Description

FIELD OF THE INVENTION The field of the present invention is that of agricultural machines, in particular that for the extraction of kernels or almonds which are contained in hard-shelled fruits.
The exploitation of walnut orchards is faced with the problem of extracting the kernel, or kernel, contained inside the hard wooden shell, itself contained in a biodegradable bug. If it is relatively easy to separate the shell of the bug, it is more difficult to extract the kernel from the hull, without damaging it and preventing it from breaking during this extraction. The processes currently used to break the hull and extract the kernel are essentially based on machines that push jaws towards one another and come to break the hull by crushing. A cone shape is generally given to the jaws, which allows the machine to adapt to hulls of different sizes. This process remains inefficient and results in high scrap levels in kernels. It also requires, in addition, important manual work to eliminate cockle shells kernels. The object of the present invention is to remedy these drawbacks by proposing a machine and a process which make it possible to separate the kernels from the hulls, without the former being damaged during the opening of the hull, and which substantially reduce the manual operations. to perform after this separation. GENERAL PRESENTATION OF THE INVENTION To this end, the subject of the invention is a process for separating the kernel from a hard-shelled nut for which the kernel is contained in said shell with a space left free between the kernel and the shell, characterized in that it implements a sawing of said shell with penetration of the teeth of the saw blade or blades to a depth allowing them to reach said separation space of the kernel of the hull, without reaching the kernel.
This process opens the hull and makes the kernel appear, without damage to the saw blades. The dislocation of the shell and its separation into several elements makes it possible to evacuate it by conventional means, such as blowing, after sawing and to recover an intact kernel.
Preferably the method is implemented for ovoid-shaped nuts which are then previously oriented so as to have their axis of symmetry perpendicular to the plane of the saw blade or blades. The invention also relates to a device for separating from its shell of the kernel a hard shelled nut for which the kernel is contained in said shell with a space left free between the kernel and the shell, said device comprising a storage container for whole nuts, a device for gripping the nuts in said container and for subsequent release of said nuts, a device for transferring the nuts thus released to the place of execution of the separation and a device for dislocating the hulls to perform said separation, characterized in that said dislocation device is a sawing machine of said shells. Advantageously, the saw blade (s) protrude from a cutting table against which the nuts are pushed during sawing, at a constant height along the path of said nut on said cutting table, said height being shaped to allow the teeth saw blade (s) to reach said separation space of the kernel of the hull, without reaching the kernel. In a particular embodiment, the saw blade or blades are circular, the cutting table having on its portion facing said blades a cylindrical curvature concentric with that of said blade or blades. Preferably, the cutting table is arranged to roll the shell on itself in a plane parallel to the blade or blades of the sawing machine, during its course on said cutting table. This ensures that the cutting of the shell takes place well over its entire circumference by maintaining a fixed point of sawing. More preferably the cutting table of the sawing machine has a non-slip layer on its face in contact with said nuts. The rotation is not disturbed by any slip phenomena associated with the rolling of the hull. In an alternative embodiment the transfer device is shaped to let the free nuts rotate on themselves in a plane parallel to the blade or blades of the sawing machine, at least for its part facing the cutting table. Preferably, the transfer device comprises concave rollers free in rotation about axes parallel to each other and perpendicular to the direction of advancement of said transfer device. The concavity of these rollers makes it possible to place the nuts that fall from the gripping and releasing device in a predetermined position. More preferably the rollers are in the form of diabolos, the concavity of the diabolos corresponding, recessed, to the convex shape of the shells so as to form, between two adjacent rollers, a retaining cradle for said nuts. Advantageously the gripping and releasing device is shaped to provide a nut to the transfer device that is due to one for two consecutive rolls. It is thus shaped so that two consecutive rolls are independent of the adjacent rollers and leave all freedom to the nut to orient in the desired direction. The invention also relates to a device in which the transfer device passes the nuts on a vibrating table between the gripping and release device and the cutting table, the vibrations being oriented in a vertical direction. The yawning of the nuts thus caused, associated with the concave shape and the freedom in rotation of the rollers, ensures the horizontal alignment of the axis of symmetry of the nuts and their good positioning vis-à-vis the saw blades for an ideal cut of their hull. PRESENTATION OF THE FIGURES The invention will be better understood, and other objects, details, characteristics and advantages thereof will appear more clearly in the following detailed explanatory description of an embodiment of the given invention. by way of purely illustrative and non-limiting example, with reference to the accompanying schematic drawings.
In these drawings: FIG. 1 is a front view of a nut shell cutting device, according to the invention; FIG. 2 is a detail view of FIG. 1, showing the cutting table for sawing the shells; FIG. 3 is a bottom view of the cutting table of FIG. 2; FIG. 4 is a side view of the cutting table of FIG. 2; FIG. 5 is a sectional view of FIG. FIG. 6 is a top view of the hull conveyor of the device according to the invention, and FIG. 7 is a side view of the conveyor of FIG. 6.3. DESCRIPTION One Embodiment and Implementation With reference to FIG. 1, we see a device for sawing nutshells, previously discarded of their bug, in order to operate a separation of their kernel, shell. The nuts 1 are poured into a hopper 2, in which they descend by gravity to end in front of a low opening, where they come, one by one, to press, under the weight of the column of nuts, against a drum 3 which is rotated. This drum is formed by a cylinder of revolution with horizontal axis whose internal volume is put in depression. The portion of the outer surface of this drum which circulates opposite the lower opening of the hopper is also pierced with orifices which, due to the internal depression of the cylinder, form a suction means for the nuts 1 which arrive at the bottom of the hopper 2. When the passage of a suction opening in front of the lower opening of the hopper, the lowest nut sticks to it so that it is then rotated upwards, by the drum 3. Inside the drum 3 is a plate 4 for masking the suction ports, which extends over an angular sector opposite the suction surface and which is not rotated. Its function is to suppress the vacuum suction effect on the corresponding angular sector of the drum. For this, conventional sealing means are arranged between the inner, movable face of the drum 3 and the masking plate, fixed, 4 so that the suction is no longer exercised on the angular sector considered. This plate 4 extends circumferentially from the low point of the drum 3, where the nuts can fall from a low height on a conveyor 5, because of the stop of the suction, to the point that makes facing the low opening of the hopper. In this way, the drum 3, with its depression, forms a means of gripping and loosening the nuts 1, these describing a large arc, which starts from the lower opening of the hopper 2, which passes through the top of the drum and down to the bottom of the drum, where the nuts are released.
In alternative version the gripping drum 3 can be replaced by a device, such as a bucket which is rotatably mounted at the end of a handle on a horizontal axis and which is immersed in the tank at the bottom of the hopper 2. It is configured to pick up a nut in this lower part and deposit it, after its rotation, on a descending gutter, with a U-section, which conveys it to the conveyor 5. A paddle wheel holds the nuts on the gutter and does not release them that due to a nut for the passage of two rollers on the conveyor as will be explained later. Below the gripping and release drum 3 is seen in Figure 1 a conveyor 5 which has for first object to route the nuts 1 to a device for sawing their hulls, which will be explained in more detail in the following. description, and second object to position and orient them in a particular direction vis-à-vis the sawing plan. The conveyor 5, which will be described in more detail with reference to Figure 5, is constituted by a succession of rollers 6 of revolution, which are positioned horizontally, parallel to each other. Their axes are carried by two chains 7 which drive them by describing a closed cylindrical path to go and return in a vertical plane. The chains 7 are carried by vertical pinions 8, at least one of which is a driving pinion. Due to this drive the rollers, which are free to rotate about their axes, are moved in translation, perpendicular to their axis, from a receiving position of the nuts 1 which is located below the low point of the drum 3 to a table cutting 9 where the shells will be cut. The spacing between two consecutive rollers is such that both of them form a cradle for the nuts 1 they convey. The forward path of the conveyor, that is to say that which is between the low point of the drum 3 and the output of the cutting table 9, is essentially horizontal, with the exception, however, of its part which is situated under the cutting table where it follows the curvature of the saw blades. The distance between the rollers 6 and the cutting table 9 is such, at this point, that a standard diameter nut, which rests between two consecutive rollers, is in pressure against the surface of the cutting table, so as to rotate on itself as will be explained in detail later. After passing under the cutting table 9, the conveyor 5 takes a return path which closes the path followed by the rollers and which brings them back to the position below the low point of the drum, where they are again positioned to carry out a new nut transport cycle. The path of the conveyor passes, moreover, between the low point of the drum 3 and the cutting table 9, on a vibrating table 10 which raises the rollers 6, and consequently, the nuts 1 which are placed on them, then who dropped, which makes it possible to give the same orientation to all the nuts 1, as will be explained with reference to FIG. 6. To improve this process of aligning the axes of the nuts, a brush (not shown in the figure) can be added above the vibrating table 10. It is then positioned above the path followed by the nuts and has the shape of a cylindrical tube which is rotated about its axis oriented vertically. It is formed by a series of flexible bristles whose length is such that they touch the nuts when they are not positioned horizontally but do not touch when they are in the desired position, called horizontal. The friction of the hairs on the shells, whether during the first passage of the nut under the bristles entering the tube, or during its second passage, at the outlet of the tube, helps the nut to come into the position horizontal. This additional device makes it possible to improve the rate of correct placement of the nuts before sawing and avoids human interventions that could be too frequent.
Referring now to Figure 2, we see the device for sawing hulls according to the invention. It comprises several saw blades 11, very thin, which are positioned parallel to each other on a common axis of rotation. The lower part of these blades passes through the cutting table 9 to a predefined height h. This height is rigorously calibrated so that the saw or saws 11 can cut the shell of a walnut without reaching the kernel that is therein. The cutting table 9 is flat at its two upstream ends 9a and downstream 9c, that is to say where the nuts 1 arrive by the conveyor 5 and where they leave after sawing, and it is curved over its entire length. central part 9b, that is to say where the sawing of the hull of walnuts occurs. The curvature given to this central portion is concentric with that of the cutting edge of the saw blades, so that the same height h is found all along the curved portion 9b of the cutting table 9. FIG. cut 9 in view from below. Dashed lines show the separation between the central curved portion 9b and the flat, end portions 9a and 9c. It is cut along the entire length of its central portion by four linear slots 13 which are intended to pass the radial end of the four saw blades 11. These slots 13 extend longitudinally, that is to say according to the direction of displacement of the conveyor 5, over the entire central portion 9b and overflows on each side so that the shell of a nut is attacked by the blades 11 while it is still on the flat part of the path go of Conveyor 5. The total length of each of the slots is also substantially equal, and preferably slightly greater than the average circumference of the nuts usually encountered, so that by causing them to rotate 360 ° in a vertical plane while they describe the length of the slot 13, they have their entire circumference to the saw blades and thus be proceeded to a complete cutting of their hull.
Figure 4 shows the same blades 11 and the cutting table 9, in section along a vertical plane, transverse to the sawing plane. In the configuration shown, only two slots 13 are present for a better clarity of the drawing, without the number of slots is an essential factor for the realization of the invention. As indicated above, the four blades 11 pass through the cutting table 9 downwards and overflow with a height h. As regards the cutting table it is constituted, as can be seen better in Figure 5, two layers of materials glued to each other. A first layer 91, preferably metal to ensure mechanical strength, carries, along its length, a second layer 92 of non-slip elastomeric material, of the type of a rubber. This non-slip material is intended to prevent relative sliding of the nuts 1 relative to the cutting table 9 and to force them to rotate on themselves and thus always to present a part of the shell still intact to the blades of saw 11. As shown in Figure 5, without this configuration is imperative, the second layer 92 may have aliasing to improve the anti-slip function of the shells on its material. FIG. 6 shows, in plan view, a section of the conveyor 5, in its forward path, which leads the nuts 1 which it collects at the outlet of the drum 3, towards the cutting table 9.
As indicated above, it consists of a series of concave rollers 6, each having the shape of a diabolo. These rollers are carried by axes 14 which pass through their axis of symmetry and on which they are mounted free in rotation. Only their axial position is fixed, by means of conventional means of restraint which are not described here. The concavity of the rollers 6 is such that it substantially corresponds, hollow, to the curved shape that is observed on average on the nuts to be cut. In this way the nuts 1 have a natural tendency, helped in this by the solicitations of the vibrating table 10, to come to place their axis of symmetry (by assimilating them in first approximation to ovoids of revolution) collinearly with that of the rollers 6.
The axes 14 of the rollers 6 are fixed at each of their ends 14a and 14b, on two chains 7 which each extend in a plane perpendicular to the axes 14 forming a closed loop in a vertical plane. These chains rest on pinions 8, free or driving, as has been described with reference to Figure 1, and form a means of advancement of the conveyor 5 and its rollers 6.35 Figure 7 finally shows, in side view, the position taken by the nuts, after their passage on the vibrating table 10, in the gap left between two consecutive rollers 6. They are then in a so-called horizontal position, that is to say that their axis of symmetry is in a horizontal position, with the joining surface of their two half-shells in any circumferential orientation. It should be noted that the nuts 1 are disposed on the conveyor 5, at a rate of one every two rollers 6. In this way each roll 6 of a pair of rollers carrying the same nut 1, can turn on it even independently of the position of the rollers which are adjacent to this pair. This ensures that the nut 1 is properly positioned in the bottom of the gap which is located between two rollers and in the middle of the axial length of these rollers. It is thus correctly placed laterally, with reference to the direction of the axes 14, and is therefore perfectly positioned for the saw blades 11 to attack the hull at the desired locations. The slices of hulls then have all appropriate widths, without one of them being too narrow while another would be too wide. The elimination of slices of hulls, after sawing, will be facilitated accordingly. To obtain this arrangement of a nut placed every two rolls, the spacing of the suction orifices on the circumference of the drum 3 is defined so that it is equal to the distance which exists between the axes 14 of two rollers 6. consecutive and separated from each other by the presence of a third. We will now describe the operation of the device according to the invention for separating a kernel from the shell of a walnut. The nuts 1, cleared of their bugs, are poured into the hopper 2 where they come to squeeze in the bottom and position, for one of them, opposite the lower opening of the hopper. It is then sucked by the depression which is created inside the drum 3, at one of the suction ports and is driven by the rotation of the drum, on which it remains attached. When the drum has rotated such that the suction port of the nut 1 in question faces the beginning of the masking plate 4, the suction is cut by this plate and the nut 1 falls naturally from the drum 3. It then rolls to be placed at the bottom of the first gap, free, located between two rollers 6 of the conveyor 5. As indicated above, the spacing between two suction ports of the drum 3 is calibrated so that each nut is positioned between two consecutive rolls and that these are dedicated to this unique nut.
The spatial position of the nut in this interval is then unsuitable and unsuitable for its presentation in front of the saw blades 11. The rollers 6 of the conveyor 5 then pass on the vibrating table 10 which makes the nuts hop. This entails, on the one hand, that they position themselves well at the bottom of the interval between rollers and therefore in a well-defined lateral position and, on the other hand, in the so-called horizontal position, therefore adapted for presentation to the blades. of saw. They can instead position themselves back-to-back with respect to each other, without this configuration is detrimental to the proper operation of the device for separating kernels from their shells, the number and arrangement of the saw blades being defined accordingly.
At the output of the vibrating table 10 the nuts are directed towards the cutting table 9 and its upstream end 9a due to the advancement of the conveyor 5 which is generated by the rotation of the driving pinion 8 of the chains 7. The nuts 1 are then pressed against the table 9 because of the reduced space that is left between this table and the rollers 6. The adjustment of the pressure of the nuts against the saw table 9 is ensured by the tension which is given to the chains 7 drive of the conveyor 5. Furthermore, the non-slip material of the second layer 92, associated with the freedom in rotation of the rollers 6, causes the nuts 1 to turn on themselves about their axis of symmetry and thus to present the entire circumference of their Hull to the teeth of the saw blades 11. Given the length of the cutting table 9 which is defined as being slightly greater than the circumferential length of the shell, the nut 1 rotates 360 ° on itself in describing the length of the table and the whole of its shell can be cut by the saw blades 11. Moreover, the calibrated height h is such that the blades of the saws 11 penetrate into the shell sufficiently deep to perform the cutting of this one, irrespective of its irregularities, and sufficiently shallow so that the kernel is not damaged by the teeth of the saw. At the output of the cutting table 9 the conveyor arrives at the end of its path to go and rotates on itself in a vertical plane to initiate its return path to the drum 3. Its tilting causes the nut 1 to fall to be cut by the blades 11 and the assembly formed by the kernel and the slices of hulls now dissociated falls into a collection container (not shown) where the separation of the kernel can be effected. This is then conventionally carried out by blowing, carried out by a machine of the sort enoiseuse, which evacuates the hulls and which leaves the kernel in the bottom of the container, this blowing being eventually completed at the margin by a manual action to solve the problems. some residual litigious cases.
The invention has been described with a sawing of the shell of the nut using four saw blades which are arranged parallel to each other, which generates the cutting of the shell into five slices, three having the shape of tubes and two having the shape of caps.
It can equally well be performed with a single saw blade that cuts the shell in its longitudinal center, then forming two half-shells that should be separated from one another to extract the kernel, or even with two or three blades. The multiplicity of the blades facilitates the subsequent separation of the kernel with the slices of shells, without this multiplicity is essential to the embodiment of the invention.
Similarly, the introduction of a drum 3 provided with suction openings may be replaced by any device which is able to grip the nuts 1 in a feed tray 2 and, subsequently, a loosening of these nuts to be collected, with the proper spacing, by a transfer device to a cutting table 9.
Finally, the presence of a vibrating table improves the effectiveness of the isolation device of the kernels by positioning all the shells in the same orientation, which facilitates the subsequent sequence of separation of the shell slices of kernels. As indicated above, the vibrating table is advantageously completed by the action of a flexible bristle tubular brush which acts mechanically on the nuts whose height above the conveyor is important. The invention could equally well, in a simpler, more rudimentary mode, not implement a vibrating table and let the shells cut themselves in the position where they arrive on the conveyor 5. Finally the invention has been described with a nut to walnut but it is obvious that walnuts must be understood to mean any hard-shelled fruit that contains an almond or separable kernel, which is positioned inside said hard shell.
