Description

eleven

The invention relates to a cutting technique and can be used in the timber and woodworking industry in bursting and growing round timber.

FIG. 1 shows a general view of the device; in fig. 2 - the same, top view; in fig. 3 - chain conveyor shaft; Fig 4. - alignment of the ends.

The device for the opening of packs of logs contains a chain saw setting 1 with a 2-rotation drive and 3 driving over the saw chain, a tray 4 with a turntable 5, the working plane 6 of which is radially 7. The platform 5 is mounted on the shaft 8 of the chain conveyor 9 and is equipped with rigid stops 10 and bearings 11, the facing shield 12 and tra Versa 13 are fixed on the chains of the conveyor 14.

The device also includes sprockets 15 and cam clutches 16 with mechanism 2 (coupling clutch 17 17 interlocked with drive 18 through sensor 16 deflection clutch 16 and sensor 20 with stops 21 and 22 controlling the angle of rotation of the platform, limiter 23 and receiving device 24.

The device works as follows.

Before loading into tray 4, the device is reset. Shield 12 with the help of the actuator 18 is moved to the extreme position up to the stops 10. A stack of timber 25 is oriented with the ends of the shield 12 and loaded onto the platform 5, ensuring contact

plane 26 of the center of gravity of the pack with the working plane 6 of the platform 5, and informing it of longitudinal movement towards the shield 12 due to the chain 5 of the conveyor 14. The shield 12 acts on the sensor 19 and through the mechanism 17 turns on 16. The shaft 8 is jammed and the platform 5 starts to rotate together with the pack 25 until the stop 10 21, acting on the sensor 20, switches the actuator 18 to reverse. The pack end aligns. The limiter 23 thus eliminates tipping packs.

15 After aligning the ends, the platform 5 rotates to its original position, the abutment 22 acts on the sensor 20, disconnects the sleeves 16 and the bundle is lowered onto the yoke 13, takes the 20th horizontal position, and moves for a given length along with the shield 12.

After filing a pack for a predetermined length, the drive 18 of the longitudinal feed 25 is turned off and the drive 2 is turned on. After the cut is completed, the drive 3 is reversed, the chain is moved back to its initial position, and the assortments are fed by the receiving device 24 for the next operation. The actuator 18 is turned on, and the next cut is fed to the next cut. JJ After the last cut, the drive 18 is reversed and the shield 12 is reset to the starting position of the loading zone. The next packet is loaded, the cycle is repeated.
