Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting feather stalks and the like used in a conventional construction method, and particularly to provide an effective processing means when cutting the same end face portion a plurality of times. It is what

[0002]

2. Description of the Related Art Feather materials such as rafters, braces, and corners
Unlike structural members such as columns and girders, those having an inclined end face in the longitudinal direction are often used. Of the above, for example, the end surface of the rafter is inclined in two plane directions, vertical and horizontal, but since it is formed in one plane, it can be processed into the required shape with one round sawing process. You can

Therefore, even when the long material is dimensioned while being transported in the longitudinal direction, the cut product can be made into a product each time the cutting is performed, so that simple feeding control is required. Accurate processing can be performed. This can be easily understood from the explanatory view of FIG. That is, in the drawing, a to d are cutting lines P and Q by a circular saw, and products are the products. Accurate machining can be performed only by feeding the workpiece W gripped by the chucking means R in a single direction.

[0004]

As described above, there is no particular problem in the case where the end face can be finished by only one cutting. However, if the same end face portion needs to be cut twice as in the case of the streaks in FIG. 4, the working becomes impossible. That is, the preceding processed material W1 cut off by the first cutting is the succeeding processed material W gripped by the chucking means.
This is because the positioning cannot be performed by the feed control as in 2.

In order to solve the above-mentioned problems, it is conceivable to hold the cut-off preceding processed material by another chucking means and position it by another dispensing control device. However, this raises the problem that the cost increases due to a plurality of control devices and the configuration becomes complicated.

The present invention has been made by paying attention to the above-mentioned problems of the prior art, and it is possible to accurately perform a plurality of cutting operations on the same end face portion of a cut workpiece with a simple structure and accurately. The present invention intends to provide a cutting and processing device for a feather material and the like.

[0007]

In order to achieve the above object, the cutting apparatus according to the present invention is configured as follows. That is, the gist thereof is that the preceding processed material cut by the circular saw and the following processed material gripped by the dispensing control device are connected by the connecting means arranged across both, and both processed materials are connected. The purpose is to control the transfer of materials together.

[0008]

Each time a cutting process is performed, the connecting means is operated to connect the cut-off preceding work material and the chucked trailing work material. By this connection, the former can be transferred together with the latter and the positioning can be controlled. Therefore, one dispensing control device is sufficient, and the entire configuration can be simplified. When the above positioning is completed, the connection by the connecting means is released to perform the cutting process.

When the connecting means is constituted by the piercing claws arranged across the preceding and following processed materials, the two can be connected only by simultaneously locking them on the surface of the processed material. The operation is simple and the configuration can be facilitated.

Reference numeral 20 denotes a saw traveling slit 21 provided on the table surface so as to pass through the center of rotation of the turntable 2.
The circular saw 21 protruding from the saw traveling slit 20 onto the horizontal table surface 2a is held by a traveling unit (not shown) and travels in the same direction as the saw traveling slit 20. The traveling unit is also equipped with an inclination adjusting means (not shown) to control the inclination of the circular saw 21 around the horizontal axis.

Reference numeral 22 is a reference ruler plate which is arranged on one side of the inner part of the horizontal table surface 2a, like the material feeding guide plates 3a and 4a.
When the piston rod is extended, the ruler surface of the guide rod 3 can be moved freely.
It is set at a position that coincides with the guide surfaces of a and 4a, that is, a transfer guide position. Also, when the piston rod contracts, its ruler surface is set to the rearward retracted position. The reference ruler plate 22 is arranged at an upper position which is not in contact with the horizontal table surface 2a.

Reference numeral 24 is a side pressure member provided on the other side corresponding to the reference ruler plate 22. The side pressure member 24 is movable by a pair of cylinders 25, 25 on both sides. When the piston rod is extended, The pressing surface is pressed toward the ruler surface. Further, when the piston rod contracts, the pressing surface is set to the retracted position. This lateral pressure member 24
Is made of a flat plate-like member and is set at a position slightly floating from the horizontal table surface 2a.

The reference ruler plate 22 and the lateral pressure member 24 are provided.
Is the position where the ruler surface and the pressing surface do not block the saw traveling slit 20 of the turntable 2, that is, the circular saw 2
It is a position where the protrusion of 1 does not interfere. Next, 26 is a cantilever-shaped mounting frame that is erected on one side of the base frame 1. 27 is a cylinder that is attached downward to the tip of the mounting frame 26. The pedaling member 2 is attached to the end of the piston rod.
Hold eight. The pedaling member 28 is arranged with the lower pedaling surface facing the horizontal table surface 2a.

The pedaling member 28 presses and clamps the workpiece W on the transfer path A toward the table surface 2a when the piston rod extends. When the piston rod contracts, it rises from the clamp position and is set to the retracted position. The tread surface D is made of a material that can be cut by the circular saw 21, such as wood or synthetic resin. Further, when the pedaling member is set to the retracted position, the slide base 1 described above is provided above the transfer path A.
A moving space D of 5 is formed.

The structure of the cutting apparatus according to the embodiment is as described above, and the cutting operation of the processed material W is performed as follows. Explaining the streak in FIG. 4 as a processing example, first, when the processing material W is supplied onto the carry-in conveyor 3, the moving base 7 is directed from right to left (the tip direction of the processing material W). It moves and the front end of the processed material W is contact | abutted by the end part regulation plate 12. At the same time, the piercing claw 14 is operated and chucked. By checking the moving position of the end regulating plate 12 at this time, the effective length of the processed material W can be measured.

On the other hand, the circular saw 21 is controlled in accordance with the workpiece W to be cut by controlling the rotation adjusting means of the turntable 2 and the inclination adjusting means of the traveling unit (both not shown).
The angle of the rotation direction and the angle of the tilt direction are set. Further, both the pedaling member 28 and the connecting means C are set to the retracted position.
The reference ruler plate 22 is set at the transfer guide position so that its ruler surface faces the transfer path A.

When the work material W can be received as described above, the dispensing base N is controlled and driven to transfer the work material W to be chucked in the longitudinal direction, Adjust to the specified position, that is, the cutting position The above-mentioned feed control of the work material W is performed by calculating each data such as the effective length of the work material W, the rotation angle of the circular saw 21, and the inclination angle.

After the work material W is set, the side pressure member 24 is operated to press the work material W by the pressing surface. By this operation, the processed material W can be straightened. Then, the treading member 28 is operated to press and clamp the workpiece W on the table surface 2a by the treading surface. By this clamping operation, it is possible to forcibly warp the workpiece W in the vertical direction. It is necessary to prevent the pedaling surface from coming into contact with the reference ruler plate 22 and the lateral pressure member 24 when the pedaling member 28 is operated.

When the clamping operation by the stepping member 28 is completed, both the reference ruler plate 7 and the side pressure member 9 are moved to the retracted position. Then, the circular saw 21 travels while protruding from the saw traveling slit 20, and the first cutting process is performed. If the first processing is performed in this way, then the second processing is performed.
Perform the second processing. This second processing is performed by the treading member 2
This is performed after releasing the clamp of No. 8 and positioning the workpiece W by the dispensing control device N. It goes without saying that the rotation angle and the inclination angle of the circular saw 21 are adjusted along with this positioning operation.

Since the positioning of the work material W and the operation after setting the angle of the circular saw 21 are the same as the operation at the time of the first cutting, the description thereof will be omitted. In this way, the processed material W
When the cutting of the front end of the workpiece is completed twice, the rear end of the workpiece W is then cut and the product is taken. Here, when the total length of the processed material W is longer than the product size, the cutting is performed at the intermediate position of the processed material W.

The first cutting process at the intermediate portion can be performed in the same manner as the first cutting process at the tip portion. However, the cutting material of the product portion (preceding processing material) W1 is cut off from the chucked processing material (subsequent processing material) W2 by the cutting processing of the intermediate portion, so that the cutting processing of the second time is left as it is. In this case, the required positioning control cannot be performed. In this case, the following operation is performed after the first cutting process.

That is, after the first cutting work is performed at the intermediate portion, the reference ruler plate 22 and the side pressure member 24 are operated with the treading member 28 being used, and the work materials W1 and W are processed.
Press 2 from the side. Then, in this side pressure state, the pedaling member 28 is retracted upward. Since the moving space D is formed above the transfer path A by the retracting operation, the pneumatic cylinder 19 is contracted at this time to move the slide base 15 from the retracted position to the position above the cutting portion.

When the connecting means C corresponds to the first cutting portion by the movement of the slide base 15, the piercing claw 18 is lowered by the third cylinder 16 and both the work materials W are processed.
1. Lock on the surface of W2. Since the piercing claw 18 is disposed so as to straddle both processed materials, the preceding processed material W1 and the following processed material W2 are integrally connected. After this connection, the supply / discharge port of the pneumatic cylinder 19 is opened, and then the lateral pressure operation is released.

In the above-mentioned state, the moving base 7 is controlled to move by the dispensing control device N, and the preceding processed material W1 is positioned via the chucked trailing processed material W2.
After the positioning, the work pieces W1 and W2 are pressed by the reference ruler plate 22 and the side pressure member 24, and the piercing claw 18 is removed from the work materials W1 and W2 in this side pressure state. After removal, the piercing claw 18 is set to the retracted position by the pneumatic cylinder 19.

The angle setting operation of the circular saw 21, the operation of the stepping member 28, the reference ruler plate 22, and the side pressure member 24 after this are the same as the first cutting in the intermediate portion described above, and the second operation is smoothly performed. A second cutting process can be performed. Note that the case of cutting the second product from the remaining trailing processed material W2 is the same as the processing of the above-mentioned intermediate portion, and therefore duplicated description will be omitted.

In the above embodiment, the piercing claw 18 constitutes the chucking means B for the work materials W1 and W2.
It may be a pair of holding claws that open and close in the horizontal direction. Further, in the embodiment, the case where the same end portion of the processed material W is cut twice has been described, but it goes without saying that the present invention can be applied when cutting is performed more times than that. The processed material, which has been subjected to the final cutting process, is a product and is carried out by the carry-out conveyor 4 to the rear.

[0033]

As described above, in the cutting apparatus according to the present invention, the cut-off preceding processed material is connected to the succeeding processed material by the connecting means, and both are controlled and transferred together. Therefore, a single transfer control device is sufficient, and the structure can be simplified, which is an excellent effect.
