Description

  The present invention relates to a composite processing apparatus for plate materials and a composite processing method using this apparatus.

  Conventionally, for example, a punch / laser combined processing apparatus 201 as a combined processing apparatus for plate materials cooperates with a punch P and a die D mounted on an upper turret 203 and a lower turret 205 as shown in FIG. And a punching unit 207 that performs punching, and a laser processing unit 209 that performs laser processing and includes a laser processing head as shown in FIG. The laser processing unit 209 can move the laser center L / C in the Y-axis direction, for example, 1270 mm. Further, a carriage 217 provided with a clamp device 215 for clamping the workpiece W is provided on a machining base 211 movably provided in the Y-axis direction so as to be movable in the X-axis direction.

  Accordingly, the workpiece W clamped by the clamping device 215 is moved and positioned on the machining table 211 in the X-axis direction and the Y-axis direction, and punching and laser machining are performed in the machining portions 207 and 209.

  As the processing table 211, a brush table in which a large number of brushes 219 are implanted is used in order to prevent scratches when transporting a workpiece W that has been punched or, for example, a workpiece W molded downward 10 mm. ing. Further, there is a configuration in which a brush table and a shooter table 221 provided with a number of free bears are switched.

  In spite of the growing demand for downward molding in recent years, large-scale work shooters are being developed for batch delivery of large product skeletons.

  Referring also to FIG. 20, the shooter table 221 is provided with two cutting plates 223 on both sides of the laser centers L and C, and a number of free bears 225 are disposed outside the two cutting plates 223. ing.

Referring to FIGS. 21A and 21B, as another conventional example, a shooter table 221 substantially the same as described above is provided by a lifting cylinder 227 so as to be lifted and lowered by, for example, a stroke of 70 mm. On the outside of the shooter table 221, a brush table 229 is provided so as to be slidable in a horizontal direction, for example, with a stroke of 500 mm, to an upper position of the shooter table 221 where the brush table 229 is lowered. Therefore, during laser processing, the shooter table 221 ascends to the pass line PL as shown in FIG. 21A to support the workpiece W, and during punching as shown in FIG. 21B. After the shuter table 221 descends, the brush table 229 moves to the upper position of the shooter table 221 from the right direction as indicated by an arrow, for example, and the work W is supported by the brush table 229 (see, for example, Patent Document 1). .
JP 2003-33832 A

  By the way, in the conventional punch / laser combined machining apparatus 201 in FIG. 20, the condition of the work shooter at the time of laser machining is that the shooter table 221 is made of metal in which a large number of free bears 225 are arranged due to heat resistance. Further, the cutting plate 223 is also made of metal, and laser processing cannot be stabilized unless the pass line PL is constant.

  Therefore, when the workpiece W enters the area of the shooter table 221, the cutting speed of the laser is reduced to prevent gouging (defective cutting processing) due to upper and lower flapping of the workpiece W. However, the possibility of the occurrence of gouging still exists and the cutting speed is reduced, so the processing speed is reduced, and the downward molding part 231 of the workpiece W is scratched. Since the dead zone DZ is present, there is a problem that laser processing in the vicinity of the downward molding portion 231 cannot be performed.

  Therefore, the downward molding portion 231 is basically prohibited from entering between the two cutting plates 223 as a dead zone DZ.

  Further, in the conventional punch / laser combined machining apparatus 201 shown in FIGS. 21A and 21B, since the position of the downward molding portion 231 is known in advance, the NC control at the time of machining is performed downward by the program before machining. It can be controlled to switch to the specification of the brush table 229 when the vicinity of the molding part 231 enters the so-called dead zone DZ. However, since the responsiveness of the switching is not good, there is a problem that the processing efficiency is lowered.

  In addition, when the shooter table 221 is moved up and down, the workpiece and the product are lowered from the pass line PL particularly when the workpiece W is a thin plate.

  Furthermore, when the brush table 229 slides, there is a problem that the work W is damaged because the work W jams.

  With the above configuration, when the X-axis drive motor 47 is driven, the carriage 43 is moved in the X-axis direction, that is, the vertical direction in FIG. One end of the carriage base 41 is connected to a Y-axis drive motor 49. By driving the Y-axis drive motor 49, the carriage base 41 is moved in the Y-axis direction, that is, in the left-right direction in FIG. It will be. Accordingly, the workpiece W gripped by the clamping device 45 is moved in the X-axis and Y-axis directions, and is moved and positioned at a desired machining position of the punch center P / C or the laser center L / C.

  Next, the shooter table 39 according to the first embodiment will be described with reference to the drawings.

  Referring to FIGS. 1, 5A to 5C, 6 and 7A and 7B, there are two on both sides of the laser center L / C in the laser processing head 25 described above. Cutting plates 51 are juxtaposed, and the respective cutting plates 51 are provided so as to be movable up and down independently of each other by front and rear CP (cutting plate) lifting cylinders 53F and 53R. The front and rear CP elevating cylinders 53F and 53R are connected to the control device 55 as shown in FIG.

  The shooter table 39 includes the two cutting plates 51 described above. A plurality of roll brushes 59 are provided in parallel to the two cutting plates 51 on the table frame 57 of the shooter table 39. Yes. That is, one end side of the plurality of roll brushes 59 On the right side in FIG. 6, a plurality of rotation shafts 61 arranged side by side are rotatably supported by the table frame 57. As shown in FIGS. 7A and 7B, for example, a free bear 63 as a large number of rotating members is rotatably provided by a housing 65. In addition, a large number of brushes 67 serving as brush portions 67 are implanted on the other semi-periphery of each rotary shaft 61 on the opposite side of the free bear 63 of the housing 65.

  In this embodiment, as shown in FIG. 6, six roll brushes 59 are provided on the table frame 57 on the front side of the two cutting plates 51, and 1 on the table frame 57 on the rear side. A book roll brush 59 is provided. In FIG. 5, two roll brushes 59 are shown in the front table frame 57 for easy understanding.

  The brush rotation mechanism for rotating the plurality of roll brushes 59 will be described with the six roll brushes 59 on the front side. As shown in FIGS. 6 and 8B, the rotation of each roll brush 59 is rotated. A timing pulley 69 is provided on one end side of the shaft 61, and a timing belt 71 meshing with the six timing pulleys 69 is wound in an endless ring shape. Further, a pinion 73 is provided at the end of the rotation shaft 61 of one of the six roll brushes 59, and a rack 75 meshing with the pinion 73 is a brush rotation cylinder 77F on the front side. 8B is provided so as to be reciprocally movable in the left-right direction in FIG. Note that the single roll brush 59 on the rear side is substantially the same, and in this case, since it is one, it is directly rotated by the brush rotation cylinder 77R on the rear side by the mechanism of the rack 75 and the pinion 73. It is configured as follows. The front and rear brush rotation cylinders 77F and 77R are connected to the control device 55.

  Therefore, in FIG. 8A, the six roll brushes 59 are in the free bear table state with the free bear 63 positioned above. This is because the rack 75 moves in the left direction in FIG. 8B, so that the pinion 73 of one roll brush 59 rotates 180 ° in the clockwise direction. In this state, 61 is rotated 180 ° clockwise via a timing pulley 69 meshing with the timing belt 71.

  In FIG. 9A, the plurality of roll brushes 59 are in a brush table state with the brush portion 67 positioned above. This is because when the rack 75 moves to the right in FIG. 9B, the pinion 73 of one roll brush 59 rotates 180 ° counterclockwise, and the other roll brush 59 rotates accordingly. The shaft 61 is rotated 180 ° counterclockwise via a timing pulley 69 that meshes with the timing belt 71.

  As described above, with the simple structure of the rack 75 and the pinion 73, the free bear table and the brush table can be switched at high speed in a short time, and the switching response is high.

  In the above-described embodiment, the timing pulley 69 and the timing belt 71 are provided. However, the pinion 73 is provided on the rotating shaft 61 of all the roll brushes 59, and all the pinions 73 are meshed with the rack 75 so as to be driven to rotate simultaneously. It may be configured as above, or another rotational drive mechanism.

  Referring to FIG. 5A again, the laser processing head 25 detects that the marking of the downward molding portion DF has entered the identification area FA or RA of the shooter table 39 including the two cutting plates 51. Side and rear side marking identification devices 79F and 79R are provided. In FIG. 5A, the left front-side marking identification device 79F detects the marking of the downward molding portion DF of the front-side identification area FA, and the right rear-side marking identification device 79R is located in the rear-side identification area RA. The marking of the downward molding part DF is detected. In FIG. 5A, the identification area FA and the identification area RA are large and small (the identification area RA has a smaller area), but this is for convenience and not related thereto. Rather, it is reasonable to equate the area.

  Referring to FIG. 10, in the control device 55, an input device 83 such as a keyboard and a display device 85 such as a CRT or LCD are connected to a CPU 81 as a central processing unit.

  The CPU 81 is connected to a memory 87 for storing data such as a machining program including a size and a shape of the workpiece W input from the input device 83, punching machining, and laser machining instructions.

  Further, the CPU 81 rotates the corresponding front side and / or rear side roll brush 59 by the detection signal detected by the front side and / or rear side marking identification devices 79F, 79R to rotate the brush table. And a work shooter command unit 89 for giving a command to lower the cutting plate 51 on the front side and / or the rear side. The work shooter command unit 89 also gives a command to perform the reverse operation when no marking is detected by the front and / or rear side marking identification devices 79F and 79R. That is, the brush table mode is used during punching, and the free bear table mode is used during laser processing.

  With the above configuration, referring to FIGS. 5A to 5C and FIG. 11, when punching is performed on the plate-like workpiece W by the punching unit 9, the plurality of roll brushes 59 of the shooter table 39 are arranged. The rotating shaft 61 is rotated, the free bear 63 is positioned upward to be in a free bear table state, and the workpiece W is supported by a number of free bears 63. This is the state of FIG.

  When the workpiece W is molded downward by the punching unit 9, the marking unit 23 marks the downward molded unit DF. The marking itself does not need to cover the entire downward molding portion DF, and can be identified if it is marked on the upper surface of the downward molding portion DF (steps S1 to S2).

  When laser processing is performed on the workpiece W by the laser processing head 25, the workpiece W is moved, and when the downward molding portion DF of the workpiece W enters the front side identification area FA with respect to the cutting plate 51, the front side Is detected by the marking identification device 79F.

  A command is given from the work shooter command section 89 by this detection signal, and the rotation shaft 61 of the six roll brushes 59 in the front identification area FA is rotated 180 ° so that the brush section 67 is positioned upward and the brush table. The workpiece W is supported by the brush portion 67. Furthermore, the cutting plate 51 on the front side is lowered by, for example, 12 mm in this embodiment. This is the state of FIG. Therefore, since the downward molding part DF can pass through the cutting plate 51 on the front side, laser processing in the vicinity of the downward molding part DF is performed without any delay (steps S3 to S7).

  When the downward molding portion DF leaves the front side identification area FA and enters the rear side identification area RA, a command is given from the work shooter command unit 89, and the six roll brushes in the front side identification area FA are provided. The rotation shaft 61 of 59 is rotated by 180 ° so that the free bear 63 is positioned upward to be in a free bear table state, and the workpiece W is supported by a number of free bears 63. The front-side cutting plate 51 is raised and returned to the original position, while the rear-side cutting plate 51 is lowered by, for example, 12 mm. This is the state of FIG. Therefore, since the downward molding part DF can pass through the rear-side cutting plate 51, the laser processing in the vicinity of the downward molding part DF is performed without any delay (steps S8 to S11).

  After the laser processing, when the downward molding portion DF is withdrawn from the rear-side identification area RA, the rear-side cutting plate 51 is raised and returned to the original position, and the rear-side roll brush 59 is in a free bear table state (step) S12 to S13).

  The shooter table 39 is opened and the product is carried out (steps S14 to S15). The above operation is automatically performed by the control device 55.

  From the above, since the downward molding portion DF is detected by the marking identification devices 79F and 79R, for example, a response of about 1/100 second is possible. Further, since the roll brush 59 can be switched between the free bear table surface and the brush table surface at a high speed only by rotating the roll brush 59 by 180 °, the switching response is improved. Further, when the downward molding portion DF enters the identification area FA or RA, the brush table surface is switched and the cutting plate 51 is lowered, so that the conventional dead zone of the downward molding portion DF is eliminated. Moreover, gouging is eliminated and product quality is improved.

  Next, a shooter table 91 according to the second embodiment will be described with reference to the drawings. Note that members similar to those of the shooter table 39 of the first embodiment described above are described with the same reference numerals.

  12 and 15 together, two cutting plates 51 are arranged in parallel on both sides of the laser center L / C in the laser processing head 25, and the shooter table 91 includes the two cutting plates. 51 is provided. On the upper surface of the shooter table 91, a plurality of slot portions 93 are arranged in parallel to the outside of the two cutting plates 51, and the upper surface between the slot portions 93 is, for example, a rotating member. A number of free bears 63 are provided. In this embodiment, four slots 93 are provided on the front side, and two slots 93 are provided on the rear side.

  Further, the shooter table 91 is provided so as to be movable up and down by a table elevating cylinder 97 attached to the shooter base 95 as shown in FIG. Although not shown, the table elevating cylinder 97 is connected to and controlled by the control device 55 described above.

  The shooter table 91 is provided with a plurality of roll brushes 99 that are supported by the shooter base 95. In this embodiment, four roll brushes 99 on the front side and two roll brushes 99 on the rear side are provided along each of the groove portions 93 described above. That is, in the six roll brushes 99, the six rotation shafts 61 are rotatably supported by the shooter base 95 via the support members 101 along the respective slot portions 93. A base portion 103 is provided over almost the entire length, and the brush base portion 103 is provided with a cover portion 105 for closing the slot portion 93 as shown in FIG. ing. In addition, on the other semi-peripheral side of the brush base portion 103 of each rotating shaft 61, a large number of brushes as the brush portion 107 are implanted so that they can be inserted into the respective slot portions 93 on the opposite side to the cover portion 105. Has been.

  Referring to FIGS. 16 and 17, as a brush rotation mechanism for rotating the plurality of roll brushes 99, a pinion 73 is provided on one end side of the rotation shaft 61 of each roll brush 99. A meshing rack 75 is provided by a brush rotating cylinder 77 with a guide so as to reciprocate in the left-right direction in FIG. The brush rotation cylinder 77 is connected to and controlled by the control device 55, which is not shown.

  Therefore, in FIG. 13, the plurality of roll brushes 99 are in the brush table state with the brush portion 107 positioned above. For example, when the rack 75 moves leftward in FIG. 17, the pinion 73 of each roll brush 99 rotates 180 ° in the clockwise direction, and accordingly, the rotation shaft 61 of each roll brush 99 rotates clockwise. It is in a state rotated 180 ° in the direction.

  In FIG. 14, the plurality of roll brushes 99 are in a free bear table state in which the cover portion 105 is positioned above and each slot 93 of the shooter table 91 is closed. For example, when the rack 75 moves to the right in FIG. 17, for example, the pinion 73 of each roll brush 99 rotates 180 ° counterclockwise, and accordingly, the rotation shaft 61 of each roll brush 99 counteracts. It is in a state rotated 180 ° in the clockwise direction.

  As described above, with the simple structure of the rack 75 and the pinion 73, the free bear table and the brush table can be switched at high speed in a short time, and the switching response is high.

  The operation according to the above configuration will be described with reference to FIGS. In this figure, only the front side portion is shown, but the rear side also has the same operation.

  When the workpiece W is punched by the punching portion 9 or when the downward forming portion is laser-processed, the rotary shafts 61 of the plurality of roll brushes 99 are rotated 180 ° as shown in FIG. After rotating and positioning the brush portion 107 of each rotating shaft 61 upward, the shooter table 91 is lowered, and the pass line PL at the tip of the brush portion 107 inserted into each slot 93 of the shooter table 91 is used. This is a brush table state that supports the workpiece W. This is a so-called brush table mode.

  When normal laser processing is performed on the workpiece W with the laser processing head 25, the shooter table 91 is raised by the length of the brush portion 107 as shown in FIG. A large number of free bears 63 arranged on the upper surface between the slot portions 93 are positioned on the pass line PL, and the work W is supported by the large number of free bears 63. Further, as shown in FIG. 18C, the rotation shaft 61 of each roll brush 99 rotates 180 °. Actually, each roll brush 99 rotates in the same direction at the same time. However, in FIG. 18C, in order to easily understand the state of rotation, in FIG. Then, each slot 93 of the shooter table 91 is closed by the cover portion 105 of the rotating shaft 61 as in the state adjacent to the left. That is, the free bear table state is set as shown in FIG. This is a so-called free bear table mode. The above operation is automatically performed by the control device 55. When this cover part comes out on the upper surface, damage to the brush due to spatter and dross during normal laser processing is prevented.

  From the above, the shooter table 91 is lifted and lowered slightly by the length of the brush, and the roll portion 99 is normally closed by the cover portion 105 during laser processing only by rotating the roll brush 99 by 180 °. Then, when switching to the free bear table surface, or during punching or laser processing of the downward molding part, the brush part 107 is positioned above and can be switched to the brush table surface at a high speed, so that the switching response is improved. Thus, the processing efficiency is improved. As a result, there is no jamming or fluttering of the workpiece W, and the quality of the product is improved.
