line x (all).

A tilter is known that measures the level and direction of movement of the sill plates to the opposite, which contains a multi-light driving roller-gear, built into the drum and having driven gears on both sides, alternately engaging with the drive gear of the roller table. The drum piston is located above the drum and provides its rotation by 180 due to the gear, including the rack and pinion gears 1.

The disadvantages of the known turntable are non-compactness, i.e. large dimensions that exceed the dimensions of the equipment adjacent to the tilter in automatic casting lines, which makes it difficult to maintain and organize, for example, (54)

beer forms and b) bi} sk1; in the areas of AL.P., high dynamic loads, cyclically arising in the gearing of the drive roller table tilter, increased wear of the gears of the drum rotation drive (under strong conditions) and the complexity of manufacturing spare gears of large diameter.

The closest to this technical solution is a tilter for products, mainly of the top plates, containing a base, a drum rotating around a horizontal axis with a multi-roller conveyor embedded inside, having a gear with driven gear, a piston drive of a drum with single-acting cylinders and rods the drive of the roller table with drive gear, mounted on the base -2,

The purpose of the invention is to reduce the size and expand the technological capabilities of the turner. 3 The goal is achieved by the fact that it is equipped with a flexible element, the middle part of which is fixed on the drum, and its ends, passing through the tension pulleys, are attached to each stem of the norshny drive, fixed on the opposite sides of the base, and also equipped with peripheral a series of rollers of the roller table, the working surface of which is displaced relative to the working surface of the central row of rollers in the direction of the axis of rotation of the drum, and the drive of the roller table is fixed on a dead end face of the base and on the axis of rotation), drum, parallel to the direction of movement of articles. FIG. 1 shows a tilter, side view, FIG. 2 - view of the face {deadlock; the side of the turn over with a slit (notch) along the axis of the left cylinder of the piston drive along the collar of the drum; FIG. 3 shows section A-A in FIG. 2, in FIG. 4 - section bb pa fig. 2, in FIG. 5 shows bit bb in FIG. 1. The tilter consists of a base 1 (FIG. 1), a drum 2 with a horizontal axis of rotation 3, inside which a three-row roller conveyor 4 is embedded, a piston drive drum 5 and a roller drive 6. In turn, the piston drive of the drum contains two hydraulic cylinders 7 (Fig. 2) one-sided deist VIY, pneumohydraulic capacitance 8, the calsda of which has a piston rod 9 with a tension pulley 10 fixed on it, sleeve 1 and pneumatic buffer 12. The tilter is equipped with a flexible element 3 (such as day, cable, etc. which is its working body providing Turning the drum onto and which is fixed by its middle part on the crankcase 14, drum 2, and its ends, passing through the tension pulley 10, are fixed on opposite sides of the base 1 using tension screws 15. The drive of the roller table 6 consists of an electric motor 16, mounted on a rotary plate 17, which provides tension on the wedge belt transmission 18, and the worm gear 19 with the pinion gear 20 (Fig. 3), the friction gear 21 and the piston drive 22 for its activation. The friction half coupling 21 is fixed by d with a key 23 (ijuir. 4) on a wap 24, in the long hole of which the floating rod 25 of the reciprocating cylinder 26 of the piston actuator 22 is displaced. The piston 27 of the piston stroke of the 1st piston is fixed on the shaft, on the opposite end of which a piston 28, bearings 29 and 30, and a leading gear gear 20 are installed, playing the role of a friction half coupling. Thus, the piston drive, leading 1 1estelen 20 and the friction half coupling 21 with the shaft 24 is located on the same axis. A collector 31 is located on the same axis for supplying air to the cylinder of the working stroke, semiring 32, bar 33 and worm gear 34. The drum of the tilter consists of a crankcase 14 and a disk 35 (FIG. 3) connected between three canisters 36, 37 and 38. These boxes have a central plane of the plug. They have multi-axle camshafts 39, 40 and 41 with conical cylinders 5 and 42, which transmit rotation, respectively, to three rows of rollers 43, 44 and 45 of the roller table (Fig. 5). The rotation is transmitted from the drive of the roller table through the driven gear 46, shaft 47 and the system of gears located in the crankcase 14 (Fig. 3). The presence of a three-wheel drive roller table in a turn-over device makes it possible to combine the entry time of one product and the output of an already reinterfaced product. To ensure the compactness of the tilting device, the surface of the peripheral () rows of rollers 43 and 45 of the roller table is shifted relative to the working surfaces of the middle row of rollers 44 of the roller table towards the axis of rotation of the drum. In order to restrict the lateral movement and tilting of the products (bed plates) 48, the guide rods 49 are mounted in the tilter, mounted on the middle drum box 37. t The tilter works as follows. In the initial position of the drum 2, when the working surfaces of the rollers 43, 44 and 45 of the roller table are in the horizontal plane and the electric motor 16 is running with the gearbox 19 (FIG. 2), a friction clutch consisting of the pinion gear 20 and the half coupling 21 is engaged.

is produced by a piston drive 22. For this, air (oil is supplied through a manifold 31 into the cavity of the working cylinder 1 and presses on the piston 27 of the piston actuator stroke Lorshen 27 through bearings freely moving along the shaft 24 and half gear 32 transfers force to the pinion gear 20 and bar 33. A smooth coupling of the rotating on the shaft 24 of the half coupling 2 with the pinion gear 20 occurs, which transmits the rotation of the driven gear 46. Next, the rotation is transmitted through the shaft 47 to the gear drive located in the crankcase 14 (FIG. 3). camshafts 39, 40 and 41 and further onto rollers 43, 44 and 45. The rotating middle row of rollers 44 guides the product 48 until it stops against the end of the housing 14. After this, a command is given to turn off the friction clutch and turn the rotator. Compressed air is supplied to air capacity 8

(FIG. 2), presses the oil mirror and forces it through the channels into the hydraulic cylinder 7. There the oil presses the piston 9 and moves it down along with the tensioning pulley 10. The pulley 10 acts on the flexible element 13 fixed on the drum with the middle part , turns it 180 °. The rollers do not rotate during rotation. After rotation, the product 49 from the middle row of rollers 44 (Fig. 5), due to the force of gravity, is shifted (lowered) to the outermost (peripheral) roller row 43 or 45, the latter always rotate in the opposite direction than the roller row 44 and therefore provide the exit of the product from the turner. The time of entry of the next product and the output of the already perekantovannaya combined. Simultaneously with turning the product, the level of its movement changes (after turning by 180), due to the eccentric arrangement of the peripheral rows of poJBiKOB 43 and 45. The tilter can also work to lift the product. To do this, it is necessary to ensure the entry of the product along the extreme row of rollers 43 or 45, and the exit after turning over the middle row of rollers 44. The turn of the tilter in the opposite direction is provided by the second hydraulic cylinder 7 of the piston drive, which also with its 1-pin 9

the tension pulley 10 acts on the second, opposite end of the flexible element 13. The cycle is repeated. The fricking clutch of the roller of the roller table 6 eliminates dynamic impacts in the toothed clutch and ensures that in each cycle the rotation of the roller 43, 44 and 45 of the roller table is turned off during rotation of the cable. DTILM also reduces gear wear, i.e. increased reliability. Using more flexible element 13 and the displacement of the working surfaces of the periphery rollers (5 rows of rollers in the direction of the axis of rotation, in combination with the BbmjeoHHca arrangement of the piston drive of the drum and the drive of the roller table, ensure the positioner is compact.

u All of this was confirmed when tested under production conditions on an ALL,

The expected economic effect, which is assumed nojiiT-n-iTb from 25 implemented and invented, will be more than 200 thousand rubles.
