the lateral guides 11 of the conveyor 1, and the forks 10 of the chains of the conveyor 1 cover the front axes of each cradle in the direction of travel. On the vertical conveyor, 2 cradles 5 are suspended by their grippers 30 on the fingers 16 of the conveyor 2 with cradles pitch, while the vertical rows of the cradles rest with their rollers on the vertical movable strips 17. The slip from the dispenser 7 is poured into molds 6 installed in the cradles 5, then horizontal conveyor 1 moves the cradles placed on it one step. With further movement of the conveyor 1 from the dispenser 7 to the end of the trans1

The invention relates to the production of ceramic products, such as household porcelain, by the method of casting and can be used in the manufacture of stroyfarfora.

The aim of the invention is to increase the reliability of the installation.

Figure 1 shows the installation, General view; Fig. 2 shows a clutch assembly of a cradle with a horizontal conveyor; fig.Z - the same, with a vertical conveyor; on fig.ch diagram of the drive rotary nozzles; Fig. 3 shows the means | D of adjusting the inclination of the cradles when the slinker is drained from the forms.

The installation contains a vertically closed transporting body consisting of a horizontal chain conveyor 1 and a vertical chain conveyor 2 with drives 3 and 4, respectively. On the conveyor chains and 2, there are cradles 5 with casting molds 6. In the installation there are also a dispenser 7, a dryer 8, located inside the vertical conveyor 2, and a post 9 sampling of molded products from the molds.

The FORCH1 10 is rigidly fixed to the chain of the horizontal conveyor 1 (Figures 2 and 3), and the conveyor itself is provided with side guides 11 fixed to the base and having a channel profile and sprockets 12.

porter in forms 6 a shard of products is formed. At the end of the conveyor 1, the cradle overturns, freeing the molds from excess slurry, is kept for some time in an inclined position, then moves along the lower branch of the chain, where the molded products are drawn, and finished products are removed from the mold post 9. The wetted molds will return to position 33, common to both conveyors, from where they will go to the vertical conveyor 2, picked up by his fingers 16, to the grips of 30 cradles, where the drying of the molds takes place. 3 3.p. f-ly, 5 ill.

On the guides 11, a device is installed to remove the excess of the slip from the molds, consisting of two spherical 11 sectors 13 with slits 14 and a common clip 15 attached to the side guides 11, to enable the sectors to move relative to each other.

The fingers 16 are mounted on the chain of the vertical conveyor 2, and the conveyor itself is provided with means for tilting the cradles, which are vertical movable strips 17 attached to the frame 18 with the possibility of changing the distance between them and the chains of the conveyor 2 by means of screw pairs.

Inside the vertical conveyor 2 there is a dryer 8 with a ventilation duct 19, equipped with rotating nozzles 20, rigidly fixed on axis 21 with a driving lever 22 for simultaneous rotation by means of an actuator consisting of a flexible link 23, rod 24, a hook 25 hinged to the rod 24, a disk 26 with fingers 27, sitting on the drive shaft of a horizontal conveyor 1, disengaging the lever 28 and the spring 29 of the reverse stroke.

Lolki 5 syabzheny side grippers 30 and rollers 3, sit on ax x 32.

Assembled installation is as follows. The horizontal conveyor 1 is filled with cradles 5, except for one position 33, from which the cradles are transmitted to the vertical conveyor 2. The cradles with their rollers 31 stand in the side rails 11, and the forks 10 of the chains of the conveyor 1 cover the front axles 32 of each cradle along the way.

The vertical conveyor 2 is completely filled with cradles, which are suspended by their grippers 30 on the fingers 16 with pitch of the cradles, while the vertical rows of the cradles are supported by their rollers 31 on the vertical movable strips 17 of the means for tilting the cradles.

In the drier 8, the nozzles 20 of the ventilation duct 19 are directed to the mouths of the casting molds.

The second common position for the two conveyors is the position 34 where the cradle is transferred from the vertical to the horizontal conveyor.

The installation works as follows.

The slip from the metering device 7 is poured into the casting molds 6 fixed on the plate 5 installed at the metering position of the horizontal conveyor 1. After filling the slip into the molds, the horizontal conveyor 1 moves the cradles placed on it one step. Through the forks 10, which are linked to the front axles of the 32 cradles, the latter are moved one position, while the empty position 33 is occupied by the next cradle. and position 34 is released.

A cradle with molds filled with a slip moves from the dispenser 7 to the end of the conveyor 1, and a shard of products is formed in the forms. At the end of the conveyor, 1 cradle tilts

c, freeing the molds from excess slip, while preventing the occurrence of a drop in the center of the bottom of the product, it lasts for some time in an inclined position, the angle of which is set by means for adjusting the cradle inclination by mutual movement of the sectors 13 due to iprorez 14 and clamp 15.

The angle of inclination of the forms is determined specifically for each type of product, depending on their configuration.

After draining the slurry, the lups with molded products are moved along the lower branch of the chains, where the molded products are fed up, and the cradles are re-rotated by the chains and transferred to their upper branch and removed to the post 9, samples of the products, where the subsurface products are removed from the molds.

The wetted molds, after fasting 9, the product selection is moved to pos. 33, common for both conveyors, from where the cradle with the molds is fed to the vertical conveyor 2

for Qy, moistened forms in the dryer 8 by picking up 16 chains of the vertical conveyor 2 with the side grips 30 of the cradle, and the axles 32 of the cradle disengaging from the forks 10 of the conveyor chains, 1.

In the dryer L, the humidified forms are dried by directional air flows. The nozzles are freely seated on the duct nozzles 19 and rigidly fixed on a common axis 21, which through the drive lever 22, the flexible coupling 23, the stem 24 and the hook 25 receive rotation from the two-finger drive 26 26, which sits on the drive shaft of the horizontal conveyor 1, and rotates the nozzles 20 before the movement of the vertical conveyor 2, giving passage to the molds.

The nozzles are retracted when the horizontal conveyor 1 moves by engaging the finger 27 of the disk 26 with the hook 25 of the rod 24, which through a flexible link 23 with a driving lever 22 rigidly fixed on the axis 21 turns the axis to the required angle.

The nozzles are returned to the initial position while the vertical conveyor 2 is moving, when the cradle presses the disconnecting lever 28,

which lifts the hook 25 and looses it to engage with the pin 27 of the disk 26, while using the spring 29 acting on the drive lever 22, the nozzles 20 are returned to

working position.

The cradle with dried molds again returns to conveyor 1 at position 24, with the rollers 31 that are forward in the direction of movement of the axis 32.

the cradles, moving from top to bottom, enter the sheds of 10 chains of the conveyor 1, and the fingers 16 of the chains of the conveyor 2 come out of engagement with the side grippers 30 of the cradles 5.

From position 34, cradles with molds again come under dispenser 7 for re-filling the slip into the molds.

The invention provides an increase in the reliability of operation of the installation by separating the conveyor, allows to mechanize the foundry production of large-sized shaped ceramic products.
