Abstract: PROBLEM TO BE SOLVED: To suppress production of a large amount of defective products and defective coating to a minimum possible extent by providing a means for detecting the amount of a positional deviation which compares the phase of each of fabricating rolls with a reference phase of the fabricating roll. SOLUTION: A material 1 is made to pass through transfer rolls 6, 11 as fabricating rolls by means of a feed conveyor 4 and a carrying conveyor 5. The actually measured number of pulse signals by a rotary encoder 21 from the point of time when a pulse signal S1 by an origin detection sensor 18 is turned ON (detecting an origin mark 17) upto the point of time when a pulse signal S2 by an origin detection sensor 20 is turned ON, is counted. Thus it is possible to determine the amount of deviation of an origin phase between the transfer rolls 6, 11 by comparing the number of pulses previously set at a control device 23 by the conveying velocity V of the carrying conveyor 5 and an intershaft distance between the transfer rolls 6,11 to the actual measurements. When the transfer phase to the material 1 is deviated beyond the tolerance, an abnormality alarm is sounded by an alarm device 24.

Abstract: PROBLEM TO BE SOLVED: To easily and stably supply liquid paint by controlling a paint injecting quantity from an injecting nozzle by means of the supply quantity of a syringe pump. SOLUTION: Liquid paint to the paint injecting nozzle 9 is executed by using the syringe pump 11, packing paint to a variable storing part 10, rotating a motor 6 by reverse rotation, that is, by the rotary number being proper to CW after that and injecting the paint of the variable storing part 10 to the paint injecting nozzle 9 while moving an inner cylinder 2 in the direction of an arrow (b). In this case, the rotary number of CW in the motor 6 is optionally changed so that the paint injecting quantity is controlled. When the rotary number is small, the paint injecting quantity from the paint injecting nozzle 9 is reduced and a paint result becomes light. When the rotary number is large, the paint result becomes dark. Therefore, the rotary number of the motor 6 is minutely controlled so that light and dark painting can be executed.

Abstract: PROBLEM TO BE SOLVED: To provide a desired pattern without generating unintended nonuniformity in concentration or coating even when carry speed fluctuates by jetting paint from a paint jet nozzle corresponding to the relative moving amounts of the paint jet nozzle and a planar material. SOLUTION: The quantity of paint to be jetted out of a paint jet nozzle 3 is controlled by a pump 4. The pump 4 is controlled by a controller 5. Besides, the pump 4 is connected to a paint tank 11. Further, the quantity of paint to be jetted out is set to the controller 5 by an increase/decrease pattern generator 7. In this case, the setting unit of the paint jet quantity is set per unit pulse such as gram/pulse. This pulse is generated from a pulse corresponding to the moving amount of a conveyer 1 of a rotary encoder 6 attached to the conveyer 1. Therefore, the paint jet quantity is set per unit pulse, namely, is set per unit moving amount of a planar material 2 on the conveyer 1. Thus, even when the conveyer carry speed changes, desired paint coating can be provided.

Abstract: PROBLEM TO BE SOLVED: To obtain a production method facilitating the control of a coating quantity, while a spray coating method is used, and being suitable to a planar material having high decorativeness and a recessed and projection surface by changing an ejecting direction of a coating material from a coating material ejecting nozzle, in a production method of building material coating by spraying the coating material. SOLUTION: A fluid nozzle 19 using air as a coating material ejecting direction control means for controlling the direction of an ejecting stream of the coating material is used in the vicinity of the outlet of the coating material ejecting nozzle 2. The fluid nozzle 19 jets pressurized air from a pressurized air source 20 in the direction crossing the ejecting stream direction of the coating material ejecting from the ejecting nozzle 2, and serves to blow off the coating material later for the time ejected from the ejecting nozzle 2 in the horizontal direction, and is preferred to be provided with every each ejecting nozzle 2. Thus, since scattered coating material is blown off with air and is spread, it is not ejected on a surface to be coated and also is only small even though it adheres, and a formation of light and shade and partitioning with a joint can be surely and easily performed.

Abstract: PROBLEM TO BE SOLVED: To precisely produce and reproduce a prescribed fixed pattern and to rapidly, easily and optionally change the pattern to a target pattern in the case of working the pattern into intended various patterns by making a transfer roll dividable in the transfer roll for coating a base material consisting of a plate material. SOLUTION: In the case of dividing the transfer roll in the roll shaft direction, the transfer roll is into six parts of No.1 to No.6. The transfer roll 1 is provided with parts corresponding to sponge parts 1a-6a and core metals 1b-6b. The transfer roll divided into six parts is fixed to a fixed shaft 7 with nuts 8 to be used as an integrated roll. It is important for the shape of the fixing shaft 7 to prevent the occurrence of slippage of all the transfer roll of No.1 to No.6 in the peripheral direction and the fixed shaft 7 has a structure movable in the peripheral direction. In the case of using a serration in the fixed shaft 7, the movement of the transfer roll in the peripheral direction at the time of rearranging is made fine and the fractional rearrangement is performed.

Abstract: PROBLEM TO BE SOLVED: To restrain the generation of a defect product by detecting a shifting amount of a working position in the raw material transport direction and a difference in the working length. SOLUTION: When a raw material 1 is transported to the position of a transfer roll 6 by a transport conveyer 5, the position of a home position mark 13 of the transfer roll 6 is detected by a home position detecting sensor 14, the leading edge of the raw material 1 is detected by a plate leading edge detecting sensor 15, and the rotational amount of the transfer roll 6 and the travel of the transport conveyer 5 are always counted by a rotary encoder 12. That is, the pulses of pulse signals of the rotary encoder 12 from when the pulse signal of the home position detecting sensor 14 is turned on until the pulse signal of the plate leading edge detecting sensor 15 is turned on are counted. The pulse number shows the difference amount of timing from two pulse signals, which corresponds to the shift amount of the transfer position to the raw material 1. When the difference amount exceeds an allowable value, abnormality warning is given by a warning device 17, and accoring to the abnormality warning, correction is made.
