Further, the rotation speed control device 44 for each spindle drive motor has a switching unit 44a that constitutes a switching unit, and switches the output to the spindle drive motor 6 according to the rotation direction set by the operation unit 48. It has become.

The operation unit 48 is connected to the host CPU 36 (rotation direction setting means) constituting the central control unit, and can set and change the rotation direction of the spindle drive motor 6 by operating keys. . In addition, the range in which the rotation direction can be set is collectively set according to various modes such as each rotation speed control device 44 for each spindle drive motor, each span composed of a plurality of spindle drive motors, or all spindle drive motors 6, and the like. It can be easily set. For example, when twisting from the first weight to the 64th weight by S twisting, the rotation direction is set to S twisting by operating the keys of the operation unit 48, and then “1” and “64” are input. With this, the range can be set and changed.

The operation unit 48 sets and changes the number of rotations for each of the rotation speed control devices 44 for each spindle drive motor and for each span of the plurality of spindle drive motors 6 in the same manner as for the setting and change of the rotation direction. Alternatively, all the spindle drive motors 6 can be set and changed collectively. still,
During winding, no setting or change is accepted even if the rotation direction and the number of rotations are set or changed.

Next, the host CPU 36 transmits the rotation direction setting data set / changed by the operation section 36 to the communication line 46 (rotation direction setting means), the repeater 45 (rotation direction setting means), and the communication line 51 (rotation direction setting means). The setting is transmitted to the switching unit 44a via the setting unit. The rotation direction setting data includes data (rotation speed No.) for specifying the rotation speed control device 44, data (spindle No.) for specifying the spindle, and data indicating the rotation direction (S twist or Z twist). ).

A rotation direction changeover switch 50 constituting a rotation direction setting means is connected to the rotation speed control device 44 for each spindle drive motor one by one via a validity changeover switch 56. The rotation direction switch 50 has an S twist switch and a Z twist switch. When the operator presses either the S twist switch or the Z twist switch, the switching unit 4 is switched via the validity switch 56.
The rotation direction setting data is transmitted to 4a.

The validity changeover switch 56 is a switch for fixing the rotation direction in a hardware manner regardless of the setting by communication from the host CPU 36. Whether to switch or not. That is, when the validity changeover switch 56 is valid (in the ON state), the rotation direction setting data by the rotation direction changeover switch 50 is changed to the changeover unit 4.
4a, and is not transmitted to the switching unit 44a when the validity changeover switch is ineffective (in an OFF state).

The switching unit 44a is connected to the host CPU 36
Alternatively, the switching order of the power elements for driving the spindle drive motor 6 is changed according to the rotation direction setting data received from the rotation direction switch 50. When the rotation direction is set or changed by the rotation direction switch 50, the rotation direction is switched by giving priority to the rotation direction setting data by the rotation direction switch 50.

That is, when the validity changeover switch 56 is valid (in the ON state), the changeover section 44a receives the rotation direction setting data from the rotation direction changeover switch 50 and rotates the spindle drive motor 6 in the set direction. If the validity changeover switch is invalid (OF
F state), the host CPU 36 sends the communication line 51
The spindle drive motor 6 in the rotation direction set via
Is to be rotated. As described above, the rotation speed control device 44 for the spindle drive motor switches the rotation direction (output) of the spindle drive motor 6.

The operation of the single-spindle drive type multi-twisting machine 1 in the above configuration will be described with reference to the drawings. The operator operates the operation unit 4 of the host CPU 36 as shown in FIGS.
8 is set to a desired state by operating the keys.
Here, an example will be described in which the first to 64th weights are set to S-twist and the others to Z-twist. The operator sets the rotation direction to S twist by operating the keys of the operation unit 48,
Enter "1" and "64". When the operator completes the input, the host CPU 36 transmits the input rotation direction setting data to each repeater 45 via the communication line 46. Then, each repeater transmits the rotation direction setting data to each rotation speed control device 44. When the switching unit 44a of each rotation speed control device 44 receives the rotation direction setting data, the setting of the rotation direction is completed.

Next, when the operator starts the operation of the single-spindle drive type multi-twisting machine 1, the converter 35, the DC bus 47, the DC transformer 43 for the spindle device from the AC power source 34.
, A DC voltage of 24 V is supplied to each rotation speed control device 44. Further, a start command is transmitted from the host CPU 36 via the control signal line 54 to each of the relay connector boards 5.
3 and transmitted simultaneously from each relay connector board 53 to the rotation speed control device 44 for the spindle drive motor via the control signal line 55. Each spindle drive motor 6 is driven based on a start command from each rotation speed control device 44, and each rotating disk 33 rotates at the same rotation speed as each spindle drive motor 6. Each rotating disk 33
Is rotated, the yarn Y unwound from the yarn supply package 8 is rotated.
Enters the tensioning device 32, is twisted once while being tensioned, and is twisted once more, so that the balloon guide 3
Balloon up to 7.

On the other hand, from an AC power supply 34, a converter 35,
A DC voltage of 290 V is supplied to the rotation speed control device 41 for the winding drum drive motor via the DC bus 47, and a start command is sent from the host CPU 36 to the rotation speed control device 41 via the control signal line 54. Sent. The take-up drum drive motor 4 is driven based on a start command of the rotation speed control device 41, and its output is output to each of the pulleys 10, 12, 16
・ 19 ・ 22 ・ 24, Belt 11.14 ・ 20 ・ 25,
Each of the support shafts 18 via the speed reducer 17 and the cam box 27
The traverse guide 29 of each weight reciprocates while the winding drum 21 and the feed roller 26 of each weight rotate while being transmitted to the reciprocating rod 23 and the reciprocating rod 28.

When the winding drum 21 of each weight and the feed roller 26 rotate and the traverse guide 29 of each weight reciprocates, the yarn Y twisted twice by the spindle device 2 is moved to the traverse guide 29. Is wound around the winding package P while being traversed. In the traverse, the traverse angle is corrected by the speed reducer 17.

As a result, since the rotation direction of each spindle drive motor can be set arbitrarily and wound,
A wide variety of winding packages P can be produced. Further, when setting / changing the rotation direction, the rotation direction setting data is transmitted to the plurality of rotation speed control devices 44 via the repeater 45, so that the operation unit 48 connected to the host CPU 36 controls the rotation direction. Settings can be easily made collectively. Further, even when a number of winding units U are arranged in rows, each rotation speed control device 4
4 can surely receive the rotation direction setting data via the repeater 45, so that the omission of the rotation direction command can be prevented.

On the other hand, due to a trouble in the communication lines 46 and 51, for example, the rotation speed control device 4 of the first to sixteenth weights is used.
When the rotation direction setting data set by the key operation of the operation unit 48 cannot be received, the operator sets the validity changeover switch 56 of the first weight to the sixteenth weight to an effective state (ON state). The S direction is set by the rotation direction switch 50.

Thus, even when a trouble occurs in the communication system, the validity switch 56 is enabled (ON).
State), the setting / change can be performed by the rotation direction switch 50. Note that, in a normal case where the rotation direction is set by a key operation of the operation unit 48, the validity switch 56 is in a non-valid state (OFF state).

The control power supply line 49 of the multiple twisting machine 1 according to the present embodiment is connected to a control system voltage (24 V) for controlling the spindle drive motor 6 by each of the rotation speed control devices 44.
It is for supplying to. The control signal lines 54 and 55 are for transmitting a start command or a stop command to the total rotation speed control devices 41 and 44, and are for transmitting a simultaneous start or simultaneous stop signal of a normal machine. Things. Further, the communication lines 46 and 51 are used to monitor the number of revolutions of each motor 6 and command values for each motor 6 by the host CPU 36, and to control the control parameters from the host CPU 36 to the respective revolution number control devices 41 and 44. It is for setting.

In this embodiment, since two spindle drive motors 6 are connected to the spindle drive motor rotational speed control device 44, the minimum unit that can be set or changed in the rotation direction is each spindle drive motor. For each rotation speed control device 44. Therefore, although it can be set and changed in units of two spindles, it is needless to say that it can be set and changed in units of one spindle as needed. During operation, the communication line 46 is used for extracting the number of rotations of the spindle device 2 from each winding weight, monitoring for occurrence of an abnormality, and the like.

In this embodiment, the rotation speed control device 44 for the spindle drive motor is described as constituting each unit control section 9 for every 32 units.
Is not limited to 32. In addition, although it has been described that two spindle drive motors 6 are connected to the rotation speed control device 44 for the spindle drive motor, the number of spindle drive motors is not limited to two. Furthermore, a case has been described in which a single yarn supply package 8 is provided in each yarn winding unit U, but the present invention is not limited to this, and a plurality of yarn supply packages may be provided. The above D
The C brushless motor has a built-in sensor (not shown) for detecting its rotation speed.

In the multiple twisting machine 1 according to the present embodiment,
Although the double twisting machine in which the twisting is performed twice by one rotation of the spindle device 2 has been described, another triple or quadruple twisting machine may be used. In the present embodiment, the switching unit 44a
Although the switching direction has been described as the S-twist and the Z-twist, the switching unit 44a may be any unit that switches between the forward direction and the reverse direction.
