Description

Roll-up device for paper or similar webs lead most of the time @Paper processing cliinen @it is required without stopping the machine may be 'to change roles. It now depends on the Ganges of the machine to take out the fully wound paper roll or the like and insert a new winding mandrel for winding the next roll without; d, ate too much loss of work material occurs here, the work process must accordingly very quickly; go, therefore, depends on the skill of the person carrying out the work Labor dependent. Nevertheless, it cannot be avoided that when changing roles always a certain amount of the finished paper or the like becomes unusable.

The thought now arose of changing roles in order to gain time to dismantle in two stages.

One has z. B. Rollers designed as so-called. Double roller and either both support rollers, or only the foremost one on the one facing the viewer Provided the side with its swiveling mandrel holder.

Finally, you have Aufrollvorridlitungen with three driven support rollers suggested. While: the big roll is still running on the two main support rollers, is placed between the middle support roller and a third support roller, the so-called. Feed roller, a .new winding mandrel put on, to @dean then while pulling up between the finished wound roll the paper web coming from the unwind the first and the middle roller, touching them, comes to the reel of is turned backwards. The winding mandrel is also driven by the driven forward feed driven, with the accumulates paper rolls up. After removal of the finished roll, the beer becomes Winding mandrel by swiveling the holder into the working position, d. H. brought between the main support rollers.

With the just described 'arrangement of the individual support rollers: is the roll-up process or the roll change, how nice-. mentioned in two Work stages broken down by creating two. Roll-up stations. Nevertheless that is enough here. Time savings achieved especially with fast running machines not to the. Loss of at least a noticeable amount of what has to be rolled up To prevent material when changing rolls.

The object of the invention, which is intended to avoid these disadvantages, is now that with such Aufrollvorrichtüngen with three support rollers the first support roller an additional mandrel holder is arranged such that it can be pivoted is that the roll forming on the first support roller is applied to the first and second Carrying roller can be pivoted in order to be kept in operation there, before moving onto the second and third carrier roller after the finished roll has been removed is swiveled.

When the subject of the invention is therefore the paper web on the .first support roller out, so not as in the known device between = the = second and third support roller.

Due to this paper guide and the resulting larger distance between the winding mandrel on the first support roller and the lower support roller it is possible to maintain the freedom of movement required for the work in question.

In the known device it is according to the described arrangement the winding mandrel between the first and middle carrier roller difficult to separate - the web -urid, -to accomplish the application of the beginning of the web to the new winding mandrel, there. the distance between the winding mandrel and the main support rollers. for the execution of the said two work stages is much too short.

The type of paper guide, the position of the winding mandrel and the large one Distance from the winding mandrel to the second support roller, which is a better option : for- the paper web separation -and- the application to the .winding mandrel results, - are but the most important basics for a flawless practical work of the Contraption. A winding mandrel can also be used with the subject matter of the invention the first support roller, are placed, - while between, the first and -the '.middle carrier roller still has a second mandrel in the. Winding is located. A. : third The winding mandrel with the _full @ roll can still be on both of them at the same time Main carrier rollers are running. - This also results in a decidedly better utilization of the individual time periods when changing roles, since the -new device over @JJei has rolling stations, while the loading, z bkän-nte device, as mentioned, only has two. .

The effect of the winding device according to the invention is from the Fig. I to 3 of the drawing can be seen.

The - from the not signed paper, paper processing or A paper web or the like coming from a machine of a similar type overflows as shown in Fig. i the diverting rollers b1, b2 and b3 under the main support rollers driven at c, d and e or under the main support roller e driven at f and the Vorragwalz.e b through, around the presentation weigher g, on the main support rollers e and touching them, over to the roll ft. The replacement winding mandrel i is placed on the through the swiveling Winding thorn holder k created Vorrollstellle placed and rolls empty on the .below a sliding paper stick. When the roll ° h has reached its maximum diameter, so the paper web a is separated and the The beginning of the paper, as shown in dashed lines at a, wrapped around the replacement winding mandrel i. During this time, the roll h can continue to run quietly while at the pre-roll position on the replacement winding mandrel the reeling continues uninterrupted.

Then the swiveling mandrel holder k, as shown in FIG Fig. 2 can be seen, brought from position k to position k1. This will , the mandrel! without interrupting the winding process forwards into the position il, d. H. between the main support roller e and the feed roller j, pivoted. .

In this working position, the winding can up to the winding mandrel to a certain diameter. During this time. is it possible how indicated in the drawing Fig.2, the fully wound roll h after. up or sideways to remove from the retractor.

If the fully wound roll is removed, the two main support rollers d and e have become free. The roll Ir located in the winding on the winding mandrel i or il is now, as can finally be seen in Fig. 3, transported by means of the pivoting mandrel holder m to position ml between the main support rollers d and e. In this position - the roll can be wound further up to the desired diameter.

Otherwise, the same designation as -die applies to Figs. 2 and 3 .the Fig.-i. The direction of rotation of the individual rollers is indicated by the direction of the arrow : specified.

Claims (1)

PATENT CLAIM: Roll-up device for paper or similar webs with three support rollers driven in the same direction, of which the ferste is intended to initiate the rolling process, while the other two n, ad'h pivoting the emerging role on this End the rolling process, characterized in that an additional mandrel holder (k) is pivotably arranged around the first support roller (g) in such a way that the roll forming on the first support roller (g) on the first and second support roller (g, e ) can be pivoted in order to be kept in operation there before it is pivoted onto the second 'and third support roller (e, d) after the finished roll has been removed.
