Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 According to the present invention, when the pages of the calendar are collated by the collating machine, the calendar pages for each month, which are sequentially sent out from the paper tray on which the calendar page bundles for each month are placed, have the wrong page order. In this case, the invention relates to a device for preventing misalignment of a calendar collator, which can immediately stop the operation of the collator and prevent misprints.

[0002]

[Prior art]

 Conventionally, when collating each month page of a calendar, a stack of calendar pages for each month from January to December is placed on each paper tray of the collating machine. , From each of these calendar page bundles, pull out one calendar page in order to the front page feed section and arrange them in monthly order.

At the stage before placing a stack of calendar pages stacked monthly on the paper tray of this collator, the printed and cut monthly calendar pages are carried around the collator. January is January, February is February, and so on. The heaps are piled up by month, and as the collating work by the collating machine progresses, the worker picks up from the pile of piles on the paper receiving stand of the collating machine. Stacked stacks with a height of about 10 to 15 cm are taken out and supplied so that they can be sequentially placed on the paper tray of the collator.

[0006] Thus, all the work of placing the stack of calendar pages on the collator is manually performed, but the operator does not count the exact number of stacks each time. For example, when part of the stack was temporarily placed on the workbench around the collator due to too many stacked bundles for February during the bundle supply operation, this unbalanced portion is left. There is no problem if G returns to the top of the mountain group for February, but mistakenly returns the unloaded amount for this February to the mountain group for March, or the unloaded amount for this February. Human error often occurs, such as placing the unloaded April portion that occurred in the same way on top of the minute portion.

In this way, once the page bundles for different months are stacked, the layer bundle and the layer bundle newly taken out from the pile group are judged to be for the months on the surface in appearance. If, for example, April is on the surface of the layered bundle, the layered bundle is placed in the collator even though February of the layer is partially mixed. It may be placed on the paper tray for a month. Of course, if you overlook such mistakes and proceed with work with the collator, February pages will be supplied while pages for April pages are being supplied, and misalignment will occur without realizing it. Will end up.

[0006] Conventionally, as a means for solving the problem due to the mis-stacking of page bundles on such a calendar collating machine, a printing surface of an arbitrary part such as a design or a photograph printed on a calendar page is used, This partially specified print area is imaged by an image sensor equipped with a photoelectric conversion element and a lens, and the lightness and darkness of the image and the light and shade of the color are recognized as a pattern, and the image is printed at the same position on the pages sequentially sent. Judgment is made as to whether the light / dark pattern of the print area or the shade pattern of the color matches the previously stored light / dark pattern or the shade pattern of the color, and if the pattern is different, the irregular signal is issued. Things are known.

[0007]

[Issues to be solved by the invention]

 In this way, in the detection method in which an arbitrary partial printing area on the printing surface is used as a detection unit and the lightness and darkness of the detection unit and the shade of color are recognized as a pattern, the stacking stacks placed on the paper trays of the collator are If the edges of each calendar page are aligned evenly from top to bottom without any unevenness, such as the cut edge of the stack immediately after cutting, for example, the light and shade of the detector on all pages for February There is no problem because the sensor can recognize the light and shade of color as the same pattern.

However, as described above, the stack of calendar pages arranged on each paper tray of the collator is placed manually by the operator, and the calendar pages of the stack are placed on the paper tray from above. It is extremely difficult to place all the sheets so that they are all aligned accurately and evenly up to the bottom. Therefore, in some areas, the upper and lower calendar pages may be offset from each other. In this case, the collating machine recognizes that the pattern of light and darkness and color tone of the detection unit detected by the sensor is different from the pattern of light and darkness and color tone of the detection unit stored in advance, and There is a problem in that malfunctions that often stop occur frequently.

Further, such a difference in pattern recognition by the sensor is more likely to occur when each calendar page is moving at a high speed, and thus the page stack error detection means by this method is erroneous. Since the collator frequently stops, it has a problem that it cannot be used practically.

[0010]

[Means for Solving the Problems]

 In order to solve the problem of the conventional detection method for recognizing the color shade in a part of the printing surface as a pattern as described above, the upper edge of the calendar page is different for each page in advance. When the bar code pattern display section is printed and the calendar pages for each month are pulled out from the respective paper trays one by one in the order of each page, the sensors arranged in each page sending section are used for the respective calendars. If the pattern of the display unit detected by reading the pattern on the display unit of the page is different from the pattern of the display unit stored in advance, the collator will automatically stop operating or an alarm will be activated. The purpose of the invention is to provide a device for preventing misbehavior that can be emitted.

As a concrete means therefor, the irregularity prevention apparatus according to the invention of claim 1 has a bar code-like pattern display portion which is different for each page in advance in the width direction on the upper edge of a plurality of calendar pages. Each of the collating machines that prints along the line and pulls out the calendar pages for each month one by one in order from the paper tray on which the stacked calendar pages for each month are placed. A sensor for reading the barcode pattern display section is arranged in the page sending section, and a specific pattern display section detected by the sensor of each page sending section is stored in advance in the detection processing device, and each page sending is performed. When the pattern display section of the calendar page that is pulled out to the sensor and detected by the sensor is different from the pattern display section of the page sending section that is stored in advance in the processing device, an alarm is generated or a warning is generated. The feature is that the operation of the machine is stopped.

In this case, the bar code-shaped pattern display portion printed on the upper edges of the plurality of calendar pages has a width that is hidden inside the binding device that binds the upper edges of the calendar pages. It is preferable that the length of the printed pattern is approximately the same as the upper edge of the page so that the sensor can freely and accurately detect any part of the pattern display section.

BEST MODE FOR CARRYING OUT THE INVENTION

 A description will be given of an apparatus for preventing misalignment of a calendar collator according to the present invention with reference to the illustrated embodiment. FIG. 1 is a schematic side view of a collator equipped with a means for preventing irregularities. A plurality of stages of paper trays 2 on which the stacks 3 of calendar pages 4 for each month are placed are arranged. In front of each of these paper trays 2, one surface of the stack 3 on the paper trays 2 is placed. Each of them is provided with a page feeding section 5 for feeding only the calendar page 4 of the above.

Sensors 6 are respectively arranged above the respective page sending-out units 5, and the pasers of the display unit 7 displayed on the respective calendar pages 4 sent from the rear paper receiving tray 2 are arranged. Identify the turn.

As shown in FIG. 2, the display unit 7 displayed on the calendar page 4 has a non-conspicuous portion such as an upper edge of the page in advance when printing a calendar and a landscape image on the calendar page 4. It is printed as a specific pattern determined for each page 4.

As shown in FIG. 3, for example, the pattern display unit 7 is composed of a large number of patterns formed by array arrangement of a plurality of black lines having different thicknesses and displayed at intervals. From among the above, the pattern display portions 7 of the respective specific arrangements corresponding to the calendar pages 4 of each month from January to December are selected, and these pattern display portions 7 are the upper edge 4a of each calendar page 4. It is printed on.

It should be noted that the pattern display section 7 is provided over substantially the entire length along the length direction of the upper edge 4a of each calendar page 4, and the width W of these pattern display sections 7 is set. After the collating work is finished, it is bound inside the binding tool 8 attached to the upper edge 4a of the calendar page 4, and has a size that cannot be discriminated from the outside.

The respective sensors 6 arranged in the page feeding section 5 of each stage are connected to a processing device 9. The processor 9 includes the same number of switches 11 as the page feed section 5 of each stage, and the same number of monitor lamps 12, reset switches 13, memory switches 14 and alarm buzzers 15 corresponding to the switches 11 and the like. There is provided a display panel 10 provided with.

Prior to starting the collation work, the processing device 9 arranges the calendar pages 4 in the correct order in the page feeding section 5 of each stage, and turns on the memory switch 14 of the display board 10 from now on. The correct pattern of the display portion 7 of the calendar page 4 to be combined is stored in the processing device 9.

In this state, when each stage switch 11 of the display board 10 is turned on and the collation work is started, the respective sensors 6 arranged in the page feeding section 5 of each stage are fed from the rear paper tray 2. The pattern of the display unit 7 of each page 4 that has been read is detected, and the pattern is compared with the pattern of the display unit 7 of each page 4 that has been stored in advance. Continue to operate.

When the sensor 6 on any stage detects an abnormality in the process of collating work, the monitor lamp 12 on the stage corresponding to this sensor lights up, the alarm buzzer 15 gives an alarm, and the page feed of any stage is started. The calendar page 4 sent to the section 5 is informed whether it is abnormal. Therefore, the collating machine is temporarily stopped manually or automatically, and the calendar page 4 of the corresponding page sending section 5 is set to the correct page. If there is a misplaced calendar page in the stack of paper trays 2 or not, remove the cause of misalignment, and then turn on the reset switch 13 of the display board 10 to turn it on. Restart work.

[Effect of the invention]

 According to the apparatus for preventing misalignment of the calendar collating machine according to the present invention, the bar code-shaped pattern display portion 7 which is different for each page is printed in advance on the upper edge of the calendar page 4. When the calendar pages 4 for each month are pulled out one by one from 2 in each page order, the sensor 6 arranged in each page sending section 5 reads and detects the pattern of the display section 7 of each calendar page 4. If the pattern of the display unit 7 is different from the pattern of the display unit 7 stored in advance, the abnormality of the corresponding page sending unit 5 is notified and the operation of the collating machine is automatically stopped. Even if there is erroneous stacking in the stacked bundle placed on the table 2, it is possible to reliably prevent misprints due to incorrect pages erroneously stacked at the collation stage.

In addition, in this irregularity prevention device, the sensor 6 arranged in each page sending-out section 5 has a barcode-like display section 7 which is printed in advance on the upper edge of the calendar page 4 and which is different for each page. Since a clear identification pattern is detected, it can be recognized as a different pattern just by slightly shifting or misaligning the target print area, as in the conventional detection method that recognizes light and darkness and shades of color as patterns. It is possible to solve the problem that the collating machine is frequently stopped due to a malfunction, and it is possible to properly exhibit the function of preventing misalignment by the calendar collating machine.

Further, since the calendar page 4 used in the irregularity prevention device of the present invention displays the bar code-shaped display portion 7 which is different for each page on the upper edge over substantially the entire length of the upper edge, the sensor 6 is collated. The sensor 6 can accurately detect the pattern of the corresponding display portion 7 of the calendar page 4 regardless of which portion is provided in each page sending-out portion 5, and the occurrence rate of malfunction can be suppressed. Since the width W of the barcode-like display portion 7 is small, the barcode-like display portion 7 can be finally completely shielded by the binding tool 8, which impairs the commercial value of the calendar. Have no effect such as never.
