Description

[Detailed Description of the Invention] (Industrial Application Field) In this B-light, a metal strip (hereinafter referred to as a strip) is trimmed with a site 1 to 111 trimmer, and then tension is applied in the direction (J 'j L). In the strip processing line where the strip passes through the heating furnace and is processed, the temperature of the strip in the heating furnace is the highest (1 line fJ near C, sensor 1 no detects the inside of the strip and 1 hemming Ill is WJ

Concerning the key flii%r.

(Prior art) In the above-mentioned type of slip processing line, (

It is common to rim 1 to 1 ntI L/middle, but according to this method, the temperature of the strip in the heating furnace y7 and the tension J applied to the strip are It is necessary to adjust the head of the rimming knife by taking into account the reduction in size, and the operator often relies on his/her experience with the shuttle and intuition, resulting in a lack of accuracy. Moreover, fluctuations in the tension of the strip in the heating furnace,
If the conditions of the preheating section 49 and the heating section C until the strip reaches its maximum temperature change, the shrinkage of the strip will also change.Therefore, the product may not be able to maintain the required width of C, and there is a risk of producing defective parts. In addition, the coil 11 of the processed strip wound product varies and is not consistent, or the processed strip is cut into constant lengths and sheared sheets are piled. There were problems such as unevenness caused by the piping, I4J/I warping due to threading with the side guide in the pile ring, and wear on the guide surface.

(Object of the invention) This defense is made in view of the above points.
By measuring the width of the strip near the maximum temperature of the C strip in the heating furnace under the given conditions and adjusting the knife position of the C side trimmer, the minimum width required for the product can be secured, and the width of the strip can be adjusted. It is an object of the present invention to provide a strip side trimming IJ adjustment device that allows adjustment work to be performed easily and accurately without having to consider temperature rise or applied tension.

(Structure of the Invention) This invention provides a metal typeface processing line in which the metal typeface is mid-trimmed with a side trimmer and then passed through a heating furnace while applying tension in the longitudinal direction. A sensor for detecting the width of the metal strip passing through the heating furnace is installed at the highest position near the top, and the position of the trimming knife of the side trimmer is adjusted based on the detection value of the sensor. 1.
The gist of this is the adjustable stomach filling.

Hereinafter, embodiments of the present invention will be explained based on the drawings.

Figure 1 shows a strip processing line, in which the strip A is side trimmed by a side trimmer 1, and then transferred to the furnace through a strip storage mechanism 2 that keeps the conveying speed of the strip A constant at a constant speed. The strip A is fed into the heating furnace 3 and tension is applied to the strip A by tension rollers 4 disposed near the entrance and exit of the heating furnace 3, respectively.

5 is a section 3' that heats the strip A placed in the front part of the heating furnace 3 (see-through window e1) to the lowest temperature.
A gap 1] is formed in one or several places on the ceiling wall of the furnace, and heat-resistant glass is fitted into this gap. 6 is heating furnace 3
A sensor that detects the width of the stritz °Δ passing through the
As shown in FIG.

Figures 3 a3 and 4 show the details of the guide tray 7-1, in which a pair of knives 7.8 are arranged on both sides of the strip △ so as to sandwich the strip A, and each knife 7.8 are installed at θ° on both sides in the feeding direction of the strip A as shown in FIG.
The trimming II] can be adjusted by moving each knife 7.8 through C. still,
! In Fig. 14, the knife 7.8 is configured to open θ° to both sides in the feeding direction of the strip A, but it is also possible to rotate the knife 7.8 with a radius r around point B, or C. Alternatively, the knife position may be changed by moving the knife 7.8 along the center line C along the line Iij as shown in FIG.

In J3, Figure 3, 11 is the knife drive IF! 12 is a knife position detector, 13 is a product 11'' setting device, 14 is a line position command device, 15 is a comparator, +61. Expected shrinkage + 1 Jα that L strip A shrinks while it passes from the rr1 high hot water 1f 1/neck of the strip Δ in the heating furnace 3 to the furnace outlet and becomes a product: It is a stacking command device.

Next, the manner of adjusting the side 1 to rim 11 of the C strip in the above embodiment will be explained. In Figure 3, there is J3,
Set the bean paste in the product in advance to the setting device 13 (Product 11) J3

The value 1-+α, which is the set value of 3 and exceeds α during expected reduction, is commanded to the drive command device 11, and further, the knife drive mechanism 9.10 is operated by the command from the drive command device 11, and the knife 7 is

When the fiJ command value of the command unit 14 becomes difficult, the command is set to 117, and the adjustment at the 8th position is set to f'.
l-Millet ends.

In these four positions, the reid of S1 helitube Δ is J to 7-'1.
After the trimming is done, the strip Δ is sent to the strip storage machine (I42) and heated 1313 for processing.

When this J is sent to the heating furnace 3 through the lip Δ to the rimmed strip 1, the lens 61JJ detects the stiffness of the strip passing through the heating furnace 3. The detected value 1-' is sent to the comparator 15 and 1iiJ
At times, this comparator 15/\command value from the command unit 14 (
-1-α is sent and the 1+0 of both ministries are compared, and then the comparison difference B at - is hacked to the top controller 16, but if there is no comparison difference β, the top controller 1G is transferred to the controller 1.
The command to the drive command unit 11 from the command unit 14 remains in a state where the command from the command unit 14 to the drive command unit 11 is stopped.

However, if the comparison difference β occurs, the above Wiα is corrected by C by the comparator β, and the command unit 14 is again commanded with the offset value α±β of −11, which is then passed through the drive command unit 11 to the (149, 10 are operated (knife 7.8 position adjustment work is performed).

(d) When the Hinley 6 is inserted into a plurality of 112.1 stages, the detection value detected in the small strip of +;L, fft is prioritized (sent to the comparator 15/\).

(Functions, Effects) As explained above, this invention has a hinge (J) for detecting the width of 1 nod of the strip passing through the furnace near the position f=J where the temperature of the strip of the heating furnace is the highest. - is installed, and the position of the trimming knife is adjusted based on the sensor of the sensor, so the difference between the detected value of the strip and the actual product does not occur frequently, and the conventional side 1
