Description

Technical Field

[0001] The invention belongs to the technical field of intelligent food packaging, and in particular relates to a feeding control system of an automatic spicy strip packaging machine. Background Art

[0002] Spicy strips are a type of instant food made from wheat flour or other grain flours. Water, salt, sugar, monosodium glutamate and other food ingredients are stirred into flocs, extruded and puffed at high temperature to form embryos of various shapes, and then appropriate seasonings are added and mixed to make them ready-to-eat convenience foods. Spicy strips need to be packaged and sold after production. Initially, they were mostly installed manually. With the development of technology, automatic packaging machines are used for loading and sealing to improve production and processing efficiency.

[0003] When the existing packaging machine feeds the spicy strips, it feeds according to the set feeding speed. However, during the feeding process, the spicy strips are easy to deviate from the set packaging position. At this time, the machine needs to be stopped and then the position needs to be corrected manually. Its efficiency is low and will affect the overall processing efficiency. In addition, since the spicy strips contain a lot of oil, sugar, salt and other substances, they are easily affected by the temperature and humidity of the environment. For example, in a high temperature and high humidity environment, the spicy strips are easy to become soft and sticky. At this time, according to the original feeding speed, it is easy to cause the spicy strips to stick together, thereby affecting the quality of the spicy strips. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In one embodiment, a feeding control system of a spicy strip automatic packaging machine is disclosed, such as Figure 1 As shown, the control system mainly includes: Feeding unit, monitoring unit, detection unit and execution unit installed on the automatic packaging machine; The feeding unit is used to feed the spicy strips into the corresponding packaging area according to the set feeding speed; The monitoring unit is composed of multiple sensors and is used to obtain relevant parameter information of the spicy strip packaging machine during feeding operation, including the location information of the spicy strips, the temperature information of the workshop, and the humidity information; The detection unit is used to process and analyze the acquired relevant parameter information to determine whether the feeding is abnormal; An execution unit, which is used to execute a corresponding strategy according to the judgment result of the detection unit, and includes a position adjustment unit, a speed adjustment unit and an alarm unit; The position adjustment unit is composed of two electrically controlled manipulators, which are used to correct the spicy strips that are out of position, and the speed adjustment unit is used to adjust the feeding speed of the feeding unit.

[0019] Through the above technical scheme, the present application installs a feeding unit, a monitoring unit, a detection unit and an execution unit on an automatic packaging machine, and firstly feeds the spicy strips into the corresponding packaging area through the feeding unit according to the set feeding speed, and then obtains the position of the spicy strips during each feeding process through the monitoring unit, so as to judge whether the position is abnormal through the monitoring unit, and when the position is abnormal, the position is promptly corrected by the position adjustment unit, so that when the position of the spicy strips is offset, it does not need to be corrected manually, and can be corrected directly, which can greatly improve the processing efficiency; in addition, when the detection unit judges that the position of the spicy strips is abnormal, it can also judge whether the feeding speed is abnormal according to the position of the spicy strips during multiple packaging, and when an abnormality occurs, the feeding speed can be adjusted through the speed adjustment unit to ensure the normal position of the subsequent spicy strips; at the same time, when the detection unit judges that the position of the spicy strips is normal, it analyzes the parameter information within the cycle to judge the potential speed abnormality, so as to timely make a secondary fine-tuning of the spicy strip feeding speed, which can reduce the occurrence of abnormal position of the spicy strips during packaging.

[0020] The working method of the detection unit is: install a position sensor in the corresponding packaging area, and set a standard position point and a reference point in the packaging area. The distance between the standard position point and the reference point is The position sensor obtains the position of the spicy strips from the reference point every time they stop at the packaging area. , so that through the formula Get the absolute value of the deviation ; when , a correction instruction is generated to drive the position adjustment unit to correct the position of the spicy strips, and at the same time, the absolute value of the deviation obtained during the subsequent two spicy strip packaging is obtained. If it also exceeds the preset absolute deviation threshold , a detection instruction is generated, and further detection and judgment are performed according to the detection instruction; The working method of the position adjustment unit is as follows: when a correction instruction is generated, if , then the electric control manipulator of the driving position adjustment unit moves the spicy strips closer to the reference point distance; if , the electric-controlled manipulator driving the position adjustment unit moves the spicy strips away from the reference point distance.

[0021] Through the above technical solution, this implementation provides a specific method for the detection unit to drive the position adjustment unit to adjust the position. First, a position sensor is installed in the corresponding packaging area, and a standard position point and a reference point are set in the packaging area. The distance between the standard position point and the reference point is The position sensor obtains the position of the spicy strips from the reference point every time they stop at the packaging area. , so that through the formula Get the absolute value of the deviation ; Obviously, the larger the absolute value of the deviation is, the more the spicy strips deviate from the packaging position. Therefore, the absolute value of the deviation is different from the preset absolute threshold of the deviation. The comparison is performed with a preset absolute threshold of deviation The size can be determined based on empirical allowable error data. When the position of the spicy strips is exceeded, it indicates that the spicy strips position has deviated from the allowable packaging position, and a correction instruction is generated to drive the position adjustment unit to correct the spicy strips position, so as to ensure that the spicy strips are normal; and when the position is corrected, the spicy strips may exceed the standard position point too much or be far away from the standard position point, so when the correction instruction is generated, if ,like Figure 2 As shown, it means that the spicy strips are located in front of the standard position point at this time. In order to return it to the standard position point, the electric control manipulator of the driving position adjustment unit moves the spicy strips towards the reference point. distance; similarly if ,like Figure 3 As shown, it means that the position of the spicy strip is behind the standard position point, so the electric control manipulator driving the position adjustment unit moves the spicy strip away from the reference point. The distance between the spicy strips can be automatically corrected to ensure normal packaging.

[0022] The method for further testing and judging according to the test instruction is: when the correction instruction is generated for the first time, if , and the subsequent two spicy strips packaging If both are true, a speed reduction instruction is generated, otherwise, an alarm instruction is generated; when the correction instruction is generated for the first time, if , and the subsequent two spicy strips packaging If both are true, a speed increase instruction is generated, otherwise, an alarm instruction is generated; When the speed reduction instruction is generated, the formula Adjust the feed rate to : When the speed increase instruction is generated, the formula Adjust the feed rate to : in, The feeding speed set for the feeding unit, is the first speed conversion coefficient, , as well as These are the absolute values ​​of deviation obtained during the first, second, and third spicy strip packaging.

[0023] Through the above technical solution, when the spicy strips have position deviation, it may be caused by individual reasons or other reasons such as feeding speed. At this time, the absolute value of the deviation obtained during the subsequent two spicy strip packaging is obtained. If it also exceeds the preset absolute deviation threshold , indicating that the position offset is not caused by individual errors, a detection instruction is generated, and further detection and judgment are performed according to the detection instruction. Specifically, when the correction instruction is generated for the first time, if , and the subsequent two spicy strips packaging If both are true, it means that the feeding speed is too fast, then a speed reduction instruction is generated, and the formula Adjust the feed rate to , it can be seen that when the absolute value of the deviation is larger, the power speed that needs to be reduced is also larger. Otherwise, it means that the packaging machine is abnormal, and an alarm instruction is generated to remind the management personnel to check; similarly, when the correction instruction is generated for the first time, if , and the subsequent two spicy strips packaging If both are true, it means that the feeding speed is slow at this time, then a speed increase instruction is generated, and the formula Adjust the feed rate to Otherwise, it means that the packaging machine is abnormal and generates an alarm command to remind the management staff to check. In this way, when the spicy strips position is abnormal, it can be determined whether the position deviation is caused by the feeding speed, and the speed can be adjusted in time to ensure normal subsequent packaging.

[0024] The working method of the detection unit also includes: when no correction instruction is generated, presetting a detection cycle , and every detection cycle , through the formula Get the deviation value , and propose a deviation value Curve function with the number of packaging times x ; So through the formula Determine the coefficient ; when When the secondary adjustment instruction is generated, the speed adjustment unit performs secondary adjustment on the feeding speed of the feeding unit according to the secondary adjustment instruction; in, For the detection cycle The first packaging, For the detection cycle The last packing in For the detection cycle The maximum deviation value within For the detection cycle The minimum deviation value within is the preset deviation comparison value, as well as is the preset weight coefficient, is the preset evaluation coefficient threshold; The method by which the speed adjustment unit performs secondary adjustment on the feeding speed of the feeding unit according to the secondary adjustment instruction is: when , an increase instruction is generated. At this time, the formula At the end of the test cycle, adjust the feed rate to ; when , a decrease instruction is generated. At this time, the formula At the end of the test cycle, adjust the feed rate to ; in, The maximum feed rate that the system allows to adjust. The feeding speed set for the feeding unit, is the second speed conversion coefficient, is the workshop temperature, is the preset standard control temperature, is the workshop humidity, It is the preset standard control humidity.

[0025] Through the above technical solution, this embodiment provides a method and solution for the detection unit to determine whether a potential speed abnormality occurs. Specifically, when no correction instruction is generated, a detection cycle is preset. The time interval can be determined independently based on human experience, and every detection cycle , through the formula Get the deviation value , and propose a deviation value Curve function with the number of packaging times x , so that through the formula Determine the coefficient ;formula In the detection cycle The cumulative change of the deviation coefficient at each packaging. Although the deviation value is within the operating error range at each packaging, it is possible that the deviation value slowly increases within the error range. Therefore, when the formula The larger the value of is, the greater the risk of potential position abnormality is. In the detection cycle The difference between the maximum deviation and the minimum deviation in the period is as follows: The larger the value, the greater the change in the deviation value within the period, and the greater the risk of potential position abnormality. Therefore, a comprehensive analysis is performed through the formula Determine the coefficient , and compare it with the preset evaluation coefficient threshold For comparison, when When the feeding speed is too high, it indicates that the potential possibility of position abnormality is high. Then a secondary adjustment instruction is generated. The speed adjustment unit adjusts the feeding speed of the feeding unit according to the secondary adjustment instruction. Specifically, when , it means that the feeding speed is slow at this time, and the feeding speed needs to be increased to ensure the normal position, then an increase instruction is generated. At this time, the formula At the end of the test cycle, adjust the feed rate to , it can be seen from the formula that when The larger the value, the more speed needs to be increased. Similarly, when feeding spicy strips, it is related to the temperature and humidity of the workshop. For example, when the temperature and humidity When it is larger, the spicy strips will absorb water and the oil will begin to melt. In order to avoid the sticking of the spicy strips, the feeding speed needs to be increased. Therefore, it can be seen from the formula that when The larger the value, the more the feeding speed needs to be increased. In order to ensure the normal operation of the packaging machine, the feeding speed adjustment must have a reasonable range. Therefore, a maximum feeding speed that the system allows to be adjusted is set. Limitation is carried out to ensure the normal operation of the packaging machine; , it means that the feeding speed is too fast and the power speed needs to be reduced to ensure the normal position of the spicy strips. Then a reduction instruction is generated. At this time, the formula At the end of the test cycle, adjust the feed rate to In this way, it is possible to determine whether the automatic packaging machine has potential abnormal feeding speed problems based on the changes in the deviation value within the cycle, so that the feeding speed can be fine-tuned in time to reduce the occurrence of abnormal position of the spicy strips during subsequent packaging. At the same time, the feeding speed can be dynamically adjusted based on environmental factors such as temperature and humidity to ensure the efficiency of the entire packaging operation.

[0026] It should be noted that the first speed conversion coefficient , Second speed conversion coefficient And the maximum feed speed that the system allows to adjust It can be obtained based on the historical data analysis of the relevant models of packaging machines in the big data, and the weight coefficient as well as , preset deviation comparison value , preset evaluation coefficient threshold , preset standard control temperature And preset standard control humidity It can be determined based on historical data combined with empirical data, which will not be elaborated here.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
