SU147039A1 - Automatic Timber Sorting Device - Google Patents

Description

A DEVICE FOR AUTOMATIC SORTING OF FORESTRY was created on September 17, 1960 for Ld 679915/26 to the Committee for Inventions and Discoveries

under the Council of Ministers of the USSR Published in the "Bulletin of inventions No. 9 for 1962

The known devices for automatic sorting of timber using sensors and relay follower channels have a low sorting accuracy, since the command to drop a log into a given cell is supplied from a common control panel beyond the actual position of the log on logs. To ensure the interval between the logs in the known devices, two conveyors with different speeds are used, which leads to unproductive power consumption and does not provide an exact interval of a given value.

The proposed device is characterized in that the sensors, which follow the rear end of the log and give the command to drop it at a given point of the dragging gage, are located along the conveyor. This will greatly improve the accuracy of sorting.

Another distinctive feature of the proposed device is the use of two conveyors, one of which, the remote one, stops at the moment when the distance between the ends of the logs is less than the specified one. This feature will allow with accuracy to ensure the specified intervals between logs and reduce power consumption.

The drawing shows a schematic diagram of the proposed device for the automatic sorting of timber.

The device contains two transnortera - remote / and working 2, moving the sorted logs 5. For normal operation of the device, the conveyors / and 2 should provide the necessary minimum MATERIALS

the interval between the ends of two moving logs, which should be equal to a given value of SQ. Near the conveyor there are cells into which logs are dumped, depending on their length. The cells are arranged in such a sequence that the log of the smallest length (/ i) is dropped into the first cell, and the log of the greatest length (2 ") into the latter. Thus, logs along the conveyor after their sorting are arranged in the following sequence ....

A. k, kIn, where / 1 / s / s /

The distance between any neighboring cells is chosen equal to a constant value of K, and the value of K. must be necessarily less than a specified distance of 5 ° between the logs, i.e. 5 ° / s.

Sensors are installed along the conveyor, which track the rear end of the log and give a command to drop it into a given cell depending on the actual length of the log and on its actual position on the log. To provide a predetermined interval of 5 ° between the logs, the same sensors are used which give the command to stop the remote conveyor / in the event that the actual distance between the logs is less than 5 °.

The device can be widely used in the woodworking industry to automate the process of sorting various types of timber.

Subject invention

Claims (2)

1. A device for automatic sorting of timber using sensors and relay tracking channels, characterized in that, in order to improve sorting accuracy, sensors following the rear end of the log and giving the command to drop it at a given breakpoint point are located along the conveyor belt. 2. The device according to claim 1, characterized in that, in order to ensure a given interval between the logs, two conveyors are used in it, one of which, the remote one, stops at the moment when the distance between the ends of the logs is less than the specified one.
