The gear 83c is arranged so as to mesh with the gear 86b of the take-up motor 86a in the non-protruding state, whereby the second roller 81b is rotated by the driving force from the take-up motor 86a to wind up the cleaning member 82. It has become like. Further, the box body 83a has protruding portions 83d protruding from the mounting member 83 on both sides in the left-right direction. In the present embodiment, one protrusion 83d is arranged on the right side of the box body 83a, and two protrusions 83d are arranged on the left side of the box body 83a. The plurality of protrusions 83d function as engaging portions that engage with the protrusion holding portions 142 of the cleaning member transport jig 140 shown in FIG. On the front surface of the box body 83a, receiving members 83e are arranged on each of the left and right ends. The receiving member 83e has recesses that open toward the left and right outer sides, and is configured to engage with the lock member 86d of the lock mechanism 86c in the non-protruding state. An opening 83f is formed on each of the left and right side surfaces of the box body 83a, and an engaging shaft 83g extending in the Y direction is arranged in the opening 83f. The engaging shaft 83g is configured to engage with the claw member 84c of the mounting member 84 (enlarged view in the upper right of FIG. 8).

The mounting member 84 is configured as a plate-shaped member on which the replacement module 81 is mounted and supported from below. The mounting member 84 and the mounting member 83 serve as a cleaning head, and are moved back and forth by the cleaning moving portion 87. An abutting member 84a, an elevating device 84b, a claw member 84c, and a connecting portion 84d are arranged on the upper surface of the mounting member 84. The contact member 84a is a member that supports the cleaning member 82 from below. The elevating device 84b is configured as, for example, an air cylinder, and elevates and elevates the contact member 84a while supporting it from below. When the elevating device 84b raises the contact member 84a, the contact member 84a lifts the cleaning member 82 upward so that the upper surface of the cleaning member 82 comes into contact with the back surface of the screen mask 55. In this state, the cleaning moving unit 87 moves the mounting member 84, so that the cleaning unit 80 performs a cleaning process in which the solder on the back surface of the screen mask 55 is wiped off by the cleaning member 82. The claw member 84c is a member for preventing the replacement module 81 from falling off from the mounting member 84 when the mounting member 84 moves in the Y direction, and is arranged one on each side of the mounting member 84. ing. The claw member 84c is a substantially square columnar member whose longitudinal direction is along the vertical direction. The claw member 84c has an inclined surface on the inner side of the upper end in the left-right direction (inside of the mounting member 83), and a recess for engaging with the engaging shaft 83g of the mounting member 83 is formed below the inclined surface.

As a result, when the replacement module 81 descends from above the mounting member 84, the engaging shaft 83 g of the mounting member 83 of the replacement module 81 is guided by the inclined surface of the claw member 84c to form a recess of the claw member 84c. Engagement restricts the relative movement of the mounting member 83 and the mounting member 84 in the Y direction. When the replacement module 81 tries to move upward from the mounting member 84, the elastic force of the elastic member that urges the claw member 84c is applied so that the engagement between the engaging shaft 83g and the claw member 84c is released. It has been adjusted. The connecting portion 84d is a member connected to the connecting portion 89b of the mounting member moving mechanism 89, and is arranged on the rear side of the mounting member 84.

As shown in FIG. 1, the support member 86 is a plate-shaped member whose left and right ends are supported by guide rails 88b. As a result, the support member 86 supports the mounting member 84 from the left-right direction along the horizontal direction. A take-up motor 86a and a lock mechanism 86c are arranged on the support member 86. The take-up motor 86a is arranged on the right side of the mounting member 83 of the support member 86, and rotates the gear 83c and the second roller 81b via the gear 86b. For example, in the cleaning unit 80, the take-up motor 86a rotates the second roller 81b during a certain period of time after the cleaning process, so that the portion of the cleaning member 82 that has been cleaned, that is, the portion to which the solder has adhered is first. 2 Performs sheet feeding processing to be carried into the roller 81b. The lock mechanism 86c is configured as, for example, an air cylinder, and is a mechanism for projecting the lock member 86d in the X direction via the cylinder. One lock mechanism 86c is arranged on each of the left and right sides of the mounting member 83 of the support member 86. As shown in FIG. 9, when the lock mechanism 86c projects the lock member 86d toward the mounting member 83 when the replacement module 81 and the mounting member 84 are in the non-protruding state, the lock member 86d of the mounting member 83 They are inserted into the recesses of the receiving member 83e and engage with each other. As a result, the replacement module 81 and the mounting member 84 are restricted from moving relative to the support member 86 in the Y direction, and are fixed in a non-protruding state. On the other hand, as shown in FIG. 8, when the lock mechanism 86c does not project the lock member 86d, the replacement module 81 and the mounting member 84 can be switched between the protruding state and the non-projecting state by the mounting member moving mechanism 89.

The support member moving mechanism 88 also moves the replacement module 81 and the mounting member 84 in the Y direction by moving the support member 86 in the Y direction. As shown in FIGS. 8 and 9, the mounting member moving mechanism 89 is arranged at the tip of the cylinder rod of the drive source 89a configured as, for example, an air cylinder and the mounting member 84, and is connected to the mounting member 84. It is provided with a connecting portion 89b connected to the 84d. Further, the mounting member moving mechanism 89 includes a telescopic rail 89c which is arranged on the support member 86 and includes a plurality of rails that slide in the Y direction. When a driving force in the Y direction from the drive source 89a acts on the mounting member 84 via the connecting portion 89b and the connecting portion 84d, the telescopic rail 89c expands and contracts, so that the mounting member 84 is Y with respect to the support member 86. Move relative to the direction. As a result, the mounting member moving mechanism 89 has a protruding state (FIG. 8) in which the replacement module 81 and the mounting member 84 project forward relative to the support member 86, and the replacement module 81 and the mounting member 84. It is possible to switch between a non-protruding state (FIG. 9) in which the support member 86 does not protrude relatively forward. The cleaning moving unit 87 uses the support member moving mechanism 88 and the mounting member moving mechanism 89 to clean the cleaning member 82 with the cleaning member 82 to clean the screen mask 55, and the cleaning member 82 with the cleaning member transport jig 140. Move between exchange positions. The cleaning position is, for example, a position directly below the screen mask 55 fixed to the mask fixing portion 51. The replacement position is, for example, a position where the replacement module 81 is delivered between the cleaning member transport jig 140 and the cleaning unit 80. Further, the cleaning moving unit 87 carries in and out the cleaning member 82 and the replacement module 81 including the cleaning member 82.

More specifically, one protrusion holding portion 142 is arranged on the right side and two on the left side. The protrusion holding portion 142 has a recess formed on the upper surface thereof, and engages with the protrusion 83d mounted on the recess to support the protrusion 83d from below. By engaging the protrusion 83d with the recess, the cleaning member transport jig 140 can transport the replacement module 81 while fixing the relative position of the replacement module 81 in the front-rear direction. The barcode 146 is identification information for identifying the cleaning member 82 attached to the cleaning member transport jig 140, and is attached in advance by, for example, an operator.

The reading unit 97 is a device that reads information about one or more of the replaceable members 13, and is configured as a bar code reader in this embodiment. As shown in FIG. 1, the reading unit 97 is arranged in the front right of the printing apparatus 10, and the left direction is the reading direction. The reading unit 97 is arranged at the same height as the height at which the screen mask 55 is carried in and out (carry-in height and carry-out height), and the barcode 57a attached to the right side surface of the screen mask 55 (FIG. 5). ) Can be read. Further, the reading unit 97 can read the barcodes 116, 126, 136, 146 attached to each of the transport jigs 110, 120, 130, 140 if they are transported to the same height. it can.

A moving portion such as a caster is arranged on the lower surface of the housing 101 so that, for example, an operator can move the storage device 100. The storage unit 102 is a box body capable of storing the replaceable member 13 and the transfer jig, and a plurality of transfer conveyors 104 are arranged inside. The conveyors 104 are arranged in a plurality of stages in the vertical direction, and in the present embodiment, the first to ninth conveyors 104a to 104i are arranged in order from the top as shown in FIG. Each of the first to ninth conveyors 104a to 104i is configured as a pair of left and right belt conveyors, and conveys the placed object in the front-rear direction. Note that, for convenience of illustration, FIG. 1 shows only four stages of the conveyor 104. The storage unit 102 is configured so that at least one replaceable member 13 can be placed on each of the first to ninth conveyors 104a to 104i. Further, the storage unit 102 has a plurality of storage areas 103 in the vertical direction divided by the first to ninth conveyors 104a to 104i. The storage area 103 has a first storage area 103a as an area above the first conveyor 104a, and similarly, a second second as an area above each of the second to ninth conveyors 104b to 104i. It has a ninth storage area 103b to 103i. The storage area 103 does not necessarily have to be inside the storage unit 102. For example, the cartridge transfer jig 120 mounted on the first transfer conveyor 104a shown in FIG. 2 partially protrudes rearward from the storage portion 102, and the area where the protruding portion exists is also included in the first storage area 103a. Is done. The front and rear of the storage portion 102 are open. As a result, the operator can insert the replaceable member 13 into the storage unit 102 from the front, and the storage device 100 can carry the replaceable member 13 into and out of the printing device 10 via the rear of the storage unit 102. .. The conveyor elevating part 105 is a mechanism for raising and lowering the storage part 102 up and down, and includes, for example, a guide (not shown), a ball screw, and a drive motor. When the conveyor elevating unit 105 raises and lowers the storage unit 102, the conveyor 104 moves up and down.

In the present embodiment, the cartridge transfer jig 120 is placed on the first transfer conveyor 104a, the squeegee transfer jig 110 is placed on the second and third transfer conveyors 104b and 104c, and the fourth and fifth transfer jigs 110 are placed.

The support member transfer jig 130 is configured to be placed on the top. The distance between the vertically adjacent conveyors 104 is adjusted according to the heights of the conveyors mounted on the respective conveyors 104 and the replaceable members 13 attached to the jigs. The widths of the transfer jigs 110 to 140 and the screen mask 55 are defined so that they can be placed on any of the plurality of transfer conveyors 104. For example, the widths in the left and right directions are substantially the same. It has become.

The storage control unit 106 is configured as a microprocessor centered on a CPU, and includes a ROM for storing a processing program, a RAM used as a work area, an HDD for storing various data, and the like. The storage control unit 106 controls the entire storage device 100.

Next, the operation of the printing system 1 configured in this way will be described. First, a printing process executed by the printing device 10 and a reading process for reading the identification information of the replaceable member 13 stored in the storage device 100 in parallel with the printing process will be described. FIG. 10 is an explanatory diagram showing how the printing process and the reading process are performed in parallel.

First, the printing process will be described. The print processing routine for performing the print process is stored in the HDD of the print control unit 11, and after the print control unit 11 inputs an execution instruction of the print process from the operator via the display operation unit 98, or the print control unit. 11 is executed after inputting the execution command of the print process from the management PC 150. When the print processing routine is started, the print control unit 11 first performs a substrate transfer fixing process in which the substrate S is fixed by the substrate fixing portion 60 and brought into contact with the screen mask 55 as shown in FIG. Specifically, the print control unit 11 first drives the substrate transfer conveyor 61 to transfer the substrate S to the substrate fixing unit 60, and sandwiches and fixes the substrate S by the substrate guide 62. Further, the print control unit 11 adjusts the position of the screen mask 55 by the mask working unit 50 as necessary, and aligns the pattern hole 58 with the substrate S. Next, the print control unit 11 raises the support base 67 to bring the upper surface of the substrate support member 70 into contact with the lower surface of the substrate S, and attracts and fixes the substrate S to the substrate support member 70 by negative pressure from the decompression device. To do. Then, the print control unit 11 raises the substrate fixing portion 60 to bring the upper surface of the substrate S into contact with the lower surface of the screen mask 55. When the substrate transfer fixing process is performed, the print control unit 11 performs the solder supply process. Specifically, the print control unit 11 moves the supply head 41 onto the screen mask 55, supplies air from the air supply unit 42, and discharges solder from the cartridge 49 onto the screen mask 55. When the solder supply process is performed, the print control unit 11 performs the squeegee movement process. Specifically, the print control unit 11 moves the print head 21 and lowers the squeegee 30 (the first squeegee 30a in FIG. 10) to bring the squeegee 30 into contact with the upper surface of the screen mask 55, and moves the squeegee 30 back and forth. The solder is printed on the substrate S by moving in the direction. The print control unit 11 performs at least one of a process of moving the first squeegee 30a backward and a process of moving the second squeegee 30b forward on the screen mask 55. In this way, the print control unit 11 performs printing processing including substrate transfer fixing processing, solder supply processing, and squeegee movement processing, and prints on the substrate S. The print control unit 11 repeats this print process until the production process is completed. The printing process may include the cleaning process and the sheet feed process described above. The print control unit 11 cleans the back surface of the screen mask 55 by performing a cleaning process and a sheet feed process at a predetermined timing, for example, every time a predetermined time elapses or every printing process of a predetermined number of substrates S.

While the printing device 10 is performing this printing process, the operator may replace the replaceable member 13 with the storage device 100 in advance in case one or more of the replaceable members 13 need to be replaced, for example, by setting up. The replaceable member 13 is stored. For example, when it is necessary to replace all of the five types of replaceable members 13 at the time of the next setup change, the operator can replace each transfer jig and the replaceable member 13 attached to the storage device 100 as shown in FIG. The member 13 is stored. Specifically, as shown in FIG. 2, the operator stores the cartridge transfer jig 120 with the replacement cartridge 49 attached to the holder 122 in the first storage area 103a. At this time, as shown in FIG. 5, the operator leaves at least one of the plurality of holders 122 of the cartridge transfer jig 120 in an empty state. The operator stores the empty squeegee transfer jig 110 in the second storage area 103b, and stores the squeegee transfer jig 110 to which two replacement squeegees 30 are attached in the third storage area 103c. The operator stores the empty cleaning member transport jig 140 in the fourth storage area 103d, and stores the cleaning member transport jig 140 to which the replacement module 81 for replacement is attached in the fifth storage area 103e. The operator reserves the sixth storage area 103f for carrying out the screen mask 55 in use from the printing device 10, and stores the replacement screen mask 55 in the seventh storage area 103g. The operator stores the vacant support member transfer jig 130 in the eighth storage area 103h, and stores the support member transfer jig 130 to which one replacement board support member 70 is attached in the ninth storage area 103i. .. In this way, the operator stores the replaceable replaceable member 13 in advance while the printing device 10 is performing the printing process, not when the replaceable member 13 needs to be replaced such as setup change. It may be stored in 100. Therefore, the worker can perform the work of preparing the replaceable member 13 for replacement at a time when the work load is small.

In addition, the operator attaches a bar code indicating identification information of the replaceable member 13 attached to the transfer jig to each transfer jig in advance. For example, the operator sets the identification information included in the barcode 126 of the cartridge transfer jig 120 to include information indicating the type of the cartridge 49 attached to the cartridge transfer jig 120. Similarly, the operator sets the identification information included in the barcode 57a of the screen mask 55 to include information indicating the type of the screen mask 55. By doing so, the print control unit 11 causes the reading unit 97 to read the barcode of each transfer jig and the screen mask 55, so that which of the five types of replaceable members 13 is related to. Can be identified. Further, the print control unit 11 identifies a fine type in the replaceable member 13 of the same type, such as which type of cartridge 49 among the plurality of types of cartridges 49 is attached to the cartridge transfer jig 120. You can also do it. The barcode may also include information indicating the state of each transfer jig (whether or not there is a vacant holder, etc.). For example, the barcode 126 of the cartridge transfer jig 120 includes information on which of the plurality of holders 122 of the cartridge transfer jig 120 the cartridge 49 is attached to (which holder 122 is empty). You may be.

Next, the reading process will be described. The reading processing routine for performing the reading process is stored in the HDD of the print control unit 11, and is executed, for example, every predetermined time elapses or after the operator inputs an execution instruction for the reading process. When the reading processing routine is started, the print control unit 11 can read the replaceable member 13 or the empty transfer jig stored in the storage unit 102 to the storage control unit 106 of the storage device 100. A command is output to move the jigs to different positions in sequence. Upon receiving this command, the storage control unit 106 first raises and lowers the storage unit 102 by the conveyor elevating unit 105 so that the cartridge transfer jig 120 on the first transfer conveyor 104a is located at the same height as the reading unit 97. Further, the storage control unit 106 conveys the cartridge transfer jig 120 in the Y direction by the first transfer conveyor 104a as needed, moves the barcode 126 to a position where the reading unit 97 can read, and then transfers the cartridge. The jig 120 is conveyed and returned to its original position. During this time, the print control unit 11 causes the reading unit 97 to read the barcode 126 and stores the acquired information in the HDD. The storage control unit 106 sequentially performs the same processing on the second conveyor 104b to the ninth conveyor 104i. FIG. 10 shows a state in which the storage device 100 conveys the squeegee transfer jig 110 stored in the second storage area 103b to a position where the reading unit 97 can read it. As described above, in the reading process, the print control unit 11 causes the storage device 100 to perform at least one of transporting and raising / lowering the replaceable member 13 as a movement to a position where the reading unit 97 can read. By this reading process, the print control unit 11 indicates the information of the replaceable member 13 stored in each of the storage areas 103 of the storage device 100, and which type of transfer jig is stored in each of the storage areas 103. Acquires and stores information necessary for the exchange process described later, such as information. Further, the print control unit 11 detects that the state in which the reading unit 97 does not read the information continues for a predetermined time even if the information is conveyed by the conveyor 104, so that the transfer jig is not stored in the empty state. The storage area 103 (sixth storage area 103f in FIG. 10) can also be specified. As shown in FIG. 10, the reading unit 97 is arranged on the front side of the printing apparatus 10. Therefore, even if the replaceable member 13 or the like is conveyed from the front storage device 100 to the reading position of the reading unit 97, the printing processing unit 20, the supply unit 40, the mask working unit 50, the substrate fixing unit 60, etc. in the above-mentioned printing process. There is no problem in the operation of the cleaning unit 80. Therefore, the print control unit 11 can perform the reading process in parallel with the printing process. As a result, the print control unit 11 can acquire information on the replaceable member 13 and the transfer jig stored in the storage device 100 without stopping the printing process.

Regarding the operation on the storage device 100 side during the reading process, the operation routine at the time of the reading process is stored in advance in the storage unit of the storage control unit 106, and the print control unit 11 only outputs the start command of the operation routine. You may. Alternatively, the print control unit 11 may sequentially output individual operation commands of the conveyor elevating unit 105 and the conveyor 104 to the storage control unit 106.

Next, a replacement process for automatically replacing the replaceable member 13 will be described. FIG. 11 is a flowchart showing an example of the exchange processing routine. This exchange processing routine is stored in the HDD of the print control unit 11. The print control unit 11 differs from the current print process in one or more of the replaceable members 13 required for the next print process each time the print process is completed, for example, based on the information about the print process acquired from the management PC 150. It is determined whether or not the replacement process is necessary. Then, when the print control unit 11 determines that the exchange process is necessary, the print control unit 11 starts the exchange process routine. The print control unit 11 performs the exchange processing routine while appropriately referring to the information acquired in the above-mentioned reading process.

When the print control unit 11 starts the replacement processing routine, the cartridge replacement processing (step S100), cleaning member replacement processing (step S110), mask carry-out processing (step S120), squeegee replacement processing (step S130), and substrate support member replacement One or more of the process (step S140) and the mask carry-in process (step S150) are performed as necessary. Since the cartridge 49 and the cleaning member 82 are consumables, not only when each type is changed, but also at least one of the cartridge replacement process and the cleaning member replacement process is combined when it is necessary to execute the replacement process. The consumables may be replenished without changing the type of consumables. For example, when one or more of the squeegee 30, the screen mask 55, and the substrate support member 70 need to be replaced, at least one of the cartridge 49 and the cleaning member 82 may be replaced together. Further, in the present embodiment, when the screen mask 55, the squeegee 30, and the substrate support member 70 are replaced, the transfer jig is conveyed by using the transfer rail 53 in each case. Therefore, when it is necessary to perform at least one of the squeegee replacement process and the substrate support member replacement process, the mask unloading process is performed prior to these processes to retract the screen mask 55 from the transport rail 53, and these processes are performed. The mask carry-in process is performed after the process. Further, the process including the mask carry-out process and the mask carry-in process corresponds to the mask exchange process. When it is not necessary to replace the screen mask 55, the screen mask 55 carried out in the mask carry-out process is carried in in the mask carry-in process. Hereinafter, each process of steps S100 to S150 will be described by taking the case where all five types of replaceable members 13 are replaced as an example.

The cartridge replacement process in step S100 will be described. FIG. 12 is an explanatory diagram of an operation of mounting the cartridge 49 on the supply head 41. When the cartridge replacement process is started, the print control unit 11 performs a cartridge carry-out process for carrying out the cartridge 49 attached to the supply head 41 and a cartridge carry-in process for carrying in the replacement cartridge 49. In the cartridge unloading process, the print control unit 11 first positions the cartridge transport jig 120 having an empty holder 122 on the first conveyor 104a at a height (loading height) for unloading the cartridge 49. In addition, the conveyor elevating part 105 is operated. The carry-out height of the cartridge 49 is such that the cartridge 49 mounted on the supply head 41 can be attached to the empty holder 122, and the main body 49a can be inserted into the opening 124. .. Next, the print control unit 11 controls the print movement unit 22 and the supply movement unit 46 to a delivery position where the cartridge 49 attached to the supply head 41 can be attached to the empty holder 122 of the cartridge transfer jig 120. Move. Subsequently, the print control unit 11 disengages the cartridge 49 from the supply head 41 and attaches the cartridge 49 to the empty holder 122. In the cartridge carry-in process, the print control unit 11 first operates the conveyor elevating part 105 so that the cartridge transfer jig 120 is positioned at a height (carry-in height) for carrying in the replacement cartridge 49. In this embodiment, the carry-in height and the carry-out height of the cartridge 49 are the same, and the process of operating the conveyor elevating part 105 is omitted. Next, the print control unit 11 moves the supply head 41 to a receiving position where the replacement cartridge 49 attached to the holder 122 can be received, and mounts the replacement cartridge 49 on the supply head 41. When the cartridge carry-out process and the cartridge carry-in process are performed as described above, the print control unit 11 ends the cartridge replacement process.

When attaching the cartridge 49 to the empty holder 122 in the cartridge unloading process, the print control unit 11 first inserts the main body 49a into the opening 124 of the holder 122 (an example of the delivery position) and holds the clamp portion 43. Rotate to the release position. Then, as the clamp portion 43 rotates, the cartridge 49 is lowered, and the cartridge 49 is supported by the support portion 123 with the flange portion 49b fitted in the engaging portion 125. When mounting the replacement cartridge 49 on the supply head 41 in the cartridge loading process, the print control unit 11 first has a state in which the connection portion 49d of the replacement cartridge 49 is located directly below the air supply unit 42 (receipt). In an example of the position, FIG. 12A), the clamp portion 43 is rotated to a fixed position (FIG. 12B). When the clamp portion 43 is positioned at the fixed position, the clamp portion 43 pushes up the cartridge 49 to disengage the flange portion 49b from the engaging portion 125 and positions the cartridge 49 at the outer position. At this time, the air supply unit 42 is inserted into the connection unit 49d, the cartridge 49 is positioned, and the supply head 41 can supply air to the main body unit 49a. Then, the print control unit 11 moves the supply head 41 so that the main body portion 49a passes through the opening 124 (FIG. 12B).

The cleaning member replacement process in step S110 will be described. When the cleaning member replacement process is started, the print control unit 11 performs a cleaning member carry-out process for carrying out the replacement module 81 and a cleaning member carry-in process for carrying in the replacement replacement module 81. FIG. 13 is an explanatory view showing a state of the cleaning member carry-out process. FIG. 14 is an explanatory view showing a state of the cleaning member carry-in process. In the cleaning member unloading process, the print control unit 11 first operates the conveyor elevating section 105 so that the empty cleaning member transport jig 140 is located at the height (unloading height) for unloading the replacement module 81. (Fig. 13A). Here, the print control unit 11 raises and lowers the fourth conveyor 104d on which the empty cleaning member transfer jig 140 is placed to the carry-out height. The carry-out height of the replacement module 81 is such that the protrusion holding portion 142 of the cleaning member transport jig 140 is located below the protrusion 83d of the replacement module 81 attached to the mounting member 84. Further, the print control unit 11 controls the support member moving mechanism 88 to move the replacement module 81 to the front of the printing device 10 (FIG. 13A). The position of the replacement module 81 at this time may be, for example, the position of the front end of the region in which the replacement module 81 can be moved by the support member moving mechanism 88, or may be the initial position of the replacement module 81. Next, the print control unit 11 controls the mounting member moving mechanism 89 to bring the mounting member 84 into a protruding state, thereby moving the replacement module 81 to a delivery position where it can be attached to the cleaning member transport jig 140. (Fig. 13B). The delivery position is inside the storage unit 102 in the present embodiment, and the operation of the print control unit 11 moving the replacement module 81 to the delivery position also serves as the unloading operation of the replacement module 81. In this state, each of the plurality of protrusions 83d of the replacement module 81 is located directly above each of the plurality of protrusion holding portions 142 of the cleaning member transport jig 140. Subsequently, the print control unit 11 raises the storage unit 102 by the conveyor elevating unit 105. As a result, the protrusion holding portion 142 and the protrusion 83d are engaged with each other, the replacement module 81 is attached to the cleaning member transport jig 140 and rises, and the replacement module 81 is removed from the mounting member 84 (FIG. 13C). .. As described above, the replacement module 81 is carried out and delivered to the cleaning member transfer jig 140. After that, the print control unit 11 puts the mounting member 84 in a non-protruding state (FIG. 13D).

In the cleaning member carry-in process, the print control unit 11 first raises the height (see FIG. 13C) of the uppermost end (here, the upper end of the contact member 84a) of the mounting member 84 in the protruding state, and the conveyor 104 The conveyor elevating section 105 is operated so that the replacement replacement module 81 on (here, the fifth conveyor 104e) is located (FIG. 14A). Next, the print control unit 11 controls the mounting member moving mechanism 89 to bring the mounting member 84 into a protruding state, so that the replacement module 81 is mounted at a receiving position where it can be received from the cleaning member transport jig 140. The member 84 is moved (FIG. 14B). At this receiving position, the mounting member 84 is located directly below the replacement module 81 for replacement. Subsequently, the storage unit 102 is lowered so that the cleaning member transfer jig 140 on the fifth transfer conveyor 104e is located at the height for carrying in the replacement module 81 (carry-in height), and then further than the carry-in height. Lower (Fig. 14C). As a result, the replacement module 81 is attached to the mounting member 84, and the cleaning member transport jig 140 is further lowered to release the engagement between the protrusion holding portion 142 and the protrusion 83d. The carry-in height of the replacement module 81 is the height when the replacement replacement module 81 is lowered and attached to the mounting member 84. Then, the print control unit 11 brings the replacement module 81 into the printing device 10 by making the mounting member 84 non-protruding (FIG. 14D). As described above, the replacement module 81 is received from the cleaning member transfer jig 140 and is carried into the printing apparatus 10. When the cleaning member carry-out process and the cleaning member carry-in process are performed as described above, the print control unit 11 ends the cleaning member replacement process.

The mask unloading process in step S120 will be described. FIG. 15 is an explanatory diagram showing a state of mask unloading processing. When the mask unloading process is started, the print control unit 11 first positions a vacant conveyor 104 (here, the sixth conveyor 104f) at a height (unloading height) for unloading the screen mask 55. The conveyor elevating part 105 is operated as described above. The carry-out height of the screen mask 55 is such that the sixth conveyor 104f and the conveyor rail 53 are at the same height. Next, the print control unit 11 projects the transfer rod 38 downward and controls the print movement unit 22 to transfer the screen mask 55 forward along the transfer rail 53 (FIG. 15). Then, the print control unit 11 conveys the screen mask 55 to the sixth conveyor 104f by the conveying rod 38 and carries out the screen mask 55. Further, the print control unit 11 conveys the screen mask 55 further forward by the sixth conveyor 104f, and stores the screen mask 55 in the storage unit 102. As a result, the screen mask 55 is removed from the transfer rail 53, and other transfer jigs can be easily transferred on the transfer rail 53. In FIG. 15, the transport rod 38 transports the screen mask 55 by pushing the end portion (rear end in this case) from the outside, but the present invention is not limited to this, and for example, by pushing the inside of the frame body 57. The screen mask 55 may be conveyed. Similarly, in the transfer of a transfer jig such as the squeegee transfer jig 110 described later, the transfer rod 38 may push the end portion of the transfer jig from the outside, or the inside of the transfer jig (for example, the inside of the frame 111). Alternatively, the replaceable member 13 attached to the transfer jig may be pushed.

The squeegee replacement process in step S130 will be described. When the squeegee replacement process is started, the print control unit 11 performs a squeegee carry-out process for carrying out the squeegee 30 and a squeegee carry-in process for carrying in the replacement squeegee 30. FIG. 16 is an explanatory diagram showing a state of the squeegee unloading process. In the squeegee unloading process, the print control unit 11 first raises the conveyor 104 (here, the second conveyor 104b) on which the squeegee conveyor 110 having an empty holder 112 is placed and the conveyor rail 53 at the same height. The conveyor elevating part 105 is operated so as to reach the height (delivery height). That is, the print control unit 11 positions the second conveyor 104b at the same height as the carry-out height of the screen mask 55 described above. Then, the second transfer conveyor 104b and the transfer rod 38 are controlled to carry the squeegee transfer jig 110 into the printing device 10 (FIG. 16A). Next, the print control unit 11 controls the print moving unit 22 and the squeegee elevating unit 23 to move the first squeegee 30a attached to the squeegee fixing unit 24 forward, and the empty space on the front side of the squeegee transfer jig 110 is empty. The first squeegee 30a is attached to the holder 112 (FIG. 16B). Similarly, the print control unit 11 moves the second squeegee 30b rearward and attaches the second squeegee 30b to the empty holder 112 on the rear side of the squeegee transfer jig 110 (FIG. 16C). Then, the print control unit 11 conveys the squeegee transfer jig 110 to which the squeegee 30 is attached to the second transfer conveyor 104b by the transfer rod 38, and carries out the squeegee transfer jig 110 (FIG. 16D). Further, the print control unit 11 further conveys the squeegee transfer jig 110 forward by the second transfer conveyor 104b, and stores the squeegee transfer jig 110 in the storage unit 102.

In the squeegee carry-in process, the print control unit 11 carries in the squeegee 30 in the reverse procedure of the squeegee carry-out process described above. That is, the print control unit 11 first arranges that the third conveyor 104c on which the squeegee transfer jig 110 to which the replacement squeegee 30 is mounted and the transfer rail 53 have the same height (carry-in height). The conveyor elevating part 105 is operated. Next, the print control unit 11 carries in the squeegee transfer jig 110 by the third transfer conveyor 104c and the transfer rod 38. Subsequently, the print control unit 11 controls the print moving unit 22 and the squeegee elevating unit 23 to move the squeegee fixing unit 24 on the front side forward, and the squeegee 30 attached to the holder 112 on the front side of the squeegee transfer jig 110. Is attached to the squeegee fixing portion 24 on the front side. Similarly, the print control unit 11 moves the rear squeegee fixing portion 24 rearward, and attaches the squeegee 30 attached to the rear holder 112 of the squeegee transfer jig 110 to the rear squeegee fixing portion 24. After that, the print control unit 11 carries out the squeegee transfer jig 110 from which the squeegee 30 has been removed by the transfer rod 38, and stores the squeegee transfer jig 110 in the storage unit 102 by the third transfer conveyor 104c.

Here, the delivery of the squeegee 30 from the squeegee fixing portion 24 to the holder 112 and the reception of the replacement squeegee 30 from the holder 112 to the squeegee fixing portion 24 will be described in detail. For convenience of explanation, the receipt of the squeegee 30 will be described first. FIG. 17 is an explanatory diagram of an operation of attaching the squeegee 30 to the squeegee fixing portion 24. Note that FIG. 17 shows how the squeegee fixing portion 24 on the front side receives the squeegee 30. The left column of FIG. 17 is a schematic cross-sectional view of the positioning member 33 and the air cylinder 25 along the vertical and front-rear directions, and the central row of FIG. 17 is a schematic cross-sectional view of the regulating member 26 and the shaft member 35 along the vertical and front-rear directions. FIG. 17 is a perspective view of the squeegee fixing portion 24 and the squeegee 30 as viewed from the upper right front. When receiving the squeegee 30, the print control unit 11 first lowers the squeegee fixing portion 24 to release the squeegee fixing portion 24, and moves the squeegee fixing portion 24 forward from the rear of the squeegee 30 to be received. (Fig. 16B, Fig. 17A). As a result, the cylinder shaft 25a is inserted into the opening 33a of the squeegee 30. At this time, the shaft member 35 of the squeegee 30 is inserted between the claws 27a and 27b of the regulation member 26. Then, at a position where the cylinder shaft 25a comes into contact with the positioning member 33 and the forward movement of the cylinder shaft 25a is restricted by the positioning member 33, both are positioned in the front-rear direction (FIG. 17B). This position is the receiving position of the squeegee 30. In the present embodiment, the receiving position is a position where the rear surface of the positioning member 33 facing the opening 33a (the dead end portion of the opening 33a) and the front surface of the cylinder shaft 25a come into contact with each other. However, the receiving position may be a position where the flange 25b and the positioning member 33 come into contact with each other and the forward movement of the flange 25b is restricted by the positioning member 33. Further, when the squeegee fixing portion 24 is located at the receiving position, the recess 28a of the regulating member 26 is located directly above the protruding portion 34 of the squeegee 30 (FIG. 17B). Subsequently, the print control unit 11 controls the air cylinder 25 to switch the squeegee fixing unit 24 from the released state to the fixed state (FIG. 17C). As a result, the flange 25b rises to the fixed position and pushes up the gripped surface 33b of the positioning member 33. As a result, the flange portion 36 is pushed up, the engagement between the flange portion 36 and the engaging portion 115 of the holder 112 is released, and the squeegee 30 moves to the removal position. Further, as a result, the protruding portion 34 of the squeegee 30 rises and fits into the recesses 28a and 28b of the squeegee fixing portion 24 and engages with the regulating member 26. By engaging the regulating member 26 and the protruding portion 34, the movement of the squeegee 30 with respect to the squeegee fixing portion 24 in the front-rear direction is restricted. Further, in the fixed state, the gripped surface 33b, which is the lower surface of the positioning member 33, and the gripped surface 32a, which is the upper surface of the mounting member 32, are formed on the upper surface of the cylinder shaft 25a of the squeegee fixing portion 24 and the lower surface of the regulating member 26. By being sandwiched, the squeegee 30 is gripped and fixed to the squeegee fixing portion 24. Then, the print control unit 11 controls the print movement unit 22 to move the squeegee fixing unit 24 rearward. As a result, the flange portion 36 of the squeegee 30 passes through the opening 114, and the squeegee 30 is completely removed from the holder 112 (FIG. 17D). When the replacement second squeegee 30b is received from the holder 112 on the rear side of the squeegee transfer jig 110 to the squeegee fixing portion 24, the print control unit 11 may perform an operation symmetrical with respect to the above operation.

Delivery of the squeegee 30 from the squeegee fixing portion 24 to the holder 112 can be performed in the reverse procedure of the above reception. When the first squeegee 30a is delivered to the holder 112 on the front side of the squeegee transfer jig 110, the print control unit 11 first lowers the squeegee fixing portion 24 on the front side, and then lowers the squeegee fixing portion 24 from the rear of the holder 112. Move it forward. As a result, the flange portion 36 is positioned directly above the engaging portion 115 of the empty holder 112. This position is the delivery position of the squeegee 30. Next, the print control unit 11 switches the squeegee fixing unit 24 from the fixed state to the released state. As a result, the engaging portion 115 and the flange portion 36 are engaged with each other, the squeegee 30 is positioned at the mounting position, and the squeegee 30 is mounted on the holder 112. Further, the engagement between the regulating member 26 and the protruding portion 34 is released. Then, the print control unit 11 moves the squeegee fixing unit 24 rearward. When the second squeegee 30b is delivered to the holder 112 on the rear side of the squeegee transfer jig 110, the print control unit 11 may perform an operation symmetrical with respect to the above operation.

The substrate support member replacement process in step S140 will be described. When the board support member replacement process is started, the print control unit 11 performs a board support member carry-out process for carrying out the board support member 70 and a board support member carry-in process for carrying in the replacement board support member 70. 18 and 19 are explanatory views of the substrate support member carry-out process. In the substrate support member carry-out process, the print control unit 11 first receives a support member transfer jig in which at least one of the first and second protrusion holding portions 132 and 133 and the third and fourth protrusion holding portions 134 and 135 is vacant. The conveyor elevating portion 105 is operated so that the conveyor 104 (here, the eighth conveyor 104h) on which the tool 130 is placed and the conveyor rail 53 have the same height (delivery height). That is, the print control unit 11 positions the eighth conveyor 104h at the same height as the carry-out height of the screen mask 55 described above. Next, the print control unit 11 controls the eighth conveyor 104h and the transfer rod 38 to carry the support member transfer jig 130 into the printing device 10 (FIG. 18A). In the print control unit 11, the protrusion holding portions (here, the third and fourth protrusion holding portions 134 and 135) to which the substrate support member 70 is attached are located in the front-rear direction (here) from directly above the protrusions 71 and 72 of the substrate support member 70. Then, the support member transfer jig 130 is conveyed so as to be displaced to the rear). Subsequently, the print control unit 11 separates the pair of side frames 60b and 60b back and forth by the board guide moving unit 63, and controls the support base elevating part 65 and the fixed part elevating part 66 to raise the board support member 70. (Fig. 18B). As a result, the protrusions 71 and 72 of the substrate support member 70 rise above the first to fourth protrusion holding portions 132 to 135. The position of the substrate support member 70 at this time is the delivery position of the substrate support member 70. Subsequently, the print control unit 11 moves the support member transfer jig 130 forward by the transfer rod 38, and the third and fourth protrusion holding portions 134 and 135 are directly below the protrusions 71 and 72 of the substrate support member 70. Is located (Fig. 18C). Then, the print control unit 11 lowers the support base 67. As a result, the substrate support member 70 is in a state where the protrusions 71 and 72 are engaged with the third and fourth protrusion holding portions 134 and 135 and are attached to the support member transfer jig 130 (FIG. 19A). After that, the print control unit 11 lowers the entire substrate fixing portion 60 and conveys the support member transfer jig 130 to which the substrate support member 70 is attached forward by the transfer rod 38 to bring the support member transfer jig 130. Carry out (Fig. 19B). Further, the print control unit 11 further forwards the support member transfer jig 130 by the eighth transfer conveyor 104h, and stores the support member transfer jig 130 in the storage unit 102. The print control unit 11 may perform the next board support member carry-in process as it is without lowering the board fixing unit 60.

The print control unit 11 can perform the board support member carry-in process in the reverse procedure of the board support member carry-out process described above. In the substrate support member carry-in process, in the print control unit 11, first, the ninth conveyor 104i on which the support member transfer jig 130 to which the replacement substrate support member 70 is attached is placed and the transfer rail 53 are at the same height. The conveyor elevating part 105 is operated so as to reach (carry-in height). Next, the print control unit 11 carries in the support member transfer jig 130 by the ninth transfer conveyor 104i and the transfer rod 38, and conveys the replacement substrate support member 70 to the upper part of the support base 67. Subsequently, the print control unit 11 raises the support base 67 to raise the substrate support member 70, and the protrusions 71 and 72 and the protrusion holding portions (here, the third and fourth protrusion holding portions 134 and 135) are formed. Disengage. The position of the substrate support member 70 at this time is the receiving position of the substrate support member 70. After that, the print control unit 11 moves the support member transport jig 130 forward or backward to shift the positions of the protrusions 71 and 72 and the third and fourth protrusion holding portions 134 and 135 back and forth, and then supports the support member 11. Lower the table 67. Then, the print control unit 11 lowers the entire substrate fixing portion 60, transports the support member transport jig 130 forward by the transport rod 38, and carries out the support member transport jig 130. In addition, the print control unit 11 further forwards the support member transfer jig 130 by the ninth transfer conveyor 104i, and stores the support member transfer jig 130 in the storage unit 102.

The mask carry-in process in step S150 will be described. The print control unit 11 can perform the mask loading process in the reverse procedure of the mask loading process described above. In the mask carry-in process, the print control unit 11 first positions the conveyor 104 (here, the seventh conveyor 104 g) at the height (carry-in height) for carrying in the replacement screen mask 55. The conveyor elevating part 105 is operated. The carry-in height of the screen mask 55 is the same as the carry-in height of the screen mask 55. Next, the print control unit 11 conveys the replacement screen mask 55 to the rear by the seventh conveyor 104 g and the conveyor rod 38, and carries in the replacement screen mask 55. When the above steps S100 to S150 are performed, the print control unit 11 ends the exchange processing routine.

The printing apparatus 10 of the present embodiment described in detail above includes a cartridge 49, a squeegee 30, a cleaning member 82, a screen mask 55, and a substrate support member 70, of which the cartridge 49, the squeegee 30, and the cleaning member 82. For each of the replaceable members 13 including two or more types including at least one type (all five types in this embodiment), at least movement of the replaceable member 13 to the exchange position and loading / unloading of the replaceable member 13 are performed. It has a moving part that does one. More specifically, the moving unit includes a printing moving unit 22 and a supply moving unit 46 that move the cartridge 49 to the exchange position and carry in / out the cartridge 49, and a printing moving unit 22 and a printing moving unit 22 that move the squeegee 30 to the exchange position. A squeegee elevating part 23, a printing moving part 22 for carrying in and out the squeegee 30, a transfer rod 38, and a transfer rail 53 are provided. Further, the moving unit includes a cleaning moving unit 87 that moves the cleaning member 82 to the replacement position and carries in / out the cleaning member 82, and a printing moving unit 22, a transport rod 38, and a transport rail 53 that carry in / out the screen mask 55. The support base elevating part 65 and the fixed part elevating part 66 for moving the board support member 70 to the replacement position, and the printing moving part 22, the transfer rod 38, and the transfer rail 53 for carrying in and out the board support member 70. , Is equipped. Then, the printing device 10 includes a printing control unit 11 that controls the moving unit and executes an exchange process for exchanging the replaceable member 13. Therefore, the printing apparatus 10 can automatically replace two or more types (five types in this embodiment) of the replaceable members 13.

Further, in the printing device 10, the moving unit has a common moving mechanism for moving two or more kinds of members included in the replaceable member 13. Specifically, the print moving unit 22 is a moving mechanism common to moving the cartridge 49, the squeegee 30, the screen mask 55, and the substrate support member 70. The transfer rod 38 and the transfer rail 53 are moving mechanisms common to the movement of the squeegee 30, the screen mask 55, and the substrate support member 70. Therefore, the printing device 10 can automatically replace each of two or more types of replaceable members 13 by using the same moving mechanism. Therefore, the printing device 10 can be made more compact than the case where the printing device 10 is provided with a separate moving mechanism for each type of the replaceable member 13, for example.

Further, the printing device 10 is common to two or more types of members included in the replaceable member 13, and is common to the member and at least one of the transfer jigs of the member (in the present embodiment, the screen mask 55 and each transfer jig 110). , 120, 130, and 140) are provided with a reading unit 97 that reads the barcodes 57a, 116, 126, 136, and 146. As a result, the printing device 10 can identify the replaceable member 13 by reading each barcode, so that the replacement process can be performed more appropriately. Further, since the printing device 10 performs the barcodes of each of the two or more types of members (all five types in the present embodiment) by the same reading unit 97, for example, the printing device 10 is different for each type of the replaceable member 13. The device configuration can be made compact as compared with the case where the reading unit is provided.

Furthermore, the printing device 10 can carry in and out the replaceable member 13 with and from the storage device 100 that stores the replaceable member 13, and the print control unit 11 has the replaceable member stored in the storage device 100. The reading unit 97 is made to read one or more kinds of identification information among the thirteenth items during the printing process. Therefore, the printing apparatus 10 can read one or more of the barcodes 57a, 116, 126, 136, and 146 of the replaceable member 13 in advance before the replacement process. Therefore, the printing apparatus 10 can perform the exchange process in a shorter time than the case where all the barcodes are read during the exchange process.

Furthermore, when the print control unit 11 causes the reading unit 97 to read one or more barcodes of the replaceable member 13, the position where the reading unit 97 can read the replaceable member 13 stored in the storage device 100. A command is output to the storage device 100 so as to move to. Therefore, even if the reading unit 97 cannot read the barcodes 57a, 116, 126, 136, and 146 while being stored in the storage device 100, the print control unit 11 moves the replaceable member 13 to the storage device 100. As a result, the reading unit 97 can read the respective barcodes 57a, 116, 126, 136, and 146. Further, since the barcode is read during the printing process, even if the storage device 100 moves the replaceable member 13 for reading, the effect on the time required for the replacement process is small.

Further, the storage device 100 is one or more of the storage unit 102 that stores the above-mentioned replaceable member 13 and the exchangeable member 13 between the storage unit 102 and the printing device 10 (in this embodiment, the squeegee 30 and It is provided with a conveyor 104 for carrying in and out the screen mask 55 and the substrate support member 70). Therefore, since the printing device 10 only needs to deliver the replaceable member 13 to and from the storage device 100 instead of the operator, the printing device 10 can easily perform automatic replacement of the replaceable member 13. Further, the print control unit 11 carries in and out the cartridge 49 and the replacement module 81, which are not carried in and out by the conveyor 104, by the mechanism on the printing device 10 side.

Further, the storage device 100 includes a conveyor elevating unit 105 that raises and lowers the storage unit 102, and the storage unit 102 includes a storage area 103 that stores at least one type of replaceable member 13 (all five types in this embodiment). It has 9 steps in the vertical direction. Therefore, since each of the plurality of storage areas 103a to 103i can store the replaceable member 13, the storage unit 102 can easily store two or more types of replaceable members 13. Further, since the conveyor elevating part 105 can adjust the height of the replaceable member 13 when the replaceable member 13 is delivered to and from the printing device 10, the storage device 100 can be used for each printing device 10 or the replaceable member 13. The replaceable member 13 can be delivered at an appropriate height for each type of.

Further, the storage unit 102 stores the replaceable member 13 (here, the cartridge 49) having the highest carry-in height to the printing device 10 among the replaceable members 13 in the first storage area 103 of the plurality of stages. It is stored in the area 103a. Therefore, for example, as compared with the case where the cartridge 49 having the highest carry-in height is stored in a place other than the first storage area 103a on the uppermost stage, it is easy to reduce the elevating range required for the conveyor elevating portion 105.

Further, the storage unit 102 stores the replacement module 81 including the cleaning member 82 in a state of being attached to the protrusion holding portion 142 of the cleaning member transport jig 140, and the conveyor elevating unit 105 stores the cleaning member by raising and lowering the storage unit 102. By raising and lowering the transfer jig 140, the replacement module 81 received (delivered) from the printing device 10 is attached to the cleaning member transfer jig 140. Further, the conveyor elevating unit 105 prints by removing the replacement module 81 attached to the cleaning member transport jig 140 from the cleaning member transport jig 140 by raising and lowering the cleaning member transport jig 140 by raising and lowering the storage portion 102. Hand over to device 10. Therefore, the conveyor elevating unit 105 can also serve as a mechanism for transferring the exchange module 81 between the storage device 100 and the printing device 10.

It is needless to say that the present invention is not limited to the above-described embodiment, and can be implemented in various aspects as long as it belongs to the technical scope of the present invention.

For example, in the above-described embodiment, the storage unit 102 stores the cartridge 49 having the highest carry-in height to the printing device 10 among the replaceable members 13 in the first storage area 103a on the uppermost stage. Not limited. Further, the storage unit 102 may store the member having the lowest carry-in height to the printing device 10 among the replaceable members 13 in the lowest stage of the plurality of stages of the storage areas. For example, the cleaning member 82 may be stored in the ninth storage area 103i on the ninth conveyor 104i.

In the above-described embodiment, the print control unit 11 performs the reading process during the printing process, but the present invention is not limited to this. For example, the print control unit 11 may first perform a reading process before steps S100 to S150 when executing the replacement process of FIG. 11. Alternatively, instead of performing the reading process, the print control unit 11 inputs information on the replaceable member 13 and the transfer jig stored in the storage unit 102 from the management PC 150, or the operator via the display operation unit 98. You may enter it. Further, a rule for which of the empty transport jigs to be stored in which storage area 103 is predetermined, or which type of replaceable member 13 is stored in which storage area 103. The rules may be predetermined. In this case, if the print control unit 11 stores the rule in advance and the operator stores the transfer jig and the replaceable member 13 in the storage area 103 according to the rule, the print control unit 11 does not perform the reading process. You may.

In the above-described embodiment, the printing device 10 is provided with the reading unit 97, but the present invention is not limited to this, and the storage device 100 may be provided with the reading unit 97, for example. In this case, the storage control unit 106 may perform the above-mentioned reading process instead of the print control unit 11 and output the acquired information to the print control unit 11. Also in this case, the storage control unit 106 can perform the reading process without stopping the printing process by the print control unit 11.

In the above-described embodiment, the transfer jig has a bar code attached to the replaceable member 13 transported by the transfer jig, but the present invention is not limited to this, and the replaceable member 13 may have a bar code attached. .. Further, in the above-described embodiment, the bar code is attached to the transfer jig and the screen mask 55, but the bar code is not limited to the bar code, and a two-dimensional code or the like may be attached.

In the above-described embodiment, the printing device 10 has a print moving unit 22 as a moving mechanism common to the movement of four of the five types of replaceable members 13, but the movement is not limited to this, and all five types of movement are not limited to this. May have a common movement mechanism. For example, the mounting member moving mechanism 89 switches between the protruding state and the non-protruding state of the replacement module 81 and the mounting member 84, and the transport rod 38 may perform this switching. For example, the transport rod 38 may be configured to project downward to the same height as the replacement module 81, and the transport rod 38 may be moved back and forth by the print moving unit 22 to switch between the protruding state and the non-protruding state. In this case, the print moving unit 22 serves as a moving mechanism common to all five types of replaceable members 13. Further, the printing device 10 has a moving mechanism common to the movement of two or more types of members including the squeegee 30 among the squeegee 30, the screen mask 55 and the substrate support member 70 (for example, the printing moving portion 22, the transport rod 38 and the transport rail 53). ) May have. Alternatively, the printing device 10 has a moving mechanism common to the movement of two or more types of members including at least one of the squeegee 30, the screen mask 55, the substrate support member 70, and the cleaning member 82 (for example, the squeegee 30 and the cleaning member 82). It may have a print moving portion 22 and a transport rod 38).

In the above-described embodiment, the print control unit 11 performs the mask carry-out process before performing the squeegee exchange process in the exchange process routine, but the present invention is not limited to this. For example, if the squeegee transfer jig 110 and the squeegee fixing portion 24 can deliver the squeegee 30 in the area in front of the screen mask 55 without retracting the screen mask 55, the print control unit 11 may transfer the squeegee. It is not necessary to carry out the mask removal process before the replacement process.

Although not particularly described in the above-described embodiment, the print control unit 11 has all the necessary replacement replaceable members 13 in the storage device 100 based on the information acquired in the reading process at the start of the replacement process routine. It may be determined whether or not it is stored. Then, when the print control unit 11 determines that the necessary replacement replaceable member 13 is not housed, the print control unit 11 outputs error information indicating that fact to at least one of the display operation unit 98 and the management PC 150. The operator may be notified that the replaceable member 13 is insufficient. When the print control unit 11 determines that the necessary replacement replaceable member 13 is not housed, the print control unit 11 may perform a replacement process for the replaceable member 13 of a type other than the replaceable member 13. For example, even if the replacement cartridge 49 is not stored in the storage device 100, the print control unit 11 replaces any of the other four types of replaceable members 13 when it is necessary to replace them. The process may be executed. In this way, it is possible to perform the replacement process of the other replaceable member 13 while the operator prepares the shortage of replaceable member 13.

In the above-described embodiment, the storage device 100 includes the storage control unit 106, and the print control unit 11 indirectly controls the storage device 100 by outputting a command to the storage control unit 106, but the present invention is not limited to this. The storage control unit 106 may be omitted. In this case, for example, the print control unit 11 may directly control the conveyor 104 and the conveyor elevating unit 105 by communication.

In the above-described embodiment, the storage device 100 is provided with a moving portion and can be moved by an operator, but the present invention is not limited to this, and the moving portion may not be provided. Further, the storage device 100 may be configured as a self-propellable AGV (Automatic Guided vehicle) having a drive mechanism for driving the moving portion. In this case, the storage device 100 may move to the place where the replacement replaceable member 13 is stored, and the replacement replaceable member 13 may be automatically stored in the storage unit 102.

In the above-described embodiment, the replacement of the replaceable member 13 when the setup is changed has been mainly described, but the replacement timing is not limited to this. For example, with respect to consumables such as the cartridge 49 and the cleaning member 82, the print control unit 11 may replace the consumables, for example, when the sensor that detects the remaining amount detects that the consumables have run out.

In the above-described embodiment, the printing device 10 automatically replaces all five types of replaceable members 13 with the storage device 100, but is not limited thereto. For example, for one or more of the replaceable members 13, the printing apparatus 10 itself may have two or more holders to which the replaceable replaceable member 13 can be attached. In this case, if the operator attaches the replaceable member 13 for replacement to at least one holder and leaves at least one holder empty, the printing device 10 can automatically replace the holder with the holder. it can. In this way, the printing apparatus 10 may perform an exchange process for one or more of the exchangeable members 13 without carrying in and out.

In the above-described embodiment, in the storage device 100, all the replaceable members 13 other than the screen mask 55 are stored in the storage unit 102 in a state of being attached to the transfer jig, but are stored in a state of being attached to the holder. You just have to. For example, the storage device 100 may store one or more types of replaceable members 13 other than the screen mask 55 in a state of being attached to a holder that cannot be conveyed by the transfer conveyor 104. Even in this way, if the printing device 10 has a mechanism for delivering the replaceable member 13 to and from the storage device 100, automatic replacement can be performed as in the above-described embodiment. For example, in the storage device 100 of the above-described embodiment, since the cartridge 49 and the replacement module 81 can be automatically replaced without the storage device 100 transporting the cartridge 49 and the replacement module 81 back and forth, at least one of the cartridge 49 and the replacement module 81 can be replaced. It may be attached to a fixed holder instead of a transport jig.

In the above-described embodiment, the printing apparatus 10 is configured to be capable of automatically replacing all five types of replaceable members 13, but the present invention is not limited to this, and one type including at least one type other than the screen mask 55. The replaceable member 13 may be configured to be automatically replaced. Further, when the printing device 10 can automatically replace 2 to 4 types of the 5 types of replaceable members 13, any combination of the 5 types of the automatically replaceable replaceable members 13 may be selected. .. Further, one or more and four or less of the five types of replaceable members 13 may be configured so as not to be replaced by an operator (that is, they are not replaceable members). Further, the printing device 10 does not have to include one or more of the five types of replaceable members 13. For example, the printing device 10 does not have to include a cleaning unit 80 including a cleaning member 82.

The printing device and the storage device of the present disclosure may be configured as follows.

In the printing apparatus of the present disclosure, the moving unit may have a common moving mechanism for moving two or more kinds of members included in the replaceable member. In this way, the printing apparatus can automatically replace each of two or more kinds of replaceable members by using the same moving mechanism. Therefore, this printing device can make the device configuration more compact than, for example, as compared with the case where the printing device is provided with a separate moving mechanism for each type of replaceable member.

The printing apparatus of the present disclosure includes a reading unit that reads identification information attached to at least one of the member and a transfer jig of the member, which is common to two or more kinds of members included in the replaceable member. May be good. In this way, the printing device can identify the replaceable member by reading the identification information, so that the replacement process can be performed more appropriately. Further, since this printing device reads the identification information of each of the two or more types of members with the same reading unit, the device configuration is compared with the case where the printing device is provided with a separate reading unit for each type of replaceable member, for example. Can be made compact.

In this case, the printing device can carry in and out the replaceable member to and from the storage device that stores the replaceable member, and the exchange control unit is the replaceable that is housed in the storage device. The reading unit may read the identification information of one or more kinds of the members during the printing process. In this way, the printing apparatus can read the identification information of one or more kinds of the replaceable members in advance before the replacement process. Therefore, this printing apparatus can perform the replacement process in a shorter time than, for example, when reading the identification information of all the replaceable members during the replacement process.

In this case, the exchange control unit reads the replaceable member housed in the storage device when the reading unit reads the identification information of one or more of the replaceable members during the printing process. A command may be output to the storage device so that the unit is moved to a readable position. In this way, even if the reading unit cannot read the identification information while it is stored in the storage device, the replacement control unit moves the replaceable member to the storage device so that the reading unit can read the identification information. Further, since the identification information is read during the printing process, even if the storage device moves the replaceable member for reading, the time required for the replacement process is less affected.

The replaceable member can be delivered at.

In this case, the storage unit either stores the member having the highest carry-in height to the printing device among the replaceable members in the uppermost stage of the plurality of stages of the storage areas, or the replaceable member. The member having the lowest carry-in height to the printing apparatus may be stored in the lowest stage of the plurality of stages of the storage area, or at least one of them may be stored. In this way, for example, when the member having the highest carry-in height is stored in the uppermost stage of the storage areas of the plurality of stages, the elevating range required for the elevating part is compared with the case where the member is stored in other than the uppermost stage. Easy to make small. Similarly, for example, when a member having the lowest carry-in height is stored in the lowest stage of a plurality of storage areas, the elevating range required for the elevating part is increased as compared with the case where the member is stored in a storage area other than the lowest stage. Easy to make small.

The storage device of the present disclosure includes an elevating unit that raises and lowers the storage unit, and the storage unit stores one or more of the replaceable members in a state of being attached to a holder.
