  A preferred embodiment of the stone sweeping reversing machine 6 according to the present invention will be described below with reference to the drawings (mainly FIGS. 1 to 4). The present invention sweeps the stone 5 that is no longer necessary without being finally bonded in the manufacturing process of the steel roofing material 1 to which the stone 5 is bonded. In addition, although this invention is implemented similarly about a steel plate wall material, it abbreviate | omits in the following description. Moreover, as the stone grain 5 adhere | attached on the steel plate roofing material 1, although an artificial stone grain is suitable, not only this but a natural stone grain is implemented.

  The stone sweeping reversing machine 6 includes a horizontal piston 61, a horizontal shaft 62, a 90-degree rotating sandwiching body 64, and a 90-degree rotating conveyor 20 on a gantry 60 as main components.

  First, two horizontal pistons 61 that are extendable in the horizontal direction inside and outside the gantry 60 are installed on the gantry 60 (the width in the longitudinal direction is about 210 cm). The horizontal piston 61 is configured to be extendable and retractable by a drive motor (not shown). In addition, a horizontal horizontal shaft 62 is provided on the gantry 60 so as to extend in the longitudinal direction (see FIG. 3).

  On the horizontal shaft 62, an arm portion 63 that is pin-connected by the tip 61a of the horizontal piston 61 is pivotally attached. In addition, a 90-degree rotating conveyor 20 that functions as a normal conveyor on which the steel roofing material 1 is transported and placed and that can be turned 90 degrees downward is also attached to the horizontal shaft 62. Yes.

  That is, as shown in FIG. 3, the 90-degree rotating conveyor 20 is installed at a position immediately above the horizontal shaft 62, and the horizontal state shown in FIG. 1 is changed from the horizontal state shown in FIG. In turn, it can rotate 90 degrees. Thus, the height of the 90-degree conveyor 20 is set to be the same as the height of the adjacent conveyors 2 (see FIG. 5).

  Next, the lower ends 64b of the four 90-degree rotation holding bodies 64 formed in an angle shape are attached to the horizontal shaft 62, and the 90-degree rotation holding body 64 itself is also 90 degrees inward and outward of the gantry 60. It is configured to be rotatable. At the upper end 64a of the 90-degree rotating sandwiching body 64, an upper air clamp 65 located above and a lower air clamp 66 located below are attached.

  In the state where the horizontal piston 61 shown in FIG. 1 is extended, the upper and lower air clamps 65 and 66 are provided on one side surface portion 1B of the steel plate roofing material 1 placed horizontally on the 90-degree rotating conveyor 20. It can be clamped from above and below.

  Further, in the stone sweeping reversing machine 6, a pair of front sensors 67, 67 and rear sensors 68, 68 are installed on the gantry 60 in front of and behind the 90-degree rotating conveyor 20, respectively. This is because when the steel sheet roofing material 1 is transferred onto the 90-degree rotating conveyor 20, it is detected by the front and rear sensors 67 and 68, and the operation of the 90-degree rotating conveyor 20 is temporarily stopped. After the stop, the upper and lower air clamps 65 and 66 are immediately operated.

  A usage example of the above-described stone sweeping reversing machine 6 of the present invention will be described.

  In the left end portion of FIG. 6, the steel plate roofing material 1 is placed on the conveyor 2 in the vertical direction. The two-component mixed adhesive 30 is applied from the two-component mixed adhesive spray device 3 to the upper surface portion 1A, the one side surface 1B, and the other side surface portion 1C of the steel sheet roofing material 1 that immediately moves on the conveyor 2.

  Here, the steel sheet roof material 1 will be described. A steel sheet having a thickness of about 0.4 mm is press-molded to form a roof material 1 having a desired shape. In general, a flat upper surface portion 1A (the length in the longitudinal direction is about 130 cm and the length in the short direction is about 40 cm) and the left and right side surfaces 1B that are respectively connected to the upper surface portion 1A by bending the left and right ends thereof. And the other side surface portion 1C (height is about 20 mm). Although the shapes of the side surface portions 1B and 1C are not limited, in the present embodiment, a case will be described in which one side surface 1B is formed as a vertical surface and the other side surface 1C is formed as a gently inclined surface (see FIG. 9).

  Subsequently, large stone particles 5A are dropped from the first hopper 4A and bonded to the upper surface portion 1A of the steel roofing material 1 to which the adhesive 30 is applied.

  That is, as shown in FIG. 1, as the horizontal piston 61 of the stone sweeping reversing machine 6 contracts, the steel sheet roofing material 1 having the one side surface portion 1B sandwiched between the upper and lower air clamps 65, 66 is 90 Along with the rotary conveyor 20 and the 90-degree rotary sandwiching body 64, it is rotated downward inward of the gantry 6. When rotated up to 90 degrees, the steel sheet roofing material 1 sandwiched between the upper and lower air clamps 65 and 66 is displaced in a vertical state. Then, the stone particles 5 that are not finally bonded do not generate a frictional force between the stone particles 5 that are bonded to the upper surface portion 1A of the steel sheet roofing material 1 and fall at a stretch by their own weight, and the stone sweeps. Is surely done.

  When the stone sweeping operation is finished, when the horizontal piston 61 of the stone sweeping reversing machine 6 is extended, the steel sheet roofing material 1 is rotated upward together with the 90-degree rotating conveyor 20 and the 90-degree rotating sandwiching body 64 ( FIG. 1). Finally, the steel plate roofing material 1 sandwiched between the upper and lower air clamps 65 and 66 is displaced to the original horizontal state. Thereafter, the holding of the side surface portion 1B by the upper and lower air clamps 65, 66 is released.

  Thus, when the 90-degree rotating conveyor 20 is operated and transferred to the next conveyor 2, small particles from the second hopper 4 </ b> B are applied to the upper surface portion 1 </ b> A of the steel sheet roofing material 1 to which the necessary large stone particles 5 </ b> A are bonded. Stone particles 5B are dropped and bonded (FIG. 5). Further, small stone particles 5B are supplied from the second hopper 4B to the small stone setting device 8 via the conveyor 7.

  Subsequently, the steel plate roofing material 1 to which the small stone particles 5B are bonded is inverted 45 degrees upward by the small edge stone attaching device 8, and the stone of the small edge stone attaching device 8 is placed on the side surface 1B of the steel plate roof material 1. After the stone particle 5B is lowered and adhered (see FIG. 4) from the particle placing plate (not shown), it is returned to the original horizontal state.

  After that, the roofing material 1 made of steel sheet in which stone grains 5 are bonded to the upper surface portion 1A and the side surface 1B is reversed 90 degrees downward as described above by the small-sized stone sweeping reversing machine 6 of the same specification, Unnecessary stone grains 5 (especially small stone grains 5B) are dropped without their own weight (see FIG. 2) and then returned to the original horizontal state (see FIG. 5).

  Then, as shown at the right end of FIG. 6, the steel sheet roofing material 1 in the vertical direction y to which the stone grains 5 are bonded is rotated 90 degrees by a horizontal 90-degree rotating machine 10 to change the direction in the lateral direction x. .

This is because the total length of the first drying furnace 11 can be shortened with respect to the specified temperature and time of the drying furnace. In addition, in FIG. 6, the code | symbol 16 has shown the dust collector for dust installed in the vicinity of the conveyor line, and the code | symbol 15 has shown the cooling device, respectively.

  Next, the above-mentioned dried steel plate roof material 1 in the horizontal direction x is allowed to proceed in a right angle direction as it is, and a top coat is applied to the upper surface 1A and the side surface 1B of the dried steel sheet roof material 1 that proceeds in the vertical direction y. The top coat 14 is coated from the spray device 13. This top coat spray device 13 has four nozzles and is a four-head automatic coating method. After that, the steel sheet roofing material 1 is moved on the skewered conveyor 2 (not shown) and transferred to the second drying furnace 12 described below. After all, when the process is viewed from above, the steel sheet roofing material 1 moves on the conveyor 2 arranged in a U-shape as shown in the substantially central portion of FIG. Thus, during this time, the steel roofing material 1 is transferred in the state of (1) landscape orientation x1 → (2) portrait orientation y2 → (3) landscape orientation x3 → (4) portrait orientation y4 → (5) landscape orientation x5. The

  Then, the steel sheet roofing material 1 with the vertical orientation y coated with the top coat 14 is placed in a second drying furnace 12 having four stages of inlets 12A. The top coat 14 is dried from the direction. The second drying furnace 12 is also provided with a plurality of stages of inlets 12A like the first drying furnace 11, and more steel plate roofing materials 1... Are put into the second drying furnace 11 at a time. Shortening is achieved. The processing temperature is 85 to 95 ° C./40 minutes, and the number of processed sheets is 120 sheets.
