Description

  The present invention relates to a laminating apparatus, and more particularly to an apparatus that performs hot laminating.

  Laminating is a process in which a plastic thin film (laminate film) is adhered to the surface of the object to be processed, and is bonded to the surface of the object to be processed. Further, there is a cold laminating process in which a laminating film coated with a sticky adhesive is crimped to the surface of an object to be processed at room temperature.

  Cold laminating has the advantage that the equipment is simple and low-cost because it does not need to be heated unlike hot laminating, and the processed object is flexible, so there is a release paper on the back. By sticking a double-sided adhesive film with a sticky adhesive, there is an advantage in creating a sticker to be attached to a curved surface.

  In the hot laminating process, the heat-sensitive adhesive resin is melted by heating and is cured after the resin adheres to the object to be processed, so that the object to be processed has elasticity after being laminated, and the object to be processed can be effectively protected. There is an advantage of each, and it is used properly by making use of each advantage.

  A proposal of an apparatus capable of performing both the hot laminating process and the cold laminating process has been made as Japanese Patent Application Laid-Open No. 2001-277357, and various apparatuses dedicated to hot laminating process and cold laminating process are also known.

JP 2001-277357 A

  The laminating apparatus disclosed in Japanese Patent Application Laid-Open No. 2001-277357 is used for cold laminating, but can also be used for hot laminating as necessary, and has a feature that it can be used for both cold and hot. ing. However, since the original is sandwiched between the heater provided in the hot laminating unit used for hot laminating and the hot laminating film of the specified standard, the original to be laminated is the size. Small ones are targeted.

  In a laminating apparatus dedicated to hot laminating, as shown in FIG. 4, the laminate film 6 for the front surface and the laminate film 7 for the back surface use roll-wrapped films, and a heater is installed inside. A type is known in which an original is sandwiched between laminate films while the surface is heated to a predetermined temperature.

  This type of laminating device that uses roll-shaped laminating film is used by laminating processors to perform dozens of laminating processes even on single-cut documents, and after processing, the four corners of the document are cut with a knife, etc. It is cut and finished with.

  The laminated film is coated with a heat-sensitive adhesive resin, and is wound around a heated roller, so that the heat-sensitive adhesive resin melts and sticks to a document or the like to be processed. The temperature is about 120 ° C., and if the temperature is higher than that, the heat-sensitive adhesive resin will be burnt and will not stick to the document. Therefore, the surface temperature of the roller to be heated is controlled to a predetermined temperature. As shown in FIG. 1, the lower guide roller 5 is used for the lower roller 3 (hereinafter referred to as “lower laminating roller 3”). Is placed at a position away from the lower laminate roller 3 because the laminate film is not sufficiently wound around the lower laminate roller 3. This is because when the laminate film is set on the lower laminate roller 3 heated to about 100 ° C., the operator must work by inserting his hand from the lower part of the apparatus. This is because if there is a certain distance between the roller 5 and the lower laminating roller, there is a risk that the operator may touch the lower laminating roller 3 and burn his hands or fingers.

  The upper guide roller 4 installed on the upper right side of the upper upper laminating roller 2 in FIG. 1 can be operated while the operator can see it from the upper side, so that it is close to the temperature not affected by the temperature of the heated upper laminating roller. Is installed.

  When laminating, the heat-sensitive adhesive resin is processed while controlling the surface temperature of the upper and lower laminating rollers at a temperature at which the heat-sensitive adhesive resin does not burn. However, since the amount of laminating film wound around the lower laminating roller 3 is small, It takes a little time for the laminate film to melt the heat-sensitive adhesive resin. Therefore, there has been a problem that stable laminating cannot be performed unless the rotation speed of the upper and lower laminating rollers for laminating is set to a low rotation. If the surface temperature of the laminating roller is kept high because the amount of winding is small, there arises a problem that the heat-sensitive adhesive resin of the laminating film is burnt. Therefore, an improvement for stably laminating was desired.

  In order to solve the above-mentioned problems, claim 1 of the present invention is a hot laminating apparatus that performs hot laminating using a laminate film wound in a roll shape, and heats the surface temperature to a temperature required for laminating. An upper laminating roller, a lower laminating roller, and an upper guide member and a lower guide member for winding a laminating film around the upper laminating roller and the lower laminating roller, respectively. At least one of them is moved to a position away from the upper or lower laminating roller for setting the laminating film and widened with the upper or lower laminating roller, and the upper or lower laminating roller for laminating. Move to a position close to the laminate fill And a hot press device, wherein the positionable into a position to increase the amount of winding up or down laminate rollers. At the time of laminating, since the laminating film is wound in a large number, it is possible to perform laminating at a higher speed than before.

  According to the present invention, at least one of the upper guide member and the lower guide member is moved to a position away from the upper or lower laminating roller to set the laminate film, and a position where the interval between the upper or lower laminating roller is widened, It can be moved to a position close to the upper or lower laminating roller for laminating, and can be positioned at a position where the amount of the laminated film wound around the upper or lower laminating roller is increased. The problem in doing so can be solved and stable laminating can be performed. The guide member only needs to be able to move the laminate film smoothly, and various forms such as a non-rotating bar member and a rotating roller can be adopted.

  According to a second aspect of the present invention, the upper guide member or the lower guide member is provided on a cam plate rotatably provided on the frame of the main body, and a lever provided on an arm member that contacts the cam plate is rotated. The position of the arm member in contact with the cam plate is changed, and as a result, the rotation position of the cam plate is changed to position the upper guide member or the lower guide member. Item 1 is a hot laminating apparatus.

  According to the present invention, the upper guide member or the lower guide member can be rotated by the lever. The lever may be manually rotated by the operator, or an appropriate driving source such as an air cylinder is connected to the lever to automatically position the upper guide member or the lower guide member. You can also.

In the hot laminator, the position of the guide roller that wraps the laminated film around the heated laminating roller for laminating can be changed between setting the laminating film and laminating, so it is heated. Laminating film can be set without burning your hands or fingers with the laminating roller, and the laminating film can be heated sufficiently because the laminating film is wound around the laminating roller at the time of laminating. It can be laminated more stably than the laminating apparatus. It is also possible to set the speed faster than the conventional laminating apparatus.

  The embodiment of the present invention will be described. As shown in FIGS. 1 to 3, the hot laminating apparatus 1 according to the present invention includes an upper laminating roller 2 and a lower laminating roller 3 as a driving source (not shown) such as a motor. It is installed so that it can rotate freely. The upper laminating roller 2 and the lower laminating roller 3 have a structure in which a cavity is provided inside the roller, and a glass tube heater (not shown) is inserted therein and heated from the center of the roller. By measuring the surface temperature of the roller with a thermocouple (not shown) or the like, the temperature of the upper and lower laminating rollers can be controlled to a predetermined temperature.

  1 has a structure in which a surface laminate film 6 can be installed. The laminate film 6 a passes under the upper guide roller 4 and is wound around the upper laminate roller 2. The back surface laminate film 7 has a structure that can be installed in the lower left of FIG. 1, and the laminate film 7 a passes under the lower guide roller 5 and is wound around the lower laminate roller 3.

  The table 8 is a guide for facilitating the passage of the document A, which is an object to be processed, between the upper laminating roller 2 and the lower laminating roller 3. The original A, which is heated and laminated by the upper laminating roller 2 and the lower laminating roller 3, passes between the upper pulling roller 9 and the lower pulling roller 10 while being sandwiched between the laminating films, and goes to the outside of the laminating apparatus 1. Discharged.

  Here, as shown in FIG. 2, the lower guide roller 5 is rotatably supported on the cam plate 11 through a hole 18 whose end of the shaft 5a is opened in the frame side plate 17. The cam plates 11 are provided on both the left and right sides of the laminating apparatus 1 and are rotatably attached to the frame side plate 17 with the support shaft 11a as a rotation shaft. Further, on the side shown in FIG. 2, the cam plate 11 has a structure in which one end of the tension spring 12 is attached and is always urged to the left front side in FIG. The other end of the tension spring 12 is fixed to the frame side plate 17.

  As shown in FIG. 2, a bearing 14 that contacts the cam plate 11 is provided on the arm 15, and a lever 13 is attached to the arm 15 via an arm shaft 16. By rotating the lever 13, the arm 15 is rotated, and the position where the bearing 14 contacts the cam plate 11 is changed.

  That is, the state of FIG. 2 is a state in which the bearing 14 provided on the arm 15 is in contact with the first guide portion 11b of the cam plate 11, and the position of the guide roller 5 is the position of FIG. When the lever 13 is rotated and tilted as shown in FIG. 1, the bearing 14 moves while being in contact with the cam plate 11, and as a result, the cam plate 11 is rotated while being in contact with the bearing 14. Of course, the cam plate on the side opposite to that shown in FIG. 2 is also connected by the support shaft 11a, so that it rotates in the same manner as the cam plate 11 on the side shown in FIG. The bearing 14 comes into contact with the second guide portion 11c of the cam plate 11, the cam plate 11 stops rotating in the state shown in FIG. 1, and the lower guide roller 5 is positioned at the position shown in FIG. Thus, the position of the lower guide roller 5 can be changed by rotating the lever 13 as described above.

  Next, a procedure when using the laminating apparatus 1 will be described. First, the main power is turned on to heat the upper and lower laminating rollers to a usable temperature. Usually, the set temperature is reached in about 10 to 30 minutes. And the upper laminating roller 2 is raised a little using the lever (not shown) for moving the upper laminating roller 2 up and down. Although not described in detail because of a well-known structure, when the lever is actuated, it is raised about 10 mm. As a result, a gap of about 10 mm is formed between the upper laminating roller 2 and the lower laminating roller 3.

  The front end of the laminating film 6a is pulled out from the laminating film 6 for the surface set in the laminating apparatus 1, passed through the lower side of the upper guide roller 4, and wound around the upper laminating roller 2 with the heat-sensitive adhesive resin surface side outside, and the upper laminating roller 2 and the lower laminating roller 3 are passed out to the outside of the laminating apparatus 1.

  With the lever 13 in the state shown in FIG. 1, the lower guide roller 5 is positioned so as to be away from the lower laminating roller 3. The leading end of the laminating film 7a is pulled out from the laminating film 7 for the back surface set in the laminating apparatus 1, and the heat-sensitive adhesive resin surface side is set to the outside through the leading end of the laminating film 7a from the lower side of the lower guide roller 5 to the lower laminating roller 3 side. Then, it is wound around the lower laminating roller 3 and passed through the space between the upper laminating roller 2 and the lower laminating roller 3 to the outside of the laminating apparatus 1.

  When the laminating films 6a and 7a are set, the upper laminating roller 2 is lowered and an operation switch (not shown) is pushed to slightly rotate the upper laminating roller 2 and the lower laminating roller 3. This state is shown in FIG.

  Then, the lever 13 is rotated to the state shown in FIG. 3, the position of the lower guide roller 5 is moved closer to the lower laminating roller 3, and the winding amount of the laminating film 7a around the lower laminating roller is increased.

  In this state, if an operation switch (not shown) for rotating the upper laminating roller 2 and the lower laminating roller 3 is pressed and the original A to be laminated is put straight in the film conveying direction, laminating can be performed. The surface temperature of the laminating roller is set to be controlled at about 100 ° C.

  In the above description, the laminate film 6 for the front surface and the laminate film 7 for the back surface use rolls wound so that the heat-sensitive adhesive resin surface is on the inside. Since the heat-sensitive adhesive resin surface comes into contact with the upper guide roller 4 and the lower guide roller 5, the heat-sensitive adhesive resin melts under the influence of the heated upper laminate roller 2 and lower laminate roller 3, and the upper guide roller 4 and lower guide roller It is necessary for the design to be careful not to stick to 5. In addition, the surface laminate film 6 and the back surface laminate film 7 include a roll wound so that the heat-sensitive adhesive resin surface is on the inside. In this case, the laminate film passes along the path indicated by the dotted line in FIG. It can respond by setting.

In the above embodiment, only the lower guide roller 5 is movable, but it goes without saying that the upper guide roller may be movable.
