Description

  The present invention relates to an apparatus for marking identification information on a cable surface and a marking method thereof.

  Conventionally, various means have been adopted to facilitate identification of cables to be laid. For example, a technique is adopted in which seals, name tags, and the like are attached to both ends of the cable (the secondary side of the load center panel switch and the primary side of the main switch of the load distribution board).

However, with this technology, if the number of cables increases, the intended use cannot be determined, so if you try to attach name tags, etc. to the cables to be laid at regular intervals, the work becomes extremely complicated. When the book was also laid, there was a problem that the name tags and the like were peeled off due to the rubbing of the cables.

In order to solve this problem, a technique of printing cable identification information on the cable surface using an ink jet printing apparatus is used. For example, in a cable laying information printing device disclosed in Patent Document 1, a cable introduction unit, a printing unit, a speed detection unit, and a cable feeding unit are arranged in series on a platform of a gantry, and the cable feeding unit is further provided. A cable is configured to travel and move on the printer head by a ball wire drawing machine.

  Subsequently, the traveling speed of the cable is detected by the encoder of the speed detector, and the personal computer calculates the traveling distance of the cable based on the output of the encoder, and the laying information and the print command are sent to the ink jet printer for each predetermined traveling distance. Is output. As a result, the laying information is printed at a predetermined pitch on the surface of the cable via the printer head. According to this technique, the laying information can be easily printed for each cable based on the laying information list at the site.

  In addition, a technique of printing cable identification information on the cable surface using a laser-type printing apparatus is also used. For example, the cable laying method and the cable number printing device disclosed in Patent Document 2 are provided with a device for measuring the cable length and a device for printing the cable number in the process of drawing the cable from the drum and laying it, The cable number planned in advance for each installed cable is stored in the computer, and the cable number is printed by the laser method for each predetermined length of the cable pulled out from the drum. It has a means to apply.

  According to this technology, the cable can be identified by looking at any part of the installed cable, and when conducting cable maintenance work for aged plant, cable survey and labor costs, cable number card affixing work, etc. The work of attaching the cable number tag with a string can be omitted, and the cable number can be recognized by looking at a certain length of the cable during the work. It is said that there is an effect of improvement, and the cable number is printed by a laser, so that it does not disappear during the work, and it is possible to work continuously after cutting.

  In addition, as a general technique, it is known that a method of printing (marking) identification information on the surface of various media using a hot stamp device is known. In other words, stamp means consisting of a stamping board (made of metal or rubber) of characters etc. (identification information) set in a hot stamping device in advance, and a hot stamping tape (a film layer for printing on a PET film) In this state, the medium is pressed against the surface of the medium, and identification information is printed (marked) on the surface of the medium.

  Although the techniques described above are certainly considered to be resistant to improved workability and deterioration of printed identification information, they have been found to have drawbacks. That is, according to the ink jet printing apparatus, it takes a considerable time for the identification information printed on the cable surface to harden. Therefore, if the cables are rubbed before the hardening, the identification information on the cable surface is obtained. However, the possibility of disappearing is extremely high.

In addition, laser-based printing devices require laser output control. If the setting is incorrect, there is a high possibility that not only the cable surface but also the cable core will be burned. If the length is different or the cable is set incorrectly, the laser may reach the core of the cable. Ink-jet and laser-type printing devices, due to the complexity of their mechanical construction, have a decisive defect in field work that the size of the printing device itself becomes extremely large and lacks portability. I know it.

In addition, when trying to print identification information on the cable surface using a conventional hot stamping device, the stamping board and the cable surface are usually in point contact, and the identification information to be printed is missing. Occurs. Further, in order to prevent the loss of identification information, the stamping board must be strongly pressed against the cable surface, which causes a problem that the cable itself is damaged.

Here, in order to solve these problems of missing identification information, the stamping board must be shaped along the curved surface of the cable surface, and when printing on multiple cables with different curved surface shapes, each shape In addition, it is necessary to prepare a stamping board that meets the requirements in advance, and the stamping board corresponding to the required characters must be replaced each time. It is obvious that the work cost is extremely high.

In general, the hot stamping apparatus must set the temperature for heating the stamping board to be very high (if the stamping board is not heated to a high temperature (usually about 200 ° C.), the printing performance on the medium will be high. For example, when printing is performed on the job site, there is a drawback that the worker is in danger (that is, it is unsuitable for work on the job site).

  The present invention is an improvement of the drawbacks of the above-described conventional printing apparatus and printing method, and can be marked with identification information by thermal transfer at regular intervals during the work of drawing from the cable drum, and is extremely excellent in portability. This is a cable marking device that simplifies work, and further provides a technique that can identify cable identification information (information about the purpose of use, etc.) in a short time and eliminates accidental disconnection when the cable is discarded. And it is providing the cable marking apparatus which becomes difficult to lose | disappear the identification information marked on the cable surface. Furthermore, since it is not necessary to use a stamping board like a conventional hot stamping device, it is possible to prevent marking and identification information from being lost at a much safer temperature, and greatly increase the cost of work. It is an object of the present invention to provide an apparatus and a method that can be reduced.

In order to achieve the above object, the present invention takes the following technical means.
That is, the invention according to claim 1 is a cable placement holding means for placing and holding a cable, and a sheet holding means for holding a winding marking sheet on which cable identification information corresponding to the cable is printed in advance. And a sheet collecting means for winding and collecting the marking sheet supplied from the sheet holding means, and a thermal head that can be heated to a predetermined temperature. The thermal head is pressed against the cable placed and held on the cable placement and holding means with the marking sheet from the sheet holding means to the sheet collecting means interposed. The cable attribute information printed in advance on the marking sheet. A thermal transfer means for transferring heat to the surface; and provided in the thermal transfer means and driven in conjunction with the thermal transfer means to rotate the sheet recovery means and cause the sheet recovery means to wind up and recover the marking sheet. A cable marking device having a sheet collection control mechanism for controlling.

  The invention according to claim 2 is the cable marking device according to claim 1, wherein the cable mounting and holding means has a cable cradle, and the cable cradle corresponds to a surface shape of the cable. The thermal head has a cross-sectional arc shape corresponding to the surface shape of the cable. The invention according to claim 3 is the cable marking device according to claim 1 or 2, further comprising a base on which the cable placement holding means is placed and fixed, wherein the base includes the cable receiver. A cable placement assisting tool for holding and fixing the cable is provided at a position having a predetermined gap on both sides in the longitudinal direction of the table.

  Furthermore, the invention according to claim 4 is the cable marking device according to any one of claims 1 to 3, wherein a surface of the thermal head that presses the cable is provided with thermally conductive silicon rubber. It is characterized by having. The invention according to claim 5 is the cable marking device according to any one of claims 1 to 4, further comprising an urging unit that urges the thermal transfer unit to the initial position. The means is characterized by comprising a biasing spring.

  Further, the invention according to claim 6 is a cable marking method for marking the cable identification information on the cable surface, wherein the marking sheet on which the cable identification information is printed in advance and wound is used as a sheet holding means. A step of holding, a step of winding the marking sheet held by the sheet holding unit around the sheet collecting unit at a position spaced apart from the sheet holding unit, and placing the cable on a cable cradle. In the state where the thermal head is moved from the initial position by moving the thermal head from the initial position, the portion of the marking sheet from the sheet holding means to the sheet collecting means is interposed. The marking sheet with heat applied to the thermal head. The sheet collection information is obtained by thermally transferring the identification information of the cable printed in advance on the surface of the cable, moving the thermal transfer means to the initial position, and driving the thermal transfer means in conjunction with the thermal transfer means. And a step of rotating the means and causing the sheet collecting means to wind up and collect the marking sheet for a predetermined length.

  According to the cable marking device of the present invention, since the cable surface can be marked using a marking sheet on which cable identification information has been printed in advance, it is necessary to use a stamping board like a conventional hot stamping device or marking method. As a result, it is possible to set the temperature required for marking to be low (conventionally about 200 ° C. is required at a temperature of 130 ° C. to 140 ° C., preferably 135 ° C. according to the technique of the present invention. I know that.) Further, since thermal transfer is performed at a temperature in this range, the identification information transferred by heat transfer is instantly cured and marking resistant to rubbing becomes possible.

  And since a marking sheet pre-printed with cable identification information can be used, it can easily handle various markings such as characters, information, colors, cartoons, etc., compared to a hot stamping device using a conventional stamping board. (In particular, in the conventional hot stamping apparatus, since the hot stamping foil is only one color, it is difficult to mark various colors together, and it is also possible to mark pictures such as comics. It is difficult.) Cost can be greatly reduced.

  Further, according to the cable marking device of the present invention, the marking performance can be remarkably improved as compared with the conventional ink jet method or laser method (deterioration or disappearance of the marked identification information is extremely small). Furthermore, since the apparatus can be made smaller than the ink jet method or the laser method, it is excellent in portability, and it is possible to make marking work on site very easy.

  Furthermore, according to the cable marking device of the present invention, the thermal head that performs thermal transfer is formed in a circular arc shape corresponding to the shape of the cable surface. Marking on curved surfaces that have been difficult can be made easy (the stamping board makes point contact with the cable surface (curved surface), so the characters to be marked may be lost. In addition, if the loss is to be prevented, an excessive pressing force must be applied to the cable, resulting in cable damage.)

And since the heat conductive silicone rubber is provided in the surface which presses a cable of a thermal head, while being able to improve the adhesiveness to a cable, damage to a cable can be prevented. Moreover, since the cable cradle for placing the cable has a triangular cross-sectional groove corresponding to the shape of the cable surface, it is also possible to prevent the cable from shifting during marking.

In addition, it is preferable to provide the cable mounting auxiliary base 28 at substantially the same height as the cable receiving base 13. Furthermore, the sheet collecting means 16 is provided at the sheet holding means 14 holding the marking sheet 18 and at a position facing it (in this embodiment, a position facing the thermal transfer means 22). The sheet collecting means 16 can, for example, hold the marking sheet 18 supplied from the sheet holding means 14 and take up and collect it.

  A thermal transfer means 22 equipped with a thermal head 20 is provided, and the cable 24 is received with the marking sheet 18 interposed by holding the arm 24 and lowering the thermal transfer means 22 from the initial position. The cable is configured to press a cable placed on the table 13.

Then, one end of the marking sheet 18 is wound around the sheet collecting means 16. The marking sheet 18 is made of a PET film, and cable identification information is printed on the film surface.

Subsequently, a cable K for marking the identification information is provided on the both sides in the longitudinal direction of the cable cradle 13 with a predetermined gap (substantially the same height as the cable cradle 13). And is fixed on the cable holder 13 and fixed on the cable cradle 13. The cable cradle 13 uses a cable mounting side having a cross-sectional groove corresponding to the shape of the cable K to be marked (a cross-sectional triangular groove along the cable direction) to prevent the cable K from shifting. It is possible to do. In addition, the cross-sectional shape groove | channel of the cable stand 13 is not restricted to a triangular groove | channel, For example, as long as it is a shape which can prevent the shift | offset | difference of the cable K, such as a triangular trapezoid groove | channel, any shape may be sufficient as it.

First, identification information for marking a cable is printed on the marking sheet 18 in advance. Since printing can be performed in advance, for example, it is possible to overcome the problems of the conventional hot stamping apparatus in which the stamping board must be replaced at the time of marking.

  In addition, since various information can be printed on the marking sheet 18, for example, a cable marking that has never been possible, such as a colorful image, a colorful character, a cartoon, etc. It has become possible to expand the nature. Furthermore, since the preprinted material is thermally transferred, it is not necessary to use a high temperature as in a conventional hot stamping device (device using a stamping board).

  Next, as shown in the drawing, the sheet holding means 14 is provided in the cable marking device 10 in a state where the marking information 18 on which the identification information is printed and wound is held.

Further, the cable is pressed against the cable for a predetermined time with the marking sheet 18 interposed as it is. Then, the cable identification information printed on the marking sheet 18 is thermally transferred to the cable surface by the heat applied to the thermal head 20.

A thermally conductive silicone rubber 36 is attached to the surface of the thermal head 20 that presses the cable. Therefore, when marking on the cable surface (when pressing), the cable can be prevented from being damaged, and furthermore, the adhesion to the cable is improved, so that high quality marking can be performed. ing.

  The identification information thus thermally transferred is extremely excellent in marking quality, and it has been found that even after a long period of time has elapsed after the cable has been laid, its deterioration can be suppressed considerably. Since the temperature for heating the thermal head is set in the range of 130 ° C. to 140 ° C., more preferably 135 ° C., the safety in field work is further improved (the temperature is set in this range). Thus, by performing thermal transfer, the identification information that has been thermally transferred is instantly cured, and marking resistant to rubbing is possible.)

Next, a marking operation on the cable will be described with reference to FIG.
FIG. 6 is a view showing an embodiment of the cable marking device according to the present invention, and shows a state of marking on the cable surface. In addition, (a) is a perspective view, (b) is a front view. Reference numeral 10 denotes a cable marking device, 12 denotes a cable placement holding means, 13 denotes a cable receiving base, 28 denotes a cable placement auxiliary base, 30 denotes a clasp, K denotes a cable, and D denotes a cable drum.

  First, pull out the cable K from the cable drum D around which the cable K to be marked is wound, and set it on the cable marking device 10 (holding and fixing to the cable placement auxiliary base 28 using the clasp 30; Set on the cable cradle 13 provided on the cable mounting and holding means 12). Then, the cable is marked as described above. After the marking at the predetermined position is completed, the cable K can be pulled out from the cable drum D again and the marking operation can be continued.

Since the marking work can be performed using a marking sheet on which cable identification information is preliminarily printed, the present invention is extremely suitable when it is necessary to mark various types of identification information. In addition, since high-temperature heating is not required and the device itself is small, it is extremely useful when working on site.
