Abstract

PURPOSE:To feed veneers alternatively in reverse direction by pushing the rear end of zigzag portion while winding medium through rotation of reel. CONSTITUTION:Pushing bodies 7, 7' are arranged near to the zigzag ends while retreating slightly from the feeding face for adhesive coating systems 6, 6' arranged to the right and left of an elevatable table 1. The feeding face and the position of the uppermost veneer 5 on the pallet 2 are maintained at approximately same height through elevation of said table 1 and the medium 3 is wound through rotation of reel 4. The uppermost zigzag portion is pulled up as the medium 3 is wound to lift the rear end of veneer 5 positioned on the medium 3 thus to operate a push body 7 synchronuously to push the rear end of said zigzag portion. Consequently, the veneer 5 is transferred to the left and fed to the left adhesive coating system 6'.

る作業性を著しく低下させていた。Conventionally, when paying out only the topmost veneer veneer from a pile of veneer veneers, it was held by suction using a vacuum suction mechanism, or it was stuck and held by the piercing action of a needle-like object. However, since two or more veneer sheets are often fed out at the same time, the workability in the next process is significantly reduced.

A state in which veneer veneers are lightly adhered to each other during stacking due to simultaneous suction of the first veneer veneer, resin-containing wood, or tape attachment found in repaired veneers. Due to the fact that the veneer veneer itself is kept in a moderately moist state, there may be a concomitant rise in the temperature, or depending on the type of wood, there may be negative pressure generated between the veneer veneers. A phenomenon was observed in which the second and subsequent veneer veneers were simultaneously adsorbed.

基づき説明する。In view of the above, the present invention has been developed by pressing the plywood veneer stacked between the flexible inserts on the pallet of the lifting platform onto the zigzag folds 94 of the inserts while winding up the inserts. An example of this will be described below with reference to the accompanying drawings.

されている。A pallet 2 is placed on the lifting platform 1, and its upper surface position is always maintained at a constant height by an appropriate detection device. At one end of the pallet 2, there is a starting end of a flexible insert 3 made of woven fabric, synthetic resin, twisted yarn, etc., which is wide across its entire width, or has a mesh or lattice shape. is locked.

A veneer veneer 5 is stacked between the inserts 8 which are arranged in a zigzag shape and are vertically adjacent to each other.

The entire insert 3 is wound up as the reel 4 rotates while always maintaining the same height.

Therefore, the veneer veneer 5 is transferred to the left,
It is fed out to the adhesive applicator 6' on the left side.

The next veneer unit 5 is fed out to the adhesive applicator 6 on the right side.

ものである。As described above, according to the method of the present invention, the terminal end of the flexible insert member is locked at a position above the lifting table, and -M is rotatably supported, and the starting end is attached to the pallet on the lifting table. A pushing body is provided in the vicinity of both ends where it is locked and forms a serpentine fold, retracted slightly above the feeding surface, and while winding up the insert by rotation of the reel, presses the rear end of the zigzag fold. Since the veneer veneers stacked between the intervening bodies are pushed by the body and fed out alternately in opposite directions, the drawbacks of the conventional method described above can be eliminated, and the veneer veneers can be reliably separated without being damaged. Then, it can be sent to the next step.
