I-Ieretofore in the manufacture of rubber dipped articles, such as latex rubber surgeons glovesjconsiderable hand operations were essential to their manufacture thereby making the unit cost high. Although certain improvements were made in some areas of the handling of the glove forms, the improvements in manufacturing were directed principally to the manual manipulation of a single group of mandrels through several operations. Such action required complex motions with intricate mechanisms and related parts, without materially improving output and cost. Those improvements directed to multiple forms on a single pallet required extensive manual manipulative steps which increased the cost per unit produced.
The purpose of this invention is to provide a new and improved method and apparatus which materially increases the production and quality of latex dipped products while reducing the production costs. Further, the accuracy of reproducibility has been enhanced by this invention. The pallets are automatically manipulated over the full closed path of the manufacturing operation such that the finished glove is lubricated on the inside as well as the outside without requiring an inversion of the glove or requiring a separate operation of dusting the gloves.
BRIEF DESCRIPTION OF THE INVENTION The present invention is directed to a manufacturing process and apparatus which provides for a plurality of stations (preparation or treatment) cooperative with a latex dip station for making latex gloves. The stations are interconnected automatically such that a plurality of pallets with straps 'and glove forms thereon are manipulated at the stations and are continually moved automatically and sequentially from one station to the other. Each pallet supports a plurality of removable straps and glove forms to facilitate the changing of sIzes.

DETAILED DESCRIPTION Referring to the drawings, and more particularly to FIG. 22, there is shown a portable articulated pallet 10 which is used to handle, store and manipulate a plurality of glove forms along an apparatus to be described. Each pallet consists of a plurality of elongated tubular channel members 11 arranged in parallel rows with each member having a longitudinal center line. Each tubular channel member 11, see FIG. 19, has a pair of laterally extending projections 12 that extend along the respective upper side edges thereof for the full length of the pallet. A bracket 13 is suitably secured to the respective side ends thereof to facilitate the joining of the elongated tubular members 11 into a single unitary pallet. Each bracket 13 has a pair of bores at the respective ends thereof such that adjacent brackets have portions overlapping with their bores aligned for receiving pivot means 14 consisting of an axle l5 and a ment of a strap 20 to be described and a spring clip 18 (FIG. 21) suitably secured to the lower side surface portion at the center of each channel member 11 for a purpose to be described.
A generally U-shaped strap member 20 with a' projection 22 on the outer edge portions of the respective leg members is adapted to receive the projections 12 of the tubular channel member 11, such that the strap members 20 are adapted to abuttingly engage the plate 17 and the clip 18. As shown in FIGS. 21 and 22, there are five channel members 11, with each channel member 11 receiving two straps 20 thereby providing straps per pallet. Each strap member has secured tion 34 FIG. lb) has a receiving end 38 for a purpose to be described. An endless conveyor means 39 traverses a portion of the length of the forwardly disposed pair of tracks 34 and travels the full length of and parallel to the rails of rearwardly' disposed tracks 35. I
A transfer means, designated as 40, operates to con-' vey pallets 10 from the endless conveyor 39 to an endless-conveyor 41, which conveyor 41 has one end located on the forwardly disposed portion of tracks 34 of the upper guide section'3l 'and extends for the full section 32. Transfer means 40 has suitable vertically thereto, as by a conventional bolt and nut arrangement,
a plurality of glove forms or mandrels 23. In the example shown there are 12 mandrels or glove forms on each strap. To insure that the straps 20. are firmly secured to the pallet each tubular member 11 has a pair of earns 24 mounted for pivotal movement on the respective end portions. Spring means 25 biases such cams 24 into engagement with the lower surface of the strap members and maintains such strap members 20 firmly secured to the pallet for movement therewith.
The upper surface of the cams 24 are eccentrically contoured, as at 26, to insure a positive locking engagement with the respective straps 20.
The glove making apparatus comprises a suitable 1 base or support means having vertically extending studs and cross braces, designated generally as in FIG. 1a.
Support means 30 has suitably mounted thereon guide means consisting of an upper guide section 3l and a lower guide section 32. Upper guide section 31 has a forwardly disposed pair of tracks that are generally C- upper respective side surfaces of the support means 30, such that the respective open portions face each other providing tracks for the movement of the respective side wheels 16 of the pallets, which arrangement is.
shown generally in FIGS. 8, l3 and 22. Located on the respective side edges in alignment with respective forwardly disposed tracks 34 are rearwardly disposed tracks 35 FIGS. 1a and lb) that are similarly C-shaped 33 of, the guidemeans connects the respective for-- wardly disposed pairs of tracks '34 with the forwardly disposed tracks36 of the lower section 32, wherein such bridging section 33 has curvilinear portions to facilitate movement of a pallet from the upper guide section 31 to the lower guide section 32. The rearwardly disposed pair of rails 35 of the upper guide secshaped, designated 34 (FIG. 8), which extend along the v extending brackets 42 (FIG. 7) which support the forwardly disposed tracks 34 and a pair of spaced upper guideways 43. Suitable cross braces, as shown in FIG. 8, support a pneumatic cylinder 44 which has its piston rod 45 suitably connected to a bracket 46, which bracket 46 is connected to a carriage 47. Carriage 47 has a plurality of rollers 48 which are received by the guideways 43 to facilitate the reciprocation of carriage 47 thereon. Carriage 47 has a plurality of downwardly extending brackets 49 which have pneumatic cylinders 50 secured thereto. The respective rod ends of cylinders 50 have dogs 51 secured thereto which dogs have U-shaped recesses therein for frictionally engaging the axles 15 of the respective pallets for moving such pallets from the conveyor 39 to the conveyor 41 in a manner to be described. 4
Conveyor 41 has a plurality of sprockets 52 mounted on both sides of the supporting structure 30. However, only the one side is shown in FIGS. la, 1b, 2, 7 and 11. The respective sprockets 52 guide spaced drive chains, designated generally as 54 which ride on U-shaped guideways55 (FIG. 11) that are substantially in sideby-side alignment and parallel to the guide rails of the bridging section 33. Certain links for the drive chains 54 have brackets 56 to which longitudinally spaced cross braces 57 are joined to thus assure alignment of placement of the pallet 10 after it passes over such dog 60. The lowermost sprocket of the conveyor 41,
designated as 53 in FIG. 2, is of a diameter such that the pallets 10 passing thereover are deflected at their pivots to an arcuate configuration. This disposes the respective outer end portions of "the rows of glove forms away from each other't'o permit the strippingof the gloves therefrom, as shown in FIG.*2.
An indexing means, located on the lowerf'forward' portion of the support means (FIGS. la and 2), in-
cludes a pair of spaced motors 61 and 62; Motor 62 is connected by a pair of crank'arms 63 and 64 to the 'intermediate portion of a lever 65. "Lever 65 has one end pivotally connected to a vertical support 67, of support means 30, and its other end connected to a truck 68, which truck 68 has spaced rollers 69 at the respective end portions thereof. In a similar manner a plurality of other levers (FIGS. la, b, and 3) are each pivotally connected to individual trucks 68. The trucks 68 are interconnected by rods 70 which assures simultaneous movement of the trucks 68 for a purpose to be described. Journaled for movement on the respective rollers 69 of each truck 68 is a U-shaped rail 71 FIG. 10), which rail 71 has downwardly depending brackets 72 with each bracket having a recess 73 on its lower end. The recesses 73 are adapted to engage the axles 15 of pallets 10 to assure simultaneous movement of the respective pallets in a manner that will be described. a
As viewed in FIGS. la'and 2, the rearward end portion of rail 71 is pivotally secured to one end of a lever 75. The other end of lever 75 is pivotally secured to one end of crank arm 77. The other end of crank arm 77 is pivotally secured to a bearing block 78 which is mounted on a support channel 79. Crank arm 77 has its intermediate portion pivotally connected to one end of a pitman arm 80 which in turn is driven by the motor 61 through crank arm 81. Rotation of crank arm 81 operates to reciprocate the rail means 71 along a linear path, as viewed in FIGS. 2 and 3, which is first in a leftward direction and thence in a rightward direction.
Suitably mounted on the support means 30 are a plurality of L-shaped locking means 85. Each locking means 85 (FIGS. 12 and 13) has one arm member 86 extending upwardly and outwardly with a roller 87 journaled thereon in alignment with the rail 71 for rolling engagement therewith to thereby pivot the L- shaped member locking means 85 about pivot means 88, as seen in FIG. 12. The other armmember 89 of the locking means 85 has a recessed portion 90 which is adapted to engage the axle 15 of a pallet 10 to secure such pallet against linear movement. When the rail 71 is in a lowered position as shown in FIG. 12, it depresses roller 87, which in turn pivots thelocking means 85 about pivot means 88 in a clockwise direction, as viewed in FIG. 12, thereby unlocking the pallet to permit the movement of the pallets in a manner to be described. A coil spring 91 is secured to the locking means 85 to bias such locking means in a counterclockwise direction as viewed in FIG. 12 which assures the locking of the pallet by the locking means 85 upon movement of rail 71 in an upward direction away from the locking means 85.
A transfer conveyor or elevator is located on the rearwardmost portion of the glove makingmachine (as shown in FIGS. 1b, 5 and 6). Extending vertically are a Mounted on the upper cross brace 104 is a variable speed motor whose output is connected by a shaft 116 with a pair of spaced right angle drives 117 to a pair of rods 118 which, in turn, are connected to right angle drives 119. The output of each right angle drive 119 is connected via an axle 120 to a track section 121. Hence, actuation of motor 115 rotates rods 118 and axle 120 which in turn rotate tracks 121. Each track 121 is C-shaped and in alignment with rearwardly disposed tracks 37.
The tracks 121 are located on both sides of the apparatus as shown in FIG. 6; however, only one side will be described. Each track 121 has an upwardly disposed longitudinally extending bracket 122 (FIGS. 14 through 18). The lower left end portion of the FIG. 6 depicts broadly the locking means which is shown more clearly in FIGS. 16, 17 and 18. Bracket 122 has a pair of bosses 125 which pivotally support an elongated bracket 126 as by a pair of levers 127 and 128. Bracket 126 has a plurality of downwardly extending projections 130 which are adapted to abuttingly engage the axles 15 of a pallet. Brackets 122 and 126, respectively, have laterally extending projections 131 and 132 in longitudinal alignment, as best seen in FIG. 16. One end of a rod 133 is secured to lateral projection 132, while the other end of rod 133 is slidingly received by the lateral projection 131. A compression spring 135 encompasses rod 133 and operates between projections 131 and 132, such as to bias bracket 126 rightwardly as shown in FIG. 17 into locking position as shown in FIG. 18 whereby the projections 130 engage the respective axles 15. Pivotally secured as at 136 to an upwardly extending boss 137 (FIG. 16) of bracket 122 is a cam locking member 138. Cam locking member 138 has a semi-arcuately shaped recess 140 at its outermost end portion and an arcuately shaped recess 141 at its intermediate portion whereby recess 140 is adapted to frictionally engage and encompass a portion of axle 15 to secure and prevent the pallet from movement relative to bracket 122 while arcuatelyshaped recess 141 facilitates the locking and unlocking in a manner to be described. A pin 142 is journaled on the outermost end portion 'of bracket 126 and rides in the arcuately shaped recess 141 to cam the'locking member 138 upwardly out of engagement with the axle 15 as shown in FIG. 17 or into engagement with the axle 15 as shown in FIG. 18. As shown in FIGS. 17 and 18, mounted on tracks 37, closely adjacent to the pair' of vertically spaced columns 101 with suitable guide rails 102 thereon. Elevator 100 has a pair of vertically extending channel members 103 connected by suitable cross braces 104. Bosses 105 secured to the respective side portions of channel member 103 have a central threaded bore therein and rollers 106 which frictionally engage the rails 102 to maintain the alignment. Each column 101 has a suitable boss 107 mounted on the lower portion thereon for supporting for rotation a threaded rod 108 which is threadedly received by a threaded bore of bossl05. The rotation of threaded rods 108 controls the vertical reciprocal movement of the channel members 103 and cross braces 104 on the guide rails 102. The upper end portion of each threaded rod 108 is connected to a right angle drive means 109 which in turn is connected via rod 110 to the output of variable speed motor 111.
transfer conveyor, is an unlocking means comprising the bracket 151 which is secured to the guide rail having mounted thereon a cylinder 152 which has a piston 153 movably mounted therein with its rod 154 extending outwardly therefrom and in alignment with the pivotal bracket 126. Rod 154 is adjustably mounted on the piston rod to facilitate locking and unlocking of the cam member 138 with respect to the axle 15. Pressurization of the head end of cylinder 150 extends the rod 154 to engage bracket 126 which then moves bracket l26 leftward, as seen in FIG. 18, against the action of spring 135, whereby pin 142 moves, as by a pivoting action, the locking member 138 upwardly Y away from the axle 15 of the pallet. Conversely, upon pressurization of the rod end of cylinder 152, the reverse occurs'with spring 135 returning the bracket 126 rightwardly so that pin 142 cams the lock-ing member downwardly into locking engagement with the axle 15.
Located beneath the forward portion of guide rails 71 are a plurality of tanks A, B, C, D, E, and F. Tank A contains a suitable inlet pipe and drain to provide forsupply of a liquid to the tank for a pre-wetting of the glove forms. Tank B is an ultra-sonic cleaning tank for suitably cleaning of the glove forms. Tank C is a rinse tank which may contain either cold or hotwater. Tank- D contains the hot rinse water while tank E contains the cold rinse water. Tank F contains a glove lubricant in liquid form, which on contacting the glove forms deposits a thin layer of lubricant thereon.
As shown in FIG. 3, tracks 36 are sectioned as at 36a and 36b to provide a sectioned track 36A. Track section 36A along with the pallets and glove forms thereon is adapted to be raised and lowered whereby the glove forms are dipped into the respective tanks A through E. A motor 160 FIG. 4) mounted on suitable cross beams above tank C has its output connected via shafts 161 and 162 to right angle drive units 163 and 164 which in 'turn are connected respectively to rods 165, which in turn .are connected to right angle drive units 166 for driving four downwardly extending threaded shafts 167. The respective tracks 36A (one on each side of the apparatus and only one side shown in FIG. 3) are portion 36F adjacent to sectioned track 36A. Track section 36F is similar to track section 121 of that shown in FIGS. 5 and ,6 in thattrack section 36F has connected thereto a motor similar to motor 111 which will raise and lower the track section 36F and in addition thereto has its track section 36F connected to a pair of right angle drives as 119 in FIG. 6 so that track section 36F can be rotated in arcs of revolutions for drying the glove forms mounted on pallets that are secured to such track sections. The pallets secured to track section 36F can thus be lowered, to dip the glove forms into the lubrication tank F located immediately'below and thence beraised to remove the glove forms from tank F. Thereafter the pallets .and track section 36F is that the glove forms have the fingers pointing upwardly to dry the lubricant thereon and to assure an even distribution of the lubricant without permitting the collection of an excess amount of lubricant on the finger tips. With the glove forms resting in the fingers up position,
the glove forms are conditioned for movementinto the v drying operation. The raising and lowering of the glove forms and pallet is similar to that shown in U.S. Pat.
' rotated through a complete revolution and a half, such No. 3,320,638, the structure of which is incorporated for a period of time depending on the thickness of the layer desired. The coagulating action of the calcium chloride on the latex solution causes a smooth thin layer of coagulated rubber to be deposited on the surface of the form. The latex dipped glove forms are then dipped into tank I which contains carbon dioxide gas, which accelerates the coagulation of the latex on the glove form.
The section of the track 36 above tanks G, H and I are sectioned and indicated as 36G, 36H and 361 respectively. Each of these movable sections 36G, 36H and 36l are similar to the track section 36F and similar to elevator wherein each track section is suitably supported by brackets such as brackets 122 which are movable upwardly and downwardly as by motor 111 as well as rotated as by motor 115 so that pallets located thereon dip the glove forms thereon into tanks G, H and I respectively and are then raised to clear the tanks and thence are revolved so that the pallets are moved through selected revolutions to assure an even distribution of the solutions as well as to facilitate the drying of such solutions on the glove forms and thereafter align track sections 36G, 36H and 36I with the tracks 36.
The structure for raising and lowering such sectioned tracks is similar to that shown by U.S. Pat. No.. 3,320,638 which structure is incorporated herein by reference. Suitable lock means identical to that shown in FIGS. 16, 17 and 18 are provided for track sections 36G, 361-1 and 361 to insure that the pallets 10 associated with each section of track and its pallets are manipulated as a unit. The individual track sections 36G, 36H, and 36I are individually manipulated so that each may be revolved in their own individual cycle.
The pallets on leaving the track section 36E are moved'into a washer unit via tracks 37 in cooperation with an endless conveyor 186. Washer unit 185 has suitable spraying heads therein supplied by water from -a suitable pressure source for directing a spray onto the glove forms for a leaching operation. After the washing is completed the glove forms are moved closely ad jacent the end of track section 37 (FIG. 5). This is accomplished by conveyor 186 leaving the pallet designated 10' in FIG. 5 such that a carriage 190 is adapted to transfer such pallet 10 into the position shown by palletlO". Carriage 190 is secured to a pair of spaced racks 191 which racks are in meshing engagement with spur gears 192 adapted to be driven by suitable means not shown. Only one side of the carriage will be described. Carriage 190 has a pneumatic cylinder 193 which is adapted to raise and lower a U- shaped cam member 194. Cam member .194 is adapted to engage one of the axles 15 of the pallet located thereabove upon pressurization of the head end of cylinder 193. Once cam member 194 engages axle 15, such carriage 190 can transfer a pallet to and from the elevator as by rotation of the gear 192. After the transferring of a pallet is accomplished, it is secured to the elevator 100 by the locking means described above and as shown in FIGS. 16, 17-and 18.
Located immediately below elevator 100 is a dip tank I which contains a lubricant fluid which deposits a thin Iayerof lubricant on the glove forms in a manner to bedescribed. It is to be noted that carriage 190 contains separate racks 191 on each side thereof to facilitate a smooth transfer of the pallet.
