JP 2006-130573 A

However, in the cutting machine disclosed in Patent Document 1, there is a possibility that the sheet 2 on the base 10 is displaced due to the wind pressure when the fixing plate 20 is pushed down.
Further, once the sheet 2 is fixed, the cutting position cannot be changed unless the handle 70 is operated again to release the pressing of the fixing plate 20, so that it is difficult to finely adjust the cutting position.
Accordingly, an object of the present invention is to provide a cutting machine that prevents positional displacement due to wind pressure when the fixing plate 20 is pushed down and that allows easy adjustment of the cutting position.

In order to solve the above problems, the present invention provides a base (10) on which a sheet (2) is placed, and a fixing plate (20) for pressing the placed sheet (2) onto the base (10). And a slider (30) fitted with a cutting blade (3), and the slider (30) is slidably attached, and the fixing plate (20) is attached to the lower end, and is separated from the base (10) by 2 mm to 4 mm. A rail (40) disposed at a position where it can be moved up and down , and the rail (40) by pushing down the rail (40) at a height of 0.2 mm to 0.5 mm above the base (10). A cutting member (1) configured to include a locking member (60) for fixing the slider (30) , wherein the slider (30) is engaged with the rail (40) and slides. And urged upward with respect to the base (31) And a main body portion (33) for holding the cutting blade (3) in a state, and the cutting blade (3) is projected by pushing down the main body portion (33), and the fixing plate ( 60) is configured to be pressed onto the base (10) .

The rail is disposed at a position separated from the base via link bars rotatably provided at both ends, and is urged to a position 2 mm to 4 mm away from the base by an elastic member. The rails positioned 0.2 mm to 0.5 mm above the base by the lock member are lowered by pressing down the main body of the slider, and the fixing plate presses the base evenly. It may be what was done.
Further, the lock member includes a first fixing means for fixing the rail at a height of 0.2 mm to 0.5 mm above the base when the slider is positioned at a starting end of the rail; And a second fixing means that is operated by movement to press-contact the fixing plate on the base.
In this case, the lock member is an elastically deformable cross-sectionally U-shaped member fixed rotatably at the lower end portion, and provided with the first fixing means that pushes down the rail from above at the top, The second locking means that is operated by the movement of the slider via a projecting lock operation portion provided on the bottom surface of the slider may be provided at the lower end.

In the cutting machine according to the present invention, the rail is fixed at a height that allows a fine adjustment of the seat position to be formed between the base and the base by pressing down the rail and fixing it with a lock member. Therefore, after the rough alignment and the lock member are operated, a more precise alignment can be performed using a slight gap with the base.
This makes it possible to correct the displacement of the sheet due to the wind pressure when the fixing plate is pushed down on the substrate by precise alignment performed after the operation of the lock member.
At this time , the cutting blade of the slider is urged upward by the elastic member, and if the manual pressure is applied to the slider, the cutting blade can be lowered to the position of the sheet. It is also possible to cut in the released state.

When the lock member is released, the cutting machine according to claim 2 is arranged at a position separated from the base via the link bar in a state where the rail to which the fixing plate is attached is urged upward by the elastic member. Therefore, by pressing the rail, the sheet can be pressed on the base by the fixing plate.

If locked operation, while performing position adjustment of the seat through a slight gap between the fixed plate and the foundation, it is possible to make fine adjustment of the position in the middle of cutting. At this time, only when the slider is pressed, the pressing force acts on the rail in the vertical direction, and the rail is further lowered while maintaining the horizontal state by the link bar. Therefore, the sheet is firmly fixed on the base by the fixing plate. It becomes a state.
Further, since the vertical force applied to the rail is uniformly applied in the horizontal direction, the pressure when the slider is pushed down acts on only a part of the rail, thereby preventing the seat from being displaced. .

In the cutting machine according to claim 3 and claim 4, when the slider is positioned at the start end of the rail, first, the rail is fixed at a height of 0.2 mm to 0.5 mm above the base. Since the fixed plate is pressed onto the substrate by the movement of the slider, rough alignment and precise alignment can be performed in stages. Further , the fixed plate can be pressed onto the substrate by moving the slider.

A guide portion 46 composed of two ribs is provided on the top surface portion inside the arm member 42, and the parallel member 44 is accommodated in the guide portion 46. Thereby, the rotational movement of the link bar 43 is converted into the vertical movement of the parallel member 44, and the rail 40 supported by the parallel member 44 is raised and lowered while maintaining the horizontal state (see FIG. 5).

A support body 50 is fitted into a portion to which the link bar 43 of the bottom portion 14 of the base 10 is attached.
This support body 50 is a member for supporting the rail 40 in a state of being biased upward, and a cylindrical spring mounting portion 52 is provided on the inner top surface portion, and a spring is interposed between the bottom portion 14. ing. In the initial state, the urging force of the spring causes the rail 40 to be positioned at a height of about 2 mm to 4 mm (preferably 2.5 mm to 3 mm) away from the surface of the base 10.

A fixing plate 20 for fixing a sheet placed on the base 10 is attached to the lower end of the rail 40.
The fixing plate 20 is made of a transparent synthetic resin member, and as shown in FIG. 3, only the edge 21 on the side to be cut is colored with an opaque color. The slider 30, since the cutting blade 3 to the end edge 21 of the fixed plate 20 is attached to the rail 40 so as to be positioned, colored edge 21 coincides with the cutting line, the cutting position on the sheet It can be made easier to confirm.

Next, the configuration of the slider 30 slidably attached to the rail 40 will be described with reference to FIG.
The slider 30 includes a base portion 31 that is slidably engaged with the rail 40, a main body portion 33 that rotatably accommodates the cutting blade 3 on the side wall surface 32, and the cutting blade 3 that covers the side wall surface 32. The cover part 34 includes a cover part 34 and a dial-like attachment / detachment operation part 35 for detachably fixing the cover part 34 to the body part 33.

The main body portion 33 to which the cutting blade 3 is attached is urged upward by an elastic member 36 interposed between the base portion 31 and the main body portion 33.
A disc-shaped cutting blade 3 is accommodated on the side wall surface 32 of the main body 33 in a state where the blade surface is in contact with the wall surface . The side wall surface 32 is provided on the side of the side member on which a concave accommodating portion that accommodates the cutting blade 3 and a locked portion that is engaged with a locking portion that is provided on the rotation shaft of the attaching / detaching operation portion 35. Although configured as a wall surface, a color different from that of the main body portion 33 and the lid portion 34 is given to the side surface member.

In this way, by configuring the side member with a member having a color different from that of the other part, a color different from that of the other part is applied to the part where the cutting edge of the cutting blade 3 is extended. The position can be easily recognized, and the cutting position can be easily confirmed.
Since the side wall surface 32 in which the cutting blade 3 is accommodated is covered with the lid portion 34, a colored line appears at a position corresponding to the cutting line on the outer peripheral surface of the slider 30.
A through hole is provided in the center of the lid portion 34, and the rotation shaft of the attachment / detachment operation unit 35 is inserted into the through hole. A fitting portion that can be fitted to the side member is provided at the tip of the rotating shaft, and the lid 34 can be attached to and detached from the main body via the side member by rotating the dial-like attachment / detachment operation portion. Can be done.

And appear different colors lines with the other sites on the position of the cutting blade 3, the side edges of the site is cut side of the fixing plate 20, since the slider 30 is disposed so as to be positioned, fixed plate It becomes easy to recognize that it cuts along 20 side edges.
Thereby, the cutting mistake by misidentifying the position of the cutting blade 3 can be prevented. In particular, by coloring the edge 21 of the transparent fixing plate 20 with the same color as the color of the side wall surface 32 of the slider 30, the cutting line can be easily understood intuitively.

As shown in FIG. 6, a lock member 60 for pushing down the rail 40 and fixing the height of the rail 40 is provided at one end of the rail 40.
As shown in FIG. 7, the lock member 60 is a U-shaped member that can be elastically deformed, and has a lock portion 61 that pushes down the rail 40 from above and fixes it at a predetermined height. The lower end portion is fixed to the support member 50 so as to be rotatable (see FIG. 8).

The lock portion 61 of the lock member 60 has a shape that can be engaged with the engaging portion at the upper end of the support body 50 by being elastically deformed, and a lock operation portion 63 provided in a protruding shape at the upper end portion. By operating in the locking direction, the lock portion 61 is locked to the locked portion of the rail, and the rail 40 is pushed down against the urging force of the elastic member provided inside the support body 50.
Thereby, as shown in FIG. 7B, the fixing plate 20 fixed to the rail 40 is fixed on the base 10.

More specifically, the lock member 60 has a structure that is locked in two stages of a fine adjustment position and a fixed position. That is, as shown in FIG. 9, in addition to the lock portion 61 fixed by the lock operation, a second lock portion 69 that is locked by the movement of the slider 30 is provided. For example, by providing a projecting lock operation part 39 on the bottom surface of the slider 30, the second lock part 69 is operated by the movement of the slider 30 so that the rail 40 can be further pushed downward. May be .

With this configuration, the slider 30 is locked in a state where the slider 30 is positioned at the starting end portion of the rail 40, so that the rail 40 is first lifted 0.2 mm to 0.5 mm above the base 10 by the lock portion 61. Further, the second lock portion 69 is operated by the movement of the slider 30 so that the fixing plate 20 can be firmly pressed onto the base 10.

The usage state of the cutting machine having the above-described configuration will be described with reference to FIGS.
First, the sheet 2 is inserted between the base 10 and the fixed plate 20 with the lock member 60 released. At this time, since the rail 40 to which the fixing plate 20 is attached is located at a height slightly away from the base 10, alignment is performed while inserting the sheet 40 into the gap.

Then, the lock operation shown in FIG. As a result, the rail 40 is pushed down against the urging force of the support 50. At this time, as shown in FIG. 5 (b), the rail 40 is lowered while maintaining a horizontal state by the link mechanism between the base 10.
By this link mechanism, a downward pressing force is applied uniformly to the fixing plate 20 attached to the rail 40 in the horizontal direction, so that the sheet on the substrate 10 can be fixed with a uniform pressing force.

In this way, with the sheet 2 fixed, as shown in FIG. 7C, the hand pressure F is applied to the slider 30 and moved in the cutting direction. As shown in FIG. 3B, the spring 36 interposed between the base portion 31 of the slider 30 and the main body portion 33 contracts by this pressing force, and the cutting blade 3 attached to the main body portion 33. Descends to the position of the base 10 (see FIG. 10).
As a result, the seat 2 is not cut during the locking operation, so that there is no inconvenience that the slider 3 must always be positioned at the starting end (initial position) of the rail.

Further, since the gap between the base 10 and the fixed plate 20 is set to 2 mm to 4 mm (preferably 2.5 mm to 3 mm), the seat 2 is caused by the wind pressure when the rail 40 is pushed down by the locking operation. Misalignment can be prevented, and highly accurate alignment can be performed.
In particular, the spring between the base 31 and the main body 33 of the slider 30 is designed so that the main body 33 can be lowered to a position where it can be cut by the operation of the slider 30 by manual pressure. It is also possible to perform a cutting operation without performing the operation.

As described above, the accuracy of alignment can be increased and cutting can be easily performed, so that it is possible to use in accordance with various usage situations, and versatility as a cutting machine is improved.
In the slider 30 of the present embodiment, the outer peripheral edge of the side wall surface 32 in which the cutting blade 3 is accommodated is colored with a color different from the others, and the outer peripheral edge of the side wall surface 32 is positioned on the side edge of the fixed plate 20. However, the outer peripheral edge of the side wall surface may be configured in a different cross-sectional shape, and the outer peripheral edge of the side wall surface may be configured with a tactile member different from the others.
Moreover, the fixing plate does not necessarily need to be comprised with a transparent member, and does not need to color a side edge part.
