Description

(54) DEVICE FOR SORTING logs

one

The invention relates to timber rafting and can be used to mechanize the sorting of logs on rafting raids.

A device for sorting logs is known, comprising a sorting corridor formed of sections consisting of parallelly arranged pontoons having sorting gates with log accelerators, pushers and a transverse conveyor 1.

A disadvantage of the known device is its unreliability in operation, since it is not possible to skip logs whose length is longer than the width of the passage of the section, which will cause jamming, breakage of the traverse, i.e. violation of the sorting process.

The purpose of the invention is to increase reliability.

The goal is achieved in that guiding devices pivotally attached to the pontoons of each section are oriented relative to the transverse conveyor by means of elastic elements located between the guiding devices and the pontoons.

FIG. 1 shows the sorting machine, plan; in fig. 2 - the moment of interaction of a long log with a guide device when it is transferred to the sorting section of another shorter size group of logs.

Sorting machine consists of sorting corridor 1, formed from sections 2, transverse bridges 3, control system of the control panel (not shown in the drawing).

Each section 2 is made the same width, which provides the movement of logs of maximum length, and consists of two

10 parallel-arranged pontoons 4 having a sorting gate 5 with accelerators of 6 logs, pushers of 7 logs located on both sides of the section in front of the sorting gate, a transverse conveyor 8.

Sites for sorting logs of various lengths may contain one or more sections. It depends on the fractionality of sorting by assortment. To the pontoons at the exit end of each section, connected to the section of the next sorting section of a different size group of logs, guiding devices are hinged, made in this case in the form of shields 9. The shields 9 are oriented relative to the conveyor 8 with elastic elements 10 located between the shields 9 and pontoons 4.

The conveyor 8 is made in the form of two working branches 11, interconnected by cross-pieces 12, and is located at the level of the water horizon. Depending on the design of the pushers 7, the crosspiece 12 can be made at different sorting sites of the same or different lengths.

Sorting yards adjoining gate 5 are marked with position 13, and logs - 14.

Sorting logs is as follows.

The logs, 14, are put under the moving traverses 12 of the conveyor belt 8. The operator determines the grade of the log and pressing the appropriate button, orders the push of this log by a specific push rod 7. The latter is triggered at the specified location and pushes the log 14 into the gate 5. At the same time, the accelerator 6 outputs the log 14 from corridor 1 to the side yard 13.

In the first section, the longest logs are sorted. At the same time, shorter logs are moved by cross-pieces 12 of conveyor 8 to section 2 of the next sorting section.

The cross conveyor of this section captures the logs 14 by cross-pieces 12 and moves them further. Here again, the sorting of longer logs takes place, and the remaining logs arrive at the subsequent sorting section. This way logs of all lengths will be sorted.

At each section of sorting, shorter logs that cannot be sorted on this section can be displaced relative to the axis of the conveyor 8 as a result of exposure to external forces. In this position, the axes are moved by cross-pieces 12 inside this section. When switching to another sorting area, these logs interact with the shields 9. In this case, the logs to be sorted will be prepared for sorting in this area, i.e., the ends of the logs will be located in the area of the pushers 7 when they are further moved. impact on the logs by pushers 7, they are safely thrown into the side yards 13.

In the event that a long log has not received an order for ejection into the corresponding side yard, or the order has not been fulfilled, or has to be specifically passed to the end of the sorting bed, this

The log is traversed by 12 cross conveyors and is moved from the first section to the end section. At the same time, the log pushes the shields 9 to the pontoons 4. As soon as the log moves from this area, the shields 9 under the influence of the elements 10 return to the original position, oriented relative to the cross conveyor.

The use of the invention allows to increase the reliability of the sorting machine, since it is the implementation in this

The width of the sections of the same width, the presence of guiding devices oriented to the cross conveyor by elastic elements, ensure the free passage of long logs to the end of the sorting corridor, preserving after their passage

o Reliable grading of shorter logs. Owing to these same reasons, convenience is created when using a machine, since it is possible to sort logs of any length in any sections, besides using the proposed invention simplifies the joining of sections, increases maintainability, shortens the production time.
