Description

The invention relates to a foldable stacking table on a printing machine or the like, with a front part and an articulated rear part and with lateral guides for a stack arranged on the rear part.

On a known duplicating machine (US-PS 22 16 692) is a stacking table of the above described type is provided, the rear part can be folded up by articulation by means of hinges on the front part, so that thereby the duplicating machine can be locked when not in use. The stacking table also has lateral guides for a stack that extend over the articulation point of the The rear part extend away and for this reason are also in two parts, their parts being articulated are connected to each other in order not to hinder the folding up of the rear part.

Due to this construction of the well-known stacking table, «there is no way to put one on it precisely and sensitively to adjust the stack located in relation to the printing cylinder of the machine, like that of stacking tables for the sheet feeder sheet processing machines is known per se (DT-AS U 91 831).

The invention is therefore based on the foldable stacking table of the type described above the task is to train this so that a quick and sensitive lateral alignment and Adjustment of the stack is possible. once the setting has been selected, even if the high- and folding down the stacking table can be maintained.

According to the invention this object is achieved in that the rear part together with the side Guides for the stack can be adjusted in a manner known per se in the transverse direction with respect to the front part, that an adjuster for the rear part has a notch on one part and a projection on that Has another part of the stacking table, wherein the notch and projection are arranged so that they are in one certain setting of the rear part relative to the front part when folding down the rear part in engage its operating position in each other, and that at least notch or projection in the transverse direction the associated part of the stacking table adjustable, but secured against involuntary adjustment is.

In the case of the stacking table according to the invention, the setting of the rear part once made is thus relative to the front part - and thus that of the stack relative to the printing cylinder - through the with the Protrusion defines cooperating notch. The projection lifts out of the notch at Fold up the rear part so that the adjustment device does not hinder the folding up. Consequently the rear part can be moved in the transverse direction into the position that it requires for proper functioning Sealing of the printing machine is required. However, when you fold down the rear part again The protrusion and notch interlock again so that it is ensured that the rear part and the one on it arranged lateral guides resume their previously set position in the lateral direction. University

To find this position easily, it is provided according to a further development of the invention that the notch widens towards its opening. As a result, the projection slides along the flanks of the notch to its base, taking the rear part of the stacking table with it into the defined lateral position

According to an advantageous embodiment, the projection or the notch is arranged at one end of a lever which is hinged to the rear part of the stacking table, the lever having a pivoting resistance that it maintains its angular position without arbitrary adjustment. The lever is preferably mounted below the surface of the rear part, so that on the one hand it does not come into conflict with sheets when they are placed on the stacking table, on the other hand it is not unintentionally adjusted during operation of the printing press. The arrangement is such that the pivoting of the lever when the projection and notch intermesh results in a relative movement of the rear part in the lateral direction with respect to the front part.

In order not to take into account the transverse divisibility of the rear part, which is provided according to the invention Having to take the side guides for the stack is according to a particularly preferred embodiment the invention provided that the side guides for the stack with the rear part in one are pivotably connected to this perpendicular plane, extend over the front part and on it rest. The side guides are otherwise not connected to any part of the stacking table, so that when Fold up the rear part of the front end of each side guide slightly forward over the Front part moves while the rear end of the side guides is raised and at the same time Pivoting is moved slightly forward.

The present invention permits careful alignment and adjustment of the stacking table and the attached lateral guides opposite the cylinder of the printing machine, the once made The setting is constantly maintained, even if the stacking table is raised and returned again so often is folded down. The stacking table is designed so that the side guides attached to it can be adjusted for the stack in the side-to-side direction without having to use them to fold up the Rear part must be brought into a special position. With the rear part folded up the side guides take up little space. They can therefore be tall, long to the extent required and also be made stiff.

In an advantageous embodiment of the invention the lateral guides are each arranged transversely on one in a recess in the rear part Fastened rod and by means of a sleeve displaceable along the rod and clamped thereon. In this way the side guides can be in certain positions, e.g. B. according to certain paper widths, arranged and also in these positions with <, o Leave the rear part folded up. The lateral adjustment is thus without the arrangement annoying elongated holes on the machine.

A printing machine equipped with the stacking table according to the invention thus has a height ren ease of use, which pays off especially when the printing press repeats, however is used continuously. Main application

The field of the invention is primarily, but not exclusively, the field of printing or copying generation machines with a small footprint, e.g. B. table, Printing and reproduction equipment.

Further expedient embodiments of the invention are marked in the sub-claims.

The invention is described below on the basis of a preferred exemplary embodiment. It shows

Fig. 1 is a plan view of the top of a stacking table in the unfolded state, in the front and rear part lie in the same plane,

F i g. Figure 2 is a section along line 11-11 in Figure 1;

3 shows a partial section along the line III-III in Fig. 2;

FIG. 4 is a side view of that shown in FIG Stapeitisches, broken open and partly in section, in the unfolded state as in FIG. 1, and

FIG. 5 shows a representation similar to FIG. 4, in which however, the rear part of the stacking table is folded up into the closed position.

As can be seen from the drawings, the stacking table consists of a front part t and a rear part 2, which can be folded around joints 9 with respect to the front part t. The front part 1 is on vertical Running bodies 5 mounted, along which it can be adjusted in the vertical direction and the between lateral cheeks 3 of a printing machine are arranged and attached. The rear part 2 is along the joints 9 adjustable across the direction of transport. It extends a certain distance in front of the transport direction Joints 9 which are attached to the rearwardly protruding lateral fingers of the front part 1. At the rear 2 lateral guides 4 are provided for the stack, which slide by means of sleeves 6 on rods 11 and by means of Clamping screws 6 'can be clamped on it. The rods II are in recesses 8 in the rear part 2 of the Stacking tables arranged.

1, 2 and 3 further show an embodiment of a transverse adjustment device for implementation the lateral adjustment of the rear part 2 with respect to the front part 1, whereby the free adjustability of the rear part 2 along the joints 9 is utilized. A lever 12 is articulated at 7 on the rear part 2 and has a handle 13 in the area of the rear edge of the rear part 2 remote end 100 of lever 12 engages a notch 10/4 of a plate 10, which is arranged just below the rear edge of the front part 1 and of this is held. A pivoting of the lever 12 about its articulation point 7 by means of the handle 13 to the right or left causes a shift of the rear part 2 in the same direction, but in lesser extent. This enables a simple and precise transverse adjustment of one between the lateral Guides 4 held sheet stack relative to the impression cylinder of the printing machine. The lever / notch arrangement in no way affects the Hochkiuppen of the rear part 2, since the lever 12 of this Rear part 2 is held and can lift out of the plate 10 when the rear part 2 is in the Is folded closed position. The rear part 2 of the stacking table is often in lateral direction are brought into a certain position relative to the rear of the printing machine need to complete this properly. Its previously set bank angle can, however, be restored again Easily find the unfolded state if the lever 12 is not between folding up and down

has been moved. For this purpose it owns the notch 10Λ in the plate 10 diverging flanks (Fig. 3). When the rear part 2 is folded down, the inclined flank of the notch 10/4 arrives with the Hebclende 10ß in engagement, whereby the rear part 2 with the lever 12 in the transverse direction is moved until the lever 12 is correctly in the bottom of the notch 10A in the plate 10. To ensure, If this also occurs, the resistance of the lever 12 against pivoting about its pivot point should greater than the resistance of the rear part 2 to lateral displacement on its joints 9 be. At least the lever 12 must be fixed in such a way that it does not move by itself under the action of gravity schwenki when the feed table is in the folded-up state.

As can be seen from the drawing, the lever 12 is preferably in the stacking table under its feed surface arranged, with the handle 13 lying within the edge of the stacking table to prevent that it is imposed, for example, in the clothing of a machine operator. It can of course more than one handle can be provided in order to carry out the lateral sliding movement.

From the F i g. 4 and 5 it follows that elongated holes are provided in the front part 1 of the Stapcliisches would have to accommodate the side guides 4 when folding up the rear part 2, if this is firmly with would be connected to the rear. The folding up into the closing position is shown in Fig.5. However enables the pivoting articulation of the lateral guides 4 by means of their rear corners on the Rear part 2 of the stacking table in the manner shown in the drawing that these rear corners of the lateral guides 4 when folding up the rear part 2 in the closed position upwards and forwards move while the front corners of the side guides 4 at the same time over a small distance run the front part 1 of the stacking table forward. As can be seen, the lateral ones protrude in this arrangement Guides 4 in the space above the front part 1 inside the machine, where they are closed

* Condition of the stacked table comparatively little space require.

The depth of the recesses 8 increases towards the front, so that when you fold up the Rear part 2 the bushings 6 and the rear edges of the

ίο side guides 4 not with the stacking table in Conflict come. Since the bushes 6 can be clamped with the cross bars 11, these are rotatable, but arranged in the longitudinal direction in the recesses 8 so that they can be folded up

is made possible. The lateral adjustment of the lateral Guides 4, which allow the adjustment to different widths of fed paper sheets, is only limited by the width of the recesses 8. However, a continuous recess would not be suitable because in this case the sheets of paper on the table surface of the stacking table are not sufficient at this point would be supported. The bushings 6 should be sufficiently robust and the side guides 4 should be as little be yielding that they work satisfactorily.

2> although the latter only on its rear lower edges are held.

The side guides 4 can be provided with small rollers 20 at their front corners so that they smoothly over the front part 1 of the stacking table beiiT

K> Folding up the rear part 2 run. According to the representation in the drawings, there is; Front part 1 two rearwardly extending lateral fingers which carry the joints 9. However, this feature would not be required if the front part 1 nit · ¹ ! it
