Abstract
The subject of this invention is making it possible to apply | coat an application | coating material to this film in the state which the curl correction of the both side edge parts of a film is made, and to improve the application | coating quality of a film.
The film 1 unwound from the unwinding side film roll 2 is wound up by the winding-up film roll 3, and is conveyed so that the application | coating object area may be located on the adsorption table 10 by the application part 17. When the area | region to apply | coat is located on the adsorption table 10, the film 1 will stop and be loaded on the adsorption table 10, and tension will be added in the longitudinal direction, and looseness etc. will be removed. However, by this, curl is generated in both side portions of the area to be coated. Therefore, while the application target area is loaded on the suction table 10, the curl straightening bars 13 and 14 provided on both sides of the suction table 10 move to the curl portion of the application target area, and this portion of the suction table is moved. Curl correction is performed by pressing on the suction surface.
Description
BACKGROUND OF THE
Background Art Conventionally, as an example of a printing apparatus, an introduction portion for introducing a print medium while removing curls and aligning in the width direction, and is disposed adjacent to the introduction portion and disposed opposite to the print medium to convey the print medium by a belt. A print medium which is arranged opposite to a conveying unit, a print unit having a plurality of rows of line heads corresponding to the number of types of colors, and downstream of the conveying direction of the print medium in the print unit, The printing apparatus provided with the drying part which dries is known (for example, refer patent document 1).
In such a printing apparatus, curling is removed with a plurality of rollers in a sheet-like print medium (for example, a fabric stored in a roll shape or a box), and the centering in the conveying direction center and the grain correction of the cloth, Curling of both ends (both edges of the fabric) is performed.
In this case, tension is applied to the fabric by a plurality of rollers, and the curls of both edges of the fabric are also corrected. However, the direction of tension is large in the longitudinal direction of the fabric, and both sides of the fabric are perpendicular to the longitudinal direction of the fabric. The tension on the curl is slightly smaller.
In addition, this curl correction is performed in the carry-in part which is located in the front position rather than the place to print on this fabric, and in both the section to the print part after passing through this carry-in part, and in the print part, The tension for the correction of the curls will be close to that once opened.
In the film unwound and conveyed by the roll-to-roll system, there exists a site | part in which the semiconductor material is vapor-deposited on the surface, and the site | part in which it is not deposited, for this reason, the both side edge part of the width direction of a film is rounded (curled). . When the film unwound from the roll is adsorbed and held on the adsorption table for application of the amount of coating material, if the curls are present at both side edges in this manner, the film is less likely to be adsorbed flat on the adsorption table, resulting in curling or loosening. There is a problem that occurs. In this way, when curling or loosening occurs, the nozzle tip surface such as the inkjet for coating may contact the film, and the nozzle surface may be damaged.
SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem and to apply a coating material to the film in a state in which curls on both side portions of the film are fixed, and to improve the coating quality to the film, and To provide a way.
In order to achieve the above object, the present invention is a liquid coating material on the upstream guide roll for unwinding and conveying a roll-shaped film, an adsorption table for adsorbing and holding the unwinded film, and a film adsorbed and held in the adsorption table. An inkjet coating device comprising a coating head for applying a coating material and a downstream guide roll for conveying a film coated with a coating material and winding in a roll shape, and adsorbing both side edge portions in an application target area mounted on an adsorption surface of an absorption table of the film. A curl correction bar is provided which is pressed against the suction surface of the table and widens to the side of the suction table, and the curl portions generated at both side portions in the area to be coated with the film are corrected by the curl correction bars, so that the entire application area is flat. It is characterized by maintaining the adsorption uniformly on the adsorption surface of the adsorption table.
In addition, the adsorption surface of the adsorption table is divided into the central region and the peripheral region on both sides of the central region with respect to the direction perpendicular to the conveying direction of the film, and the operation of the vacuum suction hole in the central region and the vacuum suction hole in the peripheral region. And a control unit for controlling the operation of the control unit. The control unit controls the vacuum adsorption holes in the central region along with the loading of the application target area of the film onto the adsorption table to face the central region of the application target area. The vacuum suction holes in the peripheral area together with the curl correction of both side edges in the application target area of the film loaded on the adsorption table by the curl correction bar and operating the vacuum suction holes in the application target area to face the peripheral area of the application target area. It is characterized by holding the vacuum suction area.
Moreover, it is characterized by including the means for detecting the floating from the adsorption surface of the adsorption table of the film vacuum-adsorbed to the adsorption table.
In addition, a means for adjusting the air pressure of the lifting cylinder for driving the lifting operation of the curl correction bar for adjusting the force of pushing up and extending both side portions of the area to be coated with the film to both side sides of the suction table by the curl correction bar. It is characterized by one.
In order to achieve the said objective, this invention unwinds and conveys the film wound up in roll shape with the guide roll of an upstream, and the area | region to apply the uncoiled film is mounted in the adsorption surface of the adsorption table, Liquid coating material is apply | coated to the application | coating target area of a film, The film to which the coating material was apply | coated is an inkjet coating method conveyed by the downstream guide roll, and wound up in roll shape, The application target of the film mounted on the adsorption surface of the adsorption table Both sides of the area are pressed against the adsorption surface by a curl straightening bar to be widened to the side of the adsorption table to be adsorbed and held on the adsorption surface.
According to the present invention, when fixing and positioning the film to be applied to the adsorption table, both sides of the film are pressed to the adsorption table by the curl correction bar and adsorbed, so that curls occurring on both sides of the film are corrected. The film is fixed to the adsorption table flatly, and in this state, the coating material is applied to the film, so that the coating quality of the film is improved.
