Methods and a machine for forming a container from a blank

摘要

A machine a mandrel assembly includes a mandrel having an external shape complimentary to an internal shape of at least a portion of a container, a first lift mechanism operatively coupled to a first servomechanism to wrap a first portion of a blank about the mandrel, a second lift mechanism operatively coupled to a second servomechanism to wrap a second portion of the blank about the mandrel, and a folding arm coupled to the first lift mechanism and operatively coupled to a third servomechanism. A control system is in communication with the first servomechanism, the second servomechanism, and the third servomechanism and is configured to transmit a signal to each of the servomechanisms to independently control movement of the first lift mechanism, the second lift mechanism, and the folding arm to wrap at least the first and second portions of the blank about the mandrel to form the container.

主权项

1. A machine for forming a container from a blank of sheet material, said machine comprising:
a frame; a mandrel assembly mounted to the frame, the mandrel assembly comprising:
a mandrel having an external shape complimentary to an internal shape of at least a portion of the container;a first lift mechanism operatively coupled to a first lift servomechanism and configured to wrap a first portion of the blank about the mandrel;a second lift mechanism operatively coupled to a second lift servomechanism and configured to wrap a second portion of the blank about the mandrel; anda folding arm coupled to the first lift mechanism and operatively coupled to a folding arm servomechanism, the first lift mechanism configured to move the folding arm relative to the mandrel;a lateral presser arm coupled to the second lift mechanism and operatively coupled to a lateral presser servomechanism, the lateral presser arm configured to rotate with respect to the second lift mechanism to wrap the second portion of the blank about the mandrel; and a control system in communication with the first lift servomechanism, the second lift servomechanism, the folding arm servomechanism, and the lateral presser servomechanism, the control system configured to transmit a signal to each of the servomechanisms to control at least one of a speed and a timing of movement of the first lift mechanism, the second lift mechanism, the folding arm, and the lateral presser arm independently of each other to wrap at least the first and second portions of the blank about the mandrel to form the container.
