Definitions

  • the present invention relates to a method for individually packaging mattresses in such a way as to ensure ease of transport of the mattress and a small overall size thereof.
  • the invention also relates to an individual mattress package.
  • a known method of individually packaging a mattress includesthe steps of inserting the mattress into a flexible and sealable wrapper, compressing the wrapped mattress by squeezing compression means to reduce the thickness of the mattress within limits compatible with the elastic structure of the mattress, and to remove air from the inside of the wrapper, thereafter sealing the wrapper, rolling up the squeezed and sealed mattress, stabilizing the rolled up shape; and placing the rolled mattress in a container therefor.
  • the compression can be produced by squeezing, and the remaining air is subsequently at least partially removed by suction with a suction or vacuum pump. In other methods, welding is effected without removal of air by suction, expulsion of the air with the press being sufficient.
  • the wrapper shall be air-tight, and it may be double, i.e.
  • the welding of the wrapper may be effected after the removal of air by suction, or in two stages, a first stage effecting a partial closure and allowing air passage during the suction operations.
  • the stabilization of the rolled-up shape may be produced by the use of tapes, closing rings surrounding the rolled-up mattress, or with adhesive tape which may be disposed around the rolled-up mattress or, simply, as strips applied to the outside edge which extends longitudinally of the rolled-up mattress.
  • the method of packing to be described may be adopted for many types of mattresses, and particularly for those which have an intermediate layer of rubber or a synthetic elastic foam resin and, possibly, outer layers of artificial or natural fibres on the surfaces ensuring the comfort of the user.
  • a mattress of this type can resume its normal expanded, smooth shape within the space of a few hours after the wrapper which has kept it in a low vacuum has been torn off.
  • the invention provides an improved method of packing, which includes the steps of: reducing the thickness of an elastic structure of the mattress by pressing and feeding means cantileverly projecting; fitting a cover on said structure and on said pressing means to complete the mattress, said cover comprising foam padding with inside film and a closure means; fitting a flexible and substantially air-tight wrapper on the outside of said cover; moving away the mattress with said cover and said wrapper from said pressing and feeding means; closing the cover by said closure means; flattening the mattress together with its cover and the flexible wrapper; inserting the flattened mattress between a rolling-up mandrel and a cylinder operating the compression by rolling and being elastically pushed toward said mandrel; rotating said mandrel and rolling-up Q n said mandrel said flattened mattress by compressing it by means of said cylinder which performs compression by rolling; circularly applying at least two adhesive ribbon-shaped strings at spaced apart positions around the rolled mattress in order to stabilize it; and axially withdrawing the mandrel from the rolled mattress and
  • the invention also includes an improved package for an individual mattress including an outer container, a mattress, a wrapper enclosing said mattress and sealingly . holding said mattress in a compressed condition, and retaining means for holding said mattress and wrapper in a rolled-up configuration, said retained, rolled and wrapped mattress being received in said outer container.
  • the improved package includes an outer container, a mattress, a wrapper enclosing said mattress, said mattress and said wrapper being in a compressed and rolled-up configuration, a ribbon-shaped film coupled to said mattress and rolled up at least partially together with said mattress and enveloping the rolled mattress with at least one convolution, and at least two regaining adhesive ribbon-shaped strings applied spaced apart and circularly around this outside convolution of-said ribbon-shaped film and holding this convolution and therefore said mattress and wrapper in said rolled-up configuration, said rolled and enveloped mattress being received in said'outer container.
  • the invention also includes an apparatus for packaging single mattresses.
  • Said apparatus includes: pressing and feeding means cantileverly projecting to reduce the thickness of said structure, the cover and the flexible wrapper being capable of fitting on said means, squeezing compression means to flatten said mattress together with its cover and its flexible wrapper; a rolling-up and pressing device including axially sliding and rotating mandrel means, a compressing and rolling cylinder elastically urged towards said mandrel; means for feeding and applying at least two ribbon-shaped adhesive strings around the mattress in rolled configuration on said mandrel; and means for axially moving said mandrel means to withdraw them from said mattress being in rolled configuration.
  • FIGs 1 and 2 a plant is shown for carrying out an intermittent working.
  • An equipment 21, per s6 known, presents a conveyor 23 on which the elastic mass M3 to be packaged may be laid down; the conveyor 23 inserts the mass M3 between two sets of arms 25,27 combined with conveyors and mounted on the equipment 21 so that they can be displaced parallel to themselves according to arrows fX to get closer between them and, in opposite direction, to be moved apart.
  • the mass M3, when it has been inserted between the arms 25 and 27, is pressed to some extent as indicated by MS to have its thickness reduced.
  • a cover C complete with padding and opened in correspondence of a mouth being provided with a continuous closure system L, like a so-called "zip" closure; this mouth and this closure L extend along one of the minor end fronts of the cover C and, in part, along the major sides as shown in Figure 4; the cover C comprises also foam padding with an inside film.
  • a continuous closure system L like a so-called "zip" closure; this mouth and this closure L extend along one of the minor end fronts of the cover C and, in part, along the major sides as shown in Figure 4; the cover C comprises also foam padding with an inside film.
  • a flexible and substantially air-tight wrapper P developed as an open sack, may be fit on the cover C this wrapper being realizable by thermoplastic film.
  • the elastic mass M5 is fed according to arrow f7 together with the cover C and the wrapper P by the advancement means combined with the arms 25,27 and also by the operator's intervention, until the assembly reaches the position M7 to rest upon a work plane 31 adjacent to the equipment 21. During the dwell on this work plane 31, the operator closes the cover C by means of the closure L.
  • the arms 25,27 may be provided with nozzles for the distribution of adhesive during the advancement of the assembly from position M5 to position H7 in order to make the inside surface of the cover C adhere on to' the mass M7.
  • a compression means 3 3 follows for flattening the mattress together with its cover C and the wrapper P.
  • This compression means includes a lower plane 35, preferably fixed, and an upper plane 37 displaceable according to the dual arrow f9 in order to lower and to press and flatten the mattress and also to be lifted therefrom.
  • the compression means 33 reduces the thickness of the mattress to the configuration M7, causing the air outlet from the wrapper P.
  • the upper plane 37 is raised, even if the wrapper P has not been closed, the mattress does not tend to rapidly expand, because the air is prevented from penetrating the wrapper P owing to its substantial impermeability: the air can only enter very slowly the wrapper P if this is not welded along the opening.
  • the compression means 33 may be also combined with a welding system 39,41 which, after the lowering of the upper plane 37 and the air outlet from the wrapper P, may be actuated to operate the welding.
  • a rolling-up and pressing device follows, generally indicated by 45 and better illustrated in Figures 6 to 11, in which the mattress, being in the configuration M7, is fed to be packaged in a more squeezed and rolled-up condition.
  • a compression means 133 which operates in a continuous way rather than in an intermittent way like the compression means 33.
  • the compression means comprises two seta of lower rollers 135 and of upper rollers 137 which are advantageously associated with respective belt means 139,141, and are disposed together with them so as to result gradually closer and closer in the direction of arrow f133 of the assembly advancement.
  • the mattress assembly, pushed out of the arms 25,27, may be slid on a short linking conveyor 143 and then delivered between the belt means 139,141, where this assembly is compressed during its advancement according to arrow f133.
  • the welding system may . be excluded, or a welding system 145,147 may be provided at the exit from the compression means 133.
  • the assembly being flattened into the configuration M7 by the compression means 133, can reach-the rolling-up and pressing device 45, where the mattress is packed in an even more squeezed and rolled condition.
  • a housing of said device comprises side frame 201 and supports 203 external to them for cylinder-piston systems 205; these systems serve to axially drive two - opposite stems 207 which form two semimandrels each capable of sliding according to arrows f207 to axially move away from each other up the outside of the two side frames and in the reverse direction to approach to each other in order to make u p a mandrel between the two side frames 2011 the facing ends of the two semi- mandrels are so shaped as to cooperate when they are coupled.
  • the two semi-mandrels are oapable of rotating around their respective axis.
  • Each semi-mandrel 207 is internally hollow to form a suction chamber through the holes 209 distributed along each semi-mandrel.
  • two jacks 211 are provided whose mobile parts 211A control the displacement of a shaft 213 for a compression and rolling cylinder 215; this cylinder 215 is located between the two side frames and is guided by means of supports 217 along guides 219 formed in the respective side frames.
  • the cylinder 215 may be approached towards and urged, according to arrow f215, against the mandrel formed by the two semi-mandrels 207; by a reverse drive, opposite to arrow f215, the cylinder 215 may be moved away from the mandrel.
  • the cylinder 215 is mostly capable of rotating idly, but it could be possibly driven to rotate in a direction opposite to that of the semi-mandrels 207.
  • a reservoir-spool 220 feeds a ribbon-shaped film 222, which is passed through guide means 224 located in the vicinity of the cylinder 215.
  • the end of the film 222 may be approached to the mandrel formed by the coupled semi-mandrels 207, when the cylinder is lifted ( Figure 7) and when a vacuum has been created inside the two semi-mandrels.
  • the end of the film 222 can thus be made to adhere by pneumatic suction against the mandrel.
  • This mandrel can be rotated according to arrow f207 just before the assembly - which has been pressed by the compression and flattening means 33 or 133 - is approached to it, and immediately after the film 222 has been pneumatically engaged against'the mandrel.
  • the assembly By approaching the cylinder 215, the assembly, being flattened by the means 33 or 133, is inserted between the cylinder 215 and the mandrel made up of the two coupled and rotating semi-mandrels 207 ( Figure 8) in order to start to be squeezed and rolled up ( Figure 9) together with the film 222 which results in contact with the cylinder 215.
  • the squeezed and flattened mattress is made to assume a rolled-up configuration while the air still present in the flattened mattress is progressively driven toward the open or welded end of the wrapper P; at the end of the rolling-up ( Figure 10 ), the wrapper P may be even torn off by the air if the latter does not find some exit opening.
  • the rolling-up proceeds with the film 222 only, to form at least one outside convolution 222A surrounding the rolled mattress ( Figure 11).
  • a mechanically or even manually operated cutting means cuts the film 222 and the end stretch of the film which has been rolled up together with the mattress is laid down on the outside convolution 222A.
  • three adhesive ribbon-shaped strings 230 are applied which are annularly disposed around the rolled mattress to stabilize the configuration of the outside convolution 222A of the ribbon-shaped film.
  • small machines 232 may be utilized of a type normally available on the market.
  • a single small machine can be utilized by the operator for the three consecutive operations for the application of the three ribbon-shaped strings 230, while the assembly continues to rotate on the mandrel.
  • a mobile equipment may also be provided carrying three machines 232 and which can approach them simultaneously to the rolled assembly rotating on the mandrel, for the simultaneous application of the three strings.
  • the rolling up may be also operated starting without the film 222 and by inserting it during the rolling up, or even without using the film and applying the ribbon-shaped strings on the wrapper P .
  • the mattress removed from the container may be released from the means 10 and stretched out, and the wrapper 3 may be opened in such a manner as to allow the entry of air and thus permit the re-expansion of the mattress which, more or less speedily, resumes the thickness intended for use.
  • Mattresses packed as indicated above may be stored for shipment and warehousing in a relatively economical manner, and are saleable individually also in the packed presentation, as a result of which the final user can conveniently carry the mattress purchased with the means at his own disposal, without difficulty or extra expense.
  • a mattress is obtained, which is able to re-expand in a very regular way, although being packed in a very squeezed configurat ion. This is at least in part, due to the gradual compression in subsequent times, and to the way in which the compressions are carried out.
  • the components are stabilized in their mutual position, owing both to the structure of the wrapper combined with a padding and to the possibility of gluing the mass M to the wrapper.
