Description

[Detailed Description of the Invention] The present invention relates to a sizing liquid rectifying device for a sizing machine.

A sizing machine is a machine that improves the strength of the warp threads by impregnating the warp threads with a sizing liquid such as polyvinyl alcohol or starch before loading them into a loom. As shown in Figure 1, the sizing machine includes a plurality of beam stands 1 for unwinding the thread, a sizing part 2 for sizing the thread, and a dryer cylinder part for drying the sizing thread with steam. 3 and a winding part 4 for winding the dried thread. In the operation of the sizing machine configured in this way, for example, a yarn sheet with a total of 5,000 warp yarns from 10 coarsely wound beams (500 yarns per coarsely wound beam) is polypolymerized in the sizing part 2. It is immersed in a mixed size liquid such as vinyl alcohol and starch, and after being sufficiently soaked in the mixed size liquid, it is squeezed with a press roll. This press roll is installed in one or two stages. After this press roll dryer cylinder part 3 (or hot air dryer)
The thread is then dried in a sheet and wound onto a beam in winding part 4. By the way, glue part 2
As shown in FIG. 2, it is made up of an upper roll 5 and a lower roll 6 disposed above and below, an immersion roll 7 disposed in front of these rolls, and a glue patch 9 that stores mixed glue 8. Composed of 10 threads
is immersed in a mixed size liquid 8 with an immersion roll 7, and then squeezed (pressed) with an upper roll 5 and a lower roll 6. According to such a conventional configuration, the upper roll 5 and the lower roll 6
As the pressure between both rolls 5 and 6 increases,
The mixed size liquid 8 squeezed between them flows back on the surface of the immersion roll 7, and the thread 10 enters between the guide roll 11 and the immersion roll 7.
Collision A with the seat of At this time, the mixed size liquid 8 flowing backward becomes a flow layer with unevenness in the width direction, and this uneven flow layer induces disturbance in the sheet of yarn 10. If the yarn sheet is disturbed in the width direction in this way, the yarns will rub against each other when passing between the upper roll 5 and the lower roll 6, resulting in quality deterioration. Recently, due to high speed and high pressure drawing,
The roll diameters of the upper roll 5 and the lower roll 6 have become larger due to design, and the position of the lower roll 6 has become higher than the size liquid level compared to the past. Therefore, when the operation is stopped for a short time due to thread breakage or the like, the glue on the thread above the glue liquid level tends to dry out, and the thread 10 sticks to the surface of the lower roll 6, reducing the quality of the thread.

In the pasting part of the pasting machine, an immersion roll is installed in front of the press roll section made up of an upper roll and a lower roll, and a rectifying plate that can be adjusted up and down is placed above the immersion roll. This paper proposes a sizing liquid rectifying device for a sizing machine that is installed over the entire length in the width direction. According to this configuration, the sizing liquid that flows backwards on the upper surface of the immersion roll is distributed between the immersion roll and the rectifying plate. The yarn passes through the formed gaps that are uniform in the width direction, so the flow layer can be made uniform in the width direction and disturbance of the yarn sheet can be prevented. It is possible to increase the level of glue liquid in the machine and prevent the thread from drying out when the machine is temporarily stopped.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Here, 2 is a sizing part, 5 is an upper roll, 6 is a lower roll, 7 is an immersion roll, 8 is a sizing liquid, 9 is a sizing part, and 10 is a thread. The upper roll 5 and the lower roll 6 are supported by the frame 12 through bearings, and are forcibly rotated by being interlocked with a rotational drive device. Further, the immersion roll 7 is supported by a bracket 13 installed on the frame 12 so as to be freely rotatable. Above the immersion roll 7, a rectifying plate 14 that can be adjusted up and down is installed over the entire length in the width direction. This current plate 14 is attached to the bracket 13 with bolts and nuts 15, and the bracket 13
It is constructed so that the vertical position can be adjusted using a long hole formed in the.

In the above configuration, the thread 10 to be glued passes under the immersion roll 7, is immersed in the size liquid 8 stored in the glue pad 9, passes between the upper roll 5 and the lower roll 6, and is squeezed. . The size liquid 8 squeezed at that time is transferred to the current plate 1 by the presence of the current plate 14.
4 and both rolls 5 and 6, and the glue liquid level in that area is raised. Further, the accumulated size liquid passes between the immersion roll 7 and the current plate 14 and flows back uniformly in the width direction.

According to the present invention having the above configuration, the size liquid flowing backward on the upper surface of the immersion roll passes through a uniform gap in the width direction formed between the immersion roll and the current plate, and therefore the size liquid flows By making the layer uniform in the width direction, it is possible to prevent the yarn sheet from being disturbed, thereby preventing a decrease in quality. In addition, the level of the size liquid on the inlet side of the press roll section can be raised by the current plate, which allows the yarn to remain immersed in the size liquid even when the operation is temporarily stopped, and prevents the yarn from drying. Deterioration of yarn quality due to this can be prevented.
