Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a false twisting apparatus for applying a false twist to a synthetic fiber yarn in a draw false twisting machine or a false twisting machine.

[0002]

2. Description of the Related Art In general, when two yarns of a synthetic fiber yarn are combined, each yarn is false-twisted by two false-twisting units arranged side by side in a lateral direction, and then the yarn is twisted. The yarn is wound up. When two false twist units are mounted on one support member, a bearing and a rotation transmitting pulley and belt are provided between the rotor of the driving motor and the disk mounting portion. I'm sorry.

[0003] Power is supplied to the motors by individually connecting a connector provided at an end of a cable drawn from each motor and a connector provided for each motor provided on a cable on a power supply side. .

In recent years, in order to reduce the space of the false twisting device section and make the entire false twisting machine compact, two false twisting units as described in, for example, Japanese Patent Publication No. 1-37491 are arranged in front, rear, left and right. There are known ways to do this. In this case, a space for introducing the yarn into the back side false twisting unit must be secured between the back side false twisting unit and the near side false twisting unit. Are shifted in the left-right direction. A method is also known in which the arrangement of the two false twist units is shifted in the front-rear and up-down directions.

[0005] The supporting member on which the false twisting unit is mounted is attached to a machine frame of the drawing false twisting machine or the false twisting machine with bolts. Also, JP-A-11-107087
A method of moving two false twist units relative to each other as described in Japanese Patent Application Laid-Open Publication No. H11-260, has been proposed.

[0006]

In the former case of the conventional false twisting apparatus, the false twist is applied by the two false twisting units which are separately arranged in the lateral direction, and then the yarn is twisted. There is inefficiency that only half of the thread can be wound.

In the latter case, since the bearing, the pulley and the belt for transmitting the rotation are provided between the rotor of the electric motor and the disk mounting portion, it is very difficult to replace the bearing and the belt. There is a problem.

Further, since the electric motor and the shaft of the disk mounting portion are separate members, there is a problem that the configuration becomes very complicated in order to easily and surely align the two. .

Furthermore, since the rotor of the electric motor is in a cantilever state, it is necessary to increase the shaft diameter of the shaft body in order to increase the speed, resulting in a problem that the entire device becomes large.

In order to supply power to the motors, the connector provided at the end of the cable drawn from each motor and the connector provided on the cable on the power supply side are individually connected to each other. In addition to this, there is a problem that the connection space must be accommodated, and the connection work of the connector must be performed in a narrow place, and the connection work is very difficult.

When two false twisting units are arranged in front and rear to reduce the space of the false twisting unit, it is necessary to secure a space for introducing the yarn into the false twisting unit on the back side. The two false twisting units are displaced in the front-rear, left-right, or front-rear, up-down directions. In addition, the arrangement pitch of the false twisting units tends to be narrowed to increase the number of false twisting units to be arranged. There is a problem that the space for introduction is lost and the yarn cannot be introduced. Further, when two false twisting units are arranged in front and rear and up and down, there is a problem that the yarn quality is changed because the two yarn paths are greatly different, and the yarn quality after combining is deteriorated.

[0012] Since the conventional false twisting device is operated only in a state of being fixedly installed on the machine frame, when the front false twisting unit needs to be threaded to the back side false twisting unit during false twisting, the false twisting unit is not used. There is also a deficiency that it must be performed between the yarns being twisted. Further, even when the two false twisting units are relatively moved, a space for threading in the false twisting device can be secured, but the space between adjacent false twisting units is narrow, and workability is poor.

In any of the above-described false twisting devices, the supporting member can be directly attached to the mounting member of the drawing false twisting machine or the false twisting machine, so that the operator can support the heavy false twisting device by hand. It is necessary to attach to the attachment member with bolts or the like, and there is a problem that the attachment / detachment operation is extremely dangerous when the drawing false twisting machine or the false twisting machine is in operation.

According to the present invention, the entire apparatus is compact and can cope with high-speed operation, and can easily perform assembling work, repair work and connector attaching / detaching work, and furthermore, Z twist and S twist for each false twist unit. It is an object of the present invention to provide a false twisting device that can arbitrarily perform switching, starting, and stopping, and can easily perform yarn hooking to the front and rear false twisting units.

[0015]

According to a first aspect of the present invention, there is provided a false twist device in which one of the shafts is rotated by an electric motor and the other is rotated by a rotation transmitting member. At the same time, two false twist units, which are arranged so that the rotor of the electric motor is located between the bearings, are mounted on one support member.

Further, the false twisting device of the present invention is configured such that the false twisting device can be moved between an operation position and a yarn introduction position as described in claim 2, and can be operated and stopped at either position. The power supply to the two electric motors according to claim 3 is performed by a connector provided on a support member for mounting one motor and a power supply side provided on a mounting member for mounting the support member. In this configuration, the two motors can be individually switched between forward rotation, reverse rotation, and stop as described in claim 4.

Further, in the false twist device in which the two false twist units are attached to one support member back and forth, the yarn introduction portion of the back false twist unit is positioned with respect to the plane vertical line. At 10 to 90 degrees.

Further, the false twisting device of the present invention is provided in a bearing provided at a predetermined interval such that at least two shafts protrude at one end in a state of being substantially parallel. Thus, the shafts are rotatably mounted on the support members, and the shafts are rotated by an electric motor, and a plurality of disks are alternately positioned on the protrusions of the shafts. Two false twist units are mounted on one supporting member, and the engaging protrusion formed on the supporting member has a guide groove for engaging the protrusion, or The guide groove for engagement formed in the support member may be configured to be attached to the frame of the stretch false twisting machine or the false twisting machine by an attachment member having a projection for engaging the guide groove.
