Description

The invention relates to forestry equipment and can be used in the forestry and woodworking industries.

There is a known technology for the preparation and supply of sawn raw materials in the form of round assortments of certain diameters and lengths (Fig. 2.29, 2.31, 2.33 and a description of the lines in the book "Technology and design of timber depots. A study guide for universities" / A.K. Redkin, V.D. Nikishov, A.K. Sukhanov, A.A. Shadrin. - M .: Ecology, 1991, 288 p.).

To implement this technology, production lines are used to cut logs into logs of the LO-15C type and sorting conveyors to sort the assortments by size.

However, the use of such technology and equipment leads to the supply of an excess of wood, which takes up space during transportation, and turns into waste when processing round assortments. Moreover, it is not recommended by the decisions of federal and regional bodies, and in some cases, the sale of round timber as raw material is prohibited.

A known line for the preparation of raw materials containing the loading device installed along the technological process and kinematically connected with each other, a cross-cutting machine, a wood distributor, a transmission device, a longitudinal splitting machine and an outlet conveyor (A.S. No. 1158348, MKI V 27 V 31/00 - prototype).

However, this line is intended for the preparation of raw materials for the manufacture of chips and cannot be used for the preparation of sawing raw materials.

The invention is aimed at solving the problem of simplifying the technology for preparing raw materials at a processing plant, reducing waste processing costs, increasing transportation volumes by supplying raw materials in processed form, with improved loading of rolling stock and the possibility of transporting it in packaged form.

This is achieved by the fact that it includes a debarking machine and a sorting conveyor, a packaging section, storage of finished packages and a shipment section for vehicles, and a longitudinal sawing machine is made in the form of a trellis machine with a carriage with a clamp mechanism for round timber, a tilter, a mechanism longitudinal movement and saw block.

The invention is illustrated by drawings, where figure 1 schematically shows a line for the preparation of sawing raw materials, top view; figure 2 is a General view of the half-beam; figure 3 - package of half-bars prepared for shipment to the consumer, side view; in Fig.4 - a package of half-bars prepared for shipment to the consumer, view A in Fig.3.

The sawmill preparation line includes a loading device 1, a longitudinal conveyor 2, a debarker 3, a longitudinal conveyor 4, a longitudinal sawing machine 5, a sorting conveyor 6, a packaging section 7, a storage area for 8 packages and a shipping area for 9 packages for vehicles.

The machine for longitudinal sawing 5 is made in the form of a trellis machine having a carriage with a clamp mechanism for round timber, a tilter, a mechanism for longitudinal movement and a saw block. The machine for longitudinal sawing can also be made in the form of a band saw or a saw frame.

The line works as follows.

Sawing raw material enters the loading device 1, from which it is individually delivered to the longitudinal conveyor 2 and to the debarking machine 3. The barked round timber through the longitudinal conveyor 4 is fed to the longitudinal sawing machine 5. The diameter can be measured manually using a ruler or an automatic diameter meter. Based on the diameter measurement data, the height of the beam and the height of the removed segments are set. To remove segments, they are used by lacquering machines, band and circular saw machines or saw frames. During longitudinal sawing from opposite sides of barked round timber, segments are removed parallel to the longitudinal axis and a half-bar 10 is formed - an unedged 2-edged bar. The height (h) of the half-beam 10 is equal to the total coverage of the top diameter of the log plus the maximum shift of the beam on the machine of the 2nd row h = (dα _pl + Δ _max ). Such a height of half beams allows you to get from it as much lumber as from a log.

The half-bar 10 enters the sorting conveyor 6, where the half-beams are sorted by height and length. The resulting half-bars 10, after sorting by the height of the beam and the length at the packaging section 7, are placed in transport packages 11. To create denser packages, gaskets 12 are used, which are installed in the top of the half-bars. Received packages 11 are tied with wire 13 or other binding materials. This allows loading and transportation of whole packages 11. Ready-made packages are located at the storage area of 8 packages. At the shipment area of 9 packages 11 for vehicles, cranes or forklift trucks are used, with which packages are loaded onto vehicles for transportation to sawmills.

The use of the line for the preparation of sawing raw materials in timber industry enterprises allows to reduce the volume of transported wood (to exclude unnecessary wood segments), and at the same time to get the same amount of lumber.

At the consumer (at sawmills and sawmills), half-bars 10 are fed into the sawing machines of the 1st row with fixed feed mechanisms with the plates up and down, and the 2nd row with the side plates. This will improve the conditions for supplying raw materials to processing machines, their basing and processing accuracy.

The use of the line for the preparation of sawing raw materials does not require a radical reconstruction of the production either from the supplier or the consumer, since it is based on the existing equipment.

The economic effect of the supplier can be obtained by increasing the price of the supplied raw materials and the supply of processed raw materials (rather than round raw), reducing the cost of transporting raw materials and increasing the safety of transportation.

The economic effect for the consumer can be obtained by reducing the cost of preparing raw materials for processing (debarking, partial longitudinal sawing, sorting) and improving the conditions for supplying raw materials to processing machines, their basing and processing accuracy.
