At present, some types of devices for j.

Protection of the interface on machine tools for processing known from long blanks.

A device for protecting the interface is known

^ one
Ie / machine tool for processing long blanks

The device provides a screen set up on one side of the interface with under the action of Machining long raw parts made of wood represent movable elements. The movable elements are made in the form of rigid metal plates that are hinged in front of the interface are hung in a row sohrag: to limit the movement of the free lower plate ends in the opposite direction to the movement of the Eohteile the device has an immovable stop which is arranged perpendicular to the direction of travel of the raw part. The free lower ends of the

Metal plates give way under the action of the long raw parts to be fed to the interface of the machine tool and, when these raw parts move, interact with their upper and side sections of the outer surfaces. After the raw parts to be processed have passed through the screen, the lower ends of the plate return under the action of gravitational forces to their starting position, which is fixed by the immovable stop _e

A disadvantage of the known facility is its considerable® * Metal expenditure. In addition, the device is laborious and time consuming to manufacture because of the joints and the high demands on the accuracy of the manufacture of the movable elements of the screen - the metal plates.

Another disadvantage of the device is that it

because of the rigidity of the moving elements and lacking Means for covering the clearances does not ensure a reliable hermetic seal of the interface, which Zwlsohen the outer surfaces of the raw parts and the movable elements of the screen - the panels - are formed.

Another disadvantage is that when passing through the Raw parts through the screen, its movable elements, as they are made in the form of rigid metal plates, essential Make noises as their lower ends hit the stop and the side and bottom edges of the panels constantly scrape the outer surface of the raw parts to be machined.

An institution with a similar purpose is also known (e.g. according to the catalog of the company "ARSEHIJE" SPA SIC (Jugoalä-. Vienna), machine tool AS-20 and AS-32, exhibition

"Lesdrevmash", Moscow, September 1979) ι which contains a screen set up on one side of the cut parts of the machine tool with elements that can be moved to the raw parts to be machined.

The moving elements are in the form of sections Executed by round link metal chains, which are in a row at the upper ends in front of the interface of the machine tool are suspended to limit the movement of the free lower chain ends in order to move the parts to be processed Opposite direction unmachined parts, the device has an immovable stop that is perpendicular to the direction of travel Raw parts arranged 1st.

The free lower ends of the chains give way

The direction of travel of the latter decreases and at the same time one part of the chain section is offset to the left, but the other part to the right of the longitudinal axis of the machine tool. After the passage of the blanks duroh the ^above ohirm the lower free chain ends in the return Ausgabst RECOVERY to Ansohlag back under the influence of gravitational forces.

One disadvantage of this known device is its more significant Metal expenditure. In addition, it does not ensure a hermetic seal of the interface of the machine tool because, firstly, the movable elements themselves have openings

<and
Second, when the raw parts go through the durometer, the screen creates clearances between the movable elements and the outer surface of the raw parts.

Another disadvantage is that the screen makes substantial noises from impacts of the coupled chain links against each other, as a result of the during operation of the Machine tool vibrations as well as hitting the lower chain ends against the movable stop.

In addition, the facility is no longer operational bet their erection at the exit of the material on the interface jamming of the free ends of the movable elements between the cut raw parts (boards) possible 1st

The aim of the present innovation is to eliminate the mentioned disadvantages of the above devices for protecting the interface on machine tools for machining of long blanks.

The innovation is the task of the? Developing a Device to protect the interface on machine tools for processing long raw parts made of wood, e.g. from Round wood, which ensures a reliable hermetic sealing of the interface through the development of a new construction of the screen with more rational forms of its movable elements and their new arrangement.

This object is achieved in that in a

Ss 1st) useful if the cross-sectional profile of the

Opening the screen to the cross-section professor of the screen continuous raw part corresponds to.

Such a design of the device enables a complete Hermetic sealing of the interface of the machine tool regardless of the cross-sectional profile of the one to be machined Raw parts

It also creates the possibility of dustiness and

To reduce noise in the machine tool operating area and thereby the working conditions of these machine tools to improve the operating staff.

The essence of the present innovation is that, in contrast to the known devices for the protection of the Interface on machine tools is the hermetic seal the interface by setting up flexible elements of the main screen and attaching to the circumference of the cross-sectional profile of the raw parts to be machined with the possibility of one elastic enclosing the portions of the outer surfaces of the blanks with these elements is solved.

The execution of the facility in the form of in relation

are set up at a certain distance from these in the running direction of a blank 6.

The main screens 2,3 and the additional soles 4,5 and from an elastic fabric such as rubber sheets, and each of them has respective movable flexible members

(1 to 3
7, ö and 9,10 (in Pig.) Are screens with four movable flexible elements shown).

The flexible elements 7,8 and 9-10 of each screen are formed by at least two slots 11 and 12 passing through its central part.

The slots 11,12 and the movable elements 7 «9 and 8,10 of the Naohbarschirme 2,4 and 3,5 are with mutual overlap arranged »

An opening 13 can be made in the center of each screen whose area is less than the smallest cross sonitt area of the raw parts to be machined 6, the transverse

The sectional profile of the opening 13 should correspond to the cross-sectional profile corresponding to the raw parts 6 passing through the screen.

In accordance with the predetermined technology of the Processing of round wood is, for example, the opening 13 in the umbrellas 2 and 4 round and in the umbrellas 3 and 5 on the other hand at right angles. The axis of the openings 13 of the screens 2, 4 and 3 »5 coincides with the longitudinal axis 14 of the machine tool together.

The working life of the establishment is never followed.

When the raw part 6, e.g. a round timber, is fed to the interface 1 of the machine tool, the raw part goes 6 first through the screens 2 and 4 set up at the entrance of the machine tool.

The movable, flexible elements 7 and 9 give way in the feed direction of the blank and enclose under de? Effect of the tension of the screens 2 and 4 firmly the Outer surface of the blank 6 with its working parts 15 *

The between the side parts 16 of the movable flexible Elements 9 of the screen 4 resulting sector rooms are flexible by the surface of the movable Elements 7 of the screen 2 covered.
