Description

FOLDABLE CONVEYOR WITH ALVEOLAR STORAGE,

  ESPECIALLY FOR THE TRANSPORT OF ASSEMBLY PARTS

FOR THE AUTOMOTIVE INDUSTRY

  The present invention relates to a collapsible container with honeycomb storage.

  It applies in particular, although not excluded-

  The transport of parts for the automotive industry. In the context of the invention, the term "mounting part" must be understood in its most general acceptance: bodywork parts proper, dashboards, upholstery parts, etc. In all cases, the container must be able to accept a large number of pieces, pieces arranged in "cells", that is to say boxes of predefined shape adapted to that of the pieces to be transported. Access must be possible either from the top of the container or by

  the sides according to the type of parts to be transported.

  It must also be foldable, so that it can be stored in a minimum of space, after use, and can minimize the costs of empty transport. In the known state of the art, containers have been proposed with a rigid metal frame supporting a cell tarpaulin. The general configuration of such a container is such that it consists of a base with foldable uprights equipped with a metal frame, parallel to the plane of the base.

  and supporting tarpaulin cells.

  However, this lifting system allows only one direction of tensioning of the cells and does not

  therefore not suitable for all needs.

  Furthermore, it should be remembered that such containers must have great flexibility of use and great reliability. The number of parts used must be minimal and the cost reduced. They must be easy to implement, in particular to allow easy handling. Finally, they must exhibit resistance

  sufficient for wear, despite significant stress.

  The invention sets itself the goal of responding simultaneously-

  to these needs, some of which seem, a priori,

antinomics.

  To do this, the invention provides for supporting the cells directly by the vertical uprights of the container and no longer by an upper frame parallel to the plane of the base. More precisely, the cells are supported by these uprights by means of a mobile beam mounted on slides forming an angle

determined with the vertical.

  According to a first characteristic of the invention, the deployment of the cells is carried out simultaneously with the

deployment of amounts.

  According to a second characteristic of the invention, a tensioning device (with eccentric cams in a preferred variant of the invention) drives the mobile beam on the slides, which makes it possible to tension all of the cells in two directions if the slide is inclined, since the tension force can be broken down into a vertical component and a

horizontal component.

  The invention accommodates with cells accessible both from above and laterally. In this latter variant, the container can be provided with two (or more) independent levels of cells. It suffices to provide two setting devices

voltage, one for each level.

  The tensioning device can act either on the cells themselves or via cables

  or similar organs, to which the cells are suspended.

  The invention therefore relates to a collapsible container with honeycomb storage comprising a rigid base and vertical uprights, characterized in that said honeycomb storage comprises at least one independent level of honeycombs of flexible material, in that said vertical uprights comprise two sections, a first fixed section secured to said rigid base and a second section movable in rotation about a horizontal axis, and in that it comprises means for attaching each of said independent levels of cells to the movable sections, so as to obtain the folding and deployment of said cellular storage simultaneously with the folding and deployment of said mobile sections during their rotation

around said horizontal axes.

  Another subject of the invention is the application of such a container to the transport of mounting parts for

automobile industry.

  The invention will be better understood and other characteristics and advantages will appear on reading

  the description which follows with reference to the appended figures,

  among which: - Figure 1 illustrates an example of container according to the invention according to a first embodiment; - Figures 2a to 2f are detail figures to explain the operation of the constituent parts of the container of Figure 1; - Figure 3 illustrates an alternative embodiment of the first embodiment of a container according to the invention; - Figure 4 illustrates an example of container according to the invention according to a second mode

of achievement.

  FIG. 1 illustrates the general structure of a container 1 according to the invention according to a first mode

of achievement.

  It comprises a metallic structure 3 comprising a base 30 defining a substantially rectangular frame

  and vertical uprights at each end of this frame 3.

  According to a first characteristic of the invention, the vertical uprights consist of two sections: a fixed lower section 31, that is to say fixed to the frame 30, and a section 32, foldable by rotation about horizontal axes, A1 and A2, respectively. The foldable sections, 32, are therefore foldable, one towards the other, in a direction parallel to the largest dimension of the container (in the example described), that is to say according to the arrows f, to using a device which will be detailed below.

  The base, 30, as well as the vertical uprights, 31-

  32, advantageously consist of hollow angles of

rectangular section.

  The container 1 comprises a set 2 of cells 20.

  These cells 20, in the example of FIG. 1, are defined, on the one hand, by a first set of vertical walls 22 parallel, and, on the other hand, by a second set of oblique walls 23, also parallel between they. The upper ends of the vertical walls are all attached to a horizontal wall 21, forming the

  upper wall of the set 2 of cells 20.

  This assembly 2 is fixed, in its lower part, to the front and to the rear of the frame 30, by a set of bars 46 and nuts 460. I1 is also fixed, in its upper part, on the two sides (front and rear) of the container 1, a tensioning device 4 and a fixed beam 33 disposed horizontally between two upper sections, 32, of the vertical uprights. In practical terms, in the example described in FIG. 1, this fixing is achieved by means of a flexible wall section 24, wound on a tube 45. This tube 45 is itself subject to the setting device. tension 4 by

  through pairs of 400 nut nuts.

  The walls, 21 to 23, forming the cells 20 can advantageously be made of tarpaulin, for example polyester coated with polyvinyl chloride (PVC) or any other similar material. The different walls, 21 to 23, can be heat-sealed together, to form

in particular the cells 20.

  The inclined configuration of the cells 20, illustrated by FIG. 1, is of course not limiting: one could just as easily realize them, for example, in the form of rectangular housings (horizontal walls 23 and vertical walls 22) as it will be shown below in

  the variant embodiment illustrated in FIG. 2.

  In Figure 1, the container 1 is shown in the unfolded state. The assembly 2 of the cells 20 therefore presents itself in the configuration of a rectangular parallelepiped. It is easy to understand that, according to one of the important characteristics of the invention, when the upper sections 32 of the vertical uprights (as shown by the arrows f) are folded around their axis of rotation, A1 and A2, this operation will also cause folding back cells 20, driven

by these amounts.

  Advantageously, the upper end of the movable vertical arms 32 is provided with horizontal arms 37. These themselves are provided with damping pads 39, for example made of rubber. The length of the horizontal arms 37 is adapted to the distance separating the axes of rotation, A1 and A2, from the fixed frame 30, so that, when the arms 32 are folded, the damping pads 39 rest on the frame 30 and the foldable sections 32 of the uprights are substantially horizontal. The buffers 39 make it possible to absorb shocks when the arms 32 rock around their axis of rotation, A, and A2, during the folding of the

container 1.

  Conversely, when the container 1 is deployed, the set 2 of cells 20, while being retained from the bottom (bars 46 and fixing means 460), will be attracted by its upper part by the delivery device. in tension 4 and the fixed beam 33. The deployment of the system 2 of cells 20 will therefore be simultaneous with the deployment of the container 1

well said.

  The container 1 also comprises, in the variant embodiment described in FIG. 1, a lateral protection device constituted by a movable curtain (not visible in FIG. 1) controlled by an unwinder 5, placed at the bottom of the frame 30, this on the two sides of the container 1. Once the parts to be transported are placed in the cells 20, the movable curtain is pulled upwards and fixed in this position using hooks 38, fixed or welded to the horizontal arms 37, which protects the interior of the cells 20 from dust, as well as the parts placed there. Advantageously, the unwinder 5 is provided with a spring or a similar member, which allows automatic winding of the curtain. The latter can be made of a similar material otherwise

  identical to that of alveoli 20.

  Finally, according to an additional characteristic of the invention, there is disposed under the base 30 a member 6 of the "pallet" type, that is to say allowing the transport of the container 1 using a pallet-carrying trolley . This member 6 consists of arcs 60 having lateral orifices 61 and orifices 62, located at the front and at the rear of the container. These orifices, 60 and 61, have dimensions such that they allow the introduction of the forks with which the pallet carrier carriages are provided, these dimensions being standardized. Furthermore, the frame 30 is provided with feet 35, extending the lower sections 31, these feet serving to

container stacking.

  The tensioning device 4 will now be described in more detail with reference to FIGS. 2a to 2f. The elements common with FIG. 1 have the same references and will only be described again as necessary. Figure 2a shows, partially, the tensioning device 4, in front view (viewed from the front or rear of the container 1, the latter being provided with a device at both ends of the assembly 2 cells 20, in the example described). It comprises at least two bearings 34, subject to the fixed horizontal beam 33, in the end zones thereof (only one being visible in FIG. 2a). The bearings 34 can be welded to this fixed beam 33. The tensioning device 4 comprises an axis 41 supported by the bearings 34, the latter being in rotation in a ring 340. It finally comprises an operating handle 44 fixed to the axis 41, for example by welding, and disposed in a central zone of this axis 41. Optionally, intermediate bearings can be provided in an zone close to the handle 44, for example on either side thereof, as shown in dotted lines in Figure 2a. Similarly, the operating handle 44 can be provided, if necessary with a protective sheath (not shown). Finally, the axis 41 can be provided with several handles, for example two, in particular if the

  container 1 has a large width.

  Figure 2b is a section of Figure 2a along "AA". This FIG. 2b shows the two possible positions of the operating handle: in the high position, 44, and in the low position, 44 '. This operating handle being secured to the axis 41, when it passes from the high position to the low position, the axis 41 turns on itself and therefore drives the eccentric cams: positions 42 and 42 ' , respectively. The movable beam, 40-40 ', being supported, by means of a tab, 43-43', on the external surface of the eccentric cam passes from position 40 to position 40 '(respective positions 43 and 43 'of the aforementioned leg). More precisely, the aforementioned tab comprises a vertical section, 430-430 ', welded to the movable beam, 43-43', and an inclined section, 431-431 ', bearing on the periphery of the eccentric cam, 42 -42 '. Advantageously, provision is made for a reinforcement, 432-432 ′, connecting these two sections, to

stiffen the tab.

  As shown more precisely in FIGS. 2c and 2d (FIG. 2c being the section along "CC" in FIG. 2c), the movable beam 40 has, at its two ends, an end piece 47. This end piece 47 is inserted in a slide 36 having the shape of an inclined "U", of axis A forming an angle ci with respect to the vertical, that is to say with respect to the vertical uprights 32. The slide 36 is integral with the section of vertical upright 32 (for example by welding). The only possibility of movement of the end piece 47 therefore consists of a translation along this axis A, in one direction or another. When the operating handle is actuated (from the high position 44 to the base position 44 ′, or vice versa), the latter will drive the axis 41 in rotation, in one direction or the other, and thereby the eccentric cams 42. These transform the rotational movement into a

  translational movement communicated to the mobile beam 40.

  However, the latter can only move in a direction parallel to the axis A (see Figure 2d), that is to say inside the two branches of the "U" of the inclined slide 36. The slide 36 is open in its upper part to allow the insertion of the end pieces 47. The translational movement of each end piece 36 is limited by the bottom of the slide 36 and by a screw 48 or a similar member, integral with the section of the vertical upright 32 and disposed near the mouth of the slide 36 after insertion of the end piece 47. In other terms, the end piece 36 can move back and forth inside the slide 36, depending on the high position, 44, or low,

44 ', from the operating handle.

  If one refers more particularly to FIG. 2e, one notes that, when the end piece 36 passes from the "low" position O to the "high" position 0 ', the latter exerts a traction force F on the section of sheet 24 along the axis A, that is to say on the upper part of the set 2 of cells 20. This force is exerted on each side of this set if the setting device

  voltage 4 is split, as shown in Figure 1.

  In an alternative embodiment not shown, a single tensioning device is provided, the other end of the assembly 2 being simply attached to a fixed horizontal beam (via the winding 24, the tube 45 and the

fixing means 400).

  This force F, as it is well known, can be divided into two orthogonal components: a vertical component Fv and a horizontal component FH, if the angle a is different from zero or 90 degrees. As an example, we can choose the angle c = 45 degrees, which distributes the tensile force evenly along the horizontal and vertical axes. More generally, the distribution of forces along these two axes depends on the angle c: FV, = Fcos (C) and FH = Fsin (cL). It is easy to see that, thanks to this important characteristic of the invention, the assembly 2 of cells 20 is energized, simultaneously according to

vertical and horizontal axes.

  Advantageously, the eccentric cams, 42-42 ', are provided with a flat, 421-421', on which the inclined part, 431-431 'rests, with the tab, 43-43', when the handle of maneuver is in low position 44 '(tension state). This arrangement provides self-locking in the tension state. Indeed, the assembly 2 of cells 20 being energized, when one passes from the cylindrical surface to the flat 421 ′, the end piece 47 will be returned to the rear, which ensures locking in this position, this as long as the operating handle 44 'is not actuated

  in reverse (to position 44).

  Figure 2f is a figure (section "BB" of Figure 2c) showing the detail of the attachment of the top of the assembly 2 of cells 20 to the setting device

  tension 4, and more particularly to the mobile beam 40.

  To do this, use is made of a tube 45, advantageously of circular section, or a similar member, threaded on one end 24 of the upper wall 21 (and / or of the vertical wall 22) wound on itself and heat-sealed at 240, for example. Several sets "screw-locknuts" 400 pierce this tube 45 (for example three regularly

  spaced: see figure 1), as illustrated in figure 2f.

  It is this flexible wall section 24 which transmits the tensile force to the set 2 of cells 20. The circular section of the tube 45 allows the "ring" formed by the folded section 24 to slide / rotate. external surface of the tube 45, without excessive friction and, therefore, with limited risks of damaging the flexible material, during the deployment of the container 1 and during the subsequent operations of placing under

  tension of the set 2 of cells 20.

  A similar assembly (not visible in FIG. 1) can advantageously be used to fix the lower ends of the assembly 2 of cells to the frame 30, via the

  beam 46 and the fixing means 460.

  Figure 2g is a cutaway illustrating in detail the specific provisions previously

  described with reference to Figures 2a to 2e.

  Figure 3 illustrates, partially broken away, an alternative embodiment of a container 1 'according to the invention, according to the first mode. The elements common to the previous figures have the same references and will only be described again as necessary. The essential difference is constituted by the fact that the cells, 20 ′, of the assembly, 2 ′, are rectangular in shape, that is to say made up of vertical walls 22 (as before), and of horizontal walls,

  referenced 23 ', instead of oblique walls (Figure 1: 23).

  A second difference is constituted by the fact that two operating handles 44 have been provided instead of only one, arranged at the ends of the axis 41 and four bearings 34, arranged in pairs, on either side of the of them

operating handles 44.

  With this exception, the tensioning device, referenced 4 ', is strictly identical to that previously described and there is no need to redesign its operation. In this Figure 3, there is shown an additional advantageous arrangement. In fact, especially for very long containers 1 ′ and / or for transporting heavy objects placed in the cells 20 ′, it may be necessary to support the assembly 2 ′ of cells 20 ′ and the upper wall 21. To do this, cables 210 are provided (shown in dotted lines). These cables 210 are threaded in rings or eyelets 211 integral with the upper wall 21. The cables 210 are attached at their two ends to the tensioning devices 4, for example using the fixing means 400. These cables 210 therefore participate in the tensioning of the wall

upper 21.

  Of course, this arrangement can also be

  adopted for the variant shown in FIG. 1.

  In FIG. 3, the side curtains, referenced 50, have been shown explicitly. A first side curtain (right in FIG. 3) is shown rolled up, while the second side curtain (left in FIG. 3) is shown unwound. The upper part of the curtain 50 is wound on a horizontal rod 51 and has openings 55. The end of the rod 51 is provided with lights 56 allowing it to be threaded on vertical guide cables 52 whose upper ends are fixed to the horizontal arms 37. These cables 52 guide the curtain 50 in its vertical translational movement. The openings 55 serve to suspend the curtain 50 on the

  hooks 38 fixed to the horizontal arms 37.

  Advantageously, the cables 52, front and rear pairs, are interconnected by horizontal elastic tensioners 53, via references 54 arranged at the four ends of the container 1 '. When the container 1 ′ is in the unfolded state (FIG. 3), the tensioner 53 is in the tensioned state. When the container 1 'is folded, it contracts and keeps the cables 52 in tension, despite the fact that the mobile vertical uprights 32 are folded down. In this Figure 3, there is also shown explicitly the members 7 allowing the folding and deployment of the vertical movable uprights 32 around their

axes of rotation, Al or A2.

  In the example described, as illustrated more precisely in FIG. 2h, a first member 71 is provided, in the form of a vertical tongue comprising an inclined base 710. This member 71 is integral with the movable section 32 of the vertical uprights 3. A second member 70 is provided, in the shape of a "C", integral with the fixed section 31 of the vertical uprights. The walls

  horizontal of the "C" are welded to the wall of the section 32.

  This member 70 traps a vertical pusher 72 mu by a spring 73. An orifice 700 is provided in the upper wall of the part 70, so that the vertical pusher 72 can press on the base 710 of the tongue 71, which provides locking and locking in folded and unfolded positions of the container 1 '. Figure 4 illustrates an example of a 1 "container

  according to the invention, according to a second embodiment.

  The elements common to the previous figures have the same references and will only be described again as

need.

  A first difference is constituted by the fact that several independent levels of assemblies, 2 "a and 2" b, of cells, 20 "a and 20" b can be provided (two levels in the example described, associated to references "a"

and "b", respectively).

  A second difference is constituted by the fact that the cells, 20 "a-20" b, are in the form of pockets in the shape of "U" arranged side by side and suspended from cables or the like, 7a-7b. It is therefore no longer the tissue forming these cells which is directly subjected to

  the tensile strength, but the aforementioned cables.

  The tensioning devices, here referenced 4a and 4b, for the upper level and the lower level respectively, can be strictly identical to those used in the first embodiment. Also, in order to simplify the drawing, we have not referenced

  than the essential components of these devices.

  The suspension cables, 7a and 7b, are fixed to the mobile beam 40a by any suitable conventional member, by

  example the nuts referenced 400a.

  The adjacent vertical walls of the U-shaped pockets forming the cells, 20 "a and 20" b, may or may not be glued or heat-sealed together. By cons, there are provided orifices, 200a and 200b, at their upper ends, in which the cables are threaded, 7a or 7b. The number of cables, 7a or 7b, per level depends on the various parameters to be taken into account: in particular the dimensions of the 1 "container and the weight of the parts in front

  be introduced into the cells, 20 "a and 20" b.

  A priori, the cells, 20 "a and 20" b, can slide freely along the cables, 7a and 7b. This arrangement can prove to be advantageous: the unused cells take up a minimum of space in thickness and can be pushed back, for example, on one of the ends of the 1 "container. It is also possible to introduce pieces of thickness different in consecutive cells, 20 "a and 20" b, naturally in a

  given range, without losing space.

  The folding of the 1 "container and its deployment causes, according to one of the main characteristics of the invention, respectively the folding and the deployment of the assemblies, 2" a and 2 "b, of cells, 20" a- 20 " b, similarly to what has been described As in the case of the first embodiment, the lateral zones are protected by a removable curtain 50 controlled by the reel 5. The operation of this curtain is identical to that described for the first mode of

  production. There is therefore no need to rewrite it.

  Advantageously, a lower member 6 of the "pallet" type is also provided to facilitate transport of the

1 "container.

  However, as the cell levels, 20 "a and 20" b, do not, strictly speaking, have vertical walls, in particular if the container 1 "has been subdivided into two levels, it is necessary to provide a protective wall, at the front and at the rear, if it is desired to prevent dust or any other polluting material from entering these cells. In FIG. 4, only the wall 25a-25b is visible, wall which one can qualify "before". It is also shown in partial cutaway, so as to leave visible the lower tensioning device 4b. Each device, 4a-4b, comprises,

  in the example described, two operating handles, 44a-44b.

  The wall 25a-25b can be flexible or rigid. In the latter case, it must be in two parts: an upper part, 25a, and a lower part, 25b, the respective heights of which are adapted to the lengths of the upper, 32 and lower sections, 31, of the vertical uprights, which to allow folding of the container 1 ". In addition, the upper wall 25a must include an opening or be itself divided into two parts (as in the case of the example illustrated in FIG. 4), so as to allow the accessibility to the lower tensioning device

  4b, at least to the operating handles 44b.

  Likewise, since the cells, in particular the cells, 20 "a, of the upper level, are not provided with upper walls, it is necessary to provide one, 26, if it is desired to prevent dust or any other polluting material to enter these cells. This wall 26 can be attached at its ends, front and rear, to the mobile beams 40a of the upper tensioning devices 4a, which will make it possible to tension them at the same time as the cables 7a. it is not necessary to provide additional tensioning cables as in the embodiment illustrated in FIG. 3, this function being already provided by the cables 7a and 7b, for the upper and lower levels. It is also noted that the end pieces 47, of the end of the mobile beam 40 has been shown to be horizontal. This is the case for the axes A of the "U" slides 36. In fact, it is no longer necessary to obtain a tension force having co vertical and horizontal components, as in the case of variants of the first embodiment (see FIG. 2e). It is only necessary that the cables, 7a and 7b, undergo a tension according to the

single horizontal direction.

  On reading the above, it is easy to see that the invention achieves the goals it has set for itself. It should be clear, however, that the invention is not limited to the specific examples of embodiments

  described, in particular in relation to FIGS. 1 to 4.

  In particular, the tensioning devices can be omitted, for example for small containers, the deployment and locking of the movable sections of the vertical uprights in this state can then be sufficient to ensure the necessary tension. Similarly, other embodiments of the tensioning device can be used without departing from the scope of the invention, for example by cables actuated by grasshoppers or mini winches allowing adjustment

voltage variable.

  Finally, the usable materials are essential-

  related to the specific application envisaged and particularly

  a simple technological choice within the reach of the skilled person. It is advantageous to choose plasticized tarpaulins, for example polyvinyl chloride (PVC). It should be noted that the choice of materials may be imposed by existing standards (for example for the preservation of

  environment) for some applications.

  It should also be clear that, although particularly

  Rely suitable for transporting parts for the automotive industry, the invention cannot be confined

to this single type of applications.
