Fig. 10 is a block diagram showing an electrical connection relationship of the printing system 12. The mounting system 10 is, for example, a system for mounting components on a substrate S to be processed. The mounting system 10 includes a printing device 11, a mounting device 13, an automated guided vehicle 18, and a management computer (PC) 60. The mounting system 10 is configured to have a mounting line in which a plurality of mounting devices 13 for mounting components on a substrate S are disposed downstream of the printing device 11. The printing system 12 is composed of the printing apparatus 11, the replacement unit 40, the housing rack 90, and the management PC80 mainly managing functions of the printing apparatus 11. In the present embodiment, the left-right direction (X axis), the front-rear direction (Y axis), and the up-down direction (Z axis) are shown in fig. 1 to 9.

The warehouse area 15 is an area in which replaceable components (hereinafter also simply referred to as components) or the like used in the mounting system 10 are prepared. As the components used in the mounting system 10, for example, a screen mask M, a support member 32 to which a processing object is fixed, a squeegee 25 to which solder paste as a viscous fluid is applied in a printing process, a cartridge 36 to house the viscous fluid, a cleaning member 34 to clean the screen mask M, and the like are exemplified in the printing apparatus 11. An arm robot 16 and a preparation table 17 are disposed in the warehouse area 15. The arm robot 16 performs a work of placing the storage rack 90 prepared for the subsequent use from the preparation table 17 to the automated guided vehicle 18 and a work of moving the used storage rack 90 collected by the automated guided vehicle 18 to the preparation table 17. The preparation table 17 is a work table on which a new housing bracket 90 is placed and the used housing bracket 90 is housed. The arm robot 16 is controlled by a control PC, not shown. The control PC receives a replacement instruction from the management PC80 via a network line, and outputs information such as the work status of the arm robot 16 to the management PC 80. In the warehouse area 15, the storage rack 90 may be moved and prepared by an operator.

The mounting device 13 is a device for mounting components on a substrate S printed with a viscous fluid such as solder paste by the printing device 11.

The automated guided vehicle 18 moves between the warehouse area 15, which stores components related to the mounting process and is prepared for use, and the mounting line, for example, automatically conveys the housing rack 90 housing components such as the screen mask M. The replacing unit 40 that receives the storage rack 90 is connected to the printing apparatus 11, and the automated guided vehicle 18 transfers the storage rack 90 to the replacing unit 40. The automated guided vehicle 18 may be an AGV that moves along a line formed on the ground or the like, or may be an AMR that autonomously travels based on signals obtained from a sensor, a camera, or the like. The automated guided vehicle 18 includes a controller, a driving unit, a communication unit, and a mounting unit. The controller controls the whole device. The driving unit is a motor that drives and rotates the wheels, and is controlled by a controller. The communication unit is a wireless interface for communicating with external devices such as the printing apparatus 11 and the management PC 80. The automated guided vehicle 18 transmits and receives commands and signals to and from the management PC80 and the printing apparatus 11 via the communication unit. The automated guided vehicle 18 has a mounting portion on its upper surface for mounting components such as the housing bracket 90. The automated guided vehicle 18 enters a lifting space 50 formed in the center of the replacement unit 40, and receives and transfers the storage rack 90 to and from the replacement unit 40.

As shown in fig. 1, 2, and 10, the printing device 11 is a device that presses solder on the screen mask M into pattern holes formed in the screen mask M by a squeegee 25, and applies (prints) solder as a viscous fluid to a substrate S to be processed therebelow through the pattern holes. Here, examples of the "processing target" include a substrate S on which the element is mounted, a substrate as a three-dimensional object, and the like. Examples of the "viscous fluid" include solder paste, conductive paste, and adhesive. Here, the substrate S and solder will be described below as examples. The screen mask M is fixed to the inside of the frame 29. The frame 29 can fix screen masks M of various sizes, and has a size that can be accommodated in the shelf 91 of the accommodating bracket 90 (see fig. 1). As shown in fig. 10, the printing apparatus 11 includes a print control unit 21, a printing unit 22, a mask working unit 26, a substrate processing unit 30, a cleaning unit 33, and a supply unit 35.

The print control unit 21 is configured as a microprocessor centering on a CPU, and controls the entire printing apparatus 11.

For example, the print control unit 21 outputs request information for requesting movement of the housing rack 90 to the management PC80 as the management device according to the use condition of the replaceable component in the printing unit 22. The print control unit 21 receives a reception signal from the automated guided vehicle 18 indicating that the storage rack 90 is mounted on the replacement unit 40. The print control unit 21 controls the replacement unit 27 to replace the screen mask M between the housing bracket 90 and the printing unit 22. The print control unit 21 includes a storage unit that stores information of the substrate S to be printed, a print processing program for performing print processing on the substrate S, a component replacement processing program for performing replacement processing of the housing 29 by the replacement unit 27, and the like.

The printing unit 22 is disposed at an upper stage of the printing apparatus 11, and performs a printing process on the substrate S with a viscous fluid using the screen mask M. As shown in fig. 1 and 4, the printing section 22 includes a print head 23, a printing moving section 24, a squeegee lifting section, a squeegee 25, and a passage 19. The print moving unit 24 moves the print head 23 in a predetermined print direction (here, the front-rear direction), and includes a guide formed in the front-rear direction, a slider moving along the guide, and a motor driving the slider. The squeegee 25 is disposed on the lower surface side of the print head 23, and is lifted by a squeegee lifting section. The printing section 22 has two squeegees 25 respectively used in the front-rear direction. A wall portion on the front surface of the housing of the printing apparatus 11 is provided with a passage opening 19 through which the housing 29 can pass. As shown in fig. 3, a tapered portion 19a is formed along the guide 26a of the mask working portion 26 so as to guide the frame 29 to a fixed position behind the fixed frame 29 at the passage opening 19. The tapered portion 19a has a tapered surface in which the passage of the housing 29 is narrowed toward the fixed position, and is disposed on both sides of the passage opening 19. As shown in fig. 2, the mask working unit 26 is disposed between the printing unit 22 and the substrate processing unit 30 in the vertical direction, and is a unit for fixedly holding the screen mask M. As shown in fig. 10, the mask working unit 26 includes a replacement unit 27 and a mask fixing unit 28. The replacement portion 27 is a transport lever provided to the print head 23, and is lowered to a position where it contacts the screen mask M by an unillustrated cylinder, and is rotated to move the contact portion that contacts the frame 29 in the front-rear direction (see the broken line in fig. 2). The print head 23 and the replacement part 27 are engaged with the frame 29 between the shelf part 91 and the printing part 22, which are at a predetermined height of the housing bracket 90, to move the frame 29. The mask fixing portion 28 positions the screen mask M and supports and fixes it in a horizontal posture. The screen mask M is pushed by the replacement part 27, moves back and forth along the guide of the mask working part 26, and is fixed by the mask fixing part 28. As shown in fig. 2, the substrate processing unit 30 is disposed below the mask working unit 26, and is a unit for loading the substrate S, positioning and supporting the loaded substrate S so as to be in contact with and separated from the screen mask M. The substrate processing unit 30 includes: a substrate conveying section 31 for conveying the substrate S in the left-right direction; a support member 32 that supports the substrate S from below; and a substrate lifting section for lifting and lowering the entire substrate processing section 30 and the support member 32. The cleaning unit 33 is disposed between the mask working unit 26 and the substrate processing unit 30 in the vertical direction, and is a unit for performing cleaning processing for cleaning the back surface of the screen mask M. The cleaning unit 33 includes a cleaning member 34, and the screen mask M is cleaned by the cleaning member 34. The supply unit 35 is a unit that supplies solder stored in the cartridge 36 onto the screen mask M. The supply unit 35 is disposed in front of the print head 23. The supply unit 35 applies pressure to the cartridge 36 to eject solder from the cartridge 36. The cleaning member 34 and the cartridge 36 are consumable parts, and are replaced as needed.

The replacement unit 40 is configured to receive the housing bracket 90 housing the replaceable components such as the screen mask M fixed to the housing 29, and to raise and lower the housing bracket 90. The replacement unit 40 has a pair of left and right units 41 and 61 as lifting units of the present disclosure, and a replacement control unit 70. The replacement unit 40 has a lifting space 50 in which the housing bracket 90 is lifted and lowered in the center of the left unit 41 and the right unit 61.

The left unit 41 is disposed on the front left side of the housing of the printing apparatus 11. The left unit 41 includes a receiving portion 42, a driving portion 43, and a replacement portion 44. The receiving portion 42 receives a receiving bracket 90 that receives the frame 29 that supports the screen mask M, and supports the receiving bracket 90 from the lower surface side. The receiving portion 42 may fix the housing bracket 90 by magnetic force, for example. The driving unit 43 lifts and lowers the receiving unit 42 to lift and lower the housing bracket 90. The driving unit 43 may include, for example, a ball screw having a lifting shaft and a driving motor, or may be a linear motor. The replacement unit 44 is driven by abutting against the housing 29, and replaces the housing 29 between the housing bracket 90 and the printing unit 22. The replacement unit 44 includes a delivery unit 45 and a moving unit 46. The feeding section 45 includes a belt 47 for moving the frame 29 toward the printing apparatus 11 or the housing holder 90 by friction force of the surface 47a, and a driving section 48 for rotating the belt 47. The driving unit 48 is configured as a servo motor, for example. As shown in fig. 4, the feeding unit 45 is configured to transmit power of the driving unit 48 to the belt 47 via a plurality of pulleys 49. The moving unit 46 is configured to move the feeding unit 45 in a direction (in this case, a left-right direction) approaching or separating from the housing 29 accommodated in the accommodating rack 90, and is configured as, for example, a cylinder or a linear motor.

The right unit 61 has a receiving portion 62. The right unit 61 is disposed on the front right side of the casing of the printing apparatus 11. The right unit 61 includes a receiving portion 62 and a driving portion 63. The receiving unit 62 and the driving unit 63 are the same as the receiving unit 42 and the driving unit 43, and therefore, the description thereof will be omitted.

The replacement control unit 70 is configured as a microprocessor centering on a CPU, and controls the entire replacement unit 40. The replacement control unit 70 outputs signals to the driving units 43 and 63 and the print control unit 21. The replacement control unit 70 receives a signal from the print control unit 21. The replacement control unit 70 performs a process of moving the housing bracket 90 from the ascent position to the replacement position by the driving unit 43. When the replacement of the replaceable component is completed, the replacement control unit 70 lowers the storage bracket 90 from the replacement position to the liftable position (the receiving portions 42 and 62 are lowered to the lowest positions) by the driving unit 43.

The housing bracket 90 is a housing body that houses the frame body 29, and the frame body 29 can support the screen mask M as a replaceable component related to the printing process performed by the printing portion 22. As shown in fig. 2 and 5 to 8, the housing bracket 90 includes a bracket main body 90a, an opening 92, a plurality of shelf portions 91, and a cover member 93. As shown in fig. 5 and 6, an insertion space 95 is provided in the holder main body 90a, and the insertion space 95 is used for inserting the delivery unit 45 of the replacement unit 44 when the replaceable component is replaced between the storage holder 90 and the printing apparatus 11. The insertion space 95 is a groove-like space formed at a position of each shelf portion 91 on a side surface facing the left unit 41. The insertion space 95 is formed on a side surface of one side of the holder main body 90 a. The opening 92 communicates with the outside such as the passage opening 19 of the printing unit 22, and the frame 29 is carried in and out through the opening 92. The shelf 91 accommodates the housing 29 at a predetermined accommodation position. The holder main body 90a includes shelf portions 91 for inserting and supporting the end portions of the frame 29 at the left and right sides. The shelf portions 91 are arranged at predetermined intervals in the vertical direction so that the frame 29 supporting the screen mask M can be placed thereon in the vertical direction. The shelf portion 91 is a member having a substantially L-shaped cross-sectional shape. The left shelf 91 is provided with a follower 94 that moves in response to the movement of the frame 29 and supports the frame 29 on a support surface that supports the frame 29. The driven portion 94 is attached to the support surface and the side surface of the right shelf portion 91. The driven portion 94 is configured as, for example, a ball wheel. The driven portion 94 may be a conveying roller. Between the left and right shelf portions 91, the frame 29 is formed as a passage 91a that can move forward and backward. The passage 91a communicates with the opening 92. As shown in fig. 6 and 8, the passage 91a is formed with a tapered portion 91b that narrows so as to guide the frame 29 from the printing portion 22 to a predetermined storage position. Specifically, as shown in fig. 6, the tapered portion 91b is provided at the front end 91c and the side surface 91d of the shelf portion 91. The cover member 93 is attached to the upper surface of the holder main body 90 a. As shown in fig. 9, the cover member 93 is used to block the gap G between the holder main body 90a and the passage opening 19 when the frame 29 is replaced between the holding holder 90 and the printing apparatus 11. The thickness of the cover member 93 is set to a thickness such that the operator's finger does not enter the gap G when the replaceable component is replaced between the uppermost shelf portion 91 in the housing bracket 90 and the printing apparatus 11 at the replacement position, for example, the gap G is 5[ mm ] or less. The housing bracket 90 does not have a driving part or a lifting part for moving the frame 29. The housing bracket 90 can be further simplified in structure. The shelf portion 91 has a size corresponding to the frame size of various exchangeable components. That is, the shelf 91 is formed to have a size capable of accommodating the largest frame 29. The housing bracket 90 may have a plurality of shelf portions 91 corresponding to the sizes of the housings of the various exchangeable members, or may have a plurality of shelf portions 91 having the same size as one housing bracket 90. In the latter case, a plurality of housing brackets 90 having the same outer shape may be prepared, and the shelf portion 91 of each housing bracket 90 corresponds to any one of the frame sizes of the various exchangeable components. In this case, although the types of the housing brackets 90 are increased, the outer dimensions of the housing brackets 90 are the same even if the corresponding frame sizes of the exchangeable members are different, and thus the receiving portions 42 and 62 can be shared by the housing brackets 90.

The management PC80 is a device that manages information of each device of the installation system 10. The management PC80 includes a management control unit 81, a storage unit 82, and a communication unit 83. The management control unit 81 is configured as a microprocessor centering on a CPU, and controls the entire apparatus. When acquiring the request information requesting the movement of the storage rack 90 from the printing apparatus 11, the management control unit 81 outputs a command for moving the storage rack 90 to the automated guided vehicle 18 that carries the storage rack 90 to the control PC or the automated guided vehicle 18 in the warehouse area 15. The storage unit 82 is a large-capacity storage medium such as an HDD or a flash memory, and manages progress status of each device on the mounting line, components transported by the automated guided vehicle 18, a current position, and the like. The communication unit 83 is an interface used when communicating with an external device. Each device of the installation system 10 exchanges information with the management PC80 via the communication unit 83.

First, a printing process of the printing apparatus 11 configured as described above will be described. The print processing routine for performing the print processing is stored in the storage unit of the print control unit 21, and is executed after the print control unit 21 inputs an execution instruction of the print processing by the operator. When the printing process routine is started, the CPU of the printing control unit 21 first performs a process of conveying, fixing, and raising the substrate S by the substrate processing unit 30 so as to bring the substrate S into contact with the screen mask M. At this time, the CPU adjusts the position of the screen mask M by the mask working unit 26, and performs alignment of the pattern hole with the substrate S. Next, the CPU moves the cartridge 36 onto the screen mask M, causing it to eject solder. Next, the CPU moves the print head 23, lowers the squeegee 25 to bring the squeegee 25 into contact with the upper surface of the screen mask M, and moves the squeegee 25 in the front-rear direction to print the solder on the substrate S. In this way, the print control unit 21 performs a printing process including a substrate conveyance fixing process, a solder supply process, and a squeegee movement process, and prints on the substrate S. The CPU repeats the printing process while replacing the screen mask M until the production process of all types of substrates S in the production plan is completed.

Next, the operation of the replacement unit 40 will be described with reference to fig. 11 to 17. Here, replacement of the screen mask M by the replacement unit 40 will be described. The housing bracket 90 has one or more empty shelf portions 91, and the shelf located at the uppermost layer of the shelf portions 91 houses and holds the frame 29 of the screen mask M used in the printing apparatus 11. Fig. 11 is a flowchart showing an example of a component replacement processing routine executed by the replacement control section 70 of the replacement unit 40. Fig. 12 is an explanatory view showing a case where the housing bracket 90 is pulled into the housing 29, and fig. 13 is an explanatory view showing a relationship between the height of the housing 29 and the height of the shelf 91 at the replacement position. Fig. 14 is an explanatory view showing a case where the housing bracket 90 is pulled into the housing 29. Fig. 15 is an explanatory view showing a case where the housing bracket 90 is sent out of the housing 29. Fig. 16 is an explanatory diagram showing the relationship between the height of the shelf 91 and the frame 29 at the replacement position. Fig. 17 is an explanatory view showing a case where the housing bracket 90 is sent out of the housing 29. The component replacement processing routine is stored in the storage unit of the replacement control unit 70, and is executed after a frame replacement instruction is input from the print control unit. When this routine is started, first, as shown in fig. 12 a, the CPU of the replacement control unit 70 drives the driving units 43 and 63 so that the empty shelf 91 is at a predetermined lower-level replacement position, and lifts and lowers the storage bracket 90 (S100). Specifically, as shown in fig. 13, the CPU of the replacement control unit 70 controls the driving units 43 and 63 to raise and lower the housing bracket 90 so that the height of the empty shelf 91 is lower than the passing surface 20 through which the frame 29 passes when the frame 29 is pulled into the empty shelf 91.

Next, the CPU outputs a conveyance instruction to the printing apparatus 11. When the send-out instruction is input, the CPU of the print control section 21 controls various components so as to convey the frame 29 to a predetermined position. Specifically, as shown in fig. 12 (B), the CPU of the print control unit 21 lowers the replacement unit 27, and brings the replacement unit 27 into contact with the frame 29 holding the screen mask M. Next, the CPU of the print control unit 21 controls the print moving unit 24 to convey the frame 29 together with the print head 23. Next, when a signal indicating that the housing 29 has been conveyed to a predetermined position from a sensor not shown and that the housing 29 has entered the shelf portion 91 of the housing bracket 90 is inputted, the CPU of the print control unit 21 controls the print moving unit 24 to stop the print head 23. Then, the CPU of the print control section 21 outputs a pull-in instruction to the replacement control section 70.

Next, the CPU of the replacement control unit 70 inputs a pull-in command output from the print control unit 21 (S120), and executes a pull-in process of the housing 29 (S130). Specifically, as shown in fig. 14 (a), the CPU controls the moving unit 46 to insert the feeding unit 45 into the insertion space 95 provided in the holder main body 90a, to bring the front surface 47a of the belt 47 into contact with the frame 29, and to press the frame 29 against the driven unit 94 provided on the side surface of the right shelf 91. Then, the CPU controls the driving unit 48 to rotate the belt 47 in a direction to draw the housing 29 into the empty housing holder 90. Then, the housing 29 is pulled into the housing holder 90 by friction force of the surface 47a of the belt 47, and as shown in fig. 12 (C) and 14 (B), the housing 29 is housed in the shelf 91. Then, as shown in fig. 14 (C), the CPU controls the moving unit 46 to pull out the feeding unit 45 from the insertion space 95.

Next, as shown in fig. 15 a, the CPU controls the driving units 43 and 63 so that the shelf 91 in which the frame 29 holding the screen mask M used in the printing apparatus 11 is accommodated is at a predetermined upper height replacement position (S140). Specifically, as shown in fig. 16, the CPU of the replacement control unit 70 controls the driving units 43 and 63 to raise and lower the housing bracket 90 so that the height of the shelf 91 housing the housing 29 to be used next reaches a position higher than the passing surface 20 through which the housing 29 passes when the housing bracket 90 feeds the housing 29.

Next, the CPU executes the component feed-out process (S150). Specifically, as shown in fig. 17 (a), the CPU controls the moving unit 46 to insert the feeding unit 45 into the insertion space 95 provided in the holder main body 90a, to bring the front surface 47a of the belt 47 into contact with the frame 29, and to press the frame 29 against the driven unit 94 provided on the side surface of the right shelf 91. Then, the CPU controls the driving unit 48 to rotate the belt 47 in a direction to send the housing 29 to the printing apparatus 11. Then, the frame 29 is sent out to the printing apparatus 11 by the friction force of the surface 47a of the belt 47 as shown in fig. 17 (B). Then, the CPU determines whether or not the frame 29 is conveyed to the predetermined position based on the amount of movement of the frame by the driving unit 48 from the start of the frame being sent to the printing apparatus 11 by the driving unit 48 to the current time point, and when the frame 29 is conveyed to the predetermined position, controls the driving unit 48 to stop the rotation of the belt 47. Then, the CPU controls the moving unit 46 to pull out the feeding unit 45 from the insertion space 95 as shown in fig. 17 (C).

Then, the CPU outputs a send-out instruction to the printing apparatus 11 (S160). When the send-out instruction is input, the CPU of the print control section 21 controls various components so as to convey the frame 29 holding the screen mask M to a fixed position. Specifically, the CPU of the print control unit 21 controls the replacement unit 27 so that the replacement unit 27 comes into contact with the housing 29. Next, the CPU of the print control unit 21 controls the print moving unit 24 to convey the frame 29 together with the print head 23. Then, when the frame 29 is conveyed to the fixed position, the CPU of the print control unit 21 controls the print moving unit 24 to stop the print head 23. After S160, the CPU of the replacement control section 70 ends the present routine.

Here, the correspondence between the constituent elements of the present embodiment and the constituent elements of the present disclosure is clarified. The replacement unit 40 of the present embodiment corresponds to a replacement unit, the printing unit 22 corresponds to a printing unit, the printing apparatus 11 corresponds to a printing apparatus, the receiving units 42 and 62 correspond to receiving units, the housing bracket 90 corresponds to a housing bracket, the replacement unit 44 corresponds to a replacement unit, and the left unit 41 and the right unit 61 correspond to a lifting unit. In addition, the printing system 12 corresponds to a printing system.

The replacement unit 40 according to the present embodiment described above includes: the replacement unit 44 is configured to replace the replaceable component by abutting against and driving the frame 29 between the shelf unit 91 of a predetermined height of the housing bracket 90 disposed in the receiving units 42 and 62 and the printing apparatus 11; and a lifting part for moving the housing bracket 90 up and down. Therefore, the replacement unit 44 and the driving units 43 and 63 do not need to be provided in the housing bracket 90. Accordingly, the housing bracket 90 can be made compact when the replaceable component used in the printing apparatus 11 is automatically replaced.

The replacement unit 40 includes a pair of left and right units 41 and 61, and the replacement unit 44 provided in the left unit 41 includes: the feeding section 45 includes a belt 47 for moving the frame 29 toward the printing apparatus 11 or the housing bracket 90 by friction force of the surface 47a, and a driving section 48 for rotating the belt 47; and a moving unit 46 that moves the feeding unit 45 so that a surface 47a of the belt 47 of the feeding unit 45 approaches or separates from the housing 29. Therefore, the replacement unit 40 can have a relatively simple structure. Further, an insertion space 95 into which the delivery unit 45 of the replacement unit 44 is inserted is provided in a side surface of the housing bracket 90, and the replacement unit 44 inserts the delivery unit 45 into the insertion space 95 to replace the replaceable component. Therefore, in the replacement unit 40, the tape 47 is brought into contact with the casing 29 by inserting the delivery unit 45 into the insertion space 95, and the driving unit 48 is driven, so that the casing 29 can be replaced. Thus, in the replacement unit 40, replacement of the replaceable component can be performed relatively easily.

The replacement unit 40 further includes a replacement control unit 70, and the replacement control unit 70 controls the replacement unit 44 so that the frame 29 conveyed from the printing apparatus 11 is pulled into the shelf 91 when a pull-in command is received from the printing apparatus 11 after the frame 29 enters the shelf 91. Therefore, in the replacement unit 40, the replaceable component can be smoothly replaced between the printing apparatus 11 and the housing bracket 90.

The replacement unit 40 further includes a replacement control unit 70, and the replacement control unit 70 controls the replacement unit 44 to send the housing 29 to the printing apparatus 11, and then outputs a send-out command to the printing apparatus 11. Therefore, in the replacement unit 40, the replaceable component can be smoothly replaced between the printing apparatus 11 and the housing bracket 90.

The replacement unit 40 further includes a replacement control unit 70, and the replacement control unit 70 controls the driving units 43 and 63 so that the shelf unit 91 is moved to a position higher than the passing surface 20 of the printing apparatus 11 when the housing 29 is fed from the housing bracket 90, and the shelf unit 91 is moved to a position lower than the passing surface 20 when the housing 29 is pulled from the printing apparatus 11. Therefore, in the replacement unit 40, when the housing bracket 90 and the printing apparatus 11 are replaced, the housing 29 can be made difficult to be caught by the printing apparatus 11 and the shelf 91.

The printing apparatus 11 is provided with the replacement unit 40, and includes a tapered portion 19a, and the tapered portion 19a is provided in a passage opening 19 through which the frame 29 passes when the frame 29 is moved between the printing apparatus 11 and the housing bracket 90, and guides the frame 29 to a fixed position when the frame 29 is subjected to a printing process by the printing portion 22. Therefore, in the printing apparatus 11, when the housing 29 is carried into the printing apparatus 11 from the housing bracket 90, the housing 29 is difficult to be caught by the printing apparatus 11.

The housing holder 90 is a housing holder that can be housed in the replacement unit 40 provided in the printing apparatus 11, and the printing apparatus 11 includes the printing unit 22 that performs printing processing of viscous fluid on the processing target by using the screen mask M. The housing bracket 90 further includes: a holder main body 90a formed with an opening 92 through which the frame 29 passes when the frame supporting the exchangeable member including the screen mask M is exchanged between the housing holder 90 and the printing apparatus 11; a plurality of shelf portions 91 disposed inside the holder main body 90a and accommodating the frame 29; and a tapered portion 91b formed in the opening 92, the passage 91a being formed so as to narrow the housing 29 so as to guide the housing to the housing position of the shelf portion 91. Therefore, in the printing apparatus 11, when the housing is carried out to the housing bracket 90, the housing 29 is difficult to be caught by the housing bracket 90.

In the housing bracket 90, the tapered portion 91b may be formed on both the side surface 91d side of the shelf portion 91 and the front end 91c of the shelf portion 91. Therefore, in the housing bracket 90, when the frame 29 is carried out from the printing apparatus 11 to the housing bracket 90, the frame 29 is less likely to be caught by the housing bracket 90.

In the housing bracket 90, the replacement unit 40 is constituted by a pair of left side units 41 and right side units 61, and the left side unit 41 includes a replacement unit 44, and the replacement unit 44 includes: the feeding section 45 includes a belt 47 for moving the frame 29 toward the printing apparatus 11 or the housing bracket 90 by friction force of the surface 47a, and a driving section 48 for driving the belt 47; and a moving unit 46 that moves the feeding unit 45 so that a surface 47a of the belt 47 of the feeding unit 45 approaches or separates from the housing 29. The holder main body 90a is formed with an insertion space 95 into which the delivery unit 45 of the replacement unit 44 is inserted, and the shelf unit 91 includes a follower 94 that follows the movement of the housing 29 when the delivery unit 45 abuts against the housing 29. The driven portion 94 is formed, for example, as a ball cast. Therefore, in the housing bracket 90, when the housing 29 is fed out by the feeding-out portion 45 or the housing 29 is pulled into the shelf portion 91, friction between the housing 29 and the shelf portion 91 can be reduced. This allows the housing bracket 90 to be smoothly replaced with the housing 29.

The printing system 12 further includes a replacement unit 40, a printing device 11, and a housing bracket 90. Since the printing system 12 includes the replacement unit 40, the housing bracket 90 can be made compact when automatically replacing the replaceable components used in the printing apparatus 11, as in the replacement unit 40.

For example, the replacement unit 44 may be configured by a rubber roller and a driving unit 48 connected to the rubber roller to rotate the rubber roller, and the driving unit 48 may be driven to rotate the rubber roller in a state where the surface of the rubber roller is brought into contact with the housing 29, so that the housing 29 is sent out from the housing bracket 90 or the housing 29 is pulled into the housing bracket 90.

In the above embodiment, the tapered portion 19a, which is a member having a tapered surface, is disposed in the passage port 19, but the guide 26a may be omitted and the tapered portion may be formed. That is, the guide 26a may have a tapered surface. In the printing apparatus 11, the movement of the housing 29 can be smoothly performed. Alternatively, the printing device 11 may not have the tapered portion 19a. In the printing apparatus 11, the replacement unit 44 can be used to simplify the structure of the housing bracket 90. In the printing apparatus 11 having the tapered portion 19a, it is preferable that the frame 29 move smoothly.

In the above embodiment, the housing bracket 90 has the tapered portion 91b in the opening 92 of the shelf portion 91, but the present invention is not limited thereto, and the tapered portion 91b may be omitted. In the housing bracket 90, the replacement part 44 can be used to simplify the structure of the housing bracket 90. In addition, in the housing bracket 90 having the tapered portion 91b, it is preferable that the movement of the frame 29 be smooth.

In the above embodiment, the insertion space 95 is a groove-shaped space formed at the position of each shelf portion 91 on the side surface of the holder main body 90a facing the left unit 41, but is not particularly limited thereto. For example, the insertion space 95 may be a space having a shape in which two or more groove-like insertion spaces 95 communicate in the vertical direction.

In the above embodiment, the printing apparatus 11 outputs the pull-in command and the replacement unit 40 outputs the send-out command, but the present invention is not limited to this, and one or more of these commands may be omitted. For example, these instructions can be omitted by providing the printing apparatus 11 with a detection sensor for detecting the housing 29, or providing the replacement unit 40 with a detection sensor for detecting the housing 29. In addition, in the printing system 12, no detection sensor is provided, enabling simplification of the structure.

In the above embodiment, in the printing system 12, the replacement unit 40 has the replacement unit 44 including the driving unit 48, the moving unit 46, and the sending-out unit 45, but is not limited thereto, and the frame 29 may be movable. The printing system 12 includes a tapered portion 19a and a tapered portion 91b. In the printing system 12, since each tapered portion is provided, the movement of the frame 29 can be made smoother.

In the above embodiment, the receiving portions 42 and 62 support the left and right end portions of the housing bracket 90 from the lower surface side to receive the housing bracket 90, but the receiving portions are not particularly limited to this as long as the housing bracket 90 can be received, and for example, the entire lower surface of the housing bracket 90 may be supported, or the housing bracket 90 may be supported from the side surfaces and the upper surface of the housing bracket 90 to be received. In the above embodiment, the replacement unit 40 receives the storage rack 90 from the automated guided vehicle 18 by lifting the storage rack 90 upward, and transfers the storage rack 90 to the automated guided vehicle 18 by removing the storage rack 90 downward, but the present invention is not limited thereto as long as the storage rack 90 can be received and transferred. The automated guided vehicle 18 enters the lifting space 50 to receive and transfer the storage rack 90, but is not particularly limited thereto. For example, a conveyor or the like may be provided in any one of the mounting portion and the receiving portions 42, 62 of the automated guided vehicle 18, and the automated guided vehicle 18 may be stopped before the replacement of the unit 40 to receive and transfer the storage rack 90.

In the above embodiment, the replacement portion 27 has a lever structure having an abutting portion arranged on the print head 23, but is not limited to this, and may be a separate mechanism arranged outside the print head 23. In the above embodiment, the replacement part 27 is a lever mechanism engaged with the housing 29, but may be a conveying mechanism that moves the housing 29 including the replaceable component by being placed thereon, for example.
