WRAPPING-MACHINE.
Specication oi' Letters Patent.
Patented Oct. 1, 1912.
To all whom it may concern:
Be it known that I, GEORGE I. Hom., a citlzen of the. United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Wrapping-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to characters of re erence marked thereon, which form apart of this specification.
The present invention has reference, generally, to improvements in automatic wrappmg machines; and, the invention relates, more partlculariy, to a novel construction of apparatus, and the devices and parts thereof, by means of which numerous articles, such for example as chewing-gum, candy, soap, and the like, may be provided with suitable wrappers and labels.
The principal object of the present invention is to provide a novel and comparatively simple Wrapping machine, in the construction of which the devices and parts comprising the mechanism are comparatively few in number and simple in operation.
Furthermore, it is the object of the present invention to provide positive mechanism for making each Wrapplng fold or movement, together with means for carrying the article to be wrapped, independently of the movement of its fellows, through th'e various Wrapping or folding mechanism, thereby obviating the pushin or feeding of one article by another as as been the practice in machines of this character. Such an independent and positive feeding of the articles to be wrapped, as the present invention provides, enables the operator t0 remove improperly wrapped artlcles from the apparatus, at any stage of the wrapping operations, without impairing the Wrappmg operations with respect to any following or preceding article.
Another object of the present invention is to provide a novel mechanism for making the end-folds of the wrapper, the same being of a very simple construction and positive in action.
Other objects of the present invention not at this time more articularly enu` merated will be clearly understood from the following detailed description of the present invention.
With the various objects of the present invention in view, the same consists, primarily, in the novel Wra ping machine hereinafter set forth; and, urthermore, this invention consists in the novel arrangements and combinations of the various devices and parts, as Well as in the details of the construction of the same, all of which will be hereinafter more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to and which form an essential part of the specification.
The invention is clearly illustrated in the accompanying drawings, in whichz Figure l is an elevation of one side of the novel construction of wrapping machine made according to and embodying the principles of the present invention, and Fig.V 2 is a plan view of the same. Fig. 3 is a part plan view and art horizontal section of the details of t e various Wrapping mechanisms, the said view being drawn on an enlarged scale. Figs. 4, 5 and 6 are detail Acentral vertical longitudinal sect-ions illustrating various stages of the operation of the wrapping mechanisms and the devices for feeding or propelling the articles to be wrapped through the apparatus whereby the same are subjected to the operation of said wrapping mechanisms, these being also drawn upon an enlarged scale. Fig. 7 is a large detail transverse section taken on line 7--7 in said Fig. 4, illustrating articularly the mechanism for making t e end-folds of the Wrapping op-` eration, in this view the propelling means is shown in position ready to pass an article through sald end-fold wrapping mechanism. Fig. 8 is another large detail transverse section, taken on line 8-8 in said Fig. 4, illustrating particularl the mechanism for receiving the wrappe and labeled articles.
Similar Vcharacters of reference are employed in all of the said hereinabove described views, to indicate corresponding parts.
Referrin now to the several figures of the drawings, t e reference-character 1 indicates the complete apparatus showing one embodiment of the novel wrap infr machine, the same comprising a pair o si e-frames 2 5 extending transversely of said side-frames,
upon said platform 6,
said driving shaft 4 extending transversely of said side-frames. Said driving shaft 4 is provided at one end with any suitable construction of driving pulley 5. Supported 0 across the upper front portions of said sideframes, in any suitable manner, is a platform 6, the same being channeled to provide a guiding run-way for a reciprocating pushplate 7 supported thereon. The inner end of said platform 6 is provided, at a point beneath said push-plate 7, with alternated supporting members 8 and spaces 9, upon which the article to be wrapped is delivered in front of said push-plate 7. Supported and registering above the supporting members 8 thereof, is a feedchute 10, in which the articles to be wrapped are stacked. The means for producing the properly timed reciprocations of said pushplate 7 upon the platform 6 consists of the .following elements :-Journaled in the lower outer end-portions ofsaid side-frames, so as to extend transversely, is a rock-shaft 11 to which are secured upwardly extending arms 12 which are provided at their upper ends with forked portions 13 which operatively engage the transverse rod 14 secured in bracket-pieces 15 depending from the underside of said push-plate 7. Upon the rocking or oscillation of the said rock-shaft 11 and the arms 12, the said push-plate 7 reciprocates forwardly and backwardly in the channel or guide-way of said platform 6, the latter being provided with suitable spaces or cutaway portions 16 permitting the connecting link 18.
passage of said downwardly depending bracket-pieces 15. Secured to one end of said' rock-shaft 11 is a lever-arm 17, to the free end of which is pivotally connected a Secured upon one end of said driving shaft 4 is a crank-arm 19 which is provided adjacent to its free end with an outwardly extending push-stud 20. Rotatably mounted upon a screw 21, or other suitable support, which is arranged at the extreme end of said driving shaft 4 is a roller 22. The said connecting link 18 is provided with forked end-portion 23 which straddles said roller 22, being retained thereon by means of the washer 34. Secured upon the inner face of said connecting link 18 are a pair of cam- portions 24 and 25, the said cam-portion 24 being engaged by said ush-stud 20, when said crank-arm 19 is rotated by the said driving shaft 4, so as to push the said connecting link 18 in one direction and causing a corresponding oscillation of the rock-shaft 11 and arms 12. Upon the continuation yof the rotation of said crank-arm 19, said push-stud engages saidl cam-portion 25, and pushes said connecting link 18 in an opposite direction, causing a corresponding opposite oscillation of said rock-shaft 11 and its arms 12.
Journaled in bearings 26, which are arranged upon said side-frames 2, is a wrapping roll or cylinder 27, the same being provided with a transverse or diametrically disposed opening or slot 28 in which is slidably arranged a push device or element 29, which may be in the form of a push-plate or sliding bolt. Said Wrapping roll or cylinder 27 is arranged adjacent to the said feed-chute 10, with its opening or slot 28 normally in registration with the push-plate 7. Said wrapping roll or cylinder 27 is provided at one end with a gear-wheel 30 which meshes with an idler gear-wheel 31 mounted on a stud 32 projecting from one of said sideframes 2. Arranged to mesh with said idler gear-wheel 31 is an intermittent drive gearwheel 33, which is secured upon said driving shaft 4, and which being rotated therewith transmits a properly timed intermittent movement to said wrapping roll or cylinder, such movement being timed to provide. a
f half-revolution of said wrapping roll or cylinder to one complete revolution of said driving shaft 4. The reference-character 35 indicates bearings which are also arranged upon said side frames 2, and in which is journaled a label wrapping roll or cylinder 36, the same being provided with a transverse or diametrically disposed opening or slot 37 in which is slidably arranged a pushdevice or element 38, which may bein the form of la push-plate or sliding bolt. Said push device or element 38 is provided upon its opposite sides with projections or lugs 39 extending atright angles to the face thereof, the project-ions or lugs on one side being located at one longitudinal edge of said push device or element, and said projections or lugs on the opposite side being located at the opposite longitudinal edge of said push device or element. The opposite walls of said opening or slot 37 are provided with suitably ldisposed channels or grooves 40 in which the respective projections or lugs 39 of said push device or element ride. Said wrapping roll or cylinder 27 is provided at its opposite end with another gear wheel 41 which meshes with an idler gear wheel 42, which is mounted upon one of said sideframes 2. Said label wrapping roll or cylinder 36 is provided with a gear-wheel 43 which meshes with said idler gear 42, whereby when said wrapping roll or .cylinder 27 is intermittently rotated, a similarly timed and controlled intermittent rotation of said label wrapping roll 36 is produced by means of the gear connections with said wrapping roll or cylinder 27 above described.
The respective Wrapping rolls or cylinders 27 and 35 are each provided with properly` disposed longitudinally extending air-channels or passages 44, communication from which to the surface of the wrapping rolls or cylinders is had through the plurality of transverse ducts or perforations 45. Said air channels or passages 44 communicate with proper valve-mechanism contained in the valve-caps 46, and communication is also had with said valve-mechanism through proper channels leading to the exhaust caps 47, to which are connected the air exhaust pipes or conduits 48, the object being to provide a suction at the surface of said wrapping rolls or cylinders 27 and 35 adapted to piek up respectively the Wrapping paper 49 and labels 50 from the respective paper feeding mechanism 51 and label feeding mechanism 52, which are respectively located beneath the said wrapping rolls or cylinders 27 and 35, and are secured in such locations to said side frames 2, in any suitable manner. This manner of feeding wrapping paper and labels to the wrapping mechanisms has been described and claimed in detail in previous patents, and therefore I make no special claim thereto, or detailed description thereof, for the same will be readily understood by those skilled in the art to which my present invention is applied.
The reference-character 53 indicates the articles to be wrapped, the saire being stacked in the feed-chute 10,-with the bottom article resting upon said supporting members 8 of the platform 6, and in front of said push-plate 7. At either side of said push-plate 7 are forwardly projecting pushlingers 54 which project beyond the ends of the article to be wrapped as it lies in front of the said push-plate 7. The free ends of said push-fingers 54 are adapted to engage the opposite extremities of said push-device or element 29 arranged within the opening or slot 28 of said wrapping roll or cylinder 27, so that the forward movement of said push-plate 7 is transmitted to said push device or element 29. As the said wrapping roll or cylinder 27 makes its half revolution, it picks up a piece of said wrapping paper 49, which is thus presented across the mouth of the opening or slot 28 when said `wrapping roll or cylinder comes to a stop,
with said slot or opening in registration or alinement with the said bottom article in said feed chute 10. Subsequent to this positioning of the wrapping roll or cylinder and the wrapping paper, the said push-plate 7 is moved forward, carrying before it the article 53, which it pushes against the wrapping paper, thereby forcing both Wrapping paper and article into the said opening or slot 28, with the former folded partially about the latter. (See Fig. 5.) This being accomplished the said push-plate 7 is withdrawn until another article falls upon the supporting fingers 8 in front of the same. The said wrapping roll or cylinder 27 is now caused to make another half-revolution which carries over the article, in the manner illustrated in Fig. 6. The push-plate 7 again operates to insert another article and a piece of wrapping paper into the opening or slot 28, in the manner above described, and simultaneously the said push-fingersl 54 push forward through the slot or opening 28, said push device or element 29 which ejects the previously inserted article and its wrapping from said opening or slot 28 and beneath a folding-bar 55, which makes the last longitudinal fold of the wrapping paper about said article. It will be apparent that by virtue of the positive contact of said push-fingers 54 with said push device or element 29, the strain or force of ejecting one article through the medium of a newly inserted article is obviated, thus preventing the crushing, marring, or other injury of the articles to be wrapped, and often preventing the clogging or obstructing of the w rapping mechanism consequent upon such injuries to the article to be wrapped. The said folding-har 55 is pivotally secured upon one of said bearings 26, and extends transversely across the machine, and in alinement with, though slightly above the mouth of said opening or slot 28 of said wra ping roll or cylinder 27. The free end o said folding bar is retained by a suitable spring catch-member 56 secured to some suitable stationary part of the machine. When desired, said folding bar n'ay be released and thrown back out of the way to gain access to the article ejected from said wrapping roll 0r cylinder, if for any reason it may be desirable to remove the same. The longitudinal folds of the wrapping paper 49 about the article 53 having thus been made, the same is carried through an end folding mechanism which lies intermediately of said wrapping roll or cylinder 27 and said label Wrapping roll or cylinder 3G. Secured to said side-frames 2 are inwardly projecting folder-plates 57, the same registering in proper position and relation to the slot or o pening 28 and the slot or opening 37 of the respective wrapping rolls or cylinders 2T and 35. Each folder-plate 57 is provided with a cut-away'portion preventing an opening or hatch 58 through which the end folds of the Wrapper may be turned downwardly. Arranged in the forward end of each opening or hatch 58 is a creasing roller 59, th'- same being rotatably mounted upon a suitable stud 60. Arranged about each stud 60. between a portion of the folder plate and said creasing roller, isa coil-spring 61,which tends to maintain said creasing roller in proper position against the inner longitudinal edge of said opening or hatch 58. Said creasing roller is preferably arranged to register in position beneath said folding bar 55, with its periphery projecting slightly above the supporting surface of the folderplatc 57, so that as'the article with its wrapper passes` beneath said folding-bar, the ends of said wrapper ride over said creasing rollers, which tends to crease slightly the wrapper close to the ends of the article, whereby the ends of said wrapper will more easily fold downwardly when brought in contact with the end folding mechanism proper.
Secured upon the upper surface of each folder-plate is a guide-member 62, the same projecting upwardly, preferably at right angles to the supporting surface of the folder-plate. The forward end of said guide-member 62 extends forwardly over said opening or hatch 58, and is cut away along its bottom edge to provide a space 63 through which the end-fold of the wrapper may pass. Said guide-members 62 are spaced apart from each other a suiicient distance to permit of the article to be wrapped to pass lengthwise between the same, and the eXtreme forward end of each guidemember is rounded, as at 64, so as to guide the end folds of said wrapper into said spaces 623. Connected with said guide-members 62 is a fold-turning plate 65, the same forming an acute angle with relation to the forward end of said guide-members so that the respective forward ends of said foldturning plate and said guide-members are spaced apart from each other.
Each folder-plate 57 is provided with a turn under guide-portion 66 which is chamfered through the thickness of said folder plate 57, and which lies in an obliquely arranged slot or opening 67 formed in said folder-plate, and communicating with the inner rear end of said opening or hatch 58. The lower edge of said fold-turning plate 65 is inclined downwardly so as to meet the end of said' turn under guide port-ion 66, thus forming a guiding portion 68 which both turns downwardly the end fold of the wrapper, and at the same time guides it into-said turn under guide portion 66, as the article and its wrapper is passedthrongh said end fold mechanism. As the article to be wrapped, with its wrapper folded longitudinally around the same, is ejected from said wrapping roll or cylinder 27, so as to rest beneath said folding bar 55, a carrying or propelling means (to be subsequently described) propels the same through said end folding kmechanism, above described. By this means the article and its wrapper is moved rearwardly until the end folds of the wrapper slip beneath said guide-members 62 and into the spaces 63, being at the same time engaged by the guiding portions 68 of said fold-turning plates 65, which turn downwardly said end folds through the openings or hatches 58, and then guide the same into the slots or openings 67, and in operative contact with the turn under guide port-ions 66 wlnch are formed 1n said folder- Tplates 57. The said turn under guide portions 66 draw the said end-folds upwardly and beneath the body of the wrapped article, in other words turn under the end folds longitudinally of said article. In order to maintain the article and its wrapper in proper contact with said folder-plates 57, as the same passes over said folder-plates, there is provided a pair of presser-weights 69, which register above said folder-plates within said guide-members 62. Said presser weights are tied together by means of a strap-member 70 extending transversely yacross the same, and connected with said strap-member is a finger-piece 71, by means of which said presser-weights may be removed or inserted in position. The forward end of each presser-weight is rounded on its under side, as at 72, to permit said article and its wrapper to slip beneath the same, as it is moved over said folder-plates 57, the force of gravity causing said presserweights to bear down upon said article and its wrapper, and thereby maintaining the same in contact with said folder-plates so as to be properly acted upon by said end folding mechanism.
The carrying or propelling means for propelling said*article and its wrapper through said end folding mechanism comprises, a reciprocating propeller frame formed by the side-portions 7 3, which are slidably supported in guide-blocks 74 aiiixed to the inner sides of said side-frames 2. Connected with the forward; ends of said side-portions 73, is a transverse bar 75, and arranged upon said bar 75, so as to -project upwardly therefrom are propeller members 76, preferably three in number, each of which is provided with projections or lugs 77 adapted to engage one longitudinal edge of said article and its wrapper in order to push or propel the same through said end folding mechanism, and into the opening or slot 37 of said `label wrapping roll or cylinder 36. The
outer of the three propeller members 76 are provided with rearwardly extending pushtongues 78. Suitably connected between said side-port-ions 73, and in a proper position, is a cross-bar 7 9, the same being provided upon its rear side with a connectingpiece 80 carrying a fulcrum pin 81. The said frame, formed as above described, is reciprocated by the following means Journaled in the lower rear portions of said side frames 2 is a rock-shaft 82 extending transversely of said side-frames, and secured upon said rock-shaft 82, in any suitable manner, is an oscillating lever 83 to the upper end of which is pivotally .connected j lals tha-said fulcrum pin 81 carried by said connectin piece 80. Also secured upon said rock-s aft 82 is a crank-arm 85', provided at its :free endv with-a slot or opening 86 in which is adjustably secured a journal-pin 87. Journaled upon said journal pin 87 is oneend of a connecting rod 88, the opposite end of which is connected with an eccentric 89, the latter being mounted upon and oper'- ated bysaid driving shaft 4. When vsaid driving shaft 4 is rotated said eccentric, 89 operates to oscillate said crank-arm 85, to rock said rock-shaft 82 which in turnfoscillates said oscillating lever 83, which imparts through the medium of said connecting link 84, a properlytimed forward and backward movement orreciprocation to said propeller frame, Upon the rearward or propelling movement of said propeller frame, sald ropeller members 76 must be maintained) in contact with said article and its wrapper continuously so as to properly deliver the same to said label wrapping roll or cylinder 36, -but after this is accomylished, said vpro- .peller members 76 must e returned and brought into propelling engagement with anotherarticle and its wrapper which has been delivered lfrom said wrapping roll or cylinder upon said folder-plates 57 and beneath said foldin bar 55; and, to so do must be passed beneat the awaiting article and its wrapper, and then raised into roper propelling contact therewith, (all 1n the manner more particularl indicated in Fi 6 of the drawings). o accomplish this end, the following mechanism is 'provided Suitably locked, so as to extend transversely between said side-frames 2, is a guide-block 90 in the opening 91 of which is slidably arranged the stem 92 of a vertically reciprocating guide-table 93, which slidably supports and guides said transversebar and the propeller members 76 connected therewith in their backward and forward movements. Connected with t-he lower end of said stem 92 is a cam-portion 94 which rides upon a rotating cam-member 95, which is secured upon and driven by said drivingshaft 4. Said cam-member 95 is provided with a depressed or cutaway portion 96. Said cam-portion 94 of the stem 92 may be provided with forked tail-pieces 97 which straddle said driving shaft 4 upon either side of said rotating cam-member-95, and tend to maintain the respective cam-faces in proper riding contact with each other.
The operation of said cam-member 95 when rotated causes the elevation of said guidetable 93 during the backward or propelling movement of said propeller frame, whereby said propeller members 76 are maintained in proper contact with said article and its wrapper, after said article and its wrapper have been delivered to said label wrapplng roll or cylinder 36 however,
and said propeller member is again traveling forward, the low surface 96 ofsaid cammember 95 passes beneath said cam-portion 94 of said stem 92, permitting the stem 92, and guide-table 93 to descend slightly, which 1n frame and its propeller members 76, so that thesame may pass beneath the next awaiting article and its wradpper which it is to propel l rearwardly tower vsaid label wra 0r lc linder 36. Just prior to the xginning off-t e rearward or propelling movement of said propeller frame,I the high surface of said cam-member 95 a ain contacts with the cam-portion 94 of saidg stem 92, whereby the latter, and the guide-table 93 are again raised, to carry -upwardly 'said propeller frame. and its propeller members, thereby bringing the latter into operative contact with the article to be propelled. The cammember 95 is so arranged upon the driving shaft 4 that its functions are performed at proper times with relation to the reci rocating means of said propeller frame, w ich is also driven lfrom said driving shaft 4. As the said label wrapping roll or cylinder 36 makes its half revolution, 50 from the label feeding mechanisms 52, which is thus presented across the mouth of the opening or slot 37, when said label -wrappin roll or cylind-r comes to a stop, wit-h sai slot or openin in registration or alinement with said folerfplates 57, from which the propeller mechanlsm delivers the wrapped article against the label, thereby forcing both the wrapped article and its label into said opening or slot 37, with the latter folded partially about the former. This accomplished the said propeller mechanism withdraws to its normal initial position ready to operate upon a subse uent article and its wrapper. The said abel wrapping roll or cylinder 36 is now caused to make another half-revolution which y,earries over the wrapped article and its label, in the manner illustrated in Fig. 6. The propeller mechanism again operates to insert another wrapped article and a label into the opening or slot 37, in the manner above described, and simultaneously the said pushtongues 78 connected with said "ille-aller mechanism push forward into sai slotrv or opening 37, contacting with said projections or lugs of said push device or element 38, which moves the latter to eject the previously inserted wrapped article and its label from said opening or slot 37, and beneath a folding bar 98 which extends transversely above the mouth 99 of a receiving chute 100, thereby making the last longitudinal fold of the label about the wrapped article. Located above said label wrapping roll or cylinder 36 is a gum-reservoir 101, feed rolls 102, and gumming fingers 103 which are operated through a train of gears ping roll turn ,carries downwardly the propeller it picks up a label 104 meshing with a gear-portion 105 connected with the end of said wrapping roll or cylinder 36. As the projecting last fold of the label is carried around by said label wrapping roll or cylinder, it is carried in contactwith said gumming fingers 103, which apply thereto suiicient gum to glue down said last fold to the first fold of said label, when said folds are completed.
The wrapped and labeled articles are delivered into said receiving chute 100 at the lower end, hence it is necessary to lift up such articles as have already been delivered thereto in order to permit the insertion of subsequent articles. To accomplish this there is provided in the carrier-plate 106, upon which said receiving chute 100 is carried, an opening 107 registering with the bottom of said chute. In this opening is arranged a lift-plate 108, which is maintained normally at the level of said carrierplate 106 by means of supporting lugs or projections 109 located within said opening 107. Said lift-plate is na-rrower than the width of said articles within the chute so that when the lift-plate is raised it permits the article delivered from the label wrapping roll or cylinder to be inserted beneath the projecting longitudinal edges of thepile of articles already within the chute, whereupon said lift-plate is dropped kback to its normal level and said article is completely inserted beneath the pile within said receiving chute. The means for accomplishing the timely raising of said lift-plate 108 comj lever-arms 110 pivotally A poorly or improperly wrapped article prises a pair of connected upon a transversely extending rod 111, said lever-arms extend forwardly and.
beneath said lift-plate 108. Connected so as to extend transversely between said leverarms 110 in proper location is a cross-bar 112,
the same being chamfered on its forward. Connected with the cross-bar 79 of said propeller mechanism is a pivotallyf mounted nosing or cam-portion 113, having an adjustable stop-portion 114 which limits lower edge.
its movement in one direction and permits the proper engagement thereof with said cross-bar 112, when said propeller mecha-,-
nism moves rearwardly, thereby raising said lever-arms 110 and causing the same to engage said lift-plate 108 to raise that also. Socketed in said cross-bar 79 is a springmember 115 which in engaging said nosing 113 tends to maintain the same in its operative position, yet permitting the same to yield upon the opposite or forward movement of said propeller mechanism, so as not to operate to throw said lever-arms 110 in operative contact with said lift-plate 108. Said lift-plate is returned to its normal initial position by means of said springmembers 116, which are secured to the under side of saidl carrier-plate 106, and are connected by means of the screws 117, which ranged in said guide-way,
pass through their slotted ends 118, with said lift-plate 108.
Said receiving chute 100 is movably arranged, so that 1t may be removed from its operative relation to said label wrapping roll or cylinder 36, should it be desirable to gain access to the latter. To this end, said carrier-plate 106 is slidably supported upon the upper edges of said side-frames 2, being lproperly guided and slidably maintained thereon by means of the angle-pieces 119, which are provided in their upper portions with slots 120. Passing through said slots 120, so as to be slidable vertically in the openings 121 in the ends of said carrierplate 106, are lock-pins 122, provided at their upper ends with linger-pieces 123, and at their, lower or inner ends with bolt-pieces 124, which are normally received in boltsockets 125 arranged in of said side frames 2, whereby said carrierplate 106 and said receiving chute 100 are locked in their normal operative positions. When vsaid bolt-pieces 124 are raised out of said bolt-sockets 125, said carrier-plate 106 may be moved rearwardly and away from said label wrapping roll or cylinder.
