- the above-mentioned rotary member 47 is shaft-supported by a bearing 51 so as to rotate inside the stationary machine part 45, and provided with a balancer 52 for the branch portion 49 and an extended shaft portion 53.
- a cylinder-shaped yarn length-measuring/storing member 55 is attached to this extended shaft portion 53 through a bearing 54.
- a magnetic force connecting means 56 is placed between the yarn length-measuring/storing member 55 and the stationary machine part 45 so that the yarn length-measuring/storing member 55 is connected to the stationary machine part 45 by the magnetic force connectingme ans 56 through a magnetic force so as to be maintained in a stationary state even during rotation of the rotary member 47.
- the yarn length-measuring/storing member 55 is provided with a storing drum unit 57 that tilts in a manner so as to narrow toward one end 55a, with a stopper flange 58 being attached to the narrowed tip end.
- a first position sensor 59 and a second position sensor 60 used for detecting the amount of wound yarn that is wound around the storing drum unit 57 are placed, and a yarn guide 61 for guiding the yarn to be drawn from the storing drum unit 57 is also installed.
- the yarn length-measuring/storing device 20 having the above-mentioned arrangement, during a drawing time of the yarn Y, when the branch portion 49, placed on one end of the rotary member 47, is allowed to rotate around the yarn length-measuring/storing member 55 by the rotary driving operation of the independent rotation driving source M1, the yarn Y, drawn from the branch portion 49 of the rotary member 47, is successively fed in arrow a direction along a taper face of the storing drum unit 57 in the yarn length-measuring/storing member 55, and temporarily stored before it is wound around the take-up package.
- the above-mentioned rotation driving source M1 may be a stepping motor or a servomotor in place of the pulse motor.
- first and second position sensors 59 and 60 that are set so as to detect the amount of yarn Y that has been fed to the storing drum unit 57 to be wound thereon in the yarn length-measuring/storing member 55 of the yarn length-measuring/storing device 20, the first position sensor 59 checks a station 57b that is apart from a yarn winding start position 57a by a distance ⁇ in the storing drum unit 57, that is, a station which is used for detecting a position of the yarn that has been stored in a manner so as not to cause lacking of yarn on the storing drum unit 57 while the next selected yarn is being joined, and for detecting whether or not any yarn exists at the station, and outputs the resulting detection signal to the control unit 16.
- the first position sensor 59 detects a state in which the yarn having a length corresponding to the axis direction distance ⁇ remains on the storing drum unit 57 as a no-yarn state.
- the second position sensor 60 detects whether or not any yarn exists on a fully wound station 57c in the storing drum unit 57, and outputs the resulting detection signal to the control unit 16.
- the types of yarns to be wound, and lengths of said types of yarns are inputted to and set in the control unit 16 in addition to the order of the yarns to be wound.
- the length of the selected yarn is automatically converted to a number of pulses to be outputted to the pulse motor M1 or set as a number of pulses. Since the circumferential length of the storing drum unit 57 has been preliminarily known, the length of the yarn to be wound is set as a number of pulses based upon the number of pulses required for one rotation of the pulse motor M1 and the circumferential length. Therefore, the length of the yarn to be wound is set by a unit of mm.
- the pulse motor M1 In a normal winding operation, when the selected yarn has been wound around the storing drum unit 57 by the length that has been determined, the pulse motor M1 is stopped by an instruction from the control unit 16, while the next predetermined type of yarn is selected, and joined to the leading yarn. During said yarn-joining operation, a motor M2 on the take-up unit 15 side continues to rotate so that the yarn stored in the storing drum unit 57 is wound up by a package P. Upon completion of the yarn-joining process, the pulse motor M1 is again driven, and rotates by the number of pulses corresponding to the set length of the newly stored yarn. In this manner, the yarns of the predetermined types and lengths are wound up on packages P.
- the storing speed (rotation speed of the motor M1) is greater than the winding speed (rotation speed of the winding-use motor M2);however,whenthe yarn-joining operations are frequently carried out, the stored yarn reduces, sometimes causing the reduction position sensor 59 to detect the no-yarn state.
- the winding-use motor M2 is temporarily stopped, and the yarn storing operation to the storing drum unit 57 is preferentially carried out.
- the winding-use motor M2 is again driven to rotate.
- the winding-use motor M2 may be driven to rotate at a reduced speed without stopping so that the storing process may be carried out while continuing the winding process.
- the amount of wound yarn on the storing drum 57 increases so that upon detection of the yarn-storing state by the position sensor 60 for detecting the maximum position, the motor M1 is stopped, and the winding process is preferentially carried out by rotating only the winding-use motor M2.
- the motor M1 is again driven to resume the storing process of yarn on the storing drum 57.
- the speed of the winding-use motor M2 is increased without stopping the motor M1 to continue the rotation; thus, the amount of stored yarn on the storing drum 57 may be reduced by increasing the winding speed.
- the detection signals indicating the yarn-storing state or the no-yarn state given by the first and second position sensors 59 and 60 are used to stop or drive the motors M1 and M2; however, since the types and lengths of yarns to be selected are preliminarily determined, the winding speed (rotation speed of the winding-use motor M2) may be set at a low speed in the case when one type of yarn the length of which is comparatively short is continuously fed, and the winding speed may be set at a high speed in the case when another type of yarn the length of which is comparatively long is continuously fed. Thus, it becomes possible to carry out an effective winding process without stopping/driving the motor.
- the yarn-processing system of the present invention relates to a yarn-joining take-up technique for different types of yarns in which different types of yarns of a plurality of kinds having, for example, different colors are yarn-joined with respectively desired lengths, while being successively selected in accordance with a preliminarily designed pattern so that the resulting yarn is wound into a package, and this system is provided with a yarn-type selection unit placed between a yarn-supplying unit and a yarn-joining unit, and the yarn-type selection unit has a yarn-type selection device which selects a succeeding yarn on the yarn-supplying side to be yarn-joined to a leading yarn on the take-up package side; thus, the yarn-joining device and the yarn-type selection device function so that the leading yarn is guided into the yarn-joining device with the leading yarn being connected to the yarn-type selection device so that the succeeding yarn is guided by a succeeding yarn guiding means into the yarn-joining device so as to be subjected to a

- the yarns on the warping drum D1 are re-wound on warping yarn beams V1 while being released (the warping yarn beam V1 is constituted by N-number of warping yarns Yb, with each warping yearn being aligned in the axis direction and wound thereon).
- a beam V2 of warping yarn Ya to be used for another sample pattern is formed, and a beam V3 of warping yarn Yc for still another sample pattern is further formed (see Patent Document 2).
- Patent Document 2 JP-A No. 11-293536 (Figs. 1 and 2)
- the respective warping yarn beams are set in a weaving machine to weave a desired sample fabric.
- each warping yarn beam is set for each sample, with the result that much time is required for preparation jobs such as a drawing process of yarns from the beams, a beam insertion process and a connecting process for yarns.
- preparation time required for warping-yarn beam exchanges and connections of warping yarns sometimes becomes longer than the process time of a weaving machine required for weaving a texture of one pattern.
- the present invention has been devised to solve the above-mentioned conventional problems, and its objective is to provide a sample warper which prepares warping yarns for a plurality of sample patterns as a single warping-yarn beam without the necessity of preparing a specific warping-yarn beam for each of the sample patterns so that the single warping-yarn beam is used for continuously weaving the sample patterns; thus, it becomes possible to greatly reduce preparation time required for setting respective warping-yarn beams in a weaving machine for the respective sample patterns.

- the yarn Y sucked onto the suction member 116, is sandwiched by a yarn holding roller 117 and a yarn holding plate 118.
- the yarn holding roller 117 is a roller member coated with an elastic member such as urethane on its circumferential surface, and the yarn holding plate 118 is made in contact with and separated from the yarn holding roller 117 by a cylinder 119.
- the yarn holding plate 118 When the yarn guide 121 is rocked during selection of the yarn, the yarn holding plate 118 is separated from the yarn holding roller 117 so that the suction member 116 is allowed to suck the yarn Y.
- the yarn holding plate 118 is made in contact with the yarn holding roller 117 by the cylinder 119 so that the yarn Y sucked onto the suction member 116 is held.

- the cylinder 125 corresponding to the yarn type to be selected is driven so that the engaging member 124 is shifted; thus, the engaging member 124 is set in such a state that it is not made in contact with the rear guide plate 122B regardless of the position thereof.
- the cylinder 127 is shrunk to set the yarn guide 121 in such a position that only the engaging member 124 is not engaged with the rear guide plate 122B; thus, the yarn guide 121 corresponding to the selected yarn type is shifted to a yarn guide station (corresponding to 121A in the drawing) used for guiding the yarn Y to the yarn-j oining device 112, and stopped at the guide position corresponding to 121B.
- the yarn that is allowed to pass through the selected yarn guide 121 has its one end held by the suction member 116, and forms a yarn YA indicated by a broken line.

- a rotary shaft 132 having a yarn passage 132b formed along the center axis inside a device main body 131 is driven to rotate by a pulse motor 137 (or a servomotor capable of angle control).
- a pulley 134 attached to the rotary shaft 132 is driven to rotate through a pulley 136 and a driving belt 135 attached to the pulse motor 137 so that the rotary shaft 132 is rotated and a winding tube 132a branched from the rotary shaft 132 is allowed to pivot around the storing drum 133.
- the yarn Y passing through the yarn passage 132b that is formed in a manner so as to penetrate the winding tube 132a from the center axis of the rotary shaft 132 is wound on the storing drum 133 that is formed in a tapered shape the diameter of which is slightly narrowed in the advancing direction of the yarn, and stored thereon.
- the yarn Y drawn from the winding tube 132a is wound around the outer diameter portion of the tapered portion of the storing drum 133 so that it is allowed to shift forward along the slightly narrowed diameter while sliding the taper portion.
- the controlling operation of the yarn length to be selected is carried out by controlling the rotation angle of the pulse motor 137 (or servomotor capable of angle control or the like) using a control device, not shown. Therefore, the length controlling operation with a fine dimension (not more than 1 cm) is available.
- the winding tube 132a is rotated by a predetermined angle so that the length of the yarn that is wound on the storing drum 133 and stored thereon is accurately controlled to the yarn length to form the pattern after the knitting process.
- the presence of the yarn Y stored on the storing drum 133 is detected by a detection sensor such as a photoelectric sensor, and in the present embodiment, a leading-portion detection sensor 139a and a rear-portion detection sensor 139b are placed.
- the rotation driving process of the winding tube 132a is temporarily stopped.
- the yarn gradually decreases from the storing drum 133 and is consumed so that the rear end detection sensor 139b no longer detects the yarn Y; therefore, the pulse motor 137 is re-driven to resume the winding process by the length-measuring/storing device 130.
- the yarn Y is wound on the storing drum 133 while advancing forward along the slightly narrowed diameter in a sliding manner on the taper shaped outer diameter portion so that the yarn is again stored over the entire length of the storing unit, with the leading-portion detection sensor 139a being allowed to detect the yarn Y.
- the speed at which the yarn Y is being stored by rotating the winding tube 132a is set at a speed higher than the knitting speed.
- This arrangement is made from the viewpoint of absorbing an error between the knitting speed and the storing speed and of taking the periods of time of yarn selection and yarn-joining into consideration; thus, by storing the yarn faster than the knitting speed, it becomes possible to continue the knitting operation even during the selection of a new yarn and yarn-j oining process after the yarn storage.
- Fig. 17 shows examples of knit fabrics; and Fig. 17(a) shows a knit fabric knitted by a flat knitting machine and Fig. 17 (b) shows a knit fabric knitted by a round knitting machine.
- a fabric basically knitted by yarn Y1 contains various types of color yarns, Y2, Y3 and Y4, that are knitted therein with predetermined lengths in a predetermined order, with a short pattern indicated by Y5 being arranged therein.
- Fig. 17(b) shows an arrangement in which a fabric knitted by a basic yarn Y6 contains a color yarn Y7 knitted therein with a predetermined length at predetermined positions.
- the present invention can be commonly applied to various knitting machines such as flat knitting machines and round knitting machines, and has an arrangement in which the yarn-length measuring/storing device 130, which is driven to rotate by a pulse motor or the line with the rotation angle being controlled, is allowed to wind the knitting yarn up while various color yarns are yarn-joined; therefore, it is possible to provide a knitting machine 1 which can knit even a short pattern using various color yarns as described in the present embodiment.
- At least one yarn is selected from a plurality of packages having different colors and a plurality of packages having different types of yarns, and the yarn is continuously knitted while being yarn-joined, and the yarn length of each of various types of color yarns with various yarn types is determined by taking a pattern after the knitting process into consideration; thus, it becomes possible to knit a desired pattern, to readily manufacture a fabric in accordance with each of various orders, and consequently to provide a knitting machine capable of responding to demands for various types of products in small amounts.
