24 Claims. (Cl, 19-459) This invention relates to an improved coiler machine for laying stock or sliver from a carding, drawing, combing or other machine into a container for transporting to another machine for further processing.

in the textile industry, coiler machines are driven from power talce-oifs on a carding, drawing, combing or other machine from which a sliver is being drawn. The power take-offs from the carding or other machines are invariably provided with shafts at 90 degrees to the direction of passage of the cotton sliver feeding from the machine, the direction to the take-off being right or left depending on how the carding machine or other source of sliver is to be arranged with respect to the aisle space in the mill. Many of the existing power takeoffs in textile mills were originally installed for driving coiler units utilizing cans of relatively small diameter with the result that such power take-off shafts were mounted quite close to the frame of the machine. As a result of these varying conditions, it is frequently necessary to modify existing power take-offs when installing coiler units.

A further problem in connection with the installation of coiler machines is the fact that there is a wide diversity of opinion in the textile industry as to which is the most suitable diameter for the can or container in which the sliver is packed. With coiler units of the prior art, once a choice is made as to the size of can to be accommodated by the coiler, it is either impractical or impossible to later convert to a different size can.

The wide diversity of physical requirements encountered in the installation of coilers, such as left and right hand power take-offs, power take-offs mounted close to the frame of the carding or other machine, and lack of uniformity of can diameters used in diiferent textile mills prevents standardization of coiler equipment and installations and also frequently results in inefiicient utilization of aisle space. l

Furthermore, most coiler machines of the prior art are relatively fixed in their characteristics, such as the speed ratio or" the coiler tube gear to the can table, or the positions of the coiler tube gear and can table relative to each other. As a result, coiler machines of the prior art cannot be adjusted to control the efficiency of the sliver pack in the can, or to make adjustments for providing optimum packing for varying diameters of sliver or varying can diameters.

It is an object of this invention to provide a coiler machine for use in textile mills which is universal in its application and which is adapted to be driven from existing power talte-otfs without modification of the takeoff.

It is another object of this invention to provide a coiler machine which is adjustable to improve the efficiency of the pack of the sliver in the container.

it is still another object of this invention to provide a coiler machine which is easily adaptable to receive 2,832,099 Patented Apr. 29, 19558 ice containers of various diameters and also to adjust for laying slivers of different diameters.

It is a further object of this invention to provide a coiler machine in which the speed of the can table may be readily changed relative to the speed of the coiler tube gear.

it is a still further object of this invention to provide a coiler machine which may be readily adapted to either a 1eft-hand or right-hand power take-oif and in which the coiler may be mounted close to the frame of the carding machine or other machine from which the sliver is being drawn to conserve aisle space.

in achievement of these objectives, there is provided in. accordance with this invention a coiler including a hollow vertical column in which is positioned a vertical drive shaft adapted to be driven in geared engagement from the power take-off of a carding machine or the like. At the upper end of the vertical column, the coiler head is mounted and includes a stationary spectacle which supports a rotatable coiler tube gear driven by a gear on the vertical drive shaft. Calender rolls are also driven from the vertical shaft and feed the sliver to the rotating coiler tube. The entire head structure including the spectacle and rotatable tube gear is carried by a male plug member which is received by the upper end of the vertical column in such manner that the entire head assembly may be rotated through 360 degrees of movement with respect to the vertical column to provide angular adjustment of the head with respect to the vertical column. The rotating tube gear is supported by antifriction roller members which engage an inclined track surface on the inner periphery of the spectacle to sup port the rotating coiler tube gear with a minimum of friction.

The base of the coiler unit is also attached to a male plug member which is received in the lower end of the vertical column and permits the base to be rotated through an angle of 360 degrees with respect to the vertical colurnn to permit angular adjustment of the base with respect to the column. The base supports a rotatable can table which may be rotated in the same direction or in an opposite direction to the direction of rotation of thecoiler tube gear, depending upon the gearing arrangement used.

In one embodiment of the invention, the can table is rigidly secured, as by screws, to the upper surface of a worm gear which is in geared engagement with a worm driven from the lower end of the vertical drive shaft.

The worm gear to which the can table is attached is supported for rotation by three circumferentially spaced bearing member's mounted on a gear guard carried by the base, the can table being centered for rotation by a center bearing carried by the gear guard. The worm is keyed or splined on a worm shaft supported by the gear guard.

The gear guard which supports the worm and worm gear is supported on the base member and is adjustably movable with respect to the base member to permit changing the distance from the vertical column to the center of rotation of i the can table. This adjustment permits the coiler unit to receive different sizes of cans and also permits adjustment of the laying of the sliver into the can. The center bearing for the worm gear is also adjustable along the gear guard to permit different center distances between the worm and worm gear. This permits substitution of different worm gears having different numbers of teeth to thereby change the ratio of the worm gear to the worm, permitting a change in speed of the can table with respect to the rotating tube gear at the upper end of the coiler unit.

in amodiiied form of the invention, the can table is driven from the main vertical drive shaft through a chain drive connection instead of using a worm and worm gear drive as previously described. In this modified construction, the can table is secured by screws to the upper surface of a rotatable can table sprocket which in turn is supported for rotation by rollers carried by a chain guard member. The chain guard is adjustably mounted on the base to permit changing the distance of the center of retation of the can table from the vertical column. In the chain drive coiler unit, change in speed of the can table relative to the coiler gear tube is obtained by changing compound gearing which drives the chain sprocket.

Further objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings in which:

Referring now to the drawings and more particularly to Figs. l6, the coiler unit is generally indicated at 1t) and includes a hollow vertical column generally indicated at 12 having connected at its upper end a coiler head assembly generally indicated at 14 and having connected at its lower end a coiler base assembly generally indicated at 16 A vertical drive shaft 18 extends vertically for the entire height of hollow column 12 and projects above column 12 into the head assembly 14 and below column 12 into the base assembly 16. Shaft 18 is driven from a horizontal power takeoff shaft 2'0 which extends through an opening 22 in column 12 substantially at the midpoint of the height of the column 12. Shaft 2% is driven from a carding or other textile machine with which the coiler unit is being used. Shafts 29 and 13 are connected in driving relation to each other by means of a pair of mating beveled gears 24 and 26 on the respective shafts. At its upper end, vertical shaft 18 is provided with a beveled gear 28 which mates with a similar beveled gear 30 on a horizontally disposed calender roll shaft 32. At the radially outer end of calender roll shaft 32 is disposed one of a pair of conventional calender rollers 34' which feed sliver from a carding machine or the like to the coiler unit. The other calender roll shaft (not shown) is driven by a gear 35 (Fig. 1) mounted on shaft 22. A calender roll cover 36 which is pivotally supported with respect to the head assembly 14 covers the calender roll mechanism when in the position shown in Fig. l. Calender roll cover 36 is provided with a trumpet 38 through which the sliver is fed to calender rollers 34 from the carding or other textile machine, as is well known. I

Vertical drive shaft 18 is also provided adjacent its upperend but below beveled gear 28 with a horizontally disposed spur gear 40 which meshes with coiler tube gear 42 as will be described. At its lower end, shaft 18 has mounted thereon a beveled gear 44 which mates with a second beveled gear 46 carried on a horizontally disposed shaft 48 on which is mounted a worm 50 (Fig. 5)

which drives a worm wheel to thereby rotate the can table as will be described in more detail hereinafter. Shaft 18 is supported intermediate its height by a bearing 52 carried by column 12.

The head assembly 14 includes a horizontally disposed stationary spectacle 54 which surrounds and supports coiler gear 42. Spectacle 54 and the rest of the head assembly are supported by a plug member 58 which is rigidly secured to spectacle 54 and which extends downwardly into the upper end of vertical column 12. Plug and. the coiler head assembly carried thereby may be rotated in a horizontal plane through an angle of 360 degrees with respect to column 12 to permit positioning the head assembly 14 at any desired angular position with respect to column 12. A set screw 60 extends through the wall of column 12 and engages plug 58 to retain the plug and, consequently, head assembly 14 in any position to which they may have been adjusted with respect to column 12.

Coiler gear 42 is a disk-like member provided on its outer periphery with gear teeth 56 (Fig. 3) which mesh with the teeth of spur gear 40 on shaft 18. The engagement of teeth 56 of coiler gear 42 with the teeth of spur gear 40 causes the coiler gear to be rotated with respect to spectacle 54. A coiler gear spindle 62 is fixed to and extends upwardly from the center of the upper surface of coiler gear 42. A coiler tube 64 extends angularly through the upper end of spindle 62 to adjacent the outer pheriphcry of gear 42 where it communicates with a passage 66 in the coiler gear. The sliver which is being laid into the can C passes from the carding machine or other machine from which the sliver is being obtained, through trumpet 33, through calender rolls 34, through coiler tube 64 and passage 66 in coiler gear 42 and thence into container or can C.

A coiler gear cover generally indicated at 68 is also supported by and is stationary with respect to spectacle 54. Coiler gear cover 68 includes a hat top portion 70 which is centrally apertured at 72 to surround a circular enlargement 74 at the upper end of spindle 62 on coiler gear 42. Coiler gear cover 68 includes a downwardly extending cone-shaped portion 72 which extends downwardly from the radially outer extreme of top fiat portion 70 and which terminates in a vertical wall portion 74. The lower edge of wall portion 74 rests on a countersunk lip or ledge provided in the upper surface of spectacle 54. Coiler gear cover 68 is held in a downward position by a hold-down screw 75 which passes through the calender roll housing and seats on the upper surface of tube gear cover 68.

Extending inwardly from the vertical wall portion 74 of coiler gear cover 68 at suitable intervals are enlarged vertical wall portions 76 best seen in Fig. 3 which terminate at a height a short distance above the upper surface of the outer rim of tube gear 42. Roller members 78, which may be referred to as anti friction means, are supported for rotation in sockets provided in each of the inwardly extending wall portions 76, the lower surface of each of the rollers 78 riding the upper surface of the rim of tube gear 42. The rollers are vertically adjustable and are locked in place by means of a set screw 79 provided in the tube gear cover for locking each roller at the proper height after the desired clearance is obtained. Rollers 78 se ve as a hold-down means for gear 42. the rollers at the same time providing a rolling friction between stationary cover 68 and rotating tube gear 42.

Tube gear 42 is itself supported with respect to spectacle 54 by rollers 31), which may be referred to as antifriction means, which are carried by gear 42 at spaced intervals. For this purpose, gear 42 is provided at suitable intervals, such as l20degree intervals, for example, with radially outwardly inclined apertures, and rollers 80 are mounted on stub axles 82 which are inclined at a substantially -degree angle with respect to the horizontal plane of gear 42. Rollers 80 extend through the inclined apertures in the gear tube into rolling engement with the stationary spectacle. The spectacle is provided on its inner rim with an inclined surface as (Figs. 1, 2 and 3) which serves as a bearing for the rollers tit") and for the boiler gear 42. The bearing structure just described including the use of rollers 80 engaging spectacle d4 maintains the rotating tube gear concentric with the spectacle opening at all times and maintains a uniform annular clearance between the tube gear a. spectacle.

The se portion 16 of the coiler unit includes a base plate member so which extends in a horizontal plane and which is rigidly connected to a vertically extending plug member which is received in the lower end of vertical column 12:. Base 86 and the attached plug 83 may be rotated through an angle of 360 degrees with respect to column to provide any desired angular relaion of the base member to column 12. After base has been adjusted to the desired angular position, set ew h 'ch extend through the lower end of col tr. are tightened with respect to plug 88 to thereby hold base i) and plug 33 in the desired adjusted po sition. J icludes a circular ledge portion 95; on which the lo er end of column 12 rests. Shaft 43 on which worm is keyed or splined extends through a o Jtted opening 89 in plug 35. At its radially inner and shaft ll is supported within plug 88 by a yolre 91 which is angularly adjustable with respect to base 86 and plug Slot extends circumferentially for an arc sufrici to accommodate any regular movement of shaft i th respect to base 36 and plug 83 which occurs dot the radial adjustment of the gear guard to be hereinafter described.

The base assembly includes a gear guard member generally indicated at 94 and adjustahly positioned on base tie, a worm gear bfi supported by gear guard 94, and a can table t -d which is attached to and rotates with worm gear 955. As will best be seen in Fig. 6, gear guard M is generally circular disk-shaped member having a base portion 9' 8 which is apertured at its center as indicated at lilo and a vertical flange portion 102 which extends upwardly a short distance above the plane of The vertical flange portion 102 of gear guard 4 is provided at one of its portions with a bearing for the shaft 53 on which worm is removably splined or lteyed.

An important feature of the coiler construction is the fact that the position of gear guard 94, and hence the axis of rotation of can table 96, may be adjusted with slots in the base portion 98 of gear guard 94. Slots res extend in a direction radially with respect to column 12 to thereby permit gear guard 94 to be adjusted radially toward or away from column 12. When the nod spacing of gear guard 94 has been obtained ect to column 12, screws 1% are passed through of guard 9d and into apertures 110 in the surface of c s .v N to thereby hold gear guard in a hired position relative to base 86.

in other to permit the adjusting movement of gear guard 9 4 with respect to base 36 just described, worm may be loosened with respect to shaft 48 on which it is positioned by loosening set screw 112 (Fig. 5) which secures worm 5b to shaft 48. This permits a relative movement of worm with respect to shaft 48 while gear guard 94 is being adjusted relative to base 86. After the adjustment of gear j guard 94 has been completed, set screw 112; may then be tightened to again rigidly secure worm Fit to shaft 48. The provision of arcuate slot 39 in plug 88, previously mentioned, permits a limited angular movement of shaft 48 with rerespe t to vertical column 12 due to the provision of 6 spect to base 86 during the radial adjustment of gear guard 94. p

An adjustable bearing plate 114 is fastened to the base portion as of gear guard 94 for centering worm gear 95 which mates with worm 5t). Bearing plate 114 is provided at its diametrically opposite portions with slots 116 which preferably extend in a direction substantially perpendicular to the axis of bearing 104 for worm Silt. Bearing plate H4 is secured to gear guard 94 by screws lid which extend through slots 116 and into tilt provided in base portion 98 of the gear guard 94 and it is thus apparent that when gear guard 9 is adjusted radially toward or away from vertical column 12, hearing plate 114 is also adjusted "ally toward or away from vertical column 12. A hearing 122 (Fig. 6) is received in a central aperture of bearing plate littto receive the downwardly extendiag shaft or shank portion 124 of worm gear 95. The provision of the adjustable bearing plate 114 permits worm gears 95 of different diameters to be received within gear guard to mate with worm 50. This is due to the fact that the adjustable bearing plate 114 permits variation of the center distance of bearing 122 with respect to worm db, thereby permitting worm gears 95 of different diameters and having different numbers of teeth to be interchangeably received in mating relation to worm 50. This permits changing the ratio of worm gear with respect to worm St) to thereby vary the rate of rotation of worm gear 95 and consequently the rate of rotation of the can table carried by the gear. This is an important advantage since it permits changing the speed of rotation of can C to provide optimum speeds of rotation of the can for different diameters of sliver and diiferent diameters of cans.

Can table 9% is secured to worm gear 95 by three symmetrically arranged ilat head screws 126 which pass through countersunk apertures l2? in the can table and are received in drilled and screw'threaded holes 130 in worm gear 95'. The can table is a disk-like member having a base portion 132 and a plurality of circular ledges at its outer rim such as those indicated at 134 and 1336 which are successively positioned radially outwardly of each other and raised slightly above each other. The plurality of successively raised and radially displaced ledges 13 i and 136 permit the can table as to accommodate cans C of different diameters. Vertically extending plug 38 is recessed as indicated at 93 (Fig. 1) to receive the outer rim of can table 96 when the can table is at its radially innermost adjusted position.

Jan table 96 rotates with worm gear 95. Gear guard 94 has a plurality of circumferentially spaced roller members 99 (Figs. 4, 5, 6) which support the underneath surface of the can table with rolling or sliding friction. The load of the can table 96 and gear 95 is carried by rollers W rather than by the center bearing member. The center bearing serves only to locate the center of the worm gear 95 and hence the axis of rotation of can table 96. The rollers 99 used for supporting can table 96 with rolling friction can be replaced by buttons or bosses which would support the can table with sliding friction.

There is shown in Figs. 7, 8 and 9 a modified form of coiler unit having a modified type of base assembly which utilizes a chain drive for driving the rotatable can tabe instead of the worm and worm gear of the embodiment previously described.

Referring now to Pi s. 7, 8 and 9, the modified embodiment includes a hollow vertical column through which extends a vertical shaft 3152. A base assembly generally indicated at 154 includes a horizontal base portion 156 to which is connected a hollow vertical portion 158. Vertical portion 158 has an inwardly projecting annular flange 160 which serves as a bearing for the lower end of column 150. Base 154 including 7 portion 158 may be rotated through an angle of 360 degrees with respect to column 150 to provide any desired angular position of the base with respect to the column.

Rigidly fixed to the lower portion of shaft 152 where it projects into the base portion 158 is a gear 162 which meshes with a gear 164 carried at the upper end of a short vertically extending stub shaft 166 carried by base 156. Gear 164- is free to turn on shaft 166. A second gear 168 is rigidly attached to or integral with gear 164 below gear 164 and meshes with "it is freely rotatable on the lower portion of shaft 152 below gear 162. Gear 1711 has a hub portion 172 extending downwardly therefrom and a sprocket 174 is fixed to the lower end of hub 172 and turns with gear 170. The speed of rotation of sprocket 174 may be varied by substituting suitable combinations of

gears

162, 164, 168 and 170.

A chain 176 meshes with sprocket 17 1 to drive a can table sprocket 178. A chain guard 1811, which is a flat, generally disk-shaped member, is adjustably supported on the upper surface of horizontal base portion 156. Chain guard 1813 may be adjusted relative to base portion 156 due to the provision of V-shaped arcuate slots generally indicated at 182, 184 and 186 (Figs. 8 and 9). A screw 1S8 passes through each of the t -shaped

slots

182, 184 and 186 and into a fixed aperture in base portion 156. Each slot comprises an a arm and a b arm. Chain guard 180 may be adjusted radially with respect to the central vertical axis of column 156 by sliding chain guard 181) along base portion 15 to the desired position and then securing the chain guard to the base by means of screws 188 passing through the respective slots. The inclination of slots 1&2, 1354 and 186 is such 1,

that the same spacing is maintained between the vertical column and can C (Y distance in Figs. 8 and 9) and between the apron and can C (X distance in Figs. 8 and 9) for different sizes of cans, such as 14-, 15- or 16-inch diameter cans. the chain guard 180 is moved along the a arm of its slots, while for left-hand power take-offs, the chain guard is moved along the [2 arms of its slots.

Fig. 8 shows the position of the chain guard 1813 when a small can is supported by can table sprocket 178 and chain guard 1311. The chain guard has been moved inwardly until screws 138 are located at the apex of each Vwhaped slot 18.2, 1554, 136. In Fig. 9, the chain guard 18 has been moved along the a arms of the slots to accommodate a larger diameter can, the coiler unit being driven from a right-hand power take-off. It will be noted that the X and Y distances between the can and the card. apron and between the can and the vertical column remain the same for both small and large cans although, of course, the spacing between the axis of rotation of the can table and the vertical column is different for small and large cans.

Chain guard 180 has a bearing socket 190 which receives a hub or shaft 192 extending downwardly from the underneath surface of can table sprocket 173, to thereby support the can table sprocket for rotation. Can table 196 is rigidly attached to the upper surface of sprocket 178 by three symmetrically spaced screws 194. The load of can table 196 and sprocket 17$ is supported by rollers 198 carried by chain guard 18 1, thereby causing can table 1% to rotate with can table sprocket 178. In order to insure that chain 176 is maintained under constant tension in any of the various positions to which chain guard 1811 may be adjusted, a suitable spring-biased tensioning device of any suitable type is employed and is pivotally supported by base 154.

The can table support arrangement disclosed for use with the chain drive may also be used for the gear drive construction shown in Figs. 1-6. This is accom- For right-hand power take-eds,

plished by providing gear guard 94 with arcuate slots similar to the V-shaped

slots

182, 184, and 186 of Figs. 7 and 8. Suificient adjustability of the can table sup port for many purposes may be obtained using a nonswiveliug base but providing V-shaped slots such as 182, 134, and 186 to permit movement of the gear guard or sprocket guard relative to the base. In such case, the coiler head need not be adjustable through an angle of 360 degrees but should be angularly adjustable in a horizontal plane through an angle sufiicient to permit the coiler head to follow adjustments of the can table along the V-shaped slots.

It can be seen from the foregoing that there is provided in accordance with this invention a coiler unit which is adaptable for use under many varying conditions which may be encountered in different textile mills and is therefore of universal application. The head assembly and each of the base assemblies described are adjustably rotatable through an angle of 360 degrees with respect to the vertical column of the coiler unit to thereby permit adjustment of the head and base assemblies to meet varying installation conditions which may be encountered. For example, this permits the coiler unit to be adapted for use with either left-hand or right-hand power take-olfs from the carding machine or other textile machine with which the coiler unit is being used. Also, the head assembly is so constructed that the coiler tube gear of the head assembly is supported for rotation with a minimum of friction with respect to the stationary spectacle.

Also, the can table support for each of the coiler units is radially adjustable with respect to the vertical drive shaft column to permit the can table to be supported for rotation at ditferent radial distances from the vertical column. This is an important adjustment since it permits the can table to be shifted to better accommodate various diameters of cans and also to improve the quality of the pack of the sliver.

Furthermore, in the embodiment utilizing the worm and worm gear drive to the can table, the adjustability of the bearing for the worm gear with respect to the worm permits variation of the center distance between the worm and worm gear thereby permitting use of difierent size gears with the same worm. This permits a change in the speed ratio of the worm gear with respect to the worm to thereby obtain different rates of speed for varying diameters of sliver and for varying can diameters. This same speed adjustment can be made by changing the compound gearing which drives the chain sprocket in the other embodiment of the invention. The various adjustment features of the base permit adjustment of the base to obtain optimum conditions of laying of the sliver to thereby improve the quality of the pack of sliver in the can as Well as the weight of sliver which can be packed in a can of a given volume. Thus, the adjustability features of the coiler unit permit maximum efficiency of operation and also permit the coiler unit to be adapted to various physical conditions in the textile plant in which it is being used.

While there have been shown and described particular embodiments of the invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention and, therefore, it is aimed to cover all such changes and modifications as fall within the true spirit and scope of the invention.
