Description

The present invention relates to a method for manufacturing a frame with a mullion and an apparatus for manufacturing a frame with a mullion, in which a frame made of a thermoplastic resin is arranged in a rectangular frame shape, a mullion is arranged in the middle, and each of them is mutually arranged. The present invention relates to a method and an apparatus for welding to form a frame with a mullion.

In recent years, as a building material, a frame body in which a frame material made of a thermoplastic resin is assembled is often used. Examples of such a resin frame include a resin frame of a resin sash, a resin frame material constituting a resin shoji frame, and the like.
In the production of such a resin frame, thermoplastic resin frame members are arranged on four sides of a rectangular frame, and the ends of the frame members are welded to each other (Patent Documents 1 to 1). 4).
Each end face (which becomes a welded surface to be welded) of the frame material is formed so as to be inclined with respect to the longitudinal direction of the frame material, and by welding these inclined welded surfaces to each other, the frame materials intersect each other in the intersecting direction. And the corners of the frame are formed. For example, it is common that the inclinations of the welded surfaces are 45 degrees so that the frame members to be welded are 90 degrees. In such a setting, the welded surface extends along the diagonal direction of the frame.

Patent Document 1 describes a manufacturing apparatus for manufacturing the above-mentioned resin frame.
In this manufacturing apparatus, a holding member that holds the end portions of the frame material and a holding member driving mechanism that moves the holding member inward in the rectangular frame shape are held at four corners of the rectangular frame shape that serves as the frame body. It includes a heater plate that heats the inclined welding surface at the end of the frame material, and a heater plate driving mechanism that moves the heater plate along the welding surface.
Each of these mechanisms is supported by the same base member and is installed at four corners of a rectangular frame that serves as a frame. The base member is movable in the vertical and horizontal directions of the frame material at each of the four corners, and its position can be adjusted to support the manufacture of various frame bodies.

In this manufacturing apparatus, following preparations such as holding the frame material (preparation process), the welded surfaces are heated (heating process), the welded surfaces are crimped to each other (crimping process), and the formed frame is taken out. (Removal process) is performed.
In the preparatory step, a plurality of frame materials molded from thermoplastic resin are arranged in a rectangular frame shape, and the welding surfaces at both ends of each are arranged along the diagonal direction of the rectangular frame shape, and the welding surfaces of adjacent frame materials are arranged. Keep them facing each other.

In the heating step, a heater plate is arranged between the welding surfaces facing each other, the heater plate is brought into contact with the welding surface, and the welding surface is heated. During heating, the welded surface is not melted and the frame material is not moved. When the welding surface is sufficiently melted, the heating of the welding surface by the heater plate is continued, and the frame material is slightly moved inward in a rectangular frame shape according to the melting allowance generated by the melting of the welding surface. The resin on the welded surface spreads along the heater surface with heating and melting, but the movement of the frame material ensures contact between the welded surface including the spread molten resin and the heater surface. Sufficient heating is maintained.

In the heating step, when the welded surface is sufficiently melted, preparation for crimping is performed. First, the frame material is moved outward in a rectangular frame shape, and the welded surface is separated from the heater plate. Further, the heater plate is retracted from between the welding surfaces toward the outside of the frame body so that the adjacent welding surfaces are directly opposed to each other.
In the crimping process, the frame material is moved inward in a rectangular frame shape, the welding surfaces facing each other are brought into close contact with each other, and the frame material is further pressed with a specified force. As a result, the welding surfaces facing each other are crimped to each other, and the frame members on the four sides are connected at the four corners to form a rectangular frame-shaped frame body.
In the taking-out step, the holding of each frame material by the holding member is released, and the frame material is taken out as a frame body.
A resin frame is manufactured by such a frame manufacturing apparatus and manufacturing method.

In the production of the frame body as described above, the spread molten resin may appear on the surface of the frame body, which may cause a quality problem as so-called burrs. For this reason, various problems of burr generation and joint strength due to spreading have been studied conventionally.
In Patent Document 1, the periphery of the welding surface at the end of the frame material is surrounded by a holding member to prevent the molten resin from spreading to the outer peripheral side of the welding surface along the surface of the heater plate, and on the outside of the frame material. The occurrence of burrs is suppressed.
In Patent Document 2, the holding member is brought into contact with the exposed surface, which affects the appearance of the product, among the periphery of the welded surface at the end of the frame material, and the molten resin to be a burr is guided to the inside of the frame material. .. In Patent Document 2, burrs generated on the back side are used as a joint cross-sectional area to improve the joint strength.

On the other hand, as the frame body manufactured as described above, a cosmetic surface material may be laminated on the surface. In such a frame body with a surface material, in addition to the above-mentioned problem of burr generation, a problem of joint strength due to entrainment of the surface material has been studied.
In Patent Document 3, when joining a frame material in which a surface material having a low welding strength is stretched to a base material having a high welding strength, the area of the base material is made wider than the area of the surface material in the cross section of the joint portion. There is.

In Patent Documents 1 to 3 described above, the temperature is raised by a heater plate and melted by heating, but melting by high-frequency vibration or friction is also used as a means for melting the welded surface of the frame material.
Patent Document 4 exemplifies a heating element in which a heating element is arranged between facing welding surfaces, and the heating element melts the welding surface by high-frequency vibration. Then, a structure is adopted in which the heating element and the holding member of the frame material are mechanically connected and moved diagonally in cooperation with each other so that the welding surface of the welded surface can be reliably continued to be melted by the heating element. ..

By the way, in the rectangular frame body described above, the frame members are arranged on the four sides of the rectangular frame shape, and the respective ends are joined to form a frame body.
On the other hand, as a building material for continuous windows or stepped windows, a frame with a mullion having a mullion in the middle is used.
The frame with mullion forms a rectangular frame-shaped frame with four frame members (a pair of first frame members and a pair of second frame members), and the intermediate portions of the first frame members are connected to each other by mullion members. (See FIG. 4 of Patent Document 5).

Even in the manufacture of such a mullion-mounted frame, the manufacturing apparatus having the holding member and the heater plate described above is used for joining the frame members at the corners, and the frame members are inclined formed at the ends of the frame members. Welding surfaces are welded together.
On the other hand, in order to join the cubic members, the ends of the cubic members are formed in a triangular shape, a V-shaped groove is formed in the middle portion of the first frame member, and these are fitted and welded.

That is, a welding surface inclined to the outside of the triangle is formed at the end of the cubic member. A V-shaped groove corresponding to the end of the cubic member is formed in the middle portion of the first frame member, and a pair of inclined welding surfaces are formed inside the groove.
Then, the triangle of the cubic member and the V-shaped groove of the first frame member face each other, a heater plate is arranged between the welding surfaces, and the resin on the welding surface is heated and melted. Further, the pair of first frame members are brought close to each other, whereby the triangular welded surface of the cubic member and the welded surface of the V-shaped groove of the first frame member can be welded.

The welding of the end portion of the mullion material and the intermediate portion of the first frame material is performed by welding the four corners (the first frame material and the second frame material) for assembling the above-mentioned frame body (frame body without mullion). It is desirable to perform it at the same time as welding).
In the conventional manufacturing process, the movement of the frame material accompanied by heating in the heating step described above is limited to the movement of the cubic material and the second frame material in the continuous direction (direction intersecting with the first frame material) (Patent Document 5). See FIG. 13).

That is, in the manufacturing apparatus, the mullion and the pair of second frame members are held in parallel at predetermined intervals according to the completed size of the mullion frame, and their ends are aligned with each other. Further, the first frame member is held along each end of the cubic member and the pair of second frame members. At this time, the pair of first frame members are held at predetermined intervals larger than the completed size of the mullion frame. That is, the first frame member is arranged apart from each end of the cubic member and the pair of second frame members.

Then, a heater plate is arranged along each welding surface of the first frame material, the second frame material, and the cubic material, and heating is performed to heat and melt each welding surface.
At the time of heating, the pair of first frame members are moved in directions close to each other, and the molten resin having a predetermined melting allowance is developed along the surface of the heater plate. However, the second frame material is not moved.

When the heat melting becomes sufficient, the heater plates are retracted, the pair of first frame members are further moved in the proximity direction, and the welding surfaces facing each other are crimped to each other. As a result, the end portion of the first frame member and the second frame member are joined, and the intermediate portion of the first frame member and the cubic member are joined at the same time.
As described above, a rectangular frame shape is formed by the pair of the first frame material and the pair of the second frame material, and a mullion material connecting the intermediate portions of the pair of the first frame material is installed inside the rectangular frame material. A frame is formed.

Japanese Unexamined Patent Publication No. 2008-221608 Japanese Unexamined Patent Publication No. 2010-150819 JP-A-2010-150820 U.S. Pat. No. 7,854,246 U.S. Patent Application Publication No. 2003/015570

In the conventional method for manufacturing a frame with a mullion described above, there is a problem that it is difficult to arrange the welding marks of the joint portion between the first frame material and the second frame material into a preferable shape.
That is, in the above-mentioned conventional method for manufacturing a mullion frame, the mullion and the pair of second frame members are arranged in parallel at predetermined intervals according to the completed size of the mullion frame for welding. .. And, during the subsequent heating, each position remains fixed. On the other hand, in the first frame material, the welding allowance is moved during heating.
In the welding operation with such a setting, the position where the welding surface of the second frame material and the welding surface of the first frame material first come into contact is the final joining of the first frame material and the second frame material. It will be a position displaced from the position. Then, during the welding operation, the welding surface of the second frame material and the welding surface of the first frame material move relatively by the amount corresponding to the above-mentioned displacement. Therefore, there is a problem that the molten resin on the welded surface is dragged and a well-organized welding mark cannot be formed.

Further, in the above-mentioned conventional method for manufacturing a frame with a mullion, the spread of the molten resin along the heater plate is not always in a preferable state at the joint portion between the first frame material and the second frame material. ..

In Patent Document 1 or Patent Document 2 described above, the welding surface at the end of the frame material is surrounded by a holding member, and the molten resin is guided to the inside of the frame material to suppress the generation of burrs on the surface of the frame material. doing.
In these configurations, even if the occurrence of burrs cannot be completely prevented, if the degree of burrs is slight, post-processing such as cutting can sufficiently cope with it.

On the other hand, in the heating step described above, when the frame material is moved inward by the holding member, the molten resin may be excessively spread inside the frame material.
In such a case, most of the molten resin faces the inside of the frame material, the molten resin on the outside is insufficient, and a concave boundary line may be formed at the joint portion between the frame materials.
Further, in the frame material covered with the surface material, even the surface material may go toward the inside of the frame material and enter the welded portion of the base material. In such a state, the welding between the base materials is insufficient, the bonding strength is not sufficiently secured, and the product cannot be used.

In order to avoid the excessive spread of the molten resin inward of the frame material as described above, it is conceivable to adjust the movement of the frame material inward by the holding member in the heating step.
However, there is a limit in control accuracy in driving the holding member that executes the movement of the frame material inward in the frame body. Further, in the manufacturing apparatus of Patent Documents 1 to 3, when the welded surface is dragged outward along the surface of the heater plate due to the movement of the frame material toward the inside of the frame, particularly when the frame is formed on the frame. On the inner side of the corner portion, there is a problem that the spread of the molten resin tends to be mainly inward of the frame material (outward of the frame).

Therefore, an effective measure for avoiding the excessive spread of the molten resin inside the frame material has been required.
On the other hand, changing the conventional device configuration as in Patent Documents 1 to 3 described above is not preferable in terms of equipment cost, and it has been desired that the same device configuration can be used.

An object of the present invention is to provide a method for manufacturing a mullion frame body and an apparatus for manufacturing a mullion frame body capable of adjusting the shape of a welded portion.

In the method for producing a frame with a square of the present invention, a pair of the first frame and a pair of the second frame are formed by using a first frame, a second frame and a square molded from a thermoplastic resin. It is arranged in a rectangular frame shape, and the welding surfaces at both ends are arranged along the diagonal direction of the rectangular frame shape so that the welding surfaces of the adjacent first frame material and the second frame material face each other. , The cubic member is arranged in the intermediate portion of the pair of the first frame members, and the welding surface of the end portion of the cubic member and the welding surface of the intermediate portion of the pair of the first frame members are opposed to each other. A heater plate is arranged between the welding surfaces, the heater plate is brought into contact with the welding surface, the facing welding surfaces are heated and melted, and the heater plate is separated from between the welding surfaces. This is a method for manufacturing a frame with a cubata in which the molten welded surfaces are crimped to each other and the first frame material, the second frame material and the cubic material are joined, and when the welded surfaces are heated, the said When the pair of the first frame members are moved inward in the rectangular frame shape according to the melting allowance generated by the melting of the welded surfaces and the welded surfaces are crimped to each other, the pair of the first frame members and the pair It is characterized in that each of the second frame members is moved inward in the rectangular frame shape.

In the present invention as described above, the frame body can be manufactured by welding the first frame material, the second frame material and the cubic material by carrying out the same preparation, heating and crimping steps as described above. ..
At this time, when the welded surface is heated, by moving only the pair of first frame members inward in a rectangular frame shape, the cubic members and the pair of second frame members to be joined to the first frame members are The same melting allowance can be moved for each.
Further, when the welding surfaces are crimped to each other, the pair of first frame materials and the pair of second frame materials are moved inward in a rectangular frame shape, whereby the welding surface of the first frame material and the second frame material are formed. It is possible to make the welded surfaces of the above in the same moving state, and it is possible to eliminate the relative movement of both welded surfaces and arrange the welding traces.

In the method for manufacturing a frame with a mullion of the present invention, when the first frame material is moved inward in the rectangular frame shape while heating the welding surface with the heater plate, the heater plate is moved to the first. It is desirable to move the frame material along with the inward movement of the rectangular frame shape.
In the present invention as described above, in order to transfer the same melting allowance to the cubic member and the pair of the second frame members to be joined to the first frame member described above, only the pair of the first frame members are rectangular frames. The heater plate can be moved synchronously with respect to the welding surface when the operation of moving the shape inward is performed, whereby the contact between the heater plate and the welding surface is maintained and the heating state is continued. Can be done.

In the method for manufacturing a frame with a mullion of the present invention, when the first frame material is moved inward in the rectangular frame shape while heating the welded surface with the heater plate, the first frame material is welded. It is desirable to move the corner heater plate between the surface and the welding surface of the second frame material relative to the welding surface inward in the rectangular frame shape.

In the present invention as described above, when the first frame material is moved inward in a rectangular frame shape while heating the welded surfaces of the first frame material and the second frame material with the square heater plate, the welded surface is subjected to. By relatively moving the corner heater plate inward in a rectangular frame shape, a part of the molten resin on the welded surface of the first frame material and the second frame material that are in contact with the corner heater plate is formed into corners. It is guided inward in a rectangular frame shape together with the heater plate.

That is, the molten resin is spread outward by the inward movement of the frame material as in the conventional case, and these are spread by the relative movement of the corner heater plate and the welding surfaces of the first frame material and the second frame material. A part of the molten resin on the welded surface is spread inward in a rectangular frame shape. This makes it possible to avoid excessive spreading of the molten resin inside the frame material.
In particular, when a frame material with a surface material is used as the first frame material and the second frame material, the surface material can be guided inward in a rectangular frame shape, and the surface material enters the inside of the frame material. This can be prevented and welding between the base materials can be ensured.

In the method for manufacturing a mullion frame of the present invention, the corner heater plate has a speed higher than the component of the inward moving speed of the rectangular frame of the first frame material in the direction along the welded surface. Is desirable to move inward of the mullion frame.

With such a setting of the present invention, it is possible to obtain an effect of guiding a part of the molten resin on the welded surface in contact with the corner heater plate inward in a rectangular frame shape together with the corner heater plate. For example, when the welding surface and the corner heater plate are set to 45 degrees with respect to the longitudinal direction of the frame material, the calculation is performed at 1.414 times the inward movement speed of the frame material (square root of 2 times). Based on the velocity of the directional component along the welding surface, it can be set to, for example, 1.1 times the relative velocity.

In the relative movement between the corner heater plate and the welding surface, a drive mechanism may be provided on the first frame material and the corner heater plate, respectively, and the movement speed of each may be adjusted to realize the relative movement. A drive mechanism may be provided between the first frame and the corner heater plate so that both can be moved directly. In short, in the present invention, it is sufficient that the corner heater plate and the welding surface can be relatively moved so that a part of the molten resin on the welding surface can be guided inward in a rectangular frame shape.

The method of manufacturing a standing with frame towards the present invention, the first frame member, as the second frame member and the side elevational material, used as the surface material on the surface of the base material is stretched, the said heater plate first It is desirable to set the relative speed with respect to one frame material to 1.5 times or more and 2 times or less.
In the present invention, the setting range of the relative speed of the heater plate with respect to the frame of 1.5 times or more and 2 times or less is such that the molten surface material faces the inside of the mullion frame along the surface of the corner heater plate. It is based on the finding that it is suitable as the speed at which the molten substrate spreads outward along the surface of the corner heater plate, except for a part, in the direction of the mullion frame.

In the present invention as described above, the surface material can be guided exclusively inward in the rectangular frame shape while spreading the base material outward and inward in the rectangular frame shape along the corner heater plate. Therefore, it is possible to prevent the surface material from entering the inside of the first frame material and the second frame material, and it is possible to ensure welding between the base materials.
The situation in which such induction is performed also depends on the characteristics of the resin constituting the first frame material and the second frame material, the heating temperature, and the moving speed of each part. Therefore, it is desirable to perform test processing in advance and make adjustments so that appropriate conditions for each part can be obtained.

In the method for manufacturing a mullion frame of the present invention, a holding member for holding the first frame member, a holding member driving mechanism for moving the holding member inward in a rectangular frame shape, and a corner heater plate. Using a welding device having a corner heater plate driving mechanism for moving the corner heater plate along the welding surface, the moving speed of the holding member driving mechanism and the moving speed of the corner heater plate driving mechanism.

The intermediate portion holding member 50 is similar to the end holding member 10 described above in that it is formed in a block shape and has a holding hole 52.
Further, a holding member driving mechanism 51 (intermediate portion holding member driving mechanism 51) is connected to the intermediate portion holding member 50, and the V-shaped 3V of the first frame member 2A is formed into a cubic member by the intermediate portion holding member driving mechanism 51. It can be moved toward the triangular 3T of 6.

The pair of welding surfaces 3 forming the triangular 3T at the end of the cub member 6 by the cub member holding member 40 and the intermediate portion holding member 50 are the V of the first frame member 2A held by the end holding member 10. They are arranged to face each other at predetermined intervals on a pair of welding surfaces 3 having a character shape of 3V.
A V-shaped intermediate heater plate 60 is arranged between the triangular 3T and the V-shaped 3V.

The intermediate heater plate 60 is formed by joining two square heater plates 20 described above to form a V shape, and has a pair of triangular 3T welding surfaces 3 and a V-shaped 3V pair of welding surfaces 3. Each of the welded surfaces 3 can be heated and melted by being installed between the two.
The intermediate heater plate 60 is supported by the intermediate base member 61, and the heater plate drive mechanism 62 (intermediate heater plate drive mechanism 62) is connected to the intermediate base member 61.

The heater plate drive mechanism 62 moves the intermediate heater plate 60 in a direction orthogonal to the first frame member 2A and the cubic member 6 (direction orthogonal to the display in FIG. 1), whereby the intermediate heater plate 60 is triangular. It can be evacuated from the interval portion of the shape 3T and the V-shape 3V.
The intermediate heater plate drive mechanism 62 only needs to be able to drive the intermediate heater plate 60 from the forward position within the interval of the triangular 3T and the V-shaped 3V to the shunting position, and is a highly accurate drive mechanism such as a ball screw. It can be configured with a simpler drive mechanism, an air cylinder, or the like.

The manufacturing device 9 includes a control device 7 that controls the holding member drive mechanisms 11, 51, heater plates 20, 60, and heater plate drive mechanisms 21, 62 described above.
The control device 7 is a computer system that controls each part based on a pre-registered operation program. In the present embodiment, the frame material 2 and the mullion 6 are welded by operating each part according to the procedure shown in FIG. The frame body 1 with a mullion can be manufactured.

FIG. 2 shows an operation procedure in the manufacturing apparatus 9 executed by the control apparatus 7.
In manufacturing the mullion-equipped frame 1, first, the frame material 2 (first frame material 2A, second frame material 2B) and the mullion 6 to be joined are set in the manufacturing apparatus 9 by the preparation step S1.

In the preparation step S1, the holding member driving mechanisms 11 and 51 are operated by a command from the control device 7, and the holding members 10 and 50 are retracted (moved outward from the frame 1) to predetermined mounting positions, respectively (process). S11, S12).
At this time, the heater plate drive mechanisms 21 and 62 are maintained at the retracted positions on the outside of the frame body 1.

When the holding members 10 and 50 stop at the mounting position, the control device 7 waits for an instruction by the operator.
During this time, the operator sequentially carries four frame members 2 (a pair of first frame members 2A and a pair of second frame members 2B) and a cubic member 6 into the manufacturing apparatus 9. Then, both ends of the carried-in first frame member 2A and second frame member 2B are held by a pair of holding members 10. Further, both ends of the carried-in cubic member 6 are held by the holding member 40 (process S13).

When the frame member 2 and the cubic member 6 are set, the process in the control device 7 is restarted by the operation of the operator, and the heating step S3 is executed.

In the heating step S3, in the corner portion, the heater plate drive mechanism 21 is operated by a command from the control device 7, the corner portion heater plate 20 is advanced (moved inward of the frame body 1), and the end holding member 10 is used. The corner heater plate 20 is introduced at a distance between the welding surface 3 of the first frame material 2A and the welding surface 3 of the second frame material 2B held so as to face each other (process S21).
At the same time, in the corner heater plate 20, heating is started and the surface of the corner heater plate 20 is heated by a command from the control device 7 (process S22).

Further, in the intermediate portion of the first frame member 2A, the intermediate portion heater plate drive mechanism 62 is operated by a command from the control device 7, the intermediate portion heater plate 60 is advanced, and the interval between the triangular 3T and the V-shaped 3V is formed. It is arranged inside, that is, between the welding surface 3 of the triangular 3T and the welding surface 3 of the V-shape 3V, which are held facing each other by the cubic member holding member 40 and the intermediate portion holding member 50 (process S23).
At the same time, in the intermediate heater plate 60, heating is started and the surface of the intermediate heater plate 60 is heated by a command from the control device 7 (process S24).

While the temperature rise of the heater plates 20 and 60 progresses, the end holding member drive mechanism 11 is operated by a command from the control device 7, and the holding member 10 of the first frame member 2A is moved to a predetermined heating end position Ph1. It is advanced toward (moves inward of the frame 1), and the holding member 10 of the second frame member 2B is advanced (moved inward of the frame 1) toward the predetermined heating contact position Ps2 (process S25). , S26).
When the holding member 10 of the first frame member 2A reaches the heating contact position Ps1 which is a passing point before the heating end position Ph1, and the holding member 10 of the second frame member 2B reaches the heating contact position Ps2, the first The welded surfaces 3 of the 1st frame material 2A and the 2nd frame material 2B are brought into surface contact with the surfaces of the heater plates 20 and 60, respectively (process S27). Then, as the heating progresses, each welding surface 3 is heated from the surface to a predetermined depth (treatment S28).

Heating of the welding surface 3 at the ends of the first frame material 2A and the second frame material 2B by the corner heater plate 20 (treatment S22), and the welding surface 3 of the V-shaped 3V and the triangular 3T by the intermediate heater plate 60. While continuing the heating (processing S24), the end holding member driving mechanism 11 and the intermediate holding member driving mechanism 51 for driving the first frame member 2A, and the corner heater plate 20 are further subjected to a command from the control device 7. The corner heater plate drive mechanism 21 to be driven is continuously operated.

The end holding member driving mechanism 11 and the intermediate portion holding member driving mechanism 51 of the first frame member 2A continuously advance the holding member 10 of the first frame member 2A from the above-mentioned heating contact position Ps1 (process S25). (The pair of first frame members 2A move inward toward each other in the frame body 1). In this advance, the total movement distance during the heating step S3 is set to a predetermined melting allowance Dh (process S31).
By this advance, the molten resin of each welding surface 3 is compressed and spreads along the surfaces of the corner heater plate 20 and the intermediate heater plate 60 (process S32).

The expansion of the welded surface 3 due to the advancement of the end holding member driving mechanism 11 and the intermediate portion holding member driving mechanism 51 of the first frame member 2A occurs exclusively outward of the frame body 1.
As shown in FIG. 3, when there is a movement 10M in which the end holding member 10 moves forward, as shown in FIGS. 4 and 5, the ends of the first frame member 2A and the second frame member 2B are corner portions, respectively. Of the surface of the heater plate 20, the frame 1 is pushed and bent outward (upper left direction in FIGS. 4 and 5). As a result, the molten resin of the welded surface 3 produces an outwardly spread portion 31 of the frame body 1.

In contrast to such outward extension of the frame body 1, in the present embodiment, the square heater plate 20 is relatively moved with respect to the welding surface 3 to generate inward extension of the frame body 1. ..
The corner heater plate drive mechanism 21 advances the corner heater plate 20 to the heating end position Ph1 (moves inward of the frame body 1). In this advance, the total movement distance during the heating step S3 is set to a predetermined adjustment amount Da (Da = Ph1-Ps1) (process S33).

The adjustment amount Da in the corner heater plate drive mechanism 21 is 1. It is set to be larger than 414 times (square root of 2).
With such a setting, the surface of the corner heater plate 20 moves relative to the welding surface 3 of the first frame member 2A inward (lower right direction in FIG. 4) of the frame body 1 (lower right direction in FIG. 4). (See FIG. 4).
On the other hand, since the second frame material 2B does not move at this point, the surface of the corner heater plate 20 faces inward of the frame body 1 with respect to the welding surface 3 of the second frame material 2B (lower right in FIG. 4). It will move relative to the direction) (see FIG. 5).
By advancing the corner heater plate drive mechanism 21 in this way, a part of the molten resin is generated inward in the frame 1 in the above-mentioned spreading of the welded surface 3 of the corner (treatment S32). ..

As shown in FIG. 3, when there is a movement 20M in which the corner heater plate 20 moves forward, as shown in FIGS. 4 and 5, a part of the molten resin of the welding surface 3 is on the surface of the corner heater plate 20. Along the same direction, the frame body 1 is dragged inward (in the lower right direction of FIGS. 4 and 5) to form an extension portion 32 in the opposite direction to the above-mentioned extension portion 31.
The spread portion 32 is mainly formed of the molten resin of the surface material 5 stretched on the side thereof, and also includes a part of the molten resin of the base material 4.

As described above, in the heating step S3 of the present embodiment, the end holding member driving mechanism 11, the intermediate portion holding member driving mechanism 51, and the heater plate driving mechanism 21 are used to provide the end holding member 10 and the corner portion of the first frame member 2A. The heater plate 20 is moved, and in particular, the surface of the corner heater plate 20 moves relative to the welding surface 3 inward of the frame 1, so that the frame 1 is added to the normal spreading portion 31. The inward-facing spreading portion 32 of the can be formed.

On the other hand, on the surface of the intermediate heater plate 60, melting progresses on the welding surface 3 of the V-shaped 3V and the triangular 3T, and the first frame member 2A advances (process S31, end holding member drive mechanism 11). And by the intermediate portion holding member drive mechanism 51), the molten resin spreads on the surface of the intermediate portion heater plate 60.
At this time, the intermediate heater plate 60 is not advanced due to melting by the intermediate heater plate drive mechanism 62.

When the processes S31 to S33 in the heating step S3 are completed, the control device 7 retracts the end holding member drive mechanism 11 of the first frame member 2A to the detachment position Pd1 (process S34) and ends the second frame member 2B. The part holding member drive mechanism 11 is retracted to the detached position Pd2 (process S35), and the holding member 10 and the first frame member 2A and the second frame member 2B held by the holding member 10 are slightly displaced to the outside of the frame body 1. The welded surfaces 3 (including the spread portions 31 and 32 of FIGS. 4 and 5) of the first frame material 2A and the second frame material 2B are separated from the surface of the corner heater plate 20, and the first frame material 2A and the cubic material are separated from each other. The welding surface 3 of No. 6 is separated from the surface of the intermediate heater plate 60 (process S36).

Further, the control device 7 retracts the corner heater plate drive mechanism 21 and the intermediate heater plate drive mechanism 62 to a predetermined retreat position (processes S37 and S38). At this point, the heating of the heater plates 20 and 60 (treatments S22 and S24) is stopped.
As a result, the heating step S3 is completed.

When the heating step S3 is completed, the control device 7 executes the crimping step S4.
In the crimping step S4, the end holding member driving mechanism 11 and the intermediate portion holding member driving mechanism 51 of the first frame material 2A are moved forward again (process S41), the first frame materials 2A are brought close to each other, and the second frame material is brought close to each other. The end holding member drive mechanism 11 of 2B is also advanced again (process S42), and the second frame members 2B are brought close to each other.
By bringing the first frame materials 2A close to each other, the welded surfaces 3 of the first frame material 2A and the second frame material 2B facing each other at the corners are crimped to each other, and the intermediate portion (V-shaped) of the first frame material 2A is pressed. Shape) and the welded surfaces 3 at the ends (triangular shape) of the cubic member 6 are crimped to each other (process S43).
Further, in the present embodiment, the second frame material 2B is also brought close to each other so that the welded surfaces 3 of the first frame material 2A and the second frame material 2B, which are crimped at the corners, are crimped at positions aligned with each other. Can be done.

As shown in FIG. 6, in the first frame material 2A, the welding surface 3 of the second frame material 2B is arranged to face the welding surface 3 at the end. Further, a triangular 3T of the cubic member 6 is introduced into the V-shaped 3V at the intermediate portion of the first frame member 2A, and the welding surfaces 3 are arranged to face each other.
These welded surfaces 3 are sufficiently heated in the heating step S3, and the molten resin required for welding is produced on the welded surface 3.
In this state, the first frame material 2A and the second frame material 2B are brought close to each other by the movement 11M in which the first frame material 2A of the above-mentioned processing S42 is brought close to each other and the second frame material 2B of the above-mentioned processing S43 are close to each other. Movement 12M is added.

As shown in FIG. 7, the first frame member 2A and the second frame member 2B advance from the detachment positions Pd1 and Pd2 in the processes S34 and S35 to the crimping positions Pc1 and Pc2 by the movements 11M and 12M, respectively.
The crimping positions Pc1 and Pc2 are the final positions, that is, the design positions of the first frame member 2A and the second frame member 2B in the mullion frame 1, respectively.
The detachment positions Pd1 and Pd2 are set to positions retracted from the crimping positions Pc1 and Pc2 by the amount that the first frame member 2A and the second frame member 2B move forward by the movements 11M and 12M, that is, the crimping allowance.

Therefore, in the crimping step S4 of the present embodiment, when the first frame material 2A and the second frame material 2B move and advance by the movements 11M and 12M, the welding surfaces 3 do not move relative to each other and are melted. The resins are crimped while remaining in the same relative position.
As shown in FIG. 8, the welded surfaces 3 (see FIGS. 4 and 5) of the first frame material 2A and the second frame material 2B melted in the heating step S3 by such a crimping operation are expanded to each other. The extension portion 31 and the extension portion 32 are pressure-bonded to each other to obtain welding of the base materials 4 to each other over a wide area, and the surface materials 5 on the extension portion 32 side are connected to each other.

Such a crimping state is due to advancing the crimping allowance (process S42 in FIG. 2) also for the second frame material 2B in the present embodiment.
If, in the crimping operation, the crimping allowance of the second frame material 2B is not advanced as in the conventional case, the following situation occurs.

In FIG. 9, the first frame member 2A and the second frame member 2B are arranged in substantially the same manner as in FIG. 6 described above.
However, as shown in FIG. 10, since the second frame member 2B does not move 12M (see FIGS. 6 and 7), it is already arranged at the crimping position Pc2 which is the final position before crimping. ..

In this state, as a crimping operation, when the first frame material 2A is moved forward by the movement 11M, the second frame material 2B does not move, and the welding surface 3 of the first frame material 2A is the welding surface of the second frame material 2B. It moves relative to 3 and produces a displacement of 13M.
As shown in FIG. 11, due to the occurrence of such a displacement 13M, the welded surface 3 of the first frame member 2A has the spread portion 32 (see FIGS. 4 and 5) of the welded surface of the second frame member 2B. It comes into contact in the middle of No. 3 and is dragged toward the spreading portion 31 side by the further displacement 13M. On the other hand, the welded surface 3 of the second frame material 2B is generally pushed out of the second frame material 2B by the first frame material 2A.

As a result, the welded portions of the first frame material 2A and the second frame material 2B are displaced from each other by the welding surface 3, and in particular, the spread portion 32 exposed to the outside of each frame material is not properly joined, and each of them is not properly joined. The surface material 5 of the above is also discontinuous, which may impair the appearance.
On the other hand, as shown in FIG. 8, according to the crimping of the present embodiment, the welded portion can be in a prepared state.

When the crimping step S4 is completed, the taking-out step S5 is executed.
In the take-out step S5, the operator divides all the holding members 10, 40, and 50, and takes out the integrated mullion frame 1.

According to this embodiment, there are the following effects.
In the present embodiment, by sequentially executing the preparation step S1, the heating step S3, the crimping step S4, and the taking-out step S5, the first frame material 2A, the second frame material 2B, and the mullion material 6 are welded together to form a mullion frame. 1 can be manufactured.

In the heating step S3, when the welded surface is heated, only the pair of first frame members 2A are moved inward in a rectangular frame shape (process S31), so that the cubic members 6 and the members joined to the first frame members 2A The same melting allowance can be moved to each of the pair of second frame members 2B.

In the crimping step S4, when the welding surfaces 3 of the first frame material 2A, the second frame material 2B, and the cubic material 6 are crimped to each other, the pair of the first frame material 2A and the pair of the second frame material 2B are respectively rectangular frame-shaped. By moving inward (movements 11M and 12M, see FIG. 7), the welding surface 3 of the first frame material 2A and the welding surface 3 of the second frame material 2B can be brought into the same moving state (FIG. 7). 8), it is possible to eliminate the relative movement of both welding surfaces 3 and arrange the welding marks.

Further, in the present embodiment, in the heating step S3, the first frame material 2A is brought close to each other while the welding surface 3 is heated by the corner heater plate 20 (inward in the rectangular frame shape of the mullion frame 1). When moving), the corner heater plate 20 is relatively moved inward in a rectangular frame shape with respect to the welding surface 3. By this relative movement, a part of the molten resin of the welding surface 3 in contact with the corner heater plate 20 can be guided inward in a rectangular frame shape together with the corner heater plate 20.

That is, in the description of the heating step S3, as described with reference to FIGS. 4 and 5, the welding surface 3 is extended outward with the mullion frame 1 due to the inward movement 10M of the first frame member 2A. The extension 31 is formed. Further, due to the inward movement 20M of the corner heater plate 20, the corner heater plate 20 and the welding surface 3 move relative to each other, and a part of the molten resin on the welding surface 3 is spread inward, so that the spread portion 32 is formed.
That is, it is possible to prevent the molten resin of the welding surface 3 from being excessively spread inside the first frame material 2A and the second frame material 2B.

In the present embodiment, the frame material 2 in which the surface material 5 is stretched on the base material 4 is used, but the surface material 5 melted on the welded surface 3 is exclusively directed to the inwardly extending portion 32 side of the mullion-mounted frame 1. Can be induced. As a result, it is possible to prevent the surface material 5 from entering the spread portion 31, and it is possible to ensure welding of the base materials 4 to each other in the spread portion 31.

The present invention is not limited to the above-described embodiment, and modifications and the like within the range in which the object of the present invention can be achieved are included in the present invention.
For example, in the above-described embodiment, when heating the welding surface 3, in the heating step S3, continuous movement from the initial stage of heating to the heating end position Ph1 of the holding member 10 of the first frame member 2A is started, but heating is performed. Preheating may be performed by temporarily stopping at the contact position Ps1. For example, the holding members 10 of the first frame material 2A and the second frame material 2B are advanced to predetermined heating contact positions Ps1 and Ps2, respectively, and stopped at these positions to form the first frame material 2A and the second frame material 2B. A preheating step (corresponding to treatments S21 to S28) in which the welding surfaces 3 are in surface contact with the surfaces of the heater plates 20 and 60, and each welding surface 3 is heated to a predetermined depth from the surface, and the above-mentioned preliminary When the preheating in the heating step is started and a predetermined time elapses, both of the main heating step in which the above-described processes S31 to S38 are performed may be performed as the heating step S3 by a command from the control device 7.

In the above-described embodiment, the operator carries in the frame material 2 (first frame material 2A, second frame material 2B) and the mullion 6 to the manufacturing apparatus 9, and takes out the integrated mullion frame 1 from the manufacturing apparatus 9. However, an automatic transfer device or the like may be combined.
In the above-described embodiment, each step is progressed by the control device 7, but at this time, not only the progress control based on the passage of a predetermined time but also the temperature rise of the welding surface 3 due to heating is measured and confirmed. Then, control may be performed so as to proceed to the next step.

In the above-described embodiment, as the frame material 2 and the cubic material 6, the base material 4 is covered with the surface material 5, but the frame material 2 having only the base material 4 without the surface material 5 may be used.

The present invention can be used as a method for manufacturing a frame with a mullion and a device for manufacturing a frame with a mullion. A frame material made of a thermoplastic resin and a mullion are arranged in a rectangular frame shape, and their ends are welded to each other. It can be used for manufacturing a frame with a mullion to be used as a frame with a mullion.
