WRAPPING MACHINE.

Application filed July 1. 1922. Serial No. 572,148.

To all whom it may concern:

Be it known that I, MILFORD B. FERGU- SON, a citizen of the United States, residing at Brooklyn, in the county of Kings, in the State of New York, have invented certain new and useful Improvements in Wrapping Machines, of which the following is a specification. 1

The invention relates to an improvement in wrapping machines and more particularly to an improvement in wrapping machines of the type especially adapted for wrapping substantially cylindrical articles such as piecesof candy and the like.

The object of the invention is to improve upon the construction and arrangement of the parts of wrapping machines .of this type in order that the operation of enclosing the article in its wrapper may be more expeditiously and accurately performed than that has been possible in wrapping machines heretofore constructed for that purpose. With this object in view the invention consists in the improved wrapping machine hereinafter described and particularly pointed out in the claims. t

The preferred form of the invention is illustrated in the accompanying drawin s, in which Fig. 1 is a front elevation of t e improved wrapping machine. certain arts being removed; Fig. 2 is a top plan 0 the parts shown in Fig. 1; Fig. 3 is a side elevation of the right hand end of the machine; Fig. 4 is a transverse section, on an enlarged scale. taken on substantially the line H of Fig. 2; Fig. 5 is a side elevation, partly in section, of the Wrapper and article advancing mechanism, showing a modified means for actuating the wrapper carrier; Fig. 6 is a plan of the parts shown in Fig. 5; Figs. 7, 8, 9 and 10 are detail views showing the progressive stages during the operation of enclosing the article in its wrapper; Fig. 11 is a detail view, partly in section, of the mechanism for twisting the ends of the Wrapper; Fig. 12 is a perspective view of the cradle for looping the tape; and Fig. 13 is a perspective view of the wrapped article.

The improved wrapping machine, as illustrated in the drawings, comprises wrapper folding devices consisting of a flexible tape or apron mounted on an arc-shaped support, means for advancing or feeding a Wrapper and cylindrical article to the tape, means for looping the tape about the wrapper and article and causing the loop to travel to thereby enclose the article these various mechanisms are more or less broadly novel.

The flexible tape 15 by which the cylindrical article is enclosed in a wrapper is supported in position on the upper arcshaped surface 16 of a tape support 17 mounted on the stud 18 secured in the upper part of the upright 19 rising from the table 20 supported by the legs 21. At the lower end of the front side of the arcshaped tape support 17 is an article receivmg pocket 24 formed between the lower end 25 of the support 17 and the pivotally mounted jaw 26. A spring 27. tends to close the pocket, and the normal opening in the pocket is determined by a pin 28 against which the spring 27 presses the upright arm 29 of the iaw 26. When the wrapper and article advancing means have been actuated to force the tape and the wrapper and article into the pocket 24, as shown in Fig. 7, a rotating cradle, generally indicated at 30 (Fig. 12), is actuated to loop the tape about the article and wrapper and move the loop along the arcuate surface 16 of the support 17- to thereby roll the article, by which movement the article is enclosed in its wrapper.

The cradle 30 rotates in a clockwise direction, viewing Fig. 3. and so the loop formed in the tape for enclosing the article in its wrapper travels in the same direction. Various arrangements of belts or tapes may be used for enclosing the article in its wrapper. In the machine shown, the tape is in strap form and consequently after the wrapping of each article the tape must be pulled back to its original position and then slackened again previous to the insertion of the next wrapper and article in the pocket 24. For this purpose, the lower end 32 of the front side of the tape is fastened to the forward end of the arm 33 of a bellcrank lever 34 pivoted at 35 on the rear of naled at each end in the legs 21. One end of the cam shaft 44, projects beyond the right hand leg 21 (viewing Fig. 1) and carries a gear 46 which is driven by a pinion 47 mounted on the right hand end of the main shaft 48 whichextends across the machine and is journaled in the upper part of the legs 21. The left hand end of the shaft 48 carries a pulley 49 which may be driven from any suitable source of power. A hand wheel 50 fixed on the end of the shaft 44 afiords a convenient means by which the operating parts in the machine may be turned over.

The movements imparted to the arm 33 by the cam 43 are so timed that the forward 1 end of the arm 33 is moved downwardly to pull the tape 15 back to its original position after a wrapped article has been discharged and then is raised to slacken the tape to permit it to enter the pocket 24 with the next wrapper and article. The upward movement of the forward end of the arm 33 is proportioned to the slack required when the loop is formed. about the article, as shown in Fig. 8. The rear'side of the tape 15 is kept taut at all times and for this purpose the lower end 52 thereof is secured to a ivoted arm 53 which is pulled downward y (to keep the tape taut) by the spring 55.

The rotating cradle 30 which serves to loop the tape about the wrapper and article and carry the loo along the arcuate surface of the support 1 to roll the article into its wrapper comprises two arms '55 and 56, held in fixed relation with each other by two large cross rods 57 and two smaller rods 58, all of which are fixed in the ends of the arms 55 and 56. The arm 55 is loosely mounted on the stud 18 and the arm 56 is disc to which the gear 64 is secured, both of which are mounted on a stud 66 secured in the lower part of the upright 61. In the outer face 0 the disc 65 are formed four on the end of an arm 70 fixed on one end of insects of a shaft 71 journaled in the upper part of the right hand leg 21 (viewing Fig. 1), the outer end of which shaft carries a gear 72 which is driven by the pinion 47. As the arm 70 rotates, the 'roll 68 successively enters the slots 67 and thereby imparts an intermittent movement to the {cradle 30.

The loops are formed in the tape by the cross rods 58, and to eliminate friction the tape engaging parts of the rods 58 are provided with loosely mounted collars or rolls 75, held in place between two collars 76 fixed to the rods 58, as shown in Fig. 11. The cross rods 57 also contact with the tape, but they are not provided with anti-friction bearings inasmuch as they do not perform any active function in the wrapping operation. The rods 57 are provided with collars 59 spaced apart to serve as ides for the tape. The surfaces of the antl-fricti-on rolls 75 on the rods 58 are spaced from the axis of the stud 18 such a distance that they are separated from the arcuate surface. 16 by the support 17 about twice the thiclmess of the tape 15, andthe cross rods 57 are so located as to clear the arcuate surface during the rotation of the cradle.

as f

When the wrapper has been rolled about I the article, the ends of the wrapper are then folded to secure it in place, as shown in Fig. 13. It is preferred to make the end folds by twisting the parts of the wrapper extending beyond the ends of the article, although other well known kinds of end folds may be made. The twisting means may be movable or stationary, depending on the nature of the article to be wrapped. In the machine shown, the means for twisting the ends of the wrapper comprise a pair of fingers 80 located on opposite sides of the tape 15 and which are adapted to press the projecting ends of the wrapper down against the collars 76, which are flattened on one side for this purpose. The fingers 80 hold the ends of the wrapper against the collars 76 while the wrapped article is still rolled along on the arcuate surface of the support 17 by the rotation of the cradle 30. By thus holding the ends of the wrapper fast and rotating the article, the twists 81 article.

Each wrapper engaging finger 80 is pivotally mounted'at 82 on the end of an arm 83 secured to the flattened side 'ot'asegmental gear 84 mounted on a pin 85 "pivoted in the inner end of a support 86 projecting inwardly from the ends of the arms 55 and 56. [During the first part of the wrapper folding operation and until the wrapper is rolled about the article,.. the fingers 80 are held in the position shown in dot and dash lines in Fig. 11. The fingers are moved into engagement with the wrapper by the out"- ward movement of the rack 88 which en- 115 in the wrapper are formed at the ends of the gages the teeth of the segment 84. The rack 88 is formed on the inner end of a plunger 89 having a reduced middle portion 90 which is surrounded by an expansion spring 91 acting 'to press the plunger 89 outwardly and thereby bring the finger 80 downward toward the collar 76. Inward movements to lift the finger 80 out of engagement with the end extensions of the wrapper are imparted to the plunger .89 from a cam 93 fixed to the head of each upright 19 and 61. The outer end of each plunger 89 presses against a set screw 94 adjustably secured in one end of a lever 95 pivoted at 96 on a bracket 97 projecting outwardly from each of the arms 55 and 56. The other end of the lever 95 carries a cam roll 98 which is "'ressed into engagement with the cam 93. ifVhile the roll 98 travels on the raised portion 99 of the cam the spring 91 is compressed and the finger 80 is held away from the collar 76, but when the roll 98 is brought opposite the'depression 100 in the cam 93 by the rotation of the cradle 30, the spring 91 acts to force the roll 98 into the depression and thereby swing the finger 80 into engagement with the end extension of the wrapper. It will be observed that while the twist is being formed the end extension of the wrapper shortens and the end thereof travels toward the article. A contraction spring 102 returns the finger to its normal position so that it may be brought into engagement in the first instance with the extreme end of the wrapper.

The articles to be wrapped may be fed to the machine in any preferred way, depending upon the character of the articles. It

I is assumed for purposes of illustration and description that the articles wrapped in the present machine are substantially cylindrical pieces of candy known as tafiy, which are supplied to the machine by a hopper 105. The hopper is supported on the upward extension 106 of a bracket 107 resting on the table 20. The articles 108 are fed to the wrapper folding devices one at a time by a plunger 109 mounted to reciprocate under the lower open end of the hopper. The plunger 109 is supported at its forward end on a block 110 which projects laterally from a slide 111 mounted to slide in a guideway 112 formed in the upper part of the bracket 107.

Reciprocating movements are imparted to the plunger 109 from a cam 114 mounted on the cam shaft 44. The connections between the plunger 109 and the cam 114 comprise a bell-crank lever 115 pivoted at 116 on a bracket secured to the front of the machine. One arm 117 of the bell-crank carries a cam roll 118 which travels in a groove formed in the side of the cam disc 114. The other arm 119 of the bell-crank is connected by a link 120 with the block 110. Intermittent recipro- "eating movements are imparted to the plunger 109 from the cam 114 in timed relation with the intermittent rotation of the cradle 30 to insert an article and a wrapper in the pocket 24 immediately after the ejection of a wrapped article from the machine.

The wrapper in which the cylindrical article is to be enclosed is fed to the machine from a roll of wrapper material (not shown), either paper or tin' foil, by means of feed rolls 122 and 123. The forward end of the wrapper material is received in avertically arranged slot 124 formed in the upright extension 125 of the head 126 carried on the rear end of the slide 127 mounted to reciprocate in a guideway 128 formed in the lower side of the block 110. When the end of the wrapping material has been advanced into the slot 124 the requisite length is cut off by the shears 130. The feed rolls and the shears are indicated diagrammatically, because the construction and mode of operation of these parts are old and well-known. The feed rolls are mounted on a bracket 131 supported from the table 20. The roll 122 is actuated to feed the wrapper material into the slot 124 and for this purpose the shaft 132 on which the roll is mounted carries a gear 134 which meshes with and is driven by a gear 135 (Figs. 1 and 2.) The gear 135 meshes witha gear 136 ,mounted on a stud 137. Secured to the gear 136 is a pinion 139 which meshes with and is driven by a gear 140 mounted on a stud 141. Secured to the gear 140 is a ratchet wheel 142 arranged to be actuated by a pawl 144 carried by a lever 145 pivoted on the stud 141. The free end of the lever 145 is articulated by a universal connection 147 with the upper end of a lever 148 pivoted on the stud39. The lever 148 carries a roll 149 which travels in a path formed in the side of a cam 150 mounted on the camshaft 44.

The wrapper 153 (Figs. 4-and 5) in which the article is to be enclosed, is carried toward the tape 15 in front of the article. When the wrapper reaches the tape it is arrested, while the article continues its movemerit carrying the wrapper and the tape into the pocket 24. The mechanism by which this mode of operation of the wrapper carrier or slide 127 is secured comprises a link 154 con nected at one end with the upright arm- 119 of the bell-crank lever 115. The other end of the link 154 is bifurcated and loosely braces a block 155 pivotally mounted at 156 on a lug 157 projecting downwardly from the slide 127. A spring 158 received in a bore in the link 154 presses against the block 155 and imparts the rearward movement of the arm 119 to the slide 127. When the rear side of the upright is in close proximity to the forward side of the tape, the lug 157 encounters a set screw 160 adjustably secured in the upper end of an upright 161 rising from the table 20. Thus the arm I end of the link.

A modified form of the mechanism for actuating the slide 127 is shown in Fig. 5. This modified construction comprises a cam groove 164 formed in a projection 165 extending downwardly from the bottom of the slide 127. The' cam groove 164 receives a roll 166 mounted on the free end of an arm 167 secured to the lever arm 119. The form of the cam groove 164 is such that the slide 127 moves with the plunger 109 until the roll passes the point 169 in the cam groove. During further actuation of the lever 119 the slide 127 remains stationary, because the lower end 170 of the cam groove is cut on an are having the axis of the stud 116 as its center. It will be observed that'the are on which the lower end of the cam groove 170 is cut is determined by the position of the rojection 165 as indicated by the dot and ash lines in Fig. 5.

The mode of operation of the parts of the improved wrapping machine thus far described has been briefly indicated in connection with'the description of the various parts of the machine. It will conduce to clearness to recapitulate the progressive steps of the operation of enclosing the cylindrical article in its wrapper. The wrapper material is fed forward into the slot 124 in the rear end of the wrapper carrier or slide 127 and the requisite length is cut off by the. shears ,130. The plunger 109 and the slide 127 then move toward the tape, the slide 127 carrying the wrapper 153 and the plunger 109 pushing the article 108 which rests on top of the head 126. When the rear side of the upright 125 is in close proximity to the tape, the movement of the slide 127 is arrested while the plunger 109 is actuated to force the article, wrapper and tape into the pocket 24. Substantially simultaneously with the insertion of the article and wrapper into the pocket 24 the arm 33 is raised to give the requisite slack to the tape. The position of the essential parts of the wrapper folding devices at this stage of the operation is shown in Fig. 7. Immediately following the insertion of the wra per and article in the pocket 24, the cradle 30 is again actuated to bringone of the anti-friction rolls into engagement with the tape and carry-it upwardly past the pocket, thereby pulling the article out of the pocket, as shown in Fig. 8. The relation of the parts is clearly shown in the figure, and it will be observed that the end 172 of the wrapper is in position to be foldweenie the travel of the loop 174 in the-tape along the arcuate surface of the support 17 causes the article to roll. Fig. 9 shows the positions of the parts after the loop 174 has traveled a short distance on the arcuate surface of the support 17. It will be observed that the wrapper 153 has been almost entirely rolled about the article 108. Upon the completion of the act of rolling the wrapper about the article, the fingers are brought down onto the ends of the parts of the wrapper projecting beyond the article, as shown in Fig. 11. The continued travel of the loop 174 and the article 108 causes the twists 81 to be formed between the ends of the wrapper and the ends of the article. When the ends of the wrapper have been twisted sufliciently to hold the wrapper on the article, the article is in condition to be discharged from the machine. The relative positions of the parts just before the wrapped article is discharged from the machine are indicated in Fig. 10.

The act of discharging the wrapped article 17 5 from the wrapper folding devices is illustrated in Fig. 4. While the arm 33 has been rising to permit the loop 174 to travel along the arcuate surface of the tape support, the spring-pressed arm 53 has kept the rear side of the tape taut, so that when the article passes beyond the rear end 176 of the tape support, the wrapped article 175 is forcibly ejected from the loop in which it has been held. The wrapped article is received in a pan 178 mounted on an arm 179 pivoted at 180 on a bracket 181 secured to the table 20. When the pan 178 has received the wrapped article, it is actuated to discharge the article from the machine. The pan is actuated from the cam 183 fixed on the cam shaft 44. A cam roll 184 carried on the outer end of an arm 185 of a lever 186 pivoted on the stud 39 is held in engagement with the periphery of the cam 183 by a spring 187 secured at one end of the arm 188 of the lever 186 and at the other end to a fixed arm 189. The upper end of the arm 188 is connected by a link 191 with the lower end of an arm 192 secured to the hub of the pan supporting arm 179. The cam 183 is so formed that the pan 178 is moved under the rear end of the tape support 17 to receive the wrapped article 175 and then is swung outwardly to discharge the article from the machine and to be out of the path of travel of the cross rods 58 and 57 as the cradle 30 continues its rotation. It will be observed, however, that the cradle 30 temporarily comes to rest at the moment the wrapped'article falls from the support 17 into the pan. This intermittent movement of the cradle 30 and the other parts cooperating therewith to wrap the article, is optional inasmuch as the cradle 30 may rotate continuously. In this connection it will be observed that the wrapper folding devices carried by the cradle 30 are in duplicate and located at opposite sides of the cradle and that they occupy a relatively small arc. Consequently sufficient time is allowed for the pan 178 to move into position to receive the wrapped article and to move out of the path of travel of the cradle, for the tape shifting arm 33 to function, and for the wrapper and article advancing means to insert the Wrapper and article in the pocket 24 after the completion of the Wrapping of one article and before the tape is looped about the next article, without interferring with a continuous rotation of the cradle 30. In the preferred form of the invention, however, the cradle 30 is actuated intermittently.

It will have been observed from the above description of the improved wrapping machine taken in connection with th accompanying drawings, that the present invention comprises means for supporting a flexible tape in an arcuate position and rotating means for looping the tape about the article and causing the loop to travel to roll the article in its wrapper. Cooperating with the means for rolling the wrapper about the cylindrical part of the article are gripping means for holding the ends of the wrapper so as to cause a twist tobe made in the wrapper as the article continues to rotate. By holding the ends of the wrapper.

fast while rotating the middle part of the wrapper, the twists in the wra per are so formed that they thereafter ten to occupy their original condition, as shown in Fig. 13. The wrapper is synchronously move'l with the article until the point is reached where the two are to be carried against the tape, at which point the wrapper is held-in the path of movement of the article and is carried by the article with the tape into the pocket by which the first art of the loop in the tape is formed. It Wlll be understood therefore that many changes may be made in the form and arrangen'ient of the parts in the machine illustrated and described and still be within the principle of the wrapping machine defined by the following claims.
