DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle cutting ruler for a circular sawing machine suitable for diagonally cutting a large plate.

[0002]

2. Description of the Related Art A running circular saw called a running saw or a panel saw is used to cut a large plate material such as an inner wall panel and an outer wall panel for a building into a predetermined size and shape. Parallel or right angle cutting is performed to finish the work material into, for example, a rectangle, and oblique cutting (angle cutting) is performed to finish the work material into, for example, a triangular shape.

[0003] For the purpose of performing such a cutting process, there has been proposed a processing machine entitled "Free cutting device for plates" in Japanese Utility Model Publication No. 52-316. This processing machine is a panel saw having a substantially vertical table surface as shown in FIG. 8, and applies a circular saw unit 53 to a processing material W supplied on a horizontal ruler plate 52 provided below the table surface 51 in the vertical direction. The above-mentioned parallel or right angle cutting is performed by traveling.

In a conventional processing machine, as shown in FIG. 9, an angle ruler 54 on a horizontal ruler plate 52 whose inclination can be adjusted.
Can be disposed, and the workpiece W
Is set, the oblique cutting (angle cutting) processing can be performed. In FIG. 9, the circular saw unit 53 is used.
Is turned to set the circular saw (not shown) in the horizontal direction, and the workpiece W is horizontally moved along with the angle ruler 54 to perform the cutting process. Angle cutting can also be performed by turning the circular saw upright and traveling up and down.

[0005]

In order to perform angle cutting in a conventional processing machine, an angle ruler 54 is set to a predetermined inclination angle as a work procedure, and then a workpiece W is supplied onto the ruler. Subsequently, the workpiece W is horizontally moved together with the angle ruler 54 to perform cutting. Here, the adjustment of the right angle ruler 54 is performed first because the inclination adjustment is difficult due to the weight of the work material W after the work material W is set. Further, even when processing is performed by the second method, it is the same in that the inclination of the right angle ruler 54 is adjusted first.

For this reason, conventionally, the work material W must be supplied so as to be dropped from a considerably high position.
It took a lot of effort. Further, since the work material W is supplied in an oblique posture, the balance is poor, and there is a case where the work material W may be damaged due to overturning and the like.

In the conventional angle ruler, a rotation center position P of an L-shaped ruler surface 55 and a workpiece W serving as a dimension setting reference are set.
Are different from each other, so that the above-mentioned dimension reference position shifts in the left-right and up-down directions with the change of the angle. Therefore, each time the angle is changed, the cutting position must be corrected by measuring the actual object.

Further, as described above, the workpiece W supplied in an oblique posture is unstable, and if not supported artificially, the side end surface of the workpiece W rises from the ruler surface 55, which is high. Cutting precision cannot be expected. This problem in accuracy can be solved by increasing the length of the ruler surface 55. However, in this case, the problem in the supply of the work material W becomes more prominent and is inappropriate.

The present invention has been made in view of the above-mentioned problems of the prior art, and facilitates the cutting work.
An object of the present invention is to provide an angle cutting ruler for a running circular saw that can be performed with high accuracy.

[0010]

Means for Solving the Problems To achieve the above object, an angle cutting ruler for a traveling circular saw according to the present invention is constructed as follows.

In other words, the gist of the invention is that a plate-shaped workpiece supplied to a table is pressed and clamped on a table surface by a pressing means, and the workpiece is cut by a traveling circular saw. On the board,
A moving body that is controlled to move in a direction perpendicular to the traveling direction of the circle is provided. The moving body has a contact surface that comes into contact with two adjacent side end surfaces of the work material, and the intersection of the side end surfaces is provided. An angle ruler for rotating around a line portion is provided, and the angle ruler is provided with a rotation driving means for rotation control.

Further, the angle cutting ruler for a running circular sawing machine according to the present invention is characterized in that, in claim 2, the angle ruler means is provided with clamp gripping means for clamping and gripping a corner portion of the workpiece. .

According to a third aspect of the present invention, there is provided an angle cutting ruler for a traveling circular sawing machine, wherein the contact surface of the angle ruler comprises a long side contact surface and a short side contact surface. The gist is that it is constituted by a right angle ruler.

In the angle cutting ruler device having the above structure, the angle ruler is first set to a position where the work material can be easily received, and after the work material is supplied, the angle ruler is controlled to rotate to set the oblique cutting position. I do. And in the angle setting state,
The cutting position of the work material is determined by controlling and moving the circular saw in a direction perpendicular to the traveling direction.

Since the center of rotation of the angle ruler coincides with the corner of the processing material as the processing reference point, the cutting dimension reference position does not change even when the angle of the processing material changes. is there.

In the case of the second aspect, the work material can be firmly held against the contact surface, and the turning operation or the moving operation can be performed in this state.

According to the third aspect of the present invention, the work material can be transported with the table side facing the short-sided contact surface largely open.

An angle ruler means E is provided at the tip of the mounting frame 39. It comprises a right angle ruler 40 that rotates around a vertical axis, and rotation driving means 41 that controls the rotation of the right angle ruler 40. As shown in FIG. 6, the right angle ruler 40 has a long side contact surface a and a short side contact surface b which contact two adjacent side end surfaces a and b of the workpiece W at a right angle.

The clamp gripping means F is a fixed shape provided corresponding to a corner of the workpiece W. And a movable upper pressing piece 45. The upper holding piece 45 is vertically moved by a pneumatic cylinder 46, and the workpiece W
Is clamped. The lower receiving piece 44 has the same height of the holding surface as the table surface 4.

The configuration of the traveling circular sawing machine according to one embodiment is as described above. Various cutting processes of the workpiece W are performed as follows.

In the case of the parallel cutting process for trimming the width of the product, the forward / backward moving body 26 is moved forward by the forward / backward feeding means C, and the chucking means D approaches the traveling slit 17 and stops. In this state, the vertically moving frame 31 is lowered, and the upper claws 35 of the chucking claws 32, 32 are moved.
Open and wait. On the other hand, an operator supplies the work material W on the table surface 4 and pushes the work material W rearward so that the side end surface B comes into contact with the ruler surfaces 36 of the chucking claws 32, 32. When the setting of the work material W is completed, the upper claw 35 is closed and the work material W is clamped and held. Right angle ruler 4
0 is evacuated to a position indicated by a virtual line in FIG. 1 in advance.

When the workpiece W is clamped and held in this manner, the forward and backward feeding means C is controlled and driven by an NC controller (not shown), and the workpiece W is transferred to a position behind the table surface 4 by the chucking means D. I do. This operation ends when the front end face of the workpiece W has passed through the traveling slit 17. The rearward transfer of the work material W is performed on the table surface 4.
It is made light by the idle rolling rollers.

Thereafter, the NC control device drives and controls the forward and backward feed means C in the opposite direction to position the workpiece W at a predetermined cutting position. The material W is pressed and fixed to the table surface 4,
The circular saw unit A travels and moves. This first circular saw 1
By the traveling movement of No. 5, the processed material W is subjected to, for example, an edge dropping process. When the first cutting is completed, the pressing means B is opened, the next positioning is set, and the second cutting is performed by the traveling operation of the circular saw unit A as described above.

The above-described series of width-determining cutting operations are continuously and automatically performed according to the program of the NC control device. With this continuous operation, the cut products are sequentially transferred toward the front table surface 4. When only the work material W is cut off, the cutting process is completed. The chucking claw 32 approaches the traveling slit 17 and opens, and the cut off portion is discharged to the front end of the table surface 4. At the end of the cutting process, the scraps are processed by the operator's hand.

Next, a case where the work material W is cut obliquely will be described. At this time, after setting the right angle ruler 40 to the position indicated by the solid line in FIG. 1, the forward / backward moving body 26 is moved forward to set the angle ruler means E near the traveling slit 17. At the time of this oblique cutting, the vertically moving frame 31
And the chucking claw 32 is retracted from the table surface 4. On the other hand, the worker supplies the work material W to the table surface 4, moves the work material W to the angle ruler E side, and pushes it backward.

By this loading operation, as shown in FIG. 6, the front end face A and the left end face B of the workpiece W are each
Are set by pressing against the short side contact surface b and the long side contact surface a. At this time, since the long-sided contact surface a is located at the end and faces in the pushing direction, the operation is easy without any obstacle. When the setting of the workpiece W is completed, the clamp holding means F is operated to clamp and clamp the corner of the workpiece W.

When the workpiece W is gripped in this way, the NC control device controls and drives the forward / reverse feed means C to transfer the workpiece W to the rear position, and is further rotated by another NC control device. Control means 41 to drive the square ruler 4
The workpiece W is rotated and transferred by the contact surface a at 0 as shown in FIG. The transfer of the workpiece W is performed lightly by idle rollers (not shown) on the table surface 4.

Here, the workpiece W is transported in a state where the corners and side end faces are regulated and held, so that accurate positioning without displacement can be performed. When the positioning of the workpiece W is completed in this way, the workpiece W is pressed and fixed to the table surface 4 by the holding means B, and the circular saw unit A is moved to perform cutting.

When the oblique cutting is completed in this way, the clamping operation of the workpiece W by the holding means B is released, and the angle ruler E is moved forward by the feed driving means C. As a result, one of the cut workpieces W is pushed out to the front end of the table surface 4, so that the operator can perform the processing at the near position. Also after this,
Further, by moving the angle ruler E forward and releasing the grip of the corner, the remaining workpiece W can be processed at the same position.

In the above description, the workpiece W is rotated about its corner, and the angle is set. For this reason, even if the angle is changed, the reference position for dimension setting does not fluctuate in both the left and right directions and the front and rear directions, and it is not necessary to impose a complicated correction operation on the NC control device that performs the control movement in these two directions. Therefore, dimensional accuracy in oblique cutting can be improved.

In addition, when the workpiece W is supplied, only the short side abutting surface b protrudes from the table surface 4, so that the workpiece W is not obstructed when the workpiece W is transported in the front-rear direction. The work material W can be smoothly carried in not only from the front but also from the rear of the table surface 4.

In the above embodiment, the angle ruler means E
Is provided on one side (the left side in the figure) of the table surface 4, but it is optional to arrange it on the opposite side (the right side) or on both the left and right sides. When disposed on the right side, the angle ruler means E
Are arranged symmetrically, and the workpiece W is rotated clockwise in the drawing to set the angle.

In one embodiment, the clamp gripping means F is provided only at the corners of the workpiece W. However, in order to grip the workpiece W more strongly, the long side contact surface a Can also be provided corresponding to the vicinity of the free end of. In this case, in order to prevent the lower receiving piece 44 from interfering with the table 3 at the time of rotation, for example, a notch-type table configuration or a protruding-retractable table configuration is required. .

In one embodiment, the workpiece W is conveyed backward with the corner portion clamped and clamped, and the angle is set. However, in the case of a running saw that can be easily transported by the horizontal table surface, the square ruler 40 is used in advance. Even if the angle and the position are set in advance and the slanted work material W is supplied thereto, the angle cutting can be easily and accurately performed.

In one embodiment, the angle cutting ruler is applied to a running saw. However, the present invention can be similarly applied to a panel saw having a substantially vertical table surface. This case is different from the running saw in that when the workpiece W is received with the long side contact surface a being horizontal, the entire weight of the workpiece W acts on the contact surface a from the beginning. Therefore, in order to cope with this, it is better to provide another ruler for stably receiving the workpiece W on the extension of the contact surface a.

[0046]

As described above, according to the angle cutting ruler for a traveling circular sawing machine according to the present invention, angle cutting of a large plate-shaped work material can be performed smoothly, easily and efficiently. It has an excellent effect of being able to do so.
