DEVICE TO DETERMINE SIZE OF YARN PACKAGES.
Application led September 21, 1926. Serial No. 136,751.
r1`his invention pertains -to machines such as Winders, spoolers, twisters, coners, tubes, and other machines in which yarn or thread is Wound into packages.
In such apparatus the package is usually formed by winding the yarn on a spool. For trade purposes it is desirable to have the packages of predetermined uniform dimen sions.
Heretofore it has been customary to rely on the operator or attendant to determine by observation when each spool has been Wound tothe proper diameter but the results have never been satisfactory. The attendant has a great number, sometimes hundreds, of spindles under his charge and it is impossible for `him to stop each one at exactly the right instant. The result has been that the packages are not uniform, Which often causes trouble in subsequent operations, such as packing.
Also, it has not been possible to furnish a number of packages each containing the same number of yards of yarn. Also, the present methods do not permit the operation of the machines to their full capacity because so much time is lost on account of the inability of the operator to be in more than one place at once.
Various devices have been devised 1n the effort to mechanically limit the size of such packages to desired dimensions, but they have not been successful. Some of them have had arms or fingers constantly in contact with the yarn or thread, either before or after it is wound, which is often injurious to the yarn.
Other devices have been Worked out to snub the yarn when it reached a certain o point. Such devices are only practical on fine, easily broken threads but are not practical on material which offers any appreciable resistance to rupture.
The object of my invention is to provide a device which overcomes all the above objections, which is entirely out of contact with the yarn until the package has acquired and which cuts the yarn or thread When `that diameter is reached, instead of rupturing the yarn by snubbing it. My device is equally effective on fine delicate yarn or on heavy coarse threads.
Another object is to provide a device Which is easily adjustable for packages or spools of different diameters.
Further and other objects and advantages Will be hereinafter set forth in the accompanying specification and claims, and shown in lthe drawings, Which'by Way of` illustration show what is now considered to be the preferred embodiment of the invention.
Fig. 1 is a side view of the device in operatlve position on the machine.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is an enlarged view of the front of the device.
Fig. 4 isa plan view of the device, showing in full lines the normal position of parts, and showing in broken lines the parts in moved position. i
Fig. 5fis an enlarged view of the head of the device, taken from the side.
Referring-to Figs. 1 and 2, 10 is a fixed art of the frame of a machine such for instance as' a spooler. 12 is a spool upon vWhich is being Wound the thread or yarn 111 to form the package which it is desired to limit to a predetermined size or diameter.
Spool 12 is mounted on a spindle 16, to which is fast a pulley 18 driven by a belt 20, in a counterclockvvise direction (Fig. 2).
The thread guide rod 22 is raised and lowered kby the vertically reciprocating lifter rods 24. Fast to guide rod 22 is the thread guide 26. A tension device 2S is provided to maintain uniform tension in the yarn.
In operation, spindle 16 rotates spool 12 in the direction of the arrow, thus drawing thread 14 from the source of supply through tension device 28. Guide rod 22 at the same time reciprocates vertically to cause the thread to Wind evenly from one end of the spool to the other.
y All the above described mechanism is old and Well known. It has been described simply to make perfectly clear the operation of the present invention which Will now be described.
Attached to frame 10-is a fitting 30. This fitting is provided with a slot 32, through 'which passes locking holt 34%. The slot profi indicated in Fig. 3,
rises beyond that point the thread will beV vides a means for adjusting the device lengthwise ot' the machine.
Arising from Htting and tast thereto is the vertical bracket lti. Pivotally mounted at the upper end ot bracket 3G, on vertical pin 38, is the laterally extending blade 40, provided with two ears 42 `through which passes the pivot pin 3S.U The saine end of blade IO is bent to form angle piece il to which is fastened one end ot coil spring (5 the purpose ot whichfwill later appear.
Mounted ,on the iront of plate is a somewhat similar plate 50, provided with a tail piece 5:2 which passes through slot 54 in plate i0. The tree end of 52 rests againstthe inner end of adjusting screw 5l thread ed through bracket 36.
Plates i0 and 50 are held together by stud 56 which passes snuglyy through a hole in plate and through a slot 5,8 (Fig. 3) in plate 40. This arrangement permits plates 40 and 50 to slide horizontally relatively to each other. To the front end of stud 56 is attached the'other end of spring 4G."
The free 4ends of plates 4() and 50 are notched to Aform a narrow V shaped slot (i0 when the plates are in normal position as in Fig. 3. The lower portion oi the notch in plate 40 is shaped as at 62 to connect one Vside of slot to the bottom outer corner of plate 40.
With the above description in mind the operation of the device will be readily understood.
The device is `located by means of slot 32 so that whenthe package or spool has attained the desired diameter, thread it contacts with the outer end of blade 40. This will be understood from Fig. 2, from which it will be seen that after one more wrap has been added to the package, contact will take, place. This contact limits the size ot' the package, as will be seen.
Dueto the action'ot' guide rod 22, the yarn 14 constantly traverses the spool l2 vertically from end to end. vWhen the winding on the spool reaches aV predetermined diameter, the thread, while passing upwardly, will contact with the under side ot surface `G2 as and as guide rod 22 guided by surface 62 into slot 60 wherein the thread wedges. After the thread is wedged in slot G0, the continued rotation ot spool 12 swings plates 40 and 5() trom normal position, indicated by lines in Fig. 4, towards the position indicated byy broken lines'in that same figure. It will be noted that the blades 40 and 50 swing about different centers, plate 40 swinging Iabout pin 38 and plate 50 swinging about the outer end of tail piece 52. This means'that plate 50 slides outwardly with reference to plate 40 as shown in the broken lines in Fig. 4,
thereby causing a shearing action at slot 60 and cutting the thread.
In actual service the action of the device is practically instantaneous after the'thread contacts with surface (52, anditcuts large strong threads as readily as fine delicate yarns.
In practice it is customary to slightly Vbevelthe cuttingiedgesat slot (30, but that is not necessary. The width of slot (SO may be regulated by means oi screw al which moves` plate 5() relatively to plate 40.
'-lhe amount of movement of `the plates relatively to eachother is limited by the lengthfof slot 58.
