Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a knotting machine for repairing a broken net, which repairs the net.

[Conventional technology]

Regarding this knotting machine for fishnets, the inventor of the present invention has a structure in which a bobbin case, in which a repairing yarn is wound inside a loop of the repairing yarn, advances and retreats to form a knot, as disclosed in Japanese Patent Application No. 63-290567.
(See Japanese Patent Publication).

[Problems to be solved by the invention] With such a configuration, since it is necessary to take a complicated structure in which the bobbin case is moved back and forth on a circular orbit, reliable operation is difficult and costly. In addition, the output of the drive motor and the like is unexpectedly large, which is not preferable in terms of weight and price.

The present invention is intended to solve such a problem, and an object thereof is to provide a knotting machine having a minimum number of moving parts and ensuring a reliable operation. And
There is a cheap and reliable way to input the drive source.

[Means for Solving the Problems]

That is, in this invention, the repair yarn unwound from the bobbin housed in the bobbin case is wound around a rotatable building provided at a position opposite to the bobbin case, and stopped again in a holder provided on the bobbin case side. A repairing yarn loop mechanism that rotates the building to loop the repairing yarn while being wound around the building, and a fish net to be repaired is hooked by a needle capable of advancing and retracting inside the building to pass through the loop. A fishnet threading mechanism to be released so as to pass under the bobbin case when it comes off the loop,
A knotting machine for repairing a fish net, comprising a repairing yarn drawing mechanism for forcibly rotating the bobbin to squeeze the loop of the repairing yarn passing through the fish net to be repaired.

In addition, in the above-mentioned configuration, a knotting machine for repairing a fish net is proposed, in which the repairing yarn loop mechanism and the fish net threading mechanism to be repaired are actuated by the gripping force of the grip, and the repairing yarn drawing mechanism is actuated by the turning force of the lever. Is.

[Action]

By taking the above means, the repair thread loop mechanism only rotates the bobbin around its bobbin axis, and the repaired fish net threading mechanism only moves the needle forward and backward, and further, the repair thread drawer Since the mechanism only forcibly rotates the bobbin, its operation is simple and malfunctions are unlikely to occur. In addition, since the power source of each mechanism is human-powered, inexpensive and light-weight ones can be realized.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 9 are plan view, front view, and 10 of the knotting machine for repair.
The figure is a perspective view showing a knotting state. This knotting machine is composed of the following repair yarn loop mechanism 1, repaired fish net threading mechanism 2 and repair yarn drawing mechanism 3.

First, regarding the repair yarn loop mechanism 1, a bobbin 6 housed in the bobbin case 5 on one side of the tip of the main body case 4, a holder 8 for stopping the repair yarn 7 unwound from the bobbin 6, and further this A building 10 and the like, which are provided at opposite positions of the bobbin case 5 and are rotatable around the building shaft 9, are provided. As a result, the repair yarn 7 unwound from the bobbin 6 is stopped by the holder 8 while being wound around the building 10 half-circle, and one rotation operation of the building 10 around the building shaft 9 causes the repair yarn 7 to loop. Will be configured.

Next, regarding the fish net threading mechanism 2 to be repaired, the locking portion 11 is attached to the tip.
A needle 11 having a is provided so as to be able to move back and forth in the building 10. As a result, the needle 11 advances and hooks the fish net 12 to be repaired at its locking portion 11a, retracts within the loop of the repair yarn 7 and stops near the end of the bobbin case 5. Then, the fish net 12 to be repaired is released and falls to the lower side of the bobbin case 5.

Further, the repair yarn drawing mechanism 3 is a clutch structure in which a lever 13 that is manually operated and a power connection for forcibly rotating the bobbin 6 through a one-way clutch 14 for a one-way rotation operation of the lever 13 are used. It is composed of 15 mag. When the bobbin 6 is forcibly rotated, the loop of the repair yarn 7 that passes through the fish net 12 to be repaired is squeezed and knotted here.

By the way, the rotation of the building 10 and the advance / retreat of the needle 11 are also operated manually. That is, a grip 16 which is grasped and has a small diameter is provided at a rear portion of the main body case 4, and a pantograph 17 which is advanced toward the tip side when the grip 16 is contracted is provided, and the needle 11 is connected to the pantograph 17. Further, a lever 18 is provided at the rear of the needle 11, and a gear structure 20 for rotating the slider 19 and the bill shaft 9 is provided in front of the lever 18. This allows the grip
When grasping 16 and moving pantograph 17 forward, needle 11
In addition to moving forward, the lever 18 and slider 19 also move forward to rotate the gear structure 20 and rotate the building 10 around the building shaft 9 once.

Explaining the case of repairing the fish net 12 to be repaired using the knotting machine having the above configuration, first, the repair yarn 7 is unwound from the bobbin 6 and wound around the building 10 and then fixed to the holder (first
(Fig. 2, Fig. 2). Next, while gripping the grip 16 (Fig. 3) and rotating the building 10 by 360 ° (Fig. 4), the needle 11 is passed through this, and when the needle 11 protrudes inside the building 10, its locking portion. Hook the portion of the fish net 12 to be repaired that is to be knotted on 11a (Fig. 5). Furthermore, the grip
When the needle 16 is released, the needle 11 retracts inside the building 10 while hooking the fish net 12 to be repaired, and stops at the normal position (the locking portion 11a is a position behind the bobbin case) (Fig. 6).
The fish net 12 to be repaired is released from the locking portion 11a and falls behind the bobbin case (Fig. 7). At this time, the bobbin case 5 is moved by the spring 21 so that the fish net 12 to be repaired falls completely behind the bobbin case 5.
It is pressed to the side so that there is no gap between the bobbin case 5 and the needle 11. Repair yarn 7 is a needle
If it is released from 11, the fish net 12 to be repaired is pulled forward by hand and completely passed under the bobbin case 5 to approach the loop of the repair yarn 7, but at this time, the repair yarn 7 is also from the building 10. It comes off. Further, the lever 13 is operated (Fig. 9), the clutch structure 15 is driven, and the bobbin 6 is rotated (Fig. 8) to squeeze the loop of the repair yarn 7 wrapping the fish net 12 to be repaired, and knot it here. This is done (Fig. 10). Then, this operation is performed on the knotted portions one after another, and necessary repairs are performed.

[Effect of device]

As described above, the present invention is as described above, that is,
Since it has only a few moving parts such as the linear movement of the needle 11 and the rotation of the building 10 and the driving of the bobbin 6, the structure is simple and there are few malfunctions.
In addition, since the driving source is also based on human power such as grasping the grip 16 and turning the lever 13, it is lightweight and inexpensive,
And the operation is reliable. Furthermore, specifically, building 10
Is provided in the center of the front surface, it is easy to engage and disengage the repair yarn 7, and the needle 11 projects in the center of the front surface.
It is easy to hook the fish net 12 to be repaired, and bobbin case 5
Is installed below the building 10 and the needle 11, it has the advantage that it can be used even when it is turned upside down.
