Abstract

PURPOSE:To restrain the vibration of a laying head even at the comparatively high rotating speed. CONSTITUTION:Balancing weights 20A-20D fitted so as to be possible to shift in the radial direction and be impossible to shift in the rotating direction to a rotary shaft 1, are fitted to rotary bodies 1-5 of the laying head. Further, weight driving means 14A-19A/14B-19B/14D-19D containing electric motors for driving the balancing weights 20A-20D in the radial direction, are fitted to the rotary bodies 1-5. Therefore, as the imbalance of weight distribution in the peripheral direction to the rotating center can be compensated by adjusting the position of the balancing weight, the carrying speed of a wire rod can be made to be high.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raying head for continuously imparting a ring-shaped curl to a wire.

[0002]

2. Description of the Related Art A raying head of this type is a rotating body having a rotating shaft having a wire rod introduction port at one end face and a face plate connected to the other end of the rotating shaft, and a wire rod coming to the wire rod introducing port. , A S pipe for guiding the wire rod guided to the outside of the rotating shaft to a position close to the outer peripheral surface of the face plate, and a driving means for rotationally driving the rotating shaft. The wire rod entering the center hole of the rotating shaft from the wire rod inlet enters the S pipe through the J pipe, is sent out from the S pipe by the spiral bending of the S pipe and the centrifugal force, and has a ring-shaped curl. A wire rod coil is spirally drawn from the face plate. When the wire rod spirally delivered from the face plate is received by the transport conveyor that continuously moves, the wire rod is sent in a spiral loop shape. For example, in the surface treatment of rolled wire rods, the wire rods are spirally rolled on a conveyor by a laying head.
It is sent out in the shape of a pipe and sent to the surface treatment process by a conveyor.

[0003]

The laying head is driven to rotate at high speed, the peripheral speed of the face plate is high, and the feeding speed of the wire is high. Vibration is large if the rotating balance of the raying head is poor. By the way, since the S pipe and the J pipe do not have symmetry with respect to the center axis of rotation, and the wall thickness also differs in the longitudinal direction, the S pipe and the J pipe are worn away due to friction with the wire rod, and therefore the raying head rotates It is easy to lose balance. That is, it easily vibrates. Although the laying head is regularly replaced, vibration may occur immediately after replacement. Therefore, for example, 90
When the wire winding speed exceeds m / sec, the vibration of the raying head becomes excessive and it is difficult to stably wire the wire.

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

When the ratio (L / D) of the distance L to the size D of the face plate (5) is large (> 1.0) and the rotation balance of the running head is lost, the above 1. According to the method for maintaining the rotational balance described in the paragraph, the bending moment due to the distance from the disc (18) on which the balance weight is attached to the center of gravity of the rotating shaft (1) depends on the amount of movement of the balance weight (20A, 20B).

A balance controller 29 and a raying head control board are connected to the brush 23 which contacts the slip ring 22. FIG. 6 shows a connection relationship between the balance controller 29 and the raying head control panel and the position controllers 17A to 17D by this connection. Balance controller 29 and position controller
Each of the controllers 17A to 17D is mainly composed of a CPU (microprocessor), and includes an electric control circuit element such as a power supply circuit, an input / output interface and a communication controller, and a communication control circuit element. -La 2
The control operation of 9, 17A to 17D is provided by the CPU. Next, these control operations will be described.

When the raying head control panel turns on (power supply) the power supply lines (two brushes) to the balance controller 29, etc., the balance controller 29 and the position controllers 17A to 17D and the connections to them are connected. The operating voltage is applied to the electric circuit and the sensor. In response to this 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 raying head control panel.

Position controller 17A (other 17
The same applies to B to 17D), after the initialization is completed, the motor 14
A is driven to rotate in the normal direction, during which the rotation synchronizing pulse generated by the rotary encoder 15A is counted up (increment of the count register), and the limit switch 21A is turned off by moving the balance weight 20A to the outside. When the switching is made, the motor 14A is stopped there, and the data (count value) of the count register is written in the position register. Then, the motor 14A is driven in the reverse direction, during which the rotation synchronizing pulse generated by the rotary encoder 15A is counted down (decrement of the count register), and when the count value of the count register becomes zero, the motor 15A is there. To stop. From the above, the balance weight 2
0A returns to the position before driving, and the position register has a balance weight 20 starting from the limit switch 21A (0 point).
The data indicating the position of A (radial direction) is set. Next, the position controller 17A sets data indicating "ready" in the output register, and waits for the balance controller 29 to transfer the control data addressed to its own name.

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 at predetermined intervals. And a data frame including inquiry data (control data transfer frame
And the bit configuration is the same) to the serial bidirectional communication line (one of the brushes). Position controller 1
7A (similarly for the other 17B to 17D), when receiving the data frame, if the destination data in it designates itself, the destination data of the received data frame is designated. The balance controller 29 is changed to a designated one, and the "control data" (inquiry data at this point) of the reception data frame is changed to the data of the "output register". , To the communication line.

The balance controller 29 is a "ready" data from all the position controllers 17A-17D.
"Balance control" starts when the data is transferred,
If there is a position controller that did not transfer the "ready" data, the destination data and "error" indicating that
Send data to the Raying Head Control Board. The raying head control panel displays "error" and information (No.) for specifying the position controller of the error on its display panel (not shown).

Now, all position controllers 1
When receiving "ready" data from 7A-17D,
The balance controller 29 executes the following (A).

(A) When the sampling timer is started and the photosensor 26 detects the reflector 25 (first detection), the accumulation register 27θ and the accumulation register 28θ are detected.
And clear the speed register. Photo sensor 26
In response to the detection of the reflecting plate 25 from the second time onward, first, it is checked whether the content of the rotation speed register is 8, and
If not, the rotation speed register contents are incremented by 1 and the angle register is cleared.
While 6 is not detecting the reflector 25, the rotary encoder
Every time the datum 13 generates one pulse, the content of the angle register is incremented (counted up) by one, and the detected values of the deviation meters 27 and 28 are converted into digital data and read. The detected value of 27 is accumulated in the accumulation register 27 θ which is assigned to the deviation meter 27 and specified by the data (rotation angle θ) of the angle register, and the detected value of the deviation meter 28 is the deviation meter 28. To the angle register data
Register (rotation angle θ = 0 to n)
Add to θ.

If the content of the rotation speed register is 8 when the photosensor 26 detects the reflection plate 25, the data difference between the accumulation register 28θ and the accumulation register 27θ of the same rotation angle is calculated to rotate. Write to the difference register θ corresponding to the angle, and select the difference register θ (θ = 0 to n)
Of the peak value Du and the lower peak value Db, and their angles θ
u and θb (θ value; register storing peak value)
Ask for. Next, the peak-to-peak deviation Du-Db is calculated, and it is checked whether it is within the setting range (allowable range). If it is outside the setting range, the balance weight is within the range of θu ± 45 °. It is checked whether any of 20A to 20D is present, and data (control data frame =) for instructing the up (outward) driving of the balance weight 20i (i = A to D) that is within the range is checked. (Frame head information + i data addressed to name + up drive required + frame end information) is generated and sent to the communication lines to the position controllers 17A to 17D. Furthermore, within the range of θb ± 45 °, the balance weight 20A
.. to 20D, the 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. -Frame top information + Named j data + Down drive required + Frame-
End information) and sends it to the communication line to the position controllers 17A to 17D.

The position controller 17i, which has received the up-driving instruction data, drives the motor 15i in the forward direction by one rotation. During this driving, the contents of the position register are counted down in response to the rotation synchronizing pulse generated by the rotary encoder 15i, and the count value becomes 0 (outer limit position).
The limit switch 21i
When is switched from closed to open, the motor 14i is there.
To stop. When the count value does not become 0 and the switch 21i is not opened and the one-turn forward rotation drive is completed, the position controller 17i executes the execution completion data (frame start information + data addressed to 29 persons + ready). + Frame end information) is sent 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, the 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 in the reverse rotation for one rotation. During this driving, 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. 14j is stopped. When the one-rotation reverse rotation drive is completed without reaching the set value, the position controller 17j causes the execution completion data (frame
Frame head information + data addressed to 29 persons + data + frame end information) are sent 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 start information +
Data of 29 persons + error + frame end information) is sent to the communication line.

(B) The execution completion data is received from the position controller 17i, and the position controller 17i is received.
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 being performed in a proper manner, the time over of the sampling timer is waited for, and when the sampling timer is 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 in the cycle 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 of the reink head can still be adjusted by adjusting the position of the balance weight. Therefore, the processing is executed in the same manner as in (B) above, but when both the position controllers 17i and 17j send inexecutable data, the balance adjustment of the reink head is performed by adjusting the position of the balance weight. Since the limit has been reached, the balance controller 29 sends the destination data and "error" data indicating the position controllers 17i and 17j to the raying head control board. The raying head control panel has an "error" display on its display panel (not shown) and the position controllers 17i and 17j of the error.
The information (No.) that identifies the item is displayed. After that, the balance controller 29 does not restart the above (A) until the control on instruction is given from the raying head control panel.
When the control-on instruction is given, the process proceeds to (A) above.

By the control operation of the balance controller 29 and the position controllers 17A to 17D described above, the rotation angle 36 about the rotation axis 1 of the raying head is obtained.
When the homogeneity of the weight distribution at 0 degrees collapses and the rotational shake of the face plate 5 exceeds the threshold value, the balance weight at the position that swings away from the rotary shaft 1 automatically moves to the inner side (direction closer to the rotary shaft 1). ), And the balance weight on the opposite side of the position around the rotary shaft 1 is driven outward (in the direction away from the rotary shaft 1), whereby the weight distribution around the rotary shaft 1 becomes more uniform, and the face plate The rotational shake of 5 becomes small. The abrasion of the J pipe 6 and the S pipe due to rubbing with the wire rod locally progresses, and the weight distribution becomes unbalanced. Along with this, the balance weight at the position (angle) where the weight decreases decreases in the radial direction. Driven to the outside, increase in rotational shake of the face plate 5 is automatically suppressed. Therefore, the face plate 5 can be rotationally driven at high speed. That is, the transfer speed of the wire can be increased.

[0035]

As described above, according to the present invention, since the imbalance of the weight distribution in the circumferential direction of the laying head with respect to the center of rotation can be compensated by adjusting the position of the balance weight, it is possible to increase the transfer speed of the wire.
