DE1527788C - Three-roller driving device, which is arranged in front of a reel for strip-shaped rolled material - Google Patents

Description

here. As a result, very high tensile forces are applied with a relatively low specific surface loading guaranteed.

The three rollers of the driving apparatus are driven individually, with the drive power being the rear Top roller 7 is less than that of the other two rollers.

In FIG. 2 is the inlet position and in FIG. 3 the passage position of the invention Three-roller propulsion apparatus shown. The pass-through position is achieved when the coupling rod 8 raised by simultaneous extension of the piston-cylinder gear 9 and 10 parallel to itself will. It is essential that the guide table 15 is raised so that the tape is in front the roll 5 can not accumulate downwards.

Accordingly, the piston-cylinder gear 16 of the guide table 15 is controlled so that when the Roller 6 is raised, at the same time the guide table 15 is raised.

The in the F i g. The inlet position shown in FIG. 2 can be derived from the position according to FIG. 3 achieve by only the piston-cylinder gear 10 is acted upon in the lowering direction of the coupling rod 8, while the piston-cylinder gear 9 its extended

ίο Maintains position. According to the geometric The principle of rays also lowers the roller 6 so far that it reaches the inlet position according to FIG. 2 occupies, in which it together with the guide table 15 and the guide element at 17 for the proper threading of a new piece of rolled strip between the rollers 7 and 5 ensures.

In this case, however, the other strip-shaped rolling stock and the top roll directed towards this 5 are in accordance with the theorem of rays of the geo-guide means for the incoming strip end. metry is also lowered, so far that it is in front of it, in which two of the driven ones lie on one side of the belt together with one of the usual rollers in their area and a common carrier and one engaging table on it via guides arranged below the rolling stock path Infeed funnel through which the front piston-cylinder gear is inserted in the height position at the other end of the new piece of material to be rolled between the changeable and thereby different distances between the lower roller and the rear upper roller, from the opposite drive roller, from where the front end via another are blinding, characterized in that the guide table enters the reel,

Exercising a sufficiently high tensile force 20 guarantee. For thinner rolled stock, where the bending work is less important, this is also the case the end of the coupling rod facing away from the reel lowered and thereby also the roller aisle-side upper roller engaged or in contact with the lower roller 25 brought. The third position of the three-roller driving apparatus according to the invention is thus set. This The invention relates to a three-roller driving apparatus position corresponds to the normal working position advice, a coiler for strip-shaped rolled material and during the coiler. to this directed guide means for the one An embodiment of the invention is in Figu- running tape end is upstream, in which two of the 30 ren shown and will be explained below.

While the sub-role 5 statiogangs can be achieved. On the other hand, it is not possible to arrange the top rollers 6 and 7 in to bring about a run-in position of the rollers in which the 45 vertical plane can be adjusted.

The leadership of the band 1 is used a lifting and To solve this problem, according to the invention, a lowerable guide table 15, to which a piston cylinder is proposed, that the carrier above the belt of the gear 16 is assigned. Further conventional guides are arranged and a guide device receiving the roller axles is located above the coupling rod, which is connected at its ends to one of the lower rollers 5 in the upper of the piston-cylinder gears that are engaged by the piston-cylinder gears 6 and 7 left free Space 17 and for tanning and independently of one another force-impinging on those behind the lower roller 5 around 18. Said guide is firmly connected to the coupling rod 8. The arrangement of the two according to the invention is connected. Finally, in the area of the reel 4, jointly adjustable, upper rollers of the three-roller. another pulley 19 is shown,
systems has the advantage that, with little effort, the normal working position of the various positions of the three-roller system is shown in the three-line driving apparatus. How can be created. This results in the throughput, which is evident from the pulling force exerted by the three individually driven positions for the rolling stock when the two upper 65 level rollers of the driving apparatus roll onto the strip 1 by lifting the coupling rod parallel to the tensile force exerted between them even from the lower roll simultaneously removed the upper rolls and the lower roll and from the banding. Loops on the upper roll 6 and the lower roll 5 for threading a new piece of material to be rolled
