Fully automated bag preparing system for various types of bags

摘要

A displacement device is for preparing a bag for its installation at a filling point (or second location) of packaging equipment. The displacement device grabs the bag from the pick-up location (or stack) (at which first position and orientation parameters have been previously measured), displaces the bag while measuring second position and orientation parameters of the bag, adjusting the operation and displacement of the displacement device for displacing and installing the bag at the filling point; at the same time, the measurement of the next bag's first position and orientation parameters is done to adjust the operation and displacement of the displacement device for grabbing the next bag on the stack. Such a double location evaluation, which is concomitant on two different bags, allows savings in processing time.

主权项

1. A bag preparing system comprising:
a displacement device for displacing a bag while continuously holding the bag between a pick-up location and a filling point of the bag, the displacement device comprising a gripper for gripping the bag during displacement of the bag; a first measurement system for measuring, at the pick-up location, a pick-up position parameter indicative of the pick-up location, and for generating a first signal indicative of the pick-up position parameter; a second measurement system for measuring, at an intermediate location between the pick-up location and the filling point while the bag is held by the displacement device, at least one of an intermediate position parameter and an intermediate orientation parameter indicative of an intermediate position and an intermediate orientation of the bag, respectively, and for generating a second signal indicative of said at least one of the intermediate position parameter and the orientation parameter; and a controller for controlling operation and displacement of the displacement device, said controller adjusting the operation and the displacement of the displacement device for gripping the bag at the pick-up location based on the first signal, and for displacing the bag towards the filling point based on the second signal.
