Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a safety device for a longline hauler installed on a longline fishing boat.

``Prior art'' As is well known, fishing work in longline fishing involves dropping a longline consisting of a main line and branch lines into the sea via a throwing line machine installed at the stern of a fishing boat, and then fishing. Later, the longlines are hoisted up using a line hauler installed on the bow or aft deck of the bridge. /min) The branch ropes are carried onto a belt conveyor, where they are used to unhook and unhook branch ropes, or to check for damage to the ropes.
Alternatively, mainline processing work such as twisting and retangling is performed. The treated mainline is passed through guide rollers, tension rollers, etc., and then spooled back onto the stern hauling reel, or a mainline feeder (winder) that feeds the mainline into the mainline hangar. ), the ropes are put into mainline hangars and reused.

The conventional longline fishing method is not a continuous process; the mainline is pulled up by a longline winding machine and cut one by one, and then placed on a long belt conveyor (line conveyor) along the deck on the gunwale side. ), it was used as if it were stored in a rope storage area located at the stern of the ship.

However, in recent years, this type of fishing work requires a lot of manpower and does not improve efficiency, so it has become necessary to use so-called continuous fishing methods, which allow the main line to be wound in a continuous state without separating it. Equipped with line reels and main line feeding machines, fishing work has become a continuous process. In this way, in the case of continuous fishing work using the continuous line reel or mainline reeling machine, the mainline hauled up by the longline reeling machine is
The fish must be guided smoothly to the stern hauling line reel or the mainline reeling machine, but this series of operations must be tailored to the speed of the mainline reeling process performed by the longline reeling machine. .
In particular, in the case of mainline processing using a hauling reel, the hauling reel often suddenly stops, moves, or changes the speed of the fishing gear conveyor depending on the processing status of the longline winding machine. Mainline handling work on a fishing gear conveyor that moves irregularly is difficult for workers to predict and is dangerous as accidents are likely to occur. For this reason, Jikko Sho 55-6298
As shown in No. 1, when the mainline is deployed on the fishing gear conveyor and the mainline is continuously pulled on the hauling reel used on a tuna longline fishing boat, the worker's hand becomes wrapped around the line. An automatic emergency stop device has been developed that automatically stops the hoisting of the fishing line reel in the event of a danger such as being caught, thereby preventing accidents from occurring.

However, in recent years, the use of winding reels as mainline processing machines has not only become extremely dangerous as mentioned above, but also requires large equipment and occupies a large amount of space onboard ships.
They are no longer used because they are heavy, expensive, and often break down.
Instead, it appeared as a mainline processing machine,
This is a convenient mainline feeding machine that feeds the mainline into an automatic mainline hangar. This mainline feeder has very little danger and is very efficient, so everyone has come to have it. As a result, mainline processing is no longer considered a dangerous task in the industry.

In recent years, accidents involving the operation of longline winding machines that carry out longline winding operations have become more of a focus in the industry.

In the first place, a longline hoisting machine hoists the mainline from the sea at high speed (Max 272m/min, 4.53m/sec) by a worker who operates an operating handle, and the main line is hoisted up from the sea at high speed (Max 272m/min, 4.53m/sec), and the main line is hoisted up from the sea at high speed (Max 272m/min, 4.53m/sec). The ship is operated by delicately controlling the steering wheel while taking into consideration the ship's direction of travel, speed, and other factors. However, there is only a small distance between the edge of the ship and the longline hoist.
The worker who was operating the handle right next to the main line, which was only about 1.45m in length, was unable to operate the handle because his footing had become unstable due to the severe external force caused by the pitching, rolling, and vertical movement of the ship due to the waves. The current situation is that human effort, or in other words, human power, is not properly transmitted to the steering wheel, and people are forced to operate the steering wheel in a way that does not depend on their wishes. Particularly on the ocean during stormy weather, visibility across the seas is poor due to thick fog, and the rolling, pitching, and up-and-down movements of fishing boats make the footing extremely unstable, and the narrow spaces where sudden movements are not possible make it difficult to escape. It goes without saying that longline hoisting work, in which the mainline is hoisted out of the sea at high speed by operating a towing vehicle that rotates at high speed (Max. 324 rpm) in a work area where there is no traffic, is extremely dangerous for the worker. Not even.

However, a satisfactory safety device for this longline winding machine has not yet been developed.

``Problems that the invention seeks to solve'' Accidents caused by longline hoisting machines can be roughly divided into the following types.

The first is when a worker uses a snap fitting to clamp a tangled main rope, a branch rope attached to the main rope that is being hoisted up, or the end of a branch rope that has not been removed from the main rope. An accident in which a person was caught on a fishing hook and caught in a towing vehicle rotating at high speed (maximum 324Pm), resulting in injury.

The second is about the main rope A being hoisted up.
The branch line with a fishhook, entangled with the main line, which was under tension due to a load of 350Kgf to 400Kgf, was pulled up while spinning around the main line in a relaxed state. The moment it passes the upper side rollers, it is squeezed and jumps up, attacking the worker with ferocious force.
Accidents that result in injury, such as being struck by a snap fitting or a fishing hook, being caught, being caught in contact with a towing vehicle that is rotating at high speed (max. 324 Pm), or falling over.

Third, workers stagger, slip, fall, or become careless due to unstable footing due to pitching, rolling, and vertical movement of the ship due to waves, or other causes that cause workers to come into contact with high-speed rotating towing vehicles and become entangled. accident.

Fourthly, in order to wind up the tangled main rope as it is, the main rope may come off from the groove of the towing vehicle, or even if it does not come off from the groove of the towing vehicle, winding roller B and push roller C When the soul of the entangled main rope gets into the gap, the core of the main rope becomes misaligned with the core of the groove of winding roller B, which significantly reduces the efficiency of rope raising work, resulting in a major work loss accident.

Fifth, by winding the tangled main rope as it is, the tangled mass of main rope between the winding roller B and the push roller C becomes compressed and becomes hard, and it takes a lot of effort to untangle it. In some cases, the tangled mass may end up having to be cut out and the mainline re-tied, or as a longline fishery that requires a specified length of mainline by cutting off the tangled mass and retying the mainline. This can lead to accidents in which the main line is shortened, resulting in an unfavorable operational condition, and leads to wasted fishing materials, making it extremely uneconomical.

Anticipating these accidents in advance, workers try to operate the handle of Totsusa or suddenly stop the rotation of the longline winding machine, but as mentioned above, the footing is unstable and Totsusa's In a cramped workplace where you can't move and have nowhere to escape, it's often difficult to do what you want, resulting in constant injuries and losses due to accidents. However, such problems in hoisting work are often treated as problems of worker error or lack of skill, and the only way to solve them is to proactively deal with them and develop safety devices. had not been thought of.

Therefore, with this invention, the main line that is hoisted up in a tangled state is attached to a snap fitting that clips the branch line attached to the main line, or a fishhook that is attached to the end of the main line without removing it from the main line. etc., the machine automatically or artificially stops the rotation of the longline winding machine suddenly before the tangled mass of mainline or the fishing hook of the snap hook gets caught in the towing vehicle, or the machine automatically or artificially The longline winding machine is designed to suddenly stop the rotation of the longline winding machine when the worker slips and falls while trying to avoid flying objects, or when the worker unconsciously leans on the longline winding machine with his entire body. It is a safety device.

That is, when the safety device of the longline winding machine detects the risk of an accident, it automatically or manually cuts off the driving power of the longline winding machine with a simple operation.
The longline winding machine suddenly stops, and this not only harms the workers. The aim is to prevent danger to all workers on the side of the ship near the longline winding machine and rescue them from unexpected disasters, and at the same time, it aims to save fishing materials (main lines) and reduce work losses. It is something.

"Means for solving the problem" The safety device for longline hoisting machine according to the present invention is:
As a means to solve the above-mentioned problem, an emergency stop of the longline winding machine is provided, which comprises an operating section and a drive power cutoff section operated by the operating section, located at the front part of the longline winding machine adjacent to the mainline towing side of the towing vehicle. The equipment is installed. The operating section of the emergency stop device has an accident sensing body and a pressing body fixedly attached to a rotary shaft protruding from the mounting base so as to be rotatable, and the accident sensing body and the pressing body are connected by rotation of the rotary shaft. The driving power cutoff part of the emergency stop device is configured to rotate together with the pressing body, and the driving power cutoff part of the emergency stop device is configured to be driven by a switch pressing operation part having a restoring force and a pressing operation of the switch pressing operation part. and a switch part that cuts off the power, and is configured such that the pressing body of the operating part and the switch pressing operation part can come into contact with each other, and when the switch pressing operation part is pressed by rotation of the pressing body. The structure is such that a switch section operates to cut off the driving power source. Moreover, the accident sensing body of the operation part of the emergency stop device is disposed in the front part adjacent to the mainline towing side winding inlet of the towing vehicle, and the accident sensing body When an external force is applied and the accident sensing body rotates in the mainline towing direction, the pressing body rotates together and presses the switch pressing operation part of the drive power cutoff part to operate the switch part. This is a safety device for a longline winding machine, which is characterized in that the driving power source is cut off and the longline winding machine is stopped.

``Function'' The safety device for a longline winding machine configured as described above applies an external force in the main line towing direction to the accident sensing body of the operating section of the emergency stop device, and the accident sensing body rotates in the main line towing direction. Once this is done, the pressing bodies will rotate together and press the operation part of the drive power cutoff part to operate the switch part, thereby cutting off the drive power and stopping the rotation of the longline winding machine. It is designed to stop suddenly. The external force in the direction of pulling the main rope that is applied to the accident sensor of the operating part may be applied voluntarily by the operator or unconsciously, and may become tangled and wind up. Snap fittings that clamp the main line that is being lifted, branch lines attached to the main line, and fishing hooks attached to the end of branch lines that have not been removed from the main line may fly out and cause collisions. However, in either case, the switch part of the drive power cut-off part can be actuated quickly and reliably, thereby cutting off the drive power and suddenly stopping the rotation of the longline winding machine.

"Embodiments" The present invention will be described in detail below based on illustrated embodiments.

FIG. 1 is a front view showing an embodiment of the safety device for a longline winding machine according to the present invention, and FIG. FIG. 3 is a top view of the safety device for a longline winding machine according to the same embodiment, and FIG. 4 is a side view of the safety device for a longline winding machine according to the same embodiment, and FIG. FIG. 3 is an embodiment diagram seen from the stern showing the arrangement relationship of the .

As shown in the figure, the basic structure of the safety device for a longline hoisting machine according to the present invention is that an operating section 3 and a drive operated by the operating section 3 are installed at the front part of the towing vehicle 2 of the longline hoisting machine 1 adjacent to the main line towing side. An emergency stop device 5 for the longline winding machine 1 is provided, which comprises a power supply cutoff section 4.

The operating part 3 of the emergency stop device 5 has an accident sensing element 8 and a pressing body 9 fixedly attached to a rotating shaft 7 that is rotatably protruded from a mounting base 6, and is operated by the rotation of the rotating shaft 7. Therefore, the accident sensing body 8 and the pressing body 9 are configured to rotate together. Since the mounting base 6 is made of metal and functions as an attachment, its specific shape differs depending on the model of the longline winding machine 1 to which it is attached, and is configured in a shape corresponding to the mounting location. Rotation axis 7
is protruded from a proper position of the mounting base 6 toward the adjacent tow vehicle 2, and its rotation shaft 7 is configured to be freely rotatable. An accident sensing body 8 and a pressing body 9 are fixed to the rotation shaft 7 so as to protrude in a direction perpendicular to the axis thereof. That is, since the accident sensing body 8 and the pressing body 9 are fixed adjacent to each other on the same rotating shaft 7, when the rotating shaft 7 is rotated, both members rotate together. As shown in the figure, the accident sensor 8 is formed at the tip of the rotating shaft 7 into an arcuate plate having a diameter slightly larger (approximately 8 mm larger) than the outer peripheral diameter of the towing vehicle 2 in the longline winding machine 1. and when installed, the tow vehicle 2
It extends from the front upper part of the main rope towing side to the vicinity of the winding opening 12 at the front lower part, and is formed to protrude at a length and angle that can almost provide a protective cover. On the other hand,
The pressing body 9 is formed of a short plate on the base side of the rotating shaft 7, and is formed to protrude at an angle corresponding to a switch pressing operation part 13 of the drive power cut-off part 4, which will be described later. In addition, 10 in the figure is the accident sensor 8.
11 is a reinforcing portion provided on the back of the pressing body 9.

Next, the drive power cutoff section 4 of the emergency stop device 5 is operated by a switch pressing operation section 13 having a restoring force.
and a switch section 14 that cuts off the driving power source by pressing the switch press operation section 13.

In the illustrated embodiment, the drive power cutoff section 4 is shown as being formed in a cylindrical housing type with excellent waterproof and buffering effects in order to ensure smooth operation and durability. The drive power cutoff section 4 in the present invention can be configured as shown in the drawings as long as it has at least the switch press operation section 13 and the switch section 14 which cuts off the drive power supply by the press operation of the switch press operation section 13 as described above. Of course, there is no need to be limited to the cylinder storage method.

Here, the configuration of the drive power cutoff section 4 formed in a cylinder storage type will be described in detail with reference to the drawings. Reference numeral 15 denotes a cylindrical body 16, a waterproof lid part 17 that closes the upper part of the cylindrical body 16, and a waterproof bottom part 1 that closes the lower part of the cylindrical body 16.
8, the cylinder portion 15
The interior is divided into a buffer section 19 and a switch section 14.

The buffer section 19 includes a spindle-equipped piston section 22 that slides while fitting into a sliding guide hole 21 formed in the upper part of the cylindrical body 16 and can reciprocate in the axial direction.
and a buffer spring 23 that applies a biasing force to the spindle-equipped piston portion 22 in the direction of the waterproof lid portion 17 thereof. At this time, the spindle portion 22
a is a waterproof lid part 17 that closes the upper part of the cylindrical body 16;
When the distal end head 22b of the spindle part 22a is pressed so as to protrude to the outside through the spindle ejection hole 24, the biasing force of the buffer spring 23 is reduced. The spindle-equipped piston part 22 is pressed down against this, and the protruding tip head 22b of the spindle part 22a moves so as to sink into the cylinder part 15. Here, the function of the buffer spring 23 will be described. It has the effect of buffering the strong pressing force applied to the piston part 22 with a spindle, and the effect of biasing the piston part 22 with a spindle to a position closer to the waterproof lid part 17 during normal times. Even if it is held in the applied state and is temporarily pressed and moved by a strong pressing force greater than a predetermined value, when the pressing force disappears, the urging force restores it to the predetermined position closer to the waterproof lid part 17. has.

The buffering effect of the buffer section 19 is such that the external force applied to the accident sensor 8 during fishing work varies greatly depending on the situation, from 20 kgf to 100 tf. The load required to operate the operation part 13 is always 20 kgf ~
It is desirable that it be as small as 30kgf and constant.
This is to weaken the strong external force applied to the accident sensing body 8. This ensures that the switch body 25 is always operated with a stable and appropriate force, prevents accidental destruction of the switch body 25, and helps ensure durability.

In addition, the drive power supply cutoff section 4, which is formed in the cylinder storage system of the illustrated embodiment, is equipped with a waterproof mechanism to protect the buffer section 19, switch section 14, etc. from rainwater and waves. It has characteristics. That is, the cylinder part 15 closes a waterproof lid part 17 that closes the upper part of the cylindrical body 16, and a waterproof bottom part 18 that closes the lower part thereof, and the buffer part 19 and the switch 14 are housed in the cylinder part 15. . Such a configuration protects the buffer section 19 and the switch 14 from wind, rain, and waves outside the cylinder section 15, and protects the main rope that is hoisted up in a tangled state and the branch ropes attached to the main rope. When a worker is hit by a flying object such as a snap fitting or a fishing hook attached to the end of a branch line that has not been removed from the main line, the worker may slip and fall while trying to avoid the flying object. This is to protect the buffer part 19 and switch 14 from external forces when the body unconsciously collides with the body. 17a, 1 in the figure
7b is the spindle protrusion hole 2 of the waterproof lid part 17
It is a sealing material that waterproofs the 4 parts, 18a
is a waterproof fitting for the purpose of waterproofing the outlet portion from which the conductive wire extends from the waterproof bottom portion 18. In this way, the waterproof lid part is a cylindrical body that is sealed with the waterproof bottom part 18 and has a buffer part 19 and a switch part 14 inside.
Since it is completely enclosed and waterproofed, it will not corrode, deteriorate in performance, cause electrical leakage, or malfunction due to moisture or salt water.

Next, the switch section 14 consists of a switch main body storage section 20 formed in the lower half of the cylindrical body 16, and a switch main body 25 such as an existing limit switch stored therein. A switch operator 25a is formed protruding from the switch main body 25, and the switch operator 25a is designed so that a part thereof extends below the spindle-equipped piston part 22 of the buffer part 19 when stored. When the spindle-equipped piston section 22 is pressed and moved (downward), the switch operator 25a is pressed to operate the switch body 25 and cut off the driving power source.

That is, in the driving power supply cutoff section 4 formed in the cylinder storage system of the illustrated embodiment, the switch pressing operation section 13 of the switch section 14 is the buffer section 1.
9 and a switch operator 25a that transmits a pressing force by colliding with the switch operator 25a.

In other words, the safety device for a longline winding machine of the present invention is configured such that the pressing body 9 of the operating section 3 and the switch pressing operation section 13 of the switch section 14 are in contact with each other during normal times, and when the pressing body 9 rotates, It is constructed so that when the switch press operation section 13 is pressed, the switch section 14 is operated and the driving power source is cut off. In addition, in this embodiment, the waterproof lid part 17 is protected by the buffer spring 23 of the switch pressing operation part 13.
The biasing force in the direction supports the accident sensing body 8 and the pressing body 9 at a predetermined accident sensing position due to the contact between the pressing body 9 of the operating section 3 and the switch pressing operation section 13 of the switch section 14, When an external force is applied to the accident sensing body in the direction of towing the main rope, the accident sensing body 8 and the pressing body 9
jointly rotates in the direction of towing the main line, presses and operates the operating section 3 of the drive power cutoff section, and switches the switch section 14.
It is configured so that it can operate. However, it goes without saying that the structure for supporting the accident sensing body 8 and the pressing body 9 at a predetermined position where an accident can be detected is not limited to the system shown in the illustrated embodiment.

Moreover, the operating section 3 in the emergency stop device 5
The accident sensor 8 is disposed at the front part of the towing vehicle 2 near and adjacent to the mainline towing side winding port 12, and an external force is applied to the accident sensor 8 in the mainline towing direction to prevent an accident. When the sensing body rotates in the mainline towing direction, the pressing body 9 rotates in conjunction with the sensing body, presses the switch pressing operation unit 13 of the drive power cutoff unit 4, and operates the switch unit 14. This is a safety device for a longline winding machine, which is characterized by cutting off the driving power source.

In the safety device for a longline winding machine of the illustrated embodiment configured as described above, an external force in the direction of mainline traction is applied to the accident sensing body 8 of the operating section of the emergency stop device.
As long as the accident sensing body 8 rotates in the mainline towing direction, the pressing body 9 rotates together, presses the operation part 3 of the drive power cut-off part 4, and switches the switch part 14.
is activated, thereby cutting off the driving power and abruptly stopping the rotation of the longline winding machine. The external force applied to the accident sensing body 8 of the operation unit 3 in the direction of towing the main rope may be applied arbitrarily by the operator or may be applied unconsciously.
In addition, the main line that is hoisted up in a tangled state, the snap fittings that clamp the branch lines attached to the main line, and the fishhooks attached to the end of the main line that are not removed from the main line fly off. However, in any case, the switch section 14 of the drive power cutoff section is activated quickly and reliably, thereby cutting off the drive power and suddenly stopping the rotation of the longline winding machine. can be done.

``Effects of the invention'' The present invention consists of an emergency stop device for a longline winding machine, which consists of an operating section and a drive power cutoff section operated by the operating section, located at the front part of the towing vehicle adjacent to the main line towing side of the longline winding machine. By installing this, it is now possible to make an emergency stop of the longline winding machine in the event of an abnormality without interfering with the original longline winding work.

Next, the operating section of the emergency stop device has an accident sensing body and a pressing body fixed to a rotating shaft protruding from the mounting base so as to be rotatable, and the rotation of the rotating shaft causes an accident to occur. Since the sensing body and the pressing body are configured so that they always rotate together, there is always no disruption in the accident detection operation by the accident sensing body and the linked operation with the drive power cutoff section by the pressing body, ensuring safety. There is a high degree of certainty that it will be secured. In addition, in the unlikely event that a soul or other object gets entangled in the towing vehicle, or if you want to clean the towing vehicle, the accident sensing body and the pressing body can be rotated in opposite directions to unwind the main rope towing side of the towing vehicle. It can be kept away from the vicinity of the entrance.

Further, the drive power cutoff section of the emergency stop device is
It consists of a switch pressing operation section that has a restoring force and a switch section that cuts off the driving power supply by the pressing operation of the switch pressing operation section, and the pressing body of the emergency stop operation section and the switch pressing operation section are The switch is configured so as to come into contact with it, and when the switch pressing operation section is pressed by the rotation of the pressing body, the switch section is operated and the driving power source is cut off. Ideally, safety devices should be able to accurately judge accidents, quickly and reliably stop the accident, and prevent active malfunctions or failures of the safety devices themselves. In this way, the present invention detects an accident, makes a decision to perform an emergency stop operation, and makes a decision to start based on the decision, which is easy for humans to confirm and is carried out with high probability by stable mechanical operation. The emergency stop processing process of the longline winding machine is performed by reliable and quick electrical processing of cutting off the driving power supply, thereby improving the basic performance as a safety device as much as possible.

Furthermore, in the present invention, the accident sensing body of the operation part of the emergency stop device is disposed in the front part adjacent to the main rope towing side winding opening of the towing vehicle,
When an external force is applied to the accident sensing body in the mainline towing direction and the accident sensing body rotates in the mainline towing direction, the pressing body rotates together with the pressing body to press the switch of the drive power cutoff part. By pressing the switch to cut off the drive power, the switch is placed in the front position, and its movement follows the movement of the longline winding machine itself. The stop operation can be done in a timely manner, without any unnecessary movement, by simply pressing the accident sensor, and in addition to preventing the occurrence of tangled clumps of the main line and the removal of the main line from the grooves of the towing vehicle or winding roller. When an abnormality occurs in the hoisting operation, such as when the hoist comes loose, an emergency stop operation is activated not only manually but also automatically, in an attempt to improve its performance as a safety device. Therefore, if the safety device for a longline winding machine according to the present invention is installed, it will be possible to prevent accidents for workers.
Not only is it a safety measure, but it also prevents tangled chunks of the main rope from being caught between the winding rollers and pushing rollers, and prevents the tangled chunks from becoming compressed and solidified, making it easy to remove tangled chunks and This can contribute to saving fishing materials and shortening the time required for winding up fish, such as by freeing people from the troublesome work of untangling them.
