Description

[Technical Field]

[0001] The present invention relates to an IC tag affixing device for affixing an IC tag to the cover of a booklet, an IC tag affixing method, and a perfect binder equipped with the IC tag affixing device. [Background technology]

[0002] Conventionally, as part of the bookbinding process, a bundle of paper sheets (a bundle of paper sheets) such as printed books with letters, graphics, etc. printed thereon is arranged in page order to form a booklet, forming a quire, which is then used as the main text. A cover applicator included in a perfect binder, for example, applies adhesive to the spine of the main text to unite the main text with the cover, forming a cover. A process of inserting separate sheets (endpaper sheets) such as frontispieces and endpapers into the quire is also known. In this process, the separate sheets are fixed in a predetermined position relative to the quire by an endpaper applicator before the main text and cover are joined together. The separate sheets with the endpaper sheets fixed in this way form the main text, and the cover applicator attaches the endpaper sheets of the main text to the fore-edge of the cover to unite the main text and the cover.

[0003] Related technology includes a bookbinding device that includes an XY actuator that allows a moving part to move freely in two dimensions, a hand unit that is attached to the moving part of the XY actuator and holds the text, a plurality of binding units that are arranged two-dimensionally within the movable range of the hand unit and perform each process for bookbinding, and a control unit that controls the XY actuator, and based on the control of the control unit, the XY actuator moves the moving part to move the hand unit that holds the text to the required plurality of binding units among the plurality of binding units in a predetermined order, and also moves the hand unit to the position required for performing each process in the binding unit to which it has been moved (see Patent Document 1 below).

[0004] Recently, to improve the efficiency of booklet management, it has become common to attach IC (Integrated Circuit) tags, whose information can be read via wireless communication, to booklets, particularly to the front and back covers. Because IC tags can read information via wireless communication, they can avoid the problem of information becoming unreadable due to poor visibility caused by creases or wrinkles, which can occur when reading conventional barcodes. Therefore, management using IC tags is extremely convenient because it enables quick and reliable reading of booklet information. Such IC tags are attached to booklets and covers manually. Therefore, the attachment process is not performed inline, i.e., integrated into the bookbinding process, but is performed separately, i.e., offline. Consequently, covers with IC tags are prepared in advance, and then the above-mentioned bookbinding process and other processes are carried out to produce booklets with IC-tagged covers.

[Figure 3] FIG. 1 is a schematic perspective view showing a tagging unit according to an embodiment.

[Figure 5] 1 is a flowchart illustrating a tagging method according to an embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a perfect binder incorporating a tagging unit according to the present invention will be described as an example. In this specification and drawings, components having substantially the same functions are designated by the same reference numerals, and redundant description will be omitted.

[0011] (Configuration of perfect binder) 1 is a block diagram showing the configuration of a perfect binder according to this embodiment. The perfect binder 1 performs various binding processes on a main text, which is a bundle of signatures or sheets (e.g., album sheets, printed or unprinted sheets, etc.) collated by a collating machine (not shown), to perfect bind the main text and produce a booklet as a main text with a cover. In this embodiment, inside pages (temporary covers) as separate sheets are attached to the main text so that they are positioned on the front and back sides, and the fore-edge of the cover is attached to these inside pages.

[0012] As shown in FIG. 1, the perfect binding machine 1 includes a text transport unit 10 that transports the text, a processing unit 20 that performs a predetermined binding process, a cover supply unit 30 that sequentially feeds out covers, a tagging unit 40 that attaches an IC tag such as an RFID (Radio Frequency Identification) to the supplied covers, a cover attaching unit 50 that attaches the tagged cover to the text, a discharge unit 60 that discharges the text with the attached cover to, for example, a three-sided trimmer in a subsequent stage, and a control device 70 that drives and controls these various units.

[0013] Below, we will explain the above-mentioned various units and briefly explain the bookbinding process using the perfect binder 1. Figure 2 is a schematic diagram showing the configuration of various units included in the perfect binder according to this embodiment.

[0014] (Text transport unit 10) As shown in FIG. 2, the text transport unit 10 includes a circularly arranged transport chain 110 that forms a round path that circulates horizontally (counterclockwise as indicated by the arrow in the figure). This transport chain 110 is provided with a plurality of clampers (not shown) at predetermined intervals, each of which is configured to be able to grip and release the text A1 using an actuator or the like. The text A1 is raised while being transported to a clamping position by a paper feed riser (not shown), and is gripped by the clampers. The transport chain 110 then moves in one direction to transport the text A1 along the round path. Instead of the transport chain 110, a hand unit with a clamper may be provided, and the text A1 may be gripped by the hand unit. The hand unit may then be moved in three dimensions, including the vertical direction, by combining, for example, a plurality of linear induction motor-type XY actuators, so that the text A1 can be transported.

[0015] (Processing unit 20) The processing unit 20 is disposed on the round path formed by the conveyor chain 110, and performs various binding processes on the text A1 conveyed sequentially by the conveyor chain 110. Specifically, from the upstream side to the downstream side in the conveying direction of the conveyor chain 110, the processing unit 20 is equipped with a milling cutter 210 that cuts the back of the text A1 to align the back, a gully cutter 220 that cuts grooves in the back, a side gluer 230 that applies glue to both sides near the back, and a spine gluer 240 that applies glue to the back. The text A1 conveyed along the round path passes through these devices to be bound, and then is conveyed to the cover attaching unit 50 located downstream.

[0016] (Cover supply unit 30) The cover supply unit 30 is a so-called feeder that is located upstream of the cover attaching unit 50 and supplies covers to the cover attaching unit 50. The cover B sent out by the cover supply unit 30 is placed on a transport conveyor 42 of the tag attaching unit 40, which will be described in detail later.

[0017] (Tag sticking unit 40) The tagging unit 40 is disposed between the cover supply unit 30 and the cover attaching unit 50, and includes a transport conveyor 42 (see FIG. 3) that extends in the return direction of the round path of the transport chain 110 and transports covers in that direction (hereinafter referred to as the cover transport direction). The cover B sent out by the cover supply unit 30 is supplied to the transport conveyor 42, where an IC tag such as an RFID tag is attached, to create a tagged cover B1. The created tagged cover B1 is sent out to the cover attaching unit 50 located downstream. The detailed configuration of the tagging unit 40 will be described later.

[0018] (Cover pasting unit 50) The cover attaching unit 50 extends in approximately one direction up to the vicinity of the junction with the return path of the round path of the conveyor chain 110, and is equipped with a conveyor that transports covers in that direction, and tagged cover B1 is supplied onto this conveyor from the tag attaching unit 40. The tagged cover B1 supplied from the tag attaching unit 40 is transported sequentially to a gluing device, a timing drum, a synchronization section, and a press section. After the press section, the tagged cover B1 and body A1 are transported by the conveyor chain 110 to the edge gluing section.

[0019] Specifically, a gluing device applies edge glue to the left and right edges of the tagged cover B1, a timing drum located where the conveyor joins the return path of the round path synchronizes the feeding timing of the tagged cover B1 with the transport of the main text A1, and a synchronization unit overlaps the spine of the main text A1 with the spine in the center of the tagged cover B1. With the tagged cover B1 overlapped, a press unit presses the tagged cover B1 against the spine and its side edges of the main text A1 to bind them together, and a fore-edge adhesive unit glues the edge of the tagged cover B1 to the inside and back endpapers of the main text A1 with the tagged cover B1 attached to its spine, completing the main text A2 with cover. The main text A2 with cover is then transferred from transport by the transport chain 110 to a transport device (not shown) and transported to the discharge unit 60. The discharge unit 60 may be positioned on the round path, and the body A2 with cover may be transported to the discharge unit 60 by the transport chain 110. Instead of the gluing device, a tape application device may be used that applies double-sided tape to the edge instead of glue.

[0020] (Discharge unit 60) The discharge unit 60 is located downstream of the cover attaching unit 50 and determines the weight of the cover-attached body A2. If the weight is within a predetermined range and the body A2 is determined to be good by the coating amount inspection process described below, the discharge unit 60 transports the cover-attached body A2 to a three-edge trimmer at a downstream stage. The cover-attached body A2 transported to the three-edge trimmer is completed as a bound book by cutting three sides (top, bottom, and fore-edge). The discharge unit 60 also discharges the cover-attached body A2 whose weight is outside the predetermined range or which is determined to be bad by the coating amount inspection process to a path different from the path taken to the three-edge trimmer at a downstream stage.

[0021] (Control device 70) As shown in FIG. 1 , the control device 70 includes a central processing unit (CPU) 710 that primarily controls the control device 70, a random access memory (RAM) 720, a read-only memory (ROM) 730, a storage device 740, and an input / output device 750. The CPU 710 executes the BIOS read from the ROM 730, a non-volatile storage area, the operating system (OS) read from the storage device 740, general-purpose applications, and various other programs by expanding them onto the volatile storage area of ​​the RAM 720. Examples of the programs include programs for driving and controlling various units, such as a program for causing the control device 70 to execute a tagging process (tag affixing method) by the tagging unit 40, which will be described later. The control device 70 loads the various programs to operate the various hardware resources described above in cooperation with each other, thereby controlling the driving of the document transport unit 10, the processing unit 20, the cover supply unit 30, the tagging unit 40, the cover attaching unit 50, and the discharge unit 60. The input / output device 750 is a so-called control panel having, for example, depressible buttons and a display, preferably a touch panel display. The input / output device 750 displays information for the operator to operate each unit and accepts operations from the operator. It also accepts change operations such as changing the settings of each unit as appropriate.

[0022] (Detailed configuration of tagging unit 40) The configuration of the tagging unit 40 according to this embodiment will be described in detail below. Fig. 3 is a schematic perspective view showing the tagging unit according to this embodiment. Fig. 4 is a diagram for explaining the tagging to the cover by the tagging unit according to this embodiment. Note that the symbol X shown in Fig. 3 indicates the cover transport direction in which the cover B is transported.

[0023] As shown in FIGS. 1 and 3, tagging unit 40 includes a transport conveyor 42 extending in the X direction, a labeler 44, and a sensor 46. Transport conveyor 42 is an endless belt formed in a circular shape that is wound around one or a pair of drive rollers (not shown) and moves around to transport objects on the belt, in this case, cover sheet B and tagged cover sheet B1. A cover sheet supply unit 30 is located upstream of transport conveyor 42, and a cover attaching unit 50 is located downstream. Cover sheet B supplied from cover sheet supply unit 30 is placed on transport conveyor 42, and after an IC tag is attached, it is transported to cover attaching unit 50. The drive roller is rotationally driven by a drive device 422 that is controllably connected to control device 70.

[0024] The labeler 44 is located above the transport conveyor 42 and has a cylindrical unwinding shaft 442 around which a strip-shaped roll paper R is wound, with multiple IC tags T aligned in a row and attached to it. In this embodiment, the IC tag T is an RFID tag, and has an IC chip that stores various information such as the booklet's identification information, an antenna for wireless communication connected to the IC chip, a base on which these are placed and held, and a covering layer that covers and protects the IC chip and antenna between the base.

[0025] The unwinding shaft 442 is disposed so that its axis is perpendicular to the cover conveying direction X and the up-down direction, and is rotatably connected by an electric motor (not shown), such as a servo motor, whose drive can be controlled by the control device 70. A recess is preferably provided on the circumferential surface of the unwinding shaft 442 at a position facing the IC chip to prevent contact between the circumferential surface and the IC chip. In this case, the recess may be formed in a ring shape along the circumferential surface of the unwinding shaft 442.

[0026] A peeling roller 444 is disposed downstream and below the unwinding shaft 442 in the cover conveying direction X, close to the upper surface of the conveyor 42. The peeling roller 444 is a so-called free roller disposed so that its axis is perpendicular to the cover conveying direction X and the up-down direction. The peeling roller 444 may be configured to be rotatable by an electric motor such as a servo motor that can be controlled by the control device 70. As with the unwinding shaft 442, it is preferable that a recess be provided on the circumferential surface of the peeling roller 444 at a position facing the IC chip to prevent contact between the circumferential surface and the IC chip. In this case, the recess is formed in a ring shape along the circumferential surface of the peeling roller 444.

[0027] The roll paper R is wound around the peeling roller 444 from the unwinding shaft 442 via one or more guide rollers (not shown), and is then wound around the take-up shaft 446 via one or more guide rollers (not shown). The take-up shaft 446 is located upstream of the unwinding shaft 442 in the cover conveying direction X, with its axis perpendicular to the cover conveying direction X and the up-down direction, and is connected to be rotatable by an electric motor (not shown), such as a servo motor, whose drive can be controlled by the control device 70. Therefore, in this embodiment, the unwinding shaft 442 and the take-up shaft 446 are controlled to rotate in unison by the control device 70, so that the roll paper R can be unwound from the unwinding shaft 442 and taken up by the take-up shaft 446. The unwinding shaft 442 may be configured as a free roller, and only the take-up shaft 446 may be driven and rotated by an electric motor.

[0028] 4, roll paper R is wound around peeling roller 444 from above in cover transport direction X, and then folded back to the upstream side of cover transport direction X. As a result, as roll paper R moves, IC tag T held by roll paper R can protrude from the upper circumferential surface of peeling roller 444 downstream in cover transport direction X, specifically toward cover B. As cover B continues to be transported by transport conveyor 42, the tip of IC tag T comes into contact with cover B, allowing IC tag T to be affixed to cover B. Note that a biasing means such as a roller that biases IC tag T toward cover B may be provided at the position where IC tag T is affixed.

[0029] The diameter of the roll paper R held by the unwinding spindle 442 decreases as the number of IC tags T attached increases, while the diameter of the roll paper R increases after the IC tag T held by the winding spindle 446 is removed. In response to this change in the diameter of the roll paper R, the control device 70 preferably controls the rotation of each shaft so as to individually change the rotation speed and / or rotation angle range of the unwinding spindle 442 and the winding spindle 446. This may be based on detection results from a detection means that detects the rotational position of each shaft, for example, an encoder included in a servo motor that rotates and drives each shaft.

[0030] The labeler 44, including the unwinding shaft 442, peeling roller 444, winding shaft 446, guide rollers (not shown), etc., is configured to be movable along an orthogonal direction perpendicular to the cover conveyance direction X and the up-down direction. Therefore, the labeler 44 can appropriately change the attachment position of the IC tag T in the orthogonal direction relative to the cover B. This change in the orthogonal direction position may be performed automatically by the operator operating the input / output device 750 to input a value indicating the orthogonal direction position, or, of course, may be performed manually.

[0031] The sensor 46 is located above the transport conveyor 42 and upstream of the labeler 44 in the cover transport direction X, and detects the position of the cover B placed on the transport conveyor 42. Specifically, the sensor 46 detects the leading edge of the cover B in the cover transport direction X and sends cover detection information as the detection result to the control device 70. The control device 70 controls the labeler 44 based on the acquired cover detection information and attaches an IC tag T to a predetermined position on the cover B. The sensor 46 may be a contact type, but a non-contact sensor is preferable in consideration of the effect on the cover B. The sensor 46 may be configured as a camera, and the control device 70 may acquire an image obtained by the camera as cover detection information and use image processing to detect the position of the cover B.

[0032] The driving device 422 is an electric motor that drives and rotates the driving roller of the transport conveyor 42, and in this embodiment, a servo motor is used that drives and rotates a rotary shaft for rotating the driving roller based on a pulse signal sent from the control device 70. The driving device 422 has an encoder 424, and the control device 70 adjusts the pulse width of the pulse signal that is sent based on the detection result as a pulse signal from the encoder 424, that is, the rotation amount and / or speed of the rotary shaft.

[0033] (device operation) Next, a description will be given of the tagging process performed by the tagging unit 40. Fig. 5 is a flowchart showing the tagging process according to this embodiment. This process is executed when the power of the perfect binder 1 is turned on and the tagging unit 40 is ready to operate.

[0034] 5, first, the control device 70 sends a pulse signal to rotate the drive roller by the drive device 422, thereby operating the transport conveyor 42 (S101). Thereafter, the control device 70 determines whether cover detection information has been acquired from the sensor 46 (S102). If cover detection information has not been acquired (S102, NO), the control device 70 determines whether cover detection information has been acquired again after a predetermined time (S102). On the other hand, if cover detection information has been acquired (S102, YES), the control device 70 acquires pasting position information pre-stored in the storage device 740 (S103).

[0035] The attachment position information is information for attaching the IC tag T to a predetermined attachment position on the cover B. In this embodiment, the attachment position information is specified as a pulse number threshold, which indicates how many pulses after the cover detection information is acquired, i.e., how many pulses the control device 70 must acquire before driving the labeler 44 to advance the IC tag T toward the cover B. For example, the number of pulses required for the servo motor's rotation shaft to rotate after the cover B has moved a predetermined distance can be calculated and used as the pulse number threshold, with the intention of positioning the area on the cover B where the IC tag T is to be attached in front of the peeling roller 444. Note that the value of the pulse number threshold, i.e., the number of pulses, can be changed as appropriate depending on the size and type of the cover B and the IC tag T, the position of the IC tag T in the cover conveyance direction X relative to the cover B, and other factors. To change the setting, the operator simply inputs a value or the like via the input / output device 750.

[0036] After acquiring the attachment position information, the control device 70 determines whether the current pulse count of the pulse signal, which is the detection result of the encoder 424 acquired since the cover detection information was acquired, has reached the threshold value indicated in the attachment position information (S104). If the current pulse count has not reached the threshold value (S104, NO), the control device 70 proceeds to step S104, where it determines again after a predetermined time whether the current pulse count has reached the threshold value. On the other hand, if the current pulse count has reached the threshold value (S104, YES), the control device 70 drives the labeler 44 to advance the IC tag T onto the cover B (S105). Specifically, the control device 70 drives the unwinding shaft 442 and the winding shaft 446 to rotate, moving the roll paper R and advancing the IC tag T from the peeling roller 444. At this time, the leading edge of the IC tag T comes into contact with the cover B the moment the IC tag T advances, and as the cover B is transported, the IC tag T is sequentially adhered to the cover B from the leading edge to the trailing edge.

[0037] After the IC tag T is advanced, the control device 70 adds 1 to the progress count n to set n to n+1 (S106), and determines whether the preset desired progress count threshold N = progress count n, in other words, whether IC tags T have been affixed to the desired number of cover sheets B (S107). If the progress count threshold N = current progress count n is not met (S107, NO), the process proceeds to step S102, where it is determined again whether cover sheet detection information has been acquired. On the other hand, if the progress count threshold N = current progress count n (S107, YES), the control device 70 determines that IC tags T have been affixed to the desired number of cover sheets B, and the tag affixing process ends.

[0038] According to the present embodiment described above, the process of attaching the IC tag T to the cover B can be incorporated in-line prior to the process of attaching the cover B to the main body A. Therefore, the IC tag T can be attached to the cover B more efficiently than by manual work. Furthermore, based on the cover detection information and the cover attachment position information, the IC tag T can be attached to the desired location on the cover B, such as on front 1, front 2, front 3, or front 4, with high accuracy without positional deviation.

[0039] In this embodiment, it has been described that the tag application unit 40 is incorporated into the perfect binder 1, but this is not limited to this, and it goes without saying that the tag application unit 40 can be incorporated into binding devices other than perfect binders, such as binding devices for saddle-stitched books and caseback books, and the IC tag T can be appropriately attached to the cover.

[0040] In addition, in this embodiment, the IC tag T is attached to the cover B in an unglued state, but this is not limited to this. For example, the gluing device of the cover attaching unit 50 may be located upstream of the tag attaching unit 40, and the IC tag T may be attached to the cover B after gluing.

[0041] Furthermore, in this embodiment, the timing for driving the labeler 44, i.e., the timing for advancing the IC tag T, is described as being based on the number of pulses in the pulse signal detected by the encoder 424 and the pulse count threshold in the cover attachment position information, but this is not limited to this. The labeler 44 may also be driven a predetermined time after the cover detection information is acquired, although this may result in a decrease in the accuracy of the attachment position. Alternatively, the sensor 46 may be located downstream of the labeler 44, and the labeler 44 may be driven immediately after the sensor 46 detects the leading edge of the cover B. In this case, the distance between the labeler 44 and the sensor 46 in the conveyance direction X is important to attach the IC tag T to the desired position on the cover B. To make this distance variable, for example, the labeler 44 and / or the sensor 46 may be configured to be movable in the conveyance direction X manually or automatically (for example, using an actuator such as a linear guide).

[0042] Furthermore, in this embodiment, the tagging unit 40 has been described as having only one labeler 44, but this is not limited to this. When multiple labelers 44 are aligned in the orthogonal direction so that they are positioned at the same position in the cover conveying direction X, each labeler 44 can be driven based on cover detection information from a single sensor 46. On the other hand, when the labelers 44 are aligned in the orthogonal direction but are misaligned in the cover conveying direction X, a sensor 46 can be provided for each of the multiple labelers 44. In this case, the corresponding labeler 44 can be driven based on the cover detection information from each sensor 46. By providing multiple labelers 44 in this way, the tagging unit 40 can affix an IC tag T to each of multiple covers B aligned in the orthogonal direction, thereby achieving further efficiency. It is also possible to affix different types of IC tags T to a single cover B.

[0043] Although the embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. This novel embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as defined in the claims.
