Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall perspective view of an apparatus according to an embodiment of the present invention, and FIG. 2 is a schematic structural view of the apparatus. This embodiment relates to an apparatus for cutting strip-shaped plate materials in the production of plate materials for producing cardboard. The cutting apparatus indicated by 1 in the figure is a stacking box 3 for stacking strip-shaped plate materials (hereinafter, referred to as works) 2 supplied from a pressure conveyor (not shown).
And a plurality of saw blades 4 in front of the upper part of the stacking box 3.
A pair of saw blade support bases 6 and 7 that rotatably support the saw blade shaft 5 and a saw blade drive shaft 8 of one (right side in FIG. 1) saw blade drive shaft 8 via a belt 9. The saw blade drive motor 10 is connected. The saw blade shaft 5 is mounted by replacing the one in which the number of blades and the pitch are set according to the specifications of the work, as appropriate, and rotationally drives downward from the rear to the front as shown by the arrow in the figure.

As shown in FIG. 2, an intermediate receiving shutter 12 that is connected to a non-stop gate cylinder 11 and can be inserted into the stacking box 3 is disposed behind the stacking box 3 and is driven by a pusher. Cylinder 13
A pusher 14 for delivering a work is provided which is connected to the movable box 3 and is movable below the stacking box 3 in parallel with the intermediate receiving shutter 12. Further, directly below the stacking box 3, driven by a lifter lifting motor 15,
A stacking lifter 16 that moves up and down between an upper limit position below the intermediate receiving shutter 12 inserted in the stacking box 3 and a work sending position is installed. The stacking lifter 16 supports and stacks the works 2 supplied in the stacking box 3 from below, and sequentially holds the uppermost works 2 so as to maintain an upper limit height that does not exceed the insertion position of the intermediate receiving shutter 12. Further, it is controlled to descend and to descend at a high speed to the work delivery position when the accumulated work 2 reaches a certain number (for example, 20 sheets), and to return to the upper limit position at a high speed after the work delivery is completed. Further, the intermediate receiving shutter 12 is inserted into the stacking box 3 prior to the high speed lowering of the stacking lifter 16 when a certain number of the works 2 are stacked on the stacking lifter 16, and the stacking lifter 16 is fed to the upper limit position after the work is sent out. When returning, it is controlled to return to the sideward retracted position.

A turret 17 having a shaft parallel to the saw blade shaft 5 as its center of rotation is arranged immediately below the saw blade shaft 5 mounting position on the front side of the stacking box 3.
In FIG. 7, three rows of hands 18 for gripping the work are attached to the outside so that the rotation loci intersect the saw blade 4 at equal intervals on the same circumference. Turret 1
The turret 7 is driven by a turret rotation drive motor 19 in a direction opposite to the saw blade 4 as indicated by an arrow in the figure.
The three rows of hands 18 are connected to the left and right connecting plates 2 respectively.
A fixed part 18a for connecting 0 and a plurality of movable parts 18b divided at positions intersecting with the saw blade 4 and each of which is openable and closable with respect to the fixed part 18a.
Is provided with a hand opening / closing cylinder 18c that opens and closes each movable portion 18b. A work transfer conveyor 21 is installed below the turret 17.

In front of the saw blade shaft 5 mounting position,
A dust collecting duct 22 is arranged in parallel with the saw blade shaft 5, and a dust collecting cover 23 is extended to the dust collecting duct 22 so as to cover the portions of the saw blades 4 from the front side to the upper side and the rear side. . A cover attaching / detaching cylinder 24 is connected to the dust collecting duct 22 so that each dust collecting cover 23 can be detachably rotated together with the dust collecting duct 22. Further, the dust collection duct 22 side portion of each dust collection cover 23 can be advanced from the front of the workpiece cutting position where the rotation locus of the hand 18 intersects the saw blade 4 so as to close the front side released portion of the accumulation cover 23. Dust collection auxiliary plates 25 are provided respectively. These dust collection auxiliary plates 25 are driven by an auxiliary plate drive cylinder 26 to advance to a position where they close the front side open portion of each accumulation cover 23, and are controlled to return to the front retracted position in accordance with the rotation of the hand 18. .

Work 2 jumping into the stacking box 3
Are supported and accumulated by the accumulation lifter 16. At that time, the stacking lifter 16 is sequentially lowered by the thickness of the work 2 so that the uppermost work 2 always holds the predetermined upper limit position, and when the stacked work 2 reaches a certain number (for example, 20), the intermediate receiving shutter. 12 is inserted to intermediately receive the following work 2. Then, the stacking lifter 16 descends at a high speed to the work feeding position, and the pusher 14 pushes a certain number of works 2 into the hand 18. afterwards,
The stacking lifter 16 moves up to the upper limit position at high speed, and the intermediate receiving shutter 12 returns to the retracted position to continue stacking.

Next, the cutting operation of the work 2 pushed by the pusher 14 and held by the hand will be described with reference to FIGS. 3 to 6.

The hand 18 holds a fixed number of works 2 accumulated at the horizontal position indicated by A in FIG. At this time, the dust collecting auxiliary plate 25 is in the retracted position as shown in FIG. When the work 18 grips the work 2 in the horizontal position as described above, the turret 17 rotates 30 °, and one of the hands 18 reaches a vertically downward position shown by B in FIG. 25 advances to the work cutting position. Then, the hand 18 reaching the position B is opened, and the cut work 2 is placed on the work transfer conveyor 21 as shown in FIG. Then, as shown in FIG. 6, the turret 17 further rotates 90 °, and the hand 18 presses the work 2 against the saw blade 4 during the rotation to cut the work 2. At this time, the dust collection auxiliary plate 25 retracts in accordance with the rotation of the hand 18. Further, during this time, the hand 18 which has released the work 2 at the position B returns to the position A and prepares to receive a new work 2, and the work conveyor 21 moves by one pitch. Then, the state shown in FIG. 3 is obtained again, and this is repeated thereafter. In addition, although the above-mentioned embodiment has described the device for cutting the strip-shaped plate material in the production of the board-shaped plate material, the present invention can be applied to various other devices for handling the strip-shaped plate material.

[0019]

Since the present invention is constructed as described above, the strip plate material can be cut efficiently. Further, since the cutting device according to the present invention does not have a complicated mechanism, the structure of the cutting device can be simplified and the processing accuracy can be improved.
