analysis of the packaging problems

According to the analysis of the above problems, we can know, equipment failure in the measurement error in terms of the problem, should first distinguish is static or dynamic error error, according to the fault situation of the field show, solutions with the working principle of the equipment for the corresponding. Such as:
1, as long as the replacement of a batch of material is to modify a control parameter can be used for normal metering control work, the situation can be summarized as the dynamic error, because the material causes. If the replacement of material varieties are not the same for varieties of PACKAGING materials should be set independently working class group separately control. If it is the same variety replacement of different batches of words should check whether the whether the material in the process of replacement density, liquidity has changed. If there should be to carry on the investigation to the direction of.
2, work of a few times have to re set the control parameters in order to continue to work. This is the phenomenon of dynamic error. Because of the same material the same batch, so generally do not appear to flow density, proportion, change. After exclusion of each component of fault should be to check the measurement mechanism and a bag clamping mechanism of the existence of the phenomenon of sticky material, because of sticky material will make the measurement of materials can not be completely emptied or the next quantitative together when shorting, causing the error.
3, the replacement of varieties of materials will be re quantization calibration to work correctly. This kind of situation can be classified into static error, should check whether the material is different and because the liquidity stress change generated gravity center offset makes the sensor produces a disequilibrium phenomenon of formation of angle difference in enters the measuring barrel, whether it is because of the different materials, the air content resulted from the change of negative air pressure change impact force sensor unbalanced forming angle difference.
4, to replace the material or replace the measurement target value after the emergence of error, the need to re run only after the use of quantitative calibration. This situation will arise static error or dynamic error in two cases.
(1) static error: the static error is caused by different material properties are also different, measuring target value for different amount of accumulation of the material into the measuring barrel is also different, in these cases, the center of gravity of its material enters the measuring barrel also will shift phenomenon and stress point shift to sensor generates angle difference phenomenon.
(2) the dynamic error: because of the different materials, the proportion is different. The air quantity produced by different target value (column) are also different. So these conditions affect the calculation of slow addition amount in advance by the proportion of air volume (volume or column) material weight change and cause measurement error.

Problem shoot for stretch wrapper

For the quantitative stretch wrapping machine and pallet packing machine, packaging scale is the key. We will appear error or big or small in practice, quantitative scale measurement accuracy error. It is divided into static error and dynamic error two phenomena. In the presence of measurement error when we first have to determine which are a kind of error phenomenon, so that we can accurately identify the root causes of failure, solve problems of fundamental. Below, we began to analyze the static error and dynamic error is how to produce, how to deal with:
A static error: static error numerical instrument display and the actual checking value to a. Through the re demarcation of proofreading and then can use normal measurement. The main causes are:
(1): sensor deformation due to sensor after long-term use, metal structure parts of its external appear normal mechanical fatigue phenomena to a certain extent, it will cause deformation, in the deformation process, the resistance change of fission resistance will affect the sensor, the sensor feedback MV this case number will be change, resulting in the original calibration values appear in the proportion calculation error caused by measurement error. At this time, as long as the re quantization calibration can solve problems.
(2) sensor damage: affected by external forces or voltage instability impact factors, damage, due to the special structure of the sensor, we do not have the conditions for on-site repair of sensor. This situation can only replace the sensor.
(3) sensor has angle difference: sensor generates angle difference will influence the balance of fission resistance sensor angle fission occurs angle offset and affect the normal feedback signal caused by static error. Such a situation as long as the re of metering mechanism for the overall level of proofreading, so that each of the sensor angle by pressure balance can solve the problem of fault.
(4) the instrument A/D converter fault, not normal acquisition sensor signal transmission. Under this circumstances, as long as the replacement of the new A/D conversion module can solve the problem.
After removing the instrument A/D conversion module and sensor fault can be determined, is due to external factors caused by static error. From the force balance of mechanism, whether the measuring barrel wall stick material, soft connection material sticking, negative air pressure and other reasons one by one investigation to solve.
Two. The dynamic error: measurement instrument in the complete measurement work after the display of the obtained value is not a value set to target measurement, re setting control parameters can continue after normal use. The main factors causing the dynamic error:
1, the control part:
Control parameter or the basic working parameters to control the setting of the instrument is not reasonable.
Control components in the received command signal whether the instrument output according to schedule the action reaction, whether it will be fast and slow to make the action reaction.
2, the implementation of components:
Cylinder or motor whether because of damaged or overloaded and influence its response speed, power and etc..
Mechanical execution part whetherwear or due to foreign object reader the reasons affecting the response speed. Such as joint bearings because of the lack of lubrication card or dust pollution, the transmission shaft handle due to mechanical fatigue bending deformation caused by etc..
Because no installation index reasonably produce connection error of each component installation will cause the running accuracy of execution unit card effects of movement speed or increase the mechanical fatigue wear parts and reduce the life of the assembly, the impact of the component should have ability to work, affecting the hair Hui should be working efficiency.
3, the material factors:
Whether working operation procedure control parameter or mechanical components are according to the nature of the materials and the set, by the proportion of the material, mobility, density measurement, weight and other characteristics play an important decision. So, the change of dynamic accuracy of different materials affect or big or small. It should according to different varieties of materials or different measurement target value for setting corresponding to the working class to the targeted control parameter and settings in the debugging process.

packing materials and stretch wrapper

Automatic stretch wrapping machine and pallet packaging machine equipment fault type and the solutions:
Packaging equipment failures generally reflected in three aspects: material and product transmission fault, fault and lack of fault product delivery.
1, transmission fault
Transmission fault performance is a system failure, loss of synchronization mechanism operation etc.. This failure is usually due to improper operation, equipment vibration make fasteners loose cause, once a fault occurs, often causing significant damage to equipment, long downtime. Therefore, such a failure to resolutely put an end to happen.
The main measures are strict rules, strengthen equipment maintenance and equipment pre repair, eliminating the trouble in the bud.
2, packing materials and product delivery failure
The main products include fault fault block in the conveying channel. Reasons for this kind of fault reasons in addition to the front about raw and auxiliary materials, itself, and the channel size adjusting device, dirt improper operation channel. When fault occurs, the equipment can be automatic stop control, manual operation, during a security risk.
This type of failure can not be eliminated, therefore, strengthen equipment maintenance and pre repair, improve equipment adjustment precision, improve the staff’s operation level etc..
3, the lack of product failure
Due to the adaptive reasons of raw materials and products transportation and package itself, in the packaging does not cause equipment downtime, but packaged product is missing or increased, then in the post process to layout a plurality of line control, at the same time between between the equipment matching and motion coordination is to adjust to the synchronous state, the working principle of repair personnel should be familiar with the equipment and good adjustment, and do regular revision, do effective work in the fault frequency occurred before the.
Three, fault management:
1, by understanding the causes of the deterioration of equipment technology state: strengthen the technical level of the repair team to enhance the training, to strengthen the exchange of experience in repair, improve the repair level, discuss and carry out technological transformation, technology to eliminate the deterioration of the source.
2, find the weak link of stretch wrapping machine equipment management work, strengthen the equipment environment for attention and improvement, to strengthen the operation staff clean maintenance, repair personnel to strengthen the regular maintenance, adjustment, and from the system to define and supervise the implementation.
3, grasp the equipment failure and wear law; strengthening the recording and analysis of abnormal information of every employee of spot inspection, strengthen staff repair operation record standard statistics, implement the task of the equipment and spare parts to declare the quality inspection work, the full implementation of equipment failure repair personnel housekeeper responsibility, reach its ownership of equipment fault management and mining on the wear law, as far as possible to eliminate faults in the bud, as soon as possible to reduce the equipment failure rate of strength.
4, the formulation of the maintenance cycle, maintenance plan and improve spare parts work; combined with the actual production, according to the daily equipment information, formulate the maintenance cycle, maintenance plan and improve the repair work, make full use of the production gap, other effective use of time for the implementation of production organization in the organization.
5, find out the fault influence on production and economic loss.

One, fully automatic stretch wrapper packaging machine equipment fault reason:
(a), packaging machine equipment production site environment is not good
1 Effect of temperature, high humidity, on the machine (22 – 2 DEG C is the best temperature, relative humidity is 55~60%). If the temperature is higher, the humidity of the environment, change the original fit because parts of the expansion, cause with loose or aggravate the wear, the service life of the machine will be greatly affected, especially made of non-metal materials slide etc.. In parts of relative motion due to deformation are prone to malfunction, serious still can damage some components and parts, and may even cause shutdown repair.
Effects of 2, more dust on the machine. If the stretch wrapping equipment for a long time and more dust in the environment, when the dust component relative motion between components, easy to produce wear, machine movement parts with the loose will cause incoordination.
(two), caused by the fault of packaging materials
Packaging film of poor quality, tension is not up to the requirements, resulting in forming overlapping wideband enough, loose packing, appearance is not up to the requirements.
Packaging film of poor quality, the cutting edge of Mao, heat sealing is irregular in shape, not close to the heat shrinking, shape error and can not accurately conveying in place, the passage blockage, resulting in downtime caused by fault, the transportation.
