  Next, embodiments of the invention will be described. FIG. 1 is a perspective view showing an overall configuration of a combined yarn winding system according to an embodiment of the present invention, and FIG. 2 is a sectional side view showing a state and arrangement of a yarn switching mechanism.

  FIG. 1 shows an overall perspective view of the combined yarn winding system. The combined yarn winding system 1 is unwound from a creel 10 on which a large number of yarn supply packages 5, 5,. A winding machine 2 for forming a combined yarn package K by combining and winding three yarns Y is provided.

  The combined yarn winding system 1 includes a yarn switching box 12 as a housing for accommodating a plurality of yarn switching mechanisms 3 between the creel 10 and the winder 2. In this embodiment, the yarn switching mechanism 12 is provided in the yarn switching box 12 in a state where three yarn switching mechanisms 3 are arranged in the vertical direction.

  The creel 10 is a parallel creel, and the yarn supply package 5 mounted on the creel is configured as a fixed creel that is not moved. As shown in FIG. 2, in the present embodiment, the creel 10 is configured so that a total of 18 yarn supply packages 5 in six rows in the horizontal direction and three levels in the vertical direction can be placed.

  As shown in FIG. 1, the yarn feeding package 5 is a cone-shaped package, and several yarn feeding packages 5 (six yarn feeding packages 5 in this embodiment) having different yarn colors or yarn types from each other are provided. In summary, one package group 4 is formed. For example, when different yarn colors are used, the first yarn supply package 5 is red, the second is yellow, the third is blue, and so on. The creel 10 is configured so that the number of package groups 4 corresponding to the number of yarns to be combined can be set. Specifically, since the yarns to be combined in the present embodiment are three as described above, three package groups 4 (3 × 6 = 18 in terms of the number of yarn supply packages 5) are arranged. It is configured so that it can be set. Each of the three package groups 4 is provided so as to correspond to each of the later-described yarn switching mechanisms 3 provided in the same manner.

  The yarn switching box 12 has a configuration in which the inner space is partitioned into three in the longitudinal direction. As shown in FIG. 1, each of the compartments P, P,. The yarn switching mechanism 3 including a selection device 7 and a knotter (yarn joining device) 8 is accommodated. In the following, in order to identify each of the three yarn switching mechanisms 3, description will be given with numbers 1 to 3 counted from the top (# 1 to # 3).

  Reference numeral 9 in FIG. 1 is a sensor for detecting thread breakage, and one sensor 9 is arranged for each thread switching mechanism 3.

  As shown in FIGS. 1 and 2, the yarn groups Y, Y... That are unwound from the corresponding package group 4 are supplied to the respective yarn selection devices 7 of the yarn switching mechanism 3. That is, a total of six yarns Y, Y... Are unwound from each of the six yarn supply packages 5 of various yarn colors constituting the corresponding package group 4, and these six colors are colored. Are supplied to the yarn selection device 7 of the corresponding yarn switching mechanism 3 via an appropriate yarn guide.

  As shown in FIG. 1 and FIG. 2, one (or a plurality) of yarn groups Y, Y... That are appropriately selected by the yarn selection device 7 among the yarn groups Y, Y. Only the yarn Y) is supplied to the winder 2 side.

  The above-described yarn selection device 7 has the same configuration as the yarn selection device disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-156185, and will be briefly described below with reference to FIG. This thread selection device 7 includes six thread guides 17, 17... Corresponding to the number (6) of yarns Y, Y. A cylinder (not shown) that can be individually rotated up and down, a suction nozzle (suction means) (not shown) that can suck the yarn Y, and hold the yarn end of the yarn Y against this suction to stand by. And a holding roller 18 capable of being used.

  Each yarn guide 17 is provided in a cylindrical shape, and the supplied yarn Y can be inserted into the inside thereof. Each of the six thread guides 17 can be independently switched between the raised position (selected position) and the lowered position (selection release position or retracted position) by the cylinder.

  The knotter 8 is provided immediately downstream of the yarn selecting device 7. Since the configuration of the knotter 8 is a general one, for example, a known knotter disclosed in Japanese Patent Application Laid-Open No. 2004-156185 can be adopted, and detailed description thereof is omitted.

  Hereinafter, the switching of the yarn Y by the yarn switching mechanism 3 (the yarn selection device 7 and the knotter 8) having this configuration will be described. As shown in FIG. 2, the six yarns Y, Y,... Introduced into the yarn selection device 7 of each yarn switching mechanism 3 are the yarn guides 17, 17. One is inserted through each. Then, the yarn selection device 7 selects one or a plurality of yarns Y out of the six yarns, and the yarn guide 17 corresponding to the selected yarn Y is set to the upper selection position and the yarn not selected. The cylinder is controlled so that the Y yarn guide 17 is in the lower retracted position.

  Here, when the yarn guide 17 is switched to the selected position, the yarn Y guided by the yarn guide 17 can deliver its yarn end to the downstream knotter 8. On the other hand, when the yarn guide 17 is in the retracted position, the yarn end of the yarn Y is not delivered to the knotter 8 but is held by the holding roller 18 and waits.

  In the yarn switching mechanism 3 having this configuration, when the yarn Y currently selected and supplied to the winder 2 side is switched to the yarn Y of a different color (or yarn type), the cylinder is driven and the current supply is performed. The yarn guide 17 corresponding to the yarn Y being moved is lowered to the retracted position, while the yarn guide 17 guiding the newly selected yarn Y is raised from the retracted position to the selected position. Then, the current yarn Y is cut by the knotter 8, and the cut yarn end (yarn end on the winder 2 side) and the new yarn Y are spliced. Note that the yarn end of the yarn Y that is no longer selected (the yarn end on the yarn supply package 5 side) is automatically held by the holding roller 18 and waits in preparation for the yarn Y being selected again later. . In this way, the color (or yarn type) of the yarn Y supplied to the winder 2 side can be switched.

  The yarns Y, Y, and Y selected by the yarn selection device 7 and drawn from the three yarn switching mechanisms 3 are sent to the guide 13 as shown in FIG. The yarn is wound and wound by a predetermined length by the winder 2 to form a combined yarn package K. In addition to or in place of the guide 13, a tensor for applying tension to the yarn may be provided.

  The winder 2 includes a cradle 15 that rotatably supports the bobbin 14 and a contact drum 16 that rotates in contact with a yarn layer formed by winding a yarn (synthetic yarn) around the bobbin 14. ing. A traverse groove 22 is formed on the peripheral surface of the contact drum 16 so that the contact drum 16 can be traversed by engaging with the combined yarn.

  The combined yarn winding system 1 includes an electric motor (motor) 19 for driving the contact drum 16. The electric motor 19 is configured as a motor capable of angle control, such as a pulse motor or a servo motor. Yes. The electric motor 19 is connected to a controller (winding controller) 20 of the winder 2, and the winding controller 20 controls the rotation and stop of the electric motor 19. The winding controller 20 is connected to a host system controller (control device) 21 for overall control of the combined yarn winding system 1.

  Then, when a predetermined length of yarn (combined yarn) is wound on the bobbin 14 by the rotational drive of the winder 2 by the electric motor 19, the winder 2 is doffed by a doffing mechanism (not shown). This is so that the next new bobbin 14 can be combined and wound up again.

  Further, in the combined yarn winding system 1 of the present embodiment, as shown in FIG. 1, the system controller 21 is electrically connected to each of the three yarn switching mechanisms 3, and the yarn switching mechanisms 3 are individually connected. It is configured so that it can be controlled. Although not shown in detail, in this embodiment, the system controller 21 is configured in a known microcomputer type, and includes a CPU as a calculation means and a ROM and RAM as storage means, and the winding controller 20 and the yarn switching function. An output unit for outputting a control signal for the mechanism 3 is provided.

  In the system controller 21, information on the winding length of the combined yarn package K is set in advance, and this length information is stored in storage means such as a RAM. Then, the system controller 21 transmits a command to the winding controller 20 to drive the winder 2 by the stored length. Receiving this command, the winding controller 20 calculates the rotation angle of the contact drum 16 corresponding to the commanded winding length, and controls to drive the electric motor 19 of the winder 2 by this rotation angle. . Thus, the contact drum 16 is rotated by a predetermined rotation angle, and the yarn Y can be wound up while being combined to form a predetermined length of the combined yarn package K.

  Further, the system controller 21 inputs and sets information (switching information) of the switching position of the yarn Y and the switching destination yarn Y for each of the three yarns Y, Y, and Y to be combined, and this setting is performed. The stored information can be stored in a storage means such as a RAM.

  Taking the above switching information as an example, “At the beginning of winding, the first to third yarns Y are all blue. And at the point 180 cm from the beginning of winding, the first yarn Y is yellow. The second yarn Y is switched to red, and only the first yarn Y is switched to white at a point 230 cm from the beginning of winding. Note that the number of the yarn Y mentioned in the above example (No. 1 to No. 3) corresponds to the number assigned to the yarn switching mechanism 3 (No. 1 to No. 3, # 1 to # 3) in this embodiment. It is attached to do.

  Based on the switching information, the system controller 21 rotates the contact drum 16 of the winder 2 by a rotation angle corresponding to the distance from the winding start to the switching point, and then the yarn corresponding to the yarn Y to be switched. Only the switching mechanism 3 (yarn selection device 7 and knotter 8) is selectively operated to switch the yarn Y.

  A specific example of control based on the above switching information example will be described. At first, the system controller 21 sends a signal to the first to third yarn switching mechanisms 3 to send the first to third yarns Y, Y, and Y. For Y, the blue yarn Y is selected and supplied. Thereafter, the system controller 21 drives the electric motor 19 via the winding controller 20 to start winding the yarn Y around the bobbin 14, and the contact drum 16 until the position of the yarn switching mechanism 3 corresponds to a point 180 cm from the start of winding. Drive to stop. Thereafter, the system controller 21 sends a yarn switching command signal to the first and second yarn switching mechanisms 3 to switch the first yarn Y to yellow and the second yarn Y to red.

  At the time of the above switching, the third thread switching mechanism 3 does not perform the switching operation. In other words, at the point 180 cm from the beginning of winding, only the first and second thread switching mechanisms 3 among the three thread switching mechanisms 3 are selectively operated. However, this is because the thread switching information to that effect is set. For example, when thread switching information is set to switch all of No. 1 to No. 3 to red, from No. 1 All three yarn switching mechanisms 3 up to No. 3 are operated.

  After the switching is completed, the electric motor 19 is driven again, and this time, the winder 2 is driven and stopped until the yarn switching mechanism 3 reaches a rotation angle located at a point of 230 cm from the start of winding. Thereafter, the system controller 21 sends a yarn switching command signal to the first yarn switching mechanism 3 to selectively operate it, and switches the yarn Y to white for the first yarn Y that the yarn switching mechanism 3 is responsible for.

  By controlling in this way, it is possible to change the color and yarn type in the length direction for each single yarn Y to be combined while one single yarn package K is being wound. Design can be realized.

  Further, in the present embodiment in which the number of knots 8 corresponding to the number of yarns to be combined (three) is provided, each knotter 8 needs to handle only one yarn Y out of the three. When the yarns Y are simultaneously switched, they can be shared by the respective knotters 8 in a short time. Further, since one knotter 8 is responsible for switching one yarn Y on a one-to-one basis, the control on the system controller 21 side can be simplified.

  Further, in the present embodiment, since the switching portion is positioned by controlling the rotation angle of the contact drum 16 in the winder 2, it is possible to reduce the deviation of the switching position of the yarn Y between the yarns to be combined, which is intended. Textiles can be expressed accurately. Moreover, in this embodiment, since it is the structure which measures length with the rotation angle (rotation amount of the contact drum 16) of the electric motor 19 of the winder 2, a special length measuring device becomes unnecessary and it contributes to simplification of a structure. be able to.

  As described above, in the combined yarn winding system 1 of the present embodiment, a creel 10 capable of setting a plurality of yarn supply packages 5, 5... For supplying the yarn Y, and a plurality of the creel 10 supplied from the creel 10. A winder 2 that combines the yarns Y, Y... A yarn switching mechanism 3 including a yarn selection device 7 and a knotter 8 that joins the yarn selected by the yarn selection device 7 is formed between the creel 10 and the winder 2. A plurality of yarn groups Y, Y... Further, the creel 10 is configured so that a package group 4 composed of a plurality of yarn supply packages 5 having different colors can be set in correspondence with each of the yarn switching mechanisms 3. .. Are supplied from the package group 4 to the yarn selection device 7 of the yarn switching mechanism 3, and the yarn selection device 7 is supplied with the supplied yarn group Y.Y. .. Are selected and supplied to the winder 2 side.

  As a result, each of the yarns Y, Y, and Y to be combined can be switched by the yarn switching mechanism 3, so that it is possible to flexibly cope with a change in the configuration of the yarn Y to be combined, which is extremely useful for high-mix low-volume production. A suitable combined yarn winding system 1 can be realized.

  Further, in the present embodiment, while the combined yarns Y, Y, and Y are being wound up by the winder 2, all or a part of the plurality of yarn switching mechanisms 3 are operated, A system controller 21 is provided for controlling the selection of the yarn Y to be sent to the winder 2 side.

  As a result, since each of the yarns Y to be combined can be switched by the respective yarn switching mechanisms 3 while being wound around the package K, a novel and varied textile can be easily realized.

  In the combined yarn winding system 1 of the present embodiment, the first to third yarn switching mechanisms 3 are arranged in parallel in the vertical direction. Thereby, the compact layout of the combined yarn winding system 1 is realized, and the installation space can be reduced.

  Further, in the present embodiment, the combined yarn winding is realized by the following method. That is, the yarns Y, Y,... Are supplied from a plurality of yarn supply packages 5,... Mounted on the creel 10, and a plurality of yarns Y, Y, Y are combined and wound by the winder 2. Wind up on package K. Then, the creel 10 is provided with a package group 4 composed of a plurality of yarn supply packages 5. The yarn groups Y, Y,... Unwound from the package group 4 are supplied to each of the yarn selection devices 7 provided one by one corresponding to each package group 4, and in each yarn selection device 7, It is configured to select at least one yarn Y from the supplied yarn group Y, Y... And supply it to the winder 2. Further, a knotter 8 for piecing the yarn selected by the yarn selection device 7 is provided so as to correspond to the yarn selection device 7 on a one-to-one basis.

  By this method, each of the yarns Y, Y, and Y to be combined can be switched by the yarn selection device 7, so that it is possible to flexibly cope with a change in the configuration of the yarn Y to be combined, and for high-mix low-volume production. A very suitable method for winding a combined yarn can be obtained.

  In the above-described combined yarn winding method, the combined yarns Y, Y, and Y are wound by the winder 2 to form the package K, and all or a plurality of the yarn selection devices 7 are selected. The selected portion is operated to switch the selection of the yarn Y to be sent to the winder 2 side.

  According to this method, the yarns Y, Y, and Y to be combined can be switched by the respective yarn selection devices 7 in the middle of being wound around the package K, so that a variety of innovative textiles can be easily made. Can be realized.

  Although the preferred embodiment of the present invention has been described above, the above embodiment can be modified as follows, for example.

  (1) The three yarn switching mechanisms 3 (No. 1 to No. 3) arranged in parallel in the vertical direction are set as one set, and the set of the yarn switching mechanisms 3 is set in the horizontal direction (that is, the parallel arrangement of the yarn switching mechanisms 3). A plurality of winders 2 may be arranged in a direction parallel to the direction in which the set is arranged, and a plurality of spindles may be wound. In this case, one thread switching box 12 may be provided for each group of three thread switching mechanisms 3, or a plurality of sets of thread switching mechanisms 3 may be stored together in one thread switching box 12. good. One creel 10 may be provided for each pair of the thread switching mechanisms 3, or a plurality of pairs of the thread switching mechanisms 3 may be handled by one creel 10. In the case of the above configuration, it is possible to realize a simple and compact layout in which a plurality of spindles are wound together.

  (2) In the above embodiment, the knotter 8 is employed as the yarn joining device. However, other yarn joining devices such as a splicer may be employed instead of the knotter 8. Further, although the creel 10 is a parallel creel in this embodiment, another arrangement method may be adopted. Furthermore, a tension device that adjusts the tension of the yarn Y may be provided at an appropriate position in the course of the creel 10 and the yarn Y.

  (3) In the above embodiment, the same number of three yarn switching mechanisms 3 as the number of yarns to be combined are provided. However, at least three yarn switching mechanisms 3 may be used. For example, a spare yarn switching mechanism 3 is added in case of failure. As a result, of course, the total number of yarn switching mechanisms 3 may exceed the number of yarns to be combined.

  (4) The yarn selection device 7 does not necessarily select one yarn Y. For example, in the yarn selection device 7 of the first yarn switching mechanism 3, if two of the six yarn guides 17 and 17 are set to the selected position, two yarns Y and Y are simultaneously wound from the first yarn switching mechanism 3. It is possible to feed a total of four yarns together with the yarn Y from the other yarn switching mechanism 3 by supplying to the take-up machine 2 side. Thereby, more various textiles can be realized.

  (5) In the above embodiment, the yarn switching mechanism 3 is configured by the yarn selecting device 7 and the knotter 8, but the yarn switching mechanism 3 may further include a yarn storage device capable of storing the yarn Y. In this case, since the time for stopping the rotation of the winder 2 for switching the yarn Y during the formation of the combined yarn package K can be reduced or zero, productivity can be improved.

  (6) In the above embodiment, the length of the yarn Y is measured by detecting the rotation angle of the contact drum 16. For example, a length measuring roller (not shown) is attached to the yarn Y before being wound by the winder 2. It is also possible to calculate the winding length of the yarn Y by detecting the amount of rotation of the length measuring roller, and determine whether or not the switching position has been reached.

  (7) Number of combined yarns (number of package groups 4 and yarn switching mechanism 3) The number of yarn supply packages 5, 5... Constituting one package group 4 is not limited to the above, and can be changed as appropriate. can do. In addition, the colors or combinations of yarn types of the yarn supply packages 5, 5... Are arbitrary, and depending on the pattern or texture desired to be realized, only the colors can be switched among the same yarn types, or the yarns of the same color. Only the type can be switched, the color and the thread type can be switched at the same time, or various threads can be switched as necessary.
