Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for group and individual sawing of logs, comprising a machine for individual sawing and sorting, and the use thereof in storage for primary wood processing.

Fateev, -P. A. and -Briuhanov BA, Group sawing long timber in the plant "Krasnoyarsk" - "Lesnaya promishlenost", 1978, No. 4, pp. 15-16 is known a group sawing long timber, which includes a mobile crane, in whose opening a pole is attached. On the column are mounted chain cutting devices with the possibility of vertical movement as well as a platform moving on the rails. The platform is loaded with bundles of unsorted long wood. The machine is also equipped with a longitudinal sorting conveyor.

The disadvantage of this device is that the quality of the materials produced deteriorates due to - large differences - in the dimensional and quality parameters of the long wood to be cut and due to the execution of only non-specific group blanks. At the same time, the workload of loading and preparation is increasing several times because of the need to separate and sort the already cut material.

The Bulgarian author's certificate No. 34 649, IPC B 27 B 11/12 discloses a machine for individual sawing and sorting of logs, which comprises three consecutive tilting trucks, ie a sorting, working and transport truck, a hydraulic crane with a cab for the operator, who is standing on the work cart, as well as the cutting device and the longitudinal conveyor with the length measuring system, which is laterally adjusted on the three carts.

At this time, no device for group and individual cutting of logs is known.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for group and individual sawing of logs, with which a perfect utilization of the material is achieved.

Surrounding is solved by the introduction of the device according to the invention, which consists in that the machine is mounted laterally on its transport trolley block of cutting devices, in the immediate vicinity of which is a transverse conveyor with front support and separation stands, behind the front support is the hydraulic manipulator is fixed.

The advantages of the invention lie in the optimal utilization of the wood without its unnecessary consumption.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which FIG. 1 shows a top view of the device and FIG. 2 shows a side view of the device.

Apparatus for group and individual cutting of the timber consists of a machine for the cutting and sorting of individual timber, which contains three serially connected tipping truck 1 _{characterized} i.e. sorting, working and transport truck crane -hydraulický - '2 -s kabinwu pr®. - an operator who is standing on - a transport trolley 1, a cutting device 3 and a longitudinal conveyor 4 with a length measuring system - which is built laterally to the three trolleys 1. A block 5 of cutting devices is arranged laterally to the machine. . A transverse conveyor 6 is mounted in the immediate vicinity of the block 5 and is provided with a front support 7 and a separation 8.

Two separating stands -8 each form one cell. A hydraulic manipulator 9 is arranged behind the front support 7.

The technological process for the use of the device for group and individual cutting of the liquid is in the following order:

The operator takes the individual long woods from the stack unloaded on the platform 10 by means of a hydraulic manipulator 9 and divides them according to their dimensions and quality in the cells formed by the separating stands 8 on the cross conveyor 6.

Long woods - embedded in cells must - have flush fronts. For this purpose, they come into contact with the front support 7, which belongs to the cross conveyor 6 and represents a vertical surface. - Individual long - woods. - Because of their characteristics they are not suitable for arrangement -in the near four or five cells on the manipulator 9, they are deposited above on already filled cells or in separate cells. Under these conditions, the transverse conveyor 6 is set in motion. This lasts until the first loaded cell is as close as possible to the block 5 of the cutting devices. Thereafter, the operator takes over from the machine for - individual sawing and sorting with - by means of a - hydraulic crane 2 long - for individual sawing and sawing with the cutting device 3. Further, they are sorted according to their properties. When the processing of these long timber was finished, the machine moves along the rails so that the beer - drunk of the group cutter 5 - is at the length of the first searched for: The distance from the front support 7 is also determined. The distance to the nearest - cutting device of the block 5 - which can be displaced by means of hydro-cylinders is also determined, and in this way the lengths of the following product groups are determined. In this state, the feed from block 5 of the cutting devices is switched on and at the same time as many bundles of products as a large number of these cutting devices are produced. The bundles thus cut are folded by a hydraulic crane 2 behind the machine. If the long timber is longer, the machine moves again up to the distance determined by the length of the next assortment and up to the final cut of long timber. Thereafter, the transverse conveyor 6 moves in steps, i.e. until the next cell approaches a maximum of block 5 of the cutting devices, and work continues in the same working sequence.
