Description

i APPLICATION APPARATUS AND APPLICATION METHOD Field of the Invention The invention relates to an application apparatus and an application method.

Field of the Invention In order to identify the purposes of use and the like of an electric wire, an electric wire marking apparatus that improves a marking operation by dye ink (application) on a coated part of an electric wire is known as an example of an apparatus for application. As the electrical wire marking apparatus, an apparatus has been suggested that ejects ink to an electrical wire from a plurality of dye nozzles positioned opposite the electrical wire that is supplied (eg, PTL 1). Also, an apparatus that performs a marking operation by ejecting ink to an electrical wire from a dye nozzle has also been suggested (e.g., PTL 2 and 3).

Appointment List [Patent Literature] [PTL 1] JP-A-2008-93617 [PTL 2] J P-A-6- 190341 [PTL 3] WO 2004/015721 Brief Description of the Invention Technical Problem According to the marking devices described in PTL 1 to 3, since the ink is ejected from the nozzles, an ink loss is caused by the ink that has not colored the electric wire.

Thus, a marking operation is considered in which the ink is impregnated into a porous member having flexibility and the porous member is brought into contact with the coated portion of the electric wire thereby coloring ink thereto. However, since the infiltration of the ink into the porous member is performed by a capillary force, it is difficult to perform a marking operation in which high viscosity ink having low infiltration performance is used.

Meanwhile, the above problem is not limited to the marking apparatus and the method of dyeing the electrical wire with ink and is common to other apparatus and method of application. That is, the above problem also occurs in an application apparatus and an application method by applying a high viscosity resin (e.g., a subcoating agent) or the high viscosity coating agent to an electrical wire.

It is therefore an advantageous aspect of the present invention to provide an application apparatus and an application method capable of enabling optimization when a high viscosity liquid agent is applied to a part coated with an electric wire.

Solution to the problem According to an advantage of the invention, an application apparatus for applying a liquid agent to a coated part of an electric wire is provided, the application apparatus comprising: a liquid agent tank configured to accommodate a liquid agent therein, and includes a pressurization mechanism configured to pressurize an interior of the liquid agent tank; Y a porous member configured to contact a coated part of the electric wire by holding the liquid agent supplied from the liquid agent tank, in order to apply the liquid agent to the coated part, wherein the liquid agent tank supplies the liquid agent to the porous member by pressurizing the pressurization mechanism.

The application apparatus may further comprise a felt portion provided between the liquid agent tank and the porous member, and configured to absorb the liquid agent supplied from the liquid agent tank and to filter-deliver the liquid absorbent agent to the porous member.

According to another advantage of the invention, an application method for applying a liquid agent to a coated part of an electric wire is provided, the method of application comprising: a first process for pressurizing an interior of a liquid agent tank, which accommodates the liquid agent therein, by means of a pressurization mechanism of the liquid agent tank and thus supplies the liquid agent; Y a second process for maintaining the liquid agent, which is supplied in the first process, in a porous member and carries the porous member that holds the liquid agent in contact with the coated portion of the electric wire.

Advantageous effects of the invention According to the application apparatus, the liquid agent is supplied to the porous member by pressurization of the pressurization mechanism. Therefore, even when the high viscosity liquid agent having low infiltration performance is used, the liquid agent is sufficiently supplied to the porous member. Thus, an application defect is difficult to occur and it is possible to allow optimization when the high viscosity liquid agent is applied to the coated part of the electric wire.

According to the application apparatus, the felt part is interposed between the liquid agent tank and the porous member. Therefore, compared to a configuration where the liquid agent is delivered directly to a movable porous member, since the liquid agent once infiltrates the non-moving felt part, it is possible to make it difficult for a liquid agent leak happen Also, when the part of felt, the liquid agent must be made to smoothly infiltrate the felt part, which makes it more difficult to perform the application operation by means of high viscosity liquid agent. However, even in this case, it is possible to sufficiently supply the high viscosity liquid agent by adjusting a pressurization force or pressurization time of the pressurization mechanism. Therefore, while suppressing leakage of the liquid agent, it is possible to allow for optimization when the high viscosity liquid agent is applied to the coated part of the electric wire.

According to the application, the liquid agent is supplied to the porous member by pressurization of the pressurization mechanism. Therefore, even when the high viscosity liquid agent having low infiltration performance is used, the liquid agent is sufficiently supplied to the porous member. Thus, an application defect is difficult to occur and it is possible to allow optimization when the high viscosity liquid agent is applied to the coated part of the electric wire.

According to the invention, it is possible to provide an application apparatus and an application method capable of enabling optimization when a high viscosity liquid agent is applied to a part coated with an electric wire.

Detailed description of the invention Below, a preferred exemplary embodiment of the invention will be described with reference to the drawings. Fig. 1 is a schematic configuration view showing an example of an application apparatus according to an illustrative embodiment of the invention. In the following, a marking apparatus that performs a marking operation on a part coated with an electric wire will be exemplified. However, it should be noted that the application apparatus is not limited to the marking apparatus.

A marking apparatus (application apparatus) 1 of an electric wire 100 shown in FIG. 1 performs an operation marking for identification of the electric wire in a coated part of the electric wire 100 and includes an ink tank (liquid agent tank) 10 which is accommodated in the same ink (liquid agent of high viscosity as UV curing ink and the like) , two stamping parts (porous members) 20, a felt part 30 guiding the ink in the ink tank 10 and a housing 40.

The ink tank 10 is for accommodating the ink therein and has a substantial funnel shape having a large diameter opening 10a and a small diameter opening 10b. The felt part 30 is inserted through the small diameter opening 10b of the ink tank 10 and the ink in the ink tank 10 infiltrates from the small diameter opening 10b to the stamp portions 20 through the felt 30. Also, the ink tank 10 is configured so that when the ink in the ink tank 10 reaches a predetermined amount, a cover member (a member also serves as a pressurization mechanism 1 1 which will be described below). ) on the side of the large diameter opening 10b is separated to supplement the ink. Meanwhile, the ink tank 10 is not limited to the type of supplement and can be a type of cartridge. Also, the ink tank 10 is not limited to the shape and the like shown in Fig. 1 and other forms can also be adopted.

The stamp portions 20 are made of a porous material, for example, a material that is obtained by using an acrylic fiber, a polyester fiber, a nylon fiber (registered trademark) or a vinylon fiber as a raw material and solidification of the fiber with a resin or fiber sintering.

The stamp portions 20 contain and hold therein the ink supplied from the ink tank 10. Also, the stamp portions 20 are positioned to vertically sandwich the electric wire 100 therebetween and are urged to move in a direction approaching each other by a controller. That is, the stamp portions 20 move to vertically sandwich the electrical wire 100. Thus, the stamp portions 20 come into contact with the coated portion of the electrical wire while holding the ink therein and apply the ink to the part coated to thus perform the marked 15. Meanwhile, it is shown in the sectional view of Fig. 1 that the two stamp parts 20 are separated from each other. However, the stamp parts are presently formed in a U-shape or grooved shape and are thus integrally configured. Therefore, the ink supplied to the upper stamp portion 20 also infiltrates the lower stamp portion 20.

The felt part 30 which is interposed between the ink tank 10 and the stamp portions 20, absorbs the ink that is supplied from the ink tank 10 and supplies the ink 25 absorbed to the stamp parts 20. Any felt part 30 can be used to the extent that it has a capillary pore space. For example, a resin body processed from a fiber bundle, a thermal melt body processed from a fiber bundle, a processed felted body, a felt needle needle-punched body, a porous material such as the porous foam body, A synthetic resin, an extrusion body molded from a synthetic resin having an axial ink guide path and the like can be adopted. As the material thereof, a synthetic fiber resin such as acrylic resin, polyester resin and the like can be used. Also, the felt part 30 can be provided at an outer periphery thereof with an outer coating made of a synthetic resin, metal film or the like.

Also, in this illustrative embodiment, the ink tank 10 has a pressurization mechanism 1 1. The pressurization mechanism 1 1 is a plunger that can be moved from the large diameter opening 10a of the ink tank 10 to the small diameter opening 10b. The plunger moves towards the small diameter opening 10b, thereby pressurizing an interior of the ink tank 10.

Fig. 2 is a partial enlarged view of the stamp portion 20 shown in FIG. 1. As shown in Fig. 2, the stamp part 20 is configured so that a main end thereof is exposed to the outside through an opening 41 formed in the housing 40 and the exposed part is placed in contact with the coated part of the electric cable 100 to thereby fix the ink thereto. Meanwhile, only one stamp 20 is shown in FIG. 2. However, the other stamp part 20 is also the same. That is, each of the two stamp portions 20 is accommodated by the housing 40 and a portion thereof is exposed.

Also, the housing 40 has a guide portion 42. The guide portion 42 is a protrusion projecting from a vicinity of the opening 41 of the housing 40 to an arrangement side of the electrical wire 100. By the guide portion 42, a amount of indentation to electric wire 100 is controlled to be 1.0 mm or smaller. That is, when the coated part of the electric wire 100 is marked, a suitable stamping is implemented while the porous material is not printed to the coated part with 1 mm excess.

In the following, the supply of ink in the ink tank 10 is described. First, the ink is accommodated in the ink tank 10. Then, the pressurization mechanism 11 is operated. That is, the plunger moves towards the small diameter opening 10b, thereby pressurizing the interior of the ink tank 10. Thus, even when the high viscosity ink is accommodated in the ink tank 10, the ink of high viscosity sufficiently infiltrates the felt part 30.

Then, the ink reaches the stamp portions 20 of the felt part 30. Here, since the ink infiltrates sufficiently in the felt part 30, the ink correctly infiltrates the stamp parts 20. That is, it is possible to supply the stamp portions 20 with sufficient ink to perform the marking.

Subsequently, a method of marking the electric wire 100 is described. Fig. 3 is an operational view showing a method of marking the electric wire, showing a state of the apparatus after marking. When the coated portion of the electric wire 100 is marked, the two parts of the stamp 20 move in one direction and approach each other by an instruction from the controller. In this way, the stamp portions 20 are brought into contact with the electric wire 100 (see Fig. 3), so that the marking is implemented. After this, the two stamp portions 20 move in a direction 15 away from each other by an instruction from the controller (see Fig. 1). In this way, the stamp parts 20 are separated from the electric wire 100.

In this way, since the stamping is performed with the coated part of the electric wire 100 that is interleaved, or it is not necessary to provide a plurality of dye nozzles, so that it is possible to suppress the apparatus that will be enlarged. In addition, since the embossing parts 20 are made of the porous material, the ink is used depending on the printed grade to the coated part of the electrical wire 100, to suppress an ink loss. Also, since the wire electrical is stamped with intercalation, the coated part of the electric wire 100 is marked on both sides thereof. Therefore, compared to a configuration where the coated part is marked from one direction by a dye nozzle, it is possible to suppress the identification that will be reduced.

Further, in this illustrative embodiment, the stamp portions 20 are subjected to a following state in a waiting state where marking is not performed for the coated portion of the electric wire 100. FIG. 4 is an operational view showing the method of electrical wire marking, which shows an apparatus state in a waiting state. As shown in Fig. 4, the two stamp parts 20 move in one direction approaching each other by an instruction of the controller in a standby state. At this time, the stamp parts 20 move in the direction of each other closer than the state where the coated portion of the electric wire 100 is marked, so that they are brought into contact with each other. Thus, the exposed part of a stamp portion 20 contacts the exposed portion of the other stamp portion 20, so that the substantially complete peripheries thereof are covered by the housing 40. Therefore, in this illustrative embodiment, the ink is prevented from drying out in the stamp portions 20. Meanwhile, the invention is not limited to the configuration where the entire peripheries of the stamp portions 20 are covered by the housing 40. Even when the peripheries The entire parts are not covered by the housing 40, the ink is prevented from drying out in the parts where the stamp parts 20 come into contact with each other.

Meanwhile, in this illustrative embodiment, since the UV curing ink is used as the ink, the ink tank 10 is preferably formed by a material that blocks the ultraviolet radiation. In this way, the curing of the ink is prevented, so that it is possible to avoid that the infiltration of the same is further reduced. Likewise, the housing 40 is also preferably configured by the material that blocks the ultraviolet radiation.

Fig. 5 shows the electric wire 100 which is marked by the marking apparatus 1 of an electric wire according to the illustrative embodiment. In accordance with this illustrative embodiment, it is possible to mark a color pattern, which allows a user to know the circuit information (ie, a type of electrical wire), in the coated part of the electric wire 100. For example, as shown in FIG. shown in Fig. 5, it is possible to provide the electric wire 100 with the circuit information by means of the marking points 101 at the terminal parts and the points 102 at an intermediate part between the terminals. Meanwhile, although not shown in Fig. 5, it may be possible to mark a letter or a symbol. Also, it may be possible to mark simple scattered dots.

Thus, according to the marking apparatus 1 and the method of electric wire 100 of this illustrative embodiment, the ink is supplied to the stamp portions 20 by pressurizing the pressurization mechanism 1 1. Therefore, even when the high viscosity ink having low infiltration performance is used, the ink is sufficiently supplied to the stamp portions 20. Thus, an application defect is difficult to occur and it is possible to allow the optimization when the high viscosity ink is marked on the coated part of the electric wire.

Also, the felt part 30 is interposed between the ink tank 10 and the stamp parts 20. Therefore, compared to a configuration where the ink is supplied directly to the movable stamp parts 20, since the ink is once infiltrates the felt part 30 that does not move, it is possible to make it difficult for ink leakage to occur. Also, when the felt part 30 is interposed, the ink should be made to infiltrate smoothly into the felt part 30, which makes it more difficult to perform the application operation by the high viscosity ink. However, even in this case, it is possible to sufficiently supply the high viscosity ink by adjusting the pressurization force or by pressurizing the time of the pressurization mechanism 1 1. Therefore, while the leakage of the ink is suppressed, it is possible to allow optimization when marking the high viscosity ink in the coated part 25 of the electric wire.

Although the invention has been described based on the illustrative embodiment, the invention is not limited to the above illustrative embodiment and the illustrative embodiment can be changed without departing from the essence of the invention.

For example, in the above illustrative embodiment, the marking apparatus 1 and the method of the electric wire 100 have been exemplified. However, the invention is not limited to the marking apparatus 1 and method of the electric wire 100 and can be applied to a apparatus and an application method for applying a high viscosity resin as the subcoating agent to the electric wire 100 or an apparatus and an application method for applying a high viscosity coating agent, which covers a mark, to the electric wire 100 .
