    DK 2020 70461 A1 1 A device and a method for filling gabions with stones
    TECHNICAL FIELD The present invention relates to a device for filling gabions with stones. The invention also relates to a method for filling a gabion with stones with a device according to the invention. The term “stones” is to be seen in the broad sense and includes a number of bodies of crushed rock. The size distribution and the mean stone size may differ from case to case. The term gabion refers to a cage suitable for housing stones, whereby gabions are suitable for the construction of various types of installations, practical as well as purely aesthetic,
    BACKGROUND OF THE INVENTION Contemporary filling of gabions is done with a front end loader or the like which is to used for dropping stones (crushed rock) from above into the gabion. In order to ensure that, at a later stage, when using the filled gabion, the packing degree of the stones is not altered due to subsequent movements of the stones relative to each other, the filled gabions are placed on a shaking table. Through the movement of the shaking table, the stone filling is shaken so that a degree of packing is achieved where the probability of further packing of the stones is small.
    DK 2020 70461 A1 2 After the filling is completed, a grid-shaped lid is placed on top of the gabion and sewn against the latter so that a closed cage is formed.
    A problem with prior art is that the filling of the gabion itself is difficult to control and that voids tend to be generated in parts of the gabion, which voids can later lead to a change of position of stones and change of the packing degree in the gabion. The use of the shaking table solves the problem to some extent, but not always to the extent that would be desirable. It is therefore an object of the invention to propose a device and a method for filling a gabion which solves or reduces the above- mentioned problem.
    SUMMARY The object of the invention is solved with a device for filling gabions with stones, characterized in that it comprises - at least one conveyor belt, which is formed by an endless belt extending around two rollers, the conveyor belt having a longitudinal direction in the direction from one of the rollers to the other of the rollers, - a first drive device for driving at least one of said rollers, - a feeder, arranged above the conveyor belt and having a lower opening facing the conveyor belt, - a gabion carrier configured to carry a gabion, wherein the gabion carrier is movably arranged in a direction parallel to the longitudinal direction of the conveyor belt, and
    DK 2020 70461 A1 3 - a second drive device for driving the gabion carrier reciprocatingly in said direction in the region of one end of the conveyor belt.
    The gabion carrier is thus arranged at level below the conveyor belt and the gabion will move back and forth, i.e. reciproctaingly, below an end of the conveyor belt where stones delivered by the conveyor belt will fall of from the conveyor belt down into the moving gabion.
    According to one embodiment, the feeder is a funnel, the larger opening of which forms an upper opening to enable the release of stones into the funnel via the upper opening.
    According to one embodiment, the device comprises a sensor configured to sense the degree of filling of a gabion provided on the gabion carrier.
    According to one embodiment, the sensor comprises a sonar arranged to sense a distance to an upper surface of a filling of stone in a gabion arranged on the gabion carrier.
    According to one embodiment, the sensor is operatively connected to the first drive device, and the first drive device is configured to stop driving the conveyor belt when it receives input from the sensor indicating that the degree of filling is equal to or above a predetermined value.
    According to one embodiment, the second drive device comprises a hydraulic drive device with a pressure controlled
    DK 2020 70461 A1 4 valve adapted to reverse the drive direction of the second drive device upon arrival at each of two opposite end positions in which the pressure in the valve reaches a predetermined threshold value. .
    According to one embodiment, the second drive device has a stroke between two opposite end positions corresponding to the length of a gabion in said longitudinal direction in a position when the gabion is carried by the gabion carrier and is being filled with stones falling from one end of the conveyor belt. The drive device is advantageously arranged to change the driving direction when one end of a gabion placed on the gabion carrier is in the region of the end of the conveyor belt, to which stones are delivered by the conveyor and fall down therefrom, so that filling takes place over the entire length of the gabion. According to one embodiment, the gabion carrier is provided with a shaking device for inducing a shaking motion of the gabion carrier.
    In one embodiment, the shaking device comprises an unbalance motor connected to the gabion carrier. According to one embodiment, the device comprises - a second gabion carrier configured to carry a gabion, the second gabion carrier being movably arranged in a direction parallel to the longitudinal direction of the conveyor belt at a second end of said at least one conveyor belt, opposite to the end of the at least one conveyor belt at which the first gabion carrier is disposed, and
    DK 2020 70461 A1 - a third drive device for driving the second gabion carrier reciprocatingly in said direction in the region of said second end of the at least one conveyor belt.
    5 In one embodiment, the gabion carrier comprises a cassette consisting of a bottom and four walls, and a bottom plate. At least two of the walls are articulated, lockable and openable by pivoting. The bottom of the cassette is screwed against the bottom plate and said bottom and the bottom plate are separated by rubber pads or a rubber molding. The bottom plate is arranged to slide on guides defined by a frame. According to one embodiment, the device comprises - a second conveyor belt, arranged adjacent, parallel to and in alignmnent with the first conveyor belt and formed by a second endless belt extending around two rollers, the first gabion carrier and the second gabion carrier being disposed at opposite, remote ends of the first conveyor belt and the second conveyor belt, respectively, and the device comprises - a fourth drive device for driving at least one of said rollers, around which the second endless belt extends, in an opposite direction relative to the direction in which the first drive device is arranged to drive the first endless belt.
    In one embodiment, the lower opening of the feeder faces both the first and second conveyor belts in the region of adjacent ends of the first and second conveyor belts.
    DK 2020 70461 A1 6 The object of the invention is also solved by a method for filling a gabion with stones with a device according to the invention, the method comprising the steps of: - positioning a gabion on a gabion carrier associated with the device, - insertion of stones into the feeder via an upper opening thereon; - driving the at least one conveyor belt so that said stones are conveyed to one end of the conveyor belt and fall off from it at said end, - driving the the gabion carrier carrying said gabion reciprocatingly at said end with a stroke of the reciprocating movement corresponding to the length of the gabion in the longitudinal direction (x) of the conveyor belt.
    According to one embodiment, the method also includes the steps of - sensing the degree of filling of the gabion with said stones, and, as a response to the filling degree having reached a predetermined value, - stopping the drive of the conveyor belt. According to one embodiment, the reciprocating driving of the gabion carrier continues one or more times after the conveyor belt has been stopped in response to the degree of filling having reached the predetermined value, wherein the driving of the conveyor belt is resumed if the sensor thereby senses that the filling degree, due to a change in the degree of packing in the gabion, has again dropped below the predetermined value.
    DK 2020 70461 A1 7 According to one embodiment, the method further comprises the step of shaking the gabion carrier with the shaking device as the gabion carrier is moved reciprocatingly.
    Further features and advantages of the invention will become apparent from the following detailed description of embodiments.
    BRIEF DESCRIPTION OF THE DRAWING Fig. 1 is a side view showing a device according to the invention for filling a gabion; Fig. 2 is a side elevational view, Fig. 3 is an end view of the device, and Fig. 4 is a perspective view showing the device of Figs. 1-3.
    DETAILED DESCRIPTION Fig. 1 shows a device according to the present invention for filling gabions with stones. The device comprises a first conveyor belt 1 and a second conveyor belt 2. The first conveyor belt 1 is formed by a first endless belt 4 extending around two rollers 5, 6, the conveyor belt having a longitudinal direction x in the direction from one roller 5 towards the second roller 6. The second conveyor belt 2 is arranged adjacent, parallel to and in alignment with the first conveyor belt 1 and formed by a second endless belt 7 extending around two rollers 8, 9.
    DK 2020 70461 A1 8 The first and second conveyor belts 1,2 are similarly designed and provided with similar equipment for filling gabions placed on gabion carriers arranged at opposite remote ends of the first and second conveyor belts 1, 2. For convenience, only the first conveyor belt 1 and its associated parts are described in detail. It should be realised that the second conveyor belt 2 and its associated parts preferably are arranged in a corresponding way. The first conveyor belt 1 has a first drive device 10, preferably an electric motor, for driving at least one of said rollers 5, 6 around which the first endless belt 4 extends. In the example shown, the first drive device 10 is integrated into the hub of one roller 5. The device further comprises a feeder in the form of a funnel 11, arranged above the first conveyor belt 1 and having a lower opening facing the conveyor belt 1. A first gabion carrier 12 is arranged at a first end of the first conveyor belt 1 and configured to carry a gabion, whereby the first gabion carrier 12 is movably arranged in a direction parallel to the longitudinal direction of the conveyor belt x. The gabion carrier comprises a bottom on which a gabion can stand, and four sidewalls, which encloses the the gabion and forms an outer support surface for the latter. Conveniently, at least two of the sidewalls are openable or detachable to enable easy positioning of a gabion on the gabion carrier and easy removal of the gabion from the gabion carrier.
    The device further comprises a second drive device 13 for driving the first gabion carrier 12 recprocationgly in said direction x in the region of the first end of the first conveyor belt 1. The second drive device 13 comprises a hydraulic drive device, comprising a piston arranged in a cylinder, with a pressure-controlled valve,
    DK 2020 70461 A1 9 arranged to reverse the drive direction of the second drive device 13 upon reaching each of two opposite end positions in which the pressure in the valve reaches a predetermined threshold value. The second drive device 13 has a stroke between the two opposite end positions corresponding to the length of a gabion in said longitudinal direction x in a position when the gabion is carried by the gabion carrier 12 and is being filled with stones falling from one end of the conveyor belt 1. The second drive device 13 is arranged to change the driving direction when one end of a gabion placed on the gabion carrier 12 is in the region of the end of the conveyor belt 1, so that filling takes place over the entire length of the gabion. The Gabion carrier 12 comprises a cassette consisting of a bottom 22 and four walls 23, 24, 25, 26, and a bottom plate 27 (see Fig. 4). At least two of the walls are articulated, lockable and openable by pivoting. The bottom 22 of the cassette is screwed against the bottom plate 27 and the bottom and bottom plate are separated by rubber pads or a rubber strip (not visible in the drawing). The bottom plate 27 is arranged to slide on guides defined by a frame 21.
    The device further comprises a sensor 14 configured to sense the degree of filling of stones of a gabion provided on the gabion carrier 12. In the described embodiment, the sensor comprises a sonar arranged to sense a distance to an upper surface of a filling of stone in a gabion. arranged on the gabion carrier 12. The sensor 14 is arranged on a hinged, pivotal arm and arranged above and near the end of the conveyor belt where the gabion carrier 12 is arranged to be moved back and forth, i.e. move reciprocatingly, while allowing stones to fall from the conveyor belt 1 into the gabion placed on the gabion carrier 12. Since the
    DK 2020 70461 A1 10 stroke length of the gabion carrier 12 corresponds to the length of the gabion and the drive device 13 is arranged to change driving direction when an end of a gabion placed on the gabion carrier 12 is in the region of the first end of the conveyor belt 1, the sensor 14 will be able to sense the degree of filling along the whole length of the gabion, even if the sensor is fixed in its position.
    The sensor 14 is operatively connected to the first drive device 10 and the first drive device 10 is configured to stop driving the conveyor belt 1 when it receives input from the sensor 14 indicating that the degree of filling is equal to or above a predetermined value.
    The second drive device 13 is arranged to continue to drive the gabion carrier 12 back and forth several times even after the sensor 14 indicates that the predetermined value of the filling rate has been reached.
    The sensor 14 is configured to continue its measurement and if it senses that the filling degree, due to change in the packing degree in the gabion, has dropped below the predetermined value, a signal from the sensor 14 is given to the first drive device 10, wherein the first drive device 10 is configured to resume the drive of the conveyor belt 1. According to an example, the second drive device 13 is manually controlled, and an operator is responsible for inactivating it for a certain time or a certain number of movement cycles for the gabion carrier 12 after that the sensor 14 has detected that the predetermined value of the degree of filling has been achieved and the first drive device 10 has stopped driving the conveyor belt 1.
    DK 2020 70461 A1 11 The device further includes a shaking device 15 for inducing a shaking motion of the gabion carrier 12. In the example shown, the shaking device 15 includes an imbalance motor connected to the gabion carrier.
    The degree of imbalance of the motor and its operating frequency are adjustable and can thus be adapted to different conditions, for example different rock sizes or rock size distributions.
    The shaking device 15 may be separately controlled or connected to the second drive device 13 so that it is automatically activated when the second drive device 13 is active.
    As previously mentioned, the device also comprises a second conveyor belt 2, a second gabion carrier 16 associated therewith, configured to carry a gabion, the second gabion carrier 16 being movably arranged in a direction parallel to the longitudinal direction of the conveyor belt x at an end of the second conveyor belt, opposite the first end of the first conveyor belt 1 at which the first gabion 12 carrier is disposed.
    A third drive device 17, which in its function and design corresponds to the second drive device 13, is arranged for driving the second gabion carrier 16 reciprocatingly in said direction in the region of said said end of the second conveyor belt 2. The device also includes a fourth drive device 18, which in its function and design corresponds to the first drive device 10, for driving the second conveyor belt 2. A second sensor 19, which in its function corresponds to the first sensor 14, is arranged at the end of the second conveyor belt 2 where the second gabion carrier 16 is arranged to be reciprocated.
    The second sensor 19 interacts with the fourth drive device 18 in a similar manner as the first sensor 14 interacts with the first drive device 10. The lower opening of the
    DK 2020 70461 A1 12 funnel 11 faces both the first and second conveyor belts 1,2 in the region of adjacent ends of the first and second conveyor belts 1, 2. A second shaking device 20, in its function and design corresponding to the first shaking device 15, is correspondingly connected to the second gabion carrier 16. All of the above-described parts of the device are advantageously connected directly or indirectly to a frame 21. The frame 21 preferably forms guides on which the respective gabion carrier 12, 16 is arranged to slide or roll to perform its reciprocating movement.
    The first conveyor belt 1 has a length (extending in the direction of x) which substantially corresponds to the length of the first gabion carrier 12, and the second conveyor belt 2 has a length substantially corresponding to the length of the second gabion carrier 16. This results in a very compact construction.
    The alternative to having two conveyor belts is to have only one conveyor belt having reversible drive in two different directions, which can thus be used for alternatingly filling a first and a second gabion carrier, disposed at opposite ends of this single belt.
    A method of filling a gabion with stones with a device according to the invention comprises the steps of: - positioning a gabion on the first gabion carrier 12, - inserting stones into the feeder 11 via an upper opening thereon; - driving the first conveyor belt 1 so that said stones are transported towards one end of the first conveyor belt 1 and fall off from it at said end,
    DK 2020 70461 A1 13 - driving the gabion carrying gabion carrier 12 reciprocatingly below said end, with a stroke of the reciprocating movement corresponding to the length of the gabion in the longitudinal direction of the conveyor belt x, whereby the gabion carrier is caused to change its direction when one end of the gabion is in the region of the end of the conveyor belt 12 from which the stones fall, so that the stones constantly fall into the gabion. The method also includes the steps of sensing, by means of the first sensor 14, the degree of filling of the gabion with said stones, and, in response to the filling having reached a predetermined value, stopping the drive of the first conveyor belt
    1.
    In one embodiment, the driving operation of the first gabion carrier continues back a predetermined number of times after the conveyor belt is stopped in response to the reaching of the pre- determined degree of filling, and the driving of the conveyor belt resumes if the sensor then senses that the degree of filling, due to change of the packing ratio in the gabion, once again has dropped below the predetermined value.
    In one embodiment, the method further comprises the step of shaking the gabion carrier with the shaking device as the gabion carrier is moved recprocatingly back and forth.
    The gabion is considered full after the operation of the first gabion carrier reciproctaiongly has occurred one or more times after the conveyor belt has been stopped without the sensor thereby sensing that the filling degree due to change in the
    DK 2020 70461 A1 14 gabion packing rate has again fallen below the predetermined value.
    The gabion is then removed from the first gabion carrier 10 and a grid-shaped lid is attached on top of the gabion.
    When filling of a first gabion via the first conveyor belt is completed, the corresponding filling of a second gabion via the second conveyor belt 2 is started.
    In this way, alternate filling of gabions can take place.
    Alternatively, it is also possible to fill first and second gabions in parallel by simultaneously driving the first conveyor belt 1 and the second conveyor belt 2.
