Description

  This invention is a process for cutting or cutting holes for mounting holes on panel frames, etc. on the back surface of planar building materials such as ceramics, natural stones, woods, and resins that serve as outer wall materials for outer wall panels, etc. The present invention relates to a planar building material processing apparatus.

Ceramic outer wall materials are used as outer wall panels of detached houses, apartment houses, office buildings and the like. This outer wall surface material is usually attached by hitting a screw to a steel panel frame on the back side from a decorative surface serving as an outdoor surface, or is attached with a metal object by sane processing. In the case of sane processing, only the on-site construction is performed, and the productivity is poor and quality control is difficult. Therefore, the former method is preferable from the viewpoint of industrial production. However, in the structure in which a screw is struck from the decorative surface, a makeup retouching process such as repainting (touch-up) that hides the traces of the screwed part is required. This re-dressing process is an on-site construction and takes time and is difficult to control the quality, which impedes industrialized production.
As an attachment structure of the outer wall surface material that does not require such post-processing, an attachment hole for engaging the latch on the back surface of the outer wall surface material is provided, and this attachment hole is an insertion portion for inserting the head of the latch, The thing made into the shape which consists of a dovetail-shaped slide part following this insertion part is proposed (for example, patent document 1). According to this, the outer wall surface material is arranged so that the mounting hole of the outer wall surface material is inserted into the latch provided on the panel frame at the insertion portion, and the latch is engaged with the slide portion of the mounting hole. By sliding in such a manner, the outer wall surface material can be attached, and post-processing of a number of conventional screw holes becomes unnecessary.

  An example of the outer wall surface material having such a hook structure will be described with reference to FIGS. As shown in FIG. 11, mounting holes 72 are provided on the back surface of the outer wall surface material 71 in a plurality of rows (L1 to L3) in accordance with the pitch of the arrangement of the panel frames. As shown in FIGS. 12 and 13 in an enlarged manner, each mounting hole 72 is formed following a circular insertion portion 72a into which the head portion 73a having a diameter of the latch 73 can be inserted, and the insertion portion 72a. Only the shaft portion 73b of the latch 73 has a slide portion 72b having an opening width that can be inserted. The slide part 72b is formed in a dovetail shape with the bottom of the hole widened, and the head 73a of the latch 73 enters the widened space in the hole (FIG. 13B).

  FIG. 14 shows the relationship between the outer wall surface material 71 and the panel frame 74 in the outer wall panel 70. A latch 73 is attached to a steel panel frame 74 via a heat insulating material 75 such as glass wool board and a base material 76 such as polystyrene board. The latch 73 includes a tapping screw with a drill or the like and penetrates the base material 76 and the heat insulating material 75 and is screwed into the panel frame 74. The latch 73 has a head 73 a having an enlarged diameter and is formed in a dish shape, and protrudes from the surface of the base material 76 by a certain height. In the illustrated example, the head 73a is formed as a separate component from the shaft portion 73b, but the latch 73 may be integrated with the shaft portion 73b. As described above, the outer wall surface material 71 is arranged on the panel frame 74 to which the latch 73 is attached in this manner so that the latch 73 is inserted into the insertion portion 72a (FIG. 13) of each attachment hole 72. The outer wall surface material 71 can be attached by sliding the outer wall surface material 71 so that the head portion 73 a of the latch 73 is engaged with the slide portion 72 b of the attachment hole 72. Thus, since the outer wall surface material 71 is fixed on the back surface, a screw hole penetrating the outdoor surface does not occur, and post-processing is not required.

  The processing of the mounting hole 72 in the outer wall surface material 71 is performed using a router 77 as shown in FIG. The router 77 has a rotary tool 78 for drilling downward. The outer wall surface material 71 is disposed on the processing table 79 so as to be turned upside down and drilled. As the router 77, a multi-axis router having a plurality of rotary tools 78 is used, and a numerical control type is used (for example, Patent Document 2).

JP 2009-249899 A JP-A-11-320549

As shown in FIG. 15, the outer wall surface material 71 is disposed on the processing table 79 so as to be turned upside down and performs hole processing. The router 77 is of a numerical control type, and when the bottom surface of the mounting hole 72 is processed, the router 77 is controlled with high accuracy so as to be positioned at a height determined by a program with reference to the upper surface of the processing table 79.
However, the outer wall surface material 71 which is a building material is generally allowed to have a thickness error of about 10%, and various thicknesses are used within this range. In addition, the thickness of each part of the outer wall surface material 71 varies. Therefore, when the height of the router 77 is controlled on the basis of the upper surface of the processing table 79, the depth D0 of the mounting hole 72 and the depth Da from the deepened portion in the slide portion 72b of the mounting hole 72 to the back surface of the face material are determined. The outer wall surface material 71 varies by the variation a of the plate thickness. Variations in the depths Da and D0 also occur due to unevenness of the back surface position due to warpage of the outer wall surface 71 or the like.

In the building material system, generally, the tolerance of error is large, but in the structure in which the latch 73 is engaged with the mounting hole 72 as shown in FIG. This leads to loose fixing of the outer wall surface 71 to the frame 74 by the latch 73 and inability to attach. For example, if the depth Da to the deepened portion is too shallow, a gap is generated between the head 73a of the latch 73 and the head contact surface 72ba (FIG. 14) constituting the deepened portion of the mounting hole 72. The outer wall material 71 cannot be stably fixed. If the depth Da is too deep, the head 73a that has entered the insertion portion 72a of the mounting hole 72 becomes shallower than the head contact surface 72ba and cannot move to the slide portion 72b. For this reason, an excellent mounting structure as shown in FIG. 14 has been proposed, but it could not be implemented by the conventional processing technique.
In addition, in order to process the outer wall material 71 by reversing the front and back, it is necessary to perform a process of reversing the outer wall surface material 71 on the outer wall panel production line and a process of reversing the front and back again and returning to the original state. There was a problem that the line was complicated.

This processing is, for example, processing of the attachment hole 72 as shown in FIG. The rotation tool 9 for machining is moved in the directions of the three orthogonal axes by moving the movable bed 10 by the spindle moving mechanism 5. Therefore, the plurality of mounting holes 72 in each of the rows L1 to L3 as shown in FIG. 11 are simultaneously processed into the same shape by the plurality of spindle heads 4. During the processing, compressed air is blown from the nozzle 62 in FIG.

  When processing of one row (for example, row L1 in FIG. 11) is completed as described above, the spindle head 4 is retracted downward, the pressing of the face material W by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is released, and then the chuck The chuck 52 is moved together with the mounting base 51, and the face material W is moved so that the part of the row (for example, row L2 in FIG. 11) to be machined of the face material W comes to a predetermined position of the cutter insertion window 22 of the machining table 2. Move. After this movement, pressing by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is performed again, and the processing of the back surface of the face material W by the spindle head 4 is performed in the same manner as described above.

  When machining of all the rows is completed in this way, the spindle head 4 is retracted downward, the pressing of the face material W by the individual pressing mechanism 19 of the upper surface pressing mechanism 3 is released, and the lifting frame 17 is moved to the upper retracted position. Raise. Further, the chuck 52 is raised to the upper retracted position in FIG. In this state, the chain 49a in the discharging mechanism 49 of the unloading mechanism 44 (FIG. 4) is rotated, and the unloading position where the face material W on the unloading conveyor 44 hits the unloading stopper 57b (FIG. 8) by the engagement piece 49b. Pay out. The board | plate material W paid out to the carrying-out position is carried out from this planar building material processing apparatus manually or by the carrying-out apparatus (not shown) attached to this planar building material processing apparatus.

According to the planar building material processing apparatus having this configuration, the surface material W is pressed onto the processing table 2 as described above, and processing by the rotary tool 9 is performed from the pressed back side. Therefore, the face material W is arranged and brought into close contact with the processing reference surface of the face material W that is a workpiece and the device reference surface that is the upper surface of the processing table of the processing apparatus. The processing is performed in a state where the two are in close contact with each other. Therefore, even if the thickness or warpage of the face material W is generated, it can be processed with high accuracy with respect to the processing reference surface of the face material W. In the processing of the mounting hole 52 as shown in FIG. The depths Da and D0 (FIG. 7B) with respect to the processing reference surface can be processed with high accuracy. Although the surface material W is the outer wall surface material of the outer wall panel, per perform drilling for mounting on the back, since it is not necessary to reverse, leading to simplification of the production line of the outer wall panel.

  Further, since the spindle heads 4 are arranged in a row and installed in the movable bed 10, and the spindle head 4 is moved by moving the movable bed 10, the spindle head 4 has the same shape at a plurality of locations with respect to the face material W. Processing can be performed at the same time and processing time is shortened. In the case of an outer wall material or the like of the outer wall panel, a plurality of mounting holes 72 are provided side by side along the panel frame 74, and such simultaneous processing of a plurality of locations arranged in one row can be performed efficiently. Since each spindle head 4 can be individually adjusted with respect to the movable bed 10, the machining holes 72 at a plurality of locations can be simultaneously machined even with respect to the face material W having different arrangement pitches of the machining holes 72.

  Further, since the carry-in / carry-out mechanism 6 is provided, and the face material loading direction positioning mechanism portion 42 and the face material orthogonal direction positioning mechanism portion 43 are provided, the loading and unloading of the face material W can be performed efficiently and the processing of the face material W is performed. Positioning with respect to the table 2 in two orthogonal axes can be performed with high accuracy. Therefore, not only the depth of the face material W with respect to the processing reference surface, but also the dimension in the direction along the processing reference surface can be processed with high accuracy.

  Since the face material carrying-in direction positioning mechanism portion 42 holds the face material W with the chuck 52 and moves it forward and backward, the face material W can be reliably moved without causing a slip or the like. A reference surface S for bringing the end face on the carry-in side of the face material W into contact with the chuck 52 is provided, and the face material W is pressed against the reference surface S of the chuck 52 by the face material pushing mechanism 54. And positioning can be performed with higher accuracy. In addition, since the spindle head 4 is provided with the nozzle 62 that blows compressed air toward the tool tip in the vicinity of the rotary tool 9, the cutting dust in the machining hole can be forcibly scattered outside. Therefore, it is possible to avoid low processing efficiency and processing quality due to residual dust.

  In addition, although the said embodiment demonstrated about the case where hole processing was performed, this planar building material processing apparatus can also perform not only three-dimensional processing but two-dimensional processing, cutting, cutting processing, etc. .
