The invention relates to timber cutting and can be used in forestry, pulp and paper, and woodworking enterprises.

A device for group cutting of timber products is known, which includes receiving pockets, jaw grip, sawing body 13.

The drawback of the device is the absence of mechanisms for the sample delivery of CONDITIONAL assortments and harvesting of substandard assortments and wastes.

Also known is a unit for bursting out timber, including a receiving tray, maxillary. grip with opening jaws for receiving and unloading sawed-off assortments, a sawing organ, single-piece devices with chippers conveyor of low-quality assortments and waste 2l.

However, the design of the device provides for the movement of sawn-off assortments by means of an unloading mechanism to single-piece devices located at some distance from the sawing organ. At the same time, the jaws of the unloading mechanism are closed, moved to the initial position, fixation in the sawing area and the longitudinal supply of the pack is performed sequentially the next time, which reduces productivity, while the conveyor of non-conforming waste is located perpendicular to the longitudinal axis of the installation, therefore the pieces must be turned to 90 °, which leads to congestion and their osteopathy and, ultimately, to a decrease in the productivity of the installation.

The aim of the invention is to increase the productivity of the unit. I

This goal is achieved by the fact that. a unit for pachkovoy discloses chewy timber, comprising receiving tray, grapple with raskryvayuschimis the gums E for receiving and discharging offcuts assortments, the saw body, the piece vdachi device impingement, conveyor substandard assortments and waste grapple pivotally mounted directly above devices the piece of issue and made with the possibility of turning 583472.

the company of each jaw is separate, with the upper part of the grip in the closed position having a section corresponding to the profile of the receiving tray 5, and the lower part is made in the form of levers having slopes. the direction of the bumpers of single-item dispensers and mutually intersecting each other, while the trans-rater of substandard assortments and waste is mounted coaxially with the longitudinal axis of the unit between the single-item dispensers.

FIG. 1 shows a cutting unit assembly, general view; in fig. 2 the same, the view from the end.

The cutting machine includes a receiving tray 1, a sawing body 2, moving along the guideway 3, 0, the maxillary grip 4 for receiving and unloading sawn wood sorts, having inclined in the lower part, levers 5, hingedly mounted on the axis 6 fixed on support 7, hydraulic cylinders 8, devices 9 of the slurry with bumpers 10, conveyor 11 and for removal of off-market assortments and waste and sorting conveyors 12.

The unit works as follows.

The pack 13 of the whips is loaded into the receiving tray 1 and moves under the saw body 2, the hydraulic cylinders 8 and the jaws of the gripper 4 turn on, rotate around the axis 6, clamp the pack, then the saw organ 2 is turned on, which, moving along the guide 3, performs trimming packs. After the cutting is completed, the sawing member leaves the guide 3 and idles. Simultaneously with the idling of the saw organ 2, the hydraulic cylinders 8 and the jaws of the gripper 4 are simultaneously opened and the non-standard assortments are unloaded onto the conveyor 11, which is made coaxially with the gripper, therefore, the sorpentry, without turning, moves to the storage location or

recycling that eliminates congestion

% and their boning

After trimming, the stack of timber is fed to a predetermined length, at the same time squeezing the jaws of the gripper 4. Then another cut is made, after which, simultaneously with the idle stroke of the sawing organ 2, the logs are unloaded.

At the same time, depending on the quality of the assortments, one of the jaws of the gripper opens and they roll down the inclined lines 5 of the gripper 4 behind the bump stop 10 of the device 9 of the single piece, which feeds them further to the sorting conveyor 12. In this case, by separating the streams, the preliminary sorting assortments by breeds, sizes.

After unloading, a command is given to close the upper jaw of the jaw.

This 4 and at the same time, due to the fact that the cross section of the maxillary grip in the upper part corresponds to the tray profile, a command is sent for 5 longitudinal movement of the pack to the next cut. The cycle is repeated.

The unit allows you to reduce the production cycle, eliminate costs and bonfire substandard

assortments and, consequently, increase productivity in bursting of timber logs.
