Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of embodying blanks for obtaining corrugated cardboard boxes used for packing one or more articles.

[0002] More specifically, the present invention relates to a method for embodying a blank for packing one or more articles from a corrugated cardboard sheet for packing, and to a related machine for operating this method. BACKGROUND ART

[0003] Corrugated cardboard sheets for packing can be used for various purposes, for example, for forming corrugated cardboard boxes.

[0004] In this case, it is first necessary to create folding lines, also known as score lines. The score lines divide the corrugated cardboard sheet for packing into a plurality of portions so as to obtain a blank. Cutting lines are created in a similar manner.

[0005] In this way, various portions of the blank can be easily folded along the score lines, so that a corrugated cardboard box for packing one or more articles can be obtained in a simple and quick manner, and distortion and cracks are prevented from being formed on the corrugated cardboard sheet for packing during the folding step.

[0006] To date, as known methods for embodying a blank for packing one or more articles from a corrugated cardboard sheet for packing, mechanical scoring or cutting tools such as scoring cutters, blades or knives are used to create score lines and cutting lines.

[0007] When a corrugated cardboard sheet of predetermined dimensions is fed in and each work cycle is the same, the tools are positioned and configured to always perform the same movement path. This is because they are adjusted to perform a predetermined operation on the corrugated cardboard sheet.

[0008] This embodiment imposes a limitation that, at the entrance of the machine performing the steps to materialize the blank, corrugated cardboard sheets of the same dimensions must be fed in with each work cycle. Otherwise, the materialization of the score lines or cutting lines may be incorrectly and inaccurately made, i.e., not made in the required position.

[0009] Furthermore, if corrugated cardboard sheets of a specific size are being fed in, or if corrugated cardboard sheets of different sizes are being fed in, it may be necessary to create score lines at different points on one blank and the next blank. Therefore, the tool will create score lines or cutting lines at different positions depending on the dimensions of one or more items being packed.

[0010] In this case, the mechanical scoring and cutting tools must be disassembled and rearranged and reconfigured according to the dimensions of the one or more items to be packed.

[0011] In the most extreme cases, namely when repositioning and reconfiguring mechanical cutting tools is impossible, the use of different machines may be relied upon to create scorelines precisely (i.e., in the required locations).

[0012] As an alternative to the aforementioned method, the score lines or cutting lines that appear on the blank can be made using a laser beam, and therefore using a laser-type scoring means.

[0013] However, even though laser-type scoring means can easily manage size changes by being configured to determine orientation according to the dimensions of one or more items being packed and according to the corrugated cardboard sheet, the fact that they are laser-type means that the scoring means are particularly expensive, leading to increased manufacturing costs for realizing the blanks. [Overview of the Initiative] [Problems that the invention aims to solve]

[0014] In light of the above, the object of the present invention is to eliminate the aforementioned drawbacks of the prior art. [Means for solving the problem]

[0015] The above objectives are achieved by the method according to claim 1 for creating a blank for packing one or more articles from a corrugated sheet for packaging, and by a machine that operates the method according to claim 6 for creating a blank for packing one or more articles from a corrugated sheet for packaging.

[0016] Advantageously, a scoring means comprising a first support for holding a first scoring tool and a second scoring tool, and a second support for holding a third scoring tool and a fourth scoring tool, moves along a first and second direction parallel to the direction of travel, together with the movement of the first and second scoring tools along the first support, and the movement of the third and fourth scoring tools along the second support, respectively, to embody a score line on a blank according to the detected and stored dimensions of one or more articles being packed.

[0017] This makes it easy to feed in corrugated cardboard sheets of different dimensions when creating the scoreline, thereby allowing the scoring mechanism to perform its movements according to the dimensions of one or more items being packed.

[0018] The method and machine that are the object of the present invention enable the implementation of scorelines at a lower cost than known types of methods and machines that are laser-type scoring means, while guaranteeing the same results as those obtained using known means.

[0019] Specific embodiments of the present invention will be described in the following part of the present specification, in accordance with what is defined in the claims, with the aid of the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Similarly, the second scoreline (12) can be parallel to the first direction (D1) and the second direction (D2) (see Figures 6-9).

[0027] As explained above, the blank (1) that is realized by performing the steps of this method is: In the central sector (13); A main portion (50) is formed between the fifth score line (18) and the eighth score line (21) and is sized to cover the bottom of one or more articles (3) to be packed; and comprises a first lateral portion (51) and a second lateral portion (52) on both sides of the main portion (50) with respect to the fifth score line (18) and the eighth score line (21), In the first lateral sector (14); A third lateral portion (53) is formed between the fifth scoreline (18), the eighth scoreline (21), the first lateral edge (2a) of the corrugated cardboard sheet (2), and the first scoreline (11); a first reinforcing portion (53a) and a second reinforcing portion (53b) are provided on both sides of the third lateral portion (53) with respect to the fifth scoreline (18) and the eighth scoreline (21), respectively, and the third and sixth scorelines (16, 19) are embodied therein.

[0028] The corrugated cardboard sheet (2) can be in the form of a continuous corrugated cardboard strip.

[0029] In this case, the corrugated cardboard sheet (2) can be divided according to the dimensions of one or more items (3) to be packed inside.

[0030] Alternatively, the corrugated cardboard sheet (2) can be in the form of a divided corrugated cardboard sheet.

[0031] Figures 2 to 4 illustrate the steps for feeding in the corrugated cardboard sheet (2).

[0032] Figure 2 illustrates a conveyor (23) feeding corrugated cardboard strips.

[0033] Figures 3 to 5 illustrate examples of divided corrugated cardboard strips.

[0034] The movement steps of the first support (5) and the second support (8) can be performed when the corrugated cardboard sheet (2) is assumed to be in a fixed position, or when the corrugated cardboard sheet (2) is moving along the direction of travel (D).
