Definitions

  • the invention relates to a loading device for a refuse collection device according to the preamble of claim 1.
  • a loading device of this nature is known (see for example EP-A- 671346).
  • the control means of the known loading device are designed such that, in the event of certain predefined unsafe states of the loading device occurring, an automatic loading cycle of the loading device cannot start or cannot continue. In the latter case, the loading cycle is interrupted when the pick-up member is already at a certain height. This has the drawback that a filled container of considerable weight (max. approx. 100 kg) has to be lowered in an unsafe situation. Moreover, the undesirable movements of the loading device waste time.
  • the object of the invention is to eliminate the abovementioned drawbacks and to provide a loading device which is simpler and safer.
  • the pick-up part of a container cannot be placed over the pick-up member in the event of the relevant unsafe states occurring.
  • the pick-up device is then unable to pick up a container, and the loading device is practically unusable. This prevents a container from being picked up in an unsafe situation and being lifted to a certain height, from which it then has to be lowered again.
  • the loading device which is diagrammatically depicted in Figs. 1 and 2 and is provided in duplicate is intended to form part of a refuse collection device, such as a refuse collection vehicle.
  • a loading device may in practice be designed in a large number of different ways which are known to the person skilled in the art.
  • the loading device comprises a pick-up device 1 and lifting arms 2, which are supported by a supporting part 3 (indicated diagrammatically here) of the refuse collection device.
  • This part 3 is, for example, the loading container of a refuse collection vehicle.
  • the pick-up device 1 is designed to pick up containers, in particular refuse containers, which are provided with a pick-up part which is open downwards, in the form of a top edge 4 which is bent over outwards and downwards in the form of a U.
  • the pick-up device 1 is provided with a pick-up member 5 which can engage beneath the U-shaped top edge 4 of a container which is to be picked up.
  • the pick-up member 5 comprises a pick-up plate with pick-up teeth 6.
  • the pick-up member may also be of different design, for example in the form of a strip.
  • the pick-up member may also be designed in such a manner that it is suitable for picking up containers with a round top edge or containers with a so-called delta-shaped pick-up part. In the latter case, the pick-up member is designed as a so-called "delta pick-up".
  • the pick-up device furthermore comprises an edge-locking member 7 which is arranged in the vicinity of the pick-up member 5 and, by means of actuating means (not shown in Fig. 1), can be moved between a locking position (shown in solid lines) and a non-locking position (shown in dashed lines).
  • the edge-locking member 7 In the locking position, the edge-locking member 7 is situated at least partly at a certain distance above the pick-up member 5, in such a manner that when the pick-up member 5 engages beneath the top edge 4 of a container, the edge-locking member 7 holds the U-shaped top edge 4 of the container securely on the pick-up member 5.
  • the edge-locking member 7 is situated next to the pick-up member 5, in such a manner that the U-shaped top edge 4 of a container can be positioned over the pick-up member 5.
  • Fig. 3 diagrammatically depicts a slightly different design of pick-up member 5 with edge-locking member 7.
  • the edge-locking member 7 is provided with actuating means in order to move the edge-locking member 7 out of the non-locking position into the locking position.
  • the actuating means comprise a pneumatic bellows 11 with an air line 12 which is connected thereto and in which a two-way valve 13 is accommodated and which is connected to a compressed-air source 14.
  • the two-way valve 13 is electromagnetically actuated (coil 15).
  • coil 15 When the coil 15 is energised, a spring 16 presses the valve 13 into the position illustrated in Fig. 3, in which the bellows 11 is under pressure and the edge-locking member is in the locking position.
  • the actuating means may also be differently designed, for example may be of hydraulic or magnetic design.
  • the loading device furthermore comprises control means for the automatic control of the loading device, the actuating means of the edge-locking member 7 being coupled to the control means.
  • the control means of the loading device are designed in such a manner that, in the event of certain predefined unsafe states of the loading device occurring, the edge-locking member 7 is moved into the locking position by the control means and the actuating means.
  • the edge-locking member 7 shields the pick-up member 5, so that a U-shaped top edge 4 of a container can no longer be placed onto the pick-up member 5.
  • the edge-locking member 7 functions as a safety member.
  • the loading device can move, it is not possible for a container to be picked up, so that the loading device is practically unusable.
  • the top side 17 of the edge-locking member 7 is preferably bevelled, making it impossible to attach a top edge 4 of a container to the edge-locking member 7.
  • the loading device may be provided with a separate safety member arranged in the vicinity of the pick-up member 5.
  • This safety member should then be moveable between an active position, in which it prevents the pick-up member 5 from being able to engage beneath the pick-up part (the top edge 4) of a container, and an inactive position, in which the pick-up member can engage beneath the pick-up part (the top edge 4) of a container.
  • a safety member of this nature is then coupled to the control means in such a manner that, when an unsafe state is signalled, the safety member is moved into the active position.
  • An unsafe state may occur if a monitoring member 8 (illustrated diagrammatically in Fig. 2), which is arranged in the vicinity of the pick-up member and is coupled to the control means, for monitoring the presence of a U-shaped top edge 4 of a container on the pick-up member 5, indicates the presence of a U-shaped top edge on the pick-up member after a loading cycle of the loading device has ended, in an operating position of the pick-up device 1 which is so low that it is impossible for there to be a U-shaped top edge 4 on the pick-up member 5.
  • a monitoring member 8 illustrated diagrammatically in Fig. 2
  • the monitoring member 8 may be designed in various ways.
  • the monitoring member 8 may comprise two start switches which are arranged next to and at a distance from one another and can be actuated by the front wall of a container which is to be picked up when this container is placed against the pick-up member 5 in order to start a load cycle.
  • the monitoring member 8 may also comprise an element (chip-reader) of a container-recognition system or a monitoring switch which can be actuated by the U-shaped top edge 4 of a container which has been picked up by the pick-up member 5.
  • An unsafe state may also occur with regard to shielding elements which are arranged on either side of the loading device, for shielding the movement area of the loading device at the side.
  • Fig. 4 diagrammatically depicts a shielding element 21 for shielding the movement area of a loading device of a refuse collection device.
  • a loading device would be mounted at the rear or on the side of a refuse collection vehicle.
  • the shielding elements are used to shield the movement area of the loading device from the side during operation, in order to prevent people from inadvertently coming into the movement area of the loading device from the side, which could cause unsafe situations.
  • the shielding element 21 comprises a bracket 22 which is pivotably connected to the device for emptying refuse containers by means of a pivot 23 with a horizontal pivot axis.
  • Fig. 4 shows the shielding element 21 in the shielding position. In the non-shielding position, the shielding element 21 is in a position in which it has been rotated through approx. 90° in the direction of arrow 24 with respect to the shielding position illustrated in Fig. 4.
  • the shielding element in accordance with Fig. 4 is provided with a panel 25 which is provided with actuating buttons for actuating the loading device.
  • Signalling means for signalling the position of the shielding element are arranged in the vicinity of the pivot 23 of the shielding element 21. These signalling means are shown in more detail in Figs. 5 and 6.
  • a pivot bush 27, which is fixedly connected to the bracket 22, of the pivot 23 is provided with a recess 28.
  • the pivot bush 27 can rotate about a pivot pin 29 which is connected to the refuse collection device.
  • a sensor 30 which signals whether the shielding element 21 is in the shielding position (Fig. 5) or in the non-shielding position (Fig. 6).
  • the recess 28 in the pivot bush 27 is at an angular distance of approx. 90° from the sensor 30.
  • the recess 28 is positioned directly opposite the sensor 30.
  • the sensor 30 emits a different signal in each of these two situations.
  • the shielding element can also be of different design, and the position of the shielding element could be signalled in a different way, for example in the way described and illustrated in EP-A-0671346 in the name of the applicant.
  • the shielding elements 21 and the edge-locking member 7 are coupled to one another in such a manner, in this case via signalling means (sensor 30), the control means and the actuating means 11-16 of the edge-locking member 7, that when one or both of the shielding elements 21 is/are in the non-shielding position (Fig. 6), the edge-locking member 7 is in the locking position.
  • a manually actuable shield-locking member is arranged at each shielding element 21, which shield-locking member can be moved between a non-locking position and a locking position, in which the shield-locking member locks the shielding element 21 in the shielding position.
  • the shield-locking member which is denoted by 32, is designed as a lever 34 which can rotate about a pivot point 33 and is provided, on its top side, with a knob 35 for manual actuation.
  • the lever 34 is furthermore provided with a projection 36 which can latch into the recess 28 in the pivot bush 27 of the pivot 23 of the shielding element 21 when the shielding element 21 is in the shielding position (Fig. 5), in order to block a rotational movement of the shielding element 21.
  • the lever 34 is connected to a spring 37 (in this case a tension spring), which forces the shield-locking member 32 into the locking position.
  • the spring 37 is pulling the projection 36 into the recess 28 in the pivot bush 27.
  • the shield-locking member 32 has to be moved manually, and counter to the force of the spring 37, into the position illustrated in Fig. 6 (non-locking position). Only then can the shielding element be moved into the non-locking position (Fig. 6).
  • a second sensor 38 which signals whether the lever 34, and therefore the shield-locking member 32, is in the locking position (Fig. 5) or the non-locking position (Fig. 6).
  • the sensor 38 is the same type of sensor as the sensor 30.
  • This sensor 38 is also coupled to the actuating means of the edge-locking member 7 via the control means, in such a manner that when the sensor 38 signals that the shield-locking member 32 is in the non-locking position (Fig. 6), the edge-locking member 7 moves into the locking position (Figs. 1 and 3).
  • control unit of the loading device is designed in such a manner that if, during a normally proceeding movement cycle for emptying a container which has been picked up by the loading device, a shielding element is moved into the non-shielding position, this cycle of the loading device is brought to an end.
  • the edge-locking member 7 will at some time move into the non-locking position, in order to allow the container to be removed from the pick-up member 5, but in the at-rest position, in which it is no longer possible for a container to be picked up, will move into the locking position in order to be able to exercise the safety function.
  • the lever 34 of the shield-locking member 32 may furthermore be coupled to the piston rod 42 of a single-acting cylinder 41 which, when the loading device is active, is activated and holds the shield-locking member 32 in the locking position (Fig. 5) and is not activated only when the loading device is in the at-rest position.
  • the shield-locking member can only be moved manually out of the locking position in the situation in which the loading device is in the at-rest position.
  • a single-acting blocking member which comprises, for example, a single-acting cylinder acting directly on a shielding element 21, in parallel with the shield-locking member 32.
  • a blocking member of this nature could be provided with a projection which is able to latch into a recess in the pivot bush 27, such as the projection 36 which is able to latch into the recess 28, and in this way blocks the shielding element 21 in the shielding position.
  • the measures described above provide an optimum level of safety.
  • the shielding elements 21 can only be moved into the non-shielding position when the loading device is entirely inactive and is in the at-rest position. In order to be able to use the loading device, i.e. in order to be able to pick up and empty containers, it is necessary to move the shielding elements 21 into the shielding position, in order to move the edge-locking member 7 into the non-locking position, so that a container can be picked up. Once this has taken place, the shielding elements may only be moved back into the non-shielding position when the loading device is deactivated.
  • the action of the sensors 30 and 38 is monitored by the control means.
  • the loading device When the loading device is started up, it is firstly necessary to change the state of the sensors (30 and 38) by moving the shielding elements into the shielding position.
  • the control means then monitor the action of the sensors 30 and 38, and the loading device is enabled if they function correctly.
  • a further safety measure which can be incorporated is that when the shielding elements 21 move out of the non-shielding position into the shielding position, the edge-locking member 7 does not move directly into the non-locking position, but rather waits for the actuation of a button (for example the "down" button of the loading device).
