Description

[Detailed Description of the Invention] [Object of the Invention] Does this invention constitute plywood? ! This invention relates to a veneer plating system in which several intermediate boards are stacked so that the fiber directions of adjacent veneers are orthogonal to each other. Until now, various types of veneer mechanisms have been proposed and implemented, but
There are problems such as damage to the veneers when transporting and stacking them, the edges of each veneer not being aligned accurately, and poor efficiency, which prevents satisfactory results from being obtained. This is the current situation. This invention was developed with the aim of overcoming these drawbacks of the conventional method. It allows the end faces of each veneer to be accurately aligned without causing damage to the veneers, and is highly efficient in handling thin veneers or fragile veneers. The present invention provides a mechanism suitable for plates as well.

[Structure of the invention]

The stacking shelf consists of a regulating member that abuts one end surface of the veneers that can be raised and lowered, and arm-shaped receivers for placing the veneers that protrude from the regulating member at equal pitches, and the receivers are placed intermittently at each pitch. The embodiment shown in FIG. 1, in which a wicket conveyor is used as a stacking shelf and 3-brie plywood is constructed, will be described. The shelf 1 includes a plurality of rotating wheels 4.5 attached to each of the upper and lower shafts 2 and 3, a regulating member 6 consisting of a plurality of endless strips stretched around each rotating wheel 4.5, and each regulating member. A plurality of arm-shaped receivers 7 protruding from each of the receivers 6 at equal pitches and in the same phase, and a motor, a clutch, etc. that move these receivers 7 intermittently downward (example) or upward one pitch at a time. It is constituted by an intermittent drive mechanism 8 such as a brake, and one end surface of the veneer is brought into contact with the regulating member 6, so that the veneer can be placed on the 8 receiver 7. Note that the contact of one end surface of the veneer by the regulating member 6 is with respect to its regulating surface X.
-X, and the reference plane The front surface x--x is a moving plane that is vertical or slightly inclined (in the embodiment). In addition to the wicket conveyor, the stacking 1I11 has a regulating member formed by a plurality of annular bodies, and a plurality of receiving bodies protruding from the outer peripheral surface of each annular body at equal pitches and in the same phase.
The outer circumferential surface on the side of each annular body may be used as a reference plane, and the annular body may be moved downward or upward by one pitch of the receiving body on the reference plane, in other words, the receiving bodies are placed at equal pitches on the regulating member. Any structure may be used as long as the veneer can be placed on the receiver by protruding, moving the receiver downward or upward one pitch at a time, and bringing one end surface of the veneer into contact with the regulating member.

The insertion conveyor 9 is formed by, for example, extending upper and lower endless bands on front and rear rotating wheels, and conveys the back veneer B in a direction perpendicular to its fibers and feeds it to the receiving body, and the insertion conveyor 10 is, for example, It is formed by a large number of disk-shaped rotating bodies, and conveys the core veneer C coated with adhesive in the direction of its fibers and feeds it to the receiving body. It is formed by stretching an endless belt, and the front veneer F is conveyed in a direction perpendicular to its fibers and fed to a receiver. These insertion conveyors 9, 10, and 11 are arranged so that they can feed the plywood almost all at once in the order in which they are to be constructed, to the adjacent receivers 7 of the stacking shelves 1 that have rotated toward the standard plane XX. be. For example, the insertion conveyor 9 feeds the back veneer B to the receiving body 7-1 located on the uppermost side in the moving direction of the receiving body, and the insertion conveyor 10 feeds the core veneer C to the receiving body 7-2 located next. The insertion conveyor 11 is arranged so as to feed the front veneer F to the receiving body 1-3 located at the lowest position. In the figure, an endless belt conveyor 12
is for feeding the back veneer B to the insertion conveyor 9, the endless belt conveyor 13 is for feeding the front veneer F to the insertion conveyor 11, and the conveyor 1 for many disc-shaped rotating bodies is for feeding the back veneer B to the insertion conveyor 9.
Reference numeral 4 refers to a gluing machine (not shown) that feeds the core and veneer C coated with adhesive on both the front and back surfaces to the insertion conveyor 10. Back veneer B from each insertion conveyor 9, 10, 11
, the core veneer C0 and the front veneer F almost all at once to each receptor 7.
-1.7-2.7-3, for example, each insertion conveyor is driven by an intermittent drive machine v415 so that it can run and stop freely, and a detector 16 is placed at an appropriate position on each insertion conveyor. The detector 16 detects the veneers, and the signal activates each drive mechanism 15 to temporarily stop each veneer at a predetermined position and then start them all at once. With C as the reference veneer, when the core veneer C reaches the appropriate position, the back veneer B is stopped at a predetermined position.
This is done by appropriate means such as starting the front veneer F.

The support guide body 17 is a back veneer B that is fed from the insertion conveyor 9 to the position of the receiving body 7-1 in a direction perpendicular to its tltM.
The front end support guide 18 is provided for the insertion conveyor 10.
The supporting guide body 19 is provided for the core veneer C fed from the core veneer C in the fiber direction to the position of the receiving body 1-2.
1 to the receiving body 7-3 in a direction perpendicular to the fibers thereof.
The support base 21 is attached to, for example, the rond 23 of the hydraulic cylinder 22, and the operation of the hydraulic cylinder 22 moves each support guide and the front end support guide to the receiving position shown by the solid line in the figure. and the standby position shown by the dotted line. At the receiving position, each veneer is received from each insertion conveyor, supported and guided, and by the retreat, the front end surface of each veneer is brought into contact with the regulating member 6. Each veneer is released from the support and allowed to fall onto each receiver.

The support guides 17 and 19 support and guide the back and front veneers B and F that are being conveyed in the direction perpendicular to IN, so that the front end faces B a,
While bringing F a into contact with the regulating member 6, the receiver 7-1
．． Falling onto 7-3 W71. In general, veneers have a weak stiffness in the direction perpendicular to the fibers (this tendency is particularly strong in the case of thin or brittle ones, and the coefficient of friction in this direction is relatively large, so it is difficult to support and guide The body 17.19 is a bar-shaped body with an approximately circular cross section, and is made of a material that has a small coefficient of friction with the surface of the veneer, in order to ensure smooth and stable support guidance without bending or damaging the veneers. A material with a small aI friction coefficient is used only in the portion that contacts the object or the veneer surface, and the veneer is further stabilized to support and guide, and the veneer is bent due to the impact when the front end surface contacts the regulating member 6. In order to provide stiffness that will not cause damage, the front and back veneers F and B are curved in a convex curved shape as shown in Figure 4 (a). The fibers may be supported in a direction perpendicular to the fibers, or they may be supported in a direction perpendicular to the fibers at a plurality of locations in the IIN direction so as to form a concave curved shape as shown in FIG. 4(b).

The #i9 support guide body 18 supports and guides the core veneer C fed in the fiber direction, brings the front end surface Ca into contact with the regulation member 6, and causes it to fall and place on the receiver 1-2. , the core veneer C is generally rigid and strong in the direction of thickness<mN, and adhesive is applied to both the front and back surfaces, so the front end support guide 18 is not affected by the applied adhesive. In order to ensure smooth and stable support guidance of the core veneer C without giving too much force, reliable contact of the front end surface Ca with the regulating member 6, and drop placement on the receiver 1-2, the front end of the core veneer C is Use an L-shape or other shape that can support the entire width of the part. In this case, the position of the unloading end of the insertion conveyor 10 is set so that the front end face Ca of the core veneer C comes into contact with the regulating member 6 and the core veneer C is dropped and placed on the receiver 7-2. This is desirable.

To explain the implementation procedure, the detector 24 is installed at a position where the receiver 7 can be detected, for example, and detects that the receiver 7 has moved one pitch, and in response to the signal, the fluid pressure cylinder 22 is actuated to detect each support. The guides 17.19 advance the front end support guides 18 from the standby position to the receiving position, and also transmit the information via the timer to the intermittent drive 111 mechanism 15 to start each veneer from each insertion conveyor, and move each support guide and the front end. The support guide receives each veneer, supports and guides it, and retreats to the standby position at an appropriate timing, brings the fti end face of each veneer into contact with the regulating member 6, and drops and places each veneer onto each receiver. let it be placed The detector 25 emits a signal when the support base 21 retreats to the standby position, and the intermittent drive mechanism 8 is activated by the signal.
is actuated to move the receiver 7 one pitch (in the embodiment, downward in the reference plane X-x).

In the embodiment, when the receiver 7 reaches the position of the receiver 7-1 in the figure, the back veneer B is placed on the receiver 7 in the manner described above.
is dropped and placed with the front end surface Ba in contact with the regulating member 6, and then the receiver 7 descends one pitch and reaches the position of the receiver 7-2, and similarly the core veneer C is placed on the back veneer. Front end C on top of B
a is dropped and placed in contact with the regulating member 6, and when the receiver 7 further descends one pitch and reaches the position of the receiver 7-3, the front veneer F is placed on top of the two-ply veneer. The front veneer B, the core veneer C1, the front veneer F were stacked on the plywood structure 3 at the position of the receiver 7-3. A laminated veneer A is formed, and the front end surfaces Fa, Ca, and B a abut against the regulating member 6, resulting in a laminated veneer A with precisely aligned edges. The veneers are fed all at once from each insertion conveyor, and the support guides and front end support guides move forward and backward at the same time, making it possible to obtain three stacked veneers A in one process, resulting in high efficiency. This allows for a unique veneer structure.

In addition, at the first stage of the mechanism, two operations are added: one in which only the back veneer B is fed to the receiving body, and the next one in which only the back veneer B and core veneer C are fed to the receiving body, and the final At the stage,
By adding two operations, one for feeding only the core veneer C and the front veneer F to the receiver, and the other for feeding only the front veneer F to the receiver, a total of three stacked veneers A can be produced. In this embodiment, the back veneer B, the core veneer C, and the front veneer F are placed on the receiver 7 in order from the upper side in the direction of movement of the receiver 7. Back veneer B, core veneer C1 front veneer F
A polymerized veneer A in which the veneers are stacked is obtained, but by changing the arrangement order of each insertion conveyor, the polymerized veneers A can be obtained in which the veneers are stacked in a desired order. The same method can be carried out even if each veneer is placed in order on each receiving body.Furthermore, each support guide and front end support guide is provided with a hydraulic cylinder that advances and retreats, and each hydraulic cylinder is fed simultaneously. It can be implemented in the same manner even if it is configured to operate in the same manner.

In addition, in the present invention, only one end surface is aligned when stacking each veneer, but each veneer made of plywood has approximately the same size, and the other end surface adjacent to the one end surface to be aligned is aligned with each insertion conveyor. If they are aligned at this stage, just by aligning one end surface on the receiver, a polymerized veneer with the other end surfaces almost aligned can be obtained.

For example, as in the embodiment, the unloading means 26 is formed by stretching an endless belt around a rotary wheel attached to the shaft 3 and another rotary wheel 27 so that the traveling path of the endless belt crosses the traveling path of the descending receiving body 7. , when the receiver 7 carrying the polymerized veneer A crosses the endless strip track, it is received and transferred to the rotating wheel 27 side,
It is deposited in a deposition area such as a table lifter installed near the end of the table.

In addition to using such an endless belt, the conveyance means may be any other suitable means such as a fork-shaped receiving body that is movable back and forth between the receiving body 7 and the depositing place. It may be transferred to the press process without being deposited in the field.
