Abstract

PURPOSE:To eliminate malfunction due to ambient dust, etc., by blowing air to a specific position through a differential pressure sensor and a conduit, and detecting whether a body is present or not from the output of the differential pressure sensor which varies according to whether the body is at the specific position or not. CONSTITUTION:Gas such as air from a gas supply source 6 is blown to the specific position through a conduit 8, the differential pressure sensor 4, and a conduit 5. The output of the sensor 4 varies because the passage of the gas is cut off by the body 2 when the body 2 is on the blow-off hole 7 at the specific position of a shooter 1. The output variation of this differential pressure sensor 4 is utilized to detect whether the body 2 is present at the specific position or not. Consequently, malfunction due to ambient dust, etc., is eliminated unlike a photosensor.

2. Description of the Related Art Conventionally, optical sensors and the like have been used to detect whether an object, such as an electronic component, is at a predetermined position on a device or whether it has passed a predetermined position. However, such optical sensors tend to malfunction when surrounding dust or the like adheres to their surfaces, and therefore have the disadvantage of requiring frequent cleaning.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a simplified configuration diagram for explaining a method for detecting the presence or absence of an object according to an embodiment of the present invention. For example, an object 2 such as an electronic part moves on the shooter 1 in the direction of arrow 6 (to the right in FIG. 1).In the method for detecting the presence or absence of an object according to the present invention, it is attempted to detect whether or not the object 2 is present. Shooter 1
A penetrating spray hole 7 is formed at a predetermined position, one end of the conduit 5 is disposed in the spray hole 7, and the other end of the conduit 5 is connected to one end of the differential pressure sensor 4. Furthermore, the other end of this differential pressure sensor 4 is connected to a gas supply source B via a conduit 8, and a gas such as air is supplied from this gas supply source 6. As a result, the gas from the gas supply source 6 is blown to a predetermined position via the conduit 8, the differential pressure sensor 4, and the guide W5. The output of the differential pressure sensor 4 is determined at a predetermined position of the shooter 1,
That is, when there is an object 2 above the blowing hole 7, the gas passage is blocked by the object, so the change occurs. Based on the change in the output of the differential pressure sensor 4, it is detected whether or not the object 2 is present at a predetermined position.

In this way, in the present invention, the differential pressure sensor 4 is exposed to a predetermined position via the conduit 5.8, and the gas from the gas supply source 6 is blown to the predetermined position via the differential pressure sensor 4 and the conduit 5. Since the presence or absence of the object 2 is detected by the change in the output of the differential pressure sensor 4 when the object 2 is in a predetermined position and when it is not,
Unlike conventional optical sensors, there is no malfunction caused by surrounding dust or the like. Furthermore, since the gas is blown from the blowing hole 7 to a predetermined position, the blowing hole 7 will not be clogged with dust or the like.

FIG. 2 is a block diagram corresponding to FIG. 1 for explaining another embodiment of the present invention, and corresponding parts are given the same reference numerals. In the embodiment described above, the spray hole 7 was formed in the chute 1, and the gas was sprayed from below to a predetermined position through the spray hole 7, but in this embodiment, one end of the conduit 5 was directed from above to a predetermined position. Then blow the gas. The distance s1 between the conduit 5 and the object 2 when the object 2 is in a predetermined position as shown by the imaginary line in FIG. is selected as appropriate so that it changes. The configuration of the pond is similar to the previous embodiment.
