SU380572A1 - DEVICE FOR UNPACKING PUTS OF logs - Google Patents

Description

one

The invention is intended for rolling packs of logs and can be used at timber transshipment bases, exchanges of raw materials for pulp and paper mills and other enterprises where wood is unloaded from wagons, ships, rafts, etc.

A device for rolling packs of logs is known, which includes a frame, a screw roller table, a cross conveyor for removing bark, a machine for uncoupling, a raskatochny platform and a bender.

The known structure of the unwinding device does not provide a clear single-piece feed, it allows the logs to skew. Hitting waste on the teeth of the leading sprockets of the cross conveyor causes a break of the chain. In addition, they are metal-intensive, energy-intensive and expensive to manufacture.

The purpose of the invention is to provide a single log feed.

The goal is achieved by the fact that the device is equipped with hydraulic tillers with reciprocating fists and a segment shut-off device with a switch sensor installed on the conveyor belt.

FIG. 1 image of the proposed device, the cross section; in fig. 2 - unrolling device, plan view; in fig. 3 - fist with hydraulic cylinder.

The device for rolling packs of logs includes a welded frame /, hydraulic cylinders 2, on the rods of which cams 3 are fixed, screw conveyor 4, end shield 5, cutter 6 with hydraulic cylinder 7, drive of roller table 8, hydraulic drive 9, control console 10, cutter switch 11, machine 12 for uncoupling, conveyor 13 for bark harvesting, unrolling of the block 14.

The device works as follows.

A bundle of logs is delivered by a crane to the unrolling platform 14, and the machine 12 is detached from the bundle. Next, the hydraulic drive and the screw conveyor 4 are turned on.

The logs from the riveting area 14 are driven by the cams of 3 hydraulic cylinders 2 of the first row from the roller table, several shafts are fed to the screw roller table, where they are rolled into a single shaft. When they return, the fists are sunk in their guides, and during the working stroke they rise, which ensures the capture of logs. If the logs are skewed, the operator aligns them by individually turning on the desired cylinder.

After selecting a log from the bundle with cams of the first row, cams of the second row are turned on, etc. The rotating rollers of the worm roller table

4, the helix moves the logs along the rollers for the segment cut-offs 6. The latter, at the command of the sensor II, turn the hydraulic cylinders 7 down; the log lying on the end of the rollers is fed to the longitudinal sorting conveyor by the next log. When the log is acting on the sensor flag, the cut-offs with the hydraulic cylinders turn, lift up, and prevent the next log from rolling on the sorting conveyor. After the conveyor is cleared from the log, the cut-off devices turn, feeding the next log, etc.

Subject invention

A device for rolling packs of logs, including a frame, a screw roller table, a facing shield, a conveyor for removing bark, a machine for uncoupling and a roll out area, characterized in that, in order to ensure the feed of logs by piece, the device is equipped with hydraulic rollers

reciprocating fists and a segment cutter with a shift sensor mounted on the conveyor.
