ATTORNEYQ C'HHRLE QMHXWEL Patented Oct. 22, 1935 UNITED STATES PATENT OFFICE BAND, STAMP, OR LABEL MAGAZINE AND HANDLING MECHANISM Application May 2, 1933, Serial No. 669,062

13 Claims.

My present invention relates generally to banding, stamping or labeling machines and more particularly to a novel construction of magazine adapted for use in connection with such machines, to hold a stack of the bands, stamps or labels to be applied one at a time to the article to be stamped or banded, and this application is a continuation in part of my co-pending application, Serial #619,l60, filed June 24, 1932.

A prime object of the invention is to provide a magazine of the kind referred to and into the top of which successive supplies of the bands, stamps or labels may be fed without stopping the operation of the machine, and also from the top of which the labels may be selectedand removed, one at a time, for application to the article or object to be banded, stamped or labeled. So far as I am aware, I am the first in the art to provide a magazine, the construction of which is such that the bands or labels may be fed into and removed from the top thereof.

In all prior magazines with which I am fav miliar provision is made for selecting and removing the bands or labels either from the top or the bottom of the magazine. When removal is from the top the supply of bands is fed up thru the bottom of the magazine, and when removed from the bottom they are fed into the top of the magazine. Both types are open to objections.

Another object of the invention is to provide a magazine into which the bands, stamps or labels may be placed with the printed face positioned downward and from which they may be individually selected and removed in a horizontal plane with the printed face positioned upward, or vice versa, the construction being such that the bands or labels will be turned or reversed during their travel thru the magazine.

Another object of the invention is to provide a magazine of the type referred to that may be readily adjusted to receive bands, stamps, or labels of diiferent lengths or widths.

The above and other objects are accomplished by constructing the magazine witha substantially U-shaped channel to receive a stack of the bands, stamps or labels, successive supplies of which may be fed into the "down-leg of the channel and into the "up-leg of which a portion of the stack will always extend, so that the successively exposed top labels or bands in said up-leg may be removed one at a time to be transported by suitable mechanism to the article or object to which they are to be applied.

In order to enable others to understand, construct and use my said invention I will now proceed to describe the same in detail, reference being had for this purpose to the accompanying drawings, wherein,-

Fig. 9 is a side elevation, partly in section, of a modified form of the magazine, which is made adjustable to accommodate bands, stamps or labels of various lengths and widths; said view taken on the line 99 of Fig. 10; 25

Fig. 10 is a top plan View;

Fig. 11 is an end elevation of the form of magazine shown in Figs. 9 and 10; and

Figs. 12 and 13 are perspective views of the interchangeable fillers employed in connection 30 with the form of the invention illustrated in Figs. 9 and 10;

In the embodiment of the invention as illustrated, the magazine is shown attached to a bed-plate I, of a banding, stamping or labeling 35 machine and for convenience I shall hereafter refer to the magazine as a band magazine, but I wish it to be understood that the word. band is used in its broader sense to include a stamp or a label without regard to its size, the magazine here shown being designed for use in connection with a machine for applying fbands to articles or objects, such as a cigar.

The magazine shown in Figs. 1, 2 and 3 is made in the form of a generally U-shaped cast- 45 ing 2, the opposite side members 3 of which are provided with a band-receiving channel 4, which channel is of U-shape to receive a stack of bands 5, which are fed into the down-leg 6, and which extends around the bend or curve of the U and 59 up into the up-leg 1, thereof, and from which the uppermost bands in said up-leg may be successively removed by suitable gripper mechanism as hereinafter described. The lower portion or bend 8 of the U is preferably curved as shown, 55

so that a stack of labels located in the U-shaped channel of the magazine may move freely therethru as they are removed from the "up-leg, and to enable the magazine to carry a substantial supply of bands, I prefer to construct the down-leg 6 longer than the up-leg 1. This additional length is provided by attaching to the upper end of the down-leg6 a magazine extension 9 having oppositely disposed channels in its sides corresponding to and forming a continuation of the channel 4 in the magazine proper.

The casting 2, which carries the U-shaped channel, is provided with horizontal and vertical webs l0 and I2, the web l0 being provided with a cut-away portion forminga shoulder l3, and a flat face M to fit up against the bottom and an end of the bed-plate l, the magazine being attached thereto by suitable bolts l5 passing therethru and into the web Ill, depending from the bedplate, as more clearly shown in Figs. 1 and -2.

I prefer to provide the bottom or curved portion of the magazine 8 with a slot or opening, as shown in Figs. 1 and 3, to expose the lower edge of the stack of bands, for a purpose presently to be described.

In attaching the magazine to a banding, stamping or labeling machine, the down-leg of the magazine may be convenien'tly arranged at one side of the machine to position the open mouth thereof so that successive supplies of the bands may be easily inserted in the band channel, whereas the open end or mouth of the upleg 1 may be positioned close to the bed of the machine so that the uppermost band will lie in a substantially horizontal plane, and may be selected and removed therefrom to be positioned upon or across the article or object to be banded or labeled. If the bands are to be applied over the top of the article to be banded, then the stack of bands will be inserted into, the down-leg of the magazine with the printed faces of the bands positioned downward, so that in passing from the down-leg thru the U-bend into the up-leg the bands will be turned or reversed so that at the mouth end 'of the up-leg of the magazine they will appear with the printed face upward; and conversely, if the bands are to be positioned beneath the article or object to be banded, then they will be fed into the down-leg of the magazine with their printed faces upward, so that the unprinted face will appear at the mouth or delivery end of the up-leg.

Ordinarily, the weight of the stack of bands in the down-leg 6 of the channel and its extension 9 is sufiicient to cause the stack to be fed freely 'thru the band channel, so as to always keep the bring about proper feeding of the stack, I may add an additional removable weight l6, by positioning the same upon the upper end of the stack located in the down-leg, as more clearly shown in Figs. '1 and 3.

The lower end of the magazine 9 is preferably provided with laterally-extending flanges H which may be'positio'ned upon and secured by screws l8 to corresponding flanges I9, projecting outwardly from the upper end of the U-bend of the magazine where it joins the down-leg, as more clearly shown in Fig. 3.

I prefer to provide the open mouth of the up- 1egl of the magazine with a pointed member,

such as a blade 20, the sharpened point of which overlies one end of the band channel and is positioned to engage the upper band of the stack so as to retain it in position until it is engaged by a suitable band transporting device, such as the gripper mechanism shown in Fig. 8. 5

Any suitable mechanism may be employed for lifting the bands from the mouth of the up-leg" 1 of the magazine to permit them to be taken by the transporting mechanism to the point where they are to be applied to or about the 0b- 10 ject or article to be banded. In the present invalve-controlled cut-off mechanism interposed between the suction box 2| and the suction-creating means 24, said valve-controlled means consisting of a hollow casing 25, which may be opened .25 and closed to the atmosphere by a valve 26 mounted upon an arm 21, one end of which carries a roller 28 against which the periphery of the cain 29 moves to move the valve to and from its seat at properly-timed intervals. I The arm 2'! .30 is pivoted at 30,-and one end of said arm may be moved downwardly to open the valve 26 manually by depressing the hand-controlled rod 3|, the end 32 of which is disposed adjacent the bed I of the machine as shown in Fig. 1, where it will be as accessible to theoperator so that if at any time it is desired to throw the suction picker out of commission this may be readily accomplished manually and independently of the automatic opcrating means. 40

The lower end of the tube 23 is connected to the valve-casing 25and a separate pipe 33 leads from said casing to the suction apparatus 24.

As more clearly shown in Figs. 5 and 6, the suction box 2| is provided at one side with a boss 34 5 having a vertically-extending opening 35 thru which a fixed stem 35 passes and upon which it I may slide. 'Theboss fl hasan outwardly-extending stem or screw '35" which is engaged by the fork of an arm secured to and projecting lat- 50 erally from a rock-shaft =31, so that when said shaft is rocked in one direction or the other, it

will cause the suction box H to move into and out of contact with the uppermost label of the stack in the up-leg of the magazine to lift the band into position to be gripped by the grippers of the transporting mechanism, as more clearly shown in Fig. 8. The rock-shaft 31 is normally urged in an anti-clockwise direction by means of a coil spring '38, the upper end of which 00 bears'upon the block 39 secured to the-rock-shaft. The block has-atail piece 40 mm which a screw 4| passes to 'li'mit'the movement of the rock-shaft in one direction or against the action of the spring 38. The rock-shaft 31 carries an arm 42 .posi- 55 tioned to be engaged by the end of a corresponding arm-lamented upon a vertically-reciprocatin'g rod 4'! (see Fig. 7). The lower end of the rod is pivotally'connected to-a pivoted arm '45 having aroller 46 adapted to 'be engaged by a cam 7 "47 so that the rod 44 is given regularly-timed reciprocating movements to properly operate the suction-picker '21 and thus lift the bands-successively from the mouth of 'themagazine. When 50 lifted a free endof each band will be in a posi- 7,

tion to be readily grasped between the gripper mechanism consisting of fixed and movable gripper jaws 4B and 49, which jaws are mounted upon a horizontally reciprocating carriage 50, which carriage may be moved back and forth by any suitable mechanism such as the rack and segment shown in Fig. 8. The gripper jaws are closed and opened at suitable intervals to grip and release the bands by any preferred mechanism such as the mechanism shown and described in my copen-ding application, Serial #619,160, flied, June 24, 1932.

In Figs. 9, and 11, I have shown my improved magazine constructed to accommodate bands, stamps or labels of different lengths and widths, and according to this form of the invention the opposed U-shaped banding channels which receive the ends of the stack of bands, or the like, are formed in separate opposing plates or castings 55, each of which has a laterally projecting bracket 55 having a slot 51 thru which an attaching bolt 58 passes, whereby the said plates or castings 55 may be adjusted laterally toward and from each other thru the medium of the bolt and slot connections. The plates or castings are further joined together by means of transverse bolts 59, and interchangeable filler or spacer blocks or washers 60 are located between the companion plates or castings and fitted over the bolts 59, as more clearly shown in Figs. 10 and 11.

The down-leg" oi the band channel in this construction is, like the constructions previously described, formed with an upward extension 6! to receive an extra supply of bands, said upward extension being formed by two opposed channel castings iii, the lower end of each or which is provided with a laterally extending flange 62 provided with a slot 53 thru which a bolt 64 passes, the lower end of the bolt having a threaded connection with a laterally extending flange 65 carried by the upper end of the down-leg of each casting 55 and upon which the lower end of the extension member 5i rests. Obviously, said extension members 5! may be adjusted toward and from each other thru the medium of the bolt and slot connections to accommodate bands of different lengths.

In order to accommodate bands of difierent widths, I may provide the channel members 55 and iii with removable and interchangeable channel members 56 and 58, as shown in Figs. 12 and 13. Each channel member 66 illustrated in Fig. 13 is substantially U-shaped and is provided-with a channel 6Twhich is narrower than the channel normally provided in the plates or castings 55, but may be removably inserted therein, it being understood that one such member 66 will be located in each of the channel plates or castings 55.

Similarly, said channel blocks 68 will beremovably inserted in the channels of the extensions 6|, one in each extension, and when assembled the lower end of the channel block 68 will rest upon the upper end of the down-leg of the U-shaped channel 55 so that a continuous channel will be provided. The removable channel members referred to may be held in position in any suitable way, as by the screws 69, and obviously, the channel castings 55 and 6! may be initially provided with channels of extra width to receive any one of a number of interchangeable channel members B6 and 58, so that when bands, stamps or labels of different size are to be used in the machine, it is only necessary to select the appropriate interchangeable channel members to accommodate the selected labels. While it is possible to accommodate a fairly wide range of label sizes with the arrangement above described, it will be obvious of course that the construction has its limitations and for this reason it may become necessary,--where bands or labels of an extra 5 large size are employed, to likewise have U-shaped and channel extension members 55 and 61 or different widths.

In both types of magazine shown and described, the lower edge of the stack of bands 10 located in the curved portion of the magazine is exposed, as more clearly shown in Fig. 1, and in order to resist backward or reverse movement of the stack when the suction picker 2| makes contact with and presses upon the stack at the delivery end, I provide a stack-holding means, which, in the instance shown, consists of a flexible strap 69 of metal or other material, one end of which is attached to a pivoted ball 10, the ends of which are sprung into seats formed in the outer faces of the sides of the magazine. The other end of the strap 69 is pivotally connected to an arm H mounted upon the end of a vertically-reciprocating rod 12. The lower end of the rod 12 is connected to a lever 13, pivoted at I4, and the free end of said lever is provided with a roller 15 which rides over a rotating cam 16 mounted upon a driven shaft H. When in normal position as shown in Fig. 1, strap 69 is adjacent but out of contact with the edge of the band stack. It is brought into contact with the edge of the band stack immediately the rod I2 is moved upwardly, as when the suction picker H is brought into contact with the uppermost band of the stack located at the mouth or the upleg oi the magazine. The construction and arrangement of the parts is such that whenever the suction picker 2| is moved down upon the stack of bands 5, in the up-leg" of the magazine channel, the flexible strap 69 will have been moved by the mechanism described, into contact with the exposed lower edge of the stack of bands to hold the stack from reverse or backward movement in the magazine channel, and immediately the suction picker is raised from the stack, the strap 69 will be moved away from the edge of the stack to permit free forward movement of the stack thru the channel.

It will be understood of course that in order to permit the bands to feed by gravity thru the U-shaped channel, they must fit iairly loosely therein, so that the stack may feed freely, and because of this, there is a tendency oi the suction picker when it makes contact with the upper end of the stack, to push the stack backward or reversely thru the channel. To prevent this the flexible strap 69 is provided, and this serves as a check or stop for the stack. The cam 16 which operates the rod 12 and thru which the flexible strap 69 is actuated is so timed with relation to the upward and downward movements of the suction picker 2| that the strap 69 will make contact with the edge 01' the stack of bands just prior to the time that the suction picker makes contact with the upper end of the stack, and said strap will be moved out of contact with the band stack immediately the suction picker begins to rise.

While I have herein shown and described 7 preferred embodiments of the invention, I do not wish to be understood as limiting myself to the specific construction shown, except as I may be limited by the terms of the appended claims, as further modifications will obviously suggest them- 15 selves to those skilled in the art, without departing from the spirit of the invention.
