Method for operating at least one first processing machine for

Material sections of flat material

The invention relates to a method for operating at least a first

Processing machine for material sections of flat material.

Printing machines, for example sheet-fed printing machines, for printing on

Material sections of substrate or printing material, in particular flat material, for example sheets and / or plates, are usually supplied with substrate or printing material in such a way that a stack of substrate or printing material is arranged on a pallet in the region of an investor of the printing machine and these material sections are separated and at least one Printing unit to be supplied. After printing on these material sections, they are collected in the area of a display,

especially again in the form of a stack.

Regardless of the assignment of the print motifs to the front and back of a finished printed product, a first,

Coating carried out on a first side of the substrate or substrate transferring printing operation and a second, coating agent on a second, the first side opposite side of the substrate or substrate transferring printing operation. Under a printing process is a processing by the

Understand printing machine in which at least one printing unit or coating plant coating agent, in particular ink, ink or paint on the substrate or the substrate applies. The passage through several printing units and / or coating units is to be understood here as a whole as a single printing process when the

Material portions of the substrate or substrate between them are not collected on a stack. When turning over a material section of the flat material, in particular an arc of the substrate or printing substrate, essentially a rotation of 180 ° is made. Different axes of rotation are possible. If, in such a procedure, an edge oriented in the first printing operation as the leading edge of a material section is also used as the leading edge in the second printing operation, this is called a turn-over, otherwise an everting. The same applies to a simultaneous turning of several sections of material, for example when turning over a stack as a whole. The same applies to other types of processing of the substrate, such as those in which material sections of flat material are painted and / or dried and / or folded and / or glued and / or embossed.

Processing machines usually require at least one set-up process for at least one or more or each processing operation, in which the

Processing machine is set up. At least in the case of a printing machine, for example, register and / or register and / or tempering and / or quantities of inking solution to be transferred and / or quantities to be applied must be set up in order to achieve an optimum printing result. As a rule, waste paper is produced, that is to say a certain amount of substrate, in particular a sheet, which has not been processed completely and / or at least in insufficient quality. In a two-sided processing usually a first setup process for the processing of the front side of the substrate and a second setup process for the processing of the back of the substrate is necessary. In an ideal case, the waste obtained in the first setup process and processed only on a first page can be used again for the second setup process, in which case preferably its back is processed, in particular again not complete and / or at least in insufficient quality. In this way, less waste is generated overall.

Methods are known in which sheets are first printed on one side and are then collected on a stack and in which this pile is turned as a whole and the sheets of this turned pile are separated again and printed.

DE 10 2008 029 998 A1 discloses a method in which decolorizing sheets are marked and can therefore be discharged during further processing.

From DE 10 2006 050 774 A1, a method is known in which a sheet coming into contact with a support element for a stack change is marked, before it is processed by a processing machine, wherein detection of the marking is used to inform an operator with respect to one to inform to be performed stack change. In DE 100 42 157 A1, the detection of a marked sheet is used to selectively remove a sheet.

From DE 103 15 449 A1 a method is known in which transported sheets are counted until a marking element is detected and the determined number is further used.

The invention has for its object to provide a method for operating at least a first processing machine for material sections of flat material.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular that it can be avoided that in a first processing operation, in particular for the processing of their front side, successfully processed material sections in a second

Machining process, in particular for processing their back, instead of a successful processing fail as waste, because they are used for particular second means of the processing machine. Furthermore, an operation the at least facilitates a first processing machine. In particular, in this way, a processing machine can be operated with less manpower and / or less time spent, as if an operator would monitor a device of the second processing operation and at the same time this or another

Operator should observe a corresponding stack to prevent material sections are unintentionally used to set up the machine. Thus, the Einrichtemakulatur the first processing operation can be on the same stack, as the successfully processed in the first machining process material sections, wherein a first mark makes the transition indicates or at least is in a known relationship to the transition. As a result, the Einrichtemakulatur the first processing operation safely to the

Setup be used for the second processing operation, because there is no risk that unnoticed unnoticed already successfully processed material sections drawn by ongoing application of material sections and by the second

Einrichtevorgang be made unusable.

Preferred is a method for operating at least a first

Processing machine for material sections of flat material, in particular substrate. In this case, a first amount of the material sections after at least a first

Processing stage and / or collected after at least a first processing operation in the form of at least a first stack. The first processing level is

For example, a processing stage of the first processing machine or a processing stage of a second processing machine. The method is suitable both for processing the front side of the material sections and subsequent processing of the rear side of the material sections by means of the same

Processing machine, as well as for a first processing by means of a

Processing machine (which would then be called second processing machine, for example) and a subsequent processing by means of another

Processing machine (which then, for example, first processing machine to call would). In this case, irrespective of the number of processing machines, the first quantity of material sections between two processing operations is collected at least once on a stack, for example delivery stack. The first quantity of the material sections is preferably collected in a delivery of the first processing machine or corresponding to the second processing machine in the form of at least one first stack.

Preferably, at least one first mark is introduced into the first stack.

Preferably, the at least one first mark is introduced during formation of the first stack of individual material sections in the first stack, ie in particular before completion of forming the first stack and more preferably before material sections of a second subset introduced into the stack and in particular placed on the stack , Preferably, the at least one first mark is introduced manually or automatically into the first stack. By introducing the first marking into the stack, in particular, also depositing one

Material section on or in the stack meant, which substantially corresponds to the remaining material sections, but at least one distinguishing feature, for example, another printed image or no printed image or other

Labelling. This distinguishing feature has been added to this material section, for example, within the processing machine. Preferably, the at least one first marking serves to identify a transition from a first subset of the first set of material sections to a second subset of the first set of material sections.

Preferably, a plurality of, more preferably more than half and even more preferably all material sections of the first subset differ from a plurality, preferably more than half and more preferably all material sections of the second subset, for example by a respective print motif and / or a quality of a respective print image and / or a membership of a respective one Print job. For example, the method is characterized in that preferably at least 50%, more preferably at least 75% and even more preferably all of the material portions of the first subset of preferably at least 50%, more preferably at least 75%, and even more preferably all of

The procedure can be used to separate set-up waste and good sheets. Then, the first subset preferably predominantly waste and has the second subset preferably predominantly good bow. However, it is also possible to mark a transition between the print jobs in successive print jobs in this way. For example, a first or a last cleaning material section or clean printing sheet is marked. A clean sheet is

Typically, a portion of material used in an offset printing press to remove ink from a transfer cylinder without feeding new ink from an inking unit onto the transfer cylinder. After a certain number of sections of material, the transfer cylinder is cleaned and ready for use in a new print job. By marking the clean print sheets, which also come to rest on a delivery pile, a transition between print jobs is marked in the delivery pile. As long as it is known by how many material sections the marking and the actual respective

Transition distinguished, it is also possible to install the mark spaced from the actual transition. A distance is here as a number of

Understand material sections. In particular, with the method, a plurality of markers per stack can be inserted and detected, for example, to separate more than two subsets of material sections within a stack.

Preferably, the first stack of the first processing machine is supplied. If appropriate, in particular if the first processing operation has already taken place by the first processing machine, the first stack is in particular supplied again to the first processing machine.

Alternatively or additionally, the method is preferably characterized in that the at least one first marking is introduced into the stack by arranging at least one transmitter and / or receiver for electromagnetic signals in the stack and / or on one of the material sections. Such a transmitter and / or receiver is, for example, at least one RFI D transmitter and / or RFI D receiver. RFID stands as an abbreviation for "radio-frequency identification".

Irrespective of the way in which the at least one first marking is introduced into the first stack, the at least one first marking has, for example, at least one barcode and / or matrix code.

Such a first marking can be applied automatically, for example, regardless of its characteristics. Alternatively, the at least one first mark is manually attached. For attaching the at least one first is preferred

As a result, subsequent material sections can be stopped at least for a short time, in particular in order to obtain access to an uppermost material section already stored on the first stack. By way of example, the at least one first marking is arranged by marking an uppermost section of material lying on the first stack with a pencil by an operator. After attaching the at least one first mark is preferred at least one Retaining means again removed from the transport path of the material sections and more preferably a previously held by the at least one holding means partial stack stored on the at least one first mark bearing material sheet of the first stack.

Alternatively or additionally, the method is preferably characterized in that a calculation takes place in response to the detection of the at least one first marking, when a last material section of the first subset and / or a first material section of the second subset reaches a predetermined position within the first processing machine , Then, an exact separation between waste of the first set-up and successfully processed material sections of the first processing operation can be made and accidental further processing or destruction of a corresponding section of material can be avoided.

Alternatively or additionally, the method is preferably characterized in that, in response to the detection of the at least one first marking, at least one

Holding means is introduced into a transport path of the material sections. For example, at least one or preferably a plurality of sample sheet fingers are introduced into the transport path of the material sections. Preferably, the at least one holding means and more preferably the at least one sample sheet finger is introduced into a region of the transport path, which is arranged directly in front of the stack to be formed. As a result, subsequent material sections can be stopped for at least a short time. More preferably, therefore, the first subset of material sections, which has served to set up the processing machine, separated from a second subset of the material sections, which consist of successfully processed on both sides of material sections. The first subset is then preferably transported away and the second subset is collected separately on a corresponding stack and preferably further processed.

An embodiment of the invention will be described in more detail below.

A processing machine is preferably designed as a processing machine for processing material sections of flat material, for example a curved substrate, in particular a sheet-shaped printing material. Preferably, the Processing machine at least as a printing machine, in particular as a sheet-fed printing machine.

In the following, the preferred case of a printing press, in particular sheet-fed printing machine is described, but the method is also applicable to others

Processing machines, in particular sheet-processing machines transferable, for example, those in which material sections of flat material painted and / or dried and / or folded and / or glued and / or embossed. A printing machine should be understood to mean a device by means of which at least one coating agent can be applied to at least one substrate, in particular printing material. Substrates or substrates used are, for example, web-form substrates or substrates or preferably material sections of flat material. The flat material therefore preferably consists of arcuate and / or plate-shaped goods. Material sections of formed as a flat substrate or

Substrate are, for example, sheets or plates, preferably with a regular, in particular rectangular outer peripheral contour. Sheet and plate are characterized in particular by the fact that their smallest dimension, insbesondre whose thickness, at most a fraction, for example at most one tenth, in particular at most one twentieth corresponds to each orthogonal dimension, for example, a length and / or width. For example, they have a thickness, ie the shortest dimension of at most 20 mm, in particular between 0.03 mm to 10 mm. Sheets and plates consist for example of metal and / or plastic and / or wood and / or cardboard and / or cardboard and / or paper and / or stone and / or glass. A plate has, for example, a shortest dimension, for example a thickness, of more than 0.5 mm, for example between 0.5 and 20 mm, in particular between 0.5 and 10 mm. An arc has, for example, a shortest dimension, for example a thickness of at most 0.8 mm, in particular between 0.03 and 0.5 mm. If, in the following, arc is mentioned, it should nevertheless generally be understood as meaning material sections of a flat material, in particular also plates. The coating agent used is preferably at least one printing ink and / or at least one ink and / or at least one paint. For example, the at least one printing press has at least one printing unit, in particular at least one offset printing unit and / or at least one inkjet printing unit and / or at least one flat printing unit and / or at least one gravure printing unit and / or at least one

High-pressure plant and / or at least one printing unit and / or at least one

Screen printing and / or at least one coating on. At least in the case of one

Offset printing unit or optionally a printing unit for another form-based printing method, the at least one printing unit preferably has at least one printing plate, for example at least one printing plate and / or at least one printing sleeve.

The processing machine preferably has at least one feeder. By means of the investor, the material portions of the preferably formed as a substrate or substrate sheet, preferably in the form of a stack, in particular

Plant stack delivered, isolated and further processing stages of the

Processing machine fed in succession. Preferably, such stacks are each arranged on transport aids, for example on pallets. A transport unit preferably has at least one stack of material sections of the flat material and more preferably also at least one transport aid. Optionally, at least one mark is also part of the transport unit. Stacks and transport aids thus further preferably together form a transport unit, optionally together with at least one marking. The separated material sections are then processed within the processing machine, coated, for example, within the printing press, in particular printed and / or painted and / or dried and / or folded and / or glued and / or embossed.

In the following, printing is described as processing, but in any case, the embodiments are also to be transferred to general processing, as far as they are concerned make no contradictions. After completion of the processing of the material sections by the processing machine, the material portions of the flat material, in particular sheet, in a display area, for example by means of a boom, in particular sheet delivery, collected, in particular combined to form a new stack. A display area, in particular a display area of the processing machine, therefore preferably has at least one sheet delivery and / or a device for uninterrupted stacking even during a removal of a stack. In particular, a stack is a stack of a plurality of sheet-shaped or plate-shaped goods, regardless of whether it is a respective investment stack or a delivery stack or another stack.

The investor is preferably a known investor, in particular sheet feeder. The feeder or the processing machine preferably has at least one mark sensor, in particular in the region of the feeder. Such a mark sensor preferably serves to detect at least one preferably unique first marking, in particular a first marking of a corresponding stack. The plant stack is preferably raised stepwise or continuously during operation of the processing machine in the region of the feeder, in order to arrange a respective upper material section of the plant stack at a position which can be reached by the feeder. After an end of a processing operation, for example, a remaining investment pile or an empty transport aid will remain in the feeder. This remaining investment pile or this empty transport aid is then preferably lowered again in order to remove it or it from the area of the sheet feeder can.

For example, the investor is trained as an investor designed for uninterrupted working. Then, the feeder, for example, a lifting device with a vertically movable by a drive lifting floor through which a pile in abutting position during a taking place from above by appropriate conveyors material removal is nachförderbar up, so the removal height of the top of the material sections is always maintained. Furthermore, in this case, the feeder comprises a second lifting device with a rake that can be moved vertically by a drive, which can be moved horizontally between the hob bottom and the lower end of the stack carried by the hob floor at a first working height. By means of this second lifting device, the remaining stack picked up by the lifting bottom can be conveyed upwards during the removal of material from above by corresponding conveying devices, so that the removal height of the uppermost of the material sections is maintained. The lifting floor of the first lifting device can then be moved back into its lower receiving position, so that it can take a next batch, while the supply of material through the residual stack is further ensured. After a new stack has been brought into the abutment position on the lifting floor, this can be moved vertically until the upper end of the new stack has reached the lower end of the rest of the stack. Finally, the rake can be removed from the stack, for example, by moving it horizontally.

The boom is preferably a known boom, in particular sheet delivery. Before starting a machining operation, an empty transport aid is preferably positioned in the delivery arm in order to receive the processed material sections of the flat material in the form of a stack, in particular a delivery stack. The delivery stack is preferably lowered gradually or continuously during operation of the processing machine in the region of the delivery arm in order to be able to arrange a material section to be placed on top of it at a position which can be reached for the delivery device. After an end of a processing operation, for example, a resulting delivery stack will have arisen in the delivery. This resulting delivery stack is then preferably lowered to a removal position in order to remove it from the area of the sheet delivery.

For example, the boom is designed as one for uninterrupted working Boom trained. Then, the boom, for example, a lifting device with a vertically movable by a drive lifting floor, through which a stackable in the delivery position through the processed material sections stack during conveyance taking place from above by a corresponding conveyor material is conveyed downwards, so that the storage height of the top the material sections is always preserved. Preferably, the boom has a second lifting device with a vertically movable by a drive support means, such as a board or preferably a roller blind, which is horizontally movable in a first working height between at least an upper part of the already formed stack and the lifting floor. By means of this second lifting device, a new stack to be formed is carried in its working state by receiving the following sections of material, while the previously formed stack can be removed underneath. Thus, during the removal of the one stack, the recording of the processed material sections in a new stack further ensured After the previous stack was removed from the delivery position, the lifting bottom of the first lifting device can be moved vertically again until it has reached the lower end of the new stack and this supports.

Finally, the support device can be removed from the stack, for example, by moving it horizontally.

Preferably, in particular in addition to the at least one lifting floor, at least one holding means is arranged, by means of which at least temporarily an incoming stream of material sections can be kept. In this way, a period is created during continuous operation of the processing machine, in which one is provided as a top sheet on the delivery stack with a mark and / or by otherwise at least a first mark is introduced into the delivery stack. The delivery pile is also called the first pile. During setup of the processing machine and / or operation of the processing machine, a first quantity of

Material sections collected after at least a first processing stage in the delivery of the processing machine in the form of this first stack or delivery stack. Alternatively, the at least one lifting floor is designed as the at least one holding means.

Preferably, at least one first set-up process is initially carried out, while the material sections are removed in isolated form from an investment stack and are subjected to trial work by means of the processing machine. The investment stack is preferably formed by a first set of material sections. The processing is preferably still unsuccessful in so far as the result of processing does not meet the requirements of finished finished products, for example, because in the case of a printing machine errors in the register or color register are still present. If the processing result is acceptable, a first subset of the first set of material sections is designated as waste. A subsequent second subset of the first set of material sections then consists of material sections which have been successfully processed with respect to the front, so-called provisional good sheets.

For example, for processing the rear sides of the material sections, it is of interest at which point in the first stack the separation between the first subset and the second subset is located.

Preferred is a method for operating at least a first

Processing machine for material sections of flat material, wherein a first amount of the material sections is collected after at least a first processing stage in a display of a processing machine in the form of a first stack and wherein at least a first mark is introduced into the first stack, the

Identifying a transition from a first subset of the first set of material sections to a second subset of the first set of material sections. The first stack or delivery stack is preferably subsequently turned, in particular by 180 ° and in particular about a horizontal axis. The first stack or delivery stack is fed to the first processing machine, which is preferably identical to that processing machine which already has the first processing machine Stack or stack of output. In a second machining operation, at least a second stack of material sections is preferably produced. Within the first processing machine, these material sections of this first stack are preferably singulated.

Preferably, at least a second set-up process is then carried out, while the material portions of the first subset of the first stack, in particular the former delivery stack and current investment stack taken occasionally and processed by the processing machine on a trial basis, especially on a back, so a side other than in the first machining operation. The first stack, in particular former delivery stacks and / or current investment stacks, is preferably further formed essentially by the first quantity of material sections. For example, there are no individual sheets that have been rejected for transport errors or damage to the material sections in the display or control withdrawals due to color settings or register settings or controls geometric content or the like. The processing in the second setup process is preferably also still unsuccessful insofar as the result of the processing does not meet the requirements of finished end products, for example, because in the case of a printing machine errors in the register or color register are still present. If the processing result in the second setup process is acceptable, another, third subset of the first set of material sections is specified as waste. Preferably, this further, third subset has only a small or more preferably no intersection with the second subset, which was formed from the material sections successfully processed in the first processing operation. A subsequent further, in particular fourth, subset of the first set of material sections then consists of material sections, so-called good sheets, which have been successfully processed both on the front side and on the rear side. For example, for further processing of the material sections, it may also be of interest at which point in the second delivery stack formed during the second processing operation Separation between third subset and fourth subset is, ie in particular between waste paper on the one hand and successfully on the front and back processed material sections on the other.

Preferably, at least one brand sensor associated and / or connectable with the processing machine and / or connectable detects, in particular in connection with the second setup process and / or the second processing operation, the at least one first marking. Preferably, as a reaction to the detection of the at least one first marking, at least one component of the first processing machine is set from a first operating state into a second operating state.
