means for reversible gearing to more accurately 7 control the length of the strokes of the carriage; improved means for varying the length of the strokes of the carriage in coil-winding machines to wind cores of different lengths, which includes a visual and manually-adjustable indicator for expediting the setting of the machine for carriage strokes of different lengths; and other features which will more fully appear from the detailed description.
The invention consists in the. several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof. i
In the drawings: Fig. 1 is a plan, parts being shown in section, of the mechanism for reciprocating the carriage and the controlling mechanism therefor, the carriage being illustrated adjacent its out-stroke. Fig. 2 is a horizontal section illustrating the carriage at the end of its in-stroke. Fig. 3 is a vertical section on line 3-3 of Fig. 1. Fig. 4 is a vertical section on line 4-4 of Fig. Fig. 5 is a section on line 5-5 of Fig. 30 1. Fig. 6 is a vertical section on line 6-6 of Fig. 5. Fig. 7 is a front elevation of the dial and the arms for indicating the position of the carriage and varying its stroke.
The invention is exemplified in a winding machine which comprises a driven arbor 24 which is adapted to receive a core a on which coils of wire are to be wound and a reciprocable carriage b which carries guide-arms b which carry grooved rollers b for guiding the wires to the arbor. The machine may be equipped with wire guides for simultaneously winding any desired number of coils on any suitable core or cores on the arbor 25. The machine comprisesa supporting base 2| and a housing 22 rigidly secured on by variable speed gearing such as is exemplified in my patent application filed December 9, 1935, Serial No. 53,4 6, to vary the speed of travel of the carriage 2) according to the gauge of wire to be wound on the core. A bevel gear H4 is fixed to shaft III and provided with a clutch-member I I5 provided with radial teeth on its outer face. A bevel gear H8 is journaled on a fixed stud H9 and meshes with bevelled gear H4. A shaft I05 is journaled in a stationary bracket I06 in the housing 22 and a combined radial and thrust bearing I08 in the clutch-member H5. A bevelled gear I I6 is loosely mounted on shaft I05, has affixed thereto a toothed clutch-member I I1, meshes with bevel-gear I I8 and faces the gear II4. A clutch-sleeve I20 is splined to and slidable on shaft I05 and is provided with clutchteeth at its opposite ends to mesh with the clutch-members H5 and H1, respectively. When the clutch-sleeve I20 is coupled to bevel-gear H4, shaft I05 will be driven in one direction directly from gear II 4. When sleeve I20 is disengaged from gear H4 and engaged with clutchmember II'I, shaft I05 will be driven in the opposite direction from gear H4 through intermediat-e idler gear H8 and gear H6. Sleeve I20 is 2 automatically shifted and controlled by mechanism hereinafter described to reciprocate the carriage b for the wire-guides. Shaft I05 is secured to a screw I01 which is threaded to a nut I09 which is fixedly held on the cross-head b and against rotation by a boxing H0 which is secured to said head. The outer end of screw H1 is journaled in a'bearing I0'I in a wall of the housing 22. Rotation of the shaft I05 in one direction will cause the screw 01 to rotate in the non-rotatable nut I09 and move the nut I09 and the carriage b in one direction and reverse rotation of shaft I05 will rotate screw I01 to move the nut I09 and the carriage b longitudinally in the reverse direction.
The machine includes mechanism for automatically shifting the clutch-sleeve I20 to impart strokes of different lengths to the carriage b for winding coils of different lengths. This mechanism comprises a transverse shaft I15 which is journaled in a bracket I'I5 fixed on the base 2|, and gearing for driving said shaft in opposite directions and in accordance with the shaft I05 which operates the screw I0'I. Said gearing-comprises a worm III fixed to shaft I05; a worm gear I'I2 engaged by said Worm and fixed to a shaft IIil which is journaled in upstanding lugs on bracket I06, a pinion I13 fixed to shaft I12; a gear II'4 fixed to shaft I15 and meshing with pinion I13.
A shifter collar I83 is adapted to slide clutchsleeve I20 into engagement with either of the gears H4, H6 to drive shaft I05 and screw I01 in opposite directions. A lever I84 for shifting collar I83 is fulcrumed at I85 to swing horizontally and is provided at its outer end with an abutment plate I88. An abutment-arm 205, controlled by a rotatable cam I82 on shaft I15 and an abutment arm 204 controlled by a cam I8I also rotatable with said shaft, control the movements of lever 34 and clutch-sleeve I28 at the ends of the in and out-strokes of the carriage b to lock the clutch-sleeve in its engaged positions during the strokes of the carriage. These abutment arms alternately lock and release said lever under control of said cams. Adjustable stops 20I are provided to limit the travel of lever I84.
Cam I82 is fixed on a hub which is fixed to shaft I15. Cam I82 is adapted toengage an arm 206 on a rocker 202 'to-which abutment arm 205 is fixed. Cam -I8I" is fixed on a clutch-member I11-and is adapted to engage an arm 208 on rocker 202 which is loose on a shaft 202 This shaftextendsthrough rocker 202 and abutment arm 204* is fixed to said shaft. An arm adapted to be'struck by cam I8I' is fixed to shaft 202.
A spring 2I0 is applied to an extension on arm 205. to pressarm' 208 towards the face of cam I82 and arm 205against the outer faceof the abutment-plate I86 when the arm 205 is held by the outer edge of said plate. A spring 2H is applied to an extension on arm 204 to rock arm 208 toward cam I8I and to hold arm 204 againstthe outer edge of, abutment-plate I88 when the latter arm is arrested by said outer edge. Shaft 202 isjournaled in brackets 283.
Theinvention provides for readily varying the 22. This index arm follows the movement of the cam I82-and indicates its position; A nut 2I3 holds the indexarm 2I2 on the front end of shaft I15. An index arm I is fixed-to rotate with a sleeve I18 which extends around shaft I15 and is journaled in head I19. Sleeve I18 is pinned to clutch-member I11. =A spring 2I5 is adapted to pressclutch-members I16, I11 apart when the-nut 2 I3 is loosened or removed from the front end of shaft I15 to permit indexarm I80 to rotatively adjustclutch-member-I11 with its cam I8'I to varythe arc of travel between cam I8I. and arm 208 The spacing between'index arms I80 and 2I2 and corresponding spacing-between cams I82 and I83 will control the lengths of the strokesof carriage b. Whenachange in the'length of the stroke is desired; the-operator will loosen'nut 2I3 so that index-arm I80 whichis fixedly connected to clutch-member I11 which car-ries cam 'I8I can be rotatedrelatively to its coasting clutch-memberHB to effect a diiferent setting between the index arms and a corresponding variation in theperio'ds'between the movements of the clutch-sleeve I20 of the reverse gearing for reciprocating the carriage. The rot'a tive adjustment of cam ISI relatively to the arm 208 engagedthereby varies thelength of the strokes of the carriage to adapt the machine for winding coils of different lengths. During the" operation of the machine, index arms ifiii, 2I2 rotate together and the graduations between said arms indicate the length of the carriage stroke for which the machine is set. This exemplifies means which is easily, quicklyand acurately adjustable to vary the length of the carriage strokes for winding coils of diiferent lengths.
A pair of rods I81 are adjustably secured to projecting lugs on shifter collar i533; are slidable in and through bracket E05 and are cross-connected by a bar I88. Springs E88 are applied between bracket E08 and collars 589 which are shouldered against and slidable on rods 581 and in the cross-bar I88 to exert pressure to the rod on cross-bar I88 to engage and shift, through rods E81, the collar E88 so that sleeve 528 will engage bevel-gear H8 when the controlling lever I04 is released by arm 28 3, as the result of the cam lSI- shifting arm. 288, shaft 202 and arm 2%. This occurs at the end of each out-stroke of the carriage b and the points at which the out-stroke terminates and the Lin-stroke begins are variable by the rotative adjustment of cam IBI and clutchmember I11, as before described. This constitutes index-controlled mechanism for varying the lengths of the strokes of the reciprocating carriage;
Collar I83 is reversely shifted for engaging sleeve i20 and bevel-gear H 5 at the end of each iii-stroke of the carriage by a pair of abutmentcollars 208 which are fixed on rods 288. The outer ends or rods 280 are fixedly secured in cross-head b so they will reciprocate with the carriage and. their inner portions are slidable through collars I88 in cross-bar I88. The inner ends of rods 208 are slidable in bracket I88. Washers i90 are slidable on rods 208 and are pressed against collars 288 by springs I98 which are interposed between said washers and the cross-head b During the in-strokeof cross-head b collars 200 engage the collars I89 and relieve the cross-bar I88 from the pressure of springs I89. Thereafter the spring-pressed washers I88 engage the cross-bar 588 to apply the pressure of springs I88 to said cross-bar to cause the collar 83 to be shifted to the left as soon as lever E84 is released by arm 285 under control of the cam I82 and arm- 205. This spring-pressed means for shifting the clutch-sleeve of the reversible gearingat the end of the in-stroke of the carriage exemplifies a construction by which spring-pressure will be applied-to the sleeve before the controlling mechanism releases the lever i84 for its respective movements for a quick and accurate timing of clutch-sleeve I28 in the reciprocations of carriage b.
The operation of the-machine will be as follows: the operator will place a core of any suitable type on the arbor 20. The ends of the wires from the supply reels will then be directed around the guide-sheaves b andsecured on the core. The operator will set the indicator arms I80 on the dial 2I4 and relatively to the index 2I2 to correspond to the length of the coils desired. In this setting, cam I 8I will be rotatably adjusted to its arm 208 to vary the timing or periods between the shifting movements of clutch-sleeve I20 of the reverse gearing for reciprocating the guide-carriage. After the setting has been made, nut 2I3' will be-tightened to fix clutch-members I 18, I11 together-to fix the relative rotative spacing between cams I8! and I82. This will result in'varying' the length of the carriage strokes. Assuming the carriage b' to be approaching the end of its out-stroke, as illustrated in Fig. 1, cam I8I will engage arm 208 at the desired point. The cam will rock arm 208, shaft 202 and arm 284 against the force of spring 2. Arm 264 will be moved outwardly to release abutment I36 on lever I84, whereupon the force of springs I89 will be applied through cross-bar I88 and rods I81 to collar I83 to instantaneously shift sleeve I26 into engagement with gear II6 to start the in-stroke of the carriage. As soon as the lever I84 is shifted, spring 2 I I] will rock arm 265, rockor 202 and arm 266 to cause arm 285 to move toward the fulcrum of lever I84 and into position to lock abutment plate I86 on said lever in position to keepsleeve I20 coupled to gear I I6 during the in-stroke of the carriage caused by the reversal of shaft H25 and screw I81. When the carriage b approaches the end of its in-stroke, the mechanism for shifting the collar I83 will be in position illustrated in Fig. 2. At such time collars 29?) will have engaged spring-pressed sleeves I39 to disengage the collars from crossbar I88 and washers I96 will be pressed against cross-bar I28 by springs I96 to force the crossbar'and rods I81 inwardly to shift clutch-collar I83 and sleeve I28 into engagement with gear II4 as soon as lever I84 is released by arm 265. This release of arm 265 occurs when cam I82 strikes arm 206 and thereby rocks arm 265 into position shown in Fig. 1. When arm 265 is thus rocked, lever I84 will be shifted by the force of springs I89 to couple sleeve I28 with gear H4 and arm 205 will then rest against the outer edge of abutment-plate Hi6 and be held against retraction by said plate during the out-stroke of the carriage. At the end of the in-stroke of the carriage, arm 2% will be held by abutment-plate I86 while the latter is locked against pivotal movement by arm 265 until the end of the outstroke of the carriage.
