Description

[Detailed Description of the Invention] The present invention provides a veneer veneer of a predetermined length (hereinafter referred to as veneer).
This article relates to a veneer stacking device that stacks two sheets of veneer and then carries them out, and aims to significantly contribute to the veneer stacking process in plywood manufacturing by providing a device that can handle increased processing speeds. It is.

Conventionally, there is a device of this type that performs the above-mentioned stacking process on veneers that have been cut to a predetermined length. It was necessary to accurately detect the mutual position, shape, etc. of two veneers, and to quickly control them.

However, it is extremely difficult to detect and control the various conditions of the veneers to be laminated as desired due to the presence of defects peculiar to veneers such as cracks, curls, chips, and burrs, and this also reduces the processing speed. These limitations have led to the diversification of improvement detection means and the sophistication of control, and as a result, this type of device has become extremely complex.

In order to fundamentally solve the problems that conventional devices have, the present invention includes a veneer stacking device that incorporates a cutting device that cuts the veneers into a predetermined length, and thereby This eliminates the need to specifically detect and control veneers of a predetermined length, simplifying the equipment and improving processing capacity.
The details are as follows.

That is, as the embodiment device is shown in FIG.
It is equipped with a cutting discrimination device according to the invention, two conveyors 5 and 6 are provided in parallel in connection with the device, and the length of the veneer 2 cut to a predetermined length is further provided over a substantial conveyance distance. The two transport conveyors 5 and 6 are arranged with a distance difference of an odd multiple of
The gist is that it was constructed by merging the following.

As is clear from the figure, the veneer 1 supplied to the apparatus of the present invention is first cut into a predetermined length, and then transported by two conveyors, and as a result, the veneer 1 of a predetermined length is
Stack two sheets at a time and transport them.

To be more specific, first, the veneer detector 8 detects the supplied veneer 1, sends a detection signal to the control mechanism 10, and the control mechanism 1 detects the veneer using an integrating device such as a trowel counter. 1, and each time the set length is reached, the operating mechanism 9 of the cutting blade 7 is activated, and the cutting blade 7 is rotated in one direction from the bottom to the top or from the top to the bottom. Each time, a veneer 2 of a predetermined length is created. At the same time, the veneers 2 are discriminated alternately from the carry-out conveyor 5 to 6 or from 6 to 5. On the other hand, two conveyors 5 continue to convey the discriminated veneers 2.
and 6 is “driven by the drive mechanism 11,
Although not shown in the figure, since there is a distance difference as described above, one side takes a detour compared to the other, and then
Both of them meet at a merging point 4, and the two veneers 2 can be overlapped. The drive mechanism 11 is operated by the control mechanism 10 based on the detection signal of the single plate detector 8 as necessary.
ON/OFF control is also possible, and by doing so, even if the supply of veneers 1 is interrupted, the drive mechanism 11 will be turned OFF, and both conveyors will stop without disturbing the mutual relationship of the conveyance states of the veneers 2. be able to.

In addition, as shown in the figure, it is desirable that the cutting discrimination device has the function of discriminating at the same time as cutting.
It is also possible to use a device that combines the cutting mechanism and the discrimination mechanism. In any case, according to the device of the present invention, cut veneers can be reliably stacked without the need for special detection or control, and therefore, the device can be extremely simplified and its processing capacity can be significantly improved. If possible, 1
In an average plywood factory that processes tens of thousands of veneers a day, it is possible to process not only veneers cut from veneer lace, but also veneers that have been reeled and rewound. This provides a device with high utility value.
