7 Claims. (01. 216-55) This invention relates to a container labeling machine and particularly to a bottle labeling machine.

The invention has for an object to provide a novel and improved labeling machine adapted for the application of a plurality of labels to a container being continuously moved through the machine and in which provision is made for changing the position of the container during such continuous movement to present different faces thereof in operative position to successive label applying mechanisms for the application of labels to different portions of the container in a novel, rapid and efiicient manner.

With this general object in view and such others as may hereinafter appear, the invention consists in the labeling machine and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claims at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention, Fig. 1 is a plan view of a labeling machine embodying the present invention; Fig. 2 is a vertical cross sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is an enlarged cross sectional view of a portion of the label applying mechanism; Fig. 4.- is a cross sectional plan view taken on the line 4 l of Fig. 3;

Fig. 5 is a plan view detail of a portion of the mechanism shown in Fig. 3, to be hereinafter referred to; Fig. 6 is a side elevation of adhesive applying mechanism and associated safety control mechanism, to be referred to; F1g. 7 1S a plan view, partly in cross section, as viewed from the line 'l---'! of Fig. 6; and Fig. 8 is an enlarged detail view of gearing shown in Fig. 1.

In general, the present invention is illustrated as embodied in labeling machine of the rotary type having provision for operatively supporting successive containers in spaced relation and for continuously moving the containers in a circular path into operative relation to successive label applying mechanisms adapted for the application of labels to the continuously movlng containers. Provision is made for rotating a container on its axis during the continuous movement thereof to dispose different faces of the container in operative relation to successive label applying devices whereby to enable the application in a simple, rapid and superior mannerof labels to different portions of the container during the continuous movement of the container through the machine.

The illustrated label applying mechanism includes a continuously rotated spider provided with a plurality of suction heads adapted to withdraw successive labels from a supply thereof and to support the labels during the application of adhesive thereto. The continuously rotated suction head spider is rotated in timed relation to the rotary bottle supporting mechanism and is arranged to be operated to afiix successive labels to successive containers being conveyed in spaced relation into operative positionto the label applying mechanisms. Provision is also preferably made for firmly pressing the applied labels upon the containers during the continuous movement thereof. Provision is also made in the preferred embodiment of the invention for controlling the operation of the continuously operated label applying mechanism in a manner such as to prevent operation of the adhesive applying device in the event that no label is withdrawn from 1 the label supply.

Referring now to the drawings, the invention is herein illustrated as embodied in a continuously operated rotary labeling machine having provision for applying successive labels to 0pposite sides of a container, herein shown as a bottle, and in which provision is made for rotating the container on its axis after a label has been affixed to one face thereof to present the opposite face of the container in operative position to receive a label from a succeeding labeling device during the continuous movement of successive bottles through the machine. As herein shown, the illustrated labeling machine is provided with a rotary container supporting and conveying plate I 0 mounted for continuous rotation about a stationary central supporting shaft I2. The plate I0 is provided with a plurality of circumferentially spaced slide bearings l4, each bearing having a container supporting and elevating platform l6 mounted for vertical reciprocation therein and upon which the containers are supported and conveyed in spaced relation into operative position to successive label applying mechanisms, indicated generally at I8, 20.

In general, in the operation of the machine, the containers to be labeled are delivered to the machine on a supply conveyer 52 and are transferred onto successive platforms It by an intake spider or starwheel 54, and after a label has been applied to one side of the container by the labeling mechanism 18, the container is rotated on its axis to present the labeled face in operative relation to reciprocally and radially mounted presser pads 55 arranged to firmly press the loosely attached label against the container during the continuous rotation of the machine. The container is then carried into operative relation to receive a label on its opposite side at the second labeling station 20 and thereafter the container is again rotated 180 to present the container in operative position to have the second label firmly pressed against the same by the radially reciprocal rotating presser pads 55. The completely labeled container is then guided out of the machine and transferred to the discharge end of the conveyer 52 by a discharge spider 51 to be delivered from the machine.

As shown in Fig. 2, the supporting disk I is keyed adjacent the upper end of an elongated sleeve 22 mounted for rotation upon the central shaft I2 and is arranged to be continuously rotated through driving connections including a main drive pulley 24 mounted fast upon one end of a shaft 26 journaled in a bracket 28 attached to the base 30 of the machine frame. The other end of the shaft 26 is provided with a bevel gear 84 fast on the lower end of the elongated sleeve 22. The vertical shaft I2 is supported at its lower end in a hub member 36 formed in the base 30 and is held from rotation by a key 38 and set screw 40, as illustrated. A thrust bearing 42 is interposed between the top of the hub 36 and the underside of the flanged end 44 of the sleeve 22. The sleeve 22 is also rotatably supported within an outer bearing member 46 mounted on the platen 48 of the machine frame and a second thrust bearing 50 is interposed between the upper end of the bearing member 46 and the underside of the disk I0, as illustrated. Thus, in the operation of the machine, the disk I0 is continuously rotated to convey the containers supported on the platforms I6 in a circular path into operative relation to the labeling mechanisms I8, 20.

The containers to be labeled are delivered to the machine on the supply conveyer 52 and successive containers are transferred in predetermined spaced relation from the supply conveyer 52 to successive container supporting platforms I6 by the continuously rotated intake spider or starwheel 54 mounted for rotation with a vertical shaft 56 arranged to be rotated in timed relation to the rotation of the conveying disk I0. As herein shown, the containers being transferred are arranged to pass across a bridge plate 58 and a guide rail 60 cooperating with the starwheel 54 is arranged to guide successive containers onto successive supporting platforms I6 during the continuous operation of the machine.

The platforms I6 are disposed in a horizontal plane in alignment with the conveyer 52 and bridge plate 58 during the transfer operation, and immediately after a container has been transferred thereon, the platform is arranged to be elevated to present the upper end of the container in clamping engagement with a yieldingly mounted clamping member, indicated generally at 62, carried in the outer end of each radial arm 64 of a spider 66 mounted for rotation about the central shaft I2, the clamping members 62 being arranged in vertical alignment with their respective container supporting platforms I6 and rotated in a circular path along with the platforms I6.

As illustrated in Fig. 2, the platforms I6 are mounted upon the upper ends of tubular sleeves rotatably and reciprocally mounted in the slide bearings I4 and an upstanding pin 12 fitted into the lower end of each sleeve I0 is provided with a roller 14 arranged to cooperate with a stationary annular cam 16 formed at the periphery of the flanged portion I8 of the bearing member 46. The tubular sleeve I0 is mounted for rotation at a subsequent time relative to the pin 12 as will be described, and in order to prevent rotation of the pin 12 and to hold the cam roll I4 in alignment with its cam I6, an extended portion of one of the cam roll supporting arms is arranged to engage the outer periphery of the stationary cam, as illustrated.

The platforms I6 and sleeves I0 are arranged to be held from rotation on their axes until the proper time in the cycle of operation of the machine by the cooperation of a concave portion 82 of a partial gear member 84 with the periphery of a stationary disk 86, the partial gear being fast on the lower end of the sleeve I0 and the stationary disk 86 being keyed to the outer bearing member 46. As will be described, the partial gear 84 is provided with gear teeth for cooperation with gear teeth formed at predetermined portions of the stationary disk 86 to effect rotation of the platform I6 and of the container carried thereby through an angle of 180 after a label has been affixed to one side of the same by the label applying mechanism I8. In order to facilitate relative rotation of the sleeve 10 on the pin 12, a roller bearing 88 is provided between the flanged lower end of the sleeve I0 and a collared portion 90 of the pin, as illustrated in Fig. 2.

As herein shown, each clamping member 62 comprises a cap or hood member 92 fast on the lower end of a pin 94 mounted for rotation and vertical reciprocation in a slide bearing 96 formed in the end of the radial arm 64. A coil spring 98 provided with end caps I00 is interposed between the top of the hood member 92 and the underside of a roller bearing I02 engaged with the lower surface of the bearing member 96. The hood member 92 is provided with a conical opening I04 on its underside for engagement with the upper end of the container and the conical opening may and preferably will be provided with a rubber or similar yieldable frictional lining I06 to effect a frictional grip on the top of the container. In operation, the coil spring 98 is arranged to yieldingly urge the hood 92 against the top of the container to clamp the same between the hood and the platform I6 when the latter is elevated, and the roller bearing I02 facilitates rotation of the clamping unit 62 relative to its supporting member 96 when rotation of the platform and container is effected, as will be described. The upper end of the pin 94 is provided with a head I08 arranged to engage the upper surface of the bearing member 96 to serve as a stop to limit the downward movement of the clamping unit.

The upper spider 66 on which the clamping units 62 are carried is arranged to be rotated with the lower container supporting disk I0 through connections including an intermediate rotary supporting disk I I0 keyed to the uppermost end of the continuously rotated sleeve 22, the disk I I0 forming a part of the label wiping or pressing mechanism to be described. The upper spider 66 is provided at its lower end with a pair of opposed connecting arms II2 keyed to the spider and the outer ends of the arms I I2 are connected to the intermediate disk IIO for rotation therewith by bolts II4 and nuts II6. Spacing collars II8 are provided between the arms H2 and the driving disk H0 in order to avoid a stationary cam I20 keyed to the central shaft I2 and also forming a part of the pressing or wiping mechamsm.

From the description thus far it will be observed that in the operation of the machine successive containers to be labeled are transferred from the supply belt 52 onto successive supporting platforms I6 and are elevated to present the tops of the containers into clamping engagement with the yieldably mounted clamping units 62. The containers are thus firmly supported between the platforms I6 and the clamping units 82 and are held from rotation on their axes by the cooperation of the member 84 in sliding engagement with the stationary disk 86 in which condition the containers are presented to the label applying mechanism I8 to receive a label on one side thereof.

As illustrated in general in Fig. 1, the label applying mechanism I8 includes a plurality of suction heads or pads I22, herein shown as four, mounted upon the outer ends of radially extended arms I24 carried by and arranged for reciprocation in a continuously rotated spider I26. As shown in Fig. 2, the spider I26 is keyed to the upper end of a hollow shaft or driving sleeve I28 and is arranged to be rotated in timed relation to the container supporting and conveying disk I by a gear I30 keyed to the lower end of the sleeve I28 and which meshes with a lar e diameter gear I32 keyed to the sleeve22- of the container supporting unit. The driving sleeve I28 is mounted for rotation about a central stationary shaft I34 fixedly supported at its lower end in a hub I36, formed in the base 38, by a key I38 and set screw I40. A thrust bearing I42 is interposed between the upper end of the hub I36 and the underside of the flanged end I44 of the sleeve to support the sleeve for rotation about the stationary shaft I34. The sleeve I28 is further supported in an elongated bearing member I46 having a flanged portion I48 attached to the platen 48. Thus, in operation, the spider I 26 and the radially mounted suction pads I22 are rotated continuously in timed relation to the containers being continuously moved through a circular path by the rotary disk III.

In operation, successive suction pads I 22 are arranged to be reciprocated in the spider I26, during their continuou movement, to engage and withdraw the endmost label in a stack I50, and as shown in Figs. 1 and 3, each radially extended arm I24 is provided with a roller I52 arranged to cooperate with a cam path I54 formed in a stationary cam disk I56 keyed to the upper end of the central stationary supporting shaft I34.

Provision is made for reciprocating the stack of labels I55 laterally in timed relation to the movement of the suction pads I22 into engagement therewith during the continuous rotation of the spider I26 and as herein shown, the stack is supported in a magazine I58 mounted for lateral reciprocation in a slide bracket or track I60. The label supporting magazine I58 is arranged to be reciprocated through connections from the ear I30 including a pinion I62 in mesh with the gear I36 and fast, on a crank shaft I64 journaled in a bracket I66 attached to the underside of the platen 48, as shown in Fig. 2. The upper end of the crank shaft IE4 is provided with a crank arm I68 fast thereon and connected by a link I10 to an arm I12 fast on the lower end of a vertical rocker shaft I14 supported in a suitable bearing H formed in the platen 48. The upper end of the vertical shaft I14 is provided with a slotted arm I 76 connected by a link I I8 to the magazine I58. Thus, in the operation of the machine, the label magazine is moved laterally at the same rate mounted upon a shaft 2|: carried between 01' speed as the continuously rotating suction pads I22 in a manner such that when a suction pad I22 reaches its maximum limit of extension, the stack I50 will be in longitudinal alignment with the endmost label, as shown in Fig. 1. Upon continued rotary and lateral movement of the Dad I22 and stack I50 respectively, the endmost label will be withdrawn from the stack durin the retracting stroke of the suction pad, the magazine continuing its lateral movement to the left viewing Fig. 1 along with the pad during such retracting movement. Thereafter, the magazine is returned to its initial position, to the right viewing Fig. l, in readiness for cooperation with a succeeding suction pad I22.

As shown in Figs. 3, 4 and 5, each suction pad I22 may comprise a yieldable or resilient material such as rubber, and is provided with a plurality of suction openings I80. The pad I22 is mounted on the outer end of a hollow head I82 forming a suction chamber and the chamber is connected with a source of suction through ports I 84 formed in the head and a flexible conduit I 86 connected by a nipple I87 to an individual valve unit I88, four of which are carried by the spider I26. Each valve unit I88 is provided with a valve stem I90 having a reduced diameter portion I 94 arranged, in its open position,for align ment with opposed ports I92, I96 of the valve I88 to permit communication between the conduit I86, connected to the port I94, and a second conduit I 98 connected to the port I96. The second conduit I 98 is connected to the outer end of a radial channel 200, four of which are formed in the lower portion of the rotary spider I26. The inner end of each radial channel is arranged to communicate with an arcuate chamber 202 formed in a stationary member 204 fixed to the upper end of the elongated supporting bearing I46, the member 204 being mounted for rotary adjustment with respect to the bearing and held in its adjusted position by a set screw. A pipe 208 connected to the stationary member 204 andin communication with the arcuate channel or chamber 202 may be connected to any suitable or preferred form of suction creating means, such as a vacuum pump, not shown. Thus, in the operation of the machine, a label is withdrawn from the magazine by a suction pad I22 as it is continuously moved into and from engagement therewith. The label magazine may be of known construction having provision for urging the stack forwardly in the magazine, and provided with the usual means for retaining the labels in the magazine until withdrawn by a suction pad, as described.

As illustrated in Fig. 2, provision is made for applying a. film of adhesive to the label supported by the suction pad I22 during continuous movement thereof and as herein shown, the label is brought, into engagement with an adhesive applying roller 2! disposed in the path thereof during movement of the suction pad I22 therepast. The adhesive applying roller H0 is rotatably spaced arms 2, 2H5 fast on a vertical rocker shaft 2I8 journaled in a bracket 22;: attached to the machine frame. Provision is made for rocking the roller 2I0 into and out of contact with an adhesive supply roll 222 during the intervals between the passage of a label supporting pad therepast, and as herein shown, the lower end of the rocker shaft 2I8 is provided with an arm 22,4 fast thereon and connected by a link 226 to an arm 228 fast on the lower end of a vertical shaft 230 journaled in a bearing member 232 attached to the platen 48, as shown in Fig. 6. The arm 228 isprovided with a roller 234 arranged to cooperate with a cam 236 fast on the driving sleeve I28. A spring 238 connected to the arm 228 is arranged to hold the roller 234 against its cam. The cam 236 is provided with four lobes 240 arranged to effect oscillation of the adhesive applying roller 2I0 into and out of engagement with the adhesive supply roll 222 in timed relation to the rotation of the suction pads. The applying roller 2I0 is arranged to be yieldingly urged into engagement with the pad and label by the provision of a yieldable connection 242 between the arm 224 and link 226, as shown in Fig. '1, the connection being arranged to effect positive movement of the applying roller 2 I into engagement with the supply roll 222.

The adhesive supply roll 222 is rotatably supported in a supply tank 252 and is arranged to be rotated by a chain and sprocket connection 254, as shown in Fig. 7, the driving sprocket 256 being keyed to the lower end of the driving sleeve I28, see Fig. 2. The adhesive is continuously supplied to the vertically disposed supply roll 222 from a pipe 258 connected to a pump 260 which is arranged to reeirculate the adhesive received thereby from a pipe 262 connected with the supply tank 252.

In the normal operation of the machine, the adhesively coated label carried by the suction pad I22 will engage the periphery of the container supported on the platform I6 when the pad I22 and platform I6 arrive in alignment with each other as shown in Fig. 1. It will be observed that the arcuate chamber 202 is discontinued immediately prior to the arrival of the pad I22 into label applying position to cut off the suction therefrom in order to permit the label to leave the pad and adhere to the container, and in order to further relieve the label from the suction at this time, a vent opening 244 is pro vided in the stationary disk 204 arranged in alignment with the inner end of the radial channel 200 when the suction pad arrives in label applying position to open the suction pad chamber to the atmosphere.

When the label, in its flat condition, is thus applied to a round container, it is merely tacked on, adhering to an area sufiicient to hold the label in position for a subsequent wiping or pressing operation to firmly set the label, as will be described. It will also be observed that the face of the label supporting pad I22 is arcuate in form for engagement with the container being moved therepast in a circular path.

Referring now to Figs. 3, 6 and '7, provision is made for controlling the operation of the labeling mechanism to render the adhesive applying device inoperative in the event that a label is not withdrawn from the magazine, as above described, whereby to prevent the application of adhesive to a suction pad having no label. As illustrated in Fig. 3, the valve stem I90 of the valve unit I88 is provided with a piston head 264 at its upper end slidably mounted in a cylinder chamber 266, the piston being urged downwardly to the lower end of the chamber by a spring 268 to close the ports I94, I96. Immediately prior to the arrival of a suction pad into label withdrawing position, with the pad in engagement with the endmost label in the stack, the valve stem is elevated to open the valve by engagement of the lower conically shaped end 210 of the valve stem with a stationary cam 212 mounted on and adiustably secured to the stationary supporting bearing I46. Upon opening of the valve, suction is created at the openings I in the suction pad to effect withdrawal of a label and when the openings I80 are closed by a label carried by the pad, the piston head 264 is maintained in an elevated position in the chamber 266 by the suction created in the chamber through a conduit 214 connected between the nipple I81 and the upper end of the chamber to hold the valve in an open position during the normal operation of the device, the piston being limited in its upward position by a shouldered portion of the cylinder, as shown. However, in the event that the label is missing from the pad after retraction of the pad from engagement with the stack, atmospheric air entering the suction openings I80 in the pad reduces the vacuum in the system to such an extent that the spring 268 is permitted to effect downward movement of the piston member to close the valve. As herein shown, when the valve stem is in its lowered position, the lower end 210 thereof is presented in horizontal alignment with or in the path of a curved lever or safety arm 216 pivotally mounted on the vertical shaft 230. The safety arm 216 is connected by a slotted link 218 to an arm 28!) fast on the rocker shaft 2I8, the arm 280 having a pin 282 extended into the slot, as shown. The safety arm 216, as shown in full lines in Fig. 7, is normally urged in a counter-clockwise direction by a spring 284, the slot 286 permitting freedom of movement of the adhesive applying roller 2I0 relative to the safety arm 216 during normal operation of the machine. In the operation of the device, when the pressure in the chamber 266 rises, indicating that a label is missing from the pad, the valve stem will drop down into its lowered position and the lower end 210 of the stem will engage and rock the arm 216 in a clockwise direction, as shown in dotted lines in Fig. 7, the closed end of the slot 286 engaging the pin 232 to hold the adhesive applying roller 2 I0 in its retracted position during the travel of the pad I22 therepast. The safety arm 216 will return to its normal position as soon as the end 210 of the stem passes beyond the end of the arm 216, and during the continued operation of the machine, the stem is again elevated and reset by the cam 212 to open the valve ports I94, I96 when the pad again arrives in label withdrawing position, as described, at which time the radial channel 200 is again in communication with the arcuate chamber 202.

In the operation of the rotary label applying apparatus thus far described, it will be observed that the label is loosely attached by the applyin mechanism I8, the label adhering to a round container merely along an area adjacent the point of contact of the applying pad and the container. As illustrated in Fig. 1, provision is now made for rotating the container supporting unit IS on its own axis through to present the labeled side of the container facing inwardly in alignment with the radially reciprocal wiper or presser pads 55 and also to present the unlabeled side of the container facing outwardly for cooperation with the succeeding label applying mechanism 20 during the continued movement of the container in a circular path. As herein shown, the partial gear member 84 is provided with opposed sets of gear teeth 290 one set of which is arranged for cooperation with gear teeth 292 formed on the stationary disk 86 and, in operation, immediately after the label is applied by the labeling mechanism I8, one set of teeth 290 engages the teeth 292 to effect rotation of the supporting unit IS on its own axis in a clockwise direction, the concave portion 82 in engagement with the stationary disk 86 leaving the disk upon initial engagement of the teeth and the opposed concave portion being presented int-o cooperative engagement with the disk the end of the rotary movement of the container supporting unit on its own axis. As illustrated in detail in Fig.- 8; the uncut periphery of the stationary disk 86 is coextensive with the pitch line 87 of the gear teeth 292 formed therein, and the arcuate or concave portions 82 of the partial gear 84 are tangent to the pitch line 89 of the gear 84. The disk 88 may be cut away or rounded slightly adjacent the end tooth spaces 9!, 93 as indicated at 95 to provide clearaims for the ends of the concave portions when leaving or reentering engagement with the periphery of the disk 86, the initial engagement of the teeth 2% with the teeth 292 being illustrated in dotted lines in Fig. 8.

The label p-re'sser pads 55 are mounted upon the ends of radially extended arms 294 slidably inoiinted in the rotar disk llil, and each label presser pad is arranged to be reciprocated in the disk Hit by the cooperation of an individual cam roll 2%, carried by each arm 291i,- with a cam 298 formed in the stationary I20. In the operation of the machine; a presser pad 55 is arranged to be pressed into en agement with the label as soon as rotation of the container on its axis terminates, as described, and is arranged to remain in engagement therewith for a short time during the continued operation of the machine to firmly set the label, whereupon the presser pads are retracted. In order to provide auxiliary support for the sup orting units l6 during the pressing operation, a stationary arouate rail 3%- may be supported for engagement with the periphery of the platforms, as illustrated, in Fig. l, the rail 30!} being supported by suitable brackets 3?)! extended fio'mthe platen 48.

During the continued operation of the machine, the container and its supporting unit I6 is maintained with the unlabeled face of the bottle in an outward position by the cooperation of the concave portion 82 with the periphery of the stationary disk 86 and is presented to the second label applying station 20 where a label is applied to the outer face of the container on the opposite side from the previously applied label. Since the labeling mechanism at station 20 is similar in construction and mode of operation to the labeling station [8 previously described, further description thereof is deemed unnecessary.

Immediately after the application of the second label, the container supporting unit I6 is again rotated through 180 by the cooperation of the second set of gear teeth 29!! with gear teeth 302 formed on the stationary disk 86 to present the second labeled side of the container facing inwardly for cooperation with the presser member 55 to effect Wiping of the loosely attached label into firm engagement with the container in a manner similar to that previously described. A similar auxiliary supporting rail 304 may be provided adjacent the periphery of the platforms it during the pressure applying operation. Thereafter, the pressure pads 55 are retracted and the elevating platform unit is permitted by the cam 16 to descend to its original position to present the platform [6 in a plane in horizontal alignment with the bridge plate 58 at the discharge station. The completely labeled container is then guided off its platform I6 by a cutout portion of the stationary guide railBB and is transferred across the bridge plate 58 onto the discharge end of the conveyor 52 by the discharge spider 51 to be carried away from the machine. As illustrated in Fig; 1, the discharge spider 51 is secured to the upper end of a vertical shaft 59; and is arranged to be driven in timed relation to the inlet spider 54 through a chain and sprocket connection 306 connecting the shafts 58 and]! and arranged to run around a driving sproeket 308 fast on the sleeve I28, as shown in Fig. 2.

Referring to Figs; 1 and 2, it will be observed that the spider 66 is keyed to the arms H2; and adjustably secured on the shaft I 2 by the collar 320 and locking screw 322. In practice the shaft I2 is made of greater length than shown in Fig. 2 to permit vertical adjustment of the spider to accommodate bottles or containers of different heights. Suitable fillers may be used for supporting the lower end of the hub of the spider.

Although the present machine has been herein illustrated and described as adapted for operation upon round bottles or bottles having a cylindrioal surface, it will be apparent that the machine may be used with equal advantage for applying labels to bottles or other containers of diilerent shape, such as square, rectangular or oval bottles having flat, convex or concave surfaces to which the labels may be applied.
