The present invention relates to an apparatus for manufacturing an insulating bonded structure used for a window frame or a door frame, and, as described above, is provided with two grooves arranged so as to form a groove and a cross-linking portion having an open side therebetween at a distance from each other. In order to manufacture insulating bonded structural materials for window frames or door frames, which are composed of metal structures made of metal and whose thermal insulation is formed by injecting synthetic resins with poor thermal conductivity into the grooves, the expectation of the workbench supporting the metal structural materials ( Conveying and guiding means for conveying the substrate and the metal structural material under the injection means.

Such a device known by German Patent Publication No. 2160253 was used to fill a groove between two metal structural members having a crosslinking portion with a curable injection resin so as to fill the front end face of the groove. By the way, in the case of the metal structural material which is long in a longitudinal direction, manufacture of the defect structural material which has the partial insulation core vertically arrange | positioned up and down in the groove | channel separated from each other by some hollow part filled with the heat insulating material depending on the case is impossible with a well-known apparatus. And it did not appear again.

It is an object of the present invention to firstly provide an apparatus capable of producing a simple and economically insulative defect structural material having two or more insulation cores arranged up and down at intervals and separated from each other by a hollow part, The object is that, in the above known device, another intermediate cross-linking part is arranged between the two injection means arranged next to each other and placed one or more injection means next to the injection means in the conveying direction, separating plate or similar means. Insert into the groove above it with proper distance from the bridge underneath

Another object of the present invention is to broaden the scope so that the hollow part can also manufacture the bonded structural material as a heat insulating material without further disturbing the continuous working process in the application of the above apparatus, and the apparatus of the present invention is In the insulating bonded structure, additionally, the hollow part filled with the insulating material can bring about the improvement of the heat insulating action on the other hand if the strength of the structural material as a whole is strengthened on the one hand.

In order to achieve this effect, a resin material, such as a reaction mixture of foamed synthetic resin, is placed between the metal structural material, after the first injection means in front of the first injection means, in front of the insertion position of a separator or similar means. There is a need to provide a second injection means for injection into the hollow portion of the. This second injection means is preferably connected with a control means for metering the discharge amount of the heat insulating material for effective heat insulation action.

The device according to the present invention has a simple structure and satisfies various preconditions for economically manufacturing the bonded structural material in the manufacturing process, so that the groove portions in the same bonded structural material are continuously formed to form a thermal insulation core at intervals from each other. At the same time, the process can be filled with adiabatic injection material. By providing such injection means and cutting means according to the present invention, the overall length of the manufacturing process, and therefore the site area in the manufacturing plant can be greatly reduced. Where the liver between each two injection means arranged side by side

In yet another advantageous embodiment of the invention, the means for inserting the separator comprises one or more separator winding winding rollers which are supported on the shaft and capable of unwinding the separator in the conveying direction together with the conveying speed of the metallic structural material. do. The separating plate winding storage rollers are preferably arranged immediately after the first injection means for filling the groove portions in the lower side, respectively, in the direction of conveyance of the structural material. In this case, it is possible to shorten the pre-casting time of each bonded structural member directly following in the manufacturing process.

The separator winding storage roller is arranged above the groove, and it is advantageous that the axis on which the separator winding storage roller is placed extends transversely with respect to the conveying direction of the metal structural material.

According to an example of embodiment of the present invention, the drive of the separator winding storage roller is mechanically derived from the drive device of the transfer means of the metallic structural material and simultaneously driven together with the drive device of the transfer means.

In accordance with another preferred embodiment of the device according to the invention, the front ends of the separator plates are transported from one another to the front ends of the metal structural continuum moving under the injection means in such a way that they are attached by hooks or tapes. It is unwound from the winding storage roller separated according to the movement. According to this embodiment, the special driving means by driving the separator winding storage roller can be omitted.

One or more separator pressing rollers or similar means are provided after each separator winding storage roller in the direction of conveyance of the structural member to assist insertion of the separator into the grooves. This separator press roller is supported by a swinging arm loaded by a spring or weight and presses onto a protrusion for supporting the separator. It is preferable that a separating plate guiding means consisting of the guiding roller and the guiding plate is provided after the separating plate winding storage roller.

Next, the apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

The device shown is for use in the manufacture of the joining structure 1 (see FIGS. 3 and 14). Each joining structure consists of two metals (2) and (3) arranged at regular intervals from each other, which form an open groove (4) extending therebetween, extending over the entire length therebetween. In the example shown also inside the structural material, it is divided into two groove parts 5 and 6 formed up and down. However, this groove portion can form a large number of groove portions in other embodiments. Under the lower groove portion 5, there is a crosslinked portion 7 made of metal represented by a dotted line, and the crosslinked portion 7 connects the two metal structural members 2, 3 to each other. The bridge | crosslinking part 7 integrally formed with these metal structural materials is cut | disconnected between these metal structural materials later.

The joining structure also has a separator plate 8, which is placed on top of the support protrusion 9 which extends over the entire length of the metal structure material thereon at a uniform distance from the bottom bridge 7. The lower groove portion 5 is filled with the insulated material to be injected, and the insulated material forms the lower partial insulation core 10 after curing, and the lower partial insulation core joins both metal structural materials in the lower portion.

The upper groove portion 6 has an upper portion heat insulation core 11 which forms another bond between the two metal structures. Between the partial insulation cores 10, 11 there is a hollow portion 12 (see FIG. 3) which is not filled with the injection material extending over the entire length of the joining structure, which is shown in FIG. In the case of the example, it can be filled with a heat insulating material, preferably foamed synthetic resin 112, which not only improves the heat insulation action, but also strengthens the strength as a whole of the bonded structural material. Of metal structural materials (2), (3) and partially insulating cores (10), (11)

The coupling structure shown in FIG. 3 and FIG. 14 can be changed into arbitrary shapes different from the coupling structure material 1 mentioned above, for example as shown to the cross section in FIGS. 4-9 and FIG.

The apparatus for producing such a joining structure includes, for example, one or more horizontally arranged work benches 15 (see also first, second, twelve and thirteenth), which work platform is based on the crust 16. It is supported above. The workbench has a mounting surface on which metal structures (2) and (3) are placed, and these metal structures are placed between the rollers (18) and (19) in the direction of the arrow (17) on a predetermined track while being machined into a joining structure. Transferred. The rollers 18 and 19 are supported on the vertical shafts 18 'and 19' attached to the work bench 15.

One of the rollers 18 on the workbench is fixed on the vertical axis 18 'and driven by the vertical axis 18', but the rollers 19 arranged on the other side are not driven and are only driven by the roller 18 driven. According to the metal structure member (2), followed by (3) is pressed to act as a pressing roller. The motor 20 is used as a driving source of the roller 18, and the driving gear 21 drives the horizontal shaft 23 through the gear 22. The horizontal axis 23 has a bevel gear 24 at regular intervals from the roller 18 in the longitudinal direction, which meshes with a corresponding bevel gear 25. The bevel gear 25 is mounted on the vertical axis 18 'protruding below the work table, and transmits the driving operation transmitted from the motor to the roller 18.

The first injection means 26 (see FIG. 2 and FIG. 4) is provided on the work table, which is constituted by the injection head 27 and the discharge nozzle 28. As shown in FIG. The injection head 27 is connected to the injection material reservoir 30 via a conduit 29 and is mounted to the holder 31 so that the position can be adjusted and the holder is fixed to the work table 15. As the injection material, a well-known injection resin is used, which is discharged from the discharge nozzle 28 of the first injection means 26 in a flow state and cured in a short time. The injection material is supplied by a pump (not shown).

Second injection means 32 (first, second and eighth) with a slight spacing after the first injection means 26 in the conveying direction 17 of the metal structural members 2 and 3. ), Which has the same structure as the first injection means 26. In the case of the second injection means 32, the injection head and the discharge nozzle are represented by 33 and 34, respectively, and the connecting conduit is 35, the reservoir is 36, and the holder is 37 Is displayed. A separating plate winding storage roller 38 for storing the separating plate 8 is arranged between both injection means, ie after the first injection means 26 (see FIGS. 1, 2 and 5). When the metal structural member moves forward, the separating plate is continuously sent into the groove (4) from the position prepared in advance. Coils 8 'arranged at regular intervals above the grooves are supported on a horizontal axis 39 which extends transversely with respect to the conveying direction 17, which horizontal bearings 40, 41 allow free rotation. It is supported in the inside, and is supported on the work bench 15 by the support means 42.

The separator plate guide means 49 is followed by the separator plate winding storage roller 38, which is separated by the guide roller 50 and the guide plate 51 which is convexly curved (see FIG. 6). The plate is temporarily bent in the transverse direction so that the separator plate is easily placed on the protrusion 9 in the groove. In particular, the use of the guide plate 51 is useful when the width of the separating plate is larger than the inner dimension of the groove determined by the mutual spacing of the projections 13 (see FIGS. 3 and 14).

The conveying direction of the separating plate winding storage roller 38 and the separating plate guide means 49 is also followed by a pressing roller 44 (first, second, and seventh), which is freely supported on the swinging arm 43. This press roller presses the separator plate 8 onto the support protrusions 9 so that the separator plate is placed on these protrusions, which may be necessary in some specific cases depending on the nature of the separator plate. The pivot arm 43 is supported on the shaft 45 at the end opposite to the press roller, which is supported at both ends in the bearing 46, which is loaded by the support means 42, the shaft being bearing at both ends. 46 is fixed to the workbench by means of the support means 42. The turning arm 43 is loaded by a spring or weight in order to give the necessary pressure to the separating plate 8, which is not shown in detail in the drawings.

In still another aspect of the apparatus described above, in the case of the example shown in FIGS. 12 and 13, after the first injection means 26, just before the separating plate winding storage roller 38, the second injection A means 126 is provided, which has the same configuration as the first injection means 26 and has an injection head 127 and a discharge nozzle 128. Conduits leading to the injection material reservoir are indicated at 129 and holders at 131. As the injection material to be injected into this injection device, a particularly known reactive mixture of polyurethane foamed synthetic resin is used, which is a plastic phase.

Next, operation of the apparatus according to the present invention will be described.

Both metal structures (2) and (3) connected by the lower crosslinking portion (7) of long continuous bodies which are sent out through the manufacturing process without being separated back and forth are shown in FIGS. 1, 2, and 12 And guided between the rollers 18 and 19 as an integral unit, as shown in FIG. 13, and these rollers are adapted to mutually adjust their horizontal spacing so as to be suitable for metal structures having different widths. .

As described above, in the illustrated example, the rollers 18 are driven so that these structuring agents are conveyed in the direction of the arrow 17. When these structural materials pass through the injection head 27, the injection material continuously flows from the top into the groove 4 which is open from the top and the bottom is blocked by the bridge 7 (see FIG. 4). do. The conveying speed of the metallic structural material is precisely matched with the outflow rate and the discharge amount of the injected material, thereby causing the injected material to reach a constant level almost similar to the height of the projection 14 'over the entire length of the metallic structure.

When the front ends of the individual metal structural members 2, 3 reach the injection head 126 (see Figs. 12 and 13), the injection material continues continuously as in the first injection means 26. Moreover, it flows into the hollow part 12 (refer FIG. 15) uniformly. However, the hollow part 12 is filled below the support protrusion 9 at a predetermined interval or only up to a certain height, thereby preventing the subsequent insertion of the separator plate. The front end portion 48 of the metal structural members 2, 3, which is continuously sent out during the entire machining process, follows the first injection means 26.

When the injection material is ejected from the front end portion 48 of the groove 4 between the manufacturing processes, it is prevented by blocking it with an adhesive tape or the like, for example. In continuous operation, it is unnecessary to block the ends of individual structural members in this way, and the grooves 4 of each structural member that are continued back and forth because the front and rear ends of each structural member directly touch the corresponding ends of the front and rear structural members are not necessary because they continue without interruption. Do. In the connection of structural members, it is only necessary to cover the first and last structural members with adhesive tape. This work process is only once at the start of the operation blocking the front end of the first structural material to be filled with the injection resin and also at the end of the operation blocking the open rear end of the last structural material. The continuous grooves without interruption through all the structural material going back and forth allow continuous injection of the insulating material of the structural material, so that no air space in the thermal insulation material formed by shrinkage of the material at the end of the structural material occurs.

In the above-described manner, the structural member filled with the injection resin in two planes arranged up and down is continuously transferred forward at the same speed on the work bench after passing through the last injection device. The front end of the structural member reaches the cutting means (see FIGS. 1 and 12) when the heat insulating material finally filled in the groove 6 (upper side) is cured. This cutting means is an extension part 15 'of the work bench 15, and its mounting surface is bent at an angle with respect to the symbol 15. As a result, the preceding structural members 2 'and 3' are no longer supported by the workbench,

Of course, instead of the extension part 15 'as described above, the continuous structural member continuum may be cut at each joint by a suitable saw 55 as shown, for example, by dashed lines in FIGS. 1 and 12. The saw can be arranged to move not only in the conveying direction (arrow 57) and its reverse direction, but also in the right angle direction (arrow 58) so that it can be operated without interrupting the conveying. Similarly, for example, a method of cutting by a human hand, or by a scissors, a knife, or the like can be considered.

Another cutting device 59 is shown in FIGS. 10 and 11. This is directly following the end of the work bench 15 and is arranged in front of the conveying direction 17 of the extension 15 'or 55 described above as one of the features of the present invention. The cutting device 59 removes the bridge | crosslinking part 7 between the metal structural materials 2 and 3, and serves to prevent thermal conduction by a metal. This includes a saw 60, cutter or similar means which are arranged above the extension 15 'of the work bench 15. The saw 60 is positioned on the output shaft 61 of the motor 62.

The roller 64 shown in FIG. 9 can adjust the height in the direction of the arrow 65, and serves as a lag in the vertical direction with respect to the metal structural members 2 and 3. As shown in FIG. The metal structural materials 2 and 3 are wool rollers 18 in this part. By (19) as described above. The drive motor 20 '(see FIG. 10) corresponds to the motor 20 of FIG.

The roller 64, which is freely rotatable in the bearing 66, is fixed to the frame portions 67 and 68 of the base 15 ". In the arrangement of the saw 60, this is the injection means. At a sufficient interval after (32), that is, until the insulating material is finally filled in the grooves until it reaches this saw position, it achieves sufficient shape stability before reaching the saw, in other words After (3) and (3) have removed the crosslinking portion 7, it is necessary to arrange them at sufficient intervals to avoid the possibility of displacing them from each other due to incorrect curing of the insulating material.

As described above, the manufacture of the bonded structural material is a manufacturing process from the time when the structural material is fed in front of the first injection means of the apparatus according to the present invention to the end of the extension part 15 'and the cutting device 55. It can be produced continuously without interruption.

Of course, instead of removing the crosslinked portion 7 from the metal structural member in advance as in the case of FIG. 10, it may be detached from the back of the extension 15 'and the cutting device 55 as shown in FIG. However, this may adversely affect the low friction manufacturing process.

If the insulation core requires a bonded structural material divided into two or more partial insulation cores as described above, for each additional partial insulation core, at least one or more separator winding storage rollers 38 and another injection means are employed. It is only necessary to place the unit after the second injection means 32, which units may each be combined with an additional third injection means 126, and each press roller and / or separator plate guide means, if necessary. Can be formed. As apparent from the foregoing, the device may be

Feeding of the separating plate 8 is made by the conveying motion of the metal structure continuous body as mentioned above. To do this, it is only necessary to attach the free end of the separator 8 to the front end of the original structural member only once, for example using adhesive tape, at the start of a series of operations or when a new separator winding winding roller is changed. The adhesive force on the separating plate is transferred by curing the injection material in the preceding structural member 2 ', (3) or (2), (3) (see FIGS. 1, 2, 12 and 13). It is sufficient to unwind the separator without using additional drive means from the separator winding storage roller 38 between movements. It is obvious that other suitable fastening means may of course be chosen instead of the adhesive tape, and for example, although not shown, a hook may be used so that it hangs on the front ends of the first structural members 2 ', 3.

In addition, the injection process of each of the injection devices 26, 32, 126 may be automatically started by a photo device or other suitable means not shown. Instead of the injection resin injected into the liquid phase as described above, the insulating material may be directly extruded into the groove.

As mentioned above, although this invention demonstrated the integral metal structural material connected by the bridge | crosslinking part 7, of course, the bridge | crosslinking isolate | separated from these instead of the bridge | crosslinking part 7 integrated using the metal structure agent separated from each other from the beginning. You can also use wealth. In this case, the cutting device 59 can be omitted.

The rollers 54 supported by the gap members 52 and 53 as shown in FIG. 2 serve to guide the metal structural members 2 and 3 from above, which is the height of the metal structural member at that time. Depending on the height can be mounted so that the position can be adjusted.
