[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carding condition analyzing device which is used by being mounted on a cylinder peripheral surface of a carding machine of a spinning machine.

[0002]

2. Description of the Related Art Conventionally, the carding condition of a carding machine can be determined only by observing the quality of the carded fiber or judging from the worn condition of the metallic wire.

[0003]

However, in order to analyze the carding state by the above-mentioned conventional method, it is necessary to measure the nep of the card sliver or the yarn quality when the yarn is processed, which is very troublesome. Was there.

Further, the cylinder rotation speed, the doffer rotation speed,
In order to determine the spinning conditions such as the take-in speed, spinning amount, lap ounce, etc., it is necessary to measure the card sliver quality and yarn quality by the above method for each condition and determine the spinning conditions from the results. However, there is a problem that the work is very complicated and takes a lot of man-hours.

[0005]

According to the present invention, in order to solve the above problems, a fixed flat formed by attaching a strain gauge to a side surface of a bar main body is arranged at a predetermined position on a cylinder peripheral surface of a carding machine. , A carding condition analyzing device in which a strain gauge and a recorder are connected to a strain gauge.

The fixed flat is composed of a mounting base having a required radius of curvature and having bolts planted on the upper surface, and a bar having mounting brackets at both ends and metallic wires arranged on the back surface. The bar bracket is attached to the bolt of the mounting base, and the bar is tightened with a nut so that the position of the bar can be adjusted.

[0007]

Since the carding condition analyzing apparatus of the present invention has the above-mentioned structure, the carding force between the cylinder and the flat, which is the main function of the carding machine, is quantitatively measured by the strain gauge attached to the side surface of the fixed flat. Be recorded and recorded. By recording the measured values under various spinning conditions and calculating the relationship with the card slide quality, it is possible to determine, for example, the appropriate specifications of the cylinder metallic wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a carding state analyzing device of the present invention will be described below with reference to the drawings. As shown in FIG. 1 and FIG.
A metallic wire 2 is detachably arranged on the back surface of the bar body 1, and mounting brackets 3 are integrally fixed to both ends. The mounting base 4 has a radius of curvature substantially equal to the curve radius of the front concentric bend or back concentric bend of the carding machine, and a bolt 5 for mounting the top bar 1 is detachably planted on the upper surface thereof. ing. Further, the mounting base 4 is provided with mounting bolt holes 6 for mounting to the carding machine.

The mounting bracket 3 provided on the top bar 1 is loosely fitted to the bolt 5 of the mounting base 4 constructed as described above, and the adjusting nuts 7 and 7 are screwed on the upper and lower sides of the bracket 3 and tightened and fixed. , The bar 1 is mounted on the mounting base 4 in a positionally adjustable manner to form a fixed flat 8.

Further, as shown in FIG. 2, a strain gauge 9 is attached to the side surface of the bar body 1, and as shown in FIG. 3, the strain gauge 9 is provided with a strain measuring instrument 10, an A / D converter 11, a personal computer 12 and an XY. Recorder 1 consisting of plotter
3 is connected to form the carding state analysis device of the present invention.

The carding condition analyzer of the present invention was measured by placing a fixed flat on the cylinder peripheral surface between the top and the take-in, as shown in FIG. In addition, the personal computer is designed to be able to calculate and control the relationship between various spinning conditions, quality after spinning, etc. after measuring the amount of strain.

Measurement example 1 Spinning conditions Spinned fiber: rayon 1.5d × 51mm Spinning gel: 600g / 6yd Cylinder speed: 220 rpm Doffer rotation speed: 12 rpm Takein rotation speed: 360 rpm (A), 540 rpm (B) Wrap ounce: 14oz / yd

As shown in FIG. 5, the take-in speed is 54
It can be seen that at 0 rpm (B), the amount of strain is small because the fibers of the cylinder are made uniform, and the variation in the amount of strain is small, and an effective carded state is obtained.

Measurement Example 2 Spinning Conditions Spinning Fiber: Cotton 40th Spinning Gelene: 360 gr / 6 yd Cylinder Rotational Speed: 450 rpm Cylinder Metallic Wire Working Angle: 73 ° (A), 63 °
(B) Doffer rotation speed: 30 rpm

As shown in FIG. 6, the cylinder metallic wire having a working angle of 73 ° (A) has a much lower strain amount than the bar having a working angle of 63 ° (B). When the cylinder rotation speed of a cylinder metallic wire with a working angle of 73 ° is increased to 450 rpm, the cylinder metallic wire does not easily hold the fibers and there are many floating fibers. That is, the working angle of 73 ° is the cylinder rotation speed of 45.
It can be seen that it is not adapted at 0 rpm.

EFFECT OF THE INVENTION Since the carding condition analyzing apparatus of the present invention analyzes the strain amount of the fixed flat having the above-mentioned construction and the metallic wire is arranged, the carding condition can be easily and quantitatively grasped. It is also possible to select spinning conditions that give the best carded state by computer analysis.

Further, since the conventional rotary flat is not used, the analysis of the carding state can be measured by the above-mentioned simple device, and the fixed flat mounting structure is simple and the gauge can be easily adjusted. It is an invention having an excellent effect of.
