Abstract

PURPOSE:To enhance the operational efficiency and automate operations by grasping each of the units of objects to be transported, which are stacked neatly prior to carrying-in to a yard, and placing them in the yard in good alignment. CONSTITUTION:Over space-sensing blocks B1 placed close to one another and in a transverse row of a length equal to the yard stack width l, another row of blocks with an orientation 180 deg. changed from the above-mentioned blocks are placed to provide plural-stage stacked blocks B2 in a transverse row. The plural- stacked blocks B2 in a transverse row are put close to one another in the direction fore and aft to provide a unit group A for transportation, and these unit groups A are carried to the yard one after another and stacked there in a width of a single transverse row. According to this arrangement, the operational efficiency can be enhanced and the operations fully automated.

Description

[Detailed Description of the Invention] This invention relates to a method and equipment for stacking molded and cured products in a yard (yard) at a mass production factory for civil engineering blocks, which improves efficiency, makes effective use of yard area, and achieves full automation. With the goal.

The production of machi blocks has improved significantly with the adoption of an instant demolding method and the development of molding equipment. However, the subsequent processing of the formed blocks has not been very advanced. As always, manpower and forklift trucks that can replace manpower are essential. In the case of the immediate demolding method, the blocks that come out of the curing area are placed on a pallet, and since the blocks are solidified, they are peeled off by hitting them with a hammer, and several pieces are taken to the yard using a forklift truck. At present, they are either transported to a warehouse and stacked side by side, or unloaded and stacked manually.

The block hoisting device of a forklift truck is
Hold the ``stacks'' or ``joint ends'' individually or in several rows using long clamping materials.

I'm using this in various ways. Yard stacking is usually done as shown in Figure 1.2. In the case of Figure 1, when using the machi block, the exposed surface is likely to be stacked and scratched.

In the case of Figure 2, it is easy to get messy. And it takes a lot of nerves, time, and effort to stack them in an orderly manner in the yard.

The basic concept of this invention is to transport blocks one by one using a forklift vehicle, as in the past, and to build them up in a yard.
Instead of arranging them in a row, large transportation units are mechanically arranged to the required width and stacked on top of each other before entering the yard, and then they are gently grabbed and lined up in the yard. Next, the configuration and implementation aspects of the present invention will be explained with reference to the drawings.

Fig. 3 is a plan view of the vicinity of yard Y of a factory for mass production of instant demolding intelligent blocks employing this invention, Fig. 4 is a plan view showing the movement of block B before it is moved to the yard, and Fig. 5 is a plan view of this embodiment. An example of the intermittent block B is shown.

The conveyor l at the right end of Fig. 3 carries the blocks B from the curing field in a single line as shown in Fig. 4, and sends them to the block transportation unit group forming position t near the yard Y. The transportation unit group A made at the group creation position λ is placed on the traverser 3 on the yard Y side. Torano (-sa) 3 runs on the railda and stops at one end of the four storage areas S lined up in yard Y in the example shown in Figure 3.Then, lane 6 in which it runs 3, and pick up the transportation unit 1f-Ak and stack it in sequence at the storage area 5. There is also a traverser JtL on the loading side of yard Y.
], the transport vehicle 7 gets on board and loads it to the crane B.

The yard stacking method of this invention is summarized as follows. That is, the same row of blocks B1, which are arranged in a horizontal row with a length equal to the yard width J, are placed in a row in the same direction and closely arranged, and the blocks are stacked in multiple stages B2, with the orientation changed by a total of 180 degrees. a step of forming the plurality of stacked blocks B2 arranged horizontally in one row, a step of making one transportation unit group Aft by closely adjoining the plurality of stacked blocks B2 arranged horizontally one after another in the front and back direction; and a step of forming one transportation unit group Aft. Is it to have a process of transporting them one after another to Yard Y, stacking them in the width of the above-mentioned horizontal line, and moving them horizontally? This is a characteristic feature.

As shown in Fig. 6, the block Bi in the standing position has a cylinder g for horizontally laying it down.
If the pallet P is restrained with a hook or the like so that it does not move together when pushing down the pallet P, it can be easily peeled off (patent pending).

The entire yard stacking device of this invention can be summarized as follows. In other words, pick up the ``joint ends J'' that are lined up in a horizontal row in a row in the same direction, and change the orientation to 1.
A single row of blocks B, v that can be moved up by 80 degrees and moved by // and this device ii.
Movable loading platform with rt prevention material 7.2 for making one transportation unit group A by stacking multiple stacks with f'' direction alternately changed by 180 degrees Bzk one after another closely adjacent in the vertical direction / 3 Then, grab the above group At from the front, back, left and right, and lift it up to Yard Y.
This is Kanchi Block's yard stacking device, which is equipped with a movable large-scale upstream device/lI that can be transported to.

As shown in FIG. 3, at the transportation unit group creation position 1, the - row block upstream device/l and the movable large sized upstream device/4' work in their respective areas, and the movable loading dock 13 is located below them. There is. At the right end of Figure 4, the conveyor L holds the blocks until the stacking width J in the yard is n, and when the detection device detects that five blocks are lined up in this case, they are turned sideways as shown in Figure 6. Peel off the pallet pl. Then, all the blocks lined up in a row in this sideways position - the block upstream device/
Move to movable loading dock/J by l.

- An embodiment of the row block run-up device// is shown in Figure 8.9. Both ends of the five "joint ends" of the arranged blocks B are held between the rubber surface clamps 1S, and in order to prevent the rows of "joint ends" from bending, each block boundary part is secured to the "surface" side fixing plate 1.
6. It is designed to be held between the "reserve" side rotating push claws 17. Push claws/7 blocks enter into the gap between the "reserves" of adjacent blocks and indirectly control the bending of the "joint" row. In addition, the entire clamping mechanism is inclined as shown in Fig. 9 according to the inclination of the mating end J10, and in order to pick up the block row B1 and turn it 180 degrees, the rack 1g1 pinion/
9. It is different from conventional cushioning of this type in that it is equipped with a fluid pressure cylinder J. The above-mentioned gripping and turning mechanism hangs down from a truck 2 on the frame, and the truck 22 can be moved a fixed distance by means of a hydraulic cylinder 2).

As shown in FIG. 7, the movable & exhibition area 13 is a slat conveyor in this example. It moves intermittently in the direction of the arrow.
In Fig. 4, the one-row block Bq of horizontally falling tabakashi is placed immediately behind the collapse prevention material/2 of the loading area 13, in this case,
Turn it around and place it. Then, place the one-row block B+ (which does not change its direction) on top of it without changing its orientation so that it does not slip and fall, then move the conveyor in the loading area 13 by one pitch, and place the two-layer block B2 that you just made Repeat the process of creating a two-tier stacked block Bzt- immediately after it and following the same procedure.The collapse prevention material is required only at the beginning. When the person is ready, the large tank raising device/lI that was waiting on the traverser 3 side grabs the group A and moves it onto the traverser 3. An example of this large tank lifting device/lI is
As shown in the figure. In this example, 60 blocks B stacked in two levels are picked up at once, and the horizontal movement mechanism is omitted, and only the clamp portion is shown. The base frame sword is rectangular when viewed from above, with a clamp 2 with a rubber clamp 2 for holding the outermost joint end J10 of each block on the long side, and a lower block B on one of the short sides. On the other hand, there is a holding plate core that corresponds to the "face" of the upper block B, and a stop plate core that corresponds to the upper half of the "face" of the upper block B.

The width of the storage area S in the yard Y is such that the transportation unit groups Ai are stacked in two rows on the width, and the gap between the two rows is not very narrow, so the "joining end" of the large tank lifting device/I Even if the clamp J on both sides is a sufficiently strong rotation type, it will not hit the block placed earlier. The restraining plate 26 and the abutment plate 27 that hold down the "face" of the block are simple devices without rubber because they are auxiliary means to prevent the jib block group members from being arranged randomly due to the pressure force of the clamp J. In particular, in order to stack Group A one after another in the storage area 5 of the yard, the near side of the board is designed to be narrow and short so that it can fit into the gap between the "reserves" of the blocks of Group A placed earlier.

The large tank raising device/lI that is transferred from the loading area lJ at the group Ai group production position to the traverser 3 is moved and raised/lowered on a traveling device (not shown). The same-shaped lifting mechanism /lIα attached to the inter-type crane B can also be moved horizontally, so that the cargo can be stacked in two rows in group Ai. -yFfAv of each ramming yard S
In c, there is a retaining wall Sα for preventing collapse.

Although the present invention has been described above with reference to one embodiment, it is possible for the engineer in charge to make various changes and applications according to the implementation conditions without changing the gist thereof, based on the known technology. In the above embodiment, the blocks B1 and B1 are stacked horizontally in two rows and are arranged vertically, but for example, the blocks Bzk, rt, stacked in three or four rows may be arranged side by side to form group A.

However, in that case, it is necessary to lengthen the backing plate 27 shown in Figure 10.12 along the slanted "face" of the block so that the second and third tier blocks B will float and collapse. .

This invention succeeded for the first time in streamlining the method and equipment for stacking machi blocks in yards, which are cumbersome to transport and stack in yards.

Forklift trucks, which have traditionally been the mainstay of yard loading,
In fact, transporting the blocks and organizing them was a labor-intensive process with no results.

This invention did not mechanize work that used to be done with forklift trucks. By laying the machi blocks in a row horizontally and stacking them in different directions, you can create multi-level blocks B2 in horizontal rows.
We developed a masonry method suitable for mechanization in which materials are lined up vertically to form transportation units. Then, we solved difficult problems such as a device to pick up and operate blocks in rows, a mechanism to arrange the picked up blocks to form a group without breaking them, and a device to shake the group to prevent it from collapsing. By using this method, we created a group of transportation units that were pre-assembled in the yard across the stacking width using machines with high precision and high efficiency, making it possible to stack items in an orderly manner by simply placing them one after another in the yard. This ability to accurately stack blocks in multiple rows at the yard makes it easy to load the required number of blocks onto trucks and ship them under computer control, similar to modern warehouses.
