    [0001]
    [0002]
    [0003]
    [0004] The present invention relates to a product cutting equipment, preferably of frozen food products, where the cutting is carried out by a band saw cutting system, preferably operating in an automatic way of passing the product through the system of cutting, although it can also be used in a manual mode of product movement.
    [0005]
    [0006] Background of the invention
    [0007]
    [0008] They are known and, therefore, are in the state of the art, the equipment for cutting products that have a bandsaw for cutting said products, where said bandsaw is usually operated by a system of motorized pulleys in which the bandsaw is installed. The bandsaw is guided and tensioned to prevent its exit from the position chosen at the time of the cut in which the product exerts a force on said bandsaw.
    [0009]
    [0010] By rotating the pulleys, the band saw is rotated at the speed of said pulleys, so that by means of a serrated side on the side of the band saw where the product to be cut enters, the cutting of said pulley can occur. product that is pushed in that direction, towards the serrated side of the bandsaw.
    [0011]
    [0012] To cut the product, it must be replaced in the front part of the bandsaw, to pass it through the saw and cut a new portion of the product. Thus, for each new cut that you want to make in the product, said product will make a return movement to the starting position of cutting in addition to the movement itself through the bandsaw, with which there are unproductive movements and time of the machine cut.
    [0013]
    [0014] Double-serrated band saws are also known, which allows them to cut on both sides, being able to perform cutting both ways, but which cannot be guided in the cutting plane, having saw teeth on both sides and not being able to counter the thrust of the product when pressed against the saw belt to make the cut. This lack of guidance causes a lack of security of the position of the band saw, which may affect the accuracy of the product cut, as well as a possible exit of the belt saw itself from the pulley system and therefore its malfunction.
    [0015]
    [0016] Description of the invention
    [0017]
    [0018] With the band saw cutting equipment of the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described.
    [0019]
    [0020] The present invention is based on a cutting equipment based on cutting by band saws, whereby the equipment has the usual pulley systems for the movement of said band saws.
    [0021]
    [0022] Advantageously, the cutting equipment contains at least one cutting system formed by two individual band saws contiguously located without touching each other, both in the same cutting plane, with said separation between both individual band saws , each of said two band saws having a single side with cutting teeth located in the opposite edges farther between both band saws, so that, when cutting a product and passing it through said band saws in any direction, the first edge they find will be toothed to make the product cut, while the closest inner edges between saws will not have cutting teeth.
    [0023]
    [0024] The pressure on the band saws exerted by the passage of the product, usually causes the movement of said band saws in the same cutting plane, especially if they are frozen products, causing a possible contact of a saw against the other and , therefore, its possible deterioration, or it could make the band saws flex in the perpendicular plane, having different product measures cut. Therefore, the cutting system of the equipment described in the present invention has at least one guide and separation piece of both band saws, preferably having two to four of said guide and separation pieces installed, where the piece of separation is fixed in a position that guides each of the band saws in the cutting plane, preventing it from flexing easily and leaving said plane by guiding elements. In the same way, said guide and separation piece keeps both band saws separated in the cutting plane by means of a minimum separation element.
    [0025] The placement of said guide and separation pieces allows minimizing the risk of the saws coming out of their position in the pulley system in which they rotate due to the pressure action of the product to be cut, which will preferably be placed on both sides of the cutting zone, between said zone and the next or previous pulley so that the pressures in said zone do not affect the correct passage of the band saws through the pulleys. This configuration of a separation piece on either side of the cutting area can be reinforced by the placement of more pieces on one and / or other side of the cutting area.
    [0026]
    [0027] The separation between the band saws of the cutting system is introduced as a stop of the displacement of the band saw that receives the pressure of the product to be cut in the direction of cut and to avoid the exit of its pulley wheel, as well as to avoid the contacts between said band saws by their non-serrated inner edges, having the minimum distance of the separation element is preferably less than 30 mm, and more preferably to make it minimum, between 2 mm to 6 mm, so that, maintaining said distance between they, a superior separation could not give problems to the passage of the product to be cut by the second band saw, since said product could be turned towards said second cutting saw, although with separate systems of the cut product, superior separations could be had.
    [0028]
    [0029] The products to be cut are preferably passed automatically by means of a grip and displacement system of said product to be cut. The product can be of different dimensions so that the cutting area of the band saws can be more or less wide. With this, to keep the cutting plane as fixed as possible, preferably, the cutting equipment has at least two pieces of guidance and separation of both band saws, each of them being located on each side of the area of cutting the product, being able to regulate the height of the position of at least one of the two pieces of guidance and separation that define the cutting area through which the product passes.
    [0030]
    [0031] The cutting equipment can incorporate, preferably in its automatic mode of use, a protective system of the band saws formed by an enveloping structure of said band saws that automatically moves to cover the cutting area when an operator enters the zone of protected influence, with the aim of preventing the operator from accidentally introducing any part of his body in the cutting area or that a breakage of the bandsaw at that time can leave farewell and affect him, in addition to protect the bandsaw itself from possible incidents of the materials carried by the operator.
    [0032]
    [0033] Also preferably, the cutting equipment has a cleaning system for the band saws which eliminates the possible substances or residues of the cut of the product that can usually accumulate in the cutting teeth, being able to reduce the effectiveness of said cutting.
    [0034]
    [0035] The cutting equipment can be configured so that, in a homologous way to what is indicated above, the cutting systems available in the same equipment are multiplied, being able to make simultaneous cuts in parallel planes, having two or more cutting systems that make said cuts in parallel planes.
    [0036]
    [0037] This advantageous configuration in two band saws per cutting system installed in the cutting equipment, improves the productivity of the cutting systems with a single cutting saw with a single cutting edge and, therefore, with a single direction of cutting and the need to make displacements of the product to be cut that are unproductive, solving this with the two cutting directions that are possible in the present invention, having the cutting edges of each of the opposite band saws, on the external parts of each band saw, considering the outer part of each one of them as the edge furthest from the other band saw.
    [0038]
    [0039] In the same way, said novel configuration solves the problem of the single band saws with the two serrated cutting edges that, allowing two-way cutting, prevent their clamping against pressures in the same cutting plane, having problems of malfunction , which is minimized with said configuration of two band saws per cutting system, with their corresponding guide and separation pieces that act by retaining the possible displacement of the band saws when the product to be cut is pressed on them, being able to way, for example, to cut frozen food products.

    [0057] Description of a preferred embodiment
    [0058]
    [0059] In the present preferred embodiment of the invention, and as shown in Figures 1 to 6, the cutting equipment (10) has to be made by means of a bandsaw of products, in this case frozen food products, is based on a cutting system that has two individual band saws (11, 11 '), contiguous without touching, having said band saws (11, 11') in the same cutting plane (P), mounted on the same wheel of pulley (12) with double channel / rail, where alternatively, they could be mounted on a double wheel pulley system with single channel / rail each, being able to be independent pulley systems assembled together, with said separation between band saws (11, 11 ').
    [0060]
    [0061] Band saws (11, 11 ') are characterized by having a single cutting edge (15), being positioned so that the inner edges (14) are without cutting teeth, but with the opposite outer edges (15) are toothed to have the possibility of cutting and, of this In this way, the product to be cut can be passed in one direction or another indifferently, and the product can be cut in both directions, without having to make an extra displacement of the product until the start of the equipment to make the cut in the same sense. The outer edge (15) is the part of the band saw that is furthest from the other band saw, while the inner edges (14) are the closest edges between them of each band saw (11, 11 ') .
    [0062]
    [0063] Said belt saws (11, 11 ') are separated by a distance of less than 6 mm, preferably from 4 mm to 5 mm, separation which is achieved in the first instance by the separation between the channels / rails of the pulley wheel ( 12). In alternative embodiments, minimum separations of 2 mm are reached to avoid risks of contacts between saws (11, 11 ’). By introducing auxiliary elements such as separators of the cut product or the like, one could have superior separations.
    [0064]
    [0065] As the band saws (11, 11 ') are subjected to a pressure caused by the passage of the product to be cut on said band saws (11, 11'), these (11, 11 '), although they are tensioned to perform their rotation between the pulleys (12) and avoid varying their cutting plane, they can tend to move in the same cutting plane in the same direction of advance of the product to be cut by its pressure against them, which could cause to exit the rail / pulley channel (12) or impacting the band saw (11), first to make the cut, against the adjacent band saw (11), being able to make them contact each other, which could imply deterioration of said band saws (11, 11 '). In the same way, the friction of cut of the band saws (11, 11 ’) on the product can cause that according to the material to be cut, there are forces perpendicular to the cutting plane that can cause cuts of non-regular thicknesses.
    [0066]
    [0067] The cutting equipment (10) includes, in the present embodiment, two pairs of guiding and separating parts (16, 16 ') fixed to the cutting equipment (10) defining between each pair (16, 16') an area of cutting (Z), guiding the passage through said pairs of pieces (16, 16 ') of each of the band saws (11, 11') to minimize variations of the cutting plane between said two pairs of pieces (16, 16 ') and physically separating them so that even if there is such pressure, they do not come into contact with each other (11, 11').
    [0068]
    [0069] Alternatively to this and other possible embodiments, a single pair of guiding and separating pieces, a piece on each side of the cutting area, or a only piece of guidance and separation in the cutting system that performs said function in the area near the cut, preferably. You can also have more guide pieces according to the configuration of the cutting area that is necessary and the expected characteristics of resistance to the cut of the product, preferably grouped in pairs on one side and another of the cutting area.
    [0070]
    [0071] Each of guiding and separating pieces (16, 16 '), as can be seen in Figure 3, are formed by a body which, in the present embodiment, is composed of at least tungsten carbide, having a high wear resistance, so that materials with a wear-resistant resistance could be used in the same way, such as graphite thermal plastics, ceramic materials or other special plastics. This guide and separation piece has a groove (17), as a guiding element, for each of the steps to guide each bandsaw (11, 11 '), with dimensions slightly greater than those of thickness and Achura of said band saws (11, 11 ') with what pressures against them that are in the plane perpendicular to the cutting, are prevented by said guided by the grooves. In the same piece there is a separation (18) between the grooves (17), as a separation element, which corresponds to the minimum separation that you want to have between the two band saws (11, 11 ') and which prevents the displacement of the bandsaw (11, 11 ') that receives the pressure of the product when cutting, in the cutting plane in the direction of cutting.
    [0072]
    [0073] In alternative embodiments, the guide and separation piece can be, instead of in one piece, in separate guide and separation bodies.
    [0074]
    [0075] Alternatively, the guide and separation piece can be made with bearings, not shown in the figures, instead of contact surfaces of the tungsten carbide body, based on a pair of facing bearings, as a guiding element. , which leave a separation between them slightly greater than the width of the bandsaw (11, 11 '), and as a separating element of the guide and separation piece there would be one or more bearings between both band saws (11, 11 ') that maintain a minimum distance between said saws (11, 11').
    [0076]
    [0077] In the present embodiment, there is an upper guide and separation part (16) that is height adjustable, in order to define a variable cutting area (C) between the two guide and separation parts (16, 16), where the lower part (16 ') is fixed next to the platform where the product to be cut is moved.
    [0078]
    [0079] Alternatively, the guide and separation pieces can all be fixed or adjustable all of them, to have different configurations of the cutting equipment (10).
    [0080]
    [0081] The cutting equipment (10), in the present embodiment of use in automatic mode by moving the product by an automated grip and displacement device, includes a protective system (20) of the band saws (11, 11 ') with automatic movement at the moment in which the entrance of an operator is detected in the associated safety enclosure of the cutting equipment. This protective system (20) is formed by an enveloping structure of said band saws (11, 11 '), which at the time of detecting the entry of the person in the security area, moves said structure to the cutting area , minimizing the possibility of damage if there was a break in said band saws (11, 11 ') and preventing an operator from accidentally accessing the cutting area.
    [0082]
    [0083] As another auxiliary element, and as can be seen in Figure 6, the cutting equipment (10) includes a cleaning system (19) of the band saws, where said cleaning system (19) is formed by the action of brushes which are located on the side and side of the bandsaw (11, 11 ') and have an elastic system so that as the brush is spent it is supplied, approaching, the bandsaw (11, 11') and that any impact / contact on said brush by the bandsaw (11, 11 ') is absorbed by the elastic system, preferably springs.
    [0084]
    [0085] As an alternative configuration that would comprise the previous elements of the main commented embodiment and its commented alternatives, it is necessary that the cutting equipment (10) has two or more cutting systems that make cuts in parallel planes, for the same product step , that several cuts can be made at the same time.
    [0086]
    [0087] Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the band saw cutting equipment is susceptible to numerous variations and modifications, and that all the mentioned details can be substituted. by others technically equivalent, without departing from the scope of protection defined by the appended claims.
