  By the way, when manufacturing a plurality of member pieces using a plurality of dies having different processing shapes, for the purpose of improving the yield, a plurality of processing positions for each shape and a rotation angle of the mold at each processing position are set. It is possible to create a set complex arrangement pattern.

  However, an apparatus in which a plurality of molds are fixed as in Patent Document 1 cannot be used to perform press processing without omission according to the arrangement pattern by actually using such a complicated arrangement pattern for manufacturing. In addition, a method of adjusting the position of the mold and the array pattern by moving the coil material not only in one direction but also in the reverse direction and the width direction is also conceivable. However, there is a concern that the manufacturing efficiency is reduced by such a method. is there.

  Therefore, the present invention has been made in view of such a point, and the object of the present invention is to improve the yield while suppressing a decrease in manufacturing efficiency by feeding the coil material in one direction without returning it back. The blanking system and the manufacturing method of a member piece which can carry out the outline extraction of the member piece of two or more shapes from a coil material according to the complicated arrangement pattern mentioned above.

  (1) The blanking system of the present invention is for extruding a plurality of member pieces by pressing a coil material that is intermittently fed in one direction, and includes a first die set and a second die set. A die set, a material feeding mechanism, an array pattern storage unit, a movable range storage unit, and an operation control unit are provided.

  The first die set has a first die for pressing a first shape on the coil material, and is positioned in the X direction within a predetermined movable range in the X direction perpendicular to the longitudinal direction of the coil material. The position can be adjusted in the Y direction within a predetermined movable range in the Y direction parallel to the longitudinal direction, and the first mold can be rotated about its axis.

  The second die set has a second die for pressing a second shape different from the first shape on the coil material, and the position adjustment in the X direction can be performed within a predetermined movable range in the X direction. The second mold can be rotated around its axis.

  The material feeding mechanism intermittently feeds the coil material to the downstream side which is one of the Y direction with respect to the first die set and the second die set.

  The array pattern storage unit includes a plurality of first processing positions in the coil material pressed by the first mold and a plurality of the coil materials pressed by the second mold. Are sequentially arranged toward the upstream side in the Y direction within the range of the width in the X direction and the length in the Y direction of the coil material, and at the first processing position, A rotation angle is determined in advance, and an array pattern in which the rotation angle of the second mold is determined in each second processing position is stored.

  The movable range storage unit includes a first lower limit that is a movable limit to the downstream side of the first die set in the Y direction, and a second lower limit that is a movable limit to the downstream side of the second die set in the Y direction. Remember.

  The operation control unit controls the feeding mechanism based on the arrangement pattern to adjust the feeding length to send the coil material to the downstream side with respect to the first die set and the second die set, The first die set is controlled to adjust the position in the X direction, the position in the Y direction, and the rotation angle of the first mold, and the second die set is controlled to adjust the position in the X direction and the first position. 2 After adjusting the rotation angle of the mold, the coil material is pressed by controlling the first die set and the second die set.

  And the said operation control part is still press-worked in the distance between the 1st process position most downstream located in the most downstream among the 1st process positions which are not yet press-worked, and the said 1st minimum. Compare the distance between the second downstream position on the most downstream side and the second lower limit among the second machining positions that are not present, and preferentially press the machining position with the smaller distance. And

  In this configuration, the first die set can be adjusted in the X direction within a predetermined movable range in the X direction, and can be adjusted in the Y direction within a predetermined movable range in the Y direction. The mold is pivotable about its axis. Further, the second die set can be adjusted in the X direction within a predetermined movable range in the X direction, and the second mold can be rotated around its axis. Therefore, the position of the corresponding mold can be adapted to the various machining positions defined in the arrangement pattern and the rotation angle of the mold at the machining position, and the rotation angle can be adapted.

  Moreover, in this configuration, among the plurality of machining positions defined in the arrangement pattern, the distance between the most downstream first machining position and the first lower limit, the most downstream second machining position, and the The distance between the second lower limit and the second lower limit is compared, and the machining position with the smaller distance is preferentially subjected to press working. In this way, the machining position having a small distance from the lower limit of the movable range of the die set, that is, the machining position that should be given the highest priority, is always subject to pressing, so the coil material is fed in one direction without reversing. However, it is possible to prevent a processing position from passing through the die set without being pressed.

  In view of the above, in this configuration, the coil material is sent in one direction without reversing, and the reduction of the manufacturing efficiency is suppressed, and the member having a plurality of shapes from the coil material according to the complicated arrangement pattern for the purpose of improving the yield. The piece can be trimmed.

  (2) In the blanking system, it is preferable that the second die set can be adjusted in the Y direction within a predetermined movable range in the Y direction.

  In this configuration, since the position adjustment in the Y direction can be performed not only for the first die set but also for the second die set, it is possible to deal with more complicated arrangement patterns.

  (3) The blanking system preferably further includes a processing position storage unit, a die set selection unit, a die set storage unit, and a feed length determination unit. In this case, each unit is as follows. To work.

  The processing position storage unit stores whether or not press processing has been performed for each first processing position and each second processing position. The die set selection unit selects whether or not to use the first die set and the second die set for the next press work. The die set storage unit stores a selection result in the die set selection unit. The feed length determination unit is such that the most downstream first machining position is located upstream from the first lower limit, and the most downstream second machining position is located upstream from the second lower limit, And the feed material mechanism feeds the coil material to the downstream side so that at least one of the most downstream first machining position and the most downstream second machining position is located within the movable range of the corresponding die set. Decide the length.

  When it is assumed that the coil material moves downstream by an amount corresponding to the feed length determined by the feed length determination unit, the die set selection unit and the first processing position on the most downstream side and the first The distance between the lower limit and the distance between the second downstream processing position and the second lower limit are compared, and the die set with the smaller distance is selected and stored in the die set storage unit. . The die set selection unit adjusts the position of the selected die set to the most downstream processing position corresponding to the selected die set by the operation control unit, and the other unselected die set corresponds to the highest die set. Assuming that the position is adjusted by the motion control unit at the downstream processing position, if these die sets do not interfere with each other, the other die set is stored in the die set storage unit and the die sets interfere with each other. When doing so, the other die set is not stored in the die set storage unit.

  The operation control unit controls the die set stored in the die set storage unit to adjust the position in the X direction, the position in the Y direction, and the rotation angle, and presses the coil material by the die set. Process.

  In this configuration, in the former assumption, the die set selection unit has a distance between the most downstream first machining position and the first lower limit, and a distance between the most downstream second machining position and the second lower limit. Are compared, and the die set with the smaller distance is selected and stored in the die set storage unit. In a system in which the coil material is fed in one direction, the coil material cannot be returned to the upstream side, but a die set having a machining position with a smaller distance from the lower limit as in this configuration is preferentially used as a die set storage unit. And the operation control unit controls the die set stored in the die set storage unit, and the processing position can be surely pressed. Thereby, it can prevent that the process position which passes a die set, without being press-processed arises.

  Further, in this configuration, in the latter assumption, when the die sets do not interfere with each other, the die set selection unit stores the other die set in the die set storage unit, and when the die sets interfere with each other, The die set is not stored in the die set storage unit. By adopting such a configuration, the coil material can be pressed using both the first die set and the second die set when the die sets do not interfere with each other, and when the interference occurs, the coil material is preferentially selected. One die set is used for pressing while the other die set is not used for pressing. By determining the presence or absence of interference in this way, it is possible to perform press processing using as many die sets as possible, and thus the processing efficiency can be further improved.

  (4) It is preferable that the blanking system further includes a single pressurizing unit that pushes both the first mold and the second mold in the pressing direction. In this case, the first die set is movable to a retracted position where the first die is positioned outside the coil material in the X direction, and the second die set is formed by the second die set. A die set that is movable to a retreat position located outside the coil material in the X direction and that is not stored in the die set storage unit before the operation control unit pushes the pressurizing unit in the press direction. Is moved to the retracted position.

  In this configuration, when there is a die set that is not used for press working, a single pressurizing part is pushed in the pressing direction with the die set moved to the retracted position, and the coil material is pressed. Is given. On the other hand, when all the die sets are used for press working, a single pressurizing part is pushed in the pressing direction, so that the processing position corresponding to each die set is pressed. Therefore, it is not necessary to provide a pressurizing unit for each die set and control these pressurizing units individually, so that the structure and control of the system can be simplified.

  (5) In the blanking system, the first die set further includes a main plate supporting a first mold, and a position adjusting mechanism for adjusting a position in the X direction and a position in the Y direction on the main plate. The position adjusting mechanism includes a column and an arm having one end rotatably supported by the column and the other end rotatably supported by the main plate.

  (6) The method of this invention is a manufacturing method of the member piece which carries out the external shape extraction of the multiple-shaped member piece by pressing the coil material sent intermittently to one direction. In this manufacturing method, the coil material has a first mold for pressing the first shape, and the position adjustment in the X direction can be performed within a predetermined movable range in the X direction perpendicular to the longitudinal direction of the coil material. A first die set capable of adjusting the position in the Y direction within a predetermined movable range in the Y direction parallel to the longitudinal direction, the first die being rotatable about its axis, and the coil material A second mold for pressing a second shape different from the first shape, and the position of the second mold can be adjusted within a predetermined movable range in the X direction. A second die set rotatable about an axis, and a feeding material mechanism for intermittently sending the coil material to the downstream side which is one of the Y direction with respect to the first die set and the second die set; A plurality of the coil materials pressed by the first mold The first machining position and the plurality of second machining positions in the coil material pressed by the second die are within the range of the width in the X direction and the length in the Y direction in the coil material. The first mold is rotated in advance at each first processing position, and the second mold is rotated at each second processing position in advance. A blanking system including an array pattern storage unit that stores the array pattern thus obtained is used.

  This manufacturing method is a first processing position that is located on the most downstream side among the first processing positions that have not yet been pressed, and a first limit that is movable to the downstream side of the first die set in the Y direction. The distance between the lower limit, the second machining position that is located on the most downstream side of the second machining position that has not yet been pressed, and the movable limit to the downstream side of the second die set in the Y direction. Comparing a distance between a second lower limit and selecting a machining position with a smaller distance; and a die set corresponding to the machining position with the smaller distance selected in the selection step. Adjusting the rotation angle of the die of the die set, and preferentially pressing the processing position having the smaller distance.

  The first die set of the blanking system used in this method can be adjusted in the X direction within a predetermined movable range in the X direction, and can be adjusted in the Y direction within a predetermined movable range in the Y direction. In addition, the first mold can be rotated around its axis. Further, the second die set can be adjusted in the X direction within a predetermined movable range in the X direction, and the second mold can be rotated around its axis. Therefore, the position of the corresponding mold can be adapted to the various machining positions defined in the arrangement pattern and the rotation angle of the mold at the machining position, and the rotation angle can be adapted.

  Moreover, in this method, among the plurality of machining positions defined in the arrangement pattern, the distance between the most downstream first machining position and the first lower limit, the most downstream second machining position, and the The distance between the second lower limit and the distance is compared, and the machining position with the smaller distance is preferentially pressed. In this way, the machining position having a small distance from the lower limit of the movable range of the die set, that is, the machining position that should be given the highest priority, is always subject to pressing, so the coil material is fed in one direction without reversing. However, it is possible to prevent a processing position from passing through the die set without being pressed.

  In view of the above, in this method, the coil material is sent in one direction without reversing, and a reduction in manufacturing efficiency is suppressed, and a plurality of members are formed from the coil material in accordance with a complicated arrangement pattern for the purpose of improving yield. The piece can be trimmed.

  (7) In the manufacturing method, it is preferable that the second die set can be adjusted in the Y direction within a predetermined movable range in the Y direction.

  In this method, since the position adjustment in the Y direction can be performed not only for the first die set but also for the second die set, it is possible to deal with more complicated arrangement patterns.

  (8) In the manufacturing method, the position of the die set corresponding to the machining position with the smaller distance selected in the selection step is adjusted, and the machining position with the larger distance is adjusted to this. When it is assumed that the positions of the corresponding die sets are adjusted, it is preferable that a step of determining whether or not these die sets interfere with each other is further provided before the pressing step. In this case, in the pressing step, when it is determined in the determining step that the die sets do not interfere with each other, when both the processing positions are pressed and it is determined that the die sets interfere with each other. Moves the die set corresponding to the machining position with the larger distance to the retracted position.

  In this method, in the above assumption, the coil material can be pressed using both the first die set and the second die set when the die sets do not interfere with each other. The set is used for pressing while the other die set is not used for pressing. By determining the presence or absence of interference in this way, it is possible to perform press processing using as many die sets as possible, and thus the processing efficiency can be further improved.

  According to the present invention, a plurality of member pieces are externally formed from a coil material according to a complicated arrangement pattern for the purpose of improving the yield while suppressing a decrease in manufacturing efficiency by feeding the coil material in one direction without reversing. Can be removed.

  Hereinafter, a blanking system 1 according to an embodiment of the present invention will be described with reference to the drawings. This blanking system 1 is for pressing a coil material that is intermittently fed in one direction to remove the outer shape.

  As shown in FIGS. 1 to 4, the blanking system 1 includes an uncoiler 3 that unwinds (unwinds) the coil material 2 and sends it to the downstream side, and a pinch roller (not shown) Are provided with a leveler 4 that is stretched flat and fed out, a press mechanism 6, a controller 70 that controls these, and a housing 5 that covers the press mechanism 6. The uncoiler 3, the leveler 4 and the press mechanism 6 are arranged in this order in the feed direction of the coil material 2.

  In the present embodiment, the uncoiler 3 and the leveler 4 constitute a feed mechanism. The coil material 2 rewound by the feed mechanism is sent to a press mechanism 6 positioned downstream of the feed mechanism along the longitudinal direction.

  The press mechanism 6 includes a first die set 10, a second die set 20, a third die set 30, a fourth die set 40 and a fifth die set 50. The first to fifth die sets are different from each other in the shape and size of the mold, but the general configuration is the same. The first die set 10 will be described in detail with reference to FIGS. 1 to 5, and detailed description of the second to fifth die sets will be omitted.

  As shown in FIGS. 1 to 5, the first die set 10 includes a pair of main plates 13 that are opposed to each other in the vertical direction and extend in a substantially horizontal direction, the first mold 11 supported by these main plates 13, and a slide. It has a mechanism, an index 12 that can adjust the rotation angle of the first mold 11, and a position adjusting mechanism that adjusts the position in the X direction and the position in the Y direction.

  The pair of main plates 13 includes a lower main plate 13a and an upper main plate 13b. The lower main plate 13 a and the upper main plate 13 b have a rectangular shape in which the dimension in the X direction perpendicular to the longitudinal direction of the coil material 2 is larger than the dimension in the Y direction parallel to the longitudinal direction of the coil material 2.

  The first mold 11 presses the first shape of the coil material 2 (for example, the first shape B1 shown in FIG. 9). The first mold 11 includes a die 11a and a punch 11b. The die 11a and the punch 11b have a circular shape in plan view.

  The index 12 includes a lower index 12a for adjusting the rotation angle of the die 11a and an upper index 12b for adjusting the rotation angle of the punch 11b. The lower index 12a and the upper index 12b have a circular shape in plan view, and have a larger outer diameter than the die 11a and the punch 11b.

  The lower index 12a is disposed on the upper surface side of the lower main plate 13a, and is supported so as to be rotatable with respect to the lower main plate 13a. The lower index 12a is rotated by a motor (not shown) provided on the upper surface of the lower main plate 13a or the lower surface of the lower main plate 13a, for example. When the motor is provided on the upper surface of the lower main plate 13a, a configuration in which the rotation of the motor is transmitted to the lower index 12a by, for example, a worm gear can be exemplified. The rotation angle θ is controlled by numerical control (NC), for example. The die 11a is fixed to the lower index 12a. Therefore, when the lower index 12a is rotated by a predetermined angle θ by the motor, the die 11a is rotated by the same angle θ.

  The upper index 12b is disposed on the lower surface side of the upper main plate 13b and is supported to be rotatable with respect to the upper main plate 13b. The upper index 12b is rotated by a motor (not shown) provided on the lower surface of the upper main plate 13b or the upper surface of the upper main plate 13b, for example. When the motor is provided on the lower surface of the upper main plate 13b, a configuration in which the rotation of the motor is transmitted to the upper index 12b by, for example, a worm gear can be exemplified. The rotation angle θ is controlled by numerical control (NC), for example. The punch 11b is fixed to the upper index 12b. Therefore, when the upper index 12b is rotated by the predetermined angle θ by the motor, the punch 11b is rotated by the same angle θ.

  The position adjustment mechanism includes a pair of support columns 16, a first arm 17 (a pair of arms 17a and a pair of arms 17b), and a motor (not shown). Each column 16 has a lower end fixed to the ground and extends upward. One end of an arm 17a is rotatably supported on the upper end of each support column 16. The other end of each arm 17a is rotatably attached to one end of the arm 17b. As shown in FIG. 3, the other end of the arm 17b located on the right side in the feeding direction of the coil material 2 is rotatably attached to the right end of the lower main plate 13a in the X direction. The other end of the arm 17b located on the left side in the feeding direction of the coil material 2 is rotatably attached to the left end of the lower main plate 13a in the X direction.

  The arms 17a and 17b are driven so that the lower main plate 13a moves in the X direction or the Y direction while the lower main plate 13a maintains a posture parallel to the X direction.

  Since the first die set 10 has the position adjustment mechanism as described above, the position adjustment in the X direction is possible within a predetermined movable range in the X direction, and the Y direction is within the predetermined movable range in the Y direction. Can be adjusted. Specifically, when a motor (not shown) is operated, the position of the first die set 10 in the X direction and the position in the Y direction is adjusted while maintaining the posture in which the longitudinal direction of the pair of main plates 13 is parallel to the X direction. Is done. The movable range in the X direction and the movable range in the Y direction are stored in a movable range storage unit 73 described later. Further, the first die set 10 is movable to a retracted position where the first mold 11 is positioned outside the coil material 2 in the X direction (see, for example, FIG. 22 described later).

  The sliding mechanism is a mechanism for moving the lower main plate 13a and the upper main plate 13b in a direction parallel to each other while moving the upper main plate 13b in a direction approaching (lower) and a distance from the lower main plate 13a (upward). It is. The sliding mechanism includes four cylinders 14 fixed to the four corners of the upper surface of the lower main plate 13a, and four guide cylinders 15 fixed to the four corners of the lower surface of the upper main plate 13b. Each cylinder 14 is inserted through a guide tube 15 corresponding to the upper end portion thereof. At four corners of the upper main plate 13b, through holes 13c communicating with the corresponding guide cylinders 15 are provided.

  FIG. 5 shows a state in which the upper main plate 13b has moved in a direction away from the lower main plate 13a. When the press work by the first mold 11 is performed on the coil material 2, the upper main plate 13b moves in a direction approaching the lower main plate 13a, and the punch 11b is fitted into the die 11a. At this time, each cylinder 14 slides within the corresponding guide cylinder 15, and a portion on the upper end side of each cylinder 14 projects upward from the upper main plate 13b through the through hole 13c.

  As described above, the second to fifth die sets have the same configuration as that of the first die set 10, but main differences will be described below.

  First, the second die set 20 has a second die 21 for pressing the second shape on the coil material 2. The third die set 30 has a third die 31 for pressing the third shape on the coil material 2. The fourth die set 40 has a fourth die 41 for pressing the fourth shape on the coil material 2. The fifth die set 50 has a fifth die 51 for pressing the fifth shape on the coil material 2. The first to fifth shapes are different from each other.

  Next, the third die set 30 can be adjusted in position in the X direction, but is different from the other die sets in that the position in the Y direction is fixed. Specifically, the position adjustment mechanism of the third die set 30 has a pair of cylinder portions 37. Each cylinder portion 37 includes a cylinder tube 37a and a piston rod 37b. The cylinder tube 37a has a cylindrical shape, and a piston rod 37b is inserted therein.

  As shown in FIG. 3, the pair of cylinder portions 37 are arranged so as to sandwich the third die set 30 from both sides in a posture parallel to the longitudinal direction of the third die set 30. In FIG. 3, the tip of the piston rod 37b positioned on the right side in the feeding direction of the coil material 2 is fixed to the right end of the lower main plate 13a in the X direction. The tip of the piston rod 37b located on the left side in the feeding direction of the coil material 2 is fixed to the left end of the lower main plate 13a in the X direction.

  The piston rod 37b protrudes from the cylinder tube 37a along the axial direction by a driving source such as hydraulic pressure or a motor, or is accommodated in the cylinder tube 37a. As a result, the position of the third die set 30 in the X direction is adjusted.

  As described above, the first die set 10 has the support column 16 and the first arm 17 as the position adjustment mechanism. Similarly, the second die set has the support column 16 and the second arm as the position adjustment mechanism. 17, the fourth die set has a column 16 and a third arm 17 as a position adjustment mechanism, and the fifth die set has a column 16 and a second arm 17 as a position adjustment mechanism. Yes.

  1 to 4, the first arm 17, the second arm 17, the fourth arm 17, and the fifth arm 17 are arranged so as not to interfere with each other. Further, each arm 17 and the cylinder part 37 as the position adjusting mechanism of the third die set 30 are arranged so as not to interfere with each other.

  Specifically, the first arm 17 and the second arm 17 are displaced from each other in the height direction, and the fourth arm 17 and the fifth arm 17 are displaced from each other in the height direction. In the present embodiment, the second arm 17 is disposed at a higher position than the first arm 17, and the fourth arm 17 is disposed at a higher position than the fifth arm 17. Further, the second arm and the fourth arm are disposed at a position higher than the cylinder portion 37.

  As the position adjustment mechanism, for example, another mechanism such as an XY table can be employed. However, when the arm 17 is employed as the position adjustment mechanism, for example, the above-described position adjustment mechanism can be used as compared with other position adjustment mechanisms such as an XY table. Thus, since it can be set as the structure where die sets do not interfere easily, it becomes possible to arrange | position each die set in the state which brought die sets closer together.

  As shown in FIG. 4, the blanking system 1 further includes a single pressure unit 91 that pushes each upper main plate 13 b of the first to fifth die sets in the pressing direction (downward). The pressurizing unit 91 includes a pressurizing unit main body 91a having a size capable of covering part or all of the upper surface of each upper main plate 13b of the first to fifth die sets, and a motor (not shown). The pressurizing unit main body 91a has a rectangular shape in plan view and can be moved in the vertical direction by the motor.

  As shown in FIG. 6, the functions of the controller 70 include an operation control unit 71, an array pattern storage unit 72, a movable range storage unit 73, a processing position storage unit 74, a die set selection unit 75, a die set storage unit 76, a feed A length determination unit 77 and a most downstream processing position selection unit 78 are included. The controller 70 controls the first die set 10, the second die set 20, the third die set 30, the fourth die set 40, the fifth die set 50, the uncoiler 3 and the leveler 4.

  The array pattern storage unit 72 stores a predetermined array pattern (see, for example, FIG. 8 described later). The arrangement pattern includes a plurality of first machining positions pressed by the first mold 11 with respect to the coil material 2, a rotation angle of the first mold 11 at each first machining position, and the coil material 2. On the other hand, the second mold 21 is pressed by a plurality of second machining positions, the rotation angle of the second mold 21 at each second machining position, and the coil material 2 is pressed by the third mold 31. A plurality of third machining positions to be machined, a rotation angle of the third die 31 at each third machining position, and a plurality of fourth machining positions to be pressed by the fourth die 41 with respect to the coil material 2 The rotation angle of the fourth mold 41 at each fourth processing position, a plurality of fifth processing positions pressed by the fifth mold 51 with respect to the coil material 2, and the fifth processing position at each fifth processing position. The rotation angle of the five molds 51 is determined in advance.

  The operation control unit 71 controls the uncoiler 3 and the leveler 4 to adjust the feed length for sending the coil material 2 to the downstream side with respect to the first die set 10 and the second die set 20.

  Further, the operation control unit 71 adjusts the position of the first die set 10 in the X direction, the position of the Y direction, and the rotation angle of the first mold 11, and the position of the second die set 20 in the X direction, the Y direction. And the rotation angle of the second die 21 are adjusted, the position of the third die set 30 in the X direction and the rotation angle of the third die 31 are adjusted, and the position of the fourth die set 40 in the X direction is adjusted. The position in the Y direction and the rotation angle of the fourth mold 41 are adjusted, and the position in the X direction and the position in the Y direction of the fifth die set 50 and the rotation angle of the fifth mold 51 are adjusted.

  Thereafter, the operation control unit 71 controls the first to fifth die sets to press the coil material 2. Examples of the press working mechanism include a serve press that pressurizes by controlling the drive of the die set with a servo motor.

  The movable range storage unit 73 stores the movable range in the X direction and the movable range in the Y direction of each die set. Specifically, the first movable range in the Y direction of the first die set is a first lower limit that is a movable limit to the downstream side of the first die set 10 in the Y direction, and a movable range to the upstream side of the first die set. This is a range defined by the first upper limit that is the limit. The second movable range in the Y direction of the second die set, the fourth movable range in the Y direction of the fourth die set, and the fifth movable range in the Y direction of the fifth die set have the same configuration as the first movable range. Since there is, explanation is omitted. Further, in the present embodiment, since the third die set does not move in the Y direction, the movable range storage unit 73 is configured such that the range of the third die set in the Y direction (the position of the upstream end of the third die set in the Y direction). , The position of the Y direction downstream end). In the case where the third die set is also capable of adjusting the position in the Y direction in the same manner as other die sets, the movable range storage unit 73 stores the third movable range in the Y direction of the third die set. .

  As shown in FIG. 8 described later, the movable ranges of adjacent die sets partially overlap each other in the Y direction. However, since the position of the third die set 30 cannot be adjusted in the Y direction, the movable range of the second die set 20 does not overlap the range of the third die set 30 in the Y direction. The movable range of 40 does not overlap with the range of the third die set 30.

  The machining position storage unit 74 stores whether or not press machining has been performed for each first machining position, each second machining position, each third machining position, each fourth machining position, and each fifth machining position. The die set selection unit 75 selects whether to use the first die set 10, the second die set 20, the third die set 30, the fourth die set 40, and the fifth die set 50 for the next press working. To do. The die set storage unit 76 stores the selection result in the die set selection unit 75. The feed length determination unit 77 determines the feed length of the coil material 2 to the downstream side by the uncoiler 3 and the leveler 4. The die set selection unit 75 selects a die set to be pressed.

  Next, a control example of the blanking system 1 will be described. FIG. 7 is a flowchart illustrating a control example of the blanking system 1. In this control example, the blanking system 1 is controlled according to the flowchart shown in FIG. 7, so that press working is performed on the coil material 2 according to, for example, an arrangement pattern shown in FIG. 8 described later.

  First, the operation control unit 71 controls the feed mechanism (the uncoiler 3 and the leveler 4) to bring the origin of the coil material 2 (Y = 0) into the movable range in the Y direction of the most upstream die set (fifth die set 50). The coil material 2 is sent to the downstream side up to a position including (Step S1). In this control example, the origin of coordinates (X = 0, Y = 0) is set at the corner of the coil material 2.

  Next, the die set selection unit 75 resets the die set storage unit 76 and deletes the data stored in the die set storage unit 76 (step S2).

  Next, the most downstream machining position selection unit 78 is the most downstream first machining located on the most downstream side among the first machining positions that have not yet been pressed (the machining position that is pressed by the first die set 10). Similarly, the position is selected, and the second processing position on the most downstream side that is located on the most downstream side is selected from the second processing positions that are not yet pressed. The most downstream machining position selection unit 78 selects the third machining position, the fourth machining position, and the fifth machining position on the most downstream side in the same manner (step S3).

  Next, the feed length determination unit 77 has the most downstream first machining position positioned upstream from the first lower limit, and the most downstream second machining position positioned upstream from the second lower limit. The downstream third machining position is located upstream of the third lower limit, the most downstream fourth machining position is located upstream of the fourth lower limit, and the most downstream fifth machining position is less than the fifth lower limit. To the downstream side of the coil material 2 by the feed mechanism so that as many machining positions as possible are located within the movable range of the corresponding die set among the most downstream first to fifth machining positions. Is determined (step S4). At this time, the feed length is determined so that the corresponding machining position is included in the movable range of at least one die set.

  Next, when it is assumed that the coil material 2 moves to the downstream side by the feed length determined by the feed length determination unit 77, the die set selecting unit 75 and the first processing position on the most downstream side and the first The distance between the lower limit, the distance between the most downstream second machining position and the second lower limit, the distance between the most downstream third machining position and the third lower limit, and the most downstream fourth machining The distance between the position and the fourth lower limit is compared with the distance between the fifth downstream processing position and the fifth lower limit, and the die set having the shortest distance is selected and stored in the die set storage unit 76. (Step S5).

  Next, the die set selection unit 75 adjusts the position of the selected die set to the most downstream processing position corresponding to the selected die set by the operation control unit 71, and the other die set that is not selected corresponds to the most downstream processing position. When it is assumed that the position is adjusted by the motion control unit 71 at the processing position, if adjacent die sets do not interfere with each other (YES in step S6), another die set is stored in the die set storage unit 76 (step S7). ) When any of the die sets interfere with each other, the other die sets are not stored in the die set storage unit 76 (NO in step S6). Further, the die set storage unit 76 does not store a die set whose processing range is not included in the movable range when the feed length is determined in step S4.

  Next, the operation control unit 71 moves the die set that is not stored in the die set storage unit 76 to the retreat position (step S8).

  Next, with respect to the die set stored in the die set storage unit 76, the position in the X direction is moved to the corresponding machining position (step S9). In step S9, among the die sets stored in the die set storage unit 76, the die sets other than the third die set 30 are moved to the corresponding machining positions in the Y direction. Next, the rotation angle θ of the mold in each die set is adjusted (step S10).

  Next, the operation control unit 71 controls the uncoiler 3 and the leveler 4 to send the coil material 2 to the downstream side by the feed length determined by the feed length determination unit 77 (step S11). Thereafter, the operation control unit 71 controls the pressurizing unit 91 to push the upper main plates 13b of the first to fifth die sets downward to press the coil material 2 (step S12).

  Next, the processing position storage unit 74 stores that the processing position pressed in step S11 has been processed (step S13). When the unprocessed machining position remains, the operation control unit 71 returns to step S2 and repeats the above control (step S14). The general flow of the control example is as described above.

  FIG. 8 is a schematic diagram illustrating an example of an arrangement pattern stored in the arrangement pattern storage unit 72 and the arrangement of each die set. FIG. 9 shows a plurality of machining positions in each die set, a rotation angle θ at each machining position, a classification of whether or not press machining has been performed for each machining position, a movable range in the X direction and a movable range in the Y direction of each die set. FIG. 5 is a table showing processing selection data stored in the die set storage unit and a movement amount in the Y direction from the start position. FIG.

  In addition, in FIG. 9, although the combination of the shape shown to 1st shape B1-5th shape B5 is illustrated, it is not limited to this. In FIG. 8, the coil material 2 is drawn in a rectangular shape, but actually extends further upstream.

  The array patterns shown in FIGS. 8 and 9 include 17 first shapes B1, 11 second shapes B2, 12 third shapes B3, 11 fourth shapes B4, and 17 fifth shapes. B5 is arranged. This arrangement pattern is designed giving priority to the yield of the coil material 2. For example, this arrangement pattern is determined according to a nesting program programmed so as to obtain an arrangement with improved yield. Further, as shown in FIGS. 8 and 9, in this embodiment, the rotation angle θ is designed to take various values at the machining positions of the respective shapes. Thereby, the variation which arrange | positions each shape with respect to the coil material 2 increases.

  An example of the dimensions of the coil material 2 and each die set is as follows. In each die set, the center of the mold is located approximately in the middle in the X direction and approximately in the middle in the Y direction.

Coil material 2 width: 800 mm
First die set: 2000 mm length in the X direction, 150 mm length in the Y direction
Second die set: length in the X direction 2000 mm, length in the Y direction 250 mm
Third die set: length in the X direction 2000 mm, length in the Y direction 440 mm
Fourth die set: 2000 mm length in the X direction, 250 mm length in the Y direction
Fifth die set: 2000 mm length in the X direction, 150 mm length in the Y direction
An example of the movable range of each die set is as follows. That is, the first die set 10 has a movable range in the X direction of 0 to 950 mm, and a movable range in the Y direction is 500 mm. The second die set 20 has a movable range in the X direction of 0 to 1000 mm, and a movable range in the Y direction of 400 mm. The third die set 30 has a movable range in the X direction of 0 to 1150 mm and a movable range in the Y direction of 300 mm. The fourth die set 40 has a movable range in the X direction of 0 to 1000 mm, and a movable range in the Y direction is 400 mm. The fifth die set 50 has a movable range in the X direction of 0 to 950 mm and a movable range in the Y direction of 500 mm. Note that the movable range in the X direction is described with reference to the coordinates where the origin O is zero. Moreover, since the upper limit numerical value and the lower limit numerical value in the movable range in the Y direction change as the coil material 2 is sent to the downstream side, it is represented by the size of the movable range.

  In FIG. 9, the numerical values of X and Y at each processing position indicate the coordinates of points indicated by reference numerals b1 to b5 in FIG. In the case of this embodiment, the points b1 to b5 are positions corresponding to the centers C1 to C5 of the corresponding mold (the center in the case of a circular mold in plan view). Further, the rotation angle θ means an angle rotated clockwise in plan view when the orientation of each figure shown in FIG. 9 is used as a reference.

  Further, in the section of FIG. 9, the processing position described as “unfinished” means that the press processing is incomplete, and the processing position described as “completed” indicates that the press processing has been completed. (For example, refer to FIG. 11). In addition, the order of the plurality of machining positions of each shape in FIG. 9 is arranged in order from the smallest Y-axis value in the array pattern shown in FIG. 8 created by nesting processing. Further, the Y-axis movement amount in FIG. 9 indicates the cumulative distance that the coil material 2 has moved in the Y direction from the initial position (starting position of press working).

  FIG. 10 is a schematic diagram showing the state of the array pattern and the arrangement of each die set during the n-th press work in the blanking system 1. FIG. 11 is a table showing coordinate data and the like of each die set during the n-th press work shown in FIG.

  In FIG. 10, the processing positions drawn in white indicate that the press processing has been completed, and correspond to the description in the section column in FIG. The n-th press work will be described with reference to the flowchart of FIG. 7 again.

  In step S3, the most downstream machining position selection unit 78 selects the most downstream first machining position located on the most downstream side among the first machining positions that have not yet been pressed. The selected first downstream processing position is a processing position marked with a circle in FIG. Similarly, the most downstream machining positions are selected for the second to fifth machining positions (the machining positions marked with circles in FIG. 11).

  Then, when it is assumed that the coil material 2 moves downstream by the feed length determined by the feed length determination unit 77 in step S4, the die set selection unit 75 sets the most downstream first machining position ( Y-axis value: 110) and the first lower limit (−250) distance (360), the most downstream second machining position (380) and the second lower limit (100) distance (280), and the most downstream The distance (155) between the third machining position (700) and the third lower limit (545), the distance (300) between the fourth downstream machining position (1290) and the fourth lower limit (990), and the most downstream The distance (110) between the fifth machining position (1350) and the fifth lower limit (1240) is compared. In this case, the die set with the shortest distance is the fifth die set 50. Accordingly, in step S5, the fifth die set 50 is selected and stored in the die set storage unit 76.

  As described above, in step S4, the feed length determination unit 77 sends the feed length so that as many machining positions as possible among the most downstream first to fifth machining positions are located within the movable range of the corresponding die set. The feed length of the coil material 2 to the downstream side by the material mechanism is determined. Then, in the n-th press work shown in FIG. 11, when it is assumed that the coil material 2 moves downstream by the feed length determined by the feed length determination unit 77, each die set in FIG. As can be seen from the comparison of the Y movable range and the corresponding most downstream machining position, all the most downstream machining positions (the most downstream first to fifth machining positions) are within the movable range of the corresponding die set. Is located.

  Note that in the (n + 2) th press working shown in FIG. 15, assuming that the coil material 2 is moved downstream by the feed length determined by the feed length determining unit 77, the third machining position corresponds to the third machining position. This is outside the movable range of the three-die set 30. The third die set 30 that is outside the movable range is not a target for determination of interference or non-interference between adjacent die sets in step S6.

  Similarly, in the (n + 3) th press processing shown in FIG. 17, the second processing position and the third processing position are out of the movable range of the corresponding die set. In the (n + 4) th press processing shown in FIG. 21 is outside the movable range of the corresponding second die set, and in the (n + 5) th press processing shown in FIG. 21, the second processing position is outside the movable range of the corresponding second die set 20, and the (n + 6) th press processing shown in FIG. Then, the first machining position is out of the movable range of the corresponding first die set 10, and there is no machining position outside the movable range in the n + 7th press work shown in FIG.

  Next, in step S6, the selected fifth die set 50 is adjusted to the most downstream processing position corresponding to the selected fifth die set 50 by the motion control unit 71, and the other four die sets that are not selected correspond to the corresponding maximum die set 50. Assuming that the operation control unit 71 adjusts the position to the downstream processing position, the die set selection unit 75 stores other die sets in the die set storage unit 76 when adjacent die sets do not interfere with each other. When any of the die sets interfere with each other, the other die sets are not stored in the die set storage unit 76.

  In this case, the fourth die set 40 interferes with the fifth die set 50 and is not stored in the die set storage unit. Specifically, the dimension of the fourth die set 40 in the Y direction is 250 mm, and the dimension of the fifth die set 50 in the Y direction is 150 mm. Since the center of the fifth die 51 of the fifth die set 50 to be prioritized is arranged at the Y coordinate 1350, the fifth die set 50 occupies a position of 1350 ± 75 mm. On the other hand, when the center of the fourth die 41 of the fourth die set 40 is arranged at the Y coordinate 1290, the fourth die set 40 occupies a position of 1290 ± 125 mm and interferes with the fifth die set 50. .

  Since the first die set 10, the second die set 20, and the third die set 30 do not interfere with adjacent die sets, in step S7, the die set storage unit 76 stores the first die set in addition to the fifth die set 50. The set 10, the second die set 20, and the third die set 30 are also stored.

  If the first die set 10 and the second die set 20 interfere with each other, it can be determined based on the distance between the most downstream machining position and the lower limit. As described above, the distance between the most downstream first machining position (Y-axis value: 110) and the first lower limit (−250) is “360”, which is the most downstream second machining position (380). Since the distance from the second lower limit (100) is “280”, in this case, the second die set 20 is prioritized over the first die set 10, and the die set storage unit 76 replaces the first die set 10. The second die set 20 is stored without storing.

  In step S8, the operation control unit 71 moves the fourth die set 40 not stored in the die set storage unit 76 to the retracted position as shown in FIG. Since the subsequent steps are as described above, the description thereof is omitted.

  Similarly, FIGS. 12 and 13 show the n + 1 press process, FIGS. 14 and 15 show the n + 2 press process, FIGS. 16 and 17 show the n + 3 press process, FIGS. 18 and 19. Is the n + 4th press work, FIGS. 20 and 21 are the n + 5th press work, FIGS. 22 and 23 are the n + 6th press work, and FIGS. 24 and 25 are the n + 7th press work. It is a table which shows the coordinate data etc. of each die set in. Since these control flows are performed in the same manner as in the n-th time, the description thereof is omitted.

  As described above, in the present embodiment, the arrangement pattern is stored in the arrangement pattern storage unit 72, and the operation control unit 71 controls the first to fifth die sets and the feed mechanism, so that the arrangement pattern is stored. The coil material 2 is pressed.

  In the present embodiment, the first, second, fourth, and fifth die sets can be adjusted in the X direction within a predetermined movable range in the X direction, and Y within the predetermined movable range in the Y direction. The position of the direction can be adjusted, and the first mold can be rotated around its axis. The third die set can be adjusted in the X direction within a predetermined movable range in the X direction, and the second mold can be rotated about its axis. These die sets press the coil material 2 after the operation control unit 71 adjusts the processing position and the rotation angle of the mold. And in order to perform the next press work, an operation control part controls a feed mechanism, and adjusts the feed length which sends coil material 2 to the lower stream side to the 1st die set and the 2nd die set. In the same manner as described above, the machining position and the rotation angle θ of each die set are adjusted. Thereafter, the operation control unit 71 performs press working of the coil material 2. As described above, in this configuration, the processing position and the rotation angle θ of each die set can be adjusted for each press processing. It becomes easy to deal with complex arrangement patterns that prioritize improvement. Therefore, the yield can be improved effectively.

  Moreover, in the said embodiment, since a some processing position can be arranged in the arbitrary positions of the X direction of a coil material 2, and a Y direction, it is not necessary to divide the coil material 2 beforehand and a wide base material is directly pressed can do. Thereby, material cost can further be reduced.

  In the present embodiment, the die set selection unit 75 compares the distance between the most downstream machining position and the lower limit among a plurality of die sets, selects the die set with the smallest distance, and stores the die set. This is stored in the unit 76. In a system in which the coil material 2 is fed in one direction, the coil material 2 cannot be returned to the upstream side, but a die set having a machining position with the smallest distance from the lower limit as in this configuration is preferentially die set. By storing the data in the storage unit 76, the processing position can be reliably pressed. Thereby, it can prevent that the process position which passes a die set, without being press-processed arises.

  In the present embodiment, the die set selection unit 75 determines whether to store the remaining die sets in the die set storage unit 76 based on the presence or absence of interference between the die sets. By adopting such a configuration, press working can be performed using as many die sets as possible, so that the working efficiency can be improved.

  In the present embodiment, when there is a die set that is not used for press working, the single pressurizing unit 91 is pushed in the pressing direction with the die set moved to the retracted position, and the coil material 2 Is pressed. On the other hand, when all the die sets are used for press working, the single pressurizing unit 91 is pushed in the pressing direction, and the processing position corresponding to each die set is pressed. Therefore, it is not necessary to provide a pressurizing unit for each die set and control these pressurizing units individually, so that the structure and control of the system can be simplified.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment, A various change, improvement, etc. are possible in the range which does not deviate from the meaning.

  For example, in the above-described embodiment, the case where the third die set 30 cannot move in the Y direction is illustrated. However, the present invention is not limited to this. Good. However, as in the above-described embodiment, by omitting the Y-direction position adjusting mechanism in one of the plurality of die sets, there is an advantage that the structure of the position adjusting mechanism can be simplified and the cost can be reduced. In particular, since the third die set 30 is larger in size than the other die sets, the above-described merit is greater than when the Y-direction position adjusting mechanism is omitted in the other die sets.

  In the above-described embodiment, the example in which all the molds are simultaneously pushed in the pressing direction by the single pressurizing unit 91 is illustrated, but the present invention is not limited to this. For example, a mechanism for individually pressing each mold in the pressing direction may be employed.

  In the above embodiment, the case where five die sets are provided is illustrated, but two or more die sets may be provided.

  In the above embodiment, the case where the position of the third die set is adjustable only in the X direction is exemplified, but the position of the third die set may be adjustable in the Y direction as well as other die sets.
