Description

The invention relates to the lumber industry and can be applied in units for rejection, trimming and sorting and packaging of sawn timber.

A known installation for rejecting, trimming, sorting and packing lumber, including a feeder, reject devices, trimming and palletizing units.

In order to increase plant productivity, improve the quality of rejection of sawn timber and improve the layout of equipment, the sawnwood feeder, rejection devices, trimming and sorting units are connected by one transverse conveyor, the rejection devices are made with a system of removable and attached levers for transferring sawn timber from the cross chain conveyor and are equipped with a feeder mi, and removable levers are made with a drive from a transverse chain transorter using a chain transmission; The sprocket is equipped with a cam interacting with a roller of a pivoting lever connected with the sector mounted on the shaft of the removable levers, and the lifting and lowering of the hinged levers are performed with the help of a cam mounted on the same shaft with an asterisk associated with the chain transmission with the transverse chain transporter.

FIG. 1 shows the proposed installation, the general view; in fig. 2 - rejection device, side view; in fig. 3 - the same, top view.

The installation includes a feeder containing a chain conveyor 1, an elevator 2, a removable conveyor 3, a cumulative conveyor 4, a conveyor 5 for removing gaskets, a piece delivery mechanism 6, a delivery delay mechanism 7 made in the form of several pneumatic cylinders, reject devices 8, 9, 10 and 11, containing removable levers 12, drives 13, tilters 14, pivoting stops 15 and 16, roller conveyors

17, hinged levers 18, bridge 19, mirror 20, transverse chain conveyor 21, the movement of the chains of which is transmitted through chain transmission 22, 23, 24, cam 25 sitting on the shaft 26 of the driven sprocket, lever 27 with roller

28, t gu 29, sector 30, with removable levers 12 mounted on one shaft 31 with sector 30, sensors 32 located on hinged levers 18, with which cam 33 transmits movement of the conveyor chain 21 by

chain transfer 34, stops 35 of the conveyor 21, removing the board from the levers 18, face-aligning roller conveyor 36, slasher saw 37, trimmer 38, conveyor 39 for waste, sorting unit containing chain conveyors 40, 41, 42 and 43, sorting chambers 44, paring machine 45 and sensor 46 sizes of lumber.

The installation works as follows.

The lumber package is installed on the transverse conveyor I. The removable conveyor 3 transfers the upper row of boards to the accumulative conveyor 4, the gaskets are fed to the conveyor 5. The single-feed mechanism 6 loads the boards onto the stops of the upper branch of the transverse chain conveyor 21. After aligning the ends with a roller table 36, the ends of the boards cleaned with a saw 37, Removable levers 12 remove the boards from the transport 21 and stack 13 reject devices 8-11 in the drives. The clerk, located on bridge 19, inspects the leading edge and upper face of the first board, which is located in drive 13, with tilter 14, shifts it onto the roller conveyor 17 and inspects the second face and edge. With the help of mirror 20, the refiner assesses the quality of stripping of the butt and, if necessary, re-facing, shifts the board to the left with a roller conveyor 17. Then, the decoiler sets the command to turn on the trimmer saw

38.According to the sort team, the stops 15 and 16 are rotated and the board slides onto the hinged levers 18. The board on the hinged levers 18 is controlled by the sensor 32. The board is removed from the levers 18 by the stops 35 of the chain 21. The detached boards enter the conveyor 40, and the lengths fall onto the conveyor

39. Taking into account the team of the grade specified by the reaver, and the length measured by the sensor 46, the boards are transferred to the appropriate sorting chambers 44 with the help of an accelerator conveyor 41 and the lower branch of the conveyor 21.

The bundles of boards from the sorting pockets fall onto the conveyor 42 and are directed to the bagger 45, where dense transport packages are formed.

The setup can work in hard, combined and free rhythms.
