APPLYING MACHINES Filed Feb. 1l, 1953 ATTORNEYS United States Patent Giltice 2,720,995 Patented Oct. 18, 1955 2,120,995 LABEL APPLYNGMACHINES George W. von Hofe, Bound Brook, N., 1;, assignor to New Jersey Machine Corporation, Hoboken, N. J., a corporation of New Jersey Application February 11, 1953,.Serial No. 336,261 11 Claims. (Cl. 216-55) This invention relates to label.applyingV machines and particularly to that classof labelingmachines in which the labels are fed from a source of supply to a label applying station aty which they are placed upon articles-and then subjectedto the action of a-pressltrtv device to com.- plete their application to the articles.

An object of the invention is to provide an improved labeling mechanism capable of reducing the. period of label application to enable an increase in Athe feeding time 'of the labels without slowing down the machine or to enable a substantial increase inthe productionA of the machine without reducing thefeeding time of thelabels.

Another object ofthe invention is to provide an im.- proved labeling mechanism capable of removing entrapped air from under the label during the application of pressure to the latter so as to secure perfect adhesion of the label to the article.

A further object of the invention-isV tofprovide an improved labeling mechanism capable of applying pressure to the label immediately after it has'been placed'on the article.

A still further object of the invention is to provide an improved labeling mechanism capable of applying a high pressure to the label without increasing: the. power` used in the machine and withoutapplying high forces to the article being labeled.

Other objectsvand advantages of theinvention, aswell as the novel features thereof will appear fromY a perusal of the following description when read in connection with the accompanying drawingsin which Fig. 1 is a fragmentary side elevational View. of a label applying machine embodying. the invention, and

Fig. 2 is a front elevational view. of some of the parts shown in Fig. l.

In the following des criptonthe useof the termv labeP7 is intended to include any sheet of material which is to be deposited on an article for the purpose of identifying the contents thereof, or for any other purpose. The label may have any desired form and. mayY have thereon any suitable type of adhesive material for adhering it to the article. Also the labels may be fed from a. continuous web or from a supply of individual labels, as is well known in the art. in accordancev with. the. invention, the labelsV are fed from the source of; label supply to the article support itl byl means of a pickfup device. of the suction'operated type which` is designated. generally in the drawings by theV numeral 11. After a4 label has been deposited upon the article 1,2.- positioned. on Support-.19, pressure mechanism designated generally by the. reference numeral 13 comesY into operation to.V complete the adhesive application of the. label toA the article. In gen,- eral the machine in which the aforesaid devicesare. ern.- bodied may be of any well-known type, but modified in accordance with the present invention. For the purposes of illustrating the invention,l suchv devices, have been shown as embodied in a labeling',machine, such as. is described and illustrated in the von. Hofe Patentv No. 2,227,816 issued January 7, 1941.. In such ag. machine there.. is provided a carriage. 14 (see Fig. l) slidably mounted on a horizontal guide rail 15 supported on the frame of the machine. Thev carriage 14 is reciprocated lengthwise, of the rail 15 in predetermined timed. sequence by mechanism exemplified in Fig. 1 of the drawings by the rod 16` which is pivotally connected at 17 to the carriage. A memebn or plungerV 18.. is slidably mounted on the carriage 14and is vertically reciprocated thereon in properly timed relation with the associated parts by mechanism eXemplied inFig. 1 of the drawings by the roller 19 which is adapted to travel along a horizontally extending-track 20 arranged to be raised and lowered to reciprocateV the member 18. The downward movement of the member 18 may be facilitated by a vertically disposed spring 21 which isl connected at lits lower end to thefcarriage 14 and at its upper endto a lug. 22: on the member 18. Secured to the lowerfendof the member 18 through-ayoke 33. is the label carrier or transporting device 11'.

ltwill; be understood fromthe partsV of the labeling machine thus far described, that when in the operation of the machine, the partsv are positioned as shown in Eig; 1;, a labell 23 has just been deposited by the carrier 11: upongthe article 12 andthe track 20 has been raised to lift-,thermemberf 18 and consequently the label carrier 11 away fromthe article. The label carrier 11 is of the suetiontype and isconnected by tube 34 with a convenientt source. ofv suction which is controlled by properly timed valving-means of any suitable typel so that suction isfetfectedlat thelabelcatrrying surface 24'of such device, while'tis picking up a label from the source of label supply andluntil the,v label carried thereby has been deposited on the article 12. ln the position of the label carrier: 11 Vshown in Eig. 1;. of the-drawings,vthe suction theretohas been eut off by such valving means. From its position-inlFig. l of the drawings, the label carrier 11 is retracted bythe carriage. 14 which is caused to move to theV right, as viewed in Fig. l of the drawings. When the carriage V1,41 reaches the'r-ightahand limit of its movement alongthe. rail 1K5', the label carrier 11 will be located above and in registry with the next label at the source of label supply, to be deliveredV to a succeeding article to begltgtbeled.` The movable rail A2() will. then be lowered totenable, the` labelcarrier. 11.- to pick upy such label. At thistitne suction is again elected at the label supporting surface24fof the carrier A11. When a label 23 has been pic-lied up by the carrier 11, the track 20 is again raised to elevate. theA member 18 and consequently the label carrier 1,1. The carriage'14-is then caused to move to-the left, asviewed in Fig. 1 of the drawings to-bring the label car-rien 11 over the articie12 mounted on the support 1l) in` label receiving position. The track is then again lowered andztheirnember 18 moves downwardly on the carriage 14 thereby causing the label carrier 11 to deposit. the label 23- carried thereby upon the article 12. To. enable this tobe accomplished, the valving means operatesto discontinue the suction inthe label carrier 1,-1.. When the disposition of the label has been completed, the label carrier llis lifted by the action of track 2Q on the roller: 1 9 and member 18, thus bringing these parts bach to the positions shown in Fig. l of the drawings., to` repeat they operations above described.

After the. deposition of, a label 23; on the article 12, a roliler 25; of the-pressing mechanism 13V is lowered to the dotted linepositionshown in Fig. 1 of the drawings, to enable, it to press the labely onto the article 12 as the carringe li-retracts the label carrier 11 to the label supply station. to. receive a new label in thev manner above de.- scribed. As shown in the drawings, the roller 25 is ro,- tatably mountedon a shaft 26 supported at its ends on the offset,` downwardly extending end portions of a pair of spacedV arms 27, 27'. The other ends of arm 27, 27; are

During the continued advancing movement (of car- -rierV 11, the Vrollers 35, 35, will roll across the plate 36-with the roller 25 in a substantially fully raised position.` At the end of the advancing movement of carrier 11, it is lowered and raised bythe track 20 in the mannerA previously explained to deposit the label carried thereby Yupon lthe article* 12, and to bring it to a position to be longitudinally retracted by the carriage 14 on the return movement of the latter. This point in the operation of the pars is illustrated in full lines in Fig. 1 of the drawings. When 'the vcarriage 14 `starts its return mcvemenbto the right 'along theirail 15 to" retract the label carrier 11 to the .label supply station, the lever 41 will be rocked downwardly on. its `shaft to shift the plunger 39 downwardly. This' causes the shoe 37 and plate 36 to move downwardly,

the latter through the rollers 35, 35, causing the arms 27 27, to be rocked downwardly about the axis of shafts 28, 28, to bring the roller- 25 down to the dotted line position shown in Fig. 1. The rocking of lever 41 is so timed that the roller 25 is in its lowermost position immediately after the carrier 11 has started its return movement, and before the carrier 11 has been retracted'suiciently to bring roller 25 over the portion of the bottle to which the label has Ybeen,applied.- As the carrier 11 continues its retracting movement, .the-lever, plunger 39 and Vroller 25 are maintained in their lowered positions, the roller 25 rolling upon the label Ato irnit tq the surface of the article 12. During the progressive'advancement of the roller 25 over the label, its force willbe applied along a line contact, thereby subjecting the label tov a substantially greater ironing pressure than could be applied by a pressure plate using the `same force. Thisprogressive application of force also accomplishessqegeeaction t'yrr'einoye any entrapped Yairftfr'eiri b'etwe'nthef label andfie article, and thereby avoids'the possibility f blisti'sfkfrfringlunder the label.
