Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 to 3 is a view showing the automatic dispensing device for warp knitting machine according to the present invention, the automatic dispensing device of the warp is inclined to be sent from the warp beam (1) used in warp knitting machines, such as ratchet machine, double ratsel machine, etc. After sensing the tension of (2) to calculate the amount of inclination to send, and to control the rotation of the inclined beam (1), it is to adjust the amount and tension of the inclination (2) used for the fabric to be constant.

That is, the inclined automatic transmission device of the present invention has a load cell 11 for detecting the tension of the inclination (2) is installed on the inclined exit side of the inclination beam (1), and receives the signal output from the load cell (11) A controller 12 for outputting an ordinary signal is connected to the load cell 11, a motor 13 driven by an electrical signal of the controller 12 is connected to the controller 12, and the motor 13 The speed reducer 14, which varies the number of revolutions of the motor, is coupled to a motor shaft (not shown) of the motor 13.

And the present invention is an example of the power transmission means for transmitting the rotational force output from the reducer 14, the pulley 15, the pulley-shaped frequency adjusting member 16 and the belt 17 to adjust the frequency regulator 18 The rotation speed of the driving motor 19 is varied by the frequency adjusted by the frequency controller 18, and the tilted beam 1 is rotated by the driving motor 19.

Here, the tip of the load cell 11 is connected by a tension bar 11a and a spring 11b for adjusting the tension of the inclination 2 transmitted from the inclination beam 1 so as to sense the tension of the inclination 2. do.

The controller 12 receives an electric signal that is variable in the load cell 11 and compares it with a set value and outputs the electric signal to the motor 13. In this embodiment, the main controller 3 is already installed. It can be connected with.

In addition, the controller 12 allows a user to input a limit value and the like, and processes the input unit 12a connected to the load cell 11 and the signal input from the load cell 11 to tension the tilt 2. Is calculated, and then compares the calculated value with the set value inputted by the input unit 12a and calculates a comparison value, and a comparison value connected with the main controller 4 and calculated by the calculation unit 12b. The driving unit 12c is configured to output a signal for driving the motor 13 by determining whether the current rotational speed is variable.

Of course, as shown in FIG. 1, the power transmission means has a pulley shape for adjusting the frequency of the frequency regulator 18 and a pulley 15 connected to the shaft 14a on the output side of the speed reducer 14. The frequency adjusting member 16, and the belt 17 is connected to the pulley 15 and the frequency adjusting member 16 to transmit the rotational force of the pulley 15 to the frequency adjusting member 16.

In addition, although the power transmission means is not shown, it is apparent that the pulley 15 and the frequency adjusting member 16 can be replaced with a sprocket shape and the belt 17 can be replaced with a chain.

Furthermore, as shown in FIG. 2 as another example, the power transmission means is engaged with the worm 20 and the worm 18 connected to the shaft 14a on the output side of the reducer 14, and the frequency regulator 18 It may be made of a frequency control member 21 of the worm gear shape to adjust the frequency generated in the).

In the automatic transmission device for warp knitting machine according to the present invention made as described above, after the user driving the warp knitting machine inputs the set value of the warp tension according to the material of the warp through the input unit 12a of the controller 12, the warp knitting machine is operated. In this case, the tension of the inclination is adjusted.

That is, the inclination (2) made of fabric by the needle is constantly sent out from the inclined beam (1), but the amount of delivery is variable with the passage of time and the tension of the inclination is variable, at this time the load cell 11 is inclined Sensing the tension of (2) and outputs a variable current to the input unit 12a of the controller 12.

Then, the calculating unit 12b of the controller 12 calculates the electric signal from the load cell 11 input to the input unit 12a as the inclined tension, compares the calculated tension with the set value, and determines the comparison value by using the driving unit ( 12c).

The driving unit 12c may vary the electrical signal currently driving the motor 13 according to the comparison value and output the electrical signal to the motor 13 again.

Then, the motor 13 generates a rotational force, and the rotational force adjusts the frequency controller 18 through the power cutting means, and the rotation speed of the drive motor 19 is varied by the frequency controller 18. As a result, the rotational speed of the inclined beam 1 is varied so that the amount of transmission of the inclined beam is variable.

In other words, when it is calculated as a comparison value that the inclination tension is greater than the set value, a signal for increasing the rotational speed of the driving motor 19 is output from the driving unit 12c, so that the frequency controller 18 is variable, and thus the driving motor 19 When the number of rotations is increased to increase the amount of output of the inclination (2), and when it is calculated as a comparison value that the tension of the inclination is smaller than the set value, a signal for reducing the number of rotations of the driving motor (19) is output from the driving unit (12c) and the frequency The regulator 18 is variable, thereby reducing the amount of rotation of the drive motor 19 to reduce the amount of delivery of the inclination 2.

For example, as the fabric manufacturing process proceeds, the stacking amount of the warp yarn 2 wound on the warp beam 1 becomes smaller, and the amount of warp output from the warp beam 1 that is rotated in the same state as the initial state is relatively small. It acts in the direction of increasing tension on the slope.

Then, the load cell 11 outputs an electric signal to the controller 12 according to the change in tension, and the controller 12 compares and calculates the set value and the tension set by the user to determine the rotation speed of the drive motor 19. The increasing signal is output to the motor 13, and the motor 13 operates the frequency adjusting members 16 and 21 by a power transmission means, and the frequency adjusting member controls the frequency regulator 18. The drive motor 19 is controlled to drive at an increased speed.

Accordingly, the tension of the inclination 2 decreases, and when the tension decreases, the load cell 11 continuously detects the result, and as a result, the rotation speed of the driving motor 19 is continuously changed, and thus the tension of the inclination is kept constant. The amount of inclination is kept constant.

Thus, the device for adjusting the inclination of the inclination according to the present invention can continuously control the number of rotations of the inclination beam according to the change in the inclination of the inclination so that the amount of inclination can be kept constant.

As described above, the warp automatic transmission device for warp knitting machine according to the present invention is because the load cell detecting the tension of the warp output from the warp beam outputs an electrical signal to the controller to continuously vary the number of revolutions of the warp beam, By automatically adjusting the rotation of the inclined beam continuously, there is an advantage that the amount of inclination and the tension from the inclined beam can be kept constant.

Furthermore, since the amount and tension of the warp yarn can be kept constant, even if the fabric is made of spandex yarn having excellent elasticity, the quality of the fabric can be kept constant and the quality of the fabric can be kept constant. There are further advantages such as being able to easily improve the quality.
