    Short description: Device and method for applying fibers to a substrate with turf on it
    Description
    The invention relates in the first instance to a device for arranging in a substrate with grass sods thereon comprising an earth layer and above it a grass layer of fibers comprising a frame movable over the surface in a direction of movement, a number up and down relative to the frame fiber insertion pins displaceable between a high position and a low position in and from the turf and the substrate, first displacement means for displacing the fiber insertion pins between the high position and the low position, feed means for supplying fiber under the fiber insertion pins while the fiber insertion pins are in are in the high position, during operation during the subsequent displacement of the fiber insertion pins of the fiber insertion pins from the high position to the low position in the turf and into the substrate of the fiber.
    Such devices are known and do not deviate from devices used for directly applying fibers to a substrate, without sods of grass. By combining natural grass with fibers that are inserted into the natural turf, the natural turf is strengthened. This is referred to as hybrid grass or fiber-reinforced grass. Turf is typically used for sports fields if little time is available to place a turf, such as may be the case with sports fields in stadiums used for important sports competitions. To reinforce the turf, it is possible to opt for injecting the fibers into the turf and the substrate, due to time pressure relatively shortly after turf has been applied to the substrate. There is still little talk of fouling through the roots of the grass from the turf to the subsoil. This entails the risk that during the injection of the fibers, wherein the fibers are inserted through pins into the turf and the substrate, more specifically during the retracting movement of the pins, the turf is moved upwards and comes away from the surface. This is at the expense of the quality of the hybrid turf, for example because it allows parts of the fibers to be folded flat between the substrate and the turf. To solve this problem, the turf is made heavier by spraying it and / or by sprinkling extra soil on the turf. In the first case, the turf becomes spongy, which can be at the expense of the flatness of the hybrid turf. In the second case, people "bury" the grass, which is also undesirable. It is an object of the invention to provide an improved solution to the above problems. To this end, the device comprises at least one retaining member for locking the turf on the subsurface in the vertical direction, at least while the first displacing means moves the fiber introduction pins from the low position out of the subsurface and from the turf into the direction of the high position. The retaining member thus impedes in an extremely reliable manner the movement of the turf along with the fiber insertion pins without the turf having to be weighted for this purpose with water or earth.
    According to a very advantageous embodiment, the device comprises second displacement means for moving the retaining member up and down between a low operative position and a non-operative high position, wherein in the operative position the at least one retaining member confines the turf in the vertical direction. Thus, the possibility is offered that during the displacement of the device along the substrate, such as is necessary to insert fibers into the ground in a complete field or at least over a larger surface, the confinement member is guaranteed free from contact with the turfs so that they cannot be damaged by the retaining member either.
    In order to achieve the latter advantage, it is further preferred that the second displacement means are adapted to move the retaining member up and down between the active position and the non-active position for each up and down movement of the fiber insertion pins and / or the second displacement means are adapted to hold the retaining member in the non-operative position during displacement of the device over the substrate.
    In order to be able to guarantee that the retaining member is effective from the start of the retracting upward stroke of the fiber insertion pins, it is advantageous if the second displacement means are adapted to keep the retaining member in the operative position during at least the last part of the displacement by the first moving means of the fiber introduction pins from the high position to the low position.
    According to a possible embodiment, the device comprises sensor means for measuring the distance viewed in vertical direction between the earth layer and the frame, the device further comprising control means which are adapted to determine the low effective position of the retaining member. It can thus be achieved that the retaining member in the operative position is relatively short, for example 1 mm, above the earth layer so that the retaining member does not press on the turf, which could damage the turf.
    In particular, but not exclusively if no use is made of the above-mentioned sensor means, it may be advantageous if the second displacement means are adapted to press the earth layer into the active position by the retaining member. By pressing the earth layer with certainty, the locking effect is guaranteed by the locking element.
    The at least one retaining member has passages through which the first displacement means move the fiber insertion pins during operation during the up and down movement of the fiber insertion pins between the high position and the low position. The respective passages can also serve as guides for the fiber insertion pins.
    If the passages are provided in an elevated part of the enclosing member, there is no need to close off the immediate vicinity of the location where the fiber insertion pins are inserted into the ground layer with the enclosing member. .
    It can further be advantageous if the at least one retaining member has further passages before and after the positions in which the fibers are inserted into the turf and the substrate during operation. The mass of the retaining member can thus be limited and the further passages moreover offer space for grass of the turf and possibly fibers already inserted into the turf and substrate to extend therethrough.
    The invention can in particular be applied effectively if the at least one retaining member is adapted to operate within a distance of at most 50 cm, preferably of at most 35 cm, viewed in the direction of movement and / or if the at least one retaining member is symmetrical with respect to the fiber insertion pins.
    The present invention furthermore relates to a method for applying fibers to a substrate with grass sods thereon, comprising an earth layer and above it a grass layer. The method according to the invention comprises the repeating steps of A moving a number of fiber insertion pins with first displacing means to a high position in which a lower end of each fiber insertion pin is spaced above the turf, B supplying fibers with feed means below the respective lower ends of each fiber insertion pin, C moving the fiber insertion pins downwards from the high position to a low position with the first displacement means, during which displacement the fibers are inserted by the fiber insertion pins into the turf and into the substrate, D displacing the fiber displacement pins upwards with the first displacement means the fiber insertion pins from the low position in the direction of the high position until the lower end is above the turf or at least above the earth layer thereof. E moving the fiber insertion pins horizontally over a stroke length along the substrate, wherein at least during execution of step D the turf is stored on the substrate by a retaining member in the vertical direction.
    More preferably, during each step D, second displacement means hold the retaining member in a low operative position and move between execution of two successive steps D the second displacement means prior to step E move the retaining member from the low operative position to a non-operative high position and move after step E the retaining member from the non-active high position to the low active position.
    The invention will be explained in more detail below on the basis of the description of two possible, non-limiting, interpretable embodiments of an apparatus according to the invention and of a possible, also non-limiting, interpretation of the invention, implementation of the method according to the invention with reference to the following figures:
    Figures 1a to 1e show diagrammatically in vertical cross-section five successive steps during the application of fibers to turf on top of it according to the invention,
    Figure 2 shows Figure 1d in more detail in detail,
    Figure 3 shows figures 1d and 2 in sketchy perspective view
    Figure 4 shows a device such as that which can alternatively be applied according to the invention.
    Figures 1a to 1e schematically show a substrate 1 for a hybrid grass field to be laid on which turfs are laid, each of the turfs has an earth layer 2a and above that a turf layer 2b (see also Figures 2, 3 and 4). With the grass layer 2b is meant the layer above the earth layer 2a within which extends the grass whose roots extend in the earth layer 2a.
    For the injection of fibers into the turf 2 and into the substrate 1, a vehicle designed with a device adapted for the said injection of the fibers is used. In use, the vehicle moves in a direction of movement that runs from bottom left to top right in Figure 3. In the figures, only the parts of the device that are important for the present invention are shown. A detailed description of all components of the injection device is superfluous here because such devices are already known to those skilled in the art, for example from Dutch publication NL 1014978.
    Figure 1a shows how a fiber 3 is made to length and extends horizontally straight under a pin 4. That pin, which forms part of a row of pins (see also Figure 3), is displaced relative to the The frame of the vehicle can be moved vertically up and down between a high position according to figure 1a and a low position according to figures 1c up to and including 1e. During the downward movement, the pin first moves against the fiber 3, in the middle of its length, and then through a guide 5 with a limited passage so that the fiber 3 is, as it were, folded double around the tip of the pin 4. For an improved guide, conductor 4 itself can also be moved between a high position (figures 1a and 1e) and a low position (figures 1b to 1d).
    During the downward movement, the pin 4 first protrudes into the turf 2 (Figure 1b) and then into the substrate (Figure 1c), for example 20 cm deep. Subsequently, the pin 4 moves back upwards to the high position (Figures 1d and 1e) because of the effectiveness of the displacement means. During this retracting movement, the fiber 3 remains behind in the substrate. The fiber is made to such a length and the stroke length of the pins 4 is so great that the two free ends of the fibers 3 after the pins 4 are pulled back above the earth layer 2a but still lower than the tops of the grass. extend the grass layer 2b.
    Due to the retraction of the pins 4, there is a risk that a turf 2 is briefly pulled up. This can be at the expense of the flatness of the final hybrid turf. Moreover, folds are formed in one or both fiber halves of fibers 3, which are clamped between the substrate 1 and the turf 2 as soon as the latter falls back again. To prevent such problems, the injection device comprises a retaining member 7. This is displaceable by means of displacement means (not shown) relative to the frame of the vehicle between a high, non-active position (figures 1a and 1e) and a low, active , position (figures 1b to 1d). The retaining member 7 is profile-shaped and, for example, made of steel or plastic. The retaining member 7 is symmetrical with respect to the pins 4 and comprises two abutment surfaces 8a, 8b which are connected to each other by a centrally raised bridge part 9. On the outer sides of the abutment surfaces 8a, 8b, the retaining member further comprises inclined surfaces 10a, 10b and raised edges 11a, 11b.
    The distance between the longitudinal edges of the two abutment surfaces 8a, 8b directed away from each other, or between the edges where the abutment surfaces 8a, 8b and the inclined surfaces 10a, 10b connect to each other, is approximately 22 cm. This distance determines the width, extending in the direction of movement, of the area within which the confinement member 7 operates, as will become apparent below. The length of the area in question is determined by the length of the row of pins 4. In the central raised bridge part 9 a passage 12 is provided for each pin 4, the diameter of which is so small that the passages 12 for the associated pin 4 have a conductive function can fulfill, for example in the case that a pin encounters a hard object in the subsurface 1. Furthermore, considerably larger passages 13 are provided in the abutment surfaces 8a, 8b.
    The retaining member 7 functions as follows: During the downward movement of the pins 4, the retaining member 7 also moves from the high inactive position to the low active position (Figure 1b). Ideally, the low operative position is such that the retaining member, more specifically the abutment surfaces 8a, 8b thereof, are a short distance, for example 1 mm, above the earth layer 2a. Because the thickness of the earth layer 2a can vary, it is possible within the scope of the invention to use a sensor, for example a mechanical touch sensor or an optical sensor, which determines the vertical distance between the frame and the earth layer. Control means can then be adapted to control the displacement means for the confining member such that the low effective position is determined on the basis of the measurement by the sensor. Alternatively, it is also conceivable that, for the sake of certainty, one chooses to choose the low effective position of the retaining member such that it is located just below, for example 1 or 2 mm, the theoretical ideal effective position. Thus, in practice, the retaining member in the operative position will exert a certain pressure on the earth layer. In both cases the grass in the grass layer 2b as well as the fibers that already protrude from the earth layer 2a into the grass layer 2b are pressed flat to a certain extent, except at the positions of the passages 13. This is clearly visible in figures 2 and 3. This gives one advantage of the passages 13. Another advantage of passages 13 is that they provide the retaining member 7 with a lower weight, which is in any case favorable from the point of view of mass inertia effects.
    According to a variant of confinement member 7, it does not have a raised bridge part 9, but the abutment surfaces 8a, 8b connect directly to each other and there is thus a single abutment surface with the passages 12 and (optionally) the passages 13 therein.
    Figure 4 shows another device to be used according to the invention. Components in Figure 4 corresponding to components in Figures 1 to 3 are shown with corresponding reference numerals. The device differs in particular with regard to the embodiment of the retaining member. Instead of profile-shaped retaining member 7, use is made of two retaining rollers 15a, 15b which are combined with a central bridge-shaped retaining body 14 through passages 16 of which pins 4 move up and down. In use, the retaining rollers 15a and 15b roll over the earth layer 2a as the device is moved over the substrate 1 and thus confine the turf 2 in the vertical direction.
