12 claims. (onse- 115) This invention relates to vnew and useful improvements 2,810,245 Patented Oct. 2,2, 1957 in machines for inserting individual lengths of fibrous maare disclosed and claimed machines of this general type in which a strand of fibrous material such as cotton wadding is fed in individual lengths into the necks or tops of successively presented, continuously moved bottles. f

A machine constructed in accordance with this invention is an improvement over those disclosed and claimed 4 in the above patents, particularly with respect `tothe provisions for compacting the cotton in the necks of the containers by providing means includingreciprocable and oscillatable tucker fingers which act to lrotate the iny dividual strands of cotton and thereafter to push downwardly on the strands at various arcuate positions and thereby to effect a compacting and complete insertion of each strand. Improved means are also 'provided for preventing the feeding or parting of individual lengthsof brous material when no bottle is in position to receive them. f

It is, therefore, anvobject of this invention to provide a machine for the insertion of fibrous materials into partially filled bottles in which individual lengths are first separated from a continuously fed strand of fibrous material, then rotated slightly by tucker fingers to align the individual length with the major cross-sectional axis of a bottle, which ngersare thereafter effective to insert the strands into successively presented bottles and to compact the strands in the necks of the bottles by successive poking actions at various arcuate positions.y

Another object of this invention is to provide a machine of the character stated having a reciprocable and rotatable set of tucker fingers which are arranged to act in fixed and definite sequence to compact cotton into the necks of successively presented bottles.

A further object of this invention is to provide a machine of the character stated which is capable of continuo'usly inserting and compactly positioning individual cotton strands into the necks of successively presented bottles.

' A further object of this invention is to provide a machine of the character stated which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are lpointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and yspecific objects attained by its use, reference should be had tothe accompanying drawings and scribed a preferred embodiment of the invention.

. Fig. 17 isa fragmentary vertical section taken along the line 17-17 of Fig. 4; and

Fig. 18 is a fragmentary vertical section taken lalong the line 18-18 of Fig. 3. g h Referringtothe drawings in detail, the invention as illustrated is embodied in a single station machine for inserting individual lengths of fibrous strand into par# tially filled bottles and includes a base A, brous material and strand-separating and -feeding mechanism generally indicated at B, a turret assembly generally indicated at C and performing the material inserting operations, a driving mechanism generally indicated at D, an intake and discharge conveyor generally indicated at E and a container generally indicated at F which holds a Vsupply G of unbroken, stranded, fibrous material such as cotton.

The drive mechanisms include a motor 10 mounted on 'a base 12 which is adjustably positioned on one end of the turret C and is connected through a belt drive 14 and spiral gears 16 to a shaft 18. The rotative speed of the shaft 18 through the belt 14 maybe adjusted by varying the angular position of the base 12 through the use of a liandwheel 20 providedfor that purpose since the motor 10 is provided with .-a variable pitch drive pulley. The shaft 18 is mounted in suitable bearings on a lower spindle plate 22 and an upper spindle plate 24 which in turn are adjus-tably affixed to a main spindle 26 having its bottom portion threaded. The lower spindle plate 22 has a lower hub or sleeve portion which bears against a thrust bearing 28. The thrust bearing 28 is carried by the upper portion of a sleeve 30 which is threaded on the lower end of themain spindle 26 for vertical adjustment therealong.

A hollow shaft 32 having a lower Veccentric portion 33 isv positionedfto rotate around'the spindle 26 between the lower spindle plate 22 and the upper spindle plate 24 and is spaced kfrom the latter spindle plates by an upper washer 34 and a lower washer 36. The vertical position of the upper and lowerr spindle plates 22 and 24 and the hollow shaft 32 may be varied by adjusting the position of the sleeve 30 `on the yspindle 26. A cylinder cam 3:8,fhaving a central hub which is affixed to the Vhollow shaft 32 as by set screws and normally rotates therewith, is providedV with gear teeth around the lower periphery thereof which mesh ,withra driving gear 40 'affixed to the shaft 18. The shaft 18 is provided with a thrust bearing 42 positioned `@erogata alzare th 44 Sfcufed .t the 1.9A4 may be used to operate the up or adjustment purposes. eiflietlousalerudle platerzzgsxtends latera11n-and-route, wfdlyleyqadthe uprsrrindlePlateaaridlis prey 'de dz with suitable bearings to hold an indexings11,aft46;1f1fhe shaft 46 is indexed or rotated90j, atlinteryalsby means of `an eccentric pivot-arm and ratchet;farrangement.l This arrangement includes Kay strap 48 secured around the eccentric 33 ofthe hollow shaft 32 and connected to the medial portion of an arm A50 `.which in is pivoted4 at one end to a stud 51 fastened to the lower spindle plate 2,2:and pivotally connected at its other end to ODG end'of a link 52 havingits other end pivotally connected to allllbbed plate 54which is oscillatably mounted on `the upstanding hub ofa ratchet 60 keyed to the shaft 46 and is provided with a detent arm or pawl 6 which is biased inwardly toward the shaft 46 by a spring 58. The pawl 56 is arranged to engage ,one of four equally spaced teeth ,along the periphery of the ratchet 60. The `hubbed plate 54 is held in place by arnut 62` threadably engaged with the ratchet hub. The arm 50 is oscillated by the eccentric 33, resulting in reciprocation of the link 52 to cause the pawl 56 to engage one of the recesses on the ratchet` 60 and to index the shaft 46 through a90 arc during each 360 rotation of the eccentric. On the lower portion of the hubbed plate 60 is a friction-faced brake plate 64 which is biased upwardly by a spring 66, the tension on which may be increased or decreased by means of-an adjustably positioned nut 68 which is threaded on to the lower` portion of the hubbed plate `60. A friction washer 69 is interposed between the lower spindle plate 22 and the ratchet 60. The brake plate 64 and the ratchet 60, under the influence of the spring 66, together act as a brake Vto prevent rotation of the shaft 46 except when an indexing' movement is taking place.

Intake star wheels 70, 70 are rigidly affixed to the lower end of the shaft 46 and are provided with four bottle'- receiving pockets which receive bottles in succession from the conveyor E in operative association with the mechanism of the turret C. A circular disc 90 is secured to the` hereinafter to stop the feeding of cotton whenever there are no bottles being fed-to the star wheels.

The continuous strand of cotton wadding -is` adapted to be withdrawn from its container bythe feeding mecha-N nisms B which are carried by -and driven from `the depending hub of the ratchet 60. -For this purpose a large driving gear 76 is secured to the depending hub of theratchet 69 and meshes with a small pinion 78 which is freely .ro-

tatable about an upstanding stationary spindle 80 mount-` ed on a cover 82. A pentagonal plate 84 (see FigmS) having a suitable aperture to pass around the spindle 80 is secured beneath the lower lip of the cover 82.'r rIlhe spindle 80 also carries la gear 86 underlying thepinion78 which ispin-connected to the pinion in order to rotate therewith.

.The gear 86 meshes with a gear (not shownlmounted on the upper part of 4a vertical shaft 87 (see Fig. 5) journalled between pentagonal plate 84 and a lower rectangular plate 88. Another gear92V is mounted on Vtheupper part of the shaft 87 below the aforementioned gear. which is not shown on the drawings, and it meshes with a gear 94 of the same diameter mounted ,on a shaft 96a (see Fig. journalled in bearing blocks 96, 96 slidably carried in slots formed in the outer edges ofthe` plates 84' an'd 88.

A similar set of bearing blocks 96, 96 are carried in slotsA formed in the outer edges of the plates` 84 andV 88 in spaced parallel relation to the first set ofslotsi jTlre blolcks elower .Spindlqplatezl andvwith ahandwheel A dpttbasbaftlmhillz ine manually for start-` 96are yieldably retained in the slots by a yoke 98 and an v.slilltalblecmupression spring 100.`

A shaft (not shown) is Yjournalled in the rear set of the bearing blocks 96 and Visprovided at its upper end with `a gear 104 which is the same diameter as and meshes with a gear 106 xed on a shaft 108 journalled in bearings in the plates 84 and 88." 1;

A knurled` or fluted feed roll 110 is affixed to the` shaft 108 between the plates 84 and 88 and cooperates with a similar feed roll 112 aixed to a shaft (not shown). The rolls 110 and 112 constitute the rear pair of feed rolls and are intermittently stoppable, as will be hereinafter more fully described. Knurled or fluted feed rolls 92a and 94a are also affixed to the same shafts that carry the gears 92 and 94 as shown in Fig. 10. These rolls cooperate to constitute the forward pair of feed rolls and are continuously driven by the gear 86. The forward feed rolls are oriented with the rear feed rolls 110 and 112 to dischargecotton' tangentially to the star wheels 70, 70. s Means are provided tointermittently stoprotation. of the rear pair of feed rolls 110 :and 112 while permitting the forward pair to continue to rotate and thereby `to effect the parting or separating of individual lengths of cotton wadding from the strand lthereof solely through tension. vThese means include a freely mounted gear 114 which is rotated by the gear 86 and acts to `rotate the shaft 108 and gear 106 affixed thereto beneath the gear 114 through the medium of friction washers 118 and 120 a clutch mechanism. The clutch mechanism includes a hubbed driving plate 122 which is biased downwardly by a spring 124 secured to theshaft 108-by a bolt 126 and washer 128. The

' driving plate 122 exertsdownward pressure through a friction washer 130, gear 114 and friction washer 118 to rotate the shaft 108 and thereby the gear 106 which meshes with gear 104 so as to cause rotation of the rear feed rolls 110 and 112.` The parting of the cotton into individual lengths will be effected by lifting the driving plate 122 a distance sufficient to relieve driving pressure onthe washers and gears therebelow so as to cause the rear feed rolls to stop while the forward feed rolls pull the cotton apart. To disengage and stop the driving plate v 122 there is provided a friction washer 132 and a hub friction disc 134 which are cam-controlled. ,f

A cam generally indicated at 136 regulates the position of the driving plate 122. The cam acts througha mcchanism including an; arm 138 provided at its inneryend "T" with a hubw140 whichjis pivotally carried by anupstandingstud 141. `The outer end of the arm 138 is provided with an upstanding boss 142 which comprises an-upwardly extending roller cam follower 144. Another arm.`

146 rigidly `connected to the arm 138 through the medium o f the hub and extending in a generally opposite direction therefrom is provided at its outer end witha transversely disposed pin or stud 148 threadably en-k gaged therewith and having a flat outer end adapted to exert pressure upon a ball secured to a depending arm 150 of a bell crank 152. The bell crank 152 is pivoted on a shaft 153 held in place on a mounting aixed to the upper end of the stud 141. The other arm of the bell crank 152 comprises a yoke which spans the hub of the friction disc 122 and engages the underside of the disc portion thereof. 152 extends across a pair of fiats (not shown) on the friction disc so as to prevent rotation thereof during the periods when the rear feed rolls 110 and 112 are stopped.

y In the driving position the driving plate 122 is down and the cam follower 144 rides around the cam 136 on the low portion thereof. When a high spot is reached the cam follower is moved out and through the medium ofthe arms 138 and 146, the stud 148 and the bell crank 152', and causes the friction disc 134 and the friction washer 132 to bear against the clutch drive plate 122 to move it .upwardly along the shaft108 and thereby stop The yoke portion of the bell crank` its rotation and the rotation of the gear 106, the latter no longer being held tightly by the washers 118 and 120. It will be noted that the drive plate 122 is drive-connected tov the shaft 108 through the medium of a keyway and ball keys indicated at 154'which permit axial movement of the driving plate along its associated shaft. The gear 114 will then be permitted to rotate freely between the washers 130 and 118 without driving the gears 106 and 104 and the associated feed rolls 110 and 112. The cam 136, shown in detail in Fig. 8, comprises an arrangement of three discs, each having equal high, medium and low peripheral arcs which may be rotated with respect to each other to change the effective contour over which the follower 144 will travel. ln addition, a disc 156 is provided to block out the low portions of the cam when no bottles are being fed through the machine so as to completely cease the operation of the rear feed rolls and thereby to stop the feeding of the cotton.

The disc 156 carries a stud 158 ball-joint connected to one end of a link 160 the other end of which is pivotally connected to an arm 162 affixed to a square-shanked rock shaft 164. A spring 166 is connected to an arm 168 mounted o-n the square-shanked rock shaft 164. An arm 170 is slidably carried by the rock shaft and is pivotally connected to one end of a link 171 having its other end connected to a stud 173 which has its upper end pivotally connected to the half annular ring 72 and its lower end extending through an enlarged aperture 173a formed in the underlying plate (see Fig. 17). One end of the half annular ring 72 normally is positioned adjacent tlie bottles feeding along the conveyor E to the star wheel 70. When no bottles are present, however, the half annular ring 72 is caused by the action of the spring 166 and the arm 170 to move toward guide rails 172. This in turn causes movement of the link 160 which results in the positioning of the disc 156 so as to present only a high portion of travel for the cam follower.

The cotton leaving the forward feed rolls comes into operative association with mechanism carried by the turret C for rotating the cotton 90 and then inserting it into the necks of bottles presented therebeneath by the movement of the star wheel 70 and compacting the cotton therein through successive reciprocating and oscillating movements. The cotton exiting from the forward feed rolls comes against an angular stop 174 supported on a plate 175 secured to the plate 84. The stop is constructed to deflect the cotton to one side so as to initiate its rotation of 90. A counterweight 176 is secured by a link 178 which is clamped to a stud 180 projecting below the turret C. Another arm 182 extends from the counter-L weight to the cover 82 and may be adjustably positioned so as to move the counterweight 176 to balance the feeding mechanism which is supported by the shaft '46.

In accordance with the invention there is provided a pair of tucker fingers 184 which depend from the bottom of a cylindrical sleeve 186 journalled between the upper and lower spindle plates 24 and 22. The sleeve 186 is provided with a cross-head 188 having a projecting portion which terminates in a roller follower 190. The follower 190 engages the cylinder cam 38 to effect reciprocation of the sleeve 186. The cross-head 188 is provided with a thrust bearing 191 on the upper portion thereof which surrounds the sleeve 186 and carries the thrust of a bearing collar 192 positioned thereabove and affixed to the sleeve 186. The cross-head 188 is urged downwardly by a pair of springs 194 which are carried on a pair of spindles or rods 195 which extend through each arm of the cross-head 188 and are secured to the upper spindle plate 24 and extend downwardly through the lower spindle plate 22. The springs 194 bias the cross-head downwardly to maintain the roller follower 190 in contact with the cylinder cam 38. A bracket 196 is fastened to the top side of the spindle plate 24 and is provided with a vertical rod 198 which extends downwardly therefrom into the inside of the sleeve 186. The lower end of the rod 198 is provided with a cylindrical plug which forms an abutment for the upper end of a compression spring 200 which is carried withinI the sleeve 186 in order to bias the sleeve downwardly and urge the bearing collar 192 into contact with the thrust bearing 191 of the cross-head 188. Thus the sleeve 186 may be urged upwardly independently of the position of the cam follower 190 on the cam 136 whenever sufficient resistance is encountered to overcome the tension on the spring 200.

Means are also provided to oscillate the sleeve 186 through definite angular movements. These means include a cam 202 which is affixed to a hub 204 which is secured to the sleeve 32. The cam actuates a roller follower 206 which is fastened to the mid-portion of an arm 208. The arm 208 is fastened at its inner end to a vertical rock shaft and is provided at its other end with a gear sector 209 which meshes with a relatively thick gear 210 rotatably mounted on one of the spindles 195 which in turn meshes with a pinion 212 affixed to the sleeve 186. The arm 208 is biased so that the cam follower 206 is maintained in contact with the cam 202 by means of a spring 214 fastened to an arm 216 which is fixed to the arm 20S at its pivotal'point.

The operation of the tucker fingers under the influence of the cam 38 and the cam 202 results in the reciprocation and oscillation of the tucker ngers 184 as shown by Figs. 10 to 15. Cotton leaving the forward feed rolls is deflected to one side by the stop 174 as it becomes supported on the plate 175, and as the mid point of the cotton strand llength moves into registry beneath the tucker fingers 184 the fingers move downwardly to engage the cotton and to bodily rotate it clockwise This 90 rotation is necessary to lbring the longitudinal'axis of the cotton strand into'alignment with the major cross-sectional axis of the container. In `this position the cotton is centered over a hole provided therefor in the plate 175. The tucker fingers move downwardly under the infiuence of the cam 38 tol effect an initial tucking of the cotton (see Fig. 12). The fingers then move upwardly and under the influence of the cam 38 are rotated45 counterclockwise. A further ing action is then effected by the action of the cam 38. Thefingers again move upwardly and are then rotated 90 clockwise under the influence of the cam 202 followed by another ing action. The tucking fingers then move upwardly and are then returned to the starting position by bein-g rotated counterclockwise to complete one full cycle.

It is, of course, to be understood that various details of arrangements and proportions of parts may be modified within the scope of the appended claims.
