Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a net hoisting machine for hoisting a fish net that is being delivered to the ocean onto a ship.

[0002]

[Prior art]

 Conventionally, a fish boat or the like is loaded with a fish net of a length of several hundred meters or more, depending on the size of the boat, and the fish net is set in the ocean. Then, a net hoist is installed on the deck to lift the fish net. The scissors installed on the net hoist rotate on a vertical plane, and the net hoist is rotatably moved in the left-right direction so that the scissors are oriented in the direction to pull up the fishnet.

As an example of the fish nets handled here, as shown in FIG. 12, an upper rope (upper shelf) having a float 2 on a rope 1 and a lower rope (lower shelf) without any attachment are parallel to each other. There is a structure in which a net cloth (mesh thread) 3 is tied between them and is connected. The machine used to lift the fish net 4 from the ocean is a net having a structure in which a driving means (motor) 7 is attached to a scissor wheel 6 having an annular groove 5 formed in the circumferential direction as shown in FIGS. 10 and 11. The hoisting machine 8 is installed on the deck and operated. The groove 5 of the scissor wheel 6 is formed in a substantially V shape, and a fish net repelling plate (repelling plate) 9 having a shape following the cross-sectional shape of the groove 5 is wound around the fish net 4 with its tip facing the groove bottom. It is installed at the bottom of the scissors 6 on the side to be taken.

When pulling up the fishnet 4, the rope 1 is put into the groove 5 and the scissor wheel 6 is rotated. The rope 1 bites into the pair of inclined wall surfaces 5a of the groove 5 by a pulling force or the like, and is carried by the rotation of the scissor wheel 6. When the rope 1 reaches the rotating position of the scissor wheel 6 where pulling force is not applied, the rope 1 is forcibly removed from the scissor wheel 6 by the fishnet repelling plate 9. As a result, the fish net 4 is not wound around the scissor wheel 6 but is stacked on the deck by the operator.

[0005]

[Problems to be solved by the device]

 However, although it is good to wind the rope with the scissors 6 to hold the fishing boat, for example, when the fish net 4 is wound, the net thread 3 is attached, so it is necessary to sort it out. The fishnet baffle plate 9 collides with the fishnet 4 (rope 1 and net thread 3), and wear and warpage occur depending on the frequency of use, etc. The tip of the fishnet baffle plate 9 and the shaft part of the scissor wheel 6 A gap 10 is formed between the and. Since the net cloth (net thread) 3 may be caught in the gap 10 and the net cloth (net thread) 3 may be caught at the tip of the fishnet repelling plate 9, the worker may not set the net cloth (net thread) 3 The accident was prevented by moving the to prevent it from entering the gap 10. Further, due to this workability, the rotation of the pinion wheel 6 is slowed down, and the work is complicated.

An object of the present invention is to provide a net hoisting machine in which net cloth (net thread) is not caught or caught when the fish net is wound.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention rotatably drives a scissor wheel having an annular groove formed in a V-shaped cross section in the circumferential direction on a vertical plane to partially form a fishnet in the groove. In a net hoist for pinching and pulling a rope, the annular groove bottom of the scissors is covered, and a ring portion having a width narrower than the outer diameter of the rope is formed at the tip of a column that stands upright on the base. A groove is formed from the surface of the ring portion and a vertical wall surface that is in sliding contact with both ends of the ring portion and an inclined wall surface that expands outward from the outer peripheral edge portion of the vertical wall surface, and the diameter of the outer peripheral surface of the ring portion is set to the vertical wall surface. The diameter of the outer peripheral edge of the ring is equal to or smaller than the diameter of the outer peripheral edge of the ring part, and a repulsion plate in a shape that closely follows the vertical wall surface and the inclined wall surface is smoothly integrated with the surface of the ring part on the lower surface of the ring part and the side surface of the column. It is characterized by being installed in.

[0008] Furthermore, a scissor wheel having an annular groove formed in a substantially V-shaped cross section in the circumferential direction is rotationally driven on a vertical surface, and a rope which forms a part of the fishnet is sandwiched in the groove and pulled up. In the upper machine, a ring portion narrower than the outer diameter of the rope is formed at the tip of a pillar standing upright on the base, covering the bottom of the annular groove of the scissors, and the surface of the ring portion and the ring portion A groove is formed by a vertical wall surface that slidably contacts both ends and an inclined wall surface that expands outward from the outer peripheral edge portion of the vertical wall surface, and the diameter of the outer peripheral surface of the ring portion is equal to the diameter of the outer peripheral edge of the vertical wall surface. Alternatively, a recess or eave is formed in the lower part of the surface of the ring part, and a repelling plate having a shape that closely follows the vertical wall surface and the inclined wall surface is provided, and the tip of the repelling plate is located in the lower part of the recess or eave. The feature is that it is inserted and fixed to the pillar.

[0009]

[Action]

 The net hoisting machine according to the present invention pulls the fish net into the groove of the scissor wheel when the fish net is pulled up from the ocean, and the fish net is pulled up by rotating the scissor wheel, and the deck is moved away from the scissor wheel by the repelling plate. It is piled up in a ring on top. Since the baffle plate is integrally provided on the ring and the column arranged on the outer periphery of the center of the groove of the scissor wheel, the surface from the ring to the baffle plate is continuous without break and is tied to the rope. The nets (net yarns) of the fish nets are smoothly pulled up along the limbus and the repelling board.

Further, when the support column and the repelling plate are separated from each other, the tip of the repelling plate penetrates into the ring portion and is hidden. Does not stick out.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, a net hoisting machine 8 has a base 12 erected on a floor surface (deck) 11 on which a drive means 7 using a motor or an engine for rotating a scissor wheel 6 or an engine is fixed. 7 is connected to the scissor wheel 6 by means of a coupler 13. The driving means 7 uses a motor or an engine, and the coupler 13 is provided with a speed reducing means. Further, the base 12 is provided so as to be rotatable left and right.

The scissor wheel 6 has an annular groove 5 formed in the circumferential direction, and the cross section shape of the scissor wheel 6 is a disk 14 having a thickness smaller than the outer diameter length of the rope 1 which partially constitutes the fishnet 4. Outer peripheral surface, a vertical wall surface 15 extending diametrically from both ends of the disk 14, and an inclined wall surface 5a that expands outward from the outer peripheral edge of the vertical wall surface 15 (see FIG. 3). ).

The disc 14 of the scissor wheel 6 is covered by a ring portion 17 formed on the upper portion of the pillar 16 shown in FIGS. It is fixed to. The thickness of the ring portion 17 is slightly smaller than the thickness of the disk 14, and the diameter of the outer peripheral surface of the ring portion 17 is equal to or smaller than the diameter of the outer peripheral edge of the vertical wall surface 15. In addition, the repelling plate 19 shaped so as to be close to the vertical wall surface 15 and the inclined wall surface 5a is pulled up by the scissor wheel 6 of the wheel portion 17 and the lower portion of the side (see FIG. 5) on which the rope 1 falls (see FIG. 5). The surface is continuously and integrally manufactured at a position where the rope tension is not affected.

As shown in FIG. 5, when the fishnet 4 is pulled up by the net hoisting machine 8, the rope 1 is inserted into the groove 5 formed on the outer periphery of the scissors 6. Next, when the scissor wheel 6 is rotated, the rope 1 is pinched by the tension, and the rope 1 is pulled up as the scissor wheel 6 rotates. When the rope 1 (fish net 4) that has been pulled up collides with the repulsion plate 19 whose surface is continuously integrated with the ring portion 17, the rope 1 is disengaged from the scissor wheel 6, and the mesh thread 3 interferes with the ring portion 17 that is in sliding contact. I will be separated. This allows the worker to wind the fishnet 4 on the deck.

Further, as shown in FIGS. 6 and 7, the repelling plate 19 may be separated from the support 16 via the bracket 20, and the tip of the repelling plate 19 may be fitted into the recess 21 formed in the ring portion 17. And fix it securely. As a result, the rope 1 separated from the scissor wheel 6 easily hangs at a position slightly separated from the net winding machine 8 and the winding operation becomes easy. Further, even if the repelling plate 19 is bent, the tip of the repelling plate 19 does not project, so that the entanglement of the mesh yarn 3 can be prevented. Further, when the repelling plate 19 is consumed due to the collision with the fishnet 4, the repelling plate 19 is detached from the bracket 20 and the outer shape is shaped and then reassembled, or a new repelling plate 19 is replaced.

Further, as shown in FIG. 8, by mounting the repelling plate 19 obliquely, the rope 1 can be guided downward and the winding operation becomes easy. In this case as well, the tip of the repelling plate 19 is fitted into the recess 21 formed in the ring portion 17. If the recess 21 cannot be formed, the eaves 22 is formed as shown in FIG. 9, and the tip of the repelling plate 19 is brought into contact with the eaves 22 to prevent the mesh yarn 3 from being caught. it can.
