SU70469A1 - Sorting corridor for transverse log bristles - Google Patents

Description

The proposed sorting corridor for the transverse bristle of logs has the following arrangement.

From the main sorting corridor 1 (Fig. 1), through which the wood is fed by a transverse brush, logs with a difference in length of up to 1 l are selected to the side corridors 3 using drum accelerators 2.

A conical metal drum with spikes and driven by an electric motor is used as an accelerator.

The side sorting corridor has a stepped form in plan with decreasing corridor width in steps corresponding to the length of logs by up to 0.5 m. Thanks to this shape of the corridor, the logs are automatically sorted as they move along the corridor with a transverse brush.

Logs of the greatest length inevitably enter the first sorting yard; shorter logs are passed to the next courtyard, etc.

The automatic sorting of logs in a side step corridor is provided by a special sequential arrangement of drums

each sorting corridor. This is achieved by a device (Figs. 2 and 3) consisting of two drive cones provided with spikes 4 and 5.

One drum 4, having a length of 4 m, is installed under bridge 6 of the sorting gate and is driven by electric motor 7 by means of a chain transmission 8.

The second drum 5, having a length of 1 m, is installed under the bridge 9, which overlaps the sorting corridor at a distance of 1.2-1.5 m from the left side of the corridor and is driven from the first drum 4 by means of a gear train 70.

The first drum 4 rotates clockwise and guides the logs inside the sorting yard. The drum 5 rotates counterclockwise and guides the logs to the side of the corridor opposite to the gate of the sorting yard.

Logs moving along the side sorting corridor inevitably fall under the drum 5, by rotating which the chuck is automatically aligned along the side of the corridor opposite the gate of the courtyard. Due to this, it is excluded

the possibility of 4 logs under the drum having a length less than that which is selected in the courtyard. These smaller logs follow the corridor to the next sorting yard.

Subject invention

1. Sorting corridor for a transverse brush of logs along which drum boosters are installed, characterized in that for the purpose of automating the sorting of logs along the length of the boosters

installed in pairs and made rotating in opposite directions, the front ones being designed to align the ends of the bristles by pressing them against the walls of the corridor opposite the accelerators, and the rear ones to take the longest logs into the side corridors. 2. A corridor according to claim 1, characterized in that it has several consecutive pairs of drums installed for the purpose of sequential selection of logs of decreasing length.
