Abstract
A device is provided for holding one or more stacks of sheets, especially stacks of sheets that are stored offset to each other, for example by offset collating, that are output to an output station by a sheet processing device. According to an aspect of the invention, the device consists of a portable container that can be placed at the output station of the sheet processing device, which has a horizontally aligned stacking floor, two upright side walls that are opposite each other and an upright impact wall that is arranged downstream of the sheet output device for the stack of sheets.
Description
- The invention relates to apparatus and methods for holding one or more stacks of sheets, especially stacks of sheets that are placed so that they are offset from each other (so-called offset collating), that are output to an output station by a sheet processing device.
- There are sheet processing devices, called finishers, that process sheets of specific sizes, e.g. the formats DIN A4 and DIN A5, and also carry out specific processes on the sheets, e.g. center and Z-folds, but that do not have any equipment to punch, bind, staple, etc. the stacks of sheets that are output. Further processing procedures of this type must be carried out on other devices. This makes it necessary to take the loose stack of sheets placed at the output station of the sheet processing device and manually transport it to a further processing device. This involves the danger that the sheets in a sheet stack that are placed so that the edges match will slip around and that individual, or even several, sheets of the stack of sheets that has been placed will become disordered and will have to be aligned again before further processing. This procedure takes a lot of time and is not cost-effective.
- According to an aspect of the invention, an apparatus and method are provided for handling stacks of sheets. According to a preferred embodiment, transport of loose sheets is allowed without disturbing the stack of sheets.
- Further characteristics and advantages can be found in the description of an embodiment of the invention and the other subclaims. The drawings show:
- FIG. 1 presents a container according to an aspect of the invention that is placed on the slanted output station of a sheet processing device, in cross section;
- FIG. 2 The container according to FIG. 1 in graphical representation; and
- FIG. 3 The container according to FIG. 2 in its freely hanging transport position when lifted off the output station, in cross section.
- Various aspects of the invention are presented in FIGS.1-3, which are not drawn to scale, and wherein like components are numbered alike. Referring now to FIG. 1, a
sheet processing device 10, for example a finisher, has aslanted output station 11 that can be adjusted in height compared to anoutput slot 13, depending on the height of the stack ofsheets 12 placed on it. Thesheets 12 may be edge aligned. Theoutput station 10 can be adjusted laterally in order to be able to place complete stacks ofsheets 12 at an offset to each other so as to delimit them. These movements of the output station are generated by electrical drives that are not shown which drive theoutput rollers 14 according to methods and apparatus known in the art. - Certain sheet processing devices combine individual printed sheets into ordered stacks of sheets, and then place them in stacks at an output station prior to final processing. The final processing, for example punching, stapling, binding, etc., may be carried out on a different processing device. The stored stacks of sheets may be manually transported to the different processing device, but the stacks of sheets may become disordered during transport.
- According to an aspect of the invention, the sheets are kept ordered by a
portable container 15 that can be placed at theoutput station 10. Thecontainer 15 comprises astacking floor 16 and twoside walls 17 that are upright and opposite from each other and animpact wall 18 between theside walls 17 and positionable downstream from the output, for example, opposite the open side ofcontainer 15. The stack ofsheets 12 rests upon thestacking floor 16. - As can be seen in FIG. 2, an opening19 may be provided that extends down to the
stacking floor 16 between theimpact wall 18 and at least one of the twoside walls 17. The opening 19 serves as a pass-through for a hold-down device 20, each of which may be linked to aprojection 21 attached to thecontainer 15, or other suitable structure. Theprojection 21 may be part of asupport 22, attached to thecontainer 15. Theprojection 21 may be an angled end of thesupport 22 that extends into the inside of thecontainer 15. Two or moresuch openings 19 and hold-down devices 20 may be provided. - The
support 22 may connected rigidly to theside walls 17 and to theimpact plate 18 and stabilizes same. The support may be a U-shaped strap that is essentially horizontal when thecontainer 15 rests on theoutput station 11. - The hold-
down devices 20 may be a flexible plastic material and lie on the top sheet at both ends of a stack of sheets in order to prevent arching of the top sheets and thus avoid difficulty in placing the next stack of sheets. Theholddown device 20 may generate a predetermined contact pressure on the top sheets in a stack of sheets within thecontainer 15. - The
container 15 preferably comprises at least onecarrying handle 23 having ahandle surface 24 that runs at an acute angle to thestacking floor 16, or other suitable structure for lifting thecontainer 15. Thecontainer 15 may be lifted by thehandle 23 off or away from theoutput station 11 wtih thecontainer 15 in a tipped position such that the stack ofsheets 12 is supported uponimpact wall 18 and safely stays in position during transport, as best shown in FIG. 3. Thecontainer 15 may be tipped to a position wherein thestacking floor 16 is not horizontal. At least one of theside walls 16 may have ahandle 23. In the embodiment of FIG. 2, the free upper ends of theside walls 17 form a pair ofcarrying handles 23. - As shown in FIG. 1,
output station 11 may be arranged in a slanted position insheet processing device 10. For this reason,container 15 has asupport foot 25 at the processing device end of itsstacking floor 16, which is designed as a right angle in the embodiment shown, and is positioned to rest on theoutput station 11. - One side of the
support foot 25 may contact theoutput station 11 and the opposing side may contact the front wall ofsheet processing device 10. The vertical length of thesupport foot 25 may be dimensioned in such a way that when thecontainer 15 is placed on theoutput station 11, thestacking floor 16 of thecontainer 15 is horizontal. Thesupport foot 25 may extend across the width of saidstacking floor 16 at an angle thereto - A design such as this of
support foot 25 and its contact on the front wall of thesheet processing device 10 also secures the position ofcontainer 15 on theoutput station 11. - Although the invention has been described and illustrated with reference to specific illustrative embodiments thereof, it is not intended that the invention be limited to those illustrative embodiments. Those skilled in the art will recognize that variations and modifications can be made without departing from the true scope and spirit of the invention as defined by the claims that follow. It is therefore intended to include within the invention all such variations and modifications as fall within the scope of the appended claims and equivalents thereof.
