6 Claims, 3 Drawing Figures SHEET 2 LE PATENTEDJW 15 m4 WM lm/enlors bu f? APPARATUS FOR PRODUCING A PACKAGED ASSORTMENT OF DIFFERENT SWEETS The present invention relates to an apparatus for producing a packaged assortment, of the type known as a rod package, which contains a predetermined number of different kinds of sweets packed in the same package in the form of a rod.

Wrapping machines for sweets use in known manner a feeding ram, which transmits the sweets to be wrapped jointly with the surrounding wrapping material through a brush shaft into a gripper, which passes the already partly wrapped sweet along folding members, which complete the wrapping. In order to feed the sweets to the feeding ram feeders, by example, in form of an intermittently rotating plate are known, which are equipped at their periphery with receiving pockets, which are adjusted as to their configuration to the particular sweet shape. From a storage container the plate is fed by means of a vibrating channel or the like with sweets such, that the latter fill up the still empty receiving pockets in the plate and are brought individually to the feeding ram of the packing device.

Such packing devices are not suitable for obtaining a predetermined mixing ratio in the total packing, if a variety of types of sweets are applied. Often a demixture occurs on the feeding plate of the packing machine upon feeding of a plurality of types of sweets, so that in the total packing once small or less sweets of a particular type are contained and it could even occur, re-

spectively, that one type is not present at all is some packings. The aim, to produce a collective packing, in which the individual types of sweets are contained in a predetermined mixture ratio and a predetermined succession, respectively, could not be obtained with the known machines or apparatus.

It is one object of the present invention to provide an apparatus for producing a package assortment of sweets in which the drawbacks of the known machines are avoided.

It is another object of the present invention to provide an apparatus for producing a package assortment of different sweets, wherein the formation of a total packing of individual sweets to be wrapped is made possible, whereby the sweets are contained in the collecting package in a previously set mixing ratio and predetermined succession in the package.

It is still another object of the present invention to provide an apparatus for producing a package assortment of sweets wherein additional feeders fed from a particular sweets storage supply a sweet feeder feeding the ram of the packing device, which additional feeders are likewise equipped with receiving pockets and are intermittently moved, whereby the number and division of the receiving pockets in all feeders as well as their feeding speeds are adjusted to each other in such manner, that each preset feeder feeds only the receiving pocket or pockets of the feeder coordinated thereto, which supplies to their feeding ram 0f the pocket device with sweets.

Preferably the main feeder which supplies the feeding ram of the wrapping mechanism may be a pan feeder formed around its periphery with a plurality of consecutive pocketspand the supplementary feeders formed by similar pan feeders disposed about the circumference of the main feeder pan in such a way that the path of their pockets overlaps the path of the pockets of the main feeder pan and a sweet transfer point is formed between the main feeder pan and each supplementary-feeder pan where for the purpose of transfer the respective pockets move into exact register.

The main feeder and the associated supplementary feeders may rotate intermittently at the same angular speed and the angular pitch of the pockets around the peripheries of the feeder be a multiple of the angular pitch of the pockets in the main feeder. The actual pitch of the pockets of the feeder depends upon the sequence of the sweets in the packaged assortment that is to be produced. For example, if the sweet from a particular supplementary feeder is to occupy each third or sixth position in the completed package, then the pitch of the pockets in that feeder must be three times or six times of the pockets in the main feeder.

The size of the completed packaged assortment depends upon the number of sets of different kinds of sweets it contains, the number of pockets in the main feeder being a multiple of the number in one set of sweets. The spacing of the sweet transfer points of the supplementary feeder is equal to the number of sweets contained in a set of sweets multiplied by the spacing of the pockets in the main feeder.

The number of supplementary feeders is determined by the composition of a set of sweets. The several supplementary feeders may, for the purpose of varying the composition of the sets of sweets be exchangeable for other feeder pans having differently pitched pockets. On the other hand, the same feeder pans may be retained and some of their pockets not intended to participate in the feeding of sweets, either masked or filled. Each of the feeder pans may be provided with its own supply conveyor for sweets from an appropriate storage bin.

With these and other objects in view, which will become apparent in the following detailed description, the present invention which is shown by example only, will be clearly understood in connection with the accompany drawings, in which FIG. l is a schematic representation of a packaged assortment of different kinds of sweets produced by an apparatus according to the present invention;

FIG. 2 is a schematic plan view of a main feeder and four associated supplementary feeders of an apparatus according to the present invention; and

FIG. 3 is a vertical section through the main feeder and one of the supplementary feeders of the apparatus shown in FIG. 1.

Referring now to the drawings, FIG. 1 is an example of a package containing an assortment of sweets. This type of package is sometimes referred to as a rod package and contains in a common enveloping wrapper ll an assortment of individually wrapped sweets of kinds a,

b, c, d. Different numbers of confections a to d are present but they are arranged in recurring sets. Sweet a is followed by a sweet b, which is followed by a sweet 0,

which is followed by a sweet d. The next sweet b which is followed by another sweet c. The six sweets make up a complete set A. The single rod package shown contains two such sets A, each comprising the six sweets a, b, c, d, b, c, in that order, so that there are two sweets of type b and two sweets of kind 0, but only one sweet of kinds a and d in each set.

The number of sets A contained in a single rod 1 may be varied and the order of the individual sweets as well as the numbers of a particular kind of sweets in each set can also be changed by effecting appropriate changes in the apparatus that will be hereinafter described.

With reference to FIGS. 2 and 3, the apparatus comprises a main feeder pan 2, which is formed around its periphery with a plurality of pockets 3, each for the reception of a sweet that is to be wrapped. According to the shape of the sweet, these pockets may be round, polygonal or oval. In the illustrated example, the main feeder pan contains 42 such pockets around its periphery and can therefore accommodate seven sets A of sweets. The pitch of the pockets expressed in angular degrees is therefore three hundred and sixty divided by fortytwo. The pan 2 is rotatable intermittently anticlockwise in the arrowed direction in consecutive steps, the sweets which are received in the bare unwrapped state being conveyed in the pockets 3 over a lifting ram 4 which rises when the pan is stationary and from below lifts the sweet from the pocket 3, together with a wrapper 5 placed over the sweet, through a folding shaft or forming brush 6 to grippers 7 which accept the sweet and convey it past folding elements which complete the wrapping of the sweet. The sweets in predetermined numbers are then transferred to another part of the apparatus at which they are stacked in the form of a rod and together packed in a common wrapping envelope 1.

Supplementary feeders pans, 8, 9, 10 and 11 which are likewise formed with pockets 30, 3b, 3d, and 3a, respectively, are positioned around the periphery of the main feeder pan 2 as shown. Each ofthe supplementary feeder pans S to 11 is provided with an upright rim 12. The sweets a, b, or d are supplied from a storage bin 14 down a vibratory chute 13 is shaken by a vibrator 15.

The main feeder pan 2 is driven by an intermittent drive (not shown), preferably a Geneva stop. This rotates the pan 2 through an angle equal to l/42 of its full circumference driving each intermittent movement. Chains and spur wheels, (not shown) transmit the drive to the supplementary feeder pans 8 to 11, which rotate in intermittent steps at the same angular speed. The supplementary feeder pans pockets are so placed about the peripheries of the pans that their paths overlap the path of the pockets of the main feeder pan and that at a point of transfer B of a sweet a pocket 30 will be in exact register with a pocket 3 in the main feeder pan 2. The same applies to the other sweet transfer points B B and B The transfer points B to B in accordance'with the number of sweets in a set A are spaced apart a distance equal to six times the pitch of the pockets in the main feeder pan 2. Consequently the angular pitch of the pockets 3c and 3b in the two feeder pans 8 and 9 is three times the pitch of the pockets in the main feeder pan 2, because two sweets of each of the kinds b and c are contained in a set. On the other hand, in the case of the feeder pans l0 and 11, the angular pitch of the pockets is six times the angular pitch of the pockets in the main feeder pan 2, because each of the kinds a and d is needed only once in each'set of six.

All the pans 2 and 8 to 11 are exchangeable for other containing pockets of other shapes differently pitched. Supplementary feeder pans for other types of sweet may be associated with the main pan and, by suitably choosing the pan disposition, the angular pitch of the pockets and the number ofpans, a considerable variety of assortments can be assembled for packaging. Partic- 'ularxpockets in the feeder pansmay be masked or filled in order to accommmodate different variations in the arrangement of kinds of sweet in the completed package without exchanging the pan. Preferably all the pans are arranged to rotate synchronously at the same frequency of intermittent movement. At the sweet transfer points B the sweets fall from the supplementary feeder pan into a pocket of the main feeder pan underneath. This ensures that the sequence of the different sweets a to d will be exactly maintained as prescribed by the sequence in a set in the packaged assortment. The transfer of sweets takes place only when the pans are stationary. If necessary plungers or suckers could be provided at the transfer points B, in such manner that a positive transfer takes place. Moreover, instead of making use of supplementary and main feeder pans, chains fitted with pocket receptacles could also be used. The sweets can be sorted in any sequence irrespectively of the number of varieties present and the percentage of each variety in the package assortment can be repeated any number of times.

Although the illustrated example uses main and supplementary pans, the possibility of using chains or other conveyors should be specially noted. Furthermore, it is possible to dispose the supplementary feeder pans below the edge of the main pan and to convey the sweets from the pockets in the supplementary feeder pans from below by a lifting ram to the main feeder pan. It is also unnecessary to provide the main pan with fortytwo pockets. Other numbers of pockets variously pitched may be used for preparing packaged assortments, in which the sweets are combined in different ways.
