    [0003]
    [0004] Sector of the technique
    [0005]
    [0006] The present invention is related to the machines used to cut food and more specifically to a machine that allows to cut with precision food such as cakes, pies or similar.
    [0007]
    [0008] State of the art
    [0009]
    [0010] The use of water jet cutting technology has spread in the bakery, pastry and confectionery food sector due to its versatility and ease of use. The use of water for cutting food is an improvement over conventional cutting systems using blades. By not using blades no time is lost in changing or sharpening them, in addition this technology is a method of hygienic cutting and without bacteria as it eliminates the risk of contamination associated with the use of blades.
    [0011]
    [0012] Food cutting machines such as cakes, pies or the like have a water jet cutting head and a tray on which the food to be cut is arranged. The cutting head is arranged on the free end of a movable arm that is movable on the food to describe on it the cutting paths that are required.
    [0013]
    [0014] With this embodiment the cutting head is a cantilevered element on which unwanted moments of inertia appear which cause an imprecise cutting of the food, which affects the quality of the final product obtained. This is a significant problem in products such as cakes, pies or similar products where the aesthetic finish of the product is a relevant factor in its sale.
    [0015]
    [0016] On the other hand, the movement of the cutting head is done by virtue of a system of drive in two dimensions XY built with linear guides, belts, spindles in sight, or other mechanical elements not suitable to be in a zone of passage of food . Frequently these elements are very close to food, being able to contaminate the product to be cut with lubricants, residues of cleaning products, residues caused by the friction of mechanical elements, or other elements that could not be eliminated in the washing process. Additionally, not all elements are always stainless or resistant to aggressive cleaning products.
    [0017]
    [0018] In other embodiments of the machine, the cutting head remains still, and it is the tray with the food that moves under the head. In this case, the cutting speed and precision are penalized by the inertia of the food, causing movement of the food on the tray, slipping, falling of cut pieces and inaccuracies, limiting the achievable accelerations and therefore increasing the cycle time of the food. each cut.
    [0019]
    [0020] Therefore, an alternative solution is necessary to improve the precision of water jet cutting machines that use mobile arms to carry the cutting head and at the same time comply with the highest cleaning standards.
    [0021]
    [0022] Object of the invention
    [0023]
    [0024] The invention has for its object a food cutting machine by means of a pressurized water jet comprising:
    [0025]
    [0026] • a tray on which a food to be cut is available,
    [0027] • a pressurized water jet cutting head,
    [0028] • a first extendable arm having a fixed end articulated in free rotation with respect to the machine and a free end in whose proximity the cutting head is disposed, and • a second extendable arm having a fixed end articulated in free rotation with respect to to the machine and a free end, wherein the free end of the second extendable arm is joined by a joint to the free end of the first extendable arm.
    [0029]
    [0030] According to an example of a preferred embodiment of the invention, the cutting head is arranged in the articulation of the free ends of the extendable arms, whereby the weight of the cutting head is correctly distributed between both extendable arms.
    [0031]
    [0032] Each extendable arm comprises a movable part attached to a translating carriage which is movable on a guide defined in the lower part of a housing where it is partially hosted the mobile part.
    [0033]
    [0034] The transfer carriage carrying the moving part is driven by a nut-screw mechanism comprising a threaded shaft that engages in a nut defined in the carriage of translation.
    [0035]
    [0036] The threaded shaft of the nut-spindle mechanism is coupled to a motor by means of a drive belt.
    [0037]
    [0038] The transmission belt is arranged in a cylindrical polished stainless steel housing.
    [0039]
    [0040] The machine additionally comprises lifting means for jointly actuating the extendable arms thus regulating the distance between the cutting head and the tray.
    [0041]
    [0042] With all this, a food cutting machine is obtained by means of a pressurized water jet where the cutting head is adequately supported by the extensible arms, attenuating the moments of inertia that appear during the displacement of the head during cutting. In addition, the cleaning conditions in the machine are improved since the drives of the extendable arms are located outside the cutting zone where the food is placed.
    [0043]
    [0044] Description of the figures
    [0045]
    [0046] Figure 1 shows a perspective view of the food cutting machine of the invention.
    [0047]
    [0048] Figure 2 shows a perspective view of the extendable arms of the machine represented in the previous figure.
    [0049]
    [0050] Figure 3 shows a partial section view of the mechanisms of action of one of the extendable arms.
    [0051]
    [0052] Detailed description of the invention
    [0053] Figure 1 shows a food cutting machine by pressurized water jet according to the invention. The machine comprises a frame (1) and a hinged lid (2) arranged in the upper part of the machine that gives access to the cutting area where the food (3) is arranged.
    [0054]
    [0055] The cutting area has a tray (4) on which are available the food (3) to be cut and two extensible arms (5,6) that support a cutting head (7) by pressurized water jet.
    [0056]
    [0057] Preferably the tray (4) is removable to be able to better load the food (3) to be cut. The tray (4) can be constructed with mesh or with a bed of blades to allow the passage of water during cutting.
    [0058]
    [0059] The first extendable arm (5) has a fixed end (5.1) that is articulated in free rotation with respect to the frame (1) of the machine and a free end (5.2) in whose vicinity the cutting head (7) is arranged, while the second extendable arm (6) has a fixed end (6.1) that is also articulated in free rotation with respect to the frame (1) of the machine and a free end (6.2), with the free end (6.2) of the second extendable arm (6) joined by means of a joint (8) to the free end (5.2) of the first extendable arm (5).
    [0060]
    [0061] In this way, the extensible arms (5, 6) are arranged in the cutting area with a "V" shaped configuration joined together by their free ends (5.2, 6.2) and joined in free rotation to the machine by its fixed ends (5.1.6.2) and the cutting head (7) is arranged in the vicinity of the union of the free ends (5.2, 6.2) of the extendable arms (5,6) so that a configuration of the arms (5,6) more rigid than the solutions of the state of the art improving the precision and control in the movements of the cutting head (7).
    [0062]
    [0063] In this way it is achieved that the rotation of each one of the extensible arms (5,6) is activated by the extension or retraction of the other of the arms (5,6). In addition, this drive is applied at a significant distance from the axis of rotation of each arm (5,6) with respect to the frame (1), since the free ends (5.2, 6.2) of the arms (5,6) are applied, with which the precision of rotation obtained is of a higher range than that which would be obtained if the machine had the rotation of each arm (5,6) with respect to the frame (1) directly applied in the articulation of the fixed end (5.1.6.1) to the frame (1).
    [0064]
    [0065] According to the embodiment shown in FIGS. 1 and 2, the cutting head (7) is arranged in the articulation (8) of the free ends (5.2, 6.2) of the extendable arms (5.6), with which the stability is improved of the cutting head (7), although this provision is not limiting, the cutting head (7) being able to be arranged in a location different from the articulated joint of both arms (5,6), as for example in an extension of the free end (5.2, 6.2) of the first (5) or second extendable arm (6).
    [0066]
    [0067] Figure 3 shows an example of embodiment of one of the extensible arms (5,6), the embodiment of the other of the extensible arms (5,6) being identical. The extendable arm (5.6) comprises a mobile part (9) that is attached to a transfer carriage (10) that is disposed inside a housing (11) where the mobile part (9) is partially housed. In the lower part of the casing (11) is defined a guide (12) on which the translating carriage (10) carrying the mobile part (9) is movable.
    [0068]
    [0069] The movable part (9) has at its free end the articulation (8) where the cutting head (7) is located, said free end corresponding with the free end (5.2.6.2) of the extendable arm (5,6).
    [0070]
    [0071] The translation carriage (10) is driven by a nut-spindle mechanism comprising a threaded shaft (13) which engages in a nut defined on the translation carriage (10), so that the rotation of the threaded shaft (13) causes a linear displacement of the translation carriage (10) on the guide (12) in the direction represented by the arrow (A).
    [0072]
    [0073] Preferably the nut-spindle mechanism is a ball screw because of the high speeds of rotation that it will reach during work.
    [0074]
    [0075] The threaded shaft (13) is coupled to a drive motor (14) by means of a drive belt (15).
    [0076]
    [0077] The transmission belt (15) is housed inside a cylindrical casing (16) made of polished stainless steel that has sealing gaskets to ensure that the transmission debris can contaminate the cutting zone. Both the housing (11) and the cylindrical housing (16) are elements that can be easily cleaned without leaving residues that can contaminate food.
    [0078]
    [0079] Preferably both extendable arms (5,6) are independently driven by a respective motor (14), so that by controlling the linear displacement of the moving parts (9) of both arms (5,6) the trajectories carried out are controlled the cutting head (7) on the food (3).
    [0080]
    [0081] The union in turn, represented by the arrow (B) in the figures, between the fixed ends (5.1, 6.2) of the extensible arms (5,6) and the frame (1) of the machine is free, so that only the linear drive of the moving parts (9) of the arms (5,6) is required for the displacement of the cutting head (7) on the work surface.
    [0082]
    [0083] The machine additionally comprises lifting means that allow to act jointly both extendable arms (5,6) to regulate so the distance between the cutting head (7) and the tray (4), so that the machine can be adapted to food (3) of different heights.
    [0084]
    [0085] It is provided that the tray (4) on which the food (3) is arranged is static and that the extension arms (5,6) are configured to reach any point on the surface of the tray (4), although the The tray (4) can be moved by means of a suitable actuating means, so that the tray (4) can make movements of approach and distance with respect to the cutting head (7), with which the extensible arms (5,6) they can be dimensioned with a smaller size to perform the movements in the direction (A). In addition, the combined displacement of the tray (4) and the cutting head (7) allows obtaining an optimum distribution of the accelerations between both elements,
    [0086]
    [0087] Additionally, the machine comprises a mobile drain for the evacuation of the water used for cutting the food (3), said drain being composed by a mobile tube that moves in a horizontal plane following the movements of the cutting head (7).
