PACKAGING MACHINE AND METHOD

摘要

Packaging machine and method for filling dusting product such as bulk material into open-mouth bags by means of a filling process The filling process is controlled by weight by means of a control device and a weighing device. A batching element conveys product off a product supply and introduces it through a filling spout into an open-mouth bag appended for the filling process. The filling spout is connected with a collecting tank through a flow connection such that a pressure surge occurring in the filling process is utilized for transferring into the collecting tank the displacing air contained in the open-mouth bag and containing the dusting product to receive and settle the displacing air in the collecting tank and to deposit at least the dust content of the displacing air in the collecting tank as deposited product.

主权项

1. Packaging machine for filling dusting product such as bulk material into open-mouth bags by way of a filling process, having a control device and a weighing device for weight-dependent control of the filling process, and having a product supply and at least one batching element and with a filling spout through which the product can be delivered to a prepared open-mouth bag during the filling process,
characterized in that the filling spout is connected with a collecting tank through a flow connection such that a pressure surge occurring during a filling process is utilized for transferring into the collecting tank the displacing air contained in the open-mouth bag and comprising dusting product so as to receive and settle the displacing air in the collecting tank and to deposit at least part of a dust content of the displacing air in the collecting tank as deposited product.
