14 Claims. (CL 216-55) automatic type in which the article to be labeled is placed in a label-receiving position by hand. and concerns more especially improved means for transferring labels from a magazine to an articletobelabeled.
The usual procedure in applying labels me--.
chanically is to withdraw ungummed labels one by one from a magazine, then to transfer the label to the label-applying station where the article to be labeled is properly supported, applying gum to one face of the label while the latter is in transit; and pressing the gummed surface of the label into contact with the article.
The certain removal b mechanical means of labels one by one from a magazine constitutes a problem .which is not too easily solved; the application of gum to one face of the label during transit without daubins the other face of the label or waste of gum presents another problem;
v while the accurate positioning of the gummed 1 surface of the label relatively to the article designed to receive it involves additional dimculties. Moreover, to satisfy demands of users, the
machine must be capable of repeating its operative cycle at very frequent intervals, for example at the rate of approximately 65 times a minute, or in other words as fast as a skilled operator can present articles one after another in position to receive the labels.
Picker devices for removing labels from the magazine are of various types, but suction pickers and adhesive pickers are those most commonly employed. Of these two types the adhesive picker is the more reliable as a means for removin labels from the magazine, but the use of this type of picker involves certain disadvantages. particularly the dimculty, when'using this type of picker of providing a uniform coating of gum over the entire surface of the label. After removal of the label from the magazine the label may be conveyed or transferred with a high degree of certainty from one point to another by a suction carrier or transfer device, but a suction picker is not altogether reliable for picking labels from the is to provide a machineof the above type wherein an adhesive type picker is used for removing the label from the magazine. but with provision for. insuring uniform distribution of adhesive over the surface of the label. A further object is to provide mechanism wherein a label removed from the magazine by an adhesive type picker is delivered by a suction carrier to the labeling station but with provision'for preventing contact of the. suction carrier with the adhesive coating on the picker. Other and further objects and advantages of the invention will be pointed out in the following more detailed description and by reference to the accompanying drawings wherein Fig. l is a fragmentary tic side elevation, partly in section, of so much of a labeling machine embodying the present invention as is necessary to illustrate the novel features;

The general construction of the machine may be similar to that illustrated in the patent to Holm 2,257,055, September 23, 1941, which discloses a machine of the semi-automatic type. At the front of the machine there is arranged an article supp rt -2 upon which is placed the article I, for example a bottle which is to receive the label. Directly above'the article support there is arranged a fixed guide 4 in which slides the stem of a label Dresser i, the stem being moved up and down at the proper intervals by means of a lever B (pivotally supported by a shaft W) and a linkfi the latter receiving its motion from a suitably contoured cam on a drive shaft S journaled in the base of the machine.
In accordance with the present invention a shaft I (Fig. 3) is arranged to turn about a horizontal axis extending from front to rear of the turned step by machine: the shaft being mounted to turn in fixed journal bearings 2, carried by the frame and bein step intermittently by means of a ratchet wheel 8 (Fig. 2) fix d to the shaft and a pawl ll which engages the teeth of the ratchet wheel. This pawl. as shown in Fig. 2, is pivotally connected tothe forward end of a rod Ii which slides in a guide I21 and whichis urged forwardly by means of a spring it; The rear end of the rod is pivoted to one arm of a bell crank lever whose other arm has a cam follower roll l4 ngaged by a cam I! fixed to a power driven shaft It The cam it provides the driving force for turning the shaft I, while the spring I! advances the'pawl II in a forward direction to engage the next successive tooth of the ratchet wheel. As illustrated. the shaft I is provided with a brake drum I'l (Fig. 8) which is embraced by a brake band it which opposes frictional resistance to the turning of the shaft ll so that the shaft comes to rest instantly when the pawl Ill ceases its rearward movement. Any other customary and appropriate means for holding the shaft I fixed in the position to which it is turned by the pawl may be substituted for the brake drum and band. if
desired. Likewise instead of a pawl and ratchet drive any other customary intermittent drive may be employed such for example as the well-known Geneva movement.
Fixed to the forward end of the shaft 1 is a drum I! which is provided with a plurality of symmetrically disposed outstanding bosses 20, 20, 20", 20, 20 and 20'. As illustrated there are six of these bosses, the outer flat faces of which are related like the faces of a regular hexagon. The axial thickness of the drum is sufllcient to accommodate labels of the maximum length which are to be applied and the circumferential width of the face of each of the bosses is such as to accommodate a label of the maximum width which is to be applied.
Preferably picker plates 22 (Fig. independent of the bosses 20, etc., are secured to the bosses, for example by meansof screws or bolts 01' in any other appropriate way. These picker plates 22 may be of any suitable material, for example metal, plastic, vulcanized rubber or the like and each plate has a substantially flat outer surface for contact with a label. As illustrated in Fig. 5,
these plates have elongate slots 23 designed to illustrated, the magazine is mounted in a carrier 24 arranged to slide in fixed guidesiiiz the magazine being arranged to move in a th which is perpendicular to the face of the picker plate 22 on the boss 20 of the drum I! when the drum is arranged as shown in-Fig. 2. The magazine is urged downwardly in this direction by a spring 26, but is held upwardly away from the picker plate 22, except at the instant at which a label is to be transferred to the picker face. For this purpose the magazine carrier may be provided with a lug 21 which is engaged by the arm 28 of a lever which has a second arm 29, preferably resilient, provided at its end with a cam-engaging 75 drum is when the parts occupy the position element 30. This element 80 normally engages a circumferential dwell portion of a cam 3 I mounted on a driven shaft 32, the cam having an active portion which, when opposed to the follower member 30, permits the spring 26 to move the mags.- zine downwardly. thereby to engage the lowest label with the picker plate 22.
Adhesive is supplied from a tank or box 38 within which is arranged a pickup roll 34 mounted on a driven shaft 38. This pickup roll delivers adhesive to a roller 36 having frictional engagement with the roll 34, a scraper 31 being provided to remove excessive adhesive from the roll 84. A shaft 38 provides a fulcrum for an elongate leverarm ll" which forms a guide for a sleeve 3! which is urged outwardly along said arm 18' by a spring (not shown) and which carries a gumaDDlying roll 40 at its lower end. The lever arm 28 has a rearward extension 4| which is pivotally connected to the upper end of a link 42 whose lower end is connected to one arm of a lever provided with a cam follower roll which engages a cam groove in a cam 43 mounted on a driven shaft 44. The cam groove in this cam 43 is so shaped as at the proper interval to swing the lever arm 38' upwardly so as to carry the gum-applying roll 40 across the entire width of the exposed face of the picker plate 22 mounted on the boss-20 when the parts are positioned as shown in Fig. 2. While this mode of applying gum to the picker plate is desirable it is to be understood that other customary devices conventional to the labeling machine art may be employed for delivering adhesive to the picker plate 22.
Referring to Fig. 1, a shaft 45 supports a lever whose forward elongate arm 46 constitutes a guide on which slides a sleeve 41 (Figs. 1 and 9). 'Pivoted to this sleeve 41- at the point 48, so as to rock about a horizontal axis, is an arm 49 which supports the suction carrier 50 at its forward end. This suction carrier may be of conventional type customary in the labeling machine art, for example such as illustrated' in the patent to Holm 2,242,974, May 20, 1941, having suction openings in its lower face which communicate with an interior cavity which is connected, for example by a flexible tube ii, to a suction pump or other source of low pressure, (not shown) with an intervening control valve (notshown) such as common in the labeling machine art whereby suction is established and terminated at the proper intervals at the suction orifices in the carrier 5|. Preferably the arm 49 which supports the carrier to is so pivoted. for example by means of a jackknife joint J that it cannot swing downwardly below a predetermined position. A spring 52 may be arranged to urge the arm 49 downwardly. An actuating arm 53 is connected to the guide member 46, the actuating arm being provided with a cam follower roll 55 at its rear end which engages a cam 56 mounted on a driven shaft 51. A spring 54 holds the roll 55 in contact with the cam and at the same time urges the arm 46 in a clockwise direction such as to move the suction carrier 50 downwardly.
The sleeve 41, which slides on the guide 48. is connected by means of a link" to the upper end of a long lever arm 58 fulcrumed at 60 and having a cam follower roll 8| which engages a cam groove in a cam mounted on the shaft S.
As illustrated in Fig. 2, a jet nozzle 64 is arranged to deliver a jet of water. steam or other cleaning fluid against the exposed surface of the picker plate 22 mounted on the boss 20' of the shown in Fig. 2. A drip pan fl is arranged beneath the drum ll so as to collect the fluid which drips from the drum, the pan being provided with a drain pipe ll leading to a suitable delivery point.
In starting the machine it is desirable to rotate the drum is so. as to apply a primarycoating of adhesive to the picker plates, but without danger of applying adhesive to the suction carrier, before initiating the delivery of labels from the magazine. To this end a vertically movable rod 68 (Fig. 1) is arranged with its lower end directly above the rear end portion of the lever 53. The upper end of the rod BI is pivotally se-- cured to the rear arm 69 of a lever conveniently pivoted on the shaft W,-the lever having a forwardly extending arm provided at its forward end with a hinged or flexible extension 10 provided with a handle ll located conveniently for theoperator. A fixed detent I! (Fig. 7) carried by a part of the frame, may be engaged with the extension 10' when the handle is raised to its highest position, thus retaining the handle in this elevated position until the extension Illis manually released from the detent. Inorder to prevent advance of the magazine during this primary rotation of the drum, the lever 29 which controls the motions of the magazine is provided with a second arm l1 (Fig. 8) which is forked at its rear end and straddles the lower end of a vertical rod 19 having an enlargement is designed to engage the arm 11. The rod 19 is connected, as shown in Fig. 1. to the lever arm 10 at a convenient point. When the handle 'Ii is raised, the arm 11 is elevated, thus holding the magazine in elevated position until the handle II is again lowered.
When the handle H is elevated the rod 68 moves downwardly to depress the rear end of lever arm 53, thus holding the suction carrier in elevated position so that it cannot contact one of the picker plates. The drum may now be turned as many times as desired to insure a coating of adhesive on the several picker plates without danger of daubing the suction carrier and before any label is presented to the suction pickers. When the picker plates have received the initial coating of adhesive, the handle H is lowered and the normal cycle of operationbegins, this cycle being substantially as follows. It is assumed that labels have been placed in the magazine 23 and are normally retained therein by the customary means as above suggested. Assuming that the parts are in the position of Fig. 2, and that the surface of the picker plate 22 carried by the boss of the drum I 9 has received its initial coating of adhesive, the cam' II permits the spring 28 to move the magazine downwardly, thus contacting the lowermost label in the magazine with the sticky surface of the picker plate 22. The cam 3i thereupon immediately retracts the magazine, leaving this lower labelstuck to the picker plate. Thereupon the drum is is turned one-sixth of a revolution by the pawl Ill, thus moving the label to the transfer position, tha't is to say to the position of that picker plate 22 which is carried by the boss 20' of the drum, as shown in Fig. 2. Assuming that a label is on the picker plate, the label is brought to rest at the transfer position and as it comes to rest the suction carrier 50, which has previously been moved rearwardly by the action of the lever 59 is moved directly downward by the spring 54 (as permitted by the cam 56) so as to place the lower surface of the carrier I0 in contact with the exposed upper surface of the label. Suction is now established at the suction carrier such as to cause the label 'to adhere preferentially to the surface of the suction carrier. The am now moves the sleeve 41 forwardly in a path substantially parallel to the plane of the picker plate, thus sliding the label off of the picker plate and spreading the adhesive smoothly and uniformly over the label. This movement of the carrier continues until it is directly over the bottle 3 mounted on the rest 2, as shown in broken lines in Fig. 1. The cam It is so shaped that at this instant'the suction carrier is permitted to drop so as to place the adhesively coated surface of the label in contact with the bottle. The suction is now broken at the suction carrier by the action of the controlling valve, and the cam ll immediately lifts the suction carrier from the label and the arm as returns the suction carrier to its rearward position in readiness to descend upon the next label presented by the drum ll. As the drum continues to rotate step by step, the picker plate 22 from which the label has been removed at the transfer station arrives at the position 20 (Fig. 2) and is subjected to a cleansing spray from the nozzle 2'. After an idle stop at the. position 20, it moves to the position 20 where the picker plate is engaged by the roller 40 which swings back and forth across the surface of the picker plate at the position 20, thus applying a substantially uniform coating of adhesive to the exposed surface of the plate. At the next step the coated surface of the plate is registered with the magazine, thus completing the cycle of operations. After the label has been placed on the article 3, the presser 5 moves downwardly in the customary way so as to smooth out wrinkles and insure perfect adhesion, the operation of the presser being customary and well known. 7
While one desirable embodiment of the invention has herein been disclosed by way of example together with suggested .variations, it is to be understood that the invention is broadly inclusive of any and all changes and substitutions and rearrangements of parts such as fall within the scope of the appended claims.
