DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight cellular concrete cutting apparatus, and more particularly, to shortening a pulling-back time of a mobile trolley after a cutting operation, thereby improving productivity of lightweight cellular concrete. The present invention relates to a lightweight aerated concrete cutting device that can reduce costs.

[0002]

2. Description of the Related Art As a kind of wall plate of a building, a plate material made of lightweight cellular concrete having a light weight and good fire resistance is known. This plate material is manufactured by cutting a semi-dry and thick block-like lightweight cellular concrete into a predetermined width by a lightweight cellular concrete cutting device having a piano wire. 2. Description of the Related Art As a conventional lightweight cellular concrete cutting device, there is known, for example, the one disclosed in the specification of FIG.

In this apparatus, a split support plate for downwardly supporting a semi-dry, horizontally elongated lightweight cellular concrete is fixed to a tip of a rod of a large number of air cylinders arranged in two rows in a machine length direction, and a guide rail. A gate-shaped movable trolley movable in the machine length direction is disposed along the upper side, and a cutting frame having a lower frame movable between the lowered divided support plate and the lightweight cellular concrete is suspended on the movable trolley. It is attached in the lower state. A large number of piano wires for cutting lightweight cellular concrete are attached to the cutting frame at predetermined intervals.

In this conventional lightweight cellular concrete cutting device, when the lower frame of the cutting frame approaches the air cylinder with the movement of the movable bogie in the machine length direction, the switching valve is automatically switched by a control device. The divided support plate is returned to the original position by sequentially lowering the rod so as to avoid a collision and immediately switching the switching valve to protrude the rod after passing. This operation is to cut the lightweight cellular concrete to a predetermined width by the cutting material while performing the operation sequentially and continuously for each air cylinder.

[0005]

By the way, after cutting the lightweight cellular concrete, the movable trolley is pulled back to the original position along the guide rail. However, even after the lightweight cellular concrete is carried out, the divided support plate is in the raised position. Therefore, if it is pulled back as it is, the lower frame of the cutting frame collides with the divided support plate with the movement of the movable trolley, and both members are damaged. To solve this problem, as shown in FIG. 5, for example, as shown in FIG.
It is conceivable that after moving all the 03 down, the mobile carriage (not shown) is pulled back. In the drawings, reference numeral 104 denotes lightweight cellular concrete, and reference numeral 105 denotes an electromagnetic valve.

However, in this method, since the air in the air cylinder 101 is extracted using the bypass circuit 102, it is faster than switching the solenoid valve 105 one by one to extract air, but it is equivalent to extracting internal air. There is a problem that it takes time and the productivity of the lightweight cellular concrete is reduced, and a problem that a complicated bypass pipe is required and the equipment cost is increased.

[0007] The present invention has been made in view of such circumstances, and can reduce the retraction time of the movable cart after the cutting operation,
This can improve the productivity of lightweight cellular concrete,
It is another object of the present invention to provide a lightweight cellular concrete cutting device capable of reducing equipment costs.

[0008]

According to the present invention, there is provided a semiconductor device comprising:
The light-weight cellular concrete cutting device according to the present invention is provided with a number of air cylinders having rods mounted side by side in the machine length direction and having a divided support plate of lightweight cellular concrete in a semi-dry block state, and a machine head along a guide rail. A movable carriage that can move in the direction, and a large number of the lightweight cellular concrete cut materials attached to the movable carriage are attached at predetermined intervals, and the gap between the lowered divided support plate and the lightweight cellular concrete is lowered. It is configured to include a cutting frame having a lower frame that can pass therethrough, and lifting means for the cutting frame provided on the movable carriage.

[0009]

In the lightweight cellular concrete cutting apparatus according to the first aspect, after the lightweight cellular concrete is cut, the lightweight cellular concrete is carried out from the divided support plate, and then, while the rod of the air cylinder is projected, the lifting means is used.
The cutting frame is pulled up until the lower frame is placed on the split support plate, and then the moving cart is pulled back at high speed along the guide rail, so that the moving cart withdrawal time after the cutting operation can be shortened, thereby operating the device. The rate increases, and the productivity of lightweight cellular concrete can be improved.

As shown in FIG. 1 and FIG.
A large number of air cylinders 15 arranged in two rows in the machine short direction are arranged in the machine length direction with the rod 16 facing upward. A split support plate 17 for splitting and supporting the lightweight cellular concrete 11 is horizontally laid at the tip of the paired rods 16.

[0013] As shown in FIGS.
Has a movable carriage 24 that moves on the guide rail 13. A portal frame 25 is mounted on the movable trolley 24. Inside the portal frame 25, a number of piano wires 26 as an example of a cutting material extending in the X direction are stretched at a constant pitch in the Y direction. A piano wire cassette frame 27, which is an example of the cut frame body, is detachably attached.
The piano wire cassette frame 27 allows the rods of the air cylinders 28 arranged in pairs at the upper and lower portions of the gate-shaped frame 25 to be taken in and out, and the tapered stopper 29 fixed to the tip of the rod is moved to the four corners of the piano wire cassette frame 27. By fitting into and removing from the tapered hole 30 formed at any one corner, the piano wire cassette frame 27 can be firmly hooked to the gate-shaped frame 25 or can be detached so that it can be replaced with another cassette frame. ing. The piano wire cassette frame 27
In another corner, a taper groove (not shown) for vertical positioning is formed.

When the movable carriage 24 approaches the predetermined air cylinder 15, the corresponding rod 16 is retracted to form a gap between the lower surface of the lightweight cellular concrete 11 and the upper surface of the divided support plate 17, and this gap is formed. Is formed, the lower frame 27a of the piano wire cassette frame 27 passes. After the passage, the rod 16 of the air cylinder 15 is protruded, and the lightweight cellular concrete 11 is supported by the divided support plate 17 again.

A feature of the present invention is that a pull-up means 31 capable of pulling up the piano wire cassette frame 27 is provided. The lifting means 31 has a hydraulic cylinder 32 mounted on a central portion of an upper frame 25 a of a gate-shaped frame 25, and an elevating frame 34 fixed to a tip of a rod 33 protruding downward. On the other hand, connecting pieces 27b protrude from upper corners on both sides of the piano wire cassette frame 27, respectively, and these connecting pieces 27b are connected to both sides of the lifting frame 34 via pins.

Guide rings 35 are mounted on both sides of the upper frame 25a, and guide rods 36 mounted on both sides of the elevating frame 34 slide as the rod 33 of the hydraulic cylinder 32 is inserted and removed. I can do it. The lifting height of the lifting frame 34 is determined by the lower surface of the lower frame 27a of the piano wire cassette frame 27.
This is the height arranged on the divided support plate 17. In the figure, reference numeral 42 denotes wheels, reference numerals 43 and 44 denote mounting members,
Reference numerals 45 and 46 denote back support members of the piano wire cassette frame 27, and 47 denotes a piano wire holding member.

Next, the operation of the lightweight cellular concrete cutting apparatus 10 according to one embodiment of the present invention will be described. As shown in FIG. 1, the movable cart 24 is moved along the guide rail 13 by X.
When the piano wire cassette frame 27 approaches each air cylinder 15, the rod 16 of the air cylinder 15 is retracted, and the divided support plate 17 is lowered.

During the descent, the lower frame 27a of the piano wire cassette frame 27 that moves together with the movable carriage 24 passes through the gap between the lightweight cellular concrete 11 and the divided support plate 17,
The lightweight cellular concrete 11 is cut into a predetermined width through the piano wire 26. Thereafter, the rod 16 of the air cylinder 15 is protruded, and the upper surface of the divided support plate 17 is brought into contact with the lower surface of the lightweight cellular concrete 11. This operation is sequentially performed for all the air cylinders 1 with the movement of the movable carriage 24.
5, the cutting of the lightweight cellular concrete 11 by the piano wire 26 is completed.

After cutting the lightweight cellular concrete 11, the lightweight cellular concrete 11 is carried out from the divided support plate 17, and the movable cart 24 is moved along the guide rail 13 in order to perform the next cutting operation of the lightweight cellular concrete 11. Is pulled back to the original cutting start position. That is, as shown in FIG. 4, the fixed state of the piano wire cassette frame 27 is released by retracting the rod of the air cylinder 28, and then the hydraulic cylinder of the lifting means 31 When the rod 33 of 32 is retracted, the elevating frame 34 rises, and the piano wire cassette frame 27 moves its lower frame 27a to the divided support plate 1 in the raised position.
It is pulled up to a height position where it does not come into contact with 7. In FIG. 4, a line a is an upper surface line of the divided support plate 17. Then, the movable cart 24 is pulled back along the guide rail 13 at high speed.

As described above, after the lightweight cellular concrete 11 is cut, the air in the air cylinder 15 is evacuated, and the multiple air cylinders 15 are cut without lowering the divided support plates 17.
Since the piano wire cassette frame 27 can be moved at a high speed, the retraction time of the movable cart 24 after the cutting operation can be shortened, thereby increasing the operation rate of the apparatus and improving the productivity of the lightweight cellular concrete 11. . Moreover, since a complicated bypass circuit as described in the section of the related art is not required for the air pressure system of the air cylinder 15,
Equipment cost can also be reduced.

For example, the means for raising the cutting frame is not limited to the structure of the embodiment, but any means capable of raising the lower frame of the cutting frame above the concrete placement position of the divided support plate. Anything may be used.

Furthermore, in the embodiment, the moving carriage is shown as moving along guide rails arranged on both sides of the apparatus. However, the present invention is not limited to this. It may be of a suspended type that moves along a guide rail disposed above a lightweight cellular concrete placing device. In the embodiment, the piano wire is shown as the cutting material of the lightweight cellular concrete. However, the invention is not limited to this, and any material may be used as long as it can cut the lightweight cellular concrete. Also, the method of attaching the cutting material to the cutting frame body is not vertical stretching as in the embodiment,
It may be horizontal.
