  Such marking apparatuses described in Patent Documents 1 to 3 include an ink tank that receives ink to be applied to an electric wire. This ink tank is directly attached to the main body together with the coloring nozzles, etc., which increases the weight of the main body and increases the size of the main body, which requires a sufficient facility space for installation of the apparatus. End up.

  Furthermore, since the ink tank is directly attached to the main body, when the marking apparatus is in operation, there is a possibility that ink supply failure or ink leakage may occur due to vibration of the apparatus.

  In addition, the said problem is a problem common not only to the marking apparatus which colors an electric wire to an electric wire but other coating apparatuses. That is, it is a problem common not only to ink but also to a coating apparatus that applies a resin such as a primer or a liquid agent such as a coating agent to an electric wire.

  The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to prevent the facility space from becoming excessive, as well as poor supply of liquid agent and liquid agent leakage. An object of the present invention is to provide a coating apparatus capable of suppressing the possibility of the occurrence of water.

  The coating device of the present invention is a coating device that applies a liquid agent to a coating portion of an electric wire, and contacts the coating portion of the electric wire while holding the liquid agent tank that receives the liquid agent and the liquid agent fed from the liquid agent tank.

  According to this coating apparatus, the liquid agent tank includes the flexible tube that is interposed between the liquid agent tank and the main body portion and has flexibility to guide the liquid agent from the liquid agent tank to the porous member side in the main body portion. Without attaching itself to the main body, the liquid agent can be supplied to the porous member in the main body through the flexible tube. For this reason, a main-body part will shrink and it can prevent that an installation space will become excessive. Even if vibration is generated by the operation for the porous member to contact the covering portion, the liquid agent tank is not attached to the main body itself and is connected through a flexible tube. It becomes difficult to transmit to the tank, and the supply failure of the liquid agent and the occurrence of the liquid agent leakage due to vibration can be suppressed.

  In the coating apparatus, it is preferable that the main body portion further includes a felt portion that absorbs the liquid agent sent through the flexible tube and supplies the absorbed liquid agent to the porous member.

  According to this coating apparatus, the main body portion further includes a felt portion that absorbs the liquid agent sent through the flexible tube and supplies the absorbed liquid agent to the porous member. For this reason, the liquid agent received in the liquid agent tank reaches the felt part through the flexible tube, and is guided from the felt part to the porous member. Thereby, it is not necessary to directly attach the flexible tube to the operating member (and the surrounding operating member) called the porous member, and it is possible to prevent the flexible tube from being detached due to repeated operations.

  In the coating apparatus, the felt part absorbs the liquid agent and permeates and supplies the porous member with the permeation supply part, and covers the outer periphery of the permeation supply part and partially opens to expose a part of the permeation supply part. It is preferable that the main body portion further includes a leakage liquid agent holding portion that holds the liquid agent leaking from the opening of the felt portion.

  According to this coating apparatus, since it further includes a leakage liquid agent holding part that holds the liquid agent leaking from the opening of the felt part, when the liquid agent is excessively supplied to the felt part and the liquid agent overflows, the liquid agent Is held by the leakage liquid agent holding part. Thereby, the situation where the liquid agent is supplied excessively to a porous member and the application failure with respect to an electric wire covering part generate | occur | produces can be suppressed.

  Moreover, in the coating apparatus, it is preferable that the main body portion further includes a casing that covers the felt portion and the leakage liquid agent holding portion.

  According to this coating apparatus, the main body portion further includes a casing that covers the felt portion and the leaked liquid agent holding portion, so that the possibility that the liquid agent held by these adheres to an operator or the like can be reduced. .

  In the coating apparatus, the housing preferably has an air hole that allows communication between the outside and the inside.

  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 illustrating an example of a coating apparatus according to an embodiment of the present invention. In the following description, a marking device that performs marking on the covering portion of the electric wire will be described as an example. However, the coating device is not limited to the marking device.

  A marking device (coating device) 1 for an electric wire 100 shown in FIG. 1 performs marking for identifying an electric wire on a covering portion of the electric wire 100, and includes an ink tank 10 and a main body portion 20.

  The ink tank 10 receives ink (liquid agent) inside and has a substantially funnel shape having a large-diameter opening portion 10a and a small-diameter opening portion 10b. The small diameter opening portion 10 b side is connected to the main body portion 20 through a flexible tube 30 described later, and the ink in the ink tank 10 is fed from the small diameter opening portion 10 b side to the main body portion 20. Further, the ink tank 10 is configured such that when the amount of ink inside becomes small, the ink can be added by removing the lid member 11 on the large diameter opening portion 10a side. 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 main body portion 20 performs marking by coloring the ink fed from the ink tank 10 on the covering portion of the electric wire 100, and includes a stamp portion (porous member) 21.

  The stamp portion 21 is made of a porous material, and for example, acrylic fiber, polyester fiber, nylon (registered trademark) fiber, and vinylon fiber are used as raw materials, and the raw materials are hardened with resin or sintered. Things are used. The stamp unit 21 holds the ink contained in the liquid fed from the ink tank 10. Moreover, this stamp part 21 is arrange | positioned so that the electric wire 100 may be pinched | interposed up and down, and it is driven by a control part and is moved to the direction which mutually approaches. That is, the stamp part 21 is moved so as to sandwich the electric wire 100 from above and below. Thereby, the stamp part 21 will contact the coating | coated part of the electric wire 100 in the state hold | maintained ink, and will color and mark an ink for a coating | coated part. Although the two stamps 20 are illustrated apart from each other in the cross section shown in FIG. 1, the two stamps 20 are actually formed in a U shape, a concave shape, or the like, and they are integrated. For this reason, the ink supplied to the upper stamp unit 21 penetrates and is supplied to the lower stamp unit 21.

  Further, in the present embodiment, the marking device 1 includes a flexible tube 30 interposed between the ink tank 10 and the main body 20. The flexible tube 30 is for guiding the ink from the ink tank 10 to the stamp portion 21 side of the main body portion 20, and has flexibility and bends freely. For this reason, the ink in the ink tank 10 reaches the flexible tube 30 from the small diameter opening portion 10 b side and is supplied to the main body portion 20 through the flexible tube 30.

  As described above, since the flexible tube 30 is provided between the ink tank 10 and the main body portion 20, even if the stamp portion 21 is moved, the vibration is not easily transmitted to the ink tank 10, and ink leakage or ink due to the vibration is prevented. It becomes difficult for supply failure to occur. Furthermore, since the ink tank 10 is connected via the flexible tube 30, it is not necessary to attach the ink tank 10 to the main body 20, and the main body 20 can be reduced in weight. In addition, since the main body 20 can be prevented from being enlarged, the marking device 1 can be installed without installing the main body 20 and the ink tank 10 separately to secure sufficient equipment space. Good.

  Furthermore, the main body portion 20 of the marking device 1 according to the present embodiment includes a felt portion 22, a leaked ink holding portion (leakage liquid agent holding portion) 23, and a casing 20a covering these.

  FIG. 2 is an enlarged view showing the felt portion 22 shown in FIG. 1 and its surroundings. The felt portion 22 absorbs ink sent through the flexible tube 30 and permeates and supplies the absorbed ink to the stamp portion 21. The felt part 22 is composed of a permeation supply part 22a that absorbs and supplies ink to the stamp part 21, and a covering member 22b that covers the outer periphery of the permeation supply part 22a.

  The permeation supply unit 22a only needs to have 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 member such as a body, or an extruded body of a synthetic resin having an ink guide path in the axial direction. The material can be a synthetic fiber resin such as acrylic fiber or polyester fiber. The ink supplied through the flexible tube 30 reaches the stamp unit 21 by the permeation supply unit 22a.

  The covering member 22b is an outer skin that covers the outer peripheral surface of the permeation supply portion 22a. The covering member 22b is made of a synthetic resin film or a metal tube. Furthermore, the covering member 22b is partially cut away to form an opening 22c.

  The leaked ink holding portion 23 is provided in a cylindrical shape on the outer peripheral side of the felt portion 22 and has a defined space portion S. The space S faces the opening 22c of the felt part 22. For this reason, even if the ink is excessively supplied to the felt part 22 and the ink leaks from the opening 22c, the leaked ink reaches the leaked ink holding part 23 and is held. As a result, the possibility of color defects due to excessive supply of ink is reduced. More specifically, since the marking device 1 according to this embodiment supplies ink to the main body 20 via the flexible tube 30, the ink viscosity changes due to a change in ambient temperature, or the ink tank 10. An excessive supply of ink may occur due to a change in pressure inside. However, in the marking device 1 according to the present embodiment, the leaked ink holding unit 23 holds the ink that has been supplied excessively and leaked, so that the possibility of occurrence of poor coloring due to excessive supply is reduced. .

  Further, in the present embodiment, the felt part 22 and the leaked ink holding part 23 are covered with a casing 20a. As a result, the felt part 22 and the leaked ink holding part 23 are exposed to prevent the ink from adhering to the worker or the like.

  Here, if the felt part 22 and the leaked ink holding part 23 are covered with the casing 20a, the pressure in the ink tank 10 may decrease, and ink supply may be insufficient. That is, when the amount of ink decreases in the sealed ink tank 10, the pressure in the ink tank 10 decreases. Therefore, it becomes difficult for the ink to be supplied to the felt part 22, and there is a possibility that the supply of ink will be insufficient. Therefore, in the present embodiment, an air hole 20b is formed in the housing 20a. The air hole 20b allows the inside and the outside of the housing 20a to communicate with each other. Even if the amount of ink in the sealed ink tank 10 is reduced, air reaches the ink tank 10 from the air hole 20b through the felt part 22 and the flexible tube 30, and a pressure drop in the ink tank 10 is prevented. As a result, the possibility of ink supply shortage is reduced.

  Next, operation | movement of the marking apparatus 1 of the electric wire 100 is demonstrated. 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 21 are moved in a direction approaching each other according to a command from the control portion. Thereby, the stamp part 21 contacts the electric wire 100 (refer FIG. 3), and marking is given. Thereafter, the two stamp portions 21 are moved away from each other by a command from the control portion (see FIG. 1). Thereby, the stamp part 21 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. Moreover, since the porous member is used for the stamp part 21, ink will be used according to the part pressed against the coating | coated part of the electric wire 100, and an in-cross can be suppressed. Furthermore, since it is a method of sandwiching and stamping, marking is performed from both sides of the covering portion of the electric wire 100, and the discrimination is reduced as compared with the case of marking from one side of the covering portion with one coloring nozzle. Can be suppressed.

  Furthermore, in this embodiment, the stamp part 21 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 parts 21 are in a standby state, they are moved in a direction approaching each other by a command from the control part. At this time, the stamp part 21 is moved and brought into contact with each other in a direction closer to each other than when the coating part of the electric wire 100 is marked. Thereby, each of the stamp portions 21 comes into contact with the exposed portion of the other stamp portion 21 at the exposed portion (particularly, the portion in contact with the wire covering portion), and is difficult to dry at the contacted portion. Therefore, in this embodiment, drying of the ink in the stamp part 21 is prevented.

  The ink used for the marking is an alcohol-based dye ink such as a general stationery ink. More specifically, it is an alcohol-based dye ink having a viscosity of 2.0 mPa · s to 5.0 mPa · s, a dye content of 1% by weight to 10% by weight, and a solid content of 20% by weight or more. . For this reason, it is desirable that the porous material constituting the stamp portion 21 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.

  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.

  Thus, according to the marking device 1 for the electric wire 100 according to the present embodiment, the ink from the ink tank 10 is interposed between the ink tank 10 and the main body portion 20, and the ink from the ink tank 10 is disposed on the stamp portion 21 side in the main body portion 20. Ink is supplied to the stamp portion 21 in the main body portion 20 through the flexible tube 30 without attaching the ink tank 10 itself to the main body portion 20. be able to. For this reason, the main-body part 20 will shrink and it can prevent that an installation space will become excessive. Further, even if vibration is generated by the operation for bringing the stamp portion 21 into contact with the covering portion, the ink tank 10 is not attached to the main body portion 20 itself and is connected through the flexible tube 30. The vibration is difficult to be transmitted to the ink tank 10 and the occurrence of ink supply failure and ink leakage due to the vibration can be suppressed.

  The main body 20 further includes a felt part 22 that absorbs ink sent through the flexible tube 30 and supplies the absorbed ink to the stamp part 21. For this reason, the ink received in the ink tank 10 reaches the felt part 22 through the flexible tube 30 and is guided from the felt part 22 to the stamp part 21. Thereby, it is not necessary to directly attach the flexible tube 30 to the operating member (and the surrounding operation member) called the stamp portion 21, and it is possible to prevent the flexible tube 30 from being detached due to repeated operations.

  In addition, since the leakage ink holding portion 23 that holds ink leaking from the opening portion 22c of the felt portion 22 is further provided, when the ink is excessively supplied to the felt portion 22 and the ink overflows, the ink is The leaked ink holding unit 23 holds the ink. As a result, it is possible to suppress a situation in which the ink is excessively supplied to the stamp portion 21 and an application failure to the wire covering portion occurs.

  Moreover, since the main-body part 20 is further provided with the housing | casing 20a which covers the felt part 22 and the leakage ink holding | maintenance part 23, it can reduce possibility that the ink hold | maintained at these will adhere to a worker etc.

  Further, since the housing 20a has an air hole 20b that allows the outside and the inside to communicate with each other, air reaches the ink tank 10 through the felt portion 22 and the flexible tube 30 from the air hole 20b, and as the ink supply proceeds, the ink It is possible to prevent a situation in which a supply failure occurs due to a decrease in pressure in the tank 10.

  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.

  For example, in the above-described embodiment, the marking device 1 for the electric wire 100 has been described as an example. However, the present invention is not limited to the marking device 1 for the electric wire 100 but is applied to an application device that applies a high viscosity resin such as a primer to the electric wire 100. Alternatively, the present invention may be applied to an application apparatus that applies a high-viscosity coating agent that coats the marking to the electric wire 100.
