Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of article stacking, in particular to a blow molding product stacking detection method and system, a terminal and a storage medium. BACKGROUND

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. According to the parison manufacturing method, blow molding can be divided into extrusion blow molding and injection blow molding. The newly developed ones are multi-layer blow molding and stretch blow molding. The products made by blow molding equipment are collectively referred to as blow molding products, such as bottles, cans, some baby products, and sports products, etc.

[0003] The current way of stacking blow molding products is to directly stack the blow molding products after boxing, and then monitor the stacking position of the box during stacking to determine whether the stacking is correct.

[0004] The process from completing boxing to stacking is also a step of stacking blow molding products, but in the current process, there is a lack of corresponding detection means, which may cause defective products in the boxing process, may cause unstable stacking of the box, and thus may affect the quality of the stacking. SUMMARY

[0005] In order to better detect the boxing quality of blow molding products and as far as possible to reduce the possibility of unstable stacking of the box due to boxing problems, the present application provides a blow molding product stacking detection method, system, terminal and storage medium.

When the current weight is greater than the weight threshold, it is proved that there may be foreign matter in the box. At this time, the foreign matter warning prompt information is acquired, so as to facilitate the timely inspection of the box. When the current weight is less than the weight threshold, whether there is a larger space in the box can be determined by judging whether the current decibel value exceeds the preset decibel value. If it exceeds, it means that the space in the box is larger. At this time, the blow molding product missing prompt information is acquired, prompting the relevant personnel that there is a missing blow molding product in the box. If it does not exceed, it is proved that the weight of the generated blow molding product may be insufficient, which proves that the blow molding equipment may be abnormal. At this time, the blow molding equipment abnormal prompt information is acquired. Therefore, the quality of the blow molding product in the box can be better detected, and the possibility of unstable stacking of the box due to the problem of the box can be reduced as much as possible.

[0035] If yes, it is determined that the blow molding work is in the end stage;

[0036] If no, it is determined that the blow molding work is not in the end stage.

[0037] By adopting the above technical solution, whether the blow molding work is in the end stage is judged according to the material progress, so as to obtain insufficient material prompt information or blow molding equipment abnormal prompt information, which can further determine the cause of the abnormal packaging, and then facilitate the relevant personnel to investigate the cause, and as far as possible to ensure the safety and stability of subsequent stacking.

[0038] As a preferred, it further comprises:

[0039] Obtaining the stacking height of the blow molding product;

[0040] Judging whether the stacking height meets a preset height;

[0090] The following will be described in detail below with reference to the accompanying Figures 1 to 8 The present application will be further described in detail.

[0091] An embodiment of the present application discloses a blow molding product stack detection method.

[0092] Reference Figure 1 The blow molding product stack detection method comprises:

[0093] S1. Acquire the current blow molding product packing weight as the current weight;

[0094] S2. Determine the size relationship between the current weight and the weight threshold value;

[0095] S3. If the current weight is greater than the weight threshold value, acquire the foreign matter warning prompt information;

[0096] S4. If the current weight is less than the weight threshold value, acquire the current decibel value when moving the box containing the blow molding products;

[0097] S5. Determine whether the current decibel value exceeds the preset decibel value;

[0098] S6. If it exceeds, acquire the blow molding product missing prompt information;

[0099] S7. If it does not exceed, acquire the blow molding equipment abnormality prompt information.

[0100] Specifically, when the blow molding product packing is completed and needs to be stacked, the current blow molding product packing weight is acquired as the current weight, that is, the weight after the blow molding product is packed is acquired, and the acquisition method can be obtained by measuring through a weight sensor, for example, when the packed product is transported through a conveyor belt, the weight sensor located below the conveyor belt can be measured. Of course, in actual application process, it can also be measured by other ways.

[0101] Then determine the size relationship between the current weight and the weight threshold value, that is, compare the current weight with the weight threshold value, wherein the weight threshold value is the sum of the weight of the box when the current blow molding product is packed enough and the weight of the blow molding product, that is, the rated weight of the packed blow molding product.

[0102] If the current weight is equal to the weight threshold, it proves that the blow molded products in the box are normal, and no additional operation is needed at this time. If the current weight is greater than the weight threshold, it proves that there is a high probability of foreign matter mixed in the box during the boxing process, thereby causing the current weight to become larger, so at this time, the foreign matter warning prompt information is obtained, and the information is sent to the display device, such as a display screen or a terminal device with a display screen of the relevant staff, which can prompt the relevant personnel to check and reject the boxed products in time.

[0103] If the current weight is less than the weight threshold, it proves that the blow molded products in the box may be missing at this time, so in order to further determine the reason, the current decibel value when the box containing the blow molded products is obtained at this time, for example, the current box can be grabbed by a mechanical hand and shaken to a certain extent, and then the decibel value when the box is shaken, that is, the current decibel value, is detected through the audio sensor or other detection device arranged on the mechanical hand.

[0104] Then it is judged whether the current decibel value exceeds the preset decibel value, because when the number of blow molded products in the box is sufficient, the distance between the blow molded products and the box is relatively compact, and at this time, shaking is not easy to produce a larger sound, so the decibel value is also relatively low. Therefore, by judging whether the current decibel value exceeds the preset decibel value, it can be determined whether the blow molded products are missing, of course, the preset decibel value can be set according to the actual situation, or the maximum decibel value emitted after the box is shaken when the number of blow molded products in the box is sufficient, which is obtained through experiment, as the preset decibel value.

[0105] When the current decibel value exceeds the preset decibel value, it is highly probable that the blow molded products in the box are missing, therefore, the blow molded product missing prompt information is obtained and sent to the corresponding display device, so as to remind the relevant staff to check in time and reject the corresponding box, so as to ensure the stability of the stress of the stacked box as much as possible and ensure the quality of the stacking as much as possible.

[0106] If the current decibel value does not exceed the preset decibel value, it is highly probable that the blow molding equipment for producing blow molded products may have an abnormality at this time, causing the blow molded products to be thinned, resulting in insufficient quality of the blow molded products produced, therefore, at this time, the blow molding equipment abnormality prompt information is obtained, so as to prompt the staff to repair the equipment in time.

[0107] Therefore, the quality of the blow molding product produced subsequently can be guaranteed as much as possible, the stability of the box after packing can be guaranteed as much as possible, the packing quality of the blow molding product can be better detected, the defective product can be avoided as much as possible in the process of packing, that is, the quality of the packed box is unqualified, the possibility of unstable stacking of the box due to the packing problem can be reduced as much as possible, and the stacking quality can be guaranteed as much as possible.

[0108] With reference to Figure 2 Further, in order to improve the accuracy of judgment, in another embodiment, before the step of acquiring the blow molding equipment abnormal prompt information, the method further comprises:

[0109] S11. Acquire the packing weight of the blow molding product without weighing as the packing verification weight;

[0110] S12. Determine whether the packing verification weight and the current weight are the same;

[0111] S13. If not, determine whether the packing verification weight matches the weight threshold;

[0112] S14. If yes, do not acquire the blow molding equipment abnormal prompt information;

[0113] S15. If no, execute the step of acquiring the blow molding equipment abnormal prompt information;

[0114] S16. If yes, execute the step of acquiring the blow molding equipment abnormal prompt information.

[0115] Specifically, before the step of acquiring the blow molding equipment abnormal prompt information, acquire the packing weight of the blow molding product without weighing as the packing verification weight, that is, acquire the weight of the box behind the box corresponding to the current packing weight, and the acquisition method is the same as that of the current weight.

[0116] Then, determine whether the current weight and the packing verification weight are the same, that is, whether the blow molding product packed subsequently is also insufficient in weight. If yes, it is proved that the blow molding product produced subsequently also has the condition of insufficient weight, at this time, it can be further determined that the equipment is abnormal with high probability, therefore, at this time, the step of acquiring the blow molding equipment abnormal prompt information is continued to be executed.

[0117] If the packing verification weight and the current weight are not the same, at this time, it cannot be determined whether the packing verification weight is also abnormal, therefore, in order to further determine, at this time, it is determined whether the packing verification weight matches the weight threshold, so as to determine whether the packing verification weight is normal.

[0118] If the case verification weight matches the weight threshold, that is, the case verification weight is equal to the weight threshold, of course, when judging that the two are equal, there can be a certain error interval, if the difference between the two is within the error interval, it is considered equal, otherwise it is not equal. At this time, it is proved that the case verification weight is normal, that is, the weight of the blow molded product produced later is qualified, therefore, at this time, it is not necessary to obtain the blow molding equipment abnormal prompt information.

[0119] And if the case verification weight does not match the weight threshold, it proves that the blow molded product produced later indeed has the problem of unqualified weight, which proves that the blow molding equipment has certain production problems, therefore, the step of obtaining the blow molding equipment abnormal prompt information is continued to be executed, so as to facilitate the prompt to the staff and timely maintenance of the equipment, so as to ensure the stability of the subsequent article stacking as much as possible.

[0120] Of course, in another embodiment, when obtaining the case verification weight, a plurality of case verification weights can be obtained, and it is judged whether all the case verification weights match the weight threshold, if none of them matches, the step of obtaining the blow molding equipment abnormal prompt information is executed. If there is a matching case, and the number of matches is greater than a preset number, the step of obtaining the blow molding equipment abnormal prompt information is not executed.

[0121] Referring to Figure 3 Further, in order to further determine the cause of the abnormality, in another embodiment, when the current decibel value does not exceed the preset decibel value, further comprising:

[0122] S21. Obtain the material usage progress of the blow molding equipment;

[0123] S22. Determine whether the blow molding work is in the end stage based on the material usage progress;

[0124] S23. If yes, obtain the material shortage prompt information;

[0125] S24. If no, obtain the blow molding equipment abnormal prompt information.

[0126] Specifically, when the current decibel value exceeds the preset decibel value, the material usage progress of the equipment is obtained at this time, the obtaining method can be obtained by detecting the sensor arranged in the hopper of the blow molding equipment, or the material usage scale change of the hopper can be observed by the arranged camera, so as to determine the material usage progress.

[0127] Then determine whether the blow molding work is in the end stage according to the material usage progress, the specific method can be to determine whether the material usage progress reaches the preset progress, that is, to determine whether the material in the hopper drops to the preset scale, if it reaches, it proves that it is in the end stage, that is, it means that the current blow molding work is about to be completed, otherwise, it proves that it is not in the end stage.

[0128] When the blow molding work is in the ending stage, the weight of the blow molded product produced at this time is insufficient, which may be caused by insufficient material in the hopper. Therefore, the insufficient material prompt information is obtained at this time, so as to prompt the relevant personnel, and sufficient material is added in the subsequent production process.

[0129] When the blow molding work is not in the ending stage, it proves that the insufficient material does not cause the weight of the blow molded product produced at the last stage to be insufficient. Therefore, it is proved that the blow molding equipment is abnormal at this time, so the blow molding equipment abnormal prompt information is obtained at this time.

[0130] In the above manner, the cause of the weight abnormality can be further determined, so as to remind the relevant personnel to timely investigate and solve the corresponding problems, to ensure the stability of the quality of the subsequent blow molded product production as much as possible, and to ensure the stability of the box after the product is boxed, so as to improve the stacking quality of the blow molded product as much as possible.

[0131] Reference Figure 4 In order to better determine whether the blow molding work is in the ending stage, in another embodiment, whether the blow molding work is in the ending stage is determined based on the material progress, comprising:

[0132] S31. Obtain the time when the material progress is equal to the preset progress as the record time;

[0133] S32. Obtain the current time;

[0134] S33. Obtain the record duration based on the current time and the record time;

[0135] S34. Determine whether the record duration exceeds the duration threshold;

[0136] S35. If it exceeds, it is determined that the blow molding work is in the ending stage;

[0137] S36. If it does not exceed, it is determined that the blow molding work is not in the ending stage.

[0138] Specifically, the time when the material progress is equal to the preset progress is obtained as the record time, that is, the time when the material in the hopper drops to the preset scale is recorded. Then the current time is obtained, which can be obtained by a timer, and of course other ways can also be used.

[0139] Then, the record duration is obtained according to the current time and the record time, that is, the value obtained by subtracting the record time from the current time is the record duration. Then determine whether the record duration exceeds the duration threshold, wherein the duration threshold is the duration when the material in the hopper from the preset scale to completely run out when the equipment is working normally.

[0140] If the recording duration exceeds the duration threshold, it is determined that the blow molding work is in the end stage; if the recording duration is less than the duration threshold, it is determined that the blow molding work is not in the end stage. Thus, by the size relationship between the recording duration and the duration threshold, it can be further determined whether the blow molding work is in the end stage, and the accuracy of the judgment can be improved.

[0141] Referring to Figure 5 In order to ensure the quality of the stacking as much as possible, in another embodiment, when the blow molded products after boxing are stacked, further comprising:

[0142] S41. Obtain the stacking height of the boxed blow molded products;

[0143] S42. Determine whether the stacking height of the boxed blow molded products meets the preset height;

[0144] S43. If not, obtain the stacking abnormality prompt information.

[0145] Specifically, the stacking height of the boxed blow molded products can be obtained by calculating the shooting ratio of the camera, of course, other ways can also be used, such as measuring by a laser range finder.

[0146] Then, it is determined whether the stacking height of the boxed blow molded products meets the preset height, i.e., whether the stacking height of the boxed blow molded products is greater than or equal to the preset height, so as to determine whether the space is fully utilized in the stacking process of the boxed blow molded products. If the stacking height of the boxed blow molded products meets the preset height, it proves that the space is fully utilized, and no further operation is needed at this time.

[0147] If the stacking height of the boxed blow molded products does not meet the preset height, it proves that the space is not fully utilized at this time, so the stacking abnormality prompt information is obtained at this time, so as to remind the relevant staff to adjust the stacking, and thus to ensure the quality of the stacking as much as possible.

[0148] Referring to Figure 6 However, in different application environments, due to different forces on the box, the stacking height may not meet the preset height, therefore, in another embodiment, before obtaining the stacking abnormality prompt information, further comprising:

[0149] S51. Obtain the maximum bearing capacity of the box containing the blow molded products;

[0150] S52. Obtain the vertical stacking number under the stacking height of the boxed blow molded products;

[0151] S53. Obtain the rated weight of the boxed blow molded products;

[0152] S54. Obtain the current bearing capacity of the lowermost box based on the vertical stacking number and the rated weight of the boxed blow molded products;

[0153] S55. Determine whether the current load is less than the maximum load;

[0154] S56. If not, do not perform the step of obtaining the stacking abnormality prompt information;

[0155] S57. If yes, perform the step of obtaining the stacking abnormality prompt information.

[0156] Specifically, before obtaining the stacking abnormality prompt information, the maximum load of the box containing the blow molded product is obtained, and the obtaining method can obtain corresponding experimental data through experiments and store them. Then, the number of vertical stacks at the stacking height is obtained, that is, the number of vertical stacked boxes when the stacking height does not meet the preset height. Of course, the number here is only the number of the first row in the column.

[0157] Next, the stacking rated weight of the blow molded product is obtained. Of course, the rated weight can be specifically set according to different blow molded products. The stacking rated weight is the sum of the weight of all blow molded products in the box and the weight of the box under normal circumstances.

[0158] Then, the current load of the lowermost box is obtained according to the number of vertical stacks and the stacking rated weight. For example, the number of vertical stacks is 10, and the stacking rated weight is 2 kg. Then the current load of the lowermost box is 9 times 2, which is 18 kg.

[0159] Next, it is determined whether the current load is less than the maximum load. For example, the maximum load of the box is 20 kg, and at this time 18 kg is less than 20 kg. Therefore, when the current load is less than the maximum load, it is proved that the box can still be stacked at this time, that is, the space can not be fully utilized. Therefore, at this time, the step of obtaining the stacking abnormality prompt information is continued to be performed.

[0160] When the current load is not less than the maximum load, it is proved that the lowermost box has reached the limit of weighing at this time. Therefore, the box cannot be stacked at this time, and therefore the step of obtaining the stacking abnormality prompt information does not need to be performed at this time, thereby further improving the accuracy of the determination.

[0161] Of course, further, in another embodiment, when the current load is not less than the maximum load, it can be divided into two cases: when the current load is greater than the maximum load, and when the current load is equal to the maximum load. When the current load is greater than the maximum load, the stacking excess prompt information can be obtained, thereby reminding the staff to reduce the stacking amount. When the current load is equal to the maximum load, no step needs to be performed.

[0162] Reference Figure 7Further, in another embodiment, before the step of acquiring the stack abnormal prompt information is performed, further comprising:

[0163] S61. acquiring an added test weight based on the current bearing weight and the case rated weight;

[0164] S62. judging whether the added test weight is greater than the maximum bearing weight;

[0165] S63. if yes, not performing the step of acquiring the stack abnormal prompt information;

[0166] S64. if no, continuing to perform the step of acquiring the stack abnormal prompt information.

[0167] Specifically, before the step of acquiring the stack abnormal prompt information is performed, the added test weight is acquired based on the current bearing weight and the case rated weight, that is, the added test weight is acquired by adding the case rated weight to the current bearing weight.

[0168] Then, it is judged whether the added test weight is greater than the maximum bearing weight, that is, it is judged whether the lowermost case can continue to bear. Continuing to use the above example, the maximum bearing weight of the case is 20 kg, the current bearing weight is 18 kg, and the case rated weight is 2 kg, so at this time, one case can continue to be stacked. If the maximum bearing weight is 19 kg, at this time, one case is added, and the current bearing weight is 20 kg, which is greater than 19 kg, so at this time, the case cannot continue to be added, and if the case is continued to be added, the lowermost case will be damaged.

[0169] Therefore, when the added test weight is greater than the maximum bearing weight, the step of acquiring the stack abnormal prompt information is not performed; when the added test weight is less than or equal to the maximum bearing weight, it is proved that the space is indeed not fully utilized, so the step of acquiring the stack abnormal prompt information is continued to be performed, thereby the related personnel can be reminded, the staff can be adjusted, and the quality of stacking can be improved.

[0170] The implementation principle of the method for detecting the stacking of blow molding products according to the embodiment of the application is as follows: first, the current blow molding product packaging weight is obtained as the current weight, then the size relationship between the current weight and the weight threshold is determined, when the current weight is greater than the weight threshold, it is proved that there may be foreign matter in the box, at this time, the foreign matter warning prompt information is obtained, so that the box can be checked in time. When the current weight is less than the weight threshold, the current decibel value when the box containing the blow molding products is moved is obtained, then whether the current decibel value exceeds the preset decibel value is judged, whether there is a larger space in the box can be determined. If it exceeds, it means that the space in the box is larger, at this time, the blow molding product missing prompt information is obtained, prompting the relevant personnel that there is a blow molding product missing in the box; if it does not exceed, it is proved that the weight of the generated blow molding product may be insufficient, it is proved that the blow molding equipment may be abnormal at this time, the blow molding equipment abnormal prompt information is obtained. Therefore, the packaging quality of the blow molding products can be better detected, and the possibility of unstable stacking of the box due to the packaging problem is reduced as much as possible.

[0171] The embodiment of the application further discloses a blow molding product stacking detection system.

[0172] Referring to Figure 8 , the blow molding product stacking detection system comprises:

[0173] A weight obtaining module 1 is configured to obtain the current blow molding product packaging weight as the current weight.

[0174] A weight determining module 2 is configured to determine the size relationship between the current weight and the weight threshold.

[0175] A first information obtaining module 3 is configured to obtain the foreign matter warning prompt information if the current weight is greater than the weight threshold.

[0176] A decibel obtaining module 4 is configured to obtain the current decibel value when the box containing the blow molding products is moved if the current weight is less than the weight threshold.

[0177] A decibel judging module 5 is configured to judge whether the current decibel value exceeds the preset decibel value.

[0178] A second information obtaining module 6 is configured to obtain the blow molding product missing prompt information if the current decibel value exceeds the preset decibel value.

[0179] A third information obtaining module 7 is configured to obtain the blow molding equipment abnormal prompt information if the current decibel value does not exceed the preset decibel value.

[0180] Specifically, the weight acquisition module 1 acquires the current boxing weight of the blow molding product as the current weight, and sends to the weight determination module 2 connected thereto. Then the weight determination module 2 determines the size relationship between the current weight and the weight threshold, and sends the determined result to the first information acquisition module 3 and the decibel acquisition module 4 connected thereto.

[0181] When the current weight is greater than the weight threshold, the first information acquisition module 3 acquires the foreign matter warning prompt information; when the current weight is less than the weight threshold, the decibel acquisition module 4 acquires the current decibel value when the box containing the blow molding product is moved, and sends to the decibel determination module 5 connected thereto.

[0182] Then the decibel determination module 5 determines whether the current decibel value exceeds the preset decibel value, and sends the determined result to the second information acquisition module 6 and the third information acquisition module 7 connected thereto. If the current decibel value exceeds the preset decibel value, the second information acquisition module 6 acquires the blow molding product missing prompt information; if the current decibel value does not exceed the preset decibel value, the third information acquisition module 7 acquires the blow molding equipment abnormal prompt information. Thus, the boxing quality of the blow molding product can be better detected, and the possibility of unstable stacking of the box due to the boxing problem can be reduced as much as possible.

[0183] The embodiment of the application further discloses an intelligent terminal, comprising a memory and a processor. The memory stores an intelligent computer program. The processor, when running the intelligent computer program, can execute the steps of the blow molding product stacking detection method described above. The intelligent computer program can use known processing programs to judge, detect, weigh and other series of steps on data, so as to realize the detection of the blow molding product stacking.

[0184] The embodiment of the application further discloses a computer readable storage medium which stores a computer program capable of being loaded and executed by a processor to execute the blow molding product stacking detection method as described above, and the computer readable storage medium comprises various storage program codes, such as a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk.

[0185] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made on the structure, shape, principle of the application should be covered within the protection scope of the application.
