Description

Safety barrier

Technical field

The invention relates to a safety bolt of an emptying device for emptying garbage containers into a collecting bin. a container, with at least one first and one second part, at least the first part of the bolt being movable to a rest and locking position.

BACKGROUND OF THE INVENTION

DE-PS 34 05 997 discloses a vessel emptying device in which the working area in the vicinity of the tilting device or the lifting and tilting device is provided by means of barriers acting blocking the control circuit. These obstacles are mounted to be rotatable about a horizontal axis on the side walls of the garbage vehicle or on a respective device for the protection of operating personnel and unauthorized persons, for example bystanders. These include, for example, the barriers which are in the rest position · ». rotated upwards and downwards in the operating position and then occupy a substantially horizontal position. In working position

- these barriers are actuated by a switching element which closes the current control circuit for actuating the discharge device. In the rest position of this obstacle, this switch is released, thereby breaking the current control circuit. It has been shown that these barriers can be handled, so that the discharge device operates even after the barriers have not taken up their locking position.

EP-A-0 278 307 discloses a securing device for a lifting and tilting or tilting device, in which the receiving opening of the collecting container is provided with an orifice which surrounds the working area of the lifting and tilting or tilting device as a hatch. This screen is made up of a plurality of wall parts connected by guide rails movable with the collection container. An electric switch is also provided in this orifice, arranged in the current control circuit for controlling the discharge device, and which is only switched on in the closed operating position of the orifice. It is also possible in this curtain that the switch can be manipulated so that the protection of the working area of the lifting and tilting device by means of a hatch need not be removed at all to be able to operate the lifting and tilting device.

In order to prevent the evacuation emptying device from being prevented from being bypassed, a lateral aperture of the device has already been developed which carries the operating elements of the device. The operating elements are covered by the movable part of the bolt after the part has taken a rest position. In order to access the operating elements of the emptying device, this barrier part must swing down to the locking position. However, this type of security barrier has the disadvantage that the movable barrier part can be removed without affecting the emptying device or its operation. When this movable barrier part is removed, the operating elements are freely accessible and the discharge device can be operated without restriction.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safety barrier which allows the discharge device to be operated only in the locked position and which cannot be manipulated.

SUMMARY OF THE INVENTION

This object is achieved by a safety bolt of a discharge device for emptying garbage containers into a collection container, with at least one first and one second part, wherein at least a first bolt part is movable to a rest and locking position according to the invention. extends into the collecting container at least so far that the working area of the emptying device is laterally secured that all the operating elements of the emptying device are located on the first movable barrier part and that the first movable barrier part cooperates with the second barrier part so that the operating elements of the emptying device are inaccessible in the rest position of the first movable part of the barrier.

In known emptying devices, the operating elements of the emptying device are generally located on the emptying device directly or on a collection container. The safety devices, such as various barriers and the like, which are provided in this case, are spatially separated from the operating elements, so that the dismantling of the safety barriers or the handling of their respective switches has no effect on the operation of the discharge device.

The invention is based on the finding that manipulation is no longer possible even after all the operating elements of the emptying device are located on the movable bolt part which secures the working area of the emptying device laterally, the first movable bolt part cooperating with the second bolt part so that the operating elements the discharge device is inaccessible in the rest position of the first movable barrier part. This means that the operator must first move the first movable bolt part to the locking position in order to operate the discharge device. Working area means the area behind the collecting container that is required for the emptying device with the garbage container gripped during the emptying process.

Removing this first movable barrier part would also result in removal of the operating elements of the discharge device. Fixing to the barrier part by placing it closer to the collection container would not achieve the desired success, since then the barrier parts could be dismantled without affecting the discharge operation. wherein the working area of the discharge device would no longer be fully secured.

In addition to the first and second panels, the security bolt may have other panels which may be arranged, for example, between the first and second panels, between the second panel and the collecting container, or at the free end of the first panel.

In order to prevent the operating elements from being accessible in the rest position, which would otherwise cause the operator to keep the movable bolt part in the rest position, the second bolt part is designed to completely cover the operating elements in the rest position of the first movable bolt part.

Advantageously, the operating elements are arranged at the free end of the first movable bolt part so that, especially when emptying large garbage containers, the operator can push the container to be received and at the same time reach the operating elements.

The operating elements can also be arranged at a supported end of the first movable barrier part, which has the advantage that the operating elements are completely and unobstructed accessible only in the locking position of the moving barrier part. In this case, the operator is preferably completely outside the working area of the discharge device.

Another possibility is that the operating elements are arranged on the outside of the first movable part of the bolt. The second bolt part is then formed such that the first movable bolt part in the rest position is mounted therein at least so far that the operating elements are not accessible.

Between the rest position and the securing position, the moving part of the barrier must travel a certain distance. It is possible that the operator only pulls the movable bolt part out of the rest position so that the operating elements are at least partially accessible. In this case, however, the barrier cannot fully develop its action. In order to prevent this, at least one concealed switching element is provided according to a further embodiment of the invention, which is movable from the rest position to the locking position and inversely actuated when the first movable barrier part is moved. Preferably, the switching element is arranged inside one of the two bolts so that it is then not accessible from the outside and cannot be operated by the operating personnel. The switching element is arranged in such a way that it is only accessible after the movable barrier part has been removed.

Preferably, the switching element is designed to interrupt the power supply to the service elements in the rest position of the movable bolt piece, the power supply to the service elements being provided only when the first movable bolt portion is in the locked position. A further possibility is that the switching element emits a signal according to the position of the movable barrier part on the control device of the discharge device. In this example, the operating elements are non-functional in all positions of the movable barrier part - except for the locking position.

The safety bar can be designed in various ways. In one embodiment, the first bolt part is arranged directly on the discharge device or on a collection container. The second part of the bolt, which is to obstruct and prevent access to the operating elements in the rest position, is an integral part of the discharge device or the collecting container. For this purpose, it is sufficient, for example, to provide, on the collecting container, a part provided with a recess in which the operating elements ú

interfere when the movable first bar part moves to the rest position.

According to a further embodiment of the invention, a separate second bolt part is fastened to the discharge device or to the collection container, and the second bolt part carries the first bolt part. The second barrier part can be fixed or movable. Depending on the design of the emptying device or the collecting container, it is also possible to provide two or more bolt parts between the movable part of the bolt and the emptying load, or the collecting container. However, it is preferred that the second bolt part is mounted on the discharge device or on the collection container.

In an embodiment with a fixed second bolt piece arranged, the movable bolt piece is preferably rotatable about a horizontal axis on the second bolt piece. The front side of the second bolt piece is then configured to receive the service elements in the rest position of the movable bolt piece. The moving part of the barrier can also be rotatable about a vertical axis.

According to a further embodiment of the invention, the second bolt part is provided with a cover into which the first movable bolt LX1 is inserted into the rest position. Preferably, the cover is formed of a tube arranged substantially in the horizontal direction into which the movable bolt piece can be inserted. The cover is designed in such a way that, depending on the arrangement of the operating elements on the movable part of the bolt, the operating elements are inaccessible at least in the rest position.

Preferably, the second bolt is formed such that all points of the discharge device at which shearing or shear injuries can occur and which are laterally accessible substantially at the height of the operator's arms are covered. The second bolt is formed as a side cover of the emptying device in the form of a plate, so that lateral interference with the emptying device is virtually impossible.

According to a further embodiment of the invention, the second part of the bolt is designed as double-walled and at least partially formed as a cable guide. Since in the area of the discharge device, lines and cables are required for the control and operation of the servomotors, which are laid on the outside in the prior art solution and can therefore be damaged, there is now the possibility of placing these components protected.

In order to further protect the lateral part of the discharge device, a canvas may be arranged between the first movable barrier part and the second barrier part, which is tensioned in the securing position of the first movable barrier part.
