Description

Technical Field

[0001] The present invention relates to a laser processing machine.

Background Art

[0002] There is known a small-sized laser processing machine in which a work size of 4'×4' (1219 mm×1219 mm) is set as the maximum size capable of laser processing. This type of small-sized laser processing machine has a smaller overall apparatus compared to a large-sized laser processing machine capable of laser processing even on a large-sized work such as a 4'×8' (1219 mm×2438 mm) size work. The small-sized laser processing machine is excellent in that it can be installed in a limited space.

[0003] For example, Patent Document 1 discloses that laser processing is performed by closing an area other than the work on the upper surface of a processing table with a scattering prevention cover.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Users who own a small laser processing machine can of course use workpieces with sizes smaller than the processing range of the laser processing machine, such as a 4'×4' size. However, there are times when they have to use workpieces with sizes larger than the processing range, such as a 4'×8' size. Although a large-sized workpiece can be placed on the pallet of a small laser processing machine, a part of the workpiece will protrude outside the main body of the processing machine. A member for supplementarily supporting the area of the workpiece protruding outside the main body of the processing machine is separately required, or the processing has to be performed with the workpiece protruding outside the main body of the processing machine. For this reason, there is a problem that the influence on the periphery of the main body of the processing machine during workpiece processing is large.

Means for Solving the Problem

[0006] A laser processing machine according to an aspect of the present invention includes a main body of the processing machine, a pallet supported by the main body of the processing machine on which a workpiece is placed, and a processing head that irradiates a laser beam from above the workpiece placed on the pallet to perform laser processing on the workpiece. The pallet includes a processing area that supports the workpiece within a processing range in which laser processing can be performed by the processing head, and an extended area extended in a first direction from the processing area to support a workpiece with a size larger than the processing range. The extended area of the pallet is accommodated in a space portion formed on the first direction side of the processing range in the main body of the processing machine.

[0007] According to the laser processing machine of an aspect of the present invention, since the pallet that supports the workpiece is extended by the extended area, a workpiece with a size larger than the processing range can be placed on the pallet. Since the extended area of the pallet is accommodated in the space portion of the main body of the processing machine, it is possible to suppress the workpiece from protruding outside the main body of the processing machine during workpiece processing.

Effect of the Invention

[0008] According to an aspect of the present invention, it is possible to process a workpiece with a size larger than the processing range while suppressing the influence on the periphery of the main body of the processing machine during workpiece processing.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, with reference to the drawings, a laser processing machine according to the present embodiment will be described.

[0011] FIG. 1 is a side view schematically showing a main part of a laser processing machine according to the present embodiment. The laser processing machine 1 according to the present embodiment includes a processing machine main body 10, a pallet 50 supported by the processing machine main body 10 on which a work W is placed, and a processing head 30 that irradiates a laser beam from above the work W placed on the pallet 50 to perform laser processing on the work W. The pallet 50 includes a processing area A1 that supports the work W within a processing range R in which laser processing can be performed by the processing head 30, and an extended area A2 that is extended in a first direction from the processing area A1 to support a work W having a size larger than the processing range R. The extended area A2 of the pallet 50 is accommodated in a space portion S formed on the first direction side of the processing range R in the processing machine main body 10.

[0012] Hereinafter, the laser processing machine according to this embodiment will be described in detail. In this specification, the left-right direction and the front-rear direction orthogonal to each other in the horizontal direction, and the up-down direction orthogonal to the left-right direction and the front-rear direction respectively are used as the definitions of directions. Among the left-right direction, the right direction corresponds to the first direction, and the left direction corresponds to the second direction.

[0013] The laser processing machine 1 includes a processing machine main body 10, a processing head 30, and a pallet 50.

[0014] The processing machine main body 10 includes a base 11, side frames 12, and a head drive mechanism 15.

[0015] The base 11 is generally configured in a rectangular parallelepiped shape and is installed on an installation surface such as a floor surface.

[0016] The side frames 12 are respectively arranged at the front edge portion and the rear edge portion of the base 11. In FIG. 1, for convenience of explanation, the description of the side frame 12 at the front edge portion is omitted. The side frames 12 at the front edge portion and the rear edge portion are arranged parallel to each other.

[0017] The head drive mechanism 15 is a mechanism that moves the processing head 30 along the workpiece W, and includes an X-axis carriage 16 and a Y-axis carriage 19. The X-axis carriage 16 has a portal shape composed of a pair of columns 17 and a beam 18 extending in the front-rear direction so as to straddle between the pair of columns 17. In FIG. 1, similar to the side frame 12 at the front edge portion, the description of the front column 17 is omitted.

[0018] The X-axis carriage 16 is supported by a pair of side frames 12 and is configured to be movable along the side frames 12. The X-axis carriage 16 is driven by an X-axis carriage drive unit (not shown) provided on the side frames 12 and moves in the left-right direction.

[0019] The Y-axis carriage 19 is arranged on the X-axis carriage 16. The Y-axis carriage 19 is supported by the beam 18 of the X-axis carriage 16 and is configured to be movable along the beam 18. The Y-axis carriage 19 is driven by a Y-axis carriage drive unit (not shown) provided on the beam 18 and moves in the front-rear direction.

[0020] The machine tool main body 10 further has a control panel 100, a laser oscillator 110, etc. The control panel 100 controls the operation of the laser processing machine 1. The control panel 100 is composed of a box-shaped housing, a circuit board housed inside the housing, etc. The laser oscillator 110 generates a laser beam and supplies the laser beam to the processing head 30. The laser oscillator 110 is composed of a box-shaped housing, electronic components and electrical components housed inside the housing, etc.

[0021] The control panel 100 and the laser oscillator 110 are arranged on the base 11 of the machine tool main body 10. Specifically, the control panel 100 is arranged below the right end of the base 11 and is fixed to the base 11. The laser oscillator 110 is arranged above the right end of the base 11 and is fixed to the base 11. The laser oscillator 110 is arranged above the control panel 100, and a space part S serving as a gap is formed between the laser oscillator 110 and the control panel 100.

[0022] The processing head 30 irradiates a laser beam from above the workpiece W to perform laser processing on the workpiece W. A laser beam emitted from the laser oscillator 110 is transmitted to the processing head 30 via a process fiber (not shown). The laser beam transmitted to the processing head 30 is irradiated onto the workpiece W from the opening at the tip of the processing head 30 after passing through an optical system provided inside the processing head 30.

[0023] The processing head 30 is fixed to the Y-axis carriage 19 of the head drive mechanism 15. Therefore, by driving the X-axis carriage drive unit and the Y-axis carriage drive unit to move the X-axis carriage 16 and the Y-axis carriage 19, the processing head 30 can be moved in the left-right direction and the front-rear direction, respectively.

[0024] Through the movement by the head drive mechanism 15, the processing head 30 can perform laser processing within a predetermined processing range R. The laser processing machine 1 of the present embodiment is a device assuming a small-sized workpiece W, and the processing range R is set to a range capable of processing a workpiece W having a maximum size of 4'×4'.

[0025] FIG. 2 is a perspective view showing a pallet included in the laser processing machine. FIG. 3 is a top view schematically showing the pallet shown in FIG. 2. FIG. 4 is a diagram for explaining the relationship between the size of the pallet and the workpiece. FIG. 5 is an explanatory view showing a state in which the second workpiece support portion stands up on the pallet. FIG. 6 is a diagram for explaining the height of the workpiece supported by the first workpiece support portion and the second workpiece support portion, respectively. FIG. 7 is an explanatory view showing a state in which the pallet is pulled out to the pull-out position.

[0026] As shown in FIG. 1, the pallet 50 is supported by the machine body 10 of the processing machine, and the workpiece W is placed thereon. The pallet 50 includes a frame body 51 for supporting the workpiece W.

[0027] The frame body 51 is a substantially rectangular frame member that is horizontally long in the left-right direction in a top view. The length of the frame body 51 in the left-right direction is substantially the same as the length of the machine body 10 in the left-right direction including from the left end of the base 11 to the control panel 100 and the laser oscillator 110 connected to the base 11.

[0028] The pallet 50 includes a processing area A1 and an extended area A2. The processing area A1 is an area for supporting the workpiece W within the processing range R. On the other hand, the extended area A2 is an area extended rightward from the processing area A1 to support a workpiece W having a size larger than the processing range R.

[0029] The laser processing machine 1 of this embodiment has a processing range R corresponding to a workpiece W of 4'×4' size. On the other hand, in addition to the processing area A1, an extended area A2 is provided on the pallet 50. By providing the pallet 50 with the extended area A2, a workpiece with a size larger than the 4'×4' size workpiece W, for example, a workpiece W of 4'×8' size, can be supported only by the pallet 50.

[0030] As shown in FIG. 2, the processing area A1 of the pallet 50 includes a plurality of skids 52.

[0031] The plurality of skids 52 are plate-like members that support the workpiece W in the processing area A1. The plurality of skids 52 are arranged at intervals in the left-right direction. Each skid 52 is a plate-like member extending in the front-rear direction and is made of a metal material such as steel, for example, mild steel. The skid 52 is arranged so as to span between a pair of frame members 51a that constitute the frame body 51, and both ends of the skid 52 are fixed to each of the pair of frame members 51a. The skids fixed to the frame body 51 stand upright, for example, vertically. However, the skid 52 only needs to stand upright in the vertical direction and does not necessarily have to be vertical.

[0032] Each skid 52 is provided with a plurality of protrusions that protrude upward. The plurality of protrusions are provided at the upper end of the skid 52. The plurality of protrusions are provided at intervals in the front-rear direction. Each protrusion is a vertically long plate body along the vertical direction and has a mountain shape in which the width becomes narrower toward the upper end. The workpiece W is supported at the top of the skid 52, that is, at the apex of each protrusion.

[0033] The extended area A2 of the pallet 50 includes a plurality of first workpiece support portions 55 and a pallet cover 56.

[0034] The plurality of first work supports 55 support the work W in the extended area A2. Each first work support 55 is constituted by, for example, a free bearing having a rotatable sphere.

[0035] The plurality of first work supports 55 are arranged corresponding to the size of a standardized material which is a work with a predetermined size. In the example shown in FIG. 4, the first work supports 55 are respectively arranged at two positions, front and rear, at the right end of a work W1 with a size of 3'×6' (910 mm×1820 mm), and the first work supports 55 are respectively arranged at two positions, front and rear, at the right end of a work W2 with a size of 1000 mm×2000 mm. Also, the first work supports are respectively arranged at three positions, front, rear, and center, at the right end of a work W3 with a size of 4'×8', and at one position slightly to the right and at the rear end of the central portion in the left - right direction of the work W1. Thus, the plurality of first work supports 55 are arranged corresponding to the edges of the work W made of standardized materials.

[0036] As shown in FIG. 2, the pallet cover 56 is arranged so as to span between a pair of frame members 51a. The pallet cover 56 is a flat - plate - shaped member, and the space between the pair of frame members 51a is covered by the pallet cover 56. The pallet cover 56 is made of a metal material such as steel. Openings are formed in the pallet cover 56 corresponding to the plurality of first work supports 55.

[0037] Each first work support 55 protrudes upward from the pallet cover 56 through the opening of the pallet cover 56. The upper end of each first work support 55 is located at a position higher than the upper surface of the pallet cover 56. Specifically, as shown in FIG. 6, the height of each upper end of the first work support 55 is set to the same height as the pass - line L1 of the work W supported by the plurality of skids 52.

[0038] Also, as shown in FIGS. 3 and 6, the processing area A1 of the pallet 50 further includes a plurality of second work support portions 57 and a plurality of clamp portions 53 in addition to the plurality of skids 52.

[0039] The plurality of second work support portions 57 support the work W in the processing area A1 during setup work of the work W or the like. Each second work support portion 57 is constituted by, for example, a free bearing including a rotatable sphere.

[0040] The plurality of second work support portions 57 are fixed to a plurality of rods 58. The plurality of rods 58 are arranged at intervals in the front-rear direction. Each rod 58 is a shaft body extending in the left-right direction and is fixed to the frame body 51 in a rotatable state around the axis center. A handle 59 that can be rotationally operated by the user is attached to the frame body 51. The handle 59 and the plurality of rods 58 are connected via a power transmission mechanism, and when the handle 59 is rotationally operated, the individual rods 58 also rotate synchronously.

[0041] The second work support portion 57 fixed to the rod 58 can be switched between an upright state and a tilted state according to the rotation angle of the rod 58. As shown in FIG. 5, when the second work support portion 57 is in the upright state, the upper portion of the second work support portion 57 protrudes above the apex (the apex of the protruding portion) of the skid 52. In this state, the work W on the processing area A1 is supported by the upright second work support portion 57. As shown in FIG. 6, the second work support portion 57 supports the work W at a line L2 higher than the pass line L1.

[0042] On the other hand, when the second work support portion 57 is in the tilted state, the second work support portion 57 retracts below the apex (the apex of the protruding portion) of the skid 52. In this state, the work W on the processing area A1 is supported by the apexes (the apexes of the protruding portions) of the plurality of skids 52.

[0043] As shown in FIG. 2, a plurality of clamp portions 53 fix the work W supported by the skid 52 in the machining area A1. The plurality of clamp portions 53 are fixed to the frame member 51a that constitutes the frame body 51.

[0044] As shown in FIG. 1, the pallet 50 having such a configuration is configured to be movable in the left-right direction via the guide member 13 fixed to the base 11. The guide member 13 guides the linear motion of the pallet 50 by slidably holding the rail provided on the frame body 51 of the pallet 50.

[0045] When the pallet 50 is in the normal position, specifically, when the pallet 50 is located at the far right rear, the machining area A1 of the pallet 50 is located within the machining range R (see FIG. 1). Further, the expansion area A2 of the pallet 50 enters the space S, which is a gap formed between the control panel 100 and the laser oscillator 110.

[0046] When the pallet 50 is pulled out to the left, the pallet 50 moves from the normal position to the pulled-out position. The pulled-out position is a position where the machining area A1 of the pallet 50 is pulled out to the left of the machining range R (see FIG. 7). The pallet 50 can move between the pulled-out position and the normal position.

[0047] Next, the operation of the laser processing machine 1 according to the present embodiment will be described. When performing the setup work of setting the work W on the pallet 50, first, the user pulls out the pallet 50 to the pulled-out position (see FIG. 7). When the pallet 50 is pulled out to the pulled-out position, the expansion area A2 of the pallet 50 is pulled out from the space S. Thereby, the work W can be separated from the components and structures on the far right rear side of the processing machine main body 10. Therefore, interference between the work W and the processing machine main body 10 can be suppressed, and the handling of the work W when setting the work W on the pallet 50 becomes easy. In particular, in the present embodiment, the work W can be placed over the entire area of the pallet 50 including the machining area A1 and the expansion area A2. Even for a work W having a large size such as 4'×8', the work W can be easily set.

[0048] Also, as shown in FIGS. 4 and 6, when setting the work W on the pallet 50, the user operates the handle 59 to raise the plurality of second work support portions 57. As a result, in the processing area A1, the work W is supported by the plurality of second work support portions 57, and in the expansion area A2, the work W is supported by the plurality of first work support portions 55. Therefore, the work W can be smoothly moved on the pallet 50 without contacting the skid 52.

[0049] When the setting of the work W on the pallet 50 is completed, the user pushes the pallet 50 into the normal position. When the pallet 50 is pushed into the normal position, the processing area A1 of the pallet 50 is located within the processing range R (see FIG. 1). The control panel 100 can perform laser processing within the processing range R while moving the processing head 30 by controlling the head drive mechanism 15. Thereby, laser processing can be performed on one side area (area of 4'×4' size) of the work W located in the processing area A1.

[0050] When the laser processing on one side area of the work W is completed, the user pulls out the pallet 50 to the pull-out position (see FIG. 7). When the pallet 50 is pulled out to the pull-out position, the expansion area A2 of the pallet 50 is pulled out from the space portion S. Thereby, the work W can be separated from the components and structures on the right back side of the processing machine main body 10. Since interference between the work W and the processing machine main body 10 can be suppressed, the setup of the work W, such as rotating the work W by 180 degrees or reversing it left and right, can be easily performed. And by this setup work, the remaining half area of the work W can be replaced with the processing area A1 of the pallet 50.

[0051] When the rotation or inversion of the workpiece W is completed, the user pushes the pallet 50 into the normal position. When the pallet 50 is pushed into the normal position, the processing area A1 of the pallet 50 is located within the processing range R (see FIG. 1). The control panel 100 can perform laser processing within the processing range R while moving the processing head 30 by controlling the head drive mechanism 15. Thereby, laser processing can be performed on the remaining area (4'×4' size area) of the workpiece W newly set in the processing area A1.

[0052] As described above, according to the laser processing machine 1 according to this embodiment, since the pallet 50 that supports the workpiece W is expanded by the expansion area A2, a workpiece W having a size larger than the processing range R can be placed on the pallet 50. Further, since the expansion area A2 of the pallet 50 is accommodated in the space portion S of the processing machine main body 10, it is possible to suppress the workpiece W from protruding outside the processing machine main body 10 during the processing of the workpiece W.

[0053] According to this laser processing machine 1, it is possible to process a workpiece W having a size larger than the processing range R without affecting the surroundings of the processing machine main body 10 during the processing of the workpiece W.

[0054] When processing a large-sized workpiece W, it is also conceivable to cut the workpiece W in advance to a size that fits within the processing range R and then place it on the pallet 50 of the laser processing machine 1. However, since the operation of cutting the workpiece W in advance is required, the work efficiency is poor. In this regard, according to the laser processing machine 1 according to this embodiment, the workpiece W can be placed on the pallet 50 without cutting the workpiece W in advance.

[0055] In this embodiment, the processing machine main body 10 supports the pallet 50 so as to be movable along the right direction and the left direction. The pallet 50 moves between a pull-out position where the processing area A1 is pulled out to the left of the processing range R and a normal position where the processing area A1 is within the processing range R.

[0056] According to this configuration, the pallet 50 can be pulled out from the processing machine main body 10. Since the extended area A2 of the pallet 50 is pulled out from the space part S, the workpiece W placed on the pallet 50 can be separated from the structure of the processing machine main body 10 such as the laser oscillator 110. Thereby, the setup work of setting the workpiece W on the pallet 50 can be easily performed.

[0057] In the present embodiment, the pallet 50 is composed of a rectangular frame body 51. The processing area A1 is respectively arranged so as to straddle between a pair of frame members 51a constituting the frame body 51, and has a plurality of skids (plate-like members) 52 provided with a plurality of mountain-shaped protrusions for supporting the workpiece W. The extended area A2 has a pallet cover 56 arranged so as to cover between the pair of frame members 51a, and a plurality of first workpiece support portions 55 that protrude above the pallet cover 56 and support the workpiece W.

[0058] According to this configuration, in the extended area A2, the workpiece W can be supported by the plurality of first workpiece support portions 55. By optimizing the arrangement of the first workpiece support portions 55, the workpiece W extending from the processing area A1 can be supported well in balance. Thereby, deflection or the like generated in the workpiece W can be suppressed.

[0059] Further, the extended area A2 is covered by the pallet cover 56. Since the pallet cover 56 can cover the opening of the frame body 51, it can also serve to block light from the laser beam and prevent the scattering of spatter.

[0060] In the present embodiment, each of the plurality of first workpiece support portions 55 is constituted by a free bearing having a rotatable sphere.

[0061] According to this configuration, even in a state supported by the first workpiece support portion 55, the slide movement of the workpiece W can be easily performed. Thereby, the workability when performing the setup work of the workpiece W can be improved.

[0062] In this embodiment, the height of the upper end of each of the plurality of first work support portions 55 is set to the same height as the pass line L1 of the work W supported by the plurality of skids 52.

[0063] According to this configuration, even in the extension region A2, the work W is supported along the pass line L1. Thereby, it is possible to suppress the occurrence of deflection of the work W in the extension region A2, and thus the occurrence of deflection of the work W in the processing region.

[0064] In this embodiment, the processing region A1 is configured to be switchable between an upright state and a tilted state, and has a plurality of second work support portions 57 that support the work. Each of the plurality of second work support portions 57 protrudes upward from the apex of the protruding portion of the skid 52 in the upright state, and retracts downward from the apex of the protruding portion of the skid 52 in the tilted state. Each of the plurality of second work support portions 57 is constituted by a free bearing provided with a rotatable sphere.

[0065] According to this configuration, by keeping the second work support portion 57 upright, the second work support portion 57 protrudes upward from the skid 52. Therefore, the work W in the processing region A1 is supported by the second work support portion 57. Since the work W can be easily moved on the pallet 50, the workability when setting up the work W can be improved. In addition, even when being supported by the second work support portion 57, the work W can be easily slid. Thereby, it is possible to improve the workability when performing the setup work of the work W.

[0066] The plurality of first work support portions 55 are arranged corresponding to the size of the standard material which is the work W with a predetermined size.

[0067] According to this configuration, since the first workpiece support portion 55 is arranged in anticipation of the size of the cut-to-length material, the workpiece W can be appropriately supported so that deflection or the like does not occur. Further, the first workpiece support portion 55 is not arranged at an unnecessary position. As a result, the first workpiece support portion can be efficiently arranged, so that an unnecessary cost increase can be suppressed.

[0068] In the present embodiment, the processing machine main body 10 includes a laser oscillator 110 that is arranged on the right side of the processing range R and supplies a laser beam to the processing head 30, and a control panel 100 that is arranged on the right side of the processing range R and controls the laser oscillator 110. In this case, the space portion S is formed between the laser oscillator 110 and the control panel 100.

[0069] According to this configuration, the extended area A2 of the pallet 50 can be accommodated by utilizing the gap between the laser oscillator 110 and the control panel 100. By effectively using the gap in the processing machine main body 10, it is possible to suppress the workpiece W from protruding outside the processing machine main body 10.

[0070] Note that, in the above-described embodiment, the extended area A2 of the pallet 50 includes a plurality of first workpiece support portions 55 and a pallet cover 56. However, the extended area A2 may include only the pallet cover 56 without including a plurality of first workpiece support portions 55. Further, although a free bearing is exemplified as the first workpiece support portion 55, a roller or the like may be used. Furthermore, the extended area A2 may have a configuration including a plurality of skids 52 instead of the pallet cover 56.

[0071] As described above, the embodiments of the present invention have been described, but it should not be understood that the discussions and drawings forming a part of this disclosure limit this invention. Various alternative embodiments, examples, and operation techniques will be apparent to those skilled in the art from this disclosure.
