Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall material for cutting two side plates to which a side end surface is cut at a predetermined angle and applying an adhesive thereto, and bonding the applied adhesive surfaces by high-frequency dielectric heating. This is an invention relating to a manufacturing method. As a specific example, a corner portion of a ceramic sizing material forming an outer wall of a building is a corner wall material 1 in which side end surfaces of two narrow plates are abutted at a fixed angle (usually a right angle) and bonded. Are arranged, and a normal plate material A is arranged on the side of the corner wall material for construction. The present invention relates to a method for manufacturing such a wall material.

[0002]

2. Description of the Related Art Conventionally, in order to mainly process wall materials for corners of ceramic sizing materials, for example, an epoxy adhesive is applied to abutting portions and set in a mold for holding two plate materials at a predetermined angle. Then, it was kept in a pressurized state (cold press) for 1 to 2 days to wait for curing of the adhesive. Such a method has a poor production efficiency.
As disclosed in Japanese Patent Application No. 0-60383, an apparatus has been proposed in which the side end faces of two plate members supported at a fixed inclination angle are heated and bonded in a short time by high-frequency dielectric heating.

[0003]

SUMMARY OF THE INVENTION Japanese Patent Application Laid-Open No. H10-6038
In No. 3, two plate materials whose side end faces are cut at a fixed angle are supported on a support base having a substantially mountain-shaped cross section, and both right and left sides of the bonding surface are pressed from above by pressing members so that the bonding surfaces are brought into close contact with each other. A method for applying a high-frequency current to a current is disclosed. In this method, good results were obtained when the plate material was relatively short, but it was found that a problem occurred when the plate material was long. In other words, when the two sheets to be bonded are mainly long-sized ceramic sizing materials, small distortion or internal stress in appearance has occurred,
It has been found that dimensional errors may occur, and that pressing the plate with only a pair of pressing members provided on the left and right sides of the bonding surface may cause a slight shift in bonding position and a variation in bonding strength. .

[0004] In view of the above disadvantages of the prior art, the present invention provides:
A manufacturing method that can apply a constant pressing force to the adhesive surface over the entire length in the longitudinal direction of the plate material to be processed, does not cause a shift in the adhesive surface, and obtains a constant and stable adhesive force over the entire length. It is something to offer.

[0005]

Means for Solving the Problems The two plate materials 1a and 1b to be bonded are cut at a predetermined angle at a side end face, and are coated with an adhesive and butt together. , That is, the two plate members 1a and 1b are held at an inclination angle in which the directions of the bonding surfaces match. In this state, the left and right sides, which are close to the bonding surface, are pressed by upper and lower pressing means for pressing from above and the left and right pressing means for pressing from the lateral direction to bring the bonding surface into close contact, and in this state, a high-frequency current is applied. And heat bonding.

[0006] The force of pressing the two plate members held at the inclination angles in which the directions of the bonding surfaces coincide with each other from above by the vertical pressing means is, as shown by the arrow in FIG. It acts as a force and a component force that presses against the adhesive surface. On the other hand, the force pressing from the lateral direction by the left-right pressing means acts as a component force for pushing the plate material obliquely upward and a component force for pressing the bonding surface, as indicated by arrows in FIG.
Of these component forces, the component force for pushing the plate material obliquely downward and the component force for pushing the plate material obliquely upward cancel each other, so that a large force for pressing the bonding surface acts on the entire plate material.

Further, when a slight displacement occurs due to the distortion of the plate material or the like, the displacement cannot be corrected only by the vertical pressing force or the horizontal pressing force, but the vertical pressing force and the horizontal pressing force cannot be corrected. The normal position is corrected by the balance of the pressing force. In other words, a larger pressing force acts on a portion where the bonding surface is likely to be lifted due to a distortion of the plate material, and as a result, a pressing force as uniform as possible can be applied to the entire bonding surface. The wall material 1 is completed by heating and bonding in a state in which a uniform bonding pressure is applied without causing the generation.

The vertical pressing means and the horizontal pressing means are
The left and right sides of the two plate members supported at the same inclination angle are preferably arranged at symmetrical positions with respect to the bonding position, but the longitudinal arrangement of the vertical pressing means and the horizontal pressing means is, for example, The direction pressing means and the left-right direction pressing means need not necessarily be arranged at the same ratio. However,
Arranging the vertical pressing means and the horizontal pressing means alternately as much as possible is effective in equalizing the pressing force of the bonding surface.

The lateral pressing means may be in the horizontal direction, but need not necessarily be in the horizontal direction. When the lateral pressing means is in the horizontal direction, the upward component acting as a reaction force may be too large.According to experiments by the inventors of the present invention, the lateral pressing means acts slightly downward. Good results were obtained when this was done. However, the magnitude of the diagonally upward inclination angle and the lateral pressing force should be determined in consideration of the balance of the overall force, such as the inclination angle of the supported plate material and the magnitude of the pressing force of the vertical pressing means. It is preferable to select a value that can cause the pressing force to work evenly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an enlarged front view showing a part of an apparatus for manufacturing a wall material for performing a manufacturing method according to the present invention. FIG. 2 is a side view of only a main part of the apparatus for manufacturing a wall material shown in FIG.

Lower platen 2 of high-frequency dielectric heating apparatus shown in FIG.
A pedestal 3 is provided on the upper side for supporting two plate materials to be processed at a fixed angle (usually about 90 degrees). Above the pedestal 3, a cylinder 5 supported by an upper surface plate 4 is provided. The elevating frame 6 driven up and down is arranged. An upper electrode 7 is arranged on the center line of the cradle 3 on the lifting frame 6, and a plate member 1 on the cradle is provided on both left and right sides of the upper electrode 7.
a vertical pressing member 8 for pressing a, 1b from above by a cylinder 9; and a horizontal pressing member 10 for pressing the plate materials 1a, 1b from a lateral direction to a center direction by a cylinder 11.
Is provided.

As shown in FIG. 2, the pedestal 3 has a durable metal plate placed on a horizontal lower platen 2 at an inclination angle of 45 degrees on each of the left and right sides, and the plate members 1a and 1b are placed thereon. I put it. The cradle in which the metal plates are arranged at an inclination angle of 45 degrees on each of the left and right sides is completed by fixing the metal plate on a truncated substantially isosceles triangular pillow material 12 arranged on the lower stool 2. At this time, a gap is formed between the left and right metal plates at the upper end of the receiving base 3, and the lower electrode 15 formed of a resilient spring material protrudes in the gap. As a result, the lower electrode 15 abuts on the lower surfaces of the plate members 1a and 1b placed on the receiving table 3, and the high-frequency dielectric heating of the bonding surface is performed between the lower electrode 15 and the upper electrode 7 disposed above, so that the wall member 1 is formed. Complete.

FIG. 3 shows a specific example of the vertical pressing means. In the illustrated example, two cylinders 9, 9 fixed to the lifting frame 6 are fixed, and the vertical pressing members 8, 8 are respectively operated downward by the cylinders. The vertical pressing members 8, 8 driven by the two cylinders 9, 9 are arranged at symmetrical positions with respect to the center of the cradle below them, and the plate 1
The left and right sides of the adhesive surfaces a and 1b can be pressed under the same conditions. Guide members 8a and 8b are provided outside the vertical pressing members 8, 8 so that the vertical pressing members do not escape to the outside.

FIG. 4 shows a specific example of the left-right pressing means. In the illustrated example, the cylinders 11, 11 are fixed to fixed cylinder mounts 11a, 11b protruding downward at symmetrical positions on both left and right sides of the lifting frame 6, and the left and right pressing members 10 are fixed inward. , 10 advance and retreat, so that the upper portions of the plate materials 1a, 1b, which are the workpieces, can be pressed from the left and right sides under the same conditions. The left and right pressing members 10 and 10 disposed on the left and right sides of the elevating frame 6 press the plate material not diagonally but slightly (in the drawing, the inclination angle is 15 degrees) from diagonally upward to diagonally downward.

FIG. 5 shows the structure of an upper electrode for high-frequency dielectric heating. The upper electrode 7 has a rod shape continuous in the longitudinal direction, and is located directly above the center line of the cradle 3. The rod-shaped upper electrode 7 is guided downward from the lifting frame 3 so as to allow a certain dimension of lifting and lowering.
And guards on both sides
Is projected. The guard 14 is formed of a non-conductive material such as a synthetic resin material, and protrudes below the upper electrode 7 by a certain dimension. When the lifting frame 6 descends,
First, the tip of the guard 14 comes into contact with the surface of the plate material 1a, 1b, which is the workpiece, and thereafter, the guide rod 13 of the upper electrode 7 and the lifting frame 3 move freely. As a result, a constant gap X is maintained between the upper electrode 7 and the upper end of the plate material, and the adhesive overflowing from the bonding surface can be prevented from adhering to the upper electrode 7 and to the side surfaces of the plate materials 1a and 1b. .

Vertical pressing member 8 and horizontal pressing member 10
May be appropriately arranged in an arbitrary ratio such as 1: 2 or 2: 3 in the length direction. In the illustrated example of FIG. 1, the vertical pressing members 8 and the horizontal pressing members 10 are alternately arranged, and 1a and 1b
Can be pressed as uniformly as possible as a whole.

Next, a description will be given of a manufacturing process of a wall material 1 for a corner, for example, in which two plate materials 1a and 1b are abutted and adhered at a fixed angle. The plate materials 1a and 1b to be joined are
One of the side end faces is cut at a predetermined angle (when the side end face is to be bonded at 90 degrees, the side end faces are cut at 45 degrees), an adhesive is applied to the cut surfaces, and the cut surfaces are placed on the receiving table 3. The plate material to be bonded is placed so that the side surface to be bonded is located at the upper position, and the bonding surfaces face each other. At this time, take care that the adhesive surfaces can contact each other, and if the width of the plate material does not match,
The plate material is placed on both skirt portions of the cradle 2 with the spacer 12 interposed therebetween.

Thereafter, when the lifting frame 6 is lowered, the guard 14 of the upper electrode 7 comes into contact with the surface of the plate material placed on the pedestal 2, and the upper electrode 7 and the lower electrode 15 dielectrically heat the bonding surface. Are placed in a positional relationship that allows In this state, the cylinder 9 is operated to press the upper portions of the plate members 1a, 1b in the vertical direction with the vertical pressing members 8, 8, and the cylinder 11 is operated to move the left and right pressing members 10, 10
Pressing the upper part of the plate material 1a, 1b in the left and right direction, and applying a high-frequency current in a state where the adhesive surface is pressed and adhered by the pressing force in the vertical direction and the pressing force in the left-right direction, the high-frequency dielectric heating causes the plate material 1a, 1b to be pressed. The adhesive during 1b is heated to complete the bonding operation.

When the plate members 1a and 1b are pressed downward by the vertical pressing members 8 shown in FIG. 3 as indicated by white arrows, the plate members have a downward component force and an inward component force as indicated by black arrows. Works. When the plate members 1a and 1b are pressed downward as shown by white arrows with the left and right pressing members 10 and 10 shown in FIG. 4, the plate members have upward component force and inward component components as shown by black arrows. Force acts. Pressing the plate with only the vertical pressing means not only presses the bonding surface but also separates the plate, so if the relevant dimensions of the plates 1a, 1b and the cradle are accurate, an even pressing force on the bonding surface However, if there is a slight distortion or dimensional error, there is a possibility that one of the plate members moves downward and the bonding position is shifted or the bonding pressure is insufficient, so that sufficient strength cannot be obtained. Further, when the plate is pressed only by the left-right pressing means, the plate has not only a function of pressing the bonding surface but also a function of pushing up the plate, which may cause displacement of the bonding surface.

In the present invention, by using the vertical pressing means and the horizontal pressing means in combination, the force of pressing the plate material downward and the force of pushing the plate material upward are canceled out, and only the force of pressing the adhesive surface acts effectively. Furthermore, against minute displacement of the plate due to the distortion of the plate, etc., the pressing force from up, down, left and right has the function of correcting the position by itself, so that it can be accurately positioned over the entire length of the plate to be processed. Heat bonding is performed with an even pressing force.

[0021]

According to the method for manufacturing a wall material according to the first aspect of the present invention, even if the two plate materials to be bonded have a long dimension, they have a precise positional relationship over their entire length, and High-frequency dielectric heating can be performed in a state where an even bonding pressure is applied, and a wall material that is uniformly bonded without partial bonding failure or the like can be provided.

According to the second and third aspects of the present invention, it is possible to select a state in which the combination of the vertical pressing force and the horizontal pressing force is as balanced as possible and to provide a uniformly bonded wall material. Conditions can be set.
