The purpose of the invention is to increase productivity.

FIG. 1 shows the proposed line, plan; in fig. 2 shows section A-A in FIG. 1 (auto operator at the time of passage under the welding post); in Fig. - 3 - section. BB in FIG. 1 (trans-manipulator, loading and unloading posts and picking tables); figure 4 is a view In figure 2 (auto-VIEW front); in fig. 5 is a section of YYD in FIG. 4 (copying roller of an auto operator and the safety of one of the posts); in fig. 6 is a view of D in FIG. 5 (interaction of the copy roller and the catcher) in FIG. 7 - node I in FIG ,, 4 (the connection of the lifting mechanism with the gripper conductors).

The transgurt-technological line contains transport route 1, welding stations 2, auto-operator 3 and trans-manipulator 4, post 5 downloads and post 6 unloading. Transport route 1 passes through all equipment lines.

At the beginning of the journey, 1 side by side with the loading post 5, the picking tables 7 are installed with accumulators 8 of conductors placed inside them 9. Tables 7 have stops 10 for conductors 9.

In the case of a stop at each post 2.5 or 6, the gripper interacts with catchers with a picker roller, which, displacing the gripper in the horizontal plane, centers it relative to the post. When the conductor is unloaded, the metal structure is added to the accumulator 25. After the conductor is filled, the accumulator is moved to the post 5. 1 3.p. f-ly, 7 ill.

The picking tables 7, the loading post 5 and the unloading post 6 are interconnected by a trans-manipulator 4 mounted for movement on the portal 11. The auto-operator 3 is made in the form of two traveling carts 12 and a supporting frame 13 connected to the carts 12 with vertical hinge supports 14 The auto operator 3 has a lifting mechanism 15, made in the form of a scissor-type stabilization mechanism and a 1 & drive, for example, in the form of a screw-nut transmission;

On the lifting mechanism 15 by means of pins 17 mounted. Gripper 18 conductors 9, and the gripper 18 is spring-loaded relative to the mechanism 15. movable in a plane parallel to the plane of movement of the auto operator.

On the tong 18, the rods 19 are installed with copying rollers 20 la end, on each post 2 there are rotary locks 21 and catchers 22. On the tong 18 there are pins 23, and on the conductors 9 there are counter slots 24. Between post 5 and post 6 with the possibility movement in the direction of movement of the trans-manipulator 4 is installed drive 25.

The transport and processing line is equipped with a control system, the elements of which are not shown in the drawings.

The transport and processing line can be operated in a variety of ways, depending on the number of car carriers and transmanipulators.

With a minimum number of them (one by one), the line is operated in the following order.

In the initial position (for example, at the beginning of the work shift) at each station 2 there is a jig 9 and the products are welded. In this case, the jig 9 lies on the latches 21. The auto operator 3 is at the post 5 loading, and on the tables 7 there is a set of conductors 9. At the end of the welding work at one of the working positions the auto operator 3 with the lowered tong 18 pulls up on the path 1 and stops at the post 2 After this, the actuator 16 is turned on, which causes the mechanism 15 to lift the girth 18. At the same time, the rods 19 are engaged with the catchers 22 through the rollers 20, and if the axes of the catcher 22 and the roller 20 do not coincide, a force arises that forces the gripper 18 move due to displacement It is positioned on the pins 17. As a result, the exact positioning of the conductor 9 relative to the clamps 21 occurs. The gripper 18 raises the jig 9 above the level of the clamps 21, after which they are removed, and the gripper 18 returns to its original position on the support frame 13. The trolley 12 turns on and auto operator 3 is fed to post 6 unloading. There, with the aid of the transmanipulator 4, the auto-operator 3 is unloaded and the conductors 9 are fed to the movable drive 25. After that, the auto-operator 3 is fed to the post 5 of the load, and the jig 9 is laid on it, which is fed to the vacated work post. The conductor 9 is mounted in the reverse order of its removal.

When the auto operator 3 moves on curved sections of the track 1, the frame 13 rotates relative to the carriages 12 on the hinge bearings 14. During the transport operations by the auto operator 3, the collectors 4 remove the jig 9 from the accumulator 8 by means of the manipulator 4, then install it on the stops 10. Next repeats.

As the conductors 9 out of the accumulators 8 are consumed, they fill in a 55418

25. The overload of the conductors 9 by the transmanipulator 4 of the accumulator 25 is carried out at the post 5 after it is supplied from the post 6 of the transport route 1, while the loss of time for performing transport-overload operations is minimal. When performing loading and unloading and transport operations, transmanipulator 4 moves along portal 11.

The proposed line allows to increase the productivity by reducing the time for fixing conductors 1g and using accumulation-ere- installed - .HOFO with the possibility of moving from the loading point to the place of discharge of the conductors.
