Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to paper, non-woven fabric, cloth,
The present invention relates to an improvement in an apparatus for producing a twisted string by applying a twist using a tape of a synthetic resin or the like as a raw material.

[Prior art]

[0002] As a prior art of the apparatus for producing a twisted string-like article of the present invention, JP-A-9-141764 can be mentioned. The outline of this apparatus and the twisted string produced by the apparatus will be described below with reference to FIGS. A supply roll 3 of a raw material tape 2 is horizontally mounted on the fixed frame 1 so as to be rotatable in a horizontal state. A rotating frame 4 is provided below the rotating frame 4 so as to be rotatable by a motor 5. A tension roller 6 and a twist applying means 7 are provided for the rotating frame 4. As shown in FIG. 5, the twist imparting means 7 twists one end in the width direction of the raw material tape 2 toward the other side and deviates the axial direction of each other so as to cause a winding phenomenon. And the deviation rollers 7a and 7b. With the rotation of the rotating frame 4, the tension roller 6 and the eccentric rollers 7a, 7
By rotating b and pulling by the take-up means 9,
A twist is added to the raw material tape 2 to form a twisted string material 8, which is wound by a winding means 10.

[0003] In order to increase the production amount with the existing apparatus for manufacturing a twisted string, in the case of an apparatus as disclosed in Japanese Patent Application Laid-Open No. H09-117164, when the production speed is 40 m / min, it is necessary to use a tape. The applied tension was 1.7 to 1.9 kgf / cm, and in the case of paper tape, it was in the cutting limit area. Therefore, no further increase in production could be expected.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been studied to increase the production amount more than before without causing tape breakage in the apparatus for manufacturing a twisted string. That is, an object of the present invention is to enable a high-speed (for example, 50 to 80 m / min) high-speed production rate of a twisted cord-like material, which has not been conventionally possible.

[0005]

As a result of examining the above-mentioned problems, it is found that, in a manufacturing apparatus of a twisted string-like material which is formed into a twisted string by a twist applying means while supplying a raw material tape and wound by a product winding roller, a twist is applied. The tape feeding means was provided to the raw material tape supply side before the means.

[0006] As an example of the tape feeding means, a tape feeding roller interlocked with the rotation drive of a rotating frame holding the twist applying means can be shown. As a specific example of the mechanism that is linked to the rotation drive of the rotating frame, a structure in which the rotation of the rotating frame is used as a rotation drive source of the tape feed roller by a bevel gear is suitable. There is a feature that the tape can be completely fed by the tape feed roller because it is mechanically linked by the bevel gear.

As another tape feeding means, a structure in which a tape feeding roller is rotated by a motor provided independently and independently of the rotation of the rotating frame can be shown. In this case, the synchronization of the tape feed speed is performed by controlling the rotation speed of the motor. Recently, many kinds of high-precision ones are commercially available, so that it can be implemented. For example, a servo motor is mounted on a rotating frame to rotate a tape feed roller. The weight balance during rotation of the rotating frame can be solved by providing a balancer on the side symmetrical to the motor. By providing a current collecting terminal such as a slip ring, power can be supplied to the motor even if the entire motor rotates together with the rotating frame.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of an apparatus for manufacturing a twisted string according to the present invention, and FIG. 2 is a side view.

[0009] The supply roll 3 of the raw material tape 2 is mounted horizontally on the fixed frame 1 so as to be rotatable in a horizontal state, as in the above-mentioned Japanese Patent Application Laid-Open No. 9-111764. A rotary frame 4 is provided coaxially below the rotary frame 4 so as to be rotatable by a motor 5, and twisting means 7 is provided for the rotary frame 4. As described above, the twist imparting means 7 twists one end in the width direction of the raw material tape 2 toward the other side, and deviates the axial direction of each other so as to cause a winding phenomenon. It consists of position rollers 7a and 7b.

In the present invention, a mechanism for increasing the production speed is used in order to increase the production amount in the apparatus for producing a twisted string. That is, a tape feed roller 11 is provided as a tape feed unit, which is interlocked with the rotational drive of the rotating frame 4 that holds the twist applying unit 7. As a mechanism for linking the tape feed roller 11 with the rotation drive of the rotary frame 4, the rotation of the rotary frame 4 is configured to be a rotation drive source of the tape feed roller by bevel gears 12 and 13. That is, the left and right two vertical rotating bevel gears 12 and 12 supported by the rotating frame 4 are engaged with the horizontal fixed bevel gear 13 fixed to the horizontal frame 1a of the fixed frame 1, and the rotation of the rotating frame 4 The vertical rotating bevel gears 12, 12 are configured to rotate.

The pulleys 14, 14 are coaxial with the vertically rotating bevel gears 12, 12.
The timing belts 16, 16 are stretched between the pulleys 14, 14 and the pulleys 15, 15 provided coaxially with the tape feed roller 11. Note that torque controllers 17, 17 are provided between the tape feed roller 11 and the pulleys 15, 15. Bevel gears can be used to mechanically link the tapes for complete tape feed.Torque controllers 17 and 17 eliminate tension unevenness, smooth twisted cords, improve quality and reduce tape cutting troubles. Becomes When the tension roller 6 and the eccentric rollers 7a and 7b of the twist applying means 7 rotate in conjunction with the rotation of the rotating frame 4, the raw material tape 2 is twisted to form a twisted string 8 and the take-up means 9 While being taken up by the winding means (not shown). Even if the winding speed of the twisted string is increased, the tape feed roller 11 forcibly feeds the tape to be pulled more than the breaking strength of the tape,
Tape breakage can be prevented. At this time, it is more effective if the tension roller 6 is urged by a spring so as to play the role of bringing the raw material tape 2 into close contact with the tape feed roller 11.

FIG. 3 is a front view of another embodiment of the present invention. In this example, a motor 18 is connected to a tape feed roller 11 provided on the rotating frame 4. The rotation of the motor 18 is controlled by the electric control means, and the raw material tape 2 is tuned to the twisting speed and optimized, thereby enabling a high production speed of a twisted string of 50 to 80 m / min. Rotating frame 4
Roller 6 and twist applying means 7 accompanying rotation of
The rotation of the eccentric rollers 7a and 7b causes the raw material tape 2 to be twisted to form the twisted string-like material 8 in the same manner as in the previous examples. Reference numeral 19 indicates a sliding type current collecting terminal
(Slip ring), and reference numeral 20 denotes a balancer for balancing with the motor. In this example,
Even if the winding speed of the twisted string is increased, the tape feeding roller 11 forcibly feeds the tape when it is pulled beyond the breaking strength of the tape, thereby preventing tape breakage.

[0013]

According to the present invention, it has become possible to increase the production amount as compared with the prior art without causing tape breakage in the production of a twisted string. This has made it possible to reduce the production cost of the twisted string and provide a high-quality product.
