Next, the turning control of the lower cutter 187 for cutting a corner block and cutting a valley in the horizontal member cutting and upper / lower surface processing machine 100 according to the present embodiment will be described. In the present embodiment, the air cylinders 191 to 193 provided for turning the lower cutter 187 are respectively 25 mm, 50 mm, and 7 mm as shown in the schematic diagram of FIG.
The one having a maximum stroke of 5 mm is employed. Then, as shown in FIG.
3 is stroked to the retreat end (entry end) (illustration (A)), and the air cylinder 191 having a stroke of 25 mm
Only the air cylinder 192 having a stroke of 50 mm, with only one being stroked to the forward end (out end) (illustration (B)).
Only the stroke to the forward end (illustrated (C)),
The state in which the air cylinder 191 with a 25 mm stroke and the air cylinder 193 with a 75 mm stroke are stroked to the forward end (illustration (D)), and all the air cylinders 1
The lower cutter 187 is designed to be able to be swiveled at 45-degree intervals by controlling the state in which the strokes 91 to 193 are moved toward the forward end (illustrated (E)). The lower cutter 187 is designed so that the intersection of the center line of the blade width and the center of rotation is the center of rotation.

As shown in FIGS. 9 (A), (C)-(E), no. 4 vice 114 and No. 4 5 vise 115
The auxiliary rollers 126, 126 attached to the lower cutter 187 are set in a state where the auxiliary rollers 126, 126 on the bearing portion 186 are tilted downward according to the turning position of the lower cutter 187.
The side is controlled to be in a state of being turned to the raised position.
This is because the wood W is supported by the auxiliary roller 126 as close to the processing position as possible while performing accurate processing while avoiding interference between the bearing portion 186 and the auxiliary roller 126.

Further, FIGS. 9A, 9D and 9
9C and FIG. 9E, the angle of the blade of the lower cutter 187 with respect to the center line of the wood W is the same, but the position of the bearing portion 186 is opposite. This corresponds to the formation of a notch groove such that one side of the notch width is deep and the other side is shallow as illustrated in FIG. I have. That is, for example, in FIG. 9A, the notch depth at the top of the figure is smaller than the notch depth at the bottom of the figure, and in FIG. 9D, conversely, the notch depth at the top of the figure is smaller. Shallower than the notch depth below. Therefore, by controlling the two kinds of turning positions shown in FIGS. 9 (A) and 9 (D), the bearing 186 is positioned on the shallower side of the notch, and the bearing 186 and the wood can be controlled. It is designed to be able to cut corners and valleys while avoiding interference with W. Here, in FIG. 9, an arrow marked obliquely on the surface of the wood W means that corner cutting or valley cutting in accordance with the roof gradient is performed so that the tip side becomes deeper.

By the combination of the strokes of the air cylinders 191 to 193, in addition to the turning positions shown in FIGS. 9A to 9D, the turning positions shown in FIGS. 10D and 10F can be obtained. The turning control of the lower cutter 187 can be performed. However, as the underside processing of the horizontal material,
Since it is sufficient to implement four types of rafter chipping, corner tree chipping, and valley chipping, in this embodiment, actual machining is performed by five types of turning position control shown in FIG.

Next, a control system in the horizontal member pre-cutting facility 10 of this embodiment will be described. As shown in FIG. 11, the horizontal member precutting equipment 10 has an overall control device 601 for controlling the entirety of the precutting equipment 10 and CAD / CAM data input for inputting CAD / CAM data to the overall control device 601. And an apparatus 602. The overall control device 601 is roughly divided into a cutting / upper / lower surface processing control device 611 corresponding to the horizontal member cutting / upper / lower surface processing machine 100 and a horizontal member side processing machine 20.
A side processing control device 612 corresponding to “0” and a wood opening processing control device 613 corresponding to the horizontal timber cutting machine 300 are provided. And the cutting / upper / lower surface processing control device 61
1 is to control the input of wood into the horizontal member cutting / upper / lower surface processing machine 100, the processing after processing, and the discharge to the next process. , Chain slasher 21, roller conveyors 31 to 3
3. Positioning unit 400 and pusher plate 71
And the like are to be controlled. Similarly, the side surface processing control device 612 also controls the horizontal member side surface processing machine 200, the chain slasher 22, the roller conveyors 34 to 36, the positioning unit 500, the pusher plate 72, and the like. Further, the kiguchi processing control device 613 includes:
Each device after the chain slasher 23 is controlled.

Next, the control of the cutting of the horizontal member and the processing of the upper and lower surfaces by the cutting / upper surface processing controller 611 will be described.

First, the control for cutting the tip of the inserted wood W will be described. This control is executed in a procedure as shown in FIG. 12, and the feeding of the wood W put on the roller conveyor 31 by the chain slasher 21 and the wood changing device 61 is executed (S110). This material feeding operation continues until the leading end of the wood W is detected by the optical sensor units 116 and 117 (S120). When the tip of the wood W is detected by the optical sensor units 116 and 117 (S120: YES), the material feeding operation by the roller conveyor 31 and the like is stopped (S130). In addition, wood W
At the time of cutting the tip, the positioning is normally performed as described above. However, when the tip is rough and the tip needs to be cut off long, the positioning of the tip is performed using the positioning unit 400. Sometimes.

Then, No. The one vise 111 and the upper surface clamper 123 are driven to clamp the wood W (S
140), the main shaft motor 135 of the cutting unit 130 is driven to start the rotation of the circular saw 132 (S150). After that, the hydraulic cylinder 134 is driven to rotate the arm 133 downward to perform the end cutting by the circular saw 132 (S1).
60). Then, the hydraulic cylinder 134 is driven again to rotate the arm 133 to the upper retreat position (S17).
0), the spindle motor 135 is stopped (S180), and the wood W
Is unclamped (S190). Thus, the tip of the inserted wood W is trimmed by trimming.

Next, positioning control by the positioning unit 400 will be described. In this control, as shown in FIG. 13, during the above-described trimming, the positioning unit 400 is moved to the forward end near the cutting position to set an initial position for starting material feeding (S210). . next,
The roller conveyor 31 and the like are driven to start feeding wood (S220). When one of the two reflection-type optical sensors provided at the tip of the positioning rod 413 of the positioning unit 400 detects that the tip of the wood W has reached a position near a predetermined distance from the tip of the positioning rod 413. (S230), the servo motor M2 is driven to start the movement of the positioning unit 400 (S24).
0). At this time, the moving speed of the positioning unit 400 is set slightly lower than the feed speed of the roller conveyor 31 and the like. Accordingly, the wood W is appropriately pressed against the tip of the positioning rod 413, and is transported in a state where the tip position is firmly defined.

Then, according to the contents of the CAD / CAM data, the transfer of the wood by the positioning unit 400 and the roller conveyor 31 is stopped so that the processing portion stops at the processing position by the cutting unit 130, the corner only unit 150 or the cutter unit 170. And a clamp operation by a vise or the like near the processing position is executed (S245). In addition,
Here, more specifically, the positioning unit 400 is moved to a predetermined position in accordance with CAD / CAM data and stopped, and in that state, the roller conveyor is rotated at a low speed, and the contact state described above is detected. Control is performed such that after confirming that the optical sensor is turned on, the transport operation of the roller conveyor is stopped, and clamping by a vice or the like is performed. When the processing at the position is completed (S250: YES), the presence or absence of the next processing part is confirmed (S260), the wood is unclamped, and the positioning unit 400 and the roller conveyor 31 are driven again to turn the wood W The intermittent feed in which the machining part is moved to the corresponding machining position and stopped is executed, and the process returns to S250 (S270). When all the processing on the wood W is completed (S260: NO), the air cylinder 415 of the positioning unit 400 is driven to retract the positioning rod 413 upward, and the positioning unit 400 is moved to the initial position again. Preparation for the next processing is performed (S280). Further, as described above, after detecting the state in which the wood W is completely unloaded from the processing machine 200, the air cylinders 74, 74 are driven to drive the wood W
The downstream chain slasher 2 with the pusher plate 71
2 (S290). In response to the completion signal of the lateral movement, driving of the chain slasher 22 and the like by the side surface processing control device 612 are started, and the control related to the next step, ie, the side surface operation of the horizontal member is started. Note that the above-described clamping and unclamping operations correspond to clamping and unclamping operations at the time of machining in the unit 150 and the like only for the corners described below.

Next, the contents of control such as mortise processing by the corner-only unit 150 will be described. In this control, as shown in FIG. No. 2 vice 112, No. 3 vise 113 and corresponding upper surface clamper 123,
The lumber W is clamped by driving 123 (S310).
Next, the servo motors M11 and M12 are drive-controlled to align the processing center of the corner 158 or the drill 160 to the processing position in the X-axis direction and the Z-axis direction (S320), and drive the corner-only drive motor 159 (S320). (S330), the hydraulic cylinder 163 is driven to move only the corner 158 toward the wood W in the Y-axis direction (S340).

Here, the wood W is placed on the roller conveyor such that the upper surface as the actual horizontal member is the lower surface. Further, the lower surface of the wood W is fixed at a certain height depending on the height of the roller. Therefore, when performing mortise processing on the lower surface of the wood W in the control of S340, the tip of only the lower corner 158 is raised from the roller upper surface by the height corresponding to the mortise depth determined by the processing data. The hydraulic cylinder 163 is caused to execute a stroke motion to the position. On the other hand, in mortise processing on the upper surface of the wood W, a sliding rod (not shown) provided only near the upper corner 158 hits the upper surface of the wood W and stops. When the detection fitting attached to the upper end of the moving rod is detected by the proximity sensor, it is controlled that the stroke movement of the hydraulic cylinder 163 is stopped, assuming that the mortise processing of the predetermined depth is completed.

Thus, only the corner 158 or the drill 160
When the mortise or drill hole is machined to a predetermined depth (S350: YES), the hydraulic cylinder 163 is driven in the opposite direction to retract only the corner 158 in the Y-axis direction (S3).
60). Then, it is determined whether or not it is necessary to move the unit 150 in the X-axis direction only at a corner with respect to this machined portion to perform the next hole machining, such as an axial long mortise (S370). If necessary, the servo motor M11 is driven to move only the angle 158 in the X-axis direction (S380), and the control of S340 and subsequent steps is performed again. If it is determined that the processing of the mortise or drill hole in the processing part has been completed (S370: NO), the servomotors M11 and M12
Is driven to return to the origin position, the drive motor 159 is stopped only at the corners, and the wood W is unclamped (S390).

Next, the details of the control of the lower stud notch processing by the cutter unit 170 will be described. In this control, as shown in FIG. 4 vice 114,
No. The wood W is clamped by the five vise 115 and the corresponding upper surface clampers 123, 123 (S
410). Next, air cylinders 191 to 193 for turning are used.
Is driven so as to be in the state shown in FIG. 9B, and the lower cutter 187 is turned so as to be orthogonal to the center line of the wood W (S420). When the lower cutter 187 is initially in the state shown in FIG.
The control of 420 is omitted.

Subsequently, the lower cutter 187 is moved to the machining start position in the X-axis direction and the Z-axis direction by driving the servo motors M22 and M24 (S430). Then, while driving the lower cutter motor 185 (S440),
By driving the servo motor M23, the lower cutter 187 is moved in the Y-axis direction to a position above the roller surface by a height corresponding to the stud notch depth (S450). Thereafter, the servomotor M24 is further driven to move the lower cutter 187 in the Z-axis direction (S45).
5) A stud notch is formed in the width direction of the wood W.

Thereafter, the servo motor M23 is driven to drive Y
The lower cutter 187 is retracted in the axial direction (S460),
It is determined from the CAD / CAM data whether a larger notch width is required (S470). If a larger notch width is required (S470: YES), the servo motor M22 is driven to move the lower cutter 187 in the X-axis direction by a predetermined amount (S480), and the control in and after S450 is repeatedly executed. . Then, when the stud notch of the required width can be machined (S470: NO), the lower cutter motor 185 is stopped (S490), and the origin return of the lower cutter 187 and unclamping of the wood W are executed (S49).
5).

Next, the control contents of the upper stud notch processing by the cutter unit 170 will be described. In this control, as shown in FIG. 16, first, the wood W is clamped as in the case of the lower stud notch processing (S510). Next, the servomotor M22 and the hydraulic cylinder CL22 are driven to move the upper cutter 180 to the processing start position in the X-axis direction and the Z-axis direction (S520). Then, while driving the upper cutter motor 179 (S530), the hydraulic cylinder CL21 is driven to move the upper cutter 18 in the Y-axis direction.
0 is decreased (S540). In the control of S540, similarly to the case of the upper surface processing by the corner only unit 150, necessary processing is performed by using a sliding rod provided near the upper cutter 180, a proximity sensor (both not shown), and the like. It is configured to detect that the upper cutter 180 has been lowered to the depth. Thereafter, the hydraulic cylinder CL2
2 is driven to move the upper cutter 180 in the Z-axis direction (S550) to form stud notches in the width direction of the wood W.

Then, the hydraulic cylinder CL21 is driven to retract the upper cutter 180 in the Y-axis direction (S56).
0), when a larger notch width is required (S570:
YES), after driving the servo motor M22 to move the upper cutter 180 by a predetermined amount in the X-axis direction (S580),
The control of S540 and subsequent steps is repeatedly executed. Then, when the stud notch having the required width can be machined (S570: NO), the upper cutter motor 179 is stopped (59).
0), the origin return of the upper cutter 180 and the unclamping of the wood W are executed (S595).

Next, the contents of control of the rafter chipping process by the cutter unit 170 will be described. In this control,
As shown in FIG. 17, as in the case of the lower stud notch processing, the operation of clamping the wood W and the operation of turning the lower cutter 187 to be orthogonal to the center line of the wood W are executed (S610, S620). . Again, the lower cutter 18
When 7 is initially in the state shown in FIG. 9B, the control of S620 is omitted.

Then, the lower cutter 187 is moved to the machining start position in the X-axis direction and the Z-axis direction by driving the servo motors M22 and M24 (S630). Then, while driving the lower cutter motor 185 (S640),
Drive the lower motor 187 by driving the servo motor M23
By moving in the axial direction, the side cut is performed to the required depth on the side of the eaves girder without the rafters (S65).
0). Then, according to the roof slope, the lower cutter 18
By driving the servomotors M23 and M24 together so as to control the positions in the Y-axis and Z-axis directions so as to move the 7 obliquely in the YZ plane, a rafter chip having an inclined surface corresponding to the roof gradient is cut. (S655).

Thereafter, the servo motor M23 is driven to drive Y
The lower cutter 187 is retracted in the axial direction (S660),
If a larger notch width is required (S670: YE
S) After driving the servo motor M22 to move the lower cutter 187 in the X-axis direction by a predetermined amount (S680),
The control of 50 or less is repeatedly executed. Then, when the rafter chip of the required width can be machined (S670: NO), the lower cutter motor 185 is stopped (S690),
The origin return of the lower cutter 187 and the unclamping of the wood W are executed (S695).

Next, a description will be given of the control contents of the corner chipping and valley chipping processing by the cutter unit 170. In this control, as shown in FIG. 18, similarly to the case of the lower stud notch processing, after performing the wood W clamping operation (S71).
0), and the lower air cutters 187 are turned so that the lower cutter 187 is in one of the states shown in FIGS. 9A and 9C to 9E based on the processing direction of the corner cut or the valley cut.
3 is driven and turned (S720). And FIG.
As shown in (A), (C) to (E), the bearing portion 186
The auxiliary roller 126 on the side is lowered to the lowered position (S725).
In the case of the lower stud notch and the rafter chip, both the front and rear auxiliary rollers 126, 126 were kept at the raised position. However, in the corner chip cutting and the valley chip cutting, only one of them was set at the raised position. The control contents are different. This is because the auxiliary roller 126 does not interfere with the bearing 186 when machining the corner and valley notches.
This is because it is necessary to retreat the auxiliary roller 126 on the side with 6 to the lowered position.

Subsequently, the servomotors M22 and M24 are driven to move the lower cutter 187 in the X-axis direction and the Z-axis direction to the machining start position on the XZ plane (S730). Then, the lower cutter motor 185 is driven (S740), and the servomotor M23 is driven to raise the lower cutter 187 in the Y-axis direction to execute cutting to the cutting depth at the cutting start position (S750). . Thereafter, the servo motors M23 and M24 are driven in accordance with the roof gradient, and the lower cutter 18 is driven.
By driving the servo motor M22 in accordance with the turning angle of the lower cutter 187 in the XYZ three-axis directions.
Is cut in a corner cut or a valley cut for a cutter width having a slope matching the roof slope and extending in a direction matching the blade width center line of the lower cutter 187 while complementarily moving (S755). .

Thereafter, the servo motor M23 is driven to drive Y
The lower cutter 187 is retracted in the axial direction (S760),
If a larger notch width is required (S770: YE
S) After driving the servomotor M22 to move the lower cutter 187 by a predetermined amount in the X-axis direction (S780),
The control of 50 or less is repeatedly executed. Then, if a corner cut or a valley cut with a required width can be machined (S770: N
O), the lower cutter motor 185 is stopped (S790), and the origin return of the lower cutter 187 and unclamping of the wood W are executed (S795).

According to the horizontal member cutting / upper / lower surface processing machine 100 employed in the present embodiment, the above-described configuration is employed, and the above-described control processing is executed.
As shown in the figure, mortise (illustration (A)), bolt hole (illustration (B)), stud notch (illustration (C)), rafter chipping (illustration (D)), corner cut or trough A notch (illustration (E)) can be formed. In addition, as the stud notch, a half stud notch can be processed up to a half width of the transverse member as shown in FIG. In the processing of the stud notch, if both the upper surface and the lower surface of the horizontal member are processed at the same position in the X-axis direction, the above-described processing of the upper stud notch and the processing of the lower stud notch are performed. May be executed simultaneously. If the position in the X-axis direction is the same, the rafter processing may be performed on the lower surface of the horizontal member while the upper stud notch processing is being performed.

As described above, according to the present embodiment, there is no need to install a dedicated corner-cutting machine at the final stage of the pre-cutting member for horizontal members 10, thereby reducing equipment costs and effectively utilizing factory space. And can be achieved. In addition, corner cuts and valley cuts can be machined into the horizontal member as necessary based on CAD / CAM data by automatic control, so that forgetting to work can be prevented.

Further, the horizontal member upper and lower surface processing machine 1 of the embodiment
In 00, since the position control of the lower cutter 187 in the X-axis, Y-axis, and Z-axis directions is performed by the servo motor M22 and the like, corner cuts and trough cuts can be formed with high accuracy. Note that the position control of the upper cutter 180 in the Y-axis and Z-axis directions is performed by the hydraulic cylinders CL21 and CL22. Not enough.

Further, the horizontal member upper and lower surface processing machine 100 according to the embodiment employs a configuration in which the lower cutter 187 is turned around the intersection of the blade width center line and the rotation center line, and each vise 111 Since 115 to 115 are configured to clamp the horizontal member while centering it on the roller conveyor, it is easy to control the processing start position at the time of cutting a corner cut or a valley cut and to set the turning range of the lower cutter 187 to be small. The configuration can be minimized, which is advantageous for miniaturization of the apparatus.

In addition, the horizontal member upper and lower surface processing machine 100 according to the embodiment uses three air cylinders 191 to 193 to combine the stroke operations of the air cylinders 191 to 193 to the forward end and the backward end. Therefore, since the lower cutter 187 is turned within a range of 270 degrees at 45-degree intervals, the control accuracy is high even though the turning angle is controlled by an air cylinder. In addition, as a result that the lower cutter can be turned within the entire range of 270 degrees, machining can be performed by positioning the bearing portion 186 of the lower cutter 187 in the shallower part of the corner chip or the valley chip. Corner chips and valley chips can be formed while avoiding interference between the portion 186 and the horizontal member. As a result, the lower cutter 1
A corner chip or a valley chip with a large depth can be formed without using a large diameter member as the 87, which is advantageous in miniaturizing the apparatus.

In addition, No. 4 vice 114 and No. 4 5
The vice 115 is provided with foldable auxiliary rollers 126, 126. When a corner or a valley is missing, a bearing 186 is provided.
The configuration in which the processing is performed by tilting the auxiliary roller 126 on the side downward is adopted, so that interference with the bearing portion 186 is avoided.
The lower surface of the horizontal member can be supported as close to the lower cutter 187 as possible, which is advantageous for improving processing accuracy. In addition, when the corner chipping and the valley chipping are not performed, the auxiliary rollers 126, 126 are raised so that the No. No. 4 vice 114 and no. The support interval of the horizontal member by the five vise 115 can be shortened, and the configuration does not hinder the conveyance of the short horizontal member such as a small beam.

Further, according to the pre-cutting equipment of the present embodiment, the chain slashers 22 and the like downstream of the horizontal member upper and lower surface processing machine 100 are constituted by two rows of chains, respectively.
Since corner cuts and trough cuts are prevented from getting stuck in the chain, even if corner cuts and trough cuts are formed by upper and lower surface processing, it will not interfere with the lateral movement of the horizontal members in the subsequent process There is no.

Further, since the horizontal member upper and lower surface processing machine 100 employs a configuration in which a drill shaft 161 is provided in addition to the corner only unit 150 so that a drill hole can also be formed, a post-process is performed. It is not necessary to perform drilling on the lower surface. As a result, there is also an effect that it is not necessary to provide a dedicated drilling machine in a post-process.

Further, the pre-cut equipment 1 of the present embodiment
According to No. 0, by adopting a configuration in which the processing of the upper and lower surfaces and the processing of the side surface of the horizontal member are performed by separate processing machines 100 and 200, the horizontal member is processed by the respective processing machines 100 and 200 for processing. The stagnation time is shortened, and in this type of equipment, the transverse member can be rapidly processed in each of the processing machines 100 and 200 one after another using the transfer time that is inevitably generated. Significantly improved.

In addition, the pre-cut equipment 1 of the present embodiment
According to No. 0, by constructing the woodcutting machine 300 as described above, the transverse member having finished the woodcut at one end before using the transport time of the wood that has been woodcut at one end. Of the other end of the equipment can be executed, thereby also greatly improving the processing efficiency of the entire equipment.

The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and may be embodied in various other forms without departing from the gist of the present invention. it can.
