8 Claims.

This invention relates to the packaging or carding of articles of manufacture, such for example, as hair curlers. More particularly, the invention deals with a machine for automatically applying two or more curlers to a card to retain the s-ame against 'displacement therefrom and to deliver the card assemblages from the machine into a suitable receptacle. More particularly, my invention deals primarily with the automatic delivery of cards and workpieces, such as hair curlers, to what may be termed an assembly station, and in so actuating and manipulating the curlers so as to effect assemblage with cards held in fixed position at said station, and finally in release oi the cards for delivery through the machine. Still more particularly, the invention consists in employing what may be termed a dual machine whereby two stacks of cards may be employed and assemblage of workpieces performed on a card from one stack while preparation is being made for assembly on -a card of the companion stack.

The novel features of the invention will be best understood from the following description when taken together with the accompanying drawings, in which certain embodiments of` the invention are disclosed, and in which the separate parts are designated by suitable reference characters in veach of the views; and in which:

In Figs.` 1 to 3 inclusive, I have shown at 2|, part of the upper portion of a table, base or stand, upon which my improved machine is constructed. The machine comprises what may be termed two similar operating units, or a dual machine, the units operating alternately so as toprovide for a workpiece loading time while the carding operation is being performed by the companion machine unit. As each unit is of the same construction, one detailed description will be given of one unit andthe other unit referred to as and when necessary to clarify the present description.

Each unit of the machine comprises vertical supporting plates 22-22 and 23-23, the platesV of these units being joined by cross straps, as at 24 and 25 respectively. Secured to the lower ends of the plates 22-22 are grooved guideblocks 26-26 and 21-21 in which are mounted manually adjustable slidable pivots 28-28 and 29-29, the pivots being adjustable through thei medium of screws 30-30 and 3I-3I'. All of said screws have bearing mountings on end plates on the blocksl as clearly shown in Fig. 1 of the drawing. The supporting plates 22-22 have dove-tailed grooves 32 in the upper ends thereof, in which are mounted slides 33. At this point, and from now on, until further mention, references as applied tothe structure ofv one unit will be applied to the companion unit.

To the upper end of the slide is secured a horizontal plate 34 having a dove-tailed socket or recess 35 in the upper surface. thereof. Thus the parts 33-34 form what might be termed' an L-shaped table-like member constituting a vertically reciprocating part oi' the workpiece supporting platen mechanism. Mounted in the groove 34 is a platen supporting slide 36 to which a workpiece supporting platen,y 3.1 is secured. at a suitable position. The slide 36 has a downwardly extending arm 3&3` operating in an elongated slotted portion of the table 34. To the upper end of this arm is pivoted a lever 39 having at its lower end a slidable coupling through the-medium of an elongated slot 40, with a pivot pin 4l on the pivot 26-23- Substantially centrally of the lever 39 is a roller 42 which is adapted to operate upon a cani 4'3"-43 on a cam shaft 44 supported in the upright frame plates 22-22-2 Also secured to this cam shaft are cams 45--4'5' operating upon rollers' 4'6onthel slides 33. Secured to the shaft 44j betweenl the plates 22;-22 is a drive sprocket 41" around` which passes a, drive chain 48,. which also passesV around` a sprocket 45'V on another cam` shaft 50 supported in the frame plates 23--232 Also on the shaft is another sprocket l over which passes a drivey chain 52;, passing around a similar sprocket on the motor or drive shaft 53 shown diagrammatically in Fig. Llof the: drawlng,

The cams 43-45 of the dual units are fixed at one hundred and eighty degrees to each other, so,` that when the workpiece supporting platen 31 of one unitisin the loading position or station, asseen-in Fi'gj. 1f', the platen of the companionY unit willA beat the assemblage-station in the process or assembling the workpiecewith the card. At this time, it willl also be well to mention'v that theA operation of the card pick-up and delivery' mechanism from the hopper will-be similarly" operated in the respective units.

VPivoted tosideV portions of the slides 35 are dogs 541 adapted to actuate product control or operativeA devices 55, the dogs 54- being maintained in the position shown in Fig. 1 by gravity orv otherwise, and these dogs operate in conjunction with adjustable trips 56 at sides of the tablel 34". The trips 56 are adjusted into such positions as' to move and hold the dogs 54 in raisedA position, as shown in Figs. 15 and 16, in the operation' of the control devices 55, supporting the latter inthe work engaging position, as seen in Fig. l5: and 16, while assembling workpiecesY or articles 51 with cards 56. In the construction shown, the workpieces are in the form of hair curler devices, note Fig. 1'0, comprising an elongated body V59 with which is pivotally mounted a spring actuated jaw or finger 60v movable toward and from the body 59 and normally retained' on the body as is well known in the art. TheA curlers, as shown, have lateral' loop portions 61|, note Fig; 11', supporting rubber or other rollers 62 at one end of the body 55.. The jaw or finger 60 has an operating iingerpiece portion 63Vwhi'chis adapted to be engaged by the sliding plate. 64 of theV control.: device 55 inthe operation of raising the finger 60 for engagement with the card 5S, as later described.

The control device comprises a transversely' long bumper plate E5 adapted to be engaged by the dogs 54. The slide 54 is coupled to the bumper plate through a pair of screws 66 operating in elongated apertures 5l" in a bracket 68" adjustably supported at one end of the card supporting platen 69, as clearly seen in Figs. 'T and 8 of the drawing. The end wall of the platen 69 hasv a dove-tailed recess I6 in which the bracket 65 is mounted, as most clearly seen in Fig. 8 of the drawing. A spring il is ernpl'cyed tonormally support the bumper 55 and plate 64 in the position shown in Figs. 7 and 3.

It will beY Vapparent that after the dog 54 has passed over the trip 56, the dog will be thrown into the position shown in Fig. 17, return of the bumper 65 and plate 64 to the position shown in said latter gure. 1n returning the slide 36 from the position shown in Fig. 19, to the position shown in Fig. 1, the dogs 513 will oscillate over the tripsv 56 and again return to normal. position, as seen in Fig. l.

Supported upon the upper ends ofthe frame plates; Zit-213', on extension plates i2, are card storing hoppers 53, note Figs. 3, 7 and 13. The hoppers. comprise fourV vertical wall portions suitably supported for reception of cards of predetermined size and no speciiic detailed description. willY be made of the hoppers asV this. is of no particular importance.

Adjacent the forward wall of the hoppers 13 is a vertically adjustable card feed control plate 1.4', clearly seen in Fig. '7 of the. drawing. This controls the delivery of a single card 53 from the lower end of a stack of cards arranged in the hopper and supported upon a card delivery slide or feed member 15. This feed member has at its rear end portion, a shoulder 'I6 for picking-up Y cured to the shaft 5G is a crank disc or wheel Z having` a pin S3 with which is; coupled a sliding block 84 arranged upon the lever i9, thus providing a. crank. drive of the lever 79 in delivery of cards one at a time to the supporting platen 69.

Secured to the shaft 58 centrally thereof isa cam 8.5 adapted to aotuate a sliding air valve 86 through a roller 8i on the valve, engaging the cam with suitable spring means 88 normally maintaining the roller in constant engagement lwith the cam 85, note Figs. i and 5. The valve 86 operates in a: valve casing 89 with which is coupled a' suction pipe Se' leading to a suction pump 9| driven from the motor through a belt or other drive, as diagrammatically seen at 92 in Fig. 4. Gn the casing E9 are two control pipes 93 and S4. These pipes extend to the card supporting platen 65 of the respective units, as clearly illustrated in Figs. l and 3 of the drawing. The pipes are coupled through inner sides of the platens and open into and communicatel with distributing chambers 95 in the plat-ens which open thro-ugh the surface 'il through five orl mo-re ports,A as indicated at 5G. Note in this connection Fig. 6 of the drawing. The ports 96 are disposed'. in. spaced relation to* longitudinally accesos:

'arranged workpiece receiving recesses 91 inthe surface 11.

The lower surface 'II of the card supporting platen S9 is recessed t-o provide side guide finders 9B for reception of the card. The workpiece receiving recesses 91 are of sufficient ldepth to receive not only the fingers 60, but also eXe-d flange portions 90 of the die cut-out portion |00 of the card, as clearly seen in Fig. 9 of the drawing. In additionto forming the folda'ble lianges 99, the die cut-outs form, at the ends of the resulting cuts formed in the cards for reception of the curlers, retaining tongue members as at |0| and |02, the first of these tongue mem-bers being engaged by the finger or jaw `|50 and the latter by the finger-piece B3, when the curlers are assembled with the card, as clearly seen in Figs. 17 and 18. The platen 69 is supported on an L-shaped bracket |03 adjustably supported on the wall of the hopper in setting the platen 69 in proper alinement .with the lower end of the hopper or the delivery slide T5. It will be understood that the valve 86 is actuated to expose the pipes 93-94 leading to the pairs of platens 69 to timely create a suction in the passages 96 to suck and hold the card on the platens and to then periodically release or exhaust the suction to allow the card-s with the curlers mounted thereon to drop into a suitable receiver, not shown, after the work supporting platen has been returned to the position shown in Fig. 1. The valve 80 has exhaust ports 80 for exhausting the air from each of the pipes S33-9x4 in operation of the valve, as will be apparent. It will be noted that the port or passage |04 in the valve 86 is such as to expose the suction pipe 00 intermittently to each of the pipes .9B-914 as the valve is actuated through the cam 05.

Considering Figs. 13 and 16 to 19 inclusive, it will appear that the work supporting platen 31 has on the upper surface thereof, a pair of workpiece supporting recesses |05, each of which in the present construction is shaped to receive the body 59 ofthe curler, including the roller 62, and is further shaped to receive a finger portion |06 on the curler body by the offset in the recess |05, as seen at |01, most clearly shown in Fig. 19 of the drawing.

The pairs of curlers may be manually or otherwise placed in the work receiving sockets or recesses when the platen is in the position shown in Fig. l of the drawing. This operation being performed while the other workpiece supporting platen of the companion unit is in the loading or carding station beneath the card holding platen for attachment of the workpieces with the card, as shown in Figs. 14 to 19 inclusive.

`Then when the units are reversed, the other w-orlspiece supporting platen is positioned as in Fig. 1, and the workpieces assembled therewith.

`It will appear from a considera-tion of Fig. 1 of the drawing, that springs 39' are employed for holding the levers 39 or the'rollers 42 thereof in constant engagement .with the cams 43. It will appear from a consideration of Figs. 3 and '7 of the drawing, that the card carrying or delivery slide l5 operate in grooves 018 in side walls of the hoppers, and further that the levers I9 have their pivots 18 in U-shaped members |09 secured to the card carrying and delivery slides, as clearly seen in Fig. 7 of the drawing.

My improved machine is of simple economical construction and by 4employing the dual units actuated in the manner described, the machine becomes `highly efficient in producing the intend- 6 ed cardingv operation.` While 'I have shown the machine as applied to carding devices of a specic type and kind, it will be understood that the machine is applicable to performance of carding operations of any kind, particularly where it is desirable to pass the device through a perforation or cut-out in the card, and still more particularly, where it is desired to perform two distinct feed motions of the device with respect to the card in providing a double lock or coupling engagement with the card as in the present construction.

Considering the operation of one unit of the machine, it will be apparent that a pair of curlers or other devices are placed in the apertures or recesses |05 when the work-piece supporting platen is in the position shown in Fig. 1. The next opera-tion consists in moving the wvork holder platen in the direction of the card supporting platen, it being understood in this connection that a card58 has been delivered to and is supported on the platen with the cut-outs as at 00 in a itat condition.

In Fig. 14 of the drawing the work supporting platen is shown in a position substantially the same as that shown in Fig. 1 and in Fig. 15, the work supporting platen is shown moved into i-ts rst stage beneath the card holding platen and the plate 04, the fingerpiece 63 of the workpiece being disposed adjacent the edge of the plate 64 and the dogs 54 are in abutment with the bumper 65 so that in the next operation, the plate 64 will be advanced with the workpiece supporting platen to maintain engagement of the plate td with the ngerpiece 63.

The next operation consists in raising the work supporting platen into the position shown in Fig. 16, which operation causes the gripper linger 60 of the workpieces to be raised and moved through the cut-outs |00 in the card 58, thus raising the flanges 99 of the card and these flanges together with the ngers 60 extend into the workpiece receiving apertures or recesses 91 of the card holding platen.

Next, the workpiece supporting platen is moved further to the right as seen in Fig. 17, extending the fingers 60 to a point overlying the card 58 beyond the limits of the flanges |0| and with the fingerpieces 63 at a point to the right of, and clearing the flanges |02 of the card, the ngerpieoes 63 being, at this point extended into the recesses or apertures 97, whereupon the workpiece supporting platen is moved slightly to the left. as shown in Fig. 18 to bring the finger- `pieces 03 over the flanges |02, establishing the complete locking or coupling engagement of the workpieces with the card. The workpiece supporting platen 3l isuthen moved downwardly into the position shown in Fig. 19, completely freeing the workpiece supporting platen from the workpieces supported on the card, whereupon the workpiece supporting platen is then returned to the position shown in Fig. 14, and the above operation is again repeated.

. Immediately upon return of the workpiece supporting platen to the position shown in Fig, 14, suction is released from the passages 9S of the platen and the card with the two curlers mounted thereon will drop into a suitable receiver` in the machine or be guided from the machine to a collecting or packaging station.

. Considering Fig. 1 of the drawing, it will appear that the operation of the card delivery slide 'l5 is slightly retarded with respect to return operation `of 4the workpiece4 supporting platento the position shown in Fig. 1 to give suiiicieritY time for release ofA the card before advancingv a second card to the carding station. Y

From the foregoing, it will be apparent that in the operation of' each unit of the machine, the card is nrst delivered to the assembly station, held rat this station by the suction holding means employed, then the workpieces on the workpiece supporting platen are moved to the position beneath the card holding platen and then the workpiece supporting platen is given a partial raised movement, then a further raised movement whilev the platen is. further advanced. This last operation provides the one coupling engagement of the workpieces withvthe card, then the workpiece supporting platen isf given a partial reverse movement to further lock the workpieces with the card,y after which the platen is lowered,- leaving the Workpieces on the card and thenV theworlrpiece supporting platen is returned to its loading station, whereupon suction is broken to the card, releasing the card for delivery into the machine. immediately after the release of one card, another card is advanced tov the card holding platen, and the above operation is repeated.

The control device 55 including the sliding plate E4, which operates upon the article, in moving part thereof into extended position, may be said to comprise anv article conditioning means which positions the article for assemblage with the card or holder.
