The bobbin separating section 24 supplies the bobbins 9 individually. The bunch removing section 72 removes bunched thread on the bobbins 9 supplied from the bobbin separating section 24. The tray placing section 73 places the bobbins, from which the bunched thread has been removed by the bunch removing section 72, on the conveyance trays 21.

Description

  The present invention mainly relates to a bobbin supplying device that supplies a yarn supplying bobbin formed by winding a yarn around a bobbin tube to a winding device.

  As a device for supplying spun yarn that has been spun by a spinning machine and wound on a yarn feeding bobbin (hereinafter sometimes simply referred to as “bobbin”) to a winding device such as an automatic winder, a parts feeder type feeding device is available. It is known (see, for example, Patent Document 1).

  The bobbin separated and supplied by the supply device of Patent Document 1 is then used in the bobbin preparation device so that the automatic winder winding unit can automatically perform the bobbin winding operation in the bobbin preparation section. Supplied. This bobbin preparation device performs preprocessing of the bobbin. Specifically, the bottom bunch that is the end of winding when the bobbin is formed by the spinning machine is removed, and the yarn end of the end of winding that is freed by removing the bottom bunch is captured, and the bobbin tube of the bobbin is Inserted inside. By inserting the yarn end into the bobbin tube of the bobbin in this way, the automatic winder can apply compressed air to the bobbin tube of the bobbin to blow up the yarn end.

  The blown-up yarn end is caught by a lower yarn catching device that catches the bobbin side yarn provided in the winder unit of the automatic winder, and guided to the yarn joining device. Thereafter, the bobbin-side yarn end (lower yarn) guided to the yarn joining device is coupled to the package-side yarn end (upper yarn) and then wound on the package.

  Further, in the bobbin preparation device, the bottom bunch is removed as described above, and at the same time, the yarn end of the yarn feeding bobbin wound around the bobbin tube of the yarn feeding bobbin (the winding start when the yarn feeding bobbin is formed by the spinning machine). (Hereinafter also referred to as “seed yarn”) is also removed. Thus, in the automatic winder, the yarn is prevented from being entangled when all the yarn is wound up from the yarn supplying bobbin, so that all of the yarn wound around the yarn supplying bobbin can be smoothly unwound.

  If the bobbin preparation device cannot perform pre-processing well and the seed yarn or bunch winding part remains on the yarn feeding bobbin, the seed yarn or bunch winding is applied to the yarn to be unwound from the yarn feeding bobbin. Will get tangled. The entangled yarn cannot be unwound and causes a tension breakage, which causes a reduction in operating efficiency of the winding device.

  Patent Document 2 discloses a bunch winding and unwinding device that removes bunch winding formed on a bobbin by unwinding. The bunch unwinding device includes a suction case, an air duct, a rotary cutter, and a tray rotating roller.

  With this configuration, the bobbin rotates in conjunction with the tray rotating roller brought into contact with the tray that supports the bobbin and rotated. Then, a bottom bunch (bunch winding) formed on the bobbin is sucked into the suction case that is set to a negative pressure. The sucked bottom bunch is cut by a rotary cutter arranged inside the suction case. As described above, the bunch wound yarn of the bottom bunch wound around the bobbin is unwound.

JP-A-6-16226 JP 2008-247517 A

  However, in order to provide a dedicated bunch unwinding device as in Patent Document 2, a preparation section for pre-processing is increased in the conveyance path for conveying the bobbin supplied to the conveyance tray to the automatic winder. It is necessary to take. Since this leads to an increase in the installation area of the apparatus, there remains room for improvement from the viewpoint of miniaturization.

  In addition, the configuration of the bunch winding and unwinding device shown in Patent Document 2 requires various configurations including a mechanism for rotating the bobbin, resulting in a complicated device. Also, depending on how the yarn is wound around the bobbin, the yarn may be wound many times to form the bottom bunch, and in this case, it is necessary to rotate the bobbin by the number of rounds of the bottom bunch yarn in the bunch winding and unwinding device. As a result, work efficiency was reduced.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a configuration that can be supplied to a transport tray in a state where a bunch winding of a bobbin is removed while realizing a small installation area.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the 1st viewpoint of this invention, the bobbin supply apparatus of the following structures is provided. That is, the bobbin supply device includes a supply unit, a bunch removal unit, and a placement unit. The supply unit supplies bobbins individually. The bunch removing unit removes the bunch winding of the bobbin supplied from the supply unit. The placement unit places the bobbin from which the bunch winding has been removed by the bunch removal unit on the transport tray.

  Thereby, since the bobbin supply device includes the bunch removing unit, it is not necessary to provide a bunch removing mechanism in a later process. Further, it is possible to avoid a yarn pulling state in which the bunch winding or the seed yarn is removed and conveyed by the conveyance tray.

  In the bobbin supply device, it is preferable that the bunch removing unit removes the bottom bunch.

  Thereby, the bottom bunch in which the yarn end is wound around the bobbin tube is removed, so that a yarn drawing state that is generated when the bottom bunch is unwound can be prevented.

  The bobbin supply device preferably has the following configuration. That is, the bunch removing unit includes a bobbin path, a suction port member, an opening / closing mechanism, and a cutting mechanism. The bobbin path is formed to pass through a work position for removing the bottom bunch. The suction port member is formed with a suction port that is connected to a negative pressure source and generates a suction flow. The opening / closing mechanism is disposed in the suction port member and opens / closes the suction port. The cutting mechanism cuts the yarn forming the bottom bunch sucked from the bobbin.

  Accordingly, the bottom bunch of the bobbin can be sucked from the suction port, and the yarn forming the bottom bunch can be cut and removed by the cutting mechanism. In particular, since the bottom bunch is removed and removed from the bobbin by suction when the bobbin is not attached to the transport tray, the configuration is significantly larger than the conventional configuration where the bottom bunch is removed while rotating the bobbin. Can be simplified.

  The bobbin supply device preferably has the following configuration. That is, the opening / closing mechanism is a shutter portion made of a plate member. The cutting mechanism is disposed at the periphery of the plate member and cuts the yarn.

  Thereby, opening and closing of the suction port can be performed with a simple configuration. In addition, the opening and closing of the suction port and the cutting of the yarn can be easily linked.

  In the bobbin supply device, it is preferable that the bunch removing unit includes a drive unit that drives the suction port member to be movable back and forth with respect to the bobbin at the working position.

  Thereby, since the suction port can be moved, the bottom bunch can be sucked and removed by strongly applying the suction flow to the bottom bunch while the suction port is covered on the support side end of the bobbin. Therefore, reliable removal of the bottom bunch is realized.

  The bobbin supply device preferably has the following configuration. That is, the bobbin supply device includes a holding mechanism and an air nozzle. The holding mechanism holds the unwinding side end of the bobbin in the working position. The air nozzle is disposed in the vicinity of the suction port inside the suction port member, and injects air toward the downstream side of the suction flow.

  As a result, the bottom bunch can be reliably unwound by blowing air from the air nozzle. Further, since the holding mechanism holds the bobbin during the bottom bunch removal operation, the bottom bunch removal operation can be performed smoothly with the bobbin stabilized (the bobbin itself is not sucked and clogged in the suction port).

  In the bobbin supply device, it is preferable that the supply unit is a bobbin separation device that separates a plurality of loaded bobbins individually.

  As a result, a plurality of loaded bobbins can be separated and placed on the transport tray while removing the bottom bunch. As a result, the work in the post process can be simplified. Further, since there is no thread drawing, the yarn is not entangled with the transport tray.

  The bobbin supply device preferably has the following configuration. That is, the bobbin separation device includes a bobbin input unit and a bobbin extraction unit. A plurality of bobbins are input to the bobbin input portion. The bobbin take-out unit takes out the bobbin from the bobbin group thrown into the bobbin throw-in unit. The bobbin take-out unit separates the bobbin while conveying the bobbin substantially vertically upward with respect to the installation surface of the bobbin input unit.

  As a result, the bobbin is separated while being conveyed substantially vertically upward at the bobbin take-out portion. Therefore, the installation area necessary for separating the bobbin can be reduced.

  The bobbin supply device preferably has the following configuration. That is, this bobbin supply device includes an ascending path and a descending path. The rising path conveys the bobbin upward. The descending path conveys the bobbin downward. The bobbin take-out portion is disposed in the ascent path. In the descending path, the bunch removing unit and the mounting unit are arranged.

  Thereby, a rational layout is realized in which the bobbin is separated while being conveyed upward, and the bunch is removed and placed on the conveyance tray while being conveyed downward. Moreover, since the bunch removing unit and the tray mounting unit are arranged in the vertical direction in the descending path, the entire installation area can be greatly reduced.

  In the bobbin supplying device, in the descending path, on the upstream side of the bunch removing unit, a direction aligning supplying unit that detects the direction of the bobbin and aligns the bobbin in a certain direction and then sends the bobbin to the bunch removing unit. Is preferably provided.

  Thereby, the direction of the bobbin is detected in the direction aligning supply unit, and the bobbin always directed in a certain direction is supplied to the bunch removing unit. Therefore, the removal process in the bunch removal unit can be simplified. Specifically, since the bottom bunch is always supplied to the side where the mechanism capable of removing the bottom bunch is arranged, it is not necessary to adjust the direction of the bobbin at the bunch removing unit.

  According to the 2nd viewpoint of this invention, the winding system of the following structures is provided. That is, the winding system includes the bobbin supply device, the winding device, and the bobbin preparation device. The winding device winds a yarn from the bobbin to form a package. The bobbin preparation device prepares the take-up device to be in a state where it can process the bobbin while carrying the carrying tray supplied with the bobbin by the supply unit to the take-up device. The bobbin preparation device is provided with a bobbin supply path for transporting a transport tray supplied with bobbins from the bobbin supply device to the winding device. The bobbin supply path is provided with a spout device for processing the yarn end on the end side when the yarn feeding bobbin is wound up.

  Thereby, since the bunch removal part is provided in the bobbin supply apparatus side, it is not necessary to provide a bottom bunch removal part in the bobbin preparation apparatus. Accordingly, it is possible to reduce the size of the apparatus.

  In the winding system, the bobbin preparation device may be provided with a second bunch removing unit that removes the bottom bunch.

  In this case, the bottom bunch of the bobbin can be surely removed by the two bunch removal processes including the process by the bunch removing unit in the bobbin supply device and the process by the second bunch removing device.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front sectional view showing an overall configuration of a bobbin separation and supply device 12 according to an embodiment of the present invention. FIG. 2 is a perspective view of the bobbin separation and supply device 12. FIG. 3 is a perspective view of the bobbin extraction portion 23. FIG. 4 is an enlarged side cross-sectional view of the bobbin extraction part 23.

  An automatic winder system (winding system) 10 according to an embodiment of the present invention includes an automatic winder (winding device) including a plurality of winder units (not shown), a bobbin transport device 11, and a bobbin separation and supply device 12. It is equipped with.

  The winder unit is configured to form a package by unwinding the spun yarn wound around the bobbin 9 and winding it back onto the take-up bobbin.

  The bobbin transport device 11 includes a bobbin transport path 20 configured by a conveyor and the like, and a large number of transport trays 21 transported on the bobbin transport path 20. As shown in FIG. 1, the transport tray 21 is configured so that the bobbin 9 can be placed in a substantially upright state. The bobbin transport path 20 is configured so that the transport tray 21 on which the bobbin 9 is placed can be transported to each winder unit (not shown). Thereby, the bobbin 9 can be automatically supplied to each winder unit.

  By the way, the bobbin 9 is wound with spun yarn spun by a spinning machine or the like. The bobbin 9 manufactured by the spinning machine is put in a container 8 or the like and is carried to an automatic winder. If the operator places the bobbins 9 in the container 8 on the transport tray 21 one by one manually, the burden on the operator increases. Therefore, the bobbin separation and supply device 12 of the present embodiment is configured to automatically separate the bobbins 9 one by one (individualized) and place them on the transport tray 21.

  As shown in FIGS. 1 and 2, the bobbin separation and supply device 12 of the present embodiment includes a bobbin insertion unit 22, a bobbin extraction unit 23, a bobbin direction alignment unit (direction alignment supply unit) 71, and a bunch removal unit 72. And a tray mounting portion (mounting portion) 73.

  The bobbin 9 that has been carried in the container 8 is loaded into the bobbin loading unit 22. The bobbin group thrown into the bobbin throwing-in part 22 is picked up one by one by the bobbin taking-out part 23 and individualized. In other words, the bobbin input unit 22 and the bobbin take-out unit 23 constitute a bobbin separation unit (supply unit) 24 that individually separates a plurality of loaded bobbins 9.

  The bobbin inserting portion 22 includes a swing member 31 configured to be swingable. The swing member 31 swings at a predetermined angular stroke to supply the bobbin 9 to the bobbin take-out portion 23 while keeping the bobbin group input to the bobbin input portion 22 and crushing it. be able to. Thereby, since it is possible to prevent a large amount of bobbins 9 from being supplied to the bobbin take-out portion 23 at a time, the bobbin take-out portion 23 can reliably take up the bobbins 9 one by one.

  In addition, the bobbin loading unit 22 includes a cutter 43. The cutter 43 is configured in a scissors shape, and is configured to be able to cut the yarn that has come out of the bobbin 9 by being driven by a drive source (not shown). When the bobbin 9 is transported from the bobbin loading part 22 to the bobbin take-out part 23, the cutter 43 cuts the thread even when the thread has come out from the bobbin 9 (when there is a thread drawing). I can leave. As a result, even when the bobbin 9 is picked up by the bobbin take-out portion 23 and stirred by the bobbin tray 26, occurrence of yarn entanglement and the like can be prevented and individualization can be performed appropriately.

  The bobbin take-out part 23 is configured as a conveyor arranged in the vertical direction. Specifically, as shown in FIG. 3 and FIG. 4, the bobbin take-out portion 23 is arranged at equal intervals in the longitudinal direction of the endless annular strip 25 on the endless annular strip 25 and the outer surface of the endless annular strip 25. And a plurality of bobbin dishes 26 attached to the.

  As shown in FIG. 3, the endless annular band 25 is a band-shaped (sheet-shaped) looped between two upper and lower rotating rollers 37, 37 arranged so that the rotation axes are parallel to each other. It is configured as a member. The upper rotary roller 37 is connected to an output shaft of a stepping motor 38 as a drive source via a drive transmission belt or the like. In this configuration, when the stepping motor 38 is operated, the endless annular band 25 is circulated and the bobbin tray 26 attached to the endless annular band 25 is driven in the vertical direction.

  Moreover, by setting it as the structure which attaches the bobbin dish 26 to the endless annular strip 25, the bobbin dish 26 can be supported stably compared with the structure which attaches a bobbin dish to an endless chain, for example. Further, since the back side of the bobbin tray 26 is closed by the sheet-like endless annular band 25, the bobbin on the bobbin tray 26 does not fall to the back side of the apparatus. .

  The bobbin tray 26 has a rectangular surface as a whole so that the bobbin 9 can be placed thereon. The rectangular bobbin tray 26 is attached to the endless annular band 25 so that the longitudinal direction thereof is parallel to the rotational axis direction of the rotating roller 37. As a result, the bobbin tray 26 can place the bobbin 9 parallel to the rotation axis of the rotating roller 37. The depth of the bobbin dish 26 (the length of the rectangular surface in the direction orthogonal to the longitudinal direction) is such that two bobbins 9 cannot be laid side by side. With this configuration, the endless annular band 25 is circulated and driven, so that the bobbins 9 in the bobbin loading portion 22 are placed one by one on the bobbin tray 26 and conveyed vertically upward with respect to the apparatus installation surface. It has become. In this way, the bobbin groups in the bobbin inserting section 22 can be taken up (individualized) one by one.

  Here, as a device for individualizing the bobbin, for example, a configuration as disclosed in JP-A-8-337317 is also known. In the pipe yarn supply device described in Japanese Patent Laid-Open No. 8-337317, bobbins are individualized by feeder balls. This feeder ball requires a large space in the horizontal direction due to its configuration. In this regard, the bobbin take-out unit 23 provided in the bobbin separation and supply device 12 of the present embodiment is individualized by transporting the bobbin 9 in the vertical direction, and therefore does not require much space in the horizontal direction. Therefore, the bobbin separation and supply device 12 can be downsized as compared with the conventional configuration.

  Moreover, since the pipe thread supply device described in Japanese Patent Application Laid-Open No. 8-337317 was configured to perform individualization while dropping the bobbin, the position where the bobbin is unloaded by the unloading device is a high position. I had to. Since the bobbin loading position is thus high, the pipe thread supply device disclosed in JP-A-8-337317 has poor visibility and workability. In this regard, the bobbin separation and supply device 12 of the present embodiment is configured to be individualized by transporting the bobbin 9 upward, so that the loading position of the bobbin 9 can be set to a low position. Thereby, visibility and workability are greatly improved.

  The bobbin separation and supply device 12 includes a bobbin separation member 41 that can contact the bobbin 9 conveyed by the bobbin tray 26. The bobbin separating member 41 is configured as a metal wire (linear member) arranged along the region where the bobbin 9 is conveyed by the bobbin tray 26. The bobbin tray 26 is formed with a slit for allowing the bobbin separating member 41 to pass therethrough. Further, the bobbin separating member 41 is appropriately bent, and an extruding portion 42 is formed for slightly pushing and shaking the bobbin 9 on the bobbin tray 26.

  Here, as described above, the size of the bobbin tray 26 is set such that two bobbins 9 cannot be mounted side by side. However, it is also conceivable that a plurality of bobbins are placed on the bobbin tray 26 such that the bobbin 9 is placed on the bobbin 9. In this respect, since the bobbin separating member 41 is provided in the bobbin take-out portion 23 of the present embodiment, even when the bobbin 9 is superposed vertically and placed on the bobbin tray 26, the pushing portion 42 of the bobbin separating member 41 is moved to the bobbin 9. By pushing and shaking, the extra bobbins 9 can be dropped and can be individually separated one by one.

  For example, as shown in FIG. 4, when two bobbins 9 are placed on one bobbin tray 26, when the bobbin tray 26 reaches the position of the pushing portion 42, the two bobbins 9 are separated from each other. By being pushed by the member 41, a shaking action is given, and the bobbin 9 that is overlaid is dropped downward from the take-up side end of the bobbin dish 26. As described above, the bobbin separating member 41 having the push-out portion 42 is arranged along the conveying direction of the bobbin 9, and the extra bobbin 9 riding on the bobbin dish 26 can be dropped from the bobbin dish 26. it can.

  The bobbin 9 transported upward by the bobbin take-out unit 23 is supplied to the bobbin direction aligning unit 71 via a bobbin buffer unit (holding unit) 44 in which the bobbin 9 can be temporarily stored.

  The bobbin direction aligning portion 71 discriminates the unwinding side end portion and the support side end portion of the bobbin 9 received from the bobbin takeout portion 23 and rotates the unwinding side end portion downward, It is dropped on the lower bunch removing unit 72.

  Hereinafter, the unwinding side and the supporting side of the bobbin 9 will be described in detail with reference to FIG. FIG. 5 is a diagram for explaining the support side, the unwinding side, and the bunch winding of the bobbin 9.

  The bobbin 9 is obtained by winding the spun yarn generated by the spinning machine in the previous process around the bobbin tube 9t. In FIG. 1 and the like, the bobbin tube of the bobbin 9 is drawn so as not to be tapered for convenience of drawing, but actually, as shown in FIG. 5, the bobbin tube 9t has a slight taper. Is formed. In the spinning machine, the spun yarn is wound up from the large-diameter side end of the bobbin tube 9t toward the small-diameter side end.

  In FIG. 5, the unwinding side end of the bobbin 9 is denoted by reference numeral 9 p, and the support side end is denoted by reference numeral 9 q. Since the bobbin tube 9t is tapered, the unwinding side end 9p is slightly thinner than the support side end 9q. The unwinding side of the bobbin 9 is the side on which the diameter of the bobbin tube 9t is reduced, and means the direction in which the yarn wound around the bobbin 9 is unwound by the winder unit. The support side of the bobbin 9 is the side on which the diameter of the bobbin tube 9t is enlarged, and is supported by the transport tray 21 in a state where the bobbin 9 is placed on the transport tray 21 by a tray placement unit 73 described later. Means the other side.

  In addition, since the structure which discriminate | determines the unwinding side edge part and support side edge part of the bobbin 9 is well-known, for example, it is disclosed by Unexamined-Japanese-Patent No. 8-169525, detailed description is abbreviate | omitted.

  The bobbin buffer unit 44 is configured so that, for example, several bobbins 9 are stocked between the bobbin take-out unit 23 and the bobbin direction aligning unit 71 and can be supplied downstream in response to a command. As a result, even if the bobbin 9 cannot be continuously picked up by the bobbin take-out part 23 due to the bobbin 9 falling from the bobbin tray 26, the bobbin direction aligning part 71, which is the downstream apparatus, The bobbin 9 can be supplied from the bobbin buffer unit 44 to the bunch removing unit 72 and the tray mounting unit 73 without interruption, so that the efficiency of the apparatus is not lowered.

  The bunch removing unit 72 is for removing the bunch winding and seed yarn formed on the bobbin 9. Hereinafter, the configuration of the bunch removing unit 72 will be described in detail with reference mainly to FIGS. FIG. 6 is a front view of the bunch removing unit 72 included in the bobbin separation and supply device 12. 7 is a cross-sectional view taken along the line AA in FIG. 8 is a cross-sectional view taken along the line BB in FIG. FIG. 9 is a front sectional view showing a state in which the cylindrical body 52 is placed on the support side end portion 9q of the bobbin 9 from the state of FIG. 8 and the bottom bunch 9a is sucked.

  The bunch removing unit 72 includes a housing 81, a rotary feeder 82, a suction mechanism 51, and a clamp mechanism (holding mechanism) 93 as main components.

  Here, bunch winding and seed yarn will be briefly described with reference to FIG. That is, in the bobbin 9 in which the yarn is just wound up from the large diameter side to the small diameter side of the bobbin tube 9t, the yarn end is free. Therefore, in the bobbin 9 in this state, a yarn may come out when the bobbin 9 is transported from the spinning machine to the bobbin separation and supply device 12 and the bobbin 9 may be entangled with each other.

  Therefore, as shown in FIG. 5, the yarn is spirally wound around the surface of the bobbin 9 from the small diameter side to the large diameter side, and the yarn is wound around the support side end 9q of the bobbin tube 9t. Forming a winding is performed. As a result, the yarn end is not free, so that the yarn can be prevented from coming out of the bobbin 9 being conveyed. The portion of the thread that is spirally wound from the small diameter side to the large diameter side on the surface of the thread layer of the bobbin 9 is referred to as a backwind thread 9d, and is wound around the support side end 9q of the bobbin tube 9t. This portion is called a bottom bunch 9a.

  The bottom bunch 9a is formed at the end of the yarn winding by the spinning machine, and the yarn winding start portion with respect to the bobbin tube 9t may be referred to as a seed yarn 9c. This seed yarn 9c may be considerably long depending on how the yarn is wound around the bobbin 9. In particular, the seed yarn 9c is not an automatic doffing device, but a bobbin is manually doffed by an operator. This tendency is often seen in spinning machines. Further, in the hand-drawn spinning machine described above, the number of times of yarn winding when forming the rod winding in the bottom bunch 9a may increase. In these cases, the removal of the seed yarn 9c and the bottom bunch 9a takes a lot of time and reduces the production efficiency. Therefore, the bobbin separation and supply device 12 of the present embodiment includes a bunch removing unit 72 that can reliably and quickly remove the bottom bunch 9a and the seed yarn 9c.

  The housing 81 rotatably supports the rotary feeder 82 and includes a direction changing plate 91. The direction change plate 91 is configured as a flat plate-like member directed obliquely. This direction changing plate 91 changes the direction of the bobbin 9 falling from the bobbin direction aligning portion 71 with the unwinding side facing down, by approximately 90 °, so that the unwinding side faces the far side from the direction changing plate 91. Guide 9 directions.

  The rotary feed body 82 is configured by combining plate-like partitions, and the interior of the rotary feed body 82 is partitioned into six spaces by the partitions as shown in FIG. Each space (hereinafter sometimes referred to as a bobbin accommodating space 94) is formed in an elongated shape, and is arranged so that its longitudinal direction is parallel to the axis of the rotary feed body 82. The six bobbin housing spaces 94 are arranged at equal intervals of 60 ° in the circumferential direction, and are configured to open the radially outer side. Accordingly, one bobbin 9 can be accommodated in each of the bobbin accommodating spaces 94 from the outside in the radial direction of the rotary feed body 82.

  The rotary feed body 82 is supported by the housing 81 so that its central axis is slightly inclined from the horizontal. Specifically, the central axis of the rotary feeder 82 is inclined so that the end portion on the side farther from the direction changing plate 91 (the left end portion in FIG. 1) is slightly lower. Accordingly, the bobbin housing space 94 is also arranged to be slightly inclined in the same direction.

  The housing 81 is formed with a bobbin path 95 including a substantially arc-shaped portion disposed around the central axis of the rotary feeder 82. Further, a substantially L-shaped regulating member 85 arranged along the bobbin path is fixed to the housing 81. The restricting member 85 can restrict the bobbin 9 from coming out of the bobbin accommodating space 94 by coming into contact with the end of the bobbin 9 about to exit from the bobbin accommodating space 94 with its own weight.

  The bobbin path 95 includes, in order from the upstream to the downstream of the bobbin path 95, a receiving position P1 for receiving the bobbin 9 from the bobbin direction aligning unit 71, a work position P2 for performing the bunch removal work on the bobbin 9, A discharge position P3 for sending the bobbin 9 from which the bunch has been removed to the tray mounting portion 73 is set.

  The receiving position P1 is located above the housing 81 and above the central axis of the rotary feeder 82. At the receiving position P1, the upper portion of the housing 81 is opened. Accordingly, the bobbin 9 supplied from the bobbin direction aligning portion 71 is put into the bobbin accommodating space 94 of the rotary feeder 82 at the receiving position P1. In addition, due to the action of the bobbin direction aligning portion 71 and the direction changing plate 91, the bobbin 9 enters the bobbin accommodating space 94 such that the unwinding side faces the side far from the direction changing plate 91.

  The work position P <b> 2 is disposed at the lower part of the housing 81 and below the central axis of the rotary feeder 82. In this working position, the bobbin 9 is held so that its position does not move by clamping the unwinding side end 9p by a clamp mechanism 93 described later. In this state, the bunch winding (bottom bunch) formed on the support side end portion 9q of the bobbin 9 and the seed yarn are removed. A detailed configuration for the bunch removing operation will be described later.

  The discharge position P3 is located below the housing 81 and next to the work position P2. Since the restricting member 85 is interrupted at the discharge position P3, the bobbin 9 that has entered the bobbin housing space 94 of the rotary feeder 82 is discharged obliquely downward by its own weight. The discharged bobbin 9 is sent to the tray mounting unit 73 via the bobbin chute 27.

  A drive motor 92 is attached to the housing 81, and the drive motor 92 can rotate the rotary feeder 82 in one direction by 60 °. Thereby, the rotary feeder 82 can sequentially feed the bobbins 9 received at the receiving position P1 one by one along the bobbin path 95 in the order of the work position P2 and the discharge position P3.

  Next, a configuration for removing the bottom bunch and the seed yarn at the work position P2 will be described in detail with reference to FIG.

  As shown in FIG. 8, a suction mechanism 51 for sucking and removing the bottom bunch of the bobbin 9 is provided on the side where the support side of the bobbin 9 is located at the work position P2. A clamp mechanism 93 for fixing the bobbin 9 is disposed on the side where the unwinding side of the bobbin 9 is located.

  The clamp mechanism 93 includes a base member 96 having a V-shaped recess, a pressing member 97 facing the base member 96, and an air cylinder 98 as an actuator that drives the pressing member 97.

  As shown in FIG. 7, the V-shaped recess formed in the base member 96 is smoothly connected to the edge of the regulating member 85. Further, as shown in FIG. 6 and the like, all of the six bobbin housing spaces 94 included in the rotary feeder 82 are inclined so that the unwinding side of the bobbin 9 is lowered. Accordingly, when the bobbin 9 is inserted into the bobbin housing space 94 at the receiving position P1, the bobbin 9 is rotated and fed even if the bobbin 9 is located near the center or near the direction changing plate 91 in the bobbin housing space 94. As it is sent by the rotation of the body 82, the bobbin 9 moves under its own weight, and is gradually brought closer to the lower side. Therefore, when the bobbin 9 is sent to the work position P2, the unwinding side end portion 9p of the bobbin 9 is inserted between the base member 96 and the pressing member 97 of the clamp mechanism 93 so that it can be clamped. Can do.

  The suction mechanism 51 includes a cylindrical body 52 that can move in a direction along the longitudinal direction of the bobbin housing space 94. When the bobbin 9 is held by the clamp mechanism 93 at the work position P <b> 2, the cylindrical body 52 has an opening arranged on an extension line of the axis of the bobbin 9. In addition, the cylindrical body 52 is connected to an appropriate negative pressure source (for example, a blower) via a flexible pipe 53. Thereby, a suction flow can be generated in the opening of the cylindrical body 52 and in the cylindrical body 52.

  Further, a shutter cutter (shutter unit, opening / closing mechanism) 84 is disposed inside the cylindrical body 52, and the shutter cutter 84 switches between a closed state and an opened state of the cylindrical body 52. Can do. The shutter cutter 84 is composed of a plate member, and is connected to an actuator (cutting mechanism) (not shown) disposed around the shutter cutter 84. The thread can be cut by driving the cutting mechanism and closing the shutter cutter 84 so as to sandwich the thread. However, for example, a member having a cutting blade may be arranged separately from the shutter cutter 84 and driven by a cutting mechanism to cut the yarn.

  The bunch removing unit 72 includes an air cylinder (actuator, driving unit) 54 for driving the cylindrical body 52 forward and backward in the axial direction. Therefore, the cylinder 52 is driven between the position (FIG. 9) that covers the support side end 9q of the bobbin 9 and the position (FIG. 8) that comes out of the support side end 9q of the bobbin 9 by driving the air cylinder 54. Thus, the bobbin 9 can be moved along the longitudinal direction.

  Further, an air blast nozzle (air nozzle) 55 is formed in the cylindrical body 52. The air blast nozzle can inject air blast toward the inside of the cylindrical body 52 (downstream side of the suction flow). The air blast nozzle 55 is arranged at six places in the circumferential direction so as to open in the inner wall of the cylindrical body 52.

  With the above configuration, in order to remove the bunch winding of the bobbin 9 at the work position, the unwinding side end of the bobbin 9 is first clamped by the clamp mechanism 93 and fixed so as not to move. Next, the closed shutter cutter 84 is opened to generate a suction flow in and near the opening of the cylindrical body 52, and the cylindrical body 52 is moved by the air cylinder 54 while an air flow is jetted from the air blast nozzle 55. The bobbin 9 is placed on the end of the support side. The length over which the cylindrical body 52 is covered can be appropriately set in consideration of the length of the bobbin tube of the bobbin 9 and the like.

  Then, the bottom bunch 9 a wound around the support side of the bobbin 9 is pulled out and sucked into the cylindrical body 52. However, it is also conceivable that the bottom bunch 9a is removed so that the bottom bunch 9a is gradually unwound from the yarn end without the bottom bunch 9a coming off at once. After a predetermined time has passed in this state, the yarn 9b forming the bottom bunch 9a sucked into the cylindrical body 52 is cut by closing the shutter cutter 84.

  Next, after returning the cylindrical body 52 to the position of FIG. 8, the above cycle is repeated an appropriate number of times. By controlling the operation cycle to be repeated a plurality of times in this manner, the bottom bunch 9a can be more reliably removed. The number of operation cycles can be set by performing an appropriate operation on the control unit that controls the bunch removing unit 72. As a specific example of operation, it is conceivable that one cycle is completed in about 1 second, for example, and the above cycle is performed twice for each bobbin 9.

  8 and 9, the bobbin seed yarn 9c at the work position P2 is short from the beginning, and is not cut by the shutter cutter 84. When a bobbin in which the seed yarn 9c protrudes to some extent is supplied, the seed yarn 9c is also cut short by the shutter cutter 84 simultaneously with the yarn 9b forming the bottom bunch 9a.

  As described above, the bottom bunch 9a and the seed yarn 9c of the bobbin 9 are removed. Thereafter, the bunch removing unit 72 releases the clamp by the clamp mechanism 93, drives the rotary feeder 82, sends the bobbin 9 to the discharge position, and drops it via the bobbin chute 27. Under the bobbin chute 27, the transport tray 21 is waiting, and the bobbin 9 from the bobbin chute 27 is placed on the transport tray 21.

  The bobbin separating and supplying apparatus 12 configured in this way is configured to remove the bobbin 9 from the group of bobbins loaded into the bobbin loading unit 22 and the pickup side end of the bobbin dish 26 (the end attached to the endless annular band 25) Is picked up by scooping at the opposite end). Then, the bobbin 9 can be individualized while being transported, and the bottom bunch 9a and the seed yarn 9c can be removed and placed on the transport tray 21.

  Next, the bobbin preparation device provided in the bobbin transport path 20 for transporting from the bobbin separation and supply device 12 to each winder unit of the automatic winder will be described. FIG. 10 is a schematic plan view of the bobbin preparation device 17.

  The bobbin preparation device 17 is disposed in a section (so-called preparation section) on the bobbin conveyance path 20 and upstream of the winder unit and downstream of the bobbin separation and supply device 12. The bobbin preparation device 17 includes a mouthing device 18 that mouths the bobbin 9 so that the yarn of the bobbin 9 can be easily captured by the winder unit.

  The structure of the mouthing device 18 is known, but will be briefly described below. The lead-out device 18 unwinds the yarn from the surface of the bobbin 9 by applying a suction flow to the bobbin 9 that has been carried on the bobbin conveyance path 20 on the conveyance tray 21. The unwound yarn end is inserted into the cylindrical bobbin 9 in advance. By this preparation operation, the yarn end of the bobbin 9 can be easily captured and the winding of the yarn can be started smoothly in the winder unit downstream of the lead-out device 18.

  As described above, the bobbin separation and supply device 12 of the present embodiment includes the bobbin separation unit 24, the bunch removal unit 72, and the tray placement unit 73. The bobbin separation unit 24 supplies the bobbins 9 individually. The bunch removing unit 72 removes the bunch winding (bottom bunch 9a) of the bobbin 9 supplied from the bobbin separating unit 24. The tray placing unit 73 places the bobbin 9 from which the bunch winding has been removed by the bunch removing unit 72 on the transport tray 21.

  Thereby, since the bobbin separation supply apparatus 12 is provided with the bunch removal part 72, it is not necessary to provide a bunch removal mechanism in a subsequent process. Further, it is possible to avoid a yarn pulling state in which the bunch winding or the seed yarn is removed and conveyed by the conveyance tray.

  Further, in the bobbin separation and supply device 12 of the present embodiment, the bunch removing unit 72 is configured to remove the bottom bunch 9a.

  As a result, the bottom bunch 9a having the yarn end wound around the bobbin tube 9t is removed, so that a yarn drawing state that is generated when the bottom bunch 9a is unwound can be prevented.

  Further, in the bobbin separating and supplying apparatus 12 of the present embodiment, the bunch removing unit 72 includes a bobbin path 95, a cylinder (suction port member) 52, a shutter cutter 84, and a cutting mechanism. The bobbin path 95 is formed so as to pass through the work position P2 for removing the bottom bunch 9a. The cylindrical body 52 is formed with a suction port that is connected to a negative pressure source and generates a suction flow. The shutter cutter 84 is disposed in the cylindrical body 52 and opens and closes the suction port. The cutting mechanism cuts the yarn 9b forming the bottom bunch 9a sucked from the bobbin 9.

  Accordingly, the bottom bunch 9a of the bobbin 9 can be sucked from the suction port, and the yarn 9b forming the bottom bunch 9a can be cut and removed by the cutting mechanism. In particular, since the bottom bunch 9a is removed from the bobbin 9 by removing the bobbin 9 in the state where the bobbin 9 is not attached to the transport tray 21, the bottom bunch is removed while rotating the bobbin. The configuration can be greatly simplified.

  Further, in the bobbin separation and supply device 12 of this embodiment, the suction port is opened and closed by the shutter cutter 84 made of a plate member. Further, the cutting mechanism is disposed in the peripheral portion of the plate member and cuts the yarn 9b.

  Thereby, opening and closing of the suction port can be performed with a simple configuration. Further, the opening / closing of the suction port and the cutting of the yarn 9b can be easily linked.

  Further, in the bobbin separation and supply device 12 of the present embodiment, the bunch removing unit 72 includes an air cylinder 54 that drives the cylindrical body 52 to be movable forward and backward with respect to the bobbin 9 at the work position P2.

  Accordingly, since the suction port can be moved, the bottom bunch 9a is sucked and removed by strongly applying the suction flow to the bottom bunch 9a with the suction port covered on the support side end 9q of the bobbin 9. can do. Therefore, reliable removal of the bottom bunch 9a is realized.

  Further, the bobbin separation and supply device 12 of this embodiment includes a clamp mechanism 93 and an air blast nozzle 55. The clamp mechanism 93 holds the unwinding side end portion of the bobbin 9 at the work position P2. The air blast nozzle 55 is disposed in the vicinity of the suction port inside the cylindrical body 52 and injects air toward the downstream side of the suction flow.

  Thereby, the bottom bunch 9a can be reliably unwound by blowing air from the air blast nozzle 55. Further, since the clamping mechanism 93 holds the unwinding side end portion 9p of the bobbin 9 during the removal operation of the bottom bunch 9a, the removal operation of the bottom bunch 9a can be performed smoothly while the bobbin 9 is stabilized (the bobbin 9 itself). Will not be clogged by suction).

  In the bobbin separation and supply device 12 of the present embodiment, the bobbin separation unit 24 that individually separates the plurality of inserted bobbins 9 is configured to supply the bobbins 9 individually.

  As a result, the plurality of bobbins 9 loaded can be separated and placed on the transport tray 21 while removing the bottom bunch 9a. As a result, the work in the post process can be simplified. Further, since there is no thread drawing, the yarn is not entangled with the transport tray 21.

  Further, in the bobbin separation and supply device 12 of the present embodiment, the bobbin separation unit 24 includes a bobbin input unit 22 and a bobbin extraction unit 23. A plurality of bobbins 9 are input to the bobbin input portion 22. The bobbin take-out unit 23 takes out the bobbin 9 from the bobbin group put into the bobbin input unit 22. The bobbin take-out unit 23 separates the bobbin 9 while conveying the bobbin 9 substantially vertically upward with respect to the installation surface of the bobbin take-out unit 23.

  Thereby, in the bobbin extraction part 23, the bobbin 9 is separated while being conveyed substantially vertically upward. Therefore, the installation area required for separating the bobbin 9 can be reduced.

  Further, the bobbin separation and supply device 12 of the present embodiment includes an ascending path that conveys the bobbin 9 upward and a descending path that conveys the bobbin 9 downward. A bobbin take-out part 23 is arranged in the ascending path. A bunch removing unit 72 and a tray mounting unit 73 are arranged on the descending path.

  As a result, a rational layout is realized in which the bobbin 9 is separated while being conveyed upward, and the bunch is removed and placed on the conveyance tray 21 while being conveyed downward. Further, since the bunch removing unit 72 and the tray mounting unit 73 are stacked in the vertical direction in the descending path, the entire installation area can be greatly reduced.

  In the bobbin separating and supplying apparatus 12 of the present embodiment, the bobbin 9 is sent to the bunch removing unit 72 after detecting the direction of the bobbin 9 and aligning it in a certain direction on the upstream side of the bunch removing unit 72. A bobbin direction aligning portion 71 is provided.

  Thereby, the direction of the bobbin 9 is detected in the bobbin direction aligning unit 71, and the bobbin 9 always directed in a certain direction is supplied to the bunch removing unit 72. Therefore, the removal process in the bunch removal unit 72 can be simplified. Specifically, since the bottom bunch 9a is always supplied to the side where the suction mechanism 51 for removing the bottom bunch 9a is disposed, it is not necessary to adjust the direction of the bobbin 9 by the bunch removing unit 72.

  The automatic winder system 10 according to the present embodiment includes the bobbin separation and supply device 12 described above, an automatic winder, and a bobbin preparation device 17. The automatic winder winds the yarn from the bobbin 9 to form a package. The bobbin preparation device 17 prepares the automatic winder to be in a state where it can process the bobbin while conveying the conveyance tray 21 supplied with the bobbin 9 by the bobbin separation and supply device 12 to the automatic winder. The bobbin preparation device 17 is provided with a bobbin transport path 20 for transporting the transport tray 21 supplied with the bobbin 9 from the bobbin separation and supply device 12 to the automatic winder. The bobbin conveyance path 20 is provided with a spout device 18 for processing the yarn end on the end side when the yarn is wound around the bobbin 9.

  Thereby, since the bunch removal part is provided in the bobbin separation supply apparatus 12 side, it is not necessary to provide a bottom bunch removal part in the bobbin preparation device. Accordingly, it is possible to reduce the size of the apparatus.

  Next, a modification of the above embodiment will be described. FIG. 11 is a schematic plan view showing the configuration of the bobbin preparation device 17 in the bobbin supply system according to the modification. In the description of this modification, the same or similar members as those in the above-described embodiment may be denoted by the same reference numerals in the drawings, and description thereof may be omitted.

  In the present modification, the bobbin preparation device 17 is provided with a second bunch removing unit 74 in addition to the mouthing device 18. As this 2nd bunch removal part 74, the conventional thing currently disclosed by the said patent document 2 can be used, for example.

  In this modified example, the bunch removal process is performed at two locations of the bunch removal unit 72 and the second bunch removal unit 74 while the bobbin 9 is transported along an appropriate route. Therefore, the success rate of removal of the bottom bunch 9a is improved as compared with the conventional configuration in which the bunch removal operation is performed only by the bunch removal device provided in the bobbin preparation device, and the bottom bunch is removed in the winding operation by the winder unit. It is possible to avoid problems due to not being performed.

  As described above, in the automatic winder system 10 according to this modification, the bobbin preparation device 17 is provided with the second bunch removing unit 74 that removes the bottom bunch 9a.

  As a result, the bottom bunch 9a of the bobbin 9 can be reliably removed by the two bunch removal processes including the process by the bunch removal unit 72 and the process by the second bunch removal unit 74 in the bobbin separation and supply device 12. it can.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  As a drive unit for driving the cylindrical body 52, another drive source, for example, a stepping motor can be employed instead of the air cylinder 54 as in the above embodiment. When using a stepping motor, it is preferable at the point which can control the moving distance and moving speed of the cylinder 52 easily. Further, for example, even when the cylindrical body 52 collides with the bobbin 9 clogged in the bobbin housing space 94, the stepping motor steps out, which is advantageous in that the motor and the apparatus can be prevented from being damaged.

  The bunch removing unit 72 having the configuration shown in FIGS. 6 to 8 is not limited to the vertical conveyor type bobbin extracting unit 23, and may be applied to, for example, a parts feeder type bobbin extracting unit.

  Further, the configuration of the present invention can be applied to a so-called link type automatic winder having a configuration in which a chute is present when moving from a spinning machine to an automatic winder as disclosed in JP-A-62-74886. it can.
