Description

  The present invention relates to processing of waste paper such as banknotes, stock certificates, gift certificates, postal tickets, and valuable printed matter such as securities.

  Usually, valuable printed matter such as banknotes, stock certificates, gift certificates, postal tickets, securities, etc., must meet any quality standards required for the product in the quality inspection in the manufacturing process. If a defect occurs due to mechanical or human causes and does not meet the quality standards, it is treated as waste paper (which cannot be distributed as a product).

  Also, usually in the printing industry, paper used for machine adjustment in the manufacturing process, paper used for adjusting the color of printing before the final printing in the printing process (adjustment paper), and processing process Paper used for trial processing before this processing is also handled as waste paper.

Here, these waste papers are roughly classified into the following two types.
Defective paper: Paper that has an abnormal shape, such as torn, broken, perforated, attached to tape, or adhered foreign matter. (In some cases, once the substrate shape is broken, the shape is restored. Including)
Stained paper: Paper that does not have an irregular shape, such as printing mistakes, ink stains, poor ink transfer, poor density, and poor color tone.

  These spoiled papers, even spoiled papers, need to be disposed of after a strict quantity check (in the description, “quantity check” means checking the number of spoiled paper). Yes, there should be no mixing of waste paper into the product (good paper), loss of lost paper, or outflow. Therefore, conventionally, disposal is performed after counting the end face of the waste paper and the corner of the waste paper and guaranteeing the quantity.

  On the other hand, in order to detect the defaced state of banknotes etc. that are distributed in the market, the pass / fail judgment is made according to the established criteria, the passable ones are circulated again, and the rejected ones are counted and discarded. There is something to do. (Patent Document 1)

Patent 3540526 (page 13, Fig. 1)

  However, even if the amount of waste paper can be confirmed simply by counting and disposing of the waste paper edge and corners, holes other than the edge and corner of the waste paper (for example, the center of the surface of the waste paper) will be perforated or torn. In such cases, it is not possible to check whether or not there are all the pieces of paper that make up the paper substrate. Therefore, it is critical in the manufacturing process that abnormal paper pieces are mixed, lost, or leaked into the product (good paper). Could cause serious problems. Therefore, in the waste paper processing, it is necessary to perform shape confirmation (in the specification, “shape confirmation” means confirming whether there is an abnormality in the base material shape of the paper) as well as quantity confirmation. To do that, I had to rely on visual inspection.

  By the way, as described above, the waste paper is divided into a dirty paper and a defective paper, and the defective paper has an abnormality in the shape of the base material, so it is necessary to confirm the shape along with the quantity confirmation. Since there is no abnormality in the shape of the material, it is only necessary to perform processing that cannot be restored to the original state, such as crushing, cutting, shredder, incineration, and steaming, after quantity control. .

  However, because waste paper may be a mixture of missing paper and soiled paper, it is necessary to visually check the shape of all the waste paper. Needed. In addition, in the inspection process, etc., a lot of work such as transporting and transshipping paper is required, and there is a problem that the risk of loss of mixed paper, loss of lost paper, loss of damaged paper, etc. increases. It was.

  Furthermore, in human visual inspections, oversight and variations in judgment criteria occur, and even slight perforations or corner breaks in the paper substrate may not be detected, which may cause serious problems in the manufacturing process. .

  On the other hand, there has been one that determines pass / fail in order to recycle banknotes in circulation as in Patent Document 1, but there has been no one that is intended to process waste paper.

  Therefore, the present invention was made in view of the problems of the prior art, and the waste paper generated in the manufacturing process of the valuable printed matter is a missing paper that requires pursuing causes such as human visual inspection and history confirmation, By mechanically separating the paper into dirty paper that can be disposed of without the need for human visual inspection or history confirmation, the waste paper can be mixed into the product without spending time and cost.

However, the present invention is not limited to the best mode for carrying out the invention described below, and includes various other embodiments within the scope of the technical idea described in the scope of claims.

  FIG. 1 is a block diagram showing the configuration of the waste paper processing apparatus of the present invention.

  The waste paper processing apparatus includes a supply means for supplying waste paper, a transport means for transporting the waste paper, an inspection means for inspecting whether the transported waste paper is defective paper or dirty paper, The apparatus comprises a missing paper discharge means for discharging the defective paper determined by the inspection means, and a dirty paper discharge means for discharging the dirty paper determined by the inspection means.

  In addition, a waste paper processing apparatus according to the present invention is configured by including a disposal means in the waste paper processing apparatus.

  In addition, the waste paper processing apparatus according to the present invention includes a counting means or a weighing means.

  FIG. 2 is a schematic view of a waste paper processing apparatus according to the present invention.

  As shown in FIG. 2, the waste paper processing apparatus 1 is provided with a supply means 2 (not shown in detail) for taking out the stacked waste paper 7 one by one from the upper surface side. The waste paper 7 is supplied to the conveying means 3 one by one.

  As the supply means 2, a soccer method (a back-up method using a single suction or a double suction, a feeder of a front-end method using a single suction), a roller (a method adopted in a copying machine or a commercially available printer), or the like is used. Any form may be used as long as it is possible to take out the waste paper one by one from the top side. Further, the supply means is not limited to the sheet-fed feeder as shown in the figure, and can be used also with a feeder that supplies a continuous printed matter using a web.

  What is supplied by the supply means is damaged paper caused by man-made or mechanical causes in the manufacturing process, or paper (adjustment paper) used for machine adjustment in the manufacturing process or color adjustment in printing, etc. is there. As shown in FIG. 3 (a), the size of the waste paper may be a single-sided sheet having a plurality of one-sided slices, or may be a piece of paper such as a banknote or a gift certificate. Any size can be processed without restriction.

  The waste paper 6 taken out by the supply unit 2 in FIG. 2 is sequentially sent to a conveyance path 3 serving as a conveyance unit, and is conveyed along the conveyance path at a constant speed. The transport path 3 may have any form as long as it can transport the waste paper such as belt transport, roller transport, and gripper transport.

  The inspection unit 4 is provided in the middle of the conveyance path 3, and the inspection unit 4 includes a detection unit and a determination unit (both not shown). In the detection unit, one or more detectors are arranged right above the conveyance path 3 at the most suitable angle so that the detection unit can detect the state of the entire side of the waste paper conveyed at a constant speed. It has become. Then, the detection result detected by the detection unit is used to determine whether or not there is a loss in the waste paper in the determination unit.

  FIG. 3 shows the state of supplied waste paper.

  As described above, the waste paper is roughly divided into a dirty paper having no defect in the base material shape itself as shown in FIG. 3B, (c) perforated, (d) bent, and (e) torn. , (F) wrinkles, (g) there are two types of missing papers that are once torn or perforated in the paper and have defects in the substrate shape itself as shown in the paper repaired with tape, etc. In many cases, missing paper is mixed.

  Here, a case where a CCD camera is used as a detector for discriminating between the dirty paper 8 and the missing paper 9 will be described. As shown in FIG. 4, the required number of CCD cameras as detectors are arranged above the damaged paper so that the entire damaged paper is within the detection range. When the waste paper conveyed from the conveyance path to the inspection means is the dirty paper 8 as shown in FIG. 3B, the waste paper image is captured by the CCD camera and binarization processing (light / dark) is performed. When the process of converting the image into a binary image is performed, the state shown in FIG. 4B is obtained, and the missing portion is not confirmed. On the other hand, if the damaged paper conveyed to the inspection means from the conveying path is a defective paper 9 as shown in FIG. 3C, the damaged paper image is captured by the CCD camera and binarization processing is performed. If it does, it will be in the state shown in FIG.4 (c), and since the defect | deletion site | part (perforation) is confirmed, it will be discriminate | determined from the missing paper 9 in a discrimination | determination part.

  As described above, the defective paper and the dirty paper can be discriminated because the reflectivity of the paper and the captured image are different between the perforated portion 12 and other portions in FIG. This is because the perforation 12 can be made apparent by performing image processing based on density. In addition, in the state of FIG. 4B, the number of perforated pixels after binarization is 0, whereas in the state of FIG. 4C, the number of perforated pixels is 0 or more. By setting the threshold value of the number of pixels to an arbitrary range of 0 or more, the size of the defect can be selected.

Next, a case where a regression laser sensor is used as a detector for selecting the dirty paper 8 and the missing paper 9 will be described.
FIG. 5 shows a system for discriminating between dirty paper 8 and missing paper 9 using a regression laser sensor. The regressive laser sensor is a sensor that uses a special reflector 21, and includes a regressive light projecting sensor 19 and a recursive light receiving sensor 20. When the regressive laser sensor is used, the laser light is irradiated from the regressive light projection sensor 19 and the light reflected by the special reflector 21 is detected by the regressive light receiving sensor 20, but the other light is It is not detected by the regression type light receiving sensor 20. Therefore, as shown in FIG. 5, the return type laser sensor is disposed above the damaged paper, and the damaged paper conveyed to the inspection means from the conveying path is the dirty paper 8 as shown in FIG. In some cases, even if laser light is irradiated by the regressive projection sensor, the reflected light from the special reflecting plate 21 is not detected, so that no waveform appears (FIG. 5B). However, when the waste paper conveyed from the conveyance path to the inspection means is, for example, missing paper 9 (perforated) as shown in FIG. Since the light from the plate is detected, the missing paper can be detected (FIG. 5C), and thereby, the dirty paper 8 and the defective paper 9 can be discriminated.

  When a regressive laser sensor is used, only the reflected light of the special reflector 21 is detected from a perforated or torn part, so that an optical change element (hologram or optical change ink) is applied to the surface of the waste paper. Can be selected without being affected by the optical change element on the surface.

  In addition, what is necessary is just to arrange | position suitably according to a test object and the detection range to obtain | require about the kind, installation conditions, etc. of a regression type laser sensor. For example, when a LV-H65 type made by Keyence Corporation is installed as a regression laser sensor in a location 20 to 30 cm away from the surface of the damaged paper, and the laser beam is irradiated to the damaged paper, the target is detected in the range of 15 mm to 17 mm. Can do. When the paper conveyance speed is about 120 sheets per minute (corresponding to 60 m / min), it is possible to detect a defect portion of a square with a side of 5 mm or more.

  Next, a case where an ultrasonic sensor is used as a detector will be described. FIG. 6 shows a method of detecting the dirty paper 8 and the missing paper 9 using an ultrasonic sensor. When the ultrasonic sensor is used, a strong or weak waveform is shown depending on the thickness of the damaged paper to be inspected. Therefore, the dirty paper 8 and the missing paper 9 can be selected by providing an arbitrary threshold value for the waveform. . That is, as shown in FIG. 6, the required number of transmission sensors 22 of the ultrasonic sensor are arranged above the waste paper, and the waste paper conveyed to the inspection means from the conveyance path is as shown in FIG. In the case of the dirty paper 8, the ultrasonic reception signal received by the reception sensor 23 shows a normal level waveform as shown in FIG. However, when the waste paper conveyed to the inspection means from the conveyance path is, for example, a defective paper (perforated 12) as shown in FIG. 3C, the ultrasonic reception signal of the defective portion of the perforated 12 is Since the waveform is higher than the normal level as shown in FIG. 6C, it can be seen that there is a missing portion on the waste paper. In addition, in the case of the waste paper to which foreign matters such as tape adhere as shown in FIG. 3 (g), the waveform is lower than the waveform at the normal level as shown in FIG. 6 (g). It turns out that it is the missing paper 9 with abnormality, such as a kimono.

  As the ultrasonic sensor, various types such as Nireco PC-200 and PC-300 used for the two-sheet-feeding sheet detection device can be used. When the ultrasonic sensor is used, the detection accuracy is high because it is not affected by the pattern or the like of the waste paper to be detected.

  Similar to the ultrasonic sensor described above, a contact sensor can be used as a detector to detect irregularities on the paper surface by contact. As shown in FIG. 7, when the contact type sensor 24 is used to detect FIG. 3 (b), a normal level waveform is detected, but a missing paper as shown in FIGS. 3 (c) and 3 (g) is detected. Then, as shown in FIGS. 7C and 7G, since the waveform at the normal level is not detected, it is possible to determine the missing sheet by providing a threshold value.

  As described above, the detector for selecting the dirty paper and the missing paper can be appropriately selected according to the size of the damaged paper and the state of the damaged paper. For example, by using an ultrasonic sensor alone as a detector and setting each threshold value, it is possible to detect both perforations and tape adhering with different properties in the missing paper, and the sensor response. An ultrasonic sensor and a regression laser sensor may be used in combination in order to eliminate a speed problem and a defect when perforation or tape adhesion occurs at the same timing.

  The determination result of the presence / absence of a defect in the determination unit is transmitted to a control unit (not shown), and whether the control unit discharges the paper as dirty paper to the dirty paper discharge unit 5 or whether to discharge the defective paper to the defective paper discharge unit 6 , Either switching is performed. What is determined not to be defective by the inspection means 4 is discharged to the dirty paper discharge means 5 along the first direction (arrow 1 in FIG. 2) as the dirty paper 8 by the switching. What is determined to be present is discharged as missing paper 9 to the missing paper discharge means 6 along the second direction (arrow 2 in FIG. 2). With this configuration, it is possible to reduce the classification work because it is less time-consuming than sorting the missing paper and the dirty paper by marking, etc., and manually discharging the paper discharged to the same discharge means. .

  The dirty paper 8 discharged to the dirty paper discharge means 5 and the defective paper 9 discharged along the defective paper discharge means 6 may be sequentially stacked on a stacking table or the like. Instead of being stacked, it may be transported to a subsequent process in the same form as the transport path 3 described above.

  The missing paper 9 discharged along the missing paper discharge means 6 is subjected to confirmation work such as confirmation of a defective state and tracking of a manufacturing process history by an operator or the like.

  FIG. 8 is a block diagram of a waste paper processing apparatus provided with disposal means according to the present invention (corresponding to claim 2). As shown in FIG. 8, the disposal means 25 is installed downstream of the dirty paper discharge means 5, and may be configured to sequentially dispose of the discharged dirty paper every time it is discharged, as shown in FIG. As described above, after the waste paper discharge means 5 discharges, the stacked dirty paper may be collectively disposed of by the disposal means 27.

  As a disposal means, a general shredder mechanism with a rotary blade, a crushing mechanism for crushing, a slitter, a guillotine cutting, a rotary cutter, a chop cut, a simmering device, etc. can be used. By using the paper processing apparatus including the disposal unit 25, it is possible to further eliminate the risk of loss, outflow, dissipation, and the like of the dirty paper. In particular, the configuration shown in FIG. 8 can omit the step of transporting the laminated dirty paper to the disposal means, as compared with the configuration shown in FIG. 9, and thus not only helps to prevent the loss, outflow, dissipation, etc. of the dirty paper. , Which also helps reduce labor costs.

  The waste paper processing apparatus of the present invention can be provided with a counting (amount) means for performing the paper loss processing more reliably. (Corresponding to Claim 3) The counting (amount) means is installed in, for example, the supply means 2, the dirty paper discharge means 5 and the missing paper discharge means 6, respectively. Note that a counting (amount) means may be installed in the transport path 3 and the inspection means 4 as necessary. Each counting (amount) means may be provided so as to count (amount) the waste paper that passes through the conveyance, or after being discharged from the dirty paper discharge means 5 and the missing paper discharge means 6, respectively. You may provide so that the dirty paper 8 and the missing paper 9 of the state which were made may be counted (amount).

  As the counting means, it is possible to use a counting counter that performs non-contact counting by an optical sensor system, a wiper blade type contact type counting machine that applies a blade that sings one by one with vacuum suction, It is not limited to these. For paper with high specific gravity and paper that is not easily affected by moisture, weigh not the number of sheets but the weight of the paper processing device supply means and the weight of the discharged dirty paper or missing paper. A device 27 can also be provided (FIG. 9).

  Further, in the case of a waste paper processing apparatus provided with a disposal means, a counting device is installed in one or more of the supply means 2, the conveyance path 3, and the inspection means 4, and the dirty paper discharge means 5 and the missing paper discharge It is also possible to adopt a configuration in which a counting (quantity) device is installed in each of the means 6 or the disposal means 25 (Claim 4).

  If the supplied number of lost paper or lost paper weight does not match the number of lost paper or the lost paper weight obtained by adding the dirty paper 8 and the missing paper 9, a display or warning for notifying abnormality is issued. Can inform the abnormality. By adopting such a configuration, quantity management in the waste paper processing apparatus can be performed more reliably, and security is improved.

  In order to further improve security, the waste paper processing apparatus of the present invention is provided with a bundling means, and the waste paper 8 discharged and stacked, for example, as shown in the bound paper 28 shown in FIG. It may be configured to be cross-bundled or well-shaped by PP band or paper band for every set quantity by a bundling device or the like, or may be configured to be sealed by paper or plastic bag . By adopting such a configuration, it can be used for prevention of dissipation in the case of disposal of paper at another place.

  Note that the waste paper processing apparatus of the present invention can be provided in a printing press. With such a configuration, partial paper breaks or breaks caused by loading paper during the printing process or inserting wedges used to adjust the height of the loaded paper, etc. Can also be detected. Furthermore, a cylinder printing caused by partial tearing or folding of the paper (when the paper is not supplied or the supplied paper is torn or broken, etc., the cylinder surface or the rubber cylinder is in contact with the impression cylinder) This means that the ink on the plate surface or rubber cylinder is transferred directly to the impression cylinder instead of paper.) It is also possible to detect the paper to be printed.

  It is also possible to provide the inspection means of the present invention between the paper supply unit of the printing press and the actual printing unit. With this configuration, it is possible to detect adhesion of foreign matter (plastic, metal pieces, or tape) to the paper immediately before entering printing, preventing damage to the printing plate or blanket due to foreign matter during printing. can do.

  Next, the waste paper processing method according to the present invention will be described with reference to the flowchart shown in FIG.

  That is, in the waste paper processing method according to the present invention, first, the stacked waste paper is sequentially supplied to the transport path one by one from the upper side (step S1), and the waste paper is transported at a constant speed (step S1). S2) The transported waste paper is inspected to determine whether the waste paper is missing or attached with foreign matter (step S3). In this inspection, if there is no defect or foreign matter adhesion on the damaged paper, it is determined that it is dirty paper (step S4), and is discharged in the direction of dirty paper discharge (step S5). If there is, it is determined that the paper is missing (step S6), and the paper is discharged in the missing paper discharge direction (step S7).

  The paper processing method according to the present invention may be provided with a step of disposing the discharged dirty paper 8 so that the original form is not known after step S7.

  In addition, the waste paper processing method according to the present invention may include a counting (quantity) step in order to more reliably perform the waste paper processing. The counting (quantity) process can be performed in a process before and after step S1, a process before and after step S2, and a subsequent process in step S5 and step S7. Most preferably, the quantity of waste paper supplied before step S1 is determined. Count, count the number of damaged paper after step S5, count the number of missing paper after step S7, and confirm that the quantity of supplied waste paper is equal to the total number of discharged waste paper and missing paper Good. By further adding such a method to the waste paper processing method, the quantity management can be strictly performed and the security can be further improved.
