Figure 23 is a top plan view of the machine shown in Figure 22.

With reference to figures 22 and 23, the machine for forming and filling packaging container bodies, globally indicated with the reference number 1, comprises at least one feed line 2 arranged between at least one carton magazine 3 containing a stack 4 of cardboard blanks 5 and at least one exit station of the container body 7, 8, 9, 10, 11 and 12 obtained with at least one of the blanks 5.

More specifically, between the carton magazine 3 and the exit station there are at least one station for picking up the first blank 6a, 6b, 6c, 6d, 6e and 6f from the stack 4 and suitable for placing this on the feed line 2.

Between the carton magazine 3 and the outfeed station there is also a plurality of forming and sealing stations placed in sequence for forming and sealing the first blank 6a, 6b, 6c, 6d, 6e and 6f in the container body 7 , 8, 9, 10, 11 and 12.

According to the invention, along the feed line 2 of the machine 1 there is at least one overturning station of the first blank 6a, 6b, 6c, 6d, 6e and 6f for its rotation substantially by 90 ° with respect to the feed line 2.

Conveniently, along the feed line 2 of the machine 1 there is at least one station for filling the first blank 6a, 6b, 6c, 6d, 6e, 6f and 6g during its forming in the forming and sealing stations.

Advantageously, as will be further described below, the machine 1, according to the invention, is able to pack various ranges of product using various types of packaging with various filling methods in order to obtain a container body selected from the group consisting of: American case with top loading of 7 products, American case with frontal loading of 8 products, American case from open blank 9, wrap around case 10, display case 11, display tray 12 and display tray 12 with lid 13.

An example of the succession of automatic product packaging phases is shown below for each type of packaging listed.

Certain phases that make up the complete packaging cycle, depending on the speed at which the machine has to work understood as packages per minute, can be grouped into a single station or further divided.

In the particular embodiment proposed, the machine 1 is made up globally of seven stations, comprising both those for forming and sealing, and those for filling and overturning.

It should be emphasized that this number can be increased or decreased according to the speed requirements of the machine 1 itself.

Furthermore, the same stations, as production requirements vary, can be reversed or moved forward or backward in carrying out the packaging process itself.

With particular reference to Figures 1 to 3 and Figures 22 and 23, by using the machine 1 described above, it is possible to carry out a process for forming and filling packaging container bodies, particularly of the American crate type with loading from 'high of products.

This process comprises picking up the first blank 6a from the stack 4 from the pick-up station.

Conveniently, in this pick-up phase the first blank 6a is an American cardboard pre-glued on one side but closed on itself in such a way as to define a sheet-like body and in this pick-up step the first blank 6a is opened by contrast or by positive opening in such a way as to assume a substantially tubular shape.

At the same time, the same first open blank 6a is arranged in the first station on a catenary, for example with flights or suction belt or technically equivalent systems, defining the feed line 2 in such a way as to rest on it in correspondence with one of its sides 14 .

Subsequently, again in the first station, the closing of two first right lateral flaps 15 and 16, front and rear, of the first blank 6a takes place in such a way as to form at least part of the bottom of the American crate with loading of the products 7 from above.

In passing from the first station to the second station, glue is sprayed onto these two first right side flaps 14 and 15 previously closed by means of suitable sprayers 17.

In the second station, the closing of two second right side flaps 18 and 19, lower and upper, of the first blank 6a on the two first right side flaps 15 and 16 are closed in such a way as to complete the forming of the bottom of the American box with top loading of products 7.

More specifically, in this phase of closing the two second right lateral flaps 18 and 19, a contrast pad 200 is inserted through the opening of the first blank 6a defined on the opposite side with respect to the aforementioned bottom.

In this way, the thrust applied to the two second right side flaps 18 and 19 is counteracted by fastening them to the two first right side flaps 15 and 16 by means of the previously interposed glue.

In the third station, which in this case coincides with the overturning station, the first partially closed blank 6a is overturned by 90 ° with respect to the feed line 2 in such a way that the aforementioned opening faces the tall.

In the fourth station, which in this case coincides with the filling station, the first blank 6a is vertically filled with products through the opening previously facing upwards.

In passing from the fourth station to the fifth station, two first upper lateral flaps 20 and 21, front and rear, of the first blank 6a opposite the two first right lateral flaps 15 and 16 are closed in such a way as to form at least part of the roof of the American crate with top loading of products 7.

At the same time, by means of suitable sprayers 22, glue is sprayed on the two first closed upper lateral flaps 20 and 21.

Subsequently, in passing from the fifth to the sixth station, two second upper lateral flaps 23 and 24 are closed, left and right, of the first blank 6a opposite the two second right lateral flaps 18 and 19 on the two first upper lateral flaps 20 and 21 in in such a way as to complete the shaping of the top of the American box with loading of the products from the top 7.

In the sixth station the conformation and squaring of the first blank 6a takes place with the crushing of the upper lateral flaps 20, 21, 23 and 24 for their mutual fixing by means of the previously interposed glue.

Finally, in the seventh station, coinciding with the exit station, the ejection of the American crate with the top loading of the products 7 completed takes place.

With particular reference to Figures 4 to 6, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the American box type with front loading of the products.

This process comprises the withdrawal of the first blank 6b from the stack 4 in the withdrawal station.

Conveniently, in this pick-up phase the first blank 6b is an American cardboard pre-glued on one side but closed on itself in such a way as to define a sheet-like body and in this pick-up phase the first blank 6b is opened by contrast or by positive opening in such a way as to assume a substantially tubular shape.

At the same time, the same first open blank 6b is arranged in the first station on a catenary, for example with flights or suction belt or technically equivalent systems, defining the feed line 2 in such a way as to rest on it in correspondence with one of its sides 25 .

Once the first blank 6b has been placed on the feed line 2, the first, second and third stations are only in transit.

This does not mean that in a variant not described in the present process, such transit stations could be used to carry out some of the operations that are carried out in the subsequent stations.

In passing from the third station to the fourth station, a first front right side flap 26 of the first blank 6b is closed in such a way as to form at least part of the bottom of an American crate with front loading of the products 8.

Subsequently, in the fourth station, the other first right side flap 27 rear of the first blank 6b is closed in such a way as to form at least part of the bottom of the American box with front loading of the products 8.

Still in the fourth station, the horizontal filling of the first blank 6b with products takes place through the opening of the first blank 6b defined on the opposite side with respect to the bottom mentioned above.

In passing from the fourth station to the fifth, the closing of two first left side flaps 28, front and rear, of the first blank 6b opposite the two first right side flaps 26 and 27, is closed in such a way as to form at least part of the top of the American box with front loading of products 8.

In passing from the fifth station to the sixth station, by means of special sprayers 29, glue is sprayed both on the two first right side flaps 26 and 27 closed and on the two first left side flaps 28 closed.

At the same time, the closing of two second right side flaps 30 and 31, lower and upper, of the first blank 6b on the two first right side flaps 26 and 27 and of two second left side flaps 32 and 33, upper and lower, of the first blank 6b opposite the two second right side flaps 30 and 31 on the two first left side flaps 28 in such a way as to complete, respectively, the forming of the bottom and the top of said American box with front loading of the products 8.

In the sixth station the conformation and squaring of the first blank 6b takes place with crushing of the side flaps 26, 27, 28, 30, 31, 32 and 33 for their mutual fixing by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the overturning of the American box with frontal loading of the products 8 by 90 ° takes place, with respect to the advancement line 2 so that the roof previously made is facing upwards, and the ejection of the American crate with front loading of products 8 completed.

With particular reference to Figures 7 to 9, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the American box type from open blank.

This process comprises the withdrawal from the pick-up station of the first blank 6c from the stack 4 which, suitably, is an open American cardboard consisting of a single sheet-like element.

At the same time, the same first open blank 6c is arranged in the first station on a catenary, for example with flights or suction belt or technically equivalent systems, defining the feed line 2, in correspondence with one of its sides 34 in such a way as to be substantially arranged U-shaped with the base of said U resting on the feed line 2.

Once the first blank 6c has been placed on the feed line 2, the first, second and third stations are only in transit.

This does not mean that in a variant not described in the present process, such transit stations could be used to carry out some of the operations that are carried out in the subsequent stations.

In passing from the third station to the fourth station, a first front right side flap 35 of the first blank 6c is closed in such a way as to form at least part of the bottom of an open blank box 9.

Subsequently, in the fourth station, the other first right lateral flap 36 rear of the first blank 6c is closed in such a way as to form at least part of the bottom of the American box from open blank 9.

Still in the fourth station, the horizontal or vertical filling of the first blank 6c with products takes place through a first opening of the first blank 6c defined on the opposite side with respect to the aforementioned bottom or through a second opening of the first blank 6c defined on the opposite side with respect to the side 34 .

In passing from the fourth station to the fifth, the closure of two first left side flaps 37, front and rear, of the first blank 6c opposite the two first right side flaps 35 and 36, occurs in such a way as to form at least part of the top of the American box. open blank 9.

Always in the passage from the fourth to the fifth station, the folding of an appendage 39 defined on a lateral face 40 of the first blank 6c takes place and immediately afterwards, by means of special sprayers 38, the glue is sprayed on said appendix 39 and the folding of the upper face 41 of the first blank 6c in such a way as to come into contact with the appendix 39.

In passing from the fifth station to the sixth station, by means of special sprayers 42, glue is sprayed both on the two first right side flaps 35 and 36 closed and on the two first left side flaps 37 closed.

At the same time, the closing of two second right side flaps 43 and 44, lower and upper, of the first blank 6c on the two first right side flaps 35 and 36 and of two second left side flaps 45 and 46, lower and upper, of the first blank 6c opposite the two second right side flaps 43 and 44 on the two first left side flaps 37 in such a way as to complete, respectively, the forming of the bottom and top of the American box from open blank 9.

In the sixth station the conformation and squaring of the first blank 6c takes place with crushing of the side flaps 35, 36, 37, 43, 44, 45 and 46 for their mutual fixing by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the overturning of the American box from open blank 9 by 90 ° takes place, with respect to the advancement line 2 in such a way that the roof previously made is facing upwards, and the expulsion of the American case from open blank 9 completed.

With particular reference to figures 10 to 12, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the wrap around type.

This procedure comprises the withdrawal from the pick-up station of the first blank 6d from the stack 4 which, suitably, is a wrap-around cardboard consisting of a single sheet-like element.

At the same time, the same first open blank 6d is arranged in the first station on a catenary, for example with flights or suction belt or technically equivalent systems, defining the feed line 2, in correspondence with one of its sides 47 in such a way as to be substantially arranged U-shaped with the base of said U resting on the feed line 2.

Once the first blank 6d has been placed on the feed line 2, the first, second and third stations are only in transit.

This does not mean that in a variant not described in the present process, such transit stations could be used to carry out some of the operations that are carried out in the subsequent stations.

In passing from the third station to the fourth station, a first front right side flap 48 of the first blank 6d is closed in such a way as to form at least in part a first side wall of a wrap around case 10.

Subsequently, in the fourth station, the other first right side flap 49 rear of the first blank 6d is closed in such a way as to form at least in part the first side wall of the wrap around case 10.

Also in the fourth station the horizontal or vertical filling of the first blank 6d with products takes place through a first opening of the first blank 6d defined on the opposite side with respect to the first wall mentioned above or through a second opening of the first blank 6d defined on the opposite side with respect to the side 47.

In passing from the fourth station to the fifth, two first left side flaps 50, front and rear, of the first blank 6d opposite the two first right side flaps 48 and 49 are closed in such a way as to form at least partially a second side wall of the box wrap around 10.

Always in the passage from the fourth to the fifth station, an appendage 52 defined on a side face 53 of the first blank 6d is folded and immediately afterwards, by means of special sprayers 51, glue is sprayed on said appendix 52 and the upper face is folded. 54 of the first blank 6d in such a way as to come into contact with the appendix 52.

In passing from the fifth station to the sixth station, by means of special sprayers 55, glue is sprayed both on the two first right side flaps 48 and 49 closed and on the two first left side flaps 50 closed.

At the same time, the closure of two second right lateral flaps 56 and 57, upper and lower, of the first blank 6d on the two first right lateral flaps 48 and 49 and of two second left lateral flaps 58 and 59, upper and lower, of the first blank 6d opposite the two second right side flaps 56 and 57 on the two first left side flaps 50 in such a way as to complete the shaping of the side walls of the wrap around case 10.

In the sixth station the conformation and squaring of the first blank 6d takes place with the crushing of the lateral flaps 48, 49, 50, 56, 57, 58 and 59 for their mutual fixing by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the expulsion of the completed wrap around cash desk 10 takes place.

With particular reference to Figures 13 to 15, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the display case type.

This process comprises the withdrawal from the withdrawal station of the first blank 6e from the stack 4 which, suitably, is an open display case consisting of a single laser-shaped element.

At the same time, the same first blank 6e open on a catenary is arranged in the first station, for example with flights or suction belt or technically equivalent systems, defining the feed line 2, in correspondence with one of its sides 60 in such a way as to be substantially arranged U-shaped with the base of said U resting on the feed line 2.

Once the first blank 6e has been placed on the feed line 2, the first, second and third stations are only in transit.

This does not mean that in a variant not described in the present process, such transit stations could be used to carry out some of the operations that are carried out in the subsequent stations.

In passing from the third station to the fourth station, the closing of a first right side flap 61 in front of the first blank 6e takes place in such a way as to form at least in part a first side wall of a display case 11. Subsequently, in the fourth station the closing of the another first rear right side flap 62 of the first blank 6e in such a way as to form at least part of the first side wall of the display case 11.

Also in the fourth station the horizontal or vertical filling of the first blank 6e with products takes place through a first opening of the first blank 6e defined on the opposite side with respect to the first side wall or through a second opening of the first blank 6e defined on the opposite side with respect to the side 60 .

In passing from the fourth station to the fifth, two first left side flaps 63 and 64 are closed, front and rear, of the first blank 6e opposite the two first right side flaps 61 and 62 in such a way as to form at least part of the second side wall of the display case 11 opposite the first aforementioned side wall.

Always in the passage from the fourth to the fifth station, the folding of the upper appendages 65, both front and rear, commonly known as sidewalks and defined in correspondence with the four corners of the first blank 6e, takes place.

In passing from the fifth station to the sixth station, by means of special sprayers 67, glue is sprayed both on the two first right side flaps 61 and 62 closed, and on the two first left side flaps 63 and 64 closed.

At the same time, a central right flap 68 and two upper right flaps 66 of the first blank 6 are closed and on the right side flaps 61 and 62 in such a way as to complete the forming of the first side wall of the display case 11.

In the same way, a central left flap 69 and two upper left flaps 86 of the first blank 6e are closed, opposite, respectively, to the central right flap 68 and to the two upper right flaps 66, on the two left side flaps 63 and 64 in such a way as to complete the forming of the second side wall of the display case 11.

In the sixth station the conformation and squaring of the first blank 6e takes place with the crushing of the central flaps 68 and 69 and of the upper flaps 66 and 86 for their fixing to the lateral flaps 61, 62, 63 and 64 by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the expulsion of the completed display case 11 takes place.

With particular reference to Figures 16 to 18, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the display tray type.

This method comprises picking up the first blank 6f from the stack 4 from the pick-up station which, conveniently, is an open display tray consisting of a single sheet-like element.

At the same time, the same first open blank 6f is arranged in the first station on a catenary, for example with flights or suction belt or technically equivalent systems, defining the feed line 2, in correspondence with one of its sides 70 in such a way as to be substantially arranged U-shaped with the base of said U resting on the feed line 2.

Once the first blank 6f has been placed on the feed line 2, the first, second and third stations are only in transit.

This does not prevent the fact that in a variant not described in the present process, such transit stations could be used to carry out some of the operations that are carried out in the subsequent stations.

In passing from the third station to the fourth station, a first front right side flap 71 of the first blank 6f is closed in such a way as to form at least part of the support for a first side wall of a display tray 12.

Subsequently, in the fourth station, the other first right side flap 72 rear of the first blank 6f is closed in such a way as to complete the support of the first side wall of the display tray 12.

Also in the fourth station the horizontal or vertical filling of the first blank 6f with products takes place through a first opening of the first blank 6f defined on the opposite side with respect to the first side wall or through a second opening of the first blank 6f defined on the opposite side with respect to the side 70 .

In passing from the fourth to the fifth station, two left side flaps 73 and 74, front and rear, of the first blank 6f opposite the two right side flaps 71 and 72 are closed in such a way as to form the support for a second side wall of the tray display 12 opposite the first side wall mentioned.

In passing from the fifth station to the sixth station, by means of special sprayers 75, glue is sprayed both on the two right side flaps 71 and 72 closed, and on the two left side flaps 73 and 74 closed.

At the same time, a central right flap 76 of the first blank 6f is closed on the right side flaps 71 and 72 in such a way as to complete the forming of the first side wall of the display tray 12.

In the same way, the closing of a left central flap 77 of the first blank 6f opposite the right central flap 76 on the left side flaps 73 and 74 in such a way as to complete the forming of the second side wall of the display tray 12.

In the sixth station the conformation and squaring of the first blank 6f takes place with crushing of the central flaps 76 and 77 for their fixing to the side flaps 71, 72, 73 and 74 by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the ejection of the completed display tray 12 takes place.

With particular reference to Figures 19 to 21, by using the machine 1 described above, it is possible to carry out a process for forming and filling container bodies for packaging, particularly of the display tray type with lid.

This procedure provides the same steps as the procedure just described for the display tray 12 with the difference that the product is wrapped in a second blank 6g and that therefore there are some additional steps in parallel for the production of a lid 13 from the second blank 6g.

More specifically, in a further pick-up station, independent of the feed line 2, the second blank 6g is picked up from a further magazine of cardboard blanks.

Said second blank 6g is an open lid consisting of a single sheet-like element which is arranged on a translator crossing the feed line 2 at one of said forming and sealing stations and, more precisely, at the fourth station of the forming process and display tray filler 12.

Before reaching this fourth station, the second blank 6g is wound on the waiting products, in such a way as to form the side faces of the lid 13 and to close the side flaps 78 and 79 of the second blank 6g on the products.

At this point, the products wrapped in the partially completed lid 13 are used to carry out the horizontal or vertical filling of the display tray 12 as described above.

In the passage from the fifth to the sixth station, where glue is sprayed for the display tray 12 both on the previously closed side flaps 71, 72, 73 and 74, glue is sprayed on the side flaps 78 and / or 79 of the second blank 6g and the upper central flaps 80 and 81 of the second blank 6g are closed on the side flaps 78 and 79 in such a way as to complete the formation of the lid 13.

At the same time, the lower central flaps 76 and 77 of the first blank 6f are closed, respectively, on the side flaps 71, 72 and 78 on one side and on the side flaps 73, 74 and 78 on the other side in such a way as to complete the formation of the side walls of the tray and glue it to the lid.

In the sixth station the conformation and the simultaneous squaring of the first blank 6f and the second blank 6g takes place with the crushing of the central flaps 76 and 77 and 80 and 81 for their fixing to the side flaps 71, 72, 73, 74, 78 and 79 by means of the previously interposed glue.

In the seventh station, coinciding with the exit station, the expulsion of the display tray 12 with the completed lid 13 takes place. It should be emphasized once again that the machine and the procedures described, that is the stations and the defined phases in which the cardboard formation, filling, packing and closing cycles are carried out are given by way of non-limiting example.

The number of stations and their succession can be varied depending on the speeds, intended as packages per minute processed, or on the type of product. For example, if more than one operation is carried out in a station, you can think of adding an additional station or carrying out the operation in a previous station. In this way, by decreasing the operations that are carried out in a station, the duration of the pause in the station in question decreases, decreasing the cycle times and increasing the speed of the machine.

In practice it has been found that the machine for forming and filling packaging container bodies and the processes that can be produced with it, according to the invention, fully accomplish the intended aim as they allow the main types of packaging to be formed and filled in a manner simple, automatic and effective, without modifying the machine but activating, with a simple format change, the stations necessary for the processing of a specific type of format.

The machine for forming and filling packaging container bodies and the processes thus conceived are susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.

For example, for the previously described horizontal filling steps they can be carried out by means of an advancement device, particularly for the advancement in canning machines for manufactured products, comprising at least one pusher element defining a thrust surface suitable for contacting a stack of products resting on a loading surface of a canning machine. For example, this device can comprise an appendage associated with the pusher element, projecting orthogonally with respect to the thrust surface and which can be placed in correspondence with the loading surface in such a way as to be positioned below a portion of the envelope projecting cantilevered from the loading surface and to partially lift the package by tilting it before proceeding with the advancement of the package along the loading surface.

Furthermore, all the details can be replaced by other technically equivalent elements.

For example, the closure of the American case with top loading or front loading could be obtained by replacing the glue spraying stations with taping or scratching stations.

In practice, the materials used, as well as the dimensions, may be any according to the requirements and the state of the art.
