The plurality of protrusions 83d function as an engaging portion that engages with the protrusion holding portion 142 of the cleaning member conveyance jig 140 shown in FIG. On the front surface of the box body 83a, receiving members 83e are provided at both left and right ends. The receiving member 83e has a recess that opens toward the left and right outer sides, and is configured to engage with the locking member 86d of the locking mechanism 86c in the non-projecting state. Openings 83f are formed on the left and right side surfaces of the box 83a, and an engagement shaft 83g extending in the Y direction is disposed within the openings 83f. The engagement shaft 83g is configured to engage with a claw member 84c of the mounting member 84 (enlarged view in the upper right corner of FIG. 8).

The mounting member 84 is configured as a plate-shaped member on which the replacement module 81 is placed 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 section 87. A contact member 84a, a lifting device 84b, a claw member 84c, and a connecting portion 84d are disposed 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 lifting device 84b is configured as, for example, an air cylinder, and lifts and lowers the contact member 84a while supporting it from below. When the lifting 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 can be brought 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 members 84c are members 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 one claw member 84c is provided on each side of the mounting member 84. ing. The claw member 84c is a substantially quadrangular prism-shaped member whose longitudinal direction is along the up-down direction. The claw member 84c has an inclined surface on the inside of the upper end in the left-right direction (inside the mounting member 83), and a recessed portion that engages with the engagement shaft 83g of the mounting member 83 is formed below the inclined surface. The claw member 84c is disposed near the lower end and is rotatably supported around a rotation axis along the Y direction, and the upper end of the claw member 84c is rotated inward in the left-right direction by an elastic member such as a spring (not shown). biased in the direction. As a result, when the replacement module 81 descends from above the mounting member 84, the engagement shaft 83g of the mounting member 83 of the replacement module 81 is guided by the inclined surface of the claw member 84c and engages with the recess of the claw member 84c. When engaged, relative movement of the mounting member 83 and mounting member 84 in the Y direction is restricted. Note that when the replacement module 81 attempts to move upward from the mounting member 84, the elastic force of the elastic member that biases the claw member 84c is increased so that the engagement between the engagement 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 disposed 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. Thereby, the support member 86 supports the mounting member 84 from the left and right directions along the horizontal direction. The support member 86 is provided with a take-up motor 86a and a lock mechanism 86c. The take-up motor 86a is disposed on the right side of the attachment member 83 in the support member 86, and rotates the gear 83c and the second roller 81b via the gear 86b. The cleaning section 80 cleans the part of the cleaning member 82 that has been cleaned, that is, the part to which solder has adhered, by having the take-up motor 86a rotate the second roller 81b during a certain period of time after the cleaning process, for example. A sheet feeding process is performed to feed the sheet into the second roller 81b. The lock mechanism 86c is configured as, for example, an air cylinder, and is a mechanism that causes the lock member 86d to protrude in the X direction via the cylinder. One locking mechanism 86c is disposed on each side of the mounting member 83 of the support member 86 on the left and right sides. As shown in FIG. 9, when the locking mechanism 86c causes the locking member 86d to protrude toward the mounting member 83 when the replacement module 81 and the mounting member 84 are in the non-protruding state, the locking member 86d moves toward the mounting member 83. It is inserted into the recess of the receiving member 83e and the two are engaged. 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 locking mechanism 86c does not allow the locking member 86d to protrude, the replacement module 81 and the mounting member 84 can be switched between the protruding state and the non-protruding state by the mounting member moving mechanism 89.

The cleaning moving unit 87 includes a support member moving mechanism 88 and a mounting member moving mechanism 89. As shown in FIG. 1, the support member moving mechanism 88 includes a Y-axis slider 88a and a pair of left and right guide rails 88b extending in the front-rear direction. The Y-axis slider 88a is disposed on the support member 86, and as the Y-axis slider 88a moves along the guide rail 88b, the support member 86 is moved in the Y direction. By moving the support member 86 in the Y direction, the support member moving mechanism 88 also moves the replacement module 81 and the mounting member 84 in the Y direction. As shown in FIGS. 8 and 9, the mounting member moving mechanism 89 includes a drive source 89a configured as an air cylinder, for example, and a connecting portion of the mounting member 84 disposed at the tip of a cylinder rod of the drive source 89a. 84d and a connecting portion 89b connected to the connecting portion 84d. Further, the placement member moving mechanism 89 includes an extendable rail 89c that is disposed on the support member 86 and includes a plurality of rails that slide in the Y direction. When the driving force in the Y direction from the drive source 89a acts on the mounting member 84 through the connecting portion 89b and the connecting portion 84d, the telescopic rail 89c expands and contracts, so that the mounting member 84 is moved in the Y direction relative to the supporting member 86. Move relative to the direction. As a result, the mounting member moving mechanism 89 can be placed in the protruding state (FIG. 8) in which the exchange module 81 and the mounting member 84 are projected forward relative to the support member 86, and in the protruding state (FIG. 8) in which the exchange module 81 and the mounting member 84 are It is possible to switch between a non-projecting state (FIG. 9) in which the support member 86 is not projected forward relative to the support member 86. The cleaning moving unit 87 moves the cleaning member 82 between the cleaning position where the cleaning member 82 cleans the screen mask 55 and the cleaning member conveying jig 140 using the supporting member moving mechanism 88 and the placement member moving mechanism 89. to exchange between the exchange positions. Note that the cleaning position is, for example, a position directly below the screen mask 55 fixed to the mask fixing part 51. The exchange position is, for example, a position where the exchange module 81 is transferred between the cleaning member conveyance jig 140 and the cleaning section 80. Further, the cleaning moving unit 87 carries in and out the cleaning member 82 and the replacement module 81 including the same.

The cleaning member conveyance jig 140 shown in FIG. 8 serves as a holder to which the exchange module 81 is attached. The cleaning member conveying jig 140 includes a frame-shaped frame 141 with an open rear side, a protrusion holding part 142 disposed inside the frame 141 in the left-right direction, and a protrusion holding part 142 disposed near the rear end of the right side of the frame 141. A barcode 146 is provided. The same number (here, three) of the protrusion holding parts 142 are provided corresponding to the protrusion parts 83d of the mounting member 83. More specifically, one protrusion holding part 142 is disposed on the right side, and two protrusion holding parts 142 are disposed on the left side. The protrusion holding part 142 has a recess formed in its upper surface, and engages with the protrusion 83d placed in the recess to support the protrusion 83d from below. By engaging the protrusion 83d with this recess, the cleaning member conveyance jig 140 can convey the exchange module 81 while fixing the relative position of the exchange module 81 in the front-rear direction. The barcode 146 is identification information for identifying the cleaning member 82 attached to the cleaning member conveyance jig 140, and is attached in advance by, for example, an operator.

The reading unit 97 is a device that reads information regarding one or more of the replaceable members 13, and is configured as a barcode reader in this embodiment. As shown in FIG. 1, the reading unit 97 is arranged at the front right inside the printing device 10, and the reading direction is toward the left. The reading unit 97 is arranged at the same height as the height at which the screen mask 55 is carried in and out (the carrying-in height and the carrying-out height), and reads the barcode 57a attached to the right side of the screen mask 55 (Fig. ) 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. can.

The storage device 100 is disposed in front of the printing device 10, stores one or more types (five types in this case) of replaceable members 13, and exchanges one type of the replaceable members 13 with the printing device 10. This is a device that carries out the above (five types in this case) loading/unloading. The storage device 100 includes a housing 101 , a storage section 102 , a conveyor 104 , a conveyor elevating section 105 , and a storage control section 106 . The housing 101 is a substantially rectangular parallelepiped box and has a storage section 102 inside. A moving part such as casters is provided on the lower surface of the housing 101, so that, for example, an operator can move the storage device 100. The storage section 102 is a box that can store the replaceable member 13 and the conveyance jig, and a plurality of conveyors 104 are arranged inside. The transport conveyors 104 are arranged in a plurality of stages in the vertical direction, and in this embodiment, as shown in FIG. 2, first to ninth transport conveyors 104a to 104i are arranged in order from the top. 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-back direction. Note that, in FIG. 1, only four stages of the conveyor 104 are shown for convenience of illustration. The storage section 102 is configured to be able to place at least one replaceable member 13 on each of the first to ninth conveyors 104a to 104i. Furthermore, the storage section 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 transport conveyor 104a, and similarly has second to ninth storage areas 103a as areas above each of the second to ninth transport conveyors 104b to 104i. It has ninth storage areas 103b to 103i. Note that the storage area 103 does not necessarily need to be inside the storage section 102. For example, a part of the cartridge transport jig 120 placed on the first transport conveyor 104a shown in FIG. It will be done. The storage section 102 is open at the front and back. This allows the operator to insert the replaceable member 13 into the storage section 102 from the front, and the storage device 100 to carry the replaceable member 13 into and out of the printing device 10 through the rear of the storage section 102. . The conveyor elevating section 105 is a mechanism for elevating the storage section 102 up and down, and includes, for example, a guide, a ball screw, and a drive motor (not shown). The conveyor 104 is raised and lowered by the conveyor lifting section 105 raising and lowering the storage section 102 .

In this embodiment, a cartridge conveyance jig 120 is placed on the first conveyor 104a, a squeegee conveyance jig 110 is placed on the second and third conveyors 104b and 104c, and a fourth and fifth conveyor A cleaning member conveyance jig 140 is placed on the conveyors 104d and 104e, a screen mask 55 is placed on the sixth and seventh conveyors 104f and 104g, and a cleaning member conveyor jig 140 is placed on the sixth and seventh conveyors 104f and 104g. A support member conveyance jig 130 is placed on top. The distance between vertically adjacent conveyors 104 is adjusted according to the height of the conveyance jig placed on each conveyor 104 and the replaceable member 13 attached to the conveyance jig. Note that the width of each of the transport jigs 110 to 140 and the screen mask 55 in the left and right directions is determined so that they can be placed on any of the plurality of transport conveyors 104, and for example, the widths in the left and right directions are approximately the same. It has become.

The storage control unit 106 is configured as a microprocessor centered on a CPU, and includes a ROM that stores processing programs, a RAM that is used as a work area, and an HDD that stores various data. The storage control unit 106 controls the storage device 100 as a whole.

Next, the operation of the printing system 1 configured in this way will be explained. First, the printing process executed by the printing device 10 and the reading process of 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 printing processing and reading processing are performed in parallel.

First, print processing will be explained. The print processing routine for performing the print processing is stored in the HDD of the print control unit 11, and is executed after the print control unit 11 receives an instruction from the operator to execute the print processing via the display operation unit 98, or after the print control unit 11 inputs an instruction to execute the print processing from the operator via the display operation unit 98. 11 inputs a print processing execution command from the management PC 150, the print processing is executed. When the print processing routine is started, the print control section 11 first performs a substrate transport and fixing process in which the substrate S is fixed by the substrate fixing section 60 and brought into contact with the screen mask 55, as shown in FIG. Specifically, the print control section 11 first drives the substrate conveyor 61 to convey the substrate S to the substrate fixing section 60, and then clamps and fixes the substrate S between the substrate guides 62. Further, the print control unit 11 adjusts the position of the screen mask 55 using the mask working unit 50 as necessary to align the pattern holes 58 and the substrate S. Next, the print control unit 11 raises the support stand 67 to bring the upper surface of the substrate support member 70 into contact with the lower surface of the substrate S, and fixes the substrate S to the substrate support member 70 by suction using negative pressure from the pressure reducing device. do. Then, the print control section 11 raises the substrate fixing section 60 to bring the upper surface of the substrate S into contact with the lower surface of the screen mask 55. After performing the substrate transport and fixing process, the print control unit 11 performs the solder supply process. Specifically, the print control unit 11 moves the supply head 41 above the screen mask 55, supplies air from the air supply unit 42, and discharges solder from the cartridge 49 onto the screen mask 55. After performing the solder supply process, the print control unit 11 performs a squeegee movement process. Specifically, the print control unit 11 moves the print head 21 and lowers the squeegee 30 (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 the solder in the direction shown in FIG. The print control unit 11 performs at least one of moving the first squeegee 30a backward and moving the second squeegee 30b forward on the screen mask 55. In this way, the print control unit 11 prints on the substrate S by performing a printing process including a substrate transport and fixing process, a solder supply process, and a squeegee movement process. The print control unit 11 repeatedly performs this printing process until the production process is completed. Note that the printing process may include the above-mentioned cleaning process and sheet feeding process. The print control unit 11 performs a cleaning process and a sheet feeding process to clean the back surface of the screen mask 55 at a predetermined timing such as every predetermined time period or every time a predetermined number of substrates S are printed.

While the printing device 10 is performing this printing process, the operator places replacement parts in the storage device 100 in advance in case one or more of the replaceable members 13 needs to be replaced, for example due to setup changes. The replaceable member 13 is stored. For example, if it is necessary to replace all of the five types of replaceable members 13 at the time of the next setup change, the operator will store each transport jig and the replaceable members attached to it in the storage device 100 as shown in FIG. The member 13 is stored. Specifically, as shown in FIG. 2, the operator stores the cartridge transport jig 120 with the replacement cartridge 49 attached to the holder 122 in the first storage area 103a. At this time, the operator leaves at least one of the plurality of holders 122 of the cartridge transport jig 120 in an empty state, as shown in FIG. The operator stores the empty squeegee transport jig 110 in the second storage area 103b, and stores the squeegee transport jig 110 with two replacement squeegees 30 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 with the replacement module 81 attached in the fifth storage area 103e. The operator leaves the sixth storage area 103f open for carrying out the screen mask 55 in use from the printing apparatus 10, and stores the replacement screen mask 55 in the seventh storage area 103g. The operator stores the empty support member transport jig 130 in the eighth storage area 103h, and stores the support member transport jig 130 with one replacement board support member 70 attached in the ninth storage area 103i. . In this way, the operator can store the replaceable member 13 in advance in the storage device while the printing device 10 is performing printing processing, rather than when the replaceable member 13 needs to be replaced such as during setup change. It is sufficient to store it in 100. Therefore, the worker can prepare the replaceable member 13 for replacement during a time period when the workload is light.

Note that the operator attaches a bar code to each transport jig in advance, which represents identification information of the replaceable member 13 attached to the transport jig. For example, the operator makes sure that the identification information included in the barcode 126 of the cartridge transport jig 120 includes information indicating the type of the cartridge 49 attached to the cartridge transport jig 120. Similarly, the operator makes sure that the identification information included in the barcode 57a of the screen mask 55 includes information indicating the type of the screen mask 55. In this way, the printing control unit 11 allows the reading unit 97 to read the barcodes of each conveyance jig and screen mask 55, thereby determining which of the five types of replaceable members 13 the barcodes relate to. can be identified. Further, the print control unit 11 identifies detailed types among the replaceable members 13 of the same type, such as which type of cartridge 49 is attached to the cartridge conveyance jig 120 among the plurality of types of cartridges 49, for example. You can also do that. Note that the barcode may also include information indicating the status of each transport jig (such as whether or not the holder is empty). For example, the barcode 126 of the cartridge transport jig 120 includes information on which of the plurality of holders 122 of the cartridge transport jig 120 the cartridge 49 is attached to (which holder 122 is empty). You can leave it there.

Next, the reading process will be explained. A reading process 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 period or after an operator inputs an instruction to execute the reading process. When the reading processing routine is started, the print control unit 11 instructs the storage control unit 106 of the storage device 100 that the reading unit 97 can read the replaceable member 13 stored in the storage unit 102 or the empty conveyance jig. A command is output to move the robot to a certain position in sequence. Upon receiving this command, the storage control section 106 first raises and lowers the storage section 102 using the conveyor elevating section 105 so that the cartridge transport jig 120 on the first transport conveyor 104a is located at the same height as the reading section 97. Further, the storage control unit 106 transports the cartridge transport jig 120 in the Y direction by the first transport conveyor 104a as needed to move the barcode 126 to a position where the reading unit 97 can read it, and then transports the cartridge. The jig 120 is transported 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 obtained information in the HDD. The storage control unit 106 sequentially performs similar processing for the second conveyor 104b to the ninth conveyor 104i. FIG. 10 shows a state in which the storage device 100 has transported the squeegee transport jig 110 stored in the second storage area 103b to a position where the reading section 97 can read it. In this way, in the reading process, the print control unit 11 causes the storage device 100 to at least one of transport and raise/lower the replaceable member 13 to move it to a position where the reading unit 97 can read it. Through this reading process, the print control unit 11 can obtain information about the replaceable members 13 stored in each of the storage areas 103 of the storage device 100, and which type of transport jig is stored in each of the storage areas 103. Acquires and stores information necessary for the exchange process described later. In addition, the print control unit 11 detects that the reading unit 97 does not read information for a predetermined period of time even when the conveyance jig is conveyed by the conveyor 104. It is also possible to specify the storage area 103 (sixth storage area 103f in FIG. 10). Note that, as shown in FIG. 10, the reading section 97 is disposed on the front side of the printing device 10. Therefore, even if the replaceable member 13 and the like are transported from the front storage device 100 to the reading position of the reading section 97, the print processing section 20, supply section 40, mask working section 50, substrate fixing section 60, etc. in the printing process described above, There is no problem in the operation of the cleaning section 80. Therefore, the print control unit 11 can perform the reading process in parallel with the printing process. Thereby, the print control unit 11 can acquire information about the replaceable member 13 and the transport jig stored in the storage device 100 without stopping the printing process.

Regarding the operation of the storage device 100 during the reading process, the operation routine during 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 a command to start the operation routine. It's okay. Alternatively, the printing control unit 11 may sequentially output individual operation commands for the conveyor elevating unit 105 and the transport 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 determines whether one or more types of replaceable members 13 necessary for the next print process are different from the current print process each time the print process is completed, based on information regarding the print process acquired from the management PC 150, for example. It is determined whether or not replacement processing is necessary. When the print control unit 11 determines that replacement processing is necessary, it starts a replacement processing routine. Note that the print control unit 11 performs the exchange processing routine while appropriately referring to the information acquired in the above-described reading process.

When the print control unit 11 starts the replacement processing routine, it performs cartridge replacement processing (step S100), cleaning member replacement processing (step S110), mask unloading processing (step S120), squeegee replacement processing (step S130), and substrate support member replacement processing. One or more of the processing (step S140) and the mask import processing (step S150) is performed as necessary. Note that since the cartridge 49 and the cleaning member 82 are consumables, not only when the type of each is changed, but also when it is necessary to perform a replacement process, at least one of the cartridge replacement process and the cleaning member replacement process may be combined. The consumables may be replenished without changing the type of consumables. For example, if one or more of the squeegee 30, screen mask 55, and substrate support member 70 needs to be replaced, at least one of the cartridge 49 and the cleaning member 82 may also be replaced. Furthermore, in this embodiment, when replacing the screen mask 55, squeegee 30, and substrate support member 70, the transport jig is transported using the transport rail 53 in all cases. 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 before these processes to evacuate the screen mask 55 from the transport rail 53, and these After the processing, a mask loading process is performed. Moreover, the process including the mask carry-out process and the mask carry-in process corresponds to the mask exchange process. Note that if there is no need to replace the screen mask 55, the screen mask 55 carried out in the mask carrying-out process is carried in in the mask carrying-in process. Hereinafter, each process of steps S100 to S150 will be explained using an example in which all five types of replaceable members 13 are replaced.

The cartridge replacement process in step S100 will be described. FIG. 12 is an explanatory diagram of the 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 unloading process for unloading the cartridge 49 attached to the supply head 41, and a cartridge loading process for loading the replacement cartridge 49. In the cartridge unloading process, the print control unit 11 first positions the cartridge transport jig 120 having the empty holder 122 on the first transport conveyor 104a at the height for transporting the cartridge 49 (unloading height). Then, the conveyor lifting section 105 is operated. The unloading height of the cartridge 49 is such that the cartridge 49 attached to the supply head 41 can be attached to the empty holder 122, and the height is such that the main body 49a can be inserted into the opening 124. . Next, the print control section 11 controls the print movement section 22 and the supply movement section 46 to move the cartridge 49 attached to the supply head 41 to a delivery position where it can be attached to an empty holder 122 of the cartridge transport jig 120. move it. Subsequently, the print control unit 11 releases the mounting of the cartridge 49 by the supply head 41 and attaches the cartridge 49 to the empty holder 122. In the cartridge loading process, the print control unit 11 first operates the conveyor lifting unit 105 so that the cartridge transport jig 120 is located at a height (carrying height) for loading the replacement cartridge 49. Note that 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 section 105 is omitted. Next, the print control unit 11 moves the supply head 41 to a receiving position where it can receive the replacement cartridge 49 attached to the holder 122, and attaches the replacement cartridge 49 to the supply head 41. After performing the cartridge unloading process and the cartridge loading process 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 then holds the clamp unit 43. Rotate to the release position. Then, as the clamp section 43 rotates, the cartridge 49 descends, and the cartridge 49 is supported by the support section 123 with the flange section 49b fitted into the engagement section 125. When attaching the replacement cartridge 49 to the supply head 41 in the cartridge loading process, the print control unit 11 first sets the connection part 49d of the replacement cartridge 49 directly below the air supply unit 42 (receiving position). An example of the position (FIG. 12A), the clamp portion 43 is rotated to the fixed position (FIG. 12B). When the clamp part 43 is located at the fixed position, the clamp part 43 pushes up the cartridge 49, releases the engagement between the flange part 49b and the engaging part 125, and positions the cartridge 49 in the detached position. At this time, the air supply section 42 is inserted into the connection section 49d, the cartridge 49 is positioned, and the supply head 41 becomes able to supply air to the main body section 49a. Then, the print control unit 11 moves the supply head 41 so that the main body 49a passes through the opening 124 (FIG. 12B).

The cleaning member replacement process in step S110 will be explained. When the cleaning member replacement process is started, the print control unit 11 performs a cleaning member unloading process for unloading the replacement module 81 and a cleaning member importing process for transporting the replacement module 81 for replacement. FIG. 13 is an explanatory diagram showing the state of the cleaning member carrying-out process. FIG. 14 is an explanatory diagram showing the state of the cleaning member import process. In the cleaning member carry-out process, the printing control unit 11 first operates the conveyor lifting unit 105 so that the empty cleaning member conveyance jig 140 is located at the height (carry-out height) for carrying out the replacement module 81. (Figure 13A). Here, the printing control unit 11 raises and lowers the fourth transport conveyor 104d on which the empty cleaning member transport jig 140 is placed to the unloading height. The height at which the exchange module 81 is carried out is such that the protrusion holding part 142 of the cleaning member conveying jig 140 is located below the protrusion 83d of the exchange module 81 attached to the mounting member 84. Furthermore, the printing control unit 11 controls the support member moving mechanism 88 to move the exchange module 81 to the front of the printing apparatus 10 (FIG. 13A). Note that the position of the exchange module 81 at this time may be, for example, a position at the front end of the area in which the exchange module 81 can be moved by the support member moving mechanism 88, or may be an initial position of the exchange module 81. Next, the print control unit 11 controls the placement member moving mechanism 89 to bring the placement member 84 into a protruding state, thereby moving the exchange module 81 to a delivery position where it can be attached to the cleaning member conveyance jig 140. (Figure 13B). In this embodiment, the delivery position is inside the storage unit 102, and the operation of the printing control unit 11 to move 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 exchange module 81 is located directly above each of the plurality of protrusion holding parts 142 of the cleaning member conveying jig 140. Subsequently, the printing control section 11 raises the storage section 102 using the conveyor lifting section 105. As a result, the protrusion holding portion 142 and the protrusion 83d engage, and the exchange module 81 is attached to the cleaning member conveyance jig 140 and ascends, and the exchange 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 conveyance jig 140. After that, the printing control unit 11 sets the mounting member 84 to a non-projecting state (FIG. 13D).

In the cleaning member loading process, the printing control unit 11 first moves the conveyor 104 above the height of the uppermost end of the mounting member 84 (here, the upper end of the abutting member 84a) in the protruding state (see FIG. 13C). The conveyor lifting section 105 is operated so that the replacement module 81 for replacement is located on the fifth conveyor 104e (here, the fifth conveyor 104e) (FIG. 14A). Next, the print control unit 11 controls the placement member moving mechanism 89 to bring the placement member 84 into a protruding state, thereby placing the exchange module 81 at a receiving position where it can be received from the cleaning member conveyance 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. Next, the storage unit 102 is lowered so that the cleaning member conveyance jig 140 on the fifth conveyor 104e is located at the height (carry-in height) for carrying in the replacement module 81, and then further lowered 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 conveyance jig 140 is further lowered to release the engagement between the protrusion holder 142 and the protrusion 83d. Note that the carrying-in height of the replacement module 81 is the height when the replacement module 81 for replacement is lowered and attached to the mounting member 84 . Then, the printing control unit 11 brings the exchange module 81 into the printing apparatus 10 by placing the placement member 84 in a non-protruding state (FIG. 14D). As described above, the exchange module 81 is received from the cleaning member conveying jig 140 and is carried into the printing apparatus 10. After performing the cleaning member carry-out process and the cleaning member carry-in process as described above, the print control unit 11 ends the cleaning member replacement process.

The mask carry-out process in step S120 will be explained. FIG. 15 is an explanatory diagram showing the state of the mask carry-out process. When the mask carry-out process is started, the print control unit 11 first locates an empty conveyor 104 (here, the sixth conveyor 104f) at a height for carrying out the screen mask 55 (carry-out height). The conveyor elevating section 105 is operated as follows. The unloading 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 causes the transport rod 38 to protrude downward and controls the print moving unit 22 to transport the screen mask 55 forward along the transport rail 53 (FIG. 15). Then, the printing control unit 11 causes the transport rod 38 to transport the screen mask 55 to the sixth transport conveyor 104f, and carries out the screen mask 55. Further, the print control unit 11 causes the sixth conveyor 104f to further convey the screen mask 55 forward, and stores the screen mask 55 in the storage unit 102. As a result, the screen mask 55 is removed from the transport rail 53, making it easier to transport other transport jigs on the transport rail 53. In FIG. 15, the transport rod 38 transports the screen mask 55 by pushing the end (rear end in this case) from the outside, but the invention is not limited to this; for example, the transport rod 38 can transport the screen mask 55 by pushing the inside of the frame 57. The screen mask 55 may also be transported. Similarly, when transporting a transport jig such as the squeegee transport jig 110 described later, the transport rod 38 may push the end of the transport jig from the outside, or the inside of the transport jig (for example, inside the frame 111). Alternatively, the replaceable member 13 attached to the transport jig may be pushed.

The squeegee replacement process in step S130 will be explained. When the squeegee replacement process is started, the print control unit 11 performs a squeegee unloading process for unloading the squeegee 30 and a squeegee loading process for loading a replacement squeegee 30. FIG. 16 is an explanatory diagram showing the state of the squeegee carry-out process. In the squeegee carry-out process, the print control unit 11 first makes sure that the conveyor 104 (here, the second conveyor 104b) on which the squeegee conveyor jig 110 with the empty holder 112 is placed is at the same height as the conveyor rail 53. The conveyor elevating section 105 is operated so that the height (unloading height) is reached. That is, the printing control unit 11 positions the second conveyor 104b at the same height as the above-mentioned unloading height of the screen mask 55. Then, the second transport conveyor 104b and the transport rod 38 are controlled to transport the squeegee transport jig 110 into the printing apparatus 10 (FIG. 16A). Next, the printing control section 11 controls the printing movement section 22 and the squeegee lifting section 23 to move the first squeegee 30a attached to the squeegee fixing section 24 forward, and fills the empty space on the front side of the squeegee conveyance jig 110. Attach the first squeegee 30a to the holder 112 (FIG. 16B). Similarly, the print control unit 11 moves the second squeegee 30b backward and attaches the second squeegee 30b to the empty holder 112 on the back side of the squeegee conveyance jig 110 (FIG. 16C). Then, the print control unit 11 transports the squeegee transport jig 110 to which the squeegee 30 is attached to the second transport conveyor 104b by the transport rod 38, and carries out the squeegee transport jig 110 (FIG. 16D). Furthermore, the print control unit 11 causes the second conveyor 104b to further convey the squeegee conveyance jig 110 forward, and stores the squeegee conveyance jig 110 in the storage section 102.

In the squeegee carry-in process, the print control unit 11 carries the squeegee 30 in the reverse procedure of the squeegee carry-out process described above. That is, the printing control unit 11 first sets the third conveyor 104c on which the squeegee conveying jig 110 with the replacement squeegee 30 attached thereto so that the conveyance rail 53 is at the same height (carry-in height). The conveyor lifting section 105 is operated. Next, the printing control unit 11 transports the squeegee transport jig 110 using the third transport conveyor 104c and the transport rod 38. Next, the print control unit 11 controls the print moving unit 22 and the squeegee lifting unit 23 to move the front squeegee fixing unit 24 forward, and the squeegee 30 attached to the front holder 112 of the squeegee conveyance jig 110 moves forward. Attach it to the front squeegee fixing part 24. Similarly, the print control unit 11 moves the rear squeegee fixing unit 24 rearward, and attaches the squeegee 30 attached to the rear holder 112 of the squeegee conveyance jig 110 to the rear squeegee fixing unit 24. Thereafter, the print control unit 11 carries out the squeegee conveying jig 110 from which the squeegee 30 has been removed using the conveying rod 38, and causes the third conveyor 104c to store the squeegee conveying jig 110 in the storage section 102.

Here, the delivery of the squeegee 30 from the squeegee fixing part 24 to the holder 112 and the receiving of the replacement squeegee 30 from the holder 112 to the squeegee fixing part 24 will be described in detail. For convenience of explanation, receiving the squeegee 30 will be explained first. FIG. 17 is an explanatory diagram of the operation of attaching the squeegee 30 to the squeegee fixing part 24. Note that FIG. 17 shows how the front squeegee fixing part 24 receives the squeegee 30. 17 is a schematic cross-sectional view of the positioning member 33 and the air cylinder 25 along the vertical and front-back directions, and the center 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-back directions. 17, the right column of FIG. 17 is a perspective view of the squeegee fixing part 24 and the squeegee 30 seen from the upper right front. When receiving the squeegee 30, the print control unit 11 first lowers the squeegee fixing part 24, puts the squeegee fixing part 24 in a released state, and moves the squeegee fixing part 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 regulating member 26. Then, at a position where the cylinder shaft 25a comes into contact with the positioning member 33 and forward movement of the cylinder shaft 25a is restricted by the positioning member 33, the two 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) comes into contact with the front surface of the cylinder shaft 25a. 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. Furthermore, when the squeegee fixing part 24 is located at the receiving position, the recess 28a of the regulating member 26 is located directly above the protrusion 34 of the squeegee 30 (FIG. 17B). Subsequently, the print control section 11 controls the air cylinder 25 to switch the squeegee fixing section 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 grasped 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 is moved to the removal position. Further, the protruding portion 34 of the squeegee 30 rises, fits into the recesses 28a and 28b of the squeegee fixing portion 24, and engages with the regulating member 26. The engagement between the restricting member 26 and the protruding portion 34 restricts the movement of the squeegee 30 in the front-rear direction relative to the squeegee fixing portion 24 . In addition, 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 connected to the upper surface of the cylinder shaft 25a of the squeegee fixing part 24 and the lower surface of the regulating member 26. By being held, the squeegee 30 is gripped and fixed to the squeegee fixing part 24. Then, the print control section 11 controls the print movement section 22 to move the squeegee fixing section 24 backward. 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). Note that when receiving the second squeegee 30b for replacement from the holder 112 on the rear side of the squeegee conveyance jig 110 to the squeegee fixing section 24, the printing control section 11 may perform an operation that is symmetrical to the above-mentioned operation.

The squeegee 30 can be transferred from the squeegee fixing part 24 to the holder 112 by the reverse procedure of the above-mentioned receiving procedure. When transferring the first squeegee 30a to the holder 112 on the front side of the squeegee transport jig 110, the print control unit 11 first lowers the squeegee fixing part 24 on the front side, and then inserts the squeegee fixing part 24 from the rear of the holder 112. Move it forward. This positions the flange portion 36 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, the squeegee 30 is located at the attachment position, and the squeegee 30 is attached to the holder 112. Further, the engagement between the regulating member 26 and the protrusion 34 is released. Then, the print control section 11 moves the squeegee fixing section 24 backward. Note that when delivering the second squeegee 30b to the holder 112 on the rear side of the squeegee conveying jig 110, the print control unit 11 may perform an operation that is symmetrical to the above-mentioned operation.

The substrate support member replacement process in step S140 will be explained. When the substrate support member replacement process is started, the print control unit 11 performs a substrate support member carry-in process to carry out the substrate support member 70 and a substrate support member carry-in process to carry in the replacement substrate support member 70. FIGS. 18 and 19 are explanatory diagrams of the substrate support member carrying-out process. In the substrate support member carrying-out process, the printing control unit 11 first moves the support member transporting jig in which at least one of the first and second protrusion holding parts 132 and 133 and the third and fourth protrusion holding parts 134 and 135 is vacant. The conveyor elevating section 105 is operated so that the conveyor 104 (here, the eighth conveyor 104h) on which the ingredients 130 are placed and the conveyor rail 53 are at the same height (unloading height). That is, the print control unit 11 positions the eighth conveyor 104h at the same height as the above-mentioned unloading height of the screen mask 55. Next, the printing control unit 11 controls the eighth conveyor 104h and the conveying rod 38 to carry the support member conveying jig 130 into the printing apparatus 10 (FIG. 18A). Note that the print control unit 11 is configured such that the protrusion holders (here, the third and fourth protrusion holders 134 and 135) to which the substrate support member 70 is attached are moved from directly above the protrusions 71 and 72 of the substrate support member 70 in the front-rear direction (here The supporting member conveying jig 130 is conveyed so that it is shifted to the rear). Subsequently, the printing control unit 11 causes the pair of side frames 60b, 60b to be separated back and forth by the substrate guide moving unit 63, and controls the support platform lifting unit 65 and the fixed part lifting unit 66 to raise the substrate support member 70. (Figure 18B). As a result, the protrusions 71 and 72 of the substrate support member 70 rise above the first to fourth protrusion holding parts 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 transport jig 130 forward using the transport rod 38 to place the third and fourth protrusion holding parts 134 and 135 directly below the protrusions 71 and 72 of the substrate support member 70. (Figure 18C). Then, the print control unit 11 lowers the support stand 67. As a result, the protrusions 71 and 72 of the substrate support member 70 engage with the third and fourth protrusion holding parts 134 and 135, and the substrate support member 70 becomes attached to the support member conveyance jig 130 (FIG. 19A). Thereafter, the print control unit 11 lowers the entire substrate fixing unit 60 and transports the support member transport jig 130 to which the substrate support member 70 is attached forward by the transport rod 38 . Take it out (Figure 19B). Further, the print control unit 11 causes the eighth conveyor 104h to further convey the supporting member conveying jig 130 forward, and stores the supporting member conveying jig 130 in the storage section 102. Note that the printing control section 11 may perform the next substrate support member loading process without lowering the substrate fixing section 60.

The printing control unit 11 can carry out the substrate support member import process in the reverse procedure to the above-described substrate support member carry-out process. In the substrate support member loading process, the print control unit 11 first makes sure that the ninth conveyor 104i on which the support member conveyor jig 130 to which the replacement substrate support member 70 is attached is placed at the same height as the conveyor rail 53. The conveyor elevating section 105 is operated so as to reach the (carry-in height). Next, the print control unit 11 transports the support member transport jig 130 using the ninth transport conveyor 104i and the transport rod 38, and transports the replacement substrate support member 70 to above the support table 67. Subsequently, the printing control unit 11 raises the support base 67 to raise the substrate support member 70 and connect the protrusions 71 and 72 to the protrusion holders (here, the third and fourth protrusion holders 134 and 135). Release the engagement. The position of the substrate support member 70 at this time is the receiving position of the substrate support member 70. After that, the printing control unit 11 moves the supporting member conveying jig 130 forward or backward to shift the positions of the protrusions 71 and 72 and the third and fourth protrusion holding parts 134 and 135 back and forth, and then supports The platform 67 is lowered. Then, the print control unit 11 lowers the entire substrate fixing unit 60 and transports the support member transport jig 130 forward by the transport rod 38 to carry out the support member transport jig 130. Further, the print control unit 11 causes the ninth conveyor 104i to further convey the supporting member conveying jig 130 forward, and stores the supporting member conveying jig 130 in the storage section 102.

The mask loading process in step S150 will be explained. The print control unit 11 can carry out the mask carry-in process in the reverse order of the mask carry-out process described above. In the mask carry-in process, the print control unit 11 first positions the conveyor 104 (here, the seventh conveyor 104g) at the height (carry-in height) for carrying in the replacement screen mask 55. The conveyor elevating section 105 is operated. The carrying-in height of the screen mask 55 is the same as the carrying-out height of the screen mask 55. Next, the printing control unit 11 transports the replacement screen mask 55 backward by the seventh transport conveyor 104g and the transport rod 38, and carries in the replacement screen mask 55. After performing steps S100 to S150 above, the print control unit 11 ends the exchange processing routine.

The printing apparatus 10 of the present embodiment described in detail above includes the cartridge 49, the squeegee 30, the cleaning member 82, the screen mask 55, and the substrate support member 70. 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 the movement of the replaceable member 13 to the replacement position and the carrying in and out of the replaceable member 13 are performed. It is equipped with a moving part that performs one of the two. More specifically, the moving section includes a print moving section 22 and a supply moving section 46 that move the cartridge 49 to the exchange position and carry the cartridge 49 in and out, and a print moving section 22 and a supply moving section 46 that move the squeegee 30 to the exchange position. It includes a squeegee elevating section 23, a printing moving section 22 for carrying in and out the squeegee 30, a conveyance rod 38, and a conveyance rail 53. Further, the moving section includes a cleaning moving section 87 that moves the cleaning member 82 to the replacement position and carries in and out the cleaning member 82, a printing moving section 22 that carries in and out the screen mask 55, a conveyance rod 38, and a conveyance rail 53. , a support platform elevating section 65 and a fixed section elevating section 66 that move the substrate support member 70 to the replacement position, a print moving section 22, a transport rod 38, and a transport rail 53 that transport the board support member 70 in and out. , is equipped with. The printing apparatus 10 includes a printing control section 11 that controls the moving section and executes a replacement process for replacing the replaceable member 13. Therefore, the printing apparatus 10 can automatically replace two or more types (five types in this embodiment) of replaceable members 13.

Further, in the printing apparatus 10, the moving unit has a common moving mechanism that moves two or more types of members included in the replaceable member 13. Specifically, the print moving unit 22 is a common moving mechanism for moving the cartridge 49, the squeegee 30, the screen mask 55, and the substrate support member 70. The transport rod 38 and the transport rail 53 are common moving mechanisms for moving the squeegee 30, the screen mask 55, and the substrate support member 70. Therefore, the printing apparatus 10 can automatically replace two or more types of replaceable members 13 using the same moving mechanism. Therefore, the printing device 10 can have a more compact device configuration than, for example, a case where the printing device 10 includes separate moving mechanisms for each type of replaceable member 13.

Furthermore, the printing device 10 commonly uses two or more types of members included in the replaceable member 13, and at least one of the member and the transport jig for the member (in this embodiment, the screen mask 55 and each transport jig 110). , 120, 130, and 140). Thereby, the printing device 10 can identify the replaceable member 13 by reading each barcode, and therefore can perform the replacement process more appropriately. Further, since the printing device 10 uses the same reading unit 97 to read barcodes for each of two or more types of members (all five types in this embodiment), for example, the printing device 10 reads different barcodes for each type of replaceable member 13. The device configuration can be made more compact compared to the case where a reading section is provided.

Furthermore, the printing device 10 is capable of transporting the replaceable members 13 into and out of the storage device 100 that stores the replaceable members 13, and the printing control unit 11 controls the exchangeable members stored in the storage device 100. One or more types of identification information among the 13 are read by the reading unit 97 during printing processing. Therefore, the printing device 10 can read one or more of the barcodes 57a, 116, 126, 136, and 146 on the replaceable member 13 in advance before the replacement process. Therefore, the printing device 10 can perform the exchange process in a shorter time than when reading all barcodes during the exchange process.

Furthermore, in order to cause the reading unit 97 to read one or more barcodes among the replaceable members 13, the print control unit 11 positions the replaceable members 13 stored in the storage device 100 so that the reading unit 97 can read them. A command is output to the storage device 100 to move the storage device 100 up to the point where the storage device 100 moves. Therefore, even if the reading unit 97 cannot read each barcode 57a, 116, 126, 136, and 146 while stored in the storage device 100, the print control unit 11 moves the replaceable member 13 to the storage device 100. This allows the reading section 97 to read each barcode 57a, 116, 126, 136, and 146. Furthermore, since the barcode is read during the printing process, even if the storage device 100 moves the replaceable member 13 for reading, there is little effect on the time required for the replacement process.

The storage device 100 also includes a storage section 102 that stores the above-mentioned replaceable members 13, and one or more types of the replaceable members 13 (in this embodiment, a squeegee 30, A conveyor 104 for carrying in and out three types of screen masks 55 and substrate supporting members 70 is provided. Therefore, since the printing device 10 only needs to transfer the replaceable member 13 with the storage device 100 instead of with the operator, it becomes easier for the printing device 10 to automatically replace the replaceable member 13. Furthermore, the printing control unit 11 carries out the loading and unloading of cartridges 49 and exchange modules 81 that are not carried in and out by conveyance on the conveyor 104 using a mechanism on the printing apparatus 10 side.

The storage device 100 also includes a conveyor lifting section 105 that moves up and down the storage section 102, and the storage section 102 has a storage area 103 that stores at least one type (all five types in this embodiment) of the replaceable members 13. It has nine stages in the vertical direction. Therefore, since each of the plurality of storage areas 103a to 103i can store a replaceable member 13, the storage portion 102 can easily store two or more types of replaceable members 13. Furthermore, since the conveyor elevating section 105 can adjust the height of the replaceable member 13 when transferring the replaceable member 13 to and from the printing device 10, this storage device 100 can be used for each printing device 10 or for each replaceable member 13. The exchangeable member 13 can be delivered at an appropriate height for each type.

The storage unit 102 also stores the replaceable member 13 (cartridge 49 here) that has the highest height at which it is carried into the printing apparatus 10 among the replaceable members 13 into the first storage area at the top of the multiple storage areas 103. It is stored in area 103a. Therefore, compared to the case where, for example, the cartridge 49 having the highest loading height is stored in a location other than the first storage area 103a at the top, it is easier to reduce the lifting range required for the conveyor lifting section 105.

Furthermore, the storage section 102 stores the replacement module 81 including the cleaning member 82 attached to the protrusion holding section 142 of the cleaning member conveyance jig 140, and the conveyor elevating section 105 moves the cleaning member 81 by raising and lowering the storage section 102. By raising and lowering the transport jig 140, the replacement module 81 to be received (delivered) from the printing apparatus 10 is attached to the cleaning member transport jig 140. In addition, the conveyor elevating unit 105 lifts and lowers the cleaning member conveying jig 140 by raising and lowering the storage unit 102, thereby removing the exchange module 81 attached to the cleaning member conveying jig 140 from the cleaning member conveying jig 140 and printing. Transfer to device 10. Therefore, the conveyor elevating section 105 can also serve as a mechanism for transferring the exchange module 81 between the storage device 100 and the printing device 10.

It goes without saying that the present invention is not limited to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention.

For example, in the above-described embodiment, the storage unit 102 stores the cartridge 49, which has the highest loading height into the printing device 10 among the replaceable members 13, in the first storage area 103a at the top. Not limited. Further, the storage unit 102 may store the member having the lowest height when being carried into the printing apparatus 10 among the replaceable members 13 in the lowest stage of the plurality of storage areas. For example, the cleaning member 82 may be stored in the ninth storage area 103i on the ninth conveyor 104i.

In the embodiment described above, the print control unit 11 performs the reading process during the print 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 exchange process in FIG. 11. Alternatively, instead of performing the reading process, the print control unit 11 may input information regarding the replaceable member 13 and the transport jig stored in the storage unit 102 from the management PC 150 or receive information from the operator via the display operation unit 98. You can also enter the Further, a rule may be predetermined as to which empty transport jig should be stored in which storage area 103, or which type of replaceable member 13 should be stored in which storage area 103. Such rules may be determined in advance. In this case, the print control unit 11 stores the rules in advance, and if the operator stores the transport jig and the replaceable member 13 in the storage area 103 according to the rules, the print control unit 11 will not perform the reading process. It's okay.

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

In the embodiment described above, the exchangeable member 13 transported by the transportation jig has a barcode attached to the transportation jig, but the barcode is not limited to this, and the exchangeable member 13 may also have a barcode attached. . Further, in the above-described embodiment, a bar code is attached to the conveying 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 embodiment described above, the printing device 10 has the printing movement unit 22 as a movement mechanism common to four types of movement among the five types of replaceable members 13, but the present invention is not limited to this, and all five types of movement are possible. may have a common movement mechanism. For example, although the mounting member moving mechanism 89 switches the replacement module 81 and the mounting member 84 between the protruding state and the non-protruding state, this switching may be performed by the transport rod 38. For example, the transport rod 38 may be configured to protrude downward to the same height as the exchange module 81, and the print moving unit 22 may move the transport rod 38 back and forth to switch between the protruding state and the non-protruding state. In this case, the print moving unit 22 serves as a common moving mechanism for moving all five types of replaceable members 13. The printing apparatus 10 also includes a common movement mechanism for moving two or more members including the squeegee 30, the screen mask 55, and the substrate support member 70 (for example, the printing moving unit 22, the transport rod 38, and the transport rail 53). ). Alternatively, the printing apparatus 10 may use a common movement mechanism (for example, It may also include a printing moving section 22 and a conveying rod 38).

In the embodiment described above, the print control unit 11 performs the mask unloading process before performing the squeegee replacement process in the exchange process routine, but the present invention is not limited to this. For example, if the squeegee conveying jig 110 and the squeegee fixing section 24 can transfer the squeegee 30 in an area in front of the screen mask 55 without retracting the screen mask 55, the print control section 11 There is no need to carry out the mask unloading process before the exchange process.

Although not particularly described in the above-described embodiment, the print control unit 11 stores 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. When the print control unit 11 determines that the necessary replacement replaceable member 13 is not stored, it outputs error information indicating this to at least one of the display operation unit 98 and the management PC 150, and The operator may be informed that the replaceable member 13 is in short supply. Note that when the printing control unit 11 determines that a necessary replaceable member 13 is not stored, it may perform a process of replacing a type of replaceable member 13 other than the replaceable member 13. For example, even if the replacement cartridge 49 is not stored in the storage device 100, if any of the other four types of replaceable members 13 needs to be replaced, the print control unit 11 can replace them. Processing may be executed. In this way, while the operator is preparing the missing replaceable member 13, the other replaceable member 13 can be replaced.

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

In the embodiment described above, the storage device 100 is provided with a moving section and is movable by the operator, but the storage device 100 is not limited to this and does not need to include the moving section. Further, the storage device 100 may be configured as a self-propelled AGV (Automatic Guided Vehicle) having a drive mechanism that drives a moving section. In this case, the storage device 100 may move to a location where the replacement replaceable member 13 is stored, and automatically store the replacement replaceable member 13 in the storage section 102.

In the above-described embodiment, the replacement of the replaceable member 13 was mainly explained when changing the setup, but the replacement timing is not limited to this. For example, for consumables such as the cartridge 49 and the cleaning member 82, the print control unit 11 may perform a replacement process when a sensor that detects the remaining amount detects that the consumables are out of stock.

In the embodiment described above, the printing device 10 automatically exchanges all five types of replaceable members 13 with the storage device 100, but the present invention is not limited to this. 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 members 13 can be attached. In this case, if the operator attaches the replaceable member 13 to at least one holder and leaves at least one holder empty, the printing device 10 can automatically exchange the holder with the holder. can. In this manner, the printing apparatus 10 may perform a replacement process for one or more of the replaceable members 13 without carrying them in or out.

In the embodiment described above, the storage device 100 stores all of the replaceable members 13 other than the screen mask 55 in the storage unit 102 while being attached to the transport jig, but the replaceable members 13 other than the screen mask 55 are stored in the storage unit 102 while being attached to the holder. All you have to do is stay there. For example, the storage device 100 may store one or more types of replaceable members 13 other than the screen mask 55 while being attached to a holder that cannot be transported by the transport conveyor 104. Even in this case, if the printing device 10 has a mechanism for transferring the replaceable member 13 to and from the storage device 100, automatic replacement can be performed as in the embodiment described above. For example, in the storage device 100 of the above-described embodiment, the cartridge 49 and the replacement module 81 can be automatically replaced without the storage device 100 transporting them back and forth, so at least one of the cartridge 49 and the replacement module 81 is It may be attached to a fixed holder instead of the transport jig.

In the embodiment described above, the printing device 10 is configured to be able to automatically replace all five types of replaceable members 13; however, the present invention is not limited to this, and one type including at least one type other than the screen mask 55 can be replaced automatically. The above-described replaceable member 13 may be automatically replaced. Furthermore, if the printing device 10 is capable of automatically replacing two to four of the five types of replaceable members 13, any combination of the five types of automatically replaceable replaceable members 13 may be selected. . Moreover, one to four types of members among the five types of replaceable members 13 may be configured so that they cannot be replaced by an operator (that is, they are not replaceable members). Furthermore, the printing device 10 does not need to include one or more of the five types of replaceable members 13. For example, the printing apparatus 10 may not include the cleaning section 80 including the cleaning member 82.

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

In the printing device of the present disclosure, the moving unit may have a common moving mechanism that moves two or more types of members included in the replaceable member. In this way, this printing apparatus can automatically replace each of two or more types of replaceable members using the same moving mechanism. Therefore, this printing apparatus can have a more compact apparatus configuration than, for example, a case where the printing apparatus includes separate moving mechanisms for each type of replaceable member.

The printing device of the present disclosure includes a reading unit that reads identification information attached to at least one of the member and the conveying jig for the member, common to two or more types of members included in the replaceable member. Good too. In this way, the printing apparatus can identify the replaceable member by reading the identification information, so that the replacement process can be performed more appropriately. In addition, since this printing device uses the same reading section to read the identification information for each of two or more types of members, the device structure is can be made compact.

In this case, the printing device is capable of transporting the replaceable member into and out of a storage device that stores the replaceable member, and the exchange control unit is configured to control the exchangeable member stored in the storage device. The reading unit may read identification information of one or more of the members during the printing process. In this way, this printing device can read in advance the identification information of one or more types of replaceable members 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 replaceable members during the replacement process.

In this case, in order to cause the reader to read one or more types of identification information among the replaceable members during the printing process, the exchange control unit may read the replaceable member stored in the storage device by the reader. A command may be output to the storage device to move the part to a readable position. In this way, even if the reading section cannot read the identification information while the replaceable member is stored in the storage device, the replacement control section moves the replaceable member to the storage device so that the reading section 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, there is little effect on the time required for the replacement process.

The storage device of the present disclosure includes:
A member used in a printing device that performs a printing process using a viscous fluid on a printing target using a screen mask, the member comprising: a cartridge containing the viscous fluid; a squeegee; and a cleaning member used to clean the screen mask. , a storage unit that stores two or more types of replaceable members, including at least one of the cartridge, the squeegee, and the cleaning member, among the screen mask and a support member that fixes the printing target;

It is equipped with the following.

This storage device stores two or more types of replaceable members, and transports one or more of the replaceable members into and out of the printing device. Therefore, since the printing device only needs to transfer the replaceable member to the storage device rather than to the operator, it becomes easier for the printing device to automatically replace the replaceable member. This storage device may exchange replaceable members with the printing device of the present disclosure in any of the above embodiments. Note that if there is a replaceable member that is not transported by the transport unit of the storage device, the replaceable member may be transported by a mechanism on the printing device side.

The storage device of the present disclosure may include an elevating section that moves up and down the storage section, and the storage section may have a plurality of storage areas in the vertical direction for storing at least one type of the replaceable member. In this way, each of the plurality of storage areas can store a replaceable member, so that the storage section can easily store two or more types of replaceable members. In addition, since the lifting section can adjust the height of the replaceable member when transferring the replaceable member to and from the printing device, this storage device can adjust the height appropriately for each printing device and each type of replaceable member. Exchangeable parts can be delivered and exchanged.

In this case, the storage unit may store the member that has the highest loading height to the printing apparatus among the replaceable members in the uppermost stage of the plurality of storage areas, or The member having the lowest height to be carried into the printing apparatus may be stored in the lowest stage of the plurality of storage areas, or at least one of the following may be performed. In this way, for example, when storing a component with the highest loading height in the top shelf of multiple storage areas, the required lifting range of the lifting section can be reduced compared to when storing it in a location other than the top shelf. Easy to make small. Similarly, for example, when storing a component with the lowest loading height in the lowest level of multiple storage areas, the lifting range required for the lifting section is smaller than when storing it in a location other than the lowest level. Easy to make small.

The storage device of the present disclosure includes an elevating section that moves up and down the storage section, the storage section stores one or more of the replaceable members in a state attached to a holder, and the elevating section , by raising and lowering the holder by raising and lowering the storage section, the replaceable member received from the printing device is attached to the holder, or the replaceable member attached to the holder is removed from the holder and attached to the printing device. or at least one of the following. In this way, the elevating section that raises and lowers the storage section can also serve as a mechanism for transferring the replaceable member between the storage device and the printing device. Note that the holder may be fixed to the storage section or may be transportable. For example, the replaceable member may be attached to a holder included in a transport jig that can be transported by the transport unit.
