(5t) METHOD FOR CLOTHING

one

The invention relates to the sawmill and woodworking industry and can be used to cut logs into logs.

The known method of cutting the whips, including the cross feed of the whip, trimming its tops and com, sawing for assortments and removal of the obtained assortments 1.

The disadvantage of this method is the low yield of industrial wood. This is due to the lack of visual assessment by the operator of the ends of the logs.

The purpose of the invention is to increase the volume output of wood.

The goal is achieved in that according to the method of cutting the whips, the cutting of the whip is carried out by means of doubled saws, and the assortments obtained after sawing the whip with the saws of the first row are fed with an offset in the feed direction OD14N relative to the other to the saws of the second.

In addition, the supply of assortments to second-row saws is carried out at a faster rate than that of the first row, and the supply of assortments to second-order saws begin at different times.

FIG. 1 shows the device, the general view (in plan); in fig. 2 shows section A-A in FIG. one.

The device contains end face equalizer in the form of augers 1, a cross conveyor 2 with a drive 3, butt and vertex saws Ts. with drives 5 cutting saws of the first variety and 6 drives with 7 adjusting saws of the first variety 6 with drives 7. cutting saws of the second design yes 8 with drives (not shown).

Claims (2)

The face-leveling augers 1 comprise a helical groove 9, a drive 10 and a chain transmission 11. The transverse conveyor 2 consists of a welded frame 12 on which a drive shaft line 13 is mounted, consisting of shafts CO with sprockets 17 and bearing supports 18 and chain gears 19, connected kinematically between themselves shafts It-lS. In addition, tensioning stations 20 and traction units 21 with stops 22 are mounted on the frame for moving timber along the conveyor. The cross conveyor 2 is divided into two drive sections 23 and 24. Komleva and apex saw 4 and cutting saws of the first row 6 are stationary, and cutting saws of the second row 8 are installed on the swivel beam rocker arms 25, operated by the operator. Moreover, the drive section 24, which has an increased speed due to the chain transmission 19, is placed after the first row of saws and consists of three parts that are displaced relative to each other in the direction, which allows the middle assortment after cutting it from the whip to move along the conveyor 2 with respect to to extreme assortments. The method of cutting the logs is carried out as follows. The whips intended for cutting are fed to the end-leveling augers 1, which align the ends and transport them to the cross conveyor 2 of the cutting device. The stops 22, which are located on the pull-out organs 21 of the drive section 23 of the cross conveyor 2, whip under the grab and are fed to the butt and apex saw 4, where it is edged, then fed to the cutting saws of the first row and cut into three pieces. After passing through the first-grade assortments, the middle assortment immediately goes to the drive section 24, which has an increased speed. Extreme assortment falls on section 24 after a certain period of time. As a result, the average assortment moves ahead with respect to the extreme ones and the operator can assess the quality of the assortments according to the condition of their ends. If the operator notices rot or other defects in some assortments, he raises the corresponding cutting saws of the second row and cuts this assortment into two parts. If the defect affects no more than 1/2 of the assortment, then the other part can go to the business wood. As a result of providing such a visual rate by the operator of the condition of the cut logs, the yield of industrial wood increases. Claim 1. A method of cutting logs containing a cross feed of a whip, cutting its top and com, sawing into assortments and withdrawing the obtained assortments, characterized in that, in order to increase the volume output of wood, the whip is opened by means of two Yes, saws, and assortments obtained after sawing the whip with the saws of the first row, are fed with an offset in the feed direction one relative to the other for saws of the second row. 2. A method according to claim 1, characterized in that the supply of the assortments to the second-row saws is carried out at a higher speed than on the saws of the first row, and the supply of the assortments to the second-row saws starts at a different howl.
