Description

The present invention cuts or cuts various materials to be cut such as a synthetic resin plate, a rubber plate, and a paperboard set on a table by a cutting member moving in the two-dimensional direction of the XY axis into a desired shape More particularly, the present invention relates to an XY plane cutting apparatus having a function of changing a support mode of a material to be cut in accordance with at least two types of cutting means mounted as a cutting mechanism and a laser beam output means.
About.

  As an XY plane cutting device, a cutting device using a cutting tool such as an end mill or a cutting blade as a cutting mechanism, and a cutting device using a laser beam output means as a cutting mechanism are known. Among them, as a cutting apparatus using laser light output means, for example, as shown in Patent Document 1, a pair of gantry stages attached in parallel to the left and right sides of a cutting table that holds a glass substrate to be cut in a horizontal state In the upper part of the gantry structure, the gantry structure is mounted perpendicularly to the gantry stage so as to be capable of moving forward and backward along the gantry stage, and a laser fixedly provided at the upper part of both ends of the gantry structure. A laser irradiation head, which is attached to both ends of the oscillation unit and the gantry structure so as to be movable left and right along the gantry structure and irradiates the glass substrate with the laser oscillated from the laser oscillation unit. The glass substrate is cut while moving in the XY axis direction.

  In the glass substrate laser cutting apparatus, since the laser light output means is employed as the glass substrate cutting mechanism, the cutting portion of the glass substrate as the material to be cut is not in contact with the table surface of the cutting table. Therefore, a cutting table is provided with a conveyor, and the cutting portion of the glass substrate is supported by the conveyor so as not to contact the table surface.

On the other hand, in a cutting device using a cutting tool or cutting blade such as an end mill as a cutting member, in order to cut while moving in the XY axis direction while pressing the cutting tool or cutting blade against the material to be cut, It is necessary to support the material to be cut in contact with the table surface of the cutting table.

As described above, since the support mode of the material to be cut with respect to the cutting table is different depending on the cutting member, the material to be cut cannot be cut with different cutting members with one cutting device. That is, in a cutting apparatus provided with laser light output means as a cutting member, a cutting table that supports the object to be cut in a non-contact state, and a cutting apparatus provided with rotary cutting means and a cutting blade as cutting members. In this case, it is necessary to provide a cutting table for supporting the material to be cut in a contact state, and a single cutting table cannot be cut by switching different cutting members.

Any of a belt mechanism or the like may be used.

  A guide rail 11b that extends horizontally in the X-axis direction is fixed to a traveling frame 11 that is positioned above a table plate 29 described later, and the traveling body 17 moves in the X-axis direction on the guide rail 11b. It is supported by. The traveling frame 11 has an axis in the X-axis direction, and a feed screw 19 with which a nut portion 17 a provided on the traveling body 17 is engaged is rotatably supported. An X-axis electric motor 21 constituting a second moving member such as a servomotor is drivingly connected to the section.

The traveling body 17 is reciprocated in the X-axis direction with the drive control of the X-axis electric motor 21. Note that the X-axis moving mechanism of the traveling body 17 may be any of the above-described belt mechanism, rack and pinion mechanism, and the like.

  A cutting means 23 and a laser beam output means 25 are attached to the traveling body 11 at a required interval in the X-axis direction or the Y-axis direction (in the illustrated example, the Y-axis direction). The cutting means 23 includes a cutting blade 23a attached to a rod of a vertically moving member 27 such as an air cylinder that moves up and down with a predetermined stroke, and an ultrasonic oscillation means (not shown) for ultrasonically vibrating the cutting blade 23a. Consists of. Although the cutting means 23 is a cutting blade 23a that vibrates ultrasonically, it may be a rotary cutting member such as an end mill, or a rotary cutting means may be provided separately from the cutting means 23, and the laser beam output. It is good also as a structure provided with three types of cutting mechanisms with the means 25. FIG.

The vertical moving member 27 is moved down to a position where the blade edge comes into contact with the upper surface of the table plate 29 when cutting the plate material 33 as the material to be cut placed on the table plate 29. The vertical movement member 27 has an axial line in the vertical direction, and is connected to a feed screw with which a nut portion provided in the cutting means 23 is meshed, and an electric motor such as a servo motor so as to be numerically controllable. A feed screw mechanism constituted by a motor may be used to numerically control the processing amount of the cutting blade 23a. Further, as the plate material 33, various sheet materials such as a synthetic resin plate, a laminated plate, a rubber plate, and a paperboard are used.

The laser beam output means 25 is composed of a laser oscillator such as a YAG laser oscillator, an excimer laser oscillator, a CO2 laser oscillator, and a fiber laser, and an optical lens (none of which are shown), and a table on a table plate 29 as will be described later. It is set so that the laser beam converges on the plate material 29 lifted to a predetermined height by the support shaft 31 as a support member with respect to the surface. In the laser light output means 25, the convergence distance can be varied by changing the focal length of the optical lens. However, as with the cutting means 23, the convergence distance can be varied with respect to the plate member 33 by being mounted on the lifting mechanism. It may be.

  A plurality of (in this example, four, but not limited to) a plurality of table plates 29 are attached to the upper surface of the main body frame 3 so as to be flush with each other. It has been. Each table plate 29 is formed with a plurality of suction holes 29a and a predetermined number (in this example, nine per hole) of through holes 29b are provided at predetermined intervals in the XY axis direction. Formed after. In addition, a shaft support member 35 having a shaft support hole 35a communicating with the upper space portion of the main body frame 3 is attached to the partition plate 5 facing each through hole 29b.

  On the lower surface of the partition plate 5, a number of support shaft lifting means corresponding to the number of support shafts 31 (in this example, three support shafts are lifted and lowered by one support shaft lifting means). 37 is provided. Each support shaft elevating means 37 has a pair of guide shafts 39 each having an axis in the vertical direction and having an upper end fixed to the lower surface of the partition plate 5 at a predetermined interval, and fixed to the lower ends of each guide shaft 39. An air cylinder, an electromagnetic solenoid or the like fixed to the intermediate portion in the longitudinal direction of the mounting plate 41, and an elevating member 43 having a predetermined operating stroke, an axis in the vertical direction, and a pair of guide shafts 39 in the vertical direction The lower part is fixed to the elevating plate 45 supported so as to be slidable, and is constituted by three support shafts 31 that can be inserted into the shaft support hole 35a of the shaft support member 35 in an airtight manner. The upper end portion of each support shaft 31 is formed in a small diameter.

  A plurality of suction port portions 47 communicating with the upper space portion are attached to the partition plate 5 corresponding to the space between the support shaft lifting and lowering means 37 at appropriate intervals, and each suction port portion 47 is, for example, a negative such as a blower. The pressure generating means 49 is connected via a hose (not shown). In the upper space of the main body frame 3, negative pressure is formed as the negative pressure generating means 49 is driven.

Next, the support changing operation of the plate member 33 according to the present embodiment will be described.
First, the cutting action of the plate material 33 by the cutting blade 23a will be described. When the plate material 33 is cut by the cutting blade 23a, the plate material 33 set on the table plate 29 is not displaced due to the cutting resistance of the cutting blade 23a. It is necessary to fix to.

  In this case, each support shaft raising / lowering means 37 is kept in an inoperative state, and the movement state of each support shaft 31 with respect to the lower position is maintained. At this time, the upper end of each support shaft 31 is located below the lower surface of the table plate 29 and is kept in a non-projecting state from the upper surface of the table plate 29. (See Figure 5)

Also, when the plate member 33 is set on the table plate 29 in a state where the negative pressure generating means 49 is driven in the above state and the negative pressure is formed in the upper space portion of the main body frame 3, the plate member 33 receives a large number of suctions. A negative pressure is sucked through the hole 29a and fixed on the table plate 29 in a close contact state.

In the above state, the Y-axis electric motor 13 is driven and controlled based on the cutting position data previously stored in the storage means of the controller to move the traveling frame 11 in the Y-axis direction and the X-axis electric motor 21 is driven and controlled. After the traveling body 17 is moved in the X-axis direction and the cutting means 23 is positioned at a predetermined cutting start position, the vertical movement member 27 is operated at the cutting start position, and the cutting blade 23a is moved to the table. In the state where it is lowered to the position where it abuts on the upper surface of the plate 29, the traveling frame 11 and the traveling body 17 are controlled to move, and the plate material 33 is cut into a desired shape. (See Figure 6)

At this time, since the plate member 33 set on the table plate 29 is adsorbed and fixed on the table plate 29 by the negative pressure described above, it is prevented from being displaced due to the cutting resistance by the moving cutting blade 23a. ing. Moreover, since the cutting blade 23a is minutely vibrated by the ultrasonic wave oscillating means, the cutting resistance of the plate material 33 can be reduced.

When the cutting work of the plate member 33 by the cutting blade 23a is completed, the driving of the negative pressure generating means 49 is stopped to release the negative pressure adsorption of the plate member 33 by the table plate 29, and the vertical movement member 27 is moved back and cut. After the blade 23a is lifted and separated from the table plate 29, the traveling frame 11 and the traveling body 17 are controlled to move back to the original position and wait.

Next, the cutting action of the plate material 33 by the laser beam output means 25 will be described. When the plate material 33 is cut by the laser beam, the cutting portion of the plate material 33 is brought into a non-contact state with respect to the table surface of the table plate 29. There is a need.

Therefore, when the cutting mode is switched to the laser beam cutting mode, each lifting member 43 is actuated to move the respective support shafts 31 upward, and the upper portion through which the through hole 29b is inserted has a predetermined height at the table plate 29. Protrude from. Then, the plate member 33 to be cut is set on the upper end of each support shaft 31 protruding upward from the table plate 29 at a predetermined height, thereby bringing the plate member 33 into a non-contact state with respect to the table plate 29. (See Figure 7)

As a setting mode of the plate member 33, the plate member 33 is set at a predetermined position on the table plate 29 in a state in which each support shaft 31 is lowered, and then the respective lift shafts 43 are operated to move the respective support shafts 31 upward. Alternatively, the plate 33 set on the table plate 29 may be lifted to a required height.

After the above operation, the traveling frame 11 and the traveling body 17 are controlled to move and the laser beam output means 25 is positioned at a predetermined cutting start position, and then the traveling frame is output while outputting the laser beam to the plate member 33. 11 and the traveling body 17 are controlled to cut the plate 33 into a desired shape. (See Figure 8)

When the plate material 33 is cut by the laser beam output means 25, the laser beam output from the laser beam output means 25 is set to converge on the plate material 29. Thus, there is no need to raise and lower the laser beam output means 25. Further, when the plate material 33 is cut by the laser beam from the laser beam output unit 25, the cutting position data stored in the storage unit of the controller is used as the Y axis direction or the X axis direction of the cutting unit 23 and the laser beam output unit 25. The travel frame 11 and the travel body 17 may be moved and controlled by driving the Y-axis electric motor 13 and the X-axis electric motor 21 based on the corrected cutting position data.

In this embodiment, one XY plane cutting device 1 can change the support mode of the plate material 33 with respect to the table plate 29 corresponding to the cutting mode, and can improve cutting efficiency and cutting cost. Can be reduced.
