The present invention relates to a plate processing device capable of cutting a plate.

BACKGROUND ART Conventionally, in order to manufacture parts (structural members) constituting a building, a configuration is known in which a plate processing apparatus is used to process a plate using a cutting member formed into a thin plate. For example, foamed resin insulation materials with heat-insulating properties are sometimes used as structural members for walls and floors that make up a house, and plate processing equipment is used to process this insulation material into the required size. (See Patent Document 1).

JP2013-76226A

In order to construct one building, structural members of various sizes and shapes may be required depending on the parts in which they will be used. For this reason, there is a possibility that there is room for improvement in the configuration for manufacturing high-quality structural members through highly accurate processing.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a plate material processing apparatus that can process a plate material with high precision.

In order to achieve this objective, the plate processing apparatus according to claim 1 includes:
A plate material processing device capable of cutting a plate material formed to have a predetermined thickness using a cutting member formed in a thin plate shape,
an attachment part to which the cutting member is attached, which is provided on one side in the thickness direction of the plate material with respect to a plate placement part where the plate material is placed when the plate material is cut by the cutting member;
a movement mechanism that allows the cutting member to be moved in the thickness direction of the plate material via the attachment part;
The cutting member is provided on the side opposite to the side where the mounting portion is provided when the plate material placement portion is used as a reference, and is located on both sides of the portion of the cutting member in the thickness direction of the portion of the cutting member. Equipped with a displacement limiter that can limit the amount of displacement within a certain range,
The cutting member has a main body portion formed to have a substantially constant thickness, a cutting edge capable of cutting the plate material, and an inclined portion formed such that the thickness decreases from the main body portion to the cutting edge. death,
The cutting member is configured to be able to cut a plate placed in the plate placement part with the displacement limiting part positioned on both sides in the thickness direction of the main body of the cutting member;

According to the plate material processing apparatus according to claim 1, when cutting the plate material, the cutting member is attached to the attachment part on one side in the thickness direction of the plate material with respect to the plate material placement part, so that the cutting member is attached to the attachment part. Displacement of the cutting member in the thickness direction is restricted. In addition, on the opposite side in the thickness direction of the plate material to the plate material arrangement part, even if the cutting member is about to deform by more than a preset amount, a part of the cutting member will contact the displacement limiting part, so that a certain amount will be deformed. Displacements above this are restricted. That is, the amount of displacement of the cutting member is limited within a certain range on both sides in the thickness direction of the plate relative to the plate arrangement portion.

The plate processing apparatus according to claim 2 is the plate processing apparatus according to claim 1, which comprises:
a rotation mechanism for a cutting member that rotates the cutting member around a predetermined rotation center axis; and a displacement restriction section that rotates the displacement restriction section around the predetermined rotation center axis. The rotation mechanism for the cutting member, the rotation mechanism for the cutting member, and the rotation mechanism for the displacement limiting portion are controlled to It is characterized by comprising a control device that performs control to rotate the cutting member and the displacement limiting portion synchronously about the predetermined rotation center axis in a state where the displacement limiting portion is located on both sides. It is said that

According to the plate processing apparatus of the present invention , when cutting a plate, the amount of displacement of the cutting member is limited within a certain range on both sides of the plate in the thickness direction of the plate with respect to the plate placement portion. Therefore, when the cutting member cuts the plate material, it is possible to easily avoid a situation in which the cutting member is displaced or deformed by more than a certain amount due to the resistance force received from the plate material. Therefore, there is an effect that high precision in cutting using the cutting member can be maintained and it is possible to easily manufacture high-quality structural members.

Moreover, the displacement and deformation of the cutting member can be restricted by the main body of the cutting member coming into contact with the displacement limiting portion. Therefore, it is possible to easily prevent damage to the cutting member, and it is possible to easily maintain the gap width between the cutting member and the displacement limiting portion at a substantially constant amount over a long period of time.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view showing a plate processing apparatus 10 as an example. Note that FIG. 1 schematically shows the configuration of the plate processing apparatus 10 and the electrical connections between the control device 23 and each drive mechanism, and also shows the plate operating mechanism 26 with a chain line. Further, in FIG. 1, the operating directions of the parts operated by each drive mechanism are indicated by arrows for easy understanding.

The plate material processing device 10 is a device capable of cutting a plate material 13 formed to have a certain thickness (for example, 100 mm) using a cutting member 11 formed in a thin plate shape. It is configured such that one or more structural members (for example, heat insulating materials) can be manufactured from No. 13. As shown in FIG. 1, in the plate material processing apparatus 10, a plate material 13 to be processed is placed on a support base 22 attached to a frame 21 disposed on a floor surface F, and the plate material 13 is placed under the control of a control device 23. The plate material 13 is processed by controlling its relative position and orientation to the cutting member 11.

In the plate material processing apparatus 10, the cutting member 11 is cut in the thickness direction on both sides of the plate material 13 placed on the support stand 22, on one side (upper side) and on the opposite side (lower side) in the thickness direction. The movement of the cutting member 11 is restricted, so that the cutting accuracy of the cutting member 11 can be maintained at a high level. In addition, in the plate material processing apparatus 10, the cutting member 11 not only cuts from the end surface of the plate material 13 (for example, the left and right end surfaces of the plate material 13 in FIG. 1), but also from a portion away from the end surface in the thickness direction (vertical direction) After the cutting member 11 is moved to generate a cut in the plate material 13, the cutting member 11 is moved along the surface of the plate material 13 to manufacture a structural member from the plate material 13. As a result, the outline shape of each structural member is not limited to a rectangular shape, but also structural members having other shapes such as a trapezoid or a triangle can be manufactured at a high yield.

In the following, first, the basic configuration of the plate processing device 10 will be explained, and then the configuration for restricting the movement of the cutting member 11 in the thickness direction will be explained, and then the cutting member 11 will be cut from a portion away from the end surface of the plate 13. A configuration for cutting the plate material 13 by creating cuts will be described. In the following description, the state in which the cutting member 11 advances relative to the plate material 13 is assumed to be a direction that intersects (perpendicularly intersects) the thickness direction of the plate material 13 and in which the plate materials 13 are continuous as the traveling direction. will be described as a cutting process, and the posture of the cutting member 11 (combination of the position and orientation of the cutting member 11) in the cutting process will be described as a cutting posture. Further, a state in which the cutting member 11 advances in the thickness direction of the plate material 13 to generate a notch in the plate material 13 is referred to as a cutting process, and a posture of the cutting member 11 in the notching process is referred to as a cutting posture. , a portion (area) where the plate material 13 is arranged on the support stand 22 will be described as a plate material arrangement section 13a.

As shown in FIG. 1, the plate processing device 10 includes a cutting member 11, a displacement limiting member 12, a control device 23, an upper operating mechanism 24, a lower operating mechanism 25, and a plate operating mechanism 26. There is. The cutting member 11 is attached to an upper fixed member 24a that is a part of the upper operating mechanism 24, and is attached to each part along a rail provided in the vertical direction (vertical direction in FIG. 1) and horizontal direction (horizontal direction in FIG. 1). The cutting member 11 is configured to be movable relative to the plate material 13 by sliding. The plate movement mechanism 26 also includes a clamp mechanism that clamps the ends of the plate 13 (front and rear ends in the direction perpendicular to the plane of the paper in FIG. 1), a movement mechanism that moves the clamp mechanism back and forth, and a movement mechanism that controls each mechanical part. It is configured in combination with a drive motor for operation, and is configured to be able to move the plate 13 in one direction (perpendicular to the plane of the paper in FIG. 1). The movement of the cutting member 11 by the upper movement mechanism 24 and the movement of the plate 13 by the plate movement mechanism 26 are controlled by the control device 23. By controlling this control device 23, the cutting member 11 can be placed over the entire range of the plate material 13.

Further, the upper operating mechanism 24 is provided with an operating mechanism that allows the cutting member 11 to rotate more than 360 degrees around the vertical direction, and a drive motor that operates the operating mechanism. It is configured to be able to change the direction of the cutting member 11 relative to the cutting member 11. Thereby, the cutting member 11 can be oriented in any direction along the surface of the plate 13 so that the plate 13 can be cut, and the plate 13 can be cut into various shapes.

Note that the mechanism for relatively moving the cutting member 11 and the plate material 13 in the plate processing device 10 is not limited to the above, and other mechanisms may be used. The cutting member 11 may be attached to an articulated robot that can move the cutting member 11 to cut the plate material 13. The plate processing device 10 also includes a fixed roller (not shown) that restricts the displacement of the plate 13 in the vertical direction when cutting the plate 13. The configuration may also include other commonly used configurations.

The control device 23 is a device that performs various controls including control for operating the cutting member 11, the plate material 13, and the displacement limiting member 12 when processing the plate material 13. The control device 23 is configured by, for example, a personal computer, and includes a ROM as a storage device that stores processing programs (programs that control the operations of the upper operating mechanism 24, the lower operating mechanism 25, and the plate operating mechanism 26). , a RAM for temporarily storing machining data, a CPU as an arithmetic processing unit, an information input device for inputting machining data necessary for machining the plate material 13 to manufacture parts, a keyboard, a mouse, a display, etc. Prepared and configured. The displacement operation means for relatively displacing the displacement limiting member 12 and the cutting member 11 is constituted by part of the functions of the control device 23 that controls each mechanism based on a program stored in the ROM. Note that the control device 23 does not necessarily need to be configured with one personal computer, and instead of or in addition to this, a device such as a sequencer using a relay circuit may be used, or a device such as a sequencer using a relay circuit may be used. The configuration may be such that the control is shared between the two.

Next, a configuration for restricting movement of the cutting member 11 in the thickness direction will be described with reference mainly to FIGS. 2 and 3. FIG. 2 is a perspective view showing the cutting member 11 and the displacement limiting member 12 fixed to the upper fixing member 24a. Further, FIG. 3 is an explanatory diagram of the operating mechanism in which a part of the cutting member 11 enters the displacement limiting portion 12a, and FIG. 3(A) shows the operating mechanism as viewed from the thickness direction of the cutting member 11. The cutting member 11 is shown with a solid line in its cutting position and a dashed line in its cutting position, and the shape of the upper fixing member 24a and the upper surface 13U and lower surface 13L of the plate 13 (plate arrangement part 13a) are shown with thin solid lines. ing. FIG. 3(B) is a diagram showing the relative position of the displacement limiting member 12 and the lower end 31 of the cutting member 11 when viewed from the top side, and shows the cutting posture with respect to the outer shape of the lower end 31 of the cutting member 11. It is shown by a solid line, and the cutting posture is shown by a dashed line.

When the plate material 13 is cut by the cutting member 11, the upper fixing member 24a is provided on the upper side of the plate material 13 (plate material arrangement portion 13a) corresponding to one surface side in the thickness direction of the plate material 13. The upper operating mechanism 24 is configured to be able to move the cutting member 11 along the thickness direction of the plate material 13 (vertical direction in FIG. 1) via the upper fixing member 24a. Further, the upper operating mechanism 24 is configured to rotatably support the upper fixed member 24a, and the cutting member 11 is configured to be rotatable within a movable range between the cutting posture and the cutting posture. (See Figure 3(A)).

As shown in FIG. 3, the displacement limiting member 12 is provided on the lower side opposite to the side on which the upper fixing member 24a is provided when the plate material 13 (plate material arrangement portion 13a) is used as a reference. The displacement limiting member 12 is formed, for example, by cutting a metal piece, and is formed by a surface (plane) that constitutes a gap between two symmetrical members, thereby forming a gap at a constant interval (displacement limiting portion 12a). and a gap portion (guiding portion 12b) that gradually widens to one side. Note that the displacement restricting portion 12a and the guiding portion 12b do not necessarily have to be formed in a plane, and may be formed in other shapes such as including a curved portion.

The displacement limiting member 12 is attached to the lower operating mechanism 25 and is configured to be operable in synchronization with the movement of the cutting member 11 by the upper operating mechanism 24 . Specifically, the displacement limiting member 12 is capable of sliding movement in the horizontal direction (the left-right direction in FIG. It is configured to be able to rotate more than 360 degrees around the direction. The movement and rotation of the displacement limiting member 12 by the lower operating mechanism 25 are also controlled by the control device 23, and the displacement limiting member 12 corresponds to the position and orientation of the cutting member 11 below the cutting member 11. They operate synchronously so that the cutting member 11 and the rotation center axis C (see FIG. 1) coincide.

The cutting member 11 is composed of a thin metal plate, and specifically includes a main body 32 formed to have a substantially constant thickness, a cutting edge 33 capable of cutting the plate material 13, and a main body 32. It has an inclined part 34 formed so that the thickness decreases from the tip to the cutting edge 33. A fixing part 35 (see FIG. 3(A)) is provided on the upper side of the main body part 32 of the cutting member 11, and the fixing part 35 (see FIG. 3(A)) is fixed by being sandwiched between the upper fixing member 24a on both sides in the thickness direction. The upper fixing member 24a is fastened using the fixing tool 24e, and the cutting member 11 is attached to the upper fixing member 24a.

The cutting edge 33 of the cutting member 11 is formed so that it can maintain a sharp point by polishing the inclined portion 34. The cutting edge 33 includes a main cutting edge 33a that cuts the plate material 13 in a cutting posture that continues diagonally downward and progresses in the direction along the surface of the plate material 13, and a main cutting edge 33a that cuts the plate material 13 from the lower end of the main cutting edge 33a. It is constructed by combining a sub-cutting edge 33b that continues in a short length toward another direction (diagonally upward).

The main cutting edge 33a is a part that cuts the plate material 13 in the cutting process of cutting the plate material 13 in the direction along the surface of the plate material 13, and its length corresponds to the thickness of the plate material 13 to be cut. It is set. Specifically, in the cutting process, the main cutting edge 33a is located within the thickness of the plate material 13 (plate material arrangement portion 13a) at the edge portion on the advancing direction side (right side in FIG. 3) in which the cutting member 11 advances with respect to the plate material 13. ) is set to the length provided over the entire section.

The auxiliary cutting edge 33b is provided at an edge portion of the cutting member 11 on the side opposite to the direction of movement (rear side in the direction of movement) in the cutting process (cutting posture). By providing this sub-cutting edge 33b, the degree of freedom in cutting the plate material 13 is increased, and the strength of the cutting member 11 is easily ensured. When the main cutting edge 33a is further extended to form the cutting member 11 in a substantially triangular shape with an acute corner on the lower side without providing the secondary cutting edge 33b, the angle of the lower corner of the cutting member 11 becomes smaller. As a result, the lower corner portion becomes easily damaged. By providing the auxiliary cutting edge 33b, it is possible to easily set the angle of the lower corner portion of the cutting member 11 to be large, thereby making it easier to ensure the strength of the cutting member 11. It is possible to cut the plate material 13 and increase the degree of freedom in the cutting process. Note that the shapes of the main cutting edge 33a and the secondary cutting edge 33b are not limited to linear shapes, and may have other shapes, such as including curved portions or being formed in a polygonal shape.

The length of the auxiliary cutting edge 33b is such a shape (length) that the auxiliary cutting edge 33b is not provided within the thickness range of the plate material 13 (plate material arrangement portion 13a) during the cutting process (cutting posture). Thereby, the position where the cutting edge 33 is provided is limited to a necessary location, making it easier to polish the cutting edge 33, and making it easier to avoid a situation where the plate material 13 or the worker is accidentally injured due to contact with the cutting edge 33. can do. Note that the length of the sub-cutting edge 33b does not necessarily have to be such that it is not provided within the thickness range of the plate material 13 in the cutting process, and the sub-cutting edge 33b may be formed to a length that allows the sub-cutting edge 33b to fit within the thickness range. It's okay.

The displacement limiting member 12 is located on both sides in the thickness direction of the lower end portion 31 with respect to a lower portion (lower end portion 31) corresponding to a part of the cutting member 11, and keeps the amount of displacement of the lower end portion 31 in the thickness direction constant. It is configured so that it can be limited within a range. As shown in FIG. 2, the displacement limiting member 12 forms a displacement limiting portion 12a and a guide portion 12b as a gap portion into which a part of the cutting member 11 can enter, and has one side (see FIG. 2) with respect to the displacement limiting portion 12a. The guide portion 12b is positioned in a state where it gradually expands on the lower right side of the screen 2). The gap width of the displacement limiting portion 12a is slightly larger than the thickness of the main body portion 32 of the cutting member 11, and is arranged with a gap of 0.5 mm on each side, for example. The displacement restricting portion 12a is set to have a gap width that allows the lower end portion 31 of the cutting member 11 to come into contact when the resistance force of the plate material 13 generated when cutting the plate material 13 becomes greater than a certain level. For this reason, the lower end portion 31 of the cutting member 11 is restricted from displacing more than a certain amount in the thickness direction thereof, and thereby the plate material 13 can be processed with high precision.

By controlling the upper operating mechanism 24 by the control device 23, the cutting member 11 is moved from a position above the plate material 13 corresponding to a position outside the thickness range of the plate material 13 to a position above the plate material 13, which corresponds to a position outside the thickness range of the plate material 13. It is configured to be able to shift to a state arranged within the thickness range, and is configured to be able to shift to a cutting process by entering the thickness range of the plate material 13 by a certain amount or more. When transitioning to this cutting process, the lower end 31 of the cutting member 11 in the cutting process is moved relative to the gap portion as the displacement limiting part 12a, as shown in FIGS. 3(A) and 3(B). From the state located on the front side (progressing direction side) of the moving direction, it is displaced in the direction opposite to the moving direction, and enters into the gap serving as the displacement restricting portion 12a.

A mechanism for causing the lower end portion 31 of the cutting member 11 to enter the displacement limiting portion 12a is constituted by a part of the upper operating mechanism 24. Specifically, an upper fixing member 24a to which the upper side of the cutting member 11 is fixed is provided with a support shaft 24b that rotatably supports the cutting member 11. Further, a drive cable 24c that transmits a driving force for rotating the cutting member 11 about the support shaft 24b is connected to the input shaft 24d of the upper fixing member 24a. A driving force in the vertical direction is transmitted to the driving cable 24c from a driving source (not shown) such as an air cylinder, whereby the cutting member 11 rotates within a certain range, and the lower end 31 of the cutting member 11 is configured to be able to enter into the displacement limiting portion 12a. Note that the mechanism for causing the lower end portion 31 of the cutting member 11 to enter the displacement limiting portion 12a is not limited to the above, and may be configured by another mechanism. Alternatively, the cutting member 11 may be configured by a mechanism that operates the cutting member 11 by sliding movement.

Here, in the lower end portion 31 of the cutting member 11, a portion that enters the displacement limiting portion 12a includes a main body portion 32 having a constant thickness, so that when the cutting member 11 is deformed, the cutting member 11 It is preferable that the eleven main body parts 32 be configured so as to contact the displacement limiting part 12a. In this embodiment, as shown in FIG. 3(A), the lower end position of the main body part 32 of the cutting member 11 is configured to be located below the upper end of the displacement limiting part 12a in the cutting attitude. The cutting member 11 cuts the plate material 13 based on the relative positional relationship. This prevents the cutting member 11 from being deformed or damaged, compared to the case where the inclined portion 34 and the displacement limiting portion 12a contact each other to limit the displacement of the cutting member 11 when cutting the plate material 13. It can be made easier.

In addition, the position (range) of the inclined part 34 may shift due to polishing of the cutting member 11 to sharpen the cutting edge 33, or the thickness of the inclined part 34 may gradually become thinner, so the displacement of that part may be restricted. If the configuration is such that the cutting member 11 is brought into contact with the portion 12a, the function of restricting the displacement of the cutting member 11 may be degraded. In this embodiment, the main body part 32 of the cutting member 11 enters the displacement limiting part 12a, and the main body part 32, whose thickness is likely to be kept constant, comes into contact with the displacement limiting part 12a. Therefore, the width of the gap formed between the cutting member 11 and the displacement limiting portion 12a can be easily maintained constant over a long period of time.

Further, as shown in FIG. 3A, the support shaft 24b, which is the center around which the cutting member 11 rotates, is connected to the plate member 13 ( It is arranged so as to be located on the vertically upper side along the thickness direction (vertical direction in FIG. 3(A)) of the plate arrangement portion 13a). Therefore, even if the cutting member 11 is rotated when the lower end 31 of the cutting member 11 enters the displacement limiting portion 12a, the height position of the lower end 31 of the cutting member 11 in the vertical direction hardly changes. Therefore, the lower end portion 31 is slightly protruded downward with respect to the plate material 13, and the protruded lower end portion 31 is moved relative to the displacement limiting portion 12a along the lower surface 13L of the plate material 13 to be displaced. It is possible to enter the restriction portion 12a. Therefore, since the amount of vertical downward movement of the cutting member 11 can be shortened, the time for processing the plate material 13 to manufacture a structural member can be shortened, and the displacement limiting portion 12a and the lower surface 13L of the plate material 13 can be brought closer together. It is possible to facilitate the manufacturing of structural members with high accuracy by placing the structural member in a certain position.

As described above, according to the plate material processing apparatus 10, when cutting the plate material 13, the cutting member 11 acts as an attachment part on one side (upper side) in the thickness direction (vertical direction) of the plate material 13 with respect to the plate material placement part 13a. The displacement limiter 12a limits the amount of displacement on the opposite side (lower side) in the thickness direction to within a certain range. Therefore, when the cutting member 11 cuts the plate material 13, it is possible to easily avoid a situation in which the cutting member 11 is displaced or deformed by more than a certain amount due to the resistance force received from the plate material 13. Therefore, it is possible to easily maintain high precision in cutting using the cutting member 11.

Moreover, the displacement (movement) and deformation of the cutting member 11 can be restricted by the main body portion 32 of the cutting member 11 coming into contact with the displacement limiting portion 12a. Therefore, damage to the cutting member 11 can be easily prevented, and the gap width between the cutting member 11 and the displacement limiting portion 12a can be easily maintained at a substantially constant amount over a long period of time.

Further, the lower end portion 31 of the cutting member 11 is moved to the displacement limiting portion 12a by moving in a direction opposite to the traveling direction of the cutting member 11 in the cutting process (to the rear side in the traveling direction). enter in. Therefore, compared to the case where the lower end portion 31 of the cutting member 11 enters the displacement limiting portion 12a from above, the displacement limiting portion 12a is arranged at a position closer to the plate material 13 to be processed, and the cutting member 11 movement in the thickness direction can be restricted. Therefore, it is possible to easily reduce the size of the cutting member 11 and the size of the plate processing apparatus 10, thereby making it easier to reduce costs. In addition, bending stress generated in the cutting member 11 due to the force generated when the tip (lower end 31) of the cutting member 11 contacts the displacement limiting portion 12a and the resistance force of the plate 13 can be reduced by bringing the plate and the displacement limiting portion closer together. Since the cutting member 11 is arranged in a straight line, the cutting member 11 can be kept low, and deformation and damage of the cutting member 11 can be easily prevented.

Further, the edge portion of the cutting member 11 corresponding to the rear side (the left side in FIG. 3A) in the direction of movement in the cutting posture is shaped so that the cutting edge 33 is not provided within the thickness of the plate material 13. Therefore, when the lower end portion 31 of the cutting member 11 enters the displacement limiting portion 12a, it is possible to easily avoid a situation where the plate material 13 is cut by the edge portion of the cutting member 11, and it is possible to make a high-quality structural member. It can be made easier to manufacture.

Next, a configuration in which a notch is created in the plate material 13 from a portion away from the end surface of the plate material 13 and then the plate material 13 is cut will be described with reference mainly to FIG. 4. FIG. 4 is a diagram for explaining cutting of the plate material 13 in the thickness direction and an operating mechanism when switching the cutting direction.

The cutting member 11 is cut along the thickness direction of the plate material 13 from a state where it is located on one side (upper side) in the thickness direction of the plate material 13 (a state before cutting, a state shown by the solid line in FIG. 4(A)). The cutting process is configured such that cutting of the plate material 13 can be started by a cutting step that advances toward the plate material 13 side. Specifically, as shown in FIG. 4(A), the cutting member 11 is moved from the pre-cutting state to the side opposite to the side where the upper fixing member 24a is provided when the plate arrangement portion 13a (plate material 13) is used as a reference. Cut the plate material 13 until a part of the cutting edge 33 of the cutting member 11 protrudes to the side (lower side) (protruding state, reaching the lowest end of the range surrounded by the thin line in FIG. 4(A)). It is configured to be able to be displaced in the thickness direction (in the direction of the arrow in FIG. 4(A)). This movement control of the cutting member 11 is executed by controlling the upper operating mechanism 24 (see FIG. 1) by the control device 23.

Here, when the cutting member 11 moves downward from the pre-cutting state to the protruding state when viewed in the thickness direction of the cutting member 11 (viewed in the direction perpendicular to the plane of the paper in FIG. 4), The body portion 32 and the inclined portion 34 are formed in a shape such that the main body portion 32 and the inclined portion 34 are located within a movement locus range (within a range surrounded by a thick solid line) in which the cutting edge 33 moves. That is, both the main body portion 32 and the inclined portion 34 of the cutting member 11 are formed in a shape that does not have a portion outside the movement locus range. As a result, it is possible to create a cut in the plate material 13 using only the cutting edge 33 of the cutting member 11, while arranging the inclined portion 34 and the main body portion 32 within the range where the cut is formed. The cut surface can be made nearly smooth and formed with high precision. Note that the main body portion 32 and the inclined portion 34 of the cutting member 11 may be configured in other shapes as long as the outer shape falls within the movement trajectory range of the cutting edge 33 within the plate arrangement portion 13a. The main body portion 32 may have a shape in which a through hole is provided.

Further, as shown in FIG. 4A, the cutting member 11 has a main cutting edge 33a and a sub-cutting edge 33b at the tip of a protruding portion that protrudes downward from within the thickness range of the plate material 13 (protruding tip position 36). It is provided so as to be continuous on both sides of the border. Specifically, the main cutting edge 33a is located on the advancing direction side (the right side in FIG. 4A, the first direction side) in which the cutting member 11 advances relative to the plate material 13 in the cutting process of cutting the plate material 13. It is provided on the edge of the. Then, from the protruding tip position 36 corresponding to the lowest end of the main cutting edge 33a, the length continues to a part of the edge portion on the opposite side to the advancing direction (left side in FIG. 4(A), second direction side). A sub-cutting edge 33b is provided so that the cutting edge 33 is formed. Therefore, in the cutting process, the width of the cut can be gradually expanded by the main cutting edge 33a and the secondary cutting edge 33b that are continuous on both sides of the protruding tip position 36. In this case, the main cutting edge 33a and the auxiliary cutting edge 33b are both continuous in a direction inclined with respect to the advancing direction (downward direction in FIG. 4) of the cutting edge 33 in the cutting process, thereby making the cutting surface smooth. It is possible to approximate the condition and make it easier to cut.

In addition, the angle of the cutting edge 33 that is inclined with respect to the advancing direction of the cutting edge 33 (downward in FIG. 4A) in the cutting process is smaller than the angle of the main cutting edge 33a (approximately 45 degrees) of the secondary cutting edge 33b (approximately 75 degrees). degree) is set larger. For this reason, the main body part 32 on the side where the secondary cutting edge 33b is provided (the left side in FIG. 4(A)) is made easier to protrude downward from within the thickness range of the plate material 13 than the main body part 32 on the main cutting edge 33a side. I can do it. This allows the displacement limiting portion 12a to easily come into contact with the main body portion 32 that protrudes downward on the side where the sub-cutting edge 33b is provided, on both sides in the thickness direction of the main body portion 32. The function of limiting the displacement of the cutting member 11 can be facilitated by contact with the displacement limiting portion 12a.

After creating a cut in the plate material 13 by the cutting process, as shown in FIG. 4B, the cutting member 11 is moved toward the advancing direction side (see FIG. Proceed to the right side of (B). In this case, since the cutting member 11 is rotatably provided around the support shaft 24b (see FIG. 3(A)), this rotational movement and the advancement of the cutting member 11 in the advancing direction are By combining, the lower end portion 31 of the cutting member 11 can be made to enter into the displacement limiting portion 12a. The operation of causing the lower end portion 31 of the cutting member 11 to enter the displacement limiting portion 12a may be performed by a driving force through a drive cable 24c (see FIG. 2(A)), or the cutting member 11 may move the plate material in the cutting process. The lower end portion 31 of the cutting member 11 may be moved into the displacement limiting portion 12a by the resistance force when cutting the portion 13.

Here, the angle of the main cutting edge 33a that is inclined with respect to the advancing direction of the cutting edge 33 (downward in FIG. 4(B)) when creating a cut in the plate material 13 in the cutting process, and the angle of the main cutting edge 33a when cutting the plate material 13 in the cutting process. The angle of the main cutting edge 33a that is inclined with respect to the direction of movement of the cutting edge 33 (to the right in FIG. 4B) is the angle in which the cutting member 11 rotates about the support shaft 24b in the direction of movement. The structure is such that the angle is likely to be greatly inclined relative to the surface. Therefore, the cut surface of the plate material 13 cut by the cutting edge 33 can be easily brought into a smooth state in any direction, and it is possible to easily manufacture a high-quality structural member.

FIG. 4(B) shows a state in which the cutting member 11 can freely rotate within its movable range without generating a driving force to the drive cable 24c (see FIG. 2(A)). (free state) and then advances the cutting member 11 in the cutting process. In this case, the lower portion of the cutting member 11 tends to advance more slowly than the upper portion due to the resistance force received from the plate member 13 against the force of the upper operating mechanism 24 that advances the upper portion of the cutting member 11 . Due to this delay, the lower end portion 31 of the cutting member 11 enters into the displacement limiting portion 12a, and the displacement of the cutting member 11 can be restricted by the displacement limiting portion 12a.

FIG. 5 is a diagram illustrating an operating mechanism when switching the cutting direction of the plate material 13 according to another embodiment. FIG. 5(A) shows that cutting of the plate material 13 in the cutting process is started while the cutting member 11 is maintained in the posture in the cutting process, and the lower end portion 31 of the cutting member 11 is cut into the area where the lower end 31 can enter into the displacement limiting portion 12a. After the cutting member 11 has advanced (the state shown by the solid line in FIG. 5(A)), the lower end portion 31 of the cutting member 11 has entered the displacement limiting portion 12a (the state shown by the dashed line in FIG. 5(A)). This shows the case of transitioning to the state shown in ). In this case, the control device 23 controls the driving force through the drive cable 24c (see FIG. 2(A)), and drives the cutting member 11 in a direction to maintain the posture in the cutting process in a certain section from the start of the cutting process. The force may be generated, and then the direction of the driving force may be switched to cause the lower end portion 31 of the cutting member 11 to enter the displacement limiting portion 12a.

FIG. 5(B) shows a case where the cutting member 11 is moved in the cutting process to a position below the height position corresponding to the cutting process in the cutting posture. As a result, a larger cut is formed in advance than when changing the moving direction of the cutting member 11 at a height position corresponding to the cutting posture, and a cut is made in a size that allows the lower end portion 31 of the cutting member 11 to enter into the displacement limiting portion 12a. The surface can be formed by a cutting process. In this case, the control device 23 controls the position of the cutting member 11 and the angle of the cutting member 11 due to the driving force through the drive cable 24c (see FIG. A driving force is generated in a direction to maintain the member 11 in the cutting posture, and then the direction of the driving force is switched to control the lower end portion 31 of the cutting member 11 to enter into the displacement limiting portion 12a. It's okay.

As described above, according to the plate material processing apparatus 10, when cutting the plate material 13, the upper operating mechanism 24 as a moving mechanism moves the cutting member 11 in the thickness direction of the plate material in the middle part away from the end of the plate material 13. By moving against, it is possible to generate a cut that spans the entire thickness direction in the middle of the cut. Then, the cutting member 11 can be advanced relative to the plate material 13 to cut the plate material 13 using the location where the cut is generated as a starting point. Therefore, when cutting the plate material 13, the restriction that the cutting must be performed starting from the end of the plate material 13 is reduced, and the plate material 13 can be cut efficiently and the cutting process with a high yield can be easily performed.

In addition, in the cutting process, a protruding tip position that protrudes downward from within the thickness range of the plate material 13 is provided at the edge portion on the advancing direction side (first direction side) where the cutting member 11 advances relative to the plate material 13. A main cutting edge 33a up to 36 is provided, and a secondary cutting edge 33b continuous with the main cutting edge 33a is formed in a length that continues to a part of the edge portion on the opposite side to the traveling direction side (second direction side). Therefore, compared to the case where the main cutting edge 33a is further extended to form the cutting member 11 in a substantially triangular shape without providing the secondary cutting edge 33b, the protruding tip position can be easily set at a large angle, and the plate material The strength of the cutting member 11 can be easily ensured while increasing the degree of freedom in the cutting process of the cutting member 13.

Further, in the above embodiment, a case has been described in which the displacement of a part of the cutting member 11 can be limited by the displacement limiting member 12, but the displacement limiting member 12 may be omitted, and even in this case, It is possible to efficiently cut the plate material 13 by creating a cut in the plate material 13 from a portion away from the end surface of the plate material 13 by the cutting member 11.
