BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is an apparatus for unhooking releasable snells from a main line when working with an automatic longline-handling machine. The apparatus will detach snell from a main line during hauling for separate storage of the main line and snell. The snell and main line are separated because it is suitable to store them in different places and easy to replace damaged snells with new ones.
2. Description of Related Art
When catching fish, different types of tools are used, which can be divided into two main groups. One group comprises catching where different kind of nets, such as a fishing net and trawl are used. The other group of catching tools comprises those where hooks are used. Further, one type of these are longlines with a main line and in suitable distances along this snells, which can be hooked on and can be unhooked.
SUMMARY OF THE INVENTION
The snell is attached at right angles to the main line by a swivel which makes it possible to rotate around its own lengthwise axis. This makes the snell and hook rotatable around the lengthwise axis of the main line. The connection between snell and swivel may either be cut off or may be hooked on to the main line and can be unhooked by hand or by machine.
The hook/swivel-equipment which this invention is working with, is shown in FIG. 1. A swivel 3 consists of a cylindric part 37 which is free to move between two stoppers 2 which further are permanently attached to the main line 1 at a predetermined distance from each other. On the middle of the cylindric part of the swivel, an eye 4 is attached to a partly S-shaped hook 6 which is further connected to the snell. This hooking equipment prevents the snell from rotating around its own length axis. The snell is hooked off/on to the main line by hand.
The intention of the invention is to unhook the snell in a very short time and in a secured manner.
This is achieved by use of an unhooking bar which to its end is attached a needle which carries out the unhooking operation and is controlled by the running swivel. The needle keeps the unhooked S-shaped hooks a short while after they have been released from the main line. An arm shaped like a foot, kicks the hook into a store consisting of a rod.
BRIEF DESCRIPTION OF THE DRAWINGS
Further details according to the invention will appear throughout the claims and the following description of an embodiment, with references to the accompanying drawings.
FIG. 1 shows the unhooking equipment between the main line and the snell which this invention is based on;
FIG. 2 is a section along line II--II in FIG. 1;
FIG. 3 shows the unhooking unit when the swivel is in the first part of the unhooking operation where the swivel is in the process of coming into engagement with a component of the unhooking device;
FIG. 4 shows the unhooking unit when the snell is unhooked from the main line and is on its way into the store; and
FIG. 5 is a cross-section along line V--V in FIG. 3 through a guide rail. This is the last part of the unhooking operation.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The arrangement for attaching the snell 5 to the main line 1, is viewed in FIG. 1. On the main line 1 at a suitable distance from each other two stoppers 2 are arranged. In between these a swivel 3 is free to run. The swivel 3 consists of a cylindric part whereto the middle of its peripheral an eye 4 is situated. The main plane of the eye 4 is at right angles to the length axis of the main line 1, but this length axis does not fall into this plane. They are at right angles to each other. The opening of the eye 4 has a rectangular shape. The swivel also includes a cylindrical sleeve section 37 which is permanently connected to the eye 4 via a neck section 35.
The snell 5 is attached to the hook 6 of which one end is attached to the snell 5 and the other to a part shaped like half of an S. This we usually call a hook shape. The cross-section of the hook 6 is also rectangular to suit the eye 4. The hook 6 may be difficult to move
