Definitions

  • the present invention concerns a device for packing a mattress filling and a procedure for packing a mattress filling.
  • the invention also refers to mattress fillings that are compressed in order to be compacted and inserted into a packing container.
  • mattress fillings are currently made of latex or polyurethane and, at times, features through holes to make them lighter.
  • Said mattress fillings are often packed in vacuum-packaging for successive sale.
  • a wrapping usually made of flexible plastic material.
  • the wrapping is then connected to a vacuum pump which extracts the air from the inside of the wrapping and produces a package with compact height or thickness, maintaining the filling length of approximately 2 metres, even if rolled or similar.
  • the aim of this invention is therefore to eliminate the above technical problems, producing a simple and inexpensive device and procedure for packing mattress fillings.
  • Another aim of the invention is to produce a packing device and procedure that permit the production of reliable safe packaging, although arranged in limited spaces.
  • the present invention also refers to a procedure for packing mattress fillings according to claim 8.
  • the advantage of the device according to the present invention is that it permits the production of packages with limited bulk which are easy to transport and store. On the whole, therefore, these packages are easy to handle.
  • a packing device 11 is shown for packing or wrapping a mattress filling 12.
  • the filling 12 can be made of polyurethane foam or latex of any density, moulded or cut in the required dimensions.
  • the filling 12 features through holes 14 which, in addition to making it lighter, increase its compressibility.
  • the holes 14 are perpendicular with respect to the two largest walls of the filling 12 and can also have different dimensions.
  • the holes 14 can have different dimensions in specific areas of the filling 12, according to requirements. For example they can be larger at the two ends of the filling 12 designed to support the head and feet of a user and smaller in the central area of the filling 12, as compared with the above mentioned end holes.
  • the holes 14 are made using a punching machine 16.
  • the machine 16 comprises a rectangular fixed plate 18 provided with a lead screw 20 on each of its corners.
  • the lead screw 20 is coupled with a threaded pin 22 from which a cylindrical tang 24 protrudes; a thrust bearing 26 which supports a moving plate 28 locates on the tang 24.
  • the moving plate 28 is also rectangular and features four through holes 13 on its corners, in which the threaded tangs 24 fit without engaging.
  • a sprocket 30 is fitted on each tang 24, on the opposite side with respect to the bearings 26.
  • the four sprockets 30 engage with a chain 32 which can be driven by means of an actuator not shown.
  • the moving plate 28 also features four additional through holes 15 again to be found on its corners.
  • the plate 28 carries integrally an enlarged element 36 which acts as a guide for a column 34.
  • a sliding guide column 34 shaped and fastened to the fixed plate 18, is inserted in each of the through holes 15 and tubular elements 36.
  • the punching machine 16 is also provided with a mobile unit 38 with a number of punches 40.
  • the punches 40 can be all the same size or sized differently.
  • the punches 40 positioned at the longitudinal ends of the machine 16 can have larger dimensions (i.e. diameter) while those corresponding to the central part will have smaller dimensions (i.e. diameter).
  • the mobile unit 38 can be driven by means of an actuator, not shown for the sake of simplicity.
  • the ends of the punches 40 are inserted in guide through holes 17 made on the plate 28. Aligned with the holes 17, the fixed plate 18 is provided with profiled through seats 19 in each of which a bush 42 is inserted and locked.
  • the bushes 42 feature a protruding edge which abuts against a shoulder 21 of the same seat 19.
  • the punching machine 16 makes the through holes 14 in the mattress filling 12 as described below.
  • the filling 12 is inserted between the fixed plate 18 and the moving plate 28.
  • the moving plate 28 is positioned against the filling 12. The moving plate 28 moves down, compressing the filling as required.
  • the mobile unit 38 is activated as indicated by the arrow F in figure 6, so that the punches 40 pierce the filling 12 and locate in the bushes 42 of the fixed plate 18.
  • the filling 12 in which the through holes 14 have been made can then be taken out by resetting first the mobile unit 38 and then the moving plate 28 to their initial position.
  • the fixed plate 18, together with the moving plate 28, the mobile unit 38 and related punches 40 are interchangeable with similar components of different sizes.
  • the filling 12 is packed very simply and quickly, using the device 11.
  • the device 11 consists of a box-type L-shaped body (52) with prismatic section comprising successive compression chamber 54 and expulsion chamber 56 positioned at right angles to each other.
  • the body 52 features three apertures 58, 60 and 62.
  • a sliding piston 64 can be inserted inside the body 52.
  • an extraction piston 66 can be inserted inside body 52; said aperture 60 faces an outlet 62 positioned at the other end of the body 52.
  • the compression chamber 54 is defined by a side portion of the body 52, by the piston 58 and the piston 66 which closes the aperture 60.
  • the chamber 54 is also defined and separated from the chamber 56 by a removable guillotine-type intermediate partition 68.
  • the expulsion chamber 56 is located in a part of the body 52 successive and opposite to the one provided with aperture 58.
  • the chamber 56 is defined not only by a different lateral part of the body 52 (from the part that defines the chamber 54), but also by the guillotine partition 68.
  • At one end of the chamber 56 is the outlet 62 from which the filling 12 is expelled after being compacted.
  • Both the piston 64 and piston 66 are moved by means of drive systems not shown; these are positioned in line with the pistons or at the side of the body 52.
  • a container 70 which is to contain the filling 12 can be fitted on the part of the body 52 forming the expulsion chamber 56.
  • the container 70 is rigid and is usually parallelepipedal with rounded corners.
  • the container 70 is made to measure in cardboard or rigid plastic.
  • the present invention also concerns a procedure for packing a mattress filling.
  • the filling 12 to be packed is placed inside the compression chamber 54 of the L-shaped body 52, with the aperture 60 closed by the piston 66 and the guillotine partition 68 lowered to form the side of the chamber 54.
  • the procedure of the invention provides for an initial compression phase performed by the piston 64 which compresses the filling 12 inside the chamber 54.
  • the piston 64 moves until the compression chamber 54 size is similar to the transverse size of chamber 56.
  • the piston 66 is translated and pushes the already compressed filling 12 towards the chamber 56.
  • the piston 66 pushes the filling 12 so that it passes firstly into chamber 56, then comes out of chamber 56 via the outlet 62 and is inserted in the container.
  • the machine in question can implement the procedure described using many different types of mattress filling.
  • the fillings can be provided with holes 14 or be without holes, without this affecting correct operation of the device and the procedure.
  • the filling 12, for single mattresses for example, with one standard size, and packed as described, can be inserted in covers of different sizes according to requirements to obtain ready-to-use mattresses of different sizes.
  • one single standard size mattress corresponding to the maximum size required, compacted as described, can be inserted very easily into a cover with the desired and required dimensions.
  • the device and procedure for packing a mattress filling are particularly advantageous as they are simple and permit compact packing which is easy to transport, to store and, above all, to handle.
  • the fillings, packed as described, can also be used inserted in covers of different sizes. This makes them very flexible and a very attractive proposition from the commercial point of view.
