9 Claims.

This invention appertains to the making of reels, spools and the like, and more particularly to a novel machine for forming paper or cardboard spools of the type commonly used in the ribbon industry.

One of the primary objects of this invention is to provide a device for continuously forming spools in which means is provided for feeding cylindrical cores in proper timed relation to a mechanism for applying end discs thereto to complete the spools.

Another important object of the invention is to provide means for applying an adhesive to the terminals of the cores just prior to the feeding of the end discs to the cores for connecting said end discs to the cores.

A further object of the invention is to provide means for centering the discs relative to the cores and for holding the discs firmly against the cores until the adhesive has set so as to insure the delivery of a continuous uniform perfect product.

A further important object of the invention is the provision of means for feeding the cores to a feeding wheel or disc and for applying the adhesive to the terminals of the cores during movement of the Wheel with novel means for transferring the cores with the coated terminals to a specially designed conveyor wheel, novel means being provided for feeding the end discs for the spools to the conveyor wheel and thereafter applying and holding the end discs properly centered on the terminals of the cores.

A still further object of the invention is to provide means for delivering the completed spools to a conveyor belt, which in turn carries the spools to suitable packing cases or cartons.

A still further important object of the inventlon is to provide a machine of the above character, which will be durable and eificient in use, one that will be simple to construct and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawings, in which drawings,

Figure l is a side elevational view of the complete machine.

Figure 13 is a front elevational view of a completed spool, parts of the view being shown broken away and in section.

Figure 14 is a transverse sectional view through a completed spool taken on the line [4-H of Figure 13, looking in the direction of the arrows.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my improved core making or assembling machine and the same includes a frame and base it, on which the various parts of the machine are mounted. The frame and base l5 of the machine A can be constructed in various manners, and hence the drawings are merely illustrative of one type of frame and base. As shown, the frame and base embody end side beams I6 and I1, and an intermediate spaced parallel beam l8. These beams l6, l1 and I8 are welded or otherwise rigidly secured to a front beam I9 and a rear beam 20. This forms a rugged, horizontally disposed frame and corner standards or legs 2| are provided therefor. frame and the legs or standards can be braced in any desired way, such as by the use of diagonal brace bars 22. One end of the frame has rigidly secured thereto a fabricated bracket 23 and rigidly secured to this bracket is an upstanding pillar or upright 24. A similar ,upright or pillar is rigidly secured to the intermediate brace beam l8 and the upper ends of these uprights or

pillars

24 and 25 are rigidly connected by a top cross frame brace 26.

Mounted adjacent to the upper end of the frame [5 is rotatable feed wheel 21 for the cores C, which form the hub or body of the completed spools S. These cores C have applied thereto in a novel manner, as will be later described, end discs D. The wheel 21 is rigidly fastened to a cross shaft 28, and this shaft is supported in suitable bearings 29 carried by the uprights or

pillars

24 and 25. The wheel 21 is of a special construction and preferably includes spaced parallel circular side plates 30 and these plates are held in their proper spaced position by spacer sleeves 31, on bolts 32, which connect the plates together to form the wheel. The periphery of the wheel is formed to provide seats at equidistantly spaced points for the cores C, and as i1- lustrated, the edges of the side plates are provided with semi-circular notches 33, which form these seats. Hence, the cores are held at spaced points and a wide seat is thus provided. Leading toward the periphery of the wheel and preferably at the rear side thereof, and adjacent to its upper end, is a feed chute 34 for the cores C, and this chute can lead from a hopper (not shown) or any suitable source of supply. The wheel 21, see Figure 3, rotates in a clockwise direction and as a seat passes the open forward end of the chute 34, a core C will be deposited in the seat and the core will be carried around with the wheel. To prevent displacement of the cores from the wheel during the turning movement thereof, an arcuate guide plate 35 extends partially around the wheel and forms a partial housing therefor. The plate extends from the chute around the wheel and terminates below the wheel approximately in line with the vertical diametric center of the wheel, and the lower end of this guide plate has formed thereon a downwardly curved arcuate guide lip 36, the purpose of which will be later set forth.. The guide plate is supported in any desired way, such as by the use of depending brackets 31 extending from the top cross beam or brace 26. The guide plate is also rigidly fastened to the upper end of the chute 34. If preferred, the chute itself can be supported at its front end from the frame [5 of the machine, and as shown in Figures 1 and 3, brackets 38 can be extended from the

side uprights

24 and 25 toward the chute. These brackets in turn support a cross brace 39 which extends under the chute.

Positioned directly below the feed wheel 21 is a conveyor wheel 40, which receives the cores from the feed wheel after the terminals thereof have been coated with the desired adhesive. By

The

referring to Figure 3, it can be seen that the conveyor wheel 40. rotates in a counterclockwise direction and in an opposite direction from the feed wheel 21. The conveyor wheel 40 is rigidly secured to a cross shaft 4|, which is arranged in parallel relation to the shaft 28, and this shaft 4| is rotatably mounted in suitable bearings 42, carried by the

uprights

24 and 25. The wheel 40 is also of a special construction and includes a pair of inner spaced parallel circular plates 43 and an outer pair of spaced parallel circular plates 4-4. The plates 44 are of a greater diameter than the inner pair of plates 43. All of the

plates

43 and 44 are held in their proper spaced position by spacersleeves 45 fitted on bolts 46 which rigidly connect the plates together. The inner pair of .plates 43 have their peripheries notched at equidistantly. spaced points to form seats 41 for the cores C and as the upper and

lower wheels

21 and 40 turn, the peripheries of the inner pair of plates 43-ride in close proximity to the peripheries of the plates 30 forming the wheel 21. The edges of the outer pair of plates 44 are disposed on opposite sides of the edges of the wheel 21, as is best shown in Figure 2 of the drawings. The inner pair of plates 43 of the wheel 40, has the same number of seats 41 as the wheel 21,- and means is'provided for holding the cores in the seats '41 for a part of a revolution of the wheel 40. This means includes a circular guide plate 48 and the guide plate 48 extends around the rear half-of.the Wheel 40, as best shown in Figure 3. The guide plate 48 can be held in position-by the use of a suitable bracket 49. The upper end of the guide plate 48 extends between the plates 30 of the wheel 21 and terminates just above the guide lip 36 and the upper end of the guide plate 48 is provided with an upturned guidelip 50. The guide lips 36 and 50 function to permit the falling of a spool from the lower part of the feed wheel 21 into a seat of the wheel 40 and the guide lip 50 func tions as a stripper to insure the placing of a core from the wheel 21 into a pocket of the wheel 40. The lower end of the guide plate 48 has formed thereon a downturned guide lip 5|. Arranged in spaced relation to the downturned guide lip 5| is an arcuate stationary stripper plate 52 and this stripper plate 52 rides between the inner pair of circular plates 43 and insures the stripping of a completed spool S from the conveyor wheel.

Directly below the conveyor wheel is a conveyor belt 53 for carrying the completed spools away from the machine. As shown, the conveyor belt 53 carries flights 54 for engaging the spools and this conveyor is carried by the frame I5 of the machine and extends rearwardly therefrom. The conveyor 53 can be utilized for carrying the spools directly to a suitable packing carton (not shown), if such should be desired.

The conveyor wheel will be later described more in detail and means 55 is provided for applying an adhesive to the terminals of the core C during the carrying of these cores by the wheel 21 to the wheel 40. Means 56 is also provided for carrying the end discs D to the coated terminals of the cores C carried by the wheel 40.

The means 55 utilized for applying the adhesive to the ends of the cores C includes a pair of pots 51 arranged in front of and on opposite sides of the wheel 21. Rotatably mounted in each pot is an adhesive pick up roller 58, a transfer roller 59 and an applying roller 60. The applying roller 60 can have engaging the same, a doctor blade ill for removing excess adhesive therefrom. The pick up rollers 58 are partially immersed in the glue pots and the rollers 59 engage the rollers 53 and the applying rollers 69. The applying rollers Fill extend out beyond the pots and are arranged in the path of the cores C and as the cores are carried down past the rollers 50, the rollers Kill function to coat the outer ends of the cores with the adhesive. The drive means for the various rollers will be later described and it is to be noted that the glue pots can be supported in any desired way, such from an intermediate horizontal frome which in turn is rigidly connected to the uprights or

pillars

24 and 25. Obviously, as the feed wheel 21 rides between the applicator rollers 68, these rollers apply the desired quantity of adhesive to the ends of the cores C carried by the feed wheel.

Directly below the adhesive applying device 55 is a pair of troughs 63 and $4 for the end discs D. The troughs can be of a semi-cylindrical shape and the same extend transversely across the front of the machine and the inner ends thereof terminate in front of and on each side of the inner carrier plates 33 of the conveyor wheel ill. The troughs 63 and M extend into feeder heads 55 and St, which in effect, form continuations of the

troughs

63 and 64, and the heads have formed on their inner ends inwardly directed guides 67 and Q38. These guides lead directly toward the periphery of the conveyor wheel ii] and are substantially in alignment with the outer plates Ml of the wheel All, for a purpose which will later appear, The guides 61 and 58 each have downwardly inclined guide slots 69, through which the end discs D are adapted to roll, as also will later appear. The troughs 63 and. 54 receive stacks of the end discs D, as is best shown in Figures 4 and 6, and the end discs are normally urged toward the inner ends of the troughs and out the

heads

65 and 56 in front of the guide slots $9. .Any desired means can be provided for urging the discs toward the inner ends of the troughs, and as illustrated, followers H3 are slidably mounted in the troughs and the ends of the followers have secured thereto pull cables H, which are trained over idle pulleys '52, carried by the heads 65 and 6t. The

lower ends of these cables have attached thereto weights ill. Guide rods Hi can be carried by the opposite sides of the troughs for facilitating the guiding and easy sliding of the followers ii! in the troughs. The ends of the troughs can be closed by end caps 15, and each of the end caps carry a pivoted latch l6 and during the loading of the troughs with the discs D, the followers can be pulled back against the pull of the weights 7,3 and latched in their retracted position by the latches 16. In other words, the latches are hooked over the followers.

The troughs can be rigidly held in place on the frame l5 of the machine, in any desired way, and as illustrated, brackets l! are carried by the horizontal. supporting frame 52, which carries the glue applying mechanism 55. Operating in conjunction with the

heads

65 and 66, is a pair of spaced wiper and feeder arms 11 for carrying a pair of discs at a time to the guides 61 and 63 from whence they are conducted to the conveyor wheel 4B. The arms 1! move together and hence the same are preferably rigidly connected by a brace bar 78 and the arms are keyed or otherwise secured to a rock shaft 79, which extends transversely of the machine below the

troughs

63 and 64. The rock shaft is mounted in suitable bearings 80, carried by the lower ends of the

heads

65 and 66. Other bearings can be provided along the length of the shaft, if so desired, and these bearings can be supported from the frame of the machine. As shown, an upstanding bracltet arm 8| is secured to the frame adjacent to one end thereof, and adjacent to the outer end of the rock shaft, and this end of the rock shaft has keyed, or otherwise secured thereto, a crank 82, which forms a part of the operating mechanism for the wiper and feeder arms ll. This mechanism will be later described. The

outer faces of the arms 17 ride in close engagement with the inner ends of the

heads

65 and 66, and the outer faces of these arms are provided with pockets 83 and the pockets are just the thickness of a disc D. The inner ends of the pockets are open and as the arms 7'! sweep past the troughs, a pair of discs are stripped off of the troughs and are carried to the guide heads 6? and E38, and these discs are then rolled into the guideways 69 (see Figures 3 and 6).

Special means is provided on the conveyor wheel M for receiving the pairs of discs from the guides 6'! and (it, and for then applying the end discs to the cores carried by the conveyor wheel til, which cores have already been coated with the adhesive. Now referring to the means for receiving the pairs of discs D from the guideways, the outer pair of plates i l have mounted thereon at equidistantly spaced points and on opposite sides of the seats 4'! of the inner plates 43, slide plungers 84. These slide plunger-s 34. extend through the plates Ni and the plates are preferably provided with guide sleeves 85 for the plunger. The inner ends of the plungers have formed thereon, or secured thereto, disc receiving heads 85 having open-ended pockets 81, substantially the thickness of a disc. As the conveyor wheel 40 rotates, a pair of heads is brought in alignment with the guides 61 and 63 so that a pair of discs can roll from the guideways into the pockets B1. The inner ends of the pockets have communicating therewith, openings 85 which have a diameter substantially the same as the diameter of the cores C, so that the cores will be centered in the heads 88 and centered relative to the pair of discs carriedv by heads. The outer ends of the plungers 53 5 c anti-friction rollers 59 and the plungers normally urged outward with the heads 8% in engagement with the inner surface of the M by expansion coil springs 9%. These coil springs 90 are placed on the plungers and the inner ends of the springs bear against the guide sleeves 85 and against a washer or cross pin ti carried by the outer ends of the plungers. The inner faces of the plates M have rigidly secured thereto guide strips 92 and these strips have their trailing edges arcuately curved downwardly, as at 93, toward the pockets 8'? in the heads 86, so that as the discs roll down the guideways 69, the same will strike this curved guide surface and be directed into the pockets through their open mouths.

Disposed on opposite sides of the conveyor wheel M3 in proper spaced relation to the outer plates 44 are cam shoes 9d. These cam shoes 94 are rigidly held in place by means of supporting bolts 95, which extend to and thrcugh parts of the frame 15. The shoes 9% can be in the nature of semi-discs and the leading ed es thereof are beveled as at 96, see Figures ll. 12, to facilitate the camming in of the plungers 84, as the plungers are carried with the conveyor wheel 40 past the shoes. These shoes are arranged at the rear half of the conveyor wheel and as a pair of plungers carrying a pair of discs reaches the upper part of the shoes, the rollers 89 will engage the curved cam surfaces 96 of the shoes and the plungers 84 will be forced inwardly, moving the heads 86 toward a core and the discs D carried by said heads 85 will be forced into engagement with the cores and be held in firm contact therewith for substantially one-half of a revolution of the conveyor wheel 40. This will'give a time lapse to permit a partial setting of the glue.

At this time, and before describing the driving mechanism, it will be noted that the machine operates as follows. The delivery wheel 21 and the conveyor wheel 40 operate in proper timed relation relative to one another, so that a pair of pockets 33 in the feeder wheel 21, will be in alignment with a pair of pockets 41, as the wheels move past one another. Hence, as the feeder wheel 21 rotates past the shoes, cores will be picked up by the wheel 21 and deposited in the pockets 33 and held in the pockets by the guide plates 35. As a pair of pockets reaches the bottom of the wheel, the guide lip 50 will strip a core from the wheel and guide the same into a pair of pockets 41 of the conveyor wheel 40. As the cores move past the applicator rollers 50, glue is applied to the ends of the cores and the glued cores are deposited on the conveyor wheel. At a proper time, and as the heads 86 ride toward the guideways 59, the arms 11 are moved past the

troughs

63 and 64 and carry a pair of discs to the guideways 69, and the pair of discs will roll down the guideways toward the periphery of the wheel 40 onto the guide strips 92, and as the wheel continues to rotate, the pair of discs will fall into the heads 85. When these heads, with the discs, reach the cam shoes substantially at the top of the wheel, the heads 85 will be moved inwardly carrying the discs therewith, and the discs will be held in firm contact with a core and when the core with the discs now secured thereto reaches the bottom of the conveyor wheel, the lip 52 will strip the completed spool from the wheel and the completed spool will drop onto the conveyor belt 53. At this time, the open ends of the pockets 81 of the heads 86 will be lowermost. Now, referring to the drive, an electric motor 91 is connected to the frame, such as by the use of a hanger bracket 98. This motor drives through the medium of a belt 99, a speed reducing mechanism I00, which also can be carried by the hanger bracket 98. The speed reducing mechanism includes a drive shaft IOI, which is directly below the main drive shaft I02 of the machine. This main drive shaft is mounted in suitable bearings I03 carried by the frame of the machine. The shaft IOI and the shaft I02, has keyed or otherwise secured thereto, sprocket wheels I04 and I05, which are connected together by a sprocket chain I06. The inner end of this main drive shaft I02 has keyed or otherwise secured thereto a sprocket wheel I01, and a similar sprocket wheel I08 is keyed or otherwise secured to a shaft I09 forming a part of the endless conveyor 53. The sprocket wheels I01 and I08 are connected by a sprocket chain IIO. Hence, the endless conveyor 53 can be constantly driven from the electric motor, as soon as the circuit is closed through the motor, and this conveyor belt need not be in timed relation to the

wheels

21 and 40 and other parts of the mechanism. It is to be understood, however, that the

wheels

21 and 40 and other parts are driven in proper timed relation in the following manner. The shaft or axle M for the conveyor wheel 40 has keyed or otherwise secured thereto a sprocket wheel III. Mounted for free rotation on the main drive shaft I02 is a sprocket Wheel I I2 and the sprocket wheels III and H2 are connected by a sprocket chain II 3. The sprocket wheel II2 can be connected and disconnected to the shaft I02 by means of a clutch II4, the operating handle H5 or which can be located convenient to the operator. Hence, the conveyor wheel is driven directly from the main drive shaft. The shaft or axle 28 for the feed wheel 21 is operatively connected to the shaft 4I by means of a train of gearing H6, and these two

wheels

21 and 40 rotate at the same speed, but in opposite directions. Also keyed or otherwise secured to the shaft or axle M is a star or cam wheel I I1. The star wheel H1 is employed for actuating the crank 82 of the rock shaft 19 in proper timed relation relative to the feed wheel 21, and the conveyor wheel 40. Rockably mounted upon the lower part of the frame I5, as at H8, is a lever I I9, and pivotally connected intermediate its ends to the upper end of the lever H9 is a link I20. The outer end of the link is pivoted, as at I2I to the crank arm 02 and the inner end of the lever carries an anti-friction roller I22, arranged in the path of the lobes or points of the star wheel H1. The lever I I9 is normally urged in the direction of the star wheel II1 by means of a contractile spring I23. As the star wheel rotates, thepoints or lobes thereof will rock the crank 82 and-actuate the pair of arms 11 of the disc feeding mechanism 56.

The means for operating the rollers of the glue applying mechanism can be operated from the main drive shaft I02, and this mechanism need not be timed relative to the operation of .the

wheels

21 and 40 and the disc feeding mechanism, but it is to be understood, of course, that the rollers of the glue applying mechanism should be operated at sufficient speed so that the ends of the cores will be effectively coated. Arranged below the glue pots 51 in suitable bearings is a cross shaft I24, and this shaft is rotated by means of a sprocket chain I25 trained over a sprocket wheel I20, keyed or otherwise secured to the shaft I24, and a sprocket wheel I21, keyed or otherwise secured to the main drive shaft I 02. An idle sprocket I28 can also be provided for this chain to take up slack and to guide the chain around working parts of the machine. Counter shafts I29 are rotatably mounted in suitable bearings carried by the horizontal frame 62, and the shafts are driven from the shaft I 24 by the use of intermeshing beveled pinions I30 keyed or otherwise secured to the countershafts I29 and the shaft I24. The various shafts for the

rollers

58, 59 and 50 of the glue applying mechanism protrude beyond the outer face of the glue pots and have keyed thereto sprocket wheels I3I The countershafts I29 have also keyed or otherwise secured thereto sprocket wheels I32 and sprocket chains I33 are trained about these sprocket wheels I3I and I32 so that all of the rollers will be properly driven.

From the foregoing description, it can be seen that a simple and efficient machine has been provided for expeditiously and continuously applying end discs in proper centered position relative to cores to form completed spools.
