Abstract

The invention relates to the timber and woodworking industry and mb, used on longitudinal sorting conveyors. The purpose of the invention is to increase the reliability and durability of the structure. A shaft (c) 1 is installed on bars x 3 racks under the bearing branch of the traction unit 2. Bearings 12 V 1 are connected to the drive 11 via a cam-type electric drive. The disk 15 interacting with sensors (D) of the angle of rotation and D 17 fixing the position of B 1 through the brake 7 turning B 1. The electric coupling 12, brake 7, D turning angle and D 17 are equipped with an electric blocking 18. B 1 is rigidly mounted pushers in the form of levers 6. On the side of movement of the logs, the levers 6 have springs (P) 8. The working surface of the latter is made curved with radial 9 and an angular 10 clearances relative to the lever 6. When the electrofusion 12 is turned on, the brake 7 is lowered and В 1 with levers 6 and Р 8 begins to rotate in a given direction of the scientific research institute. This provides a contact P 8 with the log. In the extreme position P 8, the log is dropped into the accumulator and, according to the signal D of the angle of rotation, the actuator 11 is turned off. 3 il. to (L

The invention relates to the timber and woodworking industry and can be used on longitudinal sorting conveyors for dumping logs into drives.

The aim of the invention is to increase the reliability and durability of the structure,

FIG. 1 shows schematically the proposed diverter; the general view in FIG. 2 - end view; FIG. 3 shows the sensors for the electrical control of the ejector.

The resetter contains a shaft 1 mounted in bearings 2, which are fixed to bars x 3 racks 4 under the carrying branch of the traction member 5. On the shaft 1, the pushers are rigidly fixed in the form of two levers 6, one of which is equipped with an electric brake

7. On levers 6 fixed springs

8, the working surface of which is curved with radial

9 and 10 angular clearances between the springs 8 and the levers 6. The shaft 1 rotates from the actuator 11 through a cam electrofusion 12, equipped with a spring 13 and an electric actuator 14. The specified angle of rotation of the shaft 1 is controlled by a disk 15 fixed on the shaft 1 and interacting with the angle sensors 16 and the sensor 17 for fixing the initial position of the shaft 1 through the brake 7, the electrofusion 12, the brake 7 and the sensors 16 and 17 are provided with an electrical interlock 18.

The dumper works as follows.

To reset a log 19 from a traction device 5 to one of the sides of the conveyor, a corresponding signal is fed to the drive 11 via the electric drive 14.

coupling 12, which is engaged, overcome; Its curvilinear working surface resistance of the spring 13. The brake 7 is lowered, and the shaft 1 with the levers 6 and the springs 8 begins to rotate in a given direction, ensuring the contact of the curvilinear surface of the springs 8 with the object to be reset. Since the springs 8 are equipped with radial 9 and 10 angular gaps, dos

the spring contact of the springs 8 with the object to be dumped due to the radial clearance, and the angular clearance allows to damp the axial loads of the moving object.

As soon as the spring 8 reaches the extreme position, the log 19 is dropped into the accumulator, and the sensor 16 sends a signal to turn off the drive 11, remove the signal from the electric coupling 12. The drive 11 turns off and continues to rotate by inertia, and the shaft 1 with the springs 8 starts rotating in the opposite direction , try to take a stable position. When the potential rotational energy of the shaft 1 is zero, the disk 15 acts on the sensor 17 and applies the brake 7 through the electric blocking system 18. The shaft 1 with the springs 8 is fixed in the initial position. The dumper is ready for the operation to reset the next object to either side of the conveyor.

The cycle is repeated.
