Abstract
The invention discloses a detection method and a detection device for a hanging ring of a bottle blowing machine. Particularly, a bottle blank detector and a hanging ring detector are arranged in the direction vertical to the operation direction of an infusion bottle; in the operating process of the infusion bottle, the bottle blank detector is used for detecting time points t1 and t2 corresponding to two endpoints of a bottle blank with a cross section diameter A, which have the same operating direction; the hanging ring detector is used for detecting time points t3 and t4 corresponding to two endpoints of the hanging ring with a cross section diameter B, which have the same operating direction; when the hanging ring detector cannot detect data, the hanging ring in the detected infusion bottle is missed to be buckled; and when a difference value of t3 and t1 is unequal to a difference value of t2 and t4 in the detected data, the hanging ring in the detected infusion bottle is misplaced. The detection method and the detection device have high sensitivity and stable equipment performance. By automatic detection, the labor intensity of workers is reduced, the quality risk is reduced, and the artificial interference cannot be generated in the working process. In the operating process, the device senses the hanging ring on the passing bottle blank through two sensors.

Detailed description of the invention
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
As shown in Figure 1, a kind of bottle blowing machine suspension ring detecting device, comprise a bottle embryo detector 1, suspension ring detector 2 and audible-visual annunciator (not shown), the detection side of two detectors is to all perpendicular to the traffic direction of infusion bottle 3, wherein, bottle embryo detector 1 corresponds to bottle embryo 4, and suspension ring detector 2 corresponds to suspension ring 5.Bottle embryo detector 1 and suspension ring detector 2 are arranged on same vertical plane, and bottle embryo detector 1 and suspension ring detector 2 are all arranged in surveyed area on a production line.
In the present embodiment, bottle embryo detector 1 and suspension ring detector 2 are arranged on the stainless steel stent (adopting the corrosion resistant plate that 1mm is thick) of perpendicular type, the microscler cylindrical void of every side milling one is to install two detectors, and by support installing after automatic pressed on ring machine, namely in surveyed area, detection zone is positioned over to calibrate the position of two detectors and fixing, to make the detection side of two detectors to all perpendicular to the traffic direction of infusion bottle 3 by getting a bottle embryo.
Bottle embryo detector 1 is chosen as optoelectronic switch, and this optoelectronic switch for detecting bottle embryo 4, and records the time point t corresponding to two-end-point of the bottle embryo cross-sectional diameter A identical with traffic direction
1, t
2.Suspension ring detector 2 is chosen as optical fiber inductive head, and this optical fiber inductive head for detecting suspension ring 5, and records the time point t corresponding to two-end-point of the suspension ring cross-sectional diameter B identical with traffic direction

In the present embodiment, optoelectronic switch elected as by bottle embryo detector 1, because suspension ring are comparatively thin, and the optical fiber inductive head that the suspension ring detector 2 detecting suspension ring selects induction zone thinner.
Under normal detection, by program process, can not report to the police under normal circumstances, infusion bottle 3 is in operation, and first end points of bottle embryo cross-sectional diameter A first can trigger optoelectronic switch, and writing time put t by optoelectronic switch
1, optical fiber inductive head detects the time point t corresponding to first end points of suspension ring cross-sectional diameter B successively subsequently
3, suspension ring cross-sectional diameter B the time point t corresponding to second end points
4, last optoelectronic switch detects second end points of bottle embryo cross-sectional diameter A, and puts t writing time
2.Under this detects normally, the detection data of bottle embryo detector 1 and suspension ring detector 2 are all normal, and meet t
2-t
1=t
4-t
3, i.e. the position dislocation-free phenomenon of suspension ring.
Under improper detection, namely occur that the situation without suspension ring or suspension ring dislocation appears in bottle embryo, when suspension ring detector 2 can not detect data, then in the infusion bottle of this detection, suspension ring leak and buckle; As t in the data detected
3-t
1≠ t
2-t
4time, then suspension ring dislocation in the infusion bottle of this detection.When the above-mentioned improper detection of appearance, audible-visual annunciator starts sound and light alarm immediately, and so, operative employee can carry out searching defect bottle embryo and buckle up suspension ring at once.And the time of fire alarming of audible-visual annunciator is adjustable.
In the present invention, utilize the time point t that bottle embryo detector 1 detects
1, t
2, the diameter that can calculate bottle outlet embryo is: (t
2-t
