Description

TECHNICAL FIELD The present invention is applied to a sticking cloth as a final step when removing residual roving of a roving bobbin returned from a spinning machine to a roving machine. The present invention relates to a cleaning device for a residual roving removing device for a roving bobbin that can smoothly remove fiber scraps of the residual roving.

Conventional technology In a spinning factory, a roving bobbin that has been unwound with a roving in a spinning machine is completely removed from the roving remaining on the roving bobbin to make a complete empty bobbin, and then returned to the roving machine. To be reused. The roving bobbin returned from the spinning frame to the roving frame is a chain type between the spinning frame and the roving frame so that the roving bobbin can be continuously conveyed while being hung in a line on the bobbin hanger. Often, a transport line is built.

By the way, the roving bobbin removed from the spinning machine usually has residual roving remaining on its peripheral wall.Therefore, some residual roving remains on the roving bobbin being conveyed during the transfer line. It is convenient to install a residual roving yarn removing device to remove the yarn.

Therefore, in order to meet such technical requirements, the applicant has previously proposed a roving bobbin capable of efficiently removing the residual roving from the roving bobbin that is hung and conveyed by the bobbin hanger. A residual roving removing device has been proposed (Japanese Patent Laid-Open No. 62-
90337). This one pays attention to that the roving bobbin hung on the bobbin hanger is rotatable,
The roving bobbin is forcibly rotated by running the flocking belt in contact with the peripheral wall, and the residual roving on the roving bobbin is ejected by the flocking belt bristles, and the residual roving is unwound and removed. be able to.

Problems to be Solved by the Invention According to such a conventional technique, the residual roving yarn on the roving bobbin is unwound in order from the upper layer portion thereof, sequentially removed by a flocking belt, and then appropriately opened. However, there is a problem that it is difficult to completely remove the fiber waste adhering to the sticking cloth on the roving bobbin at the final stage. Here, the sticking cloth is a kind of narrow napped member adhered in a band shape on a part of the peripheral wall of the roving bobbin, and when winding the roving around the roving bobbin in the roving machine,
It is used for the purpose of fixing the winding start end and smoothing the start of the roving frame. Therefore, if the removal of the fiber waste on the sticking cloth is incomplete, the winding start end of the roving cannot be fixed, and the start of the roving machine becomes extremely difficult.

Therefore, in view of the circumstances of the conventional art, an object of the present invention is to rotate the roving bobbin in the forward and reverse directions, and blow air from the swinging air nozzle to the sticking cloth to remove the fiber waste on the sticking cloth. It is an object of the present invention to provide a cleaning device in a residual roving removing device for a roving bobbin that can be quickly and completely removed.

Means for Solving the Problems A structure of the present invention for achieving the above object is to provide a flocked belt which is in contact with a peripheral wall of a group of roving bobbins rotatably supported and which travels in forward and reverse directions, and a roving. And a rocking air nozzle for injecting air toward a sticking cloth attached to the peripheral wall of the bobbin in a strip shape.
The gist of the invention is to swing the air blowing direction in the width direction of the sticking cloth so as to cover the entire width of the sticking cloth.

Operation According to the structure of the invention, the flocked belt is
By traveling in contact with the peripheral wall of the roving bobbin having the residual roving, the roving bobbin can be rotated and the residual roving on the roving bobbin can be unwound and removed. In addition,
The rotation direction of the roving bobbin at this time may be the same as the winding direction of the residual roving. In this way, when the removal of residual roving other than the surface of the sticking cloth is completed, if air is jetted from the rocking air nozzle, the fiber waste adhering to the sticking cloth will become deeply entangled with the hair of the sticking cloth. Whatever was present, it can be floated up by the air, so that the fiber debris can then be blown into the air by the air or simply removed by the flocking belt.

At this time, if the traveling direction of the flocked belt is switched to the opposite direction, the action direction of the flocked belt with respect to the sticking cloth is reversed, and the roving bobbin can be rotated in a direction in which the fiber waste on the sticking cloth is loosened. Thus, the fiber debris can be pulled off the sticking cloth more easily. In addition, the oscillating air nozzle can oscillate the blowing direction of the air in the width direction of the sticking cloth to change the strength of the air acting on the surface of the sticking cloth. Even if it is entwined in a ring shape, it can be quickly opened and easily separated from the sticking cloth.

Example Hereinafter, an example will be described with reference to the drawings.

The cleaning device in the residual roving yarn removing device for the roving yarn bobbin is a flocking belt 1 that runs in contact with the roving yarn bobbins B, B.
1 and a swinging air nozzle 21 for injecting air toward the sticking cloth SC on the roving bobbin B (FIGS. 1 and 2), and a group of roving yarns being conveyed by the bobbin conveying device BC. The bobbins B, B ... Can be subjected to final cleaning for removing the fiber waste x on the sticking cloth SC.

The roving bobbins B, B ... Are mounted on the bobbin hangers BH, BH ...
It is rotatably suspended. A band-shaped sticking cloth SC is adhered to a part of the peripheral wall of each roving bobbin B in a squirrel-like manner, and this sticking cloth SC1 is laid in one direction on the surface of the base cloth SC1. Is a brushed member in which hair is planted on one surface (Fig. 3).

The flocked belt 11 is stretched between the pulleys 12 and 12,
An endless flat belt that runs along the bobbin transporting device BC (FIG. 2), and also has bristles 11a, 11a, etc. laid down in one direction on one surface thereof, and is fluffed as a whole as a whole. (Fig. 3). One of the pulleys 12 and 12 is a drive pulley connected to a drive motor (not shown), and this drive motor can switch the rotation direction between forward and reverse. Therefore, the flocked belt 11 moves forward and backward. It shall be able to drive. Further, the traveling position of the flocked belt 11 can be moved back and forth as needed so that an appropriate horizontal distance can be provided between the flocked belt 11 and the roving bobbins B, B.

The oscillating air nozzle 21 is assembled on a frame F that can be tilted downward via a rear shaft Fa (first).
Figure). However, the frame F can be retracted in a direction away from the roving bobbin B via a mechanism (not shown) so that the swinging air nozzle 21 does not interfere with the roving bobbins B, B when tilting downward. And

The rocking air nozzle 21 is provided with nozzle tips 21b, 21b, ... Corresponding to each of the roving bobbins B, B ... In the longitudinal direction of the air pipe 21a (FIGS. 1 and 2).
However, the air pipe 21a faces the group of roving bobbins B, B ...
Is arranged on the opposite side of the flocked belt 11 in parallel with.
The direction of each nozzle tip 21b is somewhat deviated from the center Bo of the corresponding roving bobbin B in the laying direction of the bristles SC2, SC2 ... Of the sticking cloth SC (Fig. 3). The air pipe 21a is rotatably supported via bearings 22 and 22 at two locations along the air hose 21a.
It is connected to a common air source (not shown) via c and 21c (FIGS. 1 and 2). However, the bearings 22, 22
Are fixed on the frame F via brackets BK1 and BK1.

A swing motor 23 with a speed reducer is assembled on the frame F via another bracket BK2, and an eccentric wheel 24 with a lever 24a is attached to a shaft end 23a thereof. On the other hand, the lever 25 is attached to the air pipe 21a.
A ring member 25 with a is attached, and the tips of the levers 24a and 25a are connected via a pin 26.

At the front end of the frame F, a group of roving bobbins B,
Corresponding to B ..., the rotating pegs PG, PG ... are projected, and each of the rotating pegs PG slips out below the roving bobbin B when the frame F is inclined (the two-dot chain line in FIG. 1). ), When the frame F is in the horizontal position (solid line in the figure), it can be inserted into the lower end portion of the roving bobbin B to prevent the swaying of the roving bobbin B.

A guide plate 27 bent in a wave shape is attached to the frame F at a height position corresponding to the lower ends of the roving bobbins B, B .... The guide plate 27 prevents the roving unwound from each roving bobbin B from extending to the adjacent roving bobbin B and wrapping around the corresponding rotating peg PG.

Now, the bobbin transfer device BC has its bobbin hanger BH,
When the roving bobbins B, B ... With residual roving are hung and operating on BH ..., a predetermined group of roving bobbins B, B. However,
At this time, the frame F is inclined downward, and
The flocked belt 11 is sufficiently retracted so as to be separated from the roving bobbins B, B .... Further, the bobbin transporting device BC is positioned and stopped so that the positions of the roving bobbins B, B, ... And the rotating pegs PG, PG ,.

Subsequently, when the frame F is set to the horizontal position, each rotating peg PG is inserted into the lower end of the corresponding roving bobbin B, and restrains the swinging of the lower part of the roving bobbin B. Therefore, the flocked belt 11 is moved forward so that the surface thereof is brought into contact with the residual roving yarns on the roving yarn bobbins B, B. At this time, the running direction of the flocked belt 11 is such that the roving bobbins B, B
... The tip of the residual roving above is the hair 1 on the surface of the flocked belt 11.
1a, 11a, ... are squeezed out and squeezed out, and it is determined that they are unwound. That is, in FIG. 3, assuming that the residual roving yarn is wound on the roving yarn bobbin B in the counterclockwise direction, the flocked belt 11 is caused to travel from the left to the right direction in FIG. May be rotated in the winding direction of the residual roving. The upper and lower ends of each roving bobbin B are rotatably supported by the bobbin hanger BH and the rotating peg PG. Therefore, the residual roving on the roving bobbin B is rotated by the roving bobbin B. It can be smoothly unwound and continuously removed by the flocking belt 11.

The residual roving thus removed may be peeled off from the flocked belt 11 and thrown away through a cotton collecting device (not shown).

In this way, the residual roving yarn on each roving yarn bobbin B is removed, and when the amount decreases, the flocked belt 11 is moved closer to the roving yarn bobbins B, B ... If the contact state with the belt 11 is maintained, all the remaining roving yarns on the roving yarn bobbin B are removed, and finally the flocked belt 11 directly contacts the peripheral wall of the roving yarn bobbins B, B .... (Fig. 1). At this time, the roving bobbin B,
In B ..., only a small amount of the fiber waste x adheres to each sticking cloth SC, and the residual roving yarn on the peripheral wall thereof does not remain. Further, when the roving is wound around the roving bobbin B in the roving machine in advance, these fiber wastes x are residues that are fixed at the winding start ends, and therefore, they can be peeled off by contact with the flocked belt 11. Hair of sticking cross SC2,
It digs deep into SC2 ... and adheres to it.

Therefore, air is blown from the rocking air nozzle 21 to the sticking cloth SC in this state. At the same time, if the swing motor 23 is started, the air pipe 21a
Is an eccentric wheel 24, levers 24a and 25a, a ring member 2
Inverse drive can be performed in the reverse direction through 5, and at this time,
The air blown from the nozzle tips 21b, 21b ... Can be swung up and down (solid line and chain double-dashed line in FIG. 1).

The air blowing direction A from the oscillating air nozzle 21 is slightly deviated from the center Bo of the roving bobbin B with respect to the horizontal direction (FIG. 3).
Fiber waste x that has penetrated deeply into C2, SC2 ...
Can be easily removed by peeling them off from the surface of the sticking cloth SC and blowing them away in the air, or by peeling them with the flocked belt 11. At this time, the air blowing direction A
The swing range of the eccentric wheel 24 and the lever 24a, 2
By appropriately determining the length of 5a, it is possible to cover the entire width of the sticking cloth SC. Therefore,
All the fiber waste x adhering to the surface of the sticking cloth SC can be quickly removed by the air from the rocking air nozzle 21.

In addition, here, the traveling direction of the flocked belt 11 is reversed, and the rotation directions of the roving bobbins B, B ... Are reversed, so that the bristles 11a, 11a of the flocked belt 11 and the bristles SC2 of the sticking cloth SC. It is possible to reverse the action directions based on the respective laying directions with SC2 (FIG. 3), and therefore it is also possible to separate the fiber waste x deeply entangled in the hairs SC2, SC2. .

In this way, when the removal of the residual rovings on the roving bobbins B, B ... And the fiber waste x on the sticking cloth SC is completed, the frame F is tilted to rotate the rotating pegs PG, PG.
... is removed downward, the flocked belt 11 is retracted, the operation of the bobbin transport device SC is restarted, the processed roving bobbins B, B ... are carried out, and the next group of roving bobbins are carried in. And can be done at the same time.

In the above description, since the rocking air nozzle 21 is supplied with air from both ends thereof, each nozzle tip 21
Air from b, 21b ... Has no fear that the blowing strength becomes extremely uneven. The mechanism for vertically swinging the air blowing direction A from the swinging air nozzle 21 may be an eccentric wheel 24, levers 24a, 25a, or any swinging mechanism such as a general crank mechanism. .

In addition, a group of roving bobbins B, B in contact with the flocking belt 11
, Instead of being rotatably hung on the bobbin hangers BH, BH, ..., Not only the lower end but also the upper end may be rotatably held by the rotating pegs PG, PG. Good. At this time, the frame F also has downwardly arranged rotating pegs PG, PG, ... Also, the roving bobbins B, B ... Are removed from the bobbin hangers BH, BH. A series of operating mechanisms for holding the rotating pegs PG, PG ... Since the bobbin hangers BH, BH ... Are not used when the roving bobbins B, B ... Are rotated, their durability is not impaired.

Further, the air pipe 21a of the rocking air nozzle 21 may be formed by simply arranging air injection holes in a row instead of projecting the nozzle tips 21b, 21b ...

EFFECTS OF THE INVENTION As described above, according to the present invention, a flocked belt that travels in forward and reverse directions in contact with a group of rotatably supported roving yarn bobbins and the entire width of the sticking cloth of the roving yarn bobbin By providing an oscillating air nozzle that blows air while oscillating the blowing direction, the fiber debris that deeply digs into the hair of the sticking cloth and adheres can be lifted by the air that is blown. By being blown into the air or peeled off by the flocking belt, it can be quickly and completely removed from the sticking cloth,
In the roving machine, there is an excellent effect that it is possible to eliminate the possibility of hindering the restart of winding the roving.

In addition, since the oscillating air nozzle oscillates the blowing direction of the air in the width direction of the sticking cloth, the air that acts on the fiber waste on the sticking cloth can be changed strongly, and the fiber waste can be made smoother. Moreover, even if the width of the sticking cloth is wide, the entire width of the sticking cloth can be covered and the sticking cloth can be easily dealt with.
