METHOD FOR CONVEYING IN A PACKAGING LINE FLEXIBLE PACKAGING HELD SUSPENDED, DEVICE SUITABLE FOR IMPLEMENTING SAID METHOD, AND MACHINE COMPRISING SAID DEVICE

摘要

A transportation method for the intermittent, forward moving transportation of flexible containers suspended in a packaging line, including the use of movable arms on a same plane, between which a container is secured in opposite areas, one of which is a tractor arm and the other a push arm. Between two consecutive stops, the method includes steps of simultaneously moving the tractor arm and push arm forwards at different velocities, in order to deform the container and move the contents to compensate for the forces of inertia. Also disclosed is a device for putting the method into practice, including a number of guides that determine a closed route, upon which at least a first and second adjacent carrying element slide, which may be operated independently or together, in order to be moved along the length of the guides and work together to jointly secure and transport a corresponding container.

主权项

1. A transportation method for the intermittent, forward moving transportation of flexible containers (2) held suspended in a packaging line, comprising the use of pairs of movable arms on a same movement plane, between which a container (2) is secured in opposite areas, one of which is a tractor arm (5b) and the other a push arm (5a), wherein in a forward moving cycle, between two consecutive stops during the transportation of a container, the method comprises the steps of:
a) simultaneously moving the tractor arm (5b) at a velocity v2 and the push arm (5a) at a velocity v1 forward, thus fulfilling the mathematical relation V1>v2 and b) simultaneously moving the tractor arm (5b) at a velocity v2 and the push arm (5a) at a velocity v1 forward, thus fulfilling the mathematical relation V2>v1.
