Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block sheet manufacturing method and apparatus for manufacturing a block sheet to be laid when constructing a slope or a promenade.

[0002]

2. Description of the Related Art Conventionally, laying of a block sheet in which blocks are arranged side by side and adhered has been widely performed for bank protection, slope protection and the like. As an example of such a block sheet, in Japanese Utility Model Publication No. 51-9135, a large number of blocks are adhered to a long, water-permeable and flexible sheet with an adhesive. "Material" is proposed).

[0003]

Such a block sheet shortens the construction period and reduces the labor of the operator.
Moreover, it has the effect of making the finish constant at a high level, which is very useful. However, the work of adhering a large number of blocks to a long sheet causes a new work load, and has a problem of diminishing the advantage of improving work efficiency at a construction site. Therefore, in order to enable mass production of block sheets, it was decided to study a method for efficiently attaching the blocks to the sheets and an apparatus for realizing the method.

[0004]

What has been developed as a result is that a long sheet 51 developed in a lane 73 is provided with an adhesive application section 3 for applying an adhesive to the sheet and the sheet applied with the adhesive. The block feeding unit 4 for feeding and arranging the blocks 6 is sequentially or automatically run along the sheet 51 to produce the block sheet 5, and thereafter, on the long sheet 51 developed on the upper surface of the produced block sheet 5. A block sheet manufacturing method in which a plurality of block sheets 5 are stacked by repeatedly manufacturing the block sheet 5 while automatically or semi-automatically moving the adhesive coating section 3 and the block supply section 4 along the sheet 51 in order. Is.

The lane of the present invention means a plane on which a completed block sheet is placed. The expansion of the sheet may be performed in advance before the movement of the adhesive application section, or for example, a sheet expansion device is provided in front of the advancing direction of the adhesive application section to move the adhesive application section while expanding the sheet. You may do it. The blocks may be supplied and arranged one by one, or side by side or vertically, and a plurality of blocks may be collected at once.

In the block manufacturing apparatus according to this manufacturing method, a long sheet 51 developed on the lane 73 between the adjacent vertical rails 71, 71 or a long sheet developed on the upper surface of the block sheet 5 to which the block 6 is attached is installed. 51 comprises an adhesive application section 3 capable of applying an adhesive from above, and a block supply section 4 capable of supplying and arranging blocks from above to the sheet coated with the adhesive. Some of the parts can individually or integrally run along a vertical rail 71 or can travel along a pitch, or can traverse along a horizontal rail 72 orthogonal to the vertical rail and can move up and down. In the present specification, traveling means movement along a continuous vertical rail, pitch traveling means movement along an intermittent vertical rail, and traverse means movement along a continuous horizontal rail. The pitch interval of pitch travel is preferably based on the length of the block in the traveling direction of the manufacturing apparatus.

The adhesive applying section and the block supplying section are
The traveling directions may be the same, and they may be arranged in the order described above. Therefore, the adhesive application unit 3 and the block supply unit 4 are supported so as to be vertically movable on the frame 2 which can travel along the vertical rails 71 or can travel along the pitch or traverse along the horizontal rails 72 orthogonal to the vertical rails. The block sheet manufacturing apparatus mounted on the workbench 1 may be used. In this case, it is advisable to provide an adhesive tank on the workbench or stock a large number of blocks.

[0008]

In the block sheet manufacturing method of the present invention, while the manufacturing apparatus moves on the long sheet 51 developed in the lane 73, the block 6 is placed on the sheet 51 automatically or semi-automatically by the operation of the operator. The long block sheet 5 is manufactured by supplying, arranging, and adhering to each other, and by repeating this, the manufactured block sheets 5 are sequentially stacked.

The adhesive application section 3 applies an adhesive to the upper surface of the sheet 51 while traveling along the vertical rails 71 or traveling along the pitch. The block supply unit 4 supplies the block to the upper surface of the sheet 51 to which the adhesive has already been applied, while traveling or pitching along the vertical rails 71 from the rear of the application unit 3,
Arrange. The pitch travel is performed so that the adhesive application interval and the block array interval in the longitudinal direction of the sheet 51 can be made equal.

Further, the adhesive application section 3 and the block supply section 4 can be continuously moved on the vertical rail by traveling along the vertical rail 71, and by traversing along the horizontal rail 72, the lane 73 of the lane 73 can be moved. It switches. Further, by vertically moving individually or integrally, the height intervals of the respective parts with respect to the upper surface of the sheet 51, which is gradually increased by stacking the block sheets 5, can be always kept constant.

The frame 2 travels along the vertical rails 71 to move the workbench 1 having the adhesive application section 3 and the block supply section 4 on the sheet 51, and apply the adhesive to the upper surface of the sheet 51. Then, the blocks 6 are supplied and arranged on the coated surface. Further, the framework 2 traverses along the horizontal rail 72 to switch the lanes of the workbench 1.

Since the workbench 1 is moved up and down while being supported by the framework 2, the height intervals of the respective parts relative to the upper surface of the sheet 51, which gradually increases as the block sheets 5 are stacked, can be kept constant. In addition, the workbench 1 also has a function of allowing the manufacturing apparatus to work independently from the outside, such as installing a tank for supplying the adhesive to the adhesive application section or stocking a large number of blocks. have.

11 shows a side view of the clip. Block clip 42
Is provided with chucks 44 that are opened and closed by an air cylinder 43, and these chucks 44 are attached to the lower end of a telescopic arm 46 that can be extended and retracted by feeding and rewinding a chain 45. This telescopic arm 46 hangs on a front and rear bar 47 of H steel directed in the front and rear direction of the frame 2 via a roller 48, and further hangs the front and rear bar 47 on a horizontal H steel of the upper side 23 of the frame via a roller 49. It has a structure. With such a structure, the chuck 44 that holds the block 6 can be moved back and forth and left and right, and the blocks 6 can be aligned when they are supplied and arranged.

A process of manufacturing a block sheet using the manufacturing apparatus having the above structure will be described with reference to FIGS. 1 and 2. First, the manufacturing device 8 has a vertical rail 71.
The worker traverses on the horizontal rail 72 (see FIG. 3) at the starting end, and the worker moves to the vertical rails 71, 71 that sandwich the lane 73 where the seat 51 is developed. As a preparation, the pallet 61 on which the blocks 6 are loaded is placed on the conveyor 61 of the workbench 1, the adhesive tank 32 is filled with the adhesive, and the worker rides on the workbench 1 and is the block supply unit 4. Block clip 42 and adhesive application section 3
The manufacturing apparatus 8 is gradually advanced while operating.
The operation by the operator is limited to the alignment of the operating parts and the monitoring of malfunctions, and the work as a whole proceeds semi-automatically. Therefore, it is also possible to use a position measuring sensor for full automation.

As shown in FIG. 1, the manufacturing apparatus 8 is moved by the rail clamp mechanism 25 at a pitch corresponding to the length of the block 6 in the moving direction of the manufacturing apparatus 8. In the present embodiment, since the blocks 6 are supplied and arranged side by side in units of six, the manufacturing apparatus 8 is run in units of one pitch. The adhesive is applied to the sheet 51 at each pitch.

In the nozzle 31 of this embodiment, the adhesive can be dropped onto the sheet 51 at two places at a time, and the application of six places in a row at each pitch can be performed with three accesses. If the adhesive can be applied to a plurality of places at the same time in the same row, the work efficiency can be improved.
The manufacturing apparatus 8 temporarily stops when it has advanced by one block, and moves to the supply and arrangement of the block 6 behind the sheet on which the adhesive has already been dropped.

The manufacturing device 8 advances, and the block clip 42
The sheet 51 on which the adhesive is applied by the adhesive applying section 3 below
Once the parts are in place, the worker has the pallet 61 on the conveyor 41.
After holding the blocks 6 by the block clip 42 in units of 6 units, aligning the front, rear, left, and right, horizontally rotate the blocks 6 to align them side by side, and supply and arrange the blocks 6 on the seat 51 below the workbench 1. . In this embodiment, block 6
In order to emphasize the orthogonality of the array of, the block clip 42
Six blocks 6 to be supplied at one time are arranged side by side by repeating horizontal rotation of 90 degrees. However, if the positioning and the like can be accurately performed using a sensor or the like, the block clip can be freely horizontally rotated at an arbitrary angle.

After the blocks are arranged in units of six by the block clip 42, the manufacturing apparatus 8 is advanced by one pitch again. After that, while the adhesive is applied to the sheet 51 for each pitch, the manufacturing apparatus 8 performs the above-mentioned procedure on the sheet.
The long block sheet 5 to which the block 6 is attached is manufactured by repeating the process until reaching the end of the vertical rail 71 or 51.

Manufacturing apparatus 8 which has reached the end of the vertical rail 71
This time, the traveling wheels 26 are used to continuously move without applying adhesive or supplying blocks, and return to the starting end of the vertical rail 71. Next, in order to produce a new block sheet 5 by overlapping the produced block sheet 5, the workbench 1 is lifted by the height of the block 6, and at the same time, a buffer is placed on the upper surface of the already produced block sheet 5. After a veneer board or the like is laid for use, a new sheet 51 is developed. Next, the above manufacturing process is performed on this new sheet 51, and by repeating this, as shown in FIG. 2, the block sheets 5 are sequentially stacked while manufacturing the block sheets 5. You can

The block sheets 5 thus manufactured in the stacked state are transported by a truck in the stacked state, individually laid down at the construction site, and laid for protection of the bank and slopes. Further, if temporary storage is required after manufacturing, the stacked state can be stored in the warehouse as it is, so that it is possible to save the trouble of loading it on the truck again later.

In this embodiment, the seat 51 in the lane 73
And the attachment of the block 6 to the seat 51 are separate from each other, and the operator depends on the development of the seat 51. However, as shown in the example of FIG. 12, for example, by arranging the roll 52 wound with the sheet in front of the traveling direction of the manufacturing apparatus 8 of the workbench 1, it is automatically adjusted according to the progress of the manufacturing apparatus 8. The seat 51 may be unfolded in the above.

In this embodiment, the application of the adhesive, the supply of the blocks, and the arrangement are simultaneously performed for each pitch. That is,
Although the application of the adhesive agent is preceded by the positional relationship of each device, when the supply and arrangement of the blocks are started, the application of the adhesive agent and the supply and arrangement of the blocks side by side are simultaneously performed. . By doing so, the time from the application of the adhesive to the supply of the block and the attachment to the sheet becomes constant, and it is possible to always manufacture a block sheet having a constant quality.

In addition, the block applying sheet may be manufactured by separating the adhesive applying section and the block supplying section and individually operating them as independent manufacturing apparatuses. Further, instead of running the manufacturing apparatus along a fixed vertical rail or the like as in this embodiment, the manufacturing apparatus can be performed by detecting the developed sheet edge portion using an optical sensor or the like. If the block can be freely moved, for example, a block can be attached to a bent sheet to manufacture a curved block sheet.

[0036]

By the block sheet manufacturing method and the block sheet manufacturing apparatus of the present invention, it becomes possible to produce a large number of block sheets more efficiently and with less manpower than ever before. Moreover, if the unfolding of the sheet is performed from the workbench of the manufacturing apparatus and the unfolding sheet is detected by the sensor so that the manufacturing apparatus can automatically correct the position and proceed, the block sheet is almost fully automated. Since it becomes possible to manufacture the same, it is possible to further improve the efficiency, and these advantages have the effect of reducing the cost of the block sheet.

On the other hand, since the manufactured block sheets can be successively stacked, the labor of the operator in transporting and storing the manufactured block sheets can be reduced, which is convenient when the block sheets are handled collectively.
