AI Technical Summary

Technical Problem

The existing self-propelled package machines require manual operator intervention during the package process and cannot achieve full automation.

Method used

Using an anchoring element including a first grasping unit and a second grasping unit, the automatic initial sheet-shaped part of the film is achieved through the electromagnetic device and the fork-shaped element, and the configuration changes of the locking element and the base are automatically completed. the packaging process.

Benefits of technology

A fully automated film wrapping process is achieved without operator intervention, ensuring the firmness and stability of the wrapping.

Abstract

A self-propelled wrapping machine (1) movable around a load (100) on a support plane (P) for wrapping the load with a membrane (50), the self-propelled wrapping machine comprising: an anchoring element (30) comprising a base (33) adapted to abut against the support plane (P) and connected to an upper plate (32), and a locking element (35) interposed between the upper plate (32) and said base (33), the locking element (35) and the base (33) are movable relative to each other between a closed configuration (C), in which the locking element and the base abut against each other, and an open configuration (A), in which the locking element and the base are spaced apart from each other; a first gripping unit (5) movable and configured to, in an initial step of the wrapping cycle, position and release an anchoring element (30) located on the support plane (P) in the vicinity of the load (100), the anchoring element being associated with an initial sheet (50a) of the membrane blocked between the locking element (35) arranged in the closed configuration (C) and the base (33), and to release the anchoring element (30) from the initial sheet (50a) of the membrane blocked between the locking element (35) arranged in the closed configuration (C) and the base (33); in the open configuration (A), the anchoring element (30) is gripped and lifted and the locking element (35) and the base (33) are moved to release the initial sheet (50a) of the membrane after the self-propelled wrapping machine (1) travels around the load (100) for at least one turn while wrapping the load with the membrane (50); the first gripping unit (5) comprises first gripping means (6) and second gripping means (16), which are selectively and alternately activated to engage and grip the upper plate (32) or the locking element (35), respectively.
