Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As shown in Figure 1, the present invention proposes a kind of method whether sealing gasket detecting bottle cap is in place, and it comprises the following steps:
S1, the distance of a range sensor, detecting distance sensor to bottle cap being installed the position of sealing gasket is set on the travelling belt assembling sealing gasket, and controller is set is connected with range sensor;
S2, arrange initial parameter on the controller, when not being with sealing gasket according to detection, range sensor and bottle cap are installed the distance L of the position of sealing gasket, arranging initial distance is L, according to the thickness A of sealing gasket, arranges detected parameters A;
When S3, work, controller is M by range sensor detecting distance sensor to bottle cap being installed the distance of the position of sealing gasket, if M > is L-A, then illustrates that bottle cap does not fill sealing gasket, if M < is L-A, then illustrates and bottle cap has filled sealing gasket more.Described range sensor is the common device utilizing light or the distance between pulse detection object and sensor, owing to being prior art, therefore does not describe in detail.
As improvement, the travelling belt identical with range sensor position also establishes a thrust unit, described thrust unit is connected with controller, detected bottle cap do not fill sealing gasket or many dress sealing gaskets time, controller starts thrust unit and is released outside travelling belt by this bottle cap.After adopting in this way, after detecting that the sealing gasket installation of bottle cap is not in place, this bottle cap can be pushed out from travelling belt, can not have influence on the operation installed to by bottle cap on container in subsequent pipeline, automaticity is high, uses manpower and material resources sparingly.
