Description

one

The invention of ognosigs for sawmill production, namely, equipment for the production of sleepers and conversion bars for railways, is intended to rotate the logs on the trolley of a trellis machine.

A device for turning a log is known, which includes a frame, a support, a toothed slide with a flj drive.

Closest to the present invention is a device for turning logs in woodworking machines, including a frame, a rotation mechanism in the form of a reversing shaft mounted on a support with gear segments. And a 2J drive.

Lack of; The known devices consist in insufficiently precise orientation of logs of various lengths, cross section and large runaway, which leads to a decrease in reliability.

The purpose of the invention is to increase the reliability of work.

This is achieved by the fact that the support Bbinoj is not vertical with a vertical hole and is mounted on the frame with the possibility of turning

the company is in the horizontal plane, and the reversing shaft is connected to the drive by means of an intermediate shaft installed in the vertical hole of the support and conical pairs.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, longitudinal section; in fig. 3 is a view A of FIG. one.

A device for turning logs incl. The base 1 with a cylindrical seat, the support 2, the support pin and the neck of which are installed in the thrust bearing 3 fixed in the cylindrical seat of the bed. As a result of this, the support is able to rotate in a horizontal plane. Bearings are mounted on the support, in which a reversing shaft 4 is installed with gear segments 5 fixed on it. Support 2 has a vertical hole in which intermediate shaft 6 is mounted. Intermediate shaft lower bevel gears 7 and 8 are connected to the electric motor 9, and gear pair gearbox 1O and 11 transmits in {) a reversing shaft 4, which, besides rotation in the vertical plane, has the ability, together with the support, to rotate in a horizontal plane relative to the axis of the intermediate shaft. The device is installed between the chains of the transverse conveyor 12. The shpaloreznaya machine carriage 13 is installed on the track and has a stand 14 with a clamp 15 for the log to be processed 16. The device operates as follows. The log enters the transport sprinter 12 into segments 5, the chord of which is located horizontally. The operator from the control panel turns on the electric motor 9. The segment shaft 4 is rotated and the log is fed to the carriage 13 of the hedge saw. In order to securely fix onto the carriage, the log is pressed by the segments to its vertical uprights 14, Brengo segments attached simultaneously to both uprights 14 of the carriage, since the forces applied to the two segments, regardless of the cross-section of the log, become equal as a result of rotation of the reversing shaft 4 together with support 2 in the horizontal plane. The log laid on the carriage is clamped with the help of the clamp 15. Then the operator takes the carriage away from the segments and turns on the feed, while the carriage with the log advances onto the rotating saw. After lane. When the operator saw a reverse cut, reversing the direction of movement of the carriage, returns the cage 13 with the log to the initial position includes a mechanism for lifting the clamp 15 of the log. To rotate the log after the first cut, the operator pushes the carriage with the log onto the segments of the control panel, turns on the electric motor 9. The shaft 4 with the segments 5 is turned. The segments, pressing the log to the carriage legs, are engaged with it, and the log is rotated 9O. The operator then fixes the log pressed to the posts 14 on the carriage 13, and produces the second cut of this log, after which the operation is repeated until the finished product is obtained. The invention includes a device for turning logs in woodworking machines, including a frame, a rotation mechanism in the form of a reversing shaft mounted on a support with toothed segments and a drive, characterized in that, in order to increase reliability of operation, the support is made with a vertical hole and mounted on a frame can be rotated in the horizontal plane, and the reversing shaft is connected to the rim by means of an intermediate shaft installed in the vertical hole of the support, and conical pairs.
