Description

Known planers for machining the cut-off sleepers of the sleeper have the disadvantage that they can process the sleeper from the sides on one specific profile, taking into account only the width of the sleepers. In the case, if the sides of the rollers are different in the sleepers, which is often found in practice, and sometimes in the sleepers and voobsh. On the one hand, there is no glare, in such cases the mentioned machines uselessly remove significant layers of wood, which leads to irrational use wood in general, excessive energy consumption for mechanical processing and, as a result, to obtain low-grade wood from high-grade sleepers.

The invention relates to a device for the installation of the same purpose with the use of guides on it, which are adjustable along the width of the scale; In the proposed machine, in order to handle the blisters of various types of sleepers, the directions for the sleepers are made in the form of boxes provided with openings for pull-out knife.

In FIG. 1 is a top view of the machine; FIG. 2 - perspective view of the machine.

Side guides 1 VI 2 are applied on the frame of the machine on which two pairs of rows 3 (Fig. 1) are installed for pulling between the rolls of the processed sleepers. bearing knives 6 (Fig. 2). Rollers 7 are installed on the inner vertical shelves of the guide boxes to reduce the resistance of the processed sleepers. Guide box 1 Depending on the width of the sleepers, the cross ties can be rearranged in the transverse direction, which is achieved by using the gears S, rolled along the gear racks 9, connected with the guide, box and sitting on the same common axis 16 /, 10, controlled by the pedal. The guide box /, in addition, is connected with the common bed of the machine by means of spring-loaded stops 17.

The knife heads 5, placed in the hollow of the guide boxes I, 2, are mounted on a common drive shaft 18 and through the side windows in the boxes can be moved along the shaft by means of leads 14 connected with the layouts 12,13 and controlled by levers 15,

When processing sleeper sleepers, each of the knife heads extends to the processed tie by an amount corresponding to the value of the blind, and if there is no wane at any side, then the cutter head does not advance from this side, and the processing of the sleepers is performed in that case one side.

For the purpose of uniform cutting off the surface of the chip sleepers, knives 6 were used as cutters (Fig. 2), the blades of which have the shape of the sleepers of the sleepers, and the middle part of the knife plane is concave.

The subject matter of the invention.

A planing machine for machining the cut-off sleepers with the use of sleeper guides, which are adjustable in width, characterized in that the sleeper guides are made in the form of boxes with openings for retractable knife heads for the processing of cleavages of various types of sleepers.
