Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when wood is subjected to precut processing such as joint processing, corner only processing, stud machining with studs, and vertical boring processing, the wood is sent before and after. The present invention relates to a pre-cut processing machine in which wood and the like are sequentially transferred by two gripping parts and are fed while being processed.

[0002]

2. Description of the Related Art A precut processing machine detects with a sensor,
After the wood sent to the stopper is clamped with a vise device to cut off the tip of the wood, it is sequentially clamped with a vise device at a predetermined position to process the joint, process only the vertical angle,
Pre-cut processing such as studless sagging notch processing and vertical boring processing is performed sequentially, and then the rear end is cut off to complete a series of processing.

As such a precut processing machine, there is known one in which wood to be processed is sent to a processing position by a roller rotated by a motor.

[0004]

As described above, in the case where the wood to be processed is sent by the roller, the wood slips on the roller, and it takes time to send the wood to a predetermined position which is positioned by the stopper. There was a problem of inefficiency.

Further, there is a problem that when one piece of wood is being sent, the next piece of wood cannot be sent and the work efficiency cannot be improved.

[0006]

According to the present invention, wood is conveyed on a conveying path, and the wood is clamped at a predetermined processing position to perform joint processing, corner-only processing, studless turret cutting, vertical boring, etc. In a pre-cut processing machine configured to sequentially perform processing in the pre-cut processing unit, a rear-end gripping unit that grips and transports the rear end of the wood is provided in the preceding stage of the pre-cut processing unit of the wood transport path, and the pre-cut processing is performed. A tip gripping portion that grips and conveys the tip of the wood is attached to the subsequent stage of the section.

[0007]

The precutting machine of the present invention is provided with a trailing end gripping portion for gripping the trailing end of the wood and a tipping gripping part for the tip of the wood at the front and rear stages of the conveying path with the precut processing part interposed therebetween.
The sent wood is detected by the sensor, hits the stopper, and is clamped with a vise device to cut the tip with a cutting saw.

At this time, the rear end gripping portion is driven, and the sensor of the rear end gripping portion detects and grips the rear end of the wood.

Then, after the clamp of the vise device is released, the rear end grip portion is driven to move the wood to the finishing portion.

Therefore, after the wood is clamped by the vise device to perform the finishing process, the vise device is released, and the wood is moved by the rear end grip portion.

When the trailing edge gripping portion moves to the next upper and lower corner-only portion, the vise device similarly clamps the wood to process the tenon with only the upper and lower corners.

After machining only at this corner, the rear end gripping portion moves the wood in the direction of the upper and lower boring portions, and boring is performed on the upper and lower parts of the wood.

When the tip of the wood is detected by the sensor of the tip gripper at any position where these processes are performed, the tip gripper grips the tip of the wood.

At this time, since the rear end of the wood is at the position of the cut and sewn, the rear end of the wood is cut, and when the cut rear end is short, it is dropped on the spot, but the cut rear end is long. At this time, the rear end gripper moves in the wood supply direction while discarding the cut rear end, discards it, and waits at a predetermined position.

When the above processing is not finished after the rear end is cut off, the tip gripping portion grips and moves the tip of the wood, and the vise device clamps at a predetermined position for further processing. ..

Further, when the next wood is sent at that time,
Similarly to the above, the sensor detects and the rear end grasping portion grasps the rear end of the wood while the tip is cut by clamping with the vise device.

As described above, after the trailing end of the previously fed wood is cut, the next timber is fed by the trailing end grip portion, so that the working efficiency is greatly improved.
