    DISPENSER OF SHAPED PAPER SHEETS
    The present invention relates to a dispenser of pre-cut paper sheets, such as sheets of paper for towels or the like, which allows to obtain paper towels or napkins, and other similar elements, from a roll of paper or material Similar pre-cut. The invention allows delivery so that the amount dispensed is predetermined.
    10 The dispenser can be used in the sanitary sector for hand drying, in the industrial sector for surface cleaning, in the sanitary sector for the supply of toilet paper, in the catering sector for the supply of napkin paper, in the distribution sector for the packaging of objects, whether food or not, and in any sector that needs to obtain a certain amount of paper or similar material. STATE OF THE TECHNIQUE
    There are several types of roll paper dispensers with numerous patents.
    20 The most commonly used are devices that distribute the paper along its axis, called wick or chimney dispensers, whereby the paper is manually stretched from the inner axis of the roll that is in the vertical position. At the exit of the apparatus, a lateral force must be exerted to cut the paper with a serrated cutting surface. The drawback of this technique is that the paper is wrinkled and that the length of the paper dispensed is not
    25 determined previously but depends on the force applied by the user.
    With the roll in horizontal position there are other types of dispensers that can be summarized in three. The simplest is a lever dispenser, whereby an outer lever is operated so that an inner rack moves a pinion that supplies a quantity
    30 set of paper. This dispenser also requires that the paper be cut by exerting a lateral force, moving the paper against a saw-shaped blade.
    A second type of device solves the problem of the lever - which ends up being a point of bacteriological contagion among users - by automating the mechanism, 35 so that an engine supplies the fixed amount of paper, which in turn must be cut manually against a serreta outside the device. This second device solves the


    problem of user contact with the lever but it persists in manual cut mode once the amount of paper is supplied.
    Finally another device called "auto-cut" automatically cuts the paper in the form of a roll.
    5 For its operation, the paper is pulled outwards, an action that moves an inner rollerwhose development coincides with the determined amount of paper to be supplied. The roller hasa mobile blade that is the one that finally cuts the paper when it passes over another fixed blade.To overcome the cutting action, the tensile force charges a spring that will give up its energyright at the time of cutting. The design solves all dispenser problems
    10 lever and electric, so the paper supplied is always the same length, does not contaminate between different users and the paper is definitely cut.
    However, this third system introduces a new problem that is the resistance of the paper. Since the apparatus needs a cutting energy that accumulates with the force of extraction 15 of the paper, the resistance of the paper must be notoriously high. Moreover, the greatest use of this type of apparatus is for hand drying, and humidity reduces the resistance of the paper. Therefore, this type of apparatus is limited to the use of papers with a minimum weight that gives sufficient strength to move the internal drum and make the cut. Another option is to make a more moisture resistant paper, but it costs more. In addition to all this,
    20 This apparatus limits the use of low weights for the use of toilet paper or napkin paper, for example.
    Such a development uses pre-cut paper, so that the dispenser calculates the length of the precut and fixes the paper just at the moment where the paper should be cut. This last system consists of a roller with an encoder that calculates the length of the paper so that it drives one or two coils that fixes a tightening roller.
    Examples of prior art dispensers can be seen in US4186633A, US2003110911A1 and WO9322962A1. 30 DESCRIPTION OF THE INVENTION
    The objective of the present invention is to provide a pre-cut paper sheet dispenser that has the advantages described below. This dispenser 35 solves with its different embodiments the problems of the prior art.


    The roll-shaped pre-cut paper sheet dispenser comprises means for holding a roll of paper inside a housing. It includes means for cutting a sheet of pre-cut paper and means for holding one end of the paper on said roll after removing a sheet of pre-cut paper. In addition, the paper holding means comprise a pressure bar arranged and adapted to permanently contact the paper while the user pulls the paper to remove a sheet. Likewise, the cutting means comprise a cutting element provided on a support surface of the paper that is associated with said pressure bar. The sheets of paper are capable of being manually cut by said cutting element when the user modifies the direction of the paper in contact with a edge of said support surface while the paper remains tensioned by the pressure bar.
    The claimed device has the advantage of allowing the paper to be cut manually and efficiently by its pre-cut line using very few components. The pressure bar provides the minimum pressure and tension necessary for the user to make the cut only by modifying the direction of the paper in contact with the edge of the support surface.
    Preferably, the pressure bar is arranged and adapted to press a sheet of paper on an auxiliary support base, the paper being susceptible to run between said auxiliary support base and said pressure bar while the user pulls the paper to remove a sheet .
    According to a preferred embodiment, said auxiliary support base comprises a paper support roller that is arranged in the housing to cooperate with said pressure bar so that it receives a paper end from said roll. In another embodiment, said auxiliary base may be a support plate arranged to cooperate with the same pressure bar so that it receives one end of the paper roll from a paper return roller to said support plate. In any case, both the support roller and the support plate should always allow the sheet of paper to run under said pressure bar while the user pulls the paper to remove said sheet.
    According to the same preferred embodiment, the pressure bar is arranged and adapted to press the paper as a result of the force of gravity acting on the mass of the bar and, advantageously, the mass of said bar is determined as a function of the resistance which offers the paper and / or the type of perforated paper, to be able to pull the paper and cut it


    easily by the pre-cut line without tearing it. It has been observed that, for example, a suitable mass of the pressure bar can be a mass equal to or greater than 200 gr.
    Advantageously, said dispenser comprises means for regulating the pressure exerted by the5 bar on the paper depending on the resistance offered by the paper and / or the type of perforationWho owns the paper.
    According to one embodiment, said means for regulating the pressure comprise a set of springs arranged in an upper cover of the dispenser housing so that when closing
    10 the cover the springs act on the pressure bar.
    Preferably, according to one embodiment, the pressure bar is joined articulated to the housing so that it is capable of being raised to a higher position so that the paper roll can be easily removed. For example, each end of said pressure bar
    15 is attached to a swivel arm that is articulated by one of its ends to a side wall of the housing. According to another embodiment, the pressure bar can be attached to a flip top cover of the dispenser housing so that said bar is capable of contacting the paper when closing said top cover.
    20 Again preferably, the paper cutting element is disposed on a support surface, such as a paper support platform, which is pivotally mounted in the dispenser housing and, advantageously, the dispenser comprises means for fixing the angular position of said support surface. In this way, the paper exit angle can be modified depending on the type of paper.
    25 According to a preferred embodiment, the cutting element is arranged in a edge of the paper support surface.
    One of the advantages of the invention is the possibility of using types of cutting elements
    30 more effective and reliable. For example, the cutting element may be a profile with protuberances or a profile with a live edge. Normally, the cutting element will be in the edge of the support surface where the change of direction of the paper occurs.
    The housing will be sized so that it can be hung from a wall, or deposited on a support table, and preferably will comprise a cover arranged on one side for


    facilitate the removal of the paper roll. The means for holding the paper roll can be, for example, a reel holder.
    The paper dispenser of the present invention may be adapted to dispense sheets of5 pre-cut paper of any type of paper. For example, sheets of cellulose paper from a
    or several layers, suitable for hygienic use, for packaging or for use in catering or similar. DESCRIPTION OF THE DRAWINGS

    EMBODIMENTS OF THE INVENTION
    Next, several embodiments of the invention are briefly described, as an illustrative and non-limiting example thereof, referring to the figures.
    5The present invention includes an apparatus for dispensing pre-cut paper sheets in formof roll with a certain length so that it should not be exerted on the paper forcesome to use in your court.
    The pre-cut paper sheet dispenser shown in the embodiments of the figures comprises a housing 1 with a bobbin holder 2 for holding a roll 3 of paper or other similar pre-cut element. It also comprises cutting means 4, 5 of the paper, to form sheets 3a of pre-cut paper, and means for holding 6, 7 one end of the paper of said roll once a sheet 3a of pre-cut paper 3 has been removed. The fastening means of
    15 paper comprises a pressure bar 6 arranged and adapted to permanently contact the paper while the user pulls the paper to remove a sheet 3a. Likewise, the cutting means comprise a cutting element 4 provided on a support surface 5 of the paper which is associated with the pressure bar 6. In this way, the sheet 3a of paper or the like is susceptible to being cut manually by said cutting element 4 when the
    The user modifies the direction of the paper in contact with a edge of said support surface 5 while the paper remains tensioned by the pressure bar 6.
    When the paper 3 is retained by the clamping means 6, 7, when the user pulls the free end of the paper 3, a tension is ensured that helps the paper break in the element 4 of
    25 cut but not excessive to avoid unwanted breaks in the clamping line. The clamping means 6.7 also have the function of preventing the paper from backing after its breakage. In this way there is always a section of paper 3 available for a new service.
    The change of direction and pre-cutting (not shown) of paper 3 enable manual cutting 30 without requiring additional elements to make the cut.
    In all embodiments, the pressure bar 6 is arranged and adapted to press a sheet 3a of paper onto an auxiliary support base 7. Likewise, the paper 3 must be able to run between said auxiliary support base 7 and said pressure bar 6 while the user pulls the paper 3 to remove a sheet 3a. The auxiliary base 7 may have


    several forms: a plate, a roller, a profile,… provided that the paper 3 is clamped between the bar 6 and the auxiliary base 7.
    To facilitate the correct orientation of the paper 3 as it unwinds, when the auxiliary base 75 is a support plate, the dispenser 1 also includes a roll 8 of paper re-sending 3to said support plate (see figure 3).
    According to the embodiment shown in Figures 1 and 2, the bar 6 has means for regulating its pressure on the paper 3 depending on the strength and type of perforation the paper possesses.
    10 3. If the paper 3 is very strong, it will be necessary to increase the pressure to cause the breakage. On the other hand, if it is weak, excessive pressure can cause unwanted breaks in the clamping line.
    Normally, a bar 6 that rests on the base 7 simply by gravity is
    15 enough. The mass of the pressure bar 6 can vary depending on the strength and type of paper, but a mass of 200 gr can suffice.
    In the embodiment described in Figures 4 to 8, the bar 6 is connected articulated to the housing 1 so that it is capable of being raised to a higher position for
    20 being able to easily remove the roll of paper 3. For example, each of the ends of said pressure bar 6 is connected to a rotating arm 13 which is articulated by one of its ends to a side wall of the housing 1.
    An example of means for regulating pressure can be a spring system 9 arranged
    25 in a flip top cover 10 of the dispenser housing 1 so that when closing the lid 10 the springs 9 act on the pressure bar 6. When the lid 10 is opened, the springs 9 or its support can be operated to increase or decrease the pressure.
    In the embodiments shown in Figures 1 and 2, and 4 to 8, the support surface 5 is
    30 swiveling mounted on the housing 1 in order to be able to modify the angle "α" of paper cutting. In this way the change of direction that occurs on the cutting element 4 is controllable. In any case, whether the tilting support surface 5 or not, this surface will be arranged so that the value of the angle "α" of paper cutting is between 120 and 150 ° (see figure 3 and figure 5)


    The cutting element 4 will generally be arranged in the edge of said paper support surface 5, which may be a live edge or a series of protuberances, for example teeth distributed in the edge.
    5 The housing 1 can be arranged in several positions, usually hanging on a wall, or placed on a support table. For that the dimensions should be calculated according to their use. In a preferred embodiment, the paper exit will be at the top of the housing 1.
    10 Finally, the paper roll 3 can be removed by the top cover 10 where the means for regulating the pressure are arranged or on a side cover 11.
    Other variants of the dispenser may include a fabric 12 or elastic element that frictionally restrains roll rotation, wall brackets, rubber studs for support on a table or on the table.
    15 floor
    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the dispenser is susceptible to numerous variations and modifications, and that all of the mentioned details may be replaced by others.
    20 technically equivalent, without departing from the scope of protection defined by the appended claims.
