DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for depositing veneer veneers.

[0002]

2. Description of the Related Art A veneer veneer (hereinafter, simply referred to as a veneer) which is transported to a predetermined position in a direction orthogonal to a fiber direction by an appropriate transport means is provided on a stacking table or a stack placed below the predetermined position. When sequentially depositing on the veneer pile existing on the table, the support by the supporting members supporting both ends in the fiber direction of the veneer at the predetermined position is released, and the veneer is simply dropped from the predetermined position. Then, when the support by the support member is released, the difference in friction between the veneer and the left and right support members, and the effect of air resistance on the veneer during the fall, cause An adverse effect that the accuracy becomes unstable or inaccurate occurs.

Accordingly, for example, as disclosed in "Method for Depositing Veneer Veneer Veneer" (Japanese Patent Publication No. 54-42506) and "Veneer Veneer Veneer Deposition Apparatus" (Japanese Utility Model Application Laid-Open No. 57-141947), a specific method is disclosed. An improved method has been developed in which the veneer is forcibly dropped while being bent in an arc shape by the pressing of a pressing member provided to be able to ascend and descend above the central portion in the fiber direction of the veneer at the position. Since the left and right air resistances tend to be balanced by bending in a bow shape, and the friction between the veneer and the pressing member acts to prevent the position of the veneer from shifting, the veneer is freely dropped. It is considerably more effective than the case, and has already achieved a reasonable effect in the deposition process.

[0004]

However, even in the above-mentioned improvement method, the friction between the pressing member and the central portion in the fiber direction of the veneer with the lower part completely open is extremely small. Due to the difference in friction between the plate and the left and right support members, there is a considerable tendency to move (shift) the veneer in the fiber direction, so that the veneer is simply forcibly dropped while bending in a bow shape Alone is not enough to guarantee the stacking posture and the stacking accuracy. More preferably, the center of the veneer in the fiber direction is bent in an arc until the center of the veneer comes into contact with the stacking table or the veneer stack. It is better to surely press the stacking table or the veneer stack, and then to perform the stacking in the order of releasing the support of both ends by the support member, and the implementation in such a mode is already partially useful. However, its implementation had certain limitations.

[0005] That is, for example, another "automatic stacking device for plywood veneers" (Japanese Patent Application Laid-Open No. 52-115071).
"Deposition equipment for veneer veneer gluing machine"
No. 102) and the above-mentioned improvement method are used in combination, and other deposition methods are carried out, such as depositing on the same deposition table with the fiber directions of different types of veneers crossing each other. In the case where it is necessary to provide a relatively large drop between the predetermined position and the deposition table or the veneer pile due to the necessity of intervening members used for It was difficult to implement.

More specifically, in the case where a relatively large drop is provided between a predetermined position and a pile or a pile of veneers, the center of the veneer is supported while supporting both ends in the fiber direction. Or, if it is bent until it comes into contact with the veneer pile, fatal inconvenience that the veneer is damaged is likely to occur, especially in veneered veneers, veneers with poor toughness in the fiber direction, etc. In order to prevent the occurrence of the above-mentioned inconvenience, it is inevitable to implement the above-described improvement method in a form in which the veneer is forcibly dropped while being bent in an arc within a range where the veneer is not damaged. Deterioration of deposition accuracy was inevitable.

[0007]

Reference numeral 13 denotes a flat pressing bar corresponding to a pressing member for pressing the central portion of the veneer 1 in the fiber direction, which is located above the central portion of the veneer 1 in the fiber direction at the start of deposition. As described above, a bumper cylinder 14 for cushioning a collision is provided below a lift base 15 attached to a lower end of a lift rod 16 that moves up and down along a guide 17 fixed to a machine frame (not shown). Based on the control of the control mechanism 21, the central unit in the fiber direction of the veneer 1, which is raised and lowered intermittently in a timely manner by the operation of a pushing drive source 18, which will be described later,

As shown in FIG. 3 (b), the constraining bar 7 is lowered independently in place of raising and lowering the transfer bar 4a to support and restrict both ends of the veneer 1 in the fiber direction. Then, the veneer 1 is forcibly lowered, and then, as illustrated in FIG.
(However, at the time of approaching or immediately after contacting the first veneer only with the deposition table 19), the restraint bar 7 is lifted independently to release the restraint on both sides of the veneer 1 in the fiber direction. At the same time (in the embodiment, slightly later than the release), the pressing bar 13 forcibly presses the central portion of the veneer 1 in the fiber direction downward,
Further, as illustrated in FIG. 3D, while the central portion of the veneer 1 in the fiber direction is pressed by the veneer pile 20 (only the first veneer is the deposition table 19), The deposition is sequentially performed in the order of releasing the support from below both ends in the fiber direction of the plate 1.

If the stacking is performed in such an order, the both sides of the veneer in the fiber direction are supported and restrained from both the upper and lower directions to lower the veneer.・ There is no risk of displacement, and the center of the veneer in the fiber direction is pressed against the stacking table or veneer pile, and then the support on both sides by the support member is released. Even if there is a difference in friction between the veneer and the veneer, there is no risk of the veneer being displaced in the fiber direction. Despite having a relatively large drop with respect to the position, it is unnecessary to excessively bend the central part of the veneer in the fiber direction, so even if the veneered veneer is tough in the fiber direction, Even when targeting inferior veneers, these vulnerable Eliminates the risk that conveniently occurs, conventional problems can be solved all.

FIG. 4 is an explanatory front view of another embodiment of the deposition apparatus according to the present invention, which will be described in more detail below. ,
Detailed description is omitted.

In the drawing, reference numeral 22 denotes a carry-in conveyor located somewhat inside the carry-in conveyor 2 described above, which is driven continuously or intermittently at the left and right simultaneously by a single drive source (not shown). The veneer 1 is provided to carry the veneer 1 to the transfer position in the direction orthogonal to the fiber direction while maintaining the posture set in the previous process. Therefore, in the case of continuous driving, the single-plate detector is of course unnecessary, and even in the case of intermittent driving, only one single-plate detector is sufficient, and the posture of the single-plate is further adjusted. If correction is necessary, an appropriate posture correction mechanism may be separately provided.

Reference numeral 23 denotes a transfer bar located somewhat outside the transfer bar 2 so as to face a transfer conveyor 24 to be described later, and engages with the veneer 1 more smoothly than the belt 24a of the transfer conveyor 24. When the transfer conveyor 24 transfers the veneer 1, it comes into contact with the lower surface on both sides in the fiber direction of the veneer 1.

Reference numeral 24 denotes a transfer conveyor which is a modified example of the transfer means, which includes a pair of left and right belts 24a, a pulley 24b, and a shaft 24c stretched from a transfer position to a predetermined position.
(It may be common for the left and right sides), etc., and it is driven intermittently by an intermittent drive source (not shown) consisting of a servo motor, a motor with clutch & brake, etc. Each time the front end of the veneer 1 reaches the position of the veneer detector 24d, the left and right sides of the veneer are temporarily suspended, and the veneer 1 is moved from the transfer position to the predetermined position in the direction orthogonal to the fiber direction. Transfer.

Reference numeral 25 denotes a pair of left and right channel-like support bars, which have an engagement surface for engaging the veneer 1 more smoothly than the belt 24a of the transfer conveyor 24, and are similar to the support bar 5 described above. The lifting arm 12 is attached to the swinging end of the support arm 6 and is controlled by a control mechanism (not shown) in accordance with the configuration of the control mechanism 21 to obtain the operation of the lifting cylinder 12 and to raise and lower it intermittently in an appropriate time. At the same time, the operation of the opening / closing cylinder 9 is performed, and the opening / closing is performed intermittently for an appropriate period of time. In cooperation with the restraining bar 27 described later, the veneer 1 is once forcibly lowered, and then the support is released.

Reference numeral 27 denotes a pair of right and left semi-circular bar-shaped restraining bars, which are provided below the lifting frame 10 via a working cylinder 28, and are controlled by a control mechanism (not shown). With the operation of 28, the veneer is independently lifted and lowered at appropriate times, and while temporarily restraining both sides of the veneer 1 in the fiber direction, the operation of the lifting and lowering cylinder 12 is obtained, and is lifted and lowered integrally with the support bar 25 at appropriate times. In cooperation with the support bar 25, the veneer 1 is once forcibly lowered, and then the constraint is released.

For example, even with the deposition apparatus configured as described above, single plates can be sequentially deposited in an operation order similar to the operation order illustrated in FIG. 3, and the deposition apparatus illustrated in FIGS. Similar functions and effects can be obtained. Of course, in any of the deposition apparatuses, it is possible to process a plurality of veneers at a time as needed.

As is clear from the above embodiments, in the deposition apparatus according to the present invention, as long as the function is not impaired, the form of the members used may be appropriately changed in design and shown. In addition to the embodiments, there are other embodiments having the same function, and therefore, these will be supplementarily described below.

First, regarding the support member, the form in which the veneer is passively slid like the support bar in each of the above embodiments is the form in which the veneer is actively transported (for example, a conveyor shape). Since the required space (particularly the space in the height direction) is smaller than that of the above, and it is convenient that the whole veneer can be lowered to a lower position, it is convenient to transfer the veneer to a predetermined position. It is preferable to separate them, but the point is that it is sufficient if at least the lower surfaces of both sides in the fiber direction of the veneer in the deposition process can be stably supported. It is also effective to apply a friction reducing treatment such as coating and plating, or to form at least a portion engaged with the veneer with a material having low friction.

Next, with regard to the restraining member, the shape that extends over the entire width in the direction orthogonal to the fiber direction of the veneer, like the restraining bar in each of the above embodiments, is spaced apart from each other. It is preferable because the restraint is more stable than the divided shape, but the point is that the support member is used as a fulcrum by the action of a roller with the support member as a fulcrum, or by the clamping action with the support member. It is sufficient that both sides of the veneer in the fiber direction during the descent process can be stably restrained by the combined use of the action of the roller and the pinching action with the support member (for example, the support arm) that supports the support member. The surface to be engaged with the veneer is subjected to a friction increasing process such as rubber coating or knurling, or at least a portion to be engaged with the veneer is
It is also effective to use a material having high friction.

Next, with respect to the pressing member, the pressing member having a shape extending over the entire width in the direction perpendicular to the fiber direction of the veneer like the pressing bar in each of the above embodiments is spaced apart from each other. It is preferable because the pressing is more stable than the divided shape, but the point is that it is sufficient if the central part of the veneer in the fiber direction can be pressed stably from just before the deposition to the completion of the deposition, if necessary. It is also effective to apply friction increasing treatment such as rubber coating or knurling to the engaging surface that engages with the veneer, or to form at least the portion that engages with the veneer with a material having high friction. It is.

Next, a description will be given of the lifting mechanism, in which, in place of the fluid cylinder, a crank device, a cam device, a winding reciprocating device, or the like is provided as an operating engine. Modification examples in which the shape of the lifting frame is changed can be cited, but the point is that any mechanism capable of integrally raising and lowering the support member and the restraining member is sufficient, and it is not always necessary to perform the raising and lowering operation strictly in the vertical direction.

Next, regarding the opening / closing mechanism, it is convenient to use the fluid cylinder as in the above-described embodiments for the operating engine in view of the space saving and the simplicity of the control system. Thus, opening and closing by rocking is appropriate, but the point is that any mechanism capable of integrally opening and closing the support member and the restraining member is sufficient.

Next, regarding the operation mechanism, it is convenient to use the fluid cylinder as in the above embodiments for the operation engine in view of space saving and simplicity of the control system. Any mechanism can be used as long as the mechanism can be individually raised and lowered.

Next, regarding the pushing mechanism, there is a modified example in which a fluid cylinder / cam device or a reciprocating wrapping device is used as an operating engine instead of the crank device.
Also, as is well known, the uppermost surface of the veneer pile tends to be non-flat as the deposition progresses. Therefore, a buffer member such as a buffer cylinder or a sprung member as in each of the above embodiments is interposed at an appropriate place. Although it is desirable to connect the pressing member elastically and freely, it is possible to eliminate or remarkably reduce the unevenness of the uppermost surface by interposing the floor plate in the veneer pile. It is not essential that a member be interposed, but a mechanism that can move the pressing member up and down is sufficient.

Next, the transfer means will be described in a somewhat supplementary manner. The transfer apparatus illustrated in FIGS. 1 and 2 was first described by the present applicant as "a veneer veneer stacking apparatus" (Japanese Patent Application No. 4-205542).
The transfer device used in the invention proposed in (1), wherein the engaging surface of the transfer bar engaging with the veneer is subjected to the same friction increasing treatment as described above, Or, at least the portion that engages with the veneer is made of a material with high friction,
Further, while performing an engagement increasing process such as projecting a number of small projections that slightly enter the interior of the veneer, the same friction reduction as described above is applied to the engagement surface of the transfer bar that engages the veneer. The veneering treatment, or at least the portion that engages with the veneer, is made of a material with low friction, so that the veneer can be stably transferred. However, it is also possible to change to the following format. .

That is, as proposed in the above-mentioned invention, a lock is provided at the lower end of the transfer bar in the transfer direction so as to protrude below the engaging surface for engaging with the veneer. It is possible to change to a form in which veneer is locked and transferred,
In this case, the engagement surface of the transfer bar is configured to be more smoothly engaged with the veneer than the engagement surface of the transfer bar (and the support bar). When stopping, the action of correcting the position of the veneer can also be achieved, and the correction of the position of the veneer by the carry-in conveyor becomes unnecessary.

In the embodiment shown in FIG. 4, a carry-in conveyor and a transfer conveyor are separately provided to carry out the transfer to the transfer position and the transfer to the predetermined position separately. Can be changed to extend the transfer bar and the transfer conveyor to the previous process, so that the carry-in conveyor can be omitted, and there is a possibility that bending due to the own weight of the central portion of the veneer in the fiber direction may become a hindrance. In such a case, a receiving bar similar to the transfer bar may be added below the center of the transfer path.

[0040]

As is apparent from the above, according to the present invention, when veneers are sequentially deposited on a deposition table or veneer pile having a relatively large drop to a predetermined position, for example, a veneered veneer, Even if the veneer has poor toughness in the fiber direction, the veneer can be deposited with good deposition posture and precision without causing damage to the veneer, contributing to streamlining the veneer deposition process at the plywood factory. It is a great deal to do.
