Description

one

The invention relates to the sawmill industry and may be intended for sorting sawn timber in a sawmill workshop.

A device for sorting sawn timber is known, which includes a sorting conveyor with stops, a piece feed mechanism, sorting compartments and a remote conveyor.

In order to improve the performance of the device in operation, the latter is equipped with a lumber transfer mechanism from the upper branch of the sorting conveyor under the stops of the lower branch, and a piece feed mechanism is installed above its upper branch, made in the form of driven screw roller tables with L-shaped hinges attached to them, The mechanism for transferring lumber from the upper branch of the sorting conveyor to the stops of the pizhnyy branch is made in the form of a growing cross and a conveyor with stops.

FIG. 1 schematically shows the proposed device, a general view; in fig. 2 - the same plan view; in fig. 3 shows the node I in FIG. one; in fig. 4 - node And in FIG. one.

The device includes a sorting conveyor 1 with stops, above the upper branch of which there is a piece feed mechanism consisting of a roller table with screw po2

faces 2 and L-shaped levers 3 sharpened on the frame of the roller table, the mechanism for transferring lumber from the upper branch of the sorting conveyor 1 to the stops of the lower branch, consisting of a rotating cross 4, connected by a chain drive and an elliptical asterisk 5 with conveyor 6 with stops, driven by the sorting conveyor 1, the sorting compartments 7 with the pliers 8, the guides 9 for boards, the external conveyor 10.

The device works following1OP1, it () sconce: and) m. Boards from sawmill shop machines postunay on live rolls with screw rollers 2

and using L-shaped levers 3 are loaded one for each row of stops of the sorting conveyor 1. A moving row of stops of the upper branch of the sorting conveyor 1 removes the board from the shelves by lever 3

and moves it towards the lumber transfer mechanism from the upper branch of the sorting conveyor under the stops of the lower branch. In the case when the previous stops of the chains are occupied by boards dropped from

others ahead of the live rolls, these

boards on their way raise the L-shaped levers 3 and do not allow them to grab the board,

lying on these levers. With further

the movement of the board, moved by the stops of the upper branch of the conveyor 1, is applied to the lever

crosses 4, which rotates at an angle of 90 ° and lays the board on the conveyor 6, which feeds it under the stops of the lower branch of the conveyor 1. When the board approaches the specified sorting compartment 7, a command is given to reset it, the gate 8 is lifted, and the board is dropped. After accumulating the required number of planks in the compartment, the plank opens and the planks fall onto the external conveyor 11, from which they come to the devices for forming the package.
