SU823143A1 - Device for placing frames with raw bricks onto multishelf cars - Google Patents

Description

t.

The invention relates to the building materials industry, and more specifically to devices for laying raw bricks on trolleys of drying tunnels.

A device for laying bricks with bricks on trolleys is known, comprising a mechanism for moving frames, a hoist drive, a mechanism for transferring a package of frames from a hopper to a trolley fl. .

It is also known a device for laying frames with bricks on shelf trolleys, comprising a receiving roller table, a frame feeder conveyor in the form of a horizontal stepping conveyor, a frame accumulator mounted on a carriage moved along vertical directions kmtsm and their electric drives 2.

A disadvantage of the known devices is the large metal consumption, due to the large capacity of the accumulator, which is used to form the entire pack of crayfish, which is then reloaded onto the trolley with one trick. The device is intermittent in nature of work, which is caused by the fact that while the drive transfers the frame packet to the trolley, the frame movement mechanism is idle. Working like a device operating in a continuous process technology reduces the performance of both the device itself and the entire process line.

The purpose of the invention is to reduce the metal content and increase the performance of the device due to

0 fo4) unwrap the frame package directly on the trolley.

This is achieved by the fact that the drive is made in the form of a horizontal stepping conveyor mounted on the carriage, the conveyor-feeder; CONSOLIDATELY to another carriage moved by the P9 vertical guides,

0 and the conveyors are located with the mutual overlap of the bearing surfaces along the length in the working position, while the drive shafts of both conveyors are connected to their

5 electric drives through bevel gears. drive gears which are mounted on vertical shafts installed with the possibility of sliding inside the drive pulleys

0 electric drives. . .i

FIG. 1 shows the proposed device, side view; in fig. 2, section A-A in FIG. one.

The device contains a receiving roller conveyor 1, an emphasis 2, a transporter of frames 3 with two endless chains 4 mounted on guides 5, which are cantileverly mounted on a roller carriage 6, vertically moving along the guides 7 by means of electric drive 8, belt transfer 9 and two parallel chain transmissions 10, the chain of each of which is closed on the carriage b. The chains 4 of the conveyor 3 are driven by driving sprockets 11 connected to a stepper motor 12 by means of a shaft 13 having the possibility of vertical movement inside the pulley 14 and a bevel gear 15 mounted on shafts 13 and 16.

The design of the conveyor-drive 17 comprises endless chains 18, guides-19, a carriage 20 moving along the guides 21 by means of the electric drive 22 and gears 23 and 24. The drive sprockets 25 are connected with the stepper electric drive 26 by means of bevel gears 27 and 28 mounted on shafts 29, 30, 31. The starting conveyor 17 covers (overlaps the end of the conveyor-feeder 3 by a distance equal to the width of the frame 32 with a brick.

The brick frames 32 are laid on the loading trolley 33 with the shelves 34. The trolley 33 is inserted into the operating zone of the conveyor 17, the corresponding part of which has a height less than the distance between the lower shelves and the base of the trolley.

Chain drives 4, 10, 18, and 24 are equipped with a device for tensioning the chains (not shown in the drawings).

The actuators 8, 12, 22 and 26 are connected to an electrical control system providing a predetermined sequence of switching on the actuators using contactless limit switches (not shown in the drawings).

The device works as follows.

In the initial position, the conveyor belt 3 is on the same level with the receiving roller table 1, and the conveyor belt drive 17 is 10–15 mm higher than the upper shelves 34 of the loaded truck 33. The frame 32 with bricks is fed to the receiving roller table and rests on the stop 2. The electric drive 8 is activated and the conveyor 3, with the frame 32, rises 10-15 mm. above the conveyor 17. The stepper motor 12 is turned on and with the help of the chains 4 feathers moves the frame one step towards the conveyor 17. The step length is equal to the width of the frame and the gap between two adjacent frames. The conveyor 3 is lowered back to its original position, and the frame remains on the conveyor 17, which with the help of the stepper motor-26 and the chains 18 moves it one step towards the trolley. Then, in the same order, the next frame enters the conveyor 17 and both frames again move one step. After entering the conveyor

17 of the frame required to fill one row of shelves

18 move the frames further in several steps, for example three, and set the frames above the shelves of the trolley. The actuator 22 is turned on and the conveyor 17 is lowered. The frames remain in the upper shelves of the trolley. In the same way, the second and subsequent rows of pgmok are laid on the trolley.

When laying the frames on the shelves located below, the conveyor 3 first moves the frame one step towards the conveyor 17, and then lowers it onto the conveyor 17, which moves the frame one step towards the trolley, after which the conveyor 3 returns to its original position.

After filling the lower shelves, the trolley is taken out of the operating zone of the conveyor 17, after which it is raised, returns to. initial position.

The laying of the frames by the conveyor 3 on the conveyor 17 during the period of the trolley leaving and returning the conveyor 17 to the initial position is not interrupted, while the conveyor 17 performs the function of a frame accumulator.

When the conveyor 17 returns to its initial position, an empty trolley is introduced into its area of operation, the frames on the conveyor 17 are reloaded onto the shelves, then the loading cycle is repeated.

The proposed device in comparison with the known has a lower metal consumption, and its productivity is higher.
