Apparatus 1 for manufacturing synthetic resin rope according to the present invention
Since it has the above-described structure, the synthetic resin rope manufacturing apparatus 1 is used to form a synthetic resin tape of a predetermined width around a cylindrical paper core material 33a as shown in FIG. A material 33 formed by stacking 33b in multiple layers,
A reinforcing material 35b such as wire, paper or tape around the core material 35a
When manufacturing a high-strength synthetic resin rope of a type in which the synthetic resin tape 33b and the reinforcing material 35b are twisted in a double spiral shape from the reinforcing body 35 formed by winding the Follow the same procedure.

That is, first, the material holding screw 13 of the synthetic resin rope manufacturing apparatus 1 shown in FIG. 1 is removed, and the core material 33a of the material 33 is inserted from the upper end of the first shaft 5 to insert the material 3 into the material 3.
Place 3 on table 3. In this state, the material pressing screw 13 is attached to the male screw portion 5a of the first shaft 5, and the material 33 is fixed so as to be pressed onto the table 3. In the same manner, the reinforcement body holding screw 16 is removed, and the second shaft 1
The core material 35a of the reinforcing body 35 is fitted from the upper end of 5 and the reinforcing body 35 is placed on the table 3. In this state, the reinforcing body holding screw 16 is attached to the male screw portion 15a of the second shaft 15. , The reinforcing member 35 is fixed to the table 3 by pressing it.

In this way, when the material 33 and the reinforcing body 35 are placed on the table 3 in a fixed manner, the material 3
One end of the synthetic resin tape 33b of No. 3 has two guide bars 1
The guide ring portions 19a, 19a at the left end of FIG.
Via pinch rolls 20, 21, 26, 28 and 27,
It is sandwiched between the driven roller 32 and the drive roller 31 in the two upper and lower stages of the drawing device 30, and is further attached to the winding core 29b of the winding machine 29. In addition, the reinforcing material 35 of the reinforcing body 35
One end of b is passed through the guide ring portion 19a at the left end of the guide bar 19 on the lower side of FIG. 1 so as to be along the synthetic resin tape 33b of the material 33.

Next, the first motor 7 is driven to move the table 3 around the shaft center CT1 in the direction of arrow M in FIG.
(The direction in which the synthetic resin tape 33b is wound) is driven, the second motor 23 is driven to rotate the drive roller 31 of the drawing device 30 in the direction of arrow C, and the winding core 29b of the winder 29 is further rotated. Rotate in the direction of arrow Q or R around the center CT2. Then, the material 33 and the reinforcing body 35 on the table 3 are rotated in the direction of the arrow M about the axis CT1 and the synthetic resin tape 3 of the material 33 is rotated.
It is wound up on 3b. At this time, paying attention to the portion of the synthetic resin tape 33b located immediately above the material 33 on the table 3, the portion of the synthetic resin tape 33b rotates in the direction of arrow M about the axis CT1 and is pulled upward at the same time. From the above, in the state of being twisted into a rope shape, that is, the guide ring portion 1 of the guide bars 19 and 19.
9a, 19a and pinch rolls 20, 21, 26, 28 and 27. In addition, by appropriately adjusting the speed adjuster 12 connected to the first motor 7, the ratio between the rotation speed of the table 3 and the rotation speed of the drive roller 31 (that is, the pulling speed of the synthetic resin tape 33b) is changed. Thus, the degree of twist of the synthetic resin tape 33b can be set appropriately. That is, if the ratio of the rotation speed of the drive roller 31 to the rotation speed of the table 3 is reduced, the degree of twist of the synthetic resin tape 33b becomes dense, and conversely the ratio of the rotation speed of the drive roller 31 to the rotation speed of the table 3 is increased. Then, the degree of twist of the synthetic resin tape 33b becomes rough. On the other hand, the reinforcing material 35b of the reinforcing body 35 advances along the same path so as to be drawn into the rope-shaped synthetic resin tape 33b (that is, the synthetic resin rope). As a result, the synthetic resin tape 33b and the reinforcing material 35
The synthetic resin rope in which b and the double helix are twisted, that is, the high-strength synthetic resin rope advances along the same route.

Then, the heater 25 is operated to heat the high-strength synthetic resin rope passing between the pinch roll 28 and the pinch rolls 26 and 27. Then, the outer peripheral surface of the synthetic resin rope is welded so that it cannot be melted again. The high-strength synthetic resin rope thus produced is wound around the winding core 29b of the winding machine 29. When the high-strength synthetic resin rope is wound up by a predetermined length, the manufacturing process of the high-strength synthetic resin rope is completed.

In the embodiment described above, as shown in FIG. 1, the material 33 and the reinforcing body 35 are placed side by side on the table 3, but the material 33 and the reinforcing body 35 are different from each other. It is not always necessary to place them side by side. For example, in FIG.
As shown in FIG. 1, the core material 33a of the material 33 is attached to the first shaft 5.
The core material 35a of the reinforcing body 35 is inserted into the first shaft 5 to mount the reinforcing body 35 on the material 33, and then the first shaft 5
Attach the material holding screw 13 to the male screw part 5a of the
It is also possible to manufacture the high-strength synthetic resin rope in the same procedure by fixing 3 and the reinforcing body 35 to the table 3 in a pressed manner.

Further, in the above-mentioned embodiment, the production of the high-strength synthetic resin rope of the type in which the synthetic resin tape 33b and the reinforcing member 35b are twisted in a double spiral shape has been described. Reinforcing material 35b in tape 33b
It is also possible to manufacture a high-strength synthetic resin rope of a type (so-called core-insertion type) in which is inserted. In this case,
Instead of the round rod-shaped (that is, solid) first shaft 5 of the synthetic resin rope manufacturing apparatus 1 shown in FIG. 1, a cylindrical (that is, hollow) shaft 5 ′ as shown in FIG. 5 is used. Hereinafter, the synthetic resin rope manufacturing apparatus 1 including the cylindrical shaft 5 ′ will be described. However, only the structure near the cylindrical shaft 5 ′ is different, and the description of the other parts will be omitted. .

That is, as shown in FIG. 5, a cylindrical shaft 5'is fixed to the center of the table 3 so as to penetrate in the directions of arrows A and B, and the guide rod 37 is attached to the shaft 5 '.
Are fixed to the table 3.
At the tip of the guide rod 37, a guide ring 37a is mounted on the table 3, and the synthetic resin tape 33 of the material 33 is mounted.
The spring 37 is located at a substantially central portion in the width direction of b.
It is provided to be extendable and contractible in the radial direction of the table 3 by b.

Therefore, when the synthetic resin rope of the core type is manufactured by using the synthetic resin rope manufacturing apparatus 1 provided with the cylindrical shaft 5 ', the above-mentioned synthetic resin tape 33b and the reinforcing member 35b are used. The manufacturing procedure is the same as in the case of the double-twisted type synthetic resin rope. However, the reinforcing body 35 is installed below the table 3 and
As shown in FIG. 5, the reinforcing member 35b of No. 5 is inserted into the cylindrical shaft 5 ′ and then hooked on the guide ring 37a of the guide rod 37. Then, the reinforcing material 35b is inserted into the spirally twisted synthetic resin tape 33b, and a core-type high-strength synthetic resin rope is completed. The material 33 becomes thinner as the synthetic resin tape 33b is unwound from the material 33, but the guide ring 37a of the guide rod 37 is moved by the spring 37b in the radial direction of the table 3 (and thus in the radial direction of the material 33). Since it is provided to be expandable and contractible, it is always kept in contact with the synthetic resin tape 33b, so that the cored type high-strength synthetic resin rope can be smoothly manufactured.

When used in applications where strength is not required, ordinary synthetic resin rope can be used without using the reinforcing material 35b. In this case, the second one shown in FIG.
Since the shaft 15 and the reinforcing body pressing screw 16 are unnecessary, the above-mentioned high-strength synthetic device is used by using the synthetic resin rope manufacturing apparatus 1 without the second shaft 15 and the reinforcing body pressing screw 16 as shown in FIG. An ordinary synthetic resin rope can be manufactured by the same procedure as that for the resin rope. The synthetic resin rope manufacturing apparatus 1 has the same structure as the synthetic resin rope manufacturing apparatus 1 described above except that the second shaft 15 and the reinforcing body holding screw 16 are not provided. , The same reference numerals are given to the same portions, and the description thereof will be omitted.
