PURPOSE:To suppress the cost by furnishing a sensing switch to sense that any object being transported has passed the sensing point and another sensing switch to sense whether the objct lies in the sensing position, and by allowing the outputs of these switches to serve for informing the operator how the flow condition of the objects is, i.e. stagnating, out of objects or normal. CONSTITUTION:In order to know whether bottles 1 are continuously transported on a line belt 2 or stagnating, or whether there is no bottle at all, a No.1 sending switch 3 is installed to sense that any bottle 1 has passed the sensing point. At the same sensing point No.2 sensing switch 4 is installed to sense whether the bottle 1 lies in the sensing position, and the outputs of these switches are fed into a transport condition judging circuit 5. This circuit 5 is provided with a sensing circuitry 6 for sensing a rise of sensing signal given by said sensing switch 3, sensing circuitries 7, 8 for sensing rise and fall of sensing signal given by the sensing switch 4, a stagnation judging timer 9 and an out-of- object judging timer 10, and the data therefrom shall undergo a logical processing to give information about the objects being stagnating, emptied or in acceptable condition. |
