Description

The utility model relates to the production of building materials, in particular to the production of silicate brick.

The technology for heat treatment of raw silicate brick requires stacking it in a stack consisting of four walls with a thickness of one brick with an oval contour of the upper part. This leads to the fact that the upper layers of the walls contain the number of bricks, decreasing as the layer approaches the top of the stack. The specific number of bricks in each layer is determined by the stacking map. The more the upper part of the stack from the pyramidal shape approaches the oval, the more bricks can be placed in the stack, the unacceptable configuration of the stack causes a sharp decrease in the utilization of the volume of the autoclave.

A known complex for forming and stacking silicate brick, containing a revolving press, with each turn of the table which is pushed two bricks, and a conveyor synchronized with the work of the revolving press; a puller that ensures the transfer of bricks from the press to the conveyor; and a stacker, providing the transfer of brick from the conveyor to the parking trolley (see Rozin KB, Automatic machines-stackers of silicate brick - M .: TSNIITEStrom of the Ministry of the industry of building materials, 1969. - p.17-18).

In the process, a puller connected to the crankshaft of the press removes 4 bricks from the press table and transfers them to the conveyor.

Since at each turn of the press table only 2 bricks are pushed out, removal is carried out after every second turn. During the transfer to the conveyor, the bricks, making a complex movement, are deployed by the gripper-manipulators of the puller in one line and from

the positions on the die come into position on the rib. They are installed on the conveyor constantly in the same position point to point with a certain gap. When the puller returns to the press after the next group of 4 bricks, the conveyor moves a step equal to the thickness of the brick, increased by a small gap. After repeated repetition of these operations on the conveyor, the number of rows of bricks is accumulated, necessary for the formation of a complete layer on the trolley. After that, the stacker, having captured the bricks of the formed complete layer, comes into motion along the conveyor, transferring the entire layer to a trolley installed with the ability to move perpendicular to the conveyor. To give the stack the desired oval configuration, the stacker travel is changed.

The disadvantage of this complex is that its constructive implementation is oriented to work with a low-power turret press. The low operational capacity of the press (at each turn of the table only two bricks are pushed out), the removal of bricks from the press only after every second turn of the press table and the formation of a layer of bricks on the conveyor along one line in one stroke of the puller cause low productivity of the complex.

The closest in technical essence, the achieved result and selected as a prototype is a complex for forming and stacking silicate bricks, including a press, in the table of which there is a group mold with nests for bricks; a conveyor located along the axis of the supply of bricks from the press; parking trolley; a puller that ensures the transfer of brick through a window in the front of the press to the conveyor; and a stacker for transferring bricks from the conveyor to the parking trolley. The mold seats of the press table are placed so that their longitudinal walls are parallel to the conveyor. The parking trolley and the puller are placed with the possibility of movement along the conveyor, and the stacker with the possibility of

moving across it (see L.M. Khavkin Silicate brick technology - M .: Stroyizdat, 1982. - p.222, Fig. V-1.25 Press of Sutcliff & Speakman S-S 500).

This arrangement of the complex involves the transfer of bricks issued by the press through a window in the front of the press due to simple movement (without changing the position of the brick during the transfer, which takes place in the prototype described above), the puller in a straight line along the axis of the conveyor. For one cycle of the press, two rows of bricks, several (usually 8 pieces) pieces in each, are simultaneously pushed onto its table. These bricks are simultaneously carried out by the stripper on the conveyor. During a repeated press cycle, the puller transfers two more rows of bricks to the conveyor, i.e. on the conveyor a group of bricks is formed in four rows of 8 bricks in each. Of these groups, a stacker of four walls is formed on a parking trolley using a stacker that moves perpendicular to the axis of the conveyor. Since the length of the group (8 pieces of bricks) is insufficient for the formation of a full layer of the stack on the parking trolley, it is formed of several groups (the lower part of the stack from 2-3 groups, the upper - from 1-2 groups) in several moves of the stacker.

It is obvious that, providing greater productivity in comparison with the above complex, this complex allows you to form a stack in the shape of a pyramid with large ledges. The size of the ledge is determined by the number of bricks in the rows forming the group.

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

The objective of this utility model is to improve the configuration of the top of the stack.

The technical result obtained by the implementation of this utility model is the possibility of forming on the conveyor a complete layer for the trolley.

This problem is solved due to the fact that in the known complex for molding and stacking raw silicate brick, containing a press, in the table of which a group mold with nests for bricks is placed; a conveyor located along the axis of the supply of bricks from the press; parking trolley; a puller installed with the possibility of moving along the conveyor, which ensures the transfer of bricks from the press to the conveyor; and the stacker, providing the transfer of the brick from the conveyor to the parking trolley, according to the utility model, the longitudinal walls of the mold seats and the path along which the parking trolley is mounted movably are placed perpendicular to the conveyor, while the mold slots are arranged in four rows, which parallel to the conveyor, and in each row there are two, five nests.

Studies conducted on the sources of patent and scientific and technical information showed that the claimed complex is unknown, i.e. meets the criterion of novelty.

The complex can be manufactured at any enterprise specializing in this industry, as this requires well-known materials and standard equipment, and is widely used in the production of silicate brick, i.e. is industrially applicable.

The implementation of the complex in the claimed form allows you to get bricks oriented from the conveyor and the trolley from the press so that in one move the stacker can take away from the conveyor and move a group of bricks to the trolley, the length of which is equal to the length of the full layer on the trolley.

When placing nests in four rows, the press gives bricks to the conveyor for one cycle of work to form four walls at once on a parking trolley. The increase in the number of nests in a row allows you to quickly accumulate enough bricks on the conveyor to form a full layer of stacks on the trolley.

Thus, it is obvious that the proposed layout of the complex provides the formation of a stack with an oval shape of the upper part.

The utility model is illustrated by drawings, on which are presented:

The complex for molding and stacking raw silicate brick contains a hydraulic press 1, in the table of which there is a group mold 2 with slots 3 for bricks 4. A conveyor 5 is located along the feed axis of bricks 4 from press 1. The complex also includes a parking trolley 6 mounted on rail 7, mounted with the possibility of movement along the conveyor 5, the puller 8, which ensures the transfer of bricks from the press 1 to the conveyor 5, as well as a stacker 9, which provides the supply of bricks 4 to the parking trolley 6. Longitudinal walls nests 3 of the mold 2 and the path 7, on which the parking trolley is mounted with the possibility of movement, are placed parallel to each other and perpendicular to the conveyor 5. The stacker 9 can be installed with the possibility of moving along and across the conveyor 5 or with the possibility of moving only along the conveyor 5. In the first case, the trolley is placed on the side of the conveyor 5, in the second case, the trolley 6 is placed at the end of the conveyor5. The nests 3 of the mold 2 are arranged in four rows parallel to the conveyor 5. Each row has 2, 3, 4, or 5 nests (depending on the required operational performance of the complex). Compact place

on the press table 1, a large number of nests 3 of the mold 2 allows the orientation of the nests 3 with the long side along the long side of the press table 1.

The complex works as follows.

The mold of the press table 1 is filled with the molding mixture with the aid of a moving hopper of the mixture over the mold (not shown). After the molding cycle, press 1 pushes a group of bricks 4 from the mold 2, located on the long side along the length of the press table 1 and perpendicular to the conveyor 5. The group of bricks 4 includes four rows, each of which consists of 2-5 pieces. The puller 8, connected to the press 1, immediately removes all the bricks of the 4 groups from the press table 1, clamping them with grippers for pokes, and when moving them rallies them, placing them with the same gap between them. The axis of supply of bricks 4 by puller 8 from press 1 coincides with the longitudinal axis of conveyor 5. Bricks 4 are installed by puller 8 on conveyor 5, which serves as a drive. Grips release bricks 4, and puller 8 returns for a re-cycle. When the puller 8 is returned to the press 1 after the next group of bricks 4, the conveyor 5 moves by a step equal to the length of the group, increased by a small guarantee gap. After 2-3 cycles, the number of rows of bricks 4 is accumulated on the conveyor 5, which is necessary for a complete layer on the trolley 6, and these rows include four bricks 4, which allows you to form four stacked walls on the trolley 6. By moving the stacker 9 the stacker 9 is installed along the conveyor 5 in such a position that it grabs the full layer for the trolley 6. Then, if the trolley 6 is placed on the side of the conveyor 5, the stacker 9 is moved first along the conveyor 5 (so that it stands up By contrast trolley 6) and then transversely of the conveyor 5 and sets it on the complete layer zaparochnuyu trolley 6. In case of placing trolley 6 at the end of the conveyor 5, stacker 9

move only along the conveyor 5 when transferring the full layer to the trolley 6. During the movement of the stacker 9 to the trolley 6, a new group of bricks 4 is formed on the conveyor 5. From this group, the stacker 9 selects a new next full layer for the trolley 6. Moreover, the number of rows of bricks 4 in a layer depends on the position of the layer in the stack.

Thus, the claimed complex, providing the formation of a stack of full layers, allows for the formation of a stack with an oval shape of the upper part.
