25 Claims.

This invention relates to machines for labeling bottles and other articles. Labeling machines in use today apply adhesive to the labels usually with a roller or with a spray. In the case of the roller adhesive applicator it is difllcult to apply the proper amount of adhesive without getting an excess which causes smearing of the container and frequently the roller applies adhesive principally to the side edges of the label leaving the center section with no adhesive. Furthermore, when labels are fed to rollers, the leading edge frequently is creased or folded and the label applied in that manner. With the spray-gun type of applicator there is a heavy concentration of "adhesive in the center part of the label and a light deposit at the edges where adhesion is extremely important. This type of applicator usually requires several heavy pressing operations to firmly fix the label.

One of the objects of my invention is the provision of' a labeling machine which overcomes the above objections and which is relatively simple in operation and which is extremely compactly arranged.

Another object of the invention is the provision of a machine the various parts of which are so synchronized for movement that it is impossible to cause any jamming of the apparatus.

A further object of the invention is the provision of an adhesive applicator which will supply an adequate amount of adhesive to each label without creating an excess thereof, and which will positively evenly distribute the adhesive and also apply it in such a way that the label will not curl.

A still further object of the invention is the provision of picker mechanism for handling the labels which will securely hold the labels while they are being moved and release them at the right time and which will also rapidly move labels between the label holder, the adhesive applicator and the container without lost motion and without requiring complicated mechanism for causing the movement of said picker mechanism.

Another object of the invention is the provision of a label holder which is so arranged that labels will be fed into picking position with automatic compensation for variations in the size of the stack of labels. I

These and other objects and advantages of the invention will more fully appear from the following description made in connection with the'acrompa-nying drawings, wherein like 7 reference characters refer to the same or similar parts plan view; Fig. 2 is a side elevation; Fig. 3 is an enlarged longitudinal .vertical section; Fig. 4 is an enlarged fragmentary detail of two of the operating cams with their cooperating levers; Fig. 5 is an enlarged detail of the mounting for one end of the adhesive applicator shaft; Fig. 6 is a section taken on the line 8-4 of Fig. 3; Fig. 7

is an enlarged fragmentary detail of one of the label holding elements and a portion of the label supporting table, and Fig. 8 is a detail view of an element of the picker means. I

The mechanism may be supported on a suitable frame composed of comer posts 8 and 9, upper side frame members I 0 and cross members ll, l2 and I3. Intermediate the upper and lower portions of the frame are horizontally disposed side elements H.

A label holder I5 is supported by a cross strip IS, an adhesive applicator I I is positioned adjacent the label holder and supported by a rotatably mounted shaft l8, and a container or other article support I! is located at the label applying station of the machine and is mounted on the upper end of a vertically adjustable rod 20. These elements will be explained in more detail below.

Picker mechanism The picker mechanism serves to transfer the labels from a supply stack to the label applying station of the machine, and in the illustrated example is used to transfer the labels from the label holder to the adhesive applicator and from the applicator to the container positioned on the container support. The picker mechanism, as shown, includes a tubular element 2|, one end of which is closed and secured by a hinge 22 to a rocking support 23, the latter being connected by a hinge 24 to the rear cross member l3. The other end of the picker tube 22 is bent downwardly at right angles, as shown in Figs. 2 and 3, and a rubber cup is secured thereto. The end of the tube is left open and the cup in its natural position is adapted to flare outwardly and downwardly a little below the end of the downwardly. turned portionof the picker tube 2| A branch tube 26 extends downwardly from throughout the views, and, in which Fig. l is a the main tube a' distance equal to that of the bent end of said tube, and this branch tube 26 is provided with a picker cup 21 constructed similarly to the left-hand picker cup 25. In the preferred arrangement, flexible members 25* and 21 are associatedwiththe picker cups 25 and 21 respectively in adjacent relation'thereto and so as to surround each of said picker cups as shown in Fig. 8. Rearwardly of the picker cup 21 is connected a hose 2! which extends from the tubular element M to the upper end of a cylinder 25, as best shown in Figs. 1 and 2. A piston rod 35 extends into the bottom of the cylinder 29 and carries a piston which is adapted to reciprocate in the cylinder to provide a suction pump. The cylinder 28 is closed to the atmosphere and its only opening is provided in connection with the tube 28. The lower end of the piston rod III is pivotally secured at ii to a lever 32 which extends upwardly therefrom and has its opposite end hingedly connected at 23 to the frame cross member II. This lever is best illustrated in Fig. 4. Intermediate the ends of the lever 22 is mounted a roller 24 which is adap d to ride against the edge of a cam 35, the latter being mounted for rotation with a power shaft 35. A spring 51 is connected between the lower end of the piston rod II and a suitable portion of the frame to normally urge the piston rod upwardly in the cylinder 29 and to hold the roller 24 against the cam 25.

The forward or left-hand portion of the picker tube 2| is ioumalled at 55 to a stub shaft 25. the opposite end of said shaft being connected to a crank arm 45 at one end thereof. The other end of the crank arm is secured upon a shaft 4| which also carries a gear 42. The gear 42 meshes with a gear segment 43 which is journalled at 44 and is connected by means of a lever 45 to a small crank arm 45, the latter being mounted for rotation with the power shaft 55. Rotation of the power shaft 25 will rotate the short crank arm 46 and oscillate the lever 45 and gear segment 43. The oscillatory motion of the gear segment 43 causes a similar oscillation of the gear 42, and this movement is transmitted through the crank arm 45 to the picker tube 2! with its picker elements 25 and 21 and flexible members 25' and 21'. In one extreme position of the picker elements the picker 21 and its flexible member 21* will be in contact with the uppermost label on the label holder l and the picker 25 and flexible member 25' will be in contact with the adhesive applicator i1, and in the other extreme position of the picker mechanism the picker elements will have rocked forwardly so that the picker element 21 will have deposited its label upon the adhesive applicator i1 and the picker element 25 will have moved a label from the applicator and deposited it on the container or other article held by the container or article support IS; in the last mentioned position of the picker elements 21 and 25 the flexible members 21 and 25 will coincidentally engage the applicator l1 and article respectively. The first position just described is shown in dotted lines in Fig. 3, and the second position is shown in full lines in Figs. 1 and 2. An intermediate position of the picker mechanism is shown in full lines in Fig. 3.

When the picker mechanism is being moved from the dotted line position in Fig. 3 to the full line position in Fig. 2, the cam 35 will be operated against the roller 34 to pull the piston rod 30 downwardly to produce suction in the cylinder 25, in the tube 28 and in the tubular element or hollow picker tube 2|. A label is placed preferably by hand upon the adhesive applicator to begin operation so that both of the cups 25 and 21 will be in contact with labels to prevent the loss of suction. The suction producing piston 30 is drawn downwardly throughout the movement of the picker mechanism over to the full I tion on the holder l5.

line position shown in Fig. 2. As soon as this last position is reached the high part 35' on the cam 35 will rotate past the roller 24 and continued rotation of the cam 35 will cause a sharp reversal of the piston rod 30 to suddenly relieve suction in the picker mechanism whereupon the labels will be released by the picker cups 25 and 21. It will be noted that the suction apparatus and picker mechanism are entirely closed except for the open picker cups. As the cups 25 and 21 respectively engage the labels, the respective flexible members 25' and 21' will likewise engage said labels.

Label holder The label holder i 5 is in the form of a flat table as shown, said table being supported by a rod 41 which is slidably mounted in a tube 48. This tube extends downwardly from a plate 49, the latter being supported by angle irons 50 which extend between the upper frame side members It. The rod 41 carries a U-shaped element 5| at its lower end, the latter having a roller 52 Joumalled therein and said roller being adapted to rest upon an angular lever 53 which extends into the U-shaped element 5!. The lever 53 is pivotally connected to a supporting strip 54 and said strip is in turn pivotally secured at its upper end to the stationary plate 49. As has been stated, the lever 53 is bent at an angle and an -adjustably positioned weight 55 is mounted ad- .iacent the lower end of said lever. When the plate holder i5 is pressed down, the weighted end of the lever 53 will swing upwardly. Therefore, when a relatively large stack of labels is placed on the holder i5, the weighted end of the lever will be nearer a horizontal position than when the table has approached its limit of upward movement. In this upward position there is less leverage exerted by the lever 53 for the reason that the weighted end thereof is closer to a downward vertical position.

Two pairs of label positioning fingers 56 and 51 are provided to hold the labels in proper posi- These fingers extend through slots 58 and 59 which are formed in the label holder IS. The fingers 55 extend upwardly from blocks 60, said blocks being slidable on a horizontally positioned rod 6| which is supported by the stationary plate 48. The blocks 55 are also in screwthreaded engagement respectively with opposite halves of a reversely threaded rod 52. The rod 52 is provided at one end with a crank 63 to permit rotation thereof with a rev suiting movement of the blocks 60 and the positioning arms 55 toward and away from each other as desired.

The positioning fingers 51 are mounted upon blocks 54 and bolts 55 extend through the lower portions of the positioning fingers 51, through said blocks 54 and are retained by suitable nuts 55 which are adapted to abut against the underside of the plate 49. Slots 51 in the latter permit sliding movement of the blocks 54 so that the positioning fingers 51 may be moved toward or away from each other. The first mentioned positioning fingers 55 are secured by bolts 56 to the blocks 50 which support them and all of the positioning fingers may be loosened at will so that they can be turned to different angles to accommodate different shapes of labels.

As best shown in Fig. 6, the positioning fingers are preferably semi-circular in cross section with their edges facing inwardly and the upper end of each positioning finger is provided with a pair of projections 88 between which are disposed a series of teeth 88. As best indicated in Fig. 7. when the label holder I8 moves a stack of labels upwardly, the uppermost label 18 will come up beneath the lower stop 88 on each of the positioning fingers. The teeth 89 and upper projections 88 are provided to separate the upper label from the one lying directly beneath it should the labels have a tendency to stick together.

Adhesive applicator A plate II is secured at one edge to the frame cross member II, and the opposite edge of the plate is bent upwardly to provide a supporting element 12. The support 12 has a pair of inwardly turned ears l8ifyhich are provided with notches I4 within which are supported the ends of a rod 15. This rod carries a plurality of thin sheet-like elements 18 which are preferably spaced slightly apart by washers which are placed between them. The flat portion of the plate II carries an adhesive container TI.

The shaft I8 has one end supported by a plate I8, said shaft lying in a notch I9 so that it is easily removable. The opposite end of the shaft is supported in a notched plate 88, and a pivoted catch 8I is provided to hold the shaft in proper position but to render it easily removable. This catch is best shown in Fig. 5.

Mounted'on the shaft I8 is the applicator element H, the latter comprising a plurality of spaced thin-plates arranged vertically and held apart by washer elements 82. At least the edges of the plates comprising the applicator I! are preferably rather thin and in Fig. 3 the configuration of the plates is clearly shown. A plurality of such plates disposed in spaced relation provide four concave label contact surfaces upon which the labels are deposited as each face of the applicator is brought to its upper position. The plates comprising the applicator are adapted to lie between the elements I8 which are supported by the rod I and the adhesive container I1 is so positioned relative to the applicator that the lower portion of each applicator plate will lie in the liquid adhesive. In Fig. 3 with the turning with its shaft I8 in a counterclockwise direction, those portions of the plates which have been immersed in the adhesive will pass between the staeach revolution of the power shaft 88 and power 'of sponge rubber.

wheel 88.

In Figs. 1 and 5 it will be noted that the applicator shaft I8 has a block 88 secured thereon. The block is four sided with its corners rounded or bevelled as desired. A relatively strong flat spring 89 is secured to one of the frame side members I8 and is adapted to bear against successive faces of the block 88 so that the Geneva gear plate 81 will be in proper position for the pin 85 to slip into one of the slots 88. Not only does the spring keep the Geneva movement in proper position, but it also acts to hold the applicator plates in proper position for receiving a label. The applicator and its shaft I8 as well as the wiper element are made easily removable so that after a labeling operation, has been completed the applicator and wiper can be easily detached to permit them to be cleaned. Cleaning of the applicator and wiper is important if the machine is to be left standing for any length of time to prevent adhesive from hardening bdtween the plates.

Presser The presser mechanism is used to press the label down on the container to which it is applied by the picker finger 25 and its flexible member 25' after adhesive has, been applied to the label by the applicator. The presser element itself includes a soft resilient pad 98 which is preferably The lower face of the pad may be flat or concave. A concave face is better for use with rounded containers. The resilient pad 98 is secured to a block 9| and the latter is supported by a bracket 92 which is adjustably secured on a vertically positioned rod 93. A thumb screw 92 is provided to permit easy ad- .iustment of the bracket 92 on said vertical rod. The rod 93 is slidably mounted in a sleeve 94 and a spring 93 is interposed between the top of the sleeve and the bracket 92 to normally urge the rod and the presser pad upwardly. A pin 95 extends from the rod 93 through a slot 98 in the tionary plates I8, the latter acting as wipers to remove most of the adhesive from between the applicator plates. This will leave a sufllcient quantity of adhesive on the edges of the plates but removes the excess from between them. It has been found that if the upper corners of the wiper plates terminate adjacent the corners of the applicator plates adjacent thereto, the wiping is more uniform than if the applicator plates had their comers extending above the uppermost comers of the wiper plates.

In Figs. 1 and 2 a wheel 83 is shown secured on the near end of the power shaft 88. The wheel 83 is provided with a crank 84, but, of course,

may be power driven if desired. A pin 85 extends toward the machine from the face of the wheel 83, and as the wheel is rotated the pin is adapted to slipinto one of the slots 88 in a substantially rectangular plate 81. The plate 81 is secured to the applicator shaft I8 and movement A of the applicator shaft in a step by step manner is provided. The wheel 83, pin 85 and slotted plate 8'! are constructed along the lines of the well known Geneva movement. This provides for 90 movement of the applicator shaft with sleeve 94. The pin not only limits the upward movement of the rod 93, but, also prevents it from twisting so that the presser pad will be maintained in its correct position. A pair of downwardly diverging arms 91 support the sleeve 94 and said arms are mounted on a shaft 98 which is mounted in suitable journals 99 on the intermediate frame portion I4. Thus the entire presser mechanism can be swung away from the container support .I 9.

. The lower end of the rod 93 extends below the sleeve 94 and is provided with an element I88 which carries a pair of spaced arms I8I. A lever 82 extends between the spaced arms vI8I and carries a roller I83 which is adapted to contact one or the other of the arms IN. The lever I82 extends rearwardly or to the right in Figs, 3 and 4, and is connected to a shaft I84, the latter being mounted in journals I85 which are secured to blocks I88, the latter being supported by the intermediate fram elements I4. The rearwardly extending portion I81 of the lever I88 is provided as a counterweight. Extending upwardly from the shaft I04 is a lever I88 shown in Fig. 4, the upper end of said lever carrying a roller I89 which is adapted to bear against the ered position of the shaft I02 and the presser are shown in dotted lines in Fig. 3.

A third cam III is mounted on the power shaft as as indicated in Fig. 3. This cam bears against a roller H2 which is mounted upon a lever 3, the upper end of which is hingedly secured to a convenient portion of the frame. The lower end of the lever H is pivotally connected to a lever III which is pivotally secured to one of the arms 91 which support, the sleeve 94 in which the presser rod reciprocates. when the cam I ii is rotated to push the levers H3 and ill to the left, the presser element will be swung to the left from its position above the container support M at the same time the presser is in its elevated position away from the container. A spring H5 normally maintains the presser mechanism in vertical position.

Container or other article support The details of the container or other article support are of no particular importance in view of the fact that the apparatus will probably be most conveniently used with a conveyor mechanism of any well-known type to bring containers into proper position relative to the adhesive applicator, the presser mechanism, and the picker mechanism. The support illustrated is merely a table I! held by a vertical rod 20 which is adjustably mounted in a base 20*. The support is adiustable for the reason that if containers of diflerent sizes or other articles of varying dimensions and shapes are labeled it is necessary to adjust the height of the container support to bring the label receiving portion of the container or other article to a proper receiving position relative to the other mechanism. As shown, the container or other article support i9 has a pair of side rails I I6 and one end stop Ill to properly position the container or other article. Such a container or other article support can be used if the containers or other articles are to be fed to the machine by hand.

Operation The operation of the machine is probably ap-- parent from the description above, but there are some points which should be carefully noted.

When the machine is first started, a supply of adhesive is placed in the container 11 and a stack of labels is placed in the label holder. One label is placed preferably by hand on the adhesive applicator and the power shaft is rotated to cause the picker mechanism to pick up a label from the label holder with the picker 2! and a label from the applicator with the picker 25. Because each of the suction pickers has a label thereon, of course, the suction produced by the piston and cylinder will be maintained. As the power shaft 38 rotates the picker mechanism carries over to deposit the label picked up from the applicator I! on the container or other article on the container or other article support and a label is also being transferred from the label holder to the applicator by the picker 21. As the labels are thus deposited respectively on the container or other article being labeled and the adhesive applicator, the flexible members 25 and 21' will engage the respective labels and will be caused to develop a pressure thereon to thereby press said labels into surface engagement with said container or other article and said adhesive applicator respectively as illustrated by solid lines in Fig. 8. The picker mechanism then moves toward the right to pick up another pair of labels and progress them, and as said picker.

aaaaaar ing portion of the adhesive applicator is presented to each succeeding label. Also during the movement of the picker mechanism toward the right and the movement ofthe applicator, the presser mechanism swings to a vertical position from the slanting position shown in Fig. 2, and

the presser pad or its equivalent is brought down to cause the label to be pressed firmly against the container or other article. Conversely as the picker mechanism moves to the left to deposit a label on the container or other article the presser mechanism swings to the left as in Fig. 2 so it will be out of the way of the left-hand picker element'25. In the description of the picker mechanism it was pointed out that just before the picker elements move from the dotted line position in Fig. 3 to the full line position in Fig. 2, the piston on the piston rod 30 will be drawn downwardly in the cylinder to apply suction to the labels to retain them on the picker elements 25 and 21, and as soon as the picker elements reach the position shown in Fig.

2, the cam controlling the operation of the piston in the cylinder-will cause the piston to be pushed upwardly sharply at least at the beginning of its upward stroke to suddenly relieve suction on the labels so they will be deposited by the picker elements. This sudden relief of the suction on the labels or in other words, the sudden change from negative to positive pressure in the pick up means insures efficient deposit of the label on the container or other articles and also avoids the possibility of disturbing the position of the label after it has been deposited on the applicator IT.

The method of applying adhesive to the labels is important. As has been pointed out above. the adhesive applicator is made up of a plurality of spaced plate-like elements which are relatively thin and the labels deposited on the applicator come into contact only with the adhesive which is on the edges of said plates. This deposits a plurality of lines of adhesive across the back of the label in spaced relation to each other, and when the label is deposited on a container and pressed thereon, the label will be connected to the container by a plurality of lines of adhesive and since the lines are spaced from each other the presser will squeeze all of the air from beneath the label along the spaces between the lines of adhesive. The air can readily escape because the lines do not intersect and because they extend to the edges of the label. The movement of air between the lines of adhesive, plus the fact that a very slight amount of air will, of course, remain, insures more rapid setting of the adhesive. The applicator guarantees a uniform supply of adhesive to each label and uniform distribution of adhesive on the back thereof. When the label is picked up from the applicator the surface tension of the-liquid adhesive will cause the lines of adhesive to form very slight ridges of adhesive material and when the label is pressed upon the container by the presser these slight ridges of adhesive will spread laterally into the spaces between said lines. Of course, the amount of space between the lines of adhesive can be determined by the spacing of the applicator plates.

It will, of course, be understood that various changes may be made in the form, details, arrang'ement and proportions of the various parts without departing from the scope of the invention.
