Description

A manufacturing method of a crab pot and its method for constructing a fishing net}

The present invention mainly relates to a method for producing a fish kkeol skeleton for catching crustaceans, the configuration of kkeulk skeleton, and kkeul using the same.

Usually, fish traps for the crustacean catch are operated year-round in the seabed and the bottom of the water at a depth of 100m to 1000m, and they are caught as bait such as mackerel or sardine in the trap having one inlet of acrylic or plastic on the top of the trap. Attract and capture the object. In general, about 240 boats per boat are used for a total of 1,200 to 1,500 buckets in several places. Then win the next one. The pitcher will work at high speed along the lumber line, especially undersea valley, while the winch will wind up the hairline to the hydraulic lifter at the port through the guide roller on the starboard side. The lifted traps are transported to the stern by handling catches, refitting bait, and repairing the damaged parts of the traps. The bristle line is sent to the stern through the pipeline to prepare for the next ride. It takes about 1 hour to ride a tank and about 6 to 7 hours to get on and off.

Conventionally known traps used in these operations are formed by simply welding the annular frame connections to the up and down sides. And the annular frame is connected to each other by a plurality of support rods are connected to each other and fixed, and the outside of the completed frame is relatively meshed with a wide mesh to form a complete trap. In the above, the mesh and the annular frame are usually bound by winding the annular frame using a long rope. Such a binding method has a variety of problems even when repairing the fishing nets due to poor workability due to binding by using a long rope, and also when repairing fishing nets. When the mesh is caught in protrusions, etc., it causes the trapping frame and the mesh breakage.

In addition, in the conventional trapping structure, the welded portion of the circular frame is directly exposed to the outside, and the corrosion is easy, and the load and the external force due to seawater resistance are concentrated, so that the trap breaking and the damage are frequent, so that the catches are largely lost. In addition, it is also a problem to environmental pollution, such as the case that the damage caused by damage and damage during operation is difficult to repair.

Moreover, in order to improve catching per unit, the large amount of traps should be loaded in a limited space during the export. In the conventional trap skeleton, the bottom bending portion of the holding rod protrudes inward and mutually interferes with each other. Dead Space) is generated, and a lot of space is generated. In addition, the load of the traps loaded on the upper part is added to the holding rods of the traps loaded on the lower part of the loading layer, which is another cause for deformation and damage of the traps, and it is pointed out as a problem for safety because it does not form a stable loading shape when moving. Has been.

Therefore, the present invention is to provide a method for manufacturing a trap and a trap skeleton using the configuration and the trap using the same configuration that can solve the above problems.

The first technical problem to be achieved by the present invention is to achieve a new manufacturing process suitable for mass production system by developing a variety of jig, device or devises necessary for improving the productivity and cost reduction when producing a shell for catching shellfish. In other words, many processes have been advanced by hand making in the traps produced by the conventional fine manufacturing process. That is, the conventional method of manufacturing the trap can not only produce a lot of time or human loss, but also it is difficult to accurately produce the trap skeleton in a circular shape, and the holding rods of the trap skeleton are symmetrically coupled with the circular skeleton. As a result, the finished trap has been a problem for its durability as a mechanical structure. To this end, the present invention solved such problems by developing a jig for assembly and welding, a circular frame bending device, and the like, for the production of a concentricity and a symmetrical trap.

Secondly, the conventional trapped frame has been a problem due to the frequent occurrence of damage to the joint portion of the circular frame joint and the connection between the circular frame and the holding rod by the load and external force due to seawater resistance during the lifting operation.

Accordingly, the present invention is intended to produce a trap frame having a structure excellent in durability even in the concentrated load added to the trap. In addition to forming a circular frame with excellent concentricity by a novel method, we devised a circular frame with a joint protection function to protect welded joints of the circular frame, and also invented an original method to produce a trapped frame with excellent symmetry. The designed assembly welding fixture is designed. This jig has greatly increased work efficiency and cohesion between circular frame and prop rod by facilitating Symmetrized Binding and Welding Process of supporting rod and circular frame.

Thirdly, in order to increase the catch, it is necessary to load a large amount of traps in a limited space at the time of departure, the present invention to maximize the loading capacity of the traps per unit space, to produce a trap in a frame structure that is easy to access crustacean on the net It is in a ship.

Conventional trapping structure is formed by bending the shape of the lower end of the support bent inward from the inside due to ease of assembly and welding during the manufacturing process. Such conventional trap shape is formed in the dead space in the upper direction of the loading due to the generation of waste space caused by the interference of the bent portion when loading the trap, not only to form an unstable structure when moving, but also added to the large concentrated load on the support rod of the trap loaded on the lower layer It is a cause of deformation and damage to the trap structure. The present invention solves the above problems by devising a jig for assembly welding, the lower end of the support rod bent in a manner suitable for mass production system. In addition, when the mesh is formed in the trap structure formed in the main body, the accessibility of the crustacean is increased by gently and smoothly forming the slope of the lower inlet portion, which is a problem of the lower net forming portion formed by the conventional trap structure.

Fourthly, due to the nature of the crustacean fishing, when the catch is collected, the net is damaged frequently and damaged nets or traps should be made quickly between the climbing and the transfer operation. The net binding method formed by the conventional net binding method formed on the traps uses a long rope. When the specific part of the rope is damaged, not only the entire net is lost, but there is a problem that the binding and repair with the net is not easy.

In order to prevent the loss of catches due to breakage of the net during fishing of the trap, it is possible to quickly and easily repair the net damage or damage in the fishing operation by the multi-net method by the detachable band-type net binding member. In other words, when binding the net to the skeleton frame, it is possible to form a double or multiple nets according to fish species, fisheries and the estimated fishing amount, and devised a detachable net binding member suitable for the rapid maintenance of the net during fishing. Such a net binding member can greatly reduce the possibility of catch loss due to the breakage of the net, and can effectively bind and repair the net.

To provide fish catches.

First, in order to produce a circular frame conforming to the gist of the present invention, it is necessary to develop an annular frame manufacturing apparatus and the production of an annular frame having a weld protection.

The manufacturing of concentric annular frame is a very important factor in producing a durable trap by distributing the load or external force acting on the trap, and also the loading rate of the completed trap and the capacity of the trap. It is also an important component requirement for the formation of a robust mesh.

Figure 1 is a plan view showing the annular frame bending device constituting the present invention, Figure 2 is an enlarged cross-sectional view showing the main portion for showing the operation of Figure 1, below the operation of forming an annular frame according to the present invention It will be described in detail below.

The annular frame manufacturing apparatus 100 is provided with a disk-shaped rotating disc 130 having a large rotational inertia moment (rotational inertia Moment) is installed in the motor 120 is provided on the bottom of the table 110. The rotating disc 130 is provided with an insertion unit 131. The guide pin 140 is coupled to the table 100 in three outer circumferential directions of the rotary disc 130. The guide roller 150 is located on the same arc as the guide pin 140, and the pressure roller 161 operated by the hydraulic cylinder 160 is located at the rear thereof. In addition, there is another guide roller 151 in front of the guide roller 150 by holding the guide rods to cross. A guide pin 141 is provided between the side guide rollers 150 and 151 to prevent the round bar from escaping upward.

The manufacturing process of the annular frame manufacturing apparatus 100 having the above configuration is as follows. That is, one end of the round bar cut to the length corresponding to the outer diameter of the rotary disk 130 is mounted to the insertion portion 131. On the outside of the insertion portion 131 on which the round bar is mounted, a compression roller 161 operated by the hydraulic cylinder 160 is positioned. The inserted round bar is in close contact with the rotating disc 130 by the pressing roller 161. Next, by rotating the rotating disk 130 by 360 degrees to form a circular annular frame 170 of excellent roundness on the outer circumference of the rotating disk 130. After the annular frame 170 is formed by the rotation of the rotating plate 130 as described above, the hydraulic pressure applied to the pressing roller 161 is released to drop the annular frame 170 which is in close contact with the rotating disc 130 to the lower side of the rotating disc 130.

Figure 3 is a perspective view showing another embodiment of the annular frame manufacturing apparatus of the present invention and Figure 4 is an exploded perspective view of Figure 3 as a basic configuration as described above.

Rotational disk 132 in the above is the two ring bodies 133,134 are fitted on the outer periphery to facilitate the disassembly and coupling on the outer circumference is fixed on the inner rotation disk 132 by the connecting rod 135 and the fastening means 136 and according to the size of the annular frame 170 The ring body 134 or the second ring body 133 may be separated and used. At this time, the rotating disks 132 and the first and second ring bodies 134 and 133 are provided with insertion portions 132a, 133a and 134a, respectively, and the grooves are formed in the first and second ring bodies so as not to interfere with the inserting portion located inside. In addition, in order to move the position of the guide pin 140 on the table 110 is formed a guide groove 111 which is a long groove toward the center and the guide pin 140 is coupled to be moved. And the guide grooves 112 are formed in the horizontal direction on the table 110 to enable the movement of the guide pins 141 to prevent the guide rollers 150, 151 and the bar from being separated upward.

By using the annular frame manufacturing apparatus 100, 100 'having the above-described configuration, it is possible to form an annular frame and to form an annular frame having excellent roundness of various sizes through a simple operation.

When the round bar is formed in the annular frame 170 by the above method, the connecting part should be connected by connecting means such as welding. In the present invention to provide a protective cover that can protect the connecting means to protect the connecting means, will be described in more detail based on the accompanying drawings.

5 is a cross-sectional view showing various embodiments of attaching a protective cover 180 to protect the connecting means 173, such as welding, in the connection of the annular frame formed by the apparatus of FIG.

That is, in order to protect the connection means 173 as described above, in order to position the protection cover 180 outside the connection means 173, a protective cover 180 having a pipe shape is inserted into the frame before welding both ends 171 and 172 of the annular frame 170. Then, both ends 171, 172 of the annular frame 170 are welded in a conventional manner to form a completed annular frame 170.

Next, the protective cover 180 is placed on the outside of the welded connecting means 173 and fixed to the framework by various fixing methods to protect the connecting means 173.

The fixing method is to place the protective cover 180 on the outside of the connecting means 173, as shown in the connecting means 173 to form a coupling hole 181 penetrating through the protective cover 180 and the annular frame 170 to the rivet 182 inserted therein (Riveting) or inserting both ends 183a and 183b of the connector 183 having a roughly '' shape into the coupling hole 181 and pressing the ends 183a and 183b of the connector 183 protruding to the opposite side with a press, or both sides of the protective cover 180. The annular frame 170 is welded or fixed to the annular frame 170 to the protective cover 180.

As described above, when the protective cover 180 is positioned outside the connecting means 173, the life of the trap can be extended by minimizing the failure rate due to corrosion, stress or load concentration at the connecting means 173, that is, the connection means 173. Since the effect of being connected again by the protective cover 180 located on the outside can be obtained again, the binding force is further improved to prevent breakage or loss of traps due to breakage of the connection means 173. In addition, the annular frame 170 completed in the above configuration is to form an accurate circular shape, it becomes an annular skeleton 170 of the outbreak having enough durability to withstand internal load or external force.

Figure 6 is a perspective view showing the bending jig of the holding rod used in the present invention, Figure 7 shows a cross-sectional view showing the holding rod bending state of FIG.

According to the present invention, the bending fixture 200 of the holding rod is placed on the pressing plate 230 which is raised and lowered by an external force (cylinder or pressing device, etc.) on top of two support rods 220 and 221 fixed to the base 210 at a predetermined interval as shown. During operation, the pressing plate 230 is inserted between the two supporting rods 220 and 221 to bend the end of the main rod 240 to be inserted in the direction perpendicular to the rods 220 and 221. The second supporting rods 220'221 'and the pressing plate 230' may be formed on the side so as to form a plurality of holding rods 240 at the same time. A work table 250 is formed in front of the base 210, and a hole 251 of a predetermined size is formed therein so that one side ring part 241 may be inserted when the holding rod 240 is bent.

When manufacturing the holding rod 240, the ring portions 241,242 formed at both ends should be bent symmetrically with respect to the rod body.

Second, by providing a jig 300 that can combine the holding rod and the annular frame to reduce the failure rate more effective.

In the construction of the trap, the coupling structure of the annular frame 170 and the holding rod 240 and the method is an important matter to determine the shape of the fishing trap frame. Structural mechanics is essential to form the same cabinet between the holding rods 240 coupled to the upper and lower annular frame 170, 170a, 170b to ensure that the correct symmetrical shape when the coupling. As such, the support rods 240 are essentially required as shown in order to become an accurate symmetrical shape on the annular frame 170, 170a, 170b.

Figure 8 is a perspective view showing a jig for assembly and welding the trapezoidal frame of the present invention, Figure 9 is a front view of Figure 8 as a process diagram showing the coupled state of the jigsaw structure of the present invention.

The knives skeleton frame 300 of the present invention is the first, second, and third sizes of the three-stage type on the rotatable shaft 310 in the center to seat the annular skeletons 170, 170a, 170b located approximately in the upper and lower sides and the middle of the barrel Attach the 3 rotating plate 320, 330, 340. At the edges of the second and third rotating plates 330 and 340, a plurality of fasteners 331 and 341 capable of fixing the annular frameworks 170a and 170b are formed to protrude. And one side of the fasteners 331,341 is formed with a space portion 332,342 of a predetermined size to install the holding rod 240. In addition, a space portion 322 is formed on the first rotating plate 320 as in the second and third rotating plates 330 and 340. A support device 350 having elasticity is provided between the second rotary plate 330 and the third rotary plate 340 of the jig 300 of the present invention to support the holding rod 240 positioned at a predetermined angle through each of the spaces 322, 332 and 342. At this time, the support device 350 is welded and fixed in a state inclined about 40 degrees on the second rotating plate 330.

As shown in FIG. 10, the supporting device 350 has a structure in which the second support 352 is fitted to the first support 351, and there is provided a support means 353, which is a coil spring, between the first and second support 351, 352. At the end of the large 352, an indentation groove 354 capable of incorporating the holding rod 240 is provided.

In order to complete the trapped skeleton 1 using the jig 300 of the present invention having the above configuration, it must go through the following steps.

1) The upper annular frame 170b is inserted into the fixture 341 of the third rotating plate 340 to be seated.

2) Then, the intermediate annular frame 170a is fitted to the fixing tool 331 of the second rotating plate 330 to be seated.

3) Next, the upper annular frame 170b is hooked so that the ends of one side ring portion 241 of the support rod 240 symmetrically bent by using the space portion 342 so as to face inward, and the rod of the support rod 240 is supported by the support device 350. 2 Mount the support rod 240 to each support device 350 by mounting it to the indentation groove 354 in the support 352.

4) While inserting the lower annular frame 170 into the opposite ring portion 242 of the holding rod 240 mounted in the above-described manner, the annular frame 170 is inserted into the fixture 321 of the first rotating plate 320.

5) Next, the ends of the holding rods 240 located at the upper and lower annular frames 170b and 170 are pressed tightly to the annular frames 170 and 170b by pressing the ends thereof by a gripping device (not shown).

6) Next, after fixing each of the annular skeletons 170, 170a, 170b and the holding rods 240 in contact with each other located in the upper and lower sides, and then separate the finished trap skeleton 1 in the jig 300.

Using the assembly and welding jig 300 configured as described above to assemble and weld the annular frame 170, 170a, 170b and the holding rod 240 in the process order to complete the trap skeleton 1 more quickly to the annular frame 170, 170a While coupling the holding rods 240 on the 170b, the symmetry is excellent, and the coupling structure is provided with a finished trapped skeleton 1 having a dynamically stabilized structure.

Figure 11 is a perspective view of the trapped skeleton completed by the above-described jig of the present invention, Figure 12 shows a simplified front view of the net covering the trapped skeleton of Figure 11, the ring portion 242 coupled to the lower annular skeleton 170 When the net 400 is bound by the binding line by being protruded to the outside, the lower end of the mesh 400 forms a curved portion 2 smoothly into the trap skeleton 1. During fishing, the shaking of the mesh 400 is greatly reduced by the influence of the algae, and the lower end of the mesh 400 is smoothly formed. In addition, since the lower end of the mesh 400 keeps the curved portion 2 smoothly into the inside of the trap, it naturally escapes from obstacles such as the protruding rock, thereby preventing the break of the trap. This smooth curve 2 facilitates access to the crust of the crustaceans.

Tonggol frame 1 is completed in this state is the annular frame 170, 170a, 170b is maintained in the roundness, the holding rods 240 is completed in a symmetrical structure is completed in this case when the trapped in the seawater, the load by the catch and resistance to seawater The load is distributed by the holding rods 240 of the symmetrical structure, thereby preventing the damage and damage of the trap, thereby extending the life of the trap. In addition, the structure of the trap skeleton 1 completed by the jig 300 of the present invention can significantly increase the loading ratio of the trap to the unit space.

That is, in the conventional trapped skeleton 10, the bent portion of the collar 15 is inwardly hung on the upper and lower annular frames 11, 13 by holding the support rod 14, which provides the collar 15, which is formed at both ends on the outer side of the upper and lower annular frames 11, 12, 13 It was used in combination. This conventional trapping structure is to produce the trap skeleton 10, or to cover the net to the finished trap skeleton to complete the trap and load the trap to the state of loading or moving, storage of the trap when shown in Figure 13 It becomes the state.

Thus, the completed trap is loaded by the bent shape of the lower ring portion 15 of the holding rod 14, it can be seen that a space is created between the trap and the trap due to the bending shape interference.

However, the trap is completed in the present invention, as described in detail above, both sides of the holding rods 240, cyclic symmetrical configuration of the two sides of the holding rods 240, using the upper annular frame 170b hook the ring portion 241 from the outside to the lower annular skeleton 170 On the contrary, it is configured to hang the hook 242 from the inside to the outside, the loading state of the finished trap according to the present invention is lost dead space (Dead Space) when loading the trap. Furthermore, the present invention is to support the holding rod 240 coupled to the annular frame 170, 170a, 170b in the manufacturing process is to provide a factor that further improves the loading effect of the present invention as it has an excellent symmetry structure as shown in Figure 14 do.

Comparing the loading state of the above-mentioned conventional completion canister and the finished cantilever according to the present invention can be confirmed the following differences.

The conventional finished canister loads 315 pieces when loaded into a container of about 40 feet. On the contrary, the finished trap according to the present invention may load at least 586 or more traps under the above conditions. Such trapped skeleton of the present invention can be seen that the loading rate is improved by about 186% or more compared to the conventional skeleton. This can reduce the production cost of traps due to the reduction of logistics costs, and can also greatly contribute to the increase in catches, since a large amount of traps can be loaded in a limited space during fishing operations.

Third, when binding the fishing net using a common net to the finished frame, a detachable band-type binding member was used in order to facilitate the fishing net binding work easily. It will be described in more detail below to be placed or, by overlapping the net at the lower end to prevent the loss of captured catches due to the breakage of the net.

Figure 15 is a perspective view showing a state in which the net is trapped in the trap skeleton completed in the present invention, in a conventional fishing trap, the net mesh 400, the annular frame 170, 170a, 170b and the holding rods 240 outside 170, 170a, 170b and the holding rod 240 is bound to the binding member 500 to allow the mesh 400 to be more securely protected by the lower annular frame 170 in the aerosol.

Figure 16 shows a second embodiment of the method of binding the net, in the conventional fishing vessels, to place the mesh 400 in the annular frame 170, 170a, 170b and the holding rod 240 and the mesh 400 and the annular skeleton 170, 170a , 170b and the holding rod 240 is bound to the binding member 500 so that the net 400 can be more securely protected by the lower annular frame 170 in the aero.

In addition, Figure 17 shows a third embodiment of the method of binding the net, to place another mesh 410 inside the annular frame 170, 170a, 170b to correspond to the mesh 400 covered on the outer frame 170, 170a, 170b inner mesh 410 is located only between the lower annular frame 170 and the intermediate annular frame 170a and binds the mesh 400, 410 to the annular frame 170, 170a, 170b and the holding rod 240 as the binding member 500, even if the outer mesh 400 is severely damaged, the inner mesh 410 To protect the catch.

In order to bind the mesh as described above, the following binding member is required.

18 is a perspective view showing a binding member for binding the net in the present invention and Figure 19 is a cross-sectional view showing the binding state of FIG.

The binding member 500 of the present invention provides binding holes 520 and 530 that are insert inserts (Plastic Insert) on both sides of the rope 510. At this time, the engaging groove 521 is formed in one side binding hole 520, and the engaging protrusion 531 to be inserted into the engaging groove 521 is formed in the other side binding port 530 so that the band-type binding member 500 is completed by mutual combination. When the binding member 500 is used, the binding member 500 is interposed between the meshes 400 positioned on the frame, and the binding members 520 and 530 are fitted to each other to bind the trapped skeleton and the mesh. At this time, the person who binds the mesh 400 should ensure that the binding ports 520,530 of the binding member 500 are not exposed to the outside of the trap and are located inside the trap.

That is, in the present invention, the mesh 400 coupling is a binding member 500 in a state where the mesh 400 is positioned inside the support rod 240 and the annular frame 170, 170a, 170b of the fishing barrel skeleton 1 configured in the shape of a circular (Circular Teeth Type). By binding and fixing, since the mesh 400 is located inside the lower annular frame 170 during fishing, the annular frame 170 prevents the mesh 400 from coming into direct contact with the bottom of the sea to reduce the possibility of breakage of the mesh 400 and lift the catch safely. Can be. In addition, the present invention by using the inner bottom of the double mesh 410, even when the outer mesh 400 can be securely lifted the capture by preventing the capture attracted to the inside of the trap by the inner mesh 410 to escape to the outside.

As described above, the present invention provides a mechanism for forming an annular frame and a holding rod, a jig frame for assembling and welding the formation, and a mesh frame to the trapped frame completed from the device and the device, and using the binding mechanism to form a frame. This invention relates to a fish trap for manufacturing a trap by binding a net to the net, and as described above, by placing a protective cover on the connection means of the annular frame, the damage rate due to corrosion, stress, or load concentration at the connection means, ie, welded portion, can be obtained. There is an advantage in extending the trap life to a minimum.
