Abstract

SUMMARY OF THE INVENTION: Traverse body 2 for timber materials is mounted on the traction device 1. The frame 3 is equipped with a rotary table 7 with hinged one ends on both sides of its longitudinal axis with rods 9. On the frame 3, an actuator 14 is mounted with a crank 13 for rotating the table 7. On the frame 3 the double shoulder arms are pivotally mounted for rotation in a vertical plane 10.11. The levers 10 have stops Ј 2 and are pivotally connected by one ends with the rods 9. The levers 11 are mounted on the free ends of the levers 10 by the middle part with the possibility of the ends interacting with the stops 12 and the crank 13. 7 Il.

Description

The invention can be used in the timber and woodworking industry when sorting round timber

Devices for dumping timber are known, including rotary horizontal axes installed under the longitudinal conveyor, rollers and drives with a WIDTHING mechanism.

The disadvantage of these devices is the cumbersome nature of their structures and the complexity of assembling the support.

A device for moving and double-sided dropping of round timber is known, which has a traction body with cross-arms and a resetter made in the form of mounted on the basis of racks mounted on the uprights of the turntable and the drive with a crank.

connected to the turntable through a kinematic connection, made in the form of rods suspended on the turntable by means of hinges of rods located on both sides of the longitudinal axis of the turntable of the plane of rotation of the crank. The hinge axes are parallel to the longitudinal axis of the turntable.

However, when this device is in operation, after a reset of the next timber, the rods oscillate by inertia, as a result of which the next cycle will be only with a complete attenuation of the oscillations of the rods, i.e. cycle time increases.

The purpose of the invention is to increase reliability and performance

Fig 2 shows the device at the moment of idling of the double-arm lever: not Fig 3 shows the device in its initial position, Fig 4 shows the device when the demand for timber is to the left: Fig 5 shows the device for resetting the timber to the right, fig. 6 - view of the double-arm; Fig, 7 is a top view of the two-arm lever

The device consists of a traction body 1 with cross-pieces 2 and a frame 3, which in cross-section is made in the form of an isosceles trapezium, the center of which coincides with the axis of the traction body.

On the frame 3 by means of the pivoting levers 4 and the hinges 5 and 6 a rotary table 7 is installed, on which with the help of the hinges 8 on one side of its longitudinal axis are fixed with the ends of the rod 9. The second ends of the rod 9 are pivotally connected the first two shoulders levers 10, which are doubled with the second two shoulders lever 11 and are designed to rotate in a vertical plane. The levers 10 are provided with stops 12 and are hingedly mounted with their middle parts on the sides of the frame 3.

The free ends of the double-arm levers 10 are pivotally connected to the middle parts of the double-arm levers 11, which are located in the plane of rotation of the crank 13 and can be cooperated by one arm with the stops 12, the other with the crank 13 connected to the drive 14.

The device works as follows.

The round timber on traverses 2 is supplied by a traction device 1 to a double-sided dumper. When timber is required to be dumped to one of the sides, the drive 14 is turned on. The drive 14, rotating the crank 13, engages it in engagement with the shoulders of the two shoulders 11, Continuing the rotation, the crank 13 deflects the levers 10 and 11, which raise the bar 9 together with the edge of the turntable 7, produced dropping timber. Upon further rotation of the crank 13, the lever 11 is deflected at the hinge in the direction of rotation of the crank. Crank 13 returns to its original position. In this case, the rotary table 7 of the rod 9 returns to its initial position under the action of the force of gravity.
