The invention relates to the production of building materials, in particular the production of silica brick.

Technology for heat treatment of silica bricks requires stacking, consisting of four walls with a thickness of one brick with oval contour of the upper part. This leads to the fact that the upper layers of the walls contain the number of the bricks, decreasing the closer the layer to the top of the pile. The exact number of bricks in each layer defines a map laying of the pile. The more the upper part of the pile from pyramidal approaches oval, the greater the number of bricks can be placed in the stack, unacceptable configuration of the stack causes a sharp reduction in the utilization volume of the autoclave.

A known system for forming and stacking silica brick containing turret press at every turn table which is pushed by two bricks, and are synchronized with the turret press conveyor; a stripper for the transmission of brick from the press to the conveyor; and shtabelirovshchiki for the transmission of bricks from the conveyor to the hardening of the trolley (see Rozin K.B. Machines-stabilnosti silicate brick., M, Createstream of the Ministry of industry of building materials, 1969, p.17-18).

In the process of working with the MSC, connected to the crankshaft of the press, removes from the table press four brick and transfers them to the conveyor. Because at every turn table press is popped just two bricks, eat is carried out after every second turn. While moving on the conveyor bricks, making complex movement, unfolding grips the arms of a stripper in one line and from plashes come into position on the edge. They are installed on the conveyor continuously in the same position jab for jab with a certain gap. When the stripper is returned to the press for the next group of four bricks, the conveyor moves a step equal to the thickness of the brick, increased by a small gap. After multiple repetition of these operations on the conveyor dialed the number of rows of bricks needed for the formation of a complete layer on the trolley. Then shtabelirovshchiki, capturing the bricks formed a complete layer moves along the conveyor, transferring the entire layer on a trolley mounted for movement perpendicular to the conveyor. To make the stack of the desired oval configuration stroke of shtabelirovshchiki changes.

The disadvantage of this complex is that its design execution is focused on working with small turret press. A small operation the ion capacity of the press (at each turn table is popped only two bricks), the implementation of the removal of the brick with the press only after each of the second turn-table of the press and the formation of a layer of bricks on the conveyor in a single row in one turn puller cause of low performance of the complex.

The closest to the technical essence and the achieved result and selected as a prototype is a system for forming and stacking of silicate bricks, including the press, in the table which is placed group mold with nests under the bricks; a conveyor located along the axis of the supply of bricks from the press; hardening the cart; a stripper for the transmission of a brick through a window in the front of the press to the conveyor; and shtabelirovshchiki for the transmission of bricks from the conveyor to the hardening of the trolley. Nest molds of the press table are arranged so that their longitudinal walls parallel to the conveyor. The hardening trolley and the puller is placed can be moved along the conveyor, and shtabelirovshchiki - can travel across it (see Lamken. Technology of silicate bricks. - M.: stroiizdat, 1982, p.222, .V-1.25. Press firm "Sutcliffe and Spikman" S-S 500).

Such an arrangement is complex involves moving bricks, issued by the press, through the window in the front of the press at the expense of simple movements (without changing the position of the brick when moving with months is about in the above prototype) of a stripper in a straight line along the axis of the conveyor. For one cycle of press operation on his table at the same time popped two rows of bricks on several (usually 8 pieces) pieces each. These bricks simultaneously submitted puller on the conveyor. When re-cycle press the stripper moves on the conveyor even two rows of bricks, i.e. on the conveyor is formed group of bricks of four rows by eight bricks each. Of these groups on the hardening of the trolley with the help of shtabelirovshchiki, which moves perpendicular to the axis of the conveyor is formed by a stack of four walls. Because the length of the group (8 bricks) is insufficient for the formation of a complete layer stack on the hardening of the trolley, it is formed of several groups (the lower part of the pile of 2-3 groups, top with 1-2 groups) in a few moves of shtabelirovshchiki.

Obviously, providing greater performance compared to the above complex, this complex allows to form a stack having the shape of a pyramid with large ledges. The size of the shelf is determined by the number of bricks in the rows that make up the group.

Thus, the disadvantage of the prototype is unacceptable configuration of the upper part of the pile which instead of the desired oval has a pyramidal shape.

The present invention is to improve the configuration of the top of the stack.

Technical achiev what tatom, the resulting implementation of this invention is the formation on the conveyor full layer for the trolley.

This problem is solved due to the fact that in the known system for forming and stacking of silicate brick, containing press, in the table which is placed group mold with nests under the bricks; a conveyor located along the axis of the supply of bricks from the press; hardening the cart; mounted for movement along the conveyor puller for the transmission of brick from the press to the conveyor; and shtabelirovshchiki for the transmission of bricks from the conveyor to the hardening of the trolley according to the invention the longitudinal walls of the slots of the mold and the way in which they can move installed hardening trolley, placed perpendicular to the conveyor while nest molds are placed in four rows, which are parallel to the conveyor, and in each row, placed on two to five nests.

Research conducted on the sources of patent and scientific and technical information, showed that the proposed complex is unknown and should not be explicitly studied the prior art, i.e. meets the criteria of "novelty" and "inventive step".

The complex can be produced in any enterprise, specializing in this industry, because this is about requires known materials and standard equipment and widely used in the manufacture of silica brick, i.e. is industrially applicable.

The complex in the present form allows you to get from the press of the bricks are oriented relative to the conveyor and the hardening of the trolley so that in one move, shtabelirovshchiki can take away from the conveyor and move on hardening the cart group of bricks, the length of which is equal to the length of the full layer on the trolley.

When placing nests in four series of press for one cycle of operation produces on the conveyor bricks for the formation of the four walls of the hardening of the trolley. The increase in the number of nests in a row faster to accumulate on the conveyor, the number of bricks, enough to form a full layer stack on a trolley.

Thus, it is obvious that the proposed layout of the complex provides for the formation of the pile with the oval shape of the upper part.

The invention is illustrated by drawings, on which:

Figure 1. Complex, General view (the dashed line shows the position of the trolley when the movement of shtabelirovshchiki along the pipeline).

Figure 2. Mold table press, top view.

Figure 3. View along a-a in figure 1.

System for forming and stacking of silicate bricks contains hydraulic press 1, in the table which is placed group mold 2 with the slots 3 bricks 4. On ocypode bricks 4 of the press 1 is the conveyor 5. The complex also includes hardening the trolley 6, mounted on a rail 7 mounted for movement along the conveyor 5 puller 8 for the transmission of brick from npecca 1 to the conveyor 5, as well as shtabelirovshchiki 9 providing bricks 4 to the hardening of the trolley 6. The longitudinal walls of the slots 3 of the mold 2 and the path 7, which can move installed hardening trolley 6, placed parallel to each other and perpendicular to the conveyor 5. Shtabelirovshchiki 9 may be mounted for movement along and across the conveyor 5 or can move only along the conveyor 5. In the first case, the trolley 6 is placed at the side of the conveyor 5, in the second case, the trolley 6 is placed at the end of the conveyor 5. Socket 3 of the mold 2 is placed in four rows parallel to the conveyor 5. In each row, placed at 2, 3, 4 or 5 slots (depending on the desired operational performance of the complex). Compactly placed on the press table 1 a large number of sockets 3 of the mold 2 allows the orientation of the slots 3 with the long side along the long side of the table npecca 1.

The complex operates as follows.

Press form press table 1 is filled with sand by means of moving the reciprocating over the press hopper shape mixture (not shown). Politicla molding press 1 out of the mold 2 a group of bricks 4, located with the long side along the length of the table, press 1 and perpendicular to the conveyor 5. The group of bricks 4 includes four rows, each of which consists of 2-5 pieces. The stripper 8, connected to a pressure of 1, removes from the table, press 1 once all the bricks are 4 groups, clamping their holds and blows, and when the transfer unites them, with equal space between them. The axis of the feed bricks 4 the stripper 8 press 1 coincides with the longitudinal axis of the conveyor 5. Bricks 4 are set puller 8 on the conveyor 5, performs the function of the drive. Grips free bricks 4 and the stripper 8 is returned for re-cycle. When returning the stripper 8 to press 1 for the next group of bricks 4 the conveyor 5 moves a step equal to the length of the group increased by a small guarantee clearance. After 2-3 cycles on the conveyor 5 is dialed this number of rows of bricks 4 what you need to complete the hardening layer on the trolley 6, and these lines include four bricks 4 that allows you to create four walls, stacking on trolley 6. By moving shtabelirovshchiki 9 along the conveyor 5 install shtabelirovshchiki 9 in such a position that provides a capture layer for full trolley 6. Then, if the trolley 6 at the side of the conveyor 5, shtabelirovshchiki 9 move along the first conveyor 5, so he stood up in front of you is goneski 6), and then across the conveyor 5 and he sets complete the hardening layer on the trolley 6. If the trolley 6 at the end of the conveyor 5, shtabelirovshchiki 9 move only along the conveyor 5 when the transfer complete the hardening layer on the trolley 6. During the movement of shtabelirovshchiki 9 to the trolley 6 on the conveyor 5 is formed a new group of bricks 4. From this group shtabelirovshchiki 9 selects a new regular full layer for trolley 6. Moreover, the number of rows of bricks 4 in the layer depends on the position of the layer in the stack.

Thus, the claimed complex, generating stacks of full layers, allows to ensure the formation of the pile with the oval shape of the upper part.
