Problems solved by technology

At present, there are many disadvantages in these two simple pressure detection methods. First, the most important and fatal defect is that it cannot detect leakage or microleakage with a micropore diameter of 50 microns or more above the liquid surface; It is also difficult to accurately adjust the detection pressure and pressure holding time in the process. It can only be grasped and adjusted by repeated trials or operating experience; It is too rough and unscientific; fourth, the cylinder pressure sampling inspection has limitations, slow speed, high labor intensity, etc.
Therefore, these two detection methods have great chance and randomness, and there are also great missed detections, which have left serious safety hazards for the production and use of drugs.

Embodiment 1

[0044] Present embodiment is made of frame 4, program logic controller 3, vertical beam 19, crossbeam 22, extruding fixed plate 17, clamp 23, recycle bucket 2, motor 32 and leak detection parts with brake and deceleration parts.

[0045] The following device of frame 4 has four (also can be six or eight or more) frame feet 1, and its bottom device recycle bin 2, right side device program logic controller 3; The vertical beam 19 is installed on the left side, and the extruding fixed plate 17 is installed in the middle and lower part of the vertical beam 19; The top of the beam 19 and the top device crossbeam 22 of the leak detection part, the device clamp 23 below the crossbeam 22 between the two, see the attached figure 1 shown.

[0046] PLC electronic parts and voice prompt parts are housed in the program logic controller 3, and a leak detection switch is also housed on the panel.

[0047] The leak detection part is made of pressure sensor 18, pressure sensor mounting plate...

Embodiment 2

[0054] This embodiment is a technical solution improved on the basis of Embodiment 1. It is basically the same as Embodiment 1. The difference is that a rejecting device 26 is installed on the upper part of the left mounting plate 9 in the leak detection component. Device 26 is controlled by program logic controller 3, and during action, the operating rod that it protrudes passes after left mounting plate 9, can stretch in the clamp 23.

[0055] During use, when the detected pressure value change value exceeds the preset reference pressure value change range, it is determined that there is leakage in the large transfusion flexible packaging bag or soft bottle 16 to be leak-tested. At this time, the program logic controller 3 Send out unqualified prompt signal, output rejecting command at the same time, drive rejecting device 26, the action lever that rejecting device 26 protrudes will be installed on the fixture 23 and be installed on the large transfusion flexible packaging ba...

Embodiment 3

[0058] This embodiment is a technical solution improved on the basis of Embodiment 2, which is basically the same as Embodiment 2, with the difference that: on the upper part of the left mounting plate 9 in the leak detection component, there is also a detection sensor mounting seat 25, the presence sensor 24 is installed thereon.

[0059] During use, when the leak detection switch is started, the detection presence sensor 24 starts to detect immediately; when the detection presence sensor 24 detects that the large infusion solution soft packaging bag or soft bottle 16 to be leaked exists, the presence signal is sent to the program logic controller 3. The program logic controller 3 outputs instructions to start the motor 32 for detection; when the presence detection sensor 24 detects that the large transfusion flexible packaging bag or soft bottle 16 to be leak-tested does not exist, the absence signal is sent to the program logic control Device 3 sends the large infusion solu...

Abstract

The invention discloses a leakage detection device of large soft transfusion package bags or soft bottles, and relates to the technical field of pharmaceutical packaging machinery. The leakage detection device is composed of a rack (4), a programming logic controller (3), a vertical beam (19), a horizontal beam (22), an extrusion fixed plate (17), a fixture (23), a recycling bin (2), a motor (32) with a brake and a deceleration component, and a leakage detection component. The device has the characteristics of high detection precision, low working intensity, safety and reliability and the like, is suitable for the leakage detection of non-PVC (poly vinyl chloride) film large soft transfusion package bags in various specifications or PP large soft transfusion bottles in various specifications, and can be suitable for the leakage detection of large soft transfusion package bags or soft bottles in various specifications, which are made of other materials.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical packaging machinery, in particular to a leak detection method and a leak detection device for a large transfusion flexible packaging bag or soft bottle. Background technique [0002] In the prior art, the leak detection equipment for non-PVC film soft bag large infusion or PP soft bottle large infusion is a simple pressure detection method, which mainly includes two types: one is online roller pressure detection, and its specific operation and principle are to use a can The rubber wheel that adjusts the distance from the surface of the packaging bag or soft bottle is driven by an electronic speed-regulating motor and rolls over the surface of the packaging bag or soft bottle, so as to distinguish the tightness of the packaging bag or soft bottle with the naked eye; 2. It is a cylinder pressure sampling test. Its specific operation and principle are to use one or more (according to the actua...
