(5) Parts of the Board Loader System

The CP-643E sequencer loader differs from the “conveyor to conveyor” flow of the

standard sequencer loader. On the CP-643E the flow is on a “receive and transfer” basis

using carriers. As shown in the figure below the board loading system is divided into

three conveyors and two carriers. The direction of board transfer is as follows, from the

in-conveyor, in-carrier, main conveyor, out-carrier, to the out-conveyor. Two boards can

be simultaneously transported on each respective conveyor and carrier (For 2-board

production programs).

In-carrier: Receives boards from the in-conveyor and transfers boards to the main

conveyor.

Out-carrier: Receives boards from the main conveyor and transfers boards to the out-

conveyor.

In the case of a 2-board production program, the second board stops at the middle

stopper position on the in-conveyor thereby creating a gap between it and the first board.

The boards are transferred to the in-carrier and main conveyor in this status.

If the middle stopper position on the in-conveyor is not set correctly this will have a

negative effect on mark acquisition and part placement on the second board.

Direction of board flow →

Cautions:

1. When the main conveyor is to be unclamped, perform the unclamping operation at either

the loading or unloading position. If the XY-table is below the dropped parts tray and the

main conveyor is unclamped, there is a danger of the dropped parts tray interfering with the

clamping jaws.

2: When the in-carrier or out-carrier is advanced or retracted using an I/O operation, the

operation should be carried out with the carrier clamping jaws in the closed status.

1.1.3 Changing the Original Table

The original device table, the table which is used first, is selected automatically when a

new production program or table mode is selected. The conditions under which the

original table will change are listed below.

(1) Change Due to Change of Production Program

The original table is determined according to the table mode when the new production

program is selected. On-screen display content is shown in parentheses.

• Device Change Mode (2A1A) and Changeover Mode (2B1A/2A1B)

The original table changes depending on the setting in the production program as

explained below.

[Program] Machine_data, 37. Original_table (Non, Table1, Table2)

Non: The table other than the table used until now is the original table. If table 1

had been used, table 2 will be the original table, and vice versa.

Table1: When the program has been changed and foreground transmission has been

carried out table 1 will be the original table.

Table2: When the program has been changed and foreground transmission has been

carried out table 2 will be the original table.

When Original_table is specified and many programs have used the same devices, then

time can be saved by not having to change feeder positions, or use commands to change

the original table.

Selected at the Table_Mode section of the “CCIMF Generate” item which displays when

programs are transmitted to the machine.

• Joint Mode (JOINT)

There is no original table.

Edition 1.1 2-1-7 CP643E System Reference

(2) Change Due to Change of Table Mode

• When changing from joint mode to changeover or device change mode, table 1 will

automatically become the original table. If the original table is specified in the

program, that table will be used when changing to device change mode.

• When switching from changeover mode or device change mode to joint mode, there

will be no original table.

• When switching from changeover mode to device change mode, the original table will

remain the same.

Every time the operations described in (1) and (2) above are dealt with, the original table

is changed and it is shown at the display. Press [SET], [STATUS] and [TABLE MODE] to

reach command Page 513/000 to change the original table if the selected original table is

different from the actual table to be used.

1.1.4 Device Tables: Part Pick-up Position and Resupply Position

There are two separate device tables each with 70 for CP-643E (50 for CP-643ME) device

positions. Each table can be resupplied at its respective resupply position.

There are 3 possible table modes that can be set to determine how the device table is to

be used. During operation the device table will move automatically to either its part

pick-up position or to its resupply position depending on the following conditions.

(1) Conditions for Moving to the Part Pick-up Position

The appropriate device table will move to its part pick-up position under any of the

following conditions.

• During production in joint mode, when the device table to be used in the program is at

its resupply position.

• During production in device change mode, when the original table is out of parts and

the spare table is in parts set complete status.

• During production in device change mode, when the original table is changed to the

spare table in the resupply position which is in parts set complete status.

• During production in changeover mode, when the table that has been resupplied is set

as the original table.

• When the device number is specified using [POSITION] commands.
