Description

than the driveway is parallel to the upper line of the line.

The mold pallet is made in the vnde interconnected modular elements and support bars with grooves installed on the ends of the elements, and the guides are equipped with spring-loaded rollers that enter the grooves of the support bars.

FIG. I and 2 show the conveyor line, general view; in fig. 3 and 4 - sections BB and B-B of FIG. ; in fig. 5 and 6 - connection of modular elements (knot in fig. I and section G-D of fig. 4); FIG. 7 - the node of the mechanism of continuous form feeding (node I in FIG. I).

The line consists of two Rus, the upper Rus 1 and the lower Rus 2. The tiers are equipped with guides 3 for moving the forms 4. On the line there are a lift 5 and a sink 6. On the upper run 1 in front of the lift 5 there is a post 7 retooling, and behind the lift 5 - tilter 8, behind which is mounted a mechanism 9 for the continuous supply of forms of the upper tier. Next, there are molding posts 10 with a paver, vibrating nozzle, finishing devices and. the mechanism of separation forms.

The lower rus 2 is a heat treatment chamber with mechanisms 12 and 13 for pushing and tearing forms.

The retooling station 7 has a tilter 14, an access road 15, a mechanical movement 16 of movement of the molds 16 along the lifting route 15. On the guide lines 3 lines in front of the lift 5, the form pushing mechanism 17 is mounted on the upper tier 1. Lifting nick 5, sandpaper 6, kaitovatel 8 and tilter And have guides similar to the guides of 3 conveyor lines. The guides of the driveway 15 are located in a plane perpendicular to the plane of the guides 3 of the conveyor line.

The pallets of the forms 4 are made of modular elements 18 interconnected with the possibility of vertical displacement relative to each other, for example, with the help of lock washers 19. On the pallets of the forms 4, the landing gear 20 is fastened parallel to the axis of each Modular element 18 bars 21 with grooves 22.

The guides 3 of the conveyor line are made with spring-mounted 23 sliders mounted on them, to which the rollers 24 are attached.

When the molds 4 move in the guides 3, the support bars 21 roll along the rollers 24 and simultaneously press against the guides 3.

The mechanism 9 for the continuous feeding of forms, the mechanisms II and 13 of the separation of the forms are an infinite chain) 25 with hinged attached spring-loaded lugs 26, and the mechanisms of the separation of the forms

each have one stop 26. On the mechanism of continuous feeding of forms, the articulated stops 26 are installed along the entire length of the chain with a distance between them equal to two thicknesses of the transverse sides of the forms and multiple modular E.Pement 18.

The locking washer 19 is a plate with shaped notches 27 for fingers 28 fixed to modular elements 18, and grooves 29 to locks 30 fixed also to modular elements 18.

The special washer 19 is fitted with figured cuts 27 on the fingers 28 of the modular el;

close to each other, and rotated to align the clamps 30 with the grooves 29, while the latch 30 enters the groove 29 with a gap of 2-3 mm.

The work of the conveyor line occurs in the following sequence.

From the fasting station 7, the completed mold 4 is moved by the pushing mechanism 17 (previously, the mechanism 17 is positioned to move the molds from the fasting station, (to fng. {Indicated by a dotted line) along the guide 3 of the upper tier J to its contact with the previous one. The elevator 5 is in the upper position, the tilter 8 is in the horizontal position. One of the articulated stops 27 of the mechanism

0 continuous feeding of forms 9 necessarily captures the end of the just-served form and continuously promotes it together with all the forms of the upper tier 1, which are located close to each other. Moving Forms

will occur at a constant rate, and so. By the way, the forms will be promoted without breaks through all technological posts 10 to the mechanism j 1 of separation of the forms. When the molds are moved in the guides 3, the seated rollers 24 enter into pairs 22 of the support bars 21, thereby pressing them onto the guides 3. At the same time, the modular elements 18 attached to the support bars 21 do not move relative to each other, forming a uniform molding plane of the pallet .

In the area of vibro-compaction between the guides 3 and the support bars 21, shock-absorbing gaskets, such as rubber, are installed.

0 When the molds pass through the zone, vibro-compacting. 31 on the upper shaft 1 vibrates separately each modular element 18. The transmission of vibrations to neighboring modular elements 18 is eliminated due to their visually interconnected connection and by pressing the modular elements to the guides 3 by means of spring-loaded rollers 24 .

The compaction of the concrete mix is carried out due to the combined effect on it.

Claims (2)

about the vibration of the modular element and the vibrating nozzle installed directly above the vibrating section. The mechanism And the separation of forms using a hinge stop 26 captures the last form on the upper tier I, tears it away from the train of forms and feeds to the descender 6. The downer b lowers the form 4 on the lower rus 2 and the pushing mechanism 12 moves it to all the forms of the lower rus 2 on the length supplied by the reducing agent 6 forms. On the lower rusa 2, the concrete mixture undergoes heat treatment. The mechanism of separation by means of a hinge stop 26 tears off the first form 4 of the lower rusa 2 with the finished product from the form train and pushes it to the lift 5, which delivers the form to the upper Russian I. Then the mechanism of pushing and relocates the form to the tilting position after which the product is removed from the mold, and, if necessary, readjustment is transferred to a vertical position until the guiding 3 tilting device 8 is aligned with the rails of the driveway 15. The shape in the vertical position is moved along the rise This way 15 mechanism 16 to the tilter 14, which lowers it to a horizontal position. Then the form is mixed along guides 3 to post 7. Re-arranged, located in front of; 1 lifter 5. At the retooling station, remove the equipment 20; the lock washers 19 and the form pallet are divided into modular elements 18. The modular elements 18 are assembled into a pallet, and their configuration can be any, depending on the size of the molded products, and interconnected with locks, washers 19. Then the ready-made pallet fastens the side equipment 20 and form a new form 4. After that, the finished form is fed into the zone of action of mechanism 9, and the cycle is repeated. The length of the retrofit post is determined by the rhythm of the conveyor line and the number of changeovers. If the mold does not require re-equipment, then after lifting, turning and removing the product, it is shifted to the horizontal position and pushed by the mechanism 17 to the mechanism 9 for continuous feeding and then to the posts 10 of the molding. The proposed construction of the conveyor line, as compared to the existing ones, allows reducing the metal consumption by 15-20% due to almost 1 (using the forms and the process of changeover; reducing the labor costs for changing the forms by 30-40%; Concrete on each modular element.
