' Application tiled January I3, 1891. Serial No. 377,656. (No model.)
To all whom it may concern:
Be it known that I, HENRY ALBERT, a citizen of the United States, residing at Crescent City, Del Norte county, State of California,
have invented an Improvement in Can-Labeling Machines; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to the general class of ro can-labeling machines, and especially to machines of this class in which a reciprocating cau-puller and pasting mechanism operates within a runway, as exemplified in the machine shown and described in my patent, No. i5 445,418, granted January 27, 180i. y
My invention consists in certain improvements upon my former machine, and the novel constructions, combinations, and arrangements hereinafter fully described, and zo specifically pointed out in the claims.
The general object of my invention' is to provide a simple and eifective machine for labeling cans, and which can be readily adjusted to suit the requirements of different sizes of cans.
Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my machine. Fig. 2 is a vertical lon gitndinal Section of same. Fig. 3 is a cross-section in .the plane of the paste-platens and an elevation of the locks. Fig. et are plan views showing the lock and the mechanism thereof. Fig. 5 is an elevation of the interior of one side of the runway and one side of the can-puller. Fig. 6 is a section of the paste-receptacle shown on frame B and a small perspective view of one end of the paste-rolls. Fig. 7 is a plan of frame B. Fig. 8 is across-section 4o of the4 frame A, pieces X, and can-runway.
Fig. 8* is a detail shownig the controlling device.
A is the frame of the machine having a runway a on its top. Vithin this runway is adapted to be reciprocated a frame. B, which carries the paste-containing vessel C and which has hinged to its front portion the canpuller D. The frame BY is mounted in the runway by means of outwardly-extending 5o slide-pins b, which fit and move freely 1n extended slots or tracks a in the sides of the runway. Its movement is effected by the foilowing mechanism:
E is a shaft having on one or both ends suitable driving mechanism-such as a crank or crank-wheel, fly-wheel, or belt-pulley-and at its center a crank e.
F is a rod upon which are freely swung or pivoted the angle-levers f, the long arms of which extend downwardly and are formed 6c int-o forks f', which embrace and play in bearings in the outer ends of arms b', connected with the slide-pinsof the frame B. Between the downwardly-extending or longer arms of the angle-levers f is a rod f2, from .which a connecting-rod e extends to the -crank c of shaft E. Now by rotating shaft E 'the frame B will be reciprocated in the runway, and its stroke may be varied by making lthe cross-rod f2 adjustable in the swinging 7 leversf, as is shown, by fitting its ends in lelongated slots f3 therein.
The receptacle C for the paste consists of a lsuitable vessel, which is mounted upon the vframe B in any proper manner.
IVithin this receptacle is a lower roller c and an upper roller c', both of said rollers being mounted transversely of the vessel and in end grooves or slides, whereby they can be readily removed 'and may rest in perfect contact with each 8c other.
The upper roller c is formed with a grooved periphery, as shown, the grooves extending circumferentially and throughout the v entire length ot' the roller. A scraper c2 acts upon the upper roller c to remove t-he surplus paste.
The can-puller D consists of two side plates havin g rearwardly-extending arms, which are pivoted to the forward end of the frame, as shown. Between these plates is carried the 9o top pressure-roller (l, the ends of which are mounted in sliding boxes CZ, held down by springs cl2, whereby said roller is enabled to exert a pressure upon the top of the can and at the same time yield to any inequalities in the surface upon which it bears. The sliding boxes are themselves mounted in adjustable bearings or blocks cl3, mounted in the sides and adjusted by means of screws (Z4, whereby the primary position of the .pressure-roller roo can be determined. Upon the inner surface of the side plates of the can-puller are the small rollers d5, which, when the puller-frame is dropped down upon the can, bear on said can near each end and roll and guide it along. These small rollers are rendered adjustable to-suit dierent sizes of cans by being carried on movable blocks d, operated by screws d?, and they are arranged diagonally or converging downwardly. This inclined position is of advantage, because in etlecting the change in position or adjustment of the rollers they will bear properly upon any.sized can and keep it in the center of the canpnller under the pressure-roller.
As in my former machine, it is intended that the can-puller in advancing toward the can shall rise to a higher plane in order to drop down upon the can and to avoid the triggers of the locks, and shall then pull the can forwardly in the machine, and to this end the construction of the runway is substantially similar to that shown in my former machine. A brief description, therefore, will only be needed for my present application.
The can-puller is provided on each side with rollers which travel in the track-grooves or slots a of the runway. In the sides of the runway are the upper track-grooves a3. Near one end these grooves communicate by a switch-bar d, one on each side and pivoted at a, so that they mayswing. The lower end of the switch-bar lies normally upon the lower track-groove a', its point being flush therewith, while its upper end extends beyond its pivot and rises above the level of the upper track-groove. At their other ends the two track-grooves communicate by a groove a6. Now when the can-puller is moving toward the can its rollers d* travel in the lower grooves a until they reach the switch-bars a". TheyT then travel up on these switch-bars and reach the level of the upper track-grooves a3, thereby swin ging the whole can-pullertoa plane higher than that in which the can itself lies. The rollers d4, passing the pivotal point a5 of the switch-bars, travel upon the upper extended end of said bars, and thereby raise their lower ends from the lower track grooves, thus opening said grooves for the passage of the slide bars or pins of the following frame B,
and even though the rollers d4 pass off of.
the extensions of the switch-bars said bars do not drop down :immediately to their normal position, as their lower ends are held up by means of supporting-bars b2 on the sides ot' the frame .13, so that said frame passes in the lower track-grooves without interference from the switch-bars. As soon as the frame is passed the switch bars drop down to their normal position. W hen the can-puller reaches the can, its rollers (Z4 drop down through the communicating grooves a into the lower track-grooves, and thus the canpuller drops down upon the can, its small rollers diitting in front and behind it at each end and the top roller pressing upon it, thereby fully insuring its rolling action. On the return stroke the frame B and can-puller travel in the lower trackgrooves, rolling the can along.
G is an inclined feedchannel for the cans, by which they are successively directed into the feed end of the runway In this end of the runway is the controlling device for feeding the cans one at a time. This consists of a swinging frame H, controlled by an under lying spring h. In the top of this frame is fitted adj ustably a bent stop-arm h,which can be moved and set forward or back to suit the requirements of different cans. This is accomplished by mounting it in its trame, so that it can slide, and setting it by a screw. In its normal position the spring holds the bent arm up directly in the path of the can, which in this position lies exactly under the point at which the can-puller descends upon it, and when the can-puller engages it it sirnply pulls the can forward, therebydepressing the spring-controlled stop-arm, which allows' the can to pass over it, but immediately springs up again to limit and stop the next can.
I is the label-box extending downwardly directly under the runway of the machine,its top being open and communicating therewith. In the box is a vertically-movable bottom fi, which carries the pile of labels. The bottom is held up, with its pile of labels, to proper place for the reception by the uppermost label of the paste by means of the weight W acting on the stem t" of the bottom by means of a cord and pulleys, as shown, and in a similar manner to the device shown in my previous machine.
Now, in order to form a stop for the labelpile to hold them exactly in the place desired and yet relieve the topmost one, I have the following locks or holders: l
.I are the locks or holders, consisting of bars extending into the runway from each side and projecting over the top of the label-pile. There are four or' more of these, ltwo being shown near each end,one at each side of the label-pile. They are carried each in a frame j, having end guides j', in which said lockingbars are adapted to have both an up-anddown movement and a forward-and-back movement. In the framej is mounted vertically a shaft j2, controlled by a spring jl, the lower end of this shaft passing through an elongated slot j in the locking-bars, whereby said bars have their movement uninterfered with by the shaft. Upon the shaft is carried a cam j, which engages the locking-bars by means of fitting its eccentric rim in guidesj, provided with anti-frictional rolls. This cam is so fashioned that its first effect upon being rotated is to raise the locking-bar bodily and its next eifect is to move it longitudinally. The cam-shafts are operated by means of trigger-bars jl, pivoted to the top of the frame and having their inner ends extended into the path of travel of the can-puller sides. These triggers have their outer ends formed with or provided with toothed segments j, which engage with corresponding tooth disks or pinions j on the cam-shafts. The operation of these locks or holds is as follows: Normally the locking-bars .I overlap and hold The supporting-bar is provided with a guide- Ato be given to the platens.
down the label-pile. Now when the canpuller is moving forward with a can the forward ends of the sides of the can-puller first come in contact with the trigger-bars of the first pair of locks, thereby operating the cams and effecting first the elevation of the locking-bars and then their withdrawal, so that that end of the'label-pile is relieved, and at this moment the can reaches the end of the label-pile and picks up the end of the topmost label. As soon as the trggenbars Aare relieved by the sides of the can-puller the springs ji return the first pair of locks to position upon the next label. The can-puller then comes in contact with the trigger-bars of the second pair of locks and operates them in the same way, and upon being relieved the locking-bars return and hold that end of the label-pile. The object of the rising movement of the locking-bars is to carry them to a plane sufficiently high to insure their return upon the labels without danger of catching the edges of the label-pile. These locking mechanisms being carried wholly by the frames j, enables me to readily adjust their position to suit different lengths of labels. This is accomplished by bolting the frames in elongated slots, as shown, whereby they can be moved to different positions.
^ The labels are supplied with paste by the following means: O are pasting-heads. There are two of these, one at each end of a-supporting-bar 0, and they lie directly'- over and transversely of the ends of the label-pile.
stem 0', extending upwardly through a suitable guide 02, carried by a frame 03, and having a lifting-spring 04 about its upper end. The pasting-heads are depressed by means of the lever P, pivoted to an arm of the rod E and connected 'by a rod p with a cross-rod p,- extending between the shortarms of the levers f. Now by the operation of the shaft E the pasting-heads are depressed and are allowed to rise under the power of the spring. The time of this movement is such that just after the can puller has rolled its can over. the label-pile the platens begin their descentv` until they press upon the ends of the topmostA label and supply said ends with paste. Then, as the can-puller returns the pasting-heads rise out of the way of the pressure-roller of the can-puller, which passes under them while the can-puller sides pass on each side. The amount of pressure of t-he pasting-heads upon4 the vlabel ends is nicely regulated and varied by making an adjustable connection between the lever P and the connecting-rod p. The rodpasses through a rocking bearing p2 in the lever and has upon its lower end a nut p3, which, by being set up or down, effects the contact with the lever at different times, thereby providing for varying the pressure This same result can be effected by rendering the cross-rod p adjustable, as shown, in the short arms of the levers j'. Upon the end of the lever P is the counterbalance-weight XV', the object of which is to balance the platens and their connected parts, and thus permit the use of a comparatively light spring for the purpose of raising the platens.
The pasting-heads are supplied with paste bythe contact with their under surfaces of the upper paste-roller c in the 'paste-receptacle..
The upper limit of movement of the pasting-heads is such that the paste-roller passes forward and back directly under and in contact with their under surfaces. f'
Although the upper roller c in the pastereceptacle might have a smooth surface, there is an advantage in forming it with a grooved surface, as described, in that it is not only better supplied itself with paste from the lower roller, but also better transfers the paste to the under surface of the pastingheads in anumber of tine parallel lines, which furnish a sufiicient quantity, and Which, when pressed down upon the label, spread out to provide just enough, thereby avoiding the squeezing out of the paste. l
The action of the pasting-head on the label ends is peculiar and of great advantage. When the pasting-head comes down upon the end of the label, it supplies it with paste, and then upon rising from said end the label adheres to the pasting-head; but as the lockbars hold the label down the free end must describe a short arc of a circle in attempting to follow the pasting-head, so that the end rubs or draws over the surface of the pastinghead in the manner of a brush, and has its paste more perfectly spread and also distributed to the very edge of the label. It is not essential, therefore, that the pasting-head shall come in contact with the label in the iirst instance at its very end, and by being removed slightly therefrom avoids any lia` bility of putting any paste upon thel next label below.
Q is a discharge-chute for the cans. A t the end of the cam-ledge a2, just before reaching the discharge-chute, I have a slight inclined plane di, the object of which is to raise the can at that point under the pressure-roller, thereby producing a slightly-increased pressure, which, as it takes place over the lap of the label, is of advantage in insuring the proper adhesion of said lap. v
On each end of the movable bottom 'L' of the label-box is placed the inclined plane t2, the object of which is to raise the ends of the label a little, for two purposes-namely, to better insure the pressure of the pastingheads and so getting the paste upon them and the placing of the label ends in proper position to be picked up by the body of the can without interference by the raised portions or 'beads formed by the heads of the can.
l have adapted Ylny present machine to pro vide for different sizes of cans by means of adjustments to be given to all the parts which may require them for this purpose. The first IOO ITC
adjustment is naturally the variation in the width of the runway to provide for different sizes of cans. This adjustment is accomplished as follows: The runway is formed by side pieces, and these are carried by supportingpieces X, which areY mounted upon the frame A in such a manner that they can be moved to or from each other to vary the width of the runway. This movement is effected by means of the right and left hand screws at each end of the'machine connected by pinions a," with a longitudinal shaft m2, having a hand-wheel :113. The side pieces of the runway have a minor adjustment of their own on the supporting-pieces X by means of the slotted plates and screws Y, which provide accurately for the can-ledges a2. The frame 03, guiding the pasting-head stem o', is also adjustable b y the slots and thumb-screws, as shown, and the pasting-heads O are tted removably and ad justably upon the supporting-bar o by sliding thereon to provide for different lengths of labels and for the substitution of others for diiferent widths of labels. The locks being carried by the adjustable pieces X, move with said pieces, and as the sides of the can-puller move to or from each other it is only necessary to substitu te a different length of pressure-roller. The sides of Athe label-boxes are carried by the movable pieces X, and are thereby adjusted, 'and an* other bottom of suitable size is to be substituted when the box is varied.
The general operation of the machine may be thus brieflydescribed: The causare placed in the feed-chute G, and are stopped and relieved one by one by the bent arm h. Starting the machine the frame B and can-puller move back, and the latter rises to its upper plane. The paste-roller c passes under and supplies the elevated platens with paste. At the end of the stroke the can-puller drops upon the foremost can. On the forward movement the can is rolled along. The pasteroller again passes under the still elevated pasting-heads, and the can-puller following releases the locks. The can rolls upon the topmost label, the end of which has been previously supplied with paste, and picks up said label,which, as the can rolls,winds about said can and is pressed evenly by the pressureroller. The first pair of locks returns to hold the label-pile and the second pair is released, so that the can picks up the other pasted end of the label, which is now fully applied. Then the Second locks return and the pasting-heads now descend and apply paste to the ends of the next label and at once rise again. The labeled can is now discharged and the operation is repeated. The ends of the labels may be moistened in any suitable manner.
