The StoreX 40 Handler
Inside the StoreX climate chamber there is a handling system that allows random
transport of plates. Plates can be moved internally as well as transferred to and
from the environment. Access times are short and the internal climate is kept
stable even for short time periods between accesses.
A Handler (4) is used for vertical transport as well as loading and unloading of
samples. The Handler consists of a Vertical Positioning Drive (40), a Turn Drive
(42) and a Shovel Drive (43). The Handler has a number of vertical positions
which are determined by the number of stacker levels and the loading or
unloading level.
A Stepper motor is used for vertical positioning of the Handler. All vertical
positions are defined by a z-Initiator (15) and the software z-Offset (DM20). The
level height is determined by the number of steps of height. The actual travel
path to a certain stacker level is calculated by multiplying the level (DM5) by the
pitch (DM21) and then adding the z-Offset (DM20). The z-positions of the
Transfer Station are stored in Data Memories (DM22, DM24).
The Handler is not only used for vertical transport of the samples, it is also used
to pick and place plates in the stackers and to get from, or put plates on the
Transfer Station. The pick / place and get / put actions are vertical movements
with the extended shovel. Beware of the difference in vertical travel for pick /
place movement (DM21), get movement (DM26) and put movement (DM28).
The Turn Drive is used to face the Shovel towards the Transfer Station or
towards the desired stacker. The Turn Drive may be positioned at three turn
positions. The position at the left stacker is stored in Data Memory DM80, the
turn position at the right in Data Memory DM81 and the turn position at the
Transfer Station is stored in Data Memory DM82.
The radial Shovel motion is between two hard stops. Force and speed of this
drive is controlled by the hardware of the controller card. Speed and force can be
adjusted by authorized service personnel.
