    [0001] description
    [0003] Method and machine for making an edible roll
    [0005] The present invention aims at a method and a machine for the production of an edible roll.
    [0007] By the term "edible roll" is meant the assembly that includes a food product around which a strip of dough is spirally wrapped.
    [0009] The food product is normally elongated in correspondence of its own axis along which it has two opposite axial ends. This elongated shape may be due to the nature of the food product itself and / or to further processing. Examples of food products can be: sausages, salami, cylinders
    [0010] or food bars, for example, based on cheese and / or fruits and / or vegetables, etc.
    [0012] The dough strip is spirally wrapped around the food product starting from one of
    [0013] its axial extremities and even covering it along its entire axial length.
    [0015] The edible roll can have closed or open ends, or it can be further divided in half and form a food pipe.
    [0017] To date, it is known to manually wrap a layer of dough around a food product. This manual operation is slow and imprecise and can generate small openings in the layer of dough that can cause, in a second moment, the leakage of the filling and also unpleasant aesthetic results. These disadvantages are accentuated in the case of high daily productions.
    [0019] In this context, the technical task on the basis of the present invention is to propose a method and a machine for the production of an edible roll that overcomes at least some of the aforementioned drawbacks of the known technique mentioned above.
    [0021] Specifically, it is an objective of the present invention to make available a method and a machine for the production of an edible roll that allow a production automated in shorter times with respect to the known technique and with a better quality.
    [0023] Finally, it is an objective of the present invention to realize a method and a machine for the realization of an edible roll that can be used by any operator, regardless of their manual abilities.
    [0025] The clarified technical task and the specified objectives are substantially achieved through a method and a machine for the production of an edible roll, which include the technical characteristics set forth in one or more of the appended claims.
    [0027] In one or more of the indicated aspects, the present invention may include one or more of the characteristics indicated in the dependent claims, incorporated herein by reference, each of which corresponds to a possible embodiment.
    [0029] Further characteristics and advantages of the present invention will appear more clearly from the description that is indicative, and therefore not limiting, of a preferred, but not exclusive, embodiment of a method and a machine for the production of an edible roll.
    [0031] This description will be set forth below with reference to the attached drawings, which are provided for indicative purposes only and, therefore, not limiting, where:

    [0046] figure 5b shows, in view from above, the third part of the machine for making an edible roll illustrated in figure 5a.
    [0048] With reference to the aforementioned figures, a machine for making an edible roll 4 has been indicated in complex with the reference number 1, hereinafter indicated, for simplicity, machine 1.
    [0050] The edible roll 4 is made by wrapping a dough strip 9 around a food product 19 having an elongated shape along an axis 20 between two ends 19a, 19b.
    [0052] The machine 1 includes a frame 2. In particular, the frame 2 includes support portions (not shown in the attached figures) that keep the rest of the machine 1 raised from the ground.
    [0054] The machine 1 includes a forming member 3 mounted on the frame 2 that runs along a forming path F from a first inlet station 5 of the dough to a proper outlet station 6 of the edible roll 4. Even more in detail, the forming member 3 has, from the inlet station 5 to the outlet station 6, a cutting station 7 of dough strips 9 and a wrapping station 8 of the dough strips 9 in the food product 19 .
    [0055] The forming member 3 also includes advance means 10, for transporting the dough along the forming path F from the entrance station 5 to the exit station 6. In detail, the forming member 3, correspondingly of the input station 5, includes a motorized unwinding shaft A and activatable on a dough roll 54 placed thereon. In other words, in use , the dough roll 54 is mounted on the unwind shaft A and unwound so as to position a dough belt in the advancing means 10.
    [0057] In fact, the roll of dough 54 comprises this ribbon of dough wrapped on itself . This roll of dough 54 is of the commercially known type and will therefore not be described further hereinafter.
    [0059] Furthermore, the forming member 3 includes, after the unwinding axis A along the forming path F, cutter rollers 55 active on the dough strip to cut it laterally depending on the width of the dough strip to be obtained. These trimmer rollers 55 are spaced from each other and operate on the lateral margins of the dough belt.
    [0061] Furthermore, the dough tape, after having been cut laterally, is cut into dough strips 9 at the cutting station 7. Specifically, the forming member 3, at the cutting station 7, includes means cutting machine 56 cyclically active on the dough belt. As an example, these cutting means 56 include an active vertical lowering guillotine on the dough belt positioned in correspondence of the guillotine itself, or else a cross cutting wheel operating on the dough belt.
    [0063] In the preferred embodiment, the advancement means 10 is controlled intermittently, such that the dough belt advances intermittently. In other words, the advancing means 10 is active (moving) during a first time interval and is inactive (stopped) during a second time interval following the first. During the operation of the machine 1 these time intervals follow each other consecutively.
    [0065] In this way, the cutting means 56 act on the unwound dough tape during the second time interval, that is when the advance means 10 is inactive and the dough belt is stopped. E so enables precise cutting of the dough belt to form dough strips 9.
    [0067] Each of the dough strips 9 develops along its own longitudinal development direction between two opposite extremities.
    [0069] After the cutting station 7, each of the dough strips 9 is conveyed by the advancing means 10 to the wrapping station 8. In particular, the advancing means 10 conveys a dough strip 9 at a time along along the formation path F, in such a way as to keep the dough strips 9 spaced from each other.
    [0071] In correspondence of the wrapping station 8, each of the dough strips 9 is wrapped in a food product 19 to form an edible roll 4 that extends along its own axis 200 of development between two opposite ends 4a, 4b .
    [0073] In the preferred embodiment, the wrapping station 8 includes a positioning zone 11 of the dough strip 9 and a winding area 12 of the dough strip 9 in the food product 19.
    [0075] In other words, the forming member 3 presents the positioning area 11 of the dough strips 9 and the winding area 12 of the dough strips 9. In fact, in the positioning area 11 the dough strips 9 are positioned correctly for wrapping, which is done in winding zone 12.
    [0077] In detail, the advancing means 10 includes a first positioning belt 13 and a second positioning belt 16 arranged after the first positioning belt, according to the formation path and operatively connected between them. In other words, the forming member 3 includes a first positioning belt 13 and a second positioning belt 16. Even more in detail, the first positioning belt 13 and the second positioning belt 16 are operatively connected to each other in correspondence of the positioning zone 11 of the dough strips 9.
    [0079] Furthermore, the first positioning belt 13 runs longitudinally along its own direction of advance 14, from the cutting station 7 to its own end discharge 13a. The second positioning belt 16 runs along its own direction of advance 15, from its own loading end 16a to the winding zone 12.
    [0081] Specifically, the advance direction 15 of the second positioning tape 16 is inclined with respect to the advance direction 14 of the first positioning tape 13. Even more specifically, the projections of the advance direction 15 of the second tape of positioning 16 and of the direction of advance 14 of the first positioning belt 13 in a horizontal plane are inclined between them by a predetermined angle.
    [0083] Preferably, this predetermined angle is substantially variable and adjustable depending on the demands. In any case, this angle is preferably different from 90o, in order to allow the successive spiral wrapping of the dough strip 9.
    [0085] In other words, the first positioning belt 13 and the second positioning belt 16 run along advance directions 14, 15, inclined to each other so that each of the dough strips 9 in the passage from the first positioning tape 13 to the second positioning strip 16 is arranged on the second positioning tape 16 obliquely with respect to the direction of advance 15 of the second positioning tape 16.
    [0087] Furthermore, the two positioning tapes 13, 16 are out of phase with each other. Precisely, the first positioning tape 13 is, at least in part, superimposed on the second positioning tape 16, so that, during use , each of the dough strips 9 passes from the first positioning tape 13 to the second positioning tape 16 by fall (figure 2).
    [0089] In other words, the discharge end 13a of the first positioning belt 13 is superimposed on the loading end 16a of the second positioning belt 16, so that, during use , the dough strip 9 is discharged by gravity from the discharge end 13a of the first positioning belt 13 to the loading end 16a of the second positioning belt 16. In this way, since the advance directions of the two positioning belts are inclined between them, the direction of development of the dough strip 9, after unloading it on the second positioning 16 is inclined with respect to the direction of advance 15 of the second positioning tape 16.
    [0091] Precisely, the direction of development of the dough strip 9 is inclined with respect to the direction of advance 15 of the second positioning belt 16 of the same predetermined angle of inclination between the direction of advance 15 of the second positioning belt 16 and the direction of advance 14 of the first positioning tape 13.
    [0093] Furthermore, the forming member 3 comprises synchronization means operatively connected to the first positioning belt 13 and to the second positioning belt 16 to coordinate them with each other. In detail, the synchronization means periodically control the stop of the second positioning belt 16 with respect to the first positioning belt 13 at the moment of the passage of each of the dough strips 9 from the first positioning belt 13 to the second positioning tape 16.
    [0095] In this way, an optimal positioning of the dough strip 9 is carried out on the second positioning belt 16.
    [0097] In fact, during use , the stopping of the second positioning belt 16 makes it possible to avoid displacements of the dough strip 9 falling thereon due to the movement of the second positioning belt 16 itself.
    [0099] By the term "optimal positioning" it is indicated that the direction of development of the dough strip 9 is inclined with respect to the direction of advance 15 of the second positioning belt 16 of the same predetermined angle of inclination between the direction of advance 15 of the second positioning tape 16 and the forward direction 14 of the first positioning tape 13.
    [0101] In detail, the synchronization means keep the second positioning belt 16 stopped until the dough strip 9 comes into contact with the second positioning strip 16.
    [0102] These synchronization means are preferably of the mechanical type and include a rotating toothed wheel that marks the timing of the periodic stop of the second positioning belt 16.
    [0104] In particular, the first positioning belt 13 and the second positioning belt 16 are independently motorized with respect to each other. In other words, each positioning belt is connected to a corresponding specific motor. T he timing means control the switching on and off of each specific engine.
    [0106] As already mentioned, after the positioning zone 11 a winding zone 12 is present for wrapping each of the dough strips 9 in the food product 19, to form an edible roll 4.
    [0108] Preferably, the advancement means 10 also extend in correspondence of the winding zone 12. Precisely, the winding zone 12 is positioned near the exit station 6.
    [0110] Specifically, the second positioning belt 16 of the advance means 10 extends in correspondence of the winding zone 12. This second positioning belt 16 defines a transport plane in which the dough strips 9 are positioned.
    [0112] Furthermore, the forming member 3 includes a wrapper 18, positioned in correspondence of the winding zone 12 to wrap each of the dough strips 9 in the food product 19. In other words, the wrapper 18 has been mounted on the frame 2 and has been positioned along the formation path F after the positioning zone 11. In yet other words, the wrapper 18 is located near the exit station 6.
    [0114] In particular, the wrapper 18 is suitable to receive a food product 19 at a time (figure 3a).
    [0116] This wrapper 18 includes at least one hooking member 21 mounted on the frame 2 and movable between an advanced position (Figures 4a and 4b) in which it retains the food product 19 and a rear position (Figures 3a and 3b) in which it releases the product food 19. In particular, the hooking member 21 is mobile along a direction substantially orthogonal to the formation path F and parallel to the transport plane.
    [0118] Still more specifically, the hooking member 21 is vertically spaced with respect to the transport plane, in order to keep, during the advanced position, the food product 19 raised with respect to the second positioning belt 16. Preferably, the wrapper 18 includes two hooking members 21 opposed to each other, between which, in use , the food product 19. In other words, the two hooking members 21 have been spaced apart along a direction substantially transverse to the path of formation F and substantially parallel to the plane of transport.
    [0120] In still other words, each of the hooking members 21 is positioned in correspondence of a corresponding end 19a, 19b of the food product 19. In detail, the hooking members 21 are brought closer to each other in the advanced position and away from each other in the backward position.
    [0122] In this way, during the advanced position the latching members 21 retain the food product 19 by the ends 19a and 19b, while during the rear position the latching members 21 release the food product 19.
    [0124] As can be seen in Figure 3a, the forming member 3 includes two lateral supports 22 mounted in correspondence of the winding zone 12 to support the wrapper 18. Furthermore, the second positioning tape 16 has been positioned between the two lateral supports 22 and, during use , runs between them.
    [0126] As can be seen from the attached figures, each hooking member 21 includes a corresponding mandrel 23, rotatable about an axis of rotation 100. Preferably, each mandrel 23 is rotatable with respect to the same axis of rotation 100.
    [0128] Furthermore, each mandrel 23 is slidably mounted on a corresponding lateral support 22, so as to be able to run along a direction transverse to the formation path F and parallel to the transport plane. In detail, the sliding of the mandrel 23 along the direction transverse to the formation path F and parallel to the transport plane defines the advanced position and the rear position of the corresponding hooking member 21.
    [0130] Advantageously, each mandrel 23 includes a latch portion 24 projecting cantilever into the second positioning belt 16. Thus, the wrapper 18 includes two latch portions 24 which, during advanced position, retain the food product 19 .
    [0132] Preferably, each latch position 24 has a concave end 24a configured to partially envelop one of the ends 19a, 19b of the food product 19.
    [0134] In addition, the wrapper 18 includes rotation means 26 for rotating each mandrel 23 about the axis of rotation 100. Preferably, the means of rotation 26 allows rotation of the food product 19 about its axis 20.
    [0136] In the attached figures it is possible to see that the rotation means 26 include two pulleys 27, each one fitted in a corresponding mandrel 23 to put it in rotation. Furthermore, the rotation means 26 include a motor (not represented in the attached figures) connected to the pulley 27 through a belt 28.
    [0138] Note that, during advanced position, the axis of rotation 100 is coaxial to the axis 20 of the food product 19.
    [0140] Furthermore, the wrapper 18 is movable cyclically from the winding zone 12 to a release zone 57 of the food product 19. Precisely, the release zone 57 of the food product 19 is located after the winding zone 12.
    [0142] Furthermore, the release zone 57 is located in correspondence of an exit belt 37. In detail, this exit belt 37 extends after the winding zone 12 between a proper entry end 37a and a proper exit end 37b. In other words, the inlet end 37a of the outlet belt 37 has been positioned between the winding zone 12 and the release zone 57 of the food product 19. Again in other words, during use , after winding, the edible roll 4 is released onto the outlet belt 37.
    [0143] As it is possible to see in the attached figures, the side supports 22 are mounted in a sliding manner on the frame 2, in order to bring the wrapper 18 from the winding zone 12 to the release zone 57. Specifically, the Frame 2 includes two rods 29 arranged parallel to the formation path F, each one in correspondence of a corresponding lateral support 22. In addition, each lateral support 22 has a sliding hole 30 where a corresponding rod 29 has been inserted (figure 3a).
    [0145] The machine 1 includes a food product dispenser 19, preferably a hopper 31 arranged superiorly to the winding zone 12 and presenting a counter-profiled opening to a food product 19 for the exit by gravity of a food product 19 at the same time towards the zone winding. The hopper 31 has been mounted in correspondence of the release zone 57.
    [0147] Preferably, the hopper 31 is superiorly mounted to the tape exit and I os latch members 21, so that I will fall into the food 19 products wrapper 18, positioned corresponding to the release zone 57 by gravity. In this way, during use , each food product 19 descends from the hopper 31 into the wrapper 18 and is engaged by the wrapper 18 itself.
    [0149] In fact, after winding the dough strip 9 around the food product 19, the wrapper 18 is brought from the winding zone 12 towards the release zone 57. During the movement of the winding zone 12 to the release zone 57, the wrapper 18 at first releases the edible roll 4 and at a second time, following the first, hooks a new food product 19. Then the wrapper 18 returns from the release zone 57 to the winding zone 12 (figure 4a, 4b).
    [0151] The machine 1 includes at least one adhesion member 32 positioned in correspondence of the release position to assist, in use , the initial wrapping of the dough strip 9 in the food product 19.
    [0153] The wrapping of the dough strip 9 in the food product 19 is made in a spiral, for example from the first end 19a to the second end 19b.
    [0155] The adhesion member 32 preferably includes a lifting roller 33 operatively associated with the wrapper 18, to allow the dough strip 9 to rise over the product food 19. In addition, the rising roller 33 is motorized to rotate on itself in the opposite direction to the direction of advance 15 of the second positioning belt 16.
    [0157] Precisely, the rising roller 33 defines a proper surface of contact with the dough strip 9. This contact surface, in correspondence of a proper part closest to the second positioning belt 16, advances in the opposite direction to the direction of advance 15 of the positioning belt 16. Specifically, this lifting roller 33 is positioned in correspondence of a hooking member 21. Even more in detail, the lifting roller 33 is positioned after the winding zone 12 to raise, in use , the dough strip 9 on the food product 19.
    [0159] As it is possible to see in the attached figures, the adhesion member 32 also includes a bending roller 58 and operatively associated with the rising roller 33, to invite the dough strip 9 to be wound around the food product 19. Preferably, the Curl roller 58 is motorized and rotates in the same direction as rise roller 33.
    [0161] In particular, the bending roller 58 is arranged superiorly with respect to the rising roller 33, so that the dough strip 9, after being raised through the rising roller 33, comes into contact with the rising roller. Bend 58. In other words, bend roll 58 is further spaced from advancing means 10 with respect to rise roll 33.
    [0163] Preferably, the rising roller 33 and the bending roller 58 are positioned in correspondence of the first end 19a of the food product 19 to favor the initial wrapping of the dough strip 9. Alternatively, a further adhesion member 32b can be provided in correspondence of the second end 19b of the food product 19, which can be structurally analogous to the adhesion member 32. The further adhesion member 32b can be operated as the adhesion member 32, depending on the inclination of the dough strip, or it can be left free to favor the closure of the dough casing.
    [0165] If necessary, the machine 1 can include one or more incision organs (not illustrated in the attached figures) positioned after the wrapper 18 and can be activated in the edible roll 4 to cut it in one or more established positions. (in correspondence of the extremities or in intermediate positions between the extremities). In particular, each incision member has been configured to cut only the dough layer 9 and not the inner food product 19. Preferably, and only by way of example, each incision member comprises a rotating disk, for example free, supported by gravity on the edible roll 4.
    [0167] The machine 1 comprises driving means 35, mounted on the frame 2 and defining a support plane for the edible roll 4, to carry it along an advance path 36.
    [0169] T he driving means 35 are in continuation of the second positioning belt 16. In other words, the drive means 35 are in continuation of the advancing means 10. Again in other words, the drive means 35 are mounted after the advance means 10, along the formation path F. Furthermore, the advance path 36 is in continuation of the formation path F. Preferably, the advance path 36 has a rectilinear development.
    [0171] Preferably, the driving means 35 includes an exit belt 37, to bring the edible rolls 4 from the winding zone 12 to a closing zone 38 positioned after the winding zone 12. Precisely, the exit belt 37 is developed starting from the winding zone 12 to the entire closing zone 38. In other words, the exit belt 37 runs from the exit station 6 of the forming member 3 to the entire closing zone 38.
    [0173] According to the present invention, the machine 1 includes a closing member 39 mounted on the frame 2 and developing along the advance path 36, at least one own first passage section SI of the edible roll 4 and one own second section of passage S2 of the edible roll 4.
    [0175] Specifically, the second passage section S2 has a width, measured transversely with respect to the advance path 36 and parallel to the bearing plane, lower relative to the width, measured transversely with respect to the advance path 36 and parallel to the plane of support, of the first passage section SI, in order to close by contact the ends 4a, 4b of the edible roll 4.
    [0176] Even more specifically, the closing member 39 includes a pair of side gates 40 that rise from the support plane and have been mounted on the frame 2 in correspondence of the conduction means 35. In figure 5a it is possible to see that these gates 40 develop transversely with respect to the support plane.
    [0178] Furthermore, the side gates 40 are spaced from each other to define between them, along the advance path 36, the first passage section SI and the second passage section S2.
    [0180] As can be seen in Figure 5b, each side gate 40 includes its own narrowing portion 41 that develops from the first passage section SI towards the second passage section S2. This narrowing portion 41 defines a plane inclined with respect to a vertical plane. In particular, the inclined planes defined by the narrowing portions intersect after the closure member 39, along the advance path 36.
    [0182] Furthermore, the constriction portion 41 develops along the advance path 36 from a first proper end 41a to a second proper end 41b. The first passage section SI is defined by the distance between the first extremities 41a of the corresponding narrowing portions. The second passage section S2 is defined by the distance between the second extremities 41b of the corresponding narrowing portions 41.
    [0184] Each side gate 40 further includes a rectilinear portion 42 connected to the constriction portion 41 and thereafter along the advance path 36.
    [0186] This rectilinear portion 42 of the side gate 40 is substantially transverse to the bearing plane and substantially parallel to the advance path 36. Specifically, the distance between the rectilinear portions 42 of the side gates 40 is substantially constant along the advance path. 36, where this distance is measured transversely with respect to the advance path 36 itself. Furthermore, the distance between the rectilinear portions 42 of the side gates 40 is equal to the second passage section S2.
    [0187] Therefore, the second passage section S2 extends along the entire length of the rectilinear portions 42.
    [0189] Finally, each side gate 40 includes a widening portion 43 connected to rectilinear portion 42 and positioned after it. The widening portions of the side gates 40 together define a widening of the passage section, measured transversely to the advance path 36 for the exit of the edible roll 4 from the closing zone 38.
    [0191] Preferably, the narrowing portion 41, the rectilinear portion 42 and the widening portion 43 together form a single body (Figure 5b).
    [0193] The machine 1 further includes regulation means 44 active between the side gates 40 to bring them closer and / or move them away from each other, in order to regulate the width of the first passage section SI and the width of the second passage section S2.
    [0195] Preferably, these adjusting means 44 include at least one screw 45 for each side gate 40. Each screw 45 is screwed into the support frame 2 and abuts the side gate 40.
    [0197] Advantageously, each side gate 40 is slidably mounted on the frame 2 and is movable along a direction substantially perpendicular to the advance path 36 to widen or narrow the first and second passage sections S2. In this way, by screwing or unscrewing the screws 45 of the adjustment means 44, the width of the passage sections is adjusted.
    [0199] Specifically, by screwing in screws 45 the width of the first through section SI and of the second through section S2 decreases, while by unscrewing screws 45 the width of the first through section SI and of the second through section S2 increases .
    [0201] In the preferred embodiment described, for example, in figure 5b, the adjustment means 44 include two screws 45 for each side gate 40. These screws 45 are arranged one after the other along the advance path 36 , in order to stabilize the corresponding side gate 40.
    [0202] Furthermore, the side gates 40 are spaced from each other and the conduction means 35 are arranged, at least in part, between them. Precisely, between the gates is arranged, at least in part, the outlet belt 37.
