The proposed line consists of two independent ones, similar to one another, of two branches. Each branch contains a walking conveyor 1, its configuration is made of a base and separately installed fixed bollards 2, an iodine rod 3, made in the form of a welded frame, VIOLO tilter 4, tilt-up tables 5 and multi-position trolleys 6, which may not be made from the tine of the walking conveyor of the drives 7 to the machine 8 for stripping castings. The same carriages are installed at the end of the line and can be moved between the sliding conveyors and the hoppers. Walking conveyors are equipped with chambers 9 to eliminate minor defects in castings. A camera 10 is installed between the branches of the line to correct major defects e with a tilter 11, a crane beam 12, and accumulators 13 and 14.

The multi-position trolley 6 contains a clamping mechanism 15, which consists of a fixed post 16 and a shaft 17 with cams 18 (Fig. 3).

The mechanism 15 is mounted on the shaft 19 of the drive 20 for turning the casting and the drive 21 for moving the carriage. A copier 22 is supported on the fixed rack 16, resting on the cup springs 23 (Fig. 5). A cam 18 provided with a roller 24 and a spring 25 can be pressed by a cam 22. The disc 17 has stops 26 which can press the limit switch 27.

At the ends of the movable rod 3, the supporting platform 28 for the workpiece is mounted with the possibility of vertical movement with rollers 29 mounted on it moving along the copier 30. The supporting platform is equipped with guides 31 mounted on the movable bar 3.

Both branches of the line operate independently but independently of one another. With the help of workshop vehicles, castings are mounted on accumulators 7, the movable rods of which place the casting in the tapered grooves of the disks 17 of the mechanism 15 mounted on a four-position trolley 6. When installing and unloading the casting, the cams 18 are sprung by springs 25, as the rollers 24 are in the depression of the copier . After the casting is installed, the movable shaft of the accumulator 7 returns to its original position, and the carriage 6 is moved by mechanism 21 to the machine 8, where the cleaning of the castings along the contour takes place. At the same time, the casting is rotated 90 ° by the actuator 20, which turns the shaft 19 with the disc 1 / with the cams 18 mounted on it. When rotating, the rollers 24 slide onto the ledge of the copier 22, compress the springs 25 and the cams 18 clamp the casting with 5 cones. To compensate for the allowance on the casting, Belleville springs 23 are installed between the fixed post 16 and the cam 22. The actuator 20 turns off by the stops 26 when they press the limit switch 27.

0 At the end of the casting stripping, the trolley 6 returns to the storage area of the accumulator 7 and the conveyor belt 1. After it stops, the thrust 3 of the conveyor 1 does not move to the trolley 6 with the installed

j on it is putted by casting, while the pad, rolled by rollers 29 along copier 30, rises up and stops under the casting. Then, the movable rod 3 with the supporting platform 28 of the node is removed, the casting is removed, after which the rod 3 is moved to the schag, lowering the supporting platform with the casting onto the base of the conveyor, and then with the subsequent schag - on 2 for further processing. At the end of the walking conveyor, the casting is also placed on the trolley. When moving the rod 3 of the conveyor, the movable rod of the accumulator 7 puts the next casting on the trolley 6.

During the working stroke of the conveyor, the castings move along the working positions.

0 and are rotated with a fork turner, and also lifted and rotated during production operations by elevator tables. 5, located in chambers 9 to eliminate defects in castings, and are processed by operation.

 on cast iron bollards 2.

After processing, the casting with the walking conveyor 1 is placed on the trolley 6, located at the end of the conveyor, which then moves to the accumulators 13 and 14,

where, at the operator’s command, suitable castings are removed by the accumulator m. 14 and sent to undergo the following technological operations, and castings having major defects are removed by the accumulator 13, from where their crane beam 12 is transported to the tilter 11 to eliminate the defects, then the casting after the elimination of the defect sent for re-heat treatment. The line work cycle is continuous.

The proposed line will allow increasing productivity and improving working conditions, reducing the need for lifting equipment for non-unloading operations.
