UNITED STATES PHILIP D. PARSONS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO SCOTT PAPER COMPAN Y, A CORPORATION OF PENNSYLVANIA.

v MACHINE FOR APPLYING LABELS TO PAPER ROLLS, ETC}.

Application filed October 3, 1922. SeriaI'N'o. 592,034.

To all whom it may concern:

Be it known that I, PHILIP D. PARSONS, a citizen of theUnited States, and resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Im- Applying Labels to Paper Rolls, Etc., of which the following is a specification.

This invention is more specifically intended for automatically applying label bands about rolls of toilet or other paper, in an effieient and perfect manner, the same being accomplished more rapidly, more accurately as to positioning, and with cleaner results than has been possible by hand operation.

While my invention isparticularly intended to employ bands which are also labels, I do not restrict myself to the employment of bands of this character; and while the invention is intended for banding toilet paper rolls, it may be employed in connection with v the banding of any other materials in prede termined shape, such as canned or cartoned goods.

)Vith the above and other objects in View, the nature of which will be more fully understood from the description hereinafter,

. the invention consists in the novel construction of machine for applying labels to paper rolls, etc, as hereinafter more fully de- 4 scribed and defined in the claims.

Referring to the drawings: Fig. 1 is a plan view of my improved machine for handing paper rolls; Fig. 2 is a front elevavation of the same; Fig. 3 is a side elevation of the same; Fig. 4 is a horizontal sectional view of the main portion of the machine, taken on line 4-4 of Fig. 2; Fig. 5 is a perspective viewnof a portion of a label or band feeding mechanism; Figs. 6 to 12, inclusive, are horizontal sectional views corresponding to Fig. 4 showin the several steps performed by the mac line in applying the band or label; Fig. 13 is an elevation of a portion of the machine shown in Fig. 3 on a larger scale; Fig. 14 is a sectional view of a detail; and Fig. 15 is a horizontal section show: ing the means for actuating the folders.

2 is the main frame of the machine and supports the table 71. At the front portion of the table 71 and extending laterally to the left is a conveyer frame having, a

R are moved by the ing chains '5, 5, constituting a conveyer; the rolls R being guided between longitudinal side guides 6 of angle iron. The chains 5, 5, are driven by a pulley 74 (Fig. 2) which is rotated by a band or belt 75, in turn moved by a grooved driving wheel 76 secured to a power shaft 52. The shaft 52 is driven by chain and sprocket wheels 53, which receive motion from a power pulley 54 driven by an electric motor 55. The shaft 52 may be driven in any other manner, if so desired. When the paper roll Rleaves the custody of the chains 5, 5, it is transferred to the supporting and feed rollers 7, which are driven by an endless chain 8 from the operating means for imparting movement of the chains 5, 5, (Fig. 4). In this manner, the paper roll R is fed forward until it comes to rest in contact with the abutment plate 9 (Figs. '1 and 2), from which p sition the roll is then fed at right angles against the paper band or label wrapperL (Fig. 6), the feeding bein accomplished by a reciprocating pusher hea 10 (Figsjl-and 4). The pusher head 10 is secured to the end of a rod 56 guided in bearings 57 under the table 71 and is reciprocated by a lever 58 hinged to the main frame 2 and oscillated by link 59 and crank 60, said crank secured to a shaft 49 provided with a gear wheel 50 and driven by a pinion 51 se cured to the power shaft 52 (Figs. 2 and 3).

)Vhen the pusher head 10 advances, it moves yeyer to a position in front of the pusher 10,

it is necessary to provide means for holding back the rolls until the pusher is in outward position to receive a roll. To accomplish this, I provide a spring actuated finger 11 which is forced normally into the position shown in Figs. 1 and 4 by spring 13. The pusher 10 is provided with an automatic trip 14 which, when the pusher is moving outward, causes the finger 11 to be withdrawn to permit one of the rolls R to be fed to the position in front of the pusher; but the trip releases the finger just before the pusher recedes to its outermost position, so as to permit the finger to be forced back to position shown to hold back all of the other rolls. This finger is caused to be reciprocated with each reciprocation of the pusher.

The trip finger 14 is hinged to a lateral extension from the pusher 10 and is held atright angles to the direction of movement of the pusher and the retaining finger 11. by a spring shown at 14 in Fig. 1. As

i the pusher is being withdrawn to permit a roll to pass in front of it, the trip finger 14: will be brought into contact \viththe block 12 on the retaining finger 11 and the spring 14 being sufliciently strong will retain the trip finger in the position shown so that its backward movement. withthe pusher 10 will move the block 12 and the retaining finger 11 backward against the tension of the spring 13, said spring being supported at its outer end by the frame 13 in which the retaining finger is guided. This action moves the finger back sufficiently to allow one of the rolls of paper to be moved past it into position in alinement with the pusher. At this time the pusher is still moving outward and as the retaining finger cannot move outward further, the resistance of the block 12 is such that the trip finger 14 will be oscillated against the action of the spring 14 and its end will slide over the rearwardlv extending plate 12 on the block 12 and ultimately snap over the outer end thereof, freeing the retaining finger 11 sothat it is moved forward under the action of its spring 13 immediately back of the roll which has passed beyond it. When the pusher reverses its movement and advances to push the roll of paper forward against the label and wrapping device, the trip finger 14 will strike the plate 12 and as said plate and its block 12 are held against forward movement by the frame 13, Fig. 1, the finger will again be oscillated as it slides over the said plate 12 and once more assumes the position as shown. In this manner, the trip finger may oscillate in either direction acrording to the resistance encountered but the tension of its spring 14 is always sufficient to enable the trip finger to overcome the spring 13 of the retaining finger.

Referring now to the means for feeding a band or label L intoposition to receive the roll B (Fig. 6), it will be seen that above the table 71 there is a magazine floor 15 having its forward end provided with a chute 23 down which the label L is fed to a position in front of the advancing roll in the custody of the pusher. This chute 23 is open in its middle and lower portion to expose the middle portion of the label and permit the passage of the roll and pusher head (Fig. 4). When the roll R is moved against the label L (Fig. 6) and assumes the successive positions (Figs. 7 and 8), the ends Z, Z, of the band or label are drawn out of the chute pockets and one of said ends, namely Z, when liberated, springs against a paste rod 66 .and receives paste wherewith to seal the overlapping ends, as insured by the operations shown in Figs. 10, 11 and. 12. In this connection, it will be seen that the right hand pocket of the chute is provided with an adjustable guide plate 72 clamped in position of adjustment by screw clamp 73 and adapted to control the time of releasing the end 1 of the band to insure its liberation accurately withthe timing of the paste applying rod 66, whereby the latter is fully raised when the said end Z is released and for the further object of deterininating the amount of paste or glue deposited upon the label. The longer the release of the end I is delayed, the less will be the amount of paste or glue deposited. In receiving the paste or glue, the label end Z wipes against the paste applying rod 66, and to definitely locatethe paste or glue, I provide the rod 66 with a plurality of projections 68 (Fig. 13), which are the places of contact and hence insure deposit of paste or glue in threenarrow and short bands on the flap or end Z. rod 66 is reciprocated vertica ly in the paste or glue pot 67 by'an operating lifter rod 64 having a lateral connection with the Th aste applyi g paste applying rod 66 (Figs. 3 and 13). v

The vertical movement is imparted to the lifter rod 64 by a pivoted lei er 62 having a hinged connection with the main frame 2 at one end and at the other end pressing upwardly againsta roller 63 on the lifter rod, the lever 62 being oscillated by link 61 connected at the top with the said lever and at, the bottom with the crank 60 on shaft 49 before referred to (Figs. 2 and 3). This gives the proper timed reciprocation to the paste applying rod relatively to the reciprocations of the pusher head 10. so that the latter pushes the roll R against the label just as it is in position to take the paste or glue from the rod 66.

Referring now to the means for feeding the labels or bands L to the chute 23: The

labels are stacked in an upright position 1,477,eea

frame 31 and pawl 36 in one direction and a rocking cam frame 30 pushes the frame 31 and its pawl in the other direction against the action of the spring. This frame 30 is oscillated by a vertical rod 29 hinged to it at 28; and said rod is reciprocated by an eccentric 48 on the end-of the shaft 49, before referred to (Figs. 2 and 5). In this manner the stack of labels are moved very slowly forward toward the chute 23 and the forward upper. plate 22 thereof. To give capacit for hand adjustment, I provide a friction clamp 39 between the shaft 19 and the worm wheel 38 and also a winged hub 40 on the end of the shaft. By turning the shaft 19 by hand, the chains 18 may be operated to move the support 16 forward or backward in order to insert a new stackof labels or to adjust the stack forward into operative position to initially cooperate .with

the suction feed arms 21.

20 is a hollow rock shaft journaled at each end in the side frames of the magazine floor 15. Extending laterally from this hollow rockshaft are a plurality of tubular suction arms 21, the open ends of which are in the same plane and adapted to press simulta: neously in contact with the front sheet of the stack of labels L and by suction pull the label away from the others and move it forward above the chute 23. When the label reaches a position above the chute, the air suction is shut off, permitting the label to fall and this is insured by the plate 22 which 5 acts as a stripper to the label as the suction arms pass forward beyond said plate. The floor of the magazine 15 is provided with supporting strips 17 (Fig. 1) of rubber or other material which presents frictional resistance to the edges of the stack of labels, with the resultthat when the suction arms 21 pull away thefront label of the stack, the remaining labels retain their normal position. The hollow rock shaft 20 is provided with a gear wheel or segment 26 which meshes with gear or segment 27, the latter being secured to the oscillating cam frame 30 and is thereby oscillated by the means heretofore described for operating the cam frame 30. The suction is provided by a suction pump 24 with which the rock shaft 20 is connected by a flexible hose 25 (Fig. 5). The position of the suction pump is reciprocated by a crank 24*, which is driven from shaft 49 by gears 49" (Fig. 14). As the operation of the pusher head 10, the lifter rod 64 for the paste applying rod, the feeding means for advancing the labels. the rocking devices for the suction pipe 20 and the suction pump are all actuated from the same power shaft 49, it is manifest that all of these cooperating means and devices will be operated in timed relation.

A the feeding of the labels will take place automatically with each revolution of the shaft 49, if not otherwise prevented, when there is no paper roll R passing through the machine, I rovide an automatic controlling means whic 1 prevents the feeding of a label into the chute 23 whenever there is no paper roll R passing along the conveyer elements 4 and 5. This means valve 41 on the suction end of the suction pump and an operating rod 42, which when raised opens the valveand prevents the pump creating an operative suction through the pipe 20 and its suction arms 21. This rod 42 1s hinged to a pivoted trip 43 which is hinged at 45 to the conveyer frame 3, said trip being counterweighted at 46, so that it projects above the floor 4 of the conveyer when no paper rolls R are holding it down. Inthis manner, when the rolls R are present, the rod 42 is held down and out of contact with the relief valve 41; but when no rolls are present on the conveyer, the counterweight 46 forces the trip and rod upward with the result that the relief is opened and suction prevented.

I will now describe the successive steps illustrated in Figs. 6 to 10, inclusive, which disclose the operations in encircling the paper roll with the band or label. As before explained, Fig. 6 shows the roll R moved by the pusher 10 into contact with the label L to be applied to it. Fig. 7 shows the same roll pushed further back and causing the label to be partly wrapped about the roll and the end Z brought into contact with the paste applying rod 66, said label end having just passed from the custody of the plate 72 of the chute 23. Fig. 9 shows the paper roll and its label pushed still further back to the limit of the movement of the pusher head 10 and into the custody of the wrapping arms 74 which hold the label wrapped about the roll and with the free ends Z, Z, in position to be folded one over the other into pasted relation. The wrapping arms consist of two hinged arms 74 between which the paper roll passes, said arms curved toward each other at their forward ends and provided with small vertical rollers 74 said arms hinged at 75 to the rigid guide walls secured to the-floor 71 and spring pressed toward each other by the springs 76. Fig. 10 shows the folder 78 in action, as having just folded the unpasted end Z of the label down upon the roll. Fig. 11 shows the same.

general relation of the parts, but in this case the folder 78 is just receding while the other folder 84 is folding down the pasted end Z of the label; and F ig. 12 shows the folderc78 fully receded and the folder 84 fully advanced to complete the folding down of the pasted end Z of the wrapper. After this operation is completed the next roll is moved forward and pressed against the pasted overlapping ends Z, Z and prevents said ends separating to produce 'a defective sealing.

comprises a relief pivoted finger hinged to the laterally reciprocating slide 77 and spring pressed toward the roll by a spring 80. Similarly, the folder 84 is hinged at 85 to a laterally reciprocating slide 83 and is spring pressed toward the roll by a spring 86, this last folder being provided'with a pair of vertically roll ers journaled in a pivoted truck 84 to more perfectly roll down the pasted end] of the label. These folders 78 and 84 may be made in other forms if so desired, but should move successively so as to fold down the two ends of the label in succession.

The reciprocating plate 77 of folder 7 8 is Y secured to a reciprocating rod 81 which is spring pressed by spring 82 to force the folder 78 to the folding position shown in Fig.10; and similarly the plate83 of folder 84 is secured to areciprocating rod 87 which is spring actuated by spring 88 to move the folder 84 from position shown in Fig. 10 to position shown in Fig. 12 or in a reverse direction to that given to folder 78 by its spring 82. The rod 81 is controlled by abellcrank lever 89 and cam 90 movable with the pusher operating rod 56. Similarly the rod 87 is controlled by a bell-crank 91 and cam 92 also movable with the pusher rod 56.

It will be seen from Figs. 10, 11 and 12, that the folder 78 first advances to turn down the unpasted label end 1' (Fig. 10), then the folder 84 moves forward from the opposite direction to turn down the other or pasted end Z of the label while the folder 78 slightly recedes (Fig; 11), and finally the folderf78 is fully drawn back while folder 84 continues to advance and fully fold over and press down thev pasted or glued end Z upon the end Z (Fig. 12). Folder 84 remains in this position until the next paper roll R is pushed in by the pusher head 10, and then it is released and withdrawn; and the new roll to be handed with its label is pushed by the pusher between the spring actuated wrapping arms 74 and forces back the banded roll just completed, as will be understood by reference to Fig. 4. In this way. the succeeding rolls, which are fed in by the pusher. cause the banded rolls to progressively travel rearwardly through the guideway 69 formed between the side frames 70 and 70 to the place of discharge for packing in the shipping cases. During this rearward travel, the rolls are in close contact and in this manner hold the pasted ends Z. Z, of the wrappers in 56, insures a timed operation of the bellcranks 89 and 91 and resulting reciprocation of the folders 78 and 84 which take place through the medium of the connecting mechanism com rising the spring controlled slide 81 for pus er 78 and sprin controlled slide 87 for folder 84. In t e position 56, the cam 90 operates bell-crank 89 to withdraw folder 78, andcam 92.0perates the bell-crank 91 to advance the folder 84, as shown in Figs. 10, 11 and 12. This position of the vfolder 84 (Fig. 12) remains until the latter part of the advance of the pusher is being completed to force the new roll and band into the wrapping arms 74 (Fig. 9) and is then rapidly withdrawn, just in time to allow the new roll to be brou ht into contact with sealed band or label Fig. 4).

It'will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to .be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.
