This invention relates to winding machines of the type having a bobbin holder for receiving and driving the bobbin to be wound, and having a guide movable alongside the bobbin for feeding the wire, thread or other elongated material to the bobbin and laying it as the bobbin rotates.
It is desirable in machines of this type to be able to vary the total traverse of the guide, for example to suit bobbins of difierent length, and
also to be able to vary the pitch of traverse, that 2 is to say the number of turns per inch in the length of the bobbin. It is also desirable to be able to make adjustments for these purposes without interfering with the continuous operation of the machine.
This invention has for its object, therefore, to provide a mechanism which gives an infinitelyvariable adjustment both of the length of traverse and the pitch of traverse, and which also can give a variable period of dwell at each end of the traverse movement.
The invention comprises pivotal means for moving the guide, and means for varying the position of the pivot so as to shorten or lengthen the guides total movement. The invention also comprises pivotal means for imparting a step-by-step motion to the guide-moving means, and means for varying the position of the pivot so as to shorten or lengthen the individual increments of the guides movement.
Considered from another standpoint, the improved machine comprises a continuously-operable uni-directional driving member, means for converting the continuous uni-directional motion into a step-by-step uni-directional movement, and further means for converting the step-by-step uni-directional movement into a step-by-step to-and-fro movement; with means for varying the size of step in the step-by-step motion and means for varying the extent of the to-and-fro motion.
The invention is illustrated in the accompanying drawings, wherein- Fig. 1 is a side view of the mechanism, bobbin holder being viewed endwise;
Fig. 2 is a plan of the same;
Fig. 3 is a front view;
Fig. 4 is an enlarged sectional view of means for holding and driving the bobbin;
Fig. 5 is a fragmentary view, partially in section, of an alternate cam arrangement for the main cam drive;
Fig. 6 is a view of the same mechanism taken at right angles to the view shown in Fig. 5;
Fig. 7 is a fragmentary top plan view of the same mechanism; and
Fig. 8 is a plan view of the lever bar, cam frame, and associated mechanism.
Referring to Figs. 1, 2 and 3, the machine comprises a frame indicated generally by I, a driving the the
Slidable in guides M across the front end of the machine, such guides extending from the end of the top plate la, is a traverse bar 5, to which is rigidly secured the guide 16, this guide embodying spaced plates H which slightly separate the multiple wires being wound, -a steady roller !3, and a final guide roller 19. A clamp (not shown) may be incorporated between the rollers I 8 and IQ for holding the ends of the severed wire when the bobbin is being changed. As thetraverse bar 15 moves to-and-fro in its mountings, the guide 16 moves to-and-fro over the length of the bobbin in the bobbin holder.
The bobbin holder (see Fig. 4) comprises a headstock 20, with spindle 2| carrying the pulley 9, and a tailstock 22 with retractable spindle 23,
the tailstock being of clamp form; with tightening lever 24 for gripping the spindle 23 in its advanced position. The forward end of headstock spindle 2! has a centre plug Zia to enter the bore of the bobbin shown in broken lines at 60, this being on an interchangeable plate 2Ib, held in position by the threaded inner terminal 26a of spindle 2! which passes through the headstock and has a knurled knob 6| at its outer end. A pin 2k: carried by such plate enters a hole in the bobbin flange to form the driving connection. The tailstock spindle carries a rotatable centre 23a mounted on an anti-friction bearing 62, and has a rubber or like pad 231) to absorb the shock and reduce the noise of contact with the tailstock.
The traverse bar I5 is pivotally connected at 541. to one end of alever or rocker arm 25 which is mounted on a pivot 26a extending downwardly from a nut 21 on a lead screw 28 mounted in the fixed bearings 29, and the other end of such arm 25 is connected to a cam frame.30 hereinafter referred to. Such lead screw 28 is manually rotatable by means of a hand-wheel El and bevel wheels 32, to vary the position of the nut 21 and thereby varythepivotal relationship of thenut 21 and lever arm 25, the arm bein slotted, as 'shown at 64 (see Figsszdand 8), to receive thejpivot 26a, and the pivot haying clamping means such as nut 26 to lockit in the adjusted position on the arm 25: 1"Although the manual adjustment means is showri'towards the rear of lead screw 28, it could be at or near the forward end, and inv such case the bevel wheels could be dispensed with, the hand-wheel 3| being mounted on the end of lead screw 28.
Below the said other end of such lever arm is a vertical shaft 33 carrying the main cam. 35 near its top end, the cam being keyed to the shaft as shown at 34c, which cam is heart-shaped and operates the said cam frame to-and-fro to oscillate the lever arm 25 about its pivot 26a. The said shaft 33 is not power driven, but it carries three one-way roller and wedge. clutches 35, each of which is operated by a rack 36 mounted to reciprocate in suitable guides 31. Each rack engages an exteriorly-toothed outer part 35a of the clutch so as to oscillate that part to-and-fro. These racks 36 are connected, respectively, to three pivotally-mounted rods 38, whose other ends are operated, respectively, by the said identical, oppositely-disposed cams. I3 on shaft l2.
Actually, the cams. I3 engage rollers Ilia on lateral extensions. 38a of rods 38, whilst compression springs 35a cooperate with the racks 35 to keep the rollers I3a in, contact with the cams I3. The arrangement is such that as the cams I3v rotate, the said rods 38 are oscillated, and first one and then another gives an increment of movement (in the same direction) to the main cam shaft 33. Such rods 38 are each pivoted in a bar 39 which incorporates a pair of nuts 40 on two additional lead screws 4! so that, by rotation of these lead screws M, the position of the pivots may be varied and the effective stroke of the cams thereby adjusted. The nuts secured to the bar 39 are transversely movable by means of the lead screws 4 I, i. e.: rotation of the threaded lead screws 4| imparts lateral movement to the congruently threaded nuts 4! which are secured against rotation. Thus the bar 39 may be made to selectively traverse the lead screws 4|. It is evident that with the changing of the fulcrum or pivot point, the stroke of the racks 36- are likewise effected. For example, if moved leftwardly, Figs. land 8, the bar 39 alters the pivot point of the rods 38. With the stroke of the extensions 38a remaining constant, the stroke of racks 36 will therefore increase. Analogously, rightwardly positioning of bar 39 results in a reduction of the stroke of the racks 36.
The controlled variance in the racks 36 produces a similar variance in the increments of rotation of the main cam shaft 33. As, shown, the rods 38 have a universal mounting in the said bar 39, being retained in position by the attached bosses 39a. Each lead screw 4| carries at its forward end a toothed wheel 2-2, both of which mesh with a wheel 43 operable by means of. a hand-wheel or finger knob 54.. Rotation of member 44 rotates lead screws H to traverse pivot bar 39.
The cam frame 30 has supporting guides 45 carried by brackets, 58, and has upstanding rollers 41 to engage the cam at opposite sides. A slotted lug 48. at the rear end of the lever arm 25 receives a pin 45a carried by the cam frame as.
In use, the motor 2 drives the bobbin holder, and also the three identical cams I3. These cams I3 impart step-by-step. rotation to the main cam 34, the size of step depending on the position of the pivot bar 39, for the rack-operating rods 33, andthe main cam Z lbscillates the slotted. lever arm 25 to reciprocate the traverse bar I5 and guide I6. The total length of traverse depends 'pon the position, of the pivot 26 for the slotted lev r 12 5 In order to obtain a dwell (if required) at the and of the traverse of bar I5, the pivot I5a, which depends from a block I5b carried on the upper surface of said bar 55, engages the bar I5 indirectly by means of the opposed screws I5c. The traverse bar is provided with an elongated slot 63 through which a pin 66 connecting block I52) and pivot !5a passes. In Fig. 2 screws I5c are shown in contact with block I5b so that no dwell would result. By retracting one or both screws a lost motion is introduced between lever 25 and bar I5 at eachv end of the traverse.
The spaced plates IT on the guide IE are secured by a wing nut Ila on its supporting stud, and such stud is movable in a slot I'ib to vary the position of the plates IT on the guide. The steady roller is and guide roller I9 may be similarly adjustable.
It is believed that the operation of the machine will be largely clear from the foregoing description. Motor 2 drives main drive. shaft 3, which, in turn, drives the. rotatable bobbin holder. Drive shaft 3 further impartsv rotation to cam shaft I2 through the worm gear con.- nection. Cams I3 arev keyed to cam shaft I2, and accordingly rotate therewith. This rotation imparts a rocking movement. to rods 38 which are fulcrumed at 35. This imparts a rocking movement to the opposite ends of rods 38,. which opposite ends are connected with racks 36. These racks engage pinions 35a which operate one-way roller and wedge clutches 35. Thus, there is imparted to cam shaft 33 alternating rotary movement. Speed of rotation of this shaft is varied, by varying the position of fulcrum 39 providing the intermediate supports for rods 38. There is thus provided a simple and inexpensive variable speed mechanism for driving cam shaft 33.
34 is, of course, keyed to shaft 33,, and as cam 34 rotates it imparts reciprocating move.- ment to cam frame 30. This, in turn, imparts rocking movement to main lever arm 25, the opposite end of which is operatively connected to the traverse bar I5 which supports the. guide rollers for the wire being wound upon the bobbin. Variation in traverse. of this bar is effected by adjusting the position of the pivot 26a intermediate the ends of lever arm 25. Such adjustment is eifected by loosening nut 26, and then rotating hand-wheel 3| which rotates lead screw 28.
In the event that no dwell is desired at the end of each traverse of the traverse bar, screws i5c are tightened so that there. is no relative movement between such screws and block I5b.. In the event, however, that some dwell or lost motion is desired at the end of each traverse, screws 50 are appropriately moved. outwardly from tight engagement with block I51), and accordingly, at the end of each traverse, return movem nt of lever arm 25 imparts no movement to traverse bar I5 until the latter has moved far enough to contact the opposite screw I5c.
Referring now to Figs. 5, 6 and '7, an alternative cam arrangement is shown for the main cam drive. The upper end of shaft 33, carrying the one-way clutches 35, is fitted with a bevel wheel 49 meshing with a similar wheel 55: on a horizontal shaft 5I. Such shaft also carries a barrel cam 52, in, the groove 53 of which is a roller 53a carried from a sliding bar which, in turn, is mounted in the brackets Lever arm 25 connects to this sliding bar with a pin and slot connection at 55. The roller 5311 and cam groove 53 are tapered, and by means of a set screw 5'5 the roller may be advanced into the groove, when required, to take up wear,
Whilst, in the example shown, there are three rods 38 for imparting motion to the main cam, there may be two only, or there may be more than three.
