Description

Detailed Description of the Invention

[0001]

The present invention relates to an ALC plate (JIS A
No. 5416 lightweight cellular concrete plate), or a side groove processing apparatus for a concrete plate used for processing the side groove of a square concrete plate of a known cement extrusion molding plate.

[0002]

2. Description of the Related Art The above-mentioned ALC plate or a concrete plate of a cement extrusion molding plate is a rectangular plate body of a required shape which is used by adhering side surfaces 2 of each other (see FIG. 2) and affixing it as an outer wall of a building. Sides 2 that are joined together
A side groove 3 having a required shape for interconnecting is continuously formed over the entire length of the. Then, the side groove 3 is processed by rotating the disk-shaped processing tool 6 having the cutting edge 4 of a required shape and sequentially feeding the ALC plate 1 by a conveyor or the like.
In addition, a side surface groove processing device for sequentially forming the side surface groove 3 is used.

[0003]

SUMMARY OF THE INVENTION The above conventional side surface groove processing apparatus uses the processing tool 6 when the shape of the side surface groove 3 to be processed is changed in the ALC plate 1 or the like of the workpiece being fed.
Since the conversion of No. cannot be performed immediately, the processing productivity is poor and the processing cost becomes high. The present invention provides a side surface groove processing apparatus for a concrete plate, which prevents the above-mentioned drawbacks of the prior art, while preventing the apparatus from becoming large and long and ensuring good side groove processing performance. Is.

[0004]

SUMMARY OF THE INVENTION To solve the above technical problems, a concrete plate side groove processing apparatus of the present invention is "a disk-shaped processing tool for exposing a cutting edge to the side surface of a concrete plate sequentially fed by a conveyor or the like. Having a tool head having
In a concrete plate side surface groove processing apparatus for continuously forming side surface grooves of a desired shape on the side surface by rotation of the processing tool, the tool head is arranged upright on a turntable in a radial manner. , Each of the tool heads is provided with an advancing / retreating mechanism capable of advancing / retreating a required stroke in the radial direction of the turntable, and further, in the turntable, any of the tool heads is stopped and set at a machining position of the drilling process. It has a set lock mechanism ".

[0005]

In the side groove machining device for a concrete plate of the present invention having the above-described structure, a plurality of tool heads are radially arranged on the turntable, and the selected tool heads are stopped and locked at the machining position. The tool cutting edge of the tool head can be set so as to face the side surface of the concrete plate of the workpiece. Therefore, even if the shape of the side groove to be machined on the progressive concrete plate changes, the tool heads corresponding to the shape change of the side groove are preliminarily attached to the plurality of tool heads with different cutting edge shapes. By rotationally converting and setting, it is possible to immediately respond to changes in the processed shape.

Further, since the side groove machining apparatus of the present invention has the above-mentioned advancing / retreating mechanism which allows each of the tool heads to advance / retreat in the radial direction of the turntable, the turntable is rotated to machine the selected tool head. When setting to the position, the tool head is rotated to the retracted position of the advancing / retreating stroke, and it is set to the machining position and then set to the advancing position of the machining point. Interference between the cutting edge and the concrete plate of the work piece can be avoided, and a smooth conversion set of the tool head can be made, and the turning radius can be made smaller so that a small turntable can be used, making the device larger and longer. Never bring.

In order to accurately machine the side groove, the long and heavy concrete plate is sequentially fed, the relative position of the tool head relative to the cutting edge of the machining tool is accurately positioned, and the side groove is precisely machined. Although it is necessary to have a structure in which a reference guide roller for accurately positioning and guiding the side of the processed surface of the concrete plate to be progressively arranged is arranged at a fine pitch, the tool head having the processing tool has a retracted posture by the advance / retreat mechanism described above. Since it is possible to prevent the interference between the reference guide roller and the processing tool that converts the rotation, it is possible to install the reference guide roller at the required position near the processing tool in the processing position. It is possible to ensure a stable and stable relative posture between the concrete plate and the processing tool for processing the groove with high precision. And, since the processing tool that rotates and converts with the turntable interferes with the reference guide roller, the installation position of the reference guide roller is limited, and the relative position of the side surface of the progressive concrete plate and the processing tool may collapse.) .

An advancing / retreating mechanism 9 that moves the side surface 2 of the ALC plate 1 close to or away from the side surface 2 is configured.

Further, in the main body frame 16 through which the outer circumference of the turntable 8 passes, a locking claw at the tip of the operating shaft of the air cylinder 14 is engaged with a locking groove of the turntable 8 and rotationally moved to be selected. Turntable 8 in which the tool head 5 is accurately stopped and set in the processing position 21
Set lock mechanism 17 is provided.

The side groove processing apparatus of the embodiment shown in FIG.
The machining tools 6 having different cutting edge shapes are attached to the individual tool heads 5, and are set in the retracted posture by the advancing / retreating mechanism 9 (the solid line position in FIG. 1). And conveyor 2

When the processing is completed, the next ALC
When the shape of the side surface groove 3 to be machined in the plate 1 is changed, the tool head 5 located at the processing position 21 is returned to the retracted position again and the turntable 8 is rotated to machine the next side surface groove 3. The tool head 5 having the processing tool 6 to be selected is selected, set-locked in the processing position 21, and the same procedure is repeated thereafter, so that the side groove 3 having a different shape is formed on the ALC plate 1 which is sequentially fed. If necessary, it is processed sequentially and continuously.

In the side surface groove processing apparatus of FIG. 1 embodiment, the relative posture between the cutting edge 4 of the processing tool 6 of the tool head 5 at the processing position 21 and the side surface 2 of the processing surface of the ALC plate 1 is accurately and stably maintained.

The tool head 5 having the tool 6 can be selectively set, and when the tool head 5 moves in and out of the processing position 21 by the rotation of the turntable 8, the cutting edge of the processing tool 6 is exhibited in the retracted posture. Four
Is in a state of being withdrawn from the ALC plate 1, so that there is no interference with the ALC plate, the rotation of the tool head 5 can be smoothly performed by the rotation, and the orbit radius of the tool head 5 due to the rotation is small, resulting in a large apparatus size. It does not bring about shaping or lengthening.

By the retracted posture, the tool head 5 can be turned and moved in and out of the processing position 21, so that the interference between the processing tool 6 and the reference guide roller 19 at the time of the rotation conversion is prevented, and the reference guide roller 19 is prevented. The guide roller 19 is arranged at a required position near the processing position 21, and the relative posture between the side surface 2 and the processing tool 6 on the processing position 21 is well ensured, so that the accurate side surface groove 3 can be processed.
