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

Referring to FIG. 2, for example, a horizontal band sawing machine 1 as a cutting machine is provided with a saw blade housing 3 which is movable in a vertical direction (a direction perpendicular to the paper surface in FIG. 2). A drive wheel 5 and a driven wheel 7 are provided opposite to each other in the housing 3, and a band saw blade 9 is wound around the drive wheel 5 and the driven wheel 7.
The saw blade housing 3 is provided with a fixed saw blade guide 11 and a movable saw blade guide 13 for guiding the band saw blade 9.

The position where the band saw blade 9 is moved up and down is the cutting position K. The cutting position K is located upstream (upper side in FIG. 2) of the cutting position K in the material feeding direction (vertical direction in FIG. 2). A feed conveyor 17 having a plurality of rotatable feed rollers 15 at intervals is arranged. A main body vise device 19 is provided near the upstream side of the cutting position K. The main body vise device 19 includes a fixed vise 19F and a movable vise 19M movable by a cylinder or the like in a direction perpendicular to the material feeding direction.

On the downstream side (lower side in FIG. 2) of the cutting position K, a front vise device 21 provided with feed vises 21A and 21B for sending out the cut product G is provided in a material feeding direction (vertical direction in FIG. 2). ). The feeding vise 21A and 21B are provided, for example, so as to be able to approach and separate from each other, and are distributed and clamped or unclamped with respect to the center of the product G.

A marking device 23 for marking the workpiece W and / or the product G is provided above the cutting position K and the front vice device 21.

According to the above configuration, the work W to be processed is carried onto the feed roller 15 of the feed conveyor 17 and placed thereon. By rotating the material feeding roller 15, the material is fed to the cutting processing position K side, and when the desired position of the work W reaches directly below the band saw blade 9, the material feeding roller 15 is stopped.

The work W is clamped by the cooperation of the fixed vise 19F of the main body vise device 19 and the movable vise 19M. In this state, the workpiece W is cut by lowering the saw blade housing 3 and rotating the band saw blade 9 while traveling.

The cut product G is supplied to the front vise device 21.
Clamped in cooperation with the feed vise 21A and 21B of
In FIG. 2, it is carried down.

As shown in FIG. 1, the marking device 23 includes a support frame 25 which extends horizontally in the Y-axis direction which is a direction orthogonal to the X-axis direction which is the material feeding direction. A Y-axis positioning cylinder 27 is provided in the support frame 25. A piston rod 29 is mounted on the Y-axis positioning cylinder 27, and a distal end (right end in FIG. 1) of the piston rod 29 is provided with a support block 31 so as to be able to move horizontally in the Y-axis direction.
A shaft carriage 33 is provided.

On the lower surface of the Y-axis carriage 33, a Y-axis linear guide rail 35 extending in the Y-axis direction is laid. A plurality of guide members 37 integrated with the support frame 25 are fitted to the Y-axis linear guide rail 35.

With the above configuration, the Y-axis positioning cylinder 2
By actuating 7 to extend and retract the piston rod 29, the Y-axis carriage 33 is moved in the Y-axis direction.

The Y-axis carriage 33 has a bracket 3
9, a Z-axis moving cylinder 41 is provided. A piston rod 43 is mounted on the Z-axis moving cylinder 41, and a support block 45 is attached to a tip (upper end) of the piston rod 43 with a nut 46 or the like.

A worm gear 47 is rotatably mounted on the right side of the Y-axis carriage 33 in FIG.
A worm 49 is meshed with the worm gear 47. Moreover, the worm 49 has a rotary drive motor 51.
Are connected. An upper portion of a rod member 55 extending in the Z-axis direction, which is a vertical direction, is rotatably supported by a bearing 53 provided in the support block 45, and
The lower part of the rod member 55 is mounted on the worm gear 47. The rod member 55 functions as a Z-axis linear guide and a rotary drive shaft.

A marking head 57 is integrated with the lower part of the rod member 55, and a front surface of the marking head 57 is clearly shown in FIGS.
, A marking sticker 59 protruding horizontally is provided.

With the above configuration, when the Z-axis moving cylinder 41 is operated to extend and contract the piston rod 43, the rod member 55 is moved in the Z-axis direction. When the rotary drive motor 51 is driven, the worm 4
9. The rod member 55 is rotated via the worm gear 47.

Therefore, when marking such as material and charge is applied to the end face of the cut product G, as shown in FIG. 2, the product G is fed by the feed vise 21A and 21B of the front vise device 21. Is clamped, and is conveyed downward in FIG. In this state, the marking head 57 is lowered to a position corresponding to the end face of the product G, and the marking patch 59 is directed to a position corresponding to the end face of the product G, that is , in the direction of the end face of the product G.
The marking head 57 is rotated so as to be directed . The product G can be marked by moving the front vise device 21 upward in FIG.

[0026] In the case of applying a marking on the end face of the workpiece W, as shown the marking head 57 from the state shown in FIG. 2 in FIG. 3, the marking Jaco 5 inverted allowed 180 degrees
9 can be marked on the end face of the work W by moving the work W downward in FIG. 3 and bringing the end face of the work W into contact with the marking sticker 59.

Also, as shown in FIG. 4, the marking head 57 of the marking device 23 is moved rightward in the Y-axis direction and the work W is moved downward in FIG. The workpiece W can be marked at any position on the end face other than the end face position of the work W.

Further, by turning the marking head 57 90 degrees from the state shown in FIG. 2 and moving it to the right in the Y-axis direction, the marking head 57 is moved to the position shown in FIG. 5 and positioned. Then, by marking the product G with the feed vise 21A and 21B and moving the front vise device 21 upward in FIG. 5, the outer periphery (side surface) of the product G can be marked. The marking head 57 is moved and positioned by the same operation, and the work W
Is moved downward in the X-axis direction, marking can be performed on the outer periphery (side surface) of the work W. Further, it is also possible to perform marking on the outer periphery (side surface) of the opposite side of the workpiece W and the product G.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. Although the cutting machine has been described as an example of the horizontal band sawing machine, other cutting machines such as a vertical band sawing machine may be used.
