Embodiment
The utility model patent provides the impermeability after a kind of can be on automatic packing train line Packaging Bottle being sealed to carry out online detection and judgement, and can seal the device that underproof Packaging Bottle eliminates train line automatically to being judged as, it is to guarantee the indispensable device of packaging seal quality.
The utility model apparatus structure is seen Fig. 1-3, as shown in the figure: it comprises location conveying mechanism 14 on the following table 16 that is installed on the cabinet 1, be installed on the some detection of negative pressure mechanisms 12 on the conveying mechanism 14 of location and the elevating mechanism 2 of detection of negative pressure mechanism, sees Fig. 1.This location conveying mechanism 14 comprises that integral body is disposed across the conveying belt 28 that can move forward and backward on the slideway under the effect of pusher 17, is equipped with on the carrier bar of conveying belt 28 according to the different removable separation locating pieces 15 of detected bottle diameter, and conveying belt 28 is by motor-driven.Relative position place at location conveying mechanism 14 is a mobile protect fence 5, and bottle can be advanced and be parked on the position of requirement one by one.Adjust the suitable requirement that detects of height that elevating mechanism 2 makes detection of negative pressure mechanism 12.Detection of negative pressure mechanism 12 is the metal cylinders that certain wall thickness is arranged, the plane, foundation ring is smooth and anti-gas-leak O-ring seal 13 is housed, the universal thrust structure in spheroid joint is equipped with at the cylindrical shell top, guarantees each detection of negative pressure mechanism like this under the thrust of pusher 8, is convinced with detection platform and contacts in the cylindrical shell bottom surface.Comprise vacuum pump 19, primary diaphragm valve 20, negative pressure air drum 18, secondary diaphragm valve 21 on the gas circuit of this detection of negative pressure mechanism successively, regulate cylinder 7, pressure transducer 11, tertiary membrane plate valve 22 and the 4th diaphragm valve 23; Wherein: pressure transducer 11 connects secondary instrument 10, connects detected cavity 24 and the 4th diaphragm valve 23 external atmosphere between this tertiary membrane plate valve 22 and the 4th diaphragm valve 23.
Testing process during use is: location conveying mechanism 14 and mobile guardrail 5 under pusher 17,4 effects all external contracting put in place, adjust again, tested Packaging Bottle can be put in place smoothly, and aims at one by one with top detection of negative pressure mechanism 12.Bottle (packing material) after finishing sealing process on the packing train line is imported from conveying belt, at this moment the location retaining pin that is placed in the device portal place is indentation, bottle is by only entering this device, the location conveying belt begins to rotate under motor-driven, and each locating piece 15 enters a bottle to be measured bottle to be measured is delivered to the predefined position of detection platform one by one on the conveying belt of location.When bottle to be measured reaches the number (being assumed to be 6) of regulation, the location conveying belt stops operating.Location retaining pin is overhanging, stops follow-up bottle to advance.Location conveying belt 14 and mobile protect fence 5 step back that bottle to be measured is separated is in place on detection platform 3 under pusher 17,4 guiding separately.
Detection of negative pressure mechanism 12 moves down in the promotion of pusher 8, all cover in the metal cylinder each bottle to be measured, because the universal thrust in the spheroid joint of cylinder top, the end face of each cylindrical shell that the anti-gas-leak packing washer is housed can be convinced fully with detection platform contact, detect immediately and begin.Form a negative pressure region rapidly in the detected cavity of electromagnetic membrane sheet valve events, if seal quality is good, the bottle impermeability is good, and the negative pressure of cavity is in the scope of setting, and tested bottle seal is up-to-standard.If seal quality is not good enough, the gas when forming negative pressure in the cavity in the bottle leaks in cavity, and the negative pressure value in the cavity is changed to some extent, and intelligence system judges according to setting in advance whether the quality of sealing is qualified, just lets pass at acceptability limit; If defectively just assert that the position is worked as and reject the cylinder action by instruction when this bottle is sent to before the device for eliminating it is picked out pipeline, finished the operation of online detection airtightness of bottle seal.
The utility model adopts the method for detection of negative pressure in detecting impermeability, equipment is oversimplified greatly, thereby reduced manufacturing expense, and detection speed is fast, detection principle of the present utility model is: diaphragm valve 21 closures, diaphragm valve 20 is opened, and vacuum pump 19 work make the negative pressure value in the negative pressure air drum 18 reach setting.Diaphragm valve 23 closures, diaphragm valve 22 closures, diaphragm valve 21 is opened, the indicated value of pressure transducer 11, for the initial value of system is stored in the intelligence system, diaphragm valve 21 closures, diaphragm valve 22 is opened, and at this moment the indicated value of pressure transducer 11 is the negative pressure end value of regulating in the system in cylinder and the detected cavity 24.(for the impermeability that makes bottleneck detect to improve sensitivity, cylinder is regulated in one of series connection on detected cavity, according to bottle volume difference regulate spatial volume in test chamber total measurement (volume) and the bottle ratio.) intelligence system can be automatically whether declare the impermeability of bottle by the difference of secondary negative pressure value qualified.Detect end diaphragm valve 22 and close, diaphragm valve 23 is opened, and atmosphere enters the detection of negative pressure cavity and closes, mechanism rises, tested bottle is sent detection platform by the location conveying mechanism, the location retaining pin indentation once more of porch, and the bottle that follow-up packing has been sealed begins second batch of detection.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
