21 Claims. (Cl. 216-54) This invention relates to labeling machines and more particularly to mechanisms for applying labels to containers in succession with substantially complete adhesion of an entire label to the container to which it is applied.

It is conventional in labeling machines to transfer labels individually from a label magazine through intermediate positions for application to a container at a label applying station. In such machines, an individual label is withdrawn from the magazine generally by suction means. On its withdrawal by such suction means, it is seized by pick-off and transfer mechanism and carried to the label applying station, being gummed in transit. The pick-01f and transfer mechanism grips the label along a narrow border portion or strip and carries the gripped label past an adhesive applying roller, and then to the label. applying station whereat the label is applied to a container arriving simultaneously at the station. The narrow strip of label engaged by gripping jaws of the pickoff and transfer mechanism, however, is covered by them and does not receive adhesive as the label is swept past the adhesive applying roller. In consequence, this narrow strip will not adhere to the container, and may cause difficulty in later packaging or under other circumstances.

It is important that practically all portions of the labels be adhered firmly to the container to eliminate packaging difficulties, particularly when the labeled containers are transferred to high speed packaging machines. One solution for this problem is presented in Herman D. Manas, US. Patent 2,873,040, dated February 10, 1959. The solution therein provided is the application by special mechanism of a stripe of glue to each container in ad- Vance of its arrival at the label-applying station. The glue stripe is applied to a position on the container corresponding to that portion on which the non-adhesive bearing narrow strip or border of the otherwise gummed label will lie when the label is applied to the container. Thus, when the label is pressed against the container, there will be adhesive present in all corresponding areas either of the label or of the container to insure complete adhesion of the entire label to the container.

Principal objects and features of the present invention are the provision of different mechanism than that provided in the said patent for effecting adhesion of substantia-lly the entire area of each label to the container to which it, is applied, and very rapid labeling of containers.

In practising the present invention, each label to be applied to a container is removed from a label magazine by temporary adhesion to a previously-gummed surface of a novel label remover means which moves relative to the delivery or outlet end of the label magazine. The said adhesive-bearing surface is pressed firm-1y against the leading label at the outlet or delivery end of the label magazine while counter pressure is maintained on the pile of labels in the magazine as by a counter weight. The firm pressure of the adhesive-bearing surface against the surface of the leading label causes transference of adhesive from one to the other and also adhesion of a temporary nature between the two. Immediately after such adhesion has been effected, the leading label is released from the magazine as the label remover means is moved away from said magazine. This causes the leading label now adhered temporarily to said adhesive-bearing surface to be readily withdrawn past the retaining fingers (then in a release position) of the label magazine and clear of said magazine.

The particularly removed label now temporarily adhered to the surface of the label remover means is carried away from the label magazine and brought to a seizure point or position where it may be stripped from said means by a pick-ofi. and transfer mechanism.

The pick-off and transfer mechanism is in the form of a rotary turret. It includes a movable jaw having teeth of small dimensions that may move through appropriately provided slots or notches in the surface of the label remover means at said pick-off seizure point to clamp small ungummed areas of the label adhered to said surface against a fixed jaw on the turret. This serves to clamp the label to turret parts and on continued motion of the turret to strip the label from said surface of said label remover means. The portions of the stripped label which have been in contact with the latter surface retain adhesive transferred thereto by the said surface. Thus, the stripped label is now partially gummed. However, the small areas of the label which were aligned with the said slots or notches in said surface remain ungummed. These small ungummed areas are the ones engaged by the teeth of the movable jaw when clamping is effected by the latter. These areas are negligible in size as compared to the entire area of the label.

When clamping of a label by the turret parts has been effected at the seizure point, the clamped label is moved by the rotating turret from the seizure point to a partial label applying station. In such movement the clamped label is first carried past a main adhesive applying roller. In the sweep of the label past the main adhesive applying roller, the latter applies gum or adhesive'to previously ungummed surfaces of the label and also to some portions of the area already containing adhesive by previous transference from the gummed surface of the label remover means. The ungummed areas covered by the teeth of the movable jaws, however, remain ungummed. Thus, when the label arrives at the partial label-applying station, adhesive has been spread on the entire surface of the label except for the small and negligible ungummed areas covered by the teeth of the movable jaws.

The label is unclamped from the turret at said station by opening movement of its movable jaw, and wide band portions of its gummed or adhesive bearing surfaces are pressed against and adhered to the surface of the con tainer arriving at said station by cooperating presser mechanism within the turret. Then the container bearing the label partially adhered thereon is moved beyond the initial partial label applying station to a further position at which position the label is completely pressed against the container by appropriate mechanism.

As adhesive has been applied to the major areas of the label as described and only the minor small areas covered by the teeth of the movable jaws have remained ungummed, substantially complete adhesion of the entire label to the container occurs. As a matter of fact, the pressure applied between the label and the container at said further position in completing the adhesion betweeri the two also may cause some oozing spread of adhesive into the small ungummed areas so that even these thereby become adhered to the container.

Other objects and features of the invention are the provision of novel means for removing labels successively from a label magazine by adhesion, with partial gumming of. a selected area of each label as it is removed by said means in advance of seizure of the label by pick-off and transferring mechanism and gumming of the remainder of the label.

Other objects and features of the invention are the provision of means for operating the label remover means relative to the label magazine and of means for oscillatin g the latter during operation.

Additional objects and features of the invention are the provision of controlled means to exert pressure on the pile of labels in the label magazine toward the delivery end of the label magazine which is sufiicient to provide a reasonably firm abutment for the leading label at the moment the adhesive bearing surface of the label removed means arrives for engagement with and adhesion to such leading label in the magazine, thus insuring full contact between adhesive bearing surface and adhesive receiving area of the label and temporary adhesion between the two.

Other objects and features of the invention are to provide novel means for applying adhesive to the label removing means.

Other objects and features of the invention are the provision of simple mechanisms for operating the various components of the machine in a coordinated manner and to provide for high speed labeling of containers.

Referring to the drawings and first to Figures 1 to 5 and 24, the various mechanisms of the machine in assembly are arranged with reference to a table 10. These mechanisms include, generally, conveyor means 11 for containers, means 12 for spacing the containers on the conveyor means, means 13 (Figure 24) for clamping the containers on a conveyor means in spaced condition, a label magazine 14, label remover means 15 for withdrawing labels individually from the label magazine by adhesion, pick-off and transfer means 16 for seizing labels adhered to the label remover means and for transferring them to a label-applying station I, means 17 for applying adhesive to non-adhesive bearing portions of the label during such transfer, means 18 (Figure 5) for par tially applying a portion of the adhesive-bearing labels successively to containers arriving at the label-applying station I and means 19 at a completion station II beyond the label-applying station for completing the adhesion of the labels partially applied at station I to the respective containers.

All of these means are appropriately positioned relative to each other and with reference to the surface of the table 10. Driven portions of these means are operated by appropriate driving means 20 (Figures 22 and 23), preferably located below the surface of the table 10 and enclosed, for example, by a protective apron or casing 21.

The conveyor means 11 is conventional and comprises an endless band 22 including horizontal upper flight. The upper horizontal flight of the band 22 provides a substantially horizontal surface on which the containers C to be labeled are moved. The band 22 is driven preferably in a continuous manner by any conventional driving mechanism (not shown) so that the upper flight of conveyor band 22 moves continuously, for example, in the direction of the arrows shown in Fig. l.

A pair of

guide rails

23 and 24 as positioned at opposite sides of the upper flight of the conveyor band 22 extend parallelly with its direction .ofmovement. One

of the guide rails 23 is adjustable transversely relative to the other rail 24 in order to accommodate differently dimensioned containers C to which it may be desired to apply labels. The selected containers C to be labelled are placed either manually or mechanically on the upper flight of the conveyor band 22 at, for example, its extreme left with their bottoms resting on the band. Friction causes these containers C to move forwardly with the conveyor band 22 to the spacer means 12, for example, of the conventional worm type.

This spacer mechanism comprises, for example, a worm groove 24 on a shaft 25. The shaft 25 is driven by any suitable mechanical means (not shown). On rotation of spacer shaft 25, its worm groove 24 engages the container C arriving at its starting end and in its rotation acts to separate successive containers C uniform distances apart on the conveyor band as they emerge successively from the groove 24.

The uniformly spaced-apart condition of the containers C as they leave groove 24 is maintained by the positive clamping means 13. This clamping means 13 in the embodiment shown (Figures 2 and 3) is provided by the vertically adjustable endless band 26 which is trained around the guide pulleys 26a, 26b and 260. These pulleys are carried on a horizontal vertically movable frame part (not shown). Vertical adjustment of said frame and band 26 is effected in conventional manner to accommodate containers of different heights.

At least the outer surface of clamping band 26 is of cushion-like material such as rubber or the like so that it will press resiliently against the upper ends of the containers C as they pass under the lower flight of said band 26 just as they leave the worm groove 24 of the spacer mechanism 12. The pressure of the lower flight of band 26 on the containers C provides a resilient clamping action which maintains the containers C in a clamped regularly-spaced condition on conveyor band 22 until the containers C move out from under the lower flight of said band 26 at a later stage as will be described. The band 26 is freely rotatable around its

pulleys

26a, 26b and 26c and moves at the same speed as conveyor band 22 when containers C are clamped between the two.

While the containers C are maintained in this clamped condition, each, as it moves past an initial partial labelapplying station I, has a label L partially applied thereto as seen in Figures 13 and 24. After such partial application of a label L to each succeeding container C at station I, the containers are moved beyond said station I to a further label application completion station II which lies beyond the label-applying station I and at said station II the partially-adhered labels L are completely pressed against and adhered to their respective containers.

The labels L which are intended to be partially adhered to the containers at the label-applying station I are transferred individually and successively to said station from a pile in a horizontally oscillatable label magazine 14 (Figures 1, 2 and 3). This label magazine 14 has sets of retaining

fingers

27 and 28 at opposite sides of its outlet end past which each label must be drawn for removal from the pile in the magazine. The fingers 27 at the innermost side of the magazine may be moved to release or clearing positions temporarily, as will be described (see Figures 14 and 15). A ram or pusher 29 serves to urge the labels in the pile against the

fingers

27 and 28. Pressure is maintained on the ram as by a cord 39 secured at one end to the pusher guide rod 31 and after passing over a pulley 32, at its other end to a counterweight 3'3. The pressure of the ram 29 on the pile P of labels in the magazine acts to provide an abutment for the label pile for purposes presently to be described. Means are provided, as will be described, for momentary release movements of the fingers 27 which, when it occurs, permits the leading label in the pile to be withdrawn from the magazine. The horizontal table 34 which carries the I label magazine 14 is oscillated in synchronism with movements of other parts as will be described.

The successive leading labels L of the pile within the magazine 14 are withdrawn individually from said magazine by adhesion to an adhesive-bearing surface 35 on a head 36 of the movable label-remover means 15. In the embodiment shown, two diametrically-disposed heads 36 are provided on the label remover means 15. Each of the heads 36 performs a double function. Its surface 35 engages a leading label in the pile on the magazine and withdraws it. Also each surface 35 applies adhesive by transference to a partial area Lg (Figure 17) of the surface of each label L that it withdraws from the pile in the label magazine. The temporary adherence of a label L to each surface 35 acts, when its head 36 is moved away from the label magazine, to withdraw an adhered label from said magazine. The movement of such surfaces 35 of the label remover means 15 away from the label magazine 14 carries the respective labels L adhered to them successively to a position for seizure therefrom by the rotary label pick-off and transfer mechanism 16.

Label remover means In the embodiment shown, the label remover means 15 includes two vertically supported, diametrically located heads 36 (Figures 1, 2, 3, 4 and 17). Each head 36 is secured to a vertical shaft 37 which is rotatably carried in a block 38. Block 38 is secured to a driven vertical shaft 39. A removable member 40 which includes an adhesive-bearing surface 35 is secured to each head 36. Spaced-apart notches or recesses 41 (Figure 2) are provided along one longitudinal edge of each member 40 and its surface 35 for purposes to be presently described. Each surface 35 is intended to have adhesive spread thereon cyclically as the heads 36 are moved in a circular orbit during rotation of block 38. Each time adhesive has been so spread on a surface 35, the latter is moved thereafter during the orbital movement of the head 36 into pressing surface contact with a small area Lg of the leading label then in the magazine M. Oscillation of the head supporting shafts 37 occurs during periods of the orbital motion to position the surfaces 35 properly both to receive adhesive and for face to face engagement with the label surface or to prevent such engagement. The engagement causes temporary adherence of a leading label in the magazine to said surface 35 and also a transference of adhesive therefrom to the contacted area Lg of the label from the surface 35.

The rotatable shafts 37 which carry the heads 36 extend through the block 38. Cranks 42 are secured to the shafts 37 below block 38 and are equipped with cam followers 43 which track a cam surface 44 in a horizontally disposed cam plate 45 (Figures 48 incl.) mounted on the table 19. Biasing springs 46 are secured respectively at 47 to the heads 36 and to pins 48 attached to the block 38. These springs function to bias the cam followers 43 toward cam surface 44 so that, during orbital movement of the heads 36 about the axis of the block-carrying shaft 39, oscillatory swiveling motion'may be imparted to the respective heads 36 on the respective axes of their support shafts 37. The effect of this swiveling oscillation of the heads is to effect lateral motions of the surfaces 35 during their orbital travel so that said surfaces may have adhesive applied effectively thereto by the adhesive-applying mechanism 17 as will be dedescribed in one position of their orbital travels and also in another position be swung for effecting a firm pressing engagement of such an adhesive bearing surface with the leading label in the magazine to cause temporary ad hesion of such label thereto, and immediately thereafter be swung or oscillated reversely to initiate withdrawal of the adhered label from the label magazine.

A crank 49 is positioned on the under side of cam plate 45 and pivoted at 49a. This crank has an edge surface 50 (Figure 19) which is biased by action of a 7 biasing spring 51 toward a cam path altering position for the cam followers 43. The crank 49 is provided at another portion with a trip nose 52 which is normally engaged by a pivoted latch 53 (Figure 1). This latch 53 in turn is provided on a pivoted bell crank 54. The crank 54 is biased by a spring 55 (Figure to normally maintain the latch 53 in engagement with nose 52. A link 56 (Figure l) connects the crank 54 with an arm 57 of another pivoted bell crank 58 whose other arm 59 as a feeler normally is positioned by the biasing action of spring 55 to lie in the path of travel of successive containers C on conveyor band 22 after they have left the worm groove 24 of spacer 12. This engagement displaces feeler arm 59 and causes latch 53 to free trip nose 52, thus freeing crank 49 and permitting the cam follower 43 of a head 36 to shift crank 49 against the action of spring 55 and to ride on the portion of cam surface 44 which is otherwise masked by the surface 50 of crank 49 in the described untripped condition of the latter. The said portion of cam surface 44 is so shaped that it permits the head 36 of the particular cam follower 43 to swivel in response to the action of springs 46 and of said portion of said cam surface. Thus, surface 35 of the swivelled head 36 will lie in a position to engage the leading label in the magazine. If no container, however, should appear on the conveyor to effect the described tripping of feeler arm 59, the locked condition of crank 49 will prevent the cam follower 43 from following the said portion of cam surface 44 because surface 50 of crank 49 will mask surface 44 and the particular head 36 will not at this time be swivelled to bring its surface 35 into a position to contact with the leading label in the label magazine, thus providing a safety device and waste preventer by preventing withdrawal of a label from the magazine when there will be no container present at the label-applying station I to which it can be applied.

The movable label magazine fingers 27 on the inner side wall of label magazine 14 (Figure 16) are disposed parallelly in slots 60 and are secured to a pivoted yoke 61 carried by a spindle or shaft 62 so that the outermost ends of fingers 27 may be moved inwardly of the magazine side wall to engage the leading label of the pile in said magazine, or swing outwardly to a label-releasing position. Levers 63 are secured to the yoke at 64 and respectively to biasing springs 65 which normally bias the yoke 61 and fingers 27 carried thereby into labelengaging position. The adjustable stops 66 limit the biasing action of said springs. A trip lever 67 is secured to the spindle 62. This trip lever 67 has its outermost end positioned to be engaged by a nose 68 on each crank 42 in one of the positions of the latter as effected by operation of its cam follower 43 as controlled by the position of the edge surface 50 of the crank 49. When such engagement occurs, the trip lever 67 rotates spindle 62, yoke 61, and fingers 27 to a release position outwardly of the magazine, to permit withdrawal of that leading label in the magazine 14, which has become adhered to the surface 35 of the particular associated head 36. Immediately upon completion of label release, the trip lever 67 is released by nose 68 permitting fingers 27 to return to label-gripping position under action of springs 65.

The label magazine table 34 itself is preferably provided with horizontal oscillatory movement. To this end, it is supported as by a vertical shaft 69 which also has a crank 70 secured thereto. This crank is coupled to the link 70a and via this link is coupled to an eccentric 71 on a driven rotary shaft '72 (Figure 16) so that driven rotary motion of the latter imparts oscillatory horizontal motion to the magazine 14 about shaft 69 as a center. This oscillation, as will be described, is synchronized with movements of other parts to facilitate proximate tangency between an adhesive-bearing surface 35 of each head 36 as the said surface arrives opposite the leading label in the magazine so as to adhere to and removesuch label therefrom.

In the embodiment shown, two heads 36 are carried by rotary block 38 and are located at diametrically opposite points. If desired, one head 36 only, or more than two heads 36 symmetrically disposed on block 38 may be utilized. Similarly, the heads 36 may receive required motion in relationship to the magazine 14 and to the roller 75 by other mechanisms than those specifically described. Such motion could, in fact, be reciprocal rather than rotary in nature. The embodiment presently described, however, is deemed preferable.

The various components of the label magazine 14 may be adjusted in conventional ways so that differently dimensioned labels may be introduced into the magazine 14 for application to the same or different types of containers. In addition, the elevation of said magazine 14 may be adjusted to position labels for application therefrom to containers at any selected container level. This latter adjustment may be accomplished, for example as illustrated in Figure 3, by the use of elevator screws 73 and associated frame parts 74 for raising and lowering the label magazine table 34.

Adhesive applying means It is necessary once during each orbital trip of each head 36 to apply adhesive to its surface 35 in advance of the face to face engagement of such adhesive-bearing surface 35 and the surface Lg of a leading label in the label magazine. In the embodiment shown, adhesive is applied to each surface 35 in the required manner by causing these surfaces successively to sweep past and in engagement with an auxiliary gummed or adhesive application roller 75. This roller 75 is supported on a vertically-disposed axle or shaft 76 for free rotation as in a bearing 77. This bearing is so positioned that the periphery of auxiliary application roller 75 makes rolling contact with the surface of a main adhesive-dispensing roller 78, so that adhesive spread upon the surface of main roller 78 by delivery from a dispensing nozzle 79 and spread to substantial uniformity of depth thereon by an adjustable doctor blade 80, will be transferred to the surface of auxiliary applicator roller 75.

The main adhesive dispensing or gumrning roller 78 as seen in Figures 1 and 2 is supported vertically on a driven shaft 81. The roller 79 rotates with driven shaft 31, and the adhesive dispensed by the nozzle 79 near the upper end of roller 78 moves downwardly onto the outer surface of said roller. It is spread uniformly on this surface by the doctor blade 80. The later is biased as by springs 82 whose pressure is adjastable as by bolts 83 to regulate the thickness of the adhesive layer spread onto the surface of said roller 78. The adhesive is conveniently pumped to nozzle 79 by appropriate means from a reservoir (not shown). A sump 84 underlies main roller 78 and serves to collect adhesive dripping therefrom for recirculation.

Only main roller 78 is positively driven by driven rotation of its shaft 81. Adhesive is transferred from the surface of main roller 78 to the surface of auxiliary roller 75 by contact which also serves to turn the latter roller.

During orbital movement of the heads 36 on rotat'on of block 38, the circular and non-circular portions of cam surface 44 control the extent of axial swing or swivel of the head shafts 37 of respective heads 36 so that their adhesive-receiving surfaces 35 are swung on the axes of their shafts during their normal circular orbital travel first to provide tangent contact between each surface 35 and the adhesive-bearing surface of auxiliary roller 75 as each surface 35 sweeps past such roller to effect a transfer of adhesive thereto. Thereafter in the continuous orbital movement of the heads 36, the surface 35 bearing transferred adhesive is carried to a location approximately beyond the transfer position without substantial shift in relative angular disposition to the orbital path for ad hesive engagement with a leading label in the label magazine 14.

If a container C on conveyor 22, however, has operated feeler lever 59 so as to release trip nose 52 of the crank 49 in this period of orbital motion of the particular head 36, the crank 49 and its surface wi.l yield as the particular cam follower 43 arrives for engagement therewith so that an unchanged portion of cam surface 44 remains engaged by such cam follower 43 and relative swiveling disposition of adhesive bearing surface 35 remains unchanged. In consequence, as seen in Figures 6 and 7, the adhesive bearing surface 35 approaches the outer face of the leading label L in the magazine 14 which at this time is swinging in opposite direction in a circular path substantially tangent to the orbital path of said surface 35. When contact between adhesive-bearing surface 35 and the outer face of the leading label occurs as in the POSl.'iOI1 depicted in Figure 7, pressure is exerted by adhesive-bearing surface 35 against said outer face. This causes temporary adhesion of the said label L to said surface and also transfer of adhesive from surface 35 to the label face in a pattern Lg (Figure 17) conforming substantially to the contour of the surface 35.

Immediately beyond the engagement position as depicted in Figure 7, continued rotation of head-earrying block 38 causes cam follower 43 which controls the particular head 36 to whose surface 35 the leading label L is adhered to move onto a changed portion of cam surface 44, which then acts to swing head 36 and its surface 35 in a direction outward of and away from the magazine 14. This camming action also at this time functions to position the nose 68 (Figure 14 and 15) of crank 42 so that it simultaneously engages trip lever 67 and thereby causes a momentary release movement of gripping fingers 27 so that the inner edge of said leading label L is freed and may be swung outwardly away from said label mgazine by said head 36 as is depicted in Figure 8. Further rotation of block 38 causes the particular head 36 with a leading label L adhered to its surface 35 to draw the said label outwardly of said magazine, as is seen in Fig. 9. The gripping fingers 27 in the interim also have been restored by action of their biasing springs 65 to retaining position in advance of the next succeeding label in said magazine 14. The oppositely directed oscillating movement of label magazine 14 effected by the action of crtnk 71 (Figure 16) during this particular period as denoted by the arrows in Figures 69 incl. facilitates initial contact, adhesion, separation and withdrawal of each said leading label adhered to a surface 35 from the pile in the magazine. Oscillation of the magazine can, if desired, however, be eliminated.

Upon compfetion of withdrawal of a leading label from the magazine, the further continued rotation of said block 38 causes the head 36 bearing such a withdrawn label to bring the latter to a pick-off and transfer position at which appropriate pick-off and transfer mechanism 16 serves to strip the label arriving at such position from the surface 35 of head 36 bearing it for transfer to the label-applying station I. When two heads 36 are utilized as in the embodiment shown, two labels normally are withdrawn from the label magazine for each revolution of the block 38, the number withdrawn per revolution of the block being usually consonant with the number of heads 36 carried by said block, unless there is an intended failure of withdrawal caused-by non-appearance of a container as has been described.

Pick-ofi and transfer mechanism (F igures 2-5 incl.)

The pick-off and transfer means 16 in the embodiment shown is of a rotary turret type and may be similar to that of Manas Patent 2,873,040, dated February 10, 1959, modified, however, as required for the particular purposes of this invention. As provided herein, this pick-off and transfer mechanism includes a pair of spaced-

apart discs

85 and 86 secured for rotation with a driven verticallydisposed shaft 87 extending upwardly of table and driven as will be hereinafter described.

The peripheries of these

discs

85 and 86 are provided with equi-spaced, aligned recesses or notches 88 and 89.

These notches respectively have the radially-directed

portions

90 and 91. Fixed jaw members 92 span the space between discs and 86 and are secured to the respective radially directed

portions

90 and 91. These fixed jaws 92 and the

discs

85 and 86 provide a rotary turret frame 93 which is rotated by driven shaft 87.

Movable gripping means 94 are provided on the turret frame 93. These means 94 include spaced-apart gripping fingers or teeth 95 (Figures 3, 20 and 21) which are pivotally supported on a pivoted bar 96 spanning the

discs

85 and 86. These teeth or fingers 95 are movable toward and away from the fixed jaws 92. The number of teeth 95 and their spacing corresponds to the number and spacing of notches 41 (Figure 2) in the pad 40 and surface-35 of the head 36. The movable jaw teeth 95 as seen in Fig. 3 are mounted on bar 96 to whose rockable support shaft 97 one end of a rock lever or crank 98 is secured. A cam follower 99 secured to rock lever 98 rides on a stationary cam 100 positioned about turret shaft 87, said cam 100 being secured against rotation in any conventional way. A biasing spring 101 maintains contact between each cam follower 99 and said stationary cam 100 so that during rotation of the turret frame 93, the teeth 95 are oscillated or swivelled toward and away from the fixed jaw 92 so that said teeth 95 may alternately engage and disengage said fixed jaw 92.

The position and shape of cam 100 is such that the movable jaw teeth 95 are in open position relative to the fixed jaws 92 as they arrive at the pick-off point or position for removing individual labels L from successively arriving heads 36 as seen in Figure 10. At that instant the lead ing label L removed from magazine 14 and adhered to a surface 35 of a particular head 36 is in a position within the path of travel of a fixed jaw 92 and almost engaged by the latter. At that instant, the cam follower 99 (Figure 21) moves into a portion of cam 100 which permits the movable teeth 95 associated with the particular fixed jaw 92 to snap closed through the notches 41 in surface 35 of said head 36 against the said associated stationary jaw 92, thus clamping the portions of the label L aligned with the notches 41 between said fixed jaw 92 and the teeth 95 as seen in Figure 11. At the instant of such clamping of the label L, the linear speeds of head 36 and of the turret 93 are alike. Immediately after said clamping occurs, the particular head 36 swings on its shaft 37 as it moves out of the turret orbit and clear of. the clamped jaw and teeth because of rotation of block 38 and action of cam followers 43. As a result, the clamped label as seen in Figure 12 is stripped from the surface 35 of the said head 36 by the clamped teeth 95 and jaw 92 and they carry the clamped label along during further continued rotation of turret 93.

The gripped label L (Fig. 12) at this time has an area I Lg (Figure 17 which has been gumrned because of transfer to it of adhesive from the surface 35. This gumming does not, however, occur on those small portions Lu of the label which were aligned with notches 41 of surface 35. Hence, when the teeth 95 clamp the label to jaw 97 they engage only ungummed small areas Lu. adhesion of labels to jaw teeth 95 will occur.

The major area Lm of each succeeding label L seized by the pick-off and transfer turret 93 still require application of adhesive to it. This is effected during further rotation of turret 93 as they are carried around by it to the label-applying station I. This application of adhesive is effected by main adhesive applying roller 7-8 by movement of each gripped label L by the turret 93 past the surface of the said roller.

To assist in application of adhesive to each area Lm of successive labels, presser feet 102 (Figures 2, 5, 10, 11, 12, 20 and 21) are provided on the turret 93, one for operation in conjunction with each set of gripping teeth 95 and its associated stationary jaw 92. The presser feet 102 each respectively is secured to a pivot bar 102a which is supported rotatably in a crank 103a which is secured Thus no to a rock shaft 103 extending respectively between

discs

85 and 86. The pivot 102a is also secured to a link 104a and the latter in turn is pivoted at 104b to a link 1040. Link 1040 is pivoted on a fixed pivot pin 104d which is mounted on the lower plate 85 of the turret. A crank 105 is secured to each rock shaft 103 above upper turret disc 86 and is provided with cam follower 105a riding on a stationary cam 106 against which it is pressed as by a biasing spring 107, connected at 107a to disc 86 and connected at 107b to a crank 108 which is secured to shaft 103 below disc 86. The cam 106 is so shaped that each presser foot 102 normally lies retracted by action of spring 107 within the cylindrical envelope defined by the peripheries of

discs

85 and 86 when its associated cam follower 105a rides on high portions of cam 106 and each presser foot 102 is swivelled radially outwardly of said envelope against the action of its associated spring 107 as its cam follower 105a rides onto lower portions of said cam 106. The presser feet 102 may be covered at their outer surfaces with a resilient pad 109 of rubber or the like having desired contour.

The low portions of cam 106 are so disposed that as the turret 93 carrying a gripped label rotates from the position where a label has been picked-off from head 36 toward the main adhesive-applying roller 78, the particular presser foot 102 directly behind the gripped label is swivclled outwardly sufficiently for its surface 109 to form a back stop for the gripped label as it is swept past the adhesive-applying roller 78. Thus, the area Lm of the label is pressed against said roller 78 and coated with adhesive from said roller. Parts of area Lg of the label also are recoated by this movement past said roller 78. Thus, all areas of the label except the small areas Lu which still are covered by teeth 95 are now coated with adhesive. 103a serve as a so-called parallel linkage which acts to maintain a substantially linear in and out radial motion of pad 109 relative to the envelope defined by the

discs

85 and 86 of the turret 93 during swivelling motion of crank 1030 under action of cam follower 105a.

The gripped label L bearing adhesive in its areas Lg and Lm is then moved beyond adhesive-applying roller 7 8 by the continuously rotating turret 93 and to the labelapplying station I (Fig. 13) at which station a container C arrives at substantially the same time. Just after the leading edge of the gripped label sweeps slightly past the center of station I, the movable teeth 95 move away from the associated fixed jaw 92 to release the leading edge portion of the label L. Simultaneously presser foot 102 is moved outward under action of cam follower 105a I ing edge L to the container C thus occurs at said station I. I

The surface speed of cushion or pad 109 at this time is equal substantially to speed of conveyor 22, so that as it yields while being pressed toward the container, it effects a susbtantial wide band of adhesion between the label and the container at said station I.

As the label-bearing container C is moved by the conveyor 22 in continuous motion of the latter beyond the initial label-applying station I, it carries the partiallyadhered label therewith to the label application-completing mechanism 19 at a station II (Fig. 1).

This mechanism 19, in the embodiment shown, comprises an endless belt 110 trained about a pair of pulleys 111 and 112. The belt 110 may be entirely of or else have an outer resilient surface 113, for example, of sponge rubber. This belt 110 is positioned so that its inner flight lies to one side of conveyor 22 and moves in the same direction. One or both pulleys 111 and 112 maybe driven to provide desired surface speed to the belt 110. The inner flight of the belt 110 is backed preferably as by an appropriate adjustable guide plate 114.

The

links

104a and 104c together with crank 12 A backing bar 115 is mounted on brackets 116 which are adjustable horizontally over the top of table 10. Backing bar 115 extends in parallelism with the inner flight of belt 110, and is spaced therefrom in accord with the dimensions of the containers passing between the belt and bar.

As each partially-adhered label-bearing container C is moved beyond station I toward station II by conveyor 22, it moves between the facing flight of belt and bar 115. Resilient surface 113 of belt 110 yields and the moving belt whose speed may be somewhat in excess of the speed of conveyor 22 serves to roll the label-bearing container C on its vertical axis in counterclockwise direction the unadhered portions of the label L to be wrapped around the container and pressed into smooth adherence therewith.

If the containers are parallel faced, e.g. rectangular in section rather than cylindrical, the belt 110 at such time moving preferably at the same speed as container 22 serves to press or iron the label onto the container by action of its resilient surface 113. The adjustability of bar permits accommodation of differently-dimensioned containers merely by shifting of brackets 116.

It is understood, of course, that the containers C become unclamped from conveyor 22 in advance of their arrival between belt 110 and surface 115 by moving out from under the lower flight of clamping band 26 as seen in Fig. 2.

Other mechanism for completing adhesion of the label to the container at station II may be utilized such as that of the afore-mentioned Manas patents or other known mechanisms.

Driving means The driving means 20 which provides for rotation of required components is illustrated diagrammatically as seen in Figures 22 and 23. It includes an electric motor 117 which is coupled via a clutch 118 on its output shaft 119 to a drive gear 120. This gear 120 meshes with the gear 121 which serves to rotate the turret shaft 87 and thus to rotate turret 93. Gear 121 also meshes with a gear 122 which turns the main adhesive roller shaft 81. In addition, gear 121 meshes with another gear 123 which drives the shaft 39 of block 38 which carries the heads 36. Other appropriate gears (not shown) meshing either with gear 121 or gear 120 may be utilized to impart required driven rotation to the conveyor 22, the worm spacer shaft 25, the belt pulleys 111 or 112 and to the pump (not shown) which circulates adhesive to roller 78 via nozzle 79.

The clutch lever 124 serves to operate clutch 113 either to couple or uncouple gear 120 to or from motor shaft 119 so that asingle control manipulation will serve to initiate and halt driven movement of the entire machine and its movable parts even if power to motor 117 remains on. Other conventional means for effecting continuous drive of moving parts in appropriate synchronized relationship are possible and are contemplated.

Operation Containers C to be labelled are positioned on conveyor 22 in advance of the spacing means 12. Labels L are loaded into label magazine 14 so that the first leading label is maintained pressed against

fingers

27 and 28 by action of weight 33 and ram 29. Adhesive is fed to main adhesive-applying roller 78 via dispensing nozzle '79. The motor is then started and clutch lever 124 is manipulated to connect gear 120 to drive shaft 119. This initiates movement of conveyor 22, the rotation of Worm spacer 24, the rotation of main glue-applying roller 78, the rotation of turret 93, the rotation of block 38 and consequently of heads 36 thereon in an orbital path, oscillating movement of the label magazine 14 and movement of the belt 110.

The unlabeled containers C placed at the entrance end of the machine are advanced by the continuously moving conveyor 22 to the spacer worm groove 24 which engages and spaces the individual contains C so that they lie at uniform distances apart after leaving said groove. The upper ends of successive spaced containers directly then pass under the lower flight of clamping band 26 which thereafter maintains the containers in clamped condition on moving conveyor 22. The clamped uniformly-spaced, unlabeled containers C are then further advanced by conveyor 22 toward the initial partial label-applying station I. As each clamped container C passes the feeler arm 58 which lies in its path of travel as seen in Figure 1, it causes the latch 53 to trip and to release trip nose 52, thus freeing crank 49 so that its surface 50 will not affect the operations of that cam follower 43 which next approaches it and the movements effected by the latter will be governed only by the shape of cam surface 44. Thus, the one of the two orbitally moving heads 36 associated with the particular cam follower 43 and to whose surface 35 glue or adhesive has been applied by contact with adhesive roller 75 in advance of the freeing of crank 49, now during continued rotation of block 38 approaches the leading label L in label magazine 14. Cam surface 44 acts on said particular follower 43 as the particular head 36 so approaches said label to swing the adhesivebearing surface 35 into pressing engagement with the surface of said label as shown in Figure 7.

The label-retaining fingers 27 are then momentarily moved to release the said leading label by action of nose 69 on finger operating lever 67. As this occurs, the head 36 is swung to cause the leading label now temporarily adhered to it to withdraw said label and clear the fingers 27 which immediately thereafter return to label-retaining position in magazine 14 as nose 68 clears lever 67. The head 36 hearing the withdrawn label continues in its orbital path with continued rotation of block 38 as seen in Figure 9 carrying the withdrawn label to the pick-01f and transfer position of Figure 10.

At the time of such arrival, the turret 93 has rotated so that one of its fixed jaws 92 and associated set of gripping teeth 95 lies at a position as shown in said Figure 9, so that the fixed jaw 42 lies directly behind the leading edge of the gripped label while teeth 95 are in a position to close which they now do as seen in Figure 11 under action of stationary cam 100 on the associated cam follower 99. The teeth 95 during closing movement pass through the notches or slots 41 in head 36 and clamp the label firmly against the associated fixed jaw 92. Continued movement in orbit of head 36 and also rotation of turret 93 I move the particular head 36 out of the path of travel of the turret teeth and jaws and strip the gripped label from the surface 35 of said head as is seen in Figure 12. The gripped label is now carried by the turret 93 as seen in Figure past the main glue-applying roller 78 which by contact applies adhesive to the portion Lm of said label. The gripped adhesive bearing label is then further carried by further continued rotation of turret 93 to the initial partial label-applying station I. On arrival there the cam 100 acts on cam follower 99 of the particular gripping teeth 95 to move them to release position. Likewise the cam 106 then acts on cam follower 105a associated with the particular presser foot 102 directly behind the released label to shift its resilient surface 109 against said label and to press a wide band thereof against the surface of a container C which arrives at said station I at the same time. This effects partial adherence with a Wide band of adhesion between the label and the particular container C.

This container C now bearing the partially-adhered label thereon moves beyond said station I toward station II and'in so doing moves out from under the clamping band 26 so that the container is unclamped. As it arrives at station II, it enters the space between the fixed guide bar 115 and the inner flight of belt 110 whose surface 113 yields and frictionally engages the container with sufficient force to rotate the container and in so doing to wrap 14 and press the unadheredportions of the adhesive-bean'hg label to the container. The container with, a label'fully adhered thereto then further is advanced by conveyor 22 beyond said station 11 to the delivery or exit end of the machine for hand or mechanical removal as desired.

As will be observed, all phases of the labelling procedure are effected in a continuous manner from the time of positioning of a container onto the conveyor 22 at the entrance to the machine until its delivery at the exit end thereof. All parts are in continuous motion during this time. In the embodiment shown, two labels are withdrawn with each revolution of head carrying block 38 because two heads 36 are located thereon, unless for some reason there is a container missing on conveyor 22 and feeler arm 58 is not tripped. Failure to trip such arm prevents removal by heads 36 of labels from the magazine 14 as long as no containers C are present on conveyor 22 in a position to arrive at the label-applying station I at a time synchronized with arrival there of a label for applica tion. This avoids waste of labels.

A machine of the character herein described is capable of labelling containers at a rate upwards of 200 per minute without waste. Moreover, since only the minute areas Lu of negligible size actually remain ungummed during application of adhesive, substantially the entire label surface will become adhered to the container. In fact, the ironing or pressing action at station II by belt probably in most cases causes sufficient oozing of adhesive from gummed areas of the label into the ungummed areas Lu as to practically obliterate the latter and insure substantially complete adhesion between labels and containers in all areas thereof.
