FREDSELL LABELING IACHINE Filed Sept. 12. 1930 3 Shets-Sheet 3 Patented Aug. 30, 1932 UNITED STATES PATENT OFFICE CHARLES RAGNAR FREDSELL, OF NEW YORK, N. Y., ASSIGNOR TO IODONALD EI- GINEERING CORPORATION, OF BROOKLYN, NEW YORK, A CORPORATION 01 m YORK LABELING MACHINE Application filed September 12, 1930. Serial 80.181315.

This invention relates to labeling machines, and-has to do more particularly with the taking of a label from the magazine, applying adhesive thereto and aflixing the same to the article at the same station.

I have shown my invention as may be applied to any labeling machine, but particular reference may be had to Patent No. 1,743,018 granted to Magnusson and Fredsell, showing a type of machine to which my improvement is applicable.

While I am able to dispense with any supplemental adhesive applying means at a prior work station and perform-the entire work of applying adhesive at one station, v1z the magazine station, I do not wish to limit my invention to a single work station and have therefore shown both methods of operation.

In labeling machines, it is the usual practice to reciprocate work slides to and from the articles to be labeled, while said articles are intermittently passed along on a suitable support, to successive work stations, where first, at one station, the full area or a portion only of the article is supplied with adhesive, and then passed to the next station, where a label is removed from the magazine and attached to the article by adhering thereto, and finally at another station the m label is pressed to the article. By this method it must be conceded, it is diflicult to apply allthe adhesive to the article 'so accurately that the label will register precisely with the adhesive of the article thus supplied, and further if the article is round or of oval shape, the contact made therewith by the label is not suflicient to properly cling to the article to remove the label from the magazine, as the latter withdraws from the article.

It is an object therefore of this invention to provide means whereby substantially the full face of the label may be supplied with adhesive at one and the same station at which the label is removed from the magazine, and I attached to the article, or when applying only a fractional part of the adhesive to the article as done at a prior station by using a flexible adhesive pad, adapted to yield and thereby cover a greater area of surface of t the article so as to conform to cylindrical or oval shapes thereof and when engaging the central part of the label, at the next station, 4 the magazine station, to afiix the label to th' article, and at the same time apply adhesiv to the remaining ends of the label by a two part adhesive pad that straddles thearticle by a direct forward line action, and by either during its motion to and away from the article, to pass the article and close around the same so that the pads will deliver adhesive to the full or substantially full face of the label, located inthe same plane and carriedby a magazine movable to and from intfront thereof, whereby the partial application of adhesive to the articleat a prior station may be omitted. 7

Another object is to provide a means to bring the article to a vertically aligned position with respect to the label stack before and during the time the pads return with the label from the magazine to apply the label to the article. 1 Other objects will a. ar in the followin detailed description an more fully referred to in connection with the drawings. Before explaining in detail the present im-.

provements and mode of operation thereof, I desire to have it understood that the invention is not limited to details of construction andarrangement of parts, which are illustrated in the accompanyin drawings, and that the phraseology which I employ is for the purpose of description and not of limitation. 4

Figure 12 is a view of the article showing a label attached.

While the drawings show only a portion of the labeling machine, it is deemed unnecessary to show other than the magazine and its co-acting mechanism, to which this invention particularly relates.

As shown, the table 10 and frame-work F are provided and fitted with work slides 12, 13, 14 and 15, each of which have certain functions to perform by suitable work members carried thereby, on the articles that are moved along step by step between the slides on a supporting conveyor belt 16, arranged to have working in unison therewith a holder belt 17, that firmly holds the articles under tension between these belt surfaces to accurately deliver the articles at their respective stations.

The slides as shown in Figure 1, due to the small articles on which the work is to be per formed, are arranged to work on two articles at one time, at each station. This however is not essential, as a single work member may be used on single articles of larger proportion.

At the station where the slide 12 is positioned, it is the usual practice, particularly when the article is of a rectangular form, to apply adhesive to one face of the article by a contact pad, the face of which is usually a fraction smaller than the face of the label to be attached, or the adhesive pad may be of the sectional form to fold around the box shaped article when the label, of course, will be longer to fold around the sides. In the present instance however, the artlcles designated by A, shown as bottles of cylindrical formation, are acted upon by flexible adhesive pads 12 and 12 preferably of rubber strips that revert to a fiat plane position at all times, except when in contact with the article, at which time the pads will be depressed so that the face thereof will conform to a greater portion of the curved face of the article. (See Figure 1 and Figure 4.) This will supply a fractional part of the adhesive to the article. The slide 12, it will be noted, is of such proportions as to accommodate two flexible pad members, side by side, held by brackets 12 and 12, adjustably fixed to an angle bracket 12 when the pads are in the position as in Figure 1, an adhesive supply roll 12 is actuated to roll over the face of the pads to supply. adhesive thereto.

To support these flexible pads in their fiat plane position during this adhesive applying action, spring plungers 12 are provided that rest against the rear of the pads to positively bring them to this position. The plungers have a head 12, of suitable diameter to provide a proper backing against the back of the pads, and are held in this forward position by a spring 12 against adjustable stop collars 12, the plungers sliding in bearings 12". The supply roll then returns to permit the slide to move forward and make contact with the article to apply the adhesive. When the articles are small, as before stated, I prefer to use two pads mounted on one slide to double up the production of the machine, but usually on larger work one slide carries a single work member. slides l3, l4 and 15 which will be hereinafter referred to.

The movable support 16 is then actuated to move two articles forward to the next work station, where the labels designated by L will be supplied by a pair of label magazines 21 and 22, carried by the reciprocating slide 13 which is carried forward so the labels will contact with the articles and deposit the labels thereon.

It will be here seen that the end portions L and L of the labels L, which will thereafter lap around the articles to encircle the same or nearly so, as the case may be, have yet to be supplied with adhesive. A pair of supplemental adhesive applying members are provided for this purpose and are shown in the form of two part adhesive pads 2824, carried by the slide 14 to be reciprocated in a plane with the aforesaid magazines on the slide 13 and timed to move toward and away from each other. These two-part pads are shown preferably made in two sections, 23 23 and 24 24 each adjustably fixed to a bracket 2525 attached to the slide 14, so that a true register with the position of the labels carried by the slide 13 may be had.

This is also to be understood of the tact with the'foremost labels of the magazines and apply adhesive to the ends L and L thereof, as the labels are brought to contact with the articles b the forward movement of the slide 13. he ma azine slide 13 moves a small distance furt er than just making contact with the article and depresses the stacks of labels rearward in the-magazine box and away from the overhanging stops 30 at the sides 31 of the magazine, and free from the edges of the labels as clearly shown in Figure 6. This position of the stack of labels is held during the retracting motion of the pads on slide 14 and holds thelabel intact with the article while the pads are pulling the ends of the labels L and L free from the stops, separating the labels to assure the taking of but one label from the stack. This operation is aided by the flexibilityv of the labels while being attached to the curved form of the article at its center, and further drawn around and against the article by the continued retracting motion of the pads. The stack of labels now resumes its position in the magazine box against the stops, as both slides return to their outer positions, the pads at this point are given a fresh coat of adhesive.

The magazines are mounted on a plate 35 carried on the slide 13, and this plate which forms the base on which the labels rest, and to which the side plates 31 of angle pieces are fastened by screw 37 in slotted holes, so the side plates may be adjusted to bring the labels into perfect alignment with the adhesive pads and central with the articles.

The stops 30 are arranged on the side members 31 in pairs to provide two on each side,

' one above the other so as to provide a stop at each corner of the labels, these stops may overhang the label to a greater extent than is usually done, because of the backing up of the labels when the contact with the article is made, at which time it will be seen the two part pads reach into the magazine, see Figure 5, there being cut outs in the pads, as at 38, which pass the stops 30 when applying the adhesive to the labels.

A movable overhanging support 39 of the magazine, which forms an extension of the base plate 35 and is flush therewith for the labels to rest on, and arranged to slide forward against a stop, and is under a spring pressure as to extend a small distance for; ward of the stack of labels to support the foremost labels from dropping; this support is pressed rearward when the labels are in contact with the articles. Each magazine is provided with a plunger head 40 mounted on a rod 41 that slides in bearings 42and urged forward by a spring 43 to keep the stacks of labels feed- 1 ing forward to the stops, the rods beingsquare to prevent rotation of the heads which are fast to the ends of the rods. The springs 43 are fixed at one end to the forward bearing as at 43 and the other ends to a pin 41 on the extreme and of the rods 41. A swinging cover piece 44 is also provided for each magazine, andis here shown as a bar pivoted as at 44 to the rear of the magazine to uprights 44 adapted to be swungback when filling the magazine, and these bars further serve to hold the labels down on the base. A means is also provided to prevent the magazine slide from making its full forward stroke when an article is missing in front thereof, the movable sup- 1 port may fail for some reason to feed the articles to this work position, a stop piece 50 is provided and fitted to the underside of the slide 13-see Figures 1, 2 and 3a, and movable therewith, which stop co-acts with a spring pressed arm 51 normally in the path of.the stop, but held out of the path thereof by a cam arm 52, shifted by a two armed rock member 53, pivoted at 54, the movement of which is controlled by an article on the support as the article is being moved to its work station.

is actuated by a cam (not shown) to move the slide outward or away from the article but moved inward to follow the cam by a spring 55 to force the slide inward and hold the cam levers to the cam, except when this stop 50 is engaged by the arm 51 which will hold the slide against its further movement.

When the labels have thus been applied to the articles, the movable support carries the articles forward to the next work station where the slide 15 is positioned. See Figure 1 which is likewise reciprocated to and from the article and carries a pair of work members to firmly press and smooth the loosely attached labels down. These members as shown are preferably under a spring pressure, and include in their make up, a center block 60 of rubber or other suitable material, the face of which may be fitted to conform to the shape of the article at the point of contact, and

these blocks are mounted on heads 61 fast on squared rods 62 to prevent rotation thereof .and sliding in bearings 636 t fast to the carprovided with ears 63 to which swinging arms 66 are pivoted; having rollers 67 on the ends thereof the-arms are held together in any rods, while the slide continues forward, carrying the arms forward therewith, as a result the swinging arms will spread, and the rollers follow the contour of the articles, and thereby press and smooth the labels firmly to the articles. As the articles are moved from station to station on the supporting belt 16 and top belt 17 which is employed to hold the articles in position under a tension against shifting during the moving of the belts, is not sufficient however, to hold the articles against the work members while the articles are at rest at these stations. Therefore, stationary supporting members are provided which form rests placed in such position to support the articles against the work members as the latter contact therewith and thereby prevent displacement on the belt. These supports are indicated at S. and are in the form of depending arms held in place on a top rail T., the latter being a part of the frame work F.

In Figures 8 and 9 another form of the two part pads is shown, in which the pads 7 0-7 1 are carried on rock members 72-73 pivoted on adjustable arms 74, located on the slide 14 as will be remembered, the stationary bifurcated brackets 25 and 25 of Fig. 1 have a spread to clear the article, as these pads carried thereby move toward the labels of the magazine mounted on the slide 13, making it necessary to first apply adhesive to such an amount to the article at the prior work station at the position of the slide 12 to cover this part of the article with adhesive to coin cide with the spread of the pads. In this form, now being described however, it is possible to apply adhesive substantially to the entire face of the label, omitting if desired the use of the work station where a partial amount of adhesive is first applied to the article; this depending of course on the article to be-labeled, since many forms of articles are adapted to my improvement whereby it may be more convenient to use both stations to apply adhesive, but this mechanism now being described and located at the magazine station, all the adhesive supplied to the label is done at this station.

The slide 14 is reciprocated by a rock arm 75 mounted on a rock shaft 76, the arm connecting the slide at 14 by a link connection 14 The rock shaft 75 is rocked by a suitable cam (not shown) which controls the movement of the slide in timed relation to the label magazine carrying slide 13 The arms 7273 that carry the pads and 71 are controlled in such a manner, to be in a flat plan position, as shown in full lines, in Figure 8. When the slide 14 is full retracted to a position of rest to receive a hesive at this position from a su ply roll 79, the roll receiving a supply of ad esive from a supply means as at 80, Figure 9, then traverse'the face of the pads to appl the adhesive thereto, which is then transfirred to the label of the magazine, after the pads have received the supply of adhesive and the supply roll clear of the forward motion of the slide, the latter starts forward the rock arms 72-73 are swung on their pivots 75 by links 81 pivoted to cam arms 82 that are pivoted at 83 on adjustable brackets 84 on the slide whereby the pivots 83 and the aforesaid pivots 75 reciprocate with the slide.

Fixed to the frame F but adjustably mounted for different size articles, I provide oppositely disposed cams 85 and 86 which have cam faces 85 and 86 of any desired formation to rock the arms 82 by engaging rolls 87 and 88 on the arms located at the ends thereof, and opposite to the end carrying the links 81 with the pivots 83 on which they rock approximately midway thereof. The rolls 8788 are urged against the cam faces by a spring 89 attached as at 90 to the two arms, so the levers 82 will be rocked to provide the movement to shift the picker plate pads 70 and 71 to clear the article and swing to their flat plan positioned to engage the foremost label and apply adhesive thereto. See dotted line contact position with the label Figure 8, also Figure 10 shows a diagram on the left hand side thereof, by which I have indicated the action of one of a pair of picker plates as 70, the other plate 71 being the same, only the action of this one side being described, as noted in this diagram the picker plate 70 when the slide carrying the supports 74 and 84 are at the point a and a is shown at rest and in its flat plan position, at which time the adhesive is applied, at the points I), 0, d, e and f, and b, 0 (Z 6 and P, the several angular positions of the picker plate is indicated in broken lines showing how the plate is swung to clear the article A and again revert to a fiat plan position as at G and G to make contact with the label as in Figure 8. In this diagram on the right hand side thereof is shown an example of a smaller article A the' article is positioned forward on the support,'to present the front face therefore to the magazine labels, so no adjustment need be made to the magazine, except to change the side walls thereof for a shorter label. A suitable cam 86 is positioned on the frame F to provide a motion as indicated by the dotted line of the picker plate 71 as will be readily understood.

It has been found that articles, especially bottles the bases of which are not always square with the sides thereof, and would therefore not stand in a. perfectly vertical ggsition on the su port, would when the'lal is pressed to e face thereof and wrapped around the same, cially, when fully wrapped around, as in igure 12, the ends would show as indicated in the dotted line to meet in an offset position to one another. This is obviated by roviding the supports 74' that are normull; space apart to provlde free action to straddle the article when in the forward position as in dotted lines Figure 8 to engage the sides and tilting the article on its base by the side contact thereof to a true vertical position, the label in this 'po- 'sition of the article is attached thereto, and when wrapped around Wlll. make a proper ali ed connection at the ends, as. will be un erstood. I

The arms 74, at one side or both, may be provided with spring fingers 91, (see Figure 11) of such proportions toyield slightly'to prevent breaking of the articles and accommodate themselves to varying sized articles.

When the slide 14 returns after having I taken a label from the ma azine, the label is than would e the case, of swinging the picker plates to an angular positionas is here done, the plates instead hold the label during their return stroke and laps it further around the article, by slipping or sliding from the angularly disposed picker plates to such a position to have the label wrapped a considerable distance around the article. In many cases labels are not carried completely around the article, and in such a case the wiping station following the labeling station could be omitted, and the complete operation performed at this station, the label supplied with adhesive and afiixed to the article. To completely encircle the article with a label, any wipingmeans may be employed, such as disclosed in Figure 7.

From the foregoing it will be noted by this improvement I am able to apply adhesive to a label substantially covering the full face thereof, at the same station where the the complete labelingoieration is fullycarri'ed out at this one wor station, viz. applying adhesive taking the label from the magazine, appl g the label to the article and wrapping t e same around the article.

It will further be noted, by making an application of adhesive to the article at a prior work station, with the flexible adhesive pad to thereby apply a greater portion to a curved faced article, will not at the next station when the label is removed from the magazine aid the removal of the label therefrom, since contact with the label at the foremost,

or high point of the article is, only a line contact, this would be true also were the en tire face of the label supplied with adhesive at this prior station. In either case this contact is not sufiicient to draw the foremost label from the magazine.

' It is therefore one of the essential features of my improvement, to provide a means to draw the label from the magazine. The bi furcated picker if not of the swinging type,

must straddle the article, and this space between the two part pickers, to enable the passing of the article to make the contact in this direct line action with the label, leaves approximately one-third of the surface of the article without adhesive, to be supplied by some other means. For this reason the flexible pad at the prior work station cannot be dispensed with for some classes of work, and therefore I do not wish to limit my in-' vention to one form alone, as it may even be desirable to use the prior work station with the swinging type of picker plates. In connection with the bifurcated form of picker the flexible pads at the prior work station must be ableto flex into the curved form to lay around the article to cover approximately one-third thereof to provide the adhesive for the full length of the label when joined with the article.
