Abstract

PURPOSE:To prevent damage of a coil and a peripheral mechanism, by providing a small roll group and a supporting part for supporting this group on a coil for winding a rolling steel sheet, so that spring-up of the tail end of a coil can be prevented. CONSTITUTION:A titled winder consists of a wrapper roll 4, an apron 6 for supporting the roll 4, a freely rotatable roll group 7, and a supporting part 8 which supports this roll group 7 and is installed to the apron 6. Said roll 4 presses a coil 1, etc. fed by a pinch roll 3 against a mandrel 2 side in order to wind them around the mandrel 2. Also, the roll group 7 is movable independently of the roll 4 and the apron 6, and presses the tail end of the coil 1, etc. separately from the roll. According to said coiler, the tail end of the coil does not spring up, therefore, damage of the coil 1 and the peripheral mechanism is prevented.

Description

[Detailed Description of the Invention] (11M Description of the Technical Field The present invention relates to a winding WA (hereinafter referred to as a coiler) in steel rolling, and in particular a function to prevent the tail end of the coil from jumping up within the coiler. The present invention relates to a winding machine having a winding machine.

(b) Explanation of the prior art In No. 1 #A, the coil 1 is wound by the mandrel 2 due to the coiler general factor, but in order to wind the coil 1 first, the wrapper roll 4 and the apron 5 are used to properly wrap the coil 1. In addition to applying a strong pressing force, the direction of the tip is guided around the mandrel 2. Thereafter, the wrapper roll 4 and the apron 5 rise above the surface of the coil 1 until just before the end of winding, and the wrapper roll 4 presses down on the coil 1. However, the number of wrapper rolls 4 is usually 3 to 4, and as a result, the bottom end of the coil cannot be sufficiently pressed down, causing the tail end of the coil to jump up, damaging the coil or damaging surrounding mechanisms.

(cl) Object of the Invention The present invention was made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a winder having a function of preventing the tail end of the coil from jumping up within the coiler.

(d) Structure and operation of the invention An embodiment of the invention will be described below with reference to the drawings. Figure 2 is an enlarged view of Wrapper 4 and Apron 5 in Figure 18 (:).
! i! 6 and 7 of il are a new shaped apron and small roll group adopted in the present invention. 8 is a support section attached to the apron 6 that supports the small roll group.

Rate below 31S! This will be explained by ii.

13 E (a) is a top view of the equipment consisting of the 57/(-C7-ru 4, xy lower roll, support section 8, and small roll group 7. (a) A'
-A' arrow view is shown. That is, the mechanism for preventing the tail end of the coil l from jumping up is comprised of a small roll m7 provided to prevent the tail end of the coil l from jumping up, a support part 8 for supporting the small roll group 7, and an apron 6 shaped to accommodate these.

When winding up the coil 1, the wrapper roll 4 and the apron 6 contact the coil 1 to apply excessive pressure and guide the tip, as in the conventional case. After that, the coil 1 rises above the surface of the coil 1, and the coil 1 is moved up to 4! It's being taken away.

Next, when winding of the coil 1 is completed, the wrapper roll 4 and the apron 6 are stood up, and the small roll group 7 contacts the coil 1 to prevent the tail end of the coil 1 from jumping up.

Although the support part 8 that supports the small roll group 7 is not shown in this figure, it is driven by an air cylinder force.
Also, each roll itself is designed to absorb the shock when it comes into contact with the coil 1 using a spring or the like. Also, the timing at which small roll #7 is driven is different from that of mandrel 2 or the first roll.
PG (pulse oscillator) attached to Vinci Roll 3 in the figure
etc. will be implemented. By tracking the position of the tail end of the coil 1, it is possible to provide the optimum timing in relation to the driving time of the small roll group 7 and the winding completion time.

te+ Effects of the Invention As described above, according to the present invention, it is possible to prevent the tail end of the coil from jumping up inside the coiler at the end of winding, and as a result, damage to equipment can be reduced.

Incidentally, in the above embodiment, the thing to be wound was a coil, but
Of course, the present invention can also be applied to wire rods and the like.
