[0011] Hereinafter, an embodiment in which the operation guidance system of the present disclosure is embodied will be described in detail with reference to the accompanying drawings. Figure 1 This shows the structure of the operation guidance system 10 of the present embodiment. As Figure 1 shown, the operation guidance system 10 includes a plurality of production lines 2, a plurality of production line management devices 3, a supervisory device 4, an automated guided vehicle 5, and a display terminal 6. The production line 2 includes, for example, a printing machine 11, a mounting device 13, a reflow oven 14, and a substrate appearance inspection machine 15 from the upstream side to the downstream side of the production line 2. The operation guidance system 10 is a system that transports the substrate S from the upstream to the downstream of the production line 2 and mounts components (electronic components, etc.) on the substrate S. In the following description, as Figure 1 shown, based on the direction (left and right, etc.) of observing the printing machine 11 from the front, the direction of transporting the substrate S is referred to as the left-right direction (X-axis direction), the direction parallel to the plane of the transported substrate S and orthogonal to the left-right direction is referred to as the front-back direction (Y-axis direction), and the direction orthogonal to both the left-right direction and the front-back direction is referred to as the up-down direction (Z-axis direction) for explanation.

[0012] The printing machine 11 is a screen printing machine, which is a device for printing a viscous fluid such as paste solder (hereinafter referred to as solder paste) onto a substrate S. In addition, the viscous fluid printed by the printing machine 11 is not limited to solder paste, and can also be a printing agent with the same properties, such as silver paste or adhesive. The mounting device 13 is a device for mounting components onto the substrate S printed with solder paste. The reflow oven 14 is a device for heating the substrate S on which components are mounted to melt and then solidify the solder paste. Thus, the components are mounted on the substrate S. The substrate appearance inspection machine 15 is a device for inspecting the mounting state of the substrate S on which components are mounted.

[0013] The production line management device 3 and the overall management device 4 are communicably connected to each device of the above-mentioned production line 2 via the network 7. The production line management device 3 is a device for managing the production line 2, and manages the progress status of each device of the production line 2. Each device of the production line 2 exchanges information with the production line management device 3 to obtain information such as the progress status of other devices. The overall management device 4 is a device for exchanging information with a plurality of production line management devices 3 and managing the production order in each production line 2. The details of the production line management device 3 and the overall management device 4 will be described later.

[0014] The automated guided vehicle 5 moves in the production facility provided with the operation guidance system 10, and performs the delivery of the components required in the production line 2 and the recovery of the components after use. The overall management device 4 manages the components carried by the automated guided vehicle 5, the current position of the automated guided vehicle 5, etc. In this embodiment, as an example of the components required in the production line 2, the case where the components required in the printing machine 11 (such as the screen mask M described later) are used will be described. In the production facility provided with the operation guidance system 10, a storage 8 for storing the components required in the production line 2 is provided. The automated guided vehicle 5 travels between the storage 8 and the production line 2 within the production facility, and automatically transports, for example, the screen mask M. The automated guided vehicle 5 is an example of the transport device of the present disclosure. In addition, the components of the present disclosure are not limited to the components required in the printing machine 11. In addition, the transport device of the present disclosure is not limited to a vehicle with wheels, and can also be a device that travels using a moving mechanism other than wheels such as a crawler. In addition, the transport device can also be a flying device such as a drone. That is, the moving method of the transport device is not limited to the method of traveling on the floor of the production facility.

[0015] The display terminal 6 is, for example, a personal computer, and is provided in the storage 8. The display terminal 6 is connected to the network 7 and displays the information obtained from the production line management device 3, the overall management device 4, etc. This information is, for example, the operation instruction information 73 described later (refer to Figure 7 、 Figure 9). The operation guidance system 10 causes the display terminal 6 to display operation instruction information 73, which instructs the automated guided vehicle 5 for automatic transportation to prepare for the recovery and delivery of components. The operator in the storage 8 confirms the operation instruction information 73 to implement the delivery and recovery of components. The operation guidance system 10 of this embodiment is a system for transporting components by both the automated guided vehicle 5 and humans. Details of the operation instruction information 73 will be described later. In addition, the device for displaying the operation instruction information 73 is not limited to a fixed device such as the above-mentioned personal computer, and may also be a portable device such as a laptop computer, a tablet terminal, or a smartphone.

[0016] In addition, Figure 1 The structure of the operation guidance system 10 shown is an example. For example, the operation guidance system 10 may have a structure with only one production line 2 and a production line management device 3, or may have a structure with multiple management devices 4. In addition, the operation guidance system 10 may also have devices other than the above-mentioned devices, such as a solder inspection machine for inspecting the application state of solder paste. In addition, in Figure 1 , multiple automated guided vehicles 5 are illustrated, but the operation guidance system 10 may have a structure with only one automated guided vehicle 5, or may have a structure with two or more automated guided vehicles. In addition, the operation guidance system 10 may also be a system in which all components are transported manually by humans without an automated guided vehicle 5. In this case, the operator may also transport the components manually while confirming the operation instruction information 73 described later.

[0017] (Automatic replacement system for the screen mask M) Next, a system for automatically replacing the screen mask M of the automatic replacement printing machine 11 will be described. As a system for automatically replacing the screen mask M, for example, the system of International Publication WO2019 / 225002 can be adopted. Therefore, in the following description, an overview of the system for automatic replacement will be described. The printing machine 11 is connected to a storage device 40. The automated guided vehicle 5 temporarily stores the transported components (in this embodiment, the screen mask M) in the storage device 40. As Figures 2 to 6 shown, the printing machine 11 uses a squeegee 25 to press the solder paste on the screen mask M into the pattern holes formed in the screen mask M, thereby applying (printing) the solder paste to the substrate S below through the pattern holes. In addition, Figure 2 The illustration of the reflow oven 14 and the substrate appearance inspection machine 15 is omitted.

[0018] The printing machine 11 includes a control unit 21 (refer to Figure 7 ), a printing unit 22, a mask operation unit 26, a substrate processing unit 30, a cleaning unit 32, a supply unit 34, a storage device 35 (refer to Figure 7). The control unit 21 is, for example, a microprocessor such as a CPU. The CPU executes a control program (not shown) stored in the storage device 35 to control the entire printing machine 11. The storage device 35 includes, for example, a RAM, a ROM, an HDD, etc. Task data JOB used when producing the substrate S is stored in the storage device 35 (refer to Figure 7 ). In addition, the storage device 35 is not limited to the above storage media, and may also be other storage media such as an SSD, a flash memory, or a storage media combining them. The storage device 35 may also be an external storage media such as a USB memory, or a storage media such as a CD-ROM, a DVD-RAM. The same applies to the other storage devices 62, 65, 79 described later.

[0019] The printing unit 22 is arranged in the upper part of the printing machine 11 and is a unit that prints solder paste on the substrate S using a screen mask M. As shown in the enlarged view of Figure 2 , the printing unit 22 includes a print head 23, a print moving unit 24, and a squeegee 25. The print moving unit 24 includes guides formed in the front-rear direction and moves the print head 23 in the front-rear direction. The squeegee 25 is a component that applies solder paste to the screen mask M and is arranged on the lower surface side of the print head 23. In the printing unit 22, a total of two squeegees 25 are provided respectively in the front-rear direction. The squeegee 25 needs to be replaced according to the size of the substrate S to be produced, etc. In addition, a mask moving unit 27 is provided on the lower surface side of the print head 23. The mask moving unit 27 is a rod for hooking the screen mask M to move the screen mask M and descends to a position in contact with the screen mask M by a cylinder (not shown).

[0020] As shown in Figure 3As shown, the mask operation unit 26 is arranged between the printing unit 22 and the substrate processing unit 30 in the vertical direction, positions the screen mask M and supports it in a horizontal posture. When the screen mask M is replaced, it is pulled by the mask moving unit 27 of the printing unit 22 and moves in the front-rear direction along the guide of the mask operation unit 26, and is fixed by the mask operation unit 26. The substrate processing unit 30 is arranged below the mask operation unit 26 and includes a substrate transfer unit 31, a clamping device 37, and a lifting table 38. The printing machine 11 has transfer ports formed on both side surfaces in the left-right direction. The substrate transfer unit 31 transfers the substrate S carried in from the transfer port on the upstream side (left side) to the right and discharges it from the transfer port on the downstream side. The substrate transfer unit 31 transfers the substrate S under the screen mask M provided inside the machine. The clamping device 37 is arranged on both sides of the substrate S in the front-rear direction. The lifting table 38 is lifted and lowered by a drive source (not shown) such as a motor or a cylinder with a support block 39 placed thereon. The lifting table 38 clamps and fixedly holds the substrate S between the support block 39 and the clamping device 37 in the vertical direction by raising the support block 39. The substrate processing unit 30 raises and lowers the substrate S positioned by the clamping device 37 through a lifting mechanism (not shown), brings the substrate S into contact with or separates the substrate S from under the screen mask M.

[0021] The support block 39 is a component for performing vacuum suction to correct the warp of the substrate S. A ventilation hose connected to a vacuum pump (not shown) is installed on the lifting table 38. The substrate processing unit 30 corrects the warp of the substrate S by evacuating the air chamber formed by the support block 39 using this vacuum pump. The support block 39 is formed according to the size of the substrate S. When there are pre-mounted components on the back surface of the substrate S, recesses corresponding to the positions of such components are formed. Therefore, the support block 39 needs to be replaced according to the type of substrate S to be produced. In addition, the components for clamping and correcting the warp of the substrate S are not limited to the support block 39, and can also be columnar components such as support pins.

[0022] The cleaning unit 32 is arranged between the mask operation unit 26 and the substrate processing unit 30 in the vertical direction and cleans the back surface of the screen mask M. The cleaning unit 32 has a cleaning component 33, and uses this cleaning component 33 to clean the back surface of the screen mask M. The cleaning component 33 is, for example, a cleaning paper. Since the cleaning component 33 is contaminated by cleaning, it needs to be replaced according to the specified number of uses, usage period, etc.

[0023] The supply unit 34 is a unit that supplies the solder paste stored in the cartridge 36 onto the screen mask M. The supply unit 34 is arranged in front of the print head 23, applies pressure to the cartridge 36 to discharge the solder paste from the cartridge 36. Since the solder paste stored in the cartridge 36 decreases due to repeated printing, the cartridge 36 needs to be replaced.

[0024] In addition, the box 36 is provided with a remaining amount detection sensor 36A (see Figure 3 ). As the remaining amount detection sensor 36A, for example, a liquid level sensor or a liquid level switch that detects the height of the liquid level in the container of the box 36 can be used. The printer 11 detects the remaining amount of solder paste in the box 36 based on the detection signal of the remaining amount detection sensor 36A. In addition, the method of detecting the remaining amount of solder paste is not limited to the method using the above-mentioned remaining amount detection sensor 36A. For example, a camera may be used to capture the solder paste (the solder roll after mixing) discharged from the box 36 onto the screen mask M, and the amount of solder paste used may be detected based on the captured image data, and the remaining amount may be calculated based on the amount used.

[0025] The screen mask M has different pattern holes depending on the printed pattern, so it is necessary to replace the screen mask M with a different printed pattern according to the type of substrate S to be produced. In addition, the screen mask M adheres to solder paste due to repeated use, so it needs to be cleaned and replaced with the screen mask M with the same printed pattern. In addition, as mentioned above, the scraper 25 and the support block 39 need to be replaced according to the type of substrate S. In addition, the box 36 and the cleaning component 33 need to be replaced according to consumption and contamination. In the operation guidance system 10 of this embodiment, the screen mask M can be automatically replaced by the unmanned guided vehicle 5. In addition, the remaining scraper 25, support block 39, box 36, and cleaning component 33 can be manually replaced by the operator. In addition, the unified management device 4 causes the display terminal 6 to display the operation instruction information 73 for the delivery of the replacement and the recycling of the used parts for these parts and instructs the operator. For the screen mask M that is the object of automatic replacement, the operator uses the unmanned guided vehicle 5 to implement the replacement. In addition, for other parts that need to be replaced manually, the operator prepares according to the indicated time, moves the prepared parts to the printing machine 11, and replaces them. Alternatively, the unmanned guided vehicle 5 can only transport the parts, and other operators located in front of the printing machine 11 receive the parts from the unmanned guided vehicle 5 and replace them manually. In this case, it is also possible to set a structure that can accommodate parts other than the screen mask M in the storage device 40, and transfer parts other than the screen mask M between the storage device 40 and the unmanned guided vehicle 5. In addition, the unmanned guided vehicle 5 can also be a structure that can transport more than two parts. It can also be a structure that can only transport one screen mask M or other parts. Therefore, the component replacement method (manual, automatic) and the component transportation method (unmanned guided vehicle 5, person) disclosed in the present invention can be appropriately changed.

[0026] In addition, the above-mentioned automatically replaced parts and manually replaced parts are examples. Figure 3As shown by the dashed arrow 28, it is also possible to configure the support block 39 to be replaceable between the printing machine 11 and the storage device 40, and the replacement can be automatically implemented. In this case, similar to the handling of the stencil mask M by the automated guided vehicle 5 described later, the support block 39 can be handled and replaced. In addition, the operation guidance system 10 can be configured to automatically replace all components to be replaced, or can be configured to manually replace all components. In addition, the components of the present disclosure are not limited to the above-mentioned stencil mask M, support block 39, squeegee 25, etc. For example, as a component to be replaced, it can also be a solder recovery plate for recovering the solder paste remaining on the stencil mask M. Such a solder recovery plate also needs to be changed according to the substrate type and regularly cleaned, so replacement is required.

[0027] The storage device 40 is arranged in front of the printing machine 11, stores the stencil mask M, and carries the stencil mask M in or out between it, the printing machine 11, and the automated guided vehicle 5. The storage device 40 includes a storage part 42, a carrier part moving part 43, a pair of object moving parts 44, a pair of loading / unloading parts 47, a carrier part 50, and a door part 53. The storage part 42 is formed inside the housing of the storage device 40, has a transfer layer 58 for transferring the stencil mask M between it and the printing machine 11, houses a plurality of (for example, 5) carrier parts 50, and stores the stencil mask M in each carrier part 50. In the storage part 42, an opening 16 for the stencil mask M to pass through is formed on the printing machine 11 side of the transfer layer 58. In addition, in the storage part 42, a loading / unloading port 17 for the stencil mask M to pass through is formed on the automated guided vehicle 5 side of the transfer layer 58. As Figure 3 shown, the carrier part moving part 43 has a support part that supports the carrier part 50 at a predetermined interval in the vertical direction (Z-axis direction), and uses a drive source (not shown) to lift and lower the carrier part 50 in the vertical direction to replace the carrier part 50 on the transfer layer 58.

[0028] The carrier part 50 is a shelf for placing the stencil mask M, and has a support roller 51 and a plate 52. The support roller 51 supports the stencil mask M from below and rotates according to the movement of the stencil mask M. The plate 52 is arranged below the support roller 51 and is detachably installed on the carrier part 50, and is a component for receiving the viscous fluid falling from the stencil mask M.

[0029] A pair of object moving parts 44 are in contact with the stencil mask M and move in the loading / unloading direction (Y-axis direction, front-rear direction). The pair of object moving parts 44 are arranged on the transfer layer 58 as Figure 3 shown, and are respectively arranged on both sides of the carrier part 50 on the transfer layer 58 in the left-right direction (X-axis direction) as Figure 4 shown. The pair of object moving parts 44 have the same structure, for example, a symmetric structure in the left-right direction. As Figure 3 and Figure 4As shown, each of a pair of object moving parts 44 has a plurality of carrying rollers 46, a belt 45 mounted on the carrying rollers 46, a pair of retracting drive parts 56, and a carrying drive part 57. The pair of retracting drive parts 56 are respectively provided, for example, at both ends in the front-rear direction at the placing part 50. The pair of retracting drive parts 56 are respectively connected to the carrying rollers 46, and drive a drive source (such as a cylinder) to move the belt 45 and the carrying rollers 46 in the left-right direction. Each of the pair of retracting drive parts 56 moves the belt 45 and the carrying rollers 46 to a contact position where the belt 45 contacts the screen mask M (refer to Figure 6 ), or a retracted position where it separates from the screen mask M (refer to Figure 4 ).

[0030] The carrying drive part 57 is a motor that rotates the carrying rollers 46. The pair of object moving parts 44 rotate the carrying rollers 46 at the contact position to rotate the belt 45, thereby moving the screen mask M in one direction of the loading / unloading direction. In addition, the pair of object moving parts 44 move the belt 45 and the carrying rollers 46 to the retracted position when the placing part 50 moves up and down. In addition, Figure 4 , Figure 5 shows a state where the pair of object moving parts 44 are arranged at the retracted position, Figure 6 shows a state where they are arranged at the gripping position.

[0031] A pair of loading / unloading parts 47 are arranged at the transfer layer 58, and are respectively provided on both sides and at the front ends of the placing parts 50 at the transfer layer 58 in the left-right direction. The pair of loading / unloading parts 47 load and unload the screen mask M between them and the automated guided vehicle 5. The pair of loading / unloading parts 47 protrude from the storage part 42 to the outside, thereby pulling the screen mask M from the automated guided vehicle 5 into the storage part 42, or sending the screen mask M from the storage part 42 to the automated guided vehicle 5. In addition, the automated guided vehicle 5 may also be provided with a loading / unloading part 47 for sending and pulling the screen mask M. In addition, both the storage device 40 and the automated guided vehicle 5 may be provided with a device for moving the screen mask M. In addition, the automated guided vehicle 5 may directly transfer the screen mask M with the printing machine 11. In this case, the printing machine 11 may not be provided with the storage device 40.

[0032] Each of the pair of loading / unloading parts 47 has the same structure, and includes a gripping member 48 and a loading / unloading roller 49. In addition, as Figure 4 , Figure 5 shown, the pair of loading / unloading parts 47 are configured to be rotatable, and rotate the gripping member 48 between a gripping position for gripping the screen mask M of the automated guided vehicle 5 (refer to Figure 5 ) and a release position where it separates from the screen mask M (refer to Figure 4 ). The loading / unloading roller 49 is provided at the front end of the gripping member 48, contacts the screen mask M, and rotates based on the drive of a motor (not shown), moving the screen mask M in the loading / unloading direction.

[0033] The door part 53 is a baffle unit that restricts the outward movement of the screen mask M. As Figure 2 shown, the door part 53 is arranged at two locations, near the opening part 16 and near the loading / unloading port 17. Additionally, in Figure 2 , the illustration of the door part 53 arranged at the loading / unloading port 17 is omitted. The door part 53 moves the shielding plate 54 in the vertical direction through an opening / closing drive part 55 (such as a motor). The door part 53 moves the shielding plate 54 between a restricted position ( Figure 2 solid line) that restricts the movement of the screen mask M of the transfer layer 58 in the loading / unloading direction and an open position ( Figure 2 dashed line) where the screen mask M of the transfer layer 58 can move in the loading / unloading direction.

[0034] Figures 4 to 6 Shows the operation of loading the screen mask M into the storage device 40. The automated guided vehicle 5, for example, moves to the height of the transfer layer 58 while carrying the screen mask M. As Figure 4 shown, the automated guided vehicle 5 is arranged in front of the storage device 40. For example, the overall control device 4 always manages the position of the automated guided vehicle 5. The method for detecting the position of the automated guided vehicle 5 is not particularly limited, and methods such as using GPS, detecting through sensors provided on the production line 2 and the automated guided vehicle 5, and detecting through image processing using a camera provided in the production facility can be used.

[0035] If the automated guided vehicle 5 is arranged in front of the printing machine 11 (storage device 40) for delivering and retrieving the screen mask M, the overall control device 4 instructs the storage device 40 to load and unload the screen mask M. For example, when the storage device 40 loads the screen mask M, it opens the shielding plate 54 of the loading / unloading port 17. The storage device 40 moves a pair of loading / unloading parts 47 from the release position (refer to Figure 4 ) to the gripping position (refer to Figure 5 ), and grips the screen mask M on the automated guided vehicle 5 using the pair of loading / unloading parts 47. The storage device 40 moves the belt 45 and the conveying roller 46 to the abutting position, and rotates the loading / unloading roller 49 and the conveying roller 46, thereby loading the screen mask M from the automated guided vehicle 5 to the placement part 50 of the transfer layer 58 (refer to Figure 6 ). The storage device 40 moves the shielding plate 54 of the loading / unloading port 17 to the restricted position to restrict the outward movement of the screen mask M. Additionally, when discharging the screen mask M, for example, by performing the opposite operation (such as reverse rotation) to the operation shown in Figures 4 to 6 , the screen mask M can be discharged from the storage device 40 to the automated guided vehicle 5.

[0036] In addition, the printing machine 11 and the storage device 40 can perform the loading of the screen mask M from the storage device 40 into the printing machine 11 and the discharging of the screen mask M from the printing machine 11 into the storage device 40. Without going into details, for example, similar to the handover of the screen mask M between the storage device 40 and the automated guided vehicle 5, the screen mask M is discharged into the printing machine 11 by opening the shielding plate 54 of the opening 16 and rotating the conveying roller 46. The printing machine 11 hooks the mask moving part 27 provided in the printing part 22 to the end of the screen mask M and pulls the printing part 22 backward, whereby the screen mask M is arranged into the printing machine 11 (mask operation part 26) by the mask moving part 27. In addition, when discharging the screen mask M from the printing machine 11 into the storage device 40, the printing machine 11 pushes out the used screen mask M to the handover layer 58 of the storage device 40 through the mask moving part 27. The storage device 40 can pull in the screen mask M by rotating the belt 45 in the direction opposite to the discharging direction. Thus, the printing machine 11, the storage device 40, and the automated guided vehicle 5 of the present embodiment can implement the automatic handling and automatic replacement of the screen mask M. In addition, as described above, the components for automatic replacement are not limited to the screen mask M. For example, as shown by the dotted arrow 28 in Figure 3 , the support block 39 can also be automatically replaced with the storage device 40.

[0037] (Operation guidance system 10) Figure 7 The block diagram showing the operation guidance system 10 is as follows. As Figure 7 shown, the production line management device 3 is, for example, a personal computer equipped with a control part 61 such as a CPU, a storage device 62, etc. The production line management device 3 manages the production in the production line 2 based on the production management plan of the substrate S managed by the overall management device 4. The storage device 62 is used for storing the production plan data 75 described later.

[0038] The overall management device 4 is, for example, a server device equipped with a control part 64 such as a CPU, a storage device 65, etc. The production management program 67, the boot program 68, the production plan DB 69, the task DB 70, and the instruction DB 71 are stored in the storage device 65. The production management program 67 is a program for managing the production order of each production line 2. The boot program 68 is a program for changing the information displayed on the display terminal 6, specifically the operation instruction information 73 described later, based on the information collected from the production line management devices 3 of each production line 2 (the lists L1 to L5 described later).

[0039] The data required to generate the production plan data 75 is stored in the storage device 65. Specifically, it is information on the substrate S and the models of each component. The model is, for example, information on the components (products) required for the substrate S for generating the production plan data 75. In the case of the substrate S, the model is information on the model name of the substrate S. In addition, in the case of the component being solder paste, the model is information on the model (product name, etc.) of the solder paste. The operator operates the management device 4, refers to the data in the storage device 65, and selects models such as the substrate type, solder type, and component type according to the production plan to generate the production plan data 75. The management device 4 generates the production plan data 75 based on the operator's operation input and registers it in the production plan DB 69. The production plan data 75 is, for example, information indicating which models of components to use for the production line 2, when to start producing the substrate S, and how many to produce. Therefore, information indicating production instructions for each device of the production line 2 such as the printing machine 11 and the mounting device 13 is stored in the production plan data 75. In the following description related to the production plan data 75, the description will be centered around the printing machine 11.

[0040] The production plan data 75 is managed, for example, using an identification number called a work order number. In the production plan data 75, for example, in addition to the above-mentioned models, information such as the task name, the planned number of production blocks, and the planned production start time is stored in association with the work order number (refer to Figure 8 ). In the model information, in addition to the information on the components and the substrate S models used in its production, such as the model of the solder paste mentioned above, information on models such as the squeegee 25 is also set. The task name is the name of the task data JOB. The task data JOB is control data for controlling each device (printing machine 11, mounting device 13) of the production line 2 in the production of this production plan data 75. In the case of the printing machine 11, the task data JOB is, for example, information on the starting position of the movement of the squeegee 25 corresponding to the size of the substrate S. In addition, in the case of the mounting device 13, the task data JOB is information on the mounting position of the components. For example, a plurality of task data JOBs corresponding to the type of the substrate S are stored in the task DB 70. Each device of the production line 2 obtains the task data JOB of the task name indicated by the production plan data 75 from the task DB 70 before starting production for use in production. The instruction DB 71 registers the operation instruction information 73 displayed on the display terminal 6. The planned production start time is the time when the production of the substrate S is planned to start. In addition, in this embodiment, for example, what represents an arbitrary point in time without a time span is called "XX moment", and what represents a specified time span is called "XX time" for explanation.

[0041] The display terminal 6 is a personal computer equipped with a CPU (not shown), etc., and includes a monitor 77, an input unit 78, and a storage device 79. The monitor 77 is, for example, an LCD panel. The input unit 78 is, for example, a mouse and a keyboard. The display terminal 6 acquires the operation instruction information 73 from the instruction DB 71, stores it in the storage device 79, and displays it on the monitor 77.

[0042] (Regarding the display of the operation instruction information 73) Next, use Figure 8 To describe the process of causing the operation instruction information 73 to be displayed on the display terminal 6 by the operation guidance system 10. In the following description, the device that executes the program is described by the device name and the program name. For example, "The production management program 67 writes to the production plan DB 69" means that the control unit 64 of the unified management device 4 that manages the production plan DB 69 writes to the production plan DB 69. In addition, in the following description, in order to avoid complicating the drawings, as Figure 8 Shown, the description is centered on the printing machine 11 of one production line 2. However, information can also be collected in the same way for the printing machines 11 of other production lines 2, and the operation instruction information 73 can be centrally displayed for each production line 2.

[0043] First, in Figure 8 In step (hereinafter, only recorded as S) 1 shown, the operator of the unified management device 4 registers new production plan data 75. The production management program 67 receives the operator's operation input (S1), generates production plan data 75 based on the received operation input, and registers the generated production plan data 75 in the production plan DB 69 (S3). As described above, for example, a work order number, a task name, a model number, a planned production quantity, and a planned production start time are set in the production plan data 75. In addition, the content of the above production plan data 75 is an example. For example, the production plan data 75 may also include information on the production line 2 that designates the production substrate S, such as the identification information of the designated production line 2.

[0044] The operator, for example, uses the unified management device 4 to confirm the progress of production of each production line 2 and sets the planned production start time of the production plan data 75. However, actual production may start earlier than expected, or may be delayed due to errors, etc., and cannot proceed according to the production plan. As a result, it is possible that the recovery or delivery of components is advanced and the unmanned transport vehicle 5 waits in front of the printing machine 11, or the recovery or delivery of components is delayed and the production efficiency decreases. Therefore, the operation guidance system 10 can perform further optimized recovery and delivery by displaying the operation instruction information 73 in consideration of the actual production status of the printing machine 11.

[0045] As Figure 7As shown, the printing press 11 stores, for example, two production plan data 75 in the storage device 35. These two production plan data 75 are the production plan data 75 for the current production and the production plan data 75 for the production scheduled to be carried out next. The printing press 11 obtains the production plan data 75 for the production after next corresponding to the end of the production based on the production plan data 75 for the current production (S5). The printing press 11 estimates, for example, the changeover adjustment time of the so-called changeover adjustment in which the type of the substrate S to be produced is changed due to the completion of the production of the substrate S, based on the number of production blocks scheduled for production based on the production plan data 75 for the current production, the number of substrates S for which production has been completed at the current time point among the scheduled production blocks, that is, the number of produced blocks, and the unit production time required to produce one substrate S. Specifically, the changeover adjustment time can be calculated by the following formula. Changeover adjustment time = (Scheduled production blocks - Produced blocks) * Unit production time

[0046] As the unit production time, for example, a set value (theoretical value, target value, etc.) preset according to the substrate type can be used, or an actual measured value (average value, etc.) measured during the production of the substrate S can be used. In addition, the unit production time is preferably set to a time that takes into account the cleaning time of the cleaning unit 32 in addition to the printing time for printing the substrate S. For example, the printing press 11 performs the cleaning of the cleaning unit 32 every four prints, and sets the time required for this cleaning operation as the cleaning time. In addition, the time required for one print is set as the printing time. In this case, the unit production time can convert the cleaning time into each block and is represented by the following formula. Unit production time = Printing time + Cleaning time / 4 As the unit production time for estimating the changeover adjustment time, the printing press 11 can also use the substantial unit production time that takes into account this cleaning time. The printing press 11 requests the production plan data 75 for the production after next from the production line management device 3, for example, at the time (before) that is a specified time back from the estimated changeover adjustment time, that is, the end time of the production (S5). The printing press 11 notifies the production line management device 3 of the work order number of the production plan data 75 for the current production and the information indicating the request.

[0047] If the production line management device 3 receives the requirement of S5 from the printing press 11, it acquires the next next production plan data 75 (S7) from the production plan DB69 based on the work order number, and sends it to the printing press 11 (S9). The method for acquiring the production plan data 75 is not particularly limited. For example, in acquiring the production plan data 75, the production line management device 3 may notify the overall management device 4 of the work order number received from the printing press 11, and receive an instruction on which work order number's production plan data 75 should be acquired as the next next production plan data 75. Alternatively, the production line management device 3 may acquire, in S7, the production plan data 75 with the earliest scheduled production start time among the production plan data 75 registered in the production plan DB69. In addition, the production line management device 3 may preferentially acquire the production plan data 75 attached with the identification number of the production line 2 managed by this device. In addition, the estimation of the changeover adjustment time may be performed by a device other than the printing press 11 (the production line management device 3, the overall management device 4). For example, the production line management device 3 may acquire the number of produced blocks from the printing press 11 to estimate the changeover adjustment time, and when it becomes the time that is a specified time back from the changeover adjustment time, acquire the next next production plan data 75 and send it to the printing press 11.

[0048] On the other hand, the printing press 11 appropriately generates five lists required for generating the job instruction information 73, and notifies them to the bootstrap program 68 (the overall management device 4) via the production line management device 3 (S11, S12). The overall management device 4 generates the job instruction information 73 based on this list (S15), and registers the generated job instruction information 73 in the instruction DB71 (S17). The five lists are, for example, the planned preparation list L1, the manual changeover adjustment requirement list L2, the planned component requirement list L3, the planned recovery requirement list L4, and the emergency component requirement list L5. In addition, when these lists are described collectively, they are described as lists L1 to L5. In addition, a part or all of the generation processing of the lists L1 to L5 may be performed by a device other than the printing press 11 (the production line management device 3, the overall management device 4). In addition, the printing press 11 may directly send the lists L1 to L5 to the overall management device 4 (the bootstrap program 68) without passing through the production line management device 3.

[0049] The planned preparation list L1 is a list of components that are newly required for the changeover adjustment and can be automatically replaced, i.e., the stencil mask M in this embodiment. The manual changeover adjustment requirement list L2 is a list of components that are newly required for the changeover adjustment and are manually replaced, i.e., components other than the stencil mask M in this embodiment. As described above, the printing press 11 estimates the changeover adjustment time by multiplying the difference between the predetermined number of production blocks and the number of produced blocks by the unit production time. If it becomes the time (before) that is a predetermined time back from the estimated changeover adjustment time, the printing press 11 acquires the task data JOB of the next production plan data 75. This predetermined time, like the planned component requirement list L3 described later, is preferably set to be longer than the time obtained by adding the preparation time T4 and the movement time T5 (refer to Figure 10 ). That is, as described later, preferably, the predetermined time is set such that the planned preparation list L1 and the manual changeover adjustment requirement list L2 can be generated / transmitted before the predetermined time in a manner that the components are delivered before the changeover adjustment time. The printing press 11 acquires the task data JOB based on the task name set in the production plan data 75. In addition, the timing of acquiring the task data JOB is not limited to the time that is a predetermined time ahead of the changeover adjustment time. For example, the printing press 11 can also acquire the task data JOB of the task name set in the acquired production plan data 75 (the next next production plan data 75) at the timing when it has acquired the production plan data 75 in S9. In this case, the printing press 11 can also generate the planned preparation list L1 and the manual changeover adjustment requirement list L2 described later and send them to the bootstrap 68 at the time when it has acquired the next next production plan data 75 or at the time when it has started the production of the previous production plan data 75 (the next production plan data 75) of the next next production plan data 75.

[0050] The printing machine 11 accesses, for example, the task DB 70 of the overall management device 4, and acquires the task data JOB that matches the task name set in the next production plan data 75. In the task data JOB, the names (models, etc.) of the components used when producing the substrate S using this task data JOB are set. Specifically, they are the names of the screen mask M, the support block 39, the solder paste, the squeegee 25, etc. The printing machine 11 detects the components with names different from the names of the components set in the task data JOB of the substrate S in the current production among the names of the components set in the task data JOB used in the next production, that is, the components newly required in the changeover adjustment (an example of the target components of the present disclosure). When the newly required component detected by the printing machine 11 is the screen mask M, the name of the screen mask M and the changeover adjustment time are written into the planned preparation list L1, and are sent to the bootstrap program 68 via the production line management device 3 (S11, S12). In addition, when the newly required component detected is a component other than the screen mask M, the printing machine 11 writes the name of the component (such as the squeegee 25) and the changeover adjustment time into the manual changeover adjustment request list L2, and sends it to the bootstrap program 68 via the production line management device 3 (S11, S12). In addition, the printing machine 11 uses the task data JOB to detect the newly required components, but is not limited to this. For example, the printing machine 11 can also use the production plan data 75 to detect the newly required components. The printing machine 11 can also detect the components with names different from the names of the components set in the production plan data 75 of the substrate S in the current production among the names of the components set in the production plan data 75 of the next production as the components newly required in the changeover adjustment.

[0051] Based on the planned preparation list L1 and the manual changeover adjustment request list L2 received from the printing machine 11, the bootstrap program 68 generates the job instruction information 73 (S15), and registers the generated job instruction information 73 in the instruction DB 71 (S17). The display terminal 6 accesses the instruction DB 71, for example, regularly. When the printing machine 11 detects the access of the display terminal 6, it acquires the job instruction information 73 (S19), and causes the monitor 77 (refer to Figure 7 ) to display a list of the job instruction information 73 (S21).

[0052] Figure 9 An example of the list of the job instruction information 73 displayed on the monitor 77 is shown. As Figure 9As shown, job name, target start time T3 of the job, work order number, part type, part model, destination, and information of target start time T2 are set in the job instruction information 73. The bootstrap program 68 arranges each piece of information in the job instruction information 73 in one line, arranges multiple job instruction information 73 vertically, and displays them at a glance on the display terminal 6. The job name is information indicating the type of the job of the job instruction information 73. In this embodiment, as the job name, automatic delivery, manual delivery, automatic recovery, and manual recovery are set. Automatic delivery indicates a job of delivering the part (hereinafter referred to as the target part) indicated by the job instruction information 73 by the automated guided vehicle 5. In this embodiment, the delivery of the stencil mask M belongs to automatic delivery. Manual delivery indicates a job in which an operator holds the target part and delivers it from the storage 8 to the printing press 11. In this embodiment, the squeegee 25, the cassette 36, the cleaning part 33, and the support block 39 belong to manual delivery. Automatic recovery indicates a job of recovering the stencil mask M from the printing press 11 to the storage 8 using the automated guided vehicle 5. Manual recovery indicates a job in which an operator manually recovers the target part other than the stencil mask M from the printing press 11 to the storage 8. In addition, the types of the above job names are just examples. For example, as the job name, only delivery and recovery can be set without distinguishing between automatic and manual.

[0053] Figure 10 Shows the relationship between each time and moment. The bootstrap program 68 obtains / sets the device required time T1 based on the received lists L1 to L5. The device required time T1 is the delivery time when a new target part needs to be delivered to the printing press 11, or the recovery time when a used target part needs to be recovered. The bootstrap program 68 sets, for example, the changeover adjustment time T6 (an example of the delivery time in the present disclosure) set in the planned preparation list L1 and the manual changeover adjustment requirement list L2 received from the printing press 11 as the device required time T1.

[0054] In the case of the planned preparation list L1, the AGV 5 delivers automatically. In the case of the manual changeover adjustment requirement list L2, the operator delivers by hand. Therefore, the guidance program 68 sets the movement time T5 required for the parts to be transported according to the planned preparation list L1 or the manual changeover adjustment requirement list L2. In the case of the planned preparation list L1, the guidance program 68 sets the time required for the AGV 5 to move from the storage 8 to the target printing press 11 as the movement time T5. The method for setting the movement time T5 is not particularly limited. For example, in the storage device 65, the movement time T5 required for the AGV 5 to move from the storage 8 to the printing press 11 of each production line 2 is set. In addition, the printing press 11 sets the information of its own device in the planned preparation list L1. Moreover, the guidance program 68 can also detect the destination printing press 11 based on the information of the device set in the planned preparation list L1, obtain and set the movement time T5 corresponding to the detected printing press 11 from the storage device 65. Similarly, in the case of the manual changeover adjustment requirement list L2, the guidance program 68 sets the time required for the operator to move from the storage 8 to the target printing press 11 as the movement time T5. The guidance program 68 sets the time obtained by backing up the movement time T5 from the device required time T1 (changeover adjustment time T6) as the departure target time T2 of the operation instruction information 73. That is, the guidance program 68 sets the time to depart from the storage 8 in a manner that can catch up with the changeover adjustment time T6 as the departure target time T2. As Figure 9 shown, the display terminal 6 displays the departure target time T2 in association with each operation instruction information 73.

[0055] In addition, the guidance program 68 sets the time obtained by backing up the preparation time T4 from the departure target time T2 as the operation start target time T3 of the operation instruction information 73. This preparation time T4 is the time required for the operator to prepare the parts to be processed. For example, in the case where the part to be processed is the screen mask M, the preparation time T4 is the time required for the operator to find the shelf in the storage 8 and take out the target screen mask M and place it on the AGV 5. In addition, in the case where the parts to be processed are the squeegee 25, the cleaning part 33, and the support block 39, the preparation time T4 is the time required for the operator to find the shelf in the storage 8 and take out the parts to be processed. In addition, in the case where the part to be processed is the solder paste, the preparation time T4 is the time to take out the solder paste stored in the refrigerator and restore it to room temperature and the time required for stirring. As such a preparation time T4, for example, a standard and ideal operation time can be set in advance. Or, as the preparation time T4, the measured value actually measured by the operator in the operation environment can also be set. As Figure 9 shown, the display terminal 6 displays the operation start target time T3 in association with each operation instruction information 73.

[0056] In addition, as Figure 9As shown, the component type of the operation instruction information 73 is information indicating the type of the target component (mask, support, etc.). The component model is information indicating the model of the target component. The bootstrap program 68 can set the information on these component types and component models in the operation instruction information 73 based on, for example, the names of the components set in the planned preparation list L1 and the manual changeover adjustment requirement list L2. In addition, the destination is the identification information of the production line 2 for the delivery destination and the recycling destination. The bootstrap program 68 can set the information on this destination based on the information of the source such as the planned preparation list L1, etc.

[0057] In addition, the planned component requirement list L3 is a list of target components that need to be regularly replaced due to consumption, etc. Among the components used in the printing machine 11, there are components that need to be replaced whenever a threshold number of substrates S are printed. For example, the solder mask M gradually adheres to the solder paste during repeated printing, so regular cleaning is required. For example, if the solder mask M is set to print 1000 substrates S, cleaning is required. In this case, after replacing the solder mask M, the planned replacement time T7 for the next replacement can be expressed by the following formula using the current time and the unit production time. This 1000 substrates is an example of the threshold number of substrates in the present disclosure. Planned replacement time T7 = current time + 1000 * unit production time

[0058] Similarly, when the cassette 36 prints a specified threshold number of substrates, the remaining amount is exhausted. The capacity of the solder paste loaded in the unused cassette 36 is used as the initial capacity. In addition, the amount of solder paste consumed in one printing is used as the expected consumption amount. In this case, after replacing the cassette 36, the planned replacement time T7 for the next replacement can be expressed by the following formula using the current time and the unit production time. Planned replacement time T7 = current time + (initial capacity / expected consumption amount) * unit production time The initial capacity can be preset according to the size of the cassette 36. The expected consumption amount can be preset based on the results of simulation and measured values. In this case, the value of (initial capacity / expected consumption amount) is an example of the threshold number of substrates in the present disclosure.

[0059] Similarly, for example, the cleaning member 33 is used in the cleaning process for every prescribed number of printed blocks, and if the prescribed threshold number of blocks is printed, it needs to be replaced with a new one. Therefore, similarly to the screen mask M, the threshold number of blocks that need to be replaced is multiplied by the unit production time, and the resulting value is added to the current time, whereby the planned replacement time T7 can be calculated. The printing machine 11 generates a planned component requirement list L3 and sends it at a time that is a prescribed time back from the planned replacement time T7 calculated by the above calculation. The prescribed time is preferably set to a time longer than the sum of the preparation time T4 and the movement time T5 of the target component. That is, preferably, the planned component requirement list L3 is generated / sent before the prescribed time so that the target component is delivered before the planned replacement time T7 of the target component. The printing machine 11 sets the planned replacement time T7 and the name of the target component that needs to be replaced in the planned component requirement list L3 and sends it to the bootstrap program 68. In addition, the timing of sending the planned component requirement list L3 is not limited to the time that is a prescribed time back from the planned replacement time T7. For example, the printing machine 11 may also calculate the planned replacement time T7 immediately after the target component is replaced, generate the planned component requirement list L3, and send it.

[0060] Similar to the planned preparation list L1, etc., the bootstrap program 68 sets the planned replacement time T7 of the planned component requirement list L3 as the device requirement time T1, sets the departure target time T2 and the operation start target time T3 to generate operation instruction information 73 (refer to Figure 10 ). Thus, as Figure 9 shown, it is possible to implement the arrangement for the delivery of the solder paste and the screen mask M.

[0061] The planned recovery requirement list L4 is a list of components that need to be recovered along with the production change adjustment. For example, when the printing press 11 reaches a time that is a specified time back from the production change adjustment time T6, it acquires the task data JOB of the next production plan data 75. As will be described later, in the case of only performing recovery, the preparation time T4 is poor, so this specified time is preferably a time longer than the moving time T5. That is, in order to be able to recover the target component before the production change adjustment time T6, it is preferable that the time to generate / send the planned recovery requirement list L4 can be before the specified time. The printing press 11 detects components with names different from those of the components set in the task data JOB of the substrate S currently in production, that is, components that need to be recovered during the production change adjustment (an example of the target component of the present disclosure). The printing press 11 sets the name of the detected component and the production change adjustment time T6 in the planned recovery requirement list L4, and sends it to the bootstrap program 68 via the production line management device 3 (S11, S12). The bootstrap program 68 sets the production change adjustment time T6 of the planned recovery requirement list L4 as the device requirement time T1, and generates job instruction information 73 with the departure target time T2 set.

[0062] In addition, similar to the planned preparation list L1 and the manual production change adjustment requirement list L2, the bootstrap program 68 changes the display of the Figure 9 job name to automatic recovery or manual recovery for the screen mask M that can be automatically recovered and the target components (other than the screen mask M) that must be manually recovered. For example, the bootstrap program 68 can also judge automatic recovery and manual recovery based on the name of the target component in the planned recovery requirement list L4, and generate the job instruction information 73. Thus, the bootstrap program 68 can set automatic recovery or manual recovery as the job name of the job instruction information 73 based on the information in the planned recovery requirement list L4, and can visibly display whether it is a target component that can be recovered by the automated guided vehicle 5 or a component that must be recovered manually by an operator. Alternatively, the printing press 11 can set information indicating whether it is manual recovery or automatic recovery in the planned recovery requirement list L4. In addition, similar to the planned preparation list L1 and the manual production change adjustment requirement list L2, the printing press 11 can also generate the planned recovery requirement list L4 by dividing it into two lists: the planned recovery requirement list L4 for automatic recovery and the planned recovery requirement list L4 for manual recovery.

[0063] In addition, in the case of only performing the recycling of the object part, the preparation time T4 in the storage 8 is no longer required. For example, in the previous production, the support block 39 was used, but in the next production when using a support pin, the support block 39 needs to be manually recycled. Or, in the case where the next production can be performed using the stencil mask M stored in the storage device 40, only the automatic recycling of the stencil mask M occurs. In this case, as shown in the third operation instruction information 73 from the top of Figure 9 , the bootstrap program 68 does not set the operation start target time T3, but only sets the departure target time T2. This departure target time T2 is the time obtained by tracing back the movement time T5 from the changeover adjustment time T6 of the planned recycling requirement list L4. In addition, in the case of only performing recycling by the automated guided vehicle 5, there is no need to set the storage 8 as the departure location, and the automated guided vehicle 5 can be made to move to the recycling location from any place in the production facility (floor). Therefore, for example, when there is an automated guided vehicle 5 moving towards the storage 8 without any load or an automated guided vehicle 5 stopped and standby in the production facility, the bootstrap program 68 can also set the time required for moving this automated guided vehicle 5 to the printing press 11 at the recycling destination as the movement time T5. In this case, the movement time T5 and the departure target time T2 can also be updated in accordance with the movement of the automated guided vehicle 5. In addition, in the case where automatic delivery and automatic recycling, or manual delivery and manual recycling can be implemented in one round trip, the bootstrap program 68 can also generate the delivery and recycling as one operation instruction information 73 and display it. For example, the operation name can be set to "Automatic Delivery / Recycling", and one operation instruction information 73 can be displayed across two lines.

[0064] The emergency part requirement list L5 is a list used when a part needs to be replaced earlier than expected. As described above, the printing press 11 estimates the planned replacement time T7 of the cartridge 36 based on the initial capacity, expected consumption amount, and unit production time of the solder paste, and generates the planned part requirement list L3. However, the solder paste may be consumed earlier than expected due to temperature, humidity, the shape of the squeegee 25, etc. As described above, the printing press 11 is equipped with a remaining amount detection sensor 36A for detecting the remaining amount of the solder paste in the cartridge 36. For example, when the remaining amount of the solder paste detected by the remaining amount detection sensor 36A reaches below a specified threshold amount, the printing press 11 sets the name of the solder paste in the emergency part requirement list L5. In addition, the printing press 11 sets the delivery time when the solder paste needs to be delivered as the emergency time T8 (refer to Figure 10 ) in the emergency part requirement list L5. The printing press 11 sends the generated emergency part requirement list L5 to the bootstrap program 68.

[0065] As the threshold amount stipulated above, it is preferably set to an amount such that the remaining amount is not zero before the new cartridge 36 is delivered. Specifically, for example, when the time from the point in time when the remaining amount becomes the threshold amount until the remaining amount becomes zero during continuous printing is set as the remaining time, a threshold amount that is equal to or greater than the total time of the preparation time T4 and the movement time T5 is preferable. In addition, the target components required in the emergency component requirement list L5 are not limited to solder paste. For example, when the cleaning component 33 is a component (such as cleaning liquid) that is consumed every predetermined time, the remaining amount of the cleaning component 33 can also be detected using a sensor or the like, and in the case where it is not earlier than expected, it can be requested through the emergency component requirement list L5.

[0066] The bootstrap program 68 sets the emergency time T8 of the received emergency component requirement list L5 as the device requirement time T1, and sets the preparation time T4 and the movement time T5 to generate the job instruction information 73. Thereby, in the case where the consumption amount of the target component is more than expected, it can be delivered before it is completely exhausted. The bootstrap program 68 separately executes the generation and display of the job instruction information 73 based on the above-mentioned lists L1 to L5 for each of the plurality of production lines 2, and displays them on the display terminal 6. As Figure 9 shown, the job instruction information 73 for each production line 2 is displayed in a list.

[0067] As described above, the bootstrap program 68 sets the time obtained by backing off the preparation time T4 required for the operator to prepare the target component from the departure target time T2 as the operator's job start target time T3. The bootstrap program 68 displays the job start target time T3 in association with the job instruction information 73. In addition, as Figure 9 shown, the bootstrap program 68 instructs the display terminal 6 to arrange and display the plurality of job instruction information 73 in ascending order of the job start target time T3 from top to bottom in a list. Thereby, it is possible to display in order from the job instruction information 73 that must start preparation earlier, that is, the job instruction information 73 with a high preparation priority.

[0068] In addition, the bootstrap program 68 arranges and displays the plurality of job instruction information 73 in ascending order of the departure target time T2 in a list. As Figure 9As shown, the guidance program 68 displays in ascending order of the job start target time T3 and in ascending order of the departure target time T2. For example, the guidance program 68 sets the ascending order of the job start target time T3 as the first priority. Next, for the job instruction information 73 with the same job start target time T3, it is displayed in ascending order of the departure target time T2. Thus, it is possible to display in sequence from the job instruction information 73 that must depart earlier, that is, the job instruction information 73 with a high priority of departure. In addition, when the guidance program 68 does not display the job start target time T3, it can also display by arranging the job instruction information 73 in ascending order of the departure target time T2. In addition, the display order is not limited to the above ascending order. The guidance program 68 can also display in descending order of the job start target time T3 and the departure target time T2. Or, the guidance program 68 can display in sequence from the one with an earlier generation time of the job instruction information 73 instead of ascending or descending order.

[0069] In addition, when the guidance program 68 receives Figure 9 a selection of the job instruction information 73 for which the operator starts preparing the target part among the multiple job instruction information 73 displayed on the Figure 9 screen, it causes the selected job instruction information 73 to be displayed in a way that can be distinguished from other job instruction information 73. For example, the display terminal 6 receives a selection of the job instruction information 73 for which the preparation has started from the list of job instruction information 73 shown in Figure 9 through the input unit 78. For example, when a job instruction information 73 is selected by the mouse or keyboard of the input unit 78 in the column of the job start target time T3 of any job instruction information 73, the display terminal 6 notifies the guidance program 68 of which job instruction information 73 has been selected. The guidance program 68 stores the fact that the preparation has started for the received job instruction information 73 in the instruction DB71. The guidance program 68 notifies the display terminal 6 of an instruction to change the display of the selected job instruction information 73. Figure 9 shows a state where the job instruction information 73 for the solder paste at the bottom is selected. For example, as shown in

[0070] In addition, the display terminal 6 can also change the display without notifying the bootstrap program 68. Further, the bootstrap program 68 and the display terminal 6 may not receive the selection of the job instruction information 73 for starting the preparation through the input unit 78. For example, the display terminal 6 can also receive the selection of the job instruction information 73 based on an operation of confirming (verifying) whether the object part to be prepared is the correct part. As Figure 1 shown, the display terminal 6 is provided with a barcode reader 6A, for example. The job guidance system 10 manages each object part using barcodes. When the barcode reader 6A of the display terminal 6 reads the barcode of the object part (such as the squeegee 25) prepared by the operator in the storage 8, it can be determined that the preparation of the job instruction information 73 consistent with the type of the object part is completed, and the color of the consistent job instruction information 73 is changed. Thus, it is possible to receive both whether the prepared object part is correct and the completion of the preparation of the object part. In addition, the bootstrap program 68 may not perform the above selection of the job instruction information 73 and the change of the display.

[0071] In addition, the bootstrap program 68 sets the time obtained by backing up the movement time T5 required for the automated guided vehicle 5 to move from the departure location (such as the storage 8) to the printing press 11 from the device requirement time T1 as the departure target time T2. Thus, on the basis of ensuring the required movement time T5, the departure target time T2 that is advanced in time can be guided. It is possible to make the automated guided vehicle 5 reach the printing press 11 more reliably before the device requirement time T1. In addition, as the movement time T5 of the automated guided vehicle 5, the bootstrap program 68 may not use the time for the automated guided vehicle 5 to move within the production facility, but use the time required for a person to transport the object part.

[0072] In addition, the printing press 11 estimates the changeover adjustment time T6 based on the number of produced blocks, the planned number of production blocks, and the unit production time, and notifies it to the bootstrap program 68 using a list L1 or the like. The bootstrap program 68 sets the changeover adjustment time T6 of the obtained list L1 as the device requirement time T1. Thus, it is possible to set the device requirement time T1 and the departure target time T2 that conform to the actual production progress of the printing press 11. In addition, the bootstrap program 68 may also perform the estimation of the device requirement time T1.

[0073] In addition, the bootstrap program 68 sets the parts required after the changeover adjustment (the parts in the planned preparation list L1 and the manual changeover adjustment requirement list L2) as the object parts to be delivered, and sets the parts no longer required after the changeover adjustment (the parts in the planned recycling requirement list L4) as the object parts to be recycled. Thus, it is possible to detect the parts changed according to the changeover adjustment and appropriately set the object parts to be delivered and recycled.

[0074] In addition, when a component that needs to be manually replaced in conjunction with a production change adjustment is set as a target component, the guidance program 68 displays the need for manual replacement in the work instruction information 73 for the set target component. Figure 9 As shown, the job guidance system 10 displays the text "manual delivery" as the job name. As a result, the operator can easily distinguish between the job instruction information 73 that needs to be manually replaced and the job instruction information 73 that is automatically replaced. The operator can consider the preparation of the subsequent job, such as whether the operator needs to move to the printing press 11 to perform the job. In addition, the guidance program 68 may not display Figure 9 The job name.

[0075] In addition, when generating the planned component request list L3, the printer 11 calculates the time obtained by multiplying the predetermined threshold number of blocks (the number of blocks that need to be cleaned, the number of blocks based on the consumption of solder paste) by the unit production time, and sets the time obtained by adding the current time to the calculated time as the planned replacement time T7. The guidance program 68 sets the planned replacement time T7 obtained in the planned component request list L3 as the device request time T1. In this way, the replacement time of the screen mask M that needs to be cleaned every time the threshold number of blocks is printed and the solder paste that has run out of remaining amount can be predicted and notified to the operator for preparation.

[0076] (Regarding the delivery and collection of the subject parts) Bootloader 68 Figure 9 The delivery of the receiving object parts and the start of the collection are shown in the list of the operation instruction information 73. Figure 9 As shown, the display terminal 6 displays a start button 81 on the right side of each of the plurality of work instruction information 73. When the operator completes the preparation for the target component (screen mask M) to be automatically delivered and sets it on the unmanned guided vehicle 5, the operator selects the start button 81 on the right side of the set work instruction information 73 using the input unit 78 (mouse, etc.). The display terminal 6 notifies the guidance program 68 of the work instruction information 73 for which the start button 81 is selected. The guidance program 68 causes the unmanned guided vehicle 5 to start from the storage 8 to the printing press 11 corresponding to the notified work instruction information 73. The guidance program 68 deletes the work instruction information 73 for which the start button 81 is selected from the instruction DB 71. In addition, the guidance program 68 notifies the display terminal 6 of an instruction to delete the display of the work instruction information 73. In this way, the delivery of one work instruction information 73 is completed.

[0077] Therefore, when the display terminal 6 receives a selection of the work instruction information 73 indicating that the preparation of the target component to be delivered has been completed by the operator, the guidance program 68 causes the unmanned guided vehicle 5 to depart from the storage 8 toward the printing press 11. Thus, the unmanned guided vehicle 5 can be caused to depart according to the completion of the preparation, and automatic replacement can be performed at an appropriate timing.

[0078] Similarly, when the operator finishes preparing the target part for manual delivery and it becomes in a state where it can be taken out, the operator selects the departure button 81 on the right side of the job instruction information 73 for which the preparation has been done. The guidance program 68 does not perform remote operation of the automated guided vehicle 5, but as in the case of automatic delivery, deletes and does not display the selected job instruction information 73. Thus, also in the case of manual delivery, deletion of the job instruction information 73 and the like can be performed according to the completion of the operator's preparation.

[0079] In addition, when the departure button 81 of the job instruction information 73 whose job name is automatic recovery is selected, the guidance program 68 causes the automated guided vehicle 5 to depart for recovery of the unnecessary stencil mask M in the same manner as in automatic delivery. In this case, as described above, when only recovery is performed by the automated guided vehicle 5, it is not necessary to set the storage 8 as the departure place, and the automated guided vehicle 5 can also depart from an arbitrary place in the production facility (floor). In addition, the operator can select the departure button 81 of the job instruction information 73 for manual recovery at the time point when the operator is ready to perform recovery for the job instruction information 73 whose job name is manual recovery, delete the job instruction information 73, and perform recovery.

[0080] In addition, in the present embodiment, the automated guided vehicle 5 is an example of the transfer device of the present disclosure. The storage 8 or the position of the automated guided vehicle 5 at the time of instructing recovery is an example of the departure place. The overall control device 4 is an example of the job guidance device. In addition, the squeegee 25, the cleaning member 33, the cassette 36, the support block 39, and the stencil mask M are examples of parts and target parts. The remaining amount detection sensor 36A is an example of the detection device. The guidance program 68 is an example of the required time acquisition unit, the setting unit, and the display instruction unit. The changeover adjustment times T6, the planned replacement time T7, and the emergency time T8 of the planned preparation list L1 and the manual changeover adjustment requirement list L2 are examples of the delivery times. The changeover adjustment time T6 of the planned recovery requirement list L4 is an example of the recovery time.

[0081] As described above, according to the above-described embodiment, the following effects are achieved. In one aspect of the present embodiment, the guidance program 68 acquires the delivery time (the changeover adjustment time T6 etc. of the planned preparation list L1) for delivering a new part to the printing machine 11, and the recovery time (the changeover adjustment time T6 of the planned recovery requirement list L4) for recovering the used part (S12). The guidance program 68 sets the departure target time T2 for departing from the departure place (the storage 8 etc.) toward the printing machine 11 in such a manner as to catch up with the acquired device requirement time T1 (S15). In addition, the guidance program 68 sets the information of the target part that needs to perform an operation (delivery, recovery) at the device requirement time T1 corresponding to the departure target time T2 ( Figure 9(job name, work order number, part type, part model, destination). The bootstrap program 68 makes the job instruction information 73 that associates the set departure target time T2 and the information of the target part, and displays a plurality of pieces of job instruction information 73 on the display terminal 6 in a list (S19, S21).

[0082] Here, even if the operator in the storage 8 prepares according to the production plan of the overall management device 4, the actual production operation may start earlier than expected, or may be delayed due to the occurrence of errors, etc., and sometimes may not proceed according to the production plan. In this case, when the delivery of the replaced part is delayed, there is a problem of production stoppage. In addition, if the delivery is too early, there is a problem of parts remaining on site. In contrast, the bootstrap program 68 obtains the lists L1 to L5 from the printing machine 11, sets the departure target time T2 and the job start target time T3, and displays them in a list as the job instruction information 73. Thus, the operator can perform preparations matching the progress of the actual production of the printing machine 11. The target parts can be delivered and retrieved in a more optimized manner.

[0083] In addition, the present disclosure is not limited to the above-described embodiments, and various improvements and changes can of course be made without departing from the gist of the present disclosure. For example, in the above-described embodiment, the bootstrap program 68 uses the job instruction information 73 to perform the delivery and retrieval of the target part, but it may also perform only one of the delivery or retrieval. Therefore, the bootstrap program 68 may also use at least one of the five lists L1 to L5 to generate and display the job instruction information 73. In the above-described embodiment, the printing machine 11 generates the lists L1 to L5, but any one of other devices such as the production line management device 3, the overall management device 4, and the display terminal 6 may obtain the required information (number of produced blocks, etc.) from the printing machine 11 to generate the lists L1 to L5. In addition, the bootstrap program 68 generates the job instruction information 73, but it may also be generated by any one of other devices such as the production line management device 3, the printing machine 11, and the display terminal 6 in the same manner as the bootstrap program 68. In addition, the display terminal 6 displays the job instruction information 73, but it may also be displayed on other devices, the production line management device 3, the overall management device 4, and the printing machine 11.

[0084] In addition, Figure 9The display screen showing a list of the operation instruction information 73 shown is an example. For example, there may be only one departure button 81. The guidance program 68 and the display terminal 6 may also, when the departure target time T2 of any operation instruction information 73 among the plurality of operation instruction information 73 is selected and the departure button 81 is selected, implement the departure of the unmanned guided vehicle 5 and the deletion of the operation instruction information 73 for the selected operation instruction information 73. In addition, for example, the guidance program 68 may also display the operation instruction information 73 whose departure target time T2 and operation start target time T3 are earlier than the current time differently from the other operation instruction information 73. That is, the operation instruction information 73 that is delayed by a predetermined time may be displayed in an emphasized manner.
