Description

[Detailed description of the invention] Industrial application field This invention is a double twisting machine, especially a double twisting machine that has spindle rows on the front and back sides of the machine stand. This invention relates to a double twisting machine that can handle a wide variety of products and is capable of twisting yarns of different standards.

〓Conventional technology〓 In conventional double twisting machines, a drive belt is run through a spindle on the front side and a spindle on the back side of the machine base, and the spindles on the front side and the back side are rotated simultaneously. Therefore, only the same standard of yarn can be twisted on the front and back sides, and when producing a wide variety of products in small quantities, one machine must be used for each product, resulting in a lot of waste.

〓Problems to be solved by the invention〓 The purpose of this invention is to obtain a multi-product production type double twisting machine that can perform twisting of different specifications on the front side and the back side of the machine stand.

〓Means for solving the problem〓 A pair of vari-pitch pulleys are provided between the main motor and the input pulley for the spindle row on the front side of the machine, and between the main motor and the input pulley for the spindle row on the back side of the machine. A pulley system was provided, and each pulley system was configured to be driven by the main motor.

〓Operation〓 By rotating the spindle on the front side of the machine stand and the spindle on the back side in accordance with the respective twisting conditions, yarns of different standards can be twisted on the front side and the back side of the machine stand.

〓Example〓 Embodiments of this invention will be described below with reference to the drawings.

The double twisting machine 1 of this invention has spindles 3a, 3b, 3 on the front side of the machine via a cam box 2.
A pulley system 4 is installed in a drive system that drives a spindle row consisting of 6a, 6b, 6c, . A pulley system 7 is provided. A belt 12 is installed between the pulley 9 of the main motor 8, the vari-pitch pulley 10 of the pulley 4, and the vari-pitch pulley 11 of the pulley 7.

The pulley system 4 is constructed by installing a belt 15 between another vari-pitch pulley 13 coaxially with the vari-pitch pulley 10 and a vari-pitch pulley 14 that transmits rotation to the cam box 2. Since they are configured to be relatively changeable, the rotation of the vari-pitched pulley 14 can be arbitrarily changed by changing the rotation ratio between the vari-pitched pulley 13 and the vari-pitched pulley 14.

Similarly, the other pulley system 7 includes another variable pitch pulley 16 coaxially with the variable pitch pulley 11.
A belt 18 is installed between the cam box 5 and a vari-pitched pulley 17 that transmits rotation to the cam box 5, and since the vari-pitched pulley 16 and the vari-pitched pulley 17 are configured to be able to relatively change their pulley diameters, the vari-pitched pulley 16 and The rotation of the vari-pitch pulley 17 can be changed arbitrarily by changing the rotation ratio of the vari-pitch pulley 17.

19 is another pulley coaxial with pulley 9 of the main motor 8, and drives a counter pulley 21 via a belt 20. Further, 22 and 23 are the double twisting machine 1 whose rotation is adjusted by the cam box 2 or 5.
This is a belt mounted between an input pulley 24 that transmits information to the spindle rows 3a, 3b, 3c, .

Therefore, the rotation ratio of the vari-pitch pulleys 13, 14 of the pulley system 4 on the front side and the rotation ratio of the vari-pitch pulleys 16, 17 of the pulley system 7 on the back side are made different, and the spindle on the front side of the machine and the spindle on the back side are made different. and can be separate rotations.

〓Effects of the invention〓 As described in detail above, the double twisting machine of this invention has two main motors and an input pulley for the spindle row on the front side of the machine base, and an input pulley for the main motor and the spindle row on the back side of the machine base. A pulley system consisting of a pair of vari-pitch pulleys is provided on both sides between the pulleys, and each pulley system is configured to be driven by the main motor, so the pulley system consists of a pair of vari-pitch pulleys on the front side and a pair of vari-pitch pulleys on the rear side. The pulley system can give different rotations to the spindle on the front side of the machine and the spindle on the back side of the machine, and as a result, the spindle on the front side of the machine and the spindle on the back side of the machine can be rotated separately according to the respective twisting conditions. This rotation makes it possible to twist yarns of different specifications on the front and back sides of the machine, making it possible to use a single double-twisting machine to handle a wide variety of products.
