Description

  The present invention relates to a coating apparatus.

  2. Description of the Related Art Conventionally, an electric wire marking device that performs marking by coloring (applying) ink on a covering portion of an electric wire in order to identify the purpose of use of the electric wire is known as one of the application devices. As such an electric wire marking device, an apparatus has been proposed in which ink is sprayed toward a wire from a plurality of colored nozzles arranged toward the fed wire (see, for example, Patent Document 1). An apparatus has also been proposed that performs marking by spraying ink from one colored nozzle onto an electric wire (see, for example, Patent Documents 2 and 3).

  However, in the marking devices described in Patent Documents 1 to 3, since ink is sprayed from the nozzles, in-cross due to ink that does not color the wire is generated.

  In view of this, there has been proposed a marking device including a porous member that applies ink to a covering portion by contacting the covering portion of the electric wire while holding the ink (see Patent Document 4). In this marking device, the ink is applied to the covering portion as much as the porous member comes into contact with the covering portion, and it is possible to suppress in-cross due to the ink not coloring the electric wire.

JP 2008-93617 A JP-A-6-190341 International Publication No. 2004/015721 JP 2012-252942 A

  In the marking device described in Patent Literature 4, the contact surface side of the porous member is slightly exposed out of the surface (side surface) substantially orthogonal to the contact surface with the electric wire. Here, since the porous member is a soft member, the porous member slips on the electric wire during coloring, or a settling (deformation caused by multiple times of coloring) occurs. Therefore, in the conventional marking apparatus, the coating is performed by baking the exposed portion of the side surface. This coating increases the rigidity of the side surface, and can prevent slipping and settling.

  However, in the conventional marking apparatus, it is necessary to coat the exposed portion, and a complicated operation occurs. This problem is not limited to a marking device that colors ink on an electric wire, but is a problem common to other coating devices. 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 to solve such a conventional problem, and an object of the present invention is to apply a coating apparatus capable of preventing slipping and settling without causing troublesome work. Is to provide.

  The coating device of the present invention is a coating device for applying a liquid agent to a coating portion of an electric wire, and is applied to the coating portion of the electric wire while holding a liquid agent tank that receives the liquid agent and a liquid agent fed from the liquid agent tank. A porous member that applies a liquid agent to the covering portion by contact, and a cover that covers a side surface of the porous member that is substantially orthogonal to the contact surface with the electric wire, and the cover includes the porous member. A substantially semicircular concave portion is formed on the contact surface side, and the liquid member is applied to the covering portion by bringing the concave portion into contact with the electric wire by performing an operation of fitting the concave portion into the electric wire. .

  According to this coating apparatus, the side surface of the porous member is covered with the cover, and the cover portion in contact with the side surface can provide the same effect as when the side surface is coated to increase rigidity, and the coating is complicated. It is possible to prevent slipping and settling without causing work. In addition, since the cover has a recess, it is possible to prevent the porous member from coming into contact with the electric wire as in the case where the cover is not formed with a recess. The wires can also be colored. Further, by adjusting the depth of the concave portion, it is possible to deal with a thick wire.

  According to the present invention, slipping and settling can be prevented without complicated operations.

  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 (liquid agent tank) 10 and a main body portion 20. ing.

  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, ink can be added by removing a lid member (a member also used as a pressurizing mechanism 11 described later) on the large diameter opening portion 10a side. It has become. 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 ink tank 10 includes a pressurizing mechanism 11. The pressurizing mechanism 11 is a plunger that can move, for example, from the large-diameter opening portion 10a side to the small-diameter opening portion 10b side of the ink tank 10, and the plunger moves inside the ink tank 10 by moving to the small-diameter opening portion 10b side. Will be pressurized. As a result, the pressurizing mechanism 11 sends ink from the ink tank 10 to a stamp unit 21 described later.

  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. The two stamp portions 21 are illustrated as being separated from each other in the cross section shown in FIG. 1, but in actuality, the stamp portion 21 has a U-shaped shape or a concave-shaped shape that is lateral to the drawing depth side. Are united. 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. Insufficient supply is unlikely 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 part 20 of the marking device 1 according to the present embodiment includes a felt part 22, a leaked ink holding part 23, and a casing 20a that covers them.

  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.

  Furthermore, in this embodiment, the marking device 1 includes a cover 24 as shown in FIG. The cover 24 covers the side surface of the stamp portion 21 that is substantially orthogonal to the contact surface with the electric wire 100, and is also used as the housing 20a in this embodiment.

  In the marking device 1 according to the present embodiment, the stamp unit 21 and the cover 24 are as follows. FIG. 3 is a schematic view showing the periphery of the stamp portion 21 according to the present embodiment, where (a) shows the stamp portion 21 and the cover 24, and (b) shows the relationship with the electric wire 100. In FIG. 3, only the upper stamp portion 21 and the cover 24 among the upper and lower stamp portions 21 and the cover 24 are shown, but the lower stamp portion 21 and the cover 24 have the same configuration.

  As shown in FIG. 3A, the cover 24 has a substantially semicircular recess 24 a formed on the contact surface side of the stamp portion 21 with the electric wire 100. For this reason, the cover 24 exposes only the contact surface 21a with the electric wire 100 in the stamp portion 21 and the corresponding portion of the recess 24a to the outside, and covers the entire remaining portion. And as shown in FIG.3 (b), the electric wire 100 will be supplied along the recessed part 24a of the cover 24 (depth direction in Fig.3 (a)). For this reason, as will be described later with reference to FIG. 4, the marking device 1 according to the present embodiment operates so as to fit the recess 24 a into the electric wire 100, thereby bringing the stamp portion 21 into contact with the electric wire 100 and serving as a covering portion. A liquid agent will be applied.

  Since it is configured in this manner, even if the side surface of the stamp portion 21 is covered with the cover 24, a situation in which the stamp portion 21 cannot contact the electric wire 100 can be prevented. Further, the electric wire 100 having a small diameter can be colored by the concave portion 24a, and by adjusting the depth of the concave portion 24a, it is possible to cope with an electric wire having a large diameter.

  Next, the operation of the marking device 1 will be described. FIG. 4 is an operation diagram of the marking device 1 and shows a device state 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. 4), 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.

  In addition, since the cover 24 includes the recess 24a, the stamp portion 21 does not come into contact with the electric wire 100.

  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. 5 is an operation diagram of the marking device 1 and shows the device state in the standby state. As shown in FIG. 5, when the two stamp units 21 are in a standby state, they are moved in a direction approaching each other according to a command from the control unit. 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 stamp part 21 will contact contact surfaces 21a, and it becomes difficult to dry. Therefore, in this embodiment, drying in the stamp part 21 is suppressed.

  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 and a solid content of 10% by weight to 20% by weight. 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. 6 is a comparison diagram between the marking device 1 according to the present embodiment and a conventional product. In the description of FIG. 6, the conventional product is a type in which both the contact surface and the side surface of the stamp portion 21 are exposed, and the contact surfaces of the stamp portion 21 are in contact with each other during standby, but the side surface is Exposed. In the conventional product, the side surface of the stamp portion 21 is not coated.

  First, in the marking device 1 according to the present embodiment, the side surface of the stamp portion 21 is covered with the cover 24. For this reason, a design can be accurately formed without being deformed so that the side surface of the stamp portion 21 (excluding the corresponding portion of the recess 24a) is widened during coloring, and the design width is 1.62-1. It is 98 mm. On the other hand, in the conventional product, since the side surface is not covered with the cover 24, the stamp portion 21 is deformed so that the side surface is widened during coloring, and the design width is 1.95 to 2.4 mm. Therefore, it was confirmed that the marking device 1 according to the present embodiment can reduce the target design width.

  More specifically, in the conventional product, the target design width was 2.5 ± 0.5 mm. However, as shown in FIG. 6, a design having a design width outside this range (for example, a design width of 1.95 mm) was formed. On the other hand, when the marking device 1 according to the present embodiment has a target design width of 1.5 ± 0.5 mm, a design having a design width outside the range is not formed, and an accurate design is formed. I can say that.

  Further, in the marking device 1 according to the present embodiment, the side surface of the stamp portion 21 is covered with the cover 24, so that it is more resistant to drying than the conventional product. For example, when the marking device 1 according to the present embodiment is left for 8.5 hours in a temperature environment of 10 ° C., if the device 1 is then operated to perform coloring, a design can be formed, but there is no blur or chipping. It occurred and a proper design could not be formed. Therefore, a proper design was formed by applying pressure twice in succession and supplying ink. On the other hand, in the conventional product, drying occurred from the side surface of the stamp part 21, and even if ink was supplied by pressurization, a stable design could not be formed, and the design became unstable for a long time.

  Similarly, when the marking device 1 according to the present embodiment is allowed to stand for 60 hours in a temperature environment of 10 ° C., a design can be formed, but blurring or chipping occurs, and an appropriate design cannot be formed. Therefore, an appropriate design was formed by applying pressure ten times continuously and supplying ink. On the other hand, in the conventional product, since the stamp part 21 is once dried, a stable design cannot be formed even if ink is supplied by pressurization, and the design becomes unstable for a long time. .

  Furthermore, when the marking device 1 according to the present embodiment is left in a temperature environment of 24 ° C. for 8.5 hours and in a temperature environment of 40 ° C. for 8.5 hours, the device 1 is subsequently operated. When trying to color, the design can be formed, but fading and chipping occurred, and an appropriate design could not be formed. Therefore, a proper design was formed by applying pressure twice in succession and supplying ink. On the other hand, with conventional products, designs can be formed, but fading and chipping occur, and appropriate designs cannot be formed. Proper designs are formed by applying pressure and supplying ink five times in succession. It was. Therefore, it took a relatively long time to form an appropriate design.

  In addition, when the marking device 1 according to the present embodiment is left for 60 hours in a temperature environment of 24 ° C. and when it is left for 60 hours in a temperature environment of 40 ° C., the device 1 is then operated and colored. However, it was possible to form a design, but blurring and chipping occurred, and an appropriate design could not be formed. Therefore, a proper design was formed by applying pressure twice in succession and supplying ink. On the other hand, in the conventional product, since the stamp part 21 is once dried, a stable design cannot be formed even if ink is supplied by pressurization, and the design becomes unstable for a long time. .

  From the above, it has been found that the marking device 1 according to the present embodiment realizes a stable return in return from the standby time as compared with the conventional product.

  In addition, as shown in the coating environment for each temperature, if the conventional product is applied in a temperature environment of 10 ° C, the design width becomes too narrow, and the coating is performed in a temperature environment of 24 ° C and 40 ° C. Then, the design width becomes unstable and splashes are generated. If you try to color with a stamp without attaching the cover 24 with an uncoated sponge, the sponge hangs or slips on the wire 100, which reduces the occurrence of splashes and unstable design width. Arise. In particular, when splashes are generated, the facilities are contaminated by the splashes and the operator is contaminated. On the other hand, in the marking device 1 according to the present embodiment, the side of the stamp portion 21 is covered with the cover 24, so that the stamp portion 21 can be prevented from slipping or splashing on the electric wire. It is possible to prevent the situation where the water gets dirty.

  FIG. 7 is a diagram showing the electric wire 100 marked by the marking device 1 according to the present embodiment. According to the present embodiment, the color of the circuit 100 (ie, the type of the electric wire) can be recognized on the covering portion of the electric wire 100, or the circuit to be inserted later into the connector, etc. Or marking patterns. For example, as shown in FIG. 7, coloring 101 over the entire circumference can be applied to the terminal portion of the electric wire 100.

  Here, the marking device 1 according to the present embodiment uses a porous member that is softer than the conventional product for the stamp portion 21. Thus, the design is easily circulated around the entire circumference of the electric wire 100, and the coloring 101 over the entire circumference is more easily formed.

  In other steps, the circuit information 12 may be given by marking characters on the middle portion of the electric wire 100.

  Thus, according to the marking device 1 according to the present embodiment, the side surface of the stamp portion 21 is covered with the cover 24, and is equivalent to when the side surface is coated with the cover portion in contact with the side surface to increase rigidity. The effect can be obtained, and slipping and settling can be prevented without generating a complicated operation of coating.

  In addition, as described with reference to FIG. 6, the side surface of the stamp portion 21 is covered with the cover 24, so that it is possible to provide the marking device 1 that is resistant to drying and hardly generates splashes.

  In addition, conventionally, when left at a low temperature for a long time, the ink scraps scraped by the plunger attached to the side surface of the syringe are accumulated and solidified, and there is a situation in which the ink is not supplied. As a result, such poor ink supply is prevented.

  Further, since the cover 24 has the recess 24a, it is possible to prevent the stamp portion 21 from being unable to contact the electric wire 100 as when the cover 24 is not formed with the recess 24a. Furthermore, a thin diameter electric wire can also be colored. Further, by adjusting the depth of the concave portion 24a, it is possible to deal with a thick-diameter electric wire.

  In addition, since the flexible tube 30 is interposed between the ink tank 10 and the main body portion 20 and has flexibility to guide the ink from the ink tank 10 to the stamp portion 21 side in the main body portion 20, the ink Ink can be supplied to the stamp portion 21 in the main body portion 20 through the flexible tube 30 without attaching the tank 10 itself to the main body portion 20. For this reason, the main-body part 20 will shrink and it can prevent that the installation space of the marking apparatus 1 becomes 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 the liquid agent that leaks from the opening 22c of the felt portion 22 is further provided, when excessive supply of ink occurs to the felt portion 22 and the liquid agent 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 the 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.

  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 said embodiment, although the marking apparatus 1 of the electric wire 100 was demonstrated to the example, this invention may be applied not only to the marking apparatus 1 of the electric wire 100 but the application apparatus which apply | coats a primer to the electric wire 100, You may apply to the coating device etc. which apply | coat the coating agent which coats marking to the electric wire 100.
