Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the above-described printing apparatus is provided with a plurality of storage shelves for placing the screen mask, but each storage shelf is provided with a belt conveyor for inserting and removing the screen mask, and the configuration is complicated.

[0005] The present disclosure has been made in view of such problems, and a main object thereof is to provide a storage device and a printing system capable of simplifying the configuration when loading and unloading and stocking an object to be exchanged used in a printing apparatus.

Means for Solving the Problems

[0006] The storage device and the printing system disclosed in this specification have adopted the following means in order to achieve the above main object.

[0007] The storage device of the present disclosure is A storage device used in a printing apparatus having a printing unit that performs printing processing of a viscous fluid on a printing target using an object to be exchanged including a screen mask, There is a delivery stage for carrying in and out the object to be exchanged between the printing unit, a storage unit that accommodates a plurality of placement units on which the object to be exchanged is placed and stores the object to be exchanged, A placement unit moving unit that moves any one of the placement units to the delivery stage, An object moving unit that is disposed on the delivery stage, moves between a retracted position where it passes through the placement unit and a contact position where it contacts the object to be exchanged on the placement unit, and contacts the object to be exchanged at the contact position to move the object to be exchanged in the carry-in / carry-out direction, and is provided with the above.

[0008] In this storage device, the object moving unit is disposed on a delivery stage for carrying in and out the object to be exchanged between the printing unit, retracts to the retracted position, moves any one of the placement units to the delivery stage, moves to the contact position, contacts the object to be exchanged, and moves this object to be exchanged in the carry-in / carry-out direction. Thus, in this storage device, since it is not necessary to provide an object moving unit for all of the placement units, the configuration can be further simplified when carrying in and out and stocking the object to be exchanged used in the printing apparatus. Here, examples of the "object to be exchanged" include, in addition to a screen mask, a cartridge that stores a viscous fluid, a squeegee, a cleaning member used for cleaning the screen mask, and a support member for fixing the printing target. Examples of the "printing target" include, for example, a substrate on which components are mounted and a three-dimensional object. Examples of the "viscous fluid" include solder paste, conductive paste, adhesive, and the like. In this storage device, the object moving unit may be disposed only on the delivery stage. Also, the "delivery stage" may be only one stage or may have a plurality of stages, but one stage is preferable because the configuration can be further simplified. In this storage device, the configuration can be most simplified. Also, in this storage device, the placement unit moving unit may move the placement unit in the vertical direction, and the object moving unit may move the object to be exchanged in the horizontal direction as the carry-in / carry-out direction.

Embodiments for Carrying Out the Invention

[0010] This embodiment will be described below with reference to the drawings. FIG. 1 is a schematic explanatory diagram showing an example of an implementation system 10 including a printing device 11 which is an example of the present disclosure. FIG. 2 is a schematic explanatory diagram of the storage device 40 and the printing device 11. FIG. 3 is an explanatory diagram of the object moving unit 44 and the placement unit 50, where FIG. 3A is a plan view and FIG. 3B is a front view. FIG. 4 is a block diagram showing the electrical connection relationship of the implementation system 10. The implementation system 10 is, for example, a system for mounting components on a substrate S. This implementation system 10 includes a printing system 12 having a printing device 11 and a storage device 40, a mounting device 13, an automated guided vehicle 14, a management computer (PC) 18, and a storage device 40. The implementation system 10 is configured as a mounting line in which a plurality of mounting devices 13 for mounting components on the substrate S are arranged on the downstream side of the printing device 11. In the present embodiment, the left-right direction (X-axis), the front-back direction (Y-axis), and the up-down direction (Z-axis) are as shown in FIGS. 1 to 3 and FIGS. 5 to 10.

[0011] The mounting device 13 is a device for mounting components on a substrate S on which a viscous fluid such as solder paste has been printed by the printing device 11. The automated guided vehicle 14 moves between a storage vault for storing members related to the mounting process and the mounting line, and automatically transports members such as a screen mask M. A storage device 40 is connected to the printing device 11, and the automated guided vehicle 14 temporarily stores the transported members in the storage device 40. The management PC 18 is a device for managing information on each device of the implementation system 10. This management PC 18 manages the progress status of each device on the mounting line, the members being transported by the automated guided vehicle 14, the current position, and the like. Each device of the implementation system 10 exchanges information with the management PC 18 and acquires information such as the progress status of other devices.

[0012] As shown in FIGS. 1 to 4, the printing apparatus 11 is an apparatus that applies (prints) solder as a viscous fluid to a substrate S as a printing target below through a pattern hole formed in a screen mask M by pushing the solder on the screen mask M into the pattern hole using a squeegee 25. Examples of the "printing target" include a substrate S on which components are mounted, a three-dimensional object, and the like. Examples of the "viscous fluid" include solder paste, conductive paste, adhesive, and the like. Here, the substrate S and solder will be described below as an example. The printing apparatus 11 includes a control unit 21 (see FIG. 4), a printing unit 22, a mask working unit 26, a substrate processing unit 30, a cleaning unit 32, and a supply unit 34. The control unit 21 is configured as a microprocessor centered on a CPU and controls the entire printing apparatus 11.

[0013] The printing unit 22 is disposed at the upper stage of the printing apparatus 11 and is a unit that performs printing processing of a viscous fluid onto the substrate S using the screen mask M. As shown in FIGS. 1 and 4, the printing unit 22 includes a printing head 23, a printing moving unit 24, a squeegee lifting unit, and a squeegee 25. The printing moving unit 24 moves the printing head 23 in a predetermined printing direction (here, the front-rear direction), and includes a guide formed in the front-rear direction, a slider that moves along the guide, and a motor that drives the slider. The squeegee 25 is disposed on the lower surface side of the printing head 23 and is lifted and lowered by the squeegee lifting unit. The printing unit 22 has two squeegees 25 respectively used in the front-rear direction. The mask working unit 26 is disposed between the printing unit 22 and the substrate processing unit 30 in the vertical direction as shown in FIG. 2 and is a unit that fixedly holds the screen mask M. As shown in FIG. 4, the mask working unit 26 includes a mask moving unit 27 and a mask fixing unit 28. The mask moving unit 27 is a transfer rod provided on the printing head 23 and is lowered to a position where it abuts against the screen mask M by an air cylinder (not shown). The mask fixing unit 28 positions the screen mask M and supports and fixes it in a horizontal posture. The screen mask M is pushed by the mask moving unit 27 and moves back and forth along the guide of the mask working unit 26 and is fixed by the mask fixing unit 28. The substrate processing unit 30 is disposed below the mask working unit 26 as shown in FIG. 2 and is a unit that carries in the substrate S, positions and supports the carried-in substrate S, and brings it into contact with and separates from the screen mask M. The substrate processing unit 30 includes a substrate transfer unit 31 that transfers the substrate S in the left-right direction, a substrate support member that supports the substrate S from below, and a substrate lifting unit that lifts and lowers the entire substrate processing unit 30 and the substrate support member. The cleaning unit 32 is disposed between the mask working unit 26 and the substrate processing unit 30 in the vertical direction as shown in FIG. 2 and is a unit that performs a cleaning process for cleaning the back surface of the screen mask M. The cleaning unit 32 has a cleaning member 33, and the screen mask M is cleaned with this cleaning member 33. The supply unit 34 is a unit that supplies the solder accommodated in the cartridge 35 onto the screen mask M. The supply unit 34 is disposed in front of the printing head 23. The supply unit 34 applies pressure to the cartridge 35 to discharge the solder from the cartridge 35.The cleaning member 33 and the cartridge 35 are consumables and are replaced as necessary.

[0014] The storage device 40 is disposed in front of the printing device 11. The storage device 40 stores objects to be replaced used in the printing device 11 including the screen mask M and performs the loading and unloading of the objects to be replaced between the printing device 11 and the unmanned transport vehicle 14. Here, the "objects to be replaced" include, for example, in addition to the screen mask M, a cartridge 35 that stores a viscous fluid, a squeegee 25, a cleaning member 33 used for cleaning the screen mask M, and a support member (substrate support member) that fixes the object to be printed. Here, the screen mask M will be mainly described.

[0015] This storage device 40 includes a control unit 41, a storage unit 42, a placement unit moving unit 43, an object moving unit 44, a loading / unloading unit 47, a placement unit 50, and a door unit 53. The placement unit 50 is a shelf on which the screen mask M is placed. As shown in FIG. 3, the placement unit 50 has a support roller 51 and a plate 52. The support roller 51 supports the screen mask M without being connected to a drive unit and is disposed at two locations near the ends of a support shaft rotatably supported by the side wall. A plurality of (six) support rollers 51 are disposed at a plurality of locations on this placement unit 50. The support roller 51 is provided in a region outside the printing region of the screen mask M so as to support at least the end region E (frame portion) of the screen mask M (see FIG. 3B). The plate 52 is a plate-like member disposed below the printing region of the screen mask M placed on the support roller 51. This plate 52 is removably fixed to the housing of the placement unit 50. In the storage device 40, a plurality (for example, five) of these placement units 50 are accommodated in the storage unit 42.

[0016] The control unit 41 is configured as a microprocessor centered on a CPU, and controls the entire storage device 40, such as driving each drive unit (motor or air cylinder). The storage unit 42 is formed inside the housing of the storage device 40, has a delivery stage 58 for carrying in and out the screen mask M to and from the printing unit 22, houses a plurality of placement units 50, and stores the screen mask M. An opening 16 through which the screen mask M and the like pass is formed in the delivery stage 58 on the printing device 11 side of the storage unit 42. Further, a loading / unloading port 17 through which the screen mask M and the like pass is formed in the delivery stage 58 on the side of the automated guided vehicle 14 in the storage unit 42 (see FIGS. 1 and 2). The placement unit moving unit 43 performs a process of moving any one of the placement units 50 to the delivery stage 58. As shown in FIG. 2, the placement unit moving unit 43 has a plurality of support parts that support the placement unit 50 at predetermined intervals, and raises and lowers the placement unit 50 in the vertical direction (Z-axis direction) by a linear drive unit formed in the vertical direction.

[0017] The object moving unit 44 is a unit that abuts against the screen mask M and moves it in the loading / unloading direction (Y-axis direction, front-rear direction). As shown in FIG. 3, the object moving unit 44 is disposed on the delivery stage 58 and moves between a retracted position (dotted line in the figure) that allows the placement unit 50 to pass through and a contact position (solid line in the figure) that abuts against the screen mask M on the placement unit 50. In FIG. 3, the object moving unit 44 at the left contact position is omitted. When the placement unit 50 moves up and down, the object moving unit 44 moves to the retracted position to avoid contact with the placement unit 50. The object moving unit 44 includes a clamping member 45, a conveying roller 46, a driven roller, a retraction driving unit 56, and a conveying driving unit 57. The object moving unit 44 has at least one pair of clamping members 45 and conveying rollers 46 on the left and right. Only one pair of the object moving unit 44 is disposed on the delivery stage 58. The clamping member 45 is a member that moves between the retracted position and the contact position and clamps the end of the screen mask M. The clamping member 45 is disposed on the side surface side of the screen mask M. The clamping member 45 is a belt that is stretched between the conveying roller 46 and the driven roller and is driven by the conveying roller 46 to directly abut against the screen mask M. That is, the object moving unit 44 is configured as a pair of left and right belt conveyors. The contact surface where the belt abuts against the screen mask M is disposed along the vertical direction. This belt abuts against the side surface of the frame on the outer periphery of the screen mask M. The conveying roller 46 moves between the retracted position and the contact position together with the clamping member 45, and moves the screen mask M in the loading / unloading direction by sending the clamping member 45. Although omitted in the figure, there may be one or more support rollers that support the clamping member 45 between the conveying roller 46 and the driven roller. The retraction driving unit 56 moves the clamping member 45 and the conveying roller 46 between the retracted position and the contact position. The retraction driving unit 56 is connected to the central axis of the conveying roller 46, and moves the clamping member 45 in the horizontal direction (X-axis direction) perpendicular to the loading / unloading direction via this central axis. The retraction driving unit 56 is fixed to the housing of the storage device 40 and supports the clamping member 45 and the conveying roller 46 so as to suspend them downward (see FIGS. 2 and 3B). The retraction driving unit 56 may be an air cylinder or a linear motor.The conveying drive unit 57 is a motor that rotationally drives the conveying roller 46 and is disposed above the conveying roller 46. The retracting drive unit 56 and the conveying drive unit 57 are fixed at positions outside the lifting area of the mounting unit 50 so as not to obstruct the lifting of the mounting unit 50 (see Fig. 3A).

[0018] The loading / unloading unit 47 is a unit that loads and unloads exchange objects such as the screen mask M with the automated guided vehicle 14. As shown in Fig. 2, the loading / unloading unit 47 is stored in the storage unit 42 and disposed on the delivery stage 58. By protruding from the storage unit 42 to the outside, the loading / unloading unit 47 performs the process of pulling the screen mask M into the storage unit 42 or sending the screen mask M out of the storage unit 42. The automated guided vehicle 14 may not be equipped with a device for sending the screen mask M to the outside. In the storage device 40, the loading / unloading unit 47 protruding to the outside exchanges the screen mask M with the automated guided vehicle 14. The loading / unloading unit 47 includes a gripping member 48, a loading / unloading roller 49, a movement drive unit, and a rotation drive unit. The gripping member 48 is a member for gripping the end of the exchange object disposed outside the storage device 40. The loading / unloading roller 49 moves together with the gripping member 48 and directly contacts the screen mask M to move it in the loading / unloading direction. The loading / unloading roller 49 is disposed on the tip side of the gripping member 48. The movement drive unit is a motor that rotationally drives the loading / unloading roller 49 and is disposed at the tip of the gripping member 48 together with the loading / unloading roller 49. The rotation drive unit is a rotary actuator that rotates the gripping member 48 between the gripping position and the release position. This rotation drive unit is connected to the rotation axis of the gripping member 48. The loading / unloading unit 47 has at least one pair of the gripping member 48, the loading / unloading roller 49, the movement drive unit, and the rotation drive unit, and grips and moves the side surfaces of the screen mask M from both sides. The gripping member 48 and the rotation drive unit are supported and fixed from the lower side of the delivery stage 58 to avoid interference with the object moving unit 44.

[0019] The door part 53 is a shutter unit that restricts the movement of the screen mask M to the outside. The door part 53 is disposed at two locations, namely, near the opening 16 (see FIG. 1) and near the loading / unloading port 17. Here, the illustration of the door part 53 disposed at the loading / unloading port 17 is omitted. As shown in FIGS. 1 and 4, the door part 53 has a shielding plate 54 and an opening / closing drive part 55. The shielding plate 54 moves between a restricting position (solid line in FIG. 1) that restricts the movement of the screen mask M on the delivery stage 58 in the loading / unloading direction and an open position (dotted line in FIG. 1) that enables the movement of the screen mask M in the loading / unloading direction. The shielding plate 54 of this door part 53 moves in a direction (vertical direction) perpendicular to the loading / unloading direction in which the screen mask M moves. The opening / closing drive part 55 is an actuator that moves the shielding plate 54 between the restricting position and the open position. The placement part 50 has support rollers 51 that rotate freely, facilitating the smooth movement of the screen mask M. The door part 53 is fixed at the restricting position except when loading / unloading the screen mask M, restricting the unintended movement of the screen mask M to the outside.

[0020] Next, the operation of the storage device 40 configured in this way will be described. First, the process of loading the screen mask M as an object to be exchanged from the automated guided vehicle 14 into the storage device 40 will be described. FIG. 5 is an explanatory diagram of the process of loading the screen mask M into the storage device 40. FIG. 5A shows the figure when the loading / unloading unit 47 is in the release position, FIG. 5B shows the figure when the loading / unloading unit 47 grips the screen mask M, and FIG. 5C shows the figure of loading the screen mask M. It is assumed that the automated guided vehicle 14 places the screen mask M at the height of the delivery stage 58. First, the control unit 41 receives a loading command for the screen mask M conveyed by the automated guided vehicle 14 from the management PC 18. The control unit 41 moves the shielding plate 54 of the door unit 53 to the open position to open the loading / unloading port 17 and fixes the loading / unloading unit 47 at the release position (FIG. 5A). The automated guided vehicle 14 stops in front of the storage device 40. Next, the control unit 41 drives the rotation drive unit to rotate the gripping member 48 and move it to the gripping position, and the gripping member 48 grips the screen mask M (FIG. 5B). Subsequently, the control unit 41 drives the movement drive unit to rotate the loading / unloading roller 49 in contact with the side surface of the screen mask M and move the screen mask M in the loading / unloading direction (FIG. 5C). When the screen mask M enters the inside of the storage unit 42, the control unit 41 causes the clamping member 45 to contact the side surface of the screen mask M by the retraction drive unit 56, and drives the conveying roller 46 by the conveying drive unit 57 to move the screen mask M to the central region of the placement unit 50. Then, the control unit 41 moves the shielding plate 54 of the door unit 53 to the restriction position to restrict the movement of the screen mask M to the outside. In this way, the storage device 40 can store the screen mask M in the storage unit 42 by using the loading / unloading unit 47.

[0021] Next, the process of carrying the screen mask M from the storage device 40 to the printing device 11 will be described. FIG. 6 is an explanatory diagram of the process of sending the screen mask M to the printing device 11. FIG. 6A is a diagram of the preparation state, FIG. 6B is a diagram of the movement by the object moving unit 44, and FIG. 6C is a diagram of the loading by the mask moving unit 27. The delivery stage 58 of the placement unit 50 and the mask working unit 26 are at the same height, and the screen mask M is moved horizontally. First, the control unit 41 and the control unit 21 receive a command to carry the screen mask M into the printing device 11 from the management PC 18. The control unit 41 moves the shielding plate 54 of the door unit 53 to the open position to open the opening 16. Also, the control unit 41 moves the clamping member 45 to the contact position by the retraction drive unit 56, and clamps the side surface of the screen mask M with the clamping member 45 (FIG. 6A). Next, the control unit 41 drives the conveyance drive unit 57, rotates the conveyance roller 46, and moves the screen mask M in the carry-in / out direction with the clamping member 45 (FIG. 6B). The control unit 21 moves the print head 23 to a position where the mask moving unit 27 can move the screen mask M. Also, the control unit 21 lowers the conveyance rod of the mask moving unit 27. Subsequently, when the screen mask M is carried out of the storage unit 42, the control unit 41 moves the clamping member 45 to the retracted position by the retraction drive unit 56, and moves the shielding plate 54 to the restricted position by the opening / closing drive unit 55. Also, the control unit 21 brings the conveyance rod of the mask moving unit 27 into contact with the frame of the screen mask M, and moves the screen mask M together with the print head 23 (FIG. 6C). In this way, the storage device 40 can send the screen mask M to the printing device 11 using the object moving unit 44.

[0022] Next, the process of carrying the screen mask M from the printing device 11 to the storage device 40 will be described. FIG. 7 is an explanatory diagram of the process of carrying the screen mask M out of the printing device 11, where FIG. 7A is a diagram of the preparation state, FIG. 7B is a diagram of the movement by the mask moving unit 27, and FIG. 7C is a diagram of the loading by the object moving unit 44. First, the control unit 41 and the control unit 21 receive a command to carry the screen mask M to the storage device 40 from the management PC 18. The control unit 41 moves the shielding plate 54 of the door portion 53 to the open position to open the opening 16 (FIG. 7A). Also, the control unit 21 moves the print head 23 to the position where the screen mask M is to be moved, lowers the transfer rod, and brings it into contact with the frame of the screen mask M. Subsequently, the control unit 21 moves the print head 23 so as to push the frame of the screen mask M, and moves the screen mask M in the carry-in / carry-out direction (FIG. 7B). Next, the control unit 41 moves the clamping member 45 to the contact position by the retraction drive unit 56, and clamps the side surface of the screen mask M with the clamping member 45. Next, the control unit 41 drives the conveyance drive unit 57, rotates the conveyance roller 46, and moves the screen mask M in the carry-in / carry-out direction by the clamping member 45. Subsequently, when the screen mask M is accommodated inside the storage unit 42, the control unit 41 moves the clamping member 45 to the retracted position by the retraction drive unit 56, and moves the shielding plate 54 to the restricting position by the opening / closing drive unit 55. Also, the control unit 41 may move the placement unit 50 on which the used screen mask M is placed to a stage different from the delivery stage 58 by the placement unit moving unit 43 (FIG. 7C). In this way, the storage device 40 can collect the screen mask M using the object moving unit 44.

[0023] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The storage unit 42 of this embodiment corresponds to the storage unit, the placement unit moving unit 43 corresponds to the placement unit moving unit, the object moving unit 44 corresponds to the object moving unit, the carry-in / carry-out unit 47 corresponds to the carry-in / carry-out unit, and the door portion 53 corresponds to the door portion.

[0024] In the storage device 40 of the present embodiment described above, the object moving unit 44 is disposed at the delivery stage 58 that transfers the screen mask M as the object to be exchanged to and from between the printing unit 22. The object moving unit 44 moves to either the storage position and is placed on the placement unit 50 to the delivery stage 58, and moves to the contact position to contact the object to be exchanged and move it in the transfer direction. In this way, in this storage device 40, since it is not necessary to provide the object moving unit 44 for all of the placement units 50, the configuration can be further simplified when transferring and storing the object to be exchanged used in the printing device 11. Further, the object moving unit 44 has at least one pair of a clamping member 45 that moves between the storage position and the contact position and clamps the end of the object to be exchanged, and a conveying roller 46 that moves together with the clamping member 45 and moves the object to be exchanged in the transfer direction. In this storage device 40, the object to be exchanged can be clamped by the clamping member 45 and moved in the transfer direction by the conveying roller 46. Further, the clamping member 45 is a belt that is stretched over the conveying roller 46 and is driven by the conveying roller 46 to contact the object to be exchanged. In this storage device 40, the object to be exchanged can be more reliably clamped and conveyed using a belt conveyor. Furthermore, since the clamping member 45 is disposed on the side surface side of the object to be exchanged, the object to be exchanged can be moved in the transfer direction by clamping it from the side surface of the object to be exchanged. Also, in this storage device 40, since the object moving unit 44 retracts to the side surface side, that is, in the horizontal direction, it is difficult to interfere with the movement of the placement unit 50 when the placement unit 50 moves in the vertical direction.

[0025] In addition, the placement section 50 is provided with a plurality of support rollers 51 that at least support the end portion of the object to be exchanged. In this storage device 40, since it is supported by the support rollers 51, the movement of the object to be exchanged can be made smoother. Also, since the placement section 50 is provided with support rollers 51 that do not have a drive section, the configuration can be made simpler. Furthermore, the support rollers 51 of the placement section 50 are provided in an area outside the printing area of the screen mask M (the area of the frame). The screen mask M may have a viscous fluid adhering to its back surface. Since this support roller 51 is not arranged in the printing area, soiling of the support roller 51 and the like can be suppressed. And also, the placement section 50 includes a removable plate 52 below the printing area of the placed screen mask M. In this storage device 40, even if the viscous fluid drops from the screen mask M, it can be received by the plate 52, so the plate 52 can be removed and easily cleaned.

[0026] In addition, this storage device 40 includes a door section 53 that moves between a regulation position that regulates the movement of the object to be exchanged in the loading / unloading direction of the delivery stage 58 and an open position that enables the movement of the object to be exchanged in the loading / unloading direction. In this storage device 40, the door section 53 can prevent the object to be exchanged from inadvertently going outside the device. This door section 53 moves in a direction orthogonal to the direction in which the object moving section 44 moves. For example, assuming that the object moving section 44 moves in the horizontal direction, the door section 53 moves in the vertical direction. In this storage device 40, it is preferable that the movement of the object moving section 44 and the movement of the door section 53 do not easily interfere with each other.

[0027] In addition, the storage device 40 is stored in the storage section 42 and disposed on the delivery stage 58. By protruding from the storage section 42 to the outside, the storage device 40 is provided with a loading / unloading section 47 that draws the object to be exchanged into the storage section 42 or sends the object to be exchanged out of the storage section 42. In this storage device 40, the loading / unloading section 47 protruding to the outside makes it easy to draw the object to be exchanged into the storage section 42 and to send it out of the storage section 42. Further, the loading / unloading section 47 has at least one pair of a gripping member 48 for gripping an end portion of the object to be exchanged disposed outside the storage device 40, and a loading / unloading roller 49 that moves together with the gripping member 48 and moves the object to be exchanged in the loading / unloading direction. In this storage device 40, the object to be exchanged can be gripped by the gripping member 48 and drawn into the storage section 42 or sent out of the storage section 42 by the loading / unloading roller 49.

[0028] In addition, the printing system 12 includes the above-described storage device 40 and a printing device including a printing section 22 that performs printing processing of a viscous fluid on a substrate S as a printing target using the object to be exchanged sent out from the storage device 40. In this printing system 12, similar to the above-described storage device 40, the configuration can be further simplified when loading / unloading and stocking the object to be exchanged used in the printing device 11.

[0029] Note that the storage device and the printing system of the present disclosure are not limited to the above-described embodiments at all, and it goes without saying that they can be implemented in various modes as long as they belong to the technical scope of the present disclosure.

[0030] For example, in the above-described embodiment, the storage device 40 has been described as having only one delivery stage 58, but it is not particularly limited thereto, and it may have two or more stages. At this time, if the number of delivery stages 58 is smaller than that of the placement sections 50, the object moving section 44 can be reduced, and the configuration can be further simplified. Note that the object moving section 44 only needs to be disposed on the delivery stage 58, and may exist on other stages if the configuration is to be simplified.

[0031] In the above-described embodiment, the object moving unit 44, which is a belt conveyor having the clamping member 45 as a belt and the conveying roller 46 for driving the belt, has been described. However, it is not particularly limited thereto. FIG. 8 is an explanatory diagram showing an example of another object moving unit 44B. In this object moving unit 44B, the clamping member 45B is a support member that supports the conveying roller 46B, and the conveying roller 46B is disposed on the clamping member 45B and directly contacts the object to be exchanged to move this object to be exchanged in the loading / unloading direction. In this storage device 40B, the conveying roller 46B is moved between the retracted position and the contact position by the clamping member 45B as a support member, and the conveying roller 46B can directly contact the object to be exchanged and move it.

[0032] Alternatively, the object moving unit that moves the object to be exchanged is not limited to having the clamping member 45 and the conveying roller 46. FIG. 9 is an explanatory diagram showing an example of another object moving unit 44C. This object moving unit 44C has at least one pair of a clamping member 45C that moves between a retracted position and a contact position and clamps the end of the object to be exchanged, and a linear drive unit 46C that moves the object to be exchanged in the loading / unloading direction together with the clamping member 45C. In this storage device 40C, the object to be exchanged can be clamped by the clamping member 45C and moved in the loading / unloading direction by the linear drive unit 46C. The linear drive unit 46C may be, for example, an air cylinder or a linear motor. Further, the linear drive unit 46C may be configured to be able to move the clamping member 45C supported by the extending support member to the outside of the storage unit 42 (see the two-dot chain line in FIG. 9). In this storage device 40C, the object moving unit 44C can also serve as the loading / unloading unit 47. In FIG. 9, only one pair of the clamping members 45C is provided, but two or more pairs may be provided.

[0033] In the above-described embodiment, the storage device 40 is provided with the carry-in / carry-out unit 47 including the gripping member 48 and the carry-in / carry-out roller 49. However, as long as it protrudes to the outside to exchange objects, it is not particularly limited to this. FIG. 10 is an explanatory diagram showing an example of another carry-in / carry-out unit 47B. This carry-in / carry-out unit 47B includes a hook member 48B that is supported by the shaft 60 and hooks the end of the object to be exchanged disposed outside the storage device 40 and moves it in the carry-in / carry-out direction, a guide member 59 that guides the hook member 48B between the protruding position outside the storage device 40 and the retracted position inside the storage device 40, and a drive unit 49B that moves the hook member 48B along the guide of the guide member 59. The shaft 60 is inserted into the guide hole of the guide member 59 and moves along the guide hole. A regulating plate for guiding the shaft 60 in one direction is provided in the guide hole. The regulating plate opens the guide hole when pushed from below. This regulating plate moves the shaft 60 in the front-rear direction from the retracted position to the hooked position, and when the shaft 60 enters from below, it opens to enable the shaft 60 to move to the retracted position. In this carry-in / carry-out unit 47B, the hook member 48B hooks the object to be exchanged, and by moving the hook member 48B along the guide of the guide member 59 by the drive unit 49B, the object to be exchanged can be drawn into the storage unit 42 or sent out from the storage unit 42. Note that when the placement unit 50 moves up and down, this carry-in / carry-out unit 47B is bounced up from the horizontal state (FIG. 10) to the vertical state so as not to interfere with the movement of the placement unit 50.

[0034] Alternatively, the carry-in / carry-out unit for drawing in and sending out the object to be exchanged is not limited to the one including the gripping member 48 and the carry-in / carry-out roller 49. For example, the carry-in / carry-out unit may have at least one pair of a gripping member for gripping the end of the object to be exchanged disposed outside the storage device 40 and a linear drive unit for moving the object to be exchanged in the carry-in / carry-out direction together with the gripping member (see FIG. 9). In this storage device, the object to be exchanged can be gripped by the gripping member and drawn into the storage unit or sent out from the storage unit by the linear drive unit. As shown in FIG. 9, the storage device 40 may share the object moving unit and the carry-in / carry-out unit, or these may be provided separately.

[0035] In the above-described embodiment, it is assumed that the printing apparatus 11 has the mask moving unit 27, but it may not have the mask moving unit 27. In this case, the storage device 40 may be provided with the loading / unloading unit 47 also on the printing apparatus 11 side. Further, although the automated guided vehicle 14 is not configured to draw in and send out the object to be exchanged, it may be provided with this configuration. In this case, the storage device 40 may omit the loading / unloading unit 47.

[0036] In the above-described embodiment, the object to be exchanged is the screen mask M, but it is not limited to this as long as it requires replacement. In addition to the screen mask M, it may be a cartridge 35 that stores a viscous fluid, a squeegee 25, a cleaning member 33 used for cleaning the screen mask M, a support member that fixes the object to be printed, and the like. Further, although the object to be printed is the substrate S, as long as it prints a viscous fluid, it is not particularly limited thereto, and it may be a three-dimensional object or the like. Further, although the viscous fluid is a solder paste, it may be a conductive paste, an adhesive, or the like.

[0037] In the above-described embodiment, the object moving unit 44 is disposed on the side surface side of the object to be exchanged and has been described as sandwiching and moving this side surface, but it is not particularly limited thereto. For example, the object moving unit 44 may sandwich and move the upper and lower surfaces of the object to be exchanged.

[0038] In the above-described embodiment, the support roller 51 is disposed only in the end region of the screen mask M and is a support shaft in other regions, but it is not particularly limited thereto, and the support roller may be formed over the entire support shaft. Further, although the placement unit 50 is provided with the support roller 51 and the plate 52, it is not particularly limited thereto, and any of these may be omitted. Even if the placement unit 50 has a placement surface, the screen mask M can be moved.

[0039] In the above-described embodiment, the door portion 53 in which the shielding plate 54 moves up and down is provided. However, the present invention is not particularly limited thereto, and the shielding plate 54 may move left and right. Further, the storage device 40 is provided with the door portion 53, but this may be omitted. When the door portion 53 is omitted, the storage device 40 may be provided with a locking mechanism for the support roller 51, or the support roller 51 itself may be omitted.
