Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a creel for a spinning machine in which a preliminary roving bobbin is hung above and in front of a bobbin hanger row for spinning a spinning creel.

Prior Art Regarding the creel, for example, in JP-A-62-53425,
It is disclosed that the height of the bobbin hanger in the front row bobbin hanger row is substantially the same as the height of the lower end portion of the preliminary roving bobbin. This preliminary roving bobbin, when the spinning roving bobbin suspended in the front row spinning bobbin hanger row is close to the sky,
This spun roving bobbin is to be replaced and is prepared in advance along the front bobbin hanger row during spinning of the spinning machine.

Generally, spinning mills use traveling clearers that move along a spinning machine, and a blower traveling above the creel blows air downward to blow the cotton wool on the creel or machine base. Is falling. The air flow of the traveling clearer also acts on the outer circumference of the preliminary roving bobbin prepared for the spinning creel for replacement. The roving ends of some of the preliminary roving bobbins are peeled off by this air flow and hang down. The hanging roving thread ends are blown again by the air flow and adhere to the bobbin hangers of the front row bobbin hanger row, and the preliminary roving is rotated by the rotation of the spun roving bobbins suspended on this bobbin hanger. In some cases, the roving was pulled out from the bobbin and wound around the bobbin hanger in the spinning bobbin hanger row, resulting in poor rotation of the bobbin hanger. Such rotation failure is
There has been a problem that the smooth supply of the roving from the spun roving bobbin to the draft part is hindered, which leads to roving breakage and thin yarn generation. In addition, since the roving is drawn from the preliminary roving bobbin in this way, the preliminary roving bobbin is illegally consumed before being suspended on the bobbin hanger of the spinning bobbin hanger row, and the winding amount of the preliminary roving bobbin varies. When the spinning bobbin hanger was hung and was used for spinning, there was a risk that the roving was insufficient and the spinning operation could not be carried out smoothly. An object of the present invention is to provide a device for preventing the winding of the preliminary roving around the bobbin hanger of the bobbin hanger row for spinning, which solves the above problems.

Means for Solving the Problems In order to solve the problems, in a spinning creel in which a preliminary roving bobbin is hung above the front of the spun roving bobbin,
The spinning creel has a separate plate that separates the bobbin hanger of the front row spinning bobbin hanger row from the lower end of the spare roving bobbin at a height position corresponding to the rotating portion of the bobbin hanger row of the front row spinning bobbin hanger row. It is characterized in that it is provided separately from both and continuously over the longitudinal direction of the creel.

Action According to the above, even if the roving end of the preliminary roving bobbin is peeled off by the traveling clearer or the air flow due to the air conditioning in the factory and droops and is blown off, the attachment is prevented by the separate plate. The roving ends are prevented from getting caught in the bobbin hangers of the spinning bobbin hanger row.

Embodiments In FIGS. 1 and 3, a spinning creel 1 is provided with creel pillars 3 standing upright in the longitudinal direction at a center of a machine base 2. The spinning creels 1 are symmetrical, and only the left side is shown. Horizontal support brackets 4 project from the creel pillars 3 to the left and right. Suspending rods 5 each having a substantially bobbin length hang down from the horizontal support brackets 4, and a front row creel bar 6 is fixed along the longitudinal direction of the machine base 2 between the lower ends of these suspending rods 5 in the longitudinal direction. ing. A rear row creel bar 8 is fixed to the creel pillar 3 via a support bracket 7 along the longitudinal direction. L-shaped hanger brackets 9 are fixed to the front and rear row creel bars 6, 8 at a predetermined pitch P in the machine longitudinal direction, and bobbin hangers 10 are attached to the respective hanger brackets 9 for spinning. The bobbin hanger rows 11 and 12 are formed. The bobbin hanger 10 is a hanger bracket 9 as shown in FIG.
A cylinder 10c is rotatably mounted on a flange 10b at the tip of a hanging rod 10a, which is integrally connected to the cylinder 10.
It is a known umbrella type in which a hanger body 10d is integrally connected to a c by a pin 10e, and a hanging claw which is engaged with and disengaged from an inner portion of the roving thread bobbin B by the vertical movement of the roving thread bobbin B at the tip of the hanger body 13. (Not shown).

A spare rail 20 is fixed to the end of the horizontal support bracket 4 along the longitudinal direction of the machine base 2. This spare rail 20
Is a connection between the fine spinning machine and the rough spinning machine, and along this spare rail 20, a bobbin hanger row for spinning in the fine spinning creel 1
The same number of bobbin hangers 10 in the front row as the bobbin hangers 10 in the front row at the same pitch as the pitch P of 11 carriage carriages 21 that hang the same number of bobbin hangers 10 are adapted to travel. When the suspended preliminary roving bobbin FB faces the bobbin hangers 10 of the front row spinning bobbin hanger row 11, the bobbin hangers 10 hung on the carriage bar 21 form the preliminary roving bobbin hanger row 22. It Bobbin hanger row for this spare roving
The lower end portion (lower conical portion 23) of the preliminary roving bobbin FB suspended on each bobbin hanger 10 of 22 has substantially the same height as the hanger body 10d of the spinning bobbin hanger row 11 of the front row. The spare roving bobbin FB is used to replace the spun roving bobbin B in the front row when the spun roving bobbin B becomes a small ball or an empty bobbin.

The bobbin hangers 10 of the spinning bobbin hanger row 11 and the spares of the bobbin hanger row 22 for the spare roving are reserved at the height positions corresponding to the rotating parts (the hanger body 10d and the cylinder 10c) of the bobbin hangers 10 of the front spinning bobbin hanger row 11. A separate plate 24 bent in a V shape in the direction of the preliminary roving bobbin FB so as to partition the lower end 23 of the roving bobbin FB is provided on the side of the preliminary roving bobbin hanger row 22 of the front row creel bar 6. It is fastened together with the hanger bracket 9 (on the left side) by screws 25. The separate plate 24 has a length extending between the creel pillars 3 in the machine longitudinal direction, and the bent lower end of the separate plate 24 has a bobbin hanger row for spinning.
It is located at substantially the same height as the upper collar portion 26 of the spun roving bobbin B suspended from the bobbin hanger 10 of 11. Incidentally, 27 is
A roving bobbin exchanging machine that replaces the spun roving bobbin B in the rear row and moves the spun roving bobbin B that is empty or nearly empty to the front row.
28 is a traveling clearer, 29 is a roving guide, 30
Is a roller part and 31 is a spindle.

According to such a configuration, the full roving bobbins doffed from the roving machine (not shown) are suspended by the carriage bar 21 and conveyed to the spinning machine, and the spinning bobbin hangers 11 in the front row of the spinning machine are spun. Preliminary roving bobbin FB facing the roving bobbin B
Becomes In this state, the preliminary roving bobbin FB waits for a time to be replaced with the spun roving bobbin B in the front row. The traveling clearer 28 continuously travels along the spinning machine, blows out an air flow from its outlet, and blows down cotton wool such as creel. Due to this air flow, the roving thread end R wound on a part of the preliminary roving bobbin FB is peeled off and hangs down as shown in FIG. Further, this roving yarn end is blown toward the spun roving bobbin B on the front side by the downward blowing air flow, but is blocked by the separate plate 24 and the rotating portion of the bobbin hanger 10 of the spinning bobbin hanger row 11. (Hanger body 10d
And cylinder 10c) does not adhere. Therefore, it does not wind around the hanger body 10d or the like, and the roving thread end does not get stuck between the hanging rod 10a and the integral cap 10f, and the hanger body 10d or the like does not cause rotation failure. As a result, the spun roving bobbin B does not cause a rotation failure, and breakage of the supply braid and the like are eliminated. Naturally, the spare roving bobbin FB is also not rewound illegally.

In the present embodiment, the bent tip of the separate plate 24 is located at the same height as the upper brim 26 of the spun roving bobbin B. However, the bent tip is located at the lower brim of the preliminary roving bobbin FB. Department
When the height is the same as 32, it is possible to effectively prevent adhesion of the roving end R from the preliminary roving bobbin FB to the roving outer circumference of the spun roving bobbin B, which is more preferable. Also, this separate plate 24
You may hang straight down without bending.

As described above, according to the device of the present invention, the bobbin hangers of the front row spinning bobbin hangers and the preliminary roving bobbins are located at the height positions corresponding to the rotating portions of the bobbin hangers of the front row spinning bobbin hangers. Since the separate plate that separates the lower end from the both is provided continuously along the longitudinal direction of the creel, the spare roving bobbin can be easily and inexpensively constructed by the traveling clearer and the airflow from the factory air conditioning. Even if the roving ends are peeled off and hang down and blown toward the bobbin hangers of the spinning bobbin hanger row, they do not reach the bobbin hangers of the spinning bobbin hanger row, and can be prevented from being wound around them. Therefore, the bobbin hanger of the spinning bobbin hanger row is not rotated poorly, and breakage of the roving yarn supplied from the spun roving bobbin can be eliminated. Moreover, it is possible to avoid the situation in which the preliminary roving bobbin is unwound illegally, and it is possible to eliminate the shortage of roving during spinning.
