9 Claims.

The present invention relates to a machine for applying labels to articles such as bottles. This application is a division of my copending application for Labeling machine, filed July 19, 1939, Serial No. 285,306.

One of the features of the invention is the provision of a movable support which, in its lowest position, receives each bottle orother article to be labeled, and then moves upwardly to a position where a label is applied to and pressed securely onto the article, this motion affordinig the maximum room for the presentation and withdrawal of the article as well as materially reducing the time required for each labeling operation of the machine. compact arrangement of its several instrumentalities, involving the disposal of its label holder between the gum-applying mechanism and the bottle or other article to be labeled.

Other and further objects and advantages of the invention will hereinafter more fully appear from the following description taken in connection with the accompanying drawings in which.

Fig. l is a front elevation of a machine embodying the invention.

Fig. 2 is a side elevation of the machine of Fig. 1.

Fig. 3 is a larger scale fragmentary tion of the gumming apparatus.

Fig. 4 is a sectional view substantially along the line 44 of Fig. 1, showing the label carrier, as well as the article supporting mechanism.

Figs. 5 and 6 are diagrammatic views illustratside 'eleva ing successive portions of the label-gumming operation.

With reference to the drawings, the machine The machine also provides a novel and provides spaced sides or uprights l and 2, Fig. 1,

having journalled in their base portions the main shaft 3, which carries a plurality of cams forcontrolling the several machine movements, as will hereinafter appear. ated from any suitable source of power, not shown, through a one revolution clutch l of conventional construction. The clutch may be operated by a foot treadle, not shown, through any suitable connections.

The principal label-handling instrumentality of the machine is a horizontally reciprocating carrier 5, having suction openings on its underside by which to seize and hold the front or printed face of each label. Said carrier is suitably suspended from an arm 6', projecting from a member 6 which is slidableon a rod 1 and on a guide 8, both of which extend horizontally from The shaft 3 is actufront to rear of the machine and have their support in brackets 9, 9 secured to the upright I.

The label supply is a stack ll, contained in and held nearly upright, edgewise, by a box or holder II, which is adjustably mounted on a suitable bracket H secured to the side member 2. To an extension of this bracket is pivoted at l3 a hollow arm l2, whose free end, in the upper position (Fig. 1) of said arm, is adapted to engage and seize by suction the rear or unprinted face of the outermost or lowermost label of the stack III, for removal of said label from the stack by the downswing of said arm. Said downswing of the suction picker l2 disposes the label in a substantially horizontal position, in or just below the plane traversed by the under surface of the carrier 5; with the arrival of said carrier just over the sopositioned label, the suction on the picker I2 is released, and the suction on the carrier is applied, thereby transferring the label from the picker to the under surface of the carrier, which then moves, as hereinafter described, to expose the label to a glue-applying operation, and then to deposit same on the bottle or other article to be labeled.

For the operation of the suction picker I2, a projecting arm l5 thereof has its outer end pivotally connected to a depending rod l6, whose lower end is pivotally connected to a rocker arm I1, journalled on a horizontal rod or shaft 18. Said arm I! carries a roller l9 which cooperates with a cam 20 on shaft 3; this cam 20 is of the proper contour to produce the up and down swing of the picker l2 in correctly-timed relation to the movement of the label carrier 5.

The suction opening or openings 2| of the picker l2 communicate by an interior chamber 22 with a suction passage 24 extending the full length of the arm; said passage, by means of a flexible hose 23 or the like, is connectedto a valve mechanism 25, having a suitable connection 26 to vacuum. Likewise the several suction openings 21 of carrier 5' communicate by an interior chamber 28 and by a flexible hose connection 29 with said valve mechanism 25. The latter is not here illustrated in detail, since its operation will be understood by those skilled in the art; any suitable valve mechanism may be employed to control, in properly timed relation, the application of suction to and the release of suction from the picker l2 and carrier 5.

After a label has been transferred, as hereinbefore described from the picker l2 to the carrier 5, the latter moves rearwardly (toward the left, Figs. 2 and 4) for the application of adhe- .theshaft3. v

sive to the label. This adhesive is applied first to one-half of the label as the carrier moves rearwardly, and then to the other half of the label as the carrier moves forwardly, this adhesive being supplied by a pair of parallel adhesiveapplying rollers 30 and 3|, Fig. 3, supported by the side walls of a box 32, which holds the fluid adhesive, and which is supported by a rocking plate 33. The plate is mounted on a shaft 34 extending between the uprights l and 2, and

rocking of the box is effected through a rod 35' connected at its upper end by a pin 36 and slot 31 to the bracket, and at its lower end to an arm 38, which, like the arm I1, is journalled on the shaft l8. A follower 38' on the arm 33 cooperates with a cam 39 on the shaft 3, to produce the rocking 'of box 32 at the proper times. The rollers 30 and 3| are mounted on shafts l3 and 4| journalled in the opposite side walls of the box 32, and these shafts have interengaging gears 42 and 43, Figs. 1 and 3, positioned outside of the box for assuring a rotation of the two rollers in opposite directions. As shown in Fig. 3, a comb I is positioned between the rollers, and has opposed edges engageable with the peripheries of the rollers to control the amount of adhesive carried by the roller surfaces. The gum box 32 supports at each end a scraper 15' of conventional construction, for cooperation with each of the rollers 30 and 3|.

For driving the rollers 30 and 3|, a shaft 46 is journaJled in a bracket 41 mounted on the plate 33, Fig. 1. The shaft 46 has on the end thereof a sprocket 43 connected by a chain 43 to a sprocket 50 on the main driveshaft 3. It will be noted that the rotation of the rollers 30 and 3| is such that the upper surfaces of the rollers move toward each other, as indicated by the arrows, Fig. 3, so that the roller surfaces will be moving inthe same direction as the label when either roller is engaged thereby.

, The label carrier 5 is moved by a link 5|, which connects the carrier to the lower end of an arm 52 journalled on a shaft 53, which in turn extends .between the upper ends of the uprights I and 2. Integralwith the arm 52 is a depending arm SI, the outer end of which is connected by a rod 55 to an arm 56 journalled on the shaft upper end of a rod '62 which is vertically slidable II. The arm 56 carries a cam follower 61 engageable, as shown in Fig. 1, with a cam 38 on As the label carrier 5 moves inwardly of the machine (to the left, Fig. 2), the box 32 is tilted counterclockwise, Fig. 3, to bring the right-hand roller 3| 'against the underside of the label on the carrier, thereby gumming the right-hand half of the label from its middle portion to its right-hand edge, as shown in Fig. 5. As thecarrier reverses, and begins its movement to the right, Fig. 3, the box is rocked clockwise, to bring the left-hand roller 30 against the underside of the label for applying gum or adhesive to the left-hand half of the label, from its middle portion to its left hand edge, as shown in Fig. 6. In this way, there is never any chance for the label, in its contact with either gumming roller, to wrap around or follow the roller surface, since the initial contact in each instance is with the labels middle portion, and never with a leading ed e of the label. The carrier continues its movement toward the front of the machine (to the right, Fig. 2), until the carrier is in the label'- depositing position, viz., the outer limit of its reclprocatory travel.

in a guide member 63. The latter is supported on a cross bar 64 extending between the uprights and 2. The member 6| has connected thereto a link 65, the lower end of which is connected to an arm 66 turnable on the shaft I8. This arm 63 has a cam follower 61, Fig. 4, cooperating with a cam 58 on the main shaft 3. The cam is so shaped as to raise the bottle a into a position directly beneath and practically flush with the label, as soon as the suction carrier 5 reaches its label-depositing position, so that-the adhesivecoated lower surface of the label will contact the bottle, immediately upon the release of the suction exerted on said label by the carrier 5. The bottle ais held against undue displacement on its support by the lateral wings f thereon, best shown in Fig. 1.

As soon as the label has been released from the suction carrier and applied to the upper side of the bottle, the carrier moves rearwardly (to the left. Fi s. 2 and 4), and the label presser 69 positioned above the bottle, moves downwardly, and assures a secure attachment of the labelto the bottle. The label presser is carried on a vertically reciprocal bar 10, slidable in a bracket II, which in turn is secured to a cross bar 12 extending between the uprights I and 2. The upper. end of-the bar I0 has a notch 13 .to receive the projecting end of. an arm 14 turnable on the same shaft 53 on which the arm 52 is mounted. Integral with the arm 14 is a second arm 15, and thefree end of this arm is connected by a rod 16 to an arm 'I'l turnableon the shaft i8. The arm II has a cam follower l3 cooperating with a cam 13 on the shaft 3 by which the label presser is moved. The presser 69', as shown, has a sponge rubber or other resilient pad 80 on the underside thereof, for conforming to the contours of the bottle and for assuring a pressure over the entire surface of the label.

In operation, before the above described rearward movement of carrier 5 takes place, the picker |2 will have swungdownwardly, carrying into a horizontal position the next-removed label from the stack III. Then, as the carrier moves 'rearwardlmthere is a momentary dwell of same 1 lease of suction by the picker and the application of suction to the carrier procures the transfer of the label to the carrier. Then the carrier's rearward movement is resumed, and the, picker 12 moves upwardly into the full line position of Fig. 1, in readinessto the stack,

As the carrier moves toward the rear of the machine, the gumming tray is rocked counterclockwise, Fig. 2, to bring the right-hand gumming roller against the underside of -.the label, when the rollers and label are substantially in the relative positions of Fig. 5, and thereby apply gum to the right-hand half 'of the label during the continued movement of the carrier to the left. The movement of the carrier is then reversed, and simultaneously therewith the gum- The bottle a or other article to be labeled, is 7 ming tray is rocked clockwise, Fig. 2, to bring the left-hand roller into position for engagement with the label, as shownin Fig. 5, thereby applying gum to the left-hand half of the label as the carrier moves toward the front of the machine. The portions of the label to which the adhesive is applied successively by the rollers 30 and 3| are shown in Figs. 5 and 6 respectively remove the next label from by the enclosing brackets in these figures. The carrier then continues its forward movement, until it is in labelapplying position directly over the bottle, in which position it remains'long enough for the bottle to be elevated to engage the label, the suction in the carrier being at this time out ofi to release the label, and the carrier is then withdrawn to its original labelpicking position. As soon as the carrier is withdrawn, the label presser is moved downwardly, and assures a secure attachment of the label to the bottle.

While the carrier is in label-applying position, the picker arm l2, which has been in the raised position of Fig. 1, with the end thereof in engagement with the bottom label in the stack of labels, has suction applied thereto to pick up the bottommost label and transfer it by downward movement of the arm, to a position directly beneath the position of the carrier when the latter is in label-picking position. All of these machine movements are controlled by the cams on the shaft 3, and thus occur in predetermined relation to each other, the cams being suitably designed to control the machine movements in the proper sequence. Although I have shown my improvements, for purposes of illustration, in connection with a semi-automatic labeling machine wherein the articles to be labeled are manually presented to and withdrawn from labeling position, it will be understood that my invention is not so limited, but is-applicable to any and all types of labeling machines.

The claims of the original application, of which this is a division, are directed to the structure by which adhesive is applied to the label, together with the mechanism for transferring the label to and from the cutting means. This divisional application incorporates claims directed to the label applying instr-umentalities and to the particular arrangement of the several instrumensupport, a reciprocable label carrier, the latter having a label applying position in line with the movement of the support, means for moving the support toward the carrier, whereby a label on the carrier is applied to an article on the support, and means for pressing the label onto the article after withdrawal of the label carrier from labeled applying position.
