Description
United States Patent The invention hereinafter described and claimed has to do with electrical circuits, but more specifically to elec trical interlock circuits for controlling a plurality of operative devices whereby selective operation of said devices may be ellected and in a manner making it impossible to operate more than one at a time.
The primary object of the invention is to provide an electrical circuit such as indicated above, and which is characterized by its simplicity, its reliability, and its eco nomical construction.
In accordance with the above, and first briefly described, the invention comprises circuit means for controlling a plurality of operative devices and having interlock means whereby only one of said devices may be operated at a time, and means for automatically resetting for another operation.
The various features and details or" the circuit of the present invention are hereinafter more fully set forth with reference to the accompanying schematic drawing illustrating the preferred embodiment thereof.
With reference to the drawing it is seen that the circuit may best be described by dividing it into four component circuits, the first of which comprises a plurality of switches lll, only three of which, llt 16A and MB, are shown, and preferably of the single pole, double throw variety, connected in series across a power line 11 having lines A and B for supplying suitable voltage, and in series with a switch 12, contact K3l of switch 13, and the coil of a relay K1. Each of the switches It) is operatively and respectively associated with a solenoid 14, 14A and 143, connected in parallel in the second component circuit and to power line B.
The solenoids are operatively connected by their armatures IE, ISA and 1513 respectively, to devices 16, 16A and 16B, each to be operated upon energization of its associated solenoid. These devices may be any number of different types, or if desired, may be article ejection apparatus such as described in the co-pending application entitled Article Storing and issuing Apparatus, Serial No. 187,636, filed April 16, 1962, in the name of Richard I. Kester, and assigned to the assignee of the subject invention.
Relay K1 includes the normally closed switch 13 in the third of the component circuits, identified by the reference character 20 (at the bottom of the drawing), which also has a relay coil K2 and a start switch 22, all connected in series across a suitable source of voltage indicated at 24. It should be understood that switch 22 in the present illustrated embodiment of the invention is disposed in a position which is inaccessible until switch 12 is closed, as more clearly set forth in the Brewer et al. application identified below. The switch 25 of relay K2 is connected in a DC. circuit 25, the fourth component circuit, having in series, relay contact KZ-ll, relay coil K3 and a capacitor 28. Connected in shunt to contact 312-2 of switch and the line 29 between capacitor 23 and the minus side of; the circuit, is a resistor 3d.
In the operation of the circuit to energize or operate one of the output devices 16, MA or 158, one or" the single pole, double throw switches ltl is moved from its No. 1 to its No. 2 contact, either manually, or in the manner set forth in the co-pending application entitled inventory Control System and Apparatus, Serial No. 162,630, filed December 12, 1961, in the names of Brewer, White and 3,160,793 Patented Dec. 8, 1964 Colburn, and assigned to the assignee of the present in vention. Reference may be had to that application for further details, if desired, although it is not necessary to a complete understanding of the present invention. It is only necessary to know here, that actuation of one of the switches by any means, selects the particular device to be operated.
Normally the circuit is connected to the power source 11 as by closing switch 12, which may be manually operated, or it may be closed by the opening of a door as set forth in the above mentioned Brewer et a1. application, or by some other means, not shown. Closing of switch 12 completes a chcuit from one side A of the line through the switch, and then successively through the series-connected switches lib, MA and NB, contact K34 of switch 13, the coil of relay K1 to the other side B thereof, thus energizing relay R1 to move its switch 18 to open condition against contact Kit-l, as illustrated by the broken line. T he circuit is now in its ready condition for selective operation or" one of the devices 16, 16A or 16B.
Let it be assumed, for purposes of illustration, that it is desired to operate the No. 2 device 16A, in which case the pole of switch lldA is moved from its No. 1 contact, shown in full line, to its No. 2 contact, as shown by the broken line. This opens the circuit through relay K1, dropping it out and returning its associated switch arm (switch 18) from contact Ell-1 to contact (1-2, as shown by the full line, thus readying the circuit for energization by closure of start switch 22;. It is understood, of course, that switch 13 is still in its full line condition (on contact (3-1) and that no power is being fed to the solenoid 14A as yet. Depression of start button 22 will now energize relay K2 to move switch 25 from its KZ-Z contact to its K2-1 contact causing the coil of relay K3 to be momentarily energized by displacement current through capacitor 28.
'Relay K3 will move its switch 13 from contact (3-1 in line B to contact Kit-2 in line A closing the circuit from line A through contact No. 2 of switch 10A and solenoid coil MA to line B, thus to eiiect operation of the device 16A through armature 15A. The surge of dis placement current through DC. circuit 26 will continue until the capacitor 25; charges, approximately .25 second with the values set forth below by way of example. During' the initial surge, the coil 14A is energized, as described above, but when the capacitor reaches full charge, power to relay K3 cuts oil and it will drop out, moving its switch it? bacl: to the full line condition (K3-1 contact) opening the circuit to relay 14A.
in particular accordance with the present invention, it will be understood that only one of switches 10, 10A or Mill can be operative at one time, thus interlocking the circuit by locking out operation of more than one of the devices if, for example, more than one switch is moved to its operative condition (on No. 2 contact), as shown in the drawing, it can be seen that electrical energy can flow only through the switch 10 closest to line switch 13. if switch 1GB is on its No. 2 contact, current cannot flow through this swit h to switch WA, or any of the others to the left of switch MB.
Thus, it is obvious that only one of the devices 10 can be operated at a time and that a second article cannot be issued until completion of a cycle of operation and re setting of the circuit, as described below.
Referring to DC. circuit 26, it will be understood when capacitor 23 is fully charged that current to relay K3 is cut oil causing it to drop out, and if at this time the start button has been released (opened) the circuit will reset to its normal condition ready for selection of another, or even the same switch Ill.
In the drawing, it wil be noted that the operative devices 16 are numbered No.' l, No. 2 and No. X to indicate that any number of devices may be connected in the series,-
the circuit lines being indicated as broken between switches and 10A for this purpose.
The resistor 30, in shunt around relay coil K3 and capacitor 28, from switch 25 to the negative side of the line in circuit 26, is effective when the switch is in the full line condition shown, to discharge the capacitor 28 to ready the circuit for a subsequent operation. From the above, it is seen that start button 22 must be released before a second selection can be made, thus effecting a built-in reset feature in the circuit.
By way of example, the relay K3 may have a value of 10,000 ohms, the resistor a similar value, the capacitor a value of 12 t, and all of the circuits may be supplied with 115 volts.
From the above, it is now clear that the invention provides an electric circuit having all of the characteristics and advantages set forth above.
