In the following description, the three directions orthogonal to each other are defined as the x-axis direction (parallel to the paper surface in FIG. 12 and the left-right direction), the y-axis direction (direction perpendicular to the paper surface in FIG. 12 in a direction parallel to the paper surface and perpendicular to the x-axis).

  As shown in FIG. 12, the punching device 1 includes a feeding mechanism A, a winding mechanism B, a punching mechanism C, a feeding mechanism D, and a pair of tension mechanisms E1 and E2.

  The feeding mechanism A has a feeding roller 11 and guide rollers 13, 15, 17 and is assembled to the left side of the machine base 2. The feed roller 11 is rotationally driven in the clockwise direction in FIG. 12 to feed the roll-shaped workpiece W along the x-axis direction. Further, by the rewinding function, the feeding roller 11 is urged to rotate counterclockwise in FIG. 12 with a predetermined torque, so that the sheet-like workpiece W is rewound in a roll shape along the x-axis direction. It is configured.

JP 2001-341097 A (FIG. 1)

  By the way, in the above-mentioned punching apparatus 1, since it punches with respect to the sheet-like workpiece W conveyed in a horizontal direction toward the winding mechanism B side from the feeding mechanism A side, it is sheet-like. The workpiece W is bent in the vertical direction by its own weight. For this reason, in the above-described perforating apparatus 1, the tension is applied to the sheet-like workpiece W by the tension mechanisms E1 and E2 so as to suppress the bending.

  However, since it is necessary to apply a strong tension in order to suppress the vertical deflection by applying a horizontal tension, the sheet-like workpiece W is in a state where the tension is applied. On the other hand, when the tension is released, the extended state is released. For this reason, the sheet-like workpiece W is stretched before and after the drilling, and the drilling accuracy is deteriorated. As a result, the above-described punching apparatus 1 has a problem that it is not easy to perform highly accurate drilling on such a sheet-like workpiece W.

  Accordingly, the present invention has been made to solve such a problem, and an object thereof is to provide a drilling apparatus capable of performing drilling with high accuracy.

A conveyance mechanism that conveys a sheet-like workpiece along the vertical direction from the feeding mechanism side toward the winding mechanism side, and a punch mold and a die for punching the sheet-like workpiece And a drilling mechanism having a working mold.

  For this reason, according to the punching apparatus of the present invention, since punching is performed on the sheet-like workpiece conveyed along the vertical direction, the sheet-like workpiece near the punching position is formed. No deflection occurs due to its own weight.

  As a result, it is not necessary to apply a strong tension to the sheet-like workpiece, so that deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is suppressed, and the sheet-like workpiece is accurate. High drilling can be performed.

  In the punching apparatus of the present invention, in order to perform highly accurate drilling on a sheet-like workpiece, the sheet-like workpiece may be transported along the vertical direction. The sheet-like workpiece can be transported along the direction of gravity from the feeding mechanism side to the winding mechanism side, or in the direction of gravity from the feeding mechanism side to the winding mechanism side. It can also be configured to be conveyed on the contrary.

  Here, in this specification, the term “convey along the vertical direction (gravity direction)” is used in a broader sense than the meaning of the vertical direction (gravity direction). That is, it includes a substantially vertical direction (substantially gravitational direction).

(2) In the punching device according to (1), it is preferable that the punching device further includes a moving block that supports the punching mechanism and is movable in the vertical direction and the horizontal direction.

  By comprising in this way, a punching process can be easily implemented in a desired position with respect to a sheet-like workpiece.

(3) In the perforating apparatus according to (2), the moving block includes a base portion for supporting either one of the punch die and the die die, and both end portions of the base portion. And a ceiling portion that is coupled to the base portion and supports the other of the punch die and the die die.

  By configuring in this way, the rigidity of the moving block can be increased, so that the positional accuracy of the punch die relative to the die die can be increased, and the occurrence of return of the section due to perforation can be prevented. it can. Moreover, the speed of perforation can be increased.

  Here, in the moving block of the present invention, the ceiling portion is coupled to the base portion at both ends of the base portion, but the base portion and the ceiling portion may be directly or indirectly connected, or the base portion and the ceiling portion may be connected. It may be united.

(4) In the punching device according to (3), it is preferable that the die mold is supported on a base portion of the moving block and the punch mold is supported on a ceiling portion of the moving block.

  By configuring in this way, a punch mold having a relatively complicated structure and a large volume is supported by a ceiling portion having a relatively large space. Further, a die mold having a relatively simple structure and a small volume is supported by a base portion having a relatively small space. This facilitates the design when the punching die or die die is supported by the moving block.

(5) In the punching device according to (3), it is preferable that the punching die is supported by a base portion of the moving block, and the die die is supported by a ceiling portion of the moving block.

  By configuring in this way, a punching die having a relatively complicated structure and a large weight is supported by the base portion, and a die die having a relatively simple structure and a light weight is supported by the ceiling portion. . For this reason, the weight balance of the moving block is improved, and the moving block can be reduced in weight. As a result, the movement of the drilling mechanism is increased, and the drilling process can be performed at higher speed.

  In addition, since the punch mold including the drive mechanism for driving the punch is supported by the base, the vibration level of the moving block generated along with the drilling can be made extremely small. For this reason, it becomes possible to carry out drilling with higher accuracy on the sheet-like workpiece.

  In addition, since a mechanism for processing punch waste produced when drilling is performed can be provided in a ceiling portion having a relatively large space, punch scrap processing is facilitated.

  With this configuration, the punching process is performed on the sheet-like workpiece gripped by the first clamper and the second clamper, and thus the sheet-like workpiece is perpendicular to the conveying direction. Generation of bending along a certain direction (that is, the horizontal direction) is effectively suppressed. For this reason, the tension | tensile_strength which needs to be provided to a sheet-like workpiece can be made still weaker. As a result, the deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is further suppressed, and the punching processing with higher accuracy can be performed on the sheet-like workpiece.

  In the punching device described in (6) above, a clamper that clamps the sheet-like workpiece from both ends may be provided as the first clamper. It is preferable to provide a first clamper that can be gripped in the width direction. Further, as the second clamper, a clamper that clamps the sheet-like workpiece from both ends may be provided. However, the second clamper can hold the sheet-like workpiece in the width direction of the sheet-like workpiece. It is preferable to provide a clamper.

  By comprising in this way, generation | occurrence | production of the bending along the direction (namely, horizontal direction) perpendicular | vertical to the conveyance direction of a sheet-like workpiece is further suppressed effectively. For this reason, since it is possible to further weaken the tension that needs to be applied to the sheet-like workpiece, the deterioration of the drilling accuracy due to the expansion and contraction of the sheet-like workpiece is further suppressed, and the sheet-like workpiece It becomes possible to carry out drilling with higher accuracy on the workpiece.

(7) In the perforating apparatus according to (6), the raising / lowering roller is controlled to be lifted / lowered by the tension and weight of the sheet-like workpiece, and the lifting / lowering is controlled by the tension and weight of the sheet-like workpiece.

  With this configuration, the lift roller on the feeding side and the lift roller on the take-up side are controlled to be lifted and lowered by the tension and the own weight of the sheet-like workpiece, respectively, so that the sheet-like workpiece is relatively weak. Tension can be easily applied. As a result, the deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is easily suppressed, and it becomes possible to easily carry out high-precision drilling on the sheet-like workpiece. .

  In this case, when moving the sheet-like workpiece to the winding mechanism side by the third clamper, it is preferable to stop the feeding mechanism and the winding mechanism. Further, when the third clamper moves the sheet-like workpiece to the winding mechanism side, the winding roller is lowered or raised correspondingly.

(8) In the punching apparatus according to (6), the feeding mechanism is configured to lift and lower the feeding side lift roller controlled by the tension and weight of the sheet-like workpiece, and to feed the sheet-like workpiece. A third clamper for moving from the side to the take-up mechanism side, with the third clamper releasing the gripping force on the sheet-like workpiece by the first clamper and the second clamper. The sheet-like workpiece is moved to the take-up mechanism side, and then the sheet-like workpiece is gripped by the first clamper and the second clamper and the sheet-like workpiece by the third clamper is It is also preferable to carry out perforation with the gripping force released.

With this configuration, the lifting roller on the feeding side is controlled to be lifted and lowered by the tension and weight of the sheet-like workpiece, so that it is easy to apply a relatively weak tension to the sheet-like workpiece. become able to. As a result, the deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is easily suppressed, and it becomes possible to easily carry out high-precision drilling on the sheet-like workpiece. .
In this case, since the tension by the lifting roller on the winding side is not applied, the tension applied to the sheet-like workpiece can be further weakened. For this reason, the deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is further suppressed, and the punching processing with higher accuracy can be performed on the sheet-like workpiece.

  In this case, it is preferable to stop the feeding mechanism when the third clamper moves the sheet-like workpiece to the winding mechanism side. Further, when the third clamper moves the sheet-like workpiece to the take-up mechanism side, the take-up mechanism is appropriately driven accordingly.

(9) In the punching device according to any one of (1) to (8), the punching device is a warp correction mechanism for correcting the warp of the sheet-like workpiece, and is conveyed along the vertical direction. The apparatus further includes a warp correction mechanism having a pair of element members that are arranged so as to face each other via the sheet-like workpiece and are provided with through holes for blowing air toward the sheet-like workpiece. It is preferable.

  With this configuration, the warpage of the workpiece is corrected by the warp correction mechanism, so that it is possible to perform drilling with higher accuracy. Further, at that time, by blowing air from each element member toward the sheet-like workpiece, contact of the workpiece against each element member is avoided when guiding the sheet-like workpiece, The occurrence of damage to the sheet-like workpiece by each element member can be prevented.

  In this case, the warp correction mechanism is preferably arranged in the vicinity of the punching position. This is because the warpage of the sheet-like workpiece is corrected in the vicinity of the drilling position, and drilling with higher accuracy can be performed. From this point of view, it is more preferable that the warp correction mechanism is disposed on the moving block.

  In addition to air, nitrogen and other gases can be used as air.

(13) In the punching device according to (6), the first clamper is rotated, and the first clamper is moved in the vicinity of the feeding mechanism (hereinafter referred to as “the conveyance path of the sheet-like workpiece”). "It is referred to as a" conveying path on the feeding mechanism side ") and a conveying path for a sheet-like workpiece positioned on the punching position side (hereinafter referred to as" a conveying path on the punching position side "). It is preferable to further include a first clamper rotating mechanism.

  With this configuration, the feeding mechanism is brought to a relatively high position by causing the first clamper to grip the sheet-like workpiece and rotating the first clamper in that state by the first clamper rotating mechanism. In some cases, the sheet-like workpiece can be smoothly routed from the conveyance path on the feeding mechanism side to the conveyance path on the punching position side.

And a guide for projecting air toward the sheet-like workpiece by projecting toward the region where the first clamper rotates by driving the first clamper rotating mechanism. It is preferable to have a curved surface provided with through holes.

  With this configuration, air is blown out from the guide through-hole for guiding the sheet-like workpiece, thereby avoiding contact of the sheet-like workpiece with the guide. For this reason, it is possible to prevent the sheet-like workpiece from being damaged when the sheet-like workpiece is guided.

(15) In the punching device according to any one of (1) to (14), the feeding mechanism includes a feeding roller for feeding a roll-shaped workpiece, and the feeding roller is a roller shaft thereof. It is preferable to further include a feeding roller rotating mechanism that rotates in a plane parallel to the.

  With this configuration, the roll-like workpiece is mounted on the feeding roller while the feeding roller is rotated to the workpiece mounting position, and then the feeding roller is rotated by the feeding roller rotating mechanism. By rotating to the feeding position, the roll-shaped workpiece can be smoothly mounted on the feeding roller.

(16) In the punching device according to any one of (1) to (15), the winding mechanism includes a winding roller for winding a sheet-like workpiece, and the winding roller It is preferable to further include a take-up roller rotating mechanism that rotates the roller in a plane parallel to the roller shaft.

  With this configuration, the take-up roller in which the sheet-like work is wound in a roll shape at the work take-up position is moved to the work collection position by the take-up roller rotating mechanism. By rotating and then collecting the roll-like workpiece from the take-up roller, the roll-like workpiece from the take-up roller can be collected smoothly.

(17) In the perforating apparatus according to any one of (1) to (16), an alignment roller for controlling the position of the sheet-like workpiece in the width direction of the sheet-like workpiece is fixed. It is preferable to further provide.

  By comprising in this way, the position of the sheet-like workpiece in the width direction of a sheet-like workpiece can be controlled uniformly. For this reason, it becomes possible to carry out drilling with higher accuracy on a sheet-like workpiece by simply adding an alignment roller having a simple mechanism.

  (18) In the punching device according to any one of (1) to (16), the position of the sheet-like workpiece in the width direction of the sheet-like workpiece is measured, and based on the measurement result. It is also preferable to further include a control mechanism for dynamically controlling the position of the sheet-like workpiece in the width direction of the sheet-like workpiece.

  By comprising in this way, the position of the sheet-like workpiece in the width direction of a sheet-like workpiece can be controlled very precisely. For this reason, it becomes possible to carry out drilling with higher accuracy on the sheet-like workpiece.

(19) In the punching device according to any one of (1) to (18), the feeding mechanism and the winding mechanism are installed on the front side of the punching mechanism, and the feeding mechanism and the winding mechanism It is preferable that at least one of the taking mechanisms is movable up and down along the vertical direction.

  With this configuration, since the feeding mechanism and the winding mechanism are installed on the front side of the punching mechanism, the roll-shaped workpiece is mounted from the winding roller or the work for mounting the roll-shaped workpiece onto the feeding roller. The work of collecting the workpiece can be easily performed. Further, when it is necessary to replace the punching die or die die, it is possible to move up and down along the vertical direction by moving at least one of the feeding mechanism and the winding mechanism. Replacement work can be easily performed.

(20) The punching device of the present invention has a feeding mechanism for feeding a roll-like workpiece into a sheet shape and a winding mechanism for winding the sheet-like workpiece into a roll shape. A conveying mechanism that conveys a sheet-like workpiece along the horizontal direction from the feeding mechanism side toward the winding mechanism side, two moving blocks that are movable in the horizontal direction orthogonal to each other, and the moving block A punching device comprising a punching die for punching a supported workpiece and punching a sheet-like workpiece and a punching mechanism having a die die, and disposed on the feeding mechanism side of the punching mechanism, A first clamper capable of gripping the sheet-like workpiece in the width direction of the sheet-like workpiece and the winding mechanism side of the punching mechanism are arranged, and the sheet-like workpiece is arranged in a sheet-like manner. A second clamper that can be gripped in the width direction of the workpiece, and a warp correction mechanism for correcting warpage of the sheet-like workpiece, the sheet-like workpiece being conveyed along the horizontal direction And a warp correction mechanism having a pair of element members which are arranged so as to face each other via a sheet and are provided with through holes for blowing air toward a sheet-like workpiece. To do.

  Therefore, according to the punching device of the present invention, the deflection of the sheet-like workpiece is corrected by the first clamper and the second clamper, and further, the warpage of the workpiece is corrected by the warp correction mechanism. For this reason, a highly accurate drilling process can be implemented. At that time, air is blown out from each element member toward the sheet-like workpiece, so that when the sheet-like workpiece is guided, the contact of the sheet-like workpiece to each element member is prevented. It is avoided, and the occurrence of damage to the sheet-like workpiece by each element member can be prevented.

  In this case, the warp correction mechanism is preferably arranged in the vicinity of the punching position. This is because the warpage of the sheet-like workpiece is corrected in the vicinity of the drilling position, and drilling with higher accuracy can be performed. From this point of view, it is more preferable that the warp correction mechanism is disposed on the moving block.

In the punching device according to (20), the moving block includes a plurality of moving blocks that can move independently of each other, and the punching mechanism includes a plurality of punching mechanisms that can punch independently of each other, Each moving block preferably supports each drilling mechanism.
With this configuration, each moving block moves in the vertical direction and the horizontal direction in different regions, and the punching mechanism of each moving block punches the sheet-like workpiece. For this reason, drilling can be performed at a higher speed.

In the punching device according to the above (20), the punch die has a plurality of punches configured to be movable up and down in a hoistway, and one punch for punching out of the plurality of punches is provided. It is preferable that a selection mechanism for selecting and punching is provided, and the die mold has a plurality of die holes arranged corresponding to the plurality of punches of the punch mold.
With this configuration, even if one punch is worn or damaged, the punch that replaces the worn one punch with a new punch by operating the punch die selection mechanism. The replacement work can be performed without removing the punching die from the punching device. For this reason, the trouble of removing and attaching the punching die at the time of punch replacement can be saved, so that the work time required for punch replacement can be shortened and the operating rate of the punching apparatus can be increased.

(21) In the punching device according to (1) to (20), the punching mechanism has a gap between the punch mold and the die mold larger than the thickness of the sheet-like workpiece. A drilling mechanism that performs drilling in a state is preferable.

With this configuration, since punching is performed on the sheet-like workpiece conveyed along the vertical direction, the sheet-like workpiece near the punching position is bent by its own weight. Will not occur. For this reason, a punching operation is performed at a correct angle with respect to the workpiece, and the punch can be smoothly removed from the workpiece. As a result, since it becomes possible to perform drilling in a state where the gap between the punch mold and the die mold is larger than the thickness of the sheet-like workpiece, a stripper can be dispensed with. It becomes like this. Therefore, according to the punching device of the present invention, the number of parts can be reduced, the cost can be reduced, and the mold structure can be simplified.
Further, since the drilling is performed in a state where the workpiece is in a non-pressed state, occurrence of damage to the workpiece can be suppressed, and reliability in quality can be improved.
In addition, since the punching is performed in a state where the gap between the punching die and the die die is larger than the thickness of the sheet-like workpiece, the punching die itself does not need to be moved up and down at the time of punching. Since only the punch needs to be raised and lowered, it is easy to speed up the drilling.

(22) In the punching device according to (21), the punching mechanism performs the punching in a state where the gap between the punching die and the die die is 0.10 mm to 5.0 mm. It is preferable.
Here, the reason why the gap is set to 0.10 mm or more is that if the gap is less than 0.10 mm, a relatively thick workpiece may not be drilled. From this point of view, the gap is more preferably 0.20 mm or more, and further preferably 0.30 mm or more. The reason why the gap is set to 5.0 mm or less is that if the gap exceeds 5.0 mm, it is not easy to ensure the positional accuracy between the tip of the punch and the die hole. This is because it is not easy to maintain straightness. From this point of view, the gap is more preferably 3.0 mm or less, and further preferably 2.0 mm or less.

(23) In the punching device according to (20) or (21), the punching mechanism performs punching without a guide pin interposed between the punching die and the die die. It is preferable.
By constructing in this way, it becomes possible to place a large-area workpiece between the punch mold and the die mold, so that a large-area workpiece is drilled. Will be able to.

(24) The punching method of the present invention is characterized in that punching is performed on a sheet-like workpiece conveyed in a vertical direction at a punching position.

For this reason, according to the punching method of the present invention, since the punching is performed on the sheet-like workpiece conveyed in the vertical direction, the workpiece near the punching position is bent by its own weight. It will not occur.
As a result, it is not necessary to apply a strong tension to the sheet-like workpiece, so that deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece is suppressed, and the sheet-like workpiece is accurate. High drilling can be performed.

(25) The product of the present invention is a product manufactured using a workpiece drilled by the drilling device according to any one of (1) to (23).

  For this reason, the product of the present invention is manufactured using a high-quality workpiece that has been drilled with high accuracy by the drilling device according to any one of the above (1) to (23).

Here, since the 1st correction mechanism 910 and the 2nd correction mechanism 920 are comprised substantially the same, only the one 1st correction mechanism 910 is demonstrated. As shown in FIG. 6, the first correction mechanism 910 includes a pair of element members 912 and 914 that are arranged to face each other via a sheet-like workpiece W that is conveyed along the z-axis direction. is doing. As shown in FIG. 6B, the element members 912 and 914 have a plurality of through holes 930 and 932 for blowing air toward the sheet-like workpiece W, and passages communicating with the through holes 930 and 932. 940, 942 are provided.

For example, air is used as the air.

  Since the perforation apparatus 100 according to the first embodiment includes the warp correction mechanism 900 described above, the warp correction mechanism 900 corrects the warp of the sheet-like workpiece W. For this reason, it becomes possible to carry out drilling with higher accuracy. At that time, air is blown out from each element member toward the sheet-like workpiece W, so that when the sheet-like workpiece W is guided, the workpiece W comes into contact with each element member. It is avoided and the occurrence of damage to the sheet-like workpiece W by each element member can be prevented.

  In the punching device 100 according to the first embodiment, the warp correction mechanism 900 is disposed on the moving block as described above. Thereby, the warp of the sheet-like workpiece W is corrected in the vicinity of the drilling position, and drilling with higher accuracy can be performed.

  In order to perform drilling on the workpiece W using the drilling apparatus 100 configured as described above, the process is performed as follows. The first clamper 810 grips the workpiece W that has been fed from the feeding roller 310 in advance, and moves in this state from the feeding path a on the feeding mechanism side to the feeding path c on the punching position side. To do. In addition, it is assumed that a reference mark (display mark for reading the drilling position) is displayed on the workpiece W.

  First, as shown in FIG. 2, the gripping force for the sheet-like workpiece W by the first clamper 810 is released, and the sheet-like workpiece W is interposed between the punch die 720 and the die die 730. Is further wound up by the winding roller 410 so that the workpiece W can be supplied to the drilling position. In this case, when the workpiece W can be supplied, weights of the lifting rollers 510 and 560 of the tension mechanisms 500 and 550 are applied to both ends of the workpiece W, respectively.

Next, the feeding mechanism 300, the winding mechanism 400, and the moving mechanism 600 (first moving mechanism 610) are driven in synchronization, and the workpiece W is quantitatively supplied from the feeding side to the winding side. Specifically, the sheet feeding mechanism 300 and the winding mechanism 400 are stopped, and the third clamper 660 releases the sheet with respect to the sheet-like workpiece W by the first clamper 810 and the second clamper 820. The workpiece W is moved.
When the third workpiece 660 moves the sheet-like workpiece W to the winding mechanism 400 side, the winding-side lifting roller 560 is lowered or raised correspondingly.

  Thereafter, the first clamper 810 and the second clamper 820 hold the sheet-like workpiece W, and the punching is performed in a state where the gripping force on the sheet-like workpiece W by the third clamper 660 is released.

  In this way, the feeding-side lifting roller 510 and the winding-side lifting roller 560 are controlled to be lifted and lowered by the tension and weight of the sheet-like workpiece W, respectively, and as a result, compared with the sheet-like workpiece W. It is possible to easily apply a weak tension. As a result, the deterioration of the drilling accuracy due to the expansion and contraction of the sheet-like workpiece W can be easily suppressed, and a highly accurate drilling process can be easily performed on the sheet-like workpiece W. become.

  As described above, the punching device 100 according to the first embodiment includes a feeding mechanism 300 for feeding the roll-shaped workpiece W into a sheet shape, and a winding for winding the sheet-shaped workpiece W into a roll shape. A take-off mechanism 400, a pair of tension mechanisms 500, 550 for tensioning / relaxing the workpiece W between the feeding mechanism 300 and the take-up mechanism 400, and a movement interposed between the pair of tension mechanisms 500, 550. A mechanism 600, a punching mechanism 700 having a punching die 720 and a die mold 730 for punching a sheet-like workpiece W, and a workpiece W in a punched state by the punching mechanism 700. And a clamp mechanism 800. And it is comprised so that the sheet-like workpiece W may be conveyed along a perpendicular direction toward the winding mechanism 400 side from the feeding mechanism 300 side in the punching position.

  For this reason, according to the punching apparatus 100 according to the first embodiment, since the punching is performed on the sheet-like workpiece W conveyed along the vertical direction, the sheet-shaped workpiece near the punching position is formed. The workpiece W is not bent due to its own weight.

  As a result, since it is not necessary to apply a strong tension to the sheet-like workpiece W, deterioration of punching accuracy due to the expansion and contraction of the sheet-like workpiece W is suppressed, and the sheet-like workpiece W is reduced. On the other hand, it becomes possible to carry out drilling with high accuracy.

  The punching apparatus 100 according to the first embodiment includes a moving block that supports the punching mechanism 700 and is movable in the vertical direction and the horizontal direction. Thereby, it becomes possible to easily perform drilling at a desired position on the sheet-like workpiece W.

  In the perforating apparatus 100 according to the first embodiment, the die mold 730 is supported on the base of the moving block, and the punching mold 720 is supported on the ceiling of the moving block. As a result, the punch mold having a relatively complicated structure and a large volume is supported by the ceiling portion having a relatively large space. Further, a die mold having a relatively simple structure and a small volume is supported by a base portion having a relatively small space. This facilitates the design when the punching die or die die is supported by the moving block.

  In the punching device 100 according to the first embodiment, the first punch is disposed on the feeding mechanism 300 side of the punching mechanism 700 and can grip the sheet-like workpiece W across the width direction of the sheet-like workpiece W. A clamper 810 and a second clamper 820 that is disposed on the winding mechanism 400 side of the punching mechanism 700 and can grip the sheet-like workpiece W across the width direction of the sheet-like workpiece W are provided. As a result, the punching process is performed on the sheet-like workpiece W held by the first clamper 810 and the second clamper 820, and thus the sheet-like workpiece W is perpendicular to the conveying direction. The occurrence of bending along the direction (that is, the horizontal direction) is effectively suppressed. For this reason, the tension | tensile_strength which needs to be provided to the sheet-like workpiece W can be made still weaker. As a result, the deterioration of the punching accuracy due to the expansion and contraction of the sheet-like workpiece W is further suppressed, and the punching processing with higher accuracy can be performed on the sheet-like workpiece W. .

  In the drilling device 100 according to the first embodiment, the moving block includes a plurality of moving blocks that can move independently from each other, and the drilling mechanism includes a plurality of drilling mechanisms that can drill independently from each other. Respectively support each drilling mechanism. As a result, the respective moving blocks move in the vertical direction and the horizontal direction in different areas, and the punching mechanism of each of these moving blocks punches the sheet-like workpiece W. For this reason, drilling can be performed at a higher speed.

  In the punching device 100 according to the first embodiment, the punch die 720 includes a plurality of punches configured to be movable up and down in the hoistway, and selects one punch to be used for punching from the plurality of punches. The die mold 730 has a plurality of die holes arranged corresponding to the plurality of punches of the punch mold 720. Thereby, even when one punch is worn or damaged, by operating the selection mechanism of the punch mold 720, the punch replacement work for replacing the worn one punch with a new punch, The punching die can be performed without removing it from the punching device. For this reason, the trouble of removing and attaching the punching die at the time of punch replacement can be saved, so that the work time required for punch replacement can be shortened and the operating rate of the punching apparatus can be increased.

  The perforating apparatus 100 according to the first embodiment further includes an alignment roller for controlling the position of the sheet-like workpiece W in the width direction of the sheet-like workpiece W to be constant. FIG. 8 is a view for explaining the alignment roller of the punching device according to the first embodiment.

  The alignment roller 260 has a structure in which flanges 264 are provided on both sides of the roller body 262, as shown in FIG. For this reason, in the punching device 100 according to the first embodiment, the position of the sheet-like workpiece W in the width direction of the sheet-like workpiece W is corrected by the flange 264, and thus the sheet-like workpiece W is corrected. The position of the sheet-like workpiece W in the width direction can be controlled to be constant. For this reason, according to the punching apparatus 100 according to the first embodiment, it is possible to perform the drilling with higher accuracy on the sheet-like workpiece W.

  The alignment roller is preferably arranged between the feeding mechanism and the punching mechanism. Thereby, the position of the sheet-like workpiece W in the width direction of the sheet-like workpiece W can be well controlled.

  In the punching device 100 according to the first embodiment, the punching mechanism 700 performs the punching in a state where the gap between the punching die 720 and the die die 730 is larger than the thickness of the sheet-like workpiece W. It is a perforating mechanism.

Thereby, since the punching is performed on the sheet-like workpiece W conveyed along the vertical direction, the sheet-like workpiece W near the punching position is bent by its own weight. Nothing will happen. For this reason, a punching operation is performed at a correct angle with respect to the workpiece, and the punch can be smoothly removed from the workpiece. As a result, it becomes possible to carry out drilling in a state in which the gap between the punch mold 720 and the die mold 730 is larger than the thickness of the sheet-like workpiece W, so that a stripper is not required. Will be able to. Therefore, according to the punching device 100 according to the first embodiment, the number of parts can be reduced, the cost can be reduced, and the mold structure can be simplified.
Further, since the drilling is performed in a state where the workpiece W is in a non-pressed state, occurrence of damage to the workpiece W can be suppressed, and reliability in quality can be improved.
Further, since the punching is performed in a state where the gap between the punching die 720 and the die die 730 is larger than the thickness of the sheet-like workpiece, the punching die itself needs to be raised and lowered during the punching. Therefore, it is sufficient to raise and lower only the punch, so that it is easy to speed up the drilling.

  In the punching apparatus 100 according to the first embodiment, the punching mechanism 700 performs the punching in a state where the gap between the punching die 720 and the die die 730 is 0.10 mm to 5.0 mm. It is configured.

  In the punching device 100 according to the first embodiment, the punching mechanism 700 is configured to perform punching without a guide pin interposed between the punching die 720 and the die die 730. As a result, a large-area workpiece can be placed between the punch mold 720 and the die mold 730, so that a large-area workpiece can be drilled. become.

  The punching method according to the first embodiment is a punching method for punching a sheet-like workpiece W that is conveyed in the vertical direction at the punching position.

  For this reason, according to the punching method according to the first embodiment, since the punching is performed on the sheet-like workpiece W conveyed in the vertical direction, the weight of the workpiece near the punching position is reduced. No bending occurs. As a result, since it is not necessary to apply a strong tension to the sheet-like workpiece W, deterioration of punching accuracy due to the expansion and contraction of the sheet-like workpiece W is suppressed, and the sheet-like workpiece W is reduced. On the other hand, it becomes possible to carry out drilling with high accuracy.

  For this reason, according to the punching device 1100 according to the second embodiment, the feeding mechanism 1300 and the winding mechanism 1400 are installed on the front side of the punching mechanism 1700 (see FIG. 11A). The operation of mounting the roll-shaped workpiece W and the operation of collecting the roll-shaped workpiece W from the take-up roller 1410 can be easily performed.

  Further, as shown in FIGS. 10A and 10B, the feeding mechanism 1300 can move up and down along the vertical direction. As a result, when the punch mold 1720 or the die mold 1730 (see FIG. 11A) needs to be replaced, the feed mechanism 1300 is moved vertically as shown in FIG. Such an exchange operation can be easily performed by moving it up along the direction. Further, in the case of performing an operation of mounting the roll-shaped workpiece W on the feeding roller 1310, as shown in FIG. 10B, by moving the feeding mechanism 1300 downward along the vertical direction, Such a mounting operation can be easily performed.

  In the punching device 1100 according to the second embodiment, the configuration in which the feeding mechanism 1300 can move up and down along the vertical direction is illustrated, but the winding mechanism 1400 can move up and down along the vertical direction. Alternatively, the feeding mechanism 1300 and the winding mechanism 1400 may be movable up and down along the vertical direction.

  As shown in FIG. 11, the punching apparatus 1100 according to the second embodiment is different from the punching apparatus 100 according to the first embodiment in the positions where the punch mold and the die mold are disposed. In addition, the structure of the moving block is different with the positions where the punch mold and the die mold are disposed. That is, in the punching apparatus 100 according to the first embodiment, as shown in FIG. 5, the die mold 730 is supported by the base (table 623) of the moving block 631, and the punching mold 720 is the moving block 631. It is supported by the ceiling portion 635. On the other hand, in the punching device 1100 according to the second embodiment, as shown in FIG. 11A, the punch die 1720 is supported by the base 1623 of the moving block 1631, and the die die 1730 is moved by the moving block 1631. The ceiling part 1635 is supported.

  For this reason, according to the punching apparatus 1100 according to the second embodiment, the punch mold 1720 having a relatively complicated structure and a large weight is supported by the base portion 1623, and the die mold 1730 having a relatively simple structure and a light weight. Is supported by the ceiling 1635. As a result, the weight balance of the moving block is improved and the moving block can be reduced in weight, so that the movement of the drilling mechanism is increased and the drilling process can be performed at higher speed.

  In addition, since the punch die 1720 including a drive mechanism for driving the punch is supported by the base 1623, the vibration level of the moving block 1631 generated along with the drilling can be made extremely small. it can. For this reason, it becomes possible to carry out drilling with higher accuracy for the sheet-like workpiece W.

  In addition, since a mechanism for processing punch scraps produced when drilling is performed can be provided in the ceiling 1635 having a relatively large space, punch scrap processing is facilitated.

  As described above, the punching device 1100 according to the second embodiment is configured so that the positions where the feeding mechanism and the winding mechanism are installed and the positions where the punching die and the die die are disposed are according to the first embodiment. Although different from the case of the apparatus 100, as in the case of the punching apparatus 100 according to the first embodiment, the sheet-like workpiece W is vertically moved from the feeding mechanism 1300 side to the winding mechanism 1400 side at the punching position. It is comprised so that it may convey along a direction.

  For this reason, according to the punching apparatus 1100 according to the second embodiment, since the punching is performed on the sheet-like workpiece W conveyed along the vertical direction, the sheet-shaped workpiece near the punching position is formed. The workpiece W is not bent due to its own weight.

  As a result, since it is not necessary to apply a strong tension to the sheet-like workpiece W, deterioration of punching accuracy due to the expansion and contraction of the sheet-like workpiece W is suppressed, and the sheet-like workpiece W is reduced. On the other hand, it becomes possible to carry out drilling with high accuracy.

  In the punching device 1100 according to the second embodiment, the lifting roller 1510 that is lifted and lowered by the tension and the own weight of the sheet-like workpiece W, and the sheet-like workpiece W are gripped and wound from the feeding mechanism 1300 side. A third clamper 1660 for moving toward the mechanism 1400 side, and the third clamper 1660 releases the gripping force on the workpiece W by the first clamper 1810 and the second clamper 1820. The workpiece W is moved to the take-up mechanism 1400 side, and then the sheet-like workpiece W is gripped by the first clamper 1810 and the second clamper 1820 and the sheet-like workpiece by the third clamper 1660 is moved. Drilling is performed with the gripping force against W released.

For this reason, according to the punching device 1100 according to the second embodiment, the lifting roller 1510 of the tension mechanism 1500 is controlled to be lifted and lowered by the tension and the own weight of the sheet-like workpiece W. A relatively weak tension can be easily applied. As a result, the deterioration of the drilling accuracy due to the expansion and contraction of the sheet-like workpiece W can be easily suppressed, and a highly accurate drilling process can be easily performed on the sheet-like workpiece W. become.
In this case, unlike the case of the punching device 100 according to the first embodiment, no tension is applied by the lifting roller on the winding side, so that the tension applied to the sheet-like workpiece W can be further reduced. . For this reason, the deterioration of the drilling accuracy due to the expansion and contraction of the sheet-like workpiece W is further suppressed, and it becomes possible to perform the drilling processing with higher accuracy on the sheet-like workpiece.

  In the punching device 1100 according to the second embodiment, when the sheet-like workpiece W is moved to the winding mechanism 1400 side by the third clamper 1660, the feeding mechanism 1300 is stopped. When the third clamper 1660 moves the sheet-like workpiece W to the winding mechanism 1400 side, the winding mechanism 1400 is appropriately driven correspondingly.

  In the punching device 1100 according to the second embodiment, the position of the sheet-like workpiece W in the width direction of the sheet-like workpiece W is measured, and the sheet-like workpiece W is measured based on the measurement result. A control mechanism (not shown) for dynamically controlling the position of the sheet-like workpiece W in the width direction is further provided. Thereby, the position of the sheet-like workpiece W in the width direction of the sheet-like workpiece W can be controlled extremely precisely. For this reason, it becomes possible to carry out drilling with higher accuracy on the sheet-like workpiece W.
