Abstract

The invention relates to mechanical engineering and can be used to create automatic lines. The aim of the invention is to increase the reliability of the automatic line. The workpiece 12 on the table-satellite 10 is fed through the conveyor 9 to the cutter 11 of the first machine, then View A, the first gripping hand 6 removes 1 piece 13 from the machine, and the second hand sets a new workpiece. The carriage 5 moves until the sensor 7 is triggered. After the carriage 5 stops, the second gripping hand 6 takes the carving 12 from the satellite table 10, then the carriage moves until the unloading sensor 8 triggers and the first gripper hand 6 places the part 13 on the satellite table 10. In As a result of the displacement of the carriage 5, the machined part 13 receives an axial displacement relative to the drive conveyor 9 p compared with the position of the workpiece 12 on the conveyor. Sensor 14 is set in a CMM manner that reacts to the displacement of the part 13 and registers only the machined parts. 2 Il. (L is rotated WITH Nt; 00 oo Fig. 2

Description

one

The invention relates to mechanical engineering and can be used to create automatic lines.

The purpose of the invention is to increase productivity.

FIG. 1 shows an automatic line, a plan view; in fig. 2 is a view A of FIG. one .

The automatic shaft processing line contains parallel-working machine tools 1, portals 2, transport system 3 and line control system 4. The portals 2 have a movable carriage 5 of an auto-operator equipped with a two-handed gripper 6 and sensors 7 and 8, respectively, of the loading and unloading positions of the carriage 5 located above the driving conveyor 9, with the unloading position sensor 8 being set offset from the loading position sensor 7. The transport system of the line includes a drive conveyor 9, tables-satellites 10 and shut-off devices 11. Cut-off devices 11 are installed on the conveyor 9 in the areas of activity of the grippers of 6 gantry operators. Tables-satellites 10 moving along the conveyor 9 contain two prisms on which either the workpiece 12 or the workpiece 13 is installed. In addition, contactless sensors 14 for the presence of workpieces and sensors 15 are installed on the conveyor belt at the loading position of the machine.

Automatic line works as follows.

The workpiece 12 on the table-satellite 10 is fed through the conveyor 9 to the compartment 11 of the first machine, at which time another workpiece is being processed. After finishing the processing, the first arm of the grip 6 of the gantry auto-operator from the machine 1 processed the part 13, and the second hand establishes a new workpiece.

The carriage 5 moves until the sensor 7 is activated. After the carriage 5 stops, the second gripping hand 6 picks up the workpiece 12 from the satellite table 10, then the carriage 5 moves to the right until the sensor 8 triggers and the first gripper hand 6 places the machined part 13 on the satellite table 10.

As a result of the last movement of the carriage 5, the machined part 13 receives an axial displacement relative to the drive conveyor 9 in comparison with the position of the workpiece 12 on the drive roller table 9. The non-contact sensor 14 is set on the roller table so that it reacts to the offset obtained by the processed part 13 and, accordingly, registers only processed parts.

According to the command received from sensor 14, the cutter 11 passes the table satellite 10 with the processed part 13 further along the conveyor 9. When passing the table satellite, the loading positions of subsequent machines at each position are triggered by the sensor 14 and the cutters 11 freely pass the table satellite 10 with the machined part 13 to the end of the roller table, where the finished part is removed from the satellite table 10 and placed in the container. When a ground is formed from the blanks 12 on the first machine's shut-off device 11, the uniform loading of all parallel working machines is carried out by the line control system 4. Having received the sensor signal 15 about the absence of the table-satellite 10 at the loading position of one of the machines, the line control system 4 issues a command to the cutter 11 of the first machine. At this command, the cutter 11 passes one table-satellite 10 with the workpiece 12 to the cutter of an unloaded machine. In case two machines are not loaded, the machine is loaded first, standing the last in the course of movement of the satellite tables. In this way, backlogs of the workpieces are formed on each of the parallel working machines.
