[0069] At present, paper enterprises mainly adopt the following two ways to provide finished paper core tubes: (1) According to the production plan, the paper core tubes are transported to the unloading station of the workshop, and then the paper core tubes of each product width are manually transported to the temporary storage area near the rewinding machine; (2) After the paper core tubes are transported to the workshop, the cutting machine operator needs to cut the paper core tubes according to the production plan, and then manually transport the paper core tubes to the temporary storage area near the rewinding machine.
[0070] If the paper core tube is manually fed into the rewinder to form a long root paper core tube, the feeding sequence of the multiple product width paper core tubes is prone to error, the work efficiency is low, and a large amount of manpower is required, the labor intensity of workers is large, especially when 12-inch paper core tubes are used, two people are required to work together to feed the paper core tube into the rewinder, and the work intensity is particularly large. Moreover, the current feeding is not adapted to the dispatching of the paper core tube, which increases the production cost of the papermaking enterprise.
[0071] To solve the above technical problems, the paper core tube scheduling method provided by the present application is applied to a paper core tube scheduling system, as shown in the accompanying drawings, Figure 1 The scheduling system includes a plurality of channels 4 and a buffer area above the channels 4, the length of each channel 4 is the same, and the width of each channel 4 includes at least two width values; the scheduling method includes: based on the current production order of the paper core tube, the remaining storage amount of the paper core tube in the buffer area, and the number of available channels, determining the number of product width types and the number of width products corresponding to each product width, the product width representing the length of the paper core tube, and the product width corresponding to the width of the channel; based on the product width and the channel width, determining the number of pre-occupied channels of the paper core tube; if the number of available channels is less than the number of pre-occupied channels, reducing the remaining storage amount of the paper core tube in the buffer area until the number of available channels is greater than or equal to the number of pre-occupied channels; if the number of available channels is greater than or equal to the number of pre-occupied channels, based on the product width, the number of width products corresponding to each product width, and the number of pre-occupied channels, the paper core tube corresponding to each product width in the current production order is respectively distributed to the channels corresponding to the number of pre-occupied channels; if the number of pre-occupied channels of the paper core tube in the next production order is greater than the number of available channels, stop feeding to the buffer area; based on the dispatching of the paper core tube out of the warehouse of the last production order, if the number of paper core tubes of the next production order is less than or equal to the remaining storage amount of the buffer area, continue feeding to the buffer area. The paper core tube scheduling method of the present application avoids manual feeding of the paper core tube into the rewinder, improves the feeding efficiency of the paper core tube into the rewinder, reduces the work intensity of the workers, can sequentially feed the paper core tube into the rewinder according to the demand of the current production order, prevents the feeding sequence of the paper core tube from being wrong, and matches the dispatching of the paper core tube out of the warehouse to automatically adjust the warehouse entry and exit of the channel according to the current production order and the next production order, realizes the automation and intelligence of the paper core tube preparation and distribution, and reduces the production cost of the long root paper core tube.
[0072] It should be noted that, as shown in Figure 1 The end of the paper core tube frame 1 in the figure is the warehouse entry end, and the end close to the conveying line 6 in the figure is the warehouse exit end. The scheduling system further includes a conveying line 6 connected to each channel 4, and an automatic crane 3.

The flow direction of the paper core tube 5 is that the paper core tube 5 is sent to the corresponding paper core tube frame 1 by using a forklift or other transportation tools, the paper core tube 5 required by the production order is transferred from the frame to the channel corresponding to the paper core tube frame 1 by the automatic trolley 3 according to the warehousing scheduling, and then the paper core tube 5 is conveyed from the channel to the conveying line 6 connected with each channel according to the dispatching, and is conveyed to the end of the conveying line 6 on the conveying line 6, Figure 1 The arrow in the figure indicates the conveying direction of the dispatching, the end of the conveying line 6 is the part of the conveying line 6 corresponding to the channel 1 along the conveying direction, and then the paper core tube 5 is conveyed to the rewinder through the conveying line to be rewound in sequence.

[0084] In this embodiment, if the number of available channels is less than the number of pre-occupied channels, it means that the space of the channel cannot meet the demand of the production order sheet, and the remaining storage of the paper core tube in the buffer area is reduced until the number of available channels is greater than or equal to the number of pre-occupied channels, thereby meeting the demand of the production order sheet.
[0085] S4, if the number of available channels is greater than or equal to the number of pre-occupied channels, based on the product width, the number of product widths corresponding to each product width, and the number of pre-occupied channels, respectively distribute the paper core tube corresponding to each product width in the current production order sheet to the channel corresponding to the number of pre-occupied channels.

[0088] In one embodiment, the paper core tube corresponding to each product width in the current production order is respectively distributed to the channel corresponding to the number of pre-occupied channels, comprising: obtaining the feeding time of a single channel corresponding to the current production order, the feeding time of the single channel, the feeding time of the single channel, and the inventory consumption time of the single channel; based on the current production order, the feeding time of the single channel, the feeding time of the single channel, the feeding time of the single channel, and the inventory consumption time of the single channel, it is determined that the paper core tube corresponding to any product width occupies 2 channels or 1 channel.

[0090] In one embodiment, based on the current production order, the feeding time of a single channel, the loading time of a single channel, the loading times of a single channel, the inventory consumption time of a single channel, the buffer area time determination formula determines that any product width corresponds to a paper core tube occupying 2 channels or occupying 1 channel, including: based on the current production order, the product width type number of the paper core tube and the product width quantity corresponding to each product width are determined; based on the product of the loading time of a single channel and the loading times of a single channel, the total loading time of a single channel of the current production order is determined; based on the sum of the feeding time of a single channel and the total loading time of a single channel, the total feeding time of a single channel of the current production order is determined; if the total feeding time of a single channel is less than the inventory consumption time of a single channel, it is determined that the paper core tube corresponding to any product width occupies 1 channel; if the total feeding time of a single channel is greater than or equal to the inventory consumption time of a single channel, it is determined that the paper core tube corresponding to any product width occupies 2 channels.

[0093] Wherein, t s1 is the feeding time of a single channel, that is, the time from receiving the material taking signal to sending the full paper core tube frame to the set position; t s2 is the loading time of a single channel, that is, the time for the automatic crane to load the paper core tube required by the production order to the corresponding channel; m is the loading times of a single channel, that is, the number of times the automatic crane loads the full paper core tube on the buffer area of a single channel; t x is the inventory consumption time of a single channel, that is, the time for all the paper core tubes on a single channel to be completely consumed by the production order.
[0094] S5, if the number of pre-occupied channels of the paper core tube in the next production order is greater than the number of available channels, stop feeding to the buffer area.
[0095] In this embodiment, if the number of pre-occupied channels of the paper core tube in the next production order is greater than the number of available channels, it means that the space of the buffer area on the channel is not enough, and the paper core tube of the next production order does not have enough space to store, so the feeding to the buffer area is stopped.
[0096] S6, based on the out-of-stock scheduling of the paper core tube of the last production order, if the number of paper core tubes of the next production order is less than or equal to the remaining storage capacity of the buffer area, continue feeding to the buffer area.
[0097] In the embodiment, based on the dispatch of the paper core tube of the last production order, if the number of the paper core tube of the next production order is less than or equal to the remaining storage capacity of the buffer area, that is, the paper core tube of the last production order is continuously dispatched, and the number of the paper core tube of the next production order is less than or equal to the remaining space capacity of the buffer area, it indicates that there is more unoccupied storage space in the buffer area on the channel, and then the feeding to the buffer area is continued, so that the continuity of the dispatch and the storage is maintained, and the production efficiency is improved.
[0098] In one embodiment, the production order includes a sequence number, the sequence number is a combination of the numbers of the paper core tubes of the multiple product widths in a set of paper core tubes arranged from small to large, and the number of any product width paper core tube in the sequence number and the channel number of the channel where the paper core tube is located form a paper core tube array.
[0099] In one embodiment, as shown in Figure 3 the dispatch includes:
[0100] S61, determining the dispatch paper core tube queue corresponding to the shortest transport time in the last production order by a first transport time calculation formula of a set of paper core tubes.
[0101] In the embodiment, the last production order of a certain channel is dispatched first to increase the channel with remaining space, so all the dispatch combinations are exhausted, and the dispatch is performed by determining the dispatch paper core tube queue corresponding to the shortest transport time in the last production order by a first transport time calculation formula of a set of paper core tubes, so that the turnover time of the channel is shortened, the speed of the dispatch and the storage is improved, and the production efficiency is improved.
[0102] S62, taking the paper core tube array corresponding to any number X of the dispatch paper core tube queue as a starting point, and sequentially polling the channels from the channel number Y to the maximum channel number Y max in the paper core tube array corresponding to any number X.
[0103] In the embodiment, the paper core tube array corresponding to any number X of the dispatch paper core tube queue is taken as a starting point, the channel corresponding to the starting point is preferentially selected as the channel close to the terminal of the transport line (i.e., the channel close to the dispatch exit), and the channels from the channel number Y to the maximum channel number Y max are sequentially polled and judged to preferentially dispatch the paper core tube from the channel close to the terminal of the transport line.
[0104] S63, judging whether the number X corresponding to the paper core tube at the position of the polling channel and the polling channel on the transport line is i less than any number X.
[0105] In the embodiment, since the numbers of the paper core tubes corresponding to the multiple product widths in a set of paper core tubes are arranged from small to large, the polling aims to let the paper core tubes with numbers less than X be discharged first, so the polling result needs to be judged.
[0106] S64, if yes, wait for the number X i The corresponding paper core tube is discharged through the channel where the paper core tube with any number X is located, if no, the paper core tube with any number X is discharged through the end of the conveying line.
[0107] In the embodiment, if the number X i of the paper core tube corresponding to the position of the conveying line corresponding to the polling channel is less than any number X, the paper core tube with the number X i is discharged through the channel where the paper core tube with any number X is located, and the paper core tube with the number X is not discharged temporarily; if the number X i of the paper core tube corresponding to the position of the conveying line corresponding to the polling channel is greater than any number X, the paper core tube with any number X is discharged through the end of the conveying line first.
[0108] S65, if the number X i of the corresponding paper core tube has passed through the channel where the paper core tube with any number X is located, the paper core tube with any number X is discharged through the end of the conveying line.
[0109] S66, if the number X i of the corresponding paper core tube has not passed through the channel where the paper core tube with any number X is located, continue to judge whether the number X i of the paper core tube corresponding to the position of the conveying line corresponding to the polling channel is less than any number X, until the discharge scheduling of the production order is completed.
[0110] In the embodiment, if the number X i of the corresponding paper core tube has not passed through the channel where the paper core tube with any number X is located, it means that the paper core tube with the number X i is still in the conveying process, continue to judge whether the number X i of the paper core tube corresponding to the position of the conveying line corresponding to the polling channel is less than any number X, until the discharge scheduling of the production order is completed.
[0111] In one embodiment, the first conveying time calculation formula is:
