Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating dried veneers in a roll dryer.

It is well known that roll dryers have been widely used for drying veneers used for plywood intermediate boards, etc., but roll dryers are of a type in which the veneers are transported in the same direction as the fiber direction. Therefore, the basic veneer processing process in the entire plywood factory, in which the veneer is mainly transported in a direction perpendicular to the fibers, is somewhat incompatible, such as cutting equipment, cross-splitting equipment, etc. In order to connect the veneer to a processing device that transports and processes the veneer in a direction perpendicular to the fibers, it is necessary to adopt an irregular connection mode that does not follow the macroscopic veneer processing line. As a result, the overall required space tends to increase, and although rationalization through connection can be achieved, it is unreasonable as a processing mode.

That is, for example, "Fully automatic drying processing equipment for sized veneers" (Japanese Patent Publication No. 51-6724) includes a tendering device having a carry-in conveyor, a tendering device having a butt conveyor, and a butt conveyor on the carry-in side of the roll dryer. A receiving conveyor equipped with a yarn insertion device and a pusher is installed, and after horizontally stripping a plurality of sized veneers with thread in advance, they are carried into the roll dryer in the same direction as the fiber direction, and the roll dryer A series of processing mechanisms are disclosed in which a clipper with a carry-out conveyor, a loading space, etc. are arranged on the carry-out side of the paper, and the dry veneer is cut to a desired length and loaded. As is clear, the front and rear associated processing equipment protrudes significantly from the roll dryer main body in a direction perpendicular to the conveying direction, which tends to increase the required space, which is unreasonable as a processing mode.

In addition, if the processing capacity of a processing device such as a cutting device or a horizontal stripping device is inferior to that of a roll dryer, for example, as illustrated in FIG. A plurality of processing devices 4 each having a stacking space 5 are provided on both the left and right sides, and a plurality of conveyors 3 running on the left and right sides make it necessary to supply the dried veneer 2 to each processing device 4 on a 50-50 basis. Therefore, the required space tends to increase more and more, making the processing mode even more unreasonable.

On the other hand, as illustrated in FIG. 2, for example, the dried veneer 2 is transported 50/50 by a plurality of transport conveyors 3a that run separately on the left and right sides, and the transport conveyors 3a approach each other perpendicularly to the transport conveyor 3a. At the intersection with another conveyor 3b, the direction of conveyance of the dried veneer 2 is changed to a right angle, and the direction of conveyance of the dried veneer 2 is changed to a right angle, and the arrow a A treatment mode in which the fibers are fed in a direction perpendicular to the fibers is also proposed, but due to the variety of widths of the dried veneers to be treated, a significant reduction in the required space cannot be expected, and the dry veneer Since the conveyance direction must be changed manually, the effect of streamlining the process associated with the connection is significantly impaired, and furthermore, the dry veneer may be damaged due to manual handling, so it is not necessarily practical. do not have.

Furthermore, normally a large amount of wood powder remains on the dried veneer, which may cause deterioration of the performance of the processing equipment. When transferring and processing horizontally,
Since there is no opportunity to remove the wood powder, it is necessary to remove it manually in front of the processing equipment, which makes the work complicated.

The present invention has been developed to overcome the drawbacks of conventional processing methods as described above, and allows for a relatively narrow connection space immediately after the roll dryer, regardless of the width of the dried veneer to be processed. Therefore, the transport direction is changed to follow the processing direction of the macroscopic veneer processing line, so that the dried veneer can be fed in a direction perpendicular to the fibers to the processing device arranged parallel to the roll dryer. By providing a new processing method with an extremely rational configuration, it is possible to reduce the overall space required, and at the same time, it is possible to automatically remove the wood powder. Specifically, the dried veneer is transported horizontally from a roll dryer in the same direction as the fiber direction.
At the unloading position, the fibers are once turned upside down in the fiber direction, and while being transported in a direction perpendicular to the transporting direction of the roll dryer, the transporting direction is appropriately bent.
After changing the conveyance direction to substantially the same direction as the conveyance direction of the roll dryer, the fibers are again turned over horizontally and fed to a processing device for the next step in a direction perpendicular to the fibers.

According to the processing method having the above-mentioned structure, the dry veneer, which is inverted in the fiber direction, is transported in a direction orthogonal to the transport direction of the roll dryer, and the transport direction is appropriately bent. Regardless of the width of the dried veneer to be dried, its transport direction can be easily changed to follow the processing direction of the macroscopic veneer processing line with a relatively narrow connection space, resulting in This makes it possible to reduce the overall space required, including the processing equipment, and since the wood powder falls and is automatically removed when the machine is inverted, there is a risk that the work will become more complicated. It is very effective.

Hereinafter, the present invention will be explained in more detail with reference to an example of implementation illustrated in the drawings.

FIG. 3 is an explanatory plan view of a series of mechanisms used to implement the processing method according to the present invention.

Reference numeral 6 in the figure is an unloading conveyor disposed at the end of the roll dryer 1.
The dried veneer 2 sent out from the veneer is carried out horizontally in the same direction as the fibers.

Reference numeral 7 denotes a plurality of guide conveyors running separately on the left and right, which are installed in a bent shape as shown in the figure, at an appropriate distance from the carry-out conveyor 6. Initially, in the first half before the bent part, an inverted drying unit is installed. The plate 2a is guided and conveyed in half in a direction orthogonal to the conveyance direction of the rolled ear 1, then at the bent part, the conveyance direction is changed to a right angle, and then in the latter half after the bent part, it is gradually horizontally conveyed. The dried veneer 2 that is overturned is guided and conveyed in the same direction as the conveyance direction of the roll dryer 1.

Reference numeral 8 denotes a plurality of auxiliary guide conveyors disposed opposite to the bent portions of each guide conveyor 7, which facilitate the change in the conveyance direction of the inverted dried veneer 2a by each guide conveyor 7.

Reference numeral 9 denotes a plurality of first receiving conveyors disposed below the front half of each guide conveyor 7 and running separately on the left and right sides, which receive one end in the fiber direction of the dried veneer 2 falling from the carry-out conveyor 6; The dried veneer 2
The dried veneer 2a is turned upside down in the fiber direction, and in cooperation with the front half of each guide conveyor 7, the dried veneer 2a is turned upside down.
is guided and conveyed in a direction orthogonal to the conveyance direction of the roll dryer 1.

10 is a plurality of second receiving conveyors disposed below the rear half of each guide conveyor 7 (preferably at the same height as the first receiving conveyor),
In cooperation with the rear half of each guide conveyor 7, the dry veneer 2 that is falling is guided and conveyed in the same direction as the conveyance direction of the roll dryer 1.

Reference numeral 11 denotes a plurality of regulation conveyors installed opposite to each other in the rear half of each guide conveyor 7.
In the latter half of the process, the dry veneer 2 is smoothly turned over horizontally again.

The processing method according to the present invention is carried out using a series of mechanisms configured as described above, for example.
The dried veneer 2 is transported horizontally from the roll dryer 1 through the transport conveyor 6 in the same direction as the fiber direction.
Once placed upside down in the fiber direction on the first receiving conveyor 9, the bent portion of the guide conveyor 7 is conveyed by the guide conveyor 7 and the first receiving conveyor 9 in a direction perpendicular to the conveying direction of the roll dryer 1. At , the auxiliary guide conveyor 8 obtains an auxiliary action, bends its conveying direction at right angles, and converts it to the same direction as the conveying direction of the roll dryer 1, and then obtains the regulating action of the regulating conveyor 11, gradually It is again turned over horizontally and fed in the direction of the fibers to the processing device 4 for the next step.

According to such a processing method, the dry veneer 2a, which is inverted in the fiber direction, is transported in a direction orthogonal to the transport direction of the roll dryer 1, and the transport direction is bent at right angles, so that the processing is easy. Regardless of the width of the dried veneer 2 to be processed, the transport direction can be easily changed to match the processing direction of the macroscopic veneer processing line with a relatively narrow connection space, resulting in This makes it possible to reduce the overall space required, including the processing equipment, and when the machine is inverted, the wood powder falls and is automatically removed, which makes the work more complicated. It is safe and effective.

In the above embodiment, a plurality of related processing devices were installed to process the dried veneer sent out from the roll dryer equally, but the processing stress of the processing device in the next step was If the processing capacity is superior to that of a roll dryer, there is no need to split the processing between multiple related processing devices, and although not shown in the diagram, it is possible to install related processing devices only on either the left or right side. You can set it up and process it all by yourself. In addition, in the case of 50/50 processing, if necessary, for example, at least one of the guide conveyors in the above embodiment may be provided in the opposite direction to that in the above embodiment to bring each processing device closer together. It is also possible to set it as a state.

In addition, since the dried veneer, which has remarkable flexibility in the direction orthogonal to the fibers, is bent appropriately in the direction orthogonal to the fibers, the degree of bending is not limited to the right angle as in the above example, but may be greater than or equal to the right angle. It is possible to bend the dried veneer to the following arbitrary degree, and the point is that the conveyance direction of the dried veneer to be fed perpendicularly to the fibers is approximately the same direction as the conveyance direction of the roll dryer, that is, the macroscopic veneer It is sufficient if the conversion can be performed along the processing direction of the processing line.
