Detailed Description
The following describes the present invention with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the moving object detecting mechanism of the present invention includes a base 11, a touch conductive member 12 installed on the base 11 through a rotating shaft in a swinging manner, an inductive switch 13 triggered by the touch conductive member 12 approaching to the touch conductive member, and a return spring 15 for driving the touch conductive member 12 to leave the inductive switch 13 in a reverse direction. The return spring is usually a tension spring hooked on one end of the touch transmitter 12 to make it tend to swing reversely and extend out to sense whether an object passes through the external passage. The touch conduction piece 12 is installed in a swinging mode, when an object to be detected moves past and the free end of the touch conduction piece 12 is toggled, the touch conduction piece can be driven to swing, the object is locally close to the inductive switch 13 and is detected by the inductive switch 13, the reset spring 15 drives the touch conduction piece 12 to return to the original position after the object passes by to wait for next toggling, and the inductive switch 13 feeds back a signal for sensing the passing of the object to the controller so as to finish the detection process. The touch type detection component can detect any transparent and non-reflective objects which cannot be detected by the photoelectric switch, and the applicability is stronger. The non-reflective object is also a physical object, and the physical object can generate a touch action when passing by, so that the detection is more accurate. In addition, the touch conduction pieces 12 with different detection heights can be replaced so as to detect objects with different sizes, so that the mechanism is good in adjustability and adaptability. After being triggered, the inductive switch 13 correspondingly outputs a detection signal to a controller electrically connected with the inductive switch, so that a complete detection and feedback system is formed. The inductive switch is a proximity switch that is triggered to form a feedback signal when a portion of the touch conductor 12 is in close proximity to the proximity switch. The proximity switch can trigger feedback when approaching, and contact pressing is not needed, so that the touch conduction piece 12 has more retreating buffer spaces and a movable space range, and deformation caused by frequent application of pressing force is avoided.
Further, the detection mechanism is located at the side of the moving object moving direction, the touch transmitter 12 has a touch arm 16 extending out of the moving object moving channel, and the touch arm 16 is suspended to monitor the touch of the object when the object passes through.
Preferably, the sensing arm 16 is bent, the back side of the bent portion faces the inductive switch 13, the bent portion is a portion that is close to the inductive switch 13 to trigger the switch, and the swing range of the swing portion is larger in the swing process, so that the conduction triggering is more sensitive.
Specifically, the inductive switch 13 is a reed switch, and the back side of the inductive arm 16 is provided with a magnet facing the inductive switch, and the reed switch is triggered to form a feedback signal by the magnet approaching the reed switch.
The front end of the touch arm 16 is a smooth curved end 18 which is curved towards the moving direction of the moving object, and the smooth end can not block the object and scratch the object when the object passes by.
In order to protect the interior components and dust, the detection mechanism has a housing 19, and the touch sensing arm 16 extends out of the housing 19. The inductive switch 13 may be provided with a push switch 21 protruding from the case 19 to control the activation and deactivation of the inductive switch 13.
In order to avoid jamming of moving objects causing stops and stacks, the touch conductor 12 is a flexible sheet.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
