[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, the storage device in the above-described printing system is provided with a lifting portion that has a plurality of stages of placement portions that place replaceable components in the up-down direction and moves the placement portions to a replacement position in the up-down direction, and an object moving portion that grips a replaceable component at the replacement position and automatically replaces the replaceable component with the printing device. Therefore, the storage device itself is large. If such a storage device is disposed on the front surface of the printing device, it is difficult for an operator to perform work on the front surface of the printing device.

[0008] The present disclosure was achieved in view of such a problem, and a main object thereof is to provide a replacement unit, a printing device, a storage rack, and a printing system that enable compactification of the storage rack when automatically replacing a replaceable component used by the printing device.

[0009] TECHNICAL SOLUTION FOR SOLVING THE PROBLEM

[0010] The replacement unit of the present disclosure is provided in a printing device that is provided with a printing portion that performs printing processing of a viscous fluid on a processing object using a screen mask, and the replacement unit is provided with a receiving portion that receives a storage rack that has a plurality of shelf portions that house a frame that supports a replaceable component including the screen mask, a replacement portion that replaces the replaceable component by abutting against and driving the frame between the shelf portion of the storage rack disposed at a predetermined height in the receiving portion and the printing device, and a lifting portion that moves the storage rack up and down.

[0011] The replacement unit includes: a replacement section that replaces replaceable parts by abutting against and driving a shelf portion at a predetermined height on a receiving bracket between the receiving section and the printing apparatus; and a lifting section that moves the receiving bracket up and down. Therefore, it is unnecessary to install the replacement section and the lifting section on the receiving bracket. Consequently, the receiving bracket can be made more compact when automatically replacing replaceable parts used in the printing apparatus. Attached Figure Description

[0030] ​​The warehouse area 15 is an area in which replaceable components (hereinafter also simply referred to as components) and the like to be used in the mounting system 10 are prepared. As the components to be used in the mounting system 10, for example, a screen mask M, a support component 32 that holds a processing target, a squeegee 25 that applies solder paste as an adhesive fluid in a printing process, a cartridge 36 that houses an adhesive fluid, a cleaning component 34 that cleans the screen mask M, and the like are exemplified in the printing device 11. The arm robot 16 and a preparation table 17 are provided in this warehouse area 15. The arm robot 16 performs a work of carrying a housing rack 90 prepared for next use from the preparation table 17 to the automated guided vehicle 18, and a work of moving a used housing rack 90 recovered by the automated guided vehicle 18 to the preparation table 17. The preparation table 17 is a work table on which a new housing rack 90, a used housing rack 90 is placed. The arm robot 16 is controlled by a control PC not shown. The control PC receives a replacement instruction from the management PC 80 via a network line, and outputs information on a work state of the arm robot 16 and the like to the management PC 80. Further, in the warehouse area 15, the movement and preparation of the housing rack 90 can also be performed by an operator.

[0031] The mounting device 13 is a device that mounts components to a substrate S on which an adhesive fluid such as solder paste is printed by the printing device 11.

[0032] The automated guided vehicle 18 moves between the warehouse area 15 that stores components related to mounting processes and performs preparation for use and the mounting line, and automatically carries a housing rack 90 that houses components such as the screen mask M, for example. The more unit 40 that receives the housing rack 90 is connected to the printing device 11, and the automated guided vehicle 18 hands over the carried housing rack 90 to the more unit 40. The automated guided vehicle 18 can be an AGV that moves along a line formed on the ground or the like, or an AMR that autonomously travels based on a signal obtained from a sensor, a camera, or the like. The automated guided vehicle 18 is provided with a controller, a drive unit, a communication unit, and a placement unit. The controller controls the entire device. The drive unit is a motor that drives wheels to be rotated, and is controlled by the controller. The communication unit is a wireless interface that communicates with external devices such as the printing device 11 and the management PC 80. The automated guided vehicle 18 transmits and receives instructions and signals between the management PC 80 and the printing device 11 via the communication unit. The automated guided vehicle 18 has the placement unit on the upper surface thereof, on which components such as the housing rack 90 are placed. The automated guided vehicle 18 enters the lift space 50 formed in the center of the more unit 40, and performs reception and handover of the housing rack 90 between the more unit 40.

[0033] As Figure 1 , Figure 2 , Figure 10As shown, the printing device 11 is a device that applies (prints) solder, which is a viscous fluid, to a substrate S, which is a processing target below, by pressing the solder on the screen mask M into the pattern holes formed in the screen mask M using the squeegee 25. Here, as the "processing target", for example, a substrate S for component mounting, a base material that is a three-dimensional object, and the like are cited. As the "viscous fluid", solder paste, conductive paste, adhesive, and the like are cited. Here, the substrate S and the solder are exemplified below. 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 part 91 of the accommodation rack 90 (refer to Figure 1 ). As shown in Figure 10 , the printing device 11 is provided with a printing control part 21, a printing part 22, a mask operation part 26, a substrate processing part 30, a cleaning part 33, and a supply part 35.

[0034] The printing control part 21 is configured as a microprocessor centered on a CPU, and controls the entire printing device 11. The printing control part 21 outputs and inputs signals to and from the management PC 80, which is an external device, in addition to the printing part 22, the mask operation part 26, the substrate processing part 30, the cleaning part 33, the supply part 35, and the exchange unit 40. For example, the printing control part 21 outputs request information that requests movement of the accommodation rack 90 to the management PC 80, which is a management device, in accordance with the usage state of the replaceable parts in the printing part 22. In addition, the printing control part 21 inputs a reception signal that the accommodation rack 90 is fitted to the main body of the exchange unit 40 from the automated guided vehicle 18. In addition, the printing control part 21 controls the first exchange part 27 so as to exchange the screen mask M between the accommodation rack 90 and the printing part 22. This printing control part 21 has a storage part that stores information of the substrate S on which printing processing is performed, a printing processing program that performs printing processing on the substrate S, a component exchange processing program that performs exchange processing of the frame 29 based on the first exchange part 27, and the like.

[0035] The printing part 22 is provided at the upper stage of the printing device 11, and is a unit that performs printing processing of a viscous fluid on a substrate S using a screen mask M. As shown in Figure 1 , Figure 4 , the printing part 22 is provided with a print head 23, a printing movement part 24, a squeegee lifting part, a squeegee 25, and a through port 19. The printing movement part 24 moves the print head 23 in a predetermined printing direction (here, the front-rear direction), and is provided with a guide formed in the front-rear direction, a slide that moves along the guide, and a motor that drives the slide. The squeegee 25 is provided on the lower surface side of the print head 23, and is lifted and lowered by the squeegee lifting part. The printing part 22 has two squeegees 25 that are used in the front-rear direction, respectively. A wall part of the housing of the printing device 11 at the front face is provided with a through port 19 through which the frame 29 can pass. As shown in Figure 3As shown, a first tapered portion 19a is formed along the guide member 26a of the mask working section 26 at the passage 19 to guide the frame 29 to a fixed position behind the fixed frame 29. The first tapered portion 19a has a tapered surface that narrows towards the fixed position from the passage of the frame 29, and is disposed on both sides of the passage 19. Figure 2 As shown, the mask processing unit 26 is disposed vertically between the printing unit 22 and the substrate processing unit 30, and is a unit for fixing and holding the screen mask M. Figure 10 As shown, the mask operation unit 26 includes a first replacement unit 27 and a mask fixing unit 28. The first replacement unit 27 is a transport rod provided on the printing head 23, which is lowered to a position abutting against the screen mask M by a cylinder (not shown), and the contact part abutting against the frame 29 is also moved in the back-and-forth direction by rotation (see reference). Figure 2 (Dash line). The print head 23 and the first replacement part 27 engage with the frame 29 between the shelf part 91 and the printing part 22 at a predetermined height of the receiving bracket 90, causing the frame 29 to move. The mask fixing part 28 positions the screen mask M and supports and fixes it in a horizontal position. The screen mask M is pressed by the first replacement part 27 and moves back and forth along the guide of the mask working part 26, and is fixed by the mask fixing part 28. Figure 2 As shown, the substrate processing unit 30 is disposed below the mask processing unit 26 and is a unit for loading the substrate S, positioning and supporting the loaded substrate S to allow it to contact and separate from the screen mask M. The substrate processing unit 30 includes: a substrate transport unit 31 for transporting the substrate S in a left-right direction; a support member 32 for supporting the substrate S from below; and a substrate lifting unit for lifting the entire substrate processing unit 30 and the support member 32. The cleaning unit 33 is disposed vertically between the mask processing unit 26 and the substrate processing unit 30 and is a unit for cleaning the back side of the screen mask M. The cleaning unit 33 has a cleaning member 34 for cleaning the screen mask M. The supply unit 35 is a unit for supplying solder contained in a cartridge 36 to 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 the solder from the cartridge 36. Cleaning components 34 and box 36 are consumables and should be replaced as needed.

[0036] The replacement unit 40 is configured to receive and raise / lower a housing support 90 containing replaceable components such as a screen mask M fixed to the frame 29. The replacement unit 40 has a pair of left and right units 41, which serve as the lifting mechanism of this disclosure, and a replacement control unit 70. The replacement unit 40 has a lifting space 50 at the center of the left and right units 41 for raising and lowering the housing support 90.

[0037] The left unit 41 is disposed on the front left side of the frame of the printing apparatus 11. The left unit 41 includes a first receiving part 42, a first driving part 43, and a second replacement part 44. The first receiving part 42 receives a receiving bracket 90 that houses and supports the frame 29 of the screen mask M, and supports the receiving bracket 90 from the lower surface side. The first receiving part 42 may also fix the receiving bracket 90 by magnetic force, for example. The first driving part 43 raises and lowers the receiving bracket 90 by raising and lowering the first receiving part 42. The first driving part 43 may have a ball screw with a lifting shaft and a drive motor, or it may be a linear motor. The second replacement part 44 is driven by abutting against the frame 29, thereby replacing the frame 29 between the receiving bracket 90 and the printing part 22. The second replacement part 44 includes a delivery part 45 and a moving part 46. The delivery part 45 includes a belt 47 that moves the frame 29 toward the printing apparatus 11 or the receiving bracket 90 by the friction of the surface 47a, and a second driving part 48 that rotates the belt 47. The second drive unit 48 is configured as, for example, a servo motor. Figure 4 As shown, the delivery unit 45 is configured to transmit power from the second drive unit 48 to the belt 47 via a plurality of pulleys 49. The moving unit 46 is used to move the delivery unit 45 in a direction (in this case, left-right) relative to the frame 29 housed in the housing support 90, such as a cylinder or a linear motor.

[0038] The right-side unit 61 has a second receiving section 62. The right-side unit 61 is disposed on the front right side of the housing of the printing apparatus 11. The right-side unit 61 includes the second receiving section 62 and the third driving section 63. Furthermore, the second receiving section 62 and the third driving section 63 are the same as the first receiving section 42 and the first driving section 43, so their description is omitted.

[0039] The replacement control unit 70 is configured as a CPU-centric microprocessor that controls the entire replacement unit 40. The replacement control unit 70 outputs signals to the first drive unit 43, the third drive unit 63, and the printing control unit 21. Additionally, the replacement control unit 70 receives signals from the printing control unit 21. This replacement control unit 70 performs the process of moving the receiving bracket 90 from the raiseable position to the replacement position using the first drive unit 43. Furthermore, when the replacement of the replaceable component is completed, the replacement control unit 70 lowers the receiving bracket 90 from the replacement position to the raiseable position (the first receiving unit 42 and the second receiving unit 62 lower to their lowest positions) via the first drive unit 43.

[0040] The housing support 90 is a housing for the housing frame 29, which supports the screen mask M, a replaceable component related to the printing process performed by the printing unit 22. Figure 2 , Figures 5 to 8 As shown, the housing support 90 has a support body 90a, an opening 92, multiple shelf portions 91, and a cover component 93.Figure 5 、 Figure 6 As shown in FIG. 10, an insertion space 95 is provided in the rack main body 90a for insertion of the delivery portion 45 of the second replacement unit 44 when the replaceable unit is replaced between the housing rack 90 and the printing device 11. The insertion space 95 is a groove-shaped space formed in the position of each shelf portion 91 on the side opposite to the left unit 41. The insertion space 95 is formed in the side surface of the single side of the rack main body 90a. The opening portion 92 is in communication with the outside through the passage 19 of the printing portion 22, and the frame 29 is carried in and carried out through the opening portion 92. The shelf portion 91 houses the frame 29 in the predetermined housing position. The rack main body 90a has the shelf portions 91 on the left and right for insertion of the end portions of the frame 29 and support of the frame 29. The shelf portions 91 are arranged at predetermined intervals in the up-and-down direction in a manner that the frame 29 on which the screen mask M is supported can be placed in the up-and-down direction. The shelf portion 91 is a member having a substantially L-shaped cross-sectional shape. The left shelf portion 91 has a driven portion 94 mounted on the support surface of the frame 29 to support the frame 29 driven by the movement of the frame 29. The driven portion 94 is mounted on the support surface and the side surface of the right shelf portion 91. The driven portion 94 is, for example, a ball roller. Alternatively, the driven portion 94 can be a carrying roller. Between the left and right shelf portions 91, the frame 29 is a passage 91a that can move forward and backward. The passage 91a is in communication with the opening portion 92. As shown in FIG. 11, the passage 91a is formed with a second tapered portion 91b that narrows in a manner to guide the frame 29 from the printing portion 22 to the predetermined housing position. Figure 6 、 Figure 8 As shown in FIG. 10, an insertion space 95 is provided in the rack main body 90a for insertion of the delivery portion 45 of the second replacement unit 44 when the replaceable unit is replaced between the housing rack 90 and the printing device 11. The insertion space 95 is a groove-shaped space formed in the position of each shelf portion 91 on the side opposite to the left unit 41. The insertion space 95 is formed in the side surface of the single side of the rack main body 90a. The opening portion 92 is in communication with the outside through the passage 19 of the printing portion 22, and the frame 29 is carried in and carried out through the opening portion 92. The shelf portion 91 houses the frame 29 in the predetermined housing position. The rack main body 90a has the shelf portions 91 on the left and right for insertion of the end portions of the frame 29 and support of the frame 29. The shelf portions 91 are arranged at predetermined intervals in the up-and-down direction in a manner that the frame 29 on which the screen mask M is supported can be placed in the up-and-down direction. The shelf portion 91 is a member having a substantially L-shaped cross-sectional shape. The left shelf portion 91 has a driven portion 94 mounted on the support surface of the frame 29 to support the frame 29 driven by the movement of the frame 29. The driven portion 94 is mounted on the support surface and the side surface of the right shelf portion 91. The driven portion 94 is, for example, a ball roller. Alternatively, the driven portion 94 can be a carrying roller. Between the left and right shelf portions 91, the frame 29 is a passage 91a that can move forward and backward. The passage 91a is in communication with the opening portion 92. As shown in FIG. 11, the passage 91a is formed with a second tapered portion 91b that narrows in a manner to guide the frame 29 from the printing portion 22 to the predetermined housing position. Figure 6 , Figure 9As shown, the cover member 93 is used to block the gap G between the housing rack 90 and the printing device 11 when the frame 29 is replaced between the housing rack 90 and the printing device 11. The thickness of the cover member 93 is set to a thickness that does not allow the fingers of the operator to enter the gap G when replacing the replaceable member between the uppermost shelf portion 91 in the housing rack 90 at the replacement position and the printing device 11, for example, a thickness of 5 [mm] or less. The housing rack 90 does not have a drive portion that moves the frame 29, or a lifting portion. In the housing rack 90, the structure can be further simplified. The shelf portion 91 has a size corresponding to the frame size of each replaceable member. That is, the shelf portion 91 is formed to have a size that can accommodate the largest frame 29. The housing rack 90 can have a plurality of shelf portions 91 each having a size corresponding to the frame size of each replaceable member, or can have a plurality of shelf portions 91 each having the same size. In the latter case, a plurality of housing racks 90 each having the same size can be prepared, and the shelf portion 91 of each housing rack 90 can correspond to any one of the frame sizes of the replaceable members. In this case, although the number of types of housing racks 90 increases, the size of each housing rack 90 is the same even if the frame size of the corresponding replaceable member is different, and thus each housing rack 90 can share the first receiving portion 42 and the second receiving portion 62.

[0041] The management PC 80 is a device that manages information of each device of the installation system 10. The management PC 80 is provided with a management control portion 81, a storage portion 82, and a communication portion 83. The management control portion 81 is configured as a microprocessor centered on a CPU, and controls the entire device. When the management control portion 81 acquires request information requesting movement of the housing rack 90 from the printing device 11, the management control portion 81 outputs an instruction to move the automated guided vehicle 18 that carries the housing rack 90 to the control PC of the warehouse area 15 and the automated guided vehicle 18. The storage portion 82 is a large-capacity storage medium such as a HDD or a flash memory, and manages the progress status of each device of the installation line, the parts carried by the automated guided vehicle 18, the current position, and the like. The communication portion 83 is an interface used when communicating with an external device. Each device of the installation system 10 exchanges information with the management PC 80 via the communication portion 83.

[0042] First, the printing process of the printing apparatus 11 thus configured will be described. A printing process routine for performing the printing process is stored in the storage section of the printing control section 21, and is executed after the execution instruction of the printing process is input from the operator. When the printing process routine is started, the CPU of the printing control section 21 first performs the process of carrying and fixing the substrate S by the substrate handling section 30 and raising it so that the substrate S abuts against the screen mask M. At this time, the CPU adjusts the position of the screen mask M by the mask handling section 26, and performs the alignment of the pattern holes and the substrate S. Next, the CPU moves the cassette 36 to the screen mask M, and causes it to eject solder. Next, the CPU moves the printing head 23, and causes the squeegee 25 to abut against the upper surface of the screen mask M by lowering the squeegee 25, and moves the squeegee 25 in the front and back directions to print the solder on the substrate S. In this way, the printing control section 21 performs the printing process including the substrate carrying and fixing process, the solder supply process, and the squeegee moving process, and performs printing on the substrate S. The CPU repeats this printing process while replacing the screen mask M, until the production process of all types of substrates S in the manufacturing plan is completed.

[0043] Next, the use of the Figures 11 to 17 The operation of the replacement unit 40 will be described. Here, the replacement of the screen mask M based on the replacement unit 40 will be described. Further, the housing rack 90 has one or more empty shelf sections 91, and the shelf section 91 located at the uppermost layer houses and holds the frame 29 of the screen mask M used in the printing apparatus 11. Figure 11 is a flowchart showing one example of the component replacement process routine executed by the replacement control section 70 of the replacement unit 40. Figure 12 is an explanatory diagram showing the case where the housing rack 90 is pulled into the frame 29, Figure 13 is an explanatory diagram showing the relationship between the height of the frame 29 at the replacement position and the shelf section 91. Figure 14 is an explanatory diagram showing the case where the housing rack 90 is pulled into the frame 29. Figure 15 is an explanatory diagram showing the case where the housing rack 90 is ejected from the frame 29. Figure 16 is an explanatory diagram showing the relationship between the height of the frame 29 at the replacement position and the shelf section 91. Figure 17 is an explanatory diagram showing the case where the housing rack 90 is ejected from the frame 29. Further, the component replacement process routine is stored in the storage section of the replacement control section 70, and is performed after the frame replacement instruction is input from the printing control section. When this routine is started, first, as shown in (A) of Figure 12 of FIG. 10, the CPU of the replacement control section 70 drives the first drive section 43 and the third drive section 63 in such a manner that the empty shelf section 91 becomes the replacement position at the predetermined lower height, and raises the housing rack 90 (S100). Specifically, as shown in Figure 13As shown, the CPU of the replacement control unit 70 controls the first drive unit 43 and the third drive unit 63 to raise and lower the receiving bracket 90 so that when the frame 29 is pulled into the empty shelf 91, the height of the empty shelf 91 reaches a position lower than the passage surface 20 through which the frame 29 passes.

[0044] Next, the CPU outputs a transport command to the printing unit 11. When the command is input, the CPU of the printing control unit 21 controls various components to transport the frame 29 to a predetermined position. Specifically, as follows... Figure 12 As shown in (B), the CPU of the printing control unit 21 lowers the first replacement unit 27, bringing it into contact with the frame 29 holding the screen mask M. Next, the CPU of the printing control unit 21 controls the printing movement unit 24, thereby moving the frame 29 together with the print head 23. Then, when a sensor (not shown) inputs a signal that the frame 29 has been moved to a predetermined position and that the frame 29 has entered the main body of the shelf portion 91 of the receiving bracket 90, the CPU of the printing control unit 21 controls the printing movement unit 24 to stop the print head 23. Then, the CPU of the printing control unit 21 outputs a pull-in command to the replacement control unit 70.

[0045] Next, the CPU of the control unit 70 inputs the pull-in command output by the printing control unit 21 (S120), and performs the pull-in process of the frame 29 (S130). Specifically, as follows... Figure 14 As shown in (A), the CPU controls the moving part 46 to insert the delivery part 45 into the insertion space 95 provided in the support body 90a, so that the surface 47a of the belt 47 abuts against the frame 29, and the frame 29 is pressed against the driven part 94 provided on the side of the shelf part 91 on the right side. Then, the CPU controls the second drive part 48 to rotate the belt 47 in the direction of pulling the frame 29 into the empty receiving bracket 90. Thus, the friction of the surface 47a of the belt 47 is used to pull the frame 29 into the receiving bracket 90, as... Figure 12 (C) Figure 14 As shown in (B), the frame 29 is housed within the shelf section 91. Then, as... Figure 14 As shown in (C), the CPU controls the moving part 46 to pull the sending part 45 out of the insertion space 95.

[0046] Next, as Figure 15 As shown in (A), the CPU controls the first drive unit 43 and the third drive unit 63 to change the shelf portion 91 of the frame 29, which houses the screen mask M used in the printing apparatus 11, to a predetermined upper height (S140). Specifically, as Figure 16As shown, the CPU of the replacement control unit 70 controls the first drive unit 43 and the third drive unit 63 to raise and lower the receiving bracket 90 so that when the frame 29 is sent out from the receiving bracket 90, the height of the shelf portion 91 that houses the frame 29 to be used next reaches a position higher than the passage surface 20 through which the frame 29 passes.

[0047] Next, the CPU executes the output processing of the unit (S150). Specifically, as follows... Figure 17 As shown in (A), the CPU controls the moving part 46 to insert the delivery part 45 into the insertion space 95 provided in the support body 90a, so that the surface 47a of the belt 47 abuts against the frame 29, and the frame 29 is pressed against the driven part 94 provided on the side of the shelf part 91 on the right side. Then, the CPU controls the second drive part 48 to rotate the belt 47 in the direction of delivering the frame 29 to the printing device 11. Thus, through the friction of the surface 47a of the belt 47, such as Figure 17 As shown in (B), the frame 29 is fed to the printing apparatus 11. Then, the CPU determines whether the frame 29 has been transported to a predetermined position based on the amount of movement caused by the second drive unit 48 from the moment the frame is fed to the printing apparatus 11 by the second drive unit 48 until the current time point. When the frame 29 has been transported to the predetermined position, the CPU controls the second drive unit 48 to stop the rotation of the belt 47. Then, the CPU controls the moving unit 46, as shown in (B). Figure 17 As shown in (C), the delivery part 45 is pulled out of the insertion space 95.

[0048] Then, the CPU outputs a send command to the printing apparatus 11 (S160). When the send command is input, the CPU of the printing control unit 21 controls various components to move the frame 29 holding the screen mask M to a fixed position. Specifically, the CPU of the printing control unit 21 controls the first replacement unit 27, causing the first replacement unit 27 to come into contact with the frame 29. Next, the CPU of the printing control unit 21 controls the printing movement unit 24, thereby moving the frame 29 together with the print head 23. Then, if the frame 29 is moved to the fixed position, the CPU of the printing control unit 21 controls the printing movement unit 24, thereby stopping the print head 23. After S160, the CPU of the replacement control unit 70 ends this routine.

[0049] Here, the correspondence between the constituent elements of this embodiment and the constituent elements of this disclosure is clarified. In this embodiment, the replacement unit 40 corresponds to the replacement unit, the printing unit 22 corresponds to the printing unit, the printing apparatus 11 corresponds to the printing apparatus, the first receiving unit 42 and the second receiving unit 62 correspond to the receiving unit, the housing support 90 corresponds to the housing support, the second replacement unit 44 corresponds to the replacement unit, and the left unit 41 and the right unit 61 correspond to the lifting unit. In addition, the printing system 12 corresponds to the printing system.

[0050] In the replacement unit 40 of the present embodiment described above, there are provided: a second replacement section 44 that replaces the replaceable component by abutting against the frame 29 and driving between the shelf section 91 provided at a predetermined height of the housing rack 90 of the first receiving section 42 and the second receiving section 62 and the printing device 11; and a lifting section that moves the housing rack 90 up and down. Therefore, it is not necessary to provide the second replacement section 44, the first driving section 43, and the third driving section 63 in the housing rack 90. Thus, when the replaceable component used by the printing device 11 is automatically replaced, it is possible to make the housing rack 90 compact.

[0051] In addition, the replacement unit 40 has a left side unit 41 and a right side unit 61 that are a pair of left and right units. The second replacement section 44 provided in the left side unit 41 has a feeding section 45 that has a belt 47 that moves the frame 29 to the printing device 11 side or the housing rack 90 side by the frictional force of a surface 47a and a second driving section 48 that rotates the belt 47, and a moving section 46 that moves the feeding section 45 in such a manner that the surface 47a of the belt 47 of the feeding section 45 approaches or separates from the frame 29. Therefore, in the replacement unit 40, it is possible to make the structure relatively simple. In addition, an insertion space 95 into which the feeding section 45 of the second replacement section 44 is inserted is provided in the side surface of the housing rack 90, and the second replacement section 44 replaces the replaceable component by inserting the feeding section 45 into the insertion space 95. Therefore, in the replacement unit 40, the feeding section 45 is inserted into the insertion space 95, the belt 47 is brought into abutment with the frame 29, and then the second driving section 48 is driven, so that it is possible to replace the frame 29. Thus, in the replacement unit 40, it is possible to replace the replaceable component relatively easily.

[0052] In addition, the replacement unit 40 has a replacement control section 70 that controls the second replacement section 44 so as to pull in the frame 29 toward the shelf section 91 when a pull-in instruction is received from the printing device 11 after the frame 29 transported from the printing device 11 enters the shelf section 91. Therefore, in the replacement unit 40, it is possible to replace the replaceable component smoothly between the printing device 11 and the housing rack 90.

[0053] In addition, the replacement unit 40 has a replacement control section 70 that outputs a feeding-out instruction to the printing device 11 after controlling the second replacement section 44 in such a manner that the frame 29 is fed out toward the printing device 11. Therefore, in the replacement unit 40, it is possible to replace the replaceable component smoothly between the printing device 11 and the housing rack 90.

[0054] Further, the exchange unit 40 is provided with an exchange control section 70 that controls the first drive section 43 and the third drive section 63 so as to move the shelf section 91 to a position higher than the passing face 20 of the printing device 11 when the frame 29 is sent out from the housing bracket 90, and to move the shelf section 91 to a position lower than the passing face 20 when the frame 29 is pulled in from the printing device 11. Therefore, in the exchange unit 40, when the exchange of the frame 29 is performed between the housing bracket 90 and the printing device 11, the frame 29 can be made difficult to be caught by the printing device 11 and the shelf section 91.

[0055] Further, the printing device 11 is provided with the exchange unit 40, and is provided with a first tapered section 19a that is provided at a passing port 19 through which the frame 29 passes when the frame 29 is moved between the printing device 11 and the housing bracket 90, and that guides the frame 29 to a fixed position where the frame 29 is fixed when the frame 29 is subjected to the printing process by the printing section 22. Therefore, in the printing device 11, when the frame 29 is carried in from the housing bracket 90 to the printing device 11, the frame 29 can be made difficult to be caught by the printing device 11.

[0056] Further, the housing bracket 90 is a housing bracket that can be accommodated in the exchange unit 40 provided in the printing device 11 that is provided with a printing section 22 that performs a printing process of a viscous fluid on an object to be processed using a screen mask M. Further, the housing bracket 90 is provided with a bracket main body 90a that is formed with an opening section 92 through which a frame that supports a replaceable section including the screen mask M passes when the frame is exchanged between the housing bracket 90 and the printing device 11, a plurality of shelf sections 91 that are provided inside the bracket main body 90a and that house the frame 29, and a second tapered section 91b that is formed at the opening section 92 and that is narrowed in a manner that a passage 91a guides the frame 29 to a housing position of the shelf section 91. Therefore, in the printing device 11, when the frame 29 is carried out to the housing bracket 90, the frame 29 can be made difficult to be caught by the housing bracket 90.

[0057] Further, in the housing bracket 90, the second tapered section 91b can be formed at both the side face 91d side of the shelf section 91 and the front end 91c of the shelf section 91. Therefore, in the housing bracket 90, when the frame 29 is carried out from the printing device 11 to the housing bracket 90, the frame 29 can be made difficult to be caught by the housing bracket 90.

[0058] Furthermore, in the housing support 90, the replacement unit 40 consists of a pair of left-side units 41 and right-side units 61. The left-side unit 41 includes a second replacement section 44, which has: a delivery section 45 with a belt 47 that moves the frame 29 toward the printing device 11 or the housing support 90 side by friction of its surface 47a, and a second drive section 48 that drives the belt 47; and a moving section 46 that moves the delivery section 45 such that the surface 47a of the belt 47 of the delivery section 45 approaches or separates from the frame 29. Additionally, the support body 90a has an insertion space 95 for inserting the delivery section 45 of the second replacement section 44, and the shelf section 91 has a driven section 94 that actuates the frame 29 when the delivery section 45 comes into contact with it. The driven section 94 is, for example, spheroidally cast. Therefore, in the housing bracket 90, when the frame 29 is sent out via the delivery part 45 or pulled into the shelf part 91, the friction between the frame 29 and the shelf part 91 can be reduced. As a result, the frame 29 can be replaced smoothly in the housing bracket 90.

[0059] In addition, the printing system 12 includes a replacement unit 40, a printing device 11, and a storage bracket 90. Since the printing system 12 includes the replacement unit 40, the storage bracket 90 can be made more compact when the replaceable parts used in the printing device 11 are automatically replaced, similar to the replacement unit 40.

[0060] Furthermore, the storage device and printing system disclosed herein are not limited to the above-described embodiments; as long as they fall within the technical scope of this disclosure, they can be implemented in various ways.

[0061] For example, in the above embodiment, the second replacement part 44 is provided in the left unit 41, but it is not limited to this. The second replacement part 44 may also be provided in the right unit 61. In addition, in the replacement unit 40, the second replacement part 44 may be provided in both the left unit 41 and the right unit 61. In this case, the side driven part 94 of the receiving bracket 90 is omitted, and the insertion space 95 is provided on both sides. In this replacement unit 40, the frame 29 can be pulled in and sent out while simplifying the structure of the receiving bracket 90.

[0062] In the above embodiment, the replacement unit 40 includes a left unit 41 and a right unit 61. The main body of the replacement unit 40 is respectively arranged on the left and right sides of the housing of the printing apparatus 11. However, it is not particularly limited to this. As long as there is space to accommodate the receiving bracket 90, the replacement unit 40 can be made into an integral structure. In addition, the replacement unit 40 is arranged in front of the printing apparatus 11. However, it is not particularly limited to this. It can also be arranged in the rear or side.

[0063] In the above embodiment, the second exchange unit 44 is configured to transmit the power of the second driving unit 48 to the belt 47 via the plurality of pulleys 49, and in a state in which the surface 47a of the belt 47 is in abutment with the frame 29, the second driving unit 48 is driven to rotate the belt 47, thereby to send out the frame 29 from the housing stand 90 or to pull the frame 29 into the housing stand 90, but is not particularly limited thereto. For example, the second exchange unit 44 can also be configured by a rubber roller and a second driving unit 48 connected to the rubber roller to rotate the rubber roller, and in a state in which the surface of the rubber roller is in abutment with the frame 29, the second driving unit 48 is driven to rotate the rubber roller, thereby to send out the frame 29 from the housing stand 90 or to pull the frame 29 into the housing stand 90.

[0064] In the above embodiment, the first tapered portion 19a is provided in the opening 19, but can be omitted, and the guide 26a can be provided as a tapered portion. That is, the guide 26a can have a tapered surface. In the printing device 11, the movement of the frame 29 can be smoothly performed.

Further, in the printing device 11 having the first tapered portion 19a, the movement of the frame 29 is smooth, which is preferable.

[0065] In the above embodiment, the second tapered portion 91b is provided in the opening 92 of the shelf portion 91 of the housing stand 90, but is not particularly limited thereto, and the second tapered portion 91b can be omitted. In the housing stand 90, the structure of the housing stand 90 can be simplified using the second exchange unit 44. Further, in the housing stand 90 having the second tapered portion 91b, the movement of the frame 29 is smooth, which is preferable.

[0066] In the above embodiment, the insertion space 95 is provided as a groove-shaped space at a position of each shelf portion 91 on the side of the stand body 90a opposite to the left unit 41, but is not particularly limited thereto. For example, the insertion space 95 can be a space of a shape in which two or more groove-shaped insertion spaces 95 are communicated in the vertical direction.

[0067] In the above embodiment, the printing device 11 outputs the pull-in instruction, and the exchange unit 40 outputs the send-out instruction, but is not particularly limited thereto, and one or more of these instructions can be omitted. For example, by providing a detection sensor that detects the frame 29 in the printing device 11 or providing a detection sensor that detects the frame 29 in the exchange unit 40, these instructions can be omitted. Further, in the printing system 12, the detection sensor is not provided, and the structure can be simplified.

[0068] In the above embodiment, in the printing system 12, the exchange unit 40 has the second exchange section 44 having the second driving section 48, the moving section 46, and the delivery section 45, but is not particularly limited thereto, and can be any as long as the frame 29 can be moved. Further, in the printing system 12, the first taper section 19a and the second taper section 91b are provided. In the printing system 12, because the tapers are provided, the movement of the frame 29 can be smoother.

[0069] In the above embodiment, the first receiving section 42 and the second receiving section 62 receive the housing bracket 90 by supporting the left and right end portions of the housing bracket 90 from the lower surface side, but are not particularly limited thereto, and can be any as long as the housing bracket 90 can be received. For example, the entire lower surface of the housing bracket 90 can be supported, or the housing bracket 90 can be supported from the side surface or the upper surface and received. Further, in the above embodiment, the exchange unit 40 receives the housing bracket 90 from the automated guided vehicle 18 by lifting the housing bracket 90 upward, and delivers the housing bracket 90 to the automated guided vehicle 18 by lowering the housing bracket 90 downward, but is not particularly limited thereto, and can be any as long as the housing bracket 90 can be received and delivered. Further, the automated guided vehicle 18 enters the lifting space 50 to perform the receiving and delivering of the housing bracket 90, but is not particularly limited thereto. For example, a conveyor or the like can be provided in any one of the placement section of the automated guided vehicle 18, the first receiving section 42, the second receiving section 62, and the like, and the receiving and delivering of the housing bracket 90 can be performed by stopping the automated guided vehicle 18 before the exchange unit 40.

[0070] In the above embodiment, the first exchange section 27 is configured as a lever mechanism having an abutting section provided to the print head 23, but is not particularly limited thereto, and can be configured as a separate mechanism provided to the print head 23. Further, in the above embodiment, the first exchange section 27 is configured as a lever mechanism that engages with the frame 29, but can be configured as a conveyor mechanism that places and moves the frame 29 including the replaceable component.

[0071] In the above embodiment, the replaceable component is described as the screen mask M, but is not particularly limited thereto, and can be any one or more of the cartridge 36 that houses the viscous fluid, the squeegee 25, the cleaning component 34 used for cleaning the screen mask M, and the support component 32 that supports the substrate S as a processing target, in addition to the screen mask M. Further, the processing target is described as the substrate S, but is not particularly limited thereto, and can be a three-dimensional object or the like. Further, the viscous fluid is described as the solder paste, but can be a conductive paste, an adhesive, or the like.

[0072] In the above-described embodiments, the printing system 12 including the printing device 11, the exchange unit 40, and the housing stand 90 is described, but the present disclosure can be configured to include one or more of the printing device 11, the exchange unit 40, and the housing stand 90.

[0073] The present disclosure can also be configured as follows.

[0074] The housing stand of the present disclosure can be housed in an exchange unit provided to a printing device having a printing section that performs printing processing of a treatment target object with an adhesive fluid using a screen mask, the housing stand including: a main body section in which an opening section through which a frame that supports a replaceable section including the screen mask passes when the frame is exchanged between the housing stand and the printing device is formed; a plurality of shelf sections provided inside the main body section to house the frame; and a tapered section formed in the opening section and narrowed in a manner that guides the frame toward a housing position of the shelf section.

[0075] The housing stand includes a tapered section formed in the opening section and narrowed in a manner that guides the frame toward a housing position of the shelf section. Therefore, when the frame is carried out of the printing device toward the housing stand, the frame can be difficult to get caught in the housing stand.
