Is transmitted to the slide base 7 through the sliding of the slide base 7, whereby the slide base 7 reciprocates. Reference numeral 77 denotes a stopper for stopping the rotation of the pin hold rod 52.

On the other hand, the sliding of the roller 75 in the engaging groove 73 is related to the swing of the pin hold portion 5. FIG.
As shown in (A), when the roller 75 is at the position of the center “a” of the engaging groove 73, the pin hold portion 5 (pin hold rod 52) is at the origin position A, and this position is Is the starting point of the rocking motion. And as the crank wheel 74 rotates, the slide base 7 moves to the right,
As shown in FIG. 10B, the roller 75 slides upward in the engagement groove 73, and the sliding roller 55 slides upward along the guide 6, so that the pin hold rod 52 gradually rotates. When it is moved parallel to the guide needle 31, it hits the stopper 77 and stops. At this time, the sliding roller 55 is apart from the guide 6. This is the end point of the swing of the pin holding part 5 and the starting position B of the pin insertion part 3
It is. FIG. 10C shows this position. At this time, the roller 75 is at the position “b”. As the crankwheel 74 further rotates, the roller 75 comes to the position indicated by “c” in FIG. 10C, and this is the stroke end of the slide base 7. When the crankwheel 74 further rotates and reaches the position indicated by “d” in FIG. 10C, the slide base 7 returns to the starting position B. At this time, the pin hold rod 52 is in a position parallel to the guide needle 31. When the crank wheel 74 further rotates, the roller 75 slides upward in the engagement groove 73, and the sliding roller 55 slides downward along the guide 6, so that the pin hold rod 52 is moved to the origin position. Return to A. Thus, the swing of the pin hold unit 5 is determined by the relationship between the moving position of the slide base 7 and the contact position with the guide 6.

Thus, the pin holding section 5 is
Origin A provided at the starting position and starting position B provided at the pin insertion portion 3
At the starting position B, advance toward the aquaculture rope 41, and reciprocate to return to the starting position B.

The locking pins 20, 21 are made of an elastic material having an elastic force such as resin.

Next, based on FIGS. 5 to 10 and FIG.
The operation of the device of the present invention will be described. First, the locking pin 21 is set at the origin position A in advance. When the start signal is input, the pin holding solenoid 54 of the pin holding section 5 is turned on (O
N) (S.1), and the pin spring rod 52 projects because the compression spring 53 is compressed. Thereby, the hole 52
The locking pin 21 at the origin position A enters into the area a (the pin hold rod 52 holds the locking pin 21).

When the operation detection sensor 57 detects the operation of the pin hold solenoid 54, it outputs an ON signal (S.2). As a result, the pin insertion section 3 starts to be driven (S.31), and the motor (not shown) is rotated to rotate the crank wheel 74. In addition, the cutter motor (not shown) is rotated to drive the cutter 14 of the pin supply unit 1 (S. 32).

The rotation of the crank wheel 74 causes the pin hold rod 52 of the pin hold portion 5 to move
Is rotated along the guide 6 while holding. As a result, the pin hold rod 52 takes out the locking pin 21 from the pin supply drum 11. The mechanism of the swing rotation of the pin hold unit 5 is as described above ([001
5]). Thus, the pin hold unit 5 rotates to the starting position B (FIG. 6).

When the crankwheel 74 further rotates, the slide base 7 further moves to the right by the mechanism described above ([0014] and [0015]) (FIGS. 6 and 7).

When the slide base 7 moves to the right, the tip of the locking pin 21 hits the guide plate 33 and is pushed in.
It enters the groove 32 of the guide needle 31. In this state, the locking pin 21 is inserted into the culture rope 41 together with the guide needle 31 (FIG. 7).

When the slide base 7 reaches the stroke end (FIG. 8), the end point sensor 35 detects this (S.43) and turns off the pin holding solenoid 54 (S.53). In this state, since the pin hold part 5 retreats leftward, the locking pin 21 remains on the culture rope 41 (FIG. 9).

When the slide base 7 returns to the origin position A and the pin hold unit 5 returns to the origin position A, the origin sensor 58 of the pin insertion unit 3 is turned on (S. 41), and the pin insertion unit 3 is driven. Stops (S.51).

The origin sensor 58 of the pin insertion section 3 is turned on (O
N), the rope feed unit 4 is driven, and the culture rope 4
1 starts to be sent (S.61). When the preset count number for one pitch matches the count number by the encoder 48 (S.71), the rope feeding unit 4 stops (S.81).

On the other hand, in step 32 (S. 32), the cutter motor driven by the operation detection sensor 57 being turned on (ON) has the cutter origin sensor 17 turned on (O
N) (S.42) and stop (S.5).
2).

Further, when the cutter origin sensor 17 is turned on (O
N), the pin supply unit 1 is driven (S.62). When the drive shaft 12 makes one rotation, the pin supply drum 11 moves by one pitch. When one rotation of the drive shaft 12 is detected by the pin supply unit origin sensor 18 (S.72), the drive motor (not shown) stops (S.72). .82).

It is determined whether the series of steps is continuous or stopped (S.9). In the former case, the series of steps is repeated.

According to the above embodiment, the following effects can be obtained. First, the insertion of the guide needle 31 and the insertion of the locking pin 21 do not need to be performed sequentially as in the related art, but can be performed simultaneously. Therefore, regarding the operation relationship between the two, each part can be operated in a superimposed manner, so that there is no need for a temporary stop or synchronous operation, there is no waiting time for inserting the locking pin 21, and the mechanism is simplified. As a result, the insertion of the locking pin 21 is a simple operation, and is quick and reliable (in the embodiment, about 0.8 seconds per cycle).

Further, the insertion of the locking pin 21 into the culture rope 41 can be performed by a simple reciprocating movement of the guide needle 31, which contributes to quick processing of mounting the locking pin 21.

Since the pin hold section 5 is swingable, the removal of the locking pin 21 by the pin supply section 1 and the delivery of the locking pin 21 to the pin insertion section 3 do not interfere with each other's operation. ,
In addition, it can be performed at the closest positional relationship. Thereby, each operation is simplified, which contributes to quick and reliable processing of mounting the locking pin 21.

Further, the swinging and the forward / backward movement of the pin hold unit 5 are performed by the rotation of the crank wheel 74, and the driving source is the same. This contributes to simultaneous processing of insertion of the guide needle 31 and insertion of the locking pin 21 and quick and reliable processing of mounting the locking pin 21.

Further, since the elasticity of the locking pin 21 is utilized, the locking pin 21 can be reliably inserted into the guide needle 31 irrespective of the simple reciprocating movement of the guide needle 31.

The present invention is not limited to the above embodiment. For example, without using the guide 6,
Can be performed by an actuator different from the forward / backward movement.

When the locking pin 21 is inserted into the guide needle 31, the entire pin holder 5 is inclined toward the guide needle 31 without providing the guide plate 33, and the lock pin 21 is directly connected to the guide needle 31. It may be inserted.

The pin holder 5 can be installed in the lateral direction of the slide base 7 instead of being installed above the slide base 7 as in the illustrated example.

The timing of cutting the locking pin 21 is arbitrary. For example, the locking pin 21 is not only supplied to the take-out position (origin position A) in a state of being cut in advance as shown in the figure, but also sent to the take-out position (origin position A) in a continuous state, and is held in a pin hold state. The cutting may be performed by the cutter 14 at the same time as being added to the rod 52.

The kind of the applicable locking pin 21 is arbitrary. For example, as shown in the drawing, a type in which the locking portions are provided on both sides of the end portion (both age types) or a type in which the locking portions are provided on one side (single age type) may be used.
