    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] The present invention presents, in a first aspect, an apparatus for the application of a decontaminating product on formed and empty trays, suitable for installation at the exit of a tray-forming machine from flat die-cut plates. The invention provides in a second aspect an installation for the application of a decontaminating product on formed and empty trays.
    [0007]
    [0008] Throughout this description, the material of said trays and flat die sheets can be corrugated cardboard, corrugated plastic, compact cardboard, compact plastic sheet, and the like.
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] Document ES2393388B1 describes a method for the industrial manufacture of a corrugated cardboard tray with a sheet of polylactic acid comprising the steps of manufacturing the polylactic acid film with antimicrobial agents according to established industrial procedures, manufacturing micro-corrugated cardboard sheets, applying the Polylactic acid film obtained in the previous step on the micro-corrugated cardboard sheet according to established industrial procedures, die cut (cut) the plates with the polylactic acid film already applied to allow its folding for the formation of the corresponding trays with application of necessary adhesive between the sides and the bottom of the tray, and fold the die-cut iron to form a tray. Therefore, the application of the contaminating product occurs on the corrugated cardboard plate before it is punched, and therefore, before the formation of the tray.
    [0013]
    [0014] A drawback of the method of document ES2393388B1 is that the application of the decontaminant product occurs on the corrugated cardboard plate. This causes that the time that elapses between the production of the cardboard plate with the decontaminant product and the packaging of the food in the already formed cardboard tray is undetermined and can be variable, so the effect of the decontaminant product will be greater or less depending on a respective greater or lesser elapsed time. In those occasions that spend a greater time, the food contained in the tray can be contaminated with microbes and / or unwanted bacteria.
    [0015] Another drawback due to the application of the decontaminating product on the plate before being stamped is that, given a change in the specifications of the cardboard order, for example a change in the quality of the cardboard or a change of food to be contained, the cardboard produced already has the decontaminating product applied in a suitable dose for a specific food and specific cardboard, and therefore said cardboard cannot be reused directly as conventional remaining cardboard, but the decontaminant product must be eliminated. Such additional operations increase manufacturing costs in the cardboard plant of the corrugated cardboard manufacturer.
    [0016]
    [0017] Document ES2534529B1 describes a method for surface decontamination of solid foods packaged using essential oils as a decontaminating product. It comprises the stages of evaporating the essential oils in a vacuum vessel and the application of the vapors of the essential oils on the solid packed feed located in a vacuum enclosure. Vacuum conditions accelerate product evaporation. Thus, the application of the contaminating product occurs once the food is contained in the container or tray.
    [0018]
    [0019] Document ES2534529B1 describes an installation comprising tapes that feed the containers filled with food to be decontaminated. The installation comprises an element that pushes the full containers into a tunnel. The installation comprises an entrance gate that opens and allows the containers to enter a vacuum enclosure. The vacuum vessel is housed inside the tunnel. The installation comprises an exit gate. When the input gate and the output compound are closed, the vacuum enclosure is sealed. The vapors are then applied to the food placed in the open containers. Vapors from the contaminating product flow from the vacuum vessel to the sealed vacuum enclosure. After the application of vapors, the tunnel belt stops, the gate closes the exit gate and the entrance gate opens. Alternatively, the two gates open. In any case, a new load of containers full of food is allowed in the enclosure. The tunnel has several cycles of advance and stop, where the full containers remain in this tunnel. At the exit of the tunnel there are some exit belts that transport the containers to a heat sealing machine.
    [0020]
    [0021] A drawback of the method and installation of document ES2534529B1 is that the cost of manufacturing and implementing the installation required for said method is relatively high. The installation requires in an embodiment of a multi-stage tunnel and at least two tapes whose dimensions in plan are relatively large. In another embodiment the Vaporization is carried out in chambers specially conditioned for this, which again increases manufacturing and implementation costs. In any case, these embodiments occupy relatively large plant dimensions, and in addition the container is full of the product to be contained.
    [0022]
    [0023] In the agri-food industry, the companies of packaged products have packaging warehouses that are divided into two totally differentiated areas: storage area and packaging area.
    [0024]
    [0025] In the storage area, one or more tray-forming machines such as those described in documents US2798416A, US3978774A, ES235835U, ES255122U, US4581005A, ES2593823B1, and ES1207138U form trays, generally made of corrugated cardboard, from flat, die-cut sheets. A conveyor at the exit of each tray forming machine feeds said formed trays to the packaging zone.
    [0026]
    [0027] In the packaging area, the food, for example fruits or vegetables are introduced into the trays formed, conventionally manually. Depending on the season, the same fruit and vegetable packaging company changes from one packaged food to another, which modifies the stockings of the formed tray.
    [0028]
    [0029] After packaging, trays full of food are stacked on top of each other on a pallet. The pallet comprises a plurality of stacked tray stacks. Subsequently, said trays full of food stacked on pallets are introduced into chambers, which may or may not be equipped with a temperature controlled device.
    [0030]
    [0031] Alternatively, the packaging companies do not form the trays from the plates punched out in the packaging warehouse, but instead buy the already formed trays from the so-called "assembly centers", that is, warehouses where said trays are formed by means of the said tray forming machines Generally, at the exit of the tray forming machine there is a tray stacking machine formed as described in document ES2343771B1 The stacked and empty stacked trays are arranged on pallets, generally manually, ready for Your delivery to the customer.
    [0032] WO2017089292A1 describes an antimicrobial solution implemented inside the package just before the fruit and vegetable product is inserted into said container. It is also explained that said antimicrobial solution can be distributed in several ways; It can be using a roller, a spray, or a brush. Preferably the Distribution is done by means of a spray on a porous surface such as corrugated cardboard. The application of the antimicrobial solution is performed on the empty container. The application can take place at different points of the distribution chain of corrugated cardboard packaging: from the production of the flat die plate to the tray mounted immediately before the packaging of the food product.
    [0033]
    [0034] WO2017089292A1 further describes an example in the case of corrugated cardboard packaging. The corrugated cardboard container arrives in the form of a flat sheet die cut from the corrugated cardboard manufacturer to the manufacturer / packer of fruit and vegetable products. The manufacturer / packer of fruit and vegetable products loads the flat plates punched in a tray-forming machine, which through a mold, and a male that descends on the flat plate punched with glue points supplied by the machine, forms the tray. The tray leaves the mold and passes through a tape with a tunnel in which the antimicrobial solution is sprayed, spraying it. Next, the box is sent to the packaging area.
    [0035]
    [0036] None of the documents define an apparatus or machine for the application of decontaminating products on formed and empty trays. That is, on trays that do not contain the fruit and vegetable product arranged inside. It would be desirable for said apparatus to adapt to the needs of the fruit and vegetable packaging sector, providing adequate production speed with a low manufacturing and implementation cost. On the other hand, it would be convenient to have an apparatus adaptable to the wide variety of formed tray stockings that are packaged in the same packaging ship. Also, it would be desirable for said apparatus to have reduced plant dimensions, that is, to be a compact machine.
    [0037]

Said inner panels comprise the base (11) and the inner walls (12) of the tray (B). In the example, the tray (B) comprises four inner walls (12) facing two to two.
    [0136]
    [0137] The apparatus (50) of this first embodiment includes a tray selection station (20), which selects a tray (B) from a row of trays (B) aligned according to the direction of travel (A) of the conveyor (1) .
    [0138]
    [0139] The tray selection station (20) comprises a first detector (F1) that sends a binary signal in use indicating the detection or non-detection of a tray (B).
    [0140]
    [0141] Also, the tray selection station (20) comprises a first active stop (3) movable between the retracted position of Figs. 8 and 9 which enables the passage of the tray (B), and the retention position of Figs. 6, 7, 10 where it prevents the passage of the tray (B).
    [0142] Likewise, the tray selection station (20) comprises a second detector (F2), located before the first detector (F1) according to the direction of travel (A) of the conveyor (1). The second detector (F2) sends a binary signal in use indicating the detection or non-detection of a tray (B).
    [0143] In addition, the tray selection station (20) includes a second active stop (4) located before the first stop (3) according to the direction of travel (A) of the conveyor (1). The second stop (4) is movable between the retracted position of Figs. 6, 9 and 10 which enables the passage of the tray (B), and the retention position of Figs. 7 and 8 where it prevents the passage of the tray (B);
    [0144]
    [0145] Likewise, the tray selection station (20) comprises a third detector (F3) located before the second detector (F2) according to the direction of travel (A) of the conveyor (1). The third detector (F3) sends a binary signal in use indicating the detection or non-detection of a tray (B).
    [0146]
    [0147] Each of said detectors (F1, F2, F3) is materialized in a photocell.
    [0148]
    [0149] Also, the tray selection station (20) includes an active third stop (5) located before the second stop (4) according to the direction of travel (A) of the conveyor (1). The third stop (5) is movable between the retracted position of Figs. 6 and 7 which enables the passage of the tray (B), and the retention position of Figs. 8 to 10 where it prevents the passage of the tray (B).
    [0150]
    [0151] The operation of the tray selection station (20) for the first aspect of the invention is described below.
    [0152]
    [0153] The tray forming machine (90) of Figs. 3 and 4 form trays (B) from flat plates automatically die cut, which produces a row of trays (B) formed and empty arranged on the conveyor (1).
    [0154]
    [0155] The complete sequence of the tray selection station (20) can be carried out with a movable transport element (24) of the conveyor (1) moving at all times. The transport element (24) is embodied in a transport band (24). The movable transport element (24) according to the direction of travel (A) by a motor member of the conveyor (1), materialized in the example by a drum motor, that is, a motor integrated in a rotation shaft.
    [0156]
    [0157] In Fig. 6, the tray forming machine (90) is forming trays (B) and the first detector (F1) detects a tray (B). Then, the first stop (3) moves to the retention position where it prevents the passage of the tray (B).
    [0158]
    [0159] Following in Fig. 7, the second detector (F2) has sent an indicative signal indicating the detection of another tray (B), and since the first detector (F1) detects a tray (B), the second stops (4) they move to the retention position where it prevents the passage of another tray (B) located immediately behind the tray retained by the first stops (3). In Fig. 7 the third stops (5) are in the retracted position. In addition, the four detector (F4) located before the third detector (F3) according to the direction of travel (A) of the conveyor (1), has sent a binary signal indicating the detection of a tray (B) and has stopped the forming machine of trays (90) since it has detected a tray (B) stopped on the conveyor (1).
    [0160]
    [0161] In Figs. 6 and 7 the first stops (3) are in the holding position and the applicator (6) can apply the decontaminant product on one or more inner panels (11, 12) of a tray (B) formed and empty. In Figs. 6 to 10 the position of the tunnel support (2) is indicated briefly. Fig. 5 shows in detail the elements of the applicator device (6) and the tunnel support (2).
    [0162]
    [0163] Continuing in Fig. 8, after applying the decontaminating product, the first stops (3) go to the retracted position, while the second and third stops (4, 5) are in the holding position. This allows the tray (B) with the decontaminant product applied to its base (11) to advance, and the rest of the trays (B) in the row are retained.
    [0164] Subsequently, Fig. 9 shows that the second stops (4) go to the retracted position, whereby, the tray (B) without decontaminating product applied to its base (11) arranged in the second stops (4) will move according to the direction of advance (A). Fig. 10 shows that said tray (B) moves up to the height of the first stops (3), where the first detector (F1) detects the tray (B) and moves the first stops to the holding position with which the tray (B) is retained.
    [0165]
    [0166] In Fig. 10, the second stops (4) are in the open position whereby the tray (B) of the row of trays (B) located at the height of the third stops (5) will move to the height of the second stops (4), where it will be retained. It should be noted that in Fig. 10, the fourth detector (F4) does not detect tray (B) and sends a binary signal to the tray-forming machine (90) to start the tray formation (B) again.
    [0167]
    [0168] Figs. 1 and 2 show that the apparatus (50) of this first embodiment further comprises said conveyor (1). The conveyor (1) comprises a chassis on which two transport guides (19) support, each located on one side of a transport band (24) movable by a motor member. In Figs. 1 and 3 it is observed that the end of the conveyor disposed at the exit of the tray-forming machine (90) is provided with receiving members (22), which center the tray when it is ejected from the tray-forming machine (90 ).
    [0169] Figs. 1, 2 and 5 to 10 show that the tray selection station (20) further comprises a linear guiding device embodied in an omega-type guide (17) supported on the conveyor (1). The linear guidance device is aligned with the forward direction (A) of the conveyor (1).
