'lnthill, Grand Rapids, Mich, allignor to Oliver Machinery Mich, a limited partn ompany, Grand Rapids, erahip 01' Michigan Application May 17, 1943, Serial No. 487,233 11 Claims. (Cl. 216-29) This invention relates to labeling machines, and is concerned with an attachment for or an improvement in connection with the label attachingmachine disclosed in my prior Patent No. 2,329,669, issued Sept. 11, 1943.

In the machine shown in the above application, labels are severed in succession one after another at the end of a continuous strip of labels which may be rolled into a roll for ease of handling and economy of space and are successively deposited on the articles and sealed each to its respective article. In such construction the labels are attached each to a substantially flat surface on the article or wrapper in which the article is contained. The tripping and rendering operative of the label feeding, severing and depositing is controlled by the passage of the article substantially in a straight direction underneath the label attaching mechanism so that each article trips and renders operative the mechanism to deposit a label against a surface thereof and seal the label to said surface in the passage of the article.

With the present invention the same mechanism is used for holding the roll of connected labels and for severing them one at a time at the end of the roll in succession, one for each article to'be label equipped. It is a primary object and purpose of the present invention to apply and secure the labels to articles having substantially curved surfaces, for example, phials or the like or other articles of a similar form or contour. It is to be understood that the articles to which the labels are applied are not necessarily of a perfectly cylindrical form but are such that they may 'be rocked, turned or rotated each about its longitudinal axis during the application of the label thereto.

The present invention is concerned with novel constructions for accomplishing the rapid and effective label application and attachment to articles of the type noted, as will be understood from the following description taken in connection with the accompanying drawings, in which,

Fig. 1 is a perspective view illustrating a phial with the label attached.

Fig. 2 is a side elevation of the label attaching improvement by means of which the labels may be attached to the surfaces of phials or like articles having similar form.

Fig. 3 is an elevation from the opposite side of the machine.

Fig. 4 is a plan view of the novel attachment of the present invention.

Figs. 5 and 6 are transverse sections substantially on the planes of lines 5-! and H of Fig. 3 looking in the directions indicated by the arrows. 1

Fig. 7 is a fragmentary enlarged section illustrating the presser roller bearing against a label which is being attached around a substantially cylindrical article, and

Fig. 8 is a diagrammatic view of the electnical wiring and switches for the electric circuit which is used in the operation of the invention.

Like reference characters refer to like parts in .interior mechanism of which is identical with that shown in my prior application. Ser. No. 480,901. Upon energizing the electric mechanism disclosed in such prior application the label strip is fed a step forward and the end label 2 severed from the label upon strip 2a passing above a stationary blade 4 cooperating with which is a movable severing blade 5 as shown in Figs. 3, 7 and 8. identical with the construction in my prior application. The energizing of the electric apparatus is upon completion of an electric circuit which includes the circuit wires 6, l and 8, diagrammatically shown in Fig. 8, in which a source of electric energy 9 is located and with two switches, preferably, between the wire 8 and the wires 6 and 1. Such switches are properly closed in a timely manner in the operation of the machine, as will be hereinafter described, so as to complete the electric circuit and accomplish the feeding and severing of the labels at the proper times therefor.

The label securing structure or attachment to the label feeding and severing part of the mechanism is disposed partly below and partly to the front of said label feeding and severing mechanism. It includes a base H) to be mounted upon the floor, a vertical post II on which the label feeding and severing mechanism may be mounted for vertical adjustment in a manner like or equivalent to that shown in my prior application, and a supporting frame structure which includes the spaced channels I 2 and I3 extending in an upward and forward direction, a short connecting channel I4 between their lower ends and a mounting channel I3 extending horizontally to and secured to the post II. On a bracket I3 mounted on the support I3 an inclined feed chute I1 is secured down which the articles I roll by gravity and pass from the feed chute one after another to a receiving spool or wheel on which they are carried during the time of label afllx- At the upper end of the short supporting channel l2 a horizontal stub shaft I3 is mounted at one part on the web of the channel and at another .part on a plate I3 secured at the open side of the support l2 (Fig. 6). The stub shaft is held against movement and on its projecting free end portion a spool or wheel is mounted for rotation including a central sleeve 23 at the ends of which the sides 2I and 22 of the spool are secured or formed integral with the sleeve (Fig. 6). Between said spaced sides 2| and 22 a pluralityof equally-spaced freely rotatable rollers 23 are mounted around the spool as shown and it is between adjacent rollers that the articles I are to be deposited (Fig. 1) on leaving the chute l1.

The side 22 of the spool farthest away from the support I2 is provided with a continuous series of horizontally projecting pins 24, as many in number as the rollers 23, and located substantially in a circle about the axis of the shaft I3 and at substantially equal radial distances therefrom.

A bracket 23 (Figs. 3 and of Z-form is mounted adjacent the upper end of the channel support I3. A horizontal shaft 23 is rotatably mounted on and carried by said support I3 and the bracket. At the end thereof nearest the bracket 23 a circular disk 21 is secured carrying a pin 23 at a distance from the axis of the shaft 23 (Fig.3). A feed bar 29 is pivotally mounted at one end on the pin 23 and extends downwardly and to the rear to and underneath the pins 24 previously described, the free end of the feed bar 23 being turned and inclined upwardly as shown in Fig. 3 so that the end of the bar may come against one of the pins 24 and underneath the next adjacent pin. A vertical bar 33 is secured to the base I0 and extends upwardly alongside of and between the ends of the feed bar 29. A coiled tension spring 3| is secured at opposite ends to the upper end of the bar 30 and the feed bar 23, the effect of which is to yieldingly elevate the free end of the feed bar 29 against the pins 24 as in Fig. 3. A second short bar 32 is secured at its ends in spaced parallel relation to the vertical bar 33 and between the bars 30 and 32, the feed bar 29 is guided.

A sprocket wheel 33 is secured to the shaft 23 around which an endless chain 34 passes, said chain also passing around a second sprocket wheel 23 mounted on a shaft 33 which in turn has a rotative mount ng upon a suitable supporting bracket or brackets 31 fixed to the base III (Fig. 3). The shaft 33 is the drive shaft of the machine and when the machine is operating is continuously driven from any suitable source of power, thereby through thechain 34 driving the shafts 23 and 33 continuously.

At the upper end of the channel support I3 a bar 33 is secured adjacent one end and extends downwardly and forwardly and has at its free end two spaced upwardly extending ears 39 equ pped with bearings for mounting a short shaft 43 which at one end portion carries a cam 4| of the shape best shown in Fig. 3, that is,

saunas the cam has two are shaped edges. each struck on the arc of a circle but one of a longer radius than the other, the curved edge having the longer radius being slightly greater than semicircular in length and the other of a shorter radius correspondingly less than semi-circular in length. The shaft 43 is continuously driven by a chain 42 passing around a sprocket wheel 43 on said shaft and a corresponding wheel 44 on the shaft 23.

At the upper side of the bar 33 a make and break electric switch 43 is mounted on a bracket 43, associated with which is a pivoted switch closure lever 41 equipped at its free end with a roller which rides upon the edges of a cam 43 on shaft 23. The cam 43 is of the same configuration as the cam' H, the switch lever 41 being elevated to close the switch at 43 upon the roller riding on the curved edge of the cam 43 having the greater radius, and being opened when the lever dropsuponreaching the curved edge of the cam 43 having the shorter radius. This is one of the switches used in the electric circuit diagrammatically shown in Fig. 8 as between the circuit wires1 and 3.

A second switch 43 of a similar construction is mounted on a bracket 33 connected to a side of the label feeding and severing apparatus (Fig. 2) and which carries a switch closing lever 3| which depends from its pivotally connected end downward into the path of movement of the articles I (Fig. 2). Said articles in succession as they come to the switch lever 3I move it to the left (Fig. 3) and successively close the switch 43. Switch 43 is the second switch which controls the closing of the circuit of the operating mechanism of the label feeding and severing machine and is shown as interposed between the circuit wires 3 and 1 in Fig. 8. In practice the switch 49 will be closed a short time ahead of the switch 43. If through any reason anarticle to be labeled should not be deposited between and carried by any two of the consecutive rollers 23, no label will be fed forward and severed because the switch 49 will not be closed, though the switch at 43 is closed and held closed for a time during each revolution of the shaft 23. However the switch 49 is not necessarily used, though desirable, as an operation of the label and forwarding mechanism with no article I provided to which to apply the label severed results only in loss of such label.

. 0n shaft 23 between the upper end of the channel support I3 and the bracket 23 a presser drum frame is pivotally mounted, including a relatively long side bar 32, a shorter side bar 33 and a connecting cross member 34. At the forward ends of the bars 32 and 33 spaced extension brackets 33 are bolted with heat insulating material 33 interposed as shown. A presser drum 31 is mounted for rotation between the extensions 33 of the sides of the frame and is continuously driven when the machine is in operation bya chain 33 passing around a sprocket 39 on the $118. 23 and a similar wheel 30 on the drum At the rear end of the bar 32 a roller 3I positioned to ride against the edges of the cam 4| is mounted at the upper end of a slotted bar 32 through the slot of which an adjusting and securing screw 33 passes to the bar 32 permitting the roller 3| to be adjusted a limited distance with respect to the cam 4|. The drum 31 being relatively heavy in weight normally when free to do so will move in a downward direction but with an adhesive which is of a thermoplastic is adiustably limited in such movement by means of the screw 64 (Fig. 2) threading through a lug 65 extending from the bar 52. the lower end of the screw coming against a stop lug 56 on the channel support I! when in lowermost position.

In the construction shown the drum 5'! is mounted to turn about a hollow sleeve 61, the end portion of which are secured to the extension brackets 55 (Fig. 6). Within the sleeve an electric heating element 58 is located, electric circuit wires 69 being indicated for the conduction of current to the heating element which is heated by the usual resistance coils or the like forming a part of the heat n e eme a In operation, the drive shaft 36 being continuously driven there is a periodic turning in step by step movements of the wheel or spool upon which the roller 23 are mounted for a successive feeding of the articles I rolling down the chute I! to said rollers with successive positioning of the articles between successiv rollers and a supporting of the articles by the rollers as best indicated in Fig. '7.

The feeding is on the movement to the right (Fig. 3) of the feed bar 29, the end of the bar coming against a pin 24. In Fig. 3 the feeding movement has been completed and thereafter the bar 29 is retracted, with a riding of its end portion underneath the next succeeding pin 24, until the bar passes by said pin whereupon it is pulled upwardly by spring .3I against the next pin with the end of the bar in position to push against said nexi. succeeding pin, whereupon with the further rotation of the shaft 26 and the disk 21 such next succeeding pin is engaged I by the end of the bar and a feeding of the article carrying spool or wheel repeated by a step of movement.

Such feeding of the wheel carries the article I about to be labeled against the switch member 5I closing the switch 49. Shortly thereafter the cam 48 operates the switch lever 41 closing the switch 45 whereupon the label f eding and severing mechanism i operated due to the closing of the electric circuit (Fig. 8) and a label 2 is fed and severed from the continuous label strip 2a, the end portion of the label 2 severed being substantially directly over the article I which is to have the label applied. I

While these operationshave been taking place the cam 4I at the edge thereof having the great-er radius will have been riding against the roller 6| depressing the free end of the bar 52 with a consequent rocking of the frame which carries the heated presser roller 51, lifting the roller sufficiently that the extreme end portion of the label will pass between the lower side of the drum 5! and the article I which is to receive the label. but immediately thereafter cam 4| will move to the position in Fig. 3 and the drum come against the upper side of the label. When this occurs or immediately'after it occurs the severing of the label 2 takes place, the article carrying wheel or spool will be at rest, and the feed bar 29 w ll be retracted for engagement with the next succeeding pin 24. The drum 5! rotating continuously and bearing against the label, with the label bearing against the article to which it is o be applied, the result is a rotation of the art c e upon the rollers 23 which carry it and a ccntinuous application of the label 2 to the artic e continuing the wrapping of the label around the article I, the initial portion of which wrapping is shown in Fig. 7.

The under side of the label may be coated nature and becomes oftened and adherent upon the application of heat. The label adheres to the article and the label application is complate. This is the practical form in which the invention has been developed, but it is to be understood that the invention is not necessarily limited to the thermoplastic adhesive requiring the application of heat, therefore a means of heating the presser roller. Other adhesives may be utilized which will adhere without heat application and the present invention is not to be limited solely to the use of heat affected adhesives on the labels and a heated presser roller for softening and rendering the adhesive effective.

For succeeding articles the process is repeated. The presser; roller 57 is lifted when the greater radius portion of the cam 4I again comes to the roller 6|, the feed of the article carrying spool or wheel is moved one step, -moving the next succeeding article to the position previously occupied by that which has had the label applied thereto, and the cycle is repeated as described.

The labeled articles upon continued rotative step by step movement of the article carrying wheel reach a position where they fall by gravity therefrom and are guided by the curved chute Ill (Figs. 2 and 3) out of the machine to, where they may he collected and removed.

The invention is practical and effective for the purposes for which it has been produced. While in the disclosure phials of a cylindrical form are shown as the artcles to which the labels are to b applied one afteranother, it is evident that with some modifications in the carriers for the articles on the article carrying wheel or spool other articles may have labels applied thereto which need not necessarily be of circular cross section.

The present machine as shown is applicable'to apply labels to articles which var somewhat in cross s ctional dimens on, the adjustment of the roller SI and the vertical adjustment of the label feed and severing mechanism providing for a relativelv limited variation in such cross sectional size of the articles. Of course with interchangeable wheels for carrying the articles having a different number of rollers 23 with a, different number of pins 24 and with interchangeable disks 21 to correspond therewith a single machine may be used for labeling articles of still greater variation in s zes.

The invention is defined in the appended claims and is to he considered comprehensive of all forms of structure comin within their scope.
