Benefits of technology

[0011]The characteristics of the sealing member make it possible to package products of different sizes without having to change the sealing member every time that the size of the product changes, which makes the machine more versatile. The duration of the process is also reduced, as it is not necessary to perform an upper vacuum operation in order to vacuum-bond the product, so that the speed of the machine is increased. Furthermore, the amount of film to be used may be reduced by supplying in an equidistant manner the products to be packaged, by adjusting the distance between the products to as little as possible, due to the fact that regardless of the size of the products, the opening of the sealing member allows their size to be adapted, so that when the sealing member is applied on a product said sealing member does not collide with a previous product that is larger in size.

Problems solved by technology

As a result, the product is protected from external agents and generally the food products retain better the possible liquids of the product, thereby delaying the development of microbes, which means they have a longer useful life and create the possibility of displaying the package in a vertical manner, for example.
The closed construction of member 59 presents several problems.
First, it limits the maximum length of the product to be packaged.
Second, if a shorter product is to be packaged a significant amount of film is wasted, increasing the cost of packaging.

first embodiment

[0030]In the machine 100, the sealing member 1 corresponds with a sealing mould 1 and comprises a substantially U-lying shape, as shown in FIG. 2. When the sealing member 1 moves towards the sealing tool 9, the product 4 is disposed in a sealed space defined by the inner space 10 and the previously packaged product 4, thereby enabling the sealing of the films 2 and 3 around the product 4 by means of at least one lower vacuum and heat.

[0031]In a first configuration of the first embodiment the transverse wall 13 of the sealing member 1 is fixed in relation to the longitudinal walls 11 and 12.

[0032]In a second configuration of the first embodiment, the transverse wall 13 of the sealing member 1 is mobile in relation to the longitudinal walls 11 and 12. The second configuration is adapted for the case in which the products are supplied in an intermittent manner with a constant advance, and instead of moving the sealing member 1 in the advance direction X to be adapted to the different l...

second embodiment

[0033]In the machine 100 the sealing member 1 comprises, in addition to the walls 11, 12 and 13, at least one intermediate longitudinal wall 19 that is disposed between the longitudinal walls 11 and 12, which comprises a length substantially equal to the length of the longitudinal walls 11 and 12, and which is substantially parallel to the longitudinal walls 11 and 12, as shown in the example of FIG. 3. With the intermediate longitudinal wall 19 the sealing member 1 defines at least two inner spaces 10 disposed in parallel, a product 4 being disposed in each inner space 10 in order to be vacuum-packaged between both films 2 and 3. As a result, two or more products 4 may be packaged simultaneously in a single machine 100. The inner spaces 10 are separated from each other by intermediate longitudinal walls 19, the sealing member 1 comprising a substantially inverted E shape when it defines two inner spaces 10 and so on.

[0034]In a first configuration of the second embodiment, the inter...

third embodiment

[0036]In the machine 100 the sealing member 1 comprises, in addition to the walls 11, 12 and 13, at least one additional transverse wall 18 that is disposed transversally between the longitudinal walls 11 and 12, which comprises a length substantially equal to the length of the transverse wall 13, and which is substantially parallel to the transverse wall 13, as shown in the example of FIG. 4. With the additional transverse wall 18 the sealing member 1 defines at least two inner spaces 10 disposed in series, a product 4 being disposed in each inner space 10 to be vacuum-packaged between both films 2 and 3. As a result, two or more products 4 may be packaged simultaneously in a single machine 100. The inner spaces 10 are separated from each other by additional transverse walls 18.

[0037]In a first configuration of the third embodiment, the additional transverse wall 18 is mobile in relation to the longitudinal walls 11 and 12 in the advance direction X, as is the case in the second co...

Abstract

A packaging machine having a sealing member that acts on a product wrapped by a lower film and an upper film, and which seals or closes the films to each other around the product in order to vacuum-package said product between both films, and control means for causing the sealing member to move in order to package the product. The sealing member defines at least one inner space where the product to be vacuum-packaged is disposed wrapped at least partially by the two films. According to one implementation the sealing member includes at least one longitudinal first wall, a longitudinal second wall and a transverse wall between which the inner space is defined, and an unobstructed opening facing the transverse wall.

Description

TECHNICAL FIELD[0001]The invention relates to a machine for packaging products, of the type in which the product is vacuum-wrapped between two thermoplastic films that adapt to its shape and are sealed around it, and which is known as a skin packaging machine.BACKGROUND[0002]The technique in which a product (or products) is vacuum-wrapped between two films of thermoplastic material that adapt to its shape is known as skin packaging, and is a technique that is already known. As a result, the product is protected from external agents and generally the food products retain better the possible liquids of the product, thereby delaying the development of microbes, which means they have a longer useful life and create the possibility of displaying the package in a vertical manner, for example.[0003]In a skin package, the product is generally disposed on a first film or lower film, and is wrapped by a second film or upper film. In a sealing station both films are then joined or bonded aroun...
