Abstract

The invention relates to the timber and woodworking industry and allows for improved reliability. The device comprises a frame 1 rotatable in the direction transverse to the direction of movement of the conveyor with bearing rollers 2 for a load-carrying body in the form of a belt 3 and a shank 4 and a device for turning and fixing the frame 1. The latter is made in the form of a single turn actuator fixedly mounted on its output shaft 5 of the rocker arm ( K) 6, fixedly mounted rails 11, slider (P) 9 installed in them and electromechanical clamp 11. The latter holds P 9 in the initial position of frame 1. At one end of K 6 there are two spring-loaded protections 7, between which the shank 4 is located in the initial position of the frame 1. The other end of the K 6 is connected to the P 9 through the connecting rod 8. The shaft 5 is connected to the shank 4 via the return spring 12. As the timber approaches the drop point, the drive is activated and retracted latch 11. When turning K 6, one latch 7 acts on shank 4 and tilts frame 1. With further rotation of shaft 5, the other end K 6 hits the shank, giving it an additional force impulse. The frame 1 is rotated 45 ° and the timber is dropped from the belt 3. The frame 1 under the weight of the belt and the spring 12 returns to its original position, and the P 9 in the lower position is locked with a latch 11. 2 Il.

Description

The invention relates to the complex mechanization of warehouse operations in the forest and woodworking industry and can be used in lower warehouses, exchanges of raw materials and woodworking enterprises.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows the device in the initial position of the swinging frame, cross section; in fig. 2 - the same, the initial moment of tilt of the swinging frame.

The device for two-sided dumping of timber from the conveyor consists of a pivoting frame 1 with bearing rollers 2 mounted on the sides of the frame with a certain pitch. The rollers 2 move the carrying element of the conveyor in the form of a conveyor belt 3. The frame has a shank 4 and can be rotated to both sides of the vertical axis through an angle of up to 45 °. A device for turning and locking the rotary we are made in the form of a mounted single turn motor (not shown), on the output shaft 5 of which the yoke 6 is fixed, the upper end of which is equipped with two spring-loaded latches 7. The latter can move in the rocker arm slots 6. 7 has a bevel, affecting which, the shank 4, when returning the frame 1 to its initial position, depresses the latch 7. In addition, the device for turning and fixing the frame 1 includes a hinge connected to the end of the rocker arm 6 by means of the connecting rod 8, the slider 9, which, during the reset cycle, moves in the vertical guides 10 from the lower end position to the upper position and holds it in the lower end position, which corresponds to the initial position of the frame 1, the electromechanical latch 11. The last one is locked with one company driven. The end of the shank 4 and the drive shaft 5 are connected by a return spring 12.

The device works as follows.

Timber on the conveyor moves along the sorting front. When approaching the dumping site (the timber is at the same time on the pivoting frame), a command is given to reset to one side or the other. The direction of reset is determined by the direction of rotation of the drive.

When a reset signal is given, the latch 11 is activated (retracted) and the beam 6 starts to turn in the required direction. One of the latches 7 its

the inner side acts on the shank 4, the inclination of the frame 1. In this case, the slider 9 moves to the extreme upper position, keeping the latch 11 in the depressed, retracted state during the entire reset cycle.

Upon further rotation, the other, lower end of the rocker arm 6 hits the shank 4, giving it an additional force impulse. After that, frame 1 continues to tilt up to 45 °, timber under the action of gravitational forces rolls in the transverse direction and falls into the hopper, and frame 1 under the action of elasticity of the tape and the return spring 12

returns to the starting position. The yoke 6, making a complete rotation, returns to its original position, with the slider 9, coming to the lowest position (its speed is 0), stops with the latch 11. Shank 4, approach

° to the rocker 6, squeezes one of the latches 7, overcoming the force of its spring, and takes a position between the latches 7. Guaranteed health between the latches and the shank ensures reliable operation

5 total device. After returning the frame 1 to its original position, the device is ready for a new reset cycle.
