Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spindle plate driving device for a torsion lace machine and a braiding method using the device.

[0002]

2. Description of the Related Art As a torsion lace machine for manufacturing a torsion lace by braiding knitting yarns, one disclosed in Japanese Patent Publication No. 1-59374 is known. According to this race machine, the rotation of the rotary plate (corresponding to the spindle plate) on which the bobbin is erected is rotatably supported by the driving motor about the machine axis of the race machine as the rotation center. The rotation transmitted to the annular gear) is transmitted to the bobbin connecting gear (corresponding to the clutch gear) from the composition vehicle set (corresponding to the intermediate gear), and is fitted coaxially with the rotating shaft of the bobbin connecting gear. Obtained by being transmitted to a rotating dish. On the other hand, the rotary plate is subjected to intermittent drive control for every half rotation corresponding to the handle construction by the rotation selection mechanism of the bobbin connecting gear, and the lace fabric is braided.

[0003] The driving of the spindle plate in torchon lace machine shown in Japanese Utility Model 61-230 3 4 discloses the rotating annular gear from the drive motor in the same manner as described above in lace machine, via the intermediate gear It is transmitted to the drive gear (corresponding to the clutch gear), and by performing up / down drive selection control corresponding to the structure of the shifter fork, the on / off state of the clutch is intermittently made every half rotation, and odd-numbered and even-numbered spindles are used. By rotating the plates alternately by half a turn, the positions of the bobbins fitted in the yarn guide spindle installed upright on the spindle plate and arranged in a circle are exchanged, and the braided yarn fed from the bobbin is entangled. Braided.

In both of the two torsion race machines described above, a constant rotational movement from the drive motor is transmitted to the clutch gear for each spindle plate, and the rotation is arbitrarily selected by each clutch action. The crossing and non-crossing of the bobbins are controlled, whereby the pattern of the torsion lace fabric is formed.

[0005]

The yarn guide spindle, in which the spindle plate and the bobbin rotated by the spindle plate are fitted, in these race machines is forced to repeat rotation-abrupt stop-abrupt start. In addition, the braiding speed is suppressed as compared with a braiding machine that repeats constant rotation of the bobbin, and the noise caused by the mechanical contact collision sound with the yarn guide spindle accompanying the sudden stop and sudden start of the spindle plate is large. In addition, since various connecting parts from the driving motor, annular gears, intermediate gears, clutch gears, clutches, shifter forks, and various members constituting the shifter fork vertical drive selection device are required, the structure is extremely complicated and many parts are required. Was needed.

Further, since the clutch gears are connected to each other on the circumference of a circle having the center of the machine shaft as a center, the clutch gears in the odd-numbered rows and the even-numbered rows rotate in the opposite directions. The rotation directions of them are always the same, and the rotation direction of the spindle plate that is coaxial with the rotation axis of the clutch gear is always the same direction. become.

The present invention solves the above problems, softens the impact of the spindle plate during braiding, and significantly reduces the components of the torsion lace machine to simplify the structure, thereby reducing noise during braiding. At the same time, we will try to improve the braiding speed.

Another object of the present invention is to provide a torsion race machine capable of arbitrarily controlling the rotation direction of the spindle plate regardless of whether it is an odd row or an even row.

[0009]

According to the present invention, the drive source of the spindle plate is provided individually or separately, and the rotation of each spindle plate can be arbitrarily selected to rotate normally or reversely. Is.

With this construction, the rotation of the spindle plate can be freely selected between forward rotation and reverse rotation in an optional braiding course, so that the upper and lower relationship of the entanglement of the braided yarn due to the reversal of the adjacent bobbins can be arbitrarily changed. .

By adopting a stepping motor or a servo motor as a drive source for each spindle plate, the start and stop of the rotation of the spindle plate can be configured to be a smooth motion by electronic control. Will be alleviated.

Since the rotary shaft of the spindle plate is directly connected to the drive shaft of the drive source, various members for transmitting the motion from the drive motor to the spindle plate, which are conventionally required, are not required, so that the structure is extremely simplified. , The sources of noise and vibration are reduced.

Further, by connecting the rotary shaft of the spindle plate to the drive shaft of the drive source through an intermediate transmission means such as a timing belt or a gear, the installation space can be effectively used even if the drive source has a large capacity. Can be used.

Obviously, by alternately providing the one directly connected to the drive source and the one through the intermediate transmission means, the space in the horizontal direction can be effectively used.

Further, when the main body of the torsion race machine is stopped,
Since all yarn guide spindles have fixed point stopping means that stops on the circumference of a circle centered on the machine axis, braiding is possible from the specified position when starting next time, so the handle Normal braiding is continued without any damage.

In the braiding method using the above spindle plate driving device, the upper and lower relations of the entanglement of the braided yarns drawn out from the bobbin are selected by selecting the normal rotation and the reverse rotation of the spindle plate in an arbitrary braiding course. By freely changing and braiding, it is possible to simultaneously braid one fabric made of the braiding yarn and another fabric made of the braiding yarn that is partially independent of the fabric. It is possible to configure the relief pattern, which was not available in the above, at an arbitrary position.

Further, a patent acquired by the applicant (Japanese Patent Publication No.
-43659), the structure can be simplified by driving corresponding spindle plates in the inner and outer spindle rows with a single motor such as a pulse motor.

[0044]

According to the drive device for the spindle plate in the torsion lace machine of the present invention, the rotation of each spindle plate in any course and in any arrangement can be selectively controlled, so that the entanglement of the braided yarn can be performed at a free position. Since it can be implemented, there are no restrictions on braiding.

Since the spindle plate is directly connected to the drive means or via the minimum intermediate transmission means, the structure is extremely simple and the number of parts used can be reduced.

By using a servo motor as the driving means,
Since the speed control of the start and stop of the spindle plate can be performed, the vibration and noise of the race machine can be suppressed in combination with the simplification of the structure of the drive part, which can contribute to the improvement of the braiding speed. Became.

Further, according to the braiding method of the present invention, the interlacing of the braided yarns can be freely performed by freely selecting the left and right rotations of the spindle plate so that an independent braided portion can be freed by the ground braided portion which cannot be achieved by the conventional lace machine. It is possible to braid a torsion lace fabric that has a free pattern in a wide pattern area.
