[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric wire identification ring mark printing apparatus that applies a ring-shaped mark to a surface of an electric wire in a non-contact manner for the purpose of identifying the type and size of the electric wire of an automobile or the like.
[0002]
[Prior art]
Conventionally, as a kind of printing apparatus that applies this kind of electric wire identification mark in a non-contact manner, in addition to a printing method in which ink is ejected from an ink nozzle by pressure and applied to the surface of the electric wire, centrifugal force due to rotation of the marking drum is applied. There is a printing method in which ink is blown out from the ink blowing holes provided on the outer peripheral surface and applied to the surface of the electric wire.
[0003]
Among these, in the case of manufacturing an electric wire on which a ring-shaped mark is printed using the latter printing method, for example, as shown in FIG. 13, the supply is sequentially fed from the supply reel 1 along a predetermined supply path. The coated wire 2 is guided by a printing device 5 that applies a ring-shaped mark for identifying a downstream electric wire as a coated wire 4 having a coated portion formed by extruding the outer periphery at the position of the extruder 3. The electric wire 4 on which the ring-shaped mark was applied by the printing device 5 was cooled in the cooling tank 6 and then wound around the take-up reel 8 via the take-up device 7 on the downstream side.
[0004]
14 to 16, the printing device 5 is provided in a mark printing case 10 through which the electric wire 4 passes and in the mark printing case 10, and has a predetermined interval on both sides of the electric wire 4 respectively. A pair of marking drums 11, 12 that are misaligned along the supply direction of the electric wires 4, a drive mechanism (not shown) that rotationally drives the marking drums 11, 12, and an ink tank 13 in which marking ink is stored The ink supply mechanism for supplying the ink from the ink tank 13 to the marking drums 11 and 12 through the ink supply pipes 14 and the ink return pipe 15 for returning the ink in the mark printing case 10 to the ink tank 13 are provided.
[0005]
As shown in FIGS. 17 and 18, the marking drums 11 and 12 are provided with a plurality of (six in this embodiment) ink blowing holes on the outer peripheral surface thereof at regular intervals in the circumferential direction. Ink 16 supplied to the inside of the marking drum 11 from each ink blowing hole is blown out by the centrifugal force generated by the rotation of the marking drums 11 and 12, and the outer circumference of the electric wire 4 guided along the supply direction P to the sides thereof. It is configured to be sprayed onto the surface.
[0006]
Then, as shown in FIGS. 15 to 19, a semicircular arc shape is formed on one side surface (left side surface in FIG. 17) of the outer peripheral surface of the electric wire 4 by the ink 16 blown from the marking drum 11 on the upstream side in the supply direction P of the electric wire 4. When the mark 17a is printed and then passes through one side of the marking drum 12 on the downstream side in the supply direction P of the electric wire 4, the other side of the outer peripheral surface of the electric wire 4 by the ink 16 blown from the marking drum 12 (see FIG. 18 is printed on a semicircular mark 17b on the outer peripheral surface of the electric wire 4, and a ring-shaped ring mark 17 (also referred to as a band mark) is printed at predetermined intervals.
[0007]
At this time, the marking drums 11 and 12 are synchronously driven so that the mark 17a and the mark 17b are at the same position on the outer peripheral surface of the electric wire 4.

As shown by the two-dot difference line, the electric wire 4 is configured to pass through the central portions of the shielding cylinders 24 and 25.
[0010]
Then, when the ring mark 17 for identifying the electric wire 4 (FIG. 18) is printed on the outer peripheral surface of the electric wire 4, the inner shielding cylinder 25 is slid by operating the inner shielding cylinder 25 as shown in FIG. When the positioning stopper 26 provided on the contact plate 23 is brought into contact with the end face of the support plate 23, the ink passage slits 24a and 25a are in a ring mark printing posture in which they are in communication with each other.
[0011]
In this ring mark printing posture, the electric wire 4 passing through the sealing cylinder portion 22 has ink 16 blown out from the marking drum 11 by centrifugal force at the position of the marking drum 11 (FIG. 20) as shown in FIG. A semicircular mark 17a (FIG. 17) is printed on one side of the outer peripheral surface of the electric wire 4 after passing through the ink passage slits 24a and 25a (FIG. 21), and then the marking drum on the downstream side in the supply direction P of the electric wire 4 18, the ink 16 blown out by the centrifugal force from the marking drum 12 passes through the ink passage slits 24 a and 25 a (FIG. 21) as shown in FIG. A semi-arc-shaped mark 17b (FIG. 17) is printed on the side, and a ring-shaped ring mark 17 continuous to the outer peripheral surface of the electric wire 4 is printed at predetermined intervals.
[0012]
Next, when producing the electric wire 4 on which the ring mark 17 is not printed on the outer peripheral surface, the inner shielding cylinder 25 is slid to the opposite side of the inner shielding cylinder 25 as shown in FIG. When the positioning stopper 27 provided at the position is brought into contact with the end surface of the support plate 23, the ink passage slits 24a and 25a are displaced from each other, and the ink passage slits 24a of the outer shielding cylinder 24 are moved to the inner shielding cylinder 25. The ink shielding posture is closed with
[0013]
In this ink shielding posture, the electric wire 4 passing through the sealing cylinder portion 22 is at the position of the marking drum 11 (FIG. 20), and the ink 16 blown out by the centrifugal force from the marking drum 11 passes through the ink passage slit 24a. However, it is shielded by the inner inner shielding cylinder 25 in FIG. 22, and the application of the ink 16 to the outer peripheral surface of the electric wire 4 is prevented. Thereafter, also when passing through one side of the marking drum 12 on the downstream side in the supply direction P of the electric wire 4, the ink 16 blown out by the centrifugal force from the marking drum 12 also passes through the ink passage slit 24a. The inner shielding cylinder 25 is shielded to prevent the ink 16 from being applied to the outer peripheral surface of the electric wire 4. Here, the electric wire 4 on which the ring mark 17 is not printed is produced.

Then, as shown in FIG. 12, the third portion 22c, the second portion 22b, and the first portion 22a of the sealing cylindrical body portion 22 are sequentially arranged along the supply direction P of the electric wire 4 to pass the second ink. The slit 33b corresponds to the two-hole type marking drum portion 11D of the first merged marking drum 31 and the first ink passage slit 33a corresponds to the two-hole type marking drum portion 12D of the second merged marking drum 32. Arranged. That is, as shown in FIG. 2, the ink passage slits 33 of the sealing cylinder portion 22 are arranged corresponding to the two-hole type marking drum portions 11 </ b> D and 12 </ b> D of the merged marking drums 31 and 32.
[0056]
Thereafter, both the merged marking drums 31 and 32 are rotated in the same procedure as described above, and the ink 16 supplied to the interior of the merged marking drum 31 by the centrifugal force due to the rotation is two-hole marking drum portion 11D. , 12D are blown from a set 37 of ink blowing holes 35, 36, and the sides thereof are sprayed onto the outer peripheral surface of the electric wire 4 guided along the supply direction P.
[0057]
In addition, when printing is performed with the two-hole type marking drum portions 11D and 12D in this way and then it is desired to switch to the single-hole type marking drum portions 11C and 12C again, the sealing member 21 is rotated in the same procedure as described above. Just rotate it.
[0058]
As described above, the sealing member 21 is detached from the jig mounting groove 20 of the mark printing case 10 by the attaching / detaching operation unit 30 while the merged marking drums 31 and 32 are mounted in the mark printing case 10. The single-hole type marking drum portions 11C and 12C and the two-hole type marking drum portions 11D and 12D can be automatically and quickly formed by simply inserting the sealing member 21 into the jig mounting groove 20 again after being rotated. Can be switched automatically.
[0059]
Here, when replacing the marking drum (FIGS. 23 to 25) itself as in the prior art, the lid 10a of the mark printing case 10 is removed while the printing device 5 is stopped, and the marking drum 11A, While a series of operations such as replacement of 12A, 11B, and 12B is a time loss, this embodiment can significantly reduce the time loss.
[0060]
In addition, a complicated operation such as removing the lid 10a of the mark printing case 10 and replacing the marking drums 11A, 12A, 11B, and 12B is not required, and the single operation is performed by the automatic operation of the attachment / detachment operation unit 30. It is possible to switch between the marking drum portions 11C and 12C and the two-hole type marking drum portions 11D and 12D. Accordingly, it is possible to reduce a great deal of labor for manual work.
[0061]
In addition, in the said embodiment, although the thing of the structure where the outer side shielding cylinder 24 and the inner side shielding cylinder 25 in the sealing cylinder part 22 were made into the cylinder with a non-circular cross section is shown, it is a cylinder with a circular cross section. Even if it exists, what is necessary is just to have the rotation prevention structure which cannot be relatively rotated around the axis.
[0062]
Moreover, although the structure provided with the positioning stoppers 26 and 27 on the inner side shielding cylinder 25 side is shown, the positioning stoppers 26 and 27 for restricting the movement of the inner side shielding cylinder 25 during the sliding operation are shown on the outer side shielding cylinder 24 side. It is good also as a structure provided for.
[0063]
【The invention's effect】
According to the present invention, the sealing member is detached from the mark printing case by the attaching / detaching operation portion in a state where the merged marking drum is mounted in the mark printing case, for example, as in claims 2 and 3. It is possible to automatically switch the marking drum portions having different hole patterns in a short time by simply inserting the sealing member again after being rotated.
[0064]
Therefore, compared to the case where the marking drum itself is replaced, the time loss required for a series of operations such as replacing the marking drum after removing the lid of the mark printing case can be greatly shortened. Moreover, since it is possible to automate the attaching / detaching operation unit, it is possible to greatly reduce a great deal of labor for manual work.
