Definitions

  • the invention refers to the logistics field and specifically to pallets used for the transport and storage of goods. Even more specifically, the invention is adapted to provide a plastic pallet and the related production system which adopts various printing technologies and control devices capable of guaranteeing temporal sequentiality in production.
  • a pallet is a flat structure on which goods are placed.
  • a pallet is the structural foundation of a load unit which allows handling and storage by means of tools such as forklifts, pallet trucks, and the like. Since its invention during the 20th century, the use of the pallet has gradually replaced older storage systems, such as wooden boxes and barrels. Although the most used material for pallets remains wood, there are also pallets made of plastic, metal or recycled material.
  • the pallet has by now become a full-fledged part of the logistics chain: even companies which manage bulky or non-standard sized goods, and which are therefore unable to use standard sized pallets, take steps to procure pallets with specific characteristics (both in size and material) in order to best complete the packaging of their materials.
  • An added value of palletizing goods is also that, after having wrapped the contents with transparent plastic films (now also of common use), further protection of the materials against damage caused by the movement of the materials by means of transport and bad weather can be obtained, as well as a greater guarantee against theft.
  • the most widespread pallets today include those made of plastic materials. The speed in their creation, the great workability, the recyclability and the mechanical characteristics make them the ideal elements for the transport of any kind of material.
  • the invention relates to a plastic pallet for use with fork lifting devices and which meets the requirements associated with food handling.
  • the pallet has a thermoplastic top consisting of two sheets which are partially spaced by rigid foam. There are steel reinforcing elements which run in an X-shaped configuration within the foam.
  • the plastic sheets each have a multiplicity of frustoconical depressions which provide passages for water and air. The plastic sheets are welded together at the depressions and their outer edges.
  • the invention relates to a method for reinforcing a plastic pallet having a plurality of relatively weak structural portions each comprising a portion of sheet metal with a plurality of vertical ribs extending therefrom.
  • the method includes fixing a plurality of sheet metal strips to the vertical ribs in the plurality of relatively weak structural portions, respectively, to form a plurality of substantially rectangular hollow vertical cross sections along the length of the weak structural portions to improve the rigidity thereof.
  • the invention refers to a pallet made so as to improve the visibility thereof and the identification of the lifting element insertion points.
  • the invention further includes the creation of a pallet also in modular shapes and with plastic materials of various kinds.
  • the present invention discloses a production system for producing plastic pallets made by joining two half-shells through vibrational, ultrasonic or hot plate welding techniques which provides a solution to the aforementioned technical problems.
  • a plastic pallet and the related production system are created.
  • the production system comprises a gas injection printing apparatus, a vibration welding machine, a hot plate welding machine and allows simultaneously producing pallets with different welding methods and geometries through the welding of two or more components each comprising an RFID tag.
  • the production system consists of other fundamental parts which are:
  • the database contains, for the RFID tag of a first component of a pallet, the identification codes of the RFID tags related to the other components to be welded to said first component.
  • control apparatus adapted to manage the printing cycles of said gas injection printing apparatus and to manage the transport of the printed components toward said vibration welding machine and/or said hot plate welding machine and to further manage the operation of these machines.
  • the control device receives data from the RFID readers to check the correct coupling between two components; when the RFID tags read by the RFID readers identify an incorrect correspondence between two or more components (i.e., they do not coincide with the associations between RFID tags present in the database), said vibration welding machine and/or said hot plate welding machine are stopped by said control device control which also sends a signal by means of an alert apparatus.
  • the control apparatus has a user interface which can be consulted via a portable device such as a smartphone, a tablet and/or the like (when the apparatus is equipped with a wireless communication unit) and/or via one or more displays included in the production system;
  • said alert apparatus sends signals of malfunctions or incorrect correspondence between two or more components through indicator lights, audio systems, notifications via mail, text messages and/or the like.
  • the system comprises an apparatus for robotic handling of said components and/or said pallets to completely automate the production process of said pallets.
  • the robotic handling apparatus comprises conveyor belts, robotic arms, robots moving on tracks and/or other programmable robotic elements to allow the production of pallets automatically which will not be described herein, as they are considered part of the art known to a person skilled in the art.
  • FIGURE 1 shows a general view of the production system 100 of plastic pallets 10
  • FIGURE 2 shows an exploded view of a plastic pallet 10 made with said production system 100.
  • the present invention describes a production system for producing plastic pallets 10 which comprises a gas injection molding apparatus 20, a vibration welding machine 30, a hot plate welding machine 40.
  • the gas injection printing apparatus 20 is used to make various components 11 of the pallets 10.
  • Gas injection printing means the printing process of a component made of plastic material through which a molten mass of material (plastic) is injected into a mold, and gas (preferably nitrogen) is subsequently injected into the molten mass.
  • the process begins with the injection of a quantity of plastic material in percentages preferably comprised within the range between 60% and 98% of the volume of the mold cavity.
  • gas preferably nitrogen
  • a bubble is formed which remains connected to the gas injection point, the pressure of which pushes the plastic material against the internal walls of the mold until it completely fills the mold cavity. The pressure on the gas is maintained until the piece extraction temperature is reached.
  • Vibration welding refers to a welding process between plastic components which includes the use of vibration.
  • the vibration of the parts produces friction which raises the temperature of the surfaces in contact until the materials fuse (weld) together.
  • the vibration welding method does not require an external heat input, as this comes from the dissipation of the energy produced by friction.
  • the increase in local temperature necessary for the process is obtained by rubbing, which fuses the appropriately prepared flaps of the two pieces to be welded.
  • a thrust pressure is applied to the piece subjected to movement so as to keep the parts to be joined in contact during the welding process.
  • Hot plate welding refers to the process in which a plate or blade is heated, thanks to the use of multiple resistors. Once brought to the correct temperature, the plate is placed between the two pieces to be welded. The hot plate is left in contact with the two pieces for the time necessary to melt the material of the pieces to be welded, after which the blade is removed and the two pieces are made to adhere which, also being at very high temperatures, are welded in the contact areas.
  • the production system 100 allows producing plastic pallets 10 by welding two or more components 11 , each of which comprises an RFID tag 101. Having an RFID tag 101 on each of the components 11 of a pallet 10 to be welded allows knowing right from the printing of individual components 11 which of them will be welded together. This allows having control throughout the production line and avoiding welding errors due to the incorrect coupling of two components 11 which were not intended to be welded together.
  • the RFID tags 101 also allow the RFID tags 101 to be maintained even during welding as the high temperatures for welding remain, both with said vibration welding machine 30 and with said hot plate welding machine 40, localized to the contact areas, and do not damage the RFID tags
  • the production system 100 of the present invention manages to overcome the technical problem of monitoring the assembly of the correct pieces during the production step and the technical problem linked to the creation of a weld between two components without removing RFID tags 101 (or in any case without using RFID tags resistant to high temperatures and thus more expensive).
  • a further RFID tag 101 is applied to the welded pallet 10 so as to identify the finished product.
  • the reading of even a single RFID tag 101 of a single component 11 of the already welded pallet 10 allows the identification of the finished product.
  • FIG. 1 a general view is shown of said production system 100 according to the present invention.
  • FIG. 1 as in the following description, the embodiment of the present invention currently considered the best is illustrated.
  • Said production system 100 allows the simultaneous production of plastic pallets 10 which have different geometries and different welding methods (customizable according to the needs of use of the pallets 10 themselves).
  • the production system 100 in addition to the apparatuses and machinery mentioned above, comprises:
  • the RFID tags 101 are associated so that the RFID tag 101 related to a component 11 is associated with all the other RFID tags 101 of other components 11 which must be welded together to create the same pallet 10;
  • control apparatus 130 adapted to manage the printing cycles (in terms of frequency, time, and type of components 11 to be printed) of said gas injection printing apparatus 20 and to manage the transport (in terms of transport speed and in terms of direction, i.e., whether to direct them towards one machine or another) of the printed components 11 toward said vibration welding machine 30 and/or said hot plate welding machine 40.
  • Said control apparatus 130 receives data from the RFID readers 120 to verify the correct coupling between two components 11 and when the RFID tags 101 read by the RFID readers 120 identify an incorrect correspondence between two or more components 11 (i.e., identify, by way of non-limiting or non-binding example, the presence at said vibration welding machine 30 and/or said hot plate welding machine 40 of a first component 11 related to a first pallet 10 and a second component 11 not related to said first pallet 10) said vibration welding machine 30 and/or said hot plate welding machine 40 are stopped by said control apparatus 130 which also sends a signal via an alert apparatus 140.
  • Said control apparatus 130 has a user interface 131 which can be consulted via a portable device such as a smartphone, a tablet (shown in FIG. 1) and/or the like;
  • said alert apparatus 140 which sends signals of malfunctions or incorrect correspondence between two or more components 11 through indicator lights, audio systems, notifications via mail, text messages and/or the like;
  • a sensor assembly station 150 in which one or more deformation sensors 151 are mounted on said pallet 10; said deformation sensors 151 adapted to measure the lowering due to bending of the component 11 in direct contact with the goods 1 (not shown in the Figure) deposited on the pallet 10.
  • Goods 1 is intended as any type of object which must be placed and/or transported with said pallet 10;
  • Said robotic handling apparatus 160 comprises means for automatic handling which are conveyor belts and programmable robotic arms to allow the production of the pallets 10 automatically.
  • Said robotic handling apparatus 160 comprises RFID readers 120 arranged on the means for automatically handling said components 11 and/or said pallets 10 so that, when the RFID readers 120 mounted at said vibration welding machine 30 and/or said hot plate welding machine 40 detect an incorrect correspondence between two or more components 11, said control apparatus 130 shows to the user, on the user interface 131 the position, in real time, of the correct components 11, on the robotic handling apparatus 160 whose RFID tag 101 has been read by one or more RFID readers 120 arranged on the automatic handling means.
  • the synergy between the technologies comprised in the production system 100 allows installing said deformation sensor 151 on the components 11 before their welding. This allows avoiding a considerable waste of time linked to the installation of the deformation sensor 151 on the finished pallet 10 and thus subsequently to the welding step of the components 11, as calibration operations would be necessary and the insertion of the sensor in the innermost parts of the pallet 10 would be difficult.
  • This last characteristic allows to overcome the technical problem linked to the need to know, on large robotic handling apparatuses 160 (in which there are a multitude of automatic handling means and a multitude of gas injection printing apparatuses 20 of vibration welding machines 30 and hot plate welding machines 40), the exact position of a component 11 which is being searched.
  • This characteristic also allows having an accurate indication of the position (along the robotic handling apparatus 160) of the correct components 11 to be welded together, when the RFID readers 120 arranged at said vibration welding machine 30 and hot plate welding machine 40, signal incorrect correspondences.
  • the control apparatus 130 sends an incorrect correspondence signal through the alert apparatus 140 and on said user interface 131 also showing the positions of the second component 11 related to the first pallet 10, and of the other components 11 related to the second pallet 10 on a graph which indicates them along the robotic handling apparatus 160.
  • the production system 100 shown in FIG. 1 also allows the creation of plastic pallets 10 even entirely composed of recycled plastic, but also pallets with metal reinforcing elements and others.
  • said user interface 131 can be consulted via one or more displays comprised in the production system 100.
  • FIG. 2 two bottom views of a plastic pallet 10 made with said production system 100 are shown. Said pallet 10 will be described with reference to FIGs. 1 and 2.
  • FIG. 2A shows an exploded bottom view of said pallet 10 in which it can be observed how it comprises numerous components 11 and how each of them has an RFID tag 101.
  • two components of a deformation sensor 151 can also be observed, which are the first upper part 157 (mounted on the upper component 11 in said sensor assembly station 150) and a second lower part 158 (mounted on the lower component 11, mounted in said sensor assembly station 150).
  • the second lower part 158 is large enough to fit inside the first upper part 157, which is slightly wider.
  • the sliding of the first upper part 157 on the second lower part 158 follows the lowering of the upper component 11 (as will be explained later in relation to FIG. 3).
  • the first upper part 157 and the second lower part 158 have a height such that they cannot be welded in said vibration welding machine 30 and said hot plate welding machine 40.
  • FIG. 2B shows a bottom view of said pallet 10 at the end of production, it can be observed that said pallet 10 has undercuts 12 (undercuts being intended as the protrusions of one or more components which in the pallet 10 are found at the bottom, in contact with the ground or with another support) being made by means of welding two or more components 11 using said vibration welding machine 30 and/or said hot plate welding machine 40.
  • Said undercuts 12 are such as to increase the contact surface with the ground (increase it with respect to the sole shape of the components 11 welded above), allowing a better distribution of loads since the surface pressure on the support elements is thereby distributed over a larger area, reducing the average tension and therefore deformations and the risk of punching.
  • the pallet 10 of FIG. 2B has the second lower part 158 inserted inside the first upper part 157, thus creating a deformation sensor 151.
  • FIG. 3 two enlarged views of said deformation sensor 151 are shown mounted on said plastic pallet 10 made with said production system 100. Said deformation sensor 151 will be described with reference to FIGs. 1, 2 and 3.
  • Said deformation sensor 151 functions analogically without the need for energy supply (from current, battery and/or other).
  • the dashed-line elements are hidden inside a covering shell of the deformation sensor 151 which, by way of non-limiting example, can be made of rubber, plastic or made of different materials so as to accommodate the deformations of the components 11 and/or to avoid external interference with the internal magnetic elements 152.
  • the shell comprises a first upper part 157 and a second lower part 158.
  • the second lower part 158 is large enough to fit inside the first upper part 157, which is slightly wider.
  • the deformation sensor 151 comprises two magnetic elements 152 which, as can be seen in FIG. 3 A, are installed on two components 11 of the pallet which are located one above the other, i.e., in the configuration in which the component 11 below rests on the ground or on another support, and the component 11 above is the one directly contact with the goods 1 (not shown in the Figure) positioned on the pallet 10.
  • FIG. 3B shows the deformed condition (with a graphically exaggerated lowering for the sole purpose of an easier reading of the Figure) of the component 11 above (that on which the goods 1 rest). In the deformed condition (FIG.
  • said magnetic elements 152 are brought closer to each other. Since said magnetic elements 152 are arranged with the positive poles ("+" in FIG. 3 A and 3B) facing each other, the first magnetic element 152 mounted on the deformed upper component 11 pushes the second magnetic element 152 mounted on the lower component 11, downwards (by magnetic repulsion).
  • the magnetic component 152 mounted on the component 11 below rests on a bar 155 which in turn is connected to a spring 154.
  • the lowering of the second magnetic component 152 causes the spring 154 to compress and the bar 155 to also lower.
  • a signaling element 153 is mounted on the bar 155, which in static conditions (FIG.
  • FIG. 3 A shows the indication “OK” through a rectangular opening 156 of the shell (present in both the first upper part 157 and in the second lower part 158) of the deformation sensor 151, while when the limit deformation is reached (FIG. 3B), which is defined in the design step based on the geometry of the pallet 10 and the resistance of the materials with which it is composed, through the rectangular opening 156 the signaling element 153 shows a symbol (“X” in FIG. 3B) indicative of having reached a deformation state which compromises the integrity and load-bearing capacity of the pallet 10.
