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.
- 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
