  Then, when stacking a plurality of combination materials A in which two metal foils 1, 1 and one insulating adhesive film 2 are stacked using the stacking apparatus as described above, the following is performed.

  First, the lower metal foil 1 is pulled out from the roll 3 and held and set in the material setting machine 30. At this time, in order to secure a work space, the winder 5 is preferably arranged vertically (see FIG. 5A). As shown in FIG. 6A, the metal foil 1 is set by placing the metal foil 1 pulled out from the roll 3 so as to exceed the upper side of the holding bar 31 attached to the material setting machine 30, As shown in FIG. 6B, the tip of the metal foil 1 is disposed between the clamping pieces 44a and 44a of the lowermost clamp members 44 and 44 and the material holding surface 42, and the clamping pieces 44a and 44a. By moving the clamp members 44, 44 so as to approach the material holding surface 42, both end portions of the metal foil 1 are interposed between the sandwiching pieces 44a, 44a and the material holding surface 42 as shown in FIG. Clamp the part. Here, the height position of the elevating body 41 of the material setting machine 30 is a roll replacement height position H1. Further, the metal foil 1 set in the material setting machine 30 is disposed in contact with the upper surface of the holding bar 31, and the clamping pieces 44a, 44a of the uppermost and middle clamp members 44, 44 and the material holding surface 42 are disposed. It is arranged so as to pass between.

  Next, the insulating adhesive film 2 is pulled out from the roll 4 arranged between the upper and lower metal foils 1, 1 and held and set in the material setting machine 30. At this time, the insulating adhesive film 2 is set by disposing the insulating adhesive film 2 drawn from the roll 4 so as to exceed the upper side of the metal foil 1 set in the material setting machine 30, and Is disposed between the clamping piece 44a, 44a of the middle clamping member 44, 44 and the material holding surface 42, and the clamping member 44, 44 is moved so that the clamping piece 44a, 44a approaches the material holding surface 42. 6 (d), the both end portions of the insulating adhesive film 2 and the both end portions of the set metal foil 1 are clamped (clamped) between the holding pieces 44a, 44a and the material holding surface 42. ) Here, the height position of the elevating body 41 of the material setting machine 30 is the same roll replacement height position H1 as described above. Further, the insulating adhesive film 2 is disposed in contact with the upper surface of the metal foil 1 set in the material setting machine 30, and the clamping pieces 44a and 44a of the uppermost clamp members 44 and 44 and the material holding surface 42 are disposed. It is arranged so as to pass between.

  Next, the upper metal foil 1 is pulled out from the roll 3 and held and set in the material setting machine 30. At this time, the metal foil 1 is set by placing the metal foil 1 drawn out from the roll 3 so as to exceed the upper side of the insulating adhesive film 2 set in the material setting machine 30, It arrange | positions between the clamping piece 44a, 44a of the uppermost clamp members 44 and 44, and the material holding surface 42, and this clamping piece 44a, 44a approaches the material holding surface 42, as shown in FIG.6 (e). By moving the clamp members 44 and 44 in such a manner, the both end portions of the metal foil 1 and the both end portions of the insulating adhesive film 2 are set between the sandwiching pieces 44 a and 44 a and the material holding surface 42. The both end portions of the metal foil 1 are clamped (clamped). Here, the height position of the elevating body 41 of the material setting machine 30 is the same roll replacement height position H1 as described above. The metal foil 1 set on the material setting machine 30 is disposed in contact with the upper surface of the insulating adhesive film 2 set on the material setting machine 30.

  Through the above operation, as shown in FIG. 7, the two metal foils 1, 1 and the one insulating adhesive film 2 are sequentially stacked on the upper surface of the holding bar 31, and then the fixing cover 48 and the lock member are stacked. The metal foils 1, 1 and the insulating adhesive film 2 are fixed and set to the holding bar 31 by a pressing tool 35 composed of 49. That is, as shown in FIGS. 8A and 8B, the fixed cover 48 formed in a substantially C-shaped cross section with a metal plate or plastic is elastically applied to the holding bar 31 from the surface side of the outermost metal foil 1. The metal foils 1 and 1 and the insulating adhesive film 2 are sandwiched between the fixed cover 48 and the holding bar 31 over the entire length in the width direction, and as shown in FIG. The fixed cover 48 is fixed to the holding bar 31 by sandwiching both end portions 48a of the 48 and the holding bar 31 with a lock member 49 such as a clip. At this time, the slit 33 of the holding bar 31 is positioned immediately below the edge of the fixed cover 48 on the winder 5 side.

  Next, the metal foils 1 and 1 and the insulating adhesive film 2 that are held and set on the holding bar 31 are cut. As shown in FIG. 9, the cutting is performed by inserting the cutter (blade) 32 from the surface of the outermost metal foil 1 and inserting the cutter 32 into the slit 33 in the longitudinal direction of the slit 33. Move along. Further, at the time of cutting, a hose 51 is connected to the end opening of the holding bar 31 and air is sucked into the inner space of the holding bar 31 through the hose 51 by the vacuum pump 50 or the like. And dust generated by the cutting of the insulating adhesive film 2 can be sucked and removed from the slit 33 which is the suction port 34, and the dust does not adhere to the metal foil 1 or the insulating adhesive film 2 so It is possible to prevent a molding defect from occurring in the laminated board B. In this example, the slit 33 and the suction port 34 are used together, but the suction port 34 may be formed in the holding bar 31 separately from the slit 33. Then, by this cutting, a part of the metal foil 1 and the insulating adhesive film 2 positioned at the lower end position H0 lower than the holding bar 31 is excised, and the front end portion of the cut metal foil 1 and the cut post-cut portion The metal foils 1, 1 and the insulating adhesive film 2 can be positioned on each other in the width direction and laminated on the surface of the holding bar 31 in a state where the front end portion of the insulating adhesive film 2 is aligned, A pair of combination material A can be formed by overlapping the insulating adhesive film 2 between the foils 1 and 1.

  Thereafter, the winder 5 is rotated so as to be horizontally arranged so that the attaching / detaching position of the holding bar 31 is close to the material setting machine 30 (see FIG. 5A), and insulated from the metal foils 1 and 1. The holding bar 31 is removed from the lifting body 41 of the material setting machine 30 while holding the adhesive film 2, and the holding bar 31 is carried to the winder 5 supported by the bearing 61. The horizontal frame member 59 is coupled to the vertical frame members 58 and 58. In this way, the front end of the combination material A can be held at one place on the outer surface of the winder 5. Next, by rotating the winder 5 in one direction, the metal foil 1 is unwound from the roll 3 and the insulating adhesive film 2 is unrolled from the roll 4 to wind the combination material A around the winder 5. it can. The combination material A in which the insulating adhesive film 2 is overlapped between the two metal foils 1 and 1 is wound up in a state of being stacked in multiple layers on the outer surface of the winder 5. In the case of being formed of a flat body, the combination material A can be stacked on both surfaces of the winder 5 in a state of being folded at both ends of the winder 5 (between the outer sides of the horizontal frame bodies 59, 59). Is. In order to prevent the metal foil 1 and the insulating adhesive film 2 from hitting the material setting machine 30 when the combination material A is wound by the winder 5, the elevating body 41 is located at the lower end position below the roll replacement height position H1. It is moved so that it is located at H0.

  In this way, when the winder 5 is driven to rotate so that the metal foil 1 and the insulating adhesive film 2 are pulled out from the rolls 3 and 4 and wound around the winder 5, the brake mechanism 62 is rotated to rotate the rolls 3 and 4. When braking is applied, the rolls 3 and 4 do not rotate with inertia at a speed faster than the speed at which the metal foil 1 and the insulating adhesive film 2 are taken along with the rotation of the winder 5. 1 and the insulating adhesive film 2 can be wound around the winder 5 with tension applied thereto, and the metal foil 1 and the insulating adhesive film 2 can be wound around the winder 5 without generating wrinkles. It can be done.

  The operation as described above is preferably performed in a state in which the ventilation means 8 is operated to reduce the foreign matter inside the apparatus main body 6 and clean it.

  If the metal foil 1 or the insulating adhesive film 2 is wound around the winder 5 in this way and the winding is completed without the amount of foreign matter detected by the foreign matter detecting means 9 reaching a predetermined amount, the combination material A Is removed from the winder 5. In this case, as shown in FIG. 10A, the combination material A is wound in a flat spiral shape, and the combination material A in which the insulating adhesive film 2 is overlapped between the two metal foils 1 and 1. Are stacked in large numbers up and down.

  Here, when removing the winder 5 from the spiral combination material A, it is possible to disassemble the winder 5 by removing the connection between the horizontal frame body 59 and the vertical frame body 58, At this time, the holding member 35 can be detached from the holding bar 31 that is the horizontal frame member 59 to release the holding of the combination material A from the holding bar 31. Further, the combination material A is placed on the carrier plate 53 together with the winder 5, and the horizontal frame body 59 and the vertical frame body 58 are disconnected and disassembled to disassemble the horizontal frame body from the spiral combination material A. 59 can also be removed. In this case, the winder 5 can be easily removed from the spirally wound combination material A.

  Then, the combination material A stacked as described above is sandwiched between the carrier plate 53 formed of a metal plate and the plate 55 as shown in FIG. 10B (if necessary, the carrier plate 53 and the plate 55 A plurality of sets of combination materials A may be sandwiched between them), and by setting this between the heating plates 54, 54, it is possible to perform heat and pressure molding, and both surfaces of the insulating adhesive film 2 A double-sided metal foil-clad laminate B in which metal foils 1 and 1 are laminated can be formed. The laminated board B obtained by molding in this way has a flat spiral shape, but by cutting the bent portion (the cut portion is indicated by a chain line in FIG. 10 (b)), a flat double-sided metal The foil-clad laminate B can be obtained.

  Further, when using the flat plate-shaped winder 5, it does not hinder the combination material A from being heated and pressed, so that the combination material A is wound around the winder 5 in a flat spiral shape. Sandwiched between the carrier plate 53 and the plate 55 (if necessary, a plurality of sets of combination materials A may be sandwiched between the carrier plate 53 and the plate 55). The double-sided metal foil-clad laminate B in which the metal foils 1 and 1 are laminated on both sides of the insulating adhesive film 2 may be formed by performing heat and pressure molding.

  Further, while the metal foil 1 or the insulating adhesive film 2 is being wound around the winder 5 as described above, the foreign matter detected by the foreign matter detecting means 9 due to the deterioration of the atmosphere around the apparatus body 6 When the amount reaches the predetermined amount, the control unit 11 activates the notification unit 10 to notify the operator, the manager, or the like that the atmosphere around the apparatus body 6 has deteriorated. it can. For this reason, an operator or an administrator operates the apparatus main body 6 to stop the work until the atmosphere around the apparatus main body 6 is improved, take measures for improving the atmosphere, or manage the work state. can do.

  Further, when the amount of foreign matter detected by the foreign matter detection means 9 reaches a predetermined amount as described above, the rotational drive of the winder 5 may be stopped by automatic control by the control means 11. In this case, it is possible to prevent the metal foil 1 and the insulating adhesive film 2 from being wound in a state where the surrounding atmosphere is bad, and to prevent the winding from being performed in a state where foreign matter is mixed.

  When the winder 5 is stopped in this manner, it is preferable to stop the winder 5 in a state in which foreign matter hardly enters between the winder 5 and the metal foil 1 or the insulating adhesive film 2, that is, the insulating adhesive film 2. It is preferable that the winder 5 is not disposed below the portion of the metal foil 1 that is stretched between the rolls 3 and 4 and the winder 5. For this purpose, the surface facing upward of the winder 5 and the insulating adhesive film 2 disposed between the upper roll 3 and the winder 5 are aligned in a straight line, It is desirable to stop the winder 5 between the state in which the winder 5 is arranged vertically (see FIG. 5B).

  Further, after the rotation of the winder 5 is stopped in this way, if the amount of foreign matter detected by the foreign matter detecting means 9 falls below a predetermined amount, the winding is performed by automatic control by the control means 11. The tool 5 may be rotated again to resume the winding of the metal foil 1 or the insulating adhesive film 2. As a result, the winding can be resumed in a state where the atmosphere of the apparatus main body 6 is improved, and the winding can be performed so that no foreign matter is mixed therein.

  Further, when the amount of foreign matter detected by the foreign matter detection means 9 reaches a predetermined amount, the ventilation amount by the ventilation means 8 may be increased by the control means 11 by automatic control. For example, when using the fan 8b as the ventilation means 8 as in this embodiment, the ventilation means 8 is rotated at a normal rotational speed (for example, 40 Hz) in a state where the amount of foreign matter detected by the foreign matter detection means 9 does not reach a predetermined amount. When it is detected that the amount of foreign matter exceeds a predetermined amount, the ventilation rate is increased by increasing the rotational speed of the fan 8b (for example, 60 Hz), and the amount of foreign matter around the device body 6 is rapidly reduced. It is something to be made. In this way, the amount of foreign matter around the apparatus main body 6 can be reduced in a short time and the work can be resumed, and the work efficiency can be improved. When the amount of foreign matter detected by the foreign matter detection means 9 becomes less than a predetermined value after increasing the ventilation amount, the control means 11 automatically reduces the ventilation amount by the ventilation means 8 to reduce the normal amount. You may make it return to.

  Further, when the amount of foreign matter detected by the foreign matter detection means 9 reaches a predetermined amount, after the rotational drive of the winder 5 is stopped by automatic control by the control means 11, the insulating adhesive film 2 is cut by the cutting means 12. And the metal foil 1 may be cut between the rolls 3 and 4 and the winder 5. If it does in this way, when the atmosphere around the apparatus main body 6 deteriorates, winding-up of the insulating adhesive film 2 and the metal foil 1 will be stopped, and the winder 5 which wound up the insulating adhesive film 2 and the metal foil 1 will be removed. When the atmosphere around the apparatus main body 6 is improved, the winder 5 is driven to rotate and the insulating adhesive film 2 and the metal foil 1 are newly wound. it can.

  Any suitable cutting means 12 can be used, but in this embodiment, the material setting machine 30 is used as the cutting means 12 as described above. The operation in this case will be described.

  First, when the amount of foreign matter detected by the foreign matter detection means 9 reaches a predetermined amount, the rotational drive of the winder 5 is stopped by automatic control by the control means 11. The stopping position of the winder 5 at this time is preferably such that foreign matter is unlikely to enter between the winder 5 and the metal foil 1 or the insulating adhesive film 2 as described above. Considering workability when replacing the take-up tool 5, it is preferable to stop the take-up tool 5 in a state where it is inclined in the range of 20 ° to 25 ° with respect to the horizontal direction (see FIG. 5A).

  After the rotation of the winder 5 is thus stopped, the elevating body 41 to which the holding bar 31 is attached is raised, and the metal foils 1, 1 spanned between the winder 5 and the rolls 3, 4. By slightly pressing the insulating adhesive film 2 from the lower side with the holding bar 31, the metal foils 1, 1 and the insulating adhesive film 2 are superimposed on the surface of the holding bar 31. At this time, the elevating body 41 is moved up to the winder replacement height position H2 above the roll replacement height position H1, and the holding bar 31 is brought into contact with the metal foils 1, 1 and the insulating adhesive film 2. On top of the surface. The ascending / descending body 41 can be raised by the automatic control by the control means 11 in the material setting machine 30 (see FIG. 5A).

  Next, in the same manner as described above, the metal foils 1 and 1 and the insulating adhesive film 2 are fixed and set to the holding bar 31 by the presser 35 including the fixed cover 48 and the lock member 49. Next, in the same manner as described above, the metal foils 1 and 1 and the insulating adhesive film 2 which are set while being held by the holding bar 31 while being sucked are cut. And by this cutting | disconnection, the metal foil 1 and the insulating adhesive film 2 by the side of the winding tool 5 rather than the holding bar 31 and the metal foil 1 and the insulating adhesive film 2 by the side of the roll 3 and 4 from the holding bar 31 are separated. The

  Next, after removing the winder 5 that has wound the combination material A from the bearing 61, another new winder 5 is attached to the bearing 61. Next, the holding bar 31 is removed from the lifting body 41 of the material setting machine 30 while holding the metal foils 1, 1 and the insulating adhesive film 2, and the holding bar 31 is attached to the winder 5 supported by the bearing 61. To the vertical frame members 58 and 58 as one horizontal frame member 59 of the winder 5. Thus, after holding the front-end | tip of the combination material A in one place on the outer surface of the winder 5, the winder 5 is rotationally driven in one direction in the same manner as described above, so that the metal foil 1 is rolled. Then, the insulating adhesive film 2 is respectively unwound from the roll 4 so that the combination material A is wound around the winder 5. In order to prevent the metal foil 1 or the insulating adhesive film 2 from hitting the material setting machine 30 when the combination material A is wound by the winder 5, the lower end position below the roll replacement height position H1 of the elevating body 41 is changed. It is the same as that described above to move to H0.

  In the above description, the lamination of the two metal foils 1 and 1 and the insulating adhesive film 2 has been described. However, the present invention is not limited to this, and the present invention is not limited to this. It can also be applied to the lamination of. For example, by disposing a plurality of rolls 4 wound with an insulating adhesive film 2 between a pair of rolls 3 wound with a metal foil 1, a plurality of insulating adhesive films 2 between the two metal foils 1, 1. It is also possible to form the combination material A so as to be sandwiched between them. One of the pair of rolls 3 may be one in which a release film such as a PPS film or a fluororesin film is wound instead of the metal foil 1. Further, when the insulating adhesive film 2 is formed by bonding only one side and the other side being a non-adhesive surface, one roll 3 wound with the metal foil 1 and one roll wound with the insulating adhesive film 2 are used. The roll 4 may be used in combination, and the metal foil 1 may be wound around the winder 5 as a combination material A in which the insulating adhesive film 2 is overlapped on the adhesive surface.
