Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw position display device for a traveling circular saw that displays the protruding position of a circular saw on a table.

[0002]

2. Description of the Related Art As a processing machine for cutting large plates, there are running circular saws called running saws and panel saws. In this machine, as shown in the explanatory view shown in FIG. 5, the circular saw S first projects in the middle of the traveling stroke, and then travels toward one end (lower end) of the stroke to cut the workpiece W. To do. After the processing, the circular saw S is returned to the midway position of the traveling stroke and stands by for the next cutting processing.

The protruding position of the circular saw S is artificially set by the stroke adjusting means, and the processed material W
It is adjusted appropriately according to the cutting length. However,
At this time, the circular saw S is in the standby position and is on the back surface of the table T, and is not visible, which is inconvenient. Therefore, a "saw position display device for a traveling circular saw machine" according to Japanese Utility Model Laid-Open No. 58-50902 has been conventionally proposed.

[0004]

This conventional display device has a display piece 5 illuminated by a light source 50 as shown in FIG.
1 is configured to face the saw traveling slit 52. However, the slit 52 for saw running has a very small width dimension, so that the size of the display piece 51 is limited, and there is a drawback that a clear display cannot be performed. Particularly in this type of machine, the display piece 51 is slanted from the working position.
Since there is no choice but to look at it, there is a problem that the visibility is further reduced.

The present invention has been made in view of the above-mentioned problems of the prior art. By devising the structure of the display member, it is possible to provide a saw position display device for a traveling circular saw that has good visibility. It is what

[0006]

In order to achieve the above object, a saw position display device according to the present invention is constructed as follows. In other words, the gist of this is to provide a light emitting body that illuminates the display light on the side of the saw base with a circular saw, and to connect the front side and the back side to the table side at a position away from the saw traveling slit. The through-hole is provided, and the translucent display member that receives the irradiation light of the light-emitting body is arranged in the through-hole.

The invention of claim 2 is characterized in that, in the saw position display device of claim 1, the through hole is a round hole, and the display member is a cylindrical body provided by being fitted in the round hole. .

[0008]

The display member receiving the irradiation light of the light emitter displays the display light on the front side of the table. The operator can confirm the saw position by the display light. Since the above-mentioned display member is located outside the saw traveling slit, it is not limited in size or the like.

According to the second aspect of the invention, the through hole can be easily machined by drilling, and the cylindrical body is simply fitted and fixed to the through hole, which facilitates the manufacture. . Further, since no long groove is provided, the strength of the table is not lowered.

Reference numeral 27 is a pressing plate disposed on the mounting frame 24 by the link arms 28, 28 is a pneumatic cylinder connected to the link arm 28 so as to operate the pressing plate 27 in the front-back direction.

In addition, in one embodiment of the present invention, in addition to the above-mentioned structure, the following main structure is provided. That is, in FIGS. 3 and 4, reference numeral 30 denotes a light-emitting body mounted on the side portion of the dust collecting cover 18 via a mounting stay 31. The light-emitting body 30 is, for example, a light-emitting diode (high brightness LED). The luminous body 30 emits the display light toward a lateral position that is off the saw traveling slit 5.

Through holes 32 and 32 are provided at intervals in the vertical direction of the blade plate 4 (50 mm pitch as an example) corresponding to the irradiation position of the display light. The through holes 32 and 32 are round holes formed by drilling. (The diameter is 10 mm as an example).

The structure of the saw position display device according to one embodiment is as described above, and when a power switch (not shown) is turned on for cutting the workpiece W, power is supplied to the light emitter 30 to emit light. To do. Arranged display members 33, 33
Corresponding one of them receives the irradiation light and clearly shows the display light on the front side of the table 3 by light transmission. Therefore, the operator can confirm the position of the circular saw 16 by this display light.

Since the display members 33, 33 are arranged at intervals apart from the saw traveling slit 5 in that direction, a clear display can be made regardless of the position of the saw base B. The light emitting body 30 and the display members 33, 33
Since the display light can be emitted over the two objects by taking a distance from, there is no display problem even when they are arranged at intervals.

In one embodiment, since the through hole 32 is formed by drilling, it is easy to machine. On the other hand, since the display member 33 has a cylindrical shape, it is easy to manufacture and can be manufactured at low cost. . Further, since the strength of the blade plate 4 is not reduced, there is no warp or distortion, and the accuracy of the cutting process can be maintained.

In the above embodiment, the light emitting body 30 and the display member 33 are provided only on one side of the saw traveling slit 5, but the visibility can be further improved by providing these on both sides. Further, it goes without saying that a plurality of light emitting bodies 30 may be attached within the projecting range of the circular saw.

In the embodiment, the display member 33 and the through hole 32 for mounting the display member 33 have a round cross section. However, as long as the strength of the table 3 (blade plate 4) is not reduced, it is oval or long. It can be changed to a square shape. Although the light emitting diode (high brightness LED) is used as the light emitting body 30 in consideration of durability, brightness, etc., it may be changed to a filament light bulb, a laser beam, or the like.
