The Machine >> Functions of Each Part
MEC-CP842-1.0E 3-9
The CP-842ME has an option for pallet tables that can be used to enable batch setting
and removal of feeders.
PCU (Pallet Change Unit)
The PCU is used as a dolly for setting and removal of pallet tables.
3.2.3 Vision System
Parts camera
This CCD camera checks the size and shape of picked up parts.
Mark camera
A mark camera comprises a CCD camera, a light, and a mounting bracket. After the
CCD camera reads the fiducial marks on the panels being produced, the coordinates
are automatically corrected (offset) in accordance with internal calculations.
3.2.4 Panel Conveyance System
Carrier loader
The machine’s sequencer loader conveys panels between the in-conveyor, the XY-table,
and the out-conveyor, by way of panel clamp units (carriers). The in and out-carriers
are both operated by air cylinders in accordance with the placing program.
In-conveyor: Conveys the panel into the machine and transfers it to the in-carrier
by means of the in-lifter.
In-carrier: Transfers the panel from the in-conveyor to the XY-table.
XY-table: Clamps the panel in position and moves it to and from the position for
placement.
Out-carrier: Transfers the panel from the XY-table to the out-conveyor.
Out-conveyor: Conveys the panel to the next machine in the line.
3.2.5 Electrical Control System
Notes Regarding CP-842E/842ME Machine Operation
Absolute encoders are used on all servo motors on the machine.
The wire cable connectors on the servo motors should not be removed. If certain
cables are disconnected, then calibration data will have to be remeasured.
Calibration data measurement is also required at the following times.
•After replacing the motor.
•After disconnecting the encoder cable between the motor and servo amplifier
•If the backup battery in the servo amplifier discharges below a certain voltage
Servo zero setting is not required.

3-10 MEC-CP842-1.0E
Operation panel
The operation panel comprises switches and a touch screen monitor which are used to
operate the machine.
Control box
The control box contains electrical circuit boards used to control the machine. It is
also equipped with a CD ROM drive which is required to install software.
Servo box (Servo BKT)
The servo box contains the servo BKT to which the servo amplifiers and boards are
attached. Users should not interfere with this box, except to perform servo amplifier
replacement.
UPS (Uninterrupted Power Supply Unit)
The UPS unit is positioned in the transformer box at the rear of the machine. Under
normal circumstances, the power supply from the UPS is cut automatically when the
machine is shut down. However, if the machine is not operating correctly, the power
from the UPS unit may not always be cut. As a safety precaution when performing
any kind of electrical maintenance work, always switch the UPS unit off after turning
off the main power switch.
