Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting waste processing apparatus in an apparatus for cutting and forming a V groove on a cardboard.

[0002]

2. Description of the Related Art Wood, cardboard,
Generally, plastics are used, but wood is
It is a material that has been used for a long time and is outstanding in that it has excellent breathability, water absorption, robustness, etc. and that it gives a high-class feeling. However, since wood is currently expensive and it is necessary to refrain from using it as much as possible from the viewpoint of resource conservation, it has been conventionally attempted to process cardboard into a board resembling wood. There is. For example, a cardboard with a wood-patterned decorative paper attached on one side is cut into strips, and a W cut consisting of two V grooves in the longitudinal direction is formed on the surface of the strip opposite to the decorative paper,
By folding and sticking the strips at the W-cut position, it is possible to form a thick sheet-like plate material that feels like a wooden board.

By the way, when V-grooves are cut and formed on a cardboard by a cutting blade, cutting chips may remain on the cutting edge of the cutting blade. Progress is hindered and clogging occurs. For this reason, it is necessary to remove the cutting scraps one by one, but the work of removing the cutting scraps has conventionally been done only manually, which hinders the complete automation of the V-groove cutting process.

[0004]

The present situation is that the removal of cutting chips when forming V-grooves on a cardboard can only be done manually as described above, but this can be done manually. If not set, complete automation of the V-groove cutting process cannot be realized.

The present invention has been made to solve such a problem, and an object thereof is to realize automation of cutting waste processing in a cardboard V-groove cutting device.

[0006]

DISCLOSURE OF THE INVENTION The present invention relates to a cutting waste processing apparatus in a cardboard V-groove cutting apparatus for cutting and forming V-grooves on the lower surface of cardboard with a cutting blade. A first position, which is arranged below the blade, prepares for cutting waste treatment ahead of the cutting edge of the cutting blade in the direction of travel of the cardboard, and hands the cutting waste behind in the direction of travel behind the first position in the direction of travel. A first waste treatment bar that is movable between a second position and a third position that is further behind the second position in the traveling direction, and is disposed behind the first waste treatment bar in the traveling direction. The cutting scrap is sandwiched between the first scrap processing bar that has moved to the second position and the cutting scrap that is interlocked with the movement of the first scrap processing bar from the second position to the third position. It is possible to move it backward from the cutting edge so that it can be separated from the cutting edge. A first waste treatment bar drive for holding the waste treatment bar and the first waste treatment bar at the first position at all times and moving the first waste treatment bar to the second and third positions at a predetermined timing. Means and the second waste treatment bar are always held in a standby position to prepare for the movement of the first waste treatment bar to the second position, and the third waste treatment bar has a third position.
Second waste treatment bar driving means for moving the second waste treatment bar rearward in the traveling direction in conjunction with the movement to the second position, and the movement of the first waste treatment bar to the third position and the second operation associated therewith. It is characterized by comprising an air nozzle for ejecting compressed air so as to blow away the cutting waste separated from the cutting edge by the movement of the waste processing bar in the discharging direction, and a discharging means for discharging the blown cutting waste.

[0007]

The first waste treatment bar stands by at the first position in front of the cutting edge of the cutting blade in the traveling direction of the cardboard prior to V-groove cutting for each cardboard. At this time, the second waste processing bar is held at the standby position separated from the rear of the first waste processing bar. Then, when the V-shaped groove is cut and formed on the lower surface of the cardboard by the cutting blade to generate cutting scraps, the first scrap processing bar moves to a second position rearward in the traveling direction and cuts down from the cutting edge of the cutting blade. The waste is sandwiched between the second waste processing bar and the first waste processing bar further moves to a third position rearward in the traveling direction, and in conjunction with this, the second waste processing bar moves the first waste processing bar to the first waste. The cutting chips move between the processing bar and the cutting bar, and the cutting chips are separated from the cutting edge of the cutting blade. Further, when the cutting debris is separated from the cutting edge in this way and the first debris processing bar is returned to the front in the traveling direction to release the cutting debris, the compressed air ejected from the air nozzle blows the cutting debris and blows it away. The scraps thus cut are discharged by the discharging means.
