Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous monitoring device for the winding cut surface and winding surface of a surface winder, and more particularly to a continuous monitoring device for a surface winder for winding products in a paper manufacturing plant.

Generally, in a paper manufacturing plant, a spool is wound onto a spool from a paper machine and then re-wound with a wine gourd to create a product spool. As for wine goo, the product winding that is rolled up by wine goo is generally placed on the wine goo's drum roll, and the rotation of the drum roll causes the product to be rolled up by the wine goo. A surface winder is often used in which the product rolls up while rotating.

In the above-mentioned surface winder, winding abnormalities such as lower winding wrinkles, lower winding torsion, stitching, and flower shapes may occur during winding rotation. In order to instantly confirm the occurrence of such a winding abnormality, it is necessary to continuously monitor the winding surface or winding cut surface during winding rotation. However, if the wine goo is a high-speed aircraft, the speed is about 2300 rn/mi.
n, it is difficult to be monitored by the human eye. Therefore, in order to continuously monitor the winding surface or winding cut surface during rotation, there is a method of manually tracking the entire emission frequency of the stroboscope so as to synchronize with the rotation speed, but the above winding abnormality , occurs most frequently in the lower winding immediately after the start of winding 9, and in that case, since the winding is continuous, the winding rotational speed changes extremely sharply and it is not easy to obtain the same V. Further, even when the drum roll is rotating at a constant rotation speed, the winding rotation speed changes due to a change in the winding diameter, so it is not easy to achieve complete synchronization.

The object of the present invention is to provide a device for detecting the winding diameter and winding speed in a surface winding machine and thereby generating a P pulse signal proportional to the winding rotation speed, thereby making it possible to create a general-purpose stroboscope! The object of the present invention is to emit light in synchronization with the number of revolutions, thereby making it possible to detect defects appearing on the cut surface and surface of the rolled product at an early stage during the entire manufacturing process. A device that continuously monitors the winding cut surface and winding surface during winding rotation in a surface winder that rewinds and winds the taken paper as a product winding, the continuous monitoring device comprising: Calculate the rotation class of the winding using the winding diameter detection means that changes during the winding rotation, the winding speed detection means, and the output signals from the winding diameter detection means and the winding speed detection means. an oscillator that generates a pulse signal with a frequency corresponding to the output signal of the arithmetic unit;
and a strozescope that receives the pulse signal from the oscillator as an external synchronization signal.
There is provided a device for continuously monitoring the winding cut surface and winding surface of a surface winder, characterized in that the projector of the stroboscope illuminates the winding cut surface and the winding surface in synchronization with the rotation speed. Ru.

A winding cut surface and winding surface continuous monitoring device of a surface winder as an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a continuous monitoring device according to the present invention. FIG. 2 is a schematic diagram showing an example of a surface winder to which the monitoring device shown in FIG. 1 is applied. The monitoring device shown in FIG.
, winding speed detection means 12, winding 11y rotation speed calculator 13,
- Consists of a Pruss oscillator 14, a power supply, and a strozescope 15. As the means for detecting the winding diameter and winding speed in Table 1 J'lI winding, known means can be used as described later. In the controller 13, the rotation speed N=i is calculated using the winding diameter detection output and the winding speed detection output V. The thorax machine 13 outputs an output signal (for example, 1 to 5
V D C, )N is supplied to the excavator 14 . Oscillator] In 4, the oscillation frequency f is proportional to the winding rotation speed N.
Generate A'Rus Tsukuda with a stroboscope 1.
5 as an external synchronization signal.

The Strozescope 150 floodlight 15 & illuminates the winding from the direction of the winding shaft when the cut surface of the winding is to be seen, and from the side of the upper blade of the winding when monitoring the winding surface. The light is emitted in synchronization with the winding rotation speed.

Next, a case where the monitoring device shown in FIG. 1 is applied to the surface winder shown in FIG. 2 will be explained. Although a two-drum winder is shown in FIG. 2, the present invention can also be applied to other types of surface winders. In FIG. 2, the product winding 20 rests on the soil of a front drum 22 and a rear drum 21, and as the drums 21 and 22 rotate, the product winding 20 rotates and winds up the paper. The product winding 20 is pressed between the front drum 22 and the 1-north drum 21 from above by a rider roll 23. The vertical movement TrlIJk-1 of the rider roll 23 is converted into 240 rotations of the pulley.

The method for detecting the winding diameter of the surface winding of the second I is as follows:
Recently, a method of detection using k-r and pulse generators PL and G has been developed. That is, the diameter D of the winding core
o is the height II of the center of winding before the start of winding.

If the height of the center of the rider roll 23 during winding is L, then the winding diameter is given by: Here, L is no R)res generator P
The force is determined by the number of pulses P from LO. When formula (1) is rearranged using constant sounds determined by the winder specifications, C=2H, -D and d=B -Dd.

? The calculation for detecting the winding diameter from the rise of the rider roll described in TI is performed in the controller of recent winders, and when applying the monitoring device according to the present invention, it is sufficient to add an input/output crab unit. is. ′−
1: If this is insufficient, it is advisable to provide an arithmetic unit that can perform the above operations.

Detection of the winding speed in the surface winder of FIG. 2 can then be performed by means of a tachometer generator TGtiH pressure generator PLG mounted on the drum roll shaft.

FIG. 3 shows an example of changes in the winding speed and winding rotation speed immediately after the start of winding in the winder of FIG. 2. Third
In the illustrated example, the winding speed #V is a case where the winding is accelerated at a constant acceleration α immediately after the start of winding, and after reaching the constant speed, the winding is performed at a constant winding speed. Even in this case, the winding rotation speed N
changes non-linearly as shown in the figure. In addition to this example, when changing the acceleration α or when changing the winding speed υ, the winding rotation speed Nr also changes in a more complicated manner.

Ai A simple divider is sufficient as a calculator for calculating the winding rotation speed from the detection outputs of the winding diameter and winding speed mentioned above.If a programmable controller is provided, the program He is an executive director with just the additions and additions of incoming and outgoing crabs. A commercially available device can be used to generate a pulse frequency commensurate with the winding rotation speed from the output of the deducer. As the stroboscope, a general-purpose product with an external synchronization signal can be used. According to the test results, it is possible to confirm the lower volume by irradiating from a distance of 1 to zm.

According to the above-described continuous 18° viewing device according to the present invention, the rotational speed of the winding, which changes non-linearly, is detected and used as a synchronization signal for the light emission frequency of a general-purpose stroboscope, thereby adjusting the rotational speed. It is possible to constantly monitor the winding cut surface and winding surface in a stationary state regardless of changes, and the occurrence of product defects can be instantly discovered. Therefore, when a defective product occurs, the wire/gating can be stopped immediately, and it is possible to improve product yield, improve the quality of shipped products, and save labor. Furthermore, instead of human monitoring, if we could add an automatic detector with a function to recognize the occurrence of defective winding, it would be possible to develop automatic stoppage of the winder in the event of abnormal winding. be.

Further, the continuous monitoring device according to the present invention is not limited to paper manufacturing plants, but can also be applied to other industries where surface wrapping is performed (film processing, textile or non-woven fabric industries, etc.).
