Abstract
In a process for checking and/or adjustment and/or assembly of valves, in particular electronically controlled injection valves for internal combustion engines, in which the valves are conveyed along a test line having successive test stands, a test line that is fully automatic and thus free from disturbing effects of manual or semi-manual operation, with optimized flow of material and objective measurement or test results, can be obtained by coordinating computer-controlled transport systems with one another and with computer-controlled test stands by use of a higher-level control.
Claims12
A process for testing and adjusting valves, especially electronically controlled injection valves for internal combustion engines, wherein the valves arranged in pallets are conveyed by means of a transportation system through a test line consisting of consecutive computer monitored and computer controlled test stands, characterized in that the process comprises the steps:
- 1. supplying the test stands of a first test block with a pallet carrying the valves by means of a first computer controlled linear portal transportation system, which can be coordinated by an overriding control with the test stand as well as with at least an additional computer controlled linear portal transportation system;
- 2.
A device for testing and adjusting valves, especially electronically controlled injection valves for internal combustion engines, said device having a transportation system which conveys the valves arranged in pallets through a test line consisting of successive computer monitored and computer controlled test stands, characterized in that said device includes a first test block A comprising a first linear portal with a computer controlled articulated arm roboter for a run-in test of the valves, extending, transversely to a transportation direction of a pallet feeding device, between test stands aligned opposite each other, said device further including a second test block B and an intermediate storage in a transition region between the first test block A and the second test block B, the second test block B comprising a second linear portal with computer controlled articulated arm roboter, said second linear portal extending in the transportation direction of the pallet feeding device, transversely to the first linear portal, and test cells each having at least two test stands arranged in an operative region of the second linear portal, an articulated arm roboter being integrated into each test cell, said device also comprising a conveyor for conveying said pallets away from the test stand, wherein said first linear portal is coordinated by an overriding control with the test stands in said first test block A, as well as with said second linear portal in said second block B.
