Description

  The present invention relates to a method for manufacturing a braided door in which a brazing material is assembled to an end plate and a braided door.

  Traditionally, the doors that are attached to furniture, doorways, etc., are rectangular plate-shaped end panels, four casings corresponding to the four sides of the end panels, dowels and water-based room-temperature curing adhesive (vinyl acetate emulsion system) It is assembled in a frame shape using an adhesive. The dowels connect the four corners of the four saddle members assembled in a frame shape to improve the assembling strength of the saddle member and the end plate together with the adhesive.

  Each rib is formed with a fitting groove into which the end plate is fitted. A room-temperature-curing adhesive is applied to the fitting groove, and one side of the end plate is fitted into the fitting groove to which the adhesive is applied. The dimensions (length, width, and depth) of such insertion grooves are based on the dimensions of one side of the end plate (length of one side, plate thickness, and insertion length into the insertion groove) for the convenience of assembly. It is formed to have an appropriate length (for example, 0.5 mm) so as to increase.

When the adhesive that bonds the end plate and the brazing material is cured at room temperature (natural drying), it takes approximately one day until the adhesive is cured. There is a problem that the material swells and the central part of the vertical warp warps outward and cannot be attached to furniture, entrances and the like.
In order to solve this problem, the operator stacks a plurality of (a few to a dozen or more) end plates fitted with a saddle material on four sides, and puts an appropriate amount on the longitudinal center of the end plate. A band having a width (for example, 5 cm to 15 cm) is wound and left to stand at room temperature for a day or so for curing the adhesive and curing the braided door.
However, there is a problem in that both ends of the braided door on which the band is not wound, i.e., both ends of the vertical saddle warp outward to form a drum shape, which impairs the beauty of the braided door.

The warp of the vertical fence as described above becomes a serious problem particularly in the case of a braided door having a large aspect ratio, for example, used as a door of a walk-in closet.
Further, since the band is wound manually, the winding work is complicated and requires a long time. Temporarily, when a band is wound around the vertical center part and both ends of the roof door, the warp of the vertical hook is reduced, but the band winding work becomes more complicated and longer.
In addition, warping of the vertical hook is considered to be promoted by the size of the fitting groove larger than the size of one side of the end plate, but when the size of the fitting groove and the size of one side of the end plate are strictly equal, For example, the vertical plate and / or the expansion and contraction of the mirror plate due to temperature, humidity, etc. may cause the mirror plate to be unable to be fitted into the fitting groove.

In order to suppress the warp of the vertical hook, a method of inserting a bar-shaped metal fitting having a U-shaped cross section into the fitting groove of the vertical hook (see Patent Document 1), a method of forming an uneven pattern on the outer surface of the vertical hook (Patent Document) 2), a method using a vertical hook made by folding a wooden board (see Patent Document 3), a method of forming a vertical hook using wood whose dimensional change accompanying shrinkage and swelling is small (see Patent Document 4), and is easy to warp. There has been proposed a method for forming vertical eaves without using natural wood (see Patent Document 5).
Japanese Patent Laid-Open No. 5-1491 JP 2001-207742 A JP 2003-161078 A Japanese Utility Model Publication No. 5-17075 Japanese Utility Model Publication No. 7-14081

However, since the braided door according to Patent Document 1 inserts a bar-shaped metal fitting having a U-shaped cross section into the vertical groove fitting groove, the number of parts and work man-hours increase and the cost of the braided door increases. There was a problem.
In addition, since the glazed door according to Patent Document 2 forms an uneven pattern on the outer surface of the vertical fence, there are problems that the number of work steps increases and the external shape of the vertical fence is limited.
The fence assembly door according to Patent Document 3 forms a vertical gutter by folding a wooden board, and therefore, for example, a vertical gutter formed by cutting out a bar material cannot be used, and a method for forming a vertical gutter is limited. There was a problem.
Furthermore, the gutter doors according to Patent Documents 4 and 5 have a problem that the material of the vertical gutter is limited.

  Moreover, in Patent Documents 1 to 5, there is no mention regarding suppression of warp of warp that occurs because the water of the adhesive penetrates into the saddle and the warp swells.

  The present invention has been made by paying attention to the technology of heating and curing an adhesive that exothermically cures by high frequency, and its main purpose is to bond the central portion of the bonding portion when bonding the brazing material and the end plate. An object of the present invention is to provide a method for manufacturing a braided door and a braided door that can suppress warpage of the braided material by simple and short-time work by high-frequency heating.

  Another object of the present invention is to make it possible to further suppress warpage of the saddle material and the end plate of the end plate by high-frequency heating using an appropriate jig when bonding the end member and the end plate. It is in providing the manufacturing method of a door.

  Yet another object of the present invention is to suppress warping of the brazing material even when the aspect ratio of the mirror plate is large by high-frequency heating the central portion of the bonding portion when bonding the brazing material and the long side of the mirror plate. An object of the present invention is to provide a method for manufacturing a braided door.

  A method for manufacturing a braided door according to a first aspect of the present invention is the method for manufacturing a braided door in which a saddle member in which a fitting groove into which the end plate is fitted is formed is formed on two opposite sides of a rectangular flat plate end plate. Applying an adhesive that generates heat and cure by high frequency to two sides and / or the fitting groove, fitting the two opposing sides into the fitting groove, and heating the center part of the two opposing sides of the bonded portion at high frequency Features.

  According to a second aspect of the present invention, there is provided a method for manufacturing a braided door, in which a rod-shaped jig is provided on the outer side of the saddle member in which the end plate is fitted, and a flat plate is provided along one or both sides of the end plate. It is characterized by arranging a shaped jig.

  According to a third aspect of the present invention, there is provided a method for manufacturing a pair of doors, wherein each of the two opposing sides is a long side of the end plate.

  A awning door according to a fourth aspect of the present invention is a awning door formed by assembling a saddle member in which fitting grooves for fitting the end plate are formed on two opposite sides of a rectangular flat end plate. It is manufactured by any one of the inventions.

In the case of the method for manufacturing the braided door of the first invention and the braided door of the fourth invention, partial high frequency heating is performed when the brazing material and the end plate are bonded.
First, a rectangular flat plate and two brazing materials corresponding to two opposite sides of the mirror are prepared. A fitting groove into which the end plate is fitted is formed in this saddle material.
Next, apply an adhesive to the opposite two sides of the end plate, apply an adhesive to the fitting groove formed in the saddle material, or apply an adhesive to both the opposite two sides and the fitting groove. . The adhesive used here is an adhesive that cures by dielectric heat generated by application of a high-frequency electric field, and in particular, an adhesive that cures at room temperature but is more rapidly cured than it cures at room temperature by heating.
Then, two opposite sides of the end plate are fitted into the fitting grooves of the two brazing materials.

Finally, with respect to the bonded portion, the central portion of the two opposite sides of the end plate is heated at high frequency.
In this case, the adhesive between the central part of the opposite two sides of the end plate and the brazing material is cured first. For this reason, similarly to the case where the vertical center part of the braided door is wound with a band, the central part of the braided door is fixed, and the central part of the braided material can be prevented from warping outward.
In addition, since the moisture of the adhesive is evaporated in a short time by high-frequency heating (more specifically, before the swelling of the brazing material due to the penetration of moisture into the brazing material), the adhesive curing is caused. It is possible to suppress warping to the outside.
From the above, it is possible to improve the beauty of the braided door and to securely attach the braided door to furniture, doorways, and the like.

Here, the reason why the central portion of the bonded portion is heated by high frequency is that the high frequency heating apparatus can be made smaller than when the entire bonded portion is heated by high frequency. If the entire bonded portion is heated with high frequency, the high frequency heating electrode provided in the high frequency heating device needs to be enlarged according to the size of the braided door.
By the way, for example, a vertical door with a small aspect ratio (small difference between the length of a vertical gutter and the length of a horizontal gutter) used as a sink door is a vertical gutter even when a room temperature curing adhesive is cured at room temperature. It is empirically known that the warpage is difficult to occur.
For this reason, it is necessary to manufacture a small electrode (for example, a braided door having a large aspect ratio) by heating the center of the bonding portion with a sufficient range to suppress the warpage of the brazing material. The electrode having a size corresponding to the length of the central portion of the maximum size braid door can be used to accelerate the curing of the necessary and sufficient range of the adhesive.

  It is not necessary to perform high-frequency heating on both ends of the opposite two sides (for example, the long side) of the end plate and two opposite sides (for example, the short side) connected to the two opposite sides. Then, it is allowed to stand for an appropriate time and cured at room temperature. In this case, it is not necessary to use a band for curing the braided door, and it is not necessary to stack the braided door.

Furthermore, the curing by high frequency heating of the adhesive that exothermically cures by high frequency is shorter than the curing at room temperature of, for example, a room temperature curing type adhesive, and a band is formed by stacking a plurality of end plates fitted with brazing materials on a flat surface. The work time is shortened compared with the case where the work of winding is performed.
Furthermore, high-frequency heating of the adhesive that exotherms and cures by high-frequency can be easily performed by setting the end plate fitted with the brazing material on the high-frequency heating device, so that the work procedure is simple.
That is, it is possible to achieve the effects of simplifying the work procedure and shortening the work time even for the braided door where warpage of the saddle material is unlikely to occur.

In the case of the method for manufacturing a braided door according to the second aspect of the invention, high frequency heating is performed using an appropriate jig when the brazing material and the end plate are bonded.
For example, when an end plate fitted in a brazing material is set in a high-frequency heating device, a rod-shaped jig along the brazing material is placed on the outside of the brazing material in which the end plate is fitted, that is, on the side where no fitting groove is formed. By arranging the tool, the brazing material is restrained between the end plate and the jig. For this reason, it can suppress reliably that the curvature of a brazing material generate | occur | produces during high frequency heating.
Further, by arranging a flat jig along one or both sides of the end plate, the end plate is supported or constrained between the jigs. For this reason, it can suppress reliably that the curvature of a mirror plate, a float, etc. generate | occur | produce during high frequency heating.

In the case of the method for manufacturing a braided door according to the third aspect of the invention, an adhesive is applied between the two long sides of the end plate and the two end members, and the end of the end plate is inserted into each of the fitting grooves of the two end members. Fit the two long sides. Finally, with respect to the bonded portion, the central portion of the two long sides of the end plate is heated at high frequency.
For this reason, it is possible to suppress warpage of a saddle member (for example, vertical hook) that is likely to be warped because the aspect ratio is particularly large.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

FIG. 1 is a front view showing a configuration of a braided door 7 according to the present invention, and shows one corner of the braided door 7. Moreover, FIG. 2 is a cross-sectional view for explaining the method for manufacturing a braided door according to the present invention, and shows each of the end plate 10 and the vertical rod 11 constituting the braided door 7.
The end plate 10, the two vertical rods 11, 11 and the horizontal rods 12, 12, and the four dowels 13, 13,... Are each formed using MDF (medium specific gravity fiber plate).
The end plate 10 has a rectangular flat plate shape, and each dowel 13 has a cylindrical shape.

Hereinafter, the vertical hook 11 will be described as an example.
Each vertical rod 11 is a rectangular material having a rectangular cross section assembled to the long side 10a of the end plate 10, and a fitting groove 11a into which the end plate 10 is fitted is formed on one side. Here, the plate thickness of the end plate 10 is 9 mm, the length of the long side 10 a is 1605 mm, and the length of insertion into the vertical rod 11 is 6 mm. Therefore, the width, length, and depth of the fitting groove 11 a are long. It is formed to have a margin of 0.5 mm with respect to the plate thickness, length, and insertion length of the side 10a.

Before assembling the end plate 10 and the vertical gutter 11, the operator winds the wrapping sheet 14 around the vertical gutter 11. The wrapping sheet 14 is made of paper, synthetic resin (for example, polyolefin), etc., protects the surface of the vertical gutter 11 and improves the aesthetic appearance.
Further, the worker applies a predetermined amount of the adhesive 3 to the inside of the fitting groove 11a using a spreader. This adhesive 3 is a water-based vinyl acetate emulsion-based adhesive, and the solvent (moisture) is scattered and cured even at room temperature, but the scattering of the solvent is promoted by the dielectric heating due to the application of the high-frequency electric field, so that the curing is Promoted.
After applying the adhesive 3, the operator fits the long side 10 a of the end plate 10 into the fitting groove 11 a.

  In the same procedure, the operator inserts the four sides of the end plate 10 into the insertion grooves 11a of the vertical hook 11 and the insertion grooves of the horizontal hooks 12 and 12, respectively. At this time, the operator inserts both ends of the dowel 13 into the ends of the vertical hook 11 and the horizontal hook 12 to join the ends of the vertical hook 11 and the horizontal hook 12 together. That is, the operator assembles the vertical gutters 11 and 11 and the horizontal gutters 12 and 12 on the four sides of the end plate 10 in a frame shape, and uses the dowels 13, 13,. Connect the four corners. The dowels 13, 13,... Suppress the displacement of the vertical hook 11 and the horizontal hook 12 and improve the assembling strength of the vertical hooks 11, 11 and the horizontal hooks 12, 12 and the end plate 10 together with the adhesive 3.

The glazed door 7 has a size of 1705 mm long × 397 mm wide and has a large aspect ratio. Moreover, the vertical hooks 11 and 11 are made of MDF that easily swells. For this reason, warp is easily generated in the vertical hooks 11 and 11 when the adhesive 3 is cured.
Using the dowels 13, 13,..., And the adhesive 3, the fitting body 1 (see FIGS. 4 and 5) in which all of the vertical rods 11, 11 and the horizontal rods 12, 12 are fitted on the four sides of the end plate 10 is formed. After that, in order to prevent warping of the vertical rods 11, 11, the braided door 7 is manufactured by the following procedure.

FIG. 3 is a side view showing the configuration of the high-frequency heating device 4 used in the method for manufacturing the braided door. The high-frequency heating device 4 includes a mounting table 40 for mounting various sizes of insertion bodies (for example, the insertion body 1), and a high-frequency oscillator 41. An operation unit 48 for operating the heating device 4 is disposed, and a high-frequency oscillator 41 is continuously disposed on the back surface of the mounting table 40.
4 and 5 are a plan view and a side cross-sectional view for explaining a method for manufacturing the braided door, and shows the fitting body 1 placed on the placement surface 4a of the placement table 40. FIG.

  The mounting body 1 is mounted on the mounting table 40 so that the vertical direction (lateral direction) of the mounting body 1 matches the left-right direction (front-rear direction) of the mounting table 40. Hereinafter, the horizontal direction (vertical direction) is the horizontal direction (vertical direction) of the mounting table 40, and the horizontal direction (vertical direction) is the horizontal direction (vertical direction) of the fitting body 1.

  The mounting surface 4a of the mounting table 40 is a substantially horizontal plane, and as shown in FIG. 4, mounting auxiliary plates 56, 56 having upper surfaces on the left and right sides of the mounting table 40 that are the same height as the mounting surface 4a. Is attached. The length in the front-rear direction (the sum of the lengths in the left-right direction) of the mounting auxiliary plate 56, the mounting table 40, and the mounting auxiliary plate 56 is longer than the lateral width (vertical length) of the fitting body 1. That is, the insertion body 1 is placed on a substantially horizontal plane having a size larger than that of the insertion body 1. For this reason, it is suppressed that an unnecessary external force is applied to a part of the fitting body 1, deformation of the fitting body 1 can be suppressed, and distortion of the completed braid door 7 can be suppressed.

On the mounting surface 4 a of the mounting table 40, rod-shaped outer rulers 51 and 52 that are long in the left-right direction and flat inner rulers 54 and 55 that are long in the left-right direction are arranged. The outer rulers 51, 52 (inner rulers 54, 55) are jigs that are arranged on the outer side in the front-rear direction (inner side) of the vertical rods 11, 11 of the fitting body 1 mounted on the mounting table 40.
The outer rulers 51 and 52 are made of synthetic resin and have substantially the same length as the horizontal length of the placement surface 4a. The outer ruler 52 is screwed and fixed in the vicinity of the innermost part of the placement surface 4a. The outer ruler 51 is screwed and fixed to the front side of the placement surface 4a. The distance between the rear end surface of the outer ruler 51 and the front end surface of the outer ruler 52 is substantially equal to the lateral width of the fitting body 1.

The inner rulers 54 and 55 are made of synthetic resin, and the inner ruler 54 is screwed and fixed to the mounting surface 4 a while being separated from the outer ruler 52 by the width of the vertical rod 11.
The inner ruler 55 is fixed to the placement surface 4a so as to be detachable from the outer ruler 51 by a distance corresponding to the width of the vertical rod 11. More specifically, the inner ruler 55 has a protrusion 55a that is long in the left-right direction on the back surface, and the protrusion 55a is fitted into a groove 10b in the left-right direction formed on the setting surface 4a. 4a is fixed. The protruding portion 55 a may be integrally formed on the back surface of the inner ruler 55, and a separate bar member may be fixed to the back surface of the inner ruler 55.
The thickness of each of the inner rulers 54 and 55 is substantially equal to the protruding height (2 mm) of the vertical hook 11 from one surface of the end plate 10.

The operator sets the inner ruler 55 on the placement surface 4 a, and then abuts one side in the horizontal direction of the fitting body 1 against the front end surface of the outer ruler 52 from the front side, and the side of the fitting body 1. The fitting body 1 is mounted on the mounting surface 4 a between the outer rulers 51 and 52 with the other side of the direction being along the rear end surface of the outer ruler 51.
For this reason, as for the insertion body 1 mounted on the mounting base 40, the positional deviation of the insertion body 1 in the front-rear direction, the warp of the vertical rods 11, 11, and the like are suppressed by the outer rulers 51, 52. Further, since the inner rulers 54 and 55 fill the gap between the placement surface 4a and the end plate 10, warpage, floating, and the like of the end plate 10 are suppressed.

Above the mounting surface 4a of the mounting table 40 and inside the mounting table 40, upper electrodes 421 and 422 and a lower electrode (not shown) are arranged as electrodes for high-frequency heating. Since the lower electrode is disposed below the placement surface 4a, the operation is not hindered.
The upper electrodes 421 and 422 are rectangular plates having substantially the same size and having a horizontal length of 300 mm and a longitudinal length of 50 mm, and are arranged substantially parallel and horizontally at substantially the same height.
The upper electrodes 421 and 422 can both move and stop in the vertical direction (indicated by the white arrow in FIG. 3), and move the upper electrode 421 in the longitudinal direction (indicated by the arrow in FIG. 3). It is supported by the electrode support mechanism 43 so that it can be stopped.

  The electrode support mechanism 43 includes a vertical support bar 431 erected on the innermost part of the mounting surface 4a of the mounting table 40 (further back side of the outer ruler 52) and a bar-shaped vertical axis arranged in the front-rear direction. The moving support unit 432 and the front / rear moving support unit 433 are configured. The vertical movement support part 432 is connected to the support bar 431 at one end so as to be able to move up and down along the support bar 431 and the vertical movement support part 433 is suspended below the vertical movement support part 432. ing. The upper electrode 422 is suspended and fixed to the back end portion of the front and rear movement support portion 433, and the upper electrode 421 is suspended from the front end portion of the front and rear movement support portion 433 so as to be movable back and forth.

  After placing the fitting body 1 on the mounting table 40, the operator operates the operation unit 48 to move the upper electrodes 421 and 422. In this case, as shown in FIGS. 4 and 5, the lower surfaces of the upper electrodes 421, 422 are on the end plate 10, the front side end of the upper electrode 421 is on the vertical rod 11 on the front side, and the back side end of the upper electrode 422. The upper electrodes 421 and 422 move so as to come into contact with the vertical rod 11 on the back side.

In this state, the operator operates the operation unit 48 to drive the high-frequency heating device 4 to the high-frequency oscillator 41 to execute high-frequency heating at an oscillation frequency of about 27.12 MHz for about 30 seconds. That is, the central portion in the vertical direction of the bonded portion between the end plate 10 and the vertical rods 11 and 11 is heated at high frequency.
At this time, the adhesive 3 itself between the end plate 10 and the vertical rods 11 and 11 generates heat internally by dielectric heating by high frequency, and the moisture in the adhesive 3 evaporates and hardens.

After the high-frequency heating is completed, the operator leaves the fitting body 1 for about 30 seconds to cure, and then operates the operation unit 48 to move the upper electrodes 421 and 422 upward to fit from the mounting table 40. Remove the insert 1.
Thereafter, the operator leaves the insertion body 1 for a whole day and night at room temperature. At this time, the bonding portion between the end plate 10 and the horizontal reeds 12 and 12 and both longitudinal end portions of the bonding portion between the end plate 10 and the vertical reeds 11 and 11 are completely cured, and the roof assembly door 7 is completed.

Since the moisture in the adhesive 3 evaporates in a short time by high-frequency heating, the water in the adhesive 3 penetrates into the downspouts 11 and 11, and the downspouts 11 and 11 are prevented from swelling. Moreover, since the longitudinal direction center part of the adhesion part of the insertion body 1 hardens | cures previously by high frequency heating, when leaving a day and night at normal temperature, the case where a band is wound around the longitudinal direction center part of the insertion body 1 and Similar effects can be obtained. From the above, warp of the downboard 11, 11 is suppressed.
The completed glazed door 7 is attached to furniture, doorways, etc. using a hinge, for example. Since vertical warps 11 and 11 of the glazed door 7 are restrained from warping, their aesthetics are improved, and they can be securely attached to furniture, doorways and the like.

The above-described method for manufacturing a braided door can surely suppress the warpage of a long braided door such as a closet, and can contribute to improving and stabilizing the quality of the manufactured braided door. .
Here, since the longitudinal center part of the bonding part of the fitting body 1 is heated at a high frequency to be cured in a short time and the entire longitudinal direction is not heated at a high temperature, the upper electrodes 421 and 422 having the minimum necessary left and right lengths. Can be used. Note that the length in the left-right direction of each of the upper electrodes 421 and 422 is preferably in the range of 20 to 500 mm, but 300 mm is particularly optimal.

  In the high-frequency heating device 4, for safety, the placement surface is within a range that does not hinder the placement of the fitting body 1 on the placement table 40, the movement of the upper electrodes 421 and 422 by the electrode support mechanism 43, and the work of the operator. An aluminum cover 45 is provided to cover 4a. The aluminum cover 45 has an upper surface fixed to the upper portion of the high-frequency oscillator 41 and left and right side surfaces that are respectively suspended from the upper surface and fixed to the left and right side surfaces of the high-frequency oscillator 41. The aluminum cover 45 suppresses entry of foreign matter into the aluminum cover 45 (particularly the placement surface 4a).

Furthermore, the high-frequency heating device 4 includes a photosensor 44 having a light emitting unit 441 disposed at the foremost end of the upper surface of the aluminum cover 45 and a light receiving unit 442 disposed at the foremost end of the mounting surface 4a. The high-frequency heating device 4 is configured such that high-frequency heating can be performed when the light receiving unit 442 receives light emitted from the light emitting unit 441.
When the light receiving unit 442 does not receive the light emitted from the light emitting unit 441, for example, an operator's hand exists in the aluminum cover 45, or the fitting body 1 is being placed on the mounting table 40. Therefore, high-frequency heating is not performed, and high-frequency heating is urgently stopped during high-frequency heating.

  Now, in addition to the awning door 7 having the dimensions of 1705 mm in length × 397 mm in width, the aspect ratio is smaller than the aspect ratio of the awning door 7, but the width is 775 mm × 397 mm in width which is equal to the width of the awning door 7. The braided doors having the dimensions of 565 mm × 397 mm are also formed by the same manufacturing method as the braided door 7 as described above.

  Even when the braided door having dimensions of 565 mm long × 397 mm wide is formed not by the manufacturing method of the present invention but by a conventional manufacturing method in which a room temperature curing type adhesive is cured at room temperature, warping of the vertical wall hardly occurs. However, when forming this braid door with the manufacturing method of this invention, it is not necessary to perform the operation | work which winds a band | pound by stacking a plurality of insertion bodies on a plane, and working time is shortened. Moreover, since the effect similar to the case where a band is wound can be acquired by setting an insertion body in the high frequency heating apparatus 4, a work procedure is simple.

By the way, the braided door having a lateral width of 357 mm shorter by 40 mm than the lateral width of the braided door 7 is also formed by a manufacturing method substantially similar to that of the braided door 7. For this purpose, the arrangement, number, etc. of various jigs in the high-frequency heating device 4 are changed.
FIG. 6 is a side cross-sectional view for explaining another method for manufacturing a braided door, and shows the fitting body 2 placed on the placement surface 4 a of the placement table 40. The insertion body 2 is an insertion body of a braided door having a dimension of 357 mm in width, and in substantially the same manner as the insertion body 1, the four sides of the end plate 20 are fitted to the vertical planes 21, 21 and the two horizontal planes. It fits in the slot.

  The protrusion 55 a on the back surface of the inner ruler 55 is provided not in the front-rear direction center of the inner ruler 55 but in the vicinity of the front (or rear) end, and the horizontally long fitting body 1 is placed on the placing table 40. And the case where the horizontally short fitting body 2 is placed, as shown in FIG. 5 and FIG. 6, by changing the direction of the inner ruler 55 in the front-rear direction, The length of the inner ruler 54 up to the end on the back side is changed. .. Are formed on the mounting surface 4a, and the groove 10b into which the protruding portion 55a is fitted is changed from the front end of the inner ruler 55 to the rear end of the inner ruler 54. It is also possible to change the length up to.

  Also, an outer ruler 53 having a length in the front-rear direction of 40 mm is prepared. The outer ruler 53 is fixed to the placement surface 4a so as to be detachable along the inner side of the outer ruler 51.

The operator sets the outer ruler 53 and the inner ruler 55 on the placement surface 4a, and then abuts the lateral side of the fitting body 2 against the front end surface of the outer ruler 52 from the near side, and inserts The fitting body 2 is mounted on the mounting surface 4 a between the outer rulers 52, 53 by causing the other side in the horizontal direction of the body 2 to be along the rear end surface of the outer ruler 53.
For this reason, as for the insertion body 2 mounted on the mounting table 40, the positional deviation of the insertion body 2 in the front-rear direction, the warp of the vertical rods 11, 11, and the like are suppressed by the outer rulers 51, 52, 53. Further, since the inner rulers 54 and 55 fill the gap between the placement surface 4a and the end plate 20, warpage, floating, and the like of the end plate 20 are suppressed.

The adhesive 3 contains a substance having a large dielectric loss, such as moisture, oil, etc., and therefore, when a high frequency electric field is applied, internal heat is generated due to the dielectric loss, and the adhesive 3 is more quickly than curing at room temperature. The adhesive is not limited to a vinyl acetate emulsion adhesive as long as it is a curing type adhesive. For example, ethylene vinyl acetate copolymer (EVA) resin emulsion, acrylic resin emulsion, and the like.
Moreover, the structure which distribute | arranges a flat jig along both surfaces of the mirror plates 10 and 20 may be sufficient.
