[0009]

Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. FIG. 1 schematically shows a router machine. The router machine includes a motor 1 and a blade rotating unit 3 including a blade 2 attached to the motor 1, and a support member 4 for supporting the blade rotating unit 3. A Z-drive unit 5Z for moving the support member 4 in the vertical direction, an X-drive unit 5X for moving the Z-drive unit 5Z in a direction perpendicular to the paper surface (left-right direction),
A processing table 7 on which a game board 6 which is a gaming machine component is mounted;

The Z drive unit 5Z raises and lowers the blade 2 while rotating the blade 2 by driving the motor 1 to form a predetermined opening in a predetermined position of the game board 6 by cutting. Is what you do. The above game board 6
, A design drawing is drawn on the surface, and the game board 6 is mounted on the processing table 7 with the above-mentioned surface as the lower surface. The above Z
The support member 4 of the driving unit 5Z is provided with a cylindrical dust collecting cover attaching member 8, and the dust collecting cover attaching member 8 has a dust collecting cover 9 covering the periphery of the motor 1 and the blade 2. Installed. The dust collecting cover 9 includes a cylindrical dust collecting cover main body 10 and a brush 11 made of a synthetic resin having abrasion resistance provided at a lower opening end of the dust collecting cover main body 10. A dust collection duct 12 is attached to an upper open end of the dust collection cover attachment member 8. This dust collection duct 12 is provided with a dust collector 13 having a suction mechanism.
And sucks air from the gap between the brushes 11 and removes cuttings generated in the cutting process of the game board 6 and collected in the dust collecting cover 9 into the gap between the blade 2 and the dust collecting cover 9. The dust is sent to the dust collection duct 12 from the dust collection passage S formed by the above, and collected in the dust collector 13.

FIG. 2A is a view showing a cutting dust collecting portion of the router machine according to the first embodiment. The lower portion of the main body 10 of the dust collecting cover 9 is provided with a cylindrical elastic bellows structure. It is constituted by the elastic member 10z having the same. Reference numeral 14 denotes a lock lever for fixing the dust collecting cover 9 to the dust collecting cover mounting member 8. The expansion and contraction state of the expansion and contraction member 10z is extended by the weight of the expansion and contraction member 10z and the weight of the brush 11 until the cutting operation of the router machine is started, that is, until the blade 2 comes into contact with the upper surface 6a of the game board 6. is there. Immediately after the cutting tool 2 rotates and descends, and the cutting tool 2 comes into contact with the upper surface 6a of the game board 6 to start cutting, a gap d between the tip of the brush 11 and the upper surface 6a of the game board 6 is obtained. However, as shown in FIG.
The mounting position of the dust collecting cover 9 is set such that the cutting dust generated by the cutting is kept at a distance that does not scatter outside the dust collecting cover 9. Dust collection cover 9 immediately before the start of the cutting process
Is referred to as the initial position of the dust collection cover.

When the router machine starts cutting,
The support member 4 is lowered by the Z drive unit 5Z, and at the same time, the motor 1, the blade 2 and the dust collecting cover mounting member 8 are lowered, so that the tip of the blade 2 and the tip of the brush 11 are placed on the upper surface 6 of the game board 6.
a substantially simultaneously. When the blade 2 further descends, an upward reaction force from the game board 6 acts on the elastic member 10z of the dust collecting cover 9 via the brush 11, so that the elastic member 10z gradually contracts. As shown in FIG. 2B, when the tip of the blade 2 reaches the back surface 6 b of the game board 6, the extendable member 10 z moves by a distance D corresponding to the descending distance of the blade 2, that is, the thickness of the game board 6. Shrink. In addition, the maximum contraction width of the elastic member 10z is set to be larger than the above-mentioned dimension D in design, and the brush 11 has such rigidity that it does not deform even if the elastic member 10z is contracted more than the above-mentioned dimension D. It goes without saying that a thing is used. Therefore, the reaction force which the brush 11 receives from the game board 6 is absorbed by the expansion and contraction of the elastic member 10z, and the tip of the brush 11 is not deformed even if the cutting is repeatedly performed. Can always be kept at a position where cutting chips do not scatter outside the dust collecting cover 9. When the cutting of one opening is completed, the support member 4 is driven upward, the tip of the blade 2 rises above the upper surface 6a of the game board 6, and the dust collecting cover 9
Also returns to the initial position, and the elastic member 10z
Return to the length shown in FIG.

When an opening is formed in a portion near the peripheral portion of the game board 6, as shown in FIG. 3, the tip of one side of the brush 11 may hit the veneer holding clamp 15; The elastic member 10z of the cover 9 is
Since only the side is deformed so as to be greatly shrunk, the tip of the brush 11 contacting the clamp 15 is not deformed. Further, when the game board 6 is tilted to cut an opening at an angle to the game board 6, as shown in FIG.
The only difference is in the way in which the elastic member 10z shrinks in the vertical direction of the inclined surface.
Is in contact with the upper surface 6a of the dust collecting cover 9
There is no scattering outside.

As described above, in the first embodiment, since a part of the cylindrical dust collecting cover main body 10 is constituted by the telescopic member 10z which can expand and contract in the vertical direction, the cutting is started when the cutting of the router machine is started. The dust is kept at a position where it is not scattered outside the dust collecting cover 9, and at the time of cutting, the length of the elastic member 10z is reduced so that the brush 11
The tip of the brush 11 can be brought into contact with the upper surface 6a of the game board 6 without applying an extra load on the game board 6, so that cutting chips can be prevented from scattering outside the dust collecting cover 9. In addition,
Since the brush 11 having abrasion resistance is attached to the dust collection cover 9, the lower end of the dust collection cover can be prevented from sliding or being damaged.

In the first embodiment, a part of the dust collecting cover body 10 of the dust collecting cover 9 is constituted by the elastic member 10z having a bellows structure, but the entire dust collecting cover body 10 has the bellows structure. If it is constituted by an elastic member, the elastic member 1
0z can be expanded and contracted, so brush 1
1 can be further reduced. Alternatively, the same effect can be obtained even if the entirety of the dust collecting cover 9 or the dust collecting cover main body 10 is formed of an elastic member such as a rubber material. Also,
In the above example, the dust collection cover 9 is connected to the support member 4 of the Z drive unit 5Z.
The dust collecting cover 9 is attached to the dust collecting cover attaching member 8 provided in the above, but the dust collecting cover 9 may be directly attached to the supporting member 4. It is desirable that the tip position of the brush 11 immediately after the start of the cutting process is set to a position at which cutting chips generated by cutting the game board 6 do not scatter outside the dust collecting cover 9. Even if the dust collecting cover 9 is designed so that the elastic member 10z has a sufficient deformation range even when the dust collecting cover 9 is in contact with the surface 6a of the board 6, the load on the brush 11 is reduced by the elastic member 10z during cutting. No problem.

Although the brush 11 made of synthetic resin is attached to the lower end opening of the dust collecting cover 9 in the above example, an annular contact member made of a wear-resistant resin may be attached instead of the brush 11. . Although there is no suction gap like the brush 11 on the contact surface between the contact member and the surface 6a of the game board 6,
Since the processing surface (back side) of the game board 6 is made of veneer,
Air is sucked from microscopic irregularities on the surface of the veneer surface, which is the contact surface, so that cutting chips in the dust collecting cover 9 can be sucked. Further, if a plurality of slits extending in the radial direction are provided on the lower surface of the annular contact member to form an air suction passage, the dust collecting effect is further improved. The shape of the air inflow path provided in the annular contact member is not limited to the above-mentioned slit-shaped one. For example, even if a plurality of through holes are formed on the side surface of the contact member to provide an air flow path, the same applies. The effect of is obtained. In the above example, since the game board 6 is mounted on the worktable 7 with the surface (front surface) on which the design drawing of the game board 6 is drawn as the lower surface, the router processing is performed. An opening such as a hollow back digging or a through hole or the like can be formed on the surface (back surface) in one step. That is, it is possible to cut the back digging and the through hole without replacing the front and back of the game board 6 with the processing table 7.

Embodiment 2 FIG. 5A is a diagram illustrating a cutting dust collecting unit of the router machine according to the second embodiment.
A spring mounting projection 8a is provided at a position where the outer periphery of the dust collection cover mounting member 8 is equally divided, and a spring mounting projection 10 is provided at a position corresponding to the projection 8a of the dust collection cover main body 10.
The dust collecting cover 9 is attached to the dust collecting cover mounting member 8 by anchoring one end of the adjustment spring 16 to the projection 8a and the other end to the projection 10a. Further, a guide groove 8b is provided in the dust collecting cover mounting member 8, and the sliding member 1 which moves in the guide groove 8b is formed in the dust collecting cover main body 10.
0b, the dust collecting cover attaching member 8 and the dust collecting cover 9
And the so-called spline fitting, so that the dust collecting cover 9 can be moved up and down with respect to the dust collecting cover attaching member 8. FIG. 5B is a cross-sectional view showing the fitting portion. The sliding member 10b of the dust collecting cover main body 10 moves in the guide groove 8b of the dust collecting cover attaching member 8 in the front and back directions on the paper. . Further, in the figure, reference numeral S denotes a space formed between the motor 1 and the dust collecting cover 9 and the dust collecting cover attaching member 8 for sucking cutting chips.

The adjusting spring 16 is extended by its own weight of the dust collecting cover 9 including the brush 11 until the blade 2 contacts the upper surface 6a of the game board 6. Then, the cutting tool 2 rotates and descends, and the cutting tool 2 is moved to the upper surface 6 a of the game board 6.
Immediately after the cutting process is started in contact with the surface of the game board 6, the gap d between the tip of the brush 11 and the upper surface 6a of the game board 6 is changed as shown in FIG.
As shown in (a), the mounting position of the dust collecting cover 9 is set so that the cutting chips generated by cutting the game board 6 are kept at a distance that does not scatter outside the dust collecting cover 9. When the router machine starts cutting, the cutting tool 2 and the dust collecting cover attaching member 8 descend, and the tip of the cutting tool 2 and the tip of the brush 11 contact the upper surface 6a of the game board 6 almost simultaneously. When the blade 2 further descends, an upward reaction force from the game board 6 acts on the adjustment spring 16 via the brush 11, so that
The adjustment spring 16 gradually contracts, and when the tip of the blade 2 reaches the back surface 6b of the game board 6, as shown in FIG. Is reduced by a dimension D corresponding to the thickness of It is needless to say that the design is such that the adjustment spring 16 is extended beyond its natural length, and that the brush 11 has a rigidity enough to shrink the adjustment spring 16 to its natural length. Therefore, the reaction force that the brush 11 receives from the game board 6 is absorbed by the contraction of the adjustment spring 16, and the tip of the brush 11 is not deformed even when the cutting is repeatedly performed. The tip can always be kept at a position where cutting chips do not scatter outside the dust collecting cover 9.

As described above, in the second embodiment, the dust collecting cover 9 is connected to the dust collecting cover mounting member 8 by the adjusting spring 16 and a slide mechanism by spline fitting is provided to form the dust collecting cover 9. Since the dust collecting cover can be moved up and down with respect to the dust collecting cover mounting member 8, the lower end of the dust collecting cover 9 can be kept at a position where the cutting dust does not scatter outside the dust collecting cover 9 when the cutting operation of the router machine is started. At the same time, during cutting, the adjustment spring 16 is contracted, so that the brush 1
The front end of the dust collecting plate 1 is brought into contact with the upper surface 6a of the game board 6 so that the cutting chips are not scattered outside the dust collecting cover 9.

In the second embodiment, the dust collecting cover 9 and the dust collecting cover attaching member 8 are connected by the adjusting spring 16, and a slide mechanism by spline fitting is provided so that the dust collecting cover 9 is attached to the dust collecting cover. Although the adjusting spring 16 and the slide mechanism are omitted, the hook is provided at the upper end of the dust collecting cover main body 10 so that the dust collecting cover 9 is attached to the dust collecting cover mounting member 8. At the lowermost position, even if the hook has a simple structure in which the hook is engaged with the projection 8a of the dust collecting cover attaching member 8, the weight of the dust collecting cover 9 and the rigidity of the brush 11 can be appropriately designed. The dust collecting cover 9 is moved up and down by the reaction force from the game board 6, and the tip of the brush 11 is brought into contact with the upper surface 6a of the game board 6 without applying an extra load to the brush 11, so that cutting dust is removed. It can be prevented from being scattered to the outside. The dust collecting cover 9 and the dust collecting cover attaching member 8
If the above-mentioned slide mechanism is provided, it goes without saying that the vertical movement of the dust collecting cover 9 becomes even smoother.

Embodiment 3 In the second embodiment, as shown in FIG. 6, an actuator mounting member 8c is provided on the dust collecting cover mounting member 8, and a bolt-nut type actuator 17 for converting the rotation of a motor or the like into a linear motion is mounted on the actuator. The dust collecting cover 9 is attached to the member 8c, and the distal end of the expansion and contraction portion of the actuator 17 is fixed to the projection 10a of the dust collecting cover main body 10, and the actuator 17 is driven to move the dust collecting cover 9 up and down. It may be moved up and down. At this time, since the design condition of the adjustment spring 16 is different from the above example, it is only necessary to smooth the vertical movement of the dust collection cover 9. Therefore, in the third embodiment, instead of the adjustment spring 16, the minimum contraction length is changed. A simple guide spring 18 having a length longer than the natural length is used. When the actuator 17 is used as the vertical movement mechanism of the dust collection cover 9, the gap between the upper surface 6a of the game board 6 and the brush 11 can be kept constant during cutting. That is, immediately before the processing is started, the gap between the upper surface 6a of the game board 6 and the brush 11 is set to a distance d at which the cutting chips do not scatter outside the dust collecting cover 9, and the cutting tool 2 is lowered during the cutting processing. By controlling the driving of the actuator 17 so that the speed matches the rising speed of the tip of the actuator 17, the gap between the upper surface 6a of the game board 6 and the brush 11 can always be kept at the distance d. .

As described above, in the third embodiment,
By using the actuator 17 and moving the dust collecting cover 9 up and down with respect to the support member 4 so that the lowering speed of the blade 2 and the rising speed of the tip of the actuator 17 coincide, the upper surface 6a of the game board 6 and the brush 11 Can be maintained at a distance d at which cutting chips do not scatter outside the dust collecting cover 9. The tip of the brush 11 is located on the upper surface 6a of the game board 6.
The brush 11 does not have to be made of a material having abrasion resistance because it does not contact with the brush. Further, since air can always be sucked from the gap between the lower end of the dust collecting cover 9 and the upper surface 6a of the game board 6, the brush 11 of the dust collecting cover 9 can be omitted.

Embodiment 4 FIG. 7A is a diagram showing a cutting dust collecting unit of the router machine according to the fourth embodiment.
A plurality of strip-shaped dust collecting curtains 19 made of urethane rubber
Are attached to the lower portions of the plurality of brackets 20 with screws or the like, and the respective brackets 20 are attached using an adjustment spring 22 so as to be able to move up and down along a slide guide 21 provided at the lower portion of the dust collection cover main body 10. , The lower end of the dust collecting cover 9, that is, the strip-shaped dust collecting curtain 19.
Is configured to be movable up and down. FIG. 7 (b)
FIG. 7 (c) is a partial cross-sectional view showing a side surface of the mounting portion of the strip-shaped dust collecting curtain 19, showing an outline of the mounting portion. The bracket 20 includes a flat slide portion 20a and a stopper 20b attached to the upper portion of the slide portion 20a. The dust collection curtain 19 is screwed to a lower end of the slide portion 20a. Guide 21 and stopper 20
b is connected with the adjustment spring 22 so that the slide portion 20 a of the bracket 20 can be moved up and down along the slide guide 21. In addition, a suction prevention spring 23 is attached between the dust collecting curtain 19 and the bracket 20 so that the dust collecting curtain 19 is not drawn into the blade 2 side due to suction of cutting chips.

Until the blade 2 contacts the upper surface 6 a of the game board 6, the adjusting spring 22 is in the state of being most contracted by the weight of the bracket 20 and the dust collecting curtain 19. Then, immediately after the cutting tool 2 is rotated and descends, and the cutting tool 2 comes into contact with the upper surface 6a of the game board 6 to start cutting, the tip of the dust collecting curtain 19 and the upper surface 6a of the game board 6 are started.
The mounting position of the adjusting spring 22 or the dust collecting curtain 19 is set so that the gap between the adjusting spring 22 and the dust collecting curtain 19 is maintained so that the cutting dust generated by cutting the game board 6 does not scatter outside the dust collecting cover 9. When the router machine starts cutting,
The blade 2 and the dust collecting cover attaching member 8 are lowered, and the tip of the blade 2 and the tip of the dust collecting curtain 19 are connected to the upper surface 6a of the game board 6.
Contact almost simultaneously. When the blade 2 is further lowered, the bracket 20 is raised and the adjustment spring 22 is gradually extended, and when the tip of the blade 2 reaches the back surface 6b of the game board 6, the adjustment spring 22 is moved downward by the blade 2, that is, It extends by a dimension D corresponding to the thickness of the game board 6. By design,
It is needless to say that the adjusting spring 22 is used in a state of being contracted from its natural length, and the dust collecting curtain 19 has a rigidity enough to extend the adjusting spring 22 to its natural length. Therefore, the reaction force received by the dust collecting curtain 19 from the game board 6 is absorbed by the extension of the adjusting spring 22, and the dust collecting curtain 19 is repeatedly operated even when the cutting process is repeated.
The tip of the dust collecting cover 9 is not deformed, and the lower end of the dust collecting cover 9, that is, the tip of the dust collecting curtain 19 can be always kept at a position where the cutting dust does not scatter outside the dust collecting cover 9 during cutting.

Since the periphery of the cutting tool 2 is constituted by a plurality of independently rising and falling dust collecting curtains 19, even if the veneer holding clamp 15 as shown in FIG. Only the extension of the spring of the curtain increases, and only the dust collecting curtain at that location rises, and the other dust collecting curtains are in contact with the upper surface of the game board 6, so that cutting chips scatter outside the dust collecting cover 9. Nothing. Further, as shown in FIG. 4 described above, even when the game board 6 is inclined to process an opening or a through hole having an angle to the game board 6, each dust collecting curtain in the vertical direction of the inclined surface is also used. The only difference is the degree of contraction of the dust collecting curtain 19, and the tip end of each dust collecting curtain 19 is almost in contact with the upper surface 6a of the game board 6, so that cutting chips do not scatter outside the dust collecting cover 9. Further, since the dust collecting curtain 19 is made of urethane, which is an abrasion-resistant material, the lower end of the dust collecting cover 9 is less likely to slide or be damaged. Furthermore, if transparent or translucent urethane is used, it is possible to visually recognize the state of cutting chips in the dust collecting cover 9.

As described above, in the fourth embodiment, a plurality of strip-shaped dust collecting curtains 19 made of urethane rubber are mounted on the dust collecting cover 9 so as to be vertically movable. Also, in the case where the gaming board 6 is tilted and the above-mentioned gaming board 6 is formed with an opening having an angle, only the extension of the spring of the dust collecting curtain at the position becomes large, so that the lower end of the dust collecting curtain is always kept. Since it is in contact with the upper surface of the game board 6, cutting chips do not scatter outside the dust collecting cover 9.

In the first to fourth embodiments, the Z driving unit 5Z
The dust collector provided in the router machine configured to raise and lower the blade 2 by moving the support member 4 that supports the blade rotating unit 3 up and down is described. Is configured to be able to move up and down with respect to the support member 4. Therefore, even if the game board 6 is raised without the support member 4 being lowered (the blade 2 is not lowered), the dust collection cover 9 and the game The relative positional relationship of the board 6 does not change. Therefore, the support table 4 does not move up and down, and
The dust collectors of Embodiments 1 to 4 can be applied to a router processing machine configured to move in the vertical direction. In the above example, the cutting of the game board 6 has been described. However, in the cutting of other game machine components such as the inner frame and the outer frame, cutting chips generated during the processing are scattered outside the dust collecting cover. Needless to say, it can be avoided.

As described above, in the dust collecting apparatus for a router machine according to the first aspect, the lower end of the dust collecting cover attached so as to cover the periphery of the blade is brought into contact with the upper surface of the game board. Alternatively, the lower end of the dust collecting cover is maintained so that a gap between the lower end of the dust collecting cover and the gaming machine component is maintained at a distance such that cutting chips generated during processing of the gaming machine component do not scatter outside the dust collecting cover. Can be moved up and down with respect to the supporting member that supports the blade rotating portion, so that the cutting chips can be prevented from scattering outside the dust collecting cover during cutting by the router machine.
