Abstract

PURPOSE:To improve the efficiency of the work to pile up blocks by adopting a construction to hold and move blocks directed in a fixed direction between several clamps vertically reversing for shaping the first stage, pile them up reversely for the second stage, and repeat this process afterwards. CONSTITUTION:Clamps 8 and 8' are brought down for blocks 1 on parallel conveyors 4, and blocks are held between clamp plates 10'. Then as an elevating frame 7 is brought up, clamps 8 and 8' are moved to the central part of the elevating frame 7 by a collecting cylinder 17 and a chain device 17'. Blocks 1 are lined up on an unillustrated piling-up conveyor. Subsequently, blocks 1 for the second stage are changed in their direction at 180 deg. by an unillustrated turntable, and similarly clamped by clamps 8 and 8'. They are then vertically reversed, and moved on to the piling-up conveyor for shaping the second stage. This construction permits to obtain a high efficiency for the work to pile up blocks.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete block masonry method and apparatus.

Concrete blocks have a basic type and accessories such as root stones, top stones, and side stones. As shown in Figures 1a to 1C, most of the basic model has a rectangular cross-section of the mirror surface A and the buttock part B, and most of the accessories have mirror surfaces as shown in Figures 2a to 2c. The cross sections of A and the buttock portion B are both pentagonal.

When these blocks are piled up, they are usually piled up in the open with the mirror surface A facing down. However, when piled up in the open like this, the mirror surface area A, which should be the surface when concrete is piled up, is in a wet state, so the surface often becomes dirty, and the normal open piled condition is unstable and may not be piled high. Therefore, a large area was required for accumulation. Particularly in the case of ornaments, stacking them on top of each other with the mirror surface facing down is unstable and there is a high risk of them falling over, so a method is adopted in which they are stacked by hand by alternately tipping them over. Even if attempts were made to mechanize this work, there was a problem in that the process was complex, the processing capacity was low, and several devices were required to integrate the blocks into each block forming line.

This invention is a concrete block masonry method that automates the masonry of not only basic type blocks but also service blocks, which can be performed with high efficiency, and which can be connected to the high-efficiency molding lines currently in use. and equipment.

The method of the present invention includes: a) arranging a predetermined number of concrete stacked blocks in a row under the gate form so that their mirror surfaces are in the same direction; b) provided on a trolley placed on the gate form; Using multiple clamps that are movable up and down and capable of turning the clamped object upside down, each clamp holds one of the above blocks, C9 raises the above clamps, and moves the cart to the masonry position1.
(c) Lower the clamp at that position, release the clamped block, and arrange the first stage of blocks. (d) Place a predetermined number of concrete stacked blocks under the gate form so that the mirror surface is about the same as aI above. Arrange the blocks in a line in the opposite direction to the above. e. Sandwich the blocks in the same way as in the above step, and then turn the blocks upside down. f. Move the cart to the masonry position as in the above step C, and Releasing the blocks on top of the first row and arranging the second stage; 9. The steps a to C above are considered as one cycle, and by repeating this, the concrete blocks are laid in a predetermined number of stages. This is the way to do it.

The configuration of the device for carrying out the above method is as follows: a transfer conveyor 2 that continuously transfers concrete stacked blocks 1 at equal intervals; a turntable device 3 connected to this to change the direction of the blocks; 1 in parallel conveyors 4, a gate frame 5 provided on the top of the parallel conveyor 4, a movable trolley 6 placed on the gate frame, the lower end of which can clamp, invert, and release the blocks, and This is a concrete block masonry device which is equipped with a clamp 8.8- which can move in parallel with the parallel conveyor 4, and has an elevating frame 7 supported by the moving cart 6 so as to be able to be raised and lowered.

To explain this invention in detail with reference to the drawings, as shown in FIG. A parallel conveyor 4 and a masonry conveyor 9 connected to the transfer conveyor 2 are provided.

As shown in FIGS. 4a and 4b, the elevating frame 7 is
At least one pair of clamps 8.8' that can clamp and release blocks; wheels 16, cylinder 17, and chain device 17-1 for moving the clamps in the longitudinal direction of the lifting frame l;
Chain wheel 17# and clamp 8.8- hold the block,
6 - A cylinder 13 that operates this so that it can be released, a clamp moving guide 14, a clamp plate 10 and 10 in the part where the clamp contacts the block, a rotating device 11 for rotating the clamp plate, and a rotating chain 12. The entire elevating frame can be moved in the vertical direction by guides 19, 19' and elevating cylinders 18, 18' provided on the moving carriage 6.

Since the movable cart 6 can be moved on the gate frame 5 in the width direction of the elevating frame by the movable wheels 20, the blocks held between the clamp plates can be moved on the parallel conveyor 4 and the masonry conveyor 9. It can be moved forward, backward, left and right.

To explain the process of masonry of blocks using the apparatus of this invention, concrete blocks 1 which have gone through processes such as molding, curing, drying, boarding such as a face plate, and laying on their sides are placed on a transfer conveyor 2 at approximately equal intervals. The blocks are placed and transferred, and the blocks are passed through without changing their direction by the turntable device 3 installed in series, and a predetermined number (for example, 6 blocks) are arranged side by side on the parallel conveyor 4.

The movable cart 6 attached to the gate frame 5 is moved onto the parallel conveyor 4 as shown in Fig. 3, and the lifting cylinders 18 and 18- shown in Figs. 7 and open the clamp 8.8' until the block on the parallel conveyor 4 is placed between the clamp plates 10.10- attached to the tip of the clamp 8.8-. 5a by actuating the cylinder 13 that moves the clamp 8.8'.
As shown in FIG.
While lifting the elevating frame 7 by clamping it with the clamp plates 10 and 10-, as shown in FIG.
, operate the chain device 17-1 and the chain wheel 17'' to move each clamp 8.8' to the center of the lifting frame 7.
is moved onto the masonry conveyor 9 where the block is to be laid, the lifting frame is lowered, and when the block touches the conveyor 9, the clamp 8.
8- is opened, the blocks of the first stage are placed side by side on the masonry conveyor 9 as shown in FIG.

Next, as shown in FIG. 8, the direction of the blocks 1 being transferred by the transfer conveyor 2 is changed by 180° using the turntable device 3, and as shown in FIG. ) Arrange. As explained earlier, after clamping this with the clamps 8.8' of the lifting frame 7, the lifting frame is raised, and as shown in FIGS. 10a and 101), the rotating device 11 provided on the clamp and rotate the clamp plate 10.10-180° via the rotating chain.
After rotation, clamp 8.8' as shown in Figure 11.
to the center of the lifting frame 7. Move the mobile cart onto the row of six blocks lined up earlier, and lower the elevator frame so that the five reversed second-tier blocks are stacked between these six blocks, as shown in Figure 12. , clamp8.
Release 8- and 9-.

The above-described process is considered as one cycle, and after concrete blocks are laid, a field piling process is carried out.

The operation of the device of the present invention has been explained above with respect to the masonry method of accessory blocks.
The process involves transporting and arranging several blocks, and in the second step, arranging them in rows with opposite directions, and stacking the blocks so that the mirror surface A of the blocks is on the outside and the butt ends B of the blocks are in contact with each other in one cycle. As a result, blocks can be stacked on top of each other.

This invention not only automates the masonry of concrete blocks and can process them at the speed of a high-speed molding line, but is also effective in saving open pile area and preventing the danger of open piles.
Since the mirror surface of the block is exposed on the side when it is piled up in the open, it has the remarkable effect of making it easy to inspect and manage the product.
