The snap in the recess 6 is attached to the main rope between the arms 16 and 17 to connect the branch rope 5 to the main rope. after that,
When the base 18 of the rope handler 15 returns to the extension of the pulleys 14, 14 of the thrower 13 by the action of the cylinder 19 and releases the branch line, the fishing bait 7 is removed from the third pitch conveyor 3 via the chute 9. The arm 11 on which the fishing bait 7 is placed is rotated at high speed by the action of a spring (not shown) to throw the fishing bait 7 into the sea. Therefore, by repeating this action, the branch rope 5
The fishing baits 7 attached to the can be sequentially thrown into the sea.

However, in such a conventional longline inputting device, when the bundled branchline 5 is placed on the branchline placement section 4 on the first pitch conveyor 1, the branchline 5 comes apart due to the twist of the branchline 5 itself. However, the branch rope 5 may become loose due to the wind or being stirred by the wind.
If the branch ropes 5 come loose, the branch ropes 5 may become tangled or entangled with the first pitch conveyor 1, and there is a risk that the automatic work of setting the ropes will often be interrupted.

[Purpose of invention]

The present invention aims to provide a longline feeding device that overcomes the problems of the conventional devices mentioned above, eliminates the looseness of branch lines on the pitch conveyor, and enables stable automatic casting of ropes. purpose.

[Summary of the idea]

The present invention includes a pitch conveyor that sequentially conveys tied branch lines, and a feeder that automatically throws into the sea the fishing bait attached to a fishing hook connected to the tip of the branch line. In the longline feeding device, a pressing member for pressing the branch rope conveyed by the conveyor is disposed above the belt of the pitch conveyor along the traveling direction of the belt, and the branch rope is pushed by the pressing member. It is characterized by the fact that the branch ropes are conveyed while being pressed down to prevent them from coming loose, so as not to interfere with the automatic work of throwing ropes.
