Description
- This application is a Continuation of International Application No. PCT/EP2014/055968, filed on Mar. 25, 2014, and for which priority is claimed under 35 U.S.C. §120. PCT/EP2014/055968 claims priority under 35 U.S.C. §119(a) to Application No. 13161057.8, filed in Europe on Mar. 26, 2013. The entire contents of each of the above-identified applications are hereby incorporated by reference into the present application.
- 1. Field of the Invention
- The present invention relates to a sheet handling apparatus having a sheet input section, a sheet processing section, a sheet output section, a conveying mechanism adapted to convey sheets from the input section through the processing section to the output section, and a controller for the conveying mechanism.
- 2. Description of Background Art
- An example of a sheet handling apparatus of this type is a stand-alone scanner in which the processing section includes a scanning head for scanning an image that is present on the sheet. A printer may be mentioned as another example.
- An alternative type of sheet handling apparatus has a combined input and output section, and the conveying mechanism is adapted to convey the sheets from the input section to the processing section and, after processing, back from the processing section to the combined input and output section. This has the advantage that the operator may collect the processed sheets from the same side of the machine from which he has fed the sheets into the machine. On the other hand, this type has the drawback that the throughput is slightly reduced because the time needed for rewinding the processed sheet back to the input and output section delays the time at which the next sheet can be fed in.
- It is an object of the present invention to provide a sheet handling apparatus in which sheets, in particular sheets of different formats, can be handled reliably and efficiently.
- According to the present invention, the controller is adapted to be switched between a feed through mode in which the sheets are output by being fed through from the processing section to the output section, and a rewind mode in which the sheets are output by being fed in a reverse direction from the processing section back to the input section.
- In this apparatus, sheets which have a relatively small format may be handled in the rewind mode, which is most convenient for the operator. On the other hand, when processing a large format sheet, in particular a sheet which has a large dimension in the transport direction, it would be time-consuming to rewind the sheet to the input section. In this case, the apparatus may be switched to the feed through mode, so that the processed large format sheets will be output by feeding them forward to the output section in the same direction in which the sheets are fed in. As a consequence, a plurality of large format sheets may be fed through in close succession, so that a high throughput may be obtained.
- The present invention is particularly advantageous for apparatus that are designed for handling sheets with formats that vary in a large range, e.g. from A0 to A4. Then, the output section, which will be needed only for large format sheets does not have to be designed for handling small format sheets, which permits a low-cost design. The small format sheets, which will be rewound towards the input section can readily be taken out by the operator, so that the input section is not required to be capable of reliably guiding and collecting the small format sheets.
- More specific optional features of the present invention are indicated in the dependent claims.
- In a particularly preferred embodiment, the controller has a format information processing section capable of automatically selecting the mode of operation of the conveying mechanism dependent upon the format of the sheets. Preferably, the apparatus further has a sensor system capable of detecting the format of the sheets that are being fed or have been fed into the processing section, so that the detection of the sheet format and the selection of the mode of operation may be automated. In case of a scanner, the sensor system for the format detection may be formed by or incorporated in the scanning head.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the present invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from this detailed description.
- The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
-
FIG. 1 is a schematic side elevational view of a sheet handling apparatus according to the present invention; -
FIG. 2 shows the sheet handling apparatus ofFIG. 1 in a top plan view; -
FIG. 3 is a top plan view analogous toFIG. 2 but illustrates the handling of small format sheets; -
FIG. 4 is a flow diagram of a decision process that is performed in a controller of the sheet handling apparatus; and -
FIG. 5 is a side elevational view of a sheet handling apparatus according to a different embodiment of the present invention. - The present invention will now be described with reference to the accompanying drawings, wherein the same reference numerals have been used to identify the same or similar elements throughout the several views.
- As an example of a sheet handling apparatus,
FIG. 1 shows ascanner 10 adapted to electronically scan images that are carried onsheets scanner 10 has abase part 16, and abridge part 18 between which asheet transport path 20 is formed through which thesheets input section 22 via aprocessing section 24 to anoutput section 26. - The
input section 22 is formed by a slanting part of the top surface of thebase part 16 on one side of thebridge part 18 and by a number of projectingcurved guide bars 28 for thesheet 12. Theprocessing section 24 includes ascanning head 30 that is accommodated in thebridge part 18 and extends over the entire width of the apparatus so as to scan the sheets on their entire width when they are passed through. Theoutput section 26 is formed by a cage that is designed to collect thesheets 14. As in the example shown, the cage-like output section is formed by one or more bent wires, which defineguide rails 32 for limiting the cage in a lateral direction and at its free end, as well as asupport part 34 for guiding and supporting thesheet 14 in the vicinity of its width-wise center. - Both the
base part 16 and thebridge part 18 accommodate parts of aconveying mechanism 36 which, in the example shown, has two pairs of motor-drivenconveying rollers 38. - An
electronic controller 40 controls thescanning head 30 and theconveying mechanism 36 and also processes the image information received from thescanning head 30. - Of course, the
scanning head 30 is not only capable of reading the image information carried on thesheets information processing section 42 of thecontroller 40 so as to automatically determine the format, i.e. the length in a transport direction and the width in a lateral direction, of the sheet that is being conveyed past the scanning head. - In the example shown in
FIGS. 1 and 2 , thesheets output section 26 are configured such that thelarge format sheet 14 can reliably be guided and supported in the cage. The formatinformation processing section 42 of thecontroller 40 has detected the format of thesheet 14 and has, in particular, measured the length of the sheet when the trailing edge thereof has passed thescanning head 30. Based on this information, thecontroller 40 has controlled theconveying mechanism 36 such that theconveying rollers 38 continue to rotate in the same direction, so that thesheet 14 is output by being fed through to theoutput section 26. - For comparison,
FIG. 3 illustrates a case where asheet 12 a with a relatively small format, e.g. A4, is fed in at theinput section 22. It can be seen here that, in comparison to the format of thesheet 12 a, the cage forming theoutput section 26 has voids that are so large that thesheet 12 a would most likely drop out if one attempted to collect thesheet 12 a in the output section. However, in this case thecontroller 40 has detected that thesheet 12 a has only a small format and therefore controls theconveying mechanism 36 such that, once the trailing edge of the sheet has passed the scanning head, the direction of rotation of theconveying rollers 38 is reversed, so that thesheet 12 a is rewound towards theinput section 22, as has been indicated by arrows inFIG. 3 . - The
sheet 12 a can readily be taken out by the operator who has fed in this sheet. Since the length of thesheet 12 a is relatively small, the time that is needed for rewinding and returning the sheet to theinput section 22 is negligible and does not significantly reduce the throughput of the apparatus. - And as is further shown in
FIGS. 2 and 3 , thebridge part 18 of the scanner has acontrol panel 44 permitting the operator to input settings and instructions, including settings for the mode of operation of theconveying mechanism 36. In a preferred embodiment, the operator may select between a fed through mode in which all sheets, regardless of their size, are always output towards theoutput section 26, a rewind mode, where all sheets are always output by being returned to theinput section 22, and an automatic mode in which the mode of operation is decided upon automatically, depending upon the detected format of the sheets. - When the automatic mode has been selected, the
controller 40 performs an algorithm that has been illustrated inFIG. 4 . In a step S1, the sheet is drawn in from theinput section 22. Then, when the trailing edge of the sheet has just passed thescanning head 30, thecontroller 40 reads the format of the sheet, especially the length of the sheet in the transport direction, in step S2. Then, in step S3, it is decided whether or not, the format (length) of the sheet is larger than a certain threshold value (max_rewind). For example, this threshold value may be set to about 30 mm, corresponding to the length of an A4-sheet supplied in portrait orientation and the length of an A3-sheet supplied in landscape orientation. When it is decided that the format is larger than max_rewind, the sheet is fed forward to theoutput section 26 in step S4. Otherwise, it is rewound to theinput section 22 in step S5. - The present invention is not limited to a sheet handling apparatus with the physical configuration shown in
FIGS. 1 to 3 . For example, as is shown inFIG. 5 , thesheet transport path 20 may be curved, so that theinput section 22 and theoutput section 26 may be disposed on the same side of thebase part 16. Nevertheless, although the sheets are always delivered on the same side, there is a distinction between the mode in which the sheets are fed through thetransport path 20 into theoutput section 26 and the mode of operation in which they are returned to theinput section 22. - If the sheet handling apparatus is a scanner, the
scanning head 30 may be disposed on either side of thetransport path 20. In the example shown inFIG. 5 , it is disposed on the bottom side, so that the sheets have to be supplied face-down. However, it should be understood that the scanner inFIG. 5 could be disposed on the top side as well. - The present invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
