Description

[Technical Field]

[0001] The present invention relates to a recording device that forms images and writes data on labels with RFID tags arranged on a sheet. [Background technology]

[0002] As disclosed in Patent Document 1, a recording device is known that forms an image on a label and writes data to an RFID tag attached to a rolled backing paper, the label having an embedded RFID tag. When writing data to an RFID tag, if there is a problem with the RFID tag, the data writing may fail. In such cases, an error pattern is printed on the label to make it easy to identify the label on which data writing has failed.

[0003] In a configuration such as that of Patent Document 1, in which the read / write antenna used to write to the RFID tag is located upstream of the thermal head that records on the label, an error pattern can be recorded on the label after it is determined that writing data to the RFID tag has failed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-88705 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a configuration where the antenna that writes to the RFID tag is located downstream of the recording head that records on the label, when it is determined that data writing to the RFID tag has failed, the label is downstream of the recording head, so it is necessary to backfeed the label to which data writing has failed upstream of the recording head and then record an error pattern on the label to which data writing has failed.

[0006] However, the number of labels that must be backfed to record an error pattern on a label where data writing has failed varies depending on the size and spacing of the labels used. Also, the position of the label's leading edge when a writing failure is detected varies depending on the position of the RFID tag within the label. Therefore, there is an issue that always backfeeding the same distance cannot accommodate a variety of labels.

[0007] Therefore, an object of the present invention is to provide a recording device that, when it detects a label on which writing to an RFID tag has failed, performs backfeed according to the label and prints an error pattern on the label on which writing to an RFID tag has failed. [Means for solving the problem]

[0008] To achieve the above object, a recording method for a recording device according to one aspect of the present invention includes the following steps: an acquisition step of acquiring a label length, which is the length of the labels in the feed direction, and a label spacing, which is the distance between the rear end of a given label and the front end of the label following the given label in the feed direction, a setting step of setting the number of labels to be backfed based on the label length and label spacing acquired in the acquisition step, a receiving step of receiving image data and write data, a recording step of using a recording device to record an image based on the image data on the label being fed in the feed direction, a writing step of writing data based on the write data to an RFID tag included in the label recorded in the recording step, a determination step of determining whether the writing step has been completed successfully, a backfeed step of backfeeding the number of labels set in the setting step when it is determined in the determination step that the writing step for the given RFID tag has not been completed successfully, and an error pattern recording step of, after the backfeed step, recording an error pattern, indicating that the writing step has not been completed successfully, on a label including the given RFID tag. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a recording device that, when a label for which writing to an RFID tag has failed is detected, performs backfeed according to the label and prints an error pattern on the label for which writing to an RFID tag has failed.

[0011] Preferred embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0012] <Configuration of recording device> First, the configuration of the recording apparatus according to this embodiment will be described with reference to FIGS. Fig. 1 is a diagram showing the overall configuration of a recording system including a recording apparatus according to this embodiment, and Fig. 2 is a schematic diagram showing the general internal configuration of the recording apparatus.

[0013] 1, the recording system includes a recording device 100 and a host computer 104, which are communicatively connected via an interface 105. The recording device 100 includes a device main body 101 and a roll sheet holder 103 into which a roll 200 on which a sheet 200S is wound is loaded. The device main body 101 is provided with an operation panel 102. The operation panel 102 has a display unit formed of an LCD or the like and an input unit formed of a touch panel, buttons, etc.

[0014] 1 shows an example in which the interface 105 connecting the recording device 100 and the host computer 104 uses a printer cable, but it may also be connected via a network such as a LAN. The communication connection may be wired or wireless. The interface 105 functions as a receiving means by which the recording device 100 receives data from the outside.

[0015] The host computer 104 is a computer terminal that supplies job data to the recording device 100, and is configured as a personal computer, a smartphone, a server device, or the like. A plurality of host computers 104 may be connected to one recording device 100.

[0016] The recording device 100 performs a recording operation on the sheet 200S based on job data received from the host computer 104. The recording operation includes an image forming operation on the labels arranged on the sheet 200S and an operation of reading and writing data from and to the RFID tags embedded in the labels. For example, an item identification code of a predetermined number of digits used in a POS system or a distribution management system that manages product information is recorded on the label surface and written to the RFID tag. The recording device 100 performs the above-mentioned recording operation while transporting the sheet 200S pulled out from the roll 200 by a transport unit 201 shown in FIG. 2.

[0017] In this embodiment, the job data is described as including both data to be recorded on the label and data to be written on the RFID tag, but the data to be recorded may be sent as job data and the data to be written may be sent separately from the job data.

[0018] As shown in Fig. 2, the sheet 200S pulled out from the roll 200 loaded in the roll sheet holder 103 passes through a guide unit 211 and is supplied to a conveying unit 201. The guide unit 211 is a mechanism for restricting the position of the sheet 200S in the width direction perpendicular to a predetermined conveying direction of the sheet 200S so that it does not exceed a predetermined range. The direction indicated by A in the figure (conveying direction A) is the predetermined conveying direction. In Fig. 2, the sheet 200S is indicated by a dashed line.

[0019] The transport unit 201 drives the transport rollers 202 and the transport belt 207 by a driving force transmitted from a drive motor 206. A fan 208 is provided inside the transport unit 201, and the sheet 200S is attracted to the transport belt 207 by a negative pressure generated by the fan 208. In this state, the transport unit 201 transports the sheet 200S from the upstream side to the downstream side in the transport direction A.

[0020] A leading edge detection sensor 209 is disposed at a predetermined position upstream of the recording head 210 and the R / W antenna 230 in the conveying direction A. A transmission type sensor is used for the leading edge detection sensor 209, which detects the introduction of the edge of each label arranged on the sheet 200S based on differences in light transmittance and outputs a detection signal to the main controller 501 (FIG. 5). In addition, an encoder that counts the conveyance amount of the sheet 200S is provided on, for example, the conveying roller 202.

[0021] The main controller 501 of the recording device 100 manages information about the transport position of each label based on the detection signal obtained from the leading edge detection sensor 209 and the transport amount of the sheet 200S counted by the encoder. The information about the transport position of each label is referenced in the image formation operation by the recording head 210 and the read / write operation by the R / W antenna 230.

[0022] The recording head 210 is held such that a nozzle surface on which a number of nozzles for ejecting ink are arranged faces a sheet surface conveyed by a conveyance belt 207. An ink tank (not shown) is connected to the recording head 210. The recording apparatus 100 causes the recording head 210 to eject ink according to a signal that determines whether ink is ejected for each of a plurality of nozzles of the recording head 210. Thereby, an image is formed (recorded) on the conveyed sheet 200S.

[0023] In the present embodiment, an inkjet recording apparatus using ink as a recording material will be described as an example, but the present invention is not limited to this. The present disclosure is applicable to recording apparatuses of various recording methods such as electrophotographic methods such as thermal printers (sublimation type, thermal transfer type, etc.), dot impact printers, LED printers, and laser printers.

[0024] The R / W antenna 230 as a reading unit and a writing unit outputs radio waves for reading (reading) and writing (writing) data to and from RFID tags respectively incorporated in a plurality of labels arranged on the sheet 200S. In the present embodiment, as shown in FIG. 2, the R / W antenna 230 is provided on the downstream side of the recording head 210 in the conveyance direction A of the sheet 200S.

[0025] The sheet 200S on which image formation by the recording head 210 and data writing by the R / W antenna 230 have been performed is discharged out of the apparatus main body 101 from the sheet discharge port.

[0026] <Label with RFID tag> Next, the label 302 with an RFID tag and the sheet 200S used as a recording medium in the present embodiment will be described. FIG. 3 is a diagram showing the sheet 200S. FIG. 4 is a diagram for explaining the configuration of the label 302.

[0027] As shown in Fig. 3, roll 200 is formed by winding up a continuous sheet 200S. Sheet 200S is configured by arranging a plurality of labels 302 at equal intervals on substrate 301. Substrate 301 has, for example, a release surface, on which labels 302 are removably attached via an adhesive layer.

[0028] As shown in Fig. 4, the label 302 has an RFID tag 405 inside. The RFID tag 405 is also called an inlay or an inlet. One RFID tag 405 is built into one label 302. The RFID tag 405 is composed of an IC chip 403 and an antenna 404.

[0029] The IC chip 403 includes a controller and a memory. The controller transmits and receives data to and from the R / W antenna 230 (reader / writer) of the recording device 100 in a predetermined procedure. It also transmits responses to processing requests from the recording device 100. Processing requests include requests to read data from memory and requests to write data to memory.

[0030] The memory in the IC chip 403 has areas such as TID (Tag identifier) ​​memory, EPC (Electronic product code) memory, user memory, and reserved memory. The TID memory is an area where a unique value is written to each RFID tag 405 by the manufacturer when the RFID tag 405 is manufactured. The EPC memory is an area where code information for identifying individual RFID tags is stored. The user memory is an area where the user can freely read and write data. The reserved memory is an area for storing password information used for the lock function and the disable (kill) function.

[0031] <Configuration of the control system of the recording device> 5 is a block diagram showing the configuration of a control system of the recording apparatus 100 of this embodiment. As shown in the figure, the recording apparatus 100 has a main controller 501, RAM 502, ROM 503, image buffer memory 504, driver controller 506, etc. Also connected to the main controller 501 are a drive circuit 507, a sensor circuit 509, an RFID controller 510, an operation panel 102, etc. A head drive circuit 505 is connected to the driver controller 506. The recording apparatus 100 performs a conveying operation of the sheet 200S and a recording operation on the label 302 based on control signals from the main controller 501.

[0032] The main controller 501 is a control unit that controls the entire recording device 100 and is composed of a CPU. The main controller 501 executes various processes using the RAM 502 as a work area in accordance with programs stored in the ROM 502. The RAM 502 is a volatile or non-volatile storage area and is used as a work memory, etc. The ROM 503 is a non-volatile storage area that stores the control program for the recording device 100, the program related to this embodiment, etc. The main controller 501 is connected to the host computer 104 via an interface, and transmits and receives signals to and from the host computer 104.

[0033] The image buffer memory 504 is a memory that stores image data transmitted from the host computer 104. The head drive circuit 505 is a drive circuit that drives a heating element (not shown) in the print head 210, and is driven under the control of a driver controller 506. The driver controller 506 controls the head drive circuit 505 so that ink is ejected from the nozzles of the print head 210 based on the bitmap data stored in the image buffer memory 504.

[0034] A drive circuit 507 drives the transport motor 206 of the transport unit 201, and is controlled by the main controller 501. A sensor circuit 509 performs detection operations for various sensors, such as the leading edge detection sensor 209, and transmits the acquired detection signals to the main controller 501. The touch panel and buttons of the operation panel 102 input signals to the main controller 501 in response to user operations. Display control on the LCD is also performed by the main controller 501.

[0035] The RFID controller 510 communicates contactlessly with the RFID tags 405 in the labels 302 arranged on the conveyed sheet 200S, and reads and writes (R / W) data. The RFID controller 510 is controlled by the main controller 501. Data to be written to the RFID tags 405 is supplied from the host computer 104.

[0036] <Functional configuration of the recording device> Next, the functional configuration of the recording device 100 will be described. 6 is a block diagram showing the functions of the recording device 100. As shown in the figure, the recording device 100 has a data acquisition unit 610, an image forming unit 620, a read / write unit 630, a calibration processing unit 640, a conveying speed determination unit 650, an auto / manual setting unit 660, and the like.

[0037] The data acquisition unit 610 acquires recording data for forming an image on the label 302 and writing data for writing to the RFID tag 405. In this embodiment, an example is shown in which the recording data and writing data are supplied from the host computer 104, but data stored in a non-volatile memory (not shown) of the recording device 100 may also be acquired.

[0038] In the image forming operation, the recording device 100 records one page of data on one label 302. Therefore, the recording data for the sheet 200S on which multiple labels 302, 302, ... are arranged includes data for the number of pages corresponding to the number of labels. In the data writing operation, the recording device 100 writes data corresponding to the content to be recorded on each of the labels 302, 302, ... to the RFID tags 405, 405, ... of the multiple labels 302, 302, .... Therefore, the writing data for the sheet 200S on which multiple labels 302 are arranged includes the number of writing data corresponding to the number of labels. However, the amount of data written to each RFID tag 405, 405, ... (the number of digits of the code in the case of an identification code) is the same throughout the series of recording operations.

[0039] The image forming unit 620 forms an image on the recording surface of the labels 302 arranged on the sheet 200S based on the recording data acquired by the data acquisition unit 610. When the label 302 (target label) on which an image is to be formed is transported to a predetermined image forming position, the image forming unit 620 ejects ink from the recording head 210 based on the recording data to form an image on the label surface.

[0040] The read / write unit 630 performs a read process to read data from the RFID tags 405 of the labels 302 arranged on the sheet 200S, and a write process to write individual write data to each RFID tag 405. More specifically, the write process is performed as a set of inventory processing, write processing, and verify processing. In the write process, a locking process may be performed as necessary, or a pause time may be set to limit the continuous output of radio waves.

[0041] The inventory process is a process for detecting the RFID tag 405 to be written to, and is performed by reading unique information from the RFID tag 405. The write process is a process for specifying the TID and EPC and writing data to be written to the target RFID tag. The verify process is a process for confirming whether the data used for writing matches the data actually written, and is a process for reading the written data from the RFID tag 405 and comparing it with the data used for writing. If there is a defect in the IC chip 403 of the RFID tag 405, the write process will not end normally, and a discrepancy will occur between the data read from the RFID tag 405 in the verify process and the data written. A label for which a discrepancy occurs between the read data and the written data in the verify process is determined to be a defective label. Note that a defective label may be determined to be a defective label not based on a single write process failure, but on multiple repeated write process failures.

[0042] <Example 1: Adding to the end of a job> In this embodiment, processing for a case where re-recording and rewriting of defective tag labels is added to the end of a job will be described. An example of this is when a serial number is included in the image to be recorded and used as a product label, with the serial number also written to the RFID tag 405. In such a case, it is sufficient that the labels affixed to each product are distinguished by their serial numbers, and changing the order in which the labels are arranged does not pose any problems in terms of application.

[0043] Here, we will explain the case of processing a job in which numbers "1" to "9" are recorded on multiple labels 302 attached to a sheet 301 as shown in Figure 7, and the numbers recorded on the labels are written to the RFID tag 405 of each label.

[0044] 8 is a schematic diagram showing the positional relationship between the recording head 210 and the R / W antenna 230 inside the recording device 100. The R / W antenna 230 is located downstream of the recording head 210 in the transport direction A. The R / W antenna 230 writes data to the RFID tag 405 of a label after recording by the recording head 210. Therefore, when a label is determined to be a defective tag label at the position of the R / W antenna 230, recording has already been performed on the subsequent label. In FIG. 8, when label 702 is transported below the R / W antenna 230 and determined to be a defective tag label, image recording by the recording head 210 has already been completed on labels 703 and 704, and image recording on label 705 is only partially completed.

[0045] When label 702 is determined to be a defective tag label, image recording and data writing are completed up to label 705, but image recording and data writing are stopped for label 706 and beyond. Next, as shown in FIG. 9 , label 702 is fed backward in the direction of arrow B to recording start position P, and then transported in a predetermined transport direction, overwriting label 702 determined to be a defective tag label with an "X" as an error pattern. Recording continues from label 706 onwards until the end, i.e., printing a "9" on label 709 and writing data. The image recorded on label 702 determined to be a defective tag label, i.e., a "2," is then recorded on label 710 following label 709, and the data is written, completing the job. In other words, image recording and data writing for the label determined to be a defective tag label are added to the end of the job. The process of adding image data and write data to the end of the job data is performed by the main controller 501.

[0046] The operation of moving the label 702 to the recording start position P will be described in detail using Figure 10. When the label 702 is determined to be a defective tag label at the position of the R / W antenna 230, the positional relationship between the label 702 and the R / W antenna 230 becomes as shown in Figure 10(A). From this state, the sheet 200S is fed backward until the leading edge of the label 702 is detected by the leading edge detection sensor 209. When backward feeding starts from the state of Figure 10(A), the leading edge of the fifth sheet, including the label detected by the leading edge detection sensor 209, becomes the leading edge of the label 702.

[0047] In this case, the number of labels that are defective after the start of backfeeding can be calculated as follows: Using the distance D from the R / W antenna 230 to the leading edge detection sensor 209, the label length L in the conveying direction, and the label spacing G, the calculated value is the integer part of N=D÷(L+G)+1.

[0048] For example, when the distance D is 160 mm, the label length L is 30 mm, and the label spacing G is 10 mm, the fifth label detected by the leading edge detection sensor 209 after backfeeding begins corresponds to label 702. If the label determined to be defective at this time is located at the center of the label in the conveyance direction where the R / W antenna 230 is located, the backfeed distance is 175 mm.

[0049] FIG. 10B shows the state in which backfeeding is stopped when the leading edge detection sensor 209 detects the leading edge of the label 702. Because the distance from the leading edge detection sensor 209 to the recording start position P is predetermined, the label 702 is conveyed a predetermined distance to align its leading edge with the recording start position P. This state is shown in FIG. 10C. After aligning the leading edge of the label 702 with the recording start position P, an error pattern is overwritten on the label 702. Note that the backfeed distance required for the leading edge of the label 702 to reach the recording start position P may be calculated using the distance D, label length L, and label spacing G, and the leading edge of the label 702 may be aligned with the recording start position P by backfeeding. Furthermore, the leading edge position of each label detected by the leading edge detection sensor may be stored, and the leading edge of a label determined to be a defective tag label may be backfed to the recording start position P.

[0050] The label length L and label spacing G are set by the user in the host computer 104 or by the user operating the operation panel 102, and are acquired by the main controller 501 for control.

[0051] By recording images in this manner, it is possible to finally output labels on which the numbers "1" to "9" are recorded, as shown in Fig. 11. Furthermore, by overwriting an "x" as error pattern 901 on a label 702 determined to be a defective tag label, it is possible to easily identify the defective tag label. The error pattern 901 can be something other than an "x" as long as it can be determined that the label is a defective tag label.

[0052] In this embodiment, the case where there is one defective tag label has been described, but even if there are multiple defective tag labels, they may be added sequentially to the end of the job.

[0053] 12 shows the case where the label sizes are different. When the distance D is 160 mm, the label length L is 60 mm, and the label spacing G is 10 mm, the third label detected by the leading edge detection sensor 209 after backfeeding begins is the defective TAG label 902. If the R / W antenna 230 is positioned in the center of the label in the conveying direction, the label determined to be defective, the backfeed distance is 190 mm. Thus, when the label length L and label spacing G differ, the number of labels detected as defective by the leading edge detection sensor after backfeeding begins differs, and the distance required to backfeed the leading edge of the defective TAG label to the leading edge detection sensor 209 also differs.

[0054] Example 2: A case where labels are arranged so that their order does not change Next, we will explain the process of arranging labels so that their order remains unchanged. One example of this is when shipping labels for cargo are used, with destination information recorded on the label and written onto an RFID tag, which is then attached to the cargo. When attaching corresponding shipping labels to cargo with different contents transported on a conveyor belt or other device, if the order of the cargo being transported and the order in which the labels should be attached do not match, it becomes difficult to correctly match the cargo with the shipping label. For this reason, even if a defective tag label is detected, the labels are arranged so that their order remains unchanged.

[0055] Here, as in the first embodiment, a case will be described in which numbers "1" to "9" are recorded as images in ascending order on labels, and the numbers recorded on the labels are written as data to the RFID tag of each label.

[0056] In this embodiment, the method for determining defective tag labels is the same as in embodiment 1. As shown in Fig. 13, if label 802 is determined to be a defective tag label, recording on labels 806 and onwards, for which recording has not yet begun, is stopped. Next, label 802 is fed backward to the recording start position, and then conveyance in a predetermined conveyance direction is started. Then, an X is overwritten on label 802, which has been determined to be a defective tag label, as an error pattern, and X is also overwritten on labels up to label 805. Then, image recording and corresponding data writing are performed for labels 806 and onwards, starting with "2".

[0057] By recording images in this way, it is possible to rearrange and output the labels on which the numbers "1" to "9" are recorded in ascending order, as shown in Fig. 14. Also, by overwriting labels 803 to 805 with an "x" as an error pattern in addition to label 802, which has been determined to be a defective tag label, it becomes easier to identify the labels to be used in ascending order.

[0058] It is also possible to make it possible to execute both the process of embodiment 1 and the process of embodiment 2, and to switch the process when a defective tag label is detected according to the user's settings or instructions. This allows the user to select, depending on the application, whether to place the reprinted label at the end of the job, even if it means changing the label order, or to place the reprinted label so that the label order does not change. Furthermore, it is also possible to select the process of stopping image recording and data writing when a defective tag label is detected.

[0059] Example 3 In this embodiment, the number of labels to be backfed is set based on the label type specified by the user. In the previous embodiments, the label length and label spacing were set by the user, but in this embodiment, the label type is set by the user.

[0060] 15 is a flowchart showing the control of this embodiment. First, in step S101, the user inputs the label type. The label type can be entered by operating a pull-down menu or radio buttons, for example, from a name such as "Label A," a label size such as "4 inch x 3 inch label," or a user-customized setting such as "User Setting 1." This input can be made from the host computer 104, or by operating the operation panel 102.

[0061] Next, in step S102, the main controller 501 acquires the input label type.

[0062] Next, in step S103, the main controller 501 sets the label length and label spacing based on the acquired label type. A table linking label types with label lengths and label spacing is stored in advance in ROM 503, and the main controller 501 references the table stored in ROM 503 and sets the label length and label spacing corresponding to the acquired label type. Note that the table may be stored in ROM 503 inside the recording device 100, or may be referenced from an externally stored table via a network.

[0063] Next, in step S104, the number of labels to be fed back for printing the error pattern is set. The method for setting the number of labels is the same as in the first embodiment.

[0064] By carrying out the above control, the user can set the number of labels to be backfed required to print an error pattern by setting the type of label.

[0065] In addition, it is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally fall within the technical scope of the present invention.
