Description

Technical Field

[0001] The present invention relates to an apparatus for manufacturing a cardboard sheet, a method for manufacturing a cardboard sheet, and a printer for managing a cardboard sheet base paper. In particular, the present invention relates to a technique capable of efficiently managing the cardboard base paper during use in the manufacture of cardboard sheets.

Background Art

[0002] Conventionally, production information and the like of cardboard sheets manufactured by a cardboard sheet manufacturing apparatus (so-called corrugator) have been managed (for example, Patent Document 1). In recent years, for cardboard sheets manufactured by a corrugator, higher-level quality control has been demanded regarding the state of bonding with adhesive between the core paper and the liner, the accuracy of processing dimensions by a slitter or cutter device, and the like. Against such a background, in a box manufacturing process of processing a cardboard sheet manufactured by a corrugator into a box, and further in a scene where the manufactured box is used by an end user, it is desired to be able to collate information when each cardboard sheet was manufactured by the corrugator. That is, it is desired to ensure traceability.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Patent Document 1 discloses a cardboard sheet manufacturing apparatus that appropriately prints individual identification information on each cardboard sheet in the manufacturing process of cardboard sheets. Specifically, a printing apparatus for printing individual identification information on a cardboard sheet is provided at a position downstream of a cutter device, and the printing apparatus prints individual identification information on each cardboard sheet.

[0005] The inventor of the present application has been considering the management of the corrugated paper base material (corrugated base paper) in the manufacturing process of corrugated paper sheets, rather than the traceability problem of each corrugated paper sheet. To explain further, when manufacturing corrugated paper sheets, roll-shaped base paper (corrugated base paper) is used. When the corrugated base paper is carried into (stored in) the factory (the corrugated paper sheet manufacturing factory), a barcode seal for identifying each base paper is attached to the cover (coating paper) covering the outside of the corrugated base paper, and each base paper can be easily identified by scanning the barcode of each base paper. On the other hand, when replacing it with another base paper during the use of the base paper in the factory, the partially used base paper during use has to be returned to the warehouse. At this time, the cover (coating paper) has already been removed and no barcode seal is attached. Therefore, currently, handwritten characters that can be recognized by people are written on the partially used base paper during use to identify the partially used base paper during use.

[0006] Since this is the current situation, no one has particularly felt a problem with it. However, the inventor of the present application noticed that in this case, if there is a mistake in writing the handwritten characters, it will be difficult to identify the base paper during use, and even if the handwritten characters are written accurately, they are not suitable for computer management. In such a situation, while the inventor of the present application was earnestly studying, he came up with a technology that can efficiently manage the corrugated base paper during use and thus arrived at the present invention.

[0007] The present invention has been made in view of such a point, and its main object is to provide a corrugated paper sheet manufacturing apparatus, a corrugated paper sheet manufacturing method, and a printer for managing corrugated base paper that can efficiently manage the corrugated base paper during use.

[0013] In a preferred embodiment, after the step of printing, a step of feeding the paper roll on which the barcode is printed into a production line for manufacturing cardboard sheets is further performed. Thereafter, a step of returning the paper roll in use to the warehouse is performed. The printer with a scanner has a communication function for transmitting and receiving data. In the step of returning, a step of scanning the barcode on the paper roll in use is performed, and information data of the paper roll in use is transmitted to a computer for a paper management system.

[0014] The management method according to the present invention is a method for managing cardboard base paper for manufacturing cardboard sheets, and includes a step of reading, with a scanner, a barcode displayed on a paper roll around which the base paper of the cardboard sheet is wound, a step of printing the barcode read by the scanner on the side surface of the paper roll, and a step of scanning the barcode on the paper roll in use when returning the paper roll in use to the warehouse.

[0015] In a preferred embodiment, the step of reading with the scanner and the step of printing are performed by a printer with a scanner. In the step of printing on the side surface of the paper roll, the barcode is printed in a region near the core on the side surface of the paper roll.

Effect of the Invention

[0020] In the present invention, a barcode attached to a paper roll can be read by a scanner unit provided in a paper management printer, and the barcode can be printed on the side surface of the paper roll. Therefore, even when the paper in use is returned to the warehouse, since the barcode identifying the paper roll is printed on the side surface of the paper roll, when the barcode is scanned when the paper roll is used again, the identification of the paper roll is completed. Also, since the barcode is printed on the side surface of the paper roll, no problem occurs even when the paper roll is used, and it is also possible to return it to the warehouse again. Further, the management of the paper roll in use becomes much more accurate and convenient than writing identification characters by hand on the paper roll in use. As a result, according to the present invention, the management of the paper roll (corrugated paper) in use can be efficiently performed.

Mode for Carrying Out the Invention

[0022] The inventor of the present application noticed that when managing the cardboard sheet base paper (base paper roll), it is a big problem that the seal (barcode - attached seal) pasted on the cover (coated paper) covering the base paper roll disappears when it enters the factory. Then, the inventor thought that if a printer that can scan the barcode for identifying the base paper roll and print the scanned barcode was developed, the management of the base paper roll would become much easier. Specifically, the inventor realized that if the barcode is printed near the center of the side surface of the base paper roll, the cardboard base paper (base paper roll) can be managed even when the base paper roll in use (incomplete base paper) is returned to the warehouse (or even when it is further put into the factory). Also, since the side surface of the base paper roll is a part that is not used in the finished cardboard product, there is no problem in printing the barcode there. And by printing the barcode near the center of the side surface of the base paper roll, the inventor noticed that the barcode can be used until the base paper roll is used up, which is convenient, and thus the present invention was achieved.

[0023] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following drawings, for the sake of simplicity of explanation, members and parts having the same function are denoted by the same reference numerals, and redundant explanations may be omitted or simplified. Also, the dimensional relationships (length, width, thickness, etc.) in each figure may not necessarily accurately reflect the actual dimensional relationships. In addition, matters other than those specifically mentioned in this specification and that are necessary for the implementation of the present invention can be grasped as design matters of those skilled in the art based on the prior art in the relevant field. The present invention can be implemented based on the content disclosed in this specification and the drawings and the common general knowledge in the relevant field. This can be done. In addition, the present invention is not limited to the following embodiments.

[0024] FIG. 1 is a flowchart for explaining a method for managing corrugated cardboard base paper according to an embodiment of the present invention. FIG. 2 shows an example of a management screen of a corrugated cardboard base paper management system. And FIG. 3 shows a label 70 on which a barcode 75 for identifying the corrugated cardboard base paper (base paper roll) is displayed.

[0025] The method for managing corrugated cardboard base paper in the embodiment of the present invention is a part of the process of a method for manufacturing corrugated cardboard sheets. The method for managing corrugated cardboard base paper in this embodiment is first to prepare a base paper roll around which the base paper of the corrugated cardboard sheet is wound, and then read the barcode attached to the base paper roll with a scanner, and then print the read barcode on the side surface of the base paper roll. This will be further described below.

[0026] As shown in FIG. 1, first, a base paper roll, which is corrugated cardboard base paper, is carried into (stored in) the warehouse of the corrugated cardboard sheet manufacturing factory (step S200). FIG. 2 is an example of a management screen (50) of a corrugated cardboard base paper management system. An order number is assigned to the order of the corrugated cardboard base paper (base paper roll), and the order of the base paper is executed.

[0027] In addition, when ordering the base paper, a specific label 70 for identifying the received base paper shown in FIG. 3 is issued. The specific label 70 is composed of a seal paper 71, and a barcode 75 for identifying the base paper is displayed on the seal paper 71. In addition, information other than the barcode 75 (base paper information) is also displayed on the seal paper 71. The barcode 75 shown in FIG. 3 is of the ITF (Interleaved 2 of 5) type, but other barcodes (for example, JAN (EAN, UPC), CODE39, CODE128, NW-7) may also be used, or a two-dimensional barcode (for example, QR code (registered trademark)) may be used.

[0028] As shown in FIG. 4, when there is an order for the base paper roll 10, it is transported from the paper mill to the corrugated sheet manufacturing factory by a transport vehicle 90 (for example, a truck). As shown in FIG. 5, the specific label 70 (seal of the barcode 75) shown in FIG. 3 is attached to the base paper roll 10. Specifically, a cover (coating paper) is formed on the outer side (surface) of the base paper roll 10, and the specific label 70 (barcode 75) is attached to the cover. By reading this barcode 75 with a barcode reader (scanner), the base paper roll 10 can be identified.

[0029] When the base paper roll 10 is carried into the corrugated sheet manufacturing factory (or its warehouse), the base paper roll 10 can be prepared (step S200). Therefore, the barcode 75 of each specific label 70 of the carried-in (stored) base paper roll 10 is read with a barcode reader (scanner) (step S220). Next, based on the data of the read barcode 75, a barcode (25) is printed on the side surface of the base paper roll 10 (step S240). Specifically, as shown in FIG. 6, the barcode 25 is printed in a region 17 near the core part 15 (cylindrical center part) of the side surface 13 of the base paper roll 10. In FIG. 6, a printed portion (printed matter) 20 including the barcode 25 is shown, and the printed portion (printed information, printed matter) 20 may include only the barcode 25, or may include the barcode 25 and other information (base paper information, manufacturing information, etc.).

[0030] In the configuration of this embodiment, the region 17 near the core 15 on the side surface 13 of the base paper roll 10 is a region that extends from a position half the radius of the base paper roll 10 toward the center. If a barcode 25 is printed on the outer edge side (the side far from the center) of the side surface 13 of the base paper roll 10, when the base paper roll 10 is being used in the manufacturing process (when the base paper is being fed out from the base paper roll 10), the barcode 25 will disappear quickly. Therefore, it is preferable to print it in the region 17 near the core 15. The radius of the base paper roll 10 is typically 350 to 1100 mm. And in a preferred example, the barcode 25 is preferably printed at a position slightly away from the core 15 (for example, in the vicinity of a position about 150 to 250 mm in the diametrical direction). The closer the printing is to the core 15, the longer the barcode 25 can be displayed even when the base paper roll 10 is used in the manufacturing process. And as shown in FIG. 1, after the barcode 25 is printed on the side surface 13 (step S240), the printed base paper roll 10 is moved to (issued from) the warehouse of the manufacturing factory (step S300).

[0031] In the configuration of this embodiment, the base paper barcode scanning step (S220) and the base paper barcode printing step (S240) shown in FIG. 1 are preferably performed by a printer (base paper management printer) equipped with a scanner unit for scanning the barcode. FIG. 7 is a block diagram for explaining the configuration of the base paper management printer 100 of this embodiment.

[0032] The printer (paper roll management printer) 100 shown in Fig. 7 is composed of a scanner unit 32 that scans the barcode 75 attached to the paper roll 10, and a printing unit 30 that prints the barcode 25 on the side surface 13 of the paper roll 10 based on the data of the barcode 75 read by the scanner unit 32. The printing unit 30 in the paper roll management printer 100 of this embodiment is an inkjet printer, and an inkjet head is provided in the printing unit 30. In the configuration of this embodiment, although the printing unit 30 adopts the inkjet printer method, as long as the barcode 25 can be printed on the side surface 13 of the paper roll 10, other methods (for example, laser printers, etc.) can also be adopted.

[0033] The scanner unit 32 can be connected by wireless communication separately from the printing unit 30. However, the paper roll management printer 100 of this embodiment has a structure in which the scanner unit 32 and the printing unit 30 are arranged in one housing, and while the barcode 75 is scanned by the scanner unit 32, the barcode 25 can be printed on the side surface 13 (area 17) of the paper roll 10 by the printing unit 30. It is preferable that the housing containing the scanner unit 32 and the printing unit 30 is provided with a gripping part that allows an operator to hold and fix the paper roll management printer 100 by hand for convenience when printing the barcode 25 on the side surface 13 (area 17) of the paper roll 10.

[0034] In addition, in the base paper management printer 100 of the present embodiment, a communication unit 34 may be provided so that step barcode information obtained by scanning barcode 75 and / or step (fact) barcode information obtained by printing barcode 25 can be communicated (transmitted and received) with an external information terminal. Such an information terminal is a portable information terminal (tablet terminal, smartphone, mobile phone, notebook personal computer (notebook PC)) or a personal computer (PC) in which a cardboard base paper management system (software) for managing base paper is introduced. Communication (transmission and reception) with an external information terminal may be via wired communication (wired LAN), but considering work in a warehouse or factory, wireless communication (wireless LAN, Wi-Fi, etc.) is preferred. Further, a display may be provided on the base paper management printer 100, or such a display may be connected to the base paper management printer 100 wirelessly (or wired). By providing a display (screen display device), it becomes possible to display work procedures (work manuals), base paper information, base paper management information, production schedule information, etc., which is convenient for the operator. Such a display (screen display device) may be, for example, a liquid crystal display device, an organic EL device, etc., but may also be a glass-type (eyeglass-type) display or a projection-type display.

[0035] FIG. 8 schematically shows the configuration of a cardboard sheet manufacturing apparatus 500 (so-called corrugator) of the present embodiment. FIG. 9 shows a flowchart for explaining the manufacturing method of the cardboard sheet of the present embodiment.

[0036] The cardboard sheet manufacturing apparatus 500 shown in FIG. 8 is an apparatus for manufacturing a cardboard sheet 510. The cardboard sheet manufacturing apparatus 500 of the present embodiment includes a single facer apparatus 501 and a double facer apparatus 503. The single facer apparatus 501 is an apparatus for producing a single-sided cardboard sheet 105 by bonding a core 104 with formed steps and a liner 102 (here, the back liner). The double facer apparatus 503 is an apparatus for producing a double-sided cardboard sheet 107 by bonding another liner 103 (here, the front liner) to the single-sided cardboard sheet 105.

[0037] In the configuration of the present embodiment, a first base paper roll 10A including a first base paper sheet (core base paper) 101 for producing the core 104, a second base paper roll 10B (10) including a liner 102 (back liner), and a third base paper roll 10C (10) including another liner (front liner) 103 are used for manufacturing a cardboard sheet. The first base paper roll 10A, the second base paper roll 10B, and the third base paper roll 10C are supplied from a warehouse as shown by an arrow 19 (raw paper payout step S300 in FIG. 1) and set on a mill roll stand (not shown).

[0038] In the present embodiment, on the side surface 13 of the base paper roll 10 (10A to 10C), a barcode 25 (printing information 20) is printed by the base paper management printer 100. In at least one of the base paper rolls 10A to 10C, the barcode 25 is printed on the side surface 13 of the base paper roll 10, but it is preferable that the barcode 25 is printed on the side surface 13 in all of the base paper rolls 10A to 10C. Further, it is preferable that the barcode 25 is printed on the side surface 13 of all the base paper rolls 10 (10A to 10C) in the warehouse and the manufacturing factory for manufacturing the cardboard sheet.

[0039] In the example shown in FIG. 8, the first base paper roll 10A supplies the first base paper sheet (core base paper) 101. Next, the core base paper is formed into a corrugated shape and glued to make the core 104. On the other hand, the liner 102 (back liner) is supplied from the second base paper roll 10B, and in the single facer device 501, the core 104 and the liner 102 (back liner) are bonded together to produce the single-sided corrugated sheet 105. Next, the single-sided corrugated sheet 105 is glued on the other side (sheet 106). Further, another liner (front liner) 103 is supplied from the third base paper roll 10C, and subsequently, in the double facer device 503, the single-sided corrugated sheet 105 and the other liner 103 (front liner) are bonded together to obtain the double-sided corrugated sheet 107. After that, a score line is made with the slitter scorer 505 (sheet 108), and then it is cut with the cutoff 507 (sheet 109), and as a result, the corrugated sheet 510 that becomes the material for making the cardboard box is obtained.

[0040] Also, an example of the flow of the base paper roll 10 in this embodiment is as shown in FIG. 9. First, the base paper is ordered (step S100), and at that stage, the label 70 (barcode 75) shown in FIG. 3 is issued (step S120). When ordering the base paper, the roll number (individual number) is automatically numbered. The order data is transmitted to the base paper management system together with the roll number (individual number), and the label issuance or incoming shipment scheduled data is prepared in advance. The label 70 (barcode 75) is attached to the base paper roll 10 as shown in FIG. 5.

[0041] After that, the base paper roll 10 is carried in (stocked) (step S200). The barcode 75 of the corresponding label 70 is read, or selected from the incoming shipment scheduled data to confirm the stock data. Subsequently, the base paper barcode 75 is scanned by the base paper management printer 100 (step S220), and then the base paper barcode 25 is printed on the side surface 13 of the base paper roll 10 by the base paper management printer 100 (step S240). After printing on the incoming base paper roll 10, it is moved to the warehouse, and the stock data is received from the base paper management system to record the purchase.

[0042] After that, the base paper roll 10 is dispensed to the manufacturing factory (step S300). The base paper roll 10 is dispensed with the required number from the base paper warehouse according to the base paper hanging schedule. Subsequently, it is loaded (set) into the mill roll stand (not shown) in the factory (step S320). Before hanging the base paper or after hanging it on the mill roll stand, the barcode 25 (75) of the label 20 (70) is read to recognize the base paper 10 to be used. It is ensured that the base paper 10 is as planned, and the base paper 10 is loaded and recognized until the rod m (rod meter) is filled.

[0043] Subsequently, lamination is performed in the corrugated sheet manufacturing process. When the lamination process is completed (step S340), the base paper roll 10 in use is returned to the storage location (step S360). When the lamination is completed, the individual information such as the remaining m (remaining meter), usage date, and usage times of each base paper 10 is updated. Also, the base paper barcode 25 is scanned, and by synchronizing the data with the corrugated base paper management system, the inventory data can be updated (step S400). By executing the inventory data synchronization process every day, the individual information of the base paper (inventory quantity, remaining m, etc.) is synchronized in the management system.

[0044] Figures 10 to 13 show an example of the configuration of the base paper management printer 100 according to the present embodiment. Figure 10 shows the upper surface configuration of the printer 100, and Figure 11 shows the front configuration (cross-sectional view) of the printer 100. Figure 12 shows the side configuration (cross-sectional view of the right side) of the printer 100. Figure 13 shows the side configuration (left side) of the printer 100.

[0045] The illustrated printer 100 includes a scanner unit 32 capable of reading a barcode 75(25), and a printing unit 30 capable of printing a barcode 25. The printing unit 30 includes an inkjet head 30a. The printing unit 30 and the scanner unit 32 are fixed by a housing 35. Further, the printer 100 of the present embodiment is provided with a gripping portion 39 having a gripping bar 39a for convenience when printing the barcode 25 on the side surface 13 of the paper sheet 10. With the operator holding the gripping portion 39(39a) by hand, the barcode 25(printing information 20) can be printed in the printing area 31(the movable area / range of the inkjet head 30a) shown in FIG. 10.

[0046] FIG. 14 is a flow for explaining an example of the corrugated cardboard sheet management process according to the present embodiment. The sheet management process(management flow) can be divided into an arrangement phase 600, an input phase 700, and an inventory phase 800.

[0047] First, in the arrangement phase 600, based on the order for the sheet list(step 601), order data 604 is transmitted, and a sheet label 70 is issued and the scheduled arrival data is transmitted(step 605). The barcode 75 is read(step 606), and the sheet 10 is received(step 609). Thereby, the inventory data 608 is transmitted, and the sheet purchase is recorded together with the order for the sheet list(step 601)(step 602). Then, based on the inventory data 608, as shown in FIG. 4, the sheet roll 10 is delivered.

[0048] In the input phase 700, based on the laminating plan 701, a base paper hanging schedule 702 is created. Then, based on the base paper hanging schedule 702, the base paper is dispensed (step 703). At that time, individual recognition by barcode reading is executed (step 704). Subsequently, the base paper is hung and used for corrugated (step 705). In the use for corrugated, the data of the usage meter is acquired and the remaining length is updated (step 706). In this input phase 700, at the time of dispensing the base paper (loop from arrow 708 to 709), the partial base paper 10E is input based on the updated remaining length, and the used-up base paper 10F is discarded.

[0049] In the inventory phase 800, the transmission of the base paper inventory data is performed (step 805), and based on the outgoing / stock data 802, the data of the base paper inventory 801 is synchronized and updated to the latest (real-time, same-day inventory).

[0050] Here, the operation of the printer 100 shown in FIG. 10 etc. will be exemplarily described as follows. (1) Turn on the power of the printer 100. (2) Turn on the control panel (control device, control circuit) of the printer 100. (3) Transfer the barcode in which the base paper information is stored (transfer of original data). (4) After the information of the barcode 75 has been read, a startable signal is issued on the condition that the moving box (inkjet head 30a) is at the home position. (5) Press the start button of the printer 100 (portable printer). (6) The moving box in which the inkjet gun (inkjet head 30a) and the barcode reader 32 are integrated moves by the slide cylinder (speed 2 meters / minute). (7) When the limit piece of the moving box hits the limit switch, the inkjet gun (inkjet head 30a) operates. (8) The moving box stops operating at the forward limit and enters the backward operation. (9) The operation of the barcode reader is turned on after a specified number of timer seconds. (10) When the barcode reader 32 reads a barcode 75 (one-dimensional ITF or two-dimensional QR code), it transfers the recognized barcode information to the controller. (11) After the transfer is completed, it accepts the next data. (12) Then, these operations are repeated.

[0051] And the method of raw paper data management is exemplified as follows. (1) Move the newly loaded raw paper from the paper manufacturer to the designated temporary storage area. (2) Read the barcode attached to the new raw paper at the designated temporary storage area with a barcode reader, and transfer the data to the controller panel of the printer 100. (Basically, for one truckload of Track 1, the barcode 75 is read collectively and transferred to the host computer and the controller panel of the printer 100. That is, it corresponds to step (3) in the operation of the above printer 100) (3) Print the barcode 25 for every 10 raw papers (here, print the barcode 25 at one location on each side of the side 13 of 10 raw papers) (4) After the printing of the barcode 25 by the printer 100 is completed, put the raw paper 10 into the warehouse. (5) During production, pay out the raw paper 10 based on the schedule. (6) Read the barcode 25 printed on the paid-out raw paper 10 with the barcode reader 32. After verifying and confirming with the raw paper data of the production management device, prepare a set of splices for splicing the next order of raw paper to the currently produced raw paper. (7) If the printed part of the barcode 25 on the raw paper 10 is damaged and unreadable, obtain the raw paper data from the collator management device and print (mark) the barcode 25.

[0052] As described above, using the method of this embodiment, it is possible to perform a method for managing corrugated base paper and a method for manufacturing corrugated sheets. In the configuration of the embodiment of the present invention, the barcode 75 attached to the base paper roll 10 is read by the scanner unit 32 of the base paper management printer 100 provided with the scanner unit 32, and the barcode 75 (25) can be printed on the side surface 13 of the base paper roll 10. Therefore, even when the base paper 10 in use is returned to the warehouse, since the barcode 25 for identifying the base paper roll is printed on the side surface 13 of the base paper roll 10, when the barcode 25 is scanned when the base paper roll 10 is used again, the identification of the base paper roll 10 is completed. Further, since the barcode 25 is printed on the side surface 13 of the base paper roll 10, no problem occurs even when the base paper roll 10 is used, and it is also possible to return it to the warehouse again. In addition, the management of the base paper roll 10 in use becomes much more accurate and convenient than writing identification characters by hand on the base paper roll 10 in use. As a result, it is possible to efficiently manage the base paper roll 10 (corrugated base paper) in use.

[0053] As described above, the present invention has been explained by way of preferred embodiments. However, such descriptions are not limiting matters, and of course, various modifications are possible. Further, although the technology of this embodiment is most suitable for the management technology of corrugated base paper and the manufacturing technology of corrugated sheets, in addition, if the barcode printed on the outer packaging disappears, it may be applied to products for which it is difficult to identify the contents. Examples of such products include the following. For example, when products made by a box-making machine (flexo folder gluer) are stacked on a pallet by a robot, the last pallet of the order has a different planned quantity, so the operator counts the number of bundles and manually changes the product quantity on the placard. If it were possible to print the actual pallet quantity and barcode on the product placard, the quantity management per pallet would be accurate. Furthermore, if the logistics staff can read the barcode on the placard when placing the product in the product warehouse and transfer the location data to the office using GPS as well, the customer name, product name, quantity, and production completion time per pallet in the product warehouse will be accurate, enabling the inventory management of the product warehouse and the real rationalization of shipping instructions to proceed. According to the method of the embodiment of the present invention, it is possible to accurately manage in real time the quantity management, etc. per pallet of the completed Type A corrugated case.
