In the marking system 1000 according to an embodiment of the present invention, cows, pigs, etc. are referred to as marking objects (M). However, in addition to livestock products such as cows and pigs, any case where predetermined information such as price, grade, weight, or country of origin must be displayed on a curved surface can be viewed as a marking object (M).

In one embodiment, referring to Figure 6, the inner surface of the marking object (M) is moved while being supported by the first guide rail 720 and the second guide rail 730 installed on the base frame 710, where The moving direction of the marking object M may be referred to as the first direction. And, the direction opposite to the first direction may be referred to as the second direction. Additionally, as illustrated in the drawing, the marking object M may be moved by contacting a pair of semiconductors cut in half with the first guide rail 720 and the second guide rail 730.

In this way, when the marking object (M) enters the marking system (1000), the print head (410) provided in the printing module (400) performs marking work while maintaining a constant distance from the surface of the marking object (M). You can. At this time, the printing module 400 can be connected to various terminals or servers through a wired or wireless communication network to receive information about the marking object (M).

The marking system 1000 according to an embodiment of the present invention is provided to face the first guide rail 720 and the second guide rail 730 in directions symmetrical about the base frame 710, thereby performing efficient marking operations. This can be done.

In one embodiment, the marking system 1000 may include a first guide part 210 and a second guide part 310. In one embodiment, at least one of the front end 211 of the first guide part and the rear end 212 of the first guide part may be bent in a direction away from the first guide rail 720. Accordingly, the marking object (M) entering between the first guide part 210 and the first guide rail 720 can be moved smoothly without being caught or stabbed by the front end 211 of the first guide part, and the marking process is complete. It is possible to prevent the problem of the surface of the marking object (M) being damaged by the rear end 212 of the first guide part in the process of the marking object (M) leaving the first guide part (210). The same applies to the front end 311 of the second guide part and the rear end 312 of the second guide part.

In one embodiment, the marking system 1000 may include a main post 110 provided at a position spaced apart from the base frame 710. At this time, the main post 110 may be installed perpendicular to the ground, but is not limited thereto. In one embodiment, the main post 110 includes a support portion 120 for fixing the marking system 1000, and the support portion 120 may include a first rotation axis 130 perpendicular to the ground.

Referring to Figures 2 and 3, one end of the upper connection bar 213 may be coupled to the first rotation shaft 130 and the other end may be coupled to the first guide portion 210. Additionally, one end of the lower connection bar 313 may be coupled to the first rotation shaft 130 and the other end may be coupled to the second guide portion 310.

At this time, the upper connection bar 213 and the lower connection bar 313 are rotatably coupled to the first rotation axis 130, and the first guide part 210 and the second guide part ( 310) may rotate independently depending on the size of the marking object (M) and come into contact with the outer surface of the marking object (M).

For example, referring to FIG. 7 , the marking object M may be thicker near the second guide portion 310 than near the first guide portion 210 . That is, the distance T1 from the first guide rail 720 at the height of the first guide unit 210 to the marking surface (MS) of the marking object (M) is the distance T1 from the first guide rail 720 at the height of the second guide unit 310. ) may be smaller than the distance T2 from the marking surface (MS) of the marking object (M). Although not shown, a situation may occur where T1 is greater than T2.

The marking system 1000 according to an embodiment of the present invention has an angle at which the first guide unit 210 rotates about the first rotation axis 130 and the second guide unit 310 rotates around the first rotation axis 130. The angles rotated around may be different. Accordingly, even if the shape of the marking surface (MS) of each marking object (M) is different, the risk of differences in printing results can be reduced.

In one embodiment, the first guide part 210 is provided with a first rail part 220, and the first guide part ( 210) and the first rail portion 220 may be combined. In addition, the second guide part 310 is provided with a second rail part 320, and is connected to the second guide part 310 by the first lower auxiliary connecting bar 314 and the second lower auxiliary connecting bar 315. The second rail portion 320 may be coupled.

In one embodiment, the printing module 400 moves forward or backward along the first rail portion 220 and the second rail portion 320 and marks information on the marking object (M).

In one embodiment, the marking system 1000 may further include a resilience application unit 510. This restoring force application unit 510 applies a force to move the rear end 212 of the first guide part and the rear end 312 of the second guide part in a direction closer to the guide rails 720 and 730, to the first guide part 210 and the second guide part 312. It can be provided to the second guide unit 310.

Referring to Figure 5, the restoring force applicator 510 includes a first cylinder rotatably coupled to the first linker 520, and the first linker 520 is rotatably coupled to the connection module 530. You can. Additionally, the rail holder 531 included in the connection module 530 may be rotatably coupled to one side of the first rail portion 220 and rotatably coupled to one side of the second rail portion 320.

Accordingly, even if the first guide part 210 and the second guide part 310 rotate independently about the first rotation axis 130, there is no restoring force in the first rail part 220 and the second rail part 320. It can be delivered.

For example, if the first rail part 220 and the second rail part 320 are not rotatably coupled to the rail holder 531, the first guide part 210 and the second guide part 310 are connected to the first rotation axis. When rotated around (130), excessive stress may be applied to the joint portion of the rail holder 531, the first rail portion 220, and the second rail portion 320, resulting in damage.

Additionally, according to one embodiment of the present invention, the connection module 530 may further include a connection piece 532 and a T-shaped protrusion 533.

In addition, the connecting piece 532 is formed to extend in one direction from the rail holder 531, and the T-shaped protrusion 533 is formed to protrude from the connecting piece 532 and can be coupled to the first linker 520.

At this time, the first linker 520 is formed in an 'L' shape and may include a first part 521 extending in the vertical direction and a second part 522 extending in the horizontal direction. The second part 522 is rotatably coupled to the T-shaped protrusion 533 about an axis perpendicular to the ground, and the first part 521 is rotatably coupled to the first cylinder about an axis horizontal to the ground. You can.

Accordingly, in the process of transmitting the force generated by the restoring force application unit 510 to the first rail unit 220 and the second rail unit 320, the first guide unit 210 and the second guide unit 310 The degree to which the operation of independently rotating around the first rotation axis 130 is interrupted can be minimized.

According to one embodiment of the present invention, the movement force applicator 600 may move the printing module 400 coupled to the first rail unit 220 and the second rail unit 320 forward or backward.

At this time, the moving force applicator 600 may include a second cylinder 610, a rod 620, and a connector 630. Additionally, one side of the connector 630 may be coupled to the rod 620 and the other side may be coupled to the printing module 400. Accordingly, the rod 620 is retracted toward the inside of the second cylinder 610 to move the printing module 400 in the second direction, or the rod 620 is pulled out toward the outside of the second cylinder 610 to print. The module 400 can be moved in the first direction.

As a result, the printing module 400 moves forward or backward in a direction parallel to the marking object (M) along the first rail portion (220) and the second rail portion (320) to the curved surface of the outer surface of the marking object (M). It can perform the function of printing various information such as price, grade, weight, and country of origin.

In one embodiment, the printing module 400 includes a print head 410, a printing frame 420, a first rail joint 430, a second rail joint 440, a roller 450, and an encoder 460. may include.

At this time, the printing module 400 may be coupled to the first rail portion 220 by the first rail coupling portion 430, and may be coupled to the second rail portion 320 by the second rail coupling portion 440. It can be. Referring to FIG. 4, the first rail coupling portion 430 includes a first frame 431, a first slider 432, and a first through hole 433, and the second rail coupling portion 440 includes a second rail coupling portion 440. It may include a frame 441, a second slider 442, and a second through hole 443.

The first slider 432 is coupled to the first rail unit 220 so as to be able to rotate and slide on the first rail unit 220, and the second slider 442 is capable of rotating and sliding on the second rail unit 320. It can be combined with the second rail portion 320.

Additionally, one side of the first frame 431 may be coupled to the first slider 432, and one side of the second frame 441 may be coupled to the second slider 442. At this time, the other side of the first frame 431 and the other side of the second frame 441 may be rotatably coupled to the printing frame 420. In addition, the print head 410 is coupled to the print frame 420, and a marking operation can be performed on the marking object M through the nozzle unit 411 provided in the print head 410.

Accordingly, the vertical angle oriented by the printing module 400 is changed so that the print head 410 performs marking operations at an angle close to vertical to the surface of the marking object (M) regardless of the size or shape of the marking object (M). This can be done.

FIG. 7 is a diagram for explaining the orientation direction of the marking surface MS of the marking object M and the printing module 400 on the first cross-section with the first direction as the normal line.

For example, as illustrated in FIG. 7, even when T1<T2, the direction of the printing module 400 can be maintained close to perpendicular to the marking surface (MS) of the marking object (M), so the printing quality can be improved. You can. In addition, even when T1 and T2 are the same or when T1>T2, the direction in which the printing module 400 is oriented can be maintained close to perpendicular to the surface of the marking object (M) by the same principle. Meanwhile, as illustrated in (b) of FIG. 7, at least one of the first guide part 210 and the second guide part 310 does not contact the marking object (M) and only the roller 450 touches the marking object (M). M) may be contacted.

According to one embodiment, the printing module 400 further includes a roller 450 rotatably provided on the printing frame 420, and the roller 450 is a first roller located above the print head 410. 451 and a third roller 453 and a second roller 452 and a fourth roller 454 located below the print head 410 may be provided.

At this time, the first roller 451 to the fourth roller 454 may be rotated in contact with the curved surface of the outer surface of the marking object M. As a result, the print head 410 can spray ink while maintaining an appropriate distance from the surface of the marking object M. Accordingly, the printing quality can be improved and the risk of contamination or damage to the print head 410 and the nozzle unit 411 provided in the print head 410 can be reduced.

According to one embodiment of the present invention, the printing module 400 may further include an encoder 460, and the encoder 460 is provided on one side of the printing frame 420 and prints according to the rotation amount of the roller 450. You can control the printing progress of the module.

According to one embodiment, after marking content for a specific marking object (M) is transmitted to the printing module 400, the printing process may proceed according to the rotation of the roller 450. If the marking object (M) is relatively large, there is no problem in printing the entire marking content, but if the marking object (M) is relatively very small, the entire marking content is not printed and the marking object (M) comes out. may occur.

For example, assuming that the marking content received by the printing module 400 for a specific marking object (M) is completely printed only when the roller 450 is rotated three times, in the case of a small marking object (M), the roller 450 There may be a case where it is rotated only 1-2 times and passes through the printing module 400 before it rotates completely. In this case, previously unprinted marking content is sprayed onto the next entering marking object (M), resulting in a mismatch between the marking information and the marking object (M), which reduces the reliability of the marking system (1000). It can happen.

Referring to (a) of FIG. 3, it is understood that the distance between the first roller 451 and the third roller 453 may be set to be longer than the distance between the second roller 452 and the fourth roller 454. It could be. Accordingly, by moving the third roller 453 in the first direction and installing it, the third roller 453 can maintain contact with the marking object M until the end.

For this reason, even after the small marking object (M) passes through the print head 410, the third roller 453 is rotated a little more so that the marking content not printed on the small marking object (M) is transferred to the print head 410. It is possible to prevent errors from occurring during the marking process for the next marking object (M) by ensuring that it is all sprayed to the outside.

Referring to FIGS. 8 and 9, the first guide portion 210 may be provided with a first curved protrusion 217. At this time, the vicinity of the rear end 212 of the first guide part is curved to protrude in a direction approaching the first guide rail 720, and then curved in a direction away from the first guide rail 720 to form the rear end of the first guide part ( The first curved protrusion 217 may be formed in a shape that moves the guide rail 212 away from the first guide rail 720. In addition, the first guide part 210 is made to have a smooth curved shape overall, so that the phenomenon of sudden movement of the marking object (M) or the first guide part 210 during the movement of the marking object (M) can be minimized. . Meanwhile, the second guide portion 310 may also be provided with a second curved protrusion, and overlapping descriptions will be omitted.

In the process of moving the marking object (M) in the first direction, the marking object (M) may shake and momentarily move in the second direction. After the printing process of the marking object (M) is completed, the marking object (M) may be moved. If the marking object (M) is shaken in the second direction and comes into contact with or collides with the third roller (453) of the printing module (400) again, a problem may occur where the printed content is out of sync. In this embodiment, In the marking system according to the example, the first guide part 210 is provided with the first curved protrusion 217, so even if the marking object M that has passed the first curved protrusion 217 is shaken and moved in the second direction, the printing module It is possible to fundamentally prevent the problem of the marking object (M) colliding with (400) again.

In one embodiment, the printing module 400 is located closest to the rear end 212 of the first guide part before printing begins, and then the marking object M contacts the first guide part 210. Once started, the printing module 400 moves in the second direction at an appropriate timing to perform printing, and after printing is completed, it can return to the initial position by moving again in the first direction. Here, when the printing module 400 returns to the initial position while the marking object (M) is not sufficiently moved in the first direction, the printing module 400, especially the third roller, is A problem may occur where (453) touches or bumps into the marking object (M). However, in the marking system according to the present embodiment, the first guide portion 210 is provided with the first curved protrusion 217, so that the printing module 400 is in contact with the marking object when it is in contact with the first curved protrusion 217. Since the risk of the marking object M being contacted or bumped into can be significantly reduced, the above-mentioned problems can be prevented.

In one embodiment, the minimum value of the distance from the second cylinder 610 and the rod 620 to the first rail portion 210 is the distance from the second cylinder 610 and the rod 620 to the second rail portion 310.
