Abstract
A wire coil production system for winding, tieing and distributing coils fabricated from pre-cut wire segments. Four controllably driven mandrels or reels (7) are mounted in relative quadrature on a rotatable turret (6) which cycles each mandrel through stations (A to D) for (1) receiving the wire (16) and initiating the winding operation, (2) completing the winding operation, (3) tieing the formed coil and (4) discharging the coil to a conveyor/distributor system. Each mandrel includes a wire sensor (26, 27) and automatic wire clamping and coil load/unload mechanisms. A control system (93, 95) coordinates all operations so they are synchronized with the wire feed system and with each other.
Description
- The present invention relates to equipment and processes for automatical fabrication of coils of wires from wire segments received from for example, a wire processing system, and sorting and delivering the finished coils.
- There are a wide variety of wire coiling systems directed at automating one or more phases of the coiling process to increase throughput. One common approach is to use multiple spool or multiple mandrel heads often mounted on a rotatable turret and indexed through various stations for loading, winding, and discharging the coils.
- Generally speaking these systems coordinate the various station functions so that loading of one mandrel is completed at the winding station before winding of the next coil in the sequence begins. Often the system is fed from one continuous supply of wire and the severing of the feed from the fully loaded mandrel also plays a role in engaging the severed feed end to the next mandrel or spool to be loaded.
- While a fair degree of automation is achieved with the foregoing arrangements, their construction and modes of operation do not lend themselves to the continuous winding and tieing of pre-cut wires, which may'be of varying lengths, at throughputs which`mateh the primary wire segment forming process.
- It is accordingly an object of an embodiment of the invention to fabricate wound and tied wire coils of varying lengths at high production rates. Another object of an embodiment is to implement this production for smooth coordination with wire processing, and coil sorting and transporting mechanisms. Still another object of an embodiment is to reduce the interdependence between system modes of operation which has heretofore characterized many approaches, thereby reducing constraints on optimizing system operation. Other objects of embodiments of the present invention include improving the engaging winding, tieing and discharge functions and improving the control system for these and other proc- cess parameters.
- According to the present invention there is provided a coil production system which includes a set of rotatable mandrels, each having wire sensing means, means for engaging a pre-cut feed wire, means for constraining the wire in a coiled configuration as it is wound and means for discharing the wire after the winding operation is completed; controllable mandrel drive means for rotating each mandreL during certain phases of the coil forming operation; feeding, coiling and discharge stations; indexing means for moving each mandrel successively past the feeding, coiling and discharge stations and a control system for controlling the mandrel drive control, the indexing mechanism and the feeding, coiling and discharge stations such that engaging, coiling and discharging operations are carried out concurrently to provide continuous production of coils.
- According to a further aspect of the present invention there is provided a coil forming process comprising the steps of:
- (1) engaging a first wire segment at a first station and initiating the coiling thereof;
- (2) spacially displacing said partially coiled first segment to a second station for the further winding thereof;
- (3) engaging a second wire segment at said first station and commencing the coiling thereof;
- (4) engaging a third wire segment at said first station;
- (5) spacially transporting said coiled first segment to a third station and said second wire to said second station where coiling is completed;
- (6) cyclically repeating the above steps with succeeding wire segments to provide a continuous supply of coils.
- Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
- Figure 1 is a perspective and partially schematic view of a coil production system according to an embodiment of the present invention,
- Figures 2, 3 and 4 are perspective views,on an enlarged scale, of the turret and mandrel assemblies of the system illustrating various phases of system operation;
- Figure 5 is an elevational and cross-sectional view taken along the lines of 5-5 Figure 1;
- Figure 6 is an elevational and cross-sectional view taken along the lines of 6-6 Figure 5;
- Figure 7 is an elevational view of the turret and mandrel assemblies viewed from the indexing side;
- Figure 8 is an elevational and partially fragmentary view of the mandrel located at the tieing station;
- Figures 9 and 10 are fragmentary elevation and plan views, respectively, of one mandrel and with its wire clamping and reset mechanism;
- Figure 11 is a schematic diagram of.the control systen.
- The embodiment illustrated in Figure 1 employs four
identical mandrel assemblies 7, each rotatably mounted on aturret 6.Shaft extensions 5 and 9 of the turret facilitate its rotation relative to the machine frame 2 as will be described subsequently. The entire system including frame, turret and motor drives is mounted in a movable assembly which can be positioned relative to wire processing and coil distribution sites. - The
mandrels 7 are rotatably driven for coil winding operations by a servo-controlled motor Ml which through ashaft 17 coaxial withaxle 5, and a transmission system withinturret 6, drives the mandrels during certain phases of operation. - A
pre-cut wire segment 16 to be coiled is ejected from a wire processing unit, not shown, which may be, for example, a wire marker machine, a stripper etc., and is fed to eachmandrel 7 in turn via a guide system which includes a threading die 36 andwire sensing unit mandrel housing 34 and engages a wire clamp 15 on aplate 10 of the mandrel. - When the presence of a wire is detected by the
sensor drive shaft 17 causing it to rotate. This rotation causes clamp 15 on each reel to clamp the leading end of the respective feed wire. Coiling then commences. - As the coiling operation commences an indexing function occurs with each mandrel being displaced to the adjacent quadrant. The mandrel at position A for example is rotated to a position "B" (Figure 1) simultaneously carrying its feed wire with it and continuing its winding operation. The mandrel and its coil at position "B" moves to "C" in preparation for discharge. The now-empty reel asembly at position "D" moves into the "A" position in readiness to receive the next feed wire. This is accomplished with an
indexing mechanism turret 6. - When the trailing end of the wire being coiled at the mandrel (which is now at position B) passes through the
respective sensor drive shaft 17 and winding stops. - During the following indexing operation, the reel is rotated to positionCwhere the wire coil is tied. It is then indexed to position D where the coiled and tied
wire 55 is discharged to a conveyor 47 which delivers it to one of thedischarge bins 56, via arespective deflector gate 57. - These operations are carried out continuously and automatically as pre-cut wire segments are fed to the machine; they are engaged, wound, tied, and delivered by the system to the conveyor.
- As shown in detail in Figure 2, a length of
wire 16 is guided to themandrel 7 at the wire feed station with the aid of a pair ofrollers 20A, 20B and thethreading die 36 which directs the wire throughsensor reel casing 34 to the rotor assembly of the mandrel. To this end, eachdie 36 is pivotally mounted on the turret between a pair of flanges 36B and has awire guide tube 36A at its opposite end. A cam 90 at the feed station rocks the die arriving at thatstation causing tube 36A to pass through thesensor mandrel housing 34 to provide a conduit for guiding the wire into the mandrel rotor assembly. - Each of these assemblies includes a
circular plate 10 mounted on aspindle 32 having acap nut 80. Each plate has a serrated periphery, in the notches of which V-shaped rim segments 11 are pivotally mounted. The latter are distributed around the periphery ofplate 10 to define a concave wire engaging surface. 1 - This surface is located within the associated
mandrel housing 34 with the inwardly located leg of each rim bearing against aflange 34B (Figure 5) fixed to the housing. Each housing is secured to turret 6 withbrackets 34C. - The peripheral rim segments 11 are each secured to a fitting 12 (Figures 2 and 5) pivotally mounted on a
respective pin 12A which bridges each notch inplate 10. - In the winding and tieing modes each
fitting assembly 11, 12 is positioned as shown in Figure 2 and in the upper mandrel of Figure 5. This positioning is controlled by acam follower 41 onspindle 32 each mandrel and arespective spring 44 which urges the cam in a radially inward direction.Links 43 interconnect the follower and eachrim assembly 11, 12 thereby maintaining the latter with theirstops 12B againstplate 10. - This coil engaging position is changed when the mandrel arrives at the discharge station shown at the bottom of Figure 5. For this purpose a
cam 46 is provided on the machine frame 2 to displace the arrivingfollower 41 outwardly against its associatedsprinq 44. - As this occurs, the actuator links 43 eccentrically rotate their
respective rim assemblies 11, 12 to the position shown in Figure 5 (bottom mandrel) and in Figure 6, releasing the wire clamp as described in the next section and permitting the wound and tied coil to slide off the mandrel and on to the conveyor 47. When the mandrel is thereafter indexed to the feed station "A",spring 44 causesfollower 41 to retract and the rim assemblies 11, 12 to return to the wire engaging position. - A wire clamp lever 83 (Figures 9 and 10) is pivotally mounted on each
mandrel plate 10 withpivot assembly 83A. The outer end oflevel clamp 83 includes aclamping surface 83B which is in facing relationship to a stop 84 (Figure 10) fixed to plate 10. - In the position shown the facing surfaces of stop 84 and
lever clamp 83 are separated to receive awire end 16 fed to the mandrel. When rotation of the mandrel commenceslever 83 is tripped and itsclamping end 83B moves towards stop 84 thereby to clamp the wire end. - This tripping is accomplished with a cam and follower arrangement which includes a cam 80 (Figure 9) mounted on the associated
housing 34 below therespective plate 10. The cam is engaged by the cam follower leg 81A of alatch 81. The latch is pivotally mounted to plate 10 with aclevis 82 having apivot pin 82A. Asection 81B oflatch 81 extends through an aperture 10B inplate 10 and engages thewire clamp lever 83.- A spring 81C urges the latch towards contact with thecam surface 80. - When rotation of the mandrel from its reset position begins, follower 81A rides up on
cam 80; itsend 81B moves downward (Figure 9) and out of the engagement withclamp lever 83. At this point a spring 85 (Figure 10) connected betweenplate 10 and a tab 83D onlever 83, pulls the clamp lever into the wire engaging position. - For resetting the clamp, a clevis 88 is pivotally mounted on a
tab 89 integral with one of therim assemblies 12 and includes ashank 88A which passes through a hole in a tab 83C onlever clamp 83. A spring 88B onshank 88A resiliently separates the lever clamp and rim assembly. - When the illustrated mandrel arrives at the discharge station, the
rim assemblies 11, 12 are pivoted as previously explained. This action causes clevis 88 and its shank 88B to rocklever clamp 83 into its release position, thereby releasing the wire end. When this occurs,latch section 81B, previously blocked bylever 83, moves upward through hole 10B to assume its reset position and to holdclamp 83 in its cocked position in preparation for the next clamping action. - The motor Ml (Figure 1) supplies drive for the mandrels via a pulley and belt system, the driven
pulley 35 of which is fixed to main drive shaft 17 (Figure 2). As described in a following section, motor Ml is controlled by the tachometer-generator 19. - As shown in Figure 5,
shaft 17 is journaled inaxle 5 and drives amaster bevel gear 21. The latter drives a set of four planetary bevel gears 22, one for each mandrel. - Each gear 22 is connected to a
clutch assembly 23, 24, the output of which is connected to therespective spindle 32. Each clutch is controlled in turn by a switchingunit 31, which is responsive to the associatedwire sensors switch unit 31 causes the clutching system toclutch shaft 32 to driven gear 22 thereby causing rotation of the mandrel to commence. - As each mandrel with its coil of wire moves from position B (Figure 1) to position C, the coil tieing operation is initiated. For this purpose, the tieing section at location C includes a pair of diametrically ; opposed tieing mechanisms embodied as hydraulic actuators 50 (Figure 4 and Figure 8). Each includes an hydraulic cylinder 53 mounted on a bracket 53A secured to the machine frame 2. Each cylinder actuates a
piston rod 52, the distal end of which is connected an ;applicator 54. Under the control of a valve system, not shown, eachpiston rod 52 moves inwardly toward the coil of wire with itsapplicator 54 passing through cut-outs 34A inhousing 34 to loop a tie or tag around the wire coil. To provide clearance for this action, therim assemblies 11, 12, which are otherwise equally spaced, include two pairs with greater spacing to accommodate cut-outs 14 inplate 10. Therods 52 then retract, pulling theapplicators 54 outside and clear of themandrel housing 34. ' - When the tieing or tagging operation is completed, an indexing step occurs which moves the tied coil to the discharge station D and brings a new coil to station C for the tieing operation.
- Each time a mandrel engages a wire segment and begins its coiling operation, the
turret 6 is indexed 90°. This operation is initiated by each wire sensing unit when it senses the presence of a new wire segment. A motor M2 responds to this signal via amotor control unit 95, (Figure 11) driving through a belt andpulley system rotor 28 fixed to shaft99A carrying pulley 99. The rotor includes aneccentric pin 29 which is positioned to engage slots 30 ingeneva wheel 25. The latter is fixed to axle 9 of theturret 6. - Each time motor M2 is energized,
rotor 28 rotates thegeneva wheel 25 through 90° to provide the indexing action . Amicroswitch 97 is tripped after each 90° displacement to provide an appropriate control signal to motor M2. - Control over the operation of the system is ! schematically indicated in Figure 11. Motor Ml provides drive.to each of the
mandrels 7 via respectiveclutch units 23, 24 and their associatedswitching units 31. Each time a wire traverses awire sensor 26, the associated clutch is energized causing motor Ml to drive the mandrel to which it is connected. Control over the speed of motor Ml is provided byfeedback tachometer 19, also shown in Figure 2, whose signal is compared with a reference speed signal supplied tomotor 93. - During the wire engaging interval, a wire sensing signal is coupled from the involved wire sensor to
motor control 95 which responds by actuating M2 to initiate an indexing operation. Completion of the resultant quadrature displacement momentarily actuates theswitch 97.Motor control 95 responds by deenergizing motor M2. - In a preferred embodiment, the motor control system is embodied as a microprocessor based programmable controller, which in addition to receiving the inputs shown in Figure 11 also receives inputs from sensors which detect whether the mandrels in position B have stopped rotating and whether the
coil tieing actuators 50 are retracted. These additional inputs insure that indexing occurs after a wire has been seized for coiling but only provided that the mandrel at station B is stationary and the coil tieing actuators are engaged and clear of the mandrel at station C.
