Description

  The present invention relates to a bobbin transport system that transports bobbins. Specifically, the present invention relates to a configuration for selecting a tray on which an actual bobbin and an empty bobbin are placed and a tray without a bobbin in a bobbin transport system between a spinning machine and a winder.

  In a bobbin transport system for a spinning winder in which a spinning machine and a winder are connected, an actual bobbin and an empty bobbin may be transported on the same transport path. In such a configuration, an empty bobbin is supplied to the spinning machine from the conveyance path, and a sorting device for sorting the winder so that an actual bobbin wound with a yarn by the spinning machine is supplied from the conveyance path, It is installed near the spinning machine and winder.

An example of a bobbin transport system that includes a sorting device for sorting an actual bobbin and an empty bobbin is disclosed in Patent Document 1.
Japanese Patent Publication No. 1-27943

  In the case of a system in which a bobbin is inserted into a tray that is transported on a belt conveyor and is transported through a transport path as disclosed in Patent Document 1, a failure of the bobbin transport system that occurs in the transport process of the transport path In some cases, the bobbin on the tray is removed from the transport path due to an accident such as hitting the operator's foot.

  If the spinning machine is of the type that performs simultaneous duffing, if the bobbin-less tray is accidentally supplied to the spinning machine, there is no bobbin for winding the yarn, so the yarn is scattered and the yarn remains supplied. The scattered yarn may wrap around other bobbins or get caught in the device. In this case, it is necessary to stop the spinning machine and remove the yarn entangled in the apparatus and the bobbin that is not used after the scattered yarn is caught, which hinders the operation of the entire apparatus. For this reason, it has been necessary for the operator to regularly check visually and remove the bobbinless tray.

  In addition, if the actual bobbin is accidentally supplied to the spinning machine, the yarn is further wound from above the actual bobbin, and the outer diameter of the yarn layer becomes excessively large, and the spinning machine, particularly the ring spinning machine, cannot be wound. Or the spinning unit may be damaged. In this regard, in Patent Document 1, the real bobbin and the empty bobbin are sorted so that the real bobbin is not erroneously sent to the spinning machine. However, there is room for improvement from the viewpoint of increasing the certainty of the selection of the actual bobbin and the empty bobbin. is there.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bobbin transport system that sorts actual bobbins, empty bobbins, and bobbinless trays to perform more reliable bobbin transport.

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 a first aspect of the present invention, in a bobbin conveying system for providing an empty bobbin to the spinning machine and supplying an actual bobbin to the winder, provided in a spinning winder in which a spinning machine and a winder are connected. The following configurations are provided. That is, the bobbin transport system includes a tray transport path for transporting a tray on which an actual bobbin or an empty bobbin is mounted, and a bobbinless tray discharge device that discharges a tray on which no bobbin is mounted from the tray transport path. A bobbin sorting device that sorts the tray on which the actual bobbin is placed and the tray on which the empty bobbin is placed. In the tray conveyance path, the bobbinless tray discharge device is located upstream of the bobbin sorting device.

  With this configuration, the bobbin-free tray discharging device upstream of the bobbin sorting device can discharge the bobbin-free tray from the tray conveyance path in advance. Therefore, it is possible to remarkably reduce the burden of monitoring work for monitoring whether the tray without the bobbin is transported on the tray transport path and the burden of removing the tray without the bobbin. In addition, since it is possible to avoid a human error such as leaving a tray without a bobbin, it is possible to reliably prevent erroneous feeding that a tray without a bobbin is supplied to a transport destination. Furthermore, since the bobbin-free tray is ejected in advance by the bobbin-free tray ejecting device, it is sufficient for the bobbin sorting device on the downstream side only to sort the actual bobbin and the empty bobbin. Therefore, the configuration of the bobbin sorting device is simplified, and the sorting accuracy of the actual bobbin and the empty bobbin is also improved.

  In the bobbin conveying system, it is preferable that the spinning machine includes an empty bobbin supply path for supplying the empty bobbin, and the bobbin sorting device is provided at an inlet of the empty bobbin supply path.

  With this configuration, it is possible to prevent the erroneous feeding of the actual bobbin to the spinning machine immediately before. As a result, it is possible to more reliably prevent the occurrence of a serious problem such as inability to wind or break the spinning machine.

  In the bobbin transport system, it is preferable that the bobbinless tray discharge device is disposed in the vicinity of the upstream side of the inlet of the empty bobbin supply path.

  With this configuration, the tray that has just passed through the bobbinless tray discharge device and has removed the bobbinless tray can be supplied to the bobbin sorting device at the entrance of the empty bobbin supply path. Therefore, it is possible to prevent the tray without the bobbin from being conveyed to the bobbin sorting device and erroneously sent to the spinning machine.

  In the bobbin conveyance system, the spinning machine is preferably a spinning machine that performs simultaneous duffing.

  That is, since the bobbin transport system is excellent in sorting accuracy as described above, it is preferable to apply it to a simultaneous doffing type spinning machine in which erroneous feeding of a tray leads to troubles such as operation stoppage.

  The bobbin transport system preferably has the following configuration. In other words, the bobbin transport system includes a tray gathering unit disposed on the upstream side of the bobbin sorting device. The bobbin sorting device includes a branch path that branches from the tray conveyance path and a bobbin sorting guide. The bobbin sorting guide is configured to push the tray toward one end of the tray conveyance path by contacting the actual bobbin when the actual bobbin is placed on the tray. The tray gathering unit is configured to bring the tray conveyed along the tray conveyance path toward the other end of the tray conveyance path. The tray conveyance path includes a direction changing unit that changes the conveyance direction of the tray on the upstream side of the bobbin sorting device. And the said tray gathering part is arrange | positioned in the part of this direction change part.

  With this configuration, before the tray is supplied to the bobbin sorting device, the tray is moved toward the other end of the tray conveyance path by the tray moving portion. Therefore, the tray on which the empty bobbin is placed passes through the other end of the tray conveyance path (without being pushed by the bobbin sorting guide). On the other hand, the tray on which the actual bobbin is placed is pushed by the bobbin sorting guide and passes through one end of the tray conveyance path. Thereby, any one of an empty bobbin and an actual bobbin can be reliably sent to the branch path side, and the sorting accuracy can be improved. In addition, since the tray gathering portion is provided in the direction changing portion, the tray is not caught by the tray gathering portion, and the tray can be conveyed downstream while smoothly approaching the road end.

  In the bobbin conveyance system, it is preferable that one end of the tray conveyance path projects to the other side, and the tray gathering portion is configured in this portion.

  With this configuration, a simple configuration of the tray gathering unit can be realized.

  The bobbin transport system is preferably configured as follows. That is, the width of the tray conveyance path on the upstream side of the direction changing unit is configured to generate a predetermined gap between the tray and the tray. The distance by which the tray is brought together by the tray gathering part is equal to or larger than the size of the gap.

  With this configuration, even when the transported tray is close to the end of one side of the tray transport path in the range of the gap, the tray approaching section can reliably approach the end of the other side of the tray transport path. it can. Accordingly, the tray moving path in the bobbin sorting device can be stabilized, and the sorting accuracy of the actual bobbin and the empty bobbin is further improved.

  The bobbin transport system is preferably configured as follows. That is, the bobbinless tray discharge device includes a tray discharge path branched from the tray conveyance path, and a tray selection guide. Then, when the bobbin is placed on the tray, the bobbinless tray discharging apparatus guides the tray to the tray conveyance path by contacting the bobbin with the tray selection guide. On the other hand, when the bobbin is not placed on the tray, the tray selection guide is passed through and conveyed to the tray discharge path.

  With this configuration, a tray without a bobbin can be discharged without adding a complicated mechanism to the tray conveyance path.

  Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing a layout of a bobbin transport system 1 according to an embodiment of the present invention.

  FIG. 1 shows a fine spinning winder to which the bobbin conveying system 1 of the present embodiment is applied. In FIG. 1, the spinning winder includes a spinning machine 11 and a winder 10.

  The bobbin conveyance system 1 includes a loop-shaped tray conveyance path 12 that connects the spinning machine 11 and the winder 10. The tray 20 that can be set with the bobbin set up can be transported along the tray transport path 12. The bobbin conveying system 1 of the present embodiment includes a tray 20 on which a bobbin (actual bobbin 24) in which a yarn is wound, and a tray 20 on which a bobbin (empty bobbin 23) in which no yarn is wound, It is configured to transport along a common tray transport path 12.

  The winder 10 and the spinning machine 11 are arranged outside the loop-shaped tray conveyance path 12. Therefore, the tray conveyance path 12 can be configured to be short, and a bobbin conveyance system having a simple configuration can be configured. In the following description, the upstream side in the transport direction of the tray 20 (actual bobbin 24 or empty bobbin 23) in the tray transport path 12 is simply referred to as “upstream side”, and the downstream side in the transport direction is simply referred to as “downstream side”. Sometimes.

  As shown in FIG. 1, the winder 10 includes a connecting portion, and is connected to the tray conveyance path 12 through the connecting portion. Similarly, the spinning machine 11 includes a connecting portion, and is connected to the tray conveyance path 12 through the connecting portion.

  The connecting portion of the winder 10 includes an actual bobbin supply path 17 for supplying an actual bobbin and an empty bobbin return path 18 for returning an empty bobbin. The actual bobbin supply path 17 and the empty bobbin return path 18 are independent paths. The connecting portion of the spinning machine 11 includes an empty bobbin supply path 15 for supplying an empty bobbin and an actual bobbin return path 16 for returning an actual bobbin. As with the winder 10, the empty bobbin supply path 15 and the actual bobbin return path 16 are independent paths.

  Although FIG. 1 shows a layout in which two spinning machines are installed, the present invention is not limited to this, and one or three or more spinning machines 11 may be installed. Each spinning machine 11 produces a yarn, and this yarn is wound around an empty bobbin 23 supplied from an empty bobbin supply path 15. The empty bobbin 23 is wound with a yarn to become an actual bobbin 24 and is returned to the tray conveying path 12 via the actual bobbin return path 16.

  Each spinning machine 11 is configured as a so-called simultaneous doffing type. In this type of spinning machine 11, a large number of empty bobbins 23 conveyed from the empty bobbin supply path 15 are arranged in a row and stocked. When a predetermined timing is reached, a large number of empty bobbins 23 are simultaneously set in the spinning machine 11. Then, wind the yarn at the same time. When the winding of the yarn is completed, all the actual bobbins 24 are doffed all at once and are delivered to the actual bobbin return path 16.

  Although the layout of FIG. 1 shows an example in which two winders 10 are installed, the present invention is not limited to this, and one or three or more winders 10 may be installed. Each winder 10 unwinds the yarn from the actual bobbin 24 supplied from the tray conveyance path 12 via the actual bobbin supply path 17 and winds it up to a predetermined package. When the actual bobbin 24 runs out of yarn and becomes an empty bobbin 23, the empty bobbin 23 is returned to the tray conveyance path 12 via the empty bobbin return path 18.

  Each of the winders 10 has a configuration in which a large number of winding units are arranged in parallel, and each winding unit is provided so as to straddle the actual bobbin supply path 17 and the empty bobbin return path 18. Each winding unit unwinds the yarn from the actual bobbin 24 supplied from the actual bobbin supply path 17 and winds it back to the package.

  A bobbin sorting device 14 for sorting the actual bobbin 24 and the empty bobbin 23 is provided at a location where the spinning bobbin 12 branches to the empty bobbin supply path 15 of each spinning machine 11 (inlet of the empty bobbin supply path 15). It has been. The bobbin sorting device 14 sorts the tray 20 of the actual bobbin 24 and the tray 20 of the empty bobbin 23 that are being conveyed on the tray conveyance path 12 so that only the tray 20 of the empty bobbin 23 is taken into the empty bobbin supply path 15. It is configured.

  In addition, a bobbinless tray discharge device 13 is installed further upstream of the bobbin sorting device 14 located on the most upstream side. The bobbinless tray discharge device 13 is configured to discharge only the tray 20 on which no bobbin is set from the tray transport path 12 to the tray collection box 44 via the tray discharge path 41.

  FIG. 2 is a cross-sectional view showing the tray 20 that is transported through the tray transport path 12 with the empty bobbin 23 set. As shown in FIG. 2, the tray 20 includes a mounting table 21 having a circular shape in plan view, a guided portion 28 having a circular shape in plan view provided in a convex shape at the center of the upper surface of the mounting table 21, and the guided portion 28. And a bobbin insertion peg 26 protruding upward from the upper surface. The mounting table 21, the guided portion 28, and the bobbin insertion peg 26 are integrally formed.

  The bobbin insertion peg 26 can be inserted into a hole formed in the bottom portion of the bobbin, so that the bobbin can be set on the tray 20. Although FIG. 2 shows a state where the empty bobbin 23 is set on the tray 20, the actual bobbin 24 can be similarly set on the tray 20 by being inserted into the bobbin insertion peg 26.

  The bobbin transport system 1 includes a guide plate 31 for defining the outline of the tray transport path 12. The guide plates 31 are installed on both sides so as to sandwich the tray conveying path 12, and the edge portions thereof are configured to be able to contact the guided portion 28 of the tray 20.

  The bobbin conveying system 1 includes a belt conveyor (conveying unit) 30 for conveying the tray 20. The belt conveyor 30 is disposed so as to widely cover the lower side of the tray conveyance path 12, and is driven in a predetermined direction. With this configuration, the tray 20 set on the tray conveyance path 12 and placed on the belt conveyor 30 is configured to guide the guided portion 28 to the edge portion of the guide plate 31 by driving the belt conveyor 30. It is conveyed while. As a result, the tray 20 can be transported downstream along the tray transport path 12.

  The interval between the edge portions of the guide plates 31 facing each other across the tray transport path 12 is set to be slightly larger than the diameter of the guided portion 28. Accordingly, an appropriate gap is formed between the guided portion 28 of the tray 20 and the edge portion of the guide plate 31, so that the tray 20 can be transported smoothly.

  Here, as described above, the tray conveyance path 12 is a common conveyance path for the actual bobbin 24 and the empty bobbin 23. Therefore, in the bobbin transport system 1 of the present embodiment, the tray 20 on which the actual bobbin 24 is placed and the tray 20 on which the empty bobbin 23 is placed are transported on the tray transport path 12 while being randomly mixed. It is also conceivable that the actual bobbin 24 or the empty bobbin 23 is detached from the tray 20 for some reason during the bobbin conveyance, and only the tray 20 is brought into a state. In consideration of this, in the bobbin transport system 1, the tray 20 with the actual bobbin 24, the tray 20 with the empty bobbin 23, and the tray 20 without the bobbin are transported on the tray transport path 12 in a randomly mixed state. It will be.

  FIG. 3 is an enlarged plan view showing the bobbin sorting device 14 and the bobbinless tray discharge device 13. As shown in FIG. 3, the bobbin sorting device 14 is provided in the vicinity of a branch point where the empty bobbin supply path 15 branches in the tray transport path 12. A bobbinless tray discharge device 13 is provided upstream of the bobbin sorting device 14 in the tray conveyance path 12.

  Next, the bobbinless tray discharge device 13 will be described in detail with reference to FIGS. 4 and 5. FIG. 4 is an enlarged plan view showing a state in which the bobbin-free tray 20 is sorted by the bobbin-free tray discharging device 13, and FIG. 5 is a perspective view showing the sorting state.

  The bobbinless tray discharge device 13 includes a tray discharge path 41 branched from the tray transport path 12, a tray selection guide 40 installed at a branch portion of the tray discharge path 41, and a tray collection box connected to the tray discharge path 41. 44.

  On the upstream side of the bobbinless tray discharge device 13, the direction of the tray conveyance path 12 coincides with the conveyance direction by the belt conveyor 30. On the other hand, the tray discharge path 41 is installed so as to branch toward the outside of the loop path formed by the tray transport path 12. Further, in the vicinity of this branching portion, the tray transport path 12 is bent so that the transport direction is slightly inclined inward of the loop path (that is, opposite to the tray discharge path 41), and again after passing through the inlet of the tray discharge path 41. It is configured to return to the original transport direction.

  As shown in FIG. 5, the tray selection guide 40 is disposed at a location where the tray discharge path 41 branches from the tray transport path 12. The tray selection guide 40 is fixed to the upper surface of the guide plate 31 and includes a guide surface 47 located above the inlet of the tray discharge path 41.

  The guide surface 47 is disposed at a position higher than the tip of the bobbin insertion peg 26 of the tray 20 conveyed on the tray conveyance path 12. Therefore, when there is no bobbin on the tray 20 (in the case of the tray 20 without a bobbin), the tray 20 does not contact the guide surface 47. On the other hand, when the actual bobbin 24 or the empty bobbin 23 is set on the tray 20, the actual bobbin 24 or the empty bobbin 23 comes into contact with the guide surface 47.

  The guide surface 47 guides the actual bobbin 24 or the empty bobbin 23 at the branch portion so as to be sent downstream along the tray transport path 12 (that is, to prevent the transition to the tray discharge path 41). Therefore, the tray 20 on which the actual bobbin 24 or the empty bobbin 23 is set is conveyed in the tray conveyance path 12 as it is downstream. On the other hand, the tray 20 without the bobbin passes under the tray sorting guide 40 and enters the tray discharge path 41 without contacting the tray sorting guide 40. Then, the tray 20 without the bobbin is conveyed through the tray discharge path 41 and discharged to the tray collection box 44.

  With the above configuration, the bobbinless tray 20 is removed in advance by the bobbinless tray discharging device 13 among the tray 20 of the actual bobbin 24, the tray 20 of the empty bobbin 23, and the tray 20 without the bobbin that are transported through the tray transport path 12. And then discharged to the bobbin sorting device 14. Therefore, the bobbin sorting device 14 on the downstream side only needs to sort the actual bobbin 24 and the empty bobbin 23.

  Next, the bobbin sorting device 14 will be described with reference to FIG. FIG. 6 is an enlarged plan view of the bobbin sorting device 14.

  The bobbin sorting device 14 includes an empty bobbin supply path 15 as a branch path that branches from the tray conveyance path 12, a bobbin sorting guide 42, and a top guide 43. The bobbin sorting guide 42 is installed immediately upstream of the location where the empty bobbin supply path 15 branches.

  In the portion immediately upstream of the location where the empty bobbin supply path 15 branches from the tray transport path 12, the tray transport path 12 is formed to be slightly wider. Further, the empty bobbin supply path 15 is formed so as to be directed to the outside of the loop path formed by the tray transport path 12 from the branched portion. In the following description of the bobbin sorting device 14, the outside of the loop path formed by the tray conveyance path 12 may be simply referred to as “outside”, and the outside of the loop path may be simply referred to as “inside”.

  Accordingly, the tray 20 that is transported along the outside (upper side in FIG. 6) of the wide portion of the tray transport path 12 enters the empty bobbin supply path 15 from the branch point and is transported through the empty bobbin supply path 15. It is sent to the spinning machine 11. On the other hand, the tray 20 that is transported on the inner end (lower side in FIG. 6) of the wide portion of the tray transport path 12 passes through the branch portion of the empty bobbin supply path 15 and is transported on the tray transport path 12 as it is. Will be.

  The bobbin sorting guide 42 is disposed on the outer road end in the wide portion of the tray conveyance path 12. The bobbin sorting guide 42 comes into contact with the yarn layer of the actual bobbin 24 when the tray 20 on which the actual bobbin 24 is set passes through the wide portion of the tray conveying path 12, and the tray 20 is in contact with the tray conveying path. 12 is provided so as to prevent passage through the outer road ends.

  As a result, the tray 20 on which the actual bobbin 24 is placed is naturally pushed by the bobbin sorting guide 42 toward the inner end of the tray conveyance path 12. Therefore, the tray 20 on which the actual bobbin 24 is placed is not introduced into the empty bobbin supply path 15 but is transported on the tray transport path 12 as it is.

  The top guide 43 is vertically provided at a position on the opposite side of the bobbin sorting guide 42 with respect to the tray conveyance path 12 (inner side of the tray conveyance path 12). The top guide 43 prevents the actual bobbin 24 from coming into an unstable posture when in contact with the bobbin sorting guide 42 and being pushed by contacting the upper end of the actual bobbin 24.

  On the other hand, when the empty bobbin 23 is set on the tray 20, the bobbin sorting guide 42 does not contact the empty bobbin 23. Accordingly, the tray 20 on which the empty bobbin 23 is placed is not pushed into the tray conveyance path 12 and passes through the outer path end. Accordingly, the tray 20 of the empty bobbin 23 is introduced into the empty bobbin supply path 15 and sent to the spinning machine 11.

  On the upstream side of the bobbin sorting device 14, the direction of the tray conveyance path 12 coincides with the conveyance direction of the belt conveyor 30. However, the tray conveying path 12 has two direction changing portions 48 and 49 on the upstream side of the bobbin sorting device 14. In the first direction changing unit 48, the tray conveyance path 12 is bent, and the direction is slightly inclined outward from the conveyance direction of the belt conveyor 30. Also in the second direction changing unit 49 downstream of the first direction changing unit 48, the tray conveyance path 12 is bent and the direction is returned to the direction coinciding with the conveying direction of the belt conveyor 30.

  And in the part of the 2nd direction change part 49, the tray gathering part 45 is provided in the road edge inside the tray conveyance path 12. FIG. Specifically, the edge of the guide plate 31 located at the inner peripheral side (inside the loop) where the tray conveyance path 12 bends in the second direction changing portion 49 is convex toward the outer peripheral side (outside the loop). The protruding portion is used as the tray gathering portion 45.

  With this configuration, the tray 20 that has passed through the two direction changing portions 48 and 49 is moved toward the end of the tray conveying path 12 by the tray moving portion 45. Accordingly, since the tray 20 is positioned at the outer end of the tray conveyance path 12 from the beginning, in the case of the tray 20 on which the empty bobbin 23 is placed, the outer path end is conveyed as it is, and the empty bobbin supply path 15 Can be smoothly supplied to the inlet.

  If the tray gathering portion 45 is not provided, the tray 20 with the empty bobbin 23 set cannot be brought close to the outer end of the tray conveying path 12 and is therefore surely sent to the empty bobbin supply path 15. Becomes difficult. In this regard, in the present embodiment, the presence of the tray gathering portion 45 enables the actual bobbin 24 and the empty bobbin 23 to be reliably selected.

  The protruding amount of the tray gathering portion 45 is obtained by subtracting the diameter of the guided portion 28 from the distance between the edges of the guide plates 31 facing each other in the tray transport path 12 on the upstream side of the second direction changing portion 49. It is configured to be equal to or larger than that. In other words, the distance by which the tray 20 is moved by the tray moving portion 45 is configured to be equal to or larger than the size of the gap between the tray transport path 12 and the guided portion 28. With this configuration, the tray 20 can be reliably brought to the end of the tray transport path 12 by the tray gathering portion 45.

  Next, with reference to FIG. 7 to FIG. 10, how the real bobbin 24 and the empty bobbin 23 are sorted using the bobbin sorting device 14 will be described. FIG. 7 is a perspective view showing a state where the actual bobbin 24 is sorted by the bobbin sorting device 14, and FIG. 8 is a cross-sectional view showing a state where the actual bobbin 24 is in contact with the bobbin sorting guide 42. FIG. 9 is a perspective view showing how the empty bobbin 23 is sorted, and FIG. 10 is a cross-sectional view showing how the empty bobbin 23 passes through the bobbin sorting guide 42. 7 and 9, the top guide 43 is not shown for easy understanding of the drawings.

  When the tray 20 on which the actual bobbin 24 is set has been transported through the tray transport path 12, the tray 20 in FIG. 7 passes through the direction changing sections 48 and 49 and is outside the tray transport path 12 by the tray abutting section 45. Pushed to the roadside. Thereafter, the actual bobbin 24 that has reached the position of the bobbin sorting guide 42 comes into contact with the bobbin sorting guide 42 as shown in FIG. As a result, as shown by a chain line arrow in FIG. 7, the tray 20 is pushed to the inner end of the tray conveyance path 12. Thus, since the travel path of the tray 20 is shifted to the inner end of the tray transport path 12, the tray 20 on which the actual bobbin 24 is placed is transported on the tray transport path 12 without being taken into the empty bobbin supply path 15. The

  On the other hand, when the tray 20 on which the empty bobbin 23 is set has been transported through the tray transport path 12, the tray 20 passes through the direction changing sections 48 and 49 in FIG. It is pushed to the roadside outside. Thereafter, the empty bobbin 23 reaches the position of the bobbin sorting guide 42. However, since the yarn is not wound around the empty bobbin 23, it does not come into contact with the bobbin sorting guide 42. As a result, as shown by a chain line arrow in FIG. 9, the tray 20 passes straight through the outer end of the tray conveyance path 12. Accordingly, the tray 20 on which the empty bobbin 23 is placed is taken into the empty bobbin supply path 15 from the branch portion and is conveyed to the spinning machine 11.

  The bobbin sorting device 14 described above is provided corresponding to each of the plurality of spinning machines 11 shown in FIG. 1, and is configured to sort the actual bobbin 24 and the empty bobbin 23.

  Further, corresponding to each of the plurality of winders 10 shown in FIG. 1, a winder bobbin sorting device 60 for selecting the actual bobbin 24 and taking it into the actual bobbin supply path 17 is provided. Although detailed description of the winder bobbin sorting device 60 is omitted, in the bobbin sorting device 14 described with reference to FIG. 6, the positional relationship of the bobbin sorting guide 42, the top guide 43, the tray gathering portion 45, and the like is reversed, and the branch path The actual bobbin supply path 17 can be used so that the actual bobbin 24 can be introduced.

  As described above, the bobbin transport system 1 of the fine spinning winder according to the present embodiment includes the tray transport path 12 for transporting the tray 20 on which the actual bobbin 24 or the empty bobbin 23 is mounted, and the bobbin.
