Description

Technical Field

[0001] One aspect of the present invention relates to a work trolley and a yarn winding machine. Background Technology

[0002] A yarn winding machine is known, comprising: a group of winding units that form a package by winding yarn onto a yarn bobbin in an arrangement direction; and a doffing device that is configured to travel along the arrangement direction of the winding units, and that retrieves the package (forming a fully wound yarn bobbin) from the winding units and supplies yarn bobbins to the winding units. For example, Japanese Patent Document 1 (Japanese Unexamined Patent Application Publication No. 5-17072) discloses a yarn winding machine that includes multiple yarn bobbin storage sections (paper bobbin supply devices) and a conveyor that transports the yarn bobbins (paper bobbins) from the multiple yarn bobbin storage sections to a doffing trolley. In this yarn winding machine, because multiple yarn bobbin storage sections are provided, different types of yarn bobbins can be supplied accordingly to each winding unit. Summary of the Invention

[0003] In yarn winding machines, to meet the demand for producing multiple types of packages, as mentioned above, different types of yarn bobbins need to be supplied to each winding unit. In this case, the doffing trolley needs to store multiple types of yarn bobbins in advance. Furthermore, regardless of the type, when there are many winding units and / or when the yarn is wound at high speed within a winding unit, the frequency of yarn bobbin supply relative to the winding unit increases. In this case, the doffing trolley needs to store a large number of yarn bobbins in advance. Thus, the doffing trolley is required to handle a variety of configurations.

[0004] Therefore, one object of the present invention is to provide a work trolley and yarn winding machine capable of handling a wide variety of shapes.

[0005] One aspect of the present invention provides a work trolley capable of traveling along an arrangement direction of a plurality of winding units and supplying yarn tubes to the winding units. The work trolley includes: a yarn magazine for storing a plurality of yarn tubes; and an operation unit for delivering the yarn tubes stored in the yarn magazine to the winding units. The yarn magazine has a plurality of storage sections for storing a plurality of yarn tubes. Each of the storage sections has an inlet for the yarn tubes to pass through when they are introduced into the storage section, and an outlet for the yarn tubes to pass through when they are delivered from the storage section to the operation unit.

[0006] In one aspect of the present invention, the yarn storage unit has multiple storage sections, each having an inlet for the yarn tube to pass through when it is introduced into the storage section and an outlet for the yarn tube to pass through when it is delivered from the storage section to the operation section. Thus, the multiple storage sections independently store the yarn tubes. For example, different types of yarn tubes can be stored in each of the multiple storage sections. Therefore, the work trolley can handle multiple types. Furthermore, even when the types of yarn tubes stored in each storage section are the same, the number of yarn tubes that can be stored in each of the multiple storage sections can be increased as a whole. Therefore, the work trolley can handle situations where the frequency of yarn tube supply to the winding unit is high. In this way, the work trolley can handle a wide variety of configurations.

[0007] In one aspect of the present invention, the work trolley may have two or more but no more than four storage sections. This structure avoids the need for a large work trolley.

[0008] In one aspect of the work trolley of the present invention, a control unit may be included, which determines which of a plurality of storage units to supply the yarn bobbin to the operating unit after the work trolley reaches the working position for the winding unit. In this configuration, since the storage unit for supplying the yarn bobbin to the operating unit is determined after the work trolley reaches the working position, the appropriate yarn bobbin can be reliably delivered to the winding unit. For example, if the operating unit retrieves the yarn bobbin from the storage unit at an earlier stage, and the type of yarn bobbin actually required changes after the retrieval, the operating unit may need to perform actions such as temporarily discharging the retrieved yarn bobbin. Alternatively, the work trolley may remain idle until it is possible to supply the retrieved yarn bobbin to a particular winding unit. In the work trolley of one aspect of the present invention, since such actions can be avoided, the appropriate yarn bobbin can be delivered to the winding unit efficiently.

[0009] In one aspect of the invention, the work trolley may also have multiple storage sections that store multiple yarn tubes stacked with their axes aligned along the arrangement direction, and these multiple storage sections are arranged side-by-side in a horizontal direction when viewed along the arrangement direction. This structure allows for a compact configuration of the work trolley.

[0010] In one aspect of the present invention, the work trolley may also include a distribution mechanism that distributes the yarn tubes supplied to the yarn magazine to the inlet of one of a plurality of storage sections. In this configuration, since the distribution mechanism of the work trolley itself can distribute the yarn tubes supplied to the yarn magazine to one of the plurality of storage sections, the distribution operation can be performed close to the storage section. As a result, the speed of the yarn tube distribution operation can be increased, and the processing capacity of the work trolley can be improved.

[0011] In one aspect of the work trolley of the present invention, a plurality of storage sections may include a first storage section and a second storage section, which are arranged side by side in a horizontal direction when viewed along the arrangement direction. The dispensing mechanism has: a rotating shaft disposed between the first and second storage sections and extending along the arrangement direction; and a dispensing section connected to the rotating shaft and rotating about the rotating shaft. In this structure, by oscillating the dispensing section, the yarn tube can be dispensed to the first or second storage section. Since the dispensing mechanism has a simple structure with a rotating shaft and a dispensing section, the large size of the work trolley can also be avoided.

[0012] In one aspect of the work trolley of the invention, the distribution section may have a generally V-shaped form when viewed along the axial direction of the rotation axis. In this configuration, the distribution section is able to stably distribute yarn tubes to each storage section.

[0013] In one aspect of the work trolley of the present invention, the dispensing mechanism may have a drive unit that moves the dispensing section between a first position and a second position. The dispensing section has a guide section for guiding the yarn tube and a restricting section for restricting the movement of the yarn tube. When the yarn tube is introduced into the first storage section, the drive unit positions the dispensing section in the first position, and the restricting section restricts the movement of the yarn tube towards the second storage section, thereby dispensing the yarn tube into the first storage section. When the yarn tube is introduced into the second storage section, after the drive unit positions the dispensing section in the second position and the guide section guides the yarn tube towards the second storage section, the drive unit positions the dispensing section in the first position, thereby dispensing the yarn tube into the second storage section. In this structure, by using the drive unit to move the dispensing section between the first and second positions, the yarn tube can be accurately dispensed into the first or second storage section.

[0014] In one aspect of the present invention, the work trolley may also include: a housing housing containing a yarn magazine and an operating section; and an auxiliary yarn magazine disposed on the outer side of the housing for storing yarn tubes. This structure increases the number of yarn tubes that the work trolley can store. For example, the operator can move yarn tubes stored in the auxiliary yarn magazine to the storage section at any time.

[0015] One aspect of the present invention is a yarn winding machine comprising: a plurality of winding units arranged in an arrangement direction for winding yarn onto a yarn tube to form a package; the aforementioned work trolley; and a yarn tube supply device having a plurality of storage mechanisms for storing a plurality of yarn tubes, a delivery mechanism for supplying yarn tubes to the work trolley, and a conveying device for transferring yarn tubes between the plurality of storage mechanisms and the delivery mechanism.

[0016] In one aspect of the yarn winding machine of the present invention, the above-described work trolley is provided. Therefore, the yarn winding machine can handle a wide variety of configurations.

[0017] In one aspect of the yarn winding machine of the present invention, the yarn tube supply device may be arranged in a second region adjacent in the arrangement direction to the first region in which the plurality of winding units are arranged, and the yarn tube is supplied from the yarn tube supply device to the work trolley at a supply position set in the second region.

[0018] In conventional yarn winding machines, the transport of yarn bobbins via a conveyor (conveyor belt) arranged along the winding unit's orientation presents a risk that bobbins may fall off the conveyor for various reasons during transport, or that unintentional bobbins may get mixed into the conveyor. Furthermore, there is a situation where operators must simultaneously replenish bobbins at the bobbin storage area and monitor the conveyor's transport status, increasing the operator's workload.

[0019] In a yarn winding machine according to one aspect of the present invention, since the position of the conveying device for conveying the yarn tube is limited to a second region, the conveying path can be shortened compared to conventional conveying devices in which the conveying path extends along a plurality of winding units arranged in the arrangement direction.

[0020] In one aspect of the yarn winding machine of the present invention, the yarn bobbin supply device may have two or more but no more than four storage mechanisms. Furthermore, in another aspect of the yarn winding machine of the present invention, the yarn bobbin supply device may have two storage mechanisms. This avoids the need for a large-scale yarn bobbin supply device, and allows the yarn bobbin supply device to store an appropriate number of different types of yarn bobbins in advance for the work trolley.

[0021] In one aspect of the yarn winding machine of the present invention, the yarn tube supply device may also include a conveying device that transports the yarn tube between multiple storage mechanisms and a delivery mechanism. In this configuration, the conveying device is shared by multiple storage mechanisms, thus avoiding the need for a large-scale yarn tube supply device, and the yarn tube supply device can supply yarn tubes from multiple storage mechanisms to a single work trolley using a simple structure.

[0022] In one aspect of the yarn winding machine of the present invention, the yarn tube supply device may also include a take-out mechanism for removing the yarn tube from a storage mechanism. The storage mechanism has an annular strip member and a drive unit. The annular strip member has multiple holding portions capable of holding the yarn tubes one by one. The drive unit cyclically drives the strip member. A take-out position based on the take-out mechanism is set along a portion of the movement path of the holding portions implemented based on the cyclic drive. The take-out mechanism has a take-out member capable of removing the yarn tube from all take-out positions set in each of the multiple storage mechanisms. In this structure, the take-out mechanism is shared by multiple storage mechanisms, thus avoiding the need for a large-scale yarn tube supply device, and the yarn tube supply device can remove the yarn tube from multiple storage mechanisms using a simple structure.

[0023] In one aspect of the yarn winding machine of the present invention, multiple storage mechanisms may be arranged inside a single housing. In this configuration, for example, the conveying device and the delivery mechanism can also be arranged inside the same housing, simplifying the overall structure of the yarn winding machine.

[0024] In one aspect of the yarn winding machine of the present invention, a control device for controlling the yarn bobbin supply device is further included. The control device is configured to switch between a single-yarn-type mode in which the yarn bobbin supply device operates when multiple storage mechanisms each store yarn bobbins of the same type, and a multi-yarn-type mode in which the yarn bobbin supply device operates when multiple storage mechanisms each store yarn bobbins of different types. In this configuration, the yarn bobbin supply device can perform different optimal operations when multiple storage mechanisms store yarn bobbins of the same type, and when multiple storage mechanisms each store yarn bobbins of different types.

[0025] In one aspect of the yarn winding machine of the present invention, the control device may control the yarn bobbin supply device such that, in a single-yarn-type mode, one type of yarn bobbin is supplied to each of the multiple storage sections of the yarn magazine, and in a multi-variety mode, different types of yarn bobbins are supplied to each of the multiple storage sections. In this configuration, the appropriate yarn bobbin corresponding to the set mode can be supplied to the work trolley.

[0026] In one aspect of the yarn winding machine of the present invention, the control device controls the yarn tube supply device such that multiple yarn tubes are supplied in one feeding action of the feeding mechanism in a single-yarn-type mode, and one yarn tube is supplied in one feeding action of the feeding mechanism in a multi-yarn-type mode. In this configuration, in the single-yarn-type mode, multiple yarn tubes can be efficiently gathered together and supplied to the work trolley; in the multi-yarn-type mode, yarn tubes can be flexibly supplied to the various storage sections of the yarn magazine of the work trolley.

[0027] In one aspect of the yarn winding machine of the present invention, the feeding mechanism may have multiple discharge sections for discharging yarn tubes to the yarn magazine of the work trolley, with each discharge section discharging yarn tubes to a storage section. In this configuration, yarn tubes can be appropriately supplied to multiple storage sections of the work trolley.

[0028] In one aspect of the yarn winding machine of the present invention, the feeding mechanism may have a discharge section arranged such that it can be moved to each of a plurality of storage sections on the work trolley. In this configuration, yarn tubes can be flexibly supplied to the plurality of storage sections on the work trolley using a single discharge section.

[0029] In a yarn winding machine according to one aspect of the invention, at least one of a plurality of storage sections configured as a work trolley is capable of receiving yarn tubes supplied from sources other than the delivery mechanism. In this configuration, for example, the operator can supply yarn tubes to the storage section, so that the work trolley can receive yarn tube replenishment even without moving to the yarn tube supply device.

[0030] According to one aspect of the invention, the work trolley and yarn winding machine can handle a wide variety of shapes. Attached Figure Description

[0045] Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, the same reference numerals are used to label the same or equivalent parts in each drawing, and repeated descriptions are omitted. The scale of the drawings may not necessarily match the structure described. Additionally, terms indicating directions such as "up," "down," "left," "right," "front," and "back" in the description are used for convenience based on the states shown in the drawings.

[0046] like Figure 1 and Figure 2 As shown, the spinning machine (yarn winding machine) 1 includes multiple spinning units (winding units) 2, a yarn receiving trolley 3, a yarn doffing trolley (operating trolley) 4, a first end frame 5A, a second end frame 5B, a yarn tube storage section (yarn tube supply device) 60, and a conveying device (package conveyor) 80. The multiple spinning units 2 are arranged in the orientation direction (left-right direction, longitudinal direction of the spinning machine 1). Each spinning unit 2 generates yarn Y and winds it into a package P.

[0047] The first end frame 5A houses a collection device for recovering fiber scraps and yarn scraps generated in the spinning unit 2. The first end frame 5A is arranged in the direction in which the multiple spinning units 2 are arranged (…). Figure 1 and Figure 2 The second end frame 5B is located at one end (in the left-right direction). An air supply unit is housed in the second end frame 5B, which regulates the air pressure of compressed air supplied to the spinning machine 1 and supplies air to various parts of the spinning machine 1. The second end frame 5B may also house drive motors or similar devices for supplying power to various parts of the spinning units 2. The second end frame 5B is positioned at the other end in the direction in which the multiple spinning units 2 are arranged. The second end frame 5B is equipped with a machine control device (control unit) 5C, a display screen 5D, and input keys 5E.

[0048] The machine control device 5C centrally manages and controls all parts of the spinning machine 1. The display screen 5D can display information related to the settings and / or status of the spinning unit 2. The operator can perform setting operations for the spinning unit 2 by using the input key 5E. In this embodiment, the machine control device 5C controls various operations in the yarn tube storage unit 60. The various operations in the yarn tube storage unit 60 will be described in detail later.

[0049] In this embodiment, in the spinning machine 1, yarns Y of different types can be generated in multiple spinning units 2. For example, a first type of yarn Y can be generated in some of the spinning units 2, and a second type of yarn Y, different from the first type, can be generated in some of the spinning units 2. The yarn type can be set by the operator using the input key 5E of the machine control device 5C. Yarn type refers to, for example, the count of yarn Y. Alternatively, yarn type can also refer to the type of raw material of yarn Y. Examples of yarn types are not limited to these examples. Different types of yarn Y refer to yarns Y with different states.

[0050] like Figure 3 As shown, each spinning unit 2, in the direction of yarn travel Y, sequentially includes, from the upstream side, a drafting device 6, an air spinning device 7, a yarn monitoring device 8, a tension sensor 9, a yarn retention device 11, a waxing device 12, and a winding device 13. A unit controller 10 is provided for a predetermined number (one or more) of spinning units 2 and controls the operation of the spinning units 2.

[0051] The drafting device 6 drafts the yarn S. The air-spinning device 7 uses a swirling airflow to twist the fiber bundle F generated by the drafted yarn S through the drafting device 6 to produce yarn Y. The yarn holding device 11 holds the yarn Y between the air-spinning device 7 and the winding device 13, eliminating slack in the yarn Y. The waxing device 12 applies wax to the yarn Y between the yarn holding device 11 and the winding device 13. The winding device 13 winds the yarn Y onto the yarn tube B to form a package P. In the following description, "yarn tube B" may be referred to as "first yarn tube B1" or "second yarn tube B2".

[0052] The yarn monitoring device 8 monitors the information of the traveling yarn Y between the air spinning device 7 and the yarn holding device 11, and detects the presence of yarn defects based on the monitored information. If a yarn defect is detected, the yarn monitoring device 8 sends a yarn defect detection signal to the unit controller 10. The tension sensor 9 measures the tension of the traveling yarn Y between the air spinning device 7 and the yarn holding device 11, and sends a tension measurement signal to the unit controller 10. If the unit controller 10 determines that an abnormality has occurred based on the detection results of the yarn monitoring device 8 and / or the tension sensor 9, it cuts the yarn Y in the spinning unit 2.

[0053] The winding device 13 has a rocker arm 21, a winding drum 22, and a traverse guide 23. The rocker arm 21 rotatably supports the yarn tube B. The rocker arm 21 is oscillatingly supported by a support shaft 24, so that the surface of the yarn tube B or the surface of the package P contacts the surface of the winding drum 22 with appropriate pressure. The traverse guide 23 of each spinning unit 2 is provided on a shaft (not shown) shared by multiple spinning units 2.

[0054] Spinning unit 2 outputs a request signal when package P is fully wound. When a specified amount (length) of yarn Y is wound onto yarn bobbin B, spinning unit 2 determines that package P is fully wound and outputs a request signal. Alternatively, spinning unit 2 may output a request signal before a specified time has elapsed before package P becomes fully wound.

[0055] When yarn Y is cut or breaks in a spinning unit 2 for some reason, the yarn-getting carriage 3 performs a yarn-getting operation in that spinning unit 2. The yarn-getting carriage 3 travels on the travel path R1. The travel path R1 extends along the arrangement direction of the multiple spinning units 2.

[0056] The yarn splicing trolley 3 includes a suction tube 31, a yarn splicing device 32, and a suction nozzle 33. The suction tube 31 is rotatably supported, capturing yarn Y from the air spinning device 7 and guiding it to the yarn splicing device 32. The suction nozzle 33 is rotatably supported, capturing yarn Y from the winding device 13 and guiding it to the yarn splicing device 32. The yarn splicing device 32 splices the guided yarns Y together. The yarn splicing device 32 is a splicer using compressed air or a knotter that mechanically connects the yarns Y. The spinning unit 2 can also splice yarn using a piecing mechanism, that is, the yarn Y from the package P is reversed to the air spinning device 7 or reversed to a position upstream of the air spinning device 7, and the drafting action based on the drafting device 6 and the spinning action based on the air spinning device 7 are started, thereby splicing the yarn Y.

[0057] When the yarn doffing trolley 4 is fully wound in a spinning unit 2, it performs a discharging action to discharge the yarn p and a yarn bobbin placement action to install a new yarn bobbin B onto the rocker arm 21 of the spinning unit 2 to prepare for winding the yarn Y. If the yarn p is fully wound in a spinning unit 2, the yarn doffing trolley 4, according to the control signal from the machine control device 5C, travels along the travel path R2 to a spinning unit 2 and stops, performing both the discharging action and the yarn bobbin placement action (doffing operation).

[0058] The travel path R2 extends along the arrangement direction of the plurality of spinning units 2 (parallel to the travel path R1). The travel path R2 extends to the second region A2. On the front side of the bobbin storage section 60, a supply position SP is provided for the doffing trolley 4 to receive the bobbin B from the bobbin storage section 60. The doffing trolley 4 can travel on the travel path R2 and stop at the supply position SP.

[0059] The doffing trolley 4 has a housing 40, a yarn magazine 41, a yarn tube mounting mechanism (operating unit) 42, a rocker arm 43, a suction pipe 44, and spare yarn magazines 45A and 45B (see reference). Figure 1 and Figure 2The yarn magazine 41, yarn tube mounting mechanism 42, rocker arm 43, suction tube 44, and control unit 46 are housed in the housing 40. Spare yarn magazines (auxiliary yarn magazines) 45A and 45B are disposed on the outer side of the housing 40.

[0060] The yarn storage chamber 41 stores yarn tubes B supplied from the yarn tube storage section 60. The yarn storage chamber 41 can store various types of yarn tubes. In this embodiment, the yarn storage chamber 41 stores a first yarn tube B1 and a second yarn tube B2. The first yarn tube B1 and the second yarn tube B2 are of different types. For example, the first yarn tube B1 and the second yarn tube B2 are different colors. The first yarn tube B1 is, for example, red. The second yarn tube B2 is, for example, blue. That is, the first yarn tube B1 and the second yarn tube B2 can be distinguished by color. However, the first yarn tube B1 and the second yarn tube B2 may also be the same color but different in material and / or shape. In this embodiment, the first yarn tube B1 is, for example, supplied to the spinning unit 2 that generates yarn Y of a first type of yarn. The second yarn tube B2 is, for example, supplied to the spinning unit 2 that generates yarn Y of a second type of yarn.

[0061] like Figure 3 and Figure 4 As shown, the yarn storage compartment 41 has a first storage section 41A for storing the first yarn tube B1 and a second storage section 41B for storing the second yarn tube B2. The first storage section 41A and the second storage section 41B independently store either the first yarn tube B1 or the second yarn tube B2. The first storage section 41A and the second storage section 41B are arranged side by side. Specifically, the first storage section 41A and the second storage section 41B are arranged side by side in the front-back direction of the doffing carriage 4 (which is horizontal and orthogonal to the arrangement direction when viewed along the arrangement direction (left-right direction) of the spinning unit 2). Thus, in the yarn storage compartment 41, the first yarn tube B1 and the second yarn tube B2 are stored in two rows in the front-back direction.

[0062] The first storage unit 41A stores the first yarn tube B1 such that, when viewed from the traveling direction (left-right direction) of the doffing trolley 4, the axis of the first yarn tube B1 is along the traveling direction. The first storage unit 41A stores multiple first yarn tubes B1 stacked in the vertical direction (vertical direction, height direction). Figure 4 As shown, the first storage section 41A has an inlet section 41Aa and an outlet section 41Ab. The inlet section 41Aa is located at the upper part of the first storage section 41A. The inlet section 41Aa is the portion through which the first yarn tube B1 passes when it is introduced into the first storage section 41A. The first yarn tube B1 is introduced into the first storage section 41A via the inlet section 41Aa. The outlet section 41Ab is located at the lower part of the first storage section 41A. The outlet section 41Ab is the portion through which the first yarn tube B1 passes when it is delivered (transferred) from the first storage section 41A to the yarn tube mounting mechanism 42. The first yarn tube B1 is delivered from the first storage section 41A to the yarn tube mounting mechanism 42 via the outlet section 41Ab.

[0063] like Figure 3 As shown, a first supply mechanism 47A is provided in the first storage section 41A to supply the first yarn tubes B1 to the yarn tube mounting mechanism 42. The first supply mechanism 47A is located at the lower end of the first storage section 41A. The first supply mechanism 47A is composed of a shutter and a cylinder, etc. The first supply mechanism 47A supplies the first yarn tubes B1 to the yarn tube mounting mechanism 42 one by one. The operation of the first supply mechanism 47A is controlled by the control unit 46.

[0064] The second storage unit 41B stores the second yarn tube B2 in such a way that, when viewed from the traveling direction of the doffing trolley 4, the axis of the second yarn tube B2 is along the traveling direction. The second storage unit 41B stores multiple second yarn tubes B2 stacked vertically. For example... Figure 4 As shown, the second storage section 41B has an inlet section 41Ba and an outlet section 41Bb. The inlet section 41Ba is located at the upper part of the second storage section 41B. The inlet section 41Ba is the portion through which the second yarn tube B2 passes when it is introduced into the second storage section 41B. The second yarn tube B2 is introduced into the second storage section 41B via the inlet section 41Ba. The outlet section 41Bb is located at the lower part of the second storage section 41B. The outlet section 41Bb is the portion through which the second yarn tube B2 passes when it is delivered from the second storage section 41B to the yarn tube mounting mechanism 42. The second yarn tube B2 is delivered from the second storage section 41B to the yarn tube mounting mechanism 42 via the outlet section 41Bb.

[0065] like Figure 3 As shown, the second storage section 41B is provided with a second supply mechanism 47B that supplies the second yarn tubes B2 to the yarn tube mounting mechanism 42. The second supply mechanism 47B is located at the lower end of the second storage section 41B. The second supply mechanism 47B is composed of a gate and a cylinder, etc. The second supply mechanism 47B supplies the second yarn tubes B2 to the yarn tube mounting mechanism 42 one by one. The operation of the second supply mechanism 47B is controlled by the control unit 46.

[0066] The number of first yarn tubes B1 stored in the first storage section 41A and the number of second yarn tubes B2 stored in the second storage section 41B (hereinafter referred to as "storage count") can be appropriately set. In this embodiment, the first storage section 41A can store four first yarn tubes B1, and the second storage section 41B can store four second yarn tubes B2. However, the storage count can also be four or more (for example, five or six). In addition, the storage counts of the first storage section 41A and the second storage section 41B can also be different.

[0067] The yarn storage compartment 41 can also store a yarn tube B. A second yarn tube B2 can be stored in the first storage section 41A, and a first yarn tube B1 can be stored in the second storage section 41B. In this structure, yarn tubes B can be supplied to the yarn tube mounting mechanism 42 alternately from the first storage section 41A and the second storage section 41B. Alternatively, if the yarn tubes B in one of the storage sections 41A and 41B are exhausted, yarn tubes B can be supplied from the other storage section.

[0068] The yarn tube installation mechanism 42 supplies yarn tube B to the rocker arm 21. The yarn tube installation mechanism 42 receives yarn tube B from the first storage section 41A or the second storage section 41B and delivers yarn tube B to the rocker arm 21.

[0069] The suction tube 44 captures the yarn Y delivered from the air spinning device 7 by using the suction part, and guides the captured yarn Y to the winding device 13. The yarn tube B and the yarn Y can be guided to the winding device 13 simultaneously, or the yarn tube B can be supplied to the winding device 13 first and then the yarn Y can be guided.

[0070] The cradle operating arm 43 is used to open the cradle arm 21 to remove the fully wound roll P from the winding device 13, or to close the cradle arm 21 to install a new yarn tube B. If the cradle arm 21 is opened via the cradle operating arm 43, the roll P is removed from the cradle arm 21, such as... Figure 3 As shown, the yarn is discharged to the conveying device 80. The discharge direction of the yarn package P from the spinning unit 2 is from back to front. The doffing trolley 4 may also be equipped with a guiding device that guides the yarn package P from the cradle arm 21 to the conveying device 80 while in contact with the yarn package P.

[0071] Multiple yarn tubes B can be stored in spare yarn storage units 45A and 45B. For example... Figure 1 and Figure 2 As shown, spare yarn pouches 45A and 45B are disposed on the outer surface of the housing 40. Spare yarn pouch 45A is disposed, for example, on the left side of the housing 40. Spare yarn pouch 45B is disposed, for example, on the right side of the housing 40. Spare yarn pouches 45A and 45B can be disposed at the same height or at different heights. Alternatively, spare yarn pouches 45A and 45B can also be disposed on other outer surfaces of the housing 40. Only one of spare yarn pouches 45A and 45B may be provided, or a third spare yarn pouch may be provided.

[0072] The supply (replenishment) of yarn tube B to spare yarn magazines 45A and 45B is performed by the operator, for example. The operator can supply yarn tube B stored in spare yarn magazines 45A and 45B to the yarn magazine 41 (first storage section 41A and second storage section 41B) of the doffing trolley 4 at appropriate times.

[0073] like Figure 3 As shown, the control unit 46 controls the operation of the doffing carriage 4. The control unit 46 acquires the position information of the doffing carriage 4 itself and outputs it to the machine control device 5C. Specifically, the control unit 46 sends a signal to any spinning unit 2 requesting position information indicating the position of that spinning unit 2. The spinning unit 2 sends its position information to the doffing carriage 4 according to the request from the doffing carriage 4. If the control unit 46 receives the position information, it acquires the current reference position information of the doffing carriage 4 itself. The doffing carriage 4 has a detection unit (e.g., Hall element, optical sensor) that detects the detectors (e.g., magnets, reflectors, etc.) provided in each of the multiple spinning units 2. The multiple spinning units 2 are arranged at fixed intervals in the arrangement direction. Therefore, if the detection unit of the doffing carriage 4 detects one detector and then another detector, the doffing carriage 4 moves a fixed distance. The control unit 46 acquires the current position information of the doffing carriage 4 itself based on the reference position information and the detection results of the detection unit (fixed distance × number of detections). The control unit 46 outputs the current position information to the machine control device 5C.

[0074] The control unit 46 determines which of the first storage units 41A and the second storage unit 41B to supply yarn bobbins B to the spinning unit 2, and supplies yarn bobbins B from the yarn magazine 41 to the yarn bobbin mounting mechanism 42. During the travel of the doffing trolley 4, the control unit 46 determines which of the first storage units 41A and the second storage unit 41B to supply yarn bobbins B to the yarn bobbin mounting mechanism 42. More specifically, if the control unit 46 receives a control signal from the machine control device 5C, it determines, based on information regarding the yarn type contained in the control signal, during the travel of the doffing trolley 4 which of the first storage units 41A and the second storage unit 41B to supply yarn bobbins B to the spinning unit 2. Based on the determined first storage unit 41A or second storage unit 41B, the control unit 46 controls the first supply mechanism 47A or the second supply mechanism 47B to supply yarn bobbins B to the yarn bobbin mounting mechanism 42 in a manner that allows the yarn bobbins B to be supplied from either the first storage unit 41A or the second storage unit 41B.

[0075] The control unit 46 can also determine, after the doffing carriage 4 reaches the working position for the spinning unit 2 (when the doffing carriage 4 stops at the working position), which of the first storage unit 41A and the second storage unit 41B to supply yarn tube B to the yarn tube mounting mechanism 42. If the control unit 46 receives a control signal from the machine control device 5C, it determines, after the doffing carriage 4 reaches the working position, which of the first storage unit 41A and the second storage unit 41B to supply yarn tube B to the spinning unit 2 based on the information about the yarn type contained in the control signal. Based on the determined first storage unit 41A or second storage unit 41B, the control unit 46 controls the first supply mechanism 47A or the second supply mechanism 47B to supply yarn tube B to the yarn tube mounting mechanism 42 from the first storage unit 41A or the second storage unit 41B.

[0076] like Figure 1 and Figure 2 As shown, the yarn tube storage section 60 is disposed at one end of the arrangement direction of the plurality of spinning units 2 (the end where the first end frame 5A is disposed). More specifically, the yarn tube storage section 60 is disposed in a second region A2 adjacent to the right side of the first region A1 where the plurality of spinning units 2 are arranged in the arrangement direction (left-right direction). The supply of yarn tubes B from the yarn tube storage section 60 to the doffing trolley 4 is performed at the supply position SP set in the second region A2.

[0077] The yarn tube storage section 60 includes multiple storage mechanisms 61, a retrieval mechanism 63, a direction conversion mechanism 65, a conveying device 67, and a delivery mechanism 70. In this embodiment, the yarn tube B is configured as a bobbin. When viewed from the front, the yarn tube B is formed into an end-expanding shape that widens axially from one end to the other. Hereinafter, one end will be referred to as the small-diameter end, and the other end as the large-diameter end.

[0078] The storage mechanism 61 is a mechanism for storing multiple yarn tubes B. The storage mechanism 61 has multiple rod-shaped hooks (holding parts) 62A capable of holding the yarn tubes B. The storage mechanism 61 has a ring chain (ring-shaped belt member) 62B that is cyclically driven in a plane (vertical plane) substantially orthogonal to the length direction of the hooks 62A. The multiple hooks 62A are fixed to the ring chain 62B. Therefore, by continuously or intermittently cyclically driving the ring chain 62B in one direction, the yarn tubes B mounted on the hooks 62A can be conveyed along the length direction of the ring chain 62B. The ring chain 62B is driven by a drive unit 62C (see reference). Figure 6 (e.g., a motor) driven. The drive unit 62C is controlled by the machine control device 5C.

[0079] The storage mechanism 61 described above has multiple components. In this embodiment, two (dual-system) storage mechanisms (first storage mechanism 61A and second storage mechanism 61B) are provided, arranged in a left-right direction. The first storage mechanism 61A and the second storage mechanism 61B are stored in a housing 60A. The yarn tubes B stored in each of the first storage mechanism 61A and the second storage mechanism 61B can be first yarn tubes B1 and second yarn tubes B2 of different types, or they can be yarn tubes B of the same type.

[0080] The extraction mechanism 63 is a mechanism for extracting the yarn tube B from the hook 62A. The extraction mechanism 63 is located at an extraction position P0, which is part of the movement path of the hook 62A based on the cyclic drive of the chain 62B. The extraction mechanism 63 includes an extraction component 63A and a drive unit 63B (see reference 62A). Figure 6 The device includes detection sensors 63C and 63C. The removal component 63A removes the yarn tube B from the hanger 62A by pushing the yarn tube B forward. The drive unit 63B moves the removal component 63A in the front-back direction. An example of the drive unit 63B is a cylinder or the like, driven by air supplied from the air supply unit. The removal component 63A is a component capable of removing the yarn tube B from the removal position P0 set for each of the first storage mechanism 61A and the second storage mechanism 61B. Detection sensors 63C and 63C detect the presence or absence of the yarn tube B. Detection sensors 63C and 63C are configured to detect the yarn tube B located at a standby position P1 adjacent to the upstream side of the removal position P0 in the circulation direction of the chain 62B.

[0081] In the extraction mechanism 63 with this structure, if a yarn tube B is positioned at extraction position P0 of both the first storage mechanism 61A and the second storage mechanism 61B, then both yarn tubes B will be extracted. Therefore, the machine control device 5C controls the first storage mechanism 61A and the second storage mechanism 61B to deliver yarn tubes B from one of them to extraction position P0 at a time. Specifically, the machine control device 5C controls the first storage mechanism 61A and the second storage mechanism 61B to selectively deliver yarn tubes B to extraction position P0 if yarn tube B is detected by the detection sensors 63C, 63C.

[0082] The take-out mechanism 63 has a direction-changing mechanism 65 for changing the direction of the yarn tube B taken out from the hook 62A by the take-out member 63A. The direction-changing mechanism 65 receives the yarn tube B from the take-out position P0 with the large-diameter end of the yarn tube B facing upward and the small-diameter end facing downward. The direction-changing mechanism 65 changes the direction of the yarn tube B so that the large-diameter end of the yarn tube B faces downstream in the conveying direction in the conveying device 67, and delivers the yarn tube B to the conveying device 67.

[0083] The conveying device 67 is a device for transporting the yarn tube B between multiple storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) and the delivery mechanism 70. In this embodiment, one conveying device 67 is provided between the multiple storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) and the delivery mechanism 70. That is, only one transport path is formed between the multiple storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) and the delivery mechanism 70. The conveying device 67 is, for example, a belt conveyor comprising a pair of rollers 67A, 67A, a belt 67B suspended on the pair of rollers 67A, 67A, and a drive unit 67C (e.g., a motor) that drives one of the pair of rollers 67A, 67A. The drive unit 67C is controlled by a machine control device 5C.

[0084] The delivery mechanism 70 will take the conveyor 67 along the conveyor device 67 Figure 5 The white arrow indicates the mechanism that supplies yarn tube B to the doffing trolley 4. The delivery mechanism 70 is located downstream of the conveying device 67 in the conveying direction. (As shown) Figure 1 As shown by the double-dotted line, when the doffing trolley 4 reaches the supply position SP of the yarn tube storage section 60, the delivery mechanism 70 supplies yarn tube B to the doffing trolley 4. That is, in this embodiment, the supply position SP for supplying yarn tube B from the yarn tube storage section 60 is the position where the delivery mechanism 70 is arranged in the left-right direction of the arrangement of the spinning units 2.

[0085] like Figure 5 As shown, the delivery mechanism 70 is supported on a support portion 71 fixed to the first end frame 5A. The delivery mechanism 70 includes a conveyor belt 72, a drive portion 73, a distribution portion 75, a drive portion 76, a discharge portion 77, and a guide member 78.

[0086] A conveyor belt 72 is attached to a pair of rollers 73A and 73B. A drive unit 73 drives the conveyor belt 72 by rotating the rollers 73A. A feed mechanism 70 feeds the yarn tubes B forward by driving the conveyor belt 72 using the drive unit 73. The conveyor belt 72 is provided with multiple support portions 72A. The support portions 72A are arranged at predetermined intervals in the conveying direction of the conveyor belt 72. In the feed mechanism 70, one yarn tube B is received between two support portions 72A. In this embodiment, the feed mechanism 70 can hold four yarn tubes B.

[0087] The distribution unit 75 is a mechanism that distributes the yarn tubes B conveyed by the conveyor belt 72 to one of the multiple discharge units 77 (first discharge unit 77A and second discharge unit 77B). The opening of the first discharge unit 77A is provided above the first storage unit 41A, one of the multiple storage units (first storage unit 41A and second storage unit 41B) of the yarn magazine 41, which is located at the supply position SP. The opening of the second discharge unit 77B is provided above the second storage unit 41B. That is, yarn tubes B allocated to the first discharge unit 77A are supplied to the first storage unit 41A, and yarn tubes B allocated to the second discharge unit 77B are supplied to the second storage unit 41B.

[0088] The distribution unit 75 is located downstream of the conveyor belt 72 in the conveying direction; in other words, it is located in front of the conveyor belt 72. The distribution unit 75 is configured to swing in a forward-backward direction. When tilted forward S2, the distribution unit 75 guides the yarn tube B towards the first discharge section 77A; when tilted backward S1, it guides the yarn tube B towards the second discharge section 77B. The distribution unit 75 swings via a drive unit 76. The drive unit 76 is controlled by the machine control device 5C.

[0089] The guide component 78 prevents the yarn tube B, which is conveyed by the conveyor belt 72, from falling forward and guides the yarn tube B toward the second discharge section 77B.

[0090] Here, the control functions of the yarn tube storage unit 60, executed by the machine control device 5C, will be explained. For example... Figure 6 As shown, the machine control device 5C is configured to control the drive units 62C and 62C of the first storage mechanism 61A and the second storage mechanism 61B, the drive unit 63B of the retrieval mechanism 63, the drive unit 67C of the conveying device 67, and the drive units 73 and 76 of the delivery mechanism 70. Furthermore, the machine control device 5C is configured to acquire the detection results of the detection sensor 63C installed on the retrieval mechanism 63.

[0091] In this structure, the machine control device 5C is configured to switch between a single-yarn type mode and a multi-yarn type mode. The single-yarn type mode operates the yarn tube storage unit 60 when both storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) store yarn tubes of the same type. The multi-yarn type mode operates the yarn tube storage unit 60 when both first storage mechanism 61A and second storage mechanism 61B store yarn tubes of different types. Switching between the single-yarn type mode and the multi-yarn type mode is performed, for example, using the input key 5E. The settings for the single-yarn type mode and the multi-yarn type mode are displayed on the display screen 5D.

[0092] In single-yarn mode, the machine control device 5C controls the delivery mechanism 70 to supply one type of yarn tube B to the first storage section 41A and the second storage section 41B. Specifically, the machine control device 5C supplies the yarn tube B, which is conveyed by the conveyor belt 72, to the first storage section 41A and / or the second storage section 41B where there is a spare number of yarn tubes. The machine control device 5C can also control the delivery mechanism 70 to supply multiple (e.g., the maximum number of yarn tubes) of yarn tube B to the first storage section 41A and the second storage section 41B with a single command (single action). Furthermore, the machine control device 5C can also control the delivery mechanism 70 to supply one yarn tube B to either the first storage section 41A or the second storage section 41B with a single command (single action).

[0093] In the multi-variety mode, the machine control device 5C controls the delivery mechanism 70 to supply the first yarn tube B1 stored in the first storage mechanism 61A to the first storage section 41A and the second yarn tube B2 stored in the second storage mechanism 61B to the second storage section 41B. Specifically, when the yarn tube B transported by the conveyor belt 72 is the first yarn tube B1, the machine control device 5C controls the delivery mechanism 70 to guide the first yarn tube B1 to the first discharge section 77A by tilting the distribution section 75 forward S2. When the yarn tube B transported by the conveyor belt 72 is the second yarn tube B2, the machine control device 5C controls the delivery mechanism 70 to guide the second yarn tube B2 to the second discharge section 77B by tilting the distribution section 75 backward S1. The machine control device 5C controls the delivery mechanism 70, for example, to supply one yarn tube B to the first storage section 41A or the second storage section 41B with one command (one action).

[0094] The conveying device 80 is capable of conveying the package P discharged from the spinning unit 2 by the doffing trolley 4. For example... Figure 2 and Figure 3 As shown, a conveying device 80 is located between the spinning unit 2 and the doffing trolley 4. The conveying device 80 extends along the arrangement direction of the plurality of spinning units 2. The conveying direction of the package P realized by the conveying device 80 intersects (orthogonally) with the discharge direction of the package P from the spinning unit. The conveying device 80 drives a conveyor belt of a loop belt via a drive roller (not shown).

[0095] The effects of the spinning machine 1 described in the above embodiment will be explained. In the spinning machine 1 of this embodiment, the first storage section 41A and the second storage section 41B of the yarn magazine 41 of the doffing carriage 4 independently store the yarn tubes B. Therefore, different types of yarn tubes B can be stored in each of the first storage section 41A and the second storage section 41B. Thus, the doffing carriage 4 and the spinning machine 1 can handle multiple types. Furthermore, when only one type of yarn tube B is stored in the yarn magazine 41, the same yarn tube B can be stored in each of the first storage section 41A and the second storage section 41B, thus increasing the number of yarn tubes B stored in the doffing carriage 4 as a whole. Therefore, the doffing carriage 4 can handle even when the frequency of supplying yarn tubes B to the spinning unit 2 is high. In this way, the doffing carriage 4 can handle a wide variety of situations.

[0096] As described above, a single doffing carriage 4 can handle multiple yarn types and increase the number of yarn bobbins B that can be stored. Therefore, the spinning machine 1 does not need to have multiple doffing carriages 4, thus reducing costs. However, the spinning machine 1 can also have multiple (e.g., 2) doffing carriages 4.

[0097] In the spinning machine 1 of this embodiment, the yarn magazine 41 of the doffing carriage 4 has a first storage section 41A and a second storage section 41B. That is, the yarn magazine 41 has two or more but no more than four storage sections. In this structure, the large size of the doffing carriage 4 can be avoided.

[0098] In the spinning machine 1 of this embodiment, the doffing carriage 4 is equipped with a control unit 46. This control unit 46 determines whether to supply the first storage section 41A or the second storage section 41B of the yarn bobbin B to the bobbin mounting mechanism 42 after the doffing carriage 4 reaches the working position for the spinning unit 2. In this configuration, since the first storage section 41A or the second storage section 41B of the yarn bobbin B is supplied to the bobbin mounting mechanism 42 after the doffing carriage 4 reaches the working position, the appropriate yarn bobbin B can be reliably delivered to the spinning unit. For example, if the bobbin mounting mechanism 42 receives the yarn bobbin B from the first storage section 41A or the second storage section 41B at an earlier stage, and the type of yarn bobbin B actually required changes after its receipt, the bobbin mounting mechanism 42 may need to temporarily discharge the received yarn bobbin B. Alternatively, the doffing carriage 4 may remain idle until it can supply the already received yarn bobbin B to a spinning unit 2. In the doffing carriage 4 of the spinning machine 1 in this embodiment, such an action can be avoided, thus enabling the efficient delivery of the appropriate yarn tube B to the spinning unit 2.

[0099] In the spinning machine 1 of this embodiment, the first storage section 41A and the second storage section 41B respectively store the yarn tubes B in a vertically stacked manner, with the axis of the yarn tubes B along the traveling direction when viewed from the traveling direction of the doffing carriage 4. The first storage section 41A and the second storage section 41B can also be arranged in a front-back direction. In this structure, the doffing carriage 4 can be compactly configured.

[0100] In the spinning machine 1 of this embodiment, the doffing trolley 4 includes a housing 40 that houses a yarn magazine 41 and a yarn tube mounting mechanism 42, and spare yarn magazines 45A and 45B disposed on the outer side of the housing 40 and holding the yarn tubes B. In this structure, the operator can move the yarn tubes B held in the spare yarn magazines 45A and 45B to the first storage section 41A and / or the second storage section 41B at any time.

[0101] In the spinning machine 1 of this embodiment, as Figure 1 As shown, the conveying device 67 for transporting the yarn tube B is positioned within a second region A2 adjacent to the first region A1 where multiple spinning units 2 are arranged. Therefore, compared to conventional conveying devices where the transport path extends along the multiple spinning units 2 arranged in the arrangement direction, the transport path can be shortened. Furthermore, since the transport path of the conveying device 67 in the spinning machine 1 of the above embodiment extends from the storage mechanism 61, it is located relatively close to the storage mechanism 61. Therefore, the operator can monitor the transport status of the conveying device 67 while performing supplementary work at the storage mechanism 61. That is, the operator's workload during the operation of the spinning machine 1 can be reduced.

[0102] In the spinning machine 1 of this embodiment, the conveying device 67 is shared by multiple storage mechanisms 61, thus avoiding the need for a large yarn tube storage unit 60, and the yarn tube storage unit 60 can supply yarn tubes B from multiple storage mechanisms 61 to a doffing trolley 4 with a simple structure.

[0103] In the spinning machine 1 of this embodiment, the take-out mechanism 63 for taking out the yarn tube B from the hanger 62A is shared by multiple storage mechanisms 61, thus avoiding the large size of the yarn tube storage unit 60, and the yarn tube storage unit 60 can take out the yarn tube B from multiple storage mechanisms 61 with a simple structure.

[0104] In the spinning machine 1 of this embodiment, the machine control device 5C is configured to switch between a single-yarn-type mode that operates when multiple storage mechanisms 61 each store the same type of yarn bobbin B, and a multi-yarn-type mode that operates when multiple storage mechanisms 61 each store first yarn bobbins B1 and second yarn bobbins B2 of different types. Therefore, when the same type of yarn bobbin B is stored in the first storage mechanism 61A and the second storage mechanism 61B, and when different types of yarn bobbins B are stored in the first storage mechanism 61A and the second storage mechanism 61B, the yarn bobbin storage unit 60 can perform different optimal operations.

[0105] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and various modifications can be made without departing from its spirit. The above embodiments and / or the following variations can be appropriately combined.

[0106] In the above-described embodiment of the doffing trolley 4, an example with two storage sections, namely the first storage section 41A and the second storage section 41B, has been described. However, the yarn storage 41 may also have three storage sections or four storage sections.

[0107] In the yarn tube storage unit 60 of the above embodiment, an example with two storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) has been described. However, the yarn tube storage unit 60 may also have three storage mechanisms 61, four storage mechanisms 61, or even five or more storage mechanisms 61. Moreover, these multiple storage mechanisms 61 may be arranged inside a single housing 60A, or each storage mechanism 61 may be arranged in a different housing 60A.

[0108] In the yarn tube storage unit 60 described in the above embodiments and variations, an example has been given in which a conveying device 67 is arranged between multiple storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) and the delivery mechanism 70. However, multiple conveying devices 67 may also be arranged. Similarly, multiple delivery mechanisms 70 may also be arranged. Moreover, the number of conveying devices 67 may be the same as the number of storage mechanisms 61 located upstream of the yarn tube B in the supply direction in the yarn tube storage unit 60. For example, if two storage mechanisms 61 (first storage mechanism 61A and second storage mechanism 61B) are arranged as in this embodiment, two conveying devices 67 may be arranged accordingly. Similarly, the number of delivery mechanisms 70 may be the same as the number of storage mechanisms 61 or conveying devices 67. In other words, the yarn tube storage unit 60 may be configured to provide a dedicated yarn tube transport path to the yarn magazine 41 for each storage mechanism 61.

[0109] In the yarn tube storage unit 60 of the above embodiment, an example has been described in which yarn tubes B are selectively supplied to the first storage unit 41A and the second storage unit 41B provided in the yarn magazine 41 by distributing yarn tubes B to the first discharge unit 77A and the second discharge unit 77B. Alternatively, instead of such a feeding mechanism 70, the discharge units can be integrated into one unit, and the discharge unit can be configured as follows: Figure 5 The structure shown allows movement along direction D. In this case, if the yarn tube B conveyed by the conveyor belt 72 is the first yarn tube B1, the discharge section is moved above the first storage section 41A, causing the first yarn tube B1 to fall into the first storage section 41A. If the yarn tube B is the second yarn tube B2, the discharge section is moved above the second storage section 41B, causing the second yarn tube B2 to fall into the second storage section 41B.

[0110] In the above embodiments and variations, the form in which yarn tubes B are supplied from the yarn tube storage unit 60 to the first storage unit 41A and the second storage unit 41B of the doffing trolley 4 is described as an example. However, the operator may also supply the yarn tubes B to one of the storage units of the first storage unit 41A and the second storage unit 41B. That is, the first storage unit 41A and / or the second storage unit 41B are configured to accept yarn tubes B from sources other than the delivery unit 70. Thus, for example, the operator may supply the yarn tubes B to one of the storage units of the first storage unit 41A and the second storage unit 41B, and the yarn tube storage unit 60 may supply the yarn tubes B to the other storage unit of the first storage unit 41A and the second storage unit 41B.

[0111] For example, if two types of yarn Y are produced in the spinning machine 1, and the number of spinning units 2 producing one type of yarn Y is small, then the supply of yarn bobbins B to the spinning units 2 producing the other type of yarn Y becomes the majority. That is, the yarn bobbins B are basically supplied from the yarn bobbin storage section 60. In this case, it is efficient to supply only the yarn bobbins B from the yarn bobbin storage section 6 to the doffing trolley 4. Therefore, it is preferable for the operator to supply the yarn bobbins B to the spinning units 2 producing one type of yarn Y. In this case, the manually supplied yarn bobbins B can also be stored in advance in the spare yarn magazines 45A and 45B. Moreover, in this case, if the spinning units 2 using manually supplied yarn bobbins B are located far from the yarn bobbin storage section 60, the travel distance of the doffing trolley 4 can be shortened, thus improving the overall efficiency of the spinning machine 1.

[0112] In a configuration where the operator supplies yarn tube B to either the first storage section 41A or the second storage section 41B, it can also be configured such that the delivery mechanism 70 supplies yarn tube B to the first storage section 41A, and the operator supplies yarn tube B to the second storage section 41B. For example... Figure 3As shown, the second storage unit 41B is located at the front of the yarn magazine 41. A working passage for the operator is provided at the front of the doffing trolley 4. Therefore, compared to the first storage unit 41A located at the rear of the yarn magazine 41, the second storage unit 41B located at the front of the yarn magazine 41 is easier for the operator to supply the yarn tubes B. Thus, by having the operator supply the yarn tubes B to the second storage unit 41B, operability can be improved.

[0113] In the above embodiments and variations, the yarn winding machine is described as a spinning machine 1 and the winding unit is a spinning unit 2 as an example. However, the yarn winding machine can also be an automatic winding machine or a free-end spinning machine.

[0114] In the above embodiments and modifications, the configuration in which a doffing trolley 4 is provided between the spinning unit 2 and the conveying device 80 is described as an example. However, the conveying device 80 may also be provided between the spinning unit 2 and the doffing trolley 4.

[0115] In the above embodiments and variations, the configuration of the yarn tube storage section 60 at one end (the end where the first end frame 5A is disposed) in the arrangement direction of the plurality of spinning units 2 has been described as an example. However, the yarn tube storage section 60 may also be disposed at the other end (the end where the second end frame 5B is disposed) in the arrangement direction of the plurality of spinning units 2. Multiple yarn tube storage sections 60 may also be provided. In this case, the spinning machine 1 may also have multiple doffing trolleys 4.

[0116] In the above embodiments and variations, Figure 1 The figure shows the yarn tube B stored in the yarn tube storage section 60 in a state that can be visually observed by the operator from the front of the spinning machine 1. However, the configuration of the yarn tube storage section 60 is not limited to this configuration; for example, it may be configured on the side and / or back of the spinning machine 1. Instead of configuring the yarn tube storage section 60 at the end of the spinning machine 1 in the longitudinal direction (the arrangement direction of the spinning units 2), the yarn tube storage section 60 may be configured at the center of the spinning machine 1 in the longitudinal direction.

[0117] The moment when the doffing trolley 4 moves to the supply position SP of the yarn tube storage section 60 and collects a new yarn tube B can be, for example, after the number of yarn tubes B stored in the yarn magazine 41 becomes 0, after the number of yarn tubes B stored in one of the first storage sections 41A and the second storage section 41B becomes 0, or when there is no request for yarn tube B from any spinning unit 2 when the yarn magazine 41 is not full.

[0118] In the above embodiments and variations, the conveying device 80 was described as a conveyor belt as an example. However, the method of conveying the package P based on the conveying device 80 is not limited to a conveyor belt, and the conveying device 80 can also be other mechanisms. In addition, the conveying device 80 may not have a conveying function, as long as it can hold the package P discharged from the spinning unit 2.

[0119] In the above embodiment, the yarn tube storage section 60 with the direction conversion mechanism 65 was described as an example. However, the direction conversion mechanism 65 may not be provided in the yarn tube storage section 60.

[0120] In the above embodiments and variations, an example is given where four first yarn tubes B1 are stored in the first storage section 41A and four second yarn tubes B2 are stored in the second storage section 41B of the yarn storage 41 of the doffing trolley 4. However, the number of yarn tubes stored can be set appropriately.

[0121] In the above embodiments and modifications, in the spinning machine 1, each device is arranged such that the yarn Y supplied from the upper side in the height direction is wound on the lower side. However, in the spinning machine, each device may also be arranged such that the yarn supplied from the lower side is wound on the upper side. In addition, in the above embodiments and modifications, there are devices in which the drive unit is shared in multiple spinning units 2, but the spinning machine 1 may also be configured such that in each spinning unit 2, all devices are driven independently relative to the other spinning units 2.

[0122] In the above embodiments and modifications, a configuration in which a display screen 5D and an input key 5E are provided on the second end frame 5B has been described as an example. However, a touch panel display may also be provided on the second end frame 5B instead of a display screen and input keys.

[0123] In the above embodiments and modifications, the doffing carriage 4 traveling on the travel path R2 was described as an example. However, the doffing carriage 4 may also travel on a track. The yarn receiving carriage 3 may also travel on a track. The yarn receiving carriage 3 may also be omitted, and the spinning machine 1 may be configured such that each spinning unit 2 has at least a part of the structure associated with the yarn receiving operation.

[0124] exist Figure 1 In the diagram, the spinning machine 1 is shown winding a conical package P, but it can also wind a cylindrical package P. In this case, the bobbin storage section 60 supplies the first cylindrical bobbin B1 and the second cylindrical bobbin B2 to the doffing carriage 4.

[0125] In spinning unit 2, the yarn storage device 11 has the function of drawing yarn Y from the air spinning device 7, but yarn Y can also be drawn from the air spinning device 7 using the guide roller and the clamping roller. When drawing yarn Y from the air spinning device 7 using the guide roller and the clamping roller, the yarn storage device 11 can be replaced by a loose tube and / or a mechanical compensator that absorbs slack in yarn Y by attracting airflow.

[0126] The tension sensor 9 can also be positioned upstream of the yarn monitoring device 8 in the direction of yarn Y's travel. The unit controller 10 can also be provided for each spinning unit 2. In the spinning unit 2, the waxing device 12, the tension sensor 9, and the yarn monitoring device 8 can also be omitted. If the yarn Y is not waxed, the waxing device 12 can be provided in the spinning unit 2, and the wax can be removed from the waxing device 12.

[0127] The materials and shapes of each structure are not limited to those mentioned above; a wide variety of materials and shapes can be used.

[0128] In the above embodiment, the yarn tube storage unit 60 is described as having a delivery mechanism 70, and the distribution unit 75 of the delivery mechanism 70 distributes the yarn tubes B conveyed by the conveyor belt 72 to the first discharge unit 77A and the second discharge unit 77B as an example. Yarn tubes B distributed to the first discharge unit 77A are supplied to the first storage unit 41A, and yarn tubes B distributed to the second discharge unit 77B are supplied to the second storage unit 41B. That is, in the above embodiment, the yarn tubes B are distributed to the first storage unit 41A or the second storage unit 41B of the yarn magazine 41 in the doffing trolley 4 by the delivery mechanism 70 of the yarn tube storage unit 60. However, the distribution of yarn tubes B to the first storage unit or the second storage unit can also be performed by the doffing trolley. In this case, the yarn tube storage unit 60 may not have a distribution unit 75. Furthermore, the yarn tube storage unit 60 may only have a storage mechanism 61.

[0129] like Figures 7-9 As shown, the doffing trolley 4A has a yarn magazine 90. The yarn magazine 90 includes a yarn magazine body 91, a distribution mechanism 92, a flap mechanism 93, a first supply mechanism 94, a second supply mechanism 95, a first sensor 96A, a second sensor 96B, a third sensor 96C, and a fourth sensor 96D (see reference). Figure 11 ).

[0130] The yarn storage body 91 has a first storage section 91A for storing a first yarn tube B1 and a second storage section 91B for storing a second yarn tube B2. The first storage section 91A and the second storage section 91B independently store the first yarn tube B1 and / or the second yarn tube B2, respectively. The first storage section 91A and the second storage section 91B are arranged side by side. Specifically, the first storage section 91A and the second storage section 91B are arranged side by side in the front-rear direction of the doffing carriage 4A. The first storage section 91A is located at the rear side in the front-rear direction of the doffing carriage 4A. The second storage section 91B is located at the front side in the front-rear direction of the doffing carriage 4A.

[0131] The first storage section 91A stores the first yarn tube B1 such that, when viewed from the traveling direction of the doffing trolley 4, the axis of the first yarn tube B1 is along the traveling direction. The first storage section 91A stores multiple first yarn tubes B1 stacked vertically. The first storage section 91A has an inlet section 91Aa and an outlet section 91Ab. The inlet section 91Aa is located at the upper part of the first storage section 91A. The inlet section 91Aa is the portion through which the first yarn tube B1 passes when it is introduced into the first storage section 91A. The first yarn tube B1 is introduced into the first storage section 91A via the inlet section 91Aa. The outlet section 91Ab is located at the lower part of the first storage section 91A. The outlet section 91Ab is the portion through which the first yarn tube B1 passes when it is delivered from the first storage section 91A to the yarn tube mounting mechanism 42. The second yarn tube B2 is delivered from the first storage section 91A to the yarn tube mounting mechanism 42 via the outlet section 91Ab.

[0132] The second storage section 91B stores the second yarn tube B2 in such a way that the axis of the second yarn tube B2 is along the direction of travel when viewed from the traveling direction of the doffing trolley 4A. The second storage section 91B stores multiple second yarn tubes B2 stacked vertically. The second storage section 91B has an inlet section 91Ba and an outlet section 91Bb. The inlet section 91Ba is located at the upper part of the second storage section 91B. The inlet section 91Ba is the portion through which the second yarn tube B2 passes when it is introduced into the second storage section 91B. The second yarn tube B2 is introduced into the second storage section 91B via the inlet section 91Ba. The outlet section 91Bb is located at the lower part of the second storage section 91B. The outlet section 91Bb is the portion through which the second yarn tube B2 passes when it is delivered from the second storage section 91B to the yarn tube mounting mechanism 42. The second yarn tube B2 is delivered from the second storage section 91B to the yarn tube mounting mechanism 42 via the outlet section 91Bb.

[0133] The dispensing mechanism 92 dispenses the yarn tubes B supplied from the yarn tube storage section 60 to either the first storage section 91A or the second storage section 91B. For example... Figure 10 As shown, the dispensing mechanism 92 has a rotating shaft 92A, a dispensing section 92B, and a driving section 92C (see reference). Figure 11 (e.g., cylinder).

[0134] A rotating shaft 92A is positioned between the first storage section 91A and the second storage section 91B in the longitudinal direction of the doffing carriage 4. More specifically, the rotating shaft 92A is positioned between the first storage section 91A and the second storage section 91B, and is positioned above the first storage section 91A and the second storage section 91B in the vertical direction of the doffing carriage 4. The rotating shaft 92A is rotatably supported on the yarn magazine body 91. The rotating shaft 92A has a cylindrical shape. The rotating shaft 92A is arranged to extend along the travel direction of the doffing carriage 4A. The axial direction of the rotating shaft 92A is consistent with the travel direction of the doffing carriage 4A.

[0135] The distribution unit 92B is connected to the rotating shaft 92A and oscillates around the rotating shaft 92A. The distribution unit 92B can be in the first position P11 (see reference). Figure 7 and Figure 9 ) and the second position P22 (refer to) Figure 8 It swings between ) . For example Figure 7 As shown, the first position P11 is the position where the distribution unit 92B distributes the yarn tube B to the first storage unit 91A. Figure 9 As shown, the first position P11 is also the position where the distribution unit 92B guides the yarn tube B to the second storage unit 91B. Figure 8 As shown, the second position P22 is the position where the yarn tube B is received when the distribution unit 92B distributes the yarn tube B to the second storage unit 91B. The second position P22 can also be described as the position where the yarn tube B is restricted (prevented) from moving towards the first storage unit 91A before the distribution unit 92B distributes the yarn tube B to the second storage unit 91B, so that the yarn tube B is stored in the first storage unit 91A.

[0136] like Figure 10 As shown, the distribution section 92B has a pair of guide sections 92D and a limiting section 92E. The pair of guide sections 92D support the limiting section 92E. The pair of guide sections 92D are connected to the rotation shaft 92A. Specifically, the pair of guide sections 92D are arranged opposite each other in a manner that is spaced apart by a predetermined interval in the axial direction of the rotation shaft 92A.

[0137] The guide portion 92D has a guide portion 92Da and a limiting portion 92Db. The guide portion 92Da and the limiting portion 92Db are integrally formed. The guide portion 92D has a generally V-shaped form when viewed along the axial direction of the rotation axis 92A. The guide portion 92Da extends in a direction orthogonal to the axial direction of the rotation axis 92A (extending radially along the rotation axis 92A) when viewed along the axial direction of the rotation axis 92A. The limiting portion 92Db extends in a direction orthogonal to the axial direction of the rotation axis 92A (extending radially along the rotation axis 92A) when viewed along the axial direction of the rotation axis 92A.

[0138] The guide portion 92Da is longer than the restricting portion 92Db. The length of the guide portion 92Da is set such that the yarn tube B can be retrieved from the main body 93A (described later) of the baffle mechanism 93 when the guide portion 92D is in the second position P22. The guide portion 92Da and the restricting portion 92Db form a predetermined angle (e.g., an angle greater than 90° and less than 180°) when viewed along the axial direction of the rotation axis 92A. The base end portions of the guide portion 92Da and the restricting portion 92Db are connected to the rotation axis 92A.

[0139] The limiting part 92E has a pair of connecting plates 92Ea and 92Eb connected to the guide part 92D, and a limiting plate 92Ec connecting the pair of connecting plates 92Ea and 92Eb. Connecting plate 92Ea is connected to one guide part 92Da, and connecting plate 92Eb is connected to the other guide part 92Da. The limiting plate 92Ec extends axially along the rotation axis 92A. The limiting plate 92Ec has a rectangular shape.

[0140] The drive unit 92C drives the distribution unit 92B. The drive unit 92C is located in the yarn storage body 91. The drive unit 92C causes the distribution unit 92B to swing between a first position P11 and a second position P22. The operation of the drive unit 92C (distribution mechanism 92) is controlled by the control unit 46.

[0141] A baffle mechanism 93 blocks the yarn tube B. The baffle mechanism 93 is located above the first storage section 91A. The baffle mechanism 93 includes a main body section 93A and a drive section 93B (see reference). Figure 11 (e.g., a cylinder). The main body 93A is disposed in the first storage section 91A at the rear side of the doffing trolley 4A in the front-rear direction. The main body 93A is configured to swing about an axis centered on the traveling direction of the doffing trolley 4A. The main body 93A is in a first position where it does not enter the first storage section 91A and a second position where it enters the first storage section 91A ( Figures 7-9 It swings between the positions shown. The operation of the baffle mechanism 93 is controlled by the control unit 46.

[0142] The first supply mechanism 94 supplies the first yarn tube B1 from the first storage section 91A to the yarn tube mounting mechanism 42. The first supply mechanism 94 is located at the lower end of the first storage section 91A. The first supply mechanism 94 includes a gate 94A and a drive section 94B (see reference). Figure 11 (e.g., a cylinder) is constructed. The first supply mechanism 94 supplies the first yarn tubes B1 one by one to the yarn tube mounting mechanism 42 from the outlet 91Ab. The operation of the first supply mechanism 94 is controlled by the control unit 46.

[0143] The second supply mechanism 95 supplies the second yarn tube B2 from the second storage section 91B to the yarn tube mounting mechanism 42. The second supply mechanism 95 is located at the lower end of the second storage section 91B. The second supply mechanism 95 includes a gate 95A and a drive section 95B (see reference). Figure 11 (e.g., a cylinder) is constructed. The second supply mechanism 95 supplies the second yarn tubes B2 one by one to the yarn tube mounting mechanism 42 from the outlet 91Bb. The operation of the second supply mechanism 95 is controlled by the control unit 46.

[0144] The first sensor 96A, the second sensor 96B, the third sensor 96C, and the fourth sensor 96D respectively detect the presence or absence of yarn tube B. The first sensor 96A detects the presence or absence of yarn tube B at the inlet 91Aa side (upper side) of the first storage section 91A. The second sensor 96B detects the presence or absence of yarn tube B at the outlet 91Ab side (lower side) of the first storage section 91A. The third sensor 96C detects the presence or absence of yarn tube B at the inlet 91Ba side (upper side) of the second storage section 91B. The fourth sensor 96D detects the presence or absence of yarn tube B at the outlet 91Bb side (lower side) of the second storage section 91B. Figure 11 As shown, the first sensor 96A, the second sensor 96B, the third sensor 96C, and the fourth sensor 96D output the detection results to the control unit 46.

[0145] Next, the operation of storing the yarn tube B in the first storage section 91A or the second storage section 91 in the yarn storage 90 will be explained. First, the case where the yarn tube B (first yarn tube B1) is stored in the first storage section 91A will be explained. Figure 7 As shown, when the yarn tube B is distributed to the first storage section 91A, the distribution section 92B of the distribution mechanism 92 is positioned at the first position P11, and the main body 93A of the baffle mechanism 93 is positioned at the second position. After the yarn tube B supplied from the yarn tube storage section 60 is received by the main body 93A, its movement towards the second storage section 91B is restricted (prevented) by the restriction section 92E of the distribution section 92B. Then, the main body 93A is moved from the second position to the first position by the drive section 93B, thereby storing the yarn tube B in the first storage section 91A.

[0146] Next, the operation of storing yarn tube B (second yarn tube B2) in the second storage section 91B will be explained. For example... Figure 8 As shown, when distributing yarn tube B to the second storage section 91B, the main body 93A of the baffle mechanism 93 is positioned in the second position, and the distribution section 92B of the distribution mechanism 92 is positioned in the second position P22. Yarn tube B supplied from the yarn tube storage section 60, after being received by the main body 93A, moves towards the distribution section 92B. Yarn tube B moves on the guide portion 92Da of the guide portion 92D, and its movement is restricted (stopped) by the restricting portion 92Db. Next, as... Figure 9As shown, if a predetermined time elapses from when the distribution section 92B is in the second position P22, the drive section 92C moves the distribution section 92B from the second position P22 to the first position P11. As a result, the yarn tube B is guided into the second storage section 91B.

[0147] Next, the operation of the doffing carriage 4A when it receives yarn tubes B from the yarn tube storage section 60 will be explained. Hereinafter, the supply of a yarn tube B to the first storage section 41A and the second storage section 41B will be described. In the doffing carriage 4A, yarn tubes B are first supplied to the second storage section 91B. That is, in the doffing carriage 4A, yarn tubes B are first supplied to the second storage section 91B, and after the number of yarn tubes B in the second storage section 91B is full, yarn tubes B are then supplied to the first storage section 91A.

[0148] The doffing trolley 4A moves to the supply position SP of the yarn tube storage section 60 and stops at the supply position SP. At this time, in the yarn magazine 90 of the doffing trolley 4A, the distribution section 92B of the distribution mechanism 92 is located in the first position P11, and the main body 93A of the baffle mechanism 93 is located in the second position.

[0149] like Figure 12 As shown, if the doffing trolley 4A reaches the supply position SP, it determines whether the number of yarn tubes B in the second storage section 91B is full, i.e., whether the third sensor 96C is ON (step S01). If the doffing trolley 4A does not determine that the number of yarn tubes B in the second storage section 91B is full, i.e., the third sensor 96C is OFF (step S01: No), it proceeds to... Figure 13 The "A" shown.

[0150] When the doffing trolley 4A determines that the number of yarn tubes B in the second storage section 91B is full, i.e., when the third sensor 96C is ON (step S01: Yes), it determines whether the number of yarn tubes B in the first storage section 91A is full, i.e., whether the first sensor 96A is ON (step S02). When the doffing trolley 4A determines that the number of yarn tubes B in the first storage section 91A is full, i.e., when the first sensor 96A is ON (step S02: Yes), it does not accept the supply of yarn tubes B from the yarn tube storage section 60.

[0151] When the doffing carriage 4A determines that the number of yarn tubes B in the first storage section 91A is not full, i.e., the first sensor 96A is OFF (step S02: No), it determines whether a yarn tube B is stored in the first storage section 91A, i.e., whether the second sensor 96B is ON (step S03). When the doffing carriage 4A determines that a yarn tube B is stored in the first storage section 91A, i.e., the second sensor 96B is ON (step S03: Yes), it accepts the supply of one yarn tube B and stores the yarn tube B in the first storage section 91A (step S04). At this time, with the distribution mechanism 92 in the first position P11, the doffing carriage 4A moves the main body 93A of the baffle mechanism 93 to the second position to accept the supply of yarn tube B. Then, by moving the main body 93A to the first position, the yarn tube B is stored in the first storage section 91A. If the doffing trolley 4 saves the yarn tube B to the first storage unit 91A, it returns to the processing of step S02.

[0152] If the doffing trolley 4A determines that the yarn tube B is not stored in the first storage unit 91A, i.e., the second sensor 96B is OFF (step S03: No), it continuously accepts the supply of a predetermined number of yarn tubes B and stores the yarn tubes B in the first storage unit 91A (step S05). If the doffing trolley 4 stores the yarn tube B in the first storage unit 91A, it returns to the processing in step S02.

[0153] like Figure 13 As shown, if the doffing trolley 4A does not determine that the number of yarn tubes B in the second storage section 91B is full, i.e., the third sensor 96C is OFF (step S01: No), it determines whether the number of yarn tubes B in the first storage section 91A is full, i.e., whether the first sensor 96A is ON (step S06). If the doffing trolley 4A determines that the number of yarn tubes B in the first storage section 91A is full, i.e., the first sensor 96A is ON (step S06: Yes), it cannot position the distribution section 92B in the second position P22, so it does not receive the supply of yarn tubes B from the yarn tube storage section 60.

[0154] If the doffing carriage 4A does not determine that the number of yarn tubes B in the first storage section 91A is full, i.e., the first sensor 96A is OFF (step S06: No), it accepts the supply of yarn tubes B and stores them in the second storage section 91B (step S07). In step S07, after the main body 93A is in the second position and the distribution section 92B of the distribution mechanism 92 is in the second position P22, the doffing carriage 4A accepts the supply of yarn tubes B. After a predetermined time has elapsed since the supply of yarn tubes B was accepted, the doffing carriage 4A moves the main body 93A from the second position to the first position and moves the distribution section 92B from the second position P22 to the first position P11. Thus, the yarn tubes B are stored in the second storage section 91B.

[0155] The doffing trolley 4A is equipped with an installation detection sensor (not shown) that detects whether yarn tube B is present in the yarn tube installation mechanism 42. After storing yarn tube B in the second storage unit 91B, the doffing trolley 4A determines whether yarn tube B is present in the yarn tube installation mechanism 42 based on the detection result of the installation detection sensor (step S08). When the doffing trolley 4A determines that yarn tube B is present in the yarn tube installation mechanism 42, that is, when the installation detection sensor is ON (step S08: Yes), the doffing trolley 4A proceeds to... Figure 12 The "B" shown.

[0156] If the doffing carriage 4A determines that there is no yarn tube B in the yarn tube mounting mechanism 42, i.e., the installation detection sensor is OFF (step S08: No), it determines whether yarn tube B is stored in the second storage section 91B, i.e., whether the fourth sensor 96D is ON (step S09). If the doffing carriage 4A determines that there is no yarn tube B stored in the second storage section 91B, i.e., the fourth sensor 96D is OFF (step S09: No), it issues an alarm (step S10). For example, as a reason for this situation, it is conceivable that the yarn tube B is blocked on the path from the hook 62 of the yarn tube storage section 60 to the doffing carriage 4A. The spinning machine 1 may, for example, issue an alarm to an output section (at least one of a display, light, and speaker, etc.) of the doffing carriage 4A and / or the yarn tube storage section 60, etc. (not shown). The spinning machine 1 may also issue an alarm by displaying a message on the display screen 5D.

[0157] When the doffing carriage 4A determines that yarn tube B is stored in the second storage section 91B, i.e., when the fourth sensor 96D is ON (step S09: Yes), it supplies yarn tube B from the second storage section 91B to the yarn tube mounting mechanism 42 (step S11). After supplying yarn tube B from the second storage section 91B to the yarn tube mounting mechanism 42, the doffing carriage 4A determines whether there is yarn tube B in the yarn tube mounting mechanism 42 (step S12). When the doffing carriage 4A determines that there is yarn tube B in the yarn tube mounting mechanism 42, i.e., when the mounting detection sensor is ON (step S12: Yes), it proceeds to... Figure 12 The doffing trolley 4A, when it determines that there is no yarn tube B in the yarn tube installation mechanism 42, that is, when the installation detection sensor is OFF (step S12: No), issues an alarm (step S10).

[0158] Alternatively, if the doffing trolley 4A determines in step S06 that the number of yarn tubes B in the first storage unit 91A is full, it supplies yarn tubes B from the first storage unit 91A to the yarn tube mounting mechanism 42, proceeding to step S07. By supplying yarn tubes B from the first storage unit 91A to the yarn tube mounting mechanism 42, the distribution unit 92B can be positioned at the second position P22. Alternatively, after supplying yarn tubes B from the first storage unit 91A to the yarn tube mounting mechanism 42, if the doffing trolley 4A determines that there are yarn tubes B in the yarn tube mounting mechanism 42, i.e., the installation detection sensor is ON, it proceeds to step S07. Alternatively, after supplying yarn tubes B from the first storage unit 91A to the yarn tube mounting mechanism 42, if the doffing trolley 4A determines that there are no yarn tubes B in the yarn tube mounting mechanism 42, i.e., the installation detection sensor is OFF, it outputs an alarm. In this case, imagine that during the supply of yarn tube B from the first storage section 91A to the yarn tube installation mechanism 42, yarn tube B gets stuck somewhere.

[0159] As described above, the doffing trolley 4A is equipped with a distribution mechanism 92, which distributes the yarn tubes B supplied to the yarn magazine 90 to one of the inlet portions 91Aa of the first storage section 91A and 91Ba of the second storage section 91B. In this configuration, the distribution mechanism 92 provided by the doffing trolley 4A itself can distribute the yarn tubes B supplied to the yarn magazine 90 to either the first storage section 91A or the second storage section 91B.

[0160] In the doffing trolley 4A, since the yarn magazine 90 is equipped with a distribution mechanism 92, the yarn tubes B can be distributed to the first storage section 91A or the second storage section 91B in a compact structure. This avoids the need for a large doffing trolley 4A, reduces costs due to a reduction in the number of parts, and facilitates maintenance. Furthermore, since the yarn tubes B are distributed within the doffing trolley 4A, the speed of yarn tube B distribution processing can be increased. Therefore, the processing capacity of the doffing trolley 4A can be improved.

[0161] In the doffing trolley 4A, the dispensing mechanism 92 includes: a rotating shaft 92A disposed between the first storage section 91A and the second storage section 91B and extending along the arrangement direction; and a dispensing section 92B connected to the rotating shaft 92A and oscillating about the rotating shaft 92A. In this structure, by oscillating the dispensing section 92B, the yarn tube B can be dispensed to either the first storage section 91A or the second storage section 91B. Since the dispensing mechanism 92 has a simple structure with a rotating shaft 92A and a dispensing section 92B, the large size of the doffing trolley 4A can be avoided.

[0162] In the doffing trolley 4A, the dispensing mechanism 92 has a drive unit 92C that moves the dispensing section 92B between a first position P11 and a second position P22. The dispensing section 92B has a guide section 92D that guides the yarn tube B and a limiting section 92E that restricts the movement of the yarn tube B. In the doffing trolley 4A, when the yarn tube B is stored in the first storage section 91A, the drive unit 92C moves the dispensing section 92B to the first position P11, and the limiting section 92E restricts the movement of the yarn tube B towards the second storage section 91B, thereby dispensing the yarn tube B into the first storage section 91A. In the doffing trolley 4A, when storing the yarn tube B in the second storage section 91B, after using the drive unit 92C to position the distribution unit 92B at the second position P22 and using the guide unit 92D to guide the yarn tube B to the second storage section 91B, the drive unit 92C is used to position the distribution unit 92B at the first position P11, thereby distributing the yarn tube B to the second storage section 91B. In this structure, by using the drive unit 92C to move the distribution unit 92B to the first position P11 and the second position P22, the yarn tube B can be accurately distributed to the first storage section 91A or the second storage section 91B.

[0163] Based on the above implementation methods, such as Figure 14 As shown, the yarn storage compartment 90 of the doffing trolley 4A may also include a baffle mechanism 97. The baffle mechanism 97 is connected to the supplied second yarn tube B2. The baffle mechanism 97 is located above the second storage section 91B. The baffle mechanism 97 comprises a main body 97A and a drive unit (not shown). The main body 97A is configured to swing about an axis centered on the travel direction of the doffing trolley 4A. The main body 97A is in a first position where it does not enter the second storage section 91B (…). Figure 14The position shown oscillates between the second position (where it enters the second storage section 91B) and the second position. The operation of the baffle mechanism 97 is controlled by the control unit 46.

[0164] In the doffing trolley 4A equipped with the baffle mechanism 97, for example, when the operator supplies the yarn tube B to the second storage section 91B, the main body 97A is positioned in the second position. Thus, after the baffle mechanism 97 temporarily catches the yarn tube B supplied to the second storage section 91B and stabilizes the position of the yarn tube B, the baffle mechanism 97 is moved to the first position, thereby guiding the yarn tube B into the second storage section 91B.

[0165] In the doffing trolley 4A described above, the configuration in which the guide portion 92D of the distribution section 92B of the distribution mechanism 92 has a limiting portion 92Db is described as an example. However, the guide portion 92D may also not have the limiting portion 92Db. In this configuration, the yarn tube B, after moving on the guide portion 92Da, is restricted (stopped) from moving by the rotating shaft 92A.

[0166] In the above embodiment, the doffing trolley 4A is equipped with a cylinder as the drive mechanism for each component. However, the drive mechanism can also be a hydraulic cylinder or a motor, or other drive structures.
