Brief description: Method and device for applying fibers to soil and a combination of a support member and a collection of fibers.
Description
The present invention relates to a method for grounding fibers with a device comprising the steps of A providing a fiber,
B positioning the fiber with the aid of positioning means of the device under a fiber insertion pin of the device,
C moving the fiber insertion pin down and up, the fiber being pressed into the ground during the falling part of the movement,

It is known to provide plastic fibers in soil for the purpose of laying out so-called hybrid grass fields, in particular sports fields, wherein the fibers are used in combination with natural grass. For the application of fibers, use is made of relatively large moving machines which move step-by-step and according to parallel strips over the area where the hybrid field is to be applied. The machines have a row of, for example, at least 60 pins, which row, for example, has a length of at least
Has 1.2 meters. This length determines the width of the aforementioned strips. The machine carries rotatable spools around which fibers are wound in long lengths of for example 5000 meters. The number of spools usually corresponds to the number of pins. In use, those fibers are unwound from the spools and brought to a position below the pins. The pins move down and up. During the downward movement, a short length of fiber which is separated at that moment, for example by a cutting operation, from the fiber on the roll is pressed into the ground by the associated pin. The Dutch publications NL 20141189 and NL 1014978 give examples of devices with which fibers as described above can be applied to the soil. The surface of hybrid fields is typically a few thousand square meters, for example around 7500 square meters. With such sizes, the known mobile machines can still be used economically in a responsible manner. However, as the surface area becomes smaller, the use of the known machines becomes less profitable and even economically irresponsible.
The invention is based on the recognition that there is a latent need for applying fibers in soil in an economically responsible manner over relatively small surfaces of, for example, less than 100 square meters or even less than 10 square meters. Examples include repair work in heavily loaded areas of a hybrid grass field such as a penalty area of a football field, the area that extends directly to the perimeter of an already existing hybrid grass field, lawns in private or non-private gardens, public areas paddy fields in residential areas, on walking paths or on dikes. Particularly for repair work, it is known per se to manually puncture fibers into the ground. This is extremely time-consuming and therefore expensive. The use of the known devices as mentioned above is also not possible in an economically responsible manner for this type of relatively small-scale applications. The object of the invention is to meet that need for which the invention provides a method according to the preamble in which the fiber according to step A forms part of a collection of fibers of which one fiber is positioned under the fiber insertion pin during step B during step B. For a good understanding of the invention, it is noted that the term "fiber" in the present text is to be understood to mean an individual fiber with a length of at most 50 cm. A fiber must therefore be distinguished from a fiber wire as it is wound around a spool in lengths of many hundreds of meters. The fibers are typically inserted into the soil for a maximum of 20 cm during step C. With the above-mentioned length of a maximum of 50 cm, account is taken of a limited length of the fiber that protrudes above the ground after it has been pressed into the ground and the possibility of engaging a fiber in the middle through the fiber insertion pin, so that the fiber is folded double. The minimum length of an individual fiber is 10 cm. The invention makes use of a collection of fibers which have already been made to a desired length prior to the work to introduce soil fibers into the soil in a surface. By no longer using a number of coils around which fiber threads are wound and by not making the fibers at a desired length on location but already offering the fibers directly at the desired length on location, it is possible to use the tool with which the fibers can be installed in the soil easier to implement than the existing machines. After all, thanks to the invention it is possible to dispense with provisions for accommodating spools, for unwinding the fiber threads from the spools and for making the fibers to length as required by machines according to the prior art. This also has a positive influence on the safety with which the device with which the method according to the invention can be carried out.
It may be advantageous if the longitudinal direction of the fiber insertion pin encloses an angle during step C with a direction parallel to the direction of movement according to step D. Thus, for example, starting from a fixed length of the fiber, the depth of the layer of the soil in which the fiber is are limited, which may be interesting, for example, if heating pipes are provided in the ground at a certain depth. In addition, the force required to pull a fiber out of the ground with a pulling force oriented perpendicular to the ground can be increased. Moreover, natural grass roots can thus more easily become entangled with a number of fibers, thereby improving the anchoring of the natural grass roots.
The size of the angle can be between 0 degrees and 60 degrees, more preferably between 15 degrees and 50 degrees.
The invention can be applied with advantage if the ground concerns a slope with an angle of inclination, wherein the direction of movement according to step D extends parallel to the slope. Such a slope can, for example, form part of a slope or a dyke.
In case a slope is used, the longitudinal direction of the fiber insertion pin can advantageously extend in the vertical direction during step C.
The measures related to previous embodiments in which the longitudinal direction of the fiber insertion pin during step C includes an angle with a direction parallel to the direction of movement according to step D can also be advantageously applied in a method according to the prior art. Therefore, the present invention also relates to a method of grounding fibers with a device comprising the steps of A providing a fiber,
B positioning the fiber with the aid of positioning means of the device under a fiber insertion pin of the device,
C moving the fiber insertion pin down and up, the fiber being pressed into the ground during the falling part of the movement,
D moving the fiber insertion pin parallel to and above the ground in a direction of movement over a step length,
E repeating steps A to D, wherein the length direction of the fiber insertion pin during step C includes an angle with a direction parallel to the direction of movement according to step D.
According to a further embodiment, the resistance determined by the fiber insertion pin due to the displacement in the ground is determined during step C and that the speed with which the fiber insertion pin moves in the ground during step C depends on the determined resistance. The resistance mentioned depends on the type of soil and other circumstances, such as the moisture content in the soil. Furthermore, in general, the resistance is greater the deeper the fiber insertion pin is inserted into the ground. The mechanical load-bearing capacity of the fiber insertion pin is limited. By making the speed at which the fiber insertion pin displaces into the ground during step C dependent on the determined resistance encountered by the fiber insertion pin, the load capacity of the fiber insertion pin can be utilized to the maximum in order to thus shorten the cycle time of the displacement according to step C.
The aforementioned dependence between the determined resistance and the speed of the fiber insertion pin can also be advantageously applied in a method according to the prior art. The present invention therefore also relates to a method for laying fibers with a device comprising the steps of
A providing a number of fibers,
B positioning the fibers under the fiber insertion pins of a row of fiber insertion pins of the device arranged in a row with the aid of positioning means of the device,
C moving the fiber insertion pins down and up, during which the fibers are pressed into the ground during the descending part of the displacement, D moving the fiber insertion pins parallel to and above the ground in a direction of movement,
E repeating steps A to D, wherein during step C the resistance which the fiber insertion pin experiences due to the displacement in the soil is determined and that the speed at which the fiber insertion pin moves into the soil during step C depends on the determined resistance .
In order to increase the capacity, during step C, preferably simultaneously for shortening the cycle time, a number of fiber inserting pins arranged in a row can be moved down and up to press an equally large number of fibers into the ground.
It is possible here for the fiber insertion pins arranged in a row to move synchronously, so that the device can be of relatively simple design.
To limit the total resistance that the fiber insertion pins may encounter during the pressing of the fiber insertion pins into the ground, whereby, for example, there may be a risk that the device used for carrying out the method is pushed upwards, it may be preferable that during step C moves asynchronously a first part of the number of fiber insertion pins and a two part of the number of fiber insertion pins. Thus, for example, during the last part of the downward displacement of the second part of the number of fiber insertion pins during which part of the downward displacement the resistance experienced by the fiber insertion pins concerned is greatest, the first part of the number of fiber insertion pins can already move upwards with the reaction forces which operate in the opposite direction between the ground and the first part of the number of fiber insertion pins and the second part of the number of fiber insertion pins and thus to some extent cancel each other out.
A good compromise between, on the one hand, the pursuit of a short cycle time and, on the other hand, the pursuit of a limitation of the resistance which the fiber insertion pins encounter during the downward movement due to the ground can be achieved if the time period between the starts of the downward movements of the first part of the number of fiber insertion pins and of the second part of the number of fiber insertion pins is less than 25%, preferably less than 15%, of the time period between the start of the downward movement and the end of the upward movement of the first part of the number of fiber insertion pins .
In case the resistance determined by fiber insertion pins due to the displacement in the ground is determined during step C, it is also possible that the time period between the starts of the downward displacements of the first part of the number of fiber insertion pins and of the second part of the number of fiber insertion pins depends on the determined resistance. For example, it is conceivable that in soft soil into which the fiber insertion pins can be inserted relatively easily, the aforementioned period of time is shorter than with harder soil. This principle is also applicable to a method according to the state of the art. Then there is a method for laying fibers into the ground with a device comprising the steps of
A providing a number of fibers,
B positioning the fibers under the fiber insertion pins of a row of fiber insertion pins of the device arranged in a row with the aid of positioning means of the device,
C moving the fiber insertion pins down and up, during which the fibers are pressed into the ground during the descending part of the displacement, D moving the fiber insertion pins parallel to and above the ground in a direction of movement,
E repeating steps A to D, characterized in that during step C the resistance which the fiber insertion pin experiences due to the displacement in the ground is determined and the time period between the starts of the downward displacements of the first part of the number of fiber insertion pins and of the second part of the number of fiber insertion pins depends on the determined resistance.
According to a possible embodiment, the time period between the start of the downward movement and the end of the upward movement of the first part of the number of fiber insertion pins is equal to the time period between the start of the downward movement and the end of the upward movement of the second part of the number of fiber insertion pins. Such an embodiment of the method is with a relatively simple device, in the sense that it can only have a single drive member for driving both the first part and the second part of the number of fiber insertion pins.
Alternatively, it may also be possible that the time period between the start of the downward movement and the end of the upward movement of the first part of the number of fiber insertion pins is longer than the time period between the start of the downward movement and the end of the upward movement of the second part of the number of fiber insertion pins. Thus, the downward reaction force due to the upward displacement of the first part of the number of fiber insertion pins can be utilized to cause the displacement of the second part of the number of fiber insertion pins to take place faster than the displacement of the first part of the number of fiber insertion pins. In a special embodiment, the upward movements of the first part and the second part of the fiber introduction pins end simultaneously, or at least substantially simultaneously.
To simplify the device with which the method according to the invention can be carried out, it can be advantageous if at least a part of the fiber insertion pins of the first number of fiber insertion pins, preferably all fiber insertion pins of the first number of fiber insertion pins, are located directly next to each other and / or that at least a portion of the fiber insertion pins of the second number of fiber insertion pins, preferably all fiber insertion pins of the second number of fiber insertion pins, are located directly adjacent to each other.
Alternatively, it is also possible that the fiber insertion pins of the first part of the number of fiber insertion pins and the fiber insertion pins of the second part of the number of fiber insertion pins are provided alternately. Thus, the tendency to tilt sideways will be smaller than in the previous embodiment.
If the fiber insertion pins of the first part of the number of fiber insertion pins are driven independently of the fiber insertion pins of the second part of the number of fiber insertion pins, there are more possibilities for shortening the cycle time, or the period of time that step C requires.
Alternatively, it is also possible that the fiber insertion pins of the first part of the number of fiber insertion pins are driven depending on the fiber insertion pins of the second part of the number of fiber insertion pins. The method can thus be carried out with a relatively simple device.
The measures described above in which during step C a first part of the number of fiber insertion pins and a two part of the number of fiber insertion pins move asynchronously can also be advantageously applied in a method according to the prior art. The invention therefore also relates to a method for laying fibers with a device comprising the steps of
A providing a number of fibers,
B positioning the fibers under the fiber insertion pins of a row of fiber insertion pins of the device arranged in a row with the aid of positioning means of the device,
C moving the fiber insertion pins down and up, during which the fibers are pressed into the ground during the descending part of the displacement, D moving the fiber insertion pins parallel to and above the ground in a direction of movement,
E repeating steps A to D, characterized in that during step C a first part of the number of fiber insertion pins and a two part of the number of fiber insertion pins move asynchronously.
The number of fiber insertion pins is preferably at most 35, more preferably at most 25, and / or the length of the row is preferably at most 70 cm, more preferably at most 50 cm. The device with which the method is carried out can thus be carried out relatively lightly and can simply be carried out manually, for example supported by one or a number of relatively light (electric) motors, for example servomotors, with a (joint) power of, for example, situated between approximately 1 kW and 10 kW, making the method particularly suitable for relatively small-scale projects.
A further advantageous embodiment can be obtained if the fibers in the set are mutually positioned by a support member. The support member can contribute to the fibers being correctly positioned under a fiber insert during step B.
To facilitate transport of the fibers for the purpose of step B within the device, it may be preferable for the support member to be band-shaped. The support member can be offered as a role to the device.
Such an embodiment offers the possibility that the carrying member is unwound from a unwinding spool during implementation of the method upstream of the fiber insertion pin, or possibly of a row of fiber insertion pins. The fibers which are located within the length of the unwound part of the band-shaped support member can be pressed into the ground by the fiber insertion pins during step C.
A band-shaped support member also offers the possibility that the support member is wound downstream on a take-up reel during implementation of the method. This facilitates discharge and possible reuse of the support member.
When a support member is used, it can be advantageous if the positioning means engage the support member for positioning the fiber under a fiber insertion pin according to step B. To this end, the support member can for instance be provided with engagement elements such as holes in which teeth of the positioning means engage.
In the case of using a support member and if during step C a number of fiber insertion pins arranged in a row are simultaneously moved down and up to press an equal number of fibers into the ground as discussed above, it may be advantageous if the support member carries the fibers in adjacent rows within which rows the fibers extend parallel to each other and to the direction of movement, the distance between the fibers concerned in a row being equal to the distance between the fiber insertion pins of the device and wherein the positioning means for each step E move the support member over a pitch length in the direction of movement. The pitch length herein corresponds to the distance between adjacent fibers of adjacent rows as they are supported by the carrier and which fibers are pressed into the ground one after the other by the same fiber insertion pin during successive steps C.
Alternatively, it is also possible that because the support member carries the fibers in a single row within which row the fibers extend parallel to each other and to the direction of movement, the distance between the fibers in question being equal to the distance between the fiber insertion pins of the device and wherein for each step E the positioning means move the support member over a pitch length in the horizontal direction transversely of the direction of movement. In the case where the device with which the method is carried out comprises a row of fiber insertion pins, the pitch length in that case corresponds to the distance between the outer fibers of a number of adjacent fibers, which number corresponds to the number of fiber insertion pins of the row of fiber insertion pins plus one.
A practical embodiment is obtained if the fiber is separated from the support member during execution of step C, in particular if the fiber is separated from the support member during execution of step C because of the force that the fiber insertion pin exerts on the fiber during the descending part of the support member. displacement. In the case of a connection between the support member and the fibers, that connection is broken during the said separation.
It may advantageously be possible for the fibers to be connected to the support member. For example, an adhesive connection or that the support member and the fibers are made of the same material and form one integral, for example, band-shaped, component.
The fibers can also be form-connected to the support member. A practical embodiment can thereby be obtained if the fibers are each enclosed over a part of their length between the support member and at least one elongated confinement member which extends transversely to the fibers and is connected to the support member at positions between the fibers or more specifically if each of the fibers is confined between the support member and two elongated confinement members extending parallel to each other.
In the case of an adhesive connection as described above, it may further be advantageous if the at least one elongated confinement member is provided with an adhesive layer on the side facing the support member.
An extremely practical embodiment can be obtained if the support member comprises a passage for each fiber, optionally each of the fibers extending through a passage. The passage can thereby ensure a form-locked connection.
Alternatively, each of the fibers may also cross the associated passageway.
In the case of the use of two confining members per fiber as described above, it may be advantageous if each passage between the two confining members is provided.
If the fiber insertion pin moves through the passage during C, the passage can form a guide for the fiber.
The reliability of the process of pressing the fibers into the ground by the fiber insertion pin can be positively influenced if the support member is clamped by clamping members of the device at least during part of the descending part of step C, which clamping prior to the following embodiment from step B is canceled.
According to a possible embodiment, the support member is designed as a package with compartments for the fibers. In this connection, for example, a supporting member is designed as a blister pack.
A favorable embodiment of the method is characterized in that the fibers have a thickened part. The thickened part can thus serve as a point of engagement for a fiber insertion pin so that a fiber can be pressed into the ground during step C with increased reliability. Moreover, in practice, the thickened part after step C can act as an anchoring of the fiber in the soil.
Filaments of the fiber are advantageously connected to each other at the location of the thickened part. In this way it is possible to prevent or at least considerably reduce the chance that during or after the fibers are being pushed into the ground the filaments of the fibers will move in their longitudinal direction relative to each other.
When the fibers are engaged in the traditional manner at the center of the length by the fiber insertion pin, it is preferable that the thickened part is situated at the center of the length of the fiber.
However, the use of a thickened part also offers the possibility of engaging the fibers from the center. As a result, there is no need for the fibers to be pressed into the ground when folded. Therefore, the thickened part can also be located at the center of the length of the fiber, preferably at one end of the fiber.
According to a possible embodiment, the thickened part is formed by a knot in the fiber. This knot can be laid in a single part of fiber but can also be laid between two parts of fiber so that the two parts of fiber are connected to each other.
According to an alternative, the thickened part is formed by an annular member which extends around the fiber. The use of an annular member offers more freedom with regard to the shape and dimensions of the thickened part.
An extremely practical embodiment, at least from a production point of view, could be obtained if the thickened part is formed by cured glue or if the fiber comprises a thermoplastic material and the thickened part is formed by solidified melt of the thermoplastic material.
The advantages of using a thickened portion in each fiber are particularly relevant if, during the downward movement of the fiber insertion pin, the fiber insertion pin engages the thickened portion or a directly adjacent portion of the fiber.
In the case of the use of fibers with thickened parts and of a passage in the support member for each fiber, as discussed above, it may be advantageous if the thickened part of the fiber adheres to the fiber insertion pin during step B side of the passage and the majority of the length of the fiber is on the side of the passage directed towards the fiber insertion pin, with the fiber insertion pin preferentially moving through the passage during step C.
In particular, but not exclusively, if the carrier is made of non-elastic material, it may furthermore be advantageous if, during step B or C, the thickened part of the fiber through a displacement member of the device from a confining zone of the passage behind at least a part of the peripheral edge of which the thickened part hooks, is moved in the direction of a release zone of the passage, which release zone is in connection with the confinement zone and the circumference of the thickened part fits within the circumference of the passage in the release zone. To this end, the passage can at least substantially have the shape of a keyhole.
The support member can be of both the disposable type and the reusable type. The first case can be beneficial for ease of use while the second case can be beneficial from an environmental point of view.
The invention further relates to a combination of a support member and a collection of fibers for use in a method according to the invention as discussed above, which fibers are mutually positioned by the support member. The advantages that can be achieved with such a combination have already been explained on the basis of the explanation of the method of the invention in the various possible embodiments thereof.
In particular, it is pointed out that the fibers can be positioned in parallel rows, that the support member is band-shaped and / or that the support member comprises a possibly non-round passage for each fiber. In the latter embodiment, each fiber can extend through a passage.
Further advantageous embodiments can be obtained if each fiber has a thickened part that is located on one side of the passage and that the largest part of the length of the fiber is situated opposite the side of the passage.
A form-locked connection between the fibers and the support member can be obtained if each fiber extends through a passage such that the thickened part of the fiber hooks into at least a part of the peripheral edge of the passage in a confining zone of the passage. The thickened part can thus be accurately positioned, which promotes reliable engagement of the fiber by a fiber insertion pin during step C.
On the one hand to enable accurate mutual positioning of the fibers, more specifically of the thickened parts thereof, and on the other hand to prevent damage / distortion of the support member during step C, it is possible to design the combination in such a way that the passage has a release zone which is in communication with the confinement zone wherein the circumference of the thickened portion fits within the circumference of the passage in the release zone.
The carrier in the combination can further be provided with engagement elements which are provided in a regular pattern for engagement by engagement members of positioning means for moving the carrier and thus positioning fibers under fiber insert pins of a device according to step b.
A relatively simple embodiment can thereby be obtained if the engaging elements are formed by holes which can be engaged by teeth of positioning means.
The combination preferably also comprises an axle body around which the carrier is wound. In that case it is further preferred that the weight of the combination is a maximum of 20 kg, preferably a maximum of 15 kg, so that the combination, thus including the axle body, can be handled by a single person. A very suitable weight of the combination in question would, for example, be approximately 10 kg.
More preferably, the ratio of the weight of the fibers to the weight of the support member is at least 1: 12, preferably at least 1: 6.
As the ratio is larger, with a single combination, assuming a constant weight of the combination, fibers can be applied in a larger soil surface. The optimum ratio will also depend on whether the carrier is of the reusable type or not.
The invention also relates to a device for arranging fibers in the ground, comprising a frame movable over the ground in a direction of movement, one fiber insertion pin, displacement means for moving down with respect to the frame and for displacing the fiber insertion pin, positioning means for placing under the fiber insertion pin positioning a fiber, wherein, characteristic of the invention, the device is further provided with unwinding means for unwinding a roll of a tape-shaped carrier carrying a collection of fibers and / or winding-up means for winding the tape-shaped carrier into a roll.
For the reasons mentioned earlier, it may be advantageous if the fiber insertion pin encloses an angle with a direction parallel to the direction of movement during the pressing of a fiber into the ground. If this is desired, the device preferably comprises adjusting means for adjusting the angle enclosing the longitudinal direction of the fiber insertion pin with a direction parallel to the direction of movement. The use of such a measure can also be advantageous with a device according to the prior art. The invention therefore also relates to a device for introducing fibers into the ground comprising a frame movable over the ground in a direction of movement, one fiber insertion pin, displacement means for moving the fiber insertion pin downwards and relative to the frame, positioning means for positioning the fiber insertion pin of a fiber, the device comprising adjusting means for adjusting the angle enclosing the longitudinal direction of the fiber inserting pin with a direction parallel to the direction of movement.
Furthermore, it may be advantageous for the reasons mentioned earlier if the device has control means for controlling the speed at which the fiber insertion pin moves down and / or up depending on the resistance that the fiber insertion pin experiences due to contact with soil during the displacement of the fiber insertion pin. The use of such a measure can also be advantageous with a device according to the prior art. The invention therefore also relates to a device for arranging fibers in the ground, comprising a frame movable over the ground in a direction of movement, a number of fiber insertion pins arranged in a row extending transversely to the direction of movement, displacement means for displacing frame down and on moving the fiber insertion pins, positioning means for positioning fibers under the fiber insertion pin, the device having control means for controlling the speed at which the fiber insertion pin moves down and / or up depending on the resistance that the fiber insertion pin experiences due to contact with soil during the displacement of the fiber insertion pin.
The device can comprise a number of fiber insertion pins which are arranged in a row extending transversely to the direction of movement, the displacement means being arranged for, preferably jointly, thus simultaneously simultaneously moving the fiber insertion pins down and away from the frame.
The unwinding means and / or the winding means can be adapted to rotate the associated roller about a rotation axis, which rotation axis extends in a direction parallel to the direction of movement or in a horizontal direction just transversely of the direction of movement.
The displacement means can be arranged for synchronous displacement of the fiber insertion pins arranged in a row.
According to a further embodiment, a first part of the number of fiber insertion pins is connected to each other via a first sub-frame and a second part of the number of fiber insertion pins is connected to each other via a second sub-frame, wherein the displacement means are arranged for displacing asynchronously via the first sub-frame from causing the first part of the number of fiber insertion pins and displacing the second part of the number of fiber insertion pins via the second sub-frame.
It is possible here for the displacing means to have a first driving means for driving the first sub-frame and to have a second driving means for driving the second sub-frame or for the displacing means to have a single driving means for driving both the first sub-frame and the second sub-frame .
Application of the above-described measure related to moving the first part of the number of fiber introduction pins via the first sub-frame and moving the second part of the number of fiber introduction pins via the second sub-frame can also be advantageous in a device according to the position of the Technic. The invention therefore also relates to a device for arranging fibers in the ground, comprising a frame movable over the ground in a direction of movement, a number of fiber insertion pins arranged in a row extending transversely to the direction of movement, displacement means for displacing frame and on displacement of the fiber insertion pins, positioning means for positioning fibers under the fiber insertion pin, wherein a first part of the number of fiber insertion pins is connected to each other via a first sub-frame and in that a second part of the number of fiber insertion pins is connected to each other via a second sub-frame is connected wherein the displacement means are adapted to cause the first part of the number of fiber introduction pins to be moved asynchronously via the first subframe and to have the second part of the number of fiber introduction pins move via the second subframe.
In the case of applying a first part of the number of fiber insertion pins connected to each other via a first sub-frame and a second part of the number of fiber insertion pins connected to each other via a second sub-frame, the displacement means being arranged for asynchronously via the first moving the first part of the number of fiber insertion pins and moving the second part of the number of fiber insertion pins via the second sub-frame, it may further be advantageous if the device has control means for controlling the period of time between the starts of the downward movements of the first part of the number of fiber insertion pins and of the second part of the number of fiber insertion pins depending on the resistance that the fiber insertion pins encounter due to contact with soil during the displacement of the fiber insertion pins. The use of such a measure can also be advantageous with a device according to the prior art. The invention therefore also relates to a device for introducing fibers into the ground comprising a frame movable over the ground in a direction of movement, one fiber insertion pin, displacement means for moving the fiber insertion pin downwards and relative to the frame, positioning means for positioning the fiber insertion pin of a fiber, the device further comprising control means for controlling the period of time between the starts of the downward movements of the first part of the number of fiber insertion pins and of the second part of the number of fiber insertion pins depending on the resistance which the fiber inserts fiber insertion pins encountered due to contact with soil during the displacement of the fiber insertion pins.

Figure 18 is an isometric view of an injection unit as used in the device according to Figures 17a and 17b.
Figures 1 and 2 show a device designed as a carriage 1 for laying fibers in soil. The carriage 1 is provided with a single front wheel 2 and two rear wheels 3. Behind the rear wheels 3, carriage 1 further comprises a roller.
9. The front wheel 2 is of the steerable type. Trolley 1 is further provided with drive means comprising an electric motor for driving the rear wheels 3. Trolley 1 further comprises a housing 4. On the rear side of housing 4 a handle 5 is provided with which the front wheel 2 can be steered and in a desired direction be targeted.
A band-shaped carrier 7 is provided within housing 4 (see also figures 3 and 4). The carrier 7 can for instance be made of paper or plastic. At one end this carrier 7 is wound into a roll 6 and at the opposite end, the carrier 7 is wound into a roll 12. Roller 6 is supported by an axle body (not shown) that extends inside the central passage 8 of roller 6. The axis of the axle body extends parallel to the direction of movement 10 of carriage 1. Roller 6 is rotatable about axis in rotation direction 11, tape-shaped carrier 7 of roll 6 is unwound. In figures 2, 3, 5a and 6a it can be seen that the belt-shaped carrier 7 is subsequently wound up again into the roll 12. Roll 6 will hereinafter be referred to as unwinding roll 6 while roll 12 will be referred to as the wind-up roll 12. Also wind-up roll 12 is carried by an axle body (not shown), the axis of which extends parallel to the direction of movement 10 for carriage 1. Take-up roll 12 is rotatable about this axis. The axle body is clampingly received in the central passage 14 of take-up roller 12, so that the relevant axle body and the take-up roller 12 can only rotate jointly.
Trolley 1 comprises drive means, at least comprising an electric motor, with which the axle body associated with take-up roller 12 and therefore take-up roller 12 itself can be rotated in rotation direction 15. Energizing the electric motor will cause the tape-shaped carrier 7 to be unwound from unwinding roller 6 and wound onto winding roller 12. On the side of unwinding roller 6, carriage 1 is provided with a guide roller 16a which is freely rotatable about its axis and which extends parallel to the direction of movement 10. On the side of take-up roller 12, carriage 1 is provided with a guide roller 16b which is also freely rotatable about its axis and extends parallel to the direction of movement 10. The tape-shaped carrier 7 is wrapped between the unwinding roller 6 and the winding roller 12 around the guide rollers 16a, 16b so that the tape-shaped carrier 7 extends linearly and horizontally between them and, during the unwinding of the unwinding roller 6 and the winding up on the winding roller 12, moves in the direction of movement 18 which extending perpendicular to the direction of movement 10. It is noted, on the other hand, that the guide rollers 16a and 16b are not shown in Figure 3, so that the tape-shaped carrier 7 has a linear course between the unwinding roller 6 and the winding roller 12. Between the guide rollers 16a and 16b, carriage 1 is provided with a pair of gear wheels
17. The center lines of these gear wheels 17 are aligned with each other and extend parallel to the direction of movement 10.
The band-shaped carrier 7 is provided on its two opposite longitudinal sides with round holes 19 which are regularly spaced apart. The teeth of the two gear wheels 17 engage into operation during operation
19. It is also conceivable to provide one or both guide rollers 16a, 16b with teeth that would engage in holes 19. At least one of the gear wheels 17 is coupled to a sensor that measures the angle of rotation of the gear (s). 17 registers and thus also the number of revolutions of gear (s) 17. This sensor is coupled to an electronic control that controls the electric motor associated with take-up roller 12.
Trolley 1 further comprises a flat guide plate 21, the width of which is equal to the width of the tape-shaped carrier 7. Guide plate 21 extends directly below the tape-shaped carrier 7 in the region between unwinding roller 6 and winding roller 12, thereby ensuring guidance in use and support for the belt-shaped carrier 7. To provide space for toothings of gear wheels 17 and for any toothings of guide roller 16a and / or 16b, recesses 21 can be provided in guide plate 21 at the relevant positions.
On the side remote from guide plate 21, the band-shaped carrier 7 is provided with fibers 31 extending parallel to each other in the conveying direction 10. The fibers may be of plastic, but also of natural material such as bamboo, flax or coconut. The fibers can then consist of a number of filaments, for example six or eight, which are twisted into each other. The length of the fiber is typically 43 cm, for example. The mutual distance between the aforementioned holes 19 in the band-shaped carrier 7 is chosen such that each of the holes extends exactly between two fibers 31. In the present example, five fibers are provided between adjacent holes 19. The width of the band-shaped carrier 7 is adjusted to this length of the fibers 31 and is at least substantially equal to it. The fibers 31 are equidistant from each other and are connected to the tape-shaped carrier 7 by means of two adhesive strips 32 which are provided with respective adhesive layers. The adhesive strips 32 extend parallel to each other in the longitudinal direction of the tape-shaped carrier and adhere between the fibers 31 to the tape-shaped carrier 7. The fibers 31 are enclosed between the adhesive strips 31 on the one hand and the tape-shaped carrier 7 on the other. The adhesive strips 32 are provided close to the center of the length of the fibers 31. The relevant distance between the center of the length of the fibers 31 and the adhesive strips 32 is indicated in Fig. 4 by reference numeral 33. Exactly in the middle of the length of fibers 31, i.e. precisely between the two parallel adhesive strips 32, carrier 7 is under each fiber 31 provided with a round hole 34.
Trolley 1 is further provided with a row of fiber introduction pins 41, more specifically in this example with a row of twenty pins 41. The pins 41 extend downwardly from beam 42 to which the upper ends of the pins 41 are connected. The connection in question is releasable, so that a pin 41 can easily be dismantled and, if necessary, replaced. The row of pins 41 extends parallel to the longitudinal direction of the band-shaped carrier 7. The mutual distance between the pins 41 is equal to the mutual distance between the fibers 31. The pins 41 have an inverted V-shaped groove 43 at their lower ends .
Trolley 1 further comprises two actuators 44, such as pneumatic cylinders, with which beam 42 can be moved down and up between the upper position according to figure 5a and the lower position according to figure 6a. Shortly above the lower ends of pins 41, carriage 1 is provided with a guide beam 45 in which a guide hole 46 is provided for each pin 41. On guiding beam 45 two standing guiding rods 47 are provided at two opposite ends thereof which are aligned with the row of pins 41. The upper ends of the guiding rods 47 extend through guiding holes in beam 42, which are not shown. At positions between the pins 41, the guide beam 45 is provided with pressure elements 49. Right below the guide holes 46 in the guide beam 45, guide plates 21 are also provided for each pin 41, not further visible in the figures.
Trolley 1 functions as follows. Trolley 1 is placed on ground in such a way that at the front of trolley 1 there is a strip of soil in which fibers 31 have to be applied. Actuators 44 are then actuated for a downward and upward movement so that the fibers 31 which are located directly under the pins 41 are inserted into the ground. The inverted V-shaped lower ends 43 contribute to the downward stroke of the respective fibers 31 being properly engaged by the pins 41. During the downward movement, the lower end 43 of each pin 41 moves successively through the associated hole 34. carrier 7, in the guide hole located directly below it in the guide plate 21 and finally in the ground. The fiber 31 is thus also forced through the said holes and thereby folded double. The downward movement then ends at a position where the two ends of the fiber 31 still project a few centimeters, for example 2 cm, above the ground. During the first part of the downward movement guide bar 45 also moves downwards until the pressure elements 49 abut against the upper sides of the adhesive strips 32 and the carrier 7 clamps against the guide plate 21 because of the effectiveness of the aforementioned compression springs, because of this clamping the carrier remains 7 tightly while pressing the fibers 31 into the ground. During the upward movement of the pins 41, the fibers 31 remain behind in the ground. At the end of the upward movement the guide beam 45 moves up again and the pressure elements 49 are released from the carrier 7. The downward and upward movement of the guide beam 45 with pressure elements 49 can for instance be realized with the aid of separate actuators and / or spring members. .
The control of carriage 1 then ensures on the one hand that carriage 1 moves over the ground over a pitch, which is typically equal to the distance between adjacent fibers 31 in the direction of movement 10. On the other hand, the electric motor associated with take-up roller 12 is energized so that the tape-shaped carrier 7 is further wound onto take-up roller 12 and a new part of tape-shaped carrier 7 of unwinding roller 6 is unwound in such a way that the next twenty fibers on carrier 7 are again under the twenty pins 41 positioned. The electric motor in question is energized until the sensor associated with gears 17 has established that the required length of the belt-shaped carrier is wound onto take-up roller 12 and has been unwound from unwinding roller 6. The foregoing process is repeated for the entire strip of soil into which fibers 31 are to be applied. Subsequently, fibers can be applied in one or more adjacent strips of soil in a similar manner. It will be clear that the tape-shaped carrier 7 is provided with fibers 31 to the extent that it forms part of the unwinding roller 6 and is no longer provided with fibers 31 as far as it forms part of the winding roller 12. It is conceivable that carrier 7 can be reused after use by fibers again. 31 to apply.
It is also possible that fibers 31 are arranged in a strip of soil that is narrower than the length of a row of twenty pins 41. To this end, a part of the pins 41 can be dismantled from the beam 42 so that the length of the row of pins 41 corresponds to the desired width of the strip of soil. Subsequently, the electric motor associated with the take-up roll is energized such that each time only a length that is adjusted to the smaller number of pins 41 of the carrier 7 is wound onto take-up roll 12 and is logically unwound from the take-up roll 6.
Figures 7 and 8 relate to an alternative embodiment of belt-shaped carrier 51 with fibers 52, such as could also be used in the invention. Like belt-shaped carrier 7, the band-shaped carrier 51 is provided with holes 19 on the longitudinal edges. An important difference is that the fibers 52 extend parallel to the longitudinal direction of band-shaped carrier 51 and are provided in groups in successive rows of a number of in this example 21, fibers 52 which number corresponds to the number of fiber insertion pins of the device with which the fibers can be applied in soil. The device in question can again be designed as a car. The fiber insertion pins of this carriage are arranged in a row of twenty-one pins, the longitudinal direction of which, just as with carriage 1, extends perpendicular to the direction of movement of the carriage. However, the axes and thus the axes of rotation of the axle bodies carrying a unwinding roller and a winding roller for the belt-shaped carrier 51 are not oriented as with carriage 1 parallel to the direction of movement for the carriage, but perpendicular thereto with the respective unwinding roller and winding roller facing opposite. sides of the row of fiber insertion pins, i.e. in the direction of movement of the carriage, are located at the front and at the rear of the row of pins.
As shown in particular in Figure 8, each of the fibers 52 of a row of fibers 52 with two adhesive strips 53, 54 is connected to the tape-shaped carrier 51. The adhesive strips 53, 54 are provided just off the center of the length of each of the fibers 52. Between the two adhesive strips 53, 54 a round hole 55, similar to hole 34 in band-shaped carrier 7, is provided for each fiber 52 in the band-shaped carrier 51.
In use, the band-shaped carrier 51 is positioned below the row of fiber insertion pins such that the holes 55 are each aligned with one of the fiber insertion pins so that during the downward movement of the fiber insertion pins, they first engage a fiber 52 with their lower end and then through the holes 55 and the guide holes located thereunder move in the guide plate similar to guide plate 21 and then into the underlying ground.
The fibers 62 associated with the belt-shaped carrier 61 according to Figures 9 and 10 can be provided in the ground with the same device as that used for belt-shaped carrier 51 according to Figures 7 and 8. Unlike fibers 52 that run in a straight line, fibers 62 are formed on the carrier 51 to form a U-shape. Each of the fibers 62 has two leg parts 62a, 62b, the length of which almost corresponds to half the total length of the fiber 62, and a relatively short body part 62c which extends perpendicularly to the leg parts 62a, 62b and connects them to each other.
For each of the fibers 62 there is one in the band-shaped carrier 61
U-shaped recess 63 provided with leg parts 63a and 63b, as well as with body part 63c.
Because of the U-shaped recess 63, the band-shaped carrier 61 comprises a lip 64 for each of the fibers 62. A round hole 65 is provided in each of the lips 64. On opposite sides of the hole 65, notches 66a, 66b are provided in the leg parts 63a and 63b, on the outer sides thereof. The leg parts 62a and 62b of fibers 62 extend parallel to the leg parts 63a, 63b of the U-shaped recess 63 on the upper side of the band-shaped carrier 61. The body part 62c of fiber 62 extends on the lower side of lip 64, more specifically straight under the hole 65 of the relevant lip 64. In the transition areas between leg part 62a and body part 62c, as well as between leg part 62b and body part 62c of fiber 62, fiber 62 extends through the notches 66a, 66b. The material of the band-shaped carrier 61 has such a rigidity that lip 64 is aligned with the rest of the band-shaped carrier 61. As a result, lip 64 presses the body part 62c of fiber 62 on the underside of band-shaped carrier 61.
The fibers 62 can be applied to the soil in a manner similar to the way fibers 52 can be introduced into the soil.
The band-shaped carrier 71 according to figures 11 and 12 could be considered as an elongated blister-like package for fibers 72. A blister 73 is provided for each of the fibers 72. The fibers 72, like fibers 52 in Figures 7 and 8, extend parallel to each other and to the longitudinal direction of the band-shaped carrier 71 in groups. At the center of the length of each fiber 72, a round passage 74 is provided in each blister 73, through which a fiber insertion pin can move downwards in use and the fiber 72 located in the relevant blister 73 can engage to subsequently push it into the ground with further continuous downward movement of the fiber insertion pin.
Key-hole-shaped holes 83 are provided in the band-shaped carrier 81 according to Figs. 13a to 13d. More specifically, this keyhole shape comprises a circular part 83a and a narrowed part 83b which connect to each other and wherein the diameter of the circular part 83a is larger, for example three times as large, than the width of the narrowed part 83b. The holes 83 are arranged in rows, which rows extend perpendicular to the direction of movement of the carriage with which the fibers 82 can be arranged in the ground.
In figures 13a to 13d, only one hole 83 is shown in the respective plan view for the sake of clarity.
The fibers 82 are of a different type than described so far. Namely, fibers 82 comprise a thickened part 82a whose diameter is smaller than that of the circular part 83a but larger than the width of the narrowed part 83b. The thickened portion may be formed, for example, by knotting the fiber 82, a cured glue connecting the filaments of the fiber 82 or an annular clamping member connecting the filaments. In the initial state according to figures 13a and 14a, the thickened part 82a extends on the underside of the band-shaped carrier 81, more specifically at the narrowed part 83b of an associated hole 83. The remaining part of the fiber 82 extends from the thickened part 82a through the narrowed part 83b to the top of the carrier 81
In use, the holes 83 are positioned under associated fiber insertion pin 41 such that the circular portions 83a thereof are aligned with the fiber insertion pin 41. Then, with a pressure body 85, the thickened portion 82a is pushed from the narrowed portion 83b to the circular portion 83a as shown in Figure 13b. As a result, the thickened part 82a is aligned with the fiber introduction pin 41 which can then press the fiber 82 into the ground by means of a downward movement as shown in figures 13c and 13d. During the movement of the thickened part 82a through the pressure body, roller 84 presses the fiber 82 lightly against the carrier 82 to fix the position of fiber 82, even if the thickened part 82a is positioned at the circular part 83a of hole 83. The reliability with which the fiber 82 can be engaged by pin 41 is thus increased.
Figures 15a and 15b show at least the interior of a device designed as a carriage 101 for applying fibers into the ground. Carriage 101 has an injection unit 102 (Fig. 16c) that extends between unwinding roller 6 and winding roller 12. Injection unit 102 comprises two beams 103, 104 which are at least in line with each other in the highest position of said beams 103, 104. Injection unit 102 further comprises a row of twenty parallel fiber insertion pins 105. The upper ends of one half of directly adjacent fiber insertion pins 105 are rigidly connected to beam 103. The upper ends of the other half of fiber insertion pins 105 are rigidly connected to the other beam 104. The tape-shaped carrier 7 which is unwound in operation from unwinding roller 6 and wound onto winding roller 12 is guided under the lower ends of the fiber insertion pins 105, at least if they are in their highest position, leather of the beams 103, 104 connected in the middle of the length to the sides of the beams 103, 104 remote from fiber insertion pins 105 with a piston rod 106, 107 of a cylinder which is operated with respective servomotors 108, 109. For guiding that movement, the injection unit also includes a guide bar 110 in which guide holes are provided for each of the fiber insertion pins 105. With the aid of the two servomotors 108, 109 the beams 103, 104 and the fiber insertion pins 105 connected thereto can be moved down and up independently of each other in the longitudinal direction of the piston rods 106, 107 and of the fiber insertion pins 105. The independent control by means of the two servomotors 108, 109 make it possible, for example, to move the beams 103, 104 down with an equal speed profile but with a specific phase difference or to move the beams 103, 104 down and up with a different speed profile. Furthermore, it is possible to determine the mechanical resistance that the fiber insertion pins due to contact with the ground or at least to derive from the power demanded by the servomotors 108, 109. Depending on that determination, the speed profile of the beams 103, 104, for example, can then be adjusted and / or the phase difference between the beams 103, 104 can be adjusted. For example, with relatively soft soil into which the fiber insertion pins 105 are pressed, the downward speed may be greater and / or the phase difference may be smaller.
The injection unit 102 is tiltably provided with respect to the chassis of the carriage 101 about a virtual tilt axis that coincides with the row formed by the points where the fiber insertion pins protrude into the ground when used. For fixing a tilting position carriage 101 comprises a fixing plate 121 on opposite sides of the carriage 101 in which holes 122, 123 are provided, each of which is arranged in an arc shape. The heart of the arc shapes coincides with the virtual tilt axis. Fig. 15a shows a position in which the fiber insertion pins 105 are oriented perpendicular to the substrate over which carriage 101 is running. In Fig. 15b, the injection unit is tilted, so that the fiber introduction pins 105 are not inserted perpendicularly into the ground and, therefore, also the fibers are not inserted perpendicularly into the ground.
Figures 17a and 17b relate to an alternative injection unit 151 as it can form part of a device according to the invention designed as a carriage, for example as an alternative to injection unit 102 according to Figure 16. Injection unit 151 comprises two parallel beams 152, 153. The beams 152, 153 are provided with teeth 154, 155 on mutually facing sides. The teeth 154, 155 hold the upper ends of fiber insertion pins 156, 157. Viewed in a direction parallel to the longitudinal direction of the fiber insertion pins 156, 157, the teeth 154, 155 are alternately provided so that the fiber insertion pins 156, 157 are also alternately arranged in a row.
At the opposite ends of the row of fiber introduction pins 156, 157, two guide rods 158, 159 and 160, 161 are provided for each beam which extend through guide holes at the opposite ends of the beams 152, 153. A guide plate 162 is rigidly connected to the lower ends of the guide rods 158 to 161. In the guide plate 162, guide holes are provided for each of the fiber insertion pins 156, 157. The guide rods 158 to 161 are rigidly connected to the chassis of the carriage.
For moving the fiber insertion pins 156, 157 down and up, the injection unit comprises a double-crank axis mechanism 163. The mechanism 163 comprises for each of the beams 152, 153 with associated fiber insertion pins 156, 157 a crank 164, 165 and a connecting rod 166, 167. Crank 164 and connecting rod 166 are connected to each other via hinge 168. Crank 165 and connecting rod 167 are connected to each other via hinge 169. At the end opposite hinge 168 connecting rod 166 is connected via hinge 170 to the center of beam 152. At the end opposite hinge 169 connecting rod 168 is connected via hinge 171 to the center of beam 153. The cranks 164, 165 are rigidly connected to each other via continuous transmission 172. For the purpose of the rigid connection, the cranks 164, 165 can also be spaced apart from transmission 172, for example by means of a strip extending between hinges 168 and 169. connected. The stools 164, 165 enclose an angle with each other. The magnitude of the angle determines the phase difference between the downward and upward displacement of the beams 152, 153 and thus of the fiber insertion pins 156, 157. For driving the crank-axis mechanism 163, the injection unit 151 comprises a drive member 173 such as a servomotor which is coupled via the transmission 172 to the crankshaft mechanism 163.
Energizing the servo motor 173 causes the fiber insertion pins 156, 157 to move downward and upward starting from the situation according to Fig. 17a where the fiber insertion pins 156, 157 are in their highest position, with fiber insertion pins 156 on the one hand and fiber insertion pins 157 on the other moving. is of a phase difference corresponding to the angle between the stools 164, 165. As a result, first the fiber insertion pins 156 will be pressed into the ground and then fiber insertion pins 157. Logically, the fiber insertion pins 156 will also make the transition from the downward movement to the upward movement. and the fiber introduction pins 156 will be released above the ground sooner.
