Claims (1)

[Scope of Claim for Utility Model Registration] 1. A nozzle that spews hot air toward a sheet material conveyance path, a hot air supply path that communicates between the nozzle and the discharge area of a circulation fan, and a suction of hot air spouted from the nozzle by a circulation fan. In a sheet material drying device equipped with a hot air return path leading to a hot air circulation area and a heater disposed in the middle of the hot air supply path, the hot air supply path branches from the downstream side of the heater and communicates with the suction area of the circulation fan. A drying device for sheet material with a standby function, characterized by comprising a hot air bypass path and a distribution control damper that controls the distribution ratio of the hot air distributed to the hot air bypass path and the nozzle. 2. An upper nozzle that spouts hot air toward the upper surface of the sheet material conveyance path, a lower nozzle that spouts hot air toward the lower surface of the sheet material conveyance path, and a nozzle that extends in one line from the discharge area of the circulation fan. A hot air supply path that branches into two paths midway and communicates with an upper nozzle and a lower nozzle, a hot air return path that guides the hot air ejected from the upper and lower nozzles to the suction area of the circulation fan, and a hot air supply path. In a sheet material drying apparatus equipped with a heater disposed in a single-way state of the hot-air supply path, a hot-air bypass path branches from the downstream side of the heater at a single-way state of the hot-air supply path and communicates with a suction area of a circulation fan; 1. A sheet material drying apparatus with a standby function, comprising: a distribution control damper that selectively covers an upstream opening of a hot air bypass path or an upstream opening of a hot air supply path in a two-way state location. 3. A nozzle that ejects hot air toward the sheet material conveyance path, a hot air supply path that communicates with the nozzle and the discharge area of the circulation fan, and a hot air return path that guides the hot air ejected from the nozzle to the suction area of the circulation fan; A plurality of sheet material drying devices each equipped with a heater placed in the middle of a hot air supply path are installed along the traveling direction of the sheet material conveying path, and each sheet material is dried. The device includes a hot air bypass path that branches from the heater downstream side of the hot air supply path and communicates with the suction area of the circulation fan, a distribution control damper that controls the distribution ratio of hot air distributed to the hot air bypass path and the nozzle, and a distribution control damper. and a damper operation tool for operating a damper, and while the sheet material joints sequentially pass through the sheet material conveying path of each sheet material drying device, distribution control of the sheet material drying device through which the sheet material joints pass. A sheet material drying device with a standby function, characterized in that the damper is equipped with a sequential controller that issues a standby operation signal so that the damper is in a standby state in which hot air is distributed only to the hot air bypass path. Material coating line. 4. A nozzle that ejects hot air toward the sheet material conveyance path, a hot air supply path that communicates with the nozzle and the discharge area of the circulation fan, and a hot air return path that guides the hot air ejected from the nozzle to the suction area of the circulation fan; In a sheet material coating run equipped with a sheet material drying device equipped with a heater disposed in the middle of a hot air supply path, the sheet material drying device branches from the downstream side of the heater in the hot air supply path and circulates. It is equipped with a hot air bypass passage communicating with the suction area of the fan, a distribution control damper that controls the distribution ratio of the hot air distributed to the hot air bypass passage and the nozzle, and a damper operation tool that operates the distribution control damper, and is equipped with a A standby device characterized by comprising a collective controller that issues a standby operation signal to a damper operation tool so that the distribution control damper is in a standby position state distributing hot air only to the hot air bypass path in the event of an abnormal state.
