Description

  The present invention relates to a system for managing the quality of a bundle of signatures bound by a stacker bundler.

  The signatures discharged from the rotary press pass through the folding machine and are conveyed to the stacker bundler by the signature conveyor. A predetermined number of signatures are collected and bundled in the stacker bundler, and are bound by the binding band.

  The folding machine sorts the folded signatures into sheets one by one with an internal impeller, and the impeller discharges paper onto the conveyor so that the signatures are stacked (for example, Patent Documents). 1-3). The impeller includes a plurality of blades for sorting sheets, and one sheet is carried by one blade. In general, a non-contact sensor such as a transmissive photoelectric switch is disposed in the vicinity of the impeller, and a pulse signal is generated every time the blade of the impeller crosses the transmitted light of the transmissive photoelectric switch. The stacker bundler counts this pulse signal by a counter provided in the stacker bundler, thereby counting the number of signatures conveyed from the rotary press and creating a predetermined number of signature bundles.

  A lot number, a date, and the like are printed on a binding band that binds a bundle of signatures (for example, Patent Document 4).

  Conventionally, inspecting a printing failure or the like of a signature has been performed by extracting a signature from a folding machine from a signature conveyor.

  The signatures can be extracted when the operator randomly selects, or when a signature extraction device (for example, Patent Documents 5 and 6) installed on the signature conveyor receives a count signal from the counter of the stacker bundler, May be extracted. The extracted signature is transferred to an inspection process, and is usually inspected visually.

When a defective printing signature is found by sampling inspection, the binding band of the already bundled signature bundle is removed and checked, and the rotary press is inspected and repaired for improvement.
JP-A-2005-41600 JP 2004-352479 A JP 2002-104703 A JP 2003-146306 A Japanese Patent Laid-Open No. 10-305942 JP 2006-199468 A

  However, the sampling inspection is basically a visual inspection, and an inspection omission may occur in the case of a slight printing defect or the like. When inspection failure occurs and a printing defect is found at the delivery destination, all bundles at the delivery destination must be inspected, and there is a problem that the inspection work takes an enormous amount of time.

  Therefore, the present invention provides a signature quality management system that can shorten the time required for inspection work and improve quality control by enabling identification of a bundle including defective signatures. .

  The signature management system according to the present invention receives a signature that is conveyed by the conveyor, a conveyor that conveys the signature group, a counter that counts the number of signature groups conveyed on the conveyor, A bundle creating unit that accumulates a predetermined number of signatures based on a count signal of the counter to create a signature bundle, a binding unit that binds the signature bundle with a binding band, and a counter installed on the conveyor. A signature extracting device for extracting a signature for each bundle of signature bundles to be accumulated from the row of signatures conveyed on the conveyor, and the signature extracting device. Each signature should be bound to a first marking device for marking first identification information that can identify each signature, and a binding band that binds each of the signature bundles from which the signature has been extracted. Signature bundle A second marking device for marking the second identification information may identify the associated that is marked withdrawn signatures the first identification information and Kakuorihinototaba, characterized by having a.

  The first marking device marks first identification information including a numerical value sequentially incremented for each signature extracted by the signature extraction device, and the second marking device belongs to the extracted signature. It is preferable that the binding band of the signature bundle is configured to mark the second identification information including the same count-up value as the count-up value marked on the extracted signature.

  The first marking device and the second marking device are a bundle of a bundle of signatures to which the first signature is marked by the common control device and the first identification information marked on the extracted signature. You may make it control so that common identification information may be included in the 2nd identification information marked on a band.

  According to the signature quality control system according to the present invention, the first identification information marked on the extracted signature and the second band marked on the binding band of the signature bundle to which the extracted signature should belong. By associating with the identification information, the first identification information of the extracted signature and the second identification information of the binding band of the signature bundle are collated to identify the signature bundle that should contain the extracted signature. As a result, it is not necessary to inspect all products as before.

  A best mode for carrying out a signature quality control system according to the present invention will be described below with reference to FIGS.

  FIG. 1 is a side view showing the overall configuration of a group of devices constituting a quality control system for signatures. The signatures discharged one after another from the rotary press outside the figure pass through the folding machine (not shown) and are conveyed in a state of being overlaid on the conveyors 1, 2, 3, and 4. Note that the signature generally means a printed paper that is folded, but here, including a paper that is not folded by printed paper, includes all the paper that is collected and bound by a stacker bundler. Meaning.

  On the conveyor 3, a signature extracting device 5 is arranged. As the signature extraction device 5, a known signature extraction device can be used. 2 is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-305942, and this signature extracting device 5 is a spatula portion 6 that can be inserted into the lower surface of a conveyed signature. And a clamp portion 7 that can be opened and closed to clamp the signature riding on the spatula portion 6 from the upper surface side of the signature against the spatula portion 6. The clamped signature is placed on a predetermined track 8. The clamp is released at a position indicated by a one-dot chain line in FIG. 2 and is transferred to the upper conveyor belt 9. Adjacent to the upper conveyor belt 9, the conveyor belt of the inspection signature conveyor 10 (FIG. 1) is disposed (not shown in FIG. 2), and the signature for conveying the upper conveyor belt 9 is the inspection. The signature is conveyed to the inspection section outside the figure by the signature conveying device 10.

  As shown in FIG. 2, the 1st marking apparatus 11 which marks 1st identification information on the signature extracted by the signature extraction apparatus 5 is provided. The first marking device 11 is attached to the signature extracting device 5.

  The illustrated first marking device 11 is a stamp type marking device, and can print date, time, count-up numerical value, and the like. The count-up numerical value referred to here is a numerical value that increases each time printing is performed. Accordingly, individual numerical values indicating the order are printed on the extracted signatures in the order of extraction.

  The stamp type marking device 11 shown in FIG. 2 supports the stamp 12 so that it can be moved up and down by the drive of the cylinder 13 connecting the stamp 12, and when the stamp 12 moves down, the stamp is marked with a date. Print time, count-up values.

  As shown in FIG. 3, a stacker bundler 16 is disposed downstream of the signature extraction device 5 in the signature conveyance direction (← direction in FIG. 2). The signature P received from the conveyor 3 and conveyed on the conveyor 4 is crushed by the upper and lower nip rollers 17 and 17 when passing through the press machine 15 of the stacker bundler 16, and is then moved on the conveyor 4. Be transported. A known apparatus can be used for the stacker bundler 16.

  The stacker bundler 16 is a device for creating a bundle of a predetermined number of signatures and banding the created bundle. In general, the stacker bundler 16 creates a small bundle S1 by accumulating a certain number of signatures and a back cutting device 18 that temporarily dams a row of signatures conveyed on the conveyor 4. A bundle creating unit 20 that further stacks the small bundles S1 accumulated in the unit 19 and the small bundle creating unit 19, and a bundling unit 21 that bands the large bundle S2 created by the large bundle creating unit 20 with a binding band. (Refer to FIG. 4). The small bundle S1 created by the small bundle creating unit 19 is sent to the large bundle creating unit 20 by the pusher 19a. The large bundle S2 created by the large bundle creating unit 20 is conveyed to the binding position of the binding unit 21 by appropriate means such as chain conveyance. In addition, in FIG. 3, the code | symbol 22 is a press apparatus for pressing large bundle S2 in the case of banding.

  A counter 40 that counts the number of signatures conveyed on the conveyor can be incorporated in the control unit 41 that controls the stacker bundler 16.

  For example, as described in the background art above, the counter 40 is not illustrated, but the counter circuit of the control unit 41 outputs a pulse signal output when the blades of the impeller of the folding machine cross the transmitted light of the transmission type photoelectric switch. It can be counted by a counter 40 composed of, for example. In this case, the pulse signal is intercepted by the signature conveyed on the conveyor 4 by the photoelectric sensor 23 for confirming the supply of the signature, which is arranged immediately before the small bundle creating unit 19 on the conveyor 4 of the stacker bundler 16. It is input to the counter 40 only during the period.

  As another counting method, for example, the side edge of the signature P conveyed on the conveyor 4, that is, the edge of the signature is detected by the edge detection means, and based on the detection signal from the edge detection means, the counter IC or the like is used. It can also be detected by counting with a configured counter. As the edge detection means, an optical detector that detects a surface height displacement by reflected light of light irradiated on a conveyed signature can be used. Since there is a step in the edge portion of the signature that is conveyed while being shifted, the edge portion of the signature can be detected by detecting the step. The optical detector is preferably one that detects by laser light, but a light emitting diode or other light source can also be used. There is a laser counter as a counter having both an optical detector and a counting means. For example, a laser counter SCATEC-1 manufactured by Baumer electric AG in Switzerland can be used. Note that an ultrasonic detector may be used instead of the optical detector.

  By counting the number of copies by the counter 40, the stacker bundler 16 creates a bundle of signatures of a predetermined number. In the signature extraction device 5, the control unit 42 (FIG. 2) that controls the signature extraction device 5 receives a count signal from the counter 40 of the stacker bundler 16, and receives a predetermined number of signatures from the conveyor 3. Control to extract.

  In the illustrated example, the extraction timing of the signature extraction device 5 is set so as to extract one sheet for each bundle of signatures, and the middle portion of the signature bundle. Based on the count signal detected by the counter 40, the conveyance speed and conveyance distance of the conveyors 1, 2, and 3 (in this example, the distance from the photoelectric sensor position provided on the impeller of the folding machine to the extraction position of the signature extraction device) ), The number of signature bundles to which the signature transported at the extraction position of the signature extraction device 5 should belong can be calculated by calculation. For example, if the signature bundle consists of 100 sheets, the 50th sheet is extracted. Note that such arithmetic processing can be performed in a processing device included in the control unit 42 of the signature extraction device, and an operation command signal for the signature extraction device 5 is sent from the control unit 42. Thus, the signatures to be accumulated in the large bundle S2 as a signature bundle are set to be extracted from the row of signatures conveyed on the conveyor 3.

  As shown in FIG. 4, the stacker bundler 16 is provided with a second marking device 26 that marks the second identification information associated with the first identification information on a binding band that binds a large bundle. The second marking device 26 is disposed on the lateral side of the binding portion 21 of the stacker bundler 16.

  A known marking device can be adopted as the second marking device 26. The second marking device 26 in the illustrated example is an ink jet printer. As this type of industrial inkjet printer, for example, an inkjet printer manufactured by Kishu Giken Kogyo Co., Ltd. is known.

  The binding unit 21 pulls out the binding band 28 wound around the supply reel 27 in the direction of the arrow in the drawing, guides it in the direction of the arrow in the drawing along a predetermined track 29 surrounding the large bundle S2 that is a signature bundle, and The large bundle S2, which is a bundle of bundles, is wound and bound. The second marking device 26 is arranged in the middle of the track 29. When the binding band 28 guided by the detection unit 30 including an attached proximity sensor is detected, the second marking device 26 is matched with the speed at which the binding band is guided. Thus, the binding band is marked.

  The second marking device 26 prints the date, time, and count-up numerical value on the binding band as second identification information. The count-up value printed by the second marking device 26 is the same as the count-up value printed on the signature extracted from the signature bundle to be marked.

  Specifically, at the start of the present system, the counts of the first marking device 11 and the second marking device 26 are reset to “0 (zero)”, and the binding band of the extracted signature and the extracted signature bundle is collected. Each of the markings is sequentially marked, and the printed value is incremented by one each time printing is performed. Accordingly, individual printing is performed for each signature and each signature bundle, and the count-up numerical values printed on a certain signature bundle and the signature extracted from the signature bundle are the same.

  Thus, the first marking device 11 marks the first identification information including a numerical value that is sequentially counted up for each signature extracted by the signature extraction device 5, while the second marking device 26 indicates the extracted folding. The second identification information including the same count-up value as the count-up value marked on the extracted signature is marked on the signature bundle to which the couch belongs.

  According to the quality control system for signatures having the above-described configuration, the first identification information marked on the extracted signature and the second identification information marked on the signature bundle are extracted by collation. It is possible to identify the signature bundle that contains the signature. As a result, even if a printing failure or the like is found at the delivery destination of the signature bundle, only a specific signature bundle need be inspected, and it is not necessary to inspect all the signature bundles.

  In the above embodiment, the stamp-type marking device constituting the first marking device does not control the content of printing from the outside, and the second marking device 26 and the signature from which the first identification information is extracted In this method, identification information is sequentially marked independently without sharing data through an interface or the like. Therefore, associating the second identification information with the first identification information is such that, as in the example of the above embodiment, one signature is extracted from one signature bundle for all signature bundles, and It is obtained by marking individual signature information common to a signature bundle and signatures extracted from the signature bundle.

  In place of the first embodiment, the first marking device is a marking device whose printing content can be controlled based on an external signal, for example, an ink jet printer similar to the ink jet printer constituting the second marking device in the first embodiment. The first marking device and the second marking device are connected to the first identification information marked on the predetermined signature extracted by the common control device 25, and the folding to which the extracted signature belongs. You may control so that common identification information may be included in the 2nd identification information marked on the binding band of a bundle.

  In the above embodiment, a stamp type or an ink jet type is exemplified as the marking device. However, the marking device is not limited thereto, and other marking devices such as a labeling device to which a label such as a barcode label is attached may be employed.

  The signature extraction device is not limited to the signature extraction device 5 of the above-described embodiment, but can adopt a signature extraction device of another aspect, for example, a signature extraction device 5A of the type shown in FIG. You can also A signature extracting device 5A shown in FIG. 5 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-199468, and a marking device 31 is attached to the signature extracting device 5A. The signature extraction device 5A includes an instantaneous stopper 32 that holds and stops at least one signature from both sides so as to widen the interval between the signature rows that are transported out of the conveyor 3 and overlapped, and the folded folding. A guide spatula 33 that advances between the rows of guides and guides the signatures that follow between the rows from the conveyor 3 in the extraction direction, a sampling conveyor 34 that receives and transports the signatures guided by the guide spars 33, and a sampling conveyor 34 has at least two trays 35 and 36 for receiving the signatures conveyed by 34, and the extraction conveyor 34 can hold the signatures conveyed on the extraction conveyor 34 and is supported in a swingable manner. The signature is discharged to one of the trays 35 or 36 by changing the swinging angle or the conveying direction of the extraction conveyor 34. A marking device 31 illustrated in FIG. 5 is an ink jet printer, and is disposed on an intermediate conveyance conveyor 37 that passes a signature from the sampling conveyor 34 to the tray 36.

  The association of the second identification information with the first identification information is such that symbols, numbers, barcodes can be identified so as to identify in which bundle the signature with the first identification information should be included. What is necessary is just to be linked | related by etc.

  Further, the counter is not limited to the one provided in the stacker bundler, and may be provided separately from the counter of the stacker bundler. In addition, the device for obtaining a signal corresponding to the number of copies of the signature for the counter to count the number of copies is not limited to the photoelectric sensor or laser counter provided in the impeller as described above, and one copy of the signature to be conveyed. It is only necessary that one signal can be generated for.

  In the above example, the stacker bundler is illustrated as a so-called horizontal stacker bundler that binds a bundle of signatures stacked in a state in which the signatures are laid sideways (horizontal direction). A so-called saddle type stacker bundler that binds the bundle of signatures accumulated in a state can also be applied.
