Abstract
The utility model discloses a membrane rupture online detection device. The device comprises two sensors opposite to an online film, wherein the two sensors are at a certain distance and respectively fixed on a production line; and the sensors are respectively communicated with a PLC (programmable logic controller) signal on the production. The warning accuracy can be improved by utilizing simultaneous warning of the two sensors, so that the false alarm probability is reduced, and the phenomenon that a single sensor is easily interrupted by a static electric field and sends out a false alarm can be avoided. The membrane rupture detection process is accurate and in time by virtue of the two sensors, so that the production quality is guaranteed, and the production efficiency of the membrane production line is greatly improved. The membrane rupture online detection device is wide in applicability.
Description
Technical field
The utility model relates to a kind of for the device that detects online for rupture of membranes on the film line, belongs to the automatic control equipment field.
Background technology
The online Main Function that detects of rupture of membranes is whether to have fracture phenomena after surveying film forming, in time transmits film forming information, and carries out respective handling by PLC production control line at any time.Because film is in the state of running up in process of production all the time, in the face friction process, can produce stronger static electric field, misoperation occurs in disturb sensor, and simultaneously, electrostatic field can also wear out by acceleration sensor, reduces the usability of sensor; 2. produce in the operation process than high ambient temperature, also accelerated the aging of sensor, make sensor generation misoperation, can produce a large amount of useless films after the misoperation, even make production line occur stopping in emergency, cause larger economic loss, and sensor recovers normal at once after misoperation occurring, the maintenance personal does not have again any problem when checking, to this, the maintenance personal is referred to as soft fault.
Existing respective handling method mainly comprises three kinds: 1. production line resets, and prepares to continue to produce; 2. the inspection sensor is regulated the sensitivity of sensor, avoids or the false alarm reduction phenomenon; 3. change sensor.These three kinds of methods all can not effectively solve the misoperation process of sensor, and self still are subject to the impact that on every side electric field and high temperature exist, and cure the symptoms, not the disease.
How to avoid the generation of similar wrong report situation, under the prerequisite that guarantees production efficiency, fully improve detection accuracy, just become problem to be solved in the utility model.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the utility model aims to provide the pick-up unit that a kind of Detection accuracy is high, can carry out online the breakage of thin film applied detection, to guarantee the processing film quality, enhances productivity.
The utility model is achieved through the following technical solutions:
A kind of rupture of membranes on-line measuring device comprises two sensors relative with online film, and two sensors are at a distance of certain distance, and is separately fixed on the production line, sensor respectively with production line on the PLC signal communication.
A kind of rupture of membranes on-line measuring device described in the utility model, adopt performance identical, two sensors relative with online film are surveyed rupture of membranes, simultaneously, make two sensors at a distance of certain distance, disturb when having avoided same electrostatic field to two sensors, same alarm with two sensors, improve the warning accuracy, reduce misinformation probability, particularly avoided single-sensor to be subject to electrostatic field and disturbed the phenomenon that produces wrong report, the detection process of two sensors, rupture of membranes is surveyed accurately, in time, not only guarantee the quality of production, and greatly improved the production efficiency of film line, had widely applicability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of rupture of membranes on-line measuring device described in the utility model, comprise two sensors 1 relative with online film 3, two sensor 1 models are identical, be separately fixed on the production line, for avoiding the interference of same electrostatic field on the film 3, two sensors 1 are at a distance of certain distance, and respectively by the PLC2 signal communication on wire and the production line, surveying the information that produces can be sent among the PLC2 at any time.
In the work, film 3 high-speed motion on production line, two sensors 1 are surveyed online film 3 simultaneously.According to experience in the past, just to flash once in a while and irregularities such as single-sensor 1, the time of flashing it has been generally acknowledged that less than 1 second single-sensor 1 is to be subjected to the interference of electrostatic field to produce wrong report, PLC2 does not process alerting signal; As when two sensors 1 send alerting signal simultaneously, PLC2 thinks real warning, and the rupture of membranes phenomenon namely occurs, and PLC2 just can tackle mutually production line and adjust and control, and after production line is resetted, continues production run.Owing to be two sensors, 1 same alarms, its probability that wrong report occurs is very little, so can finish in time, exactly the detection to online rupture of membranes, has guaranteed the quality of production and production efficiency.
