Description

The invention relates to the production of building materials, namely the production of lightweight cellular concrete products.

Known conveyor line for the manufacture of cellular concrete products by auth. USSR N 1708626 (publ. 30.01.92), containing a transport route for moving pallets having guiding supports, removable board equipment located in the technological sequence of pouring, molding of aerated concrete mass, holding, stripping, mass cutting and autoclaving.

A known method for the manufacture of cellular concrete products described in the description to ed. USSR N 1708626 (publ. 30.01.92), on which the cellular-concrete raw mix is poured into a mold, molded and kept in an array until it reaches raw strength, disassembled, the raw mass is transported on a pallet along a conveyor line, cut into an article and subjected to mass their autoclaving.

The disadvantage of this line and method is that it is difficult to obtain high quality products on this conveyor line, because with a large length of the product, it is impossible to ensure the accuracy of cutting the product.

Closest to the proposed and free from its shortcomings is the conveyor method and line described in the patent of Germany N 1584845 (publ. 16.03.64). According to this method, the raw mass after maturation is turned over to a longitudinal face, which makes it possible to obtain products with the necessary cutting accuracy, which can be obtained with a cutting length of not more than 1 meter. For this, the mold is made with a removable side board. After turning the mold over to this board, the mold is taken apart, the rest of the mold is removed and the array is then moved between technological operations on this board, used as a pallet.

The disadvantage of this method is that during barothermal processing, the cut products stick together horizontally under their own weight, which requires the use of explosive equipment, which occupies a significant area, increases the metal consumption of the equipment.

The present invention solves the problem of obtaining high-quality products with the necessary cutting accuracy, reducing metal consumption and increasing productivity of equipment, as well as achieving complete automation of production.

To achieve the technical result, a conveyor line for the manufacture of cellular concrete products containing molds, trolleys, transport paths for moving molds located in the technological sequence, posts for filling and forming the cellular concrete mass, holding, stripping, massif cutting, autoclaving and mold assembly on the transport path of the return of pallets, equipped with a device for the reverse canting of the array, including a frame that has the ability to horizontally and vertically moved I, and two cheeks mounted on it coaxially and articulated, consisting of two kinetically connected parts, on these parts of the cheeks there are shelves for holding the autoclave tray and removable side, mounted at an angle of 90 ° to each other, and freely rotating clamps, and the device for the canting of the array is placed after the post cutting the array.

Distinctive features of the proposed conveyor line for the manufacture of cellular concrete products from the previously known is that it is equipped with a device for reverse tilting of the array, including a frame that has horizontal and vertical movement, and two cheeks mounted on it coaxially and articulated, consisting of two kinetically connected parts, on these parts of the cheeks there are shelves for holding the autoclave tray and removable side, installed at an angle of 90 ° to each other, and freely rotating ora, and the device for canting the array is placed after the post cutting the array.

To achieve the specified technical result in the conveyor method for manufacturing cellular concrete products, including the preparation of the raw mix, pouring it into the mold, molding, curing the array, tilting and disassembling the mold, cutting the array into products, autoclaving the products, assembling the mold on the mold return transport path , after the operation of cutting the array, the array is tilted back to the horizontal position by means of the array canting device, which is brought under the autoclave pallet, raises it px, turns 90 ° with the face of the autoclave pallet in the direction of the vertically standing array, leads to the array, going as a part of the cheeks under the removable board on which the array is located, then the array is lifted and rotated in the direction of the autoclave pallet, after which they are in a horizontal position an autoclave pallet with an array is mounted on a trolley, and the device is pulled out from under the autoclave pallet, rotates 90 ° and transfers the removable board to the return path.

Distinctive features of the proposed conveyor method for manufacturing cellular concrete products from previously known is that after the operation of cutting the array, the array is tilted back to a horizontal position, by means of a device for tilting the array, which is brought under the autoclave pallet, raises it up, turns it 90 ° the front surface of the autoclave pan in the direction of the vertically standing array, leads to the array, going as part of the cheeks under the removable board, which is placed Then the array is lifted, then the array is lifted and rotated in the direction of the autoclave pallet, after which the autoclave pallet with the array in a horizontal position is mounted on the trolley, and the device is pulled out from under the autoclave pallet, rotated 90 ° and transfers the removable board to the return path .

Due to the presence of these features, the proposed conveyor line and the conveyor method for manufacturing cellular concrete products increase the productivity of equipment, automate production, and obtain high-quality products.

The proposed design is illustrated by the drawings shown in figures 1-6.

Figure 1 shows the conveyor line for the manufacture of cellular concrete products

Figure 2 shows the reverse tilter.

Figure 3-6 schematically shows the principle of reverse canting,

 where in Fig.3 shows the first part in which the autoclave tray is taken from the roller table and brought to the array,

figure 4 shows the second part in which the array with two pallets (autoclave and removable) is transferred to the autoclave trolley,

figure 5 shows the third part in which the tilter transfers the removable pallet to the roller conveyor return,

figure 6 shows the fourth final part, in which the tilter returns to its original position.

The problem is solved as follows.

The conveyor line for the manufacture of cellular concrete products (figure 1) contains a molding post 1 and maturation posts 2, along which the movement of forms 3 is carried out by an electric transmission bridge 4. Matured arrays move along the tracks under the first tilter 5 (direct canting).

The first tilter 5 takes the mold with an array, transfers it to the cutting line 6, rotates 90 ° (turns over the longitudinal edge) and sets the removable side on the cutting carriage 7 of the cutting line. After opening the locks and lifting the form, the removable board with a vertically standing array remain on the cutting trolley 7.

The cutting trolley 7 with the array starts moving along the cutting line 6 and alternately passes the calibration and horizontal slitting 8 and the vertical cross cutting machine 9. After the end of the cutting, the trolley with the array moves to the end of the cutting line and stops at the pick-up point. At this post, the array is tilted back to a horizontal position with simultaneous stacking on an autoclave pallet using a reverse canting device 10.

The device for the reverse tilting of the array 10 (figure 2) consists of a frame 11, which has the ability to horizontal and vertical movement. Two cheeks are coaxially and articulated on the frame, and the cheeks consist of two kinetically connected parts 12, 13. On the parts of the cheeks there are shelves 14 and 15, the one on part 12 is designed to hold the autoclave tray, and the one on part 13 is to hold the removable side. The shelves are installed at an angle of 90 ° to each other. On the component of the cheeks 12, latches 16 are installed. The cheeks can rotate 90 °, providing a horizontal or vertical position of the autoclave tray 17 and the removable side 18. The latches 16 are stops that rotate freely on the axes, which hold the autoclave pallet 17 in a vertical position when turning the cheeks 90 °, because the latch 16 seek to maintain its original position and at some point rests on the autoclave pan, preventing it from tipping over. Upon reverse rotation of the cheek, the latch moves away from the autoclave pan and does not prevent its removal from the cheek.

An autoclave pallet 17 (Fig. 1) with an array 19 lying horizontally on it is mounted on an autoclave trolley 20. The freed removable board 18 is installed on the roller conveyor 21 of the return of the removable sides 18 and is moved to the area of operation of the first tilter 5.

Form 3 (without a removable side), vertically hanging on the tilter 5, is moved by the tilter to the roller table 21 for returning the removable sides, lowered onto the cleaned removable side 18, fixes it to the form with locks, raises, rotates 90 ° to the horizontal position and transfers it for lubrication and refill.

Trolleys 20 loaded with autoclave pallets with arrays (up to 3 pieces) are moved along the equipment path 22 towards the autoclave compartment and are installed in autoclaves 24 using the power transmission bridge 23.

At the end of the barothermal treatment, the trolleys with steamed arrays are transferred to the unloading path 25 by the transfer bridge and through it under the transferring device 26. The transferor removes the autoclave arrays from the trolley and transfers them to the conveyor 27. Empty autoclave pallets 17 are installed on the rolling table 28 and fed into the coverage area reverse tilter 10. The freed trolleys 20 are moved along the discharge path 25 and, with the help of the transfer trolley 29, are fed to the picking path 22 into the operating range of the reverse tilter 10.

The operation of the reverse tilter is shown in FIGS. 3-6.

Figure 3. The reverse tilter 10 drives by the shelves of the cheeks 14 under the horizontally lying on the rolling table 28 cleaned autoclave tray 17, raises it up and rotates 90 °. In this case, the pallet is fixed from overturning by the latch 16. The tilter 10 with the autoclave pallet 17 is fed to the array 19 (a vertically standing removable side 18 on the cutting trolley 7), while another pair of shelves 15 on the cheeks comes under the removable side 18.

Figure 4. Upon reaching the contact of the autoclave pallet with the array, the tilter 10 begins to lift the array 19 with the detachable side 18 and the pressed autoclave pallet 17. In the upper position, the tilter turns the cheeks 90 ° in the opposite direction so that now the autoclave pallet 17 assumes the initial horizontal position, the array 19 lies on the autoclave pallet 17, and the removable board 18 in a vertical position is pressed against the array 19. Parts of the cheeks 13, on which the shelves 15 of the removable board holders are located, are moved away and the removable board 18 is removed from the array 19. When The undercut layer falls into the cutting waste collection channel and is used to prepare the secondary sludge. The tilter moves the autoclave tray with the array and installs on the trolley 20.

Figure 5. Cheeks 12, 13 of the tilter with a removable side 18 are removed from under the autoclave tray 17 mounted on the trolley and rise. The cheeks are rotated 90 ° so that the removable side 18 is in a horizontal position, carry and set it on the roller conveyor return removable sides 21.

6. The cheeks of the tilter 12, 13 are brought out from under the removable side 18, raised, rotated 90 °, moved to the starting position, lower and extended the extended parts of the cheeks 13.

The proposed invention allows the manufacture of cellular concrete products with higher productivity, less metal equipment and smaller production areas (there is no need for explosive equipment). Tilters allow for direct and reverse tilting of the array without damage. All operations are carried out in a conveyor way without involving additional crane equipment and allow a high degree of automation.
