Abstract

PURPOSE: To provide a cable having characters or labels that have functions of both visibility and complete printing by printing plural sizes of identification characters or labels on the same surface. CONSTITUTION: The size of an identification character or label 8 as required for visibility is determined with the width of contact between a planographic roll and the conductor 7 of a cable serving as a reference. The size of an identification character or label 9 as required for the completeness of printing is determined as that capable of being printed with 100% certainty while fluctuations in the relative positions of the planographic roll and the cable during printing are taken into account. The large identification character or label 8 and the small identification character or label 9 are continuously printed on the same surface of the conductor 7. Therefore, for identification the most visible can be selected from various sizes of identification characters or labels, and the complete identification characters or labels can surely be printed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire or cable having characters or signs for quality assurance or identification.

[0002]

2. Description of the Related Art Conventionally, an electric wire or a cable (hereinafter, referred to as a cable) for identifying characters (including numbers) or a sign (hereinafter, these are collectively referred to as a sign) has no missing mark. The size that can be surely printed was selected according to the thickness of the cable, and the same size sign was printed on the surface of the cable.

Markings on a cable are printed by, for example, a flat printing roll 2 having markings 4 and the like as shown in FIG.
The ink 3 is placed by means of a spatula 5 and the cable 1 is inserted between the printing roll 2 and the underroll 6 and the printing roll 2 is pressed against the surface of the cable 1 to transfer the marker. The cross-sectional shape of the cable 1 is generally circular, and printing can be performed only in a limited range where the pressed printing roll 2 and the surface of the cable 1 are in contact with each other. For this reason, although a curved surface printing method that uses a surface of a printing roll that matches the curvature of the cable surface has been proposed,
The number of printing rolls must be prepared according to the type of cable, which is expensive. For this reason, printing is generally performed using the flat printing roll 2 described above. In this printing, in consideration of variations in the relative positions of the flat printing roll 2 and the cable 1 during printing, the size of the mark for achieving 100% complete printing is limited to a smaller size. It will be.

[0004]

When a manufacturer guarantees the printing quality of a sign, it requires perfect printing without missing marks, so it is inevitable that a small size sign on the safety side will be selected and added. Will be done. However, from the user's point of view, this sign is provided for identifying the wire core and the cable, and it is important in handling that it is as large and easy to see as possible. Therefore, the above-mentioned problems of the conventional technology make it difficult to match the requirements of both the manufacturer and the user side.

The present invention has been made in view of the above-mentioned problems, and solves the problems of the prior art, and has both the function of being easy to see and the function of being provided with completeness such that a mark is not missing. It is intended to provide a cable with a marked sign.

[0006]

SUMMARY OF THE INVENTION The gist of the present invention is demanded from a mark of a size (of a size that can be easily visually recognized) required for easy viewing as described above, and a completeness without defects. One is to print two or more types of markings on one and the same cable, one with a smaller (optimized compared to the former) size. That is, it is a cable with multi-size characters in which a flat printing roll is applied and a plurality of sizes of identifying characters or signs are printed on the same surface. The position having the character or mark is the cable with multi-size characters on the surface of the insulator or the surface of the sheath, and the cable with multi-size characters is continuously arranged on the same line. Then, a cable with multi-size characters in which a plurality of sizes of identifying characters or signs are printed on separate lines by each flat printing roll is provided.

[0007]

The function of the size of the sign, which is required from the viewpoint of visibility, is not particularly limited because perfection in manufacturing is not required, but it is not limited by the customer's request or the contact width between the flat printing roll and the cable. Can be used as a guide. Even if the mark is lacking, it is sufficient that the print quality is secured to the extent that the whole mark can be inferred from a part thereof.

The mark size required for completeness is determined as a 100% reliable printable size in consideration of variations in the relative positions of the flat printing roll and the cable during printing. That is, the contact width between the flat printing roll and the cable, the variation in the relative position of the flat printing roll and the cable, etc. are determined under the manufacturing conditions such as the size, shape, material of the cable and the pressing pressure of the flat printing roll. You must use a standard size optimized for.

Marks of two or more sizes are continuously engraved on the same flat printing roll and printed simultaneously, or marking printing rolls of respective sizes are prepared and separated. It may be printed on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cable with multi-size characters of the present invention will be described below with reference to the drawings. FIG.
[Fig. 4] is an external view of a cable core when it is applied to the numbering of the core 7 of one embodiment. That is, a large marker 8 and a small marker 9 are formed on the surface of the wire core 7 by printing continuously at the same time. These signs 8 and 9 are formed by printing two kinds of signs 8 and 9 of a large size and a small size continuously using the same flat printing roll on which two kinds of signs are engraved. The large marker 8 is formed on the surface of the core 7 by being cut off, while the smaller marker 9 is completely printed and formed.

Another embodiment will be described with reference to FIG. This case is also a case where the numbering is applied to the line core 7. That is, the large mark 8 and the small mark 9 are provided in parallel in the width direction of the wire core 7 by separate flat printing rolls.

In any of the above cases, the larger label 8 is a label that is partially cut off and the integrity of the label is impaired, but it is a legible label, and it is sufficient that the content is a label that can be sufficiently inferred. . On the other hand, the smaller marker 9 is smaller and harder to see than the larger marker 9, but since it is not 100% chipped, even if there is concern about grasping the contents of the larger marker 8, the line center 7 The confirmation can be surely confirmed by the smaller mark 9. On the manufacturer's side, quality assurance can be performed with this smaller complete mark 9.

Regarding the sizes of the two markers as described above, the smaller marker 9 is for satisfying the function of perfection, and the upper limit thereof is optimized depending on the manufacturing conditions. On the other hand, the larger sign 8 fulfills the function of legibility, and the smaller sign 9 for the sake of certainty.
The size is relatively large, so that the function of being easy to see is satisfied. As a printing method, it is more efficient to print by printing two types of markers on the same flat printing roll of the example shown in FIG.
However, even in the example shown in FIG. 2, it is possible to reduce the number of printing operations by means such as double-sided simultaneous printing.

In the above two examples, two types of markings, large and small, are provided on the surface of the insulator of the cable core, but they may be provided on the cable sheath as well. Also, the case of two types of labels has been described, but this need not be limited to two types. That is, FIG. 3 shows an example in which markers 10 of various sizes are continuously formed on the core 7. In this case, one of the smaller signs only needs to fulfill the integrity function. The effect is that the same printing roll can be used to print cables of various sizes. On the other hand, from the user's point of view, there is an advantage that the most visible sign can be selected and identified from the signs of many sizes.

[0015]

As described above, according to the cable with multi-size characters of the present invention, the size of the sign can be made sufficiently large, the cable can be easily identified, and the work efficiency can be improved. Can be improved. In particular, it has an excellent effect of assisting a person who has difficulty in visually identifying a fine sign. From the user's point of view, there is an advantage that you can select the most visible sign from many sizes and identify and work. on the other hand,
The manufacturer can print the complete sign,
Thereby, the excellent quality assurance function can be displayed.
