DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net roller for forcibly stopping the rotation of a reel in an emergency when an operator is wound on the reel together with a fishing net. In particular, the present invention relates to a net roller that enables a worker caught on a reel by a fishing net to forcibly stop the reel while being caught.

[0002]

2. Description of the Related Art A bottom net or a batch net is wound by a net roller mounted on a fishing boat. The net roller is
To be able to wind up a fishing net that has captured several tons of fish,
It is rotated with an extremely strong winding torque. For example, netting net rollers generally rotate the reel with a take-up torque of 7 to 8 tons. When a fishing net is being wound on a reel rotated with an extremely high torque, an operator may be caught with the fishing net. In fact, a considerable number of workers are killed every year in this accident.

In order to prevent this accident, the net roller is provided with an emergency stop switch. The switch is provided on a frame that supports the reel. When a worker caught in the fishing net can operate this switch,
Emergency stop of reel rotation. However, when the worker cannot operate the switch, the rotation of the reel cannot be stopped, and the reel gets caught in the reel together with the fishing net and dies. The switch provided on the frame can be operated when the worker's hands or clothes are entangled and the feet are on the deck, but if the worker's feet are taken off and fall down, the frame switches Can not be reached by reaching your hand. In this state, the reel is caught together with the fishing net on a reel rotated with a torque of several tons, and furthermore, it is extremely strongly tightened by the fishing net which is wound one after another and dies.

[0004] In place of a switch for an emergency stop, a device for stopping the rotation of the reel by the voice of an operator has been developed.
This device detects a worker's voice and causes the reel to stop urgently. This device can prevent the operator from being caught on the reel together with the fishing net as long as it can be used normally.

[0005]

However, in a device for stopping a reel by the voice of an operator, the reel sometimes stops when it is unnecessary. For example, a radio device for communication is mounted on a fishing boat, and a reel may be stopped in an emergency by a voice of a speaker of the radio device. If the rotation of the reel stops due to a malfunction, the efficiency of the winding net work is significantly reduced. This fact has hindered the spread of this type of device. The device for emergency stop by voice can reduce malfunctions by setting the level of voice for stopping the reels to be high. However, if the voice level is set too high, it may not work properly when it gets caught. On the other hand, when the high level at which the reel is stopped is lowered, the number of malfunctions increases, and there is a disadvantage that the efficiency of the normal winding operation is reduced.

[0006] The present invention has been developed with a view to solving such a drawback. An important object of the present invention is to wind a fishing net on a fishing boat mounted on a fishing boat so as to prevent a malfunction in which the reel is stopped when it is not needed, and to be able to reliably stop the reel in an emergency when the worker is caught on the reel. It is in providing a net roller to take.

[0007]

A net roller mounted on a fishing boat of the present invention for winding a fishing net onto a reel comprises a reel 1 for winding a fishing net, a driving mechanism 2 for rotating the reel 1, and a driving mechanism 2. Has stopper means 3 for stopping the rotation of the reel 1.

[0008] The stopper means 3 comprises a rotating shaft 4 of the reel 1.
And a contact rod 6 disposed in parallel with the reel 1 and disposed above and near the reel 1.
And a limit switch 7 for detecting that a force has acted on the contact rod 6 or for detecting that the position has been moved, and outputting a signal. The output of the limit switch 7 controls the rotation of the engine. It stops the rotation of the reel 1 is stopped, and a holding mechanism 12 for holding the reel 1 in a stopped state. When the worker gets caught in the fishing net wound on the reel 1, the worker operates the contact rod 6 disposed above the reel 1. When the contact rod 6 stops the rotation of the reel 1 by the output of the limit switch 7, the rotation of the reel 1 is held in a stopped state.

The holding mechanism shown in FIG. 4 performs the following operation to forcibly stop the reel in an emergency. The worker who is taken by the fishing net and is wound on the reel 1 pushes the contact rod 6 by hand when passing over the reel 1 or moves the contact rod 6 when the body touches the contact rod 6. When the contact rod 6 is pushed, the movement of the contact rod 6 is transmitted to the plunger 11 of the limit switch 7 via the connecting rod 10, and the plunger 11 is displaced from the neutral position. In this state, the limit switch 7 outputs a stop signal and inputs it to the holding mechanism 12. When the stop signal to the holding mechanism 12 is inputted,
Hydraulic pump 15 is no longer rotated. Hydraulic pump 1
If the reel 5 does not rotate, the hydraulic motor 17 is not driven, and the rotation of the reel 1 is stopped.

[0021]

According to the present invention, the net winding device mounted on a fishing boat for winding a fishing net onto a reel reliably prevents a malfunction such as an emergency stop of the reel when it is not necessary, so that an operator can be wound on the reel. In an emergency, there is a feature that the reel can be reliably stopped and used extremely safely. This is because an operator who is wound on the reel together with the fishing net can reliably stop the reel by approaching the reel and reliably contacting the contact rod disposed above the reel. The contact rod disposed close to the reel makes contact with a part of the body such as the hand or foot of the worker who is wound on the reel together with the fishing net. The contact rod contacted by the worker is detected by the limit switch and a stop signal is input to the holding mechanism, and the holding mechanism forcibly stops the rotation of the reel. Furthermore, after the worker is caught on the reel and the reel is stopped,
The reel rotation is held in a stopped state until a normal state is reached and work can be performed safely. For this reason, when an accident occurs in which an operator is entangled in the reel, the reel is reliably stopped, and the reel can be used extremely safely, and an effect that can eliminate any fatal accident or the like is realized.
