Figure 1 is a schematic diagram that schematically illustrates an example of use of a marking system 1000 in accordance with an embodiment of the present invention.

Referring to Fig. 1, the livestock products such as cattle, swine and the like are generally measured in a state of being cut in half by a line extending from the tail portion to the neck portion, and the weight is generally measured and judged by the judgment yarn.

In the marking system 1000 according to an embodiment of the present invention, such cattle, pigs, and the like are referred to as a marking object (MO). However, in the case where predetermined information such as price, grade, weight, and country of origin should be displayed on the curved surface in addition to livestock products such as cattle and pigs, all of them can be regarded as a marking object (MO).

First, the weight of the marking object MO can be measured by the measuring instrument 2200. At this time, the measured weight information may be stored in a separate server 2100 connected to a wired or wireless communication network.

Next, when the marking object MO is moved to the place where the judgment yarn is located, the judging person can check the inside and outside of the marked object MO to judge the grade. The rating information thus determined may be input through a separate input terminal 2300 and the input terminal 2300 may be connected to the server 2100 through a wired or wireless communication network so that the rating information is transmitted to the server 2100 can do.

The marking object MO may be fixed to the hanger H or the like and the hanger H may be transported along a separate conveying rail R or the like fixed to the ceiling or the like. Here, as illustrated in the figure, the marking object MO may be one in which a pair of halves of semiconductor chips are fixed to one hanger H.

When the marking object MO enters the marking system 1000 in this manner, the marking unit 40 (FIG. 4) can perform the marking operation while maintaining a constant gap with the surface of the marking object MO. The marking unit 40 may be connected to the server 2100 through a wired or wireless communication network and may receive information to be marked on the marking object MO from the server 2100.

FIG. 2A is a front view schematically illustrating a marking system 1000 according to an embodiment of the present invention, FIG. 2B is a plan view schematically illustrating a marking system 1000 according to an embodiment of the present invention, FIG. 3 Is a perspective view schematically illustrating a second frame 300 of a marking system 1000 according to an embodiment of the present invention.

2A through 3, a marking system 1000 according to an embodiment of the present invention may include a marking module 100, and further includes a second frame (not shown) to which the marking module 100 is coupled 300, a first frame 200 spaced apart from the second frame 300, and the like.

Also, a third frame 400 provided in a direction symmetrical to the second frame 300 about the first frame 200 may be provided. When a pair of semiconductors in which the marking object MO is cut in half is fixed to one hanger H, a more efficient marking operation can be performed by providing the third frame 400.

First, the first frame 200 may include a first frame part 210 provided perpendicularly to the paper surface. At this time, at least one rail portion may be provided on the first frame 200 while being parallel to the moving direction of the marked object MO. 2A and 2B, the first rail part 222 is fixed to the first frame part 210 by the first fixing bar and the second rail part 232 is fixed to the first frame part 210 by the second fixing bar 231. [ And the number and position of the rail portions may be selectively applied as needed.

Next, the marking module 100 may be coupled to the upper portion of the second frame 300. The marking module 100 will be described later with reference to FIGS. 3 to 5C.

At this time, the angle of the second frame 300 with the ground can be changed.

That is, the lower part of the second frame part 310 can be rotatably coupled to the base part 301 fixed to the ground.

Also, at least one rail portion may be provided on the second frame 300 while the second frame 300 is parallel to the moving direction of the marked object MO. 2A and 2B, the third rail part 322 is fixed to the second frame part 310 by the third fixing bar 321 and the fourth rail part 332 is fixed to the fourth fixing bar 331 The second frame part 310 is fixed to the second frame part 310. However, the number and positions of the rail parts can be selectively applied as needed.

On the other hand, the angle formed by the second frame 300 with the ground may be 90 degrees or less. If the angle between the second frame 300 and the paper surface is too small, the upper portion of the second frame 300 may be too close to the first frame 200. In this case, May not enter between the first frame 200 and the second frame 300. Therefore, the minimum value of the angle formed by the second frame 300 with the ground must be determined within a range in which the marking object MO can enter between the first frame 200 and the second frame 300. Here, the minimum value of the angle formed by the second frame 300 with the paper may be determined depending on the type of the marking object MO on which the marking system 1000 according to the embodiment of the present invention performs the marking operation. That is, the minimum value may be different when the marked object MO is beef cattle or pigs. For example, in a case where the marking object MO is pig, a conductor having a minimum thickness among the conductors to be classified can be entered between the first frame 200 and the second frame 300, And the paper surface may be determined as the minimum value of the angle formed by the second frame 300 and the paper surface.

Since the marking module 100 is provided on the upper portion of the second frame 300, in order to smoothly perform the marking operation, the upper portion of the second frame 300 is held in the first frame 300 200 direction.

Accordingly, the marking system 1000 according to an embodiment of the present invention may include support means.

For example, the configuration including the second base portion 341, the cylinder 342, and the piston 343 illustrated in Figs. 2A to 3 may mean a support means.

The second base portion 341 may be fixed to the ground or the base portion 301 and the cylinder 342 may be pivotally coupled to the upper portion of the second base portion 341. [ In addition, one end of the piston 343 is coupled with the cylinder 342, and the length of insertion into the cylinder 342 can be varied. The other end of the piston 343 may be fixed to the second frame 300 and the other end of the piston 343 may be coupled with the first sub frame part 311 fixed to the second frame part 310 It is possible.

Here, the distance between the other end of the piston 343 and the cylinder 342 can be varied within a predetermined range. In this range, a force is applied to bring the other end of the piston 343 closer to the cylinder 342 Which can be realized by using hydraulic pressure, pneumatic pressure, elastic force of a spring, or the like.

Accordingly, the acute angle formed by the second frame 300 and the ground may be greater than the minimum value described above, and the upper portion of the second frame 300 may be provided with a force to be close to the first frame 200.

In an embodiment, the third frame 400 symmetrical to the second frame 300 may be further provided at a position symmetrical to the second frame 300 with respect to the first frame 200. Here, the configuration and operation effects of the marking module 100 fixed to the upper portions of the third frame 400 and the third frame 400 are similar to those described above, and redundant description will be omitted.

Although not shown, this elastic force may be realized by providing a torsion spring at a coupling point between the connection frame 41 and the second support portion 30. [

Further, an encoder 45 connected to the first roller 43 or the second roller 44 may be further provided.

Here, the encoder 45 may perform a function of detecting whether the first roller 43 rotates. As the marking object MO moves, when the first roller 43 comes into contact with the marked object MO, the rotation starts. The encoder 45 recognizes this point of time and sends it to a separate control means (not shown) A signal is transmitted to start the movement of the first support portion 20, the second support portion 30, and the marking portion 40, and a marking operation can be performed.

The encoder 45 may be connected to the second roller 44 as shown in the figure. In this case, the first roller 43 and the second roller 44 may be rotated by the first roller 43 and the second roller 44, 43 and a timing belt 46 contacting the outer circumferential surface of the second roller 44.

A second gear 63 is fixed to the other end of the guide rail 10 or the upper end of the second frame 300 and a drive belt 64 connected to the second gear 63 and the first gear 62 .

The belt fixing portion 23 of the first support portion 20 is fixed to the drive belt 64 so that the first support portion 20 moves in the first direction or the second direction in accordance with the movement of the drive belt 64 It can be.

Hereinafter, the operation principle of the marking module 100 according to an embodiment of the present invention will be described with reference to FIGS. 5A to 5C.

5A illustrates an initial state in which the marking portion 40 is brought into contact with the marked object MO.

Since the first roller 43 is located farther away from the second support 30 than the second roller 44, the first roller 43 is first brought into contact with the elliptical marking object MO, It is possible to secure a state in which the printing nozzles N maintain a certain distance from the marked object MO. When the first roller 43 comes into contact with the marked object MO and starts to rotate, the encoder 45 senses the rotation of the first roller 43 and transmits a signal to the control unit, The second support portion 30, and the marking portion 40 can start to move. At this time, the first support part 20 starts to move in the second direction opposite to the first direction, which is the movement direction of the marked object MO.

Next, the following operation will be described with reference to FIG.

Assuming that the marking object MO advances in such a manner that the front of the marking object MO faces the first direction, in the state as illustrated in FIG. 5A, the printing nozzle N is positioned on the front side of the marking object MO 5B, the printing nozzles N are located at a predetermined distance from the intermediate surface of the marking target object MO, as shown in FIG. 5B.

When the marking object MO is a conductor such as a bulb or a pig, generally the middle portion of the marking object MO is thickest. 5B, the markers 40, particularly the first and second rollers 43 and 43, are in contact with the surface of the marked object MO, the first roller 43 and the second roller 44, The distance between the second roller 44 and the first support portion 20 may be shortest. Here, since the marking portion 40 to which the printing machine I is fixed can not be varied in size, the absolute position of the marking portion 40 itself is smaller than the state illustrated in FIG. 5A toward the first supporting portion 20 Should be moved. For this, in the marking system 1000 according to an embodiment of the present invention, the second support portion 30 can be moved in a direction approaching the first support portion 20. [

Accordingly, even when the marking object MO is formed in an elliptical shape or the like, and the surface on which the information is to be marked is a curved surface, the printing nozzle N can maintain a certain distance from the surface of the marking object MO.

Next, referring to FIG. 5C, as the printing nozzle N is moved rearward of the marked object MO, the second supporting portion 30 is returned to a position similar to the position illustrated in FIG. 5A, and the marking portion 40 are rotated in a direction opposite to the direction illustrated in FIG. 5A, so that the distance between the printing nozzle N and the marked object MO can be kept constant.

Here, the second support portion 30 may be moved in a direction away from the first support portion 20 by an elastic force provided by the second spring SP2.

When the process described above is completed, the driving means 60 moves the first support portion 20 in the first direction to return to the initial position, and the elastic force provided by the first spring SP1 and the second spring SP2 The marking module 100 may be returned to the state illustrated in FIG. 5A.

Accordingly, uniform quality marking can be performed on the curved surface of the marking object MO entering the marking system 1000 at regular intervals.

6 is an enlarged fragmentary plan view of a main part of a first frame 200 according to an embodiment of the present invention.

Referring to Figs. 1 and 6, when the marked object MO is a conductor such as a cow or a pig, the judgment yarn is usually positioned in the tail direction of the conductor to determine the grade of the conductor.

On the other hand, the marking object MO enters the marking system 1000 along the conveying rail R in a state where the marking object MO is caught by the hanger H, and as shown in FIG. 1, It is difficult to efficiently carry out the marking operation when the conveying rail R is provided so as to pass through the marking system 1000.

In particular, when the marking object MO is a conductor such as a cow or a pig, it is generally advantageous to improve the marking quality by performing a marking operation from the tail side to the opposite direction.

Therefore, when the marking object MO enters the marking system 1000, entering the marking object MO in a state in which the tailing direction is directed toward the first direction can improve the efficiency of the marking operation. The marking system 1000 according to the embodiment may further include an entry guide unit 240.

The entrance guide unit 240 is formed so that the point P1 that is the maximum distance from the first frame 200 to the second direction side is located near the third frame 400 or the fourth frame side about the first frame 200 .

Here, as shown in the drawing, the entrance guide unit 240 may include the entry guide roller 242 to allow the marking object MO to be rolled more efficiently.

In one embodiment, the synchronizing switching means 261 and 262 for simultaneously opening and closing the first frame 200 and the second frame 300 and the first frame 200 and the third frame 400 .

According to an embodiment, as illustrated in the drawing, synchronous opening / closing means 261 and 262 are axially coupled to the first frame portion 210 so that all of the marked objects MO contact the synchronizing opening / closing means 261 and 262 The marking object MO can be introduced into the marking system 1000 when the synchronizing opening and closing means 261 and 262 are opened.

Thus, according to the embodiment, the marking operation can be performed with uniform quality while simultaneously performing the marking operation on the two marking objects MO, and the tail portion of the marking object MO is moved in the direction of the marking start point The marking object MO can be introduced into the marking system 1000 so that the quality of the marking can be improved.
