Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mule spinning machine, and in particular to a sliver spinning machine.
The present invention relates to a carriage traverse device.

(Conventional technology) Traditionally, mule spinning machines used a spindle for twisting and winding.
The so-called intermittent twisting, which is carried out in the outer and inner stages of the Key II range, is carried out using a method. Therefore, the longer the stretch of the spindle is, the fewer times the spindle carriage traverse is turned back during the formation of one comb, and the twisting is more efficient. In addition, in this method, even if the twisting speed is increased, the tension of the yarn is generally soft and the occurrence of yarn breakage is small, and the twisting time for one string can be shortened.

The sliver carriage traverse drive source connects a single row roller chain to the spindle carriage.
This is a traverse mechanism in which the connection point of the chain moves back and forth on a straight chain by reversing the chain wheel.

With this traverse mechanism, when the speed ratio of the spindle carriage and the sliver carriage is 1:1, the time required for spindle stretching can be shortened most as described above.

(Problems to be solved by the invention) As mentioned above, in a mule spinning machine, the longer the spindle wrench is, the more efficient the twisting is, and the twisting time can be shortened, but in wool spinning Since braided yarn is made from a wide variety of raw materials, if it is placed on a storage stand that is too long, the quality of the yarn may deteriorate due to uneven twisting, etc.

Also, if the speed ratio of the spindle carriage and sliver carriage is set to 1=1, the spindle
Since the speed ratio of the self-propelled carriage and the outward movement of the carriage is approximately 2:1, the self-propelled speed of the interlocking sliver carriage is also high, and the sliver carriage is suddenly turned back or stopped at the fixed position at the end of the white road. I need to brake. This is to maintain a constant distance between the sliver delivery front roller and the spindle when they are closest to each other. That is, when the distance between the sliver delivery front roller and the spindle when they are closest to each other becomes narrower, the thread wound around the spindle is pulled back, producing a snarl. On the other hand, if the spacing is wide, the tension of the thread will be strong and the thread will break more often. In response to this, it is possible to install various types of shock absorbing braking devices, but slight differences in adjustment may cause shock to the sliver carriage, causing the front top row and sliver to fall, and damage to the sliver carriage. occurs and is undesirable.

The object of the present invention is to provide a sliver carriage traverse device for a mule spinning machine that can be set to slitch to slitch suitable for a wide variety of roving yarns and can increase production capacity.

(Means for Solving the Problems) As a means for solving the above problems, the first invention provides a mule spinning machine in which the spindle carriage and the sliver carriage are tuned in opposite directions. This is a sliver/kilage/rubber device characterized in that a spindle carriage that traverses by stretching can be set to a stretch suitable for roving by setting an arbitrary set speed ratio to the spindle carriage.

Further, a second invention provides a mule spinning machine in which the spindle carriage and the sliver gear traverse in synchronization in opposite directions, in which two belts or chains for driving the traverse of the sliver key iz carriage are hooked in parallel; During the parallel arrangement, a traverse block is loosely supported and combined with the sliver carriage traverse guide, and the inner traverse end of the sliver carriage 1~rubber guide is connected to the traverse drive bell 1~
- A sliver carriage traverse device characterized in that one of the wheels coincides with the rubber dead center.

(Example) The present invention will be described below based on drawings showing examples. In the figure, 1 is a spindle carriage, on which is mounted a spindle 2, front roller 3, front top roller 4, sliver roller 5.
, is interlocked with a sliver carriage 7 equipped with a sliver spool stand 6. Sliver Ki Oni! Rage 7
has a sliver carriage wheel 8 which is connected to a traverse guide 9 so as to be able to traverse on a rail 10. 36 is a sliver. The spindle carriage 1 has a spindle carriage 11 and is driven by a headstock 37,
It is possible to traverse the length of the rail 12.

Brackets 13 are provided at the front and rear of the spindle carriage 1, to which both ends of a timing belt 14 are respectively fixed. The timing belt 14 is engaged with timing belt pulleys 15 and 16 on the left and right sides of the figure. The timing belt pulley 15 is attached to a shaft loosely supported by a bracket 17, and the other timing belt pulley 16 is attached to a back shaft 19 whose one end is loosely supported by a bracket 18. ing. Furthermore, one back shaft has
Traverse drive gear 2 via bearing 20
1 is attached and the other i~rubber drive 1! that engages with it! The gear 22 is connected to a transmission 23.

The transmission 23 is provided with a timing pulley 24, and a timing belt 26 is engaged between it and a timing pulley 25 provided on the right side of the rail 10 (as shown). A shaft 27 to which a timing pulley 25 is coupled and supported is loosely supported by a bearing 28,
A double chain wheel 29 is attached to the opposite end.

Two chain wheels 30 are also provided on the opposite side of the chain wheel 29, and two chains 31 are suspended between them in parallel.

A sliver gearage traverse block 32 is held at one location of the parallel chains 31 and loosely supported by a bin. The chain wheel 30 is loosely supported on studs 34,35 supported on the bracket 33;
The sliver key 17 is designed to be able to turn back at the traverse dead center of the chain 31. That is, the chain 31 is hung so that the traverse block 32 coincides with the traverse dead center. As a result, the traverse block 32 is driven by the reverse drive of the chain 31.
It slides in the longitudinal groove 9a of the traverse guide 9 coupled to the sliver gearage 7, causing the sliver gearage 7 to traverse.

The position of the outer end of the sliver gearage 7 is on the straight line of the traverse chain and can be arbitrarily set by changing the 1-rubber speed ratio with the spindle gearage 2. Instead of the chain 31, it is also possible to use an endless bell i~.

In the mule spinning machine configured as described above, by providing a transmission between the traverse mechanism of the spindle gearage and the traverse mechanism of the sliver gearage, the spindle gearage and sliver V yarnage can be changed to 〇~1: It is possible to set any speed ratio in the range of 1 to a stretch suitable for any braided yarn.

In addition, by setting the speed ratio to 1:1, the traverse speed is twice that of a mule spinning machine that has only spindle gearage traverse or sliver carriage traverse, which doubles production as the spindle rotation speed increases. be able to.

Furthermore, by attaching the sliver gearage traverse drive roller chain to the two water exchange rows, the traverse block can be loosely supported at one point between the parallel roller chains, allowing the sliver gearage traverse to move freely. - In combination with a guide, the internal position of the sliver key 17 can be aligned with the traverse dead center of the traverse chain wheel. Thereby, the sliver gearage gradually automatically decelerates near its end position during inward movement, and can turn around with the traverse dead center of the traverse chain wheel at the inward end position. At the turn, Yu returns to the constant traverse speed. Further, the stop position of the outer end of the sliver gearage is on the straight line of the traverse chain as described above, and can be arbitrarily determined according to the setting of the speed ratio of the spindle clearage in accordance with the conditions of the thread braiding, etc.
