Description

  The present invention relates to a material supply apparatus and a laminate manufacturing apparatus using the material supply apparatus.

  Conventionally, as a laminated plate manufacturing apparatus, a plurality of rolls each wound with a plurality of sheet materials and a plurality of sheet materials unwound from the plurality of rolls are laminated and thermally bonded to each other while being passed in a laminated state. And a product winding device that winds the laminated plate from the hot pressing machine (see, for example, Patent Document 1).

  For this reason, in a material supply apparatus for supplying a plurality of sheet materials to a heat press machine, at least the number of roll support portions for supporting each roll is required, so that the plurality of roll support portions do not interfere with each other. Therefore, the material supply device is increased in size.

If a plurality of roll support portions are arranged without increasing the size of the material supply device, the plurality of roll support portions are close to each other. Work to insert into the press becomes difficult.
JP-A-5-42555 Japanese Patent Laid-Open No. 9-1590

  Therefore, the present applicant forms a roll by winding it in a roll state in a state in which a plurality of sheet materials are laminated, and the laminated roll is mounted on the laminated roll support part. I came up with a way to pull out.

  According to this method, since a plurality of roll support portions can be combined as one laminated roll support portion, the apparatus can be greatly reduced in size. However, when the sheet material is unwound from such a laminating roll, the amount of unwinding increases as the outer sheet material increases due to the circumferential length difference of each sheet material. There is a risk that wrinkles and creases may be formed when the layers are heat pressed.

  Therefore, it is conceivable to provide a dancer roll mechanism or the like in order to absorb the circumference difference. For example, Patent Document 2 discloses an example of a dancer roll mechanism as travel distance correction means. The dancer roll mechanism includes a pair of fixed rolls having a rotation axis fixed thereto, and a dancer roll provided between the pair of fixed rolls and having the rotation axis movable relative to the fixed roll. . When such a dancer roll mechanism is used, in addition to the laminated roll support part, a dancer roll support part is required for each of a plurality of sheets, and the laminated roll support part and the dancer roll mechanism support part interfere with each other. Otherwise, the material supply device becomes larger and the overall size of the device cannot be avoided.

  An object of this invention is to provide the manufacturing apparatus of the laminated board which can avoid the enlargement of an apparatus, and the material supply apparatus used for this.

  A laminate manufacturing apparatus and a material supply device according to the present invention include a circumference difference absorbing mechanism that is attached to a core of a laminate roll and absorbs a circumference difference of a plurality of sheet materials of the laminate roll, and the circumference difference The absorption mechanism includes one or more guide rolls for guiding each sheet material except the innermost sheet material among the plurality of sheet materials drawn from the laminated roll in the drawing direction, and the sheet material that has passed through the guide roll. And one or more tension-adding rolls that apply pressure to the sheet material from the opposite side to the guide rolls to provide tension.

  ADVANTAGE OF THE INVENTION According to this invention, when the some sheet material is pulled out from a lamination | stacking roll, the circumference difference which arises between these some sheet materials can be absorbed by the circumference difference absorption mechanism.

  In addition, since this circumferential length difference absorbing mechanism can be arranged at a position shifted in the axial direction of the laminated roll with respect to the laminated roll supporting part that supports the core of the laminated roll, a plurality of laminated roll support parts are arranged close to each other. In addition, the circumferential length difference absorbing mechanism does not interfere with these laminated roll support portions, and an increase in the size of the material supply device can be avoided.

  In addition, since the rotation posture adjusting means for adjusting the rotation posture of the circumference difference absorption mechanism is provided, the circumference difference absorption mechanism can be securely fixed to a desired rotation posture, and stable operation of the circumference difference absorption mechanism can be obtained. .

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The manufacturing apparatus of the laminated board of 1st Embodiment is demonstrated referring FIGS.

"Outline of laminated board manufacturing equipment"
First, the overall structure of the laminate manufacturing apparatus 10 of the present embodiment will be schematically described. As shown in FIG. 2, the laminated board manufacturing apparatus 10 of the present embodiment is configured to include a material supply apparatus 12, a double belt press apparatus 13 as a heat press machine, and a product winding apparatus 14. Yes.

  The material supply device 12 unwinds the multilayer workpiece 8 (a laminate of a plurality of sheet materials 4a, 4b, and 4c) from each lamination roll 5 and supplies it to the workpiece supply port of the double belt press device 13. The belt press device 13 is constituted by a known double belt press device, and a plurality of sheet materials 4a, 4b, 4c constituting the multilayer work 8 are formed by thermocompression bonding while allowing the multilayer work 8 from the material supply device 12 to pass through. Are laminated to form a laminated plate 9, and the laminated plate 9 thus laminated and formed by the double belt press device 13 is wound up by the product winding device 14.

  In addition, the manufacturing method of the lamination | stacking roll 5 is performed by winding up to the core 6 in the roll shape in the state which laminated | stacked the several elongate sheet material 4a, 4b, 4c as shown in FIG. As shown in FIG. 1, a laminating roll manufacturing apparatus 1 for manufacturing the laminating roll 5 includes single-layer rolls 3a, 3b, and 3c in which the sheet materials 4a, 4b, and 4c are separately wound into rolls. Single-layer roll support portions 2a, 2b, 2c to be pivotally supported, and multi-layer roll support portions 7 that support the core 6 for winding in a state in which the sheet materials 4a, 4b, 4c from the single-layer rolls are laminated, As a main component. In this example, the plurality of sheet materials 4a, 4b, and 4c are three, and are composed of a copper foil 4a, a polyimide film 4b, and a copper foil 4c. Therefore, the laminated board 9 manufactured with the manufacturing apparatus 10 shown in FIG. 2 becomes a double-sided copper foil laminated board (laminate sheet) by which both surfaces of the polyimide film 4b become the copper foil layers 4a and 4c. In addition, when the sheet materials 4a, 4b, and 4c are the above-described materials, the thermocompression treatment by the double belt press device 13 is performed at a pressure of 20 to 80 [bar], a temperature of 180 to 400 [° C], and a time of 1 to 10 [min]. It is desirable to perform within the range.

"Material supply device"
Next, the material supply device 12 will be described in more detail.

  As shown in FIGS. 2 and 4, the material supply device 12 includes laminated roll support portions 21 and 23 that rotatably support the core 6 of the laminated roll 5. Laminating roll support portions 21 and 23 are provided on both axial ends of the core 6, and the laminating roll support portion 21 on one axial end side is laminated on the mounting wall 20 erected vertically from the floor surface. Embedded in each roll 5, the laminated roll support portion 23 on the other end side in the axial direction is formed in a columnar shape erected vertically from the floor surface or ceiling for each laminated roll 5.

  The laminated roll support portions 21 and 23 pivotally support the winding core 6 of the laminated roll 5 via the rotating shaft 25. That is, the core 6 of the laminated roll 5 is formed in a hollow shape (cylindrical in this example), and the rotating shaft 25 penetrating through the inside of the core 6 is supported by the laminated roll support portions 21 and 23. The rotary shaft 25 has a stopper (not shown) that protrudes and protrudes in the radial direction so as to engage with the inner peripheral surface of the core 6, and the rotary shaft 25 and the core 6 are projected when the stopper projects in the radial direction. And the rotating shaft 25 and the winding core 6 rotate integrally.

  At least one of the laminating roll support portions 21 and 23 has a built-in brake means (not shown) for applying a brake against the winding of the laminated plate 9 by the product winding device 14. 8 is put into the double belt press device 13 in a stretched state.

  However, since the multilayer workpiece 8 is formed of a plurality of sheet materials 4a, 4b, and 4c (thickness t1, t2, and t3), the outer sheet material 4c is an intermediate sheet when unrolled from the laminated roll 5. The material 4b is also unwound longer by 2π × (t2) / 2 per turn, and the inner sheet material 4a is unwound longer by 2π × (t2 + t3) / 2 per turn.

  Therefore, when the multilayer workpiece 8 is inserted into the double belt press device 13, the sheet material 4a, 4b, 4c is not accurately laminated at the workpiece insertion port of the double belt press device 13, and wrinkles or the like are generated. May cause molding defects. Therefore, in order to prevent such a problem from occurring, the material supply device 12 of the present embodiment is configured to include a circumferential length difference absorption mechanism 30.

"Circumferential length absorption mechanism"
Next, the circumference difference absorbing mechanism 30 will be described with reference to FIGS.

  The circumferential length difference absorbing mechanism 30 absorbs the circumferential length differences of the plurality of sheet materials 4 a, 4 b, 4 c of the laminated roll 5. The circumferential difference absorbing mechanism 30 of this embodiment is attached to the core 6 of the laminated roll 5. More specifically, the configuration is as follows.

  In the circumferential length difference absorbing mechanism 30 of this embodiment, as shown in FIGS. 4 to 8, a pair of opposing plate-like mounting bases suspended via bearings 39 on both axial ends of the core 6 of the laminated roll 5. 35 is provided. The pair of opposed mounting bases 35 are pivotally supported in a state where guide rolls 36 and 37 are suspended so as to be parallel to the core 6, and a pair of support arms 31 and a pair of support arms 33 are provided. It is pivotally attached. Both ends in the axial direction are pivotally supported on the rotation free ends of the pair of support arms in a state where the tension applying rolls 32 and 34 are installed so as to be parallel to the core 6.

  The guide rolls 36 and 37 are for guiding the sheet materials 4b and 4c drawn from the laminated roll 5 in the drawing direction. Further, the tension applying rolls 32 and 34 apply tension to the sheet material 4b and 4c that have passed through the guide rolls 36 and 37 by pressing from the side opposite to the guide rolls 36 and 37, respectively. Here, the number of the guide rolls 36, 37 and the tension applying rolls 32, 34 may be the same as the number of the sheet materials 4a, 4b, 4c. In this example, the guide rolls 36, 37 and the tension applying rolls are used. 32, 34 are provided for each of the sheet materials 4b, 4c except for the innermost sheet material 4a among the plurality of sheet materials 4a, 4b, 4c, and the innermost sheet material 4a is a guide roll and tension. Since the product take-up device 14 is wound through the double belt press device 13 without passing through the additional roll, the number of the guide rolls 36 and 37 and the tension applying rolls 32 and 34 is the sheet material 4a, 4b, 4c. It is one less than the number of sheets. In other words, in this example, the number of sheet materials of the multilayer workpiece 8 is two, and the guide rolls 36 and 37 and the tension applying rolls 32 and 34 are two, which is one less.

  The support arms 31 and 33 are urged by the urging means so that the support arms 31 and 33 rotate in the direction in which the tension applying rolls 32 and 34 are pressed against the sheet materials 4b and 4c. The biasing means of this embodiment has a structure in which flexible members (for example, wires) 43 and 45 connected to the support arms 31 and 33 are pulled by a slider 42 that is driven by an electric motor 41. In the present invention, the urging means can be realized in various forms such as a spring member and an air cylinder. In the present invention, the tension applying rolls 32 and 34 are pressed against the sheet materials 4b and 4c by the weights of the tension applying rolls 32 and 34 and the support arms 31 and 33 without providing the urging means. good.

  By such a circumferential length difference absorbing mechanism 30, the unwinding length between the plurality of sheet materials 4a, 4b, 4c put into the double belt press device 13 is absorbed. Specifically, as shown in FIG. 5 → FIG. 6 → FIG. 7, as the multilayer work 8 is unwound from the laminated roll 5, the outer sheet material becomes more slack, so that it is supported to absorb this. The arms 31 and 33 are rotated. Thereby, it is prevented that wrinkles generate | occur | produce in the laminated board 9 manufactured.

"Desorption structure of the circumference difference absorption mechanism"
Here, in the circumferential length difference absorbing mechanism 30 of the present embodiment, as shown in FIGS. 5 to 8, the mounting base 35 is configured to be detachable from both axial ends of the core 6. More specifically, the attachment base 35 is formed with a fixing portion 51 for fixing the bearing units 38 attached to both axial ends of the core 6 so as to be detachable from the radial direction. The bearing unit 38 and the fixed portion 51 are configured with a fitting structure, and the bearing unit 38 is fitted into the fixed portion 51. The fixing portion 51 of the mounting base 35 is open to the periphery of the mounting base 35 so that the bearing unit 38 can be inserted from the radial direction. The opening portion of the fixing portion 51 is closed by a lid portion 55 that is fastened to the mounting base body by two first clamps 57 and 57. Further, a second clamp 59 that is orthogonal to the tightening direction of the first clamp 57 is further mounted on the mounting base 35, and the bearing unit 38 in the fixed portion 51 is tightened by the second clamp 59. It is like that.

  Thus, in this embodiment, since the circumference difference absorption mechanism 30 is detachable with respect to the core 6, the circumference difference absorption mechanism 30 can be used by simply replacing the laminated roll 5.

  The bearing unit 38 includes a bearing 39 that is press-fitted and fixed to the core 6 and a plate-like bearing mounting base 40 that is fixed to the outer peripheral side of the bearing 39. May be constituted only by the bearing 39.

"Rotating posture adjustment means"
Next, the rotation attitude adjustment means 60 that adjusts the rotation attitude of the circumference difference absorbing mechanism 30 around the core 6 will be described with reference mainly to FIGS. FIG. 9 is a diagram in which members other than the mounting base 35 of the circumferential length difference absorbing mechanism are removed in order to schematically show the positional relationship between the mounting base 35 of the circumferential length difference absorbing mechanism 30 and the rotation posture adjusting means 60. Show.

  Since the circumference difference absorbing mechanism 30 is suspended from the core 6 via the bearing 39, the circumference difference absorbing mechanism 30 is attached to the core 6 by its own weight. Although the posture is kept constant, there is a possibility that the circumference difference absorbing mechanism 30 may wobble around the core 6 when the winding core 6 rotates or when an external force is applied to the circumference difference absorbing mechanism 30. Further, if the position where the posture is maintained by the own weight of the circumference difference absorbing mechanism 30 is the use position of the circumference difference absorbing mechanism 30, the actual rotation posture is deviated from the use position required due to variations in the center of gravity position. There is a fear.

  Therefore, in this embodiment, the rotation attitude | position adjustment means 60 for maintaining the circumference difference absorption mechanism 30 in a desired rotation attitude | position is provided.

  As shown in FIGS. 9 to 13, the rotation posture adjusting means 60 of the present embodiment is attached to a base 61 that is directly or indirectly fixed to the laminated roll support portions 21 and 23, and is rotatably attached to the base 61. A rotating member 63 that rotates about the core 6, a driving means 65 that is fixed to the base 61 and that rotates the rotating member 63, and an engagement formed on the mounting base 35 of the circumferential difference absorbing mechanism 30. An engaging portion 67 is formed on the rotating member 63 so as to engage with the portion 35a and rotate the rotating member 63 and the mounting base 35 integrally.

  As shown in FIGS. 10 and 12, the base 61 includes a plate-like member 61a and a cylindrical boss 61b fixed to the plate-like member 61a. The rotating member 63 includes a first rotating member 63a rotatably mounted on the outer periphery of the boss 61b of the base 61 via a bearing, and a plate fixed to the first rotating member 63a by fixing means such as a pin. And a second rotating member 63b having a shape. The driving means 65 includes an electric motor 65a and a worm gear 65b rotated by the electric motor 65a, and the worm gear 65b meshes with a gear 63c formed on the outer periphery of the first rotating member 63a. Yes. Thus, when the electric motor 65a is driven, the rotating member 63 rotates.

  The engaging portion 67 of the rotating member 63 is configured as an expansion / contraction rod, while the engaging portion 35a of the mounting base 35 is configured as an engagement hole through which the distal end portion of the expansion / contraction rod 67 can enter and retract. When a first button (not shown) is pressed, the distal ends of the telescopic rods 67 enter the engagement holes 35a of the mounting base 35 and are locked to each other as shown in FIGS. In this state, when the worker pushes the second button 69 (see FIG. 10) to drive the electric motor 65a, the rotating member 63 rotates and the circumferential length difference absorbing mechanism 30 is attached integrally with the rotating member 63. The base 35 also rotates around the core 6.

  At this time, the operator may adjust the rotation posture of the mounting base 35 by adjusting ON / OFF of the second button 69, but the rotation posture of the mounting base is automatically adjusted using a sensor or the like. May be. In the present embodiment, when the rotating member 63 is driven to rotate by the driving means 65, the rotating member 63 is stopped as the first stopping means for stopping the rotation in the first rotation posture (see the two-dot chain line in FIG. 11). A first sensor 71 (see FIG. 11), and a second sensor 72 (see FIG. 11) as a second stopping means for stopping the rotation in the second rotation posture (see the two-dot chain line in FIG. 11). It is equipped with. The first sensor 71 and the second sensor 72 come into contact with the rotating member 63 when the rotating member 63 rotates to the first rotation posture (see the two-dot chain line in FIG. 11), and the drive unit 65 is electrically The power supply to the motor 65a is configured to stop. Similarly to the first sensor 71, the second sensor 72 is configured so that the rotating member 63 is in the second rotation posture (two-dot chain line in FIG. 11). It is configured to stop the supply of electric power to the electric motor 65a of the driving means 65 when it rotates to the reference).

  The definition of the first rotation posture is that the engagement portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30 and the engagement portion 67 of the rotation member 63 of the rotation posture adjusting means 60 are not engaged. At the position where the length difference absorbing mechanism 30 is stabilized by its own weight, the engaging portion 67 of the rotating member 63 of the rotation posture adjusting means 60 is opposed to the engaging portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30. The position where it can be freely combined. The definition of the second rotational posture is defined by the state in which the engaging portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30 and the engaging portion 67 of the rotating member 63 of the rotational posture adjusting means 60 are engaged. The position where the long-difference absorbing mechanism 30 is used is a rotational posture set in advance by calculation or simulation.

  These sensors 71 and 72 are used as follows when the circumference difference absorbing mechanism 30 is set.

  First, with respect to the core 6 supported by the laminated roll support portions 21 and 23, the circumference difference absorbing mechanism 30 is mounted on the core 6 of the laminated roll 5, and the core 6 of the laminated roll 5 is supported by the laminated roll. It supports to the parts 21 and 23 (refer FIG. 4, FIG. 9). In this state, as shown in FIGS. 4 and 9, the posture is kept constant at a position where the center of gravity of the circumferential difference absorbing mechanism 30 is stable with the circumferential difference absorbing mechanism 30 hanging from the core 6. It is. At this time, the mounting bracket 30 of the circumference difference absorbing mechanism 30 is in the first rotation posture.

  Next, the second button 69 is turned on, and the rotating member 63 is rotated counterclockwise by the driving means 65. Then, the rotating member 63 to be driven to rotate contacts the first sensor 71 in the first rotating posture shown in FIG. 11, and thereby the driving means 65 stops and the rotating member 63 stops in the first rotating posture. . In this first rotational posture, the engaging portion 67 of the rotating member 63 faces the engaging portion 3a of the mounting base 35 so that the engagement can be released.

  Next, the first button (not shown) is turned on to project the telescopic rod 67 as the engaging portion of the rotating member 63, and the telescopic rod 67 serves as the engaging hole 35 a as the engaging portion of the mounting base 35. To enter. As a result, the engaging portion 67 of the rotating member 63 and the engaging portion 35a of the mounting base 35 are engaged, so that the mounting base 35 and the rotating member 63 can rotate integrally.

  Next, the second button 69 is turned on again, and the rotating member 63 is rotated in the reverse direction to rotate clockwise. Then, the rotating member 63 to be driven to rotate comes into contact with the second sensor 72 in the second rotation posture shown in FIG. 11, whereby the driving means 65 stops and rotates in the second rotation posture as the use position. The member 63 stops. Thereby, the circumference difference absorption mechanism 30 will be located in the preset use position. In this state, the laminated plate manufacturing apparatus 10 is finally operated to manufacture the laminated plate 9.

  As described above, in the present embodiment, since the first sensor 71 as the first stopping unit and the second sensor 72 as the second stopping unit are provided, the circumference difference absorption by the rotational attitude adjusting unit 60 is absorbed. The mechanism 30 can be set very easily.

  Next, effects of the present embodiment will be enumerated.

  (1) The laminated sheet manufacturing apparatus 10 and the material supply apparatus 12 used for the laminated sheet manufacturing apparatus 10 of the present embodiment absorb a circumferential length difference between the plurality of sheet materials 4a, 4b, and 4c drawn from the laminated roll 5. 30. Therefore, the circumferential length difference absorbing mechanism 30 can absorb the circumferential length difference generated between the plurality of sheet materials 4 a, 4 b, 4 c constituting the multilayer workpiece 8 when the multilayer workpiece 8 is pulled out from the laminated roll 5. As a result, the laminated state of the multilayer workpiece 8 can be stabilized at the workpiece insertion port of the hot press machine 13, and manufacturing defects such as wrinkles entering the manufactured laminated plate 9 can be prevented.

  (2) In this embodiment, the circumference difference absorbing mechanism 30 is attached to the core 6 of the laminated roll 5. Therefore, since the circumference difference absorbing mechanism 30 can be disposed at a position shifted in the axial direction with respect to the laminated roll support portions 21 and 23, even if the plurality of laminated roll support portions 21 and 23 are disposed close to each other in the radial direction. The circumference difference absorbing mechanism 30 can be prevented from interfering with the laminated roll support portions 21 and 23, and the material supply device 12 can be prevented from being enlarged.

  In particular, in a structure in which the number of sheet materials constituting the multilayer workpiece 8 is three or more, a plurality of laminated rolls 5 can be easily arranged close to each other.

  (3) In this embodiment, the mounting base 35 of the circumferential length difference absorbing mechanism 30 is suspended from the core 6 via the bearing 39, so that the circumferential length difference absorbing mechanism (mounting) In the state where the base 35) is mounted, the posture is kept constant by the weight of the circumferential length difference absorbing mechanism 30, but when the winding core 6 rotates or when an external force is applied to the circumferential length difference absorbing mechanism 30, the circumferential length difference absorbing mechanism 30 is rotated. There is a possibility that the long-difference absorbing mechanism 30 may wobble around the core 6. Further, if the position where the posture is maintained by the weight of the circumference difference absorbing mechanism 30 is the position where the circumference difference absorbing mechanism 30 is used, a deviation occurs between the required rotation posture and the actual rotation posture due to variations in the center of gravity position. There is a risk that.

  However, in the present embodiment, the rotation attitude adjustment means 60 that adjusts the rotation attitude of the circumference difference absorbing mechanism 30 is provided. Therefore, in the present embodiment, the circumferential difference absorbing mechanism 30 can be reliably fixed in a desired rotation posture, the stable operation of the circumferential difference absorbing mechanism 30 can be obtained, and the laminate 9 to be manufactured can be further manufactured. It becomes difficult to enter cocoons.

  (4) Moreover, in this embodiment, the rotation attitude | position adjustment means 60 is the rotation member 63 rotatably mounted with respect to the lamination roll support parts 21 and 23 so that it may rotate centering around the core 6 of the lamination roll 5. A driving means 65 fixed to the laminating roll support portions 21 and 23 or the rotating member 63 and rotating the rotating member 63 with respect to the laminating roll support portions 21 and 23; and a circumferential length difference absorbing mechanism provided on the rotating member 63. 30 is provided with an engagement portion 67 that engages with an engagement portion 35a formed on the attachment base 35 of the 30 to enable the rotation member 63 and the attachment base 35 to rotate integrally. 60 will be configured.

  (5) Further, in this embodiment, the engaging portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30 and the engaging portion 67 of the rotating member 63 of the rotation posture adjusting means 60 are not engaged, and the circumferential length difference absorbing mechanism. In a state where 30 is stabilized by its own weight, a position where the engaging portion 67 of the rotating member 63 of the rotation posture adjusting means 60 can be disengaged with respect to the engaging portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30. The first rotation posture of the mounting base 35 and the rotation member 63 is the first rotation position where the drive member 65 is stopped at a position where the rotation member 63 assumes the first rotation posture when the rotation member 63 is driven to rotate by the drive unit 65. The stopping means 71 is provided. Therefore, when the rotation member 63 is rotationally driven in a state where the circumference difference absorbing mechanism 30 is stabilized by its own weight, the engagement portion 35a of the mounting base 35 of the circumference difference absorbing mechanism 30 and the rotation posture adjusting means 60 are automatically rotated. The member 63 stops at a position where the engaging portion 67 of the member 63 faces and becomes freely engageable. Therefore, the work of mounting the rotation posture adjusting means 60 on the circumference difference absorbing mechanism 30 becomes extremely easy.

  (6) Further, in the present embodiment, the circumferential length difference is obtained in a state where the engaging portion 35 a of the mounting base 35 of the circumferential length difference absorbing mechanism 30 is engaged with the engaging portion 67 of the rotating member 63 of the rotation posture adjusting means 60. The position where the absorption mechanism 30 is used is the second rotation posture of the mounting base 35 and the rotation member 63, and the rotation member 63 is in the second rotation posture when the rotation member 63 is driven to rotate by the driving means 65. Second stop means for stopping the drive means 65 is provided. Therefore, when the rotating member 63 is rotationally driven in a state where the engaging portion 35a of the mounting base 35 of the circumferential length difference absorbing mechanism 30 and the engaging portion 67 of the rotating member 63 of the rotation posture adjusting means 60 are engaged, In other words, the circumference difference absorbing mechanism 30 is set to the use position. Therefore, the adjustment operation of the rotation posture of the circumference difference absorbing mechanism 30 using the rotation posture adjustment means 60 becomes extremely easy.

  In the present embodiment, the first stop means 71 and the second stop means 72 are contact type sensors, but other sensors such as a non-contact type sensor may be used as the stop means. May include a rotation sensor that detects a rotation angle and a control circuit that stops the driving unit at a predetermined position based on a detection result of the rotation sensor.

  (7) In the present embodiment, the circumferential difference absorbing mechanism 30 includes a pair of mounting bases 35 suspended from both ends of the core 6 of the laminated roll 5 in the axial direction via bearings 39, and a pair of mounting bases 35. Guide rolls 36 and 37 that are pivotally supported between them and guide the sheet material 4b and 4c drawn out from the laminated roll 5 in the pull-out direction, a pair of support arms 31 and 33 pivotally attached to a pair of mounting bases 35, and a pair of A tension-adding roll that is supported between the rotation free ends of the support arms 31 and 33 and applies tension to the sheet material 4b and 4c that have passed through the guide rolls 36 and 37 by pressing from the opposite side to the guide rolls 36 and 37. 32, 34.

  Therefore, the circumference difference absorption mechanism 30 attached to the core 6 of the laminated roll 5 has a simple configuration and contributes to cost reduction of the apparatus. Moreover, since the longitudinally opposite ends of the tension applying rolls 32 and 34 are supported by the pair of support arms 31 and 33, the tension applying rolls 32 and 34 have high stability, and the sheet materials 4a, 4b, and 4c are less likely to become wrinkles. Become.

  (8) In the present embodiment, each of the sheet materials 4b and 4c excluding the innermost sheet material 4a in the multilayer work (consisting of a plurality of laminated sheet materials 4a, 4b, and 4c) drawn from the lamination roll 5 is used. On the other hand, guide rolls 36 and 37 and tension applying rolls 32 and 34 are provided. That is, the number of the guide rolls 36 and 37 and the tension applying rolls 32 and 34 is one less than the number of sheet materials. Therefore, since the tension applying rolls 32 and 34 and the support arms 31 and 33 that support the tension applying rolls 32 and 34 are minimized, the number of parts is reduced, which contributes to cost reduction.

  (9) Further, in the present embodiment, the support arms 31 and 33 are rotatably supported on the guide rolls 36 and 37 side with respect to the core 6. For this reason, the lengths of the support arms 31 and 33 can be shortened, thereby further reducing the size of the apparatus.

  (10) In the present invention, the rotation centers of the plurality of support arms 31 and 33 may be matched. However, if the rotation centers of the plurality of support arms 31 and 33 are matched, the plurality of support arms 31 are matched. , 33 need to be laminated in the axial direction of the core 6. On the other hand, in this embodiment, since the rotation centers of the plurality of support arms 31 and 33 are shifted without being coincident with each other, it is not necessary to increase the size in the axial direction of the core 6.

  (11) Moreover, in this embodiment, the attachment base 35 is detachable with respect to the bearing units 38 attached to both axial ends of the core 6. Therefore, the circumference difference absorbing mechanism 30 can be attached to and detached from the core 6 of the laminated roll 5, so that the circumference difference absorbing mechanism 30 can be used only by replacing the laminated roll 5.

(Second Embodiment)
Next, a second embodiment will be described. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the configuration and the operation and effect thereof are omitted.

  In the second embodiment shown in FIG. 14, the circumference difference absorbing mechanism 30 is different from the first embodiment in that the support arm 31, the tension applying roll 32, and the guide roll 36 are one.

  Further, in the second embodiment, the rotation posture adjusting means 80 includes a telescopic rod 81 whose proximal end is fixed with respect to a fixed point (for example, a floor surface, a laminated roll support part, or another fixed point), and a distal end of the telescopic rod 81. And a flexible member (for example, a wire) 83 that connects the side and the mounting base 35 of the circumferential length difference absorbing mechanism 30. The telescopic rod 81 includes a base portion 81a that is fixed to a fixed point, and a protruding portion 81b that is slidably supported by the base portion 81a, and is flexible to the protruding portion 81b on the distal end side. One end of the member 83 is connected.

  Thereby, by expanding and contracting the telescopic rod 81, the rotation posture of the circumference difference absorbing mechanism 30 can be adjusted, and the effect similar to that of the above-described first embodiment can be obtained also in such a second embodiment. .

(Third embodiment)
Next, a third embodiment will be described. In the third embodiment shown in FIG. 15, the rotation posture adjusting means 90 includes an extendable rod 91 that is pivotally supported on the base end side with respect to a fixed point. The telescopic rod 91 includes a base portion 91a pivotally attached to a fixed point, and a protruding portion 91b that is slidably supported with respect to the base portion 91a, and the protruding portion 91b on the distal end side has a difference in circumferential length. It is connected to the mounting base 35 of the absorption mechanism 30.

  Thereby, the rotation posture of the circumference difference absorbing mechanism 30 can be adjusted by rotating the base portion 91a and sliding the protruding portion 91b. In the third embodiment as well, the above-described first embodiment is performed. The same effect as the form can be obtained.

  As mentioned above, although this invention was demonstrated taking the above-mentioned embodiment as an example, this invention is not limited only to the above-mentioned embodiment.

  For example, the copper foil may be a metal foil other than a copper foil such as an aluminum foil or a stainless steel foil, and the polyimide film may be a liquid crystal polymer, an aramid film, a pet film, an ultra-thin glass cloth base epoxy resin sheet, or the like. Various film-like substrates other than the polyimide film may be used.

  In the above-described embodiment, the case where the multi-layer workpiece is composed of two or three sheet materials has been described. However, if the multi-layer workpiece is composed of a plurality of sheet materials, the number of sheet materials is not concerned. The present invention can be applied.

  In the above-described embodiment, six laminated plates are laminated at the same time. However, in the present invention, one laminated plate may be laminated. However, the more the number of laminated plates manufactured simultaneously, that is, the larger the number of laminated rolls, the more limited the space for arranging the supporting portions of the laminated rolls.

  Further, in the above-described embodiment, the winding core is attached to the laminated roll support portion via the rotating shaft. However, in the present invention, the winding core is directly attached to the laminated roll support portion not via the rotating shaft. Also good.

  In the above-described embodiment, the bearing unit 38 includes the bearing 39 that is press-fitted and fixed to the core 6, and the plate-shaped bearing mounting base 40 that is fixed to the outer peripheral side of the bearing 39. However, in the present invention, the bearing unit 38 may be configured by only the bearing 39 as long as the mounting base 35 can removably fix the bearing unit 38.

  In the first embodiment, the mounting base 35 of the circumferential difference absorbing mechanism 30 allows the bearing unit 38 of the core 6 of the laminated roll 5 to be detachable, but the mounting base 35 is attached to the core 6 of the laminated roll 5. On the other hand, the present invention can be applied to a structure that is not detachable.

  In the above-described embodiment, in order to minimize the number of guide rolls, tension applying rolls, and support arms, the number of guide rolls, tension applying rolls, and support arms is one less than the number of sheets constituting the multilayer work. However, in the present invention, the number of sheets and the number of guide rolls, tension applying rolls, and support arms may be the same or larger.

  In addition, it is needless to say that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on the above embodiment are all included in the scope of the present invention.
