Spiral band spoke

The invention relates to a spiral strip store for continuously supplying a pipe train with strip. At Pipe lines are still mainly belt loop systems used, although these are extremely complex in terms of design and construction.

The previously known spiral tape recorders only work to a limited extent and are unsuitable for many possible uses. 'iDieWfoiiigel should by the device according to the invention be eliminated.

A spiral belt storage device has an outer winding collar with a concentric, small winding collar, the storage capacity being dependent on the difference in diameter and the number of turns. The formation of the outer wound collar takes place with the currently known Spiral ribbon spears either by feeding in from the outside on a rotating platform or, if the accumulator is inclined, on a roller ring.

In the currently known spiral band storage system with a platform, the problem arises that the large ring wants to enlarge to the outside when winding. In order to keep the outer diameter of the large ring constant, point the conventional belt storage with rotating platform has a wooden wreath, which also delimits the outside represents and slows down the outer turns. This creates between the platform and the belt edges Differential movements that are greatest on the outer layers and smallest on the inner layers, so that the surface the tape is damaged.

The memory with an inclined winding axis, on the other hand, is only suitable for small bandwidths for structural reasons

■ applicable. In addition, the dead weight of the wrap-around collar is a hindrance the contraction of the same, as is necessary in this system in the case of removal. Hence step surface damage to the belt in these stores too on.

To loosen a tightly wound collar into an open collar with distanced turns for the purpose of annealing or pickling the ribbon, it has already been proposed to mount the collar on conical support rollers, the diameter of which increases from the center of the collar outwards. HIE {\ is rewound on the tape recorded on an inner mandrel to the exterior. Such an arrangement is not suitable for storage operation, since in such an arrangement the tape must be transported from the outside to the inside.

In contrast to this, the invention relates to a spiral belt store for the continuous supply of strip material to eirve pipe, profile or carrier line, the store intermittently running the strip from a reel and the transport of the strip from an outer large ring to an inner small ring. According to the invention this is first achieved in that the large ring runs in a manner known per se on driven support rollers by which it is set in rotation. The support rollers can be designed to enlarge slightly conically in the direction of the center of the store.

It is already known in the case of spiral tape storage systems, the outer limit of the windings lying next to one another occasionally to be effected by an external roller ring. According to the invention on the other hand, the large ring is centered by external guide rollers that are in constant contact with it.

In contrast to the known external arrangement of the drive wheels, finally, the object of the invention is that the support rollers are driven via an internal ring gear and conical rollers covered with rubber.

In the drawing, an example embodiment of the subject matter of the invention is shown and that shows

Figure 3 illustrates a top view of the memory. Fig.3 is
a section along line AB of Fig.2. From the larger
The top view according to FIG. 4, drawn to scale, is the function
of the memory.

The tape a passes over the drive rollers 1 on the

twelve horizontal, driven support rollers 2 are mounted. ) ■

On these, the large ring G is made from band a in several
Layers formed which have a total thickness b. Of the
Uroßring is bordered outwardly by vertical loading rollers 7 ¹ I, which are not shown in Fig.l. On the radial

Between the lower edge of the large ring G and the support rollers 2 * V there is no differential movement at all, while between

The frictional forces between the individual belt windings are:

• very little here. These can also be reduced by moving the support rollers 2 against the center,
of the memory runs slightly conically enlarging.

From the large ring G, the band goes to the small ring K,

rolls, of which six in FIG. 2 and four in FIG

are shown. The small ring is hereby made by

The band a finally occurs at the pipe line speed VH over an inclined pull-out roller IO from the Kleinring K.

Before the store is put into operation, the large ring is wound with the required number of turns and the beginning of the strip is then introduced into the pipe train via rollers 8 and 10. Removes the Rohrstrasse tape from the Memory, so the small ring rotates in the direction of tape removal.

In llohrstrasse operation, a distinction must now be made between two further operating cases:

I. When the band preparation is ready, then the large ring is also G. liiebei moves between the large ring and Small ring K lying band in the opposite direction to the direction of rotation of the small ring, whey the band from the large ring wound onto the small ring.

II. In the case of feed-in operation with simultaneous pipe line operation, after the strips have been welded together started with the feed and the large ring G is set in rotation by "the driven cylindrical rollers 2". Care must be taken that the large ring does not rotate faster than the small ring K, otherwise it will rotate a loop would result.

The defects occurring in the platform arrangement, namely differential movement between the underside of the large ring and the platform, do not occur in the arrangement in question with cylindrical rollers, on the contrary, the individual tape layers get a speed that The feed axis speed and the peripheral speed of the cylindrical rollers are the same.
