Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device for forming a pattern (or unevenness) on the surface of a lightweight aerated concrete panel (hereinafter simply referred to as a panel).

The panels have excellent heat insulation, light weight, fire resistance, and workability, and are therefore widely used in the construction industry as roofs, floors, exterior walls, and partition materials for private residences, houses with stores, and buildings. However, especially when the panel material is used as an exterior wall material or partition material so that the panel material is exposed, the exterior of the building or the exterior of the partition wall is flat, and it is necessary to change the type of exterior material or construction method. However, it is too monotonous compared to external walls or partition walls made of other external wall materials (aluminum, FRP, PC, brick, tiles, etc.) that can form various patterns or uneven structures. However, this could become an obstacle to further promoting the use of panels in the future.

Conventionally, the method of creating a pattern (or unevenness) on the panel surface is to create an opposite pattern (or unevenness) on the bottom of the panel manufacturing form in advance, and then apply the pattern (or unevenness) on the panel surface at the same time as the panel is formed. Focusing on the method, or the fact that the panel has good workability, we moved a receiving frame to which the panel was fixed in the long and short sides of the panel under the cutter mount with the conical cutter. There is a method of cutting grooves on the panel surface using a conical cutter. but,
In the former method, it is necessary to use an expensive mold release agent so that the molded product can be successfully released from the bottom of the mold during demolding, and it is necessary to select a pattern (or unevenness) that is easy to release from the mold. ) It is necessary to prepare a large number of expensive patterned (or uneven) molds for mass production each time the pattern changes, which not only increases equipment costs but also makes it difficult to store and manage the molds. In the latter method, only groove cutting can be performed, and the pattern or unevenness (hereinafter simply referred to as processing form) is processed by moving the frame base relative to the conical cutter without dividing it into forms that are easy to process. Processing is slow;
The disadvantages were that the processing types were limited, and in addition, only one panel on the receiving frame could be processed, making it unsuitable for mass production.

The present invention was devised to solve the above-mentioned conventional problems, and while conveying a panel in the long side direction, the panel surface is appropriately processed in the long side direction, the short side direction, and the long side direction interrupted process. It is an object of the present invention to provide a lightweight aerated concrete panel surface processing device that can efficiently and reliably apply various processing forms through various combinations.

In the above configuration, the surface of the panel H is processed as follows.

(1) The panel H to be processed is transported onto the receiving section 1 using a transport device such as a hoist or a forklift, and then transported to the processing section 2 in a lying state in the long side direction of the panel by the transport device 11, while the drive device 45
The panel surface is continuously machined by the full-form cutter 48 which is rotationally driven by. After this continuous processing in the long side direction is completed, the processed panel H is
The blade height of the continuous processing device 5 and the interrupted processing device 7 is located at Adjustment mechanism 6
6,85 from panel H' to the knife 65,83
The conveyor devices 21 and 31 convey the released state to the take-out section 3. Further, the next panel H to be processed is carried into the receiving section 1 which has become vacant after the panel H has been transported to the processing section 2 side, and is kept on standby.

(2) When performing continuous machining in the short side direction and/or interrupted machining, the workpiece panel H is conveyed by the conveyance device 21, and the stopper 24 is set upward, and at the same time when the panel H hits the stopper 24, the conveyance device 21 is stopped to position the panel H, and the panel H is fixed by the panel fixing device 25. At this time, the front end position of the panel H is set at the machining start position of the short side direction continuous machining device 5.

Next, the short side direction continuous processing device 5 processes the entire panel surface in several steps starting from the front end side of the panel H to be processed. That is, the overall molding cutter 65, which is rotationally driven by the drive device 64, is moved in the short side direction of the panel by the drive device 60, and also in the long side direction of the panel by the drive device 53 if necessary, and the cutter 65 is used to cut the panel surface into the short side of the panel. Processing is performed continuously in the side direction, and the cutter 65 is returned to its original position after processing. Next, when processing is performed without moving the cutter 65 in the long side direction of the panel, the rack head 57 is detached from the rack rail 55B by the drive device 56, and the fixation of the continuous processing device 5 in the short side direction is released. After machining, a pulse motor or the like is used in the drive device 53 to rotate the pinion 54, move the device 5 a predetermined distance in the direction opposite to the panel conveyance direction, and perform the aforementioned machining again. Since the entire panel surface is processed by repeating the processing several times in this way, the continuous processing device 5 in the short side direction can be compact.

After this continuous machining in the short side direction is completed, when the stopper 24 is retracted and the panel fixing device 25 is released to perform interrupted machining on the panel surface, continuous machining in the short side direction is performed on the rear end side of the panel H to be processed. The device 5 is evacuated. If interrupted machining is not to be performed, the blade 83 is released from the panel H' by the blade height adjustment mechanism 85 of the device 7 and is transported to the take-out section 3 by the conveying devices 21 and 31, and the device 5 is fixed. to return to the original position. After the processing in the processing section 2 is completed and the panel H' is carried out to the take-out section 3, the continuous processing in the long side direction is carried out, and processing and carrying out or carrying out are carried out as described above.

(3) Intermittent machining shall be performed as follows. First, drive device 7
3, the intermittent processing device 7 is moved in the opposite panel transport direction and set at a predetermined position near the front end of the panel H to be processed, and the drive device 75 engages the rack head 76 with the rack rail 55B to fix the device 7. After driving the conical cutter 83 to be rotationally driven by the drive device 82, the drive device 78 lowers the cutter holder 77 to a predetermined position and stops it, and then the drive device 7
5 to separate the rack head 76 from the rack rail 55B, and at the same time, the drive device 73
Then, the interrupted processing device 7 is moved a certain distance in the opposite panel transport direction and stopped, and at the same time as the stop, the rack head 76 is engaged with the rack rail 55B via the drive device 75 to fix the interrupted processing device 7. Raise the blade holder 77 to the normal position. Next, in this state, the intermittent processing device 7 is moved by the drive device 73 to a certain position in the direction opposite to the panel conveyance direction. Naturally, during this movement, the cutter 83 does not process the panel. After moving to a certain position, the drive device 75 again aligns the rack head 76 with the rack rail 55B to fix the interrupted machining device 7, and lowers the blade holder 77 to perform machining again. In this manner, the entire panel surface is machined by repeating the process several times, which combines the driving and stopping of the intermittent processing device 7 and the raising and lowering of the blade holder 77.
For example, an interrupted pattern such as a so-called brick joint pattern is processed.

After the interrupted processing, the interrupted processing device 7 and the short side continuous processing device 5 are returned to their original positions, the stopper 24 is retracted, the panel fixing device 25 is released, and then the panel H' is moved by the conveying devices 21 and 31. is transported to the extraction section 3.

The panel H' sent to the extraction section 3 is hoisted,
Transport it out of the equipment using a transport device such as a forklift.

FIG. 7 shows the processing form obtained on the panel surface by continuous processing in the long side direction and continuous processing in the short side direction. The items shown in a to c in the same figure are made by a plate-shaped cutter as shown in Fig. 6c, and d
The items shown in -g can be processed using a full-shaped cutter as shown in FIG. 6a or a conical cutter as shown in FIG. 6b. In this case, the blade attachment mechanism of the devices 4 and 5 can be further simplified. It has the same effect in that processing can be performed by relative movement between the blade and the panel H.

Figure 8 shows various machining forms in plan and front views, and those shown in A, B, and C of the same figure are obtained only by continuous machining in the long side direction, and those shown in D E, F,
In the case shown in G and H, a conical cutter is attached to the short side continuous processing device 5 which can move in the long side direction of the panel and the short side direction of the panel, instead of a full-form or plate-like cutter, and this cutter is used to continuously process the short side in the short side direction. What is obtained by machining and shown in I and J is a device for continuous machining in the long side direction, a continuous machining device in the short side direction that processes continuous grooves in the short side direction, and a continuous process machine that processes parallel grooves in the long side direction of the panel. This is obtained by using an interrupted processing device that has two rows of two- and three-piece sets of cutters that can be processed in a continuous manner, and the one shown in K is obtained by continuous processing in the short side direction and interrupted processing. It is.

In addition, what is shown in FIG. 8L is an interrupted machining device that is capable of moving a conical cutter in the long side direction and the short side direction, as well as being capable of moving up and down, in addition to continuous machining in the long side direction and short side direction. However, as the processing device, for example, instead of the cutters 62 to 66 provided in the cutter holder 59 of the short side continuous processing device 5, a cutter provided in the cutter holder 77 of the interrupting device 7 is used. It is sufficient to use a type equipped with cutlery 78 to 84.

The various processing mentioned above, especially Fig. 8 E, F, G, H,
The processing of the item shown in L is carried out by each drive device 53, 6.
This can be done easily and reliably by NC control of 0, 78, and 82. Further, the entire apparatus can be controlled by a computer.

In addition, if the length (length in the long side direction), width (length in the short side direction), and thickness of the workpiece panel H are different, the height of the blades of each device 4, 5, and 7 can be adjusted according to the thickness. It can be adjusted by mechanisms 41, 66, and 85. For the length, the number of times of each machining in continuous machining in the short side direction etc. may be increased. Depending on the width, the length of the spacer 49 may be changed and a device sized to correspond to the maximum panel width may be prepared in advance. However, when mass producing products of the same size, it is preferable to use dedicated equipment because it eliminates waste in equipment.

As described above, the present invention provides a short panel that is movable in the long side direction of the panel on the rails provided on both sides of the conveying device and movable in the short side direction of the panel on the rails provided above the conveying device. It is equipped with a continuous processing device in the side direction and an intermittent processing device that is movable in the long side direction of the panel on rails provided on both sides of the conveyance device and has a blade height adjustment mechanism. By moving the apparatus, as described above, the corresponding processing forms can be obtained with high precision on the panel surface. In addition, since it is equipped with a long side continuous processing device located parallel to the short side direction of the panel, and the panel can be processed while being moved by the conveyance device, the corresponding processing form as described above can be obtained on the panel surface. Furthermore, all of the three devices have a blade height adjustment mechanism, and one of the devices can be selected or some of them can be used in combination as appropriate. Therefore, in the process of conveying the panel, by selecting the cutter to be used, it is possible to easily and accurately obtain a wide variety of processing forms on the panel surface. By appropriately selecting and/or combining devices, it is possible to easily and quickly apply desired processing to the panel surface during the panel conveyance process, thereby quickly obtaining a wide variety of processed forms. Furthermore, since the equipment involved in this series of processing can be reliably controlled by NC or the like, it is possible to sufficiently perform panel surface processing easily and at high speed, and the processing accuracy can be improved.
