<<,ο, οί provij ** ' ¹ '. v / v / g-tu.

Fig. 1 shows a packaging machine 10 according to the invention. Generally speaking, the machine receives an incoming supply of objects, such as beverage cans, and divides them into upper and lower feed paths. A baffle is added to the item array on the lower feed path, and then the baffle is manipulated so that the deformable zones of the baffle fit correctly on top of the articles. The topsheet of the articles is then superimposed on the partition in a coincident position with the bottom article such that the bottom of the top article fits into a moldable zone of the partition that engages the top of the bottom article. The stacked, separate bilayer of articles is then wrapped in a carton of the wrapping type in this example.

The fact that the upper and lower articles fit one another duty, as described in more detail below with reference to Fig. 2, that the stacked articles will no longer be more significant in the packaged articles must be up to 5 means storing or transporting the carton. Therefore, the carton laid firmly ensures that the tops in the wrapped carton wrapped around

Naturally, the partition 13 also and the bottoms of adjacent objects are

A-f · do not rub themselves, which would otherwise cause unsightly traces at the ends or at least one of the objects. For example, where articles A are made of aluminum, such permanent articles could at one end result in damage to the ends, rubbing against the adjacent end, superimposed on unsightly alumina deposits.

In addition, the movement of the articles can guide the ends of the articles, including tearing off the tear-off closures of the cans.

With a more specific reference to the components of the machine 10 than shown in FIG. 1, it can be seen that the two lower rows of articles 33 are fed into the machine on the conveyor 36. The flow of objects A in the rows 33 is controlled by a pair of so-called star wheels 40. The feed mechanism 16 pulls the baffle 13 from the container 12 which in this example includes an extension 14 to accommodate a large number of baffles 13. The feed mechanism 16 may have vacuum suction cups the front partition 13 from the extension and feeds it to a position adjacent to the tops of objects A, the lower row 33

As can be seen in FIG. 2, the baffle 13 has a side recess 60 that allows the baffle to be carried by the carrier chains 42 that are adjacent the tops of objects A on each side of the rows 33 Thus, with synchronized movement of the carrier chains 42 with controlled By flowing through the rows 33 and the feeder 16, the array of moldable objects may be zones and the partition 13 carried together by the partition walls.

13, which are aligned with the tops of articles A in this field.

The array of objects through the feed path k and the baffle are then fed along the lower baffle extrusion wheel 13. causing the locking tabs 64. indicated on the insert 10 so that they fit between the fields. In this example, they are displaced from the plane of the partition, the tops of adjacent objects in the lower being can objects A having a top flange E of less diameter than the main body diameter, substantially cylindrical. The locking tabs 64 may therefore be positioned in the gaps between the flanges of adjacent articles and thereby hold the partition 13 in place during movement of the lower array of articles.

The device which pushes the tabs 13 is shown in greater detail in Fig. 6, which shows that the device comprises a cylindrical wheel 74 rotating about its central axis which is driven by means not shown here and the radial extensions 70 are rotated with the wheel. 72 of the thumb 70 abuts the top surface of the locking tab 64 of the partition 13 as the fingers rotate to the lowest position. Advantageously, the ends of the panel 72 may be rounded to allow easy entry and exit of the inches from the apertures that delimit the tongue 64 in the partition 13.

The array of objects as shown in FIG. 3 is then carried to the forming wheel 20. 7. The forming wheel has a cylindrical surface 34 and rotates it about a cylinder axis not shown here. On the cylindrical surface of the wheel 34 are two rows of hollow cylindrical cups 80, each having a rim 32 simulating the base of the article. Again, the movement of the shaping wheel 20 is synchronized with the movement of the lower array of objects and partition so that the individual cups 30 form the moldable zone 62 at the baffles 13 to engage the tops of object A. As can be seen in FIG. an upper edge which is recessed in the longitudinal direction with respect to the upper flange R. Such a formable zone 62 forms a cup structure between the flange R and the end of the article. This arrangement is shown in FIG. 4. Thus, the baffle 13 can be held in position on the lower array of objects due to the action of one or both of the tongues 64 and the moldable zone 62. In addition, the drive chain 42 can still engage recesses 60 and thus ensure the exact position of the individual baffles 13 relative to the array of objects.

The upper laminate is now prepared so that, as shown in Fig. 4, the two upper layers 44 of the array of objects are at the top of the array,

In this example (see Fig. 1) of the objects fed by conveyors 22, the can rows can be guided by fixed rails not shown in the attached drawings. The flow of a series of objects 44 can be controlled by a star wheel 4®.

The movement of the two object fields, the upper one, is controlled by the device 43, which is more clearly in this example, the controller 49, which the upper and lower pair of objects, the star wheels 90 and 92. The star wheels consist of a set of toothed plates 94. The plates 94 have recesses 93. separated and lower, is then shown in Fig. 9.

The laminating effect consists of a pair of teeth 96 that engage a portion of the perimeter of the article. The lower and upper plate sets are adapted to engage lower and upper objects. The upper and lower sets of plates are separated by a joint 99 for the separating plate 91.

As can be seen in Fig. 9, the recessed recesses in the upper and lower sets of plates 94 cause the upper and lower objects to be discharged, so that as the star wheel 90 or 92 rotates, it causes a slippage which causes the upper object to engage the cup defined by the shape. zone 52 on top of the upper object. By repeating this procedure, a stacked field is formed as shown in FIG. 5. Naturally, the number of objects! in a stacked group, it can be any of a stacked pair, three or four stacked objects, etc. Fields can, of course, have any number of rows,

The stacked field may be fed as a unit, for example using a conventional conveyor below the lower array of articles, to a carton packing station.

In this example, the stacked array of articles is filled into a wrapping carton to form a carton 100 as shown in FIG. 10. Looking at FIG. 1, the machine 10 includes a carton 54 of a carton layer 26. The individual carton 100 may be pulled out of the face of the layer 26 by a feeder 23 similar to the feeder 16 described previously. Thus, the carton 100 may be moved from the magazine 24 to a feed chain 30 having, for example, carriers that engage the cooperating portions of the carton so that it can be moved to the chain boom section 50 of the boom chain 34 at the beginning of the top wall of the carton 110 114 and 124 of the carton 100 are the folding wheels 32. Side walls

34. Presses on the front of the upper body. The sides are then folded down by means of cartons and then guided by a cardboard side drive chain to the shoe expander 54. With the known insertion device 104, the carton is provided prior to pressing the side walls 114 and 124 of the carton onto the flanks of the stacked objects.

the objects that act, the feet of the objects by which

The outrigger chain 34 continues to press the top of the carton onto the preform box, while the known closing mechanism 56 causes the bead walls 116 and 122 and the bottom panels 113 and 120 to fold around the underside of the stacked object array. Alternatively, the bottom parts can be glued together.

Naturally, the individual stations or machine parts are independently operable and can be used in other types of carton packaging machinery, such as for cartons.
