Definitions

  • ABSTRACT A tripping mechanism for a power unit for the drive of time related rotating contactors requiring a powerful torque for their drive. A drive motor is triggered periodically, thus driving the contactor.
  • FIG. 1 is a profile of the tripping mechanism
  • FIG. 2 is a plan view of the entire mechanism
  • FIG 3 is a front view, and partially a sectional view, to demonstrate the dependent operation
  • FIGS. 4 and 5 are plan views of the control and cam disc to demonstrate the turning on and turning off the motor
  • FIG. 6 is a partial view of another species for the turning on and turning ofi arrangement for the motor
  • FIG. 7 is a plan view of the above arrangement.
  • FIG. 8 is a signal disc which is connected with a clutch plate.
  • the shaft 18 of the'electromotor 2 is connected to the drive shaft 1 through the gear wheels 3 and 4.
  • the drive shaft 1 continuously engages a contactor (not shown) which requires a powerful torque for its drive.
  • the drive shaft 1 is rigidly connected with a control disc 6 which is provided with a pin 19.
  • One end of a drive spring 7' is hooked at this pin 19, and the other end of said spring is connected to clutch plate 8 by way of .pin20.
  • the cam disc 12 carries a tappet 21.
  • the control disc 6 is provided with at least one recess 22 (FIGS. 4 and 5) and the cam disc 12 with at least one cam 23.
  • FIG. 4 depicts the relative positions of the control disc 6 and the cam disc 12 upon completion of a winding operation.
  • trigger peak 24 has engaged the recess 22 of the control disc 6 and cam 23 0f cam disc 12 has just left the recess 22.
  • pin 20 of the clutch plate 8 will move so as to abut pin 21 of the cam disc 12.
  • cam disc 12 will be carried along in the direction of the arrow by the pins 20 and 21. This will continue until cam 23 reaches the area of recess 22, as shown by FIG. 5.
  • trigger peak 24 of switch 5 will be raised and switch 5 (FIG. 2) will be closed.
  • FIG. 5 depicts the position just before the closing of switch 5. As soon as switch 5 closes due to the raising of trigger peak 24, current fiows through the motor 2, causing the drive shaft 1 to turn. Control disc 6 and pin 19 will then turn together with the drive shaft 1. As a result, control disc 6 and pin 19 will rotate by 180, thus again tightening the spring 7.
  • pin 19 reaches the wall 25 of the notch 26 of cam disc 12 and carries disc 12 along until cam 23 has left the reach of trigger peak 24. At the end of the winding cycle, pin 19 will be located opposite to the position shown by FIG. 5, that is, turned by 180.
  • recess 22' is now at the left side, in other words it is engaged by the trigger peak 24.
  • the cam 23' is located beyond said recess 22' so that it is now in the same position as cam 23 in FIG. 4.
  • pin 20 will reach and fit snugly to pin 21 due to the rotation of the clutch plate 8, either in functional relation to the cycle of the time-keeping vibrating system or the control by the master timer impulses, thus causing the cam disc 12 to turn.
  • Cam 23 reaches the area of recess 22 now located at the left side thus causing the closing of contact 5.
  • the control disc 6 will again turn by I80", and at the end of this turn, the pin 19 will again carry the cam 23 from the area of the recess 22, now located at the left side.
  • the position reached at the end of this winding movement is I depicted by FIG. 4.
  • the activation of switch 5, supplying current to the motor is accomplished in functional relation to the position of the cam disc 12 which is being moved by the clutch plate 8.
  • the switch 5 is cut ofi' in functional relation to the position of the control disc 6, dependent on the rotation of the motor 2.
  • a spring 27 is placed between pins 20 and 21, and this spring is tightened at the end of the winding movement when the cam disc 12 is carried along by the pin 19, with pin 21 moving away from pin 20.
  • FIGS. 6 and -7 show a modification of the control of switch I 5.
  • a control disc 6 is employed which is not rigidly connected to the motor shaft 1.
  • the connection between this control disc 6 and the motor shaft 1 is accomplished by means of a coupling part 27 which interacts with a pin 28 of the control disc 6.
  • the drive shaft 1 is also provided with a coupling part 29, at which is fastened one end of the drive spring 7, its other end being connected to pin 20 of the clutch plate 8.
  • the control disc 6' is provided with a tappet 30.
  • FIG. 7 depicts a position where the trigger peak 24 of the switch 5 has engaged the recess 22 of the control disc 6.
  • the motor 2 is without current.
  • the turning of the clutch plate 8 takes place either slowly in phase with the oscillations of a mechanical vibrating system 11 or periodically through release of a master timer impulse.
  • the clutch plate 8 is connected through the intermediate gear wheels 9 and 10 with a retard of a vibrating system 1 1.
  • the vibrating system 11 is driven by the spring 7.
  • the vibration rate and the gear ratio are selected in such manner that the clutch plate 8 will perform half a revolution per minute.
  • the motor 2 is supplied with current every minute and will rotate until the drive shaft 1 has completed a 180 turn. Therefore, the winding interval amounts to one minute, and each minute the drive shaft 1 will perfonn a transitory turn by I80.
  • the intermediate gear wheel 9 is moved to the right by way of the control lever 17 until pin 31 reaches the area of the locking fork 14 (see FIG. 3).
  • This locking fork 14 is connected to the armature 32 of a relay 13 which is energized by polarized master timer impulses.
  • the arm 33 is located within the area of pin 31 of the intermediate gear wheel 9.
  • the armature 32 with the locking fork 14 will swivel upward and the arm 33 will thus release the pin 31. Since the force of the drive spring 7 acts upon the clutch plate 8, the pin 31 will turn in direction of the arrow until it hits the arm34 of the locking fork 14, the arm 34 now being within range of pin 31.
  • the clutch plate has now carried out half a turn, and this turn by 180 causes motor 2 to be turned on until the drive shaft has carried out a 180 turn. Therefore, the control is identical with the control as described on the basis of FIGS. 4 and 5.
  • the relay 13 receives another master timer impulse, again causing the clutch plate to turn by 180.
  • the contactor itself can serve as master timer and furnish periodically impulses of a specific duration.
  • the clutch plate 8 is pro vided with two recesses (see FIG. 8) to be engaged by the trigger peak 35 of a switch 16. The switch 16 is closed until the trigger peak 35 enters either one of the recesses 15. In this manner, an impulse of a specific duration is delivered every minute.
  • a tripping mechanism for a power unit to drive time-related, rotating contactors which require a powerful torque for their drive comprising in combination,
  • control disc being effective in response to rotation by said motor shaft to control said switch means to de-energize said motor
  • control disc is provided with at least one recess
  • said apparatus further including a cam disc having at least one cam surface and being mounted for rotation coaxially with said control disc, I
  • control disc is provided with two diarnmetrically opposed recesses and said cam disc has two diametrically opposed cam surfaces, said arcurate slot extending over an angle not exceeding 6.
  • control is rotated by said clutch plate to an extent to move said recess past said responsive means.
  • said apparatus further including a relay for engaging said locking fork
  • said relay being responsive to periodic electrical impulses.
  • the apparatus of claim 1 which includes an axially movable clutch wheel, a vibratory means, and a locking fork, said clutch wheel in one axial position engaging said vibratory system and in its other axial position engaging said locking fork.
