Abstract

(57) [Abstract] [Purpose] To obtain a long fiber spinning machine having a deep depth spinning section with a small installation area and allowing an operator to safely work. [Structure] By making the inclination angle of the spinning section on the spinning machine stand substantially vertical, the depth of the machine stand is reduced, the installation area is reduced, and the workability of the operator is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a long fiber spinning machine.

[0002]

[Prior Art]

As shown in FIG. 2, the inclination angle θ ₂ of the spinning section 1 in the current spinning machine is set to about 45 degrees. However, when spinning long-fiber yarns, the gauge size becomes long, and a draft device with a large number of rolls, such as a 4-wire type or more, is often used for the draft device 2 in recent years. For example, the spinning device shown in Fig. 2 is used. When a drafting device such as a so-called 5-wire drafting device is adopted for the section 1, the depth of the spinning section 1 becomes deeper because the number of drafting rollers increases. As a result, the installation area increases, and when an operator located on the front side of the spinning machine works on the trumpet guide 4 or the like located near the back roller 3 or on the upstream side of the back roller 3, the work becomes difficult and the size is particularly small. Operators have come to be called upon to improve the spinning part 1 because it cannot reach the inner part of the spinning part 1 and it is dangerous.

[Problems to be solved by the device]

 It is an object of the present invention to obtain a long fiber spinning machine having a spinning section with a large number of rollers and a long drafting device, which allows an operator to safely work.

[0004]

[Means for Solving the Problems]

 The angle of inclination of the spinning section on the spinning machine base was set to be almost vertical.

[0005]

[Action]

 By making the inclination angle of the spinning section almost vertical, the machine base width, that is, the machine base depth is reduced to reduce the installation area and improve the workability of the operator.

[0006]

【Example】

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

The long-fiber spinning machine of the present invention is the same as the conventional long-fiber spinning machine except that the inclination angle θ ₁ of the spinning section 10 on the spinning machine base 21 is substantially vertical. That is, on the spinning machine stand, the sliver guide 11, the trumpet guide 12, the back roller pair 13a, the fourth roller pair 13b, the third roller pair 13c, the second roller pair 13d, and the front are arranged from the back of the machine stand toward the front. A five-wire draft device 13 including a pair of rollers 13e, in which an apron belt is mounted on the second pair of rollers and a fourth pair of rollers, an air spinning nozzle 14, and a delivery roller 15 are arranged in series to form a spinning section 10 And a winding device 16 for the yarn Y sent from the delivery roller 15 is provided below the front surface of the machine base. However, the spinning section 10 of the present invention is constructed such that the inclination angle θ ₁ is substantially vertical as shown in FIG.

In the figure, reference numeral 22 is a support box for holding the trumpet guide 12, the draft device 13, the air spinning nozzle 14, and the delivery roller 15 on the machine base 21. Reference numeral 23 is a yarn splicing carriage that travels in the machine base 21 in the direction perpendicular to the paper surface in FIG.

On the rear side of the machine stand, a can 17 containing a sliver S to be supplied to the spinning machine is placed via a can placement section 18, and a creel having a sliver guide 19 is provided above the can placement section 18. A device 20 is provided.

The sliver S drawn from the can 17 reaches the draft device 13 through the sliver guide 11 and the trumpet guide 12 while being mounted on the sliver guide 19 on the creel device 20, and is drafted by the draft device 13 and air-spun. The yarn Y is twisted by the nozzle 14 to form the yarn Y, and then the yarn Y delivered from the delivery roller 15 is wound around the bobbin 24 on the winding device 16 while forming the package 25.

As a result of various studies, the inclination angle θ ₁ of the spinning section 10 in the present invention is most preferably set to about 75 degrees, and the top roller is insufficiently held as it approaches a vertical direction of 75 degrees or more, and the top roller is not supported. The sliver nip force between the rollers and the bottom roller became uneven, and there was a risk that the sliver would not be drafted reliably, and the workability gradually deteriorated from 75 degrees toward the horizontal.

[Effect of the device]

 As described in detail above, in the long-fiber spinning machine of the present invention, since the tilt angle of the spinning section on the spinning machine base is set to be substantially vertical, the width of the machine base, that is, the depth of the machine base is reduced and spinning is performed. It is possible to reduce the installation area of the machine and increase the number of machines installed in a certain area, and the operator's work can be performed reliably and easily throughout the spinning section, eliminating the danger. Workability was improved and productivity could be improved.
