Description

ASSEMBLY DEVICE

  OF A CONDITIONING MEANS The invention relates to a device for assembling a packaging means, in general box form.

  More particularly, it relates to a device for assembling a packaging means, the latter comprising a wall comprising at least one vertical lateral upright, and a lower spar which is supported on a bottom of the device, which is guided transversely by a lateral wing of the device which extends the bottom vertically upwards and through an edge of an internal partition of the device, and which is positioned longitudinally by a slot, made in the spar, and open downwards, in which is received a wedge which extends vertically upwards from the bottom.

  A device for assembling a packaging means of the aforementioned type is known from document FR-Al-2805521 In this document, the fixing means, or fixing device, comprise lower corner elements, which are provided for 25 assemble the side walls of the packaging assembly, by fitting their lower ends, or lower side members, in the lower corner elements, or assembly device, by a simple downward movement.

  However, this solution does not make it possible to maintain the side walls in a vertical upward direction. In addition, the assembly device also risks being dismantled accidentally during transport of the packaging means, and leading to the separation of the assembly. side walls of the packaging means.

  To respond to these problems, the current solution 5 consists in surrounding the entire packaging means, once assembled and filled, with bands or strapping tapes of the assembly.

  However, the use of these bands results in an additional cost, and a greater volume of waste during the unpacking of the products contained in the packaging means.

  To overcome these drawbacks, the present invention provides a device for assembling a packaging means as described above, characterized in that the lateral wing has a stop which projects transversely inwards and which cooperates with an upper face of the beam to immobilize it vertically.

  In a particular embodiment, the stop is retractable so that it disappears automatically when the longitudinal member is placed vertically from top to bottom. According to another characteristic, the lateral wing is elastically deformable and the abutment is shaped as a ramp so as to automatically cause the deformation of the lateral wing of the device during the positioning of the spar and the retraction of the abutment according to a generally transverse and outward direction. 3 2848988 According to another aspect of the invention, the spar has a notch open in its external lateral face and which is intended to receive the stop.

  The abutment is advantageously a plate of rectangular triangular shape which extends in a vertical plane, the top of which is turned towards the top of the device and the height of which is fixed to the inner lateral face of the wing and the lower horizontal base of which is cooperates with the bottom of the notch.

  According to another characteristic, the notch opens up into the upper face of the beam.

  The bottom, the wing and the stop are molded in one piece, in particular in plastic.

  The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings, in which: FIG. 1 represents a schematic perspective view of a set of packaging or case 25 illustrating the assembly of the side walls.

  Figure 2 is a perspective view on a larger scale of the interior of an assembly device arranged in the lower part of the body. Figure 3 is a cross-sectional view of the beam and the device object of the invention, during assembly.

  4 2848988 Figure 4 is a cross-sectional view of a beam in the assembled position in the device.

  In the description and the views which follow, the terms "vertical", "horizontal", "lower" and "upper" will be used without any limitation being implied, with reference to the figures in order to facilitate understanding of the

description and claims.

  FIG. 1 represents a packaging unit in the general shape of a box, formed of a lower pallet 12 and four side walls 14 each comprising two vertical lateral uprights 16, on which are mounted horizontal beams 18 intended to surround the contents of the packaging assembly 10 The side walls 14 are held together by the cooperation of the longitudinal members 18, upper and lower, and assembly devices 20 positioned at each of the eight lower and upper angles 20 of the packaging assembly 10.

  Each lower and upper spar 18 has, at each of its ends a slot 22 open 25 respectively downwards and upwards.

  As shown in Figure 2, the assembly device 20 object of the invention comprises a horizontal bottom 24 from which extends, 30 vertically upwards, at least one side wing 26, which, in cooperation with the edge vertical of an internal partition 28, transversely guides the lower beam 18 Thus the beam 18 is positioned and immobilized transversely, its two vertical lateral faces 35 being received without play between the edge of an internal partition 28 and the internal face of a lateral wing 26 of the device 20.

  The lateral wing 26 has at its end a wedge 30 5 in the form of a right triangle, the base 31 of which is connected to the bottom 24 of the device 20 and the height 34 of which is connected to the lateral wing 26 This wedge 30 is received in a slot 22, produced in the spar 18, and open downwards. Thus in the assembled position, the side wall 14 comprising the spar 18 is held by its spar 18 which is supported on the bottom 24 of the device, and which is positioned longitudinally by the cooperation of the shim 30 of the device 20 and of the slot 22 of the beam 18 in which it is inserted.

  According to the invention, the lateral wing 26 has a stop 32 which projects transversely inwards from its internal lateral face. The base of this stop 32 cooperates with a notch 34 in the side member 18 to immobilize it vertically. relative to the bottom 24 of the device 20.

  In a preferred embodiment of the invention, the spar 18 has a notch 34 which opens into the upper face of the spar This notch 34 has the advantage of being easy to produce, like the slot, for example by sawing if the spar is made of wood.

  As shown in Figures 2, 3 and 4, the stop 32 is a plate of rectangular triangular shape, whose height 36 is fixed to the wing 26 of the device 20 and whose hypotenuse forms a ramp 38 This stop 32 s inserts into the notch 34 of the side member 18, open in its external lateral face.

  Thus, as illustrated in FIG. 4, in the assembly position 5, the stop 32 is inserted into the notch 34 The base 40 of the stop 32 and the bottom 24 of the device thus prevent any vertical movement of the beam 18 which is thus maintained in the assembly position. The assembly of the packaging means 10 is carried out as follows: The first side wall 14 of the packaging means 10 is placed perpendicular to the bottom 24 of the assembly device 20, so that the vertical upright 16 comes bearing against the corner 42 of the assembly device 20 and that the beam 18 is positioned between the wing 20 26 and the internal partition 28 of the device 20.

  The side wall 14 of the packaging means 10 is then lowered vertically and the inner face of the spar 18 cooperates with the ramp 38 of the stop 32. FIG. 3 illustrates the deformation of the wing 26 of the device which is then caused by the setting in place of the side wall 14, during which the ramp 38 of the stop 32 causes progressive deformation of the wing 26 of the device. The stop 32 is thus made retractable in a generally transverse direction and towards the outside, during the installation of the beam 18.

  When the side wall 14 reaches its final position 35 bearing on the bottom 22, the shim 30 is inserted into the slot 22 of the beam 18, and the stop 32 automatically enters the notch 34 provided for this purpose by the elastic return at the initial position of the wing 26 of the device 20.

  Thus the spar 18 is positioned and held vertically by the bottom 22 and the stop 32, and horizontally by the wing 26, the internal partition 28 and the shim 30 The insertion of the spar 18 into the device 20 takes place simultaneously and at its two ends in two devices.

  The assembly of the three other side walls of the packaging means 20 is carried out in the same way. 15 During assembly, two consecutive walls are held by the same assembly device 20 which has an axis of symmetry of the wings 26.

  Symmetrically, identical assembly devices 20 20 placed on the upper side members 18 of the side walls 14 are slid vertically, the inner part of the bottom 24 being turned downwards.

  Similarly, the wing 26 of the device deforms when the latter is placed on the walls of the conditioning means 10, then returns to its initial position when the stop 32 is inserted into the notch 34.

  The disassembly of the packaging means is carried out by carrying out the operations described above, in reverse order, that is to say by elastic deformation of the wings 26 of the device 20 outwards, then the vertical translation of that - up.

  8 2848988 In a second variant of the invention, the bottom, the wing and the stop are made from the same mold and form a single piece of plastic.

  In another variant of the invention, the notch 34 can be an imprint of a shape complementary to the stop. The present invention offers the advantage of maintaining the 10 walls of a box while saving the strapping tapes. In addition, the solution that is the subject of the invention offers vertical upward maintenance which prevents the device placed on the upper part of the walls is not removed during transport of the packaging means.
