DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laying head for continuously forming a wire into a wire.

[0002]

2. Description of the Related Art A laying head of this type includes a rotating body having a rotating shaft having a wire introduction port on one end face and a face plate connected to the other end of the rotating shaft, and a rotating rod arriving at the wire introduction port being rotated by the rotating shaft. A J pipe for guiding the wire rod out of the rotary shaft, an S pipe for guiding a wire rod guided to the outer peripheral surface of the face plate to a position close to the outer peripheral surface of the face plate, and a driving unit for rotating the rotary shaft. The wire entering the center hole of the rotating shaft from the wire introduction port enters the S pipe through the J pipe, is sent out of the S pipe by the spiral bending and centrifugal force of the S pipe, and has a ring-shaped winding habit. The wire is spirally fed from the face plate to form a wire coil. When a wire conveyed spirally from a face plate is received by a continuously moving conveyor, the wire is fed in a spiral loop shape. For example, in the surface treatment of a rolled wire, the wire is spirally wound on a conveyor by a laying head.
And sent to a surface treatment step by a conveyor.

[0003]

The laying head is driven to rotate at a high speed, the peripheral speed of the face plate is high, and the feed speed of the wire is high. Vibration is great if the rotation balance of the laying head is poor. By the way, since the S pipe and the J pipe have no symmetry with respect to the rotation center axis, and the wall thickness is also different in the longitudinal direction, and further, the S pipe and the J pipe are worn out due to friction with the wire rod. It is easy to lose balance. That is, it is easy to vibrate. Although the laying head is regularly replaced, vibration may occur even immediately after the replacement. Therefore, for example, 90
At a wire winding speed exceeding m / sec, the vibration of the laying head becomes excessive, and stable wire winding is difficult.

An object of the present invention is to suppress the vibration of the laying head even at a relatively high rotational speed.

[0005]

Balance controller 29 and position controller
The controllers 17A to 17D mainly include a CPU (microprocessor) and include electric control circuit elements such as a power supply circuit, an input / output interface, and a communication controller, and a communication control circuit element. -La 2
The control operations of 9, 17A to 17D are provided by the CPU. Next, these control operations will be described.

The operating voltage is applied to the electric circuit and the sensor. In response to the voltage application, the balance controller 29 and the position controllers 17A to 17D execute initialization,
Then, the balance controller 29 waits for a control ON instruction from the laying head control panel.

The position controller 17A (the other 17
When the initialization is completed, the electric motor 14A is driven to rotate in the normal direction, and during that time, the rotary encoder 15A is driven.

When the limit switch 21A is switched from on to off by moving outside of A, the electric motor 14A is stopped there and the data (count value) of the count register is written into the position register. Then, the electric motor 14A is driven to rotate in the reverse direction, during which the rotation synchronization pulse generated by the rotary encoder 15A is counted down (decrement of the count register). When the count value of the count register becomes zero, the electric motor is there. Stop the data 14A . As described above, the balance weight 20A returns to the position before the driving, and the data indicating the position (radial direction) of the balance weight 20A starting from the limit switch 21A (point 0) is set in the position register. Become. Next, the position controller 17A sets data indicating "ready" in the output register, and waits for the transfer of control data addressed to its own name from the balance controller 29.

When a control-on instruction is given to the balance controller 29 from the laying head control panel, the balance controller 29 sequentially sends data to the position controllers 17A to 17D in a predetermined cycle to their names. Data frame including control data and inquiry data (control data transfer frame)
And the bit configuration are the same) on the serial two-way communication line (one of the brushes). Position controller 1
7A (similarly for the other 17B to 17D), upon receiving the data frame, if the destination data in the data frame designates itself, the destination data of the received data frame is designated. Change the balance controller 29 to one that specifies it, and change the "control data" (inquiry data at this point) of the received data frame to the data of the "output register". , To the communication line.

The balance controller 29 outputs "ready" data from all the position controllers 17A to 17D.
After receiving the data transfer, the balance control starts.
If there is a position controller that did not transfer the "ready" data, destination data indicating the position controller and an "error"
Send the data to the laying head control panel. The laying head control panel displays an "error" display and information (No.) for specifying the position controller of the error on a display panel (not shown).

Now, all the position controllers 1
When "Ready" data is received from 7A to 17D,
The balance controller 29 executes the following (A).

(A) The sampling timer is started, and when the photosensor 26 detects the reflection plate 25 (first detection), the accumulation registers 27θ and 28θ.
And the rotation speed register are cleared. Photo sensor 26
In response to the second and subsequent detections of the reflection plate 25, first, it is checked whether or not the content of the rotation speed register is "8".
Otherwise, the content of the rotation speed register is incremented by one and the angle register is cleared,
While the 6 does not detect the reflector 25, the rotary encoder
Each time the encoder 13 generates one pulse, the content of the angle register is incremented (counted up) by one, and the detected values of the eccentric meters 27 and 28 are converted into digital data and read. The detected value of 27 is accumulated in an accumulation register 27θ assigned to the displacement meter 27 and specified by the data in the angle register (rotation angle θ). And the data in the angle register
Accumulation register 28 specified by data (rotation angles θ = 0 to n)
Integrate with θ.

If the content of the rotation speed register is 8 when the photo sensor 26 detects the reflection plate 25, the data difference between the accumulation register 28θ and the accumulation register 27θ having the same rotation angle is calculated and the rotation is performed. Is written to the difference register θ corresponding to the angle, and the upper part of the data of the difference register θ (θ = 0 to n)
The peak value Du and the lower peak value Db are searched for and their angles θ
u and θb (θ value; register storing peak value)
Ask for. Next, a peak-to-peak deviation Du-Db is calculated, and it is checked whether it is within a set range (permissible range). If it is out of the set range, the balance weight is set within a range of θu ± 45 °. 20A to 20D is checked, and data (control data frame = instruction) for instructing the balance weight 20i (i = A to D) to be driven up (outward) within the range. It generates frame head information + name-addressed i data + up drive required + frame end information) and sends it to the communication line to the position controllers 17A to 17D. Further, the balance weight 20A is set within the range of θb ± 45 °.
20D is checked, and data (control data frame = frame) for instructing the down (inward) drive of the balance weight 20j (j = A to D) within the range is checked. -Head information + j address data + down drive required + frame
END information is generated and transmitted to the communication line to the position controllers 17A to 17D.

The position controller 17i which has received the up-drive instruction data drives the motor 15i one rotation forward. During this drive, the contents of the position register are counted down in response to the rotation synchronization pulse generated by the rotary encoder 15i, and the count value becomes 0 (outer limit position).
Or the limit switch 21i
Is switched from closed to open, the motor 14i
To stop. When the count value does not become 0 and the switch 21i is not opened and the one-rotation forward drive is completed, the position controller 17i executes the execution completion data (frame head information + data addressed to 29 persons + ready data). + Frame end information) to the communication line. That is, it is transmitted to the balance controller 29. When the motor is stopped due to the count value becoming 0 or the switch 21i being opened, unexecutable data (frame head information + data addressed to 29 persons + error + frame) -End information) to the communication line.

The position controller 17j, which has received the down drive instruction data, drives the motor 15j to rotate in the reverse direction by one rotation. During this drive, the contents of the position register are counted up in response to the rotation synchronizing pulse generated by the rotary encoder 15j, and when the count value reaches the set value (inner limit position), the motor is there. Stop 14j. When the one-rotation reverse drive is completed without reaching the set value, the position controller 17j executes the execution completion data (frame data).
(Data + ready + frame end information) to the communication line. That is, it is transmitted to the balance controller 29. When the set value is reached and the motor is stopped, unexecutable data (frame head information +
(Data + error + frame end information) to the communication line.

(B) The execution completion data is received from the position controller 17i, and the position controller 17i receives the execution completion data.
When the execution completion data is received from the controller 17j, the balance controller 29 determines that the balance weight is within the adjustment range,
Since the adjustment is performed properly, the process waits for the sampling timer to time over, and when the sampling timer times over, the above (A) is executed. As long as the balance weight is within the adjustment range, the above (A) is repeatedly executed. That is, the above (A) is repeated at the period of the set time Ts of the sampling timer.

When the execution completion data is received from one of the position controllers 17i and 17j and the unexecutable data is received from the other, the balance adjustment of the reink head by adjusting the position of the balance weight is still possible. Therefore, the process is executed in the same manner as in (B) above, but when both of the position controllers 17i and 17j send unexecutable data, the balance adjustment of the re-ink head by adjusting the position of the balance weight. Has reached the limit, the balance controller 29 sends destination data indicating the position controllers 17i and 17j and "error" data to the laying head control panel. The laying head control panel has an "error" display on its display panel (not shown) and error position controllers 17i and 17j.
Is displayed. After that, the balance controller 29 does not resume the above (A) until a control-on instruction is given from the laying head control panel.
When the control ON instruction is given, the process proceeds to (A).

By the above-described control operations of the balance controller 29 and the position controllers 17A to 17D, the rotation angle 36 around the rotation axis 1 of the laying head is obtained.
When the uniformity of the weight distribution at 0 degree is lost and the rotational deviation of the face plate 5 exceeds the threshold value, the balance weight at the position where the balance weight swings away from the rotary shaft 1 automatically moves inward (in the direction approaching the rotary shaft 1). ), The balance weight on the side opposite to the position about the rotation axis 1 is driven outward (in a direction away from the rotation axis 1), whereby the weight distribution about the rotation axis 1 becomes more uniform, and the face plate 5 is smaller. The abrasion of the J pipe 6 and the S pipe due to the rubbing with the wire rod locally progresses, and the weight distribution becomes unbalanced. It is driven outward, and the increase in rotational shake of the face plate 5 is automatically suppressed. Therefore, the face plate 5 can be driven to rotate at high speed. That is, the transfer speed of the wire can be increased.

[0035]

As described above, according to the present invention, the imbalance of the weight distribution in the circumferential direction with respect to the center of rotation of the laying head can be compensated by adjusting the position of the balance weight, so that the speed of transferring the wire can be increased.
