Workpiece data                                                                                              

Workpiece: Cylinder block for 3 and 4 cylinder motors

Dimensions: approx. 360x340x270 mm

Piece weight: 14kg – 17kg

Cycle time: 30 seconds/workpiece



Automatic packing of the raw parts from pallets to the conveyor system.

  • The raw parts are brought in several layers onto the palettes in free container parking places.
  • There are several parking places available. A parking place is used for storing the intermediate layers.
  • For each type preselection it is established by the production which raw part type will be processed next.
  • The robot is movable on a linear axis, so that all the parking places can be reached.
  • The gripping system of the robot is equipped with the appropriate camera and illumination system.  Through this a reliable component detection is guaranteed with the pick up from the pallet.
  • After a layer of cylinder blocks is completely stacked a gripper change is done, so that the intermediate layers are picked up and can be securely placed down.


Automatic screwing of RFID data carriers in the cylinder block

  • The cylinder block is placed by the robot on a swivel device, which makes the workpiece available for the pick up of a RFID data carriers through a second robot with a screwdriver.
  • The cylinder block is placed on the friction roller conveyor and is ready for processing.
  • The second robot takes the RFID data carrier from a blister and deletes the saved data before this is screwed in the cylinder block.
  • The blister fitted with RFIC data carriers are made available in a drawer changing       system.

Linking of the work sequences

  • The cylinder blocks get to further processing on a friction roller conveyor linked with rotary tables and lift traverse units to the respective next processing machine.
  • Pneumatic stoppers are used for separating the workpieces.
  • In order to document the required production data, there is an integrated RFID writing/reading head integrated on each work sequence.

Uncoupling modules

  • Round storage towers are used in order to uncouple the individual production processes.
  • Each round storage tower has a holding capacity of 90 cylinder blocks.
  • The storage places are arranged on 9 levels. The storage and retrieval is done according to the FIFO principle.
  • Charging the storage places is done with a stacker crane, that moves in the vertical axis and can rotate horizontally.

Manual end control of the cylinder blocks

  • On our test and control area the workpieces are stopped pneumatically and fixed in order to execute a visual check around it. This can be turned in two axes.
  • While NOK components are ejected, the OK components end up in a laser station.

Automatic describing of the cylinder blocks with a data matrix code

  • The saved information of the RFID data carrier is read out in a laser station and written using a
  • signing laser as data matrix code on the workpiece. The legibility of the DMC is checked with a camera system.

Automatic unscrewing of the RFID data carrier from the cylinder block

  • After applying the DMC, the RFID data carrier is automatically screwed on to the OK components.
  • These land in a waiting small load carrier and can be used again.
  • The finish processed workpiece is transported further to its pick up position.

Manual packing of the finished parts from the conveyor system on pallets.

  • For each overhead crane system with load handling equipment (=LAM) the workpieces are manually loaded on pallets.
  • An intermediate layer is put down with the aid of vacuum grippers on the LAM
