[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a processing method for continuously cutting a single plate delivered from a veneer lace, and a processing apparatus used for carrying out the processing method.
[0002]
[Prior art]
When a log is turned by veneer lace, an irregular discontinuous veneer with defects (unnecessary parts) at the front and rear ends from the outer periphery of the original irregular log, and then the log becomes substantially cylindrical. In this case, continuous single plates with defects near the tip are sent out respectively. For example, in order to save labor and improve efficiency in subsequent processes such as the drying process and recumbent process, discontinuous single sheets are used. For the plate, the process of cutting out the defects at the front and rear ends, and for the continuous single plate, along with the process of cutting out the defects, the desired fixed width (also defined as the fixed length) in the direction orthogonal to the fibers of the single plate. Each process is required to be performed continuously without stopping the transfer of the veneer in order not to disturb the operation of the veneer lace. The applicant has previously described "Single-plate continuous cutting method and apparatus" (Japanese Examined Patent Publication 56). As disclosed in 13603 JP) developed a processor and processing method corresponding to those requests, and contributed to the rationalization of veneer processing steps.
[0003]
The outline of the processing method is as follows. A continuous sized cutting discriminating process for continuously cutting unnecessary portions of a veneer, and an effective veneer sent from the continuous sized cutting discriminating process are packed together with a predetermined length (general In particular, a continuous fixed cutting discriminating and conveying step for discriminating and conveying a preceding effective veneer group and a subsequent effective veneer group by continuously cutting at regular intervals every 220 cm), and the continuous fixed cutting and discriminating conveying step The effective single plate group delivered from the machine is transported to a predetermined position and deposited, and the deposition process is a series of processes so that the above-mentioned requirements can be met. A pair of upper and lower transport rollers that also serve as a body, and the blade tip is directed in the opposite direction to the traveling direction of the veneer, and the blade tip is rotated one-way alternately in a timely manner within the section where each blade contacts the outlet peripheral surface.

The treatment method can be implemented by comprising two successive deposition mechanisms.
[0004]
[Problems to be solved by the invention]
According to the processing method and the processing apparatus as described above, not only continuous cutting processing is possible, but all the single plates sent from the veneer lace can be stacked by being cut to a predetermined standard, While it is possible to easily transfer the piles to the subsequent process and take out each single plate group from the piles, it has the advantage that it is effective for labor saving and efficiency of the whole single plate processing process. Since the two cutting mechanisms are provided in series, there is a problem that the equipment cost of the entire apparatus is increased, and the effective veneer group is finally incorporated into the effective veneer group in order to cut the effective veneer group to a predetermined standard. Since it is necessary to divide almost all of the effective veneer into two sheets, in the subsequent recumbent process, etc., extra shaped scraps that are originally useless are generated on both sides of the divided part, and as a result There is a difficulty in reducing the yield of a single plate, and further two cutting mechanisms When a cutting mechanism having a consumable member whose consumption increases in proportion to the operational state is used, such as a transport roller that also serves as the blade receiver or a cutting blade, the consumable member is updated.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail together with an example of the embodiment illustrated in the drawings. However, if it is mentioned in advance, the veneer has a property that it shrinks unevenly with drying and tends to be distorted. When cutting out the defects of the single veneer to be sent out, if all of the defects are cut out as unnecessary parts, drying distortion will occur when the effective veneer is finally shaped into a rectangle in the recumbent process after the drying process. Since there is a possibility that extra shaping scraps may be generated only in the part of the veneer, it is usually not necessary to cut out all the defects of the veneer as unnecessary parts, for example, to leave some defects on the front and rear ends of the effective veneer. Or, for example, a relatively narrow defect or gap is usually passed through without being processed even if it is detected, and the example shown is also processed in accordance with such practice. . There are various common names indicating dimensions that do not meet the standard, for example, irregular scale, sizing, end scale, loose dimension, etc., but the irregular scale is used for convenience in the description of the present invention.
[0013]
FIG. 1 is a schematic side view of a single-plate processing apparatus and a deposition apparatus connected to the processing apparatus according to the present invention, and FIG. 2 is a schematic backside explanatory view of the deposition apparatus illustrated in FIG.
[0014]
In the figure, reference numeral 2 denotes a transfer conveyor, which is omitted from illustration, but directly (or indirectly via the lower conveying roller 4b) by the same drive source as that of the cutting mechanism 4 described later. It can be rotated, or it can be rotated in the direction of the arrow shown in the figure at a speed synchronized with the veneer race by obtaining the drive of an appropriate dedicated drive source (not shown) such as a motor / servo motor with a speed reducer. The single plate 1 delivered from a race (not shown) is transferred to a cutting device H described later.
[0015]
Reference numeral 3 denotes a single plate detection mechanism that constitutes a part of the cutting device H, and has a roller 3a positioned on the terminal end of the transfer conveyor 2 and swings according to the thickness of the single plate 1 A plurality of single plate detectors 3c such as limit switches and photoelectric switches having contact points 3d that are turned ON / OFF in accordance with the swing of the swing arm 3b in a direction orthogonal to the traveling direction of the single plate 1. An unnecessary portion of the single plate 1 is detected in front of the cutting mechanism 4 described later, and a detection signal is transmitted to the control mechanism 13 described later.
[0016]
More specifically, the contacts 3d of the single plate detectors 3c are normally connected in parallel in the ON state, and are all connected with the swing of the swing arm 3b corresponding to the thickness of the single plate 1 that has arrived. When the contact 3d is turned off, it is detected that an unnecessary part of the veneer 1 has passed and reached an effective part. On the other hand, when any one contact 3d is turned on, the veneer 1 is activated. It is detected that the portion has passed and reached an unnecessary portion, and a detection signal is transmitted to the control mechanism 13 described later.
[0017]
4 is a cutting mechanism that constitutes a main part of the cutting device H, and is rotated in the direction of the arrow shown in the drawing at a speed synchronized with the veneer race by an appropriate drive source (not shown) such as an electric motor with a reduction gear, a servo motor or the like. A pair of upper and lower transport rollers 4a and 4b, and the blade tip is directed in the direction opposite to the traveling direction of the veneer 1 and the blade tip is alternately rotated in one direction in the section where the blade contacts the peripheral surface of each of the transport rollers 4a and 4b. It comprises a cutting blade 5 provided as possible, and a rotating mechanism 11 such as a fluid cylinder and a cam for alternately rotating the cutting blade 5 one way via a fulcrum shaft 5a. The cutting blades 5 are alternately rotated one way when necessary, and a scrap cutting operation for continuously cutting unnecessary portions of the single plate 1 as waste S, and by continuously cutting the single plate 1 for each standard length. The operation of sorting up and down is performed.
[0018]
Although not shown in the drawings, if a large number of oblique grooves are formed on the outer peripheral surface of the pair of upper and lower transport rollers in a distributed manner, the single plate transport force is enhanced and the cutting of the single plate is stabilized. Furthermore, if a large number of circumferentially extending grooves are formed at opposite positions on the outer peripheral surface of the pair of upper and lower transport rollers, wear of the cutting edge of the cutting blade in the groove portion is significantly reduced. As a result, the life of the cutting blade is extended, and the biting property of the cutting edge of the cutting blade with respect to the single plate is maintained for a long time, so that the cutting of the single plate is further stabilized, which is more effective.
[0019]
Numerals 6 and 7 are conveying conveyors used as conveying mechanisms constituting conveying paths a and b of two effective upper and lower single plates. The upper conveying conveyor 6 is immediately after the cutting device H, and the lower conveying conveyor. 7 are respectively provided with an appropriate space to form a waste discharge path c between the cutting device H and the front half 6a of the upper conveyor 6 and the lower conveyor 7 The speed is synchronized with the veneer race by an appropriate drive source (not shown) such as an electric motor / servo motor with a reduction gear, and the second half 6b of the upper conveyor 6 is a variable speed such as an electric motor / servo motor with a transmission. A speed synchronized with the veneer lace by a drive source (not shown) of the mold, and a speed suitable for stacking the cut-cut veneer on another fixed veneer transported by the lower transport conveyor 7 Respectively, at two speeds示矢 order to rotate the sign direction controller is controlled by the (not shown), is transported to the deposition apparatus 14 to be described later veneer sent from the cutting device H.
[0020]
More specifically, the second half 6b of the upper conveyor 6 always rotates at a speed synchronized with the veneer lace when the cutting device H performs the scrap cutting operation, and the processed veneer is conveyed as it is in the lower conveyor. On the other hand, when the cutting device H performs the cutting operation for each standard length so as to be transferred to the conveyor 7, it is synchronized with the veneer race until the standard cut single plate is transferred from the front half 6 a. In addition, after the veneer is transferred from the front half 6a, the veneer is rotated at a speed suitable for stacking the veneer on another veneer cut by a fixed length conveyed by the lower conveyor 7. As shown by the dotted lines, the single plates that have been cut in a fixed length are controlled so as to be sequentially superposed on the lower conveyance conveyor 7.
[0021]
A damper 8 is used as an opening / closing member, and is provided in the vicinity of the start end of the lower transfer conveyor 7 so as to be swingable around a support shaft 8a. The operation mechanism 12 such as a fluid cylinder / cam is operated. Thus, it swings alternately between the position indicated by the solid line and the position indicated by the dotted line, and opens and closes the waste discharge path c when necessary.
[0022]
9 is a standard measuring mechanism that constitutes a part of the cutting device H, and is positioned at an appropriate position in the course of the conveying path ab of the effective single plate, more specifically, the cutting edge of the cutting blade 5 of the cutting mechanism 4 A fixed distance measuring device 9a, 9b such as a limit switch / photoelectric switch, etc., is provided at a required distance from the front end of the single plate that has passed the cutting edge position of the cutting blade 5 to reach a position where it can be measured. Is directly measured and a measurement signal is transmitted to the control mechanism 13 described later.
[0023]
Reference numeral 13 denotes a control mechanism, and until the width of the single plate 1 arriving at the cutting device H reaches a width that requires fixed cutting, the control mechanism 13 is operated via the operation mechanism 12 based on the detection signal from the single plate detection mechanism 3. Then, the damper 8 is opened to open the waste discharge path c, and the waste cutting operation for cutting the unnecessary portion of the single plate 1 as the waste S is performed, and the width of the incoming single plate 1 requires a regular cutting. After reaching the width, the damper 8 is closed via the actuating mechanism 12 based on the measurement signal from the standard measuring mechanism 9 regardless of whether or not there is an unnecessary portion in the subsequent single plate 1. The cutting device H is operated so as to block the waste discharge path c and perform only the cutting operation for each standard length.
[0024]
The control mode of the control mechanism 13 will be described in more detail along the operation mode of the cutting device H. When the cutting device H is started, the cutting blade 5 is made to wait at the position indicated by the dotted line via the rotating mechanism 11. Then, the damper 8 is controlled to stand by at a position indicated by a solid line via the operation mechanism 12. Eventually, with the arrival of the veneer 1 from the veneer race, the contacts 3d of all the veneer detectors 3c are turned off, and a detection signal of an unnecessary portion on the front end side of the veneer 1 is transmitted from the veneer detection mechanism 3. Then, in response to the time when the unnecessary portion passes the position of the cutting edge of the cutting blade 5, the cutting blade 5 is controlled to rotate one way to the position indicated by the solid line via the rotation mechanism 11. By the cutting operation of the cutting blade 5, an unnecessary portion on the front end side of the single plate is cut as waste S and discharged to the waste discharge path c, and the single plate 1 is carried into the upper conveyance path a. Next, before the tip of the single plate 1 reaches the position of the standard measuring instrument 9a, the contact 3d of any one single plate detector 3c is turned on, and the single plate 1 is moved from the single plate detection mechanism 3 to the rear of the single plate 1. When the detection signal of the unnecessary portion on the end side is transmitted, the cutting blade 5 is moved to the position indicated by the dotted line via the rotation mechanism 11 in correspondence with the timing when the unnecessary portion reaches the position of the cutting edge of the cutting blade 5. Control to rotate one way. By the cutting operation of the cutting blade 5, an unnecessary portion on the rear end side of the single plate is cut out as waste S and discharged to the waste discharge path c, and the single plate 1 is left as it is with the upper transport conveyor 6 and the lower transport conveyor. 7 to the deposition apparatus 14 to be described later.
[0025]
However, even when a detection signal for an unnecessary portion on the front end side of the single plate 1 is transmitted from the single plate detection mechanism 3, a period until a detection signal for an unnecessary portion on the rear end side is transmitted next is desired. If it is less than the minimum period, it means that the width of the single plate is less than the desired width (minimum width). Such a narrow single plate is not practical even if it is obtained. Since there is a risk of causing troubles such as clogging and clogging in the subsequent drying process, it is practical to stop the cutting operation of the cutting blade as described above and discharge all of the waste as waste to the waste discharge path c. Therefore, in the control described in the previous stage, the period from when the detection signal for the unnecessary part on the front end side is transmitted to when the detection signal for the unnecessary part on the rear end side is transmitted is less than the desired minimum period. Is preferably used in combination with a control that exceptionally stops the cutting operation of the cutting blade, In combination a Such control also at an example.
[0026]
On the other hand, as described above, after the unnecessary portion on the front end side of the single plate is cut as the scrap S, before the detection signal of the unnecessary portion on the rear end side of the single plate 1 is transmitted from the single plate detection mechanism 3. When the tip of the single plate 1 reaches the position of the standard measuring instrument 9a and a measurement signal is transmitted from the standard measuring mechanism 9, the damper 8 is closed via the operating mechanism 12, and the waste is discharged. The path c is closed, and the cutting blade 5 is controlled to rotate one way to the position indicated by the solid line via the rotation mechanism 11. By the cutting operation of the cutting blade 5, the preceding single plate 1 is cut at a fixed position and is subsequently conveyed by the upper conveyance conveyor 6, and the subsequent single plate 1 is moved to the lower conveyance path b. It is brought in. Then, after controlling the cutting blade 5 once to perform a regular cutting operation in this way, even if a detection signal of an unnecessary portion is transmitted from the single plate detection mechanism 3 thereafter, the cutting blade 5 based on the detection signal. The cutting operation is not performed, and the blockage of the waste discharge path c by the damper 8 is controlled to continue until the cutting device H is returned to the starting state again.
[0027]
Eventually, when the tip of the veneer 1 carried into the lower conveyance path b reaches the position of the standard measuring instrument 9b and a measurement signal is transmitted from the standard measuring mechanism 9, the rotation mechanism 11 is used. The cutting blade 5 is controlled to rotate one way to the position indicated by the dotted line. The single plate 1 is cut at a fixed position by the cutting operation of the cutting blade 5 and is subsequently transported by the lower transport conveyor 7, and the subsequent single plate 1 is transported to the upper transport path a. The Thereafter, until the arrival of the single plate 1 is interrupted, control is performed so as to repeat the same standard cutting operation based on the measurement signal from the standard measurement mechanism 9.
[0028]
For example, if the arrival of a single plate is interrupted, the single plate detection mechanism will not detect the presence of the single plate at all even if a certain period of time elapses, or the cutting blade will not operate even within a certain period, for example. A phenomenon different from the normal operating state occurs. Therefore, based on such a phenomenon or the like, it is detected (judged) that the arrival of the single plate 1 has been stopped, and then the cutting device H is brought into the starting state again in preparation for the arrival of another single plate 1 next. In order to return, the turning mechanism 11 and the operating mechanism 12 are also controlled so that the cutting blade 5 is in the standby position at the position indicated by the dotted line and the damper 8 is at the position indicated by the solid line.
[0029]
Reference numeral 14 denotes a semi-manual type deposition apparatus, which is opposed to the upper and lower sides in the vertical direction so that the veneer 1 is clamped from the upper and lower sides only at one end (preferably FIG. 2). The upper side is positioned closer to the end of the veneer than the lower side), and at a speed synchronized with the lower transfer conveyor 7 by an appropriate drive source (not shown) such as a motor with a reduction gear or a servo motor. It comprises a pair of upper and lower sandwiching conveyors 14a and 14b that can be rotated in the direction of the arrow in the figure, and a stacking table 14c that can move up and down freely and can maintain the height of a single plate stacking surface substantially constant. The veneer 1 transferred from the lower conveyor 7 is nipped and conveyed in a cantilever state, and each time the operator pulls out the veneer 1 from the nipping conveyors 14a and 14b and drops it, the veneer 1 is substantially constant. Receiving and depositing at a height Deposited as 10.
[0030]
A preferred single plate processing apparatus according to the present invention is configured as described above, for example, and the operations performed by the configuration will be sequentially described below with reference to a plane development explanatory view of a single plate delivered from a veneer race. explain.
[0031]
FIG. 3 is a plan development explanatory view of a single plate sent from a veneer lace when a standard log is turned. The cutting blade 5 of the cutting device H is at a position indicated by a dotted line, and the damper 8 is a position indicated by a solid line. In the state of waiting for each time (starting up), even if the first triangular plate 1 as illustrated on the upper right side of FIG. 3 arrives at first, it is not detected by the single plate detection mechanism 3, and further desired. Since the control mechanism 13 controls the cutting operation of the cutting blade 5 to be exceptionally suspended even if a single plate 1 less than the width of the single plate 1 arrives, the single plate 1 is a waste discharge path as waste S. discharged to c.
[0032]
Next, when the single plate 1 having a width exceeding the desired width as illustrated from the upper left side to the lower right side in FIG. 3 arrives, the unnecessary portion on the front end side and the unnecessary portion on the rear end side from the single plate detection mechanism 3 are separated. Based on the detection signal, the control mechanism 13 controls the cutting blade 5 to alternately rotate one way each time. Therefore, unnecessary portions at the front and rear ends of each single plate 1 are cut off as scrap S at the position of the cutting line K. In addition to being discharged to the waste discharge path c, the veneer 1 (random veneer) is conveyed to the deposition device 14 via the upper conveyor 6 and the lower conveyor 7 to be deposited.
[0033]
Next, when the continuous single plate 1 as illustrated from the lower center to the lower left side in FIG. 3 arrives, the control mechanism 13 causes the cutting blade 5 based on the detection signal of the unnecessary portion on the front end side from the single plate detection mechanism 3. Is controlled to rotate one way to the position indicated by the solid line, so that the unnecessary portion on the front end side is cut off as waste S at the position of the cutting line K and discharged to the waste discharge path c. It is carried into the upper conveyance path a. And, as shown in the figure, there is an unnecessary portion, a chip Z having a width sufficient for excision in the present example, at a position separated from the tip of the veneer 1 by a width less than a standard width, and the front end of the chip Z is When the position of the single plate detection mechanism 3 is reached, the contact 3d of at least one single plate detector 3c is turned on, and a detection signal of an unnecessary portion on the rear end side is transmitted from the single plate detection mechanism 3 to control the single plate detection mechanism 3 Since the mechanism 13 controls the cutting blade 5 to rotate one way to the position indicated by the dotted line, the veneer 1 is cut at the position of the cutting line K, and the veneer 1 (random veneer) is transported in the upper stage. It is conveyed to the deposition apparatus 14 via the conveyor 6 and the lower conveyance conveyor 7, and is deposited. On the other hand, the portion having the chip Z is carried into the waste discharge path c. When the rear end of the chip Z eventually reaches the position of the single plate detection mechanism 3, the contacts 3d of all the single plate detectors 3c are connected. Since the detection signal of the unnecessary part on the front end side is transmitted from the single plate detection mechanism 3 and the control mechanism 13 controls the cutting blade 5 to rotate one way to the position indicated by the solid line, the chip Z is included. An unnecessary part is cut | disconnected in the position of the cutting line K, and is discharged | emitted as the waste S to the waste discharge path c.
[0034]
Next, the veneer 1 that has only the chipping Z1 that does not require excision arrives (or a veneer that does not have defects such as chippings and nodal holes has arrived), and an unnecessary portion on the rear end side from the veneer detection mechanism 3 If the tip of the veneer 1 reaches the position of the standard measuring instrument 9a before the detection signal is transmitted, and the measurement signal is transmitted from the standard measuring mechanism 9, the control mechanism 13 operates the operating mechanism 12. The damper 8 is closed via the plug, the waste discharging path c is closed, and the cutting blade 5 is controlled to rotate one way to the position indicated by the solid line via the rotation mechanism 11. Is cut at a standard position and is subsequently conveyed by the upper conveyor 6 and the subsequent single plate 1 is carried into the lower conveyance path b. After that, the control mechanism 13 does not perform the cutting operation of the cutting blade 5 based on the detection signal of the unnecessary part from the single plate detection mechanism 3, and only performs the standard cutting operation based on the measurement signal from the standard measuring mechanism 9. Since it is controlled to repeat, the veneer 1 is sequentially cut into fixed lengths and alternately loaded into the upper conveyance path a and the lower conveyance path b, and on the lower conveyance conveyor 7 every two sheets. Superposed, transported to the deposition device 14 and deposited.
[0035]
On the other hand, although it has not been seen so much recently, when turning a very thick log, following the discontinuous veneer 1 having a width less than the standard as illustrated from the upper center to the lower right end of FIG. 4, a discontinuous single plate 1 having a width exceeding the standard length as illustrated in the lower center right side of FIG. 4 is sent out. When such a single plate 1 arrives, the single plate detection mechanism 3 After the unnecessary part on the front end side is excised as waste S on the basis of the detection signal of the unnecessary part on the front end side, before the detection signal of the unnecessary part on the rear end side is transmitted, Since the tip reaches the position of the standard measuring instrument 9a and a measurement signal is transmitted from the standard measuring mechanism 9, the single plate 1 is cut at the standard position, and according to the control mode, After that, since only the cutting operation for each standard is controlled, the lower center in FIG. As shown in the example, the discontinuous single plate 1 and the continuous single plate 1 have a width sufficient to cut away unnecessary portions at the front and rear ends of the boundary E between the continuous single plate 1 and the continuous single plate 1. The unnecessary portion including the chip Z is not cut off as a result, and a process of remaining on the obtained single plate (fixed single plate) is performed.
[0036]
Furthermore, even after the veneer that has no unnecessary portion has arrived once, for example, due to the presence of cracks in the core of the raw wood, there are significant cracks as illustrated in the upper part of FIG. Due to the arrival of the veneer 1 having W or, for example, the loss of a part of the raw wood in the course of turning, the width sufficient for cutting newly generated as illustrated in the lower part of FIG. Although the single plate 1 having the chipped Z may arrive, according to the control mode, even when such a single plate 1 arrives, unnecessary portions at the front and rear ends of the remarkable crack W The unnecessary part including the chip Z having a width sufficient for excision is not cut off as a result, but is left on the obtained single plate (fixed single plate).
[0037]
However, even if a processing method that leaves some unnecessary portions (defects) to be excised, if compared to the conventional method, the proportion of unnecessary portions remaining is compared to the total amount of veneer to be obtained. In the subsequent steps, there is not so much that there is no particular problem, so there is no particular problem in practical use. According to such a processing method, the veneer lace is generally sent out with a relatively simple configuration. A veneer can be processed smoothly.
[0038]
However, it is preferable not to leave unnecessary portions on the obtained veneer if possible. More unnecessary portions can be removed by performing another processing method that is a slightly modified configuration of the processing method. The processing apparatus illustrated in FIGS. 1 and 2 can also be used in another processing method for removing more unnecessary portions by slightly changing the configuration of the control mechanism.
[0039]
Specifically, the configuration of the control mechanism 13 of the processing apparatus illustrated in FIGS. 1 and 2 is changed to the single plate detection mechanism 3 until the width of the single plate 1 arriving at the cutting device reaches a width that requires a regular cutting. On the basis of the detection signal from, the damper 8 is opened via the operation mechanism 12 to open the waste discharge path c, and perform the waste cutting operation for cutting unnecessary parts of the single plate 1 as waste S. When the width of the single plate 1 to be reached reaches the width that requires the standard cutting, the damper 8 is closed via the operating mechanism 12 based on the measurement signal from the standard measuring mechanism 9, and the waste discharge path c In addition, a single cutting operation is always performed once, and thereafter, the subsequent single plate 1 is based on the detection signal from the single plate detection mechanism 3 and the measurement signal from the fixed measurement mechanism 9. When there is no unnecessary portion, the single plate 1 flowing into the passage a of the upper effective single plate When there is an unnecessary part in the most advanced part and when there is an unnecessary part in the veneer 1 that flows into the passage b of the lower effective veneer, the waste discharge path c is kept closed for each scale. Only when there is an unnecessary portion to be cut off at a portion other than the most distal portion of the veneer 1 that performs the cutting operation and flows into the passage a of the upper effective veneer, The damper 8 is opened to open the waste discharge path c, and the control is performed so as to perform a waste cutting operation for cutting unnecessary portions of the single plate 1 as waste S.
[0040]
The operation performed by the configuration modified as described above will be described in order with reference to the plan development diagram of the single plate as in the previous example. The single plate to be processed is as shown in the example of FIG. In this case, the order in which the detection signal from the single plate detection mechanism 3 and the measurement signal from the standard measurement mechanism 9 are transmitted for the single plate 1 and the control mode of the control mechanism 13 are the same as the previous example. The effect exerted is also exactly the same as that of the previous example, and as long as the single plate having such a form is targeted, there is no difference in the effect due to the difference in configuration. On the other hand, the example of FIG. 6 is an example in which the veneer 1 having the same form as that of the example of FIG. 4 is an object of processing, but a difference in part of the operation occurs as described later due to the difference in configuration. .
[0041]
That is, the single plate 1 having a width less than the desired width as illustrated in the upper right part of FIG. 6 is processed to be discharged as waste S into the waste discharge path c, and then illustrated in the lower central right part of FIG. Until the discontinuous single plate 1 having a width exceeding the standard is processed to be cut at a standard position, the detection signal from the single plate detection mechanism 3 and the standard measurement are measured. Since the order in which the measurement signals are transmitted from the mechanism 9 and the control mode of the control mechanism 13 are the same as those of the previous example, the effect exerted is the same as that of the previous example. When processing the veneer 1 including the boundary E between 1 and the subsequent veneer 1, the control mechanism 13 also controls the cutting operation at the standard position (for the sake of safety, Even if the single plate detection mechanism 3 detects unnecessary portions at the front and rear ends of the boundary E and transmits a detection signal. Veneer 1 including the boundary E, since flows into the passage b of the lower effective veneer, the control mechanism 13 does not perform the control of debris ablation operation of excising unnecessary portions of the front and rear ends of the boundary E as scrap S). However, as illustrated on the left side of the lower stage of FIG. 6, an unnecessary part to be excised other than the most distal part of the veneer 1 flowing into the passage a of the upper effective veneer is sufficient for this example. When there is a chip Z having a width, the control mechanism 13 provisionally sets the damper 8 based on the fact that the single plate detection mechanism 3 detects the passage of the front and rear ends of the chip Z and transmits a detection signal. Since the scrap cutting operation is controlled by the cutting blade 5, the unnecessary portion including the chip Z is cut as the scrap S and discharged to the waste discharge path c.
[0042]
Further, for example, as illustrated in the upper center of FIG. 7, even if there is a significant crack W in the single plate 1 flowing into the passage b of the lower effective single plate, the control mechanism 13 is In the case where there is a significant crack W in the veneer 1 flowing into the passage a of the upper effective veneer as illustrated in the lower center of FIG. The control mechanism 13 tentatively opens the damper 8 based on the fact that the single plate detection mechanism 3 detects the passage of the remarkable crack W through the front and rear ends and transmits a detection signal. Since the scrap cutting operation is controlled by 5, unnecessary portions at the front and rear ends of the remarkable crack W are cut as scrap S and discharged to the waste discharge path c.
[0043]
Furthermore, even if a chip Z having a width sufficient to be cut out exists in the veneer 1 flowing into the passage b of the lower effective veneer, as illustrated in the upper center right side of FIG. Although the waste cutting operation for cutting off the unnecessary portion including the chip Z is not performed, the single plate 1 that flows into the passage a of the upper effective single plate as illustrated in FIG. When there is a chip Z having a width sufficient for excision, the control mechanism 13 tentatively determines that the single plate detection mechanism 3 detects the passage of the front and rear ends of the chip Z and transmits a detection signal. In addition, the damper 8 is opened and the scrap cutting operation is controlled by the cutting blade 5. Therefore, the unnecessary portion including the chip Z is cut as scrap S and discharged to the waste discharge path c.
[0044]
In addition, as illustrated in the upper right side of the upper center of FIG. 9, an unnecessary portion of the veneer 1 that flows into the passage a of the upper effective veneer (a part of the notch Z having a width sufficient for cutting in this example). In the case where the unnecessary portion is present at the foremost portion of the veneer 1, it is too late to cut out the unnecessary portion and discharge it to the waste discharge path c. The mechanism 13 does not control the scraping operation to cut off unnecessary portions, and is merely shown in the upper center left side of FIG. 9 (or as illustrated from the upper center left side to the lower center in FIG. 8). Only when there is an unnecessary portion to be excised other than the most distal portion of the veneer 1 that flows into the passage a of the effective veneer, the damper 8 is temporarily opened and the cutting blade 5 is used. It is configured to control the scrap cutting operation.
[0045]
However, as illustrated in the lower center of FIG. 9, an unnecessary portion to be excised at a portion other than the most distal portion of the veneer 1 flowing into the passage a of the upper effective veneer (in this example, sufficient for excision). Even if there is a chipped Z) having a width, if the distance X from the tip of the veneer 1 to the unnecessary part (chip Z) to be cut is relatively short, the scraping operation for cutting off the unnecessary part If this control is performed, a relatively narrow single plate (random single plate) is obtained, and the relatively narrow single plate is caught or clogged in a subsequent drying process or the like. Since there is a risk of causing trouble, the period from when the measurement signal is transmitted from the standard measuring mechanism 9 to when the detection signal on the front end side of the unnecessary portion is transmitted from the single plate detection mechanism 3 satisfies the desired minimum period. Even in cases where there is not, it is preferable to use a control that exceptionally stops the cutting operation of the cutting blade. In addition, when such control is used in combination, as shown in the drawing, a single plate (in this example, a random scale corresponding to a relatively narrow single plate followed by an unnecessary portion (chip Z)) However, there is no practical problem at all.
[0046]
According to the processing apparatus having a control mechanism having a different configuration as described above, it is possible to carry out another single plate processing method according to the present invention. The processing device to be used is not limited to the processing device having the configuration described so far, and various modified examples / design examples, etc., can be given for configurations other than the control mechanism. A description will be made sequentially.
[0047]
First, as a single plate detection mechanism constituting the cutting device, a single plate detector that operates according to the thickness of a single plate as shown in FIGS. Although a plate detection mechanism is preferable, it is not necessarily limited to such a configuration, and illustration is omitted. However, instead of the swing arm and the single plate detector of the example of FIGS. Similar to the standard measuring instrument of the example, even a single plate detection mechanism comprising a single plate detector such as a limit switch or a photoelectric switch that operates in response to the presence or absence of a single plate, or the image sensor In this way, even a single plate detection mechanism including a single single plate detector for discriminating the projection shape of a single plate may be any mechanism that can detect an unnecessary portion of a single plate.
[0048]
Next, the example of FIG. 10 includes a rotary encoder 15 that rotates in accordance with the rotation of the transfer conveyor 2 instead of the standard measuring instruments 9a and 9b of the examples of FIGS. And the width of the single plate 1 passing through the position of the single plate detection mechanism 3 is measured in advance based on the detection signal on the front end side from the single plate detection mechanism 3 and the measurement signal of the rotary encoder 15. It is an example that can indirectly measure that the tip of a single plate that has passed the cutting edge position of the cutting blade reaches a position where it can be measured, and as a standard measuring mechanism, other illustrations are omitted, For example, it is a standard measuring mechanism that is equipped with a standard measuring instrument that discriminates the projected shape of a single plate, such as an image sensor, at the front of the cutting mechanism or at the position facing the upper and lower two-stage effective single plate conveying path. Even so, the veneer that passed the cutting edge position of the cutting blade Tip sufficient that directly or indirectly measure may mechanism that leads to standard length possible position.
[0049]
Further, in the example of FIG. 10, instead of the semi-variable speed type upper transfer conveyor 6 of the example of FIGS. 1 and 2, the process up to the merging point of the transfer paths a and b of the two upper and lower effective single plates. The transport process length of the transport path a of the upper effective veneer is longer than the transport process length of the transport path b of the lower effective veneer by an approximately odd multiple of the standard width of the veneer. The upper transport conveyor 16 is configured to be variable, and the upper effective veneer transport path a is configured, and the lower cut effective veneer transport path b is configured by the cut single plates. This is an example in which the images are sequentially stacked on the lower conveyor 17.
[0050]
More specifically, the upper conveyor 16 is constituted by a pair of front and rear folded conveyors 16a and 16b that are engaged with each other as shown in the figure, and the engaged state of the folded conveyors 16a and 16b is indicated by a solid line. By changing from the state to the state indicated by the dotted line, the transport process length of the transport path a of the upper effective veneer until reaching the confluence of the transport paths a and b of the upper and lower two-stage effective veneer is It is possible to change the conveyance process length so that it is longer than the conveyance process length of the effective veneer conveyance path b by approximately an odd multiple of the regular width of the single sheet. Even if it changes, it is possible to sequentially superimpose the cut single plates on the lower transfer conveyor 17.
[0051]
Incidentally, in the example of FIG. 1 and FIG. 2, for convenience of distinguishing and explaining the function of each member constituting the apparatus, each member is illustrated as being separated, but as shown in the example of FIG. If the upper conveyance conveyor 16 is stretched in the fulcrum shaft 5a of the blade 5 and the lower conveyance conveyor 17 is stretched in the support shaft 8a of the damper 8, the conveyance of the single plate becomes more stable. Preferably, the examples of FIGS. 1 and 2 can be similarly changed. Further, as shown in the example of FIG. 10, if the deposition apparatus 14 is configured with two deposition tables 14 c as necessary, it can be divided into a disordered single plate pile 10 a and a regular single plate pile 10 b. 1 and 2 can be similarly modified.
[0052]
Next, as an opening / closing member that opens and closes the waste discharge path, from the viewpoint of quick response, appropriate opening / closing accuracy, etc., an oscillating damper (hollow wing shape is preferable, as shown in FIGS. 1 and 2, A plurality of plates may be sufficient), but is not necessarily limited to a swinging damper. For example, as shown in the example of FIG. 11, a plate-like or comb-like reciprocating damper 18 is conveyed at the lower stage. Even if the reciprocating damper 18 is arranged to reciprocate back and forth in a timely manner through the operation mechanism 19 such as a fluid cylinder / cam, etc. under the control of the control mechanism 13 in the vicinity of the start end of the conveyor 7c, the excision is also cut off. It is possible to discharge the waste S to the waste discharge path c. In short, any member that can open and close the waste discharge path is sufficient.
[0053]
In the example of FIG. 11, the upper transport conveyor 6 c constituting the upper effective veneer transport path a is provided with a deposition apparatus 14 having two deposition platforms 14 c and a lower effective veneer transport path. The lower transfer conveyor 7c constituting b is connected to a deposition apparatus 14 having a deposition platform 14c, and is divided into a stack of piles 10a of a random plate and a stack of piles 10b of a regular plate. In this example, deposition is performed, but the deposition apparatus connected to the single-plate processing apparatus according to the present invention is not necessarily limited to the semi-manual deposition apparatus described above. It is possible to use various types of automatic deposition equipment, and even for irregularly-sized single plates with uneven widths, for example, the reference of the drop position when dropping automatically is alternated between the front end side and the rear end side. If you switch to It can be deposited on the body-shaped deposition mountains.
[0054]
Next, as a cutting mechanism that constitutes the main part of the cutting device, a pair of upper and lower conveying rollers 4a that also serve as blade receivers as shown in each of the above examples in view of adaptability of high-speed processing, simplicity of structure, and the like. Cutting blade provided with 4b and the blade tip turned in the direction opposite to the traveling direction of the veneer 1 and the blade tip is alternately turnable in one way in the section where the blade tip is in contact with the exit side peripheral surface of each of the transport rollers 4a and 4b 5 and a rotating mechanism 11 having a rotating mechanism 11 for alternately rotating the cutting blade 5 in one way are suitable, but the cutting mechanism is not necessarily limited to the above-described cutting mechanism. It is possible to use various conventionally known continuous cutting type cutting mechanisms with different numbers, and in short, any cutting mechanism having a function of continuously cutting a single plate and separating it up and down is sufficient.
[0055]
For example, a cutting mechanism having a different configuration from the above examples will be described. In the example of FIG. 12, the circular saw-like piercing member 21 having a large number of piercing bodies 21 a on the outer periphery is used as the axis of the rotary shaft 22. It is equipped with multiple sheets at appropriate intervals in the direction, and is pierced and transported in the direction of the arrow shown in the figure at a speed synchronized with the veneer race by an appropriate drive source (not shown) such as an electric motor with a reduction gear or a servo motor. The end portion of the transfer conveyor 2 in which the cutting edge directed in the direction opposite to the traveling direction of the body 20 and the veneer 1 is close to the piercing carrier 20 and below the piercing carrier 20 The cutting blade 25 held by the blade holder 23 and the blade presser 24 and the base end side are pivotally supported by the fulcrum shaft 26a so that at least the single plate 1 can be passed through, Side is a section between dotted line position (standby position) and solid line position A plurality of plate-like upper single plate guide members 26 extending within the interval of the piercing member 21 and a base end side are pivotally supported by a fulcrum shaft 27a, and a tip end side is a dotted line position (standby position). And a solid line position so as to be able to swing between the plurality of plate-like lower single plate guide members 27 extending within the interval of the transfer conveyor 2 and the control of a control mechanism (not shown). The single-plate guide member 26 and the lower single-plate guide member 27 are alternately moved one way, and an operating mechanism 28 such as a fluid cylinder and a cam, and the detachment of the single plate 1 from the piercing body 21a are positioned above the cutting blade 25. 3 shows a cutting mechanism having a comb-shaped peeling member 29 that assists and a free-rolling support roller 30 provided below the roller 3a of the single plate detection mechanism 3.
[0056]
Even with the cutting mechanism having the above-described configuration, the actuation mechanism 28 is based on the detection signal from the single plate detection mechanism 3 on the front and rear ends of the single plate 1 or the measurement signal from the standard measurement mechanism (not shown). Each time the upper veneer guide member 26 and the lower veneer guide member 27 are rotated one way alternately between the dotted line position and the solid line position, unnecessary portions of the veneer 1 are cut as waste S, and a waste discharge path. Since it can be discharged to c, or the single plate 1 can be cut at regular intervals, it can be applied to the configuration of the main part of the cutting device in the single plate processing apparatus according to the present invention. Although not shown in the figure, for example, movable blades are individually provided obliquely above and obliquely below the front of the fixed blade fixed at a predetermined position, and unnecessary portions on the front end side of the single plate are formed by movable blades obliquely below. Unnecessary parts on the rear end side of the veneer are cut separately by a movable blade diagonally above Cutting mechanism and so that construction can be applied like.
[0057]
Incidentally, the example of FIG. 12 is an example in which a so-called replacement blade type cutting blade that is fixedly held by a blade holder and a blade presser is used as a cutting blade. Compared with the case of using, it is advantageous because the maintenance cost can be reduced in general, and the oscillating cutting blade 5 in the example of FIGS. 1 and 2, the example of FIG. 10, the example of FIG. In addition to the case of using a known re-grinding type cutting blade, if necessary, it is held by a blade holder 33 and a blade holder 34 provided so as to be swingable about a fulcrum shaft 31 as illustrated in FIG. It is possible to change the design to replace the replacement blade type cutting blade 35.
[0058]
Further, the projection 23a provided on the lower side of the blade holder 23 shown in the example of FIG. 12 conceals the tip of the damper 8 from the waste discharge path when opened to open the waste discharge path. It is effective because it prevents the trouble that the scrap S is caught on the tip of the damper 8, and it is preferable to provide the same protrusion 32 on the blade holder 33 in the example of FIG. Although not shown in the drawings, in the examples of FIGS. 1 and 2, the example of FIG. 10, and the example of FIG. It is preferable to provide a similar protrusion on the blade support member.
[0059]
It should be noted that the protrusions in each of the above examples need not be continuous, as long as they can conceal the tip of the damper when opened, from the waste discharge path, and may not be suitable depending on the shape of the damper. It can be a few plates.
[0060]
Next, as the transport mechanism that constitutes the transport path of the upper and lower two-stage effective single plate, a transport conveyor of a method that supports and transports a single plate from below as in the above examples is simple, but this method is not necessarily The present invention is not limited to the above-mentioned conveyors, and various conventionally known transport mechanisms such as a sticking conveyor that sticks and transports a single plate from above, or a suction conveyor that sucks and transports a single plate from above, for example, are used. In short, a veneer carried from a cutting device is used as a rear deposition device or the like (a veneer is not necessarily limited to only a deposition process. Any transport mechanism that can be transported to a drying device, a transporting device to the drying device, etc. to be processed may be sufficient.
[0061]
【The invention's effect】
As can be seen from the above, according to the veneer processing method according to the present invention, a cutting device having a single cutting mechanism can be provided and a veneer can be cut continuously. In addition, there is no risk of generating unnecessary shaping waste in the subsequent recumbent process and the like as a result. Even when using a cutting mechanism having a consumable member that does not reduce yield and increases in proportion to the operating state, it is generally sufficient to keep a single cutting mechanism in an operating state. There are various advantages such as a reduction in maintenance costs required for renewal of members. Further, in the execution of the veneer processing method according to the present invention, it is possible to use processing apparatuses having various configurations as described above, but in particular, the examples of FIGS. 1 and 2 and FIG. For example, a processing apparatus provided with a cutting device having a cutting mechanism (partially including the example of FIG. 13) as in the example of FIG. 11 is suitable because it has excellent adaptability for high-speed processing, simplicity of structure, and the like. It is.

In addition to closing the discharge path, be sure to perform a standard cutting once. Even after that, when there is no unnecessary part in the succeeding veneer, when there is an unnecessary part at the most advanced part of the veneer flowing into the passage of the upper effective veneer, and in the lower effective veneer When there is an unnecessary part on the veneer that flows into the passage, the cutting part is cut at a fixed length while the waste discharge path is closed, and the cutting edge of the veneer that flows into the upper effective veneer passage Only when there is an unnecessary part to be excised at a site other than the above, the opening / closing member is tentatively opened via an operating mechanism to open the waste discharge path and to remove the unnecessary part of the veneer. A single-plate processing apparatus comprising a control mechanism for operating the cutting device so as to perform a scraping operation for cutting as follows. A pair of upper and lower transport rollers that also serve as blade receivers, and the blade tip is directed in the direction opposite to the direction of travel of the single plate, and the section where the blade tip contacts each outlet side peripheral surface of the transport roller can be rotated one way alternately. A cutting plate having a cutting blade and a rotating mechanism for alternately rotating the cutting blade in one way, and a single plate detector for detecting an unnecessary portion of the single plate at the front of the cutting mechanism. A single plate detection mechanism that is arranged in a direction orthogonal to the traveling direction of the blade, and that the tip of the single plate that has passed through the cutting edge position of the cutting blade reaches the position where it can be measured directly at an appropriate position. Or a measuring mechanism that measures indirectly, at the rear of the cutting device that continuously cuts the single plate delivered from the veneer lace at the rear of the veneer and separates it up and down Efficient veneer transport mechanism consisting of two stages, upper and lower, to discharge waste between the lower transport mechanism and the cutting device And an opening / closing member that opens and closes the waste discharge path, and an operating mechanism that opens and closes the opening / closing member, and further arrives at the cutting device. Until the width of the plate reaches the width that requires regular cutting, based on the detection signal from the single plate detection mechanism, the opening / closing member is opened via the operation mechanism to open the waste discharge path, and When the width of the incoming veneer reaches the width that requires standard cutting, the operation mechanism is activated based on the measurement signal from the standard measuring mechanism. The opening / closing member is closed to close the waste discharge path, and the cutting operation is always performed once. Further, after that, the detection signal from the single plate detection mechanism and the fixed measurement are performed. Based on the measurement signal from the mechanism. There is no unnecessary part in the case, there is an unnecessary part in the most advanced part of the single plate that flows into the upper effective veneer passage, and there is an unnecessary part in the single plate that flows into the lower effective single plate passage. In the case where it exists, there is an unnecessary part to be excised in a part other than the most advanced part of the veneer that flows into the passage of the upper effective veneer while performing the cutting operation for each standard size while blocking the waste discharge path. Only in the case where it exists, the opening / closing member is temporarily opened through an operating mechanism to open the waste discharge path, and to perform a scraping operation for cutting unnecessary parts of the veneer as scrap. A single plate processing apparatus comprising a control mechanism for operating the cutting device.
