    [0002] Procedure and dethroning device of a head of lettuce and installation of industrial peeling of a head of lettuce.
    [0003]
    [0004] Field of the Invention
    [0005]
    [0006] The present invention relates to a method for dethroning a head of lettuce after stripping it of the outer leaves and partially cutting it into pieces of leaves, as well as a dethroning device to implement the procedure and an industrial configuration for peeling lettuce heads by applying the procedure and / or the dethroning device. More generally, the invention applies to the dethroning of all types of vegetables that require such operation.
    [0007]
    [0008] State of the art
    [0009]
    [0010] It is known that lettuce heads can be peeled industrially by gradually cutting them after first cutting the edges of the leaves that are not edible and then cutting the leaves successively depending on their quality or taste or food interest.
    [0011]
    [0012] The final step is to detach the pieces of leaf that are retained from the trunk from the bases. To do this, the residue of the lettuce head, whose trunk is transported by a rotating support, is passed through a central cutting station. The station has a blade comprising a blade mounted on an actuator to be inserted at an angle in the trunk while the support rotates the trunk. This operation detaches the pieces of leaf from the trunk. Then, the trunk is removed and the support is put back into circulation to place a new head of lettuce to peel.
    [0013]
    [0014] This is an interesting solution for dethroning, but the leaf used for the operation is exposed to the variable characteristics of the trunks or the base of the head of lettuce that can still contain grains of earth or other relatively hard elements that quickly dent the knife. In such cases, the installation operations must be stopped to change the blade to be sharpened.
    [0015]
    [0016] There are also lettuces such as iceberg or Radicchio whose trunks are almost impossible to cut with a blade as described above.
    [0017]
    [0018] Due to the very variable resistance found by the blade in the different logs, it does not lose edge regularly over time, making it relatively difficult to predict when the blade needs to be changed.
    [0019]
    [0020] Thus, the drawback of this operation is that it is necessary to close the installation to replace the blade at relatively random intervals, to the detriment of the proper functioning and efficiency of the installation. It is also difficult to place the blade precisely on the log due to the flexibility of the blade and the difficulties it encounters to penetrate the log.
    [0021]
    [0022] Under these conditions, a relatively large safety distance must be left between the devices that are attached to the rotating support and the line of action of the blade that cuts the log. This generates substantial product losses.
    [0023] Field of the invention
    [0024]
    [0025] The purpose of the present invention is to develop means for accurately dethroneing a head of lettuce, even with a hard trunk, without interrupting the operations of the installation to replace the cutting device and reduce losses by placing more precisely the cutting point of the trunk at the base of the leaves.
    [0026]
    [0027] Brief description and advantages of the invention
    [0028]
    [0029] Therefore, the purpose of the present invention is a method of dethroning a head of lettuce, characterized in that the head of lettuce is cut transversely with respect to its axis, above the trunk, leaving a residue formed by the trunk and the remains of the leaves, while the residue revolves around its axis as a jet of cutting water that forms a cutting line is directed on the basis of the rotating residue to separate the remains of leaves from the trunk.
    [0030]
    [0031] This procedure has the advantage of efficiently cutting the trunk as close as possible to the base of the lettuce head, since the head has already been partially cut to separate certain parts of the leaves, generally classified into different quality categories.
    [0032]
    [0033] This procedure no longer requires the replacement of the cutting blade to trim the log, allowing faster and more efficient dethroning with greater efficiency than the known dethroning procedure.
    [0034]
    [0035] More advantageously, the force of the cutting jet is established according to the different hardnesses of the trunk and of the leaf ribs, so that the cutting axis shaves the surface of the log and cuts the base of the main leaf rib of lettuce without cutting the trunk.
    [0036]
    [0037] With the force of the cutting jet thus adjusted and with a cutting axis inclined sharply with respect to the trunk axis, it is possible to "follow" the surface of the trunk to cut the bases of the leaf ribs without affecting or cutting the trunk. This produces a very precise and efficient dethroning, not hindered by inaccuracies in the inclination of the cutting axis that would be caused by the fact that the natural shapes of the lettuce head stems are not strictly identical.
    [0038]
    [0039] According to another characteristic, the axis of the cutting jet is oriented so that it is substantially tangent to a midpoint with respect to the surface of the trunk TR.
    [0040]
    [0041] In this way, the adjustment of the power, as developed above, allows the cutting axis to follow the curved shape of the trunk surface and ensures effective dethroning even in the case of lettuces with particularly hard logs, since the cutting shaft does not have to cut the trunk.
    [0042]
    [0043] The invention also relates to an industrial process for peeling the lettuce heads using this dethroning process. This industrial peeling procedure is characterized in that each lettuce head is fixed to a rotating shaft support, different leaf parts of the lettuce head are cut successively by rotating the head with the rotating support around its axis in front of the blades for cutting pieces successive leaves, finally cutting the head of the lettuce transversely to its axis just above the end of the trunk leaving a residue of leaves, the residue is rotated and the jet of cutting water (cutting axis) is directed on the base from the trunk at the beginning of the leaves to separate the pieces of leaf from the trunk.
    [0044] The invention also relates to a dethroning device of lettuce heads for a peeling installation comprising: a rotating support for receiving the lettuce head attached to the support by its trunk, oriented by the axis of rotation of the support, a device for cross section to cut the head of lettuce transversely to its axis just above the trunk and form a residue comprising the trunk and the base of the leaves from the trunk, a cutting water jet lance, mounted in an adjustable way so that its cutting axis intercepts the volume of waste at the base of the blades, a supply of superpressurized water to the barrel and a control unit that manages the operations of the cross-cutting element, the rotating support and the cutting water jet cannon .
    [0045]
    [0046] This dethroning device is particularly compatible with an industrial peeling installation of lettuce heads that comprises a set of rotating supports for transferring lettuce heads between the entrance of the installation and the evacuation of the trunk deprived of lettuce leaves, a station of feeding to load the lettuce heads in the rotating supports, a succession of cutting stations to successively cut pieces of leaves depending on the products to be obtained, a dethroning device as specified above, downstream of the cutting stations for trim the waste trunk, collect the rest of the leaves and evacuate the bare trunk and a facility management unit that handles the synchronized operation of the dethroning device and the other components of the installation.
    [0047] Another advantageous feature of the industrial peeling plant is that the set of rotating supports for transferring lettuce heads comprises a carousel around which the various cutting stations and the dethroning device are arranged.

    [0063] Description of the embodiments of the invention
    [0064]
    [0065] Figure 1 is a diagram of a top view of an industrial peeling plant with 100 TS lettuce heads. This installation 100 comprises a transfer installation formed by a carousel 1 that receives the lettuce heads TS, placed automatically or manually, one by one, to feed the carousel 1 to the cutting stations P1, P2, P3 to prepare each head, then cut it in stages and collect separately the various parts of the lettuce leaves. These operations are carried out in a continuous kinematic procedure since the head TS is mounted on a rotating support 2 that transports the rotating carousel 1. The TS heads are joined by fasteners 21 to the rotating supports 2 that retain each trunk TR. The cutting operations end with the dethroning procedure, which consists of separating the last parts of the lettuce leaves connected to the base of the head TS around the end of the trunk TR. Then, the TR trunk, released from the leaf pieces, is removed.
    [0066]
    [0067] To simplify the description, it could be considered that the head of lettuce TS is an object of revolution with an axis of symmetry that passes through the trunk TR. It can be assumed that this axis of symmetry of the head of lettuce attached to the support 2 coincides with the axis of rotation RR of the rotating support 2.
    [0068]
    [0069] Successive cuts are made using rotating disc-shaped blades in front of which the TS lettuce heads pass while they rotate around their RR axis.
    [0070]
    [0071] The movement of the carousel 1 around its ZZ axis is a rotating movement with stopping the rotation each time a head of lettuce TS must be placed on a rotating support 2 when it arrives at the supply station Po. This brief stop is also used to dethrone, in the dethroning station P n whose adjustable barrel 41 generated by the cutting water jet is connected to its cutting line AA, the lettuce head TS is transported by the rotating support 2 which Turn along this AA cut line.
    [0072]
    [0073] Possibly other cutting operations can be performed on the fly.
    [0074]
    [0075] For the installation of a head of lettuce TS, it may be enough to simply reduce the rotational speed of carousel 1 temporarily; The same applies if the speed of rotation of the support 2 around its RR axis near the dethroning station P n is fast compared to the travel speed or the circulation speed in the TC trajectory of the carousel 1. The trunk TR it will then be dethroned on an enveloping surface that will not be strictly a surface of revolution.
    [0076]
    [0077] In more detail, the carousel 1 is a plate or box 12 mounted to rotate ZZ in a frame 11 and operated automatically or manually (see Figure 3).
    [0078]
    [0079] The operations of the installation 100 are managed by the control unit 160. In the installation 100 surrounded by a wall 150, the workstations P1 ... P n are located around the carousel 1, downstream of the supply station Po, where an operator or an automatic loader presents the head of lettuce TS one by one, with the trunk facing the rotating support 2. The head of lettuce TS is then hung by its trunk TR by automatically inserting the fastening devices 21 of the rotating support 2 The assembly comprising the support 2 carrying the head can then rotate around its axis of rotation RR.
    [0080]
    [0081] The supply stations Po are followed by the cutting stations P1, P2, P3 ... through which the circular path TC of the lettuce heads TS passes. Each cutting station P1, P2, P3 ... comprises one or several rotating blades 31, driven by a motor 32, preferably in the form of a disc and over which the head of lettuce TS passes while rotating around its RR axis. Depending on the successive parts of the leaf to be cut from each head of lettuce TS, the blades 31 act separately or simultaneously. The parts of the cut sheets are evacuated and collected separately by means of transfer not shown.
    [0082] The last part of the installation is the dethroning station P n that receives the residue E4 from the head of lettuce cut transversely above the trunk TR.
    [0083] The dethroning station P n includes the dethroning 4 of the blanks, which is described in detail below.
    [0084] In a variant, if this cross-section has not already been made upstream, there is a cross-sectional device 3a incorporated in the dethroning station P n.
    [0085] The dethroning station P n to which the residue E4 of the lettuce head TS transported by the rotating support 2 arrives, includes a water jet cannon 41 whose cutting axis AA is configured to point to the trunk TR in the manner as tangent as possible and cut the base of the leaves to separate them from the TR trunk.
    [0086] In practice, the orientation of the axis AA in an exact tangent to the envelope of the trunk is not possible because the trunk TR does not end on a surface of conical rotation. However, by establishing the cutting axis AA as close as possible to the clamping devices 21, it moves near the base of the main ribs of the leaf crowns of the lettuce; by means of an angular sweep (slight variation in angle a) it is possible to point to the successive crowns of leaves of the base during the rotation of the trunk TR. The power of the adjustable jet to adapt to the nature of the lettuce should be sufficient to cut the main rib of the lettuce leaves without damaging the trunk, since it is much harder than the main ribs of the leaves. The projected drops deflected by the surface of the TR trunk have enough energy to cut the base of the ribs in successive peripheral paths, without cutting the trunk itself and thus leaving hard chunks at the base of the ribs of the cut leaves.
    [0087] After this dethroning operation, the clamping devices 21 are opened and the bare trunk TR falls from the support 2 which once again reaches the supply station Po.
    [0088] The various preparation and cutting operations are schematically represented in Figure 2 in which Parts 2A-2D represent the head of lettuce TS in its inverted position, suspended so that the base of the trunk TR (is above) hung from the side of support 2 and rotates around its RR axis.
    [0089] - Part 2A shows two blades C1, C2 used to cut and cut the head of lettuce TS by the planes shown, to detach the inedible ends of the leaves; the intact cutting head remains in its E1 state.
    [0090] - Part 2B shows the second stage of using the blades C3, C4, C5 to make a succession of three cuts of the upper part (blade c3), the peripheral side (blade C4) and the base of the outer blades ( blade C5) to separate these leaves from the base of the trunk, leaving the cut head intact in its E2 state.
    [0091] - Part 2C shows the following cuts of the upper part (blade C6) and the peripheral wall (blade C7) leaving the cut lettuce head intact in its E3 state.
    [0092] - The 2D part shows the last cut before dethroning to remove the heart from the lettuce (blade C8). This cut is made substantially transverse, that is, perpendicular to the axis of rotation RR of the lettuce. The part of the lettuce near the tip of the trunk that constitutes the residue under E4 around the trunk TR remains.
    [0093] - The last operation, dethroning, is not represented in this sheet of figures; will be described below using the dethroning device according to the invention.
    [0094] In the current state of the art, dethroning is performed with a pointed blade with a straight blade held at an angle with respect to the axis of rotation RR with the head of lettuce TS in its state E4. The blade is oriented in the direction d (part 2D) while the part E4 of the head of the lettuce rotates; in this way he cuts the base of the trunks of the leaves of the trunk with a conical shape, separating the last pieces of the lettuce leaves while leaving significant parts of the leaves still attached to the trunks.
    [0095] The trunk is released from the rotating support 2 which returns to the supply station Po to receive a new head of lettuce to be prepared.
    [0096] Figure 3 is a simplified front view of the industrial stripping installation 100, limited to the part thereof located in the dethroning station P n . The frame of the machine 11 carries the carousel 1 with rotating supports 2 equipped with hook-shaped fixing devices 21 that allow the head of lettuce TS to be firmly fixed and retained on each rotating support 2. The carousel 1 carrying the supports 21 in this case is made of a bicone-shaped box 12 with a hexagonal section and facets equipped with four rotating supports 2.
    [0097] The box 1 houses the equipment to guarantee the stop or rotation of the supports around its RR axis and to actuate the fixing devices 21.
    [0098] According to Figures 1 and 3, the dethroning device 4, analyzed separately from the installation, consists of:
    [0099] - a rotating support 2 that receives the head of lettuce TS,
    [0100] - a hyperbaric water jet cannon 41 of adjustable, controlled force, transported by the adjustable davit 42 to direct the cutting jet on the base of the lettuce head TS as close as possible to the fastening devices 21 of the TR trunk which hold it to the swivel stand 2.
    [0101] The cutting water jet cannon 41 has a nozzle defining the axis AA of the jet, which is the cutting axis. The adjustable high pressure water supply, for 200 MPa, is provided by a pipe 46 from a pressurizer 47 with a loop 461 to absorb the adjustment movements of the barrel 41. The davit 42 includes a column 421 adjustable in RV height and a horizontal arm 422 for horizontal adjustment RH and ending with a pin 423 that carries barrel 41.
    [0102] Column 421 is equipped with an actuator 43 for vertical adjustment RV and arm 422 is equipped with an actuator 44 for horizontal adjustment RH. The pin 423 is connected to the arm 422 by means of an actuator 45 to adjust the orientation angle a of the axis AA in the plane of the figure. But it is also possible to use an actuator 45 that allows a rotation movement in all three axes.
    [0103] The adjustment of the cutting axis AA in its position and angle is controlled remotely. This may involve a series of preset configurations based on the geometric characteristics of the lettuce, in particular in the trunk area, to adapt these configurations precisely to dethroning, in addition to cutting the leaves. The configuration can also be done with the naked eye, in a stationary installation 100 and a dethroning station P n which can be safely accessed.
    [0104] The cutting control is synchronized with the rotation movement of the carousel 1 by turning the barrel 41 on and off by means of a program.
    [0105] Figure 3 shows a ramp 5 below the dethrone area to pick up loose pieces of leaf. Decks or screens partially surround the dethroning area. These media are not shown.
    [0106] Figure 4 shows the details of the dethroning device 4 consisting of the rotating support 2 combined with the adjustable jet barrel 41 by the davit 42 and which supplies a water flow adjusted to the water jet, directed along the axis of AA cut. The barrel 41 is mounted on a collar support 424 of the adjustable pin 423 so that it can be easily removed for maintenance operations.
    [0107] The rotating shaft support 2 of the RR axis has three fixing devices 21 in the form of retractable claws shown here in the retracted position. The three claws 21 have a curved arm 21a mounted on a pivoting tongue 21b and a controlled lever 21c. The water jet lance 41 carried by the rod 42 is adjustable in the XY plane and with an inclination (angle a) in relation to the rotation axis RR of the support 2 and the lettuce head, which allows precise placement of the AA cut line in relation to the trunk.
    [0108] Figure 5 shows the operation of the dethroning device 4 in action on a residue E4.
    [0109] The residue E4 of a cut lettuce head perpendicular to its axis RR, near the end of the trunk TR, is transported by the unspecified claws 21 of the rotating support 2. The cutting axis AA of the barrel 41 is directed to pass as close possible of the claws 21 and minimize the loss of leaves.
    [0110] The cutting axis AA adjusts to a flush position to the natural surface, not exactly the trunk TR curve.
    [0111] With few exceptions, the TR trunks of a series of TS lettuce heads have approximately the same shape, so that the adjustment of the angle and position of the cutting jet materialized by the AA axis will be the same. This axis AA is substantially at the base of the main ribs N of the successive leaf crowns of the residue E4. The resistance of the jet is adjusted according to the relative hardness of the base of the main ribs and the trajectory: the hardness of the trunk, in comparison with that of the ribs and even with that of the base of the ribs, is different enough to allow a suitable configuration of the jet so that it cuts the ribs without cutting the trunk. The adjustment may be within the limit of this pressure range, so that even if the point of impact PI of the jet on the rotating trunk TR does not exactly correspond to a crown of rib bases NB, the energy of the droplets diverted after its impact at the point of impact PI is sufficient to detach the leaves. This effect is used if the cutting axis AA cannot be at a flush angle (angle al) as shown in Figure 5 and the angle must be widened a2 as in Figure 6.
    [0112] Figure 6 schematically shows the case of a cutting axis AA that is not at a flush angle (tangent) to the surface of the trunk TR. Schematically, the rib rings N1, N2, N3 are generally cut successively during the rotation of the residue E4, allowing the cutting jet to move from a ring N1 to the next ring N2 and then to the next ring N3. The cut clears the ring N1 giving access to the next ring N2, even if it is not exactly at the intersection of the cutting axis AA and the trunk surface TR. The return of the drops to the surface of the TR trunk is schematized by the RA lines.
    [0113] The jets of drops RA diverted at the point of impact PI of the cutting axis AA and the surface of the trunk TR work successively on the rib rings N1, N2, N3 and cuts them.
    [0114] The setting of the force of the cutting jet is adjusted according to the experimental data collected for different types of lettuce.
    [0115] It should be noted that E4 residues are cut parts of TS lettuce heads with fairly uniform dimensional and geometric characteristics within the limits of plant products. The characteristics of the configurations of the angle a and the point of impact PI of the cutting axis AA must be interpreted in this context of possible accuracies for natural products.
    [0116] In this way, in particular, the point of impact PI of the cutting axis AA and of the surface of the trunk TR is, when this is possible, a point tangent to this surface, with some inaccuracy since the trunk TR rotates and its surface It is not a surface of revolution. The point of impact PI is an average point located well at the base NB of the first ring N, N1 of the ribs or between this ring and that of the following ribs N2, N3.
    [0117] The adjustment of the power of the jet is subject to the same considerations, although the obvious difference between the hardness of a log and the ribs of its leaves accepts an adjustment that requires less precision.
    [0118] Finally, it is worth remembering that, since the cutting and dethreading operations are carried out during the rotation of the waste E4 around its axis, the point of impact or tangent moves in a "circular" curve.
    [0119] While the above description refers to lettuce heads, the invention applies to any type of plant with a trunk that supports leaves, such as a cabbage, that requires such dethroning. Therefore, the term lettuce head should be used in a non-restrictive sense for the application of the dethroning process and the device depending on the invention.
