Abstract

<P>PROBLEM TO BE SOLVED: To improve the coating efficiency of material to a filmy body by the conventional manual work further by automatically coating with a machine. <P>SOLUTION: The filmy body 3 is fed from a feeding device 1 and taken up to a take-up devise 2. In midway, a material 15 is coated with the squeegee 14 of a squeezing device 13 and then dried under heat in a reflowing device 4. The coating of the material 15 is performed through the rotation of a screen mask 5 supported under the state being wound cylindrically about a mask support 6 in synchronous with the running speed of the filmy body 3 and through the sliding contact of the squeegee 14 of the squeezing device 13 assembled within the screen mask 5 with the inner surface of the screen mask 5 during its rotation so as to push out the material 15 downwards. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a screen printing apparatus, and more specifically, a screen mask in a state of being wound in a cylindrical shape is rotated at a predetermined speed, incorporated into the inside, and a material is extruded by a squeegee disposed at a predetermined position, thereby forming a film-like shape. The present invention relates to a screen printing apparatus characterized in that a material is applied to the surface of a body.

  Conventionally, when a predetermined material is applied to the entire surface of a long film-like body, it has been manually performed using a brush or a spray.

  However, there is a problem in that it takes too much time and time when it is performed manually using brushes or sprays. Moreover, since it is too thin if it is applied once, it has to be repeatedly applied several times, and the work efficiency is poor.

  The present invention has been made in view of the above points, and is a screen printing apparatus capable of automatically and efficiently performing this by a machine when a predetermined material is applied to a long film-like body. Is intended to provide.

  Thus, the gist of the present invention is a screen printing apparatus that applies a predetermined material to a long film-like body that is fed from a supply device and wound up by a winding device. A screen mask in a state of being cylindrically wound around a mask support body which is made of an annular body of the same size and is rotatably supported in a vertical direction by a support roller disposed diagonally on the outer periphery of each annular body The squeegee device and the printing material supply device are incorporated in the screen mask, and the squeegee of the squeegee device is disposed at a position facing the base roll disposed on the lower surface of the film-like body, and the screen mask is placed in the film-like body. The screen printing apparatus is characterized in that it can be rotated along the moving direction of the film and in accordance with the moving speed of the film.

  Moreover, in the said structure, you may enable it to move a position of a stand roll suitably in the moving direction of a film-like body, and the direction which contacts / separates to a film-like body. In this case, the clearance between the squeegee and the film-like body can be adjusted, the thickness of the film-like body can be accommodated, and the amount of material to be applied can be adjusted It is.

  In the above configuration, a cleaner unit for wiping off the dirt on the screen mask may be disposed at an appropriate position in the rotation direction of the screen mask. In such a case, it is possible to save time and effort for frequently cleaning the screen mask by stopping the operation of the entire apparatus.

  The present invention is configured as described above, and a long film-like body fed from a supply device and taken up by a winding device is placed inside a screen mask that rotates in accordance with the moving speed of the film-like body. A material is extruded by a squeegee and printed on the film-like body. Since the coating is automatically performed by the machine as described above, it does not require much labor and time as in the case of the conventional manual operation. In addition, since a necessary and sufficient amount of the material is applied at a time, there is no need to perform repeated coating as in the prior art, and the efficiency can be greatly improved.

  Further, when the position of the pedestal roll can be appropriately moved in the moving direction of the film-like body and in the direction of contacting and separating from the film-like body, the clearance between the squeegee and the film-like body is adjusted. In addition to being able to cope with the thickness of the film-like body, the amount of the material to be applied can be adjusted.

  In addition, when a cleaner unit that wipes off the dirt on the screen mask is installed at an appropriate position in the direction of rotation of the screen mask, the operation of the entire apparatus is stopped and the screen mask is frequently cleaned. It is possible to save time and waste.

  In the best mode for carrying out the present invention, a screen mask that rotates from a supply device and rotates in accordance with the moving speed of the film-like body is taken up by a take-up device. The material is extruded inside by a squeegee and printed on a film-like body, which does not require much labor and time as in the case of the conventional manual work, and also eliminates the need for overcoating and greatly improves efficiency. It is something that can be done.

  FIG. 1 is an explanatory diagram of Embodiment 1 of the present invention, and FIG. 2 is a longitudinal sectional view of a main part.

  In the figure, 1 is a supply device, and 2 is a winding device. Reference numeral 3 denotes a long film-like body that is fed from the supply device 1 and wound up by the winding device 2. Reference numeral 4 denotes a reflow apparatus for heating the printed film and drying the applied material.

  Reference numeral 5 denotes a screen mask. In this embodiment, the screen mask 5 is made of a knitted mesh made of stainless steel in order to apply the material to the entire surface of the film-like body. Further, the screen mask 5 is supported in a state of being wound in a cylindrical shape on a mask support described later.

  Reference numeral 6 denotes a mask support, which is composed of a pair of parallel annular bodies 6A, 6A that are parallel to each other, and are disposed on diagonal lines on the outer circumferences of the annular bodies 6A, 6A. 9, the screen mask 5 is fixed to the step portions 6a and 6a formed inside the annular bodies 6A and 6A. Further, annular gears 10 and 10 are fixed to the outside of the annular bodies 6A and 6A, and the gears 10 and 10 are engaged with gears 11 and 11 provided on the outer periphery of the support roller 7, and the gears 11 and 11 is meshed with gears 12 and 12 connected to a drive source such as a motor.

  Reference numeral 13 denotes a squeegee device incorporated in a screen mask 5 supported in a state of being wound around the mask support 6 in a cylindrical shape. The squeegee 14 is in sliding contact with the inner surface of the screen mask 5 at a position directly below the figure. Like that. Reference numeral 15 denotes a material supplied by a printing material supply device 16 incorporated in the screen mask 5.

  Reference numeral 17 denotes a pedestal roll rotatably supported on a support pedestal 19 with a support shaft 18, and is disposed at a position facing the squeegee 14 of the squeegee device 13 on the lower surface of the film-like body 3. Further, the pedestal roll 17 can be appropriately moved in the moving direction of the film-like body 3 and in the direction of coming into contact with and away from the film-like body 3 as indicated by an arrow in the figure.

  Reference numerals 20 and 20 denote cleaner units disposed at appropriate positions in the rotational direction of the screen mask 5, which wipe away dirt on the screen mask 5.

Next, the operation of the first embodiment will be described.
The film-like body 3 is delivered from the supply device 1 and taken up by the take-up device 2. In the middle of the film-like body 3, a material 15 is applied by a squeegee 14 and is heated and dried by a reflow device 4. In addition, the material 15 is applied by rotating the screen mask 5 in accordance with the moving speed of the film-like body 3, and at this time, the squeegee 14 of the squeegee device 13 incorporated therein slides on the inner surface of the screen mask 5. , By extruding the material 15 downward.
