Description

  The present invention relates to an automatic winder for winding a yarn unwound from a yarn supplying bobbin to form a package, and a yarn winding method for unwinding and winding a yarn from a yarn supplying bobbin using the automatic winder.

  In the bobbin conveying system described in Patent Document 1, in the bobbin supply unit, the bobbin supplying unit can supply the bobbin to the take-up unit, such as hanging the yarn end of the bobbin supplied from the ring spinning machine into the core tube. Prepare to. And the bobbin prepared in the state which can be supplied to a winding unit is supplied to the several winding unit of an automatic winder. The winding unit winds the yarn unwound from the supplied bobbin to form a package. Moreover, in patent document 1, the bobbin discharged | emitted from the winding unit is returned to a bobbin supply apparatus. Of the bobbins returned to the bobbin feeder, bobbins that have been unwound normally and have almost no remaining yarn are removed by the bobbin stripper, which is a residual yarn processing device, and then sent to the ring spinning machine. Returned. On the other hand, if the bobbin has been discharged from the winding unit due to a misfeed or a yarn joining failure, the remaining yarn is returned to the spout device without being removed.

JP 2003-104628 A

  Here, in Patent Document 1, as described above, the bobbin discharged from the winding unit due to a misfeed or a yarn joining failure is supplied to the winding unit again. However, since the bobbin discharged from the winding unit due to the yarn joining failure usually has a smaller amount of yarn than the initial state, in the spouting device, the bobbin yarn wound portion and the core tube There is a possibility that the yarn end hung in the core tube is dropped from the core tube while being transported toward the winding unit because the distance from the tip is large. In this case, in the winding unit, the bobbin is discharged due to a misfeed.

  Further, the bobbin discharged from the winding unit due to the yarn joining failure may be a bobbin in which yarn joining has been performed many times due to poor yarn quality. In this case, even if the bobbin is supplied to the winding unit again, the bobbin is likely to be discharged from the winding unit due to the yarn joining failure.

  From these facts, when the bobbin discharged from the winding unit due to misfeeding or yarn joining failure is supplied again to the winding unit, the production efficiency of the package in the automatic winder may be reduced. .

  Here, unlike Patent Document 1, the bobbin discharged from the winding unit due to a misfeed or a yarn splicing failure is also removed with a bobbin stripper as in the case of the bobbin in which the yarn is normally unwound. It is also possible to return to the ring spinning machine. However, in this case, the amount of yarn that is removed by the bobbin stripper and discarded is increased.

  An object of the present invention is to provide an automatic winder and a yarn winding method that can reduce the production efficiency of a package and reduce the amount of yarn discarded as much as possible.

  An automatic winder according to the present invention includes a plurality of tray-type winding units that are arranged in the arrangement direction and wind up yarns of a yarn feeding bobbin placed on a tray to form a package, and a tray conveying device that conveys the tray. And a magazine device that is arranged in the arrangement direction together with the plurality of tray-type winding units and stores the yarn supply bobbins, and forms a package by winding the yarns of the yarn supply bobbins supplied from the magazine device And at least one magazine type winding unit.

  For example, when the yarn is not unwound normally in the tray type take-up unit (when yarn breakage due to tension frequently occurs, when yarn joining fails, etc.), the yarn feeding bobbin with the yarn remaining in the tray Discharged from the take-up unit. On the other hand, even if the yarn supply bobbin that has been discharged from the tray type winding unit due to poor winding and the yarn remains is supplied again to the tray type winding unit, There is a high possibility that the so-called lead-out process for making it possible to catch the yarn end of the yarn feeding bobbin before the feeding is not normally performed. For this reason, if the yarn feeding bobbin with the yarn remaining is supplied again to the tray type winding unit, the production efficiency of the package in the automatic winder may be reduced. In the present invention, apart from the plurality of tray-type winding units, at least one magazine-type winding unit is provided. Therefore, for example, in such a case, the operator can set the yarn supply bobbin with the yarn remaining in the magazine device, and can unwind and wind the yarn from the yarn supply bobbin in the magazine type winding unit. Thereby, the fall of the production efficiency of the package in an automatic winder can be prevented. In addition, the amount of yarn discarded can be reduced.

In the present invention, since the number of magazine type winding units is one tenth or less of the number of tray type winding units, the number of tray type winding units can be increased. As a result, most of the yarn feeding bobbins that have been successfully unwound and that have been normally unwound can be automatically and efficiently wound in a number of tray-type winding units. On the other hand, yarn supply bobbins for which the spout processing has failed or yarn supply bobbins whose yarn has not been unwound normally can be wound up in a small number of magazine-type winding units. The amount can be reduced.

The tray supply / discharge portion 61 is disposed below the panel member 65. The tray supply / discharge unit 61 first draws the tray 7 conveyed from the supply path 21 a of the tray conveyance device 5 into the tray passage 66. Further, the tray 7 drawn to the holding position A (the hatched tray position in FIG. 1) located substantially at the center of the tray passage 66 is held while the yarn Y from the yarn supplying bobbin 8 is unwound. Further, the tray 7 on which the yarn feeding bobbin 8 after the unwinding of the yarn Y is placed is discharged from the tray path 66 to the return path 21b.

  The reading / writing device 62 is disposed above the panel member 65. The reading / writing device 62 reads and writes data with the IC tag 45 of the tray 7 held by the tray supply / discharge unit 61.

  The unwinding assisting device 63 has a movable cylinder 63 a that covers the upper end portion of the yarn feeding bobbin 8. Then, as the unwinding of the yarn Y progresses, the movable cylinder 63a is lowered to restrict the bulge (balloon) of the yarn Y being unwound, thereby stabilizing the unwinding tension. The movable cylinder 63a can be moved up and down by a motor (not shown).

  The winding unit 53 includes a cradle 71 having a pair of cradle arms that rotatably and detachably supports the winding tube 70, and the surface of the winding tube 70 supported by the cradle 71 or the winding tube 70. A traverse drum 72 that can contact the surface of the formed package P is provided. The winding unit 53 rotates the traverse drum 72 with a motor (not shown) in a state where the traverse drum 72 is in contact with the winding tube 70 (or the surface of the package P), thereby traversing the yarn Y. The package P is formed on the outer periphery of the winding tube 70 by rotating the winding tube 70 while swinging.

  The yarn processing unit 52 includes a yarn feeler 81, a tension applying device 82, a yarn joining device 83, a yarn clearer 84, and a waxing device 85 in order from the lower side.

  The yarn feeler 81 detects the presence or absence of the traveling yarn Y between the unwinding assisting device 63 and the tension applying device 82. The tension applying device 82 is for applying a predetermined tension to the traveling yarn Y. As the tension applying device 82, for example, a gate type device having a fixed comb tooth and a movable comb tooth arranged to be movable with respect to the fixed comb tooth can be used.

  The yarn joining device 83 is used when the yarn clearer 84 detects a yarn defect and cuts the yarn Y, when a yarn breakage due to tension occurs during unwinding of the yarn from the yarn feeding bobbin 8, or when the yarn feeding bobbin 8 For example, when a new yarn supplying bobbin 8 is supplied after the remaining yarn is lost, the yarn on the yarn supplying side (lower yarn) and the yarn on the winding side (upper yarn) are spliced. As the yarn joining device 83, for example, an untwisting nozzle that untwists each of the upper yarn end and the lower yarn end, and a twisting device that twists the untwisted yarn ends by causing a swirling air flow to act on them. A so-called air splicer having a nozzle can be used. Although not shown, the yarn joining device 83 includes a yarn introduction lever for introducing the yarn Y, a cutter for cutting the yarn Y, a clamp for gripping the introduced yarn Y, and the like. Yes. Further, the yarn joining device 83 is provided with a counter 83a for counting the number of times of yarn joining for the yarn supplying bobbin 8.

  The yarn clearer 84 is for detecting a yarn defect such as a slab and the presence or absence of the yarn Y, and is provided with a cutter (not shown) for cutting the yarn when detecting the yarn defect. The waxing device 85 is for applying wax to the yarn Y.

  A lower thread catching guide member 86 and an upper thread catching guide member 87 are provided below and above the yarn joining device 83, respectively.

  The lower thread catching guide member 86 is configured in a pipe shape, and can be rotated up and down around a shaft 86a by a motor (not shown), and a suction port 86b is provided at the tip thereof. ing. Further, a negative pressure source 88 is connected to the lower thread catching guide member 86, and the thread end can be caught by sucking air from the suction port 86b at the tip. In addition, a shutter 90 that opens and closes between the lower thread catching guide member 86 and the negative pressure source 88 is provided between the lower thread catching guide member 86 and the negative pressure source 88. When performing yarn joining in the yarn joining device 83, the lower yarn catching guide member 86 rotates about the shaft 86a to a lower position, and catches the lower yarn at this position. Then, the lower thread is guided to the yarn joining device 83 by rotating to the upper position around the shaft 86a while capturing the lower thread.

  The upper thread catching guide member 87 is formed in a pipe shape, and can be rotated up and down around a shaft 87a by a motor (not shown), and a mouse 87b is provided at the tip thereof. . Further, a negative pressure source 89 is connected to the upper thread catching guide member 87, and the thread end can be caught by sucking air from the mouse 87b at the tip. A shutter 91 that opens and closes between the upper thread catching guide member 87 and the negative pressure source 89 is provided between the upper thread catching guide member 87 and the negative pressure source 89. When the yarn joining device 83 performs yarn joining in the yarn joining device 83, the upper yarn catching guide member 87 rotates to the upper position around the shaft 87a, and catches the upper yarn at this position. Then, the upper thread is guided to the yarn joining device 83 by rotating to the lower position around the shaft 87a while capturing the upper thread.

  Further, in the tray type winding unit 3, for example, when the quality of the yarn of the yarn feeding bobbin 8 is poor, the unwound yarn Y is frequently cut by tension, and yarn joining may be performed many times. Therefore, when the number of times of yarn joining counted by the counter 83a is a predetermined number or more (for example, 3 times or more), the tray 7 (yarn feeding bobbin 8) is placed in the return path 21b without performing yarn joining. Let it drain. At this time, the reading / writing device 62 writes information indicating that the yarn supplying bobbin 8 is a defective bobbin with poor quality on the IC tag 45.

  As described above, when yarn breakage due to tension frequently occurs in the yarn supplying bobbin 8, the yarn Y is not normally unwound from the yarn supplying bobbin 8. In the present embodiment, when the yarn joining count counted by the counter 83a is equal to or greater than a predetermined number, it is determined that the yarn supplying bobbin 8 is a defective bobbin in which yarn breakage frequently occurs due to tension. . That is, in the present embodiment, the counter 83a that counts the number of times of yarn joining corresponds to the unwinding failure detecting means according to the present invention.

  Further, when the yarn Y of the yarn supplying bobbin 8 runs out and a new yarn supplying bobbin 8 is supplied, the lower yarn catching guide member 86 sucks the yarn end of the newly supplied yarn supplying bobbin 8 as the lower yarn. Will be captured. At this time, as described above, if the yarn end of the yarn feeding bobbin 8 hangs down inside the core tube 8a, the yarn end of the yarn feeding bobbin 8 can be caught by the lower yarn catching guide member 86. 7, the yarn end of the yarn supplying bobbin 8 may fall from the core tube 8a due to vibration or air flow. Even in yarn joinings other than those described above, yarn joining fails due to factors such as failure of upper yarn catching by the upper yarn catching guide member 87 and failure of catching lower yarn by the lower yarn catching guide member 86. Sometimes. Therefore, in this embodiment, when the yarn joining fails, the yarn joining operation is repeatedly executed, and when the yarn joining is not successful even after repeating the yarn joining operation a predetermined number of times (for example, three times), the return path 21b. The tray 7 (yarn feeding bobbin 8) is discharged.

  Further, when the yarn Y of the yarn supplying bobbin 8 runs out and a new yarn supplying bobbin 8 is supplied, the tray 7 on which the yarn supplying bobbin 8 from which the yarn Y has been unwound until then is placed on the return path. It is discharged to 21b.

  Each of the unit control units 54 is a CPU (Central Processing Unit) that is an arithmetic processing unit, a ROM (Read-Only Memory) in which a program executed by the CPU and data used in the program are stored, and data at the time of program execution A RAM (Random Access Memory) for temporary storage, an input / output interface for inputting / outputting data to / from the outside, and the like are configured to be communicably connected to the machine control device 10 of the automatic winder 1.

(Magazine type winding unit)
Next, the magazine type winding unit 4 will be described. As shown in FIG. 7, the magazine type winding unit 4 is obtained by replacing the tray type yarn feeding unit 51 of the tray type winding unit 3 with a magazine type yarn feeding unit 100.

  The magazine type yarn supplying unit 100 includes a magazine device 101, a guide chute 102, a bobbin support unit 103, and a yarn shifting lever 104.

  The magazine device 101 is formed with a plurality of bobbin accommodation holes 101a that are arranged in the circumferential direction and each accommodate the yarn feeding bobbin 8. Here, in the present embodiment, the operator collects the yarn feeding bobbin 8 placed on the tray 7 stored in the branch collecting path 23 and sets it in the bobbin accommodating hole 101a as will be described later.

  Further, on the lower side of the magazine device 101, a bobbin receiving plate 106 for receiving the plurality of yarn feeding bobbins 8 respectively accommodated in the plurality of bobbin accommodating holes 101a is provided. The bobbin receiving plate 106 is formed with a notch 106a.

  The magazine device 101 can be rotated around the rotation shaft 101b by a motor (not shown). When a certain bobbin accommodation hole 101a comes above the notch 106a, the bobbin accommodation hole 101a is provided. The yarn feeding bobbin 8 housed in is dropped onto the guide chute 102 through the notch 106a. Further, the magazine device 101 is provided with a yarn end holding portion 105. The yarn end holding unit 105 sucks and holds the yarn end of the yarn Y of the yarn supplying bobbin 8 accommodated in the magazine device 101. Here, in the present embodiment, before the yarn supplying bobbin 8 is accommodated in the bobbin accommodating hole 101a, the operator captures the yarn end of the yarn supplying bobbin 8 and brings it close to the yarn end holding portion 105, thereby providing the yarn supplying bobbin. The yarn end holding portion 105 is caused to suck the yarn end 8.

  The guide chute 102 guides the yarn feeding bobbin 8 that has dropped from the magazine device 101 to the bobbin support portion 103. The bobbin support portion 103 is inserted into the lower end portion of the core tube 8 a of the yarn feeding bobbin 8 to hold the yarn feeding bobbin 8 and the yarn feeding bobbin 8 held by the peg 108 to the bobbin supporting portion 103. And a jump plate 109 (the “bobbin discharging device” of the present invention) that discharges to the outside.

  The peg 108 can be swung back and forth by a motor (not shown), and when the yarn feeding bobbin 8 is supplied, the peg 108 is inclined to the front side so that the tip portion faces the guide chute 102 side, When the yarn Y is wound, the posture is upright.

  When the yarn feeding bobbin 8 is held in an upright state by the pegs 108, the spring plate 109 stands by in a horizontal state shown in FIG. At this time, the lower end of the yarn feeding bobbin 8 is in contact with the spring plate 109. The yarn feeding bobbin 8 is discharged by rotating the spring plate 109 forward from this state and causing the yarn feeding bobbin 8 placed thereon to jump forward. The jump plate 109 is driven by the same motor as the peg 108, for example. Further, a bobbin recovery box 110 (the “bobbin recovery part” of the present invention) is provided in front of the magazine type winding unit 4. The bobbin recovery box 110 is open at the upper end, and the yarn feeding bobbin 8 that has been bounced off falls into the bobbin recovery box 110.

  The yarn shifting lever 104 is disposed between the magazine device 101 and the guide chute 102, and can be rotated around a rotation shaft 104a extending in the vertical direction by a motor (not shown). .

  Here, in the magazine type winding unit 4, when the yarn supplying bobbin 8 is replaced, after the yarn supplying bobbin 8 is supplied from the magazine device 101 to the bobbin support portion 103, as shown by a one-dot chain line in FIG. In a state where the catching guide member 86 is rotated to the front position, the yarn gathering lever 104 is rotated rearward. Then, the yarn Y between the magazine device 101 (yarn end holding portion 105) and the peg 108 is guided to the vicinity of the suction port 86b of the lower yarn catching guide member 86 by the yarn shifting lever 104. As a result, the yarn Y is sucked from the suction port 86 b and is guided to the yarn joining device 83 by the lower yarn catching guide member 86.

(Machine control device)
As shown in FIG. 2, the machine control device 10 includes a control unit 34 of the tray transport device 5, a unit control unit 54 of the plurality of tray type winding units 3, and a unit control unit 54 of the magazine type winding unit 4. Are connected so as to be able to communicate with each other, and respectively control the operations of the tray transport device 5, the plurality of tray-type winding units 3, and the two magazine-type winding units 4. As shown in FIGS. 2 and 3, the machine control device 10 includes an input unit 10a, a display unit 10b, and a lamp 10c. The input unit 10 a is configured to be able to input various conditions necessary for controlling each device of the automatic winder 1. The display unit 10b can display the operation status of each device of the automatic winder 1 or a display related to an abnormality of each device. When any abnormality occurs in each device of the automatic winder 1, the lamp 10c is lit to notify the operator of the occurrence of the abnormality.

(Determination of the destination of the yarn feeding bobbin discharged to the return path)
Next, a procedure for determining the conveyance destination of the tray 7 (yarn feeding bobbin 8) discharged from the tray type winding unit 3 to the return path 21b will be described. As shown in FIG. 8, the tray 7 discharged to the return path 21b first reads information on the quality of the bobbin from the IC tag 45 when passing through the reading device 14 (S101). If the yarn feeding bobbin 8 placed on the tray 7 is a defective bobbin (S102: YES), the tray 7 is conveyed toward the branch collection path 23 (S103).

  The tray 7 conveyed to the branch recovery path 23 is stored on the branch recovery path 23. Then, the yarn feeding bobbin 8 placed on the tray 7 stored in the branch collection path 23 is collected by the operator. The collected yarn supplying bobbin 8 is set in the bobbin accommodating hole 101a of the magazine device 101 of the magazine type winding unit 4. An empty yarn supply bobbin 8 is placed on the tray 7 from which the yarn supply bobbin 8 has been collected by the operator. That is, in the present embodiment, the tray 7 conveyed to the branch collection path 23 is loaded until the yarn feeding bobbin 8 is completely collected (the yarn feeding bobbin 8 is collected, and an empty yarn feeding bobbin 8 is placed instead. (S104: NO), it waits in the branch recovery path 23. When the collection of the yarn feeding bobbin 8 is completed (S104: YES), the yarn feeding bobbin 8 is returned from the branch collection path 23 to the return path 21b and conveyed toward the ring spinning machine 2 (S105).

  On the other hand, when the yarn supplying bobbin 8 is not a defective bobbin (S102: NO), the tray 7 is conveyed downstream of the return path 21b, and whether or not the yarn Y remains on the yarn supplying bobbin 8 by the remaining yarn sensor 15 or not. Is determined (S106). When the yarn Y does not remain on the yarn feeding bobbin 8 (S106: NO), the tray 7 is conveyed toward the ring spinning machine 2 (S105). When the yarn Y remains on the yarn feeding bobbin 8 (S106: YES), the yarn Y is conveyed toward the first bypass path 22a (S107).

  Based on the detection result of the remaining yarn sensor 16, the tray 7 conveyed to the first bypass path 22a determines whether or not the remaining amount of the yarn Y in the yarn supplying bobbin 8 is equal to or more than the above upper limit amount (S108). ). When the remaining amount of the yarn Y in the yarn supplying bobbin 8 is equal to or larger than the predetermined amount (S108: YES), the outlet device 12 performs the outlet processing without removing the residual yarn by the bobbin stripper 13 (S109). . Then, when the extraction process is successful (S110: YES), the tray 7 is supplied to the tray type winding unit 3 (S111). If the dispensing process has failed (S110: NO), the tray 7 is transported toward the second bypass path 22b (S112).

  The tray 7 conveyed to the second bypass path 22b in S112 is stored in the second bypass path 22b. The yarn feeding bobbin 8 placed on the tray 7 stored in the second bypass path 22b is collected by the operator. The collected yarn supplying bobbin 8 is set in the bobbin accommodating hole 101a of the magazine device 101 of the magazine type winding unit 4. An empty yarn supply bobbin 8 is placed on the tray 7 from which the yarn supply bobbin 8 has been collected. That is, in the present embodiment, the tray 7 conveyed to the second bypass path 22b in S112 waits on the second bypass path 22b until the collection of the yarn feeding bobbin 8 is completed (S113: NO). And when collection | recovery of the yarn feeding bobbin 8 is completed (S113: YES), it returns to the return path | route 21b from the 2nd bypass path | route 22b (returns to S106). Note that the tray 7 returned to the return path 21b is confirmed to have no yarn Y remaining on the yarn supplying bobbin 8 (S106: YES), and is conveyed toward the ring spinning machine 2 (S105).

  On the other hand, if the remaining amount of yarn in the yarn supplying bobbin 8 is less than the predetermined amount (S108: NO), the remaining yarn on the yarn supplying bobbin 8 is removed in the bobbin stripper 13 (S114). Thereafter, the tray 7 is conveyed to the second bypass path 22b through the supply path 21a (S115). At this time, the tray 7 passes through the spouting device 12, but since the yarn Y does not remain in the yarn feeding bobbin 8, the spouting processing by the spouting device 12 is not performed. The tray 7 conveyed to the second bypass path 22b in S115 is returned to the return path 21b (returns to S106). Note that the tray 7 returned to the return path 21b is confirmed to have no yarn Y remaining on the yarn supplying bobbin 8 (S106: YES), and is conveyed toward the ring spinning machine 2 (S105). Here, as described above, when the yarn supplying bobbin 8 for which the spouting process has failed is stored in the second bypass path 22b, the empty yarn supplying bobbin from which the remaining yarn of the yarn supplying bobbin 8 has been removed by the bobbin stripper 13 is stored. This obstructs the return of the tray 7 on which the 8 is placed to the return path 21b. For this reason, when the yarn feeding bobbin 8 for which the spouting process has failed in S112 is conveyed to the second bypass path 22b, it is preferable to notify the operator to encourage the collection of the yarn feeding bobbin 8 for which the spouting process has failed.

  According to the embodiment described above, the yarn feeding bobbin 8 (defective bobbin) in which the yarn breakage due to the tension has occurred many times in the tray type winding unit 3 is returned from the first bypass path 22a to the supply path 21a, Even if the squeezing process is performed by the squeezing device 12 and the tray type take-up unit 3 is supplied again, there is a high possibility that the yarn breakage due to the tension occurs many times. As a result, the production efficiency of the package P in the tray type winding unit 3 is deteriorated. On the other hand, when the remaining amount of the yarn Y in the yarn supplying bobbin 8 is large, if the remaining yarn is removed by the bobbin stripper 13, the amount of waste of the yarn Y increases.

  Further, as can be seen from a comparison between FIG. 5 and FIG. 9, when the remaining amount of the yarn Y of the yarn feeding bobbin 8 discharged from the tray type winding unit 3 is not so large (for example, less than half of the full winding) The amount of remaining yarn in the yarn supplying bobbin 8 is larger (for example, more than half the amount when fully wound), the core tube 8a of the yarn supplying bobbin 8 is more The distance between the portion around which the yarn Y is wound and the upper end where the yarn end is hung is increased. Therefore, when the remaining amount of the yarn Y of the yarn supplying bobbin 8 discharged from the tray type winding unit 3 is not so much, the outlet processing by the outlet device 12 tends to fail. There is also a yarn feeding bobbin 8 in which the spouting by the spouting device 12 is likely to fail even when the remaining amount of the yarn Y is large. At this time, it is conceivable to remove the yarn Y of the yarn feeding bobbin 8 for which the spout processing has failed with the bobbin stripper 13, but in this case, the amount of waste of the yarn Y increases.

  Therefore, in the present embodiment, when the yarn feeding bobbin 8 is a defective bobbin (S102: YES), the tray 7 is conveyed to the branch collection path 23 (S103). Then, the yarn feeding bobbin 8 placed on the tray 7 stored in the branch collection path 23 is collected. Further, in the present embodiment, when the dispensing process fails (S110: NO), the tray 7 is transported to the second bypass path 22b (S112). Then, the yarn feeding bobbin 8 placed on the tray 7 stored in the second bypass path 22b is collected. Then, in the magazine type winding unit 4, the package Y is formed by unwinding the yarn Y from the collected yarn supplying bobbin 8. Thereby, the fall of the production efficiency of the package P in the tray type winding unit 3 can be prevented, and the waste amount of the yarn Y can be reduced.

  In the present embodiment, a bobbin collection box 110 is provided on the front side of the two magazine type winding units 4 in which the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 falls. In contrast, in the present embodiment, two magazine type winding units 4 and a bobbin preparation device 9 are arranged so as to sandwich a plurality of tray type winding units 3 in the left-right direction. The return path 21b extending in the left-right direction across the plurality of tray-type winding units 3 is not arranged in the range where the two magazine-type winding units 4 are arranged. Thereby, the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 does not interfere with the yarn feeding bobbin 8 placed on the tray 7 conveyed through the return path 21b.

  In the above-described embodiment, the plurality of tray-type winding units 3 and the two magazine-type winding units 4 are arranged in the left-right direction by being attached to the common frame 20 extending in the left-right direction. . Therefore, the degree of freedom of arrangement of the plurality of tray type winding units 3 and the two magazine type winding units 4 is increased. Thus, when installing the plurality of tray-type winding units 3 and the two magazine-type winding units 4, the two magazine-type winding units 4 can be easily attached to the plurality of magazine-type winding units 4 as in the present embodiment. It can be arranged on the left side of the tray type winding unit 3, or two magazine type winding units 4 can be placed on the right side of the plurality of tray type winding units 3 as in Modification 2 (see FIG. 11) described later. It can also be arranged.

  The total number of tray type winding units 3 and the number of magazine type winding units 4 is determined by the size of the space in which the automatic winder 1 is arranged. On the other hand, among the yarn feeding bobbins 8 in which the yarn Y is unwound in the automatic winder 1, the number of yarn feeding bobbins 8 in which the yarn Y is unwound in the magazine type winding unit 4 is usually the tray type winding unit. 3 is very small (for example, 10% or less) compared with the number of yarn feeding bobbins 8 from which the yarn Y is unwound. Therefore, even if the number of magazine type winding units 4 is one tenth or less of the number of tray type winding units 3, the yarn feeding bobbin 8 conveyed to the branch collecting path 23 is sufficiently threaded. The package P can be formed by solving Y. And if the number of magazine type winding units 4 is made one tenth or less of the number of tray type winding units 3, the number of tray type winding units 3 can be increased accordingly, The production efficiency of the package P in the tray type winding unit 3 can be increased.

  Further, in the magazine type winding unit 4 of the present embodiment, the package P is formed by winding the yarn Y unwound from the yarn supplying bobbin 8 having a small remaining yarn amount. Therefore, the number of yarn feeding bobbins 8 used for forming one package P is larger in the package P formed by the magazine type winding unit 4 than in the package P formed by the tray type winding unit 3. The number of split yarns is increased. As a result, a quality difference may occur between the package P formed by the tray type winding unit 3 and the package P formed by the magazine type winding unit 4. On the other hand, in this embodiment, the doffing device 6 doffs only the package P formed by the tray type winding unit 3 and doffs the package P formed by the magazine type winding unit 4. do not do. Thereby, it can prevent that the package P from which quality differs is mixed. Here, the package P formed by the magazine type winding unit 4 is manually doffed by the operator, which is a burden on the operator. However, the number of packages P formed by the magazine type winding unit 4 is usually smaller than the number of packages P formed by the tray type winding unit 3. Therefore, contrary to the present embodiment, only the package P formed by the magazine type winding unit 4 is doffed by the doffing device 6 and the package P formed by the tray type winding unit 3 is operated by the operator. Compared with the case of manually doffing, the burden on the operator is small.

  In the present embodiment, since two magazine type winding units 4 are provided in addition to the plurality of tray type winding units 3, for example, for one defective bobbin, one magazine type winding unit 4 is used for yarn. For the yarn feeding bobbin 8 that has unwound Y and the spout process has failed, the other magazine-type winding unit 4 can be used to unwind the yarn Y. It is.

  In the above-described embodiment, since the magazine type winding unit 4 is provided separately from the plurality of tray type winding units 3, for example, the formation of the package P is continued in the plurality of tray type winding units 3. In the magazine type winding unit 4, by winding the yarn Y unwound from the yarn feeding bobbin 8 of a yarn type different from that wound by the tray type winding unit 3, the package P is formed, It is also possible to perform a winding test.

  Next, modified examples in which various changes are made to the present embodiment will be described.

  In the above-described embodiment, the bobbin recovery box 110 is provided in front of the two magazine type winding units 4, but the present invention is not limited to this. In the first modification, as shown in FIG. 10, the magazine-type winding unit 4 extends in front of the two magazine-type winding units 4 in the left-right direction across the two magazine-type winding units 4. A bobbin recovery conveyor 201 is provided which extends to the left side (the side opposite to the plurality of tray-type winding units 3) from the arrangement range. A bobbin recovery box 110 is provided on the left side of the bobbin recovery conveyor 201.

  In this case, the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 falls on the bobbin collecting conveyor 201 and is conveyed to the bobbin collecting box 110 by the bobbin collecting conveyor 201. Also in this case, similarly to the above-described embodiment, the two magazine type winding units 4 and the bobbin preparation device 9 are arranged so as to sandwich the plurality of tray type winding units 3 in the left-right direction. Yes. Further, in the left-right direction, the return path 21b is not arranged in a range where the two magazine type winding units 4 are arranged, and the bobbin collection conveyor 201 is arranged with a plurality of tray type winding units 3. It is not placed in the range. Therefore, the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 does not interfere with the yarn feeding bobbin 8 placed on the tray 7 conveyed through the return path 21b.

  In the above-described embodiment, the two magazine-type winding units 4 and the bobbin preparation device 9 are arranged so as to sandwich the plurality of tray-type winding units 3 in the left-right direction. Not limited. In the second modification, as shown in FIG. 11, two magazine type winding units 4 are arranged between the plurality of tray type winding units 3 and the bobbin preparation device 9 in the left-right direction. That is, both the two magazine type winding units 4 and the bobbin preparation device 9 are arranged on the right side (same side) of the plurality of tray type winding units 3 in the left-right direction. Further, in the second modification, upstream sensors for detecting the trays 7 at the portions of the return path 21b located on both sides of the range where the two magazine type winding units 4 are located in the left-right direction. 211a and a downstream sensor 211b are provided. In the second modification, the upstream sensor 211a and the downstream sensor 211b correspond to the tray detection unit according to the present invention.

  Further, in the second modification, a tray that exists in a portion of the return path 21b located within a range where the two magazine type winding units 4 are arranged in the RAM of the unit control unit 54 of the magazine type winding unit 4 or the like. The number M of 7 is stored. Then, as shown in FIG. 12 (a), when the automatic winder 1 is powered on, the unit controller 54 of the magazine type winding unit 4 uses the number M of trays 7 stored in the RAM or the like. Is reset to 0 (S201).

  When the upstream side sensor 211a detects the tray 7 (S202: YES), the unit controller 54 of the magazine type winding unit 4 increases the number M of trays 7 stored in the RAM or the like by one. Then (S203), the process proceeds to S204. On the other hand, if the tray 7 is not detected by the upstream sensor 211a (S202: YES), the process proceeds to S204 as it is.

  Next, when the tray 7 is detected by the downstream sensor 211b (S204: YES), the unit controller 54 of the magazine type winding unit 4 decreases the number M of trays 7 stored in the RAM or the like by one. After that (S205), the process returns to S202. On the other hand, if the tray 7 is not detected by the downstream sensor 211b (S204: NO), the process directly returns to S202. Then, while the automatic winder 1 is powered on, the unit controller 54 of the magazine type winding unit 4 repeats the processes of S202 to S205.

  Here, the tray 7 exists in a range in which the two magazine type winding units 4 in the return path 21b are arranged from the time when the tray 7 is detected by the upstream sensor 211a until the time when the tray 7 is detected by the downstream sensor 211b. Yes. Therefore, as described above, the number M of trays 7 is increased by 1 when the tray 7 is detected by the upstream sensor 211a, and the number of trays 7 is decreased by 1 when the tray 7 is detected by the downstream sensor 211b. Then, when the tray 7 does not exist within the range where the two magazine type winding units 4 are arranged on the return path 21b, the value of M becomes 0, and the tray 7 exists within this range. The value of M is the number of trays 7 existing in this range.

  And in the modification 2, when it is going to discharge the yarn feeding bobbin 8 in the magazine type winding unit 4, as shown in FIG. 12B, the number M of trays 7 stored in the RAM or the like is When the number is 1 or more (S301: NO), the process waits as it is. When the number of trays 7 stored in the RAM or the like becomes 0 (S301: YES), the yarn feeding bobbin 8 is discharged (S302).

  In the case of the modified example 2, both the two magazine type winding units 4 and the bobbin preparation device 9 are arranged on the right side of the plurality of tray type winding units 3 in the left-right direction. Compared to the form, the distance between the two magazine type winding units 4 and the bobbin preparation device 9 is short. Thereby, the operation | work which sets the yarn supply bobbin 8 stored in the branch collection | recovery path 23 to the bobbin accommodation hole 101a of the magazine apparatus 101 of the magazine type winding unit 4 can be performed easily.

  However, in the modified example 2, since the return path 21b exists between the magazine type winding unit 4 and the bobbin recovery box 110, the yarn feeding bobbin 8 is transferred from the magazine type winding unit 4 to the bobbin recovery box 110. When discharged, the yarn supply bobbin 8 discharged from the magazine type winding unit 4 may interfere with the yarn supply bobbin 8 placed on the tray 7 conveyed through the return path 21b.

  Therefore, in the second modification, as described above, the number of trays 7 existing in the range in which the two magazine type winding units 4 in the return path 21b are arranged is counted, and the tray 7 exists in this range. The yarn feeding bobbin 8 is discharged from the magazine type winding unit 4 at a timing (M = 0). Thereby, interference with the yarn feeding bobbin 8 as described above can be prevented.

  In the second modification, the yarn is fed from the magazine take-up unit 4 at a timing when the tray 7 does not exist (M = 0) in the range where the two magazine take-up units 4 are arranged on the return path 21b. Although bobbin 8 was discharged, it is not restricted to this. For example, in the third modification, as shown in FIG. 13, in the magazine type winding unit 4, the yarn feeding bobbin 8 bounced off by the jumping plate 109 is fed on the tray 7 conveyed on the return path 21b. The yarn bobbin 8 jumps over the area through which the yarn bobbin 8 passes and falls into the bobbin collection box 110. In FIG. 13, the trajectory of the yarn feeding bobbin 8 that has been bounced off is indicated by an arrow C, and a part of the halfway state of the yarn feeding bobbin 8 that has been bounced off before dropping to the bobbin collection box 110 is indicated by a dashed line. Is shown. Here, in the third modification, the yarn feeding bobbin 8 bounced off by the jumping plate 109 jumps over the region through which the yarn feeding bobbin 8 placed on the tray 7 conveyed on the return path 21b passes as described above. The size of the jump plate 109 is determined.

  In this case, the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 does not interfere with the yarn feeding bobbin 8 placed on the tray 7 conveyed through the return path 21b. The yarn feeding bobbin 8 can be discharged from the magazine type winding unit 4. In the third modification, the jump plate 109 for discharging the yarn feeding bobbin 8 corresponds to the interference avoiding means according to the present invention.

  In the third modification, the yarn feeding bobbin 8 is jumped off by the jumping plate 109 so as to jump over the region through which the yarn feeding bobbin 8 placed on the tray 7 conveyed on the return path 21b passes. Not limited. For example, a path for guiding the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 to the bobbin recovery box 110 is provided above the return path 21b, and the yarn feeding bobbin 8 is moved from the magazine type winding unit 4 to this path. The yarn feeding bobbin 8 discharged from the magazine type winding unit 4 by another method such as discharging may not pass through the region through which the yarn feeding bobbin 8 placed on the tray 7 conveyed through the return path 21b passes. May be.

  In the second and third modifications, the yarn feeding bobbin 8 discharged from the magazine type winding unit 4 is discharged to the bobbin collection box 110 disposed on the opposite side across the return path 21b. Absent. In Modification 4, as shown in FIGS. 14A and 14B, a machine base 231 is provided at the lower end of the magazine type winding unit 4, and a rotary shaft 232 a extending in the vertical direction is provided on the machine base 231. A circular turntable 232 that is rotatable at the center is provided. Then, the pegs 108 similar to those of the above-described embodiment are provided at three portions on the upper surface of the turntable 232, each having a central angle of about 120 °. In the fourth modification, the yarn feeding bobbin 8 can be attached to each of these three pegs 108.

  Further, in the fourth modification, when the turntable 232 rotates, any one of the three pegs 108 is selectively selected so that the yarn Y is fed from the yarn feeding bobbin 8 as in the above-described embodiment. It is positioned at the position where it is unwound (the “unwinding position” of the present invention), and the remaining two pegs 108 can be positioned at a position away from the unwinding position (the “discharge position” of the present invention). It has become. In the fourth modification, when the yarn Y of the yarn feeding bobbin 8 supported by the peg 108 positioned at the unwinding position is exhausted, the turntable 232 is rotated about 120 ° to thereby remove the peg 108. Is moved to the discharging position and another peg 108 is moved to the unwinding position. And the formation of the package P is continued by supplying the yarn feeding bobbin 8 from the magazine device 101 to the peg 108 which has newly moved to the unwinding position. On the other hand, the empty yarn feeding bobbin 8 supported by the peg 108 moved from the unwinding position to the discharging position is collected by, for example, an operator.

  In the case of the modified example 4, since the yarn feeding bobbin 8 of the magazine type winding unit 4 is not discharged toward the opposite side across the return path 21b, it is discharged from the magazine type winding unit 4. The yarn feeding bobbin 8 thus made does not interfere with the yarn feeding bobbin 8 placed on the tray 7 conveyed along the return path 21b. In the fourth modification, the turntable 232 that moves the peg 108 from the unwinding position to the discharging position corresponds to the bobbin discharging means according to the present invention. Moreover, in the modification 4, the turntable 232 is also an interference avoidance means according to the present invention.

  Moreover, in the modification 4, since the three pegs 108 are provided in the turntable 232, for example, the yarn Y of the yarn feeding bobbin 8 supported by one of the three pegs 108 is unwound. While winding, the empty yarn feeding bobbin 8 supported by one of the remaining two pegs 108 is collected, and the yarn feeding bobbin 8 from the magazine device 101 is loaded on the other peg 108. You may make it supply. In this case, after the yarn Y of the yarn feeding bobbin 8 supported by the one peg 108 is gone, if the turntable 232 is rotated about 120 °, the peg already holding the new yarn feeding bobbin 8 is retained. Since 108 reaches the unwinding position, the formation of the package P in the magazine type winding unit 4 can be resumed immediately.

  Further, in the fourth modification, the three pegs 108 are provided on the turntable 232, but two or four or more pegs 108 may be provided on the turntable 232. Further, the provision of the peg 108 is not limited to the rotating turntable 232. For example, a plurality of pegs 108 arranged in the left-right direction are provided on the upper surface of the slide member that slides in the left-right direction, and one of the plurality of pegs 108 is located at the unwinding position by moving the slide member in the left-right direction. The other pegs 108 may be located at the discharge position away from the unwinding position.

  In the above-described embodiment, the IC tag 45 is provided on the tray 7 and the determinations in S102 to S104 are performed based on the information stored in the IC tag 45. However, the present invention is not limited to this. In the modified example 5, the IC tag 45 is not provided on the tray 7. Correspondingly, as shown in FIG. 15, the reading device 14 (see FIG. 1) is not provided in the feedback path 21b. As shown in FIG. 15, the tray transport path 11 does not have the branch collection path 23 (see FIG. 1).

  In the modified example 5, when the tray 7 passes through the portion of the return path 21b where the remaining yarn sensor 15 is provided, the yarn is fed to the yarn feeding bobbin 8 from the detection result of the remaining yarn sensor 15, as shown in FIG. It is determined whether or not Y remains (S401). When the yarn Y does not remain on the yarn feeding bobbin 8 (S401: NO), the tray 7 is conveyed toward the ring spinning machine 2 (S402). When the yarn Y remains on the yarn feeding bobbin 8 (S401: YES), the tray 7 is conveyed toward the first bypass path 22a (S403).

  Based on the detection result of the remaining yarn sensor 16, the tray 7 conveyed to the first bypass path 22a determines whether or not the remaining amount of the yarn Y in the yarn supplying bobbin 8 is equal to or greater than a predetermined amount (S404). . If the remaining amount of the yarn Y in the yarn supplying bobbin 8 is equal to or larger than the predetermined amount (S404: YES), the outlet device 12 performs the outlet processing without removing the residual yarn by the bobbin stripper 13 (S405). . Then, when the extraction process is successful (S406: YES), the tray 7 is supplied to the tray type winding unit 3 (S407). If the dispensing process has failed (S406: NO), the tray 7 is transported toward the second bypass path 22b (S408).

  The tray 7 conveyed to the second bypass path 22b in S408 is stored in the second bypass path 22b. The yarn feeding bobbin 8 placed on the tray 7 stored in the second bypass path 22b is collected by the operator. The collected yarn supplying bobbin 8 is set in the bobbin accommodating hole 101a of the magazine device 101 of the magazine type winding unit 4. An empty yarn supply bobbin 8 is placed on the tray 7 from which the yarn supply bobbin 8 has been collected. That is, in the modified example 5, the tray 7 conveyed to the second bypass path 22b in S408 waits on the second bypass path 22b until the collection of the yarn feeding bobbin 8 is completed (S409: NO). And when collection | recovery of the yarn feeding bobbin 8 is completed (S409: YES), it returns to the return path | route 21b from the 2nd bypass path | route 22b (returns to S401). The tray 7 returned to the return path 21b is confirmed to have no yarn Y remaining on the yarn feeding bobbin 8 (S401: YES), and is conveyed toward the ring spinning machine 2 (S402).

  On the other hand, when the remaining amount of yarn in the yarn supplying bobbin 8 is less than the predetermined amount (S404: NO), the remaining yarn on the yarn supplying bobbin 8 is removed in the bobbin stripper 13 (S410). Thereafter, the tray 7 is conveyed to the second bypass path 22b through the supply path 21a (S411). At this time, the tray 7 passes through the spouting device 12, but since the yarn Y does not remain in the yarn feeding bobbin 8, the spouting processing by the spouting device 12 is not performed. The tray 7 conveyed to the second bypass path 22b in S411 is returned to the return path 21b (returns to S401). The tray 7 returned to the return path 21b is determined that the yarn Y does not remain in the yarn supplying bobbin 8 (S401: YES), and is conveyed toward the ring spinning machine 2 (S402). Here, when the yarn supplying bobbin 8 in which the spout processing has failed is stored in the second bypass path 22b, an empty yarn supplying bobbin 8 from which the remaining yarn of the yarn supplying bobbin 8 has been removed by the bobbin stripper 13 is placed. This hinders the return of the tray 7 to the return path 21b. For this reason, when the yarn feeding bobbin 8 for which the spouting process has failed in S405 is conveyed to the second bypass path 22b, it is preferable to notify the operator to encourage the collection of the yarn feeding bobbin 8 for which the spouting process has failed.
