DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numbering device in a precut line for spraying codes and characters required for assembling a house on a lower surface of conveyed wood.

[0002]

2. Description of the Related Art Conventionally, as a numbering device of this kind, FIG.
As shown in FIG. 2, wood D conveyed onto a belt conveyor C hung between pulleys A and B is sprayed with ink from a numbering main body E mounted below the belt conveyor C, and a sign is applied to the wood D. A numbering device for numbering characters has been proposed.

[0003]

In the conventional numbering device constructed as described above, it is necessary to spray ink from the numbering body E onto the lower surface of the wood D, which is partially in contact with the belt from below the belt of the belt conveyor C. In other words, the wood D is transported on two belts of the belt conveyor C, ink must be sprayed from between these two belts, and the wood D is synchronized with the movement of these two belts. While the wood D is being numbered because the presser is not attached, 2
Since it is not synchronized with the movement of the two belts, there is a problem that characters and codes are shifted from predetermined positions of the two belts and are deviated from predetermined positions of the wood D, and furthermore, characters and codes are lost and become difficult to see. Further, there is a disadvantage that printing cannot be performed on the lower surface portion of the wood D in contact with the belt, and the printing width is narrow.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a roller conveyor for transporting wood mounted on a base, a numbered body having an ink ejection port provided upwardly between rollers of the roller conveyor, and a numbered body. Rails respectively mounted on both sides of the roller conveyor at right angles to the roller conveyor, two support members movably mounted on the rail, and mounted on one of the support members to protrude above the roller conveyor. A plurality of pinch rollers supported as described above, a pressing roller mounted on the other supporting member and protruding above the roller conveyor, and a second mounted on the other supporting member to rotate the pressing roller. A motor, a cylinder for moving one of the two support members, and a moving member having one end fixed to each of the two support members and a rack provided on a multi-end opposed surface Consists of a engagement device provided with a gear that engages the rack of the moving member, and transports the timber by the rotation of the pressing roller by the first motor.

[0005]

According to the present invention, by using a roller conveyor, the ink ejection port of the numbered main body can be mounted between the rollers, and the conveyed wood is pinched by the pinch roller and the pressing roller. By rotating the rollers or rollers of the roller conveyor by the first or second motor, the conveyed wood is conveyed at a constant speed, and the numbered characters and symbols of the conveyed wood are not shifted, and Since the belt or the like does not contact the lower surface of the wood, it can be numbered at any position on one side or the center of the wood.
