Dec. 30, 1941. .w. SCHWEITER COP WINDING MACHINE Filed May 16, 1959 2 Sheets-Sheet 2 Patented Dec. 30, 1941 UNITED STATES PATENT OFFICE Application May 16, 1939, Serial No. 274,017 In Germany May 23, 1938 18 Claims.
This invention relates to cop winding machines in which the thread guide carries out the oscillating movement for the production of the cross winding and a control device is provided for the stepwise feeding of the thread guide according to the progress of the formation of the cop, said device being engaged and disengaged by a feeler bearing against the periphery of the bobbin.
The object of the invention is to provide an effective organization of this kind specially suited for full-automatic operation and for winding cops with a superior degree of uniformity, and affording various other advantages which will be herein made apparent.
An embodiment of the invention is illustrated by way of example in the accompanying drawings, in which:
Fig. 1 is a 'side elevation of a winding machine viewed in upward direction of Fig. 2, some of the parts being in longitudinal section,
Fig. 2 is a top plan view of Fig. 1,
Fig. 3 is a section through the thread guide carrier taken on line III-III of Fig. 1,
Fig. 4 is a side elevation viewed in downward direction of Fig. 2.
A spindle shaft I carrying at its front end a driver head 2, is journalled in a casing 3 and driven by a device not shown. The spindle shaft I carries a' worm wheel 4 which meshes with a worm wheel 5 and drives a cam cylinder 6 conneeted to the worm wheel 5. The cam cylinder 6 is keyed on a shaft 39 journalled in the casing 3. A fixed rod 7 is fastened to the casing 3 and carries on its front end a spindle or cop holder 8. This holder 8 carries a holder cup 3 which is rotatable in a sleeve 10, which sleeve is axially shiftable in the holder 8; The sleeve 10 bears displacement of this rod from the shaft l4 being adjustable by means of these nuts 2 I-24.
A thread guide carriage 25 is slidably mounted on the carrier rod 1 and has an arm 26 embracing the shaft I4 and. securing the carrier against rotation. A bolt 21 is rotatable in the thread guide carrier 25 and the thread guide 29 is fixed on the head 28 of this bolt 21. The bolt 21 carries on its lower end an arm 30 having a bifurcation 3| which embraces the swinging rod and is thus compelled to participatein the rocking movement of the rock shaft l4.
A bell crank lever 33 is oscillatable about a pin 32 on the thread guide carrier 25. A discshaped feeler 34 is rotatably mounted on the upwardly directed arm of lever 33 and secured by a lock ring 36 whereas the laterally directed arm of the lever 33 rests on a laterally movable rail against a compression spring H and can yield elastically when the winding spindle I2 is clamped between the driver head 2 and the cup 9. A pin I3 is fixed in sleeve ID on the one hand for pulling back the cup by hand for exchanging a bobbin and on the other hand for securing the sleeve l0 against rotation. The holder 8 has at its lower end a bearing l8 for a rock shaft [4. This shaft i4 which is also journalled in the casing 3, carries within the casing 3 a crank l5 on the free end of which a runner roller I6 is mounted rotatable about a pin l9. This runner roller l6 engages in a cam groove H in the cam cylinder 6 so that the shaft l4 carries out an oscillating movement corresponding to the shape of the cam groove IT. The ends of a rod 20 extend transversely through the shaft l4 and are secured 35. The rail 35 is disposed parallel to the path of movement of the thread guide carriage being fixed in levers 31 and 38 oscillatable about the carrier rod 1, the extended lever 38 carrying at one end a shiftable counterweight 40 secured in position by a set screw 49 and at the other end a set screw 4| with a lock nut 42. A lever 50 is oscillatable about a bolt 14 on the side of the casing 3 and oscillated by an eccentric pin 52 on the shaft 39. This lever 50 carries a feed arm 43 with a pawl 44 which cooperates with a ratchet wheel 45 rotatable about the stud 48 and rotates this wheel according to the oscillating movements of the lever 50. if the feed lever is not raised by the set screw 4|. A lever 59 pivoted on a stud 60 acts as a retaining pawl for the ratchet wheel 45 and looks it in one direction of rotation. The ratchet wheel 45 has a grooved drum 4! on which the cable 53 secured at one end to the ratchet wheel 45 is wound. This cable 53 extends from the hub 4'! around a pulley 54 mounted on the counter holder 8 to the thread guide carrier 25 to which it is clamped by a clamping screw 55 and a disc 56. The cable 53 passes from the thread guide carrier 25 around a guide pulley 51 mounted on the casing 3 and 5 then hangs down, carrying at its end a tensioning weight 58.
The device operates in the following manner:
The oscillating rod 20 which is actuated by the cam cylinder 6 through the intermediary of the lever l5 and the shaft l4, imparts an oscillating movement to the thread guide 29 through the intermediary of the bifurcated lever 30 and bolt 21 so that the running on thread BI is wound in cross winding on the rotating bobbin l2. The osin position by nuts 2|, 22, 23 and 24, the radial cillation of the thread guide is constant irrespective of the position of the thread guide carrier on the carrier rod 1, and is effected in exactly the same manner at the beginning as at the end of the winding process.
The length of the thread guide traverse can be varied as desired by changing the radial distance of the rod from the shaft [4 by means of the nuts -24.
In proportion to the formation of the winding bobbin the feeler 34 resting on the wound material yields in lateral direction depressing the sensitively balanced rail 35 and lever 38 with the result that the set screw 4! is moved downwards, so that the pawl 44 of the feed lever 43 can engage in the ratchet wheel 45 and rotate this wheel by several teeth. Thus, a portion of the cable 53 is wound on the grooved hub and the thread guide carrier secured to the cable is pulled forward a corresponding distance. During this movement the feeler 34 slides forwards on the conical portion of the winding bobbin 52 so that it moves at the same time nearer to the spindle I2. This movement causes the lifting of the rail 35 with the lever 38 and set screw 4|, which in turn raises the feed lever 43 so that the pawl 44 is no longer within the range of the ratchet wheel 45 and can no longer feed the same. As the bobbin 62 increases in size this whole feeding operation is repeated over and over again until the bobbin is finished. The rear conical formation of the bobbin is rendered possible by the fact that the rail 35 has at its rear end a shaper slope 53.
When the winding operation is terminated, the locking pawl 59 can be raised by hand or by a separate automatic device, so that the thread guide carrier is pulled back into its initial position under the action of the counterweight 58. With the aid of the counterweight 40 the feeler device can be set so that the feeler touches the winding bobbin very lightly and responds to every very small increase in size.
The adjusting screw ll intervenes between the end of the balanced lever 38 and the feed lever 43 and serves for adjusting the relation of the feeler to the carriage driving mechanism which enables the parts to be set with extreme sensitivity producing a smooth surfaced yarn mass on the cop, while the appropriate selection of the slope 53 for the rail 35 allows the contour of the wound mass, especially the base thereof, to be shaped as desired.
