Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) The present invention aims to remove the curls of a veneer veneer which is greatly curled toward the front side due to back cracking during cutting with a veneer lace, and straighten it flat. Cut out defective parts such as irregular edges and cracked 9-node holes in the board, and then cut again the parts that reach the total length of the veneer veneer during the measurement, and remove the chips. This invention relates to a veneer veneer correction cutting and distributing device that eliminates the veneer veneer from the machine and once collects the veneer veneer of the integrated standard length and then distributes it to desired stages of a multi-stage veneer dryer without any cuts. .

As a conventional device of this kind, for example, the Japanese Patent Publication No. 5'5-31
There is a device disclosed in No. 201, Method of Handling Green Veneer for Plywood, but this kind of conventional device intermittently transports the veneer veneer cut with veneer lace and converts it into a sizable veneer. The veneer veneers are cut and separated into chips, and the veneer veneers in the sizing are separated from the swarf, and the intervals between the veneer veneers in the sizing are brought closer to each other, and while the veneer dryer is being inserted, the veneer veneers are cut to approximately equal lengths and kept constant. The nine types of conventional devices have a curl correction function for veneer veneers and a fixed length veneer group, that is, a set of integrated length medium reinforcement. A put-time is involved each time the veneer veneers that have been cut into sections are collected and delivered to the subsequent process, so the continuous collection and distribution functions are lacking, and each stage of a multi-stage veneer dryer is flattened. It was previously impossible to collect length-cut veneer veneers continuously in one hour and distribute them to subsequent processes at high speed. A continuous type of veneer veneer that enables correction of curls, cutting of defective parts to a certain length, cutting to a fixed length, removal of chips from the machine, continuous collection of medium reinforcements to a fixed length without put-time, and distribution without a cutoff. The purpose is to develop a corrective cutting and distributing device.

(Configuration of the Invention) The configuration of the present invention will be described below with reference to the drawings, which are examples of implementation.

Tenderizer 1 that corrects curls in veneer veneer,
A veneer clipper 2 that cuts the veneer veneer connected to the tender riser 1 into lengths 1] and 1], and removes the chips connected to the veneer clipper 2 outside the machine and during the length measurement Conveyor 4a that collects plywood veneers in multiple stages
, 4b, and a tipple conveyor 6 that distributes the collected veneer veneers in the cumulative length delivered separately from the collecting conveyors 4a and 4b to the multi-stage veneer dryer 5 of the desired stage. It is configured.

Next, to explain the present invention along with the flow of the veneer veneer, first, the curled veneer veneer conveyed by the conveyor 7 has a rounded convex part with a small radius of curvature on the outer periphery of the roller, and a rounded convex part with a large radius of curvature on the outer periphery of the roller. The pressing and bending action of the tenderizer 1, which consists of a pair of upper and lower pressing rollers 1a, 1b, etc., which are elongated in the axial direction with equal pitches and rounded concave portions, continuously creates new surface cracks in the material on the front side. Insert it to flatten the curl caused by cracks in the back during cutting. Since there are defective parts such as irregular edges and cracks in the veneer veneer that has been flattened by the tenderizer 1, the sum of the defective parts and the individual boards d] is In order to cut the reached point, the roll ambience v2a and rotary knife 2b are placed vertically 71, and a limit switch is placed on the conveyor 8'' in front.

A sizing cutting mechanism in which veneer detectors 2C each consisting of a photoelectric switch or the like are arranged in a row in a direction orthogonal to the conveyance direction, and an integrated length cutting mechanism in which a pulse counter or the like is arranged in relation to the conveyor 8. This is automatically cut by a veneer clipper 2 equipped with a dual-use mechanism. Said veneer clipper 2
The veneer veneers that have been continuously cut by the machine are transported with almost no gaps between the cut points. Existing veneer veneers can be sorted alternately into multiple stages of collection conveyors 4a and 4b into integrated standard medium bars.A needle bell (3a) is provided in the middle part of the veneer clipper 2 to provide a synchronization signal for the cutting location by the veneer clipper 2. A veneer divider roller comprising a plurality of retractable sorting bars 3b and 3c and a needle removal roller 6d removes the entire amount of incoming veneer veneers. The veneer veneers of the cumulative standard length medium bars distributed alternately on the gathering conveyors 4a and 4b are brought together at each stage by intermittent conveyance, and then the veneers are brought together at each stage. The veneer veneer is taken out alternately and delivered to the tipple conveyor 6 without any breaks, and at this time, the conveyance direction of the veneer veneer is from the direction perpendicular to the direction of the fibers delivered from the previous collecting conveyors 4a and 4b. The direction is changed perpendicularly to the parallel direction, and the sheets are delivered one by one on the tipple conveyor 6. In addition, the tipple conveyor 6, the roll conveyors 5a, 5b, 5C of the Id-multistage veneer dryer 5
, 5t1, the accumulated veneer veneers of the cumulative standard length, generally equivalent to the inside of the roll conveyors 5a, 5b, 5c, 5d, are continuously distributed in synchronization with the conveyance speed. It is configured to do so.

(Effects of the Invention) As described above, the present invention includes a tender riser 1 for straightening curls, a veneer clipper 2 for cutting during sizing and total length measurement, and a veneer clipper 2 for separating chips to the outside of the machine and integrating them. a veneer divider 3 for distributing veneer veneers of regular length and medium reinforcement into two stages of collecting conveyors; and the collecting conveyor 4a,
4. Corrective cutting of continuous type veneer veneers formed in a series of processes consisting of a tipple conveyor 6 that distributes the aggregated veneer veneers in the cumulative length delivered from 4b to the desired multi-stage veneer dryer 5. Since it is a distribution device, when using the present invention, curled veneer veneers can also be treated as tenderizer 1.
As a result, a new surface crack is created, the curl is corrected, and the surface is flattened, so that the mutual plate spacing can be brought as close as possible on the collecting conveyors 4a and 4bl, and the plates on the collecting conveyors 4a and 4b of 1 and 2 stages can be brought closer to the limit. Since the veneer veneers gathered at each cumulative standard length 1 can be delivered alternately onto the tipple conveyor 6, there is no put time for collection and delivery, and they are delivered seamlessly to the multi-stage veneer dryer 5. Therefore, it can be safely and efficiently fed to the subsequent drying process without problems such as bending diagonally, becoming heavy, bending, or wasting process time during the conveyance process. This is an invention with remarkable implementation effects.
