Trigger device

Abstract

The invention discloses a trigger device which comprises a conveying belt group and photoelectric switches. Ingot-shaped tablets are conveyed on the conveying belt group and provided with bases, the peripheries of the bases are closed arcs, an upper surface and a lower surface are formed on the upper side and the lower side of each base respectively, the upper surfaces of the bases are central projecting convex arcs, the lower surfaces of the bases are abutted to the conveying belt group, a light source transmitter and a light source receiver are arranged on the photoelectric switches and on two sides of the conveying belt group respectively, acute angles are formed among the light source transmitter, the light source receiver and the bases of the ingot-shaped tablets, so that the ingot-shaped tablets pass gaps of the light source transmitter and the light source receiver, joints of the bases and sides of the upper surfaces of the ingot-shaped tablets shield the light source transmitter to trigger the photoelectric switches, so that the photoelectric switches can be triggered when the joints of the bases and the sides of the upper surfaces of the ingot-shaped tablets pass the photoelectric switches by the aid of the acute angles formed by the trigger device and the ingot-shaped tablets, and the photoelectric switches accurately detect the ingot-shaped tablets and generate trigger signals.

Description

technical field [0001] The invention relates to a trigger device, in particular to a trigger device which utilizes a spindle transported on a conveyer belt to cover a photoelectric switch so that the photoelectric switch generates a trigger signal. Background technique [0002] Generally, the surface of the tablet is in the shape of a raised central arc, and the tablet is transported to a processing machine (such as a laser drilling machine) by a conveyor belt for processing during the post-production process. In order to ensure that the processing machine can accurately To process pills, a photoelectric switch is often installed on the conveyor belt, and the pills are used to generate a trigger signal through the trigger device, so that the processing machine can process the pills accurately. However, when the pills are on the conveyor belt, in order to speed up the production process , There is often only a very small gap or even adjacent to each other between the two pill...

[0002] Generally, the surface of the tablet is in the shape of a raised central arc, and the tablet is transported to a processing machine (such as a laser drilling machine) by a conveyor belt for processing during the post-production process. In order to ensure that the processing machine can accurately To process pills, a photoelectric switch is often installed on the conveyor belt, and the pills are used to generate a trigger signal through the trigger device, so that the processing machine can process the pills accurately. However, when the pills are on the conveyor belt, in order to speed up the production process , There is often only a very small gap between two pills or even adjacent to each other, often causing misjudgment by the photoelectric switch, and the setting of the photoelectric switch is limited by the conveyor belt, so that the photoelectric switch cannot accurately detect the pills
