3.9 Feeder modules
The following feeder modules are currently available to provide the machine with the various com-
ponent types:
3.9.1 Tape feeder modules
– 8 mm SII feeder module
– 3 x 8 mm S feeder module
– 3 x 8 mm S feeder module for 0201/0402 components in paper tape
– 3 x 8 mm S feeder module SL
a
as of 0201 components in paper tape or blister tape
– S feeder module for 12/16 mm, 24/32 mm, 44 mm, 56 mm, 72 mm and 88 mm
– S DP feeder module for deep pockets, 24/32 mm, 44 mm and 56 mm
3.9.2 Other feeder modules
– Linear vibratory feeder, type 3
– Bulk case feeder module
– Surf tape feeder module for 8 mm, 12 mm and 16 mm
– Waffle-pack tray holder
3.9.3 Description
These feeder modules can be used to process all components with the most common package
forms, such as bulk cases, stick magazines and taped components.
The most important feature of the modular component feeding system is its great flexibility. For
example, the conveyor increment can be set on the feeder module. Paper and blister tapes can
be processed with the tape feeder modules. A small range of feeder module types is sufficient to
place a large range of component types.
→ The position detection system on the feeder modules can precisely determine the component
pick-up position. The position detection is carried out automatically whenever the feeder mod-
ule or component trolley is changed.
The feeder modules can be quickly and easily changed or replaced, even by unskilled personnel.
