Abstract

A postpress system ( 1 ) and method for producing and processing product units (P), in particular printed end products (P) with printed product collections comprising a plurality of products, selected from the group of wrapping products, and a plurality of part products and/or inserts, to make route adapted stacks or packs, at least some of the printed end products (P) being product units which have been customized for specific addressees are proposed. By using feed devices ( 3 ) which each comprise a supply conveyor ( 31 ), a preparation circuit ( 32 ) with a plurality of transport units ( 321 ) and an output conveyor ( 33 ), printed products (D) are fed in a controlled fashion to the holding units ( 21 ) with reliability. A sorting device ( 6 ) with at least one directing group with at least one gate ( 62 ), a transit section ( 612 ) and at least one supply section is used to correct faults, or deviations in the product sequence from the production sequence.

First claim

I claim:

1. A method for operating a postpress system ( 1 ) for producing and processing printed end products (P) with printed product collections including a plurality of products selected from the group of wrapping products, and a plurality of part products and/or inserts, to make route adapted stacks or packs, wherein at least some of the printed end products (P) are individualized product units for specific addressees, comprising the following steps:
i) collecting printed product collections out of a plurality of printed products (D) in holding units ( 21 ) along a collecting section ( 2 ), wherein printed products (D) are fed to the holding units ( 21 ) by feed devices ( 3 ), each of the feed devices ( 3 ) including a supply conveyor ( 31 ), a preparation circuit ( 32 ) with a plurality of transport units ( 321 ) and an output conveyor ( 33 ), wherein the transport units ( 321 ) are arranged on the preparation circuit ( 32 ) independently of one another and can be conveyed at a variable distance from one another and the transport units ( 321 ) comprise carriages, with grippers ( 322 ), which can move freely in a track and wherein, in each case, one printed product (D) is transferred at an output point of the supply conveyor ( 31 ) to a transport unit ( 321 ) of a preparation circuit ( 32 ), transported by the transport unit to the output conveyor ( 33 ) and output to it, and subsequently the output conveyor ( 33 ) outputs the products (D) to the provided holding units ( 21 ) of the collecting section ( 2 , 2 ″), wherein the feed device outputs the printed products to the collecting section in a controlled fashion;
ii) transferring the printed end products (P) to a sorting device ( 6 ) according to a product sequence (S ist );
iii) comparing an actual sequence of the individual printed end products of the product sequence (S ist ) with a planned sequence of printed end products according to a production sequence (S soll );
iv) one of:
a) transporting the printed end products (P), without any change in the sequence, through the sorting device with the product sequence (S ist ) matched to the production sequence (S soll ), and
b) temporarily storing a repair group (R) comprising a plurality of printed end products (P), with a sequence which deviates from the production sequence (S soll ), in a supply section ( 611 ) of a directing group and subsequently conveying together, in the correct sequence, the corrected and/or newly produced printed end products with the printed end products of the repair group; and
v) transferring the printed end products (P) in an actual product sequence (S ist ,) to at least one stacking device ( 5 . 1 , 5 . 2 ) for producing stacks or packs.

2. The method for operating a postpress system ( 1 ) according to claim 1 , wherein the preparation circuit ( 32 ) outputs the printed products to the output conveyor ( 33 ) in a controlled fashion.

3. The method for operating a postpress system ( 1 ) according to claim 1 , wherein the output conveyor ( 33 ) outputs the products (D) in a controlled fashion to the provided holding units ( 21 ) of the collecting section ( 2 ).

4. The method for operating a postpress system ( 1 ) according to claim 1 , wherein a checking unit checks that the transport units ( 321 ) of the preparation circuit ( 32 ) only leave the output point when they have picked up a product (D).

5. The postpress system ( 1 ) according to claim 1 , wherein the grippers ( 322 ) function to grip and releasably retain he products (D).

6. The method for operating a postpress system ( 1 ) according to claim 1 , wherein the sorting device comprises at least one directing group with at least one gate, a transit section and at least one supply section.

7. A postpress system ( 1 ) for producing and processing printed end products (P) with printed product collections including a plurality of products (D), selected from the group of wrapping products, and a plurality of part products and/or inserts, in at least one stacking device ( 5 . 1 , 5 . 2 ) to make route adapted stacks or packs, at least some of the printed end products (P) being product units which have been customized for specific addressees, comprising:
a collecting section ( 2 , 2 ″), with a plurality of feed devices ( 3 ), each of the feed devices comprising a supply conveyor ( 31 ), a preparation circuit ( 32 ) with a plurality of transport units ( 321 ) and an output conveyor ( 33 ), and a collecting circuit with a plurality of holding devices ( 21 ), wherein the transport units ( 321 ) are arranged on the preparation circuit ( 32 ) independently of one another and can be conveyed at a variable distance from one another and the transport units ( 321 ) comprise carriages, with grippers ( 322 ), which can move freely in a track and wherein the feed devices are designed such that they output the products (D) to the plurality of holding devices ( 21 ) of the collecting section ( 2 , 2 ″) in a controlled fashion via the preparation circuit ( 32 ) and
a sorting device ( 6 ), the sorting device to allow transport of the printed end products (P) which are in correct sequence directly through the sorting device and to temporarily store printed end products belonging to a repair group (R) in a supply path ( 611 ) of a direction group until the group is repaired and at the same time correct groups may be passed through the sorting device.

8. The postpress system ( 1 ) according to claim 7 , wherein the preparation circuit ( 32 ) is designed for the controlled output of the printed products (D) at the output conveyor ( 33 ) and/or the output conveyor ( 33 ) is designed for the controlled output of the printed products (D) to the provided holding units ( 21 ) of the collecting section ( 2 , 2 ″).

9. The postpress system ( 1 ) according to claim 7 , wherein a checking unit is provided which checks that the transport units ( 321 ) of the preparation circuit ( 32 ) only leave the output point when they have picked up a product (D).

10. The postpress system ( 1 ) according to claim 7 , wherein the grippers ( 322 ) function to grip and releasably retain the products (D).

11. The postpress system ( 1 ) according to claim 7 , wherein the sorting device comprises at least one directing group with at least one gate, a transit section and at least one supply section.

12. A method for operating a postpress system ( 1 ′) for producing and processing product units with printed product collections including a plurality of printed products (D), selected from the group of wrapping products, and a plurality of part products and/or inserts, to make route adapted stacks or packs (S), at least some of the product units being customized for specific addressees, comprising the following steps:
i) collecting product collections from a plurality of printed products (D) in holding units ( 21 ) of a collecting section ( 2 ′, 2 ″), printed products (D) being fed to the holding units by feed devices ( 3 );
ii) completing the product units (P) comprising the product collections;
iii) transferring the product units (P) to a sorting device ( 6 ) according to a product sequence (S ist );
iv) comparing an actual sequence of the individual product units of the product sequence (S ist ) with a planned sequence of product units according to a production sequence (S soll );
v) one of:
a) transporting the product units (P), without any change in the sequence, through the sorting device with the product sequence (S ist ) matched to the production sequence (S soll ), wherein the product units are transported in the sorting device by transport units which are arranged independently of one another and can be conveyed at a variable distance
