Grand Rapids, Mich, assignor to Oliver Machinery Company,

Grand Rapids,

Mich, a corporation of Michigan Application July 31, 1940, Serial No. 348,697 12 Claims. (01. 2216-29) This invention relates to a label attaching machine adapted to be associated with a wrapping machine. The present machine, in the structural embodiment which I- have devised, is adapted to be connected with a wrapping machine of the character shown in the pending application, Serial No. 247,063, filed December 21, 1938, by myself jointly with Howard B. Tuthill. In such wrapping machine loaves of bread may be wrapped though it is not necessarily restricted to bread wrapping alone.

Loaves of bread or other articles, subjected to being wrapped for protection or preservation desirably should be labeled, and the present invention is directed to a label attaching mechanism or machine which can be used with the wrapping machine and with which simultaneously with the wrapping of each article a label is supplied to and connected with the wrapper.

Such label may carry any desired indicia such as the name of the article, its trade name, or any advertising with respect thereto. It is the primary object and purpose of the present invention to provide a label attaching mechanism for' wrappingmachines whereby each. article wrapped will have secured to the wrapper a desired label. Therefore, the wrapped articles are complete both as to wrapping and labeling when passed through the wrapping machine equipped with the label attaching machine of my invention.

Other objects and purposes subsidiary to the primary object stated, together with novel constructions, arrangements and associations of parts for obtaining the same will appear and be understood from the following description of a preferred form of construction of my invention taken in connection with the accompanying drawings, in which-- Fig. 1 is a fragmentary vertical section and elevation through one end of a wrapping inachine having the label attaching machine of my 1 invention connected and combined therewith, the

Like reference characters refer to like parts in the different figures of the drawings.

Thewrapping machine to which the label at taching machine of my inventionis connected includes spaced side frames 5 which are joined together by cross beams 2. The wrapping material or paper 3 is carried in a roll t at an end of the wrapping machine, and as will later be described, passes over a plurality of guiding rollers to lower and upper rollers 5 and t, roller 5 being a driven roller and roller t bearing thereagainst so that the wrapping paper is pulled from the roll 41 and carried between the rollers 5 and t to the wrapping mechanism, it. being understood and as will appear inv the pending application to which reference has been made that predetermined lengths of the paper are cut from the continuous sheet, one for each article which is to be wrapped.

The label attaching machine of my invention.

includes a supporting housing having an upper side i and depending ends t spaced from each edge of the top 1 which is bolted or otherwise permanently connected with an upper cross beam 2 of the wrapping machine (Figs. 1 and 2). A post I is secured to the top member 1 ofthe housing on which a rod or shaft II is mounted. A spool I2 is rotatably mounted on the rod H and held between suitable collars on which spool a roll iii of labels is carried. The labelsv l4 which make up the roll |3 are integrally connected in consecutive order and are partially separated from each other by slots l5 extending inwardly from each side edge between adjacent labels :as best shown in Fig. 9, leaving relatively narrow connecting portions l6 between consecutive labels l4.

From the roll 13 carried by the spool |2 the connected together labels are led downwardly over a cylinder l1 fixed to a shaft l8. Four sets of pins 19 extend radially outward from the 7 cylinder H and are associated in pairs so that when the continuous strip of labels passes around the roller H the pins l9 enter the slots i5 as shown in Fig. 9, thereby maintaining and keeping the labels in proper position and feeding them a ,into the machine in proper timed: relationship to the cut-off knife which cuts the end label from the strip, one after the other, as articles in the wrapping machine are wrapped one after the other. Such cutting knife and its operation will be hereinafter described.

An arm 2|! (Fig. 4) is mounted at one end upon the rod or shaft II and has a rod 2| connected to its other end which extends parallel to the axis of the roller |1'. 0n the rod 2| two spaced apart rollers 22 held apart by a coiled spring 23 and against suitable collars fixed on said rod 2| are mounted and pressed by gravity against the edge portions of the label strip holding the same against the cylinder l1. 7

The shaft IS on which the cylinder I1 is secured is mounted for rotation in the ends of an 24 bolted to the main housing auxiliary housing of the label machine and extending outwardly therefrom, said auxiliary housing 24 being located adjacent one end of the main housing and the shaft i8 extending beyond said housing toward the center of the machine. A coiled compression spring'25 bearing at one end against the housing 24 and at the other end against a collar fixed on the shaft l8 has the effect of frictionally holding the shaft I3 against too free or aimless movement. A disk 26 (Fig. 10) is fixed to the shaft l8 and has a plurality of spaced apart concave notches therein. A lever 21 mounted upon a horizontal shaft 28 which extends the full length of the main housing, at one end has a roller 29 adapted to enter the concave notches in the disk 26 being yieldingly pressed therein by a spring 30 acting upon the opposite end of the lever. The feeding of the labels, one after the other, is by a periodic step by step movement,

.the shaft l8 turning one quarter of a revolution at each movement and with an interval of rest between each step, the spring actuated detent provided by lever 21 and roller 29 acting to maintain the shaft l8 and the cylinder l1 about which the label strip is carried against any change of position and insuring that the feeding of the labels shall be accurate and of the same amount with each step of feeding movement.

' A sprocket wheel 3| is secured to the shaft I8 around which an endless sprocket chain 32 is carried (Figs. 1 and 2) The chain also passes around a second sprocket wheel 33 loosely mounted upon the shaft 28. A ratchet wheel 34 is conother, there being a vertical flange 9 at the inner nected with the sprocket wheel by pins 35 (see Fig; 8) the parts being held together by the collar 36 secured to the shaft 28 and holding the ratchet wheel against the end of a bushing 31 which is mounted upon and passes through an end 8 of the main housing of the label machine. A relatively wide arm or plate 38 extendsdownwardly and inwardly toward the wrapping machine from the inner end of the bushing 31, being either integral therewith or permanently secured thereto. A ratchet dog 39 is pivotally mounted between its ends on the plate 38 and has its ratchet engaging end below the ratchet wheel 34 (Fig. 1). An arm Al is secured to the bushing 31 atthe outside of the end 8 of the main housing and at its free end is pivotally connected with a vertical rod 42 which extends downwardly alongside of the end'of the wrapping machine. At the lower end of the rod 42 a collar 43 is secured. The rod passes freely through a block 44 located above and bearing upon the collar 43 and between this block and a collar 43a secured at a higher point on the rod 42, a coiled compression spring 44a is disposed. The block 44 is pivotally mounted by means of trunnions 45 upon the end of an arm 46 which is secured to a rock shaft 41. The rock shaft 41 isa part of the mechanism of the wrapping machine which is operated as the heretofore identified pending application discloses to provide a periodic or intermittent feed of the wrapping paper.

The ratchet dog 39 rests at its weighted end upon a lever 48 mounted for free movement about a horizontal rod 49 extending between the ends 8 of the main housing. A rod 50 (Fig. l) is con nected to the-free end of the lever 48 and extends upwardly to and has associated therewith a core of an electric solenoid 5| whereby when the solenoid is energized the rod 5|] is moved vertically, the lever 48 is turned counter-clockwise about the shaft 49 and the ratchet engaging end of the dog 39 lifted so as to engage the ratchet wheel 34.

In Fig. 1 the arm 46 is at its lowermost position. The line indicated at A joining the centers of trunnions 45 and the shaft 41 is carried successively to 'the positions B and C, the latter being the uppermost position of movement of the arm 46. In moving from position A to position B the arm 4| will be elevated, turning the bushing 31 and turning the plate 38 from the full line position shown in Fig. 1 to the dotted line position shown or until it engages with a limit stop 40 on the machine housing. In such movement of the plate 38, the dog 33 being connected with the ratchet wheel 34, shaft 28 will be turned a limited distance and through the construction described will turn the shaft IS a one quarter turn previously mentioned. But the arm 46 may continue to its upper'movement indicated by the line C in Fig. 1 without any further feeding move ment of the labels, the spring 44a being compressed. On the return of the arm 46 to its lowermost position in moving from the position at C to that at position B the spring 44 will be extended and in the following movement from position B to position A the member 38 will be returned from upper to lower position and the dog 39 carried to aposition where it can engage the next succeeding tooth of the ratchet wheel. Thus with the rocking movement of the shaft 41 there is a step by step feeding movement of the label strip, with intervals of rest between steps of movement. It is'offcourse understood that if the solenoid is not energized then no labels will be fed to the wrapping machine and the machine will wrap the articles without labels, the same as though the label attaching mechanism was not present. Therefore when labels are to be supplied to the wrappers an electric circuit containing the solenoid is closed to pass current therethrough.

Two

shafts

52 and 53 on which

rollers

54 and 55 are respectively carried are mounted in hori-.

zontal alinement with the rod 49 (Fig. 2) and at opposite sides thereof. A horizontal table 56 is secured to; extends lengthwise of and is located above the rod 49 which serves as a support therefor. At its upper side the table 56 is substantially flush with the uppermost portions of the

rollers

54 and 55. A horizontal shaft 51 is mounted below and is located between the

shafts

52 and 49 and from which two spaced apart arms 58 (Fig. 4) extend downwardly and toward the wrapping machine. Between the lower ends of the arms 58 a roller 59 is mounted between a short stud shaft 68 carried by one arm and an adjustable screw 6| by the other arm, the ends of said

parts

60 and 6| and the ends of the roller 59' havingsuitable anti-friction bearings between them whereby the roller 55 is freely rotatable. The roller may be readily removed with the described structure. The wrapping paper 3 is carried upwardly from the roll 4 over the roller 54 across the table-55 and around the roller 55 downwardly to the roller 59 and thence upwardly over the roller 5 into the wrapping machine, as shown in Fig. 2.

The

shafts

52, 5s and 51 are mounted at their end portions in suitable bearings on the sides 8 of the housing. The shaft 51 is carried through one of said ends 8 and is equipped with a flat disk 62 at the upper part of which is a graduated indicating scale 63 which moves with respect to a fixed pointer 64 on a housing 65 secured to the associated end 8 of the main housing (Figs. 4, 6, and 7). A worm gear segment 66 is secured to the inner side of the disk 62 within housing and at one end is equipped with an operating hand wheel 69. By turning the hand wheel the shaft 51 may be adjusted to diiierent positions with corresponding changes in the positions of the roller 59. The object of this construction is to adjust the label to the wrapper onto which the label is delivered so that the label will be properly located upon the Wrapper, so that when it is wrapped around an article the label will appear in a desired location and position with respect tothe wrapped article.

The label strip upon leaving the drum H is carried to and over a roller 10 on a shaft a (Fig. 4) which is mounted in bearings in projecting arms ll extending downwardly from the auxiliary housing 24. A drum or pulley 72 on the shaft 18a has grooves therein to receive endless belts 13 which pass around it andalso around the roller 54 to thereby drive the roller 10. Lying over and against the roller 10 or against the labels passing thereover is a. second roller 74 which, as'shown in Fig. 4, is'annularly grooved at spaced apart points between its ends to provide a plurality of spaced apart roller sections which bear against the labels. The roller 14 is mounted in rectangular shaped bearings 15 (Fig. 2) which are received in vertical slots in brackets 15 bolted at the outer side of-the main housing. The roller 14 by gravity bears against the label strip to press it. against the roller 10 and has capabilities of a limited vertical adjustment so that on entering a new labelstrip into the machine,-

roller 14 is elevated to permit the and label to pass between it and the lower roller l0. Rollers 1B and 1'4 are geared together by pinions 11. (Fig. 4) of the same size so that they turn equally in opposite directions.

The label strip fed downwardly and inwardly through the

rollers

18 and 74 passes between flat guides 18 (Fig. 2) immediately beyond which the end label is cut from the continuous strip of labels by a cutting knife 19. The knife 79 is secured at its ends to two arms 80 and 80a struction shown in Figs. 1 to 10 inclusive, has a bels M to the gether.

mounted to rock upon the rod 69. The arm 88 is the upper arm of a bell crank lever (Fig. 2), the other arm 8! -of which extends downwardly and is connected by a link 82 (Fig. 1) with an upwardly extending arm 83 secured at its lower end to a bar 84 which is pivoted at one end to rock about the axisof a rod or shaft 85 mounted upon and extending between thesides of the main frame i of the wrapping machine. The free end of the bar 84 carries a roller 85 which rides upon a cam drum 87 having a fiat side 88 which comes to the roller 85 so that at a predetermined portion of the rotative movement of the drum 87, roller 86 following the flat section 88, there is caused a downward movement of the knife 19 to cut the end label from the strip of labels and deliver it onto the wrapping paper immediately over the.roller 54. The drum Bl is secured to a shaft 89 of the wrapping machine. Such drum 8'?! in the wrapping machine, as shown in the previously identified application, among other things controls the cutting of the wrapping paper to desired lengths. one for each article to be wrapped, and also the elevator cam of the wrapping machine which is used in the wrapping operation. I

The shaft is at one end (Fig. 4), in the conhand-lever 58 thereon for manual rock the shaft for ing element used operation to raising or lowering the heatin cementing or fixing the lawrapping paper. On the shaft 28 two arms 9! are fixed (Figs. 2 and 3) and are connected by a cross plate 92. The arms extend downwardly and inwardly toward the wrapping machine and attheir inner ends carry a shaft 93 on which a grooved drum 9 2 is mounted. The shaft 93 also has mounted thereon two arms 95 which extend outwardly to a position underneath the rock shaft 28 and carry a roller 96 which rides upon and over the roller 5 with the wrapping paper 3 between such rollers. It is also evident that the. severed labels pass underneath the roller 96 and are held against the surface of the wrapping paper 3. The roller 96 is also grooved similarly to the drum 84 and in the corresponding grooves of the two rollers or drums, endless metallic belts 9i! are located.

These belts are comprised of lengths of closely coiled wire, the ends of which are secured tothe table 96, paper 3 andthe labels i4 lying against the paper, and through grooves made therein for their passage in the under side of a heating plate 88which is heated by an electric heating element 98 fixed above it, said plate being carried by and suspended from the arms 9| (Fig. 2). A label 54 bearing against the upper side of the wrapping paper, and held thereagainst by the lower runs of the belts 91 is caused to firmly adhere to and have a cemented connection with the wrapping paper through the The Such belts pass over the upper side of efiect of heat supplied by the heating plate 98. cementation of the label to the paper ing a pivotal connection through the effects of heat may besecured in many ways by any one of a number of suitable adhesive compositions sufficient to cause such adhesion and which are rendered effective by heat as is well known to those in the art.

This connection of the labels to the wrapping paper through the use of heating will occur only with the plate 98 in its lower operative position as shown in Fig. 2. Rocking the rock shaft 28 by the handle 98 swings the arms Si in a counter-clockwise direction or upwardly and lifts the plate to an inoperative position. This may be done at times when articles are'wrapped without any labels being used and connected to the wrapper. It is also desirable to lift the heating plate and hold it in its lifted position when the machine is not in operation. Forthis purpose a'yoke I93 (Figs. 3 and 5) is secured to the rock shaft 28, having two spaced apart arms. A rod i9! is connected with a stirrup I02 which is mounted for rocking movement on the shaft 53. A coiled compression spring I03 surrounds the rod Hll bearing at one end against the stirmp 102 and at the other end against a washer which in turn comes against a cross-pin I84 rotatably mounted at its ends and extending between the arms of the yoke I09, the rod lfll passing slidably through the cross-pin I04. This provides a toggle lever structure which may be snapped from one side to the other. In one position on rocking the shaft 28 in a selected direction, theheating mechanism will be low-- ered and in place for operation as in Fig. 2. In the other position the heating element will be lifted and held in inoperative position.

-With this construction the wrapping paper being carried into the machine in accordance with the application previously identified, has delivered to it at properly spaced intervals the labels [4 which are carried against the upper side of the wrapper over the table 56 and are adhesively connectedto the paper through the efiects of heatas described. After leaving the heating mechanism the labels are firmly connected 'to the upper side of the carried with it into the wrapping machine. When the loaf of bread or other article is wrapped the label preferably will be located at the upper side of the wrapped loaf and being permanently connected to the section of wrapping paper used in wrapping such loaf will go with the wrapper and loaf. A label is severed from the continuous strip of labels for every length of wrapping paper severed from the continuous length of wrapping paper, is firmly cemented to such length of wrapping paper and is on the wrapped article when the wrapping is complete.

In Figs. 11 to 14 inclusive, some changes inpaper and are volving additions and eliminationslin structure 1 from that described are provided for automatic'ally controlling the heating plate instead of manually by a rocking of the shaft 28 by the hand lever 90. The shaft 28 is extended a short distance through sleeve 31 and is equipped with an arm I05 (Figs. 11 and 12) connected to the shaft at one end, the opposite end havto a vertical bar I96 which is secured to the upper end of an air cylinder I01. Within the cylinder is a piston I08 connected to. a piston rod I09 which at its lower end is connected to a bar I I0 pivot-ally attached at its lower end to the rocking arm or lever 46. Therefore, with each rocking movement of the arm 43, shaft 28 is likewise rocked to lift and lower the heating element. The piston-cylinder construction provides a yielding and cushioning dash pot construction.

The toggle lever construction shown in 'Fig. 5 is modified by positioning the yoke I100 and the rod llll 'at different angles with respect to each other so that the rocking of the shaft 28 merely compresses spring l83gbut does not carry its line of force across dead center as in the first described structure. The spring I03 counterbalances the weight of the heating plate. The

heating plate 98 with the electric heating ele- I ment 99 .thereabove is not carried in thisconstruction by the arms 9! but is connected through a vertical link ill with an arm H2 fixed to the shaft 2-8 whereby the heating plate is lowered and lifted with the rocking of the shaft. The arms 9| in this construction (Fig. 14) are not secured to the rock shaft 28 but are loosely mounted thereon at one end whereby the structure comprising the arms 9|, rollers 94 and 9B and the arms remains in its lower position with the rollers against the wrapping paper 3. Also the belts 91 are not used.- Between the heating plate and the roller 93 a plurality of metallic members H3 formed of flat metal and suspended from a rod H4 extending between the arm 95 are used, each at its lower end having a horizontal section lying directly over the paper 3 and serving to hold it or labels thereupon against any attempted upward movement.

A label l4 having been deposited upon the wrapping paper 3 is carried underneath the roller 96 and over the roller 94 with the paper to a position under the heating plate 98. When it reaches the proper position the movement of the wrapping paper there occurs a downward movement of the heater plate through the rocking of shaft 41 in a counter-clockwise direction (Fig. l) and a downward movement of arms 46 and I05. When the paper and the labels are simultaneously moving in their step by step movement into the machine the heater is lifted.

If it should happen that the wrapping machine and associated label machine are stopped 3 stops and with the heater plate in its down position, spring I03 having been compressed has a sufiicient-force to move the mechanism associated therewith including the rock shaft 28 to lift the heater to its upper position, thus guarding against danger of the heater burning or damaging the wrappin paper immediately'below it as would occur if the paper was stopped'and theheater in lower position stayed closely thereabove for a length of time.

The construction described is very practical and useful and has proved particularly desirable in connection with labeling wrapped articles simultaneously with their wrapping. Attachment of labels to articles already wrapped is unsatisfactory and slow. With my invention and without the employment of additional labor the label attachment is efiected with sureness and certainty and with complete uniformity. As previously pointed out the wrapping paper passing into the machine may be adjusted and gauged by means of the roller 59 which can be shifted to different positions so as to govern the relative positions at which the labels will be deposited upon the paper and therefore the relative position of each label to a length of paper which is severed from the roll for wrapping each article step by step.

and is to be considered comprehensive of all forms of structure coming within their scope.
