Description

[Detailed description of the invention] The present invention relates to a yarn guiding device for introducing yarn into a heater that heat-treats the yarn, and which facilitates the operation of guiding the yarn to the heater located at a high position. The purpose of this is to improve the contact of the yarn to the heater and to prevent deterioration of the quality of the yarn.

In order to guide the yarn to the heater that heat-treats the yarn, it is common practice to install a yarn guide near the outlet of the heater, but generally the heater is long and installed in a vertical position. Because of this, the thread guide was installed at an extremely high position, and the operator had to sit on the workbench and stretch his or her upper body to operate the thread hook, making it extremely difficult to operate.

Therefore, in the device of the present invention, a yarn guide is provided at the tip of a support arm that is pivoted to a lifting member that can be moved up and down according to a guide rail, and when the support arm is placed above the heater, it extends from the front of the heater to a slightly rear side. In addition, the lifting member is provided with an operating rod for raising and lowering the member, and when the operator raises and lowers the operating rod, the yarn guide at the tip of the support arm is raised via the lifting member. It descends and guides the thread into the heater.

An embodiment of the device of the present invention will be described below with reference to the drawings.

The heat treatment apparatus 1 shown schematically in FIG. 1 has a passage 2 in the center, and a heater 3 and a winding device 4 are installed on both sides of the passage 2. The treatment system 5 that exits the heater 3 is heated beyond the upper part of the passage 2. It is wound up by a winding device 4 through a device and the like.

In the heat treatment apparatus 1, the heater 3 is usually erected vertically.

Therefore, when leading out the yarn from the heater 3, the heater 3
A yarn guide 6 for guiding the yarn above the heater 3 must be provided near the outlet of the heater 3.

Also, when hanging the thread on the thread guide 6,
It is better for the yarn guide 6 to be located below the outlet of the heater 3, so in that case the yarn guide 6 must be lowered.

For this purpose, the yarn guide 6 is supported in the passage 2 in front of the heater by a guide member 7 so as to be able to move up and down with respect to the heater outlet.

The guide member 7 is supported by a support member 8 in front of the heater 3.

A guide rail 9 is supported by a support member 8, and has a guide plate 10 on its upper part.

An elevating member 11 is slidably fitted into the guide rail 9, and a yarn guide support arm 12 is swingably supported on the elevating member 11 by a shaft 13.

The shaft 13 is provided with a spring 14 whose end portion is locked to the yarn guide support arm 12 and the elevating member 11, and urges the yarn guide support arm 12 to rotate counterclockwise in FIG. .

A fitting piece 16 having a groove 15 is supported by a screw 17 on the yarn guide support arm 12 so that the groove 15 and the edge of the guide plate 10 come into contact when the yarn guide support arm 120 turns counterclockwise. Make it.

Reference numeral 18 denotes a second yarn guide provided on the yarn guide support arm 12.
It is de.

A lifting member operating member 2 is connected to the lifting member 11 by means of a bottle 19.
Connect the operating rod as 0.

21 is a guide piece for the rod 20.

A stopper 22 is provided at the upper end of the guide rail 9, so that when the elevating member 11 comes into contact with it, the tip of the leaf spring 23 touches the elevating member 1.
1 to prevent it from falling.

The apparatus of the present invention is configured as described above, and the processing system 5 is normally subjected to heat treatment in the state shown in FIGS. 1 and 2.

If the thread breaks and it becomes necessary to pass the thread through the heater 3 anew due to thread breakage or other reasons, the operating member 2
By pulling 0, the lifting member 11 is pulled down along the guide rail 9.

As the elevating member 11 is pulled down, the thread guide support arm 12 is also pulled down, and the arm 12 is urged by the spring 14 so as to press the button in FIGS. 1 and 2 and rotate counterclockwise. Since the fitting piece 16 that is integrated with the arm 12 is in contact with the lower edge of the guide plate 10, as the elevating member 11 descends, the thread guide support arm 12
stands up, and the yarn guide 6 approaches the guide rail 9 and comes to be located on the same line as the guide rail 9.

Therefore, the yarn guide 6 is separated from the heater 3, and is located within the passage 2, making it easier for the operator inside the passage 2 to carry out operations such as threading.

When the above-mentioned work is completed in the passage 2, the operating member 20 is pushed up and the elevating member 11 is raised, and the fitting piece 16 rises along the guide plate 10, contrary to the above, and the thread that was in the upright state is lifted up. The thread guide support arm 12 falls down, and the thread guide 6 advances to the far right in FIG. 2, that is, deeper than the actual position of the thread guiding groove (not shown) of the heater 3.

Then, at the position where the elevating member 11 has risen the most and is in contact with the stopper 22, the recess 24 of the elevating member 11 and the protrusion of the leaf spring 23 fit together, so that the elevating member 11 is prevented from falling and is stopped and fixed. Ru.

As explained in detail above, in the device of the present invention, by simply operating the operating rod of the slider operating member 20 up and down, the yarn guide can be moved between the back side of the yarn guide groove of the heater 3 and the front side of the heater. It is possible to move back and forth between the working passages, and when threading the yarn guide 6, by pulling the yarn guide 6 down into the working passage, you can work in the normal posture within the working passage, increasing work efficiency. be able to.

In addition, the processing target system is installed at the back of the heater 3 by means of a yarn guide.
By pushing the yarn away from the heater, not only is the contact between the heater and the yarn ensured and the yarn can be completely heat-treated, but also the yarn guide support arm 12 supported by the shaft 13 is Since the fitting piece 16 of the arm 12 is fitted with the guide plate 10, the arm 12 is fixed at two points, the shaft 13 and the fitting piece 16, and the thread guide 6 provided at its tip is fixed. Even when the yarn guide support arm 12 comes into contact with a yarn running at high speed, the yarn guide support arm 12 does not vibrate at all, and the quality of the yarn while it is running does not deteriorate σ.

Furthermore, since the second yarn guide 18 is provided at a position away from the tip of the yarn guide support arm 12, the guiding angle of the yarn buttoned at the zero portion of the yarn guide at the tip of the arm must be set large. This also prevents deterioration of yarn quality caused by bending the yarn at a steep angle.
