Description

  In the present invention, one or a plurality of component mounting machines are arranged along a board transfer line, or a work machine including the component mounting machine, a screen printing machine, a dispenser, or a board inspection machine is a predetermined machine. The present invention relates to a mounting board manufacturing apparatus and a component mounting machine arranged in order.

  Conventionally, in a mounting board manufacturing apparatus in which work machines are arranged along a board transfer line, when the type of board changes, the apparatus is stopped and the operator is stopped when the board currently being worked on is carried out. However, by manually selecting a production program corresponding to the type of board, the change of the transfer rail width of each work machine was adjusted. However, when it is configured to change the work machine according to the program selection of the operator while the apparatus is stopped as described above, the stop time and standby time of the mounting board manufacturing apparatus become longer and production is performed. There is a problem that efficiency is lowered and a defective product due to an operator's operation error may be produced.

For this reason, for example, as shown in the following Patent Document 1, in the assembly process of components on a printed circuit board, in a mounting machine that performs setup change operations such as switching various data necessary for production and adjusting the conveyance rail width, By using the means to know when to change the setup, the completion of the production plan currently in production is judged, and the mounting machine itself is configured to switch independently while referring to the production plan. As a result, a mounting machine with an automatic setup change function has been developed that reduces the load on the host computer to be controlled and reduces the time required for the setup change by reducing the signal exchange between the host computer and the mounting machine. ing.
Japanese Patent No. 2885483

  When the mounting machine itself is configured to switch independently while referring to the production plan as shown in Patent Document 1, the load on the host computer that controls the plurality of mounting machines is reduced. By reducing the exchange of signals between the host computer and the mounting machine, it is possible to shorten the time required for the setup change corresponding to the change in the type of components mounted on the printed circuit board to some extent. On the other hand, when the board is dropped or removed from the transfer line, or when the operator inserts the board into the transfer line and adds the board, the above-mentioned upper computer recognizes the board. If the planned number of transports differs from the number of boards actually transported to each work machine, an incorrect setup change is performed. Good there is a problem that occurs.

  The configuration is such that the product type information of the substrate carried into the work machine is read by a reading means, etc., and whether or not the setup change is performed individually is determined based on the product type information, thereby preventing the occurrence of the defective product. However, according to this configuration, for example, when a substrate of a different type is mixed when continuously transporting the same type of substrate, the setup change is performed when the substrate reaches the working machine. After performing the work, it is necessary to perform the setup change for returning to the previous work state again, and there is a problem that the production efficiency is lowered due to frequent repetition of the setup change work.

  The present invention has been made in view of the above points, and is capable of effectively preventing a reduction in production efficiency and the occurrence of defective products by performing a setup change corresponding to a substrate type at an appropriate time. It aims at providing an apparatus and a component mounting machine.

Measuring means, storage means for storing the expected number of carry-ins of the same type, setup change control means for automatically executing setup change of the work machine according to the type of board, and detection of the board detected by the detection means Based on the product type information, it comprises a judging means for judging whether or not the setup change of the work machine is required by the setup change control means and a calling means for calling the worker, and the judging means changes the setup of the work equipment. If it is confirmed that the actual number of carried-in boards measured by the measuring means is not less than the expected number of carried-in sheets of the same product stored in the storage means before determining that it is necessary, the production plan make a call of a worker by the call means it is determined that the work on the street is not in progress, when the actual substrate carry the number above it has been confirmed that less than the carrying-planned number of sheets, the setup change control The present invention is characterized in that the operation is continued without changing the setup by means.

According to a second aspect of the present invention, in the mounting substrate manufacturing apparatus according to the first aspect, the actual substrate measured by the measuring unit when the determining unit determines that the work implement needs to be replaced. If the fact that the carry-planned number of the same kind that have been stored in the carry-in number and the storage means does not match is confirmed, work in production as planned is determined not to be the progress of the workers by the call means When the call is made and it is confirmed that the actual number of loaded substrates matches the planned number of loaded substrates, the setup change by the setup change control means is executed.

When the determination means determines that the work equipment needs to be changed, When it is confirmed that the actual number of substrates carried in measured by the measuring means and the planned number of carry-ins of the same product stored in the storage means do not match, it is determined that the work is not progressing according to the production plan. Then, when the calling means calls the operator, and when it is confirmed that the actual number of loaded substrates matches the planned number of loading, the changeover by the changeover control means is executed. It is characterized by comprising.

In the invention according to claim 1 , before it is determined that the work machine needs to be replaced based on the substrate type information detected by the detecting means (that is , substrates of the same type are continuously loaded). and in that it has the state), the actual substrate carry number measured by the measuring means, when it is not less than the carrying projected number of the same kind which are stored in the storage means is confirmed, the work on the production plan It is possible to effectively prevent the occurrence of overproduction, etc., by calling the operator by determining that the process is not progressing, and reducing the production efficiency due to frequent setup changes. There is an advantage that it is possible to effectively prevent the occurrence of a defective product due to the replacement.

Are sequentially arranged along the transfer line of the substrate 3, and a substrate unloader 8 is disposed on the downstream side thereof.

  As shown in FIGS. 2 and 3, each of the above working machines includes a setup change mechanism 9 that automatically executes setup change corresponding to the type of substrate 3, a control unit 10 including a personal computer, and the like. In response to this, there is provided calling means 11 comprising an alarm device or the like for calling an operator. In addition, when the substrate 3 is continuously carried into the own equipment, the screen printing machine 4 arranged on the most upstream side of the transfer line inputs the planned number of carry-ins and enters the inside of the own equipment. An input means 13 having a function of reserving a board 3 of a new type to be carried in and instructing the change of the work machine in accordance with the operation of the operator is provided.

  The setup change mechanism 9 includes an actuator including a motor drive mechanism that changes the distance between the two substrate transfer conveyors by moving one of the pair of substrate transfer conveyors (movable conveyors) provided in each work machine, for example. Or a drive mechanism provided with an actuator for changing the installation position of a backup pin (not shown) for locking the substrate 3.

  A control unit 10 provided in the screen printing machine 4 is connected to the substrate carry-in machine 2 through information communication means 14 such as a LAN (Local Area Network) using a coaxial cable or an optical fiber, and also performs information communication. It is connected to the downstream working machine, that is, the dispenser 5 through the means 14 (see FIG. 2). Further, each work machine arranged on the downstream side of the screen printing machine 4, that is, the control unit 10 provided in the dispenser 5, the component mounting machine 6, and the reflow furnace 7 is connected to the upstream side via the information communication means 14. Are connected to the working machine and the downstream working machine (see FIG. 3).

  The detection means 1 provided in the substrate carry-in machine 2 is installed on the most upstream side of the transfer line by imaging ID information consisting of a barcode, QR code, data matrix or the like attached to the substrate 3. Information communication means which detects the type information of the work machine, that is, the substrate 3 carried into the screen printing machine 4, and sends this type information to the control unit 10 of the screen printing machine 4 mainly by a wired or wireless communication line. 14 to transmit via. Further, each work machine having a work machine on the downstream side has a detection means 1 composed of an imaging means for detecting the product type information by imaging the ID information of the substrate 3, and is detected by this detection means 1. The product type information of the substrate 3 is transmitted to the work machine on the downstream side via the information communication means 14.

  The control unit 10 of each working machine has a storage unit 15 for storing the product type information of the board 3 transmitted via the information communication unit 14 and a new product type in its own equipment based on the product type information of the board 3. Determining means 16 for determining whether or not the substrate 3 is in a state where it is carried in, and when it is determined by the judging means 16 that a new type of substrate 3 is being carried into the own equipment. In addition to controlling the setup change mechanism 9 so as to automatically change the setup of its own equipment, control is performed so that the product type information of the substrate 3 is transmitted to the downstream working machine via the information communication means 14 at a predetermined time. Based on the type information of the substrate 3 detected by the detecting unit 1 and the measuring unit 18 for measuring the number of substrates loaded of the same type continuously loaded into the equipment. ing.

  Based on the product type information of the substrate 3 transmitted through the information communication unit 14, the determination unit 16 is a production program used when the work is next performed on the substrate 3 carried into the own facility. When the name is read and this program name is different from the name of the currently used production program, or when it is confirmed that there is no production program currently in use at the time of start-up, etc. It is determined that it is necessary to perform setup change because the substrate 3 is in a state where it is carried into its own equipment, and this determination signal is output to the setup change control means 17.

  In addition, the determination unit 16 determines the production plan based on the determination result of whether or not a new product type is brought into the own equipment and the number of substrates carried in the same product type measured by the measurement unit 18. It is determined whether the work is progressing according to the production plan, and when it is determined that the work is not progressing according to the production plan, an abnormality has occurred by outputting a control signal for operating the calling means 11 It is comprised so that an operator may be notified.

  Specifically, based on the product type information of the substrate 3 detected by the detection unit 1 and transmitted to the own facility through the communication unit 14, the same type of substrate 3 is continuously carried into the own facility. Later, when it is determined that a new type of substrate 3 is in a state of being carried into the own equipment, the actual number of substrates carried in by the measuring unit 18 and the operation of the input unit 13 are determined in advance. The designated number of substrates 3 to be carried in is compared, and if it is confirmed that the actual number of substrates to be carried in does not match the number of substrates 3 to be carried in, the substrate 3 is dropped or removed. However, since it is considered that an abnormality such as mixing different types of substrates 3 into the same type of substrate has occurred, control for calling the operator by operating the calling means 11 is executed. Yes.

Further, based on the product information of the substrate 3 detected by the detection means 1, the same product stored in the storage device 15 when it is determined that the information matches the substrate information of the same product continuously carried into the work machine. Is compared with the actual number of carried-in boards measured by the measuring means 18, and when it is determined that the actual number of carried-in boards exceeds the planned number of carried-in sheets, that is, the substrates 3 of the same type are operated. A new type of board 3 is loaded into the work machine based on the type information of the board 3 detected by the detecting means 1 in a state in which the number of boards 3 to be carried in is specified, while being continuously carried into the machine. If it is determined that the actual number of loaded substrates measured by the measuring means 18 is in a state of being coincident with a predetermined number of scheduled loading in before being determined to be in the loaded state, the substrate 3 is being transferred. Same varieties Substrate 3 is added or for detection error and the like of the board type by the upper danger detecting means 1 is considered to have occurred, so that the control to call the operator by actuating the call means 11 is executed .

  The setup change control means 17 uses the input means 13 when it is determined by the determination means 16 that it is necessary to change the setup of its own equipment, or when an operator called in response to the operation of the call means 11 is used. Then, when an input operation for instructing the setup change is performed, the installation interval of the board transfer conveyor is changed in accordance with the width dimension of the board 3, and the component mounter 6 etc. in accordance with the size of the board 3. It is configured to perform setup change such as changing the installation position of the backup pin provided or changing the temperature profile in the reflow furnace 7.

  A basic control operation at the time of manufacturing a substrate executed by a work machine (in this embodiment, a screen printing machine 4) arranged on the most upstream side of the transfer line will be described based on a flowchart shown in FIG. When this control operation is started, after the type information of the next board 3 transmitted from the detecting means 1 is input (step S1), the type information of the board 3 is stored in the storage means 15 (step S2). Next, it is determined whether or not the estimated carry-in number using the input unit 13 has been input (step S3). If it is determined YES, the planned carry-in number is stored in the storage unit 15 (step S3). S4).

  Then, after reading the production program name corresponding to the product type information of the substrate 3 from the storage means 15 (step S5), the changeover control described later is executed (step S6), and the operation for the substrate 3, that is, the screen printing machine. In this case, an operation of applying the solder paste to the substrate 3 is executed (step S7). Further, after outputting the product type information of the substrate 3 detected by the detection means 1 provided in the own equipment to the dispenser 5 which is a downstream working machine (step S8), a carry-in permission signal for the substrate 3 is output from the dispenser 5. It is determined whether it has been output (step S9), and when it is determined YES, the substrate 3 is carried out to the dispenser 5 (step S10).

  Next, it is determined whether or not there is a reservation for the next product type, that is, a reservation for carrying in the substrate 3 of the new product type (step S11). If YES is determined, the process proceeds to step S2 and the substrate of the new product type is determined. Repeat step 3 If it is determined as NO in step S11 and it is confirmed that there is no reservation for loading a new type of substrate 3, it is determined whether or not the manufacturing operation of the substrate 3 is completed (step S12). If NO is determined in step S12, the process returns to step S1 to repeat the above operation, and the substrate manufacturing operation is terminated when it is determined YES in step S12.

  Next, a basic control operation at the time of manufacturing a substrate, which is executed in a working machine arranged on the downstream side of the screen printing machine 4, will be described based on a flowchart shown in FIG. When this control operation starts, after inputting the product type information of the substrate 3 to be carried into the own equipment next in accordance with the detection signal of the detection means 1 provided in the upstream work machine (step S21), this substrate 3 type information is stored in the storage means 15 (step S22). Next, after reading the production program name corresponding to the product type information of the substrate 3 from the storage means 15 (step S23), the changeover control described later is executed (step S24), and the operation on the substrate 3 (in the case of the dispenser 5). Then, a cream solder application operation, a component mounting operation in the case of the component mounting machine 6, and a post-processing operation after component mounting in the case of the reflow furnace 7 are executed (step S25).

  Moreover, after outputting the product type information of the board 3 detected by the detecting means 1 provided in the own equipment to the downstream working machine (step S26), a carry-in permission signal for the board 3 is outputted from the downstream work. (Step S27), and when it is determined YES, the substrate 3 is carried out to the downstream working machine (Step S28). Next, it is determined whether or not the manufacturing operation of the substrate 3 has been completed (step S29). If it is determined NO in step S29, the process returns to step S21 to repeat the above operation, and the substrate manufacturing operation is terminated when it is determined YES in step S29.

  Next, the control operation during the setup change control executed in step S6 of FIG. 4 and step S24 of FIG. 5 will be described based on the flowchart shown in FIG. When this control operation starts, first, the name of the production program read in step S5 or S23, that is, the name of the production program corresponding to the type of the board 3 that is in the state of being carried into the own equipment, It is determined whether or not it is necessary to perform setup change by bringing a new product type board 3 into the own equipment by comparing with the production program names of the other (step S31).

  When it is determined as YES in step S31 and it is confirmed that the production program corresponding to the new board 3 is different from the production program currently in use, and it is necessary to change the work machine. Determines whether or not the scheduled carry-in number specified in advance by the input unit 13 and the actual substrate carry-in number measured by the measuring unit 18 coincide with each other (step S32). It is determined whether or not work is in progress.

  Although it is determined as NO in step S32 and it is determined in step S31 that the setup change is necessary, the planned carry-in number differs from the actual substrate carry-in number, that is, the actual substrate carry-in. If it is determined that the number of sheets has not reached the planned number of sheets to be carried in, it is determined that the work is not progressing according to the production plan, and the calling means 11 is activated (step S33), and the operator is instructed to change the setup. If it is determined as NO (NO in step S34), the work implement is stopped until an appropriate process is performed by the worker (step S35).

  In addition, when it is determined as YES in step S34 and it is confirmed that the operator has instructed execution of the setup change by determining that the setup should be changed, or it is determined as YES in step S32 and carried in. The planned number of sheets and the actual number of substrates carried in are the same, that is, after the work of the number of sheets to be carried in is completed, a new type of board 3 is brought into the own equipment, and the work proceeds according to the production plan. If it is confirmed, the control signal instructing the setup change is output to the setup change mechanism 9 to execute the setup change (step S36), and the process returns.

  If it is determined NO in step S31 and it is confirmed that there is no state change, the actual number of loaded substrates measured by the measuring unit 18 is designated in advance by the input unit 13. It is determined whether or not the number is less than the planned carry-in number (step S37). Although it is determined NO in step S37 and it is determined in step S31 that there is no state to be changed, the actual number of loaded substrates is not less than the planned number of loaded substrates, that is, If it is determined that the actual number of loaded substrates matches or the actual number of loaded substrates is larger than the planned number of loaded substrates, it is determined that the operation is not progressing according to the production plan, and the calling means 11 is operated (step S38), and it is determined whether or not there has been an instruction to change the setup (step S39). If NO is determined, the operation is performed until an appropriate process is performed by the operator. The machine is stopped (step S40).

  On the other hand, when it is determined as YES in step S39 and it is confirmed that the operator is in a state to be changed and it is confirmed that the execution of the change is instructed, or YES is determined in step S37. As a result, if it is confirmed that the actual number of boards to be loaded has not reached the planned number of sheets to be loaded and the setup change is not in place and the work is progressing as planned, return to work. Continue.

  As described above, the detection means 1 for detecting the product type information of the substrate 3 carried into the work machine, and the same product type successively carried into the work machine based on the product type information of the board 3 detected by the detection means 1 The measuring means 18 for measuring the number of board carry-in, the planned carry-in number for the same product stored in the storage means 15 and the actual board carry-in number measured by the measuring means 18 are compared, and the work proceeds as planned. Since the determination means 16 for determining whether or not the operation is being performed and the call means 11 for calling the worker when the determination means 16 determines that the work is not progressing as planned in production, the board is provided. By performing the setup change corresponding to the product type 3 at an appropriate time, there is an advantage that it is possible to effectively prevent a decrease in production efficiency and generation of defective products.

  That is, the same type of substrate 3 is continuously carried into the work machine, and the substrate 3 is dropped or extracted in the state where the scheduled number of substrates 3 to be carried is specified, or the same type of substrate 3 When different types of substrates 3 are mixed in the substrate, when it is determined that a new type of substrate 3 is in a state of being loaded into the work machine, the number of previously designated loading- Since the actual number of loaded substrates measured by the measuring means 18 is different, it is possible to appropriately determine whether or not the work is proceeding according to the production plan by determining this state. When a new type of substrate 3 is brought into the work machine, the actual number of substrates carried in does not match the predetermined number of carry-ins, and the work is proceeding according to the production plan. If it is determined that there is not, the calling means 11 is activated and the worker is called, so that the worker determines whether the work should be continued or whether the setup change should be performed. Thus, it is possible to prevent generation of defective products and to perform setup change at an appropriate time.

  For example, when it is determined that a substrate 3 of a different type is mixed in a plurality of substrates of the same type as described above, and a new type of substrate 3 is brought into a work machine, When the work machine is replaced according to the determination result, it is necessary to perform the work on the different types of substrates 3 and then perform the replacement corresponding to the original substrate 3 again to return to the normal working state. In this case, only the work for the substrate 3 is stopped without performing the changeover corresponding to the substrate 3 of the different kind, because the changeover is frequently performed and the production efficiency is lowered. Thus, it is possible to suppress a decrease in production efficiency while preventing the generation of defective products. On the other hand, if it is determined that a new type of substrate 3 is brought into the working machine due to the dropout or extraction of the substrate 3, the setup change is performed at this time. Generation of insufficient production can be prevented by continuing the operation normally or adding the required number of substrates 3.

In addition, while the same type of substrate 3 is continuously carried into the work machine, the same type of substrate 3 is added while the substrate 3 is being transported in a state in which the planned number of substrates 3 to be carried is specified. before detection error breed information typographical error or means 1 detect the above carry-projected number is the like if it occurs, it is determined that the substrate 3 of the new varieties in a state of being carried on the work vehicle, Since the predetermined number of substrates 3 to be carried in advance and the actual number of substrates carried in measured by the measuring means 18 may coincide with each other, it is possible to work according to the production plan by determining this state. It is possible to appropriately determine whether or not the process is in progress. When it is determined that the work is not progressing according to the production plan due to the addition of the substrate 3 or the like, the calling means 11 is activated and the operator is called, If the worker decides whether or not to continue the setup, or whether or not the setup change should be performed, defective products may be generated due to incorrect setup change or overproduction may occur. There is an advantage that it can be effectively prevented.

  For example, before it is determined that the addition of the same type of substrate 3 to the same type of substrate 3 as described above causes the new type of substrate 3 to be carried into the working machine, it is designated in advance. When it is determined that the scheduled number of loaded substrates 3 and the actual number of loaded substrates measured by the measuring means 18 are in agreement, the work implement is changed according to the determination result. Since a defective product is manufactured, in this case, by removing the added substrate 3, it is possible to execute an operation on an appropriate number of substrates 3, or an operation on a substrate 3 of the same product type. By disabling the changeover of the work machine until the process is completed, defective products can be generated. On the other hand, before it is determined that a new type of substrate 3 has been brought into the working machine due to an input error or the like specifying the number of substrates 3 to be loaded to a value smaller than the regular value. When it is determined that the scheduled number of substrates 3 to be brought into coincidence with the actual number of substrates to be loaded, by prohibiting the changeover of the work machine until a new type of substrate 3 is loaded. The work can be continued efficiently.

  In particular, as shown in the above-described embodiment, when the input means 13 can be used to reserve the type of the substrate 3 that is newly carried into the substrate transfer apparatus, the work on the substrate 3 is performed in each work machine. In the meantime, based on the type information of the new board 3 that is reserved and input by the operator using the input means 13, whether or not it is necessary to execute the setup change of the own equipment is quickly and appropriately determined. If necessary, there is an advantage that the changeover of the work implement can be executed promptly.

  Further, as shown in the above embodiment, when the setup change mechanism 9 is configured to automatically execute the setup change of the work machine based on the product type information of the substrate 3 detected by the detection means 1, Compared to a configuration in which the setup is changed manually by the operator, the operation can be continued without the operator noticing the occurrence of defective products due to the fact that the operation does not proceed as planned. Therefore, whether or not the work is progressing according to the production plan based on the determination result of whether or not a new type of substrate 3 is brought into the work machine and the measurement result of the measuring means 18. There is an advantage that the effect obtained by determining is remarkably obtained.

  Furthermore, in the above-described embodiment, in the mounting substrate manufacturing apparatus in which a plurality of work machines are arranged along the transfer line of the substrate 3, the work machine (screen printing machine 4) installed on the most upstream side of the transfer line is loaded. A detection process for detecting the type information of the substrate 3 to be performed and whether or not it is necessary to change the setting of each work machine based on the type information of the board 3 detected in the detection process is determined for each work machine. When it is determined that it is necessary to perform the setup change of each work machine in this determination process, the setup change process including the setup change process for changing the setup of each work machine is performed. The setup change operation corresponding to the type of the substrate 3 can be properly executed in the own equipment without requiring a host computer for controlling and controlling the work machine.

  That is, in the screen printing machine 4 installed on the most upstream side of the transport line as in the above embodiment, it corresponds to the new substrate 3 read based on the product type information of the substrate 3 detected by the detecting means 1. It is determined whether or not the screen printing machine 4 is to be replaced by comparing the production program name with the name of the program currently in use, etc., and the working machine arranged on the downstream side of the screen printing machine 4 Then, the production program name corresponding to the new board 3 read based on the type information of the board 3 transmitted from the upstream work machine via the information communication means 14 and the program name currently in use are Since it is configured to determine whether or not to change the screen printing machine 4 by comparison or the like, it is possible to cope with a new type of substrate 3 without requiring a host computer. The setup change can be performed properly and quickly in the working machine. Therefore, there is an advantage that the work on the substrate 3 can be efficiently performed by the mounting substrate manufacturing apparatus while preventing the equipment cost of the mounting substrate manufacturing device suitable for the low-mix, low-volume production from increasing.

  Further, in the above embodiment, when the substrate 3 is present in the own equipment, after the operation on the substrate 3 is completed and the substrate 3 is carried out to the downstream working machine, the detection means 1 or the upstream Based on the type information of the board 3 transmitted from the work machine on the side, the program name corresponding to the type information of the new board 3 to be subsequently loaded into the own equipment is read, and this program name and the current own equipment are read. It is determined whether or not the program name corresponding to the type information of the existing board 3 is the same, and when the program names are different, the setup change mechanism 9 is operated to perform setup change. Since it comprised, the operation | work corresponding to the new board | substrate 3 carried in into an own equipment next can be performed rapidly and appropriately.

  In addition, it was comprised so that the product information of the board | substrate 3 might be detected by imaging ID information which consists of barcode etc. attached | subjected to the board | substrate 3 by the detection means 1 provided in the board | substrate carrying-in machine 2 of the uppermost stream side. In place of the above embodiment, the operator operates the input means 13 to input the product type information of the board 3, or reads the product ID of the setup item attached to the board rack or the board 3 by a handy barcode reader or the like. It may be configured to detect the type information of the substrate 3 conveyed to the screen printing machine 4 which is the most upstream working machine by reading by means. For example, when the input means 13 is used, the type list of the substrate 3 is displayed on the operation monitor provided in the screen printing machine 4 which is the most upstream side working machine, and the input type 13 is used to newly display the type list. For example, the type information of the substrate 3 conveyed to the work machine on the most upstream side may be detected by selecting the type of the correct substrate 3.

Furthermore, in the above-described embodiment, based on the type information of the substrate 3 detected by the detection unit 1, after the substrates 3 of the same type are continuously loaded into the work machine, a new type of board 3 is loaded into the work machine. Whether the work is progressing as planned by comparing the scheduled number of carry-in designated in advance with the actual number of carried-in substrates measured by the measuring means 18 at the time when it is determined And a comparison of the actual number of loaded substrates measured by the measuring means 18 with the same type of substrates 3 being continuously loaded into the working machine with a predetermined number of loaded loads. In the above description, the example in which both the control for determining whether or not the work is proceeding according to the production plan is executed has been described. However, only one of the two determination controls is executed. Good

  Further, the setup change mechanism 9 is operated in accordance with the control signal output from the setup change control means 17 to automatically execute the setup change such as changing the installation interval of the conveyer. In place of the above embodiment, when the setup information corresponding to the type of the new substrate 3 to be carried into the own equipment is different from the current setup information, the control signal output from the setup change control means 17 is used. In response to this, the notification means including a notification buzzer or a notification lamp is activated, and based on this notification, the operator drives the setup change mechanism 9 by manual operation, or the setup change such as replacing the tape feeder for supplying parts is performed. It may be configured to do.

  Furthermore, in the said embodiment, based on the board | substrate information detected by the detection means 1 provided in the upstream of own equipment, it is determined whether it is in the state in which the new board | substrate 3 is carried in in own equipment. In the mounting substrate manufacturing apparatus configured to transport various substrates 3 by a conveyor having a constant width dimension, detection means provided in its own equipment, such as a component, has been described. The number of boards 3 of the same type continuously carried into the own equipment is measured by the detecting means comprising the imaging means provided in the head unit of the mounting machine 6, and a new kind of board 3 is introduced into the own equipment. It may be determined whether or not is carried in. According to this configuration, when a new type of board 3 is carried into the facility, the setup change corresponding to the board 3 cannot be performed, and the setup change needs to be performed after the board 3 is carried out. For this reason, it is inevitable that a production failure occurs on at least one substrate 3. Therefore, as described above, the detection means 1 provided on the upstream side of the own facility or the information on the substrate 3 located on the transfer conveyor that connects the own facility and the work machine disposed on the upstream side is detected. It is desirable to determine whether or not a new substrate 3 is in a state where it is carried into the own facility based on the substrate information detected by the detecting means.

  Moreover, in the said embodiment, the screen printing machine 4 which apply | coats the solder paste which consists of a mixture of solder powder and a paste-form flux with respect to the board | substrate 3, and apply | coats cream solder etc. on the board | substrate 3 before the mounting process of components. A plurality of component mounting machines 6 for mounting a dispenser 5, a small piece of an IC, a transistor or a capacitor on the substrate 3, and a reflow furnace 7 for post-processing after mounting the components. Although the mounting substrate manufacturing apparatus in which the work machines are sequentially arranged along the conveyance line of the substrate 3 has been described, the present invention is not limited to this embodiment, and at least the component mounting machines 6 are arranged along the conveyance line of the substrate 3. The present invention can be applied to a mounting board manufacturing apparatus formed as described above. For example, a mounting board manufacturing apparatus in which only the component mounting machine 6 is disposed, or this component implementation A machine 6, the screen printer 4, also for at least one and is arranged mounted board manufacturing apparatus of the dispenser 5 or reflow furnace 7 is applicable to the present invention.
