DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for inspecting a page of a calendar collator, and more particularly, to a method of inspecting a page collator produced in a collating process when a calendar is manufactured. The present invention relates to a method and an apparatus for inspecting an incorrect page.

[0002]

2. Description of the Related Art Generally, a collating machine is used for producing a calendar. In this calendar collating machine, a unit calendar corresponding to each cover page or a page from January to December, or a sheet on which a plurality of unit calendars are imposed, is stacked on a stacking unit of a collating shelf in a united number. Is to be accommodated.

[0003] When a calendar is manufactured, each unit calendar or a sheet on which a plurality of unit calendars are imposed are sequentially carried out from the stacking unit of the collating shelf of the collating machine in the order of binding and transported. Collating work is performed, and thereafter, binding work to combine them is performed.

[0004] In the calendar as a product, since the product can be added only when the cover and a unit calendar for each month following the cover or a sheet on which a plurality of unit calendars are imposed are bound in a correct order, there is an error in the collating operation. It is very important that this does not happen.

However, since the work of loading each unit calendar or a sheet on which a plurality of unit calendars are imposed on the loading section of the corresponding collation shelf is performed manually by an operator, for example, the loading for one month is performed. A human error may occur, such as adding a unit calendar for February or a sheet with a plurality of imposed multiple unit calendars. For this reason, inconsistent inspection for inspecting collation disorder has been conventionally performed.

[0006] In the conventional random inspection, an optical densitometer (photoelectric conversion element) is installed at a predetermined position of each loading section, and a density difference of a pattern in a specific printing area is read by the densitometer, and the difference is input in advance. There is known a technique for detecting incorrect stacking at the stage of stacking work by detecting erroneous stacking by comparing with a reference density difference pattern.

Further, in Utility Model Registration No. 3033004, a unique pattern display portion different for each page is printed in advance on the upper edge of a calendar page corresponding to a unit calendar, and the display portions are respectively placed on a paper receiving tray ( A technique has been proposed in which a pattern is read by a sensor arranged at a delivery section of a stacking section, and the pattern is read with a reference pattern to detect erroneous stacking.

[0008]

However, in the technique for detecting the pattern density difference, a unit calendar having a similar pattern in a specific printing area or a sheet on which a plurality of unit calendars are imposed exists on a plurality of pages. If so, there is a possibility that false detection of incorrect pages may occur.

Further, the technology proposed in the utility model registration includes a method in which information recorded in a unique pattern display section indicates a month of a unit calendar or a sheet on which a plurality of unit calendars are imposed. Since it is only the month data to represent,
In the same month, there is a problem that even if a unit calendar of a different item or a sheet on which a plurality of unit calendars are imposed is mixed, it cannot be detected.

Further, in these two prior arts, a sensor (including a densitometer) for detecting an erroneous stacking of a unit calendar or a sheet having a plurality of unit calendars imposed thereon must be provided for each stacking unit. In addition, there is a problem that the number of sensors required for the loading unit is several.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is intended for a case where a unit calendar for a plurality of pages having a similar pattern in a specific printing area or a sheet on which a plurality of unit calendars are imposed exists. Provided is a method and apparatus for inspecting a page of a calendar collator that can reliably detect a page with a single sensor even when a unit calendar of different months or a sheet on which a plurality of unit calendars are imposed is mixed. The task is to

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view conceptually showing a page inspection apparatus for a calendar collator according to a first embodiment of the present invention.

The random inspection apparatus according to the present embodiment includes a plurality of stacking units 1 each of which stacks a unit number of unit calendars constituting a cover of a calendar or pages from January to December.
And a collating machine 14 having two collating shelves 12 each consisting of zeros and a predetermined position of each unit calendar in order to detect a misaligned page in the collating process of sequentially carrying out and transporting each unit calendar from the corresponding loading unit 10. Barcode reader (sensor) 16 that reads a barcode (to be described in detail later) printed on the printer, and a thickness detection sensor 1 that detects the thickness of the unit calendar being conveyed.
8 is provided.

In the collating machine 14, the unit calendars loaded on the loading section 10 of each collating shelf 12 are arranged in the direction indicated by a plurality of horizontal arrows in the drawing in the order of binding the calendars as products. When sequentially conveyed, while being conveyed in a downward arrow direction while being sandwiched by a belt (not shown) while maintaining the order, after passing through the conveying section 20 to the left and further passing through the slope conveying section 22, Only conforming non-defective products are accumulated in the stack section 24.

In this embodiment, the bar code reader 1
6 is installed above the common transport unit 20A through which all the unit calendars unloaded from each loading unit 10 pass, and the barcode can be read from the unit calendar being transported, and the read data is detected. Computer 2 as a means
When the data is input to the computer 6, the computer 26 carries out a later-described inspection of incorrect pages.

The thickness detecting sensor 18 is provided at an upper end position of the slope conveying portion 22 and detects the thickness of a unit calendar (which overlaps in a to-be-described manner) passing thereunder, and detects the thickness. By outputting the data to the computer 26 in the same manner, the computer 26 performs an incorrect inspection.

In the present embodiment, as described above, the unit calendars constituting each page of the product calendar are loaded on the stacking unit 10 of the collating shelf 12 of the collating machine 14 in a united number. However, as shown conceptually in the perspective view of FIG. 2, each of these unit calendars U has, at the upper end thereof, item data as a calendar and page data representing the page number of the calendar. The barcode B is printed with data such as month data indicating the month of the month, and the number of collated sheets indicating the total number of calendars.

The bar code B is printed at a position where a predetermined number of unit calendars are attached to the metal fittings Ca as shown in FIG.
When the binding is performed, a binding margin hidden by the metal fitting Ca is hit, and a position where data can be read by the barcode reader 16 at the front end in the conveyance direction at the time of collation.

As will be described later, the collating machine 14 of the present embodiment has a function of collating a predetermined number of unit calendars into a so-called scissor shape.

Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

When collating to produce a calendar for a certain item, the operator checks whether all the items of the unit calendar to be loaded on each loading section 10 match or not (step 1). After confirming that,
Each loading operation of manually loading the corresponding loading section 10 is performed (step 2).

Thereafter, the operation of the collating machine 14 is started (step 3), and at the same time, data is read from the barcode B of the unit calendar U being conveyed by the barcode reader 16 (step 4), and the data is transferred to the computer. 26, the data is collated with data that has been input in advance (step 5), and a page inspection according to the present embodiment is performed.

As a result of collating the data for the unit calendars for the number of sheets to be collated, if the collation is correct (OK in step 5), the flow returns to step 3 to perform collation for the next calendar. Conversely, if the occurrence of a page misalignment is detected in step 5 (NG in step 5), the apparatus is stopped or rejection for removing a defective collated product is performed (step 6). Return and do the next collation.

FIG. 5 is a perspective view conceptually showing a state of data reading (reading) in step 3 described above. However, the unit calendar U that does not actually cover the bar code B
The transporting belt sandwiching the position (1) is omitted.

FIG. 5 shows the bar code reader 16.
And a predetermined number of unit calendars U being conveyed, each unit calendar U has a bar code B printed at the front end in the conveyance direction, and only the vicinity thereof is exposed. On the rear side in the transport direction, the next unit calendar U is transported in a state where the next unit calendar U is overlaid, that is, in a so-called scissor shape. And during transportation in this state,
All unit calendars U by the barcode reader 16
Are sequentially read.

In the present embodiment, as described above,
Since the barcode reader 16 is installed at an upper barcode readable position close to the common transport section 20A through which all the unit calendars U pass, the barcode reader 16 can read the barcodes of all the unit calendars U. Since it is possible, the inspection of the incorrect page can be surely performed by one sensor. Therefore, there is an advantage that the apparatus can be simplified and manufactured at a low cost as compared with a conventional incorrect inspection apparatus which requires sensors for several loading sections (paper receiving sections).

In the present embodiment, the bar code B is read while the unit calendar U is conveyed in a pinching manner by the bar code reader 16, so that it is possible to carry out the collation work and the inspection for incorrect pages in a short time. it can.

Since the bar code B printed on each unit calendar U records item data, page data, and the number of collated sheets, for example, the unit calendar of the wrong item is mixed, and So-called missing pages, such as missing second page of the 14-page bound calendar, or bar code B
Is not read, it is possible to detect various irregularities such as the direction of the unit calendar U being reversed.

Further, depending on the bar code reader 16, two or more unit calendars U of the same page are overlapped.
So-called extras cannot be detected, but according to this embodiment,
The thickness detection sensor 18 can detect the total thickness of the unit calendars conveyed in a state of being overlapped in a pinching state, so that even if additional pages occur, it is possible to detect the total number of pages reliably. Inspection can be performed.

Next, a second embodiment according to the present invention will be described. The present embodiment is substantially the same as the first embodiment except that the sheet on which a plurality of unit calendars shown in FIG. 6 are imposed is used instead of the unit calendar shown in FIG. Is the same as

The sheet shown in FIG. 6 has four unit calendars U of January imprinted thereon, and a bar code B is similarly printed on the upper portion corresponding to the front end in the transport direction. The bar code B is printed at the cutting margin of the sheet, and is finally cut and removed when the sheet is divided into four parts to create a product calendar.

Although the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist thereof.

For example, in the above-described embodiment, the case where the unit calendars are transported in a pinching manner is shown. However, the present invention is not limited to this.

Although the case where the barcode B is printed at the binding margin of the unit calendar U has been described, it may be printed at the trimming margin which is finally cut.

Although the barcode has been described as recording item data, page data, and collation data, the present invention is not limited to this, and other data may be recorded. Good.

[0040]

As described above, according to the present invention,
Even if there is a unit calendar for multiple pages with similar patterns in the specific printing area or paper with multiple unit calendars imposed, mixed paper with unit calendars or multiple unit calendars for the same month with different items mixed In this case, it is possible to reliably detect the incorrect page with one sensor.
