DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp device for a wood working machine, and more particularly to a device for clamping wood during cutting and cutting of wood.

[0002]

2. Description of the Related Art Generally, when processing wood, the wood (work, material wood) is conveyed from the upstream side by a driving roller conveyor or the like, and the conveyed wood is clamped and stopped at a processing position by a clamp device. Cut by,
Cutting and processing.

As a conventional clamping device for a wood processing machine, as shown in FIG. 2, wood A conveyed from an upstream side on a driving roller conveyor 2 is positioned by a material stopper 3 at a predetermined position. To stop. A signal indicating that the positioning of the wood is completed by the sensor 5 is sent to the clamp device 100, the cylinder rod 10a of the air cylinder 10 of the clamp device 100 is extended, and the wood A is sandwiched and fixed by the clamp plate 10b at the tip of the cylinder rod 10a. I was letting it. Generally, the air cylinder 10 and the clamp plate 10b of the clamp device 100 are respectively provided before and after the position of the cutter 4, and the cutter 4 is moved between the two clamp plates 10b to cut and cut the wood A.

After the wood A is cut and cut by the cutter 4, the clamp device 100 is operated again to shorten the cylinder rod 10a of the air cylinder 10 and is released from being fixed by the clamp plate 10b. Open wood A
Was transported downstream by the drive roller conveyor 2.

[0005]

In the conventional clamping device 100 for a wood working machine shown in FIG. 2, when the wood A is positioned at a predetermined stop position, the sensor 5 senses this and the sensor 5 The air cylinder 10 of the conventional clamp device 100 is actuated by the signal from the controller 10 and the wood A is clamped by the clamp plate 10b.

After the machining, it is necessary to shorten the air cylinder 10a and open the clamp plate 10b.

[0007] Therefore, the transport time of the wood A, the cutter 4
In addition to the processing time, the opening and closing time of the clamp plate 10b by the air cylinder 10 of the clamp device 100 also takes time for each piece of wood, and in a factory that processes a large amount of wood, further shortening of the working time is an issue. there were.

[0008]

In order to solve this problem, in a clamping device of a wood working machine for clamping wood conveyed on a driving roller conveyor, a clamping device is provided at a tip of a cylinder and a cylinder rod. The plurality of rotating clamp rollers, the plurality of rotating clamp rollers, the plurality of free-rotating presser free rollers located on the widthwise opposite side of the drive roller conveyor, and stop the lumber by contacting the tip of the conveyed lumber. It consists of a material stopper and a cutter that cuts the stopped wood. Continues to rotate, and after the wood is cut, the stopper is removed, and the wood turns. Suggest clamping device wood processing machine, characterized in that it is conveyed immediately to the downstream direction by the rotation of the rotation driving roller conveyor clamp roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIG. 1 showing a plan view of a clamping device of a wood working machine according to an embodiment of the present invention. FIG. 2 shows a plan view of a conventional clamping device of a wood processing machine.

The clamping device 1 of the wood processing machine comprises an air cylinder 10, a rotary clamp roller 11 provided at the tip of a cylinder rod 10a of the air cylinder 10, and a press-free roller 12. 2 is a drive roller conveyor, 3 is a material stopper, 4 is a cutter, and 5 is a sensor.

In this embodiment, the air cylinder 10, the rotating clamp roller 11, and the presser free roller 12 of the clamp device 1 are provided in parallel in the upstream and downstream directions of the wood conveyed on the drive roller conveyor 2, respectively. One or three or more may be provided as another embodiment.

Each air cylinder 10 is located on the upper side surface of the drive roller conveyor 4 and has a cylinder rod 10.
a is arranged such that the direction of expansion and contraction of a is perpendicular to the side surface of the drive roller conveyor 2.

A rotary clamp roller 11 is provided at the tip of each cylinder rod 10a so as to be rotatable with the rotation axis set in the vertical direction. The rotary clamp roller 11 is rotated by a rotary drive source (not shown).

The presser free roller 12 is provided at a position opposite to the rotary clamp roller 11 on the side opposite to the width direction of the drive roller conveyor 2, and the wood conveyed on the drive roller conveyor 2 relative to the rotary clamp roller 11. Sandwich. The presser free roller 12 is provided with a rotation axis centered in a vertical direction, and its rotation is freely rotatable about the rotation axis center.

When the sensor 5 detects that the wood A conveyed by the driving roller conveyor 2 has passed between the plurality of rotating clamp rollers 11 located on the side surface of the driving roller conveyor 2, the material A is moved to a predetermined position. The stopper 3 moves on the drive roller conveyor 2 and comes into contact with the conveyed wood A to stop it.

Next, the air cylinder 10 of the clamp device 1
Is operated, the cylinder rod 10a is extended, and the rotary clamp roller 11 is pressed in the direction of the wood A, and the rotary clamp roller 11 and the pressing free roller 12 opposed to each other hold the wood A.

The wood A comes into contact with the material stopper 3 at its tip, and the both sides are pressed by the rotating clamp roller 11 and the press-free roller 12, respectively, and stop at a predetermined position on the drive roller conveyor 2. At this time, the rotary clamp roller 11 keeps pressing the wood A while rotating, and the drive roller conveyor 2 also keeps rotating.

The stopped wood A is cut or cut into an appropriate shape by the cutter 4 to process the wood A.

When the processing is completed, the material stopper 3 is moved from above the drive roller conveyor 2. By eliminating the front stopper, the wood A is immediately conveyed downstream on the drive roller conveyor 2 by the rotation of the drive roller conveyor 2 and the rotation of the rotary clamp roller 11.

The air cylinder 10 of the clamp device 1 appropriately shortens the cylinder rod 10a of the air cylinder 10 to receive the next wood A, and widens the interval between the rotary clamp roller 11 and the press-free roller 12.

This operation is sequentially repeated.

[0023]

According to the present invention, the apparatus for clamping wood for processing can immediately flow the wood to the downstream side after processing such as cutting and cutting, and can open and close the conventional clamp.
In particular, the opening time can be reduced.

[0024] Therefore, by shortening the processing time of one piece of wood, it is possible to greatly reduce the working time in a factory that processes a very large number of pieces of wood.
