Filed: 1993-12-08
Abstract: PURPOSE:To enable surely detecting incompleteness of capping by providing to a pressing plate succeeding a provisional fitting part a sensor which detects by means of an electrical signal the physical quantity of any rise over a set height in a normal state. CONSTITUTION:A cap 9 fed in a properly oriented state from a hopper 22 is held in a slanting state by grippers 24. On the other hand, a bottle 8, as it is brought horizontally with the body set upright, inserts the rim of its mouth into the cap 9 and, as the bottle advances further, the cap 9 comes off the grippers 24 and gets fitted deeply over the rim. Next a detector 21 pushes downward a pressing plate 26, extending horizontally from a frame 25, and allows it to move up and down. The pressing plate 26 is so designed that it leaves a slight gap over the cap 9 when the bottle is capped normally. When a strained cap 9 is put on the mouth of the bottle, the pressing plate 26 rebounds to a greater degree and the up-and-down movement causes a lever 31 to come into contact with the pressing plate 26; thereupon a sensor 30 indicates the abnormality by means of an electrical output signal or acts to stop the bottle from movement.

IPC: G11B21/08
Filed: 1989-12-27
Abstract: PURPOSE:To input two phase positional signals alone thereby to detect the absolute position by forming a binary number representing information of the direction and quantity of the positional displacement. CONSTITUTION:Two phase positional signals POS-A, POS-B have the phase difference of 90 deg. from each other. A first means of this position detecting apparatus generates a pulse signal which inverts the polarity at every positional displacement corresponding to a quarter of the period of the phase positional signals. A second means generates a pulse signal which inverts the polarity at every positional displacement corresponding to a half of the period of the phase positional signals. Moreover, a third means generates a first pulse signal at every positional displacement in one direction corresponding to one period, and a fourth means generates a second pulse signal at every positional displacement in the other direction corresponding to one period. A counting means uses the first and second pulse signals as an addition signal and a reduction signal. Accordingly, the absolute position of an object can be detected by using a binary number having the binary output signal obtained by the first means as the least significant bit, binary output signal obtained by the second means as the second least significant bit and binary output signal obtained by the counting means as the significant bit.
