Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precut processing apparatus, and more particularly to a processing machine for comprehensively performing various kinds of processing such as cutting and mortice cutting on a structural material for wooden construction. .

[0002]

2. Description of the Related Art A processing machine for comprehensively performing various processes such as cutting and mortice on a structural material for construction is disclosed in Japanese Patent Application Laid-Open No. 5-169402 entitled "Precut Processing Machine". This device arranges vise means in the conveying path of the processed material, and also has a circular saw unit, a side surface processing unit (portion processing section), and an upper and lower surface processing unit (upper and lower corners, etc.) with respect to the same conveying path. It is arranged. Further, a first gripping means for gripping a rear end of the processed material to control and move the upstream end of each processing unit, and a second gripping means for gripping a front end of the processed material to controlly move the downstream part. It is equipped with.

In the conventional apparatus, when processing the front half of the processed material, the rear end of the processed material is gripped to perform a positioning control operation, and when processing the latter half of the processed material, the front end is gripped to perform positioning. In addition, the front and rear ends can be cut and the tenon over the entire length can be efficiently performed by a smooth transfer operation.

[0004]

In the conventional processing apparatus, when attention is paid to the second gripping means provided in the downstream portion, this gripping means is located in the upper and lower surface processing units (upper and lower corners only) from the rear carry-out position. Since it requires a long control stroke from the stud studs to the wood cutouts and the top and bottom borings to the vicinity of the side surface processing unit (tree mouth processing section), there is a problem that robustness is required and the configuration becomes extremely large. .

Further, in the conventional structure, the gripping means is inserted into the position of the vise means provided corresponding to the upper and lower surface processing units. Therefore, in order to avoid interference, the gripping means is the upper half part of the cross section of the work material. The vice means is adapted to clamp the remaining lower half. For this reason, there is a problem that the clamping force in the processed portion becomes weak, and in a processed material having a large height, the processing accuracy is deteriorated due to "tilting".

The present invention has been made by paying attention to the above-mentioned problems of the prior art, and provides a precut processing apparatus capable of simplifying the structure and performing high-precision processing under a strong clamp. It is the one we are trying to provide.

[0007]

In order to achieve the above object, the precut processing apparatus according to the present invention is configured as follows. That is, the main point is
Providing a conveying path for transferring the processed material in the longitudinal direction, a vise means for clamping and fixing the processed material to this conveying path, a circular saw unit for cutting the clamped processed material, and mortise processing of the left and right side surfaces of the processed material In a wood processing machine equipped with a side surface processing unit and a top and bottom surface processing unit for processing the upper and lower surfaces of the processed material,

A vise means is movably arranged between the side surface processing unit and the upper and lower surface processing units, and tip holding means which is controlled and moved by positioning control means is provided on the rear side of both processing units. The gripping means corresponds to the vise means and the tip of the processed material in a switchable manner.

[0009]

When the tip of the processed material reaches between the side surface processing unit and the upper and lower surface processing unit, the tip portion is clamped by the vise means. After the tip gripping means is connected to the vise means, the positioning control means controls and moves. Positioning of the workpiece by this movement control can be performed within the movement range of the vise means.

When the vise means reaches the rear end of the moving range, both the clamping of the workpiece by the vise means and the connection of the vise means by the tip gripping means are released. Then, the tip of the processed material is directly clamped by the tip gripping means.
After clamping, the tip end gripping means is controlled and moved by the positioning control means. Positioning of the processed material by this movement control can be performed within the movement range of the tip gripping means.

Of the above, the X-axis moving base 27 has a basic column spacing of 1
It has a moving stroke of more than the pitch.

F is set to the rear side of the vice means 11 and the conveying path A
This tip gripping means F is arranged so as to be movable in any direction. This tip gripping means F has an upper clamp claw 40 corresponding to the tip of the workpiece W and a lower connecting claw 42 corresponding to the rearward extending rod 41 in a bifurcated shape. Prepare (Refer to FIG. 3) The tip gripping means F has a moving position set by the positioning control means G. The extension rod 41 is fixedly provided on the rear moving base 4b provided with the vise means 11. The extension rod 41 is attached and detached by the connecting pawl 42 by the pneumatic cylinder 43, and the workpiece W is attached and detached by the clamp pawl 40 by the pneumatic cylinder 44.

The configuration of the precut processing apparatus according to the embodiment is as described above, and various processing such as cutting and mortise cutting is performed as follows. To do so, first, the work material W is supplied onto the carry-in conveyor 2, and the work material W is transferred rearward by the rotational driving of the conveyor. In transferring the work material W, the stopper means C is projected to the transport path A in advance, and the moving vice means 8 at the upstream portion of the circular saw head B is moved forward, that is, the vice means 8 and the circular saw. Set the interval of this head B open.

When the tip of the work material W comes into contact with the stopper means C, the transfer is stopped and the work material W is clamped and fixed by the vise means 8. Then, in this state, the tip is dropped and cut. When the cutting process is completed, the stopper means C is retracted, and then the pneumatic cylinder 5 moves the clamped vise means 8 rearward. By this operation, the tip of the processed material W passes through the fixed vise means 9 and reaches the processing regions of the side surface processing units Da and Db.

Since the pneumatic cylinder 5 has a constant stroke, the workpiece W moves backward by a fixed amount. After the transfer, the processing material W is clamped and fixed by the fixed vise means 9, and then the side surface processing units Da and Db are respectively subjected to X.
The tenon is controlled and driven in the axis, Y-axis, and Z-axis directions to perform tenon processing such as a female tenon on the side surface. This mortise processing can be performed at several places within the X-axis movement range of the side surface processing units Da and Db. During this processing, the moving vise means 8 may be returned to the front position after releasing the clamp.

When the processing of the vicinity of the tip end by the side surface processing units Da and Db is completed, the pneumatic cylinder 43 is operated to connect the connecting claw 42 to the extension rod 41, and the positioning control means G moves the moving base 4b. The vice means 10 is operated to move forward via. When the vise means 10 reaches the tip position of the workpiece W by a predetermined amount of movement,
The vice means 10 is closed and the tip of the processed material W is clamped and fixed over the entire height. After the clamping, the vice means 10 is controlled to move rearward, and the next processing portion is moved to the side surface processing unit D.
It corresponds to a and Db.

The mortise processing by the side surface processing units Da and Db is performed while the work material W is clamped by both the fixed vise means 9 and the moving vise means 10. When the moving vise means 10 reaches the rear moving end as the tenon processing proceeds, the clamping operation of the workpiece W by the vise means 10 and the connecting operation of the extension rod 41 by the connecting pawl 42 are released. Then, the other clamping claw 40 is moved forward by the positioning control means G, and its end is made to correspond to the tip of the workpiece W, and then clamped by the pneumatic cylinder 44.

When the sandwiching from the vise means 10 to the clamp claws 40 is completed as described above, the positioning control means G sets the processing position while moving the workpiece W backward, and the side surface processing units Da and Db are set. Alternatively, the upper and lower surface processing unit E is operated to perform processing such as tenon. That is,
When the tip of the processed material W reaches the processing area of the upper / lower surface processing unit E and is supplied over the processing areas of the other side surface processing units Da and Db, the clamping operation is performed by the clamp claw 40 and the vise means 9. , Select the required processing unit and perform various types of mortise processing.

For example, when square holes are formed on the upper and lower surfaces of the workpiece W, the Y-axis moving base 28 is moved by the Y-axis movement control means Ey to move the corner-only heads 24, 24 to the conveying path A. Set at the center of the material W. After selecting the machining head, the movement control means Ex in the X-axis direction performs positioning in the longitudinal direction, and the square hole machining is started. Further, if the side surface processing units Da and Db are controlled to move in the X-axis direction and the turret head 21 is positioned during the processing of the square hole, it is possible to perform processing at two positions in the front-rear direction simultaneously or continuously.

When the work material W is to be sandwiched, the vise means 9 is operated to clamp and fix the work material W to prevent positional deviation. Also, the clamp claw 40
If it is confirmed that the work material W has reached the predetermined length during the transfer by, the transfer is stopped, the circular saw unit B is operated, and the work material W is cut to a predetermined size. The constant-size cutting of the processed material W is performed during the transfer by the vise means 10 for the short material.

When various processes such as the front and rear cutting process and the tenon process over the entire length are completed as described above, the work pieces W are carried out by the clamp claws 40 after releasing the clamps of all the vise means 8-11. After being transferred to the conveyor 3, the conveyor is driven after the transfer to carry it.

When the rear end of the processed material W reaches the processing area of the side surface processing units Da and Db after the above-mentioned constant-size cutting, the succeeding processed material W is supplied and transferred by the carry-in conveyor 2 and the front end is processed. Make a cut and drop and make it stand by. Then, when the preceding work material W is transported backward and reaches the processing area of the upper and lower surface processing unit E, it is immediately fed at a constant size to start cutting by the side surface processing units Da and Db. Thus, the processing efficiency can be improved by simultaneously processing the two front and rear processed materials W.

In the above embodiment, the extension rod 41
Is fixed to the vice means 10 side, but it may be fixed to the other tip holding means F side. In this case, the attachment / detachment operation is performed between the extension rod 41 and the vise means 10. Further, in one embodiment, the side surface processing units Da and D are formed by the dimensional feed of the vise means 8 for the processed material W whose tip has been dropped.
It is supplied to the processing area b. However, if the contact-type stopper means is provided in the processing area, the material can be fed by simply feeding the conveyor.

[0031]

As described above, in the precut processing apparatus according to the present invention, positioning is performed by controlling and driving the vice means of the conveying path in the processing unit. For this reason,
The control stroke of the tip gripping means can be shortened as much as possible, and the overall configuration can be simplified. Further, since the clamp regions of the tip gripping means and the vise means are divided, there is no problem of interference, and an excellent effect that high precision machining can be performed under a strong clamp is exhibited.
