With the above configuration, the first work detecting device 31
Switch 29 provided on the second work detection device 25 and the second work detection device 25
The distance L from the optical axes K1 and K2 is L> 2 × ^φmax , so that the second work detecting device 25 does not react even if the maximum work enters between two works. This is illustrated in FIG.
When the first work detection device 31 detects that the work W of 4 in FIG. Since there is a possibility that the work W has started cutting the work W, NO. 5 to store the work W
Is required.

With the above-described configuration, the operation of the cutting control process P1 will be described with reference to the flowchart shown in FIG.
It detects whether the photoelectric switch 29 of the work detection device 25 (level 2) has reacted. The photoelectric switch 29 does not react even if the work W simply passes. If fullness is detected by the photoelectric switch 29 of the second workpiece detection device 25, cutting is stopped in step S2, and if there is no level 2 response, the process proceeds to step S3. Step S
In step 3, a cutting instruction read is performed, and the flow advances to step S4.

In step S4, the work sorting / storing device 15 (referred to as area A) for storing the long work W,
It is determined whether to use the short material storage device 17 (referred to as area B) or one of them. When using the work sorting and storage device 15 (area A), the process proceeds to step S5.

In step S5, the first work detecting device 31

When the short material storage device 17 (area B) is used in step S4, step S5
Skip to step S6.

At step S6, material feeding, cutting is started at step S7, cutting is completed at step S8, and a carry-out command is issued at step S9.

Then, at step 10, a next cutting instruction lead is entered. When the photoelectric switch 29 of the first work detection device 31 (level 1) detects that the work W is full in step S5, step S1 is performed.
Next, the instruction to cut the work W scheduled to be cut is given. Then, the work W (No. 5 work) is continuously stored in the work sorting and storing device 15.

If the next disconnection instruction is read in step S10, the flow advances to step S11 to proceed to the next step depending on the presence or absence of the next disconnection instruction. That is, if there is no instruction, the control process P1 ends and there is an instruction. Time is Step S
Return to 1 and continue the sorting and storing process.

If a carry-out command is issued in step S9, and if a carry-out instruction is issued in step S12 in the transfer control process P2, a carrying process is performed in step S13.

With the structure and operation as described above, the work W cut by the band sawing machine 1 is fed by the front vice device 13 and is successively transferred to the predetermined work sorting / storing device 15 via the kicking device 11. When the W is stored and the first work detection device 31 detects fullness, the continuous cutting of the band saw machine 1 is stopped, and the cutting of the next work of a different length to be cut is started.

Then, the work W is stored in the work sorting / storing device 15, and the cutting is stopped when the second work detecting device 25 detects that the work W is full. The first work detection device 3
When the full state is detected in step 1, the work W to be cut next is cut by the band sawing machine 1, and the work W is stored in another work sorting storage device 15.

Thus, continuous cutting can be performed without stopping the cutting of the band sawing machine 1.
