Disclosure of the invention

Problems to be solved by the invention [0007] However, in the conventional punching apparatus, in order to punch a strip-shaped workpiece, drilling is performed with both ends of the strip-shaped workpiece clamped by a clamper. Because it is necessary, it is impossible to drill on both ends of the strip-shaped workpiece because the clamper gets in the way, and drilling cannot be performed on the entire surface of the strip-shaped workpiece. There was a problem!

[0008] In such a case, the first drilling operation is performed in a state where only one end of the strip-shaped workpiece is clamped by the clamper, and then only one end on the side where the drilling is performed is clamped. If the second drilling operation is carried out in the reworked state, it is possible to perform the drilling in the second drilling operation even at one end of the side where the drilling has not been performed in the first drilling operation. Therefore, it will be possible to perforate the entire surface of the strip-shaped article.

[0009] However, in this case, it is necessary to perform the drilling operation in two steps, and it is necessary to perform the operation of clamping the strip-shaped workpiece with the clamper twice. As a whole, there was a problem that the drilling work became complicated and it was not easy to improve the productivity of the drilling work.

Accordingly, the present invention has been made to solve such a problem, and provides a drilling apparatus capable of performing a drilling operation over the entire surface of a strip-shaped workpiece with high productivity. The purpose is to provide.

Means for solving the problem

[0011] (1) A punching device of the present invention is installed on a base and the base, and each has an upper roller and a lower roller, and feeds a strip-shaped force object as a work. 2 sets of workpiece feeding devices for horizontal movement while controlling positioning along the direction (hereinafter referred to as one direction), and a drilling mechanism for drilling a strip-shaped workpiece A punching device, wherein the punching mechanism includes a die die and a punch die, and has a punching die installed between the two sets of cake feeding devices, and the punching device The mechanism is configured to be horizontally movable along the other direction orthogonal to the one direction with respect to the base and to be finely movable along the one direction with respect to the base. Features.

[0012] Therefore, according to the punching device of the present invention, two sets of strip-shaped to-be-loaded objects as workpieces are provided. In addition to feeding by a workpiece feeder (advancing or retreating in one direction), a strip-shaped workpiece can also be fed by one of the two workpiece feeders. It becomes possible. As a result, the front end and the rear end of the strip-shaped workpiece can be sent to the drilling position in a free state. It is possible to perform perforation well at any end of the end.

[0013] Further, since the front end portion and the rear end portion of the strip-shaped workpiece can be sent to the drilling position by a series of operations of the two sets of workpiece feeding devices, the drilling operation is divided into two times. There is no need to do it.

Furthermore, since the strip-shaped workpiece can be grasped by the upper roller and the lower roller, the operation of clamping the strip-shaped workpiece with the clamper becomes unnecessary.

[0014] Therefore, the punching device of the present invention is a punching device that can perform the punching operation over the entire surface of the strip-shaped workpiece with high productivity, and the object of the present invention is achieved. The

[0015] In the punching device of the present invention, the position adjustment of the drilling position in one direction in the strip-shaped workpiece is performed using two sets of work feeding devices having an upper roller and a lower roller. This makes it possible to sufficiently adjust the position of the strip-shaped workpiece with high accuracy.

[0016] By the way, with the fine pitch in recent years, even in the case of strip-shaped objects, it may be possible to adjust the position of the drilling position with higher positional accuracy.

Even in such a case, by finely moving the drilling mechanism in one direction with respect to the base, the position adjustment of the drilling position in one direction of the drilling mechanism with respect to the strip-shaped workpiece can be adjusted with high accuracy. Can be done. For this reason, it becomes possible to drill a strip-shaped workpiece with higher positional accuracy.

[0017] Furthermore, in the drilling device of the present invention, the distance necessary for fine movement of the drilling mechanism along one direction is sufficient to adjust the position of the drilling position. The configuration for moving the camera in one direction can be made compact, resulting in Thus, it becomes possible to reduce the length of the punching device along the opening of the punching device, that is, along one direction. For this reason, the installation space and work space of the drilling device can be reduced.

[0018] In this specification, "strip-shaped workpiece" refers to a substantially rectangular workpiece including a square shape that does not necessarily mean only an elongated shape of the workpiece. Is meant.

[0019] (2) In the punching device according to (1), the punching mechanism is installed on a table that can move horizontally along the other direction with respect to the base, and the table It is preferable to be configured to be finely movable along the one direction.

With this configuration, the position adjustment of the punching position in the other direction of the strip-shaped workpiece can be performed with high accuracy by appropriately moving the table along the other direction.

[0021] (3) In the punching device according to (2), the punching mechanism corresponds to a mover that can advance and retreat along a direction having a component in the other direction, and the advancement and retraction of the mover. It is preferable to be installed on the table via a guide that can be finely moved in one direction.

[0022] With this configuration, the drilling mechanism can be finely moved along one direction, so that the position adjustment of the drilling position in one direction can be performed with high accuracy.

In addition, as a mechanism for finely moving the drilling mechanism in one direction, a compact mechanism is used in which the guide can move in one direction in response to the movement of the moving element. It is possible to reduce the length of the punching device. The guide may be a rail-shaped guide extending along a direction having a component in the other direction! /, And a groove-shaped guide formed along a direction having a component in the other direction. There may be.

[0024] With this configuration, the shape of the frame of the punching mechanism is not a shape that is closed to the part that supports the die mold and the punch mold. The length of the frame that supports the punching die only needs to be such that the punching mechanism can move at least the length of the strip-shaped workpiece in the other direction. For this reason, for example, it becomes possible to reduce the size of the punching mechanism as compared with the case of a die-shaped frame that supports the die mold and the punch mold at the center.

[0025] Further, by configuring in this way, if the frame is arranged along the other direction having mechanically sufficient rigidity, the accuracy of the drilling position due to the fluctuation of the drilling position caused by the movement of the drilling mechanism is improved. It is possible to reduce the decrease, and it is possible to perform drilling with high positional accuracy.

[0026] (5) In the punching device according to any one of (1) to (4), a strip-shaped workpiece is guided to both sides in the one direction of the two sets of workpiece feeding devices. It is preferable that a first work guide plate is installed, and a second work guide plate for guiding a strip-shaped workpiece is installed on both sides in the other direction of the punching die.

[0027] When the strip-shaped workpiece is rigid, the first work guide plate and the second work guide plate described above are not necessarily required. However, when the strip-shaped workpiece is flexible, when the strip-shaped workpiece is fed by one of the two workpiece feeding devices, The strip-shaped workpiece may be warped or undulated due to the fact that both ends in the other direction and one end in one direction of the strip-shaped workpiece are suspended by gravity. Even in such a case, by providing the work guide plate, it becomes possible to effectively suppress the warpage and undulation of the strip-shaped workpiece, and the strip-shaped workpiece is processed. This makes it possible to smoothly feed an object and to perform drilling on a strip-shaped workpiece with high positional accuracy.

[0028] In this case, the height of the upper surface of the first work guide plate and the second work guide plate is such that the surface force on the punching side of the die mold or punch mold is slightly (for example, 0.0050mn! ~ 2. Omm) It is preferable to set it at a distant position.

[0029] (6) In the punching device according to any one of (1) to (5), each of the two sets of workpiece feeding devices performs a workpiece feeding operation in each of the two sets of workpiece feeding devices. It is preferable to have a motor to be controlled, and to control the tension of the strip-shaped workpiece supplied between the two sets of workpiece feeding devices by controlling these motors.

[0030] With such a configuration, even when the strip-shaped workpiece is flexible, the strip-shaped workpiece is maintained in an appropriate state by maintaining the tension of the strip-shaped workpiece. It is possible to effectively suppress the occurrence of warping and undulation of the workpiece. This makes it possible to adjust the drilling position of the strip-shaped workpiece with high accuracy. For this reason, it becomes possible to drill a strip-shaped workpiece with higher positional accuracy.

[0031] With this configuration, the motor that controls the workpiece feeding operation also serves to control the tension of the strip-shaped workpiece, so that the configuration as a punching device is simplified.

[0033] With this configuration, even when the strip-shaped workpiece is flexible, the tension of the strip-shaped workpiece can be maintained in an appropriate state, and the strip-shaped workpiece can be maintained. It is possible to effectively suppress the occurrence of warpage and undulation of the object to be covered. As a result, the position of the piercing position in one direction of the piercing mechanism for the strip-shaped workpiece can be adjusted with high accuracy. For this reason, it becomes possible to drill a strip-shaped workpiece with higher positional accuracy.

Further, with this configuration, since the tension of the strip-shaped workpiece is controlled using two sets of work feeding devices, the configuration as a punching device is simplified.

[0034] It is preferable that the perforating apparatus according to (6) and (7) further includes a sensor for detecting the tension of the strip-shaped workpiece. For example, it is preferable that the punching device has a sensor that detects a load of a motor that controls a workpiece feeding operation, or a sensor that detects waviness of a strip-shaped workpiece. By configuring in this way, the rotation of the motor is controlled according to the detection result of the sensor, or the control device for controlling the interval between the two sets of workpiece feeding devices is controlled, so that the strip-shaped covering object is It becomes possible to control the tension of the object to be appropriate. [0035] (8) In the punching device according to any one of the above (1) to (7), the strip-shaped workpiece is supplied in a state where the upper rollers in the two sets of work feeding devices are moved upward. And having a structure that can be recovered.

It is possible to reduce the time loss that is required for recovery.

[0039] Further, with this configuration, since the workpiece supply / recovery device is installed above the punching mechanism, it is not necessary to secure a new space for the workpiece supply / recovery device. This also makes it possible to suppress the flat area of the punching device from becoming large.

[0040] (10) In the perforating apparatus according to (9), further comprising a supply stocker and a recovery stocker installed on both sides in the one direction of the base, the supply stocker and the recovery stocker include It is preferably movable along the other direction.

[0041] With this configuration, the worker moves the supply stocker and the recovery stocker along the other direction in the state of facing the front side of the perforating apparatus, that is, the side facing the perforation mechanism. Therefore, the workability for supplying and collecting the strip-shaped workpiece is improved.

[0042] (11) In the punching device according to any one of (1) to (10), the punching die may be a punching die having a stripper plate.

[0043] By configuring in this way, it is possible to prevent the strip-shaped workpiece from adhering to the punch of the punching die after the punching operation, so that the productivity of the punching operation is improved. [0044] (12) In the punching device according to any one of (1) to (10), the punching die has a half presser plate disposed above the strip-shaped workpiece. In the half-pressing plate, the distance between the half-pressing plate and the die plate in the die mold is set to a value within a range of 0.02 to 0.3 mm from the thickness of the strip-shaped workpiece. In this state, it may be a half presser plate that enables positioning of the drilling position and drilling.

[0045] According to this configuration as well, it is possible to prevent the strip-shaped workpiece from adhering to the punch of the punching die after the punching operation. Improve.

Also, with this configuration, the half-pressing plate suppresses warpage and waviness of the strip-shaped workpiece, and therefore it is possible to punch the strip-shaped workpiece with high positional accuracy.

Furthermore, this configuration makes it possible to punch a strip-shaped workpiece by the lifting / lowering operation of only the punch. Therefore, for punches having a stripper plate that requires the lifting / lowering operation of the punching die. Compared with the mold, the drilling operation can be performed at high speed. This makes it possible to increase the number of drilling operations per unit time and improve the productivity of drilling operations.

[0046] (13) In the punching device according to (12), the half presser plate is used when a strip-shaped workpiece is inserted between the punch mold and the die mold. It is preferable to be configured to be movable away from the die mold.

[0047] With this configuration, a strip-shaped workpiece can be quickly inserted between the punch mold and the die mold, so that the strip-shaped workpiece is processed. It is possible to reduce the time required to do this. In addition, it is possible to smoothly insert a strip-shaped workpiece between the punch mold and the die mold, thereby suppressing damage or damage to the strip-shaped workpiece. It is possible to improve the processing yield of strip-shaped workpieces.

[0048] (14) In the punching device according to the above (12) or (13), the half presser plate is transparent, and a first lighting device and a lower part of the die mold are below the die hole. Imaging It is preferable that a device is disposed, a second illumination device is disposed above the half-pressing plate, and the imaging device is capable of photographing a strip-shaped workpiece through the die hole.

[0049] With this configuration, the perforation position can be read by photographing the strip-like workpiece illuminated by the first illumination device and the Z or second illumination device with the imaging device. Become. This makes it possible to control the feed amounts of the two sets of workpiece feeders based on the read drilling positions, and to control the movement amount in the other direction and the movement amount in one direction of the drilling mechanism. The position adjustment of the drilling position can be performed with high accuracy.

[0050] Note that "below the die hole" is not limited to being almost directly below the die hole, and the strip-shaped workpiece may be illuminated or photographed below the die hole. An area that is possible. The term “above the half presser plate” refers to an area where a strip-like workpiece can be illuminated from above, which is not limited to being almost directly above the half presser plate.

[0051] (15) In the punching device according to any one of (11) to (13), the die mold has a shooting hole, and the die mold has a lower portion of the shooting hole. Includes a first illumination device and an imaging device, a second illumination device is disposed above the imaging hole in the die mold, and the imaging device passes through the imaging hole. It is preferable to be able to photograph strip-shaped workpieces.

[0052] With this configuration, it is possible to read the punching position by photographing the strip-shaped workpiece illuminated by the first illumination device and the Z or second illumination device with the imaging device. Become. This makes it possible to control the feed amounts of the two sets of workpiece feeders based on the read drilling positions, and to control the movement amount in the other direction and the movement amount in one direction of the drilling mechanism. The position adjustment of the drilling position can be performed with high accuracy.

It should be noted that “below the shooting hole” is not limited to being almost directly below the shooting hole, but is a strip-like shape through the shooting hole below the shooting hole in the die mold. An area where the object can be illuminated or photographed. Further, “above the shooting hole” is not limited to being almost directly above the shooting hole, but refers to an area where the shooting hole can be illuminated with an upward force.

In FIG. 1 to FIG. 3, the configuration for supporting and driving the two sets of workpiece feeding devices 210 and 220 is omitted.

[0065] As shown in Fig. 3, the two sets of workpiece feeding devices (first workpiece feeding device 210 and second workpiece feeding device 220) have upper rollers 212, 222 and lower rollers 214, 224, respectively. . Further, as shown in FIG. 5, the two sets of work feeding devices 210 and 220 move the upper rollers 212 and 222 in the two sets of work feeding devices 2 and 220 upward by the roller lifting mechanisms 216 and 226, respectively. It has a structure that enables supply and recovery of strip-shaped workpiece W in a state of being moved.

The upper roller 222 of the second workpiece feeding device 220 is moved downward to hold the strip-shaped load W with the upper roller 222 and the lower roller 224 (see FIG. 8 (d)). ;). Here, the drilling position adjustment in one direction (y-axis direction) is performed by operating two sets of workpiece feeders 210 and 220 in synchronism to move the strip-shaped workpiece W in one direction (y-axis direction). In addition, the drilling mechanism 400 is finely moved in one direction (y-axis direction). The drilling position adjustment in the other direction (X-axis direction) is performed by moving the drilling mechanism 400 in the other direction (X-axis direction).

[0075] When the end of the strip-shaped workpiece W is detached from the first workpiece feeder 210 while drilling the strip-shaped workpiece W, the drilling position adjustment in one direction (y-axis direction) is performed. For the adjustment, operate the second workpiece feeder 220 to feed the strip-shaped workpiece W in one direction (y-axis direction) and slightly move the drilling mechanism 400 in one direction (y-axis direction). (Refer to Fig. 8 (e).) ₀ Drilling position adjustment in the other direction (X-axis direction) is performed by moving the drilling mechanism 400 in the other direction (X-axis direction).

[0076] 3. Workpiece recovery process

When the punching of the strip-shaped workpiece W is completed (see FIG. 8 (f)), the upper roller 222 of the second workpiece feeding device 220 is moved upward, and the strip-shaped workpiece W is moved. Is released from the second workpiece feeder 220, and the processed strip-shaped workpiece W is recovered (see Fig. 8 (g);). Through the above process, a drilling operation is performed on the strip-shaped workpiece W.

[0077] For this reason, according to the punching device 100 according to the first embodiment, the strip-shaped workpiece W as a workpiece is fed by the two workpiece feeding devices 210 and 220 (advanced or moved along one direction) In addition, the strip-shaped workpiece W can be fed by either one of the two workpiece feeders 210 and 220. As a result, the front end portion of the strip-shaped workpiece W can be sent to the drilling position in a free state with both the front end portion and the rear end portion of the strip-shaped workpiece W being free. In addition, it is possible to perform perforation well at any end portion of the rear end portion.

Further, as shown in FIGS. 8 (c) and 8 (f), the front end portion and the rear end portion of the strip-shaped workpiece W are removed by a series of operations of the two sets of workpiece feeding devices 210 and 220. Since it can be sent to the drilling position, it is not necessary to perform the drilling work in two steps.

[0079] Furthermore, since the strip-shaped workpiece W can be grasped by the upper rollers 212 and 222 and the lower rollers 214 and 224, the strip-shaped workpiece W is clamped by a clamper. The operation to perform becomes unnecessary.

[0080] Therefore, according to the punching device 100 according to the first embodiment, the punching device can perform the punching operation over the entire surface of the strip-shaped workpiece W and with high productivity.

[0081] In the punching device 100 according to the first embodiment, as shown in Figs. 8 (a) to 8 (g), the punching position in one direction (y-axis direction) in the strip-shaped workpiece W By using two sets of work feeding devices that have upper rollers 212 and 222 and lower rollers 214 and 224, it is possible to sufficiently adjust the position of the strip-shaped workpiece W sufficiently. ing.

By the way, with the fine pitch in recent years, even in the case of the strip-shaped workpiece W, it may be possible to further adjust the position of the drilling position with higher positional accuracy.

Even in such a case, according to the piercing device 100 according to the first embodiment, the piercing mechanism 400 is finely moved along one direction (y-axis direction) with respect to the base 110 to thereby form a strip-like shape. It is possible to adjust the position of the drilling position in one direction (y-axis direction) of the drilling mechanism 400 with respect to the workpiece W with high accuracy. For this reason, it becomes possible to drill a strip-shaped workpiece W with higher positional accuracy.

In the drilling device 100 according to the first embodiment, as shown in FIG. 1, the drilling mechanism 400 is provided on a table 300 that can move horizontally along the other direction (X-axis direction) with respect to the base 110. is set up. As shown in FIG. 4, the table 300 is placed on the base 110 in the other direction (X-axis direction). It is installed so that it can move on rail 310 installed along the direction. The table 300 can be moved along the other direction (X-axis direction) by the motor 302 via the ball screw 304. In FIG. 4, the punching mechanism 400 on the table 300 is omitted.

[0084] Therefore, according to the punching device 100 according to the first embodiment, the position adjustment of the punching position in the other direction (X-axis direction) in the strip-shaped workpiece W is performed by moving the table 300 in the other direction (X It is possible to carry out with high accuracy by appropriately moving along the axial direction.

In the perforating apparatus 100 according to the first embodiment, as shown in FIGS. 9 (a) and 9 (b), the perforating mechanism 400 is installed on the table 300 via the fine movement mechanism 350. That is, the drilling mechanism 400 includes a movable element 370 that can advance and retreat in the other direction (X-axis direction) and a guide 380 that can be finely moved in one direction (y-axis direction) in response to the advancement and retraction of the movable element 370. It is installed in the table 300. The shaded portion in FIG. 9 (b) shows the mover 370.

[0086] As shown in FIGS. 9 (c) and 9 (d), the fine movement in one direction (y-axis direction) of the punching mechanism 400 is caused by a moving element 370 force driven by a motor 352 via a ball screw 354. This is done by slightly moving the guide 380 in one direction while moving along the guide 380. FIG. 8 (c) shows a state where the ball screw 354 is pulled out, and shows a state where the punching mechanism 400 is finely moved to the second roller side 220. FIG. FIG. 9 (d) shows a state where the ball screw 354 is fully retracted, and shows a state where the punching mechanism 400 is slightly moved toward the first workpiece feeder 210 side.

[0087] Therefore, according to the drilling device 100 according to the first embodiment, the guide 380 finely moves in the-direction (y-axis direction) corresponding to the moving element 370 that moves forward and backward along the rail 310. The position adjustment in one direction (y-axis direction) of the drilling mechanism 400 can be performed with high accuracy.

Also, as a mechanism for finely moving the drilling mechanism 400 in one direction (y-axis direction), a compact mechanism is used in which the guide 380 can move in the negative direction (y-axis direction) in response to the advancement and retraction of the slider 370. Therefore, it is possible to reduce the length of the perforation apparatus 100 along the front end of the perforation apparatus 100, that is, along one direction (y-axis direction).

Note that the guide is the other like the guide 380 in the perforating apparatus 100 according to the first embodiment. It may be a rail-shaped guide extending along a direction having a directional component, or may be a groove-shaped guide formed along a direction having a directional component.

In the punching device 100 according to the first embodiment, as shown in FIG. 1, the punching mechanism 400 includes a U-shaped frame 410, and one end of the U-shaped frame 410 is provided at one end. Then, the die mold 510 is supported, and the punch mold 520 is supported at the other end of the U-shaped frame 410.

For this reason, according to the punching device 100 according to the first embodiment, the shape of the frame of the punching mechanism 400 is not a closed shape in the portion that supports the die mold 510 and the punch mold 520. Therefore, the length of the frame 410 that supports the die mold 510 and the punch mold 520 is such that the punching mechanism 400 can move at least by the length in the other direction of the strip-shaped workpiece W (X-axis direction). Any length is sufficient. For this reason, for example, it becomes possible to reduce the size of the punching mechanism as compared with the case of a mouth-shaped frame that supports the die mold 510 and the punch mold 520 at the center. .

[0090] Further, according to the punching device 100 according to the first embodiment, the U-shaped frame 410 is disposed along the other direction (X-axis direction) having mechanically sufficient rigidity. It is possible to reduce the deterioration of the drilling position accuracy due to the fluctuation of the drilling position caused by the movement of the drilling mechanism 400, and it is possible to perform drilling with high position accuracy.

[0091] In the punching device 100 according to the first embodiment, as shown in Fig. 7 (a), strip-shaped coverings are provided on both sides in one direction (y-axis direction) of the two sets of workpiece feeding devices 210 and 220. The first workpiece guide plates 250 and 260 are installed to guide the workpiece W, and the second workpiece that guides the strip-shaped workpiece W on both sides in the other direction (X-axis direction) of the punching die 500 Guide plates 230 and 240 are installed.

[0092] When the strip-shaped load W is rigid, the work guide plates 230, 240, 250, 260 described above are not necessarily required. However, when the strip-shaped workpiece W is flexible, when the strip-shaped workpiece W is fed by one of the two workpiece feeders 210 and 220, In the strip-shaped workpiece W, both ends in the other direction (X-axis direction) and one-side end (y-axis direction) hang down due to gravity, resulting in a strip-shaped workpiece W. Warpage and undulation may occur (see Fig. 7 (b);). This Even in such a case, by providing the work guide plates 230, 240, 250, 260, as shown in Fig. 7 (c), it is possible to effectively generate warpage and undulation of the strip-shaped workpiece W. The strip-shaped workpiece W can be smoothly fed, and the strip-shaped workpiece W is drilled with high and positional accuracy. Is possible.

In the perforating apparatus 100 according to the first embodiment, as shown in FIGS. 10 (a) to 10 (d), each of the two sets of workpiece feeding devices 210 and 220 includes two sets of workpiece feeding devices 210. , 220 have motors 217, 227 for controlling the workpiece feeding operation in each of them, and are driven via belts 218, 228. The two sets of workpiece feeders 210 and 220 can control the tension of the strip-shaped workpiece W supplied between the two sets of workpiece feeders 210 and 220 by controlling these motors 217 and 227. Become! /

[0094] Control of the tension of the strip-shaped object W is performed as follows, for example. First, a strip-shaped workpiece W is fed in one direction (y-axis direction) by the first workpiece feeder 210 (see FIG. 10 (a);). When the strip-shaped workpiece W reaches the second workpiece feeder 220 (see FIG. 10 (b)), the upper roller 222 of the second workpiece feeder 220 moves downward to move the strip-shaped workpiece. Hold the workpiece W (see Fig. 10 (c);). The first workpiece feeder 210 is stopped, and the second workpiece feeder 220 is operated to feed the strip-shaped workpiece W in one direction (see FIG. 10 (d);). By controlling the motors 217 and 227 in this way, the tension of the strip-shaped workpiece W supplied between the two sets of workpiece feeding devices 210 and 220 is controlled.

[0095] For this reason, according to the punching device 100 according to the first embodiment, even when the strip-shaped workpiece is flexible, the tension of the strip-shaped workpiece W is appropriately set. By maintaining a stable state, it is possible to effectively suppress the warpage and undulation of the strip-shaped workpiece W. This makes it possible to adjust the drilling position for the strip-shaped workpiece W with high accuracy. For this reason, it becomes possible to make a hole in the strip-shaped load W with higher positional accuracy.

[0096] Also, for this reason, according to the punching device 100 according to the first embodiment, the motors 217 and 227 for controlling the workpiece feeding operation are also used for controlling the tension of the strip-shaped workpiece W. The structure as a drilling device is simplified. Note that the first workpiece feeding device 210 is stopped as described above, and the second workpiece feeding device 220 is operated in the direction in which the strip-shaped workpiece W is fed in one direction. In addition to the method of controlling the tension of the workpiece W, the strip-shaped workpiece is moved by operating the first workpiece feeder 210 and the second workpiece feeder 220 in the direction in which the strip-like workpiece W is pulled. A method of controlling the tension of W is used, or the second work feeding device 220 is stopped, and the first work feeding device 210 is operated in the direction opposite to the work feeding direction to move the strip-shaped force You can use a method to control the tension of the object W.

[0098] It is preferable that the perforating apparatus 100 according to the first embodiment further includes a sensor that detects the tension of the strip-shaped workpiece W. For example, the two sets of workpiece feeding devices 210, 220 may be configured to have sensors that detect the load of the motors 217, 227 that control the workpiece feeding operation, and the strip-shaped workpiece W may be warped or undulated. If it is configured to have a sensor to detect, the rotation of the motors 216 and 226 is controlled according to the detection result of the sensor, so that the tension of the strip-shaped object W is controlled appropriately. It becomes possible to do.

In the punching device 100 according to the first embodiment, as shown in FIGS. 8 (a) and 8 (g), the upper rollers 212 and 222 in the two sets of workpiece feeding devices 210 and 220 are connected to a roller lifting mechanism 216. , 226, so that the strip-shaped workpiece W can be supplied and recovered while being moved upward. When the strip-shaped workpiece W is supplied to the first workpiece feeding device 210, the upper roller 212 of the first workpiece feeding device 210 is moved upward, and the upper roller 212 of the first workpiece feeding device 210 is moved. A strip-shaped workpiece W is supplied between the lower roller 214 and the lower roller 214 (see FIG. 8 (a).) ₀ When collecting the strip-shaped workpiece W, The roller 222 is moved upward to collect the strip-shaped load W (see Fig. 8 (g)).

It is possible to carry out positioning and drilling of the drilling position in the enlarged state.

[0102] Therefore, according to the punching device 100 according to the first embodiment, it is possible to prevent the strip-shaped workpiece W from adhering to the punch 522 of the punching die 520 after the punching operation. The productivity of drilling work is improved.

[0103] Further, according to the punching device 100 according to the first embodiment, the half presser plate 524 suppresses warpage and undulation of the strip-shaped workpiece W, so that the strip-shaped workpiece is punched with high positional accuracy. It becomes possible to carry out holes.

[0104] Furthermore, according to the punching device 100 according to the first embodiment, it is possible to punch the strip-shaped workpiece W by the lifting and lowering operation of only the punch 522. Compared with a punching die having a stripper plate that needs to move up and down, the punching operation can be performed at a higher speed. For this reason, it becomes possible to increase the number of times of drilling per unit time, and the productivity of the drilling work is improved.

In the punching device 100 according to Embodiment 1, as shown in FIGS. 11 (a) to 11 (c), the half presser plate 524 is provided between the punch die 520 and the die die 510. When a strip-shaped object W is inserted into the container, it can be retracted upward.

[0106] That is, the first workpiece feeder 210 feeds the strip-shaped workpiece W in the negative direction (y-axis direction) (see Fig. 11 (a)), and the punching die 500 has a punching die. When the strip-shaped object W is inserted between the die 520 and the die die 510, the half presser plate 524 is retracted upward by the half presser plate lifting pin 526 (FIG. 11 ( See b);). When a strip-shaped workpiece W is inserted between the punch mold 520 and the die mold 510, the half presser plate 524 is removed from the die mold 520 by the half presser plate lifting pin 526.

By this, it becomes possible to read the drilling position of the strip-shaped load W. For this reason, the feed amount of the two sets of workpiece feeding devices 210 and 220 is controlled based on the read drilling position, the amount of movement of the drilling mechanism 400 in the other direction (X-axis direction), and one direction (y-axis direction). This makes it possible to control the amount of movement of the drilling hole and to adjust the position of the drilling position with high accuracy.
