2. Description of the Related Art Conventionally, when a material is cut with a band saw, for example, as a cutting machine, it is impossible for the operator to directly detect the cutting conditions for the material, the plate thickness, etc. of the material. The material is cut by determining the cutting conditions, determining the cutting conditions, and inputting it to the band saw machine.

Further, on the user side, in order to easily recognize the material, marking by coloring (red, yellow, black, etc.) with a colored spray or a brush is carried out to surely and easily manage the material of the material after cutting. I am going to do it.

[0004]

In such a conventional technique, the cutting conditions for the material to be cut cannot be automatically set, and the operator sets the cutting conditions and inputs them into the cutting machine. Because it had to be done, the work efficiency was poor.

Further, since marking for indicating the material and the like cannot be automatically performed, it is troublesome for the operator to confirm the material and the like and then mark the material with a colored spray or a brush.

Are rotatably supported by roller frames 23, 23 provided separately from the frame 19 over substantially the entire length of the material feeding path of the member M to be cut.

On the other hand, the vise mechanism section 7 comprises a main body vise mechanism 25 and a material feeding vise mechanism 27. The main body vice mechanism 25 is for holding and fixing the cut member M at a fixed position when the cut member M is cut, and is driven by the main body fixing vice jaw 29 and a fluid pressure mechanism 31 such as a hydraulic cylinder. Body movable vice jaw 33 that can freely move toward and away from the body fixed vice jaw 29
And is arranged immediately before the cutting position of the band saw blade 9. That is, the main body movable vice jaw 33 is moved by the fluid pressure mechanism 31 to sandwich and fix the member M to be cut between the main body fixed vice jaw 29. The above-mentioned color identification sensor 15 is provided on the rear side surface 29a in the X-axis direction of the main body fixing vise jaw 29, and the color applied to the side surface of the member M to be cut by the applying roller 35 as a mark attaching means described later. It is designed to detect Although not shown here, a front vise for sandwiching and fixing the member M to be cut may be provided on the side beyond the cutting position with the same configuration.

The material feeding vice mechanism 27 is for feeding the material to be cut M in the material feeding direction, and like the main body vice mechanism 25, the material feeding fixed vice jaw 37 and the material feeding movable vice jaw 39. It is configured so that it can be moved toward and away from the main body vise mechanism 25 by hydraulic pressure through sequence control. Further, the material feeding movable vice jaw 39 can freely move toward and away from the material feeding fixed vice jaw 37 through a fluid pressure mechanism 41 such as a hydraulic cylinder. The fluid pressure mechanism 41 is connected to the Y-axis in FIG.
It is supported so that it can move back and forth in the axial direction.

Further, as shown in FIGS. 3 and 4, a mark attaching means for applying a predetermined color as an identification mark on the side surface of the member M to be cut on the side surface of the member M to be cut, as shown in FIGS. 3 and 4. The coating roller 35 is vertically provided with its vertical position adjustable and rotatable. The coating roller 35 is made of a soft and highly elastic material such as sponge, and is divided into a plurality of layers 35a, 35b ... In the vertical direction as shown in FIG. It also contains a paint of a predetermined color. In other words, the color set in advance for indicating various information such as the material and the plate thickness is the layers 35 of the coating roller 35.
a, 35b ... The vertical position of the application roller 35 is adjusted by manually moving the operator up and down and regulating the up and down movement by a locking means (not shown) so that a predetermined color can be applied in a rotatable state. Alternatively, although not shown, a rack may be attached to the application roller 35 side, and a pinion that meshes with the rack may be provided on the material feeding fixed vice jaw 37, which is driven by a device such as a servo motor to move up and down. . As shown in the enlarged view of FIG. 3, the coating roller 35 slightly protrudes from the vice reference surface L, which is the inner surface of the material feeding fixed vice jaw 37, toward the member M to be cut and always contacts the member M to be cut. The predetermined color is applied to the side surface of the member M to be cut while retreating together with the material feeding vise mechanism 27 that has moved backward after the material feeding operation is completed.

The vice bed 43, as shown in FIG.
It is supported so as to be reciprocally movable in the X-axis direction along a suitable number (two in this embodiment) of guide rods 45 arranged in parallel with the X-axis direction. The guide rods 45, 45 are provided between the frame portion of the main body vise mechanism 25 and the support frame 47.

The support frame 47 is provided with an operating device 49 such as a hydraulic cylinder for reciprocating the vise bed 43 in the X-axis direction. When the operating rod 51 is extended, the material feeding vise mechanism 27
The whole moves forward in the feeding direction (X-axis direction in the figure), and the operating rod 51
When the sheet is contracted, the entire material feeding vice mechanism 27 is retracted.

A stopper 53 for restricting the forward position of the material feeding vice mechanism 27 is mounted on the vice bed 43, while the most advanced position of the material feeding vice mechanism 27 is provided below the main body vice mechanism 25. A switch 55 such as a limit switch that senses is attached to the stopper 53 so as to be freely engaged.

Further, a back gauge stopper 57 for restricting the retracted position of the material feeding vise mechanism 27 is provided at a position rearward of the material feeding vise mechanism 27 in the X-axis direction. The back gauge stopper 57 is screwed to a screw rod 59 provided below the main body vise mechanism 25 and the material feeding vise mechanism 27 so as to be rotatable in parallel with the guide rod 45. The screw 59 is connected to the rotary drive device 63 via a shaft 61. The back gauge stopper 57 is provided with an operating member 67 that is engageable with a switch 65 such as a limit switch attached to the vice bed 43 of the material feeding vise mechanism 27. By engaging the operating member 67 and the switch 65, the origin of the material feeding vise mechanism 27 and the last retracted position can be detected.

Next, the feeding and cutting process will be described. First, the operator adjusts the vertical position of the coating roller 35 so that the coating color of the coating roller 35 becomes a color indicating information such as the material and plate thickness of the member M to be cut. Then, the member M to be cut is carried into the material feeding vise mechanism 27. At this time, the side surface of the tip portion of the member M to be cut has a material feeding fixing vise jaw 3
It is carried in such that the color comes into contact with the coating roller 35 provided on the No. 7. Subsequently, when the material feeding vise mechanism 27 clamps and fixes the member M to be cut, the material feeding vise mechanism 27
Is moved in the X-axis direction to feed the material. When sending this material,
The main body vise mechanism 25 is in an open state, and the color identification sensor 1 mounted on the main body fixing vise jaw 29
5 detects the color applied to the side surface of the member M to be cut, and transmits the information to the control unit 13 of the cutting processing unit 3.

When the material feeding operation is completed, the main body vice mechanism 25 clamps and fixes the member M to be cut, and the material feeding vice mechanism 27 releases the clamp of the member M to be cut and retreats. At the time of this retreat, the coating roller 35 provided on the material feeding fixed vice jaw 37 colors the side surface of the member M to be cut.

On the other hand, the control unit 13 determines cutting conditions based on the transmission signal from the color identification sensor 15 and performs cutting processing. When the cutting process is completed, the process returns to the material feeding operation, and the above process is repeated.

As described above, since the material feeding vice mechanism 27 moves in a state where the coating roller 35 with the coating material is pressed against the side surface of the member M to be cut, it is possible to perform marking automatically, which is the same as in the conventional case. Moreover, the operator can manage the material after cutting without using a brush or a spray to color-code.

Then, the color identification sensor 15 reads the marking provided on the side surface of the member M to be cut and transmits the information to the control section 13, which detects the material and the like to determine the cutting condition. Since the cutting process is controlled by the operator, there is no need for the operator to input cutting conditions into the material cutting device as in the conventional case. Therefore, the material cutting device can be automated.

In the above embodiment, the coating roller 3
5 is provided in the material feeding fixed vise jaw 37 and the coating material is applied to the member M to be cut when the material feeding vise mechanism 27 retreats, but the present invention is not limited to this, and for example, in the vicinity of the main body vise mechanism 25 and the vise. It may be arranged such that it slightly projects from the reference plane L toward the member M to be cut and does not interfere with the movement of the material feeding vise mechanism 27, and the coating material is applied when the member M to be cut is fed.

Further, in the above-mentioned embodiment, the coating roller 35 as the mark adhering means is used to coat the side surface of the member M to be cut with the paint as the discrimination mark, and the color discrimination sensor 15 as the mark detecting means applies this coating. Although the case of reading has been described, the present invention is not limited to this. For example, a colored tape may be attached to the side surface of the member M to be cut, or a spray that sprays a predetermined color material instead of the application roller 35, or a brush-like one such as a marker may be used. May be.

Further, a bar code may be used as the identification mark, a bar code attaching means may be used as the mark attaching means, and a bar code sensor may be used as the mark detecting means.
