System for forming and stacking raw calcium-silicate bricks 1. Technical sphere The invention is related to construction materials production, calcium-silicate bricks production in particular. 2. Preceding technical level The technology of raw calcium-silicate bricks heat treatment requires its block stowage (stacking) consisting of four walls one brick thick with an oval contour of the top part. It results in the top layers containing the amount of bricks that is decreasing while getting closer to the top of the stack. The specific amount of bricks in each layer is determined by the plan of stacking. The more the top part of the stack resembles an oval and the less it resembles a pyramid, the greater amount of bricks can be stowed in one stack. Unacceptable stack configuration causes a drastic decrease of the autoclave volume utilization coefficient. There is a system for forming and stacking raw calcium-silicate bricks that is well- known. It contains a press provided with a bed in which a multiple mould with cavities for bricks is arranged, a conveyor line, a steaming wagon, a puller transferring the bricks from the press to the conveyor and a stacking device transferring the bricks from the conveyor to the steaming wagon. The conveyor line is arranged perpendicularly to the bricks transport axis from the press. The cavities of the multiple mould are arranged in such a way that they form two parallel lines with 8 cavities in each, and these lines are perpendicular to the conveyor line. The longitudinal walls of the cavities in those lines are parallel to the conveyor line. The steaming wagon is arranged in such a way that it is movable along the conveyor. The puller and the stacking device are installed with a possibility of moving across the conveyor line (see booklet of the company "LASCO Umformtechnik GmbH Partner on the introduction of an efficient calcium-silicate brick production technology», 2001). Such an assembling of the system requires a simultaneous transportation by the puller of two lines of bricks with 8 pieces in each that are produced by the press. The bricks are transported by the puller through a window in the side-frame of the press onto the conveyor line that is perpendicular to the bricks transport axis from the press. During the recurring cycle of the press the puller transports two more lines with 8 bricks in each onto the conveyor line. Thus, a group of 4 lines with 8 bricks in each is formed on the conveyor. A stack with 4 walls of one brick thick is formed from those groups on the steaming wagon with the help of the stacking device. As the length of one group (which is 8 bricks) is not sufficient for forming a full layer of a stack, it is formed from several groups (the lower part of the stack is formed from 2-3 groups, and the upper part is formed from 1-2 groups) in several trips of the stacking device. It is obvious that low productivity is a shortcoming of that system. It is conditioned by the fact that individual devices of the system during their working process manipulate a small amount of bricks simultaneously. There is a system for forming and stacking raw calcium-silicate bricks that is the closest in technical essence and achieved result, it was chosen as a prototype. That system comprises a press provided with a bed in which a multiple mould with cavities for bricks is arranged, a conveyor line disposed along a bricks transport axis from the press, a steaming wagon, a puller providing bricks transportation through a window in the face side of the press to the conveyor line, and a stacking device providing bricks transportation from the conveyor line to the steaming wagon. The mould cavities of the press bed are arranged in such a way that their longitudinal walls are parallel to the conveyor. The steaming wagon and the puller are arranged in such a way that they are movable along the conveyor, and the stacking device is installed with a possibility of moving across the conveyor line (see the book by L.M. Khavkin "Technology of silicate brick", Moscow, printed by "Stroiizdat", 1982, page 222, figure V - 1.25. The press of the company "Satcliff and Speakman" S-S 500). Such an assembling of the system requires transportation of the bricks produced by the press through the window in the face side of the press along the conveyor line. It changes the trajectory of bricks moving from the press to the steaming wagon. In this case, the puller moves along the conveyor line. However, such a big drawback of the assembling as forming a full layer from different groups on the steaming wagon is retained. It is explained by the fact that it is impossible to place the sufficient amount of bricks for forming a full layer across the conveyor line. Increasing the quantity of bricks in lines that are produced by the press at once causes increasing the group's length, which leads to forming big ledges in the stack contour. It does not allow to increase the system's productivity. * 3. Invention revealing The primary goal of this invention is to increase the system's labour productivity by providing an opportunity of manipulating large groups of bricks. The said goal is achieved using a well-known system for forming, and stacking raw calcium-silicate bricks that comprises a press provided with a bed in which a multiple mould with cavities for bricks is arranged, a conveyor line disposed along a bricks transport axis from the press, a steaming wagon, a puller arranged in such a way that it is movable along the conveyor, providing bricks transportation from the press to the conveyor line, and a •stacking device providing bricks transportation from the conveyor line to the steaming wagon. According to this invention, the longitudinal walls of the multiple mould cavities and a path, on which a stacking device is installed with a possibility of moving, are arranged perpendicularly to the conveyor line, and the cavities of the multiple mould are arranged in four rows that are parallel to the conveyor line, each row comprising at least six cavities. Research work made with the help of patent and scientific-technical information showed that the presented system is unknown and does not come directly from the investigated technological level, i.e. it meets the criteria "novelty" and "inventive level". The system implementation in the presented way allows getting bricks from the press oriented concerning the conveyor line and the steaming wagon in such a way that at once the stacking device is able to take from the conveyor line and place onto the steaming wagon a group of bricks, the length of which is equal to the length of one layer on the steaming wagon. Under the condition of arranging the cavities in four rows, during one working cycle the press produces onto the conveyor the amount of bricks enough for forming four walls on the steaming wagon at once. An increase of the amount of cavities in one row allows collecting enough bricks for forming a full layer of the stack on the steaming wagon more quickly. Therefore, it is obvious that the suggested assembling of the system provides an increase of labour productivity. 4. A brief description of the working drafts' figures The invention is explained by figures where the following is presented: Figure 1 The system, general view (the placement of the steaming wagon during the stacking device's moving along the conveyor line is shown by dotted line) Figure 2 Multiple mould of the press bed, view from above Figure 3 View of A-A on Figure 1 5. The best variant of the invention implementation The system for forming and stacking raw calcium-silicate bricks comprises a hydraulic press (1) provided with a bed in which a multiple mould (2) with cavities (3) for bricks (4) is arranged. A conveyor line (5) is situated along the brick transport axis (4) from the press (1). The system also contains a steaming wagon (6) placed on a track path (7), a puller (8) which is arranged in such a way that it is movable along the conveyor line (5) and transfers the bricks (4) from the press to the conveyor (5), and a stacking device (9) transferring the bricks (4) from the conveyor (5) to the steaming wagon (6). The longitudinal walls of the multiple mould (2) cavities (3) and a path (7), on which the movable steaming wagon (6) is disposed, are arranged in parallel to each other and perpendicularly with respect to the conveyor line (5). The stacking device (9) can be installed with a possibility of moving along and across the conveyor line (5) or with a possibility of moving only along the conveyor line (5). In the first case the steaming wagon (6) is placed at the side of the conveyor line (5), and in the second case the steaming wagon (6) is situated at the end of the conveyor line (5). The cavities (3) of the mould (2) are arranged in four rows which are parallel to the conveyor (5). Each row comprises six (or more) cavities (3). Compact arrangement of a large amount of mould cavities (3) in the press bed (1) is possible due to the cavities' (3) placement by their long side along the press bed (1) long side. Such a placement of the cavities (3) allows arranging four rows each containing 6-10 cavities (3), which provides production of 24-40 bricks (4) during one cycle of the press work. The system works as follows. The multiple mould of the press bed (1) is tilled with agglutinant sand with the help of 'a mixture bunker moving back-and-forth above the multiple mould (the bunker is shown on the working draft). After the moulding cycle the press (1) ejects from the multiple mould (2) a group of bricks (4) arranged with their long sides along the press bed (1) longitude and perpendicular to the conveyor line (5). A group of bricks (4) comprises four rows, each of them contains 6-10 bricks. The puller (8) connected with the press (1) withdraws from the press bed (1) all the bricks (4) of the group at once, gripping them with claws by headers. It joins them while carrying and arranges them with equal space between each brick. Brick transport axis (4) by the puller (8) from the press (1) coincides with the longitudinal axis of the conveyor line (5). The bricks are placed on the conveyor line (5) by the puller (8) that fulfills the function of a storage device. The claws free the bricks (4), and the puller (8) goes back for the next cycle. When the puller (8) comes back to the press (1) for the next group of bricks (4), the conveyor line (5) moves by one step which is equal to the length of the group plus a little warranty gap. After 2-3 cycles the conveyor (5) stores the amount of brick lines enough for forming a full layer on the steaming wagon (6). Those lines, at the same time, contain four bricks (4), which allows forming four walls of a stack on the steaming wagon (6) at once. Due to the stacking device's (9) moving along the conveyor line (5) the device is installed in such a position that provides gripping of a full layer for the steaming wagon (6). Then, if the steaming wagon (6) is arranged at the side of the conveyor line (5), the stacking device (9) is moved across the conveyor line (5), and it places a full layer onto the steaming wagon (6). In case of the steaming wagon (6) arrangement at the end of the conveyor line (5), the stacking device (9) is moved only along the conveyor line (5) for transferring a full layer onto the steaming wagon (6). While the stacking device (9) is moving to the steaming wagon (6), a new group of bricks (4) is produced on the conveyor (5). The stacking device (9) picks the next layer for the steaming wagon (6) from that group. The amount of brick lines (4) in a group depends on the layer's position in the stack. Therefore, the presented system allows drastic increasing of the system's labour productivity and providing forming a stack with an oval shape of the top part. At the same time, the system provides forming a stack from complete layers which are quickly accumulated on the conveyor line due to a large amount of bricks produced by the press at once. 6.
