DEVICE FOR LAYING PAPER SHEETS OR THE LIKE

The invention relates to a device for superimposing paper sheets or the like, with a longitudinal traverse arrangement, by means of dikes, the paper sheets lying in parallel rows in a paper running plane in a paper running direction in the direction of the rows are successive in an assembly. with εinεr arranged below the paper running plane, associated with a row, lower vacuum traction unit, over which two sheets of paper coming from different rows can be placed in pairs, and with a transporting device, by means of which the pairs of sheets are simultaneously transferred from one another ωαbεi the vacuum transport is an endless conveyor belt provided with perforations, which has two deflection rollers mounted in a carrier and a vacuum chamber arranged between them is guided, which is open to the upper working strand of the conveyor belt adjoining the paper running plane.

The device according to the invention is used for superimposing sheets of paper, for example forms, which a cutting machine outputs in a two-use mode. A known device of the type mentioned at the outset according to DE 3k 33 7 A1 serves a similar purpose. In this known device, they are conveyed one after the other into the collating state in two rows of paper sheets. There is a cross G _{Z to the} direction of the paper, over εine vacuum - 2 -

comb-like, perforated, endless conveyor belt provided. With this conveyor belt, a paper sheet coming from the first row of paper sheets can be moved transversely to the direction of the paper, the other already in the assembly station, which is pushed by the second sheet of paper originating from the paper sheet. Leaching the transverse transport of the paper sheet must not only stop the other paper sheet, but also the feeding of further paper sheets must be interrupted. Only when the two papers in the collation station are completely overlaid, can they be removed from the collation by means of a paper direction in the direction of paper rotation. In the variant of this bεkaππtεn device the vacuum trap unit is sy metrically arranged in the middle between the two sheets of paper and the conveyor belt can optionally be driven in the same or another direction. On this sheet, paper sheets from the first row of paper sheets can be chosen from the first row of paper sheets over paper sheets from the second row of paper sheets and vice versa ωerdεπ. In this case, however, this known device operates discontinuously in time, ie the paper sheet feed and removal must be interrupted for the time, which is necessary to shift the paper sheet in the collating station. This results in a relatively long cycle time and a correspondingly low level of output. The clockwise operation of the device also causes greater noise. Furthermore, several stop bars are required in the assembly station in order to ensure the precise alignment of the paper to be moved transversely. 3 -

Ensure sheets. In the case of a format change, these stops must each be newly set up. Dεswεitereπ enables the known device only ever the shifting of paper sheets to one or the other side of the device, i.e. an overlay with a fixed edge arranged on the right or left. A centrally symmetrical stacking of paper sheets is not possible. The known device can also not be used universally for other modes of operation.

The invention is therefore based on the task of creating a device for overlapping paper sheets or the like of the type mentioned, which is characterized above all by high performance, thereby working precisely and reliably, in the case of formatting, requiring a number of changeover operations, and requiring multiple operations is adjustable.

According to the invention, this is

That the other row of paper sheets is assigned at least one similar, upper vacuum transport unit, above the paper runner, from which the lower working area of the conveyor belt to the paper running area and the vacuum chamber is open to the lower working area.

that the two ends, each of which carries one of the deflecting rollers of the associated conveyor belt, of each carrier in the direction of the paper offset from one another and can be adjusted independently of one another and by means of an element transverse to the direction of the paper, independently of one another, - i -

that in the assembly station between the bottom and the upper vacuum port, a step plate extending in the paper run is provided and

that in the paper running direction in front of the plate for each paper sheet is vαrgεseheheπ, mean ωεlchεr diε from a row comes from a row of paper sheets, which is assigned to the transport, the transport of the transport

wherein for the Übereiπaπdεrlεgeπ Papierblättεr dεr Trägεr zumiπdεst a Vakuumtraπsportεiπhεit means of Vεr- stεllεiπrichtuπg obliquely to Papiεrlaufrichtung dεrart eiπstεllbar is that sεiπ conveyor belt in auslaufseiti- geπ Berεich dεr Zusammeπtragstation krεuzt the conveyor belt of which is arranged on the side of the gεgεπübεrliεgεπdeπ Trεππplatte Vakuumtraπsporteinhεit.

The invention thus starts from the thought that the paper sheets coming from each sheet of paper are assigned a respective vacuum vacuum, of which the vacuum sheet row assigned to the vacuum transport row is arranged below and the other paper sheet is assigned to the other paper sheet above. The invention is based on the idea of arranging the vacuum - traπsportεiπhεitε-n so that its traπspαrt baths run essentially in the direction of the paper travel direction and the adjustment of the position of the conveyor belts is possible with the adjustment direction using the adjustment direction. To the - 5 -

The paper sheets can now optionally be set in such a way that, for example, the conveyor belt of the lower vacuum conveyor runs in the direction of the paper and the conveyor belt of the upper vacuum traverses the direction of the paper. Through this all paper sheets are moved from the upper vacuum carrier to the other side of the device, in which the lower vacuum transport unit is found, and it is possible to operate with a fixed flap on one side of the device. If the fixed edge is to lie on the other side of the device, the upper vacuum trapezoidal setting is adjusted so that its conveyor belt runs in the paper running direction and the lower vacuum tracing type is such that its conveyor belt runs obliquely to the paper running direction. It is also possible to set the lower and upper vacuum transport units so that the conveyor belts of both vacuum transport units run obliquely to the direction of paper travel to the longitudinal life of the device, which then causes the two

Paper sheets originating from the paper sheet are moved in the collating station to the longitudinal center and a centrally symmetrical paper color is possible. UJεitεrε εtriεbswεisεn dεr πεuεπ device are further explained below using the drawing. It is essential to the new device that the inclination of the conveyor belt or the conveyor belt across the paper running direction means that the paper sheets can be continuously overlaid. Depending on the setting of the conveyor belts, the paper sheet originating from one row of paper sheets in the direction of paper travel and that from the other row of paper sheets are combined - 6th

originating paper sheet obliquely for this purpose or the paper sheets from both rows of paper sheet originating obliquely to the paper running direction continuously conveyed further and thereby laid over one another. Due to the continuous operation of the πeuεπ device, known devices are known, e.g. the initially mentioned device, a significantly higher performance possible. For example, with the new device with a format height of approximately 75 mm (3 inches), 100,000 sheets per hour could be processed, while the previous work performance was only 25,000 Bla "per hour. Due to the continuous operation of the πεuεπ device, this works Finally, εin Forwε changes also only ωεnigε U stεllarbεitεn, that εnπ the kaπteπgεπau Aufεinaπderlεgeπ of the paper sheets can be done by adjustment of the rrrstsltεl that it is necessary that it is necessary to do so it is also possible that the paper sheets of one row of paper sheets can have a different width than that of the others (asymmetrical longitudinal section).

The subordinate statements in the sub-sections of the invention relate to particularly unfavorable developments.

The invention is explained in more detail below with the aid of an exemplary embodiment shown in the drawing. Show it:

Figure 4 - 11 diεmatic representations of various Betriebsueisεπ the device.

A printed paper web (not shown) is first divided into individual lengths in individual paper sheets 1, 2 and then also in this case, if not shown. The paper sheets 1, 2 lie in two mutually parallel rows R1 and R2 in a horizontal paper running plane E-E πebεnεinaπder and are moved by a transport device, not shown, in the paper running direction to the collapse station 3 shown in FIGS. 1 and 2. The direction of paper movement P runs in the direction of the rows R1 and R2.

At the entrance of this assembly station there are feed-in rollers which are continuously driven by the motor M1. The feed transport rollers are Lüalzeπ with a smooth surface, to which the paper sheets are pressed in a known manner by means of pressure rollers 5. At the exit of the collating station there are two identically designed output traction rollers 6, which are continuously drivable by a motor M2. The drive of the feed roller 4 and the output roller 6 can also be driven by a common motor with the interposition of toothed belts.

The device according to the invention initially has at least one lower vacuum transport unit 7. However, it is expedient to provide two lower vacuum trap spacers 7 arranged parallel to one another, since - 8th

This can further improve the operating accuracy and operational safety of the device. The two lower vacuum trap parts 7 are arranged outside the paper path E-E and are each assigned to one of the two paper sheet rows R1 or R2. Each of these vacuum transport units 7 has an endless conveyor belt β, which is provided with a profile 20. The conveyor belt 8 is guided over two deflecting rollers 9, 10, from which the deflecting roller 9 can be driven via the schematically indicated motor M3. The motor M3 can at the same time also drive the Umlεπkrαlle 9 dεr zωεitεπ lower vacuum trap sports unit 7 diεneπ. The deflection pulleys 9, 10 are arranged on a support 11 on a support 11. In addition, a vacuum chamber 12 is provided between the two deflecting rollers 9, 10, which is integrated in the carrier 11 in the exemplary embodiment. This vacuum chamber 12 is open to the upper working strand 8a of the conveyor belt 8. The upper working run 8a borders on the

Papierlaufebenε E-E and is only a short distance below this paper running plane.

The vacuum chamber 12 is appropriately divided in its longitudinal direction in order to adapt the device to different shape heights in individual directions 12a, 12b, 12c, which can optionally be connected to a vacuum source 13. Only the middle single chamber 12d can be connected to the vacuum source 13. Each of the individual chambers 12a-12d has a longitudinal slot 14a-1d which is open towards the workstring 8a. - 9 -

Instead of dividing the vacuum chamber 12 into individual chambers, it would also be possible to provide a vacuum chamber that is continuous and has a longitudinal slot that is open toward the working strand 8a. The end regions of the slot may then be closable over a predetermined length as a function of the format height of the respective paper sheets, which are not shown, by πchiεbεr.

As can be seen from FIG. 1, the two ends 11a and 11b of the carrier 11 are arranged offset in the paper running direction P with respect to one another. The ends 11a, 11b can be adjusted independently of one another by means of a setting device 15 and 16, which is expediently designed as a screw spindle extending perpendicular to the paper running direction P and parallel to the paper running direction E-E. The adjustment device 15, 16 can be driven by hand or by means of one each

Stepper motor.

For the second paper sheet row R2, at least one above the paper flow sheet EE is arranged, vacuum suction piece 7 '. Here, too, it is essential to assign the paper sheet row R2 to parallel parallel to the most orderly vacuum transport units 7 '. The upper vacuum transport unit 7 'are designed in the same way as the lower vacuum transport unit 7', therefore the vacuum transport unit 7 ', ^" their component parts and the components interacting with them with the same vacuum and the same transport distance 7 are related Parts, only with the addition of an indent. The above description of the lower one - 1 0 -

Vacuum trap spacing tεπ 7 therefore also applies analogously to the upper vacuum trap spacing 7 '. The upper vacuum transport unit 7 'differs from the lower one only in that the lower strand 8'a of the transport unit 8' forms the working strand in the case of the upper vacuum transport unit 7 'and accordingly the vacuum chamber 12' is open towards the bottom. The lower working run 8'a is adjacent to the pair of runways E-E at a short distance from it.

So that the working strands 8a and 8'a are as close as possible to the bottom or above the paper path, they have to be removed from the paper sheet 1, 2 as little as possible from this paper path, it is appropriate, useful and the lower vacuum trajectory 'To provide a thin Trεππ- plate 17 extending in Papiεrlaufεbeπe. This separating plate 17 guides the two paper sheets 1, 2 ωahrεπd dεs overlap sheets separately from each other and also prevents the upper paper sheet from being sucked by the lower vacuum transport units 7 and the lower paper sheet 7 from the upper paper sheet. The separating plate 17 can also be made of transparent material, such as acrylic or glass, for example, in FIG. 1 and also below the transparent separating plate 17 liεgεndεπ vacuum transport device 7 and the components that can interact with them are. - 1 1 -

So that it is ensured that the respective paper sheet is fed to the associated vacuum sports unit, it is provided in front of the separating plate 17 for each paper sheet row R1, R2 εiπε manual device 18, 18 '. In order to be able to adapt the device to different operating modes, the inlet direction 18a or 18'a of the directional guide 18 is height-adjustable. The two guiding devices 18, 18 'are expediently designed in the manner of a light guide and can be folded independently of one another in the direction of paper travel E-E and perpendicular to the direction of paper travel A pivoting axis A. On this paper, the paper sheets originating from the paper sheet row R1 or R2 can either be to the upper or lower sheet of the sheet plate and the paper sheets of the other paper sheets can be used to the bottom plate 17 in addition to the top plate. üJεπn e.g. If the paper sheet row R1 originating from the paper sheet 1 is to be moved further from the lower vacuum transport unit 7, then the guide device 18, as shown in FIG. 3, is folded upwards. As a result, the paper sheets 1 of the paper sheet sheet R1 are slid into the working strands 8a of the vacuum transport unit 7. For the paper sheet R2, the direction of travel 18 'with its inlet end 18'a is then folded down and this

Papiεrblättεr 2 are thus led to the working strands 8'a of the upper vacuum trap units 7 '. If, in addition, other paper sheets that are not longitudinally cut and their width of the sum of the breadth of the paper sheet 1, 2 corresponds, should be processed, then both wires are pushed towards the end 18, 18 '. - 1 2 -

In order to ensure a precise operation of the device, it is also of Vαrtεil if the driven deflecting deflectors 9, 9 'are provided with V rsprüπgεn 19, 19', which are in corresponding recesses in the associated conveyor belt 8, 8 'εing. The design can be formed, as in the shown embodiment, by means of the perforations 20, 20 'of the conveyor belt 3, 8'. The trapezoidal belts can, however, also be designed in the manner of a timing belt, and the driven deflecting rollers then have corresponding toothing on their U claws.

The Lüirkuπgswεisε of the εrfindungsgεäßεπ device is now first described with reference to the figure π 1 - in a first 3etriεbswεisε. In this operating method, paper sheets 1, 2 derived from dεπ bεidεn paper sheet trisih R1, R2 are used, which is referred to in technical jargon as "2-use slalom operation". Hiεrbεi the sheet of paper 2 avenged in the direction of the paper should be placed over the left sheet of paper 1. Furthermore, the paper blade is symmetrical to the longitudinal εbεπε of the device, which means that it is referred to as a "medium-symmetrical variation". For this purpose, the secondary vacuum paper separators 7 for transporting the paper sheets 1 originating from the left paper sheet row R1 and the upper vacuum transport units 7 'for transporting the paper sheets originating from the right paper sheet row R2 are used for this purpose. The guiding directions 18, 18 'are set as shown in FIG. The lower vacuum transparency 7 are inclined with their ends on the outlet side to the longitudinal center line - 13 -

set, just as the upper vacuum traction ports 7 'in the opposite direction are also inclined with their outlet ends toward the longitudinal-to-the-left ends, as shown in FIGS. 1 and 4.

The paper sheets 1, 2 are conveyed in the paper running direction P by the transport waves 4 of the feed transport. Here, the paper sheet 10 is guided by the guide device 18 to the working stream Ba dεr the lower vacuum transport device 7 and the paper sheet 2 is guided by the guide device 18 'to the working structure 8'a of the upper vacuum transport device 7'. The paper sheet 1 is dominated by the vacuum in the vacuum chamber 12 5, which initially passes through the slot

14a and later also through the slits 14b, 14c and 14d and the perforations 20, is sucked into the working strand 8a and taken over by the continuously running conveyor belt 8. Due to the inclined position of the conveyor belt relative to the longitudinal medium, the paper sheet 1 is moved in the same direction in the paper running direction P and also towards the longitudinal central axis. In a similar manner, the paper sheet 2 is taken over from the working strand 8'a of the conveyor belt 8 'of the upper 5 vacuum transport units 7' and is used to the side in the direction set to the longitudinal direction. Jεdεs paper sheet is only offset by half the paper sheet width. The two sheets of paper are overlaid on the output side of the device g. A kaπteπgeπauεs Überεreiπaπdεr- lεgεπ of the paper sheets 1, 2 can be adjusted by adjusting the vacuum trap unit 7, 7 'by means of the Vrstεlleiπrichtuπgen 16, 16'. - 14 -

The overlapping paper sheets 1, 2 are then captured and transported by the transport omega 6 of the delivery carrier. Wεππ e.g. 5 only after a paper sheet (benefit) of row R1 is to be output, then the upper vacuum transport unit 7 'assigned to the other row R2 and thus the paper sheet 2 recorded by it are briefly stopped. During this time the precursor, e.g. the cutting machine are stopped. As soon as the individual paper sheet 1 has seen the step of the vacuum traverse vacuum 7, the upper vacuum traction unit 7 'and the precursor are started again.

If the left paper sheet 1 is to be placed over the right paper sheet in a similar manner, then the vacuum transport devices are set by means of the first direction 15, 16 corresponding to FIGS. 6 and 7. The guide devices 18, 18 'are also changed over. In this case, the upper vacuum transport devices 7 'then transport the left paper sheet 1 and the lower vacuum transport devices 7 transport the right paper sheets 2.

From FIG. 8 it can be seen how, by setting the lower vacuum trap spacing 7π parallel to the paper running direction P and the upper vacuum transporting unit 7 'obliquely to the paper running direction P diε from the right paper sheet row R2, the paper left-hand row R2 can be offset from the left-hand row R2 The paper sheets 1 coming from the right paper sheet row R1 can only be moved further. In this way - 1 5 -

εiπe P3pierverarbεituπg with "fixed edge left" εromplεπ.

For example, the inclined position of the upper vacuum trap spacing can be achieved with "2-IMutzεπ-Vεrarbεituπg" with "Fixkaπtε right".

FIG. 10 shows an operation with "2-l \ lutzεπ-Koloππεπbεtriεb". The vacuum ports 7 and 7 'are set slightly obliquely outwards. As a result, the first layer of paper in the solvent base is touched 1, 2 in the middle of each other and brought at a spacing that is good for εiπε good Ξtapεlbilduπg of Vαrtεil.

FIG. 11 shows the device in sαgεnaππtεπ "1-I \ lutzeπ operation". In this case, only εiπ paper sheet is processed, which however has the same size as the paper sheets in the previous embodiments. In this case, only the obεrεπ vacuum traction device is used and the uπtεreπ vacuum traction device is used, and the two lines are set either at the bottom or at the bottom only so that they are diabetic.

The device can be operated manually by means of a preprogrammed control, which acts on the device, which is the screwdriver 15, 15 'or 16, 16' vεrbundεπ, actuated.

The Uπtεrtεiluπg of the vacuum chamber 12 or 12 'in your own individual chamber or the cover of the Eπdbε- rεichε dεs slot of a continuous vacuum chamber - 1 6

is required to adapt the device to different format heights. In the case of the smallest shape height of, for example, 75 mm (3 inches), all the individual chambers 12a-12d and 12'a-12'd are connected to the vacuum source 13. In this case, when using slides, the longitudinal slot of the continuous vacuum chamber must be opened to its full length. However, if paper sheets with a larger format height are to be processed, care must be taken to ensure that these paper sheets are only sucked into the traction ports 8, 8 'of the vacuum traction devices 7, 7' when the backing paper sheet is used just leaves. At the exit of the device, the paper sheets must only be sucked onto the conveyor belts 8, 8 'until the front edge of the respective sheet of paper vππ the first transport salt of the output port is detected. In order to ensure this, a larger or larger number of drawing chambers 12a, 12b, 12c and 12'a, 12'b, 12'c, respectively, are formed on the inlet side and on the outlet side of the vacuum transport units 7, 7 'jε depending on the height of the paper sheets The vacuum source 13 is switched off αdεr diε Eπdbεrεichε dεs slot of a through-going vacuum chamber are closed to a greater or lesser length by sliders.
