Description

METHOD AND DEVICE FOR PRODUCING AND SETTING UP

  OF A DIVIDER FOR SEPARATION OF OBJECTS JUXTAPOSED TO PACK;

PACKAGING PROCESS AND INSERTION

  The invention relates to a method and a device for producing and installing a separation divider of the thin partition type interposed between the objects of a group of juxtaposed objects to be packaged; a packaging method using such a spacer; the interlayer thus produced and put in place; and finally, a package including the items to be packaged and

such a spacer.

  The invention applies more particularly to the case where the objects

  are bottles or similar items.

  We already know many embodiments of

  dividers of this type (French patents no. 2,465,653 ,.

  2.475.002, 2.499.948, 2.501.160, 2.503.034, 2.523.548, 2.447.866,

  2,421,116, 2,360,473, 2,389,546, 2,431,959, 2,481,243,

2,541,235).

  Most often the known spacers consist of one or more planar elements associated with each other, by gluing or cooperating cuts or folding. In the case of folding, there is therefore a folding line, generally straight. These known dividers have the drawbacks of requiring a large amount of material, in particular cardboard; to require complex operations of gluing, cutting, association, folding;

  and to be quite unsightly because of their constitution.

  The invention therefore has for objective a spacer which uses the minimum of constituent material and is of an embodiment and

  of a particularly simple installation.

  To this end, the invention firstly proposes a method for producing and installing a separation divider of the thin partition type interposed between the objects of a group of juxtaposed objects to be packaged, characterized by the the fact that one starts from a strip section that is essentially deformable longitudinally over its entire length continuously. Then it is gradually deformed until it is brought along a reference curve and has a surface shape adjusted parallel to a transverse direction and from said reference curve, the strip section thus shaped being

interposed between objects.

  According to a first variant, the section is driven in a longitudinal direction and it is guided transversely,

  gradually along the reference curve.

  According to a second variant, the section is kept at least substantially stationary and its transverse deformation, then optionally longitudinal, is carried out until it is brought

  gradually along the reference curve.

  The invention then relates to such an insert, characterized in that it comprises a section of strip which can be deformed longitudinally over its entire length continuously so that, once associated with the objects of the group of objects to be packaged, it has a area set parallel to a transverse direction, and from a curve constituting its longitudinal cross section, having a radius of curvature

continuously varying.

  Finally, the invention relates to a device for producing and installing such an insert, which comprises, in a first variant: means for feeding sections of deformable strip in a longitudinal direction over its entire length continuously, means for driving the strip section in the longitudinal direction along longitudinal guide means forming a reference curve, transverse guide means for the strip section associated with the longitudinal guide means, support means for a group of juxtaposed objects, placed transversely opposite the transverse guide means, means for transferring a shaped interlayer from the transverse guide means to the support means of the group of objects. In a second variant, the device comprises means for feeding a strip section; means for driving the strip section to an initial stationary position, generally planar; means for transverse deformation of the strip section; means for supporting a group of juxtaposed objects and means for transferring an interlayer shaped by the deformation means to the support means for the group of objects. The invention is therefore based on the concept which consists in gradually deforming a section of strip, by simple curvatures, until it gives it a shape corresponding to the desired final shape, the strip section thus shaped then being interposed between the objects. . This progressive deformation results either from a longitudinal drive of the strip section (first variant), or from its transverse deformation (second variant). As follows from the above, the invention makes it possible to dispense with folding, gluing, generally cutting

needed so far.

  The invention will be better understood with the aid of the appended drawings in which: FIG. 1 is a schematic view only, in perspective, making it possible to clearly illustrate the concept on which is based

  the invention, in the first variant.

  FIGS. 2A, 2B, 2C, 2D, 2E, 2F and 2G are seven schematic perspective views illustrating the successive stages of the process for producing and installing a spacer

  according to the invention, in the first variant.

  FIG. 3 is a partial drawing view, on a larger scale, of a possible device for the production and installation of a spacer, in the first variant. FIGS. 4A, 4B, 4C, 4D, 4E are five schematic views from above illustrating the successive stages of the process for producing a spacer according to the invention, in the

second variant.

  The invention relates first of all to a method for producing and installing a thin partition type spacer 1 interposed between the objects 2 of a group 3 of objects

side by side to be wrapped.

  Objects 2 are preferably bottles or similar objects having the characteristics of being massive, rather slender, of regular shape in particular

  pseudocylindrical, able to remain immobile in stable equilibrium.

  According to the invention, one starts first with a section 4 of strip that is essentially deformable longitudinally over its entire length continuously. Then it is gradually deformed until it is brought along a reference curve 5 and has a surface shape adjusted parallel to a transverse direction T and from said reference curve 5, the strip section thus shaped 1 being interposed

between objects 2.

  In a first variant (FIGS. 1 to 3), the section 4 is driven in a longitudinal direction H and it is guided transversely, gradually along the curve of

reference 5.

  In a second variant (FIG. 4) the section 4 is kept at least substantially stationary, as a whole, and its transverse deformation is then carried out, then, optionally longitudinal,

  until gradually bringing it to the reference curve 5.

  In a preferred embodiment, the objects 2 rest on support means 6 which are of generally planar shape and placed horizontally, the objects 2 extending along

axes 7 directed vertically.

  Objects 2 are grouped in their final configuration a space 8 originally existing between them to allow the setting

in place of tab 1.

  A typical configuration, in particular for bottles, is that comprising six objects 2 distributed in two lines and three rows. However, the invention also applies to other configurations, in particular that with three lines and four rows,

or twelve objects.

  By strip section is meant a piece which, flat, has a generally rectangular shape limited in particular by two small transverse edges 9 and two large longitudinal edges 10. In this case the transverse edges 9 are placed vertically and the longitudinal edges 10 in horizontal planes, when tab 1 is in place. Tab 1 is then

  placed essentially vertically.

  By longitudinal deformation of the strip section 4 is meant a deformation of the section 4 such that the two longitudinal edges 10 are similarly deformed, as is any intermediate line between the two longitudinal edges 10; and that, on the contrary, the transverse edges 9 are not substantially deformed, as is any intermediate line between the two transverse edges 9. The strip section 4 then forms a sheet with one or more more or less pronounced undulations. By section 4 is meant a deformable strip over its entire

2608998 6

  length continuously, the fact that on the one hand, the deformation can occur on any transverse area more or less extended longitudinally situated between the two transverse edges 9 and that, on the other hand, the deformation is progressive and melastically, it that is, the radius of curvature of the strip section 4 varies continuously. This arrangement is such that the strip section 4 can be bent more or less strongly over a transverse section of a certain length, rather than being folded along a localized line. In addition, given the longitudinal flexibility of the strip section 4, it is possible to move longitudinally along the strip section 4 the transverse section on which the curvature takes place, without the latter remaining permanently marked, as opposed to a fold line that remains,

  necessarily marked permanently.

  In view of the above, the longitudinal direction H is generally horizontal and the transverse direction T

generally vertical.

  The adjusted surface formed by the strip section 4 is defined by a segment of transverse direction T, in particular parallel to the transverse edges 9, displaced along the reference curve 5. The reference curve 5 constitutes, at least approximately, that of 'a longitudinal cross section of the interlayer 1 (corresponding to the longitudinal edges 10) once placed on the objects 2. For this purpose, the reference curve 5 has a more or less complex shape determined by the configuration of group 3 objects, so as to be interposed between the

  transverse projections of the objects 2, on a horizontal plane.

  For example in the particular case of a configuration with two lines and three rows of objects 2, as shown, the reference curve 5 begins and ends between the two lines of the configuration. Curve 5 initially forms approximately a positive quarter turn around the object 2 located in the first line and first row; then after an inflection point, forms approximately three quarter of a negative turn around the object 2 located in the first row and second row then after an inflection point, forms approximately three quarter of a positive turn around the object located in second row and second row; then after an inflection point, form approximately a negative quarter turn around the object located in second line and third row. If the object of the ith row and jth row is designated by Li Rj, the curve 5 above is defined by the sequence of references L1R1, L1R2, L2R2, L2R3. We call positive meaning, the meaning of

  clockwise and negative, the opposite.

  In the case of a configuration with three lines and four rows, the curve 5 can be defined by the sequence L1R1, L2R1, L3R1,

  L3R2, L2R2, L2R1, L1R3, L2R3, L3R3, L3R4, L2R4, L1R4.

  In the various configurations, the curve 5 forms, depending on the case, between approximately a quarter turn and approximately three quarter turn. Preferably, the section 4 of the strip is guided or placed around jigs 11 and, once the section 4 of the strip

  shaped, simultaneously, the section 4 is separated from the templates 11-

  and it is inserted between the objects 2 of the group 3 of objects to be packaged, the section 4 of band keeping at least substantially the

same conformation.

  In this variant and as already indicated, there are the objects 2 of the group 3 of objects to be packaged and the templates 11 in the same configuration opposite one another, in the transverse direction, and a relative sliding of the section 4 is carried out shaped strip, in the transverse direction, of the templates 11 to

group 3 of objects.

  In another possible variant, either (first variant) the section 4 of the strip is guided directly on the objects 2 and not by means of templates 11 in which case, the insert 1 is slid over and between the objects 2 directly in in the longitudinal direction, that is (second variant) the section 4 of the strip is placed flat between the objects 2 separated from one another and 2608998 e the objects 2 are moved until they are brought into their final configuration, this movement of the objects 2 causing the

  transverse deformation of the section 4.

  In a first embodiment, one starts from a section 4 of flat strip. In a second embodiment, we start from a continuous strip wound in a reel and cut to length

  desired, to form a section 4.

  The invention also relates to a method of packaging a group 3 of objects in which the objects 2 are arranged in the configuration of the final packaging; at least one interlayer 1 is produced and put in place as described above; these objects 2 are placed in a container such as a crate,

  in particular, at least partially, of cardboard.

  Such a packaging process can also include two other main variants: either insert interlayer 1 before placing the objects 2 in the container, or insert interlayer 1 after having

  placed objects 2 in the container.

  Naturally, the container can be the subject, as far as it is concerned, of numerous variants: American case, tray associated with a plastic cap, all packaging

plastic or whatever.

  The invention also relates to a package comprising such a container, a group 3 of objects 2 juxtaposed in the container and at least one interlayer 1 interposed between the objects 2, this package being

  obtained by the process which has just been described.

  In addition to the advantages already mentioned and resulting from the ease of production of the interlayer 1, such a package has the advantageous characteristic of the possibility of using a section 4 of single strip which can be curved with one or more complete or partial turns and a or more inflection points for the formation, from this single section 4, of a

interlayer 1 three-dimensional.

  In addition, the absence, normally, of folds prevents the creation of lines of weakness. Finally, the curved shape of the interlayer 1 with a suitable radius of curvature makes it possible to give the interlayer 1 the configuration best suited to the objects 2 and to group 3. In particular, the interlayer 1 can be applied to a surface important objects 2 which strengthens

their timing.

  The invention also relates to the interlayer 1. This interlayer 1 comprises a section 4 of strip deformable longitudinally over its entire length in a continuous manner so that once associated with the objects 2 of the group 3 of objects to be packaged, it has a shape of surface adjusted parallel to a transverse direction T and from a reference curve 5 constituting its longitudinal cross section having a radius of

  curvature varying continuously.

  Before being put in place, the interlayer 1 is therefore in the form of a generally rectangular cutout, in elevation. The production method, previously described, aims to give the interlayer 1 a three-dimensional shape of the surface adjusted from the reference curve 5, this three-dimensional shape being adapted, as has been mentioned.

  previously to the configuration of group 3 of objects 2.

  According to another characteristic, the interlayer 1 comprises a section 4 of single strip and the reference curve 5 forms at

minus half a turn.

  According to another characteristic, the interlayer 1 comprises a reference curve 5 having at least one three quarter turn and in particular two three quarter turn so as to separate four

objects 2.

  The fact that the interlayer 1, according to the invention, may comprise one or more half or three quarter turns or even a full or almost complete turn, that is to say, the interlayer 1 is closed on itself- even simply or doubly or even a greater

2608998 1

  number of times is remarkable especially with a tab 1

  comprising a section 4 of single strip.

  The interlayer 1 can be made of single-sided cardboard or also of corrugated cardboard. This embodiment has the advantage of facilitating the longitudinal deformation by * rolling 'of the section 4 of the strip while preventing transverse deformation. The interlayer 1 then comprises, once in place, a self-supporting character thanks to the transverse rigidity

that he presents.

  The invention relates, finally, to a device for producing and installing an insert 1 as described,

  interposed between objects 2 of group 3 of objects.

  This device comprises, in a first variant (FIGS. 1 to 3), corresponding to the first variant of the process in which the strip section 4 is driven and it is guided transversely, gradually, along the reference curve 5: Means supply 12 in section 4 of deformable strip in a longitudinal direction H over its entire length continuously; To drive means 13 of the strip section 4 in the longitudinal direction H along longitudinal guide means 14 forming a reference curve 5; * transverse guide means 15 of the strip section 4 associated with the longitudinal guide means 14; support means 6 of a group 3 of juxtaposed objects 2, placed transversely opposite the transverse guide means 15; and transfer means 16 from a spacer 1 shaped from transverse guide means 15 to the support means 6 of the

group 3 of objects.

  The supply means 12 are constituted, for example, by a store of superimposed flat cutouts or by a mandrel supporting a reel of strip associated with transverse cutting means. The drive means 13 of the strip section 4 in the longitudinal direction comprise, for example, at least one clamp 17 which can open and close; a wired type drive member 18 such as chain, cable or wire carrying and driving the clamp 17; motor means 19 of the drive member 18 such as an electric motor; means for closing the clamp 17 along the longitudinal guide means 14 and for opening upstream and downstream such as projections cooperating with the clamp 17.

  The longitudinal guide means 14 are constituted, by -

  example, by a gutter, groove or the like with which

  cooperates the wired drive member 18.

  The transverse guide means 15 are constituted, for example, by templates 11 of shape and configuration corresponding at least substantially to that of the objects 2 of the

group 3 of objects to be wrapped.

  In one possible embodiment, the device comprises a plate 21, in particular an upper horizontal plate supporting on the one hand the longitudinal guide means 14 and, on the other hand, the jigs 11, these extending essentially vertically and downwards , the longitudinal guide means 14 passing between

the templates 11 by separating them.

  Also, in one possible embodiment, the transfer means 16 comprise at least one finger 22 or the like movable doubly, on the one hand longitudinally, that is to say transversely to the direction of the jigs 11, in particular in a horizontal plane so as to be able to be placed against the upper longitudinal edge 10 of the shaped strip section 4 and thus interfere with it, on the other hand, transversely, in particular

2608998 12

  vertically. Finally, preferably the spacing between the transverse guide means 15 and the support means 6 is determined as a function of the size of the objects 2 to be packaged, so that during the transfer of the section 4 of shaped strip, it may be simultaneously on the transverse guide means 15 and interposed between the objects 2, which makes it possible to preserve this conformation. Reference is made to FIG. 1 which illustrates the concept on which the invention is based in the first variant, namely, the use

  of a section 4 of strip, then (arrow A) the deformation.

  progressive of this section 4 of strip by means of the templates 11 and finally (arrow B) the transfer of the interlayer 1 shaped on

  group 3 of objects 2, the conformation being maintained.

  Reference is made to FIGS. 2A to 2G, which illustrate in more detail the implementation of the method in the case of a group 3 of six objects in the two-row and three-row configuration, with

  from a section 4 of strip coming from flat cutting.

  At the start, (FIG. 2A), the sections 4 of strip are placed in the supply means 12 in the form of a store and a section 4 is removed from the store 12 by means of a gripping device 23 such as that which does not is not possible with the techniques

  currently known. suction cups.

  Then (FIG. 2B), the section 4 thus grasped is in the initial position, in particular vertical, the upstream transverse edge 9 - relative to the direction of longitudinal advance H being pinched between two drive cylinders 24,25, one of which , by

  example the cylinder 24, is retractable.

  The pivoting of the cylinders 24, 25 allows the advancement of the section in the longitudinal direction H until its transverse edge 9 upstream comes to be taken in the clamp 17 in the open state then being in the extreme upstream starting position

on the reference curve 5.

26089U 13

  Then (FIG. 2C) the clamp 17 is driven, from its extreme upstream position, and as soon as it is set in motion closes thanks to the means 20, such as protrusion, by gripping and thereby pulling the section 4 of strip. It is then possible

retract the cylinder 24.

  Then (Figure 2D), the clamp 17 continues its movement along the reference curve 5. The section 4 slides on the templates 11 gradually taking the desired shape, the reference curve 5 passing in line with the free spaces existing between the templates 11. In this situation, the transfer means 16

  are retracted so as not to interfere with the clamp 17.

  To allow the passage of the clamp 17, the templates -11 are preferably hollowed out, laterally and upwards thanks to

dropouts 26.

  In addition, to allow additional positive maintenance of the section 4, provision may be made for its lower longitudinal edge 10 to slide and rest on a horizontal plate 27,

  retractable located under the templates 11.

  When the clamp 17 arrives in the extreme downstream arrival position on the reference curve 5 (FIG. 2E) it is open, thanks to the

means 20 such as projection.

  The strip section 4 is then wound around the templates 11 according to the desired final configuration. It is then possible to retract the plate 27 and to slide the fingers 22 of the transfer means 16 in the horizontal direction perpendicular to the longitudinal direction H so as to bring them against the

longitudinal edge 10 upper.

  Then (FIG. 2F) the fingers 22 of the transfer means 16 are moved vertically and downwards, thus driving the interlayer 1. Beforehand, a group 3 of objects 2 was

  arranged under the templates 11 with the same configuration.

  Preferably, tab 1 begins to be inserted in

2608998 14

  group 3 of objects while it is still inserted between the templates 11 so that the shape which has been given to it is maintained subsequently. Referring to Figure 3 which shows in more detail the device shown in Figures 2A to 2G. Ways

  feed 12 are store type for flat cuts.

  Associated with it is a gripping device with suction cups carried by drive means 28. the two cylinders 24, 25 have a vertical axis bearing against one another. The cylinder 24 is carried by a horizontal lever 29 pivoting about an axis 30 cooperating with a cam 31 carried on a vertical axis 32. The axis 32 also includes, wedged, a drive pulley 33 driving the cylinder 25 by means of a

strap or the like 34.

  The drive member 18 is for example an endless chain stretched between two end sprockets 35, 36 to vertical axes, at least one of which is motor. One of the strands between the two pinions constitutes the curve 5 while the other allows the clamp 17 to return from the extreme downstream position to the

extreme upstream position.

  In the vicinity of the pinions 35, 36 and in the loop formed by the drive member 18 are located projections constituting the means 20 with which the clamp 17 cooperates in two parts or jaws. The projections constituting the means 20 are ramps on which the clamp slides to open it, the clamp normally being permanently biased in the position of

closing by a spring.

  The transfer means 16 comprise several parallel fingers

  22, each passing between two adjacent rows of templates 11.

  These fingers are carried by a carriage 37 mounted doubly sliding along vertical 38 and horizontal 39 tracks,

  driven by jacks or the like.

  In the first alternative embodiment described (Figures 1 to 3), the section 4 is deformed on the one hand gradually, that is to say

2608998 15

  for an increasingly large longitudinal part up to the entire section 4 and, secondly, definitively in the sense that as soon as a part of the section 4 is deformed, it has its

final deformation.

  On the contrary, in the second embodiment more fully described below, the section 4 is completely deformed on the one hand, that is to say for its entire length - and this from the start - and, on the other hand part, gradually in the sense that the section 4 in its entirety passes only gradually from its

  initial form to its final form.

  The device for producing the interlayer comprises, in the second variant: supply means 12 in strip section 4, of the same general type as described above, drive means 13 for section 4 in the longitudinal direction H along the guide means 14 not forming the reference curve 5 but generally straight; transverse deformation means 15 of the strip section 4 such

only templates 11.

  Unlike the first variant described, the templates 11 of the second variant are movable longitudinally and transversely between an initial position (FIG. 4A) or they are spaced longitudinally and transversely from each other allowing the longitudinal passage 4 between them of flat strip, thanks to the drive means 13 and a final position (FIG. 4E) where they are brought close to each other longitudinally and transversely, in the configuration corresponding at least substantially to that of

  objects 2 of group 3 of objects to be packaged.

  To move from the initial position to the final position, the templates 11 are driven according to an appropriate kinematics which can be the subject of numerous variants. For example, in the case of a group of six templates 11 distributed in two lines and three rows (with the designation LiRj as defined above), it is first possible to place a section 4 between the templates 11 in the initial position (Figure 4A); then (figure 4B) bring together

2608998 16

  the two template lines 11 (respectively L1R1, L1R2, L1R3 on the one hand, L2R1, L2R2, L2R3 on the other) until they are applied to the strip section 4, on both sides (arrow C). Then one can operate an overall pivoting of the two central templates 11 L1R2 and L2R2, that is to say of the central row, by 180 (FIGS. 4C and 4D) (arrow D) which has the effect of giving the section 4 of band, a general form of S in its median transverse part. Then, one can operate a longitudinal approximation of the end jigs 11 of L1R1, L2R1 on the one hand, L1R3, L2R3 on the other hand on the central jigs 11, until bringing the jigs 11 in close proximity to each other and thus realize the deformations of the transverse end portions of the section 4 (arrow E) (FIG. 4E). To this end, the device comprises means for guiding, driving, blocking the jigs 11 such as slides for the axes of these jigs, endless chains carrying these axes and motors for driving the endless chains. . Whether in one or the other of the two variants, the device comprises: means 12 for supplying sections 4 of deformable strip in a longitudinal direction H over its entire length continuously; drive means 13 for the strip section 4 in the longitudinal direction H along the longitudinal guide means 14; means suitable for causing the strip section 4 to have a surface shape adjusted prallelly to a transverse direction and from a reference curve 5;

  support means 6 for a group of juxtaposed objects 3.

  Either the means suitable for causing the strip section 4 to have a surface shape adjusted from the reference curve 5 are placed near the support means 6, so that the strip section 4 can be shaped directly on the objects 2, or they are separated from the support means 6, these means comprising templates 11, and the device comprising transfer means 16 of an interlayer 1 shaped from said means suitable for causing the section 4 of strip to have the shape of a surface settled on

  means 6 support for group 3 of objects.

  In the first variant, the longitudinal guide means form the reference curve 5, the means capable of causing the strip section 4 to have a surface shape folded back from the reference curve 5 comprising transverse guide means 15 of the strip section 4 associated with the means

longitudinal guide 14.

  In the second variant, the longitudinal guide means are essentially rectilinear, the means capable of causing the strip section 4 to have a surface shape adjusted from the reference curve 5 comprising templates 11 or objects 2 movable longitudinally and transversely between an initial position where they are separated from each other and a final position where they are moved towards each other

  in the configuration of the objects 2 to be packaged.

  As has been clearly understood, the templates 11 are in the first variant essentially fixed in position while they are displaced with longitudinal and transverse sliding in the second variant. But, in one as in the other variant,

  the objects 2 themselves can be substituted for the templates 11.
