Definitions

  • the invention relates to a method for packaging grouped objects and to a packaging station for implementing said method.
  • the invention relates more particularly to the mail-order industry in which it is necessary to dispatch grouped objects of various shapes and volumes.
  • the packaging will include a quantity and variety of items which excludes any standardization of packaging.
  • the void left in the carton is filled with pieces of expanded polystyrene or foam, for example.
  • the main purpose of the present invention is to present a method of packaging grouped objects of various shapes and volumes which can instantly adapt to the shapes and volumes of the products to be packaged while having a certain rigidity, in particular so that the objects likely to be crumpled can travel in good conditions without risking being folded unduly.
  • This packaging process is particularly suitable for the mail order industry since practically each shipment is specific to the customer's order and therefore, it is necessary to have packaging of variable volumes.
  • packaging method of the present invention can perfectly be used in series, in particular using the packaging station for implementing the method of the invention.
  • the packaging station of the present invention has been specially designed to be automated.
  • the format of the packaging meets the criteria for shipping by post, which minimizes shipping costs.
  • Another object of the present invention is to present a packaging method which can be used regardless of the nature of the objects to be packaged and in particular the method of the present invention can be applied even when the objects are fragile and since the stresses suffered by the objects during packaging are extremely reduced.
  • the storage of the objects to be packaged is optimal and no implementation of wedging means such as the swelling foams or the expanded polystyrene generally used are necessary in the case of the present invention.
  • the packaging method of the present invention is particularly intended for the mail-order industry.
  • a packaging of grouped objects of various shapes and volumes is produced which best adapt to the shapes and volumes of the objects to be shipped and which, moreover, have sufficient rigidity to prevent, for example, fabrics can be wrinkled during transport.
  • FIGS. 1a to 1g illustrate the different phases of the packaging process of the present invention and allow a better understanding of the invention.
  • the packaging process is implemented in shipping stores where the customer's order is grouped in a bin.
  • Figure 1a illustrates the tray 1 in which the objects to be shipped 2 are grouped. Objects 2 correspond to the order placed by the customer.
  • the handling means of the tray 1 have not been shown, however, it can be used conventional means such as a conveyor chain.
  • the tray 1 is deposited above a box 3 which has an upper opening 4 covered by a plastic film 5.
  • the means used to ensure the tensioning of the plastic film 5 are of the traditional type and may in particular be constituted by adjustable clamps arranged on the lateral sides of said box 3.
  • the geometry of the tank 1 preferably corresponds to that of the opening 4 of the box 3 so that the tank 1 when it is placed on the box 3 as illustrated in FIG. 1 b, completely covers the upper opening 4 of the casing 3.
  • the box 3 will advantageously be provided with a rim 6 disposed around the periphery of the opening 4, said rim 6 serving to support the film. It will also be desirable for the tray 1 itself to have a rim 7 so as to ensure perfect positioning of the tray 1 and the box 3, however, note that the plastic film 5 is disposed between the rims 6 and 7. Said rim 6 and the rim 7 will preferably be planes.
  • the plastic film 5 is thus freely placed between the tank 1 and the box 3, and is retained by means of the adjustable clamps with an adjustable force in order to keep it taut.
  • the bottom 8 of the container 1 is then retracted so that the objects 2 contained in the container 1 come to rest on the plastic film 5, as illustrated in FIG. 1c.
  • the retraction of the bottom 8 provided according to the present invention is done by laterally translating the bottom 8 as illustrated in FIG. 1c and shown diagrammatically by the arrow 9.
  • a depression is created in the internal volume 10 of the box 3 as illustrated in FIG. 1d.
  • the box will have been connected to a suction device which is not illustrated by means of a pipe 11.
  • the suction results in a deformation of the plastic film 5 which undergoes atmospheric pressure on its upper face and the weight of the items.
  • the plastic film 5 takes a concave profile containing the objects 2.
  • the plastic film 5 having been applied against the rim 6 of the box 3 in particular by the force applied by the rim 7 of the tank 1, good sealing has been achieved at the periphery of the opening 4 and of the plastic film 5.
  • the suction will be cut off when the upper level 12 of the objects to be packaged reaches the level of the rim 6 of the box 3. In this way, all of the objects to be pack 2 will be included in the box 3 without the objects 2 protruding outside the upper opening 4 of the box 3.
  • the film 5 is allowed to slide between the tray 1 and the box 3, retaining it by means of the adjustable clamps of tension, in order to control the importance of the slip and maintain the desired tension.
  • the suction in the interior volume 10 of the box 3 is stopped, but not the vacuum, and the traction exerted on the sides of the film 5 is adjusted by means of adjustable tension clamps so that the plasticized film 5 remains stretched in a state stationary.
  • the depression created in the interior volume 10 also makes it possible to keep the plasticized film 5 pressed against the rim 6 of the box 3.
  • the level 12 of the upper part of the objects 2 can for example be checked using a feeler 13 which will come to bear on the upper part of the objects 2 to thereby control the level. It should be emphasized, however, that the force applied by the probe 13 to the objects must be low, otherwise there will be constraints on the latter. The role of the probe is only to control the level but it is desirable that it exerts practically no effort. Other means such as a photoelectric cell can also be used to control the level 12. However, a probe 13 whose surface 14 corresponds substantially to the geometry of the opening 4 of the box 3 will however be preferred since the volume and the form taken by the grouped objects 2 can be very variable.
  • the probe 13 and the tank 1 are removed as as illustrated in Figure 1e.
  • the vacuum in the interior volume 10 of the box is also maintained, the plasticized film 5 remains applied to the rim 6 of the box 3 and the objects remain placed in the concave profile taken by the plasticized film 5.
  • a rigid support 14 such as for example a piece of cardboard.
  • the support 14 can be planar since the upper rigid level 12 comes flush with the objects 2. It can be seen that this property of placing the rigid support 14 flush with the objects 2 is achieved whatever the shape or the volume of the objects 2.
  • the plasticized film 5 and the rigid support 14 are secured, that is to say on the periphery of the opening 4 of the box 3.
  • the plasticized film and the cardboard support are secured according to a continuous joint 15 surrounding the objects 2.
  • the plastic film 5 can be cut outside the box 3, for example at point 16 shown diagrammatically in FIG. 1f.
  • the pressure in the volume 10 of the box 3 can be restored as illustrated in FIG. 1g which allows the packaging 17 produced to be released.
  • the plastic film 5 adapts to the geometry and the volume of the products 2 to be conditioned, moreover, the packaging formed has a certain rigidity thanks to the support 14 used.
  • Tests have shown that it is desirable to condition the objects 2 in the tray 1 according to their volume and their shape by placing large flat articles in the background, then the large bulk which corresponds to objects having a fairly large volume in particular in thickness then the small bulk which are the small objects.
  • the tray 1 Initially when depositing the tray 1 on the box 3, we can for example vibrate the tray 1 to promote the storage of objects 2 by filling the interstices with small objects.
  • the packing station for implementing the method described above comprises a box 3 having an opening 4 at the upper part covered by a plastic film 5, said box being further connected to a vacuum pump via, for example, a pipe 11.
  • the packaging station of the present invention further comprises a movable container 1 containing the objects to be packaged, the bottom 6 of which is capable of covering the upper opening 4 of the box 3, said bottom 8 being retractable.
  • the bottom 8 of the tank be formed by two half-combs. That is to say two rows of bars capable of deviating from each other to let the content 2 slide on the plastic film 5.
  • the retraction is faster since the two parts can each be animated in a contrary movement.
  • a layer of protective foam may advantageously be placed in the bottom of the tank, which will thus be placed on the external face of the package 17 or place said layer initially on the film.
  • the objects may be allowed to slightly protrude from the rim 6 of the box 3 after having produced a depression in said box.
  • the probe 13 may exert a certain effort or when the support 12 is put in place, the objects 2 will be pressed to stretch the plastic film 5. The objects will be better held in this packaging by this process.
  • a movable, permeable tray for allow the suction to circulate, the dimensions of its surface are close to those of the box 3.
  • This permeable mobile plate therefore makes it possible to control the depth of the pocket with more precision than with the single depression which is more difficult to control.
  • the method of the invention applies with a sheet of deformable material which can for example be a plastic film or also a net which will be deformed to take a concave profile adapted to the volume, the shape and the nature of the objects to be packed.
  • the deformation can be carried out according to different methods in particular using a pressure variation in the case of continuous film or using mechanical means in the case of threads. These mechanical means being hooks which come to grip the meshes of the net and exert a traction to deform the net for example.
