Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a single-spindle type double twister, in particular, a large number of unit bodies are arranged in parallel, and each unit body twists the spun yarn and winds the twisted yarn. This invention relates to a single-spindle type double twister in which each spindle can handle different types of yarn.

[Prior Art] A double twister, which is generally known as a device for twisting spun yarn and making the twisted yarn into packages, constitutes one machine in which a number of unit bodies are arranged in parallel.

This double twister has a configuration as shown in FIG. 3.

As shown in the figure, the double twister a has a large number of unit bodies b arranged side by side to form one machine, and each unit body has a spindle rotating at its lower part to spin the spun yarn. A spindle unit for twisting is provided, and the spindle is engaged with a belt c running over a number of spindles and driven to rotate. Also,
A winding unit is provided at the upper part of the unit body a, and in this winding unit, a rotating drum is rotated to turn the twisted yarn into packages.

[Problems to be solved by the invention] By the way, as mentioned above, the spindle of the spindle unit is a belt c that runs over many spindles.
Since the spindle is driven by the spindle, the feed roller, traverse device, etc. provided on the winding side follow this and are all driven at the same time. Therefore, when handling different types of yarn, it is impossible to handle different types of yarn at the same time with one double twister because the handling conditions such as winding speed are different for each type. For this reason, in the conventional double twister, yarns of the same type are handled, and there is a problem in that changing the type of yarn requires a long time.

In addition, since all the spindles are driven by a single drive motor d, the capacity of the drive motor d increases and the size of the drive motor d increases, so a large amount of space is required to secure the drive source box e. I had a problem.

The present invention was created to effectively solve the above problems.

This invention makes it possible to drive each spindle independently in a double twister in which a large number of unit bodies are arranged in parallel and each unit body has a spindle unit and a winding unit, and enables high-speed winding according to the type of yarn. To provide a single spindle type double twister which can easily adapt to multiple spindles and shorten the time required to change threads.

[Means and effects for solving the problems] The present invention has a large number of unit bodies arranged in parallel, each of which rotates a spindle unit that twists the spun yarn by rotating a spindle unit and a rotating drum. In a double twister having a winding unit for winding the twisted yarn, a drive motor for rotating the spindle independently for each spindle unit and a rotation speed control device for controlling the rotation speed of the motor are provided, Each winding unit is equipped with a drive motor for independently driving the rotating drum and a rotation speed control device for controlling the rotation speed of the motor. It is possible to adapt to winding conditions according to the type of product, easily adapt to a large number of spindles, and achieve a reduction in space.

[Example] An example of the present invention will be described in detail below with reference to the accompanying drawings.

FIGS. 1 and 2 show a unit body 1 of a double twister according to the present invention, and a large number of unit bodies 1 are arranged side by side to constitute one machine.

A spindle unit 2 for twisting the spun yarn is provided at the lower part of the unit main body 1, and this spindle unit 2 has a balloon restricting cylinder 4 that accommodates a spinning bobbin 3. A spindle 5 is rotatably inserted in order to twist the spun yarn.

Further, a winding unit 6 for winding up the twisted yarn is provided at the upper part of the unit main body 1.

The winding unit 6 is provided with a rotating drum 8 that contacts the winding package 7 and rotates it, and is provided with a traverse device 9 for traversing the twisted yarn in the axial direction along the rotating drum 8. A feed roller 10 is provided which rotates and follows the rotating drum 8.

In particular, in this invention, the spindle unit 2
A drive motor 11 is connected to the spindle 5 of the winding unit 6, and a drive motor 12 is connected to the rotating drum 8 of the winding unit 6, the traverse device 9, and the feed roller 10, which drives the belts 13a, 13b, etc. These drive motors 11 and 12 are connected to a rotation speed control device (inverter) 14, depending on the type of yarn.
The rotation speed is controlled by 15.

In other words, a large number of unit bodies 1 are arranged side by side,
A drive motor 11 for rotationally driving the spindle 5 and a rotation speed control device 14 for controlling the rotation speed of the motor 11 are provided for each spindle unit 2 of each unit body 1, and a rotation speed control device 14 for controlling the rotation speed of the motor 11 is provided for each spindle unit 2 of each unit body 1. A drive motor 12 for driving the rotating drum 8 and a rotation speed control device 15 for controlling the rotation speed of the motor 12 are provided. A source is provided.

Therefore, each of the unit bodies 1 arranged in large numbers in parallel has a driving source, and is separated from each other in terms of power and is provided independently.
Each weight will be driven independently.

By making it possible to drive each spindle independently in this way, when handling different types of yarn, it is possible to handle each spindle for each type. That is, since individual winding conditions etc. can be set for each spindle, it is possible to wind yarn at high speed depending on the type of yarn, and it is also possible to use a large number of spindles at the same time. Even when changing the type of yarn, it can be handled in a short time.

Furthermore, since the driving power is small, small-capacity drive motors 11 and 12 can be used, and the unit can be made compact and does not require a large installation space.

Furthermore, the number of operating spindles can be set according to the amount of yarn produced; for example, 50 out of 60 spindles can be operated, and the other 10 spindles can be stopped together with the drum and spindle, achieving energy savings. .

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) Since each weight is driven independently, each weight can handle different types of yarn, and depending on the type of yarn, high-speed winding is possible.

(2) Can be easily handled with multiple spindles.

(3) Can respond to changes in yarn types in a short time.

(4) Since each unit main body is driven independently, the unit can be made compact and space-saving can be achieved.

(5) The number of operations can be set according to the production amount of yarn, and a predetermined number of operations can be performed while the remaining spindles, both the drum and spindle, can be stopped, achieving energy savings.
