Description

  The present invention relates to a wood precut processing machine, and more particularly, to a precut processing machine suitable for tenon processing of both ends of a pillar material.

  The column member of the wooden house is provided with a lower tenon on the lower end side and an upper tenon on the upper end side for joining with the upper and lower horizontal members. For this reason, conventionally, in the mortise processing unit of the columnar material processing machine, a cutting tool in which a mortise cutter and a chamfer cutter are integrated is attached to both ends of the main shaft of the mortise motor (Patent Document 1). The knives are chamfered and chamfered at the tip of the mortise at the same time.

  Here, the processing length of the tenon is determined by the positional relationship between the tenon cutter and the chamfering cutter on the cutter mounted on the spindle. For this reason, in the conventional processing machine, the tenon length could not be changed without replacing the blade.

For this reason, a tenon processing apparatus for a column material that can process the lower tenon of various lengths without replacing the processing blade has been proposed (Patent Document 2). As shown in FIG. 18, the lower tenon processing apparatus disclosed in Patent Document 2 has a main shaft A of a tenon processing motor and a large-diameter processing blade B and a small-diameter processing blade C that are coaxially combined. A cutter is attached, and a chamfering blade D is formed at the joint portion between the large-diameter machining blade B and the small-diameter machining blade C. Then, as shown in FIG. 18 (A), after machining with the small-diameter machining blade C and the chamfering blade D, the lower tenon of the lower tenon is cut by grinding with the large-diameter machining blade B as shown in FIG. 18 (B). The length is changed.
Japanese Patent Publication No. 1-55963 (column 8, lines 20-35, Fig. 3) JP 2003-236802 (paragraph 0009, FIGS. 4 and 5)

  In the apparatus of Patent Document 1, there is a problem that the blade needs to be replaced in order to change the length of the tenon.

  In the device of Patent Document 2, the length of the tenon can be changed without exchanging the blade, but the position of the small-diameter machining blade C and the large-diameter machining blade B is changed by moving the main shaft in the horizontal direction during the tenon machining. This is a two-stage cutting operation, and this must be performed on both sides of the tenon. Therefore, it is necessary to move the spindle up and down four times, and there is a problem that it takes time for the machining.

  Accordingly, an object of the present invention is to enable machining of tenons of various lengths without requiring blade replacement and without increasing the processing time.

In order to achieve the above object, a columnar pre-cut processing machine according to the present invention comprises at least one end of a main shaft of a tenon main shaft motor whose position can be controlled at least in the front-rear and vertical directions, and a tenon cutting cutter that is rotationally driven by the main shaft. A tenon chamfering cutter is mounted, and the tenon machining is performed on the end face of the wood fixed at the tenon machining position by performing drive control and position control of the tenon spindle motor based on the machining data. Further, the present invention has the following configuration.
(0) An end face finishing cutter that is rotationally driven by the main shaft is also attached to the one end of the main shaft of the tenon processing main shaft motor.
(1) The tenon tip chamfering cutter and the end surface finishing cutter are attached to the main shaft so as to be movable in the axial direction and receive transmission of a rotational force.
(2) A moving mechanism for moving the tenon tip chamfering cutter and the end face finishing cutter in the axial direction is provided.
(3) A tenon length changing servo motor for driving and controlling the moving mechanism is provided.
(4) Provided with a tenon length change control device that drives and controls the tenon length changing servo motor prior to tenon machining and changes the axial position of the tenon chamfering cutter according to machining data.

According to the column material precut processing machine of the present invention, the tenon length change control device moves the tenon tip chamfering cutter in the axial direction prior to tenon machining, and the tenon cutting cutter, the tenon tip chamfering cutter, and the end surface finishing cutter . The positional relationship is changed so that a tenon having a length corresponding to the processing data can be processed. As a result, according to the pillar material pre-cutter processing machine of the present invention, tenons of various lengths can be processed without exchanging blades or increasing the number of processing steps.

  The configuration (1) can be specifically realized by fitting the tenon chamfering cutter to the main shaft by key coupling or spline coupling. For example, the moving mechanism may be configured such that the moving body to which the tenon chamfering cutter is fixed is a mechanism capable of axial feeding such as a screw feeding mechanism or a rack and pinion mechanism.

Here, the pillar material precut processing machine of the present invention can further have the following configuration.
(5) A tenon cutting cutter and a tenon tip chamfering cutter that are rotationally driven by the main shaft are attached to the other end of the main shaft of the tenon processing main shaft motor.
(6) The moving mechanism is configured to move in conjunction with a tenon chamfering cutter attached to the other end of the main shaft .

  By providing the configurations of (5) and (6), both the lower tenon and the upper tenon can be processed in the middle of moving the conveying line in the axial direction without reversing the wood. At this time, the lower tenon and the upper tenon of various lengths can be processed by causing the control device to execute the tenon length change control prior to the tenon processing, as described above. In addition, since the moving mechanism is configured as described in (6) above, it is possible to change the length of the lower tenon and the upper tenon without providing a plurality of tenon length changing servomotors. In addition, since the lower tenon and the upper tenon are not processed at the same time, and the wood is transported and fixed between the lower tenon processing and the upper tenon processing, by executing the tenon length change control during that time, There is no delay in processing time due to the interlocking.

  Here, as a specific example of the configuration for moving the tenon chamfering cutter in conjunction with each other, for example, a moving body that fixes the tenon chamfering cutter to both ends, and a screw feed mechanism or a rack and pinion mechanism that moves the moving body in the axial direction. And so on.

  According to the present invention, tenons having various lengths can be machined without the need to replace the blade and lengthening the machining time.

  Embodiments of the present invention will be described below with reference to the drawings. The embodiment relates to a pillar material precut processing machine. As shown in FIGS. 1 and 2, the column material precut processing machine 1 is roughly composed of an input conveyor unit 100, a processing machine main body unit 300, and a take-out conveyor unit 900.

  As shown in FIGS. 1 and 2, the input conveyor unit 100 includes a material stock conveyor 110, a transfer body 120, an input conveyor 130, and a remaining material take-out device 140.

  The material stock conveyor 110 includes a plurality of rows of wheel conveyors that are inclined so that the input conveyor 130 side is lowered. Further, the material stock conveyor 110 has a lower discharge side (input conveyor side) than the roller surface of the input conveyor 130. Therefore, the processed material is conveyed to the front position of the roller conveyor 130 by the material stock conveyor 110 and is stocked in a state of being pressed against a stopper installed in front of the roller conveyor 130.

  The transfer body 120 is configured such that the main body can be moved up and down and moved back and forth, and the lifted portion is moved back and forth by three air cylinders. This forward / backward position shift operation is an operation for moving the lifted portion to a standby state at one of the two-stage positions of a workpiece having a large width and a small width. Before the workpiece is charged, the transfer body 120 waits in a state where it is shifted back and forth in accordance with the width of the workpiece at the lower portion of the workpiece supplied to the stopper contact position in front of the roller conveyor 130 by the material loading conveyor 110. It will be in the state. Then, when a workpiece input command is input, the main body is lifted to lift the workpiece from the material stock conveyor 110, and then the main body is moved forward to place the workpiece above the input conveyor 130. The workpiece is supplied onto the input conveyor 130 by lowering the main body after the movement. When this supply operation is completed, the main body is moved back and forth to return to the standby position. When the leading workpiece is lifted by the operation of this transfer body, the next workpiece is moved to the leading position due to the inclination of the material stock conveyor 110.

  Next, the structural details of the surface processing units 600A and 600B will be described. The front surface processing unit 600A and the back surface processing unit 600B have the same structure except for the direction facing the surface processing position. In the following description, the front surface processing unit 600A will be described. explain.

  As shown in FIGS. 3 and 4, in the surface processing unit 600A, the first router shaft 611, the second router shaft 612, the counterbore drill shaft 613, and the scissor cutter shaft 614 are respectively moved forward and backward by the first router shaft. 621, second router shaft longitudinal movement base 622, counterbore drill shaft longitudinal movement base 623, and scissor cutter shaft longitudinal movement base 624. Each of these back-and-forth motion bases 621 to 624 is guided by a right rail 632 provided to extend in the front-rear direction on the right side of the lifting body 631 in the figure. The forward / backward movement bases 621 to 624 are respectively configured to move the first router shaft selection air cylinder 641, the second router shaft selection air cylinder 642, the counterbore drill shaft selection air cylinder 643, and the forward cutter shaft selection air cylinder 644. It moves back and forth along the right rail 632 by the backward movement. Thereby, the cutter used for surface processing is selected.

  A left rail 633 extending in the front-rear direction is also provided on the left surface of the lift 631 in the figure. A front and rear moving body 651 is attached to the left rail 633 so as to be movable back and forth. The forward / backward moving body 651 is configured such that the forward / backward movement is controlled by rotationally controlling a screw feed mechanism constituted by a forward / backward movement internal thread 652 and a forward / backward movement external thread 653 by a forward / backward movement servomotor 654.

  The end portions of the above-described back-and-forth motion bases 621 to 624 come into contact with the back-and-forth moving body 651 in the forward direction. That is, the forward / backward moving body 651 prevents the forward / backward movement bases 621 to 624 from moving forward. As a result, even if the forward / backward movement bases 621 to 624 are advanced by the forward movement of the axis selection air cylinders 641 to 644, the forward movement is restricted by the forward / backward moving body 651. Are controlled in the same way. Even if the forward movement of the shaft selection air cylinders 641 to 644 continues, the longitudinal movement bases 621 to 624 are pushed back if the longitudinal movement body 651 moves backward. Note that the back and forth movement of each of the longitudinally moving bases 621 to 624 due to the backward movement of the axis selection air cylinders 641 to 644 is not restricted by the forward and backward moving body 651.

  As a result, when one of the shaft selection air cylinders 641 to 644 is moved forward to select a blade necessary for a certain process, the longitudinal movement base corresponding to the air cylinder moves forward, and the longitudinal movement body 651 is moved forward. Stops in contact with. All but the air cylinder are set in the retracted state.

  The elevating body 631 is guided by an elevating body rail 662 provided in the column 661 so that it can be moved up and down. This lifting operation is controlled by a lifting servo motor 663. The column 661 is guided by a main body base upper rail 672 on the main body base 671 and can move in the left-right direction (longitudinal direction of the workpiece). This lateral movement is controlled by a lateral movement servomotor 673. The lifting servomotor 663 is configured to lift and lower the lifting body 631 by a screw feed mechanism. Also, the left / right servo motor 673 is configured to move the column 661 left and right by a screw feed mechanism.

  At the time of processing, the main shaft necessary for processing is rotated, and the longitudinal movement bases 621 to 624 to which the main shafts 611 to 614 are attached are moved forward by moving any of the axis selection air cylinders 641 to 644 forward and backward moving body 651. The vertical movement servomotor 663 controls the vertical movement while the horizontal movement servomotor 673 controls the horizontal movement, and the workpiece is fixed or transferred. The side is processed in the state.

  The control device provided in the processing machine 1 executes the following control processing for adjusting the processing timing in the control of the surface processing unit. The processing data includes information on the length of the column, the processing site, and the processing shape. As shown in FIG. 14, the control device converts the input processing data into control data for controlling each part of the processing machine 1. In this data conversion process, it is determined whether or not data for forming a through hole by drilling is included in the processing data (S10). If included (S10: YES), the front side surface is determined. Drive control data for forming a hole up to the center part of the material width is generated by the processing unit 600A (S20), and drive control data for forming a hole up to the center part of the material width by the back side surface processing unit 600B. Is generated (S30). Next, drive control data is generated for other machining data (S40). Then, in the drive control data generated in this way, it is determined whether or not there is drive control data for performing machining on two faces facing the same machining portion of the column (S50). When there is drive control data for carrying out machining on the two surfaces facing each other (S50: YES), it is determined whether or not the machining depth based on the drive control data causes interference of the cutter (S60). The drive control data generated in S20 and S30 described above corresponds to data that causes blade interference. When there is data that causes blade interference (S60: YES), these drive control data are processed so that the machining by one drive control data is completed and the machining by the other drive control data is started. Data for regulating the timing is set (S70). On the other hand, even if there is drive control data for instructing processing of two surfaces facing each other (S50: YES), if they do not cause the interference of the blade (S60: NO), these drive control data are the same. Data for matching the execution timing is set so as to process at the time (S80).

  By executing the processing as described above in the control device, according to the present processing machine 1, when the cutting tool interferes, the front surface processing unit 600A and the back surface processing unit 600B perform the same processing. In contrast, when there is no blade interference, the front side surface processing unit 600A and the back side surface processing unit 600B are controlled to execute the processing operation almost simultaneously. The

  As a result, according to this processing machine 1, while performing efficient processing by the facing surface processing machines 600A and 600B, it is possible to prevent damage to the cutter due to interference, generation of processing defects, and reduction in processing accuracy. be able to. Further, since the through holes are processed from two surfaces by the surface processing units 600A and 600B arranged to face each other, generation of burrs at the outlets of the through holes can be prevented. Furthermore, though it was decided to form a through-hole by processing from two surfaces, the surface processing machines 600A and 600B are arranged facing each other, so there is no need to roll over the workpiece, and the workpiece clamp is not released midway. In addition, since the processing by both units 600A and 600B can be performed, the position of the through hole does not shift.

  Next, details of the tenon processing unit 700 will be described.

  As shown in FIGS. 7 to 9, a lower tenon cutting cutter 721 is attached to the end of the lower tenon main shaft 801 of the tenon removing shaft motor 711, and the lower tenon tip chamfering cutter 722 is attached to the lower tenon side cutter flange 803. And an end face finishing cutter 723 are attached. Here, the lower tenon side cutter flange 803 is fitted to the lower tenon side main shaft 801 of the tenon removing shaft motor 711. In this fitted state, the lower tenon side cutter flange 803 is movable in the axial direction with respect to the lower tenon side main shaft 801, and the lower tenon side cutter flange 803 is rotated together with the lower tenon side main shaft 801 by the key 805. Has been made. The lower tenon side bearing case 807 receives the lower tenon side cutter flange 803 via the bearing 809. As a result, the lower tenon tip chamfering cutter 722 and the end surface finishing cutter 723 can move along the lower tenon side main shaft 801 to change the axial position of the lower tenon cutting cutter 721.

  An upper tenon cutting cutter 731 is attached to the end of the upper tenon side main shaft 811 of the tenon removing shaft motor 711, and the upper tenon side cutter flange 813 is provided with an upper tenon tip chamfering cutter 732 and a cutter 733 for the peripheral edge. It is attached. Here, similarly to the lower tenon side cutter flange 803, the upper tenon side cutter flange 813 is moved to the upper tenon side main shaft 811 of the tenon removal shaft motor 711 by the key 815 so that it can move in the axial direction and rotates together with the shaft. Mated by key connection. The upper tenon side bearing case 817 receives the upper tenon side cutter flange 813 via the bearing 819. As a result, the upper tenon tip chamfering cutter 732 and the holding / rotating edge cutter 733 can be rotated by the tenon removing shaft motor 711 and the axial position of the upper tenon cutting cutter 731 can be changed.

  Axial positional relationship between the upper tenon chamfering cutter 732 and the holding / rotating edge cutter 733 and the upper tenon cutting cutter 731, and an axial position between the lower tenon chamfering cutter 722 and the end surface finishing cutter 723 and the lower tenon cutting cutter 721. The relationship is adjusted by the tenon length changing body 831.

  The tenon length changing moving body 831 is guided by a rail (not shown) of the elevating body 841 and can move in the left-right direction. Both ends of the tenon length changing moving body 831 are integrally connected to the lower tenon side bearing case 807 and the upper tenon side bearing case 817. The tenon length changing moving body 831 moves left and right by driving and controlling a screw feed mechanism constituted by the female screw 832 and the male screw 833 by a tenon length changing servo motor 835. Depending on the left / right operation position of the tenon length changing body 831, the axial position of the upper tenon chamfering cutter 732 and the upper tenon cutting cutter 731 and the axial position of the lower tenon tip chamfering cutter 722 and the lower tenon cutting cutter 721 are servoed. By adjusting by control by the motor 835, according to this processing machine 1, the processing length of a lower tenon and an upper tenon can be changed arbitrarily.

  The elevating body 841 is guided by the rail 843 of the column 842 and is configured to be movable in the vertical direction. The elevating body 841 is controlled to move up and down by controlling a screw feeding mechanism constituted by an elevating female screw 844 and an elevating male screw 845 by an elevating servo motor 846. In addition, the column 842 is configured to be guided by a rail 852 on the left-right moving base 851 and move in the front-rear direction. The column 842 is controlled to move back and forth by controlling a screw feed mechanism constituted by a forward and backward movement internal thread 854 and a forward and backward movement external thread 855 by a longitudinal movement servomotor 856. Further, the left / right moving base 851 is configured to be guided by a rail 862 on the bed 861 so as to move in the left / right direction. The left-right movement base 851 is controlled in the left-right movement by controlling a screw feed mechanism constituted by a left-right movement female screw 864 and a left-right movement male screw 865 by a left-right movement servomotor 866.

  The cutters 721 to 723 and 731 to 733 attached to the shaft of the tenon removing shaft motor 711 can be set to an arbitrary tenon machining length by controlling the positional relationship by the servo motor 835 described above. Then, the tenon removing shaft motor 711 is rotated, and the tenon is cut at the end portion of the workpiece by the movement control by the servo motors 846, 856, and 866 for movement.

  Here, the tenon length change control by the tenon length changing servo motor 835 will be described. This control is realized by the control device executing a control process as shown in FIG. In the tenon length change control, the length of the lower tenon is specified from the input machining data (S110). Also, the length of the upper tenon is specified (S120). Then, the servo motor 835 is driven and controlled according to the length of the lower tenon specified in S110, and the lower tenon tip chamfering cutter 722 is moved to a position corresponding to the lower tenon length (S130). Then, it is determined whether or not the lower tenon has been processed (S140). If it is determined that the lower tenon has been processed (S140: YES), it is determined whether or not the tenon length change corresponding to the upper tenon length specified in S120 is necessary (S150). When it is determined that the tenon length change according to the upper tenon length is necessary (S150: YES), the servo motor 835 is driven and controlled according to the upper tenon length specified in S120, and the upper tenon tip The chamfering cutter 732 is moved to a position corresponding to the upper tenon length (S160).

  Next, characteristics regarding the positioning of the workpiece during the tenoning will be described. For positioning, a stopper head 873 is attached to the upper end portion of a guide shaft 872 for raising and lowering the stopper which is guided by the base 871 on the left and right moving base 851 and operates in the vertical direction. The stopper head 873 moves up and down together with the stopper lifting guide shaft 872 by the air cylinder 874. The stopper head 873 is provided with a workpiece end surface detection sensor 875 that detects when the end of the workpiece W comes into contact.

  Next, the operation of the stopper will be described. The stopper head 873 is raised during the upper tenon processing of the workpiece to be processed first (hereinafter referred to as “first-inserted material”). A processing material to be processed next to the first insertion material (hereinafter referred to as “rear insertion material”) is fed by the pinch rollers 321 to 325, and the front end portion comes into contact with the stopper head 873 and stops (W ( (Refer to the stop state of the last insert).) At this time, the workpiece end surface detection sensor 875 of the stopper head 873 detects the end surface, and the workpiece W is fixed by the fourth vise 344 and the first upper clamp 351. Then, the stopper head 873 descends. Then, when the top tenon processing of the first insert material is finished, the bottom tenon processing of the post insert material is started. The first insert is positioned for upper tenon processing by the positioning unit 920. In this way, by providing the stopper head 873 that protrudes and protrudes at a predetermined distance from the tip of the lower tenon main spindle 801 of the tenon processing unit 700, the upper tenon of the first insert is being processed. The post-insert material can be positioned at the lower tenon processing position.

  The operation of the stopper is performed by the control device executing the control process shown in FIG. The control device determines whether there is a next workpiece from the machining data at the timing of executing the upper tenon machining (S210). If there is a next workpiece (S210: YES), a command signal for causing the rod to move forward to the air cylinder 874 for raising and lowering the stopper is output (S220). Thereafter, it is determined whether or not a later-inserted material is detected by the workpiece end surface detection sensor 875 (S230). When the post-insert material is detected (S230: YES), a command signal for the clamp operation is output to the fourth vise 344 and the first upper clamp 351 (S240). Then, after the clamp by the fourth vise 344 and the first upper clamp 351 is completed (S250), a command signal for causing the air cylinder 874 to perform the rod retraction operation is output (S260). Whether or not the clamping operation by the fourth vise 344 and the first upper clamp 351 has ended is determined by an elapsed time since the command of the clamping operation or an input of an operation end signal from the fourth vise 344 or the like. can do.

  Next, the role of each blade included in the tenon processing unit 700 will be described.

  The lower mortise cutting cutter 721 has a role of cutting the lower mortise from the tip of the workpiece. At the time of tenon cutting by the lower tenon cutting cutter 721, the lower tenon tip chamfering cutter 722 has a role of chamfering the tip of the lower tenon. The end face finishing cutter 723 does not substantially work when the workpiece is cut with the cross cut saw 500. However, when the workpiece is not cut off at the upstream cross-cut saw 500, the end surface finishing cutter 723 acts to finish the lower tenon tip surface. Cutting the tip by the upstream cross-cut saw unit 500 is performed when the state of the tip of the material is poor and it is desired to cut and discard a certain length in advance. On the other hand, when the state of the front end portion of the material is good and the end surface finishing cutter 723 can cleanly process, the end cutting by the cross cut saw unit 500 may not be performed. In this way, since the end cutting process can be omitted and the end face finishing can be performed simultaneously with the mortise cutting, the processing time can be shortened and the processing efficiency can be increased. For this reason, the processing machine 1 includes the end surface finishing cutter 723.

  The upper tenon cutting cutter 731 has a role of cutting the upper tenon from the rear end of the workpiece. At the time of tenon cutting by the upper tenon cutting cutter 731, the upper tenon tip chamfering cutter 732 chamfers the tip of the upper tenon. At this time, the holding and peripheral edge cutter 733 does not perform the cutting operation. The holding / rotating edge cutter 733 is not used at the time of cutting the tenon, but is used at the time of holding, surrounding edge, window lintel notch processing, or the like. In the case of the present processing machine 1, the upper tenon is not provided with an end surface finishing cutter on the upper tenon side, and the upper tenon is the rear end of the workpiece in the loading direction. Therefore, in order to determine the overall length of the column, cutting by the upstream crosscut saw unit 500 is performed. It is essential.

  In the present processing machine 1, as described above, the positional relationship between the lower tenon cutting cutter 721, the lower tenon tip chamfering cutter 722, and the end surface finishing cutter 723 can be arbitrarily adjusted by the servo motor 835. Therefore, the length of the lower tenon can be arbitrarily set. Can be changed. Similarly, the length of the upper tenon can be made arbitrary by adjusting the positional relationship between the upper tenon cutting cutter 731 and the upper tenon tip chamfering cutter 732 by the servo motor 835. Here, when the lower tenon tip chamfering cutter 722 is moved to the spindle motor side by the servo motor 835 in order to lengthen the lower tenon, the opposite upper tenon end surface finishing cutter 732 moves away from the motor. This is because the processing machine 1 has one mortise length adjusting servo motor. However, in this processing machine 1, since the lower tenon and the upper tenon are not processed at the same time, the lower tenon and the upper tenon can be of any length with one servo motor. On the contrary, by using one servo motor, the tenon length changing mechanism can be accommodated in the main shaft motor portion of the tenon processing unit 700.

  Next, a detailed configuration of the takeout conveyor unit 900 will be described.

  As shown in FIGS. 10 to 13, as described above, the takeout conveyor unit 900 includes the takeout conveyor 910, the work material transfer positioning unit 920, the printing device 930, the work material extrusion device 940, and the processed material delivery. A device 950 and a wheel conveyor 980 are provided.

  The processed material delivery device 950 includes a long material placement portion 960 and a short material placement portion 970. The elongate material placement portion 960 is guided by the elevating guide rails 961 attached to the front surfaces of the elevating guide supporting members 911 at three locations extending below the take-out roller conveyor 910, and the entire elevating air is guided by the elevating guide rails 961. A lifting body 963 that is lifted and lowered by a cylinder 952, a longitudinal motion guide rail 964 attached to the upper surface of each lifting body 963, a longitudinal motion beam 965 attached to the longitudinal motion guide rail 964 so as to be movable back and forth, A longitudinal cylinder 951 for moving the longitudinal motion beam 965 back and forth, a stay 967 attached to the front surface of the longitudinal motion beam 965, and a long material delivery bar 968 attached to the stay 967 are provided. The longitudinal movement beam 965 has substantially the same length as the take-out roller conveyor 910. The main body of the forward / backward movement air cylinder 951 is fixed to the take-out roller conveyor 910. Note that the long material delivery bar 968 does not exist in the short material placement portion 970.

  The short material mounting portion 970 includes a short material support bar 971 with a short length attached on the longitudinal motion beam 965, an elevating guide body 972 attached to the longitudinal motion beam 965, and the elevating guide body 972. Elevating guide rail 973 attached to the front surface, elevating body 974 guided by elevating guide rail 973, stay 975 attached to elevating body 974, short material delivery bar 976 attached to stay 975, elevating body And an air cylinder 953 for raising and lowering the short material placing portion for raising and lowering 974.

  The upper wheel conveyor 981 that delivers a long processed material from the long material transfer device 960 is installed at a position corresponding to the entire length of the processed material from long to short. As described above, the upper wheel conveyor 981 is inclined lower toward the front, and the upper surface of the roller at the tip of the workpiece transfer portion is slightly lower than the upper surface of the take-out roller conveyor 910. This height is also slightly lower than the top surfaces of the delivery bars 968, 976 when raised. The lower wheel conveyor 982 corresponds to a short processed material, and is installed in a range corresponding to the length of the short material. Moreover, the lower wheel conveyor 982 is installed so that it may enter under the upper wheel conveyor 981, and has the inclination which a near side becomes low as mentioned above.

  Next, the operation of the long material delivery bar 968, the short material delivery bar 971, and the short material delivery bar 976 will be described.

  At the time of extruding the workpiece, printing, and starting delivery, the entire lifting air cylinder 952 is in the rod protruding state, and the delivery bars 968, 971, and 976 are all in the raised position. The heights of the raised positions of the delivery bars 968, 971, and 976 coincide with the roller upper surface of the take-out roller conveyor 910. At this time, the forward / backward movement air cylinder 951 is in the rod retracted state.

  By the workpiece pushing operation by the workpiece pushing device 940, the workpiece slides and moves on the upper surface of the take-out roller conveyor 910 and the upper surfaces of the delivery bars 968, 971, and 976. As shown in FIG. It is placed on the scale material delivery bar 968 and the short material delivery bar 976 and is moved to the front side of the take-out roller conveyor 910. The short wood Ws is placed only on the short material delivery bar 976 and is moved to the front side of the take-out roller conveyor 910.

  The delivery bars 968, 971, and 976 are raised and lowered as a whole delivery unit by the operation of the overall lifting air cylinder 952. At the time of ascent, as described above, it is at the same height as the take-out roller conveyor 910 and is higher than the upper wheel conveyor 981. On the other hand, the lowering height is slightly lower than the uppermost roller upper surface of the upper wheel conveyor 981.

  The delivery bars 968, 971, and 976 are moved forward and backward as a whole by the operation of the forward / backward movement air cylinder 951. At the time of forward movement, the positional relationship is such that the leading ends of the delivery bars 968 and 976 enter the area covered by the upper wheel conveyor 981 until they intersect with the width of the workpiece. Further, at the time of retreat, the transfer bars 968 and 976 have a positional relationship in which the leading ends of the delivery bars 968 and 976 intersect each other by the width of the workpiece in the region covered by the lower wheel conveyor 982.

  The short material delivery bar 976 performs an elevating operation independent of the long material delivery bar 968 by the forward / backward movement of the air cylinder 953 for raising and lowering the short material placing portion. The height when the short material delivery bar 976 is lowered by the short material placing portion lifting air cylinder 953 is slightly lower than the upper surface of the roller at the tip portion (work material delivery portion) of the lower wheel conveyor 982. This lowering position is achieved by the total of the lowering due to the rod retracting operation of the entire lifting air cylinder 952 and the lowering due to the rod retracting operation of the short material placing portion lifting air cylinder 953. Since this processing machine 1 is configured as described above, the effect that the stroke of the elevating air cylinder 953 for elevating the short material mounting portion can be shortened by the stroke of the entire elevating air cylinder 952 is exhibited.

  Next, the discharging operation corresponding to the length of the workpiece will be described.

[Discharging operation when the workpiece is long]
The processed material W1 is placed on the long material delivery bar 968 and the short material delivery bar 976 (state of W1 in FIG. 11 and state Wa in FIGS. 12 and 13). In this state, by causing the forward / backward movement air cylinder 951 to advance the rod, the workpiece Wl is sent to the upper end of the upper wheel conveyor 981. Subsequently, by causing the entire elevating air cylinder 952 to move backward with the rod, the delivery bars 968 and 976 are lowered to a position slightly lower than the tip end height of the upper wheel conveyor 981. As a result, the processed material Wl is in a state of being hung on the upper end of the upper wheel conveyor 981 (see Wb in FIGS. 12 and 13). The delivery bars 968, 971, and 976 are further lowered. As a result, the work material Wl is rolled and discharged on the upper wheel conveyor 981 by the inclination of the conveyor. When the workpiece is discharged in this manner, the forward / backward movement air cylinder 951 moves backward, the entire lifting air cylinder 952 moves upward, and the delivery bars 968, 971, and 976 return to their original states.

[Discharging operation when the workpiece is short]
The processed material Ws is placed on the short material delivery bar 976. In this state, the workpiece Ws is placed on the upper end of the lower wheel conveyor 982 by the lowering operation of the entire elevating air cylinder 952 and the short material delivery unit elevating air cylinder 953 (state of Wc in FIG. 12). The short material delivery bar 976 is further lowered. Then, the workpiece Ws rolls forward on the lower wheel conveyor 982 due to its inclination. When the work material Ws is discharged in this way, the entire lifting / lowering air cylinder 952 and the short material transfer portion lifting / lowering air cylinder 953 move upward, and the short material transfer bar 976 returns to its original state.

  The above-described discharging operation is executed by the control device performing the following control process based on the machining data. As shown in FIG. 17, the length L of the processed material is acquired from the processing data (S310), and it is determined whether or not this length is equal to or shorter than the predetermined short material length L1 (S320). When ≦ L1, a control command is output to the entire lifting air cylinder 952 and the short material transfer portion lifting air cylinder 953 so as to execute the discharging operation when the workpiece is short (S330). When L> L1, a control command is output to the forward / backward movement air cylinder 951 and the entire lifting / lowering air cylinder 952 so as to execute the discharging operation when the workpiece is long (S340). .

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the scope of the invention.

  For example, in the tenon length change control, a switch or the like for designating the tenon length is provided on the control panel, and when the operator performs a switch operation, the control process similar to that described in FIG. 15 is executed. The length may be changed. Further, the embodiment is configured so that both the lower tenon and the upper tenon can be processed without inverting the wood. However, the tenon is provided with a tenon cutting cutter and a tenon chamfering cutter only at one end of the main shaft. The chamfer cutter is fitted to the main shaft by key connection or spline connection, and the axial position of this tenon chamfer cutter can be changed to any position with a servo motor. The present invention can also be implemented as a processing machine that processes the upper tenon.
