(5) LENGTH DIMENSIONAL MATERIALS WITH ROLGANG

The invention relates to devices providing the discharge, transfer of lengthy materials from a roller table, for example, logs, to associated receiving devices (cross conveyors, slides, storage platforms, etc.), and can be used in the woodworking industry, in mechanisms loading lesorami, milling machine sawing and milling-cannoning machines, debarking machines, etc. A device for resetting logs is known, which includes a reset mechanism in the form of levers mounted on a common rotary horizontal shaft and attached to them an articulated pusher, an electromechanical drive connected to the shaft of the levers by means of a crank mechanism. When working, the pushers make a reciprocating movement and during the working stroke push the logs from the conveyor 1. The disadvantages of this device are the unreliability of the structure due to the occurring shocks at the time of the meeting of the pushers with the log; the impossibility of embedding it in a line in cases where the dumping of logs from the conveyor to both sides is required. The closest technical solution is a long-length materials ejector from a roller table, including ejection levers and at .. However, this device is not reliable enough in operation. The aim of the invention is to increase its reliability in operation. This goal is achieved by the fact that the drive is made in the form of a drive shaft with eccentrics and a roller fixed on each lever mounted with the possibility of interaction with the corresponding eccentric.

In the drawing is shown a diverter of lengthy materials with roller, ha.,. .

The longitudinal release device from the roller table includes ejecting levers 1 installed between the rollers 2 of the roller table and having the ability to rotate around the axes 3- The levers 1 have rollers k fixed, which are constantly supported on the working surfaces of eccentrics 5. These supports 7 together with eccentrics. The drive of the roller table is filled in the form of a shaft 6 with eccentrics 5, connected, for example, with an electric motor 8 and a worm gearbox 9, with the corresponding roller k interacting with each eccentric. The reset device has a locking device made, for example, in the form of a down switch 10 and a control lobe 11 attached -to the shaft.

The dumper works as follows.

When the electric motor 8 is switched on, the worm gearbox 9 transfers the rotation to the shaft 6 and the eccentrics 5 attached to it. “When the eccentrics B interact with rollers of the latter. The rolls roll over the working surfaces of the eccentrics, and there is a smooth rise of the levers 1 with the log, which rolls down.

on the working surface: {mchagov, for example, on the cross conveyor mated with the dumper. After making a full rotation of the shaft 6

levers 1 are lowered to the initial position. Drive dumper; using a locking device is turned off. The cycle is repeated.

Cam mechanism application

provides a smooth reset of the log, favorable conditions for the operation of the drive and the whole mechanism as a whole.
