2.2.6 Component changeover tables

A new feeder generation has been developed for the Siplace X. These new feeders also require

a new component table. The new table has no electronic assemblies. The conventional compo-

nent table uses the communication unit for feeder supply and control. The power supply to the

feeders is now non-contacting, run via an inductive interface at the docking unit, directly to the

feeders. The control and communication between the feeder control unit (FCU) and the feeders

is conducted via two optoelectronic channels (fiber optics). The FCU is connected to the machine

control unit via the machine CAN Bus. Both S-tables and X-tables can be used with the machine.

Restriction: If the machine has C&P20 heads, only X-tables may be used.

2.2.6.1 Docking and Undocking

The changeover table (COT) is automatically docked and undocked to/from the machine via 2

pneumatic cylinders. To dock the COT, move the table to the docking unit, close the cover and

press button 5. To undock the COT, open the cover and press button 5.

Edition 09/2005 2 Overview

Each S-table has fifteen slots for 8 mm SIPLACE feeders.

This amounts to a total capacity of 180 tracks for 8mm tapes, if 4 component tables are used.

Each X-table has 40 slots for 8mm X-feeders, amounting to a total capacity of 160 individual

tracks, if 4 component tables are used

2.2.6.2 Adjusting the Changeover Table Height

The COT can be manually adjusted for the following PCB transportation heights.

Adjustment of S-tables and X-tables is identical.

– 830 mm ± 15 mm standard height

– 900 mm ± 15 mm SMEMA height

– 930 mm ± 15 mm SMEMA height

– 950 mm ± 15 mm SMEMA height

2.2.6.3 Overview of X-Feeder

The new generation of X-feeders enables the operator to install feeders on the machines for each

different component type (single track feeder). This ensures optimum exploitation of the machine

locations and optimum preparation of setups for the individual placement procedures.

If errors should occur during production, the X-feeder can be "logged out" and replaced by another

feeder, which is then logged into the system.

A splice sensor can be optimally integrated directly into the feeder.

(1) "Forwards" button

Press briefly to move the tape by the set cycle time.

Press for longer to move the tape forwards. Make sure the cover sheet is not clamped in.

(2) "Backwards" button

Press briefly and release to move the tape backwards by the set cycle time.

Press for longer to move the tape backwards. (Only perform these functions when the cover

sheet is not clamped in)

(3) "Foil" button: press to start the strip removal motor. This runs until the sheet has been

stretched tight and the motor toggle switch turns off or until the timer has counted 30 seconds.

(4) Briefly press the "SET" button to switch over to the next menu in the main operator level

Press for longer to request component verification.
