DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a technique for repairing a yarn (hereinafter simply referred to as a yarn) to a fishing line or other similar yarn at a broken portion of a net. The present invention relates to a drive operation device of a fishing net repair machine for repairing in connection with a network.

(Prior art)

Generally, the repair of a broken net is performed by connecting one end and the other end of the technical thread to one of the broken yarns and the other of the broken yarns. Was performed inefficiently.

In recent years, a repair machine has been developed that performs this repair mechanically. This repair machine has a guide section that reciprocates a shuttle inside a bobbin wound with a technique thread, and an original thread that links the technique thread. And a building adapted to advance toward the guiding portion while rotating in a state in which the technical yarn unreeled from the bobbin in the shuttle is locked at two points, and then retract. The shuttle
The shuttle and the bill are configured to pass through the loop of the thread formed by the building, move forward to a position beyond the original thread insertion portion, and then retreat to the original position. By operating a lever, the rack piece is moved, and the rack piece is moved through a gear meshing with the rack piece.

[Problems to be solved by the invention]

Therefore, according to this type of repair machine, the grip yarn for operating the shuttle and the grip lever for operating the building are respectively operated in the order of the binding process, so that the yarn is tied and tied to the original yarn. If the operation procedure is incorrect, the related members may be damaged, and the original thread must be inserted from the original thread insertion part with the grip lever for operating the shuttle. There were also problems such as difficulty in removing.

[Means for solving the problem]

In view of this, the present invention provides a cam plate that is rotatably driven forward and reverse around a shaft fulcrum through a forward / reverse switching clutch mechanism by the power of a drive source. Interlocking with a building that can hook the technical thread drawn from the bobbin at two points, the cam plate is rotated in the forward direction while rotating the building from the cam plate side to form a loop of the technical thread. Along with moving forward, the shuttle passes through the loop of the technique thread, moves to a position beyond the original thread insertion portion for inserting the original thread that binds the technique thread, and switches the cam plate to the reverse direction. A fishing net repair machine configured such that the shuttle turns back and returns, and the building also retreats, wherein the forward / reverse switching clutch mechanism is operated by contact switching operation of a clutch operating member during rotation of the cam plate. A drive operating device of a fishing net repair machine in which a clutch disengaging member for automatically switching to a standing position is provided at an appropriate position on the cam plate. Two clutch disengaging members are provided on the cam plate, and the clutch operating member is replaced with one clutch disengaging member. To restrict the switching operation to the neutral position and the switching operation to the normal rotation position side to automatically stop the cam plate during normal rotation, and to perform the contact switching operation to the neutral position with the other clutch release member, and , A drive operation device for a fishing net repair machine configured to automatically stop a cam plate during reverse rotation by restricting a switching operation to a reverse rotation position side,
This has solved the problem.

[Action]

By taking the above means, when the shuttle is in the original position, the forward / reverse switching clutch mechanism is switched from the neutral position to the forward rotation position by the clutch operating member to drive the cam plate in the forward direction. First, the building moves forward while rotating the building from the cam plate side in the radial direction, and furthermore, while feeding the yarn from the bobbin, thereby forming a loop of the yarn. Next, when the shuttle passes from the original position together with the bobbin in the loop of the technique thread, a knot is formed in the middle of the technique thread, and further, when the folding position is reached, the clutch operating member is disengaged by the clutch release member. The contact switching operation automatically switches to the neutral position, and the cam plate stops. Next, when the main thread is inserted from the main thread insertion section at this stop, the clutch operating member is switched to the reverse position and the cam plate is driven to rotate in reverse. Then, the clutch operation member is switched back and forth by the clutch disengagement member to automatically switch to the neutral position, and the cam plate stops. Then, during this time, the artificial thread unwound from the shuttle goes around the original thread and then passes through the loop to return to the original thread, so that the original thread is taken into the knot and the artificial thread is tied to the original thread. You can do it.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a fishing net repair machine includes a driving unit 3, a cam plate 4 driven by the driving unit 3, and a building 5 driven by the cam plate 4 in a case 1 having a grip unit 2. And a shuttle 6, etc., which are the main components.

The case 1 is composed of a main body case 7 having a grip portion 2 and an upper case 8 and the like attached to the upper wall of the main body case 7, and houses the building 5, the shuttle 6, etc. in the main body case 7. The drive unit 3 and the cam plate 4 are housed in 8. A main thread insertion portion 9 for inserting one main thread A1 of the torn fishing net A or the other main thread A2 (see FIG. 12) of the torn fishing net A traverses a guide portion 39 described later. On the outer surface of the lower wall of the main body case 7, a thread presser piece 10 for holding an end of a technique thread B fed from a bobbin 37 described later is attached.

The drive unit 3 uses a forward / reverse switching clutch mechanism to transfer the power of the motor 11
The transmission is transmitted to the cam plate 4 via the gear transmission mechanism having the gear 12, and the switching operation of the forward / reverse switching clutch mechanism 12 is performed by the clutch operating member 26 to rotate the cam plate 4 forward and backward. The gear transmission mechanism meshes a large gear 16 with an output gear 15 attached to an output shaft 14 of the motor 11, and integrally attaches a transmission gear 18 and a clutch drum 19 to a mounting shaft 17 of the large gear 16. The mounting shaft on which the planetary movable clutch gear 20 is mounted in mesh with this is mounted on the clutch drum.
The clutch gear 20 is housed together with the spring 21 in a storage hole formed in the housing 19, and the clutch gear 20 is pressed against the upper surface of the large gear 16 by the spring 21 so that the clutch gear 20 is rotated in the rotation direction of the large gear 16. The forward rotation gear 22 and the reverse rotation gear 23 meshing with the forward rotation gear 22 are supported at positions where the clutch gear 20 can mesh with the planetary position change, and the driving gear 24 meshed with the cam plate 4 is rotated forward. Attached to the diversion gear 22 shaft.

As shown in FIG. 3, the forward / reverse switching clutch mechanism 12 is provided at the upper, middle, and lower positions on the outer peripheral surface of the clutch drum 19, and at positions where the circumferential phase is appropriately shifted. And one reversing claw 19c is protruded, and one of the swinging ends of a clutch lever 26a having a halfway pivoted up and down so as to be able to swing up and down is brought into contact with the claws 19a, 19b,
The upper and lower positions can be changed in each step of 19c, and the other swinging end faces near the upper surface of the cam plate 4. And
An operation lever 26b attached to an appropriate position of the clutch lever 26a is engaged with a changeover switch 26c, and the changeover switch 26c is provided on the main body case 7 so as to be slidable up and down, and these members 26a to 26c
To form the clutch operating member 26 (although the operating lever 26b may directly protrude from the upper and lower holes of the main body case 7). As a result, when the clutch operating member 26 is switched from the normal rotation position F to the neutral position N below and further to the reverse rotation position R, the swinging end of the clutch lever 26a on the clutch drum 19 side moves the forward rotation claw 19a of the clutch drum 19 It is moved from a certain upper stage to a middle stage with the neutral nail 19b, and further moved to a lower stage with the reversing nail 19c. When the swing end is at the upper position of the clutch drum 19,
Until the forward pawl 19a of 19 engages with its swinging end, the large gear 16
The clutch drum 19 is rotated along with the clutch gear 20 pressed against the same in the same direction as above, and at the time of engagement, the clutch drum 19 stops and at the same time the clutch gear 20 meshes with the forward rotation gear 22 (first (Refer to the chain line in the figure)), motor
The power 11 is transmitted from the output gear 15 to the cam plate 4 through the large gear 16, the transmission gear 18, the clutch gear 20, the forward rotation gear 22, and the drive gear 24, and the cam plate 4 is moved in the direction of the arrow in FIG. It will rotate forward. Similarly, when one swing end of the clutch lever 26a is switched to the middle position of the clutch drum 19, the clutch drum 19 is rotated until the neutral hook 19b of the clutch drum 19 engages with the swing end, At the time of engagement, the clutch drum 19 stops, and at the same time, the clutch gear 20 enters a neutral state in which it does not mesh with either the forward rotation gear 22 or the reverse rotation gear 23, so that the power of the motor 11 is not transmitted to the cam plate 4. Further, when one swing end of the clutch lever 26a is switched to the lower position of the clutch drum 19, the clutch drum 19 is rotated until the reversing claw 19c of the clutch drum 19 is engaged with the swing end. When the clutch drum 19 is stopped at the time of engagement, the clutch gear 20 is engaged with the reverse rotation gear 23 at the same time (see the dotted line in FIG. 1), so that the power of the motor 11 is transmitted from the output gear 15 to the large gear 16, Gi 18,
Clutch gear 20, reverse rotation gear 23, forward rotation gear 22, drive gear 2
The light is transmitted to the cam plate 4 via 4, and the cam plate 4 rotates in the reverse direction. At this time, the cam plate 4 is connected to the clutch operating member 26.
Is switched from the neutral position N to the normal rotation position F, so that the clutch operation member 26 is rotated forward by about 180 ° from the position, and then the clutch operation member 26 is automatically returned to the neutral position N and stopped. By switching the clutch operating member 26 from the neutral position N to the reverse rotation position R, the clutch operation member 26 is configured to reversely rotate and return to the original position. The specific configuration is that a first L-shaped clutch disconnecting member 27 protrudes from the upper surface of the cam plate 4 where the other swinging end of the clutch lever 26a is located. The swing end of the clutch lever 26a faces the space between the upper surface of the cam plate 4 and the outer peripheral side of the cam plate 4, and furthermore, restricts the vertical swing, so that the neutral position N moves upward and the forward rotation position moves downward. Only the operation of the clutch lever 26a with F is permitted (actually, the cam plate 4 rotates in the reverse direction and the swinging end of the clutch lever 26a comes into contact with the clutch disengaging member 27 so that the clutch disengaging member 27 The clutch lever 26a is automatically returned to the neutral position N because the lower surface is brought into contact with the lower surface, and the clutch lever 26a automatically returns to the neutral position N). A second clutch release member 28 having a convex shape is protruded,
As a result, the swinging end of the clutch lever 26a rides on the clutch disengagement member 28 from the upper surface of the cam plate 4 which has been normally rotated in contact with the clutch lever 26a, automatically returns to the neutral position N, and stops immediately. The operation of the clutch lever 26a from the side to the reverse rotation position R is permitted.

The cam plate 4 is provided with gear cutting on the outer peripheral surface of the disk, and the above-mentioned first and second clutch cutting members 27 and 28 are provided on the upper surface side.
On the lower surface side, a substantially semi-circular building cam groove 29 and a substantially semi-circular shuttle cam groove 30 are cut away so as not to overlap with each other. It is fixed to a longitudinal axis 31 that is rotatably supported.

The shuttle 6 has a substantially rectangular shape having both ends of a rectangular body tapered (conical shape). The shuttle 6 has a rotatable bobbin 37 wound with a technique thread B, and a hook 38 formed at a rear end. Have been. The shuttle 6 is guided in a substantially crescent-shaped guide portion 39 formed between the outer peripheral wall of the main body case 7 and the central support 32 and between the upper wall and the lower wall of the main body case 7. It is housed so as to be reciprocally slidable along the portion 39. For reciprocation of the shuttle 6, an arm 41 is fixed to a lower end of a rotating shaft 40 rotatably mounted on the upper wall of the main body case 7, and a fitting pin 42 fixed to one end of the arm 41 is connected to the main body case 7. 7
It fits into the shuttle cam groove 30 of the cam plate 4 through the hole in the upper wall, and has a U-shaped hooking piece 43 which is resiliently elastically attached outward and attached to the other end. The piece 43 is hooked and connected to the hook 38 of the shuttle 6 so that when the cam plate 4 rotates in the forward direction, the arm 43 is inserted through the fitting pin 42 that slides along the shuttle cam groove 30. The shuttle 41 is rotated by the hook 43 and the shuttle piece 43 is rotated by the hook piece 43 to move the shuttle 6 from the original position to the position beyond the original thread insertion section 9 along the guide portion 39. Then, the shuttle 6 reaches the turning position (FIG. 5), and at the time of reverse rotation, the shuttle 6 similarly slides and returns to the original position (FIG. 6).

Therefore, the overall layout is such that the cam plate 4 is located above the substantially central portion of the main body case 7 and the building 5 is located in the lower front-rear direction.
A drive system such as the drive unit 3 having one motor 11 is arranged on this side, and the battery 44 is stored in the grip unit 2.
Since the changeover switch 26c of the clutch operating member 26, the power switch 45, and the like are arranged at or near the grip portion 2, the weight and the size are reduced, the handling is improved, and the center of gravity of the machine can be used by one hand. There are advantages such as closer approach and improved operability.

The upper case 8 contains the components shown in FIGS.
As shown in the figure, one end of a shaft portion 47a rotatably supported by a support member 46 is bent at a right angle, the tip of the bent portion is curved in an arc shape to form a holder portion 47b, and the other end is formed. A yarn holder 47 that is bent in a crank shape to form a crank portion 47c is provided. The thread holder 47 is configured such that the holder portion 47b is moved from the upper case 8 to the building 5 and the shuttle 6 in the main body case 7.
It is possible to move in and out of the movement trajectory of
As shown in FIG. 10, at a predetermined time (during reverse rotation of the cam plate 4), an operation piece 49 that rotatably supports the pin 48a of the arm 48 rotatably supported on the support member 46 on the upper surface of the cam plate 4. Rotation restricting piece 46a
This is done by rotating the crank part 47c of the thread holder 47 to the position shown by the two-dot chain line in FIG. As shown in FIG. 11, the pin 48a of the arm 48 is controlled to rotate at a predetermined time (at the start of normal rotation of the cam plate 4) by a return piece 50 rotatably supported on the upper surface of the cam plate 4, as shown in FIG. By pushing back to the piece 46b, the crank portion 47c which has been slid down to the lower surface is released, and is automatically returned to the original position by the return spring 51. At this time, the operation piece 49 and the return piece 50 are urged to the positions of the stoppers 52 and 53 projecting from the cam plate 4 by relief springs (not shown). The pin 48a of the arm 48 pushed back is passed through the tunnel and escapes. The arm 48 and the pin 48
a is a height relationship that does not interfere with the first and second clutch disengaging members 27 and 28.

In the figure, reference numeral 54 denotes a shuttle insertion hole for inserting and removing the bobbin 37 from the outside to the guide portion 39, and reference numeral 55 denotes an end of the technical thread B wound out from the bobbin 37 to the outside, and Yarn guide slit, 5 which makes it easy to hold
Reference numeral 6 denotes a bobbin gear rotating integrally with the bobbin 37, 57 a bobbin gear transmission mechanism for transmitting the power of the motor 11 to the bobbin gear 56, 5
7 is a yarn winding clutch substantially similar to the forward / reverse switching clutch mechanism 12,
Reference numeral 58 denotes a return pin for manually returning the arm 48.

According to the above, first, the technique yarn B unwound from the bobbin 37 in the shuttle 6 inserted into the guide portion 39 is inserted into the locking groove 5b of the building 5.
The main thread insertion section 9 is passed through the thread guiding slit 47 while being
And the end of the technique thread B is held by the thread presser 10 of the main body case 7.

Next, after turning on the power switch 45 and operating the motor 11,
When the clutch operating member 26 is switched from the neutral position N to the forward rotation position F, the clutch gear 20 is engaged with the forward rotation gear 22, and as a result, the cam plate 4 is rotated forward and the second clutch disengaging member 28 is rotated. When the clutch lever 26a comes to the swing end position of the clutch lever 26a, the clutch lever 26a automatically returns to the neutral position N, so that the clutch gear 20 moves away from the forward rotation gear 22 until the clutch gear 20 becomes neutral, and the cam plate 4 Stops. During the normal rotation of the cam plate 4 during this time, first, the return piece 50 pushes back the pin 48a of the rotating arm 48 and retreats the holder portion 47b of the thread holder 47 that has advanced into the guide portion 39. After that, the fitting pin 35 fitted in the cam groove 29 for the building,
Via the fixing pin 36 engaged with the shaft groove 5c of the building 5,
The bill 5 moves forward toward the guide portion 39 while rotating to the set angle and stops, with the thread Y being locked at two points as shown in FIG. (At this time, the opposite locking groove 5d is in the vertical position (see FIG. 5), and the shuttle 6 is allowed to pass.
A loop B1 of the technique thread B through which the shuttle 6 can pass is formed in the middle of the technique thread B as shown in FIG. 8). The shuttle 6 stops at the turnover position through the mating pin 42 in the U-shaped piece 5b of the building 5 and in the loop B1 of the technique thread B and beyond the original thread insertion section 9 (FIG. 5). ). As a result, a knot B2 is formed in the middle of the technique thread B as shown by the solid line in FIG. Then, as shown in FIG. 5, one of the main threads A1 of the broken portion of the fishing net A is inserted into the inner part of the main thread insertion section 9, and at this time, the main thread A1 is hooked into the hook piece. By pressing against the spring 43, the hook 43 pressed against the spring force comes off the hook 38 of the shuttle 6, allowing the insertion of the original thread A1. Shuttle 6 hook
Hanged on 38.

When the clutch operating member 26 is switched from the neutral position N to the reverse rotation position R, the clutch gear 20 is moved to the reverse rotation gear 23.
As a result, the cam plate 4 is reversed, and when the swing end of the clutch lever 26a comes into contact with the first clutch release member 27, the clutch lever 26a automatically returns to the neutral position N and the clutch The gear 20 moves away from the reverse rotation gear 23 to a neutral state, and the cam plate 4 stops. During the reverse rotation of the cam plate 4 during this time, the shuttle 6 returns to the original position as shown in FIG. Thread B is fishing net A
After wrapping around one of the original yarns A1, as shown in FIG. 9, the knot B2 returns to the knot B2 in the middle of the artificial yarn B. Immediately after this, the holder portion 47b of the artificial yarn B wound around the building 5 The engineering thread B is advanced into the loop B1 (see the two-dot chain lines in FIGS. 6, 7 and 9), and the building 5 retreats while rotating backward to the set angle and winds around the building 5 Is securely removed by the holder part 47a, and then returned to the original position.

Next, by switching the winding clutch 50 of the bobbin transmission mechanism 49 from the neutral position N to the takeup position G with a manual lever (not shown), the power of the motor 11 is transmitted to the bobbin gear 48 through the bobbin transmission mechanism 49. By being transmitted, the bobbin 37 is rotated in the winding direction of the technique thread B, and the technique thread B is tightened, and the technique thread B is tied to the original thread A1 at the position of the holder portion 47a. , You can unite in the same place. Then, the arm 48 is returned by manually operating the return pin 58, whereby the holder portion 47a is retracted and removed.

In the above manner, as shown in FIG. 12, the technique yarn B tied to one of the yarn A1 of the broken portion of the fishing net A is now replaced with the other yarn A2 of the broken portion of the fishing net A. In this case, the broken portion of the fishing net A is repaired. At this time, since the binding position is known in advance by the thread holder 47, the position of the technique thread B held by the thread holding piece 10 is determined. By determining, the size of the mesh can be fixed.

In the above description, the motor 11 is used as a drive source.
14 is protruded from the main body case 7, the rack piece is engaged with the gear fixed to this protruding portion, and this rack piece is connected to the main body case 7 by a grip lever which is pivotally supported. The gear may rotate through the piece to drive the output shaft 14. At this time, the output shaft 14
However, it is preferable to incorporate a one-way clutch at any point in the transmission path from the grip lever, which can be returned by an elastic force, to the output shaft 14 so that it always rotates in one direction.

〔The invention's effect〕

As described above, according to the present invention, the power of one drive source 11 is
, And can be transmitted to the building 5 and the shuttle 6 and these two systems can be driven. Therefore, the size can be reduced as compared with a system having two driving sources for driving the building 5 and the shuttle 6, respectively. Further, since the cam plate 4 is rotated forward and backward, the cam groove 29 for the building and the cam groove 30 for the shuttle are
Building 5 and shuttle 6
Can be operated by one cam plate 4, and the structure can be simplified. Further, a clutch release member 28 is provided on the cam plate 4, and the forward / reverse switching clutch mechanism 12 is automatically switched to the neutral position N by the clutch release member 28 at the turn-back position of the shuttle 6, and the cam plate 4 stops. The work of inserting the yarn A1 into the main yarn insertion section 9 can be easily performed, and the work efficiency is improved. further,
Two clutch disengaging members 27 and 28 are provided, and the clutch operating member 26 is controlled by the one clutch disengaging member 28 to switch the contact to the neutral position N and to restrict the switching operation to the forward rotation position F to correct the clutch operation. Automatically stop the cam plate 4 during rotation, and use the other clutch release member.
27, when the contact switching operation to the neutral position N and the switching operation to the reverse rotation position R are restricted so that the cam plate 4 during the reverse rotation is automatically stopped, the clutch operating member 26 is connected to the binding process. The switching operation can be performed only in a direction suitable for the operation, and trouble such as damage to related members due to erroneous operation does not occur.
