the present invention, the suspended substrate is lowered. In the meantime, paint can be applied to the substrate or scraped off. In that case, place the rotary coating roll above the squeegee, apply the paint to the substrate with the rotary coating roll while the substrate is descending, and if the substrate further descends, the squeegee will scrape off or level the substrate. Or If the board is flexible, if you hang the top edge of the board and hold the bottom edge of the board with a clamp to give tension to the board (while applying tension), lowering the board will deform the flexible board. It becomes difficult to move down, the descent becomes smooth, and the application of the paint to the substrate and the leveling and scraping of the paint are likely to be uniform. When the operations such as coating, scraping and leveling are finished, the substrate is lifted. At this time, it goes without saying that the rotary coating roll and the squeegee are separated from the substrate so that the substrate can be pulled up smoothly.

(Embodiment 6)
In any of the illustrated embodiments, the substrate is transported by the transport body, and the transported substrate is suspended and held by a lifting tool. Of course, it is also possible to attach it directly to the suspension.
