Definitions
- the present invention relates to a device for determining the optimal position of a wood transporter with a length-adjustable gripping arm that can be rotated about an axis of rotation for reloading a load of wood in relation to a storage destination for the wood, and a system with such a device and with a sensor and a further processing unit.
- the invention further relates to a method for determining the optimal position of a wood transporter in relation to a storage target.
- logs are often transferred from one mode of transport to another mode of transport.
- the two means of transport must be brought into a position relative to each other in which it is possible to move the logs from one means of transport to the other.
- one of the means of transport which is often a log truck or truck for picking up logs, has a gripper arm that allows the log truck to be loaded and unloaded.
- Reloading often occurs either between two trucks or between a truck and a rail car suitable for holding logs.
- the truck In the case of reloading from a truck to a wagon, the truck must be brought into a position such that the reloading process is possible and the wood can be grasped with the gripper arm of the truck and placed on the wagon.
- the wood is placed by a timber transporter on a designated area on the ground, for example in a sawmill or for temporary storage, so that it can later be picked up and transported further by the same or another timber transporter.
- DE 10 2020 205 627 A1 proposes using a camera to detect round wood on a transport system and to handle it autonomously by controlling a gripper arm. In addition, it is suggested to define the storage area and detect it with a sensor. Based on this, a sequence for handling the logs or logs moved on the transport system is determined. In this way, automated unloading of a transport system is possible.
- EP 3 333 113 A1 proposes equipping a vehicle for loading objects with a detection device that can detect the surroundings of the vehicle and display it in an overview image. Furthermore, a target image can be generated which includes a target marking and is displayed in a display unit of the vehicle and is superimposed there on the overview image. When the vehicle is in a position where a target shown in the overview image matches the target marker, an optimal vehicle position is recognized.
- the US 2014/0261152 A1 discloses a system for displaying the parking position and parking direction of a dump truck, which allows the operator of an excavator to specify the parking position and direction to the dump truck in order to enable easy loading.
- the present invention relates in a first aspect to a device for determining the optimal position of a wood transporter with a length-adjustable gripping arm that can be rotated about an axis of rotation for reloading a load of wood in relation to a storage destination for the wood, with: an input interface for receiving storage information regarding the storage destination for the wood and for receiving grip point data regarding a grip point on the wood load for the gripper arm; an evaluation unit for determining the position of the storage target based on the storage information for the wood and for determining an optimal gripper arm length based on the gripping point data, the evaluation unit doing this is designed to determine a gripper arm position value for an optimal gripper arm position of the rotation axis of the gripper arm in relation to the position of the storage target from the storage information and the gripper arm length; an output interface for sending the gripper arm position value to a further processing unit.
- FIG. 1 Further aspects of the invention relate to a timber transporter and a method designed in accordance with the device, as well as a computer program product with program code for carrying out the steps of the method when the program code is executed on a computer, and a storage medium on which a computer program is stored, which when it is executed on a computer, causes the procedures described therein to be carried out.
- the device can be used to determine the optimal position of the wood transporter based on an optimal gripper arm length of the gripper arm.
- the gripper arm length is based on the gripping point data for the load stored on the transporter, which can consist of logs, wooden sticks or logs. This gripping position is usually mid-length.
- the gripping position usually reflects the center of gravity of the logs or pole-like timbers.
- the present invention therefore has the advantage that the wood transporter is positioned in relation to the storage target for the wood so that the gripper arm length for the The entire loading process, loading and unloading, can be maintained. This means that it is not necessary to adjust the length of the gripper arm.
- the gripper arm simply rotates to transfer the load from one transport system to the other transport system.
- the gripper arm length does not have to be varied during reloading, a faster loading and unloading process is possible. In addition, you can work safely because the position of the load and the gripper arm is always predictable.
- the storage destination is the place to which unloading takes place or from which the timber transporter is loaded.
- the storage target can be determined and predetermined by a single point or, if the storage target is known, by its external shape and/or dimensions. For example, if the storage target is a railway wagon, its external dimensions and contour can represent the storage target.
- the storage target can also represent the location where the center of gravity of the wood or the gripping position of the gripper arm is at the target location.
- an optimal gripper arm position of the rotation axis of the gripper arm can be determined. This makes it possible to carry out reloading operations or loading and unloading with only one rotational movement. In this way, faster reloading can take place. This is particularly important because the logs or logs are usually loaded individually or in small quantities. Therefore, frequent repetition of the gripper arm movement is necessary. Since the gripper arm length does not have to be changed due to the optimal gripper arm position, the reloading, loading or unloading process can be significantly accelerated.
- This warehouse information can be provided by a central control center and sent to Device are transmitted.
- the transmission can preferably take place wirelessly, for example via WLAN, mobile communications or other wireless signal transmission paths.
- the input interface is designed to receive sensor signals from an optical sensor.
- the sensor signals include the storage information regarding the storage destination for the wood. In this case, there is no need for a central control center. Rather, the sensor signals from the optical sensor are evaluated.
- the optical sensor is a camera that takes an image of the environment.
- the camera can preferably be mounted on the timber transporter. Just as preferably, the camera can be part of a monitoring environment for the timber transporter. The camera can be integrated in the vehicle.
- image evaluation can be carried out.
- the image can, for example, be evaluated using the AI approach in order to recognize and detect possible targets for unloading or picking up logs. It is also possible for estimation algorithms to be used or other known estimators to be used to deduce the storage target for the wood and the position of the storage target from the image data and the storage information.
- the evaluation unit is designed and set up to categorize the storage target from the storage information received.
- Different categories of storage goals can be used. For example, one category may include rail cars, another category may include log trucks or trucks with trailers that can transport logs. Another category could involve designated ground storage areas.
- An approach can also be used for detection and categorization based on artificial intelligence (Kl). Using categorization, it is possible to identify storage targets that can be transported. For example, a distinction can be made as to whether a wagon is suitable for holding logs or long pieces of wood or whether it is, for example, a closed wagon. The categorization also serves to identify storage targets that can be transported, such as wagons.
- Stock targets can be displayed in a display unit.
- the category or capacity can be displayed as an absolute value, as a percentage or as an estimate or classified in predetermined ranges.
- the position of the storage target is determined or estimated by means of the evaluation unit relative to the gripper arm position of the gripper arm.
- the gripper arm position of the gripper arm is preferably processed in longitudinal and lateral coordinates. On this basis, relationships to the other positions can be easily established. Processing is simple and requires little computational effort.
- the environment around the wood transporter or vehicle as well as the storage target can be displayed on a display unit, such as a display.
- a display available in the vehicle can also be used for this purpose.
- a wood transporter position is determined from the determined gripper arm position using the evaluation unit.
- the log truck position can be used as a target for a log truck movement.
- automated, semi-autonomous, autonomous or assisted driving of the vehicle into the optimal wood transport position can be provided.
- the position of the storage target and/or the wood transporter position are output to a further processing unit in order to further process the position data.
- the further processing unit can be, for example, a navigation system or a system for autonomous driving or semi-autonomous driving of the vehicle.
- the route can be calculated from the determined positions and an autonomous journey can be started.
- the relative position of the gripper arm and the pivot point of the gripper arm to the wood transporter is preferably taken into account.
- the gripper arm can be arranged centrally between the two sides of the vehicle. It is also possible for the gripper arm to be arranged on one side of the vehicle. The wood transporter position then results from the gripper arm position relative to the wood transporter.
- a monitoring device is included for monitoring the surroundings of the vehicle or the wood transporter.
- the monitoring device can receive position values of the sensors from the device.
- the monitoring device can be integrated into the vehicle or timber transporter.
- the monitoring device can preferably include collision monitoring in order to avoid collisions with other vehicles or people in the vicinity of the wood transporter.
- the monitoring device can also provide image-based vehicle detection as used, for example, in systems to avoid rear-end collisions. A safe distance from other vehicles that are not an unloading destination can also be stored.
- Storage targets can be set using optical sensors, e.g. B. cameras, recorded and evaluated.
- Warehouse goals can also be specified by a central control center. The specification can be based on other procedures or merchandise management programs. Higher-level goals of optimization can influence the selection of storage targets.
- the evaluation unit is preferably designed to further process the sensor signals of the imaging sensor and to determine the position of the storage target for the wood load from the sensor signals comprising the storage information. Camera images can be evaluated.
- the first free target is preferred or the driver can select a storage target individually. Further selection criteria are conceivable. They can be specified, e.g. B. from a central control center.
- the present invention is particularly suitable for the timber industry, in which long wooden sticks or round timbers are reloaded. This usually involves reloading from a timber transporter or truck with a trailer capable of transporting timber or a semi-trailer to another vehicle or to railway wagons that are suitable for transporting timber.
- the invention is also suitable and applicable for other elongated or rod-shaped or tubular objects or loads that are loaded individually or in small quantities.
- the invention is particularly suitable for vehicles that have a gripper arm.

- the sensor 22 supplies sensor signals with storage information regarding the storage destination for the wood to be loaded.
- a further processing unit 26 is connected to the output interface 16, which can be, for example, an ECU (Electronic Computing Unit) of a vehicle.
- the further processing unit 26 can include a navigation unit or a navigation system as well as a system for autonomous or semi-autonomous driving and other vehicle systems that further process the gripper arm position values for the gripper arm position of the rotation axis of the gripper arm.
- values relating to the position of a vehicle can also be transmitted to the further processing unit 26 by means of the output interface 16.
- the timber transporter position data can, for example, be fed to a navigation system in order to autonomously drive the vehicle to a desired target position or to support the driver in finding this position.
- the optimal position of the wood transporter can be displayed graphically on a display, for example a display of a navigation system. It is also possible to use a surround view display of the vehicle, including its surroundings, to show the destination, i.e. the optimal position of the wood transporter, for reloading wood. An optimal route can be calculated and shown on a display.
- the system 20 may also include a monitoring device 28 connected to the device 10 via an optional monitoring interface 18.
- the system 20 can be part of a vehicle or timber transporter 30, with parts of the system 20 also being able to be integrated into existing electronic units of the vehicle or timber transporter 30.
- the typical ECU of a vehicle can calculate and process the processing of the image data, the detection of unloading destinations, the calculation of the optimal position or final position of the wood transporter, especially in relation to the storage destination.
- the calculation of display information for the optimal final position of the vehicle is also possible selected or preferred storage destination can take place in the ECU.

- Fig. 3 shows a wood transporter 30 with a length-adjustable gripping arm 32, which is rotatable about an axis of rotation 34.
- a load of wood 36 which includes individual logs 38, is stored on the wood transporter 30.
- a gripping point 40 of the logs 38 results from the center of gravity of the logs 38, which is in the middle of the longitudinal extent of the logs 38.
- a distance 42 between the axis of rotation 34 and the gripping point 40 forms the gripper arm length 44, which is set for the gripper arm 32 so that it can grip and reload a log 38. In the present case, the reloading should take place from the wood transporter 30 to a wagon 46 of a train.
- FIG. 3 shows two wagons 46a and 46b capable of transporting wood, the wagon 46a being loaded with only one log 38 and thus having free transport capacity.
- the wagon 46b on the other hand, is loaded with a complete load of wood 36 and cannot accommodate any more logs. It therefore has no further transport capacity and is therefore classified as occupied.
- a storage destination In order to reload the wood load 36 from the wood transporter 30 onto one of the wagons 46, a storage destination must first be recognized. This storage target 48 is formed by the wagon 46a since it is only partially occupied. For the reloading process, the wood transporter 30 must be moved into an optimal wood transporter position 50. This is the optimal position for reloading the wood load 36 from the wood transporter 30 on a wagon 46, whereby the gripper arm length 44 can remain constant. The wood transporter 30 is moved on a trajectory 52 to the wood transporter position 50.
- the target position After the target position is calculated as the timber transporter position 50, it can be displayed in the camera image on a display in the timber transporter 30. Alternatively, additional images from other cameras can be used, for example to show a surround view image into which the target position is projected.
- the path to the target position i.e. the trajectory 52 to the wood transporter position 50, is constantly calculated by a navigation system. The closer the wood transporter 30 is to the destination, the more accurately the trajectory 52 can be calculated so that the vehicle, i.e. the wood transporter 30, reaches the wood transporter position 50 as the desired destination and in the desired orientation.
- An assistance for steering can preferably be displayed or carried out at any time, for example a correction angle for the wood transporter 30 can be determined and specified.
- the lane taken by the vehicle it is also possible for the lane taken by the vehicle to be shown. It is also conceivable to show the trajectory as an overlay in the direction of travel as long as the target position is still in the field of vision. Alternatively, a surround view can be used if the vehicle is already very close (less than 20 m) to the target position.
- a warning can advantageously be issued if the vehicle is positioned in such a way that the wood transporter position 50 can no longer be reached in forward gear alone, taking into account a vehicle model. The driver can then be asked to either maneuver or change the steering angle. When maneuvering, a minimum length for a reverse trip can be recommended in order to be able to make a successful new attempt to reach the log truck position 50 in relation to the storage target 48.
- a camera 24 of the wood transporter 30 is used to detect the storage target 48 in the form of a wagon 46.
- the camera 24 supplies sensor signals that contain storage information about the storage target 48.
- the image of the camera 24 is searched for suitable storage targets 48, such as wagons 46, other wood transporters 30 or storage areas such as piles of wood, for example using an AI approach.
- suitable storage targets 48 such as wagons 46, other wood transporters 30 or storage areas such as piles of wood, for example using an AI approach.
- the Recognition of a wagon 46 as a storage target 48 can be carried out, for example, using known image recognition methods.
- the device according to the invention which is integrated in the wood transporter, is set up to distinguish between wagons 46 capable of transporting wood and other wagons, such as containers or closed wagons, and to carry out a corresponding categorization.
- the evaluation of the images from the camera 24 can not only categorize the identified storage targets 48, but also classify them according to occupancy capacities. By dividing the storage targets 48 into free, partially occupied or occupied, it can be guaranteed that the driver is only offered storage targets 48 that are free or partially occupied, i.e. have a wood holding capacity.
- images of the vehicle surroundings can also be recorded by the camera 24, so that other vehicles in the vicinity of the timber transporter 30 can be recognized.
- image-based vehicle detection it is possible to perform image-based vehicle detection to avoid collisions.
- a safety distance can be implemented for other vehicles that are not a dumping destination.
- FIG 4 shows a situation in which the log transporter 30 is arranged in the optimal log transporter position 50.
- the gripper arm 32 To reload logs 38 from the wood transporter 30 onto the wagon 46 categorized as partially occupied, it is sufficient for the gripper arm 32 to simply perform a rotational movement in the direction of the arrow 54. In this way it is possible to place logs 38 on the wagon 46 without changing the gripper arm length 44. This enables quick and safe unloading.
- the optimal wood transporter position 50 depends on the optimal gripper arm position and the axis of rotation 34 of the gripper arm 32. Depending on the position of the gripper arm 32 on the wood transporter 30, the wood transporter position 50 is determined from the gripper arm position 56. In the present case, the gripper arm 32 and its axis of rotation 34 is arranged centrally between the two sides of the wood transporter 30. From the stored vehicle data and the relative position of the axis of rotation 34 to the wood transporter 30, the gripper arm position 56 can be inferred from the wood transporter position 50.
- a minimum distance 58 must be maintained, which is defined here between the left outside of the wood transporter 30 and the outside of the wagon. This minimum distance 58 is also shown in FIG. 3.
- a position is now sought for the gripper arm 32 or its axis of rotation 34, in which a circle 60 is formed, the radius of which is the gripper arm length 44.
- the center of the circle 60 is the axis of rotation 34.
- the wood transporter 30 must now be positioned so that a storage target 48 lies on the circle 60.
- the storage target 48 is preferably formed by the center of gravity of the logs 38, the center of gravity corresponding to the gripping point 40. This results in two storage targets 48 according to FIG. 5, with one storage target 48a on the wagon 46a and the other (48b) on the wagon 46b.
- the storage target 48a on the wagon 46a is selected because the angle of rotation a of the gripper arm 32 is smaller and wood can therefore be transferred more quickly from the wood transporter 30 to the wagon 46.
- a preferred embodiment provides that free unloading targets, i.e. storage targets 48, are first recognized using the camera 24.
- the first free storage destination 48 or a storage destination selected by the driver of the wood transporter 30 are then used for the reloading process.
- the position of the storage target 48 relative to the log truck 30 is preferably estimated using the lateral and longitudinal coordinates relative to the log truck 30. The estimate can be made, for example, based on the size of the storage target or the wagon 46, assuming that the wagon 46 has a standard size that is known.
- the position of the storage target 48 can be estimated using image-based 3D reconstructions. It is also possible to infer the distance by recognizing the railway tracks 62 on which the wagon 46 is positioned. This will assuming a standard track size and a standard spacing.
- the position in the 3D image can be inferred.
- a lateral distance is calculated along the longitudinal axis to the storage target 48.
- This minimum distance 58 can be defined based on occupational safety requirements.
- the left side of a target lane for the timber transporter 30 or the vehicle can be defined.
- the right line of the target track and the center on which the axis of rotation 34 of the gripper arm 32 lies, at least when the gripper arm is arranged centrally are also calculated.
- a circle 60 with the radius R can alternatively be defined around the recognized storage target 48 of the wagon 46a as the selected storage target, the radius corresponding to the gripper arm length 44.
- the wood transporter is now brought into a position in which the axis of rotation 34 lies on the circle 60.
- the position on the circle is selected at which the angle of rotation a of the gripper arm 32 is as small as possible.
- the storage target 48a on the wagon 46a can be selected as the center of a circle 60 with a radius corresponding to the gripper arm length.
- the wood transporter position 50 must then be selected so that the axis of rotation 34 of the gripper arm 32 is located on the circle.
- FIG. 6 shows a situation in which a log truck 30 is arranged in the optimal log truck position 50 relative to the storage target and the wagons 46. An unloading process for unloading the load of wood 36 from the wood transporter 30 can begin.
- the wood transporter 30 with a gripper arm 32 can be used for the reloading process.
- the vehicle 64 must be brought into an optimal target position 66 so that the wood load 36 can be optimally loaded from the vehicle 64 to the wagon 46 without changing the gripper arm length 44 can be done.
- a circle 60 with a radius that corresponds to the gripper arm length 44 is drawn around the axis of rotation 34 of the gripper arm 32 of the wood transporter 30.
- the gripping point 40 of the logs 38 on the vehicle 64 must now also be on the circle 60.
- a target position is used in which the vehicle 64 is positioned as close as possible to the wood transporter 30 in order to keep the angle of rotation for the gripper arm 32 as small as possible. A minimum distance of 58 can also be taken into account.
- the position of the storage target 48 is defined by a central control center and transmitted to the device 10 of the wood transporter 30.
- the position can be in the form of GPS data, for example.
- Storage targets and storage targets 48 no longer have to be recognized, but are predetermined.
- the unloading destination or storage destination 48 is selected, which is closest to the current position of the wood transporter 30.
- a strategy can also be used here, with which partially filled wagons 46 are loaded first and then free wagons 46 are loaded.
- Fig. 7 shows a schematic representation of the method according to the invention for determining the optimal position of a wood transporter with a length-adjustable gripper arm 32 which can be rotated about an axis of rotation 34 for reloading a load of wood 36 in relation to a storage target 48 for wood.
- the procedure includes the following steps:
- a first step S10 of receiving storage information regarding the storage target 48 for wood either sensor data from a sensor 22 is evaluated or storage information from a control center is used.
- a step of receiving S12 of gripping point data data regarding a gripping point 40 on the wood load 36 is used for the gripping arm 32.
- Another step of determining S14 involves determining the position of the storage target 48 based on the storage information for the wood.
- the method includes a further step of determining S16 an optimal gripper arm length 44 based on gripping point data of the gripping point 40 and a step of determining S18 a gripper arm position value for an optimal gripper arm position 56 of the rotation axis 34 of the gripper arm 32 in relation to the position of the storage target 48 from the storage Information and the gripper arm length 44.
- a further method step relates to sending S20 of the gripper arm position value to a further processing unit 26 of the system according to the invention.
- the process can be expanded with further steps.
- An optional step S22 of determining a wood transporter position 50 takes place from the gripper arm position 56.
- a step of taking S24 into account a minimum distance 58 to the position of the storage target 48 when determining the wood transporter position 50 follows, as does a step S26 of using the wood transporter position 50 as a target for a movement of the log transporter 30.
- a step of outputting S28 of the log transporter position 50 for further processing or for a visual display completes the optional method.
