- the preferred made of plastic valve plate 10 has a channel 19 with an opening 11 on which a flexible vacuum line 16 is connected to a vacuum pump 2 or another vacuum source.
- a central, continuous Bore 15 takes a hollow shaft 5 of an opening drum B. or C.
- the valve plate 10 is with a machine housing 4 connected and thus arranged with respect to the shaft 5.
- the channel 19 runs radially and besides that opening 11 arranged on the circumference, a further opening 18, which are directed against the sliding body 12 in the axial direction is.
- the valve plate 10 is preferably attached to the housing 4 in such a way that they are loosened and rotated and thus the Opening 18 can be adjusted in the circumferential direction.
- the sliding body 12 has a central bore 34 with a Groove 14 for receiving the shaft 5 and a wedge 13.
- the wedge 13 engages in the groove 14 and connects the sliding body 12 rotatably with the shaft 5.
- a kidney-shaped opening 20 is incorporated into the sliding body 12.
- an edge in the sliding body 12 Recess 21 incorporated, which forms a ventilation opening.
- the control disc 22 has an axially projecting, cylindrical Part 25 and a disc-shaped part 35.

- the part 25 For turning the control disc 22 in the directions of the double arrow 24 is the part 25 connected for example with two bevel gears 26.
- the spur gears 26 and the lever 27 only form an example of a suitable adjustment option 40.
- Figure 3 shows two suction drums B and C, each at least have a sucker 6 and serve envelopes or folded sheet 38 with a top fold 38a on one here only deposit chain shown hint 29.
- On the two suction drums C and B is another known per se Drum A arranged which the envelopes or folded sheets of pull off a stack not shown here and the two Feed suction drums B and C.
- the envelopes to be opened or folded sheet 38 get from above between the two suction drums B and C, which rotate against each other according to arrows 37.
- FIG. 3 there is a folded sheet 38 between the two suction drums B and C, so the two Rag of this sheet 38 sucked through the suction cups 6.
- the Suction cups 6 are according to FIG. 2 on the corresponding shaft B. resp.
- suction cups 6 rotate with the shaft 5 and are depending on the position of the rotary valve 1 with the Vacuum source 2 or via the ventilation opening 21 with the ambient air connected.
- Figures 1 and 2 show a position of the rotary slide valve 1, in which the suction cups 6 are connected to the vacuum source 2 and are thus active.
- the kidney-shaped opening 20 of the sliding body 12 is in a position in which it connects the channel 19 of the valve plate 10 with the passage 23 of the control disk 22.
- Line 8 shows the connection that leads from vacuum openings 6 to vacuum source 2.
- the opening 20 in the suction drum C rotates clockwise.
- the opening 18 is located at the start of the kidney-shaped opening 20. This position of the opening 20 relative to the opening 18 determines the starting point of the suction angle. If the sliding body 12 rotates clockwise with the opening 20, the suction devices 6 remain connected to the vacuum source 2 and are thus active.
- FIG. 7 shows the position on which ambient air flows to the suction devices 6.
- the suckers 6 are thus aerated and the folding sheet 38 is released from the opening drums B and C and dropped onto the collecting chain 29.
- FIG. 6 shows this position of the suction cups 6, which, as mentioned, are ventilated and are therefore inactive. It is essential that this ventilation position is determined by the rotational position of the control disk 22 and in particular of the passage 23. If this ventilation position and thus the time at which the folded sheets 38 are released are to be adjusted, the passage 23 is adjusted by rotating the control disk 22 in the directions of the arrow 24.
- the adjustment range is indicated by 31 in FIG. If passage 23 is adjusted counterclockwise in FIG. 4, so the suction cups 6 are ventilated earlier and thus the Reduced suction angle. When moving the passage 23 in In contrast, clockwise ventilation is performed later.
- FIG. 6 clearly shows the overlap of the passage 23 with the ventilation recess 21.
- the suction openings 6a are thus connected to the ambient atmosphere via the passage 23 and the ventilation recess 21.
- the kidney-shaped opening 20 is located outside the opening 18 and is therefore not connected to the vacuum source 2.
- a significant advantage of the rotary slide valve 1 is seen in the fact that the vacuum source 2 does not suck into the void, but is closed according to FIG. 8 by the covering of the opening 18 by the sliding body 12.
- the suction of the suction cups 6 thus takes place at a freely selectable point in time which is dependent on the position of the control disk 22 relative to the sliding body 12. Since, as mentioned, the control disc 22 is adjustable in the barrel, the ejection behavior, respectively. the time at which the sheets 38 are dropped onto the collecting chain 29 is optimized and the running speed is thus increased. In principle, this is also possible with the rotary slide valve 51 shown in FIGS. 9 to 12, which is explained in more detail below.
- the rotary slide valve 51 is also on a hollow shaft 65 put on, which has a channel 67 with an opening 69.
- a sliding body 72 has a central blind bore 70, in which engages the hollow shaft 65.
- the channel 67 is permanent and airtight with a radially extending one Breakthrough 68 connected on a flat back 78 emerges in a radially extending opening 79, as Figure 12 clearly shows.
- the slider 72 slides with its flat surface 78 on a valve plate 60, the preferably made of plastic and standing on the Machine frame not shown is attached here.
- valve plate 60 In the surface 80 of valve plate 60 abutting sliding body 72 a recess 63 is worked in, which according to FIG is crescent-shaped and about half one in the middle arranged through hole 64 receives.
- the valve plate 60 is preferably attached to the machine frame in such a way that it can be loosened and rotated.
- a Slider 52 used, which has a cylindrical part 53, which according to Figure 12 on the back of the valve plate 60 stands out.
- a guide pin protrudes 81 of the sliding body 72 in a bore 54 of the Slider 52 into it.
- a radially protruding arm 55 is divided the recess 63 according to FIG. 11 in two chambers 73 and 74.
- the recess 63 has two radially extending bores 59 and 61 connected, one according to Figure 9 on the circumference have emerging opening 58 or 71.
- the opening 71 is via a flexible hose, not shown here, with the Vacuum source 2 connected.
- the other opening 58 is open to Ambient atmosphere.
- the chamber 73 is thus independent of the position of the slide 52 with the ambient atmosphere and chamber 74 is connected to vacuum source 2. The mode of action is below with reference to Figures 10 to 15 the opening drum B explained.
- the opening drum B has at least one suction device 66 a suction opening 66a and rotates in the direction of arrow 82.
- the shaft 65 and the sliding body 72 rotate in the same Direction.
- the breakthrough 68 connects thus the channel 67 of the hollow shaft 65 with the bore 61 and thus with the vacuum source 2, as in FIG. 12 using the line 76 clearly shows.
- the suction opening 66a is thus with the vacuum source 2 in connection. This connection is maintained until the breakthrough 68 via opening 79 the chamber 73 reached and thus through the bore 59 and the opening 58 is connected to the ambient atmosphere.
- the suction cup 66 is aerated with it.
- the opening drum C rotates in the opposite direction, but works otherwise same as the opening drum B. Both drums B and C have its own rotary slide valve 51 and can thus can be set independently. Is essential here, too, that when the slide 52 is adjusted, the time of ventilation, but not the suction time is adjusted. Adjusting the time of suction is essential possible by rotating the valve plate 60. Go berserk the valve plate 60 in one of the directions of the double arrow 62, the suction edge 83 is rotated clockwise accordingly.
- the suction device 66 is activated earlier, in the other case the activation takes place later.
- the ventilation time would be adjusted, but what can be prevented by holding the slide 52 can.
- the slide 52 can also be adjusted via Bevel gears 26 or another suitable adjustment respectively.
- Figures 13 to 15 show the rotary slide valve 51 in the Ventilation position.
- the breakthrough 68 is thus here with the Chamber 73 connected, which in turn connects to the bore 59 owns.
- the adjustment range of the slide 52 is in Figure 14 indicated by the double arrow 75. Will the angle according to double arrow 75 as reduced in Figure 14, so the suction cups 66 are ventilated earlier. The suction time, however, is not changed.
- arrow 77 shows indicated the way through which ambient air to the suction cups 66 streams.

Abstract
Description
Beim erfindungsgemässen Drehschieberventil kann hingegen bei festem Saugzeitpunkt der Belüftungszeitpunkt und damit die Grösse des Saugwinkels in einem vorbestimmten Bereich verstellt werden. Durch die Verstellung des Belüftungszeitpunktes wird der Saugwinkel kleiner oder grösser.
Vorzugsweise weist das Drehschieberventil einen Schieber auf, der im Lauf zur Veränderung der Grösse des Saugwinkels verstellbar und insbesondere drehbar ist.
In einer bevorzugten Ausführung besteht das Drehschieberventil aus einer Ventilplatte, an welcher die flexible Vakuumleitung angebracht ist, einem Gleitkörper sowie einer Steuerscheibe als Mittel zum Verstellen der Grösse des Saugwinkels. Der Gleitkörper ist fest auf einer Welle befestigt und rotiert mit dieser mit. Die stehende Steuerscheibe ist am äusseren Ende der Welle angeordnet und besitzt einen achsialen Durchgang, der durch einen Durchbruch des Gleitkörpers mit einem Saugkanal verbindet. Dieser Saugkanal führt vorzugsweise durch die Welle der Öffnungstrommeln.
Bei einer Variante der Erfindung weist die Ventilplatte eine sich in Umfangsrichtung erstreckende Ausnehmung aus, in welcher ein Schieber gelagert ist, der diese Ausnehmung in zwei Kammern unterteilt. Die eine Kammer ist durch einen Durchgang mit der Vakuumquelle und die andere Kammer über einen Durchgang mit einer Belüftungsöffnung verbunden. Auch diese Ausführung erfordert im wesentlichen nur drei einfache und robuste Teile.

- schematisch eine weitere Ansicht des Drehschieberventils gemäss Figur 9, und
- Fig. 15
- schematisch einen weiteren Schnitt durch das Drehschieberventil gemäss Figur 9.
In Figur 8 zeigt die Linie 30 den Weg, auf dem Umgebungsluft zu den Saugern 6 strömt. Die Sauger 6 werden somit belüftet und der Faltbogen 38 wird von den Öffnungstrommeln B und C freigegeben und auf die Sammelkette 29 abgeworfen.
Die Figur 6 zeigt diese Position der Sauger 6, die hier wie erwähnt belüftet und damit inaktiv sind. Wesentlich ist nun, dass diese Belüftungsposition durch die Drehposition der Steuerscheibe 22 und insbesondere des Durchgangs 23 bestimmt ist. Soll nun diese Belüftungsposition, und damit der Zeitpunkt, zu dem die Falzbogen 38 freigegeben werden, verstellt werden, so wird der Durchgang 23 durch Drehen der Steuerscheibe 22 in den Richtungen des Pfeils 24 verstellt.
Ein wesentlicher Vorteil des Drehschieberventils 1 wird darin gesehen, dass die Vakuumquelle 2 nicht ins Leere saugt, sondern gemäss Figur 8 durch die Überdeckung der Öffnung 18 durch den Gleitkörper 12 verschlossen ist. Die Belüftung der Sauger 6 erfolgt somit zu einem frei wählbaren Zeitpunkt, der von der Stellung der Steuerscheibe 22 relativ zum Gleitkörper 12 abhängig ist. Da wie erwähnt die Steuerscheibe 22 im Lauf verstellbar ist, kann das Abwurfverhalten resp. der Abwurfzeitpunkt der Bogen 38 auf die Sammelkette 29 optimiert und somit die Laufgeschwindigkeit erhöht werden. Dies ist grundsätzlich auch bei dem in den Figuren 9 bis 12 gezeigten Drehschieberventil 51 möglich, das nachfolgend näher erläutert wird.
