Definitions

  • the invention relates to a method of stacking printed sheets on a pallet, to a sheet printer, to a computer program, and to a computer-readable medium.
  • a sheet printer may comprise a stacker at an end of a transport path of the printer.
  • the stacker may be configured to hold a pallet and to form a stack of printed sheets thereon.
  • Such a stacker is known from e.g. US5669755A .
  • the stacks of printed sheets are generally transported on their respective pallets to a finisher for processing the sheets into print products, such as books, leaflets, etc.
  • Certain finishers allow the stack to be loaded with its pallet into the finisher. These finishers commonly require that the edge of the stack is positioned at an edge of the pallet, as otherwise a separator in the finisher is unable to engage the sheets and separate these from the stack.
  • Sheet printers generally position the stack on the pallet spaced apart from the pallet's edges due to restrictions in the stacker.
  • sheet printers may comprise a registration unit for adjusting an position and/or orientation of a sheet on the transport path, as for example disclosed in EP3896019B1 .
  • a method of stacking printed sheets on a pallet according to claim 1, a printer according to claim 9, a computer program according to claim 14, and a computer-readable medium according to claim 15 are provided.
  • the method comprises the steps of:
  • At least one edge of the pallet is at the predetermined pallet edge position in the stacker. Inside the printer's position of the sheet is compared to the pallet edge position and the sheet is controlled, so that inside the stacker it is in the pallet edge position. In consequence, the sheet is stacked in the stacker directly at an edge of the pallet. Thereby, the stack is formed at said edge of the pallet.
  • the stack on the pallet is thus directly suited for use by a finisher. By forming the stack directly on an edge of the pallet no additional re-positioning steps of the stack on the pallet after stacking are required. Thereby, the object of the present invention has been achieved.
  • the first direction is a lateral direction perpendicular to the transport direction of the sheet.
  • a lateral edge of the sheet is then positioned at the pallet edge position.
  • the edge of the pallet defining the pallet edge position is at the same side of the pallet as said edge of the sheet.
  • the lateral edge of the pallet is preferably further aligned, so that it is parallel to the transport direction of the sheet.
  • the method comprises the steps of:
  • the position of the pallet's edge is stored on a memory of a printer's controller as a pallet edge position parameter or setting.
  • the sheet's position inside the printer is determined at one or more points. This position is compared to the pallet edge position parameter or setting. Inside the printer the sheet is controlled based on said comparison, so that the sheet will be stacked at the pallet edge position.
  • the stacker comprises a pallet holder with an aligner, which defines the pallet edge position.
  • the aligner defines an end position for the pallet in at least the lateral direction. This position is relative to the registration unit, which is applied for positioning the sheet at the pallet edge position.
  • the pallet edge position defines the pallet edge position parameter or setting.
  • the aligner may be adjustable is which case the controller applies a pallet edge position parameter, which is updated based on a changed position of the aligner. In case the aligner defines a substantially fixed position for pallets during stacking, then the controller applies a pallet edge position edge setting.
  • the sheet is moved into the pallet edge position before stacking.
  • the sheet may be re-positioned on the transport path of the printer at the lateral position of a selected edge of the pallet, while the sheets are moving towards the stacker, for example using a registration unit provided in the printer.
  • the method further comprises the step of positioning a pallet in a stacker with one of its edges in the pallet edge position in the lateral direction. During stacking both the pallet's edge and the corresponding edge of the sheets are at the pallet edge position. A pallet is thus loaded into the stacker, so that its edge is at the pallet edge position.
  • the step of positioning the pallet comprises positioning the pallet at an aligner of a pallet holder on a pallet support of a stacker. Additionally, the pallet's edge may be aligned so that it is aligned with a second direction preferably perpendicular to the first direction.
  • the first and second directions are preferably horizontal, wherein the edge of the pallet is positioned at a predefined lateral position and preferably extends substantially parallel to the transport direction of the sheet.
  • the stacker may comprise a stack holder with an aligner, so that when loaded the stack is securely held aligned with the pallet edge position during the stack forming.
  • the edge of the sheet to be positioned at the pallet edge position is the respectively same edge of that of the pallet positioned at the pallet edge position in the lateral direction.
  • the same respective edge of the pallet is positioned at the pallet edge position as the sheet.
  • the edge is a lateral edge with respect to a main transport direction of the sheet.
  • the left edge of the sheet is then positioned at the left edge of the pallet, or its right edge at the right edge of the pallet.
  • leading or trailing edge of the sheet is positioned respectively at the leading or trailing edge of the pallet.
  • the step of positioning the sheet comprises shifting the sheet perpendicular to its transport direction into the pallet edge position.
  • the sheet is shifted laterally. In case the first direction is the lateral direction, this positions the sheet at the pallet edge position.
  • the method further comprises the step of selecting one of the lateral sides of the pallet for positioning the edges of the sheets at.
  • the edge of pallet can be aligned at either lateral edge of the pallet. For each print/stack job, a different, lateral edge of the pallet can be selected, for example to aid the operator to distinguish between print jobs or for logistical reasons.
  • the pallet edge position is selected to be at one of the lateral edges of the pallet.
  • the registration unit is then controlled to align the sheets with the selected lateral edge of the pallet.
  • the step of positioning the sheet is performed after a step of printing on the sheet and before the step of stacking the sheet, and wherein after the step of positioning the sheet, the sheet is transported to the stacker while maintaining its respective edge in the pallet edge position in the lateral direction.
  • the first direction is the lateral direction.
  • the sheet is positioned at the pallet edge position after the printed image has been fixed on the sheet.
  • the position adjustment may e.g. be performed by a registration unit positioned between the stacker and the printhead assembly.
  • the sheet is then transported to the stacker while maintaining its respective edge at the pallet edge position.
  • the sheet may be registered upstream of the printhead assembly, so that it maintains its position in the pallet edge position as passes the printhead assembly for printing and moves to the stacker.
  • a further aspect of the invention relates to a sheet printer comprising:
  • the printer is configured to perform the method according to any of the embodiments described above.
  • the pallet is loaded in the stacker, so that its respective edge is at the predetermined pallet edge position.
  • the sheet is then controlled so it lands on the pallet or the stack thereon with its corresponding edge at the pallet edge position.
  • the position of the sheet is adjusted by the registration unit, which registration unit is preferably along a transport path of the printer.
  • the registration unit is positioned upstream of the stacker and configured to adjust a position and/or orientation of the sheet on the transport path of the printer.
  • a registration unit is configured to position one lateral edge of the sheet at the pallet edge position in the lateral direction. As the sheet then travels further in the transport direction, said edge of the sheet remains in the pallet edge position until it arrives at the stacker.
  • the registration unit also orients the one lateral edge substantially parallel to the transport direction of the sheet.
  • the stack holder comprises an aligner for aligning the edge of the pallet into the pallet edge position in the lateral direction, preferably wherein the aligner comprises at least one urging element for driving the pallet against at least one an pallet alignment stop.
  • the aligner ensures that the pallet's edge is and remains at the pallet edge position during stacking.
  • the aligner ensures rapid and easy loading of a new pallet by simplifying the aligning of the pallet's edge.
  • the aligner thus defines a during use and/or stacking fixed point in space, which defines the pallet edge position. This allows the pallet edge position to be applied by the controller as a pallet edge position parameter or setting, so that sheets can be accurately aligned thereto and thus to the actual pallet edge position.
  • the controller on its memory stores a pallet edge position setting or parameter corresponding to the pallet edge position in the lateral direction, wherein the controller is configured to control the registration unit based on comparison between the pallet edge position setting or parameter and a determined position of the sheet on the transport path.
  • the pallet edge position corresponds to a physical location in the printer, for example defined by an aligner for the pallet.
  • the pallet edge position setting or parameter is applied during the sheet registration, so that the edge of the sheet will be at the physical pallet edge position, after stacking. The sheet may be brought into said position before stacking.
  • the lateral direction is perpendicular to a transport direction of the transport path and a during use vertical direction.
  • the pallet is positioned so that its respective edge is at a predefined position in the lateral direction.
  • said edge is further parallel to a main transport direction of the sheet.
  • the registration unit then shifts the sheet, so that its lateral edge on the same side of the respective edge of the pallet has the same lateral position as the pallet's edge, so that by transporting the sheet further it arrives at the stacker at said same lateral position.
  • the lateral position is relatively to a center of the transport path.
  • the registration unit is downstream of a printhead assembly, so that the sheet is moved into the pallet edge position after printing.
  • the transport path is arranged to transport the sheets in the transport direction from the registration unit to the stacker while maintaining the respective edge of the sheets at the pallet edge position in the lateral direction.
  • the transport path is formed by a transport mechanism comprising e.g. transport pinches, vacuum belts, and/or vacuum drums.
  • the controller is further configured to select one of the lateral edges of the pallet for aligning a sheet stack thereon, and is further configured to control the registration unit to align the sheets at the selected lateral edge of the pallet for forming said sheet stack.
  • the registration unit is arranged to align the sheet with either lateral edge of the pallet. For each print/stack job a lateral edge of the pallet is selected, either based in the print job information or by a default setting in the controller's memory. Dependent on this selection, the controller selects a pallet edge position setting or parameter corresponding to the left or right edge of the pallet. The controller then controls the registration unit to position the corresponding left or right side of the sheets at the selected edge of the pallet.
  • the present invention further relates to computer program comprising instructions to cause the sheet printer as described above to execute the steps of the method as described above.
  • the present invention additionally relates to a computer-readable medium having stored thereon the above mentioned computer program.
  • Fig. 1 illustrates a sheet printer 1.
  • An input module 4 on the right side comprises one or more input stack supports 2 supporting at least one stack 3 of sheets. Individual sheets are separated from the stack 3 by the input module 4, which places the sheets on an input path of the printer 1.
  • the input module 4 may comprise a separator to separate individual sheets from the stack 3.
  • the input path brings the sheets to a print path section, illustrated as a straight, linear path, where the sheet is processed for printing thereon.
  • the print path section comprises a switch 5 positioned at an intersection of the input path and a duplex path, which duplex path is arranged to return printed sheets to the print path. Sheets on the print path can thus be a mix of unprinted or one-side printed sheets.
  • the print path comprises a first registration unit 6 downstream of the switch 5.
  • the first registration unit 6 comprises a first sheet detector 5 for detecting a position and orientation of each sheet.
  • the orientation of the sheet is e.g. the angle of its forward facing or leading edge with respect to the transport direction X.
  • the first registration unit 6 controls its registration drive 7 to position the sheet to a predefined position and/or align the sheet to a predefined orientation, for example with its leading edge perpendicular to the transport direction X, so that it will be parallel to the printhead assembly 10.
  • the registered sheet subsequently passes by a coater 9, which applies a liquid coating on at least a portion of the treated surface.
  • the coater 9 may for example comprise an array of printheads configured to jet droplets of coating liquid or comprise a roller for transferring coating liquid as the roller rolls over the sheet. Any suitable coating liquid may be applied, such as for example Canon ColorGrip.
