Here, when the accommodation space is opened by the opening/closing section 13, it means that the log in the accommodation space can be discharged from the outlet and disposed on the space providing section 20, and the opening/closing section 13 When the receiving space is closed by, it means that the log in the receiving space is heated in the receiving space.

Here, the log discharged from the outlet is cut by the cutting unit 50 and then moved to the receiving space again, which is discharged from the outlet and exposed to the outside, the temperature of the log decreases, and the cutting unit ( This is because cutting by 50) may not be implemented properly. Thus, the log discharged from the outlet is cut by the cutting unit 50 and then moved to the receiving space and heated again, so that the cutting by the cutting unit 50 is smoothly implemented.

At this time, the opening/closing unit 13 is closed upon recovery of the log into the receiving space to increase heating efficiency in the receiving space.

The space providing unit 20 may provide a space in which the log transferred from the receiving unit 10 is seated while being disposed adjacent to the receiving unit 10. In the space providing unit 20, when a cylindrical log is settled, the seated log is placed by placing members on one side and the other side where the intermediate region is concavely formed or moved so as not to deviate from the space providing unit 20. It can be avoided.

The cutting oil may smooth the rotation of the saw blade forming portion with respect to the rotational axis, or when the saw blade portion 53 and the log are in contact, reduce the load on the contact area to make the cutting surface flat.

The saw blade cooling part 63, by spraying cold air into the housing, can prevent the saw blade part 53 or the log from being damaged by heat generated when cutting the log.

The intermediary portion 67 is moved in a position opposite to the second direction (see D2, FIG. 5) or the second direction perpendicular to the first direction (see D1, FIG. 4), or the push section to be described later ( 65) may move the billet seated on the space providing unit 20.

In addition, a grip portion 70 may be connected to the upper side of the intermediate portion 67, and a space in which the position moving portion 85 is mounted may be provided. Here, the position moving unit 85 may be disposed in parallel with the receiving space or out of alignment with the receiving space according to the positional movement of the intermediate unit 67. When the position moving unit 85 is arranged in parallel with the receiving space, the position moving unit 85 may be moved relative to the intermediary unit 67 to allow the log on the space providing unit 20 to flow into the receiving space.

The push portion 65, while disposed adjacent to the space providing portion 20, the billet seated on the space providing portion 20 is a second perpendicular to the first direction (D1, see FIG. 4) It can be pushed in the direction D2 (see FIG. 5).

The position moving unit 85 may press the log on the space providing unit 20 in a third direction opposite to the first direction, and move the log to the receiving unit 10.

Specifically, after the log discharged from the outlet is cut by the cutting unit 50, it is moved to the receiving space again, which is discharged from the outlet and exposed to the outside, the temperature of the log decreases, so that the cutting unit This is because the cutting by 50 may not be implemented properly. Thus, the log discharged from the outlet is cut by the cutting unit 50 and then moved to the receiving space and heated again, so that the cutting by the cutting unit 50 is smoothly implemented.

At this time, the position moving unit 85 may move the log on the space providing unit 20 to the receiving space.

The guide portion 87 is formed toward the extruding device from the lower side of the seating portion 81, the seating portion 81 in a first position adjacent to the space providing unit 20 and the extruding device A movement path may be provided to move to an adjacent second location.

The length measuring unit 91 is installed at the front end of the receiving unit 10, it is possible to measure the length of the log moved from the log supply device to the receiving unit 10.

The mode selection unit 93 may select a log cutting mode based on the length of the log measured by the length measurement unit 91.

Specifically, the log cutting mode is for manufacturing a billet by using the remaining log when the remaining log that does not satisfy the first length occurs while the log provided from the log supply device is cut to the first length. .

Here, the remaining logs that do not satisfy the first length need only satisfy the first length together with a portion of the next log provided from the log supply unit, and at this time, the remaining logs and a portion of the next log are separated and extruded. It can be moved because the extruding process has no problem even if the remaining log and a portion of the next log are moved to the extruder while being separated.

On the other hand, when the log is cut by the saw blade part 53, both ends of the log to be cut are subjected to shear force by the saw blade part 53. At this time, when either one of the both ends of the cut log is short , It is not supported by the shearing force, and one short end may be crushed by the saw blade part 53.

Therefore, if the remaining log is generated, or the length of a portion of the next log to be cut is maintained at a minimum length so as not to be deformed by the shear force by the saw blade part 53.

The log cutting mode may be a normal mode, a half-minute mode, a discharge mode, and a recovery mode, depending on the length of the log remaining after being cut by the cutting unit 50.

The general mode is a setting for cutting a log seated in the space providing unit 20 to the first length.

The half-half mode is a setting for halving the length of the log seated on the space providing unit 20.

The discharge mode is a setting for moving the log seated in the space providing unit 20 to the seating unit 81 without cutting.

The recovery mode is a setting for moving the log seated in the space providing unit 20 to the receiving unit 10 without cutting.

The control unit 95, the cutting unit 50, the transfer unit 30, the grip unit 70, the push unit 65 or the position moving unit according to the cutting mode selected by the mode selection unit 93 (85) can be controlled.

Meanwhile, the billet processing system 1 according to an embodiment of the present invention may further include a burnout part 97.

4 to 7 are schematic diagrams for explaining a general mode of a billet processing system according to an embodiment of the present invention.

4 to 7, in the general mode of the billet processing system 1 according to an embodiment of the present invention, the length L of the log seated on the space providing unit 20 is as follows: It may be the case where 1 or Equation 2 is satisfied.

[Equation 1]

L = B + m

[Equation 2]

L = B + m + E (0 <E <B-2m)

Here, L is the length of the log, and B is the length of the billet to be manufactured, that is, the first length described above. In addition, m means the minimum length that the log will not be damaged when cutting the log by the saw blade portion 53.

In detail with respect to Equation 1, for example, if B (the first length) is 8 and m is 2 (hereinafter, the length code is omitted), the length of the log set on the space providing unit 20 is 10, Even when cutting to the first length 8, since the length of the remaining portion is 2, which satisfies the minimum length, the log may be cut.

In detail with respect to Equation 2, for example, if B (first length) is 8, m is 2, and E is greater than 0 and less than 4 (8-4), the length of the log is greater than 12 and 14 Since it is smaller, even if it is cut to the first length 8, since the length of the remaining log is greater than 4 and less than 6, the cutting of the log on the space providing unit 20 can be implemented, and the cutting of the next log is also the minimum length It can be longer and cutting can be implemented.

In the general mode, the control unit 95 controls the transfer unit 30 and the cutting unit 50 so that the log seated in the space providing unit 20 is cut to the first length, and the control unit 95 The push portion 65 may be controlled so that the billet cut in one length moves to the seating portion 81.

Specifically, when the organic operation of each component in the general mode is described in time series, after the transfer unit 30 transfers the log on the receiving unit 10 to the space providing unit 20, The cutting unit 50 cuts the log on the space providing unit 20 to a first length, and the billet manufactured by cutting is moved to the seating unit 81 by the push unit 65, and then the It can be moved to the extrusion device.

In FIG. 4, the log L moved by the transfer unit 30 is cut by the cutting unit 50 to become a billet (see B, FIG. 5 ), and a seating portion by the push unit 65 Go to (81).

At this time, the log on the space providing unit 20 is moved to the accommodation space by the position moving unit 85 (see FIG. 6).

In addition, referring to FIG. 7, the billet B on the seating portion 81 moved along the guide portion 87 is processed by the burnout portion 97.

8 is a schematic view for explaining a discharge mode of a billet processing system according to an embodiment of the present invention.

Referring to FIG. 8, in the discharge mode of the billet processing system 1 according to an embodiment of the present invention, the length L of the log seated on the space providing unit 20 satisfies Equation 3 below. It may be.

[Equation 3]

L = B

Here, L is the length of the log, and B is the length of the billet to be manufactured, that is, the first length described above.

In detail with respect to Equation 3, for example, when B (the first length) is 8, the length of the log seated on the space providing unit 20 is 8, so the first length 8 is satisfied. It may be moved to the seating portion 81 without.

In the discharge mode, the control unit 95 may control the push unit 65 such that the log seated in the space providing unit 20 is not cut, but moved to the seating unit 81.

Specifically, if the organic operation of the components in the discharge mode is described in time series, the log settled in the space providing unit 20 satisfies the billet without cutting, so the push unit 65 allows the After being moved to the seating portion 81, it can be moved to the extrusion device.

9 to 11 are schematic views for explaining a half-half mode of the billet processing system according to an embodiment of the present invention.

9 to 11, in the half mode of the billet processing system 1 according to an embodiment of the present invention, the length L of the log seated on the space providing unit 20 is as follows: It may be a case where 4 or Equation 5 is satisfied.

[Equation 4]

L = B + m + E (B-2m <E <B-m)

[Equation 5]

L = B + E (0 <E <m)

Here, L is the length of the log, and B is the length of the billet to be manufactured, that is, the first length described above. In addition, m means the minimum length that the log will not be damaged when cutting the log by the saw blade portion 53.

In detail with respect to Equation 4, for example, if B (first length) is 8, m is 2, and E is larger than 4 (8-4) and smaller than 6 (8-2), the space providing unit Since the log settled at (20) is larger than 14 and smaller than 16, after cutting to the first length (8), the remaining log is larger than 6 and smaller than 8, so the cutting of the next log is smaller than the minimum length, so cutting It may not be implemented properly.

Accordingly, after the cutting, the remaining logs larger than 6 and smaller than 8 can be halved, so that the remaining 2 logs larger than 3 and smaller than 4 can be manufactured.

The remaining two logs thus produced can be transferred to the extrusion device together with the next cut log.

In detail with respect to Equation 5, for example, if B (first length) is 8 and E is greater than 0 and less than 2, the log settled in the space providing unit 20 is greater than 8 and less than 10. , When cutting to the first length (8) is greater than 0 and less than 2, since the cutting becomes smaller than the minimum length, cutting may not be properly implemented.

Accordingly, the log larger than 8 and smaller than 10 seated on the space providing unit 20 can be halved, so that the remaining 2 logs larger than 4 and smaller than 5 can be manufactured.

The control unit 95, in the case of the half-minute mode, the log 30 seated in the space providing unit 20 is divided into the first log piece (B1) and the second log piece (B2) so that the transfer unit 30 and The cutting unit 50 may be controlled, and the grip unit 70 may be controlled to be spaced apart from the space providing unit 20 while the first log piece B1 is gripped by the grip unit 70. .

The second log piece B2 may form another log L1 accommodated in the receiving part 10 and first billets L1, B2 of the first length (see FIG. 10).

Specifically, when the organic operation of the component in the half-minute mode is described in time series, the cutting unit 50 cuts the log on the space providing unit 20 in half, and the grip unit 70 is , Grip the first half-half log piece (B1) to lift.

Thereafter, the position moving unit 85 is driven so that the second log piece B2 seated on the space providing unit 20 moves to the accommodation space. At this time, the first log piece B1 that is raised while being gripped by the grip portion 70 is maintained in that state.

Next, the second log piece (B2) and the next log (L1) in the accommodation space by the transfer unit 30 are located on the space providing unit 20 together, the second log piece (B2) and the next log The point at which the sum of the lengths of the portions of (L1) becomes the first length is cut by the cutting unit 50.

Then, a portion of the log (L1) and the second log piece (B2) after being cut by the cutting portion 50 are moved to the seating portion 81 by the push portion 65, and then the extrusion device Is moved to.

Thereafter, the first log piece B1 gripped by the grip part 70 is seated on the space providing part 20 and moved to the accommodation space by the position moving part 85.

Next, the first log piece (B1) and the next log (L2) are located on the space providing unit 20 together, and the sum of the lengths of a portion of the first log piece (B1) and the next log (L2) The point that becomes the first length is cut by the cutting unit 50.

Then, a part of the log (L2) and the first log piece (B1) after being cut by the cutting part 50 are moved to the seating part 81 by the push part 65, and then the extruding device Is moved to.

12 is a schematic view for explaining a recovery mode of a billet processing system according to an embodiment of the present invention.

Referring to FIG. 12, in the recovery mode of the billet processing system 1 according to an embodiment of the present invention, the length L of the log seated on the space providing unit 20 satisfies Equation 6 below. It may be.

[Equation 6]

L = E (m ≤ E <B-m)

Here, L is the length of the log, and B is the length of the billet to be manufactured, that is, the first length described above. In addition, m means the minimum length that the log will not be damaged when cutting the log by the saw blade portion 53.

In detail with respect to Equation 6, for example, if E is greater than or equal to 2, and less than 6 (8-2), the length of the log settled in the space providing unit 20 is greater than or equal to 2, 6 Since it is smaller, it cannot be cut because it does not meet the first length.

In addition, since the cutting can be implemented by being longer than the minimum length of the next log, the log settled in the space providing unit 20 is recovered as an accommodation space.

In the recovery mode, the control unit 95 may control the position moving unit 85 so that the log seated in the space providing unit 20 is not cut, but moved to the receiving unit 10.
