① PCB Transfer Mode

Two kinds of PCB transfer modes are available as shown below.

Transfer mode PCB load timing

Normal transfer After a component-mounted PCB passes the conveyor exit sensor

Anticipate transfer After a component-mounted PCB passes the board arrival sensor

② Checking the conveyor configuration

Menu: System>SystemParameter>MachineConfig.2

You can check the conveyor configuration.

③ Setting the PCB transfer conditions

Change the transfer mode. Additionally, set a period of time for each item to adjust the transfer

timing.

Check the conveyor

configuration.

(You cannot change the data.)

When [Loading next board after passed

arrival sensor] is checked on, the

transfer mode enters the anticipate

transfer mode.

When this check box is checked off, the

transfer mode enters the normal

transfer mode.

Next, set a period of time for each item.

Adjust the conveyor deceleration start

timing in the [Slow Down Sensor ->

Start Deceleration] area.

Adjust the conveyor stop timing in the

[PCB Sensor ON -> Stop] area.

If the PCB does not reach the stopper,

increase the time.

④ Detailed description of transfer mode

 Normal transfer mode

If [Loading next board after passed arrival sensor] is not checked on, the normal transfer mode

will be activated.

The next board is loaded at the timings shown in the table below. For the normal transfer mode,

only the “Transfer time after PCB passed the exit sensor” timing setting is effective and other

timing settings will not be effective.

Conveyor configuration Board loading timing

Main After a component-mounted PCB has passed the exit sensor and then it has

been transferred only for a period of time set in [Transfer time after PCB

passed the exit sensor], the PCB stopper will be turned ON and the next

PCB will be loaded from the previous process.

Entrance & Main

(with entrance buffer)

After a component-mounted PCB has passed the exit sensor and then it has

been transferred only for a period of time set in [Transfer time after PCB

passed the exit sensor], the PCB stopper will be turned ON and the next

PCB will be loaded from the entrance buffer.

Main & Exit

(with exit buffer)

When a component-mounted PCB makes the exit buffer sensor turns on, the

PCB stopper will be turned ON and the next PCB will be loaded from the

previous process.

If the request signal is received from the next process when a

component-mounted PCB waits on the main conveyor and exit buffer, the

component-mounted PCB on the exit conveyor passes the exit sensor, and

then it is transferred only for a period of time set in [Transfer time after PCB

passed the exit sensor]. After that, the component-mounted PCB on the

main conveyor is unloaded to the exit buffer.

Entrance & Main & Exit

(with entrance buffer &

exit buffer)

When a component-mounted PCB makes the exit buffer sensor turns on, the

PCB stopper will be turned ON and the next PCB will be loaded from the

entrance buffer.

If the request signal is received from the next process when a

component-mounted PCB waits on the main conveyor and exit buffer, the

component-mounted PCB on the exit conveyor passes the exit sensor, and

then it is transferred only for a period of time set in [Transfer time after PCB

passed the exit sensor]. After that, the component-mounted PCB on the

main conveyor is unloaded to the exit buffer.

 Anticipate transfer mode

If [Loading next board after passed arrival sensor] is checked on, the anticipate transfer mode will

be activated and the transfer time will be shortend.

As the “Transfer time after PCB passed the arrival sensor” is changed, the transfer time can be

shortened. However, be sure to enter a numeric value exceeding 100 ms. If you enter a value that is

100 ms or less, the value you have entered is returned to the default value. If this time is too short,

the stopper may turn ON immediately after the arrival sensor has been turned OFF, causing the

PCB to be pushed up. In addition, please note that “Transfer time after PCB passed the arrival

sensor” is the time originating from when the sensor is turned OFF in the case of boards with

holes.
