FIELD OF THE INVENTIONThe invention relates to a method for packaging a container and, more particularly, to a method for packaging a container using a robotic arm.
BACKGROUNDSystems used to automatically package a product into a container are known in the art. The known systems commonly include a robotic arm and a vision device. The robotic arm has an end effector, such as fingers or a suction device, directly interfacing with the product and used to secure the product to the robotic arm in a fixed orientation. The robotic arm moves the product to the container under the guidance of the vision device.
A known container 10 according to the prior art used in such a packaging system is shown in
The known container 10 is commonly sized to closely fit a product in the product receiving space 16, avoiding movement of the product within the known container 10 during transport. However, when the robotic arm moves the product toward the product receiving space 16 in the height direction H, the product frequently contacts a top edge of the top flaps 14 due to the close relative sizes of the product and the product receiving space 16. Contact with the top edge of the top flaps 14 during insertion requires stopping the packaging process and manually correcting the relative orientation of the product and the known container 10, decreasing manufacturing efficiency.
To address the problem of the product contacting the top flaps 14, complex end effectors of robot arms have been developed capable of tilting the held product in addition to moving the product in a fixed horizontal orientation in a three-dimensional coordinate system. The robotic arm moves the product toward the product receiving space 16 in a tilted orientation, lowers the product into the product receiving space 16, then returns the product to the horizontal orientation. These complex end effectors, however, are substantially more expensive than end effectors that are only capable of moving the product in a fixed orientation, requiring additional parts and maintenance costs.
SUMMARYA container for packaging a product is provided with a plurality of side panels, a plurality of first top flaps, and a plurality of second top flaps. The plurality of side panels includes a first side panel, a second side panel, a third side panel, and a fourth side panel. The plurality of first top flaps, one first top flap extending from a top side of each of the first side panel and the second side panel to a first height. The plurality of second top flaps, one second top flap extending from a top side of each of the third side panel and the fourth side panel to a second height greater than the first height.
The invention will now be described by way of example with reference to the accompanying figures, of which:
Exemplary embodiments of the present invention will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to like elements. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
A container 100 according to the invention is shown in
A blank of the container 100 is shown in
The plurality of side panels 110, as shown in
In the embodiment shown in
The first top flaps 120 and the second top flaps 130, as shown in
As shown in
As shown in
The bottom flaps 140, as shown in
The attachment tab 150 is attached to the second end 104 of the side panels 110, also the second end 114d of the fourth side panel 110d, and extends away from the side panels 110 in the longitudinal direction L. In the shown embodiment, the attachment tab 150 is formed in a trapezoidal shape. In other embodiments, the attachment tab 150 may be any shape known to those with ordinary skill in the art and capable of performing an attachment to assemble the container 100 as described below.
The blank of the container 100 shown in
The first side panel 110a is folded along the second end 114a to be perpendicular to the second side panel 110b, the second side panel 110b is folded along the second end 114b to be perpendicular to the third side panel 110c, and the third side panel 110c is folded along the second end 114c to be perpendicular to the fourth side panel 110d. The attachment tab 150 is folded along the second end 104 to be perpendicular to the fourth side panel 110d and is attached to a surface of the first side panel 110a. The attachment tab 150 is attached to the first side panel 110a by a tape, a liquid adhesive, plastic welding, metal welding, or any other form of attachment known to those with ordinary skill in the art.
The bottom flaps 140 are folded along the bottom sides 118 to be perpendicular to the side panels 110. The bottom flaps 140 are attached to one another or to the side panels 110 by a tape, a liquid adhesive, plastic welding, metal welding, or any other form of attachment known to those with ordinary skill in the art.
The assembled container 100, as shown in
A system 200 according to the invention for packaging the container 100 is shown in
The conveyor belt 230 extends parallel to the roller track 240 as shown in
The robot arm 210 and vision device 220, as shown in
The robot arm 210 and end effector 212 operate under guidance of the vision device 220, and in the shown embodiment, the vision device 220 is a camera. In other embodiments, the vision device 220 may be a laser displacement sensor or any other type of vision device used in the guidance of robot arms and known to those with ordinary skill in the art.
A method of using the system 200 to package the container 100 will now be described with reference to
The product P has dimensions closely matching the dimensions of the product receiving space 160. The product P, as shown in
The first step is shown in

In the third step shown in
In the fourth step shown in
In the fifth step shown in
In the sixth and final step shown in
It is further noted that the container 100 is oriented so long as the robot 210 is told what the orientation of the container 100 is. This could be a fixed orientation or it could be variable with some means (i.e., a sensor) of detecting the container 100 orientation and reporting to the robot 210.
The foregoing illustrates some of the possibilities for practicing the invention. Many other embodiments are possible within the scope and spirit of the invention. It is, therefore, intended that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention is given by the appended claims together with their full range of equivalents.
