Description

The present invention relates to a method and a device for folding a blank made of wrapping material for the production of an insert for a rigid tobacco product packaging.

More particularly, the present invention relates to a method and apparatus which can be used to fold a blank of wrapping material for the manufacture of an insert which is part of a rigid tobacco product package designed to receive a group of tobacco products of reduced dimensions; that is to say a group of tobacco products which is smaller than the total internal volume of the pack, and the following description expressly refers to this application, but without restricting the generality.

In the prior art, rigid hinged lid cigarette packs are known which are designed to contain a group of cigarettes which is smaller than the total internal volume of the pack and which includes a container having an open top and one at the Container along a hinge axis articulated lid, which is pivotable relative to the container between an open position and a closed position to close the open end. The parallelepiped-shaped container has a front wall, a rear wall, a bottom wall and two side walls, and includes an insert or a filler element which is inserted into the interior of the cigarette pack to cover the part of the cigarette left exposed by the group of cigarettes To occupy the interior volume. The filling element is obtained by folding a blank of wrapping material made of cardboard and a stop wall, two side walls which are arranged at opposite ends of the stop wall and are oriented orthogonally to the stop wall, and a top wall which is connected to an upper end of the Stop wall connected and aligned orthogonally to the stop wall, includes.

The stop wall, which is opposite and parallel to the front wall of the container and extends in the longitudinal direction up to the hinge axis of the cigarette pack, rests against the group of cigarettes, while the side walls and the top wall of the filling element with the corresponding free edges on the rear Against the wall of the container.

In a first embodiment, the filler element further includes two angled wings located at opposite ends of the top wall. The angled wings are folded into a position orthogonal to the stop wall and the top wall and bear against upper portions of the inner surfaces of the side walls of the filler element.

With reference to the 1 denotes the reference number 1 a blank of wrapping material in its entirety, which is intended for an insert or a filling element 2 ( 2 ) which is part of a tobacco product package (not shown) configured to receive a group (not shown) of tobacco products that is smaller than the total internal volume of the package. The cut 1 is (preferably) such that it can be cut off from an endless strip (not shown) of wrapping material without waste (without waste).

In the following description the parts of the blank 1 , where possible, with apostrophized reference numbers that are identical to the reference numbers (without an apostrophe) to identify the corresponding parts of the insert 2 from 2 are.

The cut 1 has a substantially rectangular shape and includes two longitudinal primary lines of weakness 3 which are parallel to each other and two transverse primary lines of weakness 4th which are parallel to each other, which form a first rectangular field 5 ' define that the rear wall 5 of use 2 forms, and a second field or wall 6 ' define the top wall 6th of use 2 forms, and a third field 7 ' define that the stop wall 7th of use 2 forms.

The first field 5 ' has a pair of wings or side walls 8th' on which the side walls 8th of use 2 form those on opposite sides of the first field 5 ' are arranged and from the first field 5 ' through the longitudinal weakening lines 3 are separated. It should be noted that the field 6 ' and the wings 8th' have the same transverse dimension or width.

The wings 8th' have corresponding tabs 9 ' on that with the appropriate wings 8th' via a transverse secondary line of weakness 10 are connected and the wings 9 of use 2 form. These tabs 9 ' form extensions of the wings 8th' on the side of the field 6 ' and are intended to be part of the top wall 6th of use 2 to build.

In an alternative embodiment (not shown) of the blank 1 assigns the field 6 ' two tabs at its opposite ends 9 ' on that with the box 6 ' via corresponding extensions of the longitudinal primary lines of weakness 3 are connected. These tabs 9 ' are intended to be part of the side walls 8th of use 2 to build.

It should be noted that in both of the above-described embodiments of the blank 1 the tabs 9 ' have a substantially square shape.

The folding of a blank 1 for the purpose of giving him the shape of the insert 2 to lend, is carried out by this first, preferably after it has been separated from the said (not shown) continuous strip of wrapping material, in the expanded state and in (preferably) horizontal orientation ( 5 ) and fed over a folding iron 11 is arranged that with a conveyor 12th is connected, the (preferably) a plurality of folding irons 11 wearing. This sponsor 12th is part of a device for folding blanks 1 from envelope material, which in the 5-8 in their entirety with the reference number 100 is marked.

The sponsor 12th can, for example, consist of a transport wheel, which can be rotated in step mode or continuously around an axis and a large number of folding irons along its circumference 11 carries, which are arranged at the same angular distance from each other. The following description refers to a conveyor consisting of a transport wheel 12th consists that in step-by-step operation around a vertical Axis is rotatable in one in the 5-8 with an arrow F direction and by the action of drive means, which are shown schematically in the form of a block A1 are shown.

The described feeding of each blank 1 on a folding iron 11 takes place in a support area D, which the transport wheel 12th worn folding iron 11 go through one after the other.

In the in 5 The work situation shown is the cut 1 above the folding iron 11 arranged with its tabs 9 ' with reference to the direction of rotation F of the wheel 12th are located downstream, and is located between and held in place by a slide 13th with a vertical line of action running along part of its upper surface and a counter slide underneath 14th , also with a vertical line of action, which is arranged adjacent to a portion of the lower surface.

The folding iron 11 has a vertical through opening 15th on, through which the slide is located 13th and 14th can move in both directions with a vertical direction of movement, as a result of the engagement of drive means of known type, which are in the 5 are shown schematically in the form of a block A. This opening 15th has a rectangular shape that is equal to the sum of the shape of the field 5 ' and the shape of an adjacent recess 16 of rectangular shape, that of the blank 1 between the wings 8th' near the field 5 ' and their dimensions approach, at least at the upper mouth of the opening 15th , with oversize the overall dimensions of the field 5 ' and the recess 16 at.

In the work situation of 5 is the field 6 ' of the cut 1 with reference to the direction of rotation F of the wheel 12th directly downstream after the opening 15th arranged.

With the folding iron 11 are, essentially at the two apexes of the opening 15th with respect to the direction of rotation F of the wheel 12th in front and directly below the flaps 9 ' of the cut 1 are arranged, the in 5 position shown assumes corresponding fixed folding elements 17th (or "mandrels") connected, which are directed upwards and their upper ends essentially on the plane of the blank 1 lie.

About the folding of the blank 1 perform will be the slider 13th and the counter slide 14th over a suitable route ( 6th ) are lowered and translate through the opening 15th of the folding iron 11 out.

During this lowering, the tabs step 9 ' of the cut 1 with the corresponding fixed folding elements 17th engage and begin to move around the appropriate transverse weakening lines 10 to rotate and thus to approach each other, while the wings also 8th' begin to become, as a result of their gradual engagement with the respective adjacent edges of the opening 15th upwards around the corresponding longitudinal weakening lines 3 to turn. The field 6 ' (and the associated field 7 ' ) thus also begins, as a result of its gradual engagement with that with respect to the direction of rotation of the wheel 12th downstream edge of the opening 15th upwards around the transverse weakening line 4th to turn over it with the field 5 ' connected is.

As soon as the slide 13th and the counter slide 14th into the opening 15th lowered by a length substantially equal to the width of the field 6 ' and the wing 8th' ( 7th ) is, are the tabs 9 ' 90 ° towards each other around the corresponding transverse weakening lines 10 folded the wings 8th' are 90 ° upwards around the corresponding longitudinal weakening lines 3 and relative to the field 5 ' rotated and the fields 6 ' and 7 ' lie coplanar to each other, rotated 90 ° upwards around the transverse weakening line 4th that the field 6 ' with the field 5 ' connects, being the field 6 ' against the tabs 9 ' is arranged lying on top.

The slider 13th will then from the opening 15th of the folding iron 11 pulled out by lifting ( 8th ) and the wheel 12th is turned on to perform a rotation step in the direction of arrow F. The consequent shift of the folding iron 11 , in which the cut considered above 1 is partially included, which is parallel to an orthogonal to the translational direction of the slide 13th and the counter slide 14th lying plane takes place, brings the field 7 ' in contact with a fixed folding element 18th that with reference to the arrow direction F downstream of the folding iron 11 and substantially tangent to the top surface of the folding iron 11 is arranged. The encroachment of the field 7 ' with the fixed folding element 18th causes the field to be rotated by 90 ° 7 ' around the transverse line of weakness 4th about it with the field 6 ' connected is ( 8th ), and the cut 1 is at this point in time fully in accordance with the in 2 Folded shape shown and can be removed from the wheel in a manner not shown 12th can be removed in order to be used for the production of a tobacco product packaging.

The cutting of 3 is in its entirety with the reference number 19th designates and retains for its constituent parts, as far as possible, those relating to on the components of the blank 1 used reference numbers.

This cut 19th differs from the cut 1 primarily by having the field 5 ' the same length as the wing 8th' has (actually is in the blank 19th the recess 16 unavailable). Further is the section of the blank 19th the one with the field 6 ' and the tabs 9 ' provided section is opposite, at the end of the field 5 ' and the wing or the walls 8th' with a box or a wall 6 " (which the lower wall 6th of an operation 20th form) as well as with two tabs 9 " equipped that, in terms of the field 5 ' and the wings 8th' , Shapes and arrangements the same as those of the field 6 ' and the tabs 9 ' are. The tabs 9 " are with corresponding wings 8th' connected via secondary lines of weakness, which in the 3 with the reference number 10 ″, and form extensions of the wings 8th' self.

For folding the blank 19th for the production of an insert or a filling element 20th as in 4th shown are each folding iron 11 four fixed folding elements 17th assigned of the type described above, each in the vicinity of one of the four peak points of the opening 15th below a corresponding tab 9 ' , 9 '' of the cut 1 that the in 5 position shown, are arranged. When the slide 13th and the counter slide 14th to carry out the folding of the blank 19th are lowered in the manner previously described, the tabs kick 9 ' and 9 '' of the cut 19th with the corresponding fixed folding elements 17th engage and rotate about the corresponding transverse lines of weakness 10 and 10 " similar to that described above, and the wings 8th' and the fields 6 ' and 6 ″ are rotated 90 ° around the corresponding longitudinal 3 and transverse 4 primary weakening lines over which they are connected to the field 5 ' connected (in the 3 the transverse weakening line of the field 6 "is marked with the reference number 4"). The wheel then performs a rotation step in the direction of arrow F, and the field 7 ' comes into contact with the fixed folding element 18th and rotates 90 ° around the transverse weakening line 4th about it with the field 6 ' connected to the folding of the blank 19th according to the in 4th Execute represented form.

The cutting of 9 is in its entirety with the reference number 21 designates and retains for its components, as far as possible, those relating to the components of the blank 1 used reference numbers.

This cut 21 differs from the cut 1 by having both wings 8th' , in corresponding, longitudinally central regions and at a predetermined distance from the transverse line of weakness 10 , from a corresponding incision 22nd are traversed, the parallel to the transverse weakening lines 4th is. Regarding each wing 8th' another incision extends 23 along the longitudinal line of weakness 3 who have favourited the wing 8th' with the field 5 ' connects over a length not less than the length of the tabs 9 ' , starting from the point of intersection between the incision 22nd and the longitudinal line of weakness 3 and in the furthest from the tab 9 ' distant direction. From the other end of each incision 23 branches a transverse secondary line of weakness 24 starting the corresponding wing 8th' parallel to the incisions 22nd passes through.

In this embodiment of the blank 21 is the incision 22nd along the wing 8th' between the transverse secondary lines of weakness 10 and 24 arranged. In an alternative embodiment (not shown) is the line of weakness 24 along the wing 8th' between the secondary transverse line of weakness 10 and the incision 22nd arranged. In both embodiments of the blank 21 is the distance between the two transverse secondary lines of weakness 10 and 24 smaller than the length of the field 7 ' , measured orthogonal to the furthest from the field 5 ' distant transverse line of weakness 4th .

In the area of each wing 8th' define the incisions 22nd and 23 and the transverse secondary line of weakness 24 a tab 25th that equal the wings 9 ' is and relative to the corresponding wing 8th' around the transverse line of weakness 24 are rotatable. It should be noted that the tabs 25th can take on a square or rectangular shape.

For folding the blank 21 for the production of an insert or a filling element 26th as in 10 shown are each folding iron 11 (in a manner not shown) four fixed folding elements 17th assigned to the type described above. Two folding elements 17th are in the above in terms of the folding of the flaps 9 ' of the cut 1 indicated position, and the other two folding elements 17th are arranged below the corresponding areas in which the tabs are located 25th located when the cut 21 when spread out over the folding iron 11 is arranged.

When the slide 13th and the counter slide 14th to carry out the folding of the blank 21 in the manner previously described through the opening 15th of the folding iron 11 are lowered through the tabs 9 ' and 25th of the cut 21 with the corresponding fixed folding elements 17th engage and rotate 90 degrees upward about the corresponding transverse secondary lines of weakness 10 , 24 similarly we did above with regard to the folding of the flaps 9 ' of the cut 1 described. The wings 8th' and the field 6 ' are also rotated 90 ° upwards around the corresponding longitudinal 3 and transverse 4 primary weakening lines over which they are connected to the field 5 ' are connected.

The wheel then performs a rotation step in the direction of arrow F, and the field 7 ' comes into contact with the fixed folding element 18th and rotates 90 ° around the transverse weakening line 4th about it with the field 6 ' connected to the folding of the blank 19th according to the in 10 Execute shown shape, and lies against the tabs 25th at.

The precaution described, the presence of the tabs 25th provide and the field 7 ' against the tabs 25th Letting it lie takes the field 7 ' any possibility of taking incorrect positions, such as introducing it between the wings 8th' due to excessive rotation (more than 90 °) of the field 7 ' along the transverse primary line of weakness 4th that the field 7 ' from the field 6 ' separates, towards the field 5 ' .

It should be noted that in order to make the stakes 2 , 20th , 26th make the tabs more robust 9 on the corresponding top (or bottom) walls 6th and side walls 8th according to the above-described embodiments of the blanks 1 , 19th , 21 can be glued on. In accordance with the above description and objects of the present invention, the above-contemplated blanks are made 1 , 19th and 21 folded to each insert 2 , 20th and 26th in an extremely simple and economical manner, since all of its components which have to be folded are handled without the use of movable folding elements, the production of which is complex and expensive.
