Abstract

PURPOSE:To secure center detection by counting pulses while allowing a one- way travelling body to pass through the first and second sensors issuing the pulses in the period ratio of 1:2, and outputting a center detection signal when counted values agree with each other. CONSTITUTION:While a panel 12 carried on a roller conveyor 11 in the right direction passes through the first sensor 16 to allow a pass detection signal to be outputted, the first counter circuit 27 counts constant period pulses P1 to input them into a comparator circuit 30. Successively, the panel 12 passes through the second sensor 17, and a pass detection signal is inputted into the second counting circuit 28. The second counter circuit 28 counts pulses having its period P2 two times larger than that in the first counter circuit 27 and inputs them into the comparator circuit 30. When the first and second counting agree with each other, the comparator circuit 30 outputs the center detection signal of a panel 12. Hereby, it is possible to precisely detect the center of an article to be carried.

- [Background of the sounding technique IIF] -4, the pigeon coop that unloads the object being transported must match the center of the object with respect to the transport distance -14. In some cathode ray tube manufacturing plants, the sealing surface of the panel is cleaned before sealing the panel and the 7-channel. In this cleaning, the panels are moved onto a roller conveyor so that the seals are facing downward, and acid or pure water is supplied from below. Need to unload. Conventionally, this unloading was done manually, but there was a problem in that friction occurred between the sealing surface of the pigeon coop and the panel sealing surface and its roller, resulting in dirt on the sealing box. In order to solve this problem, it is considered that the unloading of the panel is automatically carried out using a special machine, but for this purpose, the K is required to accurately detect when the center of the panel in the transport direction has moved to the unloading position. is important.

[The second aspect of the invention is to detect the conveyance direction ec*sui center of an object being conveyed in a direction, which is installed in the conveyance path of the object so that the front edge of the object passes through. A sensor 4 generates a passage detection signal from 1 until the rear end passes, and a count circuit 1 counts pulses at a constant period while a passage detection signal is generated from the sensor 1. , which is installed downstream of the sensor of the conveyance path, generates a passage detection signal as the front end of the object passes, and the passage detection signal 4# from the sensor of the body 2 and the sensor of the body 2 generate the passage detection signal of the body 1. Compare the count path of 2, which counts pulses set to twice the period of the count pulse of the count circuit, with the count number of the count (2) path of these 1 and 2, and calculate the number of counts for both. A center detection device integrated with conveyance is characterized in that it is equipped with a comparison circuit that generates a center detection signal when the objects coincide with each other, and accurately detects the center of an object being conveyed in the conveyance direction, regardless of the size of the object. .
