Description

The present invention relates to a yarn winding device and a false twisting machine .

  As this type of technology, Patent Document 1 discloses a false twisting machine for twisted yarn, which is obtained by falsely twisting a yarn unwound from a yarn supply package and then winding the wound yarn around a winding tube. This false yarn twisting machine is provided with an air nozzle for each yarn on each weight. The pair of yarns to be unwound from the yarn supply package is drawn and twisted separately independently on the upstream side of the air nozzle, and is joined at the air nozzle, and is joined at the downstream side of the air nozzle. In the traverse device, the wire is wound around the winding tube.

  In the field where such a false yarn twisting machine is owned, there is a recent need to wind up the yarn unwound from the yarn supply package separately on the winding tube without combining them. However, the conventional traverse device provided for each weight is a traverse drum type traverse device in which a spiral groove is formed on the outer periphery, and a belt type traverse guide provided on the belt body. A traverse device is designed to form a single winding package for the winding tube. Therefore, when winding a pair of yarns to be unwound from the yarn feeding package separately onto the winding tube without combining them, the yarn is unwound from only one of the pair of yarn feeding packages of each weight. And the other yarn supply package must be stopped. Similarly, any one of the devices (for example, primary heater device, cooling device, false twisting device, etc.) provided in a pair on the upstream side of the air nozzle must be in a state that does not contribute to the production of the winding package. Don't be.

  In view of such circumstances, Patent Documents 2 and 3 disclose a system that can simultaneously produce two winding packages for a winding tube supported by a single cradle.

  The winder disclosed in Patent Document 2 rotates a grooved drum, rotates a bobbin by the rotation of the grooved drum, and feeds a plurality of yarns fed out from a plurality of actual bobbins to a single bobbin. A large package is formed by winding as a multi-row package portion in the direction. On the peripheral surface of the grooved drum, a pair of traverse grooves are formed independently in the width direction.

  Similarly, Patent Document 3 discloses a winding device that winds two wound balls around a cone-type bobbin. This winding device includes a traverse drum having two sets of spiral traverse grooves corresponding to the positions of winding balls wound on the bobbin as traverse means for the cone type bobbin held by the cradle. The traverse drum is driven from a motor through a belt transmission mechanism, and a bobbin is brought into contact with the traverse drum to rotate, whereby the yarns drawn from the two yarn supply packages provided at the lower portion are traversed. It winds up on a bobbin while traversing in each traverse groove of a vibration drum, and forms a wound ball of a predetermined diameter at an appropriate interval.

  At first glance, if the traverse device described in Patent Document 1 is replaced with the grooved drum disclosed in Patent Document 2 and Patent Document 3 described above (or traversing drum, hereinafter referred to as grooved drum). It seems to be able to meet the above needs and ensure high productivity. However, it is not easy to replace the grooved drum or the like, and as is well known, it takes about 1 hour per spindle, which is not practical.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a drawing false twisting machine for combined yarn according to an embodiment of the present invention. FIG. 2 is a schematic diagram in which each device included in the drawing false twisting machine for combined yarn according to one embodiment of the present invention is developed along the yarn path. In FIG. 2, only two false twisting weights are shown. The false twisting weight is hereinafter simply referred to as a weight.

  In this embodiment, the drawing false twisting machine 1000 for combined yarn includes a plurality of weights 100 arranged in the left-right direction in FIG. 2 and a control device to be described later for controlling the operation of the plurality of weights 100. Consists of.

  As shown in FIGS. 1 and 2, each weight 100 includes a yarn feeding portion 1, a false twisting portion 2, a yarn joining portion 3, a post-processing portion 4, and a winding portion 5. The yarn feeding section 1 indicates a section upstream of the first feed rollers 6a and 6b described later, and the false twisting section 2 extends from the first feed rollers 6a and 6b to the upstream second feed rollers 7a and 7b described later. It points to the section to. Similarly, the combined yarn section 3 refers to a section from the upstream second feed rollers 7a and 7b to the downstream second feed rollers 8a and 8b described later, and the post-processing section 4 includes the downstream second feed rollers 8a and 8b. This refers to a section from 8b to third feed rollers 9a and 9b described later. The winding unit 5 indicates a section downstream of the third feed rollers 9a and 9b.

  The yarn supplying unit 1 has a pair of yarn supplying packages 11 supported by a creel stand 10 shown schematically, and sends out a pair of yarns Ya and Yb. The yarns Ya and Yb sent from the yarn supply packages 11a and 11b reach the false twisting section 2 through the pipes 12a and 12b and the first feed rollers 6a and 6b.

  The false twisting unit 2 performs false twisting on the pair of yarns Ya and Yb sent from the yarn supplying unit 1. The false twisting section 2 is arranged in order from the upstream side of the yarns Ya and Yb to the primary heater 13 that heats the yarns Ya and Yb, the cooling devices 14a and 14b that cool the yarns Ya and Yb, and the yarns Ya and Yb. And false twisting devices 15a and 15b for applying twist.

  The combined yarn part 3 forms an entangled part in the yarn subjected to false twisting by the false twisting part 2, and includes interlace nozzles 16a and 16b. When the pair of yarns Ya and Yb are passed together through one of the interlace nozzles 16a and 16b (or 16a, the same applies hereinafter), the interlace nozzle 16b is connected to the yarn Ya. By forming the entangled portion with respect to Yb, the yarns Ya and Yb are combined. On the other hand, when the pair of yarns Ya and Yb are separately passed through the interlace nozzles 16a and 16b, the interlace nozzle 16a forms an entangled portion with respect to the yarn Ya, and the interlace nozzle 16b becomes the yarn Yb. An entanglement part is formed with respect to it.

  The post-processing unit 4 performs heat treatment on the yarns Ya and Yb, and includes secondary heaters 17a and 17b.

  The winding unit 5 is configured to wind a pair of yarns Ya and Yb subjected to false twisting by the false twisting unit 2 around a winding tube, and includes a winding device 18 (yarn winding device). Is done. About this winding device 18, the layout which overlaps with the winding device 18 of the other weight 100 up and down is employ | adopted from a compact viewpoint of the drawing false twisting machine 1000 for combined yarn. The winding device 18 will be described in detail later.

  With the above configuration, the weight 100 shown on the left side in FIG. 2 operates as follows.

  The yarn Ya sent from the yarn supply package 11a is composed of a pipe 12a, a first feed roller 6a, a primary heater 13, a cooling device 14a, a false twisting device 15a, an upstream second feed roller 7a, and an interlace. It winds around the winding device 18 through the nozzle 16a, the downstream second feed roller 8a, the secondary heater 17a, and the third feed roller 9a in this order.

  Specifically, the yarn feed speed of the upstream second feed roller 7a is set to be larger than the yarn feed speed of the first feed roller 6a. As a result, the yarn Ya is stretched between the first feed roller 6a and the upstream second feed roller 7a. In this state, the false feed device 15a causes the first feed roller 6a and the upstream second feed roller 7a to be stretched. Twisted between. The yarn Ya twisted while being drawn is heat-set by the primary heater 13 and then cooled by the cooling device 14a. The twisted, heat-set and cooled yarn Ya passes through the false twisting device 15a and is untwisted before reaching the upstream second feed roller 7a.

  In this embodiment, the yarn Ya that has passed through the upstream second feed roller 7a is guided to the interlace nozzle 16a, and an interlaced portion is formed by the interlace nozzle 16a, and then sent to the downstream second feed roller 8a. .

  The yarn feed speed of the downstream second feed roller 8a is set to be larger than the yarn feed speed of the third feed roller 9a. As a result, the yarn Ya is relaxed between the downstream second feed roller 8a and the third feed roller 9a, and in this state, the yarn Ya is subjected to a relaxation heat treatment in the secondary heater 17a, to the third feed roller 9a. Sent.

  In the above, the operation | movement along the path | route of the thread | yarn Ya among operation | movement of the weight 100 was demonstrated. The operation of the weight 100 along the path of the yarn Yb is the same. That is, the yarn Yb sent from the yarn supply package 11b is a pipe 12b, a first feed roller 6b, a primary heater 13, a cooling device 14b, a false twisting device 15b, an upstream second feed roller 7b, The interlace nozzle 16b, the downstream second feed roller 8b, the secondary heater 17b, and the third feed roller 9b are sequentially wound around the winding device 18.

  Next, the winding device 18 of the winding unit 5 will be described in detail. FIG. 3 is a partially enlarged view of FIG. 2 and is a schematic configuration diagram of the winding device.

  As shown in this figure, the winding device 18 includes a single cradle 20 that rotatably holds the winding tube 19, and a yarn Ya that is supplied from the yarn supply packages 11 a and 11 b and wound around the winding tube 19. A traverse device 21 that traverses Yb is provided. The weight 100 and the cradle 20 have a one-to-one relationship.

  The cradle 20 includes a pair of bobbin holders 22 and 22, and the substantially cylindrical winding tube 19 is rotatably held by the cradle 20 via the bobbin holders 22 and 22. The cradle 20 is pivotally supported at one end by a machine base (not shown), and the take-up tube 19 is wound around the take-up drum 23 so that the take-up tube 19 sandwiched between the bobbin holders 22 and 22 is rotated. Urging means (not shown) for urging toward the surface is provided. For example, a coil spring or the like is used as the biasing means. The winding drum 23 is rotated in a predetermined direction by a drive motor 24 that is schematically shown. In the present embodiment, the winding drum 23 is also used in other weights 100. That is, the illustrated winding drum 23 actually extends further in either the left or right direction of the paper surface.

  The traverse device 21 includes a belt body 26 that reciprocates by a drive motor 25 that is schematically shown, and two traverse guides 27a and 27b that are provided on the belt body 26 and guide the yarns Ya and Yb. In the present embodiment, the belt body 26 is a toothed belt having a large number of teeth on the inner periphery, and is wound around a drive pulley 28 rotated forward and backward by the drive motor 25 and a pair of driven pulleys 29 and 29. . The travel path of the belt body 26 between the pair of driven pulleys 29 and 29 is substantially parallel to the axis of the winding tube 19. The traverse guides 27 a and 27 b are provided on the belt body 26 with a predetermined interval between one and the other of the driven pulleys 29. In the present embodiment, the “predetermined interval” is determined to be equal to the pitch of the packages P and P formed as a pair with respect to the winding tube 19. That is, the pitch of the packages P and P formed as a pair with respect to the winding tube 19 is determined depending on the “predetermined interval”. On the upstream side of the traverse device 21, a yarn guide 30a for changing the yarn path of the yarn Ya sent from the third feed roller 9a to the front of the traverse center of the traverse guide 27a, and a feed from the third feed roller 9b. And a yarn guide 30b for changing the yarn path of the yarn Yb to be moved to the front of the traverse center of the traverse guide 27b. A thread guide 30c is further provided between the thread guides 30a and 30b.

  The traverse guides 27 a and 27 b are configured to be detachable from the belt body 26. Reference is now made to FIG. FIG. 4 is a partially enlarged view of a traverse apparatus according to an embodiment of the present invention. Reference numeral 40 denotes a machine frame of the winding device 18 that pivotally supports the driven pulleys 29 and 29. As shown in this figure, the traverse guide 27a and the traverse guide 27b have substantially the same shape, and therefore the configuration of the traverse guide 27a will be described below.

  The traverse guide 27 a includes a hook-shaped guide portion 31 for guiding the yarn Ya, and a guide support portion 32 that fixes the guide portion 31 to the belt body 26. The guide support portion 32 is formed with a belt accommodation groove 33 for accommodating the belt body 26. On the side surface of the guide support portion 32, a protrusion 3 4 that extends in parallel with the traveling direction of the belt body 26 is provided. The protrusion 34 is inserted into a rail (not shown) extending in parallel with the axis of the winding tube 19 so that the traverse guide 27a can stably reciprocate in parallel with the axis of the winding tube 19. Thus, the guide portion 31 is prevented from being shaken. Reference is now made to FIG. FIG. 5 is a horizontal sectional view taken along the line II of FIG. As shown in the figure, a fitting portion 35 is formed on the inner surface of the belt receiving groove 33 to be fitted with a plurality of tooth rubbers 26a protruding at a predetermined pitch on the inner periphery of the belt body 26. The The belt housing groove 33 is formed narrow so that the belt body 26 inserted into the belt housing groove 33 is slightly compressed in the thickness direction. Due to the compressive deformation of the belt body 26, the belt housing groove 33 and the belt body 26 are strongly adhered, and this adhesion greatly contributes to preventing the belt body 26 from coming out of the belt housing groove 33.

  Next, the control device 1001 common to each weight 100 will be described. Please refer to FIG. 3 again. As shown in the figure, the control device 1001 includes an arithmetic processing unit 50 such as a CPU that performs predetermined arithmetic processing, a storage unit 51 such as a RAM and a ROM, and a drum that controls the operation of the drive motor 24. The motor driver 52, a pulley motor driver 53 that controls the operation of the drive motor 25, and input means 54 for inputting various setting values to the arithmetic processor 50. The input means 54 is, for example, a keyboard or a mouse. In addition, the control device 1001 includes a display that displays various setting values. This display is, for example, a liquid crystal display. The arithmetic processor 50 is connected to a storage unit 51, a drum motor driver 52, a pulley motor driver 53, and input means 54. The storage unit 51 stores operating conditions of the traverse device 21. This operating condition includes the winding width of the package P, and this operating condition is shared by the plurality of weights 100.

  Said input means 54 is comprised so that the operator of the drawing false twisting machine 1000 for a combined yarn can input the operating condition of the traverse apparatus 21 to the control apparatus 1001. FIG. Then, when the set value is input to the control device 1001 via the input means 54 by the operator, the arithmetic processing unit 50 uses the current set value already stored in the storage unit 51 based on the input set value. The setting value is changed. In addition, the input means 54 allows the operator to input the winding conditions such as the setting of the doffing conditions common to all the spindles of the false twisting machine 1000, the yarn traveling speed, the winding width, the twill angle, the end face shape of the package, etc. In addition, all the spindles are controlled collectively.

  With the above configuration, winding of the yarns Ya and Yb is performed as follows. FIG. 3 shows a state where the packages P and P are already formed on the winding tube 19 in the winding device 18 to some extent. In the state shown in FIG. 3, the yarn Ya fed from the third feed roller 9a passes through the yarn guide 30a and reciprocates in parallel with the axis of the winding tube 19 by the reciprocating travel of the belt body 26. Is wound around the package P which is brought into contact with the rotating take-up drum 23 while being traversed. The same applies to the yarn Yb. Eventually, when the packages P and P are fully wound, the yarn Ya and Yb are cut between the third feed rollers 9a and 9b and the packages P and P, and the doffing mechanism (not shown) rotates the cradle 20. The packages P and P are separated from the winding drum 23 and doffed. Before and after the doffing, the reciprocating motion of the traverse guides 27a and 27b is switched to a slow motion. When the empty winding tube 19 is supplied to the cradle 20 and is sandwiched between the bobbin holders 22 and 22, the cradle 20 is rotated and the winding tube 19 is in contact with the winding drum 23. To do. When the winding tube 19 starts to rotate due to contact with the winding drum 23, the arithmetic processor 50 refers to the set value of the operating condition of the traverse device 21 stored in the storage unit 51, and based on this set value. The traverse guides 27a and 27b are reciprocated at a high speed at a predetermined reciprocating distance. Thereafter, the operator threads the yarn ends of the yarns Ya and Yb onto the winding tube 19. In this way, the winding of the desired winding width is resumed. In order to form the bunch windings B and B on the winding tube 19 in advance before forming the packages P and P, when the yarn end is threaded on the winding tube 19, the threading position is set. What is necessary is just to set it as the position away from the traverse center suitably.

  As described above, the operation of the weight 100 when the yarns Ya and Yb are separately wound independently of the winding tube 19 and the two packages P and P are simultaneously formed on the winding tube 19 is described. explained.

  Next, a procedure for changing the number of packages P formed on the winding tube 19 from two to one will be described. FIG. 6 is a view similar to FIG.

  In such a case, when the machine base is stopped, the operator inputs setting of operating conditions in the control device 1001, and changes the traverse guide for each cone to one. Thereafter, the operation of the machine base is started, and the operator hangs the yarns Ya and Yb pulled out from the yarn supply packages 11a and 11b by a normal means, and combines the combined yarns Yg as shown in FIG. Wind up on package P.

  When changing the operating conditions, the traverse guide origin is automatically recognized at the start of the operation so that the traverse guide 27b reciprocates with the set winding width. For example, the center position (origin) of the traverse width is recognized by rotating the drive pulley 28 forward and backward at low speed at the start of operation and reciprocating between the position confirmation members provided near both ends of the traverse width. Then, the travel distance of the traverse guide from the origin position to the left and right, that is, the rotation angle of the drive motor 25 of the drive pulley 28 is calculated, and the forward / reverse rotation of the drive motor 25 is controlled according to the winding width of the new package. The

  The procedure for changing the number of packages P formed on the winding tube 19 from two to one has been described above. Next, a procedure for changing the number of packages P formed on the winding tube 19 from one to two will be described. The description overlapping with the above description will be omitted as appropriate.

  In such a case, when the machine base is stopped, the operator inputs an operation condition setting in the control device 1001, and changes the traverse guide for each cone to two. Thereafter, the operation of the machine base is started, and the operator hangs the yarns Ya and Yb drawn from the yarn supply packages 11a and 11b by usual means, and the yarns Ya and Yb are two packages P as shown in FIG. -Roll up to P.

  When the operating conditions are changed, the origin of the traverse guide is automatically recognized at the start of operation so that the traverse guides 27a and 27b reciprocate with the set winding width.

  The winding tube 19 in which the two packages P and P are formed as described above is used after being cut at a substantially center in the longitudinal direction in a predetermined post-process.

Can be produced at the same time. If it is desired to produce only one package P for the winding tube 19 held between the single cradle 20, the belt body 26 is replaced with another belt body provided with only one traverse guide. In this sense, the number of packages P formed on the winding tube 19 can be easily switched as compared with the case where a grooved drum or the like is employed. Further, the traverse guides 27a and 27b are reciprocated by the reciprocating travel of the belt body 26, and the reciprocating distance of the traverse guides 27a and 27b is variable. It is possible to cope with a variety of package P.

According to the above configuration, the number of the traverse guides (27a, 27b) attached to the belt body 26 can be easily increased / decreased. The time required for switching the number of packages P formed for the tube 19 can be greatly reduced.

  The winding device 18 is further configured as follows. That is, the belt body 26 is a toothed belt, and a belt housing groove 33 for housing the belt body 26 is formed in the traverse guides 27a and 27b. A fitting portion 35 that fits with the tooth rubber 26 a of the belt body 26 is formed on the inner surface of the belt receiving groove 33. According to the above configuration, smooth and reliable attachment / detachment of the traverse guides 27a and 27b to the belt body 26 can be achieved with a simple structure.

According to the above configuration, it is possible to provide the drawing false twisting machine 1000 for combined yarn that can easily switch the number of packages P formed on the winding tube 19.

  The above-described drawing false twisting machine 1000 is further configured as follows. In other words, it further includes a combined yarn portion 3 for combining the plurality of yarns Ya and Yb subjected to false twist processing by the false twist processing portion 2. According to the above configuration, the production of winding the plurality of yarns Ya and Yb that have been false twisted in the false twisting section 2 independently and the production of winding them together by combining yarns are facilitated. It is possible to provide a draw false twisting machine 1000 for switching the combined yarn.
