RU64609U1 - AUTOMATED SIZE LINE FOR SIZE-SHAPED-ROLLER TYPE WITH ADDITIONAL SECTIONS OF TWO-SIDED RESET - Google Patents

Abstract

The claimed automated line can be used for automated sorting of lumber, in enterprises with small and medium production volumes. An automated line for sorting lumber containing a control panel, a sorting table with a sliding gate mechanism and a reversing conveyor divided by the width of the partitions into corridors, external sorting conveyors with corridors that are a continuation of the sorting table corridors, lumber dumping devices, at the end of the corridors of the portable conveyors and in plan stepwise located drives (reception tables). It differs from the known analogues by the presence at the ends of the central sorting corridors of additional sections of conveyors with two-sided dumping of sawn timber into drives. The result of the proposed technical solution is to simplify the design, reduce the metal consumption and manufacturing cost of the sorting line in terms of one sorting place. Using the proposed technical solution, sorting lines with sorting fractionality from 8 to 20 can be manufactured. It can be implemented in industry using standard equipment, non-deficient materials and components at any domestic timber industry enterprises.

Description

The utility model relates to the woodworking industry and can be used to create mechanisms designed to mechanize sorting of sawn timber at sawmills and woodworking enterprises, with small and medium production volumes.

Currently, large sawmills use automated sorting lines of domestic and foreign production for the sorting of sawn timber with the transverse movement of the boards by sorting conveyors. These lines have high performance (up to 40 or more boards per minute), but are bulky (weight from 60 tons or more), and expensive. When using them, the formation of drying stacks or transport bags directly in the line stores is practically impossible, therefore, packs of boards obtained during sorting must first be removed from the sorting zone and then transported for subsequent transfer with the formation of drying stacks or transport packages, their description and characteristics are given in the sources (Shimkevich Yu.B. - Handbook on lumbering. Publishing House ProfiKS St. Petersburg. 2003. 195 s, Silaev V.I. Mechanization of work in warehouses of lumber in. Moscow. Publishing house "Forestry industry. 1980. 123 S.), (analogue-1).

In sawmills with medium and small volumes of production, as a rule, “sorting sites” (transverse 4-5 chain conveyors) with manual sorting of boards are used. The labor costs for sorting with their use make up from a quarter to half the labor costs of the entire sawmill. It is impossible to form drying stacks and transport packages at the sorting sites as well as the mentioned automated sorting lines without turning or transporting and re-shifting lumber, which significantly reduces labor productivity in enterprises.

In connection with the foregoing, the problem arose of creating for enterprises of small and medium-sized lumber production inexpensive automated sorting lines with the longitudinal movement of the boards, since manual labor on sorting is excluded on such lines, and drying stacks and transport packages can be formed directly near the line, without re-shifting the boards , which also provides a reduction in manual unproductive labor.

Known sorting line with the longitudinal movement of lumber, for small sawmills, (Zanegin L.A. and others. Line for

sorting of lumber and beams “Woodworking industry No. 4, 2003. 7, 8. p.)

The line includes a longitudinal roller conveyor with extendable stops and transverse chain conveyors with pushers for dumping boards into drives located on both sides of the roller conveyor. The need to install transverse conveyors against each pair of drives and retractable stops complicates and increases the cost of the sorting line. The line capacity is 5-6 boards per minute, which is not enough with average production volumes, (analogue-2).

It is also known sorting device (Silaev V.I. Mechanization of work in the warehouses of lumber. Moscow. Publishing House "Forest Industry". 1980., 21, 22 S.), made in the form of slider shutters slanted in one line. Controlled gate valves form a ramp along which the boards, when the shutters are opened, fall onto the remote conveyor belts and are transported through them to drives. Such a switchgear is simple in design and reliable, but can only service a limited number of drives, usually up to four (analog-3).

Known drive boards ND-2 (Shimkevich YB - Handbook for sawing. Publishing house "ProfiKS" St. Petersburg 2003., 195 S.) in the design of which are laid rollers with screw winding and angles (shields) installed to dump lumber in drives, this device is used only as a drive boards, (analog-4).

Known (patent for utility model No. 56358 with priority dated January 26, 2006, article by Reutov Yu.M. Solving the problem of sorting lumber in medium and small sawmills. “Woodworking industry”, 5/2006 pp. 8-11) automated sorting line lumber containing a control panel, slide gates, remote sorting conveyors, divided by width by partitions into corridors, dumping devices, characterized in that the slanted gates are combined with a drive reversing with a fan, divided by partitions into corridors, they form a sorting table, which, by command from the control panel, provides the boards to the external sorting conveyors located on both sides of the sorting table, while the corridors of the external sorting conveyors are a continuation of the corridors of the sorting table (analogue-5), selected in as a prototype. According to the applicant, the closest technical solution for the combination of matching features and the technical result achieved is the automated line for sorting lumber, utility model patent No. 56358 (analogue-5), which is selected as a prototype. The disadvantage of this (prototype) technical solution is that each corridor of the sorting table provides sorting of lumber into two

drive. For example; four corridors - 8 drives (sorting fractionality 8). A technical solution is proposed for the line for sorting lumber, providing an increase in the fractionation of sorting due to one additional sorting corridor, not by 2, but by 4 units.

For example, adding four corridor lines to another fifth corridor, using the proposed technical solution, we get a sorting line with sorting fractionality 12, not 10, as would be the case with the prototype.

This is achieved by the fact that at the ends of both (one on each side of the sorting table), preferably the central remote sorting corridors, an additional section of the drive conveyor is installed with a two-sided dumping device of gravity or any other type.

The claimed technical solution is illustrated by the schemes: in Fig. 1, a schematic diagram of a sorting line, in Fig. 2 a cross section of a line along AA., In Fig. 3, a side view of an additional section of a drive conveyor, and in Fig. 4, a cross section of an additional section in BB .

Boards 1 per line are fed by a transverse conveyor 2.

The automated line consists of a control panel 3, a sorting table as part of a switchgear 4 with slide gate valves, a drive reversing conveyor 5, divided by the width of the walls 6 into corridors 7, and remote drive conveyors 8, separated along the width by the walls 9, forming corridors 10 for direction boards to the place of discharge into the drives 11 (12) and additional sections of the conveyor 13 with a bilateral discharge of lumber. Moreover, the corridors 10 of conveyors 8 are a continuation of the corridors 7 of the sorting table.

At the end of each corridor 10 there are shields 14 installed at an angle of more than 90 ° to the longitudinal axis of the conveyor, while on the rollers 15 of the remote conveyors 8 located in the places where the boards 1 are discharged into the drives 11, 12, screw winding is made. On the additional sections 13 there are spring-loaded stops 16 with microswitches 17 located at right angles to the longitudinal axis of the sections 17. The lumber is discharged from the additional sections by forcing the section to the opposite direction (gravity discharge), as shown in Fig. 4, or by any other way.

The drive of the conveyors of the additional sections 13 is preferable from the remote conveyors 8 through any transmission, their autonomous drive is not excluded.

Storage devices for boards can be in the form of templates 12 or receiving tables 11. In the first case, the formation of drying stacks or transport packages is assumed in a special automated packaging (stacking) device (not included in the line), - in the second 18 directly at the line.

Automated line works as follows:

The operator includes a transverse conveyor 2, right, left remote conveyors 8 and additional sections 13. On the feed conveyor 2, the boards 1 are located at the pushers and at regular intervals are fed to the sorting line, while the movement speeds of the feed 2 and sorting conveyors 5, 8 must to be synchronized.

The operator visually evaluates the board (its size, quality, grade, wood species), presses the corresponding button on the control panel 3, while the corresponding gate rises on the switchgear and the reversing conveyor 5 is turned on in the desired direction. The boards through the window of the raised gates fall into the corresponding corridor of the sorting table 5 and move with the rollers to the end of the corridor 8, where they abut against the shield 14 mounted at an angle, and by means of screw winding made on the rollers 15 are dumped into the drive 12 or onto the receiving table 11.

To address lumber to drives, additional sections require a more complex addressing system. One of the possible options may be a “pre-order” from the control panel with the actuation of the resetting devices from the end switch 17 when the end of the board hits the stop 16.

Further, with significant volumes of lumber production (30-40 thousand m ³ per year) and the presence of an automated device in the complete set of the sawmill for forming drying stacks (transport packages), a bundle of lumber from the template (drive 12) is transported by this truck to this device for drying stacks, and in the absence of such a stacking device, drying stacks 18 and transport packages are formed by two workers directly near the sorting line.

The technical result of the claimed technical solution is to simplify the design, reduce the metal consumption and manufacturing cost of the sorting line in terms of one sorting place (drive).

The claimed technical result is achieved: by installing at the ends of the central corridors of the external sorting conveyors sections of additional conveyors with two-sided discharge of lumber from them into drives.

Using the proposed technical solution, sorting lines with sorting fractionality from 8 to 20 can be manufactured.

The claimed technical solution can be implemented in industry using standard equipment, non-deficient materials and components in any domestic enterprises of timber industry engineering.

The analysis of the prior art according to the patent and scientific and technical literature of the claimed technical solution did not reveal a tool that has features identical to those contained in the claimed solution, which allows us to conclude that it meets the criterion of "novelty" presented to utility models. A comparative analysis of the claimed technical solution and prototype allowed us to establish the presence of significant distinguishing features, allowing to obtain the claimed technical result.
