Description

one

The invention relates to the field of machine tools, namely to automatic lines for machining parts in accessories.

A satellite-type automatic line is known from aggregate machines, the working conveyor of which is connected with the satellite-device return conveyor parallel to it by means of transverse chain conveyors equipped with lead plates.

In some cases it is not enough to provide the required program for the production of parts of one automatic line. When using satellite-free automatic lines, an increase in output is achieved by creating two-flow lines in which the loading of the blanks and the issuance of the processed parts from both streams are combined.

For satellite-type automatic lines, parallel installation of workflows is not used because of the need to return the accessory devices to the loading (unloading) position. Therefore, they install several identical c: sets of automatic lines.

However, they occupy a large production area, and the return conveyors of satellite devices are not fully loaded, since the duration of the work cycle of return conveyors is always significantly less than the total time of working cycles of conveyors and limiting machine tools of automatic lines.

The purpose of the invention is to reduce the occupied production area by replacing two automatic lines with one double-flow line.

To do this, in the proposed automatic line, the return conveyor of satellite devices is located between two working conveyors parallel to them, and each of the transverse conveyors is divided into two sections with oppositely directed streams of satellite devices that alternately connect the return conveyor with one of the working conveyors and vice versa, the leads of the cross conveyor moving the devices-satellites from the return conveyor to the working conveyors are set in pairs o in the direction of movement of satellite devices.

FIG. 1 shows the proposed automatic line, general plan view; in fig. 2 is an AA section of FIG. one; in fig. 3-section along BB in FIG. one.

An automatic line consists of two parallel streams of ag3

regatta machines 1 installed according to the technological process and connected with each other and with the loading (unloading) position 2 by two sucker-rod working conveyors 3 and 4, which ensure the movement of the siutnikov devices 5 with the parts to be processed from position to position.

In order to base the working positions of the line, each satellite fixture 6 has base 6 strips, for which it is moved.

Between the working conveyors 3 and 4, parallel to them, a chain conveyor 7 for returning satellite devices 5 to the loading (unloading) position 2, connected to the working conveyors 3 and 4 by chain transverse conveyors, is installed.

One of the transverse conveyors is designed to move the devices of satellites 5 from the working conveyors 3 and 4 to the return conveyor 7 and consists of two sections 8 and 9. On the axles of the driving sprockets 10 of the chains of these sections there are hinged lugs 11 and 12 with counterweights 13, ensuring the stopping of the devices -satellites 5, arriving at the return conveyor 7, in the required position. Screws 14 are used to adjust the stops And and 12.

Another transverse conveyor is designed to move the fixture-satellites 5 from the return conveyor 7 to working conveyors 3 and 4 and consists of sections 15 and 16.

In order to move satellite devices, 5 chain conveyors, part of the chain plates are replaced with lead plates 17, installed with equal clamp. In order to ensure the required travel of satellite devices 5 in sections 15 and 16 of the transverse conveyor, additional plates 18 are installed on the chains of these sections, separated from plates-leads 17 at a distance slightly exceeding the width of satellite satellite 5. Stop at the required The position of the satellite devices 5 coming from the conveyor 7 to return to the sections 15 and 16 of the cross conveyor and from the sections 15 and 16 to the working conveyors 3 and 4 is provided with rigid stops 19 and 20.

Automatic line works as follows.

At the loading (unloading) position 2, the workpiece is installed in the satellite fixture 5, which is then moved by the working conveyor 3 successively through all the working positions of the aggregate machines 1, which are processed.

When the satellite device 5 with the fully machined part has arrived at the last position of the working conveyor 3, and its rods have returned to their original position, section 8 of the transverse conveyor takes effect. Plate leads 17 capture device satellite 5 for the outer surface of the slats 6 and move it

four

on the conveyor 7 return. Moving, the satellite fixture 5 with the strips 6 twice retracts the hinged support 11 and, when it reaches the stop 12, stops and disengages from the driver strips 17 of section 8, after which section 8 stops. The return conveyor 7 is turned on.

The movement of satellite devices 5 on the return conveyor 7 is made

plates installed with a predetermined pitch (not shown in the drawing), similar to the pivot plates 17. At the same time, the abutment of the satellite 5 device 11 stop 11 under the action of the counterweight 13

returns to the starting position.

Each satellite fixture 5 moves to a hard stop 19 and disengages from the carrier straps of the return conveyor 7, which is then disconnected. The section 16 of the transverse conveyor is turned on, and the leash strip 17 captures the satellite attachment 5 on the inside of the front pair of strips 6 and moves it. After disengaging the nlanka-lead 17 with the satellite companion 5, the latter is grasped by the leash strip 18 on the outer side of the rear pair of strips 6 and is extended to the fixed stop 20, after which the leash strip 18 disengages from the satellite attachment 5,

and section 15 of the cross conveyor is turned off. Then the satellite fixture 5 is moved by the shtangovy working conveyor 3 to the loading position 2, and the work cycle of the line section served by the working

conveyor 3 is repeated.

Similarly, the section of the line serviced by the working conveyor 4 is operated. Both sections of the line work alternately, and the satellites 5 are transmitted from the return conveyor 7 to one or the other section of the line, depending on which of the working conveyors 3 or 4 is a free corner position preceding boot

The necessary sequence of operation of all the line mechanisms is provided by a system of interlocks. If necessary, any section of the line can be disconnected, while the second section works as a self-commuting line.
