Description

  The present invention relates to a processing method for a veneer veneer, and more particularly to a processing method for a veneer veneer (hereinafter simply referred to as a veneer) immediately after being cut from a veneer lace.

  When a log is turned by veneer lace, an irregular non-strip-shaped veneer is cut from the outer periphery of the log at the beginning of the turning, and then a strip-like veneer is cut after the middle stage of turning when the log is turned into a substantially cylindrical shape. Because it is made, most of the unnecessary parts are cut from each of the single plates, and if necessary, the strip-like single plate is cut for each predetermined standard width and transferred to the subsequent drying device However, the strip-shaped veneer can be easily inserted into the dryer even after it is strip-shaped or cut into a regular veneer with a specified width. On the other hand, the non-band veneer has poor handling properties such as complicated insertion into the drying device even if most of the unnecessary parts have been removed, and immediately after the veneer lace. This is a factor that hinders the rationalization of veneer processing.

  As an effective means to improve the handleability of the non-band veneer, all unnecessary portions of the non-band veneer are removed, and various adhesives, adhesives such as adhesive tapes, yarn / wires, etc. Using a suitable bonding material consisting of at least one of the above-mentioned bonding materials, etc., by sequentially bonding the single plates from which unnecessary portions have been removed, it is formed into a band-like bonded single plate group or necessary. Depending on the condition, after joining or before joining, the united piece is cut every time the accumulated width of the joined single plates becomes a predetermined standard width, and formed into a unitary joint standard single plate. If the processing is carried out in a form directly connected (or connected) to the veneer lace, the single plate processing immediately after the veneer lace can be significantly streamlined.

  However, the proposals of the above-mentioned publications have structural defects due to the characteristics of individual devices arranged for carrying out processing, as will be described later, and none of them has been put into practical use. It is an entity. In detail, veneer lace generally has a function of cutting a veneer at an extremely high speed (usually 90 m to 150 m / min), whereas the veneer lace is placed at a desired cutting position. The cutting mechanism (cutting device) is basically unsuitable for cutting at a high speed, and it is not suitable for veneer lace. If the cutting process is carried out while conveying the veneer at a speed, the following problems are induced.

  That is, as is well known, even if the cutting mechanism has a wide variety of configurations, a cutting blade having an appropriate rigidity is essential to cut a tough single plate, and the holding member is necessarily included. Since the mass of the cutting blade becomes relatively large, when the cutting blade is operated via an operating mechanism including a fluid cylinder, a cam, a crank, etc., for example, a control device such as a fluid control valve that operates the fluid cylinder is used. Naturally, errors occur in the cutting position of the cutting blade due to operating errors or operating errors of drive motors such as a motor with a clutch and brake that operates cams, cranks, etc., servo motors, etc. However, as usual, if the cutting process is carried out while the cutting mechanism is independently provided and the veneer is transported at a general speed of about 30 m / min, the error of the cutting position is at most ± 0. .5mm is enough, actual In contrast, when the cutting mechanism is directly connected to the veneer lace and the cutting process is performed at a speed of 90 to 150 m / min, the error is ± 1.5 to 2.5 mm. For example, an unnecessary part of a single plate is mixed into an effective part, and the formation of a bonded single plate group is hindered or the quality of the bonded single plate group is deteriorated. This can also cause problems that reduce the yield by mixing in unnecessary parts.

  In addition, an increase in the mass of the cutting blade including the holding member adversely affects the responsiveness of the cutting operation, and is naturally a factor that restricts the interval of the cutting operation. For example, from the initial cutting operation, Assuming that the time interval until the next cutting operation is approximately 0.03 seconds, as usual, a cutting mechanism is provided independently, and a veneer is transported at a general speed of 30 m / min. However, if the cutting process is performed, the distance interval from the initial cutting operation to the next cutting operation can be suppressed to about 15 mm, and a practically useful effective portion having a width of about 30 mm ( The cutting process is performed at a speed of 90 m to 150 m / min, while there is sufficient room to obtain an effective single plate) or to cut out an unnecessary portion (defect) having a width of about 20 to 30 mm. In the case, the interval is expanded to 45 mm to 75 mm. Thus, for example, an effective portion having a width of 45 mm to 75 mm cannot be obtained, or, for example, when an unnecessary portion having a width of about 20 to 30 mm is cut off, an effective portion adjacent to the unnecessary portion is cut off excessively. Occurs and, as a result, induces problems that significantly reduce yield.

  Thus, the proposal of the above-mentioned Japanese Patent Laid-Open No. 53-41409 is based on the fact that a single plate joining machine having a built-in cutting mechanism that pauses the conveyance of a single plate every cutting operation (and sorting operation) is directly connected to a veneer race. In addition, the proposal of the above-mentioned Japanese Patent Application Laid-Open No. 55-109608 also adopts a configuration in which a regular cutting device is directly connected to a veneer lace. If it is intended to avoid the induction of the above problems by reducing the turning speed of the veneer lace so as to adapt to the processing capacity of the single plate joining machine or the sizing cutter, the direct connection is possible. Since the processing capacity of the entire line will be drastically reduced, it is extremely impractical.

  In addition, the proposal of Japanese Patent Laid-Open No. 55-9831 discloses that the above-mentioned problems are caused by the unnecessary cutting of the veneer and the cutting of each predetermined dimension by a twin type veneer clipper and a rotary type veneer clipper. However, it is possible to install a plurality of units because a string machine is used to join all the veneers with a width that has been cut away from unnecessary parts to a single veneer of a predetermined size. If the string machine is installed in a number that matches the maximum number of single-width veneers to be delivered according to the proposed configuration, the installation space for the string machine including the bonding veneer stacking device There are significant defects, and in normal times when processing an average amount of veneer, a string machine that is half of the installed cardinal number is inactive. There is a fatal defect that operating efficiency of the processing line, including emissions of worker (operator) is poor, even in light of the recent circumstances that labor saving is desired, very lacking in practicality.

  On the other hand, the proposal of the above-mentioned Japanese Patent Application Laid-Open No. 52-7411 discloses that the entire amount of discontinuous veneers cut at the initial stage of turning of the raw wood is temporarily stored in a tray conveyor and is cut after the middle turning of the raw wood. Utilizing the period during which a continuous single plate formed is separately wound using a winder, discontinuous single plates stored in a tray conveyor are sequentially formed into a continuous bonded single plate group. Because it adopts the configuration, the clipper cutting speed of the clipper that cuts out unnecessary parts of the discontinuous veneer can be significantly reduced compared to the veneer veneer cutting speed, and the above problems can be induced. However, in order to store the entire amount of discontinuous veneers cut from any log without any problem, an extremely long tray conveyor is necessary, and it is very wide behind the veneer race. The actual situation of a plywood factory where it is difficult to establish a If so, this proposal is also still lacking in practicality. For example, if you want to cut a 3mm thick veneer from an almost cylindrical log with a thickness (diameter) of 600mm without cracks, the cumulative width of discontinuous veneers (exclude unnecessary parts) The cumulative width before the measurement is about 4 to 6 m at most. However, even if the log has the same thickness, for example, if there is a crack with a depth of 60 mm penetrating both ends of the log, the cumulative width is However, if it exceeds at least 30 m and, of course, the thickness of the single plate to be cut becomes thinner, the cumulative width will further increase.

  The present invention was developed to eliminate the defects of the known proposals disclosed in the above-mentioned gazettes and the like. Specifically, a single plate cut from the veneer lace is placed behind the veneer lace. The unnecessary part removal device that continuously cuts most of the unnecessary parts and sends only the veneer, at least most of which is the effective part, to the next process, and the belt-like veneer sent from the unnecessary part removal device are specified. A standard cutting device that continuously cuts every width, obtains a seamless single plate and sends it to the next process, and a standard for sequentially depositing the single plate sent from the standard cutting device Unnecessary portions of the front end and the rear end of the single plate stacking device and the non-banded single plate transferred through the regular cutting device are sequentially cut, and the rear end of the preceding single plate and the subsequent single plate The front end is intermittently brought into close contact with each other and bonded with a bonding material. A single plate joining apparatus that cuts each time the accumulated width of the sheet reaches a predetermined standard width, obtains an integrated joining regular single plate, and sends it to the next process, and a joining constant sent from the single plate joining apparatus And a single veneer stacking apparatus for sequentially depositing the veneers, in principle, for non-band veneers cut in the initial turning of raw wood, simply pass through the fixed cutting device. In addition, the above-mentioned single-cut cutting is performed on the strip-shaped single plate formed after the middle turning of the raw wood, in addition to the process of forming the fixed-size single plate sequentially by the single plate joining device and depositing on the joining single plate depositing device. The processing unit sequentially obtains a fixed-size single plate by the apparatus and deposits it on the bonded single-plate stacking device, and on the other hand, at least a part of the transfer mechanism related to the fixed-size cutting device is timely and non-banded. This is an intermittent transfer mechanism that has the function of closely closing the distance between plates, and is limited to a specific time. In other words, the non-banded single plate group that is closely spaced from each other by the intermittent transport mechanism is exceptionally cut according to the band-shaped single plate by the above-mentioned regular cutting device, and is subjected to a desired setting. As a basic proposal, a method for processing a single plate (Claim 1) is characterized in that a non-bonded single plate group having a width is formed, and a process of sequentially depositing the non-bonded single plate group at appropriate locations is performed. Disclose.

  Further, the timing for starting the formation of a non-bonded veneer group exceptionally based on the accumulated width of the non-band veneer that is sequentially sent from the unnecessary part removing device in the initial turning of the raw wood is defined. If the accumulated width of the single plate processing method according to claim 1 and the unbonded single plate group is less than the desired standard width, the leading end portion of the subsequent strip-shaped single plate is additionally supplemented. By this, the processing method (Claim 3) of the single board of Claim 1 or Claim 2 formed by satisfying a desired standard width, and the single-size single board were obtained sequentially from the strip-shaped single board. The remaining veneer and the non-banded veneer that is sent from the unnecessary part removal device at the end of turning of the raw wood are not waiting for the arrival of the non-banded veneer that is cut in the initial turning of the next raw wood, and promptly 4. The device according to claim 1, wherein the device is transferred to a single plate joining apparatus and is not incorporated into a non-joined single plate group. The single plate processing method (Claim 4) and the desired standard width for the unbonded single plate group are aligned with the same standard width as that for the standard single plate. 5. A method for processing a single plate according to claim 1 or claim 2 or claim 3 or claim 4, wherein the non-bonded single plate group is deposited at the same location as the fixed-size single plate; Regardless of the desired standard width for a single plate group, a deposition device for a non-bonded single plate group is provided separately from the standard single plate stacking device, and each of the single plate and non-bonded single plate groups is provided. A single plate processing method (claim 6) according to claim 1 or claim 2, or claim 3 or claim 4, which is separately deposited, is disclosed as an additional proposal.

  In addition, as a standard cutting device that continuously cuts strip-shaped single plates for each specified standard width, together with the cutting function, the cut single plates are alternately discriminated to the upper side and the lower side and sent out. A fixed-size cutting device having a function, and at the rear of the fixed-size cutting device, a two-stage upper and lower transfer mechanism and a single single-size plate that engages with each of the upper and lower two-stage transfer mechanisms. A non-bonded single plate group formed exceptionally only at a specific time and configured to be deposited in the same place as the fixed-size single plate, and transported on the upper side of the two upper and lower stages A single plate joining device and a joining single plate depositing device that are engaged only with the mechanism are provided, and a process for obtaining a unitary joining standard single plate from only a non-band-like single plate that is transferred via an upper transfer mechanism. When performing the process of obtaining the last standard veneer from the portion close to the end of the band-like veneer Assuming that the width of the strip-shaped veneer to be processed in advance is calculated and cutting with a regular cutting device is carried out in a normal order, the remaining veneer that has obtained the regular veneer is transferred to the lower transfer mechanism side. Only in the case of being transferred, as a special case, the last cutting is stopped, and the strip-shaped single plate to be processed is transferred as it is to the single plate joining apparatus. The single plate processing method (claim 7) according to claim 4 or claim 5 is disclosed as an applied proposal.

  In addition, as a standard cutting device that continuously cuts strip-shaped single plates for each specified standard width, together with the cutting function, the cut single plates are alternately discriminated to the upper side and the lower side and sent out. A fixed-size cutting device having a function, and at the rear of the fixed-size cutting device, a two-stage upper and lower transfer mechanism and a single single-size plate that engages with each of the upper and lower two-stage transfer mechanisms. A non-bonded single plate group formed exceptionally only at a specific time and configured to be deposited in the same place as the fixed-size single plate, and transported on the upper side of the two upper and lower stages A single plate joining device and a joining single plate depositing device that are engaged only with the mechanism are provided, and a process for obtaining a unitary joining standard single plate from only a non-band-like single plate that is transferred via an upper transfer mechanism. When performing the process of obtaining the last standard veneer from the portion close to the end of the band-like veneer Assuming that the width of the strip-shaped veneer to be processed in advance is calculated and cutting with a regular cutting device is carried out in a normal order, the remaining veneer that has obtained the regular veneer is transferred to the lower transfer mechanism side. Only in the case of transporting, as a special case, the last cutting is carried out with the position where the specified standard width is calculated backward from the end of the strip-shaped single board as the standard cutting position, and the preceding remaining single board is left as it is. The single plate processing method (Claim 8) according to claim 1 or claim 2 or claim 3 or claim 4 or claim 5 transferred to a plate joining apparatus is disclosed as another application proposal. .

  Furthermore, as a standard cutting device that continuously cuts strip-shaped single plates for each specified standard width, together with the cutting function, the cut single plates are alternately discriminated to the upper side and the lower side and sent out. A fixed-size cutting device having a function, and at the rear of the fixed-size cutting device, a two-stage upper and lower transfer mechanism and a single single-size plate that engages with each of the upper and lower two-stage transfer mechanisms. A non-bonded single plate group formed exceptionally only at a specific time and configured to be deposited in the same place as the fixed-size single plate, and transported on the upper side of the two upper and lower stages A single plate joining device and a joining single plate depositing device that are engaged only with the mechanism are provided, and a process for obtaining a unitary joining standard single plate from only a non-band-like single plate that is transferred via an upper transfer mechanism. When performing the process of obtaining the last standard veneer from the portion close to the end of the band-like veneer Assuming that the width of the strip-shaped veneer to be processed in advance is calculated and cutting with a regular cutting device is carried out in a normal order, the remaining veneer that has obtained the regular veneer is transferred to the lower transfer mechanism side. In this case, the width of the strip-shaped single plate to be processed exceeds the width obtained by adding the specified standard width to twice the minimum width that can be processed by the single-plate joining apparatus. In some cases, as a special case, after temporarily cutting at the temporary cutting position at least the minimum width away from the cutting position immediately before performing the process of obtaining the last single plate, the temporary cutting position The cutting is carried out again at a fixed cutting position separated from the fixed cutting width by a predetermined cutting width, and the temporary single-cut single plate and the remaining single plate are temporarily cut and transferred to a single plate bonding apparatus. A method for processing a single plate according to claim 1 or claim 2 or claim 3 or claim 4 or claim 5. ) And disclosed as yet another application proposals.

  According to the configuration of the first aspect of the present invention, most of the unnecessary portions of the veneer are continuously cut in advance by the unnecessary portion removing device at the rear of the veneer lace, and only the veneer whose at least most portion is the effective portion is the next step. In addition, the strip-shaped single plate is continuously cut for each specified standard width by a standard cutting device to obtain a seamless single plate and sequentially deposited by a single plate stacking device. Therefore, in principle, the accumulated width of non-band single plates to be formed on a fixed-size single plate by the next single plate bonding apparatus is small, and the belt-like single plate is processed. It is sufficient to complete the joining process including the period of time, so that the single plate processing speed of the single plate joining device (single plate joining device disclosed in the above-mentioned JP-A-53-41409 has been disclosed. In the case of a type in which the conveyance of a single plate is paused each time as in a machine, the pause time is included. Total veneer processing speed) can be significantly reduced compared to veneer veneer veneer cutting speed, and various problems caused by cutting position errors and cutting operation intervals are induced. As a matter of course, the intermittent transfer mechanism is limited to a specific time (for example, when an unusually deep crack exists in the log and the accumulated width of the non-banded veneer exceeds the planned limit). The non-banded single plate group closely packed with each other is cut according to the band-shaped single plate by a standard cutting device, and the non-bonded single plate group having a desired fixed width Is formed, and the non-bonded single plate group is sequentially deposited at appropriate locations, so that the functions of the individual devices are effectively and sufficiently utilized without requiring a particularly large installation place, and always delayed. Smooth processing can be performed.

  Thus, the timing for starting the formation of the unbonded veneer group exceptionally may be determined based on various information / signals. However, as in the configuration of claim 2, unnecessary portions are removed at the initial turning of the raw wood. It is convenient to set it based on the accumulated width of the non-band single plates sequentially sent from the apparatus. Further, when the accumulated width of the non-bonded single plate group is less than the desired standard width, as in the configuration of claim 3, by adding and replenishing the leading end portion of the subsequent strip-shaped single plate, the desired fixed width is obtained. If the cutting is performed with a sufficient width, the deposition posture of the non-bonded single plate group is always stabilized, which is convenient. Further, the remaining single plate obtained sequentially from the strip-shaped single plate and the non-band single plate sent from the unnecessary part removing device at the end of turning of the raw wood are as follows: If you do not wait for the arrival of the non-band veneer that will be machined in the initial turning of the raw wood, and transfer it quickly to the veneer joining device and not incorporate into the unbonded veneer group, the total amount of unbonded veneer group Is convenient. Further, as in the configuration of claim 5, the desired standard width for the non-joined single plate group is aligned with the same standard width as that for the standard single plate, and the standard single plate deposition apparatus is used to If the joining single plate group is deposited in the same place as the fixed single plate, there is an advantage that the installation place of the entire direct connection line can be reduced. Further, as in the configuration of the sixth aspect, regardless of the desired standard width for the non-bonded single plate group, a deposition device for the non-bonded single plate group is provided separately from the standard single plate stacking device. If the length of single plate and non-bonded single plate group are accumulated separately, the installation place of the entire direct connection line will be slightly expanded, but for example, the non-bonded single plate group will be reprocessed later with a single plate bonding device There is an advantage that it is easy to separately reprocess only the non-bonded single plate group as needed.

  In addition, as a standard cutting device that continuously cuts strip-shaped single plates for each specified standard width, together with the cutting function, the cut single plates are alternately discriminated to the upper side and the lower side and sent out. A fixed-size cutting device having a function, and at the rear of the fixed-size cutting device, a two-stage upper and lower transfer mechanism and a single single-size plate that engages with each of the upper and lower two-stage transfer mechanisms. A non-bonded single plate group formed exceptionally only at a specific time and configured to be deposited in the same place as the fixed-size single plate, and transported on the upper side of the two upper and lower stages A single plate joining device and a joining single plate depositing device that are engaged only with the mechanism are provided, and a process for obtaining a unitary joining standard single plate from only a non-band-like single plate that is transferred via an upper transfer mechanism. If configured, the entire direct connection line can be stored in a relatively small installation place, and a series of processing can be performed relatively easily. On the other hand, when performing the process of obtaining the last standard veneer from the part close to the end of the belt-like veneer, if you cut with a standard cutting device in the normal order, you will get a standard veneer The remaining veneer may be transferred to the lower transfer mechanism. For example, if the remaining veneer is deposited as it is, there is a problem that the stacking posture of the subsequent single veneer is disturbed, or the following, for example, Waiting for the arrival of non-banded veneers to be machined in the early stages of turning the raw wood, forming the unbonded veneer groups and then depositing them raises the difficulty of increasing the total amount of unbonded veneer groups, respectively. Is done. Even if such a difficulty is allowed, it does not cause a significant problem in practice. However, if necessary, it is possible to avoid the occurrence of the difficulty by adopting the configuration of claims 7 to 9. .

  That is, as described above, in the upper and lower two-stage transfer mechanism provided at the rear of the standard cutting device having a function of alternately discriminating the cut standard plate to the upper stage side and the lower stage side and sending it out. In the case of adopting a configuration including a single plate joining device that is engaged only with the transfer mechanism on the side, each time a process of obtaining the last standard single plate from the portion near the end of the belt-like single plate is performed, Calculating the width of the strip-shaped veneer to be processed in advance, and assuming that cutting with a regular cutting device was carried out in a normal order, the remaining single veneer that obtained the regular veneer was transferred to the lower transfer mechanism side Only in this case, as a special case, as in the configuration of claim 7, the last cutting is stopped and the strip-like single plate to be processed is transferred to the single plate joining apparatus as it is, or claim 8 As shown in Fig. 4, the last cut position is the position where the specified standard width is calculated backward from the end of the belt-like veneer. It is sufficient to transfer the remaining remaining veneer as it is to the veneer joining apparatus, and further, assuming that cutting with a regular cutting device is carried out in a normal order, In the case where the remaining single plate obtained is transferred to the lower transfer mechanism side, the width of the strip-like single plate to be processed is twice the minimum width that can be processed by the single plate bonding apparatus. As a special case, only when the width exceeds the width obtained by adding the specified standard width to the width, as in the configuration of claim 9, at least the minimum width from the cutting position immediately before performing the process for obtaining the last single plate. Once the temporary cutting is performed at the temporary cutting position separated from the temporary cutting position, the cutting is performed again at the fixed cutting position separated from the temporary cutting position by a specified width, and the temporary cutting is performed. Even if the single plate and the remaining non-band single plate are transferred to the single plate joining device, It is possible to avoid the cause of the serial difficulties.

  Schematizing the basic aspect of the present invention, as illustrated in FIG. 1 and FIG. 2, an unnecessary part removing device, a regular cutting device, a regular single plate deposition device, a single unit are disposed behind the veneer race. The plate joining device and the joining single plate depositing device are provided in the above order, and at least a part of the transport mechanism related to the regular cutting device is an intermittent transport mechanism. Thus, as illustrated in FIG. 1, in principle, for the non-band veneer cut in the initial turning of the raw wood, most of the unnecessary parts are cut off by the unnecessary part removing device, and then the above-mentioned standard A strip-shaped veneer that is simply passed through a cutting device, formed into a fixed-sized single veneer by the veneer bonding device, and deposited on the bonded veneer stacking device. As for the above, each of the above-mentioned regular cutting devices is used to sequentially form a regular single plate and deposit it on a regular single plate deposition device. On the other hand, as illustrated in FIG. 2, the non-band-like shape in which the gap is closely packed by the intermittent transfer mechanism only at a specific time in the process of processing the non-band-like veneer in which most of the unnecessary portions are cut off. The single plate group is exceptionally cut according to the strip-shaped single plate by the above-mentioned standard cutting device to form a non-joined single plate group having a desired standard width, and the non-joined single plate group is appropriately Sequential deposition is performed on the place (for example, at the same place as the standard single plate as shown in parentheses, or at the place of a deposition apparatus separately provided as enclosed by a dotted line, for example).

However, the devices and devices constituting a series of direct connection lines are conventionally known except for a control mechanism that performs control unique to the present invention. There is no problem using devices and equipment, and for these known devices and equipment, the description including illustration is simplified for the sake of convenience.

A veneer lace is formed by cutting a single plate 2 having a desired thickness from a raw wood 1 at a high speed. The veneer 2 that has been cut is sent to an unnecessary part removing device B, which will be described later, via a delivery conveyor 6 that continuously runs in the direction of the arrow shown at a speed corresponding to the raw wood turning speed of A.

  B is a pair of upper and lower blade receiving and conveying rolls 7 and 8 that continuously rotate in the direction indicated by the arrow at a speed according to the log turning speed of the veneer race A. The cutting blades 9 that alternately rotate in one direction in the direction of the arrows and the effective portions of the single plate 2 are detected so that the cutting edges 9a are alternately in contact with the outlet side peripheral surfaces of the conveying rolls 6 and 7 (effective portions and unnecessary portions). Is a known unnecessary part removing device having a single plate detection mechanism 10 or the like, and a control mechanism based on a detection signal of the single plate detection mechanism 10. Under the control of G1, the cutting blades 9 are alternately rotated one way in the direction of the arrow shown in the figure, and most of the unnecessary portions 2a of the veneer 2 cut from the veneer lace A are continuously cut off. The direction of the arrow shown in the figure at a speed equivalent to the rotational speed of Via an intermediate conveyor 11 for continuously running (see FIG. 9) at least the majority of the non-band-like veneer 2A and strip as an active portion and a veneer 2B, and sends the fixed-length cutting device C to be described later.

  The function of the unnecessary part removing device B will be described more specifically with reference to FIG. 9 as reference materials. The control mechanism G1 initially controls the cutting blade 9 to wait at a standby position indicated by a dotted line. Thus, all of the single plates 2 that are fed in that do not have an effective portion are all discharged as an unnecessary portion 2a obliquely below the transport roll 8 because the single plate detection mechanism 10 does not emit a detection signal. Eventually, when the single plate 2 in which the unnecessary portion and the effective portion are mixed is fed, the control mechanism G1 cuts the appropriate timing (for example, most of the unnecessary portion on the front end side is cut based on the detection signal of the single plate detection mechanism 10). When the cutting blade 9 is controlled to rotate one way to the position indicated by the solid line at the time of passing the blade tip position), most of the unnecessary portion 2a on the front end side is cut off and discharged obliquely below the transport roll 8. At the same time, the effective part to which some unnecessary parts are attached is transferred to the intermediate conveyor 11. Next, when the effective portion passes the position of the single plate detection mechanism 10, the control mechanism G1 determines that the control mechanism G1 has passed the appropriate timing (for example, the effective portion has passed the position of the cutting edge of the cutting blade) based on the detection signal of the single plate detection mechanism 10. (Soon after), the cutting blade 9 is controlled to rotate one way to the position indicated by the dotted line, so that most of the unnecessary portion 2a on the rear end side is cut out and discharged obliquely below the transport roll 8. Thereafter, by repeating the same control / operation, the non-band-shaped single plate 2A and the band-shaped single plate 2B, at least most of which are effective portions, are sent to the regular cutting device C via the intermediate conveyor 11.

  In addition to the control function of the unnecessary part removing device B, the control mechanism G1 includes a detection signal from the single plate detection mechanism 10 or a single plate detector 12 (if necessary, a single plate detection mechanism 10 is separately provided on the front side of 10) to determine whether the single plate 2 is non-banded or strip-shaped (if the single plate 2 is non-banded, the single plate detection mechanism 10 or single plate detection) The detection signal of the device 12 is intermittently transmitted, and if it is a belt, the detection signal is continuously transmitted), and the control mechanism G2 of the regular cutting device C described later has a function of transmitting a determination signal.

  C is a pair of upper and lower blade receiving conveyor rolls 13 and 14 that rotate continuously in the direction indicated by the arrow at a speed corresponding to the log turning speed of the veneer race A, and is directed in the direction opposite to the veneer conveying direction. The cutting blades 15, which alternately turn in one direction in the direction of the arrows, the non-band single plate 2A, and the single plate 2B formed so that the cutting edge 15a alternately touches the outlet side peripheral surface of the transport rolls 13 and 14 The single plate detector 16 for detecting the passage and the upper and lower sides of the cutting blade 15 are engaged, and at least when the single plates 2A and 2B arrive, the rotational speed of the transport rolls 13 and 14 is increased. It has continuous upper and lower intermediate conveyors 17 and 18 etc. that run continuously in the direction of the arrows shown in the drawing and that temporarily stop running immediately after the arrival of the respective single plates 2A and 2B ceases. It is a well-known standard cutting device, and the control mechanism G And a detection signal of the standard detectors 19 and 20 for detecting that the front end of the strip-like single plate 2B transferred by the intermittent conveyors 17 and 18 has reached the position to be measured and cut, This will be described in detail below by control of the control mechanism G2 based on the determination signal of the limit determination unit 25 for determining that the accumulated width of the non-band single plates 2A collected on the intermittent conveyor 18 has reached the predetermined limit. In this way, there are two types of functions, that is, basic functions and exceptional functions.

  That is, in principle, while the non-band-shaped single plate 2A is sent from the unnecessary portion removing device B, the control mechanism G2 waits for the cutting blade 15 to be indicated by a solid line based on the determination signal of the control mechanism G1. And the upper intermittent conveyor 18 is controlled to run intermittently on the basis of the detection signal of the single plate detector 16, so that the upper intermediate conveyer 18 has a non-banded single plate A2. The distance between each other is closely packed. Next, when the strip-shaped single plate 2B is sent from the unnecessary portion removing device B, the control mechanism G2 rotates the cutting blade 15 one way to the position indicated by the dotted line based on the determination signal of the control mechanism G1. By controlling the upper and lower intermediate conveyors 17 and 18 to run continuously, the non-banded single plate group gathered in the upper intermediate conveyor 18 is a fixed-size single plate deposition apparatus D described later. Are transferred to a single plate joining apparatus E, which will be described later, via the open / close conveyor 22 and the connecting conveyor 26, and the belt-like single plate 2B is transferred to the lower intermediate conveyor 17. When the leading end of the strip-shaped single plate 2B transferred to the lower intermediate conveyor 17 reaches the position of the standard detector 19, the control mechanism G2 uses the detection signal of the standard detector 19 to By controlling so that 15 is rotated one way to the position indicated by the solid line, a seamless single plate 2C having a predetermined standard width W is formed (see FIG. 10) and delivered to the opening and closing conveyor 21 described later. At the same time, the remaining strip-shaped single plate 2B is transferred to the intermittent conveyor 18 in the upper stage. Further, when the leading end of the strip-shaped single plate 2B transferred to the upper intermediate conveyor 18 reaches the position of the standard detector 20, the control mechanism G2 cuts based on the detection signal of the standard detector 20. By controlling the blade 15 to rotate one way to the position indicated by the dotted line, a single-sized single plate 2C is formed and delivered to the opening and closing conveyor 22 described later, and the remaining strip-shaped single plate 2B It is transferred to the intermittent conveyor 17. Thereafter, by repeating the same control and operation, the single-sized single plate 2C is sequentially formed and delivered alternately to the open / close conveyors 21 and 22.

  On the other hand, exceptionally, when the leading end of the non-banded single plate group gathered on the upper intermediate conveyor 18 reaches the position of the limit determiner 25, it is based on the determination signal of the limit determiner 25. The control mechanism G2 controls the cutting blade 15 to rotate one way to the position indicated by the dotted line, to continuously run the intermittent conveyor 18 in the upper stage, and to intermittently run the intermittent conveyor 17 in the lower stage. Thus, the preceding single plate group whose accumulated width has reached the scheduled limit is immediately transferred to the single plate joining apparatus E described later via the open / close conveyor 22 and the connecting conveyor 26, and the subsequent non-band single plate 2A. Are transferred to the intermediate conveyor 17 at the lower stage, and are similarly packed close to each other. Of course, when the cutting blade 15 rotates in one way, if there is a non-band single plate 2A that has just passed through the position of the blade edge 15a (actually many), it is cut and separated into the first half and the second half, The first half is incorporated in the preceding single plate group, and the second half is incorporated in the following single plate group. Then, if the non-strip-shaped single plate 2A is followed only by a small amount, and then the strip-shaped single plate 2B is fed in, then a small amount of non-strip-shaped single plate collected on the lower intermediate conveyor 17 At the rear of the group, the tip portion of the strip-shaped single plate 2B is added and supplemented. When the tip of the non-band single plate group eventually reaches the position of the standard detector 19, the detection signal of the standard detector 19 is displayed. Based on this, the control mechanism G2 rotates the cutting blade 15 one way to the position indicated by the solid line, and continuously runs the lower row conveyor 17 and the upper row conveyor 18 based on the determination signal of the control mechanism G1. By controlling in this way, a non-bonded veneer group 2D having a cumulative width equal to the fixed width W for the fixed veneer is formed in the lower intermittent conveyer 17 (see FIG. 11). The belt-shaped veneer 2B that follows is delivered to the upper stage Is forwarded to conveyer 18, thereafter, similarly to the foregoing description of the principle control and operation, it is sequentially Blank veneer 2C is formed, is delivered alternately to open and close the conveyor 21, 22.

  Also, if the non-banded single plate 2A is followed by a relatively large amount, the tip of the non-banded single plate group gathered in the lower intermediate conveyor 17 reaches the position of the standard detector 19. Then, based on the detection signal of the standard detector 19, the control mechanism G2 rotates the cutting blade 15 one way to the position indicated by the solid line, continuously runs the intermittent conveyor 17 in the lower stage, and the upper stage. By controlling the intermittent conveyor 18 to run intermittently, a non-joined single plate group 2D having the same accumulated width as the fixed width W for the fixed single plate is formed in the lower intermediate conveyer 17. Then, the non-banded single plate 2A that follows is transferred to the intermittent conveyor 18 at the upper stage, and the interval between them is also closely packed. Of course, even in this case, when the cutting blade rotates in one way, if there is a non-banded single plate passing through the position of the blade edge, it is also cut and separated into the first half and the second half. The part is incorporated in the preceding non-joined single plate group, and the latter part is incorporated in the subsequent non-joined single plate group. Hereinafter, similarly, a non-bonded single plate group is formed, or after a strip-shaped single plate is added and supplemented to the rear of the non-band single plate group, a regular single plate is sequentially formed, Delivered alternately to each open / close conveyor.

  D is a pair of open / close conveyors 21 and 22 that travel in the direction of the arrows in the drawing in conjunction with the operation of the intermittent conveyors 17 and 18, and stacking platforms 23 and 24 that move up and down to maintain a substantially constant stacking height. It is a known fixed-size veneer stacking apparatus having a fixed-length veneer 2C (and a non-bonded veneer group 2D) fed via the intermittent conveyors 17 and 18, such as a fixed veneer Each time the opening and closing conveyors 21 and 22 are opened and closed in the left-right direction of the veneer conveying direction each time the leading end is detected by the detector, the fixed veneer 2C (and the unbonded veneer group 2D) Are sequentially deposited on each of the deposition tables 23 and 24. If necessary, when opening and closing each opening and closing conveyor, the traveling of each opening and closing conveyor is stopped, and further, although not shown in the drawings, a single plate or the like above the opening and closing conveyor It is set as the structure provided with a pressing member which can raise and lower, which promotes fall of the.

  E is a well-known single plate joining apparatus previously proposed by the present applicant in “Method and apparatus for joining veneer single plates” (Japanese Patent Laid-Open No. 2003-291106). The front conveyor 27 that travels intermittently in the direction of the arrows shown in the figure at a relatively low speed that can correct defects such as overlapping of the single plates, and the circumferential groove 28a in which the opening / closing selector 31 described later can intervene. There are a plurality of strips, an anvil roll 28 that rotates intermittently in the direction of the arrow in the direction shown by the traveling speed of the front conveyor 27, a single plate detection mechanism 29 that detects an effective portion of the single plate 2A, and a single plate 2A has a cutting blade 30 for cutting the boundary between the effective portion and the unnecessary portion, a reciprocating scrap removing rod 31 for facilitating the dropping of the unnecessary portion 2a on the front end side, and the tip is a groove of the anvil roll. 28a, the veneer 2A It comprises a sorting opening / closing body 30 and a pair of upper and lower sandwiching conveyors 33, 34, etc., which are provided so as to be able to rotate one way alternately in the direction of the arrow so as to switch the passage between the effective part and the unnecessary part. The unnecessary portion 2a of the veneer 2A fed through the connecting conveyor 26 located at the rear of the opening / closing conveyor 22 of the plate stacking apparatus D is cut out, and the joining edge of the veneer 2A is closely aligned and sandwiched. The joining material T is fed by feeding a desired amount of the joining material T such as a rehumidifying joining tape from the forming and transporting mechanism E1 to be transported and the joining material reel TR, and at the same time when the adhesion promoting member 37 to be described later is pressed. A joining material feeding roll 35 for promoting the separation of the material, a guide member 36 for guiding the joining material T to the lower side of the adhesion promoting member 37, a heating function for heating the joining material T as necessary, and a separating function for dividing the joining material T. As well as A bonding edge of a single plate 2A formed by a pair of upper and lower adhesive promotion members 37, etc., provided so as to be movable up and down in the direction indicated by the arrows, and sandwiched and conveyed by a pair of upper and lower sandwiching conveyors 33 and 34 A bonding mechanism E2 for bonding them together with a bonding material T, a moving member 38 such as a ball screw for moving the bonding mechanism E2 back and forth in the direction of the arrow in the figure, and the like of each device of the forming and conveying mechanism E1 and the bonding mechanism E2. With the control of the control mechanism G3 that controls the operation, an adhesion promoting area (predetermined length L) that is appropriately separated by a distance X from the edge approach position U (substantially the cutting position of the cutting blade) of the forming and conveying mechanism E1. Within the unbonded joint edge located in the area indicated by the lines Z1 to Z2, it is always located on the most downstream side in the transport direction (whether the single plate is transported or stopped). Connect to the position of the unbonded joint edge. And a moving mechanism E3 that moves the joining mechanism E2 so as to adjust the position of the adhesion promoting member 37, and cuts off the unnecessary portion 2a of the single plate 2A fed through the connecting conveyor 26 so that the joining edge is formed. By joining closely together and bonding edges to each other with the bonding material T, a bonding standard single plate 2E is formed (see FIG. 12). When there is no unbonded joining edge in the adhesion promoting area, the joining position of the joining mechanism E2 (substantially the central portion of the adhesion promoting member 37) is set to the start position (line Z1) of the adhesion promoting area. The position is controlled preferentially to the arrival of the unbonded joint edge.

  However, the control mechanism G3 has a cumulative width of the non-band single plate 2A from which the unnecessary portion 2a is cut in addition to the control for operating the devices such as the forming and conveying mechanism E1, the joining mechanism E2, and the moving mechanism E3 as usual. Is a predetermined width (it is convenient for post-processing if it is the same as the width W for a single plate), the cutting blade 30 is temporarily operated to The control for cutting the corresponding position at a fixed length and the control for stopping the adhesion by the bonding material T are performed together with the edge that has been cut at a fixed length. The connecting conveyor 26 is long enough to accommodate the scheduled non-band single plate group, and when the non-band single plate group is received from the open / close conveyor 22, the running speed of the open / close conveyor 22 is adjusted. When traveling continuously at a similar speed and transferring a non-band-shaped single plate group to the front conveyor 27 of the single-plate joining apparatus E, it is intermittent with a speed corresponding to the traveling speed of the front conveyor 27. It is desirable to control the vehicle so that it travels quickly.

  F is a known joining single plate deposition apparatus having an opening / closing conveyor 39 that travels in the direction of the arrow in the drawing in conjunction with the operation of the sandwiching conveyors 33, 34, a deposition platform 40 that moves up and down to maintain a generally constant deposition height, and the like. In this case, each time the joining standard veneer 2E delivered from the sandwiching conveyors 33 and 34 reaches a predetermined position (for example, a position where the front end of the joining standard single plate is detected by the detector), the open / close conveyor 39 is simply moved. By opening and closing in the left-right direction of the plate conveying direction, the joining standard single plates 2E are sequentially deposited on the deposition table 40. If necessary, when opening and closing the opening / closing conveyor, the opening / closing conveyor is configured to stop running.Although not shown in the drawing, the bonded standard plate is dropped above the opening / closing conveyor. It is set as the structure provided with the pressing member which can be raised / lowered to promote.

  The veneer processing method according to the present invention is carried out using a series of directly connected lines as described above, for example. In principle, the non-band veneer 2A cut in the initial turning of the log 1 , After removing most of the unnecessary part 2a by the unnecessary part removing device B, simply passing the fixed cutting device C (and the fixed single plate depositing device D) and sequentially joining and fixing by the single plate joining device E. For the strip-shaped single plate 2B that is formed on the scale single plate 2E and is deposited on the bonded single plate deposition apparatus F, and for the strip-shaped single plate 2B that is cut after the turning of the raw wood 1, The process which forms in the board 2C and deposits on the fixed-size single board deposition apparatus D is performed, respectively. On the other hand, in the process of transferring the non-band-shaped single plate 2A from which most of the unnecessary portion 2a has been removed to the single-plate joining apparatus E, for example, when the accumulated width of the non-band-shaped single plate 2A exceeds a predetermined limit, For a specific time only, the non-banded single plate group closely packed with the gap conveyor 17 (and 18) is in conformity with the band-shaped single plate 2B by the regular cutting device C. Is cut to form a non-bonded single plate group 2D having a desired fixed width, and the unbonded single plate group 2D is sequentially deposited on the fixed single plate deposition apparatus D. Without requiring a vast installation space, the functions of individual devices can be used effectively and sufficiently, and smooth processing can always be performed without delay.

  In addition, in the final stage of sequentially forming a fixed-size veneer from a strip-like veneer, there is a very high probability that a veneer that does not satisfy the specified width will remain, and there are defects near the axis of the raw wood, for example. When it is excised as an unnecessary part by the unnecessary part removing device, a non-banded veneer veneer may be sent out following the band-like veneer. Thus, with respect to the remaining veneer that has been obtained from the belt-like veneer in order, and the non-band veneer that is sent from the unnecessary part removing device at the end of turning the raw wood, Awaiting the arrival of the non-strip-shaped veneer that will be machined in the initial stage, in addition to the processing form that incorporates into the unbonded veneer group, the arrival of the non-strip-shaped veneer that will be machined in the initial turning of the next raw wood Without waiting, it is possible to adopt a processing form that is promptly transferred to the single plate joining apparatus and not incorporated into the non-bonded single plate group. According to the latter processing form, the total amount of the non-joined single plate group is It is convenient because it reduces, but as in the previous embodiment, the upper and lower two stages provided at the rear of the regular cutting device having the function of alternately discriminating the cut regular plates to the upper stage and the lower stage In the case of adopting a structure provided with a single plate joining device by engaging only with the upper transfer mechanism, When veneer or the like of the residual in the transport mechanism of the stage flows, wherein it is impossible to take conveniently processing the form (the latter process embodiment).

  Therefore, among the upper and lower two-stage transfer mechanism provided at the rear of the fixed-size cutting device that has the function of alternately discriminating the cut single plate to the upper stage side and the lower stage side, only the upper stage transfer mechanism In the case of adopting a configuration including a single plate joining device by engaging with the belt, when performing the process of obtaining the last standard single plate from the portion close to the end of the belt-like single plate, the belt shape to be processed in advance every time (E.g., calculating the width of the strip-shaped single plate to be processed based on the detection signal of the single plate detection mechanism 10 or the single plate detector 12 and the conveyance speed of the single plate) Assuming that cutting with a standard cutting device is carried out in a normal order, only when the remaining single plate obtained as a standard single plate is transferred to the lower transfer mechanism side, As a special example, as illustrated in FIG. 13, the last cutting is stopped and the strip-shaped single plate 2B to be processed is left as it is. It is transferred to the single plate joining apparatus E and joined to the preceding single plate group to form the fixed fixed single plate 2E, or, as illustrated in FIG. 14, the specified fixed width from the end of the strip-shaped single plate 2B It is sufficient to carry out the final cutting with the position where W is calculated backward as the fixed cutting position, and to transfer the preceding remaining single plate 2A to the single plate joining apparatus E as it is. Assuming that the cutting with the scale cutting device is carried out, the remaining single plate obtained as a standard single plate is transferred to the lower transfer mechanism side, and the width of the strip-shaped single plate to be processed is As a special example, as shown in FIG. 15, the last standard single unit is used only when exceeding the width obtained by adding the prescribed standard width to twice the minimum width that can be processed by the single plate joining apparatus. At least the minimum width that can be processed by the single-plate joining apparatus E from the cutting position immediately before the processing for obtaining the plate is performed. After the temporary cutting at the cutting position, the preceding non-striped single plate that is cut temporarily at the cutting position that is separated from the temporary cutting position by the specified cutting width W and then cut temporarily. 2A and the remaining non-band single plate 2A may be transferred to the single plate bonding apparatus E. However, in the example of FIG. 14, it is necessary to return the cutting blade 15 of the regular cutting device D to the initial standby position (see FIG. 5) after finishing the processing of the strip-shaped single plate 2 </ b> B.

  Moreover, in the said Example, the limit judgment device was provided in the middle of the intermediate conveyor of the upper stage, and the timing which starts the formation of an unjoined single board group exceptionally was based on the accumulation width of a non-band-like single board. In addition to this, for example, a veneer operator may send a determination signal based on visual information. Any configuration that can implement a processing method for forming a non-bonded single plate group having a constant width is sufficient.

  Further, in the above embodiment, when the accumulated width of the non-bonded single plate group is less than the desired standard width, the leading end portion of the subsequent strip-shaped single plate is added and replenished to obtain the desired standard width. Although it is configured to stabilize the deposition posture of the unbonded single plate group (and the fixed-size single plate) by satisfying and cutting, other, for example, the accumulated width of the non-bonded single plate group is set to a desired fixed-width Even if it is less than that, it can be deposited as it is. In particular, although not shown in the figure, a deposition device for a non-bonded single plate group is provided separately from a fixed-size single plate deposition device, and a non-bonded single plate group When depositing separately and later using a single plate bonding device, there is no practical problem even if the deposition posture is somewhat unstable. When the deposition device is provided separately from the standard single plate deposition device, the desired standard width is not necessarily used for the standard single plate. It is not necessary to align the same dimensions as the constant standard dimension width.

  In addition, the individual devices used for a series of direct connection lines are not limited to the types and forms of the above-described embodiments, and devices of different types and forms that are conventionally known can be used. Although it has already been described that the design may be changed as appropriate, specific examples will be given, and these modifications will be briefly described. First, the unnecessary portion removing device and the standard cutting device will be described in the above embodiment. Although not shown in the figure as an apparatus of a type similar to the type, for example, as disclosed in “Differential transfer device in a single-plate transverse stripper” (Japanese Patent Laid-Open No. 55-5867), A twin-type veneer clipper configured such that the movable blade is capable of running cut against a single fixed blade, or a cutting edge as disclosed in, for example, “Single-plate cutting device” (Japanese Patent Laid-Open No. 2-143801) The direction of travel of the veneer In the front of the fixed blade facing in the opposite direction, it is provided with a puncture conveyance body having a number of piercing bodies connected in a circumferential direction in a double row, and is interposed between the rows of piercing bodies to fix a single plate Examples of the cutting device include a single plate guide member that alternately guides the blade to one surface side and the other surface side, and any of them can perform a discriminating action together with a cutting action.

  On the other hand, as a form in which the cutting function and the discriminating function are separated, there is a form as disclosed in "Veneer single plate straightening cutting and dispensing apparatus" (Japanese Patent Laid-Open No. 59-9002). That is, for example, in the modified example of FIG. 16, the unnecessary portion removing device Ba continuously moves in the direction of the arrow shown in the drawing at a speed corresponding to the traveling speed of the delivery conveyor 6 connected to the veneer lace (not shown). An anvil roll 41 that rotates, an appropriate number of cutting blades 42 (in the example, two), and a blade roll 43 that rotates intermittently in the direction of the arrow in the figure at a speed similar to the rotational speed of the anvil roll 41. The cutting mechanism and the support conveyor 44 and the stab conveyor 45 that continuously travel in the direction of the arrow at a speed according to the rotational speed of the anvil roll 41, between the position indicated by the solid line and the position indicated by the dotted line Are formed by separating members 46 and the like that are alternately rotatable in one way, and based on the detection signal of the single plate detection mechanism 10, the cutter roll 43 is intermittently rotated at a suitable time, Board 2 While cutting most of the unnecessary parts, the unnecessary parts and the effective parts of the cut veneer 2 are once stuck by the sticking conveyor 45 by sandwiching the support conveyor 44 and the sticking conveyor 45, and then the detection signal The unnecessary part 2a of the front end and the rear end is discharged obliquely below the staking conveyor 45 by the one-way rotation of the peeling member 46 based on the above, and the non-band single plate 2A and the belt-like single plate 2B, most of which are effective portions, Is sent to the intermediate conveyor 11.

  Further, the standard cutting device Ca includes an anvil roll 41 that continuously rotates in the direction of the arrow in the figure at a speed equivalent to the traveling speed of the intermediate conveyor 11 (the log turning speed of the veneer lace). Two cutting blades 42, and the cutting mechanism is rotated by a cutter roll 43 or the like that rotates intermittently in the direction of the arrow with a speed corresponding to the rotational speed of the anvil roll 41, and the rotational speed of the anvil roll 41. The support member 47 and the piercing conveyor 48 that continuously run in the direction of the arrow shown in the figure with a speed similar to the above, a peeling member provided with a position indicated by a solid line and a position indicated by a dotted line that can be rotated one way alternately. The discriminating mechanism is constituted by 49, 50, etc., and in principle, while the non-band single plate 2A is sent out from the unnecessary portion removing device Ba, it is based on the discrimination signal of the control mechanism (not shown). , The material roll 43 and the peeling members 49 and 50 are put on standby at the positions indicated by the solid lines, and are inserted into the upper intermittent conveyor 53 that runs intermittently in the direction indicated by the arrow on the basis of the detection signal of the single plate detector 16. By transferring the non-band-shaped single plate 2A stuck by the conveyor 48, the gap between the non-band-shaped single plates A2 is closely packed in the intermittent conveyor 53 at the upper stage, and then the unnecessary portion removing device Ba When the belt-like single plate 2B is sent from the non-band single plate group gathered in the intermittent conveyor 53 on the upper stage based on the determination signal of the control mechanism (not shown) via the connecting conveyor 26. Are sent to a single plate joining device (not shown), and the blade roll 43 is intermittently rotated on the basis of the discrimination signal and the detection signal of the single plate detector 16 to thereby remove the belt-like single plate 2B. Cut at regular widths, and turn the stripping members 49 and 50 alternately one way to the position indicated by the dotted line, to the lower intermediate conveyor 51 and the intermediate intermediate conveyor 52, to the lower intermediate conveyor 52 It is configured to transfer 2C alternately.

  On the other hand, exceptionally, when the leading end of the non-banded single plate group gathered on the intermediate conveyor 53 at the upper stage reaches the position of the limit determiner 25, it is based on the determination signal of the limit determiner 25. The control mechanism (not shown) rotates the peeling member 49 one way to the position indicated by the dotted line and causes the lower intermediate conveyor 51 to run intermittently each time so that the lower intermediate conveyor 51 is non-banded. The intervals between the single plates A2 are closely packed. If the accumulated width of the non-band-like single plate A2 to be transferred to the lower intermittent conveyor 51 reaches the desired standard width (the same as the standard width for the single standard plate), the cutter roll 43 in advance. Is intermittently rotated, and if there is a non-banded single plate 2A that has just passed through the position of the cutting blade 42, the accumulated width can be obtained for a standard single plate by cutting and separating the first half and the second half. After forming the non-bonded single plate group 2D that is the same as the standard width W, and after the cut first half portion has passed the position of the peeling member 49, the peeling member 49 is returned to the position indicated by the solid line, The separation member 50 is rotated one way to the position indicated by the dotted line, and the intermediate conveyor 52 is moved intermittently each time so that the interval between the non-band single plates A2 is close to each other in the intermediate conveyor 52. The cumulative width of non-band veneer is assumed to be When the desired standard width is not reached, as in the previous embodiment, the strip-shaped single plate group is moved to the rear of a small amount of the non-band-shaped single plate group gathered in any of the intermittent conveyors 51 and 52. Cutting with the blade roll 43 is performed so as to supplement the tip portion of the plate 2B, and thereafter, the single-sized single plate 2C is sequentially formed in the same manner as described in the previous basic control / operation. The intermediate conveyor 51 and the intermediate conveyor 52 are alternately transferred.
