Abstract

A device for carrying out cutting operations on an unbound formatting edge of a printed product includes a cutter to carry out edge-related cutting operations. A transporter transports the printed product from a first cutting location, at which the first cutting operation for a first formatting edge of the printed product takes place, to a second cutting location, at which a second one of the cutting operations for a second formatting edge takes place, and to a third cutting location, at which a third one of the cutting operations for a third formatting edge is carried out. The transport of the printed product from one cutting location to the next is carried out along a guide section. The transporter includes a gripper with which the printed product is gripped by the spine and conveyable from one cutting location to the next in a suspended manner.

First claim

What is claimed is:

1. A device for carrying out cutting operations on at least one unbound formatting edge of at least one printed product, the device comprising:
at least one cutter configured to carry out each of a plurality of edge-related cutting operations; and
at least one transporter operatively connected to a printed product-related advancing device for a first one of the cutting operations and to a printed product-related transporting device, which is operative after a last one of the cutting operations, whereby the printed product is transportable from a first cutting location, at which the first cutting operation for a first formatting edge of the printed product takes place, to a second cutting location, at which a second one of the cutting operations for a second formatting edge takes place, and to a third cutting location, at which a third one of the cutting operations for a third formatting edge is carried out, after the second cutting operation at the second cutting location has been carried out,
wherein the at least one transporter includes a guide section such that the transport of the printed product from one cutting location to the next is carried out along the guide section, and
wherein the at least one transporter includes a gripper with which the printed product is gripped by the spine and conveyable from one cutting location to the next in a suspended manner.

2. The device according to claim 1 , wherein the printed product to be cut comprises a connected book block, individual brochures or a number of stacked brochures.

3. The device according to claim 1 , wherein the printed products, before and/or after the cutting operations, have the same or variable format dimensions with the same or different thickness dimensions.

4. The device according to claim 1 , wherein:
the first edge to be cut at the first cutting location relates to a head portion, the second edge to be cut at the second cutting location relates to a front portion, and the third edge to be cut at the third cutting location relates to a tail portion of the printed product, or
wherein the first edge to be cut at the first cutting location relates to the tail portion, the second edge to be cut at the second cutting location relates to the front portion, and the third edge to be cut at the third cutting location relates to the head portion of the printed product.

5. The device according to claim 1 , wherein the advancing device for alignment in terms of location of a printed product configured as a book block has the shape of a multi-part insertion wheel, which is operable according to the following criteria:
a) during a first 90° rotation of the insertion wheel, a rake-like guide, which is folded with respect to the book block, carries out a pivotable movement in such a way that the book block lies on its spine after the 90° rotation, whereupon the book block is secured against fanning out and/or falling over;
b) the rake-like guide is coupled to a clamping assembly, by which the book block lying on its spine is momentarily clamped, wherein the clamping assembly is kinematically operable in such a way that the rake-like guide is transportable into a book block thickness-dependent position;
c) thereafter, the clamping assembly opens again so that the spine of the book block, following gravity, is aligned with a stop face within the insertion wheel;
d) thereafter, the clamping assembly closes again, whereupon the book block has a defined position;
e) the insertion wheel then rotates by two clock cycles through 90° in each case per clock cycle, whereby the book block is transportable into a position, which is now suspended, with respect to the cutting locations;
f) during the rotary movement in e), the first rake-like guide and a second guide, which is operatively connected thereto, are pivoted away from the book block, the book block being held in a region at least of one part of its spine by the clamping assembly, wherein the portion of the book block released by the guides is suspended vertically downward solely due to gravity.

6. The device according to claim 5 , wherein, in an open state of the clamping assembly, additional means are present, which are drivable from above and/or from the side, by which a brief pressing force is exertable directly or indirectly on the book blocks, and by the pressing force, a securing of the end position of the book blocks is achieved with respect to the stop face or another predetermined position at least in the horizontal direction.

7. The device according to claim 1 , wherein the advancing device for a printed product comprising at least one brochure, has the shape of a multi-part insertion wheel, which is operable according to the following criteria:
a) during a first 90° rotation of the insertion wheel, a rake-like guide, which is foldable with respect to the brochure, carries out a pivotable movement in such a way that the brochure lies on its spine after the 90° rotation, whereupon the brochure is secured against fanning out and/or falling over;
b) the rake-like guide is coupled to a clamping assembly, by which the brochure is momentarily clamped in a position lying on its spine, whereupon this clamping assembly is kinematically operable in such a way that the rake-like guide is transportable into a book block thickness-dependent position;
c) thereafter, the clamping assembly opens again so that the spine of the brochure, following gravity, is aligned with a stop face within the insertion wheel;
d) thereafter, the clamping assembly closes again, whereupon the brochure has a defined position;
e) the insertion wheel thereupon continues to rotate by two clock cycles through 90° in each case per clock cycle, whereby the brochure is transportable into a position, which is now suspended, with respect to the cutting locations;
f) during the rotary movement in e), the first rake-like guide and a second guide, which is operatively connected thereto, is pivotable away from the brochure, wherein the brochure is held in a region of at least one part of its spine by the clamping assembly, wherein the portion of the brochure released by the guides is suspended vertically downward solely due to gravity.

8. The device according to claim 1 , wherein the advancing device is operatively connected in a region of the first cutting location to a movable clamping device, which is equipped with clamping plates and accepts the printed product from the advancing device, whereupon the printed product is fed to the first cutting operation.

9. The device according to claim 1 , wherein the transporter comprises at least of a support having at least one printed product-related gripper, wherein the gripper is configured to grip the printed product to be cut on a spine side of the printed product, and wherein the following controller-assisted translatory movements along a guide section are taken as a basis for the gripper with respect to the cutting locations:
a) accepting the printed product by use of the gripper belonging to the support after completion of the first cutting operation at the first cutting location;
b) transporting the printed product by the same support/gripper to the second cutting location and, after the cutting operation has taken place at the second cutting location,
c) transporting the same printed product by the same support/gripper to the third cutting location to carry out the third cutting operation, and thereafter,
d) initiating return of the same support/gripper into the starting position at the first cutting location for a renewed acceptance of a subsequent printed product, once the first cutting operation has been carried out thereon at the first cutting location.
