Description

  The present invention relates to a paper sheet processing apparatus for discriminating paper sheets, and more particularly to a paper sheet processing apparatus used for discriminating paper sheets with poor finish after manufacturing.

  Conventionally, when a defective determination paper is generated, the cause of the defect determination is specified by first visually confirming the removed paper itself.

  However, if the defective judgment paper remains for a long period of time, there is a risk of mixing into the normal judgment paper group, and therefore it has been necessary to dispose of it promptly in terms of security.

  On the other hand, if the failure determination paper is disposed immediately, the cause of the failure occurrence by visual inspection is neglected, and improvement feedback to the failure occurrence source is delayed, and as a result, the reduction of the failure occurrence rate does not progress.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a paper sheet processing apparatus that can sufficiently analyze the cause of occurrence of a failure and can immediately dispose of a failure determination sheet.

The paper sheet processing apparatus of the present invention is a paper sheet processing apparatus that discriminates normal or bad paper sheets while conveying a medium to be processed including paper sheets,
A detection unit that detects a feature amount of the paper sheet; a determination unit that determines whether the paper sheet is normal or defective based on a result of the detection unit; and an image reading unit that reads an image of the paper sheet Inspection equipment,
A cutting unit that cuts a paper sheet determined to be defective based on the determination result of the determination unit;
A stacking unit that stacks paper sheets determined to be normal based on the determination result of the determination unit;
A display unit that displays only images of paper sheets determined to be defective based on image information read by the image reading unit;
And an image data storage unit that stores an image of a paper sheet that is determined to be defective and is cut.

  According to the present invention, it is possible to obtain a paper sheet processing apparatus that can sufficiently analyze the cause of occurrence of a defect and that can immediately dispose of a defective determination sheet.

  As shown in the figure, this paper sheet processing apparatus 1 has a paper sheet supply unit 10 for feeding paper sheets to be processed.

  The paper sheet supply unit 10 includes a cassette loading unit, a scraping unit, a reversing unit, and a winding unit (not shown). Using the 5,000-sheet storage cassette A, the predetermined printed paper sheets B in the 1000-sheet stacking state are continuously fed (ST1), scraped out from the cassette A in the 1000-sheet stacking state, and the top and bottom in the stacking direction is reversed. After carrying out further addition (ST2), it automatically conveys to the take-out conveyance device 11. Up to two cassettes can be loaded into the machine at one time, and empty cassettes that have been taken out of paper can be stored in two cassettes.

  At the upper end of the paper sheet supply unit 10, there is provided a take-out conveyance device 11 that takes out the paper sheets C fed into the paper sheet supply unit 10 one by one from the upper end and sends them to the conveyance path. As the take-out conveyance device 11, for example, a suction roller that rotates while being in contact with the uppermost paper sheet and generating a negative pressure can be used. The suction roller is formed, for example, so as to take out one sheet of paper every rotation, and takes out the paper sheet at a predetermined pitch (ST3).

  On the downstream side of the take-out conveyance device 11, a conveyance path 14 that conveys the extracted paper sheet through the processing device 1 is extended. A conveyance belt and a driving pulley (not shown) are disposed on the conveyance path 14, and paper sheets are conveyed along the conveyance path 14 at a constant speed by running the conveyance belt by a drive motor (not shown). .

  On the conveyance path 14, an inspection device 23 that detects the characteristics of the paper sheet being conveyed on the conveyance path 14 is provided.

  The inspection device 23 includes, for example, two image reading devices 6 a and 6 b that are disposed on both sides of the conveyance path 14 and read images on both sides of a paper sheet. The image reading devices 6a and 6b have, for example, a light source, a sensor, and a CCD camera, and can read a pattern on the surface of a paper sheet from a photographed image, and can detect the size and conveyance pitch of the paper sheet. .

  The inspection device 23 is connected to a control unit 101 described later, and the control unit 101 collects image data obtained by the image reading devices 6 a and 6 b and transmits the collected image data to the information processing unit 102. This image data can also be stored in the image data storage unit 111 via the information processing unit 102 (ST6).

  Further, the inspection device 23, as the detection unit 26, for example, inspects the thickness of the conveyed paper sheet and can detect the overlap of the paper sheet, and a counting device that counts the number of paper sheets In addition, a magnetic detection unit for detecting a magnetic component contained in the paper sheet ink is provided.

  The inspection device 23 performs necessary inspection on the conveyed paper sheets and makes a determination by a determination unit (not shown) (ST6). Through this inspection, the type (unit), direction (front / reverse / inverse), normal, and defective of the paper sheet are determined, and the paper sheet is classified into normal determination paper, defective determination paper, and uninspectable paper. (ST7, ST8).

  “Normal determination paper” is a paper sheet determined to be regular and valid as a result of the determination.

  The “defect determination paper” is a paper sheet that has been determined to be invalid because the finish after manufacture is unsatisfactory and distribution is not appropriate. As a cause of poor finishing, for example, a printing mistake, a cutting mistake, and the like can be given.

  Also, “uninspectable paper” refers to, for example, overlapping, skew, that is, paper sheets are skewed, short pitch, that is, the interval between the paper sheets in the transport path is too short and subsequent processing is performed. Paper sheets that could not be correctly inspected for reasons such as difficulty. Here, this is called exclusion paper.

  On the transport path 14, two gates G1 and G2 are sequentially arranged. Each of the gates G1 and G2 is switched according to the control by the control unit 101 based on the detection result in the inspection device 23, and directs the processing target medium to a predetermined processing unit.

  A gate G1 disposed immediately after the inspection apparatus 23 is provided at a position where the conveyance path 14 branches to the exclusion conveyance path 14a, and the sheets determined to be excluded via the inspection apparatus 23 are excluded conveyance path 14a. Is switched to branch to. At the end of the exclusion conveyance path 14a, an exclusion sheet stacking device 19 (exclusion unit) that stacks the exclusion sheet is provided. In the reject paper stacking device 19, for example, a medium having a poor conveyance state, a medium that cannot be determined as paper sheets, and a stack of paper sheets are stacked (ST5).

  The paper sheet C determined to be defective as a result of the inspection is transported to the cutting unit 15b by the gate G2 provided along the transport path 14 on the downstream side of the gate G1, and immediately cut (ST9). Accordingly, the defect determination paper is displayed on the image (ST10). The cause of the failure can be analyzed visually from this display screen.

  In addition, an accumulation sealing unit 15a is provided at the other side of the position branched by the gate G2.

  The stacking and sealing unit 15a is a device that stacks the conveyed paper sheets and performs sealing with a band in units of 100 sheets.

The 100-sheet band hanging unit 52 further includes a band feeding, band loading, band feeding, band cutting, band hanging, and bonding mechanisms. The paper sheets determined to be normal as a result of the inspection are sequentially conveyed and classified into the normal determination paper stacking unit 51, and the continuous 100 sheets taken out by the take-out transport apparatus 11 are stacked (ST11), and 100 sheets of paper sheets are collected. When the is accumulated, the sealing operation starts. The hundred-sheet banding unit 52 performs banding at a predetermined position of 100 sheets of accumulated paper sheets (ST14). When defective determination sheets and rejection sheets are generated in 100 consecutive sheets, it is determined whether or not the number of normal determination sheets is equal to or greater than a predetermined number (ST12). When the number is less than the predetermined number, the operation is stopped, and a process for supplementing the normal judgment paper stacking unit 51 with dummy paper for the number of defective judgment papers and the number of rejected paper sheets is separately performed (ST13). To resume.

  The hundred-sheet bundle moving unit 109 includes a conveyor 81, a lifter 82, a print reading (not shown), and a rotation mechanism. The bundled hundred-sheet bundle D is automatically conveyed by the conveyor 81 and the lifter 82 (ST15), and reading confirmation of the number printed on the uppermost sheet of the hundred-sheet bundle in the middle of conveyance is performed (ST16). Only the bundle is turned upside down in the paper printing direction.

  Thousand-sheet banding section 17 is provided at two locations (17a, 17b), and is composed of banding paper feeding, band loading, band feeding, band cutting, band hanging, rotation and adhesion mechanisms. Ten transported bundles of 10 sheets are collected, banded in the order of the horizontal band (longitudinal direction) and the vertical band (short direction) (ST17), and conveyed to a label affixing section (not shown).

  The label sticking unit 110 includes label issuing, sticking, and discharging devices. Based on the information of the bundled thousand bundles E to be conveyed, predetermined printing is performed on the label, and the label is attached to a predetermined position (ST18). After collecting the bundle, it is discharged out of the apparatus as a bundle of 5,000 sheets F (ST19).

  In addition, paper sheets that are in a poorly transported state or cannot be inspected are transported and collected in the reject paper stacking device 19 by the gate G1.
