Splicing device and tape detecting method using the same
A splicing device includes a first detection section which detects whether or not the component storage section protrudes downward from the conveyance reference surface; a second detection section which detects the component storage section of the paper tape; a discrimination section which determines whether a tape inserted into the splicing device is the embossed tape or the paper tape based on a detection signal of the first detection section; a first calculating section which calculates a pitch of the component storage section of the embossed tape by using the first detection section in a case where the embossed tape is determined; and a second calculating section which calculates a pitch of the component storage section of the paper tape by using the second detection section in a case where the paper tape is determined.
1. A splicing device which configured to splice an embossed tape in which component storage sections are formed at a constant interval at a lower position than a conveyance reference surface, and a paper tape in which the component storage sections are formed at a constant interval at an upper position than the conveyance reference surface, the device comprising:
a first detection section arranged on respective sides of the conveyance reference surface which detects whether or not the component storage section protrudes downward from the conveyance reference surface, the first detection section including a laser sensor which receives laser light radiated horizontally across the conveyance reference surface;
a second detection section arranged above and below the conveyance reference surface which detects the component storage section of the paper tape;
a discrimination section which determines whether a tape inserted into the splicing device is the embossed tape or the paper tape based on a detection signal of the first detection section;
a first calculating section which calculates a pitch of the component storage sections of the embossed tape by using the first detection section in a case where the discrimination section determines that the embossed tape is inserted; and
a second calculating section which calculates a pitch of the component storage sections of the paper tape by using the second detection section in a case where the discrimination section determines that the paper tape is inserted.
2. The splicing device according to claim 1 ,
wherein the laser sensor is a regressive reflection type laser sensor configured of a sensor main body and a reflection plate.
3. The splicing device according to claim 1 ,
wherein the laser sensor radiates the laser light via a small through groove that corresponds to a minimum protrusion amount of the component storage section of the embossed tape or a minimum gap amount between the component storage sections adjacent to each other.
4. A tape detecting method which is used in a splicing device configured to splice an embossed tape in which component storage sections are formed at a constant interval at a lower position than a conveyance reference surface, and a paper tape in which the component storage sections are formed at a constant interval at an upper position than the conveyance reference surface, the method comprising:
detecting whether or not the component storage section protrudes downward from the conveyance reference surface by a regressive reflection type laser sensor, arranged on respective sides of the conveyance reference surface, that receives laser light radiated horizontally across the conveyance reference surface,
detecting the component storage section of the paper tape by a detection section arranged above and below the conveyance reference surface, and
calculating a pitch of the component storage sections of the embossed tape by the laser sensor.
