Definitions
- the invention relates to a device for adaptation of the negative pressure in a suction belt feed table Sheet feeder changing during sheet feeding Operating conditions, with at least one endless, rotating drivable conveyor belt, which with suction openings is provided with a side alignment device for lateral alignment of the foremost bow of each scaled arc stream and with one below one Conveyor plane arranged suction box, which, in Seen sheet conveying direction, divided into several suction chambers is the pressurizable are.
- the Japanese Utility model disclosure Hei 4-91953 is a device known to switch the suction effect.
- An articulated stored actuating cylinder rotates one using a lever Rotation axis on which a flap provided with two sealing surfaces is attached.
- the flap can either connect to atmospheric pressure level or a connection with a Vacuum source can be realized.
- This device is disadvantageous in that a complete 90 ° swivel movement of the flap got to. This has the consequence that, due to the inertia of the mass to be pivoted, a certain pivoting time is required. So there is none during the pan time clearly defined switching state. At high Sheet conveying speeds is therefore an abrupt, atmospheric ventilation of a suction chamber not possible.
- the promotion of a shingled stream of arcs on the A feeder table of a sheet-fed rotary printing press can be divided into three phases.
- the first phase leaves are characterized in that the first sheet from the separating device to the Suction belt is pushed, as little slip as possible on the perforated conveyor belt to be sucked.
- the suction power is fundamental to machine operation reduced by the fact that only a certain area of the Conveyor belt is covered by the first sheet and thus a lot of incorrect air is sucked in, the suction effect is limited.
- the first phase is particularly critical, though with a small scale length both with and without Driving rollers on the belt drive roller at the top of the Feeding table is being worked.
- the third phase of the promotion of a shingled stream of arcs concerns the promotion of the last sheet of the scaled Arc current.
- This arch is on along its entire length the conveyor belt is sucked and is therefore much stronger fixed on the conveyor belt as the partially overlapping arc of the shingled stream. With this If the individual sheets overlap, the sheets only with a fraction of their area with the conveyor belt in Contact, resulting in less suction are subject.
- the last bow remains with his Transport against the front brands in the feed table exposed to negative pressure, on the one hand the Front edge of the last sheet on the front marks indented and on the other hand not the lateral alignment be insignificantly disabled.
- the invention has for its object the negative pressure in Feed table of a sheet feeder of the respective operating phase adapt.
- the pivotable Shut-off element in the plane of a boundary of the suction nozzle is arranged. It does not form any in a passive position Flow resistance in the suction nozzle and allows a smaller one Dimensioning of the suction air source.
- pivotable shut-off element eccentrically on one Swivel axis attached which is characterized by the eccentric Storage, based on the swivel axis, resulting shorter Section of the pivotable shut-off element closes or opens a ventilation opening in a boundary wall of the suction nozzle.
- the eccentric bearing resulting longer section of the shut-off element interrupts the connection of a suction chamber to the common suction nozzle.
- the suction chambers are on trusses below the conveyor level of the arc stream attached.
- the trusses in turn are penetrated by breakthroughs outside the Swivel range of the shut-off element are. This gives themselves that the suction chambers, their respective suction channels through the breakthroughs permanently with the common suction nozzle connected, consequently permanently subjected to vacuum are and none by the pivoting movement of the shut-off element Experience influence.
- is located at the Trusses each have a suction box into which the front and open rear suction chambers.
- the actuation of the pivotable shut-off element is both with a a pressurized actuating cylinder as well electromagnetically realizable.
- the invention is based on a drawing explained in detail.
- FIG. 1 shows that a conveyor level 5 to supply one sheet-fed rotary printing press Has suction chambers I, II, III, each of curly Brackets 1, 2, 3 are overlapped.
- the suction chamber I is located directly adjoining a belt drive roller 8, behind a pivotable stop 6 one Feeder stack 4.
- the front suction chamber I extends to to a first web 12 below the conveyor level 5.
- a middle suction chamber II which extends up to a pull roll 10 of a side aligner extends.
- a rear one Suction chamber III formed by a sheet metal part of the middle suction chamber II is separated. Behind the Conveying level 5, the front marks 11 are arranged on which the individual sheets are aligned.
- the housing in which the suction chambers I, II, III are formed are attached to trusses 14 and 15, which are transverse extend to the conveying direction of the arc stream.
- the two Trusses 14 and 15 serve as storage points for the ends a pivot axis 20 on which a shut-off element 17 is attached.
- the shut-off element 17 is by means of a Screw 21 added to the pivot axis 20.
- the Traverse 15 receives an abutment 22 in which Actuator 18 is articulated at the end a control fork 19 is attached, the retraction and extension causes rotation of the pivot axis 20.
- a rear suction box 24, in the a suction channel of the suction chamber I opens.
- Both trusses 14 and 15 are provided with openings 16, whereby the Suction boxes 23 and 24 with the common suction nozzle 38 in Connect.
- the suction nozzle 38 is of the two Trusses 14 and 15 limited, as well as on its underside completed by a sheet 29 on which a strip-shaped Seal 26 is attached. This serves as a stop for an end portion of the shut-off element 17 while above of the shut-off element 17, a further seal 25 is provided to which the other end of the shut-off element 17th strikes.
- Figure 2 shows a cross section through the feed table in the Operating phase promotion of the 1st sheet.
- the housing is accommodated in the center in the conveying plane 5, in which the suction chambers I, II, III are formed and around which rotates the endless conveyor belt 9.
- the Funding level 5 is limited by feeder side parts 31. Between the side parts 31 and the suction chamber housing extend table plates.
- the cross member 15 extends between the investor side parts 31; that's about her Abutment 22 of the actuator 18 added.
- the Control fork 19 stands with the pivot axis 20 via a lever in connection.
- the pivot axis 20 divides the pivotable Shut-off element 17 in this embodiment approximately in 2: 1 ratio.
- the eccentric arrangement of the Shut-off element 17, based on the pivot axis 20, causes a division of the shut-off element 17.
- the shorter side gives in the representation shown in Figure 2 an atmospheric Ventilation opening of the middle suction chamber II free; the middle suction chamber II does not suck. Accordingly becomes eccentric through the elongated section of the stored shut-off element 17 the connection of the middle Suction chamber II interrupted with the suction nozzle 38. Since the Openings 16 in the areas of the cross members 14 and 15, that limit the suction port 38, are included outside the swivel range of the shut-off element 17 the vacuum is in suction chambers I and III regardless of the position of the shut-off element 17 continues on. The shut-off element 17 takes the in this operating phase Position 36 a.
- the suction port 38 is in the embodiment shown from several sheets 27, 28 and 29 To form suction nozzle 38 tubular, with a deviating geometry of the shut-off element 17 would result.
- the Using a rectangular tube would be also conceivable.
- the suction air in suction chamber I flows into the rear suction box 24 a.
- the openings 16 in the cross member 15 flows the suction air into the suction port 38, regardless of the working position of the shut-off element 17th
- the suction air flow acting on the middle suction chamber II is with the shut-off element 17 down (see Figure 4) sucked through the suction port 38.
- This in Suction chamber III pending vacuum is above the front Suction box 23 and the openings 16 in the cross member 14 with the suction nozzle 38 - regardless of the working position of the shut-off element 17 -.
- FIG. 4 an illustration of the section IV-IV from FIG. 3 is the working position 37 of the shut-off element 17th reproduced.
- a fully developed arc current see Fig. 3
- the shut-off element 17 down pivoted, whereby the vacuum prevailing in the suction nozzle 38, also in suction chamber II below the scaled Arc stream promoting conveyor belt 9 is present.
- Working position 37 closes the rear section of the eccentrically mounted shut-off element 17 the atmospheric Ventilation opening between pivot axis 20 and Seal 25 on the face plate 28.
- the working position 36 of the Shut-off element 17 enables the ventilation of the Suction chamber II, while the suction chambers I and III, analogous to Promotion of the 1st sheet 32 with the suction port 38 in Stay connected.
