Description

[Detailed explanation of the invention] (Field of industrial application) This invention was developed by overlapping the above-mentioned washi paper with a mount impregnated with hot melt adhesive for the purpose of reinforcing the washi paper on which calligraphy or paintings or fish prints have been printed. This invention relates to a heat press device for mounting fittings for pressing and heating.

(Prior art) As a heat press device for mounting materials as described above,
As shown in Figure 3, a box-shaped press table 1 (width: approx. 80 cm, depth: approx. 60 cm, height: approx. 10 cm) is attached to the rear end (right end of the figure) via a bracket 2.
Attach the pair of panel levers 3 so that they can swing up and down,
The center portion of the heat panel 4, which is approximately the same size as the press table 1, is swingably connected between the tips of the left and right panel levers 3, 3, and the tip of the horizontal arm portion 2a of the bracket 2 is attached. One end of the arc-shaped link 5 is connected to the left and right ends 1 formed in the shape of a triangular plate with one side shorter than the other two sides.
One end of the short side of the pair of handle levers 6 is connected with a pin, the other end of this short side is connected to the connection part between the panel lever 3 and the heat panel 4, and the tips of the left and right handle levers 6, 6 are connected. They are connected by rods 7 in the width direction, and when the handle lever 6 is tilted forward as shown in the figure, the heat panel 4 is pressed against the press stand 1, and when the handle lever 6 is rotated clockwise,
It is known that the panel lever 3 rotates upward, and the heat panel 4 moves upward and away from the panel stand 1.

(Problem to be solved by the invention) A link 5 curved in an arc is interposed between the horizontal arm portion 2a of the bracket 2 and the handle lever 6, and when the heat panel 4 is pressed onto the press stand 1, the handle lever 6, the horizontal arm portion 2a of the bracket 2 is located below the horizontal arm portion 2a.
The height of a becomes lower, and the gap between the lower surface of the horizontal arm part 2a and the upper surface of the press stand 1 becomes narrower. Therefore, the heat panel 4 is raised, and the Japanese paper to be reinforced and the backing paper to be pasted on it are overlapped. The work was difficult when loading and unloading. If the height of the horizontal arm portion 2a is set high in order to facilitate the above-mentioned work, the heat panel 4 must be made large in size to be able to be pressure-bonded to the press table 1, which is uneconomical. Further, there were problems in that the mechanism was complicated and large, and lacked ease of use.

(Means for solving the problem) A thin box-shaped press table with felt sheets laminated via a cushion plate on the top surface, and one side of a box-shaped heat panel with an electrically heated heating plate on the bottom surface. A vertical cylindrical spring holder is fixed to the rear surface, and an end of the horizontal part of the L-shaped arm is fixed to the other rear surface so that the vertical part is inserted into the spring holder. and the bent part of the L-shaped arm are rotatably connected with a pin, a roller is attached to the end of the vertical part of the L-shaped arm, and the plate inserted into the spring holder so as to be slidable up and down is biased by the spring. and press it against the roller.

(Function) The press table and the heat panel are connected by a pin via an L-shaped arm and a spring holder, and the heat panel can be swung up and down using this pin as a fulcrum. At this time, the vertical part of the L-shaped arm swings back and forth, and the roller at its tip slides back and forth along the surface of the plate that is pressed against this roller. They are located closer to the heat panel, that is, on the side far from the rear surface of the heat panel, and when the heat panel is open, they are located closer to the front, that is, closer to the rear surface of the heat panel, and are pressed by springs. Therefore, when the heat panel is closed, by positioning the center of the roller slightly behind the connecting pin between the L-shaped arm and the spring holder,
The pressing force of the spring acts in the direction to close the heat panel, while when the heat panel is open, by positioning the center of the roller ahead of the connecting pin, the pressing force of the spring acts in the direction to open the heat panel. act.

(Example 1) In Fig. 1, 11 is a press table with a width of approximately 40 mm.
It is formed in the shape of a rectangular parallelepiped box with a depth of about 50 cm and a height of about 4 cm, and a box-shaped heat panel 12 of almost the same size is connected to the rear end in the form of a hinge.
U-shaped handles 13 on the left and right sides of the front surface of the heat panel 12 are fixed. Above press table 1
1 has a shelf 11a, as shown in FIG. 2, and two felt sheets 14, 14 are placed on this shelf 11a.
and one cushion plate 15 made of foamed polyurethane are alternately laminated, and the felt sheet 14 on the upper surface projects upward from the upper edge of the press table 11. On the other hand, a downwardly convex, spherically curved hot plate 16 is fixed to the lower surface of the heat panel 12, and this hot plate 16 is heated by a plate heater 17 on its upper surface. Note that 18 is a heat insulating sheet, and 19 is a support plate integrated with the heat panel 12.

A rectangular cylindrical spring holder 21 is vertically fixed to the left and right rear surfaces of the press table 11 by mounting brackets 20, a compression coil spring 22 is loaded inside this spring holder 21, and a contact plate 23 is attached to the upper end of the spring holder 21. It will be done. On the other hand, the heat panel 12
The end of the horizontal part 24a of the L-shaped arm 24 is fixed to the rear surface with the vertical part 24b facing downward, and the vertical part 24b is inserted into the spring holder 21 from the opening 21a in the front surface of the upper end of the spring holder 21. The upper end of the spring holder 21 and the bent part of the L-shaped arm 24 are rotatably connected by a pin 25, and the roller 26 attached to the end of the vertical part 24b is inserted into the above-mentioned abutting plate 23. is pressed against the top surface of the However, when the heat panel 12 is closed as shown in FIG. When the heating panel 12 is energized and the heat panel 12 is opened as shown in FIG. It is designed to be biased clockwise. A stopper 24c is provided protrudingly from the bent portion of the L-shaped arm 24, so that the L-shaped arm 24 is approximately
When the heat panel 12 opens by rotating 30 degrees,
The stopper 24c is the back plate 2 of the spring holder 21.
The opening angle of the heat panel 12 is limited by coming into contact with the upper end of the heat panel 1b.

In the above structure, the heat panel 12 is opened as shown in FIG.
When heated, the Japanese calligraphy paper and the mount are thermally bonded,
Next, when you open the heat panel 12, the heat panel 1
The release paper is separated from the hot plate 16 of No. 2, and the mount is separated from the release paper. When the heat panel 12 is opened, the heat panel 12 is held in the open state by the action of the compression coil spring 22, and the opening angle is limited by the stopper 24c, so that the heat panel 12 does not fall backward. do not have. On the other hand, when the heat panel 12 is closed, the heat panel 12 is held in the closed state by the action of the compression coil spring 22. Note that in this example,
Since the hot plate 16 is formed into a spherical shape, the wrinkles of the Japanese paper are smoothed out and the generation of wrinkles is prevented. Furthermore, the L-shaped arm 24 is fixed to the press stand 11,
The spring holder 21 may be fixed to the heat panel 12.

(Effects of the invention) The spring holder is fixed to one of the press table and the heat panel, and the L-shaped arm is fixed to the other, and the two are connected like a hinge, so the structure is simple and suitable for opening and closing lightweight heat panels. For example, it is suitable for pasting on the back of something written on hanshi paper at a calligraphy school. The heat panel can be held in a closed state and an open state, and there is no mechanism on the side for connecting the press stand and heat panel, so it is easy to put in and take out the above-mentioned paper sheets and mounts. , If necessary, you can insert a long piece of paper horizontally, shift the position one by one, and glue it.
