Linear drives provide bakery
productivity boost
Two electrical linear drives with ball bearing guidance are used for the vertical movement and control of the lift table.
Riehle Maschinenbau has developed lye application equipment for bakeries, which can be operated by a single person Precision linear drives from Hoerbiger-Origa in the feeding station constitute the core of these systems

Carriers are simply docked and the dough pieces are automatically transported from the feeding station into the lye application machine.
The carts carrying the dough pieces are recognised by initiators in the feeding station and locked in place by Hoerbiger-Origa pneumatic cylinders.
A light barrier checks the position of the dough piece carriers and the operator releases them for transport once the correct alignment has been achieved.
A lift table, driven by two Hoerbiger-Origa electrical linear drives, moves vertically to the upper level of the cart.
For the automatic transfer of the dough pieces, the lift table is extended horizontally by means of two pneumatic linear drives.
The conveyor belt then starts up and takes on the dough pieces from the first carrier.
Once all pieces have been transferred, the pneumatic linear drives retract.
The lift table is then lowered by the electrical linear drives to the transfer position for the lye application machine, the dough pieces are conveyed and the unloading process continues with the next cart level.
At the same time, the lye and optional salt is automatically applied to the dough pieces, which are then deposited onto a baking tray.
The heart of this automated system is the feeding station, which transfers the dough pieces from the carriers to the lye application machine.
Two electrical linear drives with ball bearing guidance are used for the vertical movement and control of the lift table.
Linear drives are suitable for situations where precision and operating speed are paramount.
The linear drives are sealed by a metal strip and have a protection rating of IP54.
This contributes to a long service life, easy cleaning and minimum maintenance in dusty environments The integrated guides of the electrical linear drives minimise the risk of rotation while ensuring smooth operation.
The parallel electrical linear drives for the lift table are synchronised by means of a connecting shaft.
The horizontal movement of the lift table is carried out by two pneumatic, rodless Hoerbiger Origa linear drives.
Despite their small dimensions, these linear drives are powerful enough to bring the lift table with the dough pieces into the correct position quickly.
Since both pneumatic linear drives are fitted in tandem in the lye application machine, no separate guides are necessary.
The rodless, pneumatic linear drives are a suitable attachment point for the lift table. Request a free brochure from Hoerbiger-Origa ...
