Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a turret type take-up winder that alternately winds a continuously supplied yarn with two bobbin holders.

[Conventional technology]

Two bobbin holders are rotatably protruded from a rotatable turret plate, and several bobbins are inserted into each of the bobbin holders. One of the two bobbin holders is positioned at a winding position. The other is arranged at the standby position, the yarn is wound on the bobbin located at the winding position, and the turret plate is rotated by 180 degrees each time the bobbin is fully wound,
The winding of the thread on the empty bobbin newly at the winding position is started. In this manner, a revolving type yarn winding machine in which a continuously supplied yarn is alternately wound by two bobbin holders is already known.

By the way, in the above-described spinning winder, the operation of the yarn when transferring the yarn from the full bobbin to the empty bobbin will be briefly described as follows. In other words, when the bobbin at the winding position becomes full, the turret plate rotates 180 degrees, switches the positions of the two bobbin holders, the full bobbin is at the standby position, and the empty bobbin is newly positioned at the winding position. You. But,
At the time when each bobbin is located at the new position, the supplied yarn is still connected to the full bobbin at the standby position. The transfer of the yarn from the bobbin to the empty bobbin is completed. That is, when the yarn is caught by the slit of the empty bobbin, the yarn connected to the full bobbin is cut by the tension of the yarn due to the rotation of the empty bobbin, and is newly wound around the empty bobbin.

However, in the above-described spinning winder, there are the following problems when transferring a yarn from a full bobbin to an empty bobbin.

That is, the first problem is to prevent the full bobbin from being interfered by a yarn transfer device or other members described later.
This means that the diameter of the full bobbin is limited to a small one. In other words, in transferring the yarn from the full bobbin to the empty bobbin, it is necessary that the yarn is securely engaged with the slit of the empty bobbin, and that the yarn does not come off the end face of the full bobbin. The yarn must be within the winding width range of the full bobbin and travel along a path parallel to the slit of the empty bobbin. Therefore,
Conventionally, a yarn transfer device that bends a yarn between an empty bobbin and a full bobbin has been devised. However, in the above-described yarn winding machine, in most cases, the yarn transfer device is fixed to a turret plate or the like, and its position is invariable.
When the yarn is wound on the bobbin in each bobbin holder and the diameter of the yarn layer increases, the yarn transfer guide becomes an obstacle, and the diameter of the package when the winding of the yarn is completed is limited to a small one.

A second problem is that even when the full bobbin is in the standby position, the bobbin is initially rotated by affection, and the cut end of the full bobbin hits the patter and the empty bobbin due to the emotional rotation. For this purpose, the cut yarn end of the full bobbin is wound into the empty bobbin to prevent winding of the empty bobbin, or the yarn of the full bobbin that has been wound is unwound.

Therefore, as a conventional technique corresponding to the first problem, a spinning winder that secures a space by moving a cantilever-type yarn transfer device up and down between two bobbin holders by rotating operation or the like has been proposed. (See JP-A-60-153371). Also, as a conventional technology corresponding to the second problem,
It is known to provide a pivotable pivoting separator that covers the side of a full bobbin.

[Problems to be solved by the invention]

The prior art corresponding to the first problem is that the yarn transfer device is still located between the two bobbin holders,
The thickness of the full bobbin cannot be increased with respect to the thickness of the bobbin, and since it is cantilevered, chatter vibration is transmitted to the yarn transfer device. The conventional technology corresponding to the second problem has a problem in that the swirl separator can only cover the yarn transfer device up to the yarn transfer device position, and the cut yarn end may be wound around the empty bobbin beyond the yarn transfer device. Was.

By the way, as a countermeasure to these first and second problems, a device in which a full bobbin is covered with a pair of separators and a yarn guide for thread transfer is provided at the end of the separator has been proposed. In addition, since the arrangement of the thread guide is not appropriate, there is a problem that it is obstructive during normal winding.

The present invention has been made in view of such problems of the prior art, and has as its object to effectively utilize the space between two bobbin holders in a turret type take-up winder. In addition, the yarn transfer device is arranged so as not to interfere with normal winding, and the yarn transfer device can be accurately set to the operation position via an appropriate path when transferring the yarn from the full bobbin to the empty bobbin. An object of the present invention is to provide a spinning winder.

The elevating box (1) supports a touch roller (3), a traverse device (4), and a yarn pulling guide (5). The touch roller (3) is a bobbin (B) at a winding position described later. 1), and the bobbin (B) is driven to rotate counterclockwise in FIG.
The traverse device (4) is provided with a traverse guide (6). The traverse guide (6) engages with the yarn (Y) and travels in the traverse range to traverse the yarn (Y). ing. Further, upstream of the traverse device (4), when the positions of the full bobbin (B) and the empty bobbin (B) are switched and the yarn is transferred, the engagement between the yarn (Y) and the traverse guide (6) is released. And a yarn pulling guide (5) for moving the yarn (Y) out of the traverse range. As shown in FIG. 2, the yarn pulling guide (5) is provided on a plate (9) which slides along a guide rod (8) (a number corresponding to the number of bobbins, 2 in the figure).
The plate (9) is fixed to a piston rod (12) of a cylinder (11), and the operation of the cylinder (11) causes the yarn pulling guide (5) to move to the position shown in FIG.
Move to the dotted line position (13).

The turret plate (2) is rotatable around a rotation shaft (14) by a rotation drive device (not shown), and two bobbin holders (15) and (16) are rotatably projecting from the turret plate (2). The bobbin holder (1
5) On (16), several bobbins (B) each having a slit (17) formed at one end are respectively inserted (two in the figure), and one bobbin holder (15) is placed at the winding position (a). Meanwhile, the other bobbin holder (16) is located at the standby position (b). The turret plate (2) is the bobbin (B) at the winding position (a).
When the yarn (Y) is fully wound, it rotates 180 degrees, and switches the positions of the bobbin holders (15) and (16) so that the empty bobbin (B) newly located at the winding position (a) Then, the yarn (Y) from the full bobbin (B) is transferred, and the winding is continued. FIGS. 1 and 2 show a state in which the yarn (Y) is transferred, so that the full bobbin (B) is supported by the bobbin holder (17) at the standby position (b). ing.

The fixed frame (18) protrudes from the main frame (7) at a position not in the way of raising and lowering the lifting box (1), that is, at a position diagonally above the turret plate (2) and parallel to the lifting box (1). ing. An operation box (10) is provided at the tip of the fixed frame (18), and the inside of the fixed frame (18) is hollow except for a portion through which wiring passes. A slide arm (30) described later is provided in this cavity.

Next, the structures of the yarn transfer device, the slide arm, and the revolving separator, which are main parts of the present invention, will be described. The thread transfer device (20) has a structure in which a slide guide (21) and a fixed guide (22) are arranged vertically. As shown in FIG. 4, the slide guide (21) has a number of claws (23) corresponding to the number of bobbins (B), and can be slid to the position indicated by the two-dot chain line by the elongated hole (24). Normally, it is at the right position by the spring (25), but at the time of the operation shown in FIG. 2, it is pushed by the cylinder (26) provided on the turret plate (2) side to the left position, and the upstream position The yarn (Y) is captured by the slit (17) in cooperation with the yarn pulling guide (5) to perform rewinding and cutting. As shown in FIG. 4, the fixed guide (22) has a claw (27) facing the claw (23). In the operating position shown in FIG. 4, the thread (Y) is discharged from the full bobbin (B). The yarn path is regulated so that it does not fall off. in this way,
The slide guide (21) and the fixed guide (22) of the yarn transfer device (20) are arranged so that the yarn (Y) is captured by the slit (17) so that the yarn path to the full bobbin (B) does not shift. It works. The yarn transfer device (20) is provided by the cylinder (26) provided on the turret plate (2).
It is not necessary to have a driving portion, and the width of the slide arm (30) described below can be narrowed to reduce the overall weight.

Next, the slide arm (30) to which the thread transfer device (20) is attached will be described. As shown in FIG. 1, the slide arm (30) can advance from the storage position in the fixed frame (18) indicated by the two-dot chain line to the operating position indicated by the solid line by its vertical movement and swinging. When the yarn is transferred from the full bobbin (B) to the empty bobbin (B), the slide arm (30)
The bobbin holder (15) (16) is the thread transfer device (20) at the tip
Between the empty bobbin (B) and the full bobbin (B). The mechanism for vertically moving and swinging the slide arm (30) will be described with reference to FIG. The slide arm (30) has a partition plate (31) stretched around the outer surface of the frame structure, and has a single plate shape. A thread transfer device (20) is attached to the tip of this plate,
The terminal end is a bent portion (30a). This bend (30a)
, A fixed first shaft (32) and a rotatable second shaft (33) are inserted therethrough. The first roller followers (34) and (34) are fitted to both ends of the first shaft (32). Also, the second
A second roller follower (35) (35) and a pinion (36) (36) are fitted into both ends of the shaft (33), and a tip fitting (37a) of a fluid cylinder (37) is fixed to one end of the body frame side. I have. And both ends of the fixed frame are guide plates (38)
(38) and the first roller follower (34) (3
4) a first linear guide groove (39) (39) for guiding
A second straight guide groove (44) (44) for guiding the second roller follower (35) (35) and a pinion (36) (3
Racks (45) and (45) that engage with 6) are provided.
The slide arm (30) having the above structure operates as follows. When the fluid cylinder (37) in the extended state starts to contract, the left and right racks (45) (45) and the pinions (36) (36) engage with each other via the second shaft (33), and the slide arm (3
0) left and right synchronous vertical movement is ensured. And the first
Slide arm (30) while roller follower (34) (34) is in straight part (39a) (39a) of first guide groove
Simply descends. However, the first roller followers (34) and (34) are bent at the bent portions (39b) and (39) of the first guide groove.
When entering b), the bending portion (30a) of the slide arm gradually rotates counterclockwise, so that the tip of the slide arm (30) eventually swings between the bobbin holders (15) and (16). This lowering and swinging causes the thread transfer guide (20) at the end of the slide arm (30) to move the bobbin holder (15) (16)
Advance into the middle. Conversely, when the fluid cylinder (37) is extended, the slide arm (30) is housed in the fixed frame by swinging and rising.

Next, the revolving separator (41) is arranged on the opposite side of the slide arm (30), and has a size to cover the entire width direction of the full bobbin and a half side surface (the right side in the first illustration),
It is pinned by a boss (42) below the main body frame (7) and can be turned freely. Normally, it is at the standby position indicated by the two-dot chain line, but at the operation position, the yarn transfer guide (2
0) and the tip of the revolving separator (41) face each other. In other words, the space between the two is closed to the extent that the yarn (Y) passes and does not hinder the yarn passing. Therefore, between the full bobbin (B) and the empty bobbin (B), the right side in FIG. 1 is completely partitioned by the revolving separator (41), and the left side in FIG. 1 is completely partitioned by the slide arm (30). . However, the partition between the full bobbin (B) and the empty bobbin (B) is only the revolving separator (41) or another plate is used in combination, and the slide arm (30) has a frame structure such as an angle. You can also.

Next, the operation of the spinning winder having the above-described structure will be described with reference to FIG.

FIG. 5 (a) shows the state immediately before the bobbin (B) becomes full.
Since there is nothing in the space "S" between the full bobbin (B) and the empty bobbin (B), the full bobbin (B) can be made larger than before. And when it becomes full bobbin (B),
The turret plate (2) rotates clockwise, and at the same time, the elevating box (1) also descends to the state shown in FIG. 5 (b). In this state, the touch roller (3) is pressed against the empty bobbin (B), but the thread (Y) is wound around the full bobbin (B) without passing through the empty bobbin (B). Next, before the yarn pulling guide (5) described with reference to FIG. 2 operates, the slide arm (30) descends and swings to set the yarn transfer guide (20) to the operating position, and the rotating separator (41) also. It becomes the operating position.
Then, after the state shown in FIG. 5 (c) is reached, the yarn shifting guide (5) and the yarn transfer guide (20) operate to operate the empty bobbin (B).
The transfer of the yarn (Y) to is performed. At this time, since the full bobbin (B) keeps rotating, the yarn end (43) is swung, but is separated from the empty bobbin (B) by the slide arm (30) and the revolving separator (41). . Then, after the full bobbin (B) stops rotating, the slide arm (30) returns to the storage position, the revolving separator (41) returns to the standby position, and the full bobbin (B) is taken out and the empty bobbin (B) is taken out. B) is inserted and the state shown in FIG. 5D is obtained. And
The thread (Y) is wound around the empty bobbin (B) in contact with the touch roller (3) and returns to the state of FIG. 5 (a). As shown, the slide arm (30) is in the fixed frame (18) and does not obstruct the bobbin (B) being wound.

In the above example, the guide groove (39) for the slide arm (30) is bent and the guide groove (44) is straight, but these may be reversed. The mounted roller follower engages with a guide groove of a predetermined shape formed in the guide plate (38),
Any device may be used as long as the yarn transfer device (20) at the yarn end at the tip of the arm (30) draws a curved path between the bobbin holders.

[Effects of the Invention] The invention of claim 1 has a structure in which a slide arm with a thread transfer device attached to the tip is housed in a hollow portion in a fixed frame, and the fixed frame is positioned diagonally above the turret plate. As a result, the slide arm does not interfere with the normal winding state. Further, when a yarn break occurs during normal winding, an effect is obtained that the broken yarn can be prevented from entanglement with the slide arm.

Further, since the slide arm is made to advance by engagement of the first and second rollers of the slide arm with the first and second guide grooves having a predetermined shape of the fixed frame, the slide arm interferes with an empty bobbin or the like. There is also an effect that the advance mechanism of the slide arm, which allows the slide arm to advance from the upper storage position to the obliquely lower operation position, can be configured within the restricted space of the fixed frame.

Further, the engagement between the first and second rollers of the slide arm and the first and second guide grooves of the fixed frame can reduce play, thereby improving the advancement accuracy along the curved path of the slide arm. Thus, the yarn path of the yarn transfer device at the operating position can be regulated and the yarn can be shifted accurately.

And the above-mentioned effect can be achieved without increasing the machine width.

According to the invention of claim 2, since a partition plate is attached to such a slide arm and a separator is combined, the full bobbin and the empty bobbin can be completely separated from each other except for the yarn transfer device, and the empty bobbin of the full bobbin can be separated. This has the effect of completely preventing the yarn end from being caught in the thread.
