Description

  The present invention relates to a processing machine suitable for processing a workpiece such as a feather material, and in particular, a state in which a workpiece such as a feather material carried in is processed at a lower speed than a stop or a conveying speed in the processing step. In the case where the succeeding workpiece can be conveyed to the next process at a normal conveying speed, the height of the conveying path of the succeeding workpiece and the height of the conveying path of the workpiece being processed are relatively changed. The present invention relates to a processing machine for wood and the like and a method thereof that secures a conveyance path for a subsequent workpiece and enables the subsequent workpiece to be conveyed to the next step.

  In wooden houses, structural materials such as pillars and horizontal members used between them require man-hours for cutting and assembling parts. Has become widespread. Further, since the processing shape of each horizontal member is usually different for each piece, a code such as a number indicating an assembly position is given, and the printing process also requires a certain time.

  On the other hand, due to the increasing demand for further cost reduction of wooden houses, the necessity for factory production of relatively easy-to-process feather pattern materials that have been processed and installed in the construction site is increasing. . Such a feather material or the like is required in large quantities, and it is desired to improve the transportation speed and processing speed of the feather material for the processing.

  In a processing machine suitable mainly for processing a feather pattern material which is an auxiliary member of a wooden house, the wood for the feather pattern material to be processed, that is, the workpiece, in advance, uses such as the rafter and bracing of the workpiece, the length, The shape of the front and rear ends, and therefore the type and length of processing, the roof slope angle, etc. are accumulated as CAD data so that the apparatus in each process is controlled based on the data and the conveyance of the workpiece is controlled. It has become. Further, the code printing of numbers indicating the assembly position of the processed wood and the like and the marking for marking the reference line for attaching the rafters are similarly controlled based on the CAD data.

  That is, usually, after the workpiece is put into the feeding area, it is usually transported one by one in the longitudinal direction of the workpiece based on the CAD data, temporarily fixed in the machining process, and the circular saw or the like. The shape and length of the tip can be adjusted by cutting. Further, the assembly parts are formed by the subsequent steps, that is, as necessary, by predetermined drilling or cutting. Furthermore, in the marking process and the printing process, markings specified by computer control based on the data are applied to the surface positions of the necessary parts of the workpiece, and codes such as assembly numbers are similarly printed, and then the discharging device After that, it is configured to be automatically discharged.

  The wood that has been subjected to the predetermined processing in this manner and has been marked or printed with a code is transported to the construction site and assembled as a house according to the marking or the code.

  However, in such a conventional processing machine, the cutting processing device, the cutting processing device, and the like are arranged on the same conveyance line of the workpiece and can be processed continuously, because of its configuration. While processing a single workpiece, the workpiece is in the transfer path and interferes with the transfer path even though the front and rear processing devices are free and can be processed. For this reason, it has not been possible to start positioning and conveyance for performing cutting processing and the like of subsequent workpieces. Even if this processing process is the above-described printing process or even the discharging process, there is a possibility that the same trouble may occur.

  In a processing machine of this kind of material that requires a relatively large quantity such as a feather pattern material, more efficient processing is required.

  Therefore, the following workpiece can be conveyed to the next process at the normal conveyance speed in the state where the wood such as the feather material, that is, the workpiece, which is carried in, is processed at the processing step at a speed lower than the stop or conveyance speed. In such a case, a transport path for the subsequent workpiece is secured so that the subsequent workpiece can be transported to the next process.

  Therefore, in the invention according to claim 1, in the state that the work such as the feather material that has been carried in is processed at a speed lower than the stop or the conveyance speed in the processing process, the subsequent work is normally used in the next process. If it can be transported at the transport speed, the height of the transport path of the subsequent workpiece and the height of the transport path of the workpiece being processed are relatively changed to secure the transport path of the subsequent workpiece, and the subsequent It is a processing machine for wood and the like that can transport the workpiece to the next process.

  The invention according to claim 2 is a conveying device that conveys a workpiece such as a carried feather material, a cutting device that cuts the workpiece in a conveying path of the workpiece conveyed by the conveying device, and the cutting device. A moving device for moving the conveyance path of the workpiece, which has been cut by the above, to a position that does not interfere with the conveyance path and preparing for the conveyance of the subsequent workpiece, a printing device that prints on the workpiece at the movement position, and a post-printing A processing machine for wood or the like having a discharge device for discharging a workpiece.

  The invention according to claim 3 is “a processing machine for wood and the like according to claim 2, wherein the moving device has a receiving base that receives a workpiece conveyed after being processed in the conveying path and moves downward. .

  The invention according to claim 4 is a state in which a workpiece such as a feather material that has been carried in is processed at a lower speed than a stop or a conveyance speed in the processing step, and a subsequent workpiece is transferred to a normal conveyance speed in the next step. If the transfer path of the subsequent workpiece is relatively changed, the height of the transfer path of the workpiece being processed is relatively changed, and the transfer path of the subsequent workpiece is secured to the next process. This is a method for processing wood or the like that can be conveyed to the outside.

  In the present invention, a workpiece such as a feather material, that is, a workpiece is processed at a lower speed than a stop or a conveyance speed in the machining process, and a subsequent workpiece is transferred to a normal conveyance speed in the next process. In the case where it is possible to transport the workpiece, it is possible to secure a conveyance path for the subsequent workpiece, so that the conveyance of the subsequent workpiece can be started and the machining efficiency is improved.

  In other words, interference with the subsequent workpiece conveyance can be avoided and the processing cycle time can be shortened. Therefore, it is effective even when the end material of the normal rear end part falls, but the long end without the next processing is effective. When the material is discharged, or when the workpiece to be marked after the trailing edge is cut with a rafter, the tip of the subsequent workpiece is not processed, or the processing is completed while the preceding workpiece is being transferred Therefore, the operation of the work puller continues without interruption, which is particularly effective.

(Automatic charging device 10)
The workpiece W automatic loading device 10 is positioned on the workpiece loading side (right side in the drawing) of the conveyance path T, and a plurality of chain conveyors 12 correspond to the length of the workpiece W in a direction orthogonal to the conveyance path T. The roller conveyor 14 forming a conveyor table is arranged at a position where the conveyance center coincides with the conveyance path T. Accordingly, the workpiece W put on the chain conveyor 12 is moved to the transport path T side by the feeding operation of the chain conveyor 12.

  In addition, the loading work W is thrown onto the chain conveyor with its tip abutted against a side guide 13 provided on the side edge of the processing device of the chain conveyor 12, that is, the cutting device.

  A plurality of chain conveyors 12 are provided in parallel with the roller conveyor 14 so as to be moved up and down with respect to the transport surface of the chain conveyor 12 near the transport path T, located on the front end side in the transport direction of each chain conveyor 12. The stopper 16 is provided, and the workpiece W sent by the chain conveyor 12 is conveyed until it hits the stopper 16 positioned above this.

  An arrival sensor 17 is arranged in the vicinity of the most downstream side of the stopper 16 in the transport path T to detect the arrival of the workpiece W. The arrival sensor 17 confirms that the workpiece W has been conveyed to the stopper 16. At this time, the chain conveyor 12 is driven for a predetermined time from the detection by the sensor 17 and then stopped, so that the workpiece W hits the plurality of stoppers 16 and the workpiece W is positioned so as to be parallel to the roller conveyor 14. The

  A chuck 18 having a plurality of retracting chucks 18a is disposed on the opposite side of the transport path T from the chain conveyor 12. Although the chuck 18 is not shown in its entirety, a plurality of drawing chucks 18a are installed on a bar that is mounted on a rail and can be moved by a cylinder, and the drawing chucks 18a freely move in the vertical direction. The lower gripper is fixed to the slider, and the upper gripper is moved up and down by a cylinder in a rail structure provided on the slider. Therefore, based on a control signal to be described later, the workpieces W positioned by the stopper 16 are gripped from above and below, and each one is drawn to the roller conveyor 14 side, and hence into the transport path T, and then released. It is configured.

  Further, a front end cutting feed roller 19 and a work confirmation sensor 19A are arranged in that order on the front side of the roller conveyor 14 in the conveying direction. As can be seen from FIG. 2, the feed roller 19 is positioned so as to be movable up and down above the transport path T. The feed roller 19 is lowered during transport driving, and the workpiece W is driven along the longitudinal direction by driving the feed roller 19. Then, it is conveyed to the cutting device 20 side.

  The feed roller 19 is driven by a servo motor (not shown), and can position the workpiece W in the direction of the conveyance path T. The feed roller 19 descends from above the workpiece W and is moved at a predetermined pressure. After contacting with W, it is rotationally driven to convey the tip of the workpiece W to a predetermined position in the cutting device 20.

  That is, after the tip of the fed workpiece W is detected by the workpiece confirmation sensor 19A, measurement is started, and the feeding roller 19 moves the workpiece W into the cutting device 20 to the position given by the machining data. It is configured to carry and position.

(Cutting device 20)
Next, as clearly shown in FIG. 2, in the cutting device 20, the circular saw 22 is arranged so as to be movable up and down so as to cross the conveyance path T of the workpiece W, and the angle thereof is set in a vertical plane and a horizontal plane. It can be changed within. That is, the horizontal and vertical angles of θ1θ2 of the circular saw 22 controlled in five axes are positioned, and the circular saw 22 operates in the three-dimensional directions of XYZ to cut the workpiece W tip into a predetermined shape. The circular saw 22 is configured not to interfere with the movement of the workpiece W by retracting downward from the conveyance path T when the cutting operation is not performed.

  In front and rear positions of the cutting device 20 in the conveyance path T direction, inlet-side and outlet-side cutting clamps 24 and 26 are arranged, respectively, at the time of leading edge cutting, at the time of trailing edge cutting described later, and as necessary. At the time of cutting the intermediate portion, the workpiece W is selectively clamped before and after the respective control signals. The cutting clamps 24 and 26 are respectively composed of a lateral clamp 24A and an upper clamp 24B, a lateral clamp 26A and an upper clamp 26B, and the operation of each clamp causes the workpiece W to be centripetally laterally and further upward. It can be pressed firmly and clamped for proper cutting. That is, as described above, the horizontal and vertical angles of the 5-axis controlled circular saw 22 are positioned by the processing data given simultaneously, and the circular saw 22 operates in a three-dimensional direction so that the tip of the workpiece W has a predetermined shape. To be processed.

  That is, when the workpiece W is a rafter, the tip and rear ends are cut at a predetermined angle based on the CAD data. Configured to be.

  A positioning puller 50 is disposed at the final end of the transport path T so as to face the traveling direction. The positioning puller 50 has a puller chuck 52 for gripping the front end of the work W at the front end thereof, and the transport path. A guide 54 along T allows the workpiece W to be selectively positioned and fixed at the moving position in accordance with a control signal based on CAD data. Further, the pull chuck 52 grips the front end of the workpiece W based on the control signal and moves along the transport path T, and can be fixed.

Therefore, as described above, the workpiece W that has been automatically loaded is processed on the same pass line, that is, the conveyance path T, from the front end cutting processing to the rear end cutting processing. After the front end machining of the workpiece W is finished, the circular saw 22 moves to the retracted position, and then the positioning puller 50 is positioned and fed to the workpiece tip gripping position in the machining apparatus 20 by the given machining data.
Then, after gripping the tip of the workpiece W, the cutting clamp 24 is opened and moved to the rear end cutting position, and the rear end of the workpiece W which has completed the rear end cutting processing thereafter is the workpiece described later. It is conveyed while being gripped by the chuck 52 of the positioning puller 50 until it passes the rear end guide, and the chuck 52 is opened at that position, and the workpiece W is placed on a print table described later.

The movement / stop / gripping / release operation of the positioning puller 50 and the chuck 52 is performed based on position data calculated from numerical values given by all CAD data relating to the workpiece W to be transported, as described above. Thus, the puller 50 and the cutting device 20 are operated, and a cylinder (not shown) with an operation confirmation sensor for driving the puller chuck 52 according to the given conditions is provided.
(Printer 30)
As shown in an enlarged view in FIG. 3, a printing device 30 is arranged at the rear stage along the conveying path T of the cutting device 20. The marking device 32 (FIG. 2) is at the front stage, and the print head is at the rear side. 34 is provided.

  The marking device 32 is not shown in detail, but, as is well known, an upper edge that normally forms an acute angle in order to apply a linear marking (burn) to the surface of the wood, ie, the workpiece W, by heating. A metal marking bar equipped with a heater inside, a cylinder for pressing the bar against the workpiece W, that is, wood, and an angle positioning table for turning the bar to an angle according to the roof slope A marking device provided. This marking is a reference line used when attaching a rafter which is a roof member.

  Further, the printing device 30 is provided with a cradle for receiving the workpiece W conveyed from the cutting device 20 after the cutting process, that is, a printing table 36 along the conveyance path T.

  As shown in FIGS. 4 and 5, the print table 36 is moved up and down in the vertical direction in parallel with the transport path T together with a discharge table, which will be described later. It is supported by an elevating device 36A such as a cylinder as a moving device so that it can be changed. And the workpiece | work W which has passed the processing apparatus 20 is mounted in the raise position.

  As shown in FIG. 3, the printing apparatus 30 is configured such that printing is performed on the work W by the print head 34 based on the print data at a position where the print table 36 on which the work W is placed is lowered. Has been. That is, the print pressing pusher 37 and the print reference guide 38 opposed to the print pusher 37 are arranged facing the transport path Td corresponding to the lowest position of the print table 36, and the print feed bar 39 is fed by the print feed motor M. The assembly number and the like are printed by the print head 34 while feeding the workpiece W along the reference guide 38.

  Further, as shown in FIG. 5, a plate-shaped workpiece rear end guide 56 is provided substantially vertically with a tilted guide portion on the conveyance path T, as shown in FIG. The puller 50 opens the workpiece W and descends after placing the workpiece W on the print table 36, but is configured to guide the rear end of the workpiece W so as not to come off the print table 36. Although this rear end guide 56 is not an essential configuration, it can guide the workpiece W to a predetermined position such as a table that can be stably moved even when the workpiece W made of wood is slightly deformed. .

  Then, based on the control data, when the positioning puller 50 releases the chuck 52 at a timing when the rear end of the work W conveyed by the positioning puller 50 exceeds the work rear end guide 56, the work W is The rear end is guided by the guide 56, and the work W having the front end and the rear end cut and processed is placed on the print table 36 and a discharge table described later.

  On the other hand, if it is determined that the preceding work W does not interfere with the transport of the subsequent work W ′ by changing the transport path T to the transport path Td based on the already input data, It is configured to start the conveyance of W ′.

  That is, in the lowered position of the print table 36 shown in FIG. 5, the transport path Td on the table 36 moves the subsequent work W ′ transported along the transport path T in the raised position. Even if the succeeding workpiece W ′ starts to be conveyed by the roller conveyor 14 in this state, that is, in a state where the workpiece W is stopped or conveyed at a lower speed than the conveying speed, the height is changed to a position where it does not interfere. The workpiece W ′ is transported on the original transport path T, proceeds without any interference with the preceding work W on the lowered transport path Td, and can be subjected to the cutting process by the cutting device 20. Then, it is placed on the printing table 36 that has been lifted and restored in the subsequent steps and a discharge table described later. This state of being conveyed at a low speed corresponds to the same state for the discharge chain conveyor related to the discharge table described later.

  When the rear end of the work W has advanced to a position past the work rear end guide 56, the subsequent work W ′ is drawn into the roller conveyor 14 as described above.

  The leading edge, the trailing edge, and the presence / absence of intermediate machining processing or the processing content according to the processing data of the workpiece W is generated from a control device (not shown) as CAD data. Since the processing contents of the workpiece W and the subsequent workpiece W ′ are known in advance, it is possible to arrange the setting of the conveyance path Td that does not interfere with the conveyance path T according to the conveyance order.

(Automatic discharge device 40)
As shown in FIG. 3, in the automatic discharge device 40, as described above, the discharge table 42 is disposed along the transport path T and the control signal is output in the same manner as the print table 36. Based on this, the printing table 36 is supported at the same height as the printing table 36 so as to be movable up and down so that the raising and lowering position can be changed in the vertical direction by the raising and lowering device 40A such as a cylinder.

  As shown in FIG. 5, the conveyance path of the workpiece W formed by the discharge table 42 being lowered is a conveyance path Td that coincides with that of the print table 36, and a plurality of discharge chain conveyors 44 perpendicular to the conveyance path Td. They are arranged in parallel and facing the transport path Td. A discharge pusher 46 (see FIG. 3) is disposed on the side of the lowered table 36. The discharge pusher 46 is driven by a control signal, presses the workpiece W at the position where the processing process is finished and is placed on the print table 36 and the discharge table 42 and descends from the side surface, and the discharge chain is discharged from the transport path Td. The paper is discharged to the conveyor 44 side. The discharged work W is automatically discharged forward by the discharge chain conveyor 44 in parallel with the paper surface in FIG.

(Description of operation)
A series of operations of the embodiment of the present invention configured as described above will be described below.

  First, the feather material to be processed, that is, the workpieces W, is loaded into the automatic loading apparatus 10, one by one. In this case, for example, if the workpiece W is a rafter, it is efficient to process it intensively. Therefore, a standard object is introduced and divided into a predetermined length as necessary. In many cases, the same cutting process is performed. That is, when the workpiece W is perpendicular to the chain conveyor 12 and the tip of the workpiece W is abutted against the side guide 13 and placed on the chain conveyor, the workpiece W is sequentially moved in the direction of the conveyance path T by the chain conveyor 12. It is moved one by one in the direction of the roller conveyor 14 and conveyed to the stopper 16.

  The workpiece W is detected by the arrival sensor 17, the plurality of drawing chucks 18 a are operated, are gripped, and are drawn onto the conveyor table, that is, the roller conveyor 14. The workpieces W are conveyed one by one by the roller conveyor 14 in the left direction in the drawing, that is, in the direction of the cutting device 20.

  First, the tip cutting feed roller 19 descends from above by a control signal based on CAD data, contacts the workpiece W, and rotates to convey the tip of the workpiece W to a predetermined position in the cutting device 20. . At this time, after the leading end of the workpiece W is detected by the workpiece confirmation sensor 19A, after the rotation corresponding to the leading end cutting length given by the data is performed, the feeding of the feed roller 19 is stopped and the inside of the cutting device 20 is stopped. The tip of the workpiece W is positioned and conveyed at a predetermined position.

  In a state where the workpiece W is fixed by the clamp 24, the circular saw 22 operates based on the machining data, and the predetermined machining for the tip ends. After the machining is completed, the circular saw 22 moves to the retracted position, and then the positioning puller 50 is positioned and fed to the workpiece tip grasping position in the machining apparatus 20 by the given machining data, and the chuck 52 grips the tip side surface of the workpiece W. To do. Upon completion of this gripping, the clamp 24 is released, and the positioning puller 50 positions and feeds the workpiece W to the rear end cutting position based on the given machining data. Further, the gripped work W is transported to the next processing position. At this time, based on the control data, the subsequent workpiece W ′ is drawn into the roller conveyor 14 at the timing when the rear end of the workpiece W has advanced to a position past the workpiece check sensor 19A. .

  On the other hand, upon completion of positioning of the positioning puller 50, the lateral clamp 26A and the upper clamp 26B on the outlet side are actuated on the workpiece W, and the circular saw 22 is actuated in the same manner as the tip machining, and after the given shape. Edge processing is performed. At this time, the chuck 52 of the puller 50 continues to be gripped. In addition, depending on the relationship between the material length of the workpiece W and the processing length, the remaining member at the rear end may drop downward as an end material on the spot, may not drop, or may take more products from the remaining material. However, the basic operation is the same for both.

  When the processing of the rear end is completed and the clamp 26 is released, the workpiece W is conveyed to the discharge position of the print table 36 that can be moved up and down by the positioning puller 50 given discharge position data. In this state, the cutting device 20 and the printing device 30 are installed close to each other along the conveyance path T.

  Here, as described above, the subsequent workpiece W ′ is simultaneously fed into the cutting device 20 and the tip processing is performed by the same operation as described above.

  As described above, the workpiece W that has been automatically loaded has the same conveyance path T, that is, a pass line, based on the control data or the processing data until the front end is cut, the intermediate portion is processed as necessary, and the rear end is cut. Processed above. Next, the workpiece W whose cutting of the rear end is completed is conveyed while its front end is gripped by the puller chuck 52, and at the timing when the rear end exceeds the workpiece rear end guide 56, the positioning puller 50 is stopped and the puller chuck is stopped. 52 is opened.

  On the other hand, the workpiece W, which has been positioned for discharge, is lowered by the print table 36 together with the discharge table, and is positioned on the transport path Td from the processing apparatus reference height to the print height.

  Simultaneously with the lowering of the print table 36 following the opening of the puller chuck 52, the positioning puller 50 is immediately advanced to the standby position close to the cutting device 20, that is, the workpiece W leading gripping position, and sent to the subsequent workpiece W ′. If the front end machining is completed, it is simultaneously fed into the processing apparatus 20 to grip the front end of the workpiece W ′, retracts in the same manner as described above, and is positioned and fed to the rear end cutting position.

  That is, when the preceding workpiece W is processed at a lower speed than the stop or the conveyance speed in the machining process and the subsequent workpiece W ′ can move to the next process at the normal conveyance speed, Since the height of the conveyance path is different and does not interfere, the subsequent workpiece W ′ can be conveyed to the next process.

  Further, the work W on the printing table 36 lowered to the lowest position is pressed against the printing reference guide 38 by the printing pressing pusher 37 and the rear end thereof is pressed by the printing feed bar 39 after the pusher is restored. While being fed, printing is carried out to the discharge position at the same time as printing on the side surface.

  At this time, the feed speed is preferably about 10 m / min, and the feed length is preferably about 1 m. This printed content includes part names (rafters and braces) / part number / attachment position information / product length, etc. necessary for inspection, packing and attachment of members. The pulling speed of the puller 50 is preferably 100 m / min and the printing speed is preferably 10 m / min.

  When this printing is completed, it is detected by a signal, the work discharge pusher 46 is activated, and the work W is discharged to the discharge chain conveyor 44 side. The workpiece W after printing is automatically discharged by the discharge chain conveyor 44.

  When the print table 36 is lowered, the transport path Td on the table 36 is changed to a height that does not interfere with the transport path T of the preceding work W. The conveyance and processing operation of W ′ can be started.

  The printed workpiece W conveyed to the discharge position is pushed out onto the discharge chain conveyor 44 orthogonal to the print table 36 by the discharge pusher 46. When the discharge pusher 46 returns, the print table 36 moves up. Return to the original processing machine reference height.

  At this time, the processing of the leading and trailing ends of the succeeding workpiece W ′ is finished, the leading end is grasped by the positioning puller 50, and can be positioned and conveyed at the processing machine reference height on the print table 36. This is the state when driving.

  In addition, when a device for performing other processing on the intermediate portion of the workpiece W, particularly a marking device for indicating the mounting position of the rafter as described above, is required, a processing machine is provided between the cutting device and the printing device. It can be installed at a reference height, and intermediate processing can be performed between positioning to the rear end portion processing position or positioning of the discharge position after rear end portion processing.

  In the embodiment described above, the height of the transport path is set in the descending and rising order. However, in other embodiments, the height of the transport path is relatively increased in the order of rising and descending. Although it is possible to prevent the conveyance path from interfering, the above-described embodiment is more advantageous because of the simplicity of the structure.

In any case, the height of the conveyance path of the subsequent workpiece and the height of the conveyance path of the workpiece being processed are relatively changed to secure the conveyance path of the subsequent workpiece, and the subsequent workpiece is moved to the next. Further, in the above-described embodiment, the discharge raising / lowering table 40 is lowered, the conveyance path Td is changed to a position that does not interfere with the conveyance path T of the subsequent workpiece W, and the printing apparatus is also lowered. However, the present invention is not limited to this, and when the workpiece W moves relatively and the length of the work W is short, at least one of the printing device and the discharge device is lowered to move the conveyance path. By processing the workpiece by changing the transfer path of the subsequent workpiece to a position where it does not interfere, it is possible to efficiently perform the processing of the workpiece such as the feather material without useless waiting time.
