  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Each of the embodiments described below exemplifies a method and an apparatus for embodying the technical idea of the present invention, and the technical idea of the present invention is not limited to the following. Absent. Various changes can be made to the technical idea of the present invention within the technical scope described in the claims.

  FIG. 1 is a plan view illustrating a configuration example of a plate processing apparatus 1 according to the embodiment. In the figure, the cutting section 2 and the cut forming section 3 are schematically shown. 2 and 3 are a front view and a side view showing a specific configuration example of the notch forming section 3. FIG. The plate processing apparatus 1 includes a pair of cutting units 2 and a pair of cut forming units 3.

  The cutting unit 2 includes a cutting cutter 21 (an example of a first cutter) that cuts the edge E of the plate material B. The notch forming section 3 includes a notch cutter 31 (an example of a second cutter) that cuts an edge E of the plate material B.

  In the following description, the X1 direction in the drawing is the forward direction, the X2 direction is the backward direction, the Y1 direction is the left direction, the Y2 direction is the right direction, the Z1 direction is the upward direction, and the Z2 direction is the downward direction. The forward direction is the direction of relative movement of the plate B. The rearward direction is the direction of relative movement of the cutter 21. The left-right direction is the width direction of the plate material B and the reciprocating direction of the cutting cutter 31.

  In the present embodiment, the plate material B is fixed, and the edge E of the plate material B is cut by moving the cutting cutter 21. However, the present invention is not limited to this, and the cutting cutter 21 is fixed and the plate material B is moved. Alternatively, the edge E of the plate material B may be cut.

  The plate material B is, for example, formed by laminating an impregnated paper impregnated with a resin material such as a melamine resin or a phenol resin on the surface of a substrate made of a plywood or a gypsum board, and is used for exteriors such as interiors of buildings and furniture. It is a decorative board.

  The plate material B is fixed on the table 71 by a pair of clamp portions 8 extending in the front-rear direction, and the edge portion E of the plate material B protrudes right and left outside of the clamp portion 8. The cutting cutter 21 moves rearward along the clamp portion 8 to cut the edge E of the plate material B protruding outward from the clamp portion 8 in the left and right direction.

  The cutting cutter 31 is located behind the cutting cutter 21. The cutter 21 and the cutter 31 are, for example, circular saws (tip saws). Not limited to this, the cutter 21 or the cutter 31 may be, for example, a jigsaw.

  The cutting section 2 includes a cutting cutter 21 and an electric motor (not shown) for driving the cutter 21. The cutting portion 2 is supported by a rail portion 49 extending in the front-rear direction so as to be movable in the front-rear direction. As shown in FIGS. 2 and 3, the rail portion 49 is disposed on a sub-table 73 provided in a laterally outward direction and a downward direction of the table 71 on which the plate material B is placed.

  An electric motor 23 (an example of a first driving unit) that moves the cutting unit 2 in the front-rear direction along the rail unit 49 is also arranged on the sub-table 73. The power of the electric motor 23 is transmitted to the cutting section 2 via a chain or a belt. A cut forming section 3 is connected to the cutting section 2, and the cut section 2 moves in the front-rear direction together with the cut forming section 3.

  Between the table 71 and the rail portion 49, there is provided a transport unit 9 for transporting the edge E of the plate material B cut off by the cutting cutter 21. The transport unit 9 is formed of, for example, a belt conveyor, and transports the edge E of the cut plate material B to a crusher (not shown). The power of the electric motor 23 is transmitted to the transport unit 9 via the shaft 24 (see FIG. 2).

  By the way, if the length of the edge E of the plate B cut off by the cutting cutter 21 remains the same as the length of the plate B in the front-rear direction, the edge E conveyed by the conveyance unit 9 protrudes from the conveyance unit 9. Therefore, there is a possibility that the operation of the cutting section 2 or the notch forming section 3 may be hindered, or the plate material B may be damaged.

  Therefore, in the present embodiment, the notch forming portion 3 for subdividing the edge E of the plate material B to be cut is provided.

  As shown in FIGS. 2 and 3, the cut forming unit 3 includes an electric motor 32, a driving pulley 33, a transmission belt 34, and a support 35 together with a cut cutter 31. The power of the electric motor 32 is transmitted from the driving pulley 33 attached to the output shaft of the electric motor 32 to the cutting cutter 31 via the transmission belt 34. The support portion 35 rotatably supports the cutting cutter 31.

  The cut forming section 3 supports the cut cutter 31 so as to be movable in the left-right direction and the front-rear direction. Specifically, the cut forming unit 3 includes the stands 41 to 43 stacked in three layers. The lower platform 41 (an example of a first platform) is supported by a rail 49 so as to be movable in the front-rear direction. The lower platform 41 extends forward and is fixed to the cutting section 2 (not shown in FIG. 3). For this reason, the notch forming part 3 moves in the front-back direction together with the cutting part 2.

  The middle platform 42 (an example of a third platform) is supported by the lower platform 41 so as to be movable in the front-rear direction by a rail structure provided between the middle platform 42 and the lower platform 41. The middle platform 42 moves in the front-rear direction with respect to the lower platform 41 by the operation of the electric cylinder 46 (an example of the third drive unit). Specifically, the cylinder portion 461 of the electric cylinder 46 is connected to the lower platform 41, and the rod portion 462 that advances and retreats with respect to the cylinder portion 461 is connected to the middle platform 42.

  The upper platform 43 (an example of the second platform) is supported by the rail structure provided between the upper platform 43 and the middle platform 42 so as to be movable in the left-right direction with respect to the middle platform 42. The upper platform 43 moves in the left-right direction with respect to the middle platform 42 by the operation of the electric cylinder 45 (an example of the second drive unit). Specifically, a cylinder portion 451 of the electric cylinder 45 is connected to the middle platform 42, and a rod portion 452 that advances and retreats with respect to the cylinder portion 451 is connected to the upper platform 43.

  The support portion 35 that supports the cutting cutter 31 and the electric motor 32 that drives the cutting cutter 31 are connected to the upper layer base 43. Thereby, the cutting cutter 31 can be moved in the left-right direction and the front-back direction with respect to the lower table 41 connected to the cutting section 2, and is operated in the left-right direction and the front-back direction by the operation of the electric cylinders 45 and 46. Moving. In addition, the moving direction of the middle stage 42 and the upper stage 43 may be switched.

  FIG. 4 is a block diagram illustrating an example of an electrical configuration of the cut forming unit 3. The notch forming section 3 includes the controller 10 connected to the electric motor 32 and the electric cylinders 45 and 46. In addition, the controller 10 may be connected to the electric motor 23 of the cutting unit 2 and the like.

  The controller 10 is a computer including a CPU, a RAM, a ROM, a nonvolatile memory, an input / output interface, and the like. The CPU executes information processing according to a program loaded from the ROM or the nonvolatile memory into the RAM. In the present embodiment, the controller 10 is, for example, a PLC (Programmable Logic Controller, a so-called sequencer).

  The electric motor 32 rotates the cutting cutter 31 in response to a command from the controller 10.

  The electric cylinder 45 moves the cutting cutter 31 in the left-right direction in response to a command from the controller 10 (see FIG. 2). That is, the electric cylinder 45 makes a cut extending in the left-right direction at the middle of the edge E of the plate material B in the front-rear direction by reciprocating the cutting cutter 31 in the left-right direction. Hereinafter, it is also referred to as “cutting electric cylinder 45”.

  The electric cylinder 46 moves the cutting cutter 31 in the front-rear direction in response to a command from the controller 10 (see FIG. 3). The electric cylinder 46 moves the cutter 31 in the forward direction, which is the direction of relative movement of the plate B, when the cutter 31 cuts into the edge E of the plate B. Hereinafter, it is also referred to as “the tuning electric cylinder 46”.

  FIG. 5 is a flowchart illustrating an example of a procedure of a sheet material processing method according to the embodiment, which is realized by the controller 10. FIG. 6 is a diagram for explaining an operation example of the cut forming unit 3 when the processing shown in FIG. 5 is executed.

  The processes and operations shown in FIGS. 5 and 6 are performed while the cutting unit 2 moves rearward and cuts the edge E of the plate material B with the cutting cutter 21. The cutting unit 2 moves rearward at a constant speed, for example.

  The cutting electric cylinder 45 reciprocates between a backward limit and a forward limit in the left-right direction. When the cutting electric cylinder 45 is at the backward limit, the tip of the cutting cutter 31 is in contact with the outermost edge of the edge E of the plate material B or opposes it with a slight gap (see FIG. 6A). On the other hand, when the cutting electric cylinder 45 is at the forward limit, the tip of the cutting cutter 31 bites into the edge E of the plate material B and comes into contact with the outer surface of the clamp portion 8 or opposes it with a slight gap (FIG. b)).

  The tuning electric cylinder 46 reciprocates between a backward limit and a forward limit in the front-rear direction. When the tuning electric cylinder 46 is at the backward limit, the cutting cutter 31 is farthest from the cutting cutter 21 (see FIG. 6A), and when the tuning electric cylinder 46 is at the forward limit, the cutting cutter 31 It comes closest to the cutter 21 (see FIG. 6C).

  When the process shown in FIG. 5 is started, the controller 10 moves the cutting cutter 31 in the left and right inward direction by moving the cutting electric cylinder 45 from the backward limit to the forward limit (S21, S22, FIG. a) → (b)), and thereafter, the cutting cutter 31 is moved outward in the left and right direction by moving from the forward limit to the backward limit (S23, S24, FIG. 6 (b) → (c)).

  While the cutting electric cylinder 45 reciprocates (S21 → S24), the controller 10 moves the cutting electric cylinder 46 from the backward limit to the forward limit to synchronize the cutting cutter 31 forward (S11). , S12, FIG. 6 (a) → (c)). Specifically, the cutting cutter 31 is moved at the same speed as the relative moving speed of the plate B (the moving speed of the cutting cutter 21 in the present embodiment) so that the relative position between the cutting cutter 31 and the plate B does not change. It is preferable to move with.

  Thereby, the cut S extending in the left-right direction is formed halfway in the front-rear direction of the edge E of the plate B while preventing the cutting cutter 31 from receiving a force in the thrust direction (force in the front-rear direction) from the plate B. Becomes possible.

  After that, the controller 10 moves the tuning electric cylinder 46 from the forward limit to the backward limit, thereby moving the cutting cutter 31 backward, and positioning the cutter 31 at the next cut forming position (S13, S14, FIG. 6). (C) → (d)). Further, when the tuning electric cylinder 46 reaches the reverse limit, the controller 10 generates a synchronization signal.

  While the tuning electric cylinder 46 moves to the reverse limit (S13), that is, until the synchronization signal is generated, the controller 10 causes the cutting electric cylinder 45 to wait (S26: NO). Then, when the tuning electric cylinder 46 reaches the backward limit (S14) and a synchronous signal is generated accordingly (S26: YES), the controller 10 reciprocates the cutting cutter 31 by the cutting electric cylinder 45 (S14). (S21 → S24) and the synchronized movement of the cutting cutter 31 by the synchronized electric cylinder 46 (S11, S12) are executed again.

  The series of processes described above is repeated until the cutting of the edge E of the plate material B by the cutting cutter 21 is completed (S15, S25: YES).

  FIG. 7 is a diagram for explaining an operation example of the cut forming unit 3 when the cutting cutter 21 is fixed and the plate material B is moved in the forward direction. Also in this case, the operation of the notch forming section 3 is the same as the operation described with reference to FIGS. 5 and 6, and the reciprocation of the notch cutter 31 in the left-right direction and the synchronized movement in the forward direction are simultaneously performed.

  According to the above-described embodiment, the plurality of cuts S are made in the middle of the edge E of the plate material B by the cutting cutter 31, so that the edge E of the plate material B to be cut can be subdivided. Becomes That is, when the cutting cutter 21 that cuts the edge E of the plate material B reaches the position of the cut S, a part of the edge E divided by the cut S falls. Therefore, a part of the edge E transported by the transport unit 9 (see FIG. 1 and FIG. 2) inhibits the operation of the cutting unit 2 or the notch forming unit 3 or the plate B from being damaged. It becomes possible.

  In the above embodiment, the cut S formed in the middle of the edge E of the plate B reaches the outer surface of the clamp portion 8, that is, the cut line of the cutter 21, and the edge E of the plate B is cut S However, the present invention is not limited to this. For example, the depth of the cut S is made shallower than the width of the edge E, and the edge E of the group of plate materials B having the plurality of cuts S is cut off. In this way, the edge E of the plate material B may be easily scattered or deformed on the transport unit 9.

  In the above-described embodiment, the cutting cutter 31 is located rearward of the cutting cutter 21 and cuts the edge E of the plate material B before cutting. However, the present invention is not limited to this. It may be configured so as to be located forward of the cutter 21 and to make a cut at the edge E of the plate material B after cutting.
