Embodiment Construction

[0028] There is provided an unpacking device for taking out a plastic bag from a package formed of a cut cardboard box, lifting the plastic bag, and taking out contents from the plastic bag by using an articulated robot.

[0029] In this embodiment, it is assumed that food as a material is put into a snack production line. The packaging states available when receiving food will be described below.

[0030] figure 1 and figure 2 It is a figure which schematically shows the packing process of a food. Such as figure 1 shown, as the content of food 1 (see figure 1 left in ) is contained in a plastic bag 2 as primary packaging material (see figure 1 central plot in ). The take-off (bag opening) 6 is folded to form a primary package 3 (see figure 1 right picture in ). Such as figure 2 As shown, the primary packaging 3 is packed into a cardboard box 4 as secondary packaging material (see figure 2 left figure in ), thus forming a secondary package 5 (see figure 2 right ...

Abstract

An unpacking device (100) unpacks a package and takes out contents. The package includes a primary package (3) formed by packing the contents with a primary packing material and a secondary package (5) formed by packing the primary package (3) with a secondary packing material. The secondary packing material of the secondary package (5) has an incision (8). The unpacking device (100) includes a robot (10), and a control unit (110, 120) for controlling the robot (10) such that the robot (10) takes out the primary package (3) through the incision (8) of the secondary packing material and then takes out the contents from the primary package (3).

Description

technical field [0001] The present invention relates to an unpacking device and an unpacking method for unpacking and taking out contents, and articles unpacked by the unpacking device and unpacking method; When the debris of the packaging material is mixed into the content of the technology. Background technique [0002] Materials that go into the production line are usually received in a packaged state. The packaged materials are manually unpacked by workers and put into the production line. Much of the unpacking work is performed repeatedly and in many cases automated. [0003] An unpacking device for taking out the contents by cutting the packaging material with a sharp object is disclosed in Japanese Patent Application Publications Nos. 2002-002638 and 2002-249116. In the unpacking device of JP2002-002638A, the contents (old newspapers) are cut at the same time as the packing material is cut. In the unpacking device of JP2002-249116A, the upper wall of the box is cu...
