Description

Textile machine

Technical Field

The present invention relates to a textile machine.

Background

In the following description, japanese patent application laid-open No. 2017-77970 is sometimes referred to as patent document 1.

Conventionally, a textile machine having a yarn winding section for winding a spun yarn around a package is known. Patent document 1 discloses such a textile machine.

The textile machine of patent document 1 is configured to produce a cross-wound package by winding yarn unwound from a spun yarn. The textile machine is provided with a suction nozzle supported rotatably. After the winding is interrupted, the suction nozzle turns around to receive the end of the yarn wound on the package.

In the textile machine of patent document 1, the interval between the suction port of the suction nozzle stopped for receiving the yarn and the cross-wound package can be adjusted by changing the position at which the suction nozzle is stopped on the revolving rail.

In patent document 1, in order to adjust the interval between the suction port of the suction nozzle stopped for receiving the yarn and the cross-wound package, the suction nozzle is changed in position in the direction along the revolving track. Depending on the material of the device, the structure for attaching the parts, and the like, it may be difficult to sufficiently achieve the accuracy of the positional relationship between the yarn winding portion forming the package and the suction port of the suction nozzle by merely adjusting the position in the above-described direction.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and an object thereof is to provide a textile machine capable of adjusting a position of a suction nozzle driving unit.

The means for solving the problems and the effects thereof will be described as described above.

According to an aspect of the present invention, there is provided a textile machine configured as follows. That is, the textile machine includes a yarn winding mechanism and a yarn drawing device. The yarn winding mechanism winds the yarn to form a package. The yarn pulling device pulls out yarn from the package. The yarn pulling device includes a main body and a yarn catching portion. The main body is formed in an elongated shape and is provided rotatably about one end thereof as a rotation center. The yarn catching portion is provided at an end of the main body portion on a side away from the rotation center. The textile machine is provided with a position adjusting mechanism for adjusting the position of the rotation center of the main body.

Thereby, the position of the rotation center of the main body (and the catching position of the yarn catching portion) can be adjusted to an appropriate position.

In the above-described textile machine, the following structure is preferable. That is, the yarn winding mechanism includes a contact roller that rotates in contact with the package. The position adjusting mechanism adjusts a distance between the yarn catching portion and the contact roller when the yarn catching portion of the yarn drawing device is positioned at a yarn catching position by moving a position of a rotation center of the main body portion.

Thus, by adjusting the rotation center of the main body portion, the position of the suction nozzle with respect to the contact roller can be easily adjusted. Conventionally, there is known a technique of adjusting the positions of the package and the nozzle when the yarn catching section is positioned to catch the yarn, and in addition, the position of the nozzle with respect to the contact roller is adjusted, whereby the position of the nozzle can be determined more accurately.

In the textile machine, the position adjustment mechanism preferably moves a rotation center of the main body in the vertical direction.

This enables the height of the entire revolving rail of the yarn catching section to be adjusted.

In the above-described textile machine, the position adjusting mechanism is preferably integrally moved with the yarn drawing device.

This makes it possible to intensively process the yarn pulling device and the position adjusting mechanism at the time of manufacture. Thus, the manufacturing man-hour can be reduced.

In the textile machine, the position adjustment mechanism preferably includes a lever member that moves a rotation center of the main body.

This enables the position of the rotation center of the main body to be adjusted with a simple configuration.

In the textile machine, it is preferable that a hole for attaching the lever member is formed in the yarn pulling-out device.

This makes it possible to easily attach the lever member to the yarn pulling device.

In the above-described textile machine, the following structure is preferable. That is, the lever member is formed to be elongated and supported rotatably. A fastening member is disposed at a rotation center portion of the lever member. By tightening the tightening member, the angle of the lever member can be maintained.

Thus, the rotation center of the main body can be fixed so as not to move, if necessary.

In the above-described textile machine, the following structure is preferable. That is, the position adjustment mechanism includes a lever posture adjustment member that changes the posture of the lever member. The lever posture adjusting member can be attached to the lever member without a fastening member.

This allows the lever posture adjustment member to be easily removed. For example, by sharing the lever posture adjustment member in a plurality of textile machines, the cost of the parts can be reduced.

In the above-described textile machine, the following structure is preferable. That is, the lever member is formed to be elongated and supported rotatably. A holding mechanism for holding the angle of the lever member is provided at a position different from the rotation center portion of the lever member.

Thus, the rotation center of the main body can be fixed so as not to move by a simple configuration.

In the textile machine, it is preferable that a tool for confirming the position of the yarn catching portion whose position is changed with the movement of the rotation center of the main body portion is attached to the yarn catching portion at a yarn catching position.

Thus, the position of the yarn catching portion with respect to the contact roller can be easily checked.

In the textile machine, the tool preferably has a scale.

This allows the position of the yarn catching portion to be checked more accurately.

Next, the structure of the winding unit 4 will be described in more detail with reference to fig. 2. Fig. 2 is a side view schematically showing an example of the structure of the winding unit 4 of the automatic winder 1.

As shown in fig. 2, the winding unit 4 includes a yarn winding section 5 and a yarn processing section 10. The yarn winding section 5 is arranged at the upper portion of the main frame 2 in the vertical direction. The yarn processing section 10 is arranged below the yarn winding section 5 in the vertical direction. The yarn processing section 10 includes a yarn feeding replacement section 3 and a joint section 8. The yarn feeding and replacing unit 3 is disposed below the yarn processing unit 10. The joint portion 8 is disposed between the yarn winding portion 5 and the yarn feeding replacement portion 3.

The winding unit 4 is a module-divided unit, and is configured by combining 3 modules of the yarn feeding replacement section 3, the joint section 8, and the yarn winding section 5, which are arranged in this order from below. Each device attached to the yarn feeding replacement section 3, the joint section 8, and the yarn winding section 5 is provided as a module so as to be detachable from the main frame 2.

The yarn feeding and replacing unit 3 is a part of the yarn processing unit 10. The yarn feeding replacement portion 3 is a portion in which a yarn feeding bobbin 6 (or a yarn feeding package) for winding yarn onto the package 9 is provided so as to be replaceable. The yarn feeding replacement section 3 is mounted on the lower portion of the main frame 2 so as to be placed on the bottom plate section 12 of the main frame 2.

The yarn feeding and replacing unit 3 is configured by selectively attaching any one of a plurality of types of yarn feeding and replacing devices. Specifically, any one of a magazine type bobbin feeding device, a tray type bobbin feeding device 30, and a package feeding device can be mounted to the yarn feeding and replacing unit 3 of the present embodiment.

The joint portion 8 is a part of the yarn processing portion 10. The joint portion 8 is a portion for joining the yarn supplied from the yarn supplying and changing portion 3 to the yarn winding portion 5. The joint portion 8 is attached to the middle portion of the main frame 2 in the up-down direction. Specifically, the joint portion 8 is mounted on the main frame 2 at a position above the position where the yarn replacement portion 3 is provided and at a position below the position where the yarn winding portion 5 is mounted. The joint portion 8 is mounted on the front surface side of the main frame 2, for example, by a suitable fixing member (e.g., a bolt). In a state where the joint portion 8 is fixed to the main frame 2, the weight of the joint portion 8 is supported by a support shaft 14 provided in the main frame 2.

The winding unit 4 configured using an example of the combination of the above 3 modules will be described in detail below.

The winding unit 4 shown in fig. 2 is configured such that an arm-traversing yarn winding device (yarn winding mechanism) 60 is mounted on the yarn winding section 5, a conveying tray type bobbin supplying device 30 is mounted on the yarn feeding replacement section 3, and a suction nozzle type yarn splicing mechanism 70 is mounted on the yarn splicing section 8.

The yarn winding device 60 includes a winding tube 61, a winding tube rotation driving source, not shown, a cradle 62, a contact roller 63, a yarn winding frame 64, a traverse arm 67, and a traverse driving motor 66.

The cradle 62 rotatably supports the winding tube 61. The winding tube 61 is coupled to an output shaft of a winding tube rotation driving source and is driven to rotate. The traverse arm 67 is reciprocally driven by the traverse driving motor 66.

The contact roller 63 is rotatably supported by the yarn winding frame 64. One axial end of the contact roller 63 is attached to the yarn winding frame 64. The contact roller 63 is rotatable in contact with the circumferential surface of the winding tube 61. The contact roller 63 may be rotatably attached to a support arm, not shown, or the like fixed to the yarn winding frame 64, for example.

Various devices of the yarn winding device 60 are disposed on one side of the yarn winding frame 64 in the lateral direction. The various devices include a cradle 62, a take-up tube rotation drive source, a traverse drive motor 66, and the like. The traverse arm 67 is reciprocally driven by the traverse driving motor 66.

The traverse arm 67 reciprocates by repeatedly rotating the rotor of the traverse drive motor 66 in the forward and reverse directions. Thereby, the yarn caught by the tip end of the traverse arm 67 is supplied to the contact roller 63 side while traversing, and is wound around the rotating winding tube 61. Thereby, the package 9 of the yarn of the winding yarn feeding bobbin 6 can be formed.

The bobbin supply device 30 includes a bobbin installation section 31, a yarn unwinding assisting device 39, and a support body 38.

The bobbin setting section 31 can hold the yarn feeding bobbin 6 for unwinding the yarn at a predetermined position in an upright posture. The yarn unwinding assisting device 39 brings the movable member into contact with a balloon formed on the upper portion of the yarn feeding bobbin 6, and appropriately controls the size of the balloon to assist in unwinding the yarn. The support 38 supports the yarn unwinding assisting device 39 at a position above the bobbin installation section 31. The bobbin installation section 31 (and thus the conveying tray type bobbin supply device 30) is attached to the main frame 2 in a state where the bottom of the bobbin installation section 31 is placed on the bottom plate section 12.

The suction nozzle type yarn joining mechanism 70 includes a yarn monitoring device 71, a splicer 72, a 1 st yarn capturing device 73, a 2 nd yarn capturing device (yarn drawing device) 74, a tension applying device 75, and a joining frame 76.

The joint frame 76 is a longitudinally elongated substantially rectangular parallelepiped member. The yarn monitoring device 71, the splicer 72, the 1 st yarn capturing device 73, the 2 nd yarn capturing device 74, and the tension applying device 75 are disposed on the left and right sides of the splice frame 76. The joint frame 76 cantilevers these components.

The joint frame 76 is attached to the middle portion in the vertical direction of the main frame 2 in a state of supporting the above-described portions. The tab frame 76 and the yarn winding frame 64 are aligned in the left-right direction to separate the tab portions 8 of the adjacent winding units 4 from each other. The yarn winding frame 64 and the tab frame 76 are not directly connected, and a gap is formed as a space between them (in the up-down direction).

A unit controller 90 and the like are disposed inside the joint frame 76. The unit controller 90 functions as a control unit for controlling each unit of the winding unit 4.

The yarn monitoring device 71 monitors the thickness of the yarn to detect defects (hereinafter, sometimes referred to as yarn defects) such as a slub yarn generated in the yarn. A cutter for cutting the yarn immediately when the yarn monitoring device 71 detects a yarn defect is disposed in the vicinity of the yarn monitoring device 71.

When the yarn monitoring device 71 detects a yarn defect and cuts the yarn by a cutter, when the yarn is cut off from the yarn unwound from the yarn feeding bobbin 6, when the yarn feeding bobbin 6 is replaced, or the like, the splicer 72 joins the yarn on the yarn feeding replacing section 3 side and the yarn on the yarn winding section 5 side. In the splicer 72 of the present embodiment, the yarn is spliced by supplying compressed air from a compressor, not shown, to twist the yarn.

The 1 st yarn catching device 73 and the 2 nd yarn catching device 74 are provided on the lower side and the upper side of the splicer 72. The 1 st yarn catching device 73 attracts, catches and guides the yarn on the yarn feeding replacement portion 3 side. The 2 nd yarn catching device 74 attracts and catches and guides the yarn on the side of the yarn winding section 5. A suction port is formed at the tip of the 1 st yarn catching device 73, and a suction nozzle (yarn catching portion) 74b is provided at the tip of the 2 nd yarn catching device 74. The 1 st yarn catching device 73 and the 2 nd yarn catching device 74 are connected to the opening 13a of the blower duct 13 via a pipe or the like. This can generate suction flow at the suction port and the suction nozzle 74b.

In this configuration, when the yarn feeding bobbin 6 is replaced or the like, the suction port of the 1 st yarn catching device 73 is rotated downward to catch the yarn on the yarn feeding replacement portion 3 side, and then the yarn is guided to the splicer 72 by being rotated upward. At substantially the same time, the suction nozzle 74b of the 2 nd yarn catching device 74 catches the yarn unwound from the package 9 driven in reverse, and then, the yarn is guided to the splicer 72 by being rotated downward. Then, the splicer 72 splices the yarn supplied from the yarn replacement section 3 and the yarn supplied from the package 9.

Hereinafter, the position of the suction nozzle 74b when the suction nozzle 74b applies the suction flow to the surface of the package 9 in the 2 nd yarn capturing device 74 may be referred to as a "capturing position" of the suction nozzle 74b. In order to improve the yarn catching success rate by making the suction flow act well on the surface of the package 9, it is important to make the positional relationship of the suction nozzle 74b with respect to the package 9 accurate.

Next, the structure of the 2 nd yarn catching device 74 in the winding unit 4 according to the present embodiment will be described in detail. Fig. 3 is a perspective view showing the structure of the 2 nd yarn catching device 74. Fig. 4 is an exploded perspective view showing the installation of the 2 nd yarn catching device 74.

The 2 nd yarn catching device 74 includes a catching tube (main body portion) 74a, a suction nozzle 74b, a driving motor 74c, and a housing 74d.

The catching pipe 74a is supported by the housing 74d so as to be rotatable up and down. A suction nozzle 74b is attached to an end of the catch pipe 74a on a side away from the center of rotation. In the following description, the side of the capturing tube 74a where the suction nozzle 74b is disposed is referred to as the "tip side", and the side near the center of rotation is referred to as the "root side".

The suction nozzle 74b can rotate from the standby position shown by the solid line in fig. 2 to the capturing position shown by the broken line in fig. 2 with the rotational movement of the capturing tube 74a. That is, the suction nozzle 74b rotates around the root side of the catching pipe 74a. The catching tube 74a is formed of a member having rigidity. Thus, the distance from the root-side end portion (further, the rotation center C1) of the capturing tube 74a to the suction nozzle 74b is constant regardless of the posture of the capturing tube 74a.

The trap tube 74a is connected to the opening 13a of the blower pipe 13 via a pipe or the like not shown. The catching tube 74a forms a path through which a suction flow for sucking the yarn flows. This can apply suction flow to the opening of the suction nozzle 74b.

The drive motor 74c supplies power for rotating the catching pipe 74a. The drive motor 74c is fixed to the housing 74d at a position lower than the root of the catching pipe 74a. The position where the drive motor 74c is mounted is not particularly limited.

The case 74d is formed in a thin cover shape. The case 74d may be formed as a metal stamping, for example, and the material of the case 74d is not limited. For example, it can be formed of a synthetic resin. As shown in fig. 3, a catch tube 74a is rotatably attached to one surface of the case 74d in the thickness direction.

The housing 74d is mounted to the left and right sides of the joint frame 76 via appropriate fastening members (e.g., bolts 92, screws, etc.). Thereby, a storage space is formed between the housing 74d and the joint frame 76. Although not shown, a gear for rotating the catching tube 74a, a belt for transmitting power from the drive motor 74c to the gear, and the like are disposed in the housing space.

As shown in fig. 4, a positioning hole 74e and a plurality of 1 st mounting holes 74f are formed in the case 74d. The positioning hole 74e and the 1 st mounting hole 74f are used to mount the housing 74d (i.e., the 2 nd yarn catching device 74) to the joint frame 76. The housing 74d is formed with a through hole 74g and a rod hole 74k. A reference pin 95 described later is inserted into the through hole 74 g. A transmission lever 94 described later is mounted in the lever hole 74k.

In contrast, in the winding unit 4 of the present embodiment, the positioning pin 76a, the reference pin hole 76b, and the plurality of 2 nd attachment holes 76c are formed in the tab frame 76. The plurality of 2 nd mounting holes 76c are preferably formed at a plurality of positions in the front-rear direction and the up-down direction (i.e., the vertical direction) as shown in fig. 4.

The positioning pin 76a and the 2 nd mounting hole 76c are used to mount the 2 nd yarn catching device 74 to the joint frame 76. The reference pin hole 76b is used to change the position of the center of rotation of the catcher tube 74a by changing the posture of the housing 74d.

The positioning hole 74e is a hole provided in the housing 74d, and the positioning pin 76a is a columnar pin. The inner diameter of the positioning hole 74e is substantially equal to the outer diameter of the positioning pin 76 a. When the 2 nd yarn catching device 74 is attached to the joint frame 76, the positioning pin 76a is inserted into the positioning hole 74e of the housing 74d. The positioning pin 76a is a central axis when the posture of the housing 74d is changed with respect to the joint frame 76.

The 1 st mounting hole 74f is formed at a position corresponding to the 2 nd mounting hole 76c. The 1 st mounting hole 74f is formed slightly larger than the thickness of the shaft portion of the bolt 92. Thereby allowing a degree of positional adjustment of the housing 74d relative to the joint frame 76. The 1 st mounting hole 74f may be formed as a long hole or a round hole as long as it is larger than a circle corresponding to the shaft portion of the bolt 92.

By inserting the positioning pin 76a into the positioning hole 74e, the housing 74d of the 2 nd yarn catching device 74 is rotatably supported with respect to the joint frame 76. In other words, the positioning pin 76a functions as a reference point for fixing the housing 74d. In a state where the housing 74d is rotated to an appropriate position about the positioning pin 76a, the bolt 92 or the like is inserted into the 1 st mounting hole 74f and fastened to the 2 nd mounting hole 76c. Thus, the 2 nd yarn catching device 74 is mounted to the joint frame 76.

The passing hole 74g is formed as a long hole. In the present embodiment, the path through which the hole 74g rotates relative to the reference pin 95 about the fulcrum bolt 92a is formed sufficiently large.

Next, the position adjusting mechanism 93 for adjusting the position of the 2 nd yarn capturing device 74 (and further, the position of the rotation center C1 of the capturing tube 74 a) will be described in detail with reference to fig. 4 and 5. Fig. 5 is an enlarged view showing a part of the configuration of the position adjustment mechanism 93.

As shown in fig. 4, the position adjustment mechanism 93 includes a transmission lever (lever member) 94, a reference pin 95, and an operation lever (lever posture adjustment member) 96. As shown in fig. 4, the transmission lever 94 and the operation lever 96 are provided on the surface opposite to the joint frame 76 in the thickness direction of the housing 74d (the left-right direction of the joint frame 76). The surface of the housing 74d to which the transmission lever 94 and the operation lever 96 are attached may be referred to as a surface on the side from which the root portion of the trap tube 74a protrudes from the housing 74d.

The transfer lever 94 is formed in an elongated plate shape. A reference pin 95 is fixed to one end side of the transmission lever 94 in the longitudinal direction. A protrusion is formed on the opposite side of the reference pin 95 in the longitudinal direction of the transmission lever 94. The operation lever 96 is attached to the projection. In the following description, a side close to the reference pin 95 in the longitudinal direction of the transmission lever 94 is referred to as a "reference pin side", and a side to which the operation lever 96 is attached is referred to as an "operation receiving side".

The transmission lever 94 is attached to the housing 74d at its longitudinal center portion via a fulcrum bolt 92a. The fulcrum bolt 92a is fixed to a lever hole 74k formed in the housing 74d. Thus, the transmission lever 94 is rotatably supported by the housing 74d about the axis of the fulcrum bolt 92a.

The fulcrum bolt 92a couples the transmission lever 94 to the housing 74d, but is independent of the coupling between the housing 74d and the joint frame 76. The fulcrum bolt 92a is screwed to the housing 74d, and is fastened to maintain an angle so as not to rotate the transmission lever 94.

As shown in fig. 4 and 5, the fulcrum bolt 92a is located rearward of the root-side end of the catch pipe 74a in the front-rear direction of the winding unit 4 (the joint frame 76). The pivot bolt 92a is the center of rotation, and the reference pin side is located at the rear lower side and the operation receiving side is located at the front upper side.

The reference pin 95 is a round bar-shaped member. The reference pin 95 protrudes from the transmission rod 94 toward the joint frame 76 in the thickness direction of the transmission rod 94 (the left-right direction of the joint frame 76). The reference pin 95 is inserted into a reference pin hole 76b formed in the joint frame 76 through a passing hole 74g formed in the housing 74d.

Thus, when the transmission lever 94 rotates about the axis of the fulcrum bolt 92a, the reference pin 95 moves relatively along an arc-shaped track about the axis of the fulcrum bolt 92a. The radius of the arc is equal to the distance between the axis of the fulcrum bolt 92a and the axis of the reference pin 95. The passing hole 74g has a sufficient play with respect to the reference pin 95, and therefore, even if the reference pin 95 moves along the rail, the reference pin 95 does not come into contact with the passing hole 74 g.

When the 2 nd yarn catching device 74 is attached to the joint frame 76, the reference pin 95 is inserted into the reference pin hole 76b formed in the joint frame 76. The reference pin hole 76b is formed as a hole elongated in the front-rear direction. The dimension of the reference pin hole 76b in the up-down direction is substantially equal to the outer diameter of the reference pin 95.

The height of the reference pin 95 is restricted from changing by the reference pin hole 76 b. Accordingly, when the reference pin 95 is raised relative to the fulcrum bolt 92a with the rotation of the transmission lever 94, the fulcrum bolt 92a is pressed down relative to the reference pin hole 76 b. When the reference pin 95 is lowered relative to the fulcrum bolt 92a with rotation of the transmission lever 94, the fulcrum bolt 92a is pushed up relative to the reference pin hole 76 b. Thus, the housing 74d can be rotated about the positioning pin 76a to change its posture.

The lever 96 is formed in a plate shape elongated in the substantially front-rear direction. The lever 96 is disposed so as to pass above the root-side end of the catching pipe 74a. The operation lever 96 is disposed on a surface of the case 74d on the side where the transmission lever 94 is mounted. The lever 96 is disposed along a face of the housing 74d. The lever 96 of the present embodiment has an arc-shaped portion that turns upward with respect to the root-side end portion of the catcher tube 74a. However, the shape of the lever 96 is not limited.

As shown in fig. 4 and the like, the operation lever 96 is provided to extend in the front-rear direction of the joint frame 76 (i.e., the housing 74 d).

One end side (rear end side shown in fig. 4) of the operation lever 96 in the longitudinal direction is formed in a U shape when viewed from the thickness direction. The operation receiving side of the transmission lever 94 is fitted into the recess of the U-shaped portion. In a state where the operation lever 96 is attached to the transmission lever 94, the angle of the transmission lever 94 is also integrally changed with the change in the angle of the operation lever 96. In the following description, a side that is connected to the transmission lever 94 in the longitudinal direction of the operation lever 96 is referred to as a "connection side".

A fixing pin 96a shown in fig. 4 is provided at an end portion of the operation lever 96 on a side (front side shown in fig. 4) away from the transmission lever 94 in the longitudinal direction. In the following description, this side of the operation lever 96 will be referred to as "operation side". The operator can change the angle of the lever 96 by pushing the operation side of the lever 96 in the up-down direction by hand.

A plurality of fixing pin holes 74h are formed in the housing 74d corresponding to the fixing pins 96a of the operation lever 96. As shown in fig. 4 and the like, the fixing pin holes 74h are formed in an aligned manner in the vertical direction on the front end side of the housing 74d. The fixing pin 96a can be inserted into 1 fixing pin hole 74h selected from a plurality. Thereby, the operation side of the operation lever 96 can be held at different positions in the up-down direction.

In this way, the connecting side of the operation lever 96 is fitted to the operation receiving side of the transmission lever 94, and the operation side is held by the fixing pin 96a inserted into the fixing pin hole 74h. The coupling side of the operation lever 96 is detachable from the transmission lever 94, and the operation side is detachable from the housing 74d. That is, the operation lever 96 can be easily detached from the case 74d.

As described above, the housing 74d can rotate around the positioning pin 76 a. The posture of the operation lever 96 mounted on the transmission lever 94 corresponds to the posture of the housing 74d one by one. Thus, by using the positioning pin 76a and the fixing pin hole 74h, the posture of the housing 74d can be maintained at a plurality of different positions.

The transmission rod 94 and the fulcrum bolt 92a, which constitute the position adjusting mechanism 93, are attached to the housing 74d. Accordingly, when the 2 nd yarn capturing device 74 moves in the vertical direction by the position adjustment, the position adjustment mechanism 93 moves in the vertical direction as well. The position adjustment mechanism 93 can be integrally handled with the 2 nd yarn catching device 74 in a manner of being attached to the 2 nd yarn catching device 74. Thus, the man-hour for assembly can be reduced.

Next, the adjustment of the posture of the 2 nd yarn capturing device 74 (and further, the adjustment of the position of the rotation center C1 of the capturing tube 74 a) will be described in detail with reference to fig. 5, 6, and 7. Fig. 6 is a diagram showing a change in the position of the root-side end of the trap tube 74a. Fig. 7 is a perspective view showing a change in the relative position of the suction nozzle 74b and the contact roller 63.

In the present embodiment, the position of the rotation center C1 (root-side end portion) of the catching tube 74a is adjusted in a state where the 2 nd yarn catching device 74 is attached to the joint frame 76.

Specifically, the operator first attaches the operation lever 96 to the transmission lever 94. At this time, the position of the fixing pin 96a of the operation lever 96 is generally coincident with any one of the plurality of fixing pin holes 74h. The operator inserts the fixing pin 96a of the lever 96 into the fixing pin hole 74h having the same position.

Next, the operator loosens the fulcrum bolt 92a. Thereby, the transmission lever 94 is rotatable.

Next, the operator loosens a plurality of bolts 92 (3 in the present embodiment) for fixing the housing 74d to the joint frame 76. Even if the fixation of the housing 74d is lost, the position of the operation lever 96 is held by the fixing pin 96a and the fixing pin hole 74h, and therefore, the posture of the housing 74d is not changed by the self weight.

Thereafter, the operator moves only the operation side slightly away from the housing 74d while maintaining the state in which the operation lever 96 and the transmission lever 94 are coupled. Thereby, the connection between the fixing pin 96a and the fixing pin hole 74h is released. In this state, the operator changes the up-down position of the operation side of the operation lever 96.

As described above, when the operation lever 96 is pushed up, the fulcrum bolt 92a rises relatively to the reference pin hole 76 b. Thus, the housing 74d is pushed up to rotate about the positioning pin 76 a. As a result, the height of the root-side end portion of the trap tube 74a increases.

The left side of fig. 6 shows a state before push-up, and the right side shows a state after push-up. By raising the operation lever 96 from the lowermost fixing pin hole 74h to the uppermost fixing pin hole 74h, the rotation center C1 of the catching pipe 74a is raised by the distance L1. Strictly speaking, the rotation center C1 of the catching pipe 74a describes an arc of a circle centered on the positioning pin 76 a. However, in essence, the movement locus of the rotation center C1 of the trap tube 74a can be regarded as a straight line in the up-down direction.

When the lever 96 is depressed, the fulcrum bolt 92a is relatively lowered with respect to the reference pin hole 76 b. Thus, the housing 74d is pressed down to rotate about the positioning pin 76 a. As a result, the height of the root-side end portion of the trap tube 74a decreases.

The operation lever 96 and the transmission lever 94 function as levers with the fulcrum bolts 92a as fulcrums. Therefore, even if the lever 96 is moved greatly, the height of the 2 nd yarn capturing device 74 can be finely adjusted, and thus the operation is smooth.

After the catcher tube 74a is adjusted to a good height, the operator maintains the state in which the operation lever 96 is coupled to the transmission lever 94, and moves only the operation side slightly so as to approach the housing 74d. Thereby, the fixing pin 96a and the fixing pin hole 74h are coupled again at the changed lever angle. Even if the operator releases his/her hand from the housing 74d in this state, the posture of the housing 74d is not changed by the self weight.

In this state, the operator tightens the plurality of bolts 92 to fix the housing 74d to the joint frame 76. After that, after tightening the fulcrum bolt 92a, the operation lever 96 is detached from the transmission lever 94. The adjustment of the height of the 2 nd yarn catching device 74 is completed according to the above.

If the height of the root end of the capturing tube 74a is changed, the height of the capturing position of the suction nozzle 74b is also changed in association with this. The upward arrow in fig. 7 shows an example in which the capturing position of the suction nozzle 74b moves upward relative to the contact roller 63 (the rotation axis of the contact roller 63) as a result of the rising of the root-side end portion of the capturing tube 74a. If the root-side end of the catching pipe 74a descends, the catching position moves downward with respect to the contact roller 63. In fig. 7, the package 9 is removed from the cradle 62 for the adjustment operation, but the package 9 is not shown, but the adjustment may be performed in a state where the package 9 is attached to the cradle 62. In this way, the position adjustment mechanism 93 functions substantially as a height adjustment mechanism for the capturing position.

The capturing position of the suction nozzle 74b may be changed along an arc centered on the root-side end (rotation center C1) of the capturing tube 74a. This change is achieved by changing the setting of the angle at which the unit controller 90 controls the drive motor 74c to stop the rotation of the catch pipe 74a in a software manner. In the present embodiment, substantially, the vertical adjustment of the capturing position of the suction nozzle 74b is performed by the position adjustment mechanism 93, and the vertical adjustment is performed by the setting of software. This enables a highly flexible position adjustment operation.

In the present embodiment, the joint portion 8 constituting the 1 winding unit 4 and the yarn winding portion 5 are physically different modules, and are fixed to the main frame 2. Thus, there is a tendency that the relative positions of the yarn winding portion 5 and the joint portion 8 are different between the winding units 4. In this case, in the present embodiment, since the position of the rotation center C1 of the catch tube 74a can be adjusted in the height direction, the interval between the suction nozzle 74b and the contact roller 63 can be easily made uniform between the winding units 4. As a result, in the automatic winder 1 including the plurality of winding units 4, the efficiency of each winding unit 4 can be improved and the variation in production quality can be reduced.

As shown in fig. 7, the tool 68 for confirming the position of the suction nozzle 74b at the catch position can be mounted on the winding unit 4.

As shown in fig. 7 and 8, the tool 68 includes a base member 68a and a scale member 68b.

The base member 68a is formed in a horizontal plate shape. Two mounting pins 68e protruding downward are fixed to the bottom surface of the base member 68 a. The two mounting pins 68e are provided at intervals in the left-right direction shown in fig. 7.

A flat mounting surface for mounting a tool is formed on the upper surface of the yarn winding frame 64. Two mounting holes 64a are formed in the mounting surface corresponding to the two mounting pins 68e. The tool 68 is detachably attached to the upper portion of the yarn winding frame 64 by inserting the attaching pins 68e of the base member 68a into the two attaching holes 64a. The positioning of the tool 68 in the height direction is performed by the contact of the mounting surface with the bottom surface of the base member 68 a.

The scale member 68b is formed as a plate-like member. The scale member 68b is fixed to the front surface of the base member 68a by a bolt or the like, not shown. The scale member 68b has a portion extending from the base member 68a to one side in the horizontal direction.

The scale member 68b is provided so that its thickness direction coincides with the front-rear direction shown in fig. 7. Two kinds of graduations 68c and 68d are provided on one surface of the graduation member 68b in the thickness direction. Hereinafter, the surface marked with the scale of the scale member 68b may be referred to as a scale surface. When the suction nozzle 74b is located near the capturing position, the tip end portion of the suction nozzle 74b formed in a tapered shape faces the scale surface.

The scale 68c is formed of a plurality of grooves extending in the left-right direction shown in fig. 7 and 8. The plurality of grooves are formed in a vertically spaced apart arrangement.

The scale 68d is formed of a plurality of circular holes. The scale 68d is disposed above the scale 68 c. The plurality of holes constituting the graduations 68d are formed in a plurality of rows (2 rows in the present embodiment) at equal intervals in the vertical direction.

As shown in fig. 7, when the tool 68 is mounted to the yarn winding frame 64, a part of the scale member 68b approaches above the contact roller 63. The graduations 68c, 68d are marked on the portion of the graduation unit 68b located above the contact roller 63. The portion of the scale member 68b located above the contact roller 63 can be brought into contact with the suction nozzle 74b located at the capturing position or the suction nozzle 74b in the middle of the movement.

With this configuration, the relative position between the suction port of the suction nozzle 74b and the contact roller 63 can be easily and accurately checked.

As described above, the winding unit 4 of the present embodiment includes the yarn winding device 60, the 2 nd yarn capturing device 74, and the position adjusting mechanism 93. The yarn winding device 60 winds the yarn to form the package 9. The 2 nd yarn catch device 74 pulls the yarn from the package 9. The 2 nd yarn catching device 74 has a catching tube 74a and a suction nozzle 74b. The catching pipe 74a is formed to be elongated and provided rotatably with one end as a rotation center C1. The suction nozzle 74b is provided at an end of the catching pipe 74a on a side away from the rotation center C1. The winding unit 4 is provided with a position adjusting mechanism 93 for adjusting the position of the rotation center C1 of the catch pipe 74a.

Thereby, the position of the rotation center C1 of the capturing tube 74a (and thus the capturing position of the suction nozzle 74 b) can be adjusted to an appropriate position.

In the winding unit 4 of the present embodiment, the yarn winding device 60 includes a contact roller 63. The contact roller 63 rotates in contact with the package 9. The position adjustment mechanism 93 moves the position of the rotation center C1 of the catching tube 74a to adjust the distance between the suction nozzle 74b and the contact roller 63 when the suction nozzle 74b is positioned at the yarn catching position.

Thus, by adjusting the rotation center C1 of the catching pipe 74a, the position of the suction nozzle 74b with respect to the contact roller 63 can be easily adjusted.

In the winding unit 4 of the present embodiment, the position adjustment mechanism 93 moves the rotation center C1 of the catch pipe 74a in the up-down direction.

This enables the height of the entire rotation rail of the suction nozzle 74b to be adjusted.

In the winding unit 4 of the present embodiment, the position adjusting mechanism 93 moves integrally with the 2 nd yarn catching device 74.

This makes it possible to collectively process the 2 nd yarn capturing device 74 and the position adjusting mechanism 93 at the time of manufacturing. Thus, the manufacturing man-hour can be reduced.

In the winding unit 4 of the present embodiment, the position adjustment mechanism 93 includes a transmission lever 94 that moves the rotation center C1 of the catch pipe 74a.

This allows the position of the rotation center C1 of the trap tube 74a to be adjusted with a simple configuration.

In the winding unit 4 of the present embodiment, a lever hole 74k for attaching the transfer lever 94 is formed in the 2 nd yarn catching device 74.

Thereby, the transfer lever 94 can be easily attached to the 2 nd yarn catching device 74.

In the winding unit 4 of the present embodiment, the transmission lever 94 is formed to be elongated and rotatably supported. A fulcrum bolt 92a is disposed at the rotation center portion of the transmission lever 94. By tightening the fulcrum bolt 92a, the angle of the transmission lever 94 can be maintained.

Thus, the rotation center C1 of the trap tube 74a can be fixed so as not to move, if necessary.

In the winding unit 4 of the present embodiment, the position adjustment mechanism 93 includes an operation lever 96 for changing the posture of the transmission lever 94. The operation lever 96 is provided so as to be attachable to the transmission lever 94 without fastening members.

Thereby, the operation lever 96 can be easily detached. By sharing the operation lever 96 among the plurality of winding units 4, the cost of the parts can be reduced.

In the winding unit 4 of the present embodiment, the transmission lever 94 is formed to be elongated and rotatably supported. A holding mechanism composed of a fixing pin 96a and a fixing pin hole 74h for holding the angle of the transmission lever 94 (indirectly via the operation lever 96) is provided at a position different from the rotation center portion of the transmission lever 94.

This makes it possible to fix the rotation center C1 of the trap tube 74a so as not to move with a simple structure.

The winding unit 4 of the present embodiment can be provided with a tool 68 for confirming the position of the suction nozzle 74b.

Thereby, the position of the suction nozzle 74b with respect to the contact roller 63 can be easily confirmed.

In the winding unit 4 of the present embodiment, the tool 68 has graduations 68c and 68d.

This allows the position of the suction nozzle 74b to be checked more accurately.

The preferred embodiments of the present invention have been described above, but the above configuration can be modified as follows. The modification may be performed alone or in any combination of a plurality of modifications.

A traverse drum type yarn winding device may be mounted to the yarn winding section 5.

The yarn supply replacement unit 3 may be provided with a magazine type bobbin supplying device, a package supplying device, or the like, for example.

The joint portion 8 may be provided with a yarn accumulating type joint mechanism, for example, in addition to the suction nozzle type joint mechanism 70.

The winding unit 4 may also be configured as an air spinning unit or a rotor spinning unit.

The position adjustment mechanism 93 may adjust the rotation center C1 of the trap tube 74a in the obliquely upward and downward direction.

The position adjustment mechanism 93 may be provided on the side of the joint frame 76, for example, instead of being provided on the side of the 2 nd yarn catching device 74.

The position adjustment mechanism may be constituted by a feed mechanism having a screw shaft in the up-down direction, for example. In this case, the transmission lever 94 and the operation lever 96 can be omitted.

Instead of providing the lever hole 74k, a fulcrum shaft may be provided in the housing 74d so as to protrude, and the transmission lever 94 may be rotatably supported by the fulcrum shaft.

The operation lever 96 may be fixed to the transmission lever 94 via a fastening member such as a bolt. The operating lever 96 may be non-detachably fixed with respect to the transmission lever 94. The operation lever 96 may be integrally provided with respect to the transmission lever 94.

The transmission lever 94 may be mounted so as not to be fastened by the fulcrum bolt 92a. The holding mechanism of the lever 96, which is composed of the fixing pin 96a and the fixing pin hole 74h, may be omitted.

In the above embodiment, the reference pin 95 is disposed on the opposite side of the lever 96 with respect to the fulcrum bolt 92a. As a result, if the operation lever 96 is operated upward, the rotation center C1 of the trap tube 74a can be raised, and if the operation lever 96 is operated downward, the rotation center C1 of the trap tube 74a can be lowered, so that an intuitive adjustment operation can be realized. However, the reference pin 95 may be disposed on the same side as the operation lever 96 with respect to the fulcrum bolt 92a.

The scale of the tool 68 may be formed of only one of the groove-shaped scale 68c and the circular hole-shaped scale 68d.

The tool 68 may be attached to the yarn winding frame 64 so that a part of the scale member 68b is slid in the left-right direction and is brought above the contact roller 63.

Instead of the tool 68, a noncontact distance meter, for example, can be used to confirm the position of the suction nozzle 74b.

The yarn winding frame 64 of the yarn winding section 5 and the joint frame 76 of the joint section 8 may be directly fixed to each other.

The winding unit 4 is not limited to the module-divided type. The position adjustment mechanism 93 can be applied to, for example, a winding unit configured to fix the yarn winding device 60 and the 2 nd yarn catching device 74 to a common unit frame.

The textile machine is not limited to the winding unit 4 of the automatic winder 1. The position adjustment mechanism 93 can be applied to, for example, a spinning unit of a spinning machine.
