2. Description of the Related Art Conventionally, when wood is put in a drying oven to be dried, a large number of pieces of wood are regularly arranged in rows and columns, and each of the aligned groups of wood is dried through a pier. The pallets for stacking are framed so that they can be carried inside, and they are stacked in multiple stages, for example, around 30 stages, and are carried into the drying furnace by a hawk lift, and the temperature and humidity inside the drying furnace are controlled appropriately. It is dried while being heated. By the way, it is used for stacking each group of timbers on a pallet for stacking in a multi-tiered manner on the pallet for stacking, while regularly aligning a large number of woods before putting them in the drying oven in several rows and columns. As a conventional crossing device, a wood alignment unit that regularly arranges a large number of woods in several rows and columns, and the woods are transferred to the wood alignment unit. The length of the woods is automatically measured during the transfer. A crossing device is known, which is composed of a wood transfer conveyor equipped with a measuring instrument for moving the wood, and a wood stacking part for stacking each wood group aligned in the wood aligning part on a stacking pallet in multiple stages. .

However, in the conventional apparatus, after the timber arranging table formed into a flat plate having a predetermined width and length for stacking is loaded into the timber arranging section and supplied, the length of each timber is transferred during the transportation of the timber transfer conveyor. While automatically measuring the length of each piece of wood that has been transferred to the end of the conveyor while being automatically measured by a pushing mechanism provided at the end of the conveyor based on the measured result, On the wood liner, one to several lines are aligned in a row in the horizontal direction (short side direction of the alignment table) and in the vertical direction (longitudinal direction of the alignment table) according to the length measured. After a group of timbers arranged in several rows and columns in the timber arranging section is automatically transferred to the timber stacking section side together with the timber arranging table and transferred to the pallet for stacking on the stacking section, the timber arranging is performed. Stand under the group of timber By cutting out and placing a group of timber on a pallet and placing several piers in parallel on the timber group at predetermined intervals so as to intersect each piece of timber, the next aligned (second and subsequent rows ) The timber group is sequentially transferred from the timber arranging section together with the timber arranging table so that each timber group can be stacked in a multi-stage manner through the pier. That is, the conventional apparatus is configured to automatically perform a series of operations from supplying timbers having different lengths to the timber aligning unit to stacking the aligned timber groups in a multi-tiered manner on the timber stacking unit. It was

However, the width of timbers stacked in multiple stages while being aligned in several rows and columns within the range of the crossing dimension determined by the crossing device of this type has a substantially constant width, but the lengths of the timbers vary. Therefore, while automatically measuring the material length of the wood during the transfer process (on the way) of the transfer conveyor that transfers the wood to the wood alignment part like the above-mentioned conventional device,
Automatically perform the alignment work in the timber alignment section based on the measurement result.For example, when arranging wood in a vertical line according to the stacking dimension, the length of the first wood that was transferred first is the vertical direction. If the timber of the timber length deducted from the stake size is not transferred and the timber that is longer or shorter than the timber is transferred, the timber is not sent to the timber alignment section and stocked elsewhere. Since it is necessary to carry out the alignment work while repeating the selection such as placing it in place or returning it to the starting end side of the wood transfer conveyor again, it takes time to automatically divide the wood. Further, although the conventional device repeats the above-described sorting several times, if the timber of the length subtracted from the timber length of the first timber is not transferred during that time, the preset number of sorting When the can is cut, long or short timber is finally supplied to the timber alignment section. Therefore, in the conventional device, as illustrated in FIG. 10, there is a problem that the end portions (cuts) 1 ′ of the timbers 1 aligned in a horizontal line cannot be aligned, that is, the so-called mechanism length efficiency (filling rate) is poor. It is an element that causes it. Since the mechanism length efficiency has a great influence on the suitability of the drying, it becomes a big problem in the forest industry in which wood is dried while using this kind of crossing device, and at the same time, its solution is desired. Further, since the conventional device controls the operation of each part by the computer, the equipment cost thereof becomes enormous, the manufacturing cost of the device itself becomes high, and the forest industry operator handling the stowage device invests enormous amount of money. Had to buy the device at.

Incidentally, the cross-sectional dimension is a length dimension in the vertical and horizontal directions in which a group of timbers regularly arranged in a vertical and horizontal row can be loaded into the drying furnace in the aligned state (interval).

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and aims to greatly reduce the time required for stacking work, improve the mechanism length efficiency (filling rate), and reduce the apparatus. It is an object of the present invention to provide a crossing device for drying wood, which is improved so that it can be provided at a low cost by making it possible to significantly reduce the manufacturing cost of itself.
