A guide 34 having a through hole 33 capable of accommodating 32 is provided.

Further, in order to carry out the brick stacking more efficiently, two or more sets of devices having the construction shown in FIG. 3 may be arranged in each block on the input side, the intermediate side and the output side.

Next, a modified embodiment of FIG. 3 will be described with reference to FIG. The transfer system in Fig. 3 requires 6 steps per cycle from (a) to (g). Fig. 8 (a) shows the brick transfer capability improved by shortening this to 4 steps.
It is the transport system shown in (e). The brick guide of FIG. 3 is a tubular shape with four sides completely enclosed, while the brick guide of FIG. The slit 19a is formed so that the rod of the cylinder can pass through.

The manner of conveying the bricks in a stepwise manner is the same as that in the case of FIG. 3, but the manner in which the steps are shortened will be explained together with the configuration thereof with reference to FIGS. 8 (a) to 8 (e). (a): Shows a state in which the brick 28 has already been incorporated into the first-stage brick guide 16. The brick 28 taken in is a supporting member 17 provided at the rod end of a fluid pressure cylinder (hereinafter referred to as an ascending / descending fluid pressure cylinder) 17 that constitutes the first stage lifting device.
It is listed on a. (b): When the rod of the lifting hydraulic cylinder 17 in the first stage is extended, the brick 28 is pushed up into the brick guide 19A in the second stage connected directly above the brick guide 16 in the first stage. (c): The second-stage brick guide 19A is horizontally swiveled around the swivel center O by a driving means (not shown), and the supporting member 18a of the second-stage up-and-down fluid pressure cylinder 18 (see (b) figure) Reprinted in. Reference numeral b is a fan-shaped transfer guide that bridges between the support members. (d): The rod of the fluid hydraulic cylinder 18 of the second stage is extended to push the brick 28 up to the brick guide 20 of the third stage. At the same time, the rod of the lifting hydraulic cylinder 17 of the first stage is retracted. (FIGS. 3 (a) to (d) are the same as FIGS. 8 (a) to (d)) At this time, the one side wall 16a of the brick guide 16 of the first stage is used as a tilting cylinder with the hinge at the lower end as a spindle. 16
Prepare to take in the next brick by tilting with b.

(E): O centered on the brick guide 20 on the third stage
It swivels around and is transferred onto the support member 23a of the third-stage ascending / descending fluid pressure cylinder 23. At the same time, the second-stage brick guide 19 is swung in the opposite direction to the center O while the rod of the second-stage ascending / descending fluid pressure cylinder 18 is extended. At this time, a slit 19a vertically provided on one side wall of the brick guide 19A allows the rod to pass therethrough. By this operation, the second-stage brick guide 19A is returned to a position directly above the first-stage brick guide 16. At the same time, the brick is received from the tilted side wall 16a of the first-stage brick guide 16 and the tilting cylinder 16b is operated to operate the side wall 16a.
Brick guide 1 that was raised up to the original position and returned.
Incorporate brick 28 'into 6.

In this way, the second-stage brick guide 19A
Since a slit 19a is formed on one side wall 16a of the lifting / lowering fluid pressure cylinder 18 so that the rod of the lifting / lowering fluid pressure cylinder 18 can pass therethrough. The brick guide 19A can be returned to the original position, and this operation can be performed at the same time as the operation of transferring the brick guide 20 to the third stage. Therefore, as compared with the case of the embodiment of FIG. When there is no slit, as shown in (e)-(f)-(g) of FIG. 3, first, the rod of the second-stage ascending / descending fluid pressure cylinder 18 is shortened, and then the second-stage brick guide 19 is replaced. It can be reduced by two steps (because it needs to be returned to the position). In other words, although the transfer steps from (a) to (d) of FIG. 3 are the same, the steps of (e)-(f)-(g) of FIG. 3 are the same as those of FIG. 8 (e).
Is integrated into the process. With 6 steps per cycle, the brick transfer capacity is limited to 300 pieces per hour, but with 4 steps, the capacity can be increased to 400 pieces. The rod of the second-stage lifting / lowering fluid pressure cylinder 18 may be shortened when pushing up the brick 28 'in the first-stage brick guide 16. Carry the bricks to a predetermined position by sequentially performing the above operation,
Use the brick guide at the top to take out and stack at the designated position in the furnace. FIG. 9 shows a modification of FIG. Similar to the embodiment of FIGS. 3 and 8, the lowermost stage is provided with a first-stage brick guide 16 equipped with a brick intake device and a brick elevating device 17, and a horizontal direction immediately above the first-stage brick guide 16. It is equipped with a second-stage brick guide 19B that can be shifted. Then, the third-stage brick guide 20 which can be laterally shifted is provided above the second-stage brick guide 19B in a stepwise manner,
Similarly, in general, a brick guide in the n + 1-th stage that can be laterally shifted is provided above the n-th stage brick guide in a stepwise manner, and the brick guide in the brick guide after the shift to the second-stage and subsequent brick guides. A brick elevating device for elevating and lowering the bricks is provided, and a brick guide 27 having a brick dispensing device is provided at the uppermost stage. However, in the embodiment of FIG. 9, although the brick guides before shifting and the brick lifting devices are arranged in a staircase, strictly speaking, in this case, they are arranged in a zigzag staircase. The bricks are elevated and transported in a zigzag staircase.

The brick lifting device in this case is also shown in FIG.
As shown in the sectional views of 0 (a) and (b), a slit 19b is provided in the vertical direction on one side surface of the second-stage brick guide 19B. The brick guide 19 is inserted through the slit 19b.
A support member 18b having a rectangular support plate 18f housed in a brick guide 19B, which projects into B, is attached to the second-stage lifting device 18A. This lifting device 18A
Is composed of an endless belt 18e that is stretched between upper and lower pulleys 18c and 18d as shown in FIG. 9. By driving one of the pulleys to move the belt 18e up and down, the support member 18b is placed between the slits 19b. Is configured to move up and down. Such a configuration is the same for the third and fourth lifting devices 23A and 24A and the brick guides 20 and 25. Thus, when the supporting plate 18f of the lifting device 18A is at the upper limit or the lower limit because the slits 19b are provided on the side surface of the brick guide 19b (FIG. 10 (b)), the brick guide 1
The fact that 9B can be shifted in the lateral direction is the same as in the embodiment of FIG.

The brick transfer process is shown in FIGS. 9 (a) to 9 (e). This is different from the case of FIG. 8 in the brick elevating device and the transfer mode (the brick is raised in a zigzag shape).
Since the procedure is the same, the description is omitted. In the figure, 27 indicates the uppermost brick guide.

Numerals 21, 22, and 26 are fluid pressure cylinders for shifting the second to fourth brick guides, and the brick guides are laterally shifted so that the supporting plate 1 of the elevating device at the same stage.
Brick is transferred on 8f.

In the case of the embodiment shown in FIG. 3, one brick is used.
Since three blocks are involved in raising the stage (for example, the input block and two intermediate blocks are involved in the state of Fig. 3 (d)), high precision machining is required to reduce the error of each block. However, in the case of the embodiment of FIG.
Only two blocks are involved to raise the brick one step, and there is an advantage that the processing accuracy of each block can be relaxed. Further, the number of steps in one cycle is the same as that in the embodiment of FIG.

It is also possible to use a screw-shaped brick feeding device as shown in FIG. 11 as a brick stacking means instead of the fluid pressure cylinder which controls the lifting device. Next, FIG. 11 will be described. In the figure, 35 is a brick, 36 is a brick-incorporating device with a U-shaped cross-section that can be tilted in the direction of the arrow, 3
7 is a brick feed screw, 38 is a feed screw drive motor, 39
Is a drive transmission means, 40 is a casing, and these devices 36, 37, 38, 39, 40 constitute an entrance block.

41 is a casing having a brick guide 42 having a U-shaped cross section, 43 is a brick feed screw, and these devices 41, 42, 43 constitute an intermediate block. 44 is an intermediate block feed screw support,
When the intermediate block is transported independently, the support portion 45 of the feed screw support 44 that can move in and out can be projected to support the brick feed screw 43. (Refer to FIG. 14) Reference numeral 46 is a casing having a brick guide 47 having a U-shaped cross section, 48 is a brick feed screw, and 49 is a rectangular tube-shaped brick dispensing device that can tilt in the direction of the arrow.
The output block is composed of 6, 47, 48, and 49.

Reference numerals 50 and 51 are members for connecting the upper and lower brick feed screws. The member 50 has a projecting portion 52 which can be inserted and removed, and the member 51 has a through hole 53 into which the projecting portion 52 can be inserted. Have The state in which the protruding portion 52 is projected and the state in which the protruding portion 52 is returned to the original position are respectively shown in FIG.
(b). The shape of the U-shaped cross section is as shown in FIG. 12 showing the BB cross section of FIG. 11.

A brick laying method using the following apparatus will be described with reference to FIG. First, the brick loading device 36 is tilted in the right arrow direction around the lower end so that the loading surface 36a is aligned with the conveyor 5 surface, and the bricks 35 conveyed on the conveyor 5 are loaded. The insertion device 36 is tilted again in the direction of the left arrow about the lower end to be upright.

The brick feed screws 37, 43, 48 are driven via the transmission means 39 by driving the feed screw drive motor 38.
Rotate together. Then, the brick 35 is gradually pushed up in the direction directly above with the rotation of the brick feed screw, and if the brick feed screw advances by one pitch, it reaches the block immediately above. Thus, the brick feed screw advances by 3 pitches and is transferred to the brick dispensing device 49.

The brick discharging device 49 can be tilted in the direction of the right arrow to discharge the bricks and load the bricks at a predetermined position in the converter.

Thereafter, the brick taken in the brick taking-in device 36 is added to the intermediate block by the same method as described above, and the whole of the blocks on the input side, the intermediate side, and the output side are moved up and down, so that the converter Bricks can be stacked at any position in the inner height direction.

[0040]

Since the present invention is configured as described above, it has the following effects. Since unmanned brick laying can be done, there is no safety problem, and bricks can be efficiently laid by an automatically controlled device. Brick can be stacked at an arbitrary position in the height direction by appropriately changing the number of inserted intermediate blocks or by moving the entire block up and down by a lifting device. No additional equipment for brickwork on the furnace,
Since the bricks are carried in from the bottom of the furnace, it is possible to efficiently arrange essential auxiliary equipment such as an exhaust gas hood on the furnace, and it is possible to make the entire equipment structure compact.
