Storage device for foils

The invention relates to a device for the rapid stacking of individual items produced by pre-folding Sections of a tape, in particular on paper storage devices on printers.

In the case of high-speed printing devices, for example tabulating machines, which are used as output devices for electronic computing devices Are used, it can usually be observed that under the debris hitting the stack

cut the pre-folded paper web initially forms an air cushion, which can easily lead to disruptions, in particular to curl an edge of this section. The air cushion is even capable of storing containers that are open at the side often does not escape quickly enough, especially when using paper types with a low specific weight, especially single-ply papers.

The invention is therefore based on the task of finding a way to remedy this evil.

The device according to the invention for the stack-like depositing of pre-folding sections of a The tape is characterized by suction means arranged next to the depositing point, through which the formation of a Air cushion under each newly hitting tape section this prevents suction means from being applied to the end face of a band section produced by pre-folding forming stack are arranged.

The invention is explained in more detail below with reference to figures and an embodiment shown therein.

The figures represent in detail:

Figure 1 shows the phenomenon which can be observed in the conventional storage devices as a rule is;

Figures 3 and 4 show a front or side view of an inventive Filing device.

As already stated at the beginning, forms in conventional Storage facilities, especially when using light types of paper, in the manner shown in Figure 1 below the last a sheet or section of tape that has hit the stack Cushion of air that normally escapes slowly, making it easy for an edge of this flat or Section come. With the invention, however, it is possible to break down such an air cushion very quickly, or already to prevent its formation, so that the individual sections are properly stored in the manner shown in Figure / 2.

In FIGS. 3 and 4, a carriage 1 is shown as it is used for receiving the stack of paper on both the feed and storage sides. a high-speed printer or the like. Use. On the carriage 1 means are arranged in the form of rods 2 to the individual sections of the paper web 3 formed by pre-folding in an orderly manner, d. H. in the form of a stack 4,. to bring to the shelf. To the side of the stack 4 is üfoi low A suction unit 5 is arranged at a distance from this, through which, according to the invention, the air cushion which is otherwise formed according to FIG. 1

is quickly suctioned off. -

The suction unit 5 consists, for example, of a single ... Fan. In order to achieve a more even suction effect on as large a part of the end face of the stack 4 as possible, However, it may be advisable to arrange several such fans next to and / or on top of one another. Suitable for this Especially the commercially available, very flat external rotor fans using induction motors. One Such an embodiment is particularly recommended when only a small amount of space is available for the suction device stands.

An even more even effect can, however, be achieved - provided that the space requirement allows this to be achieved with suction units 5 of the type shown in FIGS. With these is a fan 6 with a funnel 7 in front of it is arranged on a stand 8. In the simplest case, the bracket 8 is simply open put the car 2, it is expediently equipped with rubber feet as anti-skid.

In the example shown, however, the stand 8 is on the carriage 1 fastened by screwing. If paper webs of different widths are to be used, there is an easy-to-use one Adjustment for the bracket 8 is that wing screws 9 are provided to fix it, the Sdhraubbolzen

To achieve a more even suction effect, especially with a very flat one; Funnel 7, as it will usually / use for reasons of space, it may be advisable to use a throttle grille on the side facing the stack 4, for example in the form of one provided with openings. Plate 11, to cover. Such a cover can also serve as a guide for the paper web 3 in order to prevent parts of the same from being torn into the fan 6.
