Description

The invention relates to a collecting and conveying device for collecting and conveying sheet-shaped printed products according to claim 1

State of the art

In print processing companies and publishing houses, printed products are manufactured with a wide variety of requirements and formats. Among other things, printed paper is stacked, aligned, glued, stapled and / or also folded or creased.

In particular, due to the advancing digitization, relatively small batches are often processed. As a result, the number of machine retooling required between the individual batches to adjust it to the next format, and the retooling times of often greater than 30 minutes required, increase relatively sharply. In addition, the constantly increasing costs for the floor space required to set up the necessary devices for processing printed products are becoming more and more important.

task

The invention is based on the object of lowering the operating costs for processing printed products.

The object is achieved on the basis of a device according to the preamble of claim 1 through its characterizing features. Expedient and advantageous developments are specified in the dependent claims.

Accordingly, the invention relates to a collecting and conveying device for collecting and conveying sheet-shaped printed products, preferably unstapled stacks of sheet-shaped printed products, such as. B. paper, in particular flat sheets, cardboard or the like, to a downstream conveyor line and / or to a downstream device further processing the printed products, with a housing and with conveying means for feeding the printed products into the collecting and further conveying device and with further conveying means for their further conveyance . This collecting and further conveying device is characterized in that the further conveying direction of the further conveying means is directed transversely to the conveying direction of the feeding means for the printed products to be collected and conveyed.

A separate floor space for a collecting and further conveying device constructed in this way is not required in a space-saving and thus cost-saving manner. It can be placed directly in the line of a collecting line, e.g. a stapling machine, integrated, if necessary placed on top of it. Instead, for example, a supply of printed products to be processed can be positioned on the production area that is freely available next to the collecting line. For example in the form of a tower shelf, possibly with a delivery unit for delivering loose sheets or flat sheets, in particular in the form of a stack of such loose sheets or flat sheets, to the collecting and further conveying device.

Further advantages of such a collecting and further conveying device for collecting and further conveying sheet-shaped printed products are a possible more compact arrangement and integration in a production line and, consequently, shorter distances for the operating personnel between the individual devices for the production of printed products and thus an overall massive possible reduction the respective pro rata labor costs due to reduced travel and thus time expenditure.

• platzsparend durch Integration mehrerer Verarbeitungsmöglichkeiten von Druckereiprodukten in eine Linie,
• platzsparend durch Übereinander-Anordnung verschiedener Verarbeitungswege,
• zeitsparend beim Einlernen durch einheitliches Bedienkonzept von vorn bis hinten,
• zeitsparend durch automatische Umrüstung (FormatUmstellung) durch Stellmotoren überall,
• vielfältig durch Ausbau der Linie mit zahlreichen unterschiedlichen Verarbeitungs-Optionen.

Because the proportion of labor costs in the bracket price or in the finished printed product is about 10 times as high as the proportion of amortization costs. Constructive measures that reduce labor costs therefore have a comparatively strong effect, as does the reduction in the required floor space for the processing machine or, better, the chain of machines or devices for the production of printed products. Therefore, the advantages of such a collection and further conveying device are listed again:

• space-saving thanks to the integration of several processing options for printed products in one line,
• space-saving thanks to the arrangement of different processing routes,
• time-saving when teaching-in thanks to a uniform operating concept from front to back,
• time-saving thanks to automatic conversion (format conversion) by servomotors everywhere,
• diverse by expanding the line with numerous different processing options.

The collecting and further conveying device for collecting and further conveying sheet-shaped printed products is in particular a deflection unit which changes the conveying direction of an unstapled stack of sheets by preferably 90 ° in the horizontal plane, with the orientation of the stack of sheets remaining the same.

This enables an alternative secondary flow, e.g. coming from a so-called haul-off tower (several cassettes with printed products to be processed, arranged one above the other), in order to smuggle in space-saving transversely to a main transport direction of a printed product processing system (e.g. a saddle stitcher or perfect binder with digifinisher extension). Because this is an advantageous arrangement so that the operator has short distances.

Here it may be necessary to adjust the length and width of the feed and deflection conveyor for the creation of a printed product, e.g. a brochure, on the stack of sheets to be fed in order to ensure the correct guidance and cohesion of the unstapled stack of sheets. This stack must not slide apart and must be exact be transferred centrally and aligned straight into the downstream device, eg a creasing-folding unit. Further details on the collecting and further conveying device in general and in particular on this are described in more detail below.

According to a preferred embodiment, a variable-length adjustable conveyor path for adaptation to different formats of printed products to be collected and conveyed on can be provided for the feed means.

In this way, the conveying length and / or the transfer line from the supply conveying means to the further conveying means can be adapted to different formats and lengths of printed products to be collected and further conveyed. In addition, an adjustment of their distance to the further conveying means is possible, which can be implemented, for example, in the form of a so-called cross belt comprising a transport belt, as described in more detail below. The distance in turn depends, among other things, on the format of the printed products to be processed.

The formats of the collecting and further conveying device for collecting and further conveying sheet-shaped printed products can, for example, be between credit card format and A3.

Particularly preferably, the conveying-side end of the variable-length conveying path is designed to be adjustable in position, in particular with respect to a longitudinal axis running through the further conveying means in the further conveying direction.

As a result, the change in length of the conveyor line can take place directly at the point of transfer and, if necessary, an adaptation to different properties of different printed products can be made possible.

Another advantage is that the position of the inlet or takeover area of the variable-length adjustable conveyor line can remain unchanged. This means that no time-consuming and therefore costly retooling is required when changing formats in this area.

According to a further advantageous embodiment, a variable-position, preferably vibratable stop can be provided for the printed products to be collected and conveyed on, in particular to adapt to different formats of such printed products and / or to align printed products on top of one another.

The jarring of the stop can be generated, for example, by appropriately controlled actuators, e.g. to create a stack with clean edges from the printed products to be collected and conveyed on.

In other words, it is a matter of reversing the direction of the stack of loose sheets on its conveying path. For this purpose, in the collecting and further conveying device or deflection unit, which changes the conveying direction of the unstapled stack of sheets by preferably 90 ° in the horizontal plane, whereby the alignment of the stack of sheets remains the same, an inlet unit is provided at the beginning, which takes over the stack from the outside from the direction of the haul-off tower and conveys it to a stop that can be adjusted depending on the format. Then the further transport of the stack, this time transversely to the infeed direction and thus now parallel to the collecting direction, preferably a collecting chain, is carried out by a transverse conveyor, for example a transverse belt consisting of two parallel transport belts.

The distance between the two transport belts can be adjusted depending on the format. In between there is a grille so that nothing falls through.

During the entry into the deflection unit, the cross belt must be passed over by the stack of printed products to be fed in, without the loose stack of sheets getting stuck between the transport belts of the cross belt or on the pull grate. There is an auxiliary device for this, a so-called bridge slide. It supports the incoming loose stack so that it does not fall between the crossbelt belts on the pull grate underneath, and pulls back before the crossbelt lifts the stack out.

In order to safely lift the stack off the infeed belt, the side of the cross belt that is remote from the feed rises, lifting the stack out of the way and starting to transport it in the direction of further processing (downstream). As soon as the last edge of the loose stack has left the infeed belt, the transverse belt is lowered again, and a further stack can now be fed into the area of the infeed belt while it is being transported towards the downstream device, e.g. the creasing and folding unit , which was "occupied" shortly before.

The cross belt then conveys the stack further, e.g. B. in the creasing-folding unit, the creasing must be done exactly at right angles to the inlet edge, which is controlled by the fact that the two bands of the transverse belt can run at different speeds.

This means that creasing errors can be actively counteracted. For this purpose, it is advantageous if the two transport belts of the transverse belt are as far apart as possible, which is why their spacing is adjustable. As a result, different formats can be processed, especially small formats up to credit card formats.

And because the infeed belt (which comes from the take-off tower) must reach exactly to the infeed, generally speaking to the first or front transport belt of the cross belt, but this is adjustable, the length of the infeed belt must also be adjustable. This is because the position of the start of the infeed conveyor is fixed (invariable) in relation to the housing of the collecting and further conveying device, so that the same takeover or transfer position can always be ensured from the outside in relation to a feed device to be positioned upstream.

Such a transfer position to be docked to the takeover position of the collecting and further conveying device can be implemented, for example, in the form of the end of an inclined elevator that feeds the printed products removed from the haul-off tower and assembled into a loose, unstapled stack.

In order to collide with the downstream edge of the stack, which is pointing downstream in relation to the main flow conveying direction, and which is then the front edge of the stack during the subsequent transverse transport - the orientation of the loose, unstapled stack remains unchanged, only the transport direction is preferably changed by 90 °. So that all sheets or sheets are exactly on top of each other, the stop for the stack is positioned by means of a stopper cylinder.

The two cross belts are driven by servomotors. As a result, they can be switched from one drive direction to the opposite direction and back again in very quick succession. This can be used to repeatedly "push" a stack of sheets fed and deposited thereon against a stop surface that can be positioned according to the format to be conveyed, so that the individual sheets slide together to form a stack with clean edges. So-called stopper cylinders are provided for positioning the stop surface in accordance with the format to be conveyed. Accordingly, so-called side stops can shake the stack on its other two sides. This means that the stack of loose, unstapled printed products to be fed in and on can be jogged together from the front and back as well as from the left and right.

In addition, it is particularly preferred if two drives, in particular servo drives, are provided for the further conveying means, which drive the conveyor belts of the further conveying device on which the further conveying devices Printed products are conveyed further, each drive separately from one another in the further conveying direction.

This means that each of the two transport sides of the printed products to be conveyed can be acted upon individually.

The further conveying means, viewed in the further conveying direction, act on the printed products to be further conveyed in their left and right edge areas, in particular by means of conveyor rollers and / or conveyor belts, preferably from the underside of the printed products and in particular by means of cams provided on the conveyor belts Support of the stack, viewed in the conveying direction, from the rear. These cams can protrude outward from the conveying surface of the respective conveyor belt, that is to say in the case of a circumferential belt upwards on the upper side and downward on the underside, in order to each form a so-called driver for the stack of sheets to be conveyed.

In particular, the two drives of the further conveying means for aligning the printed products to be conveyed further can be designed to be controllable at least temporarily at different speeds and / or with different conveying directions.

This enables the unstapled sheet stacks to be aligned over the shortest distance and in the shortest possible time, for example in milliseconds, in particular due to the high efficiency and accuracy due to the great leverage of the drives on the sheet stacks at their outer areas.

The formation of a stack with clean edges from the printed products to be collected and forwarded has a massive effect on the quality of the end products. This is all the more important if no final cutting of the sides of the finished printed products is provided.

For example, the stacks of printed products to be conveyed on can be delivered to a central conveyor line of a stapling device, e.g. to prepare a folding process preceding a stapling process, in particular a so-called creasing process. For this it is very important that the stacks are precisely aligned and fed with clean edges.

To adapt the onward conveying device to different formats of printed products to be collected and conveyed on, in a further advantageous embodiment the distance between the conveyor rollers and / or conveyor belts can be adjustable for setting the conveying width for the printed products to be conveyed on.

In a particularly preferred embodiment, so-called side stops can also be adjusted to adjust the conveyor width. The distance between the transverse belts should be able to follow this adjustment within a certain, relatively large framework in order, on the one hand, to guarantee the effectiveness of the alignment of the front edge over the two transport belts and, on the other hand, to avoid a stack jamming in the side stops.

To support the printed products to be collected and further conveyed, according to a further embodiment, a support unit for the printed products to be collected and further conveyed can be arranged between the conveyor rollers and / or the conveyor belts, in particular a support unit that is preferably automatically adjustable in width in relation to the further conveying direction.

This facilitates the adaptation / conversion of the further conveying device to different formats of printed products to be collected and conveyed, in particular their automated conversion.

The sides of the support unit facing the conveyor rollers and / or conveyor belts are preferably connected to them, so that when the distance is adjusted, the width of the support unit is also adjusted at the same time.

For this purpose, the support unit can be designed as a support grille, in particular as a variable-width adjustable element, e.g. in the form of several elongated, flat, in particular upright or perpendicular elements, arranged side by side and connected at changing distances, comparable for example to steel rulers. The connections between the individual elements can, for example, alternate between the center and the outside. In this way, a good "accordion effect" can be achieved in terms of width, while at the same time providing high stability for supporting the printed products to be conveyed further and also low resistance in the further conveying direction.

According to a further preferred embodiment, the support unit can be variably adjustable in position, preferably adjustable in height in the further conveying direction, in particular tiltable, preferably together with the conveyor rollers and / or conveyor belts. Particularly preferably, the entire cross belt, including the vibrator, can be rotatably mounted around the drive shaft and can raise its upstream end so far that it protrudes beyond the infeed belt and thus lifts the stack of printed products to be fed and further conveyed that has come to a standstill on it, so that the cross transport can be initiated without the pile of loose sheets getting stuck on the infeed conveyor.

This enables the simultaneous processing of two printed products to be collected and conveyed one after the other. This is done by supporting the second (subsequent) printed product in an elevated position compared to the first, so that the former continues without any influence from the latter, in particular on its alignment and stacking form of the loose and unstapled sheets or sheets, and thus out of the collecting and Further conveying device can be transported away.

The second (subsequent) stack slides on the conveying means for feeding the printed products into the collecting and further conveying device (the infeed) longitudinally above the first (previous) stack on the further conveying means (the transverse belt). The feed means (the infeed lengthways) are extremely narrow and cannot be adjusted in width. The stack entering from the front is only moved to its, in relation to the main conveying direction, which corresponds to the onward conveying direction of the Collecting and further conveying device matches, held upstream side in the inlet lengthways.

The side opposite this with a very large free area covers a large part of the (relatively short) transverse band. For this reason, it is beneficial that the transverse movement is moved quickly to the lower level so that the entry (from the front) from the haul-off tower has enough time, because in the case of the maximum format it takes a correspondingly long time.

For this purpose, the entire cross belt can tilt, including the jogger and stopper cylinder and the pull grate (it rotates a few degrees around the downstream drive shaft), but only for a short time so that the stack does not get stuck on the infeed belt. In return, it lies horizontally in the rest position and at the level below the (always horizontal) infeed conveyor. For lifting, the axis of the downstream (driven) deflection roller stops, and the upstream deflection roller (still behind the cross belt) is raised so far that it is above the level of the infeed conveyor and thus lifts the stack on the infeed conveyor.

For further transport downstream, the upstream side of the transverse belt quickly lowers again as soon as the infeed belt is free. As a result, the second (incoming) stack is higher than the first (running out across it).

This is particularly important in the case of comparatively large dimensions of the printed products to be collected and further conveyed, e.g. B. larger than A5 format, and massively increases the processing speed of the collection and Further conveying device, since during the further conveyance of the former, possibly already during the alignment of a stack on the conveyor rollers and / or the conveyor belts, the second can already be fed into the collecting and further conveying device and collected.

In order to prevent the sheets of the stack from slipping on the conveyor belts when the conveyor belts accelerate rapidly, additional cams are provided on the conveyor belts, which can act on the stack of paper from behind in order to stabilize the transverse transport.

In other words, the first stack runs on the infeed belt (transverse to the main conveying direction of the saddle stitcher) up to the rear stop, is then lifted by the cross belt (more precisely, from its upstream side), then the cross belt begins a movement downstream to the stopper cylinders, that is, to the vibrating station (the stack now moves diagonally downwards), and as soon as the upstream edge of the stack now lying on the transverse belt has left the infeed belt, the transverse belt is lowered again. Then the first stack (on the transverse belt after it has been lowered) is lower than the second one that now follows on the infeed belt, the downstream edge of which can slide over the first (previous one).

In this way, the leading edge of a stack can advantageously be aligned on the transverse belt with two servomotors.

• ein zwei-Ebenen-Konzept, so dass mit einem in der Höhe verstellbaren Gestell am gleichen Platz je nach Bedarf entweder eine 90°-Umlenkeinheit oder ein Überleittisch eingesetzt werden können, wie nachfolgend noch näher erläutert.

In particular, it is advantageous if the device comprises:

• a width-adjustable cross belt and / or
• a length-adjustable inlet and / or
• a bridge carriage and / or
• the use of the cross belt as a vibrator along the transport movement and / or
• the use of (eg servo) motors of the transverse jogger to change the position of a folding groove to be created subsequently (by setting the intended position of the sheet stack asymmetrically), and / or
• a two-level concept, so that either a 90 ° deflection unit or a transfer table can be used with a height-adjustable frame in the same place, as will be explained in more detail below.

In order to be able to reposition the collecting and further conveying device for collecting and further conveying sheet-shaped printed products, it can be arranged in a height-adjustable manner in the housing, e.g. B. to make room for another desired unit to be arranged at this point for processing and / or conveying printed products.

A possible structure for such a repositioning can be, for example, a spindle drive. Such spindle drives can be adjusted comparatively quickly and precisely, e.g. by means of a servo drive, and otherwise do not require any energy to reliably hold the set position. They can also take heavy loads.

Such a unit for processing and / or conveying printed products can be, for example, a pass-through device for passing through and outputting printed products.

Preferably one with a linear transit direction. As a result, if necessary, printed products can also be fed from further locations arranged in a straight line upstream of the housing to the locations arranged downstream of the housing of the collecting and further conveying device for collecting and further conveying sheet-shaped printed products.

This pass-through device can also be arranged in the housing for this purpose and can be positioned so that it outputs printed products to be passed through preferably to the same output point as the collecting and further conveying device for collecting and further conveying sheet-shaped printed products.

For this purpose, the pass-through device for the pass-through and output of printed products can also be arranged in a height-adjustable manner in the housing. Preferably also by means of a spindle drive. As a result, if necessary, that unit, i.e. the collecting and further conveying device for collecting and further conveying sheet-shaped printed products or the transfer device, can be positioned at the position in the housing that is intended for the output of the relevant printed products.

The collecting and further conveying device for collecting and further conveying sheet-shaped printed products or deflecting unit must also be fed. For this purpose, from the paper flow upstream in the collecting direction, preferably a collecting chain, for example a folding machine (for individual folded sheets or single sheets) and transversely to the collecting direction, for example a haul-off tower for loose stacks or single sheets can be connected.

In this way, sheets, folded sheets or stacks of sheets can be fed in by means of the deflecting unit which can be integrated into the plane of the collective flow and removed from it again - with unchanged sheet orientation.

The deflection unit thus enables cross-feeding of printed products, e.g. B. from a take-off tower, because this is designed to feed transversely, so from the side to the chain transport direction, sheet stacks in the further processing machine. And for this, the transport direction of the sheets and / or stacks must be deflected, but not their alignment.

If, however, instead of the collecting and further conveying device for collecting and further conveying sheet-shaped printed products or deflecting device upstream of the main conveying direction, e.g. another folding machine is to be operated, the deflecting unit would be in the way of this upstream device, in order to transfer printed products on the direct path downstream, for example to a arranged there device, such as a creasing-folding unit to be able to promote. Therefore, the above-mentioned structures are provided for such repositioning, such as raising or lowering, for example spindle drives.

So it can be turned up or down and thus cleared out of the way and in its place another device, such as. B. a transfer table to be positioned by the upstream device, such as a folding machine, a Folded sheet or from a roll cutter or from a large format feeder to transfer a single sheet to the creasing-folding unit. If printed products from the tower are then to be processed again, the repositioning of the collecting and further conveying device just described for collecting and further conveying sheet-shaped printed products or deflecting device and, for example, transfer table is carried out in reverse order.

Preferably, both the 90 ° deflection unit and the transfer table arranged underneath can be arranged in an upper frame (stage) of the housing, which can be adjusted in height relative to a base frame by means of four spindle drives, so that either the deflection unit or the transfer table is on the height of the downstream part of the paper converting machine (preferably a crease-crease unit).

The 90 ° deflection unit and the transfer table can preferably move up and down at the same time. This means that only one adjustment process is necessary. The lower position is selected for the deflection unit and the upper position for the transfer table, but it could also work the other way around. However, the transfer table is much flatter, so it is at the bottom. But because the transfer table is installed very flat (i.e. cramped) and because in practice you have to have access to it, e.g. because you have to clear a paper jam, the deflection unit above is preferably installed in an upper platform, i.e. in a frame opposite the one the stage can be raised again. Then the transfer table gets air above it and the operator has access to it.

Lifting axes or spindles can also preferably be provided for this lifting of the upper stage (= moving the "through-feed unit").

Accordingly, according to a further preferred embodiment, it can be provided that the collecting and further conveying device for collecting and further conveying sheet-shaped printed products is designed to be height-adjustable in relation to the transfer device for transferring and dispensing printed products in the housing and / or that the transfer device for transferring and dispensing printed products is opposite the collecting and further conveying device for collecting and further conveying sheet-shaped printed products in the housing is designed to be height-adjustable.

In any case, short, time-saving and thus cost-saving routes are retained for the operating personnel.

by way of example, a perspective view of a collecting and further conveying device, arranged together with a transfer device in a housing.

Accordingly, the Figure 1 a collecting and conveying device 1 for collecting and conveying sheet-shaped printed products 5. The printed products are preferably in the form of unstapled stacks of sheet-shaped printed products, such as. B. paper, especially flat sheets, cardboard or the like. These are conveyed to a downstream conveyor line and / or to a device which processes the printed products further downstream.

These unstapled stacks of sheet-shaped printed products can originate, for example, from an upstream intermediate store and be composed of, in particular, separately stored, different individual sheets. This Intermediate storage can be designed, for example, in a so-called tower (tower storage) with a large number of individual, preferably one above the other, partial storage (compartments). Loose sheets to be joined together to form a booklet or brochure can be temporarily stored therein, a set of sheets to be joined can be removed per machine cycle, combined into a stack and fed to the collecting and further conveying device 1.

The collecting and further conveying device 1 is in a housing 2 (see Fig. Fig. 6 ) and has feed means 3 for feeding the printed products 5 into the collecting and further conveying device 1 and further conveying means 4 for their further conveyance.

The further conveying direction 4.1 of the further conveying means 4 is directed transversely to the conveying direction 3.1 of the feeding means 3 for the printed products 5 to be collected and conveyed.

In the case of the conveying means 3, a variable length adjustable conveying path 3.2 is provided for adapting to different formats of printed products 5 to be collected and conveyed further (e.g. from credit card size to A3).

The length variability of the conveyor line 3.2 can be achieved by one or more, e.g. B. two deflected conveyor belts 3.4 are effected, the distance between two deflection rollers 3.5, 3.6 at the opposite ends of the conveyor line 3.2 is variable, in that at least the deflection roller 3.5 closer to the further conveying means 4 is displaceable. For example, a telescopic holder can be provided between the two end pulleys 3.5, 3.6.

The roller 3.5 must give way to the belt 4.3 closely (cross belt becomes wider) or follow (cross belt becomes narrower), i.e. it must be adjustable.

For the necessary length compensation of the conveyor belts 3.4, there are further deflection rollers 3.7, 3.8, 3.9, 3.10, of which at least one is also arranged to be adjustable. The roles 3.6, 3.8, 3.9 and 3.10 preferably remain fixed. For the conveying section 3.2 shown, the deflection rollers 3.5 and 3.6 form two end-side deflection rollers. Of the other pulleys, the two pulleys 3.7 and 3.9, which are each located in a loop of the conveyor belt 3.4, are able to achieve length compensation for the corresponding conveyor belt 3.4 when the conveyor line 3.2 is adjusted by vertical adjustment. Alternatively, with a suitable tape guide, not shown, the length compensation can also take place by horizontal displacement of a deflection roller in a corresponding tape loop.

The conveyor-side end 3.3 of the variable-length conveyor section 3.2 (see Sect. Figure 2 ) is designed to be position-adjustable, in particular with respect to a longitudinal axis 4.10 running through the further conveying means in the further conveying direction 4.1.

For the printed products 5 to be collected and conveyed on, a stop 6, which can be adjusted in a variable position, is preferably designed to be vibratable, is provided. This serves in particular to adapt to different formats of such printed products 5 and / or for alignment superimposed printed products 5 to one another, for example to form a stack with clean / smooth edges.

For the further funding 4, two drives 4.2; 4.2 'are provided, in particular servo drives, which drive the sides of the printed products 5 to be further conveyed separately from one another in the further conveying direction 4.1, so that the stack can rotate very easily and its front edge is thereby aligned.

Viewed in the further conveying direction 4.1, for the further conveyance of the printed products 5 to be further conveyed, conveyor rollers and / or conveyor belts 4.3; 4.3 'for the further conveying means 4 on the printed products 5, in the illustrated embodiment from the underside of the printed products 5. In order to prevent the sheets of the stack from slipping in the event of strong acceleration, additional cams are provided on the conveyor belts, which can act from behind to support the stack of paper. Such cams are in the figures on the downstream side of the conveyor belts 4.3; 4.3 ', protruding from the respective band.

In Figure 2 the collecting and further conveying device 1 is shown, for a better overview, without sheet-shaped printed products 5 to be collected and further conveyed.

The two drives 4.2; 4.

The distance 4.4 between the conveyor rollers and / or conveyor belts 4.3; 4.3 'is adjustable for setting the conveyor width for the printed products 5 to be collected and further conveyed, for example by means of the in Figure 3 visible drive spindle 4.5 and supported and guided by two non-visible linear axes to the left and right of the drive spindle 4.5. The small rails 4.6 in Figure 3 serve to support the support plates 7.1.

The respective drives for setting the distance 4.4 between the conveyor rollers and / or conveyor belts 4.3, 4.3 'and for positioning and / or shaking the stops 6, 6' are shown in FIG Figure 3 omitted.

This in order to make further details visible, such as further components of the feed means 3, in particular those mechanics required for the length-variable adjustment of their conveying path 3.2, as well as a drive spindle 4.5.

Also not shown therein are the components of one in the Fig. 1 and 2 shown stop 6, 6 'for the to be collected and further conveyed printed products 5. Cf. also the Fig. 4 and 5 .

Between the conveyor rollers and / or the conveyor belts 4.3; 4.3 ', a support unit 7 is arranged for the printed products 5 to be collected and conveyed on. This support unit 7 can, in relation to the onward conveying direction 4.1, be adjustable in its width, as symbolized by the double arrow.

The support unit 7 is designed as a support draw grid, in particular as a support draw grid that is adjustable in width.

The support unit 7, that is to say the drawn grid 7, is fastened with one side to the housing of the belt 4.3 and with the other side to the housing of the belt 4.3 '. When tilting the entire cross belt, it remains parallel to the transport belt. When the belts 4.3 and 4.3 'move apart, it pulls apart.

The entire transverse belt 4 including the vibrator is rotatably mounted around the front, downstream drive shaft and can raise its upstream end so far that it protrudes beyond the infeed belt 3 and thus lifts the stack that has come to rest on it, so that the transverse transport (in the main transport direction 4.10) is initiated without the stack of loose sheets getting stuck on the infeed belt 3. In Figure 1 is the cross belt raised, in Figure 2 it is lowered.

As in Figure 6 As shown, the collecting and further conveying device 1 for collecting and further conveying sheet-shaped printed products 5 in the housing 2 is arranged in a height-adjustable manner. Spindle drives 1.1 are used for this in this version.
