[0004] The existing automatic packing machine packing bobbin method has a small number of yarns that can be stored in the buffer area, and there are not enough yarns to choose from, which can easily result in a full buffer but no matching, and cannot guarantee the accuracy of the weight matching. SUMMARY

[0034] A weight range of a last cone to be baled is determined based on the bale reference value and the weight sum of all the cones in the marked buffer areas;

[0040] In the embodiment, when performing the counterbalancing, the relationship between the weight of the cone yarn in the unmarked buffer area of the target buffer area and the weight range of the last cone yarn is considered in the process of obtaining the last cone yarn, so that the counterbalancing accuracy is improved.

[0041] In an optional embodiment, when the weight of all the cone yarns in the unmarked buffer area of the target buffer area is less than the weight range of the last cone yarn, the marking of the buffer area where the lightest cone yarn in the marked buffer area is located is removed, the information that the marked buffer area is marked is written in the attribute information of the buffer area where the lightest cone yarn is located, and the step of judging whether the average weight of the cone yarns in the marked buffer area is less than the counterbalancing reference value is performed.

[0042] In the embodiment, when performing the counterbalancing, the relationship between the weight of the cone yarn in the unmarked buffer area of the target buffer area and the weight range of the last cone yarn is considered in the process of obtaining the last cone yarn, so that the counterbalancing accuracy is improved.

[0043] In an optional embodiment, when the weight of all the cone yarns in the unmarked buffer area of the target buffer area is greater than the weight range of the last cone yarn, the marking of the buffer area where the heaviest cone yarn in the marked buffer area is located is removed, the information that the marked buffer area is marked is written in the attribute information of the buffer area where the heaviest cone yarn is located, and the step of judging whether the average weight of the cone yarns in the marked buffer area is less than the counterbalancing reference value is performed.

[0044] In the embodiment, when performing the counterbalancing, the relationship between the weight of the cone yarn in the unmarked buffer area of the target buffer area and the weight range of the last cone yarn is considered in the process of obtaining the last cone yarn, so that the counterbalancing accuracy is improved.

[0045] In an optional embodiment, when the number of removals reaches a preset number threshold, and the counterbalancing result of the current empty lower yarn buffer is still not obtained, the marking and the information that the marked buffer area is marked of all the marked buffer areas are removed, and the counterbalancing is performed again in the next empty lower yarn buffer.

[0066] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0067] With the development of science and technology, the packing method of bobbins in a cotton spinning workshop has changed from manual packing to automatic packing by using an automatic bobbin packing machine.

[0068] An important technical index of the automatic bobbin packing machine is weight matching. Figure 1This is a flowchart illustrating the counterweight method for packaging yarn bobbins using an automatic packaging machine, based on relevant technologies. For example... Figure 1 As shown in the related technology, the process of automatic packaging machine packaging yarn packages includes: after the automatic winding machine produces yarn packages, they are transported to the yarn loading area via belt, and the yarn loading mechanism sends the yarn to the holding device; the yarn is in the holding device, and the holding device is transported on a fixed overhead track, bringing the yarn in the holding device from the yarn loading area to the yarn unloading area; in the yarn unloading area, after detecting that there is yarn in the holding device, the yarn unloading action is executed, and the yarn unloading mechanism removes the yarn from the holding device and places it on the buffer belt; after passing through the single yarn weighing belt, the weight of the yarn is obtained, and according to the weight, it enters the heavy buffer area and the light buffer area. Each buffer area can store 12 yarns. Based on the yarn already stored in the buffer area, the weight is calculated in combination with the weighting algorithm, and finally 12 yarns are selected to be combined into a package.

[0069] In related technologies, the automatic packing machine packs yarn bobbins in a way that the buffer area can only hold a small amount of yarn. There is not enough yarn to choose from, which can easily lead to a situation where the buffer is full but the yarn cannot be dispensed, thus failing to guarantee the accuracy of the weight distribution.

[0070] This invention provides a counterweighting method for an automatic yarn packaging machine. By using the clamps on the aerial track between the yarn feeding mechanism and the empty yarn buffer as buffer areas for yarn counterweighting, the accuracy of the counterweighting is improved.

[0071] According to an embodiment of the present invention, a counterweight method for an automatic yarn packaging machine is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0072] This embodiment provides a counterweight method for an automatic yarn packaging machine, which can be used in the aforementioned mobile terminals, such as central processing units, servers, etc. Figure 2 This is a flowchart of the counterweight method of the automatic yarn packaging machine according to an embodiment of the present invention, as shown below. Figure 2 As shown, the process includes the following steps:

[0073] Step S201: Obtain the weight and variety information of each bobbin at the yarn feeding point.

[0074] After the automatic winding machine produces yarn cones, they are transported to the yarn loading area via belt. The yarn cones are weighed at the loading area, and the weight and type information of each yarn cone is obtained.

[0075] Step S202: When the yarn feeding mechanism performs the yarn feeding action, the weight information and variety information of the yarn package are written into the yarn feeding device.

[0076] Wherein, at most one cheese is placed in each holder, and the attribute information of the holder includes cheese identification information, which is used to identify whether the cheese is placed in the holder.

[0077] It should be noted that the attribute information of the holder also includes holder identification information. Exemplarily, the holder identification information is a holder ID, wherein each holder has a unique holder ID.

[0078] After the weighing of the single cheese is completed, the cheese feeding mechanism performs a cheese feeding action, i.e., placing the cheese into the holder on the aerial track. At the same time of placing the cheese into the holder, the weight information and the variety information of the cheese are written into the holder.

[0079] In step S203, during the operation of the cheese automatic packing machine, when the cheese-containing buffer area reaches the empty cheese feeding buffer, the variety information of the cheese in the cheese-containing buffer area is obtained.

[0080] Wherein, the holder on the aerial track between the cheese feeding mechanism and the empty cheese feeding buffer is taken as the buffer area, and whether the cheese is placed in the buffer area is determined according to the cheese identification information in the holder.

[0081] Each cheese feeding mechanism corresponds to one cheese feeding buffer, and as the cheese automatic packing machine operates, the cheese-containing buffer area advances with the movement of the aerial track belt. When the first cheese-containing buffer area reaches the first empty cheese feeding buffer, the variety information of the cheese in the buffer area is obtained.

[0082] Wherein, the first cheese-containing buffer area refers to the first cheese-containing buffer area that reaches the above-mentioned empty cheese feeding buffer after the cheese automatic packing machine starts to operate. One cheese feeding mechanism corresponds to one cheese feeding buffer, and one cheese feeding buffer includes a unique identification.

[0083] It can be understood that the cheeses on the cheese feeding mechanism include cheeses of multiple varieties, and when the counterweight is performed, the counterweight needs to be performed based on the cheeses of the same variety in the buffer area.

[0084] In step S204, the target buffer area is determined based on the variety information of the cheese in the cheese-containing buffer area.

[0085] Wherein, the buffer area with the same variety information as the variety information of the cheese in the cheese-containing buffer area is determined as the target buffer area.

[0086] In step S205, the weight information of the cheese in the target buffer area is obtained.

[0087] After the target buffer area is determined, the weight information of the cheese in each target buffer area is obtained.

[0088] Step S206, based on the weight information of the bobbin in the target buffer area, determine the bobbin weight reference value of the variety corresponding to the target buffer area.

[0089] After obtaining the weight information of the bobbin in the target buffer area, determine the bobbin weight reference value of the variety according to the weight information of the bobbin in the target buffer area, so as to weight the bobbin in the target buffer area.

[0090] Step S207, based on the weight information of the bobbin in the target buffer area and the bobbin weight reference value, weight the bobbin in the target buffer area, and obtain the weighting result of the current empty lower yarn buffer.

[0091] The weighting result of the current empty lower yarn buffer is the weighting result of the empty lower yarn buffer reached by the first buffer area with a bobbin.

[0092] The bobbin automatic packing machine weighting method provided in the embodiment takes the holder on the air track between the upper yarn mechanism and the empty lower yarn buffer as a buffer area, determines a target buffer area based on the variety information of the bobbin in the buffer area with a bobbin, obtains the weight information of the bobbin in the target buffer area, determines the bobbin weight reference value of the variety corresponding to the target buffer area based on the weight information of the bobbin in the target buffer area, weights the bobbin in the target buffer area based on the weight information of the bobbin in the target buffer area and the bobbin weight reference value, and obtains the weighting result of the current empty lower yarn buffer. The number of buffer areas is large, and there is enough bobbin for selection when weighting, which improves the precision of weighting.

[0093] In the embodiment, a bobbin automatic packing machine weighting method is provided, which can be used in the mobile terminal, such as a central processing unit, a server, and the like, Figure 3 is a flowchart of the bobbin automatic packing machine weighting method according to the embodiment of the application, as shown in the figure, the flowchart includes the following steps: Figure 3

[0094] Step S301, obtain the weight information and variety information of each bobbin at the upper yarn position. For details, see step S201 in the embodiment shown in Figure 2 , which will not be repeated here.

[0095] Step S302, when the upper yarn mechanism performs the upper yarn action, write the weight information and variety information of the bobbin into the holder that releases the bobbin.

[0096] Each holder can hold at most one bobbin, and the attribute information of the holder includes: bobbin identification information, which is used to identify whether the holder holds a bobbin.

[0097] For details, see step S202 in the embodiment shown in Figure 2 , which will not be repeated here.

[0098] ​Step S303, in the process of the bobbin automatic packing machine, when the buffer area where the bobbins are placed reaches the empty lower yarn buffer, the variety information of the bobbins in the buffer area where the bobbins are placed is acquired.

[0099] In the embodiment shown in the figure, the clamp on the air track between the upper yarn mechanism and the empty lower yarn buffer is taken as the buffer area.

[0100] For details, please refer to Figure 2 Step S203 of the embodiment shown in the figure will not be repeated here.

[0101] Step S304, based on the variety information of the bobbins in the buffer area where the bobbins are placed, the target buffer area is determined.

[0102] For details, please refer to Figure 2 Step S204 of the embodiment shown in the figure will not be repeated here.

[0103] Step S305, the weight information of the bobbins in the target buffer area is acquired.

[0104] For details, please refer to Figure 2 Step S205 of the embodiment shown in the figure will not be repeated here.

[0105] Step S306, based on the weight information of the bobbins in the target buffer area, the bobbin weight reference value of the variety corresponding to the target buffer area is determined.

[0106] Specifically, the above step S306 includes:

[0107] Step S3061, based on the weight information of the bobbins in the target buffer area, the average weight of the bobbins in the target buffer area is determined.

[0108] Wherein, after acquiring the weight information of the bobbins in each target buffer area, the average weight of the bobbins in all target buffer areas is calculated. The bobbins in the target buffer area are of the same variety, that is, the current average weight of the bobbins of the variety is acquired.

[0109] Step S3062, the upper limit value of the weight of a single bobbin of the variety corresponding to the target buffer area is acquired.

[0110] Wherein, the upper limit value of the weight of a single bobbin of the variety corresponding to the target buffer area is generally determined by dividing the upper limit value of the whole package weight by the number of bobbins in a package.

[0111] The upper limit value of the whole package weight and the number of bobbins in a package are set by the user. Generally, the upper limit value of the whole package weight is 25100g, and the number of bobbins in a package is generally 12.

[0112] Step S3063, the lower limit value of the weight of a single bobbin of the variety corresponding to the target buffer area is acquired.

[0113] The lower limit value of the single cone yarn weight of the variety corresponding to the target buffer area is generally determined by dividing the lower limit value of the whole package weight by the number of packages.

[0114] The lower limit value of the whole package weight and the number of packages are set by the user. Generally, the lower limit value of the whole package weight is 25000g, and the number of packages is generally 12 cone yarns per package.

[0115] In step S3064, the cone yarn weight average value in the target buffer area, the upper limit value of the single cone yarn weight, and the lower limit value of the single cone yarn weight are used to determine the cone yarn weight reference value.

[0116] After obtaining the cone yarn weight average value in the target buffer area, the upper limit value of the single cone yarn weight, and the lower limit value of the single cone yarn weight, the cone yarn weight reference value is determined according to these values.

[0117] In step S307, the cone yarns in the target buffer area are weighed based on the weight information of the cone yarns in the target buffer area and the cone yarn weight reference value, and the weighing result of the currently empty lower yarn buffer is obtained.

[0118] For details, please refer to Figure 2 Step S207 of the embodiment shown will not be described here.

[0119] The cone yarn automatic packing machine weighing method provided in the embodiment is that the cone yarn weight reference value changes with the pace of the gripper advancing, so that more packages are weighed based on the cone yarns in the existing buffer area, and the number of buffer areas in the embodiment is large, so there are enough cone yarns to choose from when weighing, which improves the weighing accuracy.

[0120] In some optional embodiments, Figure 4 The method flow chart for determining the cone yarn weight reference value according to the embodiment of the application is shown in Figure 4 The above step S3064 includes:

[0121] In step a1, when the lower limit value of the single cone yarn weight is less than the cone yarn weight average value in the target buffer area, and the cone yarn weight average value in the target buffer area is less than the upper limit value of the single cone yarn weight, the cone yarn weight average value in the target buffer area is taken as the cone yarn weight reference value.

[0122] In the formula, Figure 4 In the formula, a is the lower limit value of the single cone yarn weight, b is the upper limit value of the single cone yarn weight, c is the cone yarn weight average value in the target buffer area, and d is the cone yarn weight reference value.

[0123] In step a2, when the lower limit value of the single cone yarn weight is greater than or equal to the cone yarn weight average value in the target buffer area, the lower limit value of the single cone yarn weight is taken as the cone yarn weight reference value.

[0124] Step a3, in the case that the weight average of the cones in the target buffer area is greater than or equal to the upper limit value of the single cone weight, taking the upper limit value of the single cone weight as the cone weight matching reference value.

[0125] In some optional embodiments, Figure 5 is a method flow chart for marking buffer areas according to an embodiment of the application, as Figure 5 shown, the above step S307 includes:

[0126] Step b1, marking the first cone-containing buffer area reaching the empty lower yarn buffer.

[0127] Wherein, the marking is used to represent the identification information of the empty lower yarn buffer, and the cone automatic packing machine includes at least one empty lower yarn buffer.

[0128] It should be noted that the identification of the first cone-containing buffer area can also be marked on the empty lower yarn buffer so as to obtain the corresponding buffer area after obtaining the matching result.

[0129] Step b2, judging whether the average weight of the cones in the marked buffer area is less than the cone weight matching reference value.

[0130] Step b3, in the case that the average weight of the cones in the marked buffer area is less than the cone weight matching reference value, obtaining the buffer area where the heaviest cone in the target buffer area is located, and marking the buffer area where the heaviest cone is located.

[0131] It should be noted that the identification of the buffer area where the cone is located can also be marked on the empty lower yarn buffer so as to obtain the corresponding buffer area after obtaining the matching result.

[0132] Step b4, in the case that the average weight of the cones in the marked buffer area is greater than or equal to the cone weight matching reference value, obtaining the buffer area where the lightest cone in the target buffer area is located, and marking the buffer area where the lightest cone is located.

[0133] Step b5, in the case that the number of the marked buffer areas is less than or equal to the preset number minus 2, executing the step of judging whether the average weight of the cones in the marked buffer area is less than the cone weight matching reference value.

[0134] Wherein, Figure 5 i is the number of the marked buffer areas.

[0135] Step b6, in the case that the number of the marked buffer areas is greater than the preset number minus 2 and less than the preset number, obtaining the weight sum of all the cones in the marked buffer areas.

[0136] Step b7, obtaining a bale reference value based on the bobbin weight reference value and a preset number.

[0137] Wherein, the preset number of bobbins constitutes a bale, and the bale reference value is obtained by multiplying the bobbin weight reference value and the preset number. As mentioned above, the preset number is generally 12.

[0138] Step b8, determining the weight range of the last bobbin to be baled based on the bale reference value and the weight sum of all bobbins in the marked buffer area.

[0139] It can be understood that the bale reference value minus the weight sum of all bobbins in the marked buffer area can obtain the reference weight of the last bobbin, and a value is added or subtracted from the reference weight to obtain the weight range of the last bobbin. Exemplarily, the value can be 10g, or 20g, that is, the weight range of the last bobbin can be the reference weight ± 10g.

[0140] Step b9, determining the buffer area where the last bobbin is located in the unmarked buffer area of the target buffer area based on the weight range of the last bobbin, and marking the buffer area where the last bobbin is located.

[0141] Wherein, in the case of obtaining the weight range of the last bobbin, the buffer area where the last bobbin is located is determined in the unmarked buffer area of the target buffer area, and then the buffer area where the last bobbin is located is marked, that is, the identification of the current empty bottom yarn buffer is marked in the buffer area where the last bobbin is located.

[0142] It can be understood that after the last bobbin is marked, the weight result of the current empty bottom yarn buffer includes the bobbins in the buffer area with the preset number of marked current empty bottom yarn buffer identifications.

[0143] With the operation of the bobbin automatic baling machine, the bobbins in the buffer area with the marked current empty bottom yarn buffer identification flow into the corresponding empty bottom yarn buffer, and the bottom yarn mechanism obtains the preset number of bobbins in the bottom yarn buffer to combine a bale, and completes the bobbin baling.

[0144] In some optional embodiments, Figure 6 is a method flowchart for determining the last bobbin according to an embodiment of the application, as Figure 6 shown, the above step b9 includes:

[0145] Step b91, in the case that there is at least one bobbin in the buffer area in the unmarked buffer area of the target buffer area whose weight is within the weight range of the last bobbin, obtaining the last bobbin.

[0146] The last bobbin is the bobbin whose weight is closest to the package reference value among the bobbins in the unmarked cache area of the target cache area.

[0147] It can be understood that if the unmarked cache area of the target cache area has a bobbin whose weight is within the weight range of the last bobbin, the bobbin whose weight is closest to the package reference value is obtained among the bobbins whose weights are added to the weights of the aforementioned marked preset number-1 bobbins.

[0148] In step b92, the cache area in which the last bobbin is located is marked.

[0149] After the last bobbin is obtained, the cache area in which the last bobbin is located is marked.

[0150] It should be noted that the identifier of the cache area of the last bobbin can also be marked on the empty lower yarn cache, so that the corresponding cache area can be obtained after the counterweight result is obtained.

[0151] In step b93, when the weights of all the bobbins in the unmarked cache area of the target cache area are less than the weight range of the last bobbin, the mark of the cache area in which the lightest bobbin in the marked cache area is removed, the marked information is written in the attribute information of the cache area in which the lightest bobbin is located, and the step of judging whether the average weight of the bobbins in the marked cache area is less than the bobbin counterweight reference value is executed.

[0152] The weights of all the bobbins in the unmarked cache area of the target cache area are less than the weight range of the last bobbin, that is, the weights of all the bobbins in the unmarked cache area of the target cache area are less than the minimum value in the weight range of the last bobbin, and the weight of the marked bobbin is too light to match the heavy yarn.

[0153] It should be noted that the removed and marked cache area no longer participates in the acquisition of the counterweight result of the empty lower yarn cache. That is, when the lightest bobbin in the unmarked cache area of the target cache area is obtained, the marked cache area is not considered in the case that the average weight of the bobbins in the marked cache area is greater than or equal to the bobbin counterweight reference value.

[0154] In step b94, when the weights of all the bobbins in the unmarked cache area of the target cache area are greater than the weight range of the last bobbin, the mark of the cache area in which the heaviest bobbin in the marked cache area is removed, the marked information is written in the attribute information of the cache area in which the heaviest bobbin is located, and the step of judging whether the average weight of the bobbins in the marked cache area is less than the bobbin counterweight reference value is executed.

[0155] In the target buffer area, the weight of all the bobbins in the unmarked buffer area is greater than the weight range of the last bobbin, that is, the weight of all the bobbins in the unmarked buffer area is greater than the maximum value in the weight range of the last bobbin, and the weight of the marked bobbin is too heavy and there is no light bobbin to match.

[0156] It should be noted that the removed and marked buffer area no longer participates in the acquisition of the matching weight result of the current empty lower yarn buffer. That is, in the case where the average weight of the bobbins in the marked buffer area is less than the bobbin matching weight reference value, when the buffer area in which the heaviest bobbin in the unmarked target buffer area is located is acquired, the marked buffer area will not be considered.

[0157] Further, generally, there will not be a case where the weight of part of the bobbins in the unmarked buffer area of the target buffer area is greater than the weight range of the last bobbin, and the weight of part of the bobbins in the unmarked buffer area of the target buffer area is less than the weight range of the last bobbin, because:

[0158] 1. The weight of any two single yarns will not differ by more than 50g or so. If both greater and less exist, the weight difference of the single yarns will be greater than the difference between the upper and lower limits of the whole package weight, which is generally 100g; 2. Overall, the algorithm prioritizes the selection of the two ends of the yarn during the matching process, that is, the lightest and heaviest bobbins in the buffer are selected first, so that the weight of the remaining yarns is in the middle.

[0159] Step b95, in the case where the removal times reach the preset number of times threshold and the matching weight result of the current empty lower yarn buffer is still not obtained, the marks and marked information of all the marked buffer areas are removed, and the matching is performed again in the next empty lower yarn buffer.

[0160] Exemplarily, the preset number of times threshold is 2. In the case where the removal times reach the preset number of times threshold and the matching weight result of the current empty lower yarn buffer is still not obtained, the marks and marked information in the aforementioned preset number-1 marked buffer areas are removed, so that the aforementioned matching is performed again when the first bobbin-containing buffer area reaches the next empty lower yarn buffer.

[0161] It can be understood that, with the operation of the bobbin automatic packing machine, the bobbins that are not successfully matched flow to the next empty lower yarn buffer along the belt, and at the same time, the buffer areas on the air track between the yarn feeding mechanism and the empty lower yarn buffer are also updated, and the matching weight reference value and the bobbin weight range are also updated, so that the next empty lower yarn buffer is matched again according to the updated data.

[0162] The bobbin automatic packing machine weight matching method provided by the embodiment is that the bobbin weight matching reference value is constantly changing with the pace of the gripper advancing, so that more packages are matched based on the bobbin in the existing buffer area, and the number of the buffer area is large, so that there is enough bobbin for selection during weight matching, the precision of weight matching is improved, and even if individual yarn is not matched out and left in the gripper, it will not cause the belt to be blocked and the transport belt to be blocked.
