DESCRIPTION

DEVICE FOR FRUIT FIXTURING MACHINE

TECHNICAL AMBITION

The present invention relates to a device for a fruit-wrapping machine of general application in the agricultural machinery industry, and in particular as the means of suctioning a layer of fruit, intended to be used in fruit packing machines or packers, especially of cltricas fruits.

For this purpose, the device has a high air aspiration flow, created by a turbine driven by a motor, which is attached to a flexible conduit of a certain length and of an adequate diameter through which the great volume of air drawn by the turbine flows. and whose conduit is provided with a spring means that allows the elongation and contraction of the conduit, according to the work cycles of the packing machine.

Said flexible conduit is associated by its lower end, to a hollow bell that absorbs the flow of air from the outside and in whose base it incorporates a grid with grooves, which as a template, determines the aspiration of a load of fruits of the same caliber and that constitutes the layer of fruit that is transferred to a box for transport and trade.

All this is arranged so that, when the turbine sucks a large volume of air through the duct and through the absorption hood, a layer of fruit is raised and retained by the template, which partially closes the base of the hood, The object is then to transfer the retained fruit layer to the inside of a box, where they are discharged when the turbine stops sucking.

To make this retention of the fruit more effective, at the base of the bell an elastic curtain of contention of the fruit has been arranged, which contours the embouchure of the bell, and which determines with the bell the shape of a cajeado, whose bottom It is the template itself, while the side walls are formed by sections of the elastic curtain.

This determines that the turbine, when sucking a large volume of air, through the template of the absorption hood, the elastic walls of the curtain adhere to the extreme fruits of the load, in order to retain them until they fit into the box , which avoids the involuntary melting of the fruit during its transfer to the box.

BACKGROUND OF THE INVENTION

In the current state of the art systems for the suction of fresh fruit are already known, in order to automate their packing or packaging in boxes for their trade and transport.

In all the known systems suction cups are used as suction means, which can work unitarily carrying a single fruit to the box to form a layer, or suction cup carriers are used, each of which sucks a fruit and whose number of suckers and position of the same coincide with the number of fruits of a layer, which allows to speed up the automatic work of packaging or packaging the fruits in a box.

This system of cup holders, each of which vacuum sucks a single fruit and are arranged on a support in the right position to form a layer of fruit, can be checked in the Spanish utility models with the publication number ES- 1035479_U by " Engaging machine for horticultural products" of date of application 7/31/96, publication number of model ES-1035648_U by "Fruit packing machine inside boxes" of date of application 12/11/96, number of publication of model ES-1036450_U by "Fruit packing machine" of application date 05/16/97, publication number of model ES-1041080_U by "Fruit positioning device" of date of application 09/14/98, and publication number of model ES-1078598_U by " Encajadora " of application date 01/24/2013.

Likewise, the system of suckers, each of which sucks a fruit and are distributed on a support in the position of a fruit layer, can also be checked in the invention patents with the publication number ES-2142199_B1 by "Enveloping machine for ellipsoidal objects" of date of application 07/06/1996, publication number patent ES-2142211_A1 for "Fruit packing machine inside boxes" of date of application 12/11/1996, publication number patent ES-212186524_B1 for "Machine of fitting fruits" of date of request 07/02/2001, and number of publication of the patent ES-2277731_B1 by "Machine for the introduction of spheroidal articles in a multitude of container models" of the date of application 03/29/2005.

This suction system with suction cups has the disadvantage that the suction cup has a circular surface in contact with the very small fruit, which can cause the fruit in its transfer to the box to fall from the suction cup due to the weight, due to the corrugation of its skin, or to an irregular disposition of the fruit or also by the existence of stems with leaves in the pieces of fruit.

Likewise, when the vacuum is made in the whole cup holder assembly at the same time to suck each one of them a fruit, the suction power of the air in one of the suction cups can be lowered by a seal in the air outlet of the cup holder. , which causes the loss of the fruit by requiring a greater suction in the suction cup.

Finally, note that cup holders that are properly distributed on its support to form a layer of fruit of the same size to fit or package in a box, must be modified to change its position each time you want to pack a fruit of another caliber , since the composition of the layer of fruits to be packaged has a different shape and number of fruits, which is a complementary work having to change each cup holder place, which results in a waste of time and energy.

OBJECT OF THE INVENTION

The present invention aims to provide the market with a device for a fruit packer machine, which has been designed to create a large air flow by means of a motor-driven vacuum turbine connected to a duct with spring means, which has a lower associated a wide-mouth air absorption hood, which is partially closed by a grille with suction grooves, as a template, which creates a greater contact surface with the pieces of fruit sucked at the same time, even though these carry stems with leaves, or have the most rough skin and the most ellipsoidal shape, as with certain dtricos such as lemon, which are also retained to the large surface of the template maintaining greater contact with it, due to the large flow of air aspirated .

In addition to assist in the retention of the load of the aspired fruit, it is foreseen to provide an elastic curtain of containment of the fruit, following the contour of the mouth of the hood of absorption of air, which when sucking the air into the interior of the hood, the stretches of elastic curtain adhere to the outermost fruit retained by the template, with which the retention of the load of fruit is achieved, preventing its involuntary fall during the transfer of the load to the box.

In order to absorb loads of fruit of different caliber and with a number of fruit units determined, it is provided that the template is removable from the absorption hood to be replaced by other templates that have different number of slots and different width of said slots.

Likewise, in order to raise and retain a load with a greater number of pieces of fruit to be transferred to boxes of greater dimension, it has also been foreseen that the bell with a larger dimension can absorb more air flow, when it is plugged in less to two air ducts connected to their corresponding aspiration turbines driven by motors.

Likewise, when it is intended to retain fruit loads with a smaller number of pieces of fruit, to be transferred to smaller size trays, it has been foreseen that the absorption bell connected to the same suction tube is divided by internal partitions in two. small symmetrical bells provided each one of them in its rectangular embouchure of a template, allows it to retain two loads of fruit with a smaller number of pieces.

DESCRIPTION OF THE INVENTION

According to the invention, the device for a fruit packing machine, object of the invention, is capable of sucking a fruit layer according to the invention. a disposition or mosaic of specific fruits, to be transferred inside a box for transport and trade.

For this purpose, the device is constituted by a vacuum turbine with a large air flow, which is driven by a motor, and connected to a flexible vertical duct of suitable dimensions, so that the large flow of air sucked through flows therein.

The aspiration duct is provided throughout its longitudinal perimeter with a helical spring, which allows it to elongate or contract by the action of an arm with vertical displacement of a packing machine, in order to perform the corresponding work cycles.

Said flexible conduit is connected at its lower end, by means of a mounting flange, to an air absorption hood, which gradually widens towards its base having a rectangular contour, and in a position to be arranged to absorb a large volume of water. outside air when the turbine is activated.

The air absorption hood, which is hollow, is partially sealed in proximity to its mouth, by a rectangular template provided with air suction grooves, which allows a load to be lifted and retained through the suction grooves. of pieces of fruit of the same caliber, which will have the same composition or mosaic and number of fruits, as the layer of fruit that must fit the machine in a box for the transport and trade of the fruit.

To make the retention of the load of aspirated fruit more effective, it has been foreseen, by contouring the mouth of the air absorption hood, to have a curtain of elastic material for the containment of said load of fruit.

Said curtain of containment of the fruit conforms with the embouchure of the bell, by way of a rectangular cajeado, whose bottom is the template while the lateral walls of the cajeado are conformed by the elastic curtain, that by the action of the aspired air adheres to the extreme fruits of the load to retain them until they fit in the transport box.

All this is arranged in such a way that, the suction device for carrying out the working cycle of a packer machine is attached to the arm with vertical movement thereof, by the area of connection of the flexible conduit with the suction bell, thus in the vertical descent of the arm stretches the duct, lengthening it so that the absorption hood can reach a load of fruit arranged on a lower conveyor belt.

When said load of fruit is sucked by the bell through the template provided with suction grooves, the pusher arm is raised by contracting the device conduit and keeping retained the load of fruit lodged in the cavity determined by the template and the curtain of containment of the absorption hood.

Once the load of fruit retained by the absorption hood has been raised, the machine arm descends again, further extending the flexible conduit of the device until the bell with the fruit reaches the transport box, which comes from a conveyor belt disposed at a lower level than the fruit conveyor belt.

When the bell with the load of fruit is introduced inside the box, it stops operating the turbine vacuum leaving without retention the load of fruit that is deposited in the box forming layers, to then raise the arm of the machine that It contracts the flexible duct to its initial working position, in order to collect and transfer another layer of fruit to the box.

The invention has provided that the templates are covered by a layer of elastic material in order to avoid friction with the fruit sucked through the ventilation slots.

It is also provided that the aeration grooves are formed in a position parallel to the larger sides of the template and whose number of grooves and width thereof, can be varied according to the diameter and weight of the pieces of fruit, which they absorb at the same time through the template to form a specific composition or mosaic of a layer of fruit.

It has also been possible to verify in the tests carried out that the slots parallel to the long sides of the template are combined with other slots arranged delimiting the vertices of the template, or in parallel arrangement with the chamfers of the vertices, which favors a greater Absorption of the extreme fruits of the aspired fruit layer.

One, two or more fruit suction devices with their corresponding turbines connected to the flexible ducts and absorption hoods provided with templates can be used in a packing machine, which are attached to a transversal support of the same vertical movement arm of the machine packer, to do at the same time a multiple work of elevation and retention of layers of fruit of the same caliber and its transfer to transport boxes, which saves time, energy and cost in the packaging of the fruit.

The invention has also provided that the absorption hood with a larger dimension and driven by the same vertical displacement arm of the cassette machine, has the capacity to raise twice the load of fruit, for which purpose it has at least two holes in it. the upper base of the bell for the plug of the flexible ducts connected to the corresponding suction turbines, all arranged to retain a layer with a greater number of pieces of fruit to be transferred to larger boxes.

Likewise, it has been provided that the absorption hood connected to the same suction tube, incorporates two internal partitions forming an angle, in order to form the internal walls of two small symmetrical bells, each provided in its rectangular embouchure of a template , which allows to retain two fruit loads with a smaller number of pieces, to be transferred to trays or boxes of smaller dimensions.

In the first figure, it can be seen that the absorption hood is partially blocked by a rectangular template (7) provided with slots (8) for suctioning the air and in a position to suck at the same time a layer of fruit.

In the first and third figures it can be seen that the template (7) forms the bottom of a recess (9) in order to allow the elevation and retention of a load of pieces of fruit (10) of the same caliber, which will have the same composition or mosaic and number of fruits, that the layer of fruit that must fit the machine in a box for the transport and trade of the fruit.

In these figures it can be seen that in the contour of the embouchure of the absorption hood there is arranged an elastic curtain (11) for containing the fruit, which constitute the lateral walls of the recess (9) and which are ready to adhere by the aspiration of the air to the extreme fruits of the load to obtain a better retention until its fitting in the box (12).

In the fourth and fifth figures it can be seen that the jig (7) has a rectangular shape in plan and is provided with slots (8) for aspirating the air, which are formed in parallel arrangement with the long sides (13) and (14) ) Of the template.

Similarly, in the sixth figure it can be seen that the air suction slots (8) of the rectangular template (7) are of different length and are formed parallel to the larger sides of the template and in combination with other slots (15). ) that delimit the template vertices, which favors to obtain a better absorption of the extreme fruits of the aspired fruit layer.

In both cases the number of grooves (16) and the width of said grooves (17) of a template, can vary according to the diameter and the weight of the pieces of fruit (10), in disposition of being aspirated at the same time by Template.

The invention has provided that the templates are covered by a layer of elastic material in order to avoid friction with the fruit sucked through the ventilation slots.

In the seventh figure there is a fruit packing machine equipped with two fruit suction devices, initiating the work cycle. The vacuum hoods (5) of the devices remain on two equal loads of fruit (10), which come from a lower conveyor belt. At a lower level of the machine a second conveyor belt with two empty boxes (12) for packaging the aspired fruit is observed. In this position of the suction hoods, the flexible conduits (3) of the devices have been shortened by contraction of the coil springs (4) when ascending the vertical arm of the machine that operates the bells.

In the eighth figure, the same fruit packing machine with two fruit suction devices is observed in a second work cycle. It shows that the arm with vertical movement of the machine has descended until the absorption hoods (5) of the devices are arranged on the two layers of fruit (10) of the lower conveyor belt. In this descent of the bells, the flexible ducts (3) of the devices have been lengthened by the stretching of the coil springs (4) of the ducts pushed down by the arm of the machine.

In the ninth figure, the same fruit packing machine with two fruit suction devices is observed in a third work cycle. It shows that the vertical arm of the machine is in an upward position raising the absorption hoods (5) of the devices that elevate and retain the fruit layers. In this rise of the bells, the flexible conduits (3) of the devices have been shortened by the contraction of the coil springs (4) of said conduits.

Figure 10 shows the same fruit packing machine with two devices for aspiration of the fruit, in the fourth work cycle. In it it is found that the arm with vertical movement of the machine has descended until the absorption hoods (5) with the fruit loads (10) are placed inside the boxes (12) of the second conveyor belt. In this transfer of the fruit layer to the interior of the boxes, the flexible conduits (3) of the devices have their maximum elongation by the stretching of helical springs (4) of the conduits.

In the figure eleventh the same fruit packing machine with two fruit suction devices is observed, in the fifth work cycle. In it it is observed that the arm of the machine has ascended until raising the absorption hoods (5) of the devices to their initial position, for which purpose the flexible conduits (3) have been shortened by contraction of the coil springs (4) and in disposition to start a new work cycle.

In the figure duodecima one can observe a hood (5) of absorption of the air of greater dimension and that has the suction capacity sufficient to raise twice the load of fruit (10). This absorption hood with a large volume of aspirated air will be displaced vertically by the same arm of the machine that acts with the two devices.

For this purpose, the hood (5) has at least two holes (18) and (19) in the upper base (20) of the bell for the plug of at least two flexible conduits (3), which are connected to the corresponding aspiration turbines driven by motors and all of this in order to retain a layer with a greater number of pieces of fruit (10), to be transferred to a box (12) of a larger dimension.

In the thirteenth figure we can see the top plan form of the template (7) that is arranged inside the absorption bell (5) of greater dimension and greater suction power, as the two flexible ducts (3) and suction turbines are connected. Said template has suction grooves (8) aligned and parallel to the larger sides of the seedling, as well as other parallel grooves (15) to the chamfers of the vertices.
