The footrest 70 is installed in the proximal portion of the base plate 90. The scaffold 70 is installed on the opposite side to the waterjet unit 60, and as the user climbs on the scaffold 70, the interior material 150 is accurately attached to the fixing jig 110. A plurality of second expansion springs 72 are installed in the bottom portion of the scaffold 70, and a push sensor 74 is installed in the bottom portion of the scaffold 70. When the user climbs on the footrest 70, the footrest 70 is pushed down while the footrest 70 overcomes the expansion force of the second expansion spring 72, so that the footrest 70 presses the push sensor 74. The presence of a person on the footrest 70 is detected.

The rotating motor 80 is installed in the vicinity of the base plate 90. A second gear part 82 is installed below the rotary motor 80, and a chain 46 is formed on the first gear part 42 formed on the outer circumferential surface of the second gear part 82 and the rotating plate 40. Is mounted. When the rotary motor 80 rotates, the second gear 82 is rotated by the rotary motor 80, and when the second gear 82 rotates, the second gear 82 is rotated. The first gear part 42 connected through the chain 46 rotates the rotating plate 40. When the rotating plate 40 rotates, the base plate 90 integrally formed with the rotating plate 40 rotates so that the internal stock fixing part 100 installed on the upper surface of the base plate 90 rotates. Therefore, the internal motor 100 and the base plate 90 rotates slowly by the rotation of the rotary motor 80.

In the proximal portion of the base plate 90, a position detecting sensor 98 for detecting rotation of the base plate 90 is installed. The position detection sensor 98 detects this when the base plate 90 that is rotated by the rotary motor 80 rotates a certain amount to stop the rotary motor 80 from rotating. When the rotation motor 80 slowly stops the rotation operation, the piston 134, which is in close contact with the outer circumferential surface of the base plate 90, comes into close contact with the fixing groove 92 while the base plate 90 stops the rotation operation. As the piston 134 is in close contact with the fixing groove 92, the base plate 90 completely stops rotating.

When the base plate 90 stops the rotation operation by the piston 134, the waterjet unit 60 approaches the interior material 150 attached to the fixing jig 110 to cut the interior material 150 according to the set operation. do.

The product detecting sensor 196 is installed near the fixing jig 110. Since the interior material 150 attached to the fixing jig 110 has a different size according to the specification, when the product detection sensor 196 detects the interior material 150, the interior material 150 may simultaneously detect the specifications of the interior material 150. That is, the product detection sensor 196 is provided with a number of detection units corresponding to the type of the interior material 150 to detect the corresponding detection unit according to the size of the interior material 150 to distinguish the type of interior material 150. Will be.

By controlling the waterjet unit 60 according to the specification of the interior material 150 attached to the) to perform a cutting operation corresponding to the specifications of the interior material 150.

The control unit 190 compares and analyzes the signals applied from the position detecting sensor 98 installed near the base plate 90 and the pressure detecting sensor 74 installed on the footing 70 to the footing 70. When the user is located, the rotation motor 80 is controlled to prevent the rotation operation, and if the base plate 90 is rotated by the signal applied from the position detection sensor 98, the rotation of the rotation motor 80 The base plate 90 stops at the set position by stopping the rotation operation.

The control box is provided with a start button 194, and when the user attaches the interior material 150 to the fixing jig 110 and presses the start button 194, the control unit 190 detects this and rotates the motor 80. Rotate the base plate 90 is rotated by the rotation motor 80 is rotated. When the base plate 90 rotates by a predetermined amount, the position detection sensor 98 detects this and applies it to the controller 190, and the controller 190 stops the rotation of the rotary motor 80. When the rotation motor 80 stops the rotation operation, the piston 134 is in close contact with the fixing groove 92 automatically while the base plate 90 stops, and the piston 134 in the fixing groove 92. When the piston sensor 136 is in close contact with the piston sensor 136 provided to the control unit 190 to apply a stop signal to the control unit 190, the control unit 190 to the waterjet unit 60 in accordance with the stop signal applied from the piston sensor 136. Drive to cut the interior material 150 attached to the fixing jig 110 in the set operation according to the signal of the product detection sensor (196).

Water sprayed by the high pressure from the nozzle 62 of the waterjet unit 60 cuts the interior material 150, most of the water generated while cutting the interior material 150 is the base plate ( Water 90 flows down to the upper surface of the base plate 90 flows to the center along the inclined surface formed on the upper surface of the base plate 90 is discharged through the drain hole provided in the lower rotary shaft (114). In addition, the fixing jig 110 is installed to be separated from each other by the separation membrane 104, the high pressure water discharged from the nozzle 62 of the waterjet unit 60 to cut the interior material 150 is a separation membrane 104 ) Is blocked from being splashed by the interior material 150 attached to the other fixing jig 110 attached to the side surface.
