Description

The utility model relates to the production of lumber from wood by sawing and can be used in the manufacture of edged boards, beams, blanks for various types of molded products, by cutting logs in stationary or field conditions.

Known log saw machine in which the sawing of logs is performed by a single-disk saw unit using the mechanism of automatic rotation of the saw unit [].

Single-disc radial saw machines are also known: for example, a single-disc angular sawmill WoodVER УДП-550 [] or a single-disc angle saw UP-700 StrojCAD [].

In known machines, the bed consists of several rectangular sections along which the saw carriage moves. During the sawing process, the log is mounted on the bed and fixed with screw clamps (scissors). At the beginning of cutting, the saw blade is in a horizontal position. As the working stroke is advanced, the saw unit moves along the center axis of the log, making a horizontal cut of the log along its entire length.

After the log has passed, the saw unit automatically rotates 90 ° and secures in a vertical position. As the working stroke is performed in the reverse position, the log is cut vertically, also along its entire length, i.e. the incised part of the log is sawn off.

The main disadvantage of the known single-disk log saws is the loss of time to turn the saw blade, which reduces productivity.

Also known are machines with two circular saws located in horizontal and vertical planes, for example, the Bars-3 corner automatic sawing machine [].

During the operation of the machine, the log is mounted on a sectional rectangular fixed bed of the machine using hydraulic mechanisms. The bed is equipped with guides along which the carriage moves. The feed rate to the cut is automatically selected depending on the load on the saw blade motors. The disks are moved to a predetermined size under the control of a special program, which, based on the actual log parameters, calculates the optimal cutting map.

A disadvantage of the design of the known machine is that when replacing a vertical saw, it is necessary to move the electric motor and spindle, as a result of which the operation of setting up a vertical saw takes a lot of time.

Closest to the claimed log saw is a prototype log saw containing a bed with rail tracks, on which an electric drive carriage equipped with a control panel is mounted, on which a single-disk unit for vertical sawing and a single-disk unit for horizontal sawing of logs are mounted on a rotary bracket , as well as a log fixing mechanism installed on the bed [patent for utility model of the Russian Federation No. 115286, IPC B27B 7/00, application No. 2011142839/13 of 10.25.2011].

The main disadvantage of the known machine is its low productivity due to the fact that vertical sawing is carried out by one circular saw, as a result of which several cuts of the carriage with saw aggregates along the log are required for cutting the log into bars or boards. Another disadvantage of the known machine is the high complexity of performing auxiliary operations: loading, fixing, tilting logs, unloading the resulting lumber, adjusting the vertical depth and horizontal sawing height.

The objective of the utility model is to eliminate these drawbacks.

This goal is achieved by the fact that in a log saw containing a frame with rail tracks, on which an electric drive carriage equipped with a control panel is installed, on which are located a vertical sawing unit and a horizontal sawing unit, according to a utility model, the vertical sawing unit is multi-disc, and the horizontal units and vertical sawing equipped with servo vertical movement associated with the control panel.

To enable adjustable positioning relative to the log, the multi-disc unit of vertical sawing is equipped with a servo-drive of horizontal movement along the axis of rotation of circular saws.

At the same time, the unit for horizontal sawing of logs can be made in the form of two circular saws lying in the same plane, or in the form of a band saw.

To reduce the complexity of cutting, the machine is equipped with electric drive mechanisms for loading, tilting and fixing logs, as well as an electric drive mechanism for unloading the resulting lumber.

To improve working conditions, the machine can be equipped with a chip removal conveyor or a vacuum cleaner.

To increase the degree of automation, the remote control is made with numerical program control of all electric drive units and machine mechanisms.

A comparative analysis of the inventive log saw machine with a prototype and with other solutions in the art shows that the set of features set forth in the patent formula is unknown from the existing level of technology, on the basis of which we can conclude that it meets the criterion of the useful model of "novelty".

The compliance of the proposed solution with the criterion of "industrial applicability" can be seen from the following example of a specific implementation of a log saw.

The utility model is illustrated in schematic drawings:

Figure 1 is a General top view of a log saw with a horizontal sawing unit in the form of two circular saws;

Figure 2 is the same with the horizontal sawing unit in the form of a band saw;

Figure 3 is a General front view of a log saw.

The list of symbols in the drawings:

1 - bed;

2 - rail track;

3 - carriage;

4 - multi-disc unit vertical sawing;

5 - horizontal sawing unit;

6 - control panel of electric drive units and machine mechanisms;

7 - sawn log;

8 - circular saw;

9 - a band saw.

The log saw machine comprises a frame 1 with rail tracks 2 on which an electric drive carriage 3 is mounted. On the electric drive carriage 3 with the possibility of vertical movement from servo drives (not shown) are a multi-disc unit 4 vertical sawing and unit 5 horizontal sawing.

While the unit 4 vertical sawing is equipped with a servo horizontal movement along the axis of rotation of circular saws (not shown).

A log saw machine can be equipped with electric drive mechanisms for loading, tilting and fixing logs, an electric drive mechanism for unloading the resulting lumber, as well as a chip removal conveyor or vacuum cleaner (not shown).

The machine is equipped with a remote control 6 with numerical control of all electric drive units and mechanisms.

The horizontal sawing unit 5 can be made in the form of two circular saws 8 lying in the same plane (Fig. 1) or in the form of a band saw 9 (Fig. 2).

The operation of the log saw machine is as follows.

Timber (log 7) is supplied from the drive (not shown) to the surface of the bed 1. Next, the log 7 is fixed on the bed 1 using electric radial or end clamps (pins) - not shown. By the combined actions of the servomotors (not shown) of the vertical movement of the units 4, 5 and the servomotor (not shown) of the horizontal movement of the unit 4 of vertical sawing, controlled by the panel 6, the necessary horizontal height and depth of vertical sawing of the log 7 are set, and the positioning of the aggregate 4 relative to the log 7 is also ensured in the horizontal plane. After that, from the remote control 6, control signals are sent to turn on the electric drive (not shown) to move the carriage 3 along the rail 2 and turn on the electric motors (not shown) of the saw units 4, 5.

According to a given program, the saw units 4, 5 carry out the cutting of the log 7 into the necessary lumber (for example, slabs, boards, boards), removed from the frame 1 using an electrically controlled unloading mechanism (not shown).

The distance between the saw planes of the multi-disc unit 4 vertical sawing is chosen in accordance with the most economical use of the workpiece (log 7) when receiving lumber of a given nomenclature.

The technical result from using the utility model is to increase productivity due to multi-disc vertical sawing of logs, as well as reducing the complexity of performing auxiliary operations (loading, fixing, tilting logs, unloading the resulting lumber, adjusting the vertical depth and height of horizontal sawing).
