system consists of two counter rotating, on one transport bar mounted transfer
segments. The power transmission of the segments occurs from a servo drive.
Both of the two transfer segments consist of a pneumatic cylinder with a roadbed
and a transfer plate which is in contact with the packs during the sorting operation.
For every sorting operation one of the transfer plates will be deployed pneumatically
and conducts the container during the operation with angular synchronism with
the production speed.
At the same time the second segment (passive) will be set back in basic position,
to reject the next container. This happens for every rejection operation.
During the starting phase of the transfer movement, the weight of the pack is
determined. Afterwards a dead weight depending, progressive acceleration of
the crate is calculated by considering as performance data. This progress brings
out the same transfer width between not filled and filled packs.
After the start signal, the left upper segment is
driven in conveyer speed to the right side, at the same time the pneumatic
controlled transfer movement occurs.
After the container and weight calculation is finished, the calculated acceleration
occurs. At the same time the passive segment, which is below, moves to the
Shortly after the rejection process is finished, the
next rejection can follow with the following segment below.
