The yarn monitoring device 35 may be provided between the yarn supplying unit 31 and the yarn accumulating device 32.

<Winding part>
Next, the configuration of the winding unit 33 will be described in detail. As shown in FIGS. 2 to 7, the winding unit 33 includes a cradle 81 (“bobbin mounting portion” of the present invention), a winding drum 82, two swing arms 83 and 84, a stopper 85, A rocker 86, a contact pressure adjusting unit 87, a first sensor 88, and a second sensor 89 are provided.

  The cradle 81 is a portion on which the bobbin B is mounted, and supports the mounted bobbin B in a rotatable manner. The winding drum 82 contacts the outer peripheral surface of the bobbin B or the package P when winding the yarn Y around the bobbin B mounted on the cradle 81 to form the package P. The winding drum 82 is supported by the frame 21 of the spinning unit 2 so as to be rotatable about an axis J1 extending in the left-right direction. The frame 21 is also provided with a yarn accumulating roller 61, a yarn splicing device 34, a yarn monitoring device 35 and the like constituting the spinning unit 2, but these are not shown in FIG.

  The winding drum 82 is connected to a motor (not shown) and is driven to rotate by this motor. When the winding drum 82 rotates, the bobbin B (package P) mounted on the cradle 81 rotates, and the yarn Y is wound around the bobbin B. Further, a traverse groove (not shown) is formed on the surface of the winding drum 82, and when the yarn Y is wound around the bobbin B, the yarn is guided to the traverse groove so that the winding drum 82 Traversed in the axial direction (left-right direction).

  One end of the swing arm 83 is positioned in the vicinity of the left end of the take-up drum 82 and is supported by the frame 21 so as to be swingable about the axis J1. One end of the swing arm 84 is located in the vicinity of the right end of the winding drum 82 and is supported by the frame 21 so as to be swingable about the axis J1. The swing arm 83 and the swing arm 84 are connected to each other by a substantially cylindrical shaft 91 extending in the left-right direction at the center in the length direction. In the present embodiment, the combination of the swing arms 83 and 84 and the shaft 91 corresponds to the “support mechanism” of the present invention.

  In addition, the left end and the right end of the cradle 81 are connected to the other ends of the swing arms 83 and 84, respectively. The cradle 81 is supported by swing arms 83 and 84 so as to be swingable about an axis J2 parallel to the left-right direction. Further, the other end of the swing arm 83 is provided with a connecting portion 83a to which a hook 123 of the moving operation portion 103 described later is connected.

  In the winding unit 33, the swing arms 83 and 84 swing about the axis J1, and the cradle 81 swings about the axis J2. As a result, the cradle 81 is moved as shown in FIGS. It is possible to move between a winding position when winding the yarn Y around the bobbin B shown in FIG. 4 and a work position shown in FIG. 4B for allowing the operator to work on the package P as will be described later. It has become. Further, as can be seen from FIGS. 4A and 4B, the work position is a position below and in front of the winding position. Further, the work position is a position below the winding drum 82. Specifically, the work position is, for example, a position about 30 to 70 cm below the winding position.

  Then, the operator performs work on the package P in a state where the cradle 81 is located at the work position. The operation performed by the operator on the package P is, for example, an operation in which the operator manually pulls out the yarn Y from the package P when the yarn drawing device 70 fails to pull out the yarn Y from the package P. When the cradle 81 is in the winding position, the package P is at a high position, and the operator's hand may not easily reach the package P. Further, in the spinning unit 2 of the present embodiment, the position of the winding unit 33 is high because the case storage unit 44 is disposed below the yarn feeding unit 31, and the operator's hand is particularly difficult to reach the package P. It has a configuration.

  In the present embodiment, the cradle 81 is positioned below the winding position while being positioned at the work position. Therefore, the operator can easily reach the package P. Further, in the present embodiment, the cradle 81 is located in front of the winding position in a state where it is located in the working position. Therefore, when the operator performs an operation on the package P, the package P of the adjacent spinning unit 2 is less likely to get in the way, and the package P is positioned near the work path 5. From these things, in this Embodiment, the operator can perform the operation | work with respect to the package P rather than performing the operation | work with respect to the package P in the state in which the cradle 81 is located in the winding position.

  In the present embodiment, the cradle 81 is located at the work position and is located below and in front of the winding position, so that the work is performed in a plane perpendicular to the left-right direction. The package P to be performed is shifted in position from other packages P. Therefore, the operator can easily grasp the package P that requires work.

  The swing arm 83 is biased by a spring 92 (the “biasing member” of the present invention). More specifically, one end of the spring 92 is fixed to the rear portion of the frame 21 relative to the cradle 81 and the take-up drum 82, and the other end of the spring 92 is attached to the swing arm 83. . The spring 92 is a tension spring and urges the swing arm 83 to the rear side.

  Here, the other end 92b of the spring 92 swings the swing arms 83 and 84 as described above, and moves the cradle 81 between the winding position and the working position as shown in FIG. Are located on a straight line L connecting one end 92a of the spring 92 and the axis J1. In the present embodiment, the position of the cradle 81 in the state of FIG. 5 corresponds to the “predetermined position” of the present invention. When the cradle 81 is shifted from the position shown in FIG. 5 toward the winding position, the other end 92b of the spring 92 is positioned above the straight line L (see, for example, FIG. 8B). On the other hand, when the cradle 81 is shifted from the position of FIG. 5 to the working position side, the other end 92b of the spring 92 is positioned below the straight line L as shown in FIG. That is, in the present embodiment, the swing arm 83 has a portion that moves across the straight line L when the cradle 81 passes through the predetermined position, and the other end 92b of the spring 92 is attached to this portion. ing.

  When the other end 92b of the spring 92 is positioned above the straight line L, the urging force of the spring 92 causes the swing arms 83 and 84 to swing counterclockwise as viewed from the left side (cradle 81). Acting in the direction of moving to the take-up position side). On the other hand, in a state where the other end 92b of the spring 92 is positioned below the straight line L, the urging force of the spring 92 causes the swing arms 83 and 84 to swing in the clockwise direction when viewed from the left side (cradle 81). Acting in the direction of moving to the working position side).

  The stopper 85 is attached to the frame 21 so as to come into contact with the swing arm 83 in a state where the cradle 81 is located at the working position. Thus, when the cradle 81 reaches the working position, the stopper 85 restricts the swing arm 83 from further swinging.

  The rocker 86 is for fixing the cradle 81 at the winding position by restricting the swinging arms 83 and 84 from swinging in a state where the cradle 81 is positioned at the winding position. More specifically, the rocker 86 is located near the shaft 91 in a state where the cradle 81 is located at the winding position as shown in FIGS. The frame 21 is supported so as to be swingable about an axis J3 parallel to the left-right direction. A cylinder 93 is connected to the lower end of the rocker 86. When the cylinder 93 is extended, the rocker 86 swings counterclockwise around the axis J3 as viewed from the left side. When the cylinder 93 is contracted, the rocker 86 swings clockwise around the axis J3 as viewed from the left side.

  When winding is performed in the winding unit 33, as shown in FIG. 6A, the cylinder 93 is contracted, and the upper end portion of the rocker 86 is engaged with the shaft 91. In this state, the swing of the swing arms 83 and 84 is restricted, and the cradle 81 is fixed at the winding position. Thereby, it is possible to prevent the cradle 81 from moving unnecessarily during winding in the winding unit 33. On the other hand, when the cradle 81 is moved from the winding position to the work position, the cylinder 93 is extended. Then, as shown in FIG. 6B, the rocker 86 is disengaged from the shaft 91, and the swing arms 83 and 84 can swing. In this embodiment, the rocker 86 is engaged with the shaft 91 that connects the swing arm 83 and the swing arm 84, but the rocker 86 is one of the swing arms 83 and 84. Alternatively, it may be engaged with the cradle 81.

  The contact pressure adjusting unit 87 is for adjusting the contact pressure between the package P and the winding drum 82 in accordance with the winding thickness of the package P or the like. More specifically, the contact pressure adjusting portion 87 includes a plate cam 94 and a cylinder 95 as shown in FIGS. 3, 7A, and 7B. The plate cam 94 is a substantially fan-shaped plate-like member, and the outer peripheral surface thereof is a cam surface 94a. The plate cam 94 is fixed to the base end portion of the cradle 81, and can swing integrally with the cradle 81 about the axis J2. The tip of the cylinder 95 is in contact with the cam surface 94a. Then, by applying pressure to the cylinder 95, the plate cam 94 is centered on the axis J2 when viewed from the direction of FIGS. 7A and 7B in accordance with the inclination angle of the contact portion of the cam surface 94a with the cylinder 95. The bobbin B mounted on the cradle 81 is urged so as to approach the take-up drum 82, and conversely, the plate cam 94 is swung counterclockwise about the axis J2. The bobbin B attached to the cradle 81 can be urged away from the take-up drum 82 by being moved.

  When the winding unit 33 forms the package P by winding the yarn Y around the bobbin B, as shown in FIGS. 7 (a) and 7 (b), the cylinder 95 is matched with the winding thickness of the package P. By applying pressure to the cylinder 95, the inclination angle of the cam surface 94a in contact with the cylinder 95 is gradually changed. Thereby, a fixed contact pressure can be applied to the package P during winding.

  The first sensor 88 is provided in a portion of the frame 21 adjacent to the swing arm 84 in a state where the cradle 81 is located at the winding position. The first sensor 88 detects whether or not the cradle 81 is located at the winding position depending on whether or not it is close to the swing arm 84. The second sensor 89 is close to the swing arm 84 in a state where the cradle 81 of the frame 21 is located at the working position. The second sensor 89 detects whether or not the cradle 81 is located at the work position depending on whether or not it is close to the swing arm 84.

<Working cart>
Next, the work cart 3 will be described. As described above, the work carriage 3 is movable in the left-right direction along the guide rails 11 and 12. More specifically, as shown in FIGS. 4A and 4B, the work carriage 3 includes drive wheels 111 and 112 that are in contact with the upper surfaces of the guide rails 11 and 12, respectively. The drive wheels 111 and 112 are connected to a motor (not shown). When the motor is driven, the drive wheels 111 and 112 rotate and the work carriage 3 moves in the left-right direction along the guide rails 11 and 12. . Further, the work carriage 3 is provided with auxiliary wheels 113 that sandwich the guide rail 11 from above and below with the drive wheels 111 and two auxiliary wheels 114 and 115 that sandwich the guide rail 11 from the front-rear direction. The work cart 3 is provided with auxiliary wheels 116 that sandwich the guide rail 12 from above and below with the drive wheels 112. As a result, it is possible to prevent the work carriage 3 from vibrating in the vertical direction and the front-rear direction and being displaced in the front-rear direction while traveling.

  As shown in FIGS. 1, 4 (a) and 4 (b), the work carriage 3 is provided with a doffing unit 102 and a movement operation unit 103. The doffing unit 102 is used for removing the package P that has been wound up from the cradle 81 and doffing the cradle 81 with a new bobbin B in each spinning unit 2. The doffing unit 102 is a well-known one described in, for example, the above-described Patent Document 1, and therefore, detailed description thereof is omitted here.

  The movement operation unit 103 is located on the left side of the doffing unit 102. The movement operation unit 103 is for performing a movement operation for moving the cradle 81 to the work position with respect to each spinning unit 2. The movement operation unit 103 includes two cylinders 121 and 122 (the “drive source” of the present invention) and a hook 123 (the “connection unit” of the present invention). The cylinder 121 extends substantially in the vertical direction. The cylinder 121 can swing around an axis J4 that is located at the upper end of the cylinder 121 and is parallel to the left-right direction. The cylinder 122 is attached to the cylinder 121 and extends substantially in the front-rear direction. Then, by expanding and contracting the cylinder 122, the cylinder 121 can be swung around the axis J4. The hook 123 is attached to the lower end portion of the cylinder 121 and can be moved in the expansion / contraction direction of the cylinder 121 by expansion / contraction of the cylinder 121.

  In this embodiment, when the doffing unit 102 performs doffing, the work carriage 3 is moved to a position where the doffing unit 102 faces the package P in the front-rear direction (hereinafter referred to as a doffing position). In the work carriage 3, the hook 123 of the movement operation unit 103 is located at the same position as the connection part 83 a of the swing arm 83 in the left-right direction while being in the doffing position. That is, the movement operation unit 103 is provided at a portion of the work carriage 3 where a movement operation described later can be performed in a state where the movement operation unit 3 is located at the doffing position.

  In addition, the work carriage 3 does not overlap the spinning unit 2 and the package P in the left-right direction when the cradle 81 is located at the winding position and when it is located at the work position. Therefore, even when the cradle 81 is located at the work position, the work carriage 3 can be moved in the left-right direction.

<Operation of moving operation unit>
Next, a method for causing the movement operation unit 103 to perform a movement operation for moving the cradle 81 from the winding position to the work position will be described. In order to move the cradle 81 from the winding position to the work position, first, the control device 16 moves the work carriage 3 to the doffing position as shown in FIG. Then, as shown in FIG. 8A, the control device 16 drives the cylinder 122 to swing the cylinder 121 and extends the cylinder 121 to connect the hook 123 to the connecting portion 83a.

  Subsequently, as shown in FIG. 8B, the control device 16 contracts the cylinders 121 and 122, thereby pulling the connecting portion 83a with the hook 123 and swinging the swing arms 83 and 84 about the axis J1. Let Subsequently, as shown in FIG. 9A, the control device 16 extends the cylinder 121 and further contracts the cylinder 122, thereby pushing the connecting portion 83a with the hook 123, and swinging arm 83 about the axis J1, 84 is swung to move the cradle 81 to the working position. At this time, the swing arms 83 and 84 swing until the swing arm 83 contacts the stopper 85.

  After that, the control device 16 extends the cylinder 122 and swings the cylinder 121 in the clockwise direction as viewed from the left side, thereby removing the hook 123 from the connecting portion 83a and further contracting the cylinders 121 and 122. The moving operation unit 103 is returned to the original position. Here, in the present embodiment, when the swing arm 84 is detected by the second sensor 89, the control device 16 removes the hook 123 from the connecting portion 83a as described above, and moves the moving operation portion 103. Return to the original position.

  Here, in the state where the cradle 81 is located at the working position, the other end 92b of the spring 92 is located below the straight line L as described above. Thereby, the biasing force of the spring 92 acts in the clockwise direction when the swinging arms 83 and 84 are viewed from the left side, that is, in the direction of pressing the swinging arm 83 against the stopper 85. Therefore, even if the hook 123 is removed from the connecting portion 83a, the cradle 81 is maintained in a state where it is located at the work position.

  Next, a method for returning the cradle 81 located at the work position to the winding position will be described. In order to return the cradle 81 located at the work position to the winding position, the operator pushes the package P upward as shown in FIG. 9B. When the package P is pushed up until the other end 92b of the spring 92 is above the straight line L, the urging force of the spring 92 is counterclockwise when the swing arms 83 and 84 are viewed from the left side, that is, the winding. Acts in the direction toward the position. As a result, the cradle 81 returns to the winding position by the biasing force of the spring 92.

<Control of work carts, etc. during operation of spinning machine>
Next, control of the work cart 3, the doffing unit 102, the moving operation unit 103, the notification unit 17 and the like by the control device 16 will be described. When the spinning machine 1 is activated, the control device 16 starts processing for controlling the work carriage 3, the doffing unit 102, the moving operation unit 103, the notification unit 17, and the like as shown in the flowchart of FIG. . Then, while the spinning machine 1 is operating (S101: YES), the control device 16 executes the processes of S102 to S110 described below, and when the spinning machine 1 is stopped (S101: NO), This process ends.

  Here, when the spinning machine 1 is activated, the work carriage 3 is located at the home position on the right side of the plurality of spinning units 2 as indicated by broken lines in FIGS. 1 (a) and 1 (b), for example. Although the detailed description is omitted, the spinning machine 1 can remove lint attached to the work cart 3 during doffing while the work cart 3 is located at the home position. Yes. The home position may be on the left side of the plurality of spinning units 2.

  Further, during the operation of the spinning machine 1, each spinning unit 2 sends a ball to the control device 16 when the winding unit 33 completes winding the yarn Y onto the bobbin B and completes the package P. Send a doffing signal requesting lifting. Further, during the operation of the spinning machine 1, each spinning unit 2 sends the control device 16 when the operator needs to work on the package P, such as when the yarn drawing device 70 fails to draw the yarn Y. An abnormal signal is sent to the operator to request work.

  Next, the process of S102-S110 is demonstrated in detail. While neither the doffing signal nor the abnormality signal is input from the spinning unit 2 (S102: NO, S103: NO), the control device 16 keeps the work carriage 3 at the home position.

  When the doffing signal is input (S102: YES), the control device 16 moves the work carriage 3 to the doffing position corresponding to the spinning unit 2 (S104), and doffs the doffing unit 102. (S105). Then, after completion of doffing, the work carriage 3 is moved to the home position (S106), and the process returns to S101.

  On the other hand, when an abnormal signal is input (S103: YES), the control device 16 moves the work cart 3 to the doffing position (S107). Then, the cradle 81 is moved to the work position by operating the movement operation unit 103 as described above (S108). Subsequently, the control device 16 retracts the work carriage 3 by moving it to the home position (S109), and causes the notification unit 17 to notify the operator that an abnormality has occurred (S110). The operator receives a notification from the notification unit 17 and performs an operation on the package P. Then, after the operation on the package P is completed, the operator lifts the package P upward as described above to return the cradle 81 to the winding position.

  As described above, in the present embodiment, after the cradle 81 is moved to the work position, the notification unit 17 is notified. Therefore, the operator receives a notification from the notification unit 17 in a state where the cradle is moved to the work position, and can easily grasp the package P that needs the work. Further, after the cradle 81 is moved to the work position, the work carriage 3 is moved to the home position to be retracted, so that the work carriage 3 does not get in the way for the operator to work on the package P. . In S108, the work carriage 3 may be retracted to a position other than the home position.

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

  In the above-described embodiment, the work position is located below the winding position and the winding drum 82 and ahead of the winding position, but is not limited thereto. For example, the working position may be a position below the winding position and may be the same height as the winding drum 82 or a position above the winding drum 82.

  Further, depending on the layout of each part of the spinning unit 2, the work position may be a position directly below the winding position, or may be a position below and behind the winding position. Alternatively, the work position may be the same height as the winding position and a position shifted from the winding position to the front side or the rear side.

  In the above-described embodiment, when the doffing unit 102 doffs the spinning unit 2, and when the moving operation unit 103 moves the cradle 81 of the spinning unit 2, the work cart 3 Although the position in the left-right direction is the same, it is not limited to this. For example, when the cradle 81 of the spinning unit 2 having the moving operation unit 103 is moved, the position of the work carriage 3 in the left-right direction is such that the doffing unit 102 is different from the spinning unit 2 (adjacent spinning units 2). It may be the same as the position in the left-right direction of the work cart 3 when doffing is performed with respect to 2). Alternatively, the horizontal position of the work cart 3 when the movement operation unit 103 moves the cradle 81 is set in the horizontal direction of the work cart 3 when the doffing unit 102 performs doffing with respect to any spinning unit 2. It may be different from the position.

  In the above-described embodiment, the work cart 3 includes the doffing unit 102 and the movement operation unit 103. However, the present invention is not limited to this. For example, the spinning machine 1 may include a work cart provided with the doffing unit 102 and a work cart provided with the movement operation unit 103 separately. Alternatively, the spinning machine 1 includes a work cart provided with the movement operation unit 103, but may not include the doffing unit 102. In this case, for example, the operator performs doffing manually with the cradle 81 positioned at the work position.

  In the above-described embodiment, when the cradle 81 reaches the working position, the swing arm 83, 84 is prevented from further swinging by the biasing force of the spring 92 by the stopper 85. Not limited. For example, in a state where the stopper 85 is not provided and the cradle 81 is located at the working position, a force acting on the swing arm 83 from the spring 92 and a force other than this (such as gravity) acting on the swing arm 83 are generated. It may be balanced.

  Further, in the above-described embodiment, the rocking arms 83 and 84 and the cradle 81 are fixed by the rocker 86 in a state where the cradle 81 is positioned at the winding position, but the rocker 86 may not be provided. For example, when the cradle 81 and the swing arms 83 and 84 are sufficiently heavy, the cradle 81 does not move unnecessarily even without the locker 86.

  In the above-described embodiment, when the cradle 81 moves between the winding position and the working position, the portion of the swing arm 83 where the other end 92b of the spring 92 is attached moves across the straight line L. However, it is not limited to this. For example, the positional relationship between the winding position and the work position may be different from the above-described embodiment in that the other end 92b of the spring 92 is always positioned above the straight line L. In this case, even when the cradle 81 is located in any position in the movement range between the winding position and the work position, the biasing force of the spring 92 is in a direction in which the cradle 81 is directed toward the winding position. Works. In this case, for example, by providing a locker for fixing the cradle 81 to the work position, the cradle 81 may not be returned to the winding position by the biasing force of the spring 92 during the work. In this case, after the work on the package P is completed, the cradle 81 can be returned to the winding position by the biasing force of the spring 92 by releasing the lock by the locker.

  In the above-described embodiment, the movement operation unit 103 swings the swing arm 83 by connecting the hook 123 to the connecting portion 83a of the swing arm 83 and then expanding and contracting the cylinders 121 and 122. The cradle 81 is moved to the work position, but the present invention is not limited to this. For example, the cradle 81 may be provided with a connecting portion that is connected to the hook 123. Further, the moving operation unit is configured so that the cradle 81 is directed to the working position on the oscillating arms 83 and 84 or the cradle 81 by a configuration other than expanding and contracting the cylinder with the hook connected to the oscillating arms 83 and 84. You may give the force of the direction to dodge.

  Furthermore, the moving operation unit is not limited to applying a force in the direction of moving the cradle 81 toward the work position to the swing arms 83 and 84 or the cradle 81. For example, instead of the spring 92 (see FIG. 3 and the like), a spring that biases the cradle 81 in the direction from the winding position toward the working position is provided, and the moving operation unit is made to be the swing arms 83 and 84 by the rocker 86. It is good also as what cancels | releases fixation of. In this case, the spinning unit 2 does not need the cylinder 93. In this case, the operation of releasing the fixation of the swing arms 83 and 84 by the rocker 86 corresponds to the “moving operation” of the present invention.

  Alternatively, each spinning unit 2 has a drive source for swinging the swing arms 83 and 84 and a switch for driving the drive source, and the moving operation unit operates the switch and the like. Thus, the drive source may be driven. In this case, the operation of the switch or the like corresponds to the “movement operation” of the present invention.

  In the above-described embodiment, the rotating shaft of the winding drum 82 and the swinging shafts of the swinging arms 83 and 84 are the same axis J1, but this is not restrictive. The swing arms 83 and 84 may swing about an axis different from the rotation axis of the winding drum 82.

  Further, the support mechanism that supports the cradle so as to be movable between the winding position and the work position is not limited to having a swing arm connected to the cradle. In one modification, as shown in FIG. 11, the cradle 151 is supported by a slide mechanism 152 (the “support mechanism” of the present invention). The slide mechanism 152 includes a slider 153 and a guide rail 154. The slider 153 is connected to the base end portion of the cradle 151. Further, the slider 153 is provided with a connecting portion 153a for connecting with the hook 123 (see FIG. 4A, etc.) of the moving operation portion 103. The guide rail 154 extends along the front-rear direction, and is inclined with respect to the front-rear direction so as to be positioned on the lower side toward the front side. The slider 153 is movable along the guide rail 154.

  Then, with the slider 153 positioned at the upper left portion of the guide rail 154, the bobbin or package P mounted on the cradle 151 contacts the winding drum (not shown) (the cradle 151 is positioned at the winding position). To do). When the slider 153 is moved to the lower right part of the guide rail 154 by appropriately expanding and contracting the cylinders 121 and 122 after connecting the hook 123 to the connecting portion 153a from this state, the cradle 151 is moved from the winding position. Move to the front and lower work position. Since the working position is located below the winding position, gravity can be used when the cradle 151 is moved from the winding position to the working position, and the force applied to the slider 153 can be reduced. it can.

  In addition, the configuration for moving the cradle to which the bobbin B (package P) is mounted between the winding position and the working position includes a mechanism using the swing arm as in the above-described embodiment, and the above modification. The slide mechanism may be different from any of the slide mechanisms.

  In the above-described embodiment, the control device 16 moves the cradle 81 to the work position and then retracts the work cart 3 to the home position. However, the present invention is not limited to this. For example, a sensor for detecting that an operator or the like has approached the work carriage 3 may be provided, and the work carriage 3 may be retracted when the sensor detects that the operator has approached.

  Alternatively, after the cradle 81 is moved from the winding position to the work position by the movement operation unit 103, the work carriage 3 may remain stopped. For example, the position of the work carriage 3 when the cradle 81 is moved by the movement operation unit 103 is different from the position of the work carriage 3 when the doffing is performed, and the operation when the cradle 81 is moved by the movement operation unit 103. When the position of the carriage 3 is a position that does not interfere with the operation on the package P by the operator, the work carriage 3 does not have to be retracted. Furthermore, when the work carriage 3 is not retracted after the cradle 81 is moved to the work position, the work carriage 3 may overlap the package P in the left-right direction while the cradle 81 is located at the work position. .

  Further, in the above-described embodiment, after the cradle 81 is moved to the work position, the notification unit 17 is notified to the operator. However, the present invention is not limited to this. For example, the notification unit 17 may be notified at the same time when the cradle 81 is moved. Alternatively, the notification unit 17 may be notified before the cradle 81 is moved. In this case, for example, the operator grasps the package P in need of work based on the display of the notification unit 17.

  In the above-described embodiment, the winding unit 33 detects that the cradle 81 is positioned at the winding position, and the cradle 81 is positioned at the working position. Although the second sensor 89 for detection is provided, at least one of these sensors may be omitted.

  In the above example, the movement operation unit moves the cradle from the winding position to the work position, but the present invention is not limited to this. For example, when the engagement of the rocker 86 with the shaft 91 is released, the position of the cradle 81 may slightly deviate from the winding position, such as when the cradle 81 is slightly lifted. In this case, the moving operation unit moves the cradle 81 from the position slightly shifted from the winding position to the working position.

  In the above-described embodiment, the cradle 81 is returned to the winding position by the urging force of the spring 92 when the operator lifts the package P upward. However, the present invention is not limited to this. For example, the movement operation unit 103 may return the cradle 81 from the work position to the winding position after the operator completes the work on the package P. In this case, the spring 92 may not be provided.

  Moreover, although the example which applied this invention to the spinning machine which performs spinning was demonstrated above, it is not restricted to this. For example, as described in JP-A-2016-172602, a yarn winding machine other than a spinning machine such as an automatic winder that unwinds a yarn from a yarn feeding bobbin and winds another winding bobbin to form a package. The present invention can also be applied to.
