12 Claims. (Cl. 53-194) space, was expensive, complicated to operate and in many instances did not produce the desired results.

It is therefore an object of this invention to provide a compact, unitary, fully automatic machine for Wrapping small articles in foil or similar material.

It is also an object of the invention to provide a wrapping machine wherein individual wrapping containers are continuously formed from a source of wrapping material and may be thereafter lled, sealed and removed from the machine without requiring the constant attention of an operator.

It is another object of the invention to provide a wrapping machine wherein a strip of wrapping material, emanating from a source of supply, is folded into a tube, cut to a desired length, closed at one end to form an open ended container and thereafter filled with a desired article of manufacture, closed at its open end and ejected from the machine, all steps following consecutively without requiring the attention of an operator.

It is a further an object of the invention to provide a wrapping machine wherein a strip of wrapping material, emanating from a source of supply, is continuously fed to a mandrel, which cooperates with an open ended die to form open ended containers which thereafter may be automatically lled with an article of manufacture, sealed at their open end and ejected from the machine, all steps following consecutively without requiring the attention of an operator.

With these and other objects in mind, reference is had to the attached sheets of drawings, illustrating one form of the invention, wherein like characters represent like parts, and in which:

Refering now to the drawings, and Figs. l to 3 in particular, a base 20 mounts a motor 2l and a speed reducer 22 which are connected, in driving relation, through a chain belt 23, to an operating assembly, generally indicated by the numeral 24. A drive shaft 25, connected through a pulley 26 to the belt 23, is journaled in posts 27, 28, and 29, mounted on base 20, and carries a plurality of operating cams, to be more fully described below, for rotation therewith. Also mounted on shaft 25, for rotation therewith, is a rubber covered roller 30, which drives a second rubber covered roller 3d, journaled in posts 28 and 29, the pair of rollers cooperating to continuously feed a ribbon 32, of foil or similar Wrapping material, from a source of supply (not shown).

Spaced from shaft 25, and in line with the path of feed of wrapping material ribbon 32, are supports 33, which are mounted on the base and adapted to movably support a spring-back weight 34. The spring-back weight, which includes a pair of rollers 35 secured to a shaft 36, is adapted to ride above and in engagement with ribbon 32, for a purpose to be discussed below.

Continuing along the path of feed of ribbon 32, a folder or trumpet die 37, mounted on base 241, turns the longitudinal edges of the ribbon upwardly to form a tube and guides the same around a mandrel 38. The mandrel, which extends parallel with frame Ztl in the direction of feed of the ribbon 32, is connected by a support 39 to a frame 40, which, in turn, is slidably mounted by the base 20 (Fig. 3). A vacuum is adapted to be drawn on the mandrel, through support 39 and the vacuum channel 41, formed in the frame 40, when the frame is in alignment with vacuum coupling 42, from a source of vacuum (not shown). A sleeve 43, which is connected to said source of vacuum, through coupling 44 and passage 44a, is adapted to movably ensleeve mandrel 38, for forming the end of ribbon 32 into a tube 32a. Adjacent sleeve 43, and adapted to receive mandrel 38 with tube 32a, of wrapping material, ensleeved thereon, is an open ended forming die 4S, which cooperates with the mandrel to close one end of the tube to form an open ended container B2b. The die 45, which is formed with a passage 46 extending into the mandrel receiving chamber 47, for connecting the chamber to a source of air under pressure (not shown), is mounted for relative movement with respect to base 20. A chamber 46a is formed in the die to connect the same to a source of vacuum. The die may, as shown in dotted lines in Fig. 2, be moved from its starting position, adjacent sleeve 43, to a station 48 for receiving an article of manufacture, such as a suppository, in container 32b, and thereafter to another station 49, at which point the open end of the container is closed and the Wrapped article ejected from the die.

`In the operation of the Wrapping machine, the ribbon 32, which is fed from a roll or similar source of supply, extends between the rubber covered rollers 30, 31, which continuously feed a certain length of the ribbon on each revolution of the rollers, beneath spring-back weight 34, through folder or trumpet die 37 into sleeve 43. We have found it advantageous to continuously feed wrapping material from massive rolls, as accomplished by the rubber covered rollers, since intermittently pulling the ribbon from the roll would result in excessive breakage. The mandrel 38 moves to theposition in sleeve 43, shown in Fig. 4, through the foil 32, which is held stationary on the inner surfacel of the sleeve by a vacuum being drawn through coupling 44 and passage 44a. ,The coupling is connected, through a valve 50, operated by follower 51 and cam 52, to said source of vacuum. As `a result of the ribbon being held stationary in sleeve 43, the continuous feed of rollers 30, 31 causes a -loop of ribbon to appear, as indicated at 56, for a purpose to be discussed below. With mandrel 38 in the above described position, and on the continued rotation of cam 52, by shaft 25, the valve 50 is shifted to disconnect the sleeve 43 from the source of vacuum and connect the mandrel thereto, through Vcoupling 42, channel 41 and support 39. The shifting of the vacuum from the sleeve to the mandrel transfers the ribbon 32, of foil or similar material, from the inner surface of the sleeve to the outer surface of the mandrel. This transfer literally takes place with a snap and results in the ribbon smoothly adhering -to the mandrel.

The mandrel 38 is moved to the right, as seen in Fig. 2, by cam 53, through follower 54 and linkage 55, such movement carrying the ribbon 32 through folder 37. The mandrel is adapted to move faster than the rollers 30, 31 can feed the ribbon to it, thereby eliminating the slack loop 56, when the mandrel reaches the position shown in Fig. 5. On eliminating the slack loop, the spring-back weight 34 is raised, by the ribbon, as indicated in, dotted lines in Fig. 2, and the ribbon becomes taut as illustrated at 57.

It is here noted, that though the construction of the vacuum seizing portion of the sleeve and mandrel may be of many different types, in the illustrated form of the invention a series of adjacent parallel grooves 58 are prothe shearing collar and its leading edge is permitted to remain at the plane of shear it will be picked up by the retracting mandrel and m-auled with the result that further operation will be substantially impossible.

vided, which are connected to the source of Vacuum.`

The ribbon 32 rests on the lands 59, formed between the grooves. When a vacuum is drawn on the ribbon by the sleeve or the mandrel, the ribbon has a tendency to enter the grooves 58, thereby substantially locking it in position.

In order to eliminate wrinkling of the ribbon as it is adv resorted to for preventing wrinkling of the ribbon 32.

Continued movement of mandrel 38 to the right, after ribbon 32 has become taut, as above described, results in slippage of the ribbon over the surface of the mandrel due to the restraining action of the rubber covered rollers 30, 31. Simultaneously, the shearing edge 63 of the mandrel enters the shearing collar 64 of the sleeve (Fig. 5) and, there being no clearance between edge 63 and collar 64, the ribbon 32, is parted at the line of contact, -to form a substantially cylindrical tube 32a, adapted to move with the mandrel.

Shearing of the ribbon occurs once for each complete revolution of rollers 30, 31 and, since the ribbon is taut between the rollers and the plane of shear, an exact length of tubing is cut. back weight 34, which retains the ribbon 32 under tension, drops to the position indicated in solid lines in Fig. 2 and the ribbon springs back away from the collar 64 as indicated in Fig. 7. The spring-back action of the weight 34, on the ribbon 32 is necessary to facilitate the subsequent re-entry of the shearing edge 63 of the mandrel into `the sleeve 43. If the ribbon is notdrawn away from At the instant of parting, the spring- `70 or similar means.

During most of the travel of mandrel 38 to the right, the rounded forming end 65 thereof has been moving into the open ended forming die 45 as illustrated in Fig. 5. On the final movement of the mandrel to the right, the ribbon tube 32a, which overhangs lthe end of the mandrel by slightly more than one half of its diameter (Fig. 5), encounters the shaped end wall 66 of the forming die, Where with further movement of the mandrel, it is formed into a cylindrical container 32b having one end closed (Fig. 7).

During the movement of mandrel 38 to the right, as above described, vacuum control cam 52 has maintained vacuum control valve 50 in position to connect the mandrel and disconnect the sleeve from the source ofvacuum. It at this point should be noted, that the forming die 45 is connected to the source of vacuum through passage 46a, coupling 4Gb and the same conduits as sleeve 43 and therefore is simultaneously connected and disconnected with the sleeve. After container 32b has been formed in die 45, cam 52 shifts valve 50 to disconnect mandrel 38 from the source of Vacuum and connect lthe sleeve and forming die thereto. vAs a result of this shift, the container 3219 is transferred from the outer surface of the mandrel to the inner surface of the die, permitting the mandrel to be withdrawn to the left. Simultaneously, the strip of foil 32 is transferred from the outer surface of the rear end of the mandrel to the inner surface of the sleeve enabling the forming end of the mandrel to be returned to its starting position within the sleeve as illustrated in Fig. 4. The forming die, which now has container 32E adhered to its inner surface may conveniently include a structure of grooves 58 and lands 59 as was described with respect to the mandrel and the sleeve.

When mandrel 38 has been moved to the left and comes to rest at its starting position, the forming die 45, with shaped container 32b mounted therein, is moved to station 48 adjacent the ejection point of a molding machineor a feeding device as indicated in dotted lines in Fig. 2 and illustrated in detail in Fig. 8. Movement of the forming die is controlled by cam 67 through follower 68 and linkage 69. .It is contemplated that an article of manufacture such as a suppository, candy, lipstick or the like will be inserted in container 3211 by means of plunger After the article has been seated in the container, the forming die 45 is moved, as a result of 'the continued rotation of cam 67 to a position adjacent station 49 as indicated in dotted lines in Fig. 2 and illustrated in detail in Figs. 9 through 1l.

Station 49, which is adapted to spin or wipe closed the open end of container 32b comprises a stationary member 71 secured to frame 20 of the machine and adapted to rotatably mount a cylindrical body 72. A bushing 4assembly 73 is mounted on cylindrical body 72, the assembly including a bearing col-lar 74 and a collar 75 keyed to the cylindrical body for rotation therewith. A pulley 76 is keyed to cylindrical body 72 and connects the same in driving relation to motor 77 through belt 78. Mounted on body 72 between collar 75 and pulley 76 is a lhelical spring 79 adapted to retain the bushing assembly and pulley in spaced relationship with respect to one another. A twister or wiper element 80 is pivotally secured at opposite sides of body 72 and is adapted to extend longitudinally of the same to a point outwardly of the end of the body adjacent forming die 45 between the former and pulley 76. The twister element 80 includes two substantially L-shaped arms, the short leg of each L-shaped arm terminating -in a cam 81, and the arms being connected by a transverse container contact bar 82. A substantially U-shaped yoke 83 is pivotally connectedto stationary member 71 as at 84 and slidably engages outwardly extending studs 85,

formed on bearing collar 74, in slots 86. In the operation of twister or closing station 49, the cylindrical body 72 is rotated by motor 77 and the yoke 83 which is connected through linkage 87 and follower 88 to cam 89 is pivoted in the direction of forming die 45, by the rotation of the cam, compressing spring 79 and forcing the thrust washer 90, on body 72, into engagement with rib 91 on stationary member 71. Continued pivoting of yoke 83 in the direction of the forming die further compresses the spring land shifts bushing 73 axially of the body to engage the camming portion 81 of twister element 80, -thereby camming twister bar 82 into engagement with the open end of container 32h, mounted in the forming die (see dotted and solid lines in Fig. '11). In this manner, the open end of container 32h is closed providing a completely packaged article 92 as illustrated in Fig. 12.

It has been found, in addition to the fact that a very fine seal can be obtained by rotating a rounded blade transversely of the open end of a container, that there is a marked difference in the quality of the seal if the blade is turned into the overlapped flap of the container rather than in the direction of the overlap. If the blade or spinner is lturned in the direction of the overlap the sealed end of the container is formed with a protruding ear of material but if it is rotated in the opposite direction a flat relatively smooth seal is provided as shown in detail at 92a in Figs. l2 and 13.

After container 32b has had its open end closed to form a finished packaged article 92, a cam 93, acting through a follower 94 opens a valve 95 to connect the passage 46, in the forming die 45, through coupling 96, to a source of air under pressure (not shown). The resulting air jet through coupling 96 and passage 46 ejects the packaged article 92 through the hollow chamber 97 which extends longitudinally of twister body 72 and thence through a tube 98 to any appropriate receptacle, not shown.

The invention, as above described, is adapted to be utilized in combination with a molding machine for articles such as suppositories, candy, lipstick and the like. Due to the multiplicity of functions performed by the machine, however, it is suitable for a wide variety of applications, the various elements of its structure being readily adapted to structural redesign facilitating its association with other machine sand manufacturing systems. It is also contemplated that portions of the structure, and the principles on which they rely, may be utilized in an apparatus for the manufacture of article containers or wrappers.

Thus, among others, the several objects of the invention as aforenoted are achieved. Obviously, numerous changes in the structure may be resorted to without departing from the spirit of the invention as dened by the claims.
