DESCRIPTION OF EMBODIMENTS
A preferable embodiment according to the present invention is described with reference to drawings . Fig. 1 is an illustration showing an apparatus for coloring electric wire according to an embodiment of the present invention. The apparatus for coloring electric wire 1 is structured with two ink cartridges 10a, 10b, and two ink-print members 20a, 20b.
The ink cartridge 10a, 10b is for holding ink. The ink-print member 20a, 20b is formed by felt or permeable rubber which can receive and hold ink, so that the ink-print member 20a, 20b receives ink supplied from the ink cartridge 10a, 10b, and holds the ink inside it. The ink-print member 20a, 20b is elastically deformed against an object to be contacted so as to print the ink held therein to the object.
The ink-print member 20a, 20b includes an ellipsoidal portion
21a, 21b with an ellipsoidal cross-section, and an ink guiding portion 22a, 22b connecting the ellipsoidal portion with the ink cartridge 10a, 10b. The ink is led through the ink guiding portion 22a, 22b to the ellipsoidal portion 21a, 21b. The ellipsoidal portions 21a, 21b of the ink-print members 20a, 20b are contacted to each other when the ink-print members 20a, 20b are not operated to color electric wire 100.
The ink-print members 20a, 20b are structuredmovable . Physically, the ink-print members 20a, 20b are arranged movable so as to approach and separate from each other (see arrow A) . Thereby, a gap between the ink-print members 20a, 20b is adjustable. The ink-print members 20a, 20b are pivotable around the ink guiding portion 22a, 22b to povit a predetermined angle (see arrow B) . The ink-print members 20a, 20b is further movable up-and-down together with the ink cartridge 10a, 10b (see arrow CI, C2) .
A method of coloring electric wire by the apparatus for coloring 1 according to the embodiment will be described with reference to Figs. 1 and 2. Figs. 2A-2C are cross-sectional views of the electric wire 100 after coloring. In Fig. 2A, the electric wire is colored fully around it. In Fig. 2B, the electric wire 100 is colored one side thereof. In Fig. 2C, the electric wire 100 is colored both sides thereof. The apparatus for coloring 1 can color the electric wire 100 about fully around it, one side and both sides of it.
First, operation for coloring the electric wire 100 fully around it is explained. The two ink-print members 20a, 20b are contacted in an initial condition. For coloring the electric wire 100 fully around it, the two ink-print members 20a, 20b are reciprocated about the electric wire 100 so as to contact the contact portions d with the electric wire 100.
More in detail, the two ink-print members 20a, 20b are moved in a forward direction CI. Then, the ink-print members 20a, 20b are contacted to the electric wire 100. The ink-print members 20a, 20b are furthermore moved to the electric wire 100 after contacting to the electric wire 100. Thereby, the two ink-print members 20a, 20b are pivoted around the ink guiding portions 22a, 22b. Then, the contact portions of the ink-print members 20a, 20b are passed over the electric wire 100. Thereby, the one side of the electric wire 100 is colored.
Thereafter, the two ink-print members 20a, 20b are moved in a backward direction C2. Similarly as the case of moving in the forward direction CI, in the case of moving in the backward direction C2, the remained other side of the electric wire is colored. As mentioned above, the electric wire 100 can be colored fully around it as shown in Fig. 2A (see marking 101) .
Second, operation for coloring the electric wire 100 about one side thereof is explained. The two ink-print members 20a, 20b are contacted to the electric wire 100 without reciprocating the contact portions d of the two ink-print members against the electric wire 100. When the two ink-print members 20a, 20b are contacted to the electric wire 100 without passing the contact portion d over it, the electric wire 100 is colored about the one side thereof, but not about the other side thereof, so that one-side coloring can be acted. Thus, reducing the usage of ink, one-side coloring can be performed as shown Fig. 2B (see marking 103) .
Next, operation for coloring the electric wire 100 about both sides thereof is explained. When coloring the electric wire 100 about the both sides thereof, the two ink-print members 20a, 20b are detached from each other so as to adjust a gap between the two ink-print members 20a, 20b similarly as a diameter of the electric wire 100. The two ink-print members 20a, 20b with the gap as similar as the diameter of the electric wire are reciprocated about the electric wire 100. The gap is adjusted as similar as the diameter of the electric wire, so that the electric wire 100 is colored about both ends with the ink. Thus, both-side coloring can be acted. Therefore, reducing usage of ink, coloring the both sides of the electric wire 100 can be performed as shown Fig. 2C (see marking 102) .
According to the above embodiment, the two ink-printed members with the gap are reciprocated over the electric wire 100. It is not limited, and the two ink-print members 20a, 20b may be only contacted to the electric wire 100. By contacting, the electric wire 100 can be colored at the both sides thereof.
Figs. 3A-3E are illustrations showing examples of the electric wires 100 colored according to the above embodiment. Fig. 3A shows a first example. Fig. 2 shows a second example. Fig. 3C shows a third example. Fig. 3D shows a fourth example. Fig. 3E shows a fifth example.
As shown in Fig. 3A, the electric wire 100 at an end portion is colored fully around coloring 101 fully around it. Circuit information 104 indicating a connecting counterpart, which the electric wire 100 is connected to, is provided at a middle portion of the electric wire by typing. The circuit information 104 is arranged plurally with an even distance for the electric wire having a predetermined length. The circuit information 104 is provided not by the apparatus of coloring 1 according to the embodiment, but by a typing apparatus separated from the apparatus of coloring 1.
According to examples shown in Figs. 3B-3E, a both-side coloring 102 (similar coloring behind side in the illustration) and one-side coloring 103 are provided at the end portion of the electric wire 100. As shown in these examples, the both-side coloring 102 and one-side coloring 103 can be provided together in one electric wire 100.
Figs. 4A-4C are illustrations showing an example of the electric wire 100 colored by the embodiment according to the present invention. Fig. 4A shows a sixth example. Fig. 4B is a first cross-section view of the electric wire in Fig. 4A. Fig. 4C is a second cross-section view of the electric wire in Fig. 4A.
According to the method of coloring by the embodiment, the electric wire 100 can be colored as shown in Figs. 4A-4C, by print positions arranged on the electric wire 100 and printing by the ink-print members 10a, 10b. In other words, near-fully round coloring 105 surrounding the electric wire 100 near-fully can be provided at the end portion of the electric wire 100 as shown- in Figs. 4A and 4B.
By applying the method of coloring both-sides of the electric wire 100, near-both-sides coloring 106 can be provided as shown in Fig. 4C.
According to the method of coloring the electric wire 100 mentioned above in the embodiment, the two ink-print members 10a, 10b are contacted to each other when the electric wire 100 is not colored, so that area of the ink-print members 20a, 20b, which are exposed to air, is reduced in case other than when coloring the electric wire 100. Thus, dry-up of ink is controlled. Thereby, dry-up of ink is prevented and usage of ink can be reduced.
The electric wire 100 is colored also by reciprocating the electric wire 100 through a gap between the two ink-print members 20a, 20b so as to push contact areas d of the two ink-print members 20a, 20b to expand the contact areas d which contact with the electric wire 100. For that, first, when the two ink-print members 20a, 20b are moved in the forward direction CI, the one side of the electric wire • 100 is colored. When the electric wire 100 is moved in the backward direction, the other side thereof is colored. Thereby, the ink is effectively transferred to the electric wire 100 when coloring the electric wire fully around it. Therefore, usage of ink can be reduced.
The electric wire 100 is colored also by contacting the two ink-print members 20a, 20b to the electric wire 100 without passing the electric wire 100 through the contact areas d of the two ink-print members 20a, 20b. Just at the moment when the ink-print member is contacted to the electric wire without passing the electric wire 100 through the contact areas d, the one side of the electric wire 100 is colored. Thereby, the one side of the electric wire 100 can be colored so as to simultaneously reduce the usage of ink.
The electric wire 100 is colored also by reciprocating the ink-print members 20a, 20b against the electric wire 100 through a gap between the two ink-print members 20a, 20b, which are detached from each other to make the gap equal to a diameter of the electric wire 100, so as to contact the electric wire 100 to the two ink-print members 20a, 20b. When the two ink-print members 20a, 20b are detached from each other to make the gap equal to the diameter of the electric wire and the electric wire 100 is reciprocated through the gap between the two ink-print members 20a, 20b so as to contact the electric wire 100 to the two ink-print members 20a, 20b, only the both end sides of the electric wire is colored, so that both-side coloring can be acted. Thereby, the both-side of the electric wire 100 can be colored so as to simultaneously reduce the usage of ink.
Next, the second embodiment according to the present invention is described. Fig .5 is an illustration showing an apparatus for coloring 2 according to the second embodiment. The apparatus of coloring 2 includes a plurality of ink cartridges 30, a plurality of coloring heads 40, a plurality of covers 50, a plurality of pillars 61, 62 and a movable plate 70. The plurality of ink cartridges 30 is for holding ink, and each ink cartridge holds different color ink from each other. The plurality of coloring heads 40 is for coloring the electric wire 100 with ink supplied from each ink cartridge 30.
The plurality of covers 50 is arranged at a top of each of the plurality of ink cartridges 30 for covering. Each cover 50 includes a through hole 51, through which the ink can be flown into the cartridge 30. The cover 50 is formed into an L-shape, and provided at one side of L shape with through holes 52, which each of the two pillars 61, 62 pass through.
The cover 50 can move up-and-down along the two pillars 61, 62. Thereby, the coloring head 40, which is connected through the ink cartridge 30 to the cover 50, also moves up-and-down. In the apparatus of coloring 2, the electric wire 100 is arranged under the coloring head 40, and colored by operation of moving the coloring head 40 up-and-down .
Low ends of the plurality of pillars 61, 62 are fixed at the movable plate 70. The movable plate 70 can move along a lengthwise direction of the electric wire 100. Thereby, a coloring point at the electric wire 100 can be adjusted.
Fig. 6 is a front view showing the detail of the coloring head 40 shown in Fig. 5. The coloring head 40 includes a base body 41, a leg body 42, and two ink-print members 43a, 43b.
The base body 41 is a connecting member to be connected to a bottom of the ink cartridge 30. The leg body 42 is a member extending from the base body downwardly. The leg body 42 in a front view includes two straight portions 42a extending downwardly and proj ecting portions 42b extending at top ends of the straight portions 42a toward each opposite straight portion 42a. The two ink-print members 43a, 43b are enveloped within the projecting portions 42b so as to be arranged oppositely to each other. The projecting portions 42b are contacted to each other, and provided with a openings 42c at the contact areas of the projecting portions 42b. The ink-print members 43a, 43b are contacted to each other. Thereby, the leg portion 42 functions as an enclosure for the two ink-print members 43a, 43b.
The coloring head 40 is provided with an ink guiding passage 44 extending from the base body 41 through leg portion 42 to the two ink-print members 43a, 43b. The ink from the ink cartridge 30 is guided through the ink guiding passage 44 to the ink-print members 43a, 43b.
The leg portion 42 is provided with a cut-out 45. The leg portion 42 having the cut-out 45 can bend so as to detach the two ink-print members 43a, 43b from each other.
The method for coloring the electric wire 100 by the apparatus of coloring 2 according to the second embodiment is described with reference to Figs. 5, 6 and 2.
According to the method for coloring by the second embodiment, the electric wire 100 is colored by contacting the ink-print members 43a, 43b to the electric wire 100 as similar as the first embodiment. The plurality of ink cartridges 30 includes respectively different color ink from each other, as mentioned with reference to Fig. 4. Therefore, plural sets of the two ink-print members 43a, 43b are arranged for each different color.
The electric wire 100 is arranged under the plurality of coloring heads 40, and the apparatus for coloring 2 selects any one from among the plurality of ink cartridges 30 (in other words, the plural sets of two ink-print members 43a, 43b) accordingly to required color. The selected ink-cartridge 30 is moved down so as to color the electric wire 100.
The apparatus of coloring 2 according to the second embodiment can color the electric wire 100 fully around it.
Operation of the apparatus of coloring will be described in detail .
The two ink-print members 43a, 43b are moved in the forward direction CI so as to pass the contact portion of the projecting portions 42b over the electric wire 100. Thereby, after the projecting portions 42b contact the electric wire 100, the leg portion 42 is bent so as to detach the two ink-print members 43a, 43b from each other. Thus, the contact portions of the projecting portions 42b pass over the electric wire 100.
Thereafter, the two ink-print members 43a, 43b are moved in the backward direction C2. By the above operations, the electric wire can be colored fully around it as shown in Fig. 2A.
According to the second embodiment, the two ink-print members 43a, 43b are covered by the projecting portions 42b. It is not limited, and the ink-print members 43a, 43b may not be fully covered (especially lower surface) . If the lower surface of the ink-print member is not covered, one side coloring of the electric wire 100 can be acted.
The electric wire 100 is contacted to the two ink-print members 43a, 43b without reciprocating the contact areas of the two ink-print members 43a, 43b about the electric wire 100. When the ink-print members 43a, 43b are contacted to the electric wire 100 without passing over the electric wire, the one side of the electric wire 100 is colored, and the other side thereof is not colored. Thus, one side coloring is acted. Thereby, the one-side surface of the electric wire can be colored so as to simultaneously reduce the usage of ink as shown in Fig. 2B.
According to the method of coloring electric wire 100 by the second embodiment, dry-up of ink can be prevented and the usage of ink can be reduced as same as the first embodiment. When the electric wire 100 is colored fully around it, ink can be printed efficiently.
According to the second embodiment , the any one set of two ink-print members 43a, 43b is selected from among the plural sets of two ink-print members 43a, 43b accordingly to the required color, and the electric wire 100 is colored. Therefore, changing the color to be colored can be adapted rapidly, so that coloring efficiency can be improved.
Next, the third embodiment according to the present invention is described. Fig .7 is an illustration showing an apparatus for coloring 3 according to the third embodiment. The apparatus of coloring 3 according to the third embodiment includes two ink-print members 80a, 80b and two receiving sections 90a, 90b.
The two ink-print members 80a, 80b are the same as that of the first embodiment and the second embodiment . The two receiving sections 90a, 90b are U-shape sections, each section receiving the ink-print member 80a, 80b respectively. The ink-print member 80a, 80b is fitted in the U-shape of the receiving section.
The receiving sections 90a, 90b are arrangedmovably. The receiving sections 20a, 20b are arranged so as to position each opening 21a, 21b corresponding to each other at a standby position E. Thereby, the ink-print members 10a, 10b at the standby position are prevented from dry-up of ink.
The receiving sections 90a, 90b are departing from each other and moving downwardly. The receiving sections 90a, 90b moves to a middle position F. Furthermore, the receiving sections 90a, 90b move through the middle position F downwardly and simultaneously approach each other. Then, the receiving sections 90a, 90b can move to the final position G.
The method for coloring the electric wire 100 by the apparatus of coloring 3 according to the third embodiment is described with reference to Figs. 7 and 2. The apparatus of coloring 3 according to the third embodiment can color fully around the electric wire 100, or one side thereof, or both sides thereof.
Operation for coloring the electric wire 100 fully around is described here. By clamping the electric wire 100 between the two ink-print members 80a, 80b, the electric wire 100 is colored fully around it. More physically, in a condition that the electric wire
100 is arranged at a predetermined position, the two receiving sections
90a and 90b are moved. The two receiving sections 90a, 90b are moved through the middle position F to the final position G. At the final position G, the two ink-print members 80a, 80b contact each other, so that the electric wire 100 is colored fully around it as shown in Fig. 2A.
At the final position, the two ink-print members 80a, 80b may clamp the electric wire 100 with a gap therebetween to be smaller than the diameter of the electric wire 100. In short, for coloring the electric wire 100 fully around, the gap between the two ink-print members 80a, 80b at the final position G may be smaller than the diameter of the electric wire 100.
Next, operation for coloring one side of the electric wire 100 is described here. The one side of the electric wire 100 can be colored by contacting only one of the two ink-print members 80a, 80b to the electric wire 100. More physically, the only one of the two receiving sections 90a, 90b is moved and the other one is remained at the standby position E. The one of the receiving sections 90a, 90b is moved through the middle position F to the final position G. Thereby, the one side coloring can be acted as shown in Fig. 2B.
Furthermore, operation for coloring both sides of the electric wire 100 is described here. The both sides of the electric wire 100 can be colored by clamping the electric wire 100 in a gap between the two ink-print members 80a, 80b which are detached with a distance as similar as the diameter of the electric wire 100. More physically, both of the two receiving sections 90a, 90b are moved to a vicinity of the final position G (that is, a position in which the two ink-print members 80a, 80b do not contact to have a small gap) . At the position, a distance between the two ink-print members 80a, 80b becomes similar as the diameter of the electric wire 100. Thereby, the both sides coloring can be acted as shown in Fig. 2C.
According to the method of coloring electric wire 100 by the third embodiment, dry-up of ink can be prevented and the usage of ink can be reduced as same as the first embodiment.
Furthermore, according to the third embodiment, the electric wire
100 is colored by clamping the electric wire 100 with the two ink-print members 80a, 80b. Thus, by clamping the electric wire 100 between the two ink-print members 80a, 80b, the both sides of the electric wire 100 is colored simultaneously from both sides, fully around it. Thus, for coloring the electric wire 100 fully around it, ink is printed efficiently and usage of ink can be reduced.
The electric wire 100 is colored by clamping the electric wire 100 in the gap between the ink-print members 80a, 80b to be separated as similar as the diameter of the electric wire 100. Thereby, only both sides of the electric wire 100 are colored, so that both-sides coloring can be acted. Therefore, the both-sides of the electric wire can be colored so as to simultaneously reduce the usage of ink.
The electric wire 100 is colored by contacting the only one of the two ink-print members 80a, 80b to the electric wire 100. Thereby, only one side of the electric wire 100 is colored, so that the one-side coloring can be acted. Therefore, the one-side of the electric wire can be colored so as to simultaneously reduce the usage of ink.
A first preferable example will be described here. Fig. 8 is an illustration showing an apparatus of coloring 4 according to the first example. The apparatus of coloring shown in Fig. 8 is similar as that of the first embodiment, other than a part. The same components structured in Fig. 1 are marked by the same reference and description for that is omitted.
According to an apparatus of coloring 4 shown in Fig. 8, the two ink-print members 20a, 20b at an initial condition are not contacted and detached from each other with a space h. The electric wire 100 is colored from the both side thereof by the two ink-print members 20a, 20b.
A method of coloring by the apparatus of coloring 4 according to the first preferable example is described with reference to Figs. 8 and 2. According to the apparatus of coloring 4, the electric wire 100 can be colored fully around it, about one-side or the both side thereof .
Operation of coloring the electric wire 100 fully around it is described here. For coloring the electric wire 100 fully around it, the gap h between the two ink-print members 20a, 20b is adjusted to be smaller, than the diameter of the electric wire 100. The gap h may be zero. The two ink-print member 20a, 20b are reciprocated to pass the electric wire 100 through the gap h.
Describing in detail, the two ink-print members 20a, 20b are moved in the forward direction CI so as to pass the electric wire 100 through the gap h. Thereby, the one side of the electric wire 100 is colored. When passing the electric wire 100 through the gap h, just at the moment when the two ink-print members 20a, 20b abut on the electric wire 100, the two ink-print members 20a, 20b pivot around the ink guiding portions 22a, 22b. Therefore, the gap h is expanded and the electric wire 100 passes through the gap h so as to color the one side of the electric wire 100.
After that, when the two ink-print members 20a, 20b are moved in the backward direction C2, the remained other side of the electric wire 100 is colored as similar as the case of moving in the forward direction CI. Thus, the electric wire 100 can be colored fully around it as shown in Fig. 2A (see reference mark 101) .
As mentioned above, coloring is by the ink-print members 20a, 20b and not by spraying with a spray nozzle, so that usage of ink, which corresponds only to printing by contacting with the ink-print members 20a, 20b, is used. When coloring the electric wire 100 fully around it, the electric wire 100 is colored from both sides by the ink-print members 20a, 20b, so that any action such as swinging a nozzle is not required, and the electric wire 100 can be colored efficiently with ink.
Various methods of coloring, in which ink is sprayed from a nozzle for coloring to electric wire (Japan Patent Application Publication No. H06-190341, Japan Patent Application Publication No . 2008-93617, Japan Patent Application Publication No. 2004-15721) have been proposed. According to such usual method of coloring, coloring by spraying ink generates useless ink not to contact to electric wire during spraying. Thereby, usage of ink is increased. When coloring the electric wire 100 fully around it, the spray nozzle spraying is required to swing. During swing, amount of useless ink not to contact to the electric wire is increased, so that usage of ink is more increased.
Oppositely, according to the method of coloring the electric wire 100 of the first preferable example, the ink-print members 20a, 20b are used and action of nozzle swing is not required. Thereby, ink is printed efficiently to the electric wire 100, so that usage of ink can be reduced.
Operation of coloring the one side of the electric wire 100 is described herein. For coloring the one side of the electric wire 100, the space h between the two ink-print members 20a, 20b should be adjusted so as to be smaller than the diameter of the electric wire 100. The space h can be zero.
Thereafter, the two ink-print members 20a, 20b are contacted to the electric wire 100 without reciprocating the space h against the electric wire 100. When the two ink-print members 20a, 20b are contacted to the electric wire 100 without passing the space h over it, the electric wire 100 is colored about the one side thereof, but not about the other side thereof, so that one-side coloring can be acted. Thus, reducing the usage of ink, one-side coloring can be performed as shown Fig. 2B (see marking 103) .
Next, operation for coloring the electric wire 100 about both sides thereof is explained. When coloring the electric wire 100 about the both sides thereof, the space h between the two ink-print members 20a, 20b are adjusted similarly as the diameter of the electric wire 100. The two ink-print members 20a, 20b with the space h as similar as the diameter of the electric wire are reciprocated about the electric wire 100. The space h is adjusted as similar as the diameter of the electric wire, so that the electric wire 100 is colored about both ends with the ink. Thus, both-side coloring can be acted. Therefore, reducing usage of ink, coloring the both sides of the electric wire 100 can be performed as shown Fig. 2C (see marking 102) .
According to the above embodiment, the two ink-printed members with the space h are reciprocated over the electric wire 100. It is not limited, and the two ink-print members 20a, 20b may be only contacted to the electric wire 100. By contacting, the electric wire 100 can be colored at the both sides thereof.
According to the method of coloring by the first preferable example, the electric wire 100 is colored by storing ink in the two ink-print members 20a, 20b, which sponge the ink and are elastically deformed by contacting an object, and contacting the two ink-print members 20a, 20b on the electric wire 100 from the both side thereof . Therefore, spraying by a spray nozzle is not required, so that usage of ink, which corresponds only to printing by contacting with the ink-print members 20a, 20b, is used. The electric wire 100 is colored from the both sides thereof, so that when coloring the electric wire fully around it, any action such as swinging a nozzle is not required. Thereby, the usage of ink can be reduced.
The electric wire 100 is colored by reciprocating the two ink-print members 20a, 20b, which are arranged to have the space h smaller than the diameter of the electric wire 100, about the electric wire 100 so as to pass the electric wire 100 through the space h. Thereby, when the two ink-print members 20a, 20b with the space d are moved in the forward direction CI, the one side of the electric wire 100 is colored. When the two ink-print members 20a, 20b is moved in the backward direction, the remained other side of the electric wire 100 is colored. Thereby, the ink is effectively transferred to the electric wire 100 when coloring the electric wire fully around it. Therefore, usage of ink can be reduced.
The electric wire 100 is colored also by contacting the two ink-print members 20a, 20b to the electric wire 100 without passing the electric wire 100 through the space d of the two ink-print members 20a, 20b. Just at the moment when the ink-print member is contacted to the electric wire 100 without passing the electric wire 100 through the space d, the one side of the electric wire 100 is colored. Thereby, the one side of the electric wire 100 can be colored so as to simultaneously reduce the usage of ink.
The electric wire 100 is colored also by reciprocating the two ink-print members 20a, 20b against the electric wire 100 through a space d between the two ink-print members 20a, 20b, which are detached from each other to make the space equal to a diameter of the electric wire 100, so as to contact the electric wire 100 to the two ink-print members 20a, 20b. When the two ink-print members 20a, 20b are detached from each other to make the space d equal to the diameter of the electric wire 100 and the ink-print members 20a, 20b having the space d are reciprocated about the electric wire 100 so as to contact the electric wire 100 to the two ink-print members 20a, 20b, only the both sides of the electric wire 100 is colored, so that both-side coloring can be acted. Thereby, the both-side of the electric wire 100 can be colored so as to simultaneously reduce the usage of ink.
The second preferable example is described here. Fig. 9 is an illustration showing a coloring head 40 for coloring the electric wire 100. The coloring head 40 as shown in Fig. 9 is the same as that of the second embodiment, other than a part. The same components structured in Fig. 6 are marked by the same reference and description for that is omitted.
According to the coloring head 40 shown in Fig.9, the two ink-print members 43a, 43b at an initial condition are not contacted and detached from each other with a space h. The electric wire 100 is colored from the both side thereof by the two ink-print members 20a, 20b.
Describing physically, the leg 42 is a member extending from the base body 41 downwardly. The leg 42 in a front view is formed into a up-side-down U-shape, and the two ink-print members 43a, 43b are provided oppositely to each other inside the U-shape.
The method for coloring the electric wire 100 by the apparatus of coloring 2 according to the second example is describedwith reference to Figs. 9, 5 and 2.
According to the method of coloring of the second example, as same as the first example, the electric wire 100 is colored by contacting the ink-print members 43a, 43b to the electric wire 100. As mentioned above with reference to Fig. 5, the plurality of ink cartridges 30 holds respectively different color. Thereby, plural sets of the two ink-print members 43a, 43b are provided for each colors.
The electric wire 100 is arranged under the plurality of coloring heads 40, after that the apparatus of coloring 2 selects any one from among the plurality of ink cartridges 30 (that is the plural sets of the two ink-print members 43a, 43b). Then, the selected ink cartridge 30 is moved downwardly and the electric wire 100 is colored.
According to the apparatus of coloring 2, the electric wire 100 can be colored fully around it, and one side thereof. Operation for coloring the electric wire 100 fully around it will be described. The two ink-print members 43a, 43b are moved so as to pass the electric wire 100 through the space h.
Describing in detail, the two ink-print members 43a, 43b are moved in the forward direction CI so as to pass the electric wire 100 through the space h. Thereby, the electric wire 100 is colored about one side thereof. By passing the electric wire 100 through the space h, the electric wire 100 contacts to two ink-print members 43a, 43b and the leg 42 is bent so as to separate the two ink-print members 43a, 43b to each other. Therefore, the space h is expanded and the electric wire 100 passes through the space h so as to color the one side of the electric wire 100.
Thereafter, the two ink-print members 43a, 43b are moved in the backward direction C2, so that the remained other side of the electric wire 100 is colored as same as the operation in the forward direction CI. Thus, the electric wire 100 is colored fully around it.
Operation for coloring the one side of the electric wire 100 is described. When coloring the one side of the electric wire 100, the two ink-print members 43a, 43b are moved so as to contact to the electric wire 100 without reciprocating the two ink-print members 43a, 43b about the electric wire 100. Thus, the two ink-print members 43a, 43b are contacted to the electric wire 100 without passing the electric wire 100 through the space h. The electric wire 100 is colored about one side thereof but not colored about the remained other side, so that one-side coloring is acted. Thereby, the one-side of the electric wire 100 can be colored so as to simultaneously reduce the usage of ink as shown in Fig. 2B.
According to the method of coloring by the second example, reducing the usage of ink as same as the first example, the electric wire 100 can be colored efficiently fully around it and also about one side thereof .
According to the second embodiment, the electric wire 100 is colored by selecting any one set corresponding to the color required to color the electric wire 100 from among the plural sets of two ink-print members 43a, 43b arranged for each color. Thereby, changing color to be operated can be corresponded rapidly, and efficiency of coloring can be improved.
The present inventions are described based in the embodiments as mentioned above, but the present invention is not limited in above embodiments. Various change and modifications can be made with the scope of the present invention.
According to the first embodiment and the first example, the ink-print member 20a, 20b is structured with the ellipsoidal portion 21a, 21b, and the ink guiding portion 22a, 22b, and pivoted around the ink guiding portion 22a, 22b during coloring operation. The ink guiding portion 22a, 22b may leak ink unexpectedly during pivoting. Therefore, a cover mat be provided at the ink guiding portion 22a, 22b for preventing leak of ink. In the above embodiment, a color of a cover of the electric wire 100 is preferably unified with white or natural color of covering resin. Additionally, it is preferable that kind of resin is determined corresponding to kind of material of conductor of the electric wire 100 (for example, copper (soft copper, pure copper or hard copper) or aluminum) for recognizing the kind of the conductor material with reference to the color of the cover. Thereby, the conductor material can be judged by the color of cover.
