All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present specification without any creative effort shall fall within the protection scope of the present specification.
With the development of socio-economic, the industry of producing and packaging has to ensure that the devices in its packaging machine system operate well in order to create the greatest benefit for itself. The abnormal state in the generating process can be timely alarmed, so that maintenance personnel or working personnel can carry out timely maintenance, and the influence of errors and faults is avoided as much as possible.
The plug-in detection equipment of the packing machine in the prior art does not have the functions of intelligent monitoring and timely reporting, and can not ensure that maintenance personnel can timely obtain the specific abnormal fault position and the specific abnormal state data of the packing machine. The inspection of the equipment of the packaging machine requires a serviceman to go to the site, the operation process is complicated, and the determination of the abnormality type by the serviceman takes a long time. And the problems of equipment halt and software abnormity cannot be obtained only through the plug-in detection equipment, and the acquisition of various abnormal state data is incomplete. The production efficiency of the packaging machine production line can not be improved while the product quality is ensured.
In order to solve the problems that the abnormal state of the packaging machine is not timely acquired, the process is complex and a friendly interactive display interface is provided for operators in the prior art, the specification provides a monitoring method, equipment and a medium for the packaging machine.
One or more embodiments of the present description may perform the following steps by a server of a packaging machine monitoring service.
The technical solution provided in the present specification is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a schematic flow chart of a method for monitoring a packaging machine according to one or more embodiments of the present disclosure.
The process in fig. 1 may include the following steps:
s101, receiving a state signal monitored by the plug-in detection equipment, and acquiring current parameter data of the state signal.
In one or more embodiments of the present specification, before receiving the status signal monitored by the store detection device, the method further includes:
deploying plug-in detection equipment at a plurality of positions of the packaging machine according to the type of the packaging machine;
the method comprises the steps of setting running speed and parameter data which accord with production requirements through an interactive display terminal, and prestoring the running speed and parameter data in a PLC (programmable logic controller), wherein the parameter data which accord with the production requirements at least comprise: the speed of processing and packaging at each position of the packaging machine and the glue amount of the glue cylinder at each position of the packaging machine.
In one or more embodiments of the present specification, before receiving the status signal monitored by the store detection device, the method further includes:
adding a shutdown monitoring program into the PLC functional program according to the production requirement;
monitoring the working state of each position of the packaging machine in real time through the shutdown monitoring program;
and if the working state of any position of the packaging machine is monitored to have a shutdown, sending a corresponding control instruction to the indicator light and the voice broadcast through a shutdown monitoring program in the PLC functional program.
In one or more embodiments of the present specification, before receiving a status signal monitored by a plug-in detection device and acquiring current parameter data of the status signal, the method further includes:
and adding a mute control instruction in the PLC functional program so as to stop the voice broadcast when a worker maintains the PLC functional program.
In one or more embodiments of the present description, the abnormal state type includes at least one or more of the following: the CCD of the small box is abnormal, the appearance of the sixth surface is abnormal, the appearance of the loose bag is abnormal, the appearance of the strip bag is abnormal, the lifting machine and the outlet are shut down, the glue injection is abnormal, the appearance detection of the third and fifth wheels is abnormal, and the rejection of the eighth wheel is abnormal.
In one or more embodiments of the present description, the shutdown state includes: the program of any position of the packaging machine is exited, the any position of the packaging machine is crashed, and the packaging machine is powered off.
The packaging machine in this specification can select the corresponding packaging machine model according to the production demand, for example: in one or more embodiments of the present disclosure, a ZB45 type hard box and strip packaging machine is selected as the packaging machine. The ZB45 type hard box and hard strip packing machine is a new product made by Chinese tobacco general company introduced from G.D company of Italy in 1992 and 1993 by X2SC-4350/PACK-OWSC cigarette packing machine technology and the latest 'MICRO-II' electric control special technology after the machine is improved and the machine harms the digestion, absorption and development of cigarette making machine company.
In one or more embodiments of the present disclosure, historical abnormal state data of the same model as the packaging machine is obtained through an enterprise database or the internet, and a location where the packaging machine may malfunction or be abnormal is obtained through an empirical model. After the empirical model is analyzed according to the model of the packaging machine, plug-in detection equipment is deployed at a plurality of positions of the packaging machine, so that the appearance detection equipment can accurately receive the packaging machine state data of the most probable fault position, the effective receiving of the packaging machine state signals is improved, and the monitoring effect of the abnormal state of the packaging machine is improved.
Because the degree of grasp of each stage of enterprise development on the production economy is different, in order to intelligently adjust and judge the parameter data of the abnormal state of the packaging machine, the running speed and other parameter data which meet the current production requirement are set and adjusted through the interactive display terminal according to the production requirement of the enterprise. And the setting adjusted by the interactive display terminal is stored in the PLC, so that the PLC sends corresponding control instructions to judge whether the processing speed of each position of the packaging machine is abnormal or not and judge whether the glue cylinder amount of each position of the packaging machine is in the current adjusted normal range or not. Through the adjustment of the interactive display terminal, an enterprise can adjust the corresponding judgment parameters according to the requirements, the complex operation process of operators is facilitated, a relatively friendly operation interface is provided for the operators to perform corresponding adjustment, and the operation time and cost are saved.
Meanwhile, in practical application, problems of equipment halt and software halt of parts of the packaging machine set can be encountered, for example, a program in any position of the packaging machine is exited, a shutdown occurs in any position of the packaging machine, and a shutdown state occurs in the power failure of the packaging machine. In one or more embodiments of the present disclosure, an enterprise may add a shutdown monitoring program to a PLC function program according to a production requirement to perform real-time monitoring on software and hardware shutdown of a packaging unit through the shutdown monitoring program. If the machine is monitored to be stopped in the working state of any position of the packaging machine, a corresponding control instruction is sent to the indicator lamp and the voice broadcast through the PLC functional program. For example: the pilot lamp adopts the three-colour pilot lamp that the model is K50L, appears shutting down when any position of equipment, then PLC function program sends control command for the pilot lamp becomes the yellow light, indicates that operating personnel current position's equipment is in the shutdown state, and controls voice broadcast and carries out audio alert, makes operating personnel can obtain alarm information in real time.
In one or more embodiments of the present disclosure, the shutdown of part of the software and hardware of the device does not interfere with the real-time monitoring of the plug-in device. Therefore, after the shutdown alarm of part of the software and hardware of the equipment, the PLC functional program can still monitor the current state of the shutdown position of the part of the software and hardware, and the problem of repeated voice broadcast on the site is avoided when an operator maintains the shutdown equipment. Before monitoring, a mute control instruction needs to be added into a PLC functional program, so that the equipment for voice broadcasting can stop repeated broadcasting of abnormal states.
It should be further noted that the abnormal state of the packaging machine may include: appearance damage, side ear glue opening, reverse mounting of label paper and the like detected by a small-box CCD (Charge-coupled Device, CCD for short) appearance; the sixth appearance abnormity such as glue opening and damage of the side ear and the like is detected during sixth reinspection; the angle-free folding forming is unqualified, and the strip packet appearance is abnormal, such as outward turning, opening, box missing and the like; no white card or aluminum foil paper, aluminum foil paper outward turning and other three or five rounds of appearance detection abnormity; the loose glass paper, the non-drawn paper and other loose packages have abnormal appearances, the elevator and the outlet are stopped, the glue is injected abnormally, and the eight-wheel rejection is abnormal.
And S102, analyzing the current parameter data through a PLC functional program, wherein the current parameter data are state parameters of each plug-in detection device.
In one or more embodiments of the present disclosure, after obtaining current parameter data collected by the plug-in detection device, an operator performs analysis on the current parameter data by comparing a preset abnormality determination rule with a PLC function program.
S103, if the state parameters of the external hanging detection equipment are judged to be abnormal according to the preset abnormal judgment rule, determining the position of the fault of the packaging machine and the type of the abnormal state; the preset abnormity judgment rule comprises that the speed of processing packages at each position of the packaging machine is lower than a corresponding first preset threshold value, the glue amount of a glue cylinder at each position of the packaging machine is lower than a corresponding second preset threshold value, and whether each position of the packaging machine is in a stop state.
The conveyer belt among the packagine machine is mainly responsible for transporting all kinds of materials, relies on the motor to provide power, needs the conveyer belt to operate continuously under the condition of frequent operation. For clothes falling in the conveyor belt, and wear of the equipment itself, can result in the conveyor belt being too slow or even running down. For example: the reason for the slow speed of the conveyor belt is: the resistance of the conveyor belt is large, and the power supply fails and the parameters are wrong; the reasons for the belt downtime are: motor failure, controller failure, power failure. Possible abnormal conditions of the packaging machine can be obtained by monitoring the operating speed of the packaging machine.
The first preset threshold value is set as an abnormal judgment rule for the speed of processing packages at each position of the packaging machine, so that the running speed of the equipment at the position can be preliminarily judged, and whether the equipment at the position is in an abnormal state or not can be determined. For example: if the running speed of the package is set to 300 packs/minute, the number of packs passing per second is 5 boxes by calculation. At the moment, if the running speed monitored by the plug-in detection equipment is judged to be within 25 boxes/5 seconds after calculation, the detection of false operation or rejection of unqualified products can be considered, namely, the abnormity occurs. Because packagine machine's special encapsulation function, when carrying out capsule injecting glue in the reality is used, probably appear because dry glue shelters from photoelectric switch and makes the interior volume of glue jar use up, lead to pasting a large amount of insecure tobacco bale problem of flowing out. Therefore, in order to avoid the outflow of the product with quality problems, the glue amount of the glue cylinder at each position of the packaging machine needs to be monitored. When an abnormality determination rule is set, the second threshold value of the glue amount needs to be considered to ensure that the glue amount of the glue cylinder at each position is not lower than the corresponding second preset threshold value when the packaging machine works. In addition, in the abnormality judgment rule, the shutdown state of each position of the packaging machine needs to be subjected to parameter setting through setting of relevant parameters, so that the shutdown state of each position of the packaging machine can be monitored in real time through a PLC functional program.
In one or more embodiments of the present description, the method further comprises:
judging the stability of the packaging machine through a preset stability factor;
if the stability factor of the current parameter data is smaller than a preset stability factor, the operation state of the packaging machine is stable;
and if the stability factor of the current parameter data is greater than the preset stability factor, the operation of the packaging machine is overspeed.
When the operation speed of the packaging machine is too fast, the conditions of abrasion of a transmission belt, heating of a motor and the like can be caused. Therefore, in order to reduce the occurrence of the abnormal state, in one or more embodiments of the present disclosure, the operation stability of the packaging machine may be identified by a preset stability factor; if the stability factor is smaller than a preset threshold value, the packaging machine is in a stable operation state, otherwise, the packaging machine is in an abnormal state;
wherein the calculation of the stability factor is known as:
in the formula: vLmaxRepresenting the maximum value of the operation speed of the packaging machine in a certain time period L; vLminRepresenting the minimum value of the running speed of the packaging machine in a certain time period L; vmaxRepresenting a preset maximum value of the operating speed of the packaging machine.
And S104, sending corresponding control instructions to an indicator light and voice broadcast through the PLC functional program to realize monitoring and alarming.
In one or more embodiments of this description, when choosing with K50L pilot lamp, when equipment is unusual, through the control command that PLC functional program sent, the pilot lamp of control relevant position sends ruddiness to control corresponding speaker and carry out voice broadcast, make operating personnel can in time obtain effectual reputation alarm information. When the equipment is stopped and is in a state of waiting for production, the indicating lamp emits yellow light and is matched with corresponding voice broadcasting to give an alarm, so that operators can reasonably distribute technicians to perform corresponding maintenance.
In one or more embodiments of the present specification, after the PLC function program sends a corresponding control instruction to an indicator light and a voice broadcast, the method further includes:
the position of the fault of the packaging machine and the type of the abnormal state are sent to an interactive display terminal through the PLC functional program, so that a worker can obtain information of abnormal equipment through the interactive display interface;
and recording the occurrence frequency and the duration of various abnormal states through the interactive display terminal so as to facilitate the update and maintenance of the packaging machine equipment by workers.
