Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for treating veneer veneers delivered from a continuous dryer.

Recently, as the performance of veneer cutting machines for cutting unnecessary parts of veneer veneers (hereinafter simply referred to as veneers) and veneer joining machines for joining multiple veneers has improved, continuous By connecting the P-layer and the post-processing machine such as the veneer cutting machine or veneer joining machine with a conveyor, the processing space, the number of processing personnel, and the damage to the veneer can be reduced. Attempts have been made to enable rationalization of the veneer processing process after the veneer dryer, but the veneer feeding capacity of the continuous dryer is If there is a temporary mismatch between the veneer processing capacity of the post-processing machine and the veneer processing capacity of the post-processing machine, the excess veneer may not be able to be processed, and the worker may temporarily deposit the excess veneer in another location. When handling the veneer, problems such as tearing of the veneer may occur, which in turn worsens workability and veneer yield, hindering rationalization.

Therefore, for example, as illustrated in Fig. 9, a continuous dryer A
A cutting machine 29 that cuts the veneer S delivered from If the veneer supply capacity of the continuous dryer A temporarily exceeds the veneer processing capacity of the post-processing machine B, the veneers sent out from the continuous dryer A The cut veneer S is cut to a desired size or less by the cutting machine 29, and the cut veneer S is temporarily piled up by the stacking machine 30. After the veneer processing capacity of the post-processing machine B is restored, the pile pile 30 is marked with a dotted line. Shifting the veneer to the position shown, the veneer S is sequentially supplied to the insertion conveyor 2 of the post-processing machine B starting from the top one, and the subsequent veneer S is fed to the cutting machine 2 in the same manner as above.
At the same time, the cut veneers S are cut to an arbitrary size or less by the step 9, and the cut veneers S are temporarily piled up by the stacking machine 30, and the same operation is repeated sequentially to improve the veneer supply capacity of the continuous dryer A and the veneers of the post-processing machine B. Attempts have been made to adjust the processing capacity, but when such processing is carried out, workability and veneer yield inevitably deteriorate as the veneers are cut to smaller sizes than desired. This inevitably results in the effectiveness of the connection being halved.

The present invention was developed in order to eliminate the drawbacks of the conventional processing, and has an extremely simple and rational configuration that allows reduction of processing space, reduction of processing personnel, reduction of veneer damage, etc. The purpose of the present invention is to provide a veneer processing method and a device that contribute to the rationalization of the veneer processing process after the veneer dryer.

That is, in the veneer processing method according to the first aspect of the present invention, as illustrated in the process diagram of FIG. An intermittent conveying mechanism that is driven intermittently each time the veneers are sent out is used to gradually close the gaps between the veneers. A consolidated storage process C is provided, which comprises a storage and discharge process of sequentially winding and storing a plurality of veneers closely spaced, and unwinding and releasing them at appropriate times. The veneer S sent out from the continuous dryer A by the unloading conveyor 1 with the belt 1a is passed directly to the insertion conveyor 2 of the post-processing machine B for processing, without operating the post-processing machine B. In case of stopping, etc., operate the intensive storage process C and carry out the continuous dryer A by the unloading conveyor 1.
In addition to sequentially collecting and storing the veneers S delivered from the continuous dryer A, the veneers S are rewound to the insertion conveyor 2 of the post-processing machine B when the delivery of the veneers S from the continuous dryer A stops or when the number of veneers S is reduced. By discharging and processing, it is possible to adjust the temporary discrepancy between the veneer supply capacity of the continuous dryer and the veneer processing capacity of the post-processing machine, reducing the processing space and processing personnel. At the same time, damage to the veneer by the operator can be prevented, and the veneer processing process after the veneer dryer can be streamlined.

In the figure, 3 is a loading platform on which the treated veneer Sa processed by the post-processing machine B is loaded, and 4 is an upper stage delivery conveyor of the continuous dryer A (7).

In addition, the veneer processing apparatus according to the second invention of the present invention includes:
In order to narrow the distance between the veneers sent out from the continuous dryer, the veneers are intermittently 1 each time based on signals from the veneer detector that detects the veneers sent out from the continuous dryer.
A driven intermittent conveying mechanism is installed between the continuous dryer and the post-processing machine, and an appropriate mechanism is installed to sequentially wind up, store, and unwind and release multiple veneers closely spaced from each other at the appropriate time. Several reels that can be rotated in forward and backward directions and raised and lowered are used to guide the veneer to the outer periphery of the reels, and to wind up wire rods such as threads that are wound up and unwound together with the veneer.

A winding storage mechanism that can move forward and backward and has a wire rod dedication member is attached to the intermittent conveyance mechanism, and the wire rod is easily attached to and removed from the reel, cut, and can be recovered. Since this device performs winding and unwinding, it is a suitable device for implementing the veneer processing method according to the first aspect of the present invention.

That is, FIG. 2 is a side explanatory view for explaining the veneer processing apparatus according to the second invention of the present invention, and FIG.
FIG.

In the figure, reference numeral 8 denotes a belt constituting an intermittent conveyance mechanism, and a pulley 6 fitted to the shaft 5 of the delivery conveyor 1 so as to be freely rotatable.
and touch roll 7, and is controlled by a controller 19 based on a signal from a veneer detector 10 disposed at the end of the unloading conveyor 1. It is rotated intermittently every time the veneer S is supplied from the carry-out conveyor 1.

Reference numeral 9 denotes a reel that can be rotated in forward and reverse directions and raised and lowered, constituting the winding storage mechanism G, and in a normal state, for example, a lifting device 15a of a known IJ IJ song jack 15 as illustrated in FIG. 7 is used. When winding up the veneer S, it is lowered onto the touch roll 7 and moved in the forward direction (counterclockwise in the figure) via the touch roll 7. Furthermore, during rewinding, the rotation direction converter 18 and the intermittent drive device 18 connected to the insertion conveyor 2 intermittently rotate the tape in the opposite direction (clockwise in the figure) via the touch roll 7.

Reference numeral 12 denotes a wire rod dedication member constituting the winding storage mechanism G, which guides the veneer S to the outer periphery of the reel 9 and dedicates the wire rod 13 to be wound and unwound together with the veneer.

Note that one end of the wire rod 13 is fixed to the reel 9 in advance by a fixing means such as taping or winding.

Reference numeral 14 denotes a wire rod guide member that guides the wire rod 13 below the touch roll 7. Only when winding the veneer S, the wire rod guide member 14 guides the wire rod 13 to the touch roll 7 by operating a reciprocating device (not shown) consisting of a fluid cylinder or the like. It is moved forward through the formed groove 16 to be located below the touch roll 7.

The veneer processing apparatus according to the second aspect of the present invention is configured as described above, and when the post-processing machine B is temporarily stopped, the lifting device 15a of the reeling deck 15 lifts the reel. 9 is lowered onto the touch roll 7, and the wire guide member 14 is moved forward to be positioned below the touch roll 7 as shown by arrow a in FIG. 3, and the single plate detector 10 is activated. By this,
As is clear from FIG. 3, each time a veneer S is sent out from the continuous dryer A via the delivery conveyor 1,
is detected by the veneer detector 10, and the intermittent drive device 11 is controlled by the controller 19 based on the signal from the veneer detector 10.
Since the belt 8 of the intermittent conveyance mechanism is rotated intermittently, the mutual spacing of each veneer S can be narrowed, and each veneer S whose mutual spacing has been narrowed will eventually be transferred to the touch roll. When the reel 9 reaches the position of the reel 9, which is rotated intermittently in the forward direction via the wire 13, the wire rod 13 restricts its progress and guides it to the outer circumference of the reel 9. It can be stored collectively as ball F.

On the other hand, if the delivery of the veneer S from the continuous dryer A is stopped, etc., the wire guide member 14 is moved back to the predetermined position as indicated by the arrow in FIG. By operating the intermittent drive device 18,
As is clear from FIG. 4, the rotational direction converter 18 and the intermittent drive device 18 intermittently rotate the reel 9 in the opposite direction via the touch roll 7 to rewind the rolled ball F.
Each discharged veneer S can be fed one after another to a post-processing machine B.

In addition, when the veneers S sent out from the continuous dryer A are sequentially wound up and collectively stored as rolled balls F, the veneers S sent out from the continuous dryer A are subsequently supplied to the post-processing machine B. In preparation for rewinding, the wire guide member 14 is moved back to a predetermined position, and the reel 9 (wound ball F) is temporarily raised above the touch roll 7 by the lifting device 15a of the reeling deck 15, and the reel There is no problem if you make it wait.

Furthermore, FIG. 5 is a side view for explaining another embodiment of the veneer processing apparatus according to the second invention of the present invention, and its configuration is similar to the embodiment illustrated in FIGS. 2 and 6. Almost the same as the example, the reel 9 constituting the winding storage mechanism G includes a plurality of lifting devices 25, 26 and a reciprocating reel transfer path 20.
A plurality of veneers are normally stored in a double reeling deck E having a veneer 21, and when winding a veneer S, they are lowered one by one onto the touch roll 7 via a lifting device 25, The veneer S is intermittently rotated in the forward direction (counterclockwise in the figure) via the roll 7, and after the winding of the veneer S is completed, the double IJ is moved by the lifting device 25.
The rolls are transferred to the feed path 20 of the IJ block E, and when rewinding, the rolls are lowered one by one via the lifting device 26 onto the touch rolls 7a of the intermediate conveyor 24 that connects the intermittent transport mechanism and the insertion conveyor 2. The touch roll 7a is rotated intermittently in the opposite direction (clockwise in the figure) by the drive source 22 and the intermittent drive device 23, which can freely rotate in forward and reverse directions, and in synchronization with the rotation of the insertion conveyor 2. At the same time, after the unwinding is completed, the wire rod dedication member 12 is moved to the rewinding path 20 of the double reeling deck E by the lifting device 26. 7a, respectively, and are replaced as necessary.

According to the apparatus configured as described above, when the post-processing machine B is temporarily stopped, the reel 9 is moved by the lifting device 25.
is lowered onto the touch roll 7 and the veneer detector 10 is activated, so that each time a veneer S is sent out from the continuous dryer A via the delivery conveyor 1, a signal from the veneer detector 10 is detected. Under the control of the controller 19 based on the base controller 19, the intermittent drive device 11 intermittently rotates the belt 8 of the intermittent conveying mechanism. When each of the gathered veneers S reaches the position of the reel 9, its progress is regulated by the wire 13 and guided to the outer periphery of the IJ-le 9 in sequence. The wire rods 13 can be collected and stored, cut, and transferred to the outgoing feed path 20 of the dual reeling deck E by the lifting device 25. If necessary, the wire rods 13 can be cut and transferred to the outgoing path 20 of the multiple reeling deck E. It is also possible to store a plurality of balls F) in the outward feeding path 20.

On the other hand, rewinding can be carried out at any time depending on the recovery of the veneer processing function of the post-processing machine B. The reel 9 is rotated intermittently in the opposite direction via the touch roll 7a by lowering the reel 9 upward and operating the drive source 22 and the drive device 23 intermittently. Since the spool F is unwound, each discharged veneer S can be sequentially supplied to the post-processing machine B, and the thermal wire can be used repeatedly without waste by collecting it in the wire dedication member. .

Furthermore, as mentioned above, since unwinding can be carried out at any time depending on the recovery of the veneer processing function of the post-processing machine B, all the veneers S sent out from the continuous dryer 8 are wound up and stored collectively. However, if necessary, if the veneer S sent out from the continuous dryer A is directly supplied to the post-processing machine B, the wire rod 13 may be After cutting, the reel 9 (rolled ball F) is temporarily raised above the touch roll 7 by the lifting device 25, and the drive source 22 is reversed to rotate the intermediate conveyor 24 in the opposite direction to that during rewinding. There is no problem if you do that.

In any of the above-mentioned embodiments, the controller 19 controls the controller 19 based on the signal from the veneer detector 10 installed at the end of the unloading conveyor 1, so that the intermittent Although the belt 8 of the conveyance mechanism is configured to rotate intermittently, for example, as illustrated in FIG.
A rotating pressure roll 28 is provided at the end of the belt 8 of the intermittent conveyance mechanism.
It may be configured to rotate intermittently, and if the interval between the veneers S sent out by the unloading conveyor 1 is relatively narrow, the intermittent operation of the intermittent conveyance mechanism is stopped and the veneers are rotated continuously. There is no problem in rotating the veneer S and winding it in the feeding state, but in any case, as exemplified in each of the above embodiments, the reel 9 of the winding storage mechanism G is connected to the intermittent conveyance mechanism. If the structure is such that the feed is rotated intermittently in the plane direction, a drive source for the feed for winding is not required, and synchronization with the intermittent conveyance mechanism can be achieved extremely reliably, which is extremely convenient.

As is clear from the above, according to the present invention, by reducing the distance between the veneers after the continuous dryer and by storing and releasing the veneers, the operation of the continuous dryer is not stopped.
The insertion of veneers into the post-processing machine can be stopped or enhanced at any time, and temporary discrepancies between the veneer supply capacity of the continuous dryer and the veneer processing capacity of the post-processing machine can be adjusted. , reduction in processing space, reduction in processing personnel,
It is possible to streamline the veneer processing process after the veneer dryer, including reducing damage to the veneer.
