Description

  The present invention relates to a component mounting line formed by connecting a plurality of work machines provided with a board transfer conveyor for transferring a board in the board transfer direction, and a board transfer method between the work machines.

The component mounting line is configured by connecting a plurality of component mounting-related work machines (for example, a component mounting machine, a screen printing machine, a board transfer device, etc.) having a transfer conveyor for transferring a board in the board transfer direction. In each work machine constituting the component mounting line, the operation control of the transfer conveyor included in the work machine is performed according to the position of the board conveyed by the transfer conveyor. Board detection means for outputting a detection signal corresponding to the control signal, and a control device for controlling the operation of the transfer conveyor based on the detection signal output from the board detection means. When it is detected by the substrate detection means that the substrate has been loaded from the upstream work machine, the control device starts the transport conveyor from the stopped state and carries the loaded substrate into the work machine.

  However, when transferring boards between adjacent work machines in the component mounting line, the work machine on the downstream side is that the board discharged from the work machine on the upstream side is actually put into the transport conveyor on the downstream side. Until this is detected by the substrate detection means, it is not possible to detect a state in which the substrate is about to be discharged from the upstream working machine. For this reason, when the transport conveyor provided in the downstream work machine is stopped when the substrate is put into the downstream work machine, the relative operating speed between the transport conveyors of both work machines becomes large, In some cases, the substrate could not be transferred smoothly.

  In order to improve the mounting production throughput in the component mounting line, it is effective to reduce the time required to transport the board to the work position of the work machine. For this purpose, in the process of transferring the board between work machines. Although it is desirable that the substrate can be stopped (standby) even if it is in a state of being straddled between the conveyors of adjacent work machines, the transport conveyor and the downstream provided in the upstream work machine are desirable. Since the operation control of the transfer conveyor provided in the work machine on the side is performed independently in both work machines, conventionally, the board is transported such that the board is stopped (standby) in a state straddling between the transfer conveyors of both work machines. The form could not be taken.

  Therefore, the present invention can smoothly transfer the substrates between adjacent work machines, and stops the board straddling between the transfer conveyors of both work machines in the process of transferring the boards. An object of the present invention is to provide a component mounting line and a substrate transfer method between work machines that can adopt such a substrate transfer mode.

Since the transfer conveyor can be activated in advance, the substrate can be transferred smoothly. In addition, by exchanging detection signals between the work machines, it is possible to perform synchronous control of the transfer conveyor, and the board straddling between the transfer conveyors of both work machines in the process of transferring the boards. The board can be transported in a stopped state (standby), so that the time required to transport the board to the working position of the work machine can be shortened, and as a result, the mounting production throughput is improved. be able to. Here, the detection signal output from one work implement does not pass through the control device provided in the one work implement (and thus the software provided in the work implement), and the control device of another work implement directly adjacent thereto. Therefore, it is difficult to cause a delay (time lag) in the transmission of the detection signal between the work machines, and synchronous control of the transfer conveyor between the work machines can be performed with extremely high accuracy.

When the inspection light is emitted to the “start position” and the inspection light is blocked by the substrate PB, a detection signal of the substrate PB is output. This detection signal is input to the input device control device 24 via the input device first sensor signal transmission path 21 a that connects the input device first sensor 21 and the input device control device 24. When the leading portion of the substrate PB passes the “starter transfer conveyor start start position”, the detection signal output from the input machine first sensor 21 is switched from OFF to ON before and after the pass, so the input machine control device 24 When the output of the detection signal from the input machine first sensor 21 is switched from OFF to ON, the board PB inserted into the input machine transfer conveyor 20 by the operator (or supplied from another apparatus on the upstream side) It can be detected that the leading portion has reached the “starting machine conveyor start position”.

When the leading portion of the substrate PB passes the “mounting machine transport conveyor start start position”, the detection signal output from the input machine second sensor 22 is switched from OFF to ON before and after the passage, so that the input machine control device 24 When the output of the detection signal from the input machine second sensor 22 is switched from OFF to ON, the leading portion of the substrate PB transferred by the input machine transfer conveyor 20 has reached the “mounting machine transfer conveyor start start position”. Can be detected.

In FIG. 1, the component mounting machine 3 includes a mounting machine transport conveyor 30 that transports the board PB, and four board detection sensors (mounting) that output detection signals according to the position of the board PB transported by the mounting machine transport conveyor 30. Machine first sensor 31, mounting machine second sensor 32, mounting machine third sensor 33
And a mounter board detection means 35 comprising a mounter fourth sensor 34), a substrate supporter 36 provided so as to be movable up and down with respect to the mounter transport conveyor 30, and movably provided with respect to the mounter transport conveyor 30. Based on the detection signal output from the mounting head 37 for mounting the component P on the board PB positioned at the component mounting position and the mounting machine board detecting means 35, the operation control of the mounting machine conveyor 30 is performed. At the same time, a mounting machine control device 38 is provided for controlling the raising / lowering operation of the substrate supporter 36 and controlling the mounting operation of the component P on the substrate PB by the mounting head 37.

  The mounting machine conveyor 30 has a configuration in which a conveyor belt 30c is stretched between a driving pulley 30a and a driven pulley 30b. The mounting machine controller 38 operates an operation of a driving motor 39 connected to the driving pulley 30a. The drive pulley 30a is operated by performing control, and the conveyor belt 30c is advanced in a certain direction to carry the substrate PB.

  The mounting machine first sensor 31, the mounting machine second sensor 32, the mounting machine third sensor 33, and the mounting machine fourth sensor 34 constituting the mounting machine board detection unit 35 are arranged in this order in the transport direction of the board PB. It has been.

  The mounting machine fourth sensor 34 is a “mounting board” which is the position of the leading portion of the board PB when the board PB transported by the mounting machine transport conveyor 30 reaches the component mounting position where the parts are mounted on the board PB. When the inspection light is emitted to the “stop position” and the inspection light is blocked by the substrate PB, a detection signal of the substrate PB is output. This detection signal is input to the mounting machine control device 38 via the mounting machine fourth sensor signal transmission path 34 a that connects the mounting machine fourth sensor 34 and the mounting machine control device 38. When the leading portion of the board PB passes the “mounting board stop position”, the detection signal output from the mounting machine fourth sensor 34 is switched from OFF to ON before and after the passage, so that the mounting machine control device 38 When the output of the detection signal from the four sensors 34 is switched from OFF to ON, it can be detected that the leading portion of the substrate PB received from the substrate loading machine 2 has reached the “mounting substrate stop position”.

  The mounting machine third sensor 33 emits inspection light to a “mounting board deceleration start position” which is a position immediately before the leading portion of the board PB transported by the mounting transport conveyor 30 reaches the “mounting board stop position”. When the inspection light is blocked by the substrate PB, a detection signal for the substrate PB is output. This detection signal is input to the mounting machine control device 38 via the mounting machine third sensor signal transmission path 33a that connects the mounting machine third sensor 33 and the mounting machine control device 38. When the leading portion of the board PB passes the “mounting board deceleration start position”, the detection signal output from the mounting machine third sensor 33 is switched from OFF to ON before and after the passage. When the output of the detection signal from the third sensor 33 is switched from OFF to ON, it can be detected that the leading portion of the substrate PB received from the substrate loading machine 2 has reached the “mounting substrate deceleration start position”. .

The mounting machine second sensor 32 has reached the standby position before the board PB transported by the mounting machine transport conveyor 30 reaches the component mounting position and does not overlap the board PB positioned at the component mounting position. The inspection light is emitted to the “standby substrate stop position”, which is the position of the leading portion of the substrate PB at that time, and a detection signal of the substrate PB is output when the inspection light is blocked by the substrate PB. This detection signal is input to the mounting machine control device 38 via the mounting machine second sensor signal transmission path 32a that connects the mounting machine second sensor 32 and the mounting machine control device 38. When the leading portion of the board PB passes the “standby board stop position”, the detection signal output from the mounting machine second sensor 32 is switched from OFF to ON before and after the passing, so that the mounting machine control device 38 2 When the output of the detection signal from the sensor 32 is switched from OFF to ON, it can be detected that the leading portion of the substrate PB received from the substrate loading machine 2 has reached the “standby substrate stop position”. Note that when the substrate PB reaches the “standby substrate stop position”, the substrate PB is in a state of straddling both the loading machine transport conveyor 20 and the mounting machine transport conveyor 30.

  The mounting machine first sensor 31 is a “standby substrate deceleration start position” that is a position immediately before the leading portion of the substrate PB put into the mounting machine transport conveyor 30 from the loading machine transport conveyor 20 reaches the “standby board stop position”. When the inspection light is emitted to the substrate PB and the inspection light is blocked by the substrate PB, a detection signal is output to the substrate PB. This detection signal is input to the mounting machine control device 38 via the mounting machine first sensor signal transmission path 31a that connects the mounting machine first sensor 31 and the mounting machine control device 38. When the leading portion of the substrate PB passes the “standby substrate deceleration start position”, the detection signal output by the mounting machine first sensor 31 is switched from OFF to ON before and after the passage, so that the mounting machine control device 38 When the output of the detection signal from the first sensor 31 is switched from OFF to ON, it is detected that the leading portion of the substrate PB sent from the substrate loading machine 2 has reached the “standby substrate deceleration start position”. Can do. Further, when the rear end portion of the substrate PB completely transferred from the substrate loading machine 2 to the mounting machine transport conveyor 30 passes the “standby substrate deceleration start position”, the detection output from the mounting machine first sensor 31 before and after the passage. Since the signal is switched from on to off, the mounting machine controller 38 switches the board PB from the board loading machine 2 to the mounting machine transport conveyor when the output of the detection signal from the mounting machine first sensor 31 is switched from on to off. It is possible to detect the complete transfer to 30.

  The substrate supporter 36 is moved up and down by a substrate supporter lifting mechanism 40 whose operation is controlled by the mounting machine control device 38. Based on the detection signal output from the mounting machine fourth sensor 34, the mounting machine control device 38 detects that the leading portion of the board PB transported by the mounting machine transport conveyor 30 has reached the “mounting board stop position”. In this case, the operation of the mounting machine transport conveyor 30 is stopped, and the board supporter 36 is lifted to support the board PB stationary at the component mounting position from below, so that the board PB is separated from the mounting machine transport conveyor 30. To. Thereby, the board PB is positioned at the component mounting position.

  The mounting head 37 includes a suction nozzle 37a that sucks the component P, and is moved relative to the substrate PB positioned by the substrate supporter 36 by a mounting head operating mechanism 41 whose operation is controlled by the mounting machine control device 38. . Further, the mounting head operating mechanism 41 also performs control of suction (and removal) of the component P by the suction nozzle 37a. After positioning the board PB at the component mounting position as described above, the mounting machine control device 38 controls the operation of the mounting head operating mechanism 41 and executes the component mounting process by the mounting head 37. This component mounting process is roughly the movement of the mounting head 37 to a component supply device (not shown), the suction of the component P supplied by the component supply device to the suction nozzle 37a, the movement of the mounting head 37 above the substrate PB, and the substrate PB. It consists of each process of mounting the component P on the top (detaching the component P from the suction nozzle 37a).

  As described above, the input machine second sensor signal transmission path 22 a connects the input machine second sensor 22 and the input machine control device 24 and outputs the detection signal output from the input machine second sensor 22. However, the input machine second sensor signal transmission path 22a is also connected between the input machine second sensor 22 and the mounting machine control device 38, and the detection signal output from the input machine second sensor 22 is controlled by the mounting machine. It is also transmitted to the device 38 (FIG. 1). That is, the loading machine second sensor signal transmission path 22a does not pass the detection signal output from the loading machine board detection means 23 provided in the board loading machine 2 via the control device (the loading machine control device 24) of the board loading machine 2. It is a signal transmission means for transmitting to the control device (mounting machine control device 38) of the component mounting machine 3.

Also, the mounting machine first sensor signal transmission path 31 a transmits the detection signal output from the mounting machine first sensor 31 to the mounting machine control apparatus 38 by connecting the mounting machine first sensor 31 and the mounting machine control apparatus 38. However, the mounting machine first sensor signal transmission path 31a is also connected between the mounting machine first sensor 31 and the loading machine control device 24, and the detection signal output by the mounting machine first sensor 31 is sent to the loading machine control device 24. Is also transmitted (FIG. 1). Further, the mounting machine second sensor signal transmission path 32 a transmits the detection signal output from the mounting machine second sensor 32 to the mounting machine control apparatus 38 by connecting the mounting machine second sensor 32 and the mounting machine control apparatus 38. However, the mounting machine second sensor signal transmission path 32 a is also connected between the mounting machine second sensor 32 and the input machine control device 24, and the detection signal output from the mounting machine second sensor 32 is sent to the input machine control device 24. Is also transmitted (FIG. 1). That is, the mounting machine first sensor signal transmission path 31a and the mounting machine second sensor signal transmission path 32a receive the detection signal output from the mounting machine board detection means 35 provided in the component mounting machine 3 as a control device (mounting). It is a signal transmission means for transmitting to the control device (the input device control device 24) of the substrate input device 2 without going through the input device control device 38).

  Next, the operation of the component mounting line 1 in the present embodiment will be described. When the above-described component mounting process is performed in the component mounting machine 3, the operator inserts the board PB to be mounted next into the input machine transport conveyor 20 in a stopped state. When the leading portion reaches the “starter transfer conveyor start position” (FIG. 2A), the output of the detection signal from the inputer first sensor 21 is switched from OFF to ON (time T1 in FIG. 4), Upon detecting that the leading part of the substrate PB has reached the “starter transfer conveyor start position” based on the switching of the output of the detection signal, the inputer controller 24 starts the inputer transfer conveyor 20 (in FIG. 4). Time T1). As a result, the transfer of the substrate PB by the input device transfer conveyor 20 is started, and the substrate PB is transferred into the substrate input device 2.

  When the leading portion of the substrate PB transported by the feeder transport conveyor 20 reaches the “mounting machine transport conveyor start start position” (FIG. 2B), the detection signal output from the feeder second sensor 22 is turned off. Switching on (time T2 in FIG. 4), on the basis of the switching of the output of the detection signal, the loading machine control device 24 that has detected that the leading portion of the substrate PB has reached the “mounting machine transport conveyor start start position” The mounting machine control device 38 that detects that the board PB is about to be discharged from the loading machine conveyor 20 and also detects that the top part of the board PB has reached the “mounting machine conveyor conveyor start start position” is stopped. The mounting machine transport conveyor 30 in the state is activated (time T2 in FIG. 4). By starting up the mounting machine transport conveyor 30, the relative operating speed between the loading machine transport conveyor 20 and the mounting machine transport conveyor 30 can be reduced, and the substrate PB discharged from the loading machine transport conveyor 20 can be transferred to the mounting machine transport conveyor. 30 can be transferred smoothly. Until the substrate PB is completely transferred from the loading machine conveying conveyor 20 to the mounting machine conveying conveyor 30, the substrate PB is in a state of straddling both the loading machine conveying conveyor 20 and the mounting machine conveying conveyor 30. It is conveyed by 20,30.

  As described above, in the component mounting line 1 according to the present embodiment, the control device (mounting device control device 38) of the work machine (component mounting device 3) on the downstream side is connected to the signal transmission means (the input device second sensor signal transmission path 22a). The substrate PB is about to be discharged from the transfer conveyor (loader transfer conveyor 20) provided in the upstream work machine based on the detection signal transmitted from the upstream work machine (substrate input machine 2) via The state is detected, and the conveyance conveyor (mounting machine conveyance conveyor 30) provided in the work machine on the downstream side is started from the stopped state.

  When the leading portion of the substrate PB transported across both the feeder transport conveyor 20 and the mounter transport conveyor 30 reaches the “standby substrate deceleration start position” (FIG. 2C), the mounter first sensor The detection signal output from 31 is switched from OFF to ON (time T3 in FIG. 4), and based on the detection signal output switching, it is detected that the leading portion of the substrate PB has reached the “standby substrate deceleration start position”. The mounting machine control device 38 decelerates the operating speed of the mounting machine transport conveyor 30 (that is, the transport speed of the substrate PB), and the loading machine control device 24 decelerates the operating speed of the loading machine transport conveyor 20 (time in FIG. 4). T3).

  As described above, in the component mounting line 1 according to the present embodiment, the control device (the input device control device 24) of the upstream work machine (the substrate input device 2) is connected to the signal transmission means (the first mounting device sensor signal transmission path 31a). ) Through the downstream work machine (component mounting machine 3), and the downstream work machine includes the transport conveyor (the input machine transport conveyor 20) provided in the upstream work machine. The speed is decelerated in synchronization with the conveyor (mounting machine conveyor 30).

  When the board PB transported in a state straddling both the feeder transport conveyor 20 and the mounting machine transport conveyor 30 further proceeds, and the leading portion of the board PB reaches the “standby board stop position” (FIG. 2D). The output of the detection signal from the mounting machine second sensor 32 is switched from OFF to ON (time T4 in FIG. 4), and the front end of the substrate PB is set to the “standby substrate stop position” based on the switching of the output of the detection signal. The mounting machine control device 38 that has detected the arrival stops the operation of the mounting machine transport conveyor 30, and the input machine control device 24 stops the operation of the input machine transport conveyor 20 (time T4 in FIG. 4). As a result, the board PB stops at a standby position across both the loading machine conveyor 20 and the mounting machine conveyor 30, and is loaded into the board loading machine 2 one before, and the component mounting machine 3 currently performs the component mounting process. A standby state is entered to wait for the component mounting process for the board PB being performed to end.

  As described above, in the component mounting line 1 according to the present embodiment, the control device (the input device control device 24) of the upstream working machine (the substrate input device 2) is connected to the signal transmission means (the mounting device second sensor signal transmission path 32a). ) Through the downstream work machine (component mounting machine 3), and the downstream work machine includes the transport conveyor (the input machine transport conveyor 20) provided in the upstream work machine. By stopping in synchronization with the conveyor (mounting machine transport conveyor 30), the substrate PB is transported by the upstream work machine (loader transport conveyor 20) and the transport conveyor (mounting machine transport) provided by the downstream work machine. It stops in the state straddling the conveyor 30).

  It is to be noted that the substrate PB is not placed in the intermediate portion of the charging machine transport conveyor 20 but is placed on standby between the charging machine transport conveyor 20 and the mounting machine transport conveyor 30 as described above. The transport distance when transporting the (standby board) to the component mounting position (working position) of the component mounting machine 3 is shortened, and the time required to position the standby board at the component mounting position (that is, the board PB to the component mounting position). This is because the time required for conveyance) can be shortened.

  When the component mounting process for the board PB on which component mounting is performed in the component mounting machine 3 is completed, the mounting machine control device 38 lowers the board supporter 36 and places the board PB on the mounting machine transport conveyor 30 (FIG. 2 ( e) and time T5) in FIG.

  When the board PB for which the component mounting process has been completed is placed on the mounting machine transport conveyor 30, the mounting machine control device 38 starts the mounting machine transport conveyor 30, and the input machine control device 24 starts the input machine transport conveyor 20 (FIG. 4 at time T6). Thereby, simultaneous conveyance of both the board PB (the board PB that has finished the component mounting process) mounted on the mounting machine transport conveyor 30 after component mounting and the board PB waiting in the standby position is started.

Simultaneous transfer of both the substrate PB on the mounting machine transfer conveyor 30 and the substrate PB waiting at the standby position is started, and the rear end portion of the substrate PB positioned at the standby position becomes the “standby substrate deceleration start position”. When reaching (FIG. 3A), the output of the detection signal from the mounting machine first sensor 31 is switched from ON to OFF (time T7 in FIG. 4), and the position is set at the standby position based on the switching of the output of the detection signal. The input machine control device 24 detected by the input machine control device 24 that the transferred substrate PB has completely transferred to the mounting conveyance conveyor 30 stops the operation of the input machine conveyance conveyor 20 (time T7 in FIG. 4).

  After the operation of the loading machine transport conveyor 20 is stopped, when the leading portion of the substrate PB transported by the mounting machine transport conveyor 30 reaches the “mounting board deceleration start position” (FIG. 3B), the mounting machine third The output of the detection signal from the sensor 33 is switched from OFF to ON (time T8 in FIG. 4), and based on the switching of the output of the detection signal, the leading portion of the board PB has reached the “mounting board deceleration start position”. The detected mounting machine control device 38 decelerates the operating speed of the mounting machine transport conveyor 30 (that is, the transport speed of the substrate PB) (time T8 in FIG. 4). In the present embodiment, when the leading portion of the board PB reaches the “mounting board deceleration start position”, the board PB that has finished component mounting has been completely discharged from the mounting machine transport conveyor 30. (See FIG. 3B).

  When the board PB transported by the mounting machine transport conveyor 30 further advances and the leading portion of the board PB reaches the “mounting board stop position” (FIG. 3C), the detection signal from the mounting machine fourth sensor 34 is detected. When the output is switched from OFF to ON (time T9 in FIG. 4), the mounter control device 38 that detects that the leading portion of the substrate PB has reached the “mounting substrate stop position” based on the switching of the output of the detection signal is Then, the operation of the mounting machine transport conveyor 30 is stopped (time T9 in FIG. 4). As a result, the substrate PB stops at the component mounting position.

  When the board PB is stationary at the component mounting position, the mounting machine control device 38 raises the board supporter 36 to position the board PB as described above (FIG. 3D), and operates the mounting head 37 to operate the component. The mounting process is started (time T10 in FIG. 4, and thereafter returns to time T1 in FIGS. 2A and 4).

  As described above, the component mounting line 1 according to the present embodiment corresponds to the position of the transport conveyor (the feeding machine transport conveyor 20 or the mounter transport conveyor 30) that transports the board PB and the position of the board PB transported by the transport conveyor. Substrate detection means (input machine substrate detection means 23 or mounting machine board detection means 35) that outputs a detection signal and a control device that controls the operation of the transfer conveyor based on the detection signal output from the substrate detection means (input machine control device) 24 or a mounting machine control device 38) are connected to each other in the conveyance direction of the board PB. The detection signal output from the board detection means included in the work implement is transmitted to the control device of another work implement adjacent to the one work implement without passing through the control device of the one work implement. The control device of the other work machine includes a signal transmission unit, and starts, decelerates, or stops the transfer conveyor included in the other work machine based on the detection signal transmitted from the one work machine via the signal transmission unit. It is like that.

  In addition, the transfer method between the work machines (the board loading machine 2 and the component mounting machine 3) in the present embodiment uses the detection signal output from the board detection means provided in one work machine as a control device for one work machine. The control device of the other work machine transmits the signal to the control device of the other work machine without passing through, and starts and decelerates the conveyance conveyor of the other work machine based on the detection signal transmitted from the one work machine. Or it stops.

  Specifically, in the present embodiment, the control device (mounting machine control device 38) of the component mounting machine 3 (other working machine) adjacent to the downstream side of the board loading machine 2 (one working machine) Based on the detection signal transmitted from the substrate loading machine 2 through the transmission means (the loading machine second sensor signal transmission path 22a), the substrate PB will be discharged from the transfer conveyor (the loading machine transfer conveyor 20) of the substrate loading machine 2. This state is detected, and the conveying conveyor (mounting machine conveying conveyor 30) provided in the component mounting machine 3 is activated from the stopped state.

Further, the control device (the input device control device 24) of the substrate input device 2 (the other operation device) adjacent to the upstream side of the component mounting machine 3 (the one operation device) is a signal transmission means (the first sensor signal of the mounting device). On the basis of the detection signal transmitted from the component mounting machine 3 (one work machine) via the transmission path 31a and the mounting machine second sensor signal transmission path 32a), the transfer conveyor (the input machine transfer conveyor 20) included in the board input machine 2 is provided. ) Is decelerated and stopped in synchronization with the transport conveyor (mounter transport conveyor 30) provided in the component mounter 3, so that the board PB is stopped in a state of straddling the feeder transport conveyor 20 and the mounter transport conveyor 30. It has become.

  As described above, in the component mounting line 1 according to the present embodiment, the detection signal output from the board detection unit included in one work machine is transmitted to the other work machines adjacent to each other without passing through the control device of the one work machine. Based on the detection signal transmitted from the one work machine, the control apparatus of the other work machine starts, decelerates, or stops the transfer conveyor provided in the other work machine. For this reason, when the board PB is transferred between adjacent work machines, the work machine on the downstream side (component mounting machine 3 in the present embodiment) is the work machine on the upstream side (board feeding machine 2 in the present embodiment). Before the substrate PB is actually loaded, it is possible to detect a state in which the substrate PB is about to be discharged from the upstream working machine, and the transport conveyor (the mounting machine transport conveyor 30 in the present embodiment) is set in advance. Since it can be started, the board | substrate PB can be delivered smoothly. In addition, it is possible to perform synchronous control of the transfer conveyor by exchanging detection signals between the work machines, and the transfer conveyors (the input machine transfer conveyor 20 and the mounting machine) of both the work machines in the process of transferring the substrate PB. Since it is possible to adopt a transport mode of the substrate PB in which the substrate PB straddling between the transport conveyors 30) is stopped (standby) in the straddled state, the work position of the work machine (in the above example, the component mounting machine 3 The required time for transporting the board PB to the component mounting position) can be shortened, and as a result, the throughput of mounting production can be improved.

  Here, the detection signal output from one work implement does not pass through the control device provided in the one work implement (and thus the software provided in the work implement), and the control device of another work implement directly adjacent thereto. Therefore, it is difficult to cause a delay (time lag) in the transmission of the detection signal between the work machines, and synchronous control of the transfer conveyor between the work machines can be performed with extremely high accuracy.

  Although the embodiments of the present invention have been described so far, the present invention is not limited to those shown in the above-described embodiments. For example, in the above-described embodiment, the work machine is a component mounting machine and a board loading machine that loads a board into the component mounting machine. Any other working machine (for example, a screen printing machine) may be used as long as it has a substrate detection unit that outputs a corresponding detection signal and a control device that controls the operation of the transfer conveyor based on the detection signal output from the substrate detection unit. Or a reflow furnace, a substrate transfer device provided between adjacent working machines, or the like. In addition, the component mounting line in the above-described embodiment is formed by connecting two work machines. However, this is an example, and the component mounting line of the present invention connects three or more work machines. It may be made up of.

  In addition, the substrate detecting means for outputting a detection signal corresponding to the position of the substrate conveyed by the conveyor is a configuration using light, but is not limited to this, and other configurations (for example, using a limit switch) It may be).

  Substrate transfer mode that enables smooth substrate transfer between adjacent work machines, and stops the board straddling between the transfer conveyors of both work machines in the process of board transfer. Provided is a component mounting line and a board transfer method between work machines.
