Description

  The present invention relates to a wood processing device capable of processing wood, a control device for the wood processing device, and a wood processing program.

  Conventionally, joining by tenon joint is known as a joining part of wood (building material) used for a wooden house. In order to join two pieces of wood, a convex portion called “tenon” is formed at the end of one column, and a tenon hole is formed in another column provided at a position intersecting with the column. Then, the two columns can be joined with higher strength than the joining by the wood screw by fitting the “tenon” of one column to the tenon hole of another column and joining them.

  As a column in which “mortises” are formed on both ends, a column called a shed bundle used for a framework of a roof portion of a building may need a short length. It is difficult to process such a tenon on both ends of such a short column by a wood processing apparatus represented by precut processing. For this reason, as a technique for processing this type of short column with good yield and safety, after processing multiple columns in a continuous state, the column is cut to the length of each column, Has been proposed (see Patent Document 1).

  However, when processing is performed in a state where a plurality of columns are connected, the portion where the joint portion is formed with respect to the columnar material is formed thin, so that the strength of the portion is lowered. If the length of the column is short, there may be a state where a joint is interposed between the position where the material is held at a fixed position (clamp position) during processing and the processing position. Due to the force input to the material, there is a possibility that the vicinity of the joint having low strength may be damaged.

  In addition, when there are many columns in a continuous state, the number of joints interposed between the clamping position and the machining position may increase, and in this case, damage near the joints is possible. Increases nature. For this reason, it may be difficult to manufacture a plurality of columns having joints on both ends, such as the need to reduce the processing speed or the limitation of usable tools. There was a point.

  In addition, since the portion where the joint is formed is thin, the rigidity is low, and there is a possibility that the material may be displaced due to the force input from the clamp position to the machining position separated by the joint. is there. For this reason, unless the processing speed is slowed down, it is difficult to produce a plurality of columns having joints on both ends with a certain level of accuracy, and it may take a long time for processing. was there.

Further, the moving mechanism of the upstream side cutting portion 34 does not necessarily need to be configured so that the rotation center axis of the cutting tool 34A can move outside the outer peripheral surface of the material wood 9, and a part of the outer peripheral surface (for example, , Only two surfaces) can be processed, and the movable range may be set so that the remaining portion can be processed by the rotation of the rotating portion 36.

  The downstream cutting unit 35 is a device that performs a cutting process capable of forming a planar portion by moving the rotating blade while contacting the wood, similarly to the upstream cutting unit 34, and the upstream cutting unit 34 is configured such that the distance from the rotation center axis to the blade portion is different. Specifically, the downstream cutting unit 35 includes a cutting tool 35A, a driving device (not shown) that rotates the cutting tool 35A, and a moving mechanism (not shown) that moves the cutting tool 35A. . Further, the downstream cutting portion 35 is set such that the distance R5 from the rotation center axis to the blade portion is longer than the distance R4 in the upstream cutting portion 34, and groove-like machining is performed from the direction side intersecting the longitudinal direction of the material wood 9. In such a case, the degree of freedom of the shape that can be machined is higher than that of the upstream cutting portion 34. By properly using the upstream side cutting part 34 and the downstream side cutting part 35, it is possible to efficiently manufacture a building material including joining members having various shapes from the material wood 9.

  The cutting tool 35A of the downstream side cutting portion 35 is configured to have a size capable of forming the peripheral surfaces of the rear end joint portions 13 and 23 (outer peripheral surfaces excluding the rear end surfaces 13B and 23B) from the outside of the outer peripheral surface of the material wood 9. Thus, it is possible to process the wood that has entered the range of the substantially cylindrical outer peripheral portion by the rotation operation. Further, the cutting tool 35A is formed to have a shorter length along the longitudinal direction of the material wood 9 than the cutting tool 34A of the upstream side cutting portion 34, and a short length groove that cannot be processed by the upstream side cutting portion 34. Can be formed.

  In addition, the moving mechanism of the downstream-side cutting unit 35 allows the cutting tool 35A to be cut from the outside with respect to only a part of the outer peripheral surface along the longitudinal direction of the material wood 9, and has a movable range. Is set. Specifically, the cutting tool 35 </ b> A has a larger outer shape than the cutting tool 34 </ b> A of the upstream-side cutting portion 34, and therefore it is necessary to separate the rotation center axis from the material wood 9 in processing the material wood 9. The movable range is set so that cutting can be performed on some of the adjacent side surfaces (for example, a combination of the side surface 9m and the side surface 9n and a combination of the side surface 9M and the side surface 9N) (see FIG. 6 (a) and FIG. 6 (d)).

  Here, the cutting tool 34A of the upstream side cutting portion 34 is configured such that the distance R4 from the rotation center axis to the location where the blade portion is provided is shorter than the distance R5 in the cutting tool 35A. In the case of cutting with the cutting tool 34A of the cutting part 34, it is possible to make the positional deviation caused by the resistance force by cutting the material wood 9 smaller than in the case of cutting with the cutting tool 35A of the downstream side cutting part 35. Further, the cutting tool 34A of the upstream cutting portion 34 is also used for the moving distance necessary for cutting the surfaces (for example, one side surface and the bottom surface) facing the plurality of directions of the outer peripheral surface of the material wood 9. Can be made shorter than the case of using the cutting tool 35A of the downstream cutting portion 35. That is, when cutting with the cutting tool 34A of the upstream side cutting portion 34, the material wood 9 can be processed with high accuracy in a short time.

  The cutting tool 34A of the upstream cutting unit 34 and the cutting tool 35A of the downstream cutting unit 35 may be configured to operate independently of each other, or may be configured to operate integrally. Also good. For example, two cutting tools 34A and 35A may be provided side by side on a common rotating shaft, and may be rotated by a common driving device and moved by a common moving mechanism, or may be a material wood 9 may be configured such that at least one of movement along the longitudinal direction of 9 and movement in a direction intersecting the longitudinal direction of the material wood 9 operate independently. Further, it is not always necessary to provide two cutting parts, that is, the upstream cutting part 34 and the downstream cutting part 35. For example, only one downstream cutting part 35 is provided, and one type of cutting is performed. It is good also as a structure cut with a tool, and it is good also as a structure which has three or more cutting parts and cuts with three or more types of cutting tools. Further, the downstream cutting portion 35 is not necessarily configured to be able to cut only a part of the peripheral surface of the material wood 9, and is movable over the entire circumference of the material wood 9. It is good also as a structure which can cut with respect to all the surrounding surfaces.

  The rotating part 36 is configured to be able to rotate the material wood 9 at an angle of 90 degrees around the longitudinal direction, and intersects the longitudinal direction of the material wood 9 by making the number of rotations a plurality of times. The side surfaces 9m, 9n, 9M, and 9N that face the direction can be arranged so as to face a specific direction. For example, when the material wood 9 is reversed, the 90 ° rotation may be performed twice.

  The rotating unit 36 may be any material that can rotate the material wood 9 at a preset angle, and may be configured to rotate 180 degrees by one operation, or a column having an octagonal or hexagonal cross section. In such a case, it may be configured to rotate at 45 degrees or 60 degrees in one operation, and an angle suitable for cutting is selected from a plurality of types of rotation angles (for example, 45 degrees, 60 degrees, and 90 degrees). It may be configured to be selected and rotatable. Moreover, it is not always necessary to provide the rotary part 36 in the wood processing machine 2, the movable range of the cutting parts 34, 35, the shape of the joining parts 12, 13, 22, 23 of the joining members 10, 20 to be manufactured and Depending on the setting of the formation position, the material wood 9 may not be rotated during the manufacturing process. For example, the downstream side cutting portion 35 is configured to be movable within a range where cutting can be performed with respect to all of the outer peripheral surface of the material wood 9, and can be applied to all of the outer peripheral surface without rotating the material wood 9 during the manufacturing process. You may enable it to process with respect to it.

  Next, the manufacturing process of the joining members 10 and 20 will be described with reference to FIGS. FIG. 3 is a view for explaining positions where the joining members 10 and 20 are formed by processing the material wood 9, and FIG. 3A is a top view of the material wood 9, and FIG. b) is a front view of the material wood 9. FIG. 4 is a flowchart showing the joining member processing for producing the joining members 10 and 20, and FIG. 5 shows the process of producing the joining members 10 and 20 from the material wood 9 for each process. It is the shown front view.

  Here, in each figure of Fig.5 (a)-FIG.5 (j), the state seen from the side which cross | intersects a conveyance direction by making the upstream of the conveyance direction of the material timber 9 into the right side and downstream is the left side. Is shown. Further, FIG. 5A shows a state after processing by the partial cutting step S2, FIG. 5B shows a state after processing by the partial cutting step S3, and FIG. A state after the reversing step S4 is shown, and FIG. 5D shows a state after the processing by the cutting step S5. FIG. 5 (e) shows a state after processing by the forming step S6, FIG. 5 (f) shows a state after processing by the remaining cutting step S7, and FIG. 5 (g) shows separation. The state after processing in step S8 is shown. Further, FIG. 5 (h) shows a state after processing by the forming step S9, FIG. 5 (i) shows a state after processing by the remaining cutting step S10, and FIG. The state after processing by Step S11 is shown.

  FIG. 6 is a cross-sectional view showing the manufacturing process of the joining portions 12 and 13 of the first joining member 10, and each of FIGS. 6A to 6D shows the AA section of FIG. It is the cross-sectional shape which cut | disconnected the junction parts 12 and 13 of the member 10 for 1st joining by the line and the BB cutting line, Comprising: The shape after the process in each process is shown. FIG. 6A shows the shape after the machining by the partial cutting step S3, and also shows the movement path of the cutting tool 35A. Similarly, FIG. 6B shows the cross-sectional shape after reversal in the reversing step S4 and the rotation direction of the material wood 9, and FIG. 6C shows the shape after processing in the forming step S6, The moving path of the cutting tool 34A is shown, and FIG. 6D shows the shape after processing in the remaining cutting step S7 and the moving path of the cutting tool 35A.

  In FIG. 6, only the joining portions 12 and 13 of the first joining member 10 are illustrated, and the joining portions 22 and 23 of the second joining member 20 are cut and processed with respect to the first joining member 10. Since the subsequent shapes are the same, illustration is omitted, and only the step numbers in the joining member processing are shown in parentheses.

  The process of processing the material wood 9 to manufacture the joining members 10 and 20 is performed by controlling the operation of the wood processing machine 2 by the drive control device 3, and this control is stored in the drive control device 3. This is performed according to the joining member processing as part of the program to be executed. In addition, as shown in FIGS. 3A and 3B, the joining members 10 and 20 having the shape indicated by the alternate long and short dash line are manufactured by the joining member processing as shown in FIG. The

  Here, at the time of manufacturing the joining members 10, 20, before each processing on the material wood 9 by the cutting portion 33, the upstream side cutting portion 34 and the downstream side cutting portion 35, or the material wood by the rotating portion 36. A process (process) in which the material wood 9 is transported by the transport unit 31 before the rotation of 9 is included, but a general process can be applied, and the description thereof is omitted. In addition, the material wood 9 is held by one or both of the upstream side holding part 32 and the downstream side holding part 37 and fixed at a position where it can be processed in each process (step), or the joining member 10. , 20, and processing such as processing (process) for taking out the offcuts generated after cutting from the conveyance unit 31 are also partially omitted.

  Moreover, in the following description, among the outer peripheral surfaces (four side surfaces 9m, 9n, 9M, and 9N) of the material wood 9, the top of the conveying unit 31 when being put in and when the joining members 10 and 20 are completed. The surface facing the upper side in the vertical direction is the side surface 9N, the surface facing the lower side is the side surface 9n, the upstream side in the direction in which the material wood 9 is conveyed is the right side, and the downstream side is the left side. A description will be given assuming that the surface facing the near side is a side surface 9m.

  In the joining member processing, as shown in FIG. 4, first, the material wood reversing step S <b> 1 is performed. Specifically, the material wood 9 put into the wood processing apparatus 1 is rotated by the rotating unit 36 around the central axis in the longitudinal direction. As this rotation, 90 degree rotation is executed twice, and the lower surface supported by the transport unit 31 is changed from the side surface 9n to the side surface 9N, and the surface facing the front side is changed from the side surface 9m to the side surface 9M. Invert. As a result, the material wood 9 becomes a state in which the material wood 9 is reversed and turned upside down (in the state of FIG. 5A) with respect to the longitudinal direction as compared with the time of charging, and a part of the outer peripheral surface of the material wood 9 Cutting by the downstream side cutting portion 35 with respect to (side surfaces 9M, 9N) becomes possible.

  After the processing of the material wood reversing step S1, as shown in FIG. 4, the partial cutting step S2 for forming the rear end side joining portion 23 of the second joining member 20 is performed. In the partial cutting step S <b> 2, the material wood 9 is placed by the downstream holding portion 37 at a position where the downstream cutting portion 35 can process the position where the rear end side joining portion 23 of the second joining member 20 is to be formed. In the fixed state, as shown in FIGS. 5 (a) and 6 (a), the groove-shaped cutting on the side surface 9M and the groove-shaped cutting on the side surface 9N are performed by the downstream-side cutting unit 35. Is done. Thus, a side surface 23M forming one side surface of the rear end side joint portion 23 and a side surface 23N continuous with the one side surface are formed. As a result, a part 21B 'of the rear end surface 21B of the main body 21 is formed.

  After the process of the partial cutting process S2, the process of the partial cutting process S3 for forming the rear end side joining part 13 of the member 10 for 1st joining is performed, and the process similar to the partial cutting process S2 is performed. Specifically, the material wood 9 is fixed by the downstream holding portion 37 at a position where the downstream cutting portion 35 can process the position where the rear end side joining portion 13 of the first joining member 10 is to be formed. In the fixed state, as shown in FIGS. 5 (b) and 6 (a), the downstream cutting portion 35 performs groove-shaped cutting on the side surface 9M and groove-shaped cutting on the side surface 9N. Is called. Thus, a side surface 13M forming one side surface of the rear end side joining portion 13 and a side surface 13N continuous with the one side surface are formed. Thereby, a part 11B 'of the rear end surface 11B of the main body 11 is formed.

  In addition, when the rear end side joining portions 13 and 23 of the respective joining members 10 and 20 are partially formed, when the end portion on the front end side of the material wood 9 reaches the upstream holding portion 32, The material wood 9 may be fixed by both the upstream side holding part 32 and the downstream side holding part 37. Moreover, the order of the partial cutting steps S2 and S3 may be reversed.

  After the processing of the partial cutting step S3, the processing of the material wood inversion step S4 for rotating the material wood 9 by the rotating unit 36 is performed. Specifically, as shown in FIGS. 5 (c) and 6 (b), the material wood 9 is rotated around the central axis in the longitudinal direction by rotating 90 degrees twice and supported by the transport unit 31. The lower surface is reversed from the side surface 9N to the side surface 9n, and the surface facing the near side is reversed from the side surface 9M to the side surface 9m. As a result, the downstream side cutting portion 35 enables cutting on the side surface 9m side and cutting on the side surface 9n side, and all peripheral surfaces continuous in the longitudinal direction of the material wood 9 by the processing before and after the reversing step S4. Can be cut.

  Further, the material wood 9 that has been turned upside down by the reversing step S1 is reversed again by the reversing step S4, so that the material wood 9 is arranged in the same direction as at the time of charging. For this reason, the processing by the upstream side cutting portion 34 can be performed in the same direction as that at the time of charging. Therefore, the front end side joining portions 12 and 22 can be processed in the same direction as the processing of the wood (for example, the pillar material) that does not require the reversing step S1 to turn the material wood 9 upside down. This makes it easy to share programs.

  Further, even when a reference surface (for example, the upward side surface 9N at the time of loading) is set in advance from the outer peripheral surface of the material wood 9, it is used for joining in the same direction as at the time of loading by two reversing steps S1 and S4. Processing of the members 10 and 20 can proceed. For this reason, the direction of the reference plane in proceeding with the processing of the joining members 10 and 20 can be easily matched with other pillar materials. Accordingly, when printing is performed on the joining members 10 and 20 and other pillar materials, it is easy to print on the reference surface facing upward, or when processing the material when the material wood 9 is introduced in consideration of warpage. The orientation of the reference plane can be easily matched between the joining members 10 and 20 and the other column members, etc., and the processing accuracy can be easily improved.

  After the reversing step S4, the cutting step S5 is performed on the front end side of the first joining member 10. Specifically, as shown in FIG. 5 (d), the portion where the width in the central axis direction is “LD” with respect to the front end portion of the material wood 9 is cut and removed. Thereby, the front end surface 12F of the front end side joining portion 12 of the first joining member 10 is formed. The front end face 9F of the material wood 9 is preliminarily surfaced in parallel with the front end face 12F of the front end side joining portion 12, and the front end face 12F of the front end side joining portion 12 and the front end face 9F of the material wood 9 match. In this case, the cutting step S5 can be omitted.

  After the process of cutting process S5, the process of formation process S6 of the front end side junction part 12 of the member 10 for 1st joining is performed. Specifically, the state in which the material wood 9 is fixed by the downstream holding portion 37 at a position where the upstream cutting portion 34 can process the position where the front end side joining portion 12 of the first joining member 10 is to be formed. Then, as shown in FIGS. 5 (e) and 6 (c), the upstream side cutting portion 34 takes a side surface from the front end surface 12F side (the front end surface 9F side of the material wood 9) of the first joining member 10. 9m, side surface 9n, side surface 9M and side surface 9N are cut so as to circulate along the side surface 9N. By this formation step S6, the side surface 12m, the side surface 12n, the side surface 12M, and the side surface 12N that form the entire peripheral surface of the front end side joining portion 12 are sequentially formed. Further, the front end surface 11F of the main body 11 is formed by the forming step S6.

  Here, in the formation step S6, from the front end surface 9F side of the material wood 9, the tip portion of the cutting tool 34A of the upstream cutting portion 34 in order with respect to the side surfaces 9m, 9n, 9M, 9N of the material wood 9 ( Cutting is performed by bringing the blade part into contact. The blade portion of the cutting tool 34A moves linearly along each surface of the material wood 9, and then moves so as to go around while changing the traveling direction. In cutting by this rounding, if the width of the blade portion of the upstream side cutting portion 34 is shorter than the length LC of the front end side joining portion 12, processing along the movement in the longitudinal direction of the material wood 9 is performed, and the length LC Until it becomes, it repeats the cutting by the circumference.

  In addition, the cutting by the upstream side cutting portion 34 in the forming step S6 is performed at a position farthest from the fixed portion by the downstream holding portion 37, but is performed on the fixed portion side before this processed portion. In the cutting for the rear end side joint portions 13 and 23 of the respective joining members 10 and 20, by not cutting the side surfaces 13m, 13n, 23m and 23n of the rear end side joint portions 13 and 23, A decrease in strength and rigidity of the material wood 9 from the fixed place to the processed place is suppressed. For this reason, the front end side joining portion 12 can be formed by high-speed processing of a certain level or more without greatly reducing the processing accuracy. Furthermore, since the cutting tool 34A of the upstream side cutting portion 34 is configured such that the distance R4 from the rotation center axis to the location where the blade portion is provided is shorter than the distance R5 in the cutting tool 35A of the downstream side cutting portion 35, When forming the front end side joining portion 12, the position shift of the portion supporting the cutting tool 34A can be made smaller than when cutting by the downstream side cutting portion 35, and high processing accuracy is maintained even in high-speed cutting. Can do.

  After the forming step S6, the remaining portion cutting step S7 for the rear end side joining portion 13 of the first joining member 10 is performed. Specifically, in the same manner as in the partial cutting step S3, the downstream holding portion is located at a position where the downstream cutting portion 35 can process the position where the rear end side joining portion 13 of the first joining member 10 is to be formed. In the state where the material wood 9 is fixed by 37, the downstream cutting portion 35 performs the groove-shaped cutting on the side surface 9m and the groove-shaped cutting on the side surface 9n as shown in FIGS. 5 (f) and 6 (d). And done. Thus, a side surface 13m that forms one side surface of the rear end side joining portion 13 and a side surface 13n that is continuous with the one side surface are formed. In addition, the remaining portion of the rear end surface 11B of the main body 11 is thereby formed, and the entire rear end surface 11B is formed.

  After the remaining portion cutting step S7, the separation step S8 of the first joining member 10 is performed. Specifically, as shown in FIG. 5G, the cutting portion 33 can be processed with respect to the planned cutting position on the rear end surface 13B side of the rear end side joint portion 13 of the first joining member 10. In a state where the material wood 9 is fixed by the upstream side holding portion 32, the end portion on the rear end side of the rear end side joining portion 13 is cut so that the width in the central axis direction becomes “LE”. . As a result, the first joining member 10 is separated from the material wood 9, and the rear end surface 13B of the rear end side joining portion 13 of the first joining member 10 is formed and the first joining member 10 is manufactured. Is completed. In addition, you may make it complete manufacture of the member 10 for 1st joining by performing another process with respect to the member 10 for 1st joining after isolate | separating from the material timber 9 by isolation | separation process S8, for example, The manufacturing of the first joining member 10 may be completed by chamfering the corner portion of the rear end surface 13B of the rear end side joining portion 13.

  Here, the distance between the rear end surface 13B of the rear end side joint portion 13 and the front end surface 22F of the front end side joint portion 22 of the second joining member 20 is designed to be the same as the cutting white by the cutting portion 33, Along with the formation of the rear end surface 13B of the rear end side joint portion 13, the front end surface 22F of the front end side joint portion 22 is also formed. Note that it is not always necessary to form the front end surface 22F of the front end side joint portion 22 together with the formation of the rear end surface 13B of the rear end side joint portion 13, and the length of “LE” as the width in the central axis direction is not necessarily required. May be set longer than the cutting scissors by the cutting portion 33, and the front end face 22F of the front end side joining portion 22 may be formed by cutting off a part of the front end side by another cutting process thereafter.

  After the process of the separation step S8, the process of the formation step S9 of the front end side joined portion 22 of the second joining member 20 is performed. In the forming step S9, as shown in FIGS. 5 (h) and 6 (c), processing similar to the forming step S6 of the front end side joining portion 12 of the first joining member 10 is performed, and the upstream side cutting portion 34 is formed. The side surface 22m, the side surface 22n, the side surface 22M, and the side surface 22N that form the entire peripheral surface of the front end side joining portion 22 are formed in this order by cutting. Further, the front end face 21F of the main body portion 21 is formed by this forming step S9.

  After the forming step S9, the remaining cutting step S10 of the rear end side joining portion 23 of the second joining member 20 is performed. In the remaining cutting step S10, as shown in FIGS. 5 (i) and 6 (d), the same processing as the remaining cutting step S7 for the rear end side joining portion 13 of the first joining member 10 is performed, and the downstream cutting step S10 is performed downstream. By the cutting by the side cutting portion 35, a side surface 23m forming one side surface of the rear end side joint portion 23 and a side surface 23n continuous with the one side surface are formed. Further, the remaining portion of the rear end surface 21B of the main body portion 21 is formed by the remaining portion cutting step S10, and the entire rear end surface 21B is formed.

  After the remaining cutting step S10, the separation step S11 of the second bonding member 20 is performed. In the separation step S11, as shown in FIG. 5 (j), the same processing as the separation step S8 of the first joining member 10 is performed, and the second joining member 20 is cut from the material wood 9 by cutting by the cutting portion 33. And the manufacture of the second joining member 20 is completed. In addition, you may make it complete manufacture of the 2nd joining member 20 by performing another process with respect to the 2nd joining member 20 after isolate | separating from the material timber 9 by isolation | separation process S11.

  As described above, according to the wood processing apparatus 1 that performs processing by the joining member processing, in the cutting step S5 (or the separation step S8), the cutting portion 33 cuts the material wood 9 into a planar shape (first side) The upstream cutting portion 34 performs cutting in the forming step S6 (or forming step S9) to form the front end side joining portion 12 (or the front end side joining portion 22). For this reason, a wide working space can be generated on the side of the material wood 9 where the front end side joining portion 12 is formed. Therefore, it is possible to process the peripheral surface of the front end side joining portion 12 with high accuracy in a short time by the upstream side cutting portion 34 using the situation where this work space is wide.

  Further, the downstream side cutting portion 35 has at least a part of the processing of the peripheral surface of the rear end side joint portion 13 (or rear end side joint portion 23), and the upstream side cutting portion 34 has the front end side joint portion 12 (or front end side). This is performed after the processing in the forming step S6 (or forming step S9) for forming the joint portion 22). For this reason, at the time of the process which forms the front end side junction part 12 (or front end side junction part 22) by the upstream side cutting part 34, the rear end side junction part 13 (or rear end side joining by the downstream side cutting part 35). The unprocessed part of the part 23) that has not been cut is left in the material wood 9. Therefore, the freedom degree of the position holding the material timber 9 hold | maintained by the downstream holding | maintenance part 37 can be raised. For example, an unprocessed portion of the rear end side joining portion 13 can be used as a part of a portion for holding the material wood 9 by the downstream holding portion 37.

  In the forming step S6, the material wood 9 is held by the downstream holding portion 37 at a position farther away from the position where the peripheral surface of the rear end side joining portion 13 is located with respect to the processing position by the upstream cutting portion 34. Even so, by providing the unprocessed portion of the rear end side joining portion 13, the material wood 9 can have a certain level of high strength and rigidity. For this reason, while increasing the degree of freedom of the position where the material wood 9 is held by the downstream holding portion 37, the processing by the upstream cutting portion 34 can be easily performed with a certain degree of accuracy in a short time, and damage during the processing also occurs. Can be difficult.

  Moreover, the upstream side cutting part 34 (cutting tool 34A) is comprised by the blade part installed in the position close | similar to a rotation center axis | shaft compared with the downstream side cutting part 35 (cutting tool 35A). For this reason, it is possible to perform high-accuracy processing while keeping the positional deviation of the blade portion by cutting low while setting the cutting force generated in the blade portion high with respect to the rotational torque, and the front end side joining portions 12 and 22. When the peripheral surface is machined, the moving distance can be shortened, and high-precision machining can be easily realized in a short time. The setting of the processing speed can be realized by providing unprocessed portions of the rear end side joint portions 13 and 23 corresponding to the required size, for example, unprocessed portions of the rear end side joint portions 13 and 23. By setting a large amount, it is possible to perform a setting in which the upstream cutting portion 34 is processed in a short time with a certain level of accuracy.

  Further, the upstream side cutting portion 34 is divided into the downstream side before the cutting process for forming the peripheral surface of the front end side joining portion 12 (or the front end side joining portion 22) and after the cutting process is performed. Processing in which the peripheral surface of the rear end side joint portion 13 (or rear end side joint portion 23) is formed by the cutting portion 35 is performed. In this case, the direction which intersects with the longitudinal direction of the material wood 9 by the partial cutting steps S2 and S3 before the front end side joining portion 12 (or the front end side joining portion 22) is cut by the upstream side cutting portion 34. The rear end side joining portion 13 of the two joining members 10 and 20 with respect to the side where the downstream side cutting portion 35 is easily disposed (for example, the lower side and the near side of the material wood 9 in FIG. 5). Machining at a plurality of locations corresponding to 23 is performed collectively. After the rotation of the material wood 9 by the rotating part 36 in the reversing step S4, the downstream cutting part 35 arranges the processing of the unprocessed parts of the rear end side joining parts 13 and 23 in the joining members 10 and 20. It can be executed again from the easy side. Therefore, the rear end side joining portions 13 and 23 of the two joining members 10 and 20 can be efficiently processed while setting the moving range of the downstream side cutting portion 35 to be small. Thereby, about formation of the rear end side joining parts 13 and 23, it can employ | adopt combining the ease of the process according to the specification of the downstream side cutting part 35, and an efficient setting.

  Further, when the two joining members 10 and 20 are manufactured from the material wood 9, the rear end side joining portion 23 of the second joining member 20 different from the first joining member 10 produced previously is not yet formed. The material wood 9 with the processed portion remaining is cut by the cutting portion 33 in the separation step S8, and the rear end surface 13B of the rear end side connecting portion 13 of the first connecting member 10 is formed. For this reason, also in the cutting process of the rear end surface 13B of the rear end side joint part 13 by the cutting part 33 in the separation step S8, the material wood 9 can be processed with high strength and rigidity higher than a certain level, and the downstream side While increasing the degree of freedom of the holding position of the material wood 9 by the holding portion 37, the cutting portion 33 can be easily processed with high accuracy in a short time, and damage during the processing can be made difficult to occur.

In this case, each configuration described below is different from the above-described embodiment. You may apply and may apply with respect to the said embodiment combining the some structure described below.

  In the said embodiment, although the case where two joining members (joining members 10 and 20) are manufactured from one material wood 9 is demonstrated as a joining member processing process shown in FIG. In this case, various processes related to the second bonding member 20 (partial cutting process S2, forming process S9, remaining cutting process S10 and The separation step S11) may not be performed. In addition to the first joining member 10 and the second joining member 20, one or more other joining members may be manufactured from one material wood 9, and in this case, the first joining Prior to the formation step S6 of the front end side joining portion 12 of the member for welding 10, a partial cutting step for the rear end side joining portion of the other joining member is performed, and more than the separation step S11 of the second joining member 20 Later, it is good also as a structure which completes manufacture of the other joining member by repeating a series of processes similar to formation process S6-separation process S8 with respect to another joining member once or several times.

  Moreover, in the said embodiment, before the partial cutting process S3 for the rear end side joining part 13 of the 1st joining member 10, the partial cutting process S2 for the rear end side joining part 23 of the 2nd joining member 20 is carried out. However, the order of the partial cutting steps S2 and S3 of the rear end side joining portions 13 and 23 may be reversed, or three or more joining members are manufactured from the material wood 9. Moreover, the order of the partial cutting process with respect to each member for joining can be set suitably. However, when manufacturing three or more joining members from the material wood 9, the partial cutting process for the rear end side joining portion of each joining member is performed in the order from the one end side to the other end side of the material wood 9. It is preferable to reduce the amount of movement of the material wood 9 by the transport unit 31.

  Moreover, in the said embodiment, although it was set as the structure which the downstream cutting part 35 cuts the two side surfaces along the longitudinal direction of the material timber 9 in each partial cutting process S2, S3, it is good also as another structure. For example, only one side may be cut in the partial cutting step S2, and the remaining three sides may be cut in the remaining cutting steps S7 and S10. That is, prior to the formation of the front end side joint portion of each joining member, cutting may be performed so that a part of the peripheral surface of the rear end side joint portion of the joining member remains, A configuration may be adopted in which a part of the peripheral surface of the material wood 9 is left by performing a local cutting such as cutting a part of the side face partly without completely cutting one side face, or In addition, all of the cutting of the rear end side joining portion of the joining member may be performed after the front end side joining portion of the joining member is formed.

  In the above embodiment, the drive control device 3 reads the processing data of a plurality of (many) joining members acquired from the processing information processing device 4, and the plurality of joining members that can be processed from one material wood 9. It may be configured to include a program for selecting a combination, or may be configured to include a program that presents candidates for the combination to the worker through display on a display device and determines the execution of the task by the operator's determination operation. Moreover, it is good also as a structure containing the program which selects a combination so that a member for joining and a member different from a member for joining may be included as a member which can manufacture two or more from one material wood 9.
