An apron belt 16A is provided for the middle roller vs. 16 top rollers. An apron belt 16B is provided for the bottom roller of the middle roller vs. 16.

The air spinning device 7 twists the fiber bundle F drafted by the draft device 6 by a swirling air flow to generate a yarn Y. More specifically (however, not shown), the air spinning apparatus 7 has a spinning chamber, a fiber guide portion, a swirling air flow generating nozzle, and a hollow guide shaft body. The fiber guide unit guides the fiber bundle F supplied from the draft device 6 on the upstream side into the spinning chamber. The swirling air flow generating nozzle is arranged around the path through which the fiber bundle F travels. Swirling air flow generation By injecting air from the nozzle, swirling air flow is generated in the spinning chamber. By this swirling air flow, each fiber end of the plurality of fibers constituting the fiber bundle F is inverted and swirled. The hollow guide shaft guides the yarn Y from the spinning chamber to the outside of the air spinning apparatus 7.

The yarn monitoring device 8 is arranged between the air spinning device 7 and the yarn storage device 50. The thread monitoring device 8 monitors the state of the traveling thread Y and detects the presence or absence of a thread defect. The thread monitoring device 8 also detects thread breakage and the like.

The tension sensor 9 measures the tension of the traveling yarn Y between the air spinning device 7 and the yarn storage device 50, and transmits a tension measurement signal to the unit controller.

When the unit controller determines that there is an abnormality based on the detection result of the yarn monitoring device 8 and / or the tension sensor 9, the yarn Y is cut in the spinning unit 2. Specifically, the supply of air to the air spinning apparatus 7 is stopped, and the production of the yarn Y is interrupted, so that the yarn Y is cut. Alternatively, the thread Y may be cut by a cutter provided separately.

The waxing device 12 applies wax to the yarn Y between the yarn storage device 50 and the take-up device 13. When the wax is not applied to the yarn Y, the yarn Y may be spun with the wax removed from the waxing device 12.

The yarn storage device 50 takes the slack of the yarn Y between the air spinning apparatus 7 and the winding apparatus 13. The yarn storage device 50 has a function of stably pulling out the yarn Y from the air spinning apparatus 7, and prevents the yarn Y from loosening by retaining the yarn Y sent out from the air spinning apparatus 7 during the yarn splicing operation by the yarn splicing trolley 3. It has a function of preventing and a function of preventing fluctuations in the tension of the yarn Y on the downstream side of the yarn storage device 50 from being transmitted to the air spinning device 7.

The take-up device 13 winds the thread Y on the bobbin B to form the package P. The take-up device 13 has a cradle arm 21, a take-up drum 22, and a traverse guide 23.

The cradle arm 21 rotatably supports the bobbin B. The cradle arm 21 is swingably supported by a support shaft 24, and brings the surface of the bobbin B or the surface of the package P into contact with the surface of the take-up drum 22 at an appropriate pressure. A drive motor (not shown) provided on the end frame 5 simultaneously drives the take-up drums 22 of the plurality of spinning units 2. As a result, the bobbin B or the package P is rotated in the winding direction in each spinning unit 2. The traverse guide 23 of each spinning unit 2 is provided on a shaft 25 shared by the plurality of spinning units 2. The drive motor of the end frame 5 reciprocates the shaft 25 in the rotation axis direction of the take-up drum 22, and the traverse guide 23 traverses the thread Y with a predetermined width with respect to the rotating bobbin B or the package P.

When the yarn Y is cut in a certain spinning unit 2 or the yarn Y is broken for some reason, the yarn splicing carriage 3 travels to the spinning unit 2 and performs a yarn splicing operation. The thread splicing carriage 3 includes a suction pipe 31, a thread splicing device 37, and a suction mouse 38.

The suction mouse 38 is rotatably supported by the support shaft 38A, captures the thread Y from the winding device 13, and guides the thread Y to the thread joining device 37. The thread splicing device 37 joins the guided threads Y together.

The yarn splicing device 37 reverses the yarn Y from the package P to the air spinning device 7 instead of the configuration in which the yarns Y are spliced to each other, and performs a draft operation by the draft device 6 and a spinning operation by the air spinning device 7. By restarting, the thread Y may be in a continuous state.

When the thread splicing carriage 3 performs the thread splicing operation, the package P is rotated (reversely rotated) in the counterwinding direction. The thread joint carriage 3 is provided with a reverse rotation roller.

The bobbin trolley 4 supplies the bobbin B supplied from the bobbin stocker 90, which will be described later, to the cradle arm 21 to prepare for winding the thread Y, and the bobbin set operation and the fully wound package P to the cradle arm 21. Perform the bobbin operation to remove from. When the fully wound package P is completed in one spinning unit 2, the bobbin 4 travels to one spinning unit 2 on the traveling path 1B formed in the main body frame by the control signal from the machine base control device 11. Then stop, and perform both the hoisting operation and the bobbin setting operation. The bogie 4 mainly includes an accommodating portion 41, a bobbin supply mechanism 42, a cradle operation arm 43, and a suction pipe 44.

The accommodating section 41 accommodates the bobbin B supplied from the bobbin stocker 90. The bobbin supply mechanism 42 supplies the bobbin B to the cradle arm 21. The suction pipe 44 captures the thread Y discharged from the air spinning device 7 by sucking it with a suction unit, and guides the captured thread Y to the winding device 13. The cradle operation arm 43 is an operation of opening the cradle arm 21 in order to remove the fully wound package P from the winding device 13, or an operation of closing the cradle arm 21 in order to attach a new bobbin B to the cradle arm 21. I do.

The bobbin stocker 90 is arranged at the end opposite to the end frame 5 as shown in FIG. The bobbin stocker 90 includes a bobbin accommodating portion 91, a bobbin intake outer 93, a bobbin direction changing mechanism 70, a bobbin transport mechanism 85, and a bobbin delivery mechanism 87.

The bobbin accommodating portion 91 has a plurality of pegs 91A which are rod-shaped members to which the bobbin B can be attached. As shown in FIG. 3, the bobbin B for winding the thread Y is configured as a tubular body (core tube). In the present embodiment, when the bobbin B is viewed from the front, it is formed in a divergent shape that spreads from one end Ba to the other end Bb in the axial direction. In other words, the bobbin B is formed in a tapered shape from the other end Bb toward one end Ba. That is, the diameter of one end Ba of the bobbin B is smaller than the diameter of the other end Bb in the axial direction. Hereinafter, one end Ba is also referred to as a small diameter end Ba, and the other end Bb is also referred to as a large diameter end Bb.

The bobbin accommodating portion 91 is configured to be able to store the bobbin B so that its axial end faces the work passage side (the front side of the paper in FIG. 1). The bobbin B is supported by the peg 91A in a state where the small diameter end Ba is directed forward and the axis is horizontal or substantially horizontal.

The front side (front side) of the bobbin accommodating portion 91 is open, and the tip of each peg 91A is configured to be exposed on the front surface side of the bobbin accommodating portion 91. The peg 91A faces the front side.

The bobbin accommodating portion 91 has an endless chain 91B that is circulated and driven in a plane (vertical plane) substantially orthogonal to the longitudinal direction of the peg 91A. The plurality of pegs 91A are fixed to the endless chain 91B. Therefore, by circulating the endless chain 91B continuously or intermittently in one direction, the bobbin B attached to the peg 91A can be conveyed along the longitudinal direction of the endless chain 91B.

A bobbin take-out outer 93 is provided in the middle of the bobbin B transport path in the bobbin accommodating portion 91. The bobbin take-out outer 93 is composed of the tip of a lot of air cylinders (not shown) driven by air supplied from an air supply source. The bobbin B is removed from the peg 91A by being pushed forward by the bobbin removal outside 93. Specifically, the bobbin take-out outer 93 pushes the bobbin B toward the bobbin direction changing mechanism 70. The bobbin take-out outer 93 may be configured by a pusher connected to an air cylinder.

As shown in FIGS. 3, 4, 5, 5, etc., the bobbin direction changing mechanism 70 changes the direction of the bobbin supplied from one direction (specifically, the bobbin taking outside 93) to change the direction of the bobbin B to the other. It is configured to pass in the direction of. Specifically, the bobbin direction changing mechanism 70 provides the bobbin B from a direction different from that of the first support portion 75 and the first support portion 75 that support one end of the bobbin B in the axial direction (small diameter end Ba in this embodiment). An air cylinder AC (drive) that moves the bobbin support portion having the second support portion 73 to be supported and the bobbin support portion to the receiving position RP (FIG. 5 (A)) and the discharging position DP (FIG. 5 (C)). Equipment) and.

The first support portion 75 and the second support portion 73 are connected so as to move integrally by driving the air cylinder AC. For example, at least a part of the first support portion 75 and the second support portion 73 is integrally formed.

When the bobbin B is delivered from the bobbin removal outside 93, the bobbin direction changing mechanism 70 stands up with the large diameter end Bb facing upward and the small diameter end Ba facing downward, as shown in FIG. The bobbin B is supported in a state (the standing state includes not only the state of standing vertically but also the state of standing diagonally with respect to the vertical line).

At the tip of the first support portion 75 (the end opposite to the rotation center of the bobbin support portion), a protrusion 75S (slip prevention portion) extending along the front-rear direction of the first support portion 75 is provided. Has been done. Even if the small diameter end Ba of the bobbin B supplied from the bobbin removal outside 93 slips on the first support portion 75 and is about to fall from the first support portion 75 at an unintended timing, the small diameter of the bobbin B is due to the protruding portion 75S. The movement of the end Ba can be regulated. The angle and / or shape of the protrusion 75S with respect to the first support portion 75 shown in FIGS. 3 and 4 is an example and can be changed as appropriate.

A sheet-shaped rubber (buffer member) is attached to the surface of the first support portion 75. As a result, it is possible to prevent the bobbin B supplied to the bobbin direction changing mechanism 70 from being damaged by coming into contact with the first support portion 75. The sheet-shaped rubber is configured so that both sides thereof can be used. If the surface of the rubber has deteriorated, the operator may replace the side that becomes the surface side of the rubber, and if both sides are worn, the rubber may be discarded and replaced with new rubber.

As shown in FIGS. 1 and 3, the bobbin transfer mechanism 85 includes a drive roller 85a, a driven roller 85b, a belt 85c wound around the drive roller 85a and the driven roller 85b, and a pair of guides 83 and 83. is doing. The drive roller 85a is driven by a motor (not shown). The belt 85c rotates with the rotation of the drive roller 85a in the arrow direction d, and conveys the bobbin B mounted on the belt 85c in the arrow direction e. The pair of guides 83, 83 are arranged along the transport direction, and restrict the movement of the bobbin B in the belt width direction (front-back direction).

As shown in FIG. 1, the bobbin delivery mechanism 87 is arranged on the downstream side in the transport direction of the bobbin transport mechanism 85. The bobbin delivery mechanism 87 delivers the bobbin B delivered from the bobbin transport mechanism 85 to the bobbin bogie 4 stopped at the receiving position P1. The bobbin delivery mechanism 87 has a belt conveyor driven by a drive roller (not shown).

Next, the operation of the bobbin stocker 90 will be described. As shown in FIG. 1, the bobbin B conveyed to the bobbin removal outside 93 by the bobbin accommodating portion 91 is pushed forward by the bobbin removal outside 93. As shown in FIG. 5A, the bobbin B extruded by the bobbin removal outside 93 is delivered to the bobbin direction changing mechanism 70 by falling with the small diameter end Ba facing downward. That is, since the first support portion 75 is arranged below the position where the bobbin B is pushed out by a predetermined distance (distance equal to or greater than the total length of the bobbin B), the bobbin B is in a posture of extending in the front-rear direction before delivery. , It is delivered in a posture that extends in the vertical direction. The bobbin B delivered to the bobbin direction change mechanism 70 is temporarily supported in an upright state by the small diameter end Ba being supported by the first support portion 75 and the large diameter end Bb being supported by the second support portion 73. Will be done.

After that, the air cylinder AC is driven at a predetermined timing, and the bobbin support portion passes from the receiving position RP shown in FIGS. 4 and 5 (A) to the position shown in FIG. Move to the discharge position DP shown in C). The predetermined timing is measured by a timer (not shown). The drive of the air cylinder AC is controlled by the machine base control device 11.

By moving the bobbin support portion to the discharge position DP, the bobbin B rotates in the left direction, which is the delivery direction, about the small diameter end Ba as an axis. That is, the bobbin B rotates counterclockwise. Since the position of the large diameter end Bb of the bobbin B when the bobbin B is delivered to the belt 85c is higher than the position of the belt 85c, the bobbin B has a large diameter when falling from the first support portion 75. It is delivered to the bobbin transfer mechanism 85 with the end Bb facing to the left and the small diameter end Ba facing to the right. The position of the large diameter end Bb of the bobbin B and the position of the belt 85c when the bobbin B is delivered to the belt 85c may be set to the same height, and the bobbin B may be delivered so as not to fall.

The bobbin transfer mechanism 85 to which the bobbin B is delivered from the bobbin direction changing mechanism 70 conveys the bobbin B to the left and delivers it to the bobbin delivery mechanism 87. The bobbin delivery mechanism 87 delivers the bobbin B to the bobbin trolley 4.

The bobbin direction changing mechanism 70 further includes a valve (prohibition device) (not shown) that prohibits the movement of the bobbin support portion by the air cylinder AC. For example, when the operator performs maintenance on the bobbin turning mechanism 70, the valve can be closed to prevent the air cylinder AC from operating. When the bobbin direction change mechanism 70 changes the direction of the bobbin B, the valve is kept open.

The bobbin direction changing mechanism 70 of the present embodiment described above is configured to change the direction of the bobbin B supplied from one direction and deliver the bobbin B to another direction (for example, the belt 85). The bobbin direction change mechanism 70, the first support portion 75 that supports one end (small diameter end Ba) of the bobbin B in the axial direction, and the second support portion 73 that supports the bobbin B from a direction different from that of the first support portion 75. The bobbin support portion is provided with an air cylinder AC for moving the bobbin support portion to the receiving position RP and the discharging position DP.

As a result, the bobbin B is positively moved to the discharge position DP by the air cylinder AC, so that the bobbin B can be reliably discharged.

The bobbin direction changing mechanism 70 further includes a valve that prohibits the movement of the bobbin support portion by the air cylinder AC. This improves the maintainability of the bobbin direction changing mechanism 70.

The bobbin direction changer 70 further includes a protrusion 75S provided on the first support portion 75. This makes it possible to prevent the bobbin B from slipping on the first support portion 75 and not turning the bobbin B.

The bobbin direction changer 70 further includes a sheet-shaped rubber provided at a portion where the first support portion 75 supports the bobbin B. As a result, it is possible to prevent the bobbin B supplied to the bobbin turning mechanism 70 from being damaged by coming into contact with the bobbin turning mechanism 70.

The bobbin direction changer 70 further includes a timer that determines the timing for driving the air cylinder AC. As a result, the air cylinder AC can be driven at an appropriate timing.

The bobbin stocker 90 includes a bobbin accommodating portion 91 for accommodating the bobbin B, a bobbin taking outer 93 for removing the bobbin B from the bobbin accommodating portion 91, a bobbin turning mechanism 70 for receiving the bobbin B removed by the bobbin taking outer 93, and a bobbin turning mechanism 70. To be equipped with.

As a result, the bobbin B accommodated in the bobbin accommodating portion 91 can be converted in a desired direction.

The bobbin stocker 90 is provided on the downstream side of the bobbin direction changing mechanism 70 in the moving direction of the bobbin B, and detects that the transport device 85 for transporting the bobbin B and the bobbin B have been transported to a predetermined position by the transport device 85. It includes a detection device (not shown) and a machine base control device 11 that controls an air cylinder AC so as to move the bobbin support portion from the discharge position DP to the receiving position RP when the detection device detects the bobbin B.

As a result, it is possible to reliably avoid a situation in which the bobbin B discharged earlier by the bobbin direction changing mechanism 70 collides with the bobbin B discharged later.

In the above embodiment or modification, the tension sensor 9 may be arranged on the upstream side of the thread monitoring device 8 in the traveling direction of the thread Y. In the spinning unit 2, the waxing device 12, the tension sensor 9, and the yarn monitoring device 8 may be omitted.

In FIG. 1, the spinning machine 1 is shown to wind a cone-shaped package P, but it is also possible to wind a cheese-shaped package (a shape having the same diameter in the axial direction). That is, although the example in which the cone-shaped bobbin B is used has been described, a cheese-shaped bobbin B may be used. The cheese-shaped bobbin B also has directionality. Even in this case, the bobbin direction changing mechanism 70 can deliver the bobbin in a state where one end in the axial direction of the bobbin always faces a predetermined direction. For example, the bobbin can be handed over with the upper end of the bobbin supported in an upright position always facing to the left.

The bobbin direction changing mechanism 70 of the above embodiment or a modification can be applied not only to a spinning machine but also to other thread winders such as an automatic winder and an open-end spinning machine.
