Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn supplying device for supplying a weft of a weaving machine and supplying an original yarn to a twining device or a twisting machine. The present invention relates to a ballooning control unit of a yarn supplying device that pulls out a yarn in an axial direction and a yarn supplying device provided with such a ballooning control unit.

[0002]

2. Description of the Related Art Generally, a weft of a loom is supplied by drawing a yarn in an axial direction from a yarn supplying body in which the yarn is wound in a cylindrical or conical shape. In this case, since the yarn is drawn while circling the cylindrical or conical surface of the yarn feeder, a centrifugal force accompanying the wrapping of the yarn acts on the yarn immediately after being pulled out, and the unwound yarn becomes the yarn of the yarn feeder. The so-called ballooning that bulges outward from the outer periphery occurs. Due to this ballooning, the yarn is unwound so as to be drawn radially outward from the peripheral surface of the yarn supplying body. Therefore, the yarn is unwound with relatively stable tension without rubbing against the adjacent yarn on the peripheral surface of the yarn supplying body. Is performed. However, in order to utilize such features effectively, it is essential that a stable balloon is formed in the entire area of the yarn withdrawal.

[0003] Factors that hinder the formation of a stable balloon include an increase in the yarn pulling speed and a change in the diameter of the yarn supplying body due to the unwinding of the yarn. When the yarn withdrawing speed increases, the winding speed of the unwound yarn rapidly decreases due to an increase in air resistance that suppresses the turning of the yarn, and the yarn is drawn while drawing a spiral. When this state is observed from the side of the yarn feeder, it appears that the yarn is pulled out from the yarn feeder while waving. Also, even if the drawing speed is the same, if the diameter of the yarn supplying body decreases along with the yarn feeding, more circling operations are required to pull out a yarn of the same length, and the yarn drawing speed is increased. A phenomenon similar to the case described above occurs.

When the unwound yarn is drawn out in a spiral and wavy, the yarn is drawn out while lying in the axial direction of the yarn feeder at the unwinding point. The yarn is unwound while rubbing the adjacent yarn, the unwinding resistance increases, and the tension of the yarn fluctuates, and the yarn for a plurality of windings at the yarn drawing-out end of the yarn feeder is removed from the yarn feeder. The so-called loop-through phenomenon of detachment occurs, and the tension of the yarn changes suddenly,
Thread breakage may occur due to entanglement of the thread.

[0005] The yarn unwound from the yarn feeder causes ballooning between the yarn guide and a yarn guide placed on the axis of the yarn feeder (on the yarn pull-out shaft) at a predetermined interval from the yarn feeder. The shape of the balloon is greatly affected by the distance between the yarn feeder and this yarn guide, and when the unwound yarn is drawn out in a spiral and wavy as described above, the yarn guide is brought closer to the yarn feeder. Thus, such an unstable release state can be eliminated, and the unwinding tension also decreases. For example, when one end of a long skipping rope is fixed and the other end is turned quickly, when the string is long, the entire string can not be turned,
It is the same principle that the entire string can be turned faster if the string is shortened.

To solve this problem, Japanese Patent Application Laid-Open No. 63-126945 discloses that a ballooning state is detected by a line sensor and the distance between the yarn supplying body and the yarn guide is automatically adjusted according to the detected value. Yarn feeders have been proposed.
However, such a device requires an expensive line sensor for detecting the shape of the balloon, a servomotor for moving the yarn guide, and a control device therefor, which makes the device very expensive. Also, as is apparent from the above-described phenomenon, as the yarn is unwound from the yarn feeder and the diameter of the yarn feeder decreases, it is necessary to move the yarn guide in a direction to approach the yarn feeder.
When all the yarns of one yarn feeder are unwound and moved to the next yarn feeder, it is impossible to instantaneously return the yarn guide to a position away from the yarn feeder. There is a problem that the yarn tension is greatly fluctuated at the time of conversion and yarn breakage easily occurs.

In order to supply a substantially infinite length of yarn from the yarn supplying body, a plurality of yarn supplying members are loaded into a holder, and the end of the yarn of the yarn supplying yarn that is unwound first and then unwound. The end of the yarn of the supply body to be connected is connected. After the yarn of the previous yarn supply is unwound, a new yarn supply is loaded into the holder until all the yarns of the yarn supply loaded in the holder are unwound, and the already loaded yarn is already loaded. By connecting the end of the yarn of the supplied yarn feeder to the leading end of the yarn of the newly loaded yarn feeder, it is possible to continue supplying a yarn of substantially infinite length. A plurality of yarn feeders have a constant distance from the yarn guide, and an axis (an axis in a direction in which the yarn is unwound; usually, a center axis of a cylindrically wound yarn feeder) is directed toward the yarn guide. It is loaded in the holder in a state of being juxtaposed.
Therefore, when moving from one yarn feeder to the next yarn feeder, the direction in which the yarn enters the yarn guide from the yarn feeder changes. By detecting the change in the entering direction of the yarn, it is possible to detect that the unwinding of the yarn has moved from one yarn supplying body to the next yarn supplying body.

[0008] In such a yarn feeder in which the yarn ends of a plurality of yarn feeders mounted side by side are connected to each other to supply a yarn of substantially infinite length, the yarn is supplied by unwinding the yarn. As the diameter of the thread decreases, it is not possible to make the distance between the thread guide and the thread feeder closer. This is because the yarn guide must be arranged at a position where the axes of the plurality of yarn feeders intersect, and when the yarn guide approaches the yarn feeder as the yarn of one yarn feeder is unwound, This is because when the unwinding moves to the next yarn feeder, the yarn guide from the next yarn feeder cannot be unwound unless the yarn guide is momentarily returned to the normal position.

[0009]

The present invention can be applied to a yarn supplying device for supplying a substantially infinite length of yarn by connecting the yarn ends of a plurality of yarn supplying members. It is an object of the present invention to provide a yarn feeder which does not cause various problems caused by a change in ballooning form caused by the problem, for example, a problem such as a missing thread of a yarn from a yarn feeder and a change in tension of a supplied yarn. Also, the present invention relates to the invention of the inventors of the present application of Japanese Patent Application No. 9-1.
The present invention relates to an improvement of the invention described in Japanese Patent No. 87674, and more precisely controls ballooning caused by a change in the diameter of a yarn supplying body, thereby enabling yarn to be supplied with more stable tension. That is the task.

[0010]

A ballooning control guide of a yarn feeding device according to the present invention includes a main rod 10, a plurality of branch rods 11 extending radially from the main rod, and a thread inserted through the tip of each branch rod. And rings 3 and 4. The plurality of rings have a central axis 7 which is parallel or intersects with the main rod at the same point, and each ring is connected to the branch rod 11 from one side of the branch rod to the inside of the ring with respect to the circumference of the ring. And a through slit 13 that is connected substantially obliquely and without a step. The oblique direction of the plurality of rings is the same for all the rings, and the main rod 10 is mounted so that the ring 3 is on the axis of the yarn feeder and intermittently rotates with respect to the yarn feeder.

When a plurality of rings provided one for each of the plurality of branch rods have different diameters, the plurality of rings are arranged at the same or different positions in the axial direction of the main rod. Preferably, a small diameter thing is arrange | positioned near a yarn feeder.
When the diameters of the plurality of rings are the same, the plurality of rings are arranged at different positions in the axial direction of the main rod.

According to a third aspect of the present invention, in the ballooning control guide provided with the above means, the main rod and the branch rod are formed of a metal wire. The ring is formed integrally with the branch by bending a metal wire extending from the tip of each branch into a circular shape. The through slit 13 is formed between the distal end 3a of the metal wire formed on the ring and the bent portion 3b of the wire at the distal end of the branch rod.

A ballooning control device for a yarn supplying device according to a fourth aspect of the present invention is a ballooning control guide having the above-described structure in which a plurality of rings sequentially moving forward and backward on a yarn drawing shaft of a yarn supplying body are arranged at an equal angle around a main rod. And its ring driving means 16
And the through slit 13 of each ring is located on the rear side in the retreating movement direction when the ring which has entered first by the reciprocation driving means 16 of the ring retreats from the thread pull-out shaft 7. .

According to a fifth aspect of the present invention, there is provided a yarn feeding device comprising:
And a yarn feeder holder 19 for holding a plurality of yarn feeders 1 mounted with their axes aligned with the plurality of yarn pull-out shafts 7 passing through the yarn guide, and the plurality of rings 3 around the main rod 10. Ballooning control guide 5 of the above structure arranged at an equal angle
A rotation shaft 15 for intermittently rotating the ballooning control guide 5 at an angle equal to the equal angle, and a driving device 16 for driving the yarn supply body holder 19. The thread 1 is arranged at equal intervals on the same circumference around the pivot 6 in the thread supply holder 19, and the ballooning control guide 5 aligns the main rod 10 with the pivot 6, and turns the base end by the rotation. It is provided fixed to the driving shaft 15. The turning shaft 6 is an axis passing through the yarn guide 9 at the center of the plurality of yarn pulling shafts 7.

[0015]

The ring 3 which has advanced between the yarn supplying body 1 and the yarn guide 9 guides the unwound yarn which is about to spread outward by centrifugal force on the inner periphery. At a predetermined timing during which the yarn is unwound and the diameter of the yarn supplying body 1 changes, the ring is converted. The conversion of the ring is performed by retracting the previously selected ring from between the yarn guide 9 and the yarn supplying body 1 and causing the newly selected ring to advance between the yarn guide 9 and the yarn supplying body 1. Do. The yarn bends from the through slit of the previous ring to the outside of the ring in cooperation with the centrifugal force acting on the yarn due to the bending of the yarn accompanying the retreating operation of the previous ring. On the other hand, due to the circling operation of the yarn by ballooning, the yarn that has escaped from the previous ring collides with one side of the branch of the newly entered ring, and is pulled toward the tip end of the branch with the circling of the yarn, Further, it is guided to the inside of the ring through the through slit. The number of rings to be used during the time from the start of unwinding to the end of unwinding of the yarn feeder, the number of rings used between the yarn feeder and the yarn guide, depending on the diameter of the yarn feeder, the yarn drawing speed, and the like. By selecting the position, the diameter of each ring, and the timing at which the rings are converted, ballooning can be controlled to an optimum state and yarn supply with stable tension can be realized.

When switching the yarn feeder by connecting the yarn ends of a plurality of yarn feeders loaded in the yarn feeder holder, utilizing the fact that the drawing direction of the yarn (picktail yarn) of the connected portion changes. The ring can be converted without causing the ring to move forward and backward. For this purpose, the pick tail yarn may be extended in the direction passing through the through slit of the previous ring, and the ring selected next may wait on the yarn drawing axis of the next yarn supplying body. In this case, the first ring is a ring corresponding to the small diameter side of the yarn supplying body, and the new ring is a ring corresponding to the large diameter side of the yarn supplying body. That is, the conversion of the yarn between the rings having different distances from the yarn supplying body is instantaneously performed simultaneously with the conversion of the yarn supplying body.

In the yarn supplying device to which the present invention is applied, one or more yarn supplying members may be loaded in the yarn supplying member holder. The number of yarns and the number of rings when a plurality of yarns are loaded need not be the same, and the number of yarns may be determined in consideration of the efficiency of the work required for loading the yarns, and The number of rings should be determined according to the size of the yarn supplying body and the yarn supplying conditions as described above.

[0018]

1 to 3 show a first embodiment of the present invention.
This is an example of an embodiment provided with a yarn supply holder 19 capable of loading two yarn supply members 1 and a ballooning control guide 5 having two rings 3A and 3B. In FIGS. 1 and 2, a yarn supply body holder 19 holds yarn supply bodies 1 </ b> A and 1 </ b> B at symmetrical positions on both sides of the rotating shaft 6. Yarn supply 1
A, 1B central axes (yarn pull-out axes) 7, 7 intersect on a pivot 6 and a yarn guide 9 is provided at the intersection.

The ballooning control guide 5 includes a branch rod 11A extending from the middle of the main rod 10 to the opposite side.
11B, and a ring 3A, 3B at the tip of each branch rod.
Are formed. The main rod 10, the distal branch rod 11A and the distal ring 3A are formed integrally by bending a single wire. The intermediate branch rod 11B and the intermediate ring 3B are formed integrally by bending another wire rod, and
The base end of 1B is welded to an intermediate position of the main rod 10. As shown in FIG. 2, the rings 3A and 3B bend the tip of each branch rod approximately 90 degrees, and then bend so as to draw a circle in the same direction as the ballooning turning direction of the yarn pulled out from the yarn supplying body 1. It is formed by this. A gap 13 through which the thread can pass is formed between the tip of the ring-shaped wire and the bent portion between the branch rod and the ring. This gap 13 is a through slit described in the claims. The gap 13 is formed by a bent metal wire at a portion extending from one side of the branch rod to the inside of the ring, and thus forms a through slit that is substantially oblique to the circumference of the ring 3.

In the example of the drawing, how the through slit 13 is formed, the curvature of the bent portion between the branch rod 11 and the ring 3, the positional relationship between the bent portion and the tip 3a of the ring, and the ring The cutting angle at the end of the yarn is an important point for smoothly operating the yarn feeding device of the present invention. In the present invention, the ring 3 guides the unwound yarn from the yarn supplying body 1 which is about to be spread outward by ballooning on the inner periphery thereof. The guided yarn 14 orbits around the inner circumference of the ring from the base end (bent portion) 3b side to the tip end side. When the yarn moves from the distal end to the proximal end, it crosses the slit 13. At this time, a centrifugal force and a circumferential inertia force are acting on the yarn.
The thread is formed by the through slit 13 due to centrifugal force.
Through the through slit 13 due to inertial force during this time. For example, if the bent portion 3b is sharply bent to widen the gap between the tip 3a of the ring and the bent portion 3b, the yarn is easily detached from the ring, and the bent portion 3b is bent by an arc having a certain radius, and the tip 3a is bent. If the thread is extended so as to be wound inside the bent portion, the thread is difficult to be detached.

At the center of the yarn supply holder 19, an output shaft 15 is provided.
A change motor 16 is mounted so as to face the yarn guide 9. The change motor 16 rotates the output shaft 15 by 180 degrees according to a drive signal given at a predetermined timing. The axis of the output shaft 15 coincides with the pivot 6, and the ballooning guide 5 aligns the main rod 10 with the pivot 6,
The base end is fixed to the output shaft 15. When the change motor 16 is stopped, one of the two rings of the ballooning guide is on one of the yarn pulling shafts of the yarn feeder, and the other is on the other yarn pulling shaft of the yarn feeder. .

A change sensor 17 for detecting from which side the yarn enters the yarn guide 9 is provided on the yarn entry side of the yarn guide 9, that is, on the yarn supply holder side.
Further, on both sides of the change motor 16, a tail tensor 18 that holds an intermediate position of a yarn (pick tail yarn) that connects the yarn feeders to each other is attached.

Next, the operation of the apparatus of the above embodiment will be described with reference to FIGS. The yarn is pulled out from the yarn supplying body 1A in which the ring 3A on the leading end side is located on the yarn drawing shaft,
It is supplied through the distal ring 3A and the yarn guide 9.
The yarn unwound from the yarn supplying body 1A is drawn out while the ballooning is controlled by guiding the yarn along the inner periphery of the ring 3A (see FIG. 1 or FIG. 5).
(State shown in (a)). A drive signal is supplied to the change motor 16 at a timing when the yarn drawing progresses and the diameter of the yarn supplying body is reduced, and the ballooning guide 5 is rotated by 180 degrees around the turning shaft 6 in a direction opposite to the ballooning direction of the yarn. I do. The above timing is set by measuring the yarn feeding time from the yarn unwinding with a timer, or detecting the diameter of the yarn feeder 1A with a photoelectric sensor or the like.

Along with this rotation, the ring 3A on the distal end moves from the yarn pull-out shaft 7 of the yarn supplying body 1A, and when the state shown in FIG. 4B is reached, the yarn 14 is bent by the movement of the ring 3A. An outward force is applied at the same time as the centrifugal force, and the yarn separates out of the ring through the through slit 13 (see FIG. 5B). Thereafter, the intermediate ring 3B immediately advances on the yarn pull-out shaft, collides with the side surface of the intermediate branch rod 11B into which the yarn has entered due to the ballooning operation of the yarn, and is drawn toward the intermediate ring 3B along with the ballooning operation. Then, it is drawn into the intermediate ring 3B through the through slit 13 (see FIGS. 4C and 5C). In this way, the yarn is captured by the intermediate ring 3B, and ballooning is controlled by the intermediate ring (see FIG. 5C).
, The yarn supply is continued. At this time, the ring 3A on the leading end side is located on the yarn pull-out shaft of the other yarn supplying body 1B.

When all the yarns of the yarn supplying body 1A are unwound, the yarn to be pulled out is swung in the extending direction of the pick tail yarn 20, and by this operation, the yarn passes through the through slit 13 of the intermediate ring and is pulled out of the ring. And the yarn is unwound from the outer periphery of the other yarn feeder 1B. When the yarn is unwound from the other yarn supplying body, the yarn unwound by the orbiting operation collides with the side surface of the branch rod 11A of the ring 3A on the leading end side on the yarn drawing shaft, and the rotation shaft operation is started. Along with this, it moves to the tip of the branch rod and is guided from the through slit 13 to the inside of the ring 3A on the tip side. Since the change sensor 17 detects that the yarn has moved from the yarn supplying body 1A to the other yarn supplying body 1B,
For example, if a drive signal is given to the change motor 16 by a timer, the timer is reset and a new yarn feeding time is counted, so that the conversion is performed at the same timing as in the case of the previous yarn feeder. The tip ring 3A and the intermediate ring 3B are also exchanged for the later yarn supply body.

While the yarn is being pulled out from the other yarn feeder 1B, the paper tube of the empty yarn feeder is removed, a new yarn feeder is loaded, and the subsequent yarn feeder is loaded. By connecting the end of the thread of the thread body 1B to the tip of the thread of the new thread supplying body and engaging the pick tail thread to the tail tensor 18B, it is possible to supply a thread of substantially infinite length. .

FIG. 6 shows a state in which the yarn is pulled out in the state of FIG.
And the yarn tension 22 when the yarn is controlled only by the intermediate ring 3B, that is, when the yarn is controlled only by the intermediate ring 3B. The diameter is schematically shown. Thread tension line 2 in FIG.
By converting the ring 3A on the distal end side and the intermediate ring 3B at the timing 23 (diameter of the yarn feeder) at which the line of the yarn tension 22 intersects with the line 1, the diameter of the yarn feeder accompanying the unwinding of the yarn is reduced The change in the tension of the yarn caused by the decrease can be reduced.
As shown in FIG. 7, when the ring 3 is disposed such that the inner periphery of the ring is located on a line drawn at 45 to 60 degrees from the outer peripheral end of the yarn supplying body, good ballooning control characteristics are obtained. Can be

6 and 7, as the number of rings increases, the change in tension of the unwound yarn decreases. For example, when using a large-sized yarn supplying body having a large diameter change from the start of unwinding to the end of unwinding, it is desirable to increase the number of rings.

FIGS. 8 and 9 show a second embodiment using three rings. The ballooning control guide 5 comprises:
Three branch rods 11 that branch off from the main rod 10 at radially different angles of 120 degrees from each other and at axially different positions.
A, 11B, and 11C, and rings 3A, 3B, and 3C formed at the ends thereof in the same manner as in the first embodiment. Further, the yarn supply holder 19 is provided with three yarn supply bodies 1A, 1A, 1A so that the yarn pull-out shaft 7 of each yarn supply passes through the yarn guide 9 which is an extension of the main rod 10 of the ballooning guide.
B and 1C are held. The change motor 16 is installed on the yarn supply holder, and rotates the output shaft 15 by 120 degrees when a drive signal is given. The yarn feeder is located on the yarn pulling-out axis. The rotation direction of the output shaft of the change motor 16 is the direction opposite to the direction of the ballooning of the yarn to be pulled out, and the rotation of the change motor 16 causes the tip of the output shaft on the yarn pull-out shaft of the yarn feeder from which the yarn is drawn out. Side ring 3A, middle ring 3B
And the base ring 3C enters in this order.

In the case of the second embodiment in which three rings are provided, the ballooning control is switched between three stages in accordance with a decrease in the diameter of the yarn supplying body 1 as shown in FIG. Therefore, a change in the tension of the yarn due to a change in the diameter of the yarn supplying body can be further reduced as compared with the first embodiment in which the two stages are switched.

In the example shown in the embodiment (FIGS. 1 and 8), the yarn supply is performed while the yarn supply holder 19 is stationary, but a structure in which the yarn supply body 1 is rotated around the turning shaft 6 is employed. It is also possible to adopt. In FIG. 8, after the yarn is converted from the first yarn supply to the second yarn supply, the yarn supply holder 19 is rotated in the same direction as the rotation of the change motor 16 while the change motor 16 is stopped, and the yarn is actually released. Moving the wound yarn supply so as to maintain the position of the yarn supply at a fixed position improves the workability of loading a new yarn supply into the yarn supply holder.

FIGS. 10 and 11 show an example of the third embodiment (claim 2) of the ballooning control guide. This is the main rod 1
A ballooning control guide 5 in which rings 3 and 4 of different diameters for inserting a thread through the ends of a plurality of branch rods 11 extending radially from 0 are arranged at the same height in the axial direction of the main rod 10,
The shapes of the branch rod and the ring, and the relative positional relationship and operation between the yarn feeder 1 are the same as in the first and second embodiments.

As shown in FIG. 11, a ring 4 having a large ring diameter corresponds to a large diameter of the yarn supplying body 1, and a ring 3 having a small ring diameter corresponds to a small diameter of the yarn supplying body 1. By rotating the main rod 10 intermittently, the unwinding tension of the yarn is made substantially uniform as in the above-described example, and the phenomenon that several windings at the yarn drawing-out side end of the yarn supplying body slips off and the yarn breakage is prevented.

As shown in FIG. 7, when determining the ring diameter, if the inner circumference of the ring is positioned on a line drawn at 45 to 60 degrees from the outer peripheral end of the yarn supplying body, good ballooning control can be achieved. Characteristics are obtained.
