Description

  The present invention relates to a cylindrical twisted yarn manufacturing apparatus that forms a cylindrical twisted yarn by twisting a tape-like material obtained by cutting paper or the like into thin pieces.

  The cylindrical twisted yarn formed by cutting paper into thin pieces and twisting it into a paper fabric by weaving it into a substitute for materials such as wallpaper, slippers, hats, seat covers, and tatami mats. It is used as a product.

  As a manufacturing apparatus for such a cylindrical twisted yarn, a holding means for rotatably holding a wound long tape-like article in a horizontal state, a tension adjusting means for adjusting a drawing tension of the tape-like article, and a tape-like article The twisting means including a pair of displacement rollers that are displaced in the axial direction so as to cause one end in the width direction to be twisted up to the other side in the width direction and to cause a winding phenomenon. The first frame is pivotally supported on the second frame so as to be rotatable about the conduction path direction of the tape-like object as the virtual center axis (see, for example, Patent Document 1). .

  According to this manufacturing apparatus, by adjusting the take-up speed of the tape-like material and the rotation speed of the first frame, various types of cylindrical twisted yarns having different diameters, number of layer walls, and cross-sectional states can be continuously formed. However, when the tape-like object that is running is twisted, the direction of the tape-like object that is running is twisted. Since the tension difference occurs in the width direction of the tape-like material and a force is applied to break the tape-like material, the material (paper) constituting the tape-like material has a high tensile strength or a relatively wide width. In addition, it was difficult to increase the production speed.

  Therefore, as a technique capable of solving such a problem, as shown in FIG. 5, a tape holder (3) for holding a supply winding body of the raw material tape (2) in the drawing direction of the tape arranged on one side of the base (1). Between the tape holder (3) and the take-up drum (4). The winding guide (4) is wound around the outer periphery of the string guide (5), and is arranged at the rear part of the string guide (5), and the feeding roll (6) for feeding out the tape (2) held in the tape holder (3). ) And a tension roll (7) that is arranged in the front part of the string guide (5) and adjusts the tension of the tape (2) drawn from the tape holder (3). The tape holder (3) is variable with respect to the drawing direction of the tape (2), the twist pitch and the number of twists are variable, and the string guide (5) is threaded by a cylindrical twisted thread. Tubular, or tubular twisting what was trough for guiding in the groove has been proposed.

According to such a manufacturing apparatus, the tape (2) pulled out from the tape holder (3) by the feed roll (6) can be twisted as it is, so that the production speed can be increased to some extent, and the tape holder ( Change the spiral pitch and number of twists of the tubular twisted yarn to some extent by changing the angle between the tape drawing direction in 3) and the number of rotations of the winding guide (4) and the string guide (5) that winds the outer periphery. be able to.

  However, the cylindrical twisted yarn production apparatus (8) shown in FIG. 5 has a problem that unwinding occurs unless the winding drum (4) is rotated at the same speed as the string guide (5).

  In addition, the string guide (5) winds the outer periphery of the winding drum (4) to apply a strong and fine twist to the cylindrical twisted yarn. At this time, the arm-shaped string guide (5) Because the centrifugal force acts, the rotational speed of the string guide (5) cannot be increased significantly, and although the spiral pitch and the number of twists can be changed to some extent, a twist with a large number of twists is applied at a fine pitch. There was a problem that it was difficult.

  Therefore, the main problem of the present invention is that the spiral pitch and the number of twists can be arbitrarily and greatly adjusted regardless of the tensile strength, width or thickness of the tape-like material, and the production speed can be increased. It is providing the cylindrical twisted-yarn manufacturing apparatus which can be improved.

  The invention described in claim 1 is the following: “The original fabric roll (W) formed by winding the tape-like material (P) is held so that the tape-like material (P) is drawn out in the drawing direction. The roll holding means (14), the tape-like object feeding mechanism (16) for feeding out the tape-like object (P) wound around the original fabric roll (W), and the rotating shaft (A) from the original fabric roll (W) A twist guide that is attached to be inclined with respect to the running direction of the tape-like object (P) that is fed, and that gives the tape-like object (P) a turn in which one end in the width direction is turned up to the other end side. The tape (P) is twisted by rotating the roller (18) and the tape-like material (P) fed with turning around the virtual axis (i) along the feeding direction in the turning direction. Tape twisting means (20) for forming into cylindrical twisted yarn (S), and cylindrical twisted yarn winding means (2) for sequentially winding the cylindrical twisted yarn (S) formed by the tape twisting means (20) 2), and the twist guide roller (18) is attached with a motor (40) that variably controls the inclination angle of the rotation axis (A) with respect to the traveling direction of the tape-like object (P), and the twist guide roller ( 18) and the tape twisting means (20) are installed so as to be close to and away from each other ”.

  In this invention, the original roll holding means (14) holds the original roll (W) so that the tape-like material (P) wound around the original roll (W) is drawn out in the drawing direction. Therefore, it is possible to prevent a tension difference from occurring in the width direction of the tape-like product (P) fed out from the original fabric roll (W) and applying a force that breaks the tape-like product (P).

  Here, in the conventional cylindrical twisted yarn manufacturing apparatus, when adjusting the turn-up state of the tape-like material, a method of adjusting the mounting angle of the twist guide roller by hitting the twist guide roller with a hammer or the like was adopted. In such a method, there is a problem that adjustment of the turned-up state of the tape-like material requires craftsmanship intuition and experience and poor reproducibility.

  However, in the tubular twisted yarn manufacturing apparatus (10) of the present invention, the twist guide roller (18) has a motor (40) that variably controls the inclination angle of the rotating shaft (A) with respect to the traveling direction of the tape-shaped object (P). Since it is attached, even during the operation of the cylindrical twisted yarn manufacturing apparatus (10), the inclination angle of the rotating shaft (A) can be arbitrarily and easily changed by variably controlling the motor (40). be able to. Therefore, a desired turn can be imparted to the tape-like material (P) regardless of the width, thickness, strength, running speed, etc. of the tape-like material (P).

  In addition, when the width, thickness, strength, running speed, etc. of the tape-like material (P) are different, the position where the turning applied by the twist guide roller (18) is stable also changes, but the twist guide roller ( 18) and the tape twisting means (20) are installed so as to be close to and away from each other, so even if the state of the tape-like material (P) is different as described above, the twist guide roller (18) and the tape twisting By adjusting the distance (T) from the means (20), it is always possible to add a predetermined twist to the tape-like material (P) after the turn applied by the twist guide roller (18) is stabilized. .

  In addition, since the twist guide roller (18) and the tape twisting means (20) are independent and independent, the inclination angle of the rotating shaft of the twist guide roller (18) and the rotation speed of the tape twisting means (20) are determined. Each can be adjusted individually, and cylindrical spiral yarns (S) having various spiral pitches and twist numbers can be obtained.

  The invention described in claim 2 is the cylindrical twisted yarn manufacturing apparatus (10) according to claim 1, wherein "the twist guide roller (18) in the travel path of the tape-like object (P) On the upstream side, a slack removing roller device (42) for removing slack of the tape-like material (P) when the tape-like material (P) contacts the twist guide roller (18) is attached. '' As a result, the tape-like material (P) in contact with the twist guide roller (18) meanders and the turning is unstable (that is, the spiral pitch of the cylindrical twisted yarn (S) is not uniform). Can be prevented.

  The invention described in claim 3 is the cylindrical twisted yarn manufacturing apparatus (10) according to claim 1 or 2, wherein "tape-like material feeding mechanism (16) is tape-like ( A dancer roller (26) around which a tape-like material (P) is wound, and a roll roll holding means provided between the twist guide roller (18) and the roll roll holding means (14) in the traveling path of (P). A servo motor (24) attached to the shaft (14a) that pivotally supports the roll (W) of (14) and for controlling the amount of feeding of the tape-like material (P) based on the position signal of the dancer roller (26) (24 ) And "".

  In the present invention, the number of revolutions of the raw roll (W), that is, the feeding amount of the tape-like material (P) can be adjusted with high accuracy by the servo motor (24), so that it is based on the position signal of the dancer roller (26). Thus, the tension of the tape-like material (P) fed out from the original fabric roll (W) can be accurately controlled so as to be within a predetermined range.

  In addition, the dancer roller (26) is displaced so that the tension of the wound tape-like object (P) falls within a certain range. For some reason, excessive tension is applied to the tape-like object (P). Even if it is applied, it is possible to prevent the dancer roller (26) from moving in a direction that relaxes the tension applied to the tape-like object (P) and breaking the tape-like object (P).

  The invention described in claim 4 is the cylindrical twisted yarn manufacturing apparatus (10) according to claim 3, in which the dancer roller (26) and the twist guide in the traveling path of the tape-shaped object (P) are provided. Between the roller (18), a plurality of feed rollers (30a) that are in rolling contact with the tape-like object (P) are arranged displaced in the vertical and front-rear directions, and the tape-like object (P) is twisted into the guide roller (18). And a tape-like material feeding device (30) that feeds at a constant speed toward the cylindrical twisted yarn winding means (22) between the twist guide roller (18) and the tape-like material feeding device (30).

Become. Therefore, when the tape-like object (P) fed out from the original roll (W) passes through the feed roller (30a), the feed roller (30a) is idled to disturb the feeding operation of the tape-like object (P). Can be prevented. In addition, by providing such a tape-like object feeding device (30), free run of the tape-like object (P) between the dancer roller (26) and the twisting guide roller (18), i.e., still twisting. It is not provided, and the distance traveled by the tape-like material (P) having a lower tensile strength than the cylindrical twisted yarn (S) without any support can be shortened. For this reason, even a tape-like product (P) having a low tensile strength or a narrow width can be formed into a cylindrical twisted yarn (S) without cutting the tape-like product (P).

  Further, the cylindrical twisted-winding means (22) is wound on the cylindrical twisted-winding means (22) so that the tension of the tape-like material (P) detected by the tension detecting device (32) is constant. By attaching the brake means (22a) that adjusts the tension, the tape-like object (P) can be sent toward the twist guide roller (18) at a constant speed and tension, and the tape-like object (P) is twisted.

An air cylinder (26a) that adjusts the displacement load of the dancer roller (26) is attached so that the tension of the tape-like object (P) detected by the tension detector (32) attached between It is characterized by being "

  In this invention, when the cylindrical twisted yarn (S) passes through the drawing roller (52a), it passes through the zigzag path, so that the effective length of rolling contact between the cylindrical twisted yarn (S) and the drawn roller (52a) is long. Become. Therefore, when the cylindrical twisted yarn (S) drawn from the tape twisting means (20) passes through the drawing roller (52a), the drawing roller (52a) is idled and the feeding operation of the cylindrical twisted yarn (S) is disturbed. The cylindrical twisted yarn (S) is hardly affected by the winding operation of the cylindrical twisted yarn winding means (22), and the drawing operation of the cylindrical twisted yarn (S) is stably performed. It becomes like this.

  In addition, when the width, thickness, strength or running speed of the tape-like material is different, the position where the turn applied by the twist guide roller is stable also changes, but the twist guide roller and the tape twisting means are close to each other. Since it is installed so that it can be separated, a predetermined twist can be applied to the tape-like material after the turning applied by the twist guide roller is always stabilized.

  Furthermore, since the inclination angle of the rotating shaft of the twist guide roller and the rotation number of the tape twisting unit can be individually adjusted, cylindrical twisted yarns having various spiral pitches and twist numbers can be obtained.

  Hereinafter, the cylindrical twisted-yarn manufacturing apparatus of this invention is explained in full detail according to drawing. FIG. 1 is a block diagram showing a cylindrical twisted yarn manufacturing apparatus (10) according to an embodiment of the present invention, and FIG. 2 is a schematic view showing a main part of the cylindrical twisted yarn manufacturing apparatus (10) according to the present embodiment. is there.

  The cylindrical twisted yarn manufacturing apparatus (10) of the present invention is an apparatus for drawing a tape-shaped article (P) made of paper or the like wound around a raw fabric roll (W) to form a cylindrical twisted yarn (S), As shown in FIGS. 1 and 2, the apparatus main body (12), the fabric roll holding means (14), the tape-like material feeding mechanism (16), the twist guide roller (18), the tape twisting means (20), and the cylinder It is composed of a twisted yarn winding means (22) and the like.

  As shown in FIG. 1, the apparatus main body (12) is installed on a base (12a), a plurality of struts (12b) erected on the base (12a), and an upper portion of the strut (12b). Consists of an upper wall (12c), an upper column (12d) erected on the upper wall (12c), and an arm (12e) extending horizontally from the side of the upper column (12b) Has been.

  The material roll holding means (14) supports the cylindrical shaft (R) of the material roll (W) formed by winding the tape-shaped material (P), and the tape-shaped material (P) is in the unwinding direction. The roll (W) is held so that it can be fed out, and is rotatably attached to the arm (12e), and a shaft (14a) that pivotally supports the cylindrical shaft (R) of the roll (W) Have. Then, a constant tension is applied to the shaft (14a) with respect to the tape-like material (P) wound around the original roll (W) (while adjusting the back tension), and the rewinding is completed from the beginning. The tape-like object (P) can be fed out in a constant state until a servo motor (24) constituting a tape-like object feeding mechanism (16) described later is attached.

  The tape-like material feeding mechanism (16) is for feeding the tape-like material (P) wound around the raw fabric roll (W), and is a dancer roller (attached to the column (12b) so that it can be displaced vertically. 26) and the servo motor (24) described above.

  The position of the dancer roller (26) is displaced according to the tension of the wound tape-like object (P) (in this embodiment, it moves up and down) to adjust the tension applied to the tape-like object (P). It is a rotating body.

  A sensor (28) for detecting the vertical position of the dancer roller (26) is attached to the dancer roller (26), and the rotation speed of the servo motor (24) is controlled based on the position signal detected by the sensor (28). It is like that. Specifically, when the position of the dancer roller (26) exceeds the preset upper limit position, the rotation speed of the servo motor (24) increases to increase the feeding amount of the tape-like object (P), and the tape-like object The tension applied to (P) is reduced. On the other hand, when the position of the dancer roller (26) falls below the preset lower limit position, the rotation speed of the servo motor (24) decreases and the feeding amount of the tape-like object (P) is reduced, and the tape-like object (P ) Will be tensioned.

  The dancer roller (26) is provided with an air cylinder (26a) for adjusting a load (i.e., a displacement load) when the dancer roller (26) is displaced, and a cylindrical twisted yarn drawing device (52 described later) When using the tension detection device (32), the tension of the tape (P) detected by the tension detection device (32) provided at the upper end of the upper column (12d) is constant. The cylinder pressure of the air cylinder (26a) is adjusted based on the detection signal, and the displacement load of the dancer roller (26) is adjusted.

  Here, in the cylindrical twisted yarn manufacturing apparatus (10) of the present embodiment, on the upper wall (12c) of the apparatus main body (12), a plurality of feed rollers (30a) and a guide that are in rolling contact with the tape-shaped object (P). A tape (30b), and a tape-like material feeding device (30) for feeding the tape-like material (P) toward the guide roller (18) at a constant speed is attached. In the tape-like article feeding device (30), a plurality (two in this embodiment) of feeding rollers (30a) are arranged so as to be displaced in the vertical and front-rear directions.

  Further, at the upper end of the upper column (12d), the meandering correction roller (34) that senses the position of the tape-like object (P) that has passed through the tension detection device (32) and corrects the meandering of the tape-like object (P). ) Is attached. The meandering correction roller (34) automatically adjusts the inclination angle of the tape-like object (P) with respect to the running direction based on the sensed travel position of the tape-like object (P), so that the tape-like object (P) is constant. The correction is made so that the vehicle travels along the route.

  The twist guide roller (18) is attached so that the rotation axis (A) is inclined with respect to the running direction of the tape-like object (P) (see FIG. 2), and the width direction of the tape-like object (P) is It turns over so that one end is turned up to the other end.

  This twist guide roller (18) is attached to a plate-like support member (38) that moves up and down along a guide member (36) suspended from the upper part of the upper column (12d) (that is, a twist guide). The roller (18) and the tape twisting means (20) can be moved close to each other), and the rotation axis (A) with respect to the running direction of the tape-like object (P) by the motor (40) fixed to the support member (38) The tilt angle is variably controlled (servo motor control) (see FIG. 2).

  Further, the tape-like object (P) at the position where the twist guide roller (18) is attached in the support member (38) is mounted on the upstream side of the travel path, and the slack eliminating roller device (42) is attached. The slack of the tape-like material (P) when it comes into contact with the twist guide roller (18) is removed.

  As shown in FIG. 3, the slack eliminating roller device (42) freely supports the rotational movement of the roller frame (42a) and its inner ring (42b) in the horizontal direction (that is, in the roller frame (42a)). Rotating direction follower bearing (42b), both ends of the inner ring (42b) of the rotating direction follower bearing (42b) are pivotally supported, and a rotating roll (42c) that rotates around the axis of the shaft (42c a), horizontal direction The shaft (42e), the roller frame (42a), and the shaft (42e), which are attached to the support member (38) via the slide bearing (42d) that freely supports the forward and backward movement at the shaft (42e) The tilting follower support shaft (42f) that swingably supports the roller frame (42a) in the axial direction of the shaft, and the back interposed between the tilting follower support shaft (42f) and the pressure adjusting knob (42g). It consists of a tension spring (42h). For this reason, as shown in FIG. 2, in the slack eliminating roller device (42), the inclination angle of the rotating roll (42c) with respect to the running direction and the width direction of the tape-like object (P) is passively and freely adjusted. (I.e., the gyro mechanism is configured) and the tension of the back tension spring (42h) is adjusted by advancing and retracting the pressure adjustment knob (42g), and the rotating roll (42c) is turned into a tape-like object (P). The tension to be applied can be adjusted. As a result, the rolling contact area and the tension when the tape-like material (P) rolls on the rotating roll (42c) can always be kept constant, and the tape-like material (P) is the twist guide roller (18) described above. It is possible to completely remove the slack of the tape-like material (P) when it comes into contact with the tape.

  Further, on the downstream side of the travel path of the tape-like material (P) at the position where the twist guide roller (18) is attached in the support member (38), a turn that passes through the twist guide roller (18) and becomes a trigger for twist is given. A twist guide (44) for guiding the traveling of the tape (P) is attached.

  The tape twisting means (20) adds the tape-like material (P) by rotating the tape-like material (P) fed while being turned around the virtual axis (i) along the running direction in the turning direction. Twist to form a cylindrical twisted yarn (S) (see Fig. 2), a rotation motor (46) attached to the support column (12b), and a plurality of (three in this example) rollers inside (48), and a cylindrical rotating frame (50) to which the rotational force of the motor for rotation (46) is applied via the belt (B).

  Here, in the cylindrical twisted yarn manufacturing apparatus (10) of the present embodiment, as shown in FIG. 2, on the virtual axis (i) along the feed path of the tape-like object (P) extending in the vertical direction, from above, The rotating frame (50) of the meander correction roller (34), the slack eliminating roller device (42), the twist guide roller (18), the twist guide guide (44) and the tape twist means (20) are arranged in this order, In addition, the inclination angle of the twist guide roller (18) and the rotational speed of the tape twist means (20) can be controlled in conjunction with each other.

  Further, in this embodiment, a plurality of drawing rollers (52a) and guide rollers (52b) that are in rolling contact with the cylindrical twisted yarn (S) are provided immediately below the rotating frame (50), and the cylindrical twisted yarn (S) is provided. A cylindrical twisting-out device (52) for pulling out from the tape twisting means (20) at a constant speed is attached. In this cylindrical twisted yarn drawing device (52), a plurality (two in this embodiment) of drawing rollers (52a) are arranged so as to be displaced in the vertical and front-rear directions.

  The cylindrical twisted-winding means (22) is an apparatus for sequentially winding the cylindrical twisted yarn (S) formed by the tape twisting means (20) .In this embodiment, the winding thread (54) and this winding This is a traverse device composed of a flyer ring (56) that turns around the outer periphery of the drum (54).

  The cylindrical twisted yarn winding means (22) is provided with a brake means (22a) for adjusting the winding tension of the cylindrical twisted yarn winding means (22). In the case of the present embodiment, this corresponds to a powder brake for adjusting the rotational load of the flyer ring (56). This brake means (22), when using the tape-like material feeding device (30) described above, tape-like material (32) that is detected by a tension detection device (32) provided at the upper end of the upper column (12d) ( This is for adjusting the winding tension of the tubular twisted yarn winding means (22) by adjusting the rotational load of the flyer ring (56) so that the tension of P) is constant.

  In the cylindrical twisted yarn manufacturing apparatus (10) configured as described above, the control of each component, for example, the rotation speed of the servo motor (24), the inclination angle of the twist guide roller (18), the tape twisting means (20) Control of the rotational speed and the winding speed of the cylindrical twisted winding means (22) can be collectively managed by the control means (58). Therefore, in advance, the twist angle of the twist guide roller (18) in various tapes (P) with different tensile strength, width, etc., the rotational speed and production speed of the tape twisting means (20), and the obtained cylindrical twisted yarn (S) The desired cylindrical twisted yarn (S) can be obtained with good reproducibility by obtaining data on the relationship between the two and inputting an instruction to the control means (58) based on the data.

  When manufacturing the cylindrical twisted yarn (S) using the cylindrical twisted yarn manufacturing apparatus (10) of the present embodiment, the original fabric roll (W) is set in the original fabric roll holding means (14), and the original fabric roll Pull out the tip of the tape (P) from (W). Then, the tape-like object (P) is set in a predetermined feeding path, and the tip thereof is engaged with the winding drum (54) of the cylindrical twisted-winding means (22). In the case of the embodiment shown in FIG. 1, only the tape-like material feeding device (30) is used as means for adjusting the tension of the tape-like material (P) traveling through the cylindrical twisted yarn manufacturing device (10). The cylindrical twist drawing device (52) is not used (the cylindrical twisted yarn (S) wound around the guide roller (52b) is directly applied to the cylindrical twisted yarn winding means (22)).

  Subsequently, the power of the cylindrical twisted yarn manufacturing apparatus (10) is turned on, and the servo motor (24), the tape-shaped article feeding device (30), the rotating motor (46) and the cylindrical twisted yarn winding means (22) are turned on. Operate. Then, the tape-like material (P) is fed out from the original roll (W), and this tape-like material (P) is a dancer roller (26), a tape-like material feeding device (30), a meandering correction roller (34), and a slack. The twisted guide roller (18) is fed through a take-up roller device (42).

  According to the cylindrical twisted yarn manufacturing apparatus (10) of the present embodiment, the raw roll holding means (14) allows the tape-like article (P) wound around the raw roll (W) to be drawn out in the drawing direction. Since the fabric roll (W) is held on the tape, the difference in tension occurs in the width direction of the tape-like material (P) fed out from the fabric roll (W) so that the tape-like material (P) is broken. Can be prevented from applying excessive force.

  Here, in the conventional cylindrical twisted yarn manufacturing apparatus, when adjusting the turn-up state of the tape-like material, a method of adjusting the mounting angle of the twist guide roller by hitting the twist guide roller with a hammer or the like was adopted. In the cylindrical twisted yarn manufacturing apparatus (10) of the present invention, a motor (40) that variably controls the inclination angle of the rotation shaft (A) with respect to the traveling direction of the tape-like object (P) is attached to the twist guide roller (18). Therefore, even during the operation of the cylindrical twisted yarn production apparatus (10), the tilt angle of the rotating shaft (A) can be arbitrarily and easily changed by variably controlling the motor (40). it can. Therefore, a desired turn can be imparted to the tape-like material (P) regardless of the width, thickness, strength, running speed, etc. of the tape-like material (P).

  In addition, when the width, thickness, strength, running speed, etc. of the tape-like material (P) are different, the position where the turning applied by the twist guide roller (18) is stable also changes, but the twist guide roller ( 18) and the tape twisting means (20) are installed so as to be close to and away from each other, so even if the state of the tape-like material (P) is different as described above, the twist guide roller (18) and the tape twisting By adjusting the distance (T) from the means (20), it is always possible to add a predetermined twist to the tape-like material (P) after the turn applied by the twist guide roller (18) is stabilized. .

  In addition, since the twist guide roller (18) and the tape twist means (20) are independent and independent, the inclination angle of the rotation shaft (A) of the twist guide roller (18) and the tape twist means (20) The number of rotations can be adjusted individually, and cylindrical twisted yarns (S) with various spiral pitches and twists can be obtained.

  Further, on the upstream side of the twist guide roller (18) in the travel path of the tape-like object (P), the tape-like object (P) when the tape-like object (P) abuts on the twist guide roller (18) Since the slack eliminating roller device (42) for removing the slack is attached, it is possible to prevent the tape-like object (P) that comes into contact with the twist guide roller (18) from meandering and causing the turning to become unstable.

  Further, a tape-like object feeding mechanism (16) is provided between the twist guide roller (18) and the raw roll holding means (14) in the travel path of the tape-like object (P), and the tape-like object (P) Is mounted on the dancer roller (26) around which the belt is wound and the shaft (14a) that pivotally supports the original roll (W) of the original roll holding means (14), and the tape is based on the position signal of the dancer roller (26). Servo motor (24) that controls the amount of feed (P) feed, and the servo motor (24) controls the rotation speed of the roll (W), that is, the feed amount of the tape (P). Since it can be adjusted with high accuracy, the tension of the tape-like material (P) fed out from the original roll (W) is controlled accurately based on the position signal of the dancer roller (26) within the specified range. can do.

  Furthermore, since the position of the dancer roller (26) is displaced so that the tension of the wound tape-like object (P) falls within a certain range, excessive tension is applied to the tape-like object (P) for some reason. Even if it is applied, it is possible to prevent the dancer roller (26) from moving in a direction that relaxes the tension applied to the tape-like object (P) and breaking the tape-like object (P).

  And, in the tape-like material feeding device (30) provided between the dancer roller (26) and the twist guide roller (18), when the tape-like material (P) passes the feeding roller (30a), the zigzag shape Therefore, the effective length of rolling contact between the tape-like object (P) and the feed roller (30a) becomes longer. Therefore, when the tape-like object (P) fed out from the original roll (W) passes through the feed roller (30a), the feed roller (30a) is idled to disturb the feeding operation of the tape-like object (P). Can be prevented. In addition, by providing such a tape-like object feeding device (30), free run of the tape-like object (P) between the dancer roller (26) and the twisting guide roller (18), i.e., still twisting. It is not provided, and the distance traveled by the tape-like material (P) having a lower tensile strength than the cylindrical twisted yarn (S) without any support can be shortened. For this reason, even a tape-like product (P) having a low tensile strength or a narrow width can be formed into a cylindrical twisted yarn (S) without cutting the tape-like product (P).

  Further, the cylindrical twisted-winding means (22) is wound on the cylindrical twisted-winding means (22) so that the tension of the tape-like material (P) detected by the tension detecting device (32) is constant. Since the brake means (22a) for adjusting the tension is attached, if this brake means (22a) is used in combination with the tape-like object feeding device (30), the tape-like object (P) is twisted at a constant speed and tension. The tape can be fed toward the guide roller (18), and the twisting operation of the tape-like object (P) can be executed more stably.

  In the above-described embodiment, the case where the tape-shaped article feeding device (30) is used as means for adjusting the tension of the tape-shaped article (P) traveling through the cylindrical twisted yarn manufacturing apparatus (10) is shown. When the tensile strength of the tape-like material (P) is high, as shown in FIG. 4, it is possible to use only the cylindrical twist puller (52) instead of the tape-like material feeding device (30). Good.

  In this case, since the cylindrical twisted yarn (S) passes through the zigzag path when passing through the drawing roller (52a), the effective length of rolling contact between the cylindrical twisted yarn (S) and the drawing roller (52a) is long. Become. Therefore, when the cylindrical twisted yarn (S) drawn from the tape twisting means (20) passes through the drawing roller (52a), the drawing roller (52a) is idled and the feeding operation of the cylindrical twisted yarn (S) is disturbed. The cylindrical twisted yarn (S) is hardly affected by the winding operation of the cylindrical twisted yarn winding means (22), and the drawing operation of the cylindrical twisted yarn (S) is stably performed. It becomes like this. In addition, the air cylinder (26a) for adjusting the displacement load of the dancer roller (26) so that the tension of the tape-like object (P) detected by the tension detector (32) is constant on the dancer roller (26). Therefore, if this air cylinder (26a) is used in combination with the cylindrical twisted-pull-out device (52), the tape (P) can be pulled into the twisting guide roller (18) at a constant speed and tension. Thus, the twisting operation of the tape-like product (P) can be executed more stably.

  Further, in the above-described example, the tape-like material feeding device (30) or the cylindrical yarn drawing-out device (52) is used as means for assisting the traveling of the tape-like material (P) on the cylindrical twisted yarn manufacturing device (10). Although the case where it is used alone has been shown, both the tape-like article feeding device (30) and the cylindrical twisted yarn drawing device (52) may be used in combination. However, in this case, the cylinder pressure of the air cylinder (26a) and the braking of the brake means (22a) are not controlled based on the tension of the tape-like object (P) detected by the tension detector (32). However, it is necessary to control the feeding speed of the tape-like article (P) in the tape-like article feeding device (30) or the withdrawal speed of the cylindrical twisting yarn (S) in the cylindrical twisting-out device (52) based on the tension. is there.

  In addition, in the cylindrical twisted yarn manufacturing apparatus (10) shown in FIGS. 1 and 4, the case where both the tape-shaped material feeding device (30) and the cylindrical twisted yarn drawing device (52) are provided is shown. Only one of them may be provided.
