Edwards, Charlotte, N.C., and Richard G. Levine, Lawrence, N.Y., assignors to Emile Mills Inc., New York, N.Y., a corporation f North Carolina Filed Feb. 3, 1965, Ser. No. 430,132 U.S. Cl. 112-2 Int. Cl. D04b l/26 13 Claims ABSTRACT 0F THE DISCLOSURE The present invention relates to a method and means for processing tubular fabric articles in which ends of the articles are closed in an integrated operation that is capable of high-speed production with a compact and simple arrangement that requires only a minimum of handling, which minimizes labor requirements and the danger of damage of the articles during handling.
Briefly described, the method of the present invention involves placing of tubular fabric articles on forms at a receiving station, closing an end of each article while it remains on its form as the form advances through an end closing station, and removing the articles from the forms at a removal station. In addition, the articles may be inspected while they are on the forms at the receiving station without further handling and the articles may be everted as they are removed from the forms after end closing without requiring any further handling between the end closing and everting steps. Thus, an integrated operation is carried out without handling of the articles between steps, and with the different steps being carried out at different stations so that there is no delay at any station while a preceding step is being performed, thereby rendering the invention capable of high-speed production. Preferably, the movement of the forms is continuous with the operations being carried out on the articles as the forms move continuously so as not to slow down the production rate.
This advantageous processing is obtainable by the means of the present invention, which basically comprises conveyor means that convey article carrying forms through the receiving, end closing and removal stations, with the forms arranged for receiving open-ended articles at the receiving station such that open ends of the articles are disposed at the otuer ends of the forms for closing of the article ends -by closure means in ythe end closing station while the articles remain on the forms as the forms advance through the end closing station to the removal station at which removal means remove the closed end articles from the forms.
In the preferred embodiment, .the means of the present invention is utilized in the manufacture of hosiery to close the toe ends of the tubular fabric articles in an operation integrated with both inspecting and everting of the hosiery article wtihout intermediate handling and with the inspection, toe closing, and everting being performed at different stations for simultaneous, expeditious production, which is further expedited by continuous movement of the forms on which the articles are carried as the operations are being performed. The forms used in the preferred embodiment are hosiery inspecting and turning forms 3,420,196 Patented Jan. 7, 1969 that are disposed to extend laterally from a conveyor means for ready access for mounting the hosiery articles thereon and to present the article ends conveniently for horizontal feeding to the closure means, which is preferably a sewing machine disposed adjacent the outer ends of .the forms for feeding of the toe ends of the articles therethrough as the forms advance continuously through the end closing station. The hosiery articles are initially mounted on the inspecting and turning forms at the receiving station where they are also inspected for defects, with the use of a mirror for inspecting the opposite sides, if desired. The articles remain on the forms and are not handled again, except for guiding the toes to the sewing machine, until after the toes are closed and the articles are everted and removed from the forms at the removal station. The simultaneous removal and everting is accomplished by pneumatic means that draws the closed toe articles through the hollow interiors of the turning forms, toe end first, and discharges the articles from ythe opposite ends of the forms as the forms move continuously through the removal station. The pneumatic means may be alternatively operable to eject articles by blowing without turning so that when a defective article is noticed upon inspection that article can be removed at the removal station without everting, the article remaining in unturned condition to facilitate correction of the defect.
The various features and advantages of the present invention are contained in the preferred embodiment described in detail below and illustrated in the accompanying drawings, in which:
FIG. 1 is a plan view, partially broken away, of a hosiery inspecting, toe closing, and everting machine according to the preferred embodiment of the present invention;

The forms 14 and hosiery H are `then conveyed through a toe closing station B at which the open toe ends 16 of the hosiery are closed by the operation of a sewing machine 18, `after which the forms 14 advance through a removal station C in which pneumatic means 20 operate to simultaneously evert and remove the closed-toe articles through the forms 14 onto a collection table 22. The empty forms 14 then continue on to the receiving station A ready for receipt of another hosiery article.
The conveyor means 12 is supported on an upstanding frame 24 on which is mounted a pair of laterally spaced bearings 26 that support a horizontal drive shaft 28 in cantilever fashion. The drive shaft 28 has fixed thereon a pair of spaced, vertically disposed, parallel sprockets 30 for driving a pair of parallel endless conveyor chains 32. The drive shaft 28 also carries a drive sprocket 34 that is driven by a drive chain 36 from a reduction unit 38 that is mounted on the frame 24 `and is driven by a belt and pulley connection 48 from a drive motor 42 also mounted on the frame 24.
The conveyor chains 32 are trained over the drive shaft sprockets 38, under a pair of smaller secondary idler sprockets 44 that are beneath the drive shaft sprockets 38, and around a pair of large primary idler sprockets 46 spaced from the drive shaft sprockets 34 to dispose the conveyor chains 32 with a horizontal upper `reach 48 between the primary idler sprockets 46 and the drive shaft sprockets 38. The secondary idler sprockets 44 are mounted on a horizontal shaft 58 that is supported in cantilever fashion by a pair of bearings 52 xed to the frame 24. Similarly, the primary idler sprockets 46 are mounted on a horizontal cantilever shaft 54 mounted in a pair of bearings 56, which bearings are adjustably bolted to the frame 24 and are `adjusted by positioning bolts 58 to control the slack in the conveyor chains 32.
The conveyor chains 32 carry a plurality of horizontally disposed tubular carriages 68 that are spaced along the length of the chains 32, with each carriage 68 extending laterally between the conveyor chains 32 and secured thereto by brackets 62. In the embodiment illustrated, there are thirteen such carriages 68 equally spaced on the conveyor chains 32 on the outer surfaces thereof so as not to interfere with the sprockets and to dispose the carriages above the chains along the upper reach 48 thereof.
Each tubular carriage 68 has a hollow interior 64 extending between an inner end 66 adjacent the frame 24 and an opposite outer end 68 having an enlarged outer face 78 for abutment of the inner end 72 of the form 14 thereagainst and having three vertically spaced, outwardly extending attaching flanges 74, 76 and 78, with the upper ilange 74 and lower ange 78 disposed for seating of the form 14 therebetween in horizontal laterally extending disposition, and the center fiange 76 disposed for seating in a mating recess 88 in the form 14. The form is fixed to the flanges for support by the carriage 60 by bolts 82 passing through the flanges 74, 76 and 78 and intermediate portions ofthe form 14.
The forms 14 in the embodiment illustrated are similar to conventional hosiery inspection and turning forms, having a hollow interior 84 aligned with the interior 64 of the attached carriage 68 and having yrelatively wide, flat faces 86 that taper to a nar-row outer end 88 and contoured sides 98 connecting the at faces. This shape facilitates mounting of hosiery H on the forms as hosiery is conventionally formed with a diameter diminishing toward the toe end 16. The substantial at surface of the faces 86 also facilitates inspection of the hosiery H at the receiving station A. Inspection is further facilitated by the use of a mirror 92 adjustably mounted on a bracket 94 extending from the frame 24 to position the mirror below the upper reach 48 of the conveyor chains 32 at the receiving station A so that an operator may view the side of the hosiery H facing the mirror 92 from outside the path of the forms 14. The mirror 92 may be mounted suitably for pivoted adjustment to provide desired viewing by the particular operator.
The receiving station A is located conveniently at one end of the upper reach 48 of the conveyor chains 32 where the operator can stand in line with the advancing forms 14 and easily slide the hosiery H onto the horizontally extending forms and inspect the hosiery at the same time. The forms then progress along the bottom reach 96 of the conveyor chains 32 and up around the primary idler sprockets 46 to the toe closing station B, which is ralso conveniently located adjacent an end of the upper `reach 48 of the conveyor chains 32.
Located in the toe closing station is the sewing machine 18 mounted on `a table 188 and having a work plate 182 extending horizontally closely adjacent the path of the outer ends 88 of the forms 14 and in generally the same horizontal plane. The feed of the sewing machine 18 is generally parallel Wtll the d irction of movement of the forms 14 so that the toe ends 16 of the hosiery H may be fed to the sewing machine 18 to close the toes as the forms 14 progress through the toe closing station B. However, a slight inclination of the sewing machine feed in a horizontal plane may be desirable to impart a desired taper to the closed toe.
The forms 14 and closed toe hosiery H advance from the toe closing station B along the upper reach 48 of the conveyor chains 32 to the `removal station C at which the closed toe hosiery H is simultaneously -removed and cverted by suction through the hollow interiors 84 of the forms 14, toc ends 16 rst. The suction for removing and everting is provided by the pneumatic means 28 that engages the inner ends 66 of the form carrying carriages 68 sequentially as the carriages advance continuously through the removal station C.
Connection of the carriages 68 to the pneumatic means during continuous advance of the carriages is accomplished by shiftable annular collars 184 carried on the inner ends 66 of the carriages to extend the effective length of the carriages into seating disposition in the outer end 186 of the connecting conduit 188 of the pneumatic means 28. The annular collars 184 are normally retained in retracted conduit clearing position (FIGS. 1, 2 and 7) by coil springs 189 on each side of the carriages and having their ends secured to the carriages 60 and collars 104 with the retraction limited by stop screws 118 projecting from the carriages 68 for abutment by cylindrical anges 112 extending along the carriages from the collars 184. The collars 184 and attached flanges 112 are retained against rotation on the carriages 68 and are limited in projection by 'additional stop screws 114 secured to the carriages 68 and accommodated in longitudinal slots 116 in the flanges 112.
Projecion of the collars 184 into seating disposition in t-he connecting conduit end 186 is accomplished by a cam 118 mounted on a bar 128 depending from the frame 24 through the removal station C above the collar flange 112 location. The cam 118 faces the connecting conduit 188 and is engaged by cam following rollers 122 mounted for free rotation about vertical axes in blocks 124 projecting upward from the flanges 112. Each roller 122 normally rides on the side of the bar 128 as its carriage 60 `approaches the cam 118 and then it rides on the cam to project the collar 184 into connecting engagement with the conduit 188, with the cam 118 contoured to project the tapered outer surface 126 of the collar 104 from the retracted position shown in dot-dash lines in FIG. 4 into seating engagement in the mating inwardly tapered surface 128 of the conduit outer end 186, also shown in dotdash lines in FIG. 4, in the direction of the arrow in FIG. 4. The cam 118 is further contoured to retain this seating engagement as the carriage 68 progresses a short distance and then to release the collar 184 to permit it to retract out of conduit engagement.
The connecting conduit 188 is adapted for sliding movement upon engagement by the carriage collars 184 by being mounted in an upstanding slide plate 138 that is positioned between -a pair of vertically spaced guide strips 132 extending parallel to the path of movement of the carriages 68, with the guide strips 132 engaging grooves 134 along the top `and bottom edges of the slide plate 138 to ret-ain and guide the plate for sliding parallel to the path of movement of the carriages 68. The guide strips 132 are xed to the frame 24, which also supports a vertical stop block 136, preferably of resilient material, in line with the slide plate 138 and against which the plate is normally retained by a pair of coil springs 138 extending between the Slide plate 138 and the frame 24 adjacent the stop block 136.
With this arrangement, the cam 118 will cause the carriage collar 184 of the approaching carriage 68 to engage the connecting conduit 188 and cause it to travel with the carriage until the collar is retracted at the end of cam engagement, at which time the coll-ar disengages the conduit, permitting the springs 138 to pull the plate 130 back to its initial stopped position against the stop block 136 in readiness for engagement of the conduit 108 by the collar 104 of the next approaching carriage 60.
The carri-ages 60 are maintained in alignment with the connecting conduit 108 for proper collar and conduit engagment by a pair of horizontally extending support beams 158 attached to the frame 24 and extending in supporting relation under the conveyor chains 32 through the removal station C, and by the aforementioned cam supporting bar 120, the underside of which is engaged by rollers 160 mounted for free rotation about horizontal axes in upstanding blocks 162 mounted on the carriages 60.
The connecting conduit 108 extends away from the slide plate 130 and is connected to` an end of -a flexible conduit 140, the other end of which is connected to a discharge conduit 142 having an intermediate elbow portion 144 and a discharge end 146.
Suction is created in the connecting conduit 108 for drawing of hosiery H through the forms 14 when the carriage 60 is connected to the conduit by projection of the collar 104 by an air compressor 148 that blows `air through a main line 150 into the elbow portion 144 of the discharge conduit 142 in the ydirection of the discharge end 146 thereof, which creates a suction in the connecting conduit 108 and in the interior of the form 14 during t-he period of collar connection with the connecting conduit.
The air compressor 148 is mounted on the collection table 22, which also supports a hosiery receiving tray 154 under the discharge end 146 of the discharge conduit 142 to receive hosiery H blown therefrom. To control the discharge of the hosiery, means 156 (shown diagrammatically in FIG. 1) of any well-known conventional construction may be utilized.
When a defective hosiery article is detected upon inspection at the receiving station A, it is usually desirable to segregate the defective article from the others upon removal and to remove the defective article without turning. This is accomplished in the present invention by a secondary air line 164 connected to the main line 150 by a valve 166 4and opening into the discharge conduit elbow portion 144 in the direction of the connecting conduit 108 so that when the valve is operated air will be blown through the secondary line 164, connecting conduit 108, carriage 60 and form 14 to blow defective hosiery onto a receiving tray 168 on the sewing machine table 100 in line with the location of the forms in the removal station C.
Operation of the valve 166 may be controlled by any suitable memory system to effect operation of the valve 166 when a previously detected defective article is positioned for removal. By way of ex-ample, the illustrated embodiment utilizes a depressible pin 170 held by friction in a bracket 172 at the outer end 68 of each carriage 60. When the pin 170 is `depressed by the operator to indicate that a defective article is on the particular form, the pin will contact a valve operating switch 172 mounted on a bracket 176 (FIGS. 2, 3 and 7) attached to the outer support beam 158 immediately in advance of conduit engagement by the collar 104 of the appropriate carriage 60 to operate the valve 166 through the electrical lead line 177 to momentarily blow air through the form for discharge of the defective hosiery onto the receiving tray 168 on the sewing machine table 100. The switch bracket 176 is upwardly contoured beyond the switch 174 to raise the depressed pins 170 to their initial position out of switch contacting disposition.
To operate the machine of the illustrated embodiment, two operators are required, one at the receiving station A and one at the toe closing station B. The machine is started by closing a drive motor switch 178 that turns on the drive motor 42 to cause continuous movement of the carriages 60 and associated forms 14, and by closing a compressor switch 180 that turns on the compressor 148 to rcreate la continuous suction in the connecting conduit 108. A rehostat 182 or other suitable variable control is set at a selected speed indication to provide a ydesired rate of travel of the forms 14. These switches 178 and 180 and the rehostat 182 -are mounted on a control panel 184 on the top of a protective housing 186 over the conveyor means elements of the machine.
The receiving station operator places hosiery articles H on the advancing forms 14 with the toe ends 16 of the yarticles at the outer ends 88 of the forms, and inspects the articles for defects, using the mirror 92 to inspect the portions of the articles on the opposite face of each form. Upon detecting a defect, the operator depresses the pin 170.
Simultaneous with the activity of the receiving station operator, the toe closing station operator places the toe ends 16 of the hosiery articles 14 in proper position on the sewing machine work plate 102 for feeding of the toe ends 16 through the sewing machine 18 to close the toes as the forms 14 move continuously past the sewing machine.
While the receiving station operator is continuously placing hosiery on the forms and inspecting the hosiery, and while the toe closure station operator is continuously feeding hosiery toe ends 16 to the sewing machine 18, the carriages 60 are sequentially engaging the connecting conduit 108 of the pneumatic means through the shiftable collars 104- (FIG. 4) to carry the conduit Iwith it for a short distance to remove the articles from the forms 14 and evert them through the forms and out of the discharge conduit 142 onto the tray 154, after which the connecting conduit 108 is released to return to its initial position for pick-up by the next carriage 24 as the empty forms 16 are conveyed to the receiving station A to receive another article. When a defective article has been indicated by depressing the pin V170, the pin will, when its carriage approaches the conduit engaging position, close the switch 174 to operate the valve 166 to canse the defective article to be blown from the form without everting.
Periodically the receiving trays y154 and 168 are replaced or, alternatively, conveyor means may be utilized, with or without the trays, to receive the articles and convey them to the next processing station.
The above-described machine 10 is illustrative of one application of the features of the present infvention, but the invention is not intended to be limited to the described details. For example, the principles could be applied to processing various types of tu-bular fabric articles other than hosiery; closure means, such as heat sealing devices and other means, could be used instead of a sewing machine to close the ends of the articles; other types of removing means may be used to remove the articles from the forms in place of the described pneumatic means and the connecting details may be varied, as, for example, by mounting the shiftable collar 104 on the connecting conduit 108 rather than on the carriages 60; and various other substitute arrangements for accomplishing the same purposes may be utilized without departing from the intended scope of the present invention, which is not intended to be limited except as defined in the appended claims.
