Для согласования скоростей вращения Приводного барабана 2, транспортера 1 с прижимными дисками 5 и роликомрябухой 4 приводные валы последних имеют жесткую кинематическую связь с валом приводного барабана 2, посредством, например, цепных 11 и зубчатых 12 передач.The device includes a feeding longitudinal belt conveyor 1 with a drive drum 2, placed perpendicular to the longitudinal axis of the multi-feed receiving conveyor 3 and a timber supply mechanism, made in the form of a rowan-tree 4 and drive disks 5 with clamping legs 6. Drive disks 5 are mounted above the drive drum 2 by levers 7 with a spring mechanism 8. The free ends of the levers 7 interact with the stop 9, so that in the initial position, the discs 5 do not touch the conveyor 1. The levers 7 are hinged we are on the axis 10. To coordinate the rotation speeds of the Drive drum 2, the conveyor 1 with the clamping discs 5 and the pulley 4, the drive shafts of the latter have a rigid kinematic connection with the shaft of the drive drum 2, for example, by means of chain 11 and gear 12 gears.

Устройство работает следующим образом.The device operates as follows.

Лесоматериалы различной длины подаются на рольганг, где осуществляется разбег смежных торцов за счет разности скоростей вращения роликов. Затем неорганизованный многорядный поток лесоматериалов поступает на ленточный транспортер 1 и над приводным барабаном 2 прижимается дисками 5 с прижимными лапами 6. При этом количество дисков, воздействующих на сортимент, определяется его диаметром и положением на ленте транспортера. Усилие прижима лесоматериала к приводному барабану 2 и ролику-рябухе 4 позволяет обеспечивать удержание лесо-25Timber materials of various lengths are fed to the roller table, where adjacent ends are run up due to the difference in the rotation speeds of the rollers. Then an unorganized multi-row flow of timber enters the conveyor belt 1 and above the drive drum 2 is pressed by disks 5 with clamping legs 6. The number of disks acting on the assortment is determined by its diameter and position on the conveyor belt. The clamping force of the timber to the drive drum 2 and the roller-rowan 4 allows you to keep the forest-25
