Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyeing machine for dyeing an annular yarn bundle.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a dyeing machine for fitting an annular yarn bundle onto a dyeing liquid jetting cylinder to dye the yarn bundle.

The dyeing machine is provided with a dyeing liquid supply pump for discharging the dyeing liquid from the dyeing liquid jet cylinder.

[0004]

By the way, the applicant is
As a result of various trials, it was confirmed that, when the yarn bundle was dyed with such a dyeing machine, the yarn was fluffed and damaged, or the yarn was entangled, resulting in uneven dyeing.

As a result of detailed examination of this, the following conclusions were obtained.

A conventional drive motor that has existed in the past has a characteristic that the rotation increases at the time of rising and then decreases after a while to settle down. This means that when the drive motor is started, the dyeing liquid ejecting cylinder first vigorously ejects the dyeing liquid (more than necessary dyeing liquid is ejected), and after a while, the dyeing liquid ejection state becomes appropriate. Means that.

Therefore, this early jetting of the dyeing liquid causes fluffing and damage of the yarn, entanglement of the yarn, and uneven dyeing.

The present invention provides a dyeing machine which solves such drawbacks.

[0009]

The gist of the present invention will be described with reference to the accompanying drawings.

In the dyeing machine for dyeing the yarn bundle 1 by covering the yarn bundle 1 with the ring-shaped yarn bundle 1 on the rod-like dyeing liquid jet body 2,
A control unit for controlling the initial dyeing liquid discharge flow rate of the dyeing liquid supply pump 3 for injecting the dyeing liquid from the inside is provided, and the dyeing liquid discharge flow rate is appropriate so that the yarn is not damaged or the yarn is not entangled. The present invention relates to a dyeing machine, characterized in that the control section is configured as a control section using an inverter so as to be controlled.

[0011]

The initial flow rate of the dyeing liquid discharged from the dyeing liquid supply pump 3 is properly controlled by the control unit using the inverter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings illustrate one embodiment of the present invention and will be described below.

A reference numeral 5 is a container, and a rod-shaped dyeing liquid ejecting body 2 is laterally provided on the container 5, and the dyeing liquid supplying pump 3 is connected to the dyeing liquid ejecting body 2 via a communication pipe 6. ing.

The drive motor 7 of the dye supply pump 3 is a drive motor incorporating an inverter, and the rotation speed of the drive motor 7 is controlled.

Further, reference numeral 8 is a rotating member which can rotate the dyeing liquid ejecting body 2 to change the dyeing position. still,
Reference numeral 4 denotes a dye injection hole, and the position of this dye injection hole 4 is the dyeing position.

Since the present embodiment has the above-mentioned structure, several dyed yarn bundles 1 are set on the dyeing liquid ejecting body 2, the dyeing liquid supplying pump 3 is operated, and the rotating member 8 is rotated appropriately. When the yarn bundle is tightened, the yarn bundle 1 is dyed.

At this time, the frequency of the drive motor 7 of the dye supply pump 3 of the present embodiment is controlled by the inverter, so that the rotational speed of the drive motor 7 can be controlled appropriately by the inverter. It is possible to prevent the dyeing liquid from being jetted vigorously from the dyeing liquid jetting hole 4 in the initial stage of operation, that is, the dyeing liquid jetting state from the dyeing liquid jetting hole 4 can be gradually raised to an appropriate jetting state, Therefore, the damage due to the fluffing of the yarn, the entanglement of the yarn, and the like do not occur at all, and uneven dyeing can be prevented as much as possible.

[0018]

Since the present invention is constructed as described above,
It is a dyeing machine that can prevent damage due to fluffing of yarn, entanglement of yarn, and uneven dyeing as much as possible.
