Abstract

An opening system including a cutting device for cutting an adhesive tape; a suctioning and lifting device for suctioning a upper panels, which are separated from each other because the adhesive tape is cut by the cutting device; rod members which are elongated to be inserted into gaps, when the gaps are formed between the upper panels and upper edges of side surfaces in the packaging box because the upper panels are spaced apart from the side panels by the suctioning and lifting device; and an opening device which moves the respective rod members while being in contact with lower surfaces of the upper panels such that the upper panels are rotated outward with respect to boundaries between the upper panels and the side panels.

First claim

The invention claimed is:

1. An opening system of a packaging box, in which the opening system opens the packaging box including upper panels respectively extended from side panels opposite to each other to serve as an upper surface, and bonded to each other by using an adhesive tape as their end portions are in contact with each other, thereby closing the upper surface, the system comprising:
a cutting device for cutting the adhesive tape while being moved along the end portions of the upper panels, opposite to each other;
a suctioning and lifting device for suctioning the upper panels separated from each other because the adhesive tape thereon is cut by the cutting device, and pulling the upper panels upward from the packaging box for the upper panels to be spaced apart from the side panels;
rod members elongated to be inserted into gaps when the gaps are formed between the upper panels and upper edges of side surfaces of the packaging box because the upper panels are spaced apart from the side panels by the suctioning and lifting device; and
an opening device for moving the respective rod members maintained in contact with lower surfaces of the upper panels for the upper panels to be pivoted outward from their boundaries with the side panels,
wherein the packaging box includes four side panels and four upper panels each extended from the four side panels,
the upper panels include a first pair of two of the upper panels opposite to each other and a second pair of two of the upper panels opposite to each other and placed perpendicular to the first pair of the upper panels,
the first pair of the upper panels are placed on the second pair of the upper panels and bonded to each other by the adhesive tape as their end portions are in contact with each other,
the second pair of the upper panels include end portions opposite to each other, the rod members are provided for the respective upper panels,
the cutting device is provided to cut the adhesive tape bonding the first pair of the upper panels to each other, and
the suctioning and lifting device is provided to suction each of the first pair of the upper panels and the second pair of the upper panels.

2. The system of claim 1 , wherein the opening device performs a first movement for linearly moving the respective rod members outward the packaging box and a second movement for linearly moving the respective rod members downward the packaging box, and
the upper panel is opened by being pivoted from the upper surface of the packaging box in the first movement, and the upper panel is placed to be in contact with an outer surface of the side panel in the second movement.

3. The system of claim 1 , wherein the opening device includes a first driving unit driven to be adjacent to or spaced apart from the packaging box, a second driving unit coupled to and driven vertically with respect to the first driving unit, a fixed block coupled to and moved with respect to the second driving unit in a horizontal direction or at a predetermined inclination angle in the horizontal direction, and one of the rod members fixed to the fixed block and extended parallel to a direction in which the first driving unit is driven.

4. The system of claim 1 , further comprising holding means for maintaining the upper panels pivoted parallel to the side panels of the packaging box by the rod members to respectively be in close contact with the side panels.

5. The system of claim 1 , wherein the suctioning and lifting device includes vacuum aspirators spaced apart from each other and respectively vacuum-suctioning the two upper panels opposite to each other.

6. An opening system of a packaging box, in which the opening system opens the packaging box including upper panels respectively extended from side panels opposite to each other to serve as an upper surface, and bonded to each other by using an adhesive tape as their end portions are in contact with each other, thereby closing the upper surface, the system comprising:
a cutting device for cutting the adhesive tape while being moved along the end portions of the upper panels, opposite to each other;
a suctioning and lifting device for suctioning the upper panels separated from each other because the adhesive tape thereon is cut by the cutting device, and pulling the upper panels upward from the packaging box for the upper panels to be spaced apart from the side panels;
rod members elongated to be inserted into gaps when the gaps are formed between the upper panels and upper edges of side surfaces of the packaging box because the upper panels are spaced apart from the side panels by the suctioning and lifting device; and
an opening device for moving the respective rod members maintained in contact with lower surfaces of the upper panels for the upper panels to be pivoted outward from their boundaries with the side panels,
wherein the opening device performs a first movement for linearly moving the respective rod members outward the packaging box and a second movement for linearly moving the respective rod members downward the packaging box, and
the upper panel is opened by being pivoted from the upper surface of the packaging box in the first movement, and the upper panel is placed to be in contact with an outer surface of the side panel in the second movement.

7. An opening system of a packaging box, in which the opening system opens the packaging box including upper panels respectively extended from side panels opposite to each other to serve as an upper surface, and bonded to each other by using an adhesive tape as their end portions are in contact with each other, thereby closing the upper surface, the system comprising:
a cutting device for cutting the adhesive tape while being moved along the end portions of the upper panels, opposite to each other;
a suctioning and lifting device for suctioning the upper panels separated from each other because the adhesive tape thereon is cut by the cutting device, and pulling the upper panels upward from the packaging box for the upper panels to be spaced apart from the side panels;
rod members elongated to be inserted into gaps when the gaps are formed between the upper panels and upper edges of side surfaces of the packaging box because the upper panels are spaced apart from the side panels by the suctioning and lifting device; and
an opening device for moving the respective rod members maintained in contact with lower surfaces of the upper panels for the upper panels to be pivoted outward from their boundaries with the side panels,
wherein the opening device includes a first driving unit driven to be adjacent to or spaced apart from the packaging box, a second driving unit coupled to and driven vertically with respect to the first driving unit, a fixed block coupled to and moved with respect to the second driving unit in a horizontal direction or at a predetermined inclination angle in the horizontal direction, and one of the rod members fixed to the fixed block and extended parallel to a direction in which the first driving unit is driven.
