Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a device for automatically detecting entanglement of trunk ropes that occurs when the lifted ropes are stored in a storage box.

[Prior art]

In the longline lifting work, the trunk rope lifted by the line hauler is separated from the branch ropes, superposed on the transfer conveyor in the form of a coil and transferred, and then transferred by a storage machine via guide pipes, guide rollers, etc. It will be piled up and stored in the storage to prepare for the next lanyard.

[Problems to be Solved by the Invention]

However, the trunk ropes to be hoisted were piled up in a coil on the transfer conveyor, transferred and sent out from the lower part, and the connection of the trunk ropes and the twists on the trunk ropes in the sea caused entanglement. It is stored in the storage as it is, and there is a defect that the smooth line cannot be set the next time. Therefore, the crew is currently working on lifting rope work, paying attention to the occurrence of tangles in the trunks that are constantly stored, and when they find a tangle, they stop the storage machine and untangle it. It is extremely hard work to keep an eye on the storage work while discovering the tangle while hoisting a long long line that weighs 10 to 15 kg. In view of these circumstances, it is an object of the present invention to automatically detect the occurrence of entanglement when storing trunk ropes so as to save labor in longline lifting work.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a pair of opposed cylindrical upper and lower detection rollers to an intermediate part of a guide roller having V-shaped trunk rope guide parts provided at the front and rear, and the opposed parts guide the front and rear parts. It is provided so as to be positioned below the straight line connecting the upper trunk line guide portion of the roller, and the upper detection roller is supported by a swing lever so as to be movable up and down, and the detection piece provided on the swing lever is attached to the upper detection roller. It is designed so that it can be brought close to the operation switch that stops the trunk rope storage machine when it is lifted. The operation switch uses a proximity switch and a limit switch.

[Action]

The trunk rope that has been hoisted passes from the upper part of the front guide roller between the pair of upper and lower detection rollers and is transferred to the storage box through the upper part of the rear guide roller, but if the trunk rope is entangled, Due to this entanglement, the upper detection roller is lifted upward, and by this lifting action, the detection piece provided on the rocking lever comes close to the operation switch and operates it to stop the storage machine and transfer the trunk rope. It is to remove the tangle and drive the storage machine again to store the trunk rope.

【Example】

The trunk A, which is hoisted by the line hauler 2 installed on the hull 1, is superposed and transferred in a coil shape on the transfer conveyor 3 as is well known, and then guided by the guide pipe 4, the guide roller 5, etc. It is configured to be transferred by the storage device 7 via the device 6 and can be stored in the storage case 8. The front guide roller 9 and the rear guide roller 1 having V-shaped trunk rope guide portions are provided at the front and rear positions of the guide device 6.
0 and a pair of upper and lower cylindrical detection rollers 11 and 12 whose opposing portions are located below the straight line connecting the upper trunk rope guide portions of the front and rear guide rollers are provided in the middle portion thereof. The roller 11 is rotatably supported by a swing lever 15, 15 supported by a support frame 13 via a shaft 14, and the rear portion of the upper detection roller 11 of the swing lever 15, 15 is adjustable. Support rod 16 ・ 16
And a detection piece 17 is attached to the lower side of the shaft support portion of one of the swing levers 15.
Pulls the upper detection roller 11 downward by the springs 18 and 18 provided between the support frame 13 and the upper detection roller 11 when the upper detection roller 11 is lifted upward against the springs 18 and 18. Reference numeral 17 is configured to rotate together with the rotation of the swing levers 15. Further, an operation switch 19 such as a proximity switch or a limit switch for controlling the storage device 7 is provided at a rotational position of the detection piece 17 when the upper detection roller 11 is lifted, and the upper detection roller 11 is stored when the upper detection roller 11 is lifted. It is configured to stop driving the machine 7. In the figure, 20 is a cushioning rubber member provided on the lower end of the support rod 16, and 21 is a guide cover for the front and rear guide rollers 9 and 10. Therefore, after adjusting the lengths of the support rods 16 and 16 so that the intervals between the upper and lower detection rollers 11 and 12 facing each other are substantially matched with the thickness of the trunk rope A, the trunk rope A is set on the upper part of the front guide roller 9 by V. The trunk rope A is guided to the storage machine 7 through the V-shaped trunk rope guide portion above the rear guide roller 10 from the letter-shaped trunk rope guide portion between the upper and lower detection rollers 11 and 12, and the trunk rope A is stored in the storage case 8. When the entangled portion A ′ of the trunk rope A passes between the upper and lower detection rollers 11 and 12 in such a state, the upper detection roller 11 is lifted by the entangled portion and the swing lever 15 and
The detection piece 17 rotates together with the rotation of 15 to rotate the operation switch 1
9 is operated to stop the storage machine 7 to stop the transfer of the trunk rope A to release the entanglement A ′, and the storage machine 7 is driven again to store the trunk rope A.

【The invention's effect】

According to the present invention, in a portion where a trunk rope that has been lifted is transferred to a storage box, front and rear guide rollers having a V-shaped trunk rope guide portion keep the direction of the trunk rope constant and smoothly guide the entanglement. It is possible to prepare for the next lanyard by securely sandwiching it between a pair of opposing upper and lower cylindrical rollers, automatically detecting this, stopping the transporting action of the trunk rope, untangling it and storing it in the storage box. As a result, unlike the conventional case, it is not necessary to always find out when a worker keeps watch during the hoisting work, and therefore the hoisting work can be omitted and the operation efficiency can be improved.
