Definitions

• the present invention relates to a device for folding a sheet of food material filled with a filling so as to form an edible package with the latter.
• It relates, more particularly, to a device for packaging a food filling by means of industrial folding of a sheet of food material of the pancake, rice pancake and other type, surrounding said filling.
• the object of the invention is to provide a device for industrial folding of the food sheet which is simple to produce and inexpensive.
• the subject of the present invention is a device allowing the folding of a sheet of food material filled with a filling so as to form an edible packaging with the latter, conveyed by means of a conveyor belt, characterized in that that it consists of at least one folding means able to grasp one of the edges of the sheet and to simultaneously impulse a movement opposite to the movement of movement of the rear part of the sheet.
• the folding means consists of a motorized roller capable of gradually and successively taking a first position in which said roller is located in the extension of the belt and a second position in which the roller is in elevation relative to to the parallel plane of the mat.
• the aforementioned roller is provided with a simple helical groove or with several threads with the rounded top thus minimizing the contact surfaces between the food material and the roller.
• the device consists of a first means of folding the upstream part of the food material
• the device consists of at least a pair of means for folding the sides of said material, and a conveyor belt
• the first folding means consists of a motorized roller capable of gradually and successively taking a first position in which said roller is located in the extension of the belt and transverse to the latter and a second position in which the roller is elevated from the parallel plane of the mat
• the pair of folding means consists of two motorized and movable rollers interposed in the rest position in the conveyor belt, these rollers being arranged in the longitudinal direction of the conveyor belt
• each of the rollers is capable of describing a circular arc movement in the direction of the opposite roller in a plane transverse to the direction of movement of the sheet of material and this in a phase shifted with respect to the 'other
• the device comprises a means of rolling the sheet of food material which is constituted by two superimposed belts spaced from one another, one of which is movable relative to the other
• FIG. 1 is a schematic view of the folding device according to the present invention.
• upstream of the device (1) is arranged a conveyor belt (4) for feeding sheets of food material (2) having, for example the general shape of a circle and a depositing means (5) d 'a volume of filling on said sheets of material (2), the consistency of which may be solid, grainy or pasty.
• Downstream of the device (1) is arranged a second conveyor belt (10) intended to evacuate the sheets of food material (2) filled with their filling (3) and folded.
• the folding device (1) consists, according to a preferred embodiment, of a first folding means (6) of the upstream part of the food material, of a pair of folding means (7 and 8) on the sides of said material, a conveyor belt (9) and a rolling means (10) of the assembly before it is removed by the second conveyor belt, not shown.
• the first folding means (6) consists of a motorized roller capable of gradually and successively assuming a first position in which said roller is located in the extension of the belt (4) and transverse to the latter, and a second position in which the roller is in elevation relative to the parallel plane of the belt.
• the roller (6) is supported, via its axis of rotation (A), by two parallel arms (1 1) capable of pivoting from a first position called rest, in which said roller (6) is located in the extension of the belt and transverse to the latter, to a second position in which the roller (6) is in elevation, as mentioned above.
• the pivoting movement is provided for example by a cam (12), or all types of actuators.
• the roller (6) is motorized in rotation by a set of belts (13) whose rotation is controlled by an electronic control unit, not shown, as a function of sensor signals, of the presence sensor type. the sheet of food material (2), through the device (1).
• the pair of folding means (7 and 8) consists of two motorized and movable rollers interposed in the rest position in the conveyor belt (9). These rollers are advantageously arranged in the longitudinal direction of the conveyor belt (9). Each of these rollers (7, 8) is suitable for describe a circular arc movement - or horizontal - in the direction of the opposite roller in a transverse plane relative to the direction of movement of the sheet of material (2) and this out of phase with respect to each other
• the above-mentioned folding means (7 and 8) may consist of several rollers arranged at variable angles relative to the belt
• each of the rollers (7, 8) is fixedly mounted to a movable arm (14) successively in a vertical direction directed upwards, as visible in the figure 2 (arrow B), then in an oblique direction (arrow C ) directed downwards so as to make each of the rollers (7, 8) describe the circular arc movement described above
• the mobility of each of the arms (14) is ensured for example by means of a system a set of cams (15) controlled in rotation by the electronic control unit, as a function of signals from sensors of the presence of the sheet of food material (2)
• This set of cams (15) advantageously allows phase shifting arm movements (14)
• each of the rollers (7, 8) is driven in rotation by a system consisting of sets of driven toothed wheels (16), connected together by a rod housed inside the arm (14) driven in rotation by a driving gear (17) able to cooperate successively with a first (18) and a second (19) rack fixed to a frame (20)
• the rollers (6, 7 and 8) constituting the folding means are arranged according to the needs linked to the phenomena of adhesions, in form reducing the contact surfaces, such as a simple helical groove or with several threads with , preferably, the rounded top or radial grooves performing the same function for the purpose and to avoid as much as possible the contact surfaces between the edible food material and the roll.
• this function can be carried out with a smooth roll on which one slides an elastic net or not thereby reducing the contact surface
• the pair of folding means (7, 8) is made up of two twisted lateral rotating belts.
• the rolling means consists of two superimposed belts spaced from one another, one of which is movable relative to the other.
• these carpets are made of stainless steel having the general shape of a coat of mesh, the mesh of the latter possibly varying according to the material of the sheet to be rolled.
• This sheet (2) filled with its lining (3) is then brought to the right of the first folding means (6).
• a presence detector not shown, transmits a signal to the control unit which transmits the order to drive in rotation, in the opposite direction of the movement of the carpet, the roller (6) as well as its progressive movement from its first so-called rest position in its second position thus folding the upstream part of the sheet (2) onto the lining (3).
• the downstream part is then driven by the conveyor belt (4) until it tips over the conveyor belt
• the conveyor belt (9) brings the sheet of material (2) to a certain position above the pair of folding means (7, 8).
• the control unit moves in a phase-shifted manner in time respectively each of the arms (14) in vertical direction (arrow B) upwards then obliquely (arrow C) downwards and concomitantly the rotation of the rollers (7, 8) thus successively producing a second and a third fold on the lining (3).
• Each of the arms (14) is returned to its initial position, FIG. 5, by means of actuators, not shown.
• the sheet of food material (2) thus folded is capable of being conveyed by the conveyor belt (9) between the space formed by the two movable arms (14) up to the rolling means (10).
• the sheet of food material hangs on the different meshes constituting the belts causing a winding and displacement thereof to the conveyor belt for discharging the sheet.
