Description

Procedure and device for filling a package with a group of individual products, as well as the packaging manufactured in accordance with the procedure and cutout for the top of such packaging

The invention relates to a method for filling a package composed of several parts based on a lower part as a tray and a top part covering it, with at least one group of individual products assembled, where the at least one product group is removed from a product feeding installation by means of the pressing element that accesses them and is placed from the top at the bottom of the tray-shaped packaging, provided with vertical side walls, and where the packaging is provided with the top of the packaging. The invention is also directed to a device for carrying out the procedure, to the packages manufactured according to the procedure as well as to a cut-out of the lid for the formed packaging. The individual products can be for example glasses, boats, cups, rod-shaped bodies in general but also other pieces that can be assembled forming a group to place them on a packing bottom.

It is known to place individual products such as for example closed glasses, in an arrangement of for example two by four glasses in a lower tray-shaped part, that is to say in a box-shaped container, which has a continuous side wall and that it is open upwards, and place on top of this arrangement a top part of the packaging in the form of a U-shaped cover piece. The side arms of such a U-shaped cover are glued from the outside against the bottom wall. It is true that the manufacture that a package that has been filled in this way can be automated. However, the bonding is not desirable. Bonding requires a special manufacturing measure. The lid is torn from the bottom so that the vessels are visible on the bottom that is placed on a shelf for sale. Due to tearing, the packaging may look poor and in particular a printed mention may be damaged or illegible. The realization of a bonded joint also reduces the speed of passage in the continuous production device.

Another known automated filling / packing procedure consists in that a lid piece is placed on a group of products, in particular closed vessels, the group is slid by the lid piece on a flat cut provided with side walls and then They raise the side walls. In particular, in this case too, the upper part and the lower part are glued together or joined using a suitable fixing means. Due to the sliding on a base the product group is prone to damage. Especially suffers the speed of production.

In order to provide as much as possible a full package that saves material without using special fixing means between the top and the bottom, it is known in practice to fill a tray-shaped bottom with vertical side walls with products individual in an arrangement of a standing group and manually place a lid that saves material, which has a U-shaped profile. A cardboard or corrugated cardboard cutout is used for this. Flaps form the side walls that fit between the product group and the tray walls. Insertion requires manual dexterity and is time consuming. This procedure is especially expensive due to the use of labor and the production speed remains relatively low.

The invention sets forth the following objectives. The packaging must be able to be assembled with the bottom, with at least one group of products and with the top through an automated procedure at a relatively high production speed. The volume of devices of a packaging device that performs the procedure should be reduced and the operation of the device should be optimized. The pieces of the packaging must be able to be joined and separated manually without requiring special joining means in order to obtain at the point of sale an attractive presentation sales packaging through the bottom and the individual products grouped inside, without having suffered damage

The process according to the invention consists in combination with the aforementioned process measures, in which at least one group of products and the upper part of the packaging are removed from the part of the product feeding installation. bottom of the packaging forming a movable positioning unit, which moves in a vertical direction by means of the clamping element to assemble it with the lower part of the packaging and to terminate the full packaging provided with the upper part of the packaging, the access of the clamping element to the positioning unit that thus emerges.

A device according to the invention for carrying out the process according to the invention intended to manufacture full packages therefore presents a product feed installation for individual products, a feed installation for lower parts of packages mounted with side and vertical walls, a feeding installation for upper parts of packaging, a packaging unit to place at least one group of individual products fed into a corresponding lower part of the package that has been fed and a withdrawal installation to remove the packages, the installation of packaged in such a way that to form the placement unit, the at least one product group that is supplied by the product feed installation, with at least one corresponding upper part of the packaging presented by the upper part feed installation of emb alaje and the unit of

Placement is placed on the bottom of the packaging to manufacture the finished packaging, filled, closed and endowed with the top of the packaging.

By means of the process according to the invention, a packaging especially according to the invention is obtained. An upper part specially adapted according to the invention to manufacture the full packaging is formed by a cover cutout that has access holes made adapting to the arrangement and position of the individual products of the corresponding product group, which to form the placement unit Each access hole forms a passage for a suction cup connection between the upper face of the individual product and the corresponding suction cup element of a packaging installation.

In accordance with the invention, it is especially achieved that in the course of filling the lower part of the packaging, the upper part of the packaging is added thereto in a safe position and without using special joining means, with high production speed while manufacturing is fully automated and filling the packaging. In accordance with the invention it is essential that the group of products to be packaged and the top of the lid are assembled to form the placement unit. The placement unit that is formed by means of a temporary intermediate packaging by means of the process steps, is prepared and intended to be received by the lower part of the packaging already prepared with the vertical side walls, by placing from above within this part Bottom of packing. The positioning unit that is formed in the course of the process according to the invention is therefore of such a class that the at least one group of products joins the corresponding upper part of the lid forming a transport unit, and the at the same time it moves to place it on the bottom of the packaging. In accordance with the method according to the invention, the positioning unit is formed in such a way that when the access of the clamping means to the positioning unit is released, it is dissolved. This means that the at least one group of products and the upper part of the packaging are no longer joined forming an autonomous packaging unit that can be displaced in height, but together with the lower part of the packaging constitute elements of the full packaging. As a whole, the device according to the invention thus has a relatively simple construction, because the installation installation is prepared to act together not only with the at least one group of products but also with the top part of the packaging that has been of joining with these. The feeding facilities for the lower parts of the packaging and for the upper parts of the packaging are basically known equipment, relatively simple in terms of mechanical technique. In the same way the installation of withdrawal to remove the full packaging forms an installation that acts in a simple and optimal way with the installation of feeding for the inferior parts that have to be filled, when carrying out the packaging and then, and that works with these.

According to an advantageous embodiment of the process, the upper part of the package is joined to form the positioning unit with the at least one product group by means of a clamping element prepared to raise and lower. For this, a phase is foreseen in which access to at least one group of products as well as to the upper part of the packaging takes place simultaneously to move the positioning unit first independently of the lower part of the packaging and then together with this to assemble and replace it. But there can also be another design of the process that consists, for example, in that the upper part of the packaging is simply placed in a phase on the upper face of the product group and thus joined with it to form the positioning unit that can be displace.

Although it is conceivable that a lid plate or a box-shaped lid with a peripheral edge to fit in the lower part of the packaging is provided as a top part of the packaging, a flat lid cutout or cover field in which fins are articulated, the cover field being adapted to the upper face of the corresponding group of products; while keeping the product group out of the bottom of the packaging, the fins are folded down to form a lid space, so that when folded down, the product group is located at least partly inside the lid space . To especially increase the production speed, it is especially advantageous for the fins to be lowered during the course of the placement unit from a position in the product feeding installation to a positioning position above the corresponding lower part of the packaging. The fins can be used to stabilize the group of products when placed or, if necessary, to hold it further. This takes place because when forming and placing the positioning unit, the fins of the cover cutout are folded to join them with the corresponding group of products and held tight against it.

The process according to the invention is preferably carried out in such a way that a cover cut with fins is used which, by means of the clamping element, are lowered so that at least in the finished packaging they become attached to the side walls of the lower part. of the tray-shaped packaging. The process is preferably carried out in such a way that a cover cutout is used that is made of a material such as cardboard, corrugated cardboard or similar material that develops an elastic recovery force when folded, for which its fins are placed after folding them between the group of products and the side walls of the lower part in the form of a tray and are held in such a way that when releasing the clamping element of the positioning unit they become attached against the inner face of the side walls of the lower part due to The strength of recovery.

The last mentioned procedure conveniently comprises the phase in which the fins are bent at an angle greater than 90 °. This process configuration is especially suitable for the packaging to be filled with

at least one group of individual products that are narrowed towards their bottom, the flaps of the lid cutout being folded when manufacturing the positioning unit and forming a lid space with a trapezoidal U-profile, so that they embrace by below the individual products in the free lateral narrowing areas.

To manufacture the positioning unit, the upper part of the packaging is conveniently held by a suction force exerted by the clamping element, and placed above at least a corresponding group of products. To form the positioning unit, the at least one group of products is preferably held by suction force exerted by the clamping element. With a clamping element of this class, the at least one group of products and the upper part of the packaging can be held when moving the positioning unit, at least in a phase where vertical separation is left.

Preferably, an upper packing part is used that has at least one access hole for at least one product suction element of the clamping element that attacks on the upper face of the product group, the positioning unit being held by force suction that acts through the at least one access hole. Preferably, an upper part of the packaging is used, which to produce the installation unit has access holes each assigned to a corresponding individual product, where to form the placement unit each individual product is subject to the suction force acting through the corresponding access hole.

Although it is preferred to form the positioning unit in such a way that its parts are subject with suction force of a clamping element, it can also be provided according to the invention that in order to form the positioning unit the at least one group of products and The at least one upper part of the packaging is maintained additionally or exclusively by exerting pressure on each other.

The refinement of the device according to the invention consists in relation to the aforementioned process embodiments, especially in that a multifunctional head clamping element with suction force and / or a lateral clamping element that preferably acts with pressure force is prepared. A special embodiment consists in that lateral pressing elements are prepared to fold and release the fins of a cover cut that forms the upper part of the packaging for the corresponding group of products. The lateral pressing elements are preferably made in such a way that they fold the fins to form a fence within which the group of products is located in the positioning unit.

An upper part of the packaging of a package according to the invention is also prepared specifically adapted to hold the positioning unit, specifically with a cover cutout that has access holes that are made in accordance with the arrangement and position of the individual products of the corresponding group of products, so that for the formation of the placement unit, each access hole forms a passage to establish a suction joint between the upper face of the individual product and a corresponding product suction element of an installation of packaging. A special adaptation is that the cutout for the cover is made with sections of suction surfaces that are provided between the longitudinal edges of the cover cutout and the access holes located along the longitudinal edge, and that are adapted to the dimensions of the suction surface of the suction elements of the upper part formed by suction cups.

The dependent claims refer to the aforementioned embodiments and other convenient and advantageous embodiments of the invention. Especially convenient and advantageous forms and possibilities of the invention are described in greater detail below using the following description of the embodiments shown in the schematic drawing. These show:

fig. 5A to 5G a clamping element of a device according to the invention in the positions and phases corresponding to fig. 1A to 1F.

In fig. 1F is shown as an exemplary embodiment of a packed package 1 prepared in accordance with the process according to the invention. The packaging 1 comprises a lower part 11 in the form of a tray, with closed vessels placed inside a sheet, as individual products 21, as well as an upper part 12 that covers the vessels. The lower part 11 is made from a rectangular cutout 110 of the lower part that can be seen in fig. 2. In a field of rectangular bottom 114, rectangular longitudinal side walls 111 and rectangular narrow walls 112 are articulated. These are joined between

yes in raised position by means of corner tabs 113, for example by gluing or stapling, to form a peripheral tray wall. One of the narrow side walls 112 is made with less height than the remaining wall areas to form a cutout or a window that allows products to be seen.

The upper part 12 is prepared from a rectangular cover cutout 120 shown in fig. 3. This has a rectangular hole arrangement 121 which, according to the quantity and arrangement of the vessels, is provided with four holes 122. On each longitudinal side of the hole field 122, a rectangular fin 123 is articulated.

The cuts 110, 120 are made of cardboard, corrugated cardboard or a similar material that, when folded, produces an elastic recovery force. The bottom field 114 forms the bottom or support surface for the two times four vessels that as such form a group of products 2. The vessels having a circular section narrow each one by thinning towards its bottom. The orifice field 121 is adapted to the surface of the product group 2 in such a way that the upper face of the product group 2 essentially covers the surface of the lid, the fins 123 being of the longitudinal sides of the product group 2 essentially collapsed downwards by at least 90 ° in the finished packaging 1, being fitted between the edges of the vessels of the longitudinal sides and the longitudinal walls 111 of the lower part 11. In this way the fins 123 rest on the bottom of the packaging. The arm length of the fins 123 is sized such that the hole field 121 almost sits on the vessels.

The cutout of the cover 120 has interlocking projections at the ends of the longitudinal edges prepared to fit into the corresponding grooves of the walls of the narrow sides 112 of the lower part. The upper part of the lid 12 placed can thus be immobilized in the lower part. The interlocking joint can be easily released, especially because the narrow side part of the lower height is slightly stretched outward, in order to free the projections of the small socket in the grooves.

In fig. 1A to 1E are represented five positions, I-V in phases of the manufacture of the packaging according to the process according to the invention.

As you can see from fig. 1A, the cutout of the lid 120 is lowered vertically on the product group 2 of two by four glasses of individual products 21 (glasses) arranged side by side in a horizontal position. In doing so, the orifice field 21 is attached on the upper face of the products 2, or it is kept slightly separated from it, conveniently selectable. Starting from this arrangement and position shown in fig. 1B, which constitutes the first phase of a positioning unit 3 according to the invention, is placed specifically on the lower part of the packaging 20, as shown in fig. 1 C. During the translation, that is, during the transport of the positioning unit 3 to the position above the lower part of the packaging 11, the fins 123 are gradually bending down, forcing them to overcome the elastic recovery force of the cutting material. Finally, the fins 123 are folded with a fold greater than 90 °, such that in accordance with the conicity of the vessels they are laterally holding these below, without necessarily seating them. As can be seen from fig. 1D, the product group 2 becomes located in a space of the lid that on the open front faces presents a U-shaped trapezoidal profile.

The positioning unit 3 descends vertically downwards with the formation and position that had been reached in fig. 1D, outside the lower part of the package 11, to be introduced from above in the vertical direction in the lower part of the package 11. For this, the product group 2 is oriented in exact position to be placed on the bottom of the lower part 11. In fig. 1E the positioning unit 3 has been lowered so that the lower area of the vessels and fins 123 already penetrates the lower part 11. Starting from the position shown in fig. 1E in which the positioning unit 3 is still in the formation according to fig. 1D, the positioning unit 3 continues to descend. In this phase the fins 123 of the positioning unit 3 are free to open due to the elastic recovery force, with the consequence that thanks to the elastic recovery force they settle against the inner face of the longitudinal side walls 111 of the bottom 11.

In fig. 1D and 1E it is especially well observed that the forced folding of the fins 123 with an angle greater than 90 ° and the subsequent elimination of the forced conduction, when the fins 123 overlap with the longitudinal walls 111 of the lower part, constitutes an insertion form Especially simple, efficient and safe in the positioning unit 3, and with it from the upper part 12 in the lower part of the package 11. The full package 1 shown in fig. 9, as described above.

As will be described in greater detail and in accordance with the exemplary embodiment according to fig. 5B to 5F, the upper part of the packaging 12 is maintained in the positioning unit 3 at a fixed vertical separation with respect to the product group 2. For example, it is also possible to place the upper part of the packaging directly on the positioning unit The product group.

A filling device according to the invention as depicted in the exemplary embodiment of fig. 4, comprises installations 5 to 9, arranged in a frame armor 41. The device 4 with its facilities 5 to 9 is made and arranged in such a way that two work / transport lines are formed.

located parallel to each other. In a first line A there is a feed installation of the product 5, and seen behind in the direction of feeding, a feed installation of upper parts 7. In a second line B there is provided a feed installation of lower parts 6, and then, seen in the feed direction, a withdrawal installation 9 for full packages 1.

The product feed installation 5 has, at its end on line A, withdrawal stations 501 and 502 arranged one behind the other. The lower part feed installation 6 and the withdrawal installation 9 are delimited from each other by means of two insertion stations 601, 602, which are arranged one behind the other on line B. The main element of the device 4 is a packaging installation 8 that with a presser installation 80 is assigned to stations 501, 502 and 601, 602. The presser installation 80 is schematically represented only with dashed lines. It comprises a first pressing element 81 assigned to the pair of stations 501, 601 and a corresponding second pressing element 81 which is assigned to the pair of stations 502, 602. The pressing element 81 provided in duplicate will be described in greater detail using the figures 5A to 5G.

The withdrawal station 501, 502 and the insertion station 601, 602 are double stations, such that the two packing stations arranged in pairs 501, 601 and 502, 602 respectively are arranged next to each other. In the packaging installation 8, two groups of two by four individual products 21 are moved from the withdrawal stations 501, 502 in a parallel regime synchronized in time, which are moved from line A to line B and then inserted at the insertion station 601 or 602 respectively.

The product feed installation 5 is carried out with a two-band product feed. The individual products 21 are conducted in parallel along the line A in two tracks by means of a conveyor installation 51 that is not shown in greater detail, to the withdrawal stations 501, 502. In each of the withdrawal stations 501, 502 a group of products 2 based on two by four individual products is formed along the feeding of products on two tracks, and remains ready for withdrawal. The lower part feed installation 6 supplies along the line B, raised packing parts 11, which are placed in the insertion stations 601, 602. The lower packing parts 11 are adapted in size for each receive a group of products 2.

The upper part feed installation 7 comprises a cover trim store 71 that is not shown in greater detail. From this, the cover trim 120 is automatically removed and placed in each withdrawal station 501, 502 in exact position on each product group. The presser installation 80 of the packaging installation 8 then performs for each pair of stations 501, 601 and 502, 602 the displacement and insertion procedure as described above using Fig. 1A to 1F. At stations 601, 602, full packages 1 of line B appear simultaneously and are removed by means of the withdrawal installation 9 by a conveyor belt or other suitable means of transport.

The assembly of the filling device 4 works completely automatically. The device 4 may be formed with drives and equipment known per se. For example, the product feeding installation 5 can be carried out with a modular conveyor belt whose bandwidth is sufficient to feed the individual products 21, in particular the vessels, in more than two tracks. In the same way, the other installations of the device 1 can be equipped with modular assemblies that allow a change of preparation adapting to larger packages.

The product feeding installation 5 may be equipped to group the vessels for the withdrawal facilities 501, 502, for example with a stop that can be moved by a servomotor and that removes the vessels, which groups the vessels into the two tracks shown to form the two packaging groups of two by four glasses. The cover clip storage 71 can be provided, for example, in the form of a motorized central warehouse from which the cutouts of the covers 120 are conducted in a position inclined to the stations 501, 502 by means of a suction installation which is not shown . The transport of the cuts can be carried out by means of conveyors not shown, which are transported, for example, by means of a linear axis of toothed belt driven by servo motor.

The lower part feed installation 6 can comprise, for example, pneumatically driven pushers that are not shown that deliver the lower parts 11 to the packaging installation 8. There, the installation can be in a known way but not shown, such that they are introduced cyclically at the insertion stations 601, 602, two lower parts received 11 by means of a pneumatically operated input barrier in combination with two motorized drive introducer cylinders that work laterally. The pneumatically operated barriers position the lower parts 11 exactly in the filling positions of the insertion stations 601, 602.

In the exemplary embodiment of the device 4 according to fig. 4 two packages I are produced in parallel, with exactly one upper part of the package being added to each product group 2. Depending on the need, the movement or the device can be carried out in such a way that in a group of products, for example, two upper parts of the lid packaging are added.

In fig. 5A to 5F positions I to VI are represented in the process phases corresponding to the phases or positions I to VI of fig. 1A to 1F. In fig. 5A to 5G are also represented essential components of the clamping element 81, which in double version constitutes in turn a component of the pressing installation 80 of the packaging installation 8 that is not represented in greater detail, for the pairs of stations 501, 601 and 502, 602. The clamping element 81 is a clamping element in the form of a head which is equipped with suction elements for covers 811, product suction elements 812 and lateral pressing elements 813.

The suction elements 811, 812 are made as vacuum suction cups, each of which is connected to a pair of vacuum lines 821, 822. The lines 821, 822 extend parallel to the lines A, B of the device 4. The vacuum line 822 and therefore the product suction elements 812 is arranged in accordance with the separations between the vessels of the product group 2. Thus, each vessel of the product group 2 corresponds to a suction element of the product 812. The product suction elements 812 pass through the access holes 122 of the cover 120 cutout so that each one can be placed centered on the glass lid. Therefore, the clamping element 81 comprises in the exemplary embodiment two by four product suction elements 812. Each access hole 122 forms in the corresponding arrangement a passage for a suction connection between the upper face of the individual product 21 and the 822 vacuum driving.

The vacuum line 821 of the cover suction elements 811 is located in each case next to the vacuum line 822 and extends respectively between the adjacent longitudinal edge of the hole field 121 and the access holes 122 located on the side of the longitudinal edge In the exemplary embodiment, three cover suction elements 811 are provided on each longitudinal face following the modular separation of the holes 122. Between the access holes 122 located on the side of the longitudinal edge and the longitudinal edges of the hole field 121, find the edge sections 124 adapted to the dimensions of the suction elements of covers 811 to establish the suction connection (fig. 3).

With the clamping element 81, which comprises the suction elements of covers 811 and the suction elements of products 812, distanced from those in height, it is achieved that when moving the positioning unit the product group 2 and the upper part are maintained of packing 12 with a height separation h (see detail in fig. 5B). For this purpose, another pressing element can be provided that establishes the fixed distance.

According to another embodiment that is not shown, the upper part of the packaging can be placed on the product group in the installation unit. In order to insert the positioning unit or assemble the packaging, it is possible, for example, in addition to a clamping element that holds the product group, a clamping element of the device that assembles the upper part of the packaging with the lower part of the packaging, for example by establishing a sliding joint.

The clamping element 81 is further equipped with lateral pressing elements 813 corresponding to the fins 123 of the cover trim 120. Each lateral clamping element 813 is formed by a bar 824 articulated by means of bent arms 823, which extends to the along the corresponding fin 123 and which in the exemplary embodiment is located in the flat cover cutout 123 in the area of its outer edge. The angled arms 823 that are firmly attached to the bars 824 are rotatably articulated at the ends of a cross bars 825, around pivot axes 826.

In the exemplary embodiment, the clamping element 81 comprises three parallel crossbars 825 that extend in a parallel plane above the vacuum lines 821, 822 that carry the suction cups and have an orientation perpendicular to these pipes.

Vacuum conduits 821, 822 and crossbars 825 form the supporting elements of the clamping element 81, and are firmly connected to each other in a support head of the clamping element 81, in a form not shown in detail.

The presser installation 80 is supported with the possibility of horizontal displacement on a support 42 in the direction perpendicular to the lines A, B. The presser element 81 is housed in the presser installation 80 with the possibility of vertical displacement in height. Both the horizontal movement and the vertical movement of the clamping element 81 can be realized and controlled by means of a servo motor driven linear belt unit, which are not shown. Other suitable arrangements and drives also fit.

As can be seen from fig. 5A, the pressing element 81 is prepared and arranged to be able to remove and first hold the cutout of the cover 120 which is carried horizontally on the extraction station 501 or 502 respectively. In this position 1, the cutout of the cover 120 is in the flat position shown in fig. 1A. It is held by three by two cover suction elements 811 in a horizontal position, properly aligned on the product group 2. The product group 2 is the group that is present for withdrawal at the withdrawal station 501 or 502 respectively .

In position 11, the clamping element 81 has been lowered sufficiently for the suction elements of the product 812 to seat on the lids of the vessels. Vacuum is applied to the conduits 822 so that each vessel of the product group 2 is held and maintained while maintaining this formation. At the same time the cutout of the lid 120 is located with a fixed reduced clearance above the vessels. This separation is determined by a difference in height between the suction elements of the lid 811 and the product suction elements

812. In position II the positioning unit according to the invention is shown in a first phase.

The angled arms 823 are articulated on the crossbars 825 around the pivot axes 826 of a rotation installation that is not shown, which carries a motorized drive element. The motorized swivel joint is such that the bars 824 are articulated with forced conduction in the transverse bars 825 to fold down an angle greater than 90 ° the fins 123 from the horizontal starting position in the flat cover cutout 120 in the direction towards the group of products 2.

In position III, the rotational drive of the lateral pressing elements 813 has been activated, the fins 123 being folded down there first, at an angle of about 45 °. The position III of the fins 123 is reached while the clamping element 81 or the positioning unit 3 is moved from the extraction station 501 or 502 to the insertion station 601 or 602 with a horizontal movement in a direction perpendicular to the lines A, B.

In position IV, the fins 123 of the embodiment example are folded approximately 95 °, so that they settle on the long inclined sides of the product group 2, and therefore hold the vessels below. In this way, the fastening of the vessels in the positioning unit 3 can be complemented in addition to the fixation by means of the product suction elements 812. The bars 824 act as pressure means that hold the group of products 2 by their side longitudinal exerting pressure. It is also possible to imagine that these pressure elements are provided without the provision of the suction cups to form the positioning unit.

In position V, the clamping element 81 has been moved downwards in the vertical direction at the insertion station 601 or 602 such that the positioning unit 3 penetrates with its lower area at the bottom 11. Before the unit of positioning 3 is fully placed inside the lower part 11 the bars 824 of the motorized turning installation are released, turning back to return to the starting position represented in fig. 5A. As described above, due to this, the fins 123 are deployed so that they come to sit inside against the longitudinal side walls 111. To carry out a complete insertion, the clamping element 81 continues down vertically until the vessels settle on the bottom of the packaging. At the same time, the upper part 12 continues to be inserted vertically into the lower part 11 until the fins 123 settle on the bottom of the package. The upper part 12 is then held by the lower part in a firm pressure seat. In fig. 5F position VI has been reached.

For fig. 5G the release of the installation unit 3 can be seen. All the suction elements 811, 812 are disconnected from the vacuum by means of a vacuum system not shown that feeds the suction lines 821, 822, so that they are detached from the vessels or from the upper part of the packaging 12.
