Description

The present invention relates to a shell removing device used for removing scallops, oysters, shellfish, oysters, etc. (collectively referred to as “shells”) that are cultivated by suspending and suspending the rope together in the sea. and is related to shellfish removal method, it of course be able to remove the shellfish while raising can pull the shellfish with a rope from the sea, or remove the ship raised can pull the ship, also be or used in land It can be done.

  Shellfish are sometimes suspended (referred to as “ear-hanging culture” in scallop farming). The ear-hanging aquaculture is a plastic shell locker K (Fig. 1) or tegus inserted into a rope, passed through a hole in the shell and attached to the rope, and the rope with the shell suspended in the sea It is a method to do.

In the conventional ear-hanging aquaculture, as shown in FIG. 9A, a shell-attached rope 3 in which a shell 1 is locked to a rope 2 is hung on the outer periphery of a pulling rotator B installed on a ship A. ,-out downstream pull from sea is pulled onto the ship a in retraction device 6 provided (in the case shown in FIG. 9 (a) is composed of a retractable rotary member 4 and pusher 7) (right side in the figure) At this time, the shellfish 1 is removed from the rope 3 with shellfish by the shell removal tool 5 disposed between the pulling rotator B and the pulling rotator 4. The pulling rotator B and the pulling rotator 4 are rotated by a driving device such as a motor.

  The shell removing tool 5 has a ring shape partially opened, and the inner passage 5a has an inner diameter through which the rope 2 can pass but the shell 1 cannot pass through. Therefore, when the rope 2 of the rope 3 with shellfish is drawn into the passage 5 a, the shellfish 1 is caught by the shell removal tool 5 and detached from the rope 2. In some cases, the shell 1 is detached from the rope 2 together with a shell stopper K for locking the shell 1 to the rope.

  The shell removing tool 5 may be a U-shaped shell shown in FIG. The U-shaped shell removing tool 5 also has a passage 5a. The width of the passage 5a is wide enough to allow the rope 2 to pass through, but not wide enough for the shellfish 1 to pass. The shellfish 1 is caught by the shell remover 5 and is detached from the rope 3 with shellfish.

  As shown in FIG. 9 (a), the rope 2 from which the shells 1 have been removed is drawn downstream (the deck of the ship A) by the drawing rotary body 4. At this time, the rope 2 is smoothly guided downstream, and the rope 2 is prevented from being pulled back by resistance when the shellfish 1 is caught by the shell removal device 5. And the rope 2 drawn by the drawing rotator 4 is pressed against the drawing rotator 4 by the pusher 7 and the rope 2 is drawn downstream by the rotation of the drawing rotator 4 and the rotation of the pusher 7. It is. In the example of FIG. 9A, the retraction rotator 4 rotates clockwise, and the pusher 7 rotates counterclockwise. As shown in FIG. 9 (b), the drawing rotor 4 has two disks 4a and 4b oppositely connected by a connecting shaft 8, and the rope 2 is pressed against the drawing passage 4c between the disks 4a and 4b by a pusher 7. It is drawn while being pulled. The pusher 7 is pulled toward the retracting passage 4c by a spring (not shown) and pressed against the retracting passage 4c so as not to slip the rope 2. There may be no pusher 7.

  Under the pusher 7, a rope flip 9 is provided. The rope flip 9 prevents the rope 2 from getting caught so that the rope 2 drawn between the drawing rotor 4 and the pusher 7 is not pushed into the drawing passage 4c more than necessary (does not wind). The distal end portion 9 a has a sharp wedge shape, and the distal end portion 9 a is disposed in the retracting passage 4 c of the retracting rotary body 4.

  The shells 1 that have been caught by the shell removing tool 5 and detached from the rope 3 with shells are received by the receiving tool C inclined downward on the inside of the ship, and are slid on the receiving tool C and stored in the storage basket D in the ship. . The stored shellfish 1 is then washed, cleaned on the surface if necessary, and sorted according to size before shipment.

  As described above, the drum-shaped pulling rotary body B has been used for the shell removing device used when landing the shell 1 in the conventional suspended culture. As described in Patent Document 1, this pulling rotary body has been widely used.

Japanese Patent Laid-Open No. 10-136833

Conventionally, a slide E shown in FIG. 10 may be used in place of the drum-like pulling rotary body B. The slide E shown in FIG. 10 makes the surface F smooth so that the rope 3 with shellfish can pass smoothly, and prevents the rope 3 with shellfish from dropping (sliding down) from the surface F on both sides in the width direction of the surface F. Side walls G (FIG. 11) are provided. The surface F of the slide E is curved in a side view curve shape so that the rope 3 with shells can smoothly transition from a vertical posture in which it is suspended in the sea to a horizontal posture in the ship. Shellfish rope with the curved shape and smooth surface of the surface F 3 are are smoothly so raised Pull on board.

  FIG. 10 shows an example in which the retraction rotator 4 and the pusher 7 are installed so as to rotate on a horizontal plane. Although this installation posture is different from that in FIG. 9A, the operation is the same as that in FIG. 9A. In FIG. 9A, the retractable rotating body 4 and the pusher 7 may be installed in a horizontal posture. Alternatively, the retractable rotary body 4 and the pusher 7 of FIG. 10 may be installed in a vertical posture (FIG. 11).

In the case of a shell hanging rope 2 (usually about 6 to 8 mm in diameter) that is suspended in the sea with the shell 1 locked, for example, in the latter half of the year, depending on the length and the number of shells 1 to be attached. On the other hand, a large amount of Zaraboya or the like adheres to the shellfish 1 or the rope 3 with shellfish, resulting in an apparent diameter of 100 to 200 mm and a weight of 30 to 50 kg per bottle. Thus heavy since bring can pull the shellfish with rope 3, Toka shellfish rope with 3 not be raised-out smoothly pull slips in the body outer circumferential surface of the pulling rotator B (FIG. 9 (a)), shellfish There was a problem that 1 fell off the rope 2 by rubbing with the pulling rotary member B. 10, for slide E in FIG. 11 has no force bring can pull the shellfish with rope 3, will be cited can pull the shellfish with rope 3 only retractable rotary body 4, smoothly hardly raised can pull the shellfish with rope 3 There was a problem.

Object of the present invention, aquaculture and natural products, in particular, long or seafood as kelp, etc., the shellfish with rope miscellaneous matter is adhered in large quantities when bring comes pull from the sea, reliably they do not slip in and easily to provide a shellfish removal device and shellfish removal method to be raised pull to.

The shell removal device of the present invention is a forced rotation type rotation device that is arranged and fixed on the sea side of the shell removal tool in the shell removal device that pulls the rope with shells out of the sea and removes the shell from the rope with shells by the shell removal tool. comprising a conveyor, and shellfish removal tool to remove the shellfish from shellfish with rope raised can pull a rotating conveyor, a retraction device catching shellfish with rope on board, the rotary conveyor is wound on the outer periphery of the lower rotor and the upper rotating body The net is a conveyor that rotates by the rotation of these rotating bodies, and when the upper rotating body is installed on the ship and the lower rotating body projects obliquely downward toward the sea, the lower rotating body is placed near the sea surface or in the sea. The mesh includes a plurality of meshes arranged in a vertical and horizontal manner and outer peripheries of the outer peripheries of the respective meshes, and the shell removing tool is located above the upper rotary body, and the rotary conveyor The rope of the rope with shellfish that is pulled up on the ship by the rotating and retracting device has a passage that can pass through, and a locking portion that locks the shellfish that is locked to the rope with shellfish without allowing it to pass through and drops off the rope. It is provided.

In the shell removing apparatus of the present invention, the upper rotating body side of the rotating conveyor can be horizontal (including substantially horizontal) and the lower rotating body side can be inclined downward in the shell removing apparatus .

In the shell removing apparatus of the present invention, in the shell removing apparatus, the downward inclination angle to the sea side of the rotary conveyor and / or the protruding length to the outside of the ship can be adjusted .

In the shell removing apparatus of the present invention, in the shell removing apparatus, the rotary conveyor can be accommodated on the ship .

The shell removal method of the present invention is a shell removal method for removing a shell from a rope with a shell using a shell remover while pulling the rope with a shell from the sea. The lower part of the conveyor protrudes diagonally downward from the ship to the sea side and is installed near the sea surface or is placed in the sea, and the rope with the shellfish in the sea runs on the rotary conveyor by rotating the revolving conveyor and pulling in by the retracting device. The rope of the rope with shellfish is passed through the passage of the shell removing tool during the pulling up, and the shell attached to the rope is locked to the locking portion of the shell removing tool. It is a method of dropping from the rope.

The present onset Akira has the following effects.
(1) The rope with shellfish can be pulled up easily and reliably from the sea by the rotation of the rotating conveyor, and the dropout of the shell during pulling is reduced.
(2) Since the sea side of the rotary conveyor is obliquely downward toward the sea, the pulling up from the sea (or underwater) is smooth, and dropping of the shells being pulled up is also reduced.
(3) The conveyor length of the rotary conveyor is longer than that of a conventional drum-shaped pulling rotary body, and the contact length with the rope with shells is longer. Therefore, the friction force between the rope with shells and the rotary conveyor is larger than before. since, it is possible to shellfish with rope'll come smoothly argument is difficult to slip.
(4) Since the angle of descent to the sea side of the rotating conveyor and the descent length (projection length from the ship to the sea side) are variable, it can be adjusted to an angle, length, etc. that are easy to work on, and pulling work can be done It becomes easy to do.
(5) Since the rotary conveyor can be accommodated on the ship, it can be accommodated on the ship so as not to protrude out of the ship when the ship is moved, and does not interfere with the traveling of the ship.

(Embodiment)
An embodiment of a shell removing apparatus of the present invention will be described with reference to FIG. This shell removing device is for removing the shell 1 cultured by hanging the ear from the rope 2, and a case where the shell removing device is mounted on the ship will be described.

(Overview)
FIG. 1 is a side view showing a state where the shell removing device of the present invention is mounted on a ship. The thing shown in this figure is equipped with the rotation conveyor 10, the shellfish removal tool 5, and the drawing-in rotary body 4 in an order from the sea side. Shellfish 1 is farmed been suspended in the sea in a state of being attached to the ropes 2 by the shellfish locking device K, shellfish rope with 3 the shellfish 1 is sufficiently grown is raised Pull from the sea. In this case, shellfish rope with 3 is raised Pull from the sea by the carousel 10 is further raised pull the rope 2 by retractable retraction device 6 in the deck of the ship A. The shell 1 of the rope 3 with shells is removed from the rope 3 with shells by the shell removing tool 5 provided between the rotary conveyor 10 and the retractable rotating body 4 and is stored in the storage basket D installed on the deck. . The accommodated shellfish 1 is washed, sorted by size, and shipped. Below the shell removing tool 5, a downwardly inclined receiving body (for example, a sheet, a net, a plate, etc.) C is arranged toward the deck side, and the shell 1 dropped from the rope 3 with shells is received by the receiving base C once. Then, it slides on the cradle C and is securely accommodated in the accommodation basket D.

(Rotating conveyor)
As shown in FIG. 1, the carousel 10 is wound around the outer periphery of both of the rotating bodies by winding around the rotating body 10a of the starting side (downward: sea side), the rotating body 10b of the end point (upward: ship side), and these rotating bodies. And an endless carrier 10c that rotates. The rotary conveyor 10 is attached to the ship A with the starting-side rotating body 10a inclined downward toward the sea surface, and as an example, the rotary conveyor 10 is attached to a kaising 11 of the ship A by a support material 12. The support member 12 is a rigid arm that can support the rotary conveyor 10 in a downward inclination, and the inclination angle and the position of the starting point side rotating body 10a can be raised or lowered.

  In FIG. 1, the starting point side rotating body 10a is located above the sea surface, but the starting point side rotating body 10a can also be arranged in the sea. The closer the origin-side rotating body 10a is to the sea surface (or the deeper it is in the sea), the longer the endless transport body 10c becomes, and the larger the contact area (length) between the rope 3 with shells and the endless transport body 10c ( Long), the frictional force is increased, and the rope 3 with shellfish is difficult to slip. The length of the endless transport body 10c is shortened as the starting side rotating body 10a is separated upward from the sea surface, and the rotary conveyor 10 is downsized. The position of the starting-side rotating body 10a, that is, the extension of the endless transport body 10c can be designed as appropriate in consideration of the work situation and expenses. When the length of the endless transport body 10c is increased, an intermediate rotating body (not shown) is provided between the two rotating bodies separately from the starting-point side rotating body 10a and the end-point side rotating body 10b. Rotation can also be assisted.

Both or one of the starting point side rotating body 10a and the end point side rotating body 10b can be forcedly rotated by a driving device such as a motor, and when one is forcedly rotated, the other can be freely rotated. The endless transport body 10c circulates and rotates around the outer periphery of the starting point side rotating body 10a and the end point side rotating body 10b at both ends. Rotating direction of the end point side rotating member 10b is to bring can pull the shellfish rope with 3 from the sea, that although the figure is intended to rotate clockwise, shellfish rope with 3 contingencies such as entangled in the retracted rotator 4 In addition, it is desirable to allow reversal (counterclockwise in the figure) when necessary.

  The rotary conveyor 10 is a chain conveyor in which each of the starting-side rotating body 10a and the ending-side rotating body 10b is a sprocket, the endless transport body 10c that rotates on the outer periphery thereof is a chain belt, and a wire mesh is stretched on it. You can also. In the case of a sprocket, without using a chain belt, a belt of a corrugated net, which will be described later, is used for the endless carrier 10c, the space of the corrugated net is hung on the sprocket, and the corrugated net is rotated by the sprocket rotation. You can also Each of the rotating bodies 10a and 10b can be a roller, and a belt conveyor can be wound around the roller.

  The starting point side rotating body 10 a is rotatably supported by the arm 13. One end of the arm 13 is attached to the rotating shaft or the rotating bearing of the starting point side rotating body 10a, and the other end is mounted to the rotating shaft or the rotating bearing of the end point side rotating body 10b. It is installed on both outer sides (the front side and the back side in FIG. 1) of 10b. The arm 13 may be installed only on one of the side surfaces (front side or back side in FIG. 1) as long as it can support the starting side rotating body 10a.

  The arm 13 is rotatably mounted around the end point side rotating body 10b, and the rotary conveyor 10 can rotate about the axis 10d of the end point side rotating body 10b as a rotation axis as shown in FIG. When the operation is not performed, the carousel 10 can be rotated (clockwise in this case) until it is in a substantially vertical posture and stored in the ship.

(Endless carrier)
The endless transport body 10c in FIG. 1 is bent in a substantially U shape, but may be linear. The rope 3 with shells can be rotated in a curved shape as shown in FIG. 1 so that the vertical posture suspended in the sea can smoothly shift to the horizontal posture in the ship. When the endless transport body 10c is rotated in a curved shape, the extension of the endless transport body 10c becomes longer than in the case of the linear shape, the frictional force between the rope 3 with shells and the endless transport body 10c is improved, and the rope 3 with shells slips. It also has the effect of becoming difficult.

  When the endless transport body 10c is rotated in a curved shape, a curve that bends downward as shown in FIG. 1 for the purpose of bringing the rotation direction of the endless transport body 10c on the sea side (left side in the figure) closer to the vertical posture of the rope 3 with shellfish. Shape. Specifically, the endless transport body 10c reciprocates between the starting side rotating body 10a and the end side rotating body 10b, but when rotated in a curved shape, the forward path (referred to as “upper side surface” for convenience) and the return path (for convenience). For convenience, the curvature (referred to as “lower surface”) is different in curvature (representing the degree of bending by the reciprocal 1 / r of the curve radius r), and the curvature of the upper surface is made smaller than the curvature of the lower surface (a gentle curve). And it becomes the curve shape which bends to the side like FIG. In other words, if the upper side is a so-called outer curve and the lower side is an inner curve, the result is as shown in FIG.

  Since the lower surface of the endless transport body 10c tends to hang down due to gravity, the endless transport body 10c rotates in a state where the flexural tension is lost. In order to prevent this, a support 14 shown in FIG. 1 is provided. The support body 14 has a shape that matches the curvature of the lower side surface of the endless transport body 10c, and is disposed below the lower side surface of the endless transport body 10c. Not fixed). In addition, although the support body 14 may be arrange | positioned so that the lower surface of the support body 14 and the endless conveyance body 10c may contact, since the installation purpose of the support body 14 is to prevent the deflection | deviation by drooping of a lower surface, The support body 14 may be disposed with a slight gap between the support body 14 and the endless transport body 10c. The support 14 can be formed using various materials such as resin and metal. However, the support 14 is intended to prevent loosening of the lower surface of the endless transport body 10c, and therefore, a rigid one is suitable.

(Anti-slip protrusion of endless carrier)
The surface of the endless transport body 10c is preferably provided with a non-slip protrusion and a non-slip space. As an example of those, the endless transport body 10c of the rotary conveyor 10 is a corrugated net 15 as shown in FIG. Is wound around the outer periphery of the starting point side rotating body 10a and the end point side rotating body 10b so as not to slip. The wavy network 15 is a wave plate 16 having a bending wave crests and wave troughs in the shape of the narrow plate co shown in FIG. 4 (b), stop projections (outer periphery) sliding wave crests and wave troughs, which are repeatedly formed 18a The inner part of the mountain and the inner part of the valley are made into a non-slip space (mesh) 18b, and a large number of corrugated plates 16 are arranged in a row in the same direction as shown in FIG. In FIG. 3, it is connected in a freely rotating manner at 19 and can be bent following the curved surface portion (rotating portion) of the rotary conveyor 10 as shown in FIG. The corrugated plate 16 and the connecting shaft 19 constituting the corrugated net 15 can be made of metal, resin, or the like, but when made of metal, it is desirable to use rust prevention or stainless steel for use in the sea. . The shape of the anti-slip protrusion 18a and the anti-slip space 18b is not limited to a U-shape, and may be a semicircle, a triangle, or a pentagon. The corrugated net 15 can be formed of a bar material or a pipe material, in particular, a square bar or a square pipe in addition to a plate material.

  When the endless transport body 10c of the rotary conveyor 10 is a belt conveyor, the corrugated net 15 can be attached to the surface of the belt, or when the rotary conveyor 10 is a chain conveyor, it is attached to the chain belt, and the non-slip space 18b can be engaged with the sprocket.

In the conventional drum-type pulling rotator B (FIG. 9 (a)), in the case of the rope 3 with shellfish to which a large amount of miscellaneous material such as Zaraboya has adhered, the rope 3 with shellfish slips on the trunk of the pulling rotator B. Although there are cases where not may be pulled to the rotating conveyor 10, for example a number of slip projections 18a due to the wave crests and wave troughs, as shown in FIG. 3, slip space inside the inner and wave trough of the wave crests of the present invention Since the wavy net 15 provided with 18b is used to form a non-slip structure, the foreign matter adhering to the shells 1 and 2 of the rope 3 with shells enters the anti-slip space 18b (falls down) ) The rope 3 with shells can be easily locked to the anti-slip protrusion 18a, and can be pulled up reliably.

  As another example of the anti-slip projection provided on the surface of the endless transport body 10c and the anti-slip space, the one shown in FIG. 5A is a convex anti-slip projection as shown in FIG. 5B on the surface of the endless transport body 10c. 20 is fixed in a staggered arrangement, and a convex anti-slip space 21 is provided between the convex anti-slip projections 20. The convex anti-slip protrusion 20 can be fixed to the surface of the endless transport body 10c with a stopper such as a screw, a nail, or an adhesive. This convex anti-slip space 21 is also used for facilitating engagement of the shell-suspended rope to the convex anti-slip projection 20 by shellfish, miscellaneous matters, etc. falling.

  The convex anti-slip protrusion 20 and the convex anti-slip space 21 can also be formed on a sheet or thin plate 22 as shown in FIG. Further, as shown in FIG. 6B, a sheet or thin plate 22 provided with a large number of convex anti-slip projections 20 and convex anti-slip spaces 21 is attached to a belt or chain belt. The endless transport body 10c can be formed as in a).

  As another example of the non-slip projection provided on the surface of the endless transport body 10c and the anti-slip space, FIG. 7A shows a V-shaped non-slip projection 23 provided on the surface of the endless transport body 10c as shown in FIG. 7B. Are mounted in a staggered arrangement, and a V-shaped non-slip space 24 is provided between the V-shaped non-slip projections 23. In this case, when the opening side 23a of the V-shaped non-slip projection 23 is attached toward the direction of rotation of the rotating body (the direction indicated by the arrow Y in FIG. 7A), the rope 3 with shells is engaged with the V-type non-slip projection 23. It becomes easy to stop. As shown in FIG. 7 (b), the V-shaped non-slip projection 23 has a mounting piece 23b at the bottom, and the mounting piece 23b is fixed to the surface of the endless transport body 10c with a fixture such as a screw, a nail, or an adhesive. Can be fixed to. The V-shaped anti-slip protrusion 23 may be attached in the direction opposite to that shown in FIG.

  As another example of the non-slip protrusion provided on the surface of the endless transport body 10c and the anti-slip space, FIG. 8A shows an L-shaped non-slip protrusion 25 as shown in FIG. 8B on the surface of the endless transport body 10c. The L-type non-slip space 26 is provided between the L-type non-slip projections 25. As shown in FIG. 8 (b), the L-shaped non-slip protrusion 25 has a mounting piece 25a at the skirt, and the mounting piece 25a is fixed to the surface of the endless transport body 10c with a fixing tool such as a screw, a nail, or an adhesive. Can be fixed to.

.
(Shellfish removal stopper)
A shell removing tool 5 is disposed on the downstream side of the end-point-side rotating body 10b of the rotary conveyor 10 in FIG. The shell removing tool 5 has a ring shape that is not closed (partially opened), and the passage 5a provided inside the ring has an inner diameter that allows the rope 2 to pass through, but the shell 1 cannot pass through. This is the inner diameter. Therefore, when the rope 3 with the shellfish 1 with the shellfish 1 passes through the shell removal tool 5, the locking portion 5 b outside the passage 5 a is obstructed (hooked) by the shellfish 1 on the downstream side. Although it cannot proceed, the rope 2 continues to move to the downstream side, so that the shellfish 1 is pulled off from the shellfish stopper K inserted in the rope 2 and detached from the rope 2. The shellfish 1 is detached from the rope 2 together with the shellfish fastener K in some cases.

The shell removing tool 5 may be U-shaped as shown in FIG. The U-shaped shell removing tool 5 also has a passage 5a. The width of the passage 5a is wide enough to allow the rope 2 to pass through, but the shell 1 has a width that cannot be passed due to being caught by the locking portion 5b of the shell removing tool. It has become. As a result, the shell 1 can be detached from the shell-attached rope 3 in the same manner as the shell remover 5.

(Retraction rotary)
As shown in FIG. 1, a retracting device 6 capable of retracting the rope 2 from which the shells 1 have been removed is disposed on the downstream side (on board) from the shell removing tool 5. Although the drawing device 6 of FIG. 1 includes the drawing rotating body 4 and the pressing tool 7, the pressing tool 7 may not be provided. The retracting device 6 pulls the rope 2 and removes the shells 1 from the shell-attached rope 3 with the shell removing tool 5, and pulls the empty rope 2 from which the shells 1 have been removed in the downstream direction, that is, on the deck of the ship A. As shown in FIG. 9B, the drawing rotor 4 is a drawing in which two disks 4a and 4b are arranged opposite to each other and connected by a connecting shaft 8 to guide the rope 2 between the two disks 4a and 4b. A passage 4c is formed. The drawing-in passage 4c is narrow at the center (the connecting shaft 8 side) of the two discs 4a and 4b and wide at the outer peripheral side. Since the rope 2 cannot be retracted only by the retraction rotator 4, the pusher 7 is provided so as to face the retraction passage 4c of the retraction rotator 4 in order to ensure that the rope 2 can be retracted, and the retraction passage 4c. The rope 2 drawn in can be held between the drawing rotary body 4 and the pusher 7. In this case, in FIG. 1, the rope pusher 7 rotates (clockwise) so as to pull the rope 3 with shells onto the ship, and the pusher 7 rotates counterclockwise. The shell removing tool 5 (FIG. 1) can also be installed on the pull-in rotating body 4. The shapes, structures, etc., of the drawing rotor 4 and the pusher 7 of the drawing device 6 may be other than those shown in FIG.

  Below the pusher 7, a rope flip 9 for preventing the rope 2 from biting into the retractable rotary body 4 is provided. This rope flip 9 plays so that the rope 3 with shells drawn between the pull-in rotating body 4 and the pusher 7 does not bite into the pull-in rotating body 4. Since the drawing passage 4 of the drawing rotor 4 is narrowed from the outer peripheral side to the center side of the two disks 4a and 4b as shown in FIG. 9B, the rope 2 drawn into the drawing passage 4c is drawn. Cut into the center of the passage 4c. Since the rope 2 may become difficult to move when it is bitten deeply, the rope flipper 9 prevents excessive biting and makes an appropriate push so that the rope 2 can be continuously drawn smoothly. belongs to. As shown in FIG. 9B, the rope flipper 9 has a distal end portion 9a having a tapered wedge shape, and the distal end portion 9a is disposed in the retracting passage 4c. With this configuration, as shown in FIG. 9B, the rope 2 passes through the drawing passage 4c in the upper portion of the drawing passage 4c. Since the rope flip 9 is disposed at a position where the rope 2 passes, the rope 2 cannot enter the center side of the drawing passage 4c of the drawing rotating body 4 and does not wind around the connecting shaft 8, and the drawing passage 4c. Sent out of the.

  As shown in FIG. 2, the drawing-in rotating body 4 can be installed so as to rotate on a horizontal plane. In this case, the pusher 7 is similarly arranged so as to rotate on a horizontal plane, and the rope flipper 9 is installed downstream of the pusher 7 (the moving direction of the rope 2: the right side in FIG. 2).

(Example of use)
