Description

  The present invention relates to a printing system, a printing apparatus, a card conveying apparatus, and a printing method.

  In recent years, not only paper and films but also various materials and shapes have been used as objects to be printed by a printing apparatus such as an ink jet printer. More specifically, for example, printing is performed on a card formed of plastic or the like with an inkjet printer or the like. In this case, in order to appropriately print with high accuracy on a card that is significantly different from paper or the like, it is desirable to perform each operation during printing with a configuration suitable for the card. More specifically, for example, it is desired to perform an operation for conveying a printed card with a configuration suitable for the card.

  Regarding the discharge of the recording medium after printing, for example, the configuration described in Patent Document 1 is known. Patent Document 1 includes a transport unit that transports a recording medium, a recording unit that ejects ink onto the recording medium transported by the transport unit, and a drying unit that dries the ink ejected onto the recording medium. In the inkjet recording apparatus, there is disclosed an inkjet recording apparatus characterized in that after a predetermined time elapses, a discharge unit is provided that can sequentially discharge stock recording media from the storage unit one by one from the lowest position at predetermined intervals. .

  However, as described above, when printing is performed on a card having properties that are significantly different from those of paper or the like, it is desirable to perform an operation of transporting the printed card with a configuration suitable for the card. More specifically, for example, when printing on a card, it is considered that printing is performed by a printing system including a plurality of printing apparatuses instead of using only one printing apparatus (inkjet printer or the like). It is done. In this case, there are a plurality of devices for discharging the printed cards.

  In addition, when printing on cards, it is conceivable to print different contents on each card by printing personal information or the like on the card, for example. In this case, it is desirable to appropriately manage the order of collecting printed cards. As a result, for example, in the case of using a plurality of printing apparatuses, it is conceivable to collect cards printed by the respective printing apparatuses by using a single conveyance path (conveyance line). In this case, for example, it is desirable to appropriately manage the intervals in the transport direction for a plurality of cards transported by the transport path.

  For example, in this case, if the interval between the cards is too tight, there may be a problem in quality control such as exceeding the detection limit of the inspection device. On the other hand, if the distance between the cards is too large, the time required for conveyance becomes long, and there is a possibility that production efficiency (yield per unit time, etc.) is reduced.

  Also, when using a plurality of printing devices, even if the card spacing is fixed in each device, for example, a gap corresponding to the device spacing is generated in the portion between the devices, resulting in uneven card spacing. Is also possible. If such non-uniform spacing occurs, it may be difficult to manage the card.

  Therefore, when printing on a card, it is desired to control the interval between cards to a desired interval (particularly, a constant interval) in the operation of conveying the printed card. SUMMARY An advantage of some aspects of the invention is that it provides a printing system, a printing apparatus, a card transport apparatus, and a printing method that can solve the above-described problems.

  The inventor of the present application has conducted intensive research on a configuration for conveying a printed card. More specifically, as a configuration thereof, in a printing system including a plurality of printing apparatuses, cards after printing in each printing apparatus are arranged in a predetermined position (alignment unit), and then arranged in each printing apparatus. The structure which conveyed the card | curd using the conveyance path | route (conveyance line) of 1 system | strain which connected the part was considered.

  In such a configuration, as the transfer operation by the aligning unit, the operation of the delivery mode in which a plurality of cards are sequentially sent out while setting the interval between the cards, and the card sent from the upstream is relayed and sent downstream. We considered switching between relay operation. In addition, it has been found that in the operation of transporting cards after printing, it is possible to control the spacing between the cards to a desired spacing and transport with a configuration suitable for the cards. In order to solve the above problems, the present invention has the following configuration.

  (Configuration 1) A printing system for printing on a card, which is a part constituting at least a part of a plurality of printing apparatuses and a transport path for transporting a card after printing, and between the plurality of printing apparatuses. Each of the printing apparatuses is a print head that performs printing on the card, and a conveyance path that discharges the card after printing by the print head. The relay unit has a plurality of alignment units and a relay unit by connecting the alignment unit in one printing apparatus and the alignment unit in the other printing apparatus. A transport path for transporting cards in one direction is configured, and the alignment unit in each printing apparatus is a mode in which a plurality of cards are sent to the downstream side of the alignment unit, and the intervals between the plurality of cards are predetermined on the downstream side. Switchable between a delivery mode that transports multiple cards at intervals, and a relay mode that transports cards sent from the upstream side of the alignment unit to the downstream side of the alignment unit in a mode different from the delivery mode Has been.

  When configured in this way, for example, by connecting the alignment units in the respective printing apparatuses via the relay unit, it is possible to appropriately convey the printed cards through one system conveyance path (conveyance line). . Moreover, it can collect | recover collectively in one place about the card printed by the some printing apparatus by this.

  Further, in this case, by causing the alignment unit in each printing apparatus to perform the operation in the sending mode, it is possible to sequentially send out a plurality of cards printed by each printing apparatus at predetermined intervals. . Further, after the cards are sent out, the cards sent from other upstream printing apparatuses can be sent further downstream at arbitrary intervals by causing the alignment unit to perform the operation in the relay mode. Therefore, if comprised in this way, the space | interval between cards can be appropriately controlled to a desired space | interval, for example in the operation | movement which conveys the card | curd after printing. Moreover, thereby, for example, it is possible to appropriately carry with a configuration suitable for a card.

  Moreover, when comprised in this way, a card | curd can be conveyed at a desired speed, for example, without touching a card | curd and stopping the movement of a card | curd mechanically. Therefore, if comprised in this way, a card | curd can be further conveyed at a desired space | interval, for example, without damaging a card | curd.

  In this configuration, the card is, for example, a plate-like body having a quadrangular main surface. As the card, for example, a card made of plastic, cardboard, metal thin plate or the like can be preferably used.

  In this configuration, the alignment unit and the relay unit are, for example, a conveyor device (for example, a belt conveyor device). Further, the relay unit conveys the card at a predetermined constant speed. Further, during the operation in the relay mode, the alignment unit conveys the card at the same speed as the relay unit, for example. Further, during the operation in the delivery mode, the alignment unit conveys the card at a speed different from that of the relay unit. In this case, it is preferable to transport the card at a slower speed than the relay unit.

  Regarding the operation of the alignment unit, the relay mode may be an operation mode executed when another printing apparatus is connected on the upstream side in the transport direction. Therefore, in the printing device on the most upstream side in the transport direction with respect to the printed card among the plurality of printing devices, the alignment unit may execute only the delivery mode. Further, in a printing apparatus other than the most upstream, for example, the alignment unit switches between an operation in the sending mode and an operation in the relay mode as appropriate.

  In this configuration, the printing apparatus functions as a card processing apparatus that discharges a plurality of processed cards. In this case, the card processing in the printing apparatus is printing processing. The printing system may further include, for example, a relay unit that connects any one of the printing apparatuses to an apparatus other than the printing apparatus. More specifically, for example, a relay unit that connects a printing device on the most downstream side in the conveyance direction with respect to the printed card and a card inspection device or a card collection device may be further provided.

  (Configuration 2) In the relay mode, the card is transported at the same speed as that sent from the upstream, and is transported as it is to the downstream side of the rectifying unit. If comprised in this way, a card | curd can be sent to the downstream of an alignment part, for example, without changing the space | interval of a card | curd with a relay part and an alignment part.

  (Configuration 3) The speed at which the alignment unit conveys the card in the relay mode is faster than the speed at which the alignment unit conveys the card in the delivery mode.

  When configured in this way, the alignment unit, for example, sends out the cards to the downstream side with an interval larger than the interval between the plurality of cards arranged in the alignment unit. In this case, for example, the interval at which the card is conveyed becomes larger during operation in the relay mode. Therefore, if comprised in this way, the space | interval which sends a card | curd at the time of the operation | movement in relay mode etc. can be extended appropriately, for example. In addition, the card can be transported while ensuring an appropriate interval between the cards.

  In this case, the interval between the cards in the aligning portion is narrowed until the operation in the delivery mode is executed. Therefore, if constituted in this way, a plurality of cards can be arranged, for example, using the space in the printing apparatus efficiently. This also makes it possible to appropriately increase the production efficiency of the printed card and realize a high yield.

  (Configuration 4) In the delivery mode, the conveyance and the temporary stop are repeated intermittently. With this configuration, for example, when it is desired to increase the interval between cards, after sending out one card, the conveyance of the next card is temporarily stopped to stop the card from moving downstream. The interval between cards can be adjusted freely.

  (Configuration 5) The relay unit is configured to be able to change a distance for transporting a card between a plurality of printing apparatuses. If comprised in this way, it can synchronize more appropriately about the operation timing of a some printing apparatus, for example.

  Here, as described above, when the cards are transported, the interval between the cards is appropriately divided to increase the manufacturing efficiency. However, when using a plurality of printing apparatuses, it is necessary to appropriately synchronize the operation timing of each printing apparatus according to the distance between the apparatuses. Further, in this case, if the synchronization is inappropriate, there is a risk that a gap between the cards will be shifted.

  On the other hand, with such a configuration, by appropriately adjusting the distance of the relay unit, the synchronization of the operations of the plurality of printing apparatuses can be performed without performing complicated control such as timing control of the start of movement of each printing apparatus. Can be adjusted appropriately. Thereby, for example, the interval between cards can be set to a more appropriate distance.

  (Configuration 6) It further includes a stacker unit that drops and stacks cards conveyed by a conveyance path including an alignment unit and a relay unit, and only the end of the card in the conveyance direction is the first in the stacker unit when dropped. The height of the upper surface of the stacked cards is controlled so as to collide with the inner wall of the stacker unit.

  If comprised in this way, it can collect | recover appropriately in a stacker part about the card | curd after printing, for example. In this case, when the card falls on the stacker unit, it is placed on the loaded card from one end edge. Therefore, if comprised in this way, a card | curd can be collect | recovered more appropriately, for example, preventing the rubbing of a printing surface.

  (Configuration 7) A card inspection unit for inspecting a card conveyed by a conveyance path including an alignment unit and a relay unit is further provided, and the card inspection unit excludes a card in which a defect is detected in the inspection. The replacement card is arranged at the removed position, and the replacement card is arranged in place of the removed card, so that the card interval in the conveyance direction is evenly spaced downstream of the card inspection unit in the conveyance direction. To maintain.

  If comprised in this way, it can test | inspect appropriately with respect to the card | curd after printing, for example. In this case, the cards are conveyed at equal intervals in the state before the inspection. Therefore, it is possible to inspect at regular intervals, and it is possible to detect defects more easily. Even after the inspection, if a defective card is eliminated, the replacement card is arranged so that the cards are sent at equal intervals. Therefore, handling of the card becomes easier in the subsequent processing.

  As the replacement card, for example, it is conceivable to use a card of a predetermined color different from a normal card. If comprised in this way, the position which excluded the defective card after collection | recovery of a card | curd can be identified more easily.

  (Structure 8) Each alignment part and relay part convey a card | curd by the belt conveyor system which mounts a card | curd on the rotating belt.

  In the case of such a configuration, for example, at the time of conveyance in the alignment unit and the relay unit, the printed surface of the card is not contacted. Therefore, if comprised in this way, it can convey more appropriately about the card | curd after printing, for example.

  (Configuration 9) The print head is an inkjet head that ejects ink droplets by an inkjet method. If comprised in this way, it can print appropriately with high precision, for example with respect to a card | curd.

  (Configuration 10) The alignment unit is a part on which a single card is placed, and a plurality of individual card conveyances that convey cards at each position in the conveyance direction by being arranged along the card conveyance direction. If the distance between the upstream end and the downstream end in the transport direction in the arrangement of a plurality of individual card transport units is L, and the interval of cards transported on the downstream side of the alignment unit is l, l is smaller than L, and each individual card transport unit can be operated independently of each other by switching between the delivery mode and the relay mode, and at least at some timing, a plurality of individual card transport units in one alignment unit Among the card transport units, some of the individual card transport units on the downstream side operate in the delivery mode, and some of the individual card transport units on the upstream side perform the operation in the relay mode. The interval l may be, for example, an interval that is equal to the interval of cards conveyed by the alignment unit during the relay mode operation.

  If comprised in this way, the space | interval l of the card | curd after sending out by operation | movement of the sending mode can be set more appropriately, for example. In addition, by making it possible to individually switch the operation mode of the individual card transport unit, the card transport speed in each unit of the alignment unit can be set more appropriately.

  (Configuration 11) A printing apparatus that performs printing on a card, and includes a print head that performs printing on the card, and a conveyance path that discharges the card after printing by the print head, and is configured as a preset conveyance. An alignment unit that aligns and aligns a plurality of cards in a direction, and the alignment unit is a mode of sending out a plurality of cards to the downstream side of the alignment unit, and the interval between the plurality of cards is a predetermined interval on the downstream side It is configured to be able to switch between a delivery mode that transports multiple cards and a relay mode that transports cards sent from the upstream side of the alignment unit in a mode different from the delivery mode and transports them downstream of the alignment unit. ing. If comprised in this way, the effect similar to the structure 1 can be acquired, for example.

  (Configuration 12) A card conveying device that conveys a card printed by a printing device, wherein a plurality of cards printed in each of the plurality of printing devices are arranged in a line in a preset conveying direction. An alignment unit and a part constituting at least a part of a conveyance path for conveying a printed card, and a relay unit connecting between the plurality of alignment units. The relay unit includes one alignment unit, another By connecting a plurality of aligning sections, a plurality of aligning sections and a relay section form a transport path for transporting cards in one direction, and each aligning section sends out a plurality of cards to the downstream side of the aligning section. Mode, which is a delivery mode for transporting a plurality of cards so that the spacing between the plurality of cards is a predetermined spacing on the downstream side, and a delivery mode for cards sent from the upstream side of the alignment unit. It is configured to be switchable between a relay mode for conveying in de different modes to the downstream side of the sorting unit. If comprised in this way, the effect similar to the structure 1 can be acquired, for example.

  (Configuration 13) A printing method for printing on a card, wherein a plurality of printing apparatuses are connected by a relay unit that constitutes at least a part of a transport path for transporting a printed card. The device performs printing on a plurality of cards, and each printing device is a print head that performs printing on the card, and a conveyance path that discharges the card after printing by the print head, and a preset conveyance And a relay unit that connects the alignment unit in one printing device and the alignment unit in another printing device to connect the plurality of alignment units and the relay. Are configured to form a transport path for transporting cards in one direction, and the alignment unit in each printing apparatus is a mode in which a plurality of cards are sent to the downstream side of the alignment unit. A delivery mode that transports a plurality of cards so that the card spacing is a predetermined spacing, and a relay mode that transports cards sent from the upstream side of the alignment unit to the downstream side of the alignment unit in a mode different from the delivery mode And can be switched. If comprised in this way, the effect similar to the structure 1 can be acquired, for example.

  According to the present invention, for example, in a printing apparatus that performs printing on cards, the interval between cards can be appropriately controlled to a desired interval. Moreover, thereby, for example, it is possible to appropriately carry with a configuration suitable for a card.

FIGS. 14A to 14D show an example of the operation of the alignment unit 112 in order along the time series.

  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. 1 and 2 show an example of a printing system 10 according to an embodiment of the present invention. FIG. 1 is a photograph showing an example of the configuration of the printing system 10. 1A and 1B show the configuration of the main part of the printing system 10 from different angles. FIG. 2 is a diagram illustrating a simplified configuration of a main part of the printing system 10. In this example, the printing system 10 is a printing system that performs printing on a card, and includes a plurality of printing apparatuses 12, a relay unit 14, a collection unit 16, and a host PC 18. More specifically, in this example, the printing system 10 performs printing on the plastic card 50. The card 50 is, for example, a plate-like body having a quadrangular main surface.

  Each of the plurality of printing apparatuses 12 is an ink jet printer that executes printing on the card 50. The plurality of printing devices 12 are preferably the same inkjet printer. Except as described below, the printing apparatus 12 may have the same or similar characteristics as a known inkjet printer.

  In this example, each printing device 12 includes a card supply unit 102, a transport device 104, a stage 106, a card holding unit 108, a head unit 110, and an alignment unit 112. The card supply unit 102 is a supply unit that supplies the cards 50 before printing one by one. In this example, the card supply unit 102 causes the transfer device 104 to transfer the card by placing one end of the supplied card 50 on the transfer device 104. A more specific configuration and operation of the card supply unit 102 will be described in more detail later.

  The transport device 104 is a transport device that transports the card 50 before printing. As the transport device 104, for example, a belt conveyor device can be suitably used. The transport device 104 transports the cards 50 in the direction indicated by the arrow 32 in the drawing, thereby aligning the plurality of cards 50 in accordance with the way in which the cards 50 are held in the card holding unit 108 later. More specifically, in this example, the transport device 104 sequentially transports the plurality of cards 50 in the horizontal direction with the longitudinal direction of the cards 50 parallel to the transport direction, and arranges them at regular intervals. This also moves the cards 50 in the horizontal direction, and arranges a plurality of cards 50 on the transport device 104 in the same manner as the six cards 50 shown on the stage 106 in the drawing.

  Moreover, as the conveying apparatus 104, the structure which arranged the some belt conveyor can be used suitably, for example. In this case, it is preferable to have individual belt conveyors at positions where the respective cards 50 are to be arranged at the time of alignment. If comprised in this way, the card | curd 50 can be conveyed appropriately and can be aligned, for example.

  The stage 106 is an example of a support unit, and moves a plurality of cards 50 aligned on the transport device 104 to the card holding unit 108. In this case, for example, as shown in the drawing, the stage 106 moves a plurality of cards 50 arranged in the carrying direction of the carrying device 104 to the card holding unit 108 while keeping the arranged state. More specifically, the stage 106 receives a plurality of cards from the transport device 104 by, for example, lifting the plurality of cards 50 arranged on the transport device 104 upward. Then, the plurality of cards 50 are moved to the position of the card holding unit 108 by moving in the direction indicated by the arrow 34 in the drawing. Further, in this example, by inserting a plurality of cards 50 from below the card holding unit 108, the card holding unit 108 holds the plurality of cards 50. In this case, the lower side of the card holding unit 108 is a side opposite to the head unit 110 in the card holding unit 108. Further, when printing is performed, the stage 106 remains below the card holding unit 108 and holds a plurality of cards 50 together with the card holding unit 108. The execution time of printing is, for example, the execution time of an operation for ejecting ink droplets to the card 50.

  In this example, the stage 106 has a suction unit that sucks each of the plurality of cards 50. In each of the above operations, a plurality of cards 50 are sucked at a necessary timing. In addition, after the printing on the card 50 is completed, the stage 106 further moves the plurality of cards 50 to the alignment unit 112. In this case, for example, by moving the plurality of cards 50 held in the card holding unit 108 to the lower side of the card holding unit 108, the plurality of cards 50 are pulled away from the card holding unit 108. Then, the card holding unit 108 further moves in the direction indicated by the arrow 34 and places a plurality of cards 50 on the alignment unit 112.

  The card holding unit 108 is a holding member that holds a plurality of cards 50 when printing is performed. In this example, the printing system 10 holds a plurality of cards 50 at a predetermined printing position facing the head unit 110. A more specific configuration of the card holding unit 108 will be described in more detail later.

  The head unit 110 is a part that executes printing on the card 50. In this example, the head unit 110 includes an inkjet head 202 and an ultraviolet light source 204. The ink jet head 202 is a print head that ejects ink droplets by an ink jet method, and performs a main scanning operation for ejecting ink droplets while moving in a preset main scanning direction (left and right direction in the figure). 50 is printed. In this example, the ink jet head 202 ejects ink droplets of ultraviolet curable ink (UV ink). Then, printing on the card 50 is performed by a multi-pass method in which each position on the card 50 is subjected to main scanning operations a plurality of times. If comprised in this way, it can print appropriately with high precision with respect to the card | curd 50, for example.

  The ultraviolet light source 204 is a light source that emits ultraviolet light that cures the ultraviolet curable ink. The ultraviolet light source 204 irradiates the ink landed on the card 50 with ultraviolet rays by moving together with the inkjet head 202 during the main scanning operation.

  In the modified example of the configuration of the head unit 110, ink other than ultraviolet curable ink may be used. The head unit 110 may have a plurality of inkjet heads 202. In this case, each of the plurality of inkjet heads 202 may eject different colors of ink.

  The alignment unit 112 is a part that aligns the plurality of cards 50 printed by the head unit 110. Further, in this example, the alignment unit 112 aligns the plurality of cards 50 in the preset transport direction by holding the plurality of cards 50 on the upper surface in the same manner as the state placed on the stage 106. This transport direction is a direction indicated by an arrow 36 in the drawing.

  The alignment unit 112 also has a function of a conveyance path for discharging the card 50 after printing by the head unit 110, and constitutes a post-printing conveyance path 20 together with the relay unit 14 and the collection unit 16. The post-printing conveyance path 20 is a one-line conveyance path (conveyance line) for conveying the printed card 50 in one direction. A more specific configuration and operation of the alignment unit 112 will be described in more detail later.

  The relay unit 14 is a transport device that connects the plurality of printing apparatuses 12 and constitutes a part of the post-printing transport path 20. More specifically, in this example, the relay unit 14 connects the alignment unit 112 in one printing apparatus 12 and the alignment unit 112 in another printing apparatus 12. The collection unit 16 is a part that collects the printed card 50 and is further connected to the downstream side of the alignment unit 112 of the printing apparatus 12 on the downstream side in the conveyance direction in the post-printing conveyance path 20. Specific configurations and operations of the relay unit 14 and the collection unit 16 will be described in more detail later together with the alignment unit 112.

  The host PC 18 is a computer that controls the operation of the printing system 10. The host PC 18 controls the operation of printing on a plurality of cards 50 by controlling the operation of each unit of the printing system 10. For example, the host PC 18 preferably manages the number of cards 50 to be printed, the number of printed cards 50, the number of defective cards 50, and the like. With the above configuration, in this example, the printing system 10 performs printing on a plurality of cards 50.

  In FIG. 2, for convenience of explanation, the configuration of each part is shown in a simplified manner. Therefore, the actual configuration of the printing system 10 is not limited to the illustrated configuration, and various modifications can be made. For example, the lengths of the relay unit 14 and the collection unit 16 may be longer than the alignment unit 112 in each printing apparatus 12. The printing system 10 may include three or more printing apparatuses 12. In this case, for example, the respective printing apparatuses 12 are connected by the relay unit 14. The printing system 10 may further include a configuration other than that described above.

  In the printing system 10 of this example, it is conceivable to print individual contents for each of the plurality of cards 50. More specifically, for example, the contents including individual personal information may be printed on each card 50. Next, the configuration and operation of each unit of the printing system 10 will be described in more detail.

FIG. 3 and 4 show an example of a more specific configuration of the card supply unit 102. FIG. FIG. 3 is a photograph showing an example of the configuration of the card supply unit 102. FIG. 3A shows an example of the overall state of the card supply unit 102. FIG. 3B is a diagram showing an example of the state of the main part of the card supply unit 102, and shows an example of the state near the suction cup, which will be described later. FIG. 4 is a diagram showing a simplified configuration of the main part of the card supply unit 102. In this example, the card supply unit 102 includes a card storage unit 302, an intermediate storage unit 304, an upper storage unit 306, a support unit 308, a suction cup 310, a protrusion prevention plate 312, a charge removal unit 314, a stopper 320, and a stopper 322.

  The card accommodating portion 302, the intermediate accommodating portion 304, and the upper accommodating portion 306 are portions that respectively accommodate a plurality of cards 50, and are provided in this order from the lower side in the gravity direction. The card accommodating portion 302, the intermediate accommodating portion 304, and the upper accommodating portion 306 may be portions obtained by dividing one cylindrical body. In addition, it is preferable that predetermined intervals are provided between the card storage unit 302 and the intermediate storage unit 304 and between the intermediate storage unit 304 and the upper storage unit 306, respectively.

  More specifically, in this example, the card storage unit 302 is a portion (magazine unit) that supplies the card 50 in the card supply unit 102, and as shown in the drawing, a plurality of cards 50 before printing are stored. It is stacked and accommodated in the vertical direction. The intermediate accommodating portion 304 is a portion (pool portion) that accommodates the plurality of cards 50 above the card accommodating portion 302, and accommodates the plurality of cards 50 before printing stacked in the vertical direction. The intermediate storage unit 304 supplies the plurality of cards 50 to the card storage unit 302 by dropping the plurality of cards 50 stored at a predetermined timing. Accordingly, when the card 50 is moved from the intermediate accommodation unit 304 to the card accommodation unit 302, the intermediate accommodation unit 304 moves, for example, all the accommodated cards 50 to the card accommodation unit 302. In this example, the number of cards 50 that can be accommodated in the intermediate accommodating portion 304 is smaller than the number of cards 50 that can be accommodated in the upper accommodating portion 306.

  The upper accommodating portion 306 is a portion that accommodates the plurality of cards 50 above the intermediate accommodating portion 304, and accommodates the plurality of cards 50 before printing stacked in the vertical direction. Then, the upper storage unit 306 drops a plurality of cards 50 stored in a certain range close to the intermediate storage unit 304 at a predetermined timing to the intermediate storage unit 304 by dropping a plurality of cards. The card 50 is supplied. As a result, when the card 50 is moved from the upper storage unit 306 to the intermediate storage unit 304 in a state where a sufficient number of cards 50 are held in the upper storage unit 306, the upper storage unit 306 stores, for example, Among the existing cards 50, some of the cards 50 are moved to the intermediate storage unit 304.

  The support means 308 is a non-moving support means provided in the card accommodation unit 302, and the lowest card among the plurality of cards 50 stacked in the vertical direction in the card accommodation unit 302 is the lowest card 50. One edge and the other edge of the card 50 are supported. More specifically, in this example, the one and other edges of the card 50 are, for example, one and the other edges in the longitudinal direction of the card 50.

  Note that the support means 308 may be, for example, a convex body that is installed or formed on the wall surface of the card housing portion 302. Further, the support means 308 supports the lowermost card 50 with such a strength that, for example, the lowermost card 50 is peeled off by suction by the suction cup 310.

  The suction cup 310 is a suction unit that sucks the lowest card 50, sucks the lowest card 50 supported by the support unit 308, and pulls the lowest card 50 by pulling downward. Further, the suction cup 310 picks up the lowest card 50 and takes out the lowest card 50 by bending the card 50 downward. Then, at least one end of the removed card 50 is placed on the transport device 104. As a result, the card 50 supplied from the card supply unit 102 is transported by the transport device 104 as described with reference to FIG. The suction operation by the suction cup 310 will be described in more detail later.

  The protrusion preventing plate 312 is a plate-like body for preventing unnecessary protrusion of the card 50 from the card accommodating portion 302. In this example, the protrusion prevention plate 312 extends downward to the vicinity of the transport device 104 on the card 50 moving direction side in the card storage portion 302. In this case, the movement direction side of the card 50 in the card accommodation unit 302 is a movement direction side in which the card 50 supplied from the card accommodation unit 302 is conveyed by the conveyance device 104. With this configuration, the protrusion prevention plate 312 prevents, for example, the card 50 from protruding from the card storage portion 302 toward the moving direction side of the card 50.

  Here, when the card 50 is peeled off by bending as in this example, an unexpected behavior may be exhibited when the card 50 returns from the bent state to the original state. On the other hand, according to this example, by using the protrusion prevention plate 312, for example, the card 50 can be appropriately prevented from protruding to the transport device 104 or the like. Thereby, for example, the card 50 can be more appropriately placed at a desired position in the transport device 104.

  The static eliminating unit 314 is a unit that removes static electricity charged in the stacked cards 50. In this example, the static elimination means 314 removes static electricity by spraying a gas that eliminates static electricity toward at least a position where the suction cup 310 attracts the card 50. If comprised in this way, the influence of static electricity can be reduced appropriately, for example. Thereby, for example, it is possible to appropriately prevent the card 50 that has been peeled off due to the influence of static electricity from returning to the original direction.

  The gas for removing static electricity is, for example, air containing predetermined ions. For example, a known ion generator can be suitably used as the static elimination unit 314.

  The stopper 320 is a member that supports the plurality of cards 50 accommodated in the intermediate accommodating portion 304, and is stacked in the intermediate accommodating portion 304 by projecting downward from the card 50 at the lower portion of the intermediate accommodating portion 304. A plurality of cards 50 are supported from below. Further, the stopper 320 can be retracted to the outside of the lower surface of the card 50, and the card 50 in the intermediate accommodating portion 304 is not supported by retracting at a predetermined timing. Accordingly, the stopper 320 drops the plurality of cards 50 in the intermediate storage unit 304 to the card storage unit 302. If comprised in this way, supply of the card | curd 50 from the intermediate | middle accommodating part 304 to the card | curd accommodating part 302 can be performed appropriately, for example.

  The stopper 322 is a member that supports the plurality of cards 50 accommodated in the upper accommodating portion 306, and presses the side surface of the card 50 accommodated in the lower portion of the upper accommodating portion 306, thereby A plurality of cards 50 stacked in 306 are supported. As the stopper 322, for example, a silicone rubber member or the like can be suitably used.

  Moreover, the stopper 322 can adjust the pressure which presses the side surface of the card | curd 50, and will be in the state which does not support the card | curd 50 in the upper accommodating part 306 by weakening a pressure in a predetermined timing. Accordingly, the stopper 322 causes the plurality of cards 50 in the upper storage unit 306 to drop into the intermediate storage unit 304. If comprised in this way, supply of the card | curd 50 from the upper accommodating part 306 to the intermediate | middle accommodating part 304 can be performed appropriately, for example.

  With the above configuration, according to this example, the card supply unit 102 can appropriately supply the card 50 before printing. Subsequently, the suction operation by the suction cup 310 will be described in more detail.

  FIG. 5 shows an example of the suction operation by the suction cup 310. FIG. 5A is a photograph showing an example of the moment when the suction cup 310 is attracted to the card 50. FIGS. 5B and 5C are diagrams illustrating an example of the suction position of the suction cup 310 and the suction operation.

  In this example, the suction cup 310 is attracted to the lower surface of the card 50 at the offset position shifted in any direction from the center of the card 50, not at the center of the card 50. In this case, the offset position is a position shifted in either direction from the center of the card located between one and the other edges of the card 50. In this example, the offset position is a position shifted to the downstream side in the transport direction by the transport device 104. Further, the downstream side in the transport direction by the transport device 104 is the moving direction side of the card 50 by the transport device 104.

  More specifically, in this example, the card supply unit 102 supplies the card 50 to the transport device 104 so that the longitudinal direction of the card 50 and the transport direction are parallel to each other. In this case, as shown in FIGS. 5B and 5C, the suction position of the suction cup 310 is shifted from the center in the longitudinal direction of the card 50 to the downstream side in the transport direction by the transport device 104. become. In this case, it is preferable that the suction position is not shifted in the width direction of the card 50 orthogonal to the longitudinal direction. More specifically, the offset position is preferably a distance that is 10% or more of the length in the longitudinal direction of the card 50 with respect to the amount of slip at the suction position, for example. The amount of displacement of the suction position is, for example, the distance between the center of the card 50 and the suction center position of the suction cup 310.

  If constituted in this way, for example, since the card 50 is taken out in a state inclined to the side corresponding to the offset position, it is appropriately prevented that the orientation of the card 50 is not fixed when the card 50 is supplied. be able to. More specifically, in this example, the card 50 is supplied in a state where the leading side of the card 50 in the moving direction is inclined by setting the offset position in accordance with the moving direction of the card 50 by the transport device 104. Will do. In this case, since the card is peeled off from the carry-out side connected to the transfer device 104, the card 50 can be carried out more stably and reliably. In addition, this makes it possible to carry out the card to the transport device 104 more smoothly.

  Furthermore, in this case, the card 50 peeled off by the suction cup 310 adsorbed at the offset position is always brought into contact with the transport device 104 first with one edge directed downward. In this case, the end edge is pulled in the moving direction, so that a trouble such as a card being caught in the card accommodating portion 302 is less likely to occur. Therefore, according to this example, for example, the card 50 can be supplied more smoothly.

  In addition, for example, when the center of the card 50 in the longitudinal direction is sucked and peeled off, it is conceivable that the bending of the card 50 is increased. As a result, the stability of peeling may be reduced. On the other hand, according to the present example, for example, the bending of the card 50 can be more appropriately suppressed. Thereby, supply of card 50 can be performed more stably.

  Further, in this example, the card 50 can be supplied more appropriately by using a configuration in which the card accommodation unit 302, the intermediate accommodation unit 304, and the upper accommodation unit 306 are separated. More specifically, for example, when a plurality of cards 50 are stacked, the entire load of the stacked cards 50 is applied to the lowermost card 50. For this reason, for example, when the cards 50 are peeled off by the suction cup 310, if the number of stacked cards 50 is too large, it may be difficult to peel the cards 50 one by one.

  In contrast, in this example, for example, by sequentially moving the cards 50 from the upper storage unit 306 to the card storage unit 302 via the intermediate storage unit 304, the number of cards 50 stored in the card storage unit 302 is appropriately set. Can be reduced. Thereby, peeling of the card | curd 50 by the suction cup 310 can be performed more reliably.

  Further, in this case, by providing the upper storage portion 306, the intermediate storage portion 304, and the card storage portion 302 in order from the top in the direction of gravity, as described above, the card can be easily used using gravity. 50 can be moved. Further, instead of moving the card 50 directly from the upper accommodating portion 306 to the card accommodating portion 302, for example, a predetermined number of cards to be moved to the card accommodating portion 302 next by sandwiching the intermediate accommodating portion 304 therebetween. Can be prepared in the intermediate accommodating portion 304 in advance. Therefore, according to this example, for example, the card can be quickly and reliably moved to the card storage unit 302.

  Further, in this case, for example, when the cards 50 are separated when falling from the upper storage unit 306 to the intermediate storage unit 304, the degree of sticking between the cards 50 can be reduced. Therefore, according to this example, also in this respect, the card 50 can be peeled off more easily in the card accommodating portion 302.

  Further, in FIG. 4 and the like, for convenience of illustration, the configuration of each part of the card supply unit 102 is simplified. However, in an actual configuration, it is preferable that specific configurations of the card storage unit 302, the intermediate storage unit 304, the upper storage unit 306, and the like are more suitable for holding a plurality of cards 50. More specifically, for example, in the card accommodating portion 302, it is preferable that at least a portion where the card 50 is supported by the support means 308 is formed in an inverted C shape. In this case, the portion where the card 50 is supported by the support means 308 is in the vicinity of the position where the support means 308 is provided. In addition, being formed in an inverted square shape means that, for example, two opposing surfaces (wall surfaces) are formed so that the width gradually decreases toward the bottom.

  If comprised in this way, the card | curd 50 can be hold | gripped more reliably, for example irrespective of the variation in the magnitude | size of the card | curd 50, or the residual amount. Moreover, it is preferable that the intermediate storage portion 304 and the upper storage portion 306 are also formed in an inverted C shape at least at a portion where the card 50 is supported.

  Next, in connection with the configuration of the card supply unit 102, an example of a more specific configuration of the transport device 104 that transports the card 50 supplied from the card supply unit 102 will be described. 6 and 7 show an example of the configuration of the transport device 104. FIG. FIG. 6 shows an example of the configuration of the double feed detection sensor 330 provided in the transport apparatus 104.

  In this example, the transport device 104 further includes a double feed detection sensor 330 in addition to the configuration for transporting the card 50. The double feed detection sensor 330 is a sensor that detects an abnormality when two or more cards 50 are supplied in a superimposed manner from the card supply unit 102. Further, the double feed detection sensor 330 is provided in the transport device 104, thereby being provided in the transport path of the card 50 from the card supply unit 102 to the head unit 110. With this configuration, for example, it is possible to prevent a two-sheet feeding error in which two cards are stacked and carried out.

  FIG. 7 is a photograph showing an example of how the card 50 is transported by the transport device 104. FIGS. 7A and 7B show an example of a state in which the transport device 104 is viewed from different angles. As shown in the figure, in this example, the transport device 104 sequentially transports a plurality of cards 50 supplied from the card supply unit 102. Further, the plurality of conveyed cards 50 are arranged at positions accessible from the stage 106.

  Next, a more specific configuration of the card holding unit 108 will be described. 8 and 9 show examples of specific configurations of the card holding unit 108. FIG. FIG. 8 is a photograph and a design drawing showing an example of the configuration of the card holding unit 108. FIG. 8A shows a photograph of the card holding unit 108. FIG. 8B is a diagram showing a design drawing of the card holding unit 108 shown in the photograph in FIG. 8A, and shows a top view and a cross-sectional view of the card holding unit 108. In FIG. 8B, the dimensions described in the figure are an example of the dimensions of the card holding unit 108. FIG. 9 shows a simplified configuration of the main part of the card holding unit 108. FIG. 9A is a top view showing a portion of the card holding unit 108 that holds one card. FIG. 9B is a cross-sectional view corresponding to the portion shown in FIG.

  As described with reference to FIG. 2 and the like, the card holding unit 108 holds a plurality of cards 50 (see FIG. 2) carried by the stage 106 (see FIG. 2) side by side. More specifically, in the illustrated case, the card holding unit 108 holds six cards 50 side by side along a region through which the head unit 110 (see FIG. 2) passes in the main scanning operation.

  In this example, the card holding unit 108 includes a punching die part 402, a plurality of urging means 404, and a plurality of deterring parts 406. The punching die 402 is a plate-like body in which a through hole 410 having substantially the same shape as the card 50 to be held is formed. In this example, six through holes 410 corresponding to the number of cards 50 to be held at the same time are formed side by side in the die part 402. Further, the through-hole 410 of the die part 402 is formed to be slightly larger than the card 50 so that the card 50 to be held can be inserted. About the through-hole 410, being substantially the same shape as the card 50 is, for example, a size that allows the insertion of the card 50 and a shape that is substantially the same as the card 50 as long as the object of holding the card 50 can be achieved. It is to be. Specifically, it can be said that a size that is substantially the same as the card 50 and slightly larger is preferable.

  The plurality of urging means 404 are configured to urge the card 50 in the through hole 410, and press the outer peripheral edge of the card 50 against the inner wall as a face in the punching die part 402 at the printing position. In this case, the test face is, for example, a surface for alignment. Further, in this example, the inner wall as a test face in the punching die part 402 is, for example, at least two surfaces adjacent to each other on the inner wall of the punching die part 402. In this case, for example, the urging unit 404 presses the outer peripheral edge of the card 50 against at least two adjacent sides of the inner wall of the punching die 402 at the printing position. In this example, the urging means 404 is a plate-like spring material (plate spring), and is attached to the inner wall of the punching die part 402. If comprised in this way, the biasing means 404 can be appropriately provided with a simple structure, for example. Further, the biasing means 404 is provided at the position of two adjacent sides in each through-hole 410 and presses the card 50 toward the opposite sides.

  When configured in this manner, of the sides of the inner wall of the punching die 402, the side against which the outer peripheral edge of the card 50 is pressed functions as a reference reference side. In this case, the side of the inner wall of the die part 402 may be the side of the opening of the die part 402. In practice, the side of the inner wall of the punching die 402 may be, for example, a region where the side surface of the card 50 contacts. If comprised in this way, the position of the card | curd 50 can be appropriately matched with a desired position with high precision by pressing the outer periphery of the card | curd 50 against the edge | side of the inner wall of the die part 402 by the biasing means 404, for example. it can.

  The plurality of restraining portions 406 are members for restraining the card 50 from moving further in the forward direction from the printing position, and are provided at the opening on the head portion 110 side in the through hole 410 of the punching die portion 402. When the card 50 moves to the positive direction side more than necessary, it is provided on at least two adjacent sides in the punching die 402 so as to contact a part of the card 50 from the positive direction side. These two sides are the sides of the surface to be a test face in the punching die part 402 and are adjacent to each other in the opening of the through hole 410. In this case, the positive direction side is, for example, a direction from one opening into which the card 50 is inserted into the other opening in the through hole 410 of the punching die 402. In other words, the positive direction may be, for example, a direction from the print position where the card 50 is to be held in the card holding unit 108 toward the head unit 110. Thereby, the plurality of deterring portions 406 deter the card 50 inserted from one opening in the through hole 410 from coming out of the other opening.

  Moreover, in this example, the suppression part 406 is further provided also in sides other than two adjacent sides in the inner wall of the die part 402, for example. More specifically, in the illustrated case, the restraining portions 406 are claw-like portions formed on the sides of the inner wall of the punching die portion 402, and two each are provided on each of the four sides surrounding the through-hole 410. It has been. Further, the respective restraining portions 406 are arranged on the side of the punching die 402 facing the head portion 110, so that when the card 50 moves more than necessary in the forward direction side, from the head portion 110 side. Hold a part of the card. If comprised in this way, it can suppress appropriately that the card | curd 50 moves more than necessary from the printing position to the positive direction in the position of each edge | side, for example.

  Further, with respect to such a card holding portion 108, the stage 106 inserts the card 50 from one opening portion of the through hole 410 while supporting the plurality of cards 50, and moves the card 50 in the forward direction within the punching die portion 402. Thus, a plurality of cards 50 are installed at the printing position. Further, the ink jet head 202 (see FIG. 2) in the head portion 110 is fitted into the die portion 402 and is exposed to the surface of the card 50 that is exposed while pressed against the face of the die portion 402 at the printing position. Print. In addition, after the printing by the inkjet head 202 is completed, the stage 106 moves the plurality of cards 50 in the reverse direction (downward) from the printing position and takes them out of the card holding unit 108, and further, the alignment unit 112 (see FIG. 2). Move to.

  In such a configuration, for example, by moving the card 50 in the forward direction by the stage 106 in the punching die 402, the card 50 can be properly aligned without complicated adjustments. it can. Furthermore, by providing the suppression unit 406, it is possible to prevent the card 50 from moving forward in the forward direction more than necessary and protruding from the punching die unit 402. Therefore, according to this example, for example, it is possible to appropriately prevent the positional deviation of the card 50. In addition, this enables reliable printing at a desired position during printing.

  Further, in the case of the configuration as in this example, even when the card 50 is warped by the configuration in which the card 50 is pressed by the restraining unit 406 while being biased by the biasing means 404, for example, the warpage of the card 50 is also generated. Etc. can be corrected and the card 50 can be appropriately installed at the printing position. Therefore, according to this example, for example, printing on a card can be performed more easily and reliably. Further, in this case, the card 50 inserted into the through hole 410 of the punching die part 402 is supported by the stage 106 from one side and provided with a restraining part 406 on the other side, so that the card 50 is sandwiched from above and below. The card 50 can be securely held.

  Here, as described above, in this example, the card 50 is inserted in the movement in the positive direction S with respect to the punching die 402 by the stage 106. Therefore, it is preferable that the urging unit 404 is configured so that the urging force with respect to the card 50 inserted into the punching die unit 402 increases as it goes in the positive direction. If comprised in this way, the card | curd 50 can be inserted more smoothly, for example. Further, by increasing the urging force toward the positive direction S, for example, the urging force can be more reliably expressed at the printing position.

  In addition, as shown in the cross-sectional view of FIG. 9B, in this example, the punching die part 402 has a structure that is divided into a plurality of members (guide part 414 and frame body 412) in the vertical direction. More specifically, in the illustrated case, the punching die part 402 includes a guide part 414 that is a part into which the card 50 is introduced, and a frame body 412 in which a suppressing part 406 is provided. Further, the frame body 412 is overlapped with the guide portion 414 on the positive direction side.

  In the case of such a configuration, for example, each of the guide portion 414 and the frame body 412 can be separately provided according to the required accuracy, so that the formation can be facilitated. More specifically, for example, the shape of the guide portion 414 is relatively simple, whereas the shape of the frame body 412 is more complicated by including the suppression portion 406 and the like. In this case, if both are to be formed with the same accuracy, high-precision processing is performed also on the portion of the guide portion 414 having a simple shape, resulting in an increase in labor and an increase in manufacturing cost. May occur.

  On the other hand, according to the present example, as described above, each of the guide portion 414 and the frame body 412 can be appropriately formed with the accuracy required. Thereby, the die part 402 can be formed more easily.

  In addition, as described with reference to FIG. 2 and the like, in this example, the stage 106 includes a suction unit. In this case, in the operation of holding the card 50 by the card holding unit 108, it is preferable to perform the suction after aligning the position of the card 50. More specifically, for example, in the operation of installing the card 50 at the printing position, it is preferable that the stage 106 inserts the card into the die part without performing suction by the suction means. In this case, it is preferable that the card is sucked by the suction means after the card 50 reaches the printing position.

  In such a configuration, for example, since the position of the card 50 is not fixed by the suction unit until the card 50 reaches the printing position, the biasing unit 404 or the like receives interference from the suction unit. The position of the card 50 can be appropriately corrected. This also makes it possible to appropriately align the position of the card 50 with high accuracy. And after the card | curd 50 arrives at a printing position, a card | curd can be hold | maintained more reliably by adsorb | sucking with an adsorption | suction means. Therefore, if comprised in this way, the card | curd 50 can be hold | maintained more reliably with higher precision, for example. This also makes it possible to print the print position and the like more reliably with high accuracy.

  In this example, for example, it can be said that the use of the suppression unit 406 enables such adsorption timing control. That is, for example, when the restraining unit 406 is not used, if the card 50 is inserted into the punching die unit 402 without being attracted, the card 50 pops out due to the biasing force of the biasing means 404 and the like, and the position of the card 50 is set appropriately. It will be difficult to meet this. On the other hand, in this example, by using the suppression unit 406, the card 50 can be inserted into the punching die unit 402 and properly positioned even when it is not attracted.

  Moreover, as the suppression part 406, using the structure of the shape which protrudes slightly from the upper surface of the punching die part 402 etc. can be considered, for example. On the other hand, when the inkjet head 202 is used as in this example, printing can be performed in a non-contact state on a printing target. For this reason, for example, even when the suppression unit 406 having a shape protruding from the upper surface of the punching die unit 402 is used, the printing operation is hardly hindered. Therefore, according to this example, the suppression unit 406 can be used more appropriately by combination with the inkjet head 202.

  Subsequently, a specific configuration and operation of the post-printing conveyance path 20 including the alignment unit 112 and the like will be described in more detail. 10 to 13 show an example of a specific configuration and operation of the post-printing conveyance path 20. FIG. 10 is a photograph showing an example of the configuration of the post-printing conveyance path 20. FIG. 10A is a photograph showing an example of the overall appearance of the post-printing conveyance path 20, and shows an example of the appearance of the back side of the printing apparatus 12. The back side of the printing apparatus 12 is the side where the alignment unit 112 (see FIG. 2) is provided in the printing apparatus 12. FIG. 10B is a photograph showing the vicinity of the alignment unit 112 in the post-printing conveyance path 20 in more detail.

  FIG. 11 shows a simplified configuration of a main part of the post-printing conveyance path 20. FIG. 11A shows an example of the overall configuration of the post-printing conveyance path 20. FIG. 11B shows an example of the configuration of the alignment unit 112. FIG. 12 is a photograph showing an example of how the card 50 is transported by the post-printing transport path 20. FIG. 12A is a photograph showing a state in which the post-printing conveyance path 20 conveys the card 50 from the upstream side in the conveyance direction. FIG. 12B is a photograph showing the state of the post-printing conveyance path 20 from the downstream side in the conveyance direction.

  As described with reference to FIG. 2 and the like, in this example, the post-printing conveyance path 20 includes a plurality of alignment units 112, a relay unit 14, and a collection unit 16. Among these, each of the plurality of alignment units 112 is a portion where a plurality of cards 50 (see FIG. 2) printed by the corresponding printing device 12 are arranged. The relay unit 14 is a transport device that connects the plurality of printing devices 12, and connects the plurality of alignment units 112.

  The collection unit 16 is a part that collects the printed card 50 and is provided further downstream of the downstream alignment unit 112. In this example, the collection unit 16 includes a transport device 42, a card inspection unit 44, and a stacker unit 46. The transport device 42 is a transport device that transports the card 50 from the downstream alignment unit 112 to the stacker unit 46. The transport device 42 may have the same or similar function and configuration as the relay unit 14 except for the devices connected to both ends. Further, the conveying device 42 can be considered as a relay unit that connects the printing device 12 and another device. The card inspection unit 44 is an inspection device that inspects the conveyed card 50. The stacker unit 46 is a collection device that collects the cards 50 conveyed by the conveyance path 20 after printing. The card inspection unit 44 and the stacker unit 46 will be described in more detail later.

  Here, in this example, the conveying device 42 in the plurality of aligning units 112, the relay unit 14, and the collecting unit 16 conveys the cards by a belt conveyor system in which the cards are placed on a rotating belt. When comprised in this way, at the time of conveyance in each part, for example, it does not contact the surface on which the card 50 was printed. Therefore, if comprised in this way, the card | curd 50 after printing can be conveyed more appropriately, for example.

  Further, in this example, for example, by connecting the alignment unit 112 in each printing apparatus 12 via the relay unit 14, the post-printing conveyance path 20, which is a single conveyance line, for the printed card 50. And can be transported appropriately. This also allows the cards 50 printed by the plurality of printing devices 12 to be collected in one place. For example, if a transport path of a separate system from the alignment unit 112 is provided, the apparatus may be increased in size and the mechanism may be complicated.

  Further, regarding the transport speed, the transport device 42 in the relay unit 14 and the collection unit 16 transports the card 50 at a predetermined constant speed. In this case, the relay unit 14 and the transport device 42 transport the card 50 at the same speed. On the other hand, each of the plurality of alignment units 112 is configured to be able to execute a plurality of types of operations with different ways of carrying the card 50 by switching a plurality of operation modes.

  More specifically, in this example, each alignment unit 112 is configured to be able to switch between a delivery mode and a relay mode as an operation for transporting the card 50. In this case, the delivery mode is a mode in which a plurality of cards 50 printed by the printing apparatus 12 provided with the alignment unit 112 are sent to the downstream side of the alignment unit 112. When executing the delivery mode, the aligning unit 112 conveys the plurality of cards 50 by setting the conveyance speed so that the intervals between the plurality of cards 50 become a predetermined interval on the downstream side. In this case, the alignment unit 112 adjusts the interval of the cards 50 to a desired interval by transferring the cards 50 at a speed different from the transfer speed by the relay unit 14. More specifically, in this example, the alignment unit 112 conveys cards at a slower speed than the relay unit 14 when the delivery mode is executed. Then, the interval between the cards 50 in the relay unit 14 is larger than the interval between the cards 50 in the alignment unit 12. Conversely, by increasing the speed of the alignment unit 12 as compared with the relay unit 14, the interval between the cards 50 can be reduced.

  The relay mode is an operation mode in which the card 50 sent from the upstream side of the alignment unit 112 is conveyed in a mode different from the delivery mode and conveyed to the downstream side of the alignment unit 112. In this case, since the alignment unit 112 serves as a buffer portion, it is possible to freely adjust the card interval by changing the speed of the relay mode or the like. The card 50 sent from the upstream side of the alignment unit 112 is a card 50 sent via the relay unit 14. Therefore, for example, if the card 50 is transported at the same speed as the sent speed, the card 50 is transported at the same speed as the relay unit 14, so that the card is transported at the same interval in the relay unit 14 and the alignment unit 112. . In this case, the speed at which the alignment unit 112 transports the card 50 in the relay mode is faster than the speed at which the alignment unit 112 transports the card 50 in the delivery mode.

  Regarding the operation of the alignment unit 112, the relay mode may be an operation mode executed when another printing apparatus 12 is connected on the upstream side in the transport direction. Therefore, in the printing device 12 that is on the most upstream side in the post-printing conveyance path 20 among the plurality of printing devices 12, the alignment unit 112 may execute only the delivery mode. Moreover, in the printing apparatuses 12 other than the most upstream, the alignment unit 112 executes, for example, appropriately switching between the operation in the sending mode and the operation in the relay mode.

  When configured in this way, for example, by causing the alignment unit 112 in each printing device 12 to perform an operation in the sending mode, a plurality of cards 50 printed by each printing device 12 are set in advance. It can be sent out sequentially at regular intervals. Further, after the card 50 is sent out, the sorting unit 112 is operated in the relay mode so that the card 50 sent from the other upstream printing device 12 is sent further downstream with the interval maintained. Can do. Therefore, according to this example, for example, in the operation of transporting the printed cards 50, the interval between the cards 50 is appropriately controlled to a desired interval, for example, the control is performed such that all the cards 50 are constant intervals. Can do. Moreover, thereby, for example, it is possible to appropriately carry with a configuration suitable for the card 50.

  Further, in this case, the alignment unit 112 performs the operation in the delivery mode so that the interval is made larger than the interval between the plurality of cards 50 arranged in the alignment unit 112 immediately after printing by the printing apparatus 12, and the downstream side The card will be sent out. As a result, for example, the interval at which the card 50 is conveyed during the operation in the relay mode becomes larger. Therefore, according to the present example, for example, the interval for sending the card 50 can be appropriately increased during operation in the relay mode. Thereby, the card | curd 50 can be conveyed, ensuring the space | interval of the card | curd 50 appropriately.

  In this case, the interval between the cards 50 in the alignment unit 112 is narrowed until the operation in the delivery mode is executed. Therefore, if comprised in this way, the several card | curd 50 can be put in order, for example using the space in the printing apparatus 12 efficiently. This also makes it possible to appropriately increase the manufacturing efficiency of the printed card 50 and realize a high yield.

  Moreover, when comprised in this way, the card | curd 50 can be conveyed at a desired speed, for example, without contacting the card | curd 50 and stopping the movement of the card | curd 50 mechanically. Therefore, if comprised in this way, the card | curd 50 can be conveyed by a desired space | interval, for example, without damaging the card | curd 50. FIG.

  As for the configuration of the alignment unit 112, more specifically, for example, a configuration in which a plurality of belt conveyors 502 are arranged as shown in FIG. Each of the plurality of belt conveyors 502 has a configuration in which a pair of belts are arranged in an area corresponding to one card 50, and is provided at a position where each card 50 is placed before the delivery mode is executed. Thereby, in this example, each belt conveyor 502 functions as an individual card conveyance part which conveys a card | curd in each position in a conveyance direction. The individual card transport unit is, for example, a part in which the single card 50 is placed in the alignment unit 112, and is provided side by side along the transport direction of the card 50. In addition, each belt conveyor 502 rotates at a preset speed, so that the card 50 is conveyed at a speed corresponding to each mode in each operation of the delivery mode and the relay mode. With this configuration, for example, the alignment unit 112 can appropriately execute the operation in the sending mode and the relay mode.

  Here, as described above, when the card 50 is transported, setting the interval between the cards 50 to be equally divided leads to an increase in manufacturing efficiency. However, when a plurality of printing apparatuses 12 are used, it is necessary to appropriately synchronize the operation timing of each printing apparatus according to the distance between the apparatuses. Further, in this case, if the synchronization is inappropriate, there is a possibility that the gap between the cards 50 is shifted. In particular, as in this example, when a plurality of printing apparatuses 12 are used and a plurality of types of operation modes are switched and executed in each alignment unit 112, the operation timing of each printing apparatus 12 and alignment unit 112 is as follows. It is desirable to properly synchronize.

  On the other hand, in this example, the synchronization timing can be adjusted by using the relay unit 14 by the configuration in which the alignment unit 112 is connected by the relay unit 14. More specifically, in this example, the relay unit 14 is configured to be able to change the distance for transporting the card between the plurality of printing apparatuses 12, for example. With this configuration, for example, by adjusting the distance of the relay unit 14 as appropriate, complicated control such as timing control of movement start of each printing device 12 is performed with respect to synchronization of the operations of the plurality of printing devices 12. And can be adjusted appropriately. Thereby, for example, the interval between the cards 50 can be set to a more appropriate distance.

  Subsequently, the card inspection unit 44 and the stacker unit 46 provided in the collection unit 16 will be described in more detail. FIG. 13 is a photograph showing an example of the configuration of the card inspection unit 44 and the stacker unit 46. FIG. 13A shows an example of the configuration of the card inspection unit 44.

  The card inspection unit 44 is an inspection device that inspects the card 50 conveyed by the conveyance path 20 after printing, and optically inspects the card 50 using, for example, a camera. Further, in this example, the card inspection unit 44 further excludes the card 50 in which a defect is detected in the inspection, and arranges a replacement card at the excluded position instead of the excluded card 50. Thereby, for example, the distance between the cards in the transport direction is maintained at an equal interval also downstream of the card inspection unit 44 in the transport direction.

  According to this example, for example, it is possible to appropriately inspect the printed card 50. In this case, the cards 50 are transported at equal intervals in the state before the inspection. Therefore, it is possible to inspect at regular intervals, and it is possible to detect defects more easily. In addition, even after the inspection, if the defective card 50 is eliminated, the replacement cards are arranged so that the cards are sent at regular intervals. Therefore, handling of the card becomes easier in the subsequent processing.

  As the replacement card, for example, a card of a predetermined color different from the normal card 50 (for example, a red card) can be used. If comprised in this way, the position which excluded the defective card after collection | recovery of the card | curd 50 can be identified more easily.

  FIG. 13B shows an example of the configuration of the stacker unit 46. The stacker unit 46 is a portion that collects the cards 50 at the most downstream side of the post-printing conveyance path 20, and the cards 50 conveyed by the post-printing conveyance path 20 are dropped and stacked at the most downstream part of the post-printing conveyance path 20. To do. In this example, the card 50 is carried out from the back side to the front side of the drawing, but is configured to fall into the stacker unit 46 from the front side end portion of the post-printing conveyance path 20. Here, the upper surface of the bottom of the stacker unit 46 is controlled so as to move up and down in accordance with the loading amount of the cards 50. Further, the distance between the upper surface of the card 50 and the front end of the post-printing conveyance path 20 is controlled so as to be appropriately maintained. This appropriate distance corresponds to a distance in which only the end portion of the card 50 in the transport direction first collides with the inner wall of the stacker portion 46 when dropped. If the distance is too small, the card 50 may be in direct contact with the surface of the loaded card 50 before dropping, and if the distance is too large, there is a risk that the card will be inverted when dropped.

  According to this example, for example, the printed card 50 can be appropriately collected in the stacker unit 46. Further, in this case, when the card 50 falls on the stacker unit 46, it is placed on the loaded card 50 from one edge, so that the end of the dropped card 50 is placed on the surface of the loaded card 50 ( Contact with the printing surface is prevented. Therefore, if comprised in this way, a card | curd can be collect | recovered more appropriately, for example, preventing the rubbing of a printing surface.

  Next, the features of the alignment unit 112 will be described in more detail. As described with reference to FIG. 11B and the like, in this example, the alignment unit 112 includes a plurality of belt conveyors 502 each functioning as an individual card transport unit. In this case, it is preferable that the respective belt conveyors 502 can operate independently by switching between the delivery mode and the relay mode.

  Further, as the operation in the sending mode in the alignment unit 112, for example, an operation of intermittently repeating the conveyance and the temporary stop can be considered. With this configuration, for example, when it is desired to increase the interval between the cards 50, after sending out one card, the conveyance of the next card is temporarily stopped to stop the card 50 from moving downstream. Thus, the interval between the cards 50 can be freely adjusted. In this case, for example, it is conceivable to individually carry and temporarily stop each belt conveyor 502. If comprised in this way, about the space | interval of the card | curd 50 sent out downstream, for example, it can set appropriately with a desired space | interval.

  FIG. 14 is a diagram illustrating an example of a specific operation of the alignment unit 112, and illustrates an example of an operation in the case where the operation of each belt conveyor 502 is individually controlled. FIGS. 14A to 14D show an example of the operation of the alignment unit 112 in order along the time series.

  Here, in FIG. 14, in order to distinguish the several card | curd 50 to convey, each code | symbol AD is attached | subjected and shown about each card | curd 50. In FIG. Further, the belt conveyor 502 indicated by the letter “movement” on the belt conveyor 502 indicates the belt conveyor 502 that is performing the conveying operation. The belt conveyor 502 indicated by the letters “stop” indicates the belt conveyor 502 that is stopped after being stopped. Further, the belt conveyor 502 shown with the letters “start of movement” indicates the belt conveyor 502 at the timing when the stop state is finished and the conveyance is resumed.

  In the case shown in the figure, the plurality of belt conveyors 502 in the alignment unit 112 are arranged in a range of a predetermined distance L. That is, in this case, the distance between the upstream end and the downstream end in the transport direction in the arrangement of the plurality of belt conveyors 502 is L as shown in the drawing. Further, the aligning unit 112 sends out the cards 50 so that the distance between the cards 50 is set to a preset distance l with respect to the cards 50 sent out downstream. The distance l is set smaller than the distance L.

  Subsequently, the states shown in FIGS. 14A to 14D will be described. FIGS. 14A and 14B show an example of the state of the aligning unit 112 with respect to the timing at which the cards 50 labeled A and B are sent to the collecting unit 16 on the downstream side by the operation in the sending mode. In addition, at the timing shown in FIG. 14B, the card 50 with the symbol C is sent from the upstream side by the relay unit 14. Further, at this timing, the belt conveyor 502 on the most downstream side in the transport direction is stopped in a state in which the card 50 having the symbol B is placed. Thereby, this belt conveyor 502 adjusts the space | interval between the card | curd 50 which attached | subjected the code | symbol A, and the card | curd 50 which attached | subjected the code | symbol B. FIG.

  FIGS. 14C and 14D show the state of the aligning unit 112 with respect to the timing at which the card 50 attached with the symbol B is sent out and the card 50 attached with the symbol C, which is the card 50 sent from the upstream, is conveyed. An example is shown. At the timing shown in FIG. 14C, the most downstream belt conveyor 502 resumes operation and sends out the card 50 labeled B to the downstream side. As a result, as shown in FIG. 14 (d), the interval between the card 50 with the symbol A and the card 50 with the symbol B is adjusted to a predetermined interval l.

  In this configuration, the plurality of belt conveyors 502 are configured to be able to operate independently of each other. More specifically, in this case, each belt conveyor 502 is configured to be able to individually switch between the delivery mode and the relay mode. Therefore, in this case, at least at some timing, among the plurality of belt conveyors 502 in one alignment unit 112, some of the belt conveyors 502 on the downstream side perform the operation in the delivery mode, and some of the upstream side conveyors 502 The belt conveyor 502 can operate in the relay mode. More specifically, for example, in the case shown in FIGS. 14C and 14D, the belt conveyor 502 is made to perform the operation of the delivery mode on the downstream side where the card 50 with the symbol B is sent, and the symbol C is designated as C. It is conceivable that the upstream-side belt conveyor 502 carrying the attached card 50 is operated in the relay mode.

  If comprised in this way, switching of an operation mode can be performed more flexibly, for example. In addition, by making it possible to individually switch the operation mode of the belt conveyor 502, it is possible to more appropriately set the card conveyance speed in each unit of the alignment unit 112. Therefore, if comprised in this way, about the space | interval l of the card sent out to the downstream of the alignment part 112, it can match appropriately with a desired space | interval.

  In FIGS. 14C and 14D, for example, the interval between the card 50 with the symbol B and the card 50 with the symbol C is also the interval l. In FIG. 14 (d), the interval between the card 50 with the reference C and the card 50 with the reference D sent subsequently is also the interval l.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
