IPC: D05B69/22
Filed: 1969-06-03
Abstract: 1,247,264. Stopping sewing machines. MITSUBISHI DENKI, K.K. 3 June, 1969 [3 June, 1968], No. 28135/69. Heading D1G. [Also in Divisions F2 and G1] A rotary machine (e.g. a sewing machine 10, a riveting machine or fret-saw powered by rotational energy) is connected to a drive (e.g. the shaft of an electric motor 310) having a flywheel 321 by a disk 332 rotatable with the machine and movable between contact with a stationary brake part 341 and contact with the flywheel to transmit rotation from the drive to the machine, a. speed sensor (e.g. tachogenerator 29) on the machine providing signals to an automatic control Fig. 3, for an electro magnet 354 to partially engage the disk and the flywheel so as to drive the machine at a reduced speed, until a predetermined position ,e.g. needle up or down sensed by an insulated gap 23 on a ring 22 mounted on a machine shaft 16) when the electromagnet 354 is switched off and disc 332 is braked against part 341. In the embodiment shown for normal (full speed) operation, the disk 332 is held against the flywheel 321, by depressing a pedal 40 pivoting a bell crank 370 about a pivot 371 to move pins 373 engaging slots in a sleeve 326 carrying the disk. Spring 363 and 377 bias the mechanism to a braked position. The electrical control circuit, Fig. 3, includes the coil of the electromagnet 354 which is energised by rectified a.c. power from a supply 506 when a bi-directional thyristor 509 is energised via a bi-directional diode 513. When the pedal 40 is released a microswitch 380, shown also on Fig. 2, is closed connecting the diode 513 via the ring 22 across the supply 506 (needle up or needle down being selected by a switch 518). The signal from the tachogenerator 29, rectified at 520 is used to control the transistor 525, which, provided the shaft 16, Fig. 1, is rotating above the reduced speed is conductive to the power supply, rectified at 526, thereby preventing a capacitor 514 from charging. Below the reduced speed the diode 513 triggers the thyristor 509 to allow the electromagnet to partially engage the disk 332 and the flywheel 321 until the desired position is reached and the segment 23 breaks the circuit 514, 516, 380, 22, 518, 506. The power switch 504 is controlled by push-buttons 502, 503, Fig. 1, on a control panel 501.
