When there is a process to be executed with the surface facing sideways, the processing order determining means selects [input] → [first processing (first processing apparatus)] → [removal] → [input] → [first Processing and printing (second processing device)] → [return] → [rollover] → [second processing (second processing device)] → [removal] and the processing order is determined, and the rollover angle in the discharge control = [90 degrees (or 270 degrees or -90 degrees)] is set. This is because the reference plane of the wood at the stage of loading into the first processing apparatus and the second processing apparatus is upward, and the reference plane of the wood taken out from the second processing apparatus is sideways.

[Case 3]
Furthermore, there is only pre-cut data for other wood that can be executed with the reference surface facing sideways for the first processing device, and processing and reference that can be executed with the reference surface facing upward for the second processing device. When there is a process to be executed with the surface facing sideways, the process order determination means selects [rollover] → [input] → [second process (first processing apparatus)] → [removal] → [input]. → [Second processing (second processing equipment)] → [Return] → [Rolling over] → [First processing and printing (second processing equipment)] → [Ejection] and then determining the processing order and discharging The rollover angle in the control = [180 degrees] is set. The reference plane of the wood at the stage of input to the first processing apparatus is upward, the reference plane of the wood at the stage of input to the second processing apparatus is lateral, and the reference of the wood taken out from the second processing apparatus This is because the surface is facing upward.

  In addition, when the rollover device is installed in the wood conveyance device on the wood take-out side, the processing order in which [Return] → [Rollover] → [Input] in [Case 1] to [Case 3] is [Eject] → [Tumble] → [Return].

  As described above, according to the present invention, the processing to be executed in each of the plurality of processing devices is performed by performing the rollover by the rollover device installed in the wood conveying device corresponding to each processing device, as required. The processing or the second processing is continuously executed. As a result, the cycle time in the precut process can be shortened. Then, based on the result of the rollover operation by the processing order determining means, the rollover angle when the rollover operation by the rollover device installed on the discharge device is required is set, so that the printing surface of the wood discharged to the discharge device faces upward And there is no hindrance to work such as collection / delivery and packing of processed wood. In addition, according to the wood pre-cut processing equipment of the present invention, various processing can be performed individually by installing a rollover device for each of the processing devices with respect to the wood conveying device on the input side or the extraction side of the wood. It is possible to determine the processing order that can shorten the cycle time even when new hardware is being developed one after another, and contribute to the improvement of the cycle time in the wood pre-cut processing equipment. Can do. In addition, facilities that can be applied to both pillars and horizontal members can be processed with rollovers that are unique to pillars without increasing the machining axis, thereby contributing to shortening the cycle time of the equipment. it can.

  Below, the Example of the wood precut processing equipment 1 to which this invention is applied is described.

[1 Outline of the entire facility]
As shown in FIG. 1, the wood pre-cut processing facility 1 according to the embodiment includes a material loading lateral transfer conveyor 10, a material loading conveyor 20, a side surface processing / full length cutting device 30, a takeout conveyor 40, and a workpiece horizontal transfer conveyor from the upstream side. 50, a workpiece input conveyor 60, an end processing / printing device 70, a discharge conveyor 80, a discharge wheel conveyor 90, and an inclined discharge rail 95.

  The material loading lateral transfer conveyor 10 is composed of four chain slashers 11 to 14. When the material is input, as shown in FIG. 2A, the materials W01 and W02 are placed so as to straddle the central two chains 12 and 13. At this time, when the material is for column material processing, the material is placed on the chain slasher with the start point at the time of creating the plan as the front end and the south surface facing downward. Further, when the material is used for processing the horizontal member, the material is placed on the chain slasher with the starting point at the time of creating the plan as the front end and the upper surface facing downward. In addition, the starting point at the time of creating a plan is the lower end during construction in the case of a pillar material, but in the case of a horizontal member, one of the two ends is arbitrarily designated by the creator of the plan. Further, in this embodiment, information specifying the member such as the owner name and street address is printed on the column material near the rear end of the south surface and the horizontal member on the entire length of the upper surface. In addition, the information on the hardware to be attached is printed in the vicinity of the mounting position of the hardware on the south surface in the case of a pillar material, and in the vicinity of the mounting position of the hardware on the upper surface in the case of a horizontal member. As mentioned above, the lumber for column processing at the time of drafting is placed with the south side facing down, and the lumber for horizontal work is placed with the top side facing down. The surface that is in contact with the roller, that is, the surface that is in contact with the roller is the printing surface. This is because the material composition of wood is not constant, and since there are many types, it is possible to prevent complication of the machine by using a fixed surface without providing a moving mechanism of the printing device by making the printing surface a roller surface. It is.

  The material that has been laterally transferred in the material width direction from the material loading lateral transfer conveyor 10 is transported in the longitudinal direction by the material loading conveyor 20 and is input to the side surface processing / full length cutting device 30, where full length cutting and side surface processing are performed. Applied. Full length cutting is performed in the order in which the processing position has arrived at each unit position after being transported in the loading direction.If the full length cutting position is reached before each unit position, it is further transported in the loading direction after performing full length cutting. The cycle time is shortened by performing all the processing and cutting without returning the wood by processing by the unit. If rollover is required, the surface that does not require rollover is first transported and processed in the loading direction, returned to the material loading conveyor 20 with the surface that requires rollover and the full-length cut remaining, and rolled over and loaded to each unit position. Processing, cutting and discharging in the order of arrival. The positioning of the wood during such side processing, full length cutting, and the like is performed by a transfer positioning device 35 guided by a guide rail 45 installed along the takeout conveyor 40.

  In the material loading conveyor 20, the wood placed on the rollers is 90 degrees, 180 degrees, 270 degrees (or -90 degrees, -180 degrees, -270 degrees) and 90 degrees increments around the axis. A rollover device 200 including rollover units 210A to 210C for rolling over is installed. This rollover device 200 rolls the wood by a predetermined angle before putting it into the side surface processing / full length cutting device 30, so that the surface for processing the side surface can be processed in a direction in which the processing tool can execute the processing operation. It is for making it go.

  In this embodiment, the side processing / processing by the full-length cutting device 30 performs side processing that can be performed without changing the orientation of the reference plane of the wood (the south surface of the column material and the top surface of the horizontal member in the plan view). It is supposed to be executed continuously over the entire length. Then, when there is side surface processing that cannot be performed unless the orientation of the reference plane of the wood is changed, the direction of the reference plane of the wood is changed by the rollover device 200.

  For this reason, for certain wood, processing that does not require changing the orientation of the reference surface at the time of material input (first processing), processing that requires changing the orientation of the reference surface at the time of material input (second processing), Are mixed, the timber placed on the material loading conveyor 20 is loaded as it is into the side surface processing / full length cutting device 30 without being overturned, and the transfer positioning device 35 performs positioning in the longitudinal direction. After carrying out the side surface processing while continuously conveying, after returning the wood from the side surface processing / full-length cutting device 30 to the material loading conveyor 20, the rollover device 200 is operated to change the direction of the reference surface and then the side surface again. The processing / full length cutting device 30 is loaded to perform side surface processing and full length cutting.

  In addition, when a certain piece of wood is only processed (second processing) in which the orientation of the reference surface at the time of material input needs to be changed, the wood horizontally transferred in the material width direction from the material input horizontal transfer conveyor 10 is Then, the rollover is performed by the rollover device 200, the orientation of the reference surface is changed so that the second machining can be performed, and then the side surface machining / full length cutting device 30 is loaded, and the transfer positioning device 35 performs positioning. Side surface processing and full length cutting are performed while continuously conveying in the longitudinal direction while performing.

  In addition, when only a processing (first processing) that does not require changing the orientation of the reference surface at the time of material input for a certain wood, the wood that has been laterally transferred in the material width direction from the material input lateral transfer conveyor 10 is Then, the side processing and full length cutting device 30 is thrown into the side processing and full length cutting device 30 without performing rollover, and the side positioning and full length cutting are executed while continuously transporting in the longitudinal direction while performing positioning by the transfer positioning device 35.

  The processed material that has been processed by the side surface processing / full length cutting device 30 is laterally transferred from the take-out conveyor 40 in the material width direction and sent to the processed material horizontal transfer conveyor 50. At this time, depending on the length of the processed material, as shown in FIG. 6 (A), the central two rows of conveyors 52 in the four rows of horizontal feed conveyors 51 to 54 constituting the processed material horizontal transfer conveyor 50, The processing material take-out position on the take-out conveyor 40 is positioned so that the center of 53 and the centers of the work materials W11 and W12 substantially coincide with each other. Note that the direction of the reference surface of the wood placed on the roller of the takeout conveyor 40 is different from the direction of the reference surface when the material is charged when rollover is performed.

  The processed material laterally transferred in the material width direction by the processed material horizontal transfer conveyor 50 is input to the edge processing / printing device 70 by being conveyed in the longitudinal direction by the processed material input conveyor 60. Also on the workpiece feeding conveyor 60, the direction of the slit groove by the end machining is adjusted to the machining direction of a tool such as a grooving circular saw or the printing surface is faced to the printing device. A rollover device 600 including rollover units 610 </ b> A to 610 </ b> C for rollover at degrees (or −270 degrees), 180 degrees (or −180 degrees), and 270 degrees (or −90 degrees) is installed.

  The edge processing and printing by the edge processing / printing device 70 is also changed in the direction of the reference plane of the wood (the south surface of the column material and the upper surface of the horizontal member in the plan view) as in the processing by the side surface processing / full length cutting device 30. End processing and printing that can be performed without any problem are continuously performed over the entire length of the workpiece. Then, when there is end processing and printing that cannot be performed without changing the orientation of the reference plane of the wood, the rollover device 600 changes the orientation of the reference plane of the wood.

  Here, in side machining and full length cutting, machining that does not require changing the orientation of the reference surface at the time of material input is “first machining”, and machining that requires changing the orientation of the reference surface at the time of material introduction is designated as “first machining”. 2 processing ". However, in edge processing / printing, it is not necessary to change the orientation of the reference surface based on the orientation of the reference surface when the processing by the side surface processing / full length cutting device 30 is finished and taken out to the takeout conveyor 40. Is referred to as “first processing”, and processing that requires changing the orientation of the reference surface is referred to as “second processing”.

  As described above, when the “second processing” exists in the side surface processing / full length cutting, the direction of the reference surface is in a state different from the direction of the reference surface when the material is charged. Therefore, whether the “first processing” or the “second processing” is performed in the edge processing / printing device 70 depends on the presence / absence of the “second processing” by the side surface processing / full-length cutting device 30. It will change. Therefore, it is necessary to change the orientation of the reference surface when the material is put in to determine whether there is “first processing” or “second processing” in the processing by the edge processing / printing device 70. However, it is determined whether or not it is necessary to change the orientation of the reference surface of the workpiece placed on the workpiece feeding conveyor 60. However, since printing is performed on the reference surface when the material is input, it is determined whether or not the reference surface when the material is input matches the reference surface when the workpiece is input.

  In the case where the reference surface at the time of material input is the same as the reference surface at the time of input of the work material, both “first processing” and “second processing” exist in the processing by the edge processing / printing device 70. First, processing and printing are performed by the edge processing / printing device 70 while conveying the processing material in the longitudinal direction while being placed on the processing material input conveyor 60, and then to the processing material input conveyor 60. Then, after the rollover by the rollover device 600 is executed, it is conveyed again to the edge processing / printing device 70 in the longitudinal direction to perform the processing. When only the “second processing” is performed, While the workpiece is placed on the material feeding conveyor 60, printing is performed by the edge processing / printing device 70 while conveying the workpiece in the longitudinal direction, and thereafter, the printing is returned to the workpiece feeding conveyor 60 and is performed by the rollover device 600. After performing a rollover, end again Processing is carried out by transporting to the processing / printing device 70 in the longitudinal direction, and in the case of “first processing only”, feeding and printing are performed to the end processing / printing device 70 without operating the rollover device 600. In the case of no processing, printing is performed by the edge processing / printing device 70 while conveying the processing material in the longitudinal direction while remaining on the processing material feeding conveyor 60. Also, when the reference surface at the time of material input is different from the reference surface at the time of input of the workpiece, and both “first processing” and “second processing” exist in the processing by the edge processing / printing device 70 First, processing by the edge processing / printing device 70 is performed while transporting the processing material in the longitudinal direction while being placed on the processing material input conveyor 60, and then returning to the processing material input conveyor 60. After the rollover by the rollover device 600 is performed, the end processing / printing device 70 is again transported in the longitudinal direction to perform processing and printing. When only the “second processing” is performed, the end processing / printing is performed. Before the feed to the printing device 70, the rollover device 600 rolls over, and the end processing / printing device 70 performs the feed processing and printing. When only the “first machining” is performed, first, the workpiece feeding conveyor Machining while mounted on 60 Is processed in the longitudinal direction by the end portion processing / printing device 70, and then returned to the workpiece input conveyor 60 to perform the rollover by the rollover device 600, and then again to the end portion processing / printing device 70. In the case of no processing, roll over by the rollover device 600 before sending it to the end processing / printing device 70, and feed printing to the end processing / printing device 70. It becomes.

  The processed material that has been subjected to end processing and printing by the end processing / printing device 70 is sent out to the discharge conveyor 80 while being positioned according to the length of the processed material. The processed material of a predetermined length or less is stopped at a position where it can be discharged by the inclined discharge rail 95 and is discharged by operating the inclined discharge rail 95. A processed material having a length equal to or longer than a predetermined length is transported in the longitudinal direction to a position where it can be discharged by the discharge wheel conveyor 90, and extruded in the material width direction by an extrusion device 85. In the present embodiment, the discharge by the inclined discharge rail 95 is performed when the distance is less than 1500 mm, and the discharge by the discharge wheel conveyor 90 is performed when the distance is 1500 mm or more.

  The processed material of 1500 mm or more is discharged to the discharge wheel conveyor 90 after being rolled over by the rollover units 810 </ b> A to 810 </ b> E so that the printing surface faces upward at a position where the processed material is pushed from the discharge conveyor 80 in the material width direction.

[3 Details of the rollover device]
As shown in FIG. 3, the rollover device 200 includes guide rails 213 and 213 installed on the back side so as to extend in the vertical direction along the vertical portions of the frames 211 and 212 of the material loading conveyor 20, and each guide rail 213. Is provided with an elevating body 215 having linear bearings 214 and 214 that are fitted to each other, and an air cylinder 216 that moves the elevating body 215 up and down.

  As shown in FIGS. 3A1 and 3A3, the three rollover units 210A to 210C are attached to the lifting body 215 and configured to move up and down integrally. The rollover units 210 </ b> A to 210 </ b> C are also configured to perform a rollover operation integrally with a rotary shaft 219 that is horizontally supported via a pillow-type bearing unit 218 with respect to the lifting body 215.

  The rotating shaft 219 is rotated by an air cylinder 221 supported by a cylinder bracket 220 attached to the back surface of the elevating body 215. More specifically, a pinion gear 223 that meshes with a rack 222 connected to a rod of the air cylinder 221 is attached to the rotary shaft 219. As shown in FIG. When 222 is moved up and down, the pinion gear 223 rotates and the rotating shaft 219 rotates, and a rollover operation is performed as described later.

  Prior to this rollover operation, as shown in FIGS. 3A2 to 3C2, the rod 216b of the air cylinder 216 is extended, and the elevating body 215 is raised. As a result, the rollover units 210 </ b> A to 210 </ b> C are raised, and the wood W placed on the roller 21 is scooped up by the belt 235.

  As shown in FIGS. 3 (C1) and 3 (C2), the elevating body 215 has a U-shaped recess provided with a U-shaped recess 224a whose center is recessed like a U-shaped groove section from the top to the bottom. Attached plate 224 is attached. The U-shaped plate 224 is provided with one gear 225, four free gear idler pulleys 226, and two sprockets 227. The opening of the U-shaped depression 224a is dimensioned to be able to straddle the roller 21 of the material loading conveyor 20. The U-shaped recess 224 is attached to the U-shaped recess 224 such that the gear 225 is positioned at the lower rear portion of the U-shaped recess 224a and the two sprockets 227 and 227 are positioned at the upper and lower ends of the U-shaped recess 224a. It has been. Further, four idler pulleys 226 are provided, one at the front and rear lower portions of the U-shaped depression 224a, one at the front lower portion just below the front sprocket 227, and one between the rear sprocket 227 and the gear 225. Each is attached. A chain 228 is attached so as to be wound around the gear 225, the idler pulley 226, and the sprocket 227. The gear 225 is fixed to the rotating shaft 219, and rotates when the rotating shaft 219 rotates, and has a mechanism for rotating the sprocket 227 via the idler pulley 226.

  As shown in FIG. 4B, the sprocket 227 is fitted to one end of a shaft 230 that is pivotally supported by a bracket 229 attached to the upper end portion of the U-shaped recessed plate 224. The shaft 230 is attached so as to be rotatable with respect to the bracket 229 via two bearings 231 and 231. A roller 232 is fitted to the other end of the shaft 230. The sprocket 227 and the roller 232 are fixed so that the shaft 230 is sandwiched from the front and rear by bolts 233 and 234, respectively.

  In this way, a belt 235 is wound around one of the rollers 232 attached so as to rotate together with the sprocket 227 so as to be fed out from the other roller. The belt-like belt 235 is attached so as to hang down in a state where it can be wound around by two rollers 232 and 232 at the front and rear of each plate 224 so as to straddle the U-shaped depression 224a, and does not scoop up the wood W Is in a sagging state.

  As shown in FIG. 3 (C2), the rollover units 210A to 210C lift the wood W placed on the roller 21 from below by the belt 235 by raising the elevating body 215 by the air cylinder 216. Let it float from the roller surface. When the wood W is raised, the wood W is lifted in a state where the two apex portions on the lower surface side are in contact with the belt 235, so that the wood W rises straight up regardless of the material width. When the wood W is thus lifted from the roller surface, as shown in FIG. 5, the rack 222 is moved up and down by the air cylinder 221 to rotate the pinion gear 223, thereby rotating the rotating shaft 219. 225 is rotated, and the sprockets 227 and 227 are rotated in the same direction via the chain 228. Accordingly, the belt 235 is wound around the other roller 232 while being fed out from the one roller 232. At this time, the timber W lifted in a state in which both corners of the lower surface are in contact with the belt 235 is rolled over as the belt 235 moves.

  The wood W is lifted by the 90 ° rollover shown in FIGS. 5 (A3) to (C3) and the 180 ° rollover shown in FIGS. 5 (A4) to (C4) depending on the winding amount of the belt 235 by the lifting and lowering operation of the air cylinder 221. Can be executed at different positions. The winding amount of the belt 235 is determined by a count signal measured by an encoder SE200 (see FIG. 3 (A1)) attached to the rotary shaft 219. This count signal includes the dimensions of the wood W, the diameters of the rollers 232 and 232, the rollover angles (90 degrees (or -270 degrees), 180 degrees (or -180 degrees), and 270 degrees (or -90 degrees)). By calculating the measurement value of the count signal corresponding to the winding amount of the belt 235 determined from the above, rollover can be executed with high accuracy. Further, the rod of the air cylinder 221 is extended while the rollover units 210A to 210C are in the lowered position, and the roll of the rollover units 210A to 210C is raised to scoop up the wood W, and then the rod of the air cylinder 221 is contracted. Thus, rollover in the opposite direction such as -90 degrees rollover, -180 degrees rollover, and -270 degrees rollover can be executed.

  Here, as a direction switching valve for operating the air cylinder 221, as shown in FIG. 4C, a lowering mode for supplying to the rod side cylinder chamber and discharging from the head side cylinder chamber and a supply to the head side cylinder chamber are provided. A five-port three-position direction switching valve that has a rising mode for discharging from the rod-side cylinder chamber and a neutral mode for supplying both cylinder chambers and can be locked in the neutral mode is used. Thereby, based on the count value measured by the encoder SE200, the state is stopped at a predetermined angle such as 90 degrees (or -270 degrees), 180 degrees (or -180 degrees), and 270 degrees (or -90 degrees). be able to.

[7 Pre-cut processing control]
As shown in FIGS. 12 to 14, the precut processing control device 100 inputs precut data PCD (S110: PCD input) and performs processing in the side processing / full length cutting device 30 and the end processing / printing device 70. Data relating to the arrangement and operation direction of the tool is read (S120).

  Next, the material number n is set to 1 (S130), and the precut data PCD for the nth material is read (S140). Then, the side processing / full length cutting device data PCD1 is extracted from the precut data PCD for the nth input material (S150).

  Then, it is determined whether or not there is a side surface processing (first processing) that does not need to roll over the material in the initial input state in the side surface processing specified by the side surface processing / full length cutting device data PCD1 (S160). . If “YES” is determined, the side processing (second processing) in which the material in the initial input state needs to be rolled over exists in the side processing specified by the side processing / full length cutting device data PCD1. It is determined whether or not to perform (S170).

  When S170 also becomes “YES”, the first machining and the second machining and cutting data relating to the side machining / full length cutting are extracted (S180), and “input” → “first machining” → “reverse positioning” The processing order in the side surface processing / full length cutting device 30 is determined as “→” rolling over ”→“ input ”→“ second processing and full length cutting ”(S190).

  On the other hand, when S170 is “NO”, that is, when only the first machining is performed for the side machining / full length cutting, the first machining and cutting data are extracted (S200), and “input” → “First processing and full length cutting” and the processing order in the side surface processing / full length cutting device 30 are determined (S210).

  On the other hand, when S160 becomes “NO”, the side processing (second processing) in which the material in the initial input state needs to be rolled over to the side processing specified by the side processing / full length cutting device data PCD1. ) Exists (S220).

  When S220 becomes “YES”, the second machining and cutting data relating to the side machining / full length cutting are extracted (S230), and “positioning” → “rollover” → “input” → “second machining and total length” The cutting order in the side cutting / full length cutting device 30 is determined (S240).

  On the other hand, when S220 becomes “NO”, that is, when only full length cutting is performed, cutting data is extracted (S250), and “input” → “full length cutting” and processing in the side surface processing / full length cutting device 30 are performed. The order is determined (S260).

  When the processing order related to the processing by the side surface processing / full length cutting device 30 is determined in this way, it is determined whether or not it is a state to wait for execution of the side processing / full length cutting on the previously charged material (S270). In the case of n = 1, since the previously input material does not exist, S270 is determined as “YES”. In the case of n = 2, 3, 4,..., S270 may be “NO”. For example, when there is a return rollover of the material that has been previously input, the material input conveyor 20 is waited in a state immediately before the input. In this case, if there is no return rollover of the previously input material, S270 = YES, and the next material can be input to the material input conveyor 20. If rollover before loading is determined in the processing order for the material loaded on the material loading conveyor 20, rollover is performed immediately after loading, and the side surface processing / full length cutting device 30 for the previously loaded material is performed. Immediately after the machining by is completed, the charging starts. The determination in S270 not only avoids interference between materials, but also greatly contributes to shortening the cycle time.

  If the determination in S270 is “YES”, side processing / full length cutting is commanded in accordance with the processing order determined in the above-described processing (S280).

  As a result, when the first processing and the second processing exist, the “input” → “first processing” → “return” is performed by the material input conveyor 20, the side surface processing / full length cutting device 30, and the rollover device 200. Side surface processing and full length cutting are executed in the order of “positioning” → “rollover” → “input” → “second processing and full length cutting”. The control device 300 of the side surface processing / full length cutting device 30 transmits a completion signal to the precut processing control device 100 when the “second processing and full length cutting” is completed.

  In the case of only the first processing, the material processing conveyor 20 and the side processing / full length cutting device 30 perform side processing / full length cutting in the order of “input” → “first processing and full length cutting”. Executed. In this case, the control device 300 of the side surface processing / full length cutting device 30 transmits a completion signal to the precut processing control device 100 when the “first processing and full length cutting” is completed.

  Further, if only the second processing is performed, the positioning is performed by using the material input conveyor 20, the side surface processing / full length cutting device 30, and the rollover device 200, “positioning” → “rollover” → “loading” → “second processing and Side processing and full length cutting are performed in the order of “full length cutting”. The control device 300 of the side surface processing / full length cutting device 30 transmits a completion signal to the precut processing control device 100 when the “second processing and full length cutting” is completed.

  In the case of only cutting, full length cutting is executed in the order of “input” → “full length cutting” by the material input conveyor 20 and the side surface processing / full length cutting device 30. In this case, the control device 300 of the side surface processing / full length cutting device 30 transmits a completion signal to the precut processing control device 100 when the “full length cutting” is completed.

  When the precut machining control device 100 receives a completion signal from the control device 300 of the side surface machining / full length cutting device 30 (S300: YES), the precut machining control device 100 issues a removal command (S310). As a result, the processing material is taken out by the side surface processing / full length cutting device 30, the takeout conveyor 40, and the work material lateral transfer conveyor 50, and is laterally transferred in the material width direction, and the work material is input to the work material input conveyor 60. It is transferred to the position where it waits. The precut processing control device 100 calculates the orientation of the reference surface in this state (S320).

  Next, the edge processing / printing device data PCD2 is extracted from the precut data PCD read in S140 (S330).

  Then, with respect to the edge processing / printing specified by the edge processing / printing device data PCD2, the surface input to the material input conveyor 20 (reference surface at the time of material input) and the reference surface calculated at S320 (at the time of processing material input) It is determined whether or not the reference planes match (S340).

  If it is determined “YES” in S340, it is determined whether or not there is a process (first process) that does not require changing the orientation of the reference surface calculated in S320 (S350). If S350 is also determined to be “YES”, the processing (first processing) in which the orientation of the reference surface calculated in S320 needs to be changed for the end processing / printing specified by the end processing / printing device data PCD2 is continued. It is determined whether or not there is a process 2) (S360).

  If S360 is also “YES”, first processing and second processing and print data relating to edge processing / printing are extracted (S370), and “input” → “first processing and printing” → “ The processing order in the end portion processing / printing apparatus 70 is determined as "reverse positioning" → "rolling over" → "loading" → "second processing" (S380).

  On the other hand, when S340 is “YES”, S350 is also “YES”, and S360 is “NO”, that is, only the first processing is performed, the first processing and print data are extracted (S390). , “Input” → “first processing and printing”, and the processing order in the end processing / printing apparatus 70 is determined (S400).

  On the other hand, if “YES” in S340 and “NO” in S350, the second processing and print data are extracted (S410), and “input” → “print” → “reverse positioning” → “rollover” The processing order in the edge processing / printing apparatus 70 is determined in the order of “→“ input ”→“ second processing ”(S420). In the present embodiment, printing is performed on each member, and there is no first processing and second processing regarding end processing / printing, so S350 is “NO”. Can be considered as only processing that requires immediate rollover.

  If S340 is “NO”, it is determined whether or not there is a process (first process) that does not require changing the orientation of the reference surface calculated in S320 (S430). If it is determined “YES” in S430, the processing (first processing) in which the orientation of the reference surface calculated in S320 needs to be changed for the end processing / printing specified by the end processing / printing device data PCD2 is continued. It is determined whether or not there is processing 2) (S440).

  If S440 is also “YES”, the first processing and the second processing and print data regarding the end processing / printing are extracted (S450), and “input” → “first processing” → “return positioning” ”→“ rollover ”→“ input ”→“ second processing and printing ”and the processing order in the edge processing / printing device 70 is determined (S460).

  On the other hand, if S340 is “NO”, S430 is “YES”, and S440 is “NO”, that is, if only the first processing is performed, the first processing and print data are extracted (S470). Then, “processing”, “first processing” → “return positioning” → “rollover” → “input” → “printing” and the processing order in the end processing / printing device 70 are determined (S480).

  On the other hand, when S340 is “NO” and S430 is “NO”, the second processing and print data are extracted (S490), and “positioning” → “rollover” → “input” → “second” And processing order in the edge processing / printing apparatus 70 are determined (S500). In this embodiment, printing is performed on each member, and there is no first processing and second processing for end processing / printing. Therefore, when S430 is “NO” Can be considered as only processing that requires immediate rollover.

  When the processing order related to the processing by the end processing / printing device 70 is determined in this way, it is determined whether or not to wait for the end processing / printing on the previously loaded workpiece (S510). In the case of n = 1, since there is no processed material previously input, S510 is determined as “YES”. In the case of n = 2, 3, 4,..., as in the determination of S270, if there is a return rollover of the workpiece that has been previously input, S510 = NO and immediately before the input to the workpiece input conveyor 60. Wait in the state. On the other hand, even in the case of n = 2, 3, 4,..., If there is no return rollover of the previously input work material, S510 = YES, and the next work material is input to the work material input conveyor 60. can do. If there is a rollover before loading in the processing order determined for the workpiece loaded on the workpiece loading conveyor 60, the rollover is performed immediately after loading, and the end of the previously loaded workpiece When the processing by the processing / printing device 70 is completed, the charging is started immediately. This determination in S510 not only avoids interference between workpieces but also greatly contributes to shortening the cycle time.

  When the determination in S510 is “YES”, the edge processing / printing is commanded in accordance with the processing order determined in the above-described processing (S520).

  Thereby, when the reference surface when the material is input to the material input conveyor 20 and the reference surface when the material is input to the workpiece input conveyor 60 are the same, and the first processing and the second processing exist, By the workpiece loading conveyor 60, the edge processing / printing device 70, and the rollover device 600, “loading” → “first processing and printing” → “reverse positioning” → “rollover” → “loading” → “second” Edge processing and printing are executed in the order of “processing”. The control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when the “second processing” is completed.

  In addition, when the reference surface when the material is input to the material input conveyor 20 and the reference surface when the material is input to the workpiece input conveyor 60 are the same and only the first processing is performed, the processing input conveyor 60, Then, the edge processing / printing apparatus 70 executes the edge processing / printing in the order of “input” → “first processing / printing”. In this case, the control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when the “first processing and printing” is completed.

  Furthermore, when the reference surface when the material is input to the material input conveyor 20 and the reference surface when the material is input to the work material input conveyor 60 are the same and only the second processing is performed, the work material input conveyor 60 is used. , End processing / printing in the order of “loading” → “printing” → “reverse positioning” → “rollover” → “loading” → “second processing” by the end processing / printing device 70 and the rollover device 600. Is executed. The control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when the “second processing” is completed.

  If the reference surface when the material is loaded on the material loading conveyor 20 and the reference surface when the material is loaded on the workpiece charging conveyor 60 are different, and the first processing and the second processing are present, the processing material By the loading conveyor 60, the end processing / printing device 70, and the rollover device 600, “loading” → “first machining” → “reverse positioning” → “rollover” → “loading” → “second machining and printing” Edge processing and printing are executed in the order of. The control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when the “second processing and printing” is completed.

  In addition, when the reference surface when the material is input to the material input conveyor 20 is different from the reference surface when the material is input to the workpiece input conveyor 60 and only the first processing is performed, the processing input conveyor 60 and The edge machining / printing device 70 executes edge machining / printing in the order of “insertion” → “first machining” → “return positioning” → “rollover” → “insertion” → “printing”. In this case, the control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when “printing” is completed.

  Furthermore, when the reference surface when the material is input to the material input conveyor 20 is different from the reference surface when the material is input to the work material input conveyer 60 and only the second processing is performed, the work material input conveyor 60, The edge processing / printing device 70 and the rollover device 600 execute edge processing / printing in the order of “positioning” → “rollover” → “loading” → “second processing and printing”. The control device 700 of the edge processing / printing device 70 transmits a completion signal to the precut processing control device 100 when the “second processing and printing” is completed.

  When receiving the completion signal from the control device 700 of the edge processing / printing device 70 (S530: YES), the precut processing control device 100 determines whether or not the total length of the processed material is 1500 mm or more based on the precut data PCD. Determination is made (S610). If it is determined as “YES”, the orientation of the reference surface in a state where the processing by the edge processing / printing device 70 is completed and taken out to the discharge conveyor 80 is calculated (S620). The precut processing control device 100 determines whether or not “rollover” is included in the processing order in the side surface processing / full length cutting device 30 and whether or not “rollover” is included in the processing order in the end processing / printing device 70. The orientation of the reference surface, that is, the printing surface can be calculated.

  After the orientation of the reference surface at the time of discharge is calculated in this way, a rollover angle with the print surface facing upward is set (S630). Then, the discharging operation of “positioning” → “extrusion” → “rollover” → “discharge” is commanded to the discharge conveyor 80, the pushing device 85, the rollover device 800, and the discharging device 91 (S640). The “positioning” on the discharge conveyor 80 is determined according to the total length of the processed material specified by the precut data PCD. Further, “rollover” causes the rollover device 800 to execute a rollover operation corresponding to the rollover angle set in S630.

  On the other hand, when S610 is “NO”, that is, when the total length of the processed material is less than 1500 mm, a discharge operation of “positioning” → “inclined discharge” is commanded to the discharge conveyor 80 and the inclined discharge rail 95. (S650). The “positioning” on the discharge conveyor 80 is determined according to the total length of the processed material specified by the precut data PCD. Note that the processed material that has been discharged at an inclination does not necessarily face upward on the printing surface, but is a short and light member, so that there is no hindrance for the operator to lift and check the printing surface.

  When precut processing is completed for a certain member in this way, it is determined whether or not the precut data PCD read in S140 further relates to the next material (S660). If the next material remains (S660: YES), the material input order n is incremented to n + 1 and the process proceeds to S140 (S670). Then, when the pre-cut processing is finished for all the materials (S660: NO), this processing is finished.

The side cutting / full length cutting device 30 performs end cutting, side hole drilling, and full length cutting. In this example, as the side processing, the surface is made of three drift pins pierced by a drill TL34, two bolt insertion holes and one drift pin piercing hole for the middle, Three drift pin driving holes for the end portions are formed.

[10 Material rollover positioning]
[10.1 Sensor placement of material loading conveyor]
As shown in FIG. 19, an intermediate rollover unit 210 </ b> B is installed on the material loading conveyor 20 in the middle of the entire length of the material loading conveyor 20. Then, with respect to the intermediate rollover unit 210B, the first installation interval L21 is opened to install the front end rollover unit 210A, and the second installation interval L22 is opened to install the rear end rollover unit 210C. Has been. The “installation interval” here is the distance between the centers of the rollover devices.

  In this embodiment, a material having a minimum material length = 720 mm to a maximum material length = 6500 mm can be input, and the installation intervals of the three rollover units 210A to 210C are set to L21 = 500 mm, L22 = 1100 mm, L21 + L22 = It is set to 1600 mm. In other words, the installation intervals L21 and L22 are set so that L21 is shorter than the minimum material length, L22 is slightly more than twice L21, and L21 + L22 is slightly more than three times L21. The distances LP27, LP28, and LP29 to the installation positions of the three rollover units 210A, 210B, and 210C with respect to the tip position [21] of the material loading conveyor 20 are LP27 = 2000 mm, LP28 = 2500 mm, LP29 = 3600 mm. It is set to become.

  Further, the front end position [21] of the material loading conveyor 20, the intermediate position [22] between the front end position [21] and the rollover unit 210A on the front end side, and the intermediate position between the rollover unit 210A on the front end side and the intermediate rollover unit 210B [ 23], an intermediate position [24] between the intermediate rollover unit 210B and the rear end rollover unit 210C, and an intermediate position [25] between the rear end rollover unit 210C and the rear end position [26] of the material loading conveyor 20. ], The first to fifth photoelectric sensors S21 to S25 are installed.

  Here, in this embodiment, the installation interval LS21 between the first photoelectric sensor S21 and the second photoelectric sensor S22, the installation interval LS22 between the second photoelectric sensor S22 and the third photoelectric sensor S23, and the third photoelectric sensor S23. The installation interval LS23 of the fourth photoelectric sensor S24 and the installation interval LS24 of the fourth photoelectric sensor S24 and the fifth photoelectric sensor S25 are LS21 = 900 mm, LS22 = 1300 mm, LS23 = 800 mm, and LS24 = 1000 mm, respectively. .

  When the material is fed laterally in the material width direction from the material loading lateral transfer conveyor 10 to the material loading conveyor 20, the material is fed at the center of the four chains 11 to 14 of the chain slasher. Then, the operator loads the material into the material transfer lateral transfer conveyor 10 with visual alignment. The distance L11 between the central chains 12-13 is 700 mm, and the distance L12 between the left and right chains 11-14 is 2900 mm. The center of the center chain 12-13 coincides with the fourth photoelectric sensor S24, and the fourth photoelectric sensor S24 is positioned at the center of the center rollover unit 210B and the rear end rollover unit 210C. ing.

  Here, the material Wmin (material length LW = 720 mm) with the minimum material length at the time of loading is straddled across both the front side rollover unit 210A and the intermediate rollover unit 210B where the installation interval L21 = 500 mm. By doing so, the center of gravity is located between both rollover units 210A-210B, and rollover can be executed without breaking the balance. In addition, the material Wmax (material length LW = 6500 mm) having the maximum material length at the time of loading is set to three rollover units so that the center of gravity is positioned between the intermediate rollover unit 210B and the rollover unit 210C on the rear end side. Rolling over can be executed without breaking the balance by straddling 210A to 210C.

  The first to fifth photoelectric sensors S21 to S25 are of the reflective type that is turned on when a material is in front of them. In putting the material, as shown in FIG. 19, the material is placed so that the center of the length is aligned with the center of the two central chains 12 and 13 of the material feeding lateral transfer conveyor 10. If the material is correctly placed, the material having a material length of 1300 mm or more straddles at least the intermediate rollover unit 210B and the rollover unit 210C on the rear end side when it is loaded into the material loading conveyor 20 by the lateral transfer in the material width direction. The center of gravity is located between the rollover units 210B and 210C. Therefore, it is possible to roll over without carrying out positioning conveyance in the longitudinal direction while being loaded onto the material loading conveyor 20 by lateral transfer in the material width direction.

  On the other hand, a material having a material length of 1100 mm or less does not straddle the intermediate rollover unit 210 </ b> B and the rollover unit 210 </ b> C on the rear end side when it is loaded into the material loading conveyor 20 by the lateral transfer in the width direction. Can not. A material having a material length of 1200 mm can be rolled over as long as it is accurately placed on the material loading lateral transfer conveyor 10, but does not straddle two rollover units if there is some deviation. Therefore, even in this case, the roll cannot be rolled over as it is.

  Here, the material placed so that the center of the length comes to the center of the center two chains 12 and 13 with respect to the material loading lateral transfer conveyor 10 is loaded into the material loading conveyor 20 by the horizontal transfer in the material width direction. When the material length is LW = 6500 mm, the first to fifth photoelectric sensors S21 to S25 are all turned on. When the material length is LW = 3000 mm, the first and second photoelectric sensors S21 are used. , S22 are OFF, and the third to fifth photoelectric sensors S23 to S25 are turned ON. If the material length is LW = 1600 to 2000 mm, the first, second, and fifth photoelectric sensors S21, S22, and S25 are turned off, and the third and fourth photoelectric sensors S23 and S24 are turned on. If the material has a length LW of 720 to 1500 mm, only the fourth photoelectric sensor S24 is turned on.

In this embodiment, in addition to commercially available fixed-size materials, the remaining materials left over by processing that exceed the minimum material length are input as materials. In this case, the material is not necessarily a 1600 mm material, but as shown in FIG. 19, the material is loaded so that the center of the length of the material coincides with the center of the two chains 12 and 13 in the middle of the material feeding lateral transfer conveyor 10. Therefore, the ON / OFF state of the sensor becomes the following five sensor patterns, and the material length LW can be narrowed down to the range shown in Table 1.

  Here, the front end side rollover unit 210A is between the second photoelectric sensor S22 and the third photoelectric sensor S23, and the intermediate rollover unit 210B is between the third photoelectric sensor S3 and the fourth photoelectric sensor S4. The side rollover unit 210C exists between the fourth photoelectric sensor S24 and the fifth photoelectric sensor S25.

[10.2 Material loading rollover positioning]
Therefore, as a result of putting the material so that the center of gravity of the material comes around the fourth photoelectric sensor S24, for the sensor patterns 1 and 2, the material straddles the three rollover units 210A to 210C, and the material Since the center of gravity is between the rollover units 210A and 210C at both ends, the rollover without breaking the balance can be executed as it is even if the material length is not accurately grasped.

  In the case of the sensor pattern 3, the material straddles the two rollover units 210B and 210C, and the center of gravity of the material is between the rollover units 210B and 210C at both ends. Even if it is not grasped, rollover without breaking the balance can be executed as it is.

  On the other hand, in the sensor patterns 4 and 5, since the material does not straddle a plurality of rollover units at the time when the material is input, it is difficult to rollover without breaking the balance as it is. Therefore, in this embodiment, in the case of the sensor patterns 4 and 5, the material is rolled over after performing the following positioning operation shown in FIG.

[Transfer pattern 21]
First, the material is conveyed in the longitudinal direction in the forward direction. When the third photoelectric sensor S23 is switched from OFF to ON, it is further advanced by 400 mm. This additional 400 mm advance is controlled by a timer. That is, an additional 400 mm of advance can be performed by conveying the material in the longitudinal direction in the forward direction and further moving forward for a predetermined time after the third photoelectric sensor S23 is switched from OFF to ON. As shown in the drawing, the material of LW = 720 mm to 1200 mm spans the front end side rollover unit 210A and the intermediate rollover unit 210B, and the center of gravity is located inside these two rollover units 210A and 210B. be able to. Thereafter, if the rollover device 200 is driven, the material can be smoothly rolled over without breaking the balance.

  Even if the transfer pattern 21 is executed and the third photoelectric sensor is turned on, the fourth photoelectric sensor S24 may remain turned on even if an additional 400 mm is advanced. This is a case where the sensor pattern 4 or the sensor pattern 5 is detected by a material having LW = 1200 mm to 1600 mm.

[Transfer pattern 22]
