Abstract: The present invention relates to a tool replacement method for a machine tool, and a tool replacement device therefor. More specifically, according to the tool replacement method, an unclamp detector is installed beside an unclamp set or a main spindle of a machine tool. The unclamp detector outputs an unclamp signal after the unclamp set performs unclamping by colliding with a pull bar of the main spindle, and the unclamp signal disappears when the unclamp set retreats from the pull bar of the main spindle and then, the pull bar comes back to an original position thereof. The tool replacement device is configured to operate and perform replacing a tool whenever the unclamp signal is generated, or to rotate a tool replacement arm so that the tool replacement arm retreats whenever the unclamp signal disappears. Accordingy, a standby time for the tool replacement device and the tool replacement arm to proceed with unclamping and clamping can be effectively reduced to increase the efficiency of tool replacement.

Abstract: The present invention relates to a method for manufacturing a sofa wherein a cushion with plywood and foamed resin is formed on a steel structure. The sofa has been manufactured of wood and resin products, but it is difficult to be manufactured anymore due to the prices for wood being high because of the wood becoming gradually scarce and being almost dependent on imports. Even though the sofa has been made of plywood and plastic, the sofa is excluded from consumers due to the fact of the sofa not being strong enough and the sofa with an elegant shape is a valuable product at a high price. Therefore, a domestic furniture manufacturing field is in a stagnant economic crisis. Fortunately, when a steel structure manufactured by welding steel instead of the wood is formed into the sofa, it is not visible. Also, such sofa is more lightweight and stronger than the wood and facilitates to change the position thereof in a room, such that the sofa can be manufactured as a product suitable for the use. The present invention relates to the manufacturing method applied to professionally produce thereof, wherein if the present invention is generalized, it can be supplied to consumers in a state of being stronger at lower prices than those of existing ones, and allows the demand groups who have been unable to purchase due to the high price to be responsive, thereby having an effect in revitalizing the domestic furniture industry.

Abstract: The present invention relates to a device for predicting a fire early, comprising: a dust sensor for detecting, in real time, dust included in the surrounding air; a dust concentration grasping part for grasping the concentration of dust using the result of dust detection received from the dust sensor; an initial fire grasping part for receiving the concentration of dust consistently through the dust concentration grasping part, comparing the concentration with a reference dust concentration every time the measured concentration of dust is received, and issuing a fire prediction alert if the measured concentration of dust is maintained to be equal to or greater than the reference dust concentration for a set period; a storage part for storing information on the reference dust concentration; a time counting part for starting time counting by the initial fire grasping part when the measured concentration of dust is equal to or greater than the reference dust concentration, and ending the time counting by the initial fire grasping part when the measured concentration of dust is smaller than the reference dust concentration and when a maintenance period becomes the set period; and an alarm part operated by the initial fire grasping part when the maintenance time becomes the set period, thereby issuing a fire prediction alert. Therefore, a user is enabled to respond quickly to a dangerous factor for a fire.
