Definitions

  • the invention relates to a program selection circuit with coin slot machine for self service launderettes, with several programs with different prices.
  • a program selection circuit with coin slot machine for self service launderettes, with several programs with different prices.
  • it is necessary to select a punched card, corresponding to the selected program and to insert the coins corresponding to the charge into the coin slot machine. If the program selection and the amount paid agree, an automatic washing machine is put into operation and the cycle corresponding to the selected program is carried out.
  • this circuit presents considerable progress compared with previously known installations, in which a coin slot machine enabled a certain operating time to be bought and the program had to be set on the washing machine so that a suflicient operating time for the selected program was assured, there was a demand for further simplification of the operation of these washing machines.
  • the program selection circuit in that the coin slot machine is connected with a group of relays, each of which is activated by a certain amount of money, and the contacts of which are connected with each other and also with a group of relays associated with the different programs for controlling the washing machine sothat the insertion of coins corresponding to the price of a program prepares the energizing of the-program relay associated with this particular program.
  • FIG. 1 shows the basic circuit diagram of a program selection circuit
  • FIG. 2 shows the diagramof a coin slot machine located in the circuit of FIG. 1.
  • the program selection circuit of FIG. 1 has five photoresistors PW1, PW3, PWS, PW6 and PW7, forming part of a coin slot machine 50, shown diagrammatically in FIG. 2.
  • the coin slot machine 50 has two parallel channels 51 and 52, into the inlets 53 and 54 of which coins, say, sixpenny pieces and twoashilling'pieces may be inserted.
  • the outlets 55 and 56 of the channels 51 and 52 are closed by a cross-bar 57 serving as a closing member and is actuated by a tension spring 58, holding the bar normally in the position shown, in which the outlets 55 and 56 are closed.
  • the closing member 57 has a magnetic core 59 which may be attracted by a magnetic winding 60 (in the'following, the cash winding), in order to open the closing member 57.
  • the channels 51 and 52 are inclined to the horizontal so that inserted coins roll under their ownweight to the closing member 57 and drop into the outlets 55 and 56 of channels 51 and 52 into a box, not shown, when the cash winding 60 is energized.
  • the photoresistors PW1 to PWS there are five photoresistors PW1 to PWS, and along the outer wall 62 of the channel 52, there are two photoresistors PW6 and PW7.
  • the gap between the photoresistors PW1 to PW is equal to the diameter of a sixpenny piece and that between the photoresistors PW6 and PW7 to that of a twoshilling piece.
  • a light source 65 which il- "ice luminates with closed starting switch ST through holes 66 in the walls 61 to 64 the photoresistors PWll to PW7, unless these are screened by coins inserted into the channels 51 and 52.
  • the photoresistors PWl to PW3 are screened.
  • the photoresistors PW2 and PW4 are not used although they are fitted in the coin slot machine 50 in order to be available for other circuits of the type shown in FIG. 1.
  • the photoresistors PW2 and PW4 may also be omitted or more photoresistors may be provided, for example, along the outer wall 62 of the two-shilling piece channel 52.
  • Each used photoresistor PW1, PW3, PW6 and PW7 is connected with one of five amplifiers V, connected through a supply lead 67 and the starting switch ST with one terminal of an AC. source whose other terminal is earthed.
  • the five amplifiers V form a structural unit 68 and their output terminals are shown in FIG. 1 (from left to right) at 18, 22, 20, 24 and 23.
  • the terminal 18 is connected through a lead a with a relay Ra, and the terminal 22 through a lead b with a relay Rb.
  • the terminals 20 and 2-4 are connected through a lead c with a relay Rc whilst the terminal 23 is connected through a lead d with a relay Rd.
  • the four coin controlled relay-s Ra to Rd are mounted so as to form a structural unit 69.
  • the amplifiers V are so designed that when an associated photoresistor is screened by a coin, the associated relay is energized.
  • the relay Rd is therefore always energized with closed switch ST if at least one sixpenny piece is in the channel 51, whilst for energizing the relay Rb five sixpenny pieces must be in the channel 51.
  • In order to energize the relay R0 at least three sixpenny pieces must be in the channel 51 and at least one two-shilling piece in channel 52.
  • the relay Rd is energized only if I two two-shilling pieces are in the channel 52.
  • the values for energizing are shown by way of explanation (in Swiss currency) for each relay Ra to Rd in the accompanying drawing.
  • the relay Ra has a contact 2 cooperating with a pair of fixed contacts 1 and 3, and resting against contact in the shown position, corresponding to the non-energizing of the relays Ra to Rd.
  • the relay Rd has two contacts 6 and 8, cooperating with two pairs of fixed contacts 5 and 7, and 4 and 9, respectively.
  • the same applied to relay Rc with two contacts 10 and 12 which cooperate with fixed contacts 11 and 15, and 13 and 14, respectively.
  • the relay Rd has one contact 25 and two fixed contacts 16 and 17.
  • the four relays Ra to Rd may all be of the same kind, and the second contacts (not .shown) of relays Ra and Rd and the associated fixed contacts may be disconnected.
  • Conductors e, f, g and h connect always two of the contacts, namely conductor e contacts 17 and 12, conductor 7 contacts 16 and 10, conductor g contacts 13 and 8, and conductor h contacts 15 and 2.
  • relays R1 to R4 forming a structural unit 70, are connected through conductors u, v, w, x, with the fixed contacts of the relays Ra to Rb, namely relay R1 through the conductor v with the contact 3, relay R2 through the conductor x with the contact 9, relay R3 through the conductor w with the contact 4, and relay R4 through the conductor u with the contact 11.
  • the contact 25 of the relay Rd is connected through a lead 71 with the starting switch ST.
  • Four signalling lamps S1 to S4 of different colors are connected in parallel to the relays R1 to R4.
  • the relay R1 is energized if two two-shilling pieces and one sixpeny piece are inserted into the coin slot machine and the starting switch is closed.
  • the fourth coin is ineffective whilst insertion of the fifth coin screens the photoresistor PW5, and on closing the starting switch ST, the relay Rb in the circuit 81-71- 2517-e-1213c-89-x-R2earth is energized, causing the programming relay R2 to respond and the signalling lamp S2 shunted thereto to light up. This indicates to the user that the desired nylon washing program has been selected and continues automatically.
  • the coin slot machine is connected with a group of coin relays having contacts, each of said relays being actuated by a certain am-ount'of money and the contacts of which are connected with eachother and with a group of programming relays associated with the.
  • a program selection circuit for self-service coin slot laundry machines and the like having service programs at different values comprising at least one channel memher for receiving coins inserted in sai d slot, said at least one channel member, being provided with a series of openings spaced apart a distance equal to the diameter of a coin, a'series of photo-electric cells arranged one for each of said openings, a source of electrical energy and a series of coin relaysincluded in said circuit, a series 'of amplifiers" connecting one of said photoelectric cells with one of said relays, said-coin relays being provided with fixed and movable contacts, certain of said movable contacts being-"connected in series with certain fixed contacts of adjacent relays, a series of programming relays for initiating.
