Description

[Detailed explanation of the idea] The present invention relates to a rope reeling machine.

A battery winch 1' as shown in Fig. 1 is used to pull up anchors used in small vessels, leisure vessels, boats, etc. That is, the battery winch 1' is installed on the ship side and the battery wiring is connected. When using the anchor, place the anchor rope on the upper surface of the roller 2', turn the switch on and rotate the roller 2', and use the frictional force between the rope and the roller 2' to pull it up with easy force. The goal is to make it possible for people to do so. However, since it is necessary to always hold the rope by hand and pull it by hand, it is impossible to take one's hands off the rope until the end, which does not solve the troublesome work. Additionally, the longer the rope length, the more fatigue your hands and arms will experience.

The present invention aims to solve the above-mentioned problems, and its characteristics are that the roller is divided near the outer edge to form a main body part and a flange body part, and there is a space between them that is approximately the same as the diameter of the rope. At the same time, a groove gap is formed and a ball bearing is interposed, and a main rod of a certain length, a ring fitted on the outer ring, and a ring smaller than the main rod are placed on the outer ring which is the stationary side of the ball bearing. A guide rod consisting of a secondary rod and a secondary rod with the same dimensions is installed, and the hand side of the rope wound on the roller is guided into the passage formed by the main rod and secondary rod, and pulled upward from the opposite side of the roller. The reason is that automatic winding is performed by winding the wire half a turn within the groove gap.

An example of an embodiment of the present invention will be described below based on the drawings.

Fig. 2 is an overall perspective view of the device of the present invention, Fig. 3 is a perspective view of parts of the guide rod used in the device of the present invention, Fig. 4 is a partial sectional view of the main parts, and Fig. 5 is a diagram of the state in use. .

Reference numeral 1 is a device of the present invention in which, compared to conventional products, a roller 2 is separated near its outer edge to form a groove 3 into which a rope can be inserted, and a guide rod 14 is interposed within the groove 3.

To explain this specifically, the roller 2 consists of a main body part 2a around which the rope 5 is wound two or three times, and a collar body part 2b forming an edge.The collar body part 2b has a roller shaft 6 in the center. A boss 7 having a constant width S is formed into which the boss 7 is fitted. Thus, a key step 8 is formed on the side edge of the collar body of the boss 7, and an annular recess 9 is bored in the collar body portion 2b, with the key step 8 forming one side edge thereof. Become. On the other hand, a similar concave body 10 is bored on the main body part 2a side corresponding to the concave body 9, and 11 is a key on the main body part 2a side.

Reference numeral 12 denotes a ball bearing disposed between the recesses 9 and 10, and the inner ring seat 1 of the bearing
The key 2a is held between the two keys 8 and 11 and is rotated with the rotation of the roller shaft 6.
The outer ring seat 12c is not rotated via the balls 12b. Note that 13 is a nut to which the tip of the roller shaft 6 is screwed, and is pressed and fixed so that the collar body part 2b rotates as one with the roller main body part 2a.

On the other hand, 14 is a guide rod, which is a main rod 14a of a certain length l necessary for engaging with a locking bar described below, a ring 14b that can be fitted onto the outer ring seat 12b of the ball bearing 12, and ring 14b
The main rod 14a is short in size and has a sub-rod 14c that protrudes approximately parallel to the main rod 14a.In order to install the sub-rod 14c, the ball bearing 12 is fitted around the outer periphery of the boss 7 with the collar body 2b removed from the roller shaft 6. and the outer ring seat 12c of the ball bearing 12.
The ring 14b of the guide rod 14 is fitted onto the top, and in this state it is inserted into the roller shaft 6 and fixed via the nut 13. At this time, a groove gap 15 having a V-shaped cross section is formed between the side edge e of the main body part 2a of the roller 2 and the side edge f of the collar body part 2b. The lowest dimension H is designed to be equal to or less than the diameter d of the rope 5 used. Now, if the diameter of the rope 5 becomes large, it will be necessary to increase the groove gap 15 accordingly, but in this case, the keys 11, 8 and the inner ring seat 1
This requirement can be easily met by inserting a washer ring (not shown) of an appropriate thickness between the holder and the holder 2a.

On the other hand, 16 is the roller 2 from the base F of the device main body.
This is a locking bar that protrudes toward the side.

Next, its effect will be explained. When the guide rod 14 is attached to the roller 2, the secondary rod 14c
The tip is returned to the main body 2a side a little, so that a passage 17 into which the rope 5 is introduced is formed between it and the main rod 14a. On the other hand, the rope 5 is connected to the roller 2
The rope 5 on the hand side is wound two or three times in the same direction as the rotational direction of the roller 2, that is, in the direction of arrow A in the illustrated example, and the rope 5 on the hand side is wound on the main body 2a of the main body 2a. A passage 1 formed between the main rod 14a and the sub-rod 14c of the guide rod 14 at the end edge.
7, and then the side end e of the main body part 2a and the collar body part 2b.
The roller 2 passes through the groove gap 15 with the side edge f of the roller 2.
Pull it upwards from the opposite side and wrap it half a turn.

On the other hand, the tip of the main rod 14a of the guide rod 14 is engaged with the tip of the locking bar 16, so that the rotation of the roller 2 does not cause the guide rod 14 to move in the direction of rotation of the roller.

Now, when the switch is turned on and the motor is driven in the above state, the rope 5 will be automatically hoisted up even if the hand is not released by the rotation of the roller 2 in the direction of arrow A, and the hoisted rope will be When the rod 5 passes through the groove gap 15, it is separated from the position above the main rod 14a and hangs down, and is stored in a box or the like below as appropriate. In the above embodiment, a case has been described in which a box is provided directly below the rope to store the rope, but a guide roller may be provided as appropriate and the rope may be stored in another location as a guide. Further, in order to increase the frictional resistance of the rope 5 passing through the groove gap 15, it is also possible to appropriately apply corrugation to the opposing surfaces within the groove gap.

According to the present invention, the rope 5 is automatically hoisted and does not require any manual hoisting work. In addition, after hoisting the anchor, stop driving the motor.
The coiled rope is removed from the roller surface and from within the groove, and when the anchor is reused, it is immediately dropped into the sea as is.

The device of the present invention is convenient because it does not require any manual reeling work, and since the rope is reeled out in an orderly manner, it can be reeled out easily without becoming tangled. The present invention can be conveniently used for hauling up fishing nets, and is within the scope of implementation of the present invention.
