Description

The present invention relates to a press working apparatus.

Conventionally, there is a processing method in which an external force is applied to a plate, a pipe, or the like by press working or die forming to cause plastic deformation or separation to obtain a work piece having a desired shape and size.
Of these, press working is highly productive, easy to operate, and easy to mechanize and automate.
This is because the press work is performed by a punching die and a press device, and the number of strokes of a normal press machine reaches several tens of times per minute, and with high-speed pressurization, it reaches hundreds or thousands of times per minute, and once. This is because punching can be performed for each press stroke.

In press working, the dimensions and shape of the work piece are highly accurate, and in general, the quality of the work piece is stable, and the same work can be processed in large quantities with high accuracy, so that the workability is good.
Pressing can process parts with large and complicated shapes such as watches, stopwatches, vertical beams of automobiles, and coverings, and the strength after processing is increased due to the cold deformation and hardening effect of the material during processing. It has the advantage of high rigidity.
Stamping is a resource-saving and energy-saving processing method. Generally, it does not generate chips, consumes less material, and does not require any heating equipment, so the cost of the work piece should be kept low. There is also an advantage that it can be done.

However, in the press working of a strip-shaped material such as a steel plate, since the strip-shaped material is wound on a winding roll, a certain arch-shaped bending (arc) occurs in the strip-shaped material before processing due to the winding roll. Will end up.
Therefore, if the strip-shaped material is pressed while this bending occurs, the punching head cannot effectively press the strip-shaped material, the processing quality deteriorates, and the operating rate of the strip-shaped material decreases. There is.

In order to solve this, a processing device for flattening the strip-shaped material wound on the take-up roll is required before the press working.
For example, in Patent Document 1, in an extruded product in which a core material bent by roll molding into a U-shaped cross section is embedded, the surface of the portion where the core material is embedded is not flat and the surface is uneven. The core material rolls in a U-shaped cross section to solve the problem that it may occur or a part of the core material may be exposed to the outside, which may impair the appearance (decorativeness) of the extruded product. An invention that can prevent a defect due to torsional deformation of a core material piece when being bent by molding is disclosed.

According to the present invention, before the core material is bent by roll forming into a U-shaped cross section, the core material is pre-twisted and a piece of the core material is twisted and plastically deformed in a specific direction in advance. After that, when the core material is roll-formed into a U-shaped cross section, the twisted deformation of the core material piece cancels or corrects the torsional plastic deformation of the core material piece due to the preliminary twisting, and the core It can be processed so that the widthwise ends of the piece of material are aligned in the longitudinal direction.

However, the invention according to the same document is to twist and plastically deform the core material pieces in a specific direction in advance in order to avoid a step between the edges of the core material pieces adjacent to each other in the longitudinal direction. , At least one of the downstream side in the moving direction and the upstream side in the moving direction during bending of the core material piece is displaced in the thickness direction of the core material in the direction relatively opposite to the other side. It means to process, and does not straighten the strip itself flat.

A connecting port A31 is formed inside the sliding body B30, and the oil inlet B28 and the oil outlet B27 are in a state of communicating with the connecting port A31 in accordance with the movement of the sliding body B30.
In accordance with the movement of the sliding body B30, the connecting port A31 of the sliding body B30 is in a state of communicating with the oil inlet B28 and the oil outlet B27, so that the press roller of the cylinder A12 by the sliding cylinder A26 described above A hydraulic adjustment mechanism that pushes down the A20 is realized.

That is, when the strip-shaped member 92 that has passed through the cylinder A12 is bent and not leveled flatly, the press roller B34 of the sliding cylinder A26 is pushed up by the bent strip-shaped member 92, and as a result, the push rod B32 At the same time, the sliding body B30 is also pushed up, and the connecting port A31 of the sliding body B30 is in a state of communicating with the oil inflow port B28 and the oil outflow port B27. At this time, the hydraulic oil flowing in from the oil pipe C38 is the oil inflow port. It flows from B28 through the connecting port A31 to the oil outlet B27, flows into the cylinder A12 through the oil pipe B61, and the hydraulic oil of the hydraulic oil pushes down the sliding body A15 of the cylinder A12 and presses it together with the push rod A17.

The oil inlet B28 is connected to the cylinder B40 attached by two fixed shafts A62 to the outside of the housing 10 via the oil pipe C38.
As shown in FIG. 9, the cylinder B40 houses a sliding body C49 inside, and the sliding body C49 slides in the cylinder B40.
A limit ring A46 and a limit ring B47 that limit the sliding range of the sliding body C49 are attached to the cylinder B40.
A fixing ring 48 is provided on the cylinder B40, and a spring C52 is attached between the fixing ring 48 and the sliding body C49.
The sliding body C49 slides in the cylinder B40 between the limit ring A46 and the limit ring B47 by the elastic force of the spring C52.

An oil outlet C42 is formed on one side surface of the cylinder B40, and the cylinder B40 is connected to the oil inlet B28 of the sliding cylinder A26 via an oil pipe C38.
An oil inflow port C41 is formed on the other side surface of the cylinder B40, and the cylinder B40 is connected to an external hydraulic device via an oil pipe E60.
Therefore, the tip of the oil pipe E60 is connected to an external hydraulic device.

Two oil outlets D44 and two oil inlets D43 are symmetrically formed on the upper surface and the lower surface of the cylinder B40.
The oil inlet D43 and the oil outlet D44 are connected to each other via an oil pipe D53 on the upper surface side and the lower surface side, respectively.

As shown in FIG. 10, a reset port 45 is formed on the upper surface of the cylinder B40.
As shown in FIG. 9, a sliding cylinder B54 is connected to the reset port 45, and the sliding body D56 that slides vertically and vertically inside the sliding cylinder B54 and the sliding body D56 are slid by elastic force. A spring D58 for moving is housed.
A seal ring B57 is attached to the sliding body D56.
As shown in FIG. 12, the sliding cylinder B54 is provided with a ventilation port B55 at the upper end and a limit ring C59 for limiting the sliding range of the sliding body D56.
The sliding body C49 is formed with a connecting port C51 penetrating in the vertical vertical direction, and a communication port B50 communicating from the connecting port C51 to the space on the oil pipe E60 side.

The role of the cylinder B40 is to regulate the pressure of the hydraulic oil flowing in from the external hydraulic device connected to the oil pipe E60.
When hydraulic oil flows into the cylinder B40 from an external hydraulic device via the oil pipe E60, the sliding body C49 slides in the cylinder B40.
At this time, the sliding body C49 is pushed toward the left side of the drawing of FIG. 9 until the connecting port C51 formed so as to penetrate the sliding body C49 in the vertical vertical direction communicates with the oil outlet D44.
Then, when the connecting port C51 communicates with the oil outlet D44, the hydraulic oil in the cylinder B40 flows from the communication port B50 through the connecting port C51 and from the oil outlet D44 into the oil pipe D53, and the oil inlet D43 flows through the cylinder B40. It returns to the inside and flows into the sliding cylinder A26 from the oil outlet C42 through the oil pipe C38.

When the press processing device is in operation, the control valve 22 is closed, so that the hydraulic oil that has flowed into the sliding cylinder A26 is in the position of the press roller B34 of the sliding cylinder A26 in the vertical downward direction in the initial state. When the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped member 92, it does not flow into the sliding cylinder A26, and the sliding body B30 together with the press roller B34 and the push rod B32. Is pushed up, the connecting port A31 of the sliding body B30 is in a state of communicating with the oil inlet B28 and the oil outlet B27, and the hydraulic oil flowing from the oil pipe C38 passes through the connecting port A31 from the oil inlet B28. It flows to the outflow port B27, flows into the cylinder A12 through the oil pipe B61, and as a result of pushing down the sliding body A15 of the cylinder A12 by the hydraulic pressure of the hydraulic oil, the press roller A20 is also pushed down together with the push rod A17.
As a result, the press roller A20 can straighten the bent strip-shaped member 92 with a stronger force and level it flat.

If the strip-shaped member 92 that has passed through the cylinder A12 is leveled flat, the positions of the press roller B34 and the support roller B36 of the sliding cylinder A26 do not change, but the strip-shaped member 92 that has passed through the cylinder A12 is bent. If it is not leveled flat as it is, the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped member 92, and the hydraulic oil is sent from the sliding cylinder A26 to the cylinder A12. The press roller A20 is pushed down by the force, and the bent strip 92 is straightened and leveled flat.
That is, when the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped member 92, the hydraulic oil is sent from the sliding cylinder A26 to the cylinder A12, so that the hydraulic oil in the cylinder B40 is increased accordingly. Flows into the sliding cylinder A26, but the pressure in the vicinity of the oil outlet C42 in the cylinder B40 becomes negative. Therefore, the sliding body C49 reaches a position where the connecting port C51 of the sliding body C49 communicates with the oil outlet D44. Slides to the left side of the drawing of FIG.

When the hydraulic oil does not flow into the cylinder A12, it does not flow into the sliding cylinder A26. Therefore, the hydraulic oil in the vicinity of the oil outlet C42 of the cylinder B40 becomes high, and the sliding body C49 is shown in FIG. By being pushed back to the right, the sliding body C49 moves to a position where the connecting port C51 does not communicate with the oil outlet D44.
By this mechanism, the hydraulic oil is sent from the sliding cylinder A26 to the cylinder A12 only when the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip 92, and as a result, the press roller A20 Is pushed down by the hydraulic pressure, and the bent strip-shaped member 92 can be straightened and leveled flat.

In this way, the sliding body C49 slides in the cylinder B40 to adjust the amount of hydraulic oil flowing into the sliding cylinder A26.
Further, a sliding cylinder B54 is connected to the cylinder B40, and the sliding body D56 slides in the sliding cylinder B54.
The sliding of the sliding body D56 also plays a role of adjusting the inflow amount of the hydraulic oil into the sliding cylinder A26.

That is, even if a large amount of hydraulic oil flows in from the external hydraulic device connected to the oil pipe E60, the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped material 92 and slides. Unless the connecting port A31 of the moving body B30 communicates with the oil inlet B28 and the oil outlet B27, the hydraulic oil does not flow from the cylinder B40 into the sliding cylinder A26, so that a large amount of hydraulic oil flows in. Then, the oil is stored in the vicinity of the oil pipe E60 of the cylinder B40, and the oil pressure becomes high. However, by pushing the sliding body D56 toward the upper side of the drawing of FIG. Can be suppressed.
The cylinder B40 and the sliding cylinder B54 each contain a spring C52 and a spring D58, and each of the sliding body C49 and the sliding body D56 is slid by an elastic force to return to the original position.

As shown in FIG. 1, a support I91, a support A2, and a support F73 are attached to the base 1.
A take-up roller A4 is attached to the support A2, and a take-up roller B87 is attached to the support I91.

As shown in FIG. 7, an arcuate block A74 is attached to the support F73 via the support G81.
An L-shaped rod 75 is rotatably attached to the support F73 around a swing pin 76.
An arc block B77 is attached to one end side of the L-shaped rod 75.
The arc block B77 sandwiches the strip-shaped member 92 so as to overlap the arc block A74.
The arc block B77 and the arc block A74 strongly sandwich the strip-shaped member 92 to form an arch-shaped bend in the strip-shaped member 92, facilitating winding of the strip-shaped member 92 by the take-up roller B87.
The L-shaped rod 75 is connected to the crank wheel 80 on the other end side via a connecting rod 78.

The connecting rod 78 is attached to the rotatable crank wheel 80 by a crank pin 79.
Therefore, the L-shaped rod 75 swings around the swing pin 76 in accordance with the rotation of the crank wheel 80, and the arc block B77 overlaps with the arc block A74.
On the support body F73, a bevel gear F82 attached to the tip of the rotation shaft of the crankwheel 80 on the back surface of the crankwheel 80 meshes with the bevel gear E83 connected to the drive module C84.
As a result, the output of the drive module C84 is transmitted to the crank wheel 80.

As shown in FIG. 5, a support H86 to which a guide roller 85 for guiding the strip 92 is attached is connected to the support I91.
The guide roller 85 is located between the arc block A74 and the take-up roller B87, and the take-up roller B87 is rotatably attached to the support I91.
A structure for forming an arch-shaped deflection in the strip-shaped member 92 is referred to as an arch forming mechanism.

As shown in FIG. 4, a bevel gear H88 attached to the back surface of the take-up roller B87 at the tip of the rotation shaft of the take-up roller B87 meshes with the bevel gear G89 connected to the drive module D90 on the support I91.
As a result, the output of the drive module D90 is transmitted to the take-up roller B87.

As shown in FIG. 5, the support A2 is connected to the support B3 to which two pinch rollers A5 located side by side in the vertical vertical direction are attached.
As shown in FIG. 2, the bevel gear B7 attached to the tip of the shaft A6 of the pinch roller A5 meshes with the bevel gear A8 connected to the drive module A9 on the back surface of one of the pinch rollers A5.
As a result, the output of the drive module A9 is transmitted to the pinch roller A5.

As shown in FIG. 1, the support I91 is connected to the support E72 to which two pinch rollers B67 located side by side in the vertical vertical direction are attached.
As shown in FIG. 3, the bevel gear D69 attached to the tip of the shaft B68 of the pinch roller B67 meshes with the bevel gear C70 connected to the drive module B71 on the back surface of one of the pinch rollers B67.
As a result, the output of the drive module B71 is transmitted to the pinch roller B67.

The drive module A9, the drive module B71, the drive module C84, and the drive module D90 are all composed of a motor, a speed reducer, and a control device.

The two pinch rollers A5 pull the strip 92 wound around the take-up roller A4.
The two pinch rollers B67 facilitate good winding of the strip 92 by the take-up roller B87.
The rotation of the take-up roller A4 has a constant damping effect, and the rotation speed is equal to the moving speed of the strip 92 pulled by the two pinch rollers A5.
As a result, the strip-shaped body 92 is in a tense state before being inserted into the widening mechanism 94, and is smoothly and stably pulled from the take-up roller A4 without falling off from the take-up roller A4.

The method of using the press working apparatus according to the present invention is as follows.

In the initial state, a strip-shaped member 92 having a sufficient length is wound around the take-up roller A4.
The vertical vertical distance between the press roller A20 and the support roller A93 is equal to the thickness of the strip 92.
The vertical vertical distance between the press roller B34 and the support roller B36 is equal to the thickness of the strip 92.
The sliding body A15 is arranged at an intermediate position of the cylinder A12.
The sliding body B30 is arranged at the lower end position of the sliding cylinder A26.
The spring A18 is in a pulled state and the spring B35 is in a compressed state.
In the initial state, the connecting port A31 of the sliding body B30 does not communicate with the oil outlet B27 and the oil inlet B28 formed on the side wall of the sliding cylinder A26.

The sliding body C49 of the cylinder B40 is arranged at a position where the two oil outlets D44 are closed.
In the initial state, the connecting port C51 formed in the sliding body C49 does not communicate with the oil outlet D44.
The sliding body C49 is arranged at a position where it is in contact with the limit ring A46, and is therefore separated from the limit ring B47.
The spring C52 is in an uncompressed state.
The sliding body D56 of the sliding cylinder B54 is arranged at a position close to the vent B55 at the upper end.
The spring D58 is in a compressed state.

The arc block A74 is in a state of being separated from the arc block B77.
The vertical vertical distance between the two pinch rollers A5 is equal to the thickness of the strip 92.
The vertical vertical distance between the two pinch rollers B67 is equal to the thickness of the strip 92.

To press the strip 92, first, the end of the strip 92 wound around the take-up roller A4 is passed through the two pinch rollers A5, and the inside of the housing 10 is inserted through the insertion port 11 of the housing 10. ..
Then, it is inserted between the press roller A20 and the support roller A93 and between the press roller B34 and the support roller B36 from the insertion port 11 of the housing 10 to the outside of the housing 10.
Further, it passes between the punch 66 and the press table 64, between the two pinch rollers B67, between the arc-shaped block A74 and the arc-shaped block B77, and is wound around the take-up roller B87 via the guide roller 85. ..

The drive module A9, the drive module B71, the drive module C84, and the drive module D90 control the press working apparatus according to the present invention.
That is, at the moment when the punch 66 makes a hole in the band-shaped material 92 or processes the strip-shaped material 92 into unevenness, all the drive modules stop all at once, the transfer of the band-shaped material 92 is stopped, and the punch 66 makes a hole in the band-shaped material 92. Or, when the processing to be uneven is completed, all the drive modules resume driving all at once, and the strip-shaped member 92 is transferred.
The drive module realizes the intermittent transfer of the strip 92.

When the press working apparatus according to the present invention is started, the control valve 22 is closed.
From an external hydraulic device connected to the oil pipe E60, hydraulic oil flows into the cylinder B40 via the oil pipe E60.
Further, when the hydraulic oil continues to flow into the cylinder B40 under pressure and the sliding body C49 is pushed toward the left side of the drawing of FIG. 9, the space between the sliding body C49 and the oil inflow port C41 gradually increases. Therefore, the spring C52 has a large elastic force due to compression.
Further, the sliding body D56 in the sliding cylinder B54 is also pushed toward the upper side of the drawing of FIG. 9, and the spring D58 has a large elastic force due to compression.
The upper space of the sliding body A15 in the cylinder A12 is filled with hydraulic oil in advance.

The drive module A9 drives the bevel gear A8 to rotate one pinch roller A5 via the bevel gear B7 and the shaft A6, and also rotates the other pinch roller A5.
As a result, the strip-shaped material 92 sandwiched between the two pinch rollers A5 is pulled out from the take-up roller A4.
Then, the strip-shaped member 92 is stretched by two pinch rollers A5 to correct the bending of the strip-shaped member 92.

The strip-shaped body 92 whose bending is corrected by the two pinch rollers A5 is inserted into the housing 10 from the insertion port 11 of the housing 10, and is between the press roller A20 and the support roller A93, and the press roller B34 and the support roller B36. It is transferred from the insertion port 11 of the housing 10 to the outside of the housing 10 through the spaces.
During that time, the band-shaped body 92 is corrected in bending by each of the press roller A20 and the support roller A93, and the press roller B34 and the support roller B36.
Specifically, the cylinder A12 pushes the press roller A20 vertically downward, straightens the bent strip-shaped member 92 with the support roller A93, and evens it flat.
After that, the strip-shaped body 92 is similarly flattened between the press roller B34 and the support roller B36 by correcting the bent strip-shaped member 92.
However, when the strip-shaped member 92 is not leveled flatly, the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped member 92, and the hydraulic oil is transferred from the sliding cylinder A26 to the cylinder A12. As a result of being fed, the press roller A20 is pushed down by the hydraulic pressure, and the bent strip-shaped member 92 is straightened and leveled flat.

That is, when the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip-shaped member 92, hydraulic oil flows from the sliding cylinder A26 into the cylinder A12, and the operation in the cylinder B40 is increased accordingly. Oil flows into the sliding cylinder A26, but the pressure in the vicinity of the oil outlet C42 in the cylinder B40 becomes negative. Therefore, the sliding body reaches a position where the connecting port C51 of the sliding body C49 communicates with the oil outlet D44. C49 slides to the left side of the drawing of FIG.
When the hydraulic oil does not flow from the sliding cylinder A26 into the cylinder A12, it does not flow into the sliding cylinder A26. Therefore, the hydraulic oil in the vicinity of the oil outlet C42 of the cylinder B40 becomes high, and the sliding body C49 Is pushed back to the right in FIG. 9, and the sliding body C49 slides to a position (original position) where the connecting port C51 does not communicate with the oil outlet D44.

By this mechanism, the hydraulic oil is sent from the sliding cylinder A26 to the cylinder A12 only when the press roller B34 of the sliding cylinder A26 is pushed up vertically by the bent strip 92, and as a result, the press roller A20 Is pushed down by the hydraulic pressure, and the bent strip-shaped member 92 can be straightened and leveled flat.
In this way, the sliding body C49 slides in the cylinder B40, so that the amount of hydraulic oil flowing into the sliding cylinder A26 can be adjusted.
Further, a sliding cylinder B54 is connected to the cylinder B40, and the sliding body D56 slides in the sliding cylinder B54.
The sliding of the sliding body D56 also plays a role of adjusting the inflow amount of the hydraulic oil into the sliding cylinder A26.

In the initial state, the sliding body A15 is arranged at an intermediate position of the cylinder A12 and closes the oil outlet A14. Therefore, the hydraulic oil in the cylinder A12 causes the oil pipe B61 by the closed control valve 22. Although there is a possibility of backflow to the sliding cylinder A26 via the oil pipe B61, the check valve 25 on the oil pipe B61 prevents the hydraulic oil in the cylinder A12 from flowing back to the sliding cylinder A26 via the oil pipe B61. ..
Therefore, the press roller A20 is not pushed up by the bending of the strip-shaped member 92 transferred on the support roller A93.
That is, the press roller A20 can strongly correct the bending of the strip-shaped member 92 transferred on the support roller A93.

If the press roller A20 cannot correct the bending of the strip-shaped material 92 transferred on the support roller A93, the strip-shaped material 92 transferred on the support roller B36 makes the press roller B34 vertical. By pushing it upward, the press roller A20 can press the strip-shaped member 92 more strongly by the action of the adjustment mechanism by the hydraulic pressure, and the bending of the strip-shaped member 92 can be corrected.
In particular, in the strip-shaped material 92, as the winding diameter of the strip-shaped material 92 wound around the take-up roller A4 decreases, the curvature of the deflection increases, so that stronger correction is required. Then, the press roller A20 can press the strip-shaped member 92 more strongly to correct the bending of the strip-shaped member 92.

Further, there is a concern that the press roller A20 pushes down the strip-shaped member 92 more than necessary due to the hydraulic pressure of the hydraulic oil flowing into the cylinder A12.
However, when the press roller A20 is lowered in the vertical downward direction, the sliding body A15 also slides downward in the cylinder A12, but the control valve 22 is opened with the upper space of the cylinder A12 communicating with the oil outlet A14. By letting the hydraulic oil flow out into the oil tank 24 through the oil pipe A23, the oil pressure of the hydraulic oil flowing into the cylinder A12 can be lowered.
As a result, the sliding body A15 is arranged at an intermediate position of the cylinder A12, the sliding body A15 closes the oil outlet A14, and the press roller A20 returns to the original position, so that the strip-shaped material is transferred on the support roller A93. The pressing force of the press roller A can be controlled so that the 92 is not corrected more than necessary.
After that, by closing the control valve 22 again, the press roller A20 can press the strip-shaped member 92 more strongly by the action of the adjustment mechanism by the flood control, and the bending of the strip-shaped member 92 can be corrected.

The strip-shaped member 92, which is transferred from the insertion port 11 of the housing 10 to the outside of the housing 10 and whose bending is corrected by the widening mechanism 94, is pressed on the press table 64.
The punch 66 attached to the support arm 65 punches the strip-shaped member 92 on the press table 64 in a state where all the drive modules are stopped all at once.
At the moment when the punch 66 makes a hole in the band-shaped material 92 or processes it into an uneven shape, all the drive modules are stopped all at once, the transfer of the band-shaped material 92 is stopped, and the drive module is intermittently transferred of the band-shaped material 92. To realize.
The punch 66 is formed by making a hole in the strip-shaped material 92 or processing it into an uneven shape.
When the punch 66 makes a hole in the strip-shaped member 92 or finishes processing the strip-shaped member 92 into unevenness, all the drive modules resume driving all at once, and the strip-shaped member 92 is transferred.

The drive module B71 drives the bevel gear C70 to rotate one pinch roller B67 via the bevel gear D69 and the shaft B68, and also rotates the other pinch roller B67.
As a result, the two pinch rollers B67 are pulled by sandwiching the strip-shaped member 92 which has been punched by the punch 66 or processed into unevenness, and the strip-shaped member 92 is transferred while being sandwiched from above and below, so that the burr of the strip-shaped member 92 is formed. The strip-shaped material 92 is transferred while smoothing the unevenness.

The drive module C84 drives the bevel gear E83 to rotate the crank wheel 80 via the bevel gear F82.
The crank wheel 80 swings the L-shaped rod 75 with the swing pin 76 as a fulcrum via the connecting rod 78 connected to the crank pin 79.
As the L-shaped rod 75 swings, the arc block B77 at the tip of the L-shaped rod 75 repeatedly approaches and separates from the arc block A74.
The strip-shaped member 92 passing between the arc block A74 and the arc block B77 flexes in an arc shape so that the arc block B77 approaches the arc block A74 and has the same curvature as the arc block B77 and the arc block A74. It is pressed like a circle.

The drive module D90 drives the bevel gear G89 to rotate the take-up roller B87 via the bevel gear H88.
As a result, the take-up roller B87 winds up and collects the strip-shaped material 92 that has been forcibly pressed so as to bend.
Since the strip-shaped body 92 is pressed into a bent shape by the arc block B77 and the arc block A74, it is easily wound by the take-up roller B87, and the take-up efficiency of the take-up roller B87 is improved.
As a result, the operating rate of the take-up roller B87 is improved, and the take-up roller B87 can wind a large number of strips 92.

The above-mentioned transfer of the strip-shaped member 92 is performed by intermittently repeating driving and stopping by the driving module A9, the driving module B71, the driving module C84, and the driving module D90.
The interval between driving and stopping is the same as the interval at which the punch 66 is machined into holes or irregularities formed in the strip 92.
That is, if the stop interval is short, the interval for the punch 66 to make a hole or unevenness in the band-shaped material 92 is short, and if the stop interval is long, the interval for the punch 66 to make a hole or unevenness in the band-shaped material 92 is short. Becomes longer.
