Description

DESCRIPTION

Stop member to limit a tipping movement of a container during emptying of the container

The present invention relates to a loading system according to the preamble of claim 1, comprising a stop member for limiting a tilting movement experienced by a container, for example a bucket, during its emptying. Said stop member is particularly used in a collector as applied, for example, in a garbage truck in order to prevent such containers from falling into the collector. Containers or bins filled, for example, with waste such as household garbage, waste paper, green waste, etc., are normally collected with garbage trucks. In practice, such garbage trucks are usually provided with a loading system with which the containers can be lifted and emptied into the garbage truck with a tilting or rotating movement. Containers or buckets must be stopped during this movement using a stop member.

DE-C-10221 828 discloses a stop member according to the preamble of claim 1.

One problem here is that in practice several different dimensions apply for individual container or bin types. This results, among other things, in container damage when a different size container is emptied. The stops known in practice usually make use of complex systems comprising complex controllers and actuators to adapt the movement of the stop to the type of container to be emptied.

The present invention aims to provide a stop member provided with a relatively advantageous and robust mechanism in order to avoid or at least reduce the problems mentioned above. This object is achieved with a loading system according to claim 1, comprising a stop member for limiting a tilting movement of a container during emptying thereof.

By providing a boundary element, preferably in the form of a rod-shaped body, a container is stopped during the tilting movement while emptying. To this end, the boundary element is preferably moved from a rest position to the boundary position during the tilting movement. This movement makes it possible for the container to rotate with the opening side, after which the container side comes into contact with the stop member. The two movements of the container and the stop member are adapted to each other for this purpose. According to the invention, this adaptation is carried out by means of a mechanical and / or hydraulic follower mechanism to actuate the delimiting element between the rest position and the delimiting position.

An operational range around a delimiting position is provided in accordance with the invention by operatively connecting a spring element to the delimiting element. This makes it possible for a container that is being emptied and having different dimensions to come into contact with the stop member and, as a result of the operating range, to remain free from damage while the contents of the container are being removed. This is done because the larger dimensions of a container usually also mean a greater weight, so that the spring element is compressed, lengthened and / or twisted depending on the position of this spring element, and therefore allows the longest possible career. A smaller size container is usually lighter in weight and therefore you will need to make less use of the operating range.

The trigger mechanism is activated directly by tilting movement so that in the bounding position the bounding element comes into contact with the container. This is achieved by mutually connecting the trigger mechanism and the tilt mechanism through a direct connection to make the desired adjustment. A mechanical actuation mechanism according to the invention is realized by direct coupling between the tilt mechanism of the container and the actuation mechanism of the stop member. This direct coupling can take place, for example, by means of a shaft connection, a hinge connection, a cam follower system, as well as by means of a hydraulic connection using, for example, two cylinders. Other mechanisms according to the invention are also possible. Also included here are embodiments that make use of a chain, rope or belt. A purely mechanical connection, such as a cam follower system, is shown in the embodiments, as maintenance and malfunction are therefore limited.

Examples of different types of containers found in practice are EN 840-1, -2, -3 and -4. Other types of buckets or containers can also be emptied using the stop member according to the invention.

A robust and reliable system is obtained to limit the tilting movement of the container or bucket to be emptied by using the boundary element in combination with the spring element and the activation mechanism. It has also been found that the maintenance required and the failures that occur are further minimized compared to the relatively complex systems known in practice. This complexity is due, for For example, to the application of a range of sensors that require additional components, control and maintenance. Furthermore, it is also possible to dispense with time delays and / or time switches as applied in such complex systems known in practice.

In an advantageous preferred embodiment according to the present invention, the direct connection between the tilt mechanism and the activation mechanism adapts the movements of these respective mechanisms to each other immediately after emptying the container.

Adapting the movements that follow the emptying of the container or bucket prevents the stop member and the container from coming into contact with each other while being deposited and damage, for example, to a container lid.

In an advantageous preferred embodiment according to the present invention, the stop member comprises a locking means for locking the stop member.

The stop member can be fixed, particularly in the rest position, by providing a locking means. This achieves an additional means of security if a container or bucket presses through the operating range or range of motion, for example in the case of large containers. It is also possible to empty containers, or to place objects in a collector or garbage truck, without making use of the stop member. This increases the flexibility of the entire stop member.

Preferably, the locking means is operatively connected to a release element. Operation of this release element releases the locking means and leaves the bounding element free for use during a subsequent emptying of a container. The container here preferably activates the release element during the tilting movement of the next container. This achieves a very advantageous operation, where it is possible to dispense with complicated controls.

The invention further relates to a collector provided with a charging system as described above. Said collector provides the same effects and advantages as those established for the charging system. In an advantageous embodiment, the manifold comprises a second stop member as described above, and the manifold is here rotated from a control element for synchronous or independent control of the two stop members. Preferably, the control element can allow synchronous or separate operation of the two stop members as desired. This can be applied advantageously in, for example, garbage trucks provided with two tilting mechanisms, so that the relatively small containers or buckets can be emptied independently of each other and the large containers or buckets can be emptied together in synchronous operation with the two. systems.

The invention also further relates to a garbage truck provided with a collector as described above. A garbage truck of this type provides the same effects and benefits as those indicated for the loading system or the collector.

The invention also relates to a method for limiting a tilting movement of a container during its emptying into a collector, comprising providing a loading or collector system as described above.

Such a method provides the same effects and advantages as those established for the loading system, collector and / or garbage truck.

Other advantages, characteristics and details of the invention are explained on the basis of preferred embodiments thereof, where reference is made to the accompanying drawings, in which:

- Figure 1 shows a view of a collector according to the invention for a garbage truck provided with the stop element;

Figure 2 shows a view of the stop member of figure 1;

Figures 3-5 show views of the different stages of the tilting moment with the stop member of Figure 1; Y

- Figure 6 shows a view of the emptying of a large container with a double stop member.

A garbage truck 2 (figure 1) is provided with a loading system 4 with which the containers 6 provided with a lid 8 can be lifted from a ground surface 10 using the lifting mechanism 12, and particularly the teeth 14 of the itself, so that the content can be emptied. in the collecting space 16. The Loading system 4 is here provided with a stop member comprising a stop bar 18. The stop bar 18 is attached to the arm 20 and fixed to the loading system 4 by the partitions 22, 24. The follower mechanism 26 provides the movement of the stop bar 18 during the tilting of the container 6 using the lifting mechanism 12 In the embodiment shown, two lifting mechanisms 12 are provided adjacent to each other. Thus, an independent operation can be applied in order to empty two containers 6 independently of each other and / or a synchronous operation can be applied in order to empty a single large container that is collected and deposited by the two mechanisms of elevation 12.

The container 6 is picked up from the ground surface 10 using the lifting mechanism 12. During this movement, the container 6 is brought from a vertical position through a substantially horizontal position (Figure 2) to an emptying position (Figures 3 and 4, with figure 4 being a view from the garbage truck 2). In the emptying position, this container 6 is brought into a position such that the lid 6 is opened or, in an alternative embodiment, it is guided by additional guides, and the contents of the container 6 are brought into the collecting space 16. The container 6 It rests here on the support block 28. The container 6 is limited in the emptying position by the stop bar 18 which ensures that the container 6 does not fall into the collection space 16.

Follower mechanism 26 (Figures 5 and 6) is provided with a cam 30 with which a cam follower 32 is in contact during use. A first outer end of cam follower 32 follows this cam 30. The other outer end of cam follower 32 is connected to guide 34 using a fastener or profile 36. In the embodiment shown, an arm 38 is provided thereon. outer end. The arm 38 is further provided with a recess 39 for guiding purposes. Located at the outer end of arm 38 is shaft 40 running through partitions 22, 24. In the embodiment shown, a spring element 42 is disposed between partitions 22, 24. Cam 30 rotates through connection 44 with which the follower mechanism 26 is in direct mechanical connection with the lift mechanism 12.

A fixing element 46 is also provided, on which shaft 40 can be fixed using tab 48. Release element 50, for example, in the form of a latch, removes tab 48 so that shaft 40 can re-engage. released and stop bar 18 is functional again. In the embodiment shown, the spring element 42 is realized as a first flange 52 provided on the side of the stop bar 18, a second flange 54 provided on the side of the arm 38 and a spring block 56 provided between the flanges 52 , 54. It will be apparent that other embodiments of the spring element 42 are also possible.

When a container 6 has to be emptied, it is picked up from the ground surface 10 using the lifting mechanism 12. During the lifting movement (Figures 1-4) the container 6 undergoes a pivoting or tilting movement. To prevent container 6 from falling into collecting space 16, a stop bar 18 is placed to stop container 6. According to the invention, follower mechanism 26 is directly connected to lifting mechanism 12 using direct mechanical connection 44 of so that the movement of the stop bar 18 adapts to the pivoting movement of the container 6. In this way a robust and reliable mechanical system is realized. Additional maintenance time and / or complex components, including control, are no longer necessary here. According to the invention, the stop bar 18 is connected to a spring element 42 such that some operating range results and the stop bar 18 may undergo a small change in position, for example as a result of weight and / or or dimensions of container 6, without follower mechanism 26 is affected. This prevents damage to a container 6 of a slightly different size being emptied. Once the container 6 has been emptied, it is re-deposited on the floor surface 10, in which a reverse movement is followed. The follower mechanism 26 here provides a return movement of the stop bar 18 which also adapts to the movement of the container 6.

In an alternative embodiment, the follower mechanism 26 takes a hydraulic form. In this case, two hydraulic cylinders are operatively connected to each other. These cylinders transmit the movement of the container 6 during the tilting movement through a first cylinder to a second cylinder and, therefore, to the stop bar 18. As a result, the stop bar 18 undergoes a movement adapted to the movement container tilt 6. Reverse movement occurs during descent.

The present invention is in no way limited to the above-described preferred embodiments thereof. The rights sought are defined by the following claims, within the scope of which many modifications can be envisaged. Thus, it is possible, for example, to incorporate the spring element 42 as a kind of flexible sleeve around the stop bar 18. Other embodiments are also possible.
