Technical field

The invention relates to the technical field of cigarette sorting, and in particular to a cigarette sorting control method and system with adjustable discharging sequence.

Background technique

In recent years, with the diversified development of cigarette market demand, the sales of special-shaped cigarettes have increased. Special-shaped cigarettes and standard cigarettes are sorted on the same line, and the demand for co-packaging is increasing day by day. Because the sizes of various types of special-shaped cigarettes vary greatly, there are requirements for the type and order of cigarettes in each layer when packaging. The traditional sorting control method can only sort smoke from small to large according to the actual sorting channel layout according to the order, and cannot meet the packaging stacking sequence requirements. The invention provides a sorting control system with adjustable discharging sequence, which can sort cigarettes according to the actual required discharging sequence.

There are two existing cigarette sorting control solutions. The first is to split an order that needs to control the discharging sequence into multiple orders according to the discharging sequence to meet the stacking sequence requirements of the packaging machine. However, the disadvantage is that after splitting an order into multiple orders, each order Adding order spacing will greatly reduce the sorting efficiency. The second is to plan the layout of the sorting channels at the design stage to ensure that the arrangement of the sorting channels from small to large meets the stacking sequence of the packaging machine. However, the disadvantage is that the sorting brand cannot be changed after the channel arrangement is fixed. Weak adaptability to sales changes of various brands of cigarettes.

Contents of the invention

The purpose of the present invention is to provide a cigarette sorting control method and system with adjustable discharging sequence in order to solve the problems of low sorting efficiency and weak adaptability of the current cigarette sorting control system. In the process, the central belt encoding value is used for position tracking control, the encoding value of each channel is measured, and the cigarette output encoding value of each channel is calculated according to the order, so as to realize cigarette sorting control with adjustable discharging sequence.

The technical solution of the present invention is as follows:

A cigarette sorting control method with adjustable discharging sequence includes the following steps:

Set up a sorting order table. The order table includes at least two orders. Each order includes at least two units. The smoke outlet channel number, smoke outlet pulse and smoke outlet quantity are stored in the unit. The unit number is the order of smoke outlet from small to large. No., the discharging sequence is controlled and adjusted by assigning different smoke outlet channel numbers to each unit;

Set up the sorting channel parameter table. The channel parameters are the distance coding values between each channel and the sorting exit. The sorting exit is the position of the last channel;

The computer system issues the sorting orders to the controller in sequence, and the controller calculates the smoke pulses of each unit in the order based on the sorting algorithm with adjustable discharging sequence, and stores them in the sorting order table;

When special-shaped cigarettes and standard cigarettes are sorted on the same line, the cigarettes are automatically sorted according to the actual packaging order, rather than arranged according to channels. The order of sorting from small to large reduces labor costs and avoids the problem of unstable packaging stacks caused by the order of cigarette discharge.

2. A cigarette sorting control method and system with adjustable discharging order. When discharging cigarettes, the order of cigarette discharging for an order is based on the order of cigarette discharging issued by the encoder, instead of sequentially discharging cigarettes according to the channel sequence number. To achieve adjustable discharging sequence.

Without further limitation, an element defined by the statement "comprises a..." does not exclude the presence of additional identical elements in a process, method, article, or apparatus that includes the stated element.

The features and performance of the present invention will be described in further detail below with reference to examples.

Please refer to Figure 1, a cigarette sorting control method with adjustable discharging sequence includes the following steps:

Define the sorting order table. The order table contains several orders. Each order contains several units. The smoke outlet channel number, smoke outlet pulse and smoke outlet quantity are stored in the unit. The unit number from small to large is the smoke outlet sequence number. The discharging sequence can be adjusted by assigning different smoke outlet channel numbers to each unit;

Define the sorting channel parameter table. The channel parameters are the distance coded values from each channel to the sorting exit, and the sorting exit is the position of the last channel;

The computer system issues the sorting orders to the controller in sequence, and the controller calculates the smoke pulses of each unit in the order based on the sorting algorithm with adjustable discharging sequence, and stores them in the sorting order table;

When the central belt conveyor is running, the encoder pulse value increases. When the encoder pulse value reaches the unit smoke emission pulse, the number of smoke emitted by the unit is sent to the smoke outlet channel of the unit;

The sorting machine receives the number of cigarettes coming out of the channel and distributes the cigarettes according to the quantity to the central conveyor belt conveyor.

The sorting algorithm with adjustable discharging sequence includes the following steps:

Parameter definition: It is assumed that there are N sorting channels in the system, and the conveying direction is channel 1, channel 2, channel 3... channel N. Taking the position of the last channel N as the exit position, the pulse values {L ₁ , L ₂ , L ₃ ,..., L _N } from each channel to the exit can be obtained. For N sorting channels, the pulse value of the center belt when each channel sorts a single cigarette is defined as {X ₁ , X ₂ , X ₃ ,..., X _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 spacing.

For the m-th unit in the i-th order, use E _i,m to represent the smoke emission pulse of the unit, and n _i,m to represent the smoke emission channel number of the unit. Indicates the pulse value from the unit channel to the outlet,/> Indicates the pulse value of the center belt when the unit channel is sorting a single cigarette. Y _i,m indicates the number of cigarettes emitted from the unit. A _i,m indicates the pulse value occupied by the cigarettes sorted by the unit.

It can be concluded that

The smoke emission 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

The smoke emission pulse of the second unit in the first order should be the smoke emission pulse of the first unit plus the pulse value occupied by the cigarettes sorted by the first unit, plus the sum of the first and second unit channels. The distance between pulse values (may be negative), that is

Same reason

It can be concluded from this

Bringing in E _{1, m-1} in the formula in turn, we can get

The smoke emission pulse of the 1st unit in the i-th order should be equal to the smoke emission pulse of the 1st unit of the 1st order plus the pulse value occupied by the cigarettes sorted by all units of the previous i-1 order, and then Add the distance pulse value between the 1st unit of the 1st order and the 1st unit channel of the i-th order, plus the i-1 order spacing, that is

According to step C, use the smoke emission pulse of the 1st unit of the ith order to calculate the smoke emission pulse of the mth unit of the ith order, then

Root Substitute E _i,1 into the formula, then

To sum up, the smoke pulse of the m-th unit in the i-th order is calculated as follows:

The invention also includes a cigarette sorting control system and method with adjustable discharging sequence, including:

The central belt conveyor is connected to the controller and is used to receive signals from the controller to start and stop feeding materials;

The encoder is installed on the conveyor and connected to the controller. It is used to detect the conveying distance of the central belt conveyor and generate a coded value;

The sorting machine contains several sorting channels, is installed on the central belt conveyor, is connected to the controller, and is used to receive the sorting quantity sent by the controller and sort the cigarettes onto the central belt conveyor.

The controller, that is, PLC, is used to connect the conveyor, sorter and encoder, control the start and stop of the conveyor, obtain the encoding value of the conveyor encoder, and control the sorter to sort cigarettes;

The specific operation process is as follows:

As shown in Figure 1, the cigarette sorting control system includes a central belt conveyor and a sorter. The sorter contains several channels, which are channel 1, channel 2, channel 3...channel n in order of transportation direction. An encoder is installed on the central belt conveyor to detect the conveying distance of the conveyor and generate a coded value.

During normal operation, the central belt conveyor runs along the conveying direction, and the encoder pulse value increases. When the controller determines that the pulse value reaches the smoke emission pulse of a certain channel of the sorter, it controls the sorter to emit smoke.

When emitting smoke, the order of emitting smoke for an order is based on the order of emitting smoke issued by the superior, rather than emitting smoke sequentially according to the channel sequence number, so that the order of discharging materials can be adjusted.

The above-described embodiments only express specific implementation modes of the present application, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of protection of the present application. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the technical solution of the present application, and these all fall within the protection scope of the present application.
