    Field of the Invention
    The invention relates to a shock device for a treatment machine
    10 of a textile band displaced by an impulse gas, said device comprising a static shock panel with an anterior surface intended to receive the shock of said textile band when, during the treatment, said textile band is transported by said impulse gas and a rear surface, said panel further comprising a plurality of passage openings of said supply gas.
    Also, the invention relates to a machine for the treatment of a wide textile band comprising first and second accumulation chambers of said band with first and second collection areas of said band, a transport conduit of said band that extends between a first and a second
    20 ends, said first and second chambers communicating with each other and that it is adapted to transport said band in its interior to the width, gas drive means functionally connected with said duct to insufflate gas in its interior in an alternative way and transport said said band between said first and second cameras, and a shock device comprising a
    25 static shock panel with a front surface intended to receive the shock of said textile band when, during treatment, said textile band is transported by said discharge gas and a rear surface, said panel further comprising a plurality of passage openings of said drive gas.
    State of the art
    Machines for the treatment of textile bands are known in the state of the art, in which a textile band is displaced along a duct between two band accumulation chambers, transported by a discharge gas that is usually air . Along the duct between both enclosures of band accumulation or at the ends thereof, one or more active or passive shock devices are provided, against which the band being treated impacts. With active tapping, it is the devices that hit the band as it passes. On the other hand, in the second case of passive tapping, it is the band that hits passive or static shock devices, with a force directly related to the speed of movement of the band. Thus, in passive tapping the shock devices are still, so that the higher the travel speed, the more intense the blow. These treatments are
    15 known as tumbleado, which is an adaptation of the English term 'tumblingquot; The assembly ensures that the textile band has a softer, more flexible and bulky texture due to the relaxation of the band structure.
    Figures 1 and 2 show an example of a machine with a shock device 200
    20 passive, state of the art. As can be seen, in these enlarged partial views, the textile band 204 is displaced along a transport conduit 208 that communicates two accumulation chambers of band 204, provided at each end of the conduit 208. At end of the transport conduit 208, in the corresponding accumulation chamber 210 a device of
    25 crash 200. This crash device 200 has a curved crash panel 202, formed by longitudinal bars of square or circular section, separated at regular distances and joined together by their ends. In this machine, the textile band 204 is driven to collide with the shock panel 202 with a force proportional to the speed of the air flow. After the crash, thanks to the
    30 curvature of the shock panel 202, the textile band 204 falls by gravity in an orderly manner in a pick-up area 206 of the basket-shaped band.
    This type of machine with passive shock devices is widely used to treat, preferably, but not exclusively, textile towel bands. Until today, the machine worked satisfactorily for the previous requirements of the consumer. However, in recent times, 5 new needs or fashions related to the finishing of the textile band have appeared. For some time now, the consumer wants the textile band to have an even softer texture than was usual. In other cases, the consumer wants a textile band with an aged appearance. To achieve this goal, it is necessary to increase the force with which the band collides on the shock device.
    10 The greater the impact of the band, the greater the level of fiber breakage, which affects the feel and appearance of the band in the desired way, that is, greater smoothness and more aging.
    To achieve this increase in impact force, this type of machine must be
    15 increase the speed of the air flow with which the textile band is transported between the band accumulation chambers. This increase in the speed of the supply air is associated with a drawback that did not occur in the previous treatment procedure. Because the air passes through the openings 212 of the shock panel 202 at high speed, in the accumulation chambers 202 of band 204,
    20 produces a turbulent movement of air beyond the shock panel 202. This air flow causes the undulating movement of the protruding textile strip 204 of the upstream pick-up zone 206, as seen by the band section with reference A in Figure 1. This undulating movement causes the band 204 that accumulates in the basket of the collection area 206
    25 is messy. This effect can cause tangles in the band 204 and unwanted shutdowns of the machine.
    Summary of the invention
    The purpose of the invention is to provide a shock device for a machine for treating a textile band by means of a delivery gas of the type indicated at the beginning, which avoids unwanted entanglements of the band and facilitates an orderly accumulation thereof in the area. of collection of the treatment machine.
    This purpose is achieved by a shock device for a machine
    5 treatment of a textile band by means of an impulse gas of the type indicated at the beginning, characterized in that it also comprises a deflector panel away from said shock panel on the side of said rear surface and said deflector panel being mounted to deflect the direction of said outgoing drive gas of said shock panel in the direction of collection of said textile web.
    First, it should be noted that in the context of the invention, a shock panel refers to a solid structure provided with gas passage openings on which the textile strip to be treated can collide in order to soften its fibers. Therefore, different configurations of the shock panel are conceivable. So,
    The shock panel can be flat with a plurality of through openings, but it can also be a corrugated plate, multiple bars joined together, a stepped surface or the like.
    In relation to the supply gas according to the invention, preferably the gas is dry air. However, water vapor or other similar gases can also be used.
    That said, thanks to the deflector panel of the shock device according to the invention it is achieved that the gas that passes through the openings of the shock panel is diverted and oriented towards the zone of collection of the band instead of projected towards the chamber producing turbulence. This has two simultaneous positive effects. First, the gas is oriented in the desired direction, which causes the textile band to accumulate in an orderly manner. To this effect, the second effect must be added, consisting of the fact that the exit zone of the textile band is also protected through the deflector panel against the turbulence that the outgoing gas
    30 may cause the rest of the band accumulation chamber.
    On the other hand, the device according to the invention has the additional advantage that it can be easily installed in the state-of-the-art machines, which is a notable advantage since it allows updating existing machines in a simple way.
    Furthermore, the invention encompasses a series of preferred features that are the subject of the dependent claims and whose utility will be highlighted later in the detailed description of an embodiment of the invention.
    10 The separation between the shock panel and the deflector panel can vary considerably the way in which the textile band is deposited in the collection area of the machine. Depending on what situations it may be desirable for a slight turbulence to be present in the area of shock of the band on the anterior surface of the shock panel. However, this slight turbulence can reduce the
    The intensity of the shock on the shock panel and cause some slight undulations that, although not harmful since they do not cause tangles in the machine, can cause some wrinkles on the surface of the band. Therefore, in a preferred embodiment that aims to eliminate wrinkles on the surface of the band in the collection area, said deflector panel is removed from
    20 said shock means a distance such that, in operation, a gas mattress is formed between said anterior surface of said shock panel and said textile web.
    It may also be necessary to improve machine adaptability to different
    25 tissues Depending on the weight of the textile band, different speeds of supply gas will be necessary. Therefore, in another advantageous embodiment that seeks the adaptability of the machine to the different fabrics, the deflector panel is connected to said shock panel through a support and said support allows to modify the relative distance between said deflector panel and said shock panel So how much
    The higher the velocity of the supply gas, the greater the separation distance between the deflector panel and the shock panel.
    In a preferred embodiment that pursues the ease of modifying the distance between the shock panel and the deflector panel, said support is configured to allow modifying said relative distance by tilting. On the other hand, alternatively or in addition to the possibility of tilting the panel
    5 deflector, said support is configured to allow modifying said relative distance by a linear displacement or approach to said shock panel.
    In another embodiment said deflector panel is separated from said 10 shock panel between 10 and 35 cm.
    In a particularly preferred embodiment that seeks to allow the textile band to accumulate in the most orderly manner possible, said deflector panel is mounted to deflect the direction of said discharge gas downwards. Thanks to the flow
    15 constant entering the chamber, combined with the force of gravity, the textile band falls into the collection area very regularly. This embodiment is more stable against oscillations in the flow rate of the flow.
    The deflector panel can have multiple shapes, as long as it deflects the air
    20 projection of the shock panel. However, in a particularly preferred manner that seeks to reduce turbulence, said deflector panel is a flat and continuous panel.
    Also in the preferred embodiment that seeks maximum utilization
    25 of the air flow, said deflector panel extends at least beyond the limits of said shock panel.
    The invention also aims to provide a machine for the treatment of a textile band of the type indicated at the beginning, which prevents tangles
    30 desired band and facilitate an orderly accumulation of the textile band.
    This purpose is achieved by a machine of the type indicated at the beginning which further comprises a shock device according to the invention.
    Obviously, a machine of this type has the advantages that have been set out in the previous paragraphs referring to the shock device.
    Likewise, the invention also encompasses other detail features illustrated in the detailed description of an embodiment of the invention and in the accompanying figures.

    Detailed description of embodiments of the invention
    A first embodiment of a machine 1 according to the invention for the treatment of a textile band 100 can be seen in Figures 3 to 5.
    In general, machine 1 is divided into first and second chambers 4, 6
    10 of accumulation of the band 100. The band 100 enters the second chamber 6 through the upper part of the machine 1 by means of a feed roller 32 and is removed from the first chamber 4 by the upper part of the opposite end by means of a roller extraction 34.
    15 The feed roller 32 introduces a sufficient amount of band 100 into the second chamber 6 so that it accumulates in the second lower collection area 10 of the machine 1. Similarly, the extraction roller 34 also allows a certain amount of accumulation to be accumulated. amount of band 100 in the first collection zone 8. It is precisely these accumulations of band 100 that allow treatment
    20 of the alternative band 100 which will be explained below.
    As can be seen in Figure 3, the first and second chambers 4, 6 are communicated by a transport conduit 12 of the band 100 extending between a first and a second end 14, 16. The transport conduit 12 is
    25 adapted to transport the band 100 in its interior to the width.
    The treatment of the assembly in this machine 1 consists in that the band 100 strikes multiple times on the shock devices 2 mounted at the exit of the first and second ends 14, 16 of the duct 12. To this end, the machine 1 also has 30 means of gas drive 18 that are formed by an appropriate motor and fan that have sufficient power to move the band 100 through the conduit 12 only by the force of the injected gas.
    Preferably, the gas is dry air, but humid air, steam, or others can also be used. For example, the fan can be a centrifugal fan, without ruling out other equivalent solutions that can incorporate devices, such as a compressor or other similar devices.
    The drive means 18 are functionally connected to the conduit 12 through the conduits 36a, 36b. Thanks to valves not shown in detail in the figure, the desired conduit 36a, 36b can be selected so that the gas stream exits the corresponding outlets 38 leading the band 100 towards a
    10 another camera. Thanks to the inclination of these outlets 38 with respect to the conduit 12, the insufflated gas inside the conduit 12 is oriented towards the corresponding chamber and by alternating the opening of the valves, the band 100 can alternately be transported between the first and second chambers 4, 6.
    15 As already mentioned, at the exit of the first and second ends 14, 16 of the conduit 12 there are provided the shock devices 2 object of the invention on which the band 100 can collide to apply the corresponding tightening.
    The shock devices 2 of the machine 1 according to the invention comprise a
    20 shock panel 20 passive or static similar to that used in prior art machines. Each shock panel 20 has a front surface 22 intended to receive the shock of the textile band 100 when, during the treatment, the band 100 is transported by the supply gas. On the other hand, the shock panel 20 has a rear surface 24.
    Also, in Figure 5 it can be seen that the shock panels 2 according to the invention have a plurality of passage openings 26 of the supply gas. The absence of these openings 26 would cause the formation of an air cushion of such a high intensity that it could happen that the band 100 did not collide
    30 against the crash panel 2.
    On the other hand, as seen in the state-of-the-art machine, the outgoing gas at high speed passed through the shock panel 20 through its openings 26 and caused, among other effects, the undulation of the outgoing band 100 of the first
    or second collection zones 8, 10 of the band 100. These collection zones have
    5 basket shape in this embodiment. This in turn caused the disorder of the band 100, which was highly undesirable. Thus, to solve this problem, the device 2 according to the invention further comprises a deflector panel 28 away from the shock panel 20 provided on the side of the rear surface 24 of the shock panel 20. In Figure 4 it can be seen through the arrows with the reference B that the
    10 deflector panel 28 is mounted to divert the supply gas in the direction of collection of the textile band 100. In this particular embodiment, the deflector panels 28 are oriented at an angle that deflects the direction of the discharge gas downwards, that is, in the downward direction of the respective first and second collection areas 8, 10. As can be appreciate in the figures, the
    15 deflector panels 28 are solid and continuous, so that they completely prevent the passage of gas through it. However, in an alternative embodiment, the deflector panels 28 may have openings or interruptions, provided that they are at least partially offset with respect to the openings 26 of the shock panels 20. This prevents the outgoing gas jet have the
    20 sufficient intensity to cause unwanted ripples of the prior art.
    While not strictly essential for the invention, in order to maximize the impact of the band on the crash panels 20, the panels
    25 deflectors 28 are separated from their corresponding shock panels 20 a distance A such that, in operation, a gas mattress is formed between the front surface 22 of the shock panel 20 and the textile band 100. It has been found as particularly advantageous that the distance A is between 10 and 35 cm (see, for example, Figure 4).
    In this embodiment, each shock panel 20 and each deflector panel 28 are parallel. However, this is not essential for the invention. Therefore, according to the invention, distance A is considered at least the smallest separation distance between the two panels.
    The figures show that the deflector panels 28, in cross section to the
    5 along a plane perpendicular to Figure 4, are flat and continuous panels. However, they alternately have other shapes, such as concave, convex, wavy or others.
    Also to ensure that the outgoing band 100 is not affected by the jet of
    10 air that passes the corresponding shock panel 20, the deflector panel 28 extends at least to the lateral limits of the shock panel 20 in the area of the band's shock, that is to say that it allows to cover the entire width of the band 100 outgoing.
    On the other hand, in this embodiment the deflector panel 28 is connected to the shock panel 20 through a rigid support 30, so that the distance A remains constant and can only be varied if the support 30 is replaced .
    It is also worth mentioning that although in the machine of figures 3 to 5,
    20 show two shock devices 2, the invention also contemplates that there may be only one shock device 2 at one end of the conduit 12, while the other end has other known band treatment devices.
    25 Other embodiments of the machine according to the invention that share much of the characteristics described in the preceding paragraphs are shown below. Therefore, from now on only the differentiating elements will be described, while for the common elements reference is made to the description of the first embodiment.
    30 As seen in the previous embodiment, the support 30 was rigid. Thus, in order to be able to adapt the machine better to the type of textile band 100 to be treated, it is provided that the supports of the shock devices 2 allow the relative distance between the deflector panels 28 and the shock panels 20 to be modified.
    5 For this, in the embodiment of Figure 6, it is provided that the support 30 is movable and is configured to allow modifying said distance A by a linear displacement or approach to the shock panel 20. To do this, in this embodiment, for example, two sliding strips are provided with respect to each other, with a plurality of holes that allow fixing
    10 different distances A by screws. Figure 6 does not show the strips in detail. Thus, the deflector panel 28 can be moved in the direction of the double arrow C.
    In the case of the embodiment of Figure 7, the device 2 is configured to allow modifying said relative distance A by tilting, thanks to the fact that the
    15 support 30 has articulation points 42 and a system of sliding strips that allow tilting of the deflector panel 28 in the direction of the double arrow O of this figure.
    Finally, the embodiment of figure 8 differs from that of figures 3
    20 to 5 in which the impact panel 20 is a flat plate provided with a plurality of circumferential openings 26.
    The embodiments described herein represent non-limiting examples, so that the person skilled in the art will understand that beyond the examples
    25 shown, within the scope of the invention multiple combinations between the claimed features are possible.
