Specifically, a pair of corrugated gears that sandwich and corrugate a thin plate material are provided with a plurality of types having different gear tooth shapes, a rotational driving means that rotationally drives the pair of corrugated gears, and the plurality of types of waves. A corrugated material manufacturing apparatus comprising a gear switching means for switching a corrugated gear, and a corrugated thin plate sandwiched between the pair of corrugated gears and corrugated to the thin plate material, at the time of the previous corrugating process A multi-directional corrugating material can be manufactured by performing corrugation processing in a direction intersecting with the corrugation processing direction a plurality of times. Further, each time the corrugation is performed, the corrugation pattern processed by the corrugation can be adjusted by switching to the other pair of the corrugated gears by the gear switching means. Therefore, multidirectional corrugated materials with various corrugated shapes can be manufactured.

Further, for example, when switching to another corrugated gear by the gear switching means during one continuous corrugating process, even if it is a single continuous thin plate material, the corrugated shape is in the continuous direction. A changing multidirectional corrugation material can be produced.

As an aspect of the present invention, the plurality of types of corrugated gears are arranged coaxially with a pair of corrugated gears, and the gear switching means is constituted by a gear slide means for sliding the pair of corrugated gears in the axial direction. It can be.

It can be measured.

However, each of the plurality of types of corrugated gears is bent in a convex direction with respect to one of the corrugated gears by outputting each detected rotational torque in the rotational driving means that rotationally drives each of the plurality of corrugated gears Not only the waveform but also the portion bent by the other corrugated gear, that is, the shape of the waveform bent in the concave direction with respect to the one corrugated gear can be measured.

Show.

The axial sliding corrugated material manufacturing apparatus 1 includes a corrugated portion 10 that manufactures a corrugated corrugated material 130 (bidirectional corrugated material 100) by corrugating the aluminum sheet material 120 (the corrugated corrugated material 130). The corrugated portion 10 is composed of a corrugated shape measuring portion 20 that measures the corrugated shape of the corrugated corrugated material 130 (two-way corrugated material 100) based on the rotational torque during corrugating in the corrugated portion 10.

As shown in FIGS. 1 and 2, the corrugating unit 10 includes processing gear rollers 11 (11a, 11b) for corrugating, and servo motors 16 (16a, 16b) for rotating and driving the processing gear rollers 11, respectively. A processing gear roller slide mechanism 17 that slides the processing gear roller 11 in the axial direction (longitudinal direction X) and a box 19 that includes the processing gear roller 11, the servo motor 16, and the processing gear roller slide mechanism 17. Is provided with an inlet 19a through which an aluminum thin plate material 120 (corrugated corrugated material 130) to be corrugated is placed.
The axial direction (longitudinal direction X) described above coincides with the width direction W described later, and the corrugating direction L is orthogonal to the axial direction (longitudinal direction X).

The processing gear roller 11 has a gear tooth 11c in a direction orthogonal to the corrugating direction L (FIG. 3) according to the corrugated shape applied to the aluminum sheet material 120 or the like, and has a width of the aluminum sheet material 120 or the like. The upper processing gear roller 11a is formed so as to be about three times as long as the gear teeth 11c mesh with each other with a clearance K (FIG. 7) corresponding to the thickness of the aluminum sheet 120 to be corrugated. And the lower processing gear roller 11b.

Specifically, the narrow gap gear portion 14, the standard gap gear portion 12, and the wide gap gear portion 13 that are each slightly longer than the width of the aluminum sheet 120 are arranged concentrically in this order in the longitudinal direction X. The narrow gap gear portion 14, the standard gap gear portion 12, and the wide gap gear portion 13 are formed so that their diameters are gradually reduced in this order, and gear teeth 11c having the same shape are provided on the outer peripheral surface.

Further, the processing gear roller 11 is formed to be about five times as long as the width of the aluminum thin plate material 120, and is supported so as to be slidable in the longitudinal direction X with respect to the rotation support shaft 15 connected to the servo motor 16. Has been.

As an example, the gear teeth 11c of the processing gear roller 11 of the present embodiment in which the corrugated shape is applied to the aluminum sheet material 120 of about 0.04 mm, the height of the gear teeth 11c is about 0.5 mm, the apex angle is about 32 degrees, The pitch is about 1 mm and R is about 0.25 mm.

The upper processing gear roller 11a and the lower processing gear roller 11b of the processing gear roller 11 configured in this way correspond to the thickness of the aluminum sheet 120 or the like on which the convex portions and concave portions of the gear teeth 11c are subjected to corrugation. It arrange | positions so that the clearance K may be spaced apart. As a result, the clearance K in the standard interval gear portion 12 of the processing gear roller 11 is the standard interval H, the clearance K in the wide interval gear portion 13 is the wide interval H1, and the clearance K in the narrow interval gear portion 14 is the narrow interval H2.

As shown in FIG. 7A, the standard interval H is the clearance K between the upper processing gear roller 11a and the lower processing gear roller 11b, and the thickness of the aluminum sheet 120 and the height of the gear teeth 11c of the processing gear roller 11. It is the interval set according to. The wide interval H1 is an interval larger than the standard interval H, and is an interval in which the aluminum thin plate member 120 is interposed between the gear teeth 11c of the processing gear roller 11. The narrow interval H2 is an interval narrower than the standard interval H, and is slightly larger than the thickness of the aluminum sheet 120.

As an example, the axially sliding corrugated material manufacturing apparatus 1 of this embodiment that applies a corrugated shape to an aluminum thin plate material 120 having a thickness of about 0.04 mm has a standard interval H of about 0.32 mm and a wide interval H1 of about 0. .45 mm and the narrow interval H2 is about 0.28 mm.

The servo motor 16 is a servo motor that independently drives the pair of machining gear rollers 11 to rotate. The upper servo motor 16a that rotationally drives the upper machining gear roller 11a and the lower servo motor that rotates the lower machining gear roller 11b. The servo motor 16b is connected to a control device 21 in the finished shape measuring unit 20 described later.

For this reason, the upper servomotor 16a and the lower servomotor 16b that independently rotate the processing gear roller 11 rotate so that the rotation of the upper processing gear roller 11a and the lower processing gear roller 11b is synchronized. The rotation is controlled by the control device 21 of the unit 20.

As described above, the processing gear roller slide mechanism 17 is a mechanism that slides the processing gear roller 11 supported to be slidable in the longitudinal direction X with respect to the rotation support shaft 15 in the longitudinal direction X. The control device 21 controls the slide position of the processing gear roller 11.

Specifically, when corrugating is performed with the standard interval gear portion 12 with the clearance K being the standard interval H, the standard interval gear portion 12 is located at the center position of the rotation support shaft 15 that is the front face of the insertion port 19a. The processing gear roller 11 is slid by the processing gear roller slide mechanism 17. Further, when corrugating is performed with the wide gap gear portion 13 having the clearance K of the wide gap H1, the machining gear roller 11 is moved so that the wide gap gear portion 13 is at the center position of the rotation support shaft 15 as shown in FIG. When the corrugation processing is performed by the narrow gear portion 14 having the clearance K having the narrow interval H2, the narrow gear portion 14 is rotated by the rotation support shaft 15 as shown in FIG. The processing gear roller 11 is slid by the processing gear roller slide mechanism 17 so as to be in the center position.

The finished shape measuring unit 20 includes a control device 21, a display device 22, a storage device 23, a torque detection sensor 24, an operation device that is an input device such as a mouse and a keyboard, and a storage medium reading device that reads various storage media such as a DVD-RAM. Or a storage medium read / write device and a transmission / reception device configured by a communication device such as a LAN board connectable to a network.

The control device 21 includes a CPU, a ROM, and a RAM, and executes various control processes according to a program stored in the storage device 23.
The display device 22 is a device configured by a liquid crystal monitor, a CRT display, or the like to display various information.

The storage device 23 is composed of a hard disk or the like, and includes various data including detected rotational torque data detected by the torque detection sensor 24 and reference rotational torque temporal change data BL (see FIGS. 17A and 18A). In addition, various programs including a temporal change data calculation program for calculating temporal change data of the detected rotational torque and a control program or a determination program for controlling various devices are stored.

The torque detection sensor 24 (24a, 24b) is a sensor that is connected to the control device 21 and detects the rotational torque of the servo motor 16 during corrugating, and is connected to the control device 21. The upper torque detection sensor 24a is connected to the upper servomotor 16a, and the lower torque detection sensor 24b is connected to the lower servomotor 16b to detect the respective rotational torques and detect detected rotational torque data. Is transmitted to the control device 21. In addition, the rotation angle of the servo motor 12 is detected by an encoder (not shown), and the rotation torque detected by the torque detection sensor 24 and the rotation angle are associated with each other and transmitted to the control device 21.

Then, the manufacturing method of the two-way corrugated material 100 using the axial direction slide-type corrugated material manufacturing apparatus 1 having such a configuration and the measurement of the corrugated shape will be described.
Briefly, as shown in FIG. 3, the two-way corrugated material 100 performs the first corrugating process on the aluminum sheet material 120 to produce the corrugated corrugated material 130. As shown in FIG. 4, it is manufactured by applying a second corrugating process. The measurement of the corrugated shape is performed based on the detected rotational torque of the servomotor 16 during each corrugation process.

The corrugated shape of the corrugated corrugated material 130 applied by the processing gear roller 11 is an upward convex shape and a downward convex shape corresponding to the shape of the gear teeth 11c of the processing gear roller 11 (12, 13, 14), as shown in FIG. The shape is a waveform shape that is alternately continuous in the corrugating direction L, but the processing gear roller 11 is slid by the processing gear roller slide mechanism 17 so that the clearance K has different standard interval gear portion 12, wide interval gear portion 13 and narrow Various corrugated shapes can be formed on the two-way corrugated material 100 manufactured by the above-described manufacturing method by corrugating with one of the spacing gear portions 14.

Specifically, the corrugation is performed by any one of the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14 having different clearances K during the first corrugation processing for processing the corrugated corrugated material 130 from the aluminum sheet material 120. Or whether the corrugation is performed by any one of the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14 having different clearances K in the second corrugation processing for processing the bi-directional corrugated material 100 from the corrugated corrugated material 130 By selecting this, it is possible to form corrugated shapes of various patterns shown in FIGS. 8 and 10 to 15.

A description will be given of the first pattern bi-directional corrugated material 100a in the case of processing with the standard interval gear portion 12 with the clearance K being the standard interval H in both the first corrugation processing and the second corrugation processing.

The corrugated bi-directional corrugated material 100 having various patterns shown in FIGS. 8 and 10 to 15 has a width direction W (lower right to upper left in the drawing) as a processing direction at the time of the first corrugating process. The processing direction at the time of the second corrugating process orthogonal to the processing direction at the time of the first corrugating process is defined as the depth direction V (lower left to upper right in the figure), and further the thickness direction D of the two-way corrugated material 100 is illustrated in the figure. It is shown in the vertical direction.

As shown in the cross-sectional view of FIG. 9A, the first pattern bi-directional corrugated material 100a has a wavy shape having ridges 101 that protrude in a mountain shape when seen from the side in the width direction W at regular intervals. The raised portion 101 has a narrow first convex portion 102 and a narrower first concave portion 103 in the width direction W repeatedly (see FIG. 9B). On the other hand, in the low part between the said protruding parts 101, it is the shape which repeats the wide 2nd convex part 107 and the narrower 2nd recessed part 108 in the width direction W (refer FIG.9 (c)).

The first convex portion 102 has a shape in which the top surface 104 is slightly curved downward and both sides 105 are inverted, and the first concave portion 103 has a flat bottom portion 106. On the other hand, the second convex portion 107 has a flat top surface 109, and the second concave portion 108 has a shape in which the bottom surface 110 is slightly curved upward and both sides 111 have a square shape. The raised portion 101, the first convex portion 102, the first concave portion 103, the second convex portion 107, and the second concave portion 108 constitute a corrugated shape of the first pattern bi-directional corrugated material 100a.

This is because the waveform of the corrugated corrugated material 130 formed by the standard interval gear portion 12 with the clearance K being the standard interval H at the time of the first corrugation is the standard interval at which the clearance K is the standard interval H at the time of the second corrugation. When the upper processing gear roller 11a and the lower processing gear roller 11b corrugated by the gear portion 12 are crushed when forming a waveform, the top surface 104 is slightly curved downward, and both sides 105 are formed in a reverse letter C shape. A corrugated shape having a certain first protrusion 102 is formed.

As described above, the first pattern bi-directional corrugated material 100a formed when corrugated with the standard interval gear portion 12 with the clearance K being the standard interval H in both the first corrugating process and the second corrugating process. When corrugating is performed by the wide gap gear portion 13 having the clearance K of the wide gap H1 during both the first corrugating process and the second corrugating process, the second pattern bi-directional corrugated material 100b shown in FIG. 10 can be formed.

The second pattern two-way corrugated material 100b has a waveform having a low height of the corrugated corrugated material 130 formed by the wide interval gear portion 13 having a clearance K having a wide interval H1 during the first corrugation process. When the wide gap gear portion 13 having the clearance K of the wide gap H1 is crushed when forming a low waveform, the substantially dome-shaped convex portions 116a and concave portions 116b are alternately arranged in a lattice shape in plan view. A corrugated shape, that is, a corrugated shape arranged in a sine wave shape in the width direction W and the depth direction V is obtained.

The low-profile waveform formed by the wide-gap gear portion 13 with the clearance K having the wide interval H1 is higher than the waveform formed by the standard-distance gear portion 12 with the clearance K having the standard interval H. It shows that the waveform is low.

When corrugating is performed with the wide-interval gear portion 13 with the clearance K being the wide interval H1 during the first corrugating, and corrugating is being performed with the narrow-interval gear portion 14 with the clearance K being the narrow interval H2 during the second corrugating operation The 3rd pattern bi-directional corrugated material 100c shown in FIG. 11 can be formed.

The third pattern bi-directional corrugated material 100c crushes the low corrugation of the corrugated corrugated material 130 formed by the wide gap gear portion 13 having a clearance K having a wide gap H1 during the first corrugation process. At the time of processing, since the narrow gap gear portion 14 with the clearance K being the narrow gap H2 forms a high waveform, the high transverse wave 113 having the concave portions 113a spaced at a predetermined interval on the top is predetermined in the depth direction V. The corrugated shape is arranged at intervals.

The high waveform formed by the narrow gap gear portion 14 with the clearance K being the narrow interval H2 is higher than the waveform formed by the standard interval gear portion 12 having the clearance K being the standard interval H. It shows a high waveform.

Further, when corrugating is performed with the wide interval gear portion 13 having the clearance K at the first corrugation processing with the wide interval H1, and corrugating processing is performed with the standard interval gear portion 12 with the clearance K at the second corrugation processing being the standard interval H. The third pattern bi-directional corrugated material 100c having the same shape can be formed although the height of the transverse wave 113 is reduced.

The third pattern bi-directional corrugated material 100c is corrugated by the narrow gap gear portion 14 having a clearance K of a narrow interval H2 in the first corrugating process, and the clearance K in the second corrugating process is a wide gap H1 having a wide interval H1. When corrugation processing is performed by the spacing gear portion 13, a fourth pattern bi-directional corrugated material 100d shown in FIG. 16 can be formed.

The fourth pattern bi-directional corrugated material 100d is a second corrugated corrugated top portion of the corrugated material 130 formed by the narrow gap gear portion 14 having a clearance K of a narrow gap H2 during the first corrugation process. At the time of processing, the wide gap gear portion 13 with the clearance K having a wide gap H1 is crushed into a wave shape with a low height, so that a high vertical wave 114 having a concave portion 114a with a predetermined gap at the top is formed in the width direction W. The corrugated shape is arranged at predetermined intervals.

In addition, when corrugating is performed with the standard interval gear portion 12 with the clearance K being the standard interval H during the first corrugation, and corrugating is performed with the wide interval gear portion 13 with the clearance K being the wide interval H1 during the second corrugation processing. In this case, the fourth pattern bi-directional corrugated material 100d having the same shape can be formed although the height of the longitudinal wave 114 is reduced.

Further, in the first corrugating process and the second corrugating process, with respect to the first pattern two-way corrugated material 100a when the corrugating process is performed with the standard interval gear portion 12 having the clearance K of the standard interval H, the first corrugating process and When corrugation is performed by the narrow gap gear portion 14 having a clearance K of the narrow gap H2 during the second corrugation, as shown in FIG. 13, the width direction W and depth are larger than those of the first pattern bi-directional corrugated material 100a. A fifth pattern bi-directional corrugated material 100e having a corrugated shape having a large direction V and thickness direction D can be formed.

Furthermore, when corrugating is performed with the narrow gap gear portion 14 having the clearance K at the first interval of the first corrugation, and corrugating is performed with the standard interval gear portion 12 having the clearance K of the second corrugation, which is the standard interval H. As shown in FIG. 14, the sixth pattern bi-directional corrugated material having a corrugated shape in which the depth direction V is the same as that of the first pattern bi-directional corrugated material 100a but the width direction W and the thickness direction D are large. 100f can be formed.

On the contrary, the corrugation is performed with the standard interval gear portion 12 having the clearance K at the first corrugation processing with the standard interval H, and the corrugation is processed with the narrow interval gear portion 14 with the clearance K being the narrow interval H2 at the second corrugation processing. In this case, as shown in FIG. 15, the seventh pattern bi-directional corrugate having a corrugated shape in which the width direction W is the same as that of the first pattern bi-directional corrugated material 100 a but the depth direction V and the thickness direction D are large. 100 g of material can be formed.

Thus, in the corrugating part 10 of the axial direction sliding corrugated material manufacturing apparatus 1, the clearance K between the upper processing gear roller 11a and the lower processing gear roller 11b is made of aluminum during the first corrugating process and the second corrugating process. The corrugation is performed by any one of the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14 so that the standard interval H, the wide interval H1, and the narrow interval H2 according to the thickness of the thin plate material 120 are obtained. By selecting by sliding with the roller slide mechanism 17, various corrugated bi-directional corrugated materials 100 can be configured as shown in Table 1 below.

In addition, the bi-directional corrugated material 100 configured as described above has improved workability according to the corrugated shape, in particular, an LDR (Limiting Drawing Ratio) or a limiting drawing ratio is high, drawing property is good, and complicated. Even fine processing is possible.

Furthermore, since the airflow flowing along the surface of the two-way corrugated material 100 can be adjusted according to the corrugated shape of the two-way corrugated material 100 and the depth in the thickness direction D, as described above, By adjusting the clearance K, the two-way corrugated material 100 having a desired heat shielding effect can be manufactured.

Furthermore, since the reflection action by electromagnetic waves on the surface of the two-way corrugated material 100 can be adjusted according to the corrugated shape of the two-way corrugated material 100 and the depth in the thickness direction D, as described above, By adjusting the clearance K, the two-way corrugated material 100 having a desired shielding effect can be manufactured.
In the above description, the two-way corrugated material 100 is composed of the aluminum thin plate material 120, but may be composed of a paper plate or a resin plate.

Subsequently, in the manufacturing process of the two-way corrugated material 100 in the axial sliding corrugated material manufacturing apparatus 1 as described above, the measurement of the corrugated shape using the measured shape measuring unit 20 will be described with reference to FIGS. 16 to 18. .
16 shows a manufacturing flow chart of the bi-directional corrugated material 100, FIG. 17 shows an explanatory diagram of the measurement result of the first corrugation, and FIG. 18 explains the measurement result of the second corrugation. The figure is shown.

Specifically, FIGS. 17 (a) and 18 (a) show graphs of measurement results of each corrugation, and FIG. 17 (b) shows a result of the corrugated corrugated material 130 from the perspective direction in the first corrugation. An image is shown and FIG.18 (b) has shown the completed image from the perspective direction of the two-way corrugated material 100 in a 2nd corrugation process.

In manufacturing the bi-directional corrugated material 100, the temporal change data of the rotational torque when a predetermined corrugated shape is processed is stored in the storage device 23 as the reference rotational torque temporal change data BL that is a reference for pass / fail judgment (step s1). .

At this time, the storage device 23 stores reference rotational torque temporal change data (comparison reference information BL1, BL2) in the first corrugating process and the second corrugating process corresponding to the standard interval H, the wide interval H1, and the narrow interval H2. To do.

The reference rotational torque temporal change data BL in step s1 is not stored every time the bi-directional corrugated material 100 is manufactured, and the reference rotational torque temporal change data BL already stored in the storage device 23 is called. Good. In addition, a plurality of reference rotational torque temporal change data BL is stored in the storage device 23 in accordance with the corrugated shape, the number of corrugating processes, or the material strength and thickness of the aluminum sheet 120, and is selected before processing. May be.

After step s1 is completed, in order to manufacture the bi-directional corrugated material 100 having a desired corrugated shape, the clearance K at the time of the first corrugating process corresponding to the corrugated shape is suitable among the standard interval H, the wide interval H1, and the narrow interval H2. The machining gear roller slide mechanism 17 is controlled and driven so that the gap gear portion is located at the center position of the rotation support shaft 15 (step s2).

After the machining gear roller 11 is completely slid by the machining gear roller slide mechanism 17, the aluminum sheet material 120 is introduced from the inlet 19 a (FIG. 2) of the corrugating part 10, and the first corrugation process is performed on the aluminum sheet material 120. In addition, the rotational torque of the servo motor 16 at the time of the first corrugating process is detected by the torque detection sensor 24 of the finished shape measuring unit 20 and stored in the storage device 23 (step s3).

Specifically, as shown in FIG. 3, the aluminum sheet material 120 introduced from the insertion port 19 a passes between the upper processing gear roller 11 a and the lower processing gear roller 11 b, thereby forming the gear teeth 11 c of the processing gear roller 11. It is carried out from the back side of the box 19 as a corrugated corrugated material 130 that has been bent according to its shape.

The control device 21 that has received the rotational torque of the servo motor 16 at the time of the first corrugating process detected by the torque detection sensor 24 in step s3 as the detected rotational torque is obtained by the temporal change data calculation program stored in the storage device 23. Calculation of the detected rotational torque is performed, and the graph is displayed on the display device 22 as shown in FIG. 17 (step s4).

As shown in FIG. 17 (a), the calculated temporal change data includes both the upper servomotor 16a that rotationally drives the upper processing gear roller 11a and the lower servomotor 16b that rotationally drives the lower processing gear roller 11b. The graph is displayed as the time-dependent change data of the detected rotational torque. The upward convex portion of the calculated temporal change data in the upper servomotor 16a indicates the corrugated shape on the upper surface side of the corrugated corrugated material 130, and conversely, the downward convex portion of the calculated temporal change data in the lower servomotor 16b. Shows the corrugated shape on the lower surface side of the corrugated corrugated material 130.

As a result, when the corrugated corrugated material 130 shown in FIG. 17B is not formed with a sufficient corrugated side as in the front side in the corrugating direction L, as shown on the left side of FIG. It can be seen that the detected torque is smaller than the temporal change data in the determination.

The control device 21 compares the calculated temporal change data with the first corrugating reference rotational torque temporal change data BL1 stored in the storage device 23 (step s5), and makes a pass / fail determination by the determination program. At this time, when the calculated temporal change data exceeds the range of the first corrugating reference rotational torque temporal change data BL1 (step s6: No, including the defect determination area shown in FIG. 15A), this wavy The corrugated material 130 is determined to be unacceptable (step s16), and the process ends. Conversely, when the calculated temporal change data is within the range of the first corrugation reference rotational torque temporal change data BL1 (step s6: Yes, only in the good judgment region shown in FIG. 15A), this corrugated corrugated material 130 is determined to be acceptable.

And in order to perform a 2nd corrugation process with respect to the corrugated corrugated material 130 determined to pass at step s6, the clearance K at the time of the 2nd corrugation process according to the corrugate shape to manufacture is the standard space | interval H and the wide space | interval H1. Then, the processing gear roller 11 is slid by controlling the processing gear roller slide mechanism 17 so that the gear portion having an appropriate interval in the narrow interval H2 is at the center position of the rotation support shaft 15 (step s7).

After the processing gear roller 11 is completely slid by the processing gear roller slide mechanism 17, the direction in which the continuous direction of the waveform formed by the first corrugating process is orthogonal to the corrugating process direction L as shown in FIG. Then, the corrugated corrugated material 130 is introduced from the introduction port 19a.

As shown in FIG. 4, the corrugated corrugated material 130 introduced from the introduction port 19 a passes between the upper machining gear roller 11 a and the lower machining gear roller 11 b, and thus corresponds to the shape of the gear teeth 11 c of the machining gear roller 11. The bi-directional corrugated material 100 that has been subjected to bending is carried out from the back side of the box 19.

In addition, the rotational torque of the servo motor 16 at the time of the second corrugating process is detected by the torque detection sensor 24 of the finished shape measuring unit 20 and stored in the storage device 23 (step s8). The control device 21 that has received the rotational torque of the servo motor 16 at the time of the second corrugating process detected by the torque detection sensor 24 in step s8 as the detected rotational torque is detected by the time-dependent change data calculation program stored in the storage device 23. Torque calculation time-varying data is calculated and displayed on the display device 22 as a graph as shown in FIG. 18 (step s9).

As shown in FIG. 18 (a), the calculated temporal change data is similar to the calculated temporal change data at the time of the first corrugating process. The lower convex portion of the calculated time-dependent change data in the lower servo motor 16b shows the corrugated shape on the lower surface side of the two-way corrugated material 100. That is, the two-way corrugation shown in FIG. 9A is obtained by combining the upward convex portion of the calculated temporal change data in the upper servomotor 16a and the downward convex portion of the calculated temporal change data in the lower servomotor 16b. The corrugated shape of the two-way corrugated material 100 shown in the end view of the AA cut portion of the material 100 is shown.

As a result, when the desired corrugated material is formed on the entire bi-directional corrugated material 100 shown in FIG. 18B, the entire time-dependent change data may be obtained as shown in FIG. 18A. I understand.

The control device 21 compares the calculated temporal change data with the second corrugating reference rotational torque temporal change data BL2 stored in the storage device 23 (step s10), and makes a pass / fail determination by the determination program. At this time, when the calculated temporal change data exceeds the range of the second corrugation reference rotational torque temporal change data BL2 (step s11: No), the two-way corrugated material 100 is determined to be rejected (step s16). . Conversely, when the calculated temporal change data is within the range of the second corrugating reference rotational torque temporal change data BL2 (step s11: Yes, only the good judgment region shown in FIG. 16A), these two directions The corrugated material 100 is determined to be acceptable.

As described above, in order to manufacture the bi-directional corrugated material 100, the processing gear roller 11 that sandwiches the aluminum thin plate material 120 and corrugates it, the standard interval gear portion 12, the wide interval gear portion 13, and Servo motor 16 that includes narrow gap gear portion 14 and rotationally drives machining gear roller 11, and machining gear roller slide that switches standard gap gear portion 12, wide gap gear portion 13, and narrow gap gear portion 14 in machining gear roller 11. The corrugating direction in the first corrugating process with respect to the corrugated corrugated material 130 that is sandwiched between the processing gear rollers 11 and corrugated into the aluminum sheet 120 using the axially sliding corrugated material manufacturing apparatus 1 having the mechanism 17. Corrugation in the direction intersecting In addition, the corrugated material can be switched between the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14 by the processing gear roller slide mechanism 17, so that various corrugated bi-directional corrugated materials are provided. 100 can be manufactured.

Specifically, the processing gear roller 11 that corrugates by sandwiching the aluminum sheet material 120 includes the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14 having different diameters of the gear body, and the processing gear roller 11 Using the axially slidable corrugated material manufacturing apparatus 1 provided with a servo motor 16 that rotates and a processing gear roller slide mechanism 17 that switches between the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14, respectively. Two-way corrugation is performed by applying a second corrugating process in a direction intersecting the corrugating process direction to the corrugated corrugated material 130 sandwiched between the processing gear rollers 11 and corrugated into the aluminum sheet 120. The material 100 can be manufactured.

In addition, the corrugation pattern processed by corrugation can be adjusted by enabling the processing gear roller slide mechanism 17 to switch to another processing gear roller 11 for each corrugation processing. Therefore, various corrugated two-way corrugated materials 100 can be manufactured.

Further, the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14 are arranged on the same axis of the processing gear roller 11, and the standard interval gear portion 12 and the wide interval gear portion 13 are arranged by the processing gear roller slide mechanism 17. And the narrow gap gear part 14 can be switched by sliding in the longitudinal direction X with a simple structure, and the bi-directional corrugated material 100 having a plurality of types of corrugated shapes can be manufactured.

Further, the axial slide type corrugated material manufacturing apparatus 1 performs corrugation processing on the aluminum sheet material 120 sandwiched between the torque detection sensor 24 that detects the detected rotational torque of each servo motor 16 as the detected rotational torque and the processing gear roller 11. And a display device 22 for outputting the detected rotational torque at the time, and measuring the waveform shape by corrugation based on the change over time of the detected rotational torque output by the display device 22, thereby providing a standard interval in the processing gear roller 11. Measuring the overall shape of the corrugated shape of the bi-directional corrugated material 100 formed by corrugating with the aluminum sheet 120 sandwiched between the gear portion 12, the wide gear portion 13 and the narrow gear portion 14 while corrugating. Can do.
More specifically, the aluminum sheet material 120 is used in corrugating by detecting the rotational torque of the servo motor 16 that rotationally drives the processing gear roller 11 that sandwiches the aluminum sheet material 120 and corrugating it as the detected rotational torque. The load when bending can be detected.

If the plate thickness of the aluminum thin plate material 120 or the corrugated corrugated material 130 is constant and the shape of the gear teeth 11c and the diameter of the gear body are the same, the rotational torque varies depending on the bending angle in V-bending. Under a constant plate thickness, when the bending angle in V bending is large, the rotational torque increases. Conversely, when the bending angle in V bending is small, the rotational torque decreases.

For this reason, the corrugated aluminum sheet material 120 and the corrugated corrugated material are obtained by grasping the change over time of the detected rotational torque in which the bending angle increases when the rotational torque is high and the bending angle decreases when the rotational torque is low. It is possible to measure the overall shape of 130 corrugated shapes.

Further, among the processing gear rollers 11 having the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14, the aluminum thin plate material 120 is a convex portion of the gear teeth 11c of the upper processing gear roller 11a (lower processing gear roller 11b). In the concave portion, the aluminum sheet material 120 bent by the convex portion of the gear teeth 11c of the lower processing gear roller 11b (upper processing gear roller 11a) is received.

Therefore, a portion bent by the machining gear roller 11 from the detected rotational torque in the servo motor 16 that rotationally drives the machining gear roller 11 having the standard gap gear portion 12, the wide gap gear portion 13, and the narrow gap gear portion 14, that is, Only the waveform bent in the convex direction with respect to the processing gear roller 11 can be measured.

However, by outputting the respective detected rotational torques in the servo motor 16 that is rotationally driven with respect to both the processing gear roller 11 having the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14, the upper side Not only the waveform bent in the convex direction with respect to the processing gear roller 11a (lower processing gear roller 11b), but also the portion bent by the lower processing gear roller 11b (upper processing gear roller 11a), that is, the upper processing gear roller 11a (lower side). The shape of the waveform bent in the concave direction with respect to the processing gear roller 11b) can also be measured.

Therefore, it is possible to measure the corrugated shape of the entire corrugated shape corrugated in both directions with respect to the surface of the aluminum sheet material 120, and measure the entire corrugated shape formed simultaneously with the corrugated processing. Can be completed. Therefore, the two-way corrugated material 100 in which an inappropriate corrugate is formed can be discovered early.

In addition, although the above-mentioned axial direction slide type corrugated material manufacturing apparatus 1 was an apparatus in which the corrugated portion 10 and the finished shape measuring portion 20 were integrated, the corrugated portion 10 and the finished shape measuring portion 20 were independent. A configuration may be sufficient and the shape measurement part 20 may be mounted with respect to the existing corrugating part 10.

Further, in the above description, the corrugating process is performed twice on the aluminum sheet material 120. However, the corrugated corrugated material 130 obtained by performing the corrugating process once on the aluminum sheet material 120 may be used as a product. And you may give corrugation processing 3 times or more. Furthermore, the machining direction of the multiple corrugating operations may be not only the direction orthogonal to the immediately preceding corrugating machining direction, but also the direction intersecting at other angles. Corrugating may be applied in the same direction.

Further, the processing gear roller 11 is slid by the processing gear roller slide mechanism 17 to switch the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14, and the clearance K is set as a desired interval during the first corrugation processing and Although the second corrugating process was performed, the processing gear roller slide mechanism 17 is controlled and driven in the middle of the first corrugating process and the second corrugating process, and the standard interval gear part 12, the wide interval gear part 13, and the narrow interval gear are driven. The interval of the clearance K may be set as a desired interval by switching the part 14.

In this way, during the corrugating process, by switching the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14 to set the clearance K to a desired interval, the width direction W and depth of the two-way corrugated material 100 are changed. A two-way corrugated material 100 whose corrugated shape changes midway in the direction V can be manufactured. Accordingly, when the corrugated bi-directional corrugated material 100 is three-dimensionally deformed, a corrugated shape capable of exhibiting desired performance for each part can be set, and a corrugated material having a desired shape can be manufactured.

In the above description, the machining gear roller 11 is slid by the machining gear roller slide mechanism 17 to switch the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14 so that the clearance K becomes a desired interval. The corrugation processing is performed, but the processing gear roller slide mechanism 17 slides the insertion port 19a without sliding the processing gear roller 11, and the aluminum thin plate material 120 introduced from the insertion port 19a has a desired interval. Corrugating may be performed in any one of the portion 12, the wide gap gear portion 13, and the narrow gap gear portion 14.

Further, the standard interval gear portion 12, the wide interval gear portion 13 and the narrow interval gear portion 14 in the processing gear roller 11 use the same gear teeth 11c to make the diameter of the gear body of the processing gear roller 11 different so that the clearance K is standardized. Although the interval H, the wide interval H1, and the narrow interval H2 are used, in the processing gear roller 11 having the same diameter, the gear teeth 11c having different gear tooth heights are used, and the standard interval gear portion 12, the wide interval gear portion 13, and the like. The narrow gap gear portion 14 may be configured.

Further, the processing gear roller 11 is supported by the rotation support shaft 15 connected to the servo motor 16 and formed to have a length about five times that of the aluminum thin plate material 120. The standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14 are switched by sliding with the roller slide mechanism 17, but the rotation support shaft 15 is formed to have the same length as the processing gear roller 11 and processed. The gear roller 11 and the servo motor 16 may be slid by the machining gear roller slide mechanism 17 to switch the standard interval gear portion 12, the wide interval gear portion 13, and the narrow interval gear portion 14.

Subsequently, a case where the two-way corrugated material 100 is manufactured using the rotary corrugated material manufacturing apparatus 4 having a clearance K of a desired interval without sliding the processed gear roller 11 by the processed gear roller slide mechanism 17 is shown in FIG. It demonstrates with thru | or FIG.

FIG. 23 shows an explanatory diagram of rotation switching of the processing gear roller.

Specifically, FIG. 19 shows a partially enlarged schematic view of the corrugated portion 40 in the rotary corrugated material manufacturing apparatus 4.
FIG. 21A shows a schematic view of a state in which corrugation is performed by the standard interval gear portion 12a of the processing gear roller 11, and FIG. 21B shows a state after corrugation processing by the standard interval gear portion 12a of the processing gear roller 11 is performed. FIG. 21 (c) shows a schematic diagram of a state in which the machining gear roller 11 is moved up and down, and FIG. 21 (c) shows a schematic diagram of a state in which the machining gear roller 11 is reversely rotated for corrugating again at the standard interval gear portion 12a of the machining gear roller 11 moved up and down. 22 (a) is a schematic diagram showing a state in which the standard interval gear portion 12a of the reversely rotated processing gear roller 11 is moved up and down to corrugate again, and FIG. 22 (b) is a diagram of the standard interval gear portion 12a of the processing gear roller 11. FIG. 22 (c) shows a schematic view of the state of corrugating again, and FIG. 22 (c) shows a state after corrugating at the standard interval gear portion 12a of the processing gear roller 11. It shows a schematic view of a state in which vertically moving the Engineering Giarora 11.

The left figure of Fig.23 (a) shows the schematic about the switching rotation for switching from the standard gap gear part 12a to the narrow gap gear part 14a, and the right figure of Fig.23 (a) shows the switched narrow gap gear part 14a. FIG. 23B shows a schematic diagram of the state of corrugating, and the left diagram of FIG. 23B shows a schematic diagram of switching rotation for switching from the narrow gap gear portion 14a to the wide gap gear portion 13a, and FIG. The right figure has shown the schematic of the state which corrugates by the switched wide space | interval gear part 13a.

In the machining gear roller 11 of the above-described axially sliding corrugated material manufacturing apparatus 1, the narrow gap gear portion 14, the standard gap gear portion 12 and the wide gap gear portion 13 having different gear main body diameters are arranged in the longitudinal direction X, and the machining gear roller 11 is slid with respect to the rotation support shaft 15, and the clearance K is selected from the standard interval H, the wide interval H1, and the narrow interval H2, thereby forming a desired corrugated shape.

On the other hand, the corrugation processing unit 40 of the rotary corrugated material manufacturing apparatus 4 assigns the outer peripheral surface of the processing gear roller 11 having a length slightly longer than the width of the aluminum sheet material 120 into three equal parts, and gear teeth in each range. 11c is adjusted to obtain a standard interval gear portion 12a, a wide interval gear portion 13a, and a narrow interval gear portion 14a, and a standard interval gear portion 12a, a wide interval gear portion 13a, and an upper processing gear roller 11a and a lower processing gear roller 11b. The processing gear roller 11 is rotated so that each of the narrow gap gear portions 14a faces each other, and corrugation processing is performed by the gear portions, thereby forming various corrugated shapes.

Therefore, instead of the processing gear roller slide mechanism 17 of the corrugating unit 10, a separation servomotor 18 that moves the processing gear roller 11 and the standard interval gear unit 12 integrally in the separation direction is provided.

In addition, the gear teeth 11c of the processing gear roller 11 of the present embodiment in which the corrugated shape is applied to the thin aluminum plate material 120 of about 0.04 mm has a height of about 0.48 mm, an apex angle of about 32 degrees, and R in the standard interval gear portion 12a. The height is about 0.25 mm, the height of the wide gap gear portion 13a is about 0.14 mm, the apex angle is about 71 degrees, the radius R is about 0.25 mm, and the height of the narrow gap gear portion 14a is about 0.60 mm and the apex angle is about 21 degrees. R is about 0.25 mm.

Thereby, the clearance K between the upper processing gear roller 11a and the lower processing gear roller 11b is a standard interval H when the standard interval gear portions 12a face each other, and a wide interval H1 when the wide interval gear portions 13a face each other. And the narrow space | interval H2 is the case where the narrow space | interval gear parts 14a oppose. Note that the standard interval H, the wide interval H1, and the narrow interval H2 are intervals in the above-described axially sliding corrugated material manufacturing apparatus 1, and thus detailed description thereof is omitted.

Since the processing gear roller 11 of the corrugating section 40 is divided into three equal parts in the circumferential direction, when the processing gear roller 11 is simply rotated, the gear tooth height after corrugating at the gear section at a desired interval is obtained. Corrugation is performed with different gear parts.

Therefore, in the corrugating part 40, the processing gear roller 11 is rotated and corrugated by any one of the standard gap gear part 12a, the wide gap gear part 13a, and the narrow gap gear part 14a (see FIG. 21 (a)). )), When the range of the gear portion is ended by rotation (FIG. 21B), the upper processing gear roller 11a and the standard interval gear portion 12a are moved upward by the upper processing gear roller separation servomotor 18a, and the lower processing gear roller The processing gear roller 11 is separated from the aluminum thin plate material 120 (the corrugated corrugated material 130) by moving the lower processing gear roller 11b and the standard interval gear portion 12b downward by the separation servo motor 18b (FIG. 21). (C)).

The processing gear roller 11 separated from the aluminum sheet material 120 (the corrugated corrugated material 130) is rotated so that the upper processing gear roller 11a and the lower processing gear roller 11b face the start positions of the gear portions that have been corrugated so far. (FIG. 22 (a)), the processing gear roller 11 is moved to a predetermined position by the separation servo motor 18, that is, the clearance K is moved to a predetermined interval (FIG. 22 (b)), and the gear The corrugating process at the part is resumed (FIG. 22C).

As described above, in the corrugating section 40, the processing gear roller 11 is rotated by the servo motor 16 to perform corrugation, and when the range of the gear section is finished, the processing is performed by the separating servo motor 18 and rotating to the start position. Resume machining. That is, the processing gear roller 11 is repeatedly rotated to form a desired corrugated shape.

Next, switching to the gear portion selected according to the desired corrugated shape will be described.
In order to switch to the gear portion selected according to the desired corrugated shape, the processing gear roller 11 is separated by the separation servo motor 18 in order to repeat the corrugation processing in the range of the gear portion after the end. The processing gear roller 11 is once separated from the predetermined position where the gear teeth 11c are engaged with each other by the separating servo motor 18, and the processing gear roller 11 is rotated until the start position of the desired gear portion opposes. The machining gear roller 11 is moved by the separation servomotor 18 to a predetermined position where the meshing gears are engaged with each other and switched.

Specifically, the case of switching from the state in which the standard interval gear portion 12a is engaged to the narrow interval gear portion 14a will be described with reference to FIG.
First, in order to switch from the standard interval gear portion 12a to the narrow interval gear portion 14a, the processing gear roller 11 in a state in which the standard interval gear portion 12a is engaged is separated by the separation servo motor 18 (FIG. 23 (a) left figure). The machining gear roller 11 is rotated by the servomotor 16 until the start position of the narrow gap gear portion 14a faces. Then, after the start position of the narrow gap gear portion 14a is opposed, the processing gear roller 11 is brought close to the separation servo motor 18 to engage the gear teeth 11c of the narrow gap gear portion 14a (FIG. 23 (a) right) Figure). In this way, the standard interval gear portion 12a can be switched to the narrow interval gear portion 14a.

Next, the case of switching from the state in which the narrow gap gear portion 14a is engaged to the wide gap gear portion 13a will be described with reference to FIG.
First, in order to switch from the narrow gap gear portion 14a to the wide gap gear portion 13a, the machining gear roller 11 in a state where the narrow gap gear portion 14a is engaged is separated by the separation servo motor 18 (FIG. 23 (b) left figure). The machining gear roller 11 is rotated by the servo motor 16 until the start position of the wide gap gear portion 13a faces. Then, after the start positions of the wide gap gear portion 13a face each other, the processing gear roller 11 is brought close to the separation servomotor 18 to engage the gear teeth 11c of the wide gap gear portion 13a (FIG. 23 (b) right) Figure). In this way, the narrow gap gear portion 14a can be switched to the wide gap gear portion 13a.

In the above description, the operation of switching from the standard interval gear portion 12a to the narrow interval gear portion 14a and the narrow interval gear portion 14a to the wide interval gear portion 13a has been described. It is possible to switch to the part 13a, and even if the reverse switching pattern is used, it is possible to switch to the desired gear part by the same switching operation. Accordingly, the two-way corrugated material 100 having various corrugated shapes can be manufactured by easily switching to the gear portion having the desired clearance K.

In this manner, the standard interval gear portion 12a, the wide interval gear portion 13a, and the narrow interval gear portion 14a having the gear teeth 11c having different shapes are arranged for each corresponding circumferential angle in the processing gear roller 11, and processed by the servo motor 16. Each of the gear rollers 11 is repeatedly rotated by a predetermined angle, and the standard interval gear portion 12 and the separation servo motor 18 cooperate with each other, so that the standard interval gear portion 12a, the wide interval gear portion 13a, and the narrow interval gear portion in the processing gear roller 11 are obtained. 14a can be switched by rotating the corresponding circumferential angle with a compact structure to switch between the standard interval gear portion 12a, the wide interval gear portion 13a, and the narrow interval gear portion 14a.

In the above description, in step s5 and s9, only the corrugated corrugated material 130 (two-way corrugated material 100) is determined to be rejected, but it is determined to be rejected in comparison with the reference rotational torque temporal change data BL. The log data for identifying the part may be accumulated, or marking may be performed, and the part that has passed the other pass determination may be used as the product. Thereby, since the corrugated shape part judged to be unacceptable can be eliminated, the accuracy of the product can be improved and the loss of the product can be reduced.

In the above description, the detected rotational torque detected by the torque detection sensor 24 is stored in the storage device 23, but may be stored in the RAM of the control device 21 that temporarily stores it.

For example, the upper processing gear roller 11a is configured such that the upper processing gear roller 11a is the standard interval gear portion 12 and the lower processing gear roller 11b is the narrow interval gear portion 14. And the lower processing gear roller 11b may be corrugated by changing the facing gear portions. As described above, the corrugating process is performed by changing the gear portions facing each other between the upper processing gear roller 11a and the lower processing gear roller 11b, so that the two-way corrugated material 100 having different corrugated shapes can be formed.
