Abstract

PURPOSE:To transfer a veneer without damage thereto regardless of the extent of curl of said veneer which is cut out by always urging the veneer having been cut out against the travelling surface of a belt under pneumatic pressure. CONSTITUTION:At the rear of the blade of a knife 1, a belt conveyor 2 is disposed at specified angles toward the rear of said blade with respect to a vertical plane and on the upper side of the travelling surface of a plurality of rows of belts 5 passing around an upper and lower belt pulleys 3,4, blowoff ports 12 of a nozzle 10 are spaced at a required distance. Blowoff ports 12 of a nozzle 10' are spaced a required distance along the upper travelling surface of a belt 15 of a transfer conveyor 14 for horizontally transferring a veneer and a conveyor section (a) is formed by connecting both the nozzles 10, 10' by an arcuate guide 16. Compressed air having properly adjusted pressure, which is sent to an upper urging part 6, is blown off through the ports 12 against a veneer having been cut out to urge it against the upper travelling surface of the belt 5, while curled parts of said veneer are being corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a veneer conveying device for transporting cut veneers in a slicer (veneer cutting machine 2).

(Prior art) A conventional veneer conveyor in a slicer [;-- A pair of belt conveyors are arranged with the running surfaces of each belt kept at a required interval, and the cut veneer is transferred to the back of the knife blade. It was carried out by guiding it within the above-mentioned interval, but the tree 11
The friction of the curl of the cut veneer differs depending on the thickness etc., and it is necessary to adjust the width between the pair of root traction surfaces. So, II adjustment unnecessary f
A highly efficient conveyance device is required.

(Invention or attempt to solve the problem) (11) This invention is concerned with the above-mentioned stagnation and the dust content of the curls of the bulk plate cut out by the slicer i, q<, *
j! We provide a veneer conveying device that can carry out veneer without any cut damage.

(Means for solving the problem of hunger) The first invention is the knife blade of the slicer.
:, throw the belt 7 conveyor 11 at an angle of ゛C towards the back of the blade of the knife against the vertical plane, and blow out 6 air at the required distance along the belt's launch height ↑. Air jets are provided oppositely on the "■" side of the belt conveyor at a required distance apart along the running surface of the belt of the horizontally arranged transfer conveyor. B and C are connected by a circular arc-shaped guide body, indicating a conveyor section.

The veneer conveying device εG-j in the slicer of the second invention carries the belt at the 11th part of the knife of the sticer (at a predetermined angle in the direction of the entry y* part of the knife from the vertical plane). A conveyor is arranged, and air jet ports are arranged opposite to each other at a required distance M along the two sides of the belt, and two transfer conveyors are arranged horizontally on the Elf of the belt conveyor. A pair of air jets C'I are installed at a required distance of 1 along the top running surface of the belt. A sliding guide section that guides the conveyor section and the conveyor section only in the front-rear direction and the left-right direction has an arc-shaped sliding platform that moves in an arc-shaped manner. .

(The cut out veneer is always pneumatically yanked out by the belt's running surface, regardless of the degree of force.) In addition, the conveyor section moves slowly due to the sliding component in the front and back direction of the TF4 clam, so the conveyor section is slow to move. IN dynamic component force source (-driven).

(Example) To specifically explain the present invention with reference to an example, as shown in FIG. As shown in the figure, a belt conveyor 2 is disposed at the first fathom of the knife 1 at a required angle toward the back of the blade of the knife 71 with respect to the vertical plane. 1. An upper pressing section 6 is disposed integrally with the belt conveyor 2 at a predetermined distance on the running upper surface side of the plurality of rows of belts 5, and the upper pressing section 6 is connected to the fifth As shown in the figure, a plurality of rows of vertical tubes 8 are integrally connected to the upper and lower guide tubes 7, and as shown in FIG. 1. The required number of nozzles 10 shown in FIG. 0~Upper press FE embryo 6 which appears to be placed opposite to the upper surface at a required distance
In the guide tube 7 on the side of
Similarly to the upper pressing section 6, the lower external pressure section 16 is also
A belt 1 of a transfer conveyor 14 is provided with a required number of nozzles 70 for each frame body and carries out veneers in a horizontal direction.
The jet ports 12 of the nozzles 10' are arranged oppositely along the running upper surface of the nozzle 5 at a required distance, and both nozzles 10
10' are connected by an arc-shaped guide body 16 to form a conveyor section and a support section.

On the other hand, the sliding guide section slides the front frame 19 onto the guide rails 18 arranged above the sliding table 17 in front.
2 through the front frame 1 as shown by the solid line in FIG.
The side sliders 22 of the frame 21 and body are guided by guide rules 23 integrally arranged on the left and right sides of the bed. At the top and bottom of the body 19, the bearing supports 24 of the belt conveyor 2 and the top 1 of the belt conveyor 2 are integrally connected, and the conveyor part a and the sliding guide part are integrated to form a veneer conveyor. is formed. In history, the drive of the belt conveyor 2 of the conveyor section was driven by a first helical gear (not shown) which was pivoted on the conveyor guide section and engaged with a lip rack fixed to the bed, which was then locked to the helical gear shaft. By connecting the sprocket and the sprocket locked to the lower pulley shaft 25 of the belt conveyor 2 with a chain, the sliding component of the sliding table 17 in the front and rear direction drives the belt 5 of the belt conveyor 2 via the helical gear. It turns out.

The veneer conveying device in the slicer 8 constructed in this way moves slowly to the sliding table 17 with respect to the swinging movement of the sliding table 17 which gives the knife 1 an arcuate trajectory, and the sliding component in the front and back direction is generated. The belt 5 is driven only when moving forward, that is, when cutting out a veneer.A one-way clutch is attached to the helical gear to transmit power when rotating in one direction. By jetting compressed air from the jet port 12 that has been force-fed to the pressing section 6 with an appropriate flow rate adjustment, the curled portion is corrected and pressed against the running upper surface of the belt 5, thereby preventing slippage. The sheet is also fed out reliably regardless of the degree of curl, and is guided by the arc-shaped guide body 16 at the bottom of the belt conveyor 2.
Even if the veneer is smoothly transferred to the conveyor 14, the compressed air ejected from the outlet 12 of the nozzle 10' of the lower pressing part 13 presses the veneer against the running upper surface of the belt 15, so the same applies. It can be transported reliably without slipping and without damaging the curled portion P.

(Effects of the Invention) As described above, according to the present invention, the veneer cut out with a knife is pressed against the running surface of the belt by air pressure, so it maintains a constant posture regardless of the degree of curl at the time of cutting out. The conveyor section is driven in slow motion using the longitudinal sliding component of the sliding table of the slicer body as a power source. This has the effect of being able to guide the veneer to the transport path in a labor-saving and reliable manner.
