Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a semi-hardened material cutting device, in particular, a device for cutting a semi-hardened material, in particular, a device for cutting a semi-hardened lightweight foamed concrete material in the longitudinal direction of a lightweight aerated concrete material. This invention relates to a device for cutting semi-cured lightweight cellular concrete by horizontally moving the concrete body.

[Conventional technology and problems to be solved]

The following various devices have been proposed as conventional devices of this type.

In the apparatus shown in FIGS. 3 and 4, a wire-shaped cutting member 1 is suspended from an upper fixing member 10 that runs along a rail 9, and a semi-hardened lightweight aerated concrete body 2 is attached to the lower end of the wire-shaped cutting member 1. Support 3 to be placed
A plurality of rod-shaped bodies 1 running in a plurality of grooves 11 inside.
It is fixed at 2. Incidentally, the groove 12 has an extremely thin slit in its upper part through which the wire-like cutting member 1 passes.

This device has a structure in which the cutting member is dragged at the upper end, and the lower end is connected to independent rod-shaped bodies, so it is possible to monitor the running state of each cutting member and the cutting member. The cutting resistance applied will change. As a result, the cut surface of the semi-hardened lightweight cellular concrete body lacks smoothness, especially near the lower end, or in extreme cases, breaks.

In addition, the apparatus shown in FIG. 5 is provided with a plurality of supports 3 in the length direction of the semi-cured lightweight cellular concrete body 2, and when the cutting member 1 passes, the supports 3 are lowered and cut. This is a device that allows the member 1 to pass through the lower fixed frame.

This device has a structure in which the support 3 that has been lowered during cutting is raised again to support the cut and thinned concrete body 2.

Therefore, when the cut and thinned concrete body 2 collides with the raised support 3, the semi-cured lightweight cellular concrete body 2, which is also cut,
The lower part of the is damaged.

In addition, the apparatus shown in FIGS. 6 and 7 lifts the semi-cured lightweight cellular concrete body 2 using a suction suspension device 13, and in that state, the suction suspension device 13
This device cuts a semi-cured lightweight aerated concrete body 2 with a cutting member 1 which is suspended from a lower end fixed frame to a lower end fixed frame.

This device requires a strong suction force to suspend the concrete body 2, and as a result, the concrete body 2
The close relationship between the concrete body and the suction suspension device 13 is similar to the close relationship between the concrete body and the support body shown in FIG. A cutting defect occurs at the lower end of the body 2.

The apparatus shown in FIG. 8 is an apparatus in which the concrete body 2 is held and lifted by the gripping member 14 while being pressed from the left and right sides, and in this state is cut by the cutting member 1.

In this device, the cut concrete bodies were in close contact with each other even after cutting, so it was difficult to separate them after the cutting process was completed, and if they were forcibly separated, chips also occurred.

As described above, the conventional apparatus has the disadvantage that the cut semi-cured lightweight cellular concrete bodies are easily damaged, and the cut surfaces are not smooth.

Furthermore, with the equipment shown in Figures 3 and 6, it is impossible due to the structure of the equipment to reciprocate the cutting member in the vertical direction and move it horizontally to cut the lightweight aerated concrete body along the longitudinal direction. However, in the apparatus shown in Fig. 6, even if the cutting member is moved horizontally while reciprocating in the vertical direction, the effect of such a configuration cannot be exhibited due to the above-mentioned drawbacks, and the apparatus shown in Fig. 5 In order to move the cutting member in the horizontal direction while reciprocating in the vertical direction with the device shown in FIG.
The lifting distance of the support 3 increases, and the damage to the cut concrete body increases.

In this way, due to the structural limitations of the above-mentioned conventional equipment, even if the cutting member is reciprocated in the vertical direction and moved horizontally to cut the lightweight aerated concrete body along the longitudinal direction, it is not particularly effective. I was unable to demonstrate my abilities.

An object of the present invention is to provide a cutting device that eliminates the drawbacks of conventional devices, has extremely few defects in cut lightweight cellular concrete bodies, and can provide smooth cut surfaces.

[Means to solve problems]

The present invention provides an apparatus for cutting a semi-hardened lightweight cellular concrete body by moving a wire-like cutting member horizontally in the longitudinal direction of the semi-hardened lightweight cellular concrete body relatively within the concrete body. The support base on which the wire-like cutting member is placed is divided along the running direction of the wire-like cutting member, and the wire-like cutting member is composed of a plurality of generally parallel wire-like cutting members, and the plurality of wire-like cutting members are generally parallel to each other. The upper and lower ends of each are fixed to an upper fixing frame and a lower fixing frame of the frame body, such that the upper fixing frame is located above the concrete body and the lower fixing frame is located below the support base. The wire-like cutting member has a structure in which the supporting stand is supported by the supporting member only at the outer ends of both sides in the running direction of the wire-like cutting member, and the wire-like cutting member is fixed at the top and bottom to the frame between them. It is movable in the horizontal direction, and further includes a mechanism in which the frame body, which fixes the wire-like cutting member with its upper fixing frame and lower fixing frame, reciprocates in the vertical direction within a support frame provided on the outside thereof. This is a cutting device for a semi-cured lightweight cellular concrete body characterized by having a structure in which a wire-shaped cutting member can be moved vertically while being moved horizontally.

Furthermore, if the support base has an uneven structure along its length so that there are parts that come into contact with the semi-cured lightweight cellular concrete body and parts that do not come into contact with it, the cut surface will be even better, and the Pallet receiving rods for transferring concrete bodies can be inserted into the non-contacting areas.
In addition, after the concrete body is cut, a comb-shaped receiving rod having a frame at one end is inserted from one side, and assembled with another frame on the other side to form a ladder-like pallet. It is preferable to transport the cut concrete bodies as transport pallets.

(Example) Next, the present invention will be described in detail based on an example shown in FIGS. 1 and 2.

FIG. 1 shows the left half as a cross-sectional view of the center, and the right half as a front view, and FIG. 2 is a cross-sectional view taken along the line A--A in FIG. In FIG. 2, the left half of the semi-cured lightweight cellular concrete body 2 is shaded to indicate that it has been cut.

As shown in FIG.
It is divided along the running direction. In the meantime
The thickness is preferably 1.5 mm to 3 mm, particularly preferably about 2 mm. If it is made narrower than this, it becomes difficult to move the wire-like cutting member 1 and the cutting condition of the concrete body 2 becomes poor, and if it is made too wide, the cut concrete body will have many defects.

On the other hand, as seen in FIG. 1, the wire-shaped cutting member 1 is made up of a plurality of generally parallel wire-cutting members, and the upper and lower ends of the plurality of wire-shaped cutting members are generally parallel to each other. It is fixed to an upper fixing frame 5 and a lower fixing frame 6, and the upper fixing frame 5 is located above the concrete body 2, and the lower fixing frame 6 is located below the support base 3. There is.

Further, as shown in FIG. 2, the support stand 3 is supported by support members 4 only at the outer ends of the wire-like cutting member 1 on both sides in the running direction, and between them is a wire-like member fixed at the top and bottom to the frame. The cutting member 1 is movable in the horizontal direction.

Furthermore, the frame body that fixes the wire-shaped cutting member 1 with its upper fixing frame 5 and lower fixing frame 6 can be moved up and down by a mechanism that reciprocates in the up and down direction within a support frame 18 provided on the outside. It is made possible. In the apparatus shown in FIGS. 1 and 2, the upper fixing frame 5 and the lower fixing frame 6 are constructed integrally and are designed to be able to move together. Also,
As a mechanism for vertically reciprocating these fixed frames 5 and 6, the device shown in the drawings is provided with a crank 15 and a rotary plate 16. Of course,
Other means than those shown may also be used as long as the mechanism moves the frame body back and forth in the vertical direction within the support frame 18 provided outside the frame body.

The rotating plate 16 shown in FIGS. 1 and 2 is
It is provided on a support frame 18 that runs along a rail 17, and the fixed frames 5 and 6 are hoisted onto the support frame 18 by a crank 15, and are configured to move as the support frame 18 moves. In addition, a stopper 19 protruding from the support frame 18 is provided to prevent the fixed frames 5, 6 from swinging laterally.

The apparatus of the present invention described above is an apparatus that cuts a semi-hardened lightweight cellular concrete body by moving a wire-like cutting member horizontally in the longitudinal direction of the semi-hardened lightweight cellular concrete body relatively within the concrete body. Yes, even if the concrete body 2 is left still and the wire-shaped cutting member 1 is moved horizontally while reciprocating up and down, the concrete body 2 can be moved horizontally by reciprocating the wire-shaped cutting member 1 at a fixed position. Although it may be moved, the former is preferable in terms of energy efficiency.

The cut concrete body is subjected to other processes (curing process, etc.) from the support base 3 using the method described above, for example.
The next semi-hardened concrete body is placed on the support stand 3, and this concrete body is cut in the same manner as described above.

Even when the apparatus of the present invention, an example of which is shown in this drawing, is used, damage to the cut concrete body during cutting is extremely reduced, and the cut surface of the cut concrete becomes smoother.

(Effects of the Invention) When the device of the present invention is used, unlike when cutting using a conventional device, the cut concrete body has significantly fewer defects, the cut surface is smoother, and the support base can be cut in the longitudinal direction. By creating an uneven structure so that there are parts that come into contact with the concrete body and parts that do not come in contact with the concrete body along the line, not only will the cutting shape be better, but it will also be convenient when moving the cut concrete body to the next process. .
