The example shows the brazing of bushes. In the workstation the workpiece assembly is lifted from the conveyor belt and turned at working speed through 360 . During this time the suction shield is lowered pneumatically to a point close to the emission point. The shield is lifted again before the workpiece assembly is moved on to allow freedom of movement. Depending on the size and weight of the suction extractor device it may be necessary to consider whether an additional linear guide is necessary or whether the lateral forces acting on the piston rod are still within the permissible range. Suitable components Standard cylinder DNC. 5 3-way valve MFH. Rod clevis SG. and mounting attachments Proximity switch SME.

A normal pick-and-place cycle is frequently not able to achieve the desired level of performance. This example shows a solution to this problem in the form of rapid alternate feed from two magazines. This means that the setdown and magazine pick-up operations run simultaneously. The two vertical units used are mounted on a common slide. If very short cycle times are required the .
