SLIVER COILER Filed June 25, 1958 INVENTOR. 0L AN RICHARDSON 4 CHARLES m w TER BY m ATTORN United States Patent 2,916,180. suvna contra Olan Richardson, Hampton, audCharles' W.-Walter, Y Griffin, Ga., assignors to Southern States Equipment Corporation, a corporation of Georgia Application June 25, 1958,'Serial No. 744,510
13 Claims. c1. 19-159 This invention relates to sliver coilers and more particularly to coilers using largecan's provided: with rollers or the like to facilitate bodily movement of the cans and their contents from one position to another.
It is customary to move sliver cans from place to place as a routine procedure in textilemills; Frequently the cans are moved manually by an operator who simply slides the cans along the floor in groups of five or. six cans. The trend toward cans of larger and larger diameters results in substantial increases in the weight of the cans, particularly when filled with sliver. Thus with heavier cans to handle, it is becoming more and more difiicult for an operator to move the cans about, especially where a particular operation requires him to slide a group of several cans along the floor; In some instances it is necessary for the operator to reduce the number of cans moved simultaneously in a group and by so doing partially to defeat the purpose of using larger cans.
A principal object of this invention is to provide an improved coiler having a can mounted on rollers and having a platform arranged to receive a'n'd' to position the can properly as Well as to hold the can securely in place while a coiling operation is effected.
Another object of this invention is the provision of an improved platform for sliver coilers wherein improved roller holding means are arranged to engage the can rollers and wherein improved guide means are utilized to engage the can rollers so as to guide the can into its proper position on the-coiler platform. 7
The invention in one form comprises a coiler having a can with a plurality of rollers thereon and a platform having a plurality of roller holding means together with a plurality of roller guide means arranged to engage the can rollers and to guide them in to cooperative engagement with the roller holding means on the platform.
The invention will be better understood from the following detailed description taken in conjunction with the accompanying drawings in which Fig. l is a side view of a coiler having a wheel mounted can; in which Fig. 2 is a plan view of a coiler platform constructed according to this invention; in which Fig. 3 is an enlarged view taken along the line 33 of Fig. 2; and in which Fig. 4 is a plan view of a modification of the platform shown in Fig. 2.
With reference to Fig. l the numeral 1 designates a coiler base on which a pedestal 2 is securely affixed in conventional fashion. Mounted atop the pedestal 2 is a coiler head generally designated by the numeral 3. A can 4 is positioned on rotatable platform 5. As is well understood in the art suitable mechanism is disposed within the pedestal 2 for imparting rotary motion to platform 5 and in addition to impart suitable motion to a sliver fed into the top of the head 3 whereby the sliver is coiled in a predetermined pattern within the can 4.
As can be seen in Fig. l the can 4 is provided with a plurality of rollers 6; I V
According to this invention the rotatable platform 5 is contfucted was to hold the roller mounted can 4 in position on the platform" and so as to enable an operator readily to position the can 4 in its proper centered re1ation on the rotatable platform 5. To this end and as best shown in Fig. 2, the platform 5 is provided with a plurality of holding means generally designated by the numeral 7. These holding means 7 may constitute an abrupt abutment 8 together with an inclined surface 9,- the abutment 8 and inclined surface 9 being shown enlarged in Fig. 3. of the invention it may be possible or desirable to eliminate the inclined surface 9 or the abutment 8 Also it is within the contemplation of thepresent invention that the surface 9 and abutment 8 could take the form of a simple recess for receiving each can roller. As is indicated by the arrow in Fig. 2 the direction of the rotation of the platform 5 is clockwise. Thus the abutments 8 are disposed on the side of the holding means 7 which is opposite from the direction of rotation of the rotatable platform 5. In this manner thexrollers of the can engage the abutment 8 and are securely held thereagainst as the can rotates against the frictional drag effect of the sliver being coiled. Inclined surfaces 9 are disposed on the part of holding means 7 which is in the direction of rotation of the platform. Of course'the purpose of the inclined surfaces 9 is to allow the can to be gradually lowered from the main portions 10 of the platform face into the holding means and into engagement with abutments 8 and to impede rotation of can 4 in a clockwise direction relative to platform 5.
For the purpose ofguiding the rollers into proper engagement with the abutments 8 forming a part of the holding means 7, i.e. in order to properly center the can 4 on the rotatable platform 5, guide means in theform of the outer guide elements 11 are provided. In addition, the inner guides 12 are also provided in spaced relation to the outer guide elements 11. Thus with the can positioned in approximately its correct position on the platform 5 rotary motion is imparted to can 4 manually'in a counter clockwise direction and causes each of the rollers to ride between one of the outer guides 11 and its associated inner guide 12 and thereby causes each roller toassurne its position within one of the holding means 7.
In Fig. 2 the platform 5 is made up of an outer annular part 5A and an inner circular part 513 secured to the outer part by bolts 5C. Also in Fig. 2 the inner guides 12 eX- tend only to the inner edge of annular part 5A.
As is shown in Fig. 4 the platform 5 may be constructed of one piece secured in place by bolts 5D and the inner guides 12A may extend into the center SF of the platform 5 where they unite. By theconstruction of Fig. 4 the rollers are positively guided irrespective of the particular relation between can 4 and platform 5 so long as one or more rollers is in engagement with the platform. The arrangement of Fig. 4 is the presently preferred arrangement.
Preferably the rollers used in our invention are of the swivel type because such rollers are not subject to congestion by lint. As is best shown in Fig. 3 each of these rollers comprises a rotatable wheel 13 which is mounted on an axle 14 secured to a yoke member 15 comprising a pair of spaced legs 15A and 15B and a bight portion 15C through which a swivel pin 16 extends. Pin 16 is anchored in a plate 17 affixed b'y'bolts' 18 and nuts 19' to a spider 20. Spider 20 preferably is in the form of a triangle of unitary construction and is secured to the can by set screws 21 which engage the flange of can 4 to hold the swivelled rollers in place.
Can 4 is provided with a bottom 22 whose edge 22A is gripped between the flange ring 23 and the can wall 24. A reinforcing skirt 25 is mounted about the lower edge of can wall 24 and the flange assembly is held together by a plurality of units 26. The" manner of It will be understood that for some applications mounting the swivel rollers 6 to the can is claimed in copending application Serial Number 747,232, filed July 8, 1958 and assigned to the assignee of this invention.
