DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION The invention relates to a device for packing bottles flat in a carton. The example shown is not limited to the packaging of 6 bottles flat in the carton. The cardboard for this is a cardboard with internal dimensions of 488x303x77 mm.

The carton is made from a blank cut as shown in Figure 1. To make a rigid cardboard, the blank is composed of 5 papers, an outer cover kraft, a fluted paper, a median paper, a corrugated paper, an inner cover paper. One or more of these papers may be recycled papers.

The carton once produced has a bottom, two longitudinal faces, two side faces and a top.

To do this, the cut blank 1 has a rectangular back surface 10 adapted to produce the bottom of the carton adapted to receive the bottles flat.

To achieve the longitudinal faces and the top, the blank has two large flaps 11a, 11b extending outwardly of the rectangular back from long sides of the rectangular back.

The large flaps each comprise a first portion forming a longitudinal face 13a, 13b of the cardboard connected to the back by a first fold line 101 and a second portion 14a, 14b forming a half wall of the top of the carton connected to the first part by a second fold line 102. The longitudinal faces and the top are made by two folding steps, the first raising the large flaps by folding the blank at the first fold lines 101 to achieve the longitudinal faces, the second folding the second portions 14a, 14b of the large flaps around the second fold line 102 to form the top of the carton.

To form the side faces of the carton, the blank has two small flaps 12a, 12b extending outwardly from short sides of the rectangular back.

The small flaps 12a, 12b having a first wall element 15a, 15b connected to the back by a third fold line 103, and a second wall element 15'a, 15'b connected by a fourth fold line 104 to the first wall element.

According to an important aspect of the invention, the fourth fold line folds the small flap to make the side faces of the cardboard double walls. The double walls of the side faces of the cardboard are obtained by folding the second wall element 15'a, 15'b on the first wall element 15a, 15b.

To stiffen the cardboard and the large flaps comprise tabs 16a, 16'a, 16b, 16'b extending the first portion of the large flaps forming the longitudinal sides of the cardboard. These tabs bend at 90 ° of the longitudinal faces and are housed between the double walls 15a, 15b, 15'a, 15'b of the side faces of the carton which increases the thickness of these faces.

The tabs 16a, 16a ', 16b, 16b' comprise according to the example tabs 17a, 17'a, 17b, 17'b extending perpendicular to the tabs in a direction in extension of the first wall elements of the small flaps. These tongues are adapted to fold between the double walls 15a, 15b of the side faces of the carton which adds further thickness to the short sides.

The fourth fold line 104 between the wall elements of the small flaps comprises two grooving threads 18, 18 'parallel to the short side of the rectangular back. These two grooving threads are parallel and spaced so that when folding small flaps a space receiving tabs and tabs is provided between the wall members 15a, 15'a and 15b, 15'b. These two grooving threads make it possible to make a double fold and to form between the folds a bearing edge of the external edges of the half walls at the free edge of the double walls.

The first grooving net 18 close to the back has a marking height greater than that of the second grooving net 18 'so that its folding takes place in priority. The bearing edge made by stacking the wall elements, tabs and tabs. It is a quadruple width of the thickness of the blank given by the sum of the thickness of the double wall, a tab and a tongue which makes for a blank of 2.3 mm a border width of support of about 9 mm given the thickness of the folds.

For glass bottles requiring additional protection and a separation of the bottles, an insert as shown in FIG. 6 is made from a cut blank 2 comprising a protective strip 2c provided with a first edge 2a and a second longitudinal edge 2b. The interlayer comprises a succession of foldable flaps 3, here 5 flaps intended to be positioned between the 6 bottles received in the carton.

The flaps extend in a general direction perpendicular to the length of the protective strip 2c and are connected to the first edge 2a by feet 4 having fold lines 5, 6. A first fold line 5 is made between the strip protection and the foot along a first line parallel to the first edge 2a. The second fold line made between the foot 4 and the flap 3 is perpendicular to said edge.

The flaps first fold at 90 ° to the feet 4 along the second fold line 6 and then the foot is folded by a fold along the first fold line 5 so that the flaps are positioned under the protective strip according to planes perpendicular to the plane of the protective strip.

To maintain the position of the shutters before insertion between the bottles, the protective strip on the bottles, the folding flaps are provided with lugs 8 for fastening the flaps on the second edge 2b of the protective strip after positioning flaps under the protection strip 2c.

The protective strip is of sufficient length and width to cover a central portion of the bottles perpendicular to said bottles and serves to protect the labels of these bottles when cutting an adhesive tape closing the top to proceed with the opening of the carton .

The direction of the flutes 202 is perpendicular to the elongation of the strip to increase the tear strength of the protective strip when cutting the adhesive tape. The invention further relates to a bottle-packing machine comprising a casing frame, a non-limiting example of which is generally shown in FIG. 4.

The frame comprises a table 31 for receiving and forming the cardboard provided with sequential forming means made by means of forming guides 32a, 32b, 32'a, 32'b, 34a, 34'a, 34b, 34'b, only the guides 32a, 32b and 34a, 34'a, 34b, 34'b being shown in Figure 4 for better visibility of the frame. These forming guides are adapted to form the longitudinal sides of the carton by a depression of the blank 1 in the frame.

First forming guide means 32a, 32b, 32'a, 32'b receive the flat cardboard as shown in Figure 2A on planar terminations. They comprise ramps and vertical sections that go during the depression of the carton in the frame raise the tabs 16 as shown in Figures 2B and 2C.

To form the longitudinal faces of the carton, the frame comprises the second guides 34a, 34'a, 34b, 34'b, realizing ramps of rounded shape whose gradual inclination achieves a flared opening for receiving the large flaps of the blank then the strongly inclined walls closing the large flaps. The guides, arranged under the long sides in Figure 2A will fold the longitudinal sides of the cardboard during the depression of the cardboard in the frame as shown in Figures 2C and 2D because of their spacing being gradually reduced laterally in their lower part.

Round cylindrical cylindrical rollers 39 are mounted on the frame on either side of the guides. These rollers, less laterally spaced apart that the guides 34 complete the folding of the longitudinal faces at the end of insertion of the carton into the frame. These rollers mounted for rotation about vertical axes also make it possible to guide the cardboard laterally when it is removed from the frame by sliding it on the table without the guides 34a, 34'a, 34b, 34'b having a rounded shape. do not rub against the longitudinal sides of the cardboard.

Returning to FIG. 4, the frame comprises movable means 33a, 33b for forming the lateral and folding faces of the second elements 15'a, 15'b small flaps towards the inside of the carton to form the double walls of the faces. side of the carton.

To do this, according to Figure 5A the movable means 33a, 33b are in an inclined positon C for receiving the cardboard and pre-folding the side walls of the cardboard where the jaws part angularly.

The lower pushing elements 37 bear against the first wall elements 15a, 15b of the small flaps and the second upper pushing elements 36 bear against the second wall elements 15'a, 15'b of the small flaps and incline them by compared to the bottom of the cardboard.

According to Figure 5B. the moving means are returned by a jack 42 in a position for which the upper and lower pusher elements are aligned vertically in a position A folding the lateral faces of the carton at 90 ° to the bottom.

According to Figure 5C. a rotation of the jaws 35 movable relative to the moving means to the position A 'actuates the second upper pusher elements 36 to fold the second wall elements 15'a, 15'b small flaps on the first wall elements and form the double wall. To do this, the free edge of the double wall being formed fits into the lumen 38 as shown in Figure 6. The movable jaws are actuated by jacks 40 on plates 43, 44 fixed to the frame 30 and carrying the fixed jaws 35b.

Pusher elements 36, 37 consist of rollers rotatably mounted on shafts 47 disposed on either side of the lumen 38 and parallel to the lateral faces of the carton. These rotatably mounted rollers can roll on the carton during forming of the side faces and can be flexible to not mark the carton.

According to FIG. 5D, the mobile forming means 33a is lowered into a retracted position B adapted to disengage the cardboard by translation on the table 31. To do this, the mobile means 33a is mounted on a plate 45 slidably mounted relative to the plate. 43 on a first cylinder 40 adapted to move it between a forming position of a side face of the carton and the retracted position C.

The process for producing the carton and for packaging the bottles comprises a step of laying the carton 1 flat on the frame 30 as in FIG. 2A, and a step of driving the carton into the frame so as to preform the longitudinal faces of the carton. carton according to Figures 2B, 2C, 2D, a folding step of the small flaps to form the double walls according to Figure 5C, a step of placing the bottles 50 in the carton and a step of translating the carton on the table to close the large flaps by means for example ramps 60 according to Figure 5D. The step of translating the carton comprises a step of sticking an adhesive tape on the large flaps of the top of the carton by a bonding machine 61.

FIG. 5E represents a variant of the mobile forming means for which the movable jaws 135 are connected to the jacks 141a, 141b by a linkage system 150, 151 which allows said movable jaws to tilt backwards in a position C 'similar to the standby C position of the blank.

In this configuration, the mobile means 133a, 133b no longer need to tilt which saves a cylinder and two joints of the moving means on the table.

In this variant, the jaws 135 carrying the upper pusher elements are movable in inclination between the inclined positron C 'rear pre-folding of the side walls of the carton and the inclined front position A folding the lateral faces of the carton. The movable jaws 135 are in this case capable of rotation about their bearing axis of about -30 ° to -40 ° in the backward direction to about + 170 ° to + 180 ° in the forward direction cardboard side.

The movable means 133a just as the movable means 33a is able to fade under the table under the action of the jack 140 moving the support 145 carrying the jaws relative to the support 143 fixed to the table 31. The driving step cardboard comprises successively: a folding of the tabs 16a, 16'a, 16b, 16'b of the large flaps in a direction perpendicular to the plane of the large flaps FIG. 2B; a folding of the large flaps along the first fold line 101 to form the longitudinal sides of the carton and to bring the tabs 16a, 16'a, 16b, 16'b along the third fold line 103 of the small flaps FIG. 2c, 2D; - Folding the small flaps along the third fold line 103 Figure 5A. The folding step of the small flaps is continued according to FIGS. 5B, 5C by an automatic folding under the sequential action of the jacks 42, 41a, 41b. The jack 42 straightens the moving means 33a, 33b and the cylinders 41a, 41b fold the small flaps 180 ° around the fourth fold line 104.

This last folding begins with the first grooving thread 18, a folding of the tongues 17a, 17'a, 17b, 17'b folded by said folding, continues with the second grooving net 18 '.

The double fold is represented in FIG. 6, the wall elements of the small flaps surrounding the tabs 16a, 16'a, 16b, 16'b and the tongues 17a, 17'a, 17b, 17'b which produces the border of support of the outer edges of the half walls at the free edge of the double walls.

The movable jaws are then returned to the position of Figure 5B to allow to put the bottles in place, cardboard pressed into the frame.

The method then optionally comprises a step of laying the interlayer, flaps 3 arranged between the bottles in the carton, the protective strip 2c being positioned under a line joining the half-walls 14a, 14b of the top of the carton so as to constitute a protective strip of the bottles.

Then, as seen above, the carton is taken out of the frame longitudinally to a sticking station of a self-adhesive film as shown in FIG. 5D.

In the context of the invention, it should be noted that the corrugated cardboard has its grooves 201 oriented parallel to the lateral faces of the carton which makes the free edges of the longitudinal faces more rigid and makes it easier to fold the small flaps which remain rigid due to the presence of the double wall and legs whose flutes will be vertical.

The folding part of the double walls can be automated by sequencing the control of the cylinders 40, 41, 42 to automatically place the mobile means 33a, 33b in the vertical position and then rotate the movable jaws 35a to fold the small flaps with the upper pushers 36, the return of the upper pushers in vertical alignment with the lower pushers and the erasure of the moving means 33b for removing the cardboard from the frame.

To move the carton the table 31 may comprise endless belts 46, 48 shown in Figure 4 or a roller conveyor. The invention is not limited to the example shown and in particular can be applied to cartons of sizes adapted to receive more or fewer than six bottles.
