Definitions

  • the present invention relates to a device for performing cutting operations open format edges of at least one printed product, namely for the trimming of at least one head, front, foot edge according to the preamble of claim 1, such as from WO2016 / 168945 A1 evident.
  • open format edges is thus understood to mean head, front and foot parts of the printed product, regardless of whether this is composed of individual pages or signatures.
  • the book blocks or brochures are cut to final size at the top, bottom and front of the unit for a given thickness.
  • the book blocks or brochures are bound on the back. Suitable bindings are all known methods, such as; Thread stitching, perfect binding, saddle stitching, etc.
  • the three-knife trimmer can be used both as a solo machine and as a machine in a line network with other production machines.
  • the task of the device is to cut the printed products, ie mostly book blocks and / or brochures, at the three open sides. This is done by clamping the book block or booklet (hereafter referred to as the book block) at a standstill between press bars or press plates, and using three cutters, the three above-mentioned pages of the book block are trimmed.
  • the cutting devices may be formed as counter-knife units in which two blades cut as a pair of scissors or knife units with cutting strips in which a knife cuts against a solid plastic strip, whereby the knife edge easily penetrates into the plastic strip in the end position for protection.
  • the head and foot incision is usually trimmed in a first phase and the front incision in a second phase.
  • the order is not mandatory, it can also be done the other way round. Furthermore, it is possible to perform on the book block only the head and foot section or only the front section, which is needed for example for the production of English brochures.
  • a three-knife trimmer in which the book blocks to be trimmed are detected by a positioning device and fed to the cutting devices with a feed device.
  • There are a plurality of spaced-apart cutting devices are provided, in which the book block are positioned by the delivery device successively each for a side section. In each cutter, a side cut is made on the positioned print product.
  • the aligned book blocks are moved with an intake gripper by a linear stroke in a transition position, wherein the orientation of the book block is not changed.
  • the delivery of the book blocks is done with a multiple planetary gear.
  • adjustable control gates are provided for positioning of the book blocks in the cutting devices. The device allows easy and quick changeover to other formats.
  • Each cutting device consists of a frame-fixed lower blade and a top blade to which a press plate is coupled via a guide and a pneumatic cylinder.
  • the press plate clamps the book block before cutting between the press plate and the stationary lower knife.
  • the book block is not a large area, but only in the cutting area pressed by the press plate and the lower blade, and the feed device.
  • the areas of the book block that are not pressed tend to be to "sag" and therefore may lead to insufficient cut quality. This is especially the case when the book blocks are made of soft and / or thin paper.
  • a three-knife trimmer is introduced, which can process different book formats in the sequence and in which the outer sides of the book are not damaged.
  • a gripping unit for gripping the back of the printed product is mounted, the gripping unit having a reference surface for positioning the spine of the printed product.
  • the moving member is moved by a controller in a vertical plane and positioned correctly for the cutting operations on the three open sides of the printed product, so that the, moving in the horizontal direction, cutting knife can cut the printed product.
  • the printed product is aligned, thereby enabling the controller, together with the format data, to approach the positions required for the respective cut and to properly position the printed product for the cut.
  • a disadvantage of this latter three-knife trimmer is the limited ability to vary the book format. Due to the fact that one clamping unit holds the printed product for all three sections, the clamping unit has to be designed substantially smaller than the smallest printed product to be processed. If the printed product has a much larger format, then the plates, which are additionally used to support the printed product during cutting, must be provided with a large area of exception. A large exception, however, has a detrimental effect on the quality of cut.
  • the clamping unit can dive more or less deeply into the exception area of the plates.
  • the printed matter is properly supported only when the chuck unit is inserted deeply into the exception area of the plates is.
  • the printed product without replacement of the plates, can be sufficiently supported, only a small difference in bookbord width is editable with the three-knife trimmer.
  • WO2016 / 168945 A1 there is provided means for performing cutting operations on at least one open form edge of at least one printed product, the apparatus being operatively associated with a print product related delivery device for the first cutting operation and a print product related delivery device operating after the last cutting operation.
  • Each edge-related cutting operation is performed with at least one cutting device.
  • the print product is transferable from a first cutting location in which the cutting operation for a first form edge of the printed product takes place to a second cutting location in which the cutting operation for a second form edge takes place.
  • the print product is transferable after the cutting operation has been performed at the second cutting location to a third cutting location in which the cutting operation for a third form edge takes place.
  • the transfer of the printed product from one cutting location to the next is carried out by at least one transport unit, wherein the transport unit has at least one means, which detects the printed product on the back side and conveys it from one cutting location to the next hanging.
  • the present invention is based on the object to provide a trained as a three-knife device;
  • a further object of the present invention is to describe a method for operating such a device designed as a three-knife trimmer.
  • the object of the invention is therefore to be able to with high cutting performance and quality of cut, continuously printing products of the same or different formats and Thickness to process, so by definition cut to format.
  • the inventive three-knife trimmer and its operation are also suitable for trimming stacked brochures according to the same procedure as is the case with a book block.
  • the three-knife trimmer is therefore used for the trimming of open format edges, also called side edges of the printed products, such as books, brochures, magazines used, wherein for the sake of simplicity predominantly the terms “printed product”, selectively “book block” or “booklet” are used below ,
  • the three-knife trimmer By means of the three-knife trimmer according to the invention, reliable processing of very small runs up to the minimum number of pieces 1 can be realized without having to provide stoppages due to a changeover from one to the next format.
  • the three-cutter can be supplied with book block formats of different sizes and / or the production of book blocks can be processed by different sections to be cut off at the edges.
  • the invention is accomplished by an apparatus in which the print product is transferred from a first cutting location in which the first side cutting operation occurs to a second cutting location in which the second side cutting operation takes place, the printing product following the cutting operation performed at the second cutting location is supplied to a third cutting location in which the cutting operation for a third side edge takes place, and that the transfer of the printed product from one cutting location to the next is accomplished by at least one transport unit.
  • the format change takes place in the course of the machine, preferably during the period of time available for the infeed and outfeed of the printed product.
  • the inventive three-knife trimmer can be used even with a run of a printed copy, the goal of the trimmer according to the invention must be seen in the fact that the copy only once available is cut 100% reliable.
  • Another significant advantage of the invention is the fact that the three-knife trimmer is simple in design and reliable, so that its operation can be done even by auxiliary personnel.
  • the inventive three-cutter is ensured that the dimensional accuracy of the cut printed product and its straight, parallel and rectangular cuts are guaranteed against the front and back surface of each printed product.
  • the inventive three-knife trimmer thus ensures a high quality of cut even with larger print product thicknesses by the printed product is maximized over the entire surface by at least one pressing device between the first and last page clamped, during which the cutting operations at the upcoming open side edges, so that in this cutting operation the risk of quality-reducing "nose" in the cut book block can be excluded.
  • the full-surface detection of the printed product can be achieved if required by a plurality of press plates or recordable by segmented press plates or individually operable pressing elements.
  • the printed products are lying, with the binding processed back ahead and fed with approximately the same pitch via a conveyor belt to the three-knife trimmer.
  • the approximately uniform pitch is given either by a clocked supply of the printed products to the conveyor belt of the three-knife trimmer, or such feeding is produced by known devices and methods in front of the conveyor belt.
  • the printed products with an irregular pitch are fed to the conveyor belt of the three-knife trimmer.
  • a timing device ensures that minimum pitches (distance between the leading book spine edge and the spine edge of the subsequent product are not undershot.)
  • a sensor detects when the printed product arrives at the conveyor belt of the three-knife trimmer.
  • the spacing between the printed products is greater than the minimum spacing, it may be provided as the first preferred variant that the printed products located within the three-cutter process are finished, and then the infeed is resumed.
  • the control reduces the speed of the three-knife trimmer and synchronizes the three-knife trimmer to the cycle of the printed product. If the division then exceeds a maximum dimension, then it can also be optionally provided that the controller generates empty cycles on the three-knife trimmer.
  • the head part is cut at the first cutting location, the front part at the second cutting location, and the foot portion of the printed product at the third cutting location.
  • a further transport unit of the printed products from one cutting location to the next is that at least two, three supports run along a substantially circular, round, elliptical-like path, said functional circumferential path consisting of a front and a substantially parallel rear path, wherein the two paths merge into each other through a lateral curvature.
  • the front track serves to guide the supports straight or quasi-straight along the cutting edge.
  • the number of supports along the route is dependent on the maximum allowable clock, that is, each support takes a leading role in a printed product, and performs this without transfer in the sense of the above statements on the three cutting locations.
  • the clock is designed so that the supports closely follow each other, and the distance to each other depends on the time taken for the individual cutting operations, which usually more than two or three supports are in use. For example, a reduction in the number of supports can be achieved as they accelerate along the trailing path between the last and first cutting operations.
  • the intermediary cutting site specific levies and takeovers of the printed product can be circumvented by reciprocating supports.
  • more peripheral support usually needs to be provided, and at the same time the infrastructure of the elliptical track is more demanding.
  • Such a transport variant characterized by an ellipse-like route is well-suited for a central trimming of the printed products set, so if the three cutting operations are carried out at a single cutting location, so if the acquisition of the printed product, its delivery to the central cutting location, and its subsequent delivery by one and the same support.
  • this support does not drive back on the front track, which would inhibit the production flow, but undertakes the return trip for the acquisition of a new printed product then on the rear track.
  • the press beam is preferably located at the lower end of a spindle which is drivingly connected to a servomotor controlled by a servo drive, via a line.
  • the servo drive is connected via another signal line with a sensor that detects the position of the press beam.
  • the spindle moves the press bar in the direction of the printed product.
  • the servo drive is also connected to a higher-level control.
  • the printed product is then trimmed at the front and then with two side knives on the head and on the foot using a cutting tool known as a knife.
  • the order of cuts can also be reversed, head and foot before front trim. It is obvious that the movement of the side knives and the associated press beams must be made out of phase with the movement of the front knife and the associated press beam, so that a collision of the knife can be prevented. So as soon as the cutting is done by the side knives, the local pressures (clamping device, pressing bars) are terminated and the cut printed product is carried away.
  • this procedure is not necessarily specified, in particular as regards the machining sequence of the first and third cutting locations, according to which the first trimming always has to be the head part, but it is readily possible to have the foot section at the first cutting location and then edit the head section at the third cutting location, wherein at the second cutting location as before, the circumcision of the front part of the printed product is carried out, this optimally designed to follow the present invention based on translational movements follow.
  • Whether the head or foot section is machined at the first cutting location depends on how the feed of the printed product to the three-knife trimmer is scheduled, i.e., whether the reading front side of the printed product is directed up or down on the conveyor belt. In both cases, the back edge of the printed product remains in transit to the three-cutter prior. If such a change (head / foot section) is made, then it must be ensured that appropriate control-technical precautions are taken for the sections to be cut off, in particular when head and foot sections with different section lengths are to be processed.
  • the gripper itself is end equipped with pressure-product-related jaws, said gripper resp. the one or more supports at the cutting locations has an additional translational degree of freedom in all the above-mentioned planes (X, Y, Z).
  • the seizure of the respective printed product is maximized at its center of gravity, and / or the seizure of the printed product in dependence on the cut off sections on the open side edges (head, front, foot) coincides with the best possible geometric location, with the latter possibility a medium to strong Deviation from the theoretical focus of the printed product is possible.
  • the cutting stations of the three-knife trimmer are at each cutting place in operative connection with at least one stationary, quasi-stationary or movable force-acting clamping device, which is responsible for the basic detection and generation of the pressing force on the printed product to be trimmed, this clamping device is tuned to the format size of the printed product , So has an optimized fixed contact surface, or in the course of Operation can be adjusted by simultaneous adjustments to the respective format sizes of the printed product.
  • the closing force of the jaws of the gripper does not affect the pressing force of the clamping device and its vectors on the printed product. This means that the pressing force of the clamping device relative to the closing force of the jaws of the gripper behaves absolutely effective and Kräftgiandominant.
  • At least one clamping device within the three-knife trimmer can consist of two clamping jaws, which execute at least one force-exerting closing movement relative to one another. Furthermore, at least one further clamping device can be made of individual composite pressing bars at a suitable cutting location, which exert the pressing force on the pressing surfaces of the printed product, these pressure bars in their entirety forming a pressure bar battery.

  • This precipitation device 500 which is not shown in more detail, is designed so that on the one hand the integrity printed products are "let through” while the printed products recognized as deficient are rejected, whereby an alternative is also incorporated, so that further distinction is made between a final 520 and a final one conditional elimination 530. In the latter case, the requirements should be met that these printed products can be converted into perfect print products by post-treatment.

As long as "good” print products 510 are being promoted, the roles remain inactive.

  • the book block is almost completely pressed by staples or pressure bar batteries. Only in one area of the spine does the book block have an open space M 1 . This is not critical because the bound book block in this area is sufficiently compact, and in the cutting area the pressure bars within the respective cutting station of the cutting devices support the book block. The full-surface pressing of the book block leads to a high quality of cut.
  • the full-surface pressing is achieved in a simple manner: There are no webs, support elements or support strips format dependent to be adjusted. As a result, a high number of cycles and thus a high performance of the three-knife trimmer can be achieved.
  • the three cutting stations 141, 142, 143 of the cutting device are arranged U-shaped with the open side of the U down against each other.
  • the section of book block to be cut is operative in all three cutting operations in association with the pressing bars 144 (see FIG FIG. 7 , and particularly FIG. 10 ) against the inside of the U-shape.
  • the book block height varies, depending on the envelope, the book is more or less in front of the book.
  • the book blocks are made with a solid overhang of the envelope on one side and a variable overhang on the other side.
  • the uncut book block or the uncut booklets are aligned at the foot or head edge and the processed back edge.
  • the variable projections of the envelope in the book block height and the book width play no role.
  • the three-cutter control product data For each book block to be cut or for each booklet to be cut, the three-cutter control product data must be known, from which the necessary movements of the transport organs can be expected, so that at the end a cut book is produced, which has the desired format dimensions.
  • Each book block or booklet is equipped with an identification feature.
  • a feature reader at the entrance of the three-knife trimmer reads the identification feature (eg: one or two-dimensional barcode, RFID chip, character, image, etc.) and transmits the information from the feature with the machine cycle allocation to the controller.
  • the feature may include the necessary information mapping the cut print product dimensions, or the missing information may be supplemented from a database.
  • the book blocks are clocked fed to the three-knife trimmer.
  • the three-cutter control is supplied with the information necessary to cut the book block to the correct dimension.
  • data supplied with the book block can be supplemented with data from a database.
  • Another possibility is to make the data known to the three-knife trimmer with an order of the book blocks before the book blocks are fed.
  • the three-knife trimmer processes the next record in the given order with each book block being fed.
  • the feeding of the book blocks must be done in the right order.
