ABSTRACT:
A test system for testing the quality of electric appliances includes a test line having an endless conveyer which is provided with a multiplicity of carts, a reception terminal for receiving electric appliances from a first assembly line on which the electric appliances were assembled, and an exit terminal for releasing the appliances to a second assembly line after they are tested. The reception and the exit terminals are connected with the assembly lines in response to a run signal instructing the operation of the test line. When the electric appliances are received at the reception terminal, they are each mounted on one of the carts for circulation in intermittent movement in response to the run signal. Located along the endless conveyor are a multiplicity of test stations, which are adapted to carry out required tests when the appliances are transported to the stations. Once a test is done on an electric appliance, the same test will not be repeated on the same electric appliance. The endless conveyor is disconnected from the assembly lines in response to a stop signal instructing the stopping of the test line, so that the conveyor becomes independent of the assembly lines and circulates the electric appliances in the test line. When the test line receives the stop signal, each of the electric appliances are allowed to make a complete circulation through the test line, starting from the position located at the time of reception of the stop signal, to complete pending tests, and then the test line is stopped. The test line may be incorporated in an assembly line, thereby improving the production efficiency of the lines.
