23 Claims.
The present invention relates to coil forming machines, and more particularly to such machines wherein the operations thereof are automatically controlled.
Among the objects of the present invention is to provide a novel coil forming machine adapted to successively and continuously form coils of the desired length and wherein the various op.- erations for forming such coils are automatically controlled.
'I'he present invention comprehends the idea of providing control means in a coil forming machine for successively and continuously forming desired lengths of coil Without manual manipulation.
Another object within the purview of the present invention is to provide a novel control circuit having means therein for controlling the 'feeding of the wire forming the coils, the cutting or severing of the coils as formed, and the operation of the coil receiving means for discharging the same from the machine. The invention also includes as an obj ect the idea of providing one or more of these control means, such control means operating independently or in combination with one another.
A kstill further object of the present invention is to provide in a control circuit for the coil forming machine suitable means whereby the cutting means for the coil is operated only after a predetermined time has elapsed after the feeding means for the wire has become inoperative.
Other objects, features, capabilities and. advantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.

Figure 6 is a diagrammatic showing of a control circuit as embodied in the coil forming machine shown in Figure lof the drawings.
Referring now more in detail to the drawings, a coil forming machine generally designated as 2 corresponds essentially in the general construction thereof to the coil forming machine disclosed in the 'Olgay Patent No. 2,089,036, granted August 3rd, 1937, such machine comprising a base Il, having upstanding walls 6 and 8 for supporting a gear train, generally represented as I0 and operated by means of a pulley I2 from any desired source of power. `Operated by the gear train I0 are opposite pairs of wire gripping rolls I2 and I4 and I6 and I8, these rolls gripping the wire 20 as the same is fed through guides 22, 24 and 26 for feeding the same to coil forming means 28. This coil vforming means comprises a spindle 30 about which the wire is coiled by means of the angularly disposed abutments 32 and 34 which may be adjusted as by means of the thumb screws 36 and 38, respectively. 'Ihe pitch for the coil formed on the spindle 30 is controlled by the pitch control member 40 pivotally mounted on the front wall 6 of the base as at 42 and. adjusted by means of the mechanism 44, all as clearly disclosed in said Patent No. 2,089,036.
The present invention is directed particularly to control mechanism for the coil forming machine as described above, although it is to be understood that the control mechanism may be used in other coil forming machines if desired. Such control mechanism includes means whereby the machine will automatically operate continuously to form desired lengths of coil, to cut the same into such desired lengths and to dis;- charge these cut lengths of coil from the ma.- chine without manual manipulation.
In order to eiect these results, the mounting for the upper wire gripping rolls I4 and I8 includes the movable wall section 46 which is engaged by a roller 48 mounted upon a lever 50, one end of which is pivotally connected as at 52 to the opposite walls 6 and 8 of the machine and the other end of which is connected by a rod 54 to the movable cor-e of the solenoid 56 which is mounted for convenience on plate 58 attached to the machine in any desired manner. Upon energizing of the solenoid 56, the outer end of lever is moved downwardly to apply pressure through the roll 48 to the wall section 46 whereby rolls i4 and I8 are moved into gripping engagement with the wire 20 to feed the same onto the spindle 30. The control circuit for the solenoid 56 Will be hereinafter set forth in detail.
Disposed in front of the wall '6 of the coil forming machine is a coil receiving means 60 which is positioned to receive the coil 62 as the same is formed on the spindle 30. This coil receiving means comprises a frame member 69 to which is secured a bracket 65, this frame member being pivotally mounted as at 1 to the base 4 whereby the coil receiving means may be swung to the right, as viewed in Figure 1 of the drawings, whenever it is desired to inspect the spindle 86 or any other element in the immediate vicinity thereof. vided with an elongated abutment 64 disposed at an angle to the vertical and forming, with a corresponding member 66, a substantially V-shaped trough for receiving the coil as the same is formedon the spindle 30. 'I'he members 64 and 66 are mounted in association with one another as described by means of the springs or flexible straps 68 and 10. These straps 68 and 10 are secured to the frame member 69 and thus provide a substantially rigid mounting for abutment member 64 permitting downward movement of member 66 in respect to member 64 and into the dotted line position as represented at 12 in Figure 4 of the drawings. This movement takes place about rod or shaft 14, to which member 66 is connected by the ears 16 and 18, through the lever 86 which is operated by the link 82 having one of its ends connected to the lever 86 and its other end connected to the movable core 84 of the solenoid 86. The operation `and control of this solenoid 86 for moving the member 66 will be set forth hereinafter more in detail.
It will be noted that movement of member 66 into its dotted line position as shown in Figure 4 ci the drawings provides an opening between members 66 and 64 permitting the discharge of the coil 62 from the trough formed by these members. In order to assure the proper discharge of the coil 62, one or more members such as 88 may be connected to the shaft or rod 14 and adjusted in such a position that upon movement of member 66 this member 88 will contact the coil and dislodge the same if Ycaught for its properv discharge from the trough.
The operation of the control circuit, whichis to be described hereinafter, is initiated by a switch 90 adjustably mounted upon a rod 92 as at 94, the rod 92 being secured to the bracket 65 in substantially parallel relation with the rod 14. This switch member comprises the contact 86 which is grounded in relation to the machine, and a spring contact 88 which is disposed in the control circuit by lead |00, this spring contact 98 being disposed in the path of the coil 62. As the coil 62 approaches the desired length, it engages and presses against the spring contact member 9S to raise the Ysame into contacting relation with contact 96, closing the control circuit for initiating certain operations.
The present invention also comprehends suitable means for cutting the coil after it has been formed to the desired length. Such means includes a lever |02 pivotally mounted as at |64 cn the front face of the wall 6 and having a cutting blade |66 mounted adjacent one end thereof,
1e other end being connected through the rod mechanism |68 to the movable core ||0 of the solenoid ||2Valso mounted conveniently in any desired manner atthe front of the coiling machine, this solenoid being in the control circuit for operating the lever |02 in its proper sequence of operations. Upon upward movement of the lever |02, theend adjacent the solenoid ||2 through the lug ||4 contacts` the crank arm ||6 The coil receiving means is further pro-y of a switch ||8, which switch, as will be hereinafter more fully disclosed, completes a circuit for lthe operation of the solenoid 86. In order to amply support the spindle 30 upon downward movement of the knife blade |06 to cut the coil formed by the machine, a support |20 is provided which has a V-shaped notch |22 in its upper end adapted to receive the spindle 30 and support it, the lower end of this support |20 being connected to the front wall 6 of the machine in any desired manner.
As before stated, solenoids 56, 86 and ||2 are disposed in a control circuit, this control circuit being diagrammatically shown in Figure 6 of the drawings. Operation of the solenoids effects certain operations in the coil forming machine. As pointed out, solenoid 56, when energized, causes gripping action between the cooperating feed rolls for the wire whereby the wire is fed to the spindle 36. Solenoid ||2, when energized, moves the lever |02 whereby the knife blade |06 is moved down into engagement with the coll to sever the same from the remaining portions of the wire. Furthermore, upon upward movement of lever |02, lug 4 operates switch ||8 to energize solenoid 86 whereby member 66 is moved to discharge the cut length of coil from the receiving means therefor. 'Ihis cycle of operation is continuous so that the machine is entirely automatic, requiring no manual manipulation after the switch is thrown to energize the control circuit.
The control circuit comprises a switch |26 for including the same in circuit with the power lines |28 and |30. When the switch is thrown, a circuit is established through the lead |32 to contact |34, contact |36, through leads 38 and |40, through a relay |42, and then through the lead |44, contacts |46 and |48 ofthe control relay |50, then through contact |52 of this control relay and through the lead |54. The completion of this circuit closes the time delay relay |42 and establishes another circuit through lead |32, contacts |34 and |36, lead |38 and lead |56 to the solenoid 56, and then through lead |58 through the contacts |60 and |62 of the relay |42, and
thence through lead |64 and lead |66 through contact |52 andV lead |54, thereby energizing the solenoid 56 which immediately effects downward movement of the lever 50 about pivot point 52 toV apply pressure moving rolls I4 and I8 into wire gripping engagement to feed wire to the coil forming means.
At this point it should be noted that a transformer |68 is energized at all times when the switch |26 is thrown in, inasmuch as the high side |10 thereof is connected to contacts |34 and |52 on the 220V Volt lines |32 and |54, the low side |12 thereof being connected through lead |16 and through lead |14 which includes switch 90 to coil |5| of the control relay |50.
After the solenoid 56 has been energized to cause feeding of the Wire, the coil continues to be formed by the coil forming means until the end of the coil engages contact 98 of switch 90 which moves this contact into engagement with contact 96. 'I'his completes a circuit from the low side of the transformer through the lead |14, the switch 90, through the main control relay coil |5| and through the lead |16. This energizing of the coil 5| causes the main control relay to close, thus opening contacts |46 and |48, and to close contacts |52 and |53 thereof. This movement of the main control relay causes the relay |42 to open, which in turn breaks the circuit in which vsolenoid 56 is placed, as 4above described, to relieve pressure on the rolls |4 'and |8 so that the Wire feeding means is inoperative.
The closing of contacts |52 and |53 of the control relay, upon energization of coil |'5|, completes a circuit from lead |32 through contacts |34 and |36, through lead |18, through the solenoid l2 and to lead |88, to contact l|53 through the control relay to contact |52 and thence through lead |55. Energization of the solenoid 2 moves the lever |02 about pivot point v|04 to bring the knife blade |06 into cutting relat-ion with the wire and to sever a portion of the coil at that point. Upward movement of lever |82 through the lug 4 causes a closing of switch |8 which completes a circuit from lead |32, contact |34, lead |82, throughswitch 1| I8, solenoid 86, leads |84 and |65, contact |52, through lead |54. Energization of solenoid "B6 causes a movement of link 82 to rotate lever 48|), thus moving rod 'I4 and member 66 to discharge the coilfrom the coil receiving means.
After the coil has fallen through the opening between members 64 and 86, pressure is relieved from contact 98 of switch 98 which opens, thus breaking the circuit including the coil |5| of the main control relay |58, thus breaking the circuit through contacts |52 and |53 whereby the lever |82 is returned toits initial position and the circuit of the relay |42 is completed through contacts |48 and |48. Movement of lever |82 to its initial position opens switch |8 to deenergize the circuit including solenoid 86 whereby the member 88 is returned to its initial position 4forming the V-shaped trough with member 64. The closing of the circuit of the relay |42 through contacts 45 and |43 energizes the relay |42 so as to complete a circuit through the contacts |60 and |52 thereof, which causes ldeenergizing of solenoid 56, thus placing the control circuit in condition for another complete cycle of operations.
The main control relay may be wound with wire of large diameter, as is well understood, so that there is a time delay lbetween the opening of contacts |46 and |48 and the closing of contacts |52 and |53. This assures a complete deenergization of the wire feeding circuit vbefore energization of the wire cutting circuit so that the coil of wire is stationary at the time -the cutter blade contacts the same. Any suitable means may be used in association with the main control relay to effect this time delay of any desired amount.
It is also to be noted that the length of coil being formed by the machine may be varied as desired by adjusting switch 98 lthrough the means 84.
While I have herein described Yand upon the drawings shown an illustrative embodiment of the invention, it is to be understood that the invention is not limited thereto but may comprehend other constructions, arrangements of parts', details and features without departing from the spirit of the invention.
