Abstract
A rejection device includes a detection sensor that detects an article, pressurization point setting means for setting an essential pressurization point of the article by using a distance from a front end of the article and a transport time corresponding to a transport speed for each type of the article by a compressed air, a management timer that manages a rejection delay time set by using a delay time from a detection time point when a rear end of the article is detected by a detection sensor to a time point when the essential pressurization point enters a discharge bias section, and rejection command means for inputting a rejection command signal to the rejection unit for a predetermined command time from a time-up time point of the management timer.
Claims10
A rejection device including a transport unit that transports an article and includes a rejection transport passage, and a discharge mechanism unit that responds to an input of a rejection command signal and discharges the article, which enters a specific discharge bias section in the rejection transport passage, to an outside of the rejection transport passage by compressed air, the rejection device comprising:
- a rejection article detection sensor that is disposed on an entrance side of the rejection transport passage and detects the article;
- pressurization point setting means for setting an essential pressurization point of the article when a discharge force to the outside of the rejection transport passage is applied from the discharge mechanism unit by the compressed air, based on a transport time corresponding to a distance and a transport speed from any one end of the article in a transport direction for each type of the article;
- delay time management means for managing a rejection delay time that is set by using a delay time from a detection time point when the one end of the article in the transport direction is detected by the rejection article detection sensor to a time when the essential pressurization point of the article enters the discharge bias section, and;
- rejection command means for inputting the rejection command signal to the discharge mechanism unit for a predetermined command time from a time-up time point of the delay time management means.
An article inspection device comprising:
- a transport unit that transports an article and includes a predetermined transport passage;
- an inspection unit that inspects a predetermined quality state of the article being transported in a predetermined inspection section in the transport passage;
- an air jet type discharge mechanism unit that responds to an input of a rejection command signal and discharges an article which is inspected in a predetermined rejection section in the transport passage to an outside of the transport passage in accordance with an inspection result in the inspection unit;
- and
- a control unit that includes an inspection control unit controlling the inspection unit and a rejection control unit controlling the discharge mechanism unit, wherein
- the discharge mechanism unit includes
- a rejection article detection sensor that is disposed on an entrance side of the predetermined rejection section,
- pressurization point setting means for setting an essential pressurization point of the article when a discharge force to the outside of the transport passage is applied from the discharge mechanism unit by compressed air, based on a transport time corresponding to a distance and a transport speed from any one end of the article in a transport direction for each type of the article,
- delay time management means for managing a rejection delay time that is set by using a delay time from a detection time point when the one end of the article in the transport direction is detected by the rejection article detection sensor to a time when the essential pressurization point of the article enters a discharge bias section, and,
- rejection command means for inputting the rejection command signal to the discharge mechanism unit for a predetermined command time from a time-up time point of the delay time management means in accordance with an inspection result in the inspection unit.
