APPARATUS CONTROL SYSTEM Filed March 23, 1934 2 Sheets-Sheet 2 Patented July 5, 1938 UNITED STATES PATENT OFFICE 2,122,468 APPARATUS CONTROL SYSTEM Application March 23,

11 Claims.

This invention relates to an apparatus control system and more particularly to a system for controlling the distribution in sequence on a coiling device of interconnected coils of measured lengths of strand.

The control system described and claimed herein was primarily designed for the material handling apparatus described and claimed in the copending application of Oscar G. Nelson, Serial No. 717,089, filed March 23, 1934.

An object of the invention is to provide a simple, eiiicient and practical apparatus control system.

In accordance with the object, one embodiment of the invention contemplates the provision of an electrical system, including transfer and interlocking relays, controlled by cams of a counter which is actuated by the advanced strand, for energizing a solenoid in sequence to shift a distributor from one position to another along a coiling head for controlling the distribution of interconnected coils of measured lengths of the strand on the coiling head; the electrical system also including length and interlocking relays controlled by other cams of the counter for energizing a stop relay for stopping the mechanism when a predetermined number of coils have been wound upon the coiling head.

Other objects and advantages will be apparent from the following detailed description taken in conjunction with the accompanying drawings, wherein Fig. 1 is a schematic side elevational view of an apparatus which is to be controlled;

Fig. 2 is a wiring diagram showing schematically portions of the counter which control the circuits;

Fig. 3 is a fragmentary sectional View taken along the line 33 of Fig. 1; 40 Fig. 4 is an enlarged front elevational view of the distributor; and

Fig. 5 is a fragmentary sectional view taken along the line 5-5 of Fig. 4.

Referring now to the drawings, wherein like reference numerals designate similar parts throughout the various views, numeral [0 designates a supply reel (Fig. 1) for supplying strand material II which, when threaded through the apparatus, passes over an idler sheave l2, be- 50 tween rollers 13 and M of a counter l5, through a forked member l6 of a distributor IT, to a coiling head I8 where the forward end of the strand is secured.

The coiling head I8 may be of any suitable construction arranged to receive coils of strand 1934, Serial No. 717,092

material, such as wire, of predetermined interconnected lengths. Inthe present instance the coiling head l8 consists of a drum 20 mounted upon a shaft 2| which is driven continuously by a motor 22 shown in Fig. 2, which motor will 5 be further described hereinafter. Mounted upon the drum 2B are spacing members 23 which are arranged to be moved inwardly beyond the peripheral surface of the drum 2!) by suitable means (not shown), each spacing member having a plurality of equally spaced fingers 24.

The distributor i1 is shown in detail in Figs. 4 and 5 and is mounted for movement upon horizontal supporting bars 28 which are carried by a stationary frame 29. A distributor arm 30 piv-. otally carried at 3| by the distributor I! supports the forked member l6 and is continuously oscillated by a drum cam 32 to which the arm is operatively connected, the drum cam being movable with the distributor I1 and keyed to a continuously rotatable shaft 33.

A rack 35 mounted upon the frame 29 interengages a gear 36 which is keyed to a shaft 31. The shaft 31 is rotated a predetermined distance whenever a solenoid 38 is energized to move its core 39 upwardly, moving with it a pull rod 40 upon which a pawl 4| is mounted to move a toothed wheel 42 clockwise, moving the shaft 31 with the gear 36 in the same direction due to the fact that the toothed wheel is fixed to the shaft. A ratchet wheel 45 is also fixed to the shaft 31 and has teeth positioned to be engaged by a pawl 46 which is actuated by a plunger 41 carried by the pull rod 4!] to limit the rotation of the shaft 31. The rotation of the shaftclockwise rotates the gear 36 in the same direction and due to the connection of the gear 36 with the rack 35v the distributor I! will be moved a predetermined distance to the right, moving with it the distributor arm 30 to another position with respect to the coiling head I8.

When the solenoid 38 is de-energized, the pull rod 40 with the core 39 drops downwardly until a locking pin 50 mounted in the lower end thereof extends into an aperture 5| of a locking plate 52 and'the lower end of the pull rod rests upon the locking plate. When the last coil has been wound, the distributor may be moved to its starting position by manually moving a hand lever 55 to the left (Fig. 4), forcing a pin 56 down- 50 wardly to rock a lever 51 clockwise and to lift the locking pin 50 free of the locking plate 52. A pin 58 carried by the locking pin 56 and extending through an elongated aperture in the pull rod 40 rests upon the lever 51 so that the actuation of the lever will move the locking pin free of its aperture, so that with further pressure upon the hand lever the distributor may be moved into its starting position where the releasing of the hand lever will allow the locking pin 50 to be moved by means of a'spring into the first aperture 5| of the locking plate 52.

Referring now to Fig. 2, which illustrates the control system for the mechanism previously described, there are shown earns 60, 6|, 62 and 63, which are respectively associated with indicating wheels 64, 65, 66 and 61 of the counter I5. The

cams and 62 with their respective indicating wheels are mounted on a shaft I0 and are rotated intermittently counterclockwise one revolution for each 100 revolutions of the roller 14, this roller being rotated by the advancement of the strand I I and completing one revolution for each foot of strand passing between the rollers I3 and I4. The mechanism connecting the wheels 64 and 66 to the roller I4 is not shown since it is of a conventional type. I'he indicating wheels 65 and 61 which carry the cams 6| and 63 are rotated intermittently in a counterclockwise direction through a conventional type of mechanism controlled through the actuation of the wheels 64 and 66 so that the cams 6| and 63 will be rotated one-tenth of a revolution for each revolution of the cams 60 and 62 or one complete revolution for each 10 revolutions of cams 60 and 62. While four indicating wheels have been shown for the purpose of making the illustration more easy to follow, in practice indicating wheels 64 and 66 may be the same element and indicating wheels 7 i when a predetermined length of wire has passed between the counter rolls I3 and I4. For example, let it be assumed that five interconnected coils of wire, each containing 200 feet of wire are to be wound upon the coiling head, totalling 11,000 feet of wire formed into 5 coils.

As shown in Fig. 2 the cam 60 has a high portion positioned to actuate the lever 68 associated therewith at the ninth position of the counter wheel .64 so that when ninety feet ofwire have passed through the counter I5 a break contact will be opened and a make contact 8| will be closed. This action, however, will not complete a circuit until a make contact 82 is closed due to the actuation of the switch control. lever 68 of the cam 6|. The cam BI has four high portions located at positions I, 3, 5 and I on the indicating wheel 65. Therefore, when the cam 60 completes one revolution, the cam 6| will be moved so that the high portion at position I will be moved beneath its lever 68 to move the lever clockwise to close the make contact 82, which remains closed until the high portion of cam 60 at position 9 again actuates its lever 68 to complete a circuit from grounded battery 85 through make contacts 6| and 82, a transfer relay 86 to ground. The energization of the relay 86 completes a locking circuit through a make contact and completes a circuit from grounded battery 85 through a make contact 8'! and through solenoid 38 to ground, thus energizing the solenoid (Figs. 2 and 4) for shifting the distributor I! from one position relative to the coiling head to another position. An armature 88 of a locking relay 89 remains closed until the high portion of the cam 60 is moved beyond its lever 68, allowing the spring 69 thereof to move the rod 15 vertically to complete a circuit from grounded battery 85, through break contact 80, through a make contact 9|, and through the locking relay 89 to ground, thus energizing the locking relay 'tomove its armature 88 free of break contact 92 to open the locking circuit through the relay 86. The solenoid 38 is thus energized after feet of wire have been wound upon one portion of the coiling head, the additional 10 feet being wound upon this portion of the coiling head during the setting into operation of the mechanism for shifting the distributor from one position to another. The distributor will be shifted to the third position when the high point of cam 6| at position 3 is moved beneath its respective lever 68 and when the high portion of the cam 60 is moved for the fourth time beneath its lever 68. The solenoid 38 is, therefore, actuated to shift the distributor after 190, 390, 590, and 790 feet of wire have passed through the counter, but there will be no action to move the distributor at the completion of the 1,000 feet. The lengths of wire on each coil and the total of the five coils, as given, are of course merely illustrative and the counter can be designed to produce coils of any desired length.

The purpose of the cams 62 and 63 is to stop the apparatus when the coils are completed and when the required length of wire has been Wound upon the coiling head. The cam 62 has a single high portion at position 9 upon its indicating wheel 66 for actuating its lever 68 when ninety feet of wire have passed through the counter I5. The cam 62 will, therefore, open break contact I00 to close make contact [ill at each 9 position of the indicating wheel 66, but a circuit will not be completed until the high portion of the cam 63 has been moved beneath its respective lever 68, which occurs when the cam 62 with its indicating Wheel 66 has completed nine revolutions. At the completion of nine revolutions of the cam 62, the high portion of the cam 63 will move its lever 68 clockwise, moving the rod 75 connected therewith downwardly to close a make contact I02, which will remain closed until the indicating wheel 66 again registers 90, positioning the high portion of the cam 62 beneath its respective lever 68 to again close make contact i0I to complete a circuit from grounded battery 85 to make contacts IOI and I02 through a length relay I03 to ground.

The energization of the relay I03 will attract its armatures to complete a locking circuit from grounded battery through a break contact I05, an armature I 05 of a locking relay E06 through a make contact I07 through the relay I03 to ground. The energization of the relay I03 will also complete a circuit from grounded'battery 85, through make contact I08, through a stop relay I09 to ground, resulting in the attraction open break contact IIE].

The additional ten feet of wire is wound upon the coiling'head by the time the coiling head is stopped. Therefore, the counter will be moved to position the cams at their zero or starting position. This will cause the switch controlling levers 68 of the cams 62 and 63 to open the make contacts ill! and IE2, and to close the break contact I09 completing a circuit from grounded battery 85 through break contact I'M, through a make contact i281, and through the locking relay I06 to ground, energizing the locking relay to attract its armature and open the circuit through the relay I03.

' After the winding of the five coils has been completed, they may be removed. from the coiling head and the apparatus conditioned for another operation. The distributor is disposed at the farthest position to the left; and after the forward end of the wire is secured to the coiling head the motor 22 is energized by closing the momentary push switch H2, the break contact II!) being normally closed to energize the relay III, thus closing the motor circuit to energize the motor and thus rotate the coiling head. The counter I5 is immediately set up in operation rotating the was to effectively close circuits to shift the distributor through the energization of the solenoid 38 from one position to another when a predetermined length of the wire has passed through the counter so that 200 feet of Wire will be wound between the fingers 24 of the coiling head at each position without breaking the wire so that at the end of the operation when a circuit is completed through the stop relay I09 by the actuation of the levers 68 associated with the cams 62 and 63, each space upon the coiling head will have a coil of wire totalling 200 feeti making a grand total of 1,000 feet upon the coiling head.
