Abstract

The stacking board is designed as a stackable pallet (1) which exhibits on its underside, on opposite side borders (1a, 1b), in each case two hollow feet (2) and two hollow latching protuberances (4,5) with a smaller engagement depth than that of the feet. The feet on each longitudinal border of the pallet are located opposite the hollow latching protuberances on the other longitudinal border. When a number of pallets are stacked upon one another, depending on the orientation of the pallets, either a tightly packed storage stack is produced where the feet of the top pallet are sunk into the hollow feet of the lower pallet, or a working, spaced apart stack is produced where the feet of one pallet engage into the hollow latching protuberances of the pallet below.

Description

The invention relates to a stacking board for storing a stack of sheets, in particular one Stacks of note sheets.

In the manufacture of notes, in particular Banknotes are used to increase profitability increasingly striving to work simplify and automate as much as possible. To belongs in particular also to the person-consuming process of manual counting, which takes place after the removal of the Sheet stack ensures that this is an exact predetermined Number of sheets included. At the exit of the printing press are generally from a chain gripper system transported note sheet over an open Magazine with adjustable bottom released on this Filed one on top of the other to form a stack of sheets and then transported in batches for further processing. To interrupt the printing process avoid when a stack of sheets reach its predetermined height has reached, are two side by side Magazines for the alternating formation of sheet stacks in the one and in the other magazine. Some in Printing methods used for banknote printing only allow limited stack heights. This is especially true for the Intaglio printing where the stack height is below Circumstances may be limited to 500 sheets, as well also for printing numbering with a High pressure inks that have long drying times can.

So far it is known in each of the two Magazine a certain number of separate Stack of sheets of predetermined height with the help of To produce magazine insertable stacking boards. To For this purpose, the magazine has a paternoster lift all-round slide-in system, which in predetermined distance from each other arranged receiving openings for inserting stacking boards, the one with a speed corresponding to the formation of the sheet stack be lowered. Once a stack of sheets is on a stack board of a magazine its predetermined Has reached stack height, the following coupons redirected to the second magazine, and in a new stacking board above the first magazine just inserted stack of sheets inserted; to Completion of the sheet stack in the second magazine the following sheets back into the first magazine on the new stacking board, etc.

Stacking boards for receiving sheet stacks, as in the The preamble of claim 1 specified are from known from US-A-3 641 949 and designed so that when stacking adjacent stacking boards in Relative to each other either a first relative position to the Formation of a tightly packed stack or a second relative position to form a self-supporting Take the work stack in which the stack boards have a predetermined vertical distance from each other. These are rectangular at the bottom Stacking boards hollow at all four corners, open at the top Feet are provided, which both when forming a Work stack as well as when forming a supply stack into the hollow feet of the stacking board underneath intervention. The bottoms of the hollow feet are however forming protruding up, down open locking cams deformed so that in the event of a tightly packed stack of supplies Stacking boards in the locking cams of the feet of the one above Intervening stacking boards while in formation the bottom of the feet of a work stack a stacking board on top of the cams of the feet of the stacking board underneath, which Height of the locking cams is the depth of engagement of the feet adjacent stacking boards limited. To protect the feet before damage are known at all corners Stacking boards the wall sections covering the feet laterally provided, the length of which is dimensioned just as large is like the length of the feet, so the weight of the Stacking boards on the feet and these wall sections is distributed. Between these provided at the corners Wall sections is however in the case of a work stack a stack of sheets lying on a stacking board freely accessible from the side.

The present invention is based on the object Stacking boards to hold sheets, especially stacking sheets of notes to train so that their handling prevents single sheets removed from a work stack without authorization can be.

This task is for a stacking board, which with hollow feet and hollow locking cams according to the The preamble of claim 1 is provided, in which characterizing part of claim 1 specified features and for a stacking board of another configuration, without hollow feet, by the specified in claim 4 Features resolved.

In this way, you can not only create a work stack, in which the distance between adjacent support plates greater than the thickness of one placed on it Is a stack of sheets, and a tightly packed stack of supplies produce whose height when adding a pallet only increases approximately by the thickness of a support plate, but it is also guaranteed by the fuse strips, that in a work stack all sheets are stacked are completely covered on all sides and thereby access to the arch is blocked what a unauthorized removal of sheets.

Appropriate embodiments of the invention result from the dependent claims.

The invention is based on the drawings Exemplary embodiments explained in more detail.

The stacking board shown in Figures 1 to 3 has the shape of a pallet 1 with a rectangular shape Support plate 1 'for receiving the stacked Note sheet. The size of this support plate is Dimensions of a note sheet B adapted as he is indicated in the top view according to FIG. 7. On opposite longitudinal edges 1b and 1a of the Support plate 1 are two hollow feet 2 and 3, respectively protrude on the underside of the support plate, and each two hollow locking cams 4 and 5, which are also on protrude from the underside of the support plate by means of Screws 6 attached. The one on the longitudinal edge la in the same Hollow distance from the corners of the support plate attached Feet 3 are the hollow locking cams 4 on the other Longitudinal edge 1b opposite, while each at a distance of the hollow feet 3 attached to the longitudinal edge la hollow locking cams 5 the hollow feet 2 on the other Longitudinal edge 1b are opposite.

The hollow feet 2, 3 are open at the top and conical trained so that the feet of another Can intervene in the pallet. The hollow locking cams 4, 5, the length of which is only a fraction of the length of the hollow feet 2, 3 is also open at the top and conical in such a way that in one hollow locking cams 4, 5 either the end of a hollow Foot or a hollow latching cam of a patch Pallet can intervene.

On all four edges of the Pallets are protruding downwards, diagonally outwards Directional fuse strips 9 attached, their importance mentioned later and which in the figures are shown transparently.

The described arrangement of the hollow feet and the hollow locking cams so that the hollow feet on the a longitudinal edge of a pallet 1 the locking cams on opposite the other longitudinal edge of this pallet, and conversely, it allows two different ones To form pallet stacks. When pallets 1 are stacked on top of each other that all edges la and so also all edges 1b lie one above the other and therefore all Feet of an attached pallet in the hollow feet the underlying pallet can and at the same time all locking cams on a pallet into the hollow locking cams of the pallet underneath intervene, a tightly packed stack of supplies is created 7, as shown in Figure 4. In this stack of pallets, that in the example considered from FIG. 4 there are fifteen pallets 1, the support plates 1 ' of all pallets practically on top of each other so that this Storage stack takes up the smallest possible space. To it is of course necessary that the lengths of the Feet 3, 4 and the lengths of the locking cams 4, 5 and so their depths of engagement are such that feet and Locking cams when stacking the pallets together all of their protruding parts on the underside of the pallet Length in the feet or locking cams of the one below Pallet can be sunk.

On the other hand, if the pallets 1 are stacked like this, that every other pallet is rotated by 180 ° is, based on the stock stack 7, that in each case a longitudinal edge 1b over a longitudinal edge 1a, and vice versa, then feet 2, 3 can be one Pallet each in the hollow locking cams 4, 5 of the Intervene pallet underneath, creating a work stack 8 according to FIG. 5 arises. This Work stack has eight pallets, the bottom of which seven pallets according to FIG. 7, each with a sheet stack S are occupied and the top pallet only as a cover serves.

The support plates 1 'of the pallets have one predetermined distance from each other that is determined by the difference in the length of a hollow foot 2, 3 and the small depth of engagement of a foot end in a locking cam of the pallet underneath. This Distance between pallets 1 in a work stack 8 is the height of a sheet stack S that is on a Pallet should be stored, adjusted so that between the top sheet B of a stack S and the Plate the pallet above a small one Leeway remains; all sheet stacks S are therefore from Weight of the pallets and sheet stacks above completely relieved. The weight of a stack of sheets is from the feet of a pallet to the feet of the transfer the underlying pallet. One on one For example, a stack of sheets S to be deposited can be deposited 500 sheets of note B.

By snapping the foot ends into the hollow ones Latch cams 4 and 5 are self-supporting, very stable, practically rigid pallet stack, the as a stack 8 simply as a safe whole manipulated, e.g. raised, moved or placed on a trolley 30 (Figure 10) can be.

The mentioned fuse strips 9 of a pallet 1 blankets in a work stack 8 (Figures 6 and 10) the sides of the stack of sheets on the one below Pallet and thus prevent that Note sheet with fraudulent intent on the side can be pulled out. The top sheet stack S on the seventh pallet is through the fuse strips the top eighth pallet. In one Storage stacks 7 (FIG. 4) grip the fuse strips 9 because of their outward inclination one above the other and therefore allow a tight packing.

A complete work stack 8 can then be easily moved using a trolley 30 (Figure 8) as a whole by moving in known way in height relative to the Wheel axis adjustable platform of this cart 30 in lowered position under the work stack 8 pushed and then, by means of the acting as a lever Handle, is brought into the raised position, in which the feet of the bottom pallet touch the floor no longer touch.

FIGS. 9 to 18 are a second embodiment a pallet according to the invention and the with these pallets formed supply stacks and work stacks shown. According to FIGS. 9 to 12 the pallet 31 has a rectangular, a sheet stack B adapted support plate 31 'on which three sides three downward facing lower walls 32, 33 and 34 and on the fourth side one up directed upper wall 35 are attached or molded. The upper wall 35 and the opposite wall bottom wall 33 form a with the support plate 31 ' right angle while the other two bottom ones Walls 32 and 34 run obliquely outwards. The Side edges 35a of the top wall 35 are such bevelled so that it inclines the lower walls 32 and 34 are adjusted and when a Work stack 38 (Figure 18) between the side Ends of these sloping walls 32 and 34 one overlying pallet 31 practically completely can intervene. These walls 32 to 35 form simultaneously the support elements and the fuse strips.

When a supply stack 37 is formed (FIGS. 13 and 17) are pallets lying directly one above the other 31 each offset by the thickness of its upper wall 35 placed close together, with the lower, sloping towards outside walls 32 and 34 of a pallet lower, sloping walls 32 and 34 of the underlying Overlap the pallet. All pallets 31 are nested one on top of the other.

It is for storing a supply stack 37 expediently, as shown in Figure 13, a To provide support base 25, the surface of two sloping and adjacent at right angles Surfaces 25a and 25b exist so that the Pallets 31 stacked one on top of the other in a tilted position can be, the support plates parallel to one sloping surface 25a and the upper walls 35 parallel to the other inclined surface 25b.

To form a work stack 38 (FIGS. 15 and 18) the pallets, in the same orientation like stacking up a stack, however, such that the top walls 35 and the lower walls 33 opposite these Pallets lie exactly on top of each other. It takes effect the top wall 35 of a pallet between the sloping extending lower walls 32 and 34 of the overlying Palette, taking a certain Can provide clamping effect. In a work stack 38 have the upper walls 35 and the opposite walls lower walls 33 the actual supporting function, which ensure the stability of the stack, and all walls 32 to 35 cover the sheet stacks completely so that no sheets are removed can be.

A precisely adjusted position of the one Can facilitate work-stacking pallets on those lying one on top of the other in a work stack Surfaces of the pallet locking elements are provided, namely on the one hand latching cams or raster elevations and on the other hand, corresponding recesses, which at of stacking interlock. With these themselves surfaces supporting one another are on the one hand around the edges of the walls parallel to the support plate 33 and 35 and on the other hand for the extension edge areas of the support plate lying on these walls the support plate side opposite this wall.

Examples of such are shown in FIGS. 11 to 14 Locking elements schematically illustrated (such Locking elements are not in the other figures shown). So on the top edge of the top Wall 35 ridges 40 and on the bottom of the Support plate 31 ', below this wall 35, corresponding Locking recesses 39 may be provided, in which at Forming a work stack the grid increases 40 of intervene below the pallet. Instead of this Locking elements or in addition to these locking elements can also grid increases 40 'on the lower edge of the lower wall 33 and corresponding locking recesses 39 ' on the top of the support plate 31 'above the wall 33 be attached, these locking elements when forming of a work stack also interlock. These locking elements are of course arranged so that not the dense pack of a stack of supplies hinder. So in the example of Figure 13 are Elevations 40 and 40 'of a pallet next to the edge of the underlying pallet. In the event that grid increases 40 'provided on the lower edge of the wall 33 are of course the bottom pallet of a work stack 38 with these grid increases 40 'on the Floor or a mat. The horizontal orientation the base plate of this lowest pallet then by an appropriately sized, later explained support block 41 (Figure 15) guaranteed.

It is also possible on the bottom edge of the wall 33 notches and on the top of the support plate 31 'above the wall 33 raster elevations, so that the bottom range is one Pallet stack supported on the lower edge of the wall 33. In this case, to get a tight package of a To achieve stockpiles are on the bottom the support plate 31 ', immediately next to the wall 33, still appropriate recesses are attached such that the grid increases when forming a supply stack the top of a support plate in the locking recesses on the underside of a support plate arranged above intervention. This ensures that in Storage stack 37 the support plates lie tightly packed one on top of the other and at the same time additionally through this Locking elements are adjusted in their position.

In order to create a work stack to ensure a stable fit of the lowest pallet, is in the example considered night Figure 15 a separate support block 41 is provided, which the missing top wall of a nonexistent one underneath located pallet replaced and their supporting function takes over. Of course, you could also have a special with such an additional support element make the pallet below the top wall, which is the bottom pallet of a work stack forms. However, since it is generally more economical and is more appropriate, only with pallets Working in the same shape is generally that Use of a separate support block 41 for the bottom pallet of a work stack cheaper.

Since the sheets of notes to be stacked in general are not completely dry yet at least one of the walls of a pallet 31 vents 36 provided, as in Figure 12 for the lower Wall 32 indicated. This will make the complete Favors drying of the arches. Of course you can such ventilation openings are provided in all four walls his.
