And a cutter 21 for cutting the cutter into a predetermined length, and a holder 22 for supporting the cutter 21 on the cutter feeder 20.

The cutter 21 is preferably formed to be inclined in one direction a portion for cutting the discharge portion 2 with a blade of metal material.

The cutter conveying unit 20 is provided with a holder 22 to support the cutter 21 on the upper side, the cutter transport cylinder itself is mounted on the work table 100 so that the cutter 21 is moved forward, backward (31).

The discharge hole forming part 40 is installed in the vertical downward of the discharge part 2 of the silicon cylinder 1 mounted on the fixing jig 10, the fixture 44 mounted on the work table 100, An elevating cylinder 41 having a rod 42 mounted in the fixture 44 and drawn out and elevated above the fixture 44, and coupled to an end of the rod 42, and having a tip portion formed at an upper end thereof. It consists of a needle 43.

The molding needle 43 is preferably made of a metal material.

The control unit 60 determines whether the silicon cylinder 1 is mounted on the fixing jig 10, whether the cutter 21 is moved to the desired position and returned to its original position, and the rod of the lifting cylinder 41 ( An input unit 51 for inputting whether 42 is raised or lowered to a desired position, a microprocessor 50 for controlling the operation of each driving unit by reading the input signal, and the microprocessor 50 It is configured to include a drive unit 52 for driving the lifting cylinder 41 and the cutter feeder 30, the cutter feed cylinder 31 of the discharge hole forming section 40 by receiving the operation signal of the).

Hereinafter, the operation state and action of the cutting device having the configuration as described above.

Figure 5 is a flow chart showing an operating state of the discharge portion cutting device of the silicon cylinder according to the present invention.

When the worker mounts the silicon cylinder 1 to the fixing jig 10 (S1), the silicon cylinder 1 is sensed by the silicon cylinder detecting hole 14 mounted on the fixing jig 10 and the cutting operation is started. It is determined whether or not (S2).

At this time, if the silicon cylinder 1 is not detected by the silicon cylinder detection port 14, the worker refits the silicon cylinder 1 to the fixing jig 10, and the detection port 14 is connected to the silicon cylinder 1 ) Is detected, the detected signal is input to the microprocessor 50 and the next operation is performed.

The signal input in the step S2 is read by the microprocessor 50 so that the microprocessor 50 sends an operation control signal to the drive unit 52, and the drive unit 52 moves the cutter transfer cylinder 31. Operate (S3).

The operation of the cutter transfer cylinder 31 means that the cutter unit 20 is advanced to the discharge port 2 side of the cylinder cylinder 1 mounted on the fixed jig 10, where the forward action is performed by the cutter unit. Means that the holder 22 of the 20 is moved from the initial position toward the discharge part 2 side, and when the cutter part 20 is advanced, the cutter 21 of the cutter part 20 moves to the discharge part 2. It is possible to know whether the discharge part 2 has been cut according to whether it has passed.

Therefore, when the driving unit 52 operates the cutter transfer cylinder 31 in the step S3, the holder movement detecting port 32 mounted at the front end of the cylinder 31, that is, the discharge unit 2 side, is cutter. It is determined whether the discharge part 2 is cut according to whether the holder 22 of the part 20 is sensed (S4).

If the discharge part 2 is cut in the step S4, the next operation is performed. Otherwise, the drive part 52 continues to operate the cutter transfer cylinder 31.

When the signal indicating that the discharge unit 2 is cut is input to the microprocessor 50, the microprocessor 50 sends an operation control signal to the driver 52, and the driver 52 receiving the operation control signal is The cutter feed cylinder 31 is operated to return the cutter portion 20 to the initial position.

When the cutter unit 20 is returned, the holder transfer detecting hole 32 of the cutter transfer cylinder 31 detects that the holder 22 is returned, and inputs the detected signal to the microprocessor 50. The microprocessor 50 reading the signal sends a signal to the driving unit 52 to operate the lifting cylinder 41 (S5).

In the step S5, the rod 42 of the lifting cylinder 41 having the forming needle 43 at the end is raised to form discharge holes for discharging the silicon liquid in the discharge part 2, Whether the discharge hole is formed is determined whether or not the rod 42 is detected and confirmed by the lifting amount detecting opening 45 mounted to the cylinder 41 (S6).

If the discharge hole is drilled in the determination step (S6), the drive unit 52 returns the rod 42, otherwise the drive unit 52 continues to operate the lifting cylinder (41).

As described above, when the rod 42 is returned and the worker pulls out the silicon cylinder 1 from the fixing jig 10, the cutting operation of the discharge portion of the silicon cylinder is terminated.

The operation is repeated every time the worker mounts the silicon container 1 to the assembly jig 10.

As described above, the present invention provides an apparatus for cutting the ejection portion of the silicon barrel and to form the ejection hole through which the silicon liquid is ejected, so that the ejection portion cutting operation of the silicon cylinder can be more easily performed. It is a useful invention that prevents the risk of accidents that occur during operation, that is, the worker cuts on the blade when cutting the discharge port by applying excessive force.
