Description

[Detailed explanation of the idea] The present invention relates to an improvement of a longline winding device.

In the tuna longline fishery, the dry line is guided and guided by a side roller on the side of the boat and hauled in using a line hauler, but sometimes the branch line becomes tangled with the main line due to currents or other causes. The current situation is that the fishing line is pulled in such a way that the hook at the tip is bouncing up, which is extremely dangerous to the workers operating the line hauler.

In this case, if one pays close attention to the main line being hauled, it is possible to detect this and prevent danger, but it is extremely difficult to monitor as many as 3,000 branch lines for long periods of time during each operation. However, the reality is that due to lack of attention, this is often overlooked and the work of operating the line hauler is damaged.

The present invention is designed to prevent such accidents by installing a branch rope detector having a buffer spring at the base and protruding above the side roller located at the front of the line hauler. The gist is that a limit switch was installed that turns off the line hauler's driving power when the rope detector is activated.

To explain the embodiment of the present invention with reference to the drawings, a mounting base 1 mounted on the side of the line hauler is equipped with a pair of large and small vertical rolls 2 and 3 and a horizontal roll 4 located below the front of the mounting base 1. A support frame 6 attached to one side of the mount 1 is provided with an elliptical steel wire 7 located above the vertical rolls 2 and 3 and a buffer provided at the base thereof. A branch line detection device 9 formed by a coil spring 8 is provided protrudingly,
A limit switch 10 for turning off the driving power of the line hauler is provided on the support frame 6 at the protruding part of the branch rope detector 9, and when the branch rope that jumps up hits the steel wire 7, the branch rope detector 9 activates the limit switch 10. The line hauler is configured to operate to stop the hoisting action of the line hauler.

Since the embodiment of the present invention is constructed as described above, the main line of the longline is guided and guided from the sea by the side rollers 5 and hoisted by the line hauler.
During this rope hoisting operation, when the branch line becomes entangled with the main line due to current or other causes and is lifted by the side roller 5, the branch line hits the branch line detector 9, which activates the limit switch 10 to stop the line hauler. This is to notify the workers of the danger, and to correct the tangles in the branch ropes and continue the rope hauling work again.
In this case, the coil spring 8 buffers the impact of the branch rope and prevents the limit switch 10 from being damaged.

In the present invention, a branch line detection device with a buffer spring is installed above the side roller located at the front of the line hauler, and the branch line detection device operates a limit switch to turn off the drive power of the line hauler and line the line. The line hauler is now stopped, so if a branch line gets tangled with the main line and the fishhook jumps up when the line is pulled up, this can be detected immediately, the line hauler is stopped, and the worker is notified. It is possible to prevent the danger to workers due to the jump of the branch line, and also allows for efficient rope lifting work by straightening the tangle, and its structure is extremely simple and does not take up much space.It has excellent features and practicality. It has the following.
