SU76746A1 - Gravity Log Roll - Google Patents

Description

The invention relates to devices made in the form of parallel, obliquely positioned plank beds, along which logs are rolled under the action of their own weight. During the descent of cone-shaped logs, their butt end will be ahead of the movement of the thin end and at the same time go down to the end towards this end and break the descent.

To eliminate this drawback, in the device according to the invention, rails are used, located between the main benchways parallel to m and provided with stops, thanks to which the braking of the log that came down from the bench and automatically rolling it back onto the floor is applied.

The main rolling structures (in three projections) are shown in FIG. 1-3; in fig. 4 and 5 - two options for sections of the Main Leg; in fig. b - option of stops made of crutches; and FIG. 7 and 8 are two projections and versions of the stops using rollers.

The slope consists of ne located obliquely parallel lying legs interconnected by means of transverse lines 3. Between the lower levels, pa4G

parallel to them, are slats 2, reinforced on the same crossbars and provided with stops 4, the upper faces of which are placed slightly below the working surface of the legs.

When rolling logs that have a taper, their butt end will be ahead in movement of the thin end and roll down from the deck onto the adjacent rail, the stops of which will slow down the butt and slow it down. Then the thin end of the log will start moving faster than the butt and will ensure that the butt end will automatically roll onto the plank.

For more reliable rolling of the butt ends onto the hollow, the latter should have a circular cross-section (Fig. 4) —or their working surface should be flat and inclined towards the rail (Fig. 5). The stops on the rails can also be made of crutches (Fig. 6) or in the form of rollers (Fig. 7 and 8).

The subject of the invention is I. A roll for gravitational descent of logs, made in the form of two parallel beds, characterized in that, in order to keep logs having a tapered shape on it, between the beds

reinforced rails with stops located below the working surface of the legs and designed to brake the forward running and crawling from the dead end of the log.

2. The form of rolling performance according to claim 1. characterized in that

the rail is provided with sawtooth teeth that play the role of stops.

3. The form of rolling performance according to claim 1, characterized in that the rail is provided with rollers mounted in the rolling plane at an angle to its longitudinal axis.
