CASE CROSS-EXISTING METHODS FOR SIX OR TWELVE

  BOTTLES, MACHINES AND CROSSLINKS IMPLEMENTING THEM

  The present invention relates to several internal crossover methods of corrugated cardboard boxes or the like mounted glued bottom for the casing of six or twelve bottles. The invention also relates to machines implementing said methods as well as

  braces particularly suitable for such machines.

  The transport of bottles and in particular of bottles of wine is very widely carried out today in lots of six or twelve bottles which must therefore be packaged very correctly in boxes generally made of corrugated cardboard or the like comprising two rows of three bottles for boxes of six and three rows of four bottles for boxes of twelve. The bottles are placed in these cases by means of case packers which

  most of the time must operate at high speed.

  On the other hand, the bottles which are placed in each case in both directions, generally bottom down and neck up, must be chocked to avoid contact between two successive bottles in one direction or the

perpendicular direction.

  According to the most widely used method, there are between two rows of bottles sides of cardboard extending respectively over the width and over the length of the box, so as to constitute inside a crossed rack determining as many identical housings. than bottles to cash; of course, the height of the blades can be variable, but always between a maximum value corresponding to the height of the box outside the upper flaps and a minimum height corresponding to the setting of the bottle bodies, thereby protecting the labels against friction caused by transport. This minimum height will be called hereinafter: "height

protected "from the bottle.

  It is well known that corrugated cardboard boxes, for example the American boxes capable of receiving six or twelve bottles, are mounted on formers and before being filled at the packing station, racks six or twelve bottles are arranged inside the same 5 boxes. This intermediate crossover operation is therefore very important because it must be carried out at the rates required by the bottling line. This result is difficult to achieve except by using very bulky equipment, which ultimately amounts to limiting the rates on the same boxing area. Among the usual cross-cutters, cross-cutters are known which are arranged transversely with respect to the line for conveying the boxes leaving the forming machine up to the case packer; such cross-inserts insert cardboard strips inside the boxes, in order to constitute the desired cross-over. For this, the boxes are presented under the insertion head of the crosshead so that their advance on the conveyor is in the direction of their greatest length in order to obtain maximum stability in their transport; on the other hand, we can clearly see that the insertion of the vertical blades to form the spider on this type of boxes requires storage magazines necessarily on one side and the other of the conveyor line, which generally requires two drivers for the crossheader. To overcome all these drawbacks, it is here proposed to take the boxes out of the forming machine according to their smallest dimension, ensuring their stability by accumulating them against each other on the conveyor. In this regard and in accordance with the invention, the internal cross-stitching process of corrugated or similar cardboard boxes determining identical or unequal housings intended to collect six or twelve bottles, mounted on a forming machine and then transferred to the output by a linear conveyor in position standing and open on top, first towards a cross-grader, then towards a case packer is remarkable in that said cross-strut extends in a bridge longitudinally above - 3 - and in the axis of the conveyor and in that the face front of the boxes which is perpendicular to the direction of advancement of the conveyor, coincides with the side of said boxes, the size of which corresponds to three bottles placed side by side in the same direction or upside down. The fact that the most widely used crossovers are arranged transversely to the conveyor, causes very harmful dimensions between parallel casing lines and a reduction in technical aisles, due to the fact that the various components of the lockers cannot be supplied with a only side, that of the cases; these drawbacks are overcome by the longitudinal position of the crosshead over the conveyor; in addition, the process according to the invention provides the decisive advantage of an increase of more than thirty percent in assembly / packing rates in the six-bottle configuration, resulting from the very position of the boxes which, in the process, move forward on the conveyor according to their width, whereas conventionally the same boxes are placed along their longitudinal axis in the axis of the conveyor to avoid their tilting in the operation; according to the process, the boxes at the exit of the forming machine arrive on the conveyor one against the other and pass

  tight, providing self-maintenance on the conveyor.

  Several variants of the cross-fitting method according to the invention will now be described, implemented by machines using specially lockers.

  - Figure 13 is a view similar to Figure 12 but relating to a fourth variant of the process in accordance

to the invention.

  With reference to FIG. 1, the cross-linkers 1 of the prior art are conventionally arranged transversely relative to the axis of the conveyor 2 carrying the boxes 3 previously formed on a box-forming machine (not shown). By way of example, the box 3 for six bottles is placed on the conveyor 2 at the exit from the forming machine and upstream from the crosspiece 1, so that its longitudinal axis coincides with the direction of advancement of the conveyor 2. The box 3 then arrives at point 4 under the insertion member of the crosspiece 1 o join a double element 5 extracted from a specific magazine and central blades 6 extracted from a magazine located opposite the crosspiece to form gradually a rack 7 which will then be inserted into the box 3 still waiting at point 4, then moved thus equipped by the conveyor 2 to the case packer (not shown in the figure). As can easily be seen in FIG. 1, the stores of double elements 5 and of blades 6 are located on either side of the line for conveying the boxes 3, requiring surveillance of the crosspiece 1 by at least two people ; on the other hand, it can be seen that the crosspiece 1, located transversely with respect to the casing lines, comes to hamper the aisles between

  several parallel lines of case packer.

  In accordance with FIG. 2 and according to the invention, the case packer 1 is pivoted by 900 in order to arrange it in a longitudinal bridge along the axis of the conveyor 2. Naturally, the boxes assembled 3 at the outlet of the forming machine (not shown) on the left of Figure 2 arrive on the conveyor 2 front face perpendicular to the direction of advance, corresponding to the length of the box, that is to say 90 relative to the diagram of Figure 1 showing the prior art; this arrangement, which is less favorable for the stability of the boxes 3 on the conveyor 2, however compensated by an accumulation of the boxes against each other thus ensuring their self-maintenance, provides numerous advantages: increase in the number of boxes treated since they are present by their width, appreciable reduction in overall dimensions in the longitudinal and transverse direction of the line, supply of all the stores on one and the same side of the conveyor which will advantageously be the same as the supply of the sides for mounting the boxes on the upstream forming machine, finally saving of personnel insofar as the box forming machine and the cross brace can be handled by a single driver. Referring to Figures 3, there will now be described the formation and casing of a rack 7 for six bottles already used in the prior art, in particular on the crosspiece of Figure 1, for example a

  crossover from the Swiss manufacturer RODA.

  The rack 7, indifferently called a cross, is obtained by the combination of a blade 10, called the central blade, with a double element 11 stored flat in a magazine of the cross brace as shown in top view in FIG. 3b; the double element 11 comprises two identical wings 12 and 12 ′ made of corrugated cardboard and hinged head to tail to a normally rectangular flat bottom 13 by virtue of two fold lines 14, 14 ′, parallel to each other and distant from one another another one worth a diameter of bottles. In the transverse median axis of the double element 11, provision is made

  a cut 15.15 'respectively on the wings 12.12'.

  Each cut 15, 15 ′ from the fold line 14,14 ′ of the corresponding wing extends in the median axis of -7- each wing over a height sufficient for the folding of each wing 12,12 ' according to the arrows P and Q of FIGS. 3d and 3e, the central blade 10 comes to fit there precisely until the uncut upper parts come into abutment on shoulders 16, 16 'provided for this purpose on the upper part of the central blade 10, as shown in Figure 3e. It will be noted, in this regard, that the lower part of the two cutouts 15,15 'coinciding with the fold lines 14,14' has a width corresponding to the thickness of the central strip 10 allowing the latter to be simply adjusted such that shown in Figure 3e; on the other hand, in their upper part, the two notches 15, 15 ′ form a sharp angle providing a tightening of the blade 10 when it is completely embedded in the double element 11, as shown in FIG. 3e, after folding into a U of the same double element shown in perspective in Figure 3c Note that the wings 12,12 'have a maximum height equal to the height of the boxes as shown in Figure 3f; the width of the wings 12,12 'at their upper end is equal to approximately twice the diameter of the bottles as shown in Figure 3g; cut sides are advantageously provided on the lower part of the same wings up to their connection line with the bottom 13 to reduce the consumption of cardboard and the weight of the spider; however, the length of the bottom 13, that is to say the length of the fold lines 14, 14 ′ is sufficient to ensure the rigidity of

the double element 11.

  The mounting of the rack 7 as shown in perspective in Figure 3c, is obtained by the cooperation of three movements as shown in the arrows P, Q, V of Figures 3a, 3c, 3_ and 3e. The blade 10 extracted from a storage magazine is brought by means known from the RODA cross-cutter to the right of the double element 11, itself extracted flat from another magazine, so that the vertical plane of the blade 10 coincides with the transverse median plane of the double element 11 (FIG. 3a). The blade 10 is then lowered vertically along V downwards to come gradually to bear on the bottom 13 of the element 11, lateral rollers contributing to raise along wings P and Q (FIG. 3d) the wings 12, 12 'of the element 11 around the fold lines 14,14 'which gradually surround the blade 10 having cut sides 17 at all its angles in order to facilitate the rotational movement of said wings which then come into abutment on cutouts 16,16' in position parallel vertical, as shown in Figure 3e; the following downward movement V brings the assembly assembled up to the box 3 positioned on the conveyor 2 directly above the insertion head of the crossheader, so that the rack 7 comes exactly inside of the body 3, as shown for

above in Figure 3g.

  Referring to Figures 4 to 7, there will now be described a first method implementing the invention particularly intended for crossing a case for twelve bottles; such a method is remarkable in that, at a first station 20 (FIG. 6), a blade 21 (FIG. 4) is inserted into the box 3 parallel or substantially parallel to the front face 23 which is perpendicular to the direction of advance of the conveyor 2, said blade 21 being inserted between two support zones 22,22 ′ facing each other on the two lateral faces 23,23 ′ of the body 3 to separate the latter into two substantially equal volumes 24,25; then the box 3 is advanced on the conveyor 2 to a second station 26 where a first rack 7 of six bottles is formed and inserted, as described above with reference to FIGS. 3, pushing vertically and downwards, the central blade 10 which then drives the double element 11 which is folded around the blade 10 in the form of a U-shaped gutter, and is inserted in line with the first volume 25 of the body 3 along a plane parallel to the front face 23 located midway between the first blade 21 and the front face 23 of the body; - 9 - then shifted forward by the conveyor 2 the box 3 to bring the second volume 24 to the right of said second station 26 and in the same way insert a second identical rack 7 of six bottles formed and inserted as le5 first; finally, the box 3 is thus cleared intersected towards the case packer freeing the posts 20.26 for a new insertion of blade 21 on the one hand, of racks 7 successively in the volumes 24.25 on the other hand and this, according to a cycle which can be continuous. 10 According to a particular mode of the process which has just been described and with reference to FIG. 5, the central blade 21 is arranged to pivot between its bearing zones 22, 22 ′ on the two lateral faces of box 3; in this regard, the blade 21, normally rectangular, the height and width of which correspond to the height and width of the body 3, is cut according to the drawings in FIG. 4, showing that the width of the blade is not equal to that of the body that between the two support points 22, 22 ′ sue the lateral faces around which the blade 21 can pivot; in a particular embodiment, the blade 21 is introduced at the first station 20 in a slightly inclined fashion from top to bottom and from back to front, to provide a flared entry to the first volume 25 of the body 3 (FIG. 5), in order to facilitate the introduction of the first rack 7 which straightens the blade 21 in passing by rotation on its supports 22, 22 ', in order to clear the entry of the second

  volume 24 and allow the insertion of the second compartment 7.

  In FIG. 7, one can clearly see one of the advantages of such a method since a single and same operator 27 can drive both the box former 28 and the crosspiece 1, taking into account their proximity and their

  relative provision, as already stated.

  With reference to FIGS. 8, 9 and 10, there will now be described a second variant of the method implementing the invention for the normally regular bridging of a twelve-bottle case. This process is characterized in that one forms and inserts into the box 3, at a first station 30, a double element 31 of

- 10 -

  twelve bottle spider which will be described later with reference to FIG. 8, and which, once mounted, has the general shape of a U-shaped gutter whose width of the wings 32.32 ′ is equal to four times the diameter of a bottle and the distance between them is equal to a diameter and the height is equal to at least the protected height of the bottles and at most to the height outside the flap of the box 3; in the transverse median plane of the double element 31, there is inserted vertically, in a plane perpendicular to the direction of advance of the conveyor 2, a central blade 33 which, in its movement brings and maintains the wings 32, 32 'in vertical position and parallel and pushes down the assembly thus formed inside the open box 3 and positioned directly above the insertion head of the crossheader on the conveyor 2, without necessarily going to the bottom of the box; then the same box is thus advanced, pre-intersected in two identical volumes on either side of the blade 33, to a second station 34 o is inserted vertically in a plane perpendicular to the direction of advance of the conveyor 2, successively a second blade 35, then a third blade 36, advantageously identical, straddling the double element 31, coming once again to divide into two equal parts each of the two volumes of the pre-criss-crossed box, thus providing twelve distinct and equal housings at

the interior of said box 3.

  With reference to FIGS. 11 and 12, a third variant of the method will now be described implementing the invention for the normally regular crossing of a case 3 twelve bottles. This method differs from the previous ones in that, subject to using a double element 50 for the formation of the brace 50 as shown in FIG. 11 and which will be described below, the brace only comprises one insertion station to form and insert twelve bottle braces inside the crates. In this regard and with reference to Figure 12 and more particularly to

- 11 -

  schematic representations A, B, C of said method above the cross-bracing machine, this method is remarkable in that the body 3 being positioned directly above the vertical insertion head 51 of the cross-bracing machine, we first form a twelve bottles crosspiece from a double element 50, stored flat and then extracted from a first magazine 52, having, when mounted, the general shape of a U-shaped gutter of the same type as in the previous variants and comprising two vertical wings 53,53 ′ which are advantageously identical and articulated head to tail to a flat bottom 54 along two fold lines 55.55 ′ normally separated by a diameter of the bottle, of width normally equal to four times the diameter of a bottle and of height at least equal to the protected height of the bottles and at most equal to the height of the boxes without flap, across which in accordance with diagram A of Figure 12, along a plane perpendicular to the plane of its wings 53.53 '- that is to say perpendicularly

  in the direction of travel of the conveyor 2 (arrow AV figure 12) -

  normally passing a quarter of the width of said wings 53, 53 ′ from their leading edges 59.59 ′ in the direction of advance AV of the bodies 3, that is to say from their vertical lateral edges close to the front panel of the boxes, a first blade 33 is pushed back, of the same type as that shown in FIG. 9 and used in the previous variants, coming from a second magazine 56, which comes to bear on the bottom 54 to fold according to their two fold lines 55.55 'said wings 53.53' and maintain them in a vertical and parallel position, while driving down the assembly thus formed inside the body 3 open upwards and waiting on the conveyor 2, without necessarily going all the way to the bottom, then the box 3 thus precrossed is advanced over a distance normally equal to a diameter of bottle to reposition said box 3 under the same insertion head 51 of the crossheader in such a way that one can insert vertically and parallel to the first blade 33, a second blade 35

- 12 -

  advantageously identical to the first, straddling the U-shaped gutter in the median plane of the spider 57 in formation, (as shown schematically in B in Figure 12), then after a new advance of the box 3 on the conveyor 2 of a length normally equal to a diameter of the bottle, a third blade 36 is inserted vertically and parallel to the other two blades 33,35, in accordance with the representation C in FIG. 12; this third blade 36 which is advantageously identical to the preceding ones shares the remaining volume of the body 3, in two normally equal parts, ultimately providing twelve separate housings and

  normally equal inside said box 3.

  With reference to FIG. 13, a fourth variant of the process will be described which implements the invention for the normally regular cross-referencing of a case 3 twelve bottles. As in the previous variant, the crosspiece has only one insertion station 51 to form the crosspieces and insert them inside the boxes. In this regard and in accordance with the diagrammatic representations A, B, C of FIG. 13 arranged above the crosspiece, a first crosspiece 7 for six bottles is first formed, exactly in the same way as in the first variant of the process shown in Figures 3a to 3g, from a double element 11 stored flat then extracted from a first store 52, having when mounted, the general shape of a U-shaped gutter and having two vertical wings 12 , 12 'advantageously identical and hinged head to tail to a flat bottom 13 by two fold lines 14,14' normally distant from a diameter of bottle, of width normally equal to twice the diameter of a bottle and of height at less equal to the protected height of the bottles and at most equal to the height of the boxes without flap, across which in accordance with diagram A of figure 13 and according to a plan

  median perpendicular to the plane of its wings 12,12 ', that is

  i.e. perpendicular to the direction of travel of the

- 13 -

  conveyor 2 along arrow AV, a first blade 10 is pushed back as shown in FIG. 3, or of the same type as the blade 33 shown in FIG. 9 and used in the previous variants as a planar separator, coming from a second magazine 56 which bears on the bottom 13 of the element 11 to fold the wings 12, 12 'along their fold lines 14,14' the wings 12,12 'and keep them in a vertical and parallel position, while driving downwards without necessarily going to the bottom, the assembly thus formed inside the box 3 open upwards and waiting on the conveyor 2 in position such that this first spider 7 occupies the first half of the internal volume of the box 3 on the side of the front panel of said box, then the box 3 is half-crossed over a distance normally equal to a diameter of the bottle in order to reposition it under the insertion head 51 and insert vertically and parallel to the first blade 10 a second blade 10 advantageously identical to the first in the median plane of the body 3 as shown diagrammatically at B in FIG. 13; then the box 3 is advanced on the conveyor 2 of a length normally equal to a diameter of the bottle and finally, vertically and in the same direction as the first cross 7 is inserted a second cross 7 identical to the first in accordance with the representation C on the Figure 13, which ultimately provides twelve separate and normally equal housings inside the box 3 which is then evacuated on the conveyor 2 to make room for

  cross of the next box.

  For the sake of rationalization and insofar as the cross-bar which has just been described can be used for the implementation of the previous variant of the process, the blades 33, 35 or

  36 of the third variant in place of the blades 10.

  It goes without saying that the first, second and third blades 33, 35, 36 used in the corresponding variants are advantageously the same and they will be detailed.

- 14 -

  further on with reference to FIG. 9; on the other hand and according to a possible execution of the process, the insertion of the blades 10,33,35,36 cooperating with one or the other of the double elements 11,31,50 respectively of compartments 7,37,57 can only be partial inside a box, without however exceeding the open flap height of the same box; the total introduction is then advantageously obtained by the heads of the case packer which pushes them down at the same time as the crosspiece (s) are driven to the bottom of the box 3 by the effect of gravity of the bottles deposited on the bottom of the

items 11.31.50.

  With reference to FIGS. 8 and 9, a cross will now be described for twelve bottles of corrugated cardboard or the like which can be used particularly with the second.

  variant of the process which has been described above.

  The spider 31, made of corrugated cardboard or the like to make a rack of twelve bottles according to the second variant of the process results, as we have seen, from the folding of the double element 31 stored flat (FIG. 8) in the general shape of a gutter in U comprising two wings 32.32 'normally identical in width, at least at the top, equal to four times the diameter of the bottles, articulated on either side of a flat bottom around two parallel fold lines 38.38' distant with a length at most equal to the diameter of the bottles and at least equal to a diameter of its neck, cooperating with three separating blades 33,35,36 of a maximum height equal to that of the box 3 excluding flaps and width maximum equal to three times the diameter of the bottles, placed vertically across the double element 31 folded in a U, perpendicular to the fold lines 38,38 'of which a first central blade 33 is in the transverse median plane of element 31 and the other two come from either side of the first, at a distance equal to a diameter of the bottle; this spider is characterized in that at least the central blade 33 cooperates with two elongated cutouts 39, 39 ′, facing each other on

- 15 -

  each wing 32, 32 ′ in the transverse median plane of the double element 31; these two cutouts 39, 39 ′ come from each fold line 38, 38 ′ to extend over a sufficient height so that when the double element 31 is folded, the central blade 33 precisely fits there and provides by adequate shoulders 40, symmetrical lateral stops when the wings 32, 32 ′ are vertical and parallel to one another; this cross is still remarkable in that the other two blades 35.36 at least 10 have two vertical cutouts 41,41 'symmetrical with respect to the vertical axis of the blades and open at the bottom 42 to determine between them (Figure 9) a cross section 43, of width equal to

  a diameter of bottles, of height equal to half

  height of the wings 32.32 ′ of the double element 31 which comprises four cutouts, corresponding open upwards and extending downwards at half height, to engage in pairs with each blade 35.36 inserted vertically by the top on the double element 31 folded in

U around the central blade 33.

  With reference to FIG. 11, the spider 57 made of corrugated cardboard or the like for making a rack of twelve bottles according to the third variant of the method, results, as we have seen, from the folding of a double element 50 stored flat, in the general shape of a U-shaped gutter comprising two normally identical wings 53, 53 ′, of width at least at the top equal to four times the diameter of the articulated bottles on either side of a flat bottom 54 around two fold lines 55.55 'distant with a length normally equal to a diameter of the bottle cooperating with three separating blades 33.35.36 having a height at most equal to that of the body 3 without flaps and of maximum width equal to three times the diameter of a bottle, placed vertically across the double element 50 folded in a U, perpendicular to the fold lines 55.55 ′ of which a first blade 33 is, as we have seen, arranged in the transverse plane of the element nt 50 at a distance from the leading edge 59.59 'from the cross in the

- 16 -

  direction of advance AV of the body 3 normally equal to a bottle diameter; this spider is characterized in that this blade 33 cooperates with two elongated cutouts 58.58 ′ analogous to the cutouts 39.39 ′ in the previous variants, facing each other respectively on each wing 53.53 ′ of the double element 50 at a distance from a side edge 59.59 ′ of the double element 50 normally equal to the diameter of a bottle. These two cutouts 58.58 ′ come from each fold line 55.55 ′ to extend over a sufficient height so that when the double element 50 is folded, the central blade 33 precisely fits there and provides by suitable shoulders 40 (Figure 9) symmetrical side stops when the wings 53,53 'are vertical and parallel to each other; this spider 57 is still remarkable in that it uses, as in the previous variants, the characteristics of the blades 33, 35, 36 providing the same advantages such as

  already detailed about the crosspiece 37 for example.

  According to a particularly advantageous embodiment, the slender cuts 39, 39, 58, 58 'of the elements 31, 50 have, from bottom to top, a variable width initially equal to the thickness of the blade 33 at the level of the line of corresponding folding 38.38 ′, 55.55 ′ which then widen up to the maximum situated at about a third of the height and finally regularly shrink to 0 at a height corresponding to the shoulder 40 of the blade 33 ; in this way, at the moment when the blade 33 comes to be embedded in the cutouts 39.39 ', 58.58' of the double element 31.50 for example in the same way as for the forming of the rack of six bottles described in with reference to FIGS. 3, the wings 32, 32 ′, 53.53 ′ of the element 31.50 are counter-clamped over the thickness of the blade 33 in the abutment zone of the shoulder 40 of the blade 33, which holds the two together; in addition, to facilitate the vertical insertion of the blade 33 between the two wings 32,32 ', 53,53' of the double element 31,50 it is advantageous to soften all the lateral angles of the same blade, so to give them a rounded profile, avoiding all

- 17 -

  hanging at the time of the embedding operation. A

  preferred shape of the blade 33 is given in FIG. 9.

  It goes without saying that the blade 33 and the two other separating blades 35, 36 can be strictly identical for mounting the same rack, thereby saving on tool change and above all on storage.

of the same blades.

  It is advantageously provided that the direction of the corrugations of the corrugated cardboard used for the production of these twelve-bottle racks, will be from top to bottom for all the blades 33, 35, 36 and in the directions of the lines of

  folding 38.38 ', 55.55' for the double U-shaped element 31 or 50.

  With reference to FIGS. 6, 7, 10 and 12, there will now be described executions of machines making it possible to form and collect racks six or twelve bottles either in the boxes mounted open upwards and running linearly on a conveyor 2; these machines will be described according to whether they implement one or other of the variants of the methods which have been

detailed above.

  These crossheads include all the known means of the Swiss crossheaders RODA (not shown in detail in the figures) for the vertical insertion downwards of planar dividers 21, 33,35,36 stored in a first store 44,56 (figures 6, 10 and 12), second folding means 45 also known from RODA machines of a double element of compartments 11, 31, 50 extracted from a second magazine 46, 52 comprising two identical wings 12, 12 ', 32, 32' , 53.53 'articulated to a flat and horizontal bottom by two fold lines 14.14', 38.38 ', 55.55' parallel, coupled to third means also known (not shown in the figures) of insertion vertical downwards of said element cooperating with a central blade 10.33 extracted from a third magazine 47 in the second variant to form a pre-cross sampling, a linear conveyor 2 loading empty formed boxes 3 open on the top and various known means which do not are not shown s on

  the figures, for monitoring the progress and

  positioning of the boxes on the same conveyor 2.

  In accordance with Figures 6 and 7, the crosspiece 1 implementing the first variant of the method is remarkable in that all the means are supported by two parallel gantries 20,26 which span the conveyor 2, one 30 disposed at the entrance of the crosspiece 1 (that is to say on the left of FIG. 6) to insert the central blade 21 extracted from the magazine 44 into a box 3 positioned directly above the gantry 20 to form two identical internal volumes 24.25 by means of first vertical or slightly inclined insertion means from bottom to top and from front to back in the direction of advancement of the conveyor 2 and the other gantry 26 disposed at the outlet of the cross-cutter, for successively forming and inserting racks six bottles extracted from a second magazine 46 of blades and from a third magazine 47 of double elements 11 to be folded, first in the first volume 25, then in the second volume 24 of the case 3 successively positio born in line with the third means thanks to a controlled increment of the

conveyor 2.

  Likewise and with reference now to FIG. 10, the crosspiece implementing the second variant of the method detailed above, is remarkable in that all of the insertion means are also supported by two parallel gantries 30, 34 to the like the previous cross-over; these gantries also straddle the conveyor 2, the first gantry 30 disposed at the entrance (to the right of FIG. 10) of the crosshead supports the known means to form the double U-shaped element 31 extracted from a magazine 46 and insert a central blade 33 extracted from another magazine 47 in the transverse median plane of the element 31 by second known means, to introduce it vertically into a box 3 positioned directly above said means and the other gantry 34 at the outlet (on the left of FIG. 10) supports the known means for successively inserting two separating blades 35,36

- 19 -

  extracted from a last magazine 44, advantageously identical to the blade 33 and arranged on either side thereof in the box 3 successively positioned vertically above the first means, by a controlled increment of the conveyor 2. It will As a result, the machines which have just been described, implementing the cross-fitting method according to the invention, are also capable of forming and inserting six-bottle racks into six-bottle cases; it is enough, for the first machine, not to use the entry gantry since there is no longer a central blade and to insert, in each case presented, a rack of six bottles as has been said; with regard to the second machine, it is understandable that an adjustment is necessary to change the format of the double element requiring a certain number of simple adjustments of the stops relating to the insertion means; naturally, portal 34 is no longer

used in this variant.

  Referring to Figure 12 we will now describe a crosspiece implementing the third variant of the method which has been detailed above. This machine comprises, as has already been said, a single vertical insertion station 51 and, as in the preceding machines, a training member 45 allowing the mounting of the rack 57. The operation of this machine is identical in all respects to that that has been said regarding the entry points of previous machines. However, it is distinguished in that at first by means of the member 45 is folded in U the double element 50 according to the representation of Figure 11, then by the vertical insertion head 51 is projected vertically and downwards a blade 33 coming first to bear on the bottom 54 of the double element 50 whose wings 53, 53 ′ are thus folded in a U around the blade 33 as has been said, until insertion into the body 3 correctly positioned by known means directly above the insertion head 51; thanks to positioning means

- 20 -

  conventional in this type of machine, the box is then shifted forward in the AV direction of the advancement of the conveyor 2 to be correctly positioned directly above the insertion head 51 exactly in the median plane of said box ; at this time, the second blade 35 is inserted by the same insertion head 51; the box is again advanced by the same step and positioned by identical means on the conveyor 2 always plumb with the same head 51 to insert the last vertical blade 36 in the median plane of the volume between the last blade and the rear side wall of the box 3. At this instant, the box is released forward by the conveyor 2 to bring it to a case packer which is not shown in the drawings, thus leaving room for a new box 3 open upwards and coming as we said, directly above the vertical insertion head 51

  waiting for a new operation.

  Finally and with reference to FIG. 13, a cross-bit will be described implementing the fourth variant of the method as detailed above. This machine very close to the machine implementing the third variant also includes a single vertical insertion station 51 and a training member 45 allowing the mounting of racks six bottles 7. The operation of this machine is identical in all respects to that which has been described in connection with the preceding machine, at least as regards the means for positioning the boxes 3 under the vertical insertion member 51; on the other hand as regards the latter, the adjustments are provided for extracting from the magazines 52 and 56 respectively double elements 11 and blades 10 in order to constitute racks six bottles 7 which will be successively inserted into the box 3 which is initially positioned under the insertion member 51 so that its front face is at a distance of a bottle diameter, then moved twice over a distance equal to a bottle diameter in the direction of advance AV of the conveyor 2, to receive a first bin 7, then a separator 10 finally

- 21 -

  the second rack 7. When the box is provided with its two boxes 7 and its separator 10, it is then shifted forward on the conveyor 2 towards a case packer not shown in the drawings, thus leaving room for a new box 3 open upwards and coming as we said under the head 51 for a new

insert operation.

  It also goes without saying that the machines which have just been described for implementing one or other of the cross-over methods according to the invention are perfectly capable of inserting lockers providing, once in place, 6 or 12 unequal housings by their horizontal section which can moreover be differently distributed in the internal volume of the box; it suffices to modify the relative position of the fold lines 14,38,55 accordingly to adjust the distance between the wings 12,32,53 of the rack elements 11,31,50 from a maximum position equal to the diameter of the bottle up to a minimum position equal to or slightly greater than the diameter of the neck, if necessary modify the position of the notches on the wings of the rack elements and / or on the separation blades by correspondingly adapting the positioning stops of the boxes at each insertion station 20, 26 or 30, 34 or 51 all operations which are

  generally within the reach of those skilled in the art.

  Modifications of this kind make it possible in particular to create specially braced boxes for receiving bottles head to tail according to any known presentation; for example for a case of 6 bottles, 4

  are cashed ass bottom and 2 ass top, etc ...

  It is easy to understand that in this variant of rack for casing upside down bottles inserted in the same way as for regular lockers, the upper part of certain blades and / or of the wings of the elements opposite on either side of each bottle cashed vertically bottom up, or able to flare as it is introduced into the housing, the section of the lower part of which is slightly greater than

- 22 -

diameter of the neck.

  Horizontal fold lines arranged at a good height on the wings and the blades concerned come

  advantageously facilitate this flaring and therefore5 casing which can be manual or mechanized.
