Definitions

  • the invention relates to a device for emptying refuse bins in a collecting container, whereby at least one loading device is provided for picking up a refuse bin and whereby a safety arm is provided at at least one side of the loading device, the safety arm being moveable between an active position and a rest position, whereby in the active position the safety arm laterally shields the movement area of the loading device, and whereby in the rest position the safety arm does not shield the movement area.
  • the invention will primarily be applied with refuse collecting vehicles, where refuse bins are emptied in a collecting container.
  • the movement area of an automatic or semi-automatic loading device must be shielded laterally against inadvertent persons, so that these persons can not be present within the movement area of the loading device during the loading operation and thereby be jammed under the refuse bins.
  • Rigid (permanent) safety arms, moveable safety arms as well as contactless detection elements are used to fulfil these safety requirements.
  • the complete safety device must ensure that the automatic or semi-automatic loading device can not be used when the safety arms are located in the non-shielding position (rest position).
  • the European Patent application EP0156445 (Zoller-Kipper) describes different embodiments of such a refuse collecting vehicle provided with moveable safety arms.
  • the safety arm is pivotally connected adjacent to the loading device and can be unfolded downwardly from its upper rest position to its backwardly extended active position. In the active position the safety arm activates a switch which allows the automatic or semi-automatic use of the loading device. When the safety arm is raised and the switch is de-activated, the switch is blocking the control circuit of the loading device, so that an automatic or semi-automatic operation becomes impossible.
  • the safety arm is pivotally connected adjacent to the loading device and can be unfolded downwardly from its upper rest position to its backwardly extended active position. In the non-active position the safety arm actuates a switch which controls a locking member adjacent to the pick-up member of the loading device whereby this locking member prevents that refuse bins can be picked up by the pick-up member. In order to operate with the loading device the safety arms must be brought in their shielding position.
  • the purpose of the invention is to provide a loading device which eliminates the drawbacks of the known devices.
  • a device for emptying refuse bins in a collecting container whereby at least one loading device is provided for picking up a refuse bin and whereby a safety arm is provided at at least one side of the loading device, the safety arm being moveable between an active position and a rest position, whereby in the active position the safety arm laterally shields the movement area of the loading device, and whereby in the rest position the safety arm does not shield the movement area, whereby the safety arm comprises a part which is pivotable around a horizontal axis, whereby in the rest position said part is located on or within the path of the operating loading device, and whereby in the active position said part is located outside the path of the operating loading device, such that, when the safety arm is in the rest position it will be forced towards the shielding active position by the operation of the loading device.
  • the safety arms are located in a vertical position, pivoting around a horizontal axis, such that in the rest position the safety arms are located at the sides of the refuse collecting vehicle.
  • the advantage of the vertically located safety arms is that they do not cause any inconveniences when the refuse collecting vehicle is used without the loading device.
  • the refuse collecting vehicle remains multi functional for the collection of gross garbage, refuse bags etc.
  • the loading device can be built with a greater width, such that wider and larger refuse pieces can be collected in the refuse collecting vehicle.
  • the location on the safety arms of the control buttons of the loading device and/or the compacting device has the advantage that due to the vertical rest position of the safety arms said buttons cannot be damaged when refuse bags or gross garbage are thrown in the collecting container; throwing in of the refuse is not troubled either by the position of the control buttons.
  • a guide plate such that the movement of the guide plate from the downwardly collapsed rest position towards an upwardly extended position will force the safety arm from its rest position towards its shielding active position.
  • a guide plate whereby the control buttons of the guide plate are located on the safety arm.
  • the advantage hereof is that in the first place the operator will manually bring the safety arm to its shielding active position, before bringing the guide plate to the upwardly extended position. This prevents that the loading device forces the safety arm unexpectedly towards its shielding active position.
  • a spring actuates the safety arm such that the spring can force the safety arm towards its shielding active position.
  • the advantage hereof is that the movement of the safety arm towards its shielding active position occurs gradually and that it ensures also that the safety arm is brought to the shielding active position. Moreover the movement of the guide plate occurs more smoothly than the movement of the loading device. Hereby the movement of the safety arms towards their shielding active position also occurs more smoothly.
  • the loading device comprises a start button which initiates an automatic loading cycle and in that the downwardly collapsed guide plate at least partially shields the non-operating loading device, so that said start button becomes inaccessible.
  • the advantage hereof is that the loading device cannot be operated automatically when the guide plate is not in its upwardly extended position, because the start button (which initiates the loading device) is inaccessible.
  • the safety arms will be forced towards their shielding active position.
  • the safety arm is provided with sensors which can detect the position of the safety arm, such that a warning signal is generated when the safety arm is still in the rest position and the loading device is raised.
  • the advantage hereof is that the operator is warned about the automatic lowering of the safety arms towards their shielding active position.
  • the safety arm is provided with sensors which can detect the position of the safety arm, such that the upward movement of the loading device will be blocked when the safety arm is still in the rest position.
  • the advantage hereof is that the mechanical safety device according to the invention is completed by an electronic safety device.
  • the unexpected and forced movement of the safety arms towards their shielding position is prevented.
  • Sabotage of the sensors will not lead to the non-fulfilment of the safety norms, because the mechanical safety device will continue to fulfil the norms.
  • a double safety system there is provided a double safety system.
  • safety arms as described here above are provided both at the left side and at the right side of the loading device, whereby both safety arms are connected with each other.
  • the advantage hereof is that when one safety arm is manually moved to its active shielding position, the other safety arm will automatically follow and will also move to its active shielding position.
  • the loading device is provided with means to identify the refuse bins and with means to weigh the contents of the refuse bins.
  • FIG. 1 The figures show only the rear part of a refuse collecting vehicle (type rear-loader) according to the invention.
  • the figures 1,2 and 3 show a refuse collecting vehicle (1) suitable for the transport of refuse, whereby the refuse collecting vehicle (1) is provided with a hopper (2) which is accessible via a loading opening (3).
  • the loading device (4) comprises a hydraulic lift cylinder (5) and a pick-up device (7) supported by a rod mechanism, whereby the pick-up device (7) can be hooked behind the edge of a refuse bin to be emptied.
  • the loading device (4) is provided with a safety arm (8a, 8b) both at the left and at the right side; these safety arms (8a, 8b) shield laterally the movement area of the loading device (4) against inadvertent persons, so that these persons can not be present within the movement area of the loading device during the loading operation.
  • Each safety arm (8a, 8b) consists of a beam (9) which is pivotally connected to a fixed beam (11) by means of a pivot (10) having a horizontal pivotal axis; the fixed beam (11) is fixed to the refuse collecting vehicle (1).
  • the safety arms (8a, 8b) can be moved between a rest position and a shielding active position.
  • the shielding active position is the position wherein the safety arms (8a, 8b) shield laterally the movement area of the loading device (4).
  • the safety arms are then located outside the path (A) of the main arm (6) of the operating loading device (4).
  • the rest position is the position wherein the movement area of the loading device (4) is not shielded and wherein the safety arms (8a, 8b) are located within the path (A) of the main arm (6) of the operating loading device (4).
  • the safety arms (8a, 8b) are provided with a panel (12) which comprises control buttons (13) for the operation of the loading device (4).
  • the operator is expected to move the safety arms (8a, 8b) manually towards the active shielding position.
  • the loading device (4) can operate automatically or semi-automatically whereby the movement area of the loading device (4) is not shielded laterally by the safety arms (8a, 8b).
  • the refuse collecting vehicle (1) comprises a safety arm (8a, 8b) at the left and at the right side of the loading device (4) whereby the safety arms (8a, 8b) are interacting with the position of the guide plate (14); the guide plate (14) ensures the minimum distance (as prescribed by the norms) towards the press, which compresses the refuse in the collecting refuse vehicle, and also guides the refuse from the refuse bin to the hopper (2).
  • the guide plate (14) is collapsed downwardly so that a freely accessible loading opening (3) is created.
  • the safety arms (8a, 8b) are located within the path (A) of the main arm (6) of the operating loading device and the guide plate (14) covers the loading device (4), so that it is impossible to hang up a refuse bin onto the pick-up device (7) of the loading device (4).
  • the buttons for initiating the automatic loading cycle are also located under the downwardly collapsed guide plate (14) so that these buttons cannot be actuated by a refuse bin.
  • the guide plate (14) has to be moved towards its upwardly extended position either manually or by its own lift cylinder (not shown) after actuation of the control buttons (13).
  • the upward movement of the guide plate (14) causes the safety arm (8) to move downwardly towards its shielding active position, as shown in figure 5.
  • the safety arms (8a, 8b) are then located outside the path (A) of the main arm (6) of the operating loading device (4).
  • the guide plate (14) can force the safety arms (8a,8b) into the shielding active position or otherwise after disconnection of the elements (15) a spring (16) will move the safety arm (8) towards its shielding active position.
  • a spring (16) will move the safety arm (8) towards its shielding active position.
  • the safety arms (8) are moved automatically towards the shielding active position by the upward movement of the guide plate (14).
  • control button of the guide plate is located on the safety arm. This stimulates the operator to bring the safety arm manually towards its shielding active position, before moving the guide plate towards the upwardly extended position; hereafter the start button can be actuated to initiate the automatic loading cycle. As the safety arms have already been put manually in their active shielding position, they will not unexpectedly be forced towards that position. This enhances the safe use of the loading device with its safety arms.
  • a reliable safety device for an automatic loading device of a refuse collecting vehicle is achieved by mechanical means. Additional safety can be achieved if the safety arms are provided with sensors which can detect the position of the safety arm. When the safety arms are in the rest position and the loading device is raised (either automatically, semi-automatically or manually) a warning signal can be generated. Hereby the operator is warned about the automatic downward movement of the safety arms towards the active shielding position.
  • Additional safety can also be achieved by the provision of sensors which can detect the position of the safety arm, and whereby these sensors are blocking the movement of the loading device, when the safety arms are not yet in the active shielding position.
