  However, the marking device described in Patent Document 1 requires a plurality of coloring nozzles, and there is a problem that the device becomes large. Therefore, it is conceivable to use the marking devices and methods described in Patent Documents 2 and 3. However, even with these marking methods, the loss of ink that has not been sprayed on the electric wires increases. Furthermore, the design shape of the mark in the covering portion is different in the circumferential direction of the electric wire, and the discrimination is deteriorated. In addition, it becomes difficult to control the amount of the dye ink applied, and when a large amount of the dye ink is applied, the drying property is deteriorated.

  The present invention has been made to solve such a conventional problem, and an object of the present invention is to suppress the enlargement of the apparatus, suppress the loss of in-cross and discrimination, and An object of the present invention is to provide an electric wire marking device and method capable of suppressing deterioration of drying property.

An electric wire marking device according to the present invention is an electric wire marking device for marking an electric wire covering portion, an ink tank storing dye ink, and holding dye ink supplied from the ink tank, and covering the electric wire A plurality of porous materials to be stamped with the portion sandwiched therebetween, a control means for marking each of the plurality of porous materials by moving them to the electric wire side, a plurality of porous materials are housed and each of the plurality of porous materials comprising a housing to expose a portion, the dye ink has a viscosity Ri der less 1.0 mPa · s or more 10000 mPa · s, the control means is in the standby state not subjected to marking electric wires, a plurality of porous The exposed portion of each material is brought into contact with the exposed portion of another porous material .

  According to this wire marking device, the porous material that holds the supplied dye ink sandwiches and stamps the coating portion of the wire, so there is no need to provide a plurality of colored nozzles, and the device can be kept from becoming large. Can do. In addition, since a porous material is used, dye ink is used according to the amount pressed against the wire covering portion, and it is possible to suppress in-cross and to apply a large amount of dye ink. In addition, it is possible to suppress the deterioration of the drying property. Furthermore, since it is a method of sandwiching and stamping, marking is made from both sides of the covering portion of the electric wire, and the design shape is unlikely to be different from the case of marking from one side of the covering portion with one coloring nozzle. It is possible to suppress a decrease in discrimination.

Accordingly, it is possible to suppress the increase in size of the apparatus, to suppress a decrease in in-cross and discriminability, and to suppress deterioration in dryness. Furthermore, in the standby state where no marking is applied to the electric wires, the exposed portions of each of the plurality of porous materials are brought into contact with the exposed portions of the other porous materials. Can be suppressed.

  In the wire marking device, the dye ink is an alcohol-based dye ink, the viscosity is 2.0 mPa · s or more and 5.0 mPa · s or less, and the dye is 1% by weight or more and 10% by weight or less, The solid content is preferably 10% by weight or more and 20% by weight or less.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an electric wire marking device according to an embodiment of the present invention.

  The marking device 1 for the electric wire 100 shown in FIG. 1 performs marking for identifying the electric wire on the covering portion of the electric wire 100, and includes an ink tank 10 for storing the dye ink and a felt for guiding the dye ink in the ink tank 10. The unit 20 includes two stamp units 30 and a housing 40. The marking device 1 has a function of receiving a command from a control unit (control unit (not shown)) and moving the stamp units 30 in a direction toward and away from each other.

  The ink tank 10 contains dye ink inside and has a substantially funnel shape. A lid member 11 is provided on the large-diameter opening portion 10a side of the funnel. The ink tank 10 has a felt portion 20 connected to the small diameter opening portion 10b side. The dye ink in the ink tank 10 penetrates into the felt part 20 from the small diameter opening part 10b side. When the amount of the dye ink 10 inside the ink tank 10 becomes small, the lid member 11 can be removed to add the dye ink. The ink tank 10 is not limited to the addition type, and may be a cartridge type. Furthermore, the ink tank 10 is not limited to the shape shown in FIG. 1 and may have other shapes.

  The felt unit 20 supplies the dye ink from the ink tank 10 to the stamp unit 30. The felt part 20 may be anything provided with a capillary gap, for example, a fiber bundle resin processed body, a fiber bundle heat fusion processed body, a felt processed body, a felt needle punch processed body, and a porous bubble of a synthetic resin. Examples thereof include a porous material such as a body, or an extruded body of a synthetic resin having an axial ink guide path. The material can be a synthetic fiber resin such as acrylic fiber or polyester fiber. Moreover, the felt part 20 may provide the outer skin which consists of synthetic resin films etc. in the outer peripheral surface.

  The stamp part 30 is composed of a porous material, and for example, acrylic fiber, polyester fiber, nylon (registered trademark) fiber, and vinylon fiber are used as raw materials, and harmful raw materials are hardened with resin or sintered. Things are used. The stamp unit 30 is connected to the opposite side of the felt unit 20 to the ink tank 10 and holds the dye ink supplied from the ink tank 10 through the felt unit 20. Moreover, this stamp part 30 is arrange | positioned so that the electric wire 100 may be pinched | interposed up and down, and it is driven by the control part and is moved to the coating | coated part side of the electric wire 100. FIG.

  FIG. 2 is a partially enlarged view of the stamp unit 30 shown in FIG. As shown in FIG. 2, the stamp portion 30 has a configuration in which the tip is exposed to the outside from the opening 41 formed in the housing 40, and the exposed portion contacts the coating portion of the electric wire 100 and attaches the dye ink. It is the composition which makes it. In FIG. 2, only one stamp unit 30 is illustrated, but the same applies to the other stamp unit 30. That is, each of the two stamp portions 30 is housed in the housing 40 and a part of each is exposed.

  The housing 40 includes a guide part 42. The guide part 42 is a protrusion that protrudes from the vicinity of the opening 41 of the housing 40 toward the arrangement side of the electric wire 100. This guide portion 42 is controlled so that the pushing amount into the electric wire 100 is 1.0 mm or less. That is, when marking the covering portion of the electric wire 100, the porous material is not pressed against the covering portion beyond 1 mm, and an appropriate stamp is realized.

  The outline of the marking method of the electric wire 100 is as follows. FIG. 3 is an operation diagram showing a marking method of the electric wire 100, and shows a state of the apparatus at the time of marking. When marking the covering portion of the electric wire 100, the two stamp portions 30 are moved in a direction approaching each other according to a command from the control portion. Thereby, the stamp part 30 contacts the electric wire 100 (refer FIG. 3). And marking is given. Thereafter, the two stamp portions 30 are moved away from each other according to a command from the control portion (see FIG. 1). Thereby, the stamp part 30 is separated from the electric wire 100.

  As described above, since the stamping is performed by sandwiching the covering portion of the electric wire 100, it is not necessary to provide a plurality of coloring nozzles, and the increase in size of the apparatus can be suppressed. In addition, since a porous material is used for the stamp portion 30, dye ink is used according to the amount pressed against the coating portion of the electric wire 100, which can suppress in-cross and a large amount of dye ink. The deterioration of drying property can be suppressed. Furthermore, since it is a method of inserting and stamping, marking is performed from both sides of the covering portion of the electric wire 100, and the design shape is different from the case of marking from one side of the covering portion with one coloring nozzle. It is difficult to suppress a decrease in discrimination.

  Furthermore, in this embodiment, the stamp part 30 is as follows in a standby state in which no marking is applied to the covering part of the electric wire 100. FIG. 4 is an operation diagram showing the marking method of the electric wire 100 and shows the apparatus state in the standby state. As shown in FIG. 4, when the two stamp units 30 are in a standby state, the two stamp units 30 are moved toward each other in response to a command from the control unit. At this time, the stamp part 30 is moved in a direction closer to each other and comes into contact with the stamp part 30 than when marking the covering part of the electric wire 100. As a result, each of the stamp portions 30 comes into contact with the exposed portion of the other stamp portion 30, so that the entire circumference is covered with the housing 40. Therefore, in this embodiment, drying of the dye ink is prevented.

  Furthermore, in this embodiment, the dye ink has a viscosity of 1.0 mPa · s or more and 10,000 mPa · s or less. If the viscosity is less than 1.0 mPa · s, the fluidity of the liquid increases and the surface tension decreases, so that the dye ink cannot accumulate in the porous material and causes ink leakage. . Further, when the viscosity exceeds 10,000 mPa · s, the penetration into the porous material becomes extremely slow, or the dye ink cannot be supplied utilizing the capillary force of the porous material.

  In particular, the dye ink is an alcohol-based dye ink. Thereby, the ink for general stationery can be applied. In this case, it is desirable that the porous material constituting the stamp part 30 has alcohol resistance. This is because when a general alcohol-based dye ink is used, it is possible to suppress a situation where the porous material becomes hard and deforms, and the durability is lowered.

  The dye ink preferably has a viscosity of 2.0 mPa · s to 5.0 mPa · s. This is because, when the viscosity is 2.0 mPa · s or more and 5.0 mPa · s or less, an appropriate coating film can be formed after coating, and good discrimination and drying properties can be obtained.

  Moreover, it is preferable that dye is 1 to 10 weight% in dye ink. This is because if the dye content is 1% by weight or more and 10% by weight or less, the color will not be too dark or too light after coating, and good discrimination can be achieved.

  Further, the dye ink preferably has a solid content of 10% by weight to 20% by weight. This is because if the solid content is less than 10% by weight, the film thickness after coating becomes thin and the color becomes thin. On the other hand, if the solid content exceeds 20% by weight, the film thickness after coating becomes thick, the color becomes dark, and good discrimination cannot be achieved.

  Next, the number of uses will be described. In the present embodiment, since the porous material is alcohol-resistant (for example, PE), the number of uses for marking the coating portion is also excellent.

  For example, when polyvinyl chloride is used for a porous material (pore diameter 70 μm, porosity 75%), the stamp portion 30 is hardened and deformed by marking about 300,000 times. On the other hand, when PE was used as the porous material (pore diameter: 10 μm, porosity: 64%), the stamp part 30 did not become hard even after about 600,000 markings, and the deformation was not so much observed.

  FIG. 5 is a diagram showing the electric wire 100 marked by the marking device 1 for the electric wire 100 according to the present embodiment. According to this embodiment, it is possible to mark a color pattern in which the circuit information (that is, the type of electric wire) is known on the covering portion of the electric wire 100. For example, as shown in FIG. 5, circuit information can be given to the electric wire 100 by applying dots 101 to the terminal portions and applying dots 102 to the intermediate portion between the terminals. Although not shown in FIG. 5, characters can be marked or symbols can be marked. It is also possible to mark a simple dot.

  As described above, according to the marking device and method for the electric wire 100 according to the present embodiment, a plurality of colored nozzles are used to stamp the covering portion of the electric wire 100 with the porous material that holds the supplied dye ink. The size of the apparatus can be suppressed. In addition, since a porous material is used, the dye ink is used according to the amount pressed against the covering portion of the electric wire 1000, and the in-cross can be suppressed and a large amount of the dye ink is applied. The deterioration of drying property can also be suppressed. Furthermore, since it is a method of inserting and stamping, marking is performed from both sides of the covering portion of the electric wire 100, and the design shape is different from the case of marking from one side of the covering portion with one coloring nozzle. It is difficult to suppress a decrease in discrimination.

  Accordingly, it is possible to suppress the increase in size of the apparatus, to suppress a decrease in in-cross and discriminability, and to suppress deterioration in dryness.

  Further, since the dye ink is an alcohol-based dye ink, a general stationery ink can be applied. In addition, the viscosity is 2.0 mPa · s or more and 5.0 mPa · s or less, the dye is 1% by weight or more and 10% by weight or less, and the solid content is 10% by weight or more and 20% by weight or less. It can have good discrimination.

  In addition, since the porous material has alcohol resistance, when a general alcohol-based dye ink is used, the porous material is hardened and deformed, and the durability is reduced. can do.

  Also, in the standby state where no marking is applied to the electric wire, the exposed portions of the plurality of porous materials are brought into contact with the exposed portions of the other porous materials, so that the exposed portions are exposed to the outside air of the porous material in the standby state and dried. Can be suppressed.

  As described above, the present invention has been described based on the embodiment, but the present invention is not limited to the above embodiment, and may be modified without departing from the gist of the present invention.
