Description

Technical Field

[0001] This invention relates to a method for manufacturing cardboard boxes. Background Technology

[0002] A cardboard box is a box or container, usually made of cardboard, and sometimes of corrugated fiberboard. Many types of cardboard boxes are used for packaging. Sometimes cardboard boxes are also called cartons.

[0003] Cardboard boxes are a type of packaging used for food, pharmaceuticals, hardware, and many other types of products. Folded cardboard boxes are typically assembled into tubes at the manufacturer's location and then shipped flat to the packer.

[0004] Cardboard boxes have been used since at least the late 19th century to separate different types of goods and to improve the logistics process.

[0005] Over the past few decades, the steady growth of e-commerce has led to a significant increase in the number of cardboard boxes shipped each year. This is because every specific item shipped to a customer, including one or more physical products, must be individually packaged, for example, in a cardboard box. The box is then either transported by a freight delivery service to a local delivery point and ultimately picked up by the individual end customer, or delivered directly to the end customer's mailbox or doorstep by the same service. Conversely, when individual end customers purchase their goods in person at a physical store and then have those goods delivered to their homes using their own vehicles, cardboard boxes are unnecessary.

[0006] Numerous facts demonstrate that cardboard boxes often contain a significant amount of unused volume because standard boxes are most commonly used. These standard boxes are not sized optimally for the intended contents. In other words, a large amount of air is transported from the warehouse to the end customer. This situation can also be rephrased as unoptimized transportation from the warehouse to the end customer. If freight transportation were better optimized, e-commerce businesses, shipping companies, and customers could all benefit economically.

[0007] Due to global warming, many governments and large economic alliances have now set stringent targets to reduce greenhouse gas emissions. The transportation sector has been identified as a priority sector because it accounts for a large portion of total greenhouse gas emissions.

[0008] The dramatic increase in cardboard boxes, for example due to the steady growth of e-commerce, has offset efforts to reduce greenhouse gas emissions.

[0009] If some dimensions of the raw materials for cardboard boxes can be standardized, thereby optimizing the logistics and manufacturing process of the raw materials, this would be a significant advantage.

[0010] Therefore, it is necessary to reduce a relatively large amount of unnecessary air transport by optimizing carton dimensions, for example, based on the expected contents. At the same time, it is necessary to standardize certain dimensional aspects of the carton raw materials in a smart way, thereby optimizing the raw material logistics and the manufacturing process itself. Summary of the Invention

[0011] One object of the present invention is to provide a method for manufacturing cardboard boxes that can reduce unnecessary and relatively large amounts of air transport, thereby reducing greenhouse gas emissions, and that standardizes certain dimensional aspects of the raw materials for cardboard boxes, thereby optimizing the logistics of the raw materials used for cardboard boxes and the manufacturing process of the cardboard boxes themselves.

[0038] According to a second aspect, the present invention relates to a computer program product comprising encoded instructions, which, when executed in a processor, are used to implement the above-described method.

[0039] According to a third aspect, the present invention relates to a computer-readable medium storing the aforementioned computer program product.

[0040] According to a fourth aspect, the present invention relates to a carton manufacturing system, the system comprising a sheet assembly unit and a sheet attachment unit.

This further supports the goal of reducing the relatively large amount of air transported unnecessarily, thereby reducing greenhouse gas emissions. Some regulations require manufacturers to minimize cardboard box size to reduce carbon emissions when transporting the final cardboard box; these requirements can be met using this method.

[0042] The computer-aided material handling system can provide data regarding, for example, the dimensions of the intended contents. The control unit then calculates the dimensions required for the first and second carton panels to fit together with the intended contents. The control unit can also provide data regarding, for example, the required dimensions of a removable carton panel assembly to fit the intended contents.

[0043] Humans can directly provide data about, for example, the expected size of the contents through the user interface.

[0047] Width cutting units and length cutting units can be contained in a single unit.

[0048] Width cutting unit, length cutting unit, and final cutting unit can be contained in one unit.

[0049] The intended contents may include one or more physical objects.

[0050] The raw materials for cardboard boxes can be individual sheets, sheets that are connected and folded together, or continuous rolls.

[0051] Attachment methods can include, for example, glue, tape, or clips.

[0052] Adhesives can be glue or tape, etc.

[0053] This system can certainly handle more carton sheets than the first and second carton sheets.

[0054] In addition to the steps described, the system can also control and manage the placement of the intended contents into the final carton or refined final carton, and subsequently close the final carton or refined final carton.

[0055] The set of measurements for the expected contents may include, for example, the width, length, and height of the expected contents, as well as other measurement parameters.

[0056] The width of the cardboard strip can be, for example, “X” = x*(y^n), where x>0, n = 0, 1, 2, 3…, and y = 2.

[0057] Theoretical Example 1 / 1: For x = 1, y = 2: For n = 0, then x0 = 1; for n = 1, then x1 = 2; for n = 2, then x2 = 4; for n = 3, then x3 = 8; for n = 4, then x4 = 16, and so on. For x = 2, y = 2: For n = 0, then x0 = 2; for n = 1, then x1 = 4; for n = 2, then x2 = 8; for n = 3, then x3 = 16; for n = 4, then x4 = 32, and so on. For x = 4, y = 2: For n = 0, then x0 = 4; for n = 1, then x1 = 8; for n = 2, then x2 = 16; for n = 3, then x3 = 32; for n = 4, then x4 = 64, and so on.

[0058] The width of the cardboard strip can be, for example, “X” = x*(y^n), where x>0, n = 0, 1, 2, 3…, and y = 4.

[0059] Application Example 1 / 3: For x = 4 cm, a total width of 76 cm is needed. For x = 4, y = 4: For n = 0, then x0 = 4; for n = 1, then x1 = 8; for n = 2, then x2 = 16; for n = 3, then x3 = 32; for n = 4, then x4 = 64, and so on. Therefore, we need the following cardboard strips: cut out a 64 cm wide strip, leaving 12 cm (78-64); cut out an 8 cm wide strip, leaving 4 cm (12-8); cut out a 4 cm wide strip, leaving 0 cm (4-4).

[0060] Application Example 2 / 3: For x = 4 cm, a total width of 48 cm is needed. For x = 4, y = 4: for n = 0, then x0 = 4; for n = 1, then x1 = 8; for n = 2, then x2 = 16; for n = 3, then x3 = 32; for n = 4, then x4 = 64, and so on. Therefore, we need the following cardboard strips: cut out a 32 cm wide strip, leaving 16 cm (48-32); then cut out another 16 cm wide strip, leaving 0 cm (16-16).

[0061] Application Example 3 / 3: For x = 4 cm, a total width of 50 cm is needed. If x = 4, then the possible widths X are multiples of 4. Therefore, we need to choose the first value greater than 50 that is a multiple of 4, which is 52 in this example. For x = 4, y = 4: For n = 0, then x0 = 4; for n = 1, then x1 = 8; for n = 2, then x2 = 16; for n = 3, then x3 = 32; for n = 4, then x4 = 64, and so on. Therefore, we need the following cardboard strips: cut out a 32 cm width, leaving 20 cm (52-32); cut out a 16 cm width, leaving 4 cm (20-16); cut out a 4 cm width, leaving 0 cm (4-4).
