WRAPPING MACHINE.

Application filed December 16, 1920. Serial No. 481,085.

To all whom it may concern.

Be it known that we, FRANK MQPETERS and WARREN H. HUNonRronn, both citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wrapping Machines, of which the following is a specification.

Our invention has reference more par-' ticularly to apparatus for enclosing an article or package in a wrapper, and also includes mechanism for connecting the wrapper together so as to fasten the wrapper in place on the article or package.

The principal objects of our invention are to provide a simple and compact mechanism for enclosing an article or a ackage in a wrapper; to cement the ends 0 the wrapper together so as to secure the wrapper on the package; to effect the connection of the ends of the wrapper at the same time that the ends are folded against the package; to insure the drawing and folding of the wrapper smoothly and uniformly around the package; to provide improved wrapper delivery and guiding-means, to provide guiding means which shall also contribute to the folding operation, and in general to provide an improved apparatus which is adapted to fold a wrapper around a package more expeditiously and in a more,satisfactory manner than heretofore, and to which devices may be readily "applied for cementing the ends of the wrapper together.

On the drawings- Fig. 1 is a side view, with parts in section, of a machine embodying our improvements;

Figs. 10 and 11 are edge and side views respectively of the rear part of the said wrapper-holder which also; serves to fold the lower end of the wrapper up against the face of the package.

Referring to the drawings- The reference numerals 1 and indicate portions of the right and left slde frame members respectively of the machine, which are suitably constructed to support the various mechanisms of which the machine is composed. A transverse shaft 4 isljournaled in these frame members 1 and 2 and has a carrier 3 thereon with pockets or recesses 5 extending transversely in the periphery thereof and adapted to receive the packages successively therein at the first stage of the wrapping operation. In the structure illustrated there are four pockets or recesses 5, although it is to be understood that 'the number thereof may be varied, and this carrier is operated from the main driving shaft 6 through the gears 7, 8 and 9, and a Geneva gear consisting of the disk 10, which is connected so as to rotate with the gear 9 and provided with a roller 11 operating in the radial slots 12 of the four-point star wheel 13, whereby intermittent operation of the carrier 3 is effected so as to turn the carrier 3 oneua turn at each revolution of the disk 10. The driving arrangement also provides a sufiicient period of rest between each'quarterturning movement to permlt the packages to be inserted in the pockets 5 and the folding of the ends of the wrapper to be effected.

In the present machine the packageis inserted horizontally from a conveyor belt.- into the pockets as they reach a position at one side of the machine, and the wra per in which the package is to be enclosed 1s interposed between the cket 5 and the position of the package on t e carrier or belt, so that the operation of inserting the package into rofa' the pocket serves to fold the wrapper partially around the package. The belt 14 which feeds. the packages passes around belt-wheels or pulleys 15 and 16 so that the upper length thereof is substantially in the same horizontal plane as the bottom wall of each pocket 5 when located in the receiving position, rollers 17 being arranged at intervals under the upper length "of the belt to prevent sagging. There are also rollers 18, over which the lower length of the belt is passed so as to be held above paste-applying mechanism, as will hereafter more fully appear. The belt 1 1 is operated in the direction indicated by the arrow in Fig. 2 by the drive belt 19, which receives power from any suitable source of power and is connected with a belt-wheel 20 which rotates with the belt-wheel 16, the driving connection being arranged to advance the packages fast enough so that a package is positioned ready to be inserted in each pocket 5 as these pockets are moved successively to the receiving position adjacent the upper length of the belt 14. The belt may be operated continuously at a comparatively low rate of speed or intermittently at a higher rate of speed, as desired, and to insure that the package is being held at the proper point for insertion in the pocket 5, a stop 21 is arranged in the path of movement of the packages on the belt so as to obstruct the packages and hold them against further movement with the belt when they are posi- J tioned directly in front of the pocket 5.

This stop is adjustable, being carried on the end of a shaft or stem 22 which is threaded through a hub 23 on the frame of the machine. A hand-wheel 24 is secured on the outer end of the stem 23 for adjusting same, and a lock-nut 25 on the threaded portion of the stem clamps against the outer face of the frame member to hold the stop against displacement when adjusted to the proper position.

A pair of uprights 26 is located adjacent the rear edge of the belt 14 and one at each side of the carrier 3, as shown in Fig. 2, at the upper ends of which is a chute 27 arranged to feed a sheet 28 of wrapping material to an upright position between the belt 14 and the carrier 3, the lower end of the chute being positioned just above the path of movement of the package from the belt 14 to the pocket 5 and adapted to retain the upper portion of the wrapper therein until it is folded around the package. The sheets 28 are supplied successively at proper times from the stack 29 in any suitable man ner through feed rolls 30 which direct the sheets into the upper end of the chute 27 and impart suflicient momentum thereto, so that said sheets drop down to the proper position in front of the pocket 5, into which the package is to be inserted.

A combined wrapper-holder and folding member is located below and in line with the lower or outlet end of the chute 27 so as to receive the lower end of the wrapper 28 therein from the chute 27, and co-operat'e with'the lower end of the chute to hold the wrapper in the upright position, the holder and folding member being normally positioned just below the upper length of the belt 14, so as to leave space between the holder and the lower end of the chute 27 through which the package may be inserted from the belt into the pocket 5 of the carrier. This holder comprises two parts, one of which serves as a front support'for the wrapper, while the other serves as a rear support therefor, the former having a. pair of side wings 31, connected together at their lower ends by a cross-bar 32 and provided at their outer edges with, shoes120 slidable between the guide-flanges 33 on the uprights 26, so that the wings 31 are held thereby'in line with the outer wall of the chute 27 and cause the wrapper 28 to drop down along the rear side of the side wings 31. The upper ends of the wings 31 are rounded outwardly, as indicated at 34, and the shoes beveled or tapered, as at 121, so as to direct the wrapper to the required position along the rear face of the wings 31. At. each end of the cross-bar 32 is a. bearing 35 for a shaft 36, and a plate 37 which forms the other part of the wrapper-holder is pivoted along its lower edge on this shaft 36. An arm 38 extends rearwardly and upwardly from the bar 32 at a point midway between the ends thereof and has a, forwardly extending stop 39, against which the rear face of the plate 37 is normally held by the spring 40, which has one end connected to the upper end of the arm 38 and the other end connected to the lug 41 on the rear face of the plate 37. The plate 37 which is of substantially the same width as the distance between the side wings 31, and extends up-' wardly to substantially the same elevation, is mounted on the shaft 36 so as to be held by the spring 40 against the stop 39 in a vertical plane spaced a short distance to the rear of the wings 39, so that the wrapper 28 is admitted between the, plate 37 and wings 31 when fed downwardly through the chute 27 and the bar 32 has a flat upper surface and extends across the space intervening between the side wings 31 and the plate 37 to serve as a stop against which the lower edge of the wrapper 28 engages when it drops down between the side wings 31 and the plate 37, and when so engaged, the wrapper projects above and below the line of passage of the package from the belt 14 to the pocket 5'.

Extending transversely across the machine at a distance in front of the combined paper-guide and folder 31-37 is a shaft 42 which has a sprocket 43 thereon I connected by the chain 44 with a sprocket 45 on a transverse shaft 46, which is mounted in an elevated position above the paper-guide 27 and has a sprocket 118 thereon, which is connected by the chain 47 with a sprocket-wheel 48 on the drive shaft 6, so that the shafts 42 and 46 are operated simultaneously with and at the same rate of speed as the shaft 6. Arms 49 are pivoted at their forward ends on a shaft 50 extending transversely of the machine and are joined together intermediate of their ends by a cross-brace 51 so as to swing in unison, and the rear ends of these arms are connected by the links 52 with the shaft 36 which forms the pivotal connection between the side wings 31 and the plate 37 of the combined wrapper-holder and folding device. A cam 53, which is fixed on the shaft 42, is located so as to engage a roller 54 on one of the arms 49 and normally holds said arms downwardly, and the combined paper-guide and folder 3137 in the lowermost position, against the tension of the spring 55 which has one end connected to the cross-brace 51 and the other end to the bracket 56, which extends forwardly from the cross-plate 57 of the inachine frame. This cam 53 has a recess 58 in its periphery which is arranged so as to be engaged by the roller 54 and permit the spring 55 to elevate the \arms 49 at the proper time to raise the combined paperguide and folder 3137 so that the'rounded edge or bead 59 on the upper edge of the plate 37 moves over the outer face of the package in the front pocket 5 of the carrier 3 and serves to fold the lower end of the wrapper 28 against the face of the package and cement same in place.

The wrappers are fed into the machine at the termination of the operation of folding and sealing the lower end of the receding wrapper, andwhile the combined guide and folder 3137 is in the elevated position, the depression 58 in the periphery of the cam 53 being of sufficient length as shown in Fig. 1 so that the combined guide and folder remains elevated for a period of time for this purpose. The upper end of the combined guide and folder when elevated is so close to the lower end of the chute 27 that practically a continuous guide for the wrapper is afforded and there is therefore no possibility of the leading end of the wrapper being misdirected as it emerges from the chute 27. After the wrapper drops down into the combined guide and folder 3137 the latter is returnedto the lowermost position by the cam 53, and as the'wrapper 1s Supported on the flat top of the bar 32 it drops down with the combined guide and folder to the position shown in Fig. 1.

An upstanding arm 60 is also pivoted at its lower end on the shaft 50 and connected at its upper end to the outer end of the flat shaft 61 which is mounted in a bearing 62 carried by the bracket 56 so as to slide transversely of the belt 14, and this shaft has a head 63 secured on the forward end and adapted to be projected by the shaft 61 across the upper surface of the upper length of the belt 14, for the purpose of inserting packages from the belt into the pocket 5 of the carrier-wheel 3. The upper end of the arm '60 is forked to straddle the shaft 61,- and each branch is correspondingly slotted at 64 and enga ed by the pin 65 on the outer end of the s aft 61'. A cam 66 on'the shaft 42 bears against a roller 67 on the arm 60 and normally holds said arm outwardly against the tension of the spring 68 which has one end connected with the arm 60 adjacent the upper end thereof and the other end connected with the bracket 56, said cam being provided with a recess 69 in the periphery thereof, which, at the proper time, permits the spring 68 to throw the arm 60 inwardly and thereby project the-head 63 inwardly for the purpose of forcing a package from the belt 14 into the adjacent pocket 5 of the carrier-wheel.

As hereinbefore indicated, the wrappers 28 from the stack 29' are fed successively into the chute 27 just before each operation ofthe plunger head 63, and these wrappers assume a position, as indicated at 28 in Fig. 1, wherein the intermediate portion thereof is directly opposite or in front of the pocket 5, into which the package is to be inserted, and has the lower end thereof projecting downwardly into the combined guide and folder 3137, and the upper end thereof remaining in the lower extremity (if the chute 27; When the head 63 is operated to insert a package from the belt 14 into the pocket 5, the package, therefore, engages the intermediate-portion of the wrapper 28 and forces same, together with the package, into the pocket 5, thereby folding the wrapper around three sides of the package and withdrawingthe. ends of the wrapper from the guide and folder 3137 and the lower end of the chute 27, substantially as indicated in Fig. 5, so that only the extremities thereof remain in the guide and folder and chute.

Each of the pockets 5 has a shoulder 70 at the base thereof which serves as a stop 1 'against which the package engages when fully inserted, and at one side of each pocket is a plate 71 which is resiliently mounted so as to bear against the package as it is inserted, so that the wrapper is drawn smoothly therearound. This plate; as well as the opposite wall of the pocket 5, is rounded at the outer edge, as indicated in Fig. 1, to facilitate entrance of the package into the pocket, and the plate 71 is arranged at a slight inclination, as shown in Fig. 1, for the same purpose. For mounting the plate 71 in the pocket 5, the latter has one or more spring seats 74 at one side thereof adjacent the outer edge, and one or more spring seats 80 near the base of the pockets in which springs 7 5 and 79 respectively are held, the latter being engaged between the base of the seat 80 and the plate 71 and held in proper engagement with the plate by a stud 78 on the late and inserted in the end of the spring 9, whereas the other spring 75 is compressed between the base of the seat 74 and a collar 76 on a stem 73, to the end of which the plate is pivoted by the pin 72. The stem 73 rojects through an aperture in the base 0 the spring seat 74 and has a nut 77 threaded on the outer end for adjusting the pin 73 to regulate the distance between the plate 71 and the opposite wall of the pocket 5 and vary the angular position of the plate, while at the same time lateral displacement of the plate 71 against the tension of the springs 75 and 79 is permitted when the package is inserted in the pocket 5. The pressure of the plate 71 against the bottom of the package when the latter is being placed in the pocket 5, serves to hold the top of the package against the upper wall of the pocket 5 at a corresponding pressure, so that the wrapper 28 is held firmly in place against the package and thereby caused to be drawn uniformly from the guide and folder 3137 and the lower end of the chute 27.

Mounted on the upperends of the uprights 26. and extending rearwardly therefrom are plates 81 which are formed on their inner faces with spaced flanges 82 formin a guideway therebetween in which the end s of a plate 83 are mounted, so that the latter slides vertically. This plate has pivot lugs 84 on the rear face thereof, between which the lower end of a bar 85 is pivoted, and the upper end of this bar is forked, as at 86, so as to straddle the shaft 46, and has a roller 87 on one side thereof which enga es a groove 88 in the cam disk 89 on the s aft 46, said cam groove being ofi'set at 90 so as to raise and lower the bar 85 and plate 83 at each revolution of the shaft 46. V

A plate 91 is located in front of thevplate 83 and has pivot lugs 92 adjacent the upper end which engage pivot pins 93 carried by bosses 94 on the front of the plate 83, and there is an' upward extension 95 at each end of the plate 91, each of which is engaged by the end of a spring 96 which has the other end engaged against an upward extension of the plate 83 so as to normally hold the plate 91 against a stop lug '97 which projects forwardly from the lower edge of the plate 83 and limits the swinging movement of the plate 91 on the pivot pins 93.

The shaft 46 is suitably connected with the shaft 42 and the cams 89 and 66 arranged so that the plate 9i is moved downwardly just after the head 63 forces the package into the pocket 5, andin its downward movement sweeps against the outer face of the package in the pocket 5, and thereby folds the upper end 98 of the wrapper down against the front face of the package, as shown in Fig. 6, the arrangement of the stop 97 being such that the springs 96 are permitted to cause the plate 91 to press the end of the wrapper against the package as it is folded down and thus draw said end smoothly over the front face of the package.

The cam 53 on the shaft 42 is arranged to effect the operation of the paper-guide and folder 3137 immediately after the end 98 of the wrap r has been folded down by the plate 91, t e recess 58 in this cam releasing the roller 54 at such time so that the arms 49 are elevated by the spring 55 and move the paper-guide and folder 37 upwardly, thereby folding the lower edge of the wrapper, which edge is indicated at 99, upwardly against the front face of the package so that the extreme lower edge of the wrapper overlaps the upper endportion 98 and is pressed thereagainst by the rounded edge or head 59 of the plate 37, the stop 39 being so arranged that the spring 40 is permitted to exert tension on the plate 37 at such time so that the rounded edge or head 59 bears at a tension against the front face of the package and thereby draws the wrapper end 99 smoothly over the face of the package and presses the overlapped ends firmly together.

It is desirable in applying the wrapper to the package to connect the overlapped ends of the wrapper together, and for this purpose pas'te-applying mechanism is provided, which applies paste along the lower edge of the wrapper before it is folded up around the package. This mechanism comprises a paste receptacle 100, which is located adjacent and at the front of the guide and folder 3137, and has a shaft 119 journaled in the end walls of the receptacle and carrying a roller 101, which extends down into the receptacle so as to dip into the paste therein. The shaft 119 has a sprocket 102 fixed on one end thereof and connected by the chain 103 to a sprocket 104 on the shaft 42 so as to be continuously rotated while the wrapping machine is in operation, and another roller 105 is mounted in an elevated position at one side of the receptacle 100 so as to engage the roller 101, and has a gear-wheel 106 on its shaft meshing with the gear-wheel 107 on the shaft of the roller 101 to insure positive rotation of the roller 105. An arm 108 said arm in the retracted position.

is slidably mounted in an aperture 109 in the frame plate 57 and has the outer end thereof bifurcated so as to straddle the shaft 42, and there is a roller 110 on this arm which engages a cam 111 on the shaft 42, said cam being provided with an elevation or tooth 112 on the periphery which, at the proper time, moves the arm 108 rearwardly against the resistance of the spring 113, said spring being connected with the arm 108 and the frame plate 57 so as to normall hold Tfie'rear end of this arm is formed with a yoke 114 in which a roller 115 is mounted, and in the normal position rests in contact with, the roller 105 so as to be rotated by the latter and have a coating of paste applied thereto. This roller is adjacent the lower end of the combined guide and folder 31-37 so as to be projected by the cam elevation 112 against the lower edge of the wrapper 28 just after the wrapper has been inserted in the position shown in Fig. 1, the roller being of a suitable length topass between ;the side wings 31- and press the lower edge of the wrapper against the back plate 37 so as to insure thorough application of the paste along the lower edge of the wrapper.

It will be observed that the wrapper 28 is of a width only a little less than the distance between the inner faces of the shoes 120, whereas the package, indicated at 116, I is of a length somewhat less than the width of the wrapper, and portions'of the wrapper, therefore, when folded around the package, project beyond the ends of the package. I These projecting portions are subsequently folded down against the ends of the package, the mechanism for effecting this latter folding not being shown in the present construction. The connection of the overlapping edges of the wrapper is not continued throughout the entire width'of the wrapper but merely along the portions, of the overlapping edges which are'directly over the lateral surface of the package. The roller therefor is of a length substan-. tially the same as the distance between the wings 3131 and corresponds with the width of the plate 37, the upper rounded edge of which serves to press the overlapping edges together so that the paste will cause them to stick together.

i As her'einbefore explained,the carrier 3 is advanced in a step by ste manner a quarter-turn at a time by the eneva gearing 1013, so that the pockets 5 are brought successively to the position at which the package is inserted therein from the belt 14, and the Geneva gearing affords an interval of rest between each successive operation of the carrier 3, during which the head 63 is first operated to inject the package and wrapper into the pocket 5 and then the plate 91 is depressed to fold the upper end of the wrapper down alon the front face of the package,and then t e plate 37 is elevated to fold the lower end of the wrapper up along the front face of the package and cement the edges together :after which the carrier 3 rotates in the direction indicated by the arrow in Fig. 1, so as to bring another pocket 5 into the filling position and carry the package to which the wrapper has 'ust been applied to other mechanism (not s own) for completing the folding of the wrapper, applying labels, etc. In order to insure thorough adhesion of the overlapped edges of the wrapper to one another, a brush 117 is mounted adjacent the periphery of the carrier 3, so that as the packa e is' carried away from the position at which it is inserted into the carrler, the outer face of the. ackage is swept over the bristles of the rush and the latter thereby rubs the one edge of the wrapper down against the other edge of the wrapper, so that they are caused to adhere firmly to one another.

It will also be observed by referring to Fig. 1 that the aste roller 115 comes in contact with the ower end of the wrap 'r 28 on a line a short distance above the ge so as to leave an uncoated mar The paste is thus applied, "as the rubbing of the upper edge of the plate 37 against the lower end of the wrapper as the latter is folded up over the upper end of the wrappergtends to flow the paste between the overla ped edges in the direction of movement 0 the plate 37, and if the aste were applied in the extreme lower go of the wra per it might result in the paste flowing out beyond the edge of the wrapper, onto the rounded edge 59, thereb causing a stic condition of said rounde edge which W0 (1 interfere with satisfactory operation of the said rounded edge on successive wrappers.

It is to beunderstood that the packages 116 are placed on the belt 14 so as to move endwise to the position from which they are inserted into the, pockets 5, and these packages may be fed onto the belt 14 by hand or automatically,as desired, mecha nism not being shown for'this purpose as it forms no part of the present invention. By using the plain belt 14 without wings or flights for propelling the package, weight of the package alone is do I ded upon to cause sameto move with e belt and'renders it unnecessary to have the operation of the belt timed exactly so as to bring the package exactly in position. It is only necessar that the belt 14 should operate at a suita e rate of speedtoinsure a ackage being carried up to position at or fore the time of operation of the head 63, as the Stop 21 wil hold the package in place and permits the belt 14 to continue operating without carrying the package bathe yond the proper position for insertion into the pockets 5.
