Definitions

  • This invention is intended for the sector of production of packaging made in rigid, non-folding material, commonly called crates, featuring high resistance to vertical compression.
  • This kind of packaging is suitable for any kind of use, particularly for containing, transporting, storing and distributing all kinds of products, especially foodstuffs and/or fruits and vegetables, which, in view of their fragility, need adequate protection, both during storage and during transportation from points of production to destinations, including in refrigerated environments.
  • the commonly known packaging include a base (mainly made out of various elements stapled together with metal wire), four corner posts rising from the corners of the base and four sides, fixed to the posts, generally with the use of metal wire.
  • the base panel, posts and sides are generally made from rigid material of a natural or ecological type, such as wood, MDF, plywood or compound material.
  • Making a crate like this involves cutting various panels, which have to form the base and the four sides of the crate, and these panels are fixed to the posts by stapling with metal wire facing to the inside of the crate.
  • the metal wire for the stapling is exposed to humidity and can become rusty. Obviously, if the rusty metal wire comes into contact with foodstuffs contained inside the crate, this will no longer meet satisfactory standards of hygiene and health.
  • packaging obtained starting from a flat panel, building up in volume.
  • this type of packaging is made from plastic and/or cardboard material, which is not natural or ecological and requires special treatment with chemical substances if used with foodstuffs, but also does not resist well to compression and humidity. Furthermore, to obtain the packaging, a lot of material from the original panel is wasted.
  • a creaser is used to fold the cardboard.
  • the cardboard is squeezed along a line (representing the fold line) or is perforated in places.
  • a film has to be glued to the panel and a channel cut into the panel with a cutting tool.
  • US5673848A describes a crate made in cardboard.
  • a film can be applied to the cardboard to protect against humidity. Such a film does not function as a hinge.
  • the cardboard does not have a stopped channel cut with a milling machine, by removing material.
  • the cardboard has a crease, to allow the fold.
  • the crate has corners made by folding the cardboard.
  • the machinery does not have an automatic stapler, because the cardboard is glued.
  • FR1181969 and FR2642398 describe a packaging made from a sheet of cardboard, with wooden corners stapled or glued to the cardboard.
  • these documents do not describe any equipment, nor any method for making the packaging.
  • sheets of other foldable materials plastic or light metal materials
  • non-foldable materials such as wood, fibre wood, MDF, plywood or similar materials is excluded. Therefore the equipment does not require a cutting tool to form fold lines.
  • the equipment does not require a forming machine or a stapling machine.
  • FR2985504 describes a cardboard box with corners made by folding and gluing the cardboard. No stapling is described. Also, in the fold at the corner, the corner fixing flap remains on the outside. Therefore, if stapling were used, the metal wire of the stapling would be inside the box and would be in contact with the contents of the box, with consequent hygiene/health problems. However, the equipment does not require cutting tools or forming or stapling machines.
  • DE2450702A1 describes cardboard packaging made from a cut-out, which folds along creases or perforated stretches. On the sheet of cardboard there are no channels on the fold lines with milling machines involving removal of material. This type of packaging does not require any stapling.
  • EP2228206A1 describes equipment for making boxes from corrugated cardboard. The process starts from a large sheet, from which several boxes are made, passing through the following units:
  • the fold lines are made by the creaser (squeezing the cardboard with creasing rollers) in unit (C).
  • the slotter makes slots, which are actually cuts separating the various flaps of the cardboard making up the box.
  • the cuts are made with a blade and counter blade, which rotate during cutting at a peripheral speed similar to that of the movement of the sheet of cardboard.
  • the creaser rollers also rotate at a speed similar to that of the sheet of cardboard.
  • the packaging does not require posts and the plant does not require milling, forming or stapling machines.
  • EP2366633A1 in the name of this applicant, describes a forming machine and packaging made with that forming machine.
  • the forming machine enables a completely automatic method for making packaging starting from a flat sheet.
  • the said forming machine is not suitable for making crate-type packaging with corner posts on the crate to give the crate rigidity.
  • the purpose of this invention is to eliminate the inconveniences of existing techniques and provide crate-type packaging, particularly for containing and transporting foodstuffs and/or fruits and vegetables, which have the advantages typical of packaging made from rigid, non-flexible materials, i.e. robustness, stability and hygiene.
  • Another purpose for this invention is to provide plant and an industrial production process for making crate-type packaging that is practical, economical, versatile and completely automatic.
  • the plant is used for production of crate-type packaging starting from a panel, comprising a sheet of rigid, non-flexible material and a film attached to the sheet.
  • the plant includes:
  • the crate obtained with the plant and method according to the invention is particularly suitable for containing all kinds of products, especially foodstuffs and/or fruits and vegetables.
  • the crate made with the plant and method according to the invention features the following advantages compared to traditional packaging made starting from a single panel:
  • the process and the plant, according to the invention are particularly simple and cheap, in that they do not require special equipment, high energy consumption or specialised labour. Furthermore, the process and the plant, according to the invention, enable the packaging to be made from a panel of rigid, non-foldable material (wood, fibre wood, plywood, M.D.F. compound material, etc.), which is particularly resistant to compression from vertically stacked loads.
  • Crate packaging is especially suitable and cheap for containing all kinds of products, especially foodstuffs and/or fruits and vegetables, which, given that they are fragile, need adequate protection, both in considerable storage in refrigerators and during transport from production sites to those of destination.
  • the crate packaging may be replaced in flat form, in order to save space, for recycling when possible or for sending for disposal.
  • the plant includes:
  • the plant may include a cutting saw and feeder (D), used to cut battens to form corner posts (posts with a triangular section), which are then fed into the stapling machine (E).
  • D cutting saw and feeder
  • E stapling machine
  • the plant may also include a forming and stapling machine (F), used to form a crate from a flat panel and to staple the sides of the crate to the corner posts.
  • F forming and stapling machine
  • a crate (200) is shown, as obtained with plant according to the invention.
  • the crate (200) comprises a base (3), four corner posts (6), which rise from the corners of the base, two longitudinal sides (4) and two transversal sides (5), fixed to the corner posts (6).
  • the crate (200) is obtained starting from a panel (1).
  • the panel (1) has a substantially rectangular or square shape and features two longitudinal edges (10) and two transversal edges (11).
  • the panel (1) comprises a sheet (2) in rigid non-folding material, such as, for example, wood, fibre wood, plywood, MDF, compound material and the like.
  • a film (20) is attached to the sheet (2), by gluing, for example.
  • the film (20) is positioned on a face of the sheet that is to be turned towards the outside of the crate.
  • the dimensions of the panel (1) are substantially the same as the proportions of the base (3) and the sides (4, 5) of the crate.
  • the desired height of the crate (200) is determined by the length of the corner posts (6).
  • the film (20) may be glued to the sheet (2), using any known method (not shown in Fig. 1 ), such as, for example, a sealer, an automatic coater or a laminator.
  • This film (20) may be of any flexible material, such as, for example paper, card, plastic film, duct tape and the like.
  • the film (20) may be transparent, non-transparent and/or printed with a desired print.
  • the film (20) may be transparent, to show the printed external face of the sheet (2).
  • the film (20) may be printed before or after application to the sheet (2), in order to save on the treatment of the sheet surfaces (2).
  • the first stage of the process involves cutting the panel (1), with the shearing machine (A).
  • the shearing machine (A) is of a known type and may be, for example, a shearing or punching machine, flat press or rotary press fitted with spikes to make through cuts and openings (holes and eyelets) in the panel (1), or a milling machine or laser cutter and the like may be used.
  • a panel (1 a) exits from the shearing machine (A) with a number of through openings, which cut through the entire thickness of the panel, in other words the through openings pass completely through the sheet (2) of rigid material and the film (20).
  • These numerous through openings include openings for transpiration (12) and four corner openings (13).
  • the transpiration openings (12) are circular and/or oblong eyelet shaped and are cut into a central area of the panel (1 a).
  • the transpiration openings (12) enable transpiration of the product contained in the crate (200).
  • the corner openings (13) are hexagonal in shape, with a first end (13a) pointing towards the longitudinal edge (10) of the panel and a second end (13b) pointing towards the transverse edge (11) of the panel.
  • the corner opening (13) has a through axis for its ends (13a, 13b) forming 45° angles with the longitudinal and transverse edges (10, 11) of the panel.
  • the panel (1 a) exits from the shearing machine (A) and passes to the first milling machine (B), which executes on the panel (1 a) longitudinal cuts, parallel to the longitudinal edges (10) of the panel.
  • a panel (1b) is shown exiting from the first milling machine (B).
  • the longitudinal cuts follow longitudinal through lines for the first end (13a) of the corner openings (13).
  • Each longitudinal cut creates longitudinal through openings (14) which extend from the transverse edge (11) of the panel to the first end (13a) of the corner openings (13) and longitudinal channels (15) which extend between the two ends (13a) of two corner openings.
  • the longitudinal channels (15) are obtained as carvings only on the sheet (2) of rigid material and not on the film (20).
  • the longitudinal channels (15) may be interrupted by transpiration openings (12).
  • the longitudinal channels (15) define folding lines, for folding the longitudinal sides (4) of the crate.
  • the panel (1 b) exits from the first milling machine (B), and passes to the second milling machine (C) which executes on the panel (1 b) transverse cuts, parallel to the transverse edges (11) of the panel.
  • a panel (1c) is shown exiting from the second milling machine (C).
  • transverse cuts follow transverse through lines for the second end (13b) of the corner openings (13).
  • Each transverse cut creates transverse through openings which extend from the longitudinal edge (10) of the panel to the second end (13b) of the corner openings (13) and transverse channels (16) which extend between the second ends (13b) of two corner openings.
  • corner portions of the panel (1 c) are removed from the panel, so that the longitudinal sides (4) and the transverse sides (5) of the crate are defined.
  • the portions of the longitudinal sides (4) are separated from the portions of the transverse sides (5) by windows (17) created from the corner openings (13) to the corners of the portion of the base (3).
  • the transverse channels (16) are obtained as carvings only on the sheet (2) of rigid material and not on the film (20).
  • the transverse channels (16) define folding lines, for folding the transverse sides (5) of the crate.
  • a shearing or punching machine requires very high power and therefore high energy consumption compared to a milling machine.
  • the first milling machine (B) comprises pushers (70) fitted on chains (71) supported by guides (72).
  • the panel (1 a) is positioned on the chains (71).
  • the pushers (70) push a transverse edge (11) of the panel.
  • the panel (1 a) is positioned on the chains (71) in such a way that the longitudinal edges (10) of the panel are parallel to the direction of motion of the panel and the sheet (2) of rigid material is facing upwards.
  • the first milling machine (B) comprises a first cutting station (S1) to make a through cut to create the longitudinal through openings (14) and a second cutting station (S2) to make an incision (stopped) in the sheet (2) of rigid material to create the longitudinal channels (15).
