Machine for Making Packs of an Infusion Product

Abstract

A machine for making packs (2) of infusion products, created by a first sheet (21) of packaging material, forming a recess, in which a batched quantity of product (20) is placed, and a second sheet (22) of packaging material, applied on the first sheet (21) of packaging material and joined thereto peripherally. The machine includes a work assembly (30) for feeding the first sheets (21) to a carrousel (10), operated to rotate on a horizontal axis, in suitable step relation with the feeding of the sheets. The carrousel (10) has, made on its periphery, an ordered series of cavities (11), which receive the first sheets (21) for forming thereon, a respective recess, whose shape is suitable for containing the batched quantity of product (20). A filling group (40) introduces the batched quantity of product (20) into the recess formed on the first sheets (21), connected to the cavities (11) of the carrousel (10). A group (50) for feeding single second sheets (22) joins mutually the first and second sheets (21, 22) in an area all around the recess filled the batched quantities of product (20). A discharge work assembly (610) removes the packed products (2) from the carrousel (10).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a machine for making packs of infusion products, in particular coffee and the like.BACKGROUND OF THE INVENTION[0002]There are packs of infusion products used to obtain, by suitable machines, beverages like coffee or similar.[0003]These packs are usually called “pods”.[0004]In particular, the pods include a first sheet of filter paper, which forms a recess, containing a batched quantity of product, and a second sheet of filter paper, joined peripherally to the first sheet, so as to close the pack.[0005]The sheets of filter paper are usually made of heat-weldable material.[0006]Different types of machines have been worked out for producing the pod packs.[0007]These machines usually feed a first band of filter paper to a forming station, in which an ordered series of recesses are made on the band, arranged along one row or more rows situated one beside another.[0008]The so obtained recessed band is fed, in a substantially lin...

Benefits of technology

[0036]The object of the present invention is to resolve the above problems, by proposing a machine for making packs of infusion products, which allows efficient processing, optimizing the production rate and reducing the waste of packaging material.

[0038]Within the above objects, it is a further object of the present invention that of proposing a machine for making packs of infusion products, whose concept is simple, working reliable, use versatile, and dimensions reduced.

Problems solved by technology

The continuous machines operating on parallel lines can be used for more complicated packaging operations, which requires considerable time intervals.

However, the machines operating on parallel lines can be cumbersome, and thus require high costs due to the need of production spaces, especially when the processing operations to be performed are numerous and complicated.

These machines are complex and cumbersome and they have only one work assembly.

Thus, the known machines have considerable limitations related to the productivity and functionality, and they usually have a complicated structure, difficult to manage in the available spaces.

In the specific case of the machines for packaging infusion products, considerable disadvantages derive particularly from the fact that they package a plurality of products arranged adjacent to one another on a band being processed.

Actually, these machines usually produce a significant amount of scraps of filter paper, deriving from the cutting single packs, forming the pods, from the processed band, which results in the increase of production costs.

Another disadvantage of the prior art machines derives from the limits imposed by the type of filter paper, which can be used, in particular regarding the paper thickness.

A further disadvantage of the prior art machines is the limited number of the packs obtainable on the filter paper band in rows arranged one beside another.

Obviously, this limits the machine production capability.

Moreover, possible damage to one row of recesses, e.g. tearing, are easily transmitted to the row beside.
