Method for operating a collecting device for printed products according to the preamble of claim 1.

State of the art

Out EP 1 578 614 B1 A process for the production of addressee-specific printed products has become known. In this method, to complete a respective printed product, a plurality of signatures are formed to form the insides of the finished printed product, provided with a cover sheet, and then stapled or bound. An EDP-supported database structure ensures that targeted information is assigned to the respective addressee of the relevant printed product. At least one of the signatures produces an addressee-specific printed product by attaching address-specific information at at least one predetermined location. In this publication, a production of addressee-specific media is followed, each of which has static information that is identical for a variety of media, and which are processed separately from dynamic for each medium different information.

Out EP 0 588 764 A an apparatus and a method for processing printed products has become known, in which the device has a drum-shaped conveying member, which is divided into a plurality of receiving pockets, which have closing and opening positions sectorally. By means of a first feed station, an envelope, fold forward, is fed to the receiving pockets in each case. The envelope is in a holding position of the receiving pockets by an undershot conveying region of the rotating about a horizontal axis conveying member transported to a second feed station. Before reaching this second feed station, the receiving pockets are opened with the envelope placed therein, so that the envelope can be shipped with the collated sheet.

Thus, various methods for collecting printed products have become known in which the printed products are collected on a collecting line. The individual sheets or supplements are each provided by investors, then deducted, and finally handed over to the collection line. The collecting line is known to comprise conveying means, e.g. Conveyor belts, which transport the printed sheets removed for further processing.

The European patent application EP 0588764 discloses a device for summarizing printed products, which means on the one hand from a loading station for the introduction of envelopes resp. Mantelproducts consists in a rotating conveyor organ, and on the other hand from a feed station for the insertion of supplements, so of printed sheets, in envelopes. The end products thus formed are removed from a removal station from the rotating organ and transported to a further processing machine.

When collecting printed sheets, the aspect of handling errors that occur when printing sheets are removed is particularly important because it greatly affects the quality or processing time of a collection of press sheets used to make a final product. Therefore, error handling is an essential aspect of such a collection process.

In some existing processes, defective products are rejected, the term "product" in the context of the present invention meaning a collection of printed sheets and the term "defective" indicating an incomplete product composition. The disadvantage of such processes is the high waste rate, since the discharged products can not be recycled in most cases.

A further development is the European patent application EP 2 107 023 which discloses a method and apparatus for conveying sheet products. In this case, defective products are not discharged as before, but brought by means of a revolving conveyor back into the collection line, completed there and then fed to further processing. The disadvantage This solution lies in the complicated return transport of faulty end products, which makes the system more expensive.

Basically, one could imagine a logistics in which additional delivery points are provided, which intervene when the removal of the printed products on the ordinary delivery points produce dropouts. Only in such a configuration should at least as many substitute delivery points be provided, this according to the number of operative orderly delivery points. But this would not have covered all eventualities, because even a replacement point provided for the repair process could, in the extreme case, fail, whereby the package would have to be finally sorted out as incomplete. So even such a state of the art solution does not offer a sustainable repair process.

Out CH 701 213 A1 shows an arrangement in which at least two feed stations, the receiving elements are equipped with printed products, which is given the possibility that each feeding station each Aufnahmeefement is equipped with a corresponding Druckereiprodukt. However, it is also possible for only one of the two feed stations to load each receiving element moved past it with a printed product and to deactivate the other feed station during this operating phase. This publication offers the possibility that the upstream feed station to equip each second moving past her receiving element with a printed product and the downstream immediately downstream feed station to equip the remaining receiving elements each with a printed product. Two independent collection lines for the provision of subpackages are not part of this document.

EP 2 30 1 874 A1 describes a method designed for collecting printed products. In this method, the printed products are removed from a stack and stored on a first transport device. The printed products withdrawn from a first feeder are deposited on a first transport device or transferred directly to a second transport device, wherein these printed products are subjected to at least one processing at any point within the second transport device, and the printed products are transferred to the first transport device after the processing has been completed. Furthermore, it should be emphasized that the first and the second transport device work in parallel with one another, ie not in the sense of two independent collection lines each for the provision of subpackets.

WO 2009/015503 A1 deals with the basic structure and the production of groups of printed products. Described here is also a troubleshooting due to feed errors. Thus, if a print product is not delivered to a group at a feed location because a picker is empty, the feed steps at the following feed locations are suppressed and the group is returned with the feed pass being suppressed at all feed locations upstream of the defect on the second pass ,

Presentation of the invention

The invention aims to remedy this situation. The invention, as characterized in the claims, the object of the invention is a method for collecting at least one main product, which is combined with at least one precursor, the main product and / or precursor are supplemented with other supplements, said printed products then together to form a final product.

For this purpose, the main product (hereinafter referred to briefly as HP) and intermediate product (hereinafter referred to simply VP) withdrawn in succession from successive investors and stored on a collecting line on top of each other, and so as a stack of at least two printed products in a receiving pocket of the inserting machine ( hereinafter referred to as ESM for short). Sometimes these two printed products can form a final product, but in most cases this will be a partial end product.

As a rule, the precursor VP is drawn first, then the main product is stacked on top. However, this order is not mandatory. This order applies whenever the precursor forms the front page of the final product.

It is also readily possible to provide removal of several different printed products along this collection line, which are stored one above the other after a certain stacking. This means that basically several VP's can be pulled one after another before the HP or HP's are refilled.

The receiving pockets have holding devices which prevent falling out of the superimposed printed products, in particular when the ESM is a preferably rotating conveying member. The following is based on a rotating promotion, such an embodiment is not to be understood exclusively. It can also provide conveyor organs, which are largely based on a Wegtranslation.

Substantially diametrically opposed to this first collection line for the delivery of HP's and VP's offset in a rotating conveyor member a second collection route is effective, which fulfills the function to form sheet packages, and then they clock in the vorbeidrehenden with said products HP and VP already to introduce loaded receiving bags.

The formation of signature packages is accomplished by a product dispenser equipped with at least one feeder. As a rule, however, the collection section here has a number of adjacent investors, from which one printing sheet is usually deducted. Such a printed sheet package in combination with the products HP and VP then together form the end product, which is then removed from the conveying member and passed on for further processing.

Thus, there is a tactual interdependence between the formation of the HP and VP partial end product from the first collection section and the formation of the entire sheet stack from the second collection section.

The preferably arranged between the two collection lines rotary conveyor organ usually rotates at a monotone peripheral speed, which is designed for the cycle time of the stacked printed products along the two collection lines. In the following, this clock interdependence is also referred to as a clock period.

The print sheet packages are introduced at a transfer point in a receiving pocket, where they are integrated into the already existing HP's and VP's. For this purpose, the HP's and VP's are opened according to their intended use with the aid of an opening device and are then ready to receive the sheet of printing paper. The end product thus produced, which now consists of at least one HP, a VP and a printed sheet, is further rotated by a partial revolution within the rotation of the conveying member before it is detected at a suitable location by a gripper of a delivery chain removed from the receiving bag and transported for further processing ,

The method according to the invention thus opens up the possibility of supplementing the HPs on their collecting route with at least one VP, which is designed as a title page and is particularly effective for advertising. Depending on the number of investors along this collection route, different, customer-specific combinations of HPs and VPs are possible.

As a rule, the CP is first deducted and stored on the collection line; From the next investor then a HP is deducted and stacked on the VP.

Optionally, the VP can be provided as an advertising insert to improve the adhesion in combination with the HP, in a known manner with a punctual glue strip. However, a sufficiently large adhesion can also be achieved on the basis of a conceptually designed surface tension between the two printed products.

If, during stacking, the fixing of the various printed products along the first and / or second collection line is carried out using a gluing, the following possibilities arise, gluing being understood as meaning a local glue application: at least one printed product along the first collection line and / or at least one Printing sheet along the second collection line is (are) provided with a surface-effective gluing. This can be in any order a gluing of a previously drawn print product for fixing a subsequently stacked on it Accomplish print product. The stacking maxim for glued printed products will then be: First, the surface-effective gluing operation is carried out, then the stack-wise dressing is then carried out. Attachment of the respective drawn printed product made.

Thus, the method according to the invention offers the possibility on the one hand of combining different HPs with different VPs within a first collection link, on the other hand to supplement these HPs and / or VPs with different signature packages from a second collection link, resulting in end products which are assembled differently "on demand" can

For this purpose, a higher-level control is provided, which is able to combine the combinations of the different HP's with the different VP's, and to supplement these with different printed sheet packages to final products, which are then available for distribution and customer-specific.

The productivity of such intrinsically complex system via two interdependent collecting links for conveying different printed products depends on the extent to which it is possible to integrate a "repair system", which always intervenes when a so-called "repair process" is pending, i. in other words, whenever errors occur during the product delivery process within the investors along the collection route, resulting in an incomplete end product.

In the case of a product dispenser consisting of a number of feeders, in certain constellations, a missing print of a printed product, be it an HP, VP or a printed sheet, can occur, so that the end product to be created at the final transfer location is incomplete, thus for quality reasons must be eliminated.

Therefore, when it comes to completing the incomplete end product with missing printed products in continuous operation, the following "basic" repair patterns result in principle during operation of the method:
First, according to the invention, it is a matter of proposing a "repair process", which involves feeding the printed sheets from an assembly line of an incomplete set of printed sheets from the other collection line into a complete subdivision of HP and / or VP must be taken into account in a structured order of the sheet.

In such a case, the missing or missing sheets are simply replenished in a clock-conforming manner during a subsequent revolution by sequentially withdrawing only those sheets which are missing from the incomplete sheet set during such a cycle, so that the incompletely loaded receiving bag in question can be loaded in a clock-compliant manner, ie at the same time, at the transfer point.

Thus, when the receiving bag loaded with an incomplete end product rotates past the transfer point, the missing sheets that have now been removed and provided are inserted into the pocket, where they ensure the completion of the final product.

Of course, the subsequent receiving bag, as far as complete printed products have been delivered, now properly loaded.

Only when the end product is complete, its removal is initiated by the controller from the corresponding receiving pocket.

If at most after an initial "repair process" still an incomplete end product before, so still no removal is initiated, and the relevant incomplete loaded receiving bag sent from another revolution, in which the renewed "repair process" is initiated

Secondly, according to the invention, there is a "repair process" in which, due to incomplete removal of the printed products, the structuring of the final product is to be retained, ie the stacked order of the various printed products must have the predetermined order in the end product.

Also in this case, it is initially assumed that the HP's and VP's have been placed in order in the appropriate pocket. If this is not the case, it is already intervened by initially leaving the receiving pocket empty. In such a constellation, there is no removal of the printed sheets, so that the receiving pocket is sent completely empty to a further revolution. The superordinate control also ensures that errors when removing the printed sheets are absorbed in such a way that the pre-fixed sequence of the printed sheet package is retained in any case. So if, for example, the third sheet can not be deducted, the subsequent sheets are targeted also not deducted. Only at a next revolution of the conveying member, the removal of the missing sheet is introduced in order. In the interim phase until the repairing process is completed, the HP's and VP's are highest provided with those signatures having a sequential order

This means, for example, that if, for example, the first printed sheet can not be pulled off, the relevant receiving pocket is initially loaded with no further printed sheets. This receiving pocket must then be operated at the next revolution, that is generally at the next period of the rotating organ.

Now it may happen that the loading of the receiving pocket with HP's and VP's is not fully done, so that this has a direct effect on the release of the sheet set. Here, the same procedure is followed as above, when it comes to ensuring the structured order of the printed products. Thus, if primarily the deduction of a VP should take place, and this does not take place, the deduction of the HP is initially prevented. Thus, an empty receiving bag is set in circulation, which is now not loaded with a sheet package. Only when this pickup bag could be neatly loaded with a HP and VP, command goes to the product dispenser to provide the appropriate sheet for loading this pickup bag.

If complete loading of the bag with inserts can not be done, it will not be emptied and it will be re-circulated until the printing of the missing signature has taken place and the corresponding receiving bag can now be fully loaded.

The essential advantage of the invention is to be seen in the fact that even with multiple collection routes can be dispensed with a complicated return transport of the defective end products, and that the "repair operations" made form an integral part of the product composition.

Selected embodiments of the invention will become apparent from the dependent claims and will be explained in detail in the following description with the aid of the figures and examples described below.

Ways to carry out the invention, industrial usability

Fig. 1 shows a collecting device for carrying out the inventive method. The plant comprises in the figure on the left a collection line 21 for printed sheet 27 on the right side another collection line 30 is provided, in which at least one main product HP and a precursor VP are stacked. In between acts a rotating conveyor member 20, which consists here for example of 12 receiving pockets 22, and which rotates with the direction indicated by arrow 25 direction. The receiving pockets 22 are formed for the continuous formation of main products.

The collection line 21 comprises a conveying means, which in the present case consists of an endlessly running conveyor belt, which of course can also be formed from a plurality of conveyor belts operating in operative connection with each other. The conveyor belt has, in the direction of transport T, a specific speed coordinated with the approach of the remaining printed products and with the rotational speed of the conveyor element 20.

Furthermore, the collection line comprises a number of dispensers A, B, C, D, E, which are designed in particular as a feeder. The investors A-E have the task of the deducted sheet within a certain clock period at a delivery point on the conveyor belt 21 store. This ensures that the forwarding of the printed sheet packet formed along the collecting line takes place in conformity with the clock.

The clock period is thus understood below as the period of time, which ensures the formation of the corresponding printed products packages based on their merger in the conveying member 20.

In the present example, therefore, a specific package consisting of printed sheet 27 is formed along the collection line 21, while a printed product package HP, VP is usually likewise stacked in the same time period along the other collection line 30. The packets thus formed subsequently pass within the rotation of the conveying member 20 to a transfer point 1, where the end product is assembled.

For example Fig. 1 shows that the merging of the two said packages, which have been formed along the collecting lines 21 and 30 to form a finished product, takes place at the receiving pocket no. 9, wherein the printed product packages HP and VP from their transfer point at receiving pocket 1 then a revolution of 240 ° have performed.

The rotating conveyor member 20 now rotates the final product thus formed until it is subsequently taken out at a suitable location by a gripper 28 of a delivery chain 24 from the respective receiving pocket and further transported for further processing 23.

In this case, the rotational speed of the rotating conveyor member 20 is synchronized with the speeds of the two conveying means 21 and 30 so that during a clock period at most a single end product per receiving pocket 22 is formed at the transfer point 1. In other words, the clock period forms a period of time during which a synchronized combination of different subpackets and the transfer of the end product takes place.

For this purpose, the feeders AE along the collecting line 21, the feeders HP and VP along the collecting line 30, the rotating conveyor 20 and the grippers 28 of the delivery chain 24 are controlled by a controller 29 and are equipped to provide continuous status information to the controller 29 can pass on for further processing. This will be explained in more detail in connection with the explanation of a "repair" in the case of faulty removal.

In case of an error, i. in the event that one or more of the investors A-E resp. HP and VP do not deduct any printed product, the end product as such is incomplete and therefore defective.

In such a case, the controller ensures that the defective end product thus formed is not passed on by the conveying member 20, but is initially maintained in circulation. Furthermore, it is prevented that the gripper 28 can pull the defective end product out of the receiving pocket 22. This can be done either by the fact that the gripping function of the gripper 28 with respect to the defective end product does not come into operation or by the fact that the defective end product is pulled so far into the interior of the receiving pocket 22, so that the gripper 28 then reaches into the void. These two options make it possible to use different existing grippers or conveyor organ systems. For example For example, the second alternative can be used if the delivery chain 24 has no controllable gripping function. Of course, further, not described here ways to remove or prevent the removal of a final product possible. In the present embodiment, therefore, the incomplete end product will remain in the receiving member 22 after further removal in the conveying member 20 for a further circulation, wherein a holding device ensures that the product can not fall out of pocket. These processes are under Fig. 2 to 5 explained in more detail.

The collection of a main product HP and a pre-product VP from the respective investors HP and VP is fundamentally the same as for the investors AE. In principle, a multiplicity of investors for main products VP and / or intermediate products VP can be provided along the collection route 30. The here in Fig. 2 The illustration shown assumes that the precursor VP is pulled first, and then the main product VP is stacked thereon. The major product 31 will then carry the precursor HP above, which precursor VP will form the title side of the final product in the context of the further transport underlying herein.

Fig. 2 shows a side view of a first exemplary embodiment of a rotating conveyor member 20 with receiving pockets 22. The partial view "X" denotes a detail of a receiving pocket 22 of the conveyor member 20, which in Fig. 3 is shown enlarged. Here, for example, it is shown that the receiving pocket 22 is loaded with a printed sheet 27, a holding device 26 includes, which is designed as a flap and presses the sheet 27 against a boundary wall of the receiving pocket 22, as soon as it is fully inserted into the receiving pocket 22. Of course, the receiving pocket 22 may be loaded with the same functionality with a sheet package or other printed matter

Fig. 4 shows analogously to Fig. 2 a side view of a second exemplary embodiment of a conveying member 20 with receiving pockets 22. The partial view "Y" denotes a detail of a receiving pocket of the conveying member 20, which receiving pocket in Fig. 5 is shown enlarged. Here, for example, it is shown that the receiving pocket 22 is loaded with a printed sheet 27, a holding device 26 includes, which is designed as a flap and pushes the sheet 27 against a boundary wall of the receiving pocket 22 as soon as it has found completely in the receiving pocket 22 space. Of course, the receiving bag 22 be loaded with the same functionality with a sheet package or other printed matter.

Fig. 6 shows a graphical representation of the "repair process" with the inclusion of the two collection lines 21 and 30. In this FIG. 6 it is based on a number of incidents which may result in the end product being incomplete and therefore can not be removed from the respective receptacle and, as a result, the "repair process" must intervene. This should be designed so that the timing of the rotating member 20 is not affected thereby. In the figure, the voids forming thereby in the receiving pocket are symbolized by "Y".

In this "repair process", the sequence-related structuring of the printed sheets 27 from the investors AE is initially not in the foreground. On the other hand, it is indispensable that the sequence-ordered structuring of the printed products HP and VP is not lost, in particular if it is provided that the precursor VP should form the title page. So on the one hand, it is emphasized here that the printed sheets 27 from the investors AE must be present as a package, on the other hand, the structured package formation in the printed products HP and VP is indispensable. If a structured package formation is to be sought for the printed sheet 27, then in this regard, the Fig. 7 directed.

Thus, if the one or more missing sheet of a sheet package are simply re-supplied, the dispenser formed by the feeder AE will deliver only those sheets during a subsequent cycle cycle, which missing the incomplete sheet set in a receiving bag "stand by". So if the receiving bag loaded with an incomplete sheet package at its transfer point (See Fig. 1 , Pos. 1) again rotated, the now deducted and provided missing sheets are introduced into this receiving pocket. Of course, the subsequent receiving pocket is properly loaded in time with the completely withdrawn sheet. If the printed sheets are present in their entirety, the removal of the end product from the rotating member 20 via the means 24/28 is no longer an obstacle, provided that the printed products HP and VP have also been neatly and completely stripped off.

If, however, after the first completed "repair process" is still an incomplete end product before, so is still no release released, and the Receiving bag can then be completed in the manner described in the next round only.

The Fig. 6 shows the "repair process" of some selected examples, which, mutatis mutandis, also applies to other error occurrences.

Here are related to Fig. 6 the following clarifications are needed:
The left columns AE, which belong to the collection line 21, refer to the conveying member 20, whose one revolution is symbolized by the number of receiving pockets. Of course, the here assumed pocket count of 12 can vary. However, this does not change the basic principle.

Assumed here is a loading of the receiving pockets 22 during three consecutive revolutions, which are marked accordingly with the number of superscript strokes. The dispenser, which is equipped here with, for example, five investors AE pulls for each loaded receiving pocket 22 in order the five sheets a ₁ b ₁ , c ₁ , d ₁ , e ₁ , which then deliver a sheet set to the transfer point.

At the same time, in the other collecting route 30, the procedure is analog, so that the printed products VP and HP are drawn in succession. If no errors occur, the system is designed to be repetitive.

However, it may happen that no printed matter is or can be withdrawn from a feeder, be it along the collection line 21 or 30 (see letter "X" in the figure), so that the package formation is incomplete for the pocket present in the bag, wherein the resulting voids in the receiving pocket are denoted by "Y".

Such constellations go out Fig. 6 out.

At the third clock of the first rotation, no delivery is made from the feeder for the product VP. Insofar as this product is to form the front page of the final product, the consequence of such an error is that the product HP lying thereon is not actively withdrawn, and consequently also actively intervenes on the investors AE, which receive command from the control, no printed sheets to deliver (in the figure with "0" marked), if these in an interdependence to the main product HP not supplied. The consequence here is that the respective receiving pocket initially remains completely empty and is sent to the next revolution.

The FIG. 6 Now shows how such a "repair" comes about. In the next turn, referring to the empty storage bag, which is marked with a raised line, all investors are now active. If all print products can be pulled properly, this receiving bag can be loaded properly and the error can be eliminated without a scrap. If not, then you have to send this bag again in the next turn.

How to proceed when a sheet from the investors A, B, C, D, E is not deducted, it is apparent from the fifth clock of the first revolution. This is about the sheet e ₅ , which could not be pulled. As far as the other sheets can be neatly taught by the collection section 30, the receiving pocket with the drawn sheet, so a ₅ , b ₅ , c ₅ , d ₅ , be loaded, but it must be sent to another revolution.

At the following clock no HP and VP are drawn, meanwhile, the previously failed provision of the sheet e _{5 is made up} for the next revolution, as is apparent from the fifth clock in the second revolution, in which the already printed products are no longer deducted ,

At the seventh stroke of the first revolution, it is true that while the printed product VP _{7 is} torn properly, the other printed product HP ₇ is not. Since the sheets from the collection line AE are interdependent with this unpublished HP product, the controller intervenes and orders that the sheet holder be preconcerted to deliver sheets, which will not strip the entire sheet package. Also in this case, this receiving bag is sent to another revolution. In FIG. 6 It can now be seen that in the next revolution (7 ") all printed sheets a ₇ to e _{7 are} removed after it has been recognized that the missing printed product HP _{7 could} now be neatly taught.

The ninth bar of the first turn (9 ') indicates a possibility, which is always available when it comes to intermediary a specific and to provide targeted reduction of the sheet set. In such a case, only the predetermined signatures are drawn. Conversely, it is readily possible to expand the collection route 30 for the other printed products HP, VP so that several such printed products HP's and VP's can be drawn for individual end products.

At the first clock of the second revolution, it may happen that an error occurs that has already occurred previously (clock three of the first revolution). In such a case, the controller intervenes either by sending a first warning message to the operator or by switching off the operation for checking, depending on how seriously the error is assessed. In Fig. 6 It is assumed that the error in the third turn proves to be non-recurring, in that all printed matter could be properly deducted.

In Fig. 7 The aim is to show how a "repair" with deduction errors in terms of the sheets within the collection section 21 proceeds, so when it comes to ensuring a sequence-wise structuring of the sheet set. The FIG. 7 Thus focuses the provision of the printed sheet from the collection line 21, wherein the sequence-wise structuring of the other printed products from the collection section 30 already in Fig. 6 was treated. For those from the Fig. 7 Resulting operational states "X", "0" and "Y" are explained in the explanations below Fig. 6 directed.

For this purpose intervenes at each error occurring, ie at each unsuccessful removal of a sheet, in turn, the controller, but which is now programmed so that it intervenes when subtracting the subsequent sheet to be delivered so that during the current cycle in a failed Peel off a sheet, the immediately following investors also deliver no more sheets. The recording pocket associated with this clock is therefore only loaded with the print sheets drawn off in succession, which corresponds to the order of the feeders until the failed delivery. If, for example, the first printed sheet can not be pulled off, then there is initially no single printed sheet for loading for the relevant receiving pocket. This receiving pocket must then be operated during the next revolution of the rotating conveyor member.

Now it can happen that after the first "repair" the missing printed sheets can not be deducted in turn completely. Also in this case, the controller will inhibit the stripping of the downstream print sheets within the current cycle, and the print sheets not yet removed will then be replenished on the next rotation. With this approach, it is ensured that the order-based structuring of the printed sheets in the final product is always present, regardless of the number of stacked printed sheets and regardless of how many "repair operations" must be controlled.

Fig. 7 shows selected examples for this "repair process". As can be seen, all printed sheets are properly withdrawn from the corresponding investors at the first clock, so they can be forwarded as a complete sheet set. If now at clock 3 on the occasion of the first revolution of the sheet c ₃ can not be deducted faulty, then immediately thereafter, controlled accordingly, no removal of the remaining sheet d ₃ and e ₃ , even if the deduction could proceed properly. In the following rotation, the missing printed sheets cd and e are then removed as a continuous sub-package and introduced into the corresponding receiving pocket. Since there are two inherently structured subpackets, namely (a, b) and (c, d, e), the merge corresponds to the originally specified order.

At the 4th stroke of the first revolution, for example, the supplement (sheet) b ₄ can not be deducted from the investor B. The controller immediately intervenes and inhibits the sequence, so that the following printed sheets c, d, e are no longer removed. If now in the subsequent rotation of the missing sheet b can be deducted, but not the following sheet c, then engages the controller here and prevents that the following sheets d and e can be deducted. In this starting position, the printing sheets a and b are stacked correctly one after the other in the corresponding receiving pocket. Only in the following rotation can then the remaining sheets c, d, e are sequentially withdrawn in one go, so only now the incomplete loaded receiving bag can be successfully completed.

Method for operating a collection device for printed products, in which the printed products are removed from a delivery device with at least one delivery point and deposited on a collection section one after the other during a cycle period, in which the printed products form at least one package on the collection section within a cycle, which is transferred to a conveying device at a transfer point (1), characterised in that in the operative connection with the conveying device (20) at least two collection sections (21, 30) operate, along each of which a printed package (A-E; HP-VP) consisting of at least one printed product is formed, the individual packages are each conducted to a selected receiving pocket (22) belonging to the conveying device in a subsequent cycle sequence and in the case of a completely formed end product the receiving pocket (22) is loaded with at least one printed product (HP, VP) from the first collection section (30) and at least one printed sheet package (A-E) from the second collection section (21) and in the case of at least one faulty removal of at least one printed product (27, 31) from at least one delivery point (A-E; HP-VP) a repair procedure is triggered in such a way that the missing printed product is removed from the relevant delivery point (A-E, HP, VP) coinciding in time with a following recurring cycle of the conveying device (20) relating to the pockets during a cycle period relating to the relevant transfer point and is put into the relevant receiving pocket (22) incompletely filled with printed products and the number of subsequent repair procedures for providing a complete end product corresponds to at least the number of delivery points (A-E; HP-VP).
2. Method for operating a collection device for printed products, in which the printed products are removed from a delivery device with delivery points and deposited on a collection section one after the other during a cycle period, in which the printed products form at least one package on the collection section within a cycle, which is transferred to a conveying device at a transfer point (1), characterised in that in the operative connection with the conveying device (20) at least two collection sections (21, 30) operate, along each of which a printed package (A-E; HP-VP) consisting of at least one printed product is formed, the individual packages are each conducted to a selected receiving pocket (22) belonging to the conveying device in a subsequent cycle sequence and in the case of a completely formed end product the receiving pocket (22) is loaded with at least one printed product (HP, VP) from the first collection section (30) and with at least one printed sheet package (A-E) from the second collection section (21) and in the case of at least one faulty removal of at least one printed product (27, 31) from at least one delivery point (A-E; HP-VP) a repair procedure is triggered in such a way that the delivery points (A-E; HP-VP) downstream of the at least one printed product not removed supply no further printed products at the same time and the missing printed products are removed from the relevant delivery points (A-E; HP-VP) coinciding in time with a following recurring cycle of the conveying device (20) relating to the pockets in sequence during a cycle period relating to the transfer point and are put into the relevant receiving pocket (22) incompletely filled with printed products.
3. Method according to one of claims 1 or 2, characterised in that the printed product (VP) first taken along the first collection section (30) forms the title page or the back page of the package arising through the following stacked printed product (HP).
4. Method according to claim 1, characterised in that the printed products (HP, VP) lying one on top of the other along the first collection section (30) and/or the printed sheets (A-D) along the second collection section (21) are stacked loosely.
5. Method according to claim 1, characterised in that the printed products (HP, VP) lying one on top of the other along the first collection section (30) and/or the printed sheets (A-D) along the second collection section (21) are stacked in a stable position through surface tension acting on each other.
6. Method according to claim 1, characterised in that at least one printed product (HP, VP) along the first collection section (30) and/or at least one printed sheet (A-D) along the second collection section (21) is provided with surface-effective gluing.
7. Method according to claim 1, characterised in that the conveying device (20) consists of a rotary conveying wheel with n receiving pockets.
8. Method according to one of claims 1 to 7, characterised in that the speed (25) of the conveying device (20) is synchronised with the speed of the collection sections (21, 30) in such a way that in a cycle period at most a single package or in the case of a repair run at most a part package or an individual printed product is put into the receiving pocket (22) of the conveying device (20) allocated at the relevant transfer point (1).
9. Method according to claim 2, characterised in that the number of subsequent repair procedures for providing a complete end product corresponds to at least the number of delivery points (A-E; HP-VP).
10. Method according to one of claims 1 to 6 or 8 to 9, characterised in that the printed products deposited in a receiving pocket (22) are secured against falling out during the translational or rotational movement of the conveying device (20) by means of holding or clamping devices (26).
11. Method according to one of claims 1 to 6 or 8 to 10, characterised in that the translational or rotational speed (25) of the conveying device (20) is designed depending on the number of receiving pockets with respect to the number of delivery points (A-E; HP-VP).
12. Method according to claim 11, characterised in that the cycle period of the conveying device (20) from receiving pocket to receiving pocket (22) is set greater than, the same as or smaller than the cycle period of the collection sections (21, 30).
13. Method according to claim 12, characterised in that the translational or rotational speed of the conveying device (20) is changed during operation.
14. Method according to one of claims 1 or 2, characterised in that the repair path not designed according to the sequence of the printed products is rerouted onto the repair path structured according to the sequence of the printed products and the repair path structured according to the sequence of the printed products is rerouted onto the repair path not designed according to the sequence of the printed products.
