Definitions

  • the invention relates to a device for emptying garbage bins into a collecting container of a garbage truck, said device comprising:
  • Such a device is known from for example US 5004392 , which discloses mechanical barrier means formed as arms, which are pivotably arranged to the mounting frame.
  • a switch detects when the arms are pivoted in a horizontal position such that the arms physically prevent a person from stepping sideways into the danger zone. If the switch is actuated the automatic control of the at least one lifting frame by the controller is allowed.
  • a disadvantage of these mechanical barrier means is that also the operator is prevented from stepping sideways into and out of the danger zone even when no danger is present at the specific moment. This occurs for example when the operator brings a garbage bin towards the at least one lifting frame or when the operator takes a garbage bin from the at least on lifting frame.
  • the danger is mainly present when the lifting frame has a garbage bin in the second position to empty the bin into the tailgate of the garbage truck, high in the air, and then moves the garbage bin back towards the ground, towards the first position.
  • the lifting frame has a garbage bin in the second position to empty the bin into the tailgate of the garbage truck, high in the air, and then moves the garbage bin back towards the ground, towards the first position.
  • said person could get seriously injured.
  • Another disadvantage of the mechanical barrier means according to the prior art is that when the arms are in the horizontal position, the length of the garbage truck is increased.
  • a garbage truck typically has already a large length behind the rear axles due to the mounted device for emptying garbage bins into a collecting container of a garbage truck. This causes the back of the truck to swing out,when the truck makes a turn. With the mechanical arms in horizontal position even further increasing the length behind the rear axles, the maneuverability of the truck is further decreased.
  • the barrier means comprise on each side of the center plane a monitoring sensor, which monitoring sensor monitors a corresponding monitoring area extending in at least a monitoring plane, which monitoring area extends outside of the danger zone; and wherein the controller reads both monitoring sensors in order to stop movement, in particular movement towards the first position of the at least one lifting frame when an object is detected within the monitoring area.
  • the barrier means are provided by monitoring sensors, which are read by the controller. So, if the controller controls the at least one lifting frame from the second position downwards to the first position and the controller detects with the monitoring sensors that an object passes the monitoring area into the danger zone, the motion of the at least one lifting frame is stopped immediately, such that possible harm to a person or object by a descending lifting frame with garbage bin is prevented.
  • the at least one lifting frame By using monitoring sensors there is no mechanical barrier present, such that, depending on the status of the at least one lifting frame, an operator can easily move sideways from and towards the device. So, if the at least one lifting frame is without any garbage bins and waiting in the first position, the operator is allowed to step in sideways into the danger zone with a garbage bin and position the garbage bin in the holding means. When the garbage bin is emptied and the at least one lifting frame returns into the first position, the operator may take the garbage bin and step sideways outside of the danger zone.
  • monitoring sensors is also of benefit for the length of the garbage truck. As no physical parts provide any longer the barrier means, the barrier means will no longer have any impact on the length of the garbage truck, which swings out, when the garbage truck makes a turn.
  • the normal vector of the monitoring plane has a directional component parallel to the normal vector of the center plane.
  • the normal vector of the monitoring plane is parallel to the normal vector of the center plane.
  • the center plane When the device is installed on a garbage truck, the center plane will be parallel to the longitudinal plane of the garbage truck.
  • the longitudinal plane is the vertical plane, which divides the truck through the longitudinal axis into the left side and the right side of the truck.
  • the monitoring plane will thus in use be parallel to the center plane or at least diverge from the center plane and away from the truck.
  • the monitoring plane is in use vertical, but could also be somewhat tilted, but certainly not horizontal.
  • the monitoring sensor comprises at least two spaced apart proximity sensors, such as an ultrasonic sensor or a laser sensor, each proximity sensor having a detection direction positioned in the monitoring plane and wherein the detection directions of the at least two spaced apart proximity sensors are parallel.
  • Proximity sensors typically have a limited range in which the sensors can detect the presence of an object. This range could preferably be adjusted to a distance suitable to detect sideways entrance into the danger zone.
  • the distance between the detection directions of the two most spaced apart proximity sensors of the at least two spaced apart proximity sensors is at least 10 centimeters.
  • the monitoring sensor comprises a radar or lidar device, which monitors any proximity within the monitoring area.
  • Radar techniques which are also used in lidar, have the ability to scan a more or less sector shaped area and detect whether an object is present in said sector shaped area. Radar techniques also allow to measure the distance between the object and the sensor and this allows to set a maximum detection distance, which is of advantage to tune the sensor to the size of the danger zone.
  • the monitoring area is a 3D shaped area.
  • the 3D shaped area allows for the controller to "see” an object approaching the danger zone. This allows for the controller to take precautionary measures, such as already reducing the speed of the movement of the at least one lifting frame.
  • the invention also relates to a combination of a garbage truck having a collecting container and a device according to the invention, wherein the device is mounted with the mounting frame to the tailgate, and wherein the center plane is parallel and preferably coincides with the longitudinal plane of the garbage truck.
  • the longitudinal plane of the garbage truck is the vertical plane through the longitudinal axis of the truck, which splits the truck in the left side and the right side.
  • a further embodiment of the combination according to the invention comprises further at least one garbage bin, which garbage bin is held by the holding means of at least one lifting frame.
  • Figure 1 shows a schematic side view of an embodiment of a combination according to the invention.
  • Figure 2 shows a perspective view of an embodiment of the device according to the invention.
  • Figures 3A and 3B show a schematic side and top view of the device according to figure 2 .
  • Figures 4A and 4B show a schematic side and top view of a second embodiment of the device according to the invention.
  • Figure 1 shows a schematic side view of an embodiment of a combination 1 according to the invention.
  • the combination 1 has a garbage truck 2 with a collecting container 3 and a device 4 for emptying garbage bins 5 into the tailgate 6 and collecting container 3 of the garbage truck.
  • the device 4 has a mounting frame 6 to which two lifting frames 7 with holding means 8 are arranged.
  • the holding means 8 are provided with known clamping means to grab a garbage bin 5 as well as a sensor, such as a switch, to detect whether a garbage bin 5 is positioned within the reach of the respective holding means 8.
  • Figure 1 shows one of the lifting frames 7 in the lower, first position P1 and the other lifting frame 7 in the upper, second position P2.
  • the envelope of both lifting frames holding a garbage bin 5 being moved between the first position P1 and the second position P2 form the danger zone D.
  • Figure 2 shows that on either side of the lifting frames 7 with holding means 8, a pair of proximity sensors 9, 10 are provided, which each border a monitoring area 11.
  • the proximity sensors 9, 10 each have a detection direction R, which are in this embodiment spaced apart and parallel to each other, such that a monitoring area 11 is bordered by the two proximity sensors 9, 10 of the pair.
  • the monitoring areas 11 extend on either side and outside of the danger zone D, such that when an object or person moves sideways, in the direction S, into the danger zone D, the proximity sensors 9, 10 will detect the person and the controller could act accordingly, more particularly by stopping the movement of the two lifting frames 7.
  • the device according to the invention has a controller, which controls all movements of the device according to the invention, such as the holding of a garbage bin 5, the movement of each lifting frame 7 as well as other movements of the device, and the controller monitors different sensors in the device and the status of control buttons on a control panel.
  • a controller which controls all movements of the device according to the invention, such as the holding of a garbage bin 5, the movement of each lifting frame 7 as well as other movements of the device, and the controller monitors different sensors in the device and the status of control buttons on a control panel.
  • Such general control of the device is known from the prior art.
  • Figure 3B shows the center plane C to which the two monitoring areas extend parallel.
  • FIGS 4A and 4B show a second embodiment of a device 20 according to the invention.
  • a radar or lidar sensor 21 is provided on either side of the danger zone D.
  • the sensor 21 provides a 3D shaped monitoring area 22 with an opening angle ⁇ in the vertical plane and an opening angle ⁇ in the horizontal plane.
  • one side of the monitoring area 22 is parallel to the danger zone D, while the opposite side diverges from the danger zone D.
  • a cone shaped monitoring area 22 is provided, which allows for early detection if a person moves in the direction S towards the danger zone D. This allows for the controller to anticipate on a possible entry of the danger zone D and for stopping the lifting frames.
