37 Claims.

This invention relates to apparatus for mechanically applying wrapper bands and/or end caps to rolls of paper or any other material over a wide range of diameters and lengths.

An object of the present invention is the provision of means for mechanically applying wrapper bands to rolls, such as paper rolls, whereby the latter are uniformly wrapped in a minimum Of time.

Anotherobject is the provision of means for quickly and easily applying end caps to rolls, such as paper rolls without the necessity of manual labor other than keeping the apparatus supplied with caps and, if necessary, glue.

Under the present generally adopted wrapping procedure, a large sheet of wrapping paper somewhat longer than the length of the paper roll is wrapped over the entire roll and glued in place.

Due to the wrapper being longer than the roll,

it projects beyond both ends of the roll. A

circular sheet of wrapping paper slightly smaller `in diameter than the roll is placed over the roll end and the projecting ends of the wrapper folded down over it. `It is then usual to apply by hand glued bands of wrapping paper around the circumference of the roll at either end which project beyond the ends of the roll. The number of bands so applied varies with different wrapping requirements and different numbers of bands may be applied to opposite ends of the same roll. In some instances one or more bands are wrapped around the circumference of the roll at points `intermediately situated between the two ends.

approximate size of the ends of the roll are covered with glue on one side and attached to the face of the platens by means of a pin, clip, or other device. Both of these operations are carried out by hand. The platens carrying the caps move inwardly and exert pressure on the ends of the roll, and after this pressure has been maintained for a predetermined interval until `the glue has bonded, the platens are retracted and `the roll discharged.

While this machine is particularly designed for After the The roll, lying on handling rolls of paper, and is so described herein, it is to be understood that it may be used for handling rolls of any other material requiring wrapper bands and/or end caps.

This apparatus is intended to handle paper rolls of varying lengths and diameters after the main roll wrapping has already been applied in any convenient manner. Of course, rolls requiring wrapper bands and/or end caps and not having the main roll wrapped, may also be handled.

While the machine may be adjusted to handle rolls of different lengths, it usually is set up to handle rolls of a given length in runs or batches in order to avoid unnecessary waste of time in changing the adjustment of the machine for consecutive rolls of different sizes.

A roll of paper directed to the machine is held until the cycle of operation permits it to be moved into position for the first operation. At this time, a band of wrapping paper is applied to either or both ends of the roll and intermediately of the ends, as required. The roll is rotated around its longitudinal axis a pre-determined number of times for each band in order to apply the required number of layers of the band. Each end band projects outwardly from its end of the roll. The roll is then ejected from the wrapper portion of the machine and held ready for the crimping stage.

When the crimper is ready, the roll is moved into position between two crimper head assemblies which have been moved outwardly away from each other to enable the roll to be moved into place. The crimpers are then moved inwardly against the ends of the roll. Each crimper has a plurality of crimper plates which function somewhat in the same manner as an iris diaphragm. These plates are hingedly mounted on a ring and may be swung towards and away from the ring centre in substantially the same vertical plane. When these plates are swung inwardly, they press or crimp the protruding end of the adjacent wrapper band against lthe end of the roll. Means may be provided for causing the crimper plates to operate while their head assemblies are still spaced a short distance away from the roll end, and after the wrapping bands have been crimped, the assemblies may be moved towards the roll ends to press the folded bands against the ends of the paper roll, giving them a set.

The roll is now ready to have the caps applied to the ends thereof. The roll is moved into position between two capper assemblies which have been moved outwardly to positions which are spaced from the ends of the roll when the latter is in position between them. The glue is applied to one surface of a cap for each end of the roll, and the cap is moved into position against the inner surface of a capper assembly lying substantially parallel with the adjacent roll end. Then the capper assemblies are moved inwardly of the machine until the caps are pressed firmly against the ends of the roll where they are held for sumcient time to allow the glue to adhereto the crimped bands on the roll ends.

An example of this invention is illustrated in the accompanying drawings, in which,

Figures 1 and 2 constitute a side elevation of the machine from the right to the left thereof, respectively,

Figures 3, 4 andr5 constitute a plan view of the machine from the right thereof, respectively.

As this machine is particularly designed for handling rolls of Vpaper which are very heavy, it is shown in a well lil below the floor level Il. However, it is to be understood that it may be located on a oor with suitable means for lifting'the rolls up on to it.

A suitable conveyor i 5, see Figures 1 and 3,

` is provided for moving the paper rolls into position at one end Vof the machine. Each roll extends longitudinally of the conveyor and it is moved on to a high end of a sloping deck i8 by any suitable mechanism, such as a hydraulically controlled roll kicker i9, the construction of which is well-known in the paper making industry. The roll moves under the force of gravity along the deck until it comes to rest upon a roll stop and loader 22. These devices are also well known in the industry, and they consist mainly of a tiltable plate 23 which is normally set at an angle to prevent a paper roll from moving down the deck. When it is desired to free the roll,

the plate is tilted forwardly by suitable pneufmatic or hydraulic means 25, linkage 25 and shaft 25a upon which the plate is mounted, to permit 'the roll resting on it to move down the deck. The deck E8 directs each roll to the band applicator generally designated by the numeral 25, where it comes to rest.

.At this point, it may be stated that when Vthe machine is designed for handling rolls of diirerent lengths, the remainder of the machine beyond the band applicator is constructed in two side elements which .may be moved towards and "away from each other to fit the rolls lof different sizes. As each side of the machine is a duplicate of the other, only one side will beV f generally described for the sake of clarity.

Wrapper hemd applicator The applicator '26 appears in Figures 1, 3 and,

. and includes a pair of drums 35 and 3l which extend transversely of the machine. These drums lieV in substantially the same horizontal plane fand are spaced apart so that when a paper roll moves on to them, it stops moving and is completely supported by them, see Figure 6. Suit- A roll ejector bar 42 extends transversely of the machine between the drums 35 and 3| land is normally positioned below the upper surfaces of these drums, as clearly shown in Figure 6. The upper surface of the ejector bar slopes transversely of the bar so that the rearward edge 43 thereof is slightly higher than the forward edge. With this arrangement, the edge 43 of the ejector is located to one side of the vertical plane passing through the centre of the paper roll resting on the drums 39 and 3i so that upward movement of the ejector will move said roll over the drum 3l.

The ejector 42 may be raised and lowered in any desired manner. n this exampie, hydraulic or pneumatic cylinders i8 are located at opposite sides of the machine and the rams is thereof project upwardly and are connected to extensions 5E projecting outwardly from the ends of the ejector.

rlwo different mechanisms for supplying wrapper bands for the paper rolls are illustrated in the drawings, but it is to be understood that these may be interchanged or the same type of mechanism may he used for applying each band. A carriage is located at -each side of the machine for holding the mechanism for :supplying the wrapper band to an end of the paper roll. Each carriage is mounted on gear wheels 5t running on racks 5? extending transversely of the machine so that the carriage may be shifted back and forth. The outer gear wheels 55 of the carriage are mounted on a shaft58 which extends from end to end of the carriage, saidshaft having a gear 59 riXedly mountedthereon, `see Figures 1 and 3, which'is rotated'by a pinion Sii mounted on the shaft of an electric motor'l.

The carriage 55 is provided with means' for mounting one or more paper rolls 65. The'axial length of each roll determines the" Width of thel wrapper band which is applied to the paper roll. A strip of paper from the desired roll 55 extends under an idler 67 and up between a feed roll t8 and the drum 3l. This feed roll is Vcarried by supports 69 projecting upwardly. from a glue container It which is pivotally mounted at H on the carriage 55. The pivot point 'H is located at one edge of the bottom of the glue container, and the ram 12 of a hydraulic cylinder 13 is connected to the opposite side of said bottom. The lower end ofthe cylinder 'i3 is pivotally mounted at l' in the carriage.

and bears against the roll 68.

When the ram 'I2 of the cylinder 'I3 is retracted, the feed roll 68 is spaced from the drum 3l, and when said ram is moved outwardly, the container 'l0 pivots about the point 'il to move the feed roll towards the drum, at which time the wrapper band is pressed against said drum.

When it is desired to^feed the wrapper band to the paper roll, the drums 30 and 3| are rotated in the direction of the arrows 18. see Figure 6, to turn thel paperroll resting on them. The cylinder 'I3 is operated to cause the feed roll 68 to press the wrapper band against the drum 3l to cause it to move'with the latter. The appli- A glue applicator or rollV 'i5 is rotatably mounted in the contaner 75 `paper roll. applicator 92, it receives the glue, and the strip is fcator 16 supplies glue to the surface of the feed roll which, in turn, applies the glue to the `wrapper band. As the wrapper band passes between the fdrum 3| and the paper roll, it is pressed on to said roll and the operation continues until the desired number of layers of the wrapper band have been applied to the roll. then stopped and the ejector 42 is raised to move lthe paper roll over the drum 3| on to the high end of a sloping deck 82 located at the discharge iside of the band applicator. -moves on to this deck, the paper band at the roll end is servered in any suitable manner, such as -by a serrated cutter 83 located at the end of the The drums 30 and 3| are As the paper roll deck facing the drum 3| near each end of the latter.

`As stated above, there is a wrapper band feed mechanism at each side of the machine. If it is desired to apply a wrapper band to the paper `roll anywhere between the ends thereof, a duplicate I-Iowever, in this example, means 4ready described. For this purpose, a carriage 81 may be provided beneath the deck I8, said carriage being shiftable laterally of the machine in 4the same manner as the carriage 55. The carriage 81 is adapted to support a roll of wrapper band stock 89. A strip from this roll extends under lan idler roll 9| and over a glue applicator 92 rotatably mounted in a glue container 93, said container being pivotally mounted on the carriage at 94, see Figure 6. The paper strip continues over a nned feed roll 95 also carried by `the container 93, and around the drum 3D. The

ram 95 of a pneumatic or hydraulic cylinder 91 Yis connected to the container beneath the feed roll and is adapted to move said roll towardsand away from the drum 39. When the latter drum 'isrotated and the feed roll presses the strip of paper against it, the wrapper band is fed to the As the paper strip 'moves over the pressed against the paper roll by the drum. A suitable cutter, such as a serrated cutter 98, ex-

tends along the ejector 42 at the edge 43 thereof "and facing the drum 3| so that when the ejector is operated to move the roll on to the deck 8,2,

the wrapper band is cut off by the cutter as the "roll moves towards the deck.

With this applicator, the paper bands may be applied to either or both ends of the paper roll and to any portion thereof between said ends. If it is desired, the number of layers of the band Vwrappers may be the same or different at each position. For example, the paper roll may require 7 thicknesses of the wrapper band at one end, 5 thicknesses at the other, and 4 in the middle. in this case, the band applicator drums are started and the band material fed to one end of the paper roll thereon only. When the paper roll has made -hold more than one paper roll at a time. In any= same time.

case, a roll stop and loader |02 similar to the 4stop and loader 22 is provided adjacent the end of this deck remote from the band applicator. This device retains the paper rolls on the deck until one is required for the next operation.

Band crimper assembly This assembly, see Figures 2, 4, 7 and 8, has a combined stop and unloader I D located centrally thereof so that a paper roll resting on it is centred on a transverse centre line or axis of the assembly, see Figure 4. This stop and loader may be the same as the stop and loaders 22 and |82, although the one shown in the drawings is slightly diierent since it is intended to carry the full load of the paper rolls. This device includes a pair of dished supports ||4 which are pivotally mounted at one end at ||5. The opposite ends of these supports are carried by a horizontal shaft 6 which is pivotally mounted in and carried by the upper end of the ram ||1 of a hydraulicor pneumatic cylinder H8. Normally the ends of i the supports `carried by the ram are lower than their opposite ends so that a paper roll from deck 82 may move on to but not past this device. When it is desired to unload the roll, the cylinder is operated to move its ram outwardly and raise the adjacent ends of the supports to tip the paper roll off the device.

A crimper is located at each side of the machine, and as these are identical, only one will be described in detail. The crimper cons-ists of a relatively long air or hydraulic cylinder |25 having a piston rod |25` extending towards the centre of the machine on the centre line ofthe 'crimper assembly. A vertical base plate |21 is mounted on the outer end of the piston rod, said base plate being larger than the end of the largest paper roll to be handled by this apparatus. This base plate has wheels |28 riding on tracks |29 which extend across the machine.

A large gear |34 is rotatably mounted on the piston rod |23 against the outer surface of the bas-e plate. A plurality of pinions |35 are arranged around and mesh with the large gear. Each of these pinions is mounted on a short shaft 33 which extends through the plate |21 and is `journalled in a bearing |31 supported by and pro- 'jecting inwardly from the plate.

A crimper plate |40 is mounted on the inner end of each shaft |36. Each crimper plate may be of any desired shape and it is mounted adjacent one end thereof on its shaft. These crimper plates are arranged in a circle around the axis and normally are swung outwardly from said axis, as shown in Figures 2 and 7. Suitable means is provided for rotating the gear |34 to swing the `crimper plates inwardly towards said axis. `This `operated to move one rod inwardly and the other outwardly, the pinions connected to the levers |41 are rotated, thus causing the large gear |34 to move so that all pinions are rotated at the This swings the crimper plates inwardly or outwardly depending upon the direction of movement of the gear.

A'|54 is mounted on the inner surface of the base plate |21 centrallyfthereoi and has .a piston rod |55 V`,projecting inwardly of the machine, upon the free end of which is mounted a bumper plate |56. The piston rod |55 is normally extended and the bumper plate |56 lies in a plane slightly closer to the centre of th-e machine than the plane of the crimper plates hill as clearly shown in 'Figure 4. When the rod |55 is retracted, the bumper |5615 withdrawn `toY the outer side of `the plane of the crimper plates.

Aseach crimper plate is only supported adjacent its linner end, atleast one roller |59 may `be mounted on the base plate |21 immediately behind each crimper plate when the latter is in its These rollers may just touch lAt the time a paper roll is moved on to the "stop and unloader |59, the piston rods |26 of the Acylinders |25 are retracted so that the crimper plates |46 ar-e withdrawn clear of the paper roll 'and said plates are in their outer positions.

flren the .cylinders |25 are operated to move the crimper assemblies towards the ends of the paper .'roll. It will be noted that the bearings |31 are arranged on the base plate |21 so that they clear Vthetperiphery of the largest roll to be handled :by the machine. Acontacts the roll end, the movement of the When the bumper plate |56 crimper assemblies is stopped. The vertical plane yofthese plates is spaced a little from the roll end,

but the plates overlap the portions of the wrapper bands which project from the ends of the roll. The cylinders |45 are actuated to cause the large gears |34 to rotate to swing the crimper These plates fold the pro- -pressure in the centre cylinder |55 is released,

and .the cylinders |25 are actuated `to press the crimper plates firmly against the roll ends, thus At this time,

The cylinders |25 vare now actuated to withdraw the crimper .plates from the roll ends, the cylinders |45 are actuated to return the crimper plates to their outermost positions, and'thepressure is returned to the cylinders |513 to move the bumper -plate |56 beyond the crimper plate plane.

VThe .unloader Hi) is operated to direct the paper lroll on to the high end of a sloping deck |62 vwhich directs the roll to the end cap applicator.

Capper l l-The deckV |62 directs each paper roll onto a combination stop and unloader |65 mounted beneath the transverse centre line |66 of the capper assembly shown in Figures 2, 5, 9 and 10. This device is similar to the combination stop and unloader H of the crimper assembly.

Suitable means is provided for applying glue toone surface of caps |69, moving these caps :into position and then applying them to the opposite ends of a paper roll on the stop and unloader |65. For paper rolls, the caps |69 are round and .of approximately the same diameter as the roll.

Astack of these caps is maintained in a rack |12 Each rack is located to one side of the centre line |66 of the capper, as clearly shown in Figure 5, and is mounted Yonta carriage |13 having wheels |14 riding ontracks which extend longitudinally .of the machine, `One or more flexible suction pipes |13 extend from vacuum apparatus. .not shown, and each has a nozzle |19 which :is .dirrected towards and rests upon the uppermost cap near the edge thereof closest to the centre line |66. Each nozzle is supported by a cross bar |82 which is carried at its opposite ends by aV pair of substantially horizontal arms |83 Whichare pivotally mounted on a shaft |64 whichisfsupported by brackets |65 extending upwardly -from the rack. Cam discs |86 are mounted near :and below the arms |83 eccentrically on a common shaft V|89 which has a sprocket |90 mounted on one end thereof connected by chain 9| to 1another sprocket |92 mounted on a shaft |93 of Yan electric motor |94. Each arm has a roller |96 mounted thereon immediately above one ofthe cams |98 so that when the latter is rotated, it swings the arm upwardly. Each nozzle .|19 extends to and is secured to a coupling 266 which is carried by and fixed to the cross bar |.82,.and the latter rotatable in bearings 29| on the ends or the arms |83. A pair of L-shaped supports 295 having the upper ends of their Vertical sections iixedly secured to the bar |82 at 206, see Figures 5 and 9, carry a. transverse shaft 269. at the outer ends of their horizontal sections. vA roller 2id is mounted on each end of this shaft beneath a substantially horizontal cam track '2|\|.

With this arrangement, each time the inner ends of the arms |83 are raised by the cams |88, the rollers 2|@ move in a horizontal direction beneath the cam tracks 2 causing the VLeshaped supports 205 to rotate the cross bar-|52 atthis time. The nozzles |19 are lifted by thisaction and the rotation of the cross bar `causes the lower ends of these nozzles to swing towards the centre line of the capper |66. Suction in the pipe or pipes |15 causes the nozzles to lift the uppermost cap |59 and the swinging movement of the nozzles moves the edge of saidcap into the nip between two feed rolls 2|5 locatedfadjacent said nozzles. The uppermost roll is rotated by the shaft |93 of the motor |915 and presses against the lower roll. These rolls move the cap over a table 2|5 to a glue applicator 2|1. Normally when applying glue to a surface of an article, the article is moved between a pressure roller and a glue applicator roller. However, in this case, each cap |69 is circular in shape so that vfor a'large percentage of thetime the pressure roller will be bearing against the glue v'applicator .roller and would become covered withglue in a having aplurality of spaced grooves 22| formed inthe periphery thereof. This roller rotates in a container 222 which holds a quantity of glue. Thepressure roller is in the form of a plurality of spaced discs `225 mounted on a shaft 226, 'each disc being located above a groove 22| in the roller 220, see 1Figures 5 and 10. There Yis suiiicient space between the discs and the periphery of the roller to enable a cap to pass therebetween. A notched scraper 228 has iingers 229 fitting into the grooves 22| to keep the latter cleared of glue. The main portion of the scraper' controls the thickness or" the layer of glue on the periphery of the applicator roller. The Vdisc shaft 225 is rotated in any convenient manner. In this eriample, a sprocket 232 mounted on one end of the shaft |93 on which the upper pressure roll 2|5 Ais mounted, is connected by a chain 234 to the adjacent end of the roll 220, see Figure 5, so that the latter roll rotateswith the pressure roll discs 225.

A cap passing between the roller 220 and the. discs 225 has a coating of glue applied to its lower surface, excepting the portions thereof passing over the roller grooves. Each cap is received by a series of rolls 240, each of which consists of a plurality of spaced discs 24| mounted on a shaft 242. Each of these shafts has a sprocket 243 connected by a common chain 244 to a single sprocket 245 mounted on the shaft 238. The discs 24| are in line with the grooves 22| 0f the applicator roll 226, so that the portions of the lower surfaces of each cap which are devoid of glue come into contact with said discs. If desired, suitable Scrapers may be provided for removing any glue which may adhere to the discs. A plurality of fingers 248 project upwardly adjacent the edge of the table formed by the discs 24| remote from the glue applicator.

It will be noted that all the mechanism described so far for handling the caps |69 is mountedon the carriage |13. Suitable means illustrated at 255 is provided for shifting the carriage longitudinally of the machine. The reason for this is that it is necessary to have the centre of each cap resting on the discs 24| lying in the vertical plane of the centre line |66 of the capper. Ascaps of different sizes are used in this machine, the carriage |13 is shifted lon` gitudinally` ofthe machine to position the different sized caps in the right place. i

A relatively long air or hydraulic cylinder 265 is mounted on the outer side of each table made up of discs 24| and on the centre line |66of the capper. A piston rod 266 extends inwardly from the cylinder towards the centre of the machine and has a vertical platen 261 mounted on its inner end. This platen is larger than the end of the largest roll to be handled by the machine, and it has wheels 268 riding on transverse tracks 269 so that the platen may be moved towards and away from` the centre of the machine by the piston rod. i

`A hollow., arm 214, see Figures 9 and. l0, is mounted in the platen and has its face iiush with the inner face 215 of the latter. A plurality of openings 216 are formed in the inner face of the hollow arm 214. This arm is carried by levers 219 at its lower end which are pivotally mounted on a shaft 280 carried by bracket 28| extending downwardlyfrom the platen. The opposite end` of one of these levers is connected to the piston rod 284 of an air or hydraulic cylinder 285 pivotally mounted on the back of the platen by means of a bracket 286. The arm 214 normally lies within the platen in a substantially vertical plane, and when the piston rod 284 is retracted, i

this arm is moved into a substantially horizontal position, as shown in dotted lines in Figure l0, immediately above the discs 24|. Actually, at this time, the hollow arm engages a cap |69 resting `onsaid discs. A suction hose 290 is connected to the bottom of the arm 214,.,said hose extending to suitable vacuum apparatus, not shown.

In operation, the cams |88 raisethe arms` |83 tolft the uppermost cap |69 `from the pile and insert the` edge thereof between the pressure rollers `2|5. These move the cap to the glue applicator, and the power driven discs 225 and roll; 220 thereof move the cap with` its layer of glue on tothe table of discs 24|, the pins 248 stoppingthe cap in the correct position. When a roll of paper reaches the stop and uploader |65, the platens 261 are drawn outwardly as far as possible. The cylinders 285 of the platens are actuated to cause the hollow arms 214 to move clown on to the caps in position on the table discs in front of them. When these arms are returned to their normal vertical positions, the suction therein lifts the caps with them. Then the cylinders 265 are actuated to move the platens inwardly against the ends oi the paper roll to press the caps against the crimped wrapper band. Pressure is maintained long enough to ensure the caps remaining in place, and then the platens are withdrawn to their outermost positions. The unloader |65 is then actuated to direct the paper roll on to the upper end of a sloping deck 29| which guides it away from the machine.

Controls and general operation In order to co-ordinate all the component parts of this machine, a system of inter-locking controis is installed. These controls are all standard equipment and need not be described in detail herein. It has been found that the band application is the slowest operation so that all other parts of the equipment are timed from the band applicator. The number of revolutions made by the paper roll when the band o1' bands are being put on and the length of time the roll remains in this section of the machine may be controlled by an operator. However, the operation of the remainder oi the machine will be completely automatic. Paper rolls are supplied to the machine by the conveyor I5. At the right time, the roll kicker le is operated to moveeach roli on to the sloping deck I8. The stop 22 holds the roll on the deck until the band applicator is ready to receive it. Then the loader 22 is operated to free the roll to allow it to move on to the drums 66 and 3i of the band applicator. At this point, the required bands are applied to the roll at either or both ends and/or any desired point between said ends. When this is completed, the ejector i2 is operated to move the roll on to the sloping deck 82 where it is retained by the stop |02.

When the loader |62 moves a paper roll on to the stop H6 of the crimper, cylinders |25 are actuated to move the crimper assemblies towards the roll ends, and the central cylinders |54 are operated to extend the bumper plates |56 beyond the planes of the crimper plates. As soon as the bumper plates engage the ends of the roll, the crimper plates are swung inwardly to crimp the wrapper bands over the roll ends. Then the bumper plates |56 are withdrawn to permit the crimper plates to press against and set the crimped bands. As the crimper assemblies are withdrawn from the roll, the crimper plates are returned to their outermost positions. The unloader H6 discharges the roll from the crimper and said roil moves down the deck |62 on to the stop |65. Just prior to this, caps had been moved through the glue applicator and picked up by hollow arms 214 of the platens 261, the latter being in their outermost positions. The cylinders 265 are actuated to move the platens against the roll ends. The suction is cut off from the hollow arms and, after a predetermined time, the platens are withdrawn to their outermost positions, by which time new caps are resting on the tables of discs 24|. The unloader |65 is now raised to discharge the roll on to deck 29| and out of the machine.
