Definitions
- the present invention relates to a process for the manufacture of packages, to a machine for its manufacture and to a container obtained with said process, said packages being formed from a plurality of overlapping sheets and joined together, and being especially suitable for contain food
- packages are formed by a plurality of layers of sheet material, depending on the number and material of the layers of the type of food they must contain.
- the layers are made of cardboard or expanded polystyrene, also comprising a layer of a sheet material suitable for being in contact with food.
- the packages may comprise an additional layer of absorbent material placed below the layer of suitable material to be in contact with food.
- cardboard containers have the disadvantage that they are not very resistant and do not retain their memory, that is, they deform and do not recover their shape original. This is because during the drawing stage to form the container according to a predetermined design folds are formed in the embedded areas, these folds being able to deform if a pressure is applied thereon.
- the manufacturing processes of this type of packaging usually include the steps of:
- the sheets are first glued, joining them together, they are punched out and then all the sheets are embedded together. This drawing of all the sheets together is what causes the appearance of folds.
- Another drawback is the necessary power of the punching of the drawing station, since they have to embed a series of layers together.
- the tolerance between the punches and the dies of the drawing station has to be quite large, since a plurality of layers with a certain thickness have to be drawn together.
- the present invention relates to a process for the manufacture of packages, which is characterized by the fact that it comprises the steps of: - gluing said plurality of sheets from coils of sheet material;
- this can be done both cold and hot, achieving a very high manufacturing speed compared to known procedures.
- the power required to stuff the sheets is reduced, since only one sheet is drawn into each of the stations, and not all of the sheets together as before.
- the process of the invention also comprises the additional step of trimming the edges of the container after drawing and joining all the sheets together.
- the package is made from at least three coils of sheet material, the first sheet material being suitable for contact with food and that, when making the drawing and joining of all the sheets, it will be arranged in the internal part of the container.
- At least one of said coils is made of cardboard, the sheet or sheets remaining from the coil or cardboard coils arranged between the first sheet of material suitable for being in contact with food and the sheet disposed more external when drawing and joining all the sheets.
- grooves or holes can be made in the die cutting stage on the first sheet of suitable material to be in contact with food.
- the treatment of an area of the cardboard sheet or sheets corresponding to the grooves or holes of the first sheet for the absorption of the juices produced by the product to be packaged is also carried out. predetermined areas
- the treatment of the cardboard sheet or sheets is carried out by spraying a suitable material to avoid porosity in some areas of said sheet or sheets.
- the sheets are pre-cut and the marks are made for subsequent drawing in each of the sheets.
- At least one of said sheets has different dimensions than the rest of the sheets.
- a reinforcing or absorbent sheet of smaller dimensions may be included among the others sheets.
- the present invention also relates to a machine for the manufacture of packages, characterized by the fact that it comprises: - a series of gluing stations, the number of gluing stations coinciding with the number of coils of sheet material or its lower quantity in one unit with respect to the number of coils; a series of stamping stations that puncture a plurality of sheets from two coils of sheet material, the number of stamping stations coinciding with the number of coils of sheet material; a series of drawing stations, formed by a plurality of punches and dies, the number of drawing stations coinciding with the number of coils of sheet material, with these joining stations being made joining all the sheets together; and - means for transferring the already embedded sheet or sheets from one drawing station to the others, so that a first sheet passes successively through all the drawing stations, with one sheet being added individually in each of said stations to said station. First sheet until the final conformation of the container.
- the machine of the invention also comprises a cutting station, where the edges of the already formed container are trimmed after joining all the sheets together.
- the machine can also comprise at least one additional station of treatment of an area of at least one of said sheets.
- the coils of sheet material are arranged next to each other, the coil corresponding to the innermost sheet of the package already formed at one end and the coil corresponding to the outermost sheet of the package already formed at the other end.
- the dies of the drawing stations are arranged next to each other and facing the exit of the sheet material from the coils.
- the present invention also relates to a package manufactured according to the above procedure and with the machine described.
- Figure 1 is a schematic plan view of the machine of the invention
- Figure 2 is a schematic elevational view of the machine of the invention.
- - four sizing stations 2 four stamping stations 3 that punch a plurality of sheets from coils of laminar material la, Ib, le, Id; - four drawing stations 4, formed by a plurality of punches 5 and dies, making these joining stations 4 the union of all the sheets with each other; - transfer means 6, such as, for example, a conveyor belt, of the sheet or sheets already inlaid from one stuffing station 4 to the others, so that a first sheet passes successively through all the stuffing stations 4, adding from individually a sheet in each of said stations to said first sheet until the final conformation of the container;
- - transfer means 6 such as, for example, a conveyor belt, of the sheet or sheets already inlaid from one stuffing station 4 to the others, so that a first sheet passes successively through all the stuffing stations 4, adding from individually a sheet in each of said stations to said first sheet until the final conformation of the container;
- this machine is designed for the manufacture of four-layer containers of sheet material, being able to manufacture packages of more or less layers by adding or removing the corresponding stations.
- the innermost sheet of the already formed container is of a material suitable for being in contact with food and can be printed if desired.
- This sheet can be made of a hot melt and waterproof material, depending on the requirements.
- the outermost sheet of the already formed container can be of any suitable material, such as paper or others, and can be printed.
- the intermediate sheet or sheets, two in the case of the package manufactured with the machine shown in the drawings, are preferably made of cardboard.
- the coils of laminar material are placed first, Ib, le, Id in position, so that they supply said material to the stations described.
- the driving means of said coils for the supply of the material may be any suitable means.
- the machine of the invention will be synchronized so that, when the operation of the same starts, first the material of the first coil is supplied, the left coil in the machine represented.
- the sheet material will first pass through the gluing station 2, where a section thereof will be glued.
- the glue used will be hot melt, allowing it to cool before drawing.
- the sheet material is stamped and marked according to a predetermined design, making the marks for subsequent drawing.
- the machine of the invention will be synchronized so that the manufacturing of packages is carried out continuously.
- an additional spraying operation can be performed on some area of the sheet material. This spraying is done to treat some areas, avoiding porosity in some areas of the sheet or sheets.
- the gluing of the first sheet is not essential, and the gluing station corresponding to the first coil can be removed. It should be noted that some of the sheets that make up the package may have a different dimension to the dimensions of the rest of the layers. For example, a reinforcing sheet of smaller dimensions may be included among the other sheets. In addition, at least one of the coils can also be arranged in a different direction from the rest of the coils, thus allowing the fibers of the sheet material of this reel or coils to be crossed with the fibers of the rest of the laminar materials. In this way, it is achieved that the container has a greater stability of its shape, avoiding deformations.
- transfer means of the already formed sheets may refer to the transfer means of the already formed sheets.
- these transfer means are a conveyor belt that is provided with the matrices, the same being fixed on the belt. In this way it is achieved that the same matrix passes successively through all the filling stations. It should be noted that the punches could be fixed on the conveyor belt, these being the ones that would go through all the filling stations.
