2. Various Functions and Outline of Actions
2.1 Various Functions
•
Direct Pickup
The placement heads of the main machine can pick up the components directly
from the pallet which was drawn out from the multi-layer tray feeder. In
addition, the pickup actions can be controlled nely.
•
Elevator/Pallet Drawing Speed Control
By setting parameters for the elevator speed and the transfer speed in the
component library data, it becomes possible to control the speed at which the
elevator should be moved upward or downward and the speed at which the
pallet should be drawn out to or pulled back from the traverse.
Therefore, the posture of the components being supplied can be kept stable.
•
Block
Allocation Function
Up to 9 different pieces of component allocation data can be set for one pallet.
When small trays are handled, additional types of components can be allocated
by installing several trays, increasing the number of components to be used.
Moreover, not only grid-type trays but also staggered-type ones can be handled
regarding them as parallel-bank-arranged ones (overlapped grid type trays),
making it possible to make exible use of trays.
•
Magazine Batch Replacement
By replacing the current magazine with a magazine loaded with the required
components in advance, the replaced magazine makes it possible for
components to be changed collectively and swiftly after the setup operation.
•
Pallet
Alternate Function
The trays having the same type of components can be set on several stages
(pallets) in the spare magazines. Every time the machine gets empty of
components, it automatically selects another spare stage which stores the tray
having the same type of components, making it possible for the machine to
perform the operation continuously.
By providing several stages with a group of components used frequently among
the component types, an interval of component supply can be prolonged.
The order of the pallet alternate actions is based on the ascending order
(advancing from a smaller step No.) of the magazine step Nos.

Magazine Alternate Function
The components required for the production model must be set fully for both
Magazines #1 and #2. When the magazine alternate function is activated, the
machine performs the automatic operation with either one of the upper and
lower magazines being connected. The connected magazine is automatically
changed to the other one set automatically ready for use right after the
connected magazine gets empty of the components, making it possible for the
machine to perform the operation continuously. That is, this function makes
it possible to supply components from the trays while the machine is running,
reducing downtime of the machine for component replenishment.

2.2 Outline of Actions
(1) A pallet is pulled out from the magazine stored in the elevator section onto
the traverse according to the pattern program data.
(2) The placement heads of the main machine pickup components from the
pallet that was pulled out onto the traverse.
(3) The images of the picked components (the components picked up by the
placement heads) are captured and recognized by the component recognition
cameras to detect the deviation in the pickup position.
The detected deviation is corrected and the components are placed accurately
on the specied positions.
When a pickup error or a recognition error is detected during the component
recognition, the machine performs the discharge operation of the rejected
component.
(4) The pallet on the traverse is stored in the magazine of the elevator and the
subsequent pallet is pulled out onto the traverse according to the pattern
program data.
When the subsequently placed component originates from the same pallet,
the pallet stays on the traverse.
(5) Steps (1) through (4) are repeated.
When the tray on the pallet (specied in the pattern program data) becomes
empty of components, the LED of the stage No. button starts ickering and
the error message "Component Shortage Error" appears on the operation
monitor. In this case, reload the tray with components.
