Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention stabilizes a wire (including an optical fiber), a wire, a rope, a string, a hose, a tube, a tape, a band, a strip, and the like. The present invention relates to a striated body supply device for supplying with a predetermined tension. [0002] Generally, the above-mentioned filaments are twisted, wound,
When supplying to equipment, equipment, etc. for coating etc., or wiring to equipment, etc., kink, twist, entanglement due to loosening, line elongation due to excessive pulling, disconnection, breakage, etc. may occur It is desirable to supply with an appropriate amount of tension so as not to cause poor quality or difficult supply. Various devices have been proposed and used as such a striatum supply device. As an example, there is a striated body supply device having a configuration shown in FIGS. As shown in FIG. 5, this filament feeder is formed by winding a filament 1 spirally or concentrically (spring-shaped). If necessary, a drum, bobbin, reel or the like is formed. A filament wound body 3 held by the winding frame 2;
A disk-type auxiliary supply brake unit that is attached to the upper part of the striated winding body 3 and applies tension to the striated body 1 so that the striated body 1 is not unnecessarily pulled out of the striated winding body 3. 4 and a double capstan type main supply brake unit which is disposed above the auxiliary supply brake unit 4 and applies a predetermined amount of tension to the striated body 1 in accordance with the tension of the auxiliary supply brake unit 4 5 are provided, and a plurality of filaments are provided for each filament 1 supplied to the filament processing equipment (not shown). [0004] Auxiliary supply brake unit 4 of each striatum supply device
As shown in FIG. 6, on the outer peripheral surface of the disk body 6, a bendable, elastic, linear short and long wire (whisker) made of a number of plastic materials such as nylon at short intervals in the circumferential direction. ) 7 projecting in the radial direction. Then, when the filament 1 pulled out from the filament winding body 3 is supplied to the upper main supply brake unit 5 through the space between the short and long wires 7,
A tension is applied to the filament 1 by a braking action obtained by a frictional force generated by coming into contact with the short and long wire 7, so that the filament 1 is not pulled out more than necessary from the filament winding body 3. I have. [0005] The main supply brake unit 5 is shown in FIG.
As shown in (b), a lower capstan 10 and an upper capstan 1 rotatably supported by two capstan shafts 9 provided in a frame 8 and separated in the vertical direction in a horizontal direction.
1 is provided. The lower capstan 10 has a plurality of annular grooves 12 formed on the outer peripheral surface in parallel in the axial direction, and an annular brake groove 13 formed at the base end on the frame 8 side. Upper capstan 11 has lower capstan 1 on the outer peripheral surface.
Zero annular grooves 12 are formed in parallel in the axial direction. [0006] Further, a string 14 for braking is wound around the lower half of the groove 13 of the lower capstan 10 in a U-shape, and one end 14a of the string 14 for brake is retained on the frame 8; The other end 14 b is retained on the frame 8 by the spring 15. Then, a predetermined tension is applied to the string 14 for brake by the spring 15, and a brake is applied to the rotation of the lower capstan 10 by a frictional force with the groove 13 for brake of the lower capstan 10. . The striated body 1 introduced from the auxiliary supply brake section 4 to the main supply brake section 5 is turned obliquely upward while being guided by an annular groove 12 closer to the frame 8 of the lower capstan 10. The capstan 11 is introduced into the annular groove 12 closer to the frame 8. Next, after being wound around the annular groove 12 by 180 degrees or more, the direction is changed obliquely downward and introduced into the annular groove 12 of the lower capstan 10 adjacent to the annular groove 12. Furthermore, after being looped by 180 degrees or more in the annular groove 12, the direction is changed obliquely upward again. In this way, the striated body 1 is sequentially wound around the annular grooves 12 of the lower capstan 10 and the upper capstan 11 while crossing each other. Supplied. [0008] The filament 1 is provided with a tension applied by a braking action obtained by a frictional force caused by the contact of the auxiliary supply brake unit 4 with the short and long wires 7 and a brake for rotating the lower capstan 10 in the main supply brake unit 5. It is supplied at a predetermined tension in which the tension given by the action is combined. In the conventional linear body delivery device, tension is applied to the filament 1 by the auxiliary supply brake unit 4 and the main supply brake unit 5. Each of the short and long wires 7 of the auxiliary supply brake unit 4 has its shape,
Since there are variations in the projecting state and elasticity,
In addition to the fact that the contact state between the wire and the short supply wire 7 of the auxiliary supply brake unit 4 is not constant, the outer surface of the striated body 1 comes into contact with the short supply wire 7 and the outer surface thereof becomes rough, and the contact state with the short supply wire 7 becomes poor. It is easy to change, and with the supply of the filament 1, the frictional force between the two, that is, the braking action on the filament 1 is not constant. The contact state between the filament 1 and each annular groove 12 of the lower capstan 10 of the main supply brake portion 5 also
The outer surface of the striated body 1 is uneven due to bulging by the auxiliary supply brake unit 4 and the smoothness of the surface of each annular groove 12 is not constant. Slip occurs during this time, or the slip state changes easily. Then, with the supply of the filament 1, it is difficult to reliably transmit the braking action of the rotation of the lower capstan 10 to the filament 1. As a result, in the conventional filament supply device, the tension of the supplied filament 1 becomes unstable and the tension is not easily adjusted, so that the filament is supplied with a stable predetermined tension. There was a problem that it was not possible. Also, striatum 1
When passing through the auxiliary supply brake unit 4 and the main supply brake unit 5, the outer surface of the striated body 1 comes into contact with the short and long wire rod 7 and becomes rough, or the capstan 10 of the main supply brake unit 5, There is a problem that fine trauma is formed on the outer surface due to rubbing with 11 and the quality of the supplied striatum 1 is reduced. The present invention has been made to solve the above-mentioned problems, and to provide a filament feeder capable of supplying a high quality filament at a stable predetermined tension without damaging the outer surface of the filament 1. With the goal. [0013] In order to achieve the above-mentioned object, a striated body feeding device according to the present invention comprises a striated body wound and formed to be rotatably supported. A winding body, a brake drum disposed on the side of the filament winding body so as to rotate integrally with the rotation of the filament winding body, and a filament drawn from the filament winding body It has a guide part that guides and supplies the body,
A swing arm that swings in accordance with a change in the tension of the striated body pulled out and supplied from the striated winding body, and swings the swing arm in a direction in which the tension acting on the striated body increases. As described above, a biasing member that is constantly biased and a brake string that is hung around the brake drum, one end of which is fixed, and the other end of which is attached to the swing arm are provided. In the case of supplying a filament using the filament supplying device of the present invention, when the tension of the supplied filament is larger than an appropriate predetermined tension, the swing arm is moved by the urging member. The tension acting on the brake string by swinging in the direction in which the filament is supplied against the bias is reduced. Then, the tightening of the brake drum by the brake string is weakened, the amount of the filament pulled out from the filament winding body is increased, and the tension of the supplied filament is reduced, so that an appropriate predetermined Return to tension. On the other hand, when the tension of the supplied linear body becomes smaller than an appropriate predetermined tension, the biasing force of the biasing member of the swing arm causes the swing arm to be linearly moved by the tension of the linear body. The force is greater than the force that causes the body to swing in the direction in which the body is supplied, and the swing arm is in the opposite direction to that described above, that is, in the direction opposite to the direction in which the body is supplied. In the direction that hinders the supply of oil) and the tension acting on the brake string increases. Then, the tightening of the brake drum by the brake string becomes stronger, the amount of the filament drawn out from the filament winding body decreases, and the tension of the supplied filament increases, and the appropriate predetermined Return to tension.
Therefore, according to the umbilical member supply device of the present invention, the umbilical member can always be supplied with a stable and appropriate predetermined tension. Further, since the filament drawn out from the filament winding body is supplied through the guide portion of the swing arm, the outer surface of the filament comes into contact with the short and long wire rods and becomes rough. Also, fine trauma is not formed on the outer surface by rubbing with the guide portion, and a high-quality striatum can be supplied. Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a right side view showing an embodiment of a striated body supply device according to the present invention, and FIG. 2 is a state in which the striated body is supplied with an appropriate predetermined tension in the striated body supply device of FIG. FIG. 3 is a front view showing a state where the striatum is supplied with a tension greater than the tension shown in FIG. 2, and FIG. 4 is a tension view showing the striatum as shown in FIG. It is a front view showing the state where it is supplied with smaller tension than. In describing the configuration, the same components as those of the conventional device are denoted by the same reference numerals. FIGS. 1 and 2 show a striated body supply device according to this embodiment.
As shown in (1), a wire 1 (including an optical fiber), a wire, a rope, a string, a hose, a tube, a tape, a band, a strip, or the like, is wound spirally or concentrically (spring-shaped). And a filament winding body 3 held by a winding frame 2 such as a drum, a bobbin, a reel, and the like, and a winding frame 2 holding the filament winding body 3
And a brake drum 16 integrally attached to one side of the brake drum. The filament wound body 3 and the brake drum 16
A support shaft 19 rotatably supported by a bearing (not shown) is inserted into a bracket 18 which is separately mounted on the base 17 and is integrally fixed by a fixing key (not shown). Therefore, the filament wound body 3 and the brake drum 16
They rotate in the same direction at the same rotation speed.
When the striated winding body 3 does not have the winding frame 2, for example, the brake drum 16 is attached to a side portion of the striated winding body 3 and disposed. 3 and the brake drum 16 are configured to rotate integrally. Further, a support shaft 19 is provided on the bracket 18 so as not to rotate, and
9, the wire wound body 3 and the brake drum 16 may be rotatably supported. Further, the filament feeder of the present embodiment further includes various facilities for guiding and twisting, winding, coating, etc. the filament drawn from the filament winding body 3. Swinging arm having a guide portion 21 for supplying to a device or the like, and swinging about a spindle 22 following a change in tension of the filament 1 pulled out from the filament winding body 3 and supplied. 20; an urging member 23 attached to the oscillating arm 20 and constantly urging the oscillating arm 20 to oscillate in a direction in which the tension acting on the striatum 1 increases; It is provided with a brake string 24 attached to the swing arm 20 by being turned so that one end 24a is fixed and the other end 24b is attached to the swing arm 20. The guide portion 21 is formed of a guide roll as shown, and is rotatably provided at the tip end of the swing arm 20. The guide portion 21 may be constituted by a guide rod (not shown) instead of the guide roll. The purpose of the guide portion 21 is to guide the striated body 1 and not to apply tension to the striated body 1. Therefore, the outer surface of the striated body 1 is not roughened by the guide portion 21 and is not rubbed with the guide portion 21 to form fine trauma on the outer surface. can do. The support shaft 22 for swinging the swing arm 20
Is fixedly attached to an arm stand 25 erected on the base 17, and the base end (lower end) of the swing arm 20 is rotatably supported on the support shaft 22. In addition,
The support shaft 22 may be fixedly attached to the base end side of the swing arm 20, and the support shaft 22 may be rotatably supported by the arm stand 25 so that the swing arm 20 can swing. The brake cord 24 is made of, for example, a flexible rubber or plastic brake belt containing a reinforcing material.
A lining material having a large coefficient of friction is laminated on a surface that comes into contact with, or an uneven portion that increases frictional force is formed. One end 24a of the brake string 24 is fixed to a string mounting plate 26 erected on the base 17 via a coil spring 27 for tension, and the other end 24b is an intermediate part of the swing arm 20. Part, ie, the support shaft 22 and the guide part 2
1 at any intermediate position. Accordingly, the brake string 1 is applied to the brake drum 1 in a state in which the coil spring 27 applies a tensile force due to elasticity.
6 is wrapped around the outer peripheral surface at an angle of about 180 degrees in the circumferential direction. The coil spring 27 is not located between the one end 24a of the brake cord 24 and the string attachment plate 26, but is connected between the other end 24b of the brake cord 24 and the swing arm 20. Between, or between the one end 24a of the brake string 24 and the string mounting plate 26 and between the other end 24b of the brake string 24 and the swing arm 20, respectively. The brake cord 24 may be wound around the outer peripheral surface of the brake drum 16 in a state where the tensile force due to the elasticity acts on the brake cord 24. Or, without using the coil spring 27, the brake cord body 24 itself is formed of an elastic body that can expand and contract in the longitudinal direction,
Such a cord 24 for a brake is extended in a longitudinal direction by a predetermined amount, and in a state where a tensile force is exerted on the cord 24, the cord 24 is stretched between the cord-like body mounting plate 26 and the swing arm 20, The brake drum 16 may be wound around the outer peripheral surface. In this way, the brake drum 1 is held in a state where the brake cord 24 is subjected to elastic tensile force.
When it is hung around 6, due to a change in the tension of the striatum 1,
The tightening of the brake drum 16 by the brake string 24 does not suddenly become weak or strong.
That is, the amount of the striated body drawn out from the striated winding body does not rapidly increase or decrease. Therefore, it is preferable because the tension of the supplied filament can be controlled more quickly and accurately, and the tension of the supplied filament can be more quickly stabilized. As the urging member 23, a coil spring for tension is used in the drawing. One end of the spring is located at an intermediate portion of the swing arm 20, that is, the support shaft 22.
Is attached to an arbitrary intermediate portion between the guide member 21 and the other end, and the other end is attached to a fixing member (not shown),
The swing arm 20 is always urged to swing in the direction in which the tension acting on the filament 1 increases, that is, in FIG. 1, counterclockwise about the support shaft 22. Although not shown, a torsion coil spring is used as the biasing member 23, and this spring is
2 is fitted coaxially to the outer periphery of the second arm, and one end is locked on the swing arm 20 side and the other end is locked on the fixed member side. Thus, the swing arm 20 may be constantly urged to swing in the above direction. The striated body supply device of this embodiment is configured as described above. When the striated body 1 is pulled out from the striated winding body 3 using this device and supplied to various facilities, devices, and the like, the striated body 1 is usually provided with an appropriate predetermined tension as shown in FIG. Stable supply. However, when the tension of the supplied filament 1 becomes larger than an appropriate predetermined tension, for example, due to a change in the amount of the filament 1 taken from the equipment, equipment, or the like, As shown in FIG. 3, when the swing arm 20 supplies the filament 1 against the urging by the urging member 23 (clockwise direction in FIG. 3) at a predetermined angle (when the amount of increase in the tension is large). (The rocking angle also increases)) and the tension acting on the brake cord 24 decreases. Then, the tightening of the brake drum 16 by the brake cord 24 becomes weaker, the amount of the filament 1 pulled out from the filament winding body 2 increases, and the tension of the supplied filament 1 decreases. And returns to the appropriate predetermined tension. On the other hand, when the tension of the supplied linear body 1 becomes smaller than an appropriate predetermined tension, the urging force of the urging member 23 of the swing arm 20 becomes smaller as shown in FIG. Is larger than the force for causing the swing arm 20 to swing in the direction in which the striated body 1 is supplied by the tension of the striated body 1, and the swing arm 20 has a direction opposite to that described above. That is,
4. Swing in the direction opposite to the direction in which the striated body 1 is supplied (counterclockwise in FIG. 4 in a direction that hinders the supply of the striated body 1) and swing a predetermined angle (if the amount of decrease in tension is large, swing (The angle also increases) and the tension acting on the brake cord 24 increases. Then, the tightening of the brake drum 16 by the brake cords 24 becomes strong, the amount of the filament 1 pulled out from the filament winding body 3 decreases, and the tension of the supplied filament 1 increases. And returns to the appropriate predetermined tension. Therefore, according to the umbilical member supply device of the present invention, the umbilical member 1 can be always supplied with a stable and appropriate predetermined tension. As described above, the linear body delivery device of the present invention comprises a linear body wound body formed by winding a linear body and supported rotatably, Guides and supplies the brake drum arranged on the side of the striated winding body so as to rotate integrally with the rotation of the striated winding body, and the striated body drawn out from the striated winding body A swing arm that swings in accordance with a change in the tension of the striated body drawn out and supplied from the striated winding body, and a tension acting on the slewing arm to the striated body. An urging member that constantly urges to swing in the direction in which it becomes larger, a brake string that is hung around the brake drum, one end of which is fixed, and the other end of which is attached to the swing arm; Therefore, according to the filament supply device of the present invention, the filament is always supplied with a stable and appropriate predetermined tension. Can be paid. Also, since the filament drawn out from the filament winding body is supplied through the guide portion of the swing arm, the outer surface of the filament comes into contact with the short and long wire rods and becomes rough. Also, fine trauma is not formed on the outer surface by rubbing with the guide portion, and a high-quality striatum can be supplied.
