This allows the most uniform possible filling of the container under the distribution chute.

In addition, it is known from the prior art, in coming out of a production machine piece goods that must be filled into containers, container by means of appropriate mechanisms of the bulk material transfer position of the conveyor to and remove there. This can be z. B. via appropriately changing devices that allow to supply empty containers and remove filled containers and then pass them to another location to appropriate transport vehicles.

Object of the invention

Based on this prior art, the present invention has for its object to provide a compact filling and changing device that allows optimal filling with an optimal replacement of empty and full containers.

This object is achieved by a filling and changing device with the features of claim 1.

The receiving area receiving the at least one container to be filled is designed so that it can be moved horizontally both horizontally relative to the bulk material transfer position and also vertically. The vertical movement effected by means of a lifting device permits vertical movement of the container on the one hand when filling with bulk material, but on the other hand also for transferring the receiving region to container transfer positions in which empty and full containers are exchanged. Since all this can be done with a lifting device, this results in a space-saving compact design that meets the requirements of practice.

Basically, the filling and changing device is equipped with a lifting device which is formed by a lifting column, in which a receiving area forming carriage is provided. In addition, a further height adjustment device can be provided, with which the bulk material transfer position is also equipped with adjustable height. As a result, the container and the bulk material transfer position can be adjusted relative to one another and, above all, independently of one another. Thus, the filling and changing device can be taken into account in each case existing requirements when feeding the bulk material from the manufacturing machine to the container. The filling and changing device is so versatile adaptable to different transfer heights of the bulk material from the conveyor to the filling device. In the area of the bulk material transfer position, a chute can be provided for the time in which a replacement of a filled container by an empty container takes place, which can be transferred to a rest position during these times.

To the filling and changing device, a storage system can be coupled, can be stored on the several filled containers as well as several empty containers. Preferably, height-spaced container transfer positions are provided, once for feeding empty containers and once for discharging filled containers. By provided on the filling and changing device lifting the respective container transfer positions can be controlled easily.

The lifting device thus has several tasks that can be tracked independently. In combination with the also height-adjustable chute is thus a versatile adaptation of the device to the local conditions and high flexibility to adapt to changing conditions possible.
