Description

  The present invention relates to a deposition processing method and a deposition processing apparatus for a standard veneer single plate group.

  Conventionally, among veneer veneers cut from veneer lace, a large number of veneer veneers (hereinafter simply referred to as narrow veneers) whose width in the direction perpendicular to the fiber direction does not satisfy a predetermined standard width. When sequentially processing, in order to improve the handleability in the subsequent drying process, etc., using an appropriate single plate processing apparatus, the unnecessary portions before and after each small single plate are cut off, A set of standard veneer single plates having a desired standard width by cutting each desired standard width and cutting each desired standard width into a pseudo-wide standard plate shape. Hereinafter, the deposition processing apparatus as disclosed in, for example, Patent Document 1 and Patent Document 2, for example, a place where the regular single plate group is deposited in a direction orthogonal to the fiber direction. The transport mechanism that transports to the top of the machine and the falling single plate group at a constant height at all times In order to stop, whenever the stacking table that can be moved up and down at the deposition site and the single plate group reach the upper part of the stacking site, the engagement between the transport mechanism and the single plate group is released, The processing form which deposits a fixed-size single board group sequentially using the deposition processing apparatus provided with the engagement cancellation | release mechanism which drops a fixed-size single board group toward is taken.

  As a problem in adopting such a deposition processing form, the deposition processing proceeds correspondingly, and the deposition height of the sedimentary mountain of the standard single plate group becomes high enough that the deposition mountain can be elastically deformed. In this case, when the width of the narrow single plate located at the forefront or the rearmost end of the single plate transport direction is relatively narrow among the narrow single plates constituting the group of falling single plates, the small width at the time of dropping Due to the vibration of the veneer and the repulsion of the piles, the narrow single plate with the narrow width tends to fall out of the normal pile position and fall down downwards. Since the surface becomes non-flat (both ends are lowered obliquely downward), the probability of further falling tends to increase from the next time, and as a result, the desired neat deposition cannot be performed to the end. It is.

  Therefore, as disclosed in Patent Document 3, the present applicant tentatively provisionally receives a falling single plate group every arbitrary number of units before depositing the single plate group on the pile. In addition, by adopting a processing mode in which the provisionally received medium units are sequentially deposited, a technique for suppressing the occurrence of the above-described problems has been proposed, and corresponding results have been achieved.

Japanese Patent Publication No. 50-111143 No. 2-25602 Japanese Patent Publication No.5-110101

  However, the technique disclosed in the above-mentioned Patent Document 3 is based on the fact that the single plate group once drops to a predetermined deposition position, and then the bottom of the pile is caused by vibration of the small single plate, repulsion of the pile, etc. Since it was a problem to prevent the crash to the side (upper side or lower side of the veneer conveyance direction), the width of the narrow veneer located at the forefront or the end of the standard veneer group When a phenomenon occurs in which the narrow single plate having a relatively small width is abnormally floated in the course of dropping and falls to a position significantly deviating from a predetermined deposition position, the narrow narrow plate There was a defect that made it difficult to prevent the fall of the veneer.

  Furthermore, since the scope of the problem to be solved is limited as described above, it is gradually becoming impossible to cope with the actual situation of the recent single plate processing as described later. In other words, recent single-plate processing tends to be further speeded up mainly for rationalization, but as is well known, the inertia force of a single plate not only fluctuates in proportion to the weight of specific gravity, but also squares the speed. Therefore, if the single plate processing speeds up, the control of the temporary stop position when determining the mutual interval of the narrow single plates constituting the fixed single plate group, or the fixed single plate group It is unavoidable that the control of the drop start position during the drop tends to be rough, and as a result, the drop start position of the narrow veneer located at the forefront or the end of the standard veneer group is already A phenomenon that significantly deviates from a predetermined deposition position sometimes occurs, and if the width of the small single plate is relatively narrow, it is still difficult to suppress the crash.

  The present invention has been developed to repair the defects on the basis of the respective prior arts, and as a practical method, as disclosed in claim 1, a narrow single plate constituting a group of falling single plates is disclosed. Among the plates, at least one of the narrow single plates located at the foremost or rearmost end is at least one of the upper side and the lower side in the veneer conveying direction with respect to a predetermined deposition position. A projecting mechanism for temporarily supporting the end of the protruding part using an appropriately shaped auxiliary support member and releasing the provisional auxiliary support. A method of depositing a fixed-size single plate group, characterized by sequentially depositing the fixed-size single plate group from a plurality of times each time the same is repeatedly carried out.

  And, when carrying out the deposition processing method according to claim 1, as disclosed in claim 2, a processing form in which the number of target single-sheet single plate groups to be processed is one each time, and claim 3 It is proposed that a plurality of processing forms (usually two sheets, but three or more sheets are acceptable) each time can be adopted.

Furthermore, as an apparatus used for carrying out each of the deposition processing methods, as disclosed in claim 4, at least one of the upper side and the lower side in the veneer conveying direction facing a predetermined deposition position on the deposition table. In addition, an auxiliary support member having an appropriate shape that temporarily supports the end of the narrow veneer protruding significantly with respect to a predetermined deposition position is provided so as to be able to advance and retract in the same direction as or in the opposite direction to the veneer conveyance direction. It includes an advancing / retracting operation member for advancing / retreating the auxiliary support member. Under normal conditions, the auxiliary support member is moved forward toward the stacking table, and each time the single plate group from the transport mechanism is dropped a plurality of times. 6. A fixed-size single plate group deposition processing apparatus comprising a control mechanism for controlling the operation of the advance / retreat operation member so as to temporarily retract the auxiliary support member once, and disclosed in claim 5. As you can see, there is only one 5. A fixed single plate group deposition processing apparatus according to claim 4, wherein the single plate group is transportable, and a plurality of fixed single plate groups can be transferred each time as disclosed in claim 6. An apparatus for depositing a regular single plate group as claimed in claim 4 using a transport mechanism .

  According to the deposition processing method according to claim 1, the end portion of the narrow single plate that protrudes significantly from the predetermined deposition position is the auxiliary support member until the fixed single plate group is dropped a plurality of times. Therefore, even if the width of the protruding small single plate is relatively narrow, there is no risk of falling, and even after the auxiliary support by the auxiliary support member is released, For the second and lower standard single plate groups, excluding the upper standard single plate group, the weight of the fixed single plate group (mainly the narrowest single plate located at the forefront or the end) Therefore, even if the width of the protruding small single plate is relatively narrow, the fall is still suppressed, and as a whole, a better deposition process can be performed than in the prior art.

  And, the above-mentioned actions and effects are not only the form of dropping the single plate group one by one each time as in the deposition processing method according to claim 2, but also as the deposition processing method according to claim 3, Even if it is a form in which a plurality of standard single plate groups are dropped each time, it is played without any particular difference.

In addition, the deposition processing apparatus according to the present invention is effective for use in the implementation of each of the deposition processing methods. However, the deposition processing apparatus according to claim 4 has a characteristic that the structure is relatively simple, and claim 5. The deposition processing apparatus according to claim 2 has characteristics adapted to the implementation of the deposition processing method according to claim 2, and the deposition processing apparatus according to claim 6 has characteristics adapted to the implementation of the deposition processing method according to claim 3 .

  Hereinafter, the present invention will be described in further detail based on an example of the embodiment illustrated in the drawings. The transport mechanism, the disengagement mechanism, the deposition platform, and the control device that constitute the deposition processing apparatus are particularly novel forms. It is not necessary, the point is that the transport mechanism has a function of transporting the standard single plate group to the upper side of the deposition place in the direction orthogonal to the fiber direction, and the transport mechanism is fixed each time the standard single plate group reaches the upper position of the deposition place. Disengagement mechanism that has the function of releasing engagement with the single plate group and dropping the single plate group toward the stacking base, and always receiving the falling single plate group at a substantially constant height. As long as it is a control device that controls the stacking platform having a stopping function and each of these mechanisms in the usual manner, various types of conventionally known transport mechanisms and mechanisms including those disclosed in the above-mentioned publications. Since there is no problem using the release mechanism, stacking platform and control unit, redundant explanation For convenience avoided, the respective mechanisms and the like, a simplified illustration and description. Moreover, when the same mechanism / member as the mechanism / member described with reference to the already cited drawings is shown in another figure, the same reference numerals are given and redundant description is omitted.

  FIG. 1 is a schematic plan view of an embodiment of a deposition processing apparatus according to claim 4 of the present invention, and FIG. 2 is a schematic side view of an embodiment of the deposition processing apparatus according to claim 4 of the present invention. is there. In the figure, A is an upper conveyor that constitutes a conveyance mechanism in pairs with a lower conveyor B, which will be described later, for a rotation shaft fixed to a conveyance belt 1a, a pulley 1b, a rotation shaft 1c, and a machine frame (not shown). Provided with bearings (not shown), etc., obtain control of a control device (not shown), and drive the drive intermittently in the direction of the arrows shown in the drawing via drive sources (not shown) such as servo motors, clutch and brake motors, etc. Then, the fixed-size single plate group S carried into the deposition processing apparatus via a carry-in conveyor E, which will be described later, is transported in the direction orthogonal to the fiber direction to above the deposition location.

  B is a lower conveyor which forms a conveyance mechanism in a pair with the upper conveyor A, and includes a conveyance belt 2a, a pulley 2b, a sliding rotary shaft 2c, a belt receiving joint 2d, and a sliding fixed to the machine frame. It is equipped with a bearing for the rotating shaft (not shown), etc., and can be reciprocated in the lateral direction of the veneer conveyance direction. A single plate group S, which is intermittently driven in the direction of the arrow shown in the figure through a drive source (not shown), etc., and is carried into a deposition processing apparatus via a carry-in conveyor E described later, is orthogonal to the fiber direction. In addition to being transported in the direction to above the deposition place, the operation of the disengagement mechanism C which will be described later is obtained, and reciprocally moved sideways in the single plate transport direction to release the support of the standard single plate group S.

  C is a disengagement mechanism, which is a rotation detection unit comprising a working member 3a comprising a fluid cylinder / link device fixed to the machine frame, a rotary encoder coupled to the sliding rotary shaft 2c of the lower conveyor B, etc. Each time the fixed veneer group S transported via the upper conveyor A and the lower conveyor B reaches the upper part of the stacking place, with the control of a control device (not shown). By moving forward from the position indicated by the solid line to the left and right sides from the position indicated by the dotted line, the engagement between the upper conveyor A and the lower conveyor B and the fixed-size veneer group S is released, toward the stacking table 8 described later. The fixed single plate group S is dropped, then the lower conveyor B is moved back to the position indicated by the solid line, and the next fixed single plate group S is put on standby. In addition, when the auxiliary support member 6 (and the advance / retreat operation member 7) described later is provided only on the lower side in the veneer conveyance direction as in the present embodiment, each stability is determined from the stability of the drop start position. It is preferable to control the single-sized single plate group S so that it is dropped with respect to the rear end side. Further, in view of stability in the dropping direction, when moving the lower conveyor B to the left and right sides, It is preferable to control the running of the conveyor A and the lower conveyor B to be stopped for a while.

  Reference numeral D denotes a single plate pressing mechanism, which includes a pressing member 4a including a pressing rod, a pressing operation member 4b including a fluid cylinder / link device fixed to a machine frame, and the like, and controls a control device (not shown). Then, the pressing member 4a is lowered from the position indicated by the solid line to the position indicated by the dotted line so as to be interlocked with the forward movement of the engagement release mechanism C, thereby facilitating the dropping of the fixed single plate group S. The pressing member 4a is raised to a position indicated by a solid line so as to be interlocked with the backward movement of the mating release mechanism C, and the next fixed single plate group S is put on standby. In addition, if a single plate pressing mechanism is attached as in this embodiment, it is beneficial because the posture of the single plate can be stabilized during the fall, but the attachment of the mechanism is not an essential requirement in the present invention. If necessary, it is sufficient.

  E is a carry-in conveyor, which includes a conveyor belt 5a, a pulley 5b fitted to the sliding rotation shaft 2c of the lower conveyor B, and the like, and is the same as the lower conveyor B under the control of a control device (not shown). A plurality of small single plates Sa, which are intermittently driven in the direction of the arrow shown in the figure through a drive source and whose unnecessary portions are cut off, are narrowed to a desired limit or less, and are quasi-wide The fixed single plate group S formed in a plate shape is conveyed in a direction perpendicular to the fiber direction and carried into a deposition processing apparatus according to claim 4 of the present invention.

  6 is an eaves-shaped auxiliary support member having an inverted L-shaped cross section on the end face side in the figure, and is on the lower side in the veneer conveying direction facing a predetermined deposition position set on the upper part of the deposition table 8 to be described later. It is positioned to obtain the operation of the advancing / retreating operation member 7 to be described later, and to advance in the direction opposite to the veneer conveying direction and to move backward in the same direction as the veneer conveying direction. The end of the protruding small single plate Sa (Sa1, Sa2, Sa3 in the partial enlarged operation explanatory diagram described later) is temporarily supported.

  Reference numeral 7 denotes an advancing / retreating member composed of a fluid cylinder / link device or the like fixed to the machine frame. Under the normal condition, the auxiliary support member 6 is controlled by a control mechanism 10 which will be described later. Is moved forward toward the deposition table 8 and the auxiliary support member 6 is moved backward in a direction away from the deposition table 8 as indicated by a dotted line at every required time.

  8 is a stackable table that is provided at the uppermost part with a roll conveyor 8a, and that can be moved up and down. Under the control of a control device (not shown), the table 8 can be moved up and down in the direction of the arrow and dropped. In the case where the stacked single plate group S is always received at a substantially constant height and the piles of the fixed single plate group S falling on the floor plate 9 reach a predetermined height, the roll conveyor 8a is used. And the pile pile 9 is carried out to the side of the machine frame. In addition, if a roll conveyor is attached as in this embodiment, it is convenient to carry out the piles, but for example, it is also possible to carry out the piles by forklift, so the roll conveyor is not an essential requirement. It is enough to attach it.

  10 is a control mechanism for the advancing / retreating operation member 7, which is a control signal of a control device (not shown) that controls the operation of the upper conveyor A, the lower conveyor B, the disengagement mechanism C, the single plate pressing mechanism D, and the like. Based on this, each time the fixed single plate group S is dropped a plurality of times, the operation of the advance / retreat operation member 7 is controlled so as to temporarily retract the auxiliary support member 6 once.

  The deposition processing apparatus according to claim 4 of the present invention is configured, for example, as described above, and hereinafter, the operation mode thereof is also cited with reference to the partially enlarged operation explanatory diagrams illustrated in FIGS. 3 to 5. When the fixed-size single plate group S carried in via the carry-in conveyor E is transported above the deposition place via the upper conveyor A and the lower conveyor B, based on the control of a control device (not shown). The upper conveyor A and the lower conveyor B are stopped for a while and the operation of the disengagement mechanism C is obtained, and the lower conveyor B is moved to the left and right sides. By obtaining the operation of the actuating member 4b and lowering the pressing member 4a, the fixed single plate group S is repeatedly dropped toward the deposition table 8 and sequentially deposited. In this process, Based on the control of the control mechanism 10, In the normal state, the retracting member 7 advances the auxiliary support member 6 closer to the stacking table 8, and the single plate group S is dropped a plurality of times (for example, in the partially enlarged operation explanatory diagrams of FIGS. 3 to 5). The auxiliary support member 6 is temporarily retracted once each time it is performed (5 times in the example).

  Therefore, for example, as illustrated in FIG. 3, the width of the narrow single plate Sa1 located at the forefront of any one of the standard single plate groups S is relatively narrow, and the narrow single plate Sa1 having a narrow width is predetermined. Even if a phenomenon of protruding to a position significantly deviating from the position and dropping occurs, the end portion of the narrow single plate Sa1 having a narrow width is temporarily supported by the auxiliary support member 6, so that during the present time the The fall of the narrow single plate Sa1 with a narrow width is prevented, and further, as illustrated in FIG. 4, it is assumed that the number of drops of the standard single plate group S eventually reaches the specified number, and the auxiliary support member 6 is retracted. However, as long as the narrow single plate Sa1 with a narrow width constitutes the second or lower standard single plate group S excluding the uppermost single plate group S, it is placed on the upper side. Sedimentary mountains by the weight of the regular single plate group S (mainly the narrowest single plate located at the forefront or the end) Since pressed against the will it be subsequently had to fall is suppressed.

  Furthermore, in the course of the deposition process, it is timely (following the backward movement of the auxiliary support member 6 in the illustrated example) so as to always receive the falling single plate group S at a substantially constant height. Although the adjustment (decrease) of the deposition height of the deposition table 8 is also performed (see FIG. 4), as illustrated in FIG. 5, the auxiliary support member 6 is moved forward toward the deposition table 8 under normal conditions. Therefore, the width of the narrow single plate located at the forefront of the standard single plate group is relatively narrow at the time of another deposition processing after the soaking, and the narrow single plate having the narrow width is Even if the phenomenon of falling out of the predetermined stacking position and dropping occurs occurs, the narrow single plate having the narrow width is not more than the second sheet already stacked when the auxiliary support member is retracted. As long as it constitutes a single plate group, the fall will be suppressed. Te good deposition process may be performed.

  In addition, if it is configured to adjust the deposition height of the deposition table together with the backward movement of the auxiliary support member as in the above-described embodiment, an advantage that unnecessary load is not applied to the auxiliary support member and the advance / retreat operation member. However, the adjustment of the stacking height of the stacking table is not necessarily limited to follow the backward movement of the auxiliary support member, and is omitted from illustration, but if necessary, for example, the guide member is arranged on the auxiliary support member. It is possible to prevent the auxiliary support member and the advance / retreat operation member from being damaged by adjusting the stacking height at different times unrelated to the backward movement of the auxiliary support member.

  Although not shown, the auxiliary support member and the advance / retreat operation member in the above embodiment are positioned on the upper side in the veneer conveying direction facing a predetermined deposition position set on the upper part of the deposition table. If it is configured to move forward in the same direction as the veneer conveyance direction and to move backward in the direction opposite to the veneer conveyance direction, and in a normal state, the auxiliary support member is moved closer to the deposition table, When a phenomenon occurs in which the width of the narrow single plate located at the end of the single plate group is relatively narrow, and the narrow single plate having a narrow width protrudes from a predetermined deposition position and falls. It is possible to suppress the fall of the narrow single plate having a narrow width, and further, if the respective members are arranged on both the lower side and the upper side in the veneer conveying direction, the positions on both sides of the upper and lower sides are separated. It is possible to suppress the fall of the narrow single plate that protrudes and falls.

  In any of the configurations described above, the shape of the auxiliary support member is not limited to the shape of the illustrated embodiment, and although not illustrated, the design is appropriately changed to, for example, a flat plate shape or a comb shape. In short, it is sufficient that the end portion of the narrow single plate protruding significantly from the predetermined deposition position is temporarily supported, and there is no particular restriction on the form of the advance / retreat operation member. In short, a member having a function of moving the auxiliary support member back and forth is sufficient. Here, the supplementary support action will be further described. Although the probability is not so high, on the narrow single plate having a small width already temporarily supported by the auxiliary support member, the width is further narrowed. In such a case, the auxiliary support member does not necessarily need to directly support the end of the other narrow single plate, and already has an auxiliary support. It is sufficient to indirectly support the support through the narrow single plate.

  Further, in the embodiment, the single plate group is transported and dropped one by one each time, but as shown in the illustrated embodiment, a plurality of stacked single plate groups are overlapped once. According to the deposition processing apparatus having a transport mechanism configured by using transport equipment (upper conveyor and lower conveyor) that can be transported to a plurality of sheets, each time a plurality of standard single plate groups are transported and dropped as necessary. It is also possible to make it.

  Further, a detailed description will be given of a good correlation between the retraction frequency of the auxiliary support member and the number of drops of the standard single plate group. For example, every time the single plate group is dropped twice, the auxiliary support member is retracted once. By doing so, the probability that the narrow single plate protruding significantly from the predetermined deposition position will be ½ that of the conventional one, and the auxiliary support member is retracted once every time the standard single plate group is dropped three times. If this is done, the simple probability that the same probability will be 1/3 of the conventional one, the number of drops of the standard plate group is increased, and the auxiliary support member is retracted less frequently. However, while it seems to be effective in preventing the fall, the number of drops becomes excessive, and if the height of a single plate group that requires provisional auxiliary support becomes higher than a certain limit, Proper auxiliary support by the support member is disabled, and on the auxiliary support member Since the width veneer is crashed, substantially crash prevention becomes invalid. Therefore, the appropriate number of drops is preferably determined experimentally in consideration of the thickness of the small single plate, the width of the smallest single plate, the number of drops per each time, the safety factor, etc. There is a method in which an integer value obtained by dividing a dimension corresponding to approximately one third of the width of a narrow single plate by the thickness of the small single plate is an upper limit of the number of processed single plates, for example, the width of the smallest single plate Is about 90 mm, and the thickness of the small veneer is 3 mm, (90 mm / 3) ÷ 3 mm = 10. Therefore, it is practical to set the upper limit to about 10 sheets, and processing is performed one by one each time. If there are multiple times of 10 times or less, and 2 times each time, a number of times of 5 times or less is a practical number of drops.

Although not shown, for example, in place of the transport mechanism composed of the upper conveyor A and the lower conveyor B in the illustrated embodiment, an endless stab is formed by locking a large number of piercing bodies on the peripheral surface. A conveying mechanism comprising a puncturing conveyor having a landing conveying belt, a pulley for mounting the piercing conveying belt, a rotating shaft for fitting the pulley, a bearing for the rotating shaft, a drive source for the rotating shaft, and the like. In addition, in place of the single plate pressing mechanism D in the illustrated embodiment, the single plate pressing mechanism serving as a single plate pressing mechanism D has a disengagement mechanism that also serves as a single plate pressing mechanism D. Each time a single plate group that is arranged in the vicinity and is stuck by the sticking conveyance belt reaches the upper part of the deposition place, the disengagement mechanism is operated to fix the fixed plate by the sticking conveyance belt. A mode in which the sticking of the single plate group is released and pressed down to the deposition site is adopted. By deposition apparatus, it can be carried out deposition processing method according to the present invention, if necessary, by appropriately setting the length of the puncturing deposition of barbs wear the conveyor belt, a plurality superposed sheets of constant Although it is possible to carry a stacking process by transporting a single sheet group at a time, although not shown as a transport mechanism, for example, when an adsorption-type transport conveyor is used, or disclosed in, for example, the above-mentioned Patent Document 1 As described above, when a transport mechanism is configured by providing a transport conveyor only on one of the upper and lower sides of a single plate group, since only one sheet can be processed each time, the transport constituting the deposition processing apparatus according to the present invention. It is appropriate to determine the form of the mechanism according to the required number of processed sheets.

Moreover, those Although not shown, if necessary, to the deposition processing apparatus having a transport mechanism of the puncturing deposition conveyor type described At a the paragraph (0046), with At a Sakiki illustrated embodiment The same single plate pressing mechanism can be provided separately. In that case, if necessary, the function of the single plate pressing mechanism is omitted from the disengagement mechanism that also serves as the single plate pressing mechanism. It does not matter if you do it.

  In each of the above-described embodiments, the arrival of the fixed single plate group at the drop start position is determined based on the detection signal of the rotation detector attached to each conveyor. The means for determining the arrival of the plate group at the drop start position is not particularly limited and is not shown. However, for example, a single plate detector composed of a limit switch, a phototube or the like is attached to the appropriate position, and the single plate detector is provided. Based on the detection signal, it may be configured to determine the arrival of the fixed single plate group to the fall start position, or the detection signal of the rotation detector and the detection signal of the single plate detector may be used in combination. Is possible.

  As is apparent from the above, the present invention has a unique configuration for the fall of the narrow single plate on the front and rear end sides of the piles, which occurred when the single plate group is sequentially deposited. In this way, it is possible to perform a better deposition process than in the past. This is a highly effective invention that exerts a ripple effect that further stabilizes the insertion of the plate group.
