Abstract

PURPOSE:To prevent forgetting of setting through automation of setting of primary diameter, by a method wherein ultrasonic distance measuring devices are mounted to a turret shaft so that they are positioned at right angles with an unwinding shaft, and a signal fetched through a slip spring is utilized as a primary signal. CONSTITUTION:Ultrasonic distance measuring devices 30 are mounted on a turret shaft 40 so that they are respectively directed at right angles with the cores of shafts A and B, and signals therefrom are fetched through a slip spring 31 to the outside. The outputs of the measuring devices 30 are inputted as the primary diameter setting signal of a winding diameter detecting circuit 18. The primary signal generates a one shot signal in linkage with the chucking instruction of a chucking device mechanically formed to aid in engaging and disengaging of an object 11a to be unwound with and from the shaft A, and a primary diameter is set by means of the one shot signal. This eliminates troublesome operations to set primary condition each time an object to be detected is replaced, and location of measuring position on the turret shaft permits normal detection of a reliable diameter irrespective of position of the turret.

Description

[Detailed Description of the Invention] (a+ Technical Field Description) is an improved tar 1 that automates initial diameter setting.
．． - Relating to a screw type center 111111 drive unwinding device.

(1)) Description of Prior Art FIG. 1 shows a conventional turret type central shaft unwinding device. In the figure, it is a 241111 turret type unwinding machine, and the unwinding proboscis 11a and llb are respectively attached to two shafts A and 13+Il+. Also, in the figure, only the drive device for the A-axis is shown for convenience, but the drive device 1 for 13ii'llll is also the same! , is equipped with.

The material to be unwound 11a is driven by a direct current '1' pulsating force 12 so that the surface speed of the diameter matches the line speed. The rotational speed of the DC electric motor 412, i.e., the rotational speed of the central part of the material to be unrolled, is detected by a tachometer 13.

In order to control the rotational speed of the DC motor 12, first, the line speed reference signal 22 and the surface speed of the material to be unwound 11a are matched at the speed 11ifl + wholesale amplifier 17 C3.
The iL1 error is amplified to obtain a mixed current reference signal. Then, this ′
1 and 1 in the amplifier 16, and the error amplified signal is sent to the phase control circuit #! Manpower to 115. As a result, the phase tljlJ r+11 circuit 15 becomes gate 1.
Output the n number and set the firing phase of Cy922140 to 1lilJ
(Ill,, set the DC output Fit pressure to 0T and run 120 rotations of the DC current for 1 hour so that the surface speed of the unrolled material hits the line speed.

On the other hand, for surface speed conversion No. 81M, the winding diameter protrusion + ul path 18
Multiply the winding diameter No. 18 IJ of the nine-wave unrolled object detected by the tachometer I3 and the rotational speed n of the central axis of the unwound object detected by the tachometer I3, and calculate it by 44''9 to convert it to the surface speed. value 24
(v==I)x n ) is obtained. Therefore, the operation of the winding diameter detection circuit 18 is to compare the line speed system input signal -Q' 22 with the surface speed 1/2 conversion value 24, and find the R'l difference as S11.
By changing the winding diameter signal output 1 until the line speed and wave ejected material display speed (n×l)) are equal to j and f. This conclusion Song, vol.
Warts are always detected) 1. This means that

In addition, the winding diameter detection circuit r() field is used to set the winding diameter of the material to be unwound in advance.
In order to prevent this, an adjustment resistor is provided. If this initial diameter setting is neglected, the difference between the line speed standard and the surface speed conversion value will be larger than f at the beginning of operation, resulting in a null of unwinding and the like.

(C) Problems with the prior art However, when the winding diameter detection power I is large with tS,
When the proboscis is special and replaced with the next core, it must be 4
``There is a necessity to perform the Hatsumei 1st setting, and the unrolled product r)J
, when the cutting diameter' is not constant, the working sound has to be set one by one, making it sound like a grinding operation. If you forget to set the initial setting, the unrolled material will run out of control and be dangerous to the operator, and furthermore, the unrolled material will be unnecessarily discharged, resulting in loss. .

(d) Object of the Invention The present invention is described in Section 2. A turret-type center shaft that was created in consideration of the current situation and has no drawbacks mentioned above, which makes the 0 stage diameter setting more dynamic and prevents forgetting the initial diameter setting! It is [1 purpose] to provide a 118.1b unwinding p7 position.
