Abstract
The invention relates to the field of ring pull can production equipment, in particular to a filling liquid level detection system for aluminum ring pull cans. The filling liquid level detection system comprises a filling machine, the filling machine is connected with a conveying chain channel, a background plate is arranged at the lower end of the conveying chain channel, a CCD camera is arranged at the upper end of the background plate, a shooting light source is arranged on the right side of the CCD camera, the conveying chain channel is connected with a bypass chain channel, a capping machine is arranged at the right end of the conveying chain channel, a chain channel branching plate is arranged between the conveying chain channel and the bypass chain channel, the conveying chain channel and the filling machine are synchronous, the filled ring pull cans are conveyed to the capping machine through the conveying chain channel, the CCD camera shoots can openings, and can opening images are obtained in real time. For objects moving quickly, the number of the moving objects in the industrial camera within the exposure time needs to be considered, the object resolution ratio also needs to be considered, an image detection algorithm based on dynamic threshold values is designed so as to ensure detection precision, and the detection reliability is improved.
Description
Technical field
The present invention relates to pop can production equipment field, be specifically related to the filling liquid level detection system of a kind of aluminium ring pull end.
Background technology
Whether beverage in aluminium pop can is filled is that the height of level of beverage in tank judges by detecting, the detection of current this canned drink liquid level is that the low energy X ray produced according to nuclear energy material passes measured matter, through transmitted intensity with detecting material charge level position and the principle that changes to detect filling liquid material capacity, national departments concerned strengthened the management to radioactive source in recent years, from applying to purchase to detection containing source instrument, daily management, safety, check, scrap its radioactive source to instrument must buy back, its trouble and expense numerous, China only has minority enterprise to adopt this X-ray equipment to detect liquid level, other enterprises are generally by operative employee's eye-observation, when filling speed reach 20000 tanks/hour more than time, just far beyond the limit that human eye can be differentiated, the detection to this index have to be abandoned, therefore need to design the filling liquid level detection system of a kind of aluminium ring pull end.
Summary of the invention
For above problem, the invention provides the filling liquid level detection system of a kind of aluminium ring pull end, devise the image detection algorithm based on dynamic threshold, to ensure the precision detected, improve the reliability detected, whole system has very high practicality and reliability.
To achieve these goals, the technical solution used in the present invention is as follows: the filling liquid level detection system of a kind of aluminium ring pull end, it comprises bottle placer, described bottle placer is connected with conveyer chain road, lower end, described conveyer chain road is provided with background board, described background board upper end is provided with CCD camera, light source of taking pictures is provided with on the right side of described CCD camera, described conveyer chain road is connected with bypass chain road, described carrier chain road right-hand member is provided with capping machine, is provided with chain road plate along separate routes between described carrier chain road and bypass chain road.
Further, described CCD camera lower end is provided with the first proximity switch.
Further, light source lower end of taking pictures described in is provided with the second proximity switch.
Further, described CCD camera is connected with image processing center, and described image processing center adopts IPC-610L industrial computer.
Further, described bottle placer is connected with PLC control system, and described PLC control system comprises PLC main frame, guidance panel, protection alarm module and hardware control module, and described guidance panel, protection alarm module and hardware control module are connected on PLC main frame.
Beneficial effect of the present invention:
Carrier chain road of the present invention and bottle placer synchronous, pop can after filling is sent to capping machine in chain road thus, CCD camera is taken pictures to tank mouth, obtain tank mouth image in real time, for the object of movement fast, need the Moving Objects quantity considering to be within the time shutter in the middle of industrial camera, also need to consider object resolution, light source of taking pictures makes to produce maximum contrast between observed feature and uncared-for characteristics of image, thus be easy to the differentiation of feature, background board coordinates tank mouth light source, reduce the noise that CCD camera obtains picture, reduce the difficulty of image procossing, devise the image detection algorithm based on dynamic threshold, to ensure the precision detected, improve the reliability detected, whole system has very high practicality and reliability, compact conformation, principle is simple, be worthy to be popularized.
