supporting roller table 9, two mechanisms for introducing emptying, two mechanisms 11 for the core box, stops 12, metal structures 13 on which all the assemblies and mechanisms for the rod receiving conveyor 14 located outside the closed line contour are mounted.

The core-forming device 1, which is part of the line, consists of a moving inflatable trolley 15, a loading mechanism 16, an inflatable apparatus 17 with a pneumatic cylinder 18.

A cooled roller table 19 passes through the curing oven of rods, above and below which burners 20 are located. Each furnace has eight burners. The mechanism 3 for the pins of the core box and the ejection of the rod comprises a pneumatic cylinder 21 for lifting the crosshead 22 with guides 23 and lugs 24.

The assembly mechanism of the core box and the issuance of the rod consists of a movable carriage 25 on which the lifting cylinder 26 is mounted, lifting the crosshead 27 with guides 28 and grippers 29.

A pneumatic cylinder 30 for driving the piercing plate 31 with pins 32 is located on the cross-beam 27. The pneumatic cylinder 33 for moving the trolley 25 is mounted on the metal structures 34 of the furnace. The design of the grips of the rod holder assembly mechanism and the issuance of the rod ensures that the upper half of the box with the rod is gripped and, being in the lower position, does not prevent the tool from moving at an angle of 90 to the original direction of movement.

Lifting-transmitting devices 5 include two hydraulic tillers 35 for moving the tooling along the working branches, two damping devices 36 for ensuring smoothness when moving and stopping, four splitters 37 allowing the free movement of the equipment in transverse transmission, two mechanisms 38 for lateral transmission providing transmission snap from one branch to another.

The cutter 37 comprises a turntable 39 with a roller 40 and a swinging pneumatic cylinder 41.

The transverse transmission mechanism 38 comprises a lift drive roller conveyor 42 driven by a hydraulic motor 43, a pneumatic head 44 for moving the lower frame 45, horizontal tensioners 46, swing rods 47 and vertical guides 48 The drive roller conveyor has the ability to move in a vertical plane.

There are twelve sets of equipment on the line - twelve satellite-pallets 49 with core boxes 50 mounted on them and push plates 5I.

Lini has twelve working positions, of which: two positions I inflating rods; eight positions II curing rods; two positions of the III connector and the assembly of the suhrsnevy box.

In addition to the working positions, the line has two IV positions for receiving and transmitting tooling and two V positions for issuing rods.

Lini works as follows.

In the initial position on each working branch there are six sets of equipment, of them; one set on position I of inflating rods, four sets on position II of curing the core box, one set on position III of the connector and the assembly of the core box,

The pneumatic cylinder 18 of the clamping device 17 for inflating the rod is in the upper / initial position, the movable inflatable trolley 15 loaded with the mixture is in the upper (initial) position at the inflating position of the rods, the mechanism 3 of the core box connector and ejecting the rod is in the lower (initial) position , the mechanism 4 assembling the core box and issuing the rod is at the connector position and assembling the core box. The lifting drive roller 42 of the transverse gear mechanism 38 is in the lower (initial) position.

The cutters 37 are in the cut-off position. The clamping mechanisms of the core box are in the spin position. At the same time, the mechanisms located at both positions of the inflating rods and at both positions of the connector and the core box assembly begin to work. Their work time is superimposed.

On the position of the inflation of the rods, the pneumatic cylinder 18 of the clamping of the apparatus 17 of the inflatable presses the movable inflatable carriage 15 to the core box 50, centering it.

Mechanisms 10 for introducing emptying agents introduce emptying machines from two opposite sides into the core box, mechanisms 11 for clamping the core box

150 support roller jigs snap to

PG 9. After the tooling is pressed, the core mixture is blown into the crate. inflating rods. After depleting, the emptying devices are removed, the clamping mechanisms I1 release the tooling. The equipment is ready for the subsequent transportation.

At the position of the connector and assembly of the core box, the pneumatic cylinder 21 of the mechanism 3 of the connector of the rod box and the extractor rod raises up

traverse 22, which, with its stops 24 20-roller conveyors 42 in the lower position

The pneumatic cylinder 44 of the transverse gear mechanism 38 moves the lower frame 45 along horizontal guides 46, which, through the swinging rods 47, lifts up the drive roller table 42 along the vertical guides 4 8.

Lifting drive roller conveyor 42,

lifting up, picks up the equipment located on the roller table 6 at the connector position and the core box assembly, and transfers it to another work branch to the acceptance position and

transfer tooling. The lifting drive roller 42. is lowered down to its original position, and the rigging is installed on the receiving roller table 8. After lowering both lift drive roller tables 42 to the lower position

raises up the pusher plate 5 of the core box 50 and, accordingly, the upper half of the core box with the rod.

The yoke 27 of the mechanism for assembling and dispensing the rod by the pneumatic cylinder 26 rises to the upper position, gripping the upper half of the crate with the rod. Then, the yoke 22 of the rod box drawer 3 and ejector mechanism is lowered down to its original position, and the movable carriage 25 is moved to the rod issuing position by means of a pneumatic cylinder.

At the position of issuing the rod, the yoke 27 with the upper half of the box with the rod is lowered down, and when it is raised upward, the pneumatic cylinder 30, lowering the piercing plate 31, pushes the rod from the upper half of the box to the rod receiving conveyor, which removes the rod from the line zone.

The mobile carriage 25 is moved by the pneumatic cylinder 33 to the position of the connector and the core box assembly, the piercing plate 3 is returned by the pneumatic cylinder 26 to its original position, and the crosshead 27 is lowered by the pneumatic cylinder 26, setting the upper half of the box to the lower one. The core box is assembled, the equipment is ready for subsequent transportation.

Upon completion of the mechanisms at the positions of the inflating rods and the positions of the connector and the core box assembly, the mechanisms 38 of the transverse transmission begin operation.
