The pair of push levers 42 and 43 in the second guide mechanism 36 is designed to be out of phase in the pivoting direction to be brought into contact with the color yarn to push the color yarn Ya in a slanted state to a horizontal state with respect to the yarn splicing apparatus.

The operating sequences of the yarn selection guide element 26 and the tracking yarn guide device 34 in the yarn type selection device 18 are indicated by numbers of the arrows [Y1] to [Y5] in the 5 to 7 displayed, and in 5 For example, the respective constituent elements in the traveling state of the leading yarn Yb to be joined are indicated by solid lines, and modes in which the yarn selecting guide element 26b in the arrow [Y1] direction in the yarn type selecting apparatus 18 is driven and the first guide mechanism 35 in the wake yarn guide device 34 in the arrow [Y2] direction, are indicated by hypothetical lines. In 6 a state is indicated by solid lines in which the yarn selection guide element 26a for the trailing yarn Ya selected to be yarn-bonded in the [Y3] direction, the vertical part Ya 'of the trailing yarn Ya being formed, and a state in which the first guide mechanism 35 in the arrow [Y4] direction, with the vertical part Ya 'of the trailing yarn Ya hooked, indicated by hypothetical lines. In 7 That is, a state before the operation of the trailing yarn pushing lever member in the arrow [Y5] direction to set the trailing yarn Ya to be joined in the yarn splicer is indicated by solid lines. According to these sequences, the advancing color yarn Yb and the trailing color yarn Ya to be joined with the color yarn Yb become in the yarn bonding apparatus 19 set in a state capable of yarn connection.

Next is the yarn splicer 19 in the yarn joining unit 13 placed adjacent to the yarn type selecting unit 12 is placed. In this invention, the yarn splicer cuts 19 once in an efficient manner the Vorlauffarbgarn Yb, in a storage drum 57 is stored later (at this stage, the above-mentioned color yarn Yb is located between the take-up yarn body 23 and the yarn supply package SPb in a connected state), and with the cut end of the leader color yarn Yb, the tail of the tail color yarn Ya is yarn-bonded; Consequently, the device is formed by at least one Garnschneidmechanismus and Garnverbindungsmechanis mechanism.

In relation to this yarn connecting device 19 can devices such. A fishing knot machine and a weaver knot machine forming knots are used; however, z. A pneumatic yarn joining apparatus relating to the previously filed patent of the same applicant as the present invention (for example, an apparatus disclosed in U.S.P. JP-A No. 61-16711 described) or a binding type yarn joining apparatus. The yarn joining apparatus used in the present invention is arranged substantially so that the leader yarn Yb stored in a storage drum 57 saved later is described (at this stage, the yarn Yb of course, between the Garnversorgungsgarnkörper SPb and the package P on the take-up side is continuous), and the tail yarn Ya, by the yarn type selection device 18 is selected, individually received and held, and in the respective held states, the leader yarn Yb and the tail yarn Ya are cut, and the cut portions of the respective yarns are combined with each other to be yarn-bonded by allowing them to be entangled Entangle state, or the cut parts of the respective yarns are combined and joined together by binding.

According to the 5 to 7 Illustrated embodiments is the yarn connecting device 19 is provided with two V-shaped guide plates GP1 and GP2, and each of the V-shaped guide plates has a first V-shaped guide groove G1 leading and receiving the lead yarn Yb and a second V-shaped guide groove G2 leading the trailing yarn Ya and receives. In the case of the knotter, a first knotter beak NB1 holding the supply Yb yarn and a second knotting beak NB2 holding the supply yarn Ya are placed between the above-mentioned V-shaped guide plates GP1 and GP2. According to this embodiment, the first said feed yarn Yb is guided and inserted along the first V-shaped guide groove G1 and held by the first knot beak NB1, and the yarn Ya is guided and inserted along the second V-shaped guide groove G2 and through the second knot beak NB2 held; consequently, a predetermined yarn knotting process is performed.

Next, the following description will discuss the structure of the yarn length measuring / storing unit that exists between the yarn joining unit 13 and the take-up unit 15 is placed. The yarn length measuring / storage unit is equipped with a yarn length measuring / storage device 20 which measures the yarn length of the selected yarn to be wound and temporarily stores the wound yarn. 4 FIG. 12 illustrates one embodiment that specifically describes the yarn length measuring / storage device 20 represents. The yarn length measuring / storage unit 20 according to this embodiment is with a stationary machine part 45 and an independent rotary drive source M1 attached to a suitable stationary structure (which is the stationary machine part 45 can be), and a rotary element 47 that by means of a power transmission mechanism 46 is connected by the rotational drive operation of the rotary drive source M1 in a force-transmitting manner, comprises a rotary shaft part 48 and a branch part 49 extending in a radial direction as it rotates the shaft portion 48 cuts, and in the rotary shaft part 48 and the branch part 49 includes a yarn introduction travel hole 50 , which allows yarn insertion and advancement, a rotary shaft.

The above-mentioned rotary element 47 is going through a warehouse 51 worn like a shaft, so that it is inside the stationary machine part 45 turns, and is with a compensation device 52 for the branch part 49 and an elongated shaft part 53 Mistake. A cylindrical yarn length measuring / storage element 55 is on this extended shaft part 53 through a warehouse 54 appropriate. For example, is a magnetic force connection device 56 between the yarn length measuring / storage element 55 and the stationary machine part 45 placed so that the yarn length measuring / storage element 55 by the magnetic force connection device 56 with the stationary machine part 45 is connected by a magnetic force to even during rotation of the rotary member 47 to be kept in a stationary state. Here is the yarn length measuring / storage element 55 with a storage drum unit 57 provided that slants in a way so that they are towards one end 55a becomes narrower, with a stopper flange 58 attached to the narrower extremity.

With respect to the yarn length measuring / storage element 55 in the yarn length measuring / storage device 20 are a first position sensor 59 and a second position sensor 60 used to detect the amount of coiled yarn wrapped around the storage drum unit 57 is wound, placed, and a yarn guide 61 for guiding the yarn coming from the storage drum unit 57 to pull is also mounted.

In the yarn length measuring / storage device 20 with the above-mentioned arrangement, during a pulling time of the yarn Y, if the branching part is allowed 49 which is on one end of the rotary element 47 is placed to the yarn length measuring / storage element 55 is rotated by the rotational drive operation of the independent rotary drive source M1, the yarn Y, that of the branch part 49 of the rotary element 47 is pulled, successively in the arrow a direction along a cone side of the storage drum unit 57 in the yarn length measuring / storage element 55 fed and temporarily stored before being wound around the take-up yarn body.

In said arrangement, the rotary drive source M1 z. B. formed by a stepping motor, wherein the circumferential length of the storage drum unit 57 provisionally established by a unit of mm; thus, based on the equation, a rotation of the stepping motor = circumference length (mm) of the storage drum unit 57 , the length of the selected trailing yarn is calculated based on the number of revolutions of the stepping motor or the number of pulses so that the length of the selected trailing yarn is measured within an error range of several millimeters. The above-mentioned rotary driving source M1 may be a stepping motor or a servomotor instead of the stepping motor.

With respect to the first and second position sensors 59 and 60 arranged to detect the amount of Y yarn that belongs to the storage drum unit 57 in the yarn length measuring / storage element 55 of the yarn length measuring / storage device 20 has been fed to be wound up, the first position sensor controls 59 a station 57b spaced by a distance α in the storage drum unit 57 from a yarn package start position 57a is separate, ie, a station used to detect a position of the yarn that has been stored in such a way so that there is no shortage of yarn on the storage drum unit 57 is caused while the next selected yarn is being connected, and to detect whether or not there is any yarn at the station, and outputs the resulting detection signal to the control unit 16 out. The first position sensor 59 Detects a state in which the yarn having a length corresponding to the axial direction distance α on the storage drum unit 57 remains as a yarn-free condition. The second position sensor 60 Detects if any yarn in a fully wound station 57c in the storage drum unit 57 is present or not and gives the resulting detection signal to the control unit 16 out.

The following description will discuss yarn joining and winding control processes in the above-mentioned apparatus. In the present invention, first, in addition to the order of the yarns to be wound, the types of yarns to be wound up and lengths of the types of yarns of the control unit 16 entered and set in her. In this case, the length of the selected yarn is automatically converted into a number of pulses to be output to the stepping motor M1 or set as a number of pulses. Since the circumferential length of the storage drum unit 57 has been previously known, the length of the yarn to be wound is set based on the number of pulses required for rotation of the stepping motor M1 and the circumferential length as a number of pulses. Therefore, the length of the yarn to be wound is set by a unit of mm.

In a normal winding operation, when the selected yarn is wrapped around the storage drum unit 57 has been wound around the length that has been determined, the stepping motor M1 by an instruction from the control unit 16 stopped while the next predetermined type of yarn is selected and bonded to the leader yarn. During the yarn joining operation, a motor M2 on the take-up unit 15 side continues to rotate, so that in the storage drum unit 57 stored yarn is wound by a package P. Upon completion of the yarn joining process, the stepping motor M1 is again driven and rotates by the number of pulses corresponding to the set length of the re-stored yarn. In this way, the yarns of the predetermined types and lengths are wound onto packages P.

Normally, the storage speed (rotational speed of the motor M1) is greater than the winding speed (rotational speed of the winding-use motor M2); however, when the yarn joining operations are frequently performed, the stored yarn decreases, sometimes causing the reduction position sensor to be caused 59 detected the yarn-free state. In this case, the winding-use motor M2 is temporarily stopped, and it is preferable that the yarn storage operation to the storage drum unit 57 carried out. When the yarn is around the storage drum unit 57 has been wound to allow the position sensor 59 again detects the Garnspeicherzustand, the winding-use motor M2 is again driven to rotate. Here, the winding use motor M2 can be driven to rotate at a reduced speed without stopping, so that the storage process can be performed while the winding process is continued.

In contrast, in the case where the set length of the selected yarn is long, since the yarn joining process is not performed frequently, the amount of on the storage drum increases 57 wound yarn, so that upon detection of Garnspeicherzustands by the position sensor 60 for detecting the maximum position of the motor M1 is stopped and the winding process is preferably carried out by rotation only of the winding-use motor M2. When the amount of yarn on the storage drum 57 decreases, so that allows the position sensor 60 to detect the maximum position, the yarn-free state, the motor M1 is driven again to the storage process of yarn on the storage drum 57 to resume. In this case, too, the speed of the winding-use motor M2 is increased without stopping the motor M1 to continue the rotation; consequently, the amount of on the storage drum 57 stored yarn can be reduced by the Winding speed is increased.

In the above-mentioned winding control, the detection signals indicating the yarn storage state or the yarn-free state are obtained by the first and second position sensors 59 and 60 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 (rotating speed of the winding-use motor M2) can be set to a low speed in the case where a type of yarn whose length is comparatively short is continuously fed, and The winding speed can be set to a high speed in the case where another type of yarn whose length is comparatively long is continuously supplied. Consequently, it becomes possible to perform an effective winding process without stopping / driving the motor.

The Yarn processing system of the present invention relates to a Yarn connection winding technique for different types of Yarns, wherein different types of yarns of a plurality of Species with z. B. different colors on Garnweise with, respectively desired Connected lengths be while they follow each other according to a pre-designed pattern selected so that the resulting yarn is wrapped in a package is, and this system is provided with a yarn type selection unit, between a yarn supply unit and a yarn joining unit is placed, and the yarn type selecting unit has a yarn type selecting device that select a trailing yarn on the yarn supply side to connected to a feed yarn on the Aufwickelgarnkörperseite on Garnweise to become; therefore, the yarn splicer and the work Yarn type picker so that the feed yarn is introduced into the yarn splicer, the feed yarn connected to the yarn type picker so is that the wake yarn by a Nachlaufgarnführungseinrichtung in the yarn splicer introduced to undergo a yarn bonding process. This arrangement make it possible, a yarn selection and To perform yarn joining process quickly, and also the need to eliminate the other device units while to stop the yarn joining processes; hence it becomes possible to be a superior one capital and effective functions from the point of view of an availability factor provide.

The following description will discuss a second embodiment in which the above-mentioned yarn processing unit 15 as a commodity pattern warping SW is made.

Next discussed with reference to the 2 to 9 the following description will describe a specific structural example of a yarn compound take-up winder for different types of yarns used in a commodity pattern warper according to the present invention. As in 9 As shown, the yarn compound take-up winder for different types of yarns to which the present invention is applied is basically a yarn supply unit 11 , a yarn type selecting unit 12 , a yarn joining unit 13 , a yarn length measuring / storage unit 14 and a take-up unit 15 provided, which are aligned in a line, with a control unit 16 is added.

The above-mentioned yarn supply unit 11 is with a yarn supply package creel 17 which properly arranges a plurality of types of yarn supply package groups, and arranged so that n kinds of yarn supply packages SPa, SPb, ... SPn including color yarn Ya having a color a, color yarn Yb having a color b, color yarn Yn with a color n are placed so that Garnzuführungsbe operations are performed without interfering with each other. The color yarn Ya, color yarn Yb, ..., color yarn Yn respectively supplied from the yarn supply packages SPa, SPb, ... SPn become the yarn type selecting apparatus, respectively 18 through a guide 21 and a pulling device (not shown) supplied.

The color yarn Ya, color yarn Yb, ..., color yarn Yn supplied from these color yarn groups are passed through a color type selecting apparatus 18 that in the color type selection unit 12 is placed, selected to achieve a pre-designed pattern, by a yarn splicer 19 that in the yarn connection unit 13 placed on yarn and measured in a yarn length and in a yarn length measuring / storage device 20 stored in the yarn length measuring / storage unit 14 is placed; consequently, these yarns are formed into a bonded yarn CY which is sequentially bonded in a predetermined order with a yarn-length determined on the basis of the pre-designed pattern, and this is further described in e.g. B. a Kettgarnbaum V z. B. as in 11 A formed by a winder WA, which includes a warping drum D, which in the take-up unit 15 is placed.

Here is the above-mentioned yarn type selecting unit 12 with a yarn type picker 18 which reserves the end portions of the color yarn Ya, color yarn Yb, ..., color yarn Yn supplied from the respective yarn supply packages SPa, SPb, ..., SPn, and supplies at least one specific color yarn to a travel station according to instructions from the control unit 16 ,

With respect to specific structures of the above-mentioned yarn type selecting apparatus 18 , Yarn connecting device 19 and yarn length measuring / storage device 20 these are the same as those by reference to the 2 to 7 are explained in detail.

According to another structural example of the present invention, a yarn length measuring device 70 be placed in the warping drum D, and the above-mentioned yarn connecting device 19 may be placed between the above-mentioned yarn supply package and the warper drum. In this case, the yarn length measuring device 70 provided with an independent rotary drive source M4 and comprises a rotary member 71 , which can be rotated by the rotary drive operation of the rotary drive source M4. A yarn insertion advancing hole through which the yarn is introduced and passed is in the rotary member 71 formed, so that of the rotary element 71 supplied yarn is wound on the above-mentioned warping drum D.

In the yarn length measuring device 70 with the above-mentioned arrangement, during a pulling time of the yarn Y, when the rotary member is allowed to move 71 by the rotary drive operation of the independent rotary drive source M4 rotates about the warper drum D, that of the rotary member 71 drawn yarn wound on the peripheral surface of the warping drum D. In this arrangement, the rotary drive source M4 z. B. formed by a stepping motor, wherein the circumferential length of the warping drum D is provisionally set by a unit of mm; consequently, based on the equation: a rotation of the stepping motor = circumferential length (mm) of the warping drum D, the length of the selected yarn can be calculated based on the number of revolutions of the stepping motor or the number of pulses so that the length of the selected yarn is within one Error range of a few millimeters is measured. The above-mentioned rotary drive source M4 may be a stepping motor or a servomotor instead of the stepping motor.

Regarding 9 The following description will discuss control operations of the pattern warper of the present invention. In the present invention, first, in addition to the order of the yarns to be woven, information related to a pattern fabric to be woven, such as, for example, woven fabric, is obtained. The types of yarns for respective commodity pattern patterns and lengths of the types of yarns, to the control unit 16 entered and set there. In this case, the length of the yarn selected in the order to be woven as the commodity pattern is automatically converted into a number of pulses to be output to the stepping motor M1 (or the stepping motor M4 in another embodiment). or set as a number of pulses. Since the circumferential length of the storage drum unit 57 has been previously known, the length of the yarn to be wound is set as a number of pulses on the basis of the number of pulses required for rotation of the stepping motor M1 and the circumferential length. Therefore, the length of the yarn to be wound is set by a unit of mm.

In a normal winding operation, when the selected yarn is wrapped around the storage drum unit 57 (or warping drum D) has been wound by the length which has been determined, the stepping motor M1 (or stepping motor M4) by an instruction from the control unit 16 stopped while the next predetermined type of yarn is selected and connected to the leader yarn. During this yarn joining operation, that becomes in the storage drum unit 57 stored yarn is wound on the warper drum D. When finished In accordance with the yarn joining process, the stepping motor M1 is again driven and rotates by the number of pulses corresponding to the set length of the re-stored yarn. In this way, the predetermined types and lengths of yarns are wound on the warper drum D.

Normally, in this yarn length measuring / storage apparatus, the storage speed (rotational speed of the motor M1) is larger than the winding speed of the warping drum D; however, when the yarn joining operations are frequently performed, the stored yarn decreases, sometimes causing the reduction position sensor to be caused 59 detected the yarn-free state. In this case, the winding operation to the warper drum D is temporarily stopped, and the yarn storage operation to the storage drum unit 57 is preferably carried out. When the yarn is around the storage drum unit 57 has been wound up to allow the position sensor 59 rediscovered the Garnspeicherzustand, the winding operation is resumed on the warping drum D.

On the contrary, in the case where the set length of the selected yarn is long, since the yarn joining process is not performed frequently, the amount of on the storage drum increases 57 wound yarn, so that upon detection of Garnspeicherzustands by the position sensor 60 for detecting the maximum position of the motor M1 is stopped and preferably the winding process is performed on the warping drum D. When the amount of yarn on the storage drum 57 decreased to allow the position sensor 60 to detect the maximum position, the yarn-free state, the motor M1 is driven again to the storage process of yarn on the storage drum 57 to resume. In this case, too, the winding speed on the warper drum D can be increased without stopping the motor M1; consequently, the amount of on the storage drum 57 stored yarn can be reduced.

The above-mentioned embodiment represents a case where, as in FIG 9 shown, a yarn supply unit 11 , a yarn selection unit 12 , a yarn joining unit 13 , a yarn length measuring / storage unit 14 and a warping drum D are connected and aligned directly in a row; however, a plurality of groups, each of which may be devices from the yarn supply unit 11 to the yarn length measuring / storage unit 14 are placed in relation to a single warping drum D, so that the yarn supply units can prepare different product pattern patterns of different types as a single warp beam.

Corresponding the commodity pattern warping machine according to the present Invention will be without a Kettgarnbaum for each of pattern samples has to be prepared, a warp yarn of a plurality of pattern samples prepared as a single Kettgarnbaum, and there may be a plurality of pattern patterns are woven continuously by the single warp yarn is used; therefore this procedure works effective, by having a preparation time to set up Kettgarnbäumen for the respective sample pattern is required, greatly reduced becomes.

Corresponding the commodity pattern warping machine The present invention, as a yarn splicer for different Types of yarns that a yarn joining process in a plurality of types of yarns with z. B. different colors with each desired lengths while the corresponding yarn according to a pre-designed pattern sequentially selected is mounted, and a yarn length measuring / storage device be, so the yarn length a desired one Yarn type is set freely, and a yarn selection and yarn joining process done quickly be, and possible is to eliminate the need for the other device units while the yarn joining operation to stop; consequently possible, superior To provide functions, that an excellent fortune under the aspect of an availability factor will be shown.

Regarding 13 a knitting machine according to the present invention will be explained. The knitting machine 101 consists of a knitting machine main body 102 and a yarn supply device 103 which is placed in it. The yarn supply device 103 Yarns Y1, Y2 and Y3, respectively, of yarn packages P1, P2, P3... pull the yarns on a slip-on gate 110 attached, allows this through a Zugaufbringelement 111 pass through and passes the yarns to the knitting machine main body 2 through a yarn splicer 112 , a yarn length measuring / storage device 130 and a second Zugaufbringelement 113 to.

The packages P1, P2, P3 ... are packages each having yarns of different colors and types, and continuously feed the yarns to the yarn length measuring / storage apparatus 130 to, with the yarns through the yarn splicer 112 be continuously connected to Garnweise. In addition, the types and number of packages needed to make a desired knitted fabric are at the creel 110 and not limited to three shown in the drawing, it may be mounted without limitation in the number six or twelve of them.

The yarn selection device 120 is with respective yarn guides 121 . 121b and 121c (please refer 15 ) attached to the respective packages P1, P2 and P3, and as will be described later, these guides are controlled to move toward a yarn guiding position (corresponding to FIG 121A in the drawing) used to guide the Y yarn to the yarn splicer 12 is used, and a leadership position (corresponding to 121B in the drawing) for guiding the yarn Y to a suction element 116 is used to move freely.

The yarn connecting device 112 performs cutting and bonding processes of the yarn Y, and that through the yarn selecting device 120 Selected yarn is directed towards the yarn splicer 112 through an in 14 shown leadership 126 guided and subjected to a Garnverbindungsprozess. In relation to the yarn connecting device 112 For example, a splicer that performs a yarn splicing process using a fluidized air flow may be used, or a knotter that performs a yarn knitting process may be used. With regard to whether the splicer or the knotter is used, a selection is made appropriately depending on the type of yarn to be used and a required yarn bonding mode.

With reference to the 14 and 15 The following description will discuss the yarn selector 120 in detail. In relation to the yarn guide 121 are each a yarn guide 121 for guiding the yarn Y1, a yarn guide 121b for guiding the yarn Y2, a yarn guide 121c , ... for guiding the yarn Y3, ... and so on, and a pivoting member 128 becomes a pivot point 128a as the center of a rotation through a cylinder 127 panned, leaving a rising pole 128b on the other end of the vibrating element 128 placed in contact with a rear guide plate 122B the yarn guide 121 comes to the yarn guide 121 to pivot the yarn Y to the yarn splicer 112 free to move (according to 121B ).

The yarn guide 121 has a projection part 122 up, and it allows them to turn around a rotation axis 122A turns freely. A rear guide plate 122B , which extends backwards, is at the projection part 122 attached, and a spring element 123 at the rear guide plate 122B attached, is used to guide the yarn 121 to press in the direction of a Garnführungsposition (corresponding to 121A in the figure) in which the yarn Y is the yarn bonding apparatus 112 to be led.

That on the intake 116 sucked Y yarn is between a Garnhaltewalze 117 and a Garnhalteplatte 118 trapped. The yarn holding roller 117 is a roller element, which on its peripheral surface with an elastic element, such. As urethane coated, and the Garnhalteplatte 118 is with the yarn holding roller 117 through a cylinder 119 contacted and separated from her.

When the yarn guide 121 is pivoted during a selection of the yarn, the Garnhalteplatte 118 from the yarn holding roller 117 separated so as to allow that the suction element 116 the yarn Y sucks. When the appropriate yarn is selected and the appropriate yarn guide 121 at 121A is positioned, the Garnhalteplatte 118 in contact with the yarn holding roller 117 through the cylinder 119 brought, so that the yarn Y, which is on the suction 116 sucked, is held.

A notched portion is in the rear end of the rear guide plate 122B formed to with an engaging element 124 to be engaged, and if the yarn guide 121 to the position (corresponding to 121B in the drawing) for guiding the yarn Y to the suction element 116 through the cylinder 127 by a rising pole 128b used, the cylinder brings 125 the engagement element 124 with the notched portion at the rear end of the rear guide plate 122B engaged so that the position of the yarn guide 121 at the position of 121B is secured in the drawing. The engagement element 124 is through the cylinder 125 driven to get around a pivot 124A as a turning center to turn freely.

With respect to a switching method of the yarn, the cylinder becomes first 127 slightly extended to the rear guide plate 122B raise them so that they are out of engagement with the engagement element 124 is released. Next is just the cylinder 125 driven in accordance with the type of yarn to be selected, so that the engagement element 124 is postponed; consequently, the engagement element becomes 124 set in such a condition that it is not in contact with the rear guide plate 122B regardless of the position of the same. After that, the cylinder becomes 127 retracted to the yarn guide 121 to put in such a position that only the engagement element 124 not with the rear guide plate 122B is engaged; consequently, the yarn guide becomes 121 according to the selected yarn type to a yarn guide station (corresponding to 121A in the drawing) used to guide the Y yarn to the yarn splicer 112 is used, and at the leading position accordingly 121B stopped.

The yarn that is made possible by the selected yarn guide 121 to run through, has an end that through the suction 116 and forms a yarn YA indicated by a broken line. This yarn YA will be directed towards the yarn splicer 112 through the leadership 126 guided, which is pivoted in the direction of the arrow when pulled, so that it is connected to the yarn Y on Garnweise that on the yarn length measuring / storage device 130 has been wound, and subjected to a winding process.

In this case can with regard to the types of yarns, not limited to one type, two types of yarns (eg yarns Y1 and Y2) are selected simultaneously and be connected to Garnweise.

Regarding 16 The following description will discuss the yarn length measuring / storage device 130 , If the yarn length measuring / storage device 130 is driven to start a winding process, the yarn Y is of a predetermined length in a storage drum 133 saved. A rotary shaft 132 with a yarn passage 132b located along the central axis inside a device main body 131 is formed, is for rotation by a stepper motor 137 driven (or a servomotor, which is capable of angular control). A pulley 134 at the rotary shaft 132 is attached, is for rotation by a pulley 136 and a drive belt 135 , the stepper motor 137 attached, driven, so that the rotary shaft 132 is rotated, and it allows for a winding tube 132a that of the rotary shaft 132 is branched off to the storage drum 133 swings.

If the winding tube 132a for rotation around the storage drum 133 is driven, the yarn Y, through the yarn passage 132b passes, which is formed in a manner to the winding tube 132a from the central axis of the rotary shaft 132 to penetrate, on the storage drum 133 wound, which is formed in a wedge shape whose diameter is made slightly narrower in the advancing direction of the yarn, and stored thereon. That of the winding tube 132a drawn Y yarn is about the outer diameter part of the wedge-shaped running part of the storage drum 133 so as to allow it to advance along the slightly narrower diameter while the wedge-shaped member slides. If the Y yarn with rotating winding tube 132a around the storage drum 133 is wound continuously, the above-mentioned yarn sliding function is continuously applied, the yarn Y is stored along the virtually entire length of the outer diameter part of the tapered part of the storage drum in a helically oriented state.

The control operation of the yarn length to be selected is controlled by controlling the rotation angle of the stepping motor 137 (or servomotor capable of angle control or the like) using a controller not shown. Therefore, the length control operation with a fine size (not more than 1 cm) is available. In cooperation with the rotation angle (corresponding to the yarn length determined by taking a pattern after the knitting process into account) of the stepping motor 137 which is rotated in accordance with a control program determined by taking an image pattern after the knitting process into consideration becomes the winding tube 132a rotated by a predetermined angle, so that the length of the yarn on the storage drum 133 is wound and stored on it, exactly to the yarn length is controlled to form the pattern after the knitting process. The presence of the on the storage drum 133 stored yarn Y is detected by a detection sensor, such as. A photoelectric sensor is detected, and in the present embodiment, a detection sensor 139a for the foremost part and a detection sensor 139b placed for the back part.

If after the start of the winding process of the yarn Y on the storage drum 133 the detection sensor 139a for the foremost part, the yarn Y is detected, the rotary drive process of the winding tube 132a temporarily stopped. In a state where the winding process of the yarn Y onto the storage drum 133 is stopped to set the storage process, when the operation is continued, the yarn from the storage drum 133 gradually and is consumed, leaving the detection detector 139b for the rear end, the yarn Y is no longer detected; therefore, the stepper motor becomes 137 re-powered to the winding process by the length measuring / storage device 130 to resume. When the winding process is resumed, the Y yarn becomes the storage drum 133 while advancing along the slightly narrowed diameter in a sliding manner on the outer cone-shaped diameter portion, so that the yarn is stored again over the entire length of the storage unit, thereby enabling the detection sensor 139a for the foremost part yarn Y is detected.

The speed at which the yarn Y by turning the winding tube 132a is set at a speed higher than the effective speed. This arrangement has been made from the viewpoint that an error between the kneading speed and the storage speed is absorbed and the time periods of yarn selection and yarn joining are taken into consideration; consequently, 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 joining process after the yarn storage.

17 represents examples of knitted fabrics; and 17 (a) represents an knitted fabric knitted by a flat knitting machine, and 17 (b) represents a knitted fabric knitted by a circular knitting machine. In 17 (a) contains a fabric which is substantially knitted by the yarn Y1, various types of color yarns Y2, Y3 and Y4 knitted therein with predetermined lengths in a predetermined order, a short pattern indicated by Y5 is arranged therein. 17 (b) illustrates an arrangement in which a fabric knitted by a base yarn Y6 contains a colored yarn Y7 knitted therein at a predetermined length at predetermined positions.

As described above, the present invention can usually be applied to various knitting machines, such as knitting machines. As flat knitting machines and circular knitting machines, are applied and has an arrangement in which it is possible that the yarn length measuring / storage device 130 which is driven for rotation by a stepping motor, or the line at the controlled angle of rotation winds the knitting yarn while various color yarns are yarn-bonded; therefore it is possible to have a knitting machine 1 which can itself act as a short pattern using different color yarns as described in the present embodiment.
