Abstract
A packaging machine and method for filling bags with a supporting structure to which at least one filling box is fastened which includes a conveyor element and to which a weighing device and a filling spout are assigned. A control device is provided. The filling box is retained non-communicating with the supporting structure and the assigned filling box and is weighed separately by the assigned weighing device to discharge from the filling box a predefined quantity of intended fill product by way of differential weighing and to fill it into the bag through the filling spout. The control device controls the strength of a volume flow into the bag over the time of the filling process so that the intended fill product is maintained at a high fill height while overflow is simultaneously prevented.
Claims12
A packaging machine for filling bags comprising:
- a supporting structure;
- at least one filling box fastened to said supporting structure, said at least one filling box comprises at least one conveyor element and a silo, said silo configured to store an intended fill product and includes at least one of a controllable dosing element and a closing head;
- a weighing device and a filling spout assigned to said at least one filling box, wherein said filling spout is fastened to the supporting structure and is elastically connected with said at least one filling box;
- at least one control device associated with said at least one filling box;
- the filling box is retained non-communicating with the supporting structure and the assigned filling spout and the intended fill product is weighed separately by the assigned weighing device to discharge from the filling box a predefined quantity of the intended fill product by way of differential weighing and to fill the intended fill product through the filling spout into the bag;
- and
- the control device is configured for controlling the strength of the volume flow into the bag over the time of the filling process so that the intended fill product is maintained at a high fill height during the filling process while overflow is simultaneously prevented.
A method for filling bags by means of a packaging machine, comprising:
- providing a supporting structure and at least one filling box, wherein said at least one filling box is fastened to said supporting structure and comprises a conveyor element;
- providing a weighing device and a filling spout each assigned to said at least one filling box, wherein said filling spout is fastened to the supporting structure and is elastically connected with the at least one filling box;
- holding the filling box non-communicating with the supporting structure and the assigned filling spout;
- separately weighing an intended fill product by the assigned weighing device to extract from the filling box a predefined quantity of the intended fill product by way of differential weighing, controlled by a control device;
- and
- filling the intended fill product through the filling spout into the bag,
- wherein during the filling process, a strength of the volume flow is timed by means of the control device in dependence on the filling duration so that a fill height of the intended fill product is maintained high during the filling process while simultaneously preventing overflow.
