Web- or sheet-like materials are used in the production of packaging. For example, sheets are imprinted, embossed, creased, perforated, die-cut, cut, stitched, glued and, for example, folded into packaging in multiple processing steps. To optimally utilize the surface area of a sheet, in general multiple identical or different copies, for example of a poster, a folding box or a packaging, are printed on a common sheet and then die-cut. These copies are referred to as multiple-up copies.
A sheet processing machine can comprise different processing steps, such as imprinting, cutting, embossing, creasing, die cutting, perforating, gluing and/or stitching. Such sheet processing machines frequently also comprise inspection devices. Sheets are typically processed and cut to size in processing machines using tool-dependent die cutting and cutting devices.
Such a processing machine is configured as a die cutting, cutting, perforating, embossing and/or creasing machine, for example. When such a processing machine is referred to hereafter as a die cutter and/or a die-cutting machine, in particular also a cutting, perforating, embossing and/or creasing machine is meant. In addition to rotary die cutters, tool-dependent systems also encompass flat die cutters, in particular flat-bed die cutters. In these, multiple sheets are processed consecutively by a cyclically recurring movement. The sheets are preferably moved substantially horizontally through the processing machine by way of a transport system, preferably a chain gripper system. In addition to a die-cutting unit, such a machine usually also comprises other units, such as a sheet infeed unit, a sheet delivery unit, a stripping unit, a sheet insert unit, a multiple-up separating unit and an offcut piece delivery unit. The sheet infeed unit is preferably configured to transfer sheets to the transport system. Additionally, sheets are, for example, aligned in the sheet infeed unit.

It is the object of the present invention to devise a sheet processing machine comprising at least one infeed system, and a method for controlling an infeed system of a sheet processing machine.
The object is attained according to the present invention by the at least one transport means being configured to move and/or to be movable and/or to be moved from an alignment position to a transfer position and/or back. The at least one transport means in the alignment position, at least during a rough alignment of sheets and/or during a lateral alignment of sheets, at least temporarily has the at least one mean state. The distance between the at least one upper holding surface and the at least one assigned lower holding surface, in the at least one mean state of the at least one transport means, in each case, is at least greater than the thickness of a sheet of the sheets to be transported. The at least one mean state corresponds to a holding down of sheets, which at least partially fixes the respective sheet in the vertical direction and/or which only allows a movement of the respective sheet in the transport direction and/or transverse direction, and the at least one transmission shaft is arranged eccentrically in at least one adjusting shaft. In some examples of the method herein, the at least one transport means is in the alignment position, at least during a rough alignment of sheets and/or during a lateral alignment of sheets, and at least temporarily has the at least one mean state. The distance between the at least one upper holding surface and the at least one assigned lower holding surface, in the at least one mean state of the at least one transport means in each case is at least greater than the thickness of a sheet to be transported. The position of the respective sheet, in the mean state, is fixed at least partially in the vertical direction. The respective sheet, in the mean state, is movable and/or is configured to move at least in the transport direction and/or transverse direction, and the at least one transmission shaft is eccentrically arranged in at least one adjusting shaft.
The advantages to be achieved with the invention are, in particular, that feeding of a respective, preferably at least one, sheet in a positionally accurate manner from an infeed unit to at least one unit processing the sheet is ensured by at least one infeed system. Advantageously, a sheet, preferably the at least one sheet, is aligned upstream from a transfer position, and is transferred in the transfer position by the at least one infeed system in an aligned manner to at least one downstream transport system Preferably, the at least one sheet is, more preferably at least twenty, more preferably at least fifty, more preferably a multiplicity of sheets are preferably consecutively aligned in the infeed system, and preferably consecutively transferred to the downstream transport system.
Positioning the, preferably at least one, sheet in an alignment position, in particular on at least two front lay marks, advantageously reduces and/or minimizes a position error of the sheet. The, preferably at least one, sheet is thus rough aligned, in particular with respect to its position relative to at least one transport means, preferably at least one gripper, of the at least one infeed system. In this way, the respective, preferably the at least one, sheet is advantageously held by the at least one transport means in a print-free region of the sheet, in particular subsequent to having been positioned, whereby the impact on a potentially present print image and/or the surface of the sheet is minimized while the sheet is being held and/or transported by the at least one transport means.
The, preferably at least one, sheet is advantageously finely aligned while it is transported from the alignment position to the transfer position The fine alignment is advantageously carried out at least with respect to a position error of the sheet, preferably at least with respect to a position error of the sheet in a transport direction of sheets and/or with respect to a skewed position of the sheet and/or with respect to a lateral position error, in particular in the event of a displacement of the sheet orthogonal to the transport direction of sheets. In particular, the infeed system is configured to finely align the at least one sheet. Advantageously, the at least one sheet is transported in an aligned manner to the processing units and is processed therein in its position which has preferably been aligned by the infeed system.
The sheet processing machine comprises at least one transport means of an infeed system. The infeed system preferably comprises at least one cam mechanism, each comprising at least one cam disk and an axis of rotation of the at least one cam disk. At least one scanning element is preferably arranged to rest against the at least one cam disk. The at least one scanning element is preferably connected to the at least one transport means via at least one drive lever. Each of the at least one drive lever preferably has at least one mounting point. The mounting point and the axis of rotation are preferably configured to be adjustable and/or to be adjusted and/or to adjust and/or are adjusted relative to one another. A position displacement of the mounting point relative to the axis of rotation is preferably configured to compensate for at least one position error of at least one sheet. Preferably, the relative position of the transport means of the infeed system of the sheet processing machine is changed. In this way, optimal feeding of the at least one sheet to a unit that processes the sheet is advantageously ensured.
The preferably at least one sheet is advantageously transported from the alignment position to a transfer position by at least one movement of the at least one transport means, preferably of the at least one gripper of the infeed system, along a transport path of sheets, in particular by at least one cam mechanism of the infeed system, more preferably by at least one dual cam mechanism of the infeed system. The at least one cam mechanism is advantageously connected to at least one drive shaft, which is driven by an in particular central drive of the sheet processing machine.
Advantageously, the at least one cam mechanism is configured as a dual cam mechanism, comprising at least two cam disks in each case, for the transport movement of the, preferably at least one, sheet. When a respective scanning element rests in each case against one of the cam disks of the dual cam mechanism, and at least two scanning elements are arranged on a preferably shared drive lever, preferably all scanning elements advantageously rest, preferably permanently, without clearance against the respective one, preferably the at least one, cam disk. The respective at least one further scanning element is preferably configured as a pressing element of the respective at least one scanning element.
The infeed system advantageously comprises at least two cam mechanisms, which are arranged parallel to one another in the transport direction, on at least one, preferably joint, drive shaft. This advantageously allows the driving torque to be simultaneously picked up from the at least one drive shaft. At least one servo drive is preferably assigned to each cam mechanism of the infeed system. The at least one servo drive advantageously intervenes in the at least one cam mechanism. The at least one servo drive advantageously intervenes in a conversion of the torque of the drive shaft into a preferably linear movement of the at least one transport means of the infeed system by the at least one cam mechanism.
Advantageously, at least one servo drive is activated and/or controlled by closed-loop control at least for compensating for a skewed position of the sheet. Advantageously, at least two servo drives are additionally activated and/or controlled by closed-loop control at least for compensating for a position error in the transport direction. In addition to a movement of the cam mechanism as a result of the drive of the processing machine, the at least one servo drive is preferably configured to drive, preferably move, the at least one transport means of the infeed system.
Advantageously, the at least one drive shaft and at least one holding element of a transport system downstream from the at least one transport means are preferably driven by way of the in particular central drive of the sheet processing machine and/or are mechanically or electronically connected to one another, whereby the at least one transport means and the at least one holding element, downstream therefrom, of the transport system are in particular synchronized and/or can be synchronized in terms of time. As a result of the at least one transport means and the at least one holding element, downstream therefrom, of the transport system being in particular synchronized in terms of time, a collision of the relevant components during a movement of the at least one transport means and/or of the at least one holding element of the transport system, in particular, for example, due to electrical malfunctions, with one another is prevented.
The sheet processing machine advantageously comprises at least one sensor device. Preferably, at least one infeed unit of the sheet processing machine comprises the at least one sensor device. The at least one sensor device preferably comprises at least two sensors. The at least two sensors are preferably configured as a camera, whereby preferably both an edge and a printing mark can be detected. Advantageously, the respective, preferably the at least one, sheet is detected in the alignment position by at least one sensor, preferably at least two sensors, in particular at least three sensors. The at least two sensors are preferably configured to detect, and/or detect, at least one edge and/or printing mark of the at least one sheet of the sheets. Advantageously, at least two sensors are arranged parallel to one another and orthogonally to the transport direction and detect at least one leading edge of the sheet in the alignment position. For example, as an alternative or in addition, the at least two sensors detect at least one printing mark of the at least one sheet. The at least two sensors preferably selectively detect, and/or are configured to detect, an edge, preferably a leading edge, and/or at least one printing mark of the at least one sheet. The sheet processing machine, preferably the at least one infeed unit, preferably comprises the at least one infeed system. The at least one sensor device is preferably configured to control by open-loop control and/or closed-loop control at least one servo motor of the infeed system, preferably as a function of the detection of at least one sheet of sheets by the at least two sensors. The ascertained measurement value is advantageously fed to a control system, which controls by closed-loop control and/or open-loop control at least one component of the sheet processing machine, in particular at least one servo drive, as a function of the detected sheet. Advantageously, at least one servo drive is actuated as a function of the preferably selective detection. Advantageously, at least one component of the sheet processing machine is controlled by open-loop control and/or closed-loop control.
A detection of the sheet by the at least two sensors in the alignment position advantageously takes place so that the detection zone of the respective, preferably the at least one, sensor has an edge of the sheet and, additionally or alternatively, a printing mark of the sheet. In this way, advantageously both an edge of the sheet and a printing mark of the sheet are detected and/or detectable by the respective, preferably the at least one, sensor. In this way, advantageously both an edge of the sheet and a printing mark of the sheet are detected and/or detectable by the respective, preferably the at least one, sensor, without changing a position of the sensor and/or without changing a position of the detection zone. Advantageously, at least one sensor, for example a third sensor, is arranged so as to detect at least one side edge of the sheet in the alignment position. Advantageously, at least one sensor of the at least two sensors is configured in each case to detect and/or determine the position in the transport direction of the at least one sheet and the position in the transverse direction of the at least one sheet. In this way, the position of the sheet in the transport direction and in the transverse direction and a skewed position of the sheet can preferably be ascertained and/or are ascertained by the at least two sensors. This advantageously allows further sensors and/or a lateral stop, intended to align the sheet in the transverse direction, to be dispensed with. At least one sensor of the at least two sensors is advantageously configured to detect at least one printing mark, the at least one printing mark being integrated into at least one print control strip. This is preferably a space-saving configuration since a larger surface area of the sheet is available for multiple-up copies.
The sheet processing machine comprises the at least one infeed system, wherein the at least one infeed system comprises the at least one transport means including, in each case, at least one upper holder and, in each case, at least one lower holder. The at least one transport means in each case can be arranged and/or is arranged in at least three states. A maximally closed state corresponds to a minimal distance, and a minimally closed state corresponds to a maximal distance, and an at least one mean state corresponds to at least one mean distance between at least one upper holding surface at least of the respective upper holder of the at least one transport means and at least one lower holding surface of the lower holder of the at least one transport means which is assigned to the respective upper holder. The at least one transport means has the minimally closed state at least once, and the maximally closed state at least once, and the at least one mean state at least once, during a machine cycle. The at least one transport means is arranged in the minimally closed state at least once, and in the maximally closed state at least once, and in the at least one mean state at least once, during a machine cycle.
The at least one transport means, preferably the at least one gripper of the infeed system, comprises in each case at least one pivoting and/or pivotable holder. The at least one transport means, preferably the at least one gripper of the infeed system, comprises in each case at least one pivoting and/or pivotable holder so that a distance between at least one upper holder and at least one lower holder of the at least one transport means is settable and/or set, in particular via at least one cam mechanism. The at least one upper holder advantageously has at least a mean distance with respect to the at least one lower holder of the at least one transport means while the sheet is being positioned in the alignment position. At a mean distance between the at least one upper holder and the at least one lower holder, the sheet is at least partially fixed at least in one spatial direction, in particular at least in the vertical direction. This advantageously enables positioning and/or a rough alignment within the transport path in the alignment position, preferably at least in the transverse direction and/or in the transport direction, wherein the sheet is at least partially, preferably completely, fixed with respect to its vertical position. The at least one mean distance is advantageously set and/or settable to a maximum thickness of the sheets to be transported. The mean distance is preferably settable for each sheet so that, in each case, at least partial fixation in the vertical direction exists while the respective, preferably the at least one, sheet is being positioned in the alignment position, and the respective, preferably the at least one, sheet at least partially has freedom of movement in the transport direction and/or orthogonal to the transport direction.
The distance between the at least one upper holder and the at least one lower holder is advantageously varied by at least one cam disk being scanned by at least one scanning element. Using a transmission shaft, which is eccentrically mounted in an adjusting shaft, the mean distance between the at least one upper holder and the at least one lower holder is advantageously set. The axis of rotation of the transmission shaft is advantageously adjusted relative to the axis of rotation of the adjusting shaft, preferably prompted by at least one servo drive, whereby the preferably upper holder and/or the lower holder are advantageously raised and/or lowered. Advantageously, the position of a scanning element at the at least one cam disk is preferably virtually not influenced by an adjustment of the axis of rotation of the transmission shaft relative to the axis of rotation of the adjusting shaft.

A sheet 02 to be transported by the infeed unit 200, preferably the at least one sheet 02, for example, has at least one position error when arriving at the alignment position PA. The position error of a sheet 02 describes a deviation of its positioning along the transport path relative to a target positioning. This is the case, for example, in the case of a position error in the transport direction T when the time at which the leading edge 07 and/or at least one printing mark 11 of the sheet 02 actually arrive at the alignment position PA deviates from an expected and/or required time at which the leading edge 07 and/or at least one printing mark 11 of the sheet 02 arrive. For example, if a sheet 02 arrives at the alignment position PA at a later time than expected and/or required, its leading edge 07 and/or the relevant at least one printing mark 11 are situated upstream from the expected and/or required position in the transport direction T at the expected and/or required time. For example, a position error of the sheet 02 also exists in the case of a skewed position of the sheet 02. In the case of a skewed position of the sheet 02, for example, its leading edge 07 has an angle of greater than 0° (zero degrees) with respect to the transverse direction A and/or its side edges 09 have an angle of greater than 0° (zero degrees) with respect to the transport direction T. In the case of a skewed position of the sheet 02, at least two printing marks 11 arranged parallel to and spaced apart from one another along the leading edge 07 of the sheet 02 have different coordinates along the transport direction T. In this way, at least one of the relevant printing marks 11 is arranged upstream from the respective, at least one further printing mark 11 in the transport direction T. An in particular lateral position error also exists when the sheet 02 is arranged displaced with respect to its expected and/or required position in the transverse direction A.

A sheet 02 is preferably fixed during the rough alignment, at least in the vertical direction V, in particular by the at least one transport means 204.

In addition, or as an alternative, the respective, preferably the at least one, sheet 02 is more preferably finely aligned by adjusting, preferably pivoting, the mounting point S and the axis of rotation D relative to one another. As a result of the fine alignment of the sheet 02, it is ensured that the sheet 02, in the transfer position PU, is transferred, while maintaining register accuracy, to the at least one holding element 1202 of the transport system 1200. The relative position of the at least one transport means 204 is preferably changed during the alignment of the sheet 02.

The at least one servo drive 218 preferably generates a larger relative displacement of the mounting point S and of the axis of rotation D with respect to one another than a further servo drive 218, which is preferably activated and/or controlled by closed-loop control at the same time. The at least one servo drive 218 is preferably configured to be activatable and/or to be activated and/or to be controllable by closed-loop control and/or to be controlled by closed-loop control at least during a compensation for a skewed position of the sheet 02.

For example, the at least one coupler 216 comprises at least one self-aligning bearing for this purpose. The respective sheet 02 is preferably adjusted horizontally and orthogonally to the transport direction T, as a function of the preferably selective detection of the at least one printing mark 11, preferably of the at least one lateral printing mark 11 and/or the at least one side edge 09 of the sheet 02.
