LABELING-MACHINE.

Specification of Letters Patent.

Patented June 2'7, 1916.

Application filed December 30, 1909, Serial No. 535,658. Renewed May 3, 1916. Serial No. 95,251.

To all whom it may concern Be it known that I, NELSON MUsLAR, a citizen of the United States, residing at Worcester, in the county of Worcester and State of lVIassachusetts, have invented a new and useful Improvement in Labeling-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for pasting labels on bottles or other receptacles of similar form.

One object of the invention is to produce a labeling machine which will be capable vibration and consumption of power, and to this end I employmechanisms for actuating the label pickers and wipers arranged to move these parts in opposite directions at the same time so as to counterbalance and neutralize the tendency of these parts to produce vibrations in the machine owing to their respective movement.

Another object of the invention is to provide a bottle-labeling machine with improved means for supplying adhesive to the label pickers, and to this end I employ a pump of novel construction and arrange ment which will be more particularly described hereinafter.

A third object of the invention is to produce improved devices for holding and feeding the labels, the label-holding devices being capable of adjustment for different sizes of labels and such adjustment being accomplished without change in the general position in which the label is applied to the bottle.

Other objects and features of my invention will be set forth in connection with the description of the illustrated embodiment of the invention.

In the accompanying drawings, which illustrate the preferred embodiment of my invention, Figure 1 is a side elevation of the labeling machine complete; Fig. 2 is a front elevation of a portion of the machine, the label holding devices and the base portion of the same being omitted; Fig. 3 is a vertical section of the machine taken on the median plane looking from right to left; Fig. 4 is a plan view, showing in detail the label holding devices; Fig. 5 is a section on line 55 in Fig. 4; Fig. 6 is a section, on an enlarged scale, on line 6-6 in Fig. 3, showing particularly the construction of the adhesive pump and valve; and Fig. 7 is a section of the driving clutch on line 77 in Fig. 8.

The operative instrumentalities of the illustrated embodiment of my invention comprise a bottle rest 8 upon which the bottle is supported during the labeling operation, label-holding devices by which stacks of labels 9 and 10 are held above the bottle rest, label pickers l1 and 12 by which the labels are transferred from the label-holdof operating at high speed without excessive I ing devices to the bottle and by which the paste is applied to the edges of the labels, a clamp 13 by which the labels are held in place upon the bottle, and two wipers 14 by which the labels are pressed smoothly upon and secured to the. bottle. The machine is also provided with a member 15 which serves both as a gage to determine the position of the bottle on the bottle rest and as an element of automatic mechanism for setting the machine into operation when a bottle is placed in position on the rest.

The bottle rest 8 has a concave upper surface adapted to center the bottle in the machine when laid upon its side on the rest, as shown in Figs. 1 and 3. The rest is mounted with a vertical tongue-andslot connection upon a bracket 16 constituting a portion of the frame of the machine, and by means of an adjusting screw 17 the bottle rest may be adjusted vertically to compensate for differences in the diameters of the bottles operated upon.

The label pickers 11 and 12 are similar in construction to those illustrated in Letters Patent No. 82 L569, granted to me June 26, 1906, being hollow and provided upon their operative surfaces with perforations through which paste or other adhesive is fed. In the present machine the operative surfaces of the pickers are directed upwardly and are substantially horizontal, as shown in Figs. 2 and 3.

The label pickers are mounted upon hollow stems 18 at either side of the position occupied by the bottle, and the stems 18 project forwardly from two upwardly-extending arms 19 connected at their lower ends by a yoke 20. The yoke 20 is arranged to move vertically so as to raise and lower the label pickers, and to this end it is mounted upon two vertical slide rods 21 which move in guides 22 on the frame of the machine.

The adhesive is supplied to the label pickers by means of a pump which is carried by the yoke 20 so as to participate in its ver tical movements. The pump cylinder 23 is supported by two rods 24- connecting it rigidly with the yoke 20. A reservoir 25 is fixed to the front of the pump cylinder, carries the supply of adhesive, and it is connected with the pump cylinder by a passage 2G controlled by a valve 27. The valve 27 also controls an outlet passage 28 through which the adhesive is pumped into two vertical tubes 29. The tubes 29 connect the pump with the hollow stems 18, and thus adhesive is conducted from the pump to the label pickers.

The pump piston 30 is provided with a piston rod 3lwvhich extends downwardly from the pump cylinder and passes loosely through an opening in the lug 32 on the frame of the machine. Adjustable stop nuts 33 and 34 are arranged upon the piston rod 31 above and below the lug 32. This arrangement is such as to permit the pump piston to be actuated through the vertical movement of the pump cylinder with the yoke 20, but with a stroke considerably less than the amplitude of movement of the yoke and the label pickers. Throughout the greater part of the vertical movements of the pump cylinder the piston moves with the cylinder and is inoperative, but, shortly before the extremity of the upward movement is reached, the stop nuts 34 engage the lower surface of the lug 32 and cause the piston to be drawn downward in the cylinder for a short stroke, of which the length may be adjusted by changing the position of the stop nuts 34 on the piston rod. The piston is moved in the opposite direction by the engagement of the stop nuts 33 with the lug 32 shortly before the extremity of the downward movement of the pump cylinder.

The valve 27 connects the pump cylinder with the outlet passage 28 during the outward stroke of the piston so asto cause the adhesive to be forced into the tubes 29, and it connects the pump cylinder with the inlet passage 26 during the inward stroke of the piston to cause the adhesive to be drawn from the receptacle 25 into the pump cylinder. The valve is actuated by means of two arms and 37 carried at one end of the valve in position to engage a pin 36 projecting inwardly from one of the guides 22-. During the upward movement of the pump this pin engages and depresses the arm 37 so as to move the valve into position shown in Fig. 3, while during the downward movement of the pump the pin engages and elevates the arm 35 so as to move the valve through a quarter-revolution, thus closing the passage 28 and connecting the passage 26 with the pump cylinder.

The above-described arrangement of the pump avoids the necessity of flexible connections between the label pickers and the pu1np,'or between the pump and adhesive receptacle, thereby increasing the durability of the mechanisms and the positiveness of the feeding action upon the adhesive. The adhesive supplied by the pump at each stroke exudes upon the label surfaces of the label pickers through the openings hereinbefore described.

The labels 9, which are applied to the bodies of the bottles, are held in the label holder which comprises two vertical members 41 and 42 which engage the front and rear edges of the stack of labels. These members are adjustable toward and from each other to adapt the label holder to labels of different sizes, and for this purpose the members 41 and 42 are mounted to slide upon two parallel horizontal rods 43 which project forward from a. yoke 44 mounted upon the frame of the machine. The members 41 and 42 are moved, for the purpose of such adjustment, by means of-a rightand-left-hand screw 45, having threaded engagement with the said members, and provided with a hand wheel 46 by which it may be turned. The members 41 and 42 are provided at their lower extremities with narrow lips 47 which engage the labels at their edges and serve to support the labels in the holder without preventing the removal of the lowermost label by the label pickers.

The ends of the labels are engaged and positioned by vertical guides 48 which are fixed to arms 50, slidably mounted upon transverse horizontal guide rods 51. The guide rods 51 are fixed upon laterally-extending arms on the yoke 44. The end guides 48 are adjusted to accommodate labels of different lengths by moving the arms 50 upon the guide rods 51, and for this purpose the arms are engaged by a right-and-lefthand adjusting screw 52, provided with a hand wheel 53 by which it may .be turned. The end guides are also provided with narrow lips 49 to retain the labels in the holder.

When the label pickers rise in the operation of the machine, the pickers 11 move into engagement-with the lowermost label 9 in the label holder, and the adhesive upon the surfaces of the pickers is thus applied to the marginal portions of the label at its ends. lVhen the pickers 11 fall again, the label adheres to the pickers and is drawn out the bottom of the label holder. The other labels are retained in the holder bv means of the lips 47 and 49. The label thus withdrawn is laid across the upper surface of the body of the bottle by the downward movement of the pickers, and is then in position to be pressed against and secured to the bottle by the wipers.

To insure the feeding of the labels from the label holder, a follower in the form of a plate 54 is laid upon the top of the stack of labels. The weight of the follower is suffi- ,cient to insure the regular downward movement of the labels as they are removed one by one, while not suflicient to press them so firmly. against the lips as to substantially resist the withrawal of the lowermost label in the manner hereinafter described. To insure the adhesion of the lowermost label to the pickers and the application of the adhesive to this label, it is desirable that the pickers be pressed against the label with a force greater than that necessary to raise the follower 54, and for this reason the fol lower is provided with means for resisting the upward movement of the follower when the pickers engage the lowermost label. To this end vertical rods 55 are mounted .on the arms 50 and are provided with toothed inner surfaces. Guides 56 slide freely upon the rods 55, and pawls 57 are pivoted on the guides in position to engage the toothed surfaces of the rods 55. These pawls carry spring-pressed plungers 58 which bear against the upper surface of the follower 54. The pawls and guides follow the follower in its downward movement as the height of the stack of labels diminishes, but whenever the follower tends to rise under pressure of the pickers against the bottom of the stack the pawls 57 are moved into engagement with the rods 55, which prevents their upward movement. The plungers 58 then act to resist the upward movement of the follower, while the springs by which these plungers are pressed downwardly permit sufficient yielding of the follower to prevent the production of undue pressure between the pickers and the labels.

The machine is provided with a second label holder adapted to hold labels to be applied to the neck of the bottle by the pickers 12. The neck-label holder has end guides 60 which engage the ends of the crescent-shaped neck labels and which are provided with lips at their lower extremities for the purpose hereinbefore referred to. A

'front guide is also provided to engage the middle of the front edges of the neck labels. The end guides 60 are mounted on arms 61 which are adjustably secured to a cross-bar 62 by means of screws 63. Upon loosening these screws the arms 61 may be moved horizontally upon the bar 62, so as to be adjusted to hold and receive labels of different lengths. The crossbar 62 is mounted upon forwardly-extending horizontal rods 64 fixed on the yoke 44. By moving the cross-bar 62 forwardly or rearwardly on the rods 64 the position in which the neck label is applied to the bottle may be adjusted,

The neck-label holder is provided with a follower 66 which is controlled by a pawl mechanism comprising pawls 67 and rods 68 similar in function and construction to pawls 57 and rods 55 hereinbefore described. The label pickers 12 operate upon the neck labels 10 in the same manner that the label pickers 11 operate upon the body labels 9.

The label holders are filled by inserting the labels through the open bottoms of the holders, and to facilitate this operation the label holders are arranged to be inverted so that the labels may be dropped into them. For this purpose the yoke 44 is pivoted upon a stem 71 projecting forwa'i'dly from a head 76. The yoke is normally prevented from turning on the stem by means of a tongueand-slot connection 69 between the yoke and the head, and by a set screw which engages the stem and which is provided with a head 72 by which it may be turned. Vhen it is desired to invert the label holder the set screw is loosened and the yoke is drawn forward on the stem to disengage the tongueand-slot connection. When the label holders are so inverted the followers are depressed by manipulating the pawls to dis-' engage them from the toothed rods, and the label holders may then be conveniently filled with labels.

In adjusting or repairing the machine it is frequently convenient to move the label holders from their position above the other parts of the machine, and to permit this to be done readily without removing the label holders entirely from the machine the head 76 is pivotally mounted upon a pin 73 fixed in the frame of the machine. on the head normally engages a lug 75 on the frame to support the label holders in horizontal position. To prevent the label holders from being pushed upwardly by the action of the label pickers the head 76 is provided with an upper shoulder which normally engages an abutment 77 pivotally mounted upon a pin 78 on the frame of the machine. A sliding spring-pressed latch 79 in the abutment engages a recess in the shoulder on the head 76 and maintains the abutment in engagement with the shoulder. By means of a laterally-projecting pin 80 the latch 79 may be retracted and the abutment 77 may then be swung back and out of engagement with the shoulder on the head 7 6 to permit the label holders and their supporting mechanisms to be swung upwardly and away from the parts below. The label holders are supported in raised position by a stop pin 81 engaged by the shoulder on the head 76.

After the labels have been laid across the upper surface of the bottle by the label pickers they are temporarily held in place by the clamp 13. This clamp is provided with a central bottle-engaging portion 82 of A shoulder 74 rubber or other flexible material and is formed to engage both the body and the neck of the bottle. The clamp 13 is slotted on its upper surface to engage a lever 83 upon which the clamp is supported, and the clamp and lever are connected by a pin 85 loosely engaging an opening in the lever and secured therein by a cotter pin, as shown in Fig. 3. Springs 84 are provided between the clamp and lever to permit the clamp to yield slightly when in engagement with the bottle. The rear end of the lever 83 is supported by a block 86 secured to the frame of the machine, the lever being provided with a longitudinal slot to permit it to be thrown forward and back on said block 86.

The clamp lever 83 and clamp are actuated by a bell-crank lever 87 which is pivoted at one end to the lever 83 and is pivotally mounted at 88 on the frame of the machine. The other arm of the bell-crank lever is connected by a link 89 with a lever 90 pivoted upon the frame of the machine, and the lever 90 is connected by a link 91 with a slide 92 moving vertically in a guideway on the frame of the machine. The slide 92 carries a cam roll 93 which engages a cam path in a cam 94 mounted upon, and actuated by the power shaft 95 of the machine. A spring 40, engaging the slide 92, tends to move the slide downwardly to assist the clamping operation of the clamp. By the operation of the cam 9i and the mechanism above described the clamp lever is moved first forwardly and then downwardly at its forward end, at the proper point of the cycle of operation of the machine, so as to carry the clamp first forwardly and into position over the bottle, and then down wardly into engagement with the bottle.

The movement of the cam 9-1 and the power shaft 95 is not continuous, but these parts are thrown into operation intermittently upon the introduction of each bottle into the machine. The shaft 95 is actuated by a pulley 90 which may be belted to any suitable source of power. The pulley is journaled loosely upon the rear extremity of the shaft 95 and normally runs freely thereon, but by means of a one-rotation clutch the pulley is caused to impart a single rotation to the power shaft at each operation of the machine. The driving member of the clutch comprises a ring 98 fixed within a recess in the hub 97 of the pulley. The driven member 99 of the clutch is fixed to the shaft 95 and provided with inclined surfaces as shown in Fig. 7. These inclined surfaces constitute seats for rolls 100 interposed between the driving ring 98 and the clutch member 99 and when the rolls .are wedged between their inclined seats and the inner surface of the driving ring, the two members of the clutch are locked together and theshaft 95 is turned with the pulley 96. The rolls 100 do not bind the clutch members together, however, unless they are wedged in as first stated, and when not so wedged the pulley 96 runs wild. The position of the rolls with respect to the clutch member 99, .that is, the location of the rolls 011 their inclined seats is governed by a tightening ring 101 loosely mounted on the shaft 95 and provided with a plurality of fingers 102 which project rearwardly from the ring into the spaces between the rolls, so as to engage the rolls. WVhen the tightening ring 101 is turned on the shaft 95 the fingers 102 move the rolls 100 into or out of operative position as the case may be. As a' very slight movement only of the tightening ring 101 is necessary, a helical spring 121, having one end secured to the shaft 95 and the other end to the ring 101 is mounted between the shaft and ring and this spring operates to maintain the ring 101 in such position with relation to the shaft 95, and the clutch member 99, that the rolls 100 are in operative position and the clutch members locked together. The ring 101 is provided with a cam 103 which normally engages a detent 104 mounted upon a rod 105 which slides horizontally in the frame of the machine. So long as the lug 103 engages the detent 104 the ring cannot operate, and the rolls are thus detained by the fingers102 and prevented from operatively engaging the clutch members. Then the retaining ring is released by disengagement from the detent, the spring 121 returns to its normal position and turns the tightening ring 101 on the shaft 95 and thereby the clutch is thrown into operation and continues operative until the retaining ring makes a complete rotation and is again arrested by the detent, when the shaft turns a short distance with relation to the tightening ring, compressing the spring 121 and throwing out the rolls.

The clutch detent is controlled by the bottle gage 15 hereinbefore described. The bottle gage is mounted upon the forward end of a horizontal sliding rod 107 which is pivotally connected, by means of a grooved collar. 108, with the upper end of a lever 109. The lever 109 is pivoted at 110.upon the frame of the machine and its lower extremity is pivotally connected with the clutch detent. A spring 106 normally thrusts the detent rearwardly into operative position. hen a bottle is placed in the bottle rest and is pushed rearwardly against the gage 13, the gage is moved rearwardly, and, through the connection above described, the detent is moved forwardly out of engagement with the lug on the clutch retainer. After the labels have been afiixed to the bottle, and before the clutch has completed its revolution, the operator withdraws the bottle from the bottle gage, thereby permitting the spring 106 to return the parts to their normal position so as to interrupt the operation of the clutch until another bottle has been placed upon the bottle rest.

The wipers 1 1 are provided with bottleengaging extremities 59 of soft rubber or other flexible material, formed to engage both the body and neck of the bottle. The wipers are mounted upon upwardly-extending arms 111 mounted upon the forward ends of horizontal rock shafts 112. The rock shafts are mounted at the upper extremities of a yoke 113 which is carried upon two vertical guide rods 114 moving in guides 115 on the frame of the machine. The yoke 113 is raised and lowered to actuate the wipers by means of a connecting rod 116 which connects the yoke with a crank pin on the cam 94:, so that at each rotation of the cam the wipers are raised above the bottle and are then lowered to cause them to engage the bottle and the labels thereon.

During the upward movement of the wipers they are separated to hold them out of engagement with the bottle, and provision is made for moving them inwardly during the first part of the downward movement to bring them into operative engagement with the bottle. T c this end arms 118 are fixed upon the rear ends of the rock shafts 112 and these arms carry pairs of cam rolls 119 engaging opposite sides of cam surfaces 120. The cam surfaces 120 are formed integral with, and extend upers ascend to engage the labels in the label holders, and this relative movement causes the arms 118 to be actuated by the cam surfaces 120 so as to swing the wipersinwardly over'the bottle, and during their continued descent the wipers engage the labels at each side of the clamp and press the extremities of the labels smoothly against the bottle,

thereby completing the labelingoperation.

The above-described arrangement for moving the wipers and pickers in opposite directions at the same time secures mechanical balance between the mechanisms by which these parts are actuated, thereby conducing to the smooth operation of the machine and permitting the machine to operate rapidly without excessive vibration.
