Ill. 60638 Filed Aug. 31, 1964, Ser. No. 393,092 2 Claims. .(Cl. 346-14) This invention relates to a counter-timer-printer device having mechanism to read out counted totals of events such as machine operations during selected time periods occurring successively, the expiration of each time period actuating the printer for a readout tape.

One object of the invention is to provide a device of the kind referred to particularly ,adapted as a production monitor. l

Another object` is to provide a counter-timer-printer which is compact, simple to install, requires only one electricall connectionto plug it into any 110 volt A.C. outlet, which can monitor any one of` any desired number of machines, oran individual machine, for a completely printed record of production per day or any other desired time period, and which can be installed either atv the machine or at a point remote therefrom such as the ofce of a production manager or time study analyst.

Still another object is to provide a unitary device which simplies connection to one or more machines, the production of which are to be monitored, the requirement for each machine being a limit switch or any other type -of pulse generator mounted thereon to pulsate the counter of the device, the -pulse generator responding to any cyclically movable part or the like of the machine.

A-further object is to provide a device of the character referred to which produces a printed record for time study of machines and the like by showing operations per time period and thereby the number of work pieces machined or produced by the machine, for any down time ofthe machine or for times the operator is not on the job and similar situations 'which' result in a change of pace of operations, omission of operations or other events which are desirable of recordation.

Still a` fur'ther object is to provide a readout mechanism having a counter and a printer, a timer being provided which can be preset for counting during predetermined, pre-settable time periods, the printeropera'ting at the expiration of each time period and the timer being automatically reset at the end of each timing period.

An additional object is to provide a cricuit arrangement for a timer having a clutch-actuating coil -operable to reset the timer, the counter and printer having electromagnetic coils foractuating the same and a relay arrangement being provided for the automatic resetting of the timer and proper actuation of -the counter and printer at the times required.

A further additional object is to provide relay actuated means for preventing counting during the time 'that the printer is inoperation but insuring the count as soon as the printing operation is completed. v

With these and other objects in view, our invention consists in the construction, arrangement and combina` tion of the various parts of our counter-timer-printer device, vwhereby the objects above contemplated are attained, as hereinafter more fully set forth, pointed out in our'claims and illustrated in detail on the accompanying drawings, wherein: f

FIG. 10 is a similar electrical diagram showing the positions of the components when a COUNT operation is initiated; and

FIG. l1 is a similar electrical diagram showing the positions of the components when a PRINT operation is initiated. p

On the accompanying drawings we have used the reference numeral 10 to indicate a housing for a countertimer-printer, the timer comprising a unit indicated generally at T and the counter-printer and readout mechanism comprising another unit indicated generally at A. The housing 10 has a hinged section 12 which can be opened for access to the mechanism within the housing and a hinged cover 14 for the exposed portions of the timer and counter-printer and readout mechanism and for a main switch MS and a selector switch SS. A readout tape is shown at 16 issuing from the mechanism A. A hasp 18-20 is provided for a padlock to lock the cover 14 closed when unauthorized admission to the mechanism is undesirable.

Referring to FIG. 5 the timer T comprises a timer motor TM and electro-magnetic coils acting as timer relays and identified T1 and T2. The coil T2 also actuates a clutch as will hereinafter appear. Timer relay switches T11, T12, T13, T21 and T22 are actuated by the respective coils T1 and T2.

Setting and actuating mechanism for the timer T cornprises a setting knob 22 which can be manipulated to set a pointer 23 at selected graduations along a scale 24. The setting knob 22 sets a stop 26 for a traveller 28 which is biased toward the left so that a head on its right-hand end is normally stopped by the stop 26. The timer motor TM has a counterclockwise rotating rotor 30 for driving the traveller 28 in the right-hand direction whenever a clutch roller 32 is engaged therewith by reason of energization of the coil T2. The traveller will thereupon move in a right-hand direction until it engages a latch 34 for releasing the switch T22 as will hereinafter appear. We nd a Microflex reset ti-mer suitable for our purpose as it has a Vernier type dual setting dial arrangement with coarse and ne reading scales 24a and 24b as shown in FIG. l and pointers 23a and 23b readable thereagainst. The dial combination illustrated can be set for time periods as small as nine seconds.

Upward movement of the clutch roller 32 results through a pivoted lever 36 in downward movement of the left-hand end of the switch T22 about a pivot axis such as a shaft 38. The normally open switch T22 is thereupon closed as shown in FIG. 3. The switch T21 is actuated simultaneously with the switch T22 lby both being connected to the shaft 38. Subsequently when the latch 34 is swung toward the right as in FIG. 4, by reason of the traveller 28 timing out, the switch T22 is unlatched and assumes the open position shown in this figure. The switch T21 is also actuated in a similar manner by reason of a similar latch 34a, the latches 34 and 34a being interconnected as shown at 40.

The timer coil T1, when energized, actuates the switches T11 and T12 through an armature 42 as illustrated in FIGS. 5, 6 and 7. As long as the coil is de-energized, the switch T11 is closed and the switch T12 is open as shown in FIG. 5. When the coil is energized, T11 opens as in FIG. 6 before T12 closes. FIG. 7 shows the final position of the vswitches T12 closed and T11 open.

The armature 42 of the coil T1 also actuates the switch T13 which is provided with a pneumatictime delay mechanism such as a piston 44 in a cylinder 46, a check valve 48 being provided to permit rapid movement in the lefthand direction and a needle Valve 50 being provided to Vpermit only slow movement in the vright-hand direction to thereby provide a time delay period for closure of the switch T13 upon de-energization of the coil T1. The needle valve may be adjusted to secure the desired time delay period.

FIG. also shows a main switch MS. It also shows a rectifier R, a selector switch SS and certain associated machine switches M1, M2, etc., in block diagram, FIGS. 8 to 11 showing them in accordance with the necessary electric circuitry, the latter having terminals 65 and 67.

FIG. 5 also shows the counter mechanism and the printer mechanism for readout purposes, the counter mechanism comprising a count coil C for actuating a ratchet wheel 52 to effect rotation of counter dials 54 which in turn rotate type rollers 55 in a well known manner. The printer comprises a print coil P for actuating an anvil 56 to cause a printed impression on the tape l16. Energization of the print coil P also effects tape advance as by means of a ratchet S8 for rotating a drive roller 60, the tape being backed by an idler roller 62. A suitable unit for this purpose is a Sodeco impulse totalizing counter. l

Current supply wires 64 and 66 are shown for supply- `trig a suitable current to operate our counter-timer-printer device such as the usual 110 volt A.C. current. Referring to FIG. 8, the electrical symbol for the rectifier R isillustrated and a caapcitor 68 is shown for smoothing out the pulsating D.C. current. The output supply wires of the rectifier are indicated and in the usual manner.` A manual print switch MP is shown shunting the contacts T11 and the selector switch SS is illustrated as a plurality of contacts 70 to be selectively engaged by a contact blade 72 to select which one of a plurality of machine switches (such as M3 in FIG. 9) is to actuate the the counter-timer-printer device.

When the main switch MS is open as in FIG. 8 (OFF), no current is flowing through any of the circuits and accordingly all tive of the coils shown are de-energized which is indicated by showing them in dotted lines.

To start a monitor operation, the selector switch SS is adjusted to the desired machine such as M3 as shown in FIG. 9 (ON) and the main switch MS is then closed whereupon the first circuit that is established is through the closed contacts T13 and the coil T2 (see FIG. 8), and the rectifier R is energized. The energization of T2 closes the switches T21` and T22 as in FIG. 9, T21 serving `as a holding switch for T2, and T22 serving to energize the timer motor TM and the coil T1. Energization of the coil T1 opens the switch T11 so it is ready to be closed when T1 is later de-energized, and closes the switch T12 Iso as to enable a count operation when one of the machine :switches closes. Energization of the coil T1 also opens the switch T13 for subsequent de-energization of the coil T2 upon opening of the switch T21. The time period for which the timer T is set is now running and any operations that yare counted before a Iprinting operation effect rotation of the counter dials 54.

FIG. (PRINT) shows the operation upon closure of the machine switch M3 which would be installed at machine No. 3. This energizes the count coil C through a circuit from the -jside of the direct current supply through the switch T12 which is closed to enable the count, the selector switch SS, the machine switch M3 and the coil C back tothe side of the circuit. If the machine operates four cycles during the timing period, the counter dials 54 will show this and the print rollers`55, upon the printing operation occurring, will print the numbers showing on the dials. The printing means includes the usual inked ribbon 17 (FIG. 5).

FIG. l1 (PRINT and RECYCLE TIME-R) illustrates the printing operation as Well as the automatic recycling of the timer. When the time period times out, the latches 34 and 341vwill be actuated mechanically by the traveller 28 to open the switches T21 and T22. The opening of T21 de-energizes the coil T2 (since the switch T13 has not yet reclosed because of the time delay indicated TD) and this renders the clutch inoperable by electro-magnetically releasing the clutch roller 32 so that the bias of the traveller- 28 will return the traveller to the stopped position .shown in FIG. 5. This also resets the switches `T21 and T22 as in FIG. 5. Opening o-f the switch T22 de-energizes the timing motor TM and the timer coil T1. De-energization of the coil T1 opens the switch T12 before the switch T11 closes therebyeliminating any possibility of counting while printing inasmuch as a PRINT operation is sometimes coincident with a COUNT operation. De-energization of the coil yT1 also causes reclosing of the switch T13 afterv the time delay period determined by the setting of the pneumatic time-r 44-'46-48-50 has expired which time delay period is sufiicient to permit the traveller 28 to return to stopped position even though the knob 22 is adjusted to the full length of the scale 24. Thereupon re-energization of the coil T2 closes the switches T21 and T22 'and reengages the clutch roller 32 with the traveller 28, the circuit thereupon being re-established for 'restarting the timing period as in FIG. 9. The switches M1, M2, M3, etc., are so designed and so set with respect to the cycling element of the machine which operates them that ythey stay closed long enough to effect a count operation after the print operation recloses the switch T12.

As long as the main switch MS remains closed, the counting will continue (provided, of course, the .selector switch is set to some machine switch, and whether or not that machine is operating), the printer will operate to produce the readout tape 16 and the timer T will recycle. Referring to the tape 16 shown in FIG. 2, for instance, a group a of indicia indicates the printed totals for a machine that had been cycling three times each time period for which the timer was set. Next the operator made a note on the tape that he was selecting machine No. 3 and setting the timer for ten secondv periods at 10:45 on July 30, 1964. He zeroed the counter dials 54, the usual zeroing button 74, FIG. 1 being provided for that purpose, and then started monitoring machine No. 3. Two cycles occurred in the first time period and after that four cycles each time period occurred indicated in the group b. Then for forty seconds no cycles occurred (group c) following which group d indicates four cycles every ten seconds of machine operation.

Thus, we have provided a production monitor device which is particularly adaptable for monitoring a number of machines from a remote central point. For example, estimated production may call for 2,000 pieces per hour or a total of 16,000 pieces per day; but machine operator and tooling have been improved so that the machine can produce 3,000 pieces per hour or 24,000 per day. However, the operator, in lagging through the day, may turn in a production of only 16,500 pieces. Now if the time study analyst monitors the machine and selects a ten minute printed count of 'this machine for a full days production, he would have before Ihim an actual record at the end of the day as to the number of pieces produced per minute. He would also have a record of the number of pieces going into inventory.

Developing this example further, if the rate is 2,000 pieces per hour, the machine would have to produce 33 pieces per minute, or 330 pieces for the iirst ten minutes. Now, let us suppose the operator starts at 8:00 am.; at 8:10 the monitor would print 330 pieces; at 8:30, the monitor would print 990 pieces, and so on, for every ten minutes of the day.

Now let us assume the operator works continuously in the morning; and in the afternoon slows down for some reason. The monitor would indicate such a condition. If the machie is capable of producing 3,000 pieces per hour, the monitor would print 500 pieces for every ten minutes; or ait 12:00 Noon, 10,000 pieces. If at 4:30 p.m., the count is 16,500 pieces, this indicates a let-down in the afternoon.

In checking the printed tape, the time study analyst will be able to tell at what time or times the machine has stopped production because the monitor will reprint the same count number every ten minutes, or will show a letdown in production per minute; that is, less than fifty pieces per minute. An account must be made for the missing 7,500 pieces of production or a little more than two and a half hours of lost time.

Our device is also beneficial to attain maximum tool life or minimum tool breakage. It does a job that no time study analyst could ever accomplish; without it that is, an operators own actual printed record. When used in conjunction with a computer, it can be an mpontant function for immediate stock control. It also has unlimited elds as to recording linear measurement, liquid flow measure, weight, and the like by substituting suitable impulse generators responsive thereto in place of limit switches responsive to cyclical movement of a machine element.

From the foregoing specification it will be obvious that we have provided a counter-timer-printer suitable for production monitoring and capable of producing a visual readout record of permanent character and of considerable use to time study analysis, production managers inventory, clerk-s and the like. Its operation is simple and versatile and permits the individual monitoring of a number of machines by providing a monitoring unit for each, or the monitoring of a number of machines from one monitoring unit having a selector switch for selecting the desired machi-ne to be monitored. The device accomplishes the objects contemplated and obviously certain changes may be made in the construction and arrangement of the parts of our counter-timer-printer without departing from the real spirit and purpose of ou-r invention. It is, accordingly, our invention to cover by our claims any modified forms of structure or use of mechanical equivalents which may reasonably be included within their scope.
