MAGAZINE FOR STACKING ITEMS

The present invention relates to a magazine for stacking objects from the magazine individually for further processing should be accepted.

In the paper processing industry one often has to deal with objects that are slightly wedge-shaped, e.g. folded greeting cards, even small blocks with a binding margin. the The wedge shape of each individual item, e.g. folding cards made of cardboard, is barely noticeable. In contrast, a stack of 20 such folding cards already have a noticeable wedge shape. Even 40 folding cards with the fold on the same side do not remain lie more on top of each other by themselves. The top ones slide off.

There is a need to individually remove such slightly wedge-shaped objects from a magazine for further processing refer to. The objects can, for example, be punched, glued, individually packaged or, in exceptional cases, printed.

If folding cards or other slightly wedge-shaped objects are placed in a vertical magazine, the result is an arrangement according to FIG. 4. From the first pack 2, the uppermost folding card 1 is already touching one guide side 5 of the magazine 7. Further folding cards placed on top then assume the arrangement in the pack 9, for example. This representation may be exaggerated, but it shows the problems with stacking and unloading such items. The same applies to horizontally or inclined magazines.

The use of arcuate magazines could make the stacking of wedge-shaped objects easier; however that would be Because of the wedge shape, the radius of curvature is so small that you can only could accommodate little folding cards in such a magazine. In addition, the radius of curvature would have to be on the respective Wedge shape of the objects are coordinated, which causes difficulties when, for example, folding cards of different widths (This means the dimension across the folding edge) should.

The present invention aims to create a magazine that allows for proper stacking of wedge-shaped objects enables. The invention has preferred application in straight magazines, regardless of whether they are horizontal or plumb or are arranged obliquely, but can also be curved Apply magazines.

The stated object is achieved by the invention according to claim 1. (The following is based on the wording of the claims Referenced).

Narrow the inclined surfaces that follow one another like scales in each case the guide shaft of the magazine to a dimension that is smaller than the decisive dimension of the wedge-shaped Objects. This is the dimension, e.g. at right angles to a folding edge, i.e. the dimension in the direction of the wedge. This dimension is called the "wedge length" in the following. As a result of the narrowing, the thin edges of the Objects held up by the inclined surfaces so that the objects are to be stacked in an orderly manner. When emptying of the magazine, the thick sides of the objects slide first against the removal side, so that the objects slightly Tilt until the thin sides slide over the respective inclined surfaces.

Further advantages of the invention are given in the description of the figures explained.

Developments of the invention

According to claim 2, the inclined surfaces can be at least two Guide rods or the like. Be provided, which are arranged on the same guide side side by side, while the opposite guide surface is smooth. This arrangement is useful for upright folding cards that have a fold on one of their long sides.

In this arrangement, the angle of the inclined surfaces can be the same as in Claim 3 have specified values.

A different arrangement of the inclined surfaces can then be advantageous if you want to stack wide-format folding cards, and although those that only have a narrow folding edge, i.e. height and, in contrast, a large width. Then the bevels can according to claim 4 on opposite guide sides be arranged, in the vicinity of the a guide surface of the magazine running transversely to this.

Since in this case inclined surfaces face each other or are essentially opposite, it is expedient to use half-size bevel angles in comparison to the arrangement described above.

In the following, the invention is based on further features the drawing explained in more detail.

Figure 1 is a vertical section through a magazine according to Invention with inclined surfaces only on its one guide side .

Figure 2 is a cross section through this magazine.

Figure 3 is a cross section through a modified embodiment of the invention with opposing guide rods with inclined surfaces.

Figure 4 is a longitudinal section through a conventional magazine with flat guide surfaces and shows in which undesired Arrange wedge-shaped objects in it without special measures.

The magazine 7 according to FIGS. 1 and 2 has opposite one another Guide pages 10 and 11 on the one hand and 14 and 15 on the other. It is used to stack items 1, namely Folding cards, the folding edges 3 of which are on the left-hand side of the magazine in FIG. 1. The guide surfaces 10, 14 and 15 of the magazine are smooth and are formed by angled guide rails 20. On the guide side 11, the Magazine two guide rods 22. Each of the guide rods has obliquely arranged guide surfaces (inclined surfaces 24). the Inclined surfaces 24 are arranged one above the other in a scale-like manner that they face the opposite guide side 10 approach in the conveying direction (arrow 26). The horizontal distance between the guide side 10 and the upper end 24.ο of the inclined surfaces is equal to the wedge length of the folding cards (i.e. in this case in the width of the folding cards that can be seen in FIG. 1 from the folding edge 3 to the opposite one Page). The distance from the guide side 10 to the lower end 24.u the sloping surfaces is considerably smaller than the wedge length.

The angle ß that the inclined surfaces 24 with the longitudinal direction of the guide rods 22, i.e. enclose with the guide surface 11, is preferably 20 degrees. Also values between 10 and 30 degrees are applicable. The specified values apply to cardboard. In the case of objects made of other materials suitable angles can be determined.

As usual, the magazine has a base plate 26 and a suction tong feeder 28 for removing individual cards and for placing them on the subsequent processing device.

When the folding cards are stacked, their right, thin edges are prevented from slipping off by the inclined surfaces 24. So it is provided for vertical gaps between the objects or folding cards on the right guide side 11 and thus prevents packing after a shape Figure 4 form.

When the magazine is in operation, the inclined surfaces ensure that first the thick edges of the objects, here the folded edges 3 slide down a little before their opposite thin edges slide down.

The inclined surfaces ensure both when stacking the Objects in the magazine as well as during ongoing removal from the magazine for an arrangement in which the damagingly large Tilt angles of the individual objects can be avoided.

In addition, the objects are opposed by the inclined surfaces pressed the opposite wall. The objects thus have friction on the inclined surfaces and the opposite one Leading side. This prevents a heavy collapse of a stack or damage or jamming of the lowest objects. The pressure on the lowest object is lower than that of a normal vertical one Magazine. This is desirable because you then have to deal with relatively high

Magazines that can only work in appropriately longer lengths Must be refilled at intervals. But this is desirable in the interests of efficient production.

Figure 3 shows a modified embodiment that is suitable Idt for objects whose wedge length is particularly large compared to their dimensions at right angles, e.g. folding cards with a very short folding edge. The the guide rods 22.1 carrying the inclined surfaces are arranged on the mutually opposite guide sides IA and 15, namely in the vicinity of the guide side 11. In this case have the angles ß, which the inclined surfaces enclose with the guide surfaces, i.e. the conveying direction, are equal to the embodiment of Figures 1 and 2, only half size.

If the invention is applied to arcuate magazines, so are the guide rods with sloping surfaces on the a cylindrical guide surface on that with the smaller radius.
