The invention relates to the manufacture of building products, namely, to technological lines for the manufacture of concrete products such as mine shafts.

The purpose of the invention is to increase productivity.

FIG. 1 shows a line, a plan view; in fig. 2 shows section A-A in FIG. 1: in FIG. 3 shows a section BB in FIG. 2

The process line includes stepper conveyor 1, pallets 2 for transporting products, transport carts 3, additional step conveyor 4, molding units 5 and 6, located on both sides of the additional step conveyor, reloading device 7, shifting products on pallets from the step conveyor to transport carts , pushers 8, moving the trolleys to the heat treatment chamber 9 and to the upper rus, reducing agent 10, lift 11, demoulding post 12, pallets clearing post 13, pallets cleaning post 14, pallet lubricants shifting Oddone 15 to products with bogies on demoulding station 12, transfer device 16, forming a package 17, a post 18 forming the package, a roller 19, conveying the package to the bundling machine 20, a roller 21, conveying the package to the warehouse.

The additional stepping conveyor 4 consists of a movable frame 22, a fixed frame 23, hydraulic cylinders of the handle 24, an emphasis 25, a plate 26, spring-loaded stops 27.

Lini works as follows.

The formation of the products is carried out in the molding units 5 and 6. The molded products are pushed onto the pallets 2. With an additional step conveyor 4, the pallet with the products is delivered to the zone of operation of the device 7, which is placed on the transport carriage 3. The upper pallets contact the products with the support racks 28 with the lower through the tabs, which ensures the safety of products and improving their quality in the heat treatment process. The pusher 8 carriage moves to the reducer 10.

With the help of the reducing agent, the trolley is fed into the heat treatment chamber 9, in which the product acquires stripping strength. After the end of the heat treatment, the cart with the lift 11 is removed from the heat treatment chamber and the pusher 8 is delivered to the zone of operation of the device 15, which transports the products with the pallet to the step conveyor 4.

An additional stepping conveyor 4 by moving the movable frame 22 produces separation of the products from the pallet, its cleaning, lubrication and feeding to the forming station,

and also in the working area of the device 7.

The movable frame is driven by the hydraulic cylinders of the handle 24.

The separation of products from the pallet is carried out at the demolition station 12 by the action of the plate 26 on the pallet 2 while simultaneously operating the support 25 on the product. In so doing, the articles are moved to the plate 26, and the pallet passes under the stop 25.

After stopping the movable frame, the device 7 removes the extreme pallet with the products. When the frame 22 moves to its original position, the pallets do not return with it, but are retained by spring-loaded stops 27.

In the initial position of the movable frame 22, the reloading device 16 removes the products from the plate 26 and places them in the bag 17 at the formation post 18. The formed package 17 is fed by a roller conveyor 19 to the dressing machine 20. After the tie, the withdrawal roller conveyor 21, the package is sent to the finished product warehouse.

After that, the cycle repeats.

Claims (1)

Claims of the Invention Technological line for the manufacture of concrete products, containing conveyors located in two rushes parallel to each other, posts of preliminary preparation, molding, placed on the upper rus, on the lower thermal processing, transport carts with means of their movement, pallets, lift-reducers installed at the ends of conveyors, characterized in that, in order to increase productivity, the line is equipped with an additional stepping conveyor with dismantling, cleaning and lubricating pallets, forming and forming packages of finished products and reloading devices installed on it for transferring products with pallets to transport carriages and back and stacking them in bags, post forming - with two molding units located along both side of the additional conveyor. the conveyor is designed as a reciprocating pusher with stops in contact with the pallets. uh and
