LABELING MACHINE;

Application-filed March 1,

To all whom it may concern 4 7 Be it known that we, CHARLES H. NITsoH and WILLIAM A; VEIGHTMAN, citizens of the United States, and, residents of Logan, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Labeling Machines, of which the following. is a specification. V

The invention relates to machines for applying labels toarticles and packages, and especially adapted for applying revenue stamps to cigarette packages.

Since certain peculiar problems are involved in stamping these packages according'to one general method, and since the in vention provides a satisfactory solution oi? these problems, it'willbe here described as physically embodied in a machine for thatparticular purpose; but it'w ill be evident after considering this embodiment that the invention is adaptable for other uses where some or all conditions are similar.

In order to avoiddifhculties involved in cutting sheets of revenue stamps up into individual stamps, and supplying these from individual magazines for-application to the packages, and certain disadvantages of labeling machines organized in accordance with that plan oi'stamp arrangement, it has been proposed to cut the stamp sheets into strips, each consisting of a plurality of stamps, place thesestrips in stacks in a magazine, feed the strips singly therefrom, cut, the strips to separate the individual stamps, apply adhesive, and then move the individual stamps onward toward applying position, while concurrently moving the stamps apart, to arrange them favorably for application to a row of packages positioned to receive them.

A machine designed to operate on this plan is disclosed in the patent to Fogde and Southwick, No. 1,24%,438, October23, 1917, and a machine or the same general type, with certain variations and improvements is de scribed in the patent to the same inventors, No. l, l35,4 58,-November 14,1922; and the special problems involved in this class of mach nes, so far as they are elucidated in the above disclosures, will not be described herein, except as may be necessary for an understanding of the present improvements.

1922. Serial No. 540,258.

The machines of the above mentioned patents employ pickers or selecting devices, which by the application of suction lift a single stampstripfrom a magazine containing a stack of strips, and retain the strip while it is cut, andtherea'fter the individual pickers or suction heads retain the individual stamps by the same forceof suction (or more properly by external atmospheric pressure in conjunction with lower pressure maintained in the hea'ds) while the stamps are cut, gummed,separated, and moved to application position. l

While these machines represent great im-' provements over hand stamping and previous machines, and operatesuccesstully 'in many respects, they fail to attain .the great est efliciency, for reasons connected chiefly with the pneumatic system of strip selecting and stamp-transport to applying positicn,

are pulled from-the suction heads by the glue roll when glue of desirable strength, or. adhesive quality, is used; in absence of stamps glue is frequently applied to the suction heads, with obvious resulting delay and annoyance; this last difficulty is sought to be avoided, int-he pending application, by devices for releasing the: gluing element from its operative connection in absence'ot a stamp from a suction ihead but these devices, aside from their complication do not avoid the annoyance of stamps falling from the suction heads, and inrespect to the magazine and initial feed arrangement, it is found. that strips frequently adhere together and are removed two at a time by the suction heads; this often results in one strip, being improperly ciutandj thestamps wasted, or else. the stamps of the lowerstrip fall about the machine indiscriminately, often getting mixed up with the glue or glue roll, and this double feedingalso frequently prevents proper gluing of the upper stamps, and failure to stamp the packages. Other objections and difliculties are well known to persons skilled in this art;

entirely eliminate the possibility of applying glue to the stamp carriers, by suitable relative formation and arrangement of the carriers and glueapplying instrumentality.

Another object is to provide for top replenishment of the strip magazine, and to otherwise improve the initial feed mech anism and its cooperation with other features of the machine.

Another object is to provide new and improved transfer mechanism for carrying the strips fromthe initial feed mechanism to the point of application to'the carrying .heads.

These and other objects, advantages, and characteristics of the invention are sufficientlyfurther explained hereafter, in connection with a detail description of the accompanying drawings, which illustrate one exemplifying embodiment of the invention. After considering this, it will be evident that many variations of structure may 'be made within the principles of the invention, also that certain features are of value apart from others, as well as in combination as shown;

and we contemplate the employment of any structures which are within the scope of the appended claims.

The machine is built upon and about a suitable frame, sufficient parts of which are shown in the drawings, including a main plate or table 1, which is supported on suitable legs or standards (not shown), and elevated longitudinal side members sup ported by

uprights

3, 4, restingon the table. A carriage 5 carries the label gripping and applying mechanism. This carriage is in the general form of a cross piece 6 having longitudinal side extension 7, fitting in guide channels 8, located on frame side members 2, and the carriage is reciprocated by suitable means, sufliciently indicated by a link 9 pivotally connected to the carriage at 10. At the forward or label applying end of the machine (at the left in Fig. 2)- the table has an elevated portion 1, and a package feed-belt 11 is arranged to move in shallow groove in this table surface. The

package belt is provided] with upwardly projecting package feed members or pushing blades 12 arranged at regular intervals so as to accommodate between each of two blades a row consisting of a suitable number .of packages P, which are in the present instance cigarette packages of the well known pouch type, arranged live in each group, with the packages uprightand with their narrower sides in contact. Evidently the number of packages in each row or group may be varied withln any reasonable limits, and the label handling jmech'anisrn as hereinafter described, may be adapted to simultaneously apply labels to any reason"- able number of packages at once. Act and adjacent to labeling position the packages P are located between vertical guide plates 13. The carriage 5 carries: a plurality of label carrying and applying instrumentalities 14, adapted to receive and hold a label strip consisting of a row of unseparated labels, and these instrumentalities are monnted for a depression movement and also for a. laterally divergent or separating movement and are controlled in this movement by a cam plate 15 supported on

uprights

16 and 17, and provided with cam slots 18, forward portions of some of which are directed divergently, as at 19.20, Fig. 1 Between the rearward location of the carriage, that is its position as shown in Fig. 2, where the applying instrumentalities receive the label strip, and the forward position, that is the location of the package'ro-w P,'are located a series of cutters 21 to cut and separate the label strip into individual labels, and a gluing instrumentality including a glue roll 22Vto adhesively condition the under faces of the labels.

The package. feed belt 11 is moved intermittently, and is supplied with packages in proper arrangement at a point anterior to labeling position. l'nrea'ch rest of the con'-.

ve'yor it locates a package row for labeling. The carriage 5 is moved in properly timed relation to the feed belt. At its rearward position a label strip is supplied to the label carrying instrumentalities; the carriage is then moved forward, the label strip is cut, the labels are gummed, the carrying instrumentalities are separated by the action of the cam' slots to position the individual labels in centered relation ,to the individual packages; the labels are brought over the packages, and the carrying instiain'ientalities are depressed while the packages are at rest; the labels are applied and released; the applying instrumentalities areretrac'ted, and the carriage returns to' rearward position while the labeled packages are moved on for further operations, such as turning down the projecting label ends, and the operations are repeated indefinitely. As so far described, the machine and its modeof operation are substantially as in the previously:

mentioned patent and pending application to which reference should be made for an understanding of suitable or representative torms of driving connections". and other parts of the, mechanism not particularly shown or; described herein.

The carriage 5 is providedwith parallel transverse round rods 25', Figs. 5' and 7, supported by the carriage side members 7 Each label carrier 14' includes a block 26 mounted toslide'on these rods, and a vertically movable head 27 guided by a pin 28 secured in an extension on block 26. A label receiving plate 29 is supported below the head 2'? byside pieces 30; A' sleeve 31 is fixed in an aperture in the block 26and has a portion 32 located in one of the cam slots lS so that in the lon itudinal movement of the carriage the entire applying unitis direeled properly and the outer. ones are moved laterally as theyapproa'ch the forward end of carriage travel by the angular portions 19 and 20 of the outward cam slots, lheceutral cam slot being straight, since in the present package arrangement the central applying instrumentality may be at all to rin vin position.

b L t: a

'conimodate portions of sleeves at between is screw-threaded and screwed provided a shifting'collar consisting spe-' cifically of disks 35 engaging exterior screw threads on the sleeve,- and lock nuts 36, also engaging the screw threads, so that the disks may be adjusted and locked, not only to form an annular shifting-groove 37 of proper vertical width, but to properly adjust the position of this groove vertically in relation to shifting and holding elements which cooperate with the shifting collar, as presently described. The heads 27 are nor mally supported in their uppermost position, in contact with blocks 26, by springs 38 compressed between the lower nuts 36' and wash?- ers 39 restin'g on the upper ends of sleeves 31. The lower portion of the rod 33 is also bored out to form a tubular portion 40, .in-- the lower end of which is mounted a vertically movable plunger 41' having a clevised end pivo-tally connected: to a lever 42 fulcruinecl on a pin 43 mounted in the side pieces 30. The outward end of this lever is provided with a pinata engaging a slot 45 in one arm of a gripper lever 46 mountedona pin 4-7 located in forward extensions of the side plates 30. The gripper lever has a suitably curved or hook-shaped gripper 48' an tral portion of the bar 33 and this rod is operatively integral with a portion 50 of larger diameter sli'dably mounted in the sleeve 34. A spring 51 compressed between plunger 41' and a shoulder at t'heupper end of sleeve 40, normally urges the gripper 48-- A shifting collar 52. 'havingan annular shifting groove 53 has a screw-threaded engagement withthe upper end of rod. 50 and is secured in adjusted:

' position by afllock-nut 54.

the shifting disks and the forward cor hem of the fingers being rounded or beveled as at 59 to facilitate the entry of these sleeve portions between the fingers. As the carriage nears its rearinost position the heads 27 are held in normal, elevated position by the springs 38, and the shifting collars are then brought into engagement with ,the holding fingers 55, the disks 35 overly ing the margins of these fingers, and during the further slight rearwardinovement of the carriage, and while the carriage is station-' ary at label receiving position, by the described means, the heads 27 and the label receiving plates 29 are held positively in elevated position to receive the label 'st'rip.

g longitu At the same time the shifting grooves 53 of rods 50 are brought into cooperation in a similar way with shifting fingers 60 formed on a plate 61, the fingers defining shifting shots 62 and having rounded or beveled corners 63, substantially as and for the same purpose as similar parts of the head retaining structure just described. The plate 61 is secured to a vertically movable member 65 having rearwardly extending arms 66 secured to the upper ends of rods 67, suitably guided for vertical reciprocation in upright 16. Y The lower ends of these rods are connected to a cross piece 68 which has a cam roller 69 engaging a camgroove 70 in a cir cular cam body '41 carried by a shaft 72. The cam groove is contoured so that as the carriage approaches rearmost position the plate 61 is elevated,-and the shifting collars 52 are engaged with the shifting fingers 60, the cross bar 68 with its rods 67 is then moved down and plate 61 is depressed and the grippers are all simultaneously retracted, so that when the carriage comes to rest in the position shown in Fig. 5 the grippers are in label receiving position.

Near the forward end of the frame, as best shown in Fig. 2, is an applier head operating. plate 75 having fingers 76 defining shifting slots 77 and corresponding substantially to the plate 56, previously described,

7 the plate 75, however, being mounted for shifting fingers 88. corresponding to the vertical reciprocation on a pair of sleeves 78, the lower ends of which are connected to a cross piece 79 having a cam roller 80 en gaging a cam groove in a cam body 81 on shaft 72. Thecam groove acting on roller 80 is contoured sothatas the carriage approaches forward position the plate 75. is elevated and fingers 77 are engaged with the shifting collars of the label carriers and thereafter at about the time that the carriage is stationary in forward position the sleeve 7 8 and plate 75 are depressed and the carrier heads 27, and connected parts are depressed and the individual labels carried by plates 29 are pressed upon the upper ends of the packages P in the position shown in Fig. 8, in which L is one of the individual labels or revenue stampsQ Approximately above plate 75 is a shifter plate 82 with plate61 previously described. Plate 82 is carried by rods 84 arranged to reclprocate win the sleeves 78 and the lower ends of these rod are connected to a cross piece 85 provided with a cam roller 86 engaging the periphery of a cam 87 on shaft 72. The cam is contoured so that as the shiftmg collars 52 approach forward position they are prop- V The cam then causes the cam plate 82 to be depressed in unison with the plate 75, and then while the plate 75 is still depressed the shifting plate 82 is raised, thus elevating all grippers resume their normal position at or about the time that the shifting collars 52 are freed from their forward operating plate. The shifting slots in plates and 82 are, of course, spaced apart to agree with the separated positions of the carrier heads and the two sets of shifting collars, as clearly shown in Fig. 1.

in the patented machine, and also in that described in the aboveunentioned application, the label carriers at label receiving position are depressed to receive a labelstrip from a magazine containing a stack of strips: and vadous difficulties, including sticking together of two or more strips, delay or annoyance in replenishing the magazine, and others understood by persons skilled in the art, result from this magazine location and method of feeding strips to the carriers. To avoid these difficulties, and to generally improve the construction and operation of the machine,'in the present in vention the label or stamp strips S are preferably arranged in a stack, in a container or magazine 90, located considerably away from the label carriers,(l ig. 3) and labels The lever is oscillated by an eccentric strap and link 99, and eccentric 100 on a shaft .101, driven by

gears

102 and 103 from a shaft 101, which is in turn driven from shaft 72 by sprockets and a chain 105. Thus the magazine. is reciprocated in properlytim ed relation, during each cycle of the machine. The base plate 91 is only long enough to support the rearward portion of the strip stack, the forward bottom portion 107 of the magazine being open. A suction roll 108 on a shaft 109 mounted in fixed bearings 110 engages the bottom strip, and by suction acting through the roll aperture 111 at about the moment the magazine starts forward in the feeding action, the forward end of the strip adheres to the roll, which is rotated by a pinion 112 and rack 113 connected to move with the magazine. The suction mechanism and control maybe as usual in feed apparatus of this class. The deflected strip end runs under a wedge or 1,47e,cse

guide 114 carried by an arm 115 secured to a fixed support 116; the .suction is broken to free the strip from the suction roll,'and shortly thereafter the strip is directed to engagement with'a'feed roll 117 cooperating with a feed or strip conveyor belt 118. During th rearward. movement of the mag azine the strip is withdrawn and fed onward by the/feed roll and belt. When the bottom strip is deflected, the, forward portion of the stack is supported bylingers "119 carried by arms 12 dependingt'r'om a rock shaft 121 movably mounted in extensions 122 of side plates .2; and these fingers are retracted at the rearward stack position, by a pin or screw 123 adjustably mounted in an arm 124i connected to shaft 121, and provided with a lock nut 125, the end of this screw being arranged to engage a fixed stop in the form of apin 126.

The strip feed belt 116 runs on

pulleys

130 and 131, and pulley 180 is driven by a gear 132 on its shaft 133, engaging gear 102 of shaft 101. Feed roll 117 is desirably driven positively by'a pinion 13 1 on its shaft engaging a pinion on shaft 133. .The upper stretch of the feed belt runs overa plate 136, and passes below the label receiving plates 29 in their rearward position, Fig. The label-strips are held with su'ficient positiveness upon the belt surface by a guide wire 13? which lies close to the belt surface, and passes below the plates 29. One end of the wire is connected to an arm 138depend ing from support l16, previously mentioned, and the other end is connected to an adjustable pin 139, screw-threaded and passing through a bracket-arm 1 10, and provided with nuts 1 11, so that the tension of the guide-wire may be regulated. Rolls 1 12 cooperate with the guide wire and belt. These are of suitable number, so that the advanccated holes in plate 136, and actuated by a bar 18. earned by aims 1&9 extending from a rock-shaft 150, mounted in brackets 151 and provided with an upright arm in which a tappet 153 is adpistably screwed,

and secured by a lock nut 154:. The individual pins 1 14, or-bar 1 l8,may be retracted by one or more springs 156. The forward end of cari' ge, so that as the carriage completes its rearward movement the rock-shaft is oscillated and pins 1&7 are-lifted, bringing the tappet 153 is engaged by apartof the strip margin into close contact with forward portions of thecarrying plates 29, and in proper position for engagement-by grippers 'ters without the complication of a train of speed multiplying gearing, although, of course, such a gear. drive interconnected with some otherpart of the machine may be provided, instead of the independent motor. The cutter edges are in line with spaces; 163 between the carrier heads 27. As the heads in their converged position, as shown in Fig. 6, carry the label strip past the cutters, the strip is divided into independent-labels L. Before the heads commence to move apart the labels are carried over and in contact with'the glue roll 22, which is mounted on a shaft 165- supported in bearings 1.66. on the glue tank 167; The roll shaft 165 has a driving gear 210 engaging a ge'ar 211 ona shaft 212 and gear 211 engages a gear 213 on a shaft 214,-, which also has a spiral. gear. 215, engaging a spiral gear 216 on shaft 72, for driving the glue roll. Below the glue roll is a dipper roll 168 which supplies glue to the glue roll.

The label carrying. faces of the plates 29 are provided with narrow ribs 170. alternating with channels, and the roll surface is formed with a plurality of narrow ribs 172, alternating with channels, the ribs of plates 29 and the roll being interspacech-or'in other words, arranged. so that ribs on theone are opposite channels on the other, as suiiiciently shown in Fig. 6. The glue roll is also'provided with deeper and wider channels, 174: to permit the grippers 4:6 to pass without conflict with the glue roll and without touching any glued surface. When a label is in proper position on any of the carrier plates 29 it is supported by the ribs 170 and its lower surface is brought properly in contact with the glue roll ribs172 and narrow parallel stripes of glue are applied to the label surface." These are sufficient to cause the label or stamp to properly adhereto the package, and in fact, in the application of the stamps to the packages and subsequent pressing of the stamps in position on the packages, these glue stripes spread more or less and provide an ample adhesive engagement of the stamp with the package, If, however, for any reason a label is absent from the carrying plate 29 during advance movement of the carriage, there is. no possibility. of contact between

ribs

170 and 172 and, therefore, it is impossible for any glue to be applied to the carrier surface, Similarly, in return movement of the carriers it is not necessary to elevate them to avoid the glue roll, or to depress the glue roll, or in fact, to make any special provision to avoid the contact of the carrier surface with any glued surfaces, since the carrier ribs always pass opposite channels of the glue roll or substantially between theiroll ribs. The carrier ribs 170 are located sufliciently close together so that the stamps are not appreciably bent by contact with the glue roll ribs; also the area of the glue stripes is so small that there is no appreciable tendency to pull the labels away from the carrying faces or from the grippers.

It is desirable to provide means to regulate the amount of glue on the crests of ribs 17 2,

For this purpose a scraper plate 176 is adjustably mounted on a wall of the glue tank by means ofslots 177 and screws 178, and

this plate has an edge conformed substantially to'the conformation of the roll surface; that is it has teeth 179 fitting closely the sides of the roll ribs 172, and at the bases of these teeth the plate is slotted out slightly asat 180, providing narrow grooves of substantially rectangular outline, or in other words, spaces which determine the amount of glue remaining on the crests of the ribs for application to the labels. Desirably the sides of the ribs 172 are slightly beveled and the sides of the scraper teeth are similarly formed so that the scraper head fits closely against the sides of the ribs and removes practically all of the glue therefrom. De sirably strippers in the form of pins or blades 182 carried by a plate 183, are provided, fit-- ing between certain of the roll ribs 172, to prevent labels running into the glue trough if for any reason they are released at this point. The dipper roll 168 is carried by a shaft 185 which has bearings in eccentric blocks 186, and these are adjustable by means of slotted sectors 187 and screws 188, so that by moving the blocks angularly the axis of shaft 185 may be moved toward and from the glue roll axis to adjust the contact between the glue roll and the dipper roll. Desirably, also, a scraper 188 is provided to regulate the amount of glue carried by the dipper roll, and'this is mounted adjustably on a wall of the glue tank by means of screws 189 passing through slots 190 in the scraper.

After gluing, the labels are separated to bring them in properly centered relation to the packages, by the diverging movement of the carrier heads, as sufliciently described above. As the carrier heads approach label-- ing position the advancing ends of the stamps encountera stop blade or plate 192, mounted on guide plate 13, this stop plate being provided with apertures 193 to accommodate the grippers.

Cigarette packages of the class described are frequently provided with an inner wrapping W, which is exposed at the upper open end of the outer or pouch wrapper X; and this inner wrapper has end flaps Y which sometimes tend-to spring up or pro- 7 ject, and interfere more or less with the proper movement of the stampsto applica tion position and this displacement of the flaps may even prevent the proper position- 7 ing and securing of the stamps. To insure the proper positioning of these flaps, flap depressers or holders in the form of blades 195 are mounted on a rock shaft 196 and are normally retracted, as shown in Fig, 2, by a spring 197 connected to a pin 198 on the shaft. The depresser blades are properly positioned and spaced apart to avoid conflict v with the advancing stamps and carrier heads; that is to say, they are arranged opposite the spaces between the now divergently separated heads, and in this position the depresser blades lie over portions of the flaps Y to one side of the stamp location, as sufiiciently indicated in Fig. 8. The rock shaft 196 has an arm 200 carryin a cam v roller 201 in the path of a cam plate 202 secured to one of the carriage side members 7 turns the presser blades 195 to elevated position, so that the packages may freely move away and a new set of packages come into position.
