Description

  The present invention relates to a net processing apparatus used for netting a lathe used for a lathe main vessel.

  In the harp fishery, nets thrown for fishing are rolled up as soon as the bottom is closed, but the nets that have been lifted must be laid on top of the platform in order to prepare for the next throwing net. I must.

  This work is extremely important for carrying out a quick net when the next school of fish is discovered. Therefore, a large number of workers are in charge of the netting work.

  The net lifted from the sea is first pulled by a net holer installed at the stern, and then pulled to a higher position by a netting machine suspended at the tip of a derrick boom or marine crane. It is dropped on the table in a free fall state.

  The net that comes down at this time is manually sorted by the worker's manual separation between the scorpion side located at the bottom of the bottom of the net and the float side at the top of the sea surface, and the middle part of the net is squeezed back and forth. Fold it over and store it on the screen.

  However, this netting operation is more difficult and difficult to perform on a ship that constantly swings and is more dangerous than expected.

  In other words, when a net of several tens to hundreds of meters is lifted from the sea, it folds as soon as possible evenly on a screen that is less than 10 meters, so it can be wet. Therefore, there is a considerable sense of weight, and it is forced to perform extremely severe work that requires considerable power by hand.

  In addition, since it is forcibly lowered from the netting machine held at a high position, it is necessary to continue the work while always supporting the body so as not to be squeezed by the net on a swinging ship.

  During stormy weather etc., the net body swings violently, and the body is often swung around by the inertial force of the net that shakes greatly while holding the net.

  If the lifting net goes further, you have to keep riding the rope on the stacked net, and it is often caught on a net or a foot on a soft net, which is quite dangerous and requires force It is a work, so many workers must be assigned.

  In recent years, floating traction devices and sewage traction devices have been developed and used to wind the floating and sinking portions of the net while pulling them, which has reduced the workload. The present situation is that the work of the middle net located between the children depends on the hands of the workers.

  In addition, a netting device has been developed to assist the operation of rolling and storing a net that has been lifted, but it has not yet been more effective than the manual work of workers.

Means to solve the problem

  In order to solve the above-mentioned problems, when observing the current lifting net work, the net coming down from the high-level netting machine is twisted or twisted, so that the worker is always on that net. The net is loosened while giving vibration.

  If you look closely at the movement, it will continue to give vibrations as if you were hitting the net while shaking it back and forth while shaking the net and shaking it left and right.

  The present invention observes and examines the movement that the worker gives to the net during work as described above, gives the same movement as the operation of loosening the net while giving vibration while hitting the net, and combing the net that has come down Therefore, the following configuration is adopted.

  A net that can be moved on rails that are optimally formed on both sides of the hull at the rear of the hull, and that can be moved up and down independently on both the left and right sides. Wear a whispering device.

  The net descending from a netting machine suspended on a derrick crane or the like is pushed and pulled so as to hit the net surface using the netting device, and is swung up and down and left and right. It is formed so that it can be accommodated while spreading in the lateral direction while removing the twist, and this method can be used to distribute the vastly wider than the hull width almost evenly, so that the net can be stored neatly on the platform It is composed.

The invention's effect

  As described above, the present invention compulsorily imparts the same vibration to the net as a conventional manual work by using a hydraulic power or the like for the work of netting that requires a large number of workers and is dangerous. At the same time, it is possible to improve work efficiency and contribute to labor saving and improvement of safety of lifting net work.

  Furthermore, since the netting work that has so far only relied on the manual work of many workers can be rationalized by mechanization, the work can be modernized.

  In addition, because the net that comes down from the netting machine is forcibly and towed, it is possible to set the position of the netting machine that had been raised to a very high position so that the center of gravity of the hull The position can be set low, and as a result, the balance of the hull can be stabilized, contributing to the improvement of the safety of the entire ship engaged in fishing.
