  • the relays of the relay chain may be electromagnetic relays or photoelectric relays.
  • the invention relates to arrangements for creating delayed electric control effects in response to the reception of electric impulses.
  • packing machines for example cigarette packing machines in which blocks or packets of cigarettes pass along a feed path from one handling station to another
  • a delay arrangement being provided for causing a signalling or controlling effect after a predetermined delay time.
  • a delay arrangement may be mechanically connected to a shaft of a packing machine so as to rotate therewith, the delay being equal to the time needed for the shaft to rotate through a predetermined angle,'which may be larger than 360.
  • Such delay arrangements have to be built into the packing machine and require additional space which is not always available.
  • the invention consists in an arrangement for creating a 3,579,703. Patented May 25, 1971 delayed electric control effect in response to the reception of an electric impulse, which comprises a relay chain including a plurality of relays connected so that on energization of any of the relays (except for the last relay of the chain) a succeeding relay is prepared for being energized and receives a voltage to energize said succeeding relay when subsequently a switch actuator operates a timing switch, the electric impulse energizing the first delay of said relay chain, and at least one of the succeeding relays having means for creating the control effect when said one relay is energized.

  • FIG. 1 illustrates a delay arrangement of the invention using electromagnetic relays
  • FIG. 2 illustrates a similar arrangement using light sensitive resistors.
  • FIG. 1 comprises a plurality of relays, indicated by capital letters A B C D Z.
  • the contacts of each relay are indicated by corresponding small letters and numerals.
  • relay A has a single contact a1
  • relay B has two contacts b1 and b2
  • relay I has three contacts jl, f2 and i3.
  • a device for synchronizing the operation of the delay arrangement with the operation of a machine to be supervised comprises a cam 1 fixed to a rotatable shaft 2 which may be a shaft of the machine or a shaft geared to a shaft of the machine.
  • a plunger 3 is urged by a spring (not shown) into mechanical contact with the cam 1 and is reciprocatable by the cam 1.
  • An electric switch 4 having two contacts 5 and 6 is urged by a spring (not shown) into mechanical contact with the plunger 3 which operates the switch 4. In the position illustrated, the contact 5 is closed by the switch 4 whereby a terminal 7 is connected to a first conductor '8.
  • a further conductor 11 is connected to a terminal 12.
  • a voltage supply source which, preferably, is a direct current voltage supply source.
  • each of the relays A B C D Z lies a series connection of a resistor 14 and a capacitor 15 so as to render the relays slow opening after de-energization. All the relay contacts of FIG. 1 are initially open.
  • the contact indicated by subscript 1 of each relay has a contact element which is either connected to the conductor 8 or to the conductor 9 so that said contact elements of immediately succeeding relays are connected to different conductors.
  • one contact element of each of the contacts a, cl are connected to the conductor 8 whereas the corresponding contact elements of the contacts b1 and d1 are connected to the conductor 9.
  • One contact element of each of the contacts "1 is connected to one contact element of the contact 2 of the respective immediately succeeding relay, the other contact element of each of the contacts 1 being connected to the other contact element of the contact 2 of the respective immediately succeeding relay.
  • the two contact elements of the contact b1 of relay B are connected to the two contact elements of the contact 02 of the immediately succeeding relay C, each to one.
  • a terminal of each relay is connected to the further conductor 11.
  • the other terminal of relay A is connected to terminal 13.
  • the other terminal of each of the other relays is connected to that contact element of its own contact 2 which is not directly connected to one of the conductors 8 and 9, so that each contact 2 acts as a self-holding contact for the respective relay.
  • Contact b1 of relay B connects relay C through its contact 02 to the conductor 9 and thus prepares an energizing circuit for relay C.
  • the switch 4 on further rotation of the cam 1 closes the contact 6, whereby voltage is applied to the conductor 9 relay C is energized via terminal 7, switch 4, contact 6, conductor 9, contact b1, relay C, conductor 11, terminal 12.
  • the relay C attracts and closes its contacts 01 and 02 before the contacts b1 and b2 are opened owing to the delay caused by the resistor 14 and capacitor 15 of relay B.
  • Contact 02 holds the relay C in a manner similar to that described with reference to contact b2.
  • Relay C thus remains energized after the contacts b1 and b2 have opened.
  • the contact 01 connects the relay D to the conductor '8 so that the relay Dis energised when the switch 4 closes its contact 5 on further rotation of the cam l1.
  • the relays A, B, C, D Z operate successively in dependence on the rhythm in which the switch 4 operates by the cam 1 and plunger 3 closes the contacts 5 and 6 and thereby applies voltage alternately to the conductors 8 and 9.
  • the last relay Z when energized closes through its contact z1 an electric circuit connected to output terminals '16 and 17, said circuit when closed causing a control effect.
  • the control effect is caused by said circuit after a predetermined delay time in response to an impulse applied to the terminals 12 and 13.
  • -It will be recognized that the delay time is dependent on the number of relays of the relay chain and on the speed of rotation of the cam 1. 'It will further be seen that after an impulse has been applied to the terminals 12 and '13, a next impulse may be applied to the terminals 12 and 13 when switch 4 has opened contact 5 and closed again contact 6. The next impulse thus may be applied before the relay Z has responded to the first impulse. Thereby, a number of electric impulses may simultaneously travel through the chain of relays A, B, C, D in successron.
  • FIG. 1 shows a terminal 18 connected to relay 4 D, and an impulse may be fed to the terminals 18 and 12 to directly energize the relay D and causing the succeeding relays to operate in the manner hereinbefore described. Thereby the delay time required for energizing the re lay Z is shortened.
  • FIG. 1 shows the relay I provided with a contact '3 in addition to its contacts '1 and 2.
  • Auxiliary output terminals 19 and 20 for a control circuit are connected to the contact 13. Thereby, the delay time can be shortened.
  • FIG. 2 The arrangement of FIG. 2 is generally similar to that of FIG. 1 except that the relay means do not comprise electromagnetic relays but comprise photoelectric relays.

  • the resistor b3 is illuminated and its resistance is reduced.
  • the lamps have sufiicient heat inertia so that when the switch 104 switches over from contact to 106 resistor a3 remains sufficiently long illuminated by the lamp a2 to maintain the lamp b1 lighted until lamp b2 is lighted and illuminates the resistor b3, and so on.
  • the last lamp z2 is connected to the conductor 111 through a relay V having a contact v for closing a control circuit connected to terminals 116 and 117.
