The present invention provides an improved textile apparatus for operating on sliver and which includes a gill box and sliver feed rolls which are located at the input and output ends of the gill box and effect feeding of the sliver. Certain features of the present invention are usable in a variety of different machine environments. However, as representing the preferred embodiment, a textile apparatus 10 is illustrated in the drawings.
The textile apparatus 10 includes a main frame or base 11 which supports a gill box 12, shown schematically in FIG. 1. The gill box 12 is of conventional construction and will not be described in detail in view of the Wellknown construction thereof. The textile apparatus, of course, operates on sliver which is advanced through the gill box 12 and feed rolls 13, 14 are supported by the Support frame 11 in advance of the gill box 12 at the input end thereof. The feed rolls 13, 14 function to advance the sliver.
Delivery or front draft rolls 16, 17 and 18 are located forwardly of the gill box 12 at the output end thereof and are driven at a speed preferably greater than the speed of rotation of the rolls 13, 14 in order to pull the sliver through the gill box and effect a drafting thereof, as is well known. The rolls 16, 17 are substantially the same size as shown in FIG. 1 and define a nip therebetween. A
draft roll 18 is a smaller roll which defines a nip with the roll 16. The sliver which is advanced through the apparatus is combed in the gill box by the faller bars therein, as are well known, in order to align the fibers forming the sliver and is delivered from the apparatus to a suitable balling head or container, not shown, which receives the sliver.
The distance between the nip defined by the rolls 13, 14 and the nip defined by the rolls 16, 17 may be varied depending upon the length of the fibers comprising the sliver being handled by the textile equipment. This distance between the nips of these rolls is commonly referred to as the reach or ratch of the textile machine. The various reasons for adjusting the distance between these rolls are well known, but primarily it is to facilitate the handling of the slivers having different length fibers.
As noted above, the textile apparatus 10 is constructed so as to permit adjustment of the ratch and specifically the rolls 16, 17 and 18 are supported for adjustment toward and away from the gill box 12 and toward and away from the rolls 13, 14 to effect the adjustment. The rolls 16, 17, and 18 are mounted at their opposite ends in supports 20, 21, respectively. The supports 20, 21 carry bearings which support the shafts of the rolls in order to provide for rotation of the rolls relative to the supports 20, 21. The supports 20, 21 are, in turn, secured by suitable fasteners 22, 23 to a support plate 24. The support plate 24 is secured by suitable fasteners 25 to the main frame 11 of the apparatus. The fasteners 25 are in the nature of a nut and bolt which are located in a slot 26 in the plate 24. The fasteners 25, since they do project through slots 26 in the plate 24, if loosened, permit movement of the plate 24 relative to the bolts. In this manner, the fasteners 25, when loosened, allow for movement of the support plate 24 relative to the main frame 11 of the apparatus.
Suitable mechanism is provided and generally designated 30 for effecting movement of the plate 24 and the rolls 16, 17 and 18 supported thereby relative to the gill box 12 and rolls 13, 14 of the textile apparatus. The mechanism 30 for effecting the movement of the plate 24 and, in turn, the movement of the rolls 16, 17, 18 comprises a pair of lever members 31, 32. The lever members 31, 32 carry rolls 33, 34, respectively, on the ends thereof (see FIG. 3). The rolls 33, 34 engage in slots 35, 36, respectively, in the plate 24. The levers 31, 32 are fixedly secured to a shaft 37 at spaced locations and which extends transversely to the direction of movement of the sliver and across the apparatus 10i. The shaft 37 is suitably supported at its opposite ends for rotation relative to the frame of apparatus 10. The shaft 37, upon rotation, of course, effects an oscillatory or a back-andfourth movement of the levers 31, 32 and the rolls carried on the outer ends thereof. Movement of the rolls in a back-and-fourth direction, of course, causes sliding movement of the support plate 24 relative to the base 11, thereby effecting movement of the draft rolls 16, 17, 18 of the apparatus 10, which, of course, effects an adjustment of the ratch as described hereinabove.
The shaft 37 is rotated in opposite directions in order to effect the back-and-forth movement of the levers 31, 32 by manual actuation of a handle 40. The handle 40 has a portion which projects inwardly through a slot, not shown, in the base 11 of the apparatus 10 and is fixedly connected to a block member 41 which, in turn, is xedly connected to the shaft 37. Downward movement of the handle 40, as shown in FIG. 4, effects a counterclockwise rotation of the block 41, as viewed in FIG. 4, and, in turn, a counterclockwise rotation of the shaft 37. Movement of the shaft 37 in a counterclockwise direction effects movement of the lever members 31, 32 in a counterclockwise direction, as viewed in FIG. 4, and effects adjustment of the plate 24 and the support for the rolls 16, 17, 18 in the direction indicated by the arrow 42 in FIG.
4. The 'rolls 33, 34 located in the openings 35, 36, respectively, move vertically in the openings when the shaft 37 is rotated.
When the handle 40 is in a down position, it may be moved upwardly manually. Such upward movement effects rotation of the shaft 37 in a clockwise direction, causing the levers 31, 32 likewise to be moved in a clockwise direction and effecting movement of the plate 24 and rolls toward the gill box in a direction opposite the direction of the arrow 42. The adjustment is effected upon loosening of the fasteners 25, and the rolls may be secured in their adjusted position upon securing of the fasteners 25 which clamp the plate 24 to the main frame 11 of the apparatus 10.
The adjustment or movement of the rolls 16, 17, 18 is effected Without requiring adjustment to the drive mechanism for driving the rolls. As shown in FIG. 2, the rolls 16, 17, 18 are driven from a drive shaft 50. The drive shaft 50 fixedly carries a driving gear 51. The driving gear 51 meshes with a driven gear 52 which is keyed to the shaft 53 for the roll 17 and thereby effects a positive drive of the roll 17. The roll 16 is driven by a pressure relationship between the rolls 16 and 17 and has no positive drive thereto. The roll 18 is driven from the gear 52. The gear 52 specifically has internal teeth 55 therein which mesh with a pinion gear 56 carried on the shaft 57 which supports the roll 18. Thus, the roll 18 is positively driven along with the roll 17. Suitable cover plates 58, 59 are secured to the supports 20, 21, respectively, and plate 24 and cover the open ends of the supports 20, 21 in order to provide for access to the bearings supporting the shafts of the rolls and for access to the gears, respectively.
From the above, it should be apparent that the gears 52 and 56 move toward and away from the gill box 12 upon adjustment of the rolls 16, 17, 18. This movement of the gear 52 is effected without interrupting the driving connection between the teeth on the gear 52 and the teeth on the gear 51 which mesh with the teeth on the gear 52. The adjustment is of a nature which effects merely the depth of the meshing of the teeth of these gears without interrupting the driving connection therebetween. Therefore, these gears are arranged so that there is no interruption of the drive to the rolls 16, 17, 18, even though the position of the rolls is adjusted and even though the driven gear 52 moves relative to the driving gear 51.
The textile apparatus 10 also includes an indicating mechanism, generally designated 60, which indicates the position of the rolls 16, 17, 18 relative to the rolls 13, 14, and thereby provides an indication of the length of the ratch for which the apparatus 10 is adjusted. The indicator provides an observer with an indication for determining that the apparatus 10 is properly adjusted. The operator may adjust the ratch to a particular length and can use the indicator in determining that the proper adjustment has been effected.
The indicator mechanism 60 includes a plate 61 having a graduated indicator scale 62 thereon. The plate 61 is secured to the support frame 11 of the apparatus by suitable fasteners in the form of nuts and bolts 63. An indicator needle 64 cooperates with the graduated scale 62 and is movable along the scale on movement of the rolls 16, 17, 18 and indicates the adjusted position of the rolls 16, 17, 18.
The needle 64 is moved along this scale 62 in response to movement of the handle 40 and, specifically, in response to rotation of the block 41 t0 which the handle 40 is connected. As best shown in FIGS. 5 and 7, a suitable mechanical connection, generally designated 70 is provided between the block 41 and the needle 64 in order to effect movement of the needle 64 in response to rotation of the block 41.
The mechanical connection 70 includes an elongated fastener member 71 which has a threaded portion 72 which is threaded into a threaded opening in the block 41 spaced from the axis of shaft 37. The fastener member 71 includes a shank portion 73 and an outer head 74. The
mechanical connection 70 also includes a yoke member 75 which has an opening 76 in one side thereof defined by a pair of yoke projections. The opening 76 slidably receives the shank portion 73 of the member 71. The yoke member 75 has a passage 77 therein and a setscrew 78. The passage 77 is adapted to receive the tip 79 of an elongated shaft member 80 which also forms a part of the mechanical connection 70. The tip 79 of the member 80 is received in the opening 77 and is secured therein by the setscrew 78.
The shaft member 80 has an enlarged shaft portion 81 which is received in the bore 82 of a flange or support member 83. The support member 83 has a plurality of openings 84 therein in a flange portion 85 thereof. The openings 84 are adapted to receive bolts which extend through the plate 61 and the support frame 11 of the apparatus in order to secure the support member 83 to the frame.
The outermost end portion 88 of the shaft portion 81 of the member 80 projects through the bore 82 in the support member 83 and through an opening in the support frame 11, and slightly beyond the plate 61. The portion 88 of the member 80 has a threaded opening 90 therein which is adapted to receive the threaded shank of a screw member 91. The screw member 91 extends through an opening in the needle 64 and is threaded into the opening 90 in the shaft 81.
From the above description, it should be apparent that upon movement of the handle 40, the needle 64 is moved along the scale 62 on the plate 61. With the mechanism shown in FIG. 6, downward movement of the handle 40 will effect a clockwise movement of the block 41 which, in turn, effects counterclockwise movement of the yoke member 75 about the axis of shaft 80. This results in the rotation of the shaft member 80 in a counterclockwise direction. Rotation of the shaft member 80 in a counterclockwise direction effects movement of the needle 64 along the scale 62 on the plate 61 in the direction of the arrow in FIG. 6. The amount of movement of the needle 64 along the scale 62 depends upon the amount of movement of the block 41. The location and position of the member 71 and its connection to the block 41 is such that a predetermined increment of movement of the block 41 will give a predetermined increment of movement to the needle 64. It should be apparent that movement of the handle 40 in an upward direction will effect movement of the needle in the reverse direction.
From the above, it should be apparent that the apparatus 10 includes a suitable mechanism for adjusting the ratch of the mechanism, that is, the distance between the rolls 13, 14 and the rolls 16, 17 on the opposite ends of the gill box 12. Moreover, the apparatus 10 includes an indicator means 60 which provides an indication as to the position of the rolls and which operates in response to movement of the rolls.
It should be further apparent that a detailed description of the preferred embodiment of the invention has been made hereinabove, and that certain modifications, changes, and adaptations may be made therein by those skilled in the art to which it relates, and it is intended hereby to cover all such modifications, changes, and adaptations Which come within the scope of the appended claims.
