As shown in FIG. 1 , the marking portion 200 side of the hardening portion 300 is defined as the front side, and the hardening portion 300 side of the marking portion 200 is defined as the rear side. That is, the X-axis direction may be a front-back direction, the Y-axis direction may be a left-right direction, and the Z-axis direction may be a vertical direction.

1 to 3, the cable coating printing system 10 includes a guide unit 100, a marking unit 200, a hardening unit 300, an encoder unit 400, a support unit 500, and a control unit (not shown). ) may be included.

The guide unit 100 may support the cable sheath C extruded from an extruder (not shown).

The guide unit 100 may include a first guide unit 110 and a second guide unit 120 .

The first guide part 110 and the second guide part 120 may be spaced apart from each other along the moving direction of the cable sheath C. For example, the first guide part 110 may be disposed in front of the marking part 200 and the second guide part 120 may be disposed in front of the hardening part 300 .

The first guide unit 110 may include a first guide member 111 and a first height adjusting member 112 .

The first guide member 111 has a rod shape and may be rotatably installed. For example, the first guide members 111 may be formed as a pair, and each may be inclined at both sides of the cable sheath (C). The pair of first guide members 111 may be arranged to form a V shape. Accordingly, the pair of first guide members 111 support the cable sheath C and rotate according to the movement of the cable sheath C, thereby facilitating movement.

The first height adjusting member 112 may be installed below the first guide member 111 . For example, the first height adjusting member 112 may be a bellows tube. Accordingly, by expanding or contracting the length of the first height adjusting member 112, the height of the first guide member 111 can be adjusted.

The second guide unit 120 may include a second guide member 122 , a third guide member 123 and a second height adjusting member 124 .

The second guide member 122 has a rod shape and may be disposed under the cable sheath (C). For example, the axial direction of the second guide member 122 may be horizontal to the ground and perpendicular to the moving direction of the cable sheath (C). A cable sheath (C) may pass through the upper portion of the second guide member 122 . Accordingly, the second guide member 122 rotates according to the movement of the cable sheath C while supporting the cable sheath C, so that the movement can be facilitated.

The third guide member 123 has a rod shape and may be disposed on the side of the cable sheath (C). For example, the third guide members 123 may be formed as a pair and disposed on both sides of the cable sheath C, respectively. The axial direction of the third guide member 123 may be disposed perpendicular to the ground. Accordingly, the third guide member 123 rotates according to the movement of the cable sheath C while supporting both sides of the cable sheath C, so that the movement can be facilitated.

The second height adjusting member 124 may be disposed below the second and third guide members 123 . For example, the lower end of the second height adjusting member 124 may be seated on the ground and the upper end may support the second and third guide members 123 . For example, the second height adjusting member 124 may be a multi-stage bar. Accordingly, the heights of the second and third guide members 123 can be adjusted by withdrawing and retracting the internal rods.

The marking unit 200 may mark print information on the surface of the cable sheath (C). The marking unit 200 may include a marking head 210, a sliding plate 220, and a position adjusting unit 230. The marking head 210 may be disposed on the side of the cable sheath (C). For example, a pair of marking heads 210 may be provided and disposed on both sides of the cable sheathing C, respectively. The marking head 210 may mark the printed information by spraying ink on the cable sheath (C).

The curing unit 300 may be disposed behind the marking unit 200 and irradiate UV light toward the cable sheathing C. For example, the hardened parts 300 may be formed as a pair and disposed on both sides of the cable sheath C. Accordingly, the curing unit 300 may cure the ink ejected from the marking unit 200 .

As another example, the curing part 300 may be formed in a semicircular arc shape. At this time, when the pair of curing parts 300 are disposed to face each other, a circular space is created, and UV light can be irradiated to the ink while the cable coating C passes through this space. Accordingly, even if rotation occurs while the cable sheath C moves, UV light can be irradiated in all directions to cure the ink.

The encoder unit 400 is disposed under the cable sheathing (C) and rotates in contact with the cable sheathing (C) to generate a pulse signal. The pulse signal of the encoder unit 400 is transmitted to the control unit, and the control unit can control the marking unit 200 by measuring the moving length and feed speed of the cable sheathing (C).

The encoder unit 400 may be connected to a first support frame 540 to be described later through an encoder support 420. At this time, the height of the encoder unit 400 can be adjusted by moving the first support frame 540 in the vertical direction through the height adjusting unit 530 . Accordingly, the position of the encoder unit 400 can be adjusted according to the diameter of the cable sheath (C).

An embodiment of the present invention may further include a reset unit (not shown). The reset unit may set the pulse value measured by the encoder unit as a reference pulse value and reset the adjustment counter to 0. The reset unit may include an individual counter reset unit that separately operates counter units and an overall counter reset unit that includes a multi-counter function that multi-operates counter units.

The support unit 500 includes a support plate 510, a support 520, a height adjustment unit 530, a first support frame 540, a second support frame 550, a third support frame 570, and a fourth support frame. (580).

The support plate 510 may be installed on the floor in a predetermined space, and the support 520 may be formed on the upper surface. For example, the support plate 510 has a rectangular plate shape, and an auxiliary support plate 511 may be further connected to each corner. A mounting member 512 seated on the floor may be installed on the lower surface of the support plate 510 . In addition, wheels 513 are installed on the lower surface of the auxiliary support plate 511 to facilitate movement.

The support 520 may be formed perpendicular to the upper surface of the support plate 510 . For example, the supports 520 are formed as a pair, and each may be spaced apart and disposed facing each other. Upper ends of the pair of supports 520 may be connected by a connecting rod 521 .

The height adjustment unit 530 includes a control bar 531, a rotation lever 533, a first power transmission member 534, a second power transmission member 535, a bracket 536, a rotation rod 327, and a fixed rod. (538).

The control bar 531 may be spaced apart from the lower side of the connecting rod 521 between the pair of supports 520 . For example, the control bar 531 has a bar shape extending in the left and right directions, and a protrusion 532 extending toward the second guide part 120 may be formed on a side surface of the control bar 531 .

A rotation lever 533 and a first power transmission member 534 may be installed in the protrusion 532 . For example, the rotation lever 533 may be installed above the protrusion 532 and the first power transmission member 534 may be installed below the protrusion 532 . At this time, since the rotary lever 533 is connected to the first power transmission member 534 by a shaft, the first power transmission member 534 may rotate together with the rotation of the rotary lever 533 .

Meanwhile, a second power transmission member 535, a bracket 536, a rotating rod 327, and a fixing rod 538 may be further installed in the control bar 531.

The second power transmission member 535 may be installed below the control bar 531 . For example, a belt (not shown) is wound around the first power transmission member 534 and the second power transmission member 535, so that the first and second power transmission members 535 may rotate together.

The bracket 536 is connected through the control bar 531, and the second power transmission member 535 may be coupled to the lower portion. In the bracket 536, a rotating rod 327 passes through the center and a bearing may be installed on the inner surface.

The rotating rod 327 is disposed passing through the connecting rod 521 and the bracket 536, and may have a lower end connected to the second power transmission member 535 and an upper end connected to the first support frame 540.

The fixing rod 538 is disposed through the connecting rod 521 , the lower end is connected to the control bar 531 , and the upper end may be fixed to the first support frame 540 .

If the operation process is described based on the configuration of the above-described height adjusting unit 530, first and second power transmission members 535 and the rotation rod 327 are rotated together as the rotation lever 533 is operated. can At this time, while the bearing inside the bracket 536 rotates along the surface of the rotating rod 327 , the control bar 531 may move vertically along the rotating rod 327 . At the same time, while the fixing rod 538 fixed to the control bar 531 is moved in the vertical direction, the first support frame 540 may be moved together.

That is, the height of the encoder unit 400 connected to the first support frame 540 may be adjusted while the first support frame 540 is moved in the vertical direction by manipulating the height adjusting unit 530 .

The first support frame 540 has a bar shape extending a predetermined length and may be disposed in the left and right directions above the height adjusting unit 530 . The encoder support 420 is connected to the upper part of the first support frame 540, and the height of the encoder unit 400 can be adjusted as the first support frame 540 moves in the vertical direction.

The second support frame 550 has a bar shape extending a predetermined length, is disposed in a vertical direction, and may be disposed in front of the first support frame 540 . In this case, the first and second support frames 550 may pass through the first connecting member 560 , respectively. For example, the first connection member 560 may have a hexahedral shape, and the first support frame 540 may pass through both side surfaces and the second support frame 550 may pass through the upper and lower surfaces.

The coupling part 551 has a bar shape extending a predetermined length, is disposed in a vertical direction, and may be connected to the second support frame 550 . At this time, the coupling unit 551 may be connected to the position adjusting unit 230 of the marking unit 200 . That is, the position adjusting unit 230 and the second support frame 550 may be connected via a coupling unit 551 . For example, the coupling part 551 may move along the longitudinal direction of the second support frame 550 . At this time, the height of the marking head 210 may be adjusted as the position adjusting unit 230 moves together.

The third support frame 570 has a bar shape extending a predetermined length, is disposed in the front-back direction, and may have a front end connected to the second support frame 550 .

The fourth support frame 580 has a bar shape extending a predetermined length, is disposed in the left and right directions, and may be disposed above the third support frame 570 . The hardened part 300 may be installed on the upper surface of the fourth support frame 580 .

Meanwhile, the third and fourth support frames 580 may pass through the second connecting member 590 , respectively. For example, the second connecting member 590 has a hexahedral shape, and the third support frame 570 may pass through the front and rear surfaces and the fourth support frame 580 may pass through both left and right sides.

As another example, the position of the curing unit 300 may be adjusted through the third support frame 570 , the fourth support frame 580 and the second connection member 590 . For example, the curing unit 300 may be moved along the longitudinal direction of the fourth support frame 580 so that the left-right position thereof may be adjusted. In addition, by moving the second connecting member 590 along the longitudinal direction of the third support frame 570, the position of the curing unit 300 in the front-back direction may be adjusted. In addition, the height of the hardened part 300 may be adjusted by moving the third support frame 570 along the longitudinal direction of the second support frame 550 .

With the configuration as described above, the cable coating printing system according to an embodiment of the present invention prints information on the cable coating at regular intervals so that the operator can identify product information of the cable.

4 is an enlarged view of the marking portion shown in FIG. 2, FIG. 5 is a plan view of the sliding plate shown in FIG. 4, and FIG. 6 is a side view of the sliding plate shown in FIG.

Referring to FIGS. 4 to 6 , the marking unit 200 may include a marking head 210 , a heating unit 215 , a sliding plate 220 and a position adjusting unit 230 .

The marking head 210 may be disposed on the side of the cable sheath (C). For example, a pair of marking heads 210 may be provided and disposed on both sides of the cable sheathing C, respectively. The marking head 210 may mark the printed information by spraying ink on the cable sheath (C).

For example, the marking head 210 may use UV ink. UV ink is an ink that is cured by reacting to the wavelength of ultraviolet rays when irradiated with ultraviolet rays. As another example, the print information may be a smart code such as a barcode and a QR code. Accordingly, by recognizing the smart code marked on the cable sheath (C) through a reader, product information such as product number, material, length and thickness of the cable can be confirmed. That is, the print information may be a smart code capable of reading product information. As another example, the printing information may further include lot information consisting of a two-dimensional barcode into which information such as a manufacturing date, material, and mixing ratio is input when the cable sheath is pre-manufactured. Accordingly, by recognizing the two-dimensional barcode marked on the cable sheath (C), product information such as the date of manufacture of the cable, material, and mixing ratio can be confirmed. Such print information can be stored in advance in the storage unit, and the storage unit can provide print information to the control unit when the cable coating printing system 10 is operated.

The heating unit 215 may be disposed on an outer circumferential surface of the marking head 210 . The heating unit 215 may transfer heat to the ink provided in the marking head 210 . Ink may be heated by the heating unit 215 and the viscosity may be lowered. Accordingly, it is possible to more easily print information on the cable sheath.

The sliding plate 220 is disposed on the side of the cable sheath (C) and can be coupled with the marking head 210. A coupling hole 221 may be formed on a surface of the sliding plate 220 facing the cable sheath (C). The marking head 210 disposed at one end may be connected to the coupling hole 221 . Ink ejected from the marking head 210 may pass through the coupling hole 221 and adhere to the surface of the cable coating (C). For example, since the inner diameter of the coupling hole 221 decreases toward the cable sheath C side, it is possible to prevent the marking head 210 from protruding toward the cable sheath C side through the coupling hole 221. . In addition, the sliding plate 220 can keep the alignment of the cable coating and the marking head 210 in a line at all times.

The sliding plate 220 may have inclined portions 222 formed on both sides. For example, the inclined portion 222 may be formed on a surface of the sliding plate 220 facing the cable sheath (C). The inclined portion 222 may be inclined in a direction away from the cable sheath (C) toward the end. That is, the inclined portion 222 may be inclined to be farther from the cable sheath (C) toward the end. Accordingly, contact and frictional force between the sliding plate 220 and the cable sheath C can be minimized by the inclined portion 222 . In other words, it is possible to minimize the impact of the inflow of the cable coating and prevent the phenomenon of printing spreading when it is outflow.

In addition, the sliding plate 220 may include a spreading prevention part 225 . The anti-smearing part 225 may extend from the coupling hole 221 and be recessed inwardly. The smudge prevention unit 225 may minimize contact between the sliding plate 220 and the cable sheath C after printing the print information. That is, the smear prevention unit 225 can prevent the print from spreading when the cable coating C is leaked.

The position adjusting unit 230 may include a fixed plate 231 , a movable plate 232 and a rotating member 233 . The position adjusting unit 230 may adjust the horizontal direction coordinates of the marking head 210 . Accordingly, the position of the marking head 210 can be adjusted according to the diameter of the cable sheath (C).

The fixing plate 231 is coupled to the support 500 to be described later, and may be disposed perpendicular to the moving direction of the cable sheath C. In addition, the movable plate 232 may be slidably connected to one surface of the fixed plate 231 .

One surface of the movable plate 232 may be connected to the fixed plate 231 and the other surface may be connected to the marking head 210 . Accordingly, while the movable plate 232 moves along one surface of the fixed plate 231, the horizontal position of the marking head 210 can be adjusted.

The rotating member 233 may be installed on the fixing plate 231 . For example, at least a part of the rotating member 233 is inserted into the fixing plate 231, and the axial direction may be arranged in a vertical direction. As another example, an end of the rotating member 233 located inside the fixed plate 231 is connected to the moving plate 232 in a rack and pinion manner, and as the rotating member 233 rotates, the moving plate 232 moves in the horizontal direction. can be moved

7 is a block diagram showing a control state of a cable coating printing system according to an embodiment of the present invention.

Referring to FIG. 7 , the control unit may receive printing information and production information on the cable sheath (C). The print information is data stored in the storage unit, and includes content to be actually printed in the marking head 210, and may be a smart code such as a barcode and a QR code. The storage unit may be connected to the control unit through the hub, and print information may be transmitted to the control unit when the cable coating printing system 10 operates.

The control unit controls the marking unit 200 according to the pulse signal of the encoder unit 400 to mark the printing information on the cable sheath (C). Production information may include movement speed information and length information.

The moving speed information may be information about the moving speed of the cable sheath (C) detected by the encoder unit 400. For example, the encoder unit 400 may output a predetermined pulse while rotating as the cable sheathing C moves. At this time, it is possible to measure the moving speed and moving distance of the cable sheath (C) based on the output pulse of the encoder unit 400.

The length information may be the total length of the cable sheath produced by the extruder. The total length of the cable sheath to be produced may be input to the extruder, and the inputted length information may be transmitted to the control unit. Accordingly, the controller may set the number of markings of the marking unit 200 based on the input length information. For example, the control unit may calculate the number of markings by setting a marking distance based on length information and a marking interval set by a user. Accordingly, the control unit controls the marking unit to repeatedly perform marking only as many times as the predetermined number of markings, thereby preventing the marking unit 200 from continuing to operate even after production of the cable sheath (C) is completed, resulting in loss of power and ink. can prevent

In addition, the controller may control the marking speed of the marking unit 200 based on the pulse signal of the encoder unit 400 . For example, the marking unit 200 may perform marking every predetermined number of pulse signals. That is, even if the speed of the cable sheathing (C) changes, since the marking unit 200 is controlled by the pulse signal according to the rotation of the encoder unit 400, marking can always be performed at a constant timing.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented herein, and those skilled in the art who understand the spirit of the present invention may add elements within the scope of the same spirit. However, other embodiments can be easily proposed by means of changes, deletions, additions, etc., but these will also fall within the scope of the present invention.
