11 Claims.

This invention pertains to labeling machines and more especially to novel wiper mechanism for pressing and affixing a label previously gummed and engaged with the article to be labeled into firm contact with said article. More particularly it concerns wiping and pressing means operative simultaneously to affix a body label, a shoulder label and a neck label to a bottle. In its broader aspects the invention contemplates the employment of mechanism capable of simul taneously affixing body labels, shoulder labels and neck labels to diametrically opposite sides, respectively, of a bottle.

In machines of the straightaway type (a machine of this general type being shown merely by Way of example in the patent to Holm No. 2,026,172, dated December 31, 1935), the article to be labeled hereinafter referred to as a bottle is moved intermittently by a conveyor along a substantially straight path, dwelling at each of a plurality of stations at which various operations involved in the label application are performed; for instance at one station the gummed label is engaged with the bottle by a picker device and at a later station a wiper or presser applies pressure to the entire area of the label, smoothing it and causing its entire area to adhere to the bottle. When labels are to be a plied to diametrically opposite sides of the bottle the wiping station is provided with wiper and presser elements located at opposite sides of the conveyor path and with means for simultaneously actuating both sets of wiper and presser elements.

It is not particularly difiicult to apply a label to the body or neck of a bottle of usual type (these portions of the bottle usually being approximately cylindrical) but it is not so easy to apply a label to the shoulder portion of a bottle which is of a curvature approaching the spherical, so that a wiper, moving in a horizontal path (perpendicular to the axis of the bottle) cannot apply force in a direction normal to the surface of the shoulder as is requisite for adequate afiixation of the label.

Among the objects of the present invention is to provide label-wiping and pressing mechanism, readily applicable to existing straightaway machines of commercial type, capable of wiping body, shoulder and neck labels all at the same time while the bottle dwells at the wiping station. A further object is to provide wiping and pressing mechanism capable of duplication at opposite sides of the conveyor path, if it be desired to apply body, shoulder and neck labels at opposite sides of the same bottle. A further object is to provide wiping and pressing means so designed as to permit disconnection and removal of one or more of the wiper devices without affecting the operation of those remaining if, in a given case, less than three labels are to be applied at once.

A further object is to provide wiper and presser means of simple yet reliable type capable of applying wiping pressure of all requisite intensity and uniformity, and which is adequate to wipe shoulder labels as well as body and neck labels. A further object is to provide wiping and pressing means which is adjustable for use with articles of diiierent sizes. 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. 1 is a diagrammatic plan view, to small scale, of a straightaway machine of the type to which the present invention more particularly relates, showing two sets of wipers in accordance with the present invention arranged at opposite sides respectively of the conveyor path;

Fig. 12 is a side elevation of a rocker for supporting the shoulder label wiper.

Referring to the drawings, the numeral l designates the frame of a straightaway labeling machine of a generally conventional type. The articles to be labeled, hereinafter referred to as bottles, are advanced intermittently along rectilinear guide rails 2 (Figs. 1 and 3) between guard rails 3 by a feed member F (Fig. 3) dwelling for a suitable interval of time at at spotting station 4, then at the labeling station 5 and then at the wiping station 6, after which they continue along the guide rails to a delivery point. In machines of this type it is customary first to bring the gummed label into adhering contact with the article by means of a picker or the like at the labeling station, and then, at

the wiping station, to apply wiping pressure to the label so as to smooth it and firmly affix it to the article. As illustrated in Fig. 1, such a machine may be arranged to apply labels simultaneously to diametricall'y opposite sides of the slides. Thus, as illustrated in Fig. 3, thefraine I of the inachin'e comprises the usual table I from which bearing brackets 8 depend. The longitudinally eaten'ding' drive Shaft 9 is mounted in these brackets, being driven by usual means (not shown). The machine shown is of the duplex type (designed to apply labels to either or both side or a bottle) and 'tw'o like cams I I] and H are fixed to this shaft to operate the opposed wiper slides. I

Brackets l2 and I 3, fixed to the underside of the table 1 at opposite sides provide pivotal supports for levers comprising the lower arms l4 arid respectively carrying cam follower rolls l6 and IT respectively, which engage the cams I0 and. Il. These le'ver's also comprise the upwardly directed arms [8 and I9 respectively, which extend up through slots in the table and which are ccnn'ected by links and 21 to the wiper slides 22 and 23 respectively. These slides are guided for reciprocating motion in a horiaontalplane in guide'w'ays 24 and 25 respectively, formed in rigid stands 26 and 21 respectively inounted on the table I. If, in any instance, duplicate or triplicate wipers are to be provided at time or both sides at the wiping station, there will be a corresponding number (if stands 26 and 2'! carrying corresponding wiper slides and mechanism actuated thereby. V

As thus far described, the machine is designed for actuating wipers at diametrically opposite sides of the bbttle, but since the wiping mechahisms at opposite sides of the tracks 2 are duplicates, it suffices hereinafter to describe but one ofthese mechanisms in detail.

Referring to Figs. 3 to 5 and "7 to 9, the numeral 28 designates a rigid upright support, here shown as a casting, comprising a base portion29 which is provided with a vertical slot (defined by the gibs at) (Fig. 10 which receives (with a snug, sliding fit) a rectangular head 31 (Figs.

7 and 10 at the inner the or the slide 22. The upper end of this head 3| underlies a lug 29 at the upper end of the s1tt so that when the support 28 is fitted onto the head 3|, the subpcrt is firmly held in position and supported by the 4 slide. This provides a very rigid but readily disconnectable union between the slide and. support.

The support 28 is preferably shaped as shown in Fig. 9, so as to reduce weight, having the laterally spaced leg portions 32 integrally connected at their upper ends to the table 33 and at their lower ends to the base 29, and united at an intermediate point by the web 34. An ear projects from the outer side of the web 34 and a rigid brace leg 35 (Figs. 3 and 4) connects this ear with a bolt 31 projecting from the side of the slide 22. Thus the support 28 is so securely connected to the slide that it is capable of exerting very substantial pressure against the bottle (through the wiper pads hereinafter described) without any pcs'sibility of yield.

The table portion 33 of the support 28 has a horizontal upper surface on which is removably mounted a block 38 (Fig.- 5) having a guide channel in its upper surface which receives the auxiliary 6r neck wiper slide 39, this auxiliary slide being confined b gits 40 and beingurged 1m wardly or toward the article to be labeled by a tension spring 41. The slide 39 is bifurcated (Fig. 6} at its inner end to provide the curved arms 42 and 43 which support conventional neck wiper means, here shown as including a yield= able pad 45, for example, of sponge rubber, supported by bell crank levers, one of which is ind1= cated at 44. This has 45 is operat ve partially to embrace the neck portion N of the bottle in conventional manner so as towip'e the adhesively coated end portions of the label firnily about the neck. As illustrated in Figs. 4 and 6 the machine is set up to apply a label to one side only of the bottle neck, the pad 45 extending more than 180 about the neck. To prevent the bottle from tipping in re ponse to pressure of the neck-wiping pad, an abutment element 46, which may be a pad of hard rubber or the like, is arranged to engage the neck N diametrically opposite to the wiper 45, This abutment as may be mounted on a slide 4"! corresponding to the slide 39 and sup-- ported and actuated in the same way. If the neck of the bottle is to receive labels at diametrically opposite sides, then the wiper pads, such as the pad 45, must be of such dimensions circumferentially that the pads at opposite sides do not interferejwith each other.

The support 28 (Figs. 4, 5 andQ) is provided at opposite sides near its base with parallel, h'o'riaontal bores 48 and 43. In each of these bores a rigid stud 50 (Fi 4) is arranged to slide. Each stud is provided with an axial bore extending inwardly from its outer end and has an elongate slot 5| near its outer end which receives a limiting pin 52 fijged to the support 28. A compression spring 53 within the tenth bore in the stud bears at its outer end against an abutment sleeve 54 within the bore in the stud and which engages the pin '52, the springs urging the studs 50 outwardly or to the left (Fig. 4). The studs 50 project to the left or the support 28 and to their left=hand ends a body wiper frame 55 (Figs. 4 and 11 is rigidly bolted. Tc this body wiper frame the wiper Wings 56 and 5'! (Fig. '6) are hinged. These wiper Wings support the body label Wiper pad '58 in'conventional inanner. This pad is of resilient material such as sponge rubber and is designed 'to press the adhesi'v'ely coated end porticns of the label against the body portion B of the bottle. v

The frame 55 is provided with spaced, upstanding lugs 59 and 50 (Fig. 11) between which is arran ed the lower arm 6| (Fig. 12) of a rocker which carries the shoulder wiping pad. This rocker is here shown as L-shaped, having its arm 6| pivoted between the lugs 59 and 60 on a pin 62 (Fig. 4). This rocker has a second arm 63 which carries the shoulder wiper pad 6 1, of yieldable material such as sponge rubber and of conventional shape for pressing the entire label into contact with the shoulder S of the bottle. The angle 65 of this L-shaped rocker is pivotally connected to the inner end of an extensible link comprising relatively adjustable parts 66 and 67 (Fig. 4). The part 6! has a saddle portion 68 at its outer end which normally straddles a stud 69 (Fig. '7) which connects the link 20 with the slide 22. A set screw (Fig. 4) normally keeps the saddle from lifting from the stud. By rela-- tive adjustment of the parts 66 and 61 the effective length of the connecting link may be varied, thus varying the pressure which will be exerted by the pad 64 against the shoulder label.

In the operation of the machine the cam iii moves the slide 22 outwardly, as the feed member F (Fig. 3) advances the bottle into the wiping station 6. As the bottle comes to rest, the slide 22 moves inwardly or to the left (Fig. 4) carrying the support 28 and the body wiper frame 58 toward the body of the bottle. When the body wiping pad 58 contacts the bottle, the inward motion of the frame 55 is thereby terminated, but the slide 22 and support 28 continue to move inwardly, as permitted by the yielding of the springs 53, and the link 68, $1 swings the lever arm 63 counterclockwise, thus pressing the pad E l against the shoulder label. During the inward motion of the Support the auxiliary or n wiper slide 39 is moved toward the bottle, eventually bringing the pad 45 into wiping contact with the neck label, the spring 4! yielding to prevent undue pressure. When the wiping action is completed, the slide 22 moves outwardly and the several wiper pads are returned to the initial inoperative position.

With the above arrangement it is possible to wipe a body label, a neck label and a shoulder label simultaneously and with assurance of proer shoulder presser pad is moved in an arcuate path whose terminal portion, at least, is normal to the shoulder surface of the bottle, so that the labelcontacting face of the pad is positioned to apply direct, normal pressure to that surface of the bottle against which the label is to be pressed. It is further obvious that the shoulder wiping pad will be shaped, in accordance with the more or less spherical contour of the shoulder portion of the bottle, so as to insure a uniform smoothing action upon the shoulder label.

it is also evident that if it is not desired to apply the shoulder label, in any given case, the link @6, 5? may be disconnected, for example, merely by lifting its saddle portion from the stud 69, so that the rocker carrying the shoulder label pad will not be swung toward the bottle. It is likewise obvious that if the neck label is to be dispensed with, the slide 38 may be removed, together with the neck Wiper pad, without disturbing the operation of the body and shoulder wiping devices.

One desirable embodiment of the invention has been illustrated herein by way of example, but it is to be understood that the invention is broadly inclusive of any and all modifications falling within the scope of the appended claims. I
