Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette sorting, in particular to a cigarette sorting control method and system with adjustable discharging sequence. BACKGROUND

[0002] In recent years, with the diversification of cigarette market demand, the sales of special-shaped cigarettes are increasing, and there is an increasing demand for co-line sorting and co-packaging of special-shaped cigarettes and standard cigarettes. Because the sizes of various special-shaped cigarettes differ greatly, there are requirements for the type and sequence of cigarettes in each layer during packaging. The traditional sorting control method can only sort cigarettes from small to large according to the actual layout of the sorting channel, which cannot meet the requirements of the packaging sequence. The present application provides a sorting control system with adjustable discharging sequence, which can sort cigarettes according to the actual discharging sequence.

[0003] There are two existing cigarette sorting control schemes. The first one is to split an order that needs to control the discharging sequence into multiple orders according to the discharging sequence to meet the requirements of the packaging machine stacking sequence, but the disadvantage is that after splitting an order into multiple orders, an order interval needs to be added between each order, which will greatly reduce the sorting efficiency. The second one is to plan the layout of the sorting channel during the design stage to ensure that the sorting channel layout from small to large meets the requirements of the packaging machine stacking sequence, but the disadvantage is that the fixed channel layout sequence cannot be changed after the sorting brand, and the adaptability to the change of the sales of each brand of cigarettes is weak.

Also, the terms "comprises", "comprising", or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by an "includes a" statement can include additional identical elements not expressly listed after the comma in the statement.

[0043] The features and performance of the present application will be further described in detail below with reference to the embodiments.

[0044] Please refer to Figure 1 A method for controlling the order of cigarette carton dispensing, which comprises the following steps:

[0045] Defining a sorting order table, which contains a plurality of orders, each order contains a plurality of units, and each unit stores the dispensing channel number, dispensing pulse and dispensing quantity. The unit number is the dispensing order number from small to large. The dispensing order can be adjusted by issuing different dispensing channel numbers for each unit.

[0046] Defining a sorting channel parameter table, which contains the distance coding value of each channel to the sorting outlet. The sorting outlet is the position of the last channel.

[0047] The computer system sends the sorting orders to the controller in turn, the controller calculates the smoking pulse of each unit in the order according to the adjustable discharging order sorting algorithm and stores it into the sorting order table;

[0048] When the central belt conveyor is running, the encoder pulse value increases, and when the encoder pulse value reaches the unit smoking pulse, the unit smoking quantity is sent to the smoking channel of the unit;

[0049] The sorting machine receives the channel smoking quantity and distributes the cigarettes to the central conveying belt according to the quantity.

[0050] The adjustable discharging order sorting algorithm comprises the following steps:

[0051] Parameter definition: Assuming that there are N sorting channels in the system, the channels are sequentially Channel 1, Channel 2, Channel 3…Channel N in the conveying direction. Taking the position of the last channel N as the outlet position, the pulse values of each channel to the outlet {L1, L2, L3, …, LN} can be obtained. N For N sorting channels, the pulse value of the central belt passing through when sorting a single cigarette in each channel is defined as {X1, X2, X3, …, XN}. N Define M as the maximum unit number of the order, M should be greater than or equal to N, and define S as the order interval.

[0052] For the mth unit in the ith order, Eim represents the unit smoking pulse, n i,m represents the unit smoking channel number, i,m represents the pulse value of the unit channel to the outlet, represents the pulse value of the unit channel to the outlet, represents the pulse value of the central belt passing through when sorting a single cigarette in the unit channel, Y i,m represents the unit smoking quantity, A i,m represents the pulse value of the cigarette sorted by the unit.

[0053] It can be obtained that

[0054]

[0055] The smoking pulse of the first unit in the first order uses the difference between the pulse value from the first channel to the outlet and the pulse value from the corresponding channel of the unit to the outlet, that is,

[0056]

[0057] The smoking pulse of the second unit in the first order should be the smoking pulse of the first unit plus the pulse value of the cigarette sorted by the first unit, plus the distance pulse value between the first and second unit channels (may be negative), that is,

[0058]

[0059] Similarly

[0060]

[0061] Therefore

[0062]

[0063] E in the formula 1,m-1 Substituting in turn, we get

[0064]

[0065] The smoke out pulse of the first unit in the i-th order should be equal to the smoke out pulse of the first unit in the first order plus the pulse value of all the cigarettes sorted by all the units in the previous i-1 orders, plus the distance pulse value between the first unit in the first order and the first unit in the i-th order channel, plus the i-1 order spacing, that is

[0066]

[0067] According to step C, the smoke out pulse of the m-th unit in the i-th order is calculated using the smoke out pulse of the first unit in the i-th order, that is

[0068]

[0069] Substituting E into the formula, we get i,1 Substituting E into the formula, we get

[0070]

[0071] According to the above, the smoke out pulse of the m-th unit in the i-th order is calculated as follows:

[0072]

[0073] The present application also includes a cigarette sorting control system and method with adjustable discharge sequence, comprising:

[0074] A central belt conveyor connected to the controller for receiving signals from the controller to start and stop feeding the material;

[0075] An encoder installed on the conveyor and connected to the controller for detecting the conveying distance of the central belt conveyor and generating an encoded value;

[0076] A sorting machine containing a plurality of sorting channels installed on the central belt conveyor and connected to the controller for receiving the sorting quantity sent by the controller and sorting the cigarettes onto the central belt conveyor.

[0077] The controller, or PLC, is used to connect the conveyor, sorter, and encoder, control the start and stop of the conveyor, obtain the code value of the conveyor encoder, and control the sorter to sort cigarette cartons;

[0078] The specific operation process is as follows:

[0079] like Figure 1 As shown, the cigarette sorting control system includes a central belt conveyor and a sorter. The sorter has several channels, namely channel 1, channel 2, channel 3, and channel n in the conveying direction. An encoder is installed on the central belt conveyor to detect the conveying distance of the conveyor and generate an encoded value.

[0080] During normal operation, the central belt conveyor runs along the conveying direction, the encoder pulse value increases, and when the controller determines that the pulse value reaches the smoke discharge pulse of a certain channel of the sorter, it controls the sorter to discharge smoke.

[0081] When discharging smoke, the order of smoke discharge for an order follows the order issued by the superior, rather than discharge smoke in sequence according to the channel sequence number, so as to achieve adjustable discharge order.

[0082] The above-described embodiments merely represent specific implementation methods of the present application.
