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 operation can be performed while the marking unit 20 (see FIG. 2B) keeps a predetermined distance from the surface of the marking object MO. The marking unit 20 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 diagram for explaining 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 illustrate a case where the first rail part 221 is provided in the first frame part 210. In FIG. Although the second rail part 222 and the third rail part 223 are provided in the first frame part 210 in FIG. 2A, the number and position of the rail parts may be selectively applied have.

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 FIG. 2B to FIG.

In one embodiment, the second frame 300 may include a second frame portion 310 and a protruding frame portion 311. At this time, the protruding frame portion 311 can be coupled with the pivot support bracket 10, which will be described later, to be pivotable about the first point P1.

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. At this time, the configuration and operation effects of the marking module 100 fixed to the upper portions of the second frame 300 and the third frame 400 are similar to each other and redundant description is omitted.

2B to 3, when the marking object MO1 or MO2 enters the marking system 1000 according to the embodiment of the present invention, the inner surfaces of the marked objects MO1 and MO2 are aligned with the first rail part 221 And the moving direction of the marked objects MO1 and MO2 can be referred to as a first direction. The direction opposite to the first direction may be referred to as a second direction.

The marking module 100 may perform a function of printing various information such as weight and grade on the outer curved surface of the marked objects MO1 and MO2 moved in contact with the first rail 221 .

In one embodiment, the marking module 100 may include a pivotal support 10, a marking portion 20, and a torque applying portion 30. To facilitate understanding, the pivotal support 10 may include a pull inducing portion 11, The head protection unit 12, and the ejection unit 13 will be described separately.

In one embodiment, the pull-in inducing portion 11 can perform a function of guiding the marking object MO to be stably moved toward the head protecting portion 12 by being pivoted about the first point. For this purpose, It is possible to make the distance D1 between the rail part 221 and the first point P1 (hereinafter, referred to as 'first distance') be within a predetermined range.

Here, the first distance D1 can be determined in consideration of the thickness range of the marking object MO1, MO2 that is input to the marking system 1000. [ That is, the first distance D1 and the like can be determined in consideration of both the case where the marking target bodies MO1 and MO2 are inserted into the marking system 1000 and the case where the marking target bodies MO1 and MO2 are large.

In one embodiment, if the first distance D1 is too small, the large semiconductor can not smoothly enter and move between the first rail portion 221 and the pivotal support 10, and if the first distance D1 is too large Not only the marking accuracy by the printer 21 is reduced but also the space usability can be reduced as the facility is unnecessarily enlarged.

Meanwhile, the second point P2 and the third point P3 may be defined to describe the shape of the lead-in inducing portion 11. [

In one embodiment, the second point P2 may be defined as a point located in the second direction relative to the first point P1 in the lead inducing portion 11. [ Here, the distance (P2) between the second point P2 and the first rail 221 in a state where the marked objects MO and MO2 are not in contact with the pivotal support table 10 D2, hereinafter referred to as a "second distance") may be set to have a larger value than the first distance D1 described above. If the second distance D2 is too small, the large semiconductor can not smoothly enter between the first rail 221 and the pivotal support 10. If the second distance D2 is too large, the facility is unnecessarily enlarged Space utilization can be reduced accordingly.

In one embodiment, the third point P3 may be defined as a point located in the first direction P1 with respect to the first point P1 among the lead inducing portions 11. [ The third point P3 may be the first point at which the micro marking object simultaneously contacts the first rail part 221 and the pull-in inducing part 11 when entering the pull-in inducing part 11. [

3, only when the marking object passes through the head protecting portion 12, the head protecting portion 12 can not be rotated until the marking object is pushed by the marking object and rotated to some extent in the counterclockwise direction, The marking accuracy by the printing machine 21 can be improved while the marking object is closely adhered to the marking object. Therefore, the distance D3 (hereinafter referred to as the 'third distance') at which the third point P3 is spaced from the first rail 221 in the initial state is determined by the thickness of the ultra-small marking object . ≪ / RTI > If the third distance D3 is too large, if the small semiconductor is inserted between the first rail 221 and the pivotal support 10, the rotation of the pivotal support 10 is insufficient and the marking accuracy by the printer 21 Can be reduced.

In one embodiment, the surface 11-1 facing the first rail 221 in the lead inducing portion 11 may have a smooth curved shape from at least the second point P2 to the third point P3 , And furthermore, the approximate center of curvature of this curved shape can be located at a position where the distance from the first rail 221 is larger than the second distance D2.

Accordingly, even if the marking object of various sizes is inserted into the marking system 1000, the marking object can be stably passed through the head protection part 12 while minimizing damage to the marking object, thereby improving the accuracy of marking.

On the other hand, the thickness of a small semiconductor is generally about 70 mm, the thickness of a medium semiconductor is about 100 mm, and the thickness of a large semiconductor is about 150 to 200 mm.

In view of this, in one embodiment, the first distance D1 may preferably be in the range of 280-400 mm.

The second distance D2 may be 1.3 to 2.0 times the first distance D1.

Also, the third distance D3 may be about 70 mm

In FIG. 3, reference numeral H1 may denote a distance in which the second point P2 is spaced apart from the first point P1 in the second direction, H2 denotes a third point P3, ) In the first direction. Here, H1 may be determined to be in the range of 0.6 to 1 times the first distance D1. If H1 is excessively small, the marking object MO can not be smoothly guided. If H1 is excessively large, space utilization may be reduced as the facility is unnecessarily enlarged.

The head protection unit 12 may include a marking unit 20 and the head protection unit 12 may include a period in which the marking process for the marked objects MO1 and MO2 is performed. That is to say, the marked objects MO1 and MO2 entered between the first rail part 221 and the pivotal support 10 through the lead-in guide part 11 are stably supported by the first rail part 221 and the pivotal support frame 10 The marking objects MO1 and MO2 are passed through the head protecting portion 12 and the marking portion 20 is moved by the mark protecting portion 12 in the course of passing through the head protecting portion 12. [ Can be achieved.

In one embodiment, the marking portion 20 includes a printer 21. The printing machine 21 may be connected to the server 2100 or the like by wire or wireless. In FIG. 2B, FIG. 3, or the like, the connecting cable 22 is coupled to the printing machine 21. Although not shown here, heads are provided on the surfaces of the printing presses 21 opposed to the marked objects MO1 and MO2, so that information can be printed on the marked objects MO1 and MO2. Further, when the head directly contacts the marked objects MO1 and MO2 in the marking process, the head may be contaminated or damaged, and the accuracy of the printed information may be reduced, so that the distance between the head and the marked objects MO1 and MO2 It needs to be maintained within a certain range, and this function can be performed by the head protecting portion 12. [

For example, as illustrated in FIG. 2A, the marking object MO1 or MO2 may protrude upward or downward in the direction of the pivotal support 10 from a portion where the pivotal support 10 is in contact with the marked object MO1 or MO2. Therefore, in this case, it is also necessary to prevent the head from directly contacting the marking object MO. For this purpose, in the marking system 1000 according to the embodiment of the present invention, The distance T1 from the surface of the surface 12-1 opposed to the projection 221 to the surface excluding the projection 12T-1 may be about 35 mm.

The protrusion 12T-1 may be provided on the surface 12-1 of the head protection portion 12 opposite to the first rail portion 221. The protrusion 12T- And may have a shape protruding curved toward the rail portion 221. In one embodiment, the distance T2 from the highest point of the projection 12T-1 to the head may be about 65 mm.

The pivotal support 10 of the marking system 1000 according to the embodiment of the present invention is rotated around the first point P1 to support the marked objects MO1 and MO2, The distance between the head and the marked objects MO1 and MO2 can be maintained within a certain range while the head is protected by the protrusion 12T-1.

If there is no protrusion 12T-1, the distance between the head and the marking object MO1, MO2 may change during the printing process. In this process, the print quality deteriorates significantly in the portion where the head and the marked objects MO1 and MO2 are excessively distant. However, if the distance between the head and the marking object MO1 or MO2 is excessively narrow, the head can be brought into contact with the marking object MO1 or MO2 during the printing process.

In one embodiment, the protruding portion 12T-1 is formed as an elongated structure of the pivotal support 10, like the shape of the pivotal support 10 contacting the second marked object MO2 in Fig. 2B .

In another embodiment, the protrusion 12T-1 may be replaced by one or more rollers, such as the shape of the pivot support 10 contacting the first marked object MO1 of Fig. 2B. At this time, at least a part of the roller may be coupled to the pivotal support 10 so as to protrude outside the head protection portion 12 toward the first rail portion 221. In this embodiment, the roller may be provided in the space between the printing press 21 and the pivotal support 10 or below the printing press 21. Further, the rollers 25-1, 25-2, and 25-3 may be used as an encoder 25 that senses rotation. In this case, the rotation detection of the roller may be associated with the print start command.

In one embodiment, the printer 21 may be fixedly mounted at one point on the head protection portion 12. [

In another embodiment, the printer 21 may also move linearly on the head guard 12. In this case, a guide rail 23 is provided on the pivotal support 10 and can be coupled to the guide rail 23 so that the printer 21 can be moved forward or backward along the guide rail 23. In this embodiment, a print start command or a movement start command of the printer 21 may be transmitted to the printer 21 by utilizing a roller that performs the function of the encoder 25.

In one embodiment, the projection 12T-1 with a plurality of rollers may be implemented. For example, when the projecting portion 12T-1 is formed by three rollers 25-1, 25-2, and 25-3 as shown in FIG. 3 and the like, a portion of each of the rollers facing the first rail portion 221 The connected virtual line may have a shape corresponding to the protruding portion 12T-1 of the pivotal support 10 contacting the second marked object MO2 in Fig. 2B. In this case, the function of the encoder 25 may be performed using at least one of the rollers. 3, the guide rail 23 provided below the pivot support frame 10 and the printing machine 21 are indicated by solid lines in order to facilitate understanding. In addition, the display of the plurality of rollers is omitted for accurate display of the T1 and T2 portions. The distance indicated by D4 in the figure may refer to the distance that the printer 21 is moved in a straight line according to an embodiment of the present invention. In another embodiment, D4 may mean the width of the protrusion 12T-1.

In one embodiment, the marked objects MO1 and MO2 via the head protection portion 12 can be separated from the first rail portion 221 and the pivotal support 10 via the ejection portion 13. Here, the ejection portion 13 can minimize the damage to the marked objects MO1 and MO2 by the pivot support 10. To this end, the surface 13-1 of the ejector 13 facing the first rail 221 may be curved away from the first rail 221 in the first direction.

In one embodiment, the rotational force applying unit 30 may perform a function of providing a rotational force to the pivotal support 10. In one embodiment, the rotational force applying unit 30 may have one end coupled to the pivotal support 10 and the other end coupled to the protruding frame 311. The pivotal support 10, centered on the first point P1, It is possible to provide the rotation support table 10 with a rotational force in a direction in which the exit portion 13 is brought close to the first rail portion 221 in the rotation of the first rail portion 221. [ Thus, in the initial state, the ejection portion 13 is located nearest to the first rail 221, and the marked objects MO1 and MO2 are positioned between the first rail 221 and the pivotal support 10 The rotation support base 10 is rotated in the direction in which the distance between the exit part 13 and the first rail part 221 is increased. The distance between the exit part 13 and the first rail part 221 is reduced in the process of moving the marked objects MO1 and MO2 in the first direction and leaving the exit part 13, do.

Referring to FIG. 2B, a marking system 1000 according to an embodiment of the present invention may include an entry guide 250. In one embodiment, the entry guide unit 250 is configured such that the marking objects MO1 and MO2 hanging on one side and the other side of the hanger H are positioned between the first frame 200 and the second frame 300 and between the first frame 200 and the second frame 300, 200 and the third frame 400, respectively.

In one embodiment, the hanger H may be provided so that at least one point is coupled to the conveying rail R so that the hanger H can be rotated on the conveying rail R. Further, in order to ensure continuity of work, the hanger H is conveyed along the conveying rail R in the first direction. At this time, if the first and second marked objects MO1 and MO2 enter both the first frame 200 and the second frame 300, the marking process can not be efficiently performed. In the marking system 1000 according to the embodiment, the entry guide 250 may be provided to prevent it.

In one embodiment, the entry guide unit 250 may include a first entry guide roller 250-1, a second entry guide roller 250-2, and a rotation bar 250-3.

In one embodiment, the rotary bar 250-3 is rotatably disposed around a point on the first frame 200, and the first entrance guide roller 250-1 and the second entrance guide roller 250-2 Are coupled to one side and the other side of the rotary bar 250-3 to guide the first marked object MO1 between the first frame 200 and the second frame 300 while contacting and supporting the marked object MO The second marking object MO2 is guided between the first frame 200 and the third frame 400.

4 is a view for explaining the operation principle of a main part according to an embodiment of the present invention.

2B and 4, the first entry guide roller 250-1 is rotated in a state where the marked objects MO1 and MO2 are not in contact with the entry guide 250 (hereinafter, referred to as a 'first state'). The second entry guide roller 250-2 is positioned between the first frame 200 and the third frame 400 and the second entry guide roller 250-2 is positioned between the first frame 200 and the second frame 300 . In addition, the second entry guide roller 250-2 is positioned after the first entry guide roller 250-1 when viewed from the first direction.

4, the hanger H enters the marking system 1000 in a state where the first and second marking objects MO1 and MO2 are sequentially arranged along the first direction The first marking object MO1 comes into contact with the first entry guide roller 250-1 (S110-1). At this time, the first entry guide roller 250-1 is positioned in the direction of the third frame 400 with respect to the conveying rail R, and the rotation axis of the hanger H is positioned on the conveying rail R. Therefore, The first marking object MO1 is moved in the direction of the second entry guidance roller 250-2 while the hanger H is rotated clockwise with respect to the first entry guidance roller 250-2. When the first marking target object MO1 is brought into contact with the second entry guide roller 250-2, the rotation bar 250-3 is rotated in the counterclockwise direction. Accordingly, the first entry guide roller 250-1, And the feed rail R is reduced (S110-2, second state).

The second marking object MO2 is positioned between the first frame 200 and the third frame 400 in the first direction in accordance with the rotation of the hanger H as described above, The second marking object MO2 enters the first frame 200 and the third frame 400 as they are because the entrance guide roller 250-1 is positioned sufficiently close to the vertical lower side of the transfer rail R S110-3, S110-4).

Through the above process, the first marking object MO1 and the second marking object MO2 enter the marking system 1000 and then the rotary bar 250-3 returns to the first state described above. To this end, An elastic means (not shown) such as a spring may be provided. The connection frame unit 240 may be further provided to connect the entrance guide unit 250 to the first frame 200. In one embodiment, the connection frame 240 protrudes from the first frame 200 in the second direction so that the rotation bar 250-3 can be coupled to the connection frame 240 in a rotatable manner .

Although not shown, the first marking object MO1 and the second marking object MO2 may be moved in the direction of the entrance guide 250 in a state where the first and the second marking objects MO1 and MO2 are positioned on one side and the other side of the conveying rail R, respectively . In this case, the first marking object MO1 may first be brought into contact with the second entry guide roller 250-2. In this process, as the rotary bar 250-3 is rotated, The roller 250-1 is brought close to the vertical lower side of the feed rail R so that the second marked object MO2 can be moved in a normal path. To this end, at least a part of the second entry guide roller 250-2 in the first state is located in the area between the first rail 221 and the second frame 300 with respect to the plane perpendicular to the first direction . Accordingly, the first marked object MO1 may not pass through the entry guide unit 250 without contacting the second entry guide roller 250-2. Also, the rotary bar 250-3 may be formed in a bent shape like a boomerang.
