Patented Dec. 30, 1941 FULL AUTOMATIC COP WINDING MACHINE Walter Schweiter, Horgen, Switzerland Application March 21, 1939, Serial No. 263,275 I In Germany June 23, 1938 22 Claims.
This invention relates to cop winding machines of the type in which the full bobbins are replaced by empty bobbins entirely automatically at the end of the winding operation.
More particularly it relates to such a machine in which for each winding spindle there is a complete set of automatic actuating members having their own power shaft and preferably contained in a closed box or casing, individual to each spindle, serving as the machine frame therefor. The invention consists, among other things, of improved means for clamping the cops in the winding position and rotating and stopping them in such position and releasing them, all with the least possible delay and so as to increase thereby the productive rate of the machine as hereinbelow pointed out in connection with the exemplification shown in the accompanying drawings wherein Fig. 1 shows the gear box in longitudinal section along the main driving shaft,
Fig. 2 is a top plan view of Fig. 1,
Fig. 3 is a longitudinal section taken along the winding spindle,
Fig. 4 shows partly in elevation and partly in section a safety device against too high resistances,
Fig. 5 shows partly in side elevation and partly in longitudinal section a gear box with starting device and individual drive.
Fig. 6 shows a plan with power shaft removed to show the underlying mechanism.
A driving shaft l, journalled in bearings 3 and 4 in a gear box 2 so that it can rotate and at the same time be axially shifted a few millimetres, carries on its outer end a friction disc 5 driven by a friction wheel 6 keyed on a driving shaft 1 common for several spindles. The frictional pressure necessary for effecting the drive is produced by a spring 8 which bears at one end against a collar 9 on shaft I and at its other end against a race ring in of a thrust ball bearing II which in turn bears against a grooved ring I2. A clutch fork l3 engages in the groove l2a of the grooved ring l2 and is keyed on an axle l5 rigidly connected to an engagement lever 14. A pull spring I1 is attached at one end to the rear end l6 of the engagement lever M (Fig. 5) and at its other end to a pin 33 fixed in the box 2, and tends to pull the clutch lever into its disengaged position.
In the disengaged position the grooved ring l2 bears against the worm l8 keyed on the driving shaft l and, through the pull exerted by the spring l1, presses forward the shaft l with the intermediary of a multiple disc clutch 25, which result that the friction disc 5 is no longer in contact with the driving wheel 6; consequently the apparatus comes to a standstill.
If the engagement lever I4 is pressed downwards by hand, the clutch fork I3 pushes the grooved ring l2 towards the rear so that the friction disc 5 is pressed against the driving wheel 6 by the spring 8 now becoming operative and starts up the shaft l and consequently the whole gear.
The engagement lever I4 is held in its engaged position by an adjustable stop l9 fixed on it, which stop bears against a crescent-shaped projection 20 on a strap 2| oscillatably mounted in the box 2.
A resilient thread guide 22 is fixed at one end on the strap 2i and carries at its other end a guide roller 23 over which the thread 26 runs. Owing to the pull exerted by the thread 24 the strap 2! is held in the position illustrated in Figs.-
1 and 5. If the thread breaks the strap 2| swings downward under the action of gravity so that by turning the crescent-shaped projection 20, the stop I9 is liberated and the engagement lever l4 pulled into its disengaged position by the spring H.
A compound worm andspur gear, 26-21, is mounted rotatably on the shaft l and is axially shlftable thereon by cam connections presently described. It is driven by this shaft through the comprises, in known manner, alternate disc members keyed at 3! to the driving shaft I and -intervening disc members keyed to finger extensions 30 on the worm 26. The discs are pressed together to produce the necessary friction between the compound gear and the end of the worm i8 which latter is fast to the driving shaft i. The worm 26, through the intermediary of a worm wheel 23 on a suitable countershaft, drives the drum cam 29 which imparts the oscillating movement to the thread guide (not shown on the drawings) through which the thread is guided while it is being wound onthe cop. The spur gear 2l drives a spur gear 34 fast on the spindle 34a of the bobbin-driving head 35, which spindle is mounted in a bearing sleeve 36 axially shiftable in the box 2.
The worm l8 drives a spur gear 40 through the intermediary of a compound gear 31, 38, rotatably mounted on a rock shaft 39 which is journalled in the box 2. This spur gear 40 is free on another counter-shaft, herein called the control shaft, 4|, and carries a plurality of studs or catch-pins 42. A disc 43 (Fig. 2) is keyed on the control shaft 4|, and carries a dog 45 pivoted thereon at 44 and pressed inwards by a spring 45. The dog is adapted to make connection with one of the pins 42 in order that the gear 40 may drive the control shaft 4|. A lever 41 outside of the box 2, is keyed on the end of rock'shaft 39 and is operated by a rod 48 which, at the finish of the winding operation, is actuated by the travon the rock shaft 39 to release the dog 45 so that it hooks onto the next pin 42 arriving under it, and thereupon the spur gear 40, disc 43 and control counter-shaft 4| rotate as a unit for one complete revolution. In the meantime the pawl 49 will have been restored to its initial position by the return of the thread-guide rod 48 so that it is encountered by the projection 59 on the dog 45 and the latter is then automatically disengagdd from the pin 42 and thecontrol shaft comes to rest. Thus when the control shaft has once been started it must continue its motion until it has made one complete revolution. This arrangement is known as a single-cycling mechanism and will be herein referred to as such. The shaft 39 is the starter shaft.
' Disc cams 5| and 52 are mounted fast on the control shaft 4| for actuating the mechanism for the bobbin change, cam 5| being for controlling the clutch 25, and cam 52 for reciprocating the bearing sleeve 36 of bobbin drive head so as to release the full bobbin and engage the succeeding empty bobbin according to the understood cycle of these machines.
A control lever 93 mounted to rock on the shaft 39, has one arm 53 engaged to the cam 5| while the other arm has a head 54 loosely connected to a rod 59 (Fig. 2). The desired relationship between the lever 93 and rod 59 is maintained by nuts. 5E51, yoke 55 and spring 58. The rod 59 is connected to a lever 60 which is pivoted at 5| in the box 2, said lever 60 having a pin 52 on which a roller 63 (Fig. 1) is rotatably mounted. This roller occupies the annular groove 54 of the compound worm-gear 26-21. A pull spring 12 anchored at 13 inside the box 2 and having its.
other end attached to the lever 93, pulls the camfollower 53 against the cam 5|.
Another control lever 94 also mounted to rock on the shaft 39 (see Fig. 3), has a cam follower arm 65 engaging the cam 52 and a head 55 on its other arm connected to-a rod 10. The desired relationship between the lever 94 and rod 10 is maintained by the nuts 68-49 and the member 51. The rod 10 is connected to a post 1| on the sleeve 36. A pull spring 14 anchored at 13 inside the box 2, with its other end attached to the lever 94, puls the cam follower 55 against the cam 52.
The top of the box 2 is entirely covered by a lid (not shown in the drawings) making the gear box dust-tight and capable of holding lubricant to be splashed on the gearing, It is pointed out that the parts which revolve at the high speed required for winding are disposed in the upper part of the casing where they can be above the level of any oil therein, and that the slower moving parts, such as the single-cycling mechanism and read guide cam, are in the lower part where they can splash ofl onto the upper parts thereby affording adequate lubrication for indefinite periods without foaming the oil.
In starting up the winder the hand lever i4 is depressed and through the intermediary of the clutch fork l3, grooved ring l2, thrust bearings |0--| pressure spring 8, the driving shaft is shifted axially, pressing the friction disc'5 into driving contact with the friction disc 6 on the power shaft 1, thus causing the driving shaft to rotate. The hand lever I4 is held depressed by the locking device |920 (Fig. 5) under the control of the stop motion. If the thread breaks, the stop I9 will be disengaged from the projection 20 of the member 2| so that the hand lever 4 is rocked by the spring |1 causing the clutch fork i3 to pull the friction wheel 5 away from its driving wheel 5.
In the automatic operation of the apparatus and at the point-when the cop is full and ready to be replaced by an empty cop, the rod 48 is pulled forward (to the left in Fig. 1 by a part of the thread-guide system not shown), and this rod by means of the lever 41 rocks the pawl 49 clear of the projection 59 of the dog pivotally secured to the disc 43. Under the action of the spring 46 the dog 45 snaps inward and becomes engaged by one of the pins 42 on the constantly rotating gear 40 and thereby the control shaft 41 is set in motion. By the rotation of the control shaft 4| the cam 5| causes the compound worm-gear 26-21 to be shifted towards the left (Fig. 1) by the lever 93 and connecting rod 59, thus separating the discs 25 and disconnecting the drive between the driving shaft and the compound gear 26, 21, which gear is pushed so far to the left that the conical extension 15 at its end engages the conical recess 16 in the fixed bearing 3, which acts as a brake, with the result that rotation of the compound gear 25-41, thread guide traverse cam 29 and the driver head 35 is stopped. When the driver head 35 or winding-spindle comes to a standstill, it is retracted (to the right in Fig. 3) by the rod 10, lever 94 and disc cam 52, thus allowing the cop 11 to drop by gravity into a chute not shown in the drawings. It will be understood that other cams are also mounted on the control shaft 4| to carry out the other functions necessary for the automatic bobbin change but these are not shown in the drawings as they do not form part of the invention.
When the empty cop has been brought into place, the driver head 35 is pushed forward by cam 52 to clamp it, after which the worm-gear combination 25-41 is pulled back until the clutch 25 again drives the winding spindle and thread-guide drum cam 29. Thereupon the control shaft 4| will have made a complete revolution and the nose 50 of the dog 45 coming into contact with the pawl 49 disengages the dog 45 from the pin 42 on wheel 40 with the result that the rotation of the control shaft H is stopped.
It may be noted that the compound gear 26, 21,
constitutes a coupling member which is intermittently operated to transmit the drive to the winding'spindle and interrupt such drive and stop the spindle and further, that the starting of the spindle is without shock because the driving connection is made through a friction clutch (25) closed by the resilient pressure afforded by the spring (58) in the cam-operated connections, thereby shortening this part of the cycle.
Fig. 4 shows a safety device which can be used for preventing breakage of any of the operating elements by excessive resistance in the event of the control shaft 41 being overloaded. Two collars 19 and 80 are fixed to the driving shaft l, the collar 19 having a dog 18 which enters a slot cut in the forward end of the worm l8. The worm in this form is free on the shaft but is held in driving contact with the collar 19 by the spring 8|. If the control shaft 4| is acoidentalw 1y overloaded, the resistance of the wheel 31 will be so great that the reaction on the worm will overcome the pressure of the spring 8| so that the worm will be declutched from the collar 19. The control shaft 4| and the compound gear 25-41 will then come to a standstill until the overload on the control shaft is removed.
Fig. 5 shows another method of driving the power shaft I which consists of a motor 82 directly coupled to the shaft 1. With this method the driving shaft I is not axially shiftable in the box 2. The apparatus or unit is started and stopped by means of a switch 84, through which electric current is supplied to the motor 82, being actuated by a link mechanism 83 connected to the hand lever M.
