Side).

<About the configuration of the sheet take-out device>
FIG. 1 is a schematic diagram showing a configuration of the sheet take-out device 10. As shown in FIG. As shown in FIG. 1, the sheet take-out apparatus 10 mainly includes a first suction unit 20, a second suction unit 120, a mounting table unit 200, a control unit 210, and a suction bed 220 (see FIG. 5). Components.

  Among them, the first suction unit 20 includes the suction holding unit 30, the rotation mechanism 40, the suction mechanism 50, the elevating mechanism 60, and the separation plate unit 70. Among these, the suction holding unit 30 corresponds to a part of the first suction unit. Note that the first suction unit corresponds to not only the suction holding unit 30 but also the suction mechanism 50.

  FIG. 2 is a diagram illustrating a schematic configuration of the suction holding unit 30. The suction holding section 30 shown in FIG. 2 is for holding the sheet-shaped member S by suction, and is attached to a support shaft 41 constituting the rotating mechanism 40. The suction holding section 30 includes a suction pad 31, and the suction pad 31 is attached to a support arm 32.

  The material of the suction pad 31 is formed of an elastic member having elasticity such as rubber or elastomer. Therefore, even if the sheet contact portion 31a on the tip end side of the suction pad 31 contacts the sheet member S, the sheet member S is not damaged. The suction pad 31 is a tubular member provided in a bellows shape. Therefore, since the direction of the sheet contact portion 31a can be easily changed following the sheet member S, even if the sheet member S is deformed such as warpage, the sheet member S follows the deformation. It is possible.

  Further, the suction pad 31 is attached to the tip end (one end) of the support arm 32. The support arm 32 is formed of a rigid member such as a metal, for example, and can support the suction pad 31 and the suction branch conduit. Further, the support arm 32 is rotated by the rotation mechanism 40 so that a contact operation in which the suction pad 31 abuts on the sheet member S and a retracting operation separating from the sheet member S can be performed. Has become.

  FIG. 3 is a diagram illustrating a schematic configuration of the suction holding unit 30, the rotation mechanism 40, the suction mechanism 50, and the elevating mechanism 60. The rotation mechanism 40 includes a support shaft 41, a support column 42, and a rotation actuator 43. The support shaft 41 is a portion to which the other end of the support arm 32 is attached, and is a member that is rotated by the operation of a rotation actuator 43 described later. The support shaft 41 is a shaft member rotatably supported at at least two places by support columns 42. The support column 42 is a member that stands upright from the frame 44, and is a portion that supports the support shaft 41 and the suction holding unit 30. The frame 44 is a member that supports the support column 42, and corresponds to, for example, a long metal member disposed below the support column 42.

  A rotation actuator 43 is attached to one end of the support shaft 41 via a drive transmission mechanism 45. The operation of the rotation actuator 43 causes the support shaft 41 to rotate. One end in this pivoting operation is the end point of the operation in which the suction pad 31 abuts on the sheet member S, and the other end in the pivoting operation is the end point of the retreat operation separating from the sheet member S. . Here, as the rotation actuator 43, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, a solenoid, a motor, or the like can be used. The rotation actuator 43 may be directly connected to the support shaft 41.

  The suction mechanism 50 includes a suction pump 51 and a suction pipe 52. The suction pump 51 applies a negative pressure for sucking and holding the sheet member S by the suction pad 31. One end of a suction pipe 52 is connected to the suction pump 51, and the other end of the suction pipe 52 is connected to the suction pad 31. Therefore, when the suction pump 51 operates and the suction pad 31 contacts the sheet member S, the sheet member S can be suction-held by the suction pad 31.

  The suction conduit 52 may be any tubular member that allows air to flow, such as a tube formed of an elastic material, a metal or resin pipe, and the like. When the above-described support arm 32 is provided in a cylindrical shape, the support arm 32 also corresponds to one component of the suction conduit 52.

  The elevating mechanism 60 is a mechanism for elevating and lowering at least a part of the suction holding unit 30, the rotating mechanism 40, and the suction pipe 52. The elevating mechanism 60 may raise and lower not only at least a part of the suction pipe 52 but also the suction pump 51. The elevating mechanism 60 corresponds to first elevating means. The elevating mechanism 60 is disposed on each of both ends of the frame 44 in the longitudinal direction. The lifting mechanism 60 includes a suspension member 61 and a lifting cylinder 62.

  The suspension member 61 is a mechanism that connects the end of the frame 44 and the tip of the cylinder rod of the elevating cylinder 62. For example, a link mechanism or a bearing can be used. In particular, when a link mechanism is used, the lifting cylinder 62 at one end of the frame 44 and the lifting cylinder 62 at the other end of the frame 44 can be moved up and down at different timings. The suction holding unit 30 and the like supported by the frame 44 can be inclined.

  However, the suspension member 61 may connect the frame 44 and the elevating cylinder 62 with, for example, a metal columnar member without using a link mechanism or a bearing. Since the cylinder rod of the lifting cylinder 62 cannot normally be tilted, when the suspension member 61 is formed of a metal columnar member, the lifting cylinder 62 on one end of the frame 44 and the frame It is preferable that the elevating cylinder 62 on the other end side of 44 performs the operation of elevating and lowering at the same timing.

  The elevating cylinder 62 provides a driving force for elevating the frame 44 and the suction holding unit 30. As the elevating cylinder 62, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, a solenoid, a motor, or the like can be used.

  FIG. 4 is a diagram showing a schematic configuration of the separation plate unit 70. As shown in FIG. 4, the separation plate unit 70 includes a separation plate 71, a support arm 72, a connection beam 73, a separation plate actuator 74, and a guide member 75. When the uppermost sheet-shaped member S of the stacked body PS (see FIG. 5) is lifted while being held by the suction holding unit 30, the separation plate 71 is located immediately below the lifted sheet-shaped member S. This is a plate-like member inserted between the sheet-like member S and the sheet-like member S. By inserting the separation plate 71, even if the sheet-like member S held by the suction holding unit 30 later falls, it is possible to prevent the sheet-like member S from coming into close contact with the immediately below sheet-like member S and not separating. . Note that the separation plate 71 corresponds to a separation unit.

  Here, the separation plate 71 is formed of a material that does not easily damage the sheet-shaped member S. Specifically, the separation plate 71 is formed of a material that can be easily deformed even when a pressing force is applied by the sheet-shaped member S. Examples of such a material include spring steel and elastic resin. In addition, from the viewpoint of preventing dust from adhering to the sheet member S, the material of the separation plate 71 is preferably spring steel.

  The support arm 72 is a member that supports the separation plate 71, and holds one end of the separation plate 71. The connecting beam 73 is a member connecting a plurality of (three in FIG. 1 and FIG. 4) support arms 72. Further, the separation plate actuator 74 corresponds to a moving unit, and performs an operation of moving the support arm 72 toward and away from the sheet-shaped member S. As the separation plate actuator 74, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, a solenoid, a motor, or the like can be used. In the present embodiment, the separation plate actuator 74 is attached so as to move the connection beam 73. The guide member 75 is a member that guides the movement of the connection beam 73 by the operation of the separation plate actuator 74, and corresponds to, for example, a rail-shaped member or a linear guide.

  In addition, as shown in FIG. 1, the second suction unit 120 has the same configuration as the first suction unit 20. Specifically, the second suction unit 120 includes a suction holding unit 130, a rotation mechanism 140, a suction mechanism 150, a lifting mechanism 160, and a separation plate unit 170.

  That is, the suction holding unit 130 includes the suction pad 131 having the sheet contact part 131a and the support arm 132. The suction holding unit 130 corresponds to a part of the second suction unit. The rotation mechanism 40 includes a support shaft 141, a support pillar 142, a rotation actuator 143, and a frame 144. Further, the suction mechanism 150 includes a suction pump 151 and a suction pipe 152. Note that the suction mechanism 150 corresponds to a part of the second suction unit. The lifting mechanism 160 includes a suspension member 161 and a lifting cylinder 162. The elevating mechanism 160 corresponds to a second elevating means. The separation plate unit 170 includes a separation plate 171, a support arm 172, a connection beam 173, a separation plate actuator 174, and a guide member 175. The separating plate 171 corresponds to a separating unit, and the separating plate actuator 174 corresponds to a moving unit. Each of these parts has the same configuration as that of the corresponding part of the first suction unit 20, and a description thereof will be omitted.

  The sheet take-out device 10 includes a mounting table unit 200. FIG. 5 is a schematic diagram illustrating a configuration of the sheet take-out device 10 including the mounting table unit 200 and the suction bed 220, and is a diagram illustrating a state where the sheet take-out device 10 is viewed from the side. As shown in FIG. 5, the mounting table unit 200 includes a mounting table 201, a lifting guide 202, and a mounting table cylinder 203.

  The mounting table 201 is a member provided in a flat plate shape, and a large number of sheet members S are mounted on the upper surface thereof. In addition, the lifting guide 202 is disposed at a predetermined interval on the edge side of the mounting table 201 (for example, a concave portion provided on the edge side of the mounting table 201), so that the mounting table 201 is displaced. However, it is a member that guides ascending and descending in the vertical direction (Z direction). The mounting table cylinder 203 is a member that gives a driving force to move the mounting table 201 in the vertical direction (Z direction). As the mounting table cylinder 203, for example, an air cylinder, a hydraulic cylinder, an electromagnetic cylinder, a solenoid, a motor, or the like can be used.

  The sheet take-out device 10 includes a control unit 210. The control unit 210 is a part that controls the driving of each driving unit of the first suction unit 20 and the second suction unit 120. Specifically, the control unit 210 controls the driving of the rotation actuators 43 and 143, the suction pumps 51 and 151, the lifting cylinders 62 and 162, and the separation plate actuators 74 and 174.

  The control unit 210 corresponds to a control unit. The control unit 210 is, for example, a computer, and can execute various control operations by executing predetermined control data and a predetermined control program stored in a memory including an external storage device. The control operation performed by the control unit 210 will be described later.

  As shown in FIG. 5, the suction bed 220 includes a suction plate 221, a moving mechanism connecting portion 222, a suction unit (not shown), and a moving mechanism (not shown). The suction plate 221 is provided with a plurality of suction holes (not shown). For this reason, the suction plate 221 can suck the sheet-shaped member S in a planar shape. The moving mechanism connecting part 222 is a part connected to a moving mechanism (not shown). Therefore, the operation of the moving mechanism makes it possible to lower the suction plate 221 or to convey the sheet-shaped member S sucked by the suction bed 220 to another processing site.

  The sheet-shaped member S is a sheet-shaped member used for manufacturing a flexible printed board, and corresponds to, for example, a copper foil sheet, a polyimide sheet, or the like. The sheet member S such as a copper foil sheet or a polyimide film may have a separate film member such as a release film or a protective film attached to a base material such as a copper foil film or a polyimide film. It is not necessary that a proper film member is attached. When a separate film member is attached to a base material such as a copper foil material or a polyimide material in the sheet-like member S, the sheet-like member S is formed due to a difference in heat shrinkage between the base material and the film member. Is in a state where warpage is likely to occur.

<Control operation>
A method for manufacturing a flexible printed board using the sheet take-out device 10 configured as described above will be described below. In the following description, the first to seventh steps are sequentially described, but it goes without saying that various other steps may be present.

(1) First step: suction holding of the uppermost sheet-shaped member S (first control)
First, as shown in FIG. 5, a stacked body PS on which a number of sheet-shaped members S are stacked is set at a predetermined mounting position. Thereafter, as shown in FIG. 6, the control unit 210 moves the tip of the suction pad 31 of the suction holding unit 30 to the uppermost sheet-shaped member S of the laminate PS (hereinafter, this sheet-shaped member S is referred to as a sheet-shaped member). (S1), the mounting table cylinder 203 is operated so that the mounting table 201 is raised to a prescribed raising position. At this time, the control unit 210 operates the suction pump 51 of the suction mechanism 50 to cause the uppermost sheet-shaped member S to be suction-held by the suction pad 31.

  Here, the uppermost sheet-shaped member S1 with which the suction pad 31 is in contact may be warped such that its end side is directed upward (Z1 side). However, the suction pad 31 is provided in a bellows shape and is elastically deformable. Therefore, even if the tip of the suction pad 31 abuts on the warped portion of the sheet-like member S1, the suction pad 31 can be deformed to follow the warpage. Therefore, when the leading end of the suction pad 31 comes into contact with the uppermost sheet-like member S1, it is possible to prevent the contact portion from being damaged.

  Note that the control unit 210 may operate the lifting cylinder 62 so that the suction pad 31 is lowered toward the sheet member S1 instead of raising the mounting table cylinder 203. Even in this case, the uppermost sheet-shaped member S1 can be suction-held.

(2) Second step: Separation of uppermost sheet-shaped member S1 from laminate PS (third control)
Next, as shown in FIG. 7, the controller 210 controls the uppermost sheet-like member S in a state where the suction pad 31 sucks and holds the uppermost sheet-like member S (that is, with the suction pump 51 operated). The mounting table cylinder 203 and the lifting cylinder 62 are operated so that the member S is separated from the stacked body PS.

  Specifically, the control unit 210 operates the mounting table cylinder 203 so as to lower the mounting table 201 to a prescribed retreat position. Thus, a relatively large space is formed between the stacked body PS and the sheet member S1 held by suction. At this time, after the sheet-like member S1 is lifted, a range in which the topmost sheet-like member S (hereinafter, this sheet-like member S is referred to as a sheet-like member S2) in the remaining stacked body PS is assumed. Even if the sheet S1 is greatly warped, a space is formed between the sheet-like member S1 and the sheet-like member S2 such that a gap is reliably formed.

(3) Third step: Implementation of swing-off operation (second control)
By the way, when the uppermost sheet-like member S1 is lifted, the next-order sheet-like member S2 which has been adjacent when the sheet-like members S1 are stacked may be lifted together. Further, a plurality of sheet members S including the next sheet member S2 may be lifted. In particular, when the surface roughness of the sheet-shaped member S is very small (when the sheet-shaped member S is very smooth), it is difficult for air to enter between the adjacent sheet-shaped members S. This makes it easier for such sheet-like members S to be held in close contact with each other (hereinafter, a large number of sheet-like members S are taken).

  Therefore, after lifting the uppermost sheet member S1 of the stacked body PS, assuming that another sheet member S is in close contact with the sheet member S1, the other sheet member S is shaken off. Perform the operation. Specifically, the control unit 210 controls the lift cylinder 62 on the first suction unit 20 side and the lift cylinder 162 on the second suction unit 120 side to operate not at the same timing but at different timings. . Hereinafter, such a swing-off operation (a first operation example and a second operation example) will be described.

(3-1) First Operation Example of Swing-Down Operation FIG. 8 shows a first operation example of operation timing of the lifting cylinder 62 on the first suction unit 20 side and the lifting cylinder 162 on the second suction unit 120 side. FIG. As shown in FIG. 8, the control unit 210 first operates the lifting / lowering cylinder 62 so as to raise the suction holding unit 30 on the first suction unit 20 side, but at the same timing, the suction holding on the second suction unit 120 side. The operation of the lifting cylinder 162 is stopped without raising the unit 130. This image is shown in FIG. Then, when the suction holding unit 30 on the first suction unit 20 side is lifted, the sheet-like member S1 is inclined. For this reason, it becomes easy for air to enter between the other sheet members S that are in close contact with the sheet member S1, and most of the other sheet members S fall from the sheet member S1.

  Next, as shown in FIGS. 8 and 10, before and after raising the suction holding unit 30 on the first suction unit 20 side to the predetermined position, the control unit 210 performs suction holding on the second suction unit 120 side. The lifting cylinder 162 is operated so as to raise the section 130 to the prescribed position. Then, the suction holding unit 30 on the first suction unit 20 side and the suction holding unit 130 on the second suction unit 120 side are both in a raised state.

  Next, the control section 210 controls the lifting cylinder 62 on the first suction unit 20 side and the lifting cylinder 162 on the second suction unit 120 side to operate again at different timings. Specifically, as shown in FIG. 8 and FIG. 11, the suction holding unit 30 on the first suction unit 20 side is lowered to a specified position while the suction holding unit 130 on the second suction unit 120 side is kept raised. At this time, the sheet-like member S1 is inclined obliquely so that the suction holding unit 30 side of the first suction unit 20 is located on the lower side (Z2 side). In this state, the next sheet-shaped member S2 is not in contact with the next sheet-shaped member S2 and has an interval.

  Next, as shown in FIGS. 8 and 12, the control unit 210 adjusts the suction holding unit 30 on the first suction unit 20 side before and after lowering the suction holding unit 30 on the first suction unit 20 to the specified position. The lifting cylinder 162 is operated so as to lower the suction holding unit 130 on the second suction unit 120 side to the specified position while maintaining the state where the unit 30 is lowered. At this time, in addition to the first suction unit 20 side of the sheet-shaped member S1, the second suction unit 120 side of the sheet-shaped member S1 is also in a state in which the sheet-shaped member S1 has an interval without contacting the next sheet-shaped member S2. ing.

  Next, as shown in FIGS. 8 and 9, before and after lowering the suction holding unit 130 on the second suction unit 120 side to the specified position, the control unit 210 again performs suction on the first suction unit 20 side. The elevating cylinder 62 is operated so as to raise the holding unit 30, but at the same timing, the operation of the elevating cylinder 162 is stopped without raising the suction holding unit 130 on the second suction unit 120 side.

  Next, as shown in FIGS. 8 and 10, before and after raising the suction holding unit 30 on the first suction unit 20 side to the predetermined position, the control unit 210 performs suction holding on the second suction unit 120 side. The elevating cylinder 162 is operated so as to raise the part 130 again to the prescribed position. Then, the suction holding unit 30 on the first suction unit 20 side and the suction holding unit 130 on the second suction unit 120 side are both in a raised state. As a result, a large gap is formed between the sheet-shaped member S1 that is held by suction and the next sheet-shaped member S2. In addition, by repeatedly raising and lowering the first suction unit 20 and the second suction unit 120 as described above, more air enters between the sheet member S1 and another sheet member S in close contact with the sheet member S1. It becomes easier, and another sheet-like member S falls from the sheet-like member S1.

  Thereafter, the process proceeds to a fourth step described later. However, in order to drop another sheet-shaped member S from the sheet-shaped member S1 more reliably, the swing-down operation based on FIG. 8 may be repeated again.

(3-2) Second Operation Example of Swing-Down Operation Next, a second operation example of the swing-down operation will be described. FIG. 13 is a diagram illustrating a second operation example of the operation timing of the lifting cylinder 62 on the first suction unit 20 side and the lifting cylinder 162 on the second suction unit 120 side. As shown in FIG. 13, first, the lifting cylinder 62 is operated so as to raise the suction holding unit 30 on the first suction unit 20 side to the prescribed position, but at the same timing, the suction holding unit 130 on the second suction unit 120 side. , The operation of the lifting cylinder 162 is stopped. This image is the same as that already shown in FIG. 9, and when the suction holding unit 30 on the first suction unit 20 side is raised, the sheet-like member S1 is inclined. For this reason, it becomes easy for air to enter between the other sheet members S that are in close contact with the sheet member S1, and most of the other sheet members S fall from the sheet member S1.

  Next, as shown in FIGS. 13 and 14, the control unit 210 raises the suction holding unit 130 on the second suction unit 120 side to a prescribed position, and then moves the suction holding unit 130 on the second suction unit 120 side. Is moved down to the prescribed position, but at the same timing, the operation of the lifting cylinder 62 is stopped without lowering the suction holding unit 30 on the first suction unit 20 side. Then, the suction holding unit 130 that has reached the top of the ascent is lowered again, so that the sheet-like member S1 is in a state similar to the fluttered state, and the other sheets closely contacting the sheet-like member S1 It becomes easier for air to enter the space between the first and second members S. Thereby, many of the other sheet members S fall from the sheet member S1. When the suction holding unit 130 on the second suction unit 120 side is lowered to the specified position, the second suction unit 120 side of the sheet member S1 does not contact the next sheet member S2. It is in a state having an interval.

  Further, as shown in FIGS. 13 and 12, before and after lowering the suction holding unit 130 on the second suction unit 120 to the specified position, the control unit 210 controls the suction holding unit on the first suction unit 20 side. The elevating cylinder 62 is operated so as to lower the 30 to the specified position. At the same timing, the operation of the elevating cylinder 162 is stopped without raising the suction holding unit 130 on the second suction unit 120 side. At this time, in addition to the second suction unit 120 side of the sheet-like member S1, the first suction unit 20 side of the sheet-like member S1 is in a state in which the sheet-like member S1 has an interval without being in contact with the next sheet-like member S2. ing.

  Next, as shown in FIGS. 13 and 11, before and after lowering the suction holding unit 30 on the first suction unit 20 to the specified position, the control unit 210 controls the suction holding on the second suction unit 120 side. The elevating cylinder 162 is operated so as to raise the unit 130, but at the same timing, the operation of the elevating cylinder 62 is stopped without raising the suction holding unit 30 on the first suction unit 20 side.

  Next, as shown in FIGS. 13 and 10, the control unit 210 moves the suction holding unit 30 on the first suction unit 20 side again to the specified position while keeping the suction holding unit 130 on the second suction unit 120 raised. The raising / lowering cylinder 162 is operated so as to raise the height. Then, the suction holding unit 30 on the first suction unit 20 side and the suction holding unit 130 on the second suction unit 120 side are both in a raised state. As a result, a large gap is formed between the sheet-shaped member S1 that is held by suction and the next sheet-shaped member S2. In addition, by repeatedly raising and lowering the first suction unit 20 and the second suction unit 120 as described above, more air enters between the sheet member S1 and another sheet member S in close contact with the sheet member S1. It becomes easier, and another sheet-like member S falls from the sheet-like member S1.

  Thereafter, the process proceeds to a fourth step described later. However, in order to drop another sheet-like member S from the sheet-like member S1 more reliably, the swing-down operation based on FIG. 13 may be repeated again.

  The control for operating the lifting cylinder 62 on the first suction unit 20 side and the lifting cylinder 162 on the second suction unit 120 side at different timings, not at the same timing, is not limited to the above. . That is, as long as the other sheet-like member S in close contact with the uppermost sheet-like member S1 can be dropped well, the lifting cylinder 62 on the first suction unit 20 side and the second suction unit 120 The timing of the operation of the lifting cylinder 162 on the side may be any timing.

(4) Fourth step: Insertion of separation plate 71 (fourth control)
Next, as illustrated in FIG. 15, the control unit 210 includes the sheet-like member S <b> 1 sucked and held (lifted) by the suction holding units 30 and 130 and the uppermost sheet-like member of the remaining stacked body PS. During S2, the separation plate actuator 74 is operated so as to insert the separation plate 71.

(5) Fifth step: Release of suction holding of uppermost sheet-shaped member S1 (fifth control)
Next, the control unit 210 operates the mounting table cylinder 203 so as to raise the mounting table 201. At the same time, the control unit 210 stops the operations of the suction pump 51 on the first suction unit 20 side and the suction pump 151 on the second suction unit 120 side, and releases the suction holding of the uppermost sheet-shaped member S1. . At this time, the lifting cylinders 62, 162 may be controlled so as to lower the suction holding units 30, 130.

  Then, as shown in FIG. 16, when the suction holding of the uppermost sheet-shaped member S1 is released, the uppermost sheet-shaped member S1 falls toward the sheet-shaped member S2 (the laminate PS). At this time, the separation plate 71 is sandwiched between the uppermost sheet-shaped member S1 and the sheet-shaped member S2. Since the separation plate 71 is formed of an elastically deformable member, it is possible to prevent the separation plate 71 from being damaged even if the separation plate 71 contacts the sheet-like members S1 and S2.

  After releasing the suction holding of the sheet-like member S1, the control unit 210 operates the rotation actuators 43, 143 to move the suction holding units 30, 130 to the retracted position (see FIG. 17). Thus, even if the suction bed 220 is lowered in the next step, it is possible to prevent the suction holding units 30, 130 from interfering with the suction bed 220.

(6) Sixth Step: Suction Holding of Top Sheet Member S1 by Suction Bed 220 Next, the control section 210 lowers the suction bed 220 while operating suction means and a moving mechanism (not shown). Then, the suction plate 221 is pressed against the stacked body PS, and the stacked body PS is sandwiched between the suction plate 221 and the mounting table 201. At this time, even if the uppermost sheet-like member S1 is warped, the pinching operation causes the uppermost sheet-like member S1 to be suction-held by the suction plate 221 in a state where the warp has been corrected. This is shown in FIG. In the state shown in FIG. 17, similarly to the state shown in FIG. 16, the separation plate 71 is sandwiched between the uppermost sheet member S1 and the sheet member S2.

  Here, if the suction plate 221 is pressed strongly, the separation plates 71 and 171 may be sandwiched between the stacked body PS and the suction plate 221, which may cause a dent. In order to prevent such dents, the suction bed 220 is provided with a suction blower (not shown), and the suction plate 221 is gradually lowered while suction is performed by the suction blower. Immediately before the suction plate 221 presses the uppermost sheet-shaped member S1 downward (Z2 side), it is preferable to perform suction so as to raise only the uppermost sheet-shaped member S1. The suction plate 221 is gradually lowered until the uppermost sheet-shaped member S1 is suction-held, and when the sheet-shaped member S1 is suction-held, the lowering of the suction plate 221 is stopped. Here, in order to determine whether or not the uppermost sheet-like member S1 has been suction-held, the suction bed 220 may be provided with a vacuum sensor not shown.

  If the sheet member S is warped, starting with the uppermost sheet member S1, if the suction plate 221 does not descend until the uppermost sheet member S1 becomes flat, the vacuum sensor will be at the maximum. It is not determined that the upper sheet-like member S1 has been sucked and held by the suction blower. In this case, the uppermost sheet-like member S1 is pushed flat to the extent that the uppermost sheet-like member S1 can be sucked by the suction blower. However, even if the uppermost sheet-like member S1 is sucked and held even when the uppermost sheet-like member S1 is pushed flat, the further pushing down of the uppermost sheet-like member S1 below (Z2 side) is stopped. Thus, it is possible to prevent dents as described above from occurring.

  After the uppermost sheet-like member S1 is sucked by the suction plate 221, a moving mechanism (not shown) is operated to raise the suction bed 220, and thereafter, the uppermost sheet-like member S1 is separated into a separate processing part. Conveyed to.

(7) Seventh step: Lowering of mounting table 201 (return to initial position)
Next, the control unit 210 operates the mounting table cylinder 203 so as to lower the mounting table 201, and moves the mounting table 201 to the initial position. Thereafter, the operations of the above-described first to seventh steps are repeated, and the sheet-shaped members S are sequentially taken out of the stacked body PS.

<Other control operations>
By the way, the operation for dropping another sheet member S on the first suction unit 20 side and the second suction unit 120 side as described above may be performed as follows. First, the first step (adsorption and holding of the uppermost sheet member S) similar to that described with reference to FIG. 6 is performed. Since this first step has already been described, its description is omitted.

  Next, as an operation that combines the second step (separation of the uppermost sheet-shaped member S1 from the laminate PS) and the third step (implementation of the swing-down operation), the following eighth to eleventh steps are performed. The operation is performed.

(8) Eighth step: lifting of the suction holding unit 30 on one side (X1 side) of the row of the first suction units 20 After the first step, for example, of the suction holding units 30 existing on the first suction unit 20 side The control unit 210 controls the operation of the elevating cylinder 62 so that the suction holding unit 30 located on one side (X1 side) of the row rises. This state is shown in FIG. Then, since the support shaft 41 is inclined, the height position of the suction holding unit 30 gradually decreases from one side (X1 side) of the suction holding unit 30 to the other side (X2 side). At this time, since the suction holding units 130 present on the second suction unit 120 side are arranged in a state in which the height positions are aligned, the sheet-shaped member S1 that is suction-held is not a flat shape but a back side (Y2 Side) is sucked and held in a twisted state.

  By performing such an operation of twisting the sheet-like member S1, air can easily enter between the sheet-like member S1 and another sheet-like member S that is in close contact with the sheet-like member S1, and the other sheet-like members Most of S falls from the sheet-like member S1.

(9) Ninth Step: Raising of Suction Holding Unit 30 on the Other Side (X2 Side) of Line of First Suction Units 20 Next, of the suction holding units 30 existing on the first suction unit 20 side, the other of the lines The control unit 210 controls the operation of the lifting cylinder 62 so that the suction holding unit 30 located on the side (X2 side) is raised. This state is shown in FIG. Then, the suction holding unit 30 on the first suction unit 20 side is in a state of being entirely raised. At this time, on the first suction unit 20 side, a gap is formed between the sheet-like member S1 that is suction-held and the next sheet-like member S2.

  At this time, the sheet-like member S1 returns from the twisted state, and the back side (Y2 side) is in a state of being entirely lifted. Even by performing such an operation, air can easily enter between the sheet-shaped members S1 and the other sheet-shaped members S that are in close contact with each other, and many of the other sheet-shaped members S fall from the sheet-shaped member S1.

(10) Tenth step: raising the suction holding unit 130 on one side (X1 side) of the row of the second suction units 120 Next, one of the suction holding units 130 existing on the second suction unit 120 side The control unit 210 controls the operation of the lifting cylinder 162 so that the suction holding unit 130 located on the side (X1 side) is raised. This state is shown in FIG. Then, since the support shaft 141 is inclined, the height position of the suction holding unit 130 gradually decreases from one side (X1 side) of the suction holding unit 130 to the other side (X2 side). At this time, since the plurality of suction holding units 30 on the first suction unit 20 side have already risen so as to have the same height, the sheet-shaped member S1 that is suction-held is not a flat shape but a front side ( (Y1 side) is held by suction so as to be twisted.

  By performing such an operation of twisting the sheet-like member S1, it becomes easier for air to enter between the sheet-like member S1 and another sheet-like member S that is in close contact with the sheet-like member S1. Many of the members S fall from the sheet-like member S1.

(11) Eleventh step: lifting of suction holding section 130 on the other side (X2 side) of the row of second suction units 120 Next, the other of the suction holding sections 130 present on the second suction unit 120 side The control unit 210 controls the operation of the lifting cylinder 162 so that the suction holding unit 130 located on the side (X2 side) is raised. This state is shown in FIG. Then, the suction holding unit 130 on the second suction unit 120 side is in a state of being entirely raised. At this time, the suction holding section 30 on the first suction unit 20 side has already been entirely raised. Therefore, a gap (space) in a substantially parallel state is formed between the sheet-like member S1 held by suction and the next sheet-like member S2.

  At this time, the sheet-like member S1 returns from the twisted state, and the back side (Y2 side) is in a state of being entirely lifted. By performing such an operation, air can easily enter between the sheet-shaped member S1 and another sheet-shaped member S that is in close contact with the sheet-shaped member S1, and the other sheet-shaped member S falls from the sheet-shaped member S1.

  Through the operations of the eighth step to the eleventh step, air easily enters between the sheet member S1 and the other sheet member S that is in close contact with the sheet member S1, and the air adheres easily to the sheet member S1. The other sheet-shaped member S that has been dropped falls.

  After the eleventh step, as described above, the fourth step (insertion of the separation plate 71), the fifth step (release of the suction holding of the uppermost sheet member S1), and the sixth step (the suction bed 220). , And the seventh step (the lowering of the mounting table 201 (returning to the initial position)).

  In addition, after each of the above-described steps, by performing each of the steps for manufacturing the flexible printed board, a flexible printed board as a product is manufactured.

<About the effect>
The sheet take-out device 10 configured as above takes out the sheet-like member S used for manufacturing the flexible printed circuit board, and the suction holding unit 30 (which can hold one edge side of the sheet-like member S by suction). A first suction unit), a suction holding unit 130 (second suction unit) capable of holding the other edge of the sheet-shaped member S by suction, and an elevating mechanism 60 for moving the suction holding unit 30 (first suction unit) up and down. (First lifting / lowering means), a lifting / lowering mechanism 160 (second lifting / lowering means) for raising / lowering the suction holding unit 130 (second suctioning means), a lifting / lowering mechanism 60 (first lifting / lowering means), and a lifting / lowering mechanism 160 (second lifting / lowering means) And a control unit 210 (control means) for controlling the operation of (1).

  Further, the control section 210 (control means) moves the sheet member S1 stacked at the top from the stacked body PS on which the plurality of sheet members S are stacked to the suction holding section 30 (first suction means) and First control is performed to control the operation of the elevating mechanism 60 (first elevating means) and the elevating mechanism 160 (second elevating means) so that the suction holding unit 130 (second suction means) sucks and holds the first control. After that, one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) is moved up and down relatively to one of the other, so as to move up and down. By controlling the operation of at least one of the first lifting / lowering means) and the lifting / lowering mechanism 160 (second lifting / lowering means), the second control for swinging down the sheet-shaped member S other than the suction-held member is performed.

  For this reason, after the uppermost sheet-shaped member S1 is suction-held by the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) by the first control, the second control is performed. Thus, after the first control, one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) is moved up and down relatively to the other. Then, the air easily enters the space between the other sheet-like member S that is in close contact with the suction-held sheet-like member S1, and most of the other sheet-like members S fall from the sheet-like member S1. Therefore, it is possible to prevent a plurality of sheet members S from being taken out.

  Further, in order to prevent such a plurality of sheet-shaped members S from being taken out, at present, the sheet-shaped members S are taken out manually. , The sheet member S can be automatically taken out. Therefore, a human error in taking out the sheet-shaped member S can be prevented, and the productivity of the flexible printed circuit board can be improved by performing the automatic taking-out.

  The operation for preventing the removal of the plurality of sheet-shaped members S is performed by the relative operation between the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit). Since the sheet-like member S is realized by the elevating operation, a state in which no distortion occurs in the sheet-like member S can be achieved.

  Further, in the present embodiment, after the above-described first control, control section 210 (control section) is suction-held by suction holding section 30 (first suction section) and suction holding section 130 (second suction section). The third control for controlling the operation of the lifting mechanism 60 (first lifting means) and the lifting mechanism 160 (second lifting means) is performed so as to move the sheet-shaped member S separated from the stacked body PS. After the third control, the second control is performed.

  For this reason, even if the sheet-shaped member S is deformed like a warp, a space for dropping another sheet-shaped member S that is in close contact with the sheet-shaped member S1 can be secured. Further, a sufficient space for performing a relative elevating operation between the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) can be secured, and the sheet-like member S1 The other sheet-like member S that is in close contact with the sheet can be satisfactorily dropped.

  Further, in the present embodiment, the elevating mechanism 60 (first elevating means) includes an elevating cylinder 62 (one-side first elevating means) for elevating one side in the longitudinal direction of the suction holding unit 30 (first suction means). And an elevating cylinder 62 (the other first elevating means) for elevating the other side in the longitudinal direction of the suction holding section 30 (the first suction means). The elevating mechanism 160 (second elevating means) includes an elevating cylinder 162 (one-side second elevating means) for elevating and lowering one side in the longitudinal direction of the suction holding part 130 (second suction means), and the suction holding part 130 ( A lifting cylinder 162 (the other second lifting means) for raising and lowering the other side in the longitudinal direction of the second suction means). In the second control, the control unit 210 (control unit) operates the lifting cylinder 62 (one-side first lifting unit) so as to raise one side in the longitudinal direction of the suction holding unit 30 (first suction unit). After the start of the operation, the operation of the elevating cylinder 62 (the other-side first elevating means) is controlled so that the other side in the longitudinal direction of the adsorbing and holding unit 30 (the first suction means) is raised. The operation of the lifting / lowering cylinder 162 (one-side second lifting / lowering means) is controlled so as to raise one side in the longitudinal direction of the section 130 (second suction means), and after the start of the operation, the suction holding section 130 (the second suction means) The operation of the elevating cylinder 162 (the other-side second elevating means) is controlled so as to raise the other side in the longitudinal direction of (1).

  Therefore, the suction holding unit 30 (first suction unit) located on the other side (X2 side) in the longitudinal direction (X direction) is located on one side (X1 side) in the longitudinal direction (X direction). Since the holding portion 30 (first suction means) is raised, an operation of twisting the sheet-like member S1 is performed as shown in FIG. Further, the suction holding unit 130 (second suction unit) located on the other side (X2 side) in the longitudinal direction (X direction) is located on one side (X1 side) in the longitudinal direction (X direction). Since the part 30 (second suction means) is raised, an operation of twisting the sheet-like member S1 is performed as shown in FIG. By performing such an operation, it becomes easier for air to enter between the other sheet members S that are in close contact with the sheet member S1, and most of the other sheet members S fall from the sheet member S1. . Therefore, it is possible to satisfactorily prevent a plurality of sheet-shaped members S from being taken out.

  In the present embodiment, in the above-described second control, a direction in which one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) is separated from the stacked body PS. And the lifting / lowering mechanism 60 (first lifting / lowering means) so that one of the suction holding section 30 (first suction means) and the suction holding section 130 (second suction means) is not moved. And controls the operation of the lifting mechanism 160 (second lifting means) and, after the start of the operation, any one of the suction holding section 30 (first suction means) and the suction holding section 130 (second suction means) Is lifted and lowered so as to move the remaining one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) away from the stacked body PS while keeping the device from moving. Mechanism 60 (first ascent It controls the operation of the unit) and the lifting mechanism 160 (second lift means).

  For this reason, as shown in FIGS. 8 and 13, one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) is moved up and down with the other as a fulcrum. Therefore, air easily enters between the sheet-shaped member S1 and another sheet-shaped member S that is in close contact with the sheet-shaped member S1. Thereby, another sheet-shaped member S can be satisfactorily dropped from the uppermost sheet-shaped member S1, and the removal of a plurality of sheet-shaped members S can be satisfactorily prevented.

  Further, in the present embodiment, the sheet take-out device 10 includes a separation plate 71 (separation unit) that is inserted between the adjacent sheet members S to prevent suction between the sheet members S, A separating plate actuator 74 (moving means) for moving the separating plate 71 (separating means) so that the separating plate 71 (separating means) is inserted between the adjacent sheet members S is provided. The control section 210 (control means) controls the operation of the separation plate actuator 74 (moving means), and the control section 210 (control means) performs the suction holding section 30 (first control) after the third control described above. A separating plate 71 (separating means) is arranged between the sheet-like member S1 held by the suction unit and the suction holding unit 130 (second suction means) and the uppermost sheet-like member S2 of the laminate PS. A fourth control for controlling the operation of the separation plate actuator 74 (moving means) is performed.

  For this reason, the holding of the sheet-like member S1 held by the suction holding unit 30 and the suction holding unit 130 (the first suction unit and the second suction unit) is released, and the sheet-like member S1 is moved to the end of the laminate PS. When the sheet drops toward the upper sheet-like member S2, the separation plate 71 is sandwiched between the sheet-like member S1 and the sheet-like member S2. Therefore, it is possible to prevent the sheet-shaped member S1 and the sheet-shaped member S2 from coming into close contact with each other again, and to satisfactorily separate the sheet-shaped member S1 and the sheet-shaped member S2.

  Further, in the present embodiment, the sheet take-out device 10 includes a suction bed 220 that can suction-hold the sheet-shaped member S in a planar shape and can move up and down with respect to the stacked body PS. The operation is controlled by 210 (control means). After the above-described fourth control, the control unit 210 (control unit) holds the sheet-like member held by the suction holding unit 30 and the suction holding unit 130 (first suction unit and second suction unit). The operation of the suction mechanism 50 (the first suction means) and the operation of the suction mechanism 150 (the second suction means) are controlled so as to cancel, and the fifth control for overlapping the sheet-like member S1 on the laminate PS is performed. After the fifth control, the control unit 210 (control means) lowers the suction bed 220 so as to press the laminate PS (laminate), and sucks the uppermost sheet member S1 of the laminate PS. The operation of the adsorption bed 220 is controlled so as to hold it.

  Therefore, as shown in FIG. 17, the stacked body PS is sandwiched between the suction plate 221 and the mounting table 201 by the operation of pressing the stacked body PS due to the lowering of the suction bed 220. Thus, even if the uppermost sheet member S1 is warped, the pinching operation allows the uppermost sheet member S1 to correct the warp. Therefore, the uppermost sheet-shaped member S1 can be suction-held by the suction bed 220 in a planar state. Thus, accurate positioning of the sheet-like member S1 can be performed in a process after manufacturing the flexible printed circuit board.

  Further, in the present embodiment, the suction holding unit 30 and the suction holding unit 130 (the first suction unit and the second suction unit) use the elastic pads made of the elastic member and the suction pads 31 and 131 provided in a bellows shape. Have. Therefore, the suction pad 31 can easily change following the sheet-shaped member S, so that even if the sheet-shaped member S is deformed such as warpage, the deformation can be followed. For this reason, even if the suction pad 31 abuts on the sheet member S, it is possible to prevent the sheet member S from being damaged.

  Further, in the method of manufacturing a flexible printed board according to the present embodiment, the sheet holding member S1 stacked at the uppermost position from the stacked body PS is attached to one edge side of the sheet holding member S1 by suction. 30 (first suction means), the lifting mechanism 60 (first lifting means) so that the other edge side of the sheet-shaped member S1 is suction-held by the suction holding section 130 (second suction means) capable of suction-holding, and A suction step for controlling the operation of the lifting mechanism 160 (second lifting means), and after the suction step, any one of the suction holding section 30 (first suction means) and the suction holding section 130 (second suction means) The lifting mechanism 60 (first lifting / lowering unit) and the suction holding unit 130 (second suction unit) for raising / lowering the suction / holding unit 30 (first suction unit) so as to raise / lower one relative to the other. Ascending and descending By actuating at least one of the mechanism 160 (second lifting means), and a step shaken for dropping waving sheet member S other than that it sucked and held.

  For this reason, after the uppermost sheet-like member S1 is suction-held by the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) in the suction step, the swing-down step is performed. By moving one of the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit) up and down relatively to the other, the sheet-shaped suction-held sheet is held. The air easily enters the space between the other sheet-shaped members S that are in close contact with the member S1, and most of the other sheet-shaped members S fall from the sheet-shaped member S1. Therefore, it is possible to prevent a plurality of sheet members S from being taken out.

  Further, in order to prevent such a plurality of sheet-shaped members S from being taken out, at present, the sheet-shaped members S are taken out manually. , The sheet member S can be automatically taken out. Therefore, a human error in taking out the sheet-shaped member S can be prevented, and the productivity of the flexible printed circuit board can be improved by performing the automatic taking-out.

  The operation for preventing the removal of the plurality of sheet-shaped members S is performed by the relative operation between the suction holding unit 30 (first suction unit) and the suction holding unit 130 (second suction unit). Since the sheet-like member S is realized by the elevating operation, a state in which no distortion occurs in the sheet-like member S can be achieved.

<Modification>
As mentioned above, although one Embodiment of this invention was described, this invention can be variously deformed besides this. Hereinafter, this will be described.

  In the above-described embodiment, the suction and holding unit 30 and the suction mechanism 50 correspond to the first suction unit, and the suction and holding unit 130 and the suction mechanism 150 correspond to the second suction unit. However, the correspondence may be reversed. That is, the first suction unit may correspond to the suction holding unit 130 and the suction mechanism 150, and the second suction unit may correspond to the suction holding unit 30 and the suction mechanism 50. Similarly, the lifting mechanism 160 may correspond to the first lifting means, and the lifting mechanism 60 may correspond to the second lifting means.

  In the above-described embodiment, the suction pads 31 are provided in a bellows shape. However, the suction pad 31 is not limited to such a configuration, and may have another configuration such as a rubber tube having a predetermined length and suction holes provided at a predetermined pitch.

  Further, the sheet take-out device 10 according to the above-described embodiment may further include a separate configuration. For example, an ionizer (static elimination blower) may be provided in response to the case where the sheet-like members S are attracted by static electricity, and the charged static electricity may be blown from the ionizer to remove the static electricity. .

  In each of the above-described control operations, after a certain control operation is completed, the next control operation may be started.However, at the same time as the completion of a certain control operation or before the certain control operation is completed, The next control operation may be started.

  Further, the sheet-shaped member S in the above-described embodiment may be a single-sided copper foil material in which copper foil is present only on one side of a substrate such as a polyimide film, or a double-sided copper foil material in which copper foil is present on both sides of a substrate. It may be a foil material, or a multilayer material having a multilayer copper foil more than a double-sided copper foil material. Further, the sheet-shaped member S may include an adhesive layer and a release film for protecting the adhesive layer in addition to the base material and the copper foil. When such an adhesive layer or a release film is provided, the thickness of the sheet-shaped member S becomes larger than when not provided. For this reason, even when the sheet-shaped member S is warped, a dent is more unlikely to occur when the suction plate 221 is lowered to suction-hold the uppermost sheet-shaped member S1.
