Technical Field 0001) This invention relates to a packaging method using a degassing device and a packaging apparatus including a degassing device. This packaging method involves degassing the package or semi-hermetic package in a degassing device having a single vacuum chamber.

Prerequisites for creating an invention

I0002)| The packaging machine can be used for packaging food products. This product can be a bulk product or a product pre-loaded on a tray.

The plastic film tube can be continuously fed through the bag/bag filling and sealing machine. The film and the product are combined, for example, the product is placed on the film or the film is wrapped around the product. In some examples, the bulk product is fed via a feed conveyor. The tube is formed around the product by welding the opposite longitudinal edges of the film. Alternatively, the product is placed in a tube and the front edge of the package is welded. The tube is then welded to the rear edge (at the inlet end) of the package and detached from the tube of the continuously moving package. 0003) In some embodiments of the present invention, this tube can be presented as a tube itself or can be formed from two films or sheets welded in the longitudinal direction at two longitudinal edges, or from one film that is folded and welded along its longitudinal edges. In other embodiments of the present invention, products are loaded into preformed bags, which are then fed to a degassing device and a welding device. In addition, some variants of the implementation of this invention can facilitate the removal of gas from two or more packages at the same time within the framework of the same stage of the technological process. The latter can be implemented, for example, by processing two or more bags on the same degassing device or by feeding, in parallel, two or more tubes of film to a packaging machine, where these tubes are processed in parallel.

I0004| Sealing knives may be used to seal the package, whereby the lower knife and the upper knife are moved relative to each other to contact each other, compressing the packaging material between them and providing one or

From several seals. Typically, these welding knives also form a contiguous seal that includes the opposite edge of the next package, thereby providing one semi-hermetic (which has an open edge, for example) and one hermetic package during one step of the packaging process. (0005) Seals are generally cross-extending sections of packaging material that have been treated to provide a seal between the interior volume of the package and the environment. In the context of this document, whenever reference is made to the removal of a gas, it should be understood that the term "gas" may include a single specific gas or a mixture of gases, and may consist, for example, of air (ie, consist of a mixture of gases corresponding to the ambient air). In some embodiments of the present invention, packages may be filled with a shielding gas (which is sometimes also referred to as an "inert" gas). It should be noted that any known shielding gas or mixture of gases, such as CO, can be used here. 0006) The gas may be introduced into the package in the gap between the product and the film at the loading station with or without a first seal that closes the package at its first end (ie, rear edge). Any gas remaining inside the package after the gas or air has been removed from the package and after the package has been brewed provides a very low residual O2 level inside the package (e.g., a residual O2 level of 195 or less) . This is particularly useful in relation to the protection of perishable products (for example, cheese with a low level of gas formation during ripening).

I0007| Usually, the packaging machine is used for many different products in terms of type, size, weight, product composition, etc. There is a line of machines with a vacuum chamber for an application called "soft vacuum", in which the product (for example, soft or medium-hard cheese with holes) is vacuumed in machines based on a two-chamber apparatus. These two chambers are equipped with different values of air pressure and are separated from each other by a partition wall that has a gasket. The first chamber is a vacuum chamber equipped with vacuum gauge pressure. The second chamber is a vacuum chamber provided with a vacuum pressure that is higher than the vacuum pressure provided in the first chamber and contains the product placed in the bag. 0008) As a rule, such a layout can cause a number of limitations. For example, the complexity of 60 and the cost of the equipment leaves room for improvement through the many components required. In addition, the size of the products that can be processed depends on the size of the second chamber that holds the product during the packaging process. In some applications, it is difficult to provide chambers of sufficient size due to structural limitations of some components (eg actuators). Also, maintaining process reliability and component durability can be difficult as component sizes (eg, chambers, actuators, gaskets) increase, as size typically affects wear properties. In addition, the processing time may increase due to the vacuuming of large chambers, which takes a relatively longer time.

ИО009| Patent 05 2012/0174531 describes a packaging machine and a method of forming vacuum packaging. The first vacuum chamber is used to accommodate the portion of the package intended to accommodate the product, while the second vacuum chamber is used to accommodate the portion for opening the package. Pressure sensors measure the pressure in both chambers, and the air supply valve serves to supply air to the first chamber. This invention is characterized by the fact that the air supply valve is a control valve and is made adjustable depending on the difference between the pressure values that prevail in the first and second chambers, and which are measured by means of two pressure sensors.

This invention also relates to the fact that a gap is provided in the partition between the two chambers and that a regulator is provided to change and adjust the cross-sectional area of said gap. 00101 The patent EP 1564147 describes the apparatus and method for vacuum packaging the product in a bag. This apparatus includes a cover that is hinged to a base, the cover and base are provided with upper and lower intermediate walls that together form a first vacuum chamber, a second vacuum chamber adjacent to the first chamber, and an opening connecting the first and second chambers for passing through it the neck of the bag. This apparatus further includes means for emptying the first and second chambers independently of each other and means for closing the receiving container. This apparatus additionally includes a device for admitting air into the first vacuum chamber, and also provides an aperture with a device for reducing the passage of air from one chamber to another. The emptying process includes one or more cycles of alternating removal

From the air from the inner volume of the first and second vacuum chambers, while in some phases the pressure is at least partially restored in the first vacuum chamber.

ИЙО011| One of the purposes of the present invention is to provide a packaging method that facilitates efficient packaging of products of larger sizes, regardless of the size of the vacuum chamber or processing chamber. Another object of the present invention is to provide a packaging method that facilitates the removal of gas and/or air from the package - similar to vacuuming achieved by known apparatus and methods - using only one chamber. In particular, the purpose of this invention is to create a packaging machine capable of performing the packaging method according to the present invention.

Detailed description

I0OO56) In Fig. 1 and 2 show the first embodiment of the packaging apparatus according to the present invention. The packaging machine 1 includes a welding device 3, a gas removal device 35 and a moving device 30. The packaging machine 1 additionally includes a loading station (not shown). The moving device 30 is designed to move the product 20 placed inside the film 21 from the loading station in the direction of the welding device C and through this device, and in the direction of the gas removal device 35 and through this device.

I0057| Typically, products 20 are loaded onto a continuously fed film, such as fed from a roll of film (not shown), then the film is welded longitudinally to form a sequence of products 20 placed in a tubular film 21.

Alternatively, an injection device 34 may be provided to fill the inner volume of the tubular film 21 with a shielding gas or gas mixture. This gas or gases may, in fact, include or consist of CO. 0058) Products 20 to be packed allow different states (eg 20a, 205, 20c, 204) of packaging. States 20a, 200, 20c and 204 mean product 20. which is at different stages of packaging. For example, state 20a means product 20 located inside a tubular film 21, state 2065 means product 20 contained in a semi-hermetic package (ie, a package having a sealed edge and an open edge), and states 20c and 204 mean product 20 that contained in a sealed package (ie, in a package with two sealed edges, and the gas in the package may or may not have been removed).

І0059| In state 20a, the film 21 is placed around the product 20, or the product 20 is placed in the tubular film 21. Alternatively, in state 20, the product 20 is placed on the film 21, which is then folded and sealed at its longitudinal edges to form the tubular film 21. This step can be performed at the loading station and/or on a (separate) longitudinal welding device. 0060) The welding device C includes an upper welding and cutting element 31 and a lower welding and cutting element 32, made with the possibility of welding and cutting the film 21. The sealing and cutting elements 31 and 32 are made in such a way that

To form a first seal on the film 21, thereby forming a semi-hermetic package 23 containing the product 20 in state 200, and separating this semi-hermetic package 23 from the continuously fed film 21, which is brewed at the leading edge of the film. The product 20 in state 206 is located inside the film 21, and the semi-hermetic package 23 includes a sealed edge and an opposite open edge.

II0061| The degassing device 35 is configured to form a second seal on the film 21 at the second open edge of the semi-hermetic package, thereby forming a hermetic package 24. In state 204, the product 20 is located within the film 21, and the hermetic package 24 includes a first sealed edge and the opposite second welded edge. The first and second welded edges can also be located not directly opposite each other, for example, in cases where one of the seals is formed at an angle to the longitudinal expansion of the package and / or to the lateral expansion of the other seal. In another embodiment of the present invention, the degassing device 35 assumes the function of the welding device C in that when the gas is removed from the semi-hermetic package, the degassing device 35 performs welding and cutting as described above with respect to the welding device 3 This concept can be visualized based on the embodiment of this invention shown in Fig. 2. Instead of performing operations on only one edge of the packages 24 in state 204 (see on the left side of the degassing device 35), it is possible to imagine that the package 23 is immediately to the right of the degassing device 35 (see package / product directly below the arrow Zba) are welded at the outlet edge of the package, while the elements 351 and 352 are in contact with each other in order to remove the gas from the previous package and to weld this package after removal. Welding, both on the inlet and outlet edges of the gas removal device 35, can be done, in fact, at the same time. 0062) The gas removal device 35 includes a first (or upper) member 351 and a second (or lower) member 352, which may be derived from a first configuration in which the members 351 and 352 are spaced from each other (see Fig. . 1), in the second configuration, in which the elements 351 and 352 are, in fact, in contact with each other (see

Fig. 2). In some embodiments of the present invention, the elements 351 and 352 are, in the second configuration, in contact with each other along the perimeter of the elements 351 and 352, except that at least one opening is formed between the elements 351 and 352. In cross section,

taken along a horizontal plane (that is, a plane parallel to the horizontal working surface of the packaging apparatus 1, for example, on the upper surface of the belt conveyor 30), the elements 351 and 352 may have, in fact, a rectangular shape. Elements 351 and 352 are configured to define, in a second configuration, a vacuum chamber 353. In FIG. 1 and 2 show elements 351 and 352 and vacuum chamber 353 (vertical; see above in relation to horizontal) in cross-section. Thus, the front and rear side walls (ie, walls parallel to the display plane) are not shown in order to represent the interior volume of the vacuum chamber 353.

II0063| As for Fig. 1 and 2, the packaging machine 1 further includes a control unit 50. This control unit is connected (separate connections are not shown for simplicity) to one or more components of the packaging machine 1, including the loading station, the welding device 3, the welding elements and cutting 31 and 32, a device for moving 30, elements 351 and 352, and a pumping device 34.

The injection device 34 can be provided to fill the inner volume of the packaging film 21 with a shielding gas or gas mixture. The control unit 50 is additionally connected to a gas removal device 35 where the gas is removed from the semi-packaged products in state 206 and where they are subjected to welding (and thus brought to state 204). 0064) The control unit 50 can also be connected to additional components, such as a hot air supply device or a shrink tunnel 33, where the film material around the packaged products 20 in the state 204 can be further subjected to shrinkage after the product has been brewed. It should be noted that the degassing device 35 may include any degassing device known in the art. In Fig. 1 and 2, the separate connection lines between the control unit 50 and other components are not shown for simplicity.

It is clear that the packaging apparatus 1 may include a conventional connection device for connecting the control unit 50 to other components, for example, electrical, optical or other connections and/or outputs.

II0065| The control unit 50 may be configured to control the transportation of products 20 along a predetermined path, for example by controlling an electric motor included in the moving device 30 in accordance with

From step motion or according to continuous motion. This control unit can also control the actuators of the various components as described below, for example to form transverse seals on the tubular film, or to actuate the elements 31, 32, 351 and/or 352. 0066) Unit control 50 may include a digital processor (CPU) with a memory module (or memory modules), an analog circuit, or a combination of one or more digital processing units with one or more similar processing circuits. In this description and in this claim, it is noted that the control unit is "configured" or "programmed" to perform certain steps. This can be achieved in practice with the help of any devices that provide for the possibility of configuration or programming of the control unit. For example, in the case of a control unit that includes one or more processors, one or more programs are stored in the corresponding memory. This program or programs contain instructions which, when executed by the control unit, cause the control unit to perform the actions described and/or declared in connection with that control unit. Alternatively, if the control unit is a similar type of unit, the control unit circuitry is intended to include circuitry that is configured to, in operation, process electrical signals, such as to perform the control unit operation steps disclosed herein.

I0067| The control unit 50 is connected to the vacuum device (not shown) and is configured to send and/or receive signals to/from the vacuum device. The control unit 50 may be further configured to control the vacuum device to provide an internal vacuum gauge pressure in the vacuum chamber 353. To this end, the control unit 50 may be configured to control the power that drives the vacuum pump attached to the vacuum chamber 353. 0068) The control unit 50 can be configured to control the transfer device 30. For example, the control unit 50 can be configured to increase or decrease the operating speed of the transfer device 30. The control unit 50 can be further configured to control the operating speed of the transfer device 30 depending on the position of the products 20 in relation to the various components of the packaging apparatus 1 (for example, in relation to the device for bo welding C or the device for removing gas 35).

0069) The control unit 50 can additionally or alternatively be configured to control the elements for welding and cutting 31 and 32. The control unit 50 can additionally be made with the possibility of controlling the elements for welding and cutting 31 and 32 depending on the position of the products 20 in relation to to the vacuum device and/or the welding and cutting elements 31 and 32. For example, the control unit 50 can be configured to activate the welding and cutting elements 31 and 32 depending on the position of the products 20 and/or the tubular film 21 in relation to the output hole and / or elements for welding and cutting 31 and 32. 00701 In particular, the control unit 50 can be made with the possibility of controlling one or more components depending on the signals that are sent to other components and / or received from these components. For example, the control unit 50 can be made with the possibility of controlling the activation of one or more components depending on the position of the products 20 and/or the tubular film 21 in relation to other components of the packaging apparatus 1. Thus, the control unit 50 can activate, for example, welding and cutting elements 31 and 32, when the two following products 20 are in the state 20a, so that a first seal is formed between these two products 20 on the film 21, and the film is cut accordingly.

I0071| After forming the first seal and cutting the film 21, the semi-hermetic packages 23 are moved along the direction of movement of the Zba on the packaging machine, in the direction of the gas removal device 35 and through it. In FIG. 1, the elements 351 and 352 are in their first configuration in which the semi-hermetic package 23 can move through the open vacuum chamber 353. Before the semi-hermetic package 23 exits the degassing device 35, the semi-hermetic package 23 is positioned so that its the second open edge is at least partially inside the open vacuum chamber 353. In more detail, this ensures that the respective product 20 contained in the semi-hermetic package 23 as well as the non-ending section of the film 21 at the second open edge of the semi-hermetic package 23 are outside the open vacuum chamber 353, while the end portion of the film 21 at the second open edge still remains inside the open vacuum chamber 353.

As a result, the intermediate section of the film 21 on the second open edge of the semi-hermetic package

Zo and the extension between the non-end and end sections are located between at least one section of the elements 351 and 352.

I0072)| Elements 351 and 352 are now reduced to their second configuration, in which elements 351 and 352 are in substantially hermetic contact with each other, thereby defining a closed vacuum chamber 353. The contact between elements 351 and 352 is essentially hermetic (e.g., air-tight) except for the elongated opening in which the elements 351 and 352 come into contact with the intermediate area of the second open edge of the semi-hermetic package 23 without forming an air-tight seal along this opening.

I0073| This configuration contributes to at least the following effects when removing gas from the vacuum chamber 353. On the one hand, the flow of gas through the opening in the direction of the inner volume of the vacuum chamber 353 is formed between the opposite surfaces of the elements 351 and 352 and the corresponding surfaces of the intermediate section of the second open edge, placed between elements 351 and 352. This gas flow causes the adjacent film layers at the second end of the semi-hermetic package 23 to allow and/or maintain, in effect, a spaced configuration (ie, opposite film layers are drawn away from each other). On the other hand, the gas is sucked not only from the outer vacuum chamber 353 and the semi-hermetic package 23, but also from the inner volume of the semi-hermetic package 23, as a result of which the air is removed from the semi-hermetic package 23. Generally, the gas sucked from the outside is air, and the gas drawn from inside the semi-hermetic package is a shielding gas or a mixture of gases such as CO.' This process is described in more detail below.

I0074| When the gas has been removed from the semi-hermetic package 23, a welding device, usually included in the degassing device 35, forms a second seal at the second open edge, thereby hermetically closing the package and converting the semi-hermetic package 23 into a hermetic package 24, which contains product 20 in state 204 (see leftmost position in FIG. 2) and from which virtually all internal gas has been removed. Alternatively, the outer portion of the excess film material of the second edge (which is now sealed) is cut away from the sealed package 24. 0075) Referring to FIG. 1 and 2, the transfer device 30 may include one or more belt conveyors 30. The one or more belt conveyors are configured to transport products 20 in states 20a, 2060, and 204, such as packages 22, 23, and 24, because along a predetermined path through the packaging machine 1. For example, the packaging machine may include several belt conveyors 30 (for example, three, as shown in Figs. 1 and 2). The first belt conveyor 30 is made with the possibility of transporting products 20 and / or the film 21 to the elements for welding and cutting 31 and 32. The second belt conveyor 30 is made with the possibility of transporting products 20 and / or packages 22 and 23 after the elements for welding and cutting 31 and 32. And the third belt conveyor is made with the possibility of transporting packages 24 after the device for removing gas 35.

I0076) Fig. 3 shows a cross-sectional view of a section of the gas removal device 35 according to this invention. Typically, the internal volume of the vacuum chamber 353 and the ambient atmosphere (for example, around this chamber and / or semi-hermetic packaging 23) are connected by one or more channels passing along or near the opening 354 and through it. In this drawing, various regions of the second open edge of the semi-hermetic package 23 are shown as an end region 236, an intermediate region 234, and a non-end region 232. It should be noted that the term "end" refers to the outer region of the film 21 on the second open edge of the semi-hermetic package 23, which has been cut from the continuous film 21 and which has not been welded (see the description of Figs. 1 and 2 above). Fig. 3, 4 and 5 are not to scale for simplification. In general, the height of the hole 354 is typically between 0.3 mm and 1 mm, or about 8 to 20 times the thickness of one layer of the film 21. In some embodiments of the present invention, the height of the hole 354 is 0.8 mm, 0 .5 mm or 0.4 mm. The film 21 usually has a thickness in the range of 30 μm to 60 μm, preferably in the range of 40 μm to 55 μm, most preferably in the range of 45 μm to 52 μm.

I0077| As shown in Fig. 3, elements 351 and 352 come into contact with the intermediate area 234 of the second open edge without forming an airtight seal between the inner volume of the vacuum chamber 353 and the surrounding atmosphere. Channels between these two volumes (ie, between the volume inside the vacuum chamber 353 and the volume outside it) can be formed mechanically between the elements 351 and 352 and the non-end section 232, the intermediate section 234, and/or the end section 236 in order to ensure a possible flow of air due to the pressure drop created by the removal of gas from the vacuum chamber 353.

In other words, gas or air 3-l outside the semi-hermetic packaging can pass between elements 351 and 352 and the infinite section 232 (channels SI), between elements 351 and 352 and

From the intermediate section 234 (channels C2), and / or between elements 351 and 352 and the final section 236 (channels C3). It should be noted that the individual distance between the channels does not have to be identical on both (eg, top and bottom) sides of the film material of the second open edge. For example, the size (e.g., height) of channel C2 between member 351 and intermediate section 234 (ie, channel C2 on the upper side of intermediate section 234) need not be identical to the size of channel C2 between member 352 and intermediate section 234 (ie, channel C2 on the lower side of the intermediate section 234). Due to several effects (eg, gravity, vortices, non-identical pressure values and/or pressure changes) acting on the flexible film material, the dimensions of the channels can change before, during and after gas removal. The same applies to channels C1 and C3. In addition, the distance between the film material may vary along the length of the opening 354, for example, due to the wavy shape of the film material at the second open edge of the semi-hermetic package.

I0078| The width of the opening 354 may vary depending on the application and is preferably intended to ensure that the product size matches the product width or a multiple thereof, in addition to some tolerance. This means that the vacuum chamber 353 can be sized to match the width of the product in that the opening 354 generally matches the width of the film 21 at the second open edge (when brought into a flattened configuration as shown in Figures 3 and 4 ), while the width of this hole should be slightly larger than the width of the film, in order to allow for positioning tolerances or manufacturing tolerances in the packaging process. In addition, it should be avoided to have large areas of aperture 354 unoccupied by the film material due to the loss of resulting resistance to gas flow in areas adjacent to the film material and subsequent loss in gas flow through the aperture in areas occupied by the film material. In view of the above, it is possible to remove gas from two or more semi-hermetic packages 23 simultaneously by providing a vacuum chamber 353 (and thus opening 354) having a width that is a multiple of the package width or greater (e.g., up to 33 95 wider, and in some variants of the embodiment of this invention by 25 95 wider). In some examples, gas from three or more semi-hermetic packages 23 may be removed in parallel in a gas removal device having a working width of up to 1000 mm (ie, having a 1000 mm opening). In some embodiments of the present invention, the gas removal device has a working width (ie, the opening has a width) of 900 mm. In other embodiments of this invention, it has a width of 450 mm. As for the hole area,

occupied by the material of the film, the second edge of a row of semi-hermetic packages may occupy 70-90 95 of the hole, preferably 75-80 90 of the hole. 00791 The various effects contributing to the removal of gas from packages are explained in more detail with reference to FIG. 4 and 5. Figure 4 shows a cross-sectional view of a section of the gas removal device 35 according to the present invention, illustrating a specific profile of the end sections of the elements 351 and 352, as well as a schematic representation of the gas flow. One of the key challenges in degassing semi-hermetic packages is to ensure that the open edge of the package is open enough to facilitate gas absorption from the interior of the package.

In some cases, the film material tends to adhere to the adjacent film material, thus, in effect, temporarily closing the open edge of the semi-hermetic package and preventing gas removal from the package. In other cases, the film material is partially adhered to the adjacent film material, thereby reducing the size of the opening(s) in such a way that gas absorption from within the semi-hermetic package is at least partially impaired. 00801 One way to separate opposite layers of film, or to avoid sticking opposite layers together, is to create a transition from a relatively high-pressure, low-velocity zone (shown as HP//M at the top left of Fig. 4) to a relatively low-pressure, high-velocity zone (shown as I R/NM), or vice versa, and, alternatively, back again (shown as

NR/LM right). At the same time, the transition from high to low pressure (or vice versa), as well as the transition from low speed to high speed (or vice versa) in combination with agitation of the film material (for example, due to turbulence and / or gas flow) can lead to the fact that the layers of film material that come into contact will cease to adhere and will be separated from each other by the pressure difference of the gas flow, the difference in velocity and/or the action of friction. In addition, the position of the film layers in the opening can affect the properties of the gas flow in a self-regulating manner. For example, if the channel between the film layer and one of the elements 351 and 352 becomes smaller (or larger), the pressure and the gas flow rate through this channel change accordingly, and thus this can in turn affect the position of the film, changing , thereby, the size of the channel.

I00811| The gradient of pressure/velocity changes in the transition between the HP/LM and GR/NM zones can be

Zo is changed by giving the edges 0, E, p" and / or E' the appropriate profiles. Changing the shape of the edges

О, 0, Е and Е" affects the gas flow in the respective zones and can, for example, promote or prevent stratification of the gas flow or promote or prevent vorticity. A separate effect can result from the effect of the respective shapes on the gas flow (for example, pressure, velocity , direction, etc.) The edges 0 and 02" denote the inlet edges in the drawings, while the edges E and EE" denote the outlet edges, referring to the gas flow when the gas is removed from the vacuum chamber 353. As shown in Fig. 4, the edges O, E, BF' and ER" can have, in fact, a rounded shape defined, for example, by a radius of 1 to 5 mm, in some variants of the embodiment of this invention preferably 2 mm or 2.5 mm. It should be noted that the edges 0, Е, р" and Е" can have the same or different shapes in the sense that, in particular, the input edges О and Ор" can have a different shape than the output edges Е and ПЕ", but also in that the edges O or E of the element 351 may have a different shape than the edges C" or E" of the element 352.

I0082| Figure 5 shows an isometric view of a section of the gas removal device 35 according to the present invention. This drawing shows a specific profile of elements 351 and 352. Parameters characterizing elements 351 and 352, as well as opening 354, include: depth C, height B, width A, angle C, and radii 0, E, and ER. The opening 354 has a height B that is 1 mm or less, preferably 0.4 to 0.8 mm (eg, 0.4 mm, 0.5 mm, or 0.8 mm).

In addition, the opening 354 has a width of 1000 mm or less (eg, 900 mm), preferably 500 mm or less (eg, 450 mm). The hole 354 also has a depth of 50 mm or less (eg, 45 mm), preferably 20 mm or less (eg, 20 mm), and more preferably 12 mm or less (eg, 12 mm). The shape of the leading edge O is based on a curvature defined by a radius of 5 mm or less, preferably 2.5 mm or less (for example, 2.5 mm or 2 mm). The shape of the edge E is based on a curvature defined by a radius of 50 mm or less (eg 50 mm), preferably 30 mm or less (eg 30 mm). The slope of the edge E can be present (ie, the corresponding radius is greater than 0) or not present (ie, the corresponding radius is equal to 0).

The shape of the output edge E is based on a curvature defined by a radius of 10 mm or less (eg 9 mm), preferably 5 mm or less (eg 2 mm). Corresponding edges 0", E, and/or E (not shown in the drawing) associated with element 352 may have the same properties as described above with respect to edges OO, E, and E, although the individual values should not be identical (for example, edge O is based on a radius of 2.5 mm, and edge p" is based on a different radius). The thickness H refers to the thickness of the film material, where H means the thickness of two layers of film material, since the open edge of the semi-hermetic package, as described, includes at least two layers of film material. The width of the second open edge of the semi-hermetic package 23 or package 24 can be determined as a percentage of the value of the parameter A in relation to the width A of the opening 354. The second edge of the package 23/24 can have a width of, for example, 70-90 95 of the value of the parameter A, preferably 75 -80 95 from the value of parameter A.

I0083| Another effect which occurs mainly with elements 351 and 352 having profiles as described above and with reference to FIG. 5, refers to the characteristics of the gas flow passing through the hole and along the profiles of the elements 351 and 352. It should be noted that the cross-section of the hole is not constant along the depth C of this hole (see "C" in Fig. 5) and, in particular, increases from the inclined edges E and E towards the exit edges E and E". The gas flow along the surfaces of the elements 351 and 352 tends to follow the shape of the surfaces due to viscous effects between the gas flow and the adjacent surfaces and also due to the Coand effect.

The same effects occur between the gas flow and the surfaces of the packaging film material 23.

Since the gas flow between the film material and, for example, the element 351 tends to follow the surfaces (ie, the surface shape) of both the film material and the element 351, the gas flow must expand and slow down, thereby applying a force to both surfaces directed in gas flow direction. In other words, the gas flow will attract both the film and the corresponding element towards each other. Since the elements 351 and 352 are fixed immovably in their respective positions, in fact, the layers of film material at the intermediate and end portions of the second edge are separated from each other. This partition action forms and/or maintains a channel extending from the interior volume of the package toward and through the second edge through which gas can be removed from the interior of the package.

I0084| Individual parameters to achieve the above effects vary depending on the specific application. For example, a thicker film material may require a different pressure drop gradient than a thinner film material. In addition, the values of different pressures and gas flow rates are also decisive factors. Table 1 of examples below illustrates various combinations of parameters that have been shown to be effective in relation to the first embodiment of the present invention described above. In these examples

The opening of the treated semi-hermetic packages was provided and effective gas removal from the packages was achieved.

In general, the described method and apparatus can be used in conjunction with a large number of known film materials. In some examples, the film materials used have the properties listed in the following Table 2 (0 means longitudinal direction, TO means transverse direction). It should be noted that these films are only examples that demonstrate the applicability of the described method and apparatus.

In general, the components work in the same way as described above in relation to the first embodiment of the present invention and as shown in FIG. 1 and 2, unless otherwise specifically stated below in this document. The same item numbers in Fig. 6 and 7 denote components corresponding to those depicted in Figs. 1 and 2. Unless otherwise stated, such components have the same functions and properties as described above.

I0086)| Elements for welding and cutting 31 and 32 in the second embodiment of this invention are made with the possibility of forming not only the first seal on the tubular film 21, but also the second seal. Thus, the products 20 placed inside the tubular film 21 leave the welding device C in the state 20c, namely in the hermetic package 24" (instead of the state 2065 and in the semi-hermetic package 23). The hermetic package 24! differs from the hermetic package 24 in that , that the gas present in the package 247 has not yet been removed. As shown, the moving device 30 moves the packages 24" towards and through the degassing device 35. The degassing device 35 operates essentially similarly to that described above, although it is adapted to process sealed packages in the manner described below. After the package 24" has been degassed, thereby converting the package 24" into a sealed (gas-removed) package 24, the transfer device 30 moves the packages 24 away from the degassing device 35. (0087) As can be seen in FIG. 7, the hermetic packages 24 are placed in relation to the vacuum chamber 353 in such a way that after bringing the elements 351 and 352 into their second configuration, the second (hermetically sealed) edge of the package 24" comes into contact with the elements 351 and 352 in such a way that the infinite section the second edge is located outside the vacuum chamber 353, the intermediate portion of the second edge is in contact with the elements 351 and 352, and the end portion of the second edge is located inside the vacuum chamber 353. This arrangement is basically identical to that described above with respect to the first embodiment of this of the invention and semi-hermetic packaging, except that the second embodiment of this invention is made with the possibility of processing hermetic packages.Detailed information about the removal process is described in more detail with reference to Fig. 8-10.

I0OO88) Figure 8 shows a cross-sectional view of a section of a device for removing gas according to this invention. Elements 351 and 352 contact the welded edge of the hermetic package 24" in the intermediate region of the second edge. It should be noted that the non-end (232), intermediate (234) and end (236) regions of the second edge of the hermetic package are as shown in relation to the semi-hermetic package 23 in Fig. 3. For simplicity, these areas are not shown in Fig. 8. When the members 351 and 352 are brought into their second configuration, the end section of the second edge as well as the rest of the package 24" (outside the vacuum chamber 353) expands slightly due to the gas present in the intermediate region of the second edge, which is pushed outwards in the direction of both the end region and the non-end region of the second edge. In addition to the components described above, the vacuum chamber 353 may further include a first 355 and a second 356 fastening elements that come into contact with the uppermost part of the end portion of the second edge. This may be done to rigidly hold the end section in position within the vacuum chamber 353.

(0089) A punching device 359 is engaged to provide the end portion with an aperture 241, thereby allowing the potential passage of gas from the interior volume of the package 24" into the vacuum chamber 353. In general, any punching device can be used here , suitable for punching holes in the end portion of the second edge, such as a hole punch (which, for example, forms an effectively circular hole by punching or punching), or a heating wire of a suitable shape (such as a horseshoe-shaped heating wire, which forms a suitable, effectively , a round hole by thermally cutting the film).Devices for punching holes are preferably made with the possibility of providing the end section of the second edge with a hole, which prevents (subsequent) tearing of the film material, which can happen, for example, when forming a simple (linear) cut or hole, which has sharp corners. When the gas is removed from the vacuum chamber 353, the end section expands (see outwardly directed double arrows in Fig. 8) due to the pressure difference between the internal volume of the package 24" and the internal volume of the vacuum chamber 353.

The expansion of the end section causes the film material of the second edge to maintain a spaced configuration, thereby ensuring that the gas inside the package 24" can flow towards and through the non-end section, the intermediate section, and the end section of the second edge, before it is drawn through the aperture 241 and into the vacuum chamber 353 as shown by the dotted arrows. In this way, the gas is removed from the package 24", which is then brewed using a suitable welding device (not shown in Fig.8). The welding apparatus may include welding blades as known in the art (eg, similar to welding and cutting elements 31 and 32) and may be incorporated, for example, in elements 351 and 352, or may be provided as separate units. outside the vacuum chamber 353, made with the possibility of welding the package 24" and cutting off the outer part of the second edge from the package 24", thus providing a sealed package 24 from which the gas was removed (see Fig. 6). It should be noted that the punching of the holes in the final section can be done, alternatively, after the gas removal has started and while the removal is in progress. In this case, the expansion of the end portion - resulting from the pressure difference and whether or not the aperture 241 is present - can serve to counteract the action of the punch or other hole-punching device, thereby contributing to

With accurate and reliable placement of the device for punching holes and creating an aperture 241.

I0090| In Fig. 9 and 10 show a cross-sectional view of the third embodiment of the gas removal device according to the present invention. Fig. 9 and 10 illustrate one of the advantages of the present invention, as well as additional components associated with the vacuum chamber 353.

Product 20, as shown in Fig. 9 and 10, is depicted as a much larger object than in the remaining drawings. It should be noted that the size of the vacuum chamber and thus the opening 354 simply limits one dimension of the potential size of the products to be processed, namely the width of the package. As shown in Fig. 9 and 10, the size (e.g., length) of the product 20 does not affect the degassing process because only a portion of the sealed (or non-sealed) edge of the package, rather than the entire product, must fit into the vacuum chamber 353. Additionally, the height of the product 20 exerts only a slight effect on the gas removal process, which is that the working height of the members 351 and 352 and the gap between these two members 351 and 352 can be adjusted accordingly when these members are in the first configuration.

I0091| In Fig. 9 shows members 351 and 352 in their first configuration, which allows the package 24" to be positioned such that the non-end, intermediate and end portions of the welded edge of the package 24" can be positioned as described above. In addition, the elements 351 and 352 are respectively associated with the cutting devices 357 and 357 and the welding devices 358 and 358'. Adjacent to the cutting devices 357 and 3577, the members 351 and 352 are curved to engage the intermediate portion of the second edge of the package 24". The welding devices 358 and 358' are located adjacent thereto. (0092) In drawings 11A to 111 shows a cross-sectional view of a third embodiment of a degassing device and associated moving device according to the present invention, together with various stages of a degassing method according to a third embodiment of the present invention. - from right to left, respectively Fig. 1, 2, 6 and 7. In Fig. 11A, the elements 351 and 352 are in the first configuration so that the hermetic package 24 can move along the elements 351 and 352 to a position in which the end section of the package 24" because located between elements 351 and 352, but where the product is located outside the zone,

occupied by elements 351 and 352. In Fig. 118 illustrates an optional step of adjusting the transfer device 30. In some embodiments of the present invention, the transfer device 30 can be adjusted to facilitate the efficient movement of the packages through the packaging apparatus while assisting in the positioning of the packages in relation to the elements 351 and 352. As shown in this drawing, the transfer device section can assume a transport configuration in which packages can be moved through device 35 and a degassing configuration in which the package is positioned relative to members 351 and 352 to facilitate the removal of gas from of this package. In Fig. 11C elements 351 and 352 are brought into the second configuration, and as shown in FIG

Fig. 110, the cutting device 357 is activated to cut the excess film material from the end portion of the package, thereby opening the package again.

In fact, at the same time that the package is opened (ie, shortly before or after), the chamber 353 is evacuated, so that a pressure difference is formed between the internal volume of the chamber 353 and the external atmosphere. In Fig. 11E, it can be seen that the excess film material is dumped into a receiving container (or otherwise disposed of) and that the gas is removed from the interior volume of the package 24" (the amount of residual gas between the film and the product 20 is shown to decrease). As a result, as the gas is removed, the packaging film 24" approaches the product 20. In FIG. 11E shows the final stages of degassing when the film is in close contact with the product 20 and the gas from the package 24" has actually been degassed.

After this, the vacuum of the chamber 353 is stopped, and the package 24" is re-welded with the help of the welding devices 358 and 358. In Fig. 1155, the welding devices 358 and 358' are disconnected, and in Fig. 11H, the elements 351 and 352 acquire the first configuration ( i.e. chamber 353 is open), thus releasing the 24" package. Alternatively, the transfer device section 30 is adjustable to move the package 24" further and/or to receive the next package. Fig. 111 shows how the next package is moved between the members 351 and 352 in their first configuration and thus through the open chamber 353 to be placed as described above. The process then begins again with the next 24" package as described above.

I0093| Fig. 12 shows an isometric view of the third embodiment of the packaging apparatus according to this invention, using a device for removing gas 35", which has two vacuum chambers 353", arranged in parallel. This degassing device 35' of the packaging apparatus 1" includes two vacuum chambers 353 located on both sides of the feed conveyor 35. As shown in Fig. 12, products 20 can be introduced into the degassing device 35' along the direction of movement Zba by means of a feed conveyor, for example in the form of "pillow" packages (ie, packages 24), preferably inflated with an inert gas and sealed at both ends, which have not yet been subjected to a gas removal procedure; see also the description of Figures 6 and 7, given above). The control unit 50 is made with the possibility of controlling the intermediate transverse conveyor Z0t for receiving packages 24" using the supply conveyor Z0i along the direction of movement Zba and moving packages 24" selectively or to the left along the path Zobach-! or to the right along the path Zba-i, respectively, to additional transverse conveyors Z0I or Zog.

A corresponding vacuum chamber 353" is located on both sides of the intermediate transverse conveyor Z0t. (0094) The vacuum chamber 353" structurally and functionally corresponds to the vacuum chambers 353 as described above. Thus, vacuum chambers 353" can include elements 351 and 352" and can be made with the possibility of opening and closing (not shown in

Fig. 12 for simplification), as detailed above. Additional components, for example, actuators, made with the possibility of moving elements 351! and / or 352", which are not shown on

Fig. 12 for simplification. The packages 24", as they travel along paths Zba-! and Zba-g, can be moved to laterally introduce the inlet edge of the package into the open vacuum chambers 353. The vacuum chambers can then be closed and vacuuming can be performed as described above. Thus, these two vacuum chambers can operate alternately (or, in fact, in parallel and / or independently of each other), and during each operating cycle of the corresponding vacuum chamber 353! (eg, opening, introducing the leading edge of one or more packages, closing, vacuuming, opening again), one or more packages 24" can be vacuum pumped with a corresponding (eg, left or right) vacuum chamber 353". e.g. to account for different vacuum time values, different size 24" packages, etc. 0095) In fact, when introduced (e.g. at the same time or directly before / or after) the entrance edge of the package 24" into the opening (see state 20s in Fig. 12), the film material at the inlet edge may be perforated or punctured to facilitate further gas removal. This perforation can be performed using perforation rollers 360 (see

Fig. 12A and 128). Once the inlet edges of the packages are introduced into the vacuum chamber 353", gas or air from the interior volume of the package can be evacuated while closing the vacuum chamber 353 as described above. When the gas evacuation is complete, a welding and cutting operation is performed as described above to in order to release currently vacuumed packages 24" (see state 20a in Fig. 12) from the vacuum chamber 353.

I0096) In Fig. 12A and 128 show detailed views of the gas removal device shown in FIG. 12. The control unit 50 in working condition is connected to the intermediate transverse conveyor ЗОт, the left transverse conveyor Z0i and the right transverse conveyor Зокг.

The intermediate cross conveyor is controlled to receive packages and to move packages laterally in any direction and onto the appropriate cross conveyor (for example, Z0i or Z0g). The lateral cross conveyors are operated to receive the respective packages and to move their leading edge into the respective crimper 360 and through it and into the respective open vacuum chamber 353", as described above. The crimper 360 pierces the respective package and the package is vacuumed, in while the perforated inlet edge of the package is located inside the vacuum chamber 353, the film is extended into the vacuum chamber 353 through the opening. After the gas is removed, the corresponding vacuum chamber 353" is opened and the packages 24" are moved further along the paths Zba-I and Zba-i, respectively. and back in the direction of the intermediate cross conveyor З0t and the unloading conveyor 30o in order to be placed in the output zone of the packaging machine 1".

I0097| The pressure device 360 may include pressure rollers having protrusions 360' on the outer surface of the roller and which, in combination with notches 360", present on the opposite surface, are configured to perforate the film 21 that is fed to this pressure device 360. As shown , the pressing device 360 can be implemented as a set of rollers located opposite each other, having, for example, projections 360" and recesses 360" (alternatively, also any combination of projections and / or recesses made with the possibility of forming one or of several holes, see also above.) It should be noted that they can also

Other devices for perforating the film 21 may be used (for example, heating wires as mentioned above, or knife rolls designed to make cuts along the upper edge of the package), as long as it is ensured that the seal formed by the film 21 at the inlet edge of the package 24" , has been disrupted to facilitate gas removal as detailed above. 0098) In some embodiments of the present invention, several post-processed packages are alternately directed into vacuum chambers 353" such that each vacuum chamber 353" receives, for example, every other package in a series of packages (alternatively, any number of later processed 24" packages - for example, C - can be directed into one of the vacuum chambers 353! for vacuuming). Each vacuum chamber 353" can be sized and configured to be able to handle multiple packages at a time, for example, from 2 to 5 packages, preferably at least C packages, as shown in FIG. 12.

Device for vacuuming in the packaging machine 1! has a modular structure that allows for two or more vacuum chambers 353" to be used simultaneously. Such a modular design can prevent or alleviate a bottleneck situation where the packaging machine 1" can only operate at the speed of its slowest device.

I0099| The packaging machine 1 can include a machine of the NEE5 type (horizontal method of continuous packaging). The NEEZ machine may include a belt conveyor 30 for supporting and transporting packages 22 in a horizontal direction. Product 20 can be placed on a surface. This surface may extend virtually horizontally. This surface may include the upper surface of the belt conveyor 30.

Belt conveyor 30 may be a continuous belt conveyor 30. For example, belt conveyor 30 may be suspended between at least two rollers. The belt conveyor 30 can transport the product 20 in a horizontal direction.

ИО1001| Product 20 can be placed in a tray. This tray supports the product 20. The tray may include walls that extend, in effect, vertically from the base of the tray to a height greater than the vertical dimension of the product 20. Alternatively, the height of the tray may be less than or equal to the height of the product 20. The packaging extends around this tray. The tray may include a material selected from the group consisting of polystyrene,

aluminum or other thermoplastic material such as PET or cardboard. The tray can be solid, solid or foam and have any color and shape.

IO101| The package may include a multilayer film 21. The film 21 may include a polyolefin. The film 21 can be a fully co-extruded shrink film 21. The package forms a barrier for gas passing between the inner volume of the package and the outer volume of the package. Accordingly, the environment inside the package is isolated from the environment outside the package. This helps preserve food 20 and avoid contamination. This can be useful in terms of food hygiene. Packaging can provide a barrier to odors or gases. This may be particularly useful when the product 20 is a food product 20. The package may be resistant to misuse by the package.

ИЙО102| The packaging can be transparent or translucent. This allows the customer to see the product 20 through the packaging. For example, the package may include a transparent film 21.

The packaging film may have anti-fog properties. This ensures high attractiveness for consumers. The packaging film may be suitable for printing. This allows you to print labels directly on the packaging.

IO103| The package may be formed from a roll of film 21. The tubular film 21 may be formed by forming a tube from a roll of film 21. The packaging apparatus 1 may include a forming machine configured to form the roll of film 21 into a tube. This forming machine can form a tube by forming a longitudinal seam along the longitudinal edges of the film roll 21. This tube can be formed from two sheets of film 21. In this case, the forming machine forms two longitudinal seals along the opposite edges of the two film rolls 21. 0104) Packaging apparatus 1 may include a pumping device 34. The pumping device 34 is configured to allow gas to be pumped through the tube from the film 21, from which the package is formed. Filling with gas protects this tube from destruction. The gas filling helps to maintain a distance between the product 20 in the tray and the film 21. This helps to improve the hygienic appearance of the film 21 because the film 21 remains unstained by the product 20. The injection device 34 pumps the gas in a longitudinal direction

Out through the tube. The gas used for injection may include about 70 95 oxygen and about 3095 carbon dioxide or other suitably modified atmosphere.

ИО1051 In addition, the injected gas allows the product 20 to be packaged in a modified atmosphere. The gas can help preserve the product 20 by extending its shelf life.

The desired amount of gas inside each sealed package depends on the type of product 20 and the required shelf life.

IO106| The packaging machine 1 may include a heat-shrinking machine, made with the possibility of heat-shrinking the film 21. This heat-shrinking machine may be a shrinking tunnel based on water or air, for example, a tunnel using hot air 33.

The hermetic package 24 shrinks in the heat shrink machine. The shrinking process may include heating the sealed package. The package 24 may be heated to a temperature in the range of about 130°C to about 150°C.

I0107| Before the hermetic package 24 undergoes shrinkage, unwanted gas may enter the hermetic package along with the product 20. In addition, the hermetic package 24 may contain undesirable "dog ears", where the term "dog ear" means a portion of the package that deviates from the product 20 (eg, due to the product 20 not being a regular rectangular prism). After the shrinking process, the "dog ears" and the gas content are reduced. This gives the hermetic package 24 a more aesthetic appearance. In the case of cheese, the cheese can absorb any residual gas that remains in the sealed package 24 after the shrinkage step.

IO108) Product 20 can be food product 20. For example, product 20 can contain meat, cheese, pizza, ready meals, poultry and fish. The product 20 may actually be dry, as in the case of cheese. For some products, such as cheese, there is no need for a tray to hold the cheese. Alternatively, the product 20 may be wet. In this case, it is especially desirable for product 20 to be located in a tray.

ИЙО109| The packaging method according to the present invention can be used to package food products 20 that must have a shelf life of, for example, anywhere from about six days to about 14 days. 0110) The packaging machine 1 preferably includes a machine with a horizontal method of continuous packaging. However, the packaging machine 1 may include other types of continuous packaging machines, such as a vertical continuous packaging machine (MEE5). In a vertical continuous packaging machine, packages 22 are moved through the packaging machine 1 in a vertical direction during the packaging process.

ИО111) In the MEE5 machine, the package can be sealed once to form the bottom edge of the sealed package. The product 20 is then placed in an open-ended package. The upper edge of the package 22 is then sealed to form a sealed package 24". 0112) Although the present invention has been described in connection with what is now believed to be the most practical and preferred embodiment, it is to be understood that the present invention is not should not be limited to the described embodiments, but rather intended to cover the various modifications and equivalent devices included within the spirit and scope of the appended claims.
